‘In this job, you cannot have time for family’: Work–family conflict among prison officers in Ghana

This article documents the experience of work–family conflict (WFC) among prison officers in Ghana. Although the term WFC has been used in relation to prison officers in the UK and the USA, the context of WFC in Ghana is unusual. In this predominantly collectivist culture, family responsibilities include obligations to the extended family. WFC is mainly unidirectional, with interference running from work to the family. Officers are thus impaired in fulfilling their family responsibilities, which consequently impairs their daily work and mental well-being. The ‘crisis controlling’ or ‘paramilitary’ organizational structure of the Ghana Prisons Service (GPS) makes it very difficult for the work domain of prison officers to accommodate family responsibilities. Female officers appear to bear a heavier WFC burden than male officers, mainly on account of their traditionally unpaid housekeeping role in addition to their paid employment in a masculine organizational culture. The findings are significant, as they show that the promulgation of family-friendly policies to alleviate WFC-associated stress lies in the hands of the GPS, since WFC emanates solely from the work domain.
Computational Prediction of the Reactivity Sites of Alzheimer Amyloid b-Peptides Ab40 and Ab42

Alzheimer’s illness is an advanced nervous syndrome that is connected to the existence of extracellular senile plaques. The extracellular senile plaques are predominantly composed of 40-42 residues of amino acid comprising polypeptides identified as b-peptides. The Theory of Chemical Reactivity together with MEDT (Molecular Electron Density Theory) and Conceptual DFT have been used to determine descriptors that permitted the forecast of the sites of reactivity of the Alzheimer amyloidb-Peptides Ab40 and Ab42 through QM:MM calculations with the ONIOM methodology.
SOA – The Link Between Modern Educational Technologies and Mobile Learning in the Higher Education Landscape

Abstract Modern educational technologies encompass a variety of variables such as people, processes, assets, environments, technology. These variables are part of a complex system which has some important properties and a final purpose: delivering learning material and keeping track of the recipient’s evolution and development. The purpose of this paper is to define the system of modern educational technologies with the help of its variables and internal or external processes as well as to find where mobile learning fits in this large system. From a technical point of view we want to analyze whether Service Oriented Architecture (SOA) is enough or proper to integrate mobile learning in this system. At the end we should be able to decide if dedicated mobile apps, or mobile friendly sites or a combination of those two are suited to deliver the results we are looking for with the support of SOA, if we consider the variety of devices and operating systems we are trying to integrate.
Controlled Islanding for a Hybrid AC/DC Grid With VSC-HVDC Using Semi-Supervised Spectral Clustering

As the last resort of emergency control, controlled islanding is an effective means of preventing fault propagation and a system-wide blackout. However, conventional ac transmission lines are unavailable to be employed for power exchange between these islands. To make full use of the dc power modulation capability of voltage source converter-based high-voltage direct current (VSC-HVdc) links, a new controlled islanding model is put forward for an ac/VSC-HVdc hybrid grid to minimize the composite power-flow disruption, in which the dc-terminals belonging to a VSC-HVdc link are placed in different islands. To solve this model, a semi-supervised spectral clustering-based approach is proposed by transforming the problem into a weighted undirected graph segmentation problem. The novelty of this paper is to find an optimal islanding solution in real time such that the power exchanges between islands are implemented via a VSC-HVdc link to reduce the generation-load imbalance. The simulation results on the IEEE 39-bus system and a real-world system verify the effectiveness and superiority of the proposed approach.
O Cf 00 T-1 O Situated Professional Development : The CATIE Model

This paper describes a qualitative study investigating the Capital Area Technology and Inquiry in Education (CATIE) model of situated professional development for technology integration in schools and classrooms. The CATIE model is called "situated" because it places educational technology experts in schools on an ongoing basis where they collaborate directly with teachers to develop and deliver technology enhanced lessons. Teacher learning about technology integration is thus situated in authentic technology integration activities. Unique about the CATIE model is that mentors work with schools and teachers on a long term, daily basis, that they work to incorporate technology use into existing curricula, and that they work in real classrooms directly with teachers and students. The CATIE program thus tends to reach most of the teachers and administrators in a school, and the results can be seen in terms of student learning, technology integration, and changes in school cultures. Findings from data collected to date, including monthly mentor reports, interviews with mentors, teachers, and school administrators, classroom observations, and student artifacts, are used to support discussion of the model.

