The research in this dissertation explores the social significance of local memory websites. Local memory websites offer local residents a platform where they collect and share memories about particular places or experiences in their neighbourhoods and districts. Following a systematic review and a broad field study, a narrative approach is developed to study collective levels of empowerment within the ‘Memory of East’ and the ‘Memory of West’, both in Amsterdam. Two empirical questions steer a double case study: 1) ‘How does the organizational development influence the online dynamics?’ and 2) ‘What collective empowerment do the online dynamics express?’ With its stronger social capital, the Memory of East is more likely to resist official memory intuitions, commercial popular culture and local politics than the Memory of West. On the other hand, with its more inclusive character, the Memory of West is more representative for the broad cultural backgrounds of its inhabitants than the Memory of East. These findings are shown to be related to five organizational continuums on which both websites are plotted to indicate their crucial organizational differences. Apart from a claim about the theoretical value of this model, it is illustrated how it functions as a discursive tool for the core groups behind both websites.

Online platforms for collecting local memories are often claimed to be a driving force of empowerment for individuals, groups and the community as a whole. Long term online participation especially plays a key role in the claims for empowerment on group and community level. However, the present research on local memory websites lacks empirical data to substantiate these claims and leaves aside questions about their wider presence, the way they are organized and how their particular structure and affordances enable online participation. To address these issues, we develop six analytical dimensions in order to analyse a comprehensive number of such sites, examining in particular their organizational and online participatory features. On the basis of a cross-sectional design including 80 cases from the Netherlands, the United Kingdom and various other countries, we show three types of websites can be distinguished, namely residential, institutional and associational. In addition, we find that the expectancy of online participation is maximized not only by organizational aspects that fosterautonomy, but also by characteristics that enlarge the sense of authenticity. Our findings also show a limited number of cases with a considerable level of online participation, which offers the empirical data for analysis in terms of empowerment on group and community level.Nevertheless, we conclude that in most cases the organizational characteristics and participatory affordances of the websites are not sufficient to produce empowerment on all levels.

In this article, we explain how we envision the further interconnection of existing initiatives of online local memory collecting into a new social infrastructure, that is beneficial to the whole of Amsterdam. Three examples of local memory websites show how large districts in the East, South and West are represented thoroughly by local residents, in spite of differences in organizational characteristics. The concept of empowerment, as a multilevel construct, lends itself to frame these examples as important building blocks of socially sustainable districts and neighborhoods. Local knowledge, experiences and people become connected across Amsterdam when local memory websites become interconnected, by introducing city-wide compelling themes. Discussing this social infrastructure in relation to the concept of smart cities, leads us to a plea for more research focus on sociably smart cities.

Memory forms the input for future behavior. Therefore, how individuals remember a certain experience may be just as important as the experience itself. The peak-and-end-rule (PE-rule) postulates that remembered experiences are best predicted by the peak emotional valence and the emotional valence at the end of an experience in the here and now. The PE-rule, however, has mostly been assessed in experimental paradigms that induce relatively simple, one-dimensional experiences (e.g. experienced pain in a clinical setting). This hampers generalizations of the PE-rule to the experiences in everyday life. This paper evaluates the generalizability of the PE-rule to more complex and heterogeneous experiences by examining the PE-rule in a virtual reality (VR) experience, as VR combines improved ecological validity with rigorous experimental control. Findings indicate that for more complex and heterogeneous experiences, peak and end emotional valence are inferior to other measures (such as averaged valence and arousal ratings over the entire experiential episode) in predicting remembered experience. These findings suggest that the PE-rule cannot be generalized to ecologically more valid experiential episodes.

