Nesta pesquisa, em 14 pacientes da Clínica de Prótese Total da Faculdade de Odontologia da Universidade de São Paulo, foi realizada a avaliação da retenção de prótese total bimaxilar em função das características da área basal por três avaliadores clínicos experientes e calibrados. Foram avaliadas as retenções vertical anterior, laterais direita e esquerda e póstero-anterior e as características da área basal: forma, tamanho, altura e tipo do rebordo e a consistência da fibromucosa. Por se tratarem de opiniões, os dados foram transformados em escores e submetidos à análise de variância não paramétrica com o teste KRUSKAL-WALLIS e paramétrica com o teste ANOVA. Concluiu-se que, na maxila, a retenção das próteses totais novas foi influenciada positivamente pelo tipo rebordo paralelo e pela consistência resiliente da fibromucosa, enquanto na mandíbula influenciaram o tamanho médio e a forma oval. As opiniões sobre a retenção e o grau de satisfação entre os avaliadores e os pacientes foram as mesmas.; In this research, a evaluation of the retention of bimaxilar complete denture in function of the characteristics of the basal area by three calibrated experienced clinician was accomplished in 14 patients of the Odontology College of the University of São Paulo.

Os genes eucarióticos, em sua maioria, são divididos em exons e introns, requerendo processamento do RNAm para remover as sequências intrônicas e juntar os exons (splicing). As bordas exon/intron são definidas por sítios de splice que normalmente são reconhecidos com alta fidelidade, gerando os mesmos RNAms processados a cada vez. Apesar desse reconhecimento preciso, tem sido observada a junção de exons de maneiras alternativas (splicing alternativo), foco de muitos estudos recentes devido à sua importância em vários processos biológicos. Este processamento alternativo do RNAm pode ser principalmente de três tipos: exclusão de exon, no qual um exon pode ser incluído ou não no RNAm maduro; uso alternativo de sítios de splice, resultando em exons mais longos ou mais curtos e retenção de intron, o tipo menos estudado, no qual uma sequência intrônica é mantida no RNAm maduro. Um dos aspectos cruciais no entendimento de splicing alternativo é conhecer os mecanismos que levam à geração de diferentes transcritos. Coerente com a importância dos sítios de splice no splicing de RNAms, a retenção de intron parece ser causada por falha no reconhecimento daqueles que são sub-ótimos. Como os sítios de splice são reconhecidos aos pares ao se estabelecer uma ponte através de exons ou introns...

A estrutura do solo está relacionada com o arranjo das partículas, agregados e poros que constituem este meio poroso. As influências estruturais do solo atuam em diversas escalas tanto macroscópicas como microscópicas. Mudanças estruturais em escala microscópica são importantes porque causam alterações no arranjo das partículas do solo e, conseqüentemente, mudanças na distribuição de poros. A qualidade das amostras de solo está diretamente relacionada a sua estrutura, a qual é extremamente importante devido à influência que exerce no desenvolvimento das raízes, fauna do solo, movimento e retenção de água e gases, etc. As alterações que ocorrem na estrutura do solo podem ser induzidas tanto por forças naturais quanto pela ação humana. Ciclos de umedecimento e secamento (U-S) causam grandes modificações na estrutura do solo, especialmente na distribuição do tamanho de poros, a qual reflete a distribuição espacial e temporal da umidade do solo. Conseqüentemente, estes processos podem afetar a retenção e o movimento de água e nutrientes no solo, tendo importantes conseqüências práticas em determinações de armazenamento e potencial mátrico da água no solo, amplamente usados em irrigação. O objetivo principal deste estudo foi aplicar as técnicas de tomografia computadorizada...

As mamites ou mastites, processos inflamatórios da glândula mamária, foram consideradas responsáveis por grandes prejuízos na pecuária leiteira; para a instalação das mamites considerou-se ser necessária a interação de dois fatores etiológicos fundamentais. Os fatores etiológicos predisponentes a instalação de um processo inflamatório da glândula mamária podem ser divididos em: condições ligadas à fisiologia dessa glândula (descida do leite, aumento do volume de leite residual e velocidade de ordenha); condições relacionada à estrutura anatômica do úbere e favorecendo a ocorrência de traumatismos (alterações morfológicas da mama, incluindo os tetos, edema e congestão mamária) e associação a condições predisponentes ligados a enfermidades sistêmicas ou da própria mama (afecções, infestações e infecções). A perfeita descida do leite permite uma adequada ordenha da vaca, restando nestas circunstâncias apenas um pequeno volume de secreção láctea nas cisternas da glândula e no sistema de ductos galactóforos, favorecendo a higidez do órgão. A retenção de maior volume de leite nos ductos e ácinos glandulares foram consideradas por si só indutora de inflamação do tecido epitelial de revestimento interno da mama...

