The effect of piety on organizational citizenship behavior (OCB) from Islamic perspective: a study of professionals in Southeast Asia

Although Organizational Citizenship Behavior (OCB) has received much attention from contemporary researchers, very little research has been done from religious perspectives. This research attempts to enrich the understanding of OCB from Islamic Management perspective, particularly the application of Piety (Taqwa). The exploratory study consists of six intensive interviews, three academics and three practitioners, who were selected from two South-East Asian countries; Malaysia and Indonesia. The respondents represent prestigious academic institutions and top private organizations. The findings from the interviews led to the following propositions that; (1) there is a nexus between OCB and Taqwa; (2) Taqwa and other Islamic principles may serve as antecedents or enabling factors to OCB; and (3) Taqwa should be operationalized for contemporary business research

Thermal-Hydraulic performance in a microchannel heat sink equipped with longitudinal vortex generators (LVGs) and nanofluid

In this study, the numerical conjugate heat transfer and hydraulic performance of nanofluids flow in a rectangular microchannel heat sink (RMCHS) with longitudinal vortex generators (LVGs) was investigated at different Reynolds numbers (200-1200). Three-dimensional simulations are performed on a microchannel heated by a constant temperature with five different configurations with different angles of attack for the LVGs under laminar flow conditions. The study uses five different nanofluid combinations of Al2O3 or CuO, containing low volume fractions in the range of 0.5% to 3.0% with various nanoparticle sizes that are dispersed in pure water, PAO (Polyalphaolefin) or ethylene glycol. The results show that for Reynolds number ranging from 100 to 1100, Al2O3-water has the best performance compared with CuO nanofluid with Nusselt number values between 7.67 and 14.7, with an associated increase in Fanning friction factor by values of 0.0219-0.095. For the case of different base fluids, the results show that CuO-PAO has the best performance with Nusselt number values between 9.57 and 15.88, with an associated increase in Fanning friction factor by 0.022-0.096. The overall performance of all configurations of microchannels equipped with LVGs and nanofluid showed higher values than the ones without LVG and water as a working fluid

Investigating the dimensionality of organisational citizenship behaviour from islamic perspective (ocbip): empirical analysis of business organisations in southeast Asia

Although Organisational Citizenship Behaviour (OCB) emanating from the Western value system has received enormous attention by researchers, OCB from the Islamic perspective (OCBIP) has not been much explored. This empirical study attempts to enrich the understanding of the OCB phenomenon from Islamic management perspective. A survey of 405 Muslim employees in business organisations in Malaysia was drawn for the study. The construct validity of OCBIP via Chartered Financial Analyst (CFA) led to the major finding; the OCBIP measurement model in the business organisational context is explained by four components; Altruism, Civic virtue, Advocating high moral standards and Removal of harm

Immunogenicity of the biosimilar CT-P13 infliximab or the original infliximab in Iraqi patients with Ankylosing spondylitis does not correlate with their demographic characteristics

Background: Ankylosing spondylitis is a rare disease affecting people with hereditary factors. Its treatment includes life style modification and use of drugs such as the biologic agent infliximab or its biosimilar, CT-P13 infliximab. Despite their therapeutic usefulness, these agents are associated with a number of serious adverse effects such as immunogenicity. Objectives: The aim of current study was to investigate if immunogenicity of the biosimilar CT-P13 infliximab or the original infliximab, in Iraqi patients with Ankylosing spondylitis, is affected by any of the patients’ demographic characteristics. Methods: A retrospective open-label study was conducted from December 2021 to March 2022 at the Rheumatology Unit, Baghdad Teaching Hospital/Medical City, Baghdad. Forty-four patients were taking Infliximab, and another 50 patients were taking CT-P13, both at a dose of 5mg/kg for 3 months prior to recruitment in current study. Disease activity was assessed by ASDAS-CRP score while antibodies and C-reactive protein were tested by Enzyme-Linked Immunosorbent Assay technique. Statistical analyses were performed using SPSS statistical package for Social Sciences version 20.0. The level of significance was considered at P<0.05. Results: There was non-significant correlation between anti-infliximab antibodies and demographic data of patients (P>0.05). Similar data were reported regarding the biosimilar CT-P13 infliximab except for smoking and disease activity which exhibited significant correlation with development of anti-CT-P13 antibodies (P<0.05). Conclusion: Immunogenicity of the biosimilar CT-P13 infliximab, but not that of the original Infliximab, may be influenced by demographic characteristics or disease activity in patients with ankylosing spondylitis

The measurement model of social responsibility construct from an Islamic perspective: empirical analysis of Malaysian business organizations

The present study investigates the measurement model of the Islamic social responsibility (ISR) construct in business organizations in the Malaysian context. The study aims to contribute new knowledge to the existing literature of Social responsibility (SR) in general, and ISR in particular. Using disproportionate stratified random sampling, the survey data used for this empirical research was drawn from 405 Muslim employees in business organizations in Malaysia. After yielding an instrument to measure ISR, Principal Component Analysis (PCA) using SPSS version 18.0, and Confirmatory Factor Analysis (CFA) using AMOS version 18.0 were conducted. Good fit indices from CFA revealed that, the ISR measurement model in the Malaysian business organizational context is explained by five components; Integrity, Emotional Control, Fulfillment of Covenant, Justice and Truthfulness. Theoretical and practical implications from the study were further discussed. Human Resource Development professionals, organizational managers and government authorities may use the findings of this study to justify their efforts in designing appropriate learning and performance improvement interventions so that ISR of employees can be monitored and further enhanced

