Entrepreneurial Orientation and Business Performance: An Assessment of past Research and Suggestions for the Future

Entrepreneurial orientation (EO) has received substantial conceptual and empirical attention, representing one of the few areas in entrepreneurship research where a cumulative body of knowledge is developing. The time is therefore ripe to document, to review, and to evaluate the cumulative knowledge on the relationship between EO and business performance. Extending beyond qualitative assessment, we undertook a meta–analysis exploring the magnitude of the EO–performance relationship and assessed potential moderators affecting this relationship. Analyses of 53 samples from 51 studies with an N of 14,259 companies indicated that the correlation of EO with performance is moderately large (r = .242) and that this relationship is robust to different operationalizations of key constructs as well as cultural contexts. Internal and environmental moderators were identified, and results suggest that additional moderators should be assessed. Recommendations for future research are developed.
The interactive effect of marital conflict and stress reactivity on externalizing and internalizing symptoms: The role of laboratory stressors

Abstract Growing evidence supports the biological sensitivity to context theory, which posits that physiologically reactive children, as indexed by autonomic nervous system (ANS) reactivity to laboratory stressors, are more susceptible to both negative and positive environmental influences than their low reactive peers. High biological sensitivity is a risk factor for behavioral and health problems in the context of high adversity, whereas in contexts of low adversity it has been found to promote positive adaptation. However, several studies have shown the opposite effect, finding that children who exhibited high ANS reactivity in response to interpersonal stressors were buffered from the deleterious effects of marital conflict, whereas children who showed low ANS reactivity were more vulnerable to high levels of marital conflict. Using an ethnically diverse sample of 260 kindergartners (130 girls, 130 boys), the current study investigated whether the interaction effect of marital conflict and the two branches of ANS reactivity on children's externalizing and internalizing symptoms differs with the nature of the laboratory challenge task used to measure children's stress response. As hypothesized, results indicate that the interaction between ANS reactivity and marital conflict significantly predicted children's behavior problems, but the direction of the effect varied with the nature of the challenge task (i.e., interpersonal or cognitive). This study illustrates the importance of considering the effect of laboratory stimuli when assessing whether children's ANS reactivity moderates the effects of adversity exposure on adaptation.
When Stuff Happens: A Narrative Theory Perspective on Moderator Intervention in Brand Communities

Grievance redress is central to organizations’ duty to act in an ethical and socially responsible manner. In this era of Web 2.0, customer grievances are often posted to the online brand community forums. Addressing grievances posted in brand communities falls to moderators, who must respond carefully in order to enhance positive emotion within the community, decrease negative emotion, and encourage community continuance. This is particularly challenging given the neutrality and negativity effects of computer-mediated communication. In this paper, we adopt a narrative theoretic perspective to explain qualities of moderator’s communication that may be effective in addressing community grievances. We analyze data gathered from the Kraft Food Cooking Community (KFCC). Our findings provide modest support for narrative theory, but suggest that managing community emotion and managing community continuance may not be complementary goals.
The dual action of ozone on the skin

The aim of this brief review is to summarize the recent literature on the effect of ozone (O3) on cutaneous tissues. Recently it has been reported that a chronic contact with O3 can be deleterious for the skin. Our group and others have shown a progressive depletion of antioxidant content in the stratum corneum and this can then lead to a cascade of effects resulting in an active cellular response in the deeper layers of the skin. Using an in vivo model we have shown an increase of proliferative, adaptive and proinflammatory cutaneous tissue responses. On the other hand the well known activity of O3 as a potent disinfectant and oxygen (O2) donor has been also studied for therapeutic use. Two approaches have been described. The first consists of a quasi‐total body exposure in a thermostatically controlled cabin. This treatment has proved to be useful in patients with chronic limb ischaemia. The second approach is based on the topical application of ozonated olive oil in several kinds of skin infection (from soreness to diabetic ulcers, burns, traumatic and surgical wounds, abscesses and skin reactions after radiotherapy). We and other authors have observed a striking cleansing effect with improved oxygenation and enhanced healing of these conditions. It is now clear that, on the skin, O3, like other drugs, poisons and radiation, can display either a damaging effect from a long exposure or a beneficial effect after a brief exposure to O2 and O3 or to the application of ozonated oil to chronic wounds.
Modeling and Analyzing the Interaction between Network Rumors and Authoritative Information

