Deze voorlichtingspublicatie is bedoeld voor allen die te maken hebben of te maken krijgen met de selectie, toepassing en uitvoering van warmtebehandelingen. Daarbij moet gedacht worden aan constructeurs, lastechnici, werkvoorbereiders, enzovoorts. Deze voorlichtingspublicatie is een update van de bestaande NIL-voorlichtingspublicatie V990906 (september 1999) "Warmtebehandeling van metalen in relatie tot de lastechniek". De updating was noodzakelijk omdat er enerzijds geen document beschikbaar was met een duidelijk overzicht van de (belangrijkste) warmtebehandelingen en anderzijds omdat de ontwikkelingen in onder andere de nieuwe staalsoorten beperkingen (kunnen) stellen aan de uitvoering van warmtebehandelingen. De in deze voorlichtingspublicatie genoemde warmtebehandelingen zijn die, welke veel voorkomen in de staalverwerkende industrie en dus ook in de lastechniek. De meest belangrijke warmtebehandelingen worden in beknopte vorm behandeld. Doel van deze publicatie is voornamelijk basisinformatie te verschaffen over de warmtebehandelingen. Warmtebehandelingen hebben effecten op de metaalkundige aspecten, zoals de structuur en de daaraan gerelateerde mechanische eigenschappen. Daarom wordt in een aantal hoofdstukken aandacht besteed aan de opbouw (kristalstructuur) van de metalen, alsmede de invloed van het opwarmen naar en (snel) afkoelen vanaf een bepaalde warmtebehandelingstemperatuur. Daarnaast wordt ook beknopt ingegaan op de uitvoering van warmtebehandelingen. Het is echter geenszins de bedoeling met deze publicatie volledig te zijn.

Dagelijks worden zeer veel voorwerpen en constructies door middel van lassen gerepareerd. Of dit altijd juist gebeurt of dat de reparatie op de juiste wijze wordt aangepakt, is veelal de vraag. Vaak is er grote tijdsdruk en daardoor nauwelijks tijd de reparatie goed uit te voeren. Er zijn voorbeelden te over waar men, zonder nadenken, tot een reparatie is overgegaan en waarvan de reparatie nog eens moest worden overgedaan. Door, voordat tot de reparatie wordt overgegaan, na te denken over de materiaalidentificatie, de oorzaak van de storing of defect en daarop in te spelen, kan op voorhand vaak al tijd en geld bespaard worden. Deze voorlichtingspublicatie is niet direct bedoeld voor het repareren van lasfouten in lasverbindingen zelf, maar meer voor andere defecten die zijn opgetreden tijdens bedrijf van het onderdeel. Hierbij moet worden gedacht aan slijtage, corrosie of combinaties van beide. Doorgaans geldt voor de reparatie van lasfouten echter dezelfde systematische aanpak als in deze publicatie besproken. Uiteraard gelden in ieder geval dezelfde eisen als voor de oorspronkelijke las. Daarnaast kan deze publicatie ook als hulpmiddel worden gebruikt bij het ontwerpen van constructies. De constructeur weet doorgaans of de constructie wordt blootgesteld aan slijtage en/of corrosie. Door een juiste keuze van de toe te passen materialen kan de schade, veroorzaakt door deze fenomenen worden beperkt. Basiskennis van de aard van de optredende slijtage en/of corrosie is dan wel een voorwaarde. Vandaar dat in deze publicatie de meest voorkomende vormen van slijtage en corrosie beknopt worden besproken. Deze voorlichtingspublicatie is bedoeld voor allen die te maken hebben of te maken krijgen met de selectie, toepassing en reparatie van oppervlaktelagen. Daarbij moet gedacht worden aan constructeurs, lastechnici, werkvoorbereiders, enzovoorts. Deze voorlichtingspublicatie is een update van de bestaande Praktijkaanbeveling TCV05 - "Reparatie door lassen" (uitgave NIL d.d. september 1999). De updating was noodzakelijk, omdat er enerzijds geen document beschikbaar was met een duidelijk overzicht van de (belangrijkste) oppervlaktedefecten slijtage en corrosie en anderzijds, omdat de ontwikkelingen in onder andere de nieuwe oplaslegeringen en oplasprocessen beperkingen (kunnen) stellen aan de uitvoering ervan. De in deze voorlichtingspublicatie genoemde slijtage- en corrosiefenomenen zijn die, welke het meeste voorkomen in de industrie. Deze belangrijke fenomenen worden in beknopte vorm behandeld. Doel van deze publicatie is dan ook basisinformatie te verschaffen over deze fenomenen en hoe ze te bestrijden.

