Relationships Exist Between Chemistry Self-Efficacy in College Students and Academic Outcomes in Chemical Education

Introductory and preparatory chemistry courses hold a particular importance to students across a wide range of academic specialties and majors. In addition to serving as a potential primer for students interested in the possibility of majoring in chemistry, introductory and preparatory chemical education has been actively integrated into the curriculum of other fields within the natural science spectrum (such as biology and physics). Additionally, under the umbrella of requisite coursework, it has gained a strong pertinence to applied sciences such as nursing, engineering, and exercise physiology (Tai, Sadler, and Loehr 2005)

Art Therapists’ Perceptions of What Happens When They Create Art Alongside Their Clients in the Practice Of Group Therapy

Although case studies and personal accounts since the founding of the art therapy field discussed creating art alongside clients as a valuable practice, few systematic studies have explored this method. This collaborative art-based dissertation explored art therapists’ perceptions of two research questions: (1) What happens when art therapists create art alongside their clients in their group art therapy practices? and (2) What is gained and what is lost when they engage in this practice? Four group art therapists (3 females, 1 male) with 5 to 31 (median 8.5) years of experience contributed as co-researchers. They participated in 6 hours of semistructured interviews that incorporated art-making and discussion. As the researcher, I used personal response art-making, creative writing, painting, and poetic responses to gain a holistic sense of the inquiry and generate four video summations. These summations identify and present the individual co-researchers’ ideas, thoughts, gestures, phrases, and concepts related to the research questions. Finally, I created a culminating video to synthesize outcomes from work with all co-researchers. The outcomes suggest that creating art alongside clients affects four interrelated aspects of group art therapy: (a) developing an egalitarian group environment, (b) expressing authentic leadership, (c) augmenting therapist presence, and (d) boosting group member engagement. Three potential challenges of the alongside approach are (a) delayed therapist responses, (b) intimidating clients with artistic skills, and (c) decreased ability to recall sequential details related to construction of imagery. Further, methods to transform these risks into positive therapeutic encounters and benefits of creating art alongside group members emerged in more detail than in previous four essential skills: (a) multitasking, (b) shifting awareness, (c) letting go of control, and (d) media awareness. The dissertation adds the term companioning art-making to the literature. This inclusive term emphasizes the practice of authentically making art in the presence of group members

Kinematic Analysis of a Continuum Parallel Robot

Conference Paper presented at EUCOMES 2016 held in Nantes, France, from 20 to 23 September 2016Continuum Parallel Robots are mechanical devices with closed loops where kinematic pairs have been eliminated and motion is obtained by large deformations of certain elements. Most compliant mechanisms use notches in thick elements to produce the effect of kinematic pairs. A few are designed so that slender elements can deform and produce the desired motion. Some microelectromechanical systems have used this principle to create bistable planar mechanisms. The purpose of this work is to extend such principle in the field of macro mechanisms for manipulation. The aim is to design the counterparts to some classical parallel manipulators solving the corresponding kinematic problems. In doing this, the authors will have to work out the most efficient way to solve a position problem where geometry and forces are involved. Such compliant mechanisms could be combined in the future with tensegrity systems to enhance the available workspace. In this first report, we will focus on the simplest planar parallel mechanism of two degrees of freedomThe authorswish to acknowledge the financial support received fromthe Spanish Government through theMinisterio de Economía y Competitividad (Project DPI2015-64450-R) and the Regional Government of the Basque Country through the Departamento de Educación, Universidades e Investigación (Project IT445-10) and UPV/EHU under program UFI 11/29.

Estudo da Chorisia speciosa e outras fibras vegetais como sorventes para o setor de petróleo

