Academic achievement orientation of West Indian American parents and adolescents

Literature addressing academic achievement orientation of Black adolescents in the United States often depicts poor school related attitudes and adaptation patterns, low academic achievement, and deficient family backgrounds. However, some researchers maintained that certain Black immigrant groups possessed positive academic achievement orientations and exemplary academic achievements (Ogbu, 1991; Gibson, 1991; Vernez, & Abrahamse, 1996). In this study, I attempted to combine qualitative data from multiple sources (surveys, interviews, observations, literature, and document analysis), using standard case study methodology and the constant comparative method of analysis to understand the relationship that existed between the academic achievement orientation of a select group of West Indian American parents and adolescents in Broward County, Florida. The sub-sample of 11 families, comprising 15 adolescents and 13 parents, was selected through maximum variation sampling from a pool of 23 families. The findings were presented as a single composite case study. The participants possessed specific, longstanding educational and career goals for the children. The parents were deeply involved and were knowledgeable of their children's schools and academic progress. While mothers were the parents most actively involved in the schools, fathers were strong authoritative figures. Families evidenced a strong moral religious base with set rules of behavior, firm parenting practices, and established chains of authority. Family members emphasized education over material things; reading over audiovisual or social activities; family cohesion over individual wishes; and academics over extracurricular activities. The parents' strong positive academic achievement orientation was communicated to the children and reinforced by relatives, family friends, and others. In turn, the adolescents possessed positive school-related attitudes and attributional styles. While they admitted their parents were somewhat strict, they voluntarily complied with the rules and were highly motivated to succeed because they believed their parents deeply cared for them and that education leads to success and upward mobility. Each adolescent was pursuing an academic track and planning for college and specific profession. The findings support Ogbu's cultural ecological model (1991). I recommend these findings to teachers, counselors, administrators, parents, and others working with West Indian American families. ^

A phenomenological exploration of how West Indian professionals in South Florida perceive their career construction

This phenomenological study explored how West Indian professionals in South Florida perceive their career construction. The study used Savickas’s (2005) theory of career construction as its theoretical framework. Semi-structured interviews were conducted, transcribed, and analyzed for 15 West Indian professionals, who self-identified as West Indians and met all the criteria for this study. Interview data were analyzed using inductive, deductive, and comparative analyses. Five themes emerged from the inductive analysis of the data: (a) vocational influences, (b) adjustment challenges, (c) employment patterns, (d) career mobility patterns, and (d) career success perceptions. The theory of career construction guided the deductive analysis. The deductive analysis revealed that both extrinsic and intrinsic influences were equally influential in shaping the participants’ vocational personalities. The deductive analysis also revealed that the participants used three of the career adaptive dimensions: career concern, control, and confidence. Career concern manifested as planning for the future through educational attainment and performing meaningful work. Career control manifested as continuous learning and maintaining secondary careers. Career confidence manifested as self-efficacy expectations, beliefs about one’s ability to perform a behavior that produces desired outcomes. The participants’ life themes or challenges included navigating their identity, starting over, and adjusting to their environment. The comparative analysis revealed that all five themes from the inductive analysis were evident in each of the three tenets of Savickas’s (2005) career construction theory (i.e., vocational personality, career adaptability, and life themes). Career compromises emerged as coping behavior to facilitate the participants’ social and occupational integration. The findings of this study imply that the participants constructed their sense of self in relation to those around them and that their vocational behaviors tend to mobilize and reinforce a mixture of personality and ability. The findings also imply that the participants’ decision-making style and habitual pattern of decision making, may be embedded in their culturally norms, producing a specific cognitive style. Finally, the findings imply that the participants’ career adaptive dimensions were grounded in their attitudes, beliefs, and competencies and overall self-concept. Recommendations for further research are given.

