Examining the dimensions of corporate entrepreneurship construct: A validation study in the Pakistani banking context
Corporate Entrepreneurship is globally advancing phenomena.Organizations in the search of excellence, increase in their financial and non-financial gains are adopting corporate entrepreneurship for a better tomorrow. Prominent scholars played a significant role in the development, understanding and advancement of corporate entrepreneurship.In this respect, particularly for measuring the state of corporate entrepreneurial activities inside a firm, the researchers developed tools to measure and assess it.In pursuing that objective the Corporate Entrepreneurship Assessment Instrument (CEAI) was developed.As this instrument was mainly developed and tested in the United States and Canada therefore, in this study the psychometric
properties of Corporate Entrepreneurship Assessment Instrument construct are assessed in the Pakistanās context.Two hundred and sixty five bank branch managers from big five banks of Pakistan were surveyed.We analysed the data using
Smart PLS 3.0 software due to its methodological usefulness. The findings demonstrated that the scale has adequate level of internal consistency reliability, convergent validity and discriminant validity for each CEAI dimension. Based on above findings, it is suggested that CEAI construct can be effective in measuring the corporate entrepreneurship in the banking sector of
Pakistan.Therefore, the potential researchers are suggested to employ this tool in measuring corporate entrepreneurship in the developing countries and in Pakistan specially
Clinical Decision Support System for Unani Medicine Practitioners
Like other fields of Traditional Medicines, Unani Medicines have been found
as an effective medical practice for ages. It is still widely used in the
subcontinent, particularly in Pakistan and India. However, Unani Medicines
Practitioners are lacking modern IT applications in their everyday clinical
practices. An Online Clinical Decision Support System may address this
challenge to assist apprentice Unani Medicines practitioners in their
diagnostic processes. The proposed system provides a web-based interface to
enter the patient's symptoms, which are then automatically analyzed by our
system to generate a list of probable diseases. The system allows practitioners
to choose the most likely disease and inform patients about the associated
treatment options remotely. The system consists of three modules: an Online
Clinical Decision Support System, an Artificial Intelligence Inference Engine,
and a comprehensive Unani Medicines Database. The system employs advanced AI
techniques such as Decision Trees, Deep Learning, and Natural Language
Processing. For system development, the project team used a technology stack
that includes React, FastAPI, and MySQL. Data and functionality of the
application is exposed using APIs for integration and extension with similar
domain applications. The novelty of the project is that it addresses the
challenge of diagnosing diseases accurately and efficiently in the context of
Unani Medicines principles. By leveraging the power of technology, the proposed
Clinical Decision Support System has the potential to ease access to healthcare
services and information, reduce cost, boost practitioner and patient
satisfaction, improve speed and accuracy of the diagnostic process, and provide
effective treatments remotely. The application will be useful for Unani
Medicines Practitioners, Patients, Government Drug Regulators, Software
Developers, and Medical Researchers.Comment: 59 pages, 11 figures, Computer Science Bachelor's Thesis on use of

Assessment of antimicrobial, antialgal and cytotoxic activities of crude extracts from rhizospheric and freshwater cyanobacterial strains
Background:Ā This study describes the evaluation of antimicrobial, antialgal and cytotoxic activities of crude extracts from cyanobacterial strains isolated from rhizospheric and freshwater environment.Methods:Ā Four cyanobacterial strains were isolated from freshwater and rhizospheric samples collected from various sites of University of the Punjab, Lahore, Pakistan. Selected strains were identified by 16S rDNA ribotyping as species of genera, Cyanothece (CY1), Synechococcus (CY2), Leptolyngbya (CY3) and Synechococcus (CY4). The organic extracts i.e., methanolic, ethanolic and acetonic of selected cyanobacterial strains were checked for antibacterial and cytotoxic activity. Antibacterial and