Do personality factors predict job satisfaction?

Two studies investigated the relationships between personality traits and aspects of job satisfaction. In Study 1, job applicants (n=250) completed the Eysenck Personality Profiler and the Work Values Questionnaire (WVQ), which requires respondents to rate various work-related facets according to the extent to which they contribute to their job satisfaction. These facets were combined into two composites (hygiene and motivator) based on previous research. The three personality superfactors accounted for a small percentage of the variance in importance ratings (about 5%). In Study 2, employees (n=82) completed a measure of the 'Big Five' personality traits and the Job Satisfaction Questionnaire (JSQ), which assesses both what respondents consider as important in their work environment as well as their satisfaction with their current job. Importance ratings were again combined into two composites while job satisfaction ratings were factor analyzed and three factors, differentiated along hygiene versus motivator lines, emerged. Personality traits again accounted for a small percentage of the total variance both in importance ratings and in levels of job satisfaction. It is concluded that personality does not have a strong or consistent influence either on what individuals perceive as important in their work environment or on their levels of job satisfaction.

Foucault’s Perspective of Performance Appraisal in Public Administration

The main purpose of performance appraisal in organizations is, or should be, to improve the engagement, learning process and progress of the employees and to align individual with team and organizational performance. However, performance appraisal can also be interpreted as an instrument of normalization, discipline and surveillance. This study thus aims to explore and discuss the complex schema of intrinsic and extrinsic objectives of performance appraisal system of the Portuguese public organizations (SIADAP - Performance Evaluation Integrated System). We have developed an exploratory and qualitative case study to capture appraisers and appraises perceptions. The data were analyzed in light of foucauldian theories. According to the qualitative data, namely the discourses of the appraisers and their subordinates, the SIADAP is seen as an instrument of control and dominance that aims to introduce political rationalities, limiting the career progression of the employees. Though some key points of Foucault’s perspective were identified, foucauldian framework revealed some limitations to capture all the complexity inherent to performance appraisal. This study opens new perspectives about the SIADAP and can be of major importance as far as political reflection about performance appraisal in public organizations is concerned.

Motivação e percepção do envolvimento parental na prática desportiva de jovens nadadores

RESUMO: O envolvimento parental no desporto é determinante no processo de formação desportiva dos jovens desportistas. Pelo facto de existirem poucos instrumentos de avaliação neste assunto, a adaptação e validação do Parental Involvement Sport Questionnaire (PISQ) para o idioma Português, tornou-se fundamental para colmatar esta lacuna. Assim, o presente estudo pretende alcançar dois objectivos principais: a) traduzir e adaptar o PISQ ao idioma Português do Brasil e, deste modo, iniciar o processo de validação do referido instrumento; b) analisar a relação entre a percepção dos jovens sobre o envolvimento parental na sua prática de natação e a motivação destes jovens nadadores. Um total de 114 nadadores participaram deste estudo, com idades compreendidas entre os 12 e 20 anos [ M = 14.67; DP = 8.29], para aferir utilizamos a versão Portuguesa do PISQ e do Sport Motivation Scale (SMS). Como principais resultados, a versão portuguesa do PISQ apresentou um Alpha de Cronbach deos comportamentos directivos dos pais mostraram reduzir a motivação intrínsica – saber, a motivação intrínsica pela prática e a motivação extrínsica – introjectada, e aumentar a amotivação dos jovens desportistas. ABSTRACT: The parental involvement in sport is crucial in the process of sports training of young athletes and, because there are few instruments for assessing this issue, the adaptation and validation of the Parental Involvement Sport Questionnaire (PISQ) for the Portuguese language, it became essential to bridge this gap. Thus, this study aims to achieve two main objectives: a) translate and adapt the PISQ to the Portuguese language of Brazil and thus begin the process of validation of that instrument, b) analyze the relationship between the perception of young people about the involvement parental in their practice of swimming, and the motivation of these young swimmers. A total of 114 swimmers participated in this study, aged between 12 and 20 years [M = 14.67, SD = 8.29], we used to measure the Portuguese version of PISQ and the Sport Motivation Scale (SMS). As main results, the Portuguese version of PISQ showed a Cronbach’s Alpha of , directive behaviors of the parents shown to reduce intrinsic and extrinsic motivation, and increase the amotivation of the young athletes.

