Investor Sentiments and Fama–French Five-Factor Premia

This study provides new insights to predict the excess return of a security. As if factor premia are getting influenced by the sentiments that means sentiments are ultimately affecting the excess return of a security. To meet the objective, a composite index developed by Baker and Wurgler is used as sentiment proxy. Monthly data are used from July 1965 to September 2015 in U.S. context. Granger casualty, Vector Autoregression (VAR), and Fama–Macbeth regression are applied to get the results. Results show that investor sentiments significantly drive the Fama factors’ premia: size premium and profitability premium. Sentiments also contain some information to explain the investment premia but fail to explain the market risk premium and value premium. Furthermore, results suggest that sentiments increase the explanatory power of model measured by R square. In short, this study suggests that investor sentiments play a role in explaining the Fama–French five-factor premia.
Measure of CLV Toward Market Segmentation Approach in the Telecommunication Sector (Vietnam)

This study is based on data used by a telecommunications industry over a period of 6 months, beginning July 1, 2018, until December 31, 2018. The approached model of customer lifetime value (CLV) was concerned on the sample size of 245,355 records made by cell phones of active prepaid subscribers. The aim of this article is to estimate CLV through survival function with adjusted variables enclosed, for example, marketing cost. To do this, a statistical model was used to predict the individual CLV and confirmed a different finding to some previous study, in which this new finding brings an important message that the telecom providers should take care of customer earlier before too late because after the 10th of tenure, the subscribers can churn the telecom operator’s service. The result of CLV is well supported to segment market. It will also benefit the telecom providers to maintain their market competitiveness.
The Role of International Factors in Electoral Volatility in Latin America: An Examination of Structural Adjustment

Does structural adjustment increase party system instability in Latin America? We employ the Latin American Presidential and Legislative Elections (LAPALE) database (http://www.lapaledata.com) and our own original data set for structural adjustment to assess the effects of structural adjustment and other economic, social, and political variables on legislative volatility in 18 Latin American countries during the period of 1982 to 2016. The results of our study indicate that structural adjustment results in higher levels of within-system electoral volatility and support a broad version of economic voting theory. Extra-system electoral volatility is driven primarily by institutional and demographic factors. Our findings also highlight the importance of disaggregating electoral volatility as within-system volatility and extra-system volatility appear to be largely driven by different factors, or in different ways by the same factors.
Exploring the Fundamental Factors of Digital Inequality in Bangladesh

Digital inequality is imperative to combat the perpetuation of national development and significantly exists in developing countries. Thus, the purpose of this article is to provide the underlying factors of creating digital inequality in Bangladesh. A mixed-method research approach was followed where both the qualitative and quantitative data were collected using focus group discussion (FGD), semi-structured interviews, and survey. The FGD and interviews were replicated with a total of 60 participants (each study with 30 participants), while 326 respondents participated in the survey study. The content analysis, word cloud, affinity diagram, and descriptive statistics were used to analyze the data. As an outcome, the studies revealed 23 factors that create digital inequality in Bangladesh. The factors were clustered into five groups (referred as elements) of digital inequality through an affinity diagram. The resultant elements of digital inequality were educational, infrastructural, social, economic, and usable design. The results reflect on what factors should consider ensuring the inclusion, adoption, and contributions of information and communications technology in Bangladesh, which in turn contributes to reducing the digital inequality in Bangladesh. As a practical contribution, this research provides an in-depth scenario of digital inclusion and exclusion in Bangladesh, and the underline factors of creating digital inequality, so that nongovernmental organizations and government organizations may take necessary initiatives toward each dimension of digital inequality. The results also include identification of future research agenda toward reducing digital inequality.
Is There a Digital Divide Between Urban Students and Migrant Students in China?

The digital divide is an important issue that has been addressed in the world for several decades. However, little attention has been paid to the special population that emerged in cities of developing countries: rural migrant workers. Previous studies have shown that family background is a potential determinant of digital inequality among schoolchildren. The study aims to explore whether the disadvantaged conditions of rural migrant workers have an impact on their children (i.e., migrant students). A questionnaire survey and multivariate analysis of variance (MANOVA) were conducted to examine the digital divide in information and communication technology (ICT) access, ICT usage, and ICT skill between urban and migrant students. We draw upon 1,230 fifth and eighth grade students from six urban public schools in China. Results indicate that all the indicators of the digital divide are statistically non-significant between the two groups, and the predictor of parental education level is invalid to an extent. Additional analyses suggest that providing equal opportunities like Chinese government for disadvantaged migrant students to enroll in urban public schools would reduce the digital divide between migrant students and urban students.
A New Polyhalogenated Monoterpene from the Red Alga Plocamium angustum

