Habitat affinity and density-dependent movement as indicators of fish habitat restoration efficacy
Authors: Polivka Carlos M. 
Published: July 2019

AbstractConceptual and methodological tools from behavioral ecology can inform studies of habitat quality and their potential for evaluating habitat restoration in conservation efforts is explored here. Such approaches provide mechanistic detail in understanding the relationship between organisms and their habitats and are thus more informative than correlations between density and habitat characteristics. Several Pacific salmon species have been the target of habitat restoration efforts for the past 2-3 decades, but most post-restoration effectiveness studies have been limited to correlative data described above. In mark-recapture assays from four different study years, the affinity of sub-yearling Chinook salmon (Oncorhynchus tschawytscha) and steelhead (O. mykiss) for stream pools restored with or created by engineered log structures was greater than that for pools without restoration, though with high interannual variability. From corresponding distribution and density data, it was clear that habitat affinity data are not always concordant with single observations of density. The same was true of the correlation between either affinity or density and physical characteristics of pools, although depth and current velocity had some explanatory power for both responses in Chinook. Movement into pools by Chinook during the assays indicated that restored pools can support more immigrants at a given density than can unrestored pools; however no such pattern emerged for steelhead. Variation among individuals in body condition has implications for population-wide fitness, and such low variation was correlated with stronger affinity for pools in Chinook regardless of restoration status. This suggests that pools may mediate habitat-related trade-offs and that restoring them might have a positive effect on fitness. Thus affinity, immigration, and condition data give much-needed mechanistic indication of habitat selection for restored habitat via an apparent capacity increase and those potential fitness benefits. This is stronger support for restoration effectiveness than density differences alone because density data 1) may simply indicate redistribution of fish from poor to good habitats and 2) are not adequate to show correlations between restoration and positive change in traits correlated with fitness.

AbstractUnlike other bacterial ClpP systems, mycobacterial ClpP1P2 complex is essential for mycobacterial survival. The functional details of Mycobacterium tuberculosis (Mtb) ClpP1P2 remains largely elusive and selectively targeting ClpP of different species is a big challenge. In this work, cediranib was demonstrated to significantly decrease the activity of MtbClpP1P2. By solving the crystal structure of cediranib-bound MtbClpP1P2, we found that cediranib dysregulates MtbClpP1P2 by interfering with handle domain of the equatorial region of MtbClpP1, indicating that the inter-ring dynamics are crucial for its function. This finding provides direct evidence for the notion that a conformational switch in the equatorial handle domain is essential for ClpP activity. We also present biochemical data to interpret the distinct interaction pattern and inhibitory properties of cediranib toward MtbClpP1P2. These results suggest that the variable handle domain region is responsible for the species-selectivity of cediranib, which suggests the equatorial handle domain as a potential region for screening pathogen-specific ClpP inhibitors.

AbstractPandemic influenza A virus (IAV) remains a significant threat to global health. Preparedness relies primarily upon a single class of neuraminidase (NA) targeted antivirals, against which resistance is steadily growing. The M2 proton channel is an alternative clinically proven antiviral target, yet a near-ubiquitous S31N polymorphism in M2 evokes resistance to licensed adamantane drugs. Hence, inhibitors capable of targeting N31 containing M2 (M2-N31) are highly desirable.Rationalin silicodesign andin vitroscreens delineated compounds favouring either lumenal or peripheral M2 binding, yielding effective M2-N31 inhibitors in both cases. Hits included adamantanes as well as novel compounds, with some showing low micromolar potency versus pandemic “swine” H1N1 influenza (Eng195) in culture. Interestingly, a published adamantane-based M2-N31 inhibitor rapidly selected a resistant V27A polymorphism (M2-A27/N31), whereas this was not the case for non-adamantane compounds. Nevertheless, combinations of adamantanes and novel compounds achieved synergistic antiviral effects, and the latter synergised with the neuraminidase inhibitor (NAi), Zanamivir. Thus, site-directed drug combinations show potential to rejuvenate M2 as an antiviral target whilst reducing the risk of drug resistance.
Primate hippocampus size and organization are predicted by sociality but not diet

