The role of environment on women's perception about their STEM studies: observations from a Global South country.

The growing global demand for STEM professionals is not being met by the supply of new graduates, a supply that is characterised by a significant lag in the percentage of women pursuing STEM studies. Interestingly enough, the percentage of female applicants entering STEM majors has been increasing yet only a minority of them pursue, or complete, engineering programs. Several studies for the developed world have identified several environmental factors responsible for this phenomenon. The scarcity of engineering professionals is a handicapping factor for development, even for the most advanced countries of the Global South. The objective of this exploratory study is to examine whether the environmental factors identified in the international literature are sufficient to explain the asymmetry in selecting an engineering or a natural sciences career among female undergraduates in an exemplary Global South country, Kazakhstan. To this purpose, a multifaceted survey was conducted among the female students pursuing STEM majors in the premier Kazakhstani university in the academic year 2021-2022. This study utilized a Likert Scale questionnaire, ordinal logistic regression, and factor analysis to explore factors affecting female students. Data reliability was confirmed through Confirmatory Factor Analysis (CFA). The factor and regression analysis of the results obtained demonstrates that there is no discernible difference between the observations in the literature and the situation in Kazakhstan.

Near-infrared spectroscopy for intracranial hemorrhage detection in traumatic brain injury patients: A systematic review.

PURPOSE: To synthesize evidence of the use of near-infrared spectroscopy (NIRS) to detect intracranial hemorrhage in traumatic brain injury (TBI) patients. METHODS: The literature search was conducted in PubMed and Google Scholar (from inception to July 2021). RESULTS: 216 original articles were found, 197 of which were omitted, and the final review contained 19 original articles covering 2291 patients. CONCLUSION: For patients with TBI, a NIRS test may be useful as a screening tool for intracranial hemorrhage, especially at the prehospital level. Negative results may help rule out intracranial hemorrhage and may remove the need for more head computed tomography (CT) scanning. Prehospital testing may guide the decision of whether the patient should be transferred to a craniotomy-equipped specialized hospital. NIRS can also be useful in situations when CT is not available. For future research, a significant objective is to show whether the effects of NIRS can improve outcomes and lead to meaningful improvements in clinical practice and decision making.
