    Die Supply Chain von Algen in Indonesien, insbesondere Karrageen und Agarprodukte, ist mit Störungen innerhalb der Unternehmen und in externen Netzwerken konfrontiert wie z. B. QuantitĂ€t, QualitĂ€t, Preis und Infrastruktur. Sobald eine Störung in einem Teil der Supply Chain auftritt, kann diese die gesamte Wertschöpfungskette beeinflussen. Um eine nachhaltige Algenindustrie sicher zu stellen, bedarf es einer langzeitigen Planung. Hierbei kann das Supply Chain Risk Management (SCRM) helfen. SCRM umfasst vier kritische Stufen: Identifikation der Algen-Supply Chains, Identifikation und Kategorisierung der Risiken, EinschĂ€tzen der Risiken und Vermeidung der Risiken. Um die Algen-Supply Chains zu identifizieren, wurden Feldforschung, Tiefeninterviews und Literaturrecherchen durchgefĂŒhrt. Die Feldstudie wurde in den Provinzen SĂŒd-Sulawesi, West-Java, Ost-Java, Banten und West-Nusa Tenggara durchgefĂŒhrt. Anschließend wurden die Algen-Supply Chains mit der Software Umberto NXT Universal 7.0 modelliert, um ein besseres VerstĂ€ndnis von den Material- und EnergieflĂŒssen zwischen den Hauptakteuren zu erhalten. Um die Risiken zu identifizieren und zu kategorisieren wurden Literaturrecherchen durchgefĂŒhrt und die Delphi Methode angewandt, um potentielle Quellen der Risiken, ihre GrĂŒnde und ihre Effekte zu analysieren. Zur EinschĂ€tzung der Risiken wurde ein semi-quantitativer Ansatz gewĂ€hlt, welcher auf Face-to-face Interviews zurĂŒckgreift. Dementsprechend wurde eine Risikokarte erstellt, welche die Wahrscheinlichkeiten und Effekte von ungĂŒnstigen Ereignissen widerspiegelt. Basierend auf den vorherigen Ergebnissen wurde die IntensitĂ€t der Risiken in die folgenden fĂŒnf Kategorien unterteilt: vernachlĂ€ssigbare, geringe, kritische, sehr kritische und katastrophale Risiken. Drei alternative Strategien zur Vermeidung der Risiken werden vorgeschlagen: der Bau einer kleinen Algen-Fabrik, große Algen-Herstellung und industrielle Algen-Cluster, welche direkt am Algenanbau angegliedert sein mĂŒssen. Um die Strategien zu bewerten wurde die Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) angewandt, welche der multikriteriellen Entscheidungsanalyse zuzurechnen ist. Die Vermeidungsstrategien berĂŒcksichtigen  Nachhaltigkeitskriterien (Ökologie, Wirtschaft, Soziales) und Risikokriterien. Die Ergebnisse zeigen, dass Algen-Supply Chains mit vertikaler Kooperation, aus Algen-Lieferanten (Farmer, lokale HĂ€ndler, GroßhĂ€ndler und Exporteure) und Algen-Herstellern (Carrageen- und Agarunternehmen) bestehen. Die meisten Algen-Farmer sind unabhĂ€ngige Farmer, die die Möglichkeit haben die Algen entweder an lokale HĂ€ndler oder andere je nach PrĂ€ferenz verkaufen können. Lokale HĂ€ndler spielen eine entscheidende Rolle hinsichtlich der finanziellen UnterstĂŒtzung der Farmer, der technischen Informationen und des Marktzugangs. Indonesische Carrageen- und Agarhersteller weisen ein kontinuierliches Marktwachstum auf, insbesondere als Familienunternehmen. Die Risiken der Algen-Supply Chain werden in zwei Hauptkategorien unterteilt: interne und externe Risiken. Interne Risiken werden weiterhin in zwei Gruppen untergliedert: interne Unternehmensrisiken, welche aus Prozess- und Steuerungsrisiken bestehen, sowie externe Unternehmensrisiken, die Supply- und Nachfragerisiken umfassen. Externe Supply Chain Risiken, die aus externen Netzwerkketten resultieren, sind Risiken hinsichtlich regulatorischer Fragen, der Finanzierung, Infrastruktur als auch soziale und umweltbezogene Risiken. Als kritischstes Risiko fĂŒr die Carrageen-Supply Chain wurde die mangelnde QualitĂ€t von E.cottonii rohgetrockneten Algen identifiziert. Weitere kritische Risiken der Agar-Supply Chain sind QuantitĂ€tsunsicherheiten, die Knappheit von Gracilaria roh getrockneten Algen sowie negative Umweltauswirkungen des Abwassers. Aus  der Fallstudie zu halb-raffinierten Karrageen resultierte das Clustern von Algen-Verarbeitungsbetrieben als ist die beste Risikovermeidungsstrategie sowohl fĂŒr große als auch kleine Unternehmen. Nichtsdestotrotz kann sich das Clustern negativ auf die lokale Umwelt auswirken.

