Assessment of the Physical Capabilities of Heart Failure Patients before and after Cardiovascular Rehabilitation: A Study of 125 Patients from West Africa, Dakar, Senegal

Background: Cardiac rehabilitation represents a critical therapeutic strategy for patients suffering from chronic heart failure. The physical capacity of patients with heart failure, assessed using the exercise test and the 6-minute walk test, is the measure of the patient’s overall functional ability to perform physical activities and tolerate exercise loads. The objective of this study was to assess the impact of cardiac rehabilitation on patients’ physical capabilities and to conduct a thorough comparison of data obtained via exercise testing and the 6-minute walk test before and after the rehabilitation programme. Methods: This was a descriptive and analytical cross-sectional study, conducted from 1 February 2021 to 31 June 2022. Included were heart failure patients who had participated in an outpatient cardiovascular rehabilitation programme. The collected data included anamnestic, clinical, paraclinical data, and the 6-minute walk test. Informed consent was obtained. Data analysis, word processing, and charting were performed using Microsoft Word 2016, Excel 2013, and Sphinx version 5.1.0.2. Data analysis was performed using SPSS (Statistical Package for Social Sciences) version 24.0. Any difference less than 0.05 was considered statistically significant. Results: In a Senegalese study, heart failure patients undergoing rehabilitation in a cardiac unit represented 45.59% of all cases, with a prevalence rate of 3.21%. The average participant was 57.97 years old, with those aged 61 to 70 forming the largest group (35.5%). The study noted a male predominance (sex ratio of 2.1) and identified dyslipidaemia (80.6%) and sedentarism (71%), as prevalent cardiovascular risk factors. All participants initially suffered from NYHA stage 2 or 3 dyspnoea, yet 80.65% showed no symptoms following rehabilitation. Significant improvements were recorded in resting heart rate (from 79 to 67 bpm), and the 6-minute walk test distance (from 328 m to 470 m). Enhanced exercise tolerance and walking test outcomes were particularly notable in patients with LVEF ≥ 50%, women, non-obese individuals, those initially walking less than 300 m, achieving more than 3 METs, and non-smokers. Conclusion: The findings underscore the effectiveness of cardiovascular rehabilitation in improving symptoms, physical capability, and overall quality of life for heart failure patients in Senegal.

Leveraging core capabilities and environmental dynamism for food traceability and firm performance in a food supply chain: A moderated mediation model

This paper develops a moderated mediation model in which the interactive effects of food traceability and environmental dynamism on firm performance are mediated by the core capabilities(operating capabilities and marketing capabilities)in food supply chain context, by invoking the indirect view of organizational learning theory. Our hypotheses were tested using hierarchical regression and bootstrapping methods with a sample of 216 food manufacturing firms in China, and a survey-based, two-informant design was used to collect data. The results revealed that operating and marketing capabilities fully mediate the food traceability-performance link. In addition, environmental dynamism positively moderates the food traceability-core capabilities link. Moreover, it is found that operating and marketing capabilities transform the interactive impacts of environmental dynamism and food traceability into firm performance. Our study offers a fine-grained picture of the essential food traceability-performance link by revealing for the first time that there is an interactive impacts of food traceability and environmental dynamism on firm performance via core capabilities.

Reflection and operationalization of the common but differentiated responsibilities and respective capabilities principle in the transparency framework under the international climate change regime

“Common but differentiated responsibilities and respective capabilities”(CBDRRC) is the most significant guiding principle in the international climate change regime, created by the United Nations Framework Convention on Climate Change in 1992 and inherited by the Paris Agreement 24 years later. This paper examines the operationalization of the CBDRRC principle in one of the cornerstone rules of the regimedits transparency provisions, both in existing practice under the convention and possible evolvement in negotiations under the Paris Agreement, from the perspectives of both international rule-making and domestic implementation. The authors have found a continuous enhancement of the transparency framework since the 1990s, and gradual consolidation of a bifurcated system between developed and developing countries into a common one. The authors argue that the transparency framework, as part of the procedural rules, should be designed to facilitate transparent information sharing in accordance with substantive commitments under international climate change laws. Thus, it indirectly reflects historical responsibilities for climate change, while the framework should also be designed as feasible and reflective of the respective capabilities of nations. Finally, the evolution of the transparency framework will aim to enact common and enhanced provisions while differentiating between developed and developing countries in the near term, and greater transparency-related capacity-building for developing countries.

Hydrogen storage capabilities of the most stable isomers of Na_nB_m(m+n=6) clusters

The most stable isomers of NanBm （m ＋ n = 6） clusters and their hydrogen storage properties are investigated by means of density functional theory with a 6-311＋G（d） basis set. To study the hydrogen storage properties, all of the stable structures of NanBmHx （m ＋ n =6） clusters have been optimized. It shows that boron atoms of NanBm are separated from the other boron atoms, and form satellite BHx （x = 3, 4） clusters around the centre, which attach to the system by a bridging bond of a hydrogen atom or an Na atom. Compared with the hydrogen storage capabilities, the Na3B3 has the highest hydrogen storage capacity among NanBm clusters. The binding energies, interaction energies of hydrogen atom with NanBm clusters and second difference in energy of Na3B3Hx clusters have been calculated. The results show that the stability of the NanBmHx clusters present an odd-even oscillatory effect, as the number of H atoms increases.

Academia Capabilities,Knowledge Transfer Programme Mechanism and Performance

Knowledge transfer(KT)is an attempt by an entity to copy and utilize an explicit type of knowledge from another entity.The main reason is none other than to expand the ability and increasing the value through inter-organization collaborative affiliation.Nonetheless,questions may arise as to what extent do capabilities,mechanism and performance or success is associated.Using inputs from 154 respondents which consist of various KTP(knowledge transfer program)partners namely from the community(total 94)and industry(total 60),this article highlights the associations between the three main categories of variables.Using Smart PLS(partial least squares),the study provides evidence that academia knowledge,academia readiness,academia skills,and ethics and conduct affect KTP performance through the mediation role of KT mechanism.Academia readiness was also found to be the most significant predictor to KT mechanism.In summary,all the significant capabilities have indirect positive impact towards KTP performance.Thus,higher education institutions must emphasize their internal strength in order to continue supporting the success of inter-organization collaborative affiliation.

Facilitating Multi-generational Talent Collaboration in a Context-Critical World Through Design Capabilities

One of the major concerns in today‘s business world is talent retention and development.Leading and working with multi-generational workforce in the age of digital transformation may seem daunting,but this paper argues that it has its advantages in creating opportunities.Through interviews and case studies,this paper discovers that tensions in multi-generational collaboration often occur during the process of setting priorities for a group because different generations might have brought in different levels of capacity and willingness to take risks,and different levels of trust in,and care for people and the organization.The role of design in this context focuses more on capabilities,including observing generational behavioral nuances through practicing empathetic view,inviting people from different age into conversation and actively listening to them through the practice of shifting perspectives,and communicating complex situations through visualization and materialization for people to feel together.If we look at different generations in an organization as natural continuum of knowledge flow,if we see multigenerational workforce as one of driving forces to maintain organizational balance rather than tearing forces,and if we approach generational attributes with honesty,we could steer away from stereotypes and find common grounds to thrive together.