Orientadora: Thais H. D. SydenstrickerCo-orientador: Sandro C. AmicoDissertaçao (mestrado) - Universidade Federal do Paraná, Setor de Tecnologia, Programa de Pós-Graduaçao em Engenharia - PIPE. Defesa: Curitiba, 2005Inclui bibliografiaÁrea de concentraçao: Engenharia e ciencia de materiaisResumo: Derramamento de óleo em águas constitui uma grande preocupação global e vários processos físicos, químicos e biológicos vêm sendo usados para recuperar, remover ou degradar a poluição de óleo. Tai s derramamentos não só representam uma grande perda de óleo como também um grande efeito negativo ao meio ambiente. A água poluída por óleo afeta a aeração e a iluminação do curso d'água devido à formação de um filme de óleo insolúvel na sua superfície, le vando à efeitos negativos na fauna e na flora, além de inutilizar dezenas, ou até centenas de metros cúbicos de água para o consumo humano. Vários sistemas comerciais vêm sendo desenvolvidos para o controle desses derramamentos, incluindo o uso de sorventes. O objetivo deste trabalho foi utilizar materiais vegetais como sorventes alternativos de baixo custo para a remoção do óleo cru de derramamento em águas. Seis tipos de sorventes vegetais foram avaliados: Chorisia speciosa St. Hill conhecido por paina, Luffa cylindrica (esponja vegetal), serragem, sisal ( Agave sisalana ), fibra de coco (Cocos nucifera ), e resíduos vegetais. As fibras vegetais foram moídas, homogeneizadas e classificadas e grande parte dos ensaios foram realizados com a faixa granulométrica de 850 ?m a 1700 ?m. Os testes de sorção foram realizados em água deionizada e em água marinha artificialmente preparada, em diferentes temperaturas (5 a 50ºC) e condições de pH (5 a 8), e em sistema estático e agitado. A quantidade de água simultaneament e sorvida pelas fibras foi investigada em testes de destilação do sorvente impregnado de óleo e por testes de sorção na ausência de água. A capacidade de sorção das diferentes fibras seguiu a tendência geral: Paina > Sisal e Serragem > Coco > Bucha vegetal > rejeitos folhosos, e a capacidade de sorção aumentou com a redução da granulometria. A paina mostrou uma rápida e excelente capacidade de sorção, alcançando 85 g de óleo/g de sorvente, que foi justificada com base em micrografias e no elevado grau de hi drofobicidade desta fibra. Testes de Flutuosidade e densidade foram também realizados para avaliar a adequação das fibras para a aplicação pretendida. Palavras-chaves: Fibras Vegetais, Sorção, Derramamento e Petróleo.Abstract: Oil spill in waters are a major global concern and various physical, chemical and biological processes have been used to recover, remove or degrade oil pollution. Such spills not only represent a great loss of oil but also have a major negative effect on the environment. Pollution by oil affects aeration and illumination of the water stream due to the formation of an insoluble oil film on its surface, leading to negative effects on natural fauna and flora, not to mention dozens, or even hundreds of cubic meters of still water rendered useless for human intake. Various commercial systems have been developed to control these spills, including the use of sorbents. The aim of this work was to use natural materials as low cost alternative sorbents for the removal of crude oil from water. Six types of vegetable sorbents were used, namely: mixed leaves residues, Luffa cylindrica (spounge-gourd), Coir fibers ( Cocos nucifera ), mixed sawdust, sisal ( Agave sisalana) and Chorisia speciosa St. Hill known as silk floss. The vegetable fibers were mi lled, mixed and classified and the sorption tests mostly used fibers of a granulometric size range of 850 ?m - 1700 ?m. Sorption tests were conducted in deionized and artificial marine water medium, at different temperatures (5 -50ºC) and water pH (from 5 t o 8), with and without agitation. Water intake by the fibers was investigated by tests in dry conditions and distillation of the impregnated sorbent. The sorption capacity of the fibers followed the general trend: Silk floss > Sisal and Sawdust > Coir fibe r > Sponge gourd > Leaves residues, and the s orption capacity was shown to increase by reducing granulometry. The silk -floss showed a very fast and high oil sorption capacity of approximately 85 g oil/g sorbent and this was explained in the view of micrographs and fiber degree of hydrophobicity. Specific gravity measurements and buoyancy tests were also used to evaluate the suitability of the fibers for the intended application. Key-words: Vegetable Fibers, Sorption, Spills and Crude Oil

Not all developmental assets are related to positive health outcomes in college students

<p>Abstract</p> <p>Background</p> <p>The purpose of this investigation was to model the relationships between developmental assets, life satisfaction, and health-related quality of life (HRQOL) among a stratified, random sample (<it>n </it>= 765, 56% response rate) of college students.</p> <p>Methods</p> <p>Structural equation modeling techniques were employed to test the relationships using Mplus v4.21; Model evaluations were based on 1) theoretical salience, 2) global fit indices (chi-square goodness of fit, comparative fit index: CFI and Tucker-Lewis Index: TLI), 3) microfit indices (parameter estimates, root mean squared error of approximation: RMSEA and residuals) and 4) parsimony.</p> <p>Results</p> <p>The model fit the data well: χ²(<it>n </it>= 581, 515) = 1252.23, CFI = .94, TLI = .93 and RMSEA = .05. First, participants who reported increased Family Communication also reported higher levels of life satisfaction.

