Pathogens Assessment in Reclaimed Effluent Used for Industrial Crops Irrigation
R. Al-Sa`ed
International Journal of Environmental Research and Public Health , 2007, DOI: 10.3390/ijerph2007010011
Abstract: Reuse of treated effluent is a highly valued water source in Palestine, however with limited success due to public health concerns. This paper assesses the potential pathogens in raw, treated and reclaimed wastewater at Albireh urban wastewater treatment facility, and provides scientific knowledge to update the Palestinian reuse guidelines. Laboratory analyses of collected samples over a period of 4 months have indicated that the raw wastewater from Albireh city contained high numbers of fecal coliforms and worm eggs while 31% of the samples were Salmonella positive. Treated effluent suitable for restricted irrigation demonstrated that the plant was efficient in removing indicator bacteria, where fecal coliforms and fecal streptococci removal averaged 99.64% and 93.44%, respectively. Although not disinfected, treated effluent was free of Salmonella and parasites, hence safe for restricted agricultural purposes. All samples of the reclaimed effluent and three samples of irrigated grass were devoid of microbial pathogens indicating a safe use in unrestricted agricultural utilization. Adequate operation of wastewater treatment facilities, scientific updating of reuse guidelines and launching public awareness campaigns are core factors for successful and sustainable large-scale wastewater reuse schemes in Palestine.

Mahfuz Judeh
International Business Research , 2011, DOI: 10.5539/ibr.v4n3p171
Abstract: The aim of this study was to examine the relationship between employee socialization and organization commitment. The study also aimed at assessing the mediating effect of role ambiguity and role conflict on the relationship between employee socialization and organization commitment in a large telecommunication organization located in Jordan. A survey was administered to 300 employees, and 256 questionnaires were returned and usable for statistical analysis. Descriptive statistics, correlations and regression analyses were used to test the hypotheses. Findings reported that both proposed mediators, role ambiguity and role conflict, emerged as significant mediators of the relationship between employee socialization and organization commitment. Based on the findings and limitations of the study, further research was needed to examine the correlation of socialization, job stressors, and organizational commitment on other work environments.

Mahfuz Judeh
International Business Research , 2012, DOI: 10.5539/ibr.v5n5p88
Abstract: This study attempted to examine the effect of two selected personality traits on intent to leave. A theoretical framework was proposed to suggest link among the two variables and a questionnaire was distributed to collect data from employees in insurance corporations in Jordan. Of the 500 questionnaires distributed, 331 valid responses were received, resulting in a 66.2% response rate. The results revealed that both conscientiousness and extraversion were negatively related to intent to leave. As for the results of the demographic factors, the study showed that there were significant differences in intent to leave based on gender and age, while there were no significant differences due to marital status. Finally, this study suggested that management should adopt appropriate strategies and enhance human resource practices that lead to positive personality traits which lead to increased retention of employees.

Mahfuz Judeh
International Journal of Business and Management , 2011, DOI: 10.5539/ijbm.v6n9p202
Abstract: The aim of this study was to determine the level of employee involvement and extent of teamwork effectiveness among employees working in the Jordanian glass and ceramic industries listed in Amman Stock Exchange in Jordan. The study aimed also at examining the significant effect of employee empowerment on teamwork effectiveness. Furthermore, the study investigated the significant differences that may exist in employee involvement due to differences in age, marital status, and educational level. Data were collected from 176 participants and then analyzed using descriptive statistics, one sample t-test and independent sample t-test, linear regression, and ANOVA. Findings indicated that both employee involvement and teamwork effectiveness were at a high to moderately high level score. Furthermore, the findings of the study revealed a significant effect of employee involvement on teamwork effectiveness. At the same time results indicated that there were no significant differences towards employee involvement due to gender or marital status, while participants significantly differed in terms of educational level. The results of this study had many implications for human resources and other practitioners and managers who must enhance the teamwork atmosphere in their organizations. As for the originality/value, employee involvement and teamwork effectiveness had previously lacked attention, especially in the Middle East countries, and this paper contributed to the body of knowledge by empirically studying the correlation between employee involvement and teamwork effectiveness.
Sustainability of Ancient Water Supply Facilities in Jerusalem

Sustainability , 2009, DOI: 10.3390/su1041106
Abstract: This paper presents an overview on the sustainability of ancient water supply systems in Jerusalem from the Chalcolithic period (4500–3200 B.C.) until the present time. Archaeological evidences and landscape settings were applied utilizing all available and accessible literature relevant to ancient water resources management in Jerusalem. Irrigated agriculture was practiced for many centuries in this region, hence sustainable water supply facilities were erected, including well developed aqueducts, water harvesting pools and irrigation channels for water storage and landscaping purposes. To cope with seismic events, soil subsidence and water leakage, ancient water engineers and architects applied innovative construction methods for the erection of water pools, channels and aqueduct systems. Ancient water supply systems in Jerusalem are valuable treasures of past civilizations and crucial urban environmental facilities and their protection is consistent with sustainable development principles. Effective environmental assessment as a decision-making process for sustainable development can be applied to preserve threatened ancient water facilities from major development proposals and urban infrastructure projects in Jerusalem.

