This study examines whether a firm’s management earnings forecasts affect its technical innovation activities. Our study also examines whether the cost of debt plays a mediating role between the management earnings forecasts and the innovation nexus.

We obtained data from 1,032 Chinese non-financial firms listed on the Shanghai and Shenzhen stock markets from 2005 to 2022 (i.e. 18,576 firm-year observations). We used various econometrics techniques, such as Heckman’s (1979) two-stage selection method and two-stage least square, to examine the relationship between management earnings forecasts and the firm’s technical innovation activities.

We find a positive relationship between management earnings forecasts and the firms' technical innovation. We also find that the cost of debt mediates the relationship between management earnings forecast and technical innovation. Further analysis indicates that frequent earnings forecasts provide incremental information regarding a firm’s future value and cash flows, thus reducing the volatility and uncertainty in cash flow calculations. Our findings are robust to several tests.

Our study has implications for policymakers, practitioners and high-level management of Chinese firms, enabling them to understand the relationship between management earnings forecasts and firms' innovation activities.

The purpose of this study is to analyze the dynamic causal relationship between foreign direct investment (FDI), gross domestic product (GDP) and trade openness (TO) on a set of five selected South Asian countries.

This study used newly developed bootstrap auto regressive distributed lags (ARDL) cointegration test to examine the long-run relationship among FDI, GDP and TO for selected South Asian countries for 1975–2016.

The economic growth (EG) is significantly related to TO for Bangladesh, India and Sri Lanka and the expansion of TO is crucial for growth in these countries. The results show that all countries (except Bangladesh) found the existence of long-run cointegration between FDI, GDP and TO, whereas FDI is a dependent variable. These results concluded that FDI and TO are contributing to EG in these selected countries.

This study is one of the first attempts to investigate the causal relationship and address the short and long dynamic among FDI, GDP and TO regarding five south Asian countries such as Bangladesh, India, Nepal, Pakistan and Sri Lanka.

Depleting reserves of crude oils and their adverse environmental effects have shifted focus toward environment friendly and biobased lubricant base oils. Natural oils and fats act as good lubricants but they have low oxidation and thermal stability which makes them unsuitable for modern day uses. This paper aims to produce trimethylolpropane ester biolubricant from cottonseed oil and study the effects of its use in spark ignition (SI) engines.

In this work, cottonseed oil is converted to TMP lubricant by a two-step based catalyzed esterification. The lubricants thermophysical properties are then analyzed and a 20% blend with synthetic poly-alpha olefin is used in an spark ignition engine.

The produced lubricant has viscosity @100^oC of 4.91 cSt, a viscosity index of 230 and a flash point of 202^oC. When used as a 20% blend in a petrol engine, the rate of oil deterioration was reduced by 18%, however, the overall wear increased by 6.7%. However, this increase is offset by its improved environmental impacts.

In its current state, such a biolubricant can be used as an additive to most commercially available lubricants to improve oil deterioration characteristics and environmental impact. However, further work on improving biolubricant’s wear characteristics is needed for the complete replacement of mineral oil-based lubricants.

This paper aims to focus on technical and economical analysis of small scale wind/solar hybrid system for domestic consumers. The analysis is carried out on HOMER II simulation software. Pakistan is one of those developing countries which are encountered with severe energy crises. The purpose of this paper is to introduce a technically and economically feasible system to meet the domestic consumer’s demand, as well as contribute to the central grid. HOMER Energy software is used to analyze different systems and to obtain the most reliable and feasible system for the customer. Simulation was carried out to find an economically and technically feasible system. Sensitivity analysis was carried out with hub height, PV De-rating factor, PV life, Wind turbine life. Change in hub height drastically affected energy production and economic prospect as the main factors of the system. Implementing such type of small hybrid systems on domestic level can be truly helpful to overcome energy shortage.

