Expression and distribution of Trophoblast Glycoprotein in the mouse retina
Authors: Wakeham Colin M , Ren Gaoying , Morgans Catherine W 
Published: March 2019

AbstractWe recently identified the leucine-rich repeat adhesion protein, trophoblast glycoprotein (TPBG), as a novel PKCα-dependent phosphoprotein in retinal rod bipolar cells (RBCs). Since TPBG has not been thoroughly examined in the retina, this study characterizes the localization and expression patterns of TPBG in the developing and adult mouse retina using two antibodies, one against the N-terminal, leucine-rich domain and the other against the C-terminal PDZ-interacting motif. Both antibodies labeled dendrites and synaptic terminals of RBCs, as well as the cell bodies and dendrites of an uncharacterized class of amacrine cell. In transfected HEK293 cells, TPBG was localized to the plasma membrane and intracellular membranes and was associated with the tips of thin filopodia-like membrane projections. TPBG immunofluorescence in RBCs detected with the C-terminal antibody was strongly dependent on the activity state of the adult retina, with less labeling in dark-adapted compared to light-adapted retina, and less labeling in light-adapted PKCα knockout and TRPM1 knockout retinas compared to wild type, despite no change in total TPBG detected by immunoblotting. These results suggest that the C-terminal epitope is blocked in the dark-adapted and knockout retinas compared to light-adapted wild type retinas, possibly through interaction with a PDZ domain protein. During development, TPBG expression increases dramatically just prior to eye opening with a time course closely correlated with that of TRPM1 expression. In the retina, leucine-rich repeat proteins like TPBG have been implicated in the development and maintenance of functional bipolar cell synapses, and TPBG may play a similar role in RBCs.
Consuming material authenticity in the age of digital reproduction
Authors: Goulding Christina , Derbaix Maud 
Published: March 2019

PurposeThis paper aims to examine how and why an “old” technology and mode of consumption – vinyl records, which should have become obsolete – has managed not only to survive but also revive in the face of supposedly cheaper and superior digital formats.Design/methodology/approachThe authors used constructivist grounded theory (CGT), a methodology rooted in pragmatism. The authors acknowledge the primacy of relational, conversational and social practices as the source of individual and social life, and that all knowledge is local and the product of negotiation between people within a given context and time frame. In terms of data, the authors draw on the extensive use of memos and participatory observation at the oldest vinyl record store in the UK. The authors also draw on interviews with the store owner and workers and in-depth interviews with vinyl enthusiasts.FindingsThe authors argue that authenticity is not a fixed and static concept but has fluid and porous boundaries that can be experienced by individuals in different situations. The findings center around three experiences of authenticity – staged authenticity, interpersonal authenticity and intrapersonal/existential authenticity.Research limitations/implicationsThis research is limited to a specific market, typical of old or second-hand vinyl consumption. Future research would benefit from broadening the sample to include new consumers and female enthusiasts of both old and new vinyl.Practical implicationsThe paper has implications for consumer service and personal selling relationships.Originality/valueOriginality lies in theoretically positioning the phenomenon within a conceptual framework of authenticity. In particular, the authors shed light on the role that authenticity plays in the experiences of vinyl music consumption amongst buyers and sellers in a store that has a long established heritage. The authors find that vinyl in the age of digital reproduction retains and maintains a number of qualities that are missing from allegedly superior forms of musical reproduction. The authors further maintain that as it has aged, original vinyl has taken on greater power and meaning, and now that it is out of the realm of mass production/consumption, it has opened up a deeper more authentic interaction between human beings and technology. This deeper interaction goes beyond the immediate experience with the object itself and extends to the sensorial, the social and the personal.
Rethinking some of the rethinking of partial least squares
Authors: Hair Joseph F. , Sarstedt Marko , Ringle Christian M. 
Published: March 2019