    Circular Economy put forth as an alternative to traditional linear model of extract-use-dispose along with the concept of Sustainable Development encompassing economic, environmental, and social aspects have garnered tremendous impetus among academics, practitioners and policymakers alike. The UN Sustainable Development Goals embraced by the member nations in 2015 based on the preceding Millenium Development Goals have been placed as the targets to be achieved as a part of holistic human development. In this backdrop, this paper examines the intersection of sustainability and circular economy with a focus on the three aspects of sustainable development, first the economic aspect by examining the relationship between GDP and circular economy, second the social economic aspect within the interaction of Circular Economy with Sustainable development and third the environmental-economical aspect by examining circularity and sustainability in waste management and waste valorisation. This paper achieves its objective through a systematic literature review of 1748 journal articles collected from Web of Science and SCOPUS database following PRISMA standards, network analysis of keywords, and manual review of texts. Four Research Questions are formulated: RQ1: What are the major emergent topics in Circular Economy and Sustainable Development and how are they related? RQ2: What is the relationship among CE and GDP in the CE and Sustainability? RQ3: What are the relationships between CE and Sustainability? RQ4: What are different use cases of valorisation of waste as CE tool, and can valorisation be sustainable? RQ1 is answered by presenting hotspot of research on Circular Economy and Sustainable Development through keywords occurrence network analysis using VosViewer. This study identifies three clusters and seven thematic areas of research, along with 25 most used keywords. RQ2 is attended through review of the relationship between economic growth (Gross Domestic Product) and Circular Economy and proposes based on the review that CE is still at its infancy. The paper also discusses the appropriateness of using GDP as a measure of sustainable development. This paper addresses RQ3 by examining the relationship between Circular Economy and Sustainable Development through review of literatures. The indicators used to measure CE and SD are also discussed and summarised. This review finds that achieving SDGs require greater effort, and that the present status of achievement is a bleak picture. Further, the role of waste management and potentiality of waste valorisation to aid in circular economy and sustainable development is analysed to answer RQ4. Though there are ample potential, however the recycle rate is very minimal to quench the required level of circularity. While CE and SD are related, CE cannot be a universal panacea to global challenges like emissions reduction, energy consumption, climate change, gender equality, poverty, well-being, environmental protection etc. even though the impact of CE to achieve SD can be substantial. The paper recommends avenues for future research and presents the conclusion of the study

    Background: Health care professionals are often reluctant to deprescribe fall-risk-increasing drugs (FRIDs). Lack of knowledge and skills form a significant barrier. To support clinicians in the management of FRIDs and to facilitate the deprescribing process, a deprescribing tool was developed by a European expert group for STOPPFall (Screening Tool of Older Persons Prescriptions in older adults with high fall risk) items. Methods: STOPPFall was created using an expert Delphi consensus process in 2019 and in 2020, 24 panellists from EuGMS SIG on Pharmacology and Task and Finish on FRIDs completed deprescribing tool questionnaire. To develop the questionnaire, a Medline literature search was performed. The panellists were asked to indicate for every medication class a possible need for stepwise withdrawal and strategy for withdrawal. They were asked in which situations withdrawal should be performed. Furthermore, panellists were requested to indicate those symptoms patients should be monitored for after deprescribing and a possible need for follow-ups. Results: Practical deprescribing guidance was developed for STOPPFall medication classes. For each medication class, a decision tree algorithm was developed including steps from medication review to symptom monitoring after medication withdrawal. Conclusion: STOPPFall was combined with a practical deprescribing tool designed to optimize medication review. This practical guide can help overcome current reluctance towards deprescribing in clinical practice by providing an up-to-date and straightforward source of expert knowledge