Retention of particulate organic matter was investigated over a range of water discharges in pool and riffle zones of a tropical stream (Itauna Stream, São Paulo, Brazil). A closed-system leaf release and capture method was used to quantify leaf retention in a 50-m reach of the stream. Instantaneous retention rates (k) were calculated by a negative exponentialmodel and specific retention rates (ke) computed for each 1m interval. The mean k was 0.0161 +/- 0.0101 (S.E.) and ranged from 0.005 to 0.036 during the study period. This suggests a low retention of particulate matter. The evidence provided by this study shows that there was a relationship between retention and discharge. At low discharges, greater percentages of leaves were retained in a 3-h period while high discharges resulted in low retention percentages within the studied reach. In the Itauna Stream, no significant difference (p < 0.05) was found between the ke values of pool and riffle zones.

The ultimate purpose of this paper is to present a new analytical formulation to simulate diffusion with retention in a reactive medium under stable thermodynamic conditions. The analysis of diffusion with retention in a continuum medium is developed after the solution of an equivalent problem using a discrete approach. The new law may be interpreted as the reduction of all diffusion processes with retention to a unifying phenomenon that can adequately simulate the retention effect namely a circulatory motion. It is remarkable that the governing equation requires a fourth order differential term as suggested by the discrete approach. The relative fraction of diffusion particles β is introduced as a control parameter in the diffusion-retention law as suggested by the discrete approach. This control parameter is essential to avoid retention isolated from the diffusion process. Two matrices referring to material properties are introduced and related to the real phenomenon through the circulation hypothesis. The governing equation may be highly non-linear even if the material properties are constant, but the retention effect is a function of the concentration level, that is, β is a function of the concentration.

INTRODUCTION: We aimed to investigate the rate of urinary retention after knee arthroplasty, the various factors involved in predicting those at risk for retention and to assess the impact of retention and catheterization on joint sepsis. MATERIALS AND METHODS: A retrospective review was conducted of all available case notes of patients undergoing total knee arthroplasty in a consecutive 2-year period (2000-2002). Adequate data was available for 142 patients. RESULTS: 142 patients underwent total knee arthroplasty. 19 patients were catheterized preoperatively for monitoring urine output. 123 patients were not catheterized. Urinary retention occurred in 19.7% (28/142). The mean day of catheterization for retention was 0.66. The mean duration of catheterization in patients developing retention was 3.58 days and was 3 days in the patients catheterized pre - or perioperatively. Deep joint sepsis occurred in 2.1% (3/142) - only one had been catheterized and that was preoperatively. No case of infection had urinary retention or had a symptomatic urinary tract infection. The only factors predicting those at significant risk of retention following knee arthroplasty was a past medical history of urinary retention (p = 0.049) and postoperative morphine requirement (p = 0.035). No patients required urological surgical intervention at mean follow up of 1.97 years. CONCLUSIONS: This study supports the use of indwelling urinary catheterization for patients developing urinary retention after total knee arthroplasty.

Background: Obesity and hypertension and their associated health complications disproportionately affect communities of color and people of lower socioeconomic status. Recruitment and retention of these populations in research trials, and retention in weight loss trials has been an ongoing challenge. Methods: Be Fit, Be Well was a pragmatic randomized weight loss and hypertension management trial of patients attending one of three community health centers in Boston, Massachusetts. Participants were asked to complete follow-up assessments every 6-months for two years. We describe challenges encountered and strategies implemented to recruit and retain trial participants over the 24-month intervention. We also identify baseline participant characteristics associated with retention status. Retention strategies included financial incentives, contact between assessment visits, building relationships with health center primary care providers (PCPs) and staff, and putting participant convenience first. Results: Active refusal rates were low with 130 of 2,631 patients refusing participation (4.9%). Of 474 eligible persons completing telephone screening, 365 (77.0%) completed their baseline visit and were randomized into the study. The study population was predominantly non-Hispanic Black (71.2%)...

