Digital inequalities and social media: experiences of young people in Chile
Authors: McNicol Sarah , Aillerie Karine 
Published: August 2017

Purpose
This paper aims to report the findings from a survey of secondary school students in Chile by exploring their use of social networking services for information-seeking purposes.

Design/methodology/approach
An online survey was distributed via Chile’s Ministry of Education and 12,354 responses were received.

Findings
The results indicate that young people in Chile extensively use SNSs, but there are differences in the ways in which they use these services, specifically for information purposes. When considering school-related activities, there are differences in the use of SNSs by students in different types of schools. Those in academic-focussed institutions are more likely to use SNSs for school-related information purposes and are more likely to publish most types of information on SNSs than their counterparts in vocational schools.

Research limitations/implications
The sample was self-selecting and excluded students without online access to the survey.

Practical implications
The findings indicate more needs to be done in schools serving lower socio-economic communities to support students’ use of SNSs for information-seeking, especially for academic purposes.

Social implications
The findings suggest that school-associated social capital may have a role in shaping students’ use of SNSs for information and learning purposes and, potentially, in exacerbating digital inequalities.

Originality/value
The focus on the use of social media specifically for information-seeking distinguishes this research. The findings challenge possible assumptions about the links between social media use and social class and suggest that differences may be exacerbated by school practices.
Social media sentiment analysis: lexicon versus machine learning
Authors: Dhaoui Chedia , Webster Cynthia M. , Tan Lay Peng 
Published: August 2017

Purpose
With the soaring volumes of brand-related social media conversations, digital marketers have extensive opportunities to track and analyse consumers’ feelings and opinions about brands, products or services embedded within consumer-generated content (CGC). These “Big Data” opportunities render manual approaches to sentiment analysis impractical and raise the need to develop automated tools to analyse consumer sentiment expressed in text format. This paper aims to evaluate and compare the performance of two prominent approaches to automated sentiment analysis applied to CGC on social media and explores the benefits of combining them.

Design/methodology/approach
A sample of 850 consumer comments from 83 Facebook brand pages are used to test and compare lexicon-based and machine learning approaches to sentiment analysis, as well as their combination, using the LIWC2015 lexicon and RTextTools machine learning package.

Findings
Results show the two approaches are similar in accuracy, both achieving higher accuracy when classifying positive sentiment than negative sentiment. However, they differ substantially in their classification ensembles. The combined approach demonstrates significantly improved performance in classifying positive sentiment.

Research limitations/implications
Further research is required to improve the accuracy of negative sentiment classification. The combined approach needs to be applied to other kinds of CGCs on social media such as tweets.

Practical implications
The findings inform decision-making around which sentiment analysis approaches (or a combination thereof) is best to analyse CGC on social media.

Originality/value
This study combines two sentiment analysis approaches and demonstrates significantly improved performance.
Examining the moderating role of personality traits in the relationship between brand trust and brand loyalty
Authors: Menidjel Choukri , Benhabib Abderrezzak , Bilgihan Anil 
Published: August 2017

Purpose
The purpose of this empirical study is to investigate both the relationships among brand satisfaction, trust and loyalty and the moderating effects of personality traits, namely, consumer innovativeness, variety-seeking and relationship proneness, in the context of fast-moving consumer goods.

Design/methodology/approach
Data were collected using a survey of 443 consumers. Structural equation modeling, specifically partial least squares regression, was used to test the theoretical model.

Findings
The findings indicate that brand loyalty is the most affected (both directly and indirectly) by satisfaction through the mediation of brand trust in both product categories studied. Moreover, variety-seeking behavior negatively moderates the relationship between brand trust and brand loyalty for fruit juices.

Research limitations/implications
This research was conducted in the context of fast-moving consumer goods within a limited geographical region. Future research could apply this model to different contexts and countries.

Practical implications
Companies that produce fast-moving consumer goods are advised to consider the important role of satisfaction in the generation of trust, which leads to brand loyalty.