Published: July 2019

AbstractThe hippocampus is well known for its roles in spatial navigation and memory, but it is organized into regions that have different connections and functional specializations. Notably, the region CA2 has a role in social and not spatial cognition, as is the case for the regions CA1 and CA3 that surround it. Here we investigated the evolution of the hippocampus in terms of its size and organization in relation to the evolution of social and ecological variables in primates, namely home range, diet and different measures of group size. We found that the volumes within the whole cornu ammonis coevolve with group size, while only the volume of CA1 and subiculum can also be predicted by home range. On the other hand, diet, expressed as a shift from folivory toward frugivory, was shown to not be related to hippocampal volume. Interestingly, CA2 was shown to exhibit phylogenetic signal only against certain measures of group size but not with ecological factors. We also found that sex differences in the hippocampus are related to body size sex dimorphism. This is in line with reports of sex differences in hippocampal volume in non-primates that are related to social structure and sex differences in behaviour. Our findings support the notion that in primates, the hippocampus is a mosaic structure evolving in line with social pressures, where certain subsections evolve in line with spatial ability too.
The moderating role of tenure on the effects of job insecurity and employability on turnover intentions and absenteeism
Authors: León Federico R. , Morales Oswaldo 
Published: July 2019

PurposeThe purpose of this paper is to provide evidence on the role of tenure as a moderator of the effects of job insecurity (JI) and employability on turnover intentions and absenteeism and will demonstrate its importance in personnel research and theorization.Design/methodology/approachData from a sample of client service representatives of a Peruvian call centre (n=268) were analysed. Tests of hypotheses targeted the intact group as a whole and divided into short (3–10 months), medium (11–14 months) and long job tenure groups (15–37 months).FindingsResults of general linear models revealed that the effects of JI on turnover intention observed in the intact group were aligned with those seen within each of the tenure groups. However, this was not the case for the effects of JI on absenteeism or the effects of employability on turnover intention and absenteeism. A comparison of results of various regression models indicated that the effects of JI and employability on absenteeism differed in meaningful ways across the intact group and the tenure groups.Research limitations/implicationsThe evidence does not reveal whether the observed differences stem from dynamic personnel selection processes or whether they express different relationships between the variables at various stages of an employee’s trajectory in an organization.Practical implicationsHuman resource managers at call centres will be stimulated to re-evaluate the costs and benefits of promoting tenure, and journal editors will have to consider requesting the inclusion of tenure as a variable in studies focussing on organizations with high turnover.Originality/valueThis study is the first to prove that the effects of JI and employability on turnover intention and absenteeism vary across job tenure levels. It also shows the importance of addressing tenure in personnel research and theorization.
Effect of halal awareness, halal logo and attitude on foreign consumers’ purchase intention
Authors: Bashir Abdalla Mohamed 
Published: July 2019

Purpose
The purpose of this paper is to determine the factors that affect foreign consumers’ purchase intention towards purchasing halal food products in South Africa. These factors are halal awareness, halal logo and attitude, which are important factors in affecting the intention of consumers.

Design/methodology/approach
Data were collected via a self-questionnaire with a sample of 230 foreign consumers. For analysing these data, a structural equation modelling technique was used in this study.

Findings
Based on the study’s results, all factors significantly influence foreign consumers’ intention towards purchasing halal food products and, subsequently, their buying behaviour. Interestingly, the study found that attitudes and halal awareness of non-Muslim consumers are very high compared with those of the Muslim consumers. Although the study addressed halal food consumers, most of the respondents participated in the study were non-Muslims and the majority of them were Christians.

Research limitations/implications
The respondents were only limited to the Cape Town city in South Africa, and the focus was only on five variables related to halal food consumers, namely, halal awareness halal logo, attitude, purchase intention and buying behaviour.

Social implications
This study can be used to develop halal food products to attract both Muslim and non-Muslim consumers, who are foreigners to a particular country.

Originality/value
This study is one of the first studies seeking to determine the factors that affect foreign consumers with regard to the purchase of halal food products in South Africa. It is regarded one of the first attempts to determine halal awareness, halal logo and attitude and how purchase intention and buying behaviour can be influenced.

