Personal motivation is a key factor in the service of foster care, impending both on the welfare of the child and on the satisfaction of the carer. This paper explores the benefits, challenges and dilemmas involved in the job of professional (i.e. state-supported) foster carer in Romania–a country where the issue of child protection has drawn a great deal of international attention over the last thirty years. The principal hypothesis concerns whether the benefits, challenges and dilemmas identified by foster carers are influenced by the factors that led to their taking up this kind of work. Quantitative research was conducted using a questionnaire as the main tool. The paper takes a descriptive, cross-sectional and multifactorial approach. Sampling was carried out by self-selecting method, and the study involved 51 participants. The research project identified a statistically significant variation in the challenges and dilemmas reported by foster carers. Thus, the results of the study show that the majority of the carers indicate a primarily intrinsic motivation for their work. By way of conclusion, it is argued that social workers, operating in collaboration with multidisciplinary teams, can offer carers support in managing more difficult periods in the child–carer relationship, thus enhancing the sustainability of the foster care service.

This paper examines how to maximize contribution in public good dilemmas by arranging people into homogeneous or heterogeneous subgroups. Past studies on the effect of homogeneity of efficacy have exclusively manipulated group composition in their experimental designs, which might have imposed a limit on ecological validity because group membership may not be easily changed in reality. In this study, we maintained the same group composition but varied the subgroup composition. We developed a public good dilemmas paradigm in which participants were assigned to one of the four conditions (high- vs. low-efficacy; homogeneous vs. heterogeneous subgroup) to produce their endowments and then to decide how much to contribute. We found that individuals in homogeneous and heterogeneous subgroups produced a similar amount and proportion of contribution, which was due to the two mediating effects that counteracted each other, namely (a) perceived efficacy relative to subgroup and (b) expectation of contribution of other subgroup members. This paper demonstrates both the pros and cons of arranging people into homogeneous and heterogeneous subgroups of efficacy. [ABSTRACT FROM AUTHOR]

The popularity of online information generally experiences a rising and falling evolution. This paper considers the “burst”, “peak”, and “fade” key events together as a representative summary of popularity evolution. We propose a novel prediction task—predicting when popularity undergoes these key events. It is of great importance to know when these three key events occur, because doing so helps recommendation systems, online marketing, and containment of rumors. However, it is very challenging to solve this new prediction task due to two issues. First, popularity evolution has high variation and can follow various patterns, so how can we identify “burst”, “peak”, and “fade” in different patterns of popularity evolution? Second, these events usually occur in a very short time, so how can we accurately yet promptly predict them? In this paper we address these two issues. To handle the first one, we use a simple moving average to smooth variation, and then a universal method is presented for different patterns to identify the key events in popularity evolution. To deal with the second one, we extract different types of features that may have an impact on the key events, and then a correlation analysis is conducted in the feature selection step to remove irrelevant and redundant features. The remaining features are used to train a machine learning model. The feature selection step improves prediction accuracy, and in order to emphasize prediction promptness, we design a new evaluation metric which considers both accuracy and promptness to evaluate our prediction task. Experimental and comparative results show the superiority of our prediction solution. [ABSTRACT FROM AUTHOR]

Background: Impairments in social cognition have been described in several psychiatric and neurological disorders. Given the importance of the relationship between social cognition and functioning and quality of life in these disorders, there is a growing interest in social cognition remediation interventions. The aim of this study was to carry out a systematic mapping review to describe the state of the art in social cognition training and remediation interventions. Methods: Publications from 2006 to 2016 on social cognition interventions were reviewed in four databases: Scopus, PsycINFO, PubMed and Embase. From the initial result set of 3229 publications, a final total of 241 publications were selected. Results: The study revealed an increasing interest in social cognition remediation interventions, especially in the fields of psychiatry and psychology, with a gradual growth in the number of publications. These were frequently published in high impact factor journals and underpinned by robust scientific evidence. Most studies were conducted on schizophrenia, followed by autism spectrum disorders. Theory of mind and emotional processing were the focus of most interventions, whilst a limited number of studies addressed attributional bias and social perception. Targeted interventions in social cognition were the most frequent practice in the selected papers, followed by non-specific treatment interventions and broad-based interventions. Conclusions: Research in social cognition remediation interventions is growing. Further studies are needed on attributional bias and social perception remediation programs, while the comparative efficacy of different interventions also remains unclear. [ABSTRACT FROM AUTHOR]

This paper analyzes seasonal effects and their potential drivers in charitable giving. We conduct two studies to analyze whether donations to the German Red Cross differ between the Christmas season and summer. In study 1 we find that in the pre-Christmas shopping season prosocial subjects almost donate 50% less compared to prosocials in summer. In study 2 we replicate the low donations in the Christmas season. In an extensive questionnaire we control for several causes of this effect. The data suggest that the higher prosocials’ self-reported stress level, the lower the donations. The higher their relative savings, the lower the giving. Our questionnaire rules out that “donation fatigue” matters. That is, donations do not depend on the number of charitable campaigns subjects are confronted with and their engagement in these activities during Christmas season outside the lab.

There have been decades of research on the usability and educational value of augmented reality. However, less is known about how augmented reality affects social interactions. The current paper presents three studies that test the social psychological effects of augmented reality. Study 1 examined participants’ task performance in the presence of embodied agents and replicated the typical pattern of social facilitation and inhibition. Participants performed a simple task better, but a hard task worse, in the presence of an agent compared to when participants complete the tasks alone. Study 2 examined nonverbal behavior. Participants met an agent sitting in one of two chairs and were asked to choose one of the chairs to sit on. Participants wearing the headset never sat directly on the agent when given the choice of two seats, and while approaching, most of the participants chose the rotation direction to avoid turning their heads away from the agent. A separate group of participants chose a seat after removing the augmented reality headset, and the majority still avoided the seat previously occupied by the agent. Study 3 examined the social costs of using an augmented reality headset with others who are not using a headset. Participants talked in dyads, and augmented reality users reported less social connection to their partner compared to those not using augmented reality. Overall, these studies provide evidence suggesting that task performance, nonverbal behavior, and social connectedness are significantly affected by the presence or absence of virtual content.

