E-learning in higher inclusive education: needs, opportunities and limitations
Authors: Meskhi Besarion , Ponomareva Svetlana , Ugnich Ekaterina 
Published: February 2019

Purpose
The purpose of this paper is to study the limitations, opportunities and conditions for the development of e-learning in the inclusive education system in the universities.

Design/methodology/approach
The paper reviews the literature dedicated to e-learning, its application and adaptation in higher inclusive education. Systemic and social approaches were applied to the perception of higher inclusive education for the purposes of this study. The principles of evolutionary economics and institutional theory were used for determining the possibility of using e-learning in higher inclusive education. The findings are confirmed by an empirical study of the integration of e-learning into the higher inclusive education system by the example of Russia.

Findings
It has been shown that the development of e-learning in the national higher education system and its perception by the higher inclusive education system depends on the level of development of social and information interrelation in the society. In addition, e-learning can only be used in higher inclusive education when it is interrelated with traditional learning. The efficiency of e-learning in higher inclusive education depends on the systemic institutional environment which was formed both at the level of the state and at the level of a particular university. In this case, the institutional environment should be focused not only on the development of e-learning and inclusive education, but also on their collaboration.

Practical implications
The results of the study, which identified special aspects, opportunities and limitations of e-learning in higher inclusive education, can be applied to improve its effectiveness both at the level of individual universities and at the level of formation of national strategies for the development of higher education.

Originality/value
Given the growing relevance of higher inclusive education in the contemporary world and the limited number of studies of adaptation and the use of e-learning in it, the results obtained can contribute to the implementation of strategic planning of this direction at the national and local levels.
Perception of ESG criteria by mainstream investors: evidence from Tunisia
Authors: Khemir Souhir 
Published: February 2019

PurposeThe purpose of this paper is to explore the perception of environmental, social and governance (ESG) criteria by mainstream investors in an emerging financial market, that of Tunisia, country at the origin of the Arab Spring.Design/methodology/approachA series of focus groups and semi-structured interviews were conducted with financial professionals.FindingsDespite efforts by the Tunisian state to promote CSR and ESG criteria since the outbreak of the revolution of January 14th, 2011, the results show that these criteria are fairly well known by our interlocutors. As part of an investment allocation decision, the ESG criteria are considered as secondary to financial ones. The three criteria are classified as follows according to their usefulness in the investment choices of financial professionals: corporate governance, social and environmental.Research limitations/implicationsIn addition to the subjective nature of the data collected, this research is limited to the input of only financial professionals. It does not inform us about ESG indicators that may influence the investment decisions of financial professionals, and thus this issue deserves further reflection.Originality/valueThis exploratory study sheds light on a little-explored topic in Tunisia, country at the origin of the Arab Spring. It contributes to the existing literature in the areas of investor behavior toward ESG criteria and adds to the limited literature in the area of emerging countries.
The moderating effect of international trade on outside director system in Korean firms
Authors: Nam Yoonsung , Kim Tae-Joong , Choi Wonyong 
Published: February 2019

PurposeThe purpose of this paper is to investigate the moderating effect of international trade on outside director system in Korean firms. The authors expected that Korean firms highly depending on international trade would mitigate the resource provision function of outside director system in order to reduce information asymmetry among global business partners. In addition, the authors tried to find out the functions of outside director system: the control function based on agency theory and resource provision function based on resource dependence theory.Design/methodology/approachThe authors tested the hypotheses by Poisson regression with 2011 and 2002 Korean-listed manufacturing firms. The dependent variable is the number of excessively appointed outside directors and independent variable is CEO type: family CEO or professional CEO. The moderating variable is the dependency on international trade measured by export proportion out of total sales.FindingsThe authors found that not control but resource provision function was a main role of outside director system in Korean firms. The authors also found negative moderating effect of dependency on international trade, which means that firms highly depending on global market tended to consider outside director system as control function, namely “global standard.”Originality/valueThis paper is the leading study that tries to analyze empirically the relationship between international trade and the function of governance mechanism; outside director system in Korean firms. It also confirms that Korean firms adopted outside director system on the basis of the resource dependence theory.
Homestead exemptions and efficiency
Authors: Carroll Deborah A. , Ivonchyk Mikhail , Larson Sarah Elizabeth 
Published: February 2019

Purpose
The purpose of this paper is to test the theory of optimal monitoring, which posits that more generous county homestead exemptions lower the incentive for residents to monitor school operations, thereby increasing inefficiency in service outcomes.

