Published: October 2017

AbstractIncreased memory load is often signified by enhanced neural oscillatory power in the alpha range (8–13 Hz), taken to reflect inhibition of task-irrelevant brain regions. The corresponding neural correlates of memory decay, however, are not yet well-understood. Here, we investigated auditory sensory memory decay using a delayed matching-to-sample task with pure-tone sequences. First, in a behavioral experiment we modeled memory behavior over six different delay-phase durations. Second, in a magnetoencephalography (MEG) experiment, we assessed alpha-power modulations over three different delay-phase durations. In both experiments, the temporal expectation for the to-be-remembered sound was manipulated, so that it was either temporally expected or not. In both studies, memory performance declined over time but this decline was less strong under a more precise temporal expectation. Similarly, patterns of alpha power in and alpha-tuned connectivity between sensory cortices changed parametrically with delay duration (i.e., decrease in occipito-parietal regions, increase in temporal regions). Notably, temporal expectation counteracted alpha-power decline in heteromodal brain areas (i.e., supramarginal gyrus), in line with its memory-decay counteracting effect on performance. Correspondingly, temporal expectation also boosted alpha connectivity within attention networks known to play an active role during memory maintenance. The present data outline how patterns of alpha power orchestrate sensory memory decay, and encourage a refined perspective on alpha power and its inhibitory role across brain space and time.Significance StatementOur sensory memories of the physical world fade quickly. We show here that this decay of sensory memory can be counteracted by so-called temporal expectation, that is, knowledge of when to expect the to-be-remembered sensory event (here, brief sound patterns). We also show that distinct patterns and modulations of neural oscillations in the “alpha” (8–13 Hz) range index both, the degree of memory decay, and any benefit from temporal expectation, both of which affect memory performance. Critically, spatially distributed cortical patterns of alpha power, with opposing effects in auditory vs. visual sensory cortices and alpha-tuned connectivity changes within supramodal attention networks, reflect the allocation of neural resources as sensory memory representations fade.

SUMMARYFaithful meiotic chromosome inheritance and fertility relies on the stimulation of meiotic crossover recombination by potentially genotoxic DNA double-strand breaks (DSBs). To avoid excessive damage, feedback mechanisms down-regulate DSBs on chromosomes that have successfully initiated crossover repair. InSaccharomyces cerevisiae, this regulation requires the removal of the conserved DSB-promoting protein Hop1/HORMAD during chromosome synapsis. Here, we identify privileged end-adjacent regions (EARs) spanning roughly 100 Kb near all telomeres that escape DSB downregulation. These regions retain Hop1 and continue to break in pachynema despite normal synaptonemal complex deposition. Differential retention of Hop1 requires the disassemblase Pch2/TRIP13, which preferentially removes Hop1 from telomere-distant sequences, and is modulated by the histone deacetylase Sir2 and the nucleoporin Nup2. Importantly, the uniform size of EARs among chromosomes contributes to disproportionately high DSB and repair signals on short chromosomes in pachynema, suggesting that EARs partially underlie the curiously high recombination rate of short chromosomes.
Hemispheric lateralization of Heschl’s gyrus and amygdala subdivisions are involved in differentiating happy and sad acoustic emotion
Authors: Manno Francis A. M. , Fernández-Ruíz Juan , Barrios Fernando A. 
Published: October 2017

AbstractEmotion is known to activate different areas of the cortex; nevertheless, how activation represents the variety of emotion is unknown. We asked whether functional activation in Heschl’s gyrus and amygdala subdivisions could differentiate happy and sad acoustic stimuli. A sparse sampling fMRI paradigm assessing hemispheric laterality by subdivision was employed to investigate this question. Differences between left Heschl’s gyrus subdivisions Te1.1 and Te1.0 compared to Te1.2 were significant for sad acoustic stimuli and right Heschl’s gyrus subdivisions Te1.0 different than Te1.1 and Te1.2 for sad acoustic stimuli, with no subdivision specificity for happy greater than sad. A prominent right greater than left difference was notable for centromedial, laterobasal, and superficial amygdala subdivisions for sad, while happy was more bilaterally activated. Activation and deactivation profiles of Heschl’s gyrus and amygdala subdivisions added to the explanation of left/right asymmetry by emotion with activation profiles significant for Heschl’s gyrus and amygdala response to sad.