Current literature presents conflicting findings concerning the effect of religiosity on attitudes towards redistribution. This paper attempts to reconcile these findings by arguing that the belief and social behavior dimensions of religiosity affect support for redistribution via different mechanisms, and that these effects are moderated by state welfare generosity. Using multilevel path analysis models on data from the World Values Survey, we show that the effect of the religious belief on attitudes towards redistribution is mediated by competing personal orientations—prosocial values and conservative identification—while the religious social behavior dimension significantly decreases support for redistribution via increased levels of happiness. Lower levels of welfare generosity increase the positive effect of prosocial orientations and weaken the negative effect conservative identification, leading to positive or null indirect effect of religiosity. These findings show the importance of taking into account the multiple dimensions of religiosity and institutional context when studying the relationship between religion and redistribution attitudes.

Many national (US) and International guidelines for physical activity provide guidance that under-active and sedentary adults can begin by accumulating moderate-to-vigorous physical activity (MVPA) in bouts as brief as 10 minutes. This guidance fits well with Goal Setting theory in that goals should be realistic and achievable, and is also consistent with Social Cognitive theory since achieving small goals should boost self-efficacy and thus, encourage continued physical activity. In contrast, Behavioral Economics might suggest that fewer, longer bouts would be more conducive to the adoption of physical activity due to the costs incurred with each separate bout of MVPA. This paper examines patterns of MVPA adoption among a sample of under-active adults from the perspective of goal setting theory and behavioral economics to explore specific strategies to help people who are in the early stages of PA activity adoption. Under-active men and women (N = 225; mean age = 46 ± 10; mean BMI = 28 ± 4.48) who enrolled in a PA intervention participated in a single goal setting session at enrollment. Participants were encouraged to set realistic goals and to increase their activity to meet national recommendations (150 minutes/week of moderate to vigorous physical activity [MVPA]) by the 6-month follow up. This process included identifying a specific frequency goal (days/week) and session duration goal (minutes/day). At baseline, participants reported average weekly MVPA of 14.59 min (± 24), which increased to an average of 140.52 (± 143.55) at 6 months. MVPA goals at baseline averaged 33.24 min/day (± 18.08) and 3.85 days/week (± 1.31). Analyses showed that longer session duration goals set at baseline were associated with more weekly minutes of MVPA at 6 months (b = 1.26, SE = 0.58, t = 2.17, p = 0.03). There was no significant association between goals for number of days per week (frequency) or total minutes of weekly MVPA (minutes x frequency) and MVPA at 6 months. Widely promoted guidelines for uptake of physical activity recommend accumulating physical activity in bouts as short as 10 minutes. This recommendation may ultimately hinder the adoption of physical activity among under-active and sedentary individuals. For the purposes of behavioral adoption of MVPA, more ambitious session duration goals appear to result in higher levels of physical activity participation. [ABSTRACT FROM AUTHOR]

We introduce a new agent-based model of opinion dynamics in which binary opinions of each agent can be measured and described regarding both pre- and post-influence at both of two levels, public and private, vis-à-vis the influence source. The model combines ideas introduced within the q-voter model with noise, proposed by physicists, with the descriptive, four-dimensional model of social response, formulated by social psychologists. We investigate two versions of the same model that differ only by the updating order: an opinion on the public level is updated before an opinion on the private level or vice versa. We show how the results on the macroscopic scale depend on this order. The main finding of this paper is that both models produce the same outcome if one looks only at such a macroscopic variable as the total number of the individuals with positive opinions. However, if also the level of internal harmony (viz., dissonance) is measured, then significant, qualitative differences are seen between these two versions of the model. All results were obtained simultaneously within Monte Carlo simulations and analytical calculations. We discuss the importance of our studies and findings from three points of view: the theory of phase transitions, agent-based modeling of social systems, and social psychology.

This paper examines social class-based differences in influence in online review contexts. We explore four mechanisms for how a review writer’s social class may affect readers’ evaluations of the organization. First, we argue that, via a “contagion” process, organizations reviewed by higher-class individuals will be evaluated more positively than organizations reviewed by lower-class individuals. Second, we expect that higher-class reviewers will be seen as more knowledgeable; thus, their opinions will be more influential in shaping others’ opinions. Third, we expect that reviewers will be seen more influential when they review organizations that match their social class. Fourth, we expect people to be more influenced by those who share their own class background. A large-scale observational study of reviews (N = 1,234,665) from finds support for the contagion, the organization-reviewer social class matching, and the reviewer-participant social matching hypotheses, but disconfirms the hypothesis that higher-class reviewers are always treated as having more expertise. Two experimental studies (N = 354 and N = 638) demonstrate that reviewer class plays a causal role in both a contagion process and in an assumption of higher-class knowledge process, but do not provide evidence for the reviewer-participant social matching hypothesis.

McPherson’s Blau space and affiliation ecology model is a powerful tool for analyzing the ecological competition among social entities, such as organizations, along a combination of sociodemographic characteristics of their members. In this paper we introduce the R-based Graphical User Interface (GUI) package Blaunet, an integrated set of tools to calculate, visualize, and analyze the statuses of individuals and social entities in Blau space, parameterized by multiple sociodemographic traits as dimensions. The package is able to calculate the Blau statuses at the nodal, dyadic, and meso levels based on three types of information: sociodemographic characteristics, group affiliations (e.g., membership in groups/organizations), and network ties. To facilitate this, Blaunet has the following five main capabilities, it can: 1) identify a list of possible salient dimensions; 2) calculate, plot, and analyze niches for social entities by measuring the social distance along the salient dimensions between individuals affiliated with them; 3) generate Blau bubbles for individuals, thereby allowing the study of interpersonal influence of similar others even with limited or no network information; 4) capture niche dynamics cross-sectionally by calculating the intensity of exploitation from the carrying capacity and the membership rate; and 5) analyze the niche movement longitudinally by estimating the predicted niche movement equations. We illustrate these capabilities of Blaunet with example datasets. [ABSTRACT FROM AUTHOR]

