Geogenic Imprint on Groundwater and Its Quality in Parts of the Mamfe Basin, Manyu Division, Cameroon  [PDF]
Richard Ayuk II Akoachere, Thomson Areapkoh Eyong, Sonia Ebot Egbe, Regina Engome Wotany, Michael Obiekwe Nwude, Omagbemi Omoloju Yaya
Journal of Geoscience and Environment Protection (GEP) , 2019, DOI: 10.4236/gep.2019.75016
Abstract:
Groundwater studies in parts of the Mamfe basin are sparse and the Mamfe area has the highest population density in the Mamfe basin. An in-depth study of groundwater rock interaction and groundwater quality is of vital importance. This same part of the basin is the economic centre and as such development of businesses in this area requires knowledge of the groundwater quality. Therefore, this study was undertaken to determine the input of the rock formations on the groundwater solute chemistry and groundwater domestic-agro-industrial quality using hydrogeochemical tools and physicochemical parameters: Ionic ratios, Gibbs diagrams, Piper diagrams, Durov diagrams and water quality indices. From physicochemical parameters, in the rainy season, pH ranged from, 4.3 - 8.6; EC, 3 - 1348 μS/cm; Temperature, 24.4 - 30.1

Richard Ayuk Akoachere, Edwin Ngwene Etone, Roy Lyonga Mbua, Marcelle Pami Ngassam, Simon Ngomba Longonje, Pius Mbu Oben, Regina Wotany Engome
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105327
Abstract:
The South Eastern Piedmont Region of Mount Cameroon is getting in-creasingly populated. Groundwater is the main resource for drinking in this area; hence, the quantification of trace metals, suitability and quality of the groundwater resources for drinking, domestic and agro-industrial uses is of public and scientific concern. In this study, 10 samples were collected from 10 sites in September 2017. Field measurement of physicochemical parameters and investigation of the levels of trace metal content in groundwater was determined using Inductively Coupled Plasma Mass Spectroscopy ICP-MS. R-mode statistical analysis has been done and traces metals elements correlated with the physicochemical parameters and cluster analysis PCA carried out. The paper also highlights and determines the average daily dose ADD, the carcinogenic risks CR and the non-carcinogenic risk hazard quotient HQ which yields the hazard indices HI. The general trend of mean trace metal concentration in the sampled groundwater was in the order of: Zn > Fe > Al > V > Mn > Cu > Cr > Ni > Pb > As > Co > Cd > Sb. All the groundwater risk indices; ADD, CR, HQ and HI were less than 1 in categories of insignificant health risk. The severity of metal toxicity is governed by several factors, such as dose, nutrition, age, and even life style. Therefore, this low trend might not guarantee the complete absence of human health risk. Generally, from risk assessment on trace metals using risk indices, the analyzed water samples might not be at an alarming health risk. However, due to an increasing level of environmental pollution that might be imposed by increasing human activity in this region, water sources might become a potential sink of contaminants; this is significant reason that makes constant monitoring, implementation and treatment of groundwater for drinking purposes obligatory.

Regina Juchun Chu
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.53022
Abstract:

The purpose of this is to investigate how adult female learners constitute their perceptions of self and learning behavior in an internet learning environmentweblog. Based on previous qualitative research method and literature review, this study intended to develop and validate a feminist adult learning strategy scale (FALSS) to understand the women’s learning strategy by applying weblogs. 417 valid data from the participants in two studies (exploratory and confirmatory factor analysis) were analyzed for the purpose. The results of these studies supported a 15-item, 4-factor FALSS: Empowerment Attempt, Sharing Expe- riences, Participatory Learning, and Critical Thinking and Open-Mindedness.

