As decisões de preços de venda, é uma das funções com mais relevância no ambiente empresarial para os gerentes, devido o seu carácter estratégico para o sucesso das empresas. O processo de formação de preço (FP) é fundamental para as empresas, embora apresenta graus de dificuldade e de complexidade, por implicar diversos factores. A primeira etapa para a FP consiste na estimativa correcta de custos, para obtenção de preços ideais. Para além dos custos, outros factores internos e externos devem ser analisados para que as decisões possam ser tomadas de forma correcta e obter um preço competitivo. Portanto, os gerentes precisam de informações precisas para poderem tomar decisões com segurança, levando em consideração todos os aspectos relevantes para a FP. O presente trabalho tem como objectivo principal, conhecer uma politica adequada de FP, bem como, descobrir quais os factores mais relevantes considerados na formação desses preços nas empresas e ainda conhecer quais os métodos de FP utilizado pelas empresas de importação de S.Vicente para a FP. A metodologia, consistiu primeiramente numa pesquisa bibliográfica e exploratória. Para a recolha dos dados,foram aplicados questionários com perguntas fechadas múltipla escolha, aos gerentes e aos responsáveis pelos processos de EC e FP e para complementar, foi feita uma entrevista a um especialista da área. Para a análise dos dados, foram utilizadas técnicas qualitativas e quantitativas, feito através das respostas obtidas dos questionários. Os resultados obtidos da pesquisa, mostram que o método de formação de preços de venda adoptado pelas empresas de S.Vicente, é o método baseado no custo e no mercado (método misto), ou seja, o preço é definido com base nos seus custos, mas é ajustado tendo por base o preço da concorrência. The sale prices decisions; it is one of the functions with more relevance in the managerial atmosphere for the managers, due your strategic character for the success of the companies. The process of price formation (FP) it is fundamental for the companies,although it presents degrees of difficulty and of complexity, for implicating several factors. The first stage for FP consists in estimate correct costs, to obtaining ideal prices. Besides the costs, others internal and external factors should be analyzed so that decisions can be made in a correct form to obtain a competitive price. Therefore, the managers need necessary information to make safety decisions, taking in consideration all the important aspects of FP. The main objective of this present work, is to know the appropriate politics of FP, as well as, to discover which the most important factors considered in the formation of those prices to purchases and still to know which of the FP methods used by the import companies in São Vicente. The methodology consisted firstly in a bibliographical and exploratory research. To collect the data, were applied uestionnaires with closed questions, multiple choice to the managers and the responsible for the processes of ECP and EP and to complement, it was made an interview to a specialist. For the analysis of the data, qualitative techniques were used, done through to obtained answers of the questionnaires. The results of the research, show that the method of formation of sale prices adopted for São Vicente's companies, is the method based on the cost and in the market (mixed method), in other words, the price is defined with base in the costs, but it is adjusted tends for base of the competition.