Persuasion is at the core of norm creation, emergence of collective action, and solutions to ‘tragedy of the commons’ problems. In this paper, we show that the directionality of friendship ties affect the extent to which individuals can influence the behavior of each other. Moreover, we find that people are typically poor at perceiving the directionality of their friendship ties and that this can significantly limit their ability to engage in cooperative arrangements. This could lead to failures in establishing compatible norms, acting together, finding compromise solutions, and persuading others to act. We then suggest strategies to overcome this limitation by using two topological characteristics of the perceived friendship network. The findings of this paper have significant consequences for designing interventions that seek to harness social influence for collective action. [ABSTRACT FROM AUTHOR]

Neuroscience research on sex difference is currently a controversial field, frequently accused of purveying a ‘neurosexism’ that functions to naturalise gender inequalities. However, there has been little empirical investigation of how information about neurobiological sex difference is interpreted within wider society. This paper presents a case study that tracks the journey of one high-profile study of neurobiological sex differences from its scientific publication through various layers of the public domain. A content analysis was performed to ascertain how the study was represented in five domains of communication: the original scientific article, a press release, the traditional news media, online reader comments and blog entries. Analysis suggested that scientific research on sex difference offers an opportunity to rehearse abiding cultural understandings of gender. In both scientific and popular contexts, traditional gender stereotypes were projected onto the novel scientific information, which was harnessed to demonstrate the factual truth and normative legitimacy of these beliefs. Though strains of misogyny were evident within the readers’ comments, most discussion of the study took pains to portray the sexes’ unique abilities as equal and ‘complementary’. However, this content often resembled a form of benevolent sexism, in which praise of women’s social-emotional skills compensated for their relegation from more esteemed trait-domains, such as rationality and productivity. The paper suggests that embedding these stereotype patterns in neuroscience may intensify their rhetorical potency by lending them the epistemic authority of science. It argues that the neuroscience of sex difference does not merely reflect, but can actively shape the gender norms of contemporary society. [ABSTRACT FROM AUTHOR]

When scientists report false data, does their writing style reflect their deception? In this study, we investigated the linguistic patterns of fraudulent (N  =  24; 170,008 words) and genuine publications (N  =  25; 189,705 words) first-authored by social psychologist Diederik Stapel. The analysis revealed that Stapel's fraudulent papers contained linguistic changes in science-related discourse dimensions, including more terms pertaining to methods, investigation, and certainty than his genuine papers. His writing style also matched patterns in other deceptive language, including fewer adjectives in fraudulent publications relative to genuine publications. Using differences in language dimensions we were able to classify Stapel's publications with above chance accuracy. Beyond these discourse dimensions, Stapel included fewer co-authors when reporting fake data than genuine data, although other evidentiary claims (e.g., number of references and experiments) did not differ across the two article types. This research supports recent findings that language cues vary systematically with deception, and that deception can be revealed in fraudulent scientific discourse. [ABSTRACT FROM AUTHOR]

The ‘irrational’ preference for fairness has attracted increasing attention. Although previous studies have focused on the effects of spitefulness on the evolution of fairness, they did not consider non-monotonic rejections shown in behavioral experiments. In this paper, we introduce a non-monotonic rejection in an evolutionary model of the Ultimatum Game. We propose strategy intervention to study the evolution of fairness in general structured populations. By sequentially adding five strategies into the competition between a fair strategy and a selfish strategy, we arrive at the following conclusions. First, the evolution of fairness is inhibited by altruism, but it is promoted by spitefulness. Second, the non-monotonic rejection helps fairness overcome selfishness. Particularly for group-structured populations, we analytically investigate how fairness, selfishness, altruism, and spitefulness are affected by population size, mutation, and migration in the competition among seven strategies. Our results may provide important insights into understanding the evolutionary origin of fairness. [ABSTRACT FROM AUTHOR]

This paper reports on a social discounting experiment conducted with university students in South Africa. In line with other social discounting task experiments, participants identify target individuals at different degrees of intimacy in their social network and then make 10 choices involving sums of money for themselves or their targets. For an altruism premium to exist, senders’ donations to recipients should be positive, statistically and economically significant, and independent of relationship closeness. We hypothesize that in addition to the altruism premium for kin documented in the literature, there may be other premia for family in general and for partners and friends. We find that, apart from the “kinship” premium, there is a sizeable “intimacy” premium, which together translates into a substantial “family” premium. The study also finds a “friendship premium”, as is documented in various experiments. The closeness of relationships among family and kin, especially close kin, has a significant and large effect on altruism. The results also attest to the importance of the extended family in regards to the “kinship” premium on altruism. These various premiums on altruism emphasise the importance of the supportive role of various social systems. Nevertheless, altruism within families and among close kin might also be enhanced by building more cohesive and stronger families using developmental social welfare programmes.

Micro-blogging systems have become one of the most important ways for information sharing. Network structure and users’ interactions such as forwarding behaviors have aroused considerable research attention, while mention, as a key feature in micro-blogging platforms which can improve the visibility of a message and direct it to a particular user beyond the underlying social structure, is seldom studied in previous works. In this paper, we empirically study the mention effect in information diffusion, using the dataset from a population-scale social media website. We find that users with high number of followers would receive much more mentions than others. We further investigate the effect of mention in information diffusion by examining the response probability with respect to the number of mentions in a message and observe a saturation at around 5 mentions. Furthermore, we find that the response probability is the highest when a reciprocal followship exists between users, and one is more likely to receive a target user’s response if they have similar social status. To illustrate these findings, we propose the response prediction task and formulate it as a binary classification problem. Extensive evaluation demonstrates the effectiveness of discovered factors. Our results have consequences for the understanding of human dynamics on the social network, and potential implications for viral marketing and public opinion monitoring. [ABSTRACT FROM AUTHOR]

Psychological and other persuasive mechanisms across diverse contexts are well researched, with many studies of the effectiveness of specific persuasive techniques on distinct types of human behaviour. In the present paper, our specific interest lies in the development of a generalized modular psychometric tool to measure individuals’ susceptibility to persuasion. The scale is constructed using items from previously developed and validated particulate scales established in the domains of social psychology and behavioural economics. In the first study we establish the Susceptibility to Persuasion–II (StP-II) scale, containing 54 items, 10 subscales and further 6 sub-sub scales. In Study 2 we establish the scale’s construct validity and reconfirm its reliability. We present a valid and reliable modular psychometric tool that measures general susceptibility to persuasive techniques. Since its inception, we have successfully implemented the StP-II scale to measure susceptibility to persuasion of IT security officers, the role of psychology of persuasion in cybercrime victims and general persuadability levels of Facebook users; these manuscripts are in preparation. We argue that the StP-II scale shows promise in measuring individual differences in susceptibility to persuasion, and is applicable across diverse contexts such as Internet security and cybercrime.