Gender Differences in Perceived Equality and Personal Knowledge System Development on Personal Learning Network  [PDF]
Regina Juchun Chu
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.212008
Abstract: The purpose of this research is to investigate how personal learning network (PLN) facilitates individuals to build up their own epistemologies of the interpretation for their knowledge system. Based on three interviews and literature reviews, this study intends to develop and validate a personal epistemology development scale (PEDS) on PLNs to understand learner knowledge constructions. 561 valid data from the participants in two studies (exploratory and confirmatory factor analysis) were analyzed for the research purpose. The results of these studies supported an 18-item, 4-factor PEDS: description, analysis, vision, and strategy. The results also reveal that equality significantly influences the process of theory development especially for the stage of vision. The result moreover shows gender differences existing in the perception of equality on PLN environment, in the description and in the vision stages.
Forces in Struggle in the Country and the City Today in Brazil: Beyond a Dualistic Understanding  [PDF]
Célia Regina Vendramini
Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.31006
Abstract: Is it still possible to distinguish the line that separates the country and the city? How do rural and urban workers produce their life today? What are the characteristics that distinguish or approximate them? What movements of resistance have been observed? These questions guide our reflections about the relationship between urban and rural space. Based on a study in the urban pe-riphery and in encampments and settlements of the Landless Rural Workers Movements in Brazil, we seek to understand alternative forms of occupation of space today.
Presentation of a Validated Checklist as a Tool for Assessing, Preventing and Managing Food Waste in Foodservices  [PDF]
Tania Regina Kinasz, Regina Baptista Reis, Tania Beninga Morais
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.611102
Abstract: More researches are needed to identify the relevant factors influencing the generation of food waste and devise preventive strategies. The objective of this study is to develop a checklist to assess the good management practices that have a positive impact on eliminating or minimizing food waste in food service units. A theoretical list of relevant factors impacting the generation of food waste during meal production is developed, taking into account administrative planning, receipt and storage of foods, and the preparation and distribution of meals by food service units. For each factor, several administrative and/or technical actions are identified. To validate the content, this list is submitted to a ten-member expert panel for a final evaluation. The factor (and its respective actions) is considered relevant if 80% of the expert panel members agree on its relevance. All actions employ a dichotomous response of Yes/No. Affirmative responses are expected because these actions are considered to be good management practices that have a positive impact on eliminating or minimizing food waste. Following the panel approval process, a checklist of 12 factors and 102 actions is detailed. The conceptual structure of the checklist for food waste management presented in this study enables a comprehensive understanding of the factors that impact food waste, providing a theoretical basis for future research into the relative importance of the relevant factors and actions identified in this study.
Use of Male Condoms among Adolescents with Free Access at Emergency Contraception—Study among Students from the Public Education System of the Sao Paulo, Brazil  [PDF]
Regina Figueiredo, Neuber Jose Segri
World Journal of AIDS (WJA) , 2014, DOI: 10.4236/wja.2014.42023
Abstract:

The research conducted in public schools in Sao Paulo city, Brazil, studied the awareness and use of emergency contraception (EC) and its possible implications on the condoms use. Among the 4929 students, 55.6% had already had sex, 19.5% had got pregnant and 7.3% had had abortions. Condoms were used by 88.6% and were options for those who did not have a steady relationship. The EC was used by 30.3% after a faulty condom usage, and by the older ones, with a steady partner. It is needed to be given contraceptive alternatives to reduce the risk and provide access to other contraceptives.

Márcia Regina Castro Barroso
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.26057
Abstract: This text is a small adaptation of our Master-degree’s dissertation, which had telework performed in Brazilian homes as its main goal. The research as a whole focused on both sociological and legal analyses of the aspects of telework, regarding flexible work schedules, legislation on distance work, hierarchical relationships, space and time organization of work utilizing telematic means, as well as perceptions of the actors involved with this activity. In this paper, the legal aspects of telework in Brazil will be emphasized.
Sex Education in the Eyes of Brazilian Public School Teachers  [PDF]
Denise Regina Quaresma da Silva
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.515160
Abstract:

This article presents the results of a research about the implementation of sex education in the public schools of Novo Hamburgo, Rio Grande do Sul, Brazil. Quantitative and qualitative methods were used and semi-structured interviews were conducted with 124 teachers from 56 public schools. The Discourse of the Collective Subject method was applied to analyse the interviews. The results show that sex education is not a crosscutting theme in schools, and that it is mostly dominated by the biomedical discourse. This means that non-heterosexual practices and identities are neglected and that representations of gender and sexuality that reproduce and legitimate gender disparity are accentuated.

Transitions in Fertility for Brazilian Women: An Analysis of Impact Factors
Regina Madalozzo
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0040756
Abstract: The labor participation of Brazilian women has increased during the last few decades. According to the World Bank, the percentage of Brazilian women participating in the labor market rose from 20% in the early 1970s to 65% (for women between 16 and 64 years of age) in 2009. The fertility profile has also changed, the fertility rate has decreased from 6.2 in 1960 to 1.9 in 2009, below the replacement rate, according to the World Bank. This paper will present Brazilian fertility trends during the previous (20th) and present (21st) centuries and, emphasize the importance of individual profiles for fertility decisions. This work uses Brazilian data from PNAD (Pesquisa Nacional de Amostra por Domicilios) to understand the cause of this relationship and to predict the consequences of these choices on women’s economic development.
