Construction firms keep minimal resources to maintain productive working capital. Hence, resources are constrained and have to be shared among multiple projects in an organization. Optimal allocation of resources is a key challenge in such situations. Several approaches and heuristics have been proposed for this task. The purpose of this paper is to compare two approaches for multi-mode resource-constrained project scheduling in a multi-project environment. These are the single-project approach (portfolio optimization) and the multi-project approach (each project is optimized individually, and then heuristic rules are used to satisfy the portfolio constraint).

A direct search algorithm called Probabilistic Global Search Lausanne is used for schedule optimization. Multiple solutions are generated that achieve different trade-offs among the three criteria, namely, time, cost and quality. Good compromise solutions among these are identified using a multi-criteria decision making method, Relaxed Restricted Pareto Version 4. The solutions obtained using the single-project and multi-project approaches are compared in order to evaluate their advantages and disadvantages. Data from two sources are used for the evaluation: modified multi-mode resource-constrained project scheduling problem data sets from the project scheduling problem library (PSPLIB) and three real case study projects in India.

Computational results prove the superiority of the single-project approach over heuristic priority rules (multi-project approach). The single-project approach identifies better solutions compared to the multi-project approach. However, the multi-project approach involves fewer optimization variables and is faster in execution.

It is feasible to adopt the single-project approach in practice; realistic resource constraints can be incorporated in a multi-objective optimization formulation; and good compromise solutions that achieve acceptable trade-offs among the conflicting objectives can be identified.

An integer programming model was developed in this research to optimize the multiple objectives in a multi-project environment considering explicit resource constraints and maximum daily costs constraints. This model was used to compare the performance of the two multi-project environment approaches. Unlike existing work in this area, the model used to predict the quality of activity execution modes is based on data collected from real construction projects.

The purpose of this paper is to use a descriptive case study to establish how collaboration, innovation and knowledge‐management strategies have scaled‐up learning and development in rural, remote and other resource‐constrained Canadian delivery settings.

Intervention design was realized through a one‐time, collaborative, national capacity‐building project. A project portfolio of 72 sub‐projects, initiatives and strategic activities was used to improve access, enhance quality and create capacity for palliative and end‐of‐life care services. Evaluation was multifaceted, including participatory action research, variance analysis and impact analysis. This has been supplemented by post‐intervention critical reflection and integration of relevant literature.

The purposeful use of collaboration, innovation and knowledge‐management strategies have been successfully used to support a rapid scaling‐up of learning and development interventions. This has enabled enhanced and new pan‐Canadian health delivery capacity implemented at the local service delivery catchment‐level.

The intervention is bounded by a Canada‐specific socio‐cultural/political context. Design variables and antecedent conditions may not be present and/or readily replicated in other nation‐state contexts. The findings suggest opportunities for future integrative and applied health services and policy research, including collaborative inquiry that weaves together concepts from adult learning, social science and industrial engineering.

Scaling‐up for new capacity is ideally approached as a holistic, multi‐faceted process which considers the total assets within delivery systems, service catchments and communities as potentially being engaged and deployed.

The Pallium Integrated Capacity‐building Initiative offers model elements useful to others seeking theory‐informed practices to rapidly and effectively scale‐up learning and development efforts.

This paper examines the predictive role of personality traits on the entrepreneurial bricolage behaviour of female entrepreneurs in a resource-constrained setting.

Data were collected using a structured survey questionnaire from female entrepreneurs owning and operating micro-small firms. The analysis and hypotheses testing were performed adopting SEM-PLS3.0 software.

The results showed that all dimensions of the Big Five personality traits significantly influence entrepreneurial bricolage. In addition, agreeableness, conscientiousness, and intellect were found to be the most important traits in female entrepreneurs for bricolage behaviour.

The results can help provide a better understanding of the linkages between entrepreneurial traits and bricolage. Development agencies may take up this result to ensure the appropriate social inclusion by supporting female entrepreneurs.

To the authors' best knowledge, this paper is the first empirical study that has investigated the relationship between personality traits and entrepreneurial bricolage.

This paper aims to report a non-randomized control study undertaken to investigate prevalence and correlates of conduct disorder among male secondary education students in South-West Nigeria and to assess the impact of a problem-solving skills and attributional retraining (PSSAR) intervention with this population.

In total, 787 male students from two schools were screened for conduct disorder. All participants who met criteria for the disorder were allocated to either treatment (n = 55) or control (n = 47) groups. Outcome measures comprised the strengths and difficulties questionnaire (SDQ; teacher and student versions) and the teacher rating of students’ aggressive behaviors.

