Aportes teóricos e metodológicos para a constituição de um grupo de planejamento conjunto com docentes da licenciatura em física

We present in this paper parts of the results of a research that had the intention to promote a space of communicative interaction among teachers of an undergraduate Course of Physics Teaching so they could plan their courses together. From the theoretical recommendations of the Theory of Communicative Action , by Jürgen Habermas , it was possible to draw a way of rationality crisis in training degree in physics in Brazil and then propose the creation of a Joint Planning Group (JPG) with teachers of specific nature disciplines of physics and disciplines about physics teaching. They start a joint discussion about the relationship among the disciplines in delivering of a project for future high school teachers' training. All meetings developed over a school year in the GPC were recorded, transcribed and analyzed with a part of a methodological analysis feature of the intersubjective interactions. This methodology was developed specifically for the research. The conclusions are related to the joint constructions developed by the JPG, its local contexts and the possibility of extension of this group. The joint constructions undertaken in the group point to the defense of the formation of JPG in the formation of the professors who teach these courses.

Defining Sales and Operations Planning Process in an Environmental Management Company

Sales and operations research publications have increased significantly in the last decades. The concept of sales and operations planning (S&OP) has gained increased recognition and has been put forward as the area within Supply Chain Management (SCM). Development of S&OP is based on the need for determining future actions, both for sales and operations, since off-shoring, outsourcing, complex supply chains and extended lead times make challenges for responding to changes in the marketplace when they occur. Order intake of the case company has grown rapidly during the last years. Along with the growth, new challenges considering data management and information flow have arisen due to increasing customer orders. To manage these challenges, case company has implemented S&OP process, though initial process is in early stage and due to this, the process is not managing the increased customer orders adequately. Thesis objective is to explore extensively the S&OP process content of the case company and give further recommendations. Objectives are categorized into six different groups, to clarify the purpose of this thesis. Qualitative research methods used are active participant observation, qualitative interviews, enquiry, education, and a workshop. It is notable that demand planning was felt as cumbersome, so it is typically the biggest challenge in S&OP process. More proactive the sales forecasting can be, more expanded the time horizon of operational planning will turn out. S&OP process is 60 percent change management, 30 percent process development and 10 percent technology. The change management and continuous improvement can sometimes be arduous and set as secondary. It is important that different people are required to improve the process and the process is constantly evaluated. As well as, process governance is substantially in a central role and it has to be managed consciously. Generally, S&OP process was seen important and all the stakeholders were committed to the process. Particular sections were experienced more important than others, depending on the stakeholders’ point of views. Recommendations to objective groups are evaluated by the achievable benefit and resource requirement. The urgent and easily implemented improvement recommendations should be executed firstly. Next steps are to develop more coherent process structure and refine cost awareness. Afterwards demand planning, supply planning, and reporting should be developed more profoundly. For last, information technology system should be implemented to support the process phases.

O gerenciamento de projetos e o planejamento de operações de guerra do Exército brasileiro

A presente pesquisa teve como objetivo verificar como a metodologia de gerenciamento de projetos, preconizada pelo Project Management Institute – PMI poderia contribuir para a modernização da metodologia de planejamento das operações de guerra do Exército Brasileiro. Para tanto, desenvolveu-se um estudo comparativo entre os processos dos grupos de iniciação e de planejamento definidos pelo PMI no seu Guia do Conhecimento em Gerenciamento de Projetos – PMBOK e o processo de planejamento de operações de guerra do Exército Brasileiro denominado Estudo de Situação. O trabalho foi desenvolvido com base em pesquisa bibliográfica e documental que contemplou renomados autores como Kerzner, Cleland, Vargas, Lima, Maximiano, Valeriano, Prado e Xavier, além dos manuais doutrinários do Exército Brasileiro pertinentes ao tema abordado e o próprio PMBOK. Contextualizando o trabalho foi feita a equiparação de uma operação militar de guerra a um projeto civil, e a caracterização do Estudo de Situação como um processo de planejamento e tomada de decisão equivalente ao conjunto de processos dos grupos de iniciação e de planejamento do gerenciamento de projetos. No estudo realizado verificou-se que as áreas de Custos, de Recursos Humanos e de Aquisições, em função das peculiaridades que envolvem uma operação de guerra são tratadas de forma tão diferenciadas do gerenciamento de projetos que não poderiam ser incluídas no estudo. Além disso, pôde-se constatar que o processo de planejamento militar é executado com uma grande parcela de intuição decorrente da aplicação de conhecimento tácito por parte dos seus executantes, o que não ocorre no gerenciamento de projetos onde o uso de um grande número de ferramentas de base lógica e matemática dá ao processo de planejamento dos projetos um maior grau de imparcialidade e precisão. Verificou-se também que o processo de planejamento militar produz um grande número de documentos gráficos que permitem uma “visão gráfica” de várias áreas ou aspectos do problema que, por sua vez, facilitam o uso da intuição na tomada de decisão. Enfim, depois de identificados os processos de gerenciamento de projetos que interessavam ao estudo e as peculiaridades da metodologia de planejamento em uso no Exército Brasileiro, chegou-se a conclusão, como se havia suposto, que a metodologia de gerenciamento de projetos efetivamente possui recursos que podem contribuir para a modernização do processo de planejamento de operações de guerra do Exército Brasileiro denominado Estudo de Situação. Esses recursos estão relacionados na conclusão do trabalho.