    Purpose: To explore the association between the number of medications and mortality in geriatric inpatients taking activities of daily living and comorbidities into account. Methods: A nationwide population-based cohort study was performed including all patients aged C65 years admitted to geriatric departments in Denmark during 2005-2014. The outcome of interest was mortality. Activities of daily living using Barthel-Index (BI) were measured at admission. National health registers were used to link data on an individual level extracting data on medications, and hospital diseases. Patients were followed to the end of study (31.12.2015), death, or emigration, which ever occurred first. Kaplan-Meier survival curves were used to estimate crude survival proportions. Univariable and multivariable analyses were performed using Cox regression. The multivariable analysis adjusted for age, marital status, period of hospital admission, BMI, and BI (model 1), and further adding either number of diseases (model 2) or Charlson comorbidity index (model 3). Results: We included 74603 patients (62.8% women), with a median age of 83 (interquartile range [IQR] 77-88) years. Patients used a median of 6 (IQR 4-9) medications. Increasing number of medications was associated with increased overall, 30-days, and 1-year mortality in all 3 multivariable models for both men and women. For each extra medication the mortality increased by 3% in women and 4% in men in the fully adjusted model. Conclusion: Increasing number of medications was associated with mortality in this nationwide cohort of geriatric inpatients. Our findings highlight the importance of polypharmacy in older patients with comorbidities

    Background: Dementia is a common condition in older people. Among the potential risk factors, increasing attention has been focused on sedentary behaviour. However, synthesizing literature exploring whether physical activity/exercise can affect health outcomes in people with dementia or with mild cognitive impairment (MCI) is still limited. Therefore, the aim of this umbrella review, promoted by the European Geriatric Medicine Society (EuGMS), is to understand the importance of physical activity/exercise for improving cognitive and non-cognitive outcomes in people with dementia/MCI. Methods: Umbrella review of systematic reviews (SR) (with or without meta-analyses) of randomized controlled trials (RCTs) and observational (prospective and case-control in people with MCI) studies based on a systematic literature search in several databases. The certainty of evidence of statistically significant outcomes attributable to physical activity/exercise interventions was evaluated using Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Among 1,160 articles initially evaluated, 27 systematic reviews (4 without meta-analysis) for a total of 28,205 participants with dementia/MCI were included. No observational study on physical activity/exercise in MCI for preventing dementia was included. In SRs with MAs, physical activity/exercise was effective in improving global cognition in Alzheimer’s disease and in all types of dementia (very low/low certainty of evidence). Moreover, physical activity/ exercise significantly improved global cognition, attention, executive function, and memory in MCI, with a certainty of evidence varying from low to moderate. Finally, physical activity/exercise improved non-cognitive outcomes in people with dementia including falls and neuropsychiatric symptoms. SRs, without meta-analysis, corroborated these results. Conclusions: Supported by very low to moderate certainty of evidence, physical activity/exercise has a positive effect on several cognitive and non-cognitive outcomes in people with dementia and MCI, but RCTs, with low risk of bias/confounding, are still needed to confirm these findings

    Dairy Sector: Opportunities and Sustainability Challenges

    Get PDF
    Achieving success along the entire production and supply chain of a dairy sector depends explicitly on adopting a sustainable 'state of the art' approach. In this regard, understanding key sustainability indicators and challenges with a holistic approach is vital. Appropriate design, application of novel technologies, implementation of life cycle analysis, upgradation and optimization of the entire production line are some of the key factors to be measured. In addition, it is vital that due consideration is given to demands of the producers, consumers, and dependent industries. Nevertheless, concern for the environment, social security and economy of the region should not be ignored. Precise planning ('on-farm' and 'off-farm') assumes importance especially when circular economy strategies needs to be considered. With these as background, this book is focused towards identifying present opportunities and overcoming future sustainability challenges in the global dairy sector
