Capital Structure and Firm Performance: Evidence from Ghana Stock Exchange

The study examined the relationship between capital structure and firm performance, using secondary data. It covered all the 35 listed companies in accordance with the Ghana Stock Exchange (GSE) Fact Book 2009 over the period 2004 to 2008. Return on equity (ROE), return on assets (ROA) and return on total capital (ROTC) were used as explanatory variables. Capital structure was represented as short term debt (STD), long term debt (LTD) and total equity (TE). Three multiple regression models were utilized; hence series of regression analysis were executed for each model. Observations were that; STD, LTD, and TE respectively account for 8.6% of the variations of return on equity, 0.5% of the variations of return on assets and 3.2% of the variation of return on total capital. Important observed patterns in financing structure were: STD 52%, LTD 9% and EQUITY financing 39%. This has reemphasized the fact that listed companies are highly levered, and also highlights the importance of short-term debts over long-term debts in the financing of companies in Ghana. For every cedi of company financing in Ghana, listed companies employed 0.52pesewas of STD in financing their operations and for every cedi of company financing, listed companies during the study period employed 0.09 pesewas of LTD in their operations, but 0.39 pesewas of equity in financing their operations. This is so because the market for long term debt is not well developed in Ghana. The study observed that STD and TE have a significant positive relationship with ROE, ROA and ROTC but LTD has a significant negative relationship with ROE, ROA and TE. Keywords : Capital structure; performance; long term debt; short term debt; Ghana Stock Exchange, Sustainable development.
ParentsÃ¢ÂÂKnowledge, Attitude and Practice towards ChildhoodVaccination, Medina, Saudi Arabia 2017

Background: During the past few years, physicians in the kingdom were facing a growing number of parents who are questioning the safety and necessity of routine childhood vaccination because of some myths and misconceptions about vaccination. Objective: Our study aimed to assess knowledge, attitude and practice regarding childhood vaccination and their associated factors among saudi parents in AlMadinah region. Methods: An Observational, Cross sectional study was conducted during the period (January-march 2017) in AlMadinah, Saudi Arabia. Parents of children aged from 1 month to 7 years who lives in AlMadinah were invited to participate in filling electronic questionnaire. The questions were formulated based on questions and answers published by the Ministry of Health Saudi Arabia website. Data was collected by trained medical students of Taibah University from the parents. A representative sample of 614 of participants living in various area of AlMadinah was selected randomly. Results: 614 participants included in the study, Majority of them were mothers (86%). Most of them (58.1%) had their information regarding child vaccination from medical staff, followed by social media (17.4%) and books (14%). The results revealed that almost half of parents (N=310) had adequate knowledge regarding child vaccination. Attitude towards child vaccination was positive in more than half (N=346) of the parents. Most of the parents in the study (85.7%) believed that Compliance with the MOH vaccination schedule is very important but only 43% of them disagreed that vaccine doesn’t give child immunity against infectious diseases. Majority of parents had good practice toward vaccination (N=570, 92.8%) reported vaccination of their children according to the MOH vaccination schedule. Conclusion: The study showed that parents had an acceptable knowledge and attitudes on some aspects related to childhood vaccination. However, gaps in both knowledge and attitudes were identified. Most of parents had good practice toward vaccination. Educational interventions are required to improve parents’ knowledge on the vaccination.
ORIGINAL ARTICLE

In the present study, 20 chilli cultivars were characterized based on morphology as it serves as discrete identification indicator and also propose to evaluate cultivar diversity for yield related parameters. Among the 20 cultivars, different quantitative and qualitative morphological traits like, hypocotyl pubescence, hypocotyl colour, cotyledon leaf shape, cotyledon leaf colour, cotyledon leaf width and cotyledon leaf length were studied. A stem length to first bifurcation ranged from 10.80 cm (LCA-424) to 26.33 cm (LCA-620) among the 20 cultivars, taller and shorter stems, taller, wider plant, longer and wider leaves were noticed. Hence, this character could be used for varietal identification. Fruit, fruit length, fruit width, pedicel length, dry fruit weight, seed weight and seed size might be efficiently used for different the chilli cultivars. Fruit positions were divided into two groups viz., Pendent and Erect. Among them, maximum number of genotypes had pendent fruits while only one by Mycoteja produced erect fruits. The fruit yield varied from 83.95g to 295.10g with a mean of 146.82g. The maximum mean performance was observed for genotype LCA-625 (295.10 g/plant) followed by LCA-620 (249.93 g/plant) and LCA-424 (244.24 g/plant), while the minimum value was observed for LCA-305 (83.95 g/plant) preceded by LCA-960 (92.77 g/plant). The study has spawned some important morphological traits, which can be efficiently employed in differentiating the chilli cultivars for beneficial agronomic traits.
Identification of Locally Isolated Clostridium difficile from Rabbits

