Role of Social Commerce Forums in Establishing Purchase Intention: A Nexus Between Credibility, Trust and E-Commerce Satisfaction

Social media is persuading to consumers in field of social commerce (S-Commerce) by providing goods or services and fulfill their demands in a very short period of time. Electronic-satisfaction (e-satisfaction) and credibility have distinctive activities of social media that motivate and successively build the trust at various stages of purchase intentions. For better understanding it is necessary to recognize the factors of social commerce such as referrals, reviews & ratings because they have a strong influence on buying behaviour of ecommerce consumers. A quantitative and descriptive approach has been projected through simple random sampling. A cross-sectional data of 250 participants were collected by a survey questionnaire from social commerce users examined through Partial Least Square- Structural Educational Modeling-3 (PLS-SEM-3). A social support theory has supported relationship on trust through social media activities, surface credibility, and presumedcredibility as well as e-commerce satisfaction. Interestingly trust, surface and presumed credibility considerably significant impact on e-commerce and social commerce satisfaction that leads to develop purchase intention. The current study theoretically contributes novel indicator, presumed credibility in the social commerce industry and practically it promotes specific websites that triggers trust

Association of Serum PSA Levels with Histopathological Pattern of Prostate Lesions

Background: Pathological changes that mainly affect prostate gland are prostatitis, benign prostatic hyperplasia (BPH) and cancerous lesions. Digital rectal examination (DRE), Transrectal Ultrasonography (TUS), and prostate specific antigen (PSA) followed by histopathological examination, are routinely used tests for diagnosis of prostate lesions. The aim of the present study is to determine the role of serum PSA levels in differentially diagnosing the different types of prostate lesions.Material and Methods: This retrospective (observational) study was conducted in Ibn-e-Sina Hospital Multan. Data of 2189 patients who were operated from 2007 to 2017 due to prostatic lesions were included in this analysis. Patients with BPH, prostatitis, prostate carcinoma and Prostatic Intraepithelial Neoplasia (PIN) were grouped according to serum PSA levels (ranging from 0 to >100 ng/ml) into five groups. Frequencies and percentages were calculated for different histopathological findings. Association of PSA levels with different histological patterns was determined with chi-square test with P-value < 0.05 taken as significant difference.Results: Mean age of patients was 62.45+10.64 years. On histopathology, BPH was diagnosed in 1676 (76.56%) patients, prostatitis in 133 (6.07%), carcinoma in 378 (17.26%) and PIN in 02 (0.09%) patients, respectively. Serum PSA levels of 4.01-10 ng/ml were found in 1050 (62.64%) BPH patients and in 59 (44.36%) prostatitis patients. Serum PSA levels of 10.01-20 ng/ml were found in only 40 (2.4%) BPH patients, 47 (35.33%) prostatitis patients, 22 (5.82%) carcinoma patients and in 1 (50.0%) PIN patient. Serum PSA levels of 20.01-100 ng/ml were found in 32 (1.9%) BPH patients, 11 (8.27%) prostatitis patients, 302 (79.89%) carcinoma patients, and in 1 (50.0%) PIN patient. Serum PSA levels of >100 ng/ml were absent in patients with BPH and PIN, and present in 1 (0.75%) prostatitis and 54 (14.28%) carcinoma patients.Conclusion: Benign prostatic hyperplasia was the commonest lesion in our patients (76.56%) with serum PSA levels >10 ng/ml reported in all patients with prostate carcinoma and prostatic intraepithelial neoplasia (PIN) patients

Confirmation of root-knot nematode resistant gene Rmi1 using SSR markers

Background: The Root Knot Nematode (RKN) is a serious economic threat to various cultivated crops worldwide. It is a devastating pest of soybean and responsible to cause severe yield loss in Pakistan. The cultivation of resistant soybean varieties against this pest is the sustainable strategy to manage the heavy loss and increase yield. There is an utmost need to identify RKN resistant varieties of soybean against cultivated in Pakistan. The presented study is an attempt to identify and confirm the presence of resistant gene Rmi1 in soybean. Method: Molecular studies have been done using Simple Sequence Repeat (SSR) marker system to identify resistant soybean varieties against Root Knot Nematode (RKN) using fifteen (15) indigenous cultivars and four (4) US cultivars. DNA was isolated, purified, quantified and then used to employ various SSR markers. The amplified product is observed using gel documentation system after electrophoresis.  Results: Diagnostic SSR markers Satt-358 and Satt-492 have shown the presence of Rmi1 gene in all resistance carrying genotypes. Satt-358 amplified the fragment of 200 bp and Satt-492 generated 232 bp bands in all resistant genotypes. This study confirmed the Rmi gene locus (G248A-1) in all internationally confirmed resistant including six (6) native varieties.Conclusion: These investigations have identified six (6) resistant cultivars revealing the effective and informative sources that can be utilized in breeding programs for the selection of RKN resistance soybean genotypes in Pakistan.

