Purpose This study aims to differentiate two types of relationship exploration – substitute relationship exploration (SRE) and complementary relationship exploration (CRE) – and examine their effects on a distributor’s detection capability in relationship governance with upstream suppliers and innovation capability in services to downstream customers. Design/methodology/approach The authors obtained 176 responses from distributors in the semiconductor industry in China. Structural equation modeling and hierarchical moderated regressions are used to test the hypotheses. Findings CRE increases both detection and innovation capability, whereas SRE reduces detection capability and increases innovation capability. Market uncertainty weakens the effect of detection capability but strengthens that of innovation capability on distributor performance. Research limitations/implications First, to the best of the authors’ knowledge, this study is among the first to differentiate SRE and CRE, thus enriching the relationship marketing literature. Second, drawing on information economics, the authors uncovered the differential effects of SRE and CRE on detection and innovation capabilities. Third, market uncertainty moderates the effects of the two capabilities on distributor performance. Practical implications Distributors should be aware that there are different types of relationship exploration and, for that reason, should explore potential suppliers based on their business needs and firm conditions. The results of this study show that both SRE and CRE are beneficial for distributors’ innovation capability, but SRE reduces their detection capability. Practically, firms need to be aware of the trade-offs associated with different types of relationship exploration. Moreover, when market uncertainty is high, distributors should pay more attention to innovation than to detection capability building. Originality/value This study conceptualizes and differentiates between two forms of relationship exploration. By linking them with distributors’ capability building and performance, the authors provide theoretical and practical implications.

Influencer marketing initiatives require firms to select and incentivize online influencers to engage their followers on social media in an attempt to promote the firms’ offerings. However, limited research considers the costs of influencer marketing when evaluating these campaigns’ effectiveness, particularly from an engagement elasticity perspective. Moreover, it is unclear whether and how marketers could enhance influencer marketing effectiveness by strategically selecting influencers, targeting their followers, or managing content. This study draws on a communication model to examine how factors related to the sender of a message (influencer), the receiver of the message (influencer's followers), and the message itself (influencer's posts) determine influencer marketing effectiveness. The findings show that influencer originality, follower size, and sponsor salience enhance effectiveness, and posts that announce new product launches diminish it. Several tensions arise when firms select influencers and manage content: Influencer activity, follower–brand fit, and post positivity all exert inverted U-shaped moderating effects on influencer marketing effectiveness, suggesting that firms that adopt a balanced approach along these dimensions can achieve greater effectiveness. These novel insights offer important implications for marketers designing influencer marketing campaigns.

PurposeDrawing on expectancy value theory (EVT), this paper examines knowledge exchange between expatriate and host country national (HCN) dyads to understand whether receivers' perceptions about senders' motivation to transfer knowledge and perceived value of the knowledge jointly affect receivers' motivation to learn and, in turn, facilitate their knowledge acquisition and sharing.Design/methodology/approachLatent moderated structural (LMS) equations were used to analyze data from 107 expatriate–HCN dyads working in the Asia Pacific region.FindingsIn general, whether senders are expatriates or HCNs, only when receivers perceive that (1) knowledge to be transferred is valuable and (2) senders are motivated to transfer, receivers are likely to be motivated to receive knowledge transferred from senders and, in turn, acquire and share knowledge with senders.Originality/valueThis study is one of the first in the expatriate and knowledge transfer literature to address the mixed findings between senders' motivation to transfer and receivers' knowledge acquisition and sharing by drawing on EVT.

Whether a focal firm’s network embeddedness is capable of curtailing its partner firm’s opportunism is described as questionable in interfirm relationship literatures. Drawing on theories of business networks and opportunism governance, we examine the distinct effects of the focal firm’s network embeddedness on its partner’s strong and weak form opportunism. We argue that network embeddedness can curtail a partner’s weak form opportunism but cannot deter strong form opportunism due to the substantial benefits obtained from breaking contractual terms and the network’s lack of formal enforceability. Moreover, we draw from institutional theory to explore how network embeddedness, as an external informal institution, interacts with the formalization of the interfirm relationship and the focal firm’s government relations. Survey data on 227 firms’ interfirm relationship experience verify most of our hypotheses. Our findings provide implications regarding the role of network embeddedness and its synergistic effects with formalization and government relations in interfirm relationships.