This ex post facto study (N = 209) examined the relationships between employer job strategies and job retention among organizations participating in Florida welfare-to-work network programs and associated the strategies with job retention data to determine best practices. An internet-based self-report survey battery was administered to a heterogeneous sampling of organizations participating in the Florida welfare-to-work network program. Hypotheses were tested through correlational and hierarchical regression analytic procedures. The partial correlation results linked each of the job retention strategies to job retention. Wages, benefits, training and supervision, communication, job growth, work/life balance, fairness and respect were all significantly related to job retention. Hierarchical regression results indicated that the training and supervision variable was the best predictor of job retention in the regression equation. The size of the organization was also a significant predictor of job retention. Large organizations reported higher job retention rates than small organizations. There was no statistical difference between the types of organizations (profit-making and non-profit) and job retention. The standardized betas ranged from to .26 to .41 in the regression equation. Twenty percent of the variance in job retention was explained by the combination of demographic and job retention strategy predictors...

The purpose of this study was to examine the relationship between participation in a retention program designed to promote academic and social integration and the persistence rates of first generation, low-income college students at an urban, public multiethnic university. Archival data were collected from the university’s Office of Institutional Research and the retention program office and included SAT/ACT scores, GPA, gender, ethnicity, and program participation data. A total of 292 first-generation, low-income students who were admitted to the university in the summer of 1999 were identified for the study. A group of 166 students were selected for the comparison group because they had not participated in the retention program; 126 students had participated in the retention program. Three major research questions guided this study: (a) Are there differences in persistence rates and other academic characteristics of underprepared, low-income, first generation college students who participate and do not participate in the retention program?; (b) Does involvement in the retention program predict student persistence of first generation low-income, underprepared students?, and (c) Can predictors of GPA be identified for students in the retention program using program and descriptive variables? A series of logistic regression analyses were conducted to assess the relationship between various retention services and the persistence and graduation rates of participants. The results showed that there were statistically significant relationships between participation and non-participation in the retention program and having higher GPAs and higher graduation and persistence rates. Of the four program features...

Summary Background The cementation of crowns to dental implant abutments is an accepted form of crown retention that requires consideration of the properties of available cements within the applied clinical context. Most current dental cements were developed primarily for use with natural tooth crowns, but must act in a different manner with implant components. Cements are exposed to a number of stressors that may reduce crown retention in vivo, not the least of which is occlusal loading. This study investigated the influence of compressive cyclic loading on the physical retention of cast crown copings cemented to implant abutments. Method Cast crown copings were cemented to Straumann synOcta titanium implant abutments with three different readily used and available cements. Specimens were placed in a humidifier, thermocycled and subjected to one of four quantities of compressive cyclic loading. The uniaxial tensile force required to remove the cast crown copings was then recorded. Data analysis was conducted using two-way ANOVA and paired post tests. Results Statistical analysis arising from post tests following two-way ANOVA testing revealed the mean retention values for crown copings cemented with Panavia-F cement (5.103, 2.681...

See a presentation from this author for this work: http://hdl.handle.net/10945/39528; Retaining skilled doctors in the Navy's Medical Corps has become increasingly difficult due to the Global War on Terrorism (GWOT) and lucrative positions outside the military. This thesis estimates probit models to evaluate the effect that the civilian-military pay gap has on the overall Medical Corps retention rate across 19 specialties using data gathered from Bureau of Medicine and Surgery and Medical Group Management Association for Fiscal Year (FY) 2002 to FY2011. In particular, this study measures the overall retention elasticity and elasticity estimates for three main specialty groups (primary care, surgical specialties, and other specialties) and 19 individual specialties. Furthermore, projection models are employed to predict the Medical Corps future retention rates. Finally, this study seeks to understand if the protracted GWOT has an effect on the retention behavior of the Navys Medical Corps. The results indicate that a 1% increase in the pay gap reduces the overall retention probability by 0.24%. The surgical group shows the highest retention elasticity (0.31), while the other specialties group exhibits the least responsiveness (0.19). The projection models estimate that the aggregate retention probability for FY2012 will be one percentage point lower than the actual retention rate of FY2011 (58%). Finally...

