Based on expectancy theory and social psychology perspectives, this study looks at the differential effects of men and women entrepreneurs’ human capital and networking on their growth expectancies in the context of a transitional economy. Survey data from men and women new venture owners in Bulgaria (n = 544) suggest that growth expectancy among men is significantly and positively associated with outside advice achieved through networking. Among women entrepreneurs, growth expectancy is significantly and positively associated with perceived benefits from prior experience. A Chow test for coefficient differences reveals that the determinants of growth expectancy for women entrepreneurs are significantly different than those for men, rendering support for perspectives from social psychology, which suggest that women have different socialization experiences and, as a result, conceive of their new venture growth differently. Implications for managerial practice and public policy are discussed.

The low-FODMAP diet is a new dietary therapy for the management of irritable bowel syndrome that is gaining in popularity around the world. Developing the low-FODMAP diet required not only extensive food composition data but also the establishment of "cutoff values" to classify foods as low-FODMAP. These cutoff values relate to each particular FODMAP present in a food, including oligosaccharides (fructans and galacto-oligosaccharides), sugar polyols (mannitol and sorbitol), lactose, and fructose in excess of glucose. Cutoff values were derived by considering the FODMAP levels in typical serving sizes of foods that commonly trigger symptoms in individuals with irritable bowel syndrome, as well as foods that were generally well tolerated. The reliability of these FODMAP cutoff values has been tested in a number of dietary studies. The development of the techniques to quantify the FODMAP content of foods has greatly advanced our understanding of food composition. FODMAP composition is affected by food processing techniques and ingredient selection. In the USA, the use of high-fructose corn syrups may contribute to the higher FODMAP levels detected (via excess fructose) in some processed foods. Because food processing techniques and ingredients can vary between countries, more comprehensive food composition data are needed for this diet to be more easily implemented internationally.

ABSTRACT The Gibson and Dembo Teacher Efficacy Scale was modified for use in the special education resource-room context. A factor analysis of the modified instrument resulted in a factor structure comparable to one based on regular-education teachers, as reported in prior research. The relation between instructional supervision and teacher efficacy among these teachers was also examined. With sex, age, resource-room tenure, and job satisfaction held constant, the perceived utility—but not frequency—of supervision was significantly related to teacher efficacy. The implications of these findings for both research and practice in the special education context are considered.

Abstract This article focuses on measuring and explaining noncompliance in federally managed U.S. fisheries. Novel measurement techniques are used to characterize the extent and patterns of noncompliance in the northeast groundfish fishery. According to the authors' estimates, noncompliance increased substantially in 1986 and remained high through 1988 in the groundfish fishery. On Georges Bank during 1987, a quarter to a half of all groundfish vessels were identified as frequent violators, committing closed area violations on about one‐third of their trips and using illegal mesh on nearly all trips. Illegal earnings by a typical frequent violator operating in the groundfish fishery on Georges Bank amounted to $225,000 per year in 1987. A theory of compliance in fisheries is developed and applied to explain the trends and patterns of noncompliance in the northeast groundfish fishery. Biological and economic forces are shown to be dominant causes of the recent deterioration in compliance. Other contributing factors include weak sanctions and insufficient enforcement resources. The article concludes with a prognosis for the fishery and recommendations for improving compliance.

Abstract Researchers in the psychology of religion have begun utilizing priming methods to investigate the effects of the salience of religious concepts. These tightly controlled laboratory studies have demonstrated that priming religion may increase intergroup bias in both religious and nonreligious persons. The present study examined this possibility in a religiously and culturally diverse population using ecologically valid methods. Participants were recruited as they passed by either a religious or nonreligious structure in Western Europe. Participants in the religious context self-reported more negative attitudes toward non-Christian groups, more conservative political attitudes, and more personal religiousness and spirituality regardless of their personal belief in God. Results are discussed in terms of intergroup bias and salience of religious norms and stereotypes across cultures. Notes 1There were no significant differences between nationalities of participants, countries of collection, weather conditions, or times of day. 2Given the expected diversity of the sample, target groups were selected to represent attitudes toward a wide variety of groups unrelated to the religious context. Groups were selected to represent religious outgroups, religious value violating outgroups, racial outgroups, and social status outgroups. Note. *p < .05 **p < .005 ***p < .001. 3All attitude items remained significant when participants from London were removed from analysis except for attitudes toward foreigners (p = .12).