Of the sample, 13% were found to present with difficulties that met criteria for conduct disorder. The presence of these difficulties correlated with several demographic variables, including parental conflict and alcohol use. A statistically significant reduction in mean scores was observed for the treatment group in the student rating of the SDQ emotional subscale and total difficulties scores. Teacher ratings were less consistent in that conduct problems, prosocial behavior and total difficulties increased following the intervention, whereas peer problems and aggressive behavior were reported by teachers to reduce. No statistically significant change was found in the outcome measures for the control group.

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed.

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed. This study’s findings offer some preliminary support for the PSSAR intervention for conduct disorder in this context and indicate areas for further research.

This paper to examine the relationship between performance expectancy and behavioural intention to use mobile-based communication technologies for agricultural market information dissemination in Uganda.

A descriptive field survey method was adopted. A total of 302 commercial farmers and agribusiness traders in Eastern Uganda participated in the study from whom data were collected using self-administered questionnaires. Descriptive statistics, factor analysis, correlation and regression analyses were used in the study.

The findings reveal a significant positive relationship between performance expectancy and behavioural intentions to use mobile-based communication technologies for agricultural information access and dissemination. This implies that, commercial farmers’ behavioural intentions to use mobile-based communication technologies for agricultural market information dissemination and access will be influenced if they anticipate mobile-based communication technologies to offer greater performance in their daily transactions.

This study was conducted in the context of resource constrained countries particularly in sub-Saharan Africa, however reflecting knowledge from other contexts. The study was conducted with a structured questionnaire being the main data collection tool, and this limited the study from collecting views outside the questions asked in the questionnaire. The variables studied could not be analysed for a long time, given that the study was cross-sectional in nature.

The study provides recommendations on how to further boost farmers’ behavioural intentions to use mobile-based communication technologies for agricultural information dissemination. Policy makers need to ensure that policies are put in place that encourage third party software developers and telecommunication companies to provide software products and solutions that are beneficial to the commercial farmers and can enable them complete their agricultural transactions in time.

The study provides critical literature on the influence of performance expectancy on commercial farmers’ behavioural intentions to use mobile-based communication technologies for agricultural market information access and dissemination in resource constrained settings.

It is noted that farmers in Uganda are slowly progressing to newer mobile information and communication technology tools for market information access and dissemination; however, little is known as to why there is slow adoption of these mobile technologies for agricultural purposes; yet policy makers need to come up with proper strategies to encourage wide scale use of mobile technologies for agricultural market purposes.

The purpose of this paper is to provide an “inside” account of efforts to enhance the quality of care in a paediatric hospital department in Malawi.

The authors describe the problems they face as health workers in an overcrowded, under-resourced emergency departments in a low-income setting. Where it is helpful, the authors combine reports of their experience with reference to reports emanating from other African countries.

There is increased awareness of the need for a good health system to be able to provide quality care. The authors emphasise the importance of teamwork and the need for cross cutting activities that are not disease-centred or vertically driven. Task sharing and multi-tasking have helped fill the gaps left by inadequate staffing but specialists in emergency medicine are needed to advocate for the specialty and be role models in departments.

This paper is aimed at a broad audience of fellow clinicians, funders and policy makers, and those who have an interest in clinical governance in support of quality improvement in developing countries.

This is a firsthand account of efforts to enhance the quality of emergency care from a paediatric hospital department in Malawi.

This paper aims to investigate the entrepreneurial behaviours exhibited by commercial smallholder farmers in Zimbabwe, focusing on their socio-economic characteristics, and considers their implication for outcomes of livelihood resilience in a resource-constrained and turbulent rural context.

The study used survey data collected from 430 smallholder farmers in Masvingo province, Zimbabwe. Using a two-step cluster analysis, the study constructed a typology of farmers based on their entrepreneurial behaviour and socio-economic characteristics.

The results revealed that commercial smallholder farmers are heterogeneous in terms of their entrepreneurial behaviours. Four clusters were identified: non-entrepreneurial, goal-driven, means-driven and ambidextrous. Beyond their entrepreneurial behaviours, these clusters significantly differ in the socio-economic characterises (gender, age, education levels, farm size, proximity to the market and social connection) and farm performance (seasonal sales per hectare and farm income per hectare).

The typology framework relating farmers’ entrepreneurial behaviours to their socio-economic characteristics and business performance is important to tailor and therefore improve the effectiveness of farmer entrepreneurship programmes and policies. In particular, tailoring farmer entrepreneurship education is crucial to distribute land, finance and market resources in purposive ways to promote a combination of smallholder farmers’ effectual and causal behaviours at an early stage of their farm ventures.

