Abstract
The catch performance of a traditional Ligurian boat seine, which is not in line with the European Union regulation, was compared with an experimental surrounding net without the purse line as a potential legal alternative. The relative catch performance between the two gear types was assessed using a new catch comparison method requiring neither paired data collection nor equal number of hauls with the two gears. The comparison was based on the catches of the three species that comprise the bulk of the catch in traditional Ligurian boat seine fisheries: Bogue Boops boops, Saddle Bream Oblada melanura, and Blotched Picarel Spicara maena. The experimental gear exhibited poor catch efficiency for all three species, since it was estimated that the catches would only be 2, 64, and 6%, respectively, of those with the boat seine. For both Bogue and Blotched Picarel these reductions in catch performance were found to be highly significant proving that the experimental surrounding net is not a viable solution to replace the traditional boat seine.

Abstract
Background.  Efavirenz (EFV), an antiretroviral medication used to treat human immunodeficiency virus (HIV) infection, can increase lipid levels. Because hyperlipidemia is associated with increased risk for cardiovascular (CV) events, this study compared the risk of CV events in patients initiating EFV-containing vs EFV-free antiretroviral regimens.
Methods.  Antiretroviral-naive HIV-positive (HIV+) patients ages 18–64 were selected from commercial and Medicaid insurance claims databases. Patients with ≥1 claim for antiretroviral medications between January 1, 2007 and December 31, 2013 were classified into 2 cohorts: EFV-containing or EFV-free regimens. Patients were required to have 6 months of continuous enrollment before initiation, with no evidence of a CV event during this time. Patients were observed from initiation until the occurrence of a CV event, disenrollment, or study end. Cardiovascular events were identified through diagnosis or procedure codes for myocardial infarction, stroke, percutaneous coronary intervention, or coronary artery bypass graft. We calculated unadjusted incidence rates (IRs) and fit propensity-score-weighted Cox proportional hazards models.
Results.  There were 22 212 patients (11 978 EFV-containing and 10 234 EFV-free) identified in the commercial database and 7400 patients identified (2943 EFV-containing and 4457 EFV-free) in the Medicaid database. Cardiovascular events were rare (commercial IR = 396 per 100 000 person-years; Medicaid IR = 973 per 100 000 person-years). In propensity-score-weighted models, hazards of CV events were significantly lower for EFV-containing regimens in the commercial database (hazard ratio [HR] = 0.68; 95% confidence interval [CI], .49–.93) No significant difference was found in the Medicaid database (HR = 0.83; 95% CI, .58–1.19).
Conclusions.  This analysis found no evidence of increased risk of CV events among HIV+ patients initiating EFV-containing regimens.

AbstractAs a consequence of the ongoing demographic change, osteoporosis is considered as one of the mayor challenges for the health care system of the 21stcentury. However, the exact etiology of osteoporosis is far from being understood. Some evidence suggests that changes in stem cell metabolism might contribute to development of the disease. Therefore we evaluated whether differences of the morphology and/or the energy metabolism of mitochondria can be observed between human bone marrow derived mesenchymal stem cells obtained from osteoporotic patients as compared to non-osteoporotic controls.Mesenchymal stem cells were isolated from the bone marrow of senile osteoporotic and non osteoporotic patients, osteoporosis being assessed by dual energy X-ray absorptiometry. We then confirmed the stemness of the cells by FACS analysis of the expression of surface markers and by conducting multi-lineage differentiation experiments. And we finally investigated mitochondrial morphology and function with electron microscopy of cryo-fixed samples and by high-resolution respirometry, respectively. In addition we compared the energy metabolism of the stem cells to those of the osteosarcoma cell line MG-63.The data show, for the first time, the applicability on stem cells of the methods used here. Furthermore, our results indicated that there are no obvious differences detectable in mitochondrial morphology between cells from osteoporotic and non osteoporotic donors and that these cells also seem to be energetically indistinguishable with unchanged rates of routine respiration and respiratory capacity as well as unaltered oxygen consumption rates linked to different respiratory complexes. In summary, we could not detect any evidence indicating major changes of mitochondrial features in cells from osteoporotic patients.
Metacognitive ability predicts hippocampal and prefrontal microstructure