Organizations that are competing in dynamic global markets are increasingly adopting ambidextrous strategies where exploration and exploitation capabilities are combined simultaneously. However, ambidextrous work raises new challenges for human resource management (HRM). Based on 21 interviews with managers in seven multinational firms in Europe, we investigate how ambidextrous work in smart city work is supported through HRM systems. Our findings suggest a complex mix of three different HRM systems (one at corporate and two at project levels) designed to support ambidextrous exploratory and exploitation work. Specifically, corporate HRM systems focused on incentives and development of dual capabilities for smart city managers (SCMs). At project levels, interconnected explorative and exploitative HRM systems offered tailored managerial tools to support social integration and knowledge management between internal and external employees. Theoretical contributions, future research paths, and practical implications are addressed.

This study examined the geologic and evolutionary subject matter and views of inquiry and nature of science (NOS) of a group of 5th–9th grade teachers, and a comparison group, before and after participating in an inquiry-based professional development (PD) experience. Project teachers participated in an intensive, week-long, resident institute where they learned about geology, evolutionary concepts, NOS, and inquiry while engaging in an authentic scientific investigation. They were also given support in how to teach these topics using an inquiry-based approach. Analyses of data indicate that project teachers showed greater gains in subject matter than comparison teachers and the relative change was significantly different statistically. Furthermore, most project teachers demonstrated a shift from less informed to more informed views of inquiry and NOS and the relative change between participant and comparison teachers was significantly different statistically. These gains are promising because they suggest that short-term and intensive PD can support teachers in enhancing their knowledge and views. Moreover, analysis of post-programme questionnaires and interviews indicated that supporting teachers in reflecting on the relationship between their former classroom teaching practice, and new knowledge acquired during PD, may be an important link in enhancing teacher knowledge and supporting change in practice. This suggests that enhanced knowledge and views may not be the only factor contributing to changing one's practice. The study points to the importance of reflection in promoting teacher change. Results from this study add insights to supporting teachers in enacting inquiry-based instruction and teaching about NOS in their classrooms.

The concept of empowerment has become popular within the human service professions, but little agreement about its meaning or dimensions has been displayed. The authors describe an effort to clarify this elusive concept by integrating theory with practitioner perspectives. A focused, multiple-case-study method was used to gather the perspectives of human services workers on empowerment practice in the field. The authors identify areas of convergence and divergence between empowerment theory and practice.

Consensually held ideologies may serve as the cultural "glue" that justifies hierarchical status differences in society (e.g. Augustinos, 1998). Yet to be effective these beliefs need to be embraced by low-status groups. Why would members of low-status groups endorse beliefs that justify their relative disadvantage? We propose that members of low-status groups in the United States may benefit from some system-justifying beliefs (such as the belief in meritocracy) to the extent that these beliefs emphasize the perception of control over future outcomes. In 2 studies, among women, lower-SES women, and women of color, we found a positive relationship between the belief in meritocracy and well-being (self-esteem and physical health) that was mediated by perceived control. Members of low-status groups may benefit from some system-justifying beliefs to the extent that these beliefs, like the belief in meritocracy, emphasize the perception of control over future outcomes.