While the findings for Family Communication were expected, the findings for Non-Parental Role Models suggest interactions with potential role models in college settings may be naturally less supportive. Future Aspirations findings suggest college students may harbor a greater temporal urgency for the rigors of an increasingly competitive work world. In both cases, these assets appear associated with increased poor mental HRQOL days.</p

Long-term ustekinumab therapy of psoriasis in patients with coexisting rheumatoid arthritis and Sjögren syndrome. Report of two cases and review of literature

Background: Inteleukin (IL)12 and IL23 are two main cytokines involved in the pathogenesis of immune-mediated disease. IL12 is produced by macrophages and B lymphocytes and mediates differentiation of Th1 lymphocytes, while IL23 is a pro-inflammatory cytokine essential for the differentiation of Th17 cells. Ustekinumab is a human monoclonal antibody directed against the p40 protein subunit shared by IL12 and IL23, therefore it blocks the signal transmission of both cytokines. Main observations: We present two cases and discuss the long-term efficacy of ustekinumab as a treatment of psoriasis in patients affected by autoimmune diseases, rheumatoid arthritis and Sjögren’s syndrome, who presented with severe psoriasis after anti-TNF treatment. Conclusions: To the best of our knowledge, these are the first cases reported in the literature describing the long-term good efficacy of ustekinumab not only on paradoxical forms of psoriasis induced by anti-TNF-α drugs, but also on the articular involvement in a patient affected by RA and in a patient affected by Sjögren syndrome

Use of biological drugs in patients with psoriasis and psoriatic arthritis in italy: Results from the PSONG survey

This Italian multicenter retrospective study compared the drug survival and efficacy of differentanti-TNF agents in psoriasis (PsO) and psoriatic arthritis (PsA) patients. A database of PsO/PsApatients treated with adalimumab, etanercept, and infliximab from May 2013 to May 2014 wasanalyzed. PASI 75, 90, and 100 was calculated at each time point to evaluate efficacy. Drug sur-vival rate and probability of maintaining PASI response were evaluated. The impact of dependentvariables on probability of PASI 75 loss was evaluated by logistic regression. 1,235 patients wereincluded, 577 with PsO and 658 with PsA. Highest survival rates were observed with adalimumabfollowed by etanercept and infliximab in PsO and PsA patients. The probability of maintainingPASI response was significantly higher for adalimumab followed by infliximab. For PsO patients,the odds of losing PASI 75 was higher in etanercept-treated patients (OR: 8.1; 95% CI: 4.2–15.6,p<.001) or infliximab (OR: 6.6; 95% CI: 2.6–16.3,p<.001) vs. adalimumab. Likewise, for PsApatients the odds of losing PASI 75 was higher in etanercept-treated patients (OR: 2.3; 95% CI:1.4–3.8,p5.01) or infliximab (OR: 2.2; 95% CI: 1.1–4.1,p5.018) vs. adalimumab. Adalimumabcould be the best therapeutic option over other anti-TNF agents for the treatment of PsO and PsApatients

Aplicação de práticas integrativas e complementares em estudantes de enfermagem: revisão integrativa da literatura

In view of the disorders that can be experienced by students during the Nursing course and in order to encourage discussions on integrative and complementary practices in health (PICS), it is justified to carry out research that seeks to characterize the application of these practices in this population. That said, the aim of this study was to identify, in the scientific literature, the main PICS that have been applied to nursing students. This is an integrative literature review, carried out in the SciELO, LILACS, MedLine and PubMed databases, during the months of October to December 2021. Based on the guiding question “What integrative and complementary practices have been applied to nursing students?”, 561 articles were identified; however, after selective and critical analysis, 16 articles made up this review. The most applied PICS in nursing students were music therapy (n=7) and mindfulness (n=3); who sought, among other things, to reduce anxiety (n=7) and stress (n=5). However, studies are needed to assess the impact of the application of PICS in this population. Thus, it will be possible to certify its effects and encourage its use in the face of disorders commonly experienced by nursing students.Diante das desordens que podem ser experienciadas por estudantes no decorrer do curso de Enfermagem e visando fomentar as discussões sobre práticas integrativas e complementares em saúde (PICS), justifica-se a realização de pesquisas que busquem caracterizar a aplicação dessas práticas nessa população.

Trata-se de uma revisão integrativa da literatura, realizada nas bases SciELO, LILACS, MedLine e PubMed, durante os meses de outubro a dezembro de 2021. A partir da questão norteadora “Quais práticas integrativas e complementares vêm sendo aplicadas em estudantes de enfermagem?”, foram identificados 561 artigos; contudo, após análise seletiva e crítica, 16 artigos compuseram esta revisão. As PICS mais aplicadas em estudantes de enfermagem foram a terapia pela música (n=7) e o mindfulness (n=3); que buscavam, dentre outros aspectos, a redução da ansiedade (n=7) e do estresse (n=5). São necessários, contudo, estudos que avaliem o impacto da aplicação das PICS nesta população. Assim, será possível certificar seus efeitos e encorajar sua utilização diante de desordens comumente experienciadas por estudantes de enfermagem