Published: March 2016

AbstractThe ability to introspectively evaluate our experiences to form accurate metacognitive beliefs, or insight, is an essential component of decision-making. Previous research suggests individuals vary substantially in their level of insight, and that this variation predicts brain volume and function, particularly in the anterior prefrontal cortex (aPFC). However, the neurobiological mechanisms underlying these effects are unclear, as qualitative, macroscopic measures such as brain volume can be related to a variety of microstructural features. Here we used a newly developed, high-resolution (800µm isotropic) multi-parameter mapping technique in 48 healthy individuals to delineate quantitative markers ofin vivohistological features underlying metacognitive ability. Specifically, we examined how neuroimaging markers of local grey matter myelination, macromolecular and iron content relate to insight. Extending previous volumetric findings, we found that metacognitive ability, as determined by a signal-detection theoretic model, was positively related to the myelo-architectural integrity of aPFC grey matter. Interestingly, perceptual metacognition predicted decreased macromolecule content coupled with increased iron in the hippocampus and precuneus, areas previously implicated in meta-memory rather than meta-perception. Further, the relationship of hippocampal-precuneus and prefrontal microstructure to an auditory memory measure was respectively mediated or suppressed by metacognitive ability, suggesting a dynamic trade-off between participant’s memory and metacognition. These results point towards a novel understanding of the relationship between memory, brain microstructure, and metacognition.Significance StatementBy combining a signal-theoretic model of individual metacognitive ability with state of the art quantitative neuroimaging, our results shed new light on the neurobiological mechanisms underlying introspective insight. Myelination and iron are core determinants of both healthy brain maturation and neurodegeneration; particularly in the hippocampus where iron accumulation is linked to oxidative stress and inflammation. Our results may thus indicate that metacognition depends upon the development and integrity of a memory-related brain network, potentially revealing novel biomarkers of neurodegeneration. These results highlight the power of quantitative mapping to reveal neurobiological correlates of behaviour.

Authors: Ghauri Pervez , Rosendo-Rios Veronica 
Published: March 2016

Purpose– The purpose of this paper is to empirically examine organizational cross-culture differences in public-private research-oriented relationships. More precisely, it focusses on the analysis university-industry collaborations partnering for research agreements with the aim of fostering the transfer of knowledge and innovation. It analyzes the key organizational cross-cultural differences that could hinder the successful performance of these agreements from a relationship marketing (RM) perspective.Design/methodology/approach– Based on a comprehensive literature review of organizational culture and RM, a quantitative study was carried out and a structural equation model was proposed and tested.Findings– Cross-cultural organizational differences in private-public sectors are proved to negatively influence relationship performance. Market orientation difference appears as the most significant barrier to relationship performance, followed by time orientation difference and to a lesser extent flexibility difference.Originality/value– By integrating organizational culture and RM literatures, the main contribution of this paper is the cross-cultural analysis of private-public relationships (in this case university-industry relationships) from the perspective of RM. Hence, this research will inform management seeking to develop successful public-private collaborations by enhancing their understanding of cross-cultural factors underlying relationship success and failure.
An empirical note on entrepreneurship and unemployment
Authors: Apergis Nicholas , Payne James E 
Published: March 2016

Purpose– The purpose of this paper is to extend the existing literature on the causal dynamics between entrepreneurship and the unemployment rate (UR) in the use of the Kauffman Foundation index of entrepreneurial activity.Design/methodology/approach– Recently developed panel unit root tests with recognition of cross-sectional dependence and panel cointegration/error correction modeling techniques are applied to US States.Findings– The results indicate that the rate of entrepreneurship, the UR, and real per capita personal income are cointegrated. The panel error correction model reveals that bidirectional causality exists among the variables in both the short run and long run. With respect to entrepreneurship, an increase in the UR increases the rate of entrepreneurship, in turn, an increase in the rate of entrepreneurship lowers the UR. Moreover, the results also show a positive bidirectional relationship between the rate of entrepreneurship and real per capita personal income.Originality/value– Unlike other standard measures of entrepreneurship, this is the first empirical study of the causal dynamics between entrepreneurship and the UR using the Kauffman Foundation index of entrepreneurial activity.
Volunteerism, affective commitment and citizenship behavior
Authors: Jain Ajay K 
Published: March 2016

