Gender Stereotypes and Teachers Perceptions (The Case of Pakistan)

The purpose of this study is to investigate the attitude and perception of university teachers towards students’ gender role. A self-administrated questionnaire was used to engender the responses from 155 university teachers of private  and public sector  universities in Pakistan and responses were analyzed according to gender and education in order to find out that why they show biasness towards male and female students and how gender-stereotype is played out by teachers in the classroom. In this paper we will also analyze that how these demographic independent variables effects the belief and perception of teachers regarding students’ gender role. Results indicate that teachers have different behavior towards male and female students and it is due to teacher’s perceptions and attitude toward their students’ gender role. Result shows that discrimination by teachers towards the students’ gender role in public and private sector universities as well as age, qualification, designation, language, marital status and ownership have significant relationship with students’ gender biasness. This relationship has not been investigated in Pakistan before so our study is with the purpose to empirically get an insight to Pakistan. As teacher gender role stereotyping is the most considerable factor in educational differences of gender but there are few studies focusing on it. It is agreed that teachers have the greatest influence on educational stereotypes so; our study is part of the minority effort to deal with this problem.

Effect of lipid-based nutrient supplement-Medium quantity on reduction of stunting in children 6-23 months of age in Sindh, Pakistan: A cluster randomized controlled trial

Background: Chronic childhood malnutrition, or stunting, remains a persistent barrier to achieve optimal cognitive development, child growth and ability to reach full potential. Almost half of children under-five years of age are stunted in the province of Sindh, Pakistan.Objective: The primary objective of this study was to test the hypothesis that the provision of lipid-based nutrient supplement-medium-quantity (LNS-MQ) known as Wawamum will result in a 10% reduction in risk of being stunted at the age of 24 months in the intervention group compared with the control group.Design: A cluster randomized controlled trial was conducted in Thatta and Sujawal districts of Sindh province, Pakistan. A total of 870 (419 in intervention; 451 in control) children between 6-18 months old were enrolled in the study. The unit of randomization was union council and considered as a cluster. A total of 12 clusters, 6 in each study group were randomly assigned to intervention and control group. All children received standard government health services, while children in the intervention group also received 50 grams/day of Wawamum.Results: Children who received Wawamum were found to have a significantly reduced risk of stunting (RR = 0.91, 95% CI; 0.88-0.94, p\u3c0.001) and wasting (RR = 0.78, 95% CI; 0.67-0.92, p = 0.004) as compared to children who received the standard government health services. There was no evidence of a reduction in the risk of underweight (RR = 0.94, 95% CI; 0.85-1.04, p = 0.235) in the intervention group compared to the control group. Statistically significant reduction in anaemia in the intervention group was also found as compared to the control group (RR = 0.97, 95% CI; 0.94-0.99, p = 0.042). The subgroup analysis by age, showed intervention effect is significant in reduction of risk of stunting in younger children of aged 6-12 month (RR = 0.83, 95% CI; 0.81-0.86, p = \u3c0.001) and their older peers aged 13-18 month- (RR = 0.90, 95% CI; 0.83-0.97, p = 0.008). The mean compliance of Wawamum was 60% among children.Conclusions: The study confirmed that the provision of Wawamum to children 6-23 months of age is effective in reducing the risk of stunting, wasting and anaemia. This approach should be scaled up among the most food insecure areas/households with a high prevalence of stunting to achieve positive outcomes for nutrition and health. This study was registered at clinicaltrials.gov as NCT02422953. Clinical Trial Registration Number: NCT02422953

Prevalence and possible factors associated with anaemia, and vitamin B \u3csub\u3e\u3csub\u3e12\u3c/sub\u3e\u3c/sub\u3e and folate deficiencies in women of reproductive age in Pakistan: Analysis of national-level secondary survey data