Demonstrability—the extent to which group members can recognize a correct solution to a problem—has a significant effect on group performance. However, the interplay between group size, demonstrability and performance is not well understood. This paper addresses these gaps by studying the joint effect of two factors—the difficulty of solving a problem and the difficulty of verifying the correctness of a solution—on the ability of groups of varying sizes to converge to correct solutions. Our empirical investigations use problem instances from different computational complexity classes, NP-Complete (NPC) and PSPACE-complete (PSC), that exhibit similar solution difficulty but differ in verification difficulty. Our study focuses on nominal groups to isolate the effect of problem complexity on performance. We show that NPC problems have higher demonstrability than PSC problems: participants were significantly more likely to recognize correct and incorrect solutions for NPC problems than for PSC problems. We further show that increasing the group size can actually decrease group performance for some problems of low demonstrability. We analytically derive the boundary that distinguishes these problems from others for which group performance monotonically improves with group size. These findings increase our understanding of the mechanisms that underlie group problem-solving processes, and can inform the design of systems and processes that would better facilitate collective decision-making.

Fish consumption in Mexico is considered low (around 12 kg per person per year) and non-homogeneously distributed across the country. One of the reasons for this situation is the scarcity of wholesale selling sites. In this context, the Mercado del Mar (MM), located in Guadalajara city, Jalisco, is the second biggest wholesale fish market in Mexico, with a distribution of about 500 tons per day and a variety of about 350 different species of fish. In this paper, we argue that MM has accumulated social capital, which is formed from two main resources: buyer and seller relationships, and reputation. Specifically, the MM manages a broad and intensive interaction among business actors and the already achieved reputation allows the MM to adapt to market changes. To validate our hypotheses, an empirical study was conducted in 2015 by means of interviews to fish wholesalers in the MM and a sample of their suppliers and buyers. For simplicity we have only considered fresh water fish. We have followed snow-ball sampling as the survey strategy. Results show that the MM has responded to fish market dynamics organizing a complex network of buyers and suppliers whose relationships can be explained in the form of strong and weak ties. At the same time, reputation has been the central resource to build this social capital and also gives place to market transactions. Additionally, the strategic position of Guadalajara city and the well-connected routes have facilitated fish bulking and distribution in the region. [ABSTRACT FROM AUTHOR]

Finding effective solutions to manage marine resources is high on political and conservation agendas worldwide. This is made more urgent by the rate of increase in the human population and concomitant resource pressures in coastal areas. This paper links empirical socio-economic data about perceptions of marine resource health to the breaking of marine management rules, using fisheries as a case study. The relationship between perceived rule-breaking (non-compliance with regulations controlling fishing) and perceived health of inshore marine environments was investigated through face-to-face interviews with 299 heads of households in three Tanzanian coastal communities in November and December 2011. Awareness of rules controlling fishing activity was high among all respondents. Fishers were able to describe more specific rules controlling fishing practices than non-fishers (t = 3.5, df = 297, p<0.01). Perceived breaking of fishing regulations was reported by nearly half of all respondents, saying “some” (32% of responses) or “most” (15% of responses) people break fishing rules. Ordinal regression modelling revealed a significant linkage (z = −3.44, p<0.001) in the relationship between respondents' perceptions of deteriorating marine health and their perception of increased rule-breaking. In this paper, inferences from an empirical study are used to identify and argue the potential for using perceptions of ecosystem health and level of rule-breaking as a means to guide management measures. When considering different management options (e.g. Marine Protected Areas), policy makers are advised to take account of and utilise likely egoistic or altruistic decision-making factors used by fishers to determine their marine activities.

The local neighborhood forms an integral part of our lives. It provides the context through which social networks are nurtured and the foundation from which a sense of attachment and cohesion with fellow residents can be established. Whereas much of the previous research has examined the role of social and demographic characteristic in relation to the level of neighboring and cohesion, this paper explores whether particular environmental features in the neighborhood affect social porosity. We define social porosity as the degree to which social ties flow over the surface of a neighborhood. The focus of our paper is to examine the extent to which a neighborhood's environmental features impede the level of social porosity present among residents. To do this, we integrate data from the census, topographic databases and a 2010 survey of 4,351 residents from 146 neighborhoods in Australia. The study introduces the concepts of wedges and social holes. The presence of two sources of wedges is measured: rivers and highways. The presence of two sources of social holes is measured: parks and industrial areas. Borrowing from the geography literature, several measures are constructed to capture how these features collectively carve up the physical environment of neighborhoods. We then consider how this influences residents' neighboring behavior, their level of attachment to the neighborhood and their sense of neighborhood cohesion. We find that the distance of a neighborhood to one form of social hole–industrial areas–has a particularly strong negative effect on all three dependent variables. The presence of the other form of social hole–parks–has a weaker negative effect. Neighborhood wedges also impact social interaction. Both the length of a river and the number of highway fragments in a neighborhood has a consistent negative effect on neighboring, attachment and cohesion. [ABSTRACT FROM AUTHOR]

This paper investigates how social influence can alter physiological, psychological, and functional responses to a placebo product and how such responses influence the ultimate endorsement of the product. Participants consumed a product, “AquaCharge Energy Water,” falsely-labeled as containing 200 mg of caffeine but which was actually plain spring water, in one of three conditions: a no social influence condition, a disconfirming social influence condition, and a confirming social influence condition. Results demonstrated that the effect of the product labeling on physiological alertness (systolic blood pressure), psychological alertness (self-reported alertness), functional alertness (cognitive interference), and product endorsement was moderated by social influence: participants experienced more subjective, physiological and functional alertness and stronger product endorsement when they consumed the product in the confirming social influence condition than when they consumed the product in the disconfirming social influence condition. These results suggest that social influence can alter subjective, physiological, and functional responses to a faux product, in this case transforming the effects of plain water.

