Masonry structures comprise a significant portion of the historical building stock all over the world. Previousstudies have clearly pointed out that unreinforced masonry buildings are vulnerable against extreme loadingconditions, such as seismic actions. Therefore, strengthening is inevitable in most cases for historical masonry towithstand severe loads. In this paper, the efficiency of fabric reinforced cementitious matrix is investigatedexperimentally by using diagonal tension tests. Fourteen wallets with a nominal size of 750x750x235 mm wereproduced with using solid clay bricks and a low-strength mortar. The bricks were collected from the structuralwalls of an early-20th century building under restoration. The low-strength mortar represents the historicalmortar commonly used in similar historical brick masonry buildings located in Istanbul, Turkey. By testing thespecimens under monotonic diagonal compression loads, the effects of different types of plasters on the walletsurface, varying types of fibers used in textile reinforcement and anchors used for the connection between FRCMand substrate are investigated. Although the wallet samples have inherent shortcomings in representing overallcomponent response accurately, still the qualitative findings are enlightening the effectiveness of the FRCMsystem by increasing shear strength, stiffness (shear modulus) and dissipated energy of the masonry wallets. Thestrengthened specimens were failed due to shear sliding along a bed joint and/or by a stair-shaped separationwhile the refence specimens were failed due to the splitting of the specimen into two parts in the stair-steppedshape and a slipping through a bed joint.

Coupling beams between shear walls are one of the key elements for energy dissipation in tall buildings. A representative mathematical model of coupling beam should represent flexure, shear and interface slip/extension mechanisms simultaneously. This goal can be achieved by using either detailed finite element models or by using macro models. This paper presents a review of various macro model alternatives for diagonally reinforced coupling beams in the literature. Three distinct methods have been reviewed in terms of their modeling techniques, the cyclic response overlap and the amount of cumulative plastic energy dissipated based on the results of previously performed tests. Through an analytical study, adequately accurate results can be captured by using macro models, although they are simpler in practice compared to sophisticated micro models. This study shows that, by modifying ultimate shear capacities where concrete material between diagonal bundles is adequately confined, it is possible to capture a more realistic result and a better approximation to the actual responses. It is also concluded that a simpler numerical model for diagonally reinforced coupling beams can be achieved by introducing linear part of slip/extension behavior into elastic part of the beam. It is observed, as a result of this study, that the ratio of effective stiffness to that of the gross cross-sectional one ranges from 0.04 to 0.14 in diagonally reinforced coupling beams depending on the aspect ratio and the beam strength parameters.

Abstract Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently flled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fts-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efcacy of AR and VR training tools.

In clinical practice, formal elements of art products are regularly used in art therapy observation to obtain insight into clients’ mental health and provide directions for further treatment. Due to the diversity of formal elements used in existing studies and the inconsistency in the interpretation, it is unclear which formal elements contribute to insight into clients’ mental health. In this qualitative study using Constructivist Grounded Theory, eight art therapists were interviewed in-depth to identify which formal elements they observe, how they describe mental health and how they associate formal elements with mental health. Findings of this study show that art therapists in this study observe the combination of movement, dynamic, contour and repetition (i.e., primary formal elements) with mixture of color, figuration and color saturation (i.e., secondary formal elements). Primary and secondary elements interacting together construct the structure and variation of the art product. Art therapists rarely interpret these formal elements in terms of symptoms or diagnosis. Instead, they use concepts such as balance and adaptability (i.e., self-management, openness, flexibility, and creativity). They associate balance, specifically being out of balance, with the severity of the clients’ problem and adaptability with clients’ strengths and resources. In the conclusion of the article we discuss the findings’ implications for practice and further research.

Property sharing is one of the most prominent examples of the rapidly expanding sharing economy. Travelers around the world often opt to stay at a stranger's apartment instead of any other tourism accommodation. Trust is essential in this choice, because staying with, or taking in, strangers can entail great risks. To create trust between users, sharing platforms often promote a sense of community. However, the relation between sense of community and trust in the sharing economy is still largely unknown. To investigate this relation, both hosts and guests of two sharing platforms, namely Airbnb and SabbaticalHomes, were surveyed. The findings indicate that sense of community indeed enhances trust between users. Moreover, the evidence suggests that hosts have a stronger sense of community than guests. Also, a significantly higher sense of community was found on the platform where identification between users is higher. This study shows that affect for the community contributes to the understanding of trust in the sharing economy.

This paper aims to offer a critical reflection on the way Talent Management (TM) is investigated in practice, by addressing the key issues regarding the quality (in terms of rigor and relevance) of academic empirical TM research and therefore the critical scrutiny of TM scholars’ work. We will argue that despite the growth in the quantity, the quality of many empirical TM papers is lagging behind and hindering the progress of the academic field of TM.

