In today’s era of technological competitiveness, the world has witnessed an unprecedented enhancement and technological expansion in electronic market. This tough competition has made it really difficult for the firms to survive without introducing technological modifications within existing business processes and structure. Therefore, it was wise enough for the companies across the globe to invest huge part of their capital in launching web-based systems, thus making sure that more users are involved and have access to the systems globally. Nevertheless, the key factors that play the most vital role in making such systems successful, is solely the will of users as to much extent they are comfortable using these systems. If users are not willing to fully utilize given systems then this will not help firms to generate revenue on their investment. It was therefore necessary to systematically understand users’ decision making process towards acceptance of such systems. In this regard this research was aimed to design and develop a framework of influential factors that were expected to improve efficiency, acceptability and usage of web-based transactional systems. The model developed in this study was based on well-established technology acceptance model. Despite the popularity of technology acceptance model, there was not a single study, as per author’s knowledge, that has studied and extended it from usability perspective. Although usability has been considered in prior work as a dominant factor for success of the system. Little efforts, however, were devoted to the fundamental issues such as what specific usability characteristics are expected to have an impact on users’ acceptance behaviour or how the acceptance or usage of such systems would be influenced by usability features. This is so because if usability related dimensions/factors are indeed confirmed to show an effect on users’ decision behaviour, online vendors and their design team would be able to focus on those specific dimensions and to positively motivate users towards such systems’ acceptance and usage.

پاکستان کے مشترکہ خاندانی نظام میں رہائش سے متعلقہ مسائل اور ان کا حل (اسلامی تعلیمات کی روشنی میں ایک جائزہ) Issues of Accommodation in the joint family system of Pakistan and their solution (An analytical study in the context of the Islamic teachings)

A family is the fundamental unit of society. Every society has the presence of a family. The start of a family's life is entirely dependent on matters of co. human relations. All such human relationships are entrenched in islamic sharia as a sacred bond of nikah, in which a husband and wife become a part of the world in the form of a family's collective result. Husband and wife are the most fundamental pillars of society, and their affection and companionship provides a source of stability for them and also a refuge for coming generations.A  family consist of husband ,wife and their children . The family life is begins with marriage, after marriage every woman wants to have her own separate home where all the requirements of privacy are met. Islam has placed the entire responsibility of livelihood on men..But in our society there are two types of family system joint and separate family system. In Pakistan The joint family system is prevalent. The people of the subcontinent are not only adopting this system but they are  also feel proud of it . In the present article the joint family  system has facing many challenges. One of them is accommodation. In this article will focus on  what is the basic concept of accommodation in joint family systems and its solution in Islami teachings. It is critical for the husband and wife to have a home where no one can  interfere on their personal matters. This interference is very much in our society.Which husband and wife facing many  problems. And due to this conditions, the relationship of husband and wife is also affected. Key Words: Joint family system, Issues of Accommodation, Pakistani society, Islamic teachings.

Assessment of Forage Productivity and Livestockwildlife Competition over Utilization of Alpine Pastures in Hushe and Thallay Valleys of Baltistan

The present study was conducted to assess the vegetation cover, productivity, carrying capacity in the alpine rangelands of Gilgit-Baltistan. The assessment of the population of domestic ungulates, wild ungulates and their habitat characteristics was also carried out. At the end the diet composition and diet selection of wild ungulates and domestic small ruminants for important fodder resources were assessed, so that the severity of grazing pressures on these rangelands could be assessed. A model was developed in the area of competition keeping in view the availability and preferences of livestock and wild ungulates for the future sustainable use of rangeland resources. The study was conducted during July and August of 2012-13; diet competition was assessed during the winter season of the same year. The line transect method was used to assess the cover and productivity of rangelands. A total of 1320 quadrats were selected in both the Hushe and Thallay valleys in 2012 and 2013. Cover abundance of the individual species within each quadrat was measured and recorded. The vegetation cover was higher in Thallay Valley, showing coverage over 60% area, while the Hushe Valley showed 36% area covered by vegetation, however, the productivity of the Hushe range was relatively higher (275.5 Kg/ha) than in the Thallay Valley (240.5 Kg/ha). Within the vegetation cover distribution, the Hushe range was mainly dominated by forb (22.38%); the Thallay Valley was also dominated with forb (25.42%), in which Artemisia was dominant. This means the palatable species has been replaced by less palatable and drought resistant species due to the combined effect of overgrazing and environmental factors. In Hushe Valley, the average carrying capacity was found as 19 hectare/Animal. Unit/5 months. In Thallay Valley, the average carrying capacity was found as 16 hectare/Animal.Unit/5 xxiv months. This extremely low productivity and carrying capacity of range shows the critical condition of range sites in the valleys due to heavy grazing by livestock and climatic factors, specifically rain fall and soil characteristics such as organic matter and soil phosphorus. A livestock survey was conducted to check the grazing pressure with a semi structured questionnaire and the type of livestock was noted in each village. For assessment of Capra ibex in Hushe, two permanent trails - one upstream (7 km) from Hushe village to Dumsum Junction and one downstream (5 km) from Hushe village to Hushe Bridge - were established along the Hushe River. In Hushe Valley, the average livestock holdings per household were 17.14 animals. In Thallay Valley, the average livestock holding size was 15.25 animals per household. The number of dzomo per household has decreased because of the changing trend from agriculture to employment. The dzomo needs to be grazed on the pasture because of their grazing behavior which people can’t afford due to their jobs. The grazing period was dependent upon climatic condition and the harsh winter was a factor to control livestock numbers in both valleys. The population density of Himalayan Ibex was 3.44 animal / km2 during winters in the Hushe Valley. In winter, ibex come down to the surroundings of the main Hushe Nallah (3000-3600 m) for grazing, due to a shortage of grasses at higher altitude because of snow cover. The number of ibex seems to be increasing due to non-interferences of human beings. The average number of trophy size ibex was 3.54 in each of studied locations. This study revealed that the number of hunting licenses may need to be increased for the sustainable conservation of ibex and co-existence of both livestock and ibex, and to reduce the pressure on rangeland grasses. xxv For the assessment of competition, a total of 150 faecal pellets were collected. Each of 50 samples for Himalayan Ibex (hereafter referred to as ibex), domestic goat and domestic sheep (hereafter referred to as goat and sheep) were collected from Hushe Valley during the winter season from November 2012 to February 2013. The images of faecal fragments were compared with the plant reference photomicrographs. Frequency occurrence, relative importance value (RIV) and diet selection value (DSV) were calculated to estimate the diet overlap between the wild ungulates and domestic ungulates and thus to measure their overall diet similarity. The present study revealed that the shrub Rosa webbiana is the most preferred plant species in winter for ibex, goat and sheep with the highest diet selection values. The Salix illensis is also an important source of food for sheep and goat. The Artemisia bravifolia shows considerable contribution to the diet of ibex. The diet overlap index between ibex and goat was calculated as 0.86. The diet overlap index between ibex and sheep was 0.85, whereas the diet overlap index between sheep and goat was 0.96. The value of ( ) is closer to each other and closer to 1.00, which showed potential of competition among all species in winter season. This high diet overlap in winter was due to the downward movement of ibex in winter to search for food. The livestock also graze during day time in the surrounding areas therefore there is a possibility of high competition for the available forage in winter season. The results of the present study revealed that there is a high amount of pressure on the lower rangeland resources in winter seasons, as livestock graze in the lower ranges more frequently
