Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1105038
The purpose of the study was to determine if there were differences in the perceptions of primary and secondary school teachers’ classroom assess-ment practices in region one in Jamaica. Seven research questions guided the study. An analytic survey research design was used to answer the research questions. A stratified random sampling method was used to select 225 teachers. However, a total of 157 (64 primary & 93 secondary) school teachers participated in the study. Data were collected through the use of a web-based questionnaire which had an overall reliability coefficient of 0.749. The findings showed that closed-book test, portfolio, multiple-choice, short answer, restricted essay, and fill-in-the-blanks were popularly used by the teachers. The findings also showed that there were significant differences among the teachers on the following arranging test items according to types and writing specific instructions, informing students about the areas that will be assessed, administration of assessments, grading assessment, explaining how scores were derived, giving students the opportunity to appeal their grades, and using the results of the statistical analyses to improve assessment practices. Based on these findings recommendations were made on how to improve teachers’ assessment practices.

Students’ success in the online environment seems to be inextricably linked to learner characteristics and experiences related to the use of information and communication technologies. An increasing number of in-service teachers are being encouraged to pursue continuing education via the use of these technologies. This study examined learner characteristics, experiences, and technological capacities possessed by 55 in-service teachers pursuing postgraduate studies using the online/blended learning approach. The paper was also aimed at determining if there are differences in the views expressed by the male and female in-service teachers on learner characteristics, experiences, and technological capacities. Five research questions guided the study. A questionnaire was used to collect data, and descriptive and inferential statistics were used for the analysis. The findings indicated that a majority of the in-service teachers possessed the characteristics and technological capacities needed to succeed in the online learning environment. The findings also showed that most of the in-service teachers had the characteristics needed to do online/blended learning, had basic technology capabilities needed to succeed in an online/blended learning programme, and the in-service teachers had different experiences with the online/blended learning approach. Recommendations were towards making the in-service teachers’ experiences more desirable.
Sexual Practices and Perceptions of Risk among Undergraduate Students Attending a Tertiary Institution in Jamaica: A Pilot Study  [PDF]
Andrea Pusey-Murray, Cynthia Onyefulu
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101261
Abstract: This paper describes the sexual practices and perceptions of risk among undergraduate students attending a tertiary institution in Jamaica. The study was guided by six research questions. To answer these research questions, a descriptive survey design was used for the study. A total of 63 undergraduate students were selected using the stratified random method. Data for the study were collected through the use of a questionnaire and focus group discussion. The data were coded and entered into SPSS version 20. Simple descriptive statistics (frequency and percentage, cross-tabulation and t-test) were used to analyze the data. The results showed that over two- thirds (85%) of the students were sexually active and that the male students initiated their sexual activities earlier than the female students. It was revealed that 12.6% of the respondents had their first sexual encounter when they were less than ten years old. The findings of this study showed that a greater number of females (41.0%) reported using a condom on their first sexual encounter when compared to 20.6% of the male undergraduate students. Although 88.8% of the respondents reported seeing the promotional advertisement about safe sex, 11.2% stated that the advertisements were not convincing, for example they stated: “it did not convince me, and needed to show more than the risk”, and “not doing enough to scare young people about STD”. This has serious implications for how prevention messages are fashioned. The study indicates the need for partnerships to improve the STI/HIV risk reduction interventions in Jamaica. Based on the sexual practices identified in this study, undergraduates at this particular university are at risk of contracting STIs making them susceptible to cervical cancers, infertility and unwanted pregnancies. Based on the findings and their implications, six recommendations were made on how to use the platforms that will appeal to this group of undergraduate students in practicing safe sex.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104903
The online appointment system at the university health centre was intro-duced by the University of Technology (UTech), Jamaica management in 2014. The purpose of this study was to determine the users’ views of the online appointment system, as well as their views about the services offered at the university health centre. To achieve this purpose, a descriptive research design was used to answer three research questions. The con-venience sampling method was used to select 50 participants (30 students & 20 university staff members), who visited and used the health centre services. A questionnaire with an internal consistency of 0.87 was used to collect data from the participants who gave their consent. The findings showed that a majority of those who used the online appointment system were satisfied. The general view of the users about the health services provided at the health centre was positive. The results of the Fisher Exact test showed that there were differences in the views of the students and the staff in their responses to two items that measured the services provided by the doctors, and the access to the different services. Recommendations were made on how to improve the online appointment system as it relates to timing, and quality of services provided.
“It’s a Wild Ride”: A Phenomenological Exploration of High Maternal, Gestational Weight Gain  [PDF]
Cynthia L. Murray
Health (Health) , 2014, DOI: 10.4236/health.2014.618293
Abstract: High maternal, gestational weight gain is associated with high birthweight, large-for-gestational-age birthweights, cesarean delivery, child overweight, and short- and long-term postpartum weight retention. In this phenomenological study, the meaning and experiences of weight gain for pregnant women with high gestational weight gain were investigated. Data were collected through interviews with pregnant women from Atlantic Canada. van Manen’s method of phenomenology was utilized. The data analysis revealed four patterns or major themes: being caught off guard; losing your bearings; hanging on for dear life; and hoping for health. The participants experienced their gestational weight gain as an unexpected “wild ride” that they could not control. The findings highlight the need for health care professionals to provide pregnant women with more support concerning gestational weight gain.
An Analysis of the Effectiveness of Sanctions as a Law Enforcement Tool in International Law: A Case Study of Zimbabwe from 2001 to 2013  [PDF]

