Published: February 2015

AbstractThree primary factors affecting genetic patterns of marine species in the Northwestern Pacific Ocean have been proposed: isolation and population expansion during Pleistocene glacial cycles, ocean currents facilitating the gene flow, and the Yangtze River outflow imposing a physical barrier to gene flow. Here, we examined these factors affecting population structuring of the Asian paddle crab, Charybdis japonica, in the Yellow Sea, East China Sea, and adjacent areas. Genetic variation in nine populations of C. japonica (n = 169) was determined from partial mitochondrial cytochrome c oxidase subunit I sequences. Among the 14 haplotypes identified, a dominant haplotype H1 was present in all populations, and a relatively abundant localized haplotype H2 was found in four of the northern populations. Furthermore, the frequency of the common haplotype H1 decreased from south to north. A genetic discontinuity was detected in Haizhou Bay, which divided species into two groups (north group and south group). The lack of genetic structure in the south and north groups indicates high dispersal of C. japonica within groups. Local marine gyres in Haizhou Bay might be responsible for the divergence of the north and south groups. Our study highlights the importance of local marine gyres for influencing genetic structure in marine coastal species in the Northwestern Pacific, especially in species spawning inshore.

The type VI secretion system (T6SS) is a machine evolved by Gram-negative bacteria to deliver toxin effectors into target bacterial or eukaryotic cells. The T6SS is functionally and structurally similar to the contractile tail of theMyoviridaefamily of bacteriophages and can be viewed as a syringe anchored to the bacterial membrane by a transenvelope complex. The membrane complex is composed of three proteins: the TssM and TssL inner membrane components and the TssJ outer membrane lipoprotein. The TssM protein is central as it interacts with both TssL and TssJ, therefore linking the membranes. Using controlled trypsinolysis, a 32.4 kDa C-terminal fragment of enteroaggregativeEscherichia coliTssM (TssM32Ct) was purified. A nanobody obtained from llama immunization, nb25, exhibited subnanomolar affinity for TssM32Ct. Crystals of the TssM32Ct–nb25 complex were obtained and diffracted to 1.9 Å resolution. The crystals belonged to space groupP64, with unit-cell parametersa = b = 95.23,c= 172.95 Å. Molecular replacement with a model nanobody indicated the presence of a dimer of TssM32Ct–nb25 in the asymmetric unit.
A preliminary study on the usage of search assisting features when searching for a personal health task
Authors: Inthiran Anushia , Alhashmi Saadat M , Ahmed Pervaiz  K 
Published: February 2015

Purpose
– Current research topics in relation to health information searching focus on challenges faced by health consumers and domains used to perform the health search. Health consumers may not be capable of successfully searching for a health task due to limited medical knowledge. As such search assisting features provided on health domains are important in assisting health consumers during a search session. The purpose of this paper is to perform a preliminary exploratory research study to understand if search assisting features are visible to searchers and the usage of search assisting features when searching on a personal health task.

Design/methodology/approach
– A convenience sampling method in a university setting and an observational type study was used. MedlinePlus is used as the search domain for this research study. While participants of this research study were first time users of MedlinePlus, they were not first time medical searchers.

Findings
– Results of this research study indicate health consumers do not utilize search assisting features when searching for a personal health task. This is because health consumers are comfortable with their search skills. In other cases health consumers found the search assisting features irrelevant or had no confidence in the search assisting features presented. Key contributions of this research study indicate health consumers do not utilize search assisting features when searching for a personal health task. This is because health consumers are comfortable with their search skills. In other cases health consumers found the search assisting features irrelevant or had no confidence in the search assisting features presented.

Research limitations/implications
– Results of this research study has implications for health domain and human computer designers in relation to the development of specialized search assisting features and the placement of these features. Theoretical contributions indicate health searchers use search assisting features minimally when searching on a personal health task.