A new acyclic monoterpene, (E)-8-bromo-3,7-dichloro-2,6-dimethylocta-1,5-diene (4), has been isolated as the major monoterpene component of the red alga Plocamium angustum. A second component was the previously described cross-conjugated dienone (5).
Turnover among medical clowns early in their career

In recent years, several investigations of the medical clowning profession have appeared in the literature. However, few studies have focused on factors associated with turnover among medical clowns early in their careers. The current study examined whether individual differences in humor disposition predicted turnover behavior. Participants were 111 medical clowns in a three-phase longitudinal study. Humor disposition was measured in the first week of their training, clowns' job satisfaction two months later, and turnover six months after that. Results showed that humor appreciation decreased actual turnover through the mediating role of job satisfaction, whereas individual differences in humor creation directly decreased turnover. In addition, previous traumatic experiences moderated the associations between humor appreciation and turnover. Overall, our research findings support the notion that humor disposition can help predict which clowns remain in the hospital.
An epistemological analysis of the use of reputation as evidence

Rules 405(a) and 608(a) of the Federal Rules of Evidence allow the use of testimony about a witness’s reputation to support or undermine his or her credibility in trial. This paper analyses the evidential weight of such testimony from the point of view of social epistemology and the theory of social networks. Together they provide the necessary elements to analyse how reputation is understood in this case, and to assess the epistemic foundation of a reputational attribution. The result of the analysis will be that reputational testimony is extremely weak from an epistemological point of view, and that in many cases there are more reliable substitutes that achieve a similar purpose. The obvious fix, in my view, is to eliminate the use of reputation testimony to support or undermine the credibility, honesty, chastity or peacefulness of a witness
Developmental Human Resource Configuration, Unique Human Capital, and Employee Innovative Work Behavior: A Multilevel Moderated Mediation Model

Drawing on social exchange theory (SET), the purposes of this research are to investigate the effect that developmental human resource configuration (DHRC) has on employee innovative work behavior (IWB) and to examine the role that an empowerment climate plays in the relationship. The study assumes that knowledge workers perform IWB if they perceive the application of DHRC and the empowerment climate to support autonomy, information sharing, and team accountability. The data were collected from 37 R&D managers and 370 full-time R&D engineers, constituting 37 different high-tech companies in Guangdong province, China. Results show that a positive relationship between DHRC and IWB was found and was partially mediated by unique human capital. Findings also demonstrate that empowerment climates strengthen this relationship. The implications of the findings and future directions for research are further discussed.
A Game-Theoretic Analytical Approach for Fostering Energy-Saving Innovation in the Electric Vehicle Supply Chain

Motivated by the industrial observation that electric vehicle (EV) manufacturers are often fully or partially outsourcing some specific components, for instance, powertrains and battery systems, and rely on their suppliers’ energy-saving innovation to improve their own EVs’ comprehensive performances, this study builds an analytical framework to investigate how different cooperation modes affect the EV supply chain’s energy-saving performance and firms’ profitability. As a main barrier preventing potential consumers from purchasing EVs, the consumer range anxiety for EVs’ performance was incorporated into the analytical model. Three primary cases and one strategic alliance case are sequentially analyzed. The results show that the supplier always self-motivates to implement energy-saving innovation to improve the performance of the core component, and the EV manufacturer is always willing to participate in its supplier’s energy-saving innovation by sharing a fraction of the investment. Moreover, a strategic alliance between the manufacturer and the supplier can effectively improve the profit of the whole supply chain. This strategic alliance can be coordinated through a generalized Nash-bargaining mechanism.
Cross-Cultural Adaptation and Psychometric Properties of the Portuguese Coaching Life Skills in Sport Questionnaire

The Coaching Life Skills in Sport Questionnaire (CLSS-Q) is a 5-factor 36-item scale developed in the English language to assess the extent to which coaches are intentional in their approaches to teaching life skills through sport. To allow for usage of the CLSS-Q in Portuguese-speaking countries, the purpose of this study was to investigate the cross-cultural adaptation and the psychometric properties of the Portuguese version of the CLSS-Q (P-CLSS-Q). In Phase 1, the scale was cross-culturally adapted through consecutive stages of translation and back-translation, expert feedback, committee revision, and pretesting. In Phase 2, 753 youth sport coaches (i.e., 376 Brazilians and 377 Portuguese) completed the questionnaire. After randomly splitting participants into two independent samples, the translated and cross-culturally adapted questionnaire was subjected to an exploratory factor analysis and a confirmatory factor analysis. Other analyses were also applied to verify the instrument’s psychometric properties. The results led to a 5-factor 30-item scale with indications that the P-CLSS-Q has some evidence of validity in measuring the extent to which coaches intentionally teach life skills through sport in Portuguese-speaking countries. Future studies are needed to further investigate the psychometric properties of both the CLSS-Q and the P-CLSS-Q in other sociocultural contexts where coaches have varying levels of exposure to the concept of life skills and its implication for coaching practice.
Do Customer Discounts Affect Frontline Employees?