The conservation of our heritage buildings is a European wide policy objective. Historical buildings are not only works of art, but embody an important source of local identity and form a connection to our past. Protection agencies aim to preserve historical qualities for future generations. Their work is guided by restoration theory, a philosophy developed and codified in the course of the 19th and 20th century. European covenants, such as the Venice Charter, express shared views on the conservation and restoration of built heritage. Today, many users expect a building with modern comfort as well as a historical appearance. Moreover, new functionality is needed for building types that have outlived their original function. For example, how to reuse buildings such as old prisons, military barracks, factories, or railway stations? These new functions and new demands pose a challenge to restoration design and practices. Another, perhaps conflicting EU policy objective is the reduction of energy use in the built environment, in order to reach climate policy goals. Roughly 40% of the consumption of energy takes place in buildings, either in the production or consumption phase. However, energy efficiency is especially difficult to achieve in the case of historical buildings, because of strict regulations aimed at protecting historical values. Recently, there has been growing interest in energy efficient restoration practices in the Netherlands, as is shown by the 'energy-neutral' restoration of Villa Diederichs in Utrecht, the 'Boostencomplex' in Maastricht and De Tempel in The Hague. Although restoration of listed buildings is obviously focused on the preservation of historical values, with the pressing demands from EU climate policy the energy efficiency of historical building

Formative assessment (FA) is an effective educational approach for optimising student learning and is considered as a promising avenue for assessment within physical education (PE). Nevertheless, implementing FA is a complex and demanding task for in-service PE teachers who often lack formal training on this topic. To better support PE teachers in implementing FA into their practice, we need better insight into teachers’ experiences while designing and implementing formative strategies. However, knowledge on this topic is limited, especially within PE. Therefore, this study examined the experiences of 15 PE teachers who participated in an 18-month professional development programme. Teachers designed and implemented various formative activities within their PE lessons, while experiences were investigated through logbook entries and focus groups. Findings indicated various positive experiences, such as increased transparency in learning outcomes and success criteria for students as well as increased student involvement, but also revealed complexities, such as shifting teacher roles and insufficient feedback literacy among students. Overall, the findings of this study underscore the importance of a sustained, collaborative, and supported approach to implementing FA.

The concept of a working alliance is rooted in psychotherapy and has been studied extensively in that field. Much less research has been conducted into working alliances between chronic psychiatric patients and their case managers. The aim of this review was to identify what is known about the working alliance between chronic psychiatric patients and their case managers. An extensive survey of the literature produced 14 articles for this review. The results of studies conducted show that a good working alliance has positive effects on the functioning of patients, and that the quality of the alliance depends on both patient characteristics and the behaviour of the case managers. The results also indicate that the working alliance is largely determined in the first 3 months of the contact. Further research into the development of working alliances is necessary.