Phylogenetics, conservation, and historical biogeography of the West Indian members of the Adelieae (Euphorbiaceae)

The Caribbean Island Biodiversity Hotspot is the largest insular system of the New World and a priority for biodiversity conservation worldwide. The tribe Adeliae (Euphorbiaceae) has over 35 species endemic to this hotspot, representing one of the most extraordinary cases of speciation in the West Indies, involving taxa from Cuba, Hispaniola, Jamaica, and the Bahamas. These species form a monophyletic group and traditionally have been accommodated in two endemic genera: Lasiocroton and Leucocroton. A study based on: (1) scanning electron microscopy of pollen and trichomes, (2) macromorphology, and (3) molecular data, was conducted to reveal generic relationships within this group. Phylogenies were based on parsimony and Bayesian analyses of nucleotide sequences of the ITS regions of the nuclear ribosomal DNA and the non-coding chloroplast DNA spacers psbM-trnD and ycf6-pcbM. One species, Lasiocroton trelawniensis, was transferred from the tribe into the genus Bernardia. Of the remaining species, three major monophyletic assemblages were revealed, one was restricted to limestone ares of Hispaniola and was sister to a clade with two monophyletic genera, Lasiocroton and Leucocroton. Morphological, biogeographical, and ecological data provided additional support for each of these three monophyletic assemblages. The Hispaniolan taxa were accommodated in a new genus with four species: Garciadelia. Leucocroton includes the nickel hyperaccumulating species from serpentine soils of Cuba, while the rest of the species were placed in Lasiocroton, a genus restricted to limestone areas. The geographic history of the islands as well as the phylogenetic placement of the Leucocroton-alliance, allows the research to include the historical biogeography of the alliance across the islands of the Caribbean based on a dispersal-vicariance analysis. The alliance arose on Eastern Cuba and Hispaniola, with Lasiocroton and Leucocroton diverging on Eastern Cuba according to soil type. Within Leucocroton, the analysis shows two migrations across the serpentine soils of Cuba. Additional morphological, ecological, and phylogenetic analyses support four new species in Cuba (Lasiocroton gutierrezii) and Hispaniola ( Garciadelia abbottii, G. castilloae, and G. mejiae). ^

Immunocytes of the Atlantic bottlenose dolphin (Tursiops truncatus) and West Indian manatee (Trichechus manatus latirostris): Morphologic characterizations and correlations between healthy and disease states under free-ranging and captive conditions

Interest in the health of marine mammals has increased due, in part, to the attention given to human impact on the marine environment. Recent mass strandings of the Atlantic bottlenose dolphin (Tursiops truncatus) and rising mortalities of the endangered Florida manatee (Trichechus manatus latirostris) have raised questions on the extent to which pollution, infectious disease, "stress," and captivity influence the immune system of these animals. This study has provided the first in-depth characterization of immunocytes in the peripheral blood of dolphins (n = 190) and manatees (n = 56). Immunocyte morphology and baseline values were determined in clinically normal animals under free-ranging, stranded and captive living conditions as well as by age and sex. Additionally, immunocyte population dynamics were characterized in sick animals. This was accomplished with traditional cytochemical techniques and new lymphocyte phenotyping methodology which was validated in this study. Traditional cytochemical techniques demonstrated that blood immunocyte morphology and cell numbers are similar to terrestrial mammals with some notable exceptions. The manatee heterophilic granulocyte is a morphologically unique cell and probably functions similarly to the typical mammalian neutrophil. Eosinophils were rarely found in manatees but were uncommonly high in healthy and sick dolphins. Basophils were not identified. Manatees had higher total lymphocyte numbers compared to dolphins and most terrestrial mammals. Lymphocyte subsets identified in healthy animals included T$\rm\sb{h}$, T$\rm\sb{c/s}$, B and NK cells. Dolphin and manatee T and B cell values were higher than those reported in man and most terrestrial mammals. The manatee has extraordinarily high absolute numbers of circulating T$\rm\sb{h}$ cells which suggests an enhanced immunological response capability. With few exceptions, immunocyte types and absolute numbers were not significantly different between free-ranging, stranded and captive categories or between sex and age categories. The evaluation of immunocyte dynamics in various disease states demonstrated a wide variation in cellular responses which provided new insights into innate, humoral and cell-mediated immunity in these species. Additionally, this study demonstrated that lymphocyte phenotyping has diagnostic significance and could be developed into a potential indicator of immunocompetence in both free-ranging and captive dolphin and manatee populations.