This paper puts forward a conceptual proposition that ties the discourses on ‘urban memory’ (Stillman and Johanson, 2009; Ringas, Christopoulou, Stefanidakis., 2011; Loughran, Fine & Hunter, 2015), sensory ethnography (Pink 2017 ), and counter-mapping (Crampton and Krygier 2018; ) with digital methods (Rogers, Sánchez-Querubín, and Kil, 2015). As an ‘interventionist’ approach, we understand co-producing counter (dynamic) maps with local stakeholders (actors), coupled with sensory and sentient data as a way of capturing the memory of urban peripheral landscapes (through intervention and participation) and thus creating archival knowledge.Urban memory is often understood as a form of collective memory that isconstituted by individual experiences within the place itself and through its historyand social environment (Ringas et al., 2011). With rapid changes in digitaltechnologies, digital and material have become “inseparate and entangled inenvironments people move and navigate their lives through'' (Pink and Fors, 2017).Memories are “evoked with material engagement with devices” which “opens up afield of sensory and affective engagement” research (ibid). While Pink and Forspropose to follow such engagement in a mundane and everyday setting, seen as anon-representational, phenomenological approach, we put forward a mixedmethods approach that connects sensory and sentient data (as agents) with the largerenvironmental context.Urban areas are often conceptualized as sites of ‘creative destruction’, in between stability and change, space (that can be developed) and place (that is lived in), often subjected to planning, regulation, and economic forces (Batty, 2007). This is especially true for urban areas that are located outside of the ‘center’ or in the cities’ periphery. These areas have experienced an endless cycle of deconstruction and reconstruction often witnessed and captured by local inhabitants, creatives, and activists. Currently, many of the peripheral areas are emancipating, bringing forward and openly communicating their complexities, values, and engaging various stakeholders in their regeneration efforts (which happens in a broader context of many European cities repositioning themselves in more polycentric and polyphonic ways, (Scott, 2015).To be able to capture the memory of ever-changing, ‘built a new’ urban places, we put forward counter (dynamic) mapping using digital methods as complemented with sensory and sentient data generated through interactions with digital technologies. Building on Crampton’s notion of maps (Crampton and Krygier, 2018), cartography is understood as existence (becoming) rather than essence (fixed ontology). Maps are therefore taken not as ‘objects’, but as performative practices. Digital methods, on the other hand, enable us to understand dynamic place-making, through ‘tracing’ the stakeholders (actors) and their relations overtime to capture the ways the urban environment gets performed.To clarify with an example, in Spinoza Imaginaries Lab & Cafe situated inAmsterdam Southeast we have been capturing the ever changing urbanenvironment in partnership with local stakeholders (actors), mapping their evolvingrelationships (and grouping) using the IssueCrawler and sentient data co-gatheredby researchers and students, with the clear understanding that to be able to capturea place, it is important to map the vernacular knowledge of that place (imaginaries,including art, movies, unrealized plans and initiatives, etc.). We propose this mixedmethods approach as an epistemological practice geared towards archiving thedynamic state of urban peripheral landscapes.

The exploration of the narrative nature of local memory websites in relation to empowerment theory produces new insights in the nested levels of analysis of both. Empowerment’s value orientation calls for a focus on strengths instead of weaknesses and, as such, requires specific language that accommodates the conviction that resources are locally available, instead of scarce. Consequently, empowerment theory describes resources as being present in processes and outcomes on interdependent psychological, organizational and communal levels. The application of the empowerment framework’s components to the theoretical outcomes and processes of local memory websites illuminates the connecting roles local narratives play as resources in empowerment. First of all, personal stories, community narratives and dominant cultural narratives influence and support each other across levels. Secondly, narratives spread local knowledge which leads to shared values and common believes for collectives on various levels. And thirdly, the sharing of narratives happens through social networks that manifest themselves on different levels, which, as such, facilitate sharing other resources. Based on these perspectives, we offer a simplified model for empowerment with a focus on the interdependencies between levels of networks. Against this background, we discuss relevant analytical perspectives as a departure point for the empirical exploration of unstudied relations between empowerment and local memory websites.

