Feeling Good about Giving: The Benefits (and Costs) of Self-Interested Charitable Behavior
In knowledge-intensive settings such as product or software development, fluid teams of individuals with different sets of experience are tasked with projects that are critical to the success of their organizations. Although building teams from individuals with diverse prior experience is increasingly necessary, prior work examining the relationship between experience and performance fails to find a consistent effect of diversity in experience on performance. The problem is that diversity in experience improves a team's information processing capacity and knowledge base, but also creates coordination challenges. We hypothesize that team familiarity - team members' prior experience working with one another - is one mechanism that helps teams leverage the benefits of diversity in team member experience by alleviating coordination problems that diversity creates. We use detailed project- and individual-level data from an Indian software services firm to examine the effects of team familiarity and diversity in experience on performance for software development projects. We find the interaction of team familiarity and diversity in experience has a complementary effect on a project being delivered on time and on budget. In team familiarity, we identify one mechanism for capturing the performance benefits of diversity in experience and provide insight into how the management of experience accumulation affects team performance.Diversity, Experience, Knowledge, Software, Team Familiarity
Modeling of Malaria Prevalence in Indonesia with Geographically Weighted Regression
Malaria is a public health problem that can lead to death, especially in high-risk groups i.e. infants, toddlers and pregnant women. This disease is still endemic in most parts of Indonesia. The relation of location factor between regions with the surrounding region was assumed to give the effect of spatial variability in the prevalence of malaria in the region. It would lead to the prevalence of malaria modeling using classical regression methods become less precise due to the assumption of homogeneity of variance was not met. It could be overcome by Geographically Weighted Regression (GWR) modeling. In GWR analysis, the selection weighting function was one determinant of the analysis results. GWR analysis resulted on the prevalence of malaria in Indonesia, GWR model with bisquare kernel weighting function had a better value of R2 and AIC than GWR models with gaussian kernel weighting function
Estimation of Percentage on Malnutrition Occurrences in East Java Using Geographically Weighted Regression Model
The Province of East Java has its own characteristics that differentiate it from any other regions. Dissimilarities in characteristics of a region may encompass issues such as social, economic, cultural, parenting, education, and the environment, so as to cause the difference in case of severe under nutrition between one region to another. Sufferers of malnutrition in one region may be linked and influenced by the surrounding regions. Therefore, we need a statistical modeling that is able to take into account the spatial factor. Statistical methods that can be used to analyze the data and also takes into account the spatial factor are the Geographically Weighted Regression (GWR). This study is aimed to determine the case of malnutrition models in East Java Province using GWR model with kernel adaptive bi-square weighting and comparing it to the conventional linear regression model.  The data used in the study are secondary data obtained from the National Socio-Economic Survey and Basic Health Research (2010) conducted in 38 districts in East Java. Estimation is done by using the Weighted Least Squares method that provides different weighting values to each region. The result showed that there are 38 models of the malnutrition case that is different for each district in East Java. The GWR model with bi-square kernel weighting function is better in modelling the case of malnutrition in East Java compared to the conventional linear regression models that are based on the criteria of goodness that is the R-square, Mean Square Error and the Akaike Information Criterion

Cysteine, Malondyaldehide (MDA) and Glutathione (GSH) Levels in Marasmic Type Malnutrition
Micronutrien deficiency in severe malnutrition will reduce antioxidant capacity that needed for oxidative stress defense. Cysteine, a non-essential amino acid, is one of an important component for reduced glutha-tione (GSH). This study aims to prove the difference between the levels of cysteine, MDA and GSH levels in children with marasmic malnutrition and well-nourished children and prove whether there is a relationship between those parameters. Fiftysix patients participated in this study were grouped into two groups of sam-ples that were marasmic type malnutrition group (28 patients) and control groups that were well nourished group (28 patients). Examination begins with a complete laboratory screening, followed by examination of cysteine, MDA and GSH level. Of the 28 patients included in marasmic type malnutrition group consisting of 15 male patients (53.6%) and 13 female patients (46.4%), while the well-nourished group consisted of 13 male patients (46.4%) and 15 female patients (53.6%). The average age is 54.61±56.35 months in the group of ma-rasmic type malnutrition and 48.25±45.34 months in the well-nourished group. By using the Mann Whitney test, there were significant difference between the levels of cysteine and GSH in marasmic malnutrition and control group (p = 0.000 and p = 0.000 respectively). Spearman correlation test between cysteine and GSH levels, cysteine and MDA levels, MDA and GSH levels in marasmic malnutrition children shows no significant correlation (R = -0.206, p = 0.294; R = -0.036, p = 0.856; R = 0.210, p = 0.284 respectively). In well-nourished group Spearman correlation test between cysteine and GSH levels, cysteine and MDA levels, MDA and GSH levels also shows no significant correlation (R = -0.053, p=0.789; R = -0.146, p = 0.458; R = -0.079, p = 0.688 re-spectively). From this study it can be concluded that there are significant differences of the levels of cysteine and GSH between severe malnutrition groups compared with the control one. But this study shows no signif-icant correlation between the levels of cysteine and GSH levels in marasmic type malnutrition and well-nourished children
