AbstractGynodioecy, the coexistence of females and hermaphrodites, occurs in 20% of angiosperm families and often enables transitions between hermaphroditism and dioecy. Clarifying mechanisms of sex determination in gynodioecious species can thus illuminate sexual system evolution. Genetic determination of gynodioecy, however, can be complex and is not fully characterized in any wild species. We used targeted sequence capture to genetically map a novel nuclear contributor to male sterility in a self-pollinated hermaphrodite ofFragaria vescasubsp.bracteatafrom the southern portion of its range. To understand its interaction with another identified locus and possibly additional loci, we performed crosses within and between two populations separated by 2000 km, phenotyped the progeny and sequenced candidate markers at both sex-determining loci. The newly mapped locus contains a high density of pentatricopeptide repeat genes, a class commonly involved in restoration of fertility caused by cytoplasmic male sterility. Examination of all crosses revealed three unlinked epistatically interacting loci that determine sexual phenotype and vary in frequency between populations.Fragaria vescasubsp.bracteatarepresents the first wild gynodioecious species with genomic evidence of both cytoplasmic and nuclear genes in sex determination. We propose a model for the interactions between these loci and new hypotheses for the evolution of sex determining chromosomes in the subdioecious and dioeciousFragaria.
Evaluating the service provision for ethnic minorities in Islington in the treatment of substance misuse
Authors: Fernandez Jeff 
Published: August 2015

Purpose
– The purpose of this paper is to illustrate how local drug services use their senior staff to respond to emerging ethnic groups presenting to treatment using flexible thinking and innovative processes.

Design/methodology/approach
– The methodology was a case study design that used a semi-structured questionnaire that looked at two drug services and their staff’s influence on service delivery in different boroughs of east London.

Findings
– The research found very innovative findings from the two boroughs. The boroughs had different racial mixes and therefore differing populations presenting to their local drug services. However, they used flexible approaches to structure their services to engage with emerging ethnic minority populations in drug treatment. From the findings, these different approaches and structures of providing drug treatment were very important. Approaches, for example, of clinical staff offering a “rapid assessment” are particularly important in engaging and retaining ethnic minority populations. Also, using flexible thinking within the staff team enables drug services to adapt treatments to be flexible in responding to emerging ethnic populations.

Practical implications
– This paper shows that thinking in designing approaches to drug treatment shows that ethnic minority populations can be successfully engaged in drug treatment. This has implications for drug treatment nationally and across Europe where there are “emerging” ethnic populations presenting for drug treatment.

Originality/value
– This paper shows that drug services can adapt and change to their different ethnic minority populations if they can able to be flexible in their clinical approach to service provision.
Central city vibrancy and new business venturing
Authors: Gross Stephen , Campbell Noel 
Published: August 2015

Purpose– Researchers have identified the “vibrancy” of living in a spatially defined area as having a positive impact on entrepreneurial activity, measured as new business start-ups. Vibrant areas attract and facilitate would-be entrepreneurs, and attract other entrepreneurs and the skilled people and other resources who can take advantage of the opportunities other entrepreneurs create. A vibrant locale, then, can trigger a virtuous cycle of entrepreneurially led economic and social development. The purpose of this paper is to test this hypothesis.Design/methodology/approach– The unit of observation is the county of the US Census-designated central city of metropolitan statistical areas. The authors use principal components analysis to recover scores from a variety of measures of urban vibrancy. The authors embed these scores in an OLS model of new business venturing.Findings– Within a standard model of new business launches that is designed to be comparable across time and space, the inclusion of principal components scores based on urban vibrancy measures adds little explanatory power.Social implications– Policies designed to make an urban area “more vibrant” as a means to the end of attracting new establishment launches may be less successful than policymakers hope.Originality/value– To the best of our knowledge, this is the first paper to apply principal components analysis to measures of urban vibrancy within a general model of new business venturing.
Measuring and testing general fundamental attribution error in entrepreneurship effecting public policy
Authors: Fiore Robert A. , Lussier Robert N. 
Published: August 2015

Purpose
– The purpose of this paper is to empirically test for fundamental attribution error (FAE) – the naturally occurring bias of humans to over-attribute business success to celebrity-entrepreneur disposition.

