Effects of Academic Stress and Perceived Social Support on the Psychological Wellbeing of Adolescents in Ghana  [PDF]
Franklin N. Glozah
Open Journal of Medical Psychology (OJMP) , 2013, DOI: 10.4236/ojmp.2013.24022
Abstract: The purpose of this study was to examine how academic stress and perceived social support influence the psychological wellbeing of Senior High School students in Ghana. Two hundred and twenty six male and female students participated. The general health questionnaire, student life-stress inventory and perceived social support from family and friends scales were used to assess psychological wellbeing, academic stress and perceived social support respectively. The results indicated that perceived social support buffered the effects of academic stress on psychological wellbeing. Girls reported higher scores on perceived social support but reported more depression. Boys reported higher academic stress and better psychological wellbeing, and these have been attributed partly to the socialisation role of gender. These results have policy implications in respect of the creation of a cordial school environment as well as encouraging a healthy interpersonal relationship between adolescents and their family and friends with the aim of reducing academic stress appraisal which is inimical to the psychological wellbeing of adolescents.
Heterotrophic and Autotrophic Soil Respiration under Simulated Dormancy Conditions  [PDF]
Daniel Beverly, Scott Franklin
Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.53024
Abstract: Carbon cycling research has increased over the past 20 years, but less is known about the primary contributors to soil respiration (i.e. heterotrophic and autotrophic) under dormant conditions. It is understood that soil CO2 effluxes are significantly lower during the winter of temperate ecosystems and assumed microorganisms dominate efflux origination. We hypothesized that heterotrophic contributions would be greater than autotrophic under simulated dormancy conditions. To test this hypothesis, we designed an experiment with the following treatments: combined autotrophic heterotrophic respiration, heterotrophic respiration, autotrophic respiration, no respiration, autotrophic respiration in vermiculite, and no respiration in vermiculite. Engelmann spruce seedlings and soil substrates were placed in specially designed respiration chambers and soil CO2 efflux measurements were taken four times over the course of a month. Soil microbial densities and root volumes were measured for each chamber after day thirty-three. Seedling presence resulted in significantly higher soil CO2 efflux rates for all soil substrates. Autotrophic respiration treatments were not representative of solely autotrophic soil CO2 efflux due to soil microbial contamination of autoclaved soil substrates; however, the mean autotrophic contributions averaged less than 25% of the total soil CO2 efflux. Soil microorganism communities were likely the primary contributor to soil CO2 efflux in simulated dormant conditions, as treatments with the greatest proportions of microbial densities had the highest soil CO2 efflux rates. Although this study is not directly comparable to field dormant season soil CO2 effluxes of Engelmann spruce forest, as snowpack is not maintained throughout this experiment, relationships, and metrics from such small-scale ecosystem component processes may yield more accurate carbon budget models.
Microcredit Schemes: A Tool for Promoting Rural Savings Capacity among Poor Farm Families: A Case Study in the Eastern Region of Ghana  [PDF]
Mercy Asamoah, Franklin Manu Amoah
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.31003
Abstract: Savings mobilization is crucial for any viable economic and investment activity. In rural agricul-ture, the ability to save or to mobilize capital in cash at bank or stock of wealth is a major prerequisite as the collateral for accessing bank loans. The ability to save among rural poor households is however, difficult due to their low income levels and inability to make personal savings commitment. According to Yunus (2000) [1], failure of traditional financial institutions to extend credit to the poor is the single most important reason for the perpetuation of poverty. Nevertheless, since the early 1980s, microfinance scheme has been identified as a useful tool that can effectively mobilise savings among poor households. Yunus (2003) [2] indicated that micro-credit schemes have developed unique characteristics in terms of unconventional approaches, organizational and lending procedures that have resulted in high rates of repayments, savings mobilization and the ability to nurture a culture of commitment and self-reliance of poor people. The objective of this study was to assess the role microfinance plays in savings mobilization among farm households, analyse the extent of savings mobilized by participants and evaluate the conditions for membership of such schemes. A total of 212 respondents in organised cocoa farmer Associations since 2010 in the Eastern region were interviewed using formal questionnaires. The results indicated that the microfinance model had helped the respondents, mainly small-scale cocoa farmers, to mobilize substantial savings in a convenient and tailor made way. The majority who did not have any savings culture before joining the schemes were surprised about their savings potential through the group concept. Also, the schemes allayed the fear of the participants to take credit from financial institutions with high (over 95%) repayment culture using peer support, group guarantee and social capital generated through the formation of associations. They also had easy access to farm inputs such as fertilizer to maintain their cocoa farms because of their savings mobilization. It is concluded that microfinance model is a potential tool that promotes savings culture which gives access to credit for small-scale cocoa farmers to purchase farm inputs to increase productivity and enhance their livelihood.
A Poisson Solver Based on Iterations on a Sylvester System  [PDF]
Michael B. Franklin, Ali Nadim
Applied Mathematics (AM) , 2018, DOI: 10.4236/am.2018.96052
Abstract:
We present an iterative scheme for solving Poisson’s equation in 2D. Using finite differences, we discretize the equation into a Sylvester system, AU +UB = F, involving tridiagonal matrices A and B. The iterations occur on this Sylvester system directly after introducing a deflation-type parameter that enables optimized convergence. Analytical bounds are obtained on the spectral radii of the iteration matrices. Our method is comparable to Successive Over-Relaxation (SOR) and amenable to compact programming via vector/array operations. It can also be implemented within a multigrid framework with considerable improvement in performance as shown herein.