Formaldehyde's genotoxicity effects in pathology anatomy technologists and medical pathologists

Formaldehyde (FA) had been considered to be carcinogenic by the International Agency for Research on Cancer (group1), on the basis of sufficient evidence both in humans and in experimental animals, making it a subject of major environmental concern, especially in the occupational context. Manifold in vitro studies clearly indicated that FA is genotoxic, inducing various genotoxic effects in proliferating cultured mammalian cells. Cytokinesis-blocked micronucleus (CBMN) assay is used extensively in molecular epidemiology, and the chromosomal alterations most reported and studied by the CBMN are: micronucleus (MN), nucleoplasmic bridges (NPB) and nuclear buds (NBUDs). The pathology anatomy laboratories are work places that manipulate routinely FA and pathology anatomy technologists and pathologists contact daily with this chemical compound particularly in the macroscopic exam and grossing procedures. The aim of this study was to identify genotoxicity biomarkers in the set workers groups, such as micronucleus (MN), nucleoplasmic bridges (NPB) and nuclear buds (NBUD) in peripheral blood lymphocytes.

Cambios emocionales y alteraciones en la Inmunoglobulina A (IgA) tras el tratamiento psicológico en mujeres víctimas de violencia doméstica

The aim of this study was to determine the benefits of a psy-chological treatment in women victims of mistreatments in psychological health and in the immune system. The participants in this study were 60 women users of the Equality Area of the City Council of Malaga. We set two groups of women up in relation of whether the women attended or not to the given therapy. Psychological variables (self-esteem, depression and anxiety) and levels of Inmunoglobulin A were evaluated before and after the treatment. The results showed differences between all the vari-ables before and after the treatment, with better valuation after the treat-ment. These differences were not shown in women that did not assist to the therapeutic sessions, and even, the values of depression and immu-noglobulin A levels were worse. We found also differences in the values of these variables when the two groups were compared. Women that re-ceived the treatment showed fewer indicators of psychological alterations and higher levels of immunoglobulin A than the women that did not assist to the sessions; in the pre-treatment these differences were not shown. This study enhances the significance of the psychological treatment for psychological and physic health in women victims of

Prediction of crude protein and classification of the growth stage of wheat plant samples from NIR spectra

Near-infrared spectroscopy (NIRS) was used to analyse the crude protein content of dried and milled samples of wheat and to discriminate samples according to their stage of growth. A calibration set of 72 samples from three growth stages of wheat (tillering, heading and harvest) and a validation set of 28 samples was collected for this purpose. Principal components analysis (PCA) of the calibration set discriminated groups of samples according to the growth stage of the wheat. Based on these differences, a classification procedure (SIMCA) showed a very accurate classification of the validation set samples : all of them were successfully classified in each group using this procedure when both the residual and the leverage were used in the classification criteria. Looking only at the residuals all the samples were also correctly classified except one of tillering stage that was assigned to both tillering and heading stages. Finally, the determination of the crude protein content of these samples was considered in two ways: building up a global model for all the growth stages, and building up local models for each stage, separately. The best prediction results for crude protein were obtained using a global model for samples in the two first growth stages (tillering and heading), and using a local model for the harvest stage samples.

