The Influence of the First-Year Seminar Participation on Student Retention

College student retention is a complex phenomenon influenced by a myriad of factors and with wide-ranging implications for university function. First-year seminar is one approach to increase first-year student retention through involvement, engagement, and integration. This quantitative study examines the influence of first-year seminar on retention of first-year, full-time, four-year degree-seeking students who matriculated during the fall 2016, 2017, 2018 semester and remained enrolled for fall 2017, 2018, 2019 semester at six institutions in two Northwest states in the United States. This study utilized an odds ratio to investigate whether first-year seminar participation had a statistically significant influence on the probability of students being retained at the targeted institutions. The results of this study were not statistically significant indicating that first-year seminar participation did not have a statistically significant effect on the probability of students being retained at the study\u27s institutions. The odds ratio value of 1.33 indicated that students who participated in first-year seminar had 95% confidence interval of 1.27-1.39 result in not having a statistically significant effect on the probability of students being retained at the study\u27s institutions. Future research could replicate the study at all public four-year universities in a bigger population ideally nationwide. Additionally a mixed methods approach may help to identify underlying factors and confounding variables that contribute to the results of this research and clarify why students who attended the first-year seminar did not return for the next fall semester

Optimization the machinability and mechanical properties of PM steel components by development a new machining additive

L'usinabilité des composants en acier PM est nettement inférieure à celle des aciers corroyés en raison de la présence de porosité résiduelle et de l'hétérogénéité de leur microstructure. Les problèmes liés à l'usinabilité constituent une part importante des coûts de production globaux des pièces en acier PM. La stratégie la plus populaire pour améliorer leur usinabilité consiste à mélanger un composé chimique, tel que MnS, MoS2 ou BN-h, à la poudre de base. Ces améliorateurs d'usinabilité améliorent le comportement d'usinage des aciers PM en diminuant les forces de coupe impliquées dans la formation de copeaux et en lubrifiant la surface de l'outil de coupe, ce qui en retour réduit à la fois l'usure en flanc et l'usure en cratère. Cette étude met en évidence une nouvelle approche pour développer des activateurs d'usinabilité conçus pour maximiser l'usinabilité des composants d'acier PM sans affecter les propriétés mécaniques ni la résistance à la corrosion. Ainsi, il a été décidé de revêtir les particules de MnS d'une couche de nickel pouvant agir comme une barrière pour neutraliser leur nature hygroscopique et augmenter la résistance à la corrosion des pièces en acier PM. De plus, il a été prévu que les propriétés mécaniques peuvent être améliorées en raison de la formation de liaisons métallurgiques entre le revêtement de nickel des particules de MnS et la matrice d'acier, tandis que le MnS améliore simultanément l'usinabilité de la pièce en acier PM. Une comparaison avec des additifs d'usinage commerciaux a été effectuée en termes d'usinabilité et de propriétés mécaniques. Il a été constaté que la résistance à la corrosion des échantillons contenant du MnS recouvert de nickel était excellent et identique à celle des échantillons sans additifs. De plus, les propriétés mécaniques ne sont pas affectées par la présence de l'additif nouvellement développé par rapport à ce qui a été mesuré lorsque le MnS a été utilisé. Enfin, la caractérisation de l'usinabilité a montré que l'ajout du MnS revêtu de nickel comme additif d'usinage pouvait améliorer l'usinabilité aussi bien que le MnS.Machinability of PM steel components is significantly lower than that of wrought steels due to the presence of residual porosity and the heterogeneity of their microstructure. Machinability-related issues constitute a significant portion of the overall production costs of PM steel parts. The most popular strategy for improving their machinability involves admixing a chemical compound, such as MnS, MoS₂ or BN-h, to the base powder. These machinability enhancers improve the machining behavior of PM steels by decreasing the cutting forces involved with chip formation and by lubricating the surface of the cutting tool, which in return, reduces both flank wear and crater wear. This study highlights a novel approach for developing machinability enhancers engineered to maximize the machinability of PM components without affecting their mechanical properties nor corrosion resistance. Thus, it was decided to coat MnS particles with a nickel layer that can act as a barrier to neutralize their hygroscopic nature and increase the corrosion resistance of PM steel parts. Moreover, it was anticipated that mechanical properties could be improved due to the formation of metallurgical bonds between the nickel coating of the MnS particles and the steel matrix, while the MnS core of the additive would improve machinability of the PM steel component simultaneously. A comparison with commercial machining additives was performed in terms of both machinability and mechanical properties. It was found that the corrosion resistance of the samples containing nickel-coated MnS was excellent and identical to that of samples without additives. Moreover, mechanical properties are not affected by the presence of the newly developed additive compared to what was measured when MnS was used. Finally, machinability characterization showed that the addition of the nickel-coated MnS as a machining additive could improve machinability as well as MnS does

Stage d'immersion brève en soins primaires ambulatoires de médecine générale (quels objectifs de formation et moyens pédagogiques pour des étudiants en troisième année de médecine?)

