Abstract
This paper examined the accessibility of healthcare services to the people in the South Eastern Nigeria. The reason behind the study is to assess how the people make timely use of the health services according to their need. This is related to physical distance and travel time from service delivery point to the user and also how the healthcare services are able to cover the population of the study area. Data used were obtained from National Bureau of Statistics and the population commission. Data revealed that there are more privately owned health facilities in the area. It also revealed that the total number of hospitals (government, private and community owned hospitals put together do not adequately cover the population of the area they are meant to cover. These inadequate health facilities have implications for the total health status and wellbeing of the indigenes of the south east. Recommendations were made on how to tackle this inadequacy if the millennium development goals will be realised.
Contribution/ Originality
This study gives a clear picture of the healthcare facilities in the South East vis a viz the population of the area. It equally serves as a guide and reliable source of information to the government and other stakeholders so that adequate healthcare facilities be provided for the study area.

Various Influence of Active Сhemical Additives on Hydrogen and Hydrocarbons Combustion

Research Article
Author(s): N.M. Rubtsov, V.I. Chernysh, G.I Tsvetkov, B.S. Seplyarskii
Journal: International Journal of Chemistry and Materials Research

Abstract
It is experimentally revealed that the methane combustion inhibitor CCl4 shows no effect on the lower ignition limit of hydrogen combustion. It is established that small amounts (~10-1 %) of chromium hex carbonyl promote combustion of 2H2 + O2 mixture, which manifests itself in increase in the propagation velocity of the flame, thus inhibition of oxidation of isobutene by this additive takes place. Therefore the role of hydrogen atoms in hydrocarbon oxidation is not significant and may result at least in participating in longer reaction chains than in hydrogen oxidation. It means that the kinetic mechanism of inhibiting combustion of hydrocarbons by carbonyls suggested in the literature based on accounting for termination of hydrogen atoms should be refined.

Research Article
Author(s): Shaoying Zhang , Qin Li, Yulan Mao
Journal: Journal of Food Technology Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
 To prolong the shelf life postharvest jujube, the effect of carbon monoxide (CO) on senescence of postharvest jujube in relation to active oxygen metabolism was investigated. Jujubes were fumigated with CO gas at 5, 10, 20 or 40μmol/L for 1 h, and then stored for 30 days at room temperature. Changes in membrane permeability, malonaldehyde (MDA), H2O2, O2•− content, and activities of active oxygen metabolism associated enzymes including superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in fruit were measured. The results indicated that a little of CO could exhibit positive physiological effect on controlling senescence of winter jujube during storage. The study further showed that fumigating jujube fruit with 10 μmol/L CO could reduce increase of MDA content and the relative membrane permeability, effectively inhibit oxidative damage to lipids, decrease H2O2 and O2•− content and maintain high activities of SOD, CAT and POD. The present data suggest that exogenous CO treatment might delay the jujube fruit senescence by regulating active oxygen metabolism.
Contribution/ Originality
This study documents for the first time the effect of carbon monoxide (CO) on H2O2, O2•− content and activity of antioxidant enzymes (SOD, CAT and POD) in relation to active oxygen metabolism during senescence of postharvest jujube.

Abstract
Economic pressure and other pressure issues faced by small and medium sized companies (SMEs) require continuous improving of their capacities, of staff knowledge, of training and learning to survive or stay competitive. This issue is at the top of European, national and regional policies. But due to limited resources, often managers reduce learning activities and  using new technologies in their companies. Blended learning is a suitable way to learn in SMEs to increase their efficiency, to keep up competitiveness/surviving of the companies. Scenario-based learning is one method to be used in blended learning in order to improve learner engagement and problem understanding.Cloud computing is one of the emerging ICT trends in the past seven years. It has received much hype particularly in the past two years, with many companies considering the efficiency of cloud computing for their business, reduced costs, and easy access of data and particularly of new emerging ICT applications with little overhead.This paper contributes in the existing literature with results of interviews and case studies within projects aimed at problems of SMEs like suitable learning methods, advantages of cloud computing for SMEs efficiency and presents examples. The paper’s primary contribution is finding that blended learning is a suitable form for increasing competitiveness of SMEs and could be used also by introducing cloud services which will change the landscape of business also in SMEs in the next years.
Contribution/ Originality
The paper shows how European projects and cooperative work with participation of actors from different sectors can contribute to improving competitiveness and growth of SMEs