In this paper we examine the behavior of the mean residual life function in the case of certain types of non-monotonic failure rates and give conditions for the validity of the reciprocity of the shape. Some examples are given to illustrate the results

Daily life has changed for families due to the COVID-19 pandemic. The aim of this repeated cross-sectional study was to describe movement behaviours in Canadian children and youth 6 months into the pandemic (T2; October 2020) compared with the start of the pandemic (T1, April 2020). An online survey was distributed to parents (N = 1568) of children and/or youth (5–17 years; 58% girls) in October 2020. The survey assessed changes in movement behaviours (physical activity and play, sedentary behaviours, and sleep) from before the pandemic to October 2020 (T2). We compared these data with spring data (T1; April 2020; Moore et al. 2020; Int. J. Behav. Nutr. Phys. Act, 17:85) collected using identical methodology (N = 1472; 54% girls). We report correlations between movement behaviours and relevant parental factors and provide word frequency distributions for open-ended responses. During the second wave, 4.5% of children (4.6% girls; 4.3% boys) and 1.9% of youth (1.3% girls, 2.4% boys) met the movement guidelines (3.1% overall). Whereas, during the first wave, 4.8% (2.8% girls, 6.5% boys) of children and 0.6% (0.8% girls, 0.5% boys) of youth were meeting combined guidelines (2.6% overall). Parental support was correlated with their child’s movement behaviours (T1 and T2). Our study demonstrates the ongoing challenges for children and youth to engage in healthy movement during the pandemic. Novelty: Our large-scale national study demonstrates that children and youth were not meeting the 24-hour movement guidelines during the second wave of the pandemic. Our findings illustrate the need to protect children and youth from the collateral consequences of the pandemic.

This study looks at the differential effects of men and women entrepreneurs' human capital and network diversity on the likelihood of using external sources of financing (sources other than personal savings, family and friends) in the context of a transitional economy. Moderated logistical regression models using survey data from men and women new venture owners in Bulgaria (n = 555) suggest the likelihood of using external sources of financing is positively and significantly associated with the diversity of the entrepreneur's social network. Further, this effect is moderated by gender, suggesting that men make a better use of their social networks to secure sources of external financing. Implications for managerial practice and public policy are discussed.

Achieving a consistent market orientation is a challenge for entrepreneurial manufacturers. This research seeks improved understanding of how internal process management assists and hinders small growing manufacturers in achieving the responsiveness component of a market orientation. Under process management, firms implement internal systems, procedures, and performance measures to improve performance and responsiveness to changing markets. Benefits include improved market sensing, two-way communication, and coordinated responses to market demands. Despite the potential benefits, researchers question whether the internal structure and control of process management will improve responsiveness in entrepreneurial firms. Process management may conflict with the organizational cultures, agility, and responsiveness of entrepreneurial companies. Research results identify how process management assists and hinders the responsiveness component of market orientation in small manufacturers. Management implications and strategies for coping with growth challenges are presented.

This research examines resilience from both cognitive and physiological perspectives and the relative importance of resilience for progression within an extremely physical training environment for 116 individuals. Our study provides a unique contribution as an examination of the combined effects of psychological and physiological resilience in the success of individuals in the first phase of a military special operations training course, the Navy's Basic Underwater Demolition/SEAL (BUD/S) course. Our study used the Connor-Davidson Resilience Scale (CD-RISC) for the psychological assessment and a blood sample to measure the concentrations of cortisol, DHEA and BDNF, each associated with stress adaptation and neuronal integrity. Our contributions include: heeding the call for more extensive research for resilience, examining physiological markers as predictors in training situations, combining psychological and physiological resilience into a single metric to assess resilience, and providing empirical support for the vital role of resilience in both stamina and persistence in training. Our findings indicate that both psychological and physiological resilience can be important predictors of persistence individually, but combining the measures provides a more holistic view to predict the success of an individual in this intensive training program. The present study has implications not only for the military community, but also for those individuals seeking elite performance in a broad array of fields, like professional athletes, CEO's, and emergency response workers.

Median regression analysis has robustness properties which make it an attractive alternative to regression based on the mean.In this paper,the missing information principle is applied to a right-censored version of the median regression model,leading to a new estimator for the regression parameters.Our approach adapts Efton's derivation of self-consistency for the Kaplan-Meier estimator to the context of median regression;we replace the least absolute deviation estimating function by its (estimated) conditional expectation given the data.For discrete covariates the new estimator is shown to be asymptotically equivalent to anad hocestimator introduced by Ying,Jung and Wei,and to have improved moderate-sample performance in simulation studies.

