First Moment

This paper is devoted to a detailed examination of the exact sampling properties of the instrumental variables (IV) estimator of the vector of coefficients on the exogenous variables in a single structural equation. The first two moments of a linear combination of the elements of this estimator and the joint distribution of these elements are considered. Estimable bounds for the first moment that can readily be incorporated into any IV estimation package are provided. The results obtained are in terms of the same special functions as those that characterize other results for this model, allowing a unified treatment of the model.

This paper examines the exact sampling behavior of a family of instrumental variables estimators of the coefficients in a single structural equation when the model has been misspecified by the incorrect inclusion or exclusion of variables. It is found that such specification errors can have implications for the structure of the exact results obtained. A brief numerical examination of the analytical results is also provided.

Finite Sample Properties

Exact expressions are derived for the density function, variance, and kurtosis of a linear combination of the elements of a two-stage estimator for the coefficients in a single equation of a SUR system. The estimator is the first iterate in the iterative generalized least squares procedure described by Telser [14]. Our results generalize all previously known results for this estimator and, in certain special cases, also generalize some earlier exact results for Zellner's unrestricted covariance matrix estimator, to which it reduces in these special cases.

This study aims to analyze and prove the Influence Career Development, Work Environment, Compensation and it’s implication on job satisfaction of permanent lecturer of maritime colleges in DKI Jakarta both partially and simultaneously. The research method used is descriptive survey method and explanatory survey with 253 respondents. The analysis of the data used is Structural Equation Modeling (SEM), consisting of career development, work environment and compensation as exogenous variables, job satisfaction as an endogenous variable. Based on the partially and simultaneous research that Career development, work environment and compensation have a positive and significant effect on job satisfaction with a contribution (R2) of 92 %. Work environment has the most dominantt effect on the job satisfaction of lecturers at maritime colleges in DKI Jakarta.

<p align="center"> </p><p>Workload, problem management and task completion in forestry are the work entrusted to the Forestry Extension Workers. In the highly complex condition of forestry problems, Forestry Extension Workers are needed to bridge and outline the problems and to prevent the emergence of deeper, more widespread and prolonged problems. The problems served as the background for the writer to conduct the study in the thesis completion in the Master of Management Program.  The problems are related to the effects of competence, compensation and career development factors of the Forestry Extension Workers working in the Ministry of Environment and Forestry and the performance expected to achieve the completion of forestry extension works. The data analysis used to explain the effects of competence, compensation and career development and the performance of Forestry Extension Workers was the Structural Equation Model (SEM) with Smart PLS. Based on the estimations and t-values, it can be concluded that the exogenous variables of compensation and career development affect the endogenous latent factor of the performance of Forestry Extension workers (?), whereas competence has no effect on the performance of Forestry Extension Workers.</p><p> </p>

Abstract The Salem problem to verify whether Fourier–Stieltjes coefficients of the Minkowski question mark function vanish at infinity is solved recently affirmatively. In this paper by using methods of classical analysis and special functions we solve a Salem-type problem about the behavior at infinity of a linear combination of the Fourier–Stieltjes transforms. Moreover, as a consequence of the Salem problem, some asymptotic relations at infinity for the Fourier–Stieltjes coefficients of a power {m\in\mathbb{N}} of the Minkowski question mark function are derived.

Perceived Impact

PurposeThe purpose of this paper is to examine the perceived impact of outsourcing on customer service management.Design/methodology/approachThe examination was conducted via a survey on 124 companies in Malaysia. Using the framework from Elmuti, factors manifesting customer service management were regressed on the key factors manifesting successful outsourcing. Hence a model was contrived. Structural equation modelling (SEM) was used to estimate the model.FindingsThe model was able to provide predictive implications on customer service management, given the activities of key factors manifesting successful outsourcing. In other words to improve customer service management, companies could control their outsourcing activities.Originality/valueThis paper offers an approach to measure the effects of multiple independent variables on multiple dependent variables. Using SEM, multivariate analyses were mathematically represented in a single equation. In this equation, companies could holistically compose strategies to optimise their management in customer service.
