Pathways to energy autonomy – challenges and opportunities

The need to reduce carbon emissions calls for more use of renewable generation, particularly distributed resources. The intermittency of renewable generation, and concerns about energy security, require us to become more independent of central grid operation by use of local or regional (micro-grid) electricity systems. Distributed generation, allied to the commercial availability of battery storage products, permits this–the pathway to energy autonomy. This paper reviews the contribution of different renewable energy sources (RES), trends in energy storage technologies to enable energy autonomy, and the centralised and decentralised techniques that coordinate the associated energy management. The paper covers energy autonomy at different scales, ranging from household levels to district levels. The improvements in grid independency are measured accordingly. There is discussion of this measurement and of the economic and ecological benefits from energy autonomy in the context of policy frameworks.

Characteristics of high performance organization and knowledge productivity of independent professionals

High Performance Organization (HPO) characteristics indicate why an organization is able to achieve significantly better results than other organizations and these characteristics can facilitate associations to optimize employees’ work outcomes. The independent professional (IP) is an increasingly occurring phenomenon in the labor market that fulfils an organizations’ need for flexibility in knowledge productivity. This study focuses on the contribution of HPO characteristics to the knowledge productivity of IP's. It was conducted among managers and HRM professionals in various Dutch knowledge-intensive organizations that frequently enlist the services of IPs. This study found a number of HPO attributes that appeared to contribute to the IPs' knowledge productivity, namely the quality of management, an open and actionfocused organizational culture, and continual improvement and innovation. We will use these results to look ahead and consider the future consequences for professional practice. Managers and HRM professionals should strive to contribute to the incorporation of these characteristics within the organization in order to safeguard and enhance knowledge productivity of independent professionals.

Enabling older people to live independently

Discriminative validity of the Core outcome set functional independence in a population of older adults

Background: Clinicians are currently challenged to support older adults to maintain a certain level of Functional Independence (FI). FI is defined as "functioning physically safely and independent from another person, within one's own context". A Core Outcome Set was developed to measure FI. The purpose of this study was to assess discriminative validity of the Core Outcome Set FI (COSFI) in a population of Dutch older adults (≥ 65 years) with different levels of FI. Secondary objective was to assess to what extent the underlying domains 'coping', 'empowerment' and 'health literacy' contribute to the COSFI in addition to the domain 'physical capacity'. Methods: A population of 200 community-dwelling older adults and older adults living in residential care facilities were evaluated by the COSFI. The COSFI contains measurements on the four domains of FI: physical capacity, coping, empowerment and health literacy. In line with the COSMIN Study Design checklist for Patient-reported outcome measurement instruments, predefined hypotheses regarding prediction accuracy and differences between three subgroups of FI were tested. Testing included ordinal logistic regression analysis, with main outcome prediction accuracy of the COSFI on a proxy indicator for FI. Results: Overall, the prediction accuracy of the COSFI was 68%. For older adults living at home and depending on help in (i)ADL, prediction accuracy was 58%. 60% of the preset hypotheses were confirmed. Only physical capacity measured with Short Physical Performance Battery was significantly associated with group membership. Adding health literacy with coping or empowerment to a model with physical capacity improved the model significantly (p < 0.01). Conclusions: The current composition of the COSFI, did not yet meet the COSMIN criteria for discriminative validity. However, with some adjustments, the COSFI potentially becomes a valuable instrument for clinical practice. Context-related factors, like the presence of a spouse, also may be a determining factor in this population. It is recommended to include context-related factors in further research on determining FI in subgroups of older people.

Functional Independence in the Community Dwelling Older People: a Scoping Review

Ageing potentially poses a threat to independent functioning of older adults. Although clinicians commonly focus on physical factors limiting Functional Independence (FI), it is likely that personal and environmental interactions also seem important to maintain FI. Herewith, FI exceeds several professional borders and calls for a uniform, multidisciplinary interdisciplinary supported definition of FI. This study aims to provide such a definition of FI in community dwelling older people. A scoping review was performed. Pubmed/Medline, Psychinfo and CINAHL were searched for studies describing aspects of FI. A literature-based definition of FI was discussed by experts (n = 7), resulting in a formulated final definition of FI and insight into contributing factors to FI. A multidisciplinairy focusgroup a stakeholder consultation (n = 15) ensured clinical relevance for daily practice. Data from the focusgroup stakeholder consultation were analyzed by using Atlas.ti (version 8). Based on the literature search, 25 studies were included. FI was finally defined as “Functioning physically safely and independent from another person, within one’s own context”. The contributing factors of FI comprised physical capacity combined with coping, empowerment and health literacy. Moreover, the level of FI is influenced by someone’s own context. This study confirms the relevance of the physical aspect of FI, but additionally stresses the importance of psychological factors. In addition, this study shows that one’s context may affect the level of FI as well. This underlines the importance of a holistic view and calls for multidisciplinary interdisciplinary collaboration in community-dwelling older people.