Originality/value
– Results of this research study indicate health consumers do not utilize search assisting features when searching for a personal health task. This is because health consumers are comfortable with their search skills. In other cases health consumers found the search assisting features irrelevant or had no confidence in the search assisting features presented.
Why do students use What’s App? – an exploratory study
Authors: Aharony Noa 
Published: February 2015

Purpose– This study focusses on What’s App, a mobile messaging service for smartphones, that was founded in 2009. The purpose of this study is to explore which factors may influence students’ satisfaction and duration of time, spent on What’s App.Design/methodology/approach– In order to answer this question it uses the Uses and Gratifications (U&G) approach (Katz, 1959), as well as the Big Five model (Costa and McCrae, 1992), and the Technology Acceptance Model (TAM) (Davis, 1989). The research was conducted in Israel and encompassed 111 information science (IS) students. Researchers used six questionnaires to gather data.Findings– The findings of this study shed light on a new technological platform: What’s App that has rarely been examined to date, and expands the U&G perspectives to new media. Findings confirm that the U&G paradigm, as well as personality characteristics and perceived enjoyment, effect What’s App satisfaction and duration, and highlight the importance of both the U&G approach and individual differences when exploring motivations underlying What’s App use.Originality/value– This study proposes a theoretical framework by combining the U&G approach, constructs from the “Big Five” model, and one variable from the TAM, to investigate the attitudes of What’s App users, and propose possible factors that may explain why certain individuals use What’s App.
Assessing the status of entrepreneurship education courses in higher learning institutions
Authors: Fulgence Katherine 
Published: February 2015

Purpose
– The purpose of this paper is to assess the status of entrepreneurship courses offered in education schools. It provides recommendations for how to address the existing challenges by developing entrepreneurship initiatives in education schools.

Design/methodology/approach
– A survey was circulated to the management of all education schools in Tanzania, respective entrepreneurship educators and graduates from these schools. Random sampling was used to select teachers who had graduated from education schools.

Findings
– The findings show that all education schools have an entrepreneurship module in the development studies course, which is mandatory for all students in first year. From 2008 to date, six education schools (31.6 per cent) have introduced stand-alone courses at undergraduate level reflecting entrepreneurship in their title and 68.4 per cent are planning to introduce entrepreneurship courses both at undergraduate and postgraduate level. Although entrepreneurship educators demonstrate subject specialty, they use traditional teaching and assessment techniques. The lack of books on entrepreneurship and the large number of students were cited as the main challenges affecting their role as subject facilitators.

Research limitations/implications
– The study was limited to education schools in higher education institutions. Similar studies in non-business disciplines need to be conducted to establish how entrepreneurship is developed among graduates of higher education institutions.

Practical implications
– The study recommends that the management of all education schools should be made aware of the need to provide courses in entrepreneurship, to integrate experiential learning and innovative techniques in the teaching and assessment processes and to involve students in extra-curriculum activities.

Originality/value
– This is the first study to be conducted in Tanzanian higher education institutions that focuses on the teaching of entrepreneurship to education school students.
Still focusing on the “essential 2:1”: exploring student attitudes to extra-curricular activities
Authors: Greenbank Paul 
Published: February 2015

Purpose
– In order to compete for positional advantage in the graduate labour market students need more than a good degree classification. The evidence suggests that participation in extra-curricular activities (ECAs) can have a significant influence on labour market outcomes. The purpose of this paper is to examine the extent to which undergraduates engage in ECAs during their studies and analyses the factors influencing their participation in such activities.

Design/methodology/approach
– This study is based on a sample of 21 undergraduates in the Business School at a “new” university. These students completed two questionnaires in their first year of study. These were followed-up by in-depth interviews which were carried out in their first and final year of study.

Findings
– The study found that many of these students were not participating in ECAs because they lacked an appreciation of the value of ECAs to graduate employers. The students were also influenced by social and peer norms, especially the fact that their peers were not engaging in ECAs. Finally, the students often exhibited an extrinsic locus of control and dependency which was not conducive to engagement in ECAs.

Research limitations/implications
– The generalisability of the findings may be seen as limited by the fact that the study is based on a relatively small sample of students from one university. This research, however, provides detailed insights into the factors influencing student participation in ECAs and adds new perspectives to this under-researched area.

Practical implications
– The paper concludes by suggesting a range of inter-related approaches that higher education institutions could adopt in order to improve student participation in ECAs. These include careers education at all stages of the students’ studies; the use of unfreezing techniques in conjunction with case studies; a more substantial role for personal tutors; and the development of an institutional habitus that encourages autonomy and agency.