Purpose– The purpose of this paper is to investigate the relationship of altruistic and egoistic motives with person- and organization-oriented citizenship behaviors as mediated by affective commitment. The author hypothesized that altruistic motives are positively associated with person-oriented citizenship behavior and affective commitment while egoistic motives are positively associated with organization-oriented citizenship behavior and negatively associated with affective commitment.Design/methodology/approach– The data were collected from 248 middle and senior managers from 20 different locations of a power generation organization in India. Self- and other reported method were used to collect the data by administering the questionnaires.Findings– Results of structural equation analysis have supported, with some exception, the hypotheses. Affective commitment has mediated the relationship between motives and both forms of citizenship behavior. However, altruistic motives had shown a negative relationship with affective commitment and had a positive relationship with person-oriented citizenship behavior. Meanwhile, egoistic motives had a positive relationship with affective commitment and organization-oriented citizenship behavior.Practical implications– Results suggest that organizational citizenship behaviors (OCBs)per seis not important rather motives play an important role during the performance appraisal process. Further there is a differential impact of altruistic and egoistic motives on employees’ attitude and behavior, and both can coexist in this process.Originality/value– This is the first study on the relationship of motives, affective commitment and OCBs in India.
A test of a job demands-resources intervention
Authors: Wingerden Jessica van , Bakker Arnold B. , Derks Daantje 
Published: March 2016

Purpose– The purpose of this paper is to examine the impact of a job demands-resources (JD-R) intervention on psychological capital (PsyCap), job crafting, work engagement, and performance.Design/methodology/approach– This study used a quasi-experimental pre-test-post-test design with a control group. Healthcare professionals (n=67) were assigned to the JD-R intervention or a control group and filled out questionnaires before and after the intervention. To test the hypotheses, multivariate analyses of covariance were conducted.Findings– Results showed that participants’ PsyCap, job crafting, work engagement, and self-ratings of job performance significantly increased after the JD-R intervention.Research limitations/implications– Only healthcare professionals participated in the intervention study, which restricts the generalizability of the findings.Practical implications– The results illustrate that organizations can foster work engagement and improve performance by offering a JD-R intervention aimed at increasing PsyCap and job crafting at work. Organizations should acknowledge the importance of facilitating and stimulating a resourceful and challenging work environment.Originality/value– This is the first study that examined a JD-R intervention. The results contribute to JD-R theory by offering a first causal test. For the first time, a significant increase of job crafting behaviors after an intervention was found.
Coping style and gender effects on attitudinal responses to incivility
Authors: Welbourne Jennifer L. , Gangadharan Ashwini , Esparza Celina A. 
Published: March 2016

Purpose– The purpose of this paper is to examine whether emotion- and problem-focussed employee coping styles affect the relationship between workplace incivility and job attitudes (job satisfaction, sense of community), and whether these effects vary by gender.Design/methodology/approach– Survey methodology was used to obtain self-report data from a sample of 314 working adults (90 percent Hispanic, 62 percent female) enrolled in courses at a public university.Findings– Targets of workplace incivility experienced lower job satisfaction and sense of community at work. Employees who typically used problem-focussed coping (PFC) to respond to work stressors experienced greater negative outcomes associated with incivility. Mixed results were found for employees who typically engaged in emotion-focussed coping (EFC) at work: frequent use of avoidant coping and religious coping buffered against the impact of incivility, however, support seeking coping styles strengthened the negative outcomes associated with incivility. These effects varied by gender.Practical implications– The results highlight the benefits of two EFC styles (religious coping, avoidance coping) in the context of workplace incivility. The findings also indicate limitations of PFC and support seeking coping in the context of incivility. Accordingly, the authors make suggestions for managers to facilitate employees to overcome problems of incivility.Originality/value– Few studies have investigated qualities that enable employees to effectively manage incivility. Further, the role of coping styles in relation to incivility is relatively unexplored. To address these gaps, the authors examined the extent to which PFC and EFC styles impact the relationship between incivility and work attitudes.
Excessive change and coping in the working population
Authors: Johnson Kevin J. , Bareil Céline , Giraud Laurent , Autissier David 
Published: March 2016

