The paper provides an overview of the evolution of Social Sciences with a focus on the Post-1945 period, known for major strides towards scientific, analytical, nonpartisan, multi-disciplinary and comprehensive study and research in different fields of Social Sciences. The paper discusses the gradual growth of Social Sciences in Pakistan in terms of increase in number of persons engaged in teaching, research and practice in various domains of Social Sciences, institutional facilities and availability of funds. There is a discussion of the major features of the research work done in Social Sciences in Pakistan and its weaknesses and deficiencies. The paper argues that Social Sciences have become important for societies like Pakistan that face different types of social and political conflicts. The rise of religious extremism, violence and terrorism also requires that we benefit from the work done in different fields of Social Sciences for understanding the dynamics of societal trends, issues and conflict and how to address them. The paper also reviews teaching and research being done in Pakistani universities, especially since 2005, when more funds became available for study and research in Social Sciences. The universities have vastly expanded their Doctoral and M.Phil. porgrammes but the imperative of quality is often neglected.

Chatbot has emerged as a significant resolution to the swiftly growing customer caredemands in recent times. Chatbot has emerged as one of the biggest technological disruption. Simply speaking, it is a software agent facilitating interaction between computers and humans in natural language. So basically, it is a simulated, intellectual dialogue agent functional in a range of consumer engagement circumstances. It is the easiest and simplest means enable interaction between the retailers and the customers. </p><p> • Purpose- Most of the research work done in this field is concerned with their technical aspects. The recent research on chatbot pay little attention to the impact it is creating on users’ experience. Through this work, author is making an effort to know the customer-oriented impact that the chatbot bear on the shoppers. The purpose of this study is to develop and empirically test a framework that identify the customer oriented attributes of chatbot and impact of these attributes on customers. </p><p> • Objectives- The study intends to bridge the gap between concepts and actual attributes and applications on the subject of Chatbot. The following research objectives can address the various aspects of Chatbot affecting the different characteristics of consumers shopping behaviors: a) Identify the various attributes of chatbot that bears an impression on consumer shopping behavior. b) Evaluate the impact of chatbot on consumer shopping behavior that leads to the development of chatbot usage and adoption among the customer. </p><p> • Design/Methodology/Approach – For the purpose of analysis, author has administered Factor analysis and Multiple regression using SPSS version 23 for identification of various attributes of Chatbot and knowing their impact on shoppers. A self-administered questionnaire from the review of literature is developed. Industry experts in the field of retailing and academician evaluate the questionnaire. Primary information from the respondents is gathered using this questionnaire.

The Impact

Increasingly, raw materials of natural origin are used as fillers in polymer composites. Such biocomposites have satisfactory properties. To ensure above-average functional properties, modifications of biofillers with other materials are also used. The presented research work aimed to produce and characterize elastomeric materials with a straw-based filler and four different types of montmorillonite. The main research goal was to obtain improved functional parameters of vulcanizates based on natural rubber. A series of composites filled with straw and certain types of modified and unmodified nano-clays in various ratios and amounts were prepared. Then, they were subjected to a series of tests to assess the impact of the hybrids used on the final product. It has been shown that the addition of optimal amounts of biofillers can, inter alia, increase the tensile strength of the composite, improve damping properties, extend the burning time of the material and affect the course of vulcanization or cross-linking density.

Early detection of breast abnormalities remains the primary prevention against breast cancer despite the advances in breast cancer diagnosis and treatment. Presence of mass in breast tissues is highly indicative of breast cancer. The research work presented in this paper investigates the significance of different types of features using proposed neural network based classification technique to classify mass type of breast abnormalities in digital mammograms into malignant and benign. 14 gray level based features, four BI-RADS features, patient age feature and subtlety value feature have been explored using the proposed research methodology to attain maximum classification on test dataset. The proposed research technique attained a 91% testing classification rate with a 100% training classification rate on digital mammograms taken from the DDSM benchmark database.

The addition of a photocatalyst to ordinary building materials such as concrete creates environmentally friendly materials by which air pollution or pollution of the surface can be diminished. The use of LiNbO3photocatalyst in concrete material would be more beneficial since it can produce artificial photosynthesis in concrete. In these research photoassisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using a photocatalyst, LiNbO3, coated on concrete surface under illumination of UV-visible or sunlight and showed that LiNbO3achieved high conversion of CO2into products despite the low levels of band-gap light available. The high reaction efficiency of LiNbO3is explained by its strong remnant polarization (70 µC/cm2), allowing a longer lifetime of photoinduced carriers as well as an alternative reaction pathway. Due to the ease of usage and good photocatalytic efficiency, the research work done showed its potential application in pollution prevention.

Comprehensive Study

This article is devoted to a comprehensive study of the structural and semantic features of dish names and their descriptions in German in the field of restaurant discourse. The study employs cognitive discourse analysis, elements of comparative and contextological approaches, taking into account linguocultural parameters. The relevance of the comprehensive study of the names of dishes in restaurant discourse is due to an increased interest in the parameterization of lexical units in different types of institutional discourse. The scientific novelty of this work lies in the fact that for the first time, within the framework of a restaurant menu, not only the nomination of a dish is considered, but also the structural and semantic characteristics of its description are analysed. An attempt is made to analyse a connection between the nominations of dishes and their description in the restaurant menu, as well as to determine the semantic dominants of the genre under study. It is concluded that the text of the menu as a whole presents a combination of the language for special purposes and the language of advertising. In interaction with extralinguistic factors, the nominations of dishes and their descriptions not only document the culture of food in society, but also reflect the ethnocultural picture of the world. Based on the analysis of the menu texts, it is established that structurally the names of dishes are complex words or phrases, built mainly according to the attributive model. The description of dishes performs the function of verbalizing the sensations of taste and clarifying the method of preparing dishes, characterizing the quality of dishes, their ingredients, and the intensity of taste. Evaluative parameters in descriptions are expressed at the lexical, grammatical, syntactic and stylistic levels.

Fault Lines

Leaving academia, this essay joins a steady chorus of reflection now thinking backwards over the last half century of extraordinary transformations in higher education. The industry is booming, more students than ever are entering universities, yet the academy is seen as increasingly in crisis. Staff workloads keep mounting, student debt soaring, and staff and student anxieties alike are multiplying, even as government underfunding, imposed managerialism and commercialisation threaten to reduce the underlying logic of higher education to market principles. In this context it is more urgent than ever to record the half century of struggle that opened up and enriched academic life, gradually ensuring the entry of hitherto excluded voices and topics into research and scholarship, especially in the humanities and social sciences. Drawing on my own involvement, I recall some of these always-incomplete attempts to challenge the fault-lines of intellectual life in the academy, knowing that we need always to cherish the value of teaching, research and learning, simply for its own sake.

The Relationship

Abstract Based on strategic human capital theory, this study examines the effects of star surgeons on two different types of healthcare outcomes (i.e., number of surgical patients and length of patients’ in-hospital stay after surgery) in the surgery department. We also explore whether the relationship between star surgeons and healthcare outcomes is contingent on the expertise disparity between star and non-star surgeons. The results of an empirical analysis on colorectal cancer surgeons in 80 departments in South Korean hospitals show that the number of star surgeons increases the number of surgical patients and reduces the length of patients' stay after surgery. Moreover, the positive relationship between star surgeons and the number of surgical patients is strengthened when the expertise disparity between star and non-star surgeons is low. The implications of these findings for research and practice are also discussed.
