Fulltext How do locus of control influence business and personal success? The mediating effects of entrepreneurial competency

Hamzah MI, Othman AK

Front Psychol, 2022;13:958911.
PMID: 36687850 DOI: 10.3389/fpsyg.2022.958911

This research aims to assess the influence of locus of control on the expression of entrepreneurial competency in a small business setting. Specifically, it predicts how this can generate positive outcomes in terms of business growth, quality of life, and sustainable entrepreneurial intention. Survey responses were collected from 102 small-sized firms in Malaysia. Structural equation modeling was performed to validate a mediation model and test nine research hypotheses. The results suggested that internal locus of control indirectly affects the venturing outcomes via entrepreneurial competency, whereas external locus of control has no such consequences. Thus, it can be deduced that beliefs based on internal attributions-rather than external forces, define entrepreneurs' destiny, and their competencies serve a perpetual role in linking these beliefs to positive business performance, life satisfaction, and sustainable entrepreneurial behavior. In practical terms, policymakers may gradually shift their focus from supplying direct financial relief assistance to the owner-managers to empowering them with core competencies building programs, especially during disasters and recessions. This study unravels the complexities of the entrepreneurial psychology-competency interface and fills a gap in the literature by providing compelling evidence of the adverse consequences of relying too heavily on fate or external assistance.
The mediating role of work-related musculoskeletal disorders on the link between psychosocial factors and absenteeism among administrative workers

Abdullah MZ, Othman AK, Ahmad MF, Justine M

Soc Work Public Health, 2015;30(1):64-74.
PMID: 25375935 DOI: 10.1080/19371918.2014.938393

This study aimed to investigate the association between psychosocial factors (i.e., job demand, decision latitude, social support, physical environment, and personal risk factors), work-related musculoskeletal disorders (WRMDs), and productivity as measured by workers' perceived absenteeism. Data were collected from the selected administrative workers (administrative assistant) and analyzed using cross tabulation. The results indicate that all psychological factors are not significantly associated with WRMDs, except for the association between personal risk factors and hip/thigh disorders. Subsequently, WRMDs do not significantly contribute to explaining absenteeism. The managerial and research implications of this study are deliberately discussed.

INTRODUCTION: Brain tumour (BT) is a tremendous burden on patients, families as well as the surrounding communities, especially the healthcare services. It can be classified into either a benign slow growing tumour (non-cancerous) and malignant tumour (cancerous). The purpose of this study was to determine the incidence and pattern of brain tumour admitted to the Neurosurgery Department in Hospital Sultanah Nurzahirah (HSNZ), Terengganu, Malaysia.
METHODS: This is a retrospective study of incidence and pattern of BT admitted to the Neurosurgery Department in HSNZ. Data was collected from the yearly census of BT registered from 2013 to 2018.
RESULTS: A total number of 386 new cases of primary BT were registered. The number of cases of BT was found to be lowest among children (0 to 10 years old) with only 4.4% but at peak among elderly aged between 51 to 60 years old (26.2%). As for gender, males constituted about 44.5% (n=172) whereas females accounted for 55.5% (n= 214) of the cases. In total, meningioma was found to have the highest incidence (27.2%) followed by metastases brain tumour (18.1%) and glioma (17.4%).
CONCLUSIONS: This study has shown that the incidence of BT was led by meningioma which had a high prevalence among the elderly population, followed by metastasis BT and gliomas.
Comparison of Combination Between Ketamine and Parecoxib as Multimodal Preemptive Analgesia With Ketamine Alone for Elective Laparotomy

Asian J Anesthesiol, 2021 Dec 01;59(4):161-168.

BACKGROUND: Preemptive analgesia is important for reducing postoperative analgesia requirement. Therefore, this study compared the efficacy of intravenous (IV) ketamine alone with the efficacy of a combination of low-dose IV ketamine and IV parecoxib as part of a multimodal preemptive analgesia regimen in patients undergoing elective laparotomy.
METHODS: In this prospective study, 48 patients scheduled for elective laparotomy were randomized to two groups of preemptive analgesia, namely, group K-P, in which anestheologists administered a combination of 0.3 mg/kg IV ketamine and 40.0 mg IV parecoxib, or group K, in which ones gave 0.3 mg/kg IV ketamine alone. Patients from both groups underwent surgery under general anesthesia, and total intraoperative opioid requirement was recorded. After surgery, morphine administered by automated patient-controlled analgesia (PCA) infusion device was initiated in all patients. Pain score was assessed using the visual analogue scale (VAS), and postoperative opioid requirement was recorded at 1 and 4 hours, and subsequently from 4-hour intervals up to 24 hours after surgery.
RESULTS: Compared to group K, group K-P required significantly lower rescue IV fentanyl in the recovery bay (0.10 ± 0.28 vs. 0.35 ± 0.46 μg/kg; P = 0.031), showing prolonged time-to-first analgesic request recorded by PCA device (70.8 ± 40.0 vs. 22.2 ± 15.8 mins; P ＜ 0.001), lower total morphine requirement delivered by PCA device (8.0 ± 4.6 vs. 16.8 ± 6.5 mg; P ＜ 0.001), and lower VAS values measured at all time points. There was no significant difference in intraoperative total opioid requirement between the groups.
CONCLUSIONS: Among laparotomy patients, multimodal preemptive analgesia by the use of a combination of low-dose IV ketamine and IV parecoxib was more effective than IV ketamine alone in reducing pain scores and postoperative analgesia requirement (e.g., PCA-administered morphine).