A dinâmica de desenvolvimento de Cabo Verde vem sendo uma constante, com ganhos significativos para o país, como atestam a recente adesão à Organização Mundial do Comércio, a graduação a País de Rendimento Médio e a Parceria Especial com a União Europeia. No dia 23 de Julho de 2008, Cabo Verde tornou-se no 153º Estado membro da Organização Mundial do Comércio, sendo que nesta conquista foi o primeiro país Africano e o terceiro País Menos Avançado a conseguir este importante marco via negocial. As vantagens advenientes desta adesão são muitas, sendo de destacar a maior confiança dos investidores no país ao propiciar-se a expansão do mercado e a realização de negócios num ambiente mais seguro e estável, e ainda a possibilidade de melhoria da qualidade de prestação de serviços, uma vez que tudo passou a ser norteado por padrões e regras do comércio internacional. Este trabalho foi elaborado com base em pesquisa bibliográfica e exploratória necessária à construção de um referencial teórico sobre o assunto em questão, tendo como base artigos, livros, revistas e consultas em websites. Finalizando, para avaliação, apresentamos uma componente prática com base num questionário aplicado ao tecido empresarial, com perguntas abertas e de múltipla escolha, onde os inquiridos puderam fazer a sua apreciação relativa ao processo de adesão, e às expectativas advenientes. Os resultados obtidos no final do trabalho mostraram de forma clara e inequívoca a necessidade de Cabo Verde se reorganizar, reforçar o sector privado e a competitividade das empresas, através de, designadamente: melhoria do ambiente fiscal das empresas, fomento e apoio às pequenas e médias empresas. Outrossim, há que dar seguimento as reformas no sector comercial, capacitando e formando quadros nacionais uma vez que estes desempenham um papel essencial no crescimento económico do país e permitem dar maior previsibilidade aos investidores, sendo este último um dos pilares decisivos no requisito do investimento externo. The dynamics of the development of Cape Verde is becoming a constant, with significant gains to the country, as attests the recent adhesion to the World Trade Organization, the graduation to Country of Medium Revenue, as well as the Special Partnership with the European Union. On July 23, 2008, Cape Verde became the 153rd State member of the World Trade Organization, and in this conquest it was the first African country and the third Less Advanced Country to get this mark through negotiable way. The advantages proceeding from this adhesion are many, highlighting the investors' largest trust in the country when propitiating the expansion of the market and the accomplishment of business in a safer and stable atmosphere, and still the possibility of improvement of the quality of installment of services, once everything started being guided by patterns and rules of the international trade. This work was elaborated based on bibliographical and exploratory researches necessary to the construction of the theoretical referential about the subject in question, based on articles, books, magazines and website researches. Concluding, for evaluation, we presented a practical component based on a questionnaire applied to the managerial stuff, with open and multiple choice questions, where the inquired could make his appreciation related to the adhesion process, and the proceeding expectations. The results obtained at the end of the work, showed in a clear way the need of Cape Verde to organize, to reinforce the private sector and the competitiveness of the companies, through, namely: the improvement of the fiscal atmosphere of the companies, fomentation and support of the small and medium companies. Meanwhile, it is important to continue the reforms in the commercial sector, qualifying and forming national staff once they play an essential part in the economic growth of the country and allow giving a larger previsibility to the investors, being this last one, one of the decisive pillars in the requirement of the external investment.

In order to evaluate the reaction to conspecifics scent tracks of Crocidura russula, a shrew with poorly developped territorial behaviour, simple choice tests in a Y-shaped systems were used. C. russula prefers a marked path to an unmarked one, the tracks of an unknown individual to its own, the tracks of an individual of the opposite sex to those of an individual of the same sex, and the tracks of its sexual partner to those of another individual of the same sex. The choices between two tracks gave a less obvious result than the choices between a marked path and an unmarked one. Ecological and social implications of these results are discussed.

Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae). Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L.), cashew (Anacardium occidentale L.), star fruit (Averrhoa carambola L.), guava (Psidium guajava L.), soursop (Annona muricata L.), yellow mombin (Spondias mombin L.), Malay apple (Syzygium malaccense L.), and umbu (Spondias tuberosa L.). The biological parameters were obtained by rearing the recently hatched larvae on each of the fruit kinds. Acceptance of fruits for oviposition experiment was assessed using no-choice tests, as couples were exposed to two pieces of the same fruit. The best performances were obtained with guava, soursop, and star fruit. Larvae reared on cashew and acerola fruits had regular performances. No adults emerged from yellow mombin, Malay apple, or umbu. Fruit species did not affect adult longevity, female fecundity, or egg viability. Guava, soursop, and acerola were preferred for oviposition, followed by star fruit, Malay apple, cashew, and yellow mombin. Oviposition did not occur on umbu. In general, fruits with better larval development were also more accepted for oviposition.