Objectif de l'étude : La formation des externes en médecine oriente largement les étudiants vers les spécialités médico-chirurgicale en raison notamment des stages s'effectuant au sein de services hospitaliers au cours de leur cursus. Etant actuellement impossible de mettre en place un stage d'externat à temps plein en médecine générale, nous envisageons donc la mise en place d'un stage d'immersion brève en soins primaires ambulatoires de médecine générale en troisième année des études médicales. Pour ce faire, des objectifs de formation et de moyens pédagogiques doivent être définis, ce qui a été l'objet de notre travail. Matériel et méthode : Entre juillet et novembre 2012, nous avons réalisé successivement deux procédures delphi : deux questionnaires ont été soumis par mail grâce au serveur Google Document à quatorze experts - enseignants en médecine générale de Belgique (Liège), Suisse (Lausanne), et France (Rouen). Le premier questionnaire était composé de seize propositions d'objectifs de formation élaboré à partir des grands référentiels de la WONCA.ROUEN-BU Médecine-Pharmacie (765402102) / SudocSudocFranceF

Catheter associated infections in hemodialysis patients.

Hemodialysis catheter related infections (HCRI) are one of the major causes of increasing mortality, morbidity and cost of therapy in hemodialysis patients. Prevention of HCRI requires the identification of predisposing risk factors. To determine the frequency of HCRI risk factors, we studied 116 patients (54 male, mean age of 49.5+/-16 years) patients with HCRI between 2003-2004. Forty one percent of the patients were diabetic. There was a history of previous catheter placement and infection in 41 and 32 of patients, respectively. Pathogenic organisms isolated from blood cultures included Staphylococcus-aureus 42, Coagulase-negative Staphylococci 20, E. Coli 19, Enterococci 7, Streptococcus D 7, Pseudomonas aeruginosa 4, and Klebsiella 1. Bacterial resistance to vancomycin and amikacin was present in 7 and 4 of the cases, respectively. Hemodialysis catheter related blood borne infections comprised 67 of the total blood-borne infections in our hospital. No significant statistical association was found between HCRI and age, gender, diabetes mellitus, serum albumin level <30 g/L, leukocyte count, erythrocyte sedimentation rate, anatomical location of catheter, mean duration of antibiotic therapy, mean catheter duration, frequency of hemodialysis sessions, pathogenic organisms, and history of previous catheter infection. We conclude that the prevalence of pathogenic organisms of HCRI were similar to previous studies. However, bacterial resistance to antibiotics was low. The mean duration of catheter usage was longer than previously reported

Designing a Conceptual Model of perceived social media advertising deception: using grounded theory approach

The growing evolution of social networks with intensified role in the business world and consequently in the advertising in one hand, and the ease of deception in such emerging media on the other hand, have increased the prevalence of deceptive advertising and false claims in the communication and commercial media. In this way, it is difficult for the audiences of social media ads to distinguish between the truthful and deceptive advertising and this can lead to distrust to social media advertising and reduced sales. In this regard, the present research aimed at providing a model for the perceived deception of social media advertising using grounded theory. For the purpose, in-depth and semi-structured interviews were performed among 15 people who had past deception related experiences in their purchase from social networks. Data analysis was undertaken using open coding method and MAXQDA 2020 software. Finally, the research conceptual model was designed based on 8 main categories, 15 sub-categories, and 71 concepts, and it was revealed that social media perceived usefulness and social media ads characteristics as “causes”, and media characteristics as “covariance” were effective on perceived deception. In this regard, customer knowledge and perceived trust were considered as “contingencies”. Consumer attitude was recognized as “condition”, and consumer characteristics was presented as contextual factor for such a process resulting in the occurrence of consumer psychological damage known as individual consequence of social media ads perceived deception