Pienten osakeyhtiöiden verosuunnittelu - empiirinen tutkimus

Tutkimuksen aiheeksi valittiin pienten osakeyhtiöiden verosuunnittelu. Tutkimuksen teoreettinen viitekehys perustui aiempaan laskentatoimen empiiriseen verotutkimukseen sekä laskentatoimen kontingenssiteoreettiseen pk-yritystutkimukseen. Tutkimusaineistoa kerättiin kyselytutkimuksella sekä tilinpaatostietokannasta Voitto+. Kyselytutkimukseen valittiin satunnaisotannalla osakeyhtiötä Etelä Suomen läänistä, joiden liikevaihto oli välillä 1 10 milj. euroa. Kyselytutkimukseen vastasi 216 yritystä, jolloin vastausprosentiksi saatiin 21,3. Kerättyä tutkimusaineistoa analysoitiin kvantitatiivisin menetelmin. Pääasiallisina analysointimenetelminä käytettiin pääkomponentti-, klusteri- ja regressioanalyysiä. Tutkimuksen tavoitteeksi asetettiin kokonaiskuvan muodostaminen pienten osakeyhtiöiden verosuunnittelusta, verosuunnittelun asemointi osaksi yrityksen taloushallintoa sekä yritysten erilaisia verosuunnittelustrategioita selittävien tekijöiden tunnistaminen. Tutkimusaineistosta kyettiin tunnistamaan pääkomponenttianalyysillä neljä erilaista verosuunnitteluorientaatiota: valistunut, resursseja panostava, veroa minimoiva sekä vastuuta ulkoistava. Verosuunnitteluorientaatioita kuvaavien muuttujien avulla yritykset jaettiin klusterianalyysilla neljään ryhmään. Yritykset nimettiin ryhmien luonteidensa mukaisesti verosuunnittelun osalta vastuun ulkoistajiksi, veron minimoijiksi, veroneutraaleiksi sekä valistuneiksi. Verosuunnitteluvastuuta ulkoistavien yritysten ryhmään kuului n. 57 % kyselyyn vastanneista yrityksistä. Tulos osoittaa sen, että yritykset ovat verosuunnittelun osalta paljolti riippuvaisia taloushallinnon sidosryhmistä, tilitoimistoista sekä tilintarkastajista. Tulosta voidaan tulkita myös niin, että taloushallinnon sidosryhmien ammattitaito verosuunnittelun osalta on keskeisessä roolissa, kun arvioidaan, miten yritysten välinen tasapuolisuus verotuksen osalta käytännössä toteutuu. Yritysten erilaisia verosuunnitteluorientaatioita, jotka kuvasivat yritysten verosuunnittelustrategioita, ei kyetty kvantitatiivisilla analyyseilla selittämään samoilla muuttujilla kuin yritysten erilaisia johdon laskentatoimen käytänteitä. Tätä havaintoa tulkittiin siten, että vaikka verosuunnittelu on selkeästi osa yrityksen taloushallintoa, sen asema ei ole johdon laskentatoimen käytänteiden tavoin taloushallinnon ytimessä. Tutkimuksessa kyettiin tuottamaan tuloksia, jotka kontribuoivat aiempia laskentatoimen empiirisiä verotutkimuksia, ja joilla on uutuusarvoa käytännön toimijoiden näkökulmasta.

Effects of dietary restraint and oral contraceptives on bone strength and bone turnover in young women