Determination of stochastic vs. deterministic trend in quarterly GDP of Pakistan

Many economic and financial time series show evidence of trending behavior or non stationarity in the mean. An important econometric goal is determining the most proper form of the trend in the data. The transformations of series depend on whether the series is trend stationary or difference stationary. In this paper, study is conducted to declare the nature of trend component in quarterly GDP of Pakistan whether it is trend stationary or difference stationary. It is necessary to know, because trend stationary and difference stationary models imply very different short run and long run dynamics. We have explored the type of trend in GDP series by ADF unit root test and also support our arguments by empirical distribution instead of asymptotical ones i.e., bootstrapping test. The purpose of the paper is not only to investigate the type of trend in the series by conventional methods but also to motivate small distribution theory like bootstrapping techniques that can helps ones in selection of advocate model for observed series.
MOST photometry and modeling of the rapidly oscillating (roAp) star [gamma] Equulei

Aims. Despite photometry and spectroscopy of its oscillations obtained over the past 25 years, the pulsation frequency spectrum of the rapidly oscillating Ap (roAp) star γ Equ has remained poorly understood. Better time-series photometry, combined with recent advances to incorporate interior magnetic field geometry into pulsational models, enable us to perform improved asteroseismology of this roAp star. Methods. We obtained 19 days of continuous high-precision photometry of γ Equ with the Most (Microvariability & Oscillations of STars) satellite. The data were reduced with two different reduction techniques and significant frequencies were identified. Those frequencies were fitted by interpolating a grid of pulsation models that include dipole magnetic fields of various polar strengths. Results. We identify 7 frequencies in γ Equ that we associate with 5 high-overtone p-modes and 1st and 2nd harmonics of the dominant p-mode. One of the modes and both harmonics are new discoveries for this star. Our best model solution (1.8 M� ,l ogTeff ∼ 3.882; polar field strength ∼8.1 kG) leads to unique mode identifications for these frequencies (� = 0, 1, 2 and 4). This is the first purely asteroseismic fit to a grid of magnetic models. We measure amplitude and phase modulation of the primary frequency due to beating with a closely spaced frequency that had never been resolved. This casts doubts on theories that such modulation – unrelated to the rotation of the star – is due to a stochastic excitation mechanism.
Screening of Electrocatalysts for Photoelectrochemical Water Oxidation on W-Doped BiVO4 Photocatalysts by Scanning Electrochemical Microscopy

Oxygen evolution reaction (OER) electrocatalyst arrays for photoelectrochemical (PEC) water oxidation were fabricated on a metal oxide semiconductor photoelectrode, W-doped BiVO4 (BiVW-O). The electrocatalysts (IrOx, Pt, Co3O4) were prepared on a drop cast film of BiVW-O on fluorine-doped tin oxide (FTO) with a picoliter solution dispenser or photodeposition with light irradiation through an optical fiber. The prepared arrays were tested for PEC water oxidation in 0.2 M sodium phosphate buffer (pH 6.8) using scanning electrochemical microscopy modified with an optical fiber. Pt and Co oxide electrocatalysts showed an enhanced photocurrent for PEC water oxidation, while the other metal oxide catalysts including IrOx, which is known as an excellent water oxidation electrocatalyst on a metal substrate, were not effective. These results were confirmed with bulk film studies. A cobalt phosphate (Co-Pi) electrocatalyst was also tested as a bulk film on BiVW-O and showed improvement for PEC water oxidation. Prel.
Tourism's contribution to poverty alleviation: A community perspective from Tanzania

Taking a micro-level approach, this study questions whether the positive impacts of tourism often claimed at the macro level do indeed trickle down to the grassroots level to lift local people out of poverty. A case study of the local community in Barabarani village, Mto wa Mbu, Arusha, on Tanzania's popular northern tourist circuit, compares the perspectives of local residents and key decision-makers in the community. The extent to which tourism development has affected seven signifiers of poverty alleviation are examined: accessibility improvement (transport and communication), prices of goods and services, entrepreneurial training, income-generating projects, employment opportunities, general quality of life and household income. Most of the local community felt tourism development is having a positive impact and contributing to poverty alleviation, especially in terms of improving local facilities. However, there are variations, with household distance from the main road through the community being a determining factor.
Comparison of long-term changes in teenage body mass index between urban and other areas in Japan from 1986 to 2003

Japanese prefecture level panel data for the period 1986–2003 was used to analyze and compare the determinants of teenage body mass index (BMI) by sex and geographical area. Major findings through random effects estimation were as follows: (1) BMI consistently increased during the period in males aged 10–16 and in females aged 10–13 years, but not in 16-year-old females; (2) there was no difference in this trend between urban and other areas in most cases. However, the BMI of 16-year-old females was markedly lower in urban areas than in other areas. These findings suggest that girls who reach adolescence have a greater incentive to go on a diet and this tendency is more distinct in urban areas than in other areas.
GROWTH, YIELD AND POSTHARVEST QUALITY OF WAX APPLE AS AFFECTED BY NAPHTHALENE ACETIC ACID APPLICATION

