Neuroplasticity and Positive Psychology in Clinical Practice: A Review for Combined Benefits  [PDF]
Joyce Shaffer
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A164

Research on using positive psychological perspectives to drive brain plasticity in a positive direction is increasingly encouraging and empowering for clinicians and clients. Increased lifespan with neuroplastic gains was found by Diamond in lab rats when they were held and spoken to. Improvements in brain chemistry, architecture and performance associated with lifestyle choices are now being documented in humans with increasing frequency of reports. Positive psychology can strengthen this trend toward increases in wellbeing by using this evolving research for motivation to increase healthy lifestyle choices, for reinforcement of successive approximation toward these goals and for the many gains associated with greater happiness.

Abstract: this research refers the results of a qualitative study which purpose was to describe and understand the teaching practices of six secondary science teachers who have transformed their teaching practice by applying an inquiry approach. the method used was grounded theory applied to the observation of 54 class hours (cr.). this research contributes with descriptive and comprehensive information about characteristics of the observed practices, as well as the conditions that allow them and their consequences. finally, we discuss the implications that this study has on pre-service and in-service secondary science teacher education.
Conflictos de intensidad de uso de la tierra en las estaciones experimentales de la Universidad Central de Venezuela: Análisis espacial con sistemas de información geográfica
Agronomía Tropical , 2005,
Abstract: the universidad central de venezuela has 13 experimental stations (ee) under the administration of the agronomy and veterinary faculties. these ee occupy around 6.500 ha , spread in eight states of the national territory, and they constitute an immense patrimonial value for the university and the society, not only for their economic capital, but also for their potential for production activities, agricultural extension, and educational programs. currently ee activities are executed in a disjointed way, without responding to an integral development and management plan. land use intensity is low and investigation, agricultural extension, and educational activities have diminished. the aim of this work was to locate and quantify intensity land use conflicts in the main six ee, in order to provide basic information for the formulation of development plans that will allow intensifying resources use for environmental, economic and social sustainable development. first of all stations legal boundaries were identified, then, current use and vegetation cover were characterized and their agricultural land capability was evaluated. spatial analysis tools included in the geographical information systems (gis) helped to overlay generated information layers. a crossed classification was carried out, in order to confront land current use with land potential use, determining areas with intensity land use conflicts either for over-use or for sub utilization, as well as those under correct use. areas with legal possession problems were identified. it was determined that 76.91% of the stations land is being sub-utilized, 0.20% is being over-used, and 10.29% of the land is well used. some lots covering about 1% have land tenure problems, and in some cases the whole station have a precarious property regime.

Lilliana Abarca Guerrero Abarca Guerrero
Tecnología en Marcha , 2010,
Abstract: Se decidió analizar cuál es la situación actual en el manejo de los desechos, con el objetivo de determinar la variación en los índices de generación de los desechos domésticos y establecer cuál es la situación con respecto a algunos hospitales privados. La información servirá de insumo para el Proyecto “Estado de la Nación” del 2005, a través del cual se realiza un esfuerzo continuo para informar a la sociedad sobre aspectos relevantes para que, de esta manera, pueda entender su propia realidad y participar en las orientaciones y acciones futuras por realizar, pues la información es fundamental para el funcionamiento de la democracia. Para conocer la realidad se necesitan datos que ayuden en la construcción de indicadores que reflejen la compleja realidad nacional. Con el presente trabajo se presentan algunos indicadores para la generación de desechos domiciliarios correspondientes a algunas municipalidades de zonas urbanas y zonas rurales, así como los obtenidos para hospitales privados, comparados con datos disponibles de algunos hospitales públicos de la Caja Costarricense del Seguro Social.
Why adults and teachers information about sexual behavior and its consequences does not prevent unplanned pregnancies among adolescents in Nairobi, Kenya  [PDF]
Joyce W. Kinaro
Health (Health) , 2013, DOI: 10.4236/health.2013.51003

Context: Despite a high number of unwanted pregnancies in Kenya, contraceptive use among adolescents is very low. Establishing the nature of sexuality discussions is critical to determine perceptions and barriers affecting contraceptive use among adolescents. Methods: The study used systematic random sampling to collect data to examine sexuality information and knowledge that affect perception and barriers on contra-ceptive use among 1119 adolescents aged 15 - 19 years in Nairobi. The survey was conducted using the 2009 Kenya Demographic and Health Survey enumeration areas and projections based on the 1999 population census. Data were collected using structured interviews, focus group discussions (FGDs) and in-depth interviews (IDIs) among adolescents, parents and teachers. Quantitative data were analyzed using Statistical Package for Social Sciences (SPSS) software while qualitative information was analyzed using iT Atlas. Results: Although teachers were identified as a primary source of sexuality information, they were poorly prepared to teach the subject. While the study found negative perceptions on sexuality education, most FGDs and IDIs supported the need for its integration in the school curriculum. Most adolescents who used con- traceptives had perceptions that their parents approved. Source of sexuality information, living arrangement and perceptions on contraceptives for unmarried adolescents were statistically associated with contraceptive use. Conclusion: The study showed that sexuality information from parents and teachers was biased against adolescents using contraceptives. There is need to address attitudes in discussing contraceptive use for adolescents by parents and teachers to enhance positive perceptions and increase contraceptive use by adolescents.

