The effect of nutrient storage on courtship behavior and copulation frequency in the fruit fly,Drosophila melanogaster
Authors: Bougleux Gomes Hannah Ananda , DiAngelo Justin R. , Santangelo Nicholas 
Published: May 2018

AbstractNutrient storage and metabolism effects on reproductive behavior are well studied in higher vertebrates like mammals, but are less understood in simpler systems.Drosophila melanogasteris well suited to study the ramifications of diet and metabolic energy storage on reproductive behaviors as they are commonly used to explore energy mobilization pathways. We tested, for the first time, courtship of the naturally occurringadipose (adp60)mutant which over-accumulates triglycerides and glycogen on a normal diet. We also fed wild type (WT) flies either a normal diet, high fat diet or food deprived them before measuring courtship, copulations, and glycogen and triglyceride levels.Adiposemutants decreased both courtship and copulation frequency, yet showed the highest glycogen and triglyceride levels. We suggest theadp60physique and/or an altered ability to utilize mobilize energy explains these effects. Food deprived WT flies had the lowest glycogen and triglycerides but exhibited shortened courtship latencies with increased courtship behaviors. This may be due to a decreased lifespan of food deprived flies leading to a greater reproductive drive. However, high fat fed flies copulated more frequently and had the highest triglycerides among WT groups, yet equal glycogen levels to the normal fed WT group. Thus, a high fat diet either increases male attractivity or male courtship persistence. Taken together, available diet and nutrient storage affects male fly reproductive behavior in a unique manner, which may be explained by their natural history, and provides a paradigm for understanding energetics based on reproductive potential.

AbstractWe used inhibitory DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) to reversibly disrupt dorsolateral prefrontal cortex (dlPFC) function in male macaque monkeys. Monkeys were tested on a spatial delayed response task to assess working memory function after intramuscular injection of either clozapine-N-oxide (CNO) or vehicle. CNO injections given before DREADD transduction were without effect on behavior. rAAV5/hsyn-hM4Di-mCherry was injected bilaterally into the dlPFC of five male rhesus monkeys, to produce neuronal expression of the inhibitory (Gi-coupled) DREADD receptor. We quantified the percentage of DREADD- transduced cells using stereological analysis of mCherry-immunolabeled cells. We found a greater number of immunolabeled neurons in monkeys that displayed CNO-induced behavioral impairment after DREADD transduction compared to monkeys that showed no behavioral effect after CNO. Even in monkeys that showed reliable effects of CNO on behavior after DREADD transduction, the number of prefrontal neurons transduced with DREADD receptor was on the order of 3% of total prefrontal neurons counted. This level of histological analysis facilitates our understanding of behavioral effects, or lack thereof, after DREADD vector injection in monkeys. It also implies that a functional silencing of a relatively small fraction of dlPFC neurons, albeit in a widely distributed area, is sufficient to disrupt spatial working memory.Significance StatementCognitive domains such as working memory and executive function are mediated by the dorsolateral prefrontal cortex (dlPFC). Impairments in these domains are common in neurodegenerative diseases as well as normal aging. The present study sought to measure deficits in a spatial delayed response task following activation of viral-vector transduced inhibitory DREADD (Designer Receptor Exclusively Activated by Designer Drug) receptors in rhesus macaques and compare this to the level of transduction in dlPFC using stereology. We found a significant relationship between the extent of DREADD transduction and the magnitude of behavioral deficit following administration of the DREADD actuator compound clozapine-N- oxide (CNO). These results demonstrate it will be critical to validate transduction to ensure DREADDs remain a powerful tool for neuronal disruption.