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

Background: The Nurses in the Lead (NitL) programme consists of a systematic approach and training to 1) empower community nurses in implementing evidence, targeted at encouraging functional activities of older adults, and 2) train community nurses in enabling team members to change their practice. This article aims to describe the process evaluation of NitL. Methods: A mixed-methods formative process evaluation with a predominantly qualitative approach was conducted. Qualitative data were collected by interviews with community nurses (n = 7), focus groups with team members (n = 31), and reviewing seven implementation plans and 28 patient records. Quantitative data were collected among community nurses and team members (N = 90) using a questionnaire to assess barriers in encouraging functional activities and attendance lists. Data analysis was carried out through descriptive statistics and content analysis. Results: NitL was largely executed according to plan. Points of attention were the use and value of the background theory within the training, completion of implementation plans, and reporting in patient records by community nurses. Inhibiting factors for showing leadership and encouraging functional activities were a lack of time and a high complexity of care; facilitating factors were structure and clear communication within teams. Nurses considered the systematic approach useful and the training educational for their role. Most team members considered NitL practical and were satisfied with the coaching provided by community nurses. To optimise NitL, community nurses recommended providing the training first and extending the training. The team members recommended continuing clinical lessons, which were an implementation strategy from the community nurses. Conclusions: NitL was largely executed as planned, and appears worthy of further application in community care practice. However, adaptations are recommended to make NitL more promising in practice in empowering community nurse leadership in implementing evidence.

In this article we study the evolvement of empowering and dis-empowering aspects of a local memory website, initiated by the Amsterdam Museum and currently active for more than a decade. The results partly fill a gap in the available literature about this field, because the relation between collective empowerment and online behaviour in these communities has been underexposed. Departing from a narrative perspective on memories as resources for empowerment, we show how the online dynamics around these memories exhibit collective processes of identity formation, social learning and networking. However, certain patterns in the online dynamics also uncover that, although the online activity is increasing, the diversity in the content and the number of participants are decreasing. Describing the organizational development of the local memory community, we argue that the growth into a self-organizing community is the cause of increasing activity and decreasing participation. This implies that the online community has become a small, empowered group, which at the same time has developed dis-empowering characteristics, i.e. limitations to include ‘other’ locals, neighbourhoods and topics. We illustrate how the current self-organization, unintentionally, fuels the decreasing diversity in content by a natural selection process of a rather homogeneous group of participants. In addition, the conviction of what constitutes a successful online community is discussed for emphasizing individual empowerment and attracting empowered locals instead of vulnerable ones.

Menschen mit einer psychotischen Störung haben häufig ein negatives Selbstbild und damit ein geringes Selbstwertgefühl. Untersuchungen haben auch gezeigt, dass Paranoia direkt mit negativen Vorstellungen über das Selbst zusammenhängen kann. Sich minderwertig zu fühlen und an Paranoia zu leiden, kann zu Verletzlichkeit und Aggression führen. In der forensischen Psychiatrie gibt es eine Kategorie stationärer Patienten mit einer psychotischen Erkrankung und Paranoia. Diese Patienten leiden schwer unter ihrer Störung, die obendrein ein Prädiktor für einen ungünstigen Behandlungsverlauf ist und eine lange Verweildauer innerhalb der (forensischen) Psychiatrie nach sich zieht. In einer randomisierten kontrollierten Studie wird die Wirksamkeit des Competitive Memory Training (COMET), eines kognitiv-verhaltenstherapeutischen Behandlungsprogramms zur Verbesserung des Selbstbildes bei in der Forensik untergebrachten psychotischen Patienten, die ebenfalls an Paranoia leiden, evaluiert und untersucht, ob ein positiveres Selbstbild auch zur Verringerung der Paranoia dieser Patienten führt. Die an einer kleinen Stichprobe durchgeführte Studie ergab eine signifikante Verbesserung des Selbstwertgefühls, aber keine Verringerung der Paranoia bei den Patienten, die an COMET teilnahmen.