Results of this study represent the first report of the effect of Naphthalene Acetic Acid (NAA) on the pre and post harvest quality of wax apple fruit. The wax apple trees were spray treated with 0, 5, 10 and 20 mg L-1 NAA under field conditions during 2008 to 2011. The experiments were carried out in Completely Randomized Design (CRD) with six replications. Leaf chlorophyll content, chlorophyll fluorescence, photosynthetic yield, net photosynthetic rate, drymatter content of leaves and total soluble solids and K+content of wax apple fruits were significantly increased after treatments with 10 mg L-1. Polygalacturonase activity significantly decreased with NAA treatments. The application of 5 mg L-1 NAA increased 27% more bud and reduced 42% less fruit drop compared to the control. In addition, higher protein and phosphate synthase activity of leaves, fruit set, fruit growth, larger fruit size and yield were recorded in NAA treated plants. In storage, treated fruits exhibited higher TSS and firmness and less weight loss, browning, titratable acidity, respiration and ethylene production than the control. It is concluded that spraying with 5 and 10 mg L-1 NAA once a week under field conditions produced better fruit growth and yield of the wax apple and maintained better fruit quality in postharvest storage.
Occurrence of Foot and Mouth Disease serotypes in trade cattle sold in Kwara state, Nigeria

Aims: Serological detection of Foot and Mouth Disease Virus (FMDV) serotype specific antibodies in trade cattle was conducted to determine occurrence of FMDV serotypes. Methodology and results: Cross-sectional study based on randomly sampled sera in cattle with unknown FMD vaccination history was carried out in five cattle markets in Kwara state over a period of 3 months (August-SeptemberOctober) in 2011. The sera were screened for antibodies to FMDV non-structural protein (NSP) using NS-Blocking ELISA Kit (PrioCHECK®) and serotype specific antibodies determined by a Solid-Phase Competitive ELISA. Out of 253 sera positive for FMDV serotypes, 74.3% (188) sera were from recovered and 25.7% (65 sera) infected trade cattle. The percentage serotype distribution was 18.6%, 46.6%, 21.3%, and 13.4% for serotype A, O, SAT1 and SAT2 respectively. However, combination of O and A, A and SAT2 as well as O and SAT2 occurred in some cattle. Serotype distribution according to location showed serotype O and SAT2 was highest in Ajasse and serotype A and SAT1 was highest in Bode Sadu and Ilesha baruba markets respectively. Conclusion, significance and impact study: Specific antibody detection confirmed FMD serotypes endemicity and ongoing infections in trade cattle within the Nigerian local markets. The identification of these circulating FMDV serotypes is necessary as a baseline for vaccination control strategy, in conjunction with international livestock trade regulation to enhance potentials of national dependence on beef exportation.
Evaluation of Integrated Horticulture-cum- Fish Farming in Malwa Region of Madhya Pradesh, India

In India, the farming community accounts for 80% under marginal and small farmer’s category1. Farmers under these categories are economically poor working in diverse, risk prone environments and with hardly sufficient to sustain their family. The declining trend in land holding per capita poses a serious challenge to the sustainability and profitability of farming. Considering the efficacy of this viable production system, the study was conducted in purposively selected ponds of farmers which had available space of the pond bundh used for production of horticulture produce. The trial was conducted minimum 06 replications were taken under farm field condition. Vegetable growing in the trellis and dykes is an additional component which helps in maximizing profit from unit area. The data were collected from each treatment for consecutively 03 years to judge the economic profitability and sustainability of the practice. It was observed that better production and sustainable economic return can be achieved through integrated production technology or with dyke vegetable cultivation in pond based integrated farming practices.

Isolation and characterization of H 2 S producing yeast to detoxify mercury containing compounds

The aim of the present study was to isolate yeast isolates from local environment for hydrogen sulfide production to detoxify mercury containing compounds. Preliminary twenty two yeast isolates from seventy were screened out by qualitative and quantitative assay having maximum ability to detoxify mercury. Zone of inhibition ranging from 7 - 14mm in well plate method and remediation of mercury in the culture medium ranging from 2 to 19µg/ml out of 20µg/ml HgCl 2 were observed. Mercury resistant isolates were further characterized for hydrogen sulfide production by growing them on Lead acetate (LA) medium. Maximum resistance to 100 µg/ml HgCl 2 yeast isolates showed minimum zone of inhibition (7- 9 mm) gave darker color on LA agar plates as compared to yeast isolates sensitive to mercury. On the basis of these results seven yeast isolates were characterized by 18S rRNA sequencing as Candida tropicalis (JF896569), Candida rugosa (JF896570-71), Pichia kudriavzvii (JF896572-73), Candida xylopsoci (JF896574) and Candida inconspica (JF896575). It is concluded from our studies that Candida xylopsoci and Pichia kudriavzvii have potential to detoxify mercury 95% and 94.5% respectively from the medium containing 20 µg/ml HgCl 2 within 36 hrs. Our findings suggest that both strains may have significant biotechnological role in the treatment of contaminants containing mercury before they discharge into the environment to make it friendly for living organisms.
Preparation of standardized rhinacanthus nasutus leaf extract by green extraction methods and evaluation of antifungal activity of its topical solution against trichophyton rubrum