Published: July 2019

PurposeThe purpose of this paper is to examine urban households’ willingness to pay (WTP) for milk safety and to analyze the factors affecting WTP premiums using data obtained from surveys conducted in Samsun and Trabzon provinces, Turkey.Design/methodology/approachContingent valuation and censoring methods including the error-dependent bivariate Heckman SS model were used for estimating WTP for milk safety and its effective factors, respectively.FindingsThe study indicates that 68 percent of the households were willing to pay 0.35 per liter for improving the safety of milk. The model results show that satisfaction with food safety standards, being married and full-time employment have statistically significant positive effects on the WTP for ISO-certified milk. However, purchasing milk from farmers or open-air markets, age, having a child six-year old or younger, and high school or higher education have statistically significant negative effects on the WTP for ISO-certified milk.Research limitations/implicationsThe main limitation of the current study is that only urban consumers’ WTP and effective factors for milk safety were examined in two provinces of Turkey.Practical implicationsMore rigorous implementations of food safety standards, traceability systems and effective educational campaigns could promote households’ food safety awareness and increase their demand for milk safety.Social implicationsKnowing what factors are involved in consumer WTP is extremely important for decision makers to create new social policies in the region or country.Originality/valueA similar study has not been conducted in Turkey. The novelty of this study is the specification and robust estimation of three different but competing models to reveal the wide range of WTP amounts for safe milk.
A novel variant of the H-Φ field formulation for magnetostatic and eddy current problems
Authors: Smajic Jasmin 
Published: July 2019

Purpose
The paper presents a new variant of the H-Φ field formulation for solving 3-D magnetostatic and frequency domain eddy current problems. The suggested formulation uses the vector and scalar tetrahedral elements within conducting and non-conducting domains, respectively. The presented numerical method is capable of solving multiply connected regions and eliminates the need for computing the source current density and the source magnetic field before the actual magnetostatic and eddy current simulations. The obtained magnetostatic results are verified by comparison against the corresponding results of the standard stationary current distribution analysis combined with the Biot-Savart integration. The accuracy of the eddy current results is demonstrated by comparison against the classical A-A-f approach in frequency domain.

Design/methodology/approach
The theory and implementation of the new H-Φ magnetostatic and eddy current solver is presented in detail. The method delivers reliable results without the need to compute the source current density and source magnetic field before the actual simulation.

Findings
The proposed H-Φ produce radically smaller and considerably better conditioned equation systems than the alternative A-A approach, which usually requires the unphysical regularization in terms of a low electric conductivity value within the nonconductive domain.

Originality/value
The presented numerical method is capable of solving multiply connected regions and eliminates the need for computing the source current density and the source magnetic field before the actual magnetostatic and eddy current simulations.
Are high-performance work systems (HPWS) appreciated by everyone? The role of management position and gender on the relationship between HPWS and affective commitment
Authors: Andersén Jim , Andersén Annelie 
Published: July 2019

PurposeAlthough most studies on HPWS focus on various firm-level outcomes, there has been an increasing interest in how employees are affected by HPWS. However, most of these studies use social exchange theory and, based on an idea of reciprocal exchange, implicitly assume that all employees become more affectively committed to organizations using HPWS. Based on social identity theory, the authors argue that management position and gender likely influence how individuals respond to HPWS. Thus, the purpose of this paper is to examine how HPWS affects AC among managers, subordinates, men and women.Design/methodology/approachHierarchical linear model analysis of 356 employees in 26 Swedish small- and medium-sized manufacturing companies.FindingsIn the sample examined, managers and women show increased affective commitment (AC) in organizations using HPWS. For men with non-managerial positions, the results indicate a reversed relationship, i.e. HPWS could actually reduce AC.Originality/valueThe findings indicate the need to consider individual differences when examining the effect of HPWS, and highlight the usefulness of relational-oriented theories when studying the employee outcomes of HRM-systems.

Published: July 2019

PurposeThis paper aims to examine how a collaborative narrative inquiry focused on cultivating critical English Language Arts (ELA) pedagogies supported teacher agency, or “the capacity of actors to critically shape their own responsiveness to problematic situations” (Emirbayer and Mische, 1998, p. 971).Design/methodology/approachSituated in a semester-long inquiry group, eight k-16 educators used narrative inquiry processes (Clandinin, 1992) to write and collectively analyze (Ezzy, 2002) stories describing personal experiences that brought them to critical ELA pedagogies. They engaged in three levels of analysis across the eight narratives, including open coding, thematic identification, and identification of how the narrative inquiry impacted their classroom practices.FindingsAcross the narratives, the authors identify what aspects of the ELA reading, writing and languaging curriculum emerged as problematic; situate themselves in systems of oppression and privilege; and examine how processes of critical narrative inquiry contributed to their capacities to respond to these issues.Research limitations/implicationsCollaborative narrative inquiry between teachers and teacher educators (Sjostrom and McCoyne, 2017) can be a powerful method to cultivate critical pedagogies.Practical implicationsTeachers across grade levels, schools, disciplines and backgrounds can collectively organize to cultivate critical ELA pedagogies.Originality/valueAlthough coordinated opportunities to engage in critical inquiry work across k-16 contexts are rare, the authors believe that the knowledge, skills and confidence they gained through this professional inquiry sensitized them to oppressive curricular norms and expanded their repertoires of resistance.
From emotional labor to customer loyalty in hospitality
Authors: Wang Chung-Jen 
Published: July 2019

