Stereotype-threat theory holds that activation of a negative stereotype has a harmful effect on performance in cognitive and motor domains. This paper provides a literature review of stereotype-threat research in the motor domain followed by recommendations for sport psychology practitioners. The review discusses the most widespread stereotypes that exist in sport, the effects of stereotype activation on performance in different sports, and mechanisms that explain why stereotype threat decreases performance. Recommendations for practitioners include individual- and organizational-level approaches, with the former subdivided into interventions aimed at prevention or coping. [ABSTRACT FROM AUTHOR]

Around the world, humans are living longer and politicians are getting older. But what do voters think about politicians of advanced age? We conduct a meta-analysis of 16 conjoint design-based candidate-choice experiments in seven democracies, revealing that older hypothetical candidates are consistently less likely to be favored by respondents—whether compared to the youngest alternative or the second-oldest alternative. We then report the findings of a novel conjoint experiment on Japanese voters designed to elicit whether the milestone of entering a new decade of age (70 vs. 69 years) affects respondents' preferences for hypothetical candidates. Although at most 730 days separate candidates of these ages (limiting concerns of substantial differences in health or fitness), we find a significant penalty for the older candidate. Together, our findings highlight the mismatch between voters' preferences for younger politicians and the ostensible gerontocracy that governs much of the world. [ABSTRACT FROM AUTHOR]

Does war enhance or impede the long-term community-level development of social capital? While wartime mobilization and collective-action efforts might strengthen social ties, extreme destruction can potentially erase these effects. We use historical aerial photographs taken after the indiscriminate firebombing of Tokyo during World War II to measure conditionally independent microvariation in neighborhood-level damage and investigate the relationship between the amount of damage sustained and the present-day strength of neighborhood associations, a key indicator of geographically rooted social capital. Even after decades of population recovery, economic growth, and transformations of the urban space, the most heavily damaged neighborhoods continue to have less organized neighborhood associations and also exhibit lower socioeconomic well-being in terms of education, occupation, and residential stability. These findings are consistent with the idea that the social capital of survivors is a crucial ingredient for postwar recovery: when fewer survivors remain, communities can potentially be set on a path of persistent disadvantage.

The robustness of motor outputs to muscle dysfunction has been investigated using musculoskeletal modeling, but with conflicting results owing to differences in model complexity and motor tasks. Our objective was to systematically study how the number of kinematic degrees of freedom, and the number of independent muscle actuators alter the robustness of motor output to muscle dysfunction. We took a detailed musculoskeletal model of the human leg and systematically varied the model complexity to create six models with either 3 or 7 kinematic degrees of freedom and either 14, 26, or 43 muscle actuators. We tested the redundancy of each model by quantifying the reduction in sagittal plane feasible force set area when a single muscle was removed. The robustness of feasible force set area to the loss of any single muscle, i.e. general single muscle loss increased with the number of independent muscles and decreased with the number of kinematic degrees of freedom, with the robust area varying from 1% and 52% of the intact feasible force set area. The maximum sensitivity of the feasible force set to the loss of any single muscle varied from 75% to 26% of the intact feasible force set area as the number of muscles increased. Additionally, the ranges of feasible muscle activation for maximum force production were largely unconstrained in many cases, indicating ample musculoskeletal redundancy even for maximal forces. We propose that ratio of muscles to kinematic degrees of freedom can be used as a rule of thumb for estimating musculoskeletal redundancy in both simulated and real biomechanical systems.

