Visible Body Modification (VBM): Operationalizing Grooming Standards

The purpose of this study was to build on a previous one that focused on the effect of visible body modification (WM) on employment. In this study, samples from actual employee manuals used in the hospitality industry were collected and analyzed, specifically looking at policies regarding visible tattoos and body piercings. Examples from those employee manuals are presented, along with suggestions for operators looking to change or clarify their grooming standards.

A developmental education program model for high -risk minority baccalaureate nursing students

The purpose of this study was to define and describe a Developmental Education Program Model for high-risk minority baccalaureate nursing students based upon perceived needs determined by nursing students and nursing faculty. The research examined differences between Black and Non-Black nursing students in level of importance of concerns and issues related to academic, financial, psycho-social and personal areas of student life; faculty perceptions of the differences between Black and Non-Black nursing students in the level of importance of concerns and issues related to academic, financial, psycho-social and personal areas of student life; and the difference between Black and Non-Black nursing faculty perceptions of level of importance of issues and concerns of academic, financial, psycho-social, and personal areas for Black nursing students. In this study two data collection methods were used, questionnaire and interview. The questionnaire was completed by all students and faculty. Black baccalaureate nursing students and nursing faculty were interviewed. The most significant differences were seen in the category of Personal Issues. Student identified concerns and issues related to both academic and health problems. Faculty identified the greatest differences in Academic Issues. The framework for the model which evolved out of the data uses needs from: (1) a whole person perspective (outcome oriented needs); (2) a programmatic perspective (input oriented needs); and (3) learning domain perspective (process oriented needs). ^

The use of the Dade County student assistance profile in the identification of at -risk students at a minority senior high school

Current high school completion rates in Dade County and across the nation are considered to be unacceptable. This has led to the development of student assistance profiles to aid in the early identification of students considered to be at risk to allow for some form of intervention. The purpose of this research was to examine the current Dade County Public Schools profile as applied to one specific high school in which most of the students are Hispanic (mostly of Mexican descent) and Black (African-Americans, as well as recent Haitian immigrants). Additionally, the effectiveness of the alternative intervention program provided at this high school--a school within a school--were evaluated. School records of the 1992 in-coming ninth grade class became the initial data base. The individual student records of this cohort were then examined over a four-year period until their expected date or graduation. The DCPS profile used to identify potential dropouts from this group was evaluated, using chi-square and multivariate analysis, to determine its overall effectiveness, as well as the effectiveness of the individual indicators which comprise the profile. The Student Assistance Profile was found to an effective predictor, but it over-identified students from this cohort, particularly minorities, to the extent that it became largely ineffective, especially considering the limited resources available for intervention. The intervention program was found to be ineffective in reducing the dropout rate. Further analysis of the individual indicators used in the DCPS profile as they applied to this school population resulted in the development of an improved profile. By reducing the number of indicators to those found to be most highly associated with failure to graduate--academic performance and absences--a simpler student assistance profile was developed which appears to be better suited to high schools with similar demographics and budget restraints. ^

A study of the perceived effectiveness of existing recruitment and general institution -wide practices used to enhance women and minority full -time faculty representation at Florida's public universities

As a federal contractor, the State University System of Florida (SUSF) has instituted a wide range of affirmative action practices to hire and promote women and minorities. Should affirmative action be abolished, universities valuing a diverse faculty will have to rely on voluntary practices to attract members of these groups. I explored the present use and perceived effectiveness of recruitment and institution-wide practices used to promote a diverse workforce and identified those practices considered very effective by informed respondents at the nine participating universities. ^ Two questionnaires were used for data collection. Selected recruitment and general institution-wide best practices found in previous studies were used as benchmarks for comparison with existing practices. The questionnaires also included an open-ended question to identify indigenous practices. A follow-up semi-structured interview was conducted to gather information regarding the background of identified practices. ^ Two overall themes emerged from the study. The first was the perception among respondents that women have made substantial gains in faculty representation. This perception is substantiated by actual percentage of women tenure-earning faculty. The second theme was that many of the practices considered very effective are affirmative action-driven, providing women and minorities considerations not afforded White males. These practices, because they single out members of one group over another based on gender and race/ethnicity may become illegal should affirmative action mandates be abolished. ^ Analysis of the data revealed that universities with the highest percentage of practices considered effective and universities located in the most urban areas of the state were the universities with the highest percentage of minority tenure-earning faculty. There appears to be no similar relationship between universities in urban areas and those with the highest percentage of practices considered effective and women tenure-earning faculty representation. The most frequently identified recruitment practice was the development of a receptive institutional image for women and minorities. The most frequently identified practice in promoting a receptive institutional climate was the use of conflict resolution processes and grievance procedures. Five themes also emerged from the 22 barriers in recruiting women and minority full-time faculty identified by the respondents. The most commonly identified barriers were related to a lack of financial resources to support effective practices. ^