Published: October 2017

ABSTRACTDeciphering the potential of non-coding loci to influence gene regulation has been the subject of intense research, with important implications in understanding genetic underpinnings of human diseases. Massively parallel reporter assays (MPRAs) can measure regulatory activity of thousands of DNA-sequences and their variants in a single experiment. With increasing number of publically available MPRA datasets, one can now develop data-driven models which, given a DNA-sequence, predict its regulatory activity. Here, we performed a comprehensive meta-analysis of several MPRA datasets in a variety of cellular contexts. We first applied an ensemble of methods to predict MPRA output in each context and observed that the most predictive features are consistent across datasets. We then demonstrate that predictive models trained in one cellular context can be used to predict MPRA output in another, with loss of accuracy attributed to cell-type specific features. Finally, we show that our approach achieves top performance in the Fifth Critical Assessment of Genome Interpretation “Regulation Saturation” Challenge for predicting effects of single nucleotide variants. Overall, our analysis provides insights into how MPRA data can be leveraged to highlight functional regulatory regions throughout the genome and can guide effective design of future experiments by better prioritizing regions of interest.
What makes restaurateurs adopt healthy restaurant initiatives?
Authors: Seo Sunhee (Sunny) , Lee Hyunjeong 
Published: October 2017

Purpose
The purpose of this paper is to uncover what affected restaurateurs in their intention to participate in the healthy restaurant initiative.

Design/methodology/approach
In all, 53 restaurateurs who participated in healthy restaurant initiatives in Korea responded to a survey. Multiple regression analysis was conducted to reveal the influences of perceived innovation characteristics (PICs), attitudes, subjective norm, and perceived behavioral control (PBC) on the intention to sustain a healthy restaurant.

Findings
The results showed that PBC, attitudes toward healthy restaurants, relative advantage for restaurants, and complexity among PICs were significant influences on the intention to sustain healthy restaurant initiatives.

Research limitations/implications
This research has made the first attempt to evaluate healthy restaurant initiatives using the perspectives of restaurateurs who actually participated in healthy restaurant initiatives. Also, this study extends the research model testing behavior intention using the theory of planned behavior and the innovation adoption theory to investigate the influences on restaurateur intentions to sustain healthy restaurant initiatives.

Practical implications
The findings indicate that operators must have access to sufficient technical resources and a sense of self-efficacy, which encourage restaurateurs to maintain healthy restaurant initiatives. Enhancing positive attitudes and the relative advantages of the healthy restaurant initiatives also encouraged participation. Finally, voluntary and continuous participation and expansion of healthy restaurant initiatives require community and government support, a simple use of process to change, and a good understanding of the relative advantages of healthy restaurant initiatives.

Originality/value
This study first illustrates the factors that best explain the intention to sustain a healthy restaurant from the perspective of restaurateurs. PICs shed light on how complexity and relative advantage for customers helps predict intentions to sustain healthy restaurant initiatives.
Influence of online product presentation on consumers’ trust in organic food
Authors: Yue Liuqing , Liu Yongmei , Wei Xuhua 
Published: October 2017

Purpose
Against the background of industrialisation and modernisation of agriculture, food production issues and environmental hazards have become more and more obvious and consumers are increasingly concerned about food safety and health, which is strengthening demand for organic food. E-commerce provides a new channel for sales. Research on consumer trust in online organic food sales is the basis of network marketing. The paper aims to discuss these issues.

Design/methodology/approach
A laboratory experiment was used to empirically test the effects of media richness on consumers’ trust and the moderating effect of online review length. A 2×2 factorial design (i.e. two types of online product presentation formats (between-subject)×two levels of online review lengths (between-subject)) was used.

Findings
Media richness has a significant positive effect on consumers’ trust and that this effect is moderated by online review length. Meanwhile, perceived risk conveys the interaction effect of the media richness of online product presentation and online review length to trust.