The purpose of this paper is to highlight the studies of momentum and transmission of heat on mixed convection boundary layer Darcy‒Forchheimer flow of Casson liquid over a linear extending surface in a porous medium. The belongings of homogeneous‒heterogeneous retorts are also affianced. The mechanism of heat transmission is braced out in the form of Cattaneo‒Christov heat flux. Appropriate restorations are smeared to revolutionize coupled nonlinear partial differential equations conforming to momentum, energy and concentration of homogeneous‒heterogeneous reaction equations into coupled nonlinear ordinary differential equations (ODEs).

Numerical elucidations of the transmogrified ODEs are accomplished via a dexterous and trustworthy scheme, namely optimal homotopy analysis method. The convergence of planned scheme is exposed with the support of error table.

The exploration of mixed convection Darcy‒Forchheimer MHD boundary layer flow of incompressible Casson fluid by the linear stretched surface with Cattaneo‒Christov heat flux model and homogeneous‒heterogeneous reactions is checked in this research. Imitations of the core subsidized flow parameters on velocity, temperature and concentration of homogeneous‒heterogeneous reactions solutions are conscripted. From the recent deliberation, remarkable annotations are as follows: non-dimensional velocities in x_a− and x_b− directions shrink, whereas the non-dimensional temperature upsurges when the Casson fluid parameter ameliorates. Similar impact of Casson fluid parameter, magnetic parameter, mixed convection parameter, inertia parameter, and porosity parameter is observed for both the components of velocity field. An escalation in magnetic parameter shows the opposite attitude of temperature field as compared with velocity profile. Similar bearing of Casson fluid parameter is observed for both temperature and velocity fields. Enhancement in concentration rate is observed for growing values of (N_s) and (Sc), and it reduces for (k₁). Both temperature and concentration of homogeneous‒heterogeneous upturn by mounting the magnetic parameter. Demeanor of magnetic parameter, Casson fluid parameter, heat generation parameter is opposite to that of Prandtl number and thermal relaxation parameter on temperature profile.

In many industrial and engineering applications, the current exploration is utilized for the transport of heat and mass in any system.

As far as novelty of this work is concerned this is an innovative study and such analysis has not been considered so far.

The learning outcomes are as follows: what tasks are to be done by medical representatives in pharmaceutical industry? This study also highlights various competencies required to do effective selling in this industry; analyzes and discusses different unethical practices going on in the market; explains why ethical norms are necessary in sales context when sales targets are already achievable with unethical means; and develops and comments on strategies Flori Pharmaceutical can make to overcome on these unethical issues. What should be the response of Dahar to the email of Naveed khan? What course of action should be taken by Dahar in the deceitful reporting case of Mohsin Ali?

Flori is considered a leading and growing multinational organization in the highly competitive environment of Pakistan pharmaceutical industry with over 40 years of experience. The company aims to command a leading position in developing new health-care products as it offers a wide range of diabetic, cardiovascular, respiratory and vitamin products based on quality as a result of high research and examination. Recently, an email to Bilal Dahar on March 2017 from Flori’s star sales person Naveed Khan has forced management to take some strong decisions regarding ethical norms and values to be adopted by medical representatives of Flori pharmaceuticals. The email highlighted the issues related to sales pressure which are leading toward unethical sales practices. Dahar just not have to maintain Flori’s ethical code of conduct but he and his team also has to work hard to achieve more than 26% growth rate in sales revenue as compared to last year. Dahar knew that the highly competitive environment of pharmaceutical industry has led most of the stake holders to indulge in unethical behavior to achieve their individual targets. He knew that this is dangerous in long term for the multinational organizations such as Flori pharmaceuticals as if the similar behavior continues, the sales culture and values of the organization would be on stake. He also has to decide what decision to be taken against deceitful reporting issue of one of the top-performer territory managers, who was key person in helping Flori to close the sales year 2016 with the revenue of Rs. 6.4bn, a 26% growth over the last year. The case is rich enough to provide a platform regarding management of several ethical challenges in pharmaceutical selling and developing strategies based on them.