Dividend Policy Relevancy in Theoretical and Practical Economics

Research Article
Author(s): David Gordon
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The foremost purpose of this paper is to concisely explain to individuals teaching economics in an academic setting or using economics in a practical setting some of the basics of long run financial theory focusing on the dividend policy decision of a corporation. The main motivation for this study is based on observations of economists being very deficient in the discipline of finance especially in long run financial concepts. Many times practitioners or academics who are educated in the area of economics lack any type of background in finance and therefore are deficient with their knowledge of financial theory and applications. This disconnect prevents using many financial applications in their own classes, in their own businesses or with their own research. This paper serves as a primer to some of the long run dividend policy theories that individuals can use as a starting point to their additional research, study or use in teaching. Areas related to dividend policy and financial theory in general can be utilized by economists in academia and the private sector to enhance and advance their professional careers.
Contribution/ Originality
This study contributes in the existing literature by demonstrating the usual disconnect between the disciplines of finance and economics. The paper illustrates that economists can gain substantially from a basic knowledge of financial theory. The contribution here emphasizes the dividend policy decision that corporations must make.

S-Dimensional Assets Portfolio Evaluation

Research Article
Author(s): Luis F. Copertari
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
An approach to calculate the upper limit to any given portfolio with s assets (corporate stocks or government bonds) in it is provided, which does not require the relative weight of each asset in the portfolio. The value obtained is contrasted with the traditional weighting approach to calculate the portfolio’s value. The process followed is the scientific method, starting with observation and hypothesis and after analyzing two examples, a synthesis is performed by generalizing the concepts and the main thesis that the Pythagorean approach here proposed constitutes an upper limit for the portfolio’s value.
Contribution/ Originality
This study uses a new estimation methodology to calculate the upper limit value of a portfolio of assets without the need to incorporate the weight of each asset. If there are no weights assigned to each asset, this upper limit may be the only way to calculate the portfolio’s value.

Abstract
This paper examined the influence of gender on job satisfaction among library staff in private university libraries in Ogun State, Nigeria. The survey research design was adopted for the study. The study population was made up of 162 library staff in seven private university libraries. Sampling was enumerative as all members of the population were given the opportunity to participate in the study. A questionnaire was used for data collected which was analyzed using descriptive and inferential statistics. Findings revealed moderate level of job satisfaction across gender with male making up 27.2%, and females 35.1% of the total percentage of 62.3% for job satisfaction. Gender was found to have no significant influence on job satisfaction while other factors such as stringent conditions for promotion, denied access to benefits and lack of job security were identified as major constraints to job satisfaction. Based on the findings, the study recommends that library administrators adopt a policy of equal treatment for each gender and review the conditions attached to promotion, among others as measures for enhancing job satisfaction.
Contribution/ Originality
This study contributes in the existing literature on job satisfaction among librarians. While a number of studies have considered various other factors that may or may not contribute to librarians’ job satisfaction, this study considered the gender dimension.  It has revealed that gender does not influence librarians’ level of job satisfaction.