A loss of physical functioning (i.e., a low physical capacity and/or a low physical activity) is a common feature in patients with chronic obstructive pulmonary disease (COPD). To date, the primary care physiotherapy and specialized pulmonary rehabilitation are clearly underused, and limited to patients with a moderate to very severe degree of airflow limitation (GOLD stage 2 or higher). However, improved referral rates are a necessity to lower the burden for patients with COPD and for society. Therefore, a multidisciplinary group of healthcare professionals and scientists proposes a new model for referral of patients with COPD to the right type of exercise-based care, irrespective of the degree of airflow limitation. Indeed, disease instability (recent hospitalization, yes/no), the burden of disease (no/low, mild/moderate or high), physical capacity (low or preserved) and physical activity (low or preserved) need to be used to allocate patients to one of the six distinct patient profiles. Patients with profile 1 or 2 will not be referred for physiotherapy; patients with profiles 3–5 will be referred for primary care physiotherapy; and patients with profile 6 will be referred for screening for specialized pulmonary rehabilitation. The proposed Dutch model has the intention to get the right patient with COPD allocated to the right type of exercise-based care and at the right moment.

Study selection: Randomized controlled trials published after 2007 with (former) healthcare patients ≥ 21 years of age were included if physical activity was measured objectively using a wearable monitor for both feedback and outcome assessment. The main goal of included studies was promoting physical activity. Any concurrent strategies were related only to promoting physical activity. Data extraction: Effect sizes were calculated using a fixed-effects model with standardized mean difference. Information on study characteristics and interventions strategies were extracted from study descriptions. Data synthesis: Fourteen studies met the inclusion criteria (total n = 1,902), and 2 studies were excluded from meta-analysis. The overall effect size was in favour of the intervention groups (0.34, 95% CI 0.23–0.44, p < 0.01). Study characteristics and intervention strategies varied widely. Conclusion: Healthcare interventions using feedback on objectively monitored physical activity have a moderately positive effect on levels of physical activity. Further research is needed to determine which strategies are most effective to promote physical activity in healthcare programmes. Lay Abstract Wearable technology is progressively applied in health care and rehabilitation to provide objective insight into physical activity levels. In addition, feedback on physical activity levels delivered by wearable monitors might be beneficial for optimizing their physical activity. A systematic review and meta-analysis was conducted to evaluate the effectiveness of interventions using feedback on objectively measured physical activity in patient populations. Fourteen studies including 1902 patients were analyzed. Overall, the physical activity levels of the intervention groups receiving objective feedback on physical activity improved, compared to the control groups receiving no objective feedback. Mostly, a variety of other strategies were applied in the interventions next to wearable technology. Together with wearable technology, behavioral change strategies, such as goal-setting and action planning seem to be an important ingredient to promote physical activity in health care and rehabilitation.

Background: Around 13% of the world’s population suffers from obesity. More than 40% of people with obesity display emotional eating behaviour (eating in response to negative emotions or distress). It is an alternate to moreeffective coping strategies for negative emotions. Our study explored the opportunities for helping adults with emotional overeating using a virtual coach, aiming to identify preferences for tailored coaching strategies applicable in a personal virtual coach environment. Three different coaching strategies were tested: a validating, a focus-on-change, and a dialectical one – the latter being a synthesis of the first two strategies. Methods: A qualitative study used vignettes reflecting the two most relevant situations for people with emotional eating: 1. experiencing negative emotions, with ensuing food cravings; and 2. after losing control to emotional eating, with ensuing feelings of low self-esteem. Applied design: 2 situations × 3 coaching strategies. Participants: 71 adult women (Mage 44.4/years, range 19–70, SD = 12.86) with high scores on the DEBQ-emotional eating scale (Memo 3.65, range 1.69–4.92, SD = .69) with mean BMI 30.1 (range 18–46, SD = 6.53). They were recruited via dieticians’ practices, were randomly assigned to the conditions and asked how they would face and react to thepresented coaching strategies. Data were transcribed and a thematic analysis was conducted. Results: Qualitative results showed that participants valued both the validating coaching strategy and the focus-onchange strategy, but indicated that a combination of validation and focus-on-change provides both mental supportand practical advice. Data showed that participants differed in their level of awareness of the role that emotions play in their overeating and the need for emotion-regulation skills. Conclusion: The design of the virtual coach should be based on dialectical coaching strategies as preferred by participants with emotional eating behaviour. It should be tailored to the different stages of awareness of their emotions and individual emotion-regulation skills.
