The functional convergence and heterogeneity of social, episodic, and self-referential thought in the default mode network
Authors: Wen Tanya , Mitchell Daniel J , Duncan John 
Published: September 2019

AbstractThe default mode network (DMN) is engaged in a variety of cognitive settings, including social, semantic, temporal, spatial, and self-related tasks. Andrews-Hanna et al. (2010, 2012) proposed that the DMN consists of three distinct functional-anatomical subsystems – a dorsal medial prefrontal cortex (dMPFC) subsystem that supports social processing and introspection about mental states; a medial temporal lobe (MTL) subsystem that contributes to memory retrieval and construction of mental scenes; and a set of midline core hubs that are involved in processing self-referential information. We examined activity in the DMN subsystems during six different tasks: (1) theory of mind and (2) moral dilemmas (for social cognition), (3) autobiographical memory and (4) spatial navigation (for memory-based construction/simulation), (5) self/other adjective judgement (for self-related cognition), and finally, (6) a rest condition compared to a working memory task. At a broad level, we observed similar whole-brain activity maps for the six contrasts, and some response to every contrast in each of the three subsystems. In more detail, both univariate analysis and multivariate activity patterns showed partial functional separation, much of it in close accord with the proposals of separate dMPFC and MTL subsystems, though with less support for common activity across anterior and posterior regions of a midline core. Integrating social, spatial, self-related, and other aspects of a cognitive situation or episode, multiple components of the DMN may work closely together to provide the broad context for current mental activity.Significance StatementActivity in the default mode network (DMN) can been found across a wide range of high-level tasks that involve social, semantic, episodic, or self-referential cognition. Given this diversity, an important proposal is that the DMN can be parcellated into subsystems with different cognitive functions. The current experiment employed a wide range of experimental tasks to directly test for functional convergence and heterogeneity between DMN regions. The results support both partial differentiation and integration; working together, distributed DMN regions may assemble the multiple contextual components of a cognitive situation or episode.

Published: September 2019

AbstractMutations in coiled-coil-helix-coiled-coil-helix domain containing 10 (CHCHD10) are a genetic cause of amyotrophic lateral sclerosis and/or frontotemporal dementia (ALS-FTD). To elucidate how mutations in CHCHD10 induce disease, we generated a Drosophila melanogaster model of CHCHD10-mediated ALS-FTD. Expression of CHCHD10S59L in Drosophila caused gain-of-function toxicity in eyes, motor neurons, and muscles, in addition to mitochondrial defects in flies and HeLa cells. TDP-43 and PINK1 formed two axes, driving the mutant-dependent phenotypes. CHCHD10S59L expression increased TDP-43 insolubility and mitochondrial translocation. Blocking mitochondrial translocation with a peptide inhibitor reduced CHCHD10S59L-mediated toxicity. PINK1 knockdown rescued CHCHD10S59L-mediated phenotypes in Drosophila and HeLa cells. The two PINK1 substrates mitofusin and mitofilin were genetic modifiers of this phenotype. Mitofusin agonists reversed the CHCHD10S59L-induced phenotypes in Drosophila and HeLa cells and increased ATP production in Drosophila expressing C9orf72 with expanded GGGGCC repeats. Two peptides inhibitors of PINK1 mitigated the mitochondrial defects introduced by CHCHD10S59L expression. These findings indicate that TDP-43 mitochondrial translocation and chronic activation of PINK1-mediated pathways by CHCHD10S59L generate dominant toxicity. Therefore, inhibiting PINK1 activity may provide a therapeutic strategy for CHCHD10-associated disease.One Sentence SummaryInhibition of TDP-43 mitochondrial translocation or PINK1 kinase activity mitigates CHCHD10S59L-mediated mitochondrial toxicity.
In vitro and in vivo roles of glucocorticoid and vitamin D receptors in the control of cardiomyocyte proliferative potential
Authors: Cutie Stephen , Lunn Dominic , Huang Guo N. 
Published: September 2019