Customer discounts continue to be one of the most central promotional tools. While discounts effectively serve important corporate objectives, they may also exhibit additional unanticipated effects on internal stakeholders involved in the value creation process. This research examines the impact of customer discounts on frontline service employees. One experimental study and two field investigations are presented. The findings underline that customer discounts made salient by their redemption, frequency, and depth (i.e., magnitude) reduce frontline employees’ experienced task significance as well as their perceived appreciation by the firm. Discounts also exert destructive indirect effects on frontline employees’ workplace responses including their intrinsic motivation, ambivalent identification, and turnover intentions as mediated by task significance and appreciation. These indirect effects are for the most part driven by perceived appreciation, serving as a key mechanism in employees’ cognitive processing of customer discounts. The present findings provide first evidence that customer discounts can provoke undesired effects upon firms’ service workforce in tandem with fulfilling promotional objectives and stimulate the need for a better coordination between firms’ service and promotional activities.
A Dynamic Analysis of the Impact of Fiscal Adjustment on Economic Growth: Evidence From Pakistan

This study claims to be the first in assessing the short-run and long-run impacts of both the size and composition of fiscal adjustment on the growth in Pakistan. Empirical calibration has been made on Mankiw et al.’s model, while the Autoregressive Distributed Lag (ARDL) techniques of Pesaran et al. have been employed to carry out the estimation. To cure the problem of degenerate cases, the ARDL techniques have been augmented with the model of Sam et al. The analysis supports the hypothesis of “expansionary fiscal contraction” in the long run. The analysis reveals that the spending-based adjustment enhances the economic growth, whereas the tax-based adjustment would reduce the growth in the long run in the case of Pakistan. The Granger causality test indicates that the fiscal adjustments have been weakly exogenous, thereby allowing feedback effect from the economic growth toward the fiscal adjustment. Thus, the objective of sustained economic growth can be achieved through the spending-based consolidation measures.
Factors Affecting Campus Loans in Western China

Campus loans have become a part of the lives of Chinese college students. While such loans are convenient for students, they can also create considerable difficulties. In the context of unbalanced economic development between Western and Eastern China, this study aimed to understand the factors affecting the campus loan behaviors of college students in Western China. A sample of 568 undergraduate and graduate students from four universities in Western China was taken as the research object. Binary logistic regression and orderly logistic regression were used to study campus loan consumption factors. Students without state-subsidized loans were found to have stronger campus loan consumption intention and higher loan amounts, and recreational consumption was the main loan purpose. The factors affecting campus loan consumption included students’ family structure, parents’ education level, peer students’ consumption status, grade level, relationship status, and ability to assess loan risk. Based on the findings, suggestions are made for managing campus loan behavior from the perspectives of the individual, family, school, and government. This study can provide guidance for standardizing campus loans and adjusting college students’ consumption attitudes and behaviors.
Determining factors of labour market outcomes for recently graduated, underrepresented college students

This study examined the factors that determined labour market outcomes for recently graduated, underrepresented college students. Chile’s largest higher education institution, which has a significant number of first-generation students from more deprived social sectors, was considered. A quantitative methodology was applied using logistic and multinomial regression models. Occupational status and income level were chosen as the dependent variables and five dimensions of independent variables were considered: sociodemographic attributes, human capital, academic characteristics, personality traits, and work environment. The results indicated that males, graduates who worked during their studies, heads of households, graduates from technical-professional high schools, those who completed their higher education studies in a timely manner, those who worked for larger private companies, and those who worked in a different geographical region to the one in which they studied had better labour market outcomes. Suggestions for institutional practices to help underrepresented students have successful career transitions are discussed.
Review of the scientific evidence on the individual sensitivity to electromagnetic fields (EHS)

