RBFN stochastic coarse-grained simulation method: Part I - Dilute polymer solutions using bead-spring chain models

In this paper, dynamic behaviours of dilute polymer solutions of various bead-spring chain models in shear flow are studied using a coarse-grained method based on the Integrated Radial Basis Function Networks (IRBFNs) and stochastic technique. The velocity field governed by the macroscopic conservation equations is determined by the IRBFN-based method, whereas the evolution of configurations of polymer chains governed by the diffusion stochastic differential equations are captured by the Brownian Configuration Field (BCF) approach. The system of micro-macro equations is closed by the Kramers' expression, which allows for the determination of the polymer stresses in terms of BCF configurations. In this work, all nonlinear effects in a BSC model such as hydrodynamic interaction and excluded volume are considered. Since the simulation requires a considerable computational effort, parallel calculations are performed where possible. As an illustration of the method, the start-up planar Couette flow is examined, in which the evolution of viscometric functions such as shear stress, the first and the second normal stress differences is assessed with various BSC models.
Educators’ roles in developing adolescent HIV/AIDS knowledge and attitudes within school culture

This paper reports on part of a study with the aim of exploring how Muslim learners’ knowledge and attitudes of HIV/AIDS were influenced by family and school culture. Findings from data collected during individual semi-structured interviews with the principals, Life Orientation educators, and school guidance counsellors are discussed. Reviewed literature supported the assumption that there were collaborative relationships within school culture that permitted children to learn about sexuality and HIV/ AIDS. Bandura’s Social Cognitive Theory and the Eight Gateways or “entry points” of school culture supported the data collection and reinforced the findings theoretically. A purposive sample was used for the qualitative case study within an interpretivist paradigm. The study indicated that the educators believed that the school should teach adolescents’ about HIV/AIDS. The aim of the school was to create awareness about non-risky behaviour in terms of HIV/AIDS among the learners. Educators were aware that this education did not always lead to positive behaviour changes. The school interventions had generally engendered positive values and dependable, safe relationships that helped adolescents to make responsible decisions in the face of HIV and AIDS. Educators did concede that despite the education at school, learners had to sometimes make difficult decisions as they were tempted to behave against the principles and education within the macro-society. Keywords: adolescents; AIDS; attitudes; HIV; entry points; knowledge; school culture; Social Cognitive Theory
Turnover intentions in Jordanian Universities: The role of leadership behaviour, organizational commitment and organizational culture

Article history: Received 2 August 2017 Received in revised form 13 November 2017 Accepted 2 December 2017 Evidence gathered in relation to academic situation in Jordan is alarming. About 3000 Jordanian academics left their job during the last 25 years. During the last eight years, twenty percent of working academics were planning to search for opportunities in other, mostly foreign, universities. This particular percentage is expected to increase to more than 60% by the end of 2020. Although low turnover rates are beneficial by opening doors for new talents and new ideas, high rates are disruptive and negatively impacts the image of academic sector in Jordan. To address this issue, this research endeavors to investigate the impact of leadership behaviour, organizational commitment and organizational culture on turnover intentions in Jordanian higher educational Institutes. The participants in this study were limited to Jordanian academicians who work in any Jordanian University. A structured questionnaire was adopted from the past literature and a total number of 300 questionnaires were sent, out of which 270 were collected back. SmartPLS version 2 was used to run SEM to analyze the model. Results showed that the entire exogenous variables have significant impact on the endogenous variable. The implication of this study is that managers should recognize the behaviour of leadership in which the behaviour that able to motivate the level of employee commitment to organization and reduce employee turnover intention.
Socio-demographic and health profile of schedule tribes of Velugodu, Andhra Pradesh, India -