In this paper, we propose a novel two-stage rumor spreading Susceptible-Infected-Authoritative-Removed (SIAR) model for complex homogeneous and heterogeneous networks. The interaction Markov chains (IMC) mean-field equations based on the SIAR model are derived to describe the dynamic interaction between the rumors and authoritative information. We use a Monte Carlo simulation method to characterize the dynamics of the Susceptible-Infected-Removed (SIR) and SIAR models, showing that the SIAR model with consideration of authoritative information gives a more realistic description of propagation features of rumors than the SIR model. The simulation results demonstrate that the critical threshold λc of the SIAR model has the tiniest increase than the threshold of SIR model. The sooner the authoritative information is introduced, the less negative impact the rumors will bring. We also get the result that heterogeneous networks are more prone to the spreading of rumors. Additionally, the inhibition of rumor spreading, as one of the characteristics of the new SIAR model itself, is instructive for later studies on the rumor spreading models and the controlling strategies.
Fighting for the finest image we have of her: Patriotism and Oppositional Politics

Taking direct examples from the author’s own international research this chapter illustrates the patriotism of social change activists. It points out that one characteristic which people of this description share, even in different times and in different countries, is a professed deep love for their country which contrasts with the way in which they have often been portrayed: as disloyal citizens, if not outright traitors.
Contact analysis and mathematical modeling of traveling wave ultrasonic motors

An analysis of the contact layer and a mathematical modeling of traveling wave ultrasonic motors (TWUM) are presented for the guidance of the design of contact layer and the analyses of the influence of the compressive force and contact layer on motor performance. The proposed model starts from a model previously studied but differs from that model in that it adds the analysis of the contact layer and derives the steady-state solutions of the nonlinear equations in the frequency domain, rather than in the time domain, for the analyses of vibrational responses of the stator and operational characteristics of the motor. The maximum permissible compressive force of the motor, the influences of the contact layer material, the thickness of the contact layer, and the compressive force on motor performance have been discussed. The results show that by using the model, one can understand the influence of the compressive force and contact layer material on motor performance, guide the choice of proper contact layer material, and calculate the maximum permissible compressive force and starting voltage.
Robust Static and Fixed-order Dynamic Output Feedback Control of Discrete-time Lur'e Systems

Abstract This paper considers the design of static and fixed-order dynamic output feedback controllers for discrete-time Lur'e systems with sector-bounded nonlinearities and polytopic parametric uncertainty. Controller design equations are derived for systems with multiple states, outputs, and nonlinearities in terms of linear matrix inequalities (LMIs). The design methods are based on parameter-dependent Lyapunov functions (PDLFs) combined with the latest in theoretical and iterative numerical methods for solving certain classes of nonconvex inequalities. The design methods are illustrated in several numerical examples.
Nutritional Therapy for Glycogen Storage Diseases

Glycogen storage diseases (GSDs) are a group of inherited disorders characterized by enzyme defects that affect the glycogen synthesis and degradation cycle, classified according to the enzyme deficiency and the affected tissue. The understanding of GSD has increased in recent decades, and nutritional management of some GSDs has allowed better control of hypoglycemia and metabolic complications. However, growth failure and liver, renal, and other complications are frequent problems in the long-term outcome. Hypoglycemia is the main biochemical consequence of GSD type I and some of the other GSDs. The basis of dietary therapy is nutritional manipulation to prevent hypoglycemia and improve metabolic dysfunction, with the use of continuous nocturnal intragastric feeding or cornstarch therapy at night and foods rich in starches with low concentrations of galactose and fructose during the day and to prevent hypoglycemia during the night.
Pre‐schoolers, parents and supermarkets: co‐shopping as a social practice

The objective of this paper was to examine the co-shopping practices of children and parents in supermarkets, i.e. the practical enactment of grocery shopping. Our special focus is on how informal consumer training occurs during parent–child interaction. We use observational data collected in spring 2008 in different Estonian supermarkets, postshopping interviews with parents and focus group interviews with their children. Our analysis is informed by practice theory, which helps to look in detail at how the activities in a particular situation are coordinated by understandings and procedures, and are guided by the engagement in a particular shopping trip. Co-shopping interactions mostly revolve around particular material objects, although not exclusively. Product choice is a deeply contested area, where both parents and children face numerous pressures in this situation of two-way socialization. There are implications for consumer education more broadly. To accomplish lasting and meaningful effects on the everyday lives of families, there has to be a wider range of actors – supermarkets, producers, governmental bodies, schools and families – who care about both formal and informal consumer education.
Osmostress response in Bacillus subtilis: characterization of a proline uptake system (OpuE) regulated by high osmolarity and the alternative transcription factor sigma B

