Existence of fixed points of large MR-Kannan contractions in Banach Spaces
No full text[EN] The purpose of this paper is to introduce the class of large MR-Kannan contractions on Banach space that contains the classes of Kannan, enriched Kannan, large Kannan, MR-Kannan contractions and some other classes of nonlinear operators. Some examples are presented to support the concepts introduced herein. We prove the existence of a unique fixed point for such a class of operators in Banach spaces.Anjum, R.;Abbas, M.;Waqar Akram, M.;Radenovic, S. (2024).

Study on the Socioeconomic Factors Affecting Adoption of Agricultural Machinery
No full textIn the context of south Asia, There is enough support for suitable agricultural machinery for small farmers. These kind of agricultural machineries can improve the return of investment in land and labor, although large capital investments are still required that can impede ownership. The growing demand for machinery has resulted in comparatively more developed rental marketplaces for irrigation, tillage and other post-harvest procedures. Numerous small businesses are therefore accepting access to farm machinery that would otherwise be incredibly expensive to buy through service fee arrangements, although there is still room for expansion. In order to facilitate the advancement and investment of such machinery more effectively, it is necessary to better understand the associated factors with the purchase of agricultural machinery and the provision of services. Firstly, current paper reviews country’s policy structure which enabled the existence of such machinery markets. It then uses stratified random sample of 305 wheat producing households for the survey from six districts, identifying variables associated with the adoption of the most common smallholder agricultural machinery e irrigation pumps, threshers, and power tillers. Results of multinomial probit model show that education of farmer, member of farmer’ organization, livestock ownership, farm size and being part of non-farm work activities all were significantly positive in the adoption of farm machinery. Findings also suggest that institutions and policy making authorities not only need to focus on short projects to encourage adoption of machinery, also there must be a continuous attention to improve physical and civilian infrastructure & services, and ensuring the availability of credit to create an favorable conditions where agricultural machinery is most likely to be used.

Technical Efficiency Analysis of Wheat Farms in the Punjab, Pakistan: DEA Approach
No full textThe wheat productivity in the Punjab is less than the potential maximum due to technical farm and management issues. The farm level panel survey data was used for the said purpose comprising 17 districts of the province of the Punjab from the period 2005-06 to 2007-08. The technical efficiency of wheat farms was analyzed using Data Envelopment Analysis (DEA) approach. Subsequently, the same was calculated by analyzing the socioeconomic factors responsible for (in) efficiency using Tobit Regression Model. The DEA didn’t accommodate statistical noise such as random shocks which were beyond the control of farmers. However, the technical efficiency of wheat farms was estimated using the DEA approach. The mean technical efficiency estimated through variable return to scale (VRS) was 60.13 percent and constant return to scale (CRS) was 56.61 percent. The results of analyses were supported by the literature. The technical efficiency could be improved by educating the young farmers, building road infrastructure and providing access to essential inputs to farmers. The study undertaken supports the argument that technically wheat farmers are less efficient in the Punjab, Pakistan
Emotional Intelligence and Personal Development in Employees: A Case Study of Zigron Corporation, Pakistan
No full textArticle sought to explore the potential role of Emotional Intelligence (EI) in the personal development of organizational employees and to find out the scope of emotional intelligence for personal development of individuals. This study was qualitative in nature; however, to ensure the authenticity and generalizability of the results some quantitative analysis analyses were applied. Using case study method and taking interviews from 17 software house engineers of Zigron Corporation in Pakistan, this study suggests that emotional intelligence plays a crucial role in the personal development of individuals
Occupational Gender Segregation and Its Determinants, an Analysis of Pakistan Labor Force Market
No full text3D finite element analysis of tine cultivator and soil deformation
No full textFor effective tillage, design and selection of tillage tool according to soil type and condition is very important. The present study is carried out for in-depth investigation of different types of shovels of tine cultivator and behavior of soil in response to loads subjected during tillage using finite element analysis. Different types of shovels like reversible, duck foot, seed drill and cultivator shovel are simulated with different types of soil like sand, clay and loam. The origination, level and distribution of stresses and deformations in shovels experienced in different types of soils are probed. Furthermore, high stressed and crack sensitive regions are identified. The stresses of 18, 53, 64 MPa are generated in reversible shovel of tine cultivator during ploughing in sandy, clay and loamy soil respectively. In addition, results of different shovels are compared, and it is found that the duck foot type shovel experiences highest stress and deformation. The duck foot shovel experiences about 20 and 71% higher stresses in loam compared to that in clay and sand respectively. Moreover, the study of soil mechanical behavior shows that the soil block (clay soil) experiences maximum stress of 34 MPa while tilling with reversible shovel. The statistical analysis is also conducted that shows high significance of simulation results
Applications to Solving Variational Inequality Problems via MR-Kannan Type Interpolative Contractions
No full textThe aim of this paper is manifold. We first define the new class of operators called MR-Kannan interpolative type contractions, which includes the Kannan, enriched Kannan, interpolative Kannan type, and enriched interpolative Kannan type operators. Secondly, we prove the existence of a unique fixed point for this class of operators. Thirdly, we study Ulam-Hyers stability, well-posedness, and periodic point properties. Finally, an application of the main results to the variational inequality problem is given
What factors can help COVID-19 patients to recover quickly in Pakistan
No full textThe research paper uncovers the socioeconomic factors which are associated with the recovery of coronavirus in Pakistan. Using a self-designed questionnaire, we collected the data from 170 corona recovered patients and applied Multiple linear regression to predict the effect of socioeconomic factors. The paper finds that patients aged between 36 and 46 years take around 3 more days to recover, whereas, patients aged above than 46 years take around 7 more days to recover in comparison to the young adults (17-25 years). In addition, patients who live in urban areas recover almost 1.5 days earlier than those who live in rural areas. Patients who have other serious diseases take almost 1.7 more days to recover in comparison to those who do not have any disease. Patients who smoke take 2 more days to recover in comparison to those who do not smoke. Moreover, obese people take almost 2.6 more days to recover in comparison to those who have a normal body mass index. Surprisingly, income, gender, and education remain insignificant in relation to the recovery days. We suggest, people above 46 should be given extra care, policies regarding smoking cessation, and lowering obesity should be implemented to combat coronavirus
Does Land Tenure Systems Affect Sustainable Agricultural Development?
No full textThe current study aims to investigate the agricultural investment differences among three kinds of land lease agreements and their effect on farmers’ decisions regarding sustainable growth in terms of soil conservation and wheat productivity, using cross-sectional data from rural households in Punjab, Pakistan. The “multivariate Tobit model” was used for the empirical analysis because it considers the possible substitution of investment choices and the tenancy status’ endogeneity. Compared to agricultural lands on lease contracts, landowners involved in agribusiness are more likely to invest in measures to improve soil and increase productivity. Moreover, the present study has also identified that the yield per hectare is much higher for landowners than sharecroppers, and thus, the Marshall’s assumption of low efficiency of tenants under sharecroppers is supported