Originality/value
This study proposes and tests a theoretical model that is more comprehensive than the models used in previous studies because it investigates the relationships among satisfaction, trust, loyalty and personality traits. It is the first attempt to examine the moderating effects of consumer innovativeness, variety-seeking and relationship proneness on the relationship between brand trust and loyalty.
Host country consumers’ brand attitudes after cross-border acquisitions
Authors: Shi Tiebing , Li Jiandong , Lim Chi Lo 
Published: August 2017

PurposeThis study aims to investigate factors impacting host country consumers’ attitudes toward acquirers’ corporate brands and target brands after cross-border acquisitions (CBAs).Design/methodology/approachSurveys were conducted with US consumers using two fictitious CBA scenarios in the automobile industry.FindingsConsumer ethnocentric tendencies (CETs) are negatively related to attitudes toward a CBA event; attitudes toward a CBA event are positively related to post-CBA attitudes toward the acquirer's corporate brand; brand-image fit is positively related to attitudes toward a CBA event, and post-CBA attitudes toward the acquirer's corporate brand and the target brand; post-CBA attitudes toward the acquirer's corporate brand and the target brand are positively related.Research limitations/implicationsThis study is limited in the sample, analysis approaches, context and factors examined. Future research could use more representative samples and both quantitative and qualitative methodologies; conduct more tests; examine real CBAs in different industries and countries; and investigate effects of other factors affecting attitudes toward the CBA event and post-CBA brand attitudes.Practical implicationsManagers should consider CETs and brand-image fit and strategically influence attitudes toward a CBA event and post-CBA brand attitudes.Originality/valueIt investigates the mediating effect of attitudes toward a CBA event on the relationship between CETs and post-CBA attitudes toward the acquirer's corporate brand and the effects of brand-image fit on attitudes toward a CBA event and post-CBA brand attitudes.
Strategic and institutional sustainability: corporate social responsibility, brand value, and Interbrand listing
Authors: Agus Harjoto Maretno , Salas Jim 
Published: August 2017

Purpose
This study aims to investigate the impact of strategic and institutional (normative) corporate social responsibility (CSR) on brand value and brand reputation, based on the strategic and legitimacy theory of CSR. It argues that because CSR strengths represent firms’ proactive approach to satisfy their stakeholders’ interests, the authors expect that this proactive approach is likely to generate an accumulated level of reservoir of goodwill that is positively related to the level of brand value. In contrast, the authors would expect that social irresponsibility (CSR concerns), as a measure of firms’ reactive position to stakeholders’ interests, adversely affects the incremental change in this reservoir of goodwill.

Design/methodology/approach
This paper measures strategic CSR using CSR strengths and normative (institutional) CSR from CSR concerns scores from the MSCI ESG (Kinder Lydenburg Domini). This paper measures the level of brand value from the Interbrand listing, and it measures the brand reputation based on changes in brand value and brand ranking from Interbrand’s 100 global brands.

Findings
This paper finds evidence to support the authors’ theory that one-, two- and three-year lagged CSR strengths positively affect the level of brand value. This study also finds empirical evidence to support the authors’ hypothesis that CSR concerns adversely affect changes in brand value and brand ranking. This study concludes that the differing impacts of CSR strengths and CSR concerns help the authors better understand the impacts of firms’ pro-action and reaction to stakeholders’ interests ion brand values and ranking.

Practical implications
The findings indicate that strategic CSR enhances brand value, while socially irresponsible activities that are against social norms, values and ethics adversely affect the companies’ legitimacy and adversely affect changes in brand reputation.

Originality/value
This research offers a new perspective to distinguish the differing impacts of CSR strengths and concerns on brand value and brand reputation.
Fewer reasons to sin: a five-factor investigation of vice stock returns
Authors: Richey Greg 
Published: August 2017

Purpose
The purpose of this paper is to investigate the return performance of a portfolio of US “vice stocks,” firms that manufacture and sell products such as alcohol, tobacco, gaming services, national defense and firearms, adult entertainment, and payday lenders.