Abstract: Background: Mother to child transmission of HIV infection (vertical transmission) is of major concern, because of the attendant consequences of morbidity and mortality on the child. The success of a prevention of mother to child transmission (PMTCT) programme in reducing sero-conversion among exposed newborn infants is determined by many factors, including the administration of Anti Retroviral drugs to both HIVpositive mothers and their newborns; infant feeding practices; access to and use of well-baby care; and the health system's ability to provide care, including counseling and support to both the HIV-positive mother and her exposed newborn. Aim: This study is aimed at examining the various infant feeding choices and practices as risk factors of mother to child transmission of HIV among exposed infants in Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Anambra State, Nigeria. Method: The study design is descriptive cross-sectional. A total of 288 consenting HIV positive mothers of recruited children were selected using the systematic sampling technique. Data were collected using a pre-tested structured interviewer-administered questionnaire, and analyzed by means of the Statistical Package of Social Sciences (SPSS) software. Result: The mean age of the respondents was 30.46+4.86 years. Majority of the patients were married, and most of them were traders. Inadequate receipt of replacement feed, breastfeeding of an HIV exposed infant, duration of breast feeding among others constitute significant determinants of current health status of baby (p<0.05, p<0.01 and p<0.006 respectively. Conclusion: Infant feeding counseling should be reinforced and the practices strengthened and monitored closely in the PMTCT program so as to significantly reduce child/infant morbidity and mortality on one hand, and transmission of HIV infection from the mothers to their children, on the other.

Abstract: Background and Objective: Because high-dose angiotensin-converting enzyme (ACE) inhibitor therapy is desirable in patients with chronic heart failure (CHF), we sought to determine the usage and dosing patterns of ACE inhibitors in CHF patients at a governmental hospital in Palestine. Methods: This cross-sectional study was conducted between September 2006 and August 2007. All patients admitted with a confirmed diagnosis of CHF and an ejection fraction < 40% were evaluated. After excluding patients with a caution/contraindication to ACE inhibitor use or not taking an ACE inhibitor, we determined the number of patients receiving optimal (captopril 150-300 mg/day, enalapril 20-40 mg/day, ramipril 5-10 mg/day) and suboptimal doses. We then conducted statistical analyses to evaluate associations between ACE inhibitor use and dosing and various demographic and clinical factors. Results: Of the 165 patients initially evaluated, 69 (41.8%) had a caution/contraindication (n=28, 40.6%) or were not using an ACE inhibitor (n=41, 59.4%). Of the remaining 96 patients (70.1%), 49/96 (51%) were given an optimal dose while 47/96 (49%) were given a suboptimal dose. Of all patients with CHF and no contraindi--cation (n=137), 88 (64.2%) were either receiving no ACE inhibitor or a suboptimal dose. Only the presence of hypertension was significantly associated with the use of an ACE inhibitor (P=.009, odds ratio=2.7). The use of an optimal dose was not significantly associated with any of the tested factors (age, gender, presence of hyper--tension, diabetes mellitus, renal dysfunction, ischemic heart disease or number of diagnosis) . Conclusion: Underutilization and suboptimal dosing of ACE inhibitors was common. Since there is an abun--dance of evidence in favor of using high-dose ACE inhibitor therapy in patients with CHF, physicians need to be educated about proper dosing of these agents.

International Business Management , 2012, DOI: 10.3923/ibm.2012.264.269
Abstract: Trust within organization plays an important role in enhancing the interaction among superiors and subordinates which are reflected on the way effective organizational goals are achieved. One of the core functions of effective manager is to enhance confidence climate with his/her relations with peers and subordinates. Furthermore, employee empowerment has become an important management approach to motivate subordinates and lead them in an efficient manner. Employee empowerment involves delegation of authority through which lower level management can make autonomous decisions without referring to their superiors. Data were collected from a sample of 206 participants whose responses were usable for statistical analysis. Descriptive analysis, one sample t-test and linear regression are performed to reach the final results. Results of the study indicate that trust is at a medium degree while employee empowerment is at a high level. At the same time, results show that there is a significant correlation between within organization trust and employee empowerment. It is hoped that this study will offer some insight for the importance of within organization trust to all management approaches and techniques, especially in effective employee empowerment. The study proposes several directions for further research such as conducting more empirical studies on the antecedents and outcomes of both within organization trust and employee empowerment.