Correlações entre os caracteres físico-químicos de frutos da aceroleira com variáveis meteorológicas

Com objetivo de estimar as associações entre os caracteres físico-químicos do fruto com variáveis meteorológicas, conduziu-se um experimento no pomar da Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal, no período de dezembro/97 a janeiro/99, avaliando-se em cada colheita espontânea de 5 genótipos, valores médios de altura e diâmetro de vinte frutos, teor de vitamina C, ºBRIX, pH, rendimento médio de polpa em três amostras de vinte frutos, massa média de frutos e tempo de colheita em dias. Os dados meteorológicos diários utilizados foram obtidos na Estação Agroclimatológica do Departamento de Ciências Exatas da FCAV/ UNESP. Baseando-se nas maiores correlações entre as médias das temperaturas máxima (TMAX), mínima (TMIN) e média (TME) no período de colheita (1), no período de colheita incluindo-se os três dias antecedentes (2) e no período de colheita incluindo-se os dez dias antecedentes (3), associadas com os caracteres físico-químicos de frutos, elegeu-se TMIN2, como a mais influente entre as estudadas e estimou-se o somatório da precipitação (PR) e horas-luz diárias (HL) do mesmo período. Com as estimativas de precipitação e insolação em horas-luz diárias e TMIN2, obtiveram-se as correlações entre os caracteres físico-químicos de frutos de aceroleiras na média geral e dentro da média de cada genótipo analisado. Concluiu-se que as variáveis meteorológicas TMIN2, PR e HL apresentaram respostas diferenciadas dentro de cada genótipo, influenciando as expressões dos caracteres físico-químicos de seus frutos e que as correlações entre HL e tempo de colheita em dias, entre e dentro de todos os genótipos estudados, foram direta e altamente significativas, de modo que a variável HL condicionou a periodicidade e extensão das colheitas (safras).

Normalização dos níveis séricos de ácido ascórbico por suplementação com suco de acerola (Malpighia glabra L.) ou farmacológica em idosos institucionalizados

INTRODUÇÃO: Este estudo investigou o tempo necessário de suplementação com vitamina C, para a normalização dos níveis séricos em idosos com deficiência dessa vitamina e comparar o efeito da vitamina natural do suco de acerola (Malpighia glabra L.) com o da vitamina na forma de fármaco. MÉTODOS: Foram estudados 37 idosos institucionalizados do município de João Pessoa, Paraíba, Brasil, divididos em 3 grupos: Grupo I - controle, Grupo II - suplementação com o suco de acerola e Grupo III - suplementação com fármaco. A metodologia empregada consistiu na dosagem sérica de ácido ascórbico e na verificação do consumo alimentar por inquérito dietético. Constatou-se um aumento significativo (p<0,05) nas médias dos níveis séricos de ácido ascórbico, após 10 dias (1,27±0,41mg/dL), 20 (1,69±0,45mg/dL) e 30 dias (1,55±0,42mg/dL) de suplementação aos valores iniciais (0,38±0,28mg/dL). No 10º dia de suplementação, os idosos suplementados com suco de acerola apresentaram níveis significativamente mais elevados (1,41±0,43mg/dL) do que aqueles que foram suplementados com comprimidos (1,03±0,25mg/dL). CONCLUSÃO: Considerando-se que, no 20º dia, o efeito da suplementação foi satisfatório para a normalização dos níveis séricos daqueles indivíduos, esse tempo poderia ser utilizado para idosos em geral e, em especial, para aqueles que vivem em instituições destinadas a idosos carentes, sendo o suco de acerola um suplemento indicado por ser um produto natural e de fácil aquisição.

Seleção de genótipos parentais de acerola com base na divergência genética multivariada

Este trabalho teve por objetivo identificar e selecionar genótipos parentais de acerola (Malpighia emarginata L.) adequadas a programas de melhoramento genético. Nove caracteres quantitativos de maior importância agronômica foram usados para determinação da distância genética e formação de grupos similares de acessos. O agrupamento pelo método de Tocher, a partir das distâncias generalizadas de Mahalanobis, possibilitou a divisão de 14 genótipos em três grupos. Com base na divergência genética e no caráter agronômico-chave (teor de vitamina C), destacaram-se como mais promissores os cruzamentos dos genótipos: AM Mole pertencente ao grupo III, com os genótipos PR AM, N° 18, PR 17, PR 16, Eclipse, AM 22 e Dominga, todos pertencentes ao grupo I.