Motivations which influence volunteers' satisfaction

In this paper we attempt to find out which motivations influence volunteers satisfaction. So, in a first moment, we categorize satisfaction through a factor analysis and then use linear regression models to find out the relations previously mentioned. Furthermore we analyse the existence of correlations between some demographic attributes and the other variables. In this research the population under study includes volunteers that work in the health area, more precisely volunteers that work in hospital and have direct contact with patients and their families. We obtained a total of 327 questionnaires and after excluding incomplete answers we get 304 questionnaires which embody a response rate of 36%. The outcomes of our analysis reveal that we can categorize satisfaction into intrinsic and extrinsic categories and show that motivations related to belonging and protection and career recognition are the ones influencing extrinsic satisfaction; motivations associated to development and learning and altruism are the ones with higher effect in intrinsic satisfaction. There are some negative correlations between age and extrinsic satisfaction, between years of participation and extrinsic satisfaction, between education and the motivation related to belonging and protection and between age and the motivation related to career recognition. There is only one positive correlation between hours per week and intrinsic satisfaction. The results offer new insights for research about volunteers’ motivations, motive fulfillment and volunteer satisfaction. Furthermore the outcomes advocate that to ensure satisfied volunteers, their motivations must be identified in a timely and appropriate moment, meaning that should happened as early as possible.

Sistema de visão e laser para percepção em ambientes subaquáticos

A exploração do meio subaquático utilizando visão computacional é ainda um processo complexo. Geralmente são utilizados sistemas de visão baseados em visão stereo, no entanto, esta abordagem apresenta limitações, é pouco precisa e é exigente em termos computacionais quando o meio de operação é o subaquático. Estas limitações surgem principalmente em dois cenários de aplicação: quando existe escassez de iluminação e em operações junto a infraestruturas subaquáticas. Consequentemente, a solução reside na utilização de fontes de informação sensorial alternativas ou complementares ao sistema de visão computacional. Neste trabalho propõe-se o desenvolvimento de um sistema de percepção subaquático que combina uma câmara e um projetor laser de um feixe em linha, onde o projetor de luz estruturada _e utilizado como fonte de informação. Em qualquer sistema de visão computacional, e ainda mais relevante em sistemas baseados em triangulação, a sua correta calibração toma um papel fulcral para a qualidade das medidas obtidas com o sistema. A calibração do sistema de visão laser foi dividida em duas etapas. A primeira etapa diz respeito à calibração da câmara, onde são definidos os parâmetros intrínsecos e os parâmetros extrínsecos relativos a este sensor. A segunda etapa define a relação entre a câmara e o laser, sendo esta etapa necessária para a obtenção de imagens tridimensionais. Assim, um dos principais desafios desta dissertação passou por resolver o problema da calibração inerente a este sistema. Desse modo, foi desenvolvida uma ferramenta que requer, pelo menos duas fotos do padrão de xadrez, com perspectivas diferentes. O método proposto foi caracterizado e validado em ambientes secos e subaquáticos. Os resultados obtidos mostram que o sistema _e preciso e os valores de profundidade obtidos apresentam um erro significativamente baixo (inferiores a 1 mm), mesmo com uma base-line (distância entre a centro óptico da câmara e o plano de incidência do laser) reduzida.

Imaging the Hypoglossal Nerve

The hypoglossal nerve is a pure motor nerve. It provides motor control to the intrinsic and extrinsic tongue muscles thus being essential for normal tongue movement and coordination. In order to design a useful imaging approach and a working differential diagnosis in cases of hypoglossal nerve damage one has to have a good knowledge of the normal anatomy of the nerve trunk and its main branches. A successful imaging evaluation to hypoglossal diseases always requires high resolution studies due to the small size of the structures being studied. MRI is the preferred modality to directly visualize the nerve, while CT is superior in displaying the bony anatomy of the neurovascular foramina of the skull base. Also, while CT is only able to detect nerve pathology by indirect signs, such as bony expansion of the hypoglossal canal, MRI is able to visualize directly the causative pathological process as in the case of small tumors, or infectious/inflammatory processes affecting the nerve. The easiest way to approach the study of the hypoglossal nerve is to divide it in its main segments: intra-axial, cisternal, skull base and extracranial segment, tailoring the imaging technique to each anatomical area while bearing in mind the main disease entities affecting each segment.

