A conceptual framework for understanding contemporary child slavery

This thesis developed a conceptual framework aimed at enhancing our understanding of contemporary child slavery. A new variety of slavery exists today, the result of forms of forced servitude that existed alongside slavery many centuries ago. This is tantamount to slavery. There is, however, a critical lack of awareness about important aspects of the reality of this new child slavery. The framework and definitions of slavery in usage today, though interesting and sufficient to cover historical situations, are unable to adequately describe the conditions of the child slavery. Using existing literature and research, this thesis conceptualized children's labor in a manner that allows a clearer perception of the exploitation of their labor within and beyond the household. Explanatory factors such as culture, the age of victims, the number of hours worked and the ability or not of the victim to volunteer or withdraw their participation in the specific activities were employed to determine if particular situations should be considered as child slavery, repressive child labor or merely as child work. Important distinctions were made between the use of children's mental and physical energy in defined activities. ^

The Allelic Abundance of Afghanistan, a Pool for West and South Eurasian Genes and a Blockade against Eastern Admixture

In this study, I divided samples from individuals within Afghanistan based upon geography (i.e., north versus south). I determined allelic frequencies and other statistical parameters for 15 STR loci (i.e., D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, Dl3S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA). I conducted pairwise comparisons with 19 neighboring Eurasian populations to assign Gstatistics and p-values. Categorizing the populations into five groups (i.e., Central Asia, East Asia, South Asia, the Middle East, and the Caucasus/Anatolia), I derived values for intra-population, inter-population, and total variance. Admixture analyses determined the highest allelic contributions to be from the Caucasus/ Anatolia, while negligible contributions were made by Central Asia and East Asia. A Correspondence Analysis revealed clustering of both northern and southern Afghanistan with Georgia, Turkey, northern Iran, and southern Iran of the Caucasus/ Anatolia and the Middle East. A Neighbor-Joining phylogenetic tree was constructed to generate bootstrap values over 1, 000 reiterations.

Use of child safety seats among Mexican parents in a small south Dade community

The purpose of this study was to determine the use and misuse of child safety seats among Mexican parents. Data were collected via personal interview and by use of the SAFE KIDS BUCKLE UP Child Safety Seat Checklist Form. This study used a descriptive comparative design. The convenience sample consisted of 63 Mexican mothers with at least one child under the age of four (index child). The findings showed that Mexican parents tend to misuse or not use child safety seats. Most parents were not aware of the misuse, and receiving prior information on the use of child safety seats had no bearing on its correct use. Factors influencing nonuse include lack of finances, driving short distances, leaving child safety seat at home, and being unaware of the Florida child restraint law. Findings of this study have implications for how nurses need to educate mothers on car safety and help reduce childhood injuries.

An evaluation of child welfare inservice training: The relative effectiveness of substance abuse content in improving worker knowledge and attitudes

Given the seriousness of substance abuse as a child welfare problem, the purpose of this study was to examine the relative effectiveness of an inservice training curriculum for child welfare workers. The training was designed to improve worker knowledge and attitudes in working with substance abusing families. Seventy (70) child welfare workers from public and private agencies in two south Florida counties participated in a pretest/posttest control group design that also trained and retested the control group. The literature review supports that the general preparedness of child welfare workers for the issues presented by substance abusing families is in question. Confounding this problem is a lack of understanding of substance abuse dynamics, worker biases, and predispositions. The two research hypotheses focused on whether inservice training could increase worker knowledge and improve worker attitudes in working with this population. Training delivery was in the form of a five-day inservice focusing on an array of substance abuse knowledge and attitudinal topics. Separate knowledge and attitude instruments were developed for the research and were administered, before and after training, to a purposive sample of participants that were randomly assigned to the experimental and control groups. The data analysis supported the research hypotheses but raised a question. Specifically, the experimental group demonstrated significant improvement in posttest scores on both instruments after receiving the training; whereas the control group, with training withheld, also demonstrated a significant improvement at posttest, but only on the knowledge instrument. Although the question was unanswered, when examined at a more critical significance level, only the experimental group remained significant. The hypotheses were reconfirmed when, after training and retesting, the control group also displayed significant improvement on both instruments. The findings support the conclusion that this substance abuse inservice was effective in improving worker knowledge and attitudes regarding working with substance abusing families. As an implication for social work practice, it suggests that similar inservice training can be a viable training resource when formal substance abuse training is unavailable. Additional research is suggested regarding to what degree increased substance abuse knowledge and improved worker attitudes correlate with improved practice.

Pollination and breeding of jackfruit ({\it Artocarpus heterophyllus\/} Lam.) in South Florida

Jackfruit (Artocarpus heterophyllus Lam.) is a multi-purpose fruit tree, native to tropical Asia. It was introduced to South Florida in the early 1900s but has had little commercial importance. In recent years, there has been an increased interest in jackfruit as a commercial crop in South Florida, but there has been little scientific investigation conducted. The pollination mechanism was not clearly understood. This study focused on jackfruit breeding using 'Dang Rasimi' and 'Cheena' cultivars. Controlled hand-pollinations revealed that both cultivars were not apomictic. Both cultivars set fruit with self-pollination, but seed set and many fruit characters such as size, flesh percentage and edible percentage were greatly enhanced with cross-pollination. I conclude that jackfruit are outbreeding plants. Tests for pollen dispersal by wind were inconclusive. A variety of insects were collected, but few had a role in pollination. My results suggest that jackfruit are likely to have insect-assisted wind pollination in South Florida. ^
