Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.411096
Abstract: In lower middle-income countries like Ghana, it is common to find low contraceptive use among adolescents with corresponding high pregnancy outcomes. Evidence points to the fact that the use of contraceptives prevents maternal, neonatal and infant deaths, but in most lower middle-income countries, socio-cultural practices inhibit adolescents’ use. Ensuring the uptake of family planning among adolescents is deemed a necessary means of reducing maternal, neonatal and infant mor-tality. This manuscript seeks to provide contextually relevant approaches to satisfying family planning needs of adolescents in a population lacking it. We employed a qualitative study design from an interpretive paradigm with phenomenology as the methodology to understand societal attitudes towards family planning delivery to adolescents, so as to arrive at contextually appro-priate ways of providing family planning to this needy group. Focused group discussions and in-depth interviews techniques were used in data collection among adolescents, relevant commu-nity opinion leaders and family planning & health services providers. Themes that emerged from data analysis with respect to “perspectives on family planning care delivery to adolescents” and “best ways in addressing adolescents’ family planning needs” are presented, followed by discussion of the issues emerging. A significant and encouraging finding of the study was that opinion leaders and healthcare providers viewed family planning as a means of protecting adolescents against pregnancies and their complications. A key recommendation is for policy makers and political leaders to enact legislations that enable adolescents to have friendly family planning service delivery in all places and at all times.

Abstract: This study describes community members’ knowledge of Ebola Virus Disease (EVD), their attitudes and preventive practices. A mixed methods approach was used. A random sample of 1028 community members aged 15 - 65 years was interviewed in a quantitative survey. This was complemented with a qualitative study involving 24 opinion leaders who were carefully selected. The study was conducted in Kintampo North and South districts of Ghana from August 2014 to October 2014. 83% of respondents had heard of EVD, but 62.5% did not know the duration between the time of infection and onset of clinical symptoms. The most popular symptom mentioned spontaneously was bleeding through body orifices (48.6%). Majority of respondents mentioned handshake or skin contact as a mode of transmission (57.3%) and reduced contact with bats as a means to prevent the spread of EVD (58.1%). Knowledge of transmission of body fluids such as faeces, blood or urine was low (<10%), though this varied significantly by socio-demographic group. Majority (94%) of respondents acknowledged that EVD was a serious disease, however, only 58% saw themselves at risk. Current preventive behaviours included: improved hand hygiene (83%) and avoidance of handshakes and physical contact with people (81%). Community members in the Kintampo districts have high level of awareness of EVD, but important gaps in knowledge of EVD still exist, especially concerning body fluids as a mode of transmission. There is the need to intensify educational messages as part of Ghana’s preparedness towards a potential EVD outbreak.
Rule of Fives: Identifying Critical Misalignment of Strategic Choices in Organizational Design  [PDF]
Timothy Nerenz
Open Journal of Business and Management (OJBM) , 2019, DOI: 10.4236/ojbm.2019.71003
Business leaders, consultants, teaching professionals, researchers, and academic theorists have long recognized the importance of strategic choice alignment as a determinant of firm performance and as a measure of strategic leadership competence. But how do we know which organizational elements need to be aligned? How do we determine if those elements are aligned or misaligned, and how do we prioritize misalignments which most urgently need to be corrected? This paper proposes a ten-element best-fit alignment stack of strategic choice meta-frameworks drawn from the author’s expe-rience as both a business leader and graduate school professor and offers a simple assessment mechanism that identifies the most critical misalignments in a firm.
Health-information seeking on the Internet and current smoking status: Evidence from the national health interview survey  [PDF]
Timothy S. Killian
Open Journal of Preventive Medicine (OJPM) , 2012, DOI: 10.4236/ojpm.2012.23042
Abstract: Two research questions were addressed. First, what are the differences between internet searchers and non-searchers for health-related information among current and former smokers? Second, does searching the internet for health-related information predict current smoking status in a multivariate model that controls for variations in sociodemographic and family characteristics? Data collected from 10,929 current and former smokers who participated in the 2009 National Health Interview Survey showed significant differences in sociodemographic and family characteristics between searchers and non-searchers. Importantly, searching the internet for health-related information made an independent contribution to the prediction of current smoking status in a multinomial logistic regression model. This study is significant in that it utilized a nationally representative sample to examine the correlation between internet use and smoking behavior and supports ongoing efforts of public health advocates to continue their efforts in developing and delivering online smoking cessation programs.
Powder River Basin Coal: Powering America  [PDF]
Timothy J. Considine
Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.48063

Powder River Basin (PRB) coal in Wyoming and Montana is used to produce 18 percent of the electricity consumed in the United States. Coal production from the PRB more than doubled between 1994 and 2009. PRB coal companies produced greater amounts of coal at declining real prices over much of this period through investment in equipment and production systems that achieved massive economies of scale. The bulk of PRB coal is shipped to the middle part of America from Texas in the south to Michigan in the north and New York in the east. States that consume significant amounts of PRB coal have electricity rates well below the national average. The largest industrial users of electricity are in these regions. Replacing PRB coal would require almost 5.5 trillion cubic feet of natural gas per year, representing a 26 percent increase in demand. Such an increase in gas consumption would increase prices for natural gas by roughly 76 percent. In such a world, U.S. energy users would pay $107 billion more each year for electricity and natural gas. Hence, by using PRB coal, the U.S. economy avoids $107 billion per year in higher energy costs. Estimates reported in the literature indicate that the gross environmental damages from PRB coal production are $27 billion. Hence, the net social benefits of PRB coal are $80 billion per year. Given the large size and low cost of these reserves, PRB coal will likely supply societal energy needs well into the future as long as the public and their elected officials are willing to accept the environmental impacts in return for the substantial economic benefits from using PRB coal.