Treatment attrition among racial /ethnic minority adolescents participating in a brief motivational intervention for substance use problems: The influence of individual, social, cultural, and treatment factors

The present study has the primary aim of examining the predictors of treatment attrition among racial/ethnic minority adolescents with substance use problems. This study explores the potential differential influence of specific individual, social, cultural, and treatment factors on treatment attrition within three racial/ethnic subgroups of adolescents. Participants: A unique feature of the study is the use of a racial/ethnic minority sample (N=453), [U.S.-born Hispanics (n = 262), Foreign-born Hispanics (n = 117), and African-Americans (n = 74)]. Multivariate logit analyses were used to examine the influence of specific factors on treatment attrition among the full sample of adolescents, as well as within each racial/ethnic subgroup. Consistent with expectations, multivariate logit analyses reveal that, the specific factors associated with attrition varied across the three racial/ethnic subgroups. Having parents with problem substance use, being on the waitlist, and being court mandated to treatment emerged as predictors of attrition among the US-born Hispanics, while only Conduct Disorder was significantly associated with greater attrition among foreign-born Hispanics. Finally, among African-Americans, parental crack/cocaine use, parental abstinence from alcohol, and being on the waitlist were predictive of attrition. Multiple factors were associated with treatment attrition among racial/ethnic minority adolescents with specific factors differentially predicting attrition within each racial/ethnic subgroup. African-American youth were more than twice as likely as their Hispanic counterparts to leave treatment prematurely. It is critically important to understand the predictors of attrition among racial/ethnic minority youth in order to better meet the needs of youth most at risk of dropping out. ^

Paper Presentation

Can minority language proficiency pay: a study on the return on English-Spanish fluent bilingualism in South Florida

This thesis studies the economic return for fluent-bilingualism in South Florida among native-born whites using IPUMS (Integrated Public Use Microdata Series) data for Miami-Dade County (1990). Previous mainstream-oriented theories focus on the benefit in English acquisition for immigrants and their descendants, either denying or ignoring the possible benefit of minority language retention in addition to English acquisition. An alternative literature, on the other hand, suggests that minority language retention can be beneficial in at least three areas: 1) enhancing cognitive ability; 2) accessing community-level social capital; and 3) serving as human capital. This study assesses economic returns in employment and earnings, using logistic and OLS (Ordinary Least Square) regression respectively. The results, countering the mainstream-oriented theories, suggest that fluent bilingualism does have economic consequences. Rather than fully supporting the positive effects thesis, the patterns shown are much more complicated, contingent on an individual's ethnic membership and educational level. Theoretical and substantive implications are discussed and suggestions for future research are made.

Valutazione delle prestazioni di reti ad accesso multiplo basate su visible light communication

Nella società odierna, le telecomunicazioni costituiscono un’esigenza fondamentale della vita quotidiana. Difatti, il mercato della ICT (Information and Communications Technology) è in costante espansione, e viene accompagnato da un rapido sviluppo di nuove tecnologie. In particolare, si assiste a un sempre più rilevante ruolo svolto dalle comunicazioni ottiche, ovvero sfruttanti la luce: in questo contesto, il quale comprende diversi rami ingegneristici, si stanno progressivamente affermando nuove forme di comunicazione basate sulla luce visibile, la cosiddetta Visible Light Communication (VLC). Con questa Tesi ci si propone di implementare con Simulink e stateflow di Matlab il livello MAC (Medium Access Control), basato sullo standard IEEE 802.15.7 per le VLC e valutarne le prestazioni. Prescinde da questa Tesi la parte di implementazione su scheda stessa che è lasciata per sviluppi futuri. Nel capitolo uno si introducono le VLC e si discutono i principali scenari attuali dove possono diffondersi. Nel capitolo 2, si mostrano le principali linee guida afferenti agli standard che sono risultate necessarie per sviluppare lo strato MAC. Nei capitoli 3 e 4 si mostra come il layer sviluppato possa essere utilizzato in due principali situazioni: nel capitolo 3 è descritta la realizzazione di una comunicazione punto-punto, ovvero con un trasmettitore e un ricevitore; nel capitolo 4 è descritta l’implementazione di una rete di nodi, ambito in cui il livello MAC risulta indispensabile. Per ognuna delle situazioni si illustrano scelte e caratteristiche dei sistemi simulati e i risultati ottenuti, cercando di coprire diverse eventualità che intercorrono, più in generale, nella gestione e implementazione di sistemi di telecomunicazione wireless.