Abstract
This paper examines forests diversity, their use pattern and management in the Eastern Himalaya with a case study of Mizoram state. The Eastern Himalaya is one of the bio-diversity hotspots of the world where the forest diversity varies from the tropical rainforest to temperate and alpine types because of the altitudes. In the case study area i.e. Mizoram, forest types vary from tropical evergreen forests to montane and temperate with rich biodiversity. Forests are lifeline for livelihoods sustainability in Mizoram as it is the second largest source of income after agriculture. Total forestland is 90.68%. They are conserved by the community people and the state forest department. Even, the whole country received decrease in forestland; Mizoram has registered about 1.4% increase. A study on forest cover and changes in the eight sister states of the Eastern Himalaya during the last decades was carried out to penetrate the current status of forest. Data from the secondary sources were gathered largely from the Forest Survey of India (FSI) 1991, 2001 and 2011. Similarly, data from the Department of Environment and Forest, Government of Mizoram on forest diversity and their distribution were also collected. Further, wide range of discussion was made with the officials working in the forest department and with the local people to elaborate the other aspects of forest resources such as use pattern of forest products. Personal observations on forest diversity use pattern and management of forest resources in Aizawl district was also carried out.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Background. There is limited data on adjuvant treatment following surgery in patients with squamous cell carcinoma of the oral tongue. Aims. This retrospective study investigates prognostic value of different factors for local relapse-free survival (LRFS), regional relapse-free survival (RRFS), disease-free survival (DFS), and overall survival (OS) in patients with oral tongue cancer treated with adjuvant therapy following surgery. Materials and methods. Forty six patients with surgically treated oral tongue cancer were enrolled in the analysis. Adjuvant therapy consisted of postoperative radiotherapy (PO-RT) or postoperative concurrent chemoradiotherapy (PO-CCRT). All patients received three dimensional conformal radiotherapy. Weekly cisplatin was given as concurrent chemotherapy. Identification of prognostic factors for survival was done with univariate analysis. Multivariate analysis was used for factors confirmed as significant on univariate analysis. Results. Independent prognostic factors negatively influencing LRFS, DFS, and OS were ECOG performance status (p = 0.002, p = 0.013 and p = 0.022, respectively), overall stage (p = 0.011, p = 0.010 and p = 0.009, respectively), and pathologic nodal classification (p = 0.016, p = 0.011 and p = 0.015, respectively). Surgical margin status was an independent prognostic factor for RRFS, DFS, and OS (p = 0.032, p = 0.027 and p = 0.028, respectively). The type of adjuvant treatment used was independently prognostic for lower rates of LRFS and DFS (p = 0.029 and p = 0.010, respectively).Conclusions. Positive postoperative nodal status and close or positive resection margins had the most prominent negative prognostic influence on patients’ survival.  
Contribution/ Originality
This study is one of very few studies which have investigated potential prognostic factors that might influence treatment outcome exclusively in patients with squamous cell carcinoma originating from the oral tongue whose adjuvant therapy following surgery consisted of postoperative radiotherapy or postoperative concurrent chemoradiotherapy.

Abstract
Studies on Life tables of Spodoptera litura, were carried out on bidi tobacco cv ABD-101 under laboratory condition at 26 ± 1 °C temperature at Bidi Tobacco Research Station, Anand Agricultural University, Anand (Gujarat). The results on number of individuals survived during development revealed that there was no mortality during egg stage and the maximum durations of egg, larva and pupa were 4, 22 and 14 days, respectively. The number that survived from 100 eggs to adult emergence was 76. The pre-oviposition period was ranged from 41 to 42 days of pivotal age. Females contributed highest number of progeny (mx = 328.12) in the life cycle on the 45th day of pivotal age. The net reproductive potential (Ro) was 758.93 females with the mean length of generation period (T) of 45.67 days. The innate capacity for increase (rm) and finite rate of increase () were found to be 0.1462 and 1.1574 females/ female/ day, respectively with a weekly multiplication rate (λ)7 of 2.78 times. The hypothetical F2 females were found to be 575974.70. Results on per cent contribution of different growth stages in stable age distribution revealed that the egg stage contributed was maximum (52.64%), while the contribution of larvae, pupae and adults were 45.86, 1.36 and 0.12, respectively at stable age distribution of S. litura on tobacco cv.