OBJECTIVE: To measure the in vivo variations of CYP3A activity induced by anti-HIV drugs in human immunodeficiency virus (HIV)1-positive patients. METHODS: A low oral dose of midazolam (MID) (0.075 mg) was given to the patients and the 30-min total 1-OH midazolam (1-OHMID)/MID ratio was determined. Patients were phenotyped either before the introduction of antiretroviral treatments (control group, 90 patients) or after a variable period of antiretroviral treatment (56 patients). Twenty-one subjects underwent multiple phenotyping tests (before and during the course of the treatment). RESULTS: The median MID ratio was 3.51 in the control group (range 0.20-14.6). It was 5-fold higher in the group with efavirenz (28 patients; median, range: 16.0, 3.81-367; P < 0.0001), 13-fold lower with nelfinavir (18 patients; 0.27, 0.06-36.3; P < 0.0001), 17-fold lower with efavirenz + ritonavir (three patients; 0.21, 0.05-0.47; P = 0.006), 50-fold lower with ritonavir (four patients; 0.07, 0.06-0.17; P = 0.0007), and 7-fold lower with nevirapine + (ritonavir or nelfinavir or grapefruit juice) (three patients; 0.48, 0.03-1.83; P = 0.03). CYP3A activity was lower in the efavirenz + ritonavir group (P = 0.01) and in the ritonavir group (P = 0.04) than in the nelfinavir group, although already strongly inhibited in the latter. CONCLUSION: The low-dose MID phenotyping test was successfully used to measure the in vivo variations of CYP3A activity induced by antiretroviral drugs. Efavirenz strongly induces CYP3A activity, while ritonavir almost completely inhibits it. Nelfinavir strongly decreases CYP3A activity, but to a lesser extent than ritonavir. The inhibition of CYP3A by ritonavir or nelfinavir offsets the inductive effects of efavirenz or nevirapine administered concomitantly. Finally, no induction of CYP3A activity was noticeable after long-term administration of ritonavir at low dosages (200 mg/day b.i.d.) or of nelfinavir at standard dosages (2,500 mg/day b.i.d.).

The way colleagues and supervisors acknowledge specific contribution and efforts of individuals is crucial for occupational mental health and well being. It contributes to improve the self image of employees and it gives a sense to the activities performed. We carried out a study about occupational health in police officers with a special emphasis on acknowledgment and reward. A questionnaire was sent to 1000 police officers working for a cantonal administration in Switzerland. In total, 695 participants answered the questionnaire. We used the French version of the Langner's questionnaire on psychiatric symptoms to identify cases characterized by potential mental health problems. Multiple choice items (6 modalities ranging from "not at all" to "tremendously") to measure acknowledgment were used. Answers were later dichotomized (low annoyance- high annoyance). Questions we used are: "Do you feel annoyed due to a lack of support and attention from your supervisors?" "Do you feel annoyed because the authorities (politics, judges, etc.) have a low consideration of your occupation?" "Do you feel annoyed due to a low appreciation by the public?" and "Do you feel annoyed due to a lack of acknowledgment by the hierarchy?". The score for psychiatric symptoms was high for 86 police officers for whom health might be at risk. Acknowledgment aspects associated with a high score for psychiatric symptoms are : high annoyance due to a lack of support and attention from supervisors (odds ratio [OR] 3.2, 95% confidence interval [CI] 2.0 to 5.1), high annoyance because authorities seems to have a low consideration for police officers (OR 2.7, 95% CI 1.7 to 4.3), high annoyance due to a low appreciation by the public (OR 1.8, 95% CI 1.2 to 2.9), and high annoyance due to a lack of acknowledgment by the hierarchy (OR 3.0, 95% CI 1.9 to 4.8). Preserving mental health in occupations characterized by high emotional demand is challenging. The results from our study suggest that appropriate acknowledgment might contribute to the prevention of mental health problems. Further research should address a potential causal relation of acknowledgment on mental health.

The evaluation’s overarching question was “Did the activities undertaken through the state’s LSTA plan achieve results related to priorities identified in the Act?” The evaluation was conducted and is organized according to the six LSTA priorities. The research design employed two major methodologies: 1. Data sources from Iowa Library Services / State Library of Iowa2 as well as U.S and state sources were indentified for quantitative analysis. These sources, which primarily reflect outputs for various projects, included: Statistics from the Public Library Annual Survey Statistics collected internally by Iowa Library Services such as number of libraries subscribing to sponsored databases, number of database searches, attendance at continuing education events, number of interlibrary loan transactions Evaluation surveys from library training sessions, professional development workshops and other programs supported by LSTA funds Internal databases maintained by Iowa Library Services Impact results from post training evaluations conducted by Iowa Library Services 2010 Iowa census data from the U.S. Census Bureau LSTA State Program Reports for the grant period 2. Following the quantitative analysis, the evaluator gathered qualitative data through interviews with key employees, a telephone focus group with district library consultants and two surveys: LSTA Evaluation Survey (Public Libraries) and LSTA Evaluation Survey (Academic Libraries). Both surveys provided sound samples with 43 representatives of Iowa’s 77 academic libraries and 371 representatives of Iowa’s 544 public libraries participating. Respondents represented libraries of all sizes and geographical areas. Both surveys included multiple choice and rating scale items as well as open-ended questions from which results were coded to identify trends, issues and recommendations.