Researchers still know little about which farmers’ behaviours are entrepreneurial and how these behaviours manifest in action during their commercial farm activities. This research leverages effectuation and causation theory to unveil previously overlooked distinctions on farmers’ entrepreneurial behaviours, thereby enhancing a more grounded understanding of farmer entrepreneurship in a resource-constrained context.

Delivering housing to resource-constrained communities (RCCs) is a complex process beset with difficulties. The purpose of this study is to use a complexity lens to examine the approach taken by a social enterprise (SE) in Australia to develop and manage a housebuilding supply chain for RCCs.

The research team used a longitudinal case study approach from 2017 to 2022, which used mixed methods to understand the phenomenon and gain an in-depth understanding of the complex issues and problem-solving undertaken by an SE start-up.

Balancing mission logic with commercial viability is challenging for an SE. The supply chain solution that evolved accommodated the particulars of geography and the needs of many stakeholders, including the end-user community and government sponsors. Extensive and time-consuming socialisation and customisation led to a successful technical design and sustainable supply chain operation.

Analysing supply chain intricacies via a complexity framework is valuable for scholars and practitioners, assisting in designing and developing supply chain configurations and understanding their dynamics. Meeting the housing construction needs of RCCs requires the SE to place societal focus at the centre of the supply chain rather than merely being a system output. The developed business model complements the engineering solution to empower a community-led housing construction supply chain.

This longitudinal case study contributes to knowledge by providing rich insights into the roles of SEs and how they develop and operate supply chains to fit with the needs of RCCs. Adding a contextual response dimension to an established complexity framework helped to explain how hybrid organisations balance commercial viability demands with social mission logic by amending traditional supply chain and governance practices. The case provides insights into supply chain configuration, needed changes and potential impacts when an SE as a focal actor inserts into a traditional for-profit construction supply chain.

This paper presents a work-centred study of how information systems practices and tools become shaped by their context. The purpose of this paper is to increase the understanding of how practices and tools co-evolve, with a specific focus on the role of context, and based on this to offer relevant design implications. The empirical motivation comes from attempts to utilize information and communication technologies (ICT) in resource-constrained settings.

Empirical work was conducted in primary healthcare facilities in Tanzania that offer Prevention of Mother-To-Child Transmission services. Four health facilities with different organizational and socio-economic characteristics were studied using ethnographic methods (participant observation, interviews and document analysis). The authors have employed activity theory as the theoretical framework, since it explicitly places human activity within a cultural, social and temporal (developmental) context. Specifically, the concept of mediation breakdown was used for data analysis at activity, action and operation levels.

By focussing analytically on situations of mediation breakdown in the situation of use, at both an activity, action and operation level, the authors have achieved an understanding of how information tools are being adapted to both their contextual conditions and the information needs of the community of users.

The study illustrates the decisive role that context may play in shaping the actual usage of information technology. While the detailed findings were specific to the concrete domain, time and place, in general, an increased awareness of the role of context may lead to more robust approaches to the introduction of ICT solutions.

While activity theory literature offers insight on how to analyse context, the discussion is limited to the understanding of how context can be modelled into artefacts. The paper suggests that the contradiction concept is useful for studying the role of context and its impact in co-evolution of work and information tools. The study also contributes to the discourse in health information systems in developing countries by emphasizing the crucial role of the front line health workers’ own problem solving, invention and adaptation of information tools.

The health of people living in prisons (PLP) frequently remains marginalised in national development discourse, particularly in resource-constrained settings like Ghana. This study aims to determine the prevalence of cardiovascular disease (CVD) risk factors among PLP at a prison facility in the Northern Region of Ghana.

A cross-sectional study involving 134 male persons in prison, aged 18–79 years, was conducted to assess their dietary habits, tobacco use, alcohol consumption, sleep behaviour and physical activity practices. Serum lipid profile, fasting blood glucose (FBG), blood pressure (BP) and body mass indices of participants were also measured.

Almost half (48.1%) of the participants had abnormal lipid levels. Those with FBG in the diabetes range (= 7.0 mmol/l) constituted 3.9%, while 16.7% were in the impaired FBG range (6.1–6.9 mmol/l). Participants with BP within the pre-hypertension range were 54.5%. The majority of participants (92%) had a low daily intake of fruits and vegetables. Few participants were active smokers (5%) and alcohol users (2%). The average sleep duration at night among the participants was 5.54 ± 2.07 h. The majority (74%) of the participants were sedentary. About a quarter of the participants (24.6%) had overweight/obesity.

This study highlights the CVD risks among PLP. Findings suggest the need for targeted interventions, such as dietary and lifestyle modification strategies, regular physical activity and routine screening for diabetes, dyslipidaemia and hypertension. These interventions within the prison space could significantly improve the cardiovascular health of PLP in resource-limited settings.