Objective: To determine the prevalence and possible factors associated with anaemia, and vitamin B12 and folate deficiencies in women of reproductive age (WRA) in Pakistan.Methods: A secondary analysis was conducted on data collected through the large-scale National Nutrition Survey in Pakistan in 2011. Anaemia was defined as haemoglobin levels \u3c12 g/dL, vitamin B12 deficiency as serum vitamin B12 levels of \u3c203 pg/mL (150 pmol/L) and folate deficiency as serum folate levels \u3c4 ng/mL (10 nmol/L).Results: A total of 11751 blood samples were collected and analysed. The prevalence of anaemia, vitamin B12 deficiency and folate deficiency was 50.4%, 52.4% and 50.8%, respectively. After adjustment, the following factors were positively associated with anaemia: living in Sindh province (RR 1.07; 95%CI 1.04 to 1.09)P\u3c0.00, food insecure with moderate hunger (RR 1.03; 95%CI 1.00 to 1.06)P=0.02, four or more pregnancies (RR 1.03; 95%CI 1.01 to 1.05)P\u3c0.00, being underweight (RR 1.03; 95%CI 1.00 to 1.05)P=0.02, being overweight or obese (RR 0.95; 95%CI 0.93 to 0.97)P\u3c0.00 and weekly intake of leafy green vegetables (RR 0.98; 95%CI 0.95 to 1.00)P=0.04. For vitamin B12 deficiency, a positive association was observed with rural population (RR 0.81; 95%CI 0.66 to 1.00)P=0.04, living in Khyber Pakhtunkhwa province (RR 1.25; 95%CI 1.11 to 1.43)P\u3c0.00 and living in Azad Jammu and Kashmir (RR 1.50; 95%CI 1.08 to 2.08)P=0.01. Folate deficiency was negatively associated with daily and weekly intake of eggs (RR 0.89; 95%CI 0.81 to 0.98)P=0.02 and (RR 0.88; 95%CI 0.78 to 0.99)P=0.03.Conclusions: In Pakistan, anaemia, and vitamin B12 and folate deficiencies are a severe public health concern among WRA. Our findings suggest that further research is needed on culturally appropriate short-term and long-term interventions within communities and health facilities to decrease anaemia, and vitamin B12 and folate deficiencies among Pakistani women

Investigating Novice Developers’ Code Commenting Trends Using Machine Learning Techniques

Code comments are considered an efficient way to document the functionality of a particular block of code. Code commenting is a common practice among developers to explain the purpose of the code in order to improve code comprehension and readability. Researchers investigated the effect of code comments on software development tasks and demonstrated the use of comments in several ways, including maintenance, reusability, bug detection, etc. Given the importance of code comments, it becomes vital for novice developers to brush up on their code commenting skills. In this study, we initially investigated what types of comments novice students document in their source code and further categorized those comments using a machine learning approach. The work involves the initial manual classification of code comments and then building a machine learning model to classify student code comments automatically. The findings of our study revealed that novice developers/students’ comments are mainly related to Literal (26.66%) and Insufficient (26.66%). Further, we proposed and extended the taxonomy of such source code comments by adding a few more categories, i.e., License (5.18%), Profile (4.80%), Irrelevant (4.80%), Commented Code (4.44%), Autogenerated (1.48%), and Improper (1.10%). Moreover, we assessed our approach with three different machine-learning classifiers. Our implementation of machine learning models found that Decision Tree resulted in the overall highest accuracy, i.e., 85%. This study helps in predicting the type of code comments for a novice developer using a machine learning approach that can be implemented to generate automated feedback for students, thus saving teachers time for manual one-on-one feedback, which is a time-consuming activity

After adjustment, the following factors were positively associated with anaemia: living in Sindh province (RR 1.07; 95% CI 1.04 to 1.09) PConclusions: In Pakistan, anaemia, and vitamin B12 and folate deficiencies are a severe public health concern among WRA. Our findings suggest that further research is needed on culturally appropriate short-term and long-term interventions within communities and health facilities to decrease anaemia, and vitamin B12 and folate deficiencies among Pakistani women

Mechanistic evaluation of a novel cyclohexenone derivative?s functionality against nociception and inflammation: An in-vitro, in-vivo and in-silico approach

The synthesis of a novel cyclohexanone derivative (CHD; Ethyl 6-(4-metohxyphenyl)-2-oxo-4-phenylcyclohexe-3-enecarboxylate) was described and the subsequent aim was to perform an in vitro, in vivo and in silico pharmacological evaluation as a putative anti-nociceptive and anti-inflammatory agent in mice. Initial in vitro studies revealed that CHD inhibited both cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) enzymes and it also reduced mRNA expression of COX-2 and the pro-inflammatory cytokines TNF-α and IL-1β. It was then shown that CHD dose dependently inhibited chemically induced tonic nociception in the abdominal constriction assay and also phasic thermal nociception (i.e. anti-nociception) in the hot plate and tail immersion tests in comparison with aspirin and tramadol respectively. The thermal test outcomes indicated a possible moderate centrally mediated anti-nociception which, in the case of the hot plate test, was pentylenetetrazole (PTZ) and naloxone reversible, implicating GABAergic and opioidergic mechanisms. CHD was also effective against both the neurogenic and inflammatory mediator phases induced in the formalin test and it also disclosed anti-inflammatory activity against the phlogistic agents, carrageenan, serotonin, histamine and xylene compared with standard drugs in edema volume tests. In silico studies indicated that CHD possessed preferential affinity for GABAA, opioid and COX-2 target sites and this was supported by molecular dynamic simulations where computation of free energy of binding also favored the formation of stable complexes with these sites. These findings suggest that CHD has prospective anti-nociceptive and anti-inflammatory properties, probably mediated through GABAergic and opioidergic interactions supplemented by COX-2 and 5-LOX enzyme inhibition in addition to reducing pro-inflammatory cytokine expression. CHD may therefore possess potentially beneficial therapeutic effectiveness in the management of inflammation and pain