Despite the growing interest in closed-loop manufacturing, there is a lack of comprehensive frameworks that integrate product development, production processes, people and policies (4Ps) to optimize sustainable manufacturing performance. This study investigates the influence of the four Ps of closed-loop manufacturing systems (product development, production processes, people and policies) on sustainable manufacturing performance (SMP).

To investigate the influence of the four Ps on SMP, a hybrid analytical model was employed, combining structural equation modeling (SEM) with artificial neural networks (ANN). Data were collected through a structured survey administered to 353 manufacturing firms in Malaysia. SEM was used to assess the relationships between the variables, while ANN was employed to capture nonlinear relationships and improve prediction accuracy.

The research findings demonstrate that product development practices, including eco-design, life cycle assessment and resource planning, exert the most significant influence on SMP. Furthermore, implementing green and lean manufacturing techniques, energy modeling and material utilization/toxicity planning significantly enhances sustainability outcomes. While the social setting (employee motivation, turnover and work–life quality) does not directly impact SMP, it plays a pivotal role in facilitating the implementation of internal environmental policies. Moreover, environmental management practices, both mandatory and voluntary, serve as intermediaries between the four Ps and SMP within closed-loop manufacturing systems.

The findings offer valuable insights for policymakers, industry leaders and manufacturing organizations. By prioritizing product development, implementing green and lean manufacturing practices and fostering a positive social setting, organizations can significantly enhance their sustainable performance. Additionally, the study highlights the importance of effective environmental management practices in mediating the relationship between other factors and SMP.

This study contributes to the literature by providing a comprehensive framework for understanding the factors that drive sustainable manufacturing performance. The hybrid SEM-ANN model offers a robust and innovative approach to analyzing the complex relationships between the four Ps and SMP.

Present work deals with the partial substitution of cement by waste demolished concrete powder (WDP) for reducing the carbon footprints of concrete.

Control specimens and the specimens with 20% WDP as fractional substitute of cement were prepared. The waste powder was thermally activated at 825 °C prior to its use in the mix. The prepared specimens were evaluated in terms of density, workability, mechanical strength, Ultrasonic pulse velocity (UPV) and rebound hammer (RH).

The results showed that with the substitution, the workability of the mix increased, while the density decreased. A decrement within a 20% limit was found in compressive strength. The UPV and RH results were closely linked to the other results as mentioned above.

The study deals with only M15 concrete and the substitution level of only 20% as a baseline.

The concrete containing 20% WDP is lightweight and more workable. Moreover, its strength at 28 days is 14 MPa, only 1 MPa lesser than the characteristic strength.

The WDP can be recycled and the dumping in landfills can be reduced. This is an important effort towards the decarbonation of concrete.

Previous literature indicates that the WDP has been frequently used as a partial replacement of aggregates. However, some traces of secondary hydration were also reported. This work considers the effect of partial substitution of cement by the WDP.

This study aims to examine whether corporate social responsibility (CSR) of Islamic banking is delivering financial returns or otherwise enhancing the cost.

The methodology of this study includes the content-analysis approach with aid of the CSR disclosure index, and it deploys the partial least squares regression to examine the CSR-financial performance relationship. Regarding CSR disclosure and financial measures, this study takes the data from the annual reports of Islamic banking of Pakistan, from the year 2003 to 2017.

The results of this study indicate that there is a significant positive relationship exists between CSR and financial performance of Islamic banks, consistent with the instrumental-stakeholder theory. These results imply that Islamic banks, which ensure that CSR is practiced extensively, and aim to positively affect their stakeholders, perform well. Hence, the CSR engagement by Islamic banks yields instrumental returns rather it is a cost.

Islamic banks of Pakistan must work on a better CSR policy, it would enhance the reputation of Islamic banks, on the other hand, it would also increase their capabilities to cope with future reputation damage and negative news, thus it would protect and secure the financial results. In addition to these, investors of Islamic banks must also look at the social and ethical engagements of Islamic banks of Pakistan, while making investment decisions.

In general, there is a dearth of research in the domain of CSR-financial performance regarding Islamic banking. This is one of the studies which contributes to this area.