Robot-assisted Minimally Invasive Surgery (MIS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) are commonly adopted in Gastro-Intestinal (GI) cancer treatment with Endoscopic Submucosal Dissection (ESD). While using fully flexible cable- driven robots brings benefits to patients such as lower rate of complications and shorter healing time, the engineering challenges, for example, size and stiffness, manufacturability and sensorless environment, limit functionalities of robotic instruments and surgery performance. The rolling feature, rotation along the wrist of the instrument, is a good-to-have feature for surgical procedures with orientational and positional requirements such as tractioning and suturing with graspers. In traditional laparoscopy, rolling can be achieved by rotating the long straight rod of the instruments, which is straightforward and effective. However, this is not commonly found in cable-driven endoscopic robotic systems due to mechanical limit for linear-to-rolling motion conversion at distal-end and unmodelled friction resisting torque transmission from proximal-end. Generally, researchers have three approaches to this problem. First, rotate the endoscope or overtube and the instrument together [1] [2]. However, this is not favorable to both surgeon and patient since rotating a twisted endoscope inside a patient’s body requires a large amount of torque and rubbing would create discomfort to the patient. Second, rotate the torque coil or backbone of the instrument [3] [4]. Because friction inside the endoscope is unpredicted and rotation is coupled with roll, pitch, and yaw motion, sophisticated modeling, shape/orientation sensing feedback may be required for robotic automation. Third, develop a distal mechanism to convert cable linear motion into axial rotation [5] [6]. With this method, the coupling problem is solved and power transmission efficiency is improved but a larger and more complicated design is required, and an extra-rigid segment is usually unavoidable. The performance depends greatly on design and implementation. This paper aims to demonstrate a scalable distal joint rotation mechanism for continuum endoscopic robots that can increase instrument dexterity and manipulability to ease the work of surgeons.

Socio-cultural settings and lifestyles of communities in Taenia solium taeniosis/cysticercosis (TSTC) in endemic areas influence significantly the epidemiology of the disease. This study investigated the community perceptions and practices influencing the occurrence and endemicity of TSTC. A cross-sectional survey focusing on pig-keeping households was carried out in three wards of Iringa District Council as a representative of other TSTC endemic areas. Questionnaire and observation checklists were employed for data collection. Eighty-seven (99%) of the 88 surveyed households had pit latrines, and 84(95%) of the households were found using their latrines. These latrines varied from good to a very good quality according to subjective qualitative scores. About 294 (85%) pigs were enclosed and 52(15%) were free roaming. The results indicated poor adherence to routine pig inspection at sales (50% inspection) and less pork inspection at slaughter (50% uninspected). Furthermore, there were no authorized centres for slaughter and sales. Health Officers and farmers were comfortable with the boiling form and home prepared pork (>90%). Health Officers perceived deep-frying and roasting of pork as inappropriate preparation methods. Generally, the social cultural practices and life style in the study area promoted the endemicity of Taenia solium life cycle. A strategy for surveillance on socio-cultural practices in the community is important during planning for TSTC control. This community needs sustainable health education on TSTC diseases control

Suppliers in business-to-business (B2B) markets often directly approach end customers in addition to using third-party distribution channels. This phenomenon, known as supplier encroachment, poses an increasing challenge to the distributor's profitability in the supply chain. However, little research has adopted the distributor's perspective to examine how it can overcome this challenge. This study addresses this gap by adopting the dynamic capability and network embeddedness theory to postulate the critical role of the distributors' customer-driving capability in tackling encroachment. Using survey data from 125 distributor firms in the semiconductor industry, we show that distributors' customer-driving capability significantly improves firm performance and that the impact strengthens when supplier encroachment is high. Moreover, we delineate the positive impacts of supplier relationship exploration, distributor relational embeddedness, and customer service excellence on distributors' customer-driving capability. Interestingly, supplier encroachment weakens the effects of supplier relationship exploration and customer service excellence but strengthens that of distributor relational embeddedness, indicating the importance of leveraging peer relationships under high supplier encroachment.

