Pairwise Stability in Two Sided Market with Strictly Increasing Valuation Functions
This paper deals with two-sided matching market with two disjoint sets, i.e.
the set of buyers and the set of sellers. Each seller can trade with at most
with one buyer and vice versa. Money is transferred from sellers to buyers for
an indivisible goods that buyers own. Valuation functions, for participants of
both sides, are represented by strictly increasing functions with money
considered as discrete variable. An algorithm is devised to prove the existence
of stability for this model.Comment: 10 pages, no figure
Influence of Waste PET Bottle Particles and Steel Fibers on Fresh Properties of Concrete
Fiber-reinforced concrete containing wastes is trending nowadays due to its better performance and modified mechanical properties when compared to conventional concrete. Those wastes include artificial and natural fibers which are low density, lightweight, environment-friendly, and cost-friendly as well. Steel fibers along with waste PET (Polyethylene terephthalate) bottle particles with varying percentages are used to study the combined effect on concrete. Fresh properties of concrete strongly depend on the dynamic and mechanical properties of concrete. So, it is important to determine the fresh concrete’s workability for easy handling and pouring. The study aims to determine the effect of steel fibers and waste PET bottle particles with different percentages on the properties of fresh concrete. Pozzolanic material and admixture are used to enhance the workability of concrete. In this study, three combinations are made by keeping the constant percentage of steel fibers i.e. 2% by volume, and varying percentages of PET bottle particles. Plain concrete (PC) is designed for the strength of 30MPa and slump, fresh density, and compaction factor tests were conducted for examining the fresh concrete properties. The concrete’s workability is checked by doing a slump cone test, compaction factor test, and fresh density, then results are compared with PC. The results showed that by adding steel fibers (SFs) and washed PET bottle particles, the value of the slump decreased by 18.2% for the mixture containing 5% PET particles, 41% for the mixture containing 10% PET particles, and 59% for the mixture containing 15% PET particles when compared with PC
Mapping the Causal Connections among Exchange Rate Fluctuations and Agriculture Production: New Evidence from Pakistan Utilizing Cointegration Analysis
This study is the foreign exchange rate and export sector and impact on macroeconomics variables. The objective is to research the experiential association between the rate of exchange and the export sectors of Pakistan. The time series data has been used which covered 1980- 2020. In this study, we used three major sectors that have been selected for this research like the Agricultural sector as the dependent variable. Rate of exchange, foreign direct investment, rate of inflation, and interest rate are being used as explanatory variables in this study. For the long run and short run estimation among variables; we used the Auto regressive distributed lag model (ARDL). Likewise, Augmented Dickey Fuller (ADF) uses the estimation of the integration of order. According to long run findings of this study illustrated that model one, exchange rate is positive and significant. Foreign direct investment is both positive and significant, as is the money supply (M2). Trade openness is a positive and significant impact on agriculture.  
Assessment of asthma control using the asthma control test at a tertiary care centre in Karachi, Pakistan
The aim of our study was to assess asthma control among asthmatics at a tertiary care setting in Karachi using ACT questionnaire. The ACT questionnaire was filled by known asthmatics in January 2007. A total of 150 questionnaires were filled of which, 61 (40%) were males and 89 (60%) females. Mean ACT score was 17.71 +/- 4.41. Association between sex and asthma control was not statistically significant. Significant association was seen with asthma control and Ipratropium bromide inhaler. Asthma control among patients at a tertiary care centre is moderate. ACT can be used to follow patients in the hospital
Male rape, masculinities, and sexualities : understanding, policing, and overcoming male sexual victimisation
PhD ThesisThis qualitative project critically explores state and voluntary agencies’ attitudes
toward, and responses to male rape victims in England. It critically examines the ways
in which police officers, male rape counsellors, therapists, and voluntary agency
caseworkers (N = 70) think about and deal with male victims of rape. It pays close
attention to how notions of gender, sexualities and masculinities affect and shape state
and voluntary agencies’ understanding of male rape and their views of men as victims
of rape. Police cultures are also examined to understand how male rape is policed in
England. The data are grounded in sociological, cultural, and post-structural
theoretical frameworks, such as hegemonic masculinity and heteronormativity. The
data were collected through in-depth semi-structured interviews and qualitative
questionnaires. The qualitative data were analysed with the use of thematic analysis,
drawing out important themes and concepts of the ways in which male rape is thought
about, responded to, and dealt with by state and voluntary agencies. The research
contributes to existing knowledge on male rape by contributing theoretically to
discourse on unreported and unacknowledged sexual violence. Research on male rape
is lacking in England. The scarce literature on male rape predominately examines
male rape from either a clinical or psychological perspective, whereas this project
approaches male rape from a sociological, cultural and post-structural perspective to
fully understand this phenomenon. Providing state and voluntary agencies’ discourses
of male rape is important because they are the first port of call for male rape victims,
yet the existing body of knowledge predominantly focuses on the victims’
experiences of rape, although this is important. It is also vital, though, to make sense
of the experiences and perspectives of state and voluntary agencies because they work
very closely with male rape victims. I argue that cultures, social relations, power and
discourses shape how state and voluntary agencies understand and respond to male
rape. Through social structures, social practices, and social institutions, state and
voluntary agencies consider and respond to male rape inconsistently, which can have
serious implications for policy and practice as this project carefully details