Clostridium difficile is one of the most important pathogens causing diarrhea and enteritis in rabbits as it causes pseudomembranous colitis that leads to intestinal damage and deaths. In this study, screening of rabbit farms from different localities in Egypt had shown rabbits suffered from diarrhea and enteritis to detect Clostridium difficile by ELISA, it revealed that five out of 50 samples (10%) were positive for it. These samples were further identification by cultivation and culture characters, microscopical examination, agglutination test, pathogenicity test and Polymerase Chain Reaction (PCR) by using specific primers for toxins genes (tcdA and tcdB). The results showing that three out of five isolates were confirmed as Clostridium difficile and concluded that these isolates causing pseudomembranous enterocolitis in rabbits and this disease unable to be treated by antibiotics, so it used for preparation of vaccine against the disease in rabbits.
Docking Prediction for Tumor Necrosis Factor-α and Five Herbal Inhibitors

Background & objectives: TNF-α (tumor necrosis factor-α), formerly known as cachectin, is a key cytokine that influences intermediary metabolism. The 5 herbal medicines curcumin, EGCG (epigallocatechin-3-gallate), sinapyl alcohol, SYRINGIN, and triptolide were experimentally found to be competitive inhibitors of the activities of TNF-α. In this study, we predicted and analyzed the ability of these 5 herbal medicines to inhibit TNF-α and identified binding sites for them. Methods: A homology model of TNF-α was constructed using SWISS-MODEL Workspace, its energy was minimized, and its quality was verified using PROCHECK, VERIFY3D, and ERRAT. The protein–ligand interactions were analyzed by simulating the docking of the 5 herbal medicines using Autodock 4.0. The binding sites were analyzed using Autodock 4.0 and LIGPLOT. Results: The results indicate that the 5 medicines are potent inhibitors of TNF-α. The 3 main binding regions and the common binding sites for the 5 medicines in the 3 binding regions were also identified. We also observed that curcumin and SYRINGIN docked at the receptor-binding sites of TNF-α. Covalent π–π aromatic interactions or π–cation interactions were found between sinapyl alcohol and curcumin and the TNF-α cytokine. Interpretation & conclusion: We found that the descending order of the degree of stability of TNF-α inhibition is curcumin > sinapyl alcohol > triptolide > SYRINGIN > EGCG. We predicted that sinapyl alcohol and curcumin are the strongest inhibitors of TNF-α because of the covalent bonds they form with TNF-α. The 5 herbal medicines tested in this study have a common binding site–Cys129–in TNF-α. TNF-α activation can be inhibited more efficiently when all 5 medicines are simultaneously used as a herbal medicine complex rather than when each is used alone.
The influence of job burnout, involvement and locus of control on job satisfaction: Some explorations from banking sector in Saudi Arabia

The present study is aimed at exploring the influence of job burnout, involvement and locus of control with job satisfaction among banking employees of kingdom of Saudi Arabia. The sample consisted of 274 employees selected randomly from various banks. A set of tools containing Job Burnout (Maslach and Jackson, 1981), Job Involvement Scale (Lodhal and Kejner, 1965), Rotter’s Locus of Control (1971), and Job Satisfaction (Singh, 1987)with biographical information blank were distributed to the bank employees to respond as per the instructions. The data were analyzed by means of ttest to see the differences between the comparison groups. The major findings of the present research revealed that: (i) the groups of low & high job burnout and involvement were found to differ significantly in terms of their mean job satisfaction(ii) internally control employees found significantly more job satisfaction than their externally control counterparts. The limitations and suggestions were also incorporated in the study. [Al-Kahtani, NS, Allam, Z.

