Structural Changes in Radio and Impacts on Music Listeners

The current study explores structural changes in radio and assesses their impact on music listeners in Pakistan utilizing the theoretical underpinnings of the political economy of communication. A mixed-method approach was used to answer research questions and evaluate hypotheses. A contextual analysis was utilized to evaluate the qualitative analysis after the interviews with 14 experts in the Pakistani radio industry were transcribed. Cross-tabulation with chi-square test, Independent Sample T-test, and AVOVA with Tukey tests were used to analyze survey responses from 200 respondents in order to determine the correlations between variables. The findings show that structural trends in the radio industry\u27s deregulation and commercialization have curtailed access to a varied range of listeners in Pakistan. According to the research, deregulation, licensing fees, new license fees, and the restriction of Indian music, revenue generation, and licensing to nonprofit FM radio have all limited access to a diverse spectrum of radio music listeners in Pakistan. This trend also leads broadcast media in Pakistan to produce and disseminate more entertainment programming rather than information and education programs

Common fixed point theorem for modified Kannan enriched contraction pair in Banach spaces and its applications

The purpose of this paper is to introduce the class of (a; b; c)-modified enriched Kannan pair of mappings (T; S) in the setting of Banach space that includes enriched Kannan mappings, contraction and nonexpansive mappings and some other mappings. Some examples are presented to support the concepts introduced herein. We establish the existence of common fixed point of the such pair. We also show that the common fixed point problem studied herein is well posed. A convergence theorem for the Krasnoselskij iteration is used to approximate fixed points of the (a; b; c)-modified enriched Kannan pair. As an application of the results proved in this paper, the existence of a solution of integral equations is established. The presented results improve, unify and generalize many known results in the literature.http://www.pmf.ni.ac.rs/filomatam2022Mathematics and Applied Mathematic

Influence of Lifestyle and Cultural Values on Impulse Buying Behavior

The aim of research is to analyze the influence of life styles and cultural values on the impulse buying behavior of Pakistani university students and professionals in different organizations.  For collection of data, survey technique was used from the students of different universities and organizations by adopting the convenient sampling technique.  For analyzing the group differences between the variables of lifestyles and cultural values on impulse buying behavior, it was found that only gender role has the significant differences between male and female students and professionals on the impulse buying behavior. For analyzing the relationships among the variables of life style and cultural values, it was found that significant relationship exists among all the variables.  The study also shows that variables of life style and cultural values such as, life satisfaction, security, financial satisfaction, gender role and in-group contact predict the influence on impulse buying behavior of the Pakistani students and professionals. Keywords: Cultural values, Impulse buying behavior, Financial satisfactio

Determinants of academic stress and stress-related selfmedication practice among undergraduate male pharmacy and medical students of a tertiary educational institution in Saudi Arabia

Purpose: To identify factors that promote academic stress and stress-related self-medication practice among undergraduate male students of pharmacy and medical colleges at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Methods: A cross-sectional survey was conducted among undergraduate students of pharmacy and medical colleges of the university. The study used Perceived Stress Scale (PSS) to document academic stress. The responses of the students were analyzed using SPSS version 22. Results: As many as 51.6 % of students’ perceived moderate stress. The majority of students (55.9 %) highlighted examination as a stressor followed by course load (43.2 %) and cGPA (40.4 %). Prevalence of self-medication was 31.58 and 29.20 % among pharmacy and medical students, respectively. Most of the students consumed caffeine (63.8 %) and nicotine (17.8 %) as a drug. Students blamed heavy course load (23.9 %), followed by assignment load (23 %) and examination (21.1 %) for indulging in self-medication. Conclusion: Academic stress in undergraduate students in health disciplines is perceived to be high by the students. Examinations, course load and lack of time for leisure are major determinants of stress. Caffeine and nicotine are most frequently used by a majority of the students for self-medication. Keywords: Stress, Self-medication, Stressor, Caffeine, Nicotine, Student

A note on the fixed point theorem of F-contraction mappings in rectangular M-metric space

In this note, we show that the main result (Theorem 3.2) due to Asim et al. (Appl. Gen. Topol., 23(2), 363-376 (2022) https://doi.org/10.4995/agt.2022.17418) is still valid if we remove the assumption of continuity of the mapping

Willingness to pay for vaccination against hepatitis b and its determinants: the case study of an industrial district of Pakistan