Background: Scheduled Tribes live in unique physical, socio-economic and cultural environment, isolated from general population. The tribal population is at a higher risk of under-nutrition, because of the socio-cultural, socio-economic and environmental factors influencing the food intake and health seeking behavior. Inadequate health care facilities, illiteracy and socio-economic disadvantage among tribal populations perpetuate the vicious cycle of under nutrition. Methods: A pre-tested questionnaire containing information on household socio-economic and demographic particulars like type of family, religion, caste, age, gender, income, literacy, occupation was administered by paying house to house visits. A detailed clinical examination for assessment of nutritional status, history, signs and symptoms of current illness was carried. Results: 92% of the families are nuclear followed by joint, 3 generation and extended families. The average size of the family is 3.64. 97% practice Hinduism. The sex ratio is 987 females for 1000 males. 72% of the populations are illiterate. 40% of the populations earn their livelihood by collecting NTFP. 59% of under-fives, 30% of school going and adolescents and 60% of adults are under nourished. Conclusions: Socio demographic profile is similar to other Schedule Tribes and chenchu populations in India and other parts of Andhra Pradesh. Under nutrition is high among under-fives and adults. Scabies, anaemia and eruptive fevers are the common health problems after malnutrition.
Ownership Structure and Corporate Performance: Australian Evidence

This paper seeks to analyse the relationship between ownership structure and corporate performance for fifty firms listed on the Australian Stock Exchange during 2002-2003. The study initially tests a two equation model similar to that in the existing literature, but is distinguished from prior literature by subsequently reclassifying leverage. By categorising leverage as an endogenous variable, an examination of the relationship between ownership and performance is undertaken through ordinary least squares and two stage least squares analysis of a three equation econometric model. Interestingly, empirical results illustrate the fact that managerial ownership impacts negatively on firm performance which is consistent with the management entrenchment hypothesis.
Spreadsheet Error Detection: an Empirical Examination in the Context of Greece

The personal computers era made advanced programming tasks available to end users. Spreadsheet models are one of the most widely used applications that can produce valuable results with minimal training and effort. However, errors contained in most spreadsheets may be catastrophic and difficult to detect. This study attempts to investigate the influence of experience and spreadsheet presentation on the error finding performance by end users. To reach the target of the study, 216 business and finance students participated in a task of finding errors in a simple free cash flow model. The findings of the study reveal that presentation of the spreadsheet is of major importance as far as the error finding performance is concerned, while experience does not seem to affect students on their performance. Further research proposals and limitations of the study are, moreover, discussed.
Differences in risk perception among different groups in society and the impact of basic values and experiences of vulnerability

There are several groups in modern societies, such as immigrants, the disabled, the elderly, gays and lesbians, who do not experience their life and their life conditions as secure. This does not mean that structural variables such as age, social class, ethnicity, gender or disability alone can explain these differences. It is likely that individual life experiences such as hardship or discrimination also lead to variations in risk perception. This study sets out to find differences in perception in Sweden in order to investigate the social factors behind these differences and possible effects. The empirical analyses are based on a national survey (n=1540) about risk perceptions conducted in Sweden 2005/06. The results confirm differences in risk perceptions between minority groups and the majority population but the study also shows that earlier experiences and basic values explain some of these differences.
EFFECT OF EMPLOYEE RESOURCING STRATEGIES ON THE PERFORMANCE OF COMMERCIAL BANKS IN KENYA.

During the last decade, the Human Resource Management (HRM) field has shifted from a micro focus on individual HRM practices to a debate on how HRM as a more holistic management approach may contribute to the competitive advantage of the organization. The shift from examining single HRM practices to systems of practices entails focusing on the interrelationship between the various elements of the HRM system. This has created a lot of interest on the specific effect of human resources management strategies on performance. However, review of available literature indicates a serious lack of empirical studies designed to investigate whether a good alignment between human resources management and firm strategy has a positive or negative effect on performance of commercial banks in Kenya. This has led to a high desire by bank managers to know the contribution of human resource strategies to performance. This study, therefore, sought to investigate the effect of employee resourcing strategies on the performance of commercial banks in Kenya. The research adopted a mixed method approach which consisted of both qualitative and quantitative approaches. This allowed the two approaches to complement each other for better results. Specifically the study adopted the survey method. The study targeted a population of 46 banks and 2,738 employees who included: the CEOs, HR managers, Operations managers and other employees. The Nairobi head office of each bank was purposively sampled since strategies and policies are made at the headquarters and then cascaded to the branches. To ensure representation of the various subgroups in the population a sample of 349 employees was selected using stratified random sampling. Data was collected using self-administered questionnaires and interviews. Statistical data analysis involved first editing and coding the questionnaire and interview responses;
Not cool, but cosy - Five perspectives on Nordic city cultural policies