Design/methodology/approach
This research uses two-stage Simar and Wilson’s data envelopment analysis to assess county school districts’ efficiency in the state of Georgia for each year from 2007 to 2012.

Findings
Controlling for other factors known to be correlated with government efficiency, such as fiscal capacity and competition, this study finds evidence that higher property tax burdens resulting from lower county school district homestead exemptions, as a proxy of more intense citizens’ monitoring pressures, are associated with improved county school district performance efficiency. These results provide empirical support for the theory of optimal monitoring.

Practical implications
Increased government funding toward education is more likely to improve education outcomes if accompanied by efficiency control mechanisms. One such mechanism could be increased transparency of government operations and accountability of public officials.

Originality/value
This research uses a newer and more robust estimation of relative efficiency and analyzes a more common type of property tax exemption. This improves the internal validity and generalizability of the findings regarding the theory of optimal monitoring.
Budget preparers’ perceptions and performance-based budgeting implementation
Authors: Jalali Aliabadi Farzaneh , Mashayekhi Bita , Gal Graham 
Published: February 2019

Purpose
The purpose of this paper is to examine the reason for the failure of implementing performance-based budgeting (PBB) at Iranian public universities and research institutes (PURI). This examination focuses on the actors participating in the budget processes and their perceptions.

Design/methodology/approach
The study uses grounded theory and employs deep semi-structured interviews of budget preparers at Iranian PURI.

Findings
The results indicate a loose coupling between perceived and regulated budgeting process. This leads to budgetary slack as a barrier for authentic information flow and indeed PBB implementation. In the analysis of the results, the authors suggest some ways to improve the current situation of the budgeting processes at Iranian PURI.

Practical implications
Public organizations that desire to transform their budgeting system need to consider their actors’ perceptions regarding the budgeting process. By explicitly considering their perceptions the organization may be able to solve any loose coupling as a result of internal, external and behavioral conditions.

Originality/value
This research examines issues that arise in the transformation of organizational processes. The focus on budget processes is critical for organizations which receive most, if not all, of their operational funds from a central authority. This research highlights the role of budget actors’ perceptions in transforming the budgeting process. An important result of this analysis is documenting the existence of loose coupling in the current budgeting process at Iranian PURI. This loose coupling results in slack creation and restricts the implementation of a PBB system. Additionally, this loose coupling limits the flow of authentic information.
Prototypical brands and cultural influences
Authors: Jin Byoungho , Yang Heesoon , Kim Naeun 
Published: February 2019

Purpose
To extend the understanding of country image to the country whose image is less distinctive, the purpose of this paper is to examine two salient factors: one country’s prototypical brand and its cultural influence (i.e. Korean Wave) on shaping the country’s image in the context of Korea and its subsequent impact on product evaluation and purchase intention. Built on the prototype and schema theories, a research framework is proposed and empirically tested on two product categories (cosmetics and tires).

Design/methodology/approach
Data were collected from US consumers ages 20 and older and analyzed using structural equation modeling.

Findings
The findings largely supported the proposed framework with two additional paths (Korean Wave to product quality and Korean Wave to purchase intention). In both product categories, the findings confirmed that the image transfers from the prototypical brands (e.g. Samsung) to the country image (i.e., Korea), from Korean Wave to country image, and from the macro country image to the micro country image. The influence of the prototypical brand image was greater than that of the Korean Wave. However, some differences were found across product categories; the positive impact of the macro image on product quality evaluation was supported only for tires, not in the case of the cosmetics. The path from the Korean Wave to product quality evaluation was significant only for the cosmetics, and not for the tires.