High-resolution spatial-response measurements of optical nano-antennas in the visible

A few years ago, some of the authors of the paper demonstrated the resonance of optical antennas in the visible frequencies. The results of that paper were obtained using experimental techniques that were primarily developed for the measurement of antenna-coupled detectors in the infrared. In the present paper, we show the results of spatial-response mapping obtained by using a dedicated measurement station for the characterization of optical antennas in the visible. At the same time, the bottleneck in the spatial responsivity calculation represented by the beam characterization has been approached from a different perspective. The proposed technique uses a collection of knife edge measurements in order to avoid the use of any model of the laser beam irradiance. By taking all this into account we present the spatial responsivity of optical antennas measured with high spatial resolution in the visible.

Emergence of additional visible range photoluminescence due to aggregation of cyanine dye:astraphloxin on carbon nanotubes dispersed with anionic surfactant

Self-organization of organic molecules with carbon nanomaterials leads to formation of functionalized molecular nano-complexes with advanced features. We present a study of physical and chemical properties of carbon nanotube-surfactant-indocarbocyanine dye (astraphloxin) in water focusing on aggregation of the dye and resonant energy transfer from the dye to the nanotubes. Self-assembly of astraphloxin is evidenced in absorbance and photoluminescence depending dramatically on the concentrations of both the dye and surfactant in the mixtures. We observed an appearance of new photoluminescence peaks in visible range from the dye aggregates. The aggregates characterized with red shifted photoluminescence peaks at 595, 635 and 675 nm are formed mainly due to the presence of surfactant at the premicellar concentration. The energy transfer from the dye to the nanotubes amplifying near-infrared photoluminescence from the nanotubes is not affected by the aggregation of astraphloxin molecules providing important knowledge for further development of advanced molecular nano-complexes. The aggregation with the turned-on peaks and the energy transfer with amplified photoluminescence create powerful tools of visualization and/or detection of the nanotubes in visible and near-infrared spectral range, respectively, boosting its possible applications in sensors, energy generation/storage, and healthcare.

Epitaxial growth of visible to infra-red transparent conducting In2O3 nanodot dispersions and reversible charge storage as a Li-ion battery anode

Unique bimodal distributions of single crystal epitaxially grown In2O3 nanodots on silicon are shown to have excellent IR transparency greater than 87% at IR wavelengths up to 4 μm without sacrificing transparency in the visible region. These broadband antireflective nanodot dispersions are grown using a two-step metal deposition and oxidation by molecular beam epitaxy, and backscattered diffraction confirms a dominant (111) surface orientation. We detail the growth of a bimodal size distribution that facilitates good surface coverage (80%) while allowing a significant reduction in In2O3 refractive index. This unique dispersion offers excellent surface coverage and three-dimensional volumetric expansion compared to a thin film, and a step reduction in refractive index compared to bulk active materials or randomly porous composites, to more closely match the refractive index of an electrolyte, improving transparency. The (111) surface orientation of the nanodots, when fully ripened, allows minimum lattice mismatch strain between the In2O3 and the Si surface. This helps to circumvent potential interfacial weakening caused by volume contraction due to electrochemical reduction to lithium, or expansion during lithiation. Cycling under potentiodynamic conditions shows that the transparent anode of nanodots reversibly alloys lithium with good Coulombic efficiency, buffered by co-insertion into the silicon substrate. These properties could potentially lead to further development of similarly controlled dispersions of a range of other active materials to give transparent battery electrodes or materials capable of non-destructive in situ spectroscopic characterization during charging and discharging.
