Data mining is a procedure of extracting the requisite information from unprocessed records by using certain methodologies and techniques. Data having sentiments of customers is of utmost importance for managers and decision-makers who intend to monitor the progress, to maintain the quality of their products or services and to observe the latest market trends for business support. Billions of customers are using micro-blogging websites and social media for sharing their opinions about different topics on daily basis. Therefore, it has become a source of acquiring information but to identify a particular feature of a product is still an issue as the information retrieves from varied sources. We proposed a framework for data acquisition, preprocessing, feature extraction and used three supervised machine-learning algorithms for classification of customers' sentiments. The proposed framework also tested to evaluate the system's performance. Our proposed methodology will be helpful for researchers, service providers, and decisionmakers.

One part of this paper uncovers how the politics around the demands for the dissolution and re-election of the Constituent Assembly of Pakistan took place subsequent to the elections for the country's provincial legislatures, especially in East Pakistan. Following the dissolution of the Assembly, Pakistan was tangled into a political quagmire about the election of the successor of the Constituent Assembly. The politics around pre-election legislation to resolve this predicament is recorded in the second part of the study. The British archival record makes the most of source material of this study. These records provide impartial and third party accounts – hence are reliable sources – of the political developments of the period under consideration. As in the period, Pakistan was a dominion state under the British the records of Dominion Office (DO) or Commonwealth Relations Office (CRO) bear detailed inside and secret information that is rarely available in indigenous historical works. Therefore, the study provides a thorough and impartial historical explanation of the electoral politics on the dissolution of the original Constituent Assembly and formation legal framework for the constitution of the new Assembly.

Almost every state or society particularly a pluralistic one is composed of various nationalities or sub-national groups whereas every segment has its own distinct identity being a source of pride and strength for its survival. In relatively homogenous societies, the process of nation-building though not easy is at least less cumbersome whereas in pluralistic societies this process demands a lot of hard work on the part of the elite who must exhibit vision, wisdom, foresight and patience; because such societies are always fraught with the danger that any of the nationalities or sub-national group may dominate the others. The societies having a considerable level of social, cultural and linguistic heterogeneity hence horizontally/vertically divided and cross-divided in the pursuit of their distinct preferences and priorities can hardly be united under a single administrative structure nevertheless they can be persuaded to form a union under some common government. For this purpose, a federal arrangement may be suitable option because it provides for unity in diversity rather than unity in its absolute terms. The federation of Pakistan, since its vey inception, is struggling to create the said unity particularly with reference to the situation in Balochistan which is facing a long and multi-faceted unrest posing a substantial challenge for the federation. The present study empirically explores the nature of grievances of the people of Balochistan with respect to the federation of Pakistan by conducting a field survey and establishes that majority of the people of Balochistan do not believe that the federal design in Pakistan is functioning in its true letter and spirit with reference to Balochistan.

Purpose This study investigates the impact of geopolitical risk (GPR) on foreign remittances (FRs) for the top remittance-receiving countries.Design/methodology/approach The sample includes Mexico, France, Egypt, China, the Philippines, India, Vietnam, Ukraine, Germany and Belgium for the annual period of 1998–2022 using the nonlinear panel autoregressive distributed lag (ARDL) model to determine the asymmetry in the relationship.Findings The results suggest that, in the short term, positive GPR shocks have a positive and significant impact on FRs received. On the other hand, the long-run results suggest that adverse GPR shocks negatively affect FRs received in the sampled countries. Additionally, the study confirms the asymmetric impact of GPR on top remittances received in countries.Research limitations/implications The policymakers, migrants and recipients should consider the asymmetric nature of GPR while making decisions regarding policies and the transfer of remittances. This information can be used to create more effective policies for controlling and reducing the effects of GPR on overseas remittances, such as assisting migrant workers and developing methods to lessen the volatility of these flows.Originality/value Acknowledging the potential fluctuations and uncertainties associated with GPR is crucial to make informed choices regarding remittance-related matters.

The paper provides an updated evidence of the linkage between stock market and macroeconomic factors in Pakistan. The sample period is from January 2011 to November 2017. Macroeconomic variables used are money supply, exchange rate, treasury bill rate, inflation and industrial production. Generalized autoregressive conditional heteroscedasticity (GARCH) models have been used to examine the impact of macroeconomic factors on stock market return and stock market volatility. Findings suggest that macroeconomic factors have an impact on stock market volatility. The fluctuations in inflation and money supply negatively influence the volatility of stock market returns. In contrast, industrial production positively affects the fluctuations of stock market returns. The findings are important for shareholders, investors, regulatory authorities and policymakers.

Purpose
This paper aims to investigate the impact of economic, social and political globalizations on the incidents of global terrorism.


Design/methodology/approach
The authors apply negative binomial regressions model because the variable is event count. The sample size covers 195 countries from 1990 to 2017.


Findings
There is strong evidence that the higher level of economic and social integrations internationally lead to a reduction in terrorist activities. However, the results relating to political globalization are inconsistent. Comparing the top 20 most affected countries with the full sample, the authors find a negative association between economic globalization and terrorism, whereas social and political globalization is found to be statistically insignificant. Finally, the evidence holds firmly pre-9/11 attacks on World Trade Centre.


Research limitations/implications
This paper suffers through the lack of consensus on a unique and consistent definition of terrorism. The definition of terrorism varies across time and countries. Furthermore, there is a variation among the main databases of terrorism, which could potentially affect the reliability of findings.


Practical implications
This paper provides policymakers with a policy recommendation that the economic and social integration across countries should be encouraged, as it might decrease the number of terrorist events taking place worldwide. In addition, the benefits of economic development generated through global integration must be fairly distributed across societies as an effort to decrease motivation of disgruntles population to involve in terrorism.


Originality/value
This paper contributes empirically to the existing literature through investigating the impact of economic, social and political globalizations on the incidents of terrorism worldwide.