ABSTRACT Introduction The purpose of this study was to assess specific osteoporosis-related health behaviours and physiological outcomes including daily calcium intake, physical activity levels, bone strength, as assessed by quantitative ultrasound, and bone turnover among women between the ages of 18 and 25. Respective differences on relevant study variables, based on dietary restraint and oral contraceptive use were also examined. Methods One hundred women (20.6 ± 0.2 years of age) volunteered to participate in the study. Informed written consent was obtained by all subjects prior to participation. The study and all related procedures were approved by the Brock University Research Ethics Board. Body mass, height, relative body fat, as well as chest, waist and hip circumferences were measured using standard procedures. The 10-item restrained eating subscale of the Dutch Eating Behaviour Questionnaire (DEBQ) was used to assess dietary restraint (van Strien et al., 1986). Daily calcium intake was assessed by the Rapid Assessment Method (RAM) (Hertzler & Frary 1994). Weekly physical activity was documented by the 4-item Godin Leisure-Time Exercise Questionnaire (Godin & Shephard 1985). Bone strength was determined from the speed of sound (SOS) as measured by QUS (Sunlight 7000S). SOS measurements (m/s) were taken of the dominant and non-dominant sides of the distal one third of the radius and the mid-shaft of the tibia. Resting blood samples were collected from all subjects between 9am and 12pm, in order to evaluate the impact of lifestyle factors on biochemical markers of bone turnover. Blood was collected during the early follicular phase of the menstrual cycle (approximately days 1-5) for all subjects. Samples were centrifliged and the serum or plasma was aliquoted into separate tubes and stored at -80°C until analysis. The bone formation markers measured were Osteocalcin (OC), bone specific alkaline phosphatase (BAP) and 25-OH vitamin D. The bone resorption markers measured were the carboxy (CTx) and amino (NTx) terminal telopeptides of type-I collagen crosslinks. All markers were assessed by ELISA. Subjects were divided into high (HDR) and low dietary restrainers (LDR) based on the median DEBQ score, and also into users (BC) and non-users (nBC) of oral contraceptives. A series of multiple one way ANOVA's were then conducted to identify differences between each set of groups for all relevant variables. A two-way ANOVA analysis was used to explore significant interactions between dietary restraint and use of oral contraceptives while a univariate follow-up analysis was also performed when appropriate. Pearson Product Moment Correlations were used to determine relationships among study variables. Results HDR had significantly higher BMI, %BF and circumference measures but lower daily calcium intake than LDR. There were no significant differences in physical activity levels between HDR and LDR. No significant differences were found between BC and nBC in body composition, calcium intake and physical activity. HDR had significantly lower tibial SOS scores than LDR in both the dominant and non-dominant sites. The post-hoc analysis showed that within the non-birth control group, the HDR had significantly lower tibial SOS scores of bone strength when compared to the LDR but Aere were no significant differences found between the two dietary restraint groups for those currently on birth control. HDR had significantly lower levels of OC than LDR and the BC group had lower levels of BAP than the nBC group. Consistently, the follow-up analysis revealed that within those not on birth control, subjects who were classified as HDR had significantly (f*<0.05) lower levels of OC when compared with LDR but no significant differences were observed in bone turnover between the two dietary restraint groups for those currently on birth control. Physical activity was not correlated with SOS scores and bone turnover markers possibly due to the low physical activity variability in this group of women. Conclusion This is the first study to examine the effects of dietary restraint on bone strength and turnover among this population of women. The most important finding of this study was that bone strength and turnover are negatively influenced by dietary restraint independent of relative body fat. In general, the results of the present thesis suggest that dietary restraint, oral contraceptive use, as well as low daily calcium intake and low physical activity levels were widespread behaviours among this population of college-aged women. The young women who were using dietary restraint as a strategy to lose weight, and thus were in the HDR group, despite their higher relative body fat and weight, had lower scores of bone strength and lower levels of markers of bone turnover compared to the low dietary restrainers. Additionally, bone turnover seemed to be negatively affected by oral contraceptives, while bone strength, as assessed by QUS, seemed unaffected by their use in this population of young women. Physical activity (weekly energy expenditure), on the other hand, was not associated with either bone strength or bone tiimover possibly due to the low variability of this variable in this population of young Canadian women.

Home bias no mercado de capitais brasileiro : um estudo sobre a custódia de investidores em ações

A presente dissertação apresenta uma análise da concentração do portfólio de a-ções de investidores brasileiros nas próprias empresas onde trabalham com o intuito de observar se o Home Bias se aplica à amostra analisada. Nosso estudo foi reali-zado com uma amostra extraída da custódia de 86 clientes de uma corretora de va-lores mobiliários, sendo estes dados reais de mercado. Restringimos a seleção da amostra de forma que metade fosse de clientes que trabalham em empresas de ca-pital aberto e a outra metade não. Foi feita análise cross section de quanto os inves-tidores alocam em ações das empresas para a qual trabalham e verificou-se qual o percentual desta participação em seus portfólios, em comparação a uma amostra de controle de investidores que não trabalham nesta mesma empresa. Além destas a-nálises, separamos a amostra pelo valor total do portfólio e realizamos os mesmos estudos com estes dois grupos diferentes da amostra. Como uma análise de robus-tez, identificamos empresas listadas que não adotam a remuneração com ações como uma sub-amostra do estudo. Como resultado, encontramos evidências de que os funcionários investem significativamente mais (seja em proporção do portfólio ou em valores) em ações das empresas onde trabalham em relação aos demais inves-tidores, evidenciando um viés de familiaridade na tomada de decisão de investimen-tos.