Published: May 2018

PurposeDissertations from the University of Novi Sad (UNS) are integrated with the research information system called the current research information system (CRIS) UNS. This paper aims to present a proposal for an extension of this system to enable the storage of student papers as prescribed by PhD study exam obligations. The proposed extension enables preservation and improves discoverability of scientific and technical works produced by students during their PhD studies.Design/methodology/approachAn analysis of examination modes in accredited PhD study programs has been conducted. It was noted that students in examination modes verify the obtained results in the form of scientific and technical work. The main idea of this paper is to enable the preservation of those student results and to implement electronic services for retrieving those results by current and future PhD students to empower the development of science.FindingsThe proposal includes an extension of the CRIS UNS to store and publish student papers as prescribed as a PhD study exam obligation; an extension of the CERIF data model to enable storing of student papers; cataloguing student papers in the MARC 21 format; and a way to represent student papers in the Dublin Core format.Practical implicationsThis paper can be a starting point for initiatives for the creation of institutional, regional, national and international Web portals for searching and browsing papers by PhD students.Social implicationsThis system offers the improvement of cooperation between PhD students from different institutions and countries.Originality/valueThe paper presents an extension of institutional, national and international current research information system (CRIS) systems which will enable the preservation and improve discoverability of student papers produced during PhD studies. The proposed extension has been verified by its implementation within the CRIS UNS system, which also supports monitoring of the scientific competencies of students based on an automatic evaluation of published scientific results.
Resentment against the rich
Authors: Wu Xiaoyi , Lin Lan 
Published: May 2018

Purpose
Because of increasing wealth inequality, China has been confronted with resentment against the rich (referred to hereafter as RAR or Choufu in Chinese), which is a growing concern owing to its potential to foment social conflict. Drawing on social comparison and deonance theories, this paper aims to provide theoretical insights into RAR within the Chinese context and to develop an RAR scale. Following spillover theory, the attitudinal and behavioral outcomes of RAR in organizational settings will be explored.

Design/methodology/approach
This research consists of two studies. Study 1 conceptualizes RAR and develops an RAR scale by using three separate samples. Exploratory and confirmatory factor analyses are conducted to establish scale reliability and validity. Study 2 uses hierarchical linear regression analysis to test whether employees’ RAR attitude spills over from the societal to the organizational setting.

Findings
Results suggest that RAR can be conceptualized as two distinct but related dimensions – emotional RAR and moral RAR. These two forms spill over to the workplace, influencing employees’ work attitudes and behaviors. Emotional RAR relates negatively to life satisfaction and prosocial organizational behaviors and positively to unethical organizational behaviors. Moral RAR relates negatively to pay satisfaction and positively to prosocial behaviors.

Practical implications
This research suggests that RAR has spillover effects from societal to organizational settings and demonstrates that a more robust understanding of employees’ workplace experience requires acknowledging social experiences, such as conflicts beyond the workplace.

Originality/value
This research contributes to the conflict management literature by exploring RAR as a negative attitude that serves to potentially ignite social conflict. It not only develops a theory-grounded, conceptual RAR model and a reliable RAR scale but also for the first time explores RAR attitudinal and behavioral outcomes beyond the social domain. This study serves as a meaningful touchstone for future research to incorporate social attitudes into organizational behavior research.
Using social media for innovation – market segmentation of family firms
Authors: Raman Ramakrishnan , Menon Preetha 
Published: May 2018