PurposePartial least squares structural equation modeling (PLS-SEM) is an important statistical technique in the toolbox of methods that researchers in marketing and other social sciences disciplines frequently use in their empirical analyses. The purpose of this paper is to shed light on several misconceptions that have emerged as a result of the proposed “new guidelines” for PLS-SEM. The authors discuss various aspects related to current debates on when or when not to use PLS-SEM, and which model evaluation metrics to apply. In addition, this paper summarizes several important methodological extensions of PLS-SEM researchers can use to improve the quality of their analyses, results and findings.Design/methodology/approachThe paper merges literature from various disciplines, including marketing, strategic management, information systems, accounting and statistics, to present a state-of-the-art review of PLS-SEM. Based on these findings, the paper offers a point of orientation on how to consider and apply these latest developments when executing or assessing PLS-SEM-based research.FindingsThis paper offers guidance regarding situations that favor the use of PLS-SEM and discusses the need to consider certain model evaluation metrics. It also summarizes how to deal with endogeneity in PLS-SEM, and critically comments on the recent proposal to adjust PLS-SEM estimates to mimic common factor models that are the foundation of covariance-based SEM. Finally, this paper opposes characterizing common concepts and practices of PLS-SEM as “out-of-date” without providing well-substantiated alternatives and solutions.Research limitations/implicationsThe paper paves the way for future discussions and suggests a way forward to reach consensus regarding situations that favor PLS-SEM use and its application.Practical implicationsThis paper offers guidance on how to consider the latest methodological developments when executing or assessing PLS-SEM-based research.Originality/valueThis paper complements recently proposed “new guidelines” with the aim of offering a counter perspective on some strong claims made in the latest literature on PLS-SEM. It also clarifies some misconceptions regarding the application of PLS-SEM.
Consumption-oriented engagement in social network sites
Authors: Ho Hillbun , Ito Kenichi 
Published: March 2019

Purpose
Mounting empirical evidence shows that engagement in social network sites (SNSs) could have a negative impact on users’ personal well-being. However, studies of the undesirable effects of SNS use have not examined SNSs as a channel for users to share consumption information and experiences. To extend prior research, this study aims to examine the impact of consumption-oriented engagement (COE) in SNSs on young adult consumers’ personal well-being in terms of anxiety and self-esteem, as well as excessive spending.

Design/methodology/approach
Surveys were the primary means of data collection from a sample of young college students (N = 900). Moderated hierarchical regression was used to test the hypotheses.

Findings
COE is positively associated with anxiety and excessive spending and negatively associated with self-esteem. Social comparison mediates these relationships, and individuals’ materialistic values moderate the mediation.

Research limitations/implications
This study demonstrates the psychological and behavioral outcomes of consumer socialization via digital media among young adult consumers. It introduces and empirically validates social comparison as a theoretical explanation for the effects of COE. In addition, it validates materialistic values as a personal trait that moderates the effects of COE.

Practical implications
The study validates COE as a key precursor to the well-being of young adult users of SNSs and social comparison as the mediator. With this understanding, public policies can be designed to mitigate the root cause of the negative impact of SNS use.

Originality/value
Findings shed light on the negative repercussions of engagement in SNSs in the consumption domain and provide an impetus for educators, researchers and policymakers to make further efforts to gain a thorough understanding of the pitfalls of social media use.

Published: March 2019

PurposeThe purpose of this paper is to develop a competency dictionary and model for contractual workers of the steel manufacturing sector of India.Design/methodology/approachIn-depth interviews with 30 supervisors and behavioral events interviews (BEIs) with 40 contractual workers were conducted to identify and validate the competencies of the contractual workers.FindingsThe competencies identified are arranged according to the similarity and dissimilarity between it under three broad categories of competencies, i.e., knowledge, skills and attitudes. These categories are used to develop a competency dictionary which has behavioral indicators, and a framework that can be used to map and evaluate the competencies.Practical implicationsThe competency dictionary and the framework developed in the present study will assist human resource practitioners in implementing competency-based human resource processes such as recruitment and selection, training and development and performance management for the contractual workers in the manufacturing sector.Originality/valueThe present study is among the few empirical studies that provide a competency dictionary and a framework of contractual workers in the manufacturing sector of India.
On operations and marketing in microfinance-backed enterprises
Authors: Nilakantan Rahul , Iyengar Deepak , Rao Shashank 
Published: March 2019

PurposeFinancial inclusion remains one of the most promising avenues to bring about development for the poorest segments of society. A substantial body of work has looked into financial inclusion, especially in terms of microfinance, but much of it has been anecdotal and case-based. There is little scholarship that broadly investigates how microfinance-funded businesses choose to use the loans, especially given the ever-present competition for resources that such businesses face regarding which investment priority to pursue. In addition, the efficacy of these investments in terms of subsequent profitability remains unexplored, and so too does the influence of the entrepreneur’s embeddedness in the local community. The paper aims to discuss these issues.Design/methodology/approachThis study reports the results from a field investigation of 927 women entrepreneurs who received a microfinance loan from a leading Indian microfinance institution. Logit and OLS regression models are employed in a moderation analysis by way of hierarchical regression.FindingsResults indicate that access to microfinance increases the likelihood that the enterprise invests in marketing infrastructure and operational scale. In addition, structural embeddedness has a weakening effect on this relationship for operational scale while having a strengthening effect on the relationship for marketing infrastructure. Finally, operational scale is related to enterprise profitability, while marketing infrastructure is not. These findings suggest that embeddedness in the community is associated with the entrepreneur making sub-optimal choices regarding microfinance utilization.Originality/valueTo our knowledge, this is the first study to investigate the simultaneous marketing and operational impacts of microfinance access. It is also the first study to relate these measures to the profitability of the enterprise, especially in the context of structural embeddedness in the network.
Explaining India’s current account deficit: a time series perspective
Authors: Behera Harendra Kumar , Yadav Inder Sekhar 
Published: March 2019

Purpose
The purpose of this paper is to examine the issue of high current account deficit (CAD) from various perspectives focussing its behaviour, financing pattern and sustainability for India.