Design/methodology/approach
– Employing a five-step process, this paper measures and tests for FAE bias in entrepreneurial situations. The methodology includes anecdotal historical evidence; developing a FAE survey instrument; having 101 respondents classify variables; statistically testing and validating the instrument; and then statistically identifying the importance of each factor with a sample 105.

Findings
– Significant statistical evidence for an active FAE bias was found. People do tend to attribute business success to entrepreneurial dispositions, rather than team behavior and circumstantial outcome factors which can reduce the effectiveness of public policy.

Research limitations/implications
– There is minimal research on FAE in entrepreneurship effecting public policy, thus there is a need for research to better understand factors of business outcomes actually based on entrepreneurial dispositions vs team behavior and circumstantial-situational factors.

Practical implications
– FAE bias may lead the general public, entrepreneurs, and public policy makers to overemphasize the impact of the entrepreneur’s behavior and especially the dispositional factors of the celebrity-based entrepreneur when assessing causation of firm performance. This would under-emphasize the value of other organizational factors. Misidentification of true cause-effect factors may lead to inappropriate managerial conclusions and introduction of error in public policy decisions.

Originality/value
– Although FAE is primarily a psychological literature concept, this is the first study to contribute empirical evidence of the FAE of professionals employed in business as it applies to entrepreneurship and economic outcomes.
Economic freedom, homeownership, and state labor market conditions
Authors: Heller Lauren R. , Stephenson E. Frank 
Published: August 2015

Purpose– The purpose of this paper is to reconcile research finding that labor market outcomes are related to economic freedom for entrepreneurs and separate research finding that higher homeownership rates are associated with more unemployment.Design/methodology/approach– Using panel data covering the 50 states over 1981-2009, this paper analyzes the relationship between labor market conditions, economic freedom, and homeownership rates.Findings– The results indicate that economic freedom is associated with favorable labor market conditions but that the relationship between homeownership and poor labor market outcomes is small and insignificant in most specifications once economic freedom is accounted for.Originality/value– This paper is the first paper to examine the relationship between labor market outcomes and both homeownership and economic freedom. The results suggest that the economic environment for entrepreneurs is more important than any rigidities created by homeownership.
Corruption, debt financing and corporate ownership
Authors: Lemma Tesfaye T. 
Published: August 2015

Purpose– The purpose of this paper is to examine the influence of perceived corruption on debt financing and ownership structure decisions of firms within the context of ten African countries.Design/methodology/approach– The paper analyses 15-year (1996-2010) data pertaining to 556 non-financial firms drawn from ten African countries using models that link firm financing, ownership structure, and perceived corruption. It uses robust procedures including system-generalized method of moments, general least square, and Logistic (LOGIT) regression.Findings– The study finds evidence that perceived corruption is important in shaping debt financing and ownership structure decisions of firms in Africa. Particularly, it finds that: first, higher levels of perceived corruption lead to firms using higher levels of short-term leverage, lower levels of long-term leverage and debts with shorter maturities and second, firms in countries with higher levels of perceived corruption respond to weaknesses in the law enforcement institutions through higher ownership concentration and controlling block shareholding.Research limitations/implications– As in most empirical studies, this study focused on listed firms. Nonetheless, future studies that focus on non-listed firms could add additional insights to the extant literature.Practical implications– The study provides empirical support for the argument that perceived corruption in a country distorts corporate governance. The policy implication of the findings is that governments, by taking steps that curb corruption, could enhance corporate governance by inducing firms into optimal debt financing and ownership structure decisions.Originality/value– The study focuses on firms in African countries for which studies such as this are non-existent.
Nonlinear ARDL approach, asymmetric effects and the J-curve
Authors: Bahmani-Oskooee Mohsen , Fariditavana Hadise 
Published: August 2015

Purpose– Previous research that investigated the effects of currency depreciation on the trade balance assumed that the adjustment of all variables in a given model is in linear fashion. The authors wonder if introduction of nonlinearity in the adjustment of some variables such as the exchange rate can shed additional light on evidence of the J-curve. The new approach also allows to test whether exchange rate changes have symmetric or asymmetric effects on the trade balance. Estimates of a trade balance model for Canada, China, Japan, and the USA reveal that the effects are indeed asymmetric. The paper aims to discuss these issues.Design/methodology/approach– The methodology is based on linear and nonlinear ARDL approach.Findings– When nonlinearity is introduced into testing approach for the J-curve, more evidence is found in support of the J-curve.Research limitations/implications– The models are estimated using aggregate trade flows of each country with the rest of the world, hence they suffer from aggregation bias. Using trade flows at bilateral level and at commodity level are highly recommended for future research.Originality/value– This is the first paper that applies nonlinear ARDL approach to test the short-run and long-run effects of currency depreciation on the trade balance.
Technical efficiency and its determinants factors in Spanish textiles industry (2002-2009)
Authors: De Jorge-Moreno Justo , Rojas Carrasco Oscar 
Published: August 2015