Enhanced Conversational Recast (ECR) is an input-based grammatical intervention approach developed from research on statistical learning. Recent research reported evidence demonstrating the efficacy of ECR on the learning of grammatically obligatory morphemes in English-speaking preschool children with developmental language disorder (DLD). This single-case experimental design study, which adopted a within-participant design with single baseline and control item, investigated the efficacy of ECR in promoting the learning of aspect markers in four Cantonese-speaking typically-developing preschool children. Two children demonstrated positive outcomes with the progressive aspect marker ‘ gan2’ given 12 ECR training sessions within a mean dosage of 288. One of these children demonstrated statistically significant gains in the percentage of correct use in the probes. The lack of positive outcomes in the other two children on the earlier developing aspect marker ‘ zo2’ and limitations of the study were discussed. With early evidence established in the typically developing children in this study, future research on Cantonese speaking children with DLD can be considered.

Background Porcine cysticercosis is endemic in Tanzania, especially in the southern, central part and northern highlands of the country. The disease reduces meat quality and affects pig industry. This study investigated porcine cysticercosis prevalence and possible risk factors for reference in preparation for sustainable control measures. Methods Current seroprevalence and potential risk factors were studied in selected ward/villages of Iringa district council, in the southern highland of Tanzania, prior to a digital health education intervention. A total of 346 pigs from 88 households of Izazi, Migoli and Mlowa wards were studied using an enzyme-linked immunosorbent assay (ELISA), which detects Taenia species antigens (Ag) in sera. Questionnaire used to dig information on pig management and sanitation and hygiene practices. Results The AgELISA detected 22.3% of the surveyed pigs as positive for porcine cysticercosis. The detected porcine cysticercosis seropositivity ranged between 21.3% and 25.7% per individual ward, with at least one seropositive pig in 53.4% of the surveyed households. Confining pigs was significantly related to low porcine cysticercosis seropositivity (OR = 2.426; 95% CI = 1.202–5.300; p = 0.026), whereas scavenging pigs had two times chance of being Ag-ELISA seropositive. Conclusions Pig confinement and feeding skills and community sensitization on hygiene and sanitation are recommended. Therefore, practical ways of delivering health education to rural communities such as the studied community should be investigated.

This study responds to the call for the “internationalization of sales research” by collecting data from 160 international buyers spanning 33 countries and regions. Based on survey data, archival sales records and cultural-distance indices, this research examines the performance-enhancing effect of sales rep-owned commitment as well as its antecedents under varying degrees of cultural distance. Our results show a strong and direct impact of rep-owned commitment, independent of the effect of firm-owned commitment, on enhancing performance indicators including sales volume, importers' purchase share, and importers' future purchase intentions. Moreover, we find two important antecedents to rep-owned commitment: benevolence trust and capability trust. Interestingly, cultural distance moderates the effects of benevolence and capability trust on rep-owned commitment: the larger the cultural distance, the stronger the effect of benevolence trust but the weaker the effect of capability trust. We conclude with theoretical and managerial implications to international marketing research and practice.

There has long been interest in how leaders influence the unethical behavior of those who they lead. However, research in this area has tended to focus on leaders' direct influence over subordinate behavior, such as through role modeling or eliciting positive social exchange. We extend this research by examining how ethical leaders affect how employees construe morally problematic decisions, ultimately influencing their behavior. Across four studies, diverse in methods (lab and field) and national context (the United States and China), we find that ethical leadership decreases employees' propensity to morally disengage, with ultimate effects on employees' unethical decisions and deviant behavior. Further, employee moral identity moderates this mediated effect. However, the form of this moderation is not consistent. In Studies 2 and 4, we find that ethical leaders have the largest positive influence over individuals with a weak moral identity (providing a "saving grace"), whereas in Study 3, we find that ethical leaders have the largest positive influence over individuals with a strong moral identity (catalyzing a "virtuous synergy"). We use these findings to speculate about when ethical leaders might function as a "saving grace" versus a "virtuous synergy." Together, our results suggest that employee misconduct stems from a complex interaction between employees, their leaders, and the context in which this relationship takes place, specifically via leaders' influence over employees' moral cognition.