Practical implications
E-commerce websites should aim to promote organic food by using a variety of online product presentation formats and by presenting high quality online reviews in order to reduce consumers’ perceived risk and improve their degree of trust when buying online.

Originality/value
This paper provides a new insight into consumers’ attitude of buying organic food online. The results of the research could provide proposals for promoting organic food sales online.
Eating habits associated with body weight gain in female university students
Authors: Sprake Eleanor , Lavin Jacquie , Grabowski Peter , Russell Jean , Featherstone Megan , Barker Margo 
Published: October 2017

Purpose
The purpose of this paper is to explore factors associated with body weight gain among British university students who were members of a slimming club.

Design/methodology/approach
Student members of a national commercial slimming programme completed an online survey about cooking ability, weight gain, eating habits and physical activity levels. Non-parametric statistical tests and regression analysis were employed to examine factors associated with weight gain.

Findings
The data set comprised 272 current students. The majority of students (67 per cent) reported weight gain between 3.2 and 12.7 kg during studying in university: 20.4 per cent reported to have gained >12.7 kg. Students commonly attributed their weight gain to academic stress and nearly all identified with needing support to learn to cook on a budget. Students reporting greatest weight gain had most frequent consumption of ready meals & convenience foods, take-away & fast foods and least frequent consumption of fruits & vegetables. Weight-stable students reported lowest consumption of alcohol and were most able to cook complex meals. Students who reported greatest weight gain reported lower physical activity levels. There were inter-correlations between cooking ability and lifestyle factors. In a multivariate model, low physical activity and frequent consumption of ready meals and convenience food independently predicted weight gain.
Weight gain was inversely associated with diet quality, cooking ability and physical activity with reliance on ready meals & convenience food and low physical activity particularly important. Prospective studies are needed to confirm these cross-sectional associations and to explore how the university setting may contribute to the effect.

Originality/value
The study adds additional perspective to understanding student weight gain at university in that it focuses on a body weight-conscious sub-group of the student population, as opposed to the general population of students.
Bankarization in the first European cities with an equal number of Muslim and Christian inhabitants
Authors: Pérez-Castro Miguel Ángel , Montero-Alonso Miguel Ángel , Abderrahman-Azaar Akram 
Published: October 2017

Purpose
This paper aims to analyze the situation of the financial system in the Spanish-governed cities of Melilla and Ceuta, Christian and Muslim cities located on the north coast of Africa, and compared it with the mean bankarization level in the rest of Spain in 2000-2015.

Design/methodology/approach
Although different calculation methods have been proposed, most authors agree that the bankarization level of a country or a territory reflects the development of the society as a whole and has a positive correlation with economic growth. The indicators of financial depth proposed by these researchers are not only the ratio between variables such as loans, deposits, etc., but also the ratios of these variables to the population and the gross domestic product (GDP) of the country or territory.

Findings
The results obtained revealed that there are differences between these two North African Spanish cities. Furthermore, the financing gap between the mean bankarization levels of these cities and those of mainland Spain was found to be even larger than most of the other economic indicators (GDP per capita and the unemployment rate).

Practical implications
The authors are convinced that the manuscript is a contribution of great interest for serving pilot experience in cities wishing to offer a development of traditional banking and Islamic banking. The paper should be of interest to readers in the areas of finance systems and commercial banks where two different cultures coexist.

Originality/value
This is the first research study on the financial framework of European cities whose populations have an approximately equal percentage of Christians and Muslims. The data reflected the existence of savings and loan methods parallel to conventional banking. The conclusion was that in the near future, it would be advisable for European banks to take into account the cultural customs and religious practices of potential Muslim clients.