A handful of recent studies have investigated the causal effect of incumbency on dynasty formation in candidate-centered electoral contexts. We use candidate-level data and a regression discontinuity design to estimate the incumbency advantage and its relation to dynasty formation in the party-centered, closed-list, proportional-representation setting of Norway. The results indicate that the incumbency advantage exists even in this party-centered environment; however, in contrast to recent findings for the United States and the Philippines, we find no evidence that incumbency is important to the formation of dynasties. This finding underscores the need for more research into the role of internal party organizational networks in the perpetuation of political dynasties. [ABSTRACT FROM AUTHOR]

Since gaining full independence in 1905, Norway has experienced more than a century of democratic elections, and has reformed its electoral system three times, most notably with the switch from a two-round runoff system to proportional representation in 1919. This research note introduces a new dataset featuring all candidates running for parliamentary (Storting) elections from 1906 to 2013, and documents the patterns over time and across electoral systems in the development of the party system; candidates’ gender, age, occupation, and geographic ties; and voter turnout. Scholars interested in using the dataset can gain access to it through the Norwegian Centre for Research Data. [ABSTRACT FROM PUBLISHER]

We investigate whether politicians whose family relatives previously served in parliament and cabinet enjoy a competitive 'legacy advantage' in progressing from the backbenches to cabinet. This advantage may stem from two potential mechanisms: a direct effect attributable to the informational advantages of legacies or an indirect effect that operates through greater electoral strength. We evaluate the relative contribution of each mechanism using candidate-level data from Irish parliamentary elections and cabinets from 1944 to 2016. Our results reveal that politicians with a family history in cabinet do enjoy an advantage in cabinet selection, and that this advantage cannot be attributed simply to greater electoral popularity.

The purpose of this study was to examine the association between esport participation and loneliness, as well as its moderating factors. Chinese college students (N = 216) self-reported their esport playing time and degree of loneliness each day immediately before bedtime for four consecutive weeks. The findings revealed that as playing time increased, students did not experience reduced sense of loneliness during playing esport, but they experienced a temporary and intensified feeling of loneliness the same day following gameplay. Students with higher general loneliness tended to feel more after-game loneliness associated with increased esport participation. Students with higher obsessive passion about esport tended to experience more loneliness (both in-game and after-game) associated with increased esport participation. Students with greater coping motivation about esport tended to experience more in-game loneliness associated with previous increased esport participation. Students who played esport less often with friends in person, or with more escape motivation toward esport, tended to increase esport participation time more following previous increased after-game loneliness. The findings suggested that college students should avoid utilizing esport to achieve a sense of belonging and should be cautious of the loneliness-inducing effect after gameplay. A healthy level of loneliness can be maintained by playing esport more with friends in person, learning strategies to avoid obsessive passion, coping motivation, and escape motivation towards esport. • Increased esport participation did not predict a reduction in feelings of loneliness during gameplay. • Increased esport participation predicted heightened feelings of loneliness on the same day following gameplay. • The relationship between esport participation and loneliness was moderated by esport playing habits, passion orientation, and motivation.

In sport and exercise research, examining both within- and between-individual variation is crucial. The ability to investigate change both within competitive events and across a competitive season is a priority for many sport researchers. The aim of this article is to demonstrate an approach to analyzing intensive longitudinal data collected through time-scale-dependent longitudinal designs. Following didactic presentation of the approach, two illustrations from secondary data analysis are used to describe the modeling process in detail. Illustration 1 includes affective response data from an exercise intervention randomized pilot study. Illustration 2 uses referee and player distance data collected during professional soccer games in the English Premier League. Each illustration describes a process for testing and comparing multiple time scale models based on the three-level multilevel model, and results are interpreted. In the discussion, advantages and limitations of the approach are highlighted. [ABSTRACT FROM PUBLISHER]

The method of candidate selection used by parties can influence a number of outcomes related to party organization and representation. In the past decade, Japan’s political parties have increasingly experimented with an ‘open recruitment’ system for selecting new candidates for national elections, but the degree of centralization in the process varies by party. We use candidate and voter survey data to assess whether the new system of recruitment has resulted in intraparty differences in the policy positions of candidates, and their distance from party supporters and the median voter. We find evidence that the new candidate selection method has resulted in the nomination of more centrist and urban-inclined candidates, an indication of greater responsiveness to voters, and that they exhibit higher levels of policy cohesion than their counterparts selected through traditional methods. However, these differences depend on the degree of party centralization in the process. [ABSTRACT FROM AUTHOR]