This paper advances theories of social learning through an empirical examination of how social networks change over time. Social networks are important for learning because they constrain individuals’ access to information about the behaviors and cognitions of other people. Using data on a large social network of mobile device users over a one-month time period, we test three hypotheses: 1) attraction homophily causes individuals to form ties on the basis of attribute similarity, 2) aversion homophily causes individuals to delete existing ties on the basis of attribute dissimilarity, and 3) social influence causes individuals to adopt the attributes of others they share direct ties with. Statistical models offer varied degrees of support for all three hypotheses and show that these mechanisms are more complex than assumed in prior work. Although homophily is normally thought of as a process of attraction, people also avoid relationships with others who are different. These mechanisms have distinct effects on network structure. While social influence does help explain behavior, people tend to follow global trends more than they follow their friends. [ABSTRACT FROM AUTHOR]

Cooperation amongst resource users holds the key to overcoming the social dilemma that characterizes community-based common-pool resource management. But is cooperation alone enough to achieve sustainable resource use? The short answer is no. Developing management strategies in a complex social-ecological environment also requires ecological knowledge and approaches to deal with perceived environmental uncertainty. Recent behavioral experimental research indicates variation in the degree to which a group of users can identify a sustainable exploitation level. In this paper, we identify social-ecological micro-foundations that facilitate cooperative sustainable common-pool resource use. We do so by using an agent-based model (ABM) that is informed by behavioral common-pool resource experiments. In these experiments, groups that cooperate do not necessarily manage the resource sustainably, but also over- or underexploit. By reproducing the patterns of the behavioral experiments in a qualitative way, the ABM represents a social-ecological explanation for the experimental observations. We find that the ecological knowledge of each group member cannot sufficiently explain the relationship between cooperation and sustainable resource use. Instead, the development of a sustainable exploitation level depends on the distribution of ecological knowledge among the group members, their influence on each other’s knowledge, and the environmental uncertainty the individuals perceive. The study provides insights about critical social-ecological micro-foundations underpinning collective action and sustainable resource management. These insights may inform policy-making, but also point to future research needs regarding the mechanisms of social learning, the development of shared management strategies and the interplay of social and ecological uncertainty.

The article presents the author's views on several research papers related to social psychology. The author states that a paper by K. Van den Bos published within the issue has attempted to address many of issues retaled to social psychology and broaden the understanding of threat-compensation processes beyond the scope of other threat-compensation theoretical perspectives. The author states that Van den Bos's intuition to begin with existentialist theory is a good one.

This paper will discuss the role of the jesters at the court of Nasr al-Din Shah, with more particular reference to Karim Shire'i, whose humor gained a lasting place in popular memory. It will look at the jesters in the context of their essential role, to remind the king that he was human. This poses a number of questions with regard to who the jester was and how he carried out his function. First, there is the question of the relationship between the Shah and jester, the degree to which it could become personal and why. Second, the paper will look at the jester's identity and the way it is defined by his relationship with the Shah. Third, it will consider the jester's relationship with the court as a whole and his function within a strictly related hierarchical environment. All of these required that the jester constantly maintain a delicate and sometimes dangerous balance, which could only be carried out by one who inherently possessed a particular kind of wit. Consideration will be given as to what the jester represented both to the court and to the public, specifically with reference to the widely held concept of the wise fool, and its religious implications. This relates to the issue of 'innocence,' ('the mad have cast upon their tongues words from the unseen') whether natural or assumed and its purpose in allowing freedom to the jester to draw the ruler's attention to unpalatable truths. Further points to explore are the relationship between the jester and chaos in an ordered environment and how far the jester pressed the boundaries, or even exerted political influence, and how far his function was in fact conservative and destined to help preserve the existing order. Last, the paper will look at the origins of the court jesters as far as they are known and consider their implications for the rise of these individuals. It will attempt to establish if each was characterized by a particular kind of buffoonery by comparing and contrasting them. In particular, the jokes attributed to Karim Shire'i will be discussed both in terms of how far it is possible to identify him as their author with any certainty and how far they may be considered as constituting a genre of humor. Finally, the legacy of this humor within the popular memory will be assessed. [ABSTRACT FROM AUTHOR]

This paper is a critical response to the newest version of the rational choice theory of religion (RCTR). In comparison with previous critiques, this paper takes aim at RCTR's foundational assumption of psychological egoism and argues that the thesis of psychological egoism is untenable. Without that thesis, the normative aspects of religious commitment cannot be reduced validly to instrumental reason. On neither conceptual nor empirical grounds therefore can religion or religious commitment be defined comprehensively in terms of exchange theory. With the failure of psychological egoism as a point of departure, the paper articulates an alternative theory of religion, one based on the epistemic rationality grounded in religious experience and religious emotion.

Several philosophers have recently claimed to have discovered a new and rather significant problem with virtue ethics. According to them, virtue ethics generates certain expectations about the behavior of human beings which are subject to empirical testing. But when the relevant experimental work is done in social psychology, the results fall remarkably short of meeting those expectations. So, these philosophers think, despite its recent success, virtue ethics has far less to offer to contemporary ethical theory than might have been initially thought. I argue that there are plausible ways in which virtue ethicists can resist arguments based on empirical work in social psychology. In the first three sections of the paper, I reconstruct the line of reasoning being used against virtue ethics by looking at the recent work of Gilbert Harman and John Doris. The remainder of the paper is then devoted both to responding to their challenge as well as to briefly sketching a positive account of character trait possession. [ABSTRACT FROM AUTHOR]

This special issue of the journal "Symbolic Interaction" focuses on theory and method in symbolic interactionism. Quality papers were received from several countries and they have provided theoretical commentary and technical information with which to solve methodological problems. In some cases, the authors of the papers were asked to reduce the length of their articles significantly so that eleven articles were included. These articles have been organized under various issues that are common to all social research but are of special interest to interactionists.