Exogenously provided proline has been shown to serve as an osmoprotectant in Bacillus subtilis. Uptake of proline is under osmotic control and functions independently of the known transport systems for the osmoprotectant glycine betaine. We cloned the structural gene (opuE ) for this proline transport system and constructed a chromosomal opuE mutant by marker replacement. The resulting B. subtilis strain was entirely deficient in osmoregulated proline transport activity and was no longer protected by exogenously provided proline, attesting to the central importance of OpuE for proline uptake in high‐osmolarity environments. The transport characteristics and growth properties of the opuE mutant revealed the presence of a second proline transport activity in B. subtilis. DNA sequence analysis of the opuE region showed that the OpuE transporter (492 residues) consists of a single integral membrane protein. Database searches indicated that OpuE is a member of the sodium/solute symporter family, comprising proteins from both prokaryotes and eukaryotes that obligatorily couple substrate uptake to Na+ symport. The highest similarity was detected to the PutP proline permeases, which are used in Escherichia coli, Salmonella typhimurium and Staphylococcus aureus for the acquisition of proline as a carbon and nitrogen source, but not for osmoprotective purposes. An elevation of the osmolarity of the growth medium by either ionic or non‐ionic osmolytes resulted in a strong increase in the OpuE‐mediated proline uptake. This osmoregulated proline transport activity was entirely dependent on de novo protein synthesis, suggesting a transcriptional control mechanism. Primer extension analysis revealed the presence of two osmoregulated and tightly spaced opuE promoters. The activity of one of these promoters was dependent on sigma A and the second promoter was controlled by the general stress transcription factor sigma B.
Online Support Groups for Depression

This mixed-methods study aimed to explore the initial process of engagement with an online support group (OSG) for depression. Fifteen British National Health Service patients experiencing depression who had not previously used an OSG for depression were offered facilitated access to an existing peer-to-peer OSG for 10 weeks. Pre- and post-measures of depression, social support, and self-stigma were taken in addition to a weekly measure of OSG usage. A follow-up qualitative interview was conducted with a subsample of nine participants. Depression and self-stigma reduced over the 10-week period, but perceived social support did not change. There was no evidence of adverse outcomes. Perceived benefits of OSG participation included connection to others, normalization of depression, and stigma reduction. However, engagement with the OSG was generally low. Barriers included concerns over causing harm to others or being harmed oneself, feeling different from others in the group, and fears of being judged by others. OSGs may potentially reduce depressive symptoms and perceived self-stigma. However, considerable barriers may hinder people with depression from engaging with OSGs. Further work is needed to determine who will benefit most from participating in OSGs for depression and how best to facilitate engagement.
Detection of a Rapidly Metabolizing Portion of the Membrane Cardiolipin in Haemophilus parainfluenzae

Heterogeneity in the metabolism of cardiolipin (CL) has been detected in Haemophilus parainfluenzae. Pulse-chase experiments showed that a portion of the total CL incorporated and then lost 32P much more rapidly than the rest of the CL in the cells. The metabolism of each phosphate of the CL differed. The phosphate of the phosphatidyl glycerol (PG) portion of the CL had a more active metabolism than the phosphate of the phosphatidic acid portion of the molecule. Only a portion of the PG pool contributed to the formation of CL. Ethylenediaminetetraacetic acid inhibited the CL-specific phospholipase D in vitro and, when added to growing cells, resulted in more rapid PG metabolism, suggesting that CL hydrolysis contributed to the PG pool.
Active relocation of chromatin and endoplasmic reticulum into blebs in late apoptotic cells

Plasma membrane blebbing is a defining characteristic of apoptosis, but its significance is not understood. Using live-cell imaging we have identified two phases of apoptotic blebbing. The early phase is restricted to adherent cells, and is prevented by the Rho-activated kinase inhibitor Y27632. The late phase is partially resistant to Y27632, and generates morphologically distinct membrane protrusions that are likely precursors to apoptotic bodies. Late blebbing is observed in all apoptotic cells tested. It occurs at a fixed period before phosphatidyl serine exposure, indicating that it is a universal and important feature of apoptosis. Late blebs contain a cortical layer of endoplasmic reticulum that often surrounds condensed chromatin, while other organelles are excluded. The appearance in some apoptotic cells of partially formed sheets of endoplasmic reticulum suggest that these cortical layers are newly formed by the remodelling of the endoplasmic reticulum of interphase cells. Formation of endoplasmic reticulum and chromatin-containing blebs requires both actin and microtubules, and is prevented by the caspase-6 inhibitor zVEID.fmk.
Culture and Gender Differences in the Perception of Friendship by Adolescents

This study examines personal collectivism and individualism (or allocentrism and idiocentrism) in relation to the perception of same-sex friendships among adolescents living in a multi-ethnic context in the Netherlands. Respondents originally from collectivist cultures were more allocentric than respondents originally from individualist cultures. Among the former group allocentrism was unrelated to idiocentrism, whereas a negative relation was found among the latter group. Allocentrismwas related toa greater sensitivity tofriends, using more ascribedfeatures indescribing friends, having fewer friends but seeing their relationship as closer, perceiving less intimacy with other-than-best-friends, and endorsing rules about relations with third parties more. Idiocentrism was related to less sensitivity to friends, using more personal characteristics in describing friends, but also to having fewer friends, talking less intimately with others, and endorsing friendship rules about intimacy less. Additionally, ge.
Leadership for Equity and Social Justice in Arab And Jewish Schools in Israel: Leadership Trajectories and Pedagogical Praxis