A mixed methods study to assess the effectiveness of food-based interventions to prevent stunting among children under-five years in districts Thatta and Sujawal, Sindh province, Pakistan: study protocol

Background: Maternal and child malnutrition is widely prevalent in low and middle income countries. In Pakistan, widespread food insecurity and malnutrition are the main contributors to poor health, low survival rates and the loss of human capital development. The nutritional status trends among children exhibit a continuous deteriorating with rates of malnutrition exceeding the WHO critical threshold. With the high prevalence of maternal and child malnutrition, it is important to identify effective preventative approaches, especially for reducing stunting in children under-five years of age. The primary aim of this study is to assess the effectiveness of food-based interventions to prevent stunting in children under-five years. Methods: A mixed methods study design will be conducted to evaluate the effectiveness of food-based interventions to prevent stunting among children under-five years in districts Thatta and Sujawal, Sindh Province, Pakistan. The study will include cross sectional surveys, a community-based cluster randomized controlled trial and a process evaluation. The study participants will be pregnant women, lactating mothers and children under-five years. The cross-sectional surveys will be conducted with 7360 study participants at baseline and endline. For the randomized control trial, 5000 participants will be recruited and followed monthly for compliance of food-based supplements, dietary diversity, pregnancy outcomes, and maternal and child morbidity and mortality. Anthropometric measurements and hemoglobin levels will be measured at baseline, quarterly and at endline. The interventions will consist of locally produced lipid-based nutrient supplement (Wawamum) for children 6–23 months, micronutrient powders for children 24–59 months, and wheat soya blends for pregnant and lactating mothers. Government lady health workers will deliver interventions to participants. The effectiveness of the project will be measured in terms of the impact of the proposed interventions on stunting, nutritional status, micronutrient deficiencies, and other key indicators of the participants. The process evaluation will assess the acceptability, feasibility and potential barriers of project implementation through focus group discussions, key informant interviews and household surveys. Data analysis will be conducted using STATA version 12. Discussion: There is considerable evidence on the effectiveness of food-based interventions in managing stunting in developing countries. However, these studies do not account for the local environmental factors and widespread nutrient deficiencies in Pakistan. These studies are often conducted in controlled environments, where the results cannot be generalized to programs operating under field conditions. The findings of this study will provide sufficient evidence to develop policies and programs aimed to prevent stunting in children 6–59 months and to improve maternal and child health and growth outcomes in poor resource setting

Effectiveness of unconditional cash transfers combined with lipid-based nutrient supplement and/or behavior change communication to prevent stunting among children in Pakistan: A cluster randomized controlled trial

Background: In Pakistan, the prevalence of stunting among children under-five years has remained above WHO critical thresholds (≥30%) over the last two decades.Objective: We hypothesized that an unconditional cash transfer (UCT) combined with lipid-based nutrient supplement (LNS) and/or social and behavior change communication (SBCC) will prevent stunting among children 6-23 months of age.Design: This was a four-arm, community-based cluster randomized controlled trial conducted in the district of Rahim Yar Khan, Pakistan. A total of 1729 children (UCT n = 434); (UCT+SBCC n = 433); (UCT+LNS n = 430) and (UCT+LNS+SBCC n = 432) were enrolled at 6 months of age and measured monthly for 18 months until the age of 24 months.Results: At 24 months of age, children who received UCT+LNS (rate ratio [RR], 0.85 [95% CI 0.74, 0.97]; P = 0.015); and UCT+LNS+SBCC (RR, 0.86 [95% CI 0.77, 0.96]; P = 0.007) had significantly lower risk of being stunted as compared to the UCT arm. No significant difference was noted among children who received UCT+SBCC (RR, 1.03 [95% CI 0.91, 1.16]; P = 0.675) in the risk of being stunted as compared to the UCT arm. The pooled prevalence of stunting among children 6-23 months was 41.7%, 44.8%, 38.5% and 39.3% in UCT, UCT+SBCC, UCT+LNS and UCT+LNS+SBCC, respectively. In pairwise comparisons, a significant impact on stunting among children in UCT+LNS (P = 0.029) and UCT+LNS+SBCC (P = \u3c0.001) was noted as compared to UCT arm.Conclusions: UCT combined with LNS and UCT+LNS+SBCC were effective in reducing the prevalence of stunting among children aged 6-23 months in marginalized populations. UCT+SBCC was not effective in reducing the child stunting prevalence.Clinical trial registration number: ClinicalTrials.gov NCT03299218