Conhecimento sobre energia eólica: um estudo exploratório a partir das redes semânticas naturais de estudantes da cidade de Natal

The human being has a fundamental role in issues concerning scarcity of energy resources as well as in the success of technologies which favor the use of renewable sources, such as wind energy. But what does wind energy mean for people? What are the psychological meanings concerning this term? Aiming to answer these questions, the general objective of this dissertation was to identify and to analyze the knowledge about wind energy taking into account a network of psychological meanings. One hundred and ninety one (191) university students from Natal-RN participated in the study, being male the majority (53%); aged between 17 and 51 years old (M=23.3 years; SD=5.7). Participants responded to self reports using the Natural Semantic Networks (NSW) technique, as well as to several sociodemographic questions. The results showed a consistent, positive and useful general semantic network. In this semantic network, knowledge about wind energy was represented by words that correspond to the appeal of (pro) environmental stance (e.g., clean and nature), that evinced both the technological aspect (e.g., force) and the economic aspect (e.g., economy). Results from different groups were also analyzed. The first set of groups (non-environemental and environmental) was divided considering the course (e.g., ecology and economy). The second set of groups(non-caretaker and caretaker) was divided based on the practice of environmental care expressed. Subtle differences were observed in the semantic networks of caretakers, who emphasized environment, an attribute not mentioned by non-caretakes. This indicates a construction of knowledge that is influenced by the presence or absence of the environmental commitment. Such findings may be useful in the construction of instruments for surveys and in the development of public and educational policies. Additionally, they may assist the media towards a more objective performance concerning wind energy

Permutation-based stochastic ordering using pairwise comparisons

The topic of this work concerns nonparametric permutation-based methods aiming to find a ranking (stochastic ordering) of a given set of groups (populations), gathering together information from multiple variables under more than one experimental designs. The problem of ranking populations arises in several fields of science from the need of comparing G>2 given groups or treatments when the main goal is to find an order while taking into account several aspects. As it can be imagined, this problem is not only of theoretical interest but it also has a recognised relevance in several fields, such as industrial experiments or behavioural sciences, and this is reflected by the vast literature on the topic, although sometimes the problem is associated with different keywords such as: "stochastic ordering", "ranking", "construction of composite indices" etc., or even "ranking probabilities" outside of the strictly-speaking statistical literature. The properties of the proposed method are empirically evaluated by means of an extensive simulation study, where several aspects of interest are let to vary within a reasonable practical range. These aspects comprise: sample size, number of variables, number of groups, and distribution of noise/error. The flexibility of the approach lies mainly in the several available choices for the test-statistic and in the different types of experimental design that can be analysed. This render the method able to be tailored to the specific problem and the to nature of the data at hand. To perform the analyses an R package called SOUP (Stochastic Ordering Using Permutations) has been written and it is available on CRAN.

Assessing homogeneity in workplace exposure under stationary and non-stationary scenarios

In most epidemiological studies, historical monitoring data are scant and must be pooled to identify occupational groups with homogeneous exposures. Homogeneity of exposure is generally assessed in a group of workers who share a common job title or work in a common area. While published results suggest that the degree of homogeneity varies widely across job groups, less is known whether such variation differs across industrial sectors, classes of contaminants, or in the methods used to group workers. Relying upon a compilation of results presented in the literature, patterns of homogeneity among nearly 500 occupational groups of workers were evaluated on the basis of type of industry and agent. Additionally, effects of the characteristics of the sampling strategy on estimated indicators of homogeneity of exposure were assessed. ^ Exposure profiles for occupational groups of workers have typically been assessed under the assumption of stationarity, i.e., the mean exposure level and variance of the distribution that describes the underlying population of exposures are constant over time. Yet, the literature has shown that occupational exposures have declined in the last decades. This renders traditional methods for the description of exposure profiles inadequate. Thus, work was needed to develop appropriate methods to assess homogeneity for groups of workers whose exposures have changed over time. A study was carried out applying mixed effects models with a term for temporal trend to appropriately describe exposure profiles of groups of workers in the nickel-producing industry over a 20-year period. Using a sub-set of groups of nickel-exposed workers, another study was conducted to develop and apply a framework to evaluate the assumption of stationarity of the variances in the presence of systematic changes in exposure levels over time. ^