ABSTRACTCardiomyocyte (CM) proliferative potential varies considerably across species. While lower vertebrates and neonatal mammals retain robust capacities for CM proliferation, adult mammalian CMs lose proliferative potential due to cell-cycle withdrawal and polyploidization, failing to mount a proliferative response to regenerate lost CMs after cardiac injury. The decline of murine CM proliferative potential occurs in the neonatal period when the endocrine system undergoes drastic changes for adaptation to extrauterine life. We recently demonstrated that thyroid hormone (TH) signaling functions as a primary factor driving CM proliferative potential loss in vertebrates. Whether other hormonal pathways govern this process remains largely unexplored. Here we showed that agonists of glucocorticoid receptor (GR) and vitamin D receptor (VDR) suppressed neonatal CM proliferation in vitro. We next examined CM nucleation and proliferation in mutant mice lacking GR or VDR specifically in CMs, but we observed no difference between mutant and control littermates. Additionally, we generated compound mutant mice that lack GR or VDR and express dominant-negative TH receptor alpha in their CMs, and similarly observed no increase in CM proliferative potential compared to dominant-negative TH receptor alpha mice alone. Thus, although GR and VDR activation in cultured CMs is sufficient to inhibit CM proliferation, they seem to be dispensable for CM cell-cycle exit and binucleation in vivo. In addition, given the recent report that VDR activation in zebrafish promotes CM proliferation and tissue regeneration, our results suggest distinct roles of VDR in zebrafish and rodent CM cell-cycle regulation.
A comparison of the relationship marketing outcomes of SMEs vs large enterprises in the Kuwait fast food industry
Authors: Heiens Richard A. , Pleshko Larry P. , Ahmed Ahmed A. 
Published: September 2019

Purpose
The purpose of this paper is to investigate the effects of retail chain size on a variety of relationship marketing performance measures in the Kuwait fast food industry. These include customer satisfaction, customer retention, penetration rate, preference ranking and share of customer.

Design/methodology/approach
A total of 49 fast food chains, operating a total of 508 restaurants, were included in the study. Interviews with the home office marketing managers of each chain were conducted. In addition, a quota sample of 650 consumers representative of the Kuwait population with respect to age and gender was selected for participation in the study.

Findings
Findings suggest that large enterprises (LE) exhibit superior outcomes than small- and medium-sized enterprises (SMEs) on many relationship marketing (RM) performance dimensions, including satisfaction, retention, penetration, preference and share of customer. In contrast, SMEs appear to have few advantages in achieving RM outcomes over LEs. Larger firms appear to use their superior resources to take actions to develop and manage customer relationships in ways that smaller firms cannot.

Originality/value
Kuwait is an important emerging market in the Middle East, and managers need to understand the dynamics of this specific market.

Published: September 2019

PurposeIn the midst of the Greek economic and financial crisis, food and beverage firms constitute one of the most dynamic parts of the Greek economy proved resilient in conditions of economic turbulence. The purpose of this paper is to assess the competitiveness of the Greek food and beverage firms within the context of turbulent economic conditions and draw the relevant entailed agricultural policy viewpoints.Design/methodology/approachThe analysis is based on competitiveness measures such as profitability and market share utilizing a sample of 550 firms which published their annual balance sheets the 2008–2012 period. The analysis takes place with the use of a simultaneous equations tobit model.FindingsThe main results show that market share, profitability and capital intensity affect positively both on market share and profitability, while operating costs have a negative and statistically significant effect on profitability. The rate of growth affects positively and statistically significant on profitability while the index of loans does not affect on market share. As the results indicate, food and beverages industry has proven resilient in conditions of economic turbulence without direct policy measures or subsidies.Originality/valueAmong other factors, the evolution of agricultural policy is affecting decisively the competitiveness of agro-food sector (Chaddad and Jank, 2006; Banse et al., 1999). Nevertheless, food competitiveness is significantly shaped and influenced within the broad economic climate of a country, region or the whole world. Thus, the present study tries to assess the competitiveness of Greek food and beverages sector in conditions of macroeconomic turbulence and draw the relevant entailed agricultural policy viewpoints.

Authors: Koksal Mehmet Haluk 
Published: September 2019

Purpose
The purpose of this paper is to investigate the factors underlying Lebanese consumers’ food motivations and segment them based on those motivations.

Design/methodology/approach
The data in the study were collected from the main shopping districts of the Lebanese capital, Beirut, through a structured questionnaire. Respondents were intercepted by employing simple random sampling. Out of 700 people approached, 411 surveys were collected, giving a response rate of 58.7 per cent. After gathering the food choice motives under main groups by employing exploratory factor analysis, the study used two step cluster analysis.

Findings
The food choice motives were grouped under eight dimensions: ecological, sensory, convenience and availability, health, weight, mood, price and religion motives. Based on the food choice motives, the study identified four dissimilar clusters, namely, careless, conscious, hedonic and health and weight conscious. The study clearly indicated that there are significant differences among clusters in terms of the food choice motives, attitudes towards healthy eating, exercising, food quality and natural organic food and socio demographic characteristics.

