Historical Analysis of Bank Profitability Using CAMEL Parameters: Role of Ownership and Political Regimes in Pakistan

In first sixty years of its existence financial sector of Pakistan has experienced two prominent episodes. One, there was an experimentation with the ownership structure of financial institutions which started with promotion of ownership by the private sector and then in 1970s they were nationalized. Subsequently the process was reversed in the 1990s transferring most of the banking assets back to the private sector. Two, on the political front, for long 33 years autocrat have interrupted the democratic order many times. The objective of this study is to take stock of the performance of banking industry when it was in private hands vis-à-vis when banks were nationalized, and, as a supplement, to evaluate the impact of dictatorship versus democracy on the performance of banking industry. Using historical dataset this study offers analysis of banking sector performance by using CAMEL parameters. Our main findings are that when banks are in private hands their profitability is positively related to quality of their assets and management, and it has negative relation with capital adequacy and liquidity. However when banks are under government ownership asset quality and liquidity become irrelevant in determining the profitability whereas capital adequacy, management quality continue to impact bank profitability. This implies that government ownership works like implicit guarantee for banks (a) that they would remain solvent in the short run], and (b) that it would absorb losses emanating from deterioration of bad assets.

Re-examining obesity prevention strategy: is social marketing still a relevant option?

Globally, obesity is among the five leading risk factors for death. While the increase in obesity is a worldwide phenomenon, the rate of increase in England is of particular concern for local health authorities and policy makers. At the current rate, the prevalence is estimated to increase from 26% in 2010 to over 50% by 2050. This underscores the need for an urgent review of current strategy to inform policy makers and programme managers. Social marketing is a recognised intervention method for systematically influencing behaviour and has been used effectively in various health programmes worldwide, including the United Kingdom, for obesity control. This paper examines the underlying assumptions and implications of a social marketing framework and critically assesses the impact of various interventions to reduce obesity, including the social marketing campaigns by the Department of Health (DH), UK. The paper concludes that the social marketing framework, designed with end users in mind, has robust explanatory powers in relation to the adoption of a healthy lifestyle. However, interventions using a social marketing framework have produced limited results. The less-than-optimum performance may be attributed to various factors, including poor understanding and/or application of behavioural theories, lack of customer insight, and absence of meaningful exchange opportunities. Further research is needed in order to understand behaviour, specific to diet and physical activity, and the significance of legislation on marketing of food products

Synthesis, Characterization, and Investigation of Novel Ionic Liquid-Based Tooth Bleaching Gels: A Step towards Safer and Cost-Effective Cosmetic Dentistry

The objective of this study was to synthesize a novel choline hydroxide ionic liquid-based tooth bleaching gel. Ionic liquid-based gels were synthesized and characterized using FTIR along with pH testing. Tooth sample preparation was carried out in line with ISO 28399:2020. The effects of synthesized gels on tooth samples were tested. Tooth samples were stained and grouped into three experimental groups: EAI (22% choline hydroxide gel), EAII (44% choline hydroxide gel), and EB (choline citrate gel) and two control groups: CA (commercial at-home 16% carbamide peroxide gel) and CB (deionized water). The tooth color analysis, which included shade matching with the Vitapan shade guide (n = 2), and digital colorimetric analysis (n = 2) were evaluated. The surface characteristics and hardness were analyzed with 3D optical profilometry, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), and Microhardness testing (n = 3), respectively. The tooth color analysis (Vitapan shade guide) revealed that all the tooth samples treated with synthesized choline citrate gel (EB) showed an A1 shade as compared to the other four groups, giving a range of shades. An analysis of the ΔE values from digital colorimetry; EAI, EAII, CA, and CB showed ΔE values in a range that was clinically perceptible at a glance. However, EB showed the highest value of ΔE. The mean microhardness values for the five groups showed that the effects of three experimental gels i.e., 44% choline hydroxide, 22% choline hydroxide, and choline citrate, on the microhardness of the tooth samples were similar to that of the positive control, which comprised commercial at-home 16% carbamide peroxide gel. SEM with EDX of three tested subgroups was closely related in surface profile, elemental composition, and Ca/P ratio. The roughness average values from optical profilometry of four tested subgroups lie within approximately a similar range, showing a statistically insignificant difference (p > 0.05) between the tested subgroups. The synthesized novel experimental tooth bleaching gels displayed similar tooth bleaching actions without any deleterious effects on the surface characteristics and microhardness of the treated tooth samples when compared with the commercial at-home tooth bleaching gel