The research investigated how principals in Israel’s Jewish and Arab school systems perceive and practice their role in promoting equitable education to bridge socio-economic and pedagogic gaps. It asked how Jewish and Arab principals understand the concept of social justice and what they do in order to promote social justice reality in their schools. Semi-structured interviews were conducted with 10 Arab and Jewish principals. Analysis of interviews indicated that Israeli education policy perpetuates ethnic and social gaps. The principals reported different personal trajectories that shaped their perceptions of social and described strategies used to promote social justice.
Cognitive Styles: an integrated model

Abstract Cognitive styles are potentially useful in education as a means of characterizing stable individual differences that influence the effectiveness of teaching and learning. However, anyone interested in using styles in either research or practice is faced with a literature that is not only disorganized but also dated. Little basic research is being done to clarify the conceptual and measurement problems that bedevil the field. One way to revive interest in basic research would be to link ‘traditional’ conceptions of cognitive styles with the more vigorous field of cognitive psychology. This might result in new ways of conceptualizing individual styles, as well as resolving the problem of the relationships between styles. In this paper, I take a step in this direction by integrating some of the more common conceptions of cognitive styles into an information processing model of cognition.
Self-other agreement in job performance ratings: a meta-analytic test of a process model.

This meta-analysis explores agreement in self- and supervisory ratings of job performance (k = 128 independent samples). It suggests a 3-stage model of the rating process and reviews the empirical evidence for the relevance of each of these 3 stages to an understanding of agreement in ratings. The proposed 3-stage model serves as the guiding rationale for the examination of an extensive set of variables that moderate rater agreement. Results are reported for 2 indicators of rater agreement (correlational and mean-level agreement). Self-supervisor ratings yielded an overall correlation of . 22 (rho = .34; k = 115; n = 37,752). Position characteristics and the use of nonjudgmental performance indicators were the main moderators. Leniency in self-ratings is indicated by higher mean levels of self-ratings compared with supervisory ratings. Within Western samples, performance self-ratings showed leniency (d = 0.32, Delta = .49; k = 89; n = 35,417) dependent on contextual features, scale format, and scale content.
IMPACT OF ORGANIZATIONAL CITIZENSHIP BEHAVIOR ON ORGANIZATIONAL PERFORMANCE: A REVIEW AND SUGGESTIONS FOR FUTURE RESEARCH

Despite. the widespread interest in the topic of organizational citizenship behaviors (OCBs), little empirical research has tested the fundamental assumption that these forms of behavior improve the effectiveness of work groups or organizations. This article examines the assumption that OCBs improve the effectiveness of work groups or organizations in which they are exhibited. First, several theoretical and conceptua1 explanations of why OCBs may improve organizational effectiveness are provided. Following this, a review of the available empirical evidence is provided. The results of this review indicate that OCBs make important contributions to the variance in organizational effectiveness, although helping behavior tends to have more system- atic effects than either sportsmanship or civic virtue. Finally, the implications of these findings for future research are discussed.
Action phases and mind-sets

The focus of this chapter is on the course of action, which is understood to be a temporal, horizontal path starting with a person's desires and ending with the evaluation of the achieved action outcome. The phenomena of choosing an action goal, initiating the appropriate actions, and executing these actions are assumed to be situated in between. This comprehensive perspective conceives of the course of action as a number of consecutive, distinct segments or phases. It raises questions concerning how people choose action goals, plan and enact their execution, and eaaluate thek efforts. The concept of "mind-set" is employed to find answers to these questions in terms of the cognitive processes or orientations that allow for easy completion of the different action phases.
Probabilistic modeling of single-trial fMRI data

Describes a probabilistic framework for modeling single-trial functional magnetic resonance (fMR) images based on a parametric model for the hemodynamic response and Markov random field (MRF) image models. The model is fitted to image data by maximizing a lower bound on the log likelihood. The result is an approximate maximum a posteriori estimate of the joint distribution over the model parameters and pixel labels. Examples show how this technique can used to segment two-dimensional (2-D) fMR images, or parts thereof, into regions with different characteristics of their hemodynamic response.
Dissipativity Theory for Nesterov's Accelerated Method

In this paper, we adapt the control theoretic concept of dissipativity theory to provide a natural understanding of Nesterov's accelerated method. Our theory ties rigorous convergence rate analysis to the physically intuitive notion of energy dissipation. Moreover, dissipativity allows one to efficiently construct Lyapunov functions (either numerically or analytically) by solving a small semidefinite program. Using novel supply rate functions, we show how to recover known rate bounds for Nesterov's method and we generalize the approach to certify both linear and sublinear rates in a variety of settings. Finally, we link the continuous-time version of dissipativity to recent works on algorithm analysis that use discretizations of ordinary differential equations.
