A cognitive hierarchy model of behavior in the action commitment game

We apply the cognitive hierarchy model of Camerer et al. (Q J Econ 119(3):861-898, 2004)-where players have different levels of reasoning-to Huck et al. (Games Econ Behav 38:240-264, 2002) discrete version of Hamilton and Slutsky (Games Econ Behav 2:29-46, 1990) action commitment game-a duopoly with endogenous timing of entry. We show that, for an empirically reasonable average number of thinking steps, the model rules out Stackelberg equilibria, generates Cournot outcomes including delay, and outcomes where the first mover commits to a quantity higher than Cournot but lower than Stackelberg leader. We show that a cognitive hierarchy model with quantal responses can explain the most important features of the experimental data on the action commitment game in (2002). In order to gauge the success of the model in fitting the data, we compare it to a noisy Nash model. We find that the cognitive hierarchy model with quantal responses fits the data better than the noisy Nash model.

The social activity of nurse teacher – a part of teacherhood Every nurse teacher must know the current health policy in order to use it in teaching. The conception of the role of health policy in curriculum and the concrete teaching of social activity are quite unclear. The purpose of this study was to describe the social activity of nurse teachers. The data were collected by a structured questionnaire (Paltta 1998) via E-mail. The questionnaire included background factors and nine items for society activities. The respondents were nurse teachers, teachers for emergency nursing, public health nurse and midwifery teachers from all polytechnics in Finland. Response rate was 46 % (n = 342). The data were analysed by using descriptive statistics. The results of this study showed that 36 % of nurse teachers evaluated themselves quite active in society activities and 43 % of them evaluated themselves inactive. 32 % of nurse teachers was member and involved to working in general organisations. 28 % of nurse teachers worked or have been worked in local commission or trustees. Nurse teachers evaluated their knowledge about health policy quite good (mean 3.75, Std 0.99). Their knowledge about education policy was also quite good (mean 3.57, Std 1.04). Nurse teachers updated their knowledge about health policy and education policy by reading professional journals, newspapers, internet and following television and radio. According to results nurse teachers are quite active in society activities even tough almost half of them evaluated themselves quite inactive. Although nurse teachers’ knowledge about health policy was quite good by their opinion, they must update and improve the knowledge. In the future it is important to study how nurse teachers use health policy in their teaching and how nurse students’ participation in society activities can be improved.

Effects of Weight Loss on Adipose Tissue, Liver and Heart Metabolism in Humans

Obesity has become the leading cause of many chronic diseases, such as type 2 diabetes and cardiovascular diseases. The prevalence of obesity is high in developed countries and it is also a major cause of the use of health services. Ectopic fat accumulation in organs may lead to metabolic disturbances, such as insulin resistance.Weight loss with very-low-energy diet is known to be safe and efficient. Weight loss improves whole body insulin sensitivity, but its effects on tissue and organ level in vivo are not well known. The aims of the studies were to investigate possible changes of weight loss in glucose and fatty acid uptake and perfusion and fat distribution at tissue and organ level using positron emission tomography and magnetic resonance imaging and spectroscopy in 34 healthy obese subjects. The results showed that whole-body insulin sensitivity increased after weight loss with very-low-energy diet and this is associated with improved skeletal muscle insulin-stimulated glucose uptake, but not with adipose tissue, liver or heart glucose uptake. Liver insulin resistance decreased after weight loss. Liver and heart free fatty acid uptakes decreased concomitantly with liver and heart triglyceride content. Adipose tissue and myocardial perfusion decreased. In conclusion, enhanced skeletal muscle glucose uptake leads to increase in whole-body insulin sensitivity when glucose uptake is preserved in other organs studied. These findings suggest that lipid accumulation found in the liver and the heart in obese subjects without co-morbidies is in part reversible by reduced free fatty acid uptake after weight loss. Reduced lipid accumulation in organs may improve metabolic disturbances, e.g. decrease liver insulin resistance. Keywords: Obesity, weight loss, very-low-energy diet, adipose tissue metabolism, liver metabolism, heart metabolism, positron emission tomography