Background Health workers have traditionally delivered health promotion and education to rural communities in the Global South in paper leaflet formats or orally. With the rise of digital technologies, health promotion and education can be provided in innovative and more effective formats, which are believed to have a higher impact on disease prevention and treatment. Objective The aim of this tutorial is to illustrate how a multi- and interdisciplinary approach can be applied in the design process of digital health messages for use in the Global South. Methods The multi- and interdisciplinary team of the Non-discriminating access for Digital Inclusion (DigI) project digitalized and customized available government-approved paper-based health promotion messages into a screen-suitable format. The team worked closely together and used its diverse expertise to develop digital health messages with disease-specific content in Tanzania’s national language (Swahili) as well as English. The development process included the following phases: a local needs assessment; identification of government-approved health promotion materials in a nondigital format; identification of key health messages; creation of a practical and engaging story, easy to understand for the general public; drafting of a storyboard for an animated video with review, feedback, and revisions; forward and backward translation; audio recording of the story in both languages; finalization and presentation of the animations; development of relevant questions related to the health messages in each domain; and development of web and mobile apps to access the digital health messages. Results Between 2017 and 2019, we developed key health messages, quizzes, and animated health videos to address HIV/AIDS, tuberculosis, Taenia solium cysticercosis and taeniasis, and anthrax, all of which are of public health importance in Tanzania. Feedback from local stakeholders and test users was included in various phases of the process. The 4 videos and other content are available in local information spots on a digital health platform (DigI platform), established by the DigI project, in both Tanzanian Swahili and English. Conclusions Our methodological multi- and interdisciplinary approach ensures that the digital health messages for the public are clear, high quality, and align with the government’s objectives for health promotion. It also demonstrates the diversity of scientific disciplines required when collaborating on a digital health project. We recommend this approach to be applied to the development of other digital health messages for a wide range of diseases. International Registered Report Identifier (IRRID) RR2-10.2196/25128

The hospitality industry is under threat from COVID-19 and the possibility of future crises remains very real. To improve understanding of how such a crisis impacts the attractiveness of pursuing a career in the hospitality industry, this study examines the effects of negative emotions invoked by COVID-19 on hospitality management students’ occupational attitudes. Using a sample of 425 students, we find that in addition to diminishing their occupational identification and in turn, job choice intentions, that the effects of these negative emotions are channeled through three salient motivational pathways, namely self-efficacy, intrinsic and extrinsic motivation, and passion. Thus, the study not only advances theory by providing a more nuanced conceptualization of the effects of negative emotions on occupational attitudes but it identifies important leverage points that can be harnessed to help mitigate the harmful emotional effects of a crisis, such as COVID-19, important and timely contributions that the authors hope will benefit aspiring hospitality industry talent and help restore the attractiveness of careers in the hospitality industry. Future research directions and implications to theory and practice are discussed.

Located in coastal area of Benin, Nokoué Lake is the biggest lake in the West Africa due to his large surface (120 km2) and fishiness productivities. Unfortunately, it is faced with a lot of challenges due to traditional practice of fishing called "Acadja" and the management of every kind of waste. The objective of this study was to show Acadja's influence on the physico chemical quality of the water in Nokoué Lake, and even on the future of the ecosystem and all associated activities. Three sampling taken from Acadja side and also three sampling taken from no Acadja side during dry season have been tested in temperature, pH, dissolved oxygen, suspended solids, turbidity, level in NO3 and NO2--, weight and length of fish. The analysis was made by spectrophotometer DR/2000 Hach, multipara meter wtw 340 and atomic absorption spectrophotometry for Toxic metals (lead). The result revealed that traditional system of fishing called Acadja influences almost of the physico chemical parameters of the water and the fauna aquatic around the Acadja area. Therefore, this practice will threaten and disrupt food security of the habitants by reducing fish productivity. The sensitization sessions are required to lead local people to adhere to sustainable resource management.Keywords: traditional fishing, water pollution, aquatic ecosystem, fish productivity.

