An Analysis of Water Treatment Process by the on-line Measurements on Water and Sludge Streams (Published)
Water environmental control and process refinement inside a wastewater treatment plant (WWTP) is fundamentally based on sampling, analysis and on-line measurements on water and sludge streams. The problems related to an accurate and reliable control and thus an efficient water protection are addressed in the following. Four different crucial points whenever a sampling and control scheme is planned: 1) where should a sampling and on-line measurement take place? 2) When should sampling take place? 3) How should the sampling and on-line measurement take place? 4) Which variables should be controlled? Examples are given from different plants demonstrating ways to address the questions. Especially the relevance of the adopted parameter BOD (Biochemical Oxygen Demand) is discussed. It is finally suggested to even abandon the use of BOD as consent variable in favour of on-line measurement of Suspended Solids, Nitrogen and Phosphorous.
Competitive behavior questionnaire is an instrument that is used to determine how strongly individu competes in achieving certain superior targets. Competitive behavior is a behavior to achieve a superior position with respect to the personal targets to be addressed (Gracia, Tor & Schff, 2013). Theory of competitive behavior is developed from Cognitive Social theory, as a result of individual interaction, with its environment (Bandura, 1986). One form of competitive behavior is survival in studying at the level of undergraduate education. However, this competitive behavior has not been widely studied. Therefore, instrument that can be used as a tool is needed to find out appropriate competitive behavior of individuals. In this study, a competitive behavior questionnaire was prepared based on aspects of the drive to compete, the desire to achieve superior positions and self-representation. In total there are 14 aitems with validity score more than 0.30. The reliability score was 0.81.
Integrating HR Measurements into Business Performance: The Role of HR in Enhancing Business Growth (Published)
Integrating HR into business performance measurement system involves identifying the areas of HR deliverables and its linkage to the organization’s strategic plan. The HR deliverables which supports the implementation of the firm’s strategy must be clearly outlined and communicated to all staff to serve as the blue print for executing the firm’s strategy. HR success drivers are the core people related competencies and capabilities or assets such as employee productivity or employee satisfaction which are considered to be so important and unique to a particular firm for the attainment of its objectives. The study examines how these HR performance drivers serve as a catalyst for achieving organizational objectives .Through interviews and the review of empirical data, the study found that human resource managers tend to focus on HR performance drivers such as employee satisfaction, employee turnover, absenteeism in attempting to demonstrate their strategic influence as well as the difficulty in measuring HR’s actual contribution to overall mission and strategy. It recommends the need for holistic business performance measurement indicators that promote value addition and places premium on HR as a function within the organization.
An Evaluation of Confirmatory Factor Analysis of Ryff’s Psychological Well-Being Scale in a Persian Sample (Published)
This paper examines the construct validity and reliability of the Psychological Well-Being Scale (PWBS) according to the Persian culture and language. Participants (N=577) from a population study of university students were chosen. Confirmatory factor analysis using AMOS software was performed in two steps. In step one, 18 models derived from 3-, 9-, and 14-item forms that emphasized gender differences in addition to first and second order constructs were compared. In step two, the 9-and 14-item forms were compared aiming modification. In step one only the 3-item form achieved reasonable indices. Allowing for gender differences did not result in a model fit in the 9-and 14-item forms. To achieve a model fit with additional items, in step two, models that used the 9- and 14-item forms with a second order factor structure regardless of gender differences was performed for modification. This modification allowed for greater potential for comparison with other models in order to achieve good indices. The results in step two indicated that after deleting of some items from the two models, the 14-item model showed better construct validity and reliability compared to the model based on the 9-item form in the Persian culture.
Global Solar Radiation Measurement in Abakaliki Ebonyi State Nigeria Using Locally Made Pyranometer (Published)
This research work focused on the variability of global solar radiation over the area of Abakaliki, Ebonyi State (6o20’N, 8o06’E) located in South Eastern part of Nigeria for the rainy and dry seasons. The Pyranometer used for this measurement was locally developed and calibrated against a standard pyranometer, it competed favorably with the standard Einstrain Lungs Sensor. The global solar radiation was measured every five minutes from 08:00hours to 18:00hours during the dry season 2011 and rainy season in 2012. The measurements were carried out near the New Physics Laboratory Complex Ebonyi State University Abakaliki, Nigeria. Maximum Irradiances of 1095.10Wm-2 and 689.48Wm-2 recorded in Abakaliki during dry and rainy seasons respectively occurred between 12:00 – 14:00hours local time, whereas the minimum values of 9.20Wm-2 and 9.86Wm-2 respectively are recorded during the sunrise and sunset. Partly cloudy conditions in Abakaliki cause conspicuous oscillations in global solar radiation. This can be attributed to multiple reflections by nearby cloudy layers. The seasonal difference in the observed global solar radiation was 405.62Wm-2. Therefore solar energy devices can operate continuously in Abakaliki for up to 10 hours in a solar day from 8:00hours to 18:00hours which was the period covered during this investigation.
Develop a model for measuring customer satisfaction in chain stores”” Case study: Yas Store (Review Completed - Accepted)
Discovering customer requirements and needs then fulfilling them better and more efficiently than competitors cause customer satisfaction; therefore, it can be one of the requirements of the company’s success recently. The purpose of this paper is to propose and evaluate a model for measuring customer satisfaction in Yas store. This study is a descriptive survey that Yas store’s customers form the sample; 384 customers are selected by using non-random sampling of the kind of judgment method. Questionnaire is the main tool of this research for data collection. The research model was tested using path analysis that results indicate a significant relationship among customer expectations, employees’ behaviors and store indexes with customer satisfaction in Yas shop.