Purpose– The purpose of this paper is to provide new evidence about the technical efficiency and its determinants in Spanish textile sector during the period 2002-2009. The empirical results suggest that the effects of trade liberalization have led to higher levels of inefficiency in the Spanish sector, due to the lack of flexibility of firms to adjust to the environment, and perhaps to aggressive competition with fuzzy rules of the game. Controlling for specific factor like age, intensity of capital, salary by worker, regions and market share, the authors have obtained that the interaction between market share and size indicates that as firms have more size are also more inefficient.Design/methodology/approach– In this paper, the stochastic frontier production function is considered, specifically, a panel data version of Battese and Coelli (1995), in which the technical inefficiency is estimated from the stochastic frontier and simultaneously explained by a set of variables. This approach avoids the inconsistency problems of the two-stage approach used in other empirical works when analyzing the inefficiency determinants.Findings– This work provides new evidence about the technical efficiency and its determinants can be due to environmental or firm-specific factors in Spanish textile sector during the period 2002-2009. The authors have estimated the Cobb-Douglass stochastic production frontier following Battese and Coelli (1995) model to analyze an unbalanced panel.Originality/value– The empirical results suggest that the trend of the inefficiency shows a curvilinear behavior in the form of U (turning point third-quarter of 2004). This result is related to the efficiency analysis through Kernel distributions (in static and dynamic form) confirmed a clear process of divergence. In the period 2002-2005 the efficiency of the firms analyzed maintained higher levels than the 2005-2009 period where there is deterioration. This may be related to the increased competition due to the end of the Multi-Fiber Arrangement in January 2005 and the entry of Chinese products in 2004.
The shadow economy as a higher order construct inside European governance
Authors: Quintano Claudio , Mazzocchi Paolo 
Published: August 2015

Purpose
– Several dimensions of public governance occur while approaching the Shadow Economy (SE) phenomenon. The purpose of this paper is to study the SE by means of the European governance analysis by highlighting the main features of implications of the policy options. A statistical significance on the nexus between public governance and the SE appears with respect to the indicators taken into consideration except for the dimensions related to the tax system, which appear to be moderate in magnitude in terms of their effects.

Design/methodology/approach
– In order to evaluate data from 32 European Union countries during 2011, a hierarchical component model (HCM) in the context of the structural equation model (SEM) partial least squares (PLS) is utilised. Two different procedures are considered: a two-stage approach (TSA) and the repeated indicators approach (RIA).

Findings
– The two procedures (RIA and TSA) proposed in the model have about the same impact on the SE. Evidence suggests that the manifest variables joined to the regulatory system, business regulation and wealth level significantly affect the SE. In contrast, different dimensions connected to the tax system need to be considered to avoid that there be no significant effects on the SE from taxes.

Research limitations/implications
– A critical evaluation of the policy implications of the results are included, by focusing on the effects on the SE.

Practical implications
– This paper suggests where more emphasis should be placed when referring to the statistical results in dealing with the SE.

Originality/value
– To the authors’ knowledge, this is the first attempt to explore the SE while using an HCM (also known as higher order model) performed in a SEM-PLS procedure. The model proposed discerns the relevance and the marginal impact of several dimensions of policy interventions.
Analyzing CSR issues for supply chain performance system using preference rating approach
Authors: Tyagi Mohit , Kumar Pradeep , Kumar Dinesh 
Published: August 2015

Purpose
– The purpose of this paper is to identify the significant corporate social responsibility (CSR) issues and to analyze the interaction among them in order to improve supply chain performance (SCP) system of an organization.

Design/methodology/approach
– To achieve the objective, a preference rating approach (synthesized in company preference rating (CPR) and company satisfaction assessment (CSA) approaches) has been used in two stages as: stage 1, relative importance rating (RIR) of identified issues has been computed using CPR approach. For this, preference graphs have been developed based on the field expert’s opinions using graph-theory-based representation technique. In stage 2: competitive priority ratings of CSR issues with respect to competitive strategies have been calculated using CSA approach.