A simple and practical green extraction method was described for preparation of rhinacanthin-C enriched Rhinacanthus nasutus leaf extracts. The extraction conditions, including extraction methods, alternative solvents, and leaf powder to solvent ratios, were determined to increase the amount of rhinacanthin-C in the leaf extracts. Microwave assisted extraction (MAE), an innovative green extraction method was determined as a suitable extraction method for rhinacanthin-C by comparison with the conventional extraction method including maceration and heat assisted extraction (HAE) methods. Ethanol, propylene glycol, glycerol that are generally used in a preparation of topical solution were evaluated to be a suitable alternative green solvent for extraction of rhinacanthin-C from the dried powders of R. nasutus leaves. The content of rhinacanthin-C in the leaf extract was determined by a reversed phase HPLC method. The suitable extraction conditions for preparation of rhinacanthin-C enriched R. nasutus leaf extracts were: employing of a solution of 25% v/v glycerol in ethanol as solvent, with a leaf powder to solvent ratio of 15: 100 (g/mL), and using maceration method for 72 h. The obtained extract was brownish solution with the content of rhinacanthin-C up to 1.79 mg/mL. The leaf extracts of R. nasutus were therefore prepared using these extraction conditions and standardized to contain rhinacanthin-C content of not less than 1.7 mg/mL. Three topical solutions containing the leaf extracts of R. nasutus as the active ingredient were formulated. The solutions were standardized to contain rhinacanthinC at a concentration of 0.1% w/v. Thymol and menthol were constituted as
Auto-Based BDEC Computational Modeling Framework for Fault Tolerant Nano-Computing

As CMOS transistors continue to miniaturize beyond 20nm dimension, semiconductor industries would not be able to confirm the firmness (stability) in the performance of those nano-based transistors. As miniaturization continues, variability in the performance of those transistors becomes very prominent and they will keep on growing, making the CMOS transistors less and less reliable. Subsequently, this will affect the performance and degrades the reliability of circuit systems made-up of those transistors. Thus, we are inevitably faced with the question of how to build a reliable computing system out of unreliable nano-based CMOS transistors. To tackle this problem, several computational modeling frameworks have been developed for quantifying reliability of integrated circuit systems. However, these modeling approaches have computational complexity, which increases exponentially with the size of circuit systems, making the reliability evaluation process of very-large-scale-integrated (VLSI) systems with hundreds of millions of transistors becoming very time consuming and intractable. Therefore, to speed up the reliability analysis of larger circuit systems, this paper looks into the development of an auto-based computational
Vertical integration in Mexican community forestry

While research has revealed the role of common property in risk diversification, poverty alleviation and resource management, few studies identify how common property management systems fill that role uniquely where market mechanisms or private property rights fail. To address that gap, the present research develops a consistent framework for analyzing local level production where community organizations have vertically integrated into the wood products industry, using common property forest as a source of raw material. Based on an incomplete contracting approach, it is argued that vertical integration allows local stakeholders to guide development within their community, provided that marginal productivity attains a certain level. Empirical results using a survey of 44 community governance regimes in Oaxaca, Mexico, show that communities are more likely to integrate forward into timber processing activities when they achieve initial levels of human and and social capital and increase labor productivity through higher forest land endowments. The model is extended to demonstrate that economies of scope arise between community-level timber production and non-timber benefits.
Revisiting the relationship between electricity consumption, capital and economic growth: Cointegration and causality analysis in Romania

The paper empirically analyzes, in the Romania’s case, the cointegration and causality between electricity consumption, capital and economic growth. The data set is covering the period 1980 - 2008. The results show the existence of bidirectional causality between electricity consumption and economic growth and between economic growth and capital use. In the same time, a unidirectional causal relation is also found from capital use to electricity consumption. The main finding suggests that electricity conservation policies may retard economic growth by reduction in electricity consumption. Moreover, in the opposite direction, from economic growth to electricity consumption, the fluctuations in economic growth may reduce demand for electricity.