Approved for public release; distribution unlimited; Unit "retention profiles" were developed using Navy Human Resource Management Survey responses for both high and lew retention units. Although the "profiles" were found to be identical for both high and lew retention units, comparative analysis of Survey responses was found of value in assisting unit Commanding Officers in developing retention management strategies. The data utilized consisted of 28,913 respondents of the Navy Human Resource Management Survey during the second guarter of fiscal year 1978. The individual's stated career intent was regressed on the survey dimensions, indices, and guestions to further understand the dynamics of the retention decision. Unit "retention profiles" were developed as a result of stepwise discriminant analysis on the survey guestions for both high and low retention units. A detailed bibliography of employee job turnover is included as an aid to future researchers.; http://archive.org/details/evaluationofeffe00almo; Lieutenant, United States Navy; Lieutenant, United States Navy

Approved for public release, distribution is unlimited; This thesis analyzes the retention of female Naval officers, focusing on the relationship between officer selection metrics and retention beyond minimum service obligation and the effect of lateral transfers on the retention of junior officer in the Unrestricted Line. The retention analysis utilizes data from Naval Academy cohorts 1988-1991, while the lateral transfer analysis uses data from officer cohorts 1986-1991 available through the Officer Promotion History File. The retention analysis focuses on whether the elements of the Naval Academy's Whole Person Multiple (WPM) are valid predictors of graduation and fleet retention beyond minimum service requirement for female officers. Results indicate that the WPM is generally a poor predictor of female graduation and retention, a result that is contrary to previous research that used mixed gender or male-only samples. Only the Math SAT, English/Math teacher recommendation score, and athletic/non-athletic extracurricular activities score have positive and significant relationships with retention beyond minimum service requirement. Thus, it is recommended that the Naval Academy Admissions Board develop a revised selection metric for females in order to select and commission female officers with a greater propensity for career service. The lateral transfer analysis seeks to determine the characteristics of officers in the Navy's lateral transfer system. Results reveal that women are more likely than men to transfer from Unrestricted Line to Restricted Line communities. This higher likelihood of lateral transfer for women is considered a major contributor to the low retention of female officers in Unrestricted Line communities.; Lieutenant...

Institutions have implemented many campus interventions to address student persistence/retention, one of which is Early Warning Systems (EWS). However, few research studies show evidence of interventions that incorporate noncognitive factors/skills, and psychotherapy/psycho-educational processes in the EWS. A qualitative study (phenomenological interview and document analysis) of EWS at both a public and private 4-year Florida university was conducted to explore EWS through the eyes of the administrators of the ways administrators make sense of students’ experiences and the services they provide and do not provide to assist students. Administrators’ understanding of noncognitive factors and the executive skills subset and their contribution to retention and the executive skills development of at-risk students were also explored. Hossler and Bean’s multiple retention lenses theory/paradigms and Perez’s retention strategies were used to guide the study. Six administrators from each institution who oversee and/or assist with EWS for first time in college undergraduate students considered academically at-risk for attrition were interviewed. Among numerous findings, at Institution X: EWS was infrequently identified as a service...

Les dirigeants-propriétaires des petites et moyennes entreprises (PME) sont de plus en plus intéressés par la gestion des ressources humaines (GRH); certains y voient un avantage concurrentiel face à la pénurie de main-d’œuvre actuelle. Considérant que la compatibilité entre les caractéristiques des travailleurs et celles de l’organisation peut générer des résultats positifs (Kristof-Brown et Guay, 2011), notre étude s’intéresse aux pratiques de GRH associées aux valeurs au travail de la génération Y ainsi que leur effet sur la capacité des PME à attirer et retenir cette cohorte. Cette étude qualitative s’est réalisée grâce à des données primaires colligées à la suite d’entrevues avec des dirigeants de quatre PME du secteur de la construction et seize employés appartenant à la génération Y œuvrant au sein de ces entreprises. Par nos résultats, nous avons relevé que la qualité des relations, autant avec les collègues que les superviseurs, demeure généralement la principale source d’attraction et de rétention des Y dans les PME. Nos résultats soutiennent aussi que leur attraction et rétention peut être très fortement favorisée grâce à des pratiques de communication bidirectionnelle et illimitée...