Purpose– Two complementary objectives are addressed in this paper. First, several studies are introduced based on the assumption that organizational change is now excessive. The purpose of this paper is to propose an operational definition to change excessiveness, and the authors assess whether it is a generalized phenomenon at a societal level. Second, these studies are habitually mobilizing coping theories to address their purpose. However, an integrated model of coping, including appraisals and coping reactions towards change is still to be tested. Thus, the assessment is anchored in an application of the Stimulus-Response Theory of Coping (SRTC).Design/methodology/approach– A quantitative study is conducted by administering questionnaires to a nationwide representative sample (n=1,002). Anderson and Gerbing (1991) two-step approach is used to validate the study and tests its hypothesized model. Change excessiveness is measured in order to observe if it is a generalized phenomenon in the working population. Its effects on coping are modelled through the fully mediated SRTC. Therefore, the hypothetical model predicted that the relationships between the perception of excessive change contexts and negative coping reactions is fully mediated by negative appraisals towards change contexts.Findings– Perceptions of excessive change is a normally distributed and a statistically centralized phenomenon. As hypothesized, an structural equation modelling test of the SRTC shows a full mediation effect of negative appraisal between change intensity and negative coping to change.Originality/value– This paper empirically tests a nationwide sample where organizational change may be too excessive for individuals’ positive coping. It is the first to generalize the observation of change excessiveness as perceived by employees to a nationwide level. Moreover, it addresses the gap between change excessiveness and coping theories in modelling the SRTC through its three components: event, appraisals, and coping reactions. Finally, it presents managerial discussions towards the strategic necessity for organizational change and its potential “too-much-of-a-good-thing” effects.
Professional association group mentoring for allied health professionals
Authors: Coppin Rosalie , Fisher Greg 
Published: March 2016

Purpose– Mentoring is widely used in the health sector, particularly for early career professionals in the public health system. However, many allied health professionals are employed in private practice and rely on their professional association to provide mentoring support and training. This mentoring context is under-researched. The paper aims to discuss these issues.Design/methodology/approach– A purposeful sample of 15 allied health professionals were interviewed using semi-structured interviews that were then analyzed using template analysis.Findings– The many-to-many group mentoring program delivered valuable knowledge, diagnostic skills and networking opportunities but did not provide inclusion, role modeling or psychosocial support to participants. Also identified were structural and operational issues including; the role of the coordinator in addressing contribution reluctance and participant confidence, confidentiality issues, lack of mentor training and overall organization of the program.Practical implications– Group mentoring is a valuable method of delivery for professional associations. The many-to-many group mentoring model is beneficial in a situation where the availability of mentors is limited. Further, the importance of having a dedicated program coordinator and a skilled facilitator is emphasized.Originality/value– This research contributes to the limited literature on many-to-many group mentoring by reviewing the effectiveness of an existing many-to-many group mentoring program for allied health professionals delivered by a professional association.
Salesperson work engagement and flow
Authors: Medhurst Adrian R , Albrecht Simon L 
Published: March 2016

Purpose– The purpose of this paper is to provide an interpretation of the lived experiences of salespersons’ work engagement and work-related flow and how these states are related.Design/methodology/approach– A mixed-methods qualitative investigation on a sample of 14 salespeople from a large Australian-based consumer goods enterprise was conducted. Using interpretative phenomenological analyses and ethnographic content analyses the antecedents and conditions for salesperson work engagement and work-related flow were investigated.Findings– The data showed that affective, cognitive and conative dimensions underpinned the experience of work engagement and work-related flow. Work engagement was interpreted as an aroused and self-regulated psychological state of energy, focus and striving aimed to address the situational and task relevant opportunities and demands encountered. Work-related flow was characterized by passion, absorption, eudaimonia and automatic self-regulation of goal pursuit.Research limitations/implications– The sample was from a single manufacturing organization with sales roles focussed primarily on business-to-business selling, and as such the generalizability of results to salespeople working in different contexts (e.g. retail sales, telesales) needs to be established.Practical implications– The research helps sales managers to take more account of the conditions that foster salesperson engagement and flow.Originality/value– This study represents one of the first attempts to interpret, compare and contrast the lived experience of salesperson work engagement with that of work-related flow. The study also adds to the relative paucity of research published on work engagement using qualitative methods.