“They Will Wonder What Kind of a Girl I Am”: Adolescent Perceptions towards Contraceptive Use in Nairobi  [PDF]
Joyce W. Kinaro
Advances in Sexual Medicine (ASM) , 2013, DOI: 10.4236/asm.2013.31001

As in other developing countries, contraceptive use among adolescents is low and only one in twenty adolescents is reported to use contraceptives inKenya. Pregnancies early in life expose adolescents to health complications. Establishing perceptions that affect contraception and factors that influence those perceptions is important in developing appropriate programs and policies to increase contraceptive use prevalence among adolescents. We used primary data from a household survey using a systematic random sampling in eight administrative divisions inNairobiCountyin 2010. The study utilized information collected using structured interviews, focus group discussions (FGDs) and in-depth interviews (IDIs). The findings revealed that perceptions on parental approval, adolescent approval, ability to get contraceptives for self, knowledge of how to use contraceptives and sexual partner communication had significant effect on contraception. The narratives showed that parents, teachers and service providers had negative perceptions and discouraged contraception among adolescents thereby influencing use. Parents and teachers had inadequate knowledge and skills to communicate sexuality messages creating potential environment likely to have indirect negative influence on adolescents’ perceptions on contraception.

Analysis of Pupils’ Difficulties in Solving Questions Related to Fractions: The Case of Primary School Leaving Examination in Tanzania  [PDF]
Joyce Lazaro Ndalichako
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.49B014

In this paper, analysis of the performance of candidates in Mathematics in Primary School Leaving Examination was conducted with the aim of highlighting difficulties encountered in solving fraction-related problems. The analysis has indicated that a considerable number of candidates could not perform correct operations related to fractions. They tended to confuse fraction concepts with whole number concepts. For instance, in questions involving addition of fractions, they were treating numerators and denominators as separate entities. Possible reasons for such difficulties in solving questions related to fractions include lack of understanding of appropriate procedures to apply in solving a problem, the complexity of the task, over-generalization of procedures even in situations which are inappropriate. It is recommended that a protocol analysis be conducted in order to gain a deep understanding of the thought process of candidates when attempting questions related to fractions so that teachers may use relevant teaching methods that would facilitate meaningful learning of fractions.

New Griottes of the African Sahel: Intersectionalities and Women’s Narrative Authority in Sanou Bernadette Dao’s La Dernière èpouse & A?cha Fofona’s Mariage on Copie  [PDF]
Joyce Hope Scott
Advances in Literary Study (ALS) , 2016, DOI: 10.4236/als.2016.44010
Abstract: African women have played a central role in the development of oral literary traditions of countries of the African Sahel historically, yet very few have actually written works and had them published. Among the few who have recently emerged, some have brought new perspectives on historical and contemporary issues as well as innovative techniques in style and narrative structure. Two novels in particular by contemporary women writers from the African Sahel engage issues of women’s agency and the power of narrative authority to interrogate the structures of intersectionality that impact women’s lives: La Dernière épouse (The Last Wife), by Sanou Bernadette Dao of Burkina Faso, and Mariage on Copie (Images of Marriage), by A?cha Fofana of Mali. These works confront the discursive authority of male fictive texts of the post-colonial experience as their female characters seize la parole (the word) to remap representations of traditional male/female relationships.
Travel as Subversion in 19th Century Black Women’s Narratives  [PDF]
Joyce Hope Scott
Advances in Literary Study (ALS) , 2017, DOI: 10.4236/als.2017.54009
Abstract: Race and gender proved to be two daunting obstacles for African American and Afro-Caribbean women in the 19th century; thus success outside those domains often depended on women’s ability to keep a strong feminist stance. Prescribed female roles and racial prejudice hindered many in their ambitions and endeavors. This paper argues that some 19th century black women’s narratives, however, point to a body of resistance texts in contention with prescribed roles for such women. The textual personas of such narratives transcend the confines of home and racially-configured communities. In fact, the narratives foreground a female agency where personal worth and identities are reconstructed through traveling and working in the global arenas and economies of the 19th century world.