This article scrutinises the dominant discourses detected in the cultural policies of the Nordic capitals and looks into how these fit general understandings of the Nordic cultural model. The article applies critical discourse analysis to a variety of policy documents that describe the cultural policies of the Nordic capitals and leans towards theoretical frameworks of Nordic cultural policy and city cultural policy. Findings indicate that even though the cities’ cultural policies are inspired by discourses resembling narratives supported by the creative industries, cool capitalism, and economic instrumentalisation, these are not at the forefront of their policies. To the contrary, egalitarian aims, access, and participation are high on the agenda for all of the Nordic capitals where emphasis is on openness, access, inclusion, participation, and local cultural contexts rather than artistic excellence or economic incentives.

Deep binary prototype multi-label learning

kNN embedding methods, such as the state-of-the-art LM-kNN and SLEEC, have shown impressive results in multi-label learning. Unfortunately, these approaches suffer expensive computation and memory costs in large-scale settings. To fill this gap, this paper proposes a novel deep binary prototype compression (DBPC) for fast multilabel prediction. DBPC compresses the database into a small set of short binary prototypes, and uses the prototypes for prediction. The benefit of DBPC comes from two aspects: 1) The number of distance comparisons is reduced in the prototype; 2) The distance computation cost is significantly decreased in the Hamming space. We propose to jointly learn the deep latent subspace and binary prototypes within a unified framework. The encoding and decoding neural networks are employed to make deep binary prototypes well represent the instances and labels. Extensive experiments on several large-scale datasets demonstrate that DBPC achieves several orders of magnitude lower storage and prediction complexity than state-of-the-art multi-label methods, while achieving competitive accuracy.
Modelling Structural Breaks in the Us, UK and Japanese Unemployment Rates

In this paper we use a general procedure to detect structural breaks at unknown points in time which allows for different orders of integration and deterministic components in each subsample (see Gil-Alana, 2006). First, we extend it to the non-linear case, and show by means of Monte Carlo experiments that the procedure performs well in a non-linear environment. Second, we apply it to test for breaks in the unemployment rate in the US, the UK and Japan. Our results shed some light on the empirical relevance of alternative unemployment theories for these countries. Specifically, a structuralist interpretation appears more appropriate for the US and Japan, whilst a hysteresis model accounts better for the UK experience (and also for the Japanese one in the second subsample). We interpret these findings in terms of different labour market features.
A Revised Approach to Ice Microphysical Processes for the Bulk Parameterization of Clouds and Precipitation

Abstract A revised approach to cloud microphysical processes in a commonly used bulk microphysics parameterization and the importance of correctly representing properties of cloud ice are discussed. Several modifications are introduced to more realistically simulate some of the ice microphysical processes. In addition to the assumption that ice nuclei number concentration is a function of temperature, a new and separate assumption is developed in which ice crystal number concentration is a function of ice amount. Related changes in ice microphysics are introduced, and the impact of sedimentation of ice crystals is also investigated. In an idealized thunderstorm simulation, the distribution of simulated clouds and precipitation is sensitive to the assumptions in microphysical processes, whereas the impact of the sedimentation of cloud ice is small. Overall, the modifications introduced to microphysical processes play a role in significantly reducing cloud ice and increasing snow at colder temperatures and .
Clastogenic Analysis of Bauhinia variegata Bark Extract Using Micronucleus Assay in Mouse Bone Marrow Cells

Herbs have always been used as a common source of medicines, the Bauhinia variegata is an important herbal plant used in Aruveda as a traditional medicinal system of India. In the present investigations, the preventive effect of Bauhinia variegate bark extract was evaluated against cyclophosphamide induced micronucleus formation in the mouse bone marrow cells. The single ip administration of B. variegate bark ext at the dose of 125, 250 and 375 mg/kg body weight, 24 hours prior the administration of cyclophosphamide (at the dose of 50 mg/kg) have significantly prevented the micronucleus formations in dose dependent manner in bone marrow cells of mice as compared to cyclophosphamide group. However, B. variegate bark ext alone has not induced micronucleus formations in bone marrow cells as compared to control group. Therefore seems to have a preventive potential against CP-induced micronucleus formation in Swiss mouse bone marrow cells.
Enhanced Cellulase Production by a Novel Thermophilic Bacillus licheniformis 2D55: Characterization and Application in Lignocellulosic Saccharification