Findings
– Based on RIRs (stage 1), it has been noticed that issue namely “social benefits for employees” is more desirable among all considered issues. In stage 2, based on competitive priority ratings, the issue “social benefits for employees” is more important for an organization to build a better brand reputation through CSR activities and issue “degree of CSR implementation” is more significant in order to improve the SCP of an organization. The issue “environmental protection” helps the organization to reduce their overall environmental impact and also provides an aid in achieving long-term sustainable goals of an organization.

Research limitations/implications
– The findings of present research gives an idea about the importance of CSR issues, based on this, managers can decide, which issue is more significant and can help in taking decisions and framing strategies in context of CSR for improving the SCP of their organization effectively and efficiently.

Originality/value
– As per the best knowledge, recognized CSR issues have been considered first time to quantify the CSR-based SCP of Indian automobile industries located near around Delhi region, India. This paper may provide an aid to the managers in making the CSR-based policies to enhance their SCP.

Ecosystem response to interventions: lessons from restored and created wetland ecosystems
Authors: Moreno‐Mateos David , Meli Paula , Vara‐Rodríguez María Isabel , Aronson James 
Published: August 2015

Summary

Current efforts to restore and create ecosystems require greater understanding of ecosystems’ responses to commonly used physical and biological intervention approaches to overcome ecological and technological limitations.

We estimated effect sizes from measurements of biotic assemblage structure and biogeochemical functions at 628 restored and created wetlands globally, in comparison with 499 reference wetlands. We studied the recovery trajectories of wetlands where different restoration or creation approaches were used under different environmental settings.

Although the variance explained by a linear mixed‐effects models was low (6–7%), the study of recovery trajectories showed that the restoration or creation approach had no significant effects in most environmental settings.

In particular, wetlands where surface modification and flow re‐establishment were used followed similar recovery trajectories regardless of whether they were revegetated or not. We even found potential detrimental effects of biological manipulations on the recovery of the plant assemblage, particularly in cold climates and in wetlands restored or created in agricultural areas.

Since physical interventions are required to recover or create the hydrological conditions of degraded or new wetlands, and given the high cost (22–73%) of biological interventions (i.e. revegetation), the need for biological interventions is, in most cases, unclear.

Our results highlight the urgent need to increase our understanding of the long‐term effects of restoration and creation actions in our aim to engage in large‐scale ecosystem management strategies for wetlands.

Synthesis and applications. These results suggest that, currently, the recovery and development processes of restored and created wetlands can be driven by spontaneous processes rather than by the response of wetlands to human interventions other than those targeted to restore hydrological conditions that existed prior to disturbance. However, given the synthetic nature of the data set, the mixed nature of available data and the limited number of measures we found to estimate recovery, caution must be exercised when adapting the results presented here to the planning and execution of specific ecosystem restoration projects.

AbstractAimTelephone health behaviour change interventions have shown potential as a medium for change. The aim of the present study was to evaluate the effectiveness of a telephone behaviour change program on weight and physical activity. It was hypothesised that participants would achieve significant improvements in body mass index (BMI) and physical activity at the completion of the program and at follow up.MethodsA six‐month health telephone behaviour change program was delivered by health professionals trained in health coaching methodology. Participants (n = 250) had two or more chronic disease risks, received five calls during the program and a follow up call 12–18 months after completion of the program.ResultsThe average participant age was 70, 72% were female and mean BMI was 28.90 kg/m2. Significant improvements in BMI were reported from baseline to post‐intervention (−1.70% change) and from baseline to follow up (−1.21% change). Changes in weight were significant from baseline to post‐intervention (−1.67% change) and not significant from baseline to follow up (−1.25% change). Significant changes in the average number of minutes spent in moderate to vigorous intensity physical activity (MVPA) per week were reported between baseline and post‐intervention and post‐intervention and follow up. From baseline to follow up, the average time spent in MVPA per week increased by 157 minutes. At follow up, 86% of participants maintained or further improved their health behaviour.ConclusionsThe present study demonstrated the potential effectiveness of a low‐dose telephone health behaviour change program in assisting participants to change and maintain their health behaviour.