Originality/value
– Despite the importance of ECAs to graduate employers there have been relatively few studies into the factors influencing undergraduate participation in such activities.
Becoming a graduate: the warranting of an emergent identity
Authors: Holmes Leonard M. 
Published: February 2015

Purpose– With expansion of higher education in most developed and developing economies, graduates constitute a large section of the workforce. However, even prior to the economic problems of the past few years, the transition from higher education into graduate employment has not been and is not straightforward. The purpose of this paper is to draw upon relational, social constructionist perspectives to examine such transition and early careers in terms of “emergent identity” trajectories. The “graduate identity” is considered in terms of the interaction between identity claim by the individual and the identity ascriptions by others.Design/methodology/approach– A model is presented, providing for five “modalities” of such emergent identity, whereby any particular individual may pass in varied trajectories. This is illustrated by three case examples of graduates, based on biographical interview data. The exploration is continued in terms of discussion of the discursive warranting of identity claims and ascriptions, enabling a reconsideration of the discourse of skills and attributes. Implications for research and practice are considered.Findings– The paper argues that the approach presented provides a cogent approach for conceptualising and for engaging in empirical investigation of the early career trajectories of individuals entering post-graduation employment. Such individuals may “formally” be graduates, but face the task of “becoming” graduates, i.e. gaining acceptance by significant others that they are “worthy” of being employed in “graduate jobs”. That task involves identity claim making, warranting their claim on the identity of a graduate.Research limitations/implications– The model and approach presented provide a framework for analysis of early-career trajectories of graduates, in a way that the dominant skills and attributes approach cannot. It contributes to other empirical studies based on qualitative, biographical research, by providing conceptual tools for the analysis of such studies.Practical implications– The paper provides a practical approach to help undergraduates and new graduates to enhance their prospects for gaining employment they consider desirable and appropriate. It enables staff who seek to support students to gain appropriate employment to develop practical strategies, unencumbered by flawed notion of “skills” and “attributes”.Social implications– Post-graduation employment continues to be a major policy issue for government, and a matter of considerable concern for students themselves and for their families. The approach presented promises considerable opportunity for addressing the critical issues faced.Originality/value– The paper elaborates the graduate identity approach, and provides empirical support for the claims made.
Towards an integrated academic assessment: closing employers’ expectations?
Authors: Lim Ngat-Chin 
Published: February 2015

Purpose– The purpose of this paper is to showcase that the integration of academic assessment with workplace performance appraisal practices can help to address the gap between graduate employability skills and employers’ requirements. Employability refers to learning of transferable skills.Design/methodology/approach– The integrated assessment criteria grid by which the quality of the assignments may be judged was developed and discussed with the students. Grades achieved by each assessment criterion are analysed and inferred as to whether students have learned the desired transferable skills.Findings– Such integration strengthens the theoretical argument on the importance of formative assessment as a way to nurture students’ learning. The transferable skills that students appeared to have learnt include “use of relevant data, meticulous, attention to details, structure & systems thinking, critical thinking and writing skill”.Research limitations/implications– Only one cohort of students is involved and their participation in the discussion is on a voluntary basis. The paper was not able to address students who did not appear to have learnt the transferable skills.Practical implications– Employers are more cognisant of the quality of the management students graduating from this university. The learning of transferable skills reflects creativity development, and this contributes to the theory of knowledge which emphasises the importance of developing creativity through education.Originality/value– This paper introduces a new form of formative assessment as a way to nurture students’ learning of transferable skills within a coursework assignment setting.
Service performance quality evaluation and satisfaction in a USA wine festivalscape
Authors: Bruwer Johan , Kelley Kathleen 
Published: February 2015

Purpose
– The purpose of this paper is to examine the links between perceived festival service performance quality, satisfaction, buying wine at the event, and the first-time/repeat tourist dynamic.

Design/methodology/approach
– The research was conducted on 368 attendees at a major wine festival in the northeast USA using intercept face-to-face interviews.

Findings
– The facility-related quality aspects are a stronger predictor of buying behaviour than activity-related aspects and amenities. A relationship between performance quality perception and satisfaction could not be found. 35-year and older repeat visitors are the highest yielding festival visitor group from a financial viewpoint. First-timers are far more short-term oriented than repeat visitors when making the final decision to attend the festival event.

Research limitations/implications
– It is very important to achieve a high degree of repeat festival attendance as this directly influenced the financial gains in selling more wine. The nature and types of activities offered at a festival must be cohesive with the theme of the event. The festival activities offered should be continually evaluated for signs of wear out, and renewed, or replaced if necessary.