This paper reviews the scope of Basil Bernstein's sociology, indicating some of the research that his ideas have inspired, shaped or provoked. Although it takes a roughly chronological approach to the development of his ideas, the paper emphasizes how consistently he explored the making of societies and social classes, and the structuring of social interaction. The title of the paper reflects how successfully Bernstein met Wright Mills' criterion for a true sociological imagination—that it seeks to grasp the extent to which 'personal troubles' are 'public issues' arising from the changing forms of social inequalities as these are produced from generation to generation.

Recently, increasing numbers of users have adopted microblogging services as their main information source. However, most of them find themselves drowning in the millions of posts produced by other users every day. To cope with this, identifying a set of the most influential people is paramount. Moreover, finding a set of related influential users to expand the coverage of one particular topic is required in real world scenarios. Most of the existing algorithms in this area focus on topology-related methods such as PageRank. These methods mine link structures to find the expected influential rank of users. However, because they ignore the interaction data, these methods turn out to be less effective in social networks. In reality, a variety of topics exist within the information diffusing through the network. Because they have different interests, users play different roles in the diffusion of information related to different topics. As a result, distinguishing influential leaders according to different topics is also worthy of research. In this paper, we propose a multi-topic influence diffusion model (MTID) based on traces acquired from historic information. We decompose the influential scores of users into two parts: the direct influence determined by information propagation along the link structure and indirect influence that extends beyond the restrictions of direct follower relationships. To model the network from a multi-topical viewpoint, we introduce topic pools, each of which represents a particular topic information source. Then, we extract the topic distributions from the traces of tweets, determining the influence propagation probability and content generation probability. In the network, we adopt multiple ground nodes representing topic pools to connect every user through bidirectional links. Based on this multi-topical view of the network, we further introduce the topic-dependent rank (TD-Rank) algorithm to identify the multi-topic influential users. Our algorithm not only effectively overcomes the shortages of PageRank but also effectively produces a measure of topic-related rank. Extensive experiments on a Weibo dataset show that our model is both effective and robust. [ABSTRACT FROM AUTHOR]

In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, population size, geography, mass media, and type of social influence play important roles. In the present paper, we investigate for the first time the impact that institutions have on cultural diversity. In our first three studies, we extend existing agent-based models and explore the effects of institutional influence and agent loyalty. We find that higher institutional influence increases cultural diversity, while individuals' loyalty to their institutions has a small, preserving effect. In three further studies, we test how bottom-up and top-down processes of institutional influence impact our model. We find that bottom-up democratic practices, such as referenda, tend to produce convergence towards homogeneity, while top-down information dissemination practices, such as propaganda, further increase diversity. In our last model—an integration of bottom-up and top-down processes into a feedback loop of information—we find that when democratic processes are rare, the effects of propaganda are amplified, i.e., more diversity emerges; however, when democratic processes are common, they are able to neutralize or reverse this propaganda effect. Importantly, our models allow for control over the full spectrum of diversity, so that a manipulation of our parameters can result in preferred levels of diversity, which will be useful for the study of other factors in the future. We discuss possible mechanisms behind our results, applications, and implications for political and social sciences. [ABSTRACT FROM AUTHOR]

Suburban exploitation of the central city was once a hotly contested issue, but the exodus of people and jobs from the city and the involvement of the federal government in urban service provision have moved it from the forefront of scholarly attention. Those same developments, however argue for more rather than less attention to exploitation, and the purpose of this paper is to offer some of that. Using data collected for 188 relatively comparable American SMS As for 1960, 1970, and 1980, the paper begins with a replication of an earlier study by Kasarda of suburban demands for city service spending. It then extends that research to 1980 and expands it to asses suburban participation in city retail sales generation as well. The results indicate a substantive narrowing over time of suburban demands for city services, but a sizeable and growing gap nonetheless between expenditures demanded and retail revenues provided. The paper than turns to an analysis that attempts to test empirically th relative merits of ecological and politicoeconomic explanation for these changes. The results of that test are more supportive of the former then the latter; hence, the paper concludes with an interpretation of them that links to underlying ecological processes the changing social psychological perspective on the city and its role in social life held by surrounding suburban dwellers.

This paper gives an overview of developments in the area of role theory which took place in West Germany between 1958 and 1980. We differentiate three periods. The first is characterized by a discussion of Dahrendorfs Homo Sociologicus, of which we highlight only the essentials. This discussion took place in the early `60s. For the second period, in the late '60s - early 70s, the role theory discussion went into a different phase as a result of the so-called `positivism debate' in German sociology. The various points of view explored in this discussion seem to have converged since the mid '70s; the contours of an integrated role theory are becoming apparent. The paper closes with an overview of both positive and negative sides of the developments outlined. [ABSTRACT FROM AUTHOR]

This paper argues that the clinical perspective on mental handicap which under- pins most research and professional practice in the field does not help us to explain or understand how mentally handicapped people are valued and treated in their day-to-day dealings with others. Using material gathered in interviews with the parents of mentally handicapped children, the paper plots the unfolding of the idea of subnormality and traces the gradual transition in the child's status as he drifts from normal baby to handicapped infant. It shows how subnormality emerges as a social state, which can be defined in terms of the qualities and capacities which are ascribed to or withheld from mentally handicapped people. In this sense, it is suggested that the social roles allocated to mentally handicapped people are created and shaped from the social meanings imputed to the diagnosis. [ABSTRACT FROM AUTHOR]

Neo-Weberian closure theory developed principally by Parkin appears at first glance to suffer from two opposing weaknesses — that its central concept of exclusion is either too broad or too narrow. This paper demonstrates that these objections are spurious. It then uncovers several real problems which have not yet been examined by the critics of closure theory. These problems have to do with Parkin's conceptions of usurpation, of the withdrawal of services, and of property, as well as with the ambiguity in the politics of Parkin's closure theory. The paper corrects these weaknesses and clarifies this ambiguity and concludes that closure theory so-corrected provides a promising framework for going beyond analyses focused narrowly on one particular means of domination and one particular set of monopolization and exclusion rules to a focus on monopolization and exclusion per se.