Originality/value
There are numerous studies on food choice motives in the literature investigating certain countries. This study is the first study investigating the subject in one of the Middle Eastern countries, Lebanon.
Student preferences for slogans of higher-education institutions
Authors: Kovalenko Andriy 
Published: September 2019

Purpose
The slogans adopted by higher-education institutions usually target all college stakeholders without differentiation, even though these stakeholders may have quite different connections to the organization. The purpose of this paper is to understand whether there is a relationship between students’ cultural backgrounds and their preferences for slogans of higher-education institutions.

Design/methodology/approach
The study utilized a survey for data collection. In total, 295 participants answered questions about preferences for slogans appealing to purchase or product involvement, and individualistic or collectivist values.

Findings
The results suggest that participants from both collectivist and individualistic societies prefer slogans that appeal to the values pertinent to their respective cultures. Representatives of both groups preferred slogans referring to the benefits of education over slogans describing features of particular institutions.

Practical implications
Slogans with messages appealing to people from collectivist and individualistic messages cultures should be included in promotional materials and distributed among corresponding audiences. Slogans for prospective students should refer to the advantages of studying in a particular institution, while current students should be targeted with slogans that encourage dedicated studying in general.

Originality/value
The findings contribute to the understanding of factors increasing effectiveness of higher-education slogans. It is also one of the first studies of how students from India (Punjab and Kerala states) and the Philippines process promotional materials from western educational institutions.
What is said in European Works Councils stays there
Authors: Meylemans Lise , De Spiegelaere Stan 
Published: September 2019

Purpose
The purpose of this paper is to study how employee representatives in European Works Councils (EWCs) treat confidential information and how such strategies might improve the EWC functioning.

Design/methodology/approach
Building on interviews of several case studies of EWCs, this paper brings together insights from industrial relations and occupational psychology literature.

Findings
The results show that through actively challenging the management, an EWC can reduce the amount of information labelled as confidential and become freer to communicate with their rank and file. Actively challenging management, however, does not seem to impact the openness of the management to give early and complete information.

Research limitations/implications
The paper is based on several case studies, which limits the generalisability of the findings. The results, however, indicate that research is required on how challenging confidentiality can incite managements to provide earlier information.

Practical implications
The research show clearly the potential but also limitations for employee representatives in actively challenging the management over what information is confidential.

Social implications
This study studies a universally difficult topic for employee representatives: how to handle confidential information. The findings show that EWCs have little levers to force management to provide early information. For this, more structural change is needed.

Originality/value
This study is the first to focus exclusively on the issue of confidentiality in EWCs. This is a central concern for employee representatives, but research, until now, has not given much insight in which strategies work.
The dark side? Fun in the workplace and unwanted sexual attention
Authors: Tews Michael J. , Stafford Kathryn , Jolly Phillip M. 
Published: September 2019

PurposeThe purpose of this paper is to examine whether fun in the workplace inadvertently leads to greater incidences of unwanted sexual attention. Specifically, this research examined the relationship between three dimensions of fun and unwanted sexual attention – fun activities, coworker socializing and manager support for fun.Design/methodology/approachMultiple regression was used to analyze survey data from three Qualtrics business panels.FindingsFun activities were related to greater incidences of unwanted sexual attention, while manager support for fun was related to fewer instances. With respect to fun activities, mandatory attendance and holding the activities on nights and weekends were associated with further increased unwanted sexual attention. The presence of non-employees during activities was associated with fewer incidences.Research limitations/implicationsThe data on fun in the workplace and unwanted sexual attention were obtained at one point in time. Future research would be valuable that obtains data collected at multiple points in time to more fully substantiate cause-and-effect relationships.Practical implicationsEmployers may seek to foster a climate in which managers encourage employees to have fun on the job as well as one that explicitly focuses on preventing sexual harassment. Curbing unwanted sexual attention during fun activities may be facilitated by involving non-employees, refraining from holding activities at night and on weekends and keeping employee participation voluntary.Originality/valueFrom the perspective of fun in the workplace, this research has demonstrated fun activities may have unintended, adverse consequences. From the perspective of sexual harassment, this research has identified antecedents not typically be considered to be contributing factors of unwanted sexual attention.