Originality/value
– The research provides a new perspective to festivalscape knowledge in that it identifies the first-time and repeat visitor dynamic as a strong predictor of actual buying behaviour at a festival. The higher the proportion of repeat visitors, the higher the likelihood of (wine) buying.
Developing a high quality intercultural relationship: expatriates and their local host
Authors: van Bakel Marian , van Oudenhoven Jan Pieter , Gerritsen Marinel 
Published: February 2015

Purpose
– The qualitative study examines the development of purposely created interpersonal relationships in an intercultural context. Contact with a local host is a way of helping expatriates deal with the challenges of an international assignment. Since the quality of contact with the host is pivotal to benefit most from this experience, the purpose of this paper is to examine which factors influence contact quality.

Design/methodology/approach
– The authors conducted a case study analysis of 33 expatriates and ten accompanying partners who were put in touch with a local host, with whom they undertook a broad range of activities during a period of nine months.

Findings
– Nine factors influenced the development of the contact (similarities, motivation, benefits, anxiety, expectations, busy schedules, suboptimal timing, communication breakdown, and cultural differences). Key factors were similarities, motivation, and benefits.

Research limitations/implications
– While some of the factors (e.g. similarities) are predictable according to the Social Penetration Theory, four factors were uniquely applicable to purposely created relationships such as contact with a local host: motivation, expectations, anxiety, and suboptimal timing.

Practical implications
– The study provides suggestions that could stimulate the contact with a local host, making the intervention more valuable for organisations who wish to support their expatriates in this way.

Originality/value
– This longitudinal study is one of the first to examine in detail the process of development of purposely created interpersonal relationships in an intercultural context. Furthermore, the study is new because it also examines unsuccessful relationships.
The global financial crisis and migration: the experience of Irish graduates
Authors: Stephens Simon 
Published: February 2015

Purpose– The purpose of this paper is to identify a group of Irish graduates who decided to emigrate following the global financial crash of 2008. The paper explores how the economic crisis in Ireland (2008-2014) framed the experience of this group of migrants. Specifically, the paper examines the push/pull factors leading to migration; the experience of the graduate migrants in the host country; and decisions regarding repatriation.Design/methodology/approach– This paper adopts a qualitative approach to study the experiences of graduates. The paper utilises narrative structuring to provide an enhanced understanding of the migration experience of the graduates.Findings– The data collected during depth interviews indicates a mixed experience. There are a wide range of push/pull factors that result in migration. However, the range of push/pull factors that might result in repatriation are blurred by: personal experiences in the host country, changing family circumstances and the performance of the economy in Ireland.Practical implications– This research highlights complex patterns of graduate mobility which reflect the multifaceted push/pull factors shaping graduate movements. Economic conditions drive migration but they also frame the migrant experience in the host country and repatriation decisions.Originality/value– A review of the literature indicates that most of the empirical studies on the experience of graduates are quantitative. This paper argues other softer outcomes must also be studied to help fully understand the experiences of graduates.
Motivational mechanisms influencing error reporting among nurses
Authors: Russo Marcello , Buonocore Filomena , Ferrara Maria 
Published: February 2015

Purpose
– The purpose of this paper is to explore antecedents, namely reasons for/against error reporting, attitudes, subjective norms, and perceived control, of nurses’ intentions to report their errors at work.

Design/methodology/approach
– A structured equation model with cross-sectional data were estimated to test the hypotheses on a sample of 188 Italian nurses.

Findings
– Reasons for/against error reporting were associated with attitudes, subjective norms and perceived control. Further, reasons against were related to nurses’ intentions to report errors whereas reasons for error reporting were not. Lastly, perceived control was found to partially mediate the effects of reasons against error reporting on nurses’ intentions to act.

Research limitations/implications
– Self-report data were collected at one point in time.

Practical implications
– This study offers recommendations to healthcare managers on what factors may encourage nurses to report their errors.

Social implications
– Lack of error reporting prevents timely interventions. The study contributes to documenting motivations that can persuade or dissuade nurses in this important decision.

Originality/value
– This study extends prior research on error reporting that lacks a strong theoretical foundation by drawing on behavioral reasoning theory.