Molar incisor hypomineralization in the permanent dentition of patients with unilateral or bilateral cleft lip and palate versus controls

Purpose: Molar Incisor Hypomineralization (MIH) is a congenital defect of unknown etiology that has been recently identified and is currently considered an increasing concern to dental clinicians. The defect involves enamel mineralization of one to four permanent first molars usually associated with similarly affected permanent incisors. The purpose of this retrospective study was to investigate the prevalence, severity, and location of MIH in the permanent molars and incisors of patients with unilateral and bilateral cleft lip and palate (CLP) as compared with controls. Methods: The sample consisted of intra-oral photographs of 71 CLP patients which were divided into two groups (unilateral versus bilateral cleft) and a modified Weerheijm ranking of enamel defects was compared to a control sample of 60 children without CLP who were age matched. Pearson chi-square tests were used to compare the groups for differences in the presence of hypomineralization, and Mantel-Haenszel chi-square tests were used to compare the groups for differences in MIH scores. Cochran-Mantel-Haenszel chi-square tests for stratified categorical data were used to compare the cleft and non-cleft sides for differences in the prevalence of hypomineralization and MIH scores within the CLP unilateral subjects. Significance was defined as p<0.05. Results: MIH scores were significantly lower for controls than for CLP bilateral and CLP unilateral groups (p<.0001). CLP bilateral had significantly higher MIH scores than CLP unilateral (p ≤ 0.01). The MIH scores were not significantly different between the cleft and non-cleft sides in the CLP unilateral subjects. However, two of the individual teeth – the maxillary-lateral (p=0.03) and maxillary central incisors (p ≤ 0.01) did show significantly higher scores for the cleft side as compared with the non-cleft side. Conclusions: Cleft patients are at higher risk of MIH than controls and children with bilateral clefts present with the most severe hypomineralization.

Cytochemical characterisation of photochemically formed , self-sustaining , abiogenic , protocell-like , supramolecular assemblies “ Jeewanu ”

Available online on http://www.ijlsci. in ISSN: 2320-964X (Online) ISSN: 2320-7817 (Print) Sunlight exposed sterilised aqueous mixture of some inorganic and organic substances reported by Bahadur and Ranganayaki provided an optimal physico-chemical environment for the self-assembly of molecules and photochemical formation of self-sustaining, abiogenic, protocell-like model ‘Jeewanu’. They possess an ordered structural configuration. They are capable of showing multiplication by budding, growth from within. The histochemical findings showed that the acidic material-like substances were localised in the central region, basic material-like substances were localised in extra central region while phospholipid-like substances were present in outer limiting surface of Jeewanu. The presence of RNA-like material is significant. In plausible prebiotic atmosphere the synthesized protocell-like model similar to Jeewanu was photoautotrophic in nature. They have an ability to convert solar energy into vital activities or useful forms.
Hand Gesture Recognition Using Principal Component Analysis

Nowadays actions are increasingly being handled in electronic ways, instead of physical interaction. From earlier times biometrics is used in the authentication of a person. It recognizes a person by using a human trait associated with it like eyes (by calculating the distance between the eyes) and using hand gestures, fingerprint detection, face detection etc. Advantages of using these traits for identification are that they uniquely identify a person and cannot be forgotten or lost. These are unique features of a human being which are being used widely to make the human life simpler. Hand gesture recognition system is a powerful tool that supports efficient interaction between the user and the computer. The main moto of hand gesture recognition research is to create a system which can recognise specific hand gestures and use them to convey useful information for device control. This paper presents an experimental study over the feasibility of principal component analysis in hand gesture recognition system. PCA is a powerful tool for analyzing data. The primary goal of PCA is dimensionality reduction. Frames are extracted from the Sheffield KInect Gesture (SKIG) dataset. The implementation is done by creating a training set and then training the recognizer. It uses Eigen space by processing the eigenvalues and eigenvectors of the images in training set. Euclidean distance with the threshold value is used as similarity metric to recognize the gestures. The experimental results show that PCA is feasible to be used for hand gesture recognition system.
Use of Extracts of Jatropha Curcas Leaf Formulated in A Simple Ointment Base in Wound Healing Activities: How Safe Is It?