Abstract
Aquaculture is becoming a very important source of income to many people as well as a source of protein in their diets. This study examined the influence of the entrepreneur and enterprise characteristics on small-scale cage fish enterprises in the Asuogyaman and South Dayi Districts. The research employed a descriptive-correlation survey design, which used quantitative method to collect data from 105 owners and managers of small-scale cage fish enterprises. The findings revealed that age of entrepreneurs influenced customer satisfaction as entrepreneurs experience also influenced growth in sales. It was observed that technical know-how, attitude towards work, and managerial skills, had a significant relationship with profitability, and customer satisfaction. Finally, age of the enterprise was found to have a significant relationship with growth in sales. In conclusion, all the variables had positive relationships with enterprise success, but not all the relationships were significant. It is recommended that cage fish farmers should be encouraged to invest more in technical education, which will help improve on the success of their enterprises. Furthermore, farmers should take precautions to reduce the risk of failure to increase their chances of success and survival.
Contribution/ Originality
The study contributes to existing literature to emphasize the relevance of human resource development in the areas of technical education and entrepreneurs’ attitude towards work to the success of cage fish farming. Therefore investment in human resource of entrepreneurs is necessary for the success of cage fish farmers’ enterprises.

Abstract
This paper investigates the variability of real business activities in the form of discretionary expenditures (accounts receivable, selling, general and administrative expenses, and net change in accruals), and the firm’s stock price performance in relation to the frequency of meeting or beating analysts’ earnings forecast.  In addition, the study investigated the relationship between the firm’s stock price performance, and the variability of these financial statement accounts.  The objective was to examine if these selected financial statement of accounts could be used by management to manipulate earnings in order to meet and/or beat analysts’ earnings forecasts so as to enhance the firm’s stock performance.  The study found that there is a significant difference between the variance of SG&A, NCA and stock returns of the firms that meet and/or beat the analysts’ forecast and those that do not.  It was also found that there is a significant difference in stock returns based on meeting and/or beating the analysts’ estimate. 
Contribution/ Originality
This study adds to the literature by demonstrating another avenue for earnings management that does not rely on the Jones’ model.  It also shows how the variance of financial statement accounts can be used to detect earnings management.  Finally, this paper shows that the change in stock price as a result of earnings announcement is temporary.

Abstract
Post Beijing Conference has seen tremendous efforts by governments especially in developing countries such as Ghana to improve access to education at all levels and most critically to females. Over the last two decades, Ghana has put in place various interventions tailored to increasing female school enrolment and reducing the gender gap in education. Commendable results have been achieved. For instance, there is gender parity at the basic education and an increasing enrolment figures at the tertiary level. What has over the years been overlooked is how female students cope on campus as a result of combining academic work with other roles. The study is situated within this context, and using the seven roles framework and the bio-psychosocial model, it assesses the challenges pregnant-students face and how they cope at University of Cape Coast campus. A combination of accidental and snowball sampling techniques were employed to contact 62 respondents as well as conduct 12 in-depth interviews. More than 90 percent of the respondents were married. Common among the roles played include individual, occupational, and conjugal roles. These contributed to various challenges including psychological, socio-economic and academic-related challenges. Emotion-based coping strategies were mostly adopted to deal with the challenges. In the short term, the University must develop interventions to assist pregnant-students to cope effectively on campus, while in the long term, develop a policy to that effect.

Abstract
This study was undertaken to ascertain the extent to which career guidance/counselling can serve as a tool for functional education and graduate employability. The study was conducted in Kogi State University, Anyigba.  A sample size of 500 was selected using stratified and simple random sample techniques, across the faculties of the final year students. The data collected from the sample were analyzed using simple percentage and mean. The results obtained among others were as follows; that the level of guidance and counselling services among the students in the university was not significantly high. There was significant influence in academic performance of students who had received guidance and counselling services as against those who had not. That guidance services serves as motivation for acquisition of skills. It was recommended that guidance and counselling services should be improved upon, and that guidance/counsellors should be employed by university authority. Priority should be focused on the attitude of students toward guidance service and that guidance/counselling services should be given at the point of entry and should be guided to point of graduation. A functional guidance counselling units should be established in all tertiary institution in Nigeria. Fund should be raised by the federal/state governments to maintain guidance units in all our university campuses. By so doing, students focus on their course of studies and those who need change of course to suite their career choice could be assisted through follow up, on graduation they could easily be employed and become functional and useful to themselves and society at large.