Abstract Part of the population considers themselves as sensitive to the man-made electromagnetic radiation (EMF) emitted by powerlines, electric wiring, electric home appliance and the wireless communication devices and networks. Sensitivity is characterized by a broad variety of non-specific symptoms that the sensitive people claim to experience when exposed to EMF. While the experienced symptoms are currently considered as a real life impairment, the factor causing these symptoms remains unclear. So far, scientists were unable to find causality link between symptoms experienced by sensitive persons and the exposures to EMF. However, as presented in this review, the executed to-date scientific studies, examining sensitivity to EMF, are of poor quality to find the link between EMF exposures and sensitivity symptoms of some people. It is logical to consider that the sensitivity to EMF exists but the scientific methodology used to find it is of insufficient quality. It is time to drop out psychology driven provocation studies that ask about feelings-based non-specific symptoms experienced by volunteers under EMF exposure. Such research approach produces only subjective and therefore highly unreliable data that is insufficient to prove, or to disprove, causality link between EHS and EMF. There is a need for a new direction in studying sensitivity to EMF. The basis for it is the notion of a commonly known phenomenon of individual sensitivity, where individuals’ responses to EMF depend on the genetic and epigenetic properties of the individual. It is proposed here that new studies, combining provocation approach, where volunteers are exposed to EMF, and high-throughput technologies of transcriptomics and proteomics are used to generate objective data, detecting molecular level biochemical responses of human body to EMF.
Bacteria in the amniotic fluid without inflammation: early colonization vs. contamination

Abstract Objectives Intra-amniotic infection, defined by the presence of microorganisms in the amniotic cavity, is often accompanied by intra-amniotic inflammation. Occasionally, laboratories report the growth of bacteria or the presence of microbial nucleic acids in amniotic fluid in the absence of intra-amniotic inflammation. This study was conducted to determine the clinical significance of the presence of bacteria in amniotic fluid samples in the absence of intra-amniotic inflammation. Methods A retrospective cross-sectional study included 360 patients with preterm labor and intact membranes who underwent transabdominal amniocentesis for evaluation of the microbial state of the amniotic cavity as well as intra-amniotic inflammation. Cultivation techniques were used to isolate microorganisms, and broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry (PCR/ESI-MS) was utilized to detect the nucleic acids of bacteria, viruses, and fungi. Results Patients whose amniotic fluid samples evinced microorganisms but did not indicate inflammation had a similar perinatal outcome to those without microorganisms or inflammation [amniocentesis-to-delivery interval (p=0.31), spontaneous preterm birth before 34 weeks (p=0.83), acute placental inflammatory lesions (p=1), and composite neonatal morbidity (p=0.8)]. Conclusions The isolation of microorganisms from a sample of amniotic fluid in the absence of intra-amniotic inflammation is indicative of a benign condition, which most likely represents contamination of the specimen during the collection procedure or laboratory processing rather than early colonization or infection.
Aesthetic practices in the climate crisis: Intervening in consensual frameworks of the sensible through images

Abstract Previous research has shown that Western visual journalism has represented climate change through certain repetitive and stereotypical imagery mainly consisting of catastrophic images of climate change impacts, images depicting technological causes and solutions, and images of politicians and activists. This imagery has proven to be distant, abstract, and ineffective in motivating personal engagement with climate change. In this article, we claim that visual journalism's representations of climate change are rooted in the consensual frameworks of human-centredness and consumption-centredness. Leaning on Jacques Ranciére's notion of “the politics of aesthetics”, we aim to challenge these frameworks. We suggest, with examples from visual arts, four aesthetic practices which could intervene in these frameworks: 1) revealing connectedness, 2) recognising agency, 3) compromising the attractions of consumerism, and 4) illuminating alternatives. We propose that visual representations, renewed through these aesthetic practices, could have an effect on how people connect to climate issues and imagine possibilities for agency in the climate crisis. Implementing these aesthetic practices would entail shifts in the sphere of visual journalism.
Disorders in Blood Circulation As a Probable Cause of Death in Dogs Infected with Babesia Canis

Abstract Introduction The purpose of the study was to investigate post-mortem changes in dogs infected with Babesia canis and to establish the probable cause of death of the affected animals. Material and Methods Cadavers of six dogs that did not survive babesiosis were collected. Necropsies were performed and samples of various organs were collected for histological examination. Results Necropsies and histological examinations revealed congestion and oedemata in various organs. Most of the dogs had ascites, hydrothorax or hydropericardium, pulmonary oedema, pulmonary, renal, hepatic, and cerebral congestion, and necrosis of cardiomyocytes. Conclusion These results suggested disorders in blood circulation as the most probable cause of death. However, the pulmonary inflammatory response and cerebral babesiosis observed in some of these dogs could also be considered possible causes of death. This study also showed a possible role for renal congestion in the development of renal hypoxia and azotaemia in canine babesiosis.