Abstract: The focus of this research is analysing the effectiveness of sanctions as a law enforcement tool in international law, a case study of Zimbabwe from 2001 to 2013, to analyse the extent to which sanctions are effective in compelling the behaviour of the targeted ZANU PF elite. The conclusion drawn from this research was that sanctions were not effective in compelling the behaviour of the targets as they strengthened their undemocratic practises and human rights violations. Moreover, the lack of a comprehensive nature of sanctions led the targeted circumventing the restrictions, as there was room for other alternative options. In addition, sanctions ended up hurting the innocent civilians, thereby violating international law.
Using Spatial Econometrics to Measure Ozone Pollution Externalities  [PDF]
C.-Y. Cynthia Lin
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.329130
Abstract: This paper summarizes my previous work in Lin (2010), in which I use spatial econometrics to analyze air pollution externalities. In Lin (2010), state-by-state source-receptor transfer coefficients that can be used as a basis for a location- differentiated permit system are estimated. Results affirm the importance of regional transport in determining local ozone air quality, although owing to non-monotonicities in ozone production the externality is not always negative. Because the origin of emissions matters, results also reject a non-spatially differentiated NOx cap and trade program as an appropriate mechanism for reducing ozone smog.
California’s Agriculture-Related Local Air Pollution Policy  [PDF]

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.48A1004

Air pollution is a critical environmental issue for California, which has some of the nation’s most polluted air basins and also the nation’s most stringent set of state and local air quality standards. This paper reviews my previous work in Lin (2011), in which I examine the effects of agriculture-related local regulations in California on air quality, as measured by the number of exceedances of the CO and NO2 standards, by exploiting the natural variation in policy among the different air districts in California. Agricultural burning policies and penalty fees reduce the pollution from CO. Other policies such as the prohibition on visible emission, fugitive dust, particulate matter, nitrogen and the reduction of animal matter are correlated with higher levels of CO. Regulations on orchard and citrus heaters have no significant effect on the number of exceedances of the CO and NO2 standards.

Tiempo y destino: la fragilidad del bien en Los olvidados
Pech, Cynthia;
Andamios , 2005,
Abstract: the idea of human excellence as inherent of everybody invites us to some ethical questions, when the concept of goodness, a basic element of excellence, turns out to be vulnerable by external influences. this article explore this situation in the film los olvidados (1950) by luis bu?uel, inviting to think about the fragility of goodness in its historical context, and discusses the contradictions in the political discourse of former president miguel aleman: general welfare in contrast with poverty of mayor urban sectors.