This research analyses the actual use and conception of the ICT mobility that a life long learning group of students have. The students have participated in a Mobile Learning experience along an online postgraduate course, which was designed under a traditional e-learning perspective. The students received a tablet PC (iPad) in order to work at the course and also to use it in their personal and professional life. A complete and original pre-test / post-test questionnaire was applied before and after the course. This instrument was scientifically validated. Thru the questionnaire, uses tendency and students perceptions were studied. Frequencies, purposes, habits of use and valuation, as well as the device"s integration into their personal, social and professional life were studied. The analysis intents to apply the 'Social Technographics Profile" by Bernoff (2010) to classify, by profile groups, the users of the actual Internet. Finally a reflexion of the reasons and limits of the theory, in this study, and also the relation to reality is presented. The Inter-coding reliability and validity shows the possibility of applying the instrument on wider samples in order to get a closer look to the uses and actual conceptions of the ubiquitous ICTs.

The purpose of the study was to evaluate the shear bond strength of stainless steel orthodontic brackets directly bonded to extracted human premolar teeth. Fifty teeth were randomly divided into ¿ve groups: (1) System One (chemically cured composite resin), (2) Light Bond (light-cured composite resin), (3) Vivaglass Cem (self-curing glass ionomer cement), (4) Fuji Ortho LC (light-cured glass ionomer cement) used after 37% orthophosphoric acid¿etching of enamel (5) Fuji Ortho LC without orthophosphoric acid¿etching. The brackets were placed on the buccal and lingual surfaces of each tooth, and the specimens were stored in distilled water (24 hours) at 378C and thermocycled. Teeth were mounted on acrylic block frames, and brackets were debonded using an Instron machine. Shear bond strength values at fracture (Nw)were recorded. ANOVA and Student-Newman-Keuls multiple comparison tests were performed (P , .05). Bonding failure site was recorded by stereomicroscope and analyzed by Chi-square test, selected specimens of each group were observed by scanning electron microscope. System One attained the highest bond strength. Light Bond and Fuji Ortho LC, when using an acid-etching technique, obtained bond strengths that were within the range of estimated bond strength values for successful clinical bonding. Fuji Ortho LC and Vivaglass Cem left an almost clean enamel surface after debracketing.

INTRODUCTION: Delirium is a highly prevalent disorder, with serious consequences for the hospitalised patient. Nevertheless, it remains under-diagnosed and under-treated. We developed evidence-based clinical practice guidelines (CPGs) focusing on prevention, screening, diagnosis, and treatment of delirium in a general hospital. This article presents the implementation process of these CPGs and a before-after study assessing their impact on healthcare professionals' knowledge and on clinical practice. METHODS: CPGs on delirium were first implemented in two wards (Neurology and Neurosurgery) of the Lausanne university hospital. Interactive one-hour educational sessions for small groups of nurses and physicians were organised. Participants received a summary of the guidelines and completed a multiple choice questionnaire, assessing putative changes in knowledge, before and three months after the educational session. Other indicators such as "diagnosis of delirium" reported in the discharge letters, and mean duration of patients' hospital stay before and after implementation were compared. RESULTS: Eighty percent of the nurses and physicians from the Neurology and Neurosurgery wards attended the educational sessions. Both nurses and physicians significantly improved their knowledge after the implementation (+9 percentage-points). Other indicators were not modified by the intervention. CONCLUSION: A single interactive intervention improved both nurses' and physicians' knowledge on delirium. Sustained and repeated interventions are probably needed to demonstrate changes in clinical practice.

The objective of this research was to evaluate the parasitism behavior of Telenomus podisi Ashmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) on eggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternum aseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For all parasitoid species, the results demonstrated the existence of a main host species that maximizes the reproductive success. The competitive interactions among the parasitoid species were investigated in experiments of sequential and simultaneous release of different combinations of parasitoid pairs on the hosts N. viridula, E. heros and A. aseadum. Exploitative competition was observed for egg batches at the genus level (Telenomus vs. Trissolcus) and interference competition at the species level (T. basalis vs. T. urichi). Trissolcus urichi was the most aggressive species, interfering with the parasitism of T. basalis. Generally, T. basalis showed an opportunistic behavior trying to parasitise eggs after T. urichi had abandoned the egg batch. The selection of parasitoid species for use in augmentative biological control programs should take into account the diversity of pentatomids present in soybean in addition to the interactions among the different species of parasitoids.