Design/methodology/approach
Using daily return data from a portfolio of vice stocks over the period 1987-2016, the author computes the Jensen’s α (capital asset pricing model (CAPM)), Fama-French Three-Factor, Carhart Four-Factor, and Fama-French Five-Factor results for the complete portfolio, and each vice industry individually.

Findings
The results from the CAPM, Fama-French Three-Factor Model, and the Carhart Four-Factor Model show a positive and significant α for the vice portfolio throughout the sample period. However, the α’s significance disappears with the addition of the explanatory variables from the Fama-French Five-Factor Model.

Originality/value
The author provides academics and practitioners with results from a new model. As of this writing, the author is unaware of any articles published in peer-reviewed academic journals that investigate vice stocks within the framework of the Fama-French Five-Factor Model (2015). First, the existing literature does not shed light on the relationship between “profitability” and “aggressiveness” (the fourth and fifth factors of the Fama-French Model) and vice stock returns. Second, within the framework of the Fama-French Five-Factor Model, the author shows results not only from a portfolio of vice stocks, but from various vice industries as well.
Self‐disclosure, trauma and the pressures on the analyst
Authors: West Marcus 
Published: August 2017

AbstractThis paper argues that self‐disclosure is intimately related to traumatic experience and the pressures on the analyst not to re‐traumatize the patient or repeat traumatic dynamics. The paper gives a number of examples of such pressures and outlines the difficulties the analyst may experience in adopting an analytic attitude – attempting to stay as closely as possible with what the patient brings. It suggests that self‐disclosure may be used to try to disconfirm the patient's negative sense of themselves or the analyst, or to try to induce a positive sense of self or of the analyst which, whilst well‐meaning, may be missing the point and may be prolonging the patient's distress. Examples are given of staying with the co‐construction of the traumatic early relational dynamics and thus working through the traumatic complex; this attitude is compared and contrasted with some relational psychoanalytic attitudes.
Prenatal androgen receptor activation determines adult alcohol and water drinking in a sex‐specific way

Published: August 2017

AbstractAlcohol use disorders are major psychiatric disorders. Correlational studies in humans suggested organizational hormonal effects during embryonic development as a risk factor for adult alcohol dependence. Permanent changes can be induced by the activity of sex hormones, like testosterone. Here, we demonstrate a relationship between prenatal androgen receptor (AR)‐activation and adult alcohol as well as water drinking in mice in a sex‐dependent fashion. Prenatal AR inhibition using the antagonist flutamide decreased adult male alcohol consumption. In contrast, prenatal AR activation by dihydrotestosterone (DHT) led to an increase in adult alcohol consumption in females. These effects were different in adult water drinking, flutamide increased water consumption in females and DHT increased water consumption in males. Prenatal flutamide reduced locomotion and anxiety in adult males but was ineffective in females. We found that prenatal AR activation controls adult levels of monoaminergic modulatory transmitters in the brain and blood hormone levels in a sex‐specific way. RNA‐Seq analysis confirmed a prenatal AR mediated control of adult expression of alcohol drinking‐related genes like Bdnf and Per2. These findings demonstrate that prenatal androgen activity is a risk factor for the establishment of alcohol consumption in adults by its organizational effects.
The effects of Mongolia's booming mining industry on its agricultural sector: A test for Dutch disease
Authors: Ge Wei , Kinnucan Henry W. 
Published: August 2017

AbstractDutch disease occurs when currency strengthening associated with a booming sector of an economy crowds out a lagging trade‐dependent sector. In this study, a Keynesian‐style model is specified to deduce hypotheses about how increased foreign direct investment (FDI) aimed at Mongolia's mining sector affects its agricultural sector. A key finding is that while econometric results suggest the increased FDI strengthened Mongolia's currency, its adverse effect on Mongolia's trade‐sensitive agricultural sector is not sufficiently strong to cause the sector to decline. Although Dutch disease was not detected, the posited mechanism clearly is important. Specifically, when currency strengthening is ignored the reduced‐form elasticity of agricultural value‐added with respect to FDI is 2.7 times larger than when currency strengthening is taken into account (0.103 vs. 0.038). Also, FDI‐induced currency strengthening causes the Keynesian multiplierto drop from 2.40 to 2.00 and the FDI multiplierto drop from 3.05 to 1.89.