Fatores individuais de risco de infeção hospitalar : conhecer para prevenir

RESUMO - Medidas efetivas de prevenção e controlo de infeção, assim como a sua aplicação diária e consistente, devem fazer parte da cultura de segurança dos profissionais de saúde para promover a excelência da prestação de cuidados. Também a identificação dos fatores de riscos individuais de infeção é crucial e indispensável para a adoção de medidas para a gestão desses mesmos riscos. A avaliação do risco pretende determinar a probabilidade que um doente tem de adquirir ou disseminar uma infeção hospitalar (IH) (WIRRAL, 2008) nas unidades de saúde. A avaliação deve ser efetuada na admissão do doente e, de forma periódica durante o internamento, usando uma grelha de avaliação, integrada no processo global de cuidados do doente. Efetuada a avaliação de risco individual, que pressupõe a identificação dos fatores de risco do doente (fatores de risco intrínsecos e extrínsecos) pode ser implementado um plano de cuidados individualizado para os gerir. Pretendeu-se com este estudo identificar os fatores de risco de infeção hospitalar do doente que estão presentes na admissão e/ou que podem surgir durante o seu internamento, para que posteriormente seja possível determinar as medidas de prevenção (gestão do risco) a aplicar individualmente. Foi realizado um estudo de caso-controlo com os doentes internados no Hospital dos Lusíadas em 2011 com o objetivo de, por um lado, determinar os fatores de risco individuais que contribuem para a aquisição da IH e, por outro, caraterizar os fatores de risco para uma futura identificação de possíveis medidas de prevenção e controlo da aquisição e transmissão cruzada da infeção hospitalar. A população em estudo foi constituída pelos doentes que foram internados, entre 1 de Janeiro e 31 de Dezembro de 2011 sendo os casos os doentes em que foi identificada a presença de infeção hospitalar através do programa institucional de vigilância epidemiológica das infeções, tendo os controlos sido selecionados numa razão de 3:1 caso. Foi utilizado um suporte estruturado para a colheita de dados, com a listagem de fatores de risco identificados na revisão bibliográfica e de todos os fatores de risco apresentados pelos doentes em estudo. Os fatores de risco identificados que apresentaram um maior significado estatístico foram: a idade acima dos 50 anos, o género masculino, a administração de antimicrobianos nas três semanas anteriores ao internamento, a colocação de cateter venoso central, a algaliação e, no caso dos doentes cirúrgicos, a cirurgia de urgência e a classificação ASA 3. Após a identificação dos fatores de risco da população estudada neste hospital, é agora possível utilizar a informação obtida e delinear investigações adicionais, objetivando a construção de instrumentos para a identificação de doentes com risco aumentado de infeção.

Measuring university-to-work success: development of a new scale

Purpose – The purpose of this paper is to develop a subjective multidimensional measure of early career success during university-to-work transition. Design/methodology/approach – The construct of university-to-work success (UWS) was defined in terms of intrinsic and extrinsic career outcomes, and a three-stage study was conducted to create a new scale. Findings – A preliminary set of items was developed and tested by judges. Results showed the items had good content validity. Factor analyses indicated a four-factor structure and a second-order model with subscales to assess: career insertion and satisfaction, confidence in career future, income and financial independence, and adaptation to work. Third, the authors sought to confirm the hypothesized model examining the comparative fit of the scale and two alternative models. Results showed that fits for both the first- and second-order models were acceptable. Research limitations/implications – The proposed model has sound psychometric qualities, although the validated version of the scale was not able to incorporate all constructs envisaged by the initial theoretical model. Results indicated some direction for further refinement. Practical implications – The scale could be used as a tool for self-assessment or as an outcome measure to assess the efficacy of university-to-work programs in applied settings. Originality/value – This study provides a useful single measure to assess early career success during the university-to-work transition, and might facilitate testing of causal models which could help identify factors relevant for successful transition.

Diffusion spectrum imaging shows the structural basis of functional cerebellar circuits in the human cerebellum in vivo.