Visiones del regionalismo y la regionalización en América del Sur en el nuevo milenio
Molina,Franklin;
Revista Venezolana de Economía y Ciencias Sociales , 2007,
Abstract: this article aims to revise the concepts of regionalism and regionalization within the particular context of south america. four waves of regionalization or integration are distinguished, beginning in the 1960s and culminating with the current tendencies. in its course the article examines the changes in mercosur and the andean community, together with the process of construction and negotiation of the incipient south american community of nations.
De la evidencia al desempe?o: cómo fijar prioridades y tomar buenas decisiones
White,Franklin;
Revista Panamericana de Salud Pública , 1998, DOI: 10.1590/S1020-49891998000700022
Abstract: in today's world, with its respect for the medical sciences and demand for administrative accountability, health institutions are publicly responsible for their actions to an unprecedented degree. making decisions and setting priorities on the basis of politics or unvalidated expert opinions is no longer acceptable. instead, proven efficiency and effectiveness, as demonstrated by scientific evidence under continuous evaluation, are essential to decision-making. the need for applying rational criteria makes it necessary to explore a fundamental question: how can we promote critical reasoning within health services so as to adequately set priorities, make proper decisions, and launch effective interventions? in other words, how can we move from evidence to performance and why set priorities at all?
Capacity-building for health research in developing countries: a manager's approach
White,Franklin;
Revista Panamericana de Salud Pública , 2002, DOI: 10.1590/S1020-49892002000900004
Abstract: research may be viewed as rigorous inquiry to advance knowledge and improve practices. an international commission has argued that strengthening research capacity is one of the most powerful, cost-effective, and sustainable means of advancing health and development. however, the global effort to promote research in developing countries has been mostly policy driven, and largely at the initiative of donor agencies based in developed countries. this policy approach, although essential, both contrasts with and is complementary to that of research managers, who must build capacity "from the ground up" in a variety of health service settings within countries and with differing mandates, resources, and constraints. in health organizations the concept of research is broad, and practices vary widely. however, building research capacity is not altogether different from building other kinds of organizational capacity, and it involves two major dimensions: strategic and operational. in organizations in the health field, if reference to research is not in the mission statement, then developing a relevant research capacity is made vastly more difficult. research capacities that take years to develop can be easily damaged through inadequate support, poor management, or other negative influences associated with both internal and external environments. this paper draws from key international research policy documents and observations on the behavior of research and donor agencies in relation to developing countries. it examines capacity-building primarily as a challenge for research managers, realities underlying operational effectiveness and efficiency, approaches to resource mobilization, and the need for marketing the research enterprise. selected examples from south asia and latin america and the caribbean are presented.
Optimización del plan básico de numeración e identificación en la red pública de transmisión de datos de Venezuela
Planchart,Franklin;
Revista de la Facultad de Ingeniería Universidad Central de Venezuela , 2008,
Abstract: an issue of current interest is that of control over systems of enumeration. such control concerns internet protocol (ip) numbers and domain names. protocols such as electronic number mapping, rfc 2916 (enum), aimed at separating the current telephone structure control scheme through the integration of ip networks and the public switching telephone network (pstn), based on the format of e.164 numbering, has not been implemented due to restrictions in granting one root of level zero by the internet corporation for the assignation of names and numbers (icann), for the creation of the e164.arpa domain, parallel to in-adr.arpa (root of the present dominion). the solution put forward here has been to recommend the creation of the plan for world-wide numeration based on ipv6 that introduces the concept of nationality in the ipv6 format. we also suggest the creation of one system of names based on national codes that would allow us to address and consult the domain name system (dns) of countries (at the level of telephone services) without having to go for a root system controlled by any one nation. that is to say, we propose a division of the dns. this alternative combines the enum protocol, portability and mobility through the connection between the pstn with the ipv6 network. the introduction of ipv6 allows us to introduce the universal mobile telecommunications system (umts), on a large scale and to benefit from the x digital subscriber line (xdsl) platform. the idea is to eliminate the network address translation (nat), through the substitution of the current numeration plan based on ipv4.
O conflito distributivo e a teoria da infla??o inercial
Serrano, Franklin;
Revista de Economia Contemporanea , 2010, DOI: 10.1590/S1415-98482010000200007
Abstract: this paper briefly discusses a few aspects of the evolution of the theory of inertial inflation in the brazilian literature. some of its main shortcomings are analyzed from a sraffian perspective, that sees cost push inflation as being based on conflicting claims over the distribution of income.
Juros, cambio e o sistema de metas de infla??o no Brasil
Serrano, Franklin;
Revista de Economia Política , 2010, DOI: 10.1590/S0101-31572010000100004
Abstract: interest rate, exchange rate and the system of inflation target in brazil. in the consensus view of the brazilian system of inflation targeting, the core of inflation is due to demand shocks; the rate of interest is set to control demand; and some variation in the exchange rate happens as "collateral damage". in this note we argue that in reality core inflation comes from cost push; the interest rate affects the exchange rate; changes in the exchange rate affect costs and prices; it is the effect of interest rates on demand that is the "collateral damage" and that the long run anchor of the system is low average real wage rigidity.