Willingness to pay (WTP) for vaccination of hepatitis disease is a good measure to monetize the physical effects of a disease into monetary values. Therefore, the present study aims to find the willingness to pay for self-paid vaccines for hepatitis and its determinants in an industrial district Faisalabad, Pakistan. Primary data was collected from 200 nonpatients of hepatitis which were personally interviewed by using convenient sampling method. A scenario was presented to the selected respondents by using CVM technique. The respondents were randomly assigned to pre-chosen payment bids defined on the basis of prevailing market rates for vaccination at the time of survey. The multivariate linear regression was used to find the determinants of WTP. The results show that females are slightly more willing to pay as compared to males. The variables like age, income and awareness about hepatitis have positive impact on WTP for vaccination of hepatitis disease. About 57.3 percent people belonging to low income group wanted vaccination free of cost in Pakistan.Government should launch free vaccination programs for the most vulnerable group (poor) and must launch awareness campaign to increase knowledge about disease

An Insight into Different Strategies for Control and Prophylaxis of Fasciolosis: A Review

Fasciolosis is one of the important diseases of livestock and has zoonotic importance. Fasciolosis can cause huge economic losses due to decrease in milk and meat production, decreased feed conversion ratio, and cost of treatment. Treatment and prophylaxis strategies for Fasciola infection are formed based on epidemiological data. The control of Fasciola infection can be attained by treating the animals with active anthelmintics. The use of different combinations of anthelmintics with a possible rotation is more effective against immature as well as adult flukes. Control of the intermediate host (snail) is vital for the reduction of fasciolosis. Due to the rapid growth of snails, the eradication is quite difficult in waterlogged and marshy areas. The use of different grazing methods and treatment of grazing areas can also help to control fasciolosis. A variety of antigens generated by Fasciola spp. have been shown to protect against liver fluke infection. The crude antigens, excretory/secretory, and refined antigens and their combination can be used as prophylactic treatment for the control of fasciolosis. The use of any of the single or combination of these methods can be very effective for the control of fasciolosis

Analysis of cervical smears in a muslim population

Background: Screening for cancer of the cervix remains a neglected health care issue in Pakistan. To provide baseline data for future efforts to improve screening, we conducted a retrospective analysis of cervical smears taken in the obstetrics and gynaecological clinics of the Aga Khan University Hospital, Karachi, Pakistan.Method: We collected data on cervical smear cytology for cervical smears taken from January 1, 1990 to December 31,1996. We assessed risk factors for dysplasia, including age, age at first marriage, and number of pregnancies.Results: The overall prevalence of abnormal smears in our study was 0.5%. Of 20,995 cervical smears, 12,451 (59.3%) smears showed non-specific inflammation, 7302 (34.8%) were reported as normal, 809 (3.85%) showed monillial infection, 148 (0.71%) showed atypia, 105 (0.5%) had dysplastic cytology, and 52 (0.25%) samples were inadequate. The highest incidence of dysplastic smears was seen in the age group 35 to 44 years. Of 105 patients with dysplasia, 12 were pregnant, and all were asymptomatic, while in 93 non-pregnant women, 33 were symptomatic.Conclusion: The low prevalence of abnormal smears, compared with data from Western populations, could be due to the inherent bias of health awareness in the women who attended our hospital. The results of this study may serve as a baseline for future comparisons. A larger community-based study may establish the exact prevalence of malignant and premalignant lesions so as to plan for future screening

Genetic Confirmation of Mungbean (Vigna radiata) and Mashbean (Vigna mungo) Interspecific Recombinants using Molecular Markers

The present study was conducted with the aim to investigate recombination between mungbean (female) and mashbean (male) interspecific crosses using molecular markers i.e., URP (Universal Rice Primers), RAPD (Random Amplified Polymorphic DNA) and SSR (Simple Sequence Repeats). As a first step parental screening was performed and polymorphic markers differentiating parent genotypes were identified. Recombinations were then confirmed through polymorphic DNA markers in many of the hybrids. The NM 2006 × Mash 88 was found to be most successful interspecific cross as many of true recombinants, confirmed by molecular markers, belonged to this cross combination. The SSR markers were more efficient in detecting genetic variability and recombinations with reference to specific chromosomes and particular loci, while SSR (RIS) and RAPD identified variability dispersed throughout the genome. The DNA based marker assisted approach provided evidence for genetic confirmation of mungbean and mashbean interspecific recombinants and escalated the authenticity of selection in mungbean improvement programme