The purpose of this study was to provide a systematic review of action anticipation studies using functional neuroimaging or brain stimulation during a sport-specific anticipation task. A total of 15 studies from 2008 to 2014 were evaluated and are reported in four sections: expert-novice samples, action anticipation tasks, neuroimaging and stimulation techniques, and key findings. Investigators examined a wide range of action anticipation scenarios specific to eight different sports and utilized functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), and transcranial magnetic stimulation (TMS). Expert-novice comparisons were commonly used to investigate differences in action anticipation performance and neurophysiology. Experts tended to outperform novices, and an extensive array of brain structures were reported to be involved differently for experts and novices during action anticipation. However, these neurophysiological findings were generally inconsistent across the studies reviewed. The discussion focuses on strengths and four key limitations. The conclusion posits remaining questions and recommendations for future research. [ABSTRACT FROM AUTHOR]

Studies of voting behavior in some settings may be hampered by poor data availability or unsuitably large units of aggregation for reported turnout. We propose and demonstrate a practical big-data solution to these kinds of challenges, using fine-grained cell-phone mobility data on millions of GPS locations for more than 300,000 eligible voters in Tokyo. Our approach uses the geolocations of polling stations, combined with GPS data points recorded on election day and a reference day, to measure patterns in individual-level (but anonymized) voting behavior. We first test the validity of the measure by comparing it to official aggregated data on turnout, and then illustrate its substantive utility with an application exploring the well-known relationship between turnout decisions and the cost of voting, proxied by the distance between a voter’s residence and the polling station. Finally, we discuss the potential limitations of the approach and provide step-by-step instructions for other researchers. [ABSTRACT FROM AUTHOR]

Throughout history and across countries, women appear more likely than men to enter politics on the heels of a close family relative or spouse. To explain this dynastic bias in women's representation, we introduce a theory that integrates political selection decisions with informational inequalities across social groups. Candidates with dynastic ties benefit from the established reputations of their predecessors, but these signals of quality are more important to political newcomers such as women. Legislator-level data from twelve democracies and candidate-level data from Ireland and Sweden support the idea that dynastic ties are differentially more helpful to women, and that the quality of predecessors may be more relevant for the entry and evaluation of female successors than their male counterparts. The role of informational inequalities is also reflected in the declining dynastic bias over time (as more women enter politics), and in the differential effect of a gender quota across Swedish municipalities.

A prominent line of theories holds that proportional representation (PR) was introduced in many European democracies by a fragmented bloc of conservative parties seeking to preserve their legislative seat shares after franchise extension and industrialization increased the vote base of socialist parties. In contrast to this "seat-maximization" account, we focus on how PR affected party leaders' control over nominations, thereby enabling them to discipline their followers and build more cohesive parties. We explore this "party-building" account in the case of Norway, using roll call data from six reform proposals in 1919. We show that leaders were more likely to vote in favor of PR than rank-and-file members, even controlling for the parties' expected seat payoffs and the district-level socialist electoral threat facing individual legislators. Moreover, using within-legislator variation, we show that the internal cohesion of parties increased significantly after the introduction of PR. [ABSTRACT FROM AUTHOR]

A substantial body of research examines whether increasing the proportionality of an electoral system increases turnout, mostly based on cross-national comparisons. In this study, we offer two main contributions to the previous literature. First, we show that moving from a single-member district system to proportional representation in multimember districts should, according to recent theories of elite mobilization, produce a contraction in the distribution of mobilizational effort across districts and, hence, a contraction in the distribution of turnout rates. Second, we exploit a withincountry panel data set based on stable subnational geographic units before and after Norway's historic 1919 electoral reform in order to test various implications stemming from the contraction hypothesis. We find significant support for the predictions of the elite mobilization models. [ABSTRACT FROM AUTHOR]
