To understand an individual?s behavior, attitudes, and decisions, it is necessary to learn his/her value priorities. In order to explore the structure and hierarchy of values of future preschool and class teachers we conducted a survey (N = 232). It relies on the famous Schwartz value theory in its refined version, applying his PVQ-57 (Portrait Value Questionnaire). The analysis encompassed reliability analysis, goodness of fit, multidimensional scaling, mean rating and ranking, and t-test. The obtained data fits the theoretical model well, and the location of empirical value types can be predicted by the proposed circumplex, except for universalism and benevolence values, which are located in reverse. Several values adjacent in the model appear combined in the data. The value hierarchy starts with Benevolence (Care and Dependability), Self-direction?Action, Security?Personal, Universalism?Concern, and finishes with Humility, Power?Resources and Dominance.

Integration of Schwartz's value theory and Scheler's concept of value in research on the development of the structure of values during adolescence A proposal is presented in the article of integrating Schwartz's circular model of values (1992, 1994, 2006) with Scheler's concept of values (Brzozowski, 1995). The main research goals were: 1) empirical verification of the attempt to include the values of Scheler into the circle of Schwartz's values; 2) use of the concept and measurement of Scheler's values to describe the development of the value structure during adolescence. Two studies were conducted in a group of 988 persons aged from 15 to 20 years. The Scheler Value Scale of Brzozowski (1995) was used along with the new version of the Schwartz's Portrait Value Questionnaire (Schwartz et al., 2011). In the first study, multidimensional scaling of multitrait-multimathod (MTMM) matrix was carried out, into which were introduced the indexes of Scheler's values and the indexes of Schwartz's value types. In this way, it was demonstrated that it is possible to include Scheler's values in the four higher order values within Schwartz's circle of values. In the second study, it was shown that by using the Schelerian values to analyse the development of the value structure, similar results were obtained to those that were acquired with the aid of instruments intended to measure values in Schwartz's approach. The structure becomes differentiated with age and takes on the shape of a circle.

This research aimed at creating a structural model of the indicators of Educational Leadership for Primary School Principals in Thailand, which is considered to be a theoretical model that has been used to test for coherence with the empirical data collected from a sample group of 580 participants, who were selected from 30,719 Primary School Principals from across the country. To create this theoretical structural model, a study of the suitability of the indicators was carried out so that it could be further used in the selection within the model, as well as in the model’s coherence test with the empirical data and in the investigation of the factor loading. The results of the research were as follows: Firstly, all indicators, which had been applied in the research were selected and were then placed into the theoretical structural model because the average and distribution coefficient values were as set in the criteria. Secondly, the theoretical model is coherent with the empirical data as the values of relative Chi-square, Root Mean Square Error of Approximation, Goodness-of-Fit Index, Adjusted Goodness-of-Fit Index, Comparative Fit Index, and Normed Fit Index were as set in the criteria. Finally, the factor loadings of the key elements, sub-elements, and the indicators were as set in the criteria. This showed that the theoretical model from this research can be beneficial for the research population with construct validity.

In a notable series of articles, Hsu advances theoretical models which are used to graduate 7582 observations of aircraft lateral deviations. The goodness of fit of these models, as judged by the χ2 test, is satisfactory. Hsu's main theoretical model is the Double Double Exponential distribution (DDE), a three parameter model whose probability density function is given byOther model types are also considered, such as the family of exponential power distributions whose probability density is cited by Hsu insection 9. This leads to a four-parameter model, and the fit is (not surprisingly) better even than that of the DDE.