Cancer is one of the most striking diseases that has a potential impact on human health with high mortality rate. During the last century many anticancer agents have emerged but unfortunately, these agents could not provide effective solutions for cancer treatment due to side effects and resistance. All over the world, asking for new anticancer agents is still a major goal for medicinal chemists. Pyrrole and pyrrolo[2,3-d]pyrimidine scaffolds are very interesting bioactive core exhibiting several biological activities as anticancer, anti-inflammatory, antimicrobial activities. Herein, we highlighted on the anticancer activity of the pyrrole and pyrrolo[2,3-d]pyrimidine derivatives which are reported to possess anticancer activity and many of them are in market or still in clinical trials. This work deals with design and synthesis of new pyrrole and pyrrolopyrimidine derivatives. The new compounds were screened for their cytotoxic activity against HepG2 and MCF7in vitro. The most active compounds were evaluated for their VEGFR-2 inhibition in vitro

Drawing from the contract learning literature and studies on managing exchange disruptions, this study examines how contracts can be adjusted ex post an exchange disruption to renew interfirm relationships. A multiple-informant survey approach is adopted in this study. Two types of senior managers in 272 manufacturing firms in China (a total of 544 senior managers) are interviewed regarding the resolution process and outcome of exchange disruptions. We find that ex ante contract detail fosters ex post contract adjustments, and contract adjustment has an inverted-U-shaped relationship with relationship continuity in the aftermath of exchange disruptions. Furthermore, the findings show that the relationship between contract adjustment and relationship continuity is moderated by the interdependence structure (buyer dependence advantage and joint dependence) of an interfirm relationship.

The unparalleled growth in multinational corporations in recent decades has witnessed a commensurate rise in the deployment of expatriates to foreign subsidiaries and their subsequent repatriation. However, despite considerable progress in our understanding of the expatriation phase of international assignments, the literature on repatriation remains fragmented and incomplete. Plagued with problematic re-adjustments, high turnover rates, and a range of other obstacles, there is an urgent need for an improved understanding of repatriation. This study systematically reviews the repatriation literature over the previous four decades, identifies its major themes, gaps and limitations, and provides a framework that consolidates the literature and prompts future work in several important new directions.

Background Initial propranolol recommendations for infantile hemangioma published in 2013 were intended as provisional best practices to be updated as evidence-based data emerged. Methods A retrospective multicenter study was performed to evaluate utility of prolonged monitoring after first propranolol dose and escalation(s). Inclusion criteria included diagnosis of hemangioma requiring propranolol of greater than or equal to 0.3 mg/kg per dose, younger than 2 years, and heart rate monitoring for greater than or equal to 1 hour. Data collected included demographics, dose, vital signs, and adverse events. Results A total of 783 subjects met inclusion criteria; median age at initiation was 112 days. None of the 1148 episodes of prolonged monitoring warranted immediate intervention or drug discontinuation. No symptomatic bradycardia or hypotension occurred during monitoring. Mean heart rate change from baseline to 1 hour was –8.19/min (±15.54/min) and baseline to 2 hours was –9.24/min (±15.84/min). Three preterm subjects had dose adjustments because of prescriber concerns about asymptomatic vital sign changes. No significant difference existed in pretreatment heart rate or in heart rate change between individuals with later adverse events during treatment and those without. Conclusion Prolonged monitoring for initiation and escalation of oral propranolol rarely changed management and did not predict future adverse events. Few serious adverse events occurred during therapy; none were cardiovascular.

Drawing on the resource- and competency-based view, this paper examines the relationship between high-performance human resource (HR) practices and firm performance. Using a sample of 189 firms in mainland China, a positive relationship between high-performance HR practices and firm performance was found that was partially mediated by employees’ competencies. We also found the organisational climate for creativity to strengthen such relationship. The implications and future directions of these findings are discussed. Refereed/Peer-reviewed

Drawing on Denison and Mishra (1995)’s framework of organizational culture, this study examines why and when organizational culture is related to knowledge workers’ affective commitment. Data were collected from 640 employees working in three high-technology companies in China. The findings indicate that the relationship between organizational culture and affective commitment is mediated by perceived psychological contract fulfilment. In addition, organizational tenure moderates the relationship between two external dimensions (i.e. adaptability and mission) of organizational culture and perceived psychological contract fulfilment. This study extends the current theoretical framework of organizational culture by demonstrating the underlying mechanism and the boundary condition of the relationship between organizational culture and affective commitment. The findings also provide practical implications for international managers to design appropriate human resource management policies and practices in China. Refereed/Peer-reviewed

