The effect of industrial competition on employment
Authors: Mendoza-Velazquez Alfonso 
Published: June 2017

PurposeThis study investigates the existence of Marshall, Jacob and Porter’s type of externalities in Mexico. We measure the impact of industrial specialization, competition and diversity on employment growth for the period 2004 to 2008.Design/methodology/approachThe analysis is based on data from 41 highly dynamic industrial clusters originally obtained by applying Porter’s (1998) methodology. We use a cross-section specification estimated via instrumental variables and two-stage least square estimation (2SLS) to control for endogeneity.FindingsOn average, we find that industrial specialization exerts a negative impact on employment growth within states and within clusters, indicating that traded industries in Mexico carry very little innovation, operate in early stages of the life cycle, face high costs of employment reassignation or exhibit low adaptability. A negative impact of specialization on employment conforms with Jacobs (1969) type of externalities and confirms what other studies have found in France (Combes, 2000), Korea (Leeet al., 2005) and the USA (Delgadoet al., 2014). The authors also find that competition generates more employment.Research limitations/implicationsIndustrial data at the sub-branch level were obtained from the Economic Census (EC) of the National Institute of Geography and Statistics (INEGI). The EC information for 2004 was still not fully compatible with the North America Industry Classification System (NAICS), with 262 of the 309 data at the fourth-digit level aligned to the USA. In addition, industrial information from the EC is recorded every four years, which prevents this study to use panel data techniques and it makes it impossible to use time series methods.Practical implicationsPolicymakers can clearly identify competition forces having a significant impact on employment growth. This can orient policymakers to implement measures to encourage the development of some of these clusters, as well as to identify some of the sources that drive specialization, competition and diversity.Originality/valueThis paper contributes to the debate on the existence of Marshallian (MAR), Jacobian and Porter externalities. This is the first study using the definition of traded clusters in Mexico, which allows the authors to identify how specialization, competition and diversity forces drive the dynamics of regional employment growth.
Exploring the role of leadership in territorial strategies for competitiveness
Authors: Larrea José Luis , Aranguren Mari Jose , Valdaliso Jesús M. 
Published: June 2017

Purpose
The purpose of this paper is to focus on the role of leadership in the design and implementation of territorial strategies for competitiveness. It attempts to address two research questions: first, how leadership is influenced by theory and the other way around, how theory is transformed through leadership; and second, what characteristics of leadership are most important to successfully implement territorial strategies.

Design/methodology/approach
The paper is based on a case study of the life experience of an individual who has worked in positions of high responsibility in the government, the private sector and at the university. It is based on first-person action research combined with the contrast of two other co-authors.

Findings
Three findings may be highlighted from this case study. First, the importance of having leaders learning from their own process of leadership and co-evolving with the need for transformation which requires territorial strategies at every moment. Second, the necessity of having leaders whose objectives are aligned with those of the territory. Third, that individual leadership must have three characteristics to implement successfully territorial strategies: a balance between the individual and the collective objectives, a systemic vision and a consciousness of one’s own role in the system and a multi-level dimension.

Originality/value
Although territorial strategies are becoming increasingly popular both in the academia and in the policy arena, one of their critical elements, the role of individuals and that of leadership in general have not been addressed neither by scholars nor by practitioners. This paper attempts to explore the role of leadership through a case study based on the life experience of an outstanding individual in one of the regions with the longest tradition on territorial strategies for competitiveness.
Enhancement of heat transfer in a square channel by roughened surfaces in rib-elements and turbulent flow manipulation
Authors: Liu Jian , Xie Gongnan , Sunden Bengt Ake , Wang Lei , Andersson Martin 
Published: June 2017

Purpose
The purpose of this paper is to augment heat transfer rates of traditional rib-elements with minimal pressure drop penalties.

Design/methodology/approach
The novel geometries in the present research are conventional cylindrical ribs with rounded transitions to the adjacent flat surfaces and with modifications at their bases. All turbulent fluid flow and heat transfer results are presented using computation fluid dynamics with a validated v2f turbulence closure model. Turbulent flow characteristics and heat transfer performances in square channels with improved ribbed structures are numerically analyzed in this research work.