Postpartum obstetric red cell transfusion practice: A retrospective study in a tertiary obstetric centre
Authors: Stephens Benjamin , Sethna Farah , Crispin Philip 
Published: August 2017

BackgroundTraditional management of anaemia due to postpartum haemorrhage (PPH) has relied upon salvage therapy with red cell transfusion. Recently published guidance recommends a change in approach toward holistic patient blood management.AimsTo determine whether postpartum red cell transfusion practices are consistent with best practice and to identify opportunities for improvement.Materials and methodsA retrospective audit of postpartum red cell transfusions was conducted at a tertiary level obstetrics unit. Relevant clinical and laboratory data were collected for all cases of postpartum red cell transfusions and PPH. Clinical decision making and appropriateness of transfusions were evaluated.ResultsAmong the 3235 women who delivered in 2013, 110 (3.4%) received a postpartum red cell transfusion. About 101 of the transfusions were associated with primary PPH. Overall PPH complicated 460 (14.2%) deliveries. Antenatal anaemia was identified as a major correctable risk factor for transfusion in women who experienced PPH (odds ratio 6.55, 95% CI: 3.17–13.6). Volume of blood loss and the aetiology of PPH were additional risk factors for transfusion. Transfusion was associated with lower birth weight and increased maternal length of stay. Transfusion triggers were more likely to be appropriate when transfusion took place in the operating theatre, within 12 h of delivery and when prescribed by anaesthetists. Post‐transfusion Hb levels were uniformly above target for all women transfused.ConclusionsA significant number of red cell transfusions were outside the recommendations of the new guidelines. Maximising red cell mass during pregnancy and improving transfusion practices were identified as opportunities for future improvement.

ABSTRACTDispersal is a process of central importance for the ecological and evolutionary dynamics of populations and communities, because of its diverse consequences for gene flow and demography. It is subject to evolutionary change, which begs the question, what is the genetic basis of this potentially complex trait? To address this question, we (i) review the empirical literature on the genetic basis of dispersal, (ii) explore how theoretical investigations of the evolution of dispersal have represented the genetics of dispersal, and (iii) discuss how the genetic basis of dispersal influences theoretical predictions of the evolution of dispersal and potential consequences.Dispersal has a detectable genetic basis in many organisms, from bacteria to plants and animals. Generally, there is evidence for significant genetic variation for dispersal or dispersal‐related phenotypes or evidence for the micro‐evolution of dispersal in natural populations. Dispersal is typically the outcome of several interacting traits, and this complexity is reflected in its genetic architecture: while some genes of moderate to large effect can influence certain aspects of dispersal, dispersal traits are typically polygenic. Correlations among dispersal traits as well as between dispersal traits and other traits under selection are common, and the genetic basis of dispersal can be highly environment‐dependent.By contrast, models have historically considered a highly simplified genetic architecture of dispersal. It is only recently that models have started to consider multiple loci influencing dispersal, as well as non‐additive effects such as dominance and epistasis, showing that the genetic basis of dispersal can influence evolutionary rates and outcomes, especially under non‐equilibrium conditions. For example, the number of loci controlling dispersal can influence projected rates of dispersal evolution during range shifts and corresponding demographic impacts. Incorporating more realism in the genetic architecture of dispersal is thus necessary to enable models to move beyond the purely theoretical towards making more useful predictions of evolutionary and ecological dynamics under current and future environmental conditions. To inform these advances, empirical studies need to answer outstanding questions concerning whether specific genes underlie dispersal variation, the genetic architecture of context‐dependent dispersal phenotypes and behaviours, and correlations among dispersal and other traits.

Published: August 2017

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.
