Authors: Martinez-Saito Mario , Konovalov Rodion , Piradov Michael A. , Shestakova Anna , Gutkin Boris , Klucharev Vasily 
Published: November 2018

AbstractCompetition for resources is a fundamental characteristic of evolution. Auctions have been widely used to model competition of individuals for resources, and bidding behavior plays a major role in social competition. Yet how humans learn to bid efficiently remains an open question. We used model-based neuroimaging to investigate the neural mechanisms of bidding behavior under different types of competition. Twenty-seven subjects (nine male) played a prototypical bidding game: a double action, with three “market” types, which differed in the number of competitors. We compared different computational learning models of bidding: directional learning models (DL), where the model bid is “nudged” depending on whether it was accepted or rejected, along with standard reinforcement learning models (RL). We found that DL fit the behavior best and resulted in higher payoffs. We found the binary learning signal associated with DL to be represented by neural activity in the striatum distinctly posterior to a weaker reward prediction error signal. We posited that DL is an efficient heuristic for valuation when the action (bid) space is continuous. Indeed, we found that the posterior parietal cortex represents the continuous action-space of the task, and the frontopolar prefrontal cortex distinguishes among conditions of social competition. Based on our findings we proposed a conceptual model that accounts for a sequence of processes that are required to perform successful and flexible bidding under different types of competition.

AbstractAbnormal accumulation of amyloid β oligomers (AβO) is a hallmark of Alzheimer’s disease (AD), which leads to learning and memory deficits. Hippocampal theta oscillations that are critical in spatial navigation, learning and memory are impaired in AD. Since GABAergic interneurons, such as somatostatin-positive (SST+) and parvalbumin-positive (PV+) interneurons, are believed to play key roles in the hippocampal oscillogenesis, we asked whether AβO selectively impairs these SST+ and PV+ interneurons. To selectively manipulate SST+ or PV+ interneuron activity in mice with AβO pathologyin vivo, we co-injected AβO and adeno-associated virus (AAV) for expressing floxed channelrhodopsin-2 (ChR2) into the hippocampus of SST-Cre or PV-Cre mice. Local field potential (LFP) recordingsin vivoin these AβO–injected mice showed a reduction in the peak power of theta oscillations and desynchronization of spikes from CA1 pyramidal neurons relative to theta oscillations compared to those in control mice. Optogenetic-activation of SST+ but not PV+ interneurons in AβO–injected mice fully restored the peak power of theta oscillations and resynchronized the theta spike phases to a level observed in control mice.In vitrowhole-cell voltage-clamp recordings in CA1 pyramidal neurons in hippocampal slices treated with AβO revealed that short-term plasticity of SST+ interneuron inhibitory inputs to CA1 pyramidal neurons at theta frequency were selectively disrupted while that of PV+ interneuron inputs were unaffected. Together, our results suggest that dysfunction in inputs from SST+ interneurons to CA1 pyramidal neurons may underlie the impairment of theta oscillations observed in AβO-injected micein vivo.Our findings identify SST+ interneurons as a target for restoring theta-frequency oscillations in early AD.

Published: November 2018

AbstractIndividuals vary in their behavioral and physiological responses to environmental changes. These behavioral responses are often described as ‘coping styles’ along a proactive-reactive continuum. Studies in laboratory populations often, but not always, find that behavioral responses and physiological responses to stressors covary, where more proactive (more aggressive and active) individuals have a lower physiological stress response, specifically as measured by hypothalamic-pituitary-adrenal (HPA) axis activity. These studies support the possibility of hormonal pleiotropy underlying the presentation of behaviors that make up the proactive-reactive phenotype. However, recent research in wild populations is equivocal, with some studies reporting the same pattern as found in many controlled laboratory studies, whereas others do not. We tested the hypothesis that physiological and behavioral stress responses are correlated in wild adult North American red squirrels (Tamiasciurus hudsonicus). We used fecal cortisol metabolites (FCMs) as a non-invasive, integrated estimate of circulating glucocorticoids for our measurement of HPA axis activity. We found that FCM concentrations were not correlated with three measures of behavioral coping styles (activity, aggression, and docility) among individuals. This does not support the hypothesis that hormonal pleiotropy underlies a proactive-reactive continuum of coping styles. Instead, our results support the “two-tier” hypothesis that behavioral and physiological stress responses are independent and uncorrelated traits among individuals in wild populations that experience naturally varying environments rather than controlled environments. If also found in other studies, this may alter our predictions about the evolutionary consequences of behavioral and endocrine coping styles in free-living animals.Significance StatementIndividuals vary in how they respond to stressors through behavior and physiology, but we find the two responses are independent in wild animals. Many laboratory studies find links between the behavioral and physiological stress responses, however studies conducted with wild populations are less conclusive. In wild North American red squirrels, independence between the physiological response and behavioral response may allow adaptive responses to a changing environment without pleiotropic constraint.
Comparing psychopathology rates across autism spectrum disorders and intellectual disabilities
Authors: Matthews Martyn , Bell Elliot , Mirfin-Veitch Brigit 
Published: November 2018

