The Financial Case for Food as Medicine: Introduction of a ROI Calculator

Diet quality is now established as the single leading predictor of perennial premature death in modern countries. However, practice at scale in modern medicine is driven as much by financial as clinical imperatives and yet, the ability to quantify the potential ROI of Food as medicine (FaM) interventions is limited by a lack of data. Utilizing a novel advance in dietary assessment and data from the peer-reviewed literature, we constructed and tested a web-based calculator simulating the return-on-investment associated with FaM interventions.

“…However, with often limited resources and underdeveloped IT competences in their human resources departments, it is challenging for SMEs to carry this out in a cost-efficient and effort-reducing way. This can be achieved, among other methods, by screening the company's own HR data using AI-based software tools (e.g., text mining tools), which are available as open source, freemium (Chełkowski et al, 2021), or fully functional commercial software.…”

The purpose of this study is to answer the question of what options companies have when competing for digital talent. SMEs in particular, with their limited resources and significant backlog in terms of the digitalisation of corporate processes, find themselves in a digital talent trap which threatens to grow ever larger as digitalisation progresses. In other words, the digital talent gap could become a digital talent trap for SMEs in terms of digitalisation. The aim of this work is to derive from this insight a pragmatic and costeffective solution which, in addition to the highly competitive "buy" option -i.e., classic recruitment via the labour market -offers a "make" option for SMEs that focuses more on their own employee resources.The research approach was based on two steps. In the first step, various literature approaches for recording and measuring digital skills were analysed in order to summarise them and derive potential digital talent profiles. The second step was to search for suitable software packages that are able to detect these profiles or skills in company documents. With these data sets, an analysis was carried out in the third step using AI algorithms -created in Python -in order to identify potential digital talents. An anonymised personal data set was used to test the above decision-making process.The findings show that SMEs could already access powerful, user-friendly and low-cost digital AI tools when searching for digital talent -especially in the search for digital talents within the company. The assumption that only larger companies with the corresponding financial resources can afford this option cannot be confirmed.The originality of the work lies in the finding that suitable AI tools exist for SMEs to search for digital talent, but that these are not currently being used extensively. Barriers such as prohibitively high costs or the low user-friendliness of AI tools could not be confirmed within the scope of this study.

“…As these systems are open source, these are developed and maintained by multiple developers which reduces the biasness in terms of programming style (e.g. copy paste activity) which may occur in case of a single developer [34][35][36]. Our selected systems are well known systems and have been studied previously for clone research.…”

Historical perspective of code clone refactorings in evolving software

et al. 2022

Cloning in software is generally perceived as a threat to its maintenance and that is why it needs to be managed properly. Understanding clones from a historical perspective is essential for effective clone management. Analysis of code refactorings performed on clones in previous releases will help developers in taking decisions about clone refactoring in future releases. In this paper we perform a longitudinal study on the evolution of clone refactorings in various versions of five software systems. To perform a systematic study on clone refactoring evolution, we define clone evolution patterns for studying refactorings in a formal notation. Our results show that only a small proportion of code clones are refactored between the versions and most of the refactorings are inconsistent within clone classes. Moreover, clone refactorings may cause clone removal. Analysis of the source code of refactored clones reveals similar reasons of inconsistent refactorings and clone removal for five Java systems. This analysis will help in devising appropriate strategies for managing clone refactorings in software and hence provide foundation for devising better clone management tools.