Mental and physical health correlates of the psychological impact of the first wave of COVID-19 among general population of Pakistan

The primary aim was to assess the role of mental and physical health of COVID-19 and its psychological impact in the general population of Pakistan during the first wave of COVID-19. It was hypothesized that there would be a significant predictive association among socio-demographic variables, psychological impact and mental health status resulting from COVID-19, and poor self-reported physical health would be significantly associated with adverse psychological impact and poor mental health status because of COVID-19. A cross-sectional survey research design was used in which 1,361 respondents were sampled online during lockdown imposed in the country. The Impact of Events Scale-Revised (IES-R) was used to assess the psychological impact of COVID-19, and the Depression Anxiety Stress Scales (DASS-21) was used to assess participants’ mental health status. 18% of the respondents reported moderate to severe event-specific distress, 22.6% reported moderate to severely extreme depression, 29% reported moderate to extreme anxiety, and 12.1% reported moderate to extreme stress. Female gender, having graduate-level education, currently studying, and self-reported physical symptoms (persistent fever, chills, headache, cough, breathing difficulty, dizziness, and sore throat) were significantly associated with higher levels of psychological impact exhibited through higher scores on the IES-R and poorer mental health status exhibited through higher scores on the DASS-21 (Depression, Anxiety, and Stress Subscales)

Reflection phenomena of waves through rotating elastic medium with micro-temperature effect

In this article, we analyzed the effect of variable thermal conductivity on reflected elastic waves. The waves are propagating through a thermoelastic medium rotating with some angular frequency. The concept of micro-temperature is also been considered, in which microelements of the medium contain a high temperature. A heat conduction phenomenon is encountered by dual phase-lag heat conduction model. P (or SV)-type wave is incident on the medium with some specific angle of incidence. After reflection from the surface incident, P-wave is converted into quasi longitudinal and quasi transverse waves and propagates back into the medium. Helmholtz’s potential function along with the harmonic wave solution is used to obtain the solution of the model. Analytically, we calculated the amplitude ratios and attenuation factor for each reflected wave against the angle of incidence. The obtained results are also represented graphically for different values of rotational frequency and variable thermal conductivity for a particular material

Belief and Possibility Belief Interval-Valued N-Soft Set and Their Applications in Multi-Attribute Decision-Making Problems

In this research article, we motivate and introduce the concept of possibility belief interval-valued N-soft sets. It has a great significance for enhancing the performance of decision-making procedures in many theories of uncertainty. The N-soft set theory is arising as an effective mathematical tool for dealing with precision and uncertainties more than the soft set theory. In this regard, we extend the concept of belief interval-valued soft set to possibility belief interval-valued N-soft set (by accumulating possibility and belief interval with N-soft set), and we also explain its practical calculations. To this objective, we defined related theoretical notions, for example, belief interval-valued N-soft set, possibility belief interval-valued N-soft set, their algebraic operations, and examined some of their fundamental properties. Furthermore, we developed two algorithms by using max-AND and min-OR operations of possibility belief interval-valued N-soft set for decision-making problems and also justify its applicability with numerical examples

Six-minute walk distance, ECOG Performance Status, and Modified Borg Scale scores in a cohort of Pakistani men and women with noncancerous end-stage liver disease selected for liver transplant

Objectives: To evaluate the functional status of Pakistani patients with non-cancerous end-stage liver disease selected for liver transplant, and to compare results acquired through various assessment tools. Methods: The study was conducted at the Rehabilitation Medicine Department, Shifa International Hospital, Islamabad, Pakistan, from August 2017 to November 2019, and comprised end-stage liver disease patients of either gender who had been selected for liver transplant.  Assessment tools included the Six-Minute Walk Distance, Eastern Cooperative Oncology Group Performance Status and Modified Borg Scale across age, gender, ethnicity, primary aetiology, and Model for end-stage liver disease scores. Data was analysed using SPSS 20. Results: Of the 172 patients, 143(83%) were males; 99(58%) hailed from the Punjab province; and 118(71%) had hepatitis C as the most common aetiology. The overall mean age was 46.1±10.5 years (range: 14–70 years). The mean Six-Minute Walk Distance was 291.9±67.2m. Model for end-stage liver disease scores had a significant inverse correlation with Six-Minute Walk Distance (p0.05). Conclusions: The Six-Minute Walk Distance score was significantly low.  The Model for end-stage liver disease scores were inversely correlated with Six-Minute Walk Distance scores, and positively correlated with Eastern Cooperative Oncology Group Performance Status and Modified Borg Scale scores.