Specialized nutritious food combined with cash transfers and social and behavior change communication to prevent stunting among children aged 6 to 23 months in Pakistan: Protocol for a cluster randomized controlled trial

Background: In Pakistan, the prevalence of stunting in children younger than 5 years has remained above global critical levels over the past two decades, with the stunting rate being 40.2% in 2018. Children living in rural areas and in the poorest households suffer the most from stunting across the country-43.2% in rural areas and 51.4% in the lowest wealth quintile. As a continuing public health concern, it is essential that stunting prevention is a national priority in order to ensure human capital development, especially among the poorest households.Objective: The primary objective of this study is to determine the effect of a medium quantity of a lipid-based nutrient supplement (LNS) combined with unconditional cash transfers and social and behavior change communication (SBCC) on reduction of stunting in children aged 6 to 23 months.Methods: A 5-arm cluster randomized controlled trial will be conducted in the district of Rahim Yar Khan in Punjab, Pakistan. The intervention packages will be (1) cash only, (2) cash with LNS, (3) cash with SBCC, and (4) cash with SBCC and LNS. The control arm will receive routine standard of care. We will enroll children at 6 months of age and follow up on a monthly basis up to 24 months of age. A total of 2000 children, 400 in each arm, will be enrolled to detect a 20% reduction in the prevalence of stunting among children aged 24 months. Length, weight, food intake, compliance to interventions, morbidities, and other relevant data will be collected at enrollment and on a monthly basis over the period of 18 months. The process evaluation will assess acceptability of the interventions and potential barriers to implementation through focus group discussions and in-depth interviews with the target population and relevant stakeholders. Furthermore, a cost analysis will be conducted to assess the cost-effectiveness of each intervention package.Results: The study protocol was approved by the Ethics Review Committee of Aga Khan University in Pakistan on January 4, 2017. Data collection began in May 2017 and was completed in July 2019. Data analyses are yet to be completed. This study will explore the effectiveness of intervention packages comprised of cash transfers from Benazir Income Support Programme with or without additional LNS and SBCC in preventing childhood stunting. We expect the results to be published in peer-reviewed journals by autumn of 2020.Conclusions: The findings of this trial will provide robust evidence as to which intervention packages can have significant effects on linear growth of children and design effective intervention packages to prevent stunting in children aged 6 to 23 months

A green nutraceutical study of antioxidants extraction in Cleome brachycarpa - an ethnomedicinal plant

In the present study, an indigenous medical plant ‘Cleome brachycarpa’ was comparatively investigated for its antioxidant extraction for first time; using the soxhlet (traditional), microwave-assisted, and ultrasound-assisted (green) extraction methods with seven different solvents. The microwave-assisted extraction with methanol as solvent recovered the phytochemicals two-folds higher than the other methods with extraction efficiency of 370.57 ± 0.49 μg/ mg and correspondingly extracted the polyphenols: Phenolics (74.17 ± 0.61 μg GAE/mg DW), Flavonoids (65.46 ± 0.40 μg QE/mg DW), and Tannins (55.97 ± 0.85 μg CE/mg DW). The antioxidant capacity in relation with polyphenols was determined for Free radical scavenging activity and total antioxidant potential. The DPPH radical scavenging percentage of methanolic green extract of Cleome brachycarpa was found to be 81.37 ± 0.28 with IC50 of 0.30 mg/mL that matched up to the DPPH scavenging potential of Trolox. Furthermore, the ferric reducing potential was high up to 15.30 ± 0.30 μg GAE/mg DW. The correlation of antioxidant capacity with polyphenols was highly significant (p < 0.05). The green nutraceutical study has validated the ethnomedicinal importance of Cleome brachycarpa which is related to its high polyphenolic content. The findings highlight Cleome brachycarpa as a potential candidate for research and isolation of medicinal polyphenols