BACKGROUND: The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits. Identifying the structural bases of cerebellar neuronal networks in humans in vivo may provide biomarkers for diagnosis and management of cerebellar diseases. OBJECTIVES: To define the anatomy of intrinsic and extrinsic cerebellar circuits using high-angular resolution diffusion spectrum imaging (DSI). METHODS: We acquired high-resolution structural MRI and DSI of the cerebellum in four healthy female subjects at 3T. DSI tractography based on a streamline algorithm was performed to identify the circuits connecting the cerebellar cortex with the deep cerebellar nuclei, selected brainstem nuclei, and the thalamus. RESULTS: Using in-vivo DSI in humans we were able to demonstrate the structure of the following cerebellar neuronal circuits: (1) connections of the inferior olivary nucleus with the cerebellar cortex, and with the deep cerebellar nuclei (2) connections between the cerebellar cortex and the deep cerebellar nuclei, (3) connections of the deep cerebellar nuclei conveyed in the superior (SCP), middle (MCP) and inferior (ICP) cerebellar peduncles, (4) complex intersections of fibers in the SCP, MCP and ICP, and (5) connections between the deep cerebellar nuclei and the red nucleus and the thalamus. CONCLUSION: For the first time, we show that DSI tractography in humans in vivo is capable of revealing the structural bases of complex cerebellar networks. DSI thus appears to be a promising imaging method for characterizing anatomical disruptions that occur in cerebellar diseases, and for monitoring response to therapeutic interventions.

Calibration of a Structured Light-Based Stereo Catadioptric Sensor

Catadioptric sensors are combinations of mirrors and lenses made in order to obtain a wide field of view. In this paper we propose a new sensor that has omnidirectional viewing ability and it also provides depth information about the nearby surrounding. The sensor is based on a conventional camera coupled with a laser emitter and two hyperbolic mirrors. Mathematical formulation and precise specifications of the intrinsic and extrinsic parameters of the sensor are discussed. Our approach overcomes limitations of the existing omni-directional sensors and eventually leads to reduced costs of production

La perception de la productivité dans l'industrie hôtelière de luxe : le cas de la Suisse romande