Findings
Based on the results, it is found that rounded transition cylindrical ribs have a large advantage over the conventional ribs in both enhancing heat transfer and reducing pressure loss penalty. In addition, cylindrical ribs increase the flow impingement at the upstream of the ribs, which will effectively increase the high heat transfer areas. The design of rounded transition cylindrical ribs and grooves will be an effective way to improve heat transfer enhancement and overall thermal performance of internal channels within blade cooling.

Originality/value
The novel geometries in this research are conventional cylindrical ribs with rounded transitions to the adjacent flat surfaces and with modifications at their bases. The combination of cylindrical ribs and grooves to manipulate the turbulent flow.

Community resilience through entrepreneurship: the role of gender
Authors: Bakas Fiona Eva 
Published: June 2017

PurposeThis paper aims to contribute to entrepreneurship theorising by highlighting the salience of feminine caring positions in creating novel entrepreneurial roles and investigating how these roles contribute to community resilience. Using a critical feminist economics lens, alternative conceptualisations of the economy are expanded upon to reveal how an economic externality influences entrepreneurial discourse, gender roles and community resilience.Design/methodology/approachIn this interpretive approach, empirical evidence is drawn from six months of intensive ethnographic research with 20 tourism handicraft micro-entrepreneurs in Crete and Epirus, Greece, in 2012 and hence in the context of a macroeconomic crisis. Ethnographic interviewing and participant observation are used as the methods to achieve the research objectives.FindingsThematic analysis is used to investigate how gender roles and entrepreneurial roles interact and how this interaction influences community resilience to an economic crisis. Using the critical theory to critique neoclassical economics interpretations of entrepreneurship, it becomes evident that politico-economic structures perpetuating feminised responsibility for social reproduction configure feminine entrepreneurial roles, and these roles have a positive effect on increasing community resilience. By conceptualising entrepreneurial involvement as being primarily for community gain, participants highlight how feminine entrepreneurial discourse differs from the neoclassical economics entrepreneurial discourse of entrepreneurial involvement being primarily for individual gain.Social implicationsThis paper contributes to theoretical advancements on the role of gender in entrepreneurship and community resilience by investigating the entrepreneurs’ gendered responses to an exogenous shock. Providing insight into the role gender has in entrepreneurial adaptation and sustainable business practices means that new policies to combat social exclusion and promote rural development can be formulated.Originality/valueThe theoretical interplay between gender and entrepreneurship is investigated from a novel angle, that of critical feminist economics. The relationship between feminised interpretations of entrepreneurship and community resilience is brought to light, providing a unique insight into entrepreneurial resilience.

Team structure, skill mix and clinical outcomes
Authors: Merrick Eamon , Fry Margaret , Busby Grant Janie 
Published: June 2017

AbstractThe majority of presentations to Australian EDs are for semi‐urgent and non‐urgent complaints in the older adult. For these patient's treatment and care is typically delivered by loosely organised teams of professionals. While substantial research has examined the clearly defined, hierarchical team structures used during resuscitation events, little is known about the composition and functioning of teams involved in non‐urgent patient care in ED. Investigation of these team dynamics can identify personal and professional factors involved in the delivery of this care and enable the design of teams that enhance patient outcomes.

Published: June 2017

AbstractThe diamondback moth, Plutella xylostella (L.), uses sulfatases (SULF) to counteract the glucosinolate–myrosinase defensive system that cruciferous plants have evolved to deter insect feeding. Sulfatase activity is regulated by post‐translational modification of a cysteine residue by sulfatase modifying factor 1 (SUMF1). We identified 12 SULF genes (PxylSulfs) and two SUMF1 genes (PxylSumf1s) in the P. xylostella genome. Phylogenetic analysis of SULFs and SUMFs from P. xylostella, Bombyx mori, Manduca sexta, Heliconius melpomene, Danaus plexippus, Drosophila melanogaster, Tetranychus urticae and Homo sapiens showed that the SULFs were clustered into five groups, and the SUMFs could be divided into two groups. Profiling of the expression of PxylSulfs and PxylSumfs by RNA‐seq and by quantitative real‐time polymerase chain reaction showed that two glucosinolate sulfatase genes (GSS), PxylSulf2 and PxylSulf3, were primarily expressed in the midgut of 3rd‐ and 4th‐instar larvae. Moreover, expression of sulfatases PxylSulf2, PxylSulf3 and PxylSulf4 were correlated with expression of the sulfatases modifying factor PxylSumf1a. The findings from this study provide new insights into the structure and expression of SUMF1 and PxylSulf genes that are considered to be key factors for the evolutionary success of P. xylostella as a specialist herbivore of cruciferous plants.
The replicative lifespan‐extending deletion of SGF73 results in altered ribosomal gene expression in yeast

