<p class="JARTEAbstractHeader">The purpose of this empirical research was to analyze the comfortable waiting time (CWT) of patients at the outpatient department (OPD) of Gastrology of ABC hospital of Karachi. It is based on the analysis of CWT of patients who were being served at the OPD of Gastrology of ABC hospital of Karachi. The data was collected by the help of questionnaire. Altogether 250 questionnaires were distributed among the patients, 210 of them were collected back and 10 of them were incompletely filled. Data was analysed in the statistical package for social sciences (SPSS) version 22. Data analysis included frequency distribution of various demographics;stratification tables were made for the comparison of CWT across various demographics. Results indicated that more females (old aged) had greater CWT in the comparison of males. It is found that the mean CWT of patients decreased with decreasing age, increasing OPD visiting time and increasing income. It is also found that he mean CWT for the patients from Afghanistan was greater than the patients from other regions i.e. Baluchistan, interior Sindh and Karachi. The authors highlighted that when patients arrive at the hospital and wait for their service, in this scenario, waiting cost is associated with their waiting time; since it is the matter of cost, thus it should be known to the hospital that if patients are made to wait longer, it can lead to the customer dissatisfaction. In this regard, analysis of comfortable waiting time of patients was extremely needed. Since, Karachi is the biggest city of Pakistan and targeted hospital is one the biggest private hospitals of Karachi and in the analysis of this paper. Only 200 patients were approached for data collection which is the main limitation of the paper. In future, the researchers should also focus on the same OPD for more responses and at the same time, other departments can also be targeted for conclude better and precise results. The authors have tried to focus on the CWT of patients so that the waiting capacity of patients could be highlighted. At the same time, detailed analysis was conducted across demographics so that their influence on CWT could be analysed.</p><p class="JARTEKeywords"> </p>

Currently, the hostel life is so necessary for the students. During their higher studies, the students face a lot of problems of accommodation. After the solution of accommodation, the students face the issues in the hostels regarding their provided services. The data of students’ feedback is gathered from the Director MIS, MUET, Jamshoro by taking the sample of 60 students from each boy’s hostel. For analysis, we use the tool Statistical Package for Social Sciences (SPSS V.16). This study revealed the analysis of two services, water supply and first aid in the seven boy’s hostels of MUET, Jamshoro. The null hypothesis is accepted for all hostels except Rashidi, Hyder Bux Jatoi and Shah Abdul Latif. These results determined the strong relationship between the services water supply and first aid. From this study, we suggest to authorities of the university management to provide the necessary betterment regarding the water supply and first aid facilities in Rashidi, Hyder Bux Jatoi and Shah Abdul Latif hostels.

Research on human-environment interactions often neglects the resources of the humanities. Hurricane Katrina and the resulting levee breaches in New Orleans offer a case study on the need for inclusion of the humanities in the study of human-environment interactions, particularly the resources they provide in examining ethics and value concerns. Methods from the humanities, when developed in partnership with those from the sciences and social sciences, can provide a more accurate, effective, and just response to the scientific and technological challenges we face as a global community.

This essay explores the theory of intersectionality in the study of youths’ lives and social inequality in the Global South. It begins with an overview of the concept of intersectionality and its wide applications in social sciences, followed by a proposal for regrounding the concept in the political economic systems in particular contexts (without assuming the universality of capitalist social relations in Northern societies), rather than positional identities. These systems lay material foundations, shaping the multiple forms of deprivation and precarity in which Southern youth are embedded. A case study of rural migrant youths’ ‘mobility trap’ in urban China is used to illustrate how layers of social institutions and structures in the country’s transition to a mixed economy intersect to influence migrant youths’ aspirations and life chances. The essay concludes with ruminations on the theoretical and social implications of the political-economy-grounded intersectionality approach for youth studies.

AbstractSustainable development of container terminals is based on energy efficiency and reduction in CO2 emissions. This study estimated the energy consumption and CO2 emissions in container terminals according to their layouts. Energy consumption was calculated based on utility data as well as fuel and electricity consumptions for each container-handling equipment in the container terminal. CO2 emissions were estimated using movement modality based on the number of movements of and distance travelled by each container-handling equipment. A case study involving two types of container terminal layouts i.e. parallel and perpendicular layouts, was conducted. The contributions of each container-handling equipment to the energy consumption and CO2 emissions were estimated and evaluated using statistical analysis. The results of the case study indicated that on the CO2 emissions in parallel and perpendicular layouts were relatively similar (within the range of 16–19 kg/TEUs). These results indicate that both parallel and perpendicular layouts are suitable for future ports based on sustainable development. The results can also be used for future planning of operating patterns and layout selection in container terminals.

Third Moment

In order to understand queueing performance given only partial information about the model, we propose determining intervals of likely values of performance measures given that limited information. We illustrate this approach for the mean steady-state waiting time in the $GI/GI/K$ queue. We start by specifying the first two moments of the interarrival-time and service-time distributions, and then consider additional information about these underlying distributions, in particular, a third moment and a Laplace transform value. As a theoretical basis, we apply extremal models yielding tight upper and lower bounds on the asymptotic decay rate of the steady-state waiting-time tail probability. We illustrate by constructing the theoretically justified intervals of values for the decay rate and the associated heuristically determined interval of values for the mean waiting times. Without extra information, the extremal models involve two-point distributions, which yield a wide range for the mean. Adding constraints on the third moment and a transform value produces three-point extremal distributions, which significantly reduce the range, producing practical levels of accuracy.

Research Perspectives

Some of the constructs in the field of performance management are intuitive or not empirically validated. This study provides a data-driven framework for measuring and improving the performance through synchronized strategies. The ultimate goal was to provide support for increasing business performance. Empirical research materializes in an exploratory case study and a statistical analysis with econometric models. The case study revealed that a company can improve its performance, even in periods of growth, being characterized by consistent investments. The statistical analysis, performed on a restricted sample of companies, confirmed the results that were provided by the case study. The measurement of performance was made by capitalizing on financial and non-financial data precisely to intensify the interest for corporate sustainability. The obtained results, contrary to previous research that showed that economic value added (EVA) is negatively influenced by the increase in invested capital, open up new research perspectives to find out whether, at the industry level, performance appraisal that is based on EVA stimulates the development of a business’s economic capital. The research has a double utility: scientific (by providing an overview of the state of the art in the field of performance management) and practical (by providing a reference model for measuring and monitoring performance).