Eindrapportage fase 1- Ontwerpfase. Er is een sterk gedeeld gevoel dat wijkcultuurhuizen belangrijk zijn voor de stad Utrecht. Utrecht biedt met de wijkcultuurhuizen een unieke infrastructuur om cultuurparticipatie van Utrechters te bevorderen. De wijkcultuurhuizen – Cultuur 19, De Vrijstaat, Het Wilde Westen, Jongeren Cultuurhuis Kanaleneiland en ZIMIHC – zijn laagdrempelige culturele voorzieningen die creativiteit in de samenleving stimuleren en bijdragen aan de sociale basis. De sociale basis wordt ook wel aangeduid als het ‘cement’ in de samenleving, een weefsel van verbindingen. Bij de sociale basisinfrastructuur gaat het, naast de bestaande infrastructuur van het sociale domein, om de aanwezigheid van informele netwerken, burgeractiviteiten en betekenisvolle relaties tussen burgers onderling en tussen burgers, professionals en de overheid (Van Pelt, Repetur & Van Yperen, 2018). Vanuit de gemeente Utrecht wordt het belang van wijkcultuurhuizen benadrukt. Het credo is cultuurparticipatie: ‘Cultuur voor iedereen’. Wijkcultuurhuizen bevorderen cultuurparticipatie door onder andere het faciliteren van amateurkunst, het initiëren van kunst- en cultuureducatie, het aanbieden van kunstzinnige cursussen en het mogelijk maken van sociaalartistieke projecten. Gemeente Utrecht heeft het lectoraat Participatie en Stedelijke Ontwikkeling (PSO) gevraagd onderzoek te doen vanuit de volgende behoefte: 1. een brede probleeminventarisatie en -analyse als basis voor verder beleid rond de wijkcultuurhuizen in de nieuwe coalitieperiode 2018-2022; 2. het verder onderzoeksmatig bijdragen aan de doorontwikkeling van lopende projecten en activiteiten van de wijkcultuurhuizen in de praktijk (zoals bijvoorbeeld het project De Kunst van Delen waar in 2018 onderzoek naar is gedaan (Van der Maas, Hamers, Bouma & De Vos, 2018). In 2019 is gestart met de eerste fase van het uitgebreidere onderzoek, de ontwerpfase. Deze eerste fase bestaat uit een onderzoek naar de beleidskaders en gaat op zoek naar ontwerpdimensies en bijpassende gemeentelijke en organisatorische beleidsmatige kaders voor wijkcultuurhuizen om cultuurparticipatie succesvol te bevorderen

Formal elements are often used in art therapy assessment. The assumption is that formal elements are observable aspects of the art product that allow reliable and valid assessment of clients’ mental health. Most of the existing art therapy assessment instruments are based on clinical expertise. Therefore, it is not clear to what degree these instruments are restricted to formal elements. Other aspects might also be included, such as clinical expertise of the therapist. This raises the question of whether and how formal elements as observable aspects of the art product are related to clients’ mental health. To answer this question, four studies are presented that look at: (1) a meta-theoretical description of formal elements; (2) operationalization of these formal elements so they can be analyzed reliably in clients’ art products; (3) establishment of reliable and clinically relevant formal elements; (4) the relationship between formal elements and adult clients’ mental health. Results show that the combination of the formal elements “movement,” “dynamic,” and “contour” are significantly interrelated and related to clients’ mental health, i.e., psychopathology, psychological flexibility, experiential avoidance, and adaptability. These findings give insight in the diagnostic value of art products and how they may add to clients’ verbal expression and indicate their potential to benefit from therapy.

Dynamic body feedback is used in dance movement therapy (DMT), with the aim to facilitate emotional expression and a change of emotional state through movement and dance for individuals with psychosocial or psychiatric complaints. It has been demonstrated that moving in a specific way can evoke and regulate related emotions. The current study aimed to investigate the effects of executing a unique set of kinetic movement elements on an individual mover’s experience of happiness. A specific sequence consisting of movement elements that recent studies have related to the feeling of happiness was created and used in a series of conditions. To achieve a more realistic reflection of DMT practice, the study incorporated the interpersonal dimension between the dance movement therapist (DMTh) and the client, and the impact of this interbodily feedback on the emotional state of the client. This quantitative study was conducted in a within-subject design. Five male and 20 female participants (mean age = 20.72) participated in three conditions: a solo executed movement sequence, a movement sequence executed with a DMTh who attuned and mirrored the movements, and a solo executed movement sequence not associated with feelings of happiness. Participants were only informed about the movements and not the feelings that may be provoked by these movements. The effects on individuals were measured using the Positive and Negative Affect Schedule and visual analog scales. Results showed that a specific movement sequence based on movement elements associated with happiness executed with a DMTh can significantly enhance the corresponding affective state. An additional finding of this study indicated that facilitating expressed emotion through movement elements that are not associated with happiness can enhance feelings such as empowerment, pride, and determination, which are experienced as part of positive affect. The results show the impact of specific fullbody movement elements on the emotional state and the support outcome of DMT on emotion regulation.