The Moral Value of Yorùbá Moonlight Tales  [PDF]
Timothy Adeyemi Akanbi
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.44040
Abstract: Considerable attention has been given to oral literature in Yorùbá language. Oral literature, as regards children lullaby, children rhymes and moonlight tales are not left out. However, most of the earlier writings on folktales are centred only on the compilation of these oral literatures. However, Isola (1995) and Akinyemi (2004) have made some attempts in explaining the educational significance of these oral literatures. While Isola (1995) looks at children lullaby and children rhymes in relation to the intellectual and social development of the African child, Akinyemi’s focus is on oral literature as it relates to the indigenous education for children. Our focus in this paper is on the moral value of this oral literature to both the youth and the adult. We also opine that moonlight tales, because of their moral values, should be included in the curriculum of both the primary and secondary schools. This paper, which is a deviation from the moonlight stories mentioned in Akinyemi (2004), does not look at the pranks of the tortoise but human beings. Lessons, which the stories pass across, are highlighted.
A Descriptive and Syntactic Analysis of Àhàn Pronouns  [PDF]
Timothy Adeyemi Akanbi
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.45057
Abstract: This paper examines pronouns in Àhàn, a language spoken in the Southwest Nigeria, specifically in Òmùò-Èkìtì, Ekiti East Local Government Area. In this language, the tone born by a pronoun is conditioned by the environment where it occurs. In other words, a first person pronoun subject can be a high, mid or a low tone. We also observe that in this language, pronoun can change its morphological form when it occurs in a particular syntactic environment as against the other. We shall also show, in the paper that pronouns in Àhàn inflect for tense.
Fundamental Architecture and Performance Analysis of Photofission Pulsed Space Propulsion System Using Ultra-Intense Laser  [PDF]
Robert LeMoyne, Timothy Mastroianni
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.34055

Photofission enables a unique capability for the domain of non-chemical space propulsion. An ultra-intense laser enables the capacity to induce nuclear fission through the development of bre- msstrahlung photons. A fundamental architecture and performance analysis of a photofission pulsed space propulsion system through the operation of an ultra-intense laser is presented. A historical perspective of previous conceptual nuclear fission propulsion systems is addressed. These applications use neutron derived nuclear fission; however, there is inherent complexity that has precluded further development. The background of photofission is detailed. The conceptual architecture of photofission pulsed space propulsion and fundamental performance parameters are established. The implications are the energy source and ultra-intense laser can be situated far remote from the propulsion system. Advances in supporting laser technologies are anticipated to increase the potential for photofission pulsed space propulsion. The fundamental performance analysis of the photofission pulsed space propulsion system indicates the architecture is feasible for further evaluation.

Project New Orion: Pulsed Nuclear Space Propulsion Using Photofission Activated by Ultra-Intense Laser  [PDF]
Robert LeMoyne, Timothy Mastroianni
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.44071

Project New Orion entails a pulsed nuclear space propulsion system that utilizes photofission through the implementation of an ultra-intense laser. The historical origins derive from the endeavors of Project Orion, which utilized thermonuclear devices to impart a considerable velocity increment on the respective spacecraft. The shear magnitude of Project Orion significantly detracts from the likelihood of progressive research development testing and evaluation. Project New Orion incorporates a more feasible pathway for the progressive research development testing and evaluation of the pulsed nuclear space propulsion system. Photofission through the application of an ultra-intense laser enables a much more controllable and scalable nuclear yield. The energy source for the ultra-intense laser is derived from a first stage liquid hydrogen and liquid oxygen chemical propulsion system. A portion of the thermal/kinetic energy of the rocket propulsive fluid is converted to electrical energy through a magneto-hydrodynamic generator with cryogenic propellant densification for facilitating the integral superconducting magnets. Fundamental analysis of Project New Orion demonstrates the capacity to impart a meaningful velocity increment through ultra-intense laser derived photofission on a small spacecraft.

Decay of Pressure Fluctuation in the Hyporheic Zone around a Cylinder  [PDF]
Timothy Calappi, Carol Miller
World Journal of Mechanics (WJM) , 2016, DOI: 10.4236/wjm.2016.64013
Abstract: Erosion around a submerged cylinder is a well-studied problem, and is of particular interest in bridge pier scour applications. Particles erode when lift and drag forces overcome a critical threshold. These forces are typically studied from above the water-riverbed interface and are related to geometry and surficial processes. The present study maps hyporheic pressure fluctuations as they are related to surface water velocity fluctuations. Relatively, high-pressure events in the subsurface promote a destabilizing force from within the riverbed and increase the potential for the mobilization of sediment. Differential pressure transducers were fitted within a vertical cylinder in a movable bed flume. The pressure ports were flush with the cylinder surface and below the water-sand interface. The three-orthogonal components of velocity were recorded synchronously with differential pressure measured over a 15 mm depth. As expected, results show decay in pressure fluctuations as a function of depth.