This study integrated the Job Demands-Resources (JD-R) model and concept of psychological contract fulfillment into a social exchange theory process framework to improve our understanding how and when job characteristics interact to influence job outcomes. Using survey data (n=334), we found evidence to support our hypothesized relationships between job characteristics (job demands and job resources) and job outcomes (job satisfaction and organizational commitment); and the mediating role of psychological contract fulfillment (transactional and relational), such that when job resources (job control and support) were high, the negative effects of high job demands on psychological contract fulfillment were attenuated. Theoretical and managerial implications are discussed. Refereed/Peer-reviewed

The number of teaching assistants (TAs) working in mainstream schools has soared in recent years as students with special educational needs (SEN) are integrated into regular classrooms. However, research on TAs is rare. This study investigated whether and how work engagement mediates the relationship between self-efficacy and job satisfaction among 292 Chinese TAs working in Hong Kong mainstream schools. Survey data were analyzed using partial least squares structural equation modeling (PLS-SEM). Supported by the social cognitive theory of self-efficacy and self-determination theory of work engagement, our results showed that TAs’ self-efficacy is positively related to their job satisfaction through the mediation of work engagement. Implications for an appropriate focus on enhancing TAs’ self-efficacy through classroom experiences and training courses are discussed.

This study identifies exploratory and exploitative OFDI as two distinct approaches for emerging market (EM) firms to overcome their liability of foreignness in overseas markets. It assesses the performance impacts of both types of OFDI through investigating three sets of questions. (1) What are the differential impacts of exploratory and exploitative OFDI, and how long do they persist? (2) How do industry factors in the home country, including technological turbulence and competitive intensity, moderate these effects? And (3) how can firms balance these two types of OFDI across time? Based on multi-sourced data of 766 Chinese firms during 2008–2015, the results show that both types of OFDI promote performance, yet the positive effect of exploratory OFDI lasts longer than that of exploitative OFDI. Moreover, technological turbulence strengthens the effect of exploratory OFDI and weakens that of exploitative OFDI, but competitive intensity strengthens the effect of exploitative OFDI only. Finally, sequential ambidexterity improves firm performance through exploratory‒exploitative OFDI process.

We present and test a self-consistency theory framework for gossip: that perceived negative workplace gossip influences our self-perceptions and, in turn, this influences our behaviors. Using supervisor-subordinate dyadic time-lagged data (n = 403), we demonstrated that perceived negative workplace gossip adversely influenced target employees’ organization-based self-esteem, which, in turn, influenced their citizenship behavior directed at the organization and at its members. Moreover, by integrating victimization theory into our framework, we further demonstrated that negative affectivity, an individual’s dispositional tendency, not only moderated the self-consistency process but also predicted perceived negative workplace gossip. Our study therefore shifts attention to the target of negative workplace gossip and in doing so offers a promising new direction for future research. Implications to theory and practice are discussed. Refereed/Peer-reviewed

E-cadherin (CDH1) is a putative tumor suppressor gene implicated in breast carcinogenesis. Yet, whether risk factors or survival differ by E-cadherin tumor expression is unclear. We evaluated E-cadherin tumor immunohistochemistry expression using tissue microarrays of 5,933 female invasive breast cancers from 12 studies from the Breast Cancer Consortium. H-scores were calculated and case-case odds ratios (OR) and 95% confidence intervals (CIs) were estimated using logistic regression. Survival analyses were performed using Cox regression models. All analyses were stratified by estrogen receptor (ER) status and histologic subtype. E-cadherin low cases (N = 1191, 20%) were more frequently of lobular histology, low grade, >2 cm, and HER2-negative. Loss of E-cadherin expression (score

Drawing on social capital and agency theories and using a multi-study research design, this study examined how perceived risk and return interacts with familism to influence individuals’ investment strategies in new venture financing, both capital seeking and capital providing behavior. We found that individuals high in familism are more likely to seek capital from and provide capital to family members than non-family members for new ventures. However, such relationships are more complex than prior research suggests because when individuals’ risk and return perceptions are included these interact with familism to differentially influence capital financing behavior directed at family versus non-family members. Contributions to theory and potential avenues for future research are discussed.