The safety of the use of leaf extract of Jatropha curcas plant in different groups of wistar albino rats at different doses was investigated. Excision wound of about 21mm diameter size was inflicted on one side of the central trunk of the different groups of the albino rats, and different doses of the leaf extracts formulated into ointments were topically applied on the wound of the different groups for 21 days for wound healing and closure. The animals were sacrificed and the effect of the leaf extract on blood biochemistry and histopathological examination of the kidney and liver tissues were assessed using standard techniques. There were no statistical significant differences (p>0.05) in the result of the biochemical parameters: total protein, albumin, globulin aspartate amino transferase (AST) and alanine amino transferase (ALT), between the control and the experimental animals. Histopathological examination of the kidney and liver tissues showed that the animal had normal histological feature. The findings of this study showed that the leaf extract of J. curcas has no harmful effects.
Level of Awareness of Color Vision Disorders among the Public Secondary School Children in Emohua Local Government Area of Rivers State

Aim: To assess the level of awareness of color vision disorders among the public secondary school children in Emohua local Government area of Rivers State. Background: Colour vision disorders (CVD) also known as color blindness or color vision defects are a group of disorders associated with defective perception of colors. They are said to be one of the commonest genetic and inherited disorders observed in the human population. A normal person is said to require all the primary colors to match those within the spectrum. Any given cone pigment may be deficient and this is termed an anomaly, or absent, termed an anopia. Methodology: The study is a communitybased descriptive cross sectional study. Ethical clearance for the study was obtained from the Ethical committee of the hospital. Structured questionnaire were administered to all consenting students to determine awareness of color defects. All data generated were entered into a personal computer and then analysed with the help of a statistician using commercially available Statistical Package for Social Sciences Package version 21. Mean and standard deviations were determined for age. The age groups gender, other demographic distribution of the subjects amongst other were presented using frequency tables and charts Results: One thousand secondary school pupils showing a 100% response rate were interviewed and examined for Colour Vision Disorder during the study period. The mean age of the students was 14.3 ±1.8years with an age range between 9 and 20 years. Less than one-third of the students were aware of colour blindness (n = 234; 23.4%).
Height determination using hand length in Nigerian school children

Introduction. The anthropometric characteristics of 600 normal Nigeria School Children of ages between 5-10 years of Gbagyi tribe of Abuja, with no obvious deformities or previous history of trauma to the hand were selected for this study. Materials and methods. Of these children, males (n=300) with mean age of 7.10 ± 1.98, and females (n=300) with mean age of 7.68 ± 1.86) were investigated. The anthropometric characteristics of their height, age, weight, hand length, and body mass indices were measured, analysed statistically for any significant difference, and correlation between the parameters studied. Results.The results show some significant differences between the anthropometric parameters and a significant correlation (p< 0.001) between the height and hand length, and other parameters in both males and females. The study derived a linear regression and a multiple linear regression equations for Gbagyi School children of Nigeria from which height, age, weight, hand length and body mass index could be predicted if one factor is known. Conclusion. The results from the present study show that there was a positive correlation between height and hand length and other parameters indicating that height could be predicted using hand length, age, weight and body mass index among Gbagyi school children of Abuja-Nigeria.
Profile of Hysterectomy Specimens: Prospective Clinco-Pathological Study

Background: Hysterectomy is the most common operation performed by gynaecologists. Few studies have been done describing the pathological findings in hysterectomy specimens and while examining the relationship between the preoperative clinical indications and pathological diagnosis. Objectives: This study was undertaken to identify the most common pathologies in hysterectomy specimens and to correlate the findings with the clinical indications. Methodology: A total of 378 cases were studied over a period of two years. Specimens were formalin fixed and tissue was adequately processed from them. The sections were stained routinely with hematoxylin and eosin stain. Results: Menorrhagia (35.22%), fibroid uterus (26.63%) and uterovaginal prolapsed (13.05%) were the most common clinical indications for hysterectomy. The most common findings identified by histopathology were proliferative endometrium (39.41%) in endometrium, leiomyoma (31.48%) in myometrium, chronic cervicitis (50.26%) in cervix, ovarian cysts in ovaries and salpingitis in fallopian tubes. Conclusion: The histopathological examination confirmed the clinical diagnosis in majority of cases. However, it is mandatory that every hysterectomy specimen should be subjected to detailed histopathological examination to find missed pathologies to ensure better postoperative management.