Drawing upon insights from the social movement literature as well as leadership experience in a successful social movement organization, this paper suggests aspects of a framework for integrating traditional and contemporary approaches. The case history of JUST (Johnstowners United to Stop another Tragedy) is used to illustrate the interaction of grievances and structures in the career of a social movement organization. In addition to helping fill a lacuna in the literature on the internal dynamics of such organizations, this analysis also demonstrates the importance of the nature of the grievance as well as the target group's structural entrenchment. The paper focuses upon a relatively anomalous case for U.S. social movement organizations: an SMO which was successful despite displacement goals. The final section of the paper includes a summary diagram of the factors involved in JUSTs successful protest effort as well as broader generalizations suggesting the conditions under which grievances or infrastructures are more salient in explaining social movement phenomena.

Using a small set of interlocking definitions, this paper presents a generally applicable conceptualization of social structure developed from recollections of Merton's late-1950s formulation. A brief review of the literature supports the view that the proposed conceptualization provides sociological researchers with a relatively simple and logically consistent overall framework, generally continuous with past theorizing, in which to place their own findings. The paper pays particular attention to how social structures are related causally and epistemologically to more micro-level psychological and more macrolevel sociocultural phenomena. Theoretical considerations and empirical evidence suggest a decrease in the likelihood and speed of change as we move from psychological- to social structural- to sociocultural-level phenomena. Although they require proof in each instance, these postulated differences in the relative speed with which psychological-, social structural-, and sociocultural-level phenomena tend to affect each other provide a new and potentially useful tool for unraveling the knotted causal connections among these different-level phenomena.

This paper argues that organizations with a particular social network structure are more effective than most organizations in responding to crises. Further, it is argued that the effective structure does not occur naturally, but must be designed consciously and carefully. A theory is developed based on well-founded principles of social science, most notably work on formal structure, conflict, friendships, and organizational crises. The paper concludes with an experimental test of one of the four propositions deduced from the theory. Six trials of the experiment found significant support for this proposition.

Human interaction and communication involve space in multiple ways. This paper examines the spatial and interactional order of a covertly video-taped police interrogation. When the participants enter the interrogation room and become engaged in the interrogation process, the room itself is a constraint and a resource for interaction. While interacting within a built environment, the participants appropriate their material surroundings in ways that constitute a spatial order and make possible certain arguments. This paper examines how the physical structure of the interrogation room is differentially appropriated, used, and filled in by the participants‘ territorial and postural manoeuvers over the course of their interaction; and how the spatial structures thus created by the bodily appropriation of the physical locale are subsequently formulated by talk and thereby used as a metaphorical resource to frame the participants‘ situated experience. Through this embedded process, the interrogators move the suspect toward confession. [ABSTRACT FROM AUTHOR]

The article examines concepts of sequence and methods for analyzing sequences. Sequence means an ordered list of elements. In the present paper, the sequence will always be temporal, but mathematically the underlying property is order in one dimension, so spatial sequences would also fall under the term. A number of properties of sequences will be useful in the paper. First, events in a sequence can be unique or they can repeat. Second, sequences can have dependence between their states. Third, there can be varying degrees of dependence between various whole sequences. Fourth, sequence can be investigated either for itself or as an independent or dependent variable. Sequence analysis holds great promise for sociology. Most of classic theories are sequential or interactional theories. What the field needs now are junior scholars committed to exploring what sequence regularities can tell people about social life. The methods will provide researchers with far more effective ways of analyzing life courses, careers, and other such relatively independent and regular sequences, ways of analyzing that accord directly with the canonical theoretical apparatus of the discipline.

Viewing schools of social work and human service agencies as organizations striving to meet certain needs in an attempt to survive in a frequently turbulent, and sometimes hostile environment, this paper utilizes open systems and exchange theory to develop a frame work for analyzing school-agency relationships. The framework is composed of two major areas: (1) a review of the dynamics underlying school-agency relationships, and (2) an evaluation of the intraorganizational, interorganizational, and environmental factors that influence the nature of the relationships between schools qf social work and human service agencies. The paper concludes by presenting an overall strategy for guiding the development of school-agency relationships and discusses the organizational principles that influence its application.

This paper presents the authors' reply to commentaries on their article The Family Realm: Theoretical Contributions for Understanding Its Uniqueness. We believe that life within the family realm is a unique part of the human experience and that having a concept that helps us recognize and articulate this will be a helpful addition to the field. The main purpose of our paper was to demonstrate that when our perspective starts by focusing on familial phenomena we see things differently than when our perspective starts from one of the older disciplines. A family realm perspective helps us realize that some family phenomena are more fundamental than the social and historical factors that influence, shape and mold families. Thus far, we have not entirely ascertained which aspects of the family realm are inherent and which are developed by cultural and social conditions. It is only in the family realm that people are connected through generations. The other characteristics of the family realm that we identify in our essay are relatively unique to this sphere. This means that relationship permanence, concern for the total person, emotionality and so on, exist in nonfamily realms but they are experienced in very differently ways in the family part of life.

This paper tests the theory of cumulative advantage and disadvantage as it applies to the productivity and prestige of academic departments within sociology. The theory suggests that past perceptions of departmental prestige and cumulative records of faculty productivity are of greater significance than more recent levels of productivity in determining their perceived level of eminence within the discipline; a phenomenon due to the accumulation of past performance and recognition over time. The paper employs two widely disseminated measures of departmental eminence: the 1966 Cartter Report rankings and the 1982 Conference Boards assessments. Measures of depart- mental productivity are derived from cumulative publication histories of departments between 1936 and 1989 in three preeminent sociological journals; namely, the American Sociological Review, American Journal of Sociology, and Social Forces. The paper finds that while past accomplishments do not bear importantly on current perceptions of departmental prestige after con- trolling for the level of productivity maintained during the preceding decade, prior perceptions of prestige are strongly associated with current rankings. In addition, past perceptions of academic prestige are found to be highly stable, thereby creating the potential for a stratification hierarchy that allows for little mobility over time.