PurposeThe purpose of this study is to understand the strategy adopted by family firms in using social media for their business. Based on the social media usage, this paper attempts to segment family firms. To do so, a reactive – proactive – innovative (RPI) scale was developed for the study. Then, the family firms were categorised as reactive, proactive or innovative social media users. Further, based on the scale developed, clusters were created. Family firms were placed into different clusters based on the strategy that they had for using social media platforms for their business.Design/methodology/approachA pilot sample of 50 family firms and a main study of 256 Indian family firm entrepreneurs were surveyed through self-administered questionnaires. Factor analysis reduced the 12 scale-based questions to three distinct factors. Confirmatory factor analysis was then conducted on the main sample to confirm the constructs identified using exploratory factor analysis. Cluster analysis was used to build clusters of entrepreneurs who use social media as part of their digital marketing strategy.FindingsFindings reveal that the Indian family firm market is largely divided into four main segments. These segments represent distinct behaviours with respect to the use of social media. The four segments of family firm entrepreneurs were named as high rollers, ignorant inhabitants, trend-setters, combative crowd based on their social media usage behaviour. These clusters give deep insights into the strategic usage of social media by family firms.Research limitations/implicationsThe limitation of this study is that entrepreneurs from all Indian states were not considered in the sample because of cost implications. This research study has only created the segmentation of the family firms as reactive, proactive or innovative social media users and also has created the clusters as high rollers, ignorant inhabitants, trend-setters and combative crowd. Also, the reasons for their behaviour and root cause for the strategic usage have not been studied.Practical implicationsThis study reflects on current practices of family firms with respect to usage of social media and groups them into large identifiable clusters. Equipped with the findings from this study, the RPI scale developed for the study and the clusters created, entrepreneurs can now move towards better use of social media for innovation.Originality/valueAlthough past studies have advocated the use of social media to spur innovation in firms, this study segments the current market based on their practices. It allows readers to gauge the proportion of family firms using social media for innovation and paves the way for a change in behaviour amongst these firms.
Decision-making and operations in disasters: challenges and opportunities
Authors: Rodríguez-Espíndola Oscar , Albores Pavel , Brewster Christopher 
Published: May 2018

Purpose
Decision-making structures are commonly associated with the logistics challenges experienced during disaster operations. However, the alignment between the operational level and the decision-making structure is commonly overlooked. The purpose of this paper is to provide an analysis of the fit of both levels and its impact on performance.

Design/methodology/approach
The research is developed around a case study in Mexico. Through a review of the disaster management policy in the country, interviews and secondary data, the paper provides an analysis of the current decision-making structure, the logistics activities undertaken by authorities and the impact of the alignment between both components on logistics performance.

Findings
The analysis suggests that several of the challenges commonly associated with centralisation are actually rooted on its alignment with the operational level. The logistics performance is negatively affected by faulty assumptions, poorly planned procedures, inconsistent decision-making and poorly designed structures. The case showed the need to align the operational level with a centralised perspective to increase responsiveness, flexibility and the interaction between different organisations.

Originality/value
This paper identifies the impact of the misalignment between the decision-making structure and the operational level on logistics performance, an area currently understudied. It moves from the current argument about the appropriate decision-making structure for disaster management to the identification of components to implement an efficient and effective disaster management system. Additionally, this paper provides recommendations for best practices in humanitarian logistics, which are applicable to Mexico and other countries using a centralised decision-making approach.
Vicarious interaction
Authors: Lee Nicole , Seltzer Trent 
Published: May 2018

Purpose
The purpose of this paper is to explore how online interaction with an organization impacts not only those users participating in the exchange, but also those that witness the interaction and are influenced as suggested by social cognitive theory.

Design/methodology/approach
This study utilized a mixed methodological approach. First, 20 interviews with social media users were conducted to explore their perceptions of observed two-way communication between organizations and other users within social media spaces. An experiment then compared the effects of interacting with an organization via social media vs simply observing organizations interacting with other users.

Findings
The findings from both studies support the assertion that publics do not have to actively participate in two-way communication with an organization for an observed exchange to have an impact. When an organization has a conversation with one follower, others see that interaction and are affected by it.

Practical implications
This study has implications for the practice of online communication by organizations. Practitioners must consider how interactions impact those publics who are observing rather than only the few who are engaging. In the social media realm, priority should be given to followers posting legitimate questions or concerns. Responding to positive comments can also improve perceptions of the organization but is seen as going above and beyond.

Originality/value
This paper introduces the concept of vicarious interaction – a phenomenon warranting further investigation by strategic communication scholars. Distinguishing between the effects of “vicarious interaction” and direct interaction could have significant consequences for the study of relational or symmetrical approaches to social media.

