The aim of this study was to explore the caregiving situation and subjective burden of informal caregivers of older family members during COVID-19, and to investigate how a caregiving situation’s characteristics predict the subjective burden of care in times of COVID-19. The study was conducted in April and May 2021 via an online access panel. The sample (n = 612) was determined using a screening test that enabled us to focus on a Slovenian population of informal caregivers aged 40+ caring for a person aged 65+ for at least four hours/week on average. Our findings reveal that the subjective burden of care was high among informal caregivers during COVID-19. Multiple regression analysis showed that the provision of activities of daily living, care duration, average hours of care per week, formal care status, and recipients’ health problems related t...

Prepisovanje podatkov iz ene aplikacije v drugo je nedopustno, saj se pri tem dogajajo napake, ki ogrožajo paciente. Ker želimo omogočiti avtomatski prenos podatkov iz ene v drugo aplikacijo, se je potrebno osredotočiti na zagotavljanje sintaktične in semantične interoperabilnosti. V članku prestavljamo primer integracije dveh zdravstvenih aplikacij v Angliji. Angleški NHS pri prenosu podatkov narekuje uporabo podatkovnih elementov standarda FHIR, s čimer dosežemo sintaktično interoperabilnost. Da bi dosegli semantično interoperabilnost, je potrebno zagotoviti, da se pomen konteksta pri prenosu ne spremeni. Cilja našega članka sta dva. Prvi je predstaviti predlog preslikave podatkovnih elementov iz standarda openEHR v integracijski standard imenovan FHIR. Drugi je ugotoviti, s katerimi izzivi se soočajo programerji ob uporabi standarda FHIR. V članku smo predstavili, kako angleška skupnost INTEROPen promovira uporabo razširj...

The ecosystem is able to orchestrate workflow between applications to make healthcare processes more effective and efficient. The ecosystem is gradually evolving as applications from different vendors can share the common data repository in the platform, as well as to collaborate and exchange patient data. With a marketplace of applications, the ecosystem can provide competition between applications and enable their seamless substitution. The use of a national healthcare ecosystem is still rare in practice today. Once the open platform is implemented its ecosystem needs time to evolve and demonstrate the expected benefits. Little is known about what a national healthcare ecosystem needs to mature. We present a case study of the Slovenian healthcare ecosystem, and discuss ou...

Design/methodology/approach–Combined with elements of action research, a longitudinal case study of implementing a wiki in a department of a Slovenian company was conducted. Interviews, surveys and a log analysis were used for the data collection. The Delone and McLean information systems success model was the underlying theoretical approach to explore the information, ...

Several case studies show that such undertakings may be promising at first glance, but often amount to little. More attention has to be paid to the factors that influence the business value of a social media application. The paper proposes a framework which argues that the business value of a social media activity depends on having a correctly identified purpose of its implementation (scope and targeted benefits), on the technological solution and also on user involvement (user groups, users’ motivation and skills). The framework is evaluated with a longitudinal case study of a wiki in a software development company where an assessment of the business value of the wiki at two different points in time was made. The case study shows how the interplay of components led to failure at one time point and success at the other.

Every good user story has to be independent, negotiable, valuable, estimable, small, and testable. A proper understanding of a user story also requires an understanding of its dependencies. The lack of explicit representation of such dependencies presumably leads to missing information regarding the context of a user story. ObjectiveWe propose a method that facilitates better understanding of execution order and integration dependencies of user stories by making use of business process models. The method associates user stories with the corresponding business process model activity element. MethodWe adopted a situational method engineering approach to define our proposed method. In order to provide understanding of proposed method's constructs we used ontological concepts. Our method associates a user story to an activity element. In this way, the business process model can be used to infer information about the execution order and integration dependencies of the user story. We defined three levels of association granularity: a user story can be more abstract, approximately equal to, or more detailed than its associated business process model activity element. In our experiment we evaluate each of these three levels. ResultsOur experiment uses a between-subject design. We applied comprehension, problem-solving and recall tasks to evaluate the hypotheses. The statistical results provide support for all of the hypotheses. Accordingly, there appears to be significantly greater understanding of the execution order and integration dependencies of user stories when associated business process models are available. ConclusionsWe addressed a problem which arises from managing user stories in software development projects and focuses on the missing context of a user story. Our method contributes to the discipline of conceptual modeling in agile development. Our experiment provides empirical insight into requirement dependencies.

However, often only the implementation of an information system is studied without analysing the consequent effects on its adoption and later use. Our paper uses actor network theory to show how successful implementation and adoption can lead to a low level of later use and lack of achievement of the declarative goals. The same actors may form networks leading to a successful outcome in one particular situation but not in another. In such a way seamless implementation can hinder the subsequent use and hide problems from the management. An analysis of a case study of an information system's implementation, adoption and later use in a primary school allows a better understanding of the reasons for the subsequent low use.

The development of complex ICT systems requires skilled ICT professionals who are often difficult to acquire. In this paper, we address this specific issue of transition economies and propose a novel global software development approach that aims to compensate for the lack of skilled ICT professionals by outsourcing independent development tasks globally to remote developers. The proposed approach was empirically tested in a pilot study at three different locations at University of Ljubljana in Slovenia. The test demonstrated the feasibility of the approach and indicated that task specification quality and developer skills are important success factors. The findings of the pilot study are primarily relevant for software development companies in transition economies even though the approach may also be applicable in other settings where lack of locally accessible skilled ICT professionals is present.

Approaches for eliciting user stories from customer’s existing documentation are missing. Furthermore, proper understanding of user story’s context requires an understanding of execution-order and integration dependencies among user stories, which are also missing. In this thesis we propose so-called BuPUS method which 1) facilitates elicitation of user stories from existing business process models, and 2) supports better understanding of execution-order and integration dependencies among user stories from customer’s existing documentation. The method associates user stories with corresponding BPMN’s activity elements, or with corresponding text-written use case model’s events. We defined three levels of association granularity: a user story can be more abstract, approximately equal to, or more detailed than its associated business process model’s event/activity element.

Software companies embracing global software engineering can benefit from it by wisely approaching its challenges. This paper gives a literature review on general GSD's challenges by examining how the focus changed in the last decade. There exist some global software development approaches that focus on overcoming these challenges. For example, the loosely coupled team approach helps to overcome the coordination issues that the virtual teams have to deal with by modularization of development work. However, none of these approaches is focused on supporting the development project with scattered individual developers.