PurposeThe purpose of this study was based on the job demands -resources model (Bakker et al., 2004) and conservation of resources theory (Hobfoll, 1989) by using three levels of variables, namely, company (i.e., perceived organizational support), department (i.e., abusive supervision), and employee (i.e., deep acting, surface acting, and self-efficacy) levels, to investigate its interactions with contextual influences on service quality and its linkage with customer loyalty.Design/methodology/approachA three-level hierarchical linear model was examined in research settings by using a dyadic data set of 1,082 service employees and customers in international tourist hotels.FindingsFindings revealed that deep acting relates positively to service quality, surface acting relates negatively to service quality, and service quality relates positively to customer loyalty. For the three-level interactions, the positive relationship between deep acting and service quality was strengthened by perceived organizational support (POS) and self-efficacy but weakened by abusive supervision. By contrast, the negative relationship between surface acting and service quality was mitigated by POS and self-efficacy but exacerbated by abusive supervision.Originality/valueGiven the importance of emotional labor research in the hospitality industry, the current study contributes to the areas of service quality and customer loyalty and suggests future directions for hospitality research.
FGM in Egypt between socio-cultural barriers and lack of political will
Authors: Khodary Yasmin , Hamdy Nehal 
Published: July 2019

Purpose
This study aims to detect the main factors impeding the anti-female genital mutilation (FGM) efforts in Egypt post the January 25 revolution, with a special focus on the era of president El-Sisi. The purpose of this paper is to explain the reasons behind the continuation of violence against women in Egypt, namely, FGM, in light of the patriarchal structures and the state willingness to address that challenge.

Design/methodology/approach
The study utilizes a qualitative methodology. The study embarks on in-depth semi-structured interviews with 23 participants who experienced FGM and nine key informants from medical, religious, political and civil society backgrounds, including a professor of pathology, a gynecologist, a diplomatic researcher in Al-Azhar, three members of parliament, a representative of the Ministry of Population, the reporter of the National Council for Women and a representative of Nazra non-governmental organization for feminist studies in Egypt.

Findings
The findings reveal that FGM remains prevalent not only due to the persisting socio-cultural context that continues to embrace and reproduces gender inequalities, but also because of the insufficient political will to combat FGM and enforce the required laws.

Social implications
FGM is considered one form of gender inequality perpetuated by social, cultural and economic structures. It is recognized internationally as a crime and a violation against women’s rights as per the Universal Declaration of Human Rights, the Convention on the Elimination of All Forms of Discrimination against Women, the Convention on the Rights of the Child, etc. Although the Egyptian Government passed laws banning the practice of FGM, it continues to form a challenging problem to social workers, women activists, human rights groups and public health officials.

Originality/value
Little work has been done to investigate FGM post the January 25 revolution in Egypt and identify the main factors impeding the anti-FGM efforts in Egypt. This work fills this gap and concludes with some lessons learnt to fight FGM and improve the anti-FGM efforts.
Leveraging learning analytics for student reflection and course evaluation
Authors: Ozdemir Devrim , Opseth Heather M. , Taylor Holland 
Published: July 2019

Purpose
The purpose of this paper is to demonstrate a process of faculty utilization of learning analytics by evaluating students’ course objective achievement results to enable student reflection, student remediation and faculty curriculum evaluation.

Design/methodology/approach
Upon the completion of a backward curriculum design process, the authors utilized learning analytics to improve advising, student reflection, remediation and curriculum evaluation. The learning management system incorporated the learning analytics tool to assist the learning analytics process. The course faculty, student advisors and students utilized the learning analytics throughout the academic year.

Findings
Unlike relying merely on student grades and other proxy indicators of learning, the learning analytics tool provided immediate and direct data to multiple stakeholders for advising, student reflection, student remediation and course curriculum evaluation. The authors believe it was a meaningful endeavor. It enabled meaningful conversations focusing on course learning objectives and provided detailed information on each student. The learning analytics tool also provided detailed information regarding which areas faculty needed to improve in the curriculum.

Originality/value
Most of the literature on learning analytics present the cases that administrators utilized learning analytics to make higher level decisions and researchers to explore the factors involved in learning. This paper provides cases to faculty regarding how learning analytics can benefit the faculty and the students.