Published: May 2018

Purpose
Fashion subscription service is a newly emerged retailing model that provides an innovative way of shopping to meet consumers’ fashion needs. From the perspective of innovation adoption, the purpose of this paper is to provide an insight of consumers’ perceptions as well as adoption intention of this innovative retailing format.

Design/methodology/approach
This research is qualitative in nature, utilizing focus group study approach. In this paper, content analysis was applied to analyze the data.

Findings
While possessing varying degrees of knowledge about fashion subscription retailing, the participants shared the following perceptions of relative advantages, including convenience, personalization, consumer excitement, opportunities to try new styles, and opportunity to better manage their apparel budget. Concerns mainly focused on missing social shopping experiences and the hassle in the cancellation process. The overall adoption intention was high.

Research limitations/implications
Due to the nature of this research, the sample size was limited and results may not be generalized. This research paid less attention to individual differences, in terms of demographic and psychographic characteristics.

Practical implications
Future marketing could focus more on educating consumers about the attributes of the services they provide. Retailers can strategically leverage the positively perceived advantages in their marketing communications to enhance consumers’ adoption intention of their services.

Originality/value
The paper fills a gap in the literature on consumer behavior toward fashion subscription retailing and sheds light for companies in their endeavors to excel in this new retailing venue.
Managing commercial actors in strategic networks in emergency preparedness
Authors: Kaneberg Elvira 
Published: May 2018

PurposeThe purpose of this paper is to analyse the management of commercial actors in strategic networks of emergency preparedness management (EPM) in developed countries and how these strategies connect to the emergency response efficiency. This study uses collaboration, strategy, and efficiency to evaluate the private governance of the food, healthcare, and transportation sectors and follows an analysis of these sectors’ management that finds an ambivalent impact on the efficiency of the worldwide supply chain network (SCN) system. This study discusses many strategic networks and nets of commercial standards with different management structures and emphasizes illustrating the EPM context, thereby offering directions for future research.Design/methodology/approachAn empirical research approach and triangulation methodology was adopted to design the selection, evaluation, and contribution of the observed data and the humanitarian and business literature. An overview of strategic networks’ role in EPM in Sweden comprises several network approaches and considers the strategic value of three SCNs for response efficiency.FindingsThe study finds that strategic networks are relevant for EPM and response efficiency and can be delimited and adapted to developing countries’ demands. However, growing interest in networks’ strategic value for EPM stresses public-private collaboration as a strategic choice to achieve response efficiency. To offer strategic planning that ties demand with supply, public-private actors must collaborate in SCNs.Originality/valueThe study contributes to the existing literature on strategic networks, for example, industrial networks, by illustrating their strategic value for developed countries’ SCNs. It also contributes to the business literature, for example, on strategic net management. The work is original because it adopts a practical perspective involving buyers and suppliers in planning, the delimitation of their capability in nets, and the strategic value of SCN collaboration.
Analysing and classifying knowledge management publications – a proposed classification scheme
Authors: Fteimi Nora , Lehner Franz 
Published: May 2018

Purpose
The growing number of publications on knowledge management (KM) has addressed heterogeneous topics that lack integration and classification. This article closes the classification gap by presenting a classification scheme, providing an integrated overview of KM publications.

Design/methodology/approach
The development of the classification scheme follows a multistep approach. By applying a taxonomy development method, the results of a previous content analysis of 4,290 publications were processed to integrate 3,780 keywords into a classification scheme.

Findings
The classification scheme consists of 13 main categories and subcategories with six levels of detail. The scheme covers not only KM-specific keywords but also keywords from related disciplines, indicating a strong interdependence with related research domains.

Research limitations/implications
The scheme provides a starting point for ongoing collaboration within the KM community with the aim of improving the classification results and refining the scheme to manifest the core identity.

Practical implications
The scheme is helpful in understanding whether KM implementation activities in organisations are aligned with overall research activities and topics covered by publications.

Originality/value
Developing a scheme based on a prior content analysis turns out to be a unique and innovative approach that has never before been done in the KM domain.