Degendering organizational resilience – the Oak and Willow against the wind
Authors: Witmer Hope 
Published: September 2019

Purpose
The purpose of this paper is to present a degendered organizational resilience model challenging current and dominant conceptualizations of organizational resilience by exploring how gendered organizational power structures, language and practices of everyday organizational life interplay and limit inclusive constructions of organizational resilience.

Design/methodology/approach
The degendered organizational resilience model was developed using Acker’s (1990) model of gendered organizations, Martin’s (2003) gendering practices, Lorber’s (2000) degendering and other feminist research on gendered organizations. The purpose of the model is to explore power structures, practices and language within the organizational context during conditions requiring organizational resilience.

Findings
A conceptual model for analyzing the theoretical development of organizational resilience is presented. The model analyzes the following three different aspects of organizations: power structure, to identify which resilient practices receive status based on established gendered organizational hierarchies and roles; actions, to identify how resilience is enacted through practices and practicing of gender; and language, to identify how and what people speak reinforces collective practices of gendering that become embedded in the organization’s story and culture.

Practical implications
The degendered organizational resilience model offers a process for researchers, managers and organizational leaders to analyze and reveal power imbalances that hinder inclusive theoretical development and practices of organizational resilience.

Social implications
The degendered organizational resilience model can be used to reveal power structures, gendered practices and language favoring normative masculine organizational practices, which restrict the systemic implementation of inclusive democratic practices that incorporate and benefit women, men and other groups subject to organizational subordination.

Originality/value
This paper offers an original perspective on the theoretical development of organizational resilience by proposing a degendering model for analysis. A feminist perspective is used to reveal the gendered power structures, practices and language suppressing the full range of resilient qualities by restricting what is valued and who gives voice to resilient processes that lead to resilient organizations.
Transport phenomena in MHD mixed convective nanofluid flow
Authors: Patil Prabhugouda Mallanagouda , A. Shashikant , Momoniat Ebrahim 
Published: September 2019

PurposeThis study aims to investigate the unsteady magnetohydrodynamic mixed convective nanofluid flow by using Buongiorno two-phase model to achieve an appropriate mechanism to improve the efficiency of solar energy systems by mitigating the energy losses.Design/methodology/approachThe transport phenomena occurring in this physical problem are modelled using nonlinear partial differential equations and are non-dimensionalised by using non-similar transformations. The quasilinearisation technique is used to solve the resulting system with the help of a finite difference scheme.FindingsThe study reveals that the effect of the applied transverse magnetic parameter is to increase the temperature profile and to reduce the wall heat transfer rate. The Brownian diffusion and thermophoresis parameters that characterise the nanofluids contribute to the reduction in wall heat transfer rate. The presence of nanoparticles in the fluid gives rise to critical values for the thermophoresis parameter describing the behaviour of the wall heat and mass transfer rates. Wall heating and cooling are analysed by considering the percentage increase or percentage decrease in the heat and mass transfer rates in the presence of nanoparticles in the fluid.Research limitations/implicationsThe investigation on wall cooling/heating leads to the analysis of control parameters applicable to the industrial design of thermal systems for energy storage, energy harvesting and cooling applications.Practical implicationsThe analysis of the control parameters is of practical value to the solar industry.Social implicationsIn countries, such as South Africa, daily power cuts are a reality. Any research into improving the quality of energy obtained from alternate sources is a national necessity.Originality/valueFrom the literature survey in the present study, it is found that no similar work has been reported in the open literature that analyses the time-dependent mixed convection flow along the exponentially stretching surface in the presence of the effects of a magnetic field, nanoparticles and non-similar solutions.
Meshless velocity – vorticity local boundary integral equation (LBIE) method for two dimensional incompressible Navier-Stokes equations
Authors: Sellountos E.J. , Tiago Jorge , Sequeira Adelia 
Published: September 2019

PurposeThis paper aims to describe the 2D meshless local boundary integral equation (LBIE) method for solving the Navier–Stokes equations.Design/methodology/approachThe velocity–vorticity formulation is selected to eliminate the pressure gradient of the equations. The local integral representations of flow kinematics and transport kinetics are derived. The integral equations are discretized using the local RBF interpolation of velocities and vorticities, while the unknown fluxes are kept as independent variables. The resulting volume integrals are computed using the general radial transformation algorithm.FindingsThe efficiency and accuracy of the method are illustrated with several examples chosen from reference problems in computational fluid dynamics.Originality/valueThe meshless LBIE method is applied to the 2D Navier–Stokes equations. No derivatives of interpolation functions are used in the formulation, rendering the present method a robust numerical scheme for the solution of fluid flow problems.