antialgal activities of cyanobacterial extracts were determined against, four Gram positive and three Gram negative bacteria using Muller-Hinton (MH) agar well diffusion assay and two algal species using 96-well microtiter plate respectively. Cytotoxic activity was determined against Vero cells and Huh-7 cells.Results:Ā The results showed that all cyanobacterial extracts showed activities against Gram positive bacteria while some of the extracts showed activity against Gram negative bacteria. Acetonic extract of CY4 and CY2 showed moderate discoloration againstĀ ChlamydomonasĀ sp. andĀ ChroococcusĀ sp. respectively. In cytotoxicity bioassay, methanolic extracts of strain CY1 and CY2 were most active with an IC50 of 0.625 mg/ml against Vero cells while acetonic extract of strain CY1 showed highest activity against Huh-7 cells (p<0.05).Conclusion:Ā The data of current study conclusively suggest that selected cyanobacteria may be an excellent source for further fractionation to obtain novel antibacterial, antialgal and anticancer substances.Keywords:Ā Cyanobacteria; MTT bioassay; Microtiter plates; Antimicrobial activity; Cytotoxicity
Social and Macroeconomic Uncertainty and Private Savings: A Case Study of a Developing Economy
We examine the effects of various new variables relating to uncertainty and find that āsocial uncertaintyā in the form of increased crime is leading to portfolio substitution from bank accounts towards savings in durable goods and other real assets in a typical low middle income economy of Pakistan. Accounting for the cultural phenomena of savings in gold and non-bank real assets in South Asia, we have modeled macroeconomic uncertainty through both the levels and the volatilities of gold prices and the stock market index, as well as income volatility. We find that higher social and macroeconomic uncertainty leads to larger precautionary savings in non-bank assets and thereby results in lower residual savings in the National Income Accounts; this result is robust and invariant to various measures of uncertainty. We also find support for the Permanent Income Life Cycle hypothesis and āweak formā evidence for Ricardian equivalence.
Keywords: Private savings, Uncertainty, Consumer Durables

Impact of Macro Specific Factor and Bank Specific Factor on Bank Liquidity using FMOLS Approach
By applying the fully modified ordinary least square (FMOLS), this study examines the impact of bank-specific factor and macro-specific factors on bank liquidity, for the period of 2000 to 2017. The bank specific factors include bank crises, bank size, total deposit, and profitability. While it considers a macro-specific factors GDP, inflation, monetary policy and unemployment. Findings reveal that based on time series data, we suggest that bank-specific and macro-specific factor significantly effect on bank liquidity. Empirical results reported that at 5 percent level of significance total deposit, GDP, bank size and unemployment have a negative impact on liquidity of the bank. While monetary policy, bank crisis and profitability have a positive impact on liquidity. Inflation has an insignificant relation with liquidity. The study reported new facts for increase more clear understanding of liquidity in a developing country like Pakistan
Investigation of Toxic Metals in the Tobacco of Pakistani Cigarettes Using Proton-Induced X-Ray Emission
A particle-induced X-ray emission (PIXE) study has been carried out to find out whether available local and imported cigarette brands in Pakistan have elevated concentration of metals or not. The results are compared within the brands examined in this study and with the results of related studies in literature. A sum of 19 different cigarette brands was purchased randomly from different Pakistani markets which included local and imported brands. The concentration of elements like Cd, Pb, Zn, Fe, Mn, Ni, Cu, and Co was investigated. Results showed that different cigarette brands have different metal contents. The mean concentration of the heavy metals is Cdā4.92Ā Ī¼g/g, Coā0.12Ā Ī¼g/g, Cuā0.97Ā Ī¼g/g, Niā0.13Ā Ī¼g/g, Pbā1.02Ā Ī¼g/g, and Znā12.91Ā Ī¼g/g per dry weight. Compared with the reported results of other international studies, Pakistani cigarettes are observed to have lower heavy metal contents except for cadmium which was higher. This study will provide adequate data for all concerned departments. This study will also create awareness among people about the toxicity of metals present in tobacco of cigarettes