Originality/value
These findings provided new theoretical perspectives for country image studies, and practical insights for companies, especially in countries whose image is less distinctive, to help develop effective marketing strategies in different product categories.
From doing to being: the tensions of systemic practice in social work – group reflective supervision in child protection
Authors: Bingle Leanne , Middleton Amanda 
Published: February 2019

This research aimed to consider the impact of introducing the systemic approach to child protection practice through the forum of group reflective supervision. A single case discussion was observed, recorded and transcribed and the data interpreted using thematic analysis (Braun and Clark, 2006). The social workers observed were trained in the systemic approach to foundation level. The data generated showed social workers using hypotheses to put forward ideas about a family shaped by systemic principles. However the inclusion of a pathologising discourse about a mother being blind to the sexual abuse of her daughter and an absence of self‐reflexivity suggested social workers were limited by linear thinking. The paper uses this data to suggest a tension between systemic practice and the child protection paradigm. The findings illustrate the challenge of occupying a systemic posture (the being) and the application of systemic concepts and techniques (the doing) in child protection. This paper recommends that systemic practice be taught and supported in social work to shape a more robustly reflexive systemic ‘being’ in the child protection context.Practitioner points

There are tensions in applying systemic principles in social work contexts that create unique challenges for practitioners

Without due attention to systemic epistemology in group reflective supervision, practitioners can rely too much on techniques to the detriment of reflexivity

Hypothesising in the child protection context can be useful in the work but can be constrained by institutional pressures

Without paying attention to circularity and reflexivity, hypotheses can recreate pathologising discourses
Antarctic Krill (Euphausia superba) Oil: A Comprehensive Review of Chemical Composition, Extraction Technologies, Health Benefits, and Current Applications

Published: February 2019

AbstractAntarctic krill (Euphausia superba) oil has been receiving increasing attention due to its nutritional and functional potentials. However, its application as a novel food ingredient has not yet been fully explored. This review summarizes the chemical composition, extraction technologies, potential health benefits, and current applications of krill oil, with the aim of providing suggestions for its exploitation. Krill oil is a unique lipid consisting of diverse lipid classes and is characterized by a high concentration (39.29% to 80.69%) of phospholipids (PLs) associated with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It also contains considerable amounts of bioactive minor components such as astaxanthin, sterols, tocopherols, vitamin A, flavonoids, and minerals. The current technologies used in krill oil production are solvent extraction, nonsolvent extraction, super/subcritical fluid extraction, and enzyme‐assisted pretreatment extraction, which all greatly influence the yield and quality of the end‐product. In addition, krill oil has been documented to have various health benefits, including anti‐inflammatory effects, cardiovascular disease (CVD) prevention, women's health, neuroprotection, and anticancer activities. Although krill oil products used for dietary supplements have been commercially available, few studies have attempted to explore the underlying molecular mechanisms to elucidate how exactly the krill oil exerts different biological activities. Further studies should focus on this to improve the development of krill oil products for human consumption.
Hyperoxygenation revitalizes Alzheimer’s disease pathology through the upregulation of neurotrophic factors

Published: February 2019

AbstractAlzheimer’s disease (AD) is a neurodegenerative disease characterized by Aβ‐induced pathology and progressive cognitive decline. The incidence of AD is growing globally, yet a prompt and effective remedy is not available. Aging is the greatest risk factor for AD. Brain aging proceeds with reduced vascularization, which can cause low oxygen (O2) availability. Accordingly, the question may be raised whether O2 availability in the brain affects AD pathology. We found that Tg‐APP/PS1 mice treated with 100% O2 at increased atmospheric pressure in a chamber exhibited markedly reduced Aβ accumulation and hippocampal neuritic atrophy, increased hippocampal neurogenesis, and profoundly improved the cognitive deficits on the multiple behavioral test paradigms. Hyperoxygenation treatment increased the expression of BDNF, NT3, and NT4/5 through the upregulation of MeCP2/p‐CREB activity in HT22 cells in vitro and in the hippocampus of mice. In contrast, siRNA‐mediated inhibition of MeCP2 or TrkB neurotrophin receptors in the hippocampal subregion, which suppresses neurotrophin expression and neurotrophin action, respectively, blocked the therapeutic effects of hyperoxygenation on the cognitive impairments of Tg‐APP/PS1 mice. Our results highlight the importance of the O2‐related mechanisms in AD pathology, which can be revitalized by hyperoxygenation treatment, and the therapeutic potential of hyperoxygenation for AD.
In Utero Exposure to Alcohol Impairs Reactivity of Cerebral Arterioles and Increases Susceptibility of the Brain to Damage Following Ischemia/Reperfusion in Adulthood
Authors: Cananzi Sergio G. , Mayhan William G. 
Published: February 2019