Many sociologists believe that behavioral sociology is alien to traditional sociological thought, and some have questioned its legitimacy as a sociological perspective. This paper takes the position that behavioral sociology is very much in accord with basic tenets of sociology. The belief that it is not results from misunderstanding and confusion about the foundations and practice of behavioral sociology. Three key concerns about behavioral sociology are addressed: (1) the subject matter of behavioral sociology and its distinction from behavioral psychology; (2) the unexplained "givens" of behavioral sociology (the origins of existing reward systems), and (3) the concern that behaviorists view human behavior as mechanistic and unfeeling. The paper concludes that many differences between behavioral sociology and other sociological perspectives have been exaggerated, that behavioral sociology does exhibit most traditional characteristics of the discipline, and that the concern with the legitimacy of behavioral theory in sociology has obscured the one significant difference that does exist disagreement over the goals and conduct of a science of human behavior.

This paper critically examines available theoretical models which have been derived front statistically established patterns of association between contextual and organizational variables. These models offer an interpretation of organizational structure as a product of organizational structure as a product of primarily economic constraints which contextual variable are impose. It is argued that available models in fact attempt to explain organization at one remove by ignoring the essentially political process, whereby power-holders within organizations decide upon courses of strategic action. This `strategic choice' typically includes not only the establishment of structural forms but also the manipulation of environmental features and the choice of relevant performance standards. A theoretical re-orientation this kind away from functional imperatives and towards' a recognition of political action is developed and illustrated in the man body of the paper.

This paper examines the community situation of shipyard workers on Tyneside, certain aspects of their orientations to work and general social perspectives, and the relationship of these to each other and to the structure of social relations at work. In terms of their community situation shipyard workers would seem to come close to Lockwood's traditional proletarian type of worker. There is evidence to suggest, however, that these workers' social perspectives are not at all clearly traditional proletarian. The explanation for this is found, at least m part, m the much greater complexity of social relations at work than are accounted for in the model of traditional proletarianism. The paper suggests that existing typologies of the orientations and social perspectives of workers need to be refined by more detailed studies of the structural and relational aspects of both work and community situations. The paper concludes with a brief examination of changes in both industry and community and the likely effect of these on the social perspectives of shipbuilding workers. [ABSTRACT FROM AUTHOR]

Considerable attention has been given recently to the perplexing problem of the relationship between attitudes and behavior (Ehrlich, 1969; Deutscher, 1969; Warner and DeFleur, 1969; Ajzen et al., 1970; Lastrucci, 1970; Tarter, 1970). Methodological issues have been debated, the lack of congruence between attitudes and behavior has been examined, and a variety of solutions have been offered. We are told, for example, that the continuing poor correlation between measured attitudes and overt behavior requires us to search for the intervening variable or variables which apparently obtain (Ehrlich, 1969); or to employ the "direct observation" of the phenomenon under investigation rather than try to extrapolate from paper-and-pencil tests to behavior (Deutscher, 1969); or to develop theories that, in turn, enable us to find indicators that are more valid than the paper-and-pencil type (Lastrueci, 1970); or to simply admit that attitudes as "presently conceptualized play no real role in behavior" (Tarter, 1970). A number of important aspects of attitude research, however, have been obscured or omitted in these discussions. For the surprising aspect of the situation is not, as has often been implied, the lack of congruence between attitudes and behavior, but the persistent use of research designs that are inappropriate for the complexity of the subject under investigation. Further, it is surprising that researchers have failed to draw out other important implications of their research. That is, the fact that an attitude does not lead directly to a behavior does not justify the assertion that attitudes play no role in behavior, or that attitude research lacks significant implications for social life. The basis for this latter statement will be shown below in a discussion of the values of attitude research. It may be that inadequate research designs, valued for their simplicity rather than their appropriateness, are a manifestation of the "publish or perish" syndrome. In any ease, this paper attempts to outline the problems and the values of attitude research, and to demonstrate thereby that such research is of great significance for the understanding of social phenomena. If that significance seems minimized by those studies that have found poor correlation between attitudes and behavior, the fault lies both in the failure to create research designs that reflect the complexity of the problem and in the tendency to exalt the importance of the proximate causes of overt behavior.

As the name suggests, social-psychology is a bastard field. It consists of such a variety of peoples doing so many different things in different ways, that it defies definition—at least for me. In spite of the neat delineations which are made in textbooks and the scholarly historical treatments which appear in encyclopediae and symposia, I find it difficult to grasp a concept of "social-psychology" which is anything more than the operational definition: "Social psychology is what people who call themselves social-psychologists, do." That is not much help, but it is all we have got. I mention my own confusion in this matter, not with the aim of confusing others, but by way of explanation: some of the issues I will touch upon in this paper may infringe upon what readers consider to be other areas of sociology. I regret such territorial invasions. But in my own quest for understanding why people act as they do, I have increasingly found that the traditional "fields" in the discipline and the traditional courses in the catalogue do not provide appropriate categories with which I can explain to colleagues and students what it is I am discovering. Having said all of this, let us get down to business. It is a decade since Dennis Wrong published the paper in which he challenged "The oversocialized conception of man in modern society" (1961). Reacting to a determinism which pervaded the social sciences and which seemed to be seeping into popular currency, Wrong asked if man were in fact as constrained by a monolithic culture as we social scientists would have it. A few years later Harold Garfinkel referred more bluntly to the models of men constructed by the various social sciences: he called them "judgmental dopes." The cultural dope and the psychological dope are, respectively, the man in the sociologist's society and the man in the psychologist's society (1967:67-68). [ABSTRACT FROM AUTHOR]
