Camera-based objective measures of Parkinson's disease gait features

OBJECTIVE: Parkinson's disease is a common, age-related, neurodegenerative disease, affecting gait and other motor functions. Technological developments in consumer imaging are starting to provide high-quality, affordable tools for home-based diagnosis and monitoring. This pilot study aims to investigate whether a consumer depth camera can capture changes in gait features of Parkinson's patients. The dataset consisted of 19 patients (tested in both a practically defined OFF phase and ON phase) and 8 controls, who performed the "Timed-Up-and-Go" test multiple times while being recorded with the Microsoft Kinect V2 sensor. Camera-derived features were step length, average walking speed and mediolateral sway. Motor signs were assessed clinically using the Movement Disorder Society Unified Parkinson's Disease Rating Scale. RESULTS: We found significant group differences between patients and controls for step length and average walking speed, showing the ability to detect Parkinson's features. However, there were no differences between the ON and OFF medication state, so further developments are needed to allow for detection of small intra-individual changes in symptom severity

The Importance of Personal Possessions for the Development of a Sense of Home of Nursing Home Residents

Personal possessions of nursing home residents can contribute to their sense of home. This study investigated which of the personal belongings were considered most important, and if these items indeed contributed to a sense of home. A qualitative research was conducted with 27 nursing home residents. Photographs, paintings, and pieces of furniture are objects with sentimental value. The television set is valued for its practical function. Residents of larger rooms have more flexibility in bringing along personal items, including pieces of furniture. The results of this study can be used for the design of nursing homes or for making informed choices during the process of institutionalization

Cyberspace, Blockchain, Governance:How Technology Implies Normative Power and Regulation

Technologies and their inherent design choices create normative structures that affect governance. This chapter aims to illustrate how blockchain technology in particular introduces new norms into a legal framework. We first analyze the different forms of governance by distinguishing between old and new governance. With a view to code that functions as legal norms, Blockchain technology is particularly suited to create governance structures and mechanisms. However, one needs to be aware of the norms that are implicitly introduced into the legal system by a specific blockchain technology. We look at the blockchain technology that underlies cryptocurrencies such as Bitcoin. This blockchain introduces a decentralized, transparent, cryptographically locked and thus immutable shared ledger. In summary, these design choices have normative powers over the user and over user interaction. If this is indeed the case, then regulators have to actively assess newly introduced digital ledger technology and other technologies for their effect on the normative and legal system.</p

Old Voters on New Dimensions:Why Do Voters Vote for Pensioners' Parties? The Case of the Netherlands

This article analyzes the electoral support of the Dutch pensioners’ party 50Plus. Due to its open electoral system and aging population, the Netherlands is a key case to study pensioners’ parties. Our study shows that this pensioners’ party appeals to voters who are characterized by their age and their dependence on the welfare state as well as their policy positions on new lines of political conflict. In particular, their position on the new economic dimension (which concerns welfare state reform) and the new cultural dimension (which concerns immigration and EU integration) is distinct. Moreover, even when the majority of voters for this new party once supported the larger mainstream parties, they are now dissatisfied with the established politics. With rapidly aging populations across established democracies, this study is not just relevant for those studying pensioners’ parties, but rather gives an important insight into the electoral dynamics and popular support for mainstream politics, the welfare state, and social security

Marine spatial planning: risk or opportunity for fisheries in the North Sea?

The North Sea is one of the busiest marine areas in the world. It is also a major fisheries ground. Bordered by seven countries with their own spatial uses and claims, the stage is set for complex and demanding governance challenges. Recent decades have also seen user groups multiply, competition for space and resources increase, and the pressure on the marine environment and its living natural resources grow. As governments strive to balance conservation and economic development needs, they also have to deal with inter-as well as intra-national user conflicts. Marine Spatial Planning (MSP) has arrived as a new approach to these issues. It is argued that for North Sea fishing people and their communities MSP holds risks as well as opportunities, depending on which institutions are formed and what role they are allowed to play in the planning process

Bridging the legitimacy gap—translating theory into practical signposts for legitimate flood risk governance

Legitimacy is widely regarded as a founding principle of ‘good’ and effective governance, yet despite intense academic debate and policy discourse, the concept remains conceptually confusing and poorly articulated in practice. To bridge this gap, this research performed an interpretive thematic analysis of academic scholarship across public administration, public policy, law, political science and geography. Three core themes were identified in relation to representative deliberation, procedural and distributive equity and justice, and socio-political acceptability, with numerous sub-themes therein. In an attempt to clarify conceptual confusion, this paper grounds these theoretical debates in the context of flood risk governance where numerous legitimacy dilemmas exist. A number of questions are presented as conceptual ‘sign posts’ to encourage reflexive governance in the future. Thus, more broadly, we assert the importance of bringing legitimacy to the forefront of contemporary flood risk governance discourse and practice, moving beyond the realm of academic reflection