The Frequency of Hypothyroidism in Middle Aged Women Suffering From Headache in Diyala Governorate

Background:The previous researches show that the hypothyroidism occurs in approximately 1–2% of women and 0.1% of men and is characterized by a TSH level above the normal reference range and a T4 level below the reference range. This percentage indicate that: women have ten times the risk of hypothyroidism as men, with the difference became significant above the age of 34 years. Hypothyroidism may very easily be missed due to the similarity between the symptoms of hypothyroidism and that of menopause.Many middle-age women complained from headache whether it is tension headache or migraine and since headache is one of the symptoms of hypothyroidism, so there will be many cases of misdiagnosed hypothyroidism. This study estimates thyroid function test for those women to shed a light for the frequency of hypothyroid women. Objective: To current study screening middle- aged women suffering from headache by thyroid function test to treat these women properly and not only treat the headache as a separate complain Patients and Methods: Three hundred (300) women aged between 35 -55 years with headache included in this study, their chief complain is only headache, they have no other medical conditions or chronic diseases. They were divided in to two groups; the first group aged from (35- 45 years), while the second one aged from (46-55 years). Three hundred (300) healthy women aged between (35-55 years) are screened for TFT (thyroid function test) as a control group were divided in to two groups; the first group aged from (35-45 years) while the second group aged between (46-55 years). Thyroid function test (TSH, T3, and T4) were done for all groups. Results: There are 53(17.6%) women in patients group have high TSH with low T3 and T4 which means that they have overt hypothyroidism and 17(5.7%) women in the same group have only high TSH which means that they have (subclinical) hypothyroidism, while 230 (76.7%) women have normal thyroid function test. This means that: the total number of hypothyroid women is 70 (23.3%) which is regarded as high percentage. Conclusion:There is a high percentage of women suffering from headache having hypothyroidism so thyroid function test should be done for all middle-aged women with from headache

A Systematic Review on Cardiovascular Stent and Stenting Failure: Coherent Taxonomy, Performance Measures, Motivations, Open Challenges and Recommendations

Cardiovascular stenting is a mature topic but it is still being developed in the research community because of its importance. To provide worthy information about cardiovascular stenting environments and to give support to the researchers, attention must be given to understand the obtainable choices and gaps in this research field. This work aims to examine and examine the literature of each work related to the placement of cardiovascular stents, the failure of the stents and the models of stent designs to provide a good understanding through the investigation of articles published in various contextual aspects, such as motivations, open-challenges and recommendations to improve the field of stent placement. A systematic review is carried-out to map and examine the articles related to cardiovascular stents, the failure of the stents and the models of stent designs through a coherent-taxonomy used in three well-known scientific databases: ScienceDirect, IEEE Explore, and Web of Science. These databases involve literature that highlight arterial stenting. Based-on our inclusion and exception, a total of 90 articles composed the final set that offer various classes and sub-classes. The first class includes the development studies with (42/90) of experimental, computational and combined experimental and computational studies related to stent models performance and stent failure, the second class discussed studies that have been performed on stent design with (32/90), the third class is focused on the framework studies with (10/90), and the fourth class includes problems of stenting long-term with (6/90). The performance of stent designs, which is a research area that requires periodic controls, tools and procedures that could provide a stent design with good mechanical performance, reduce restenosis in the stent and increase fatigue resistance and durability. There have been numerous studies on stent performance that could promise good results in this field. The fields of research in stent designs vary, but all fields are fundamental equally. The expectation of this work could help to emphasize present research chances and, therefore, expand and make further research fields

Degradation of Indigo Dye Using Quantum Mechanical Calculations

The semiempirical (PM3) and DFT quantum mechanical methods were used to investigate the theoretical degradation of Indigo dye. The chemical reactivity of the Indigo dye was evaluated by comparing the potential energy stability of the mean bonds. Seven transition states were suggested and studied to estimate the actually starting step of the degradation reaction. The bond length and bond angle calculations indicate that the best active site in the Indigo dye molecule is at C10=C11.  The most possible transition states are examined for all suggested paths of Indigo dye degradation predicated on zero-point energy and imaginary frequency. The first starting step of the reaction mechanism is proposed. The change in enthalpy, Gibbs free energy and change in entropy of the overall reaction are equal to -548268.223 kcal/mol, 30831.951 kcal/mol and 48.552 cal/mol.deg, respectively. The activation energy is 46176.405 kcal/mol. The reaction rate is equal to

PREDICTING OF STEAM CONDENSATION HEAT TRANSFER COEFFICIENT IN HORIZONTAL FLATTENED TUBE

The heat transfer coefficient of steam condensation has a significant role in the performance of air-cooled heat exchangers. The purpose of this work is to predict the local/average local steam condensation heat transfer coefficient inside the horizontal flattened tube under vacuum conditions using numerous correlations that were developed by some researches which have been conducted under specified conditions. The results from these correlations have been compared with experimental data of Davies, therefore more investigate for the values are necessary to improve or/and validate the existing correlations. The effect of such parameters like the uniform heat flux and saturation temperature also have been studied on the local steam condensation heat transfer coefficient as the results show that the heat transfer coefficient decrease as the heat flux increase, while it increases as the steam saturated temperature increase
