Code Sharing in Healthcare Research: A Practical Guide and Recommendations for Good Practice

As computational analysis becomes increasingly more complex in health research, transparent sharing of analytical code is vital for reproducibility and trust. This practical guide, aligned to open science practices, outlines actionable recommendations for code sharing in healthcare research. Emphasising the FAIR (Findable, Accessible, Interoperable, Reusable) principles, the authors address common barriers and provide clear guidance to help make code more robust, reusable, and scrutinised as part of the scientific record. This supports better science and more reliable evidence for computationally-driven practice and helps to adhere to new standards and guidelines of codesharing mandated by publishers and funding bodies.

On the Mathematical Foundation of a Decoupled Directional Distortional Hardening Model for Metal Plasticity in the Framework of Rational Thermodynamics

This study proposes a modification to the yield condition that addresses the mathematical constraints inherent in the Directional Distortional Hardening models developed by Feigenbaum and Dafalias. The modified model resolves both the mathematical inconsistency found in the complete model and the limitations of the r-model. In the complete model, inconsistency arises between the distortional term in the yield surface and the plastic part of the free energy in the absence of kinematic hardening. Additionally, the r-model fails to capture the flattening of the yield surface in the reverse loading direction due to the absence of a fourth-order anisotropic tensor structure in the distortional term. To address these issues, the proposed model introduces a decoupled distortional hardening term in the yield function. This modification enables the simultaneous representation of both flattening and sharpening of the yield surface, and permits isotropic hardening with distortion even without kinematic hardening. A consistent mathematical formulation based on rational mechanics and a corresponding numerical algorithm are also developed, establishing a foundation for future experimental investigations and model validation.

Assessment of Consumers Awareness of Nutrition, Food Safety and Hygiene in the Life Cycle for Sustainable Development of Bangladesh- A Study on Sylhet City Corporation

The objective of the study is to explore the knowledge of consumers on nutrition, food safety and hygiene of the sampled respondents in the Sylhet City Corporation in Bangladesh in terms of different demographic characteristics. This study includes the different types of consumers in the life cycle viz. baby, child, adolescent, young and old so that an overall awareness level can be measured in the urban area of Bangladesh. The study is confined to SCC area in which all types of respondents has been included and findings from this study will be used generally for Bangladesh in making policy In conducting the study the population has been divided into six group as, Baby, child, adolescent, parental, unmarried adult young and married adult matured. We find that the average score of awareness of food nutrition and hygiene of unmarried adult is higher than that of married adults. The study suggested it is needed to increase awareness in of the parents for feeding babies. The average awareness of parents to their childs eating behavior between 5 and 9 years is 3.36 out of 5. The awareness is around 67 percent so we should be more careful in this regard. The average awareness adolescent food habit is 1.89 on three points scales which about 63 percent only. Therefore, the consciousness of adolescent has been to increase in taking food. The average feeding styles of parents is 4.24 out of 5 to their children up to 9 years and in percentage it is 84 percent.

Vicious Cycle of Poverty in Haor Region of Bangladesh- Impact of Formal and Informal Credits

This research attempts to explore the key research questions about what are the different microcredit programs in Haor area in Bangladesh? And do microcredit programs have a positive impact on livelihoods of the clients in terms of selected social indicators viz. income, consumption, assets, net worth, education, access to finance, social capacity, food security and handling socks etc. in Haor area in Bangladesh? Utilizing difference-in-difference and factor analysis, we explore the nature and terms of conditions of available formal and informal micro-creditss in Haor region of Bangladesh; and investigate the impact of micro-creditss on the poverty condition of Haor people in Bangladesh. The findings showed that total income of borrowers has been increased over non-borrowers (z=6.75) significantly. Among the components of income, non-agricultural income has been increased significantly on the other hand income from labor sale has been decreased significantly. Total consumption expenditure with its heads of food and non-food consumption of both formal borrowers and informal borrowers have been increased over the period 2016-2019 significantly. Most of the key informants agreed that the findings are very much consistent with prevailing condition of micro-credits in Haor region. However, some of them raised question about the impacts of micro-credits. They argued that there is no straightforward positive impact of micro-credits on poverty condition of the households.

Impact of micro-credit on the livelihoods of clients -- A study on Sunamganj District

The objective of this paper is to assess the impact of micro credit on the livelihoods of the clients in the haor area of Sunamganj district, Sylhet, Bangladesh. The major findings of the study are that 66.2 percent respondents of borrowers and 98.7 non-borrowers are head of the family and an average 76.6 percent and among the borrowers 32 percent is husband/wife while 1.3 percent of non-borrowers and on average 22.2. In terms of sex 64.7 percent of borrowers and 92.5 percent of non-borrowers are male while 35.3 percent of borrowers and 7.5 percent of non-borrowers are female. The impact of micro-credit in terms of formal and informal credit receiving households based on DID method showed that total income, total expenditure and investment have been increased 13.57 percent, 10.39 percent and 26.17 percent. All the elements of total income have been increased except debt which has been decreased by 2.39 percent. But the decrease in debt is the good sign of positive impact of debt. Consumption of food has been increased but non-food has been decreased. All the elements of investment have been increased except some factors. The savings has been decreased due excess increase in investment. The study suggested that for breaking vicious cycle of poverty by micro-credit the duration of loans should be at least five year and the volume of loans must be minimum 500,000 and repayment should at not be less than monthly. The rate of interest should not be more than 5 percent.

Corporate Environmental Management Accounting Practicing and Reporting in Bangladesh

In the management of environment the Environmental Management Accounting (EMA) is essential for corporate or companies because corporate sectors are the main parties of environmental humiliation as they are existed in the environment and for protecting environment a branch of accounting is emerged which is called environmental management accounting. The objective of the study is to develop a compliance framework for EMA and appraise the ER practices in selected industries in Bangladesh. In conducting the study, 50 environmental sensitive industries were selected from DSE. A compliance checklist was developed on 75 aspects of EMA and ER under 13 groups. In developing the compliance index binary method is used i.e. 1= if ER practices; 0= if not practices. Further the level of EMR/ER practices have been evaluated in terms of selected independent variables of the company viz. total assets, total sales, return on equity and size of board. The study found that the environmental management accounting in the manufacturing companies is in poor level. The maximum compliance is 67% and the lowest is 20%. The TA, TS BS and SP have been considered to find out the explanatory variables. In most of the cases board size does not play significant role in the practice of EMA in the sampled firms.

Enhancing Software Development Process Using Automated Adaptation of Object Ensembles

Software development has been changing rapidly. This development process can be influenced through changing developer friendly approaches. We can save time consumption and accelerate the development process if we can automatically guide programmer during software development. There are some approaches that recommended relevant code snippets and APIitems to the developer. Some approaches apply general code, searching techniques and some approaches use an online based repository mining strategies. But it gets quite difficult to help programmers when they need particular type conversion problems. More specifically when they want to adapt existing interfaces according to their expectation. One of the familiar triumph to guide developers in such situation is adapting collections and arrays through automated adaptation of object ensembles. But how does it help to a novice developer in real time software development that is not explicitly specified? In this paper, we have developed a system that works as a plugin-tool integrated with a particular Data Mining Integrated environment (DMIE) to recommend relevant interface while they seek for a type conversion situation. We have a mined repository of respective adapter classes and related APIs from where developer, search their query and get their result using the relevant transformer classes. The system that recommends developers titled automated objective ensembles (AOE plugin).From the investigation as we have ever made, we can see that our approach much better than some of the existing approaches.