Published: June 2017

SummarySgf73, a core component of SAGA, is the yeast orthologue of ataxin‐7, which undergoes CAG–polyglutamine repeat expansion leading to the human neurodegenerative disease spinocerebellar ataxia type 7 (SCA7). Deletion of SGF73 dramatically extends replicative lifespan (RLS) in yeast. To further define the basis for Sgf73‐mediated RLS extension, we performed ChIP‐Seq, identified 388 unique genomic regions occupied by Sgf73, and noted enrichment in promoters of ribosomal protein (RP)‐encoding genes. Of 388 Sgf73 binding sites, 33 correspond to 5′ regions of genes implicated in RLS extension, including 20 genes encoding RPs. Furthermore, half of Sgf73‐occupied, RLS‐linked RP genes displayed significantly reduced expression in sgf73Δ mutants, and double null strains lacking SGF73 and a Sgf73‐regulated, RLS‐linked RP gene exhibited no further increase in replicative lifespan. We also found that sgf73Δ mutants display altered acetylation of Ifh1, an important regulator of RP gene transcription. These findings implicate altered ribosomal protein expression in sgf73Δ yeast RLS and highlight altered acetylation as a pathway of relevance for SCA7 neurodegeneration.
Building More Inclusive Solidarities for Socio‐Environmental Change: Lessons in Resistance from Southern Appalachia
Authors: Rice Jennifer L. , Burke Brian J. 
Published: June 2017

AbstractIt is increasingly recognized that socio‐environmental justice will not be achieved through liberal and cosmopolitical forms of activism alone. Instead, more diverse and inclusive solidarities must be achieved across political ideologies for transformative change. By engaging with one constituency often overlooked by mainstream environmentalists—rural, conservative Americans—we argue for a situated solidarity that can be forged among people whose views of nature, community, and politics differ significantly. This framework rejects totalizing expressions of global ambition that erase important place‐based differences. To explore this ethic, we examine a localized anti‐fracking campaign in western North Carolina to determine how place‐based forms of environmental resistance can be brought in closer connection with the cosmopolitical movement for climate and energy justice. This requires that cosmopolitical movements make room for more customary forms of cultural politics, while conservative movements look beyond their own place‐based struggles to resist mutually experienced forms of oppression.
Labour Regime Transformation in Myanmar: Constitutive Processes of Contestation
Authors: Arnold Dennis , Campbell Stephen 
Published: June 2017

ABSTRACTThis article studies the case of a workers’ strike in Myanmar's ready‐made garment sector to illustrate how differently‐situated actors have engaged at multiple scales to influence emerging forms of labour regulation in the country. The analysis is drawn out through the historicization of domestic regulatory transformation. As a hegemonic project targeting industrial peace for purposes of capital accumulation, Myanmar's labour regime has been shaped by various actors outside of government circles, including International Labour Organization (ILO) personnel, Myanmar trade unionists, foreign governments, transnational corporations, domestic capitalists and Myanmar workers. Proposing a multi‐scalar reading of labour regime transformation attentive to constitutive processes of contestation, the study analyses ways in which varied, and at times unofficial, relations coalesce to shape labour regulation.
The Persistence of Opportunistic Insider Trading
Authors: Cline Brandon N. , Gokkaya Sinan , Liu Xi 
Published: June 2017