PurposeThe purpose of this paper is to compare the rates and patterns of comorbid anxiety, depression and ADHD across people with: autism spectrum disorder (ASD) plus intellectual disability (ID), ASD/no ID (AS/HFA) and ID only.Design/methodology/approachData were obtained using structured file review and two psychometric screening instruments. File reviews used a modified version of the Case Review Protocol from the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities. Screening employed the Reiss Screen for Maladaptive Behaviour and the ASD-Comorbidity-Adults scale.FindingsLevels of anxiety, depression and ADHD were high for all three groups, and greater than in general population studies. Between groups, the AS/HFA sample had significantly higher anxiety, while the ASD/ID group had significantly greater ADHD. Groups did not differ on measures of depression or total psychopathology. Levels of ADHD, but not anxiety or depression, increased with severity of ID and ASD symptoms.Research limitations/implicationsMore research is needed on the relationship between ASD and both anxiety and ADHD, particularly the identification of these comorbid conditions and their treatment.Practical implicationsRigorous screening for comorbid mental health conditions is required to achieve the best outcomes for adults with ASD.Originality/valueThe study used a broader community-based sample than previous comorbidity research. Including adults with ID but without ASD enabled a comparison of types and rates of disorder across three distinct but related groups with neurodevelopmental disorders.
On the organic combination of public ownership and market economy
Authors: Zhang Yu 
Published: November 2018

Purpose
Since the implementation of reform and opening up, China has made remarkable achievement in terms of economic reform and development. China’s path, as well as its experience, has simultaneously gained worldwide concerns. Developing the market economy against the backdrop of socialism brings conclusions from China’s achievement, deepens knowledge of China’s pathway and builds a socialist political economy with Chinese characteristics. That is the way to realise a basic socialist system, especially with regards to the organic integration of public ownership and market economy. This combination determines the future of socialism with Chinese characteristics and the success or failure of economic restructuring. Therefore, it requires consideration and in-depth study. The paper aims to discuss these issues.

Design/methodology/approach
The goal of economic restructuring is to establish and develop the socialist market economy. Its main content can be summarised in two parts. The first is the relationship between plan and market or government and market. The second is compatibility or combination of public ownership and market economy. The former is one of the superficial problems, relevant to resource allocation method or economic operation mechanism. The latter stems from deep-rooted problems, represented by ownership or the underlying economic system. These two work together to form the organic integrity of socialist market economy where both similarities and contrasts coexist.

Findings
The shared ideal of socialism with Chinese characteristics and the lofty goals of communism will then become empty words. In this sense we can say that, whether we can realise the unity and opposition between public ownership and market economy and better integrate advantages of socialist system with strengths of market economy, will to a large extent determine the future and destiny of the socialist market economy.

Originality/value
As previously mentioned, the relationship between plan and market or government and market are part of resource allocation methods or economic operation mechanism. Compatibility and combination, however, with public ownership and market economy are part of an ownership or basic economic system. Science reveals the nature and developmental law of the socialist market economy. An in-depth study must be conducted on the relationship between public ownership and market economy.
Yemen and education
Authors: Webb Carol 
Published: November 2018