De plus en plus d'intérêt est porté au recrutement d'infirmières formées à l’étranger dans plusieurs pays, surtout dans le contexte actuel de pénurie de ressources. Toutefois, il n’existe peu d’écrits sur leur expérience d’intégration ainsi que les facteurs favorisant leur rétention. L'objectif de cette thèse est d'explorer les facteurs explicatifs de la réussite de l'intégration et de la rétention des infirmières diplômées hors Québec (DHQ) dans le système de santé québécois. Cette étude s'est concentrée sur trois processus clefs, à savoir le programme de formation d'appoint, ou programme d'Intégration à la profession infirmière au Québec CWA0B0 (volet 1), la période de probation en emploi (volet 2) et la rétention en emploi des infirmières DHQ (volet 3). Afin d'explorer ceux-ci, un devis mixte, alliant entretiens individuels, groupes de discussion et questionnaires auto-administrés a été adopté. Ultimement, cette thèse a permis l'avancement des connaissances quant à l'intégration des professionnels de la santé immigrants. En effet, cette étude a permis de comprendre le processus d'intégration, définir les sous-processus qu'il sous-entend et proposer un modèle conceptuel adapté aux transitions qui leur sont associées.

EXECUTIVE SUMMARY This paper investigates the relationship between institutional characteristics (institutional selectivity, faculty and financial characteristics) and retention and 6-year graduation rates at Historically Black Colleges and Universities. Institutional financial characteristics (instructional, academic support, student services and institutional support expenditures) were examined from two perspectives: (1) The relationship between the amount of money spent per student and retention and graduation rates and (2) The relationship between the percentage of institutional expenditures and retention and graduation rates. I estimate 6-year graduation rates and 1-year retention rates in 2009 for HBCUs in the sample using multiple linear-regression. This study has two research questions: 1. Do institutional selectivity, faculty characteristics and financial characteristics spent per student significantly predict 6-year graduation rates at HBCUs and UNCF institutions? 2. Do institutional selectivity, faculty characteristics and the percentage of expenditures significantly predict first year retention rates at HBCUs and UNCF institutions? Key Findings and Implications This paper found that there is a relationship between institutional selectivity...

Perinatal depression is increasingly recognized as a significant public mental health problem; consequently, there is a major interest in developing strategies to prevent postpartum depression that may help reduce its detrimental consequences. However, the unique experiences associated with the perinatal period make it more difficult to recruit participants at this stage and to retain them over time when assessing prevention interventions. The aim of the study is to examine retention rates and predictors of retention in a longitudinal, randomized controlled trial (RCT) to prevent postnatal depression. Method Participants: Pregnant women (N = 377) at risk of depression were randomized to intervention or usual care condition and assessed during pregnancy and at 6 weeks and 4-6 months postpartum. Intervention: The intervention was designed by modifying a previously evaluated one and includes information on normal pregnancy and the postpartum period, from psychoanalytic and risk factors perspectives. It attempts to reduce depression levels by increasing positive thinking and pleasant activities, improving self-esteem, increasing self-care, learning skills to strengthen social support, and exploring unrealistic expectations about pregnancy and motherhood. It is delivered in eight two-hour weekly group sessions during pregnancy. Measures: Depressive symptoms were measured using the second edition of the Beck Depression Inventory (BDI-II); anxiety symptoms with the corresponding subscale of the Hopkins Symptoms Checklist (SCL-90) and social support with the Social Support Apgar (SSA). A short form of 12 items representing potential stressors was used as a measurement of stressful life events and the Abbreviated Version of the Dyadic Adjustment Scale (A-DAS) measured partner relationship. Results Retention rates -defined in three ways- were: (1) Total retention (percentage of participants completing the 4-6 month postpartum interview) was 41.7% (31.2% intervention and 61.4% control); (2) Retention from randomization to (a) completion of initial evaluation and attendance of > 1 intervention sessions was 42.4%; and (b) completion of initial evaluation (control) was 82.2%; and (3) Follow-up retention: (a) intervention participants attending > 1 sessions that completed the intervention as well as the 4-6 months postpartum interview was 73.5%; and (b) control participants assesses in this period was 66.6%. For those who came to at least one intervention session 83% completed the intervention. The predictors of total retention were: being single...