BackgroundMaternal consumption of alcohol produces abnormalities in the developing fetus and can contribute to an increased incidence of many cardiovascular‐related diseases. The first goal of this study was to determine whether in utero exposure to alcohol influences reactivity of cerebral arterioles in adult (12 to 15 weeks old) rats. The second goal of this study was to examine whether in utero exposure to alcohol increased the susceptibility of the brain to damage following an ischemic event in adult rats.MethodsWe fed Sprague Dawley dams a liquid diet with or without alcohol (3% ethanol) for the duration of their pregnancy (21 to 23 days). In the first series of studies, we examined reactivity of cerebral arterioles to endothelial nitric oxide synthase (eNOS)‐ (adenosine diphosphate [ADP]) and neuronal nitric oxide synthase (nNOS)‐dependent N‐methyl‐D‐aspartate (NMDA, and NOS‐independent agonists in adult rats before and during application of l‐NMMA. In another series of studies, we examined infarct volume following middle cerebral artery occlusion in adult offspring exposed to alcohol in utero. In both series of studies, we also determined the role for an increase in oxidative stress by feeding dams apocynin for the duration of their pregnancy.ResultsWe found that in utero exposure to alcohol reduced responses of cerebral arterioles to ADP and NMDA, but not to nitroglycerin in adult rats. In addition, treatment of the dams with apocynin prevented this impairment in cerebral vascular function. We also found that in utero exposure to alcohol worsened brain damage following ischemia/reperfusion in adult rats and that treatment of dams with apocynin prevented this increase in brain damage following ischemia/reperfusion.ConclusionsWe suggest that our findings may have important implications for the pathogenesis of brain abnormalities associated with fetal alcohol exposure.

AbstractDuring the first weeks of abstinence, alcohol craving in patients may increase or “incubate.” We hypothesize that Naltrexone (NTX) blocks this incubation effect. Here, we compared NTX effects on neural alcohol cue reactivity (CR) over the first weeks of abstinence and on long‐term clinical outcomes to standard treatment. Male alcohol‐dependent patients (n = 55) and healthy controls (n = 35) were enrolled. Participants underwent baseline psychometric testing and functional magnetic resonance imaging (fMRI) assessment of mesolimbic alcohol CR. Patients participated in a standard treatment program with the option of adjuvant NTX. They received another scan after 2 weeks of treatment. We found higher CR in several brain regions in patients versus healthy controls. CR significantly increased over 2 weeks in the standard treatment group (n = 13) but not in the NTX group (n = 22). NTX significantly attenuated CR in the left putamen and reduced relapse risk to heavy drinking within 3 months of treatment. Additionally, increased CR in the left putamen and its course over time predicted both NTX response and relapse risk. Carrier status for the functional OPRM1 variant rs1799971:A > G was considered but had no effect on NTX efficacy. In conclusion, NTX was most effective in patients with high CR in the left putamen. While the results from our naturalistic study await further confirmation from prospective randomized trials, they support a potential role of neural CR as a biomarker in the development of precision medicine approaches with NTX.

Published: February 2019

BackgroundIn 25% of affected babies, neonatal encephalopathy results from acute peripartum events, but rigorous review of these cases for quality improvement is seldom reported. New Zealand has maintained a national database of all babies diagnosed with Sarnat moderate and severe neonatal encephalopathy since 2010 under the Perinatal and Maternal Mortality Review Committee.AimsTo determine the rate of contributory factors, potentially avoidable mortality or morbidity, and to identify key areas for improvements to maternity and neonatal care among cases of neonatal encephalopathy following an acute peripartum event.Materials and methodsSarnat moderate and severe cases identified from the national collection of neonatal encephalopathy with a history of an acute peripartum event were reviewed using a standardised independent multidisciplinary methodology and a tool for assessing contributory factors and potential avoidability, with the addition of a human factors lens.ResultsForty‐seven cases from 2013 to 2015 were reviewed. The most common acute peripartum events were placental abruption (12) and shoulder dystocia (11). Contributory factors were identified in 89%, and the severity of outcome was potentially avoidable in 66%. Key modifiable areas included dynamic risk assessment, preparedness for obstetric and neonatal emergencies, best practice for maternal and fetal surveillance in labour, and documentation.ConclusionsThere is significant potential to improve quality and safety in acute peripartum care to reduce the risk of neonatal encephalopathy. Human factors were not well captured by the clinical notes or review tool. Attention to human factors by improved methodology can enhance review of neonatal encephalopathy.
