- Biomass is defined as organic matter from living organisms represented in all kingdoms. It is recognized to be an excellent source of proteins, polysaccharides and lipids and, as such, embodies a tailored feedstock for new products and processes to apply in green industries. The industrial processes focused on the valorization of terrestrial biomass are well established, but marine sources still represent an untapped resource. Oceans and seas occupy over 70% of the Earth's surface and are used intensively in worldwide economies through the fishery industry, as logistical routes, for mining ores and exploitation of fossil fuels, among others. All these activities produce waste. The other source of unused biomass derives from the beach wrack or washed-ashore organic material, especially in highly eutrophicated marine ecosystems. The development of high-added-value products from these side streams has been given priority in recent years due to the detection of a broad range of biopolymers, multiple nutrients and functional compounds that could find applications for human consumption or use in livestock/pet food, pharmaceutical and other industries. This review comprises a broad thematic approach in marine waste valorization, addressing the main achievements in marine biotechnology for advancing the circular economy, ranging from bioremediation applications for pollution treatment to energy and valorization for biomedical applications. It also includes a broad overview of the valorization of side streams in three selected case study areas: Norway, Scotland, and the Baltic Sea.

- In recent years, there has been an increased interest within the program evaluation field in the introduction of systems thinking concepts. However, most of these introductions have been primarily directed towards supporting the practice of evaluation and not towards making theoretical advancements. This article is focused on introducing systems thinking, and specifically perspectives and concepts from the work in critical systems thinking (CST), at a theoretical level in the program evaluation field, towards a reframing of Fourth Generation Evaluation methodology. The process for carrying out such a reframing is introduced, as well as a description of the major changes produced in the evaluation methodology from incorporating the CST perspective. A new model is proposed, and how this model may be beneficial for conducting an evaluation is discussed. Finally, recommendations are made for future developments.

The diversity and welfare of older migrants in Europe

Tidskriftsartikel (refereegranskat)abstract
- This paper sets the scene and provides a conceptual framework for the articles in this special issue. They present the findings of research on European residents who have reached or are on the threshold of old age and whose current circumstances have been strongly influenced by a migration across an international border. Such 'older migrants' are scattered throughout Europe and they have especially diverse characteristics. They include some of the most deprived and socially excluded, and some of the most affluent and accomplished, but all to a greater or lesser extent arc disadvantaged through an interaction between social policies and their 'otherness' by living in a foreign country. Some claim attention through the severity of their unmet health and welfare needs and poor capacity to access advice and treatment, while the affluent groups are of great interest to social gerontology because of their enterprising, developmental and positive approaches to old age. They include among the most innovative of the latest generation of older people, who pursue new combinations of family responsibilities, leisure pursuits and income generation. The paper proposes that the concept 'human capital' summarises variations in preparedness for old age, that is, the resources by which people cope with demands for income, roles, treatment, care and support. A typology of the 'welfare position' of international migrants in contemporary Europe is presented.