Abstract River herring—a collective name for the Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis—play a crucial role in freshwater and marine ecosystems along the Eastern Seaboard of North America. River herring are anadromous and return to freshwater habitats in the tens to hundreds of millions to spawn, supplying food to many species and providing nutrients to freshwater ecosystems. After two and a half centuries of habitat loss, habitat degradation, and overfishing, river herring are at historic lows. In 2013, National Oceanic and Atmospheric Administration Fisheries established the Technical Expert Working Group (TEWG) to synthesize information about river herring and to provide recommendations to advance the science related to their restoration. This paper was composed largely by the chairs of the TEWG subgroups and represents a review of the current state of knowledge of river herring, with an emphasis on identification of threats and discussion of recent research and management actions related to understanding and reducing these threats. Important research needs are then identified and discussed. Finally, current knowledge is synthesized, considering the relative importance of different threats. This synthesis identifies dam removal and increased stream connectivity as critical to river herring restoration. Better understanding and accounting for predation, climate change, and fisheries are also important for restoration. Finally, there is recent evidence that the effects of human development and contamination on habitat quality may be more important threats than previously recognized. Given the range of threats, an ecosystem approach is needed to be successful with river herring restoration. To facilitate this ecosystem approach, collaborative forums such as the TEWG (renamed the Atlantic Coast River Herring Collaborative Forum in 2020) are needed to share and synthesize information among river herring managers, researchers, and community groups from across the species’ range.

This paper presents an approach for characterizing the probability of adverse effects occurring in a population exposed to dose rates in excess of the Reference Dose (RfD). The approach uses a linear threshold (hockey stick) model of response and is based on the current system of uncertainty factors used in setting RfDs. The approach requires generally available toxicological estimates such as No-Observed-Adverse-Effect Levels (NOAELs) or Benchmark Doses and doses at which adverse effects are observed in 50% of the test animals (ED50s). In this approach, Monte Carlo analysis is used to characterize the uncertainty in the dose response slope based on the range and magnitude of the key sources of uncertainty in setting protective doses. The method does not require information on the shape of the dose response curve for specific chemicals, but is amenable to the inclusion of such data. The approach is applied to four compounds to produce estimates of response rates for dose rates greater than the RfD.

Legitimacy is a much used concept in the social sciences. However, the absence of precise operational meaning has prompted questions about its utility as an explanation of compliance with social norms. Most recently, Alan Hyde has argued that legitimacy cannot be disentangled from other explanations of compliance such as coercion and self‐interest and should, therefore, be abandoned. However, institutional, attitudinal, and behavioral dimensions of legitimacy can be operationalized. As part of our research on small claims courts we examined variations in institutional processes and legitimacy, gathered data on levels of voluntary compliance, and questioned defendants about their reasons for paying claims against them. We conclude that institutional legitimacy is related to voluntary compliance, and that the “language of obligation” is an important part of normal discourse. Operational meanings for legitimacy are available and empirical research about legitimacy should be a prominent part of the social science research agenda.

Nous proposons dans cet article une réflexion sur la notion d'ingénierie des EIAH (Environnements Informatiques pour l'Apprentissage Humain). Nous posons tout d'abord une définition de l'ingénierie des EIAH : travaux visant à définir des éléments de méthodes et de techniques reproductibles et/ou réutilisables facilitant la mise en place (conception – réalisation – expérimentation – évaluation - diffusion) d'environnements de formation ou d'apprentissage (dans leur articulation avec les dispositifs informatiques d'aujourd'hui) en permettant de dépasser le traitement ad hoc des problèmes. Après avoir mis en évidence l'intérêt de travailler sur l'ingénierie des EIAH en prenant comme exemple d'impact positif de constitution d'une ingénierie l'évolution des travaux en ingénierie des connaissances, nous mettons en évidence les problèmes que pose la constitution d'une ingénierie, c'est-à-dire, fondamentalement, le problème de l'articulation entre ingénierie et fondements théoriques. Nous proposons alors des pistes pour progresser vers une ingénierie des EIAH.