We evaluate the use of the magnetotelluric (MT) method to locate crystalline basement and overlying carbonate reservoir rocks underneath a thick overburden in the Sao Francisco basin in Brazil. Mapping the complex basement and the carbonate reservoir using seismic reflection is a major problem in hydrocarbon exploration in this intracratonic basin, and it is expected that MT will provide useful complementary information. In the present study, we analysed 31 MT soundings along four survey lines in the central region of the basin. The MT soundings covered a period range of 0.001–100 s, probing the subsurface resistivity structure down to a maximum depth of about 15 km. The MT data were inverted using a regularized two-dimensional (2D) inversion algorithm with a variety of a priori data for comparison. For model appraisal, we analysed well log (gamma ray, deep resistivity and neutron porosity) data as well as seismic, gravity and magnetic profiles coincident with one MT line passing through the well. We found that shallow geological boundaries separating zones of strong resistivity contrasts also coincide with seismic boundaries in the inversion models with or without a priori data. Using gravity data, it was also possible to define the compartmentalized basement in this sector of Sao Francisco Basin, not clear in the seismic section. However, only by integrating all available information were we able to map the Lagoa do Jacare and Sete Lagoas carbonate member-formations of the Bambui Group, which are considered to host both the source and reservoir rocks identified from past exploratory history of this basin. We also imaged a basement structural high with thinned or disrupted conductive cover rocks over a known zone of hydrocarbon microseepage and a buried conductive (source rock?) channel at its NW margin, the trace of which coincides with the present-day River Paracatu along which gas bubbles have been observed. This suggests that MT may be fruitfully integrated with gravity, magnetic and seismic data to study the structural controls on hydrocarbon occurrence in this basin.

How do firms learn from their alliance partners? Do alliance learning outcomes vary among different types of alliances? Are the learning differentials contingent upon contextual factors in an emerging economy? To address these important questions, this study empirically delineates the nature of explorative and exploitative alliances, examines how they affect product and process innovations, and investigates how such effects vary in different contexts. Using a sample of 220 Chinese firms in the glass industry, we use the structural equation modeling procedure to analyze the data. We find that explorative alliances have a stronger impact on both product and process innovations than do exploitative alliances, product, and process innovations are positively related to both market and efficiency performance, and environmental turbulence enhances the impact of product and process innovations. Our findings provide implications for choosing between explorative and exploitative alliances in line with alliance objectives and firms’ resources, and environmental contexts.

The transfer and diffusion of human resources management (HRM) practices within the geographically dispersed operations of multinational corporations (MNCs) is receiving heightened attention, in particular because it is believed to significantly influence the performance and competitiveness of MNCs and their subsidiaries. However, as a review of the current body of literature suggests, further work is needed if we are to more fully understand the underlying process through which HRM practices are transferred and diffused or provide more holistic guidance with practitioner relevance. In this article, the authors review and synthesize the extant literature on the transfer and diffusion of HRM practices in the MNC context. Five salient themes or questions that prior research attempts to address are identified and critiqued. A general guiding framework is proposed as are possible avenues for future research.

BACKGROUND Determining the effectiveness of a product in repelling mosquitoes or other flying insects is a difficult task. One approach is to use a bioassay with textile fabric. We investigated the role of the textile substrate in a bioassay with a numerical model, and compared the outcome with known results for DEET. The model was then used to determine the effectiveness of textile slow-release formulations based on coatings, and results were compared with those of a field study in the Cameroon. Slow-release formulations are difficult to evaluate with standard tests, as the compound needs a build-up time not present in these tests. RESULTS We found excellent correspondence between the model and the known DEET results without matching parameters. Slow-release approaches are deemed possible but have several drawbacks. Modelling can help in identifying optimal use conditions. The field test with a slow-release system performed better than anticipated by the model, with initially more than 90% repellency. DEET-coated textile was considered not to be marketable, however. CONCLUSION We advise that bioassays characterise in more detail the type of textile fabric used so as to allow conclusions to be drawn by textile modelling. As regards coated-textile slow-release systems, more research is needed. We nevertheless advise usage mainly at entry points, e.g. as scrims. © 2014 Society of Chemical Industry