Design/methodology/approach
To begin with the trends, composition and dynamics of CAD for India are analysed. Next, the influence of capital flows on current account is investigated using Granger non-causality test proposed by Toda and Yamamoto (1995) between current account balance (CAB) to GDP ratio and financial account balance to GDP ratio. Also, the sustainability of India’s current account is examined using different econometrics techniques. In particular, Husted’s (1992), Johansen’s cointegration and vector error correction model (VECM) is applied along with conducting unit root and structural break tests wherever applicable. Further, long-run and short-run determinants of the CAB are estimated using Johansen’s VECM.

Findings
The study found that the widening of CAD is due to fall in household financial savings and corporate investments. Also, it was found that a large part of India’s CAD has been financed by FDI and portfolio investments which are partly replaced by short-term volatile flows. The unit root and cointegration tests indicate a sustainable current account for India. Further, econometric analysis reveals that India’s current account is driven by fiscal deficit, terms of trade growth, inflation, real deposit rate, trade openness, relative income growth and the age dependency factor.

Practical implications
Since India’s CAD has widened and is expected to widen primarily due to rise in gold and oil imports, policy makers should focus on achieving phenomenal export growth so that a sustainable current account is maintained. Also, with rising working-age and skilled population, India should focus more on high-value product exports rather than low-value manufactured items. Further, on the structural side it is important to correct fiscal deficit as it is one of the important factors contributing to large CAD.

Originality/value
The paper is an important empirical contribution towards explaining India’s CAD over time using latest and comprehensive data and econometric models.
Functional domains of business incubators for refugee entrepreneurs
Authors: Harima Aki , Freudenberg Julia , Halberstadt Jantje 
Published: March 2019

Purpose
The purpose of this paper is to conceptualize business incubators and their support for entrepreneurial refugees. While the number of initiatives supporting refugees’ entrepreneurial activities has increased in recent years, we still know little about how they differ from other types of business incubators.

Design/methodology/approach
This case study investigates a business incubator in Hamburg, Germany, targeting enterprising refugees. For this paper, 14 in-depth interviews with program participants and incubation managers were conducted.

Findings
This paper inductively derives five functional domains of refugee business incubators: providing structured entrepreneurial knowledge; alleviating anxiety related to institutional differences; guiding through the process at the incubator and motivating participants; understanding and tapping into social capital in the host country; and providing soft support concerning personal matters. The findings show that business incubators could and possibly should address specific needs of refugees and that there is much room for improvement. This study suggests that the five domains listed above represent key characteristics that distinguish refugee business incubators from traditional business incubators.

Practical implications
This paper offers valuable practical insights for refugee business incubators, which need to consider and develop functional domains listed above. Because these kinds of incubators are a fairly recent phenomenon, there is a general lack of and need for blueprints. The findings of this paper suggest that business incubators could integrate and support entrepreneurial refugees provided that they consider the five functional domains identified here. The findings also provide evidence that entrepreneurship can be a possible means of vocational integration for refugees and one way of institutions and policy-makers in host country seeking to support refugees’ entrepreneurial activities, for example, by developing or subsidizing business incubators targeting refugees.

Originality/value
This paper’s contributions are twofold. First, this paper addresses a gap in the literature on refugee entrepreneurship by providing insights concerning the important role of support institutions. Second, this paper conceptualizes business incubators for enterprising refugees as a distinctive type of business incubators. This paper has, however, some limitations. Because it only considered a relatively small number of refugee entrepreneurs, it is difficult to generalize the findings. The cross-cultural setting of the empirical study, with its potential for linguistic and cultural misunderstandings, may have affected the results.
Strategic investment acquisitions performance in UK firms: the impact of managerial overconfidence
Authors: Adel Nour , Alkaraan Fadi 
Published: March 2019