Origins of sports car marketing: early 20th Century British cycle-cars
Authors: Jones D.G. Brian , Richardson Alan J. 
Published: October 2017

PurposeThe aim of this study is to explore the attempts by early twentieth century cyclecar manufacturers in the UK and USA to segment the personal transportation market and to position early cyclecars through the development of unique product attributes and advertising. More specifically, the authors speculate about early twentieth century British cyclecar marketing strategies that implicitly recognized a sports car segment and positioned cyclecar brands to meet the needs of that segment.Design/methodology/approachThe primary source material for this research is a sample of 205 print ads and articles from the early twentieth century (1912-1921) specialty magazines devoted to cyclecars in the UK and USA. We combine the content analysis of the sample of ads with a critical reading and interpretation of a sub-sample of those same ads.FindingsBetween 1910 and 1921, a new form of personal transportation was developed that combined the technology of motorcycles with the utility of automobiles. Known as “cyclecars”, these vehicles were typically constructed from off-the-shelf motorcycle parts and assembled in small batches by a myriad of manufacturers. Current scholarship suggests that the cyclecar craze of the 1910s ended with the introduction of low cost “real” automobiles such as the Ford Model T, Austin 7 and Morris Oxford. We use the content analysis of cyclecar advertisements to construct a brand-positioning map of this emerging segment of the transportation market. We argue that while the core cyclecar positioning was in direct competition with small economically positioned cars such as the Ford Model T, a significant part of the market, primarily centered in the UK, could be considered as for sports cars. That segment of the cyclecar market, along with the development of cyclecars into urban delivery vehicles, continued over time and has re-emerged today in a range of three-wheeled sports cars, including the updating and continuation of the British Morgan 3 Wheeler model which was launched during the heyday of cyclecars.Research limitations/implicationsThe authors can only speculate about the impact of the Ford Model T in this study. Further research on that issue is needed.Originality/valueThis is the first historical study of cyclecar marketing. Most of what little has been published about cyclecars focuses on their design and technology.
The case for employee resource groups
Authors: Welbourne Theresa M. , Rolf Skylar , Schlachter Steven 
Published: October 2017

PurposeThe purpose of this paper is to demonstrate that employee resource groups (ERGs) are a valuable addition to organizations and should be an important focus of research, particularly given the diversity and inclusion challenges faced by many businesses and communities today.Design/methodology/approachThe authors review the ERG literature, develop a theoretical framework using social identity theory (SIT) and suggest research directions.FindingsERGs represent a fairly unexplored area of research. Using SIT, a series of propositions is presented for research into ERG effects on individual, group and organizational outcomes.Research limitations/implicationsERGs have impact beyond the topics explored using SIT. As ERGs become more prominent, there is ample room to conduct empirical research to learn more about the underlying process by which ERGs are affecting identity and employee integration (or lack of) into groups and organizations.Originality/valueDespite their prevalence in the business world, there has been a scarce amount of theorizing and research focused on ERGs. To help facilitate the development of this work, the authors introduce a theoretical framework using SIT, as well as propositions that can serve to spur additional research on a critical topic for today’s businesses.
Passion or people? Social capital and career sustainability in arts management
Authors: Richardson Julia , Jogulu Uma , Rentschler Ruth 
Published: October 2017

PurposeThe purpose of this paper is to examine the role of social capital for career success and sustainability among arts managers and the implication for human resource practice.Design/methodology/approachThis paper is a qualitative study comprising interviews with 73 arts managers in Australia.FindingsWhile answering an occupational calling and having a sense of passion for the arts is a key driver to embark upon a career in arts management, it is social capital that is essential for both objective and subjective career success and thus for career sustainability. The authors also identify the value of education, global experience and well-honed soft skills for building social capital.Research limitations/implicationsThe study is located in Australia – arts management in other national contexts and industries may be different.Practical implicationsThis paper identifies the need for arts managers to develop heterogeneous social capital to support both career success and sustainability. It also indicates that whereas passion for the arts may be an important driver, other skills and competencies are required. Both of these themes need to be incorporated into human resource practice in the arts industry.Social implicationsThis paper demonstrates the growing need to acknowledge the impact of relational social capital in the arts in an increasingly volatile work environment.Originality/valueThis paper fills the gap in our understanding of careers that bridge both the arts and management as professional domains of activity and extends understanding on the role of social capital in management careers more generally.