AbstractWe study the drivers of persistent insider trading profitability by examining the trades of insiders whose past trades have been profitable. We find that the current transactions of these persistently profitable (PP) insiders better predict firm performance than those of other insiders. The relative abnormal performance is more pronounced for trades of insiders who are managers rather than large shareholders or unaffiliated insiders and for trades in firms with weaker governance and greater information asymmetry. The trades of PP insiders also better predict earnings surprises, major corporate news, and analyst revisions. Collectively, these results indicate that PP insider transactions provide valid signals regarding future firm performance and that persistence in profitability is driven by informational advantages.
Effect of resin infiltration on the color and microhardness of bleached white‐spot lesions in bovine enamel (an in vitro study)
Authors: Horuztepe Sidika Aynur , Baseren Meserret 
Published: June 2017

AbstractObjectivesThe aim of this study was to investigate both the effect of resin infiltration on the color and microhardness of white spot lesions (WSLs) that treated with bleaching and to analyze the penetration of the infiltrant.Materials and MethodsIn each of 135 bovine enamel specimens, WSLs were produced. The samples were then randomly divided into three groups (n = 45): group I, bleached; group II, resin‐infiltrated; group III, bleached and resin‐infiltrated. The specimens were subjected to a pH‐cycling regime for four weeks. The color and microhardness were measured at the baseline, after production of WSLs, after the treatments. The color alteration (ΔE*) and the percentage of surface microhardness recovery (SMHR) were calculated. The penetration of the infiltrant was evaluated by scanning electron microscopy. Results were analyzed with analysis of variance, Shapiro–Wilk, Tukey's, Kruskal–Wallis and Conover–Dunn tests (P = .05).ResultsThe SMHR% in resin infiltration groups was significantly higher than that of the bleached group only (P < .05). Bleaching treatment prior to resin infiltration produced no significant change in the microhardness (P > .05). Using a bleaching treatment prior to resin infiltration produced significant color alteration (P < .05). The penetration of the resin infiltrant was deepest in‐group II.ConclusionsThe resin infiltration enhanced the microhardness of the WSLs regardless of whether or not a bleaching treatment was used. Using a bleaching treatment before resin infiltration resulted in color alteration, and it was also found to negatively influence the penetration of the infiltrant.

This review examines the complexity of these challenges, exploring the multiple levels of contextual factors that influence youth's well‐being as they experience adjudication. Using an ecological framework, this paper reviews findings on the individual socio‐demographic characteristics, as well as the micro, meso, exo, and macro factors that impact their development and functioning. Specific policy and practice implications are provided to address improving outcomes of youth in this population at each ecological level.
EXPLOITING CLOSED‐END FUND DISCOUNTS: A SYSTEMATIC EXAMINATION OF ALPHAS
Authors: Patro Dilip , Piccotti Louis R. , Wu Yangru 
Published: June 2017

AbstractWe systematically study the value of the information contained in closed‐end fund (CEF) premiums. We parametrically estimate CEF expected returns as a function of the history of CEF premiums, in addition to the current premium, and buy the quintile of funds with the highest expected returns and sell the quintile of funds with the lowest expected returns. The return on this portfolio suggests that previous studies, which examine the information in current premiums only, have understated the value of the information in premiums. Our strategy values the information in the history of CEF premiums at an annualized return of 18.2%.

Published: June 2017

SummaryWhile the impact of interpersonal discrimination on mental health is well established, its effects on physical health outcomes have not been fully elucidated. This study systematically reviewed the literature on the prospective association between interpersonal discrimination and markers of adiposity. Medline, Web of Science, Scopus, PsycInfo, SciELO, LILACS, Google Scholar, Capes/Brazil and ProQuest databases were used to retrieve relevant information in November 2016. The results from the 10 studies that met the inclusion criteria support an association between interpersonal self‐reported discrimination and the outcomes. In general, the most consistent findings were for weight and body mass index (BMI) among women, i.e. high levels of self‐reported discrimination were related to increased weight and BMI. Waist circumference (WC) showed a similar pattern of association with discrimination, in a positive direction, but an inverted U‐shaped association was also found. Despite a few inverse associations between discrimination and markers of adiposity, none of the associations were statistically significant. Overall, markers of adiposity were consistently associated with discrimination, mainly through direct and nonlinear associations. This review provides evidence that self‐reported discrimination can play an important role in weight, BMI and WC changes.