PurposeThis paper focuses on the influence of overconfident managers on strategic investment acquisitions performance, by investigating the influence of key contextual factors on acquirers’ returns of UK domestic and cross-border acquisitions during the period 2000-2009. In this study, particular attention has been paid to management attributes (frequent acquirers vs non-frequent acquirers); method of payment (cash vs non-cash deals); the geographic scope (domestic vs cross-border deals); the type of the target (public vs private); the industry scope; and the relative size.Design/methodology/approachAn event study is used to analyse domestic and cross-border acquisitions. The market model is used for estimating the acquirers’ abnormal returns of 1,133 domestic and cross-border acquisitions by UK firms between 1 January 2000 and 31 December 2009.FindingsThe findings reveal that acquirers with domestic targets have higher returns than cross-border targets. Infrequent acquirers generate higher returns from domestic and cross-border acquisitions than frequent acquirers. Further, acquirers that acquire domestic targets from different industrial sectors produce higher returns than acquirers with targets from the same sector. Acquirers with cash deals, private targets and high book-to-market ratio generate significant returns compared to acquirers with non-cash deals, low book-to-market ratio and public targets and that for domestic and cross-border deals. These results suggest that UK domestic and cross-border acquisitions are partially shaped by overconfident managers.Research limitations/implicationsThe study has a number of limitations, including the use of the market model, the data-collection process and the limited number of contextual factors. Future research may examine a number of avenues related to the current study, including incorporating the acquiring firms’ financial characteristics.Practical implicationsThe study provides a better understanding of the influence of contextual factors on the success and failure of strategic investment projects such as acquisitions. Results of post-acquisitions performance in UK firms show how estimation of value can be distracted at the pre-acquisition stage because of overconfident managers.Originality/valueResults of post-acquisitions performance in UK firms show how estimation of value can be distracted at the pre-acquisition stage because of overconfident managers.
How Facebook influences non-professional investors’ affective reactions and judgments
Authors: Farkas Maia , Keshk Walied 
Published: March 2019

PurposeThe use of social networking websites by companies to disclose corporate news and by investors to collect information for investment purposes is increasing rapidly. However, the role of investors’ affective reactions to corporate disclosures on social networking websites is under-researched. This paper aims to examine how the disclosure platform (disclosing news on a company’s Facebook Web page or the corporate investor relations Web page) and news valence (positive or negative) jointly influence investors’ affective reactions to corporate news and stock price change judgments.Design/methodology/approachThe authors conduct an experimental study using 364 participants from Amazon’s Mechanical Turk website as a proxy for reasonably informed investors.FindingsResults show that the disclosure platform influences investors’ affective reactions and stock price change judgments when the corporate news is negative, but not when the corporate news is positive. In addition, investors’ affective reactions mediate the influence of the disclosure platform on investors’ stock price change judgments when the corporate news is negative rather than positive.Originality/valueThis paper extends the theory on affective reactions to a social networking context by showing that differences in disclosure platforms and news valence influence investors’ affective reactions to corporate news. In addition, the study’s theory and findings have significant implications for researchers, company managers and public relations specialists, capital market participants, regulators and investor education organizations and users of social networking websites.
Teacher education and multicultural courses in North Carolina
Authors: Williams III John Andrew , Glass Tehia Starker 
Published: March 2019

PurposeTeacher effectiveness in diverse school environments depends highly on the multicultural education courses provided by Educator Preparation Programs (EPP). Research measuring new teachers’ (i.e. teachers having 0-3 years of teaching experience) effectiveness as a result of EPPs’ multicultural education courses is limited. The purpose of this study was to examine if any association occurred between the number of multicultural courses offered to pre-service teacher candidates by EPPs and their graduates rating of effectiveness, as it pertains to creating a culturally diverse classroom environment.Design/methodology/approachUsing data from the North Carolina Department of Public Instruction (NCDPI) and public EPPs course catalogs for North Carolina, this descriptive study investigates multicultural education course offerings and recent teacher graduate data for North Carolina for 2015, as it pertains to creating culturally diverse learning environments for students of color.FindingsThe results indicate that multiple EPPs in North Carolina are not providing multicultural courses for their pre-service teachers, and that novice teachers in North Carolina are lacking the ability to produce diverse learning environments for students of color at a high capacity as defined by the North Carolina Teacher Effectiveness definition.Research limitations/implicationsData were retrieved from 2015. In the current year, EPPs could have boosted their offerings of multicultural courses since that time.Social implicationsIt is anticipated that the lack course offerings by EPPs will directly reflect new teachers’ ability to create respectful learning environment for students of color, suggesting that EPPs may be counterproductive towards teacher candidates’ understanding of race in the classroom.Originality/valueThis study’s originality exists in its ability to begin to connect new teachers’ productivity with regards for promoting diversity or multiculturalism and the multicultural courses offered by EPPs.