Challenges and Means for the Front End Activities of Software Development

The front end of innovation is regarded as one of the most important steps in building new software products or services, and the most significant benefits in software development can be achieved through improvements in the front end activities. Problems in the front end phase have an impact on customer dissatisfaction with delivered software, and on the effectiveness of the entire software development process. When these processes are improved, the likelihood of delivering high quality software and business success increases. This thesis highlights the challenges and problems related to the early phases of software development, and provides new methods and tools for improving performance in the front end activities of software development. The theoretical framework of this study comprises two fields of research. The first section belongs to the field of innovation management, and especially to the management of the early phases of the innovation process, i.e. the front end of innovation. The second section of the framework is closely linked to the processes of software engineering, especially to the early phases of the software development process, i.e. the practice of requirements engineering. Thus, this study extends the theoretical knowledge and discloses the differences and similarities in these two fields of research. In addition, this study opens up a new strand for academic discussion by connecting these research directions. Several qualitative business research methodologies have been utilized in the individual publications to solve the research questions. The theoretical and managerial contribution of the study can be divided into three areas: 1) processes and concepts, 2) challenges and development needs, and 3) means and methods for the front end activities of software development. First, the study discloses the difference and similarities between the concepts of the front end of innovation and requirements engineering, and proposes a new framework for managing the front end of the software innovation process, bringing business and innovation perspectives into software development. Furthermore, the study discloses managerial perceptions of the similarities and differences in the concept of the front end of innovation between the software industry and the traditional industrial sector. Second, the study highlights the challenges and development needs in the front end phase of software development, especially challenges in communication, such as linguistic problems, ineffective communication channels, a communication gap between users/customers and software developers, and participation of multiple persons in software development. Third, the study proposes new group methods for improving the front end activities of software development, especially customer need assessment, and the elicitation of software requirements.

Danos na produção da abobrinha de moita causados pelo Papaya ringspot virus type W e Zucchini yellow mosaic virus

Este trabalho teve por objetivo avaliar, em condições de casa de vegetação e de campo, os danos causados pelo PRSV-W e ZYMV em abobrinha-de-moita (Cucurbita pepo cv. Caserta). As plantas em casa de vegetação foram inoculadas com os vírus individualmente e em mistura aos 12 e 22 dias após emergência (DAE) e aos 5, 15 e 25 DAE no campo. Em casa de vegetação, as infecções com PRSV-W + ZYMV, PRSV-W e ZYMV, na primeira época de inoculação, ocasionaram reduções de área foliar de 39,6%, 36,8% e 12,1%, respectivamente. As massas fresca e seca também foram significativamente afetadas na primeira época de inoculação. No campo, as plantas com infecções individuais ou mistas dos potyvírus produziram frutos não comerciais em quantidades que variaram de 14 a 861 g/planta, dependendo da idade que foram inoculadas. As plantas tratadas com tampão fosfato aos 5, 15 e 25 DAE produziram em média 573 g, 937 g e 1172 g de frutos comerciais e 282 g, 221 g e 192 g de frutos não comerciais, respectivamente. A redução na massa fresca das plantas foi diretamente relacionada com a época de inoculação, com médias de 60,7% para aquelas inoculadas aos 5 DAE e de 22,7% para aquelas inoculadas aos 15 DAE. Na terceira época de inoculação não houve diferença significativa de massa fresca entre os tratamentos.

Hipertensão portal esquistossomótica avaliação do fluxo sangüíneo portal antes e após tratamento cirúrgico

OBJETIVO: Avaliar o fluxo sangüíneo portal na esquistossomose hepato-esplênica e o efeito tardio do tratamento cirúrgico na hemodinâmica portal. MÉTODO: Foram estudados 64 pacientes por Doppler dúplex: grupo I (pacientes com hipertensão portal esquistossomótica); grupo II (pacientes submetidos a desconexão ázigo-portal com esplenectomia) e grupo III (pacientes submetidos derivação esplenorrenal distal). RESULTADOS: O fluxo da veia porta foi maior no grupo I (1954,46 ± 693,73ml/min) e foi menor no grupo III (639,55 ± 285,86ml/min), neste correlacionou-se com o tempo pós-operatório (r=-0,67, p=0,0005). O fluxo sangüíneo portal do grupo II (1097,18 ± 342,12ml/min) foi semelhante ao de indivíduos normais. As mesmas alterações foram verificadas com relação ao diâmetro da veia porta nos grupos I, II, e III (cm): 1,46 ± 0,23; 1,12 ± 0,22; 0,93 ± 0,20, respectivamente. CONCLUSÕES: Estes dados sugerem que: 1) Existe hiperfluxo portal na fisiopatologia da hipertensão portal esquistossomótica; 2) o tratamento cirúrgico interferiu na hemodinâmica portal, diminuindo o fluxo sangüíneo da veia porta; 3) Esta redução do fluxo sangüíneo portal correlacionou-se com o tempo de seguimento pós-operatório no grupo III mas não no grupo II.