Effects of nutritional and physicochemical factors were investigated for cellulase production by the newly isolated thermophilic strain Bacillus licheniformis 2D55 (Accession No. KT799651). The optimum cellulase production in shake flask fermentation was attained at 60 °C, pH 3.5, 180 rpm, and in a medium containing untreated sugarcane bagasse and pre-treated rice husk at 7% (w/v), urea, 1 g/L, peptone, 11.0 g/L, Mg(SO4)2, 0.40 g/L, CaCl2, 0.03 g/L, Tween 80, 0.2% (w/v), and 3% inoculum. The highest carboxymethyl cellulase (CMCase), filtre paperase (FPase), and β-glucosidase produced under the optimized conditions were 29.4 U/mL, 12.9 U/mL, and 0.06 U/mL, respectively, after 18 h of fermentation. Optimization of the parameters increased the CMCase, FPase, and β-glucosidase activities by 77.4-fold, 44.5-fold, and 10-fold, respectively. The crude enzyme was highly active and stable over broad temperature (50 to 80 °C) and pH (3.5 to 10.0) ranges with optimum temperature at 65 °C and 80 oC for CMCase and FPase, respectively. The optimum pH for CMCase and FPase was 7.5 and 6.0, respectively. Saccharification of sugar cane bagasse and rice husk by crude cellulase resulted in perspective yields of 0.348 and 0.301 g g-1 dry substrate of reducing sugars. These results suggest prospects of thermostable cellulase from B. licheniformis 2D55 in application for bio-sugar production and other industrial bioprocess applications involving high temperatures.

"Network Structure in Risk-Sharing Arrangements: Evidence from Rural Tanzania"

Rural households in developing countries manage their exposure to risk and stabilize consumption through informal insurance arrangements. This paper approaches risksharing arrangements from a network perspective, investigating how risk-sharing networks are formed. When agents form a new link they also gain access to the larger network of partner’s friends and friends of these friends. I test the hypothesis that agents not only take into account the wealth of their direct partners, but also consider the benefits they would get from the net of indirect contacts. A network formation model with full heterogeneity among agents is first presented, following Jackson and Wolinsky (1996), an estimation procedure is then proposed and applied to data on rural Tanzania. Results show that agents take into account not only potential partners’ characteristics, but also their social connections. This suggests that risk sharing partners are not short-sighted, but actually consider the net advantage of potential links, evaluating also indirect benefits deriving from changes in their relative position with respect to all other agents. This paper contributes to both network theory and literature on risk sharing, in that it proposes an innovative procedure to estimate endogenous network formation models, and also provides evidence that indirect contacts have an explanatory value disregarded by all previous studies which are focused on direct relations only.
Ultra-fast outflows (aka UFOs) from AGNs and QSOs

During the last decade, strong observational evidence has been accumulated for the existence of massive, high velocity winds/outflows (aka Ultra Fast Outflows, UFOs) in nearby AGNs and in more distant quasars. Here we briefly review some of the most recent developments in this field and discuss the relevance of UFOs for both understanding the physics of accretion disk winds in AGNs, and for quantifying the global amount of AGN feedback on the surrounding medium.
Measuring the Effects of Monetary Policy in the Euro Area: The Role of Anticipated Policy

This paper investigates within a SVAR framework the effects of anticipated monetary policy in the euro area. Building on a procedure recently proposed by Cochrane which yields the response of output to an anticipated monetary policy impulse, we show that in the past twenty years anticipated monetary policy has had a considerable influence on output. Moreover, we compute the output effects of the systematic monetary policy response to aggregate demand and supply shocks and find that monetary policy pursues a counter-cyclical policy in response to demand shocks and, despite considerable lags, is pro-cyclical with regard to supply shocks.