PurposeThe purpose of this paper is to draw from up-to-date reports that outline the current situation for Yemen in terms of education and the socio-political context, and to address this context with theory from the complexity science domain in order to propose practical recommendations.Design/methodology/approachThe paper outlines highlights from the current situation in Yemen, namely, the challenges presented by conflict, and international engagement in conflict, and offers an appraisal of key factors pertaining to education and progress made in this arena in recent years. A focus is made on tribal groups as a starting point for bottom-up emergent engagement, and complexity science is suggested as a theoretical domain to draw from to conceptualise how to enact this.FindingsA discussion of how complexity science could be meaningfully applied to the case of education in Yemen is presented, along with seven recommendations for the focus of future international aid interventions in Yemen.Originality/valueAt this time, there are few, if no, other works that have been found that have considered the case of education in Yemen in this way from the perspective of a bottom-up emergent engagement with tribes as a way of leveraging the values-based system of tribal customary law in order to address sustainability development goals, literacy, integration in digital society and education as a means of approaching these issues.
Making sense of consumers’ tweets
Authors: Pantano Eleonora , Giglio Simona , Dennis Charles 
Published: November 2018

Purpose
Consumers online interactions, posts, rating and ranking, reviews of products/attractions/restaurants and so on lead to a massive amount of data that marketers might access to improve the decision-making process, by impacting the competitive and marketing intelligence. The purpose of this paper is to develop understanding of consumers online-generated contents in terms of positive or negative comments to increase marketing intelligence.

Design/methodology/approach
The research focuses on the collection of 9,652 tweets referring to three fast fashion retailers of different sizes operating in the UK market, which have been shared among consumers and between consumer and firm, and subsequently evaluated through a sentiment analysis based on machine learning.

Findings
Findings provide the comparison and contrast of consumers’ response toward the different retailers, while providing useful guidelines to systematically making sense of consumers’ tweets and enhancing marketing intelligence.

Practical implications
The research provides an effective and systemic approach to accessing the rich data set on consumers’ experiences based the massive number of contents that consumers generate and share online and investigating this massive amount of data to achieve insights able to impact on retailers’ marketing intelligence.

Originality/value
To best of the authors’ knowledge, while other authors tried to identify the effect of positive or negative online comments/posts/reviews, the present study is the first one to show how to systematically detect the positive or negative sentiments of shared tweets for improving the marketing intelligence of fast fashion retailers.
Open access institutional repositories in universities in East Africa
Authors: Kakai Miriam , Musoke Maria G.N. , Okello-Obura Constant 
Published: November 2018

PurposeGiven that repositories were proposed as one of the routes to open access (OA), this study sought to establish the achievements universities in East Africa had attained in initiating institutional repositories (IRs), the challenges in providing OA and strategies for the way forward.Design/methodology/approachData were collected through literature searches, using the internet, journal databases and university websites in Kenya, Tanzania and Uganda for information about OA and IRs in East Africa. Some of the findings were based on the author’s PhD “The management and accessibility of OA IRs in selected universities in East Africa”, which used face-to-face interviews with six librarians and self-administered questionnaires responded to by 183 researchers at Kenyatta University, Muhimbili University of Health and Allied Sciences and Makerere University.FindingsUniversities in East Africa were still in the intermediate stages of embracing OA, and only 40 libraries out of 145 universities had implemented IRs. However, most of the repositories had less than 1,000 items, with this challenge attributed to the absence of institutional and government/funder mandates that affected the collection/provision of OA, in addition to the lack of awareness of IRs among researchers.Originality/valueThe value in this research was establishing the extent of IR initiatives in universities in East Africa and their contribution to OA, which is regarded as more visible and accessible to scholars and government personnel who could leverage the information for further development in the region.

The unified crime theory and the social correlates of crime and violence: problems and solutions
Authors: Kavish Nicholas , Boutwell Brian 
Published: November 2018

PurposeCriminology has produced more than a century of informative research on the social correlates of criminal behavior. Recently, a growing body of theoretical and empirical work has begun to apply evolutionary principles, particularly from life history theory (LHT), to the study of crime. As this body of research continues to grow, it is important that work in this area synthesizes evolutionary principles with the decades of sociological research on the correlates of crime. The paper aims to discuss these issues.Design/methodology/approachThe current paper reviews the brief history of research applying life history concepts to criminology, providing an overview of the underlying framework, exploring examples of empirically testable and tested hypotheses that have been derived from the theory, discussing cautions and criticisms of life history research, and discussing how this area of research can be further integrated with existing theory.FindingsA growing body of research has, with relative consistency, associated indicators of a faster life history strategy with aggression and violence in humans and across the animal kingdom. Research into these associations is still vulnerable to genetic confounding and more research with genetically sensitive designs is needed. The use of hypotheses informed by evolutionary insight and tested with genetically sensitive designs provides the best option for understanding how environmental factors can have an impact on violent and criminal behavior.Originality/valueThe current paper provides an updated review of the growing application of LHT to the study of human behavior and acknowledges criticisms and areas of concern that need to be considered when forming hypotheses for research.
Development of an Industry 4.0 maturity model for the delivery process in supply chains
Authors: Asdecker Björn , Felch Vanessa 
Published: November 2018