Inverse Lomax Distribution

In this article, we propose and study a new three-parameter distribution, called the odd Fréchet inverse Lomax (OFIL) distribution, derived by combining the odd Fréchet-G family and the inverse Lomax distribution. Since Fréchet is a continuous distribution with wide applicability in extreme value theory, the new model contains these properties as well as the characteristics of the inverse Lomax distribution which make it more flexible and provide a good alternative for some well-known lifetime distributions. We initially present a linear representation of its functions and discussion on density and hazard rate function. Then, we study its various mathematical properties. Different estimation methods are used to estimate parameters of OFIL. The Monte Carlo simulation study is carried out to compare the efficiencies of different methods of estimation. The maximum likelihood estimation (MLE) method is used to estimate the OFIL parameters by considering three practical data applications. We show that the related model is the best in comparisons based on Akaike information criterion (AIC), Bayesian information criterion (BIC), and other goodness-of-fit measures.

Abstract Background and Purpose There is a prevailing belief expressed in the physical therapy literature that values influence behavioral choices. There is, however, meager research on physical therapists' values. A values theory was used to study the organization of physical therapists' basic values and to generate hypotheses about age-related value priority differences. SubjectsParticipants were volunteers from the Wisconsin Physical Therapy Association (N=565). Methods Values importance ratings were gathered using a modified Schwartz Values Survey. Demographic data were obtained with an investigator-developed questionnaire. Analyses included descriptive and nonparametric statistics and nonmetric multidimensional scaling. Results The organizational structure of therapists' values was similar to the theoretical model. Physical therapists rated values associated with benevolence as most important and values associated with power as least important. Three of 7 age-related hypotheses were supported. Discussion and Conclusion The theory adequately explained the organization of physical therapists' values and provided rational explanations for age-based value priority differences. Compared with occupationally heterogeneous samples, the results suggest that physical therapists highly prize values that benefit others and give remarkably little importance to values associated with power.

The researchers build an inventory model for retail stores by validating their economicorder quantity through data driven simulation. This paper created an inventoryoptimization model for a personal care retailing business, to avoid stock out and minimize their holding cost and ordering cost. Simulating a thousand different scenarios, the research come up with an optimal inventory model for the two most sellable products in the store. The t-test reveals that product A has a significantly higher demand than product B. The simulation model validates the optimal order quantity of 59 units, with a reorder point of 25 units for product A. However, the simulation model recommends an optimal order quantity of 37 units and a reorder point of 10 units for product B. The Kolmogorov-Smirnov Goodness of Fit Test reveals the normal distribution of the 30 days inventory for Product A but not for Product B. Confirming that stocks out will unlikely happen for product A but will probably occur for product B. The model confirms EOQ findings of product with relatively high demand but low price but a departure for products with low demand but the high price.Keywords: Operations management, retail inventory system, t-test, Monte Carlo Simulation,Kolmogorov-Smirnov Goodness of Fit Test, Davao City, Philippines, Southeast Asia

Stand Characteristics

This study examined a theoretical model for stand structures from the volumes of pulpwood and saw logs of clear-cut stands. The average stem size was used to estimate the number of cut trees. The distribution was solved using nonlinear derivative-free optimization. The truncated 2-parameter Weibull distribution was used to describe the stand structure of the commercial stems. This method was first tested with harvester data collected from seven clear-cut stands in southern Finland. Validation included reliability in the stand characteristics and goodness-of-fit of the species-specific distributions. The distributions provided unbiased estimates for the saw log volume, while the bias in the estimated pulpwood volume was 2%. The standard stand characteristics from the Weibull distributions corresponded notably well with the harvester data. A Kolmogorov-Smirnov (KS) test rejected two distributions out of 21 cases, when the accurate input variables were available for the theoretical model. The results of the study suggest that the presented method is a relevant option for predicting the stand structure. In practice, the reliability of the presented method was dependent on the quality of the information available from the stand prior to cutting. With a timber trade data set, the solution for the distribution for a clear-cut section was found. The goodness-of-fit was dependent on the accuracy of the visually assessed timber trade variables. Especially the average stem size proved difficult to assess due to high number of understorey pulpwood stems. Due to overestimated average stem sizes, the solved number of harvested trees was underestimated. Less than 50% of the distributions predicted for clear-cut sections passed the KS test.