La perception de la productivité SUMMARY The main objective of this thesis is the perception of the productivity in the luxury hospitality industry. Despite a lot of efforts which were already made in the field of the production of goods, this concept (productivity) still remains to be defined in the services sector, more still, in that of the luxury hospitality industry. Since the object of this study is the perception of productivity, we decided to analyze the elements considered to be relevant by the top management in this field. Then, it seemed important to evaluate these same elements for the categories of middle-management and by the in-line employees. As perception is not static, it is dependent in an indirect way on its improvement and however also with the means of improvement. The assumption of our work evokes the possible relationship between productivity and its perception (P), (Q) quality and profitability (R). On this basis we built the P-Q-R model: R=F(P,Q) Finally, our research on this model enabled us to establish a mathematical relation between the three predetermined elements: fR=fP+fQ+c That means that the function efficiency of a process of services -(fR) is the sum of its quality function (intrinsic and extrinsic)-(fP) and of its productivity function - fQ (and the constant of regression "c"). To increase the profitability of the most significant manner, it is necessary to increase at the same time the productivity and quality. On the other hand, according to this formula but also according to the perception of the managers, with a constant profitability, either the productivity decreases in favor of the increase in quality, or the reverse. If the dimensions of the model influence positively or negatively the production process of services, then those wí11 influence in same manner our model (P, Q, R). We advance a point of view saying that profitability depends on the labor productivity which follows same dynamics than the perception of the productivity. The identification of the labor productivity as an essential element of successful management of the hotel is fundamental. The question which always remains in suspense is however the relevance of the concept "labor productivity" for the luxury hospitality industry. It was not proven an obvious correlation between this notion and the one of profitability. We still remain at the stage of perception. It results that one interesting way of future research will be the study of this correlation. As in any kind of luxury industry, the real added value does not consist in the volume produced or in the speed with which the product/service is carried out but in the creativity involved in their results. Let us note that the field of luxury is extremely related to the emotions and to the experience provided to the customers. La perception de la productivité... RÉSUME L'objectif principal de cette thèse est la perception de la productivité dans l'hôtellerie de luxe. Malgré tous les efforts qui ont déjà été faits dans le domaine de la production de biens, ce concept (productivité) reste encore à définir dans le secteur des services, plus encore, dans celui de l'hôtellerie de luxe. Étant donné que l'objet de l'étude est la perception de la productivité, nous avons décidé d'analyser les éléments jugés pertinents par les cadres dirigeants dans ce domaine. Puis, il nous a semblé important d'évaluer ces mêmes éléments pour les catégories de cadres moyens et par les employés in-line. Comme la perception n'est pas statique, elle est liée d'une manière indirecte à son amélioration et cependant également aux moyens d'amélioration. L'hypothèse de notre travail évoque la possible relation entre la productivité et sa perception (P), la qualité (Q) et la rentabilité (R). Sur cette base nous avons construit le modèle P-Q-R de départ R=f(P,Q) Finalement, notre recherche sur ce modèle nous a permis d'établir une relation mathématique entre les trois construits prédéterminés: fR=fP+fQ+c Cela signifie que la fonction rentabilité d'un processus de services -(fR) est la somme de sa fonction qualité (intrinsèque et extrinsèque)-fP et de sa fonction productivité -fQ (plus la constante de régression « c ») Pour augmenter la rentabilité de la manière la plus significative, il faut augmenter en même temps la productivité et la qualité. En revanche, selon cette formule mais selon aussi la perception des managers, à une rentabilité constante, soit la productivité diminue en faveur de l'augmentation de la qualité, soit l'inverse. Si les dimensions du modèle influencent positivement ou négativement le processus de production de services, alors celles-ci vont influencer de la même manière les construits de notre modèle (P, Q, R). Nous avançons un point de vue disant que la rentabilité dépend de la productivité du travail qui suit la même dynamique que la perception de la productivité. L'identification de la productivité du travail comme élément essentiel de gestion réussie de l'hôtel s'avère fondamentale. La question qui reste toujours en suspens est pourtant la pertinence de la notion «productivité du travail » pour l'industrie hôtelière de luxe. Il n'a pas été prouvé une corrélation évidente entre cette notion et celle de la profitabilité. Nous restons donc ici encore au stade de perception. Il en résulte que l'une des voies les plus intéressantes de recherche future sera l'étude de cette corrélation. Comme dans toute industrie de luxe, la vraie valeur ajoutée ne consiste pas toujours dans le volume produit, ni dans la vitesse avec laquelle le produit/service est réalisé, mais parfois dans la créativité emmagasinée dans ces résultats. Notons que le domaine de luxe est extrêmement lié aux émotions et à l'expérience fournie aux clients.

Tabela de vida de fertilidade de Lysiphlebus testaceipes (Cresson, 1880) (Hymenoptera, Aphidiidae) em Schizaphis graminum (Rondani, 1852) (Hemipera, Aphididae)

Life table analyses have been developed to understanding the impact of various sources of intrinsic and extrinsic mortalities on the rate of population growth. The understanding of the population increase of the parasitoids related to their hosts is important in biological control programs. This work had as objective to evaluate the survival and fertility of the parasitoid Lysiphlebus testaceipes (Cresson, 1880) on Schizaphis graminum (Rondani, 1852) as a host under fertility life table. The experiment were carried out in a climatic chamber at 25 ± 1ºC, RH 60 ± 10% and 10h photophase. To determine the immature mortality, the development time and the sex ratio of the parasitoid, 12 females of the parasitoid (less than one day old) and 240 nymphs of S. graminum (3 days old) were used. To evaluate the longevity and fertility of L. testaceipes, 15 females (less than one day old) were used. Nymphs of S. graminum (3 days old) were offered for each parasitoid female daily, until the female died, being in the 1st day - 300 nymphs; 2nd day - 250 nymphs; 3rd day - 200 nymphs; 4th day - 150 and in the other days a number of 50 nymphs. L. testaceipes had an immature mortality of 22,2%, and a development time of males and females of 9.0 and 9.1 days, respectively. The females of L. testaceipes laid, in it first life day, 257.8 eggs, and they survived up until seven days. The net reproduction rate (Ro) and the intrinsic rate of increase (r m) were respectively, 301.9 and 0.513. The finite rate of increase (l) was 1.67 females per day, the mean length of a generation (T) was 11.13 days and the time to duplicate the population (TD) was 1.35 weeks. The parasitoid L. testaceipes have a high potential of population growth on S. graminum as a host under the analyzed conditions.