PurposeThis paper aims to show that current Industry 4.0 maturity models primarily focus on manufacturing processes. Until now, research has been lacking with regard to outbound logistics, that is, the delivery process. This paper develops such a model.Design/methodology/approachMethodologically, this paper is grounded in design science research (DSR) and rigorously follows the model development guidelines presented by De Bruinet al.(2005). This work builds on current maturity models and original empirical research to populate and test the model.FindingsThe model appears to be applicable to describing the status quo of the digitization efforts in outbound logistics, developing a corporate vision for delivery logistics excellence and providing guidance on the development path.Research limitations/implicationsThus far, the model has been applied only for a development stakeholder. For further validation, the authors are currently working on additional case studies to demonstrate the model’s applicability.Practical implicationsThe developed model provides guidance for the digitization of an important value-adding activity in supply chain management: the delivery process.Originality/valueTo the authors’ knowledge, the proposed model is the first to explicitly consider the delivery process; therefore, it complements available approaches that focus on the manufacturing process. Moreover, the results show that the widely used Supply Chain Operations Reference model can serve as the basis for additional process maturity models.
Deepening democracy or stabilization?
Authors: Hatab Shimaa 
Published: November 2018

Purpose
Is the need for stability pre-empting the need for democratic values? How can the EU cope with two contradictory security requirements: the need to promote democratic norms and to secure geostrategic interests? This paper takes on the security-democracy dilemma in a complex way that transcends the realpolitik frame overshadowing the analysis of the EU’s policy orientation in the Southern Mediterranean while considering its normative role as a fig leaf for security interests.

Design/methodology/approach
This paper investigates the EU’s foreign policy orientation reflected in the ENP in terms of the two logics of action of consequentialism and appropriateness. Tracing changes at the policy level over time between 2011 and 2015, the paper zooms into the implementation of the “new” ENP in the aftermath of the Arab uprisings in Egypt, Libya and Tunisia to highlight additional variation across countries.

Findings
Building on a document analysis of the official declarations for the policy-making level and of ENP action plans for the implementation level, the paper argues that local political dynamics and the level of the EU’s threat perception shape the EU’s response to the partner countries.
Protective effects of diphenyleneiodonium, an NADPH oxidase inhibitor, on lipopolysaccharide‐induced acute lung injury

SummaryNADPH oxidase (NOX) plays an important role in inflammatory response by producing reactive oxygen species (ROS). The inhibition of NOX has been shown to induce anti‐inflammatory effects in a few experimental models. The aim of this study was to investigate the effects of diphenyleneiodonium (DPI), a NOX inhibitor, on lipopolysaccharide (LPS)‐induced acute lung injury (ALI) in a rat model. Sprague‐Dawley rats were intraperitoneally administered by DPI (5 mg/kg) 30 minutes after intratracheal instillation of LPS (3 mg/kg). After 6 hours, bronchoalveolar lavage fluid (BALF) and lung tissue were collected. The NOX activity in lung tissue was significantly increased in LPS‐treated rats. It was significantly attenuated by DPI. DPI‐treated rats showed significant reduction in the intracellular ROS, the number of inflammatory cells, and cytokines (TNF‐α and IL‐6) in BALF compared with LPS‐treated rats. In lung tissue, DPI‐treated rats showed significantly decreased malondialdehyde content and increased activity of glutathione peroxidase and superoxide dismutase compared with LPS‐treated rats. Lung injury score, myeloperoxidase activity, and inducible nitric oxide synthase expression were significantly decreased in DPI‐treated rats compared with LPS‐treated animals. Western blotting analysis demonstrated that DPI significantly suppressed LPS‐induced activation of NF‐κB and ERK1/2 and SAPK/JNK in MAPK pathway. Our results suggest that DPI may have protective effects on LPS‐induced ALI thorough anti‐oxidative and anti‐inflammatory effects which may be due to inactivation of the NF‐κB, ERK1/2, and SAPK/JNK pathway. These results suggest the therapeutic potential of DPI as an anti‐inflammatory agent in ALI.
