Tracking physical resources at the construction site can generate information to support effective decision-making and building production control. However, the methods for conventional tracking usually offer low reliability. This study aims to propose the integrated Smart Twins 4.0 to track and manage metallic formworks used in cast-in-place concrete wall systems using internet of things (IoT) (operationalized by radio frequency identification [RFID]) and building information modeling (BIM), focusing on increasing quality and productivity.

Design science research is the research approach, including an exploratory study to map the constructive system, the integrated system development, an on-site pilot implementation in a residential project and a performance evaluation based on acquired data and the perception of the project’s production team.

In all rounds of requests, Smart Twins 4.0 registered and presented the status from the formworks and the work progress of buildings in complete correspondence with the physical progress providing information to support decision-making during operation. Moreover, analyses of the system infrastructure and implementation details can drive researchers regarding future IoT and BIM implementation in real construction sites.

The primary contribution is the system proposal, centralized into a mobile app that contains a Web-based virtual model to receive data in real time during construction phases and solve a real problem. The paper describes Smart Twins 4.0 development and its requirements for tracking physical resources considering theoretical and practical previous research regarding RFID, IoT and BIM.

Unwanted intrusive thoughts (UITs) are a major public health concern (Nock et al., 2008; Bentum et al., 2017), and they are key to the development of a variety of dysregulated behaviours (Jungmann et al., 2016; Bergen et al., 2012). Thus, this study aims to investigate reductive mechanisms for unwanted intrusive thoughts by analysing aspects of affectivity in clinical and non-clinical samples.

Quantitative means of data collection and analysis were used to explore UITs and affectivity. In total, 530 adults took part in this study (236 males, 253 females and 15 transgenders). Participants consisted of clinical (N = 168) and non-clinical samples (N = 336) who completed the Midlife in the United States sense of control scale (Lachman and Weaver, 1998), 20-item neuroticism scale (Goldberg, 1999), self-compassion scale (Neff, 2003a), flourishing scale (Diener et al., 2009), Positive and Negative Affect Schedule - Negative Scale (Watson et al., 1988), generalised anxiety disorder seven-item (Spitzer et al., 2006) and repetitive thinking questionnaire-10 (McEvoy et al., 2010).

Participants who experienced high levels of psychological flourishing, emotional stability, self-compassion, perceived control and affective well-being were prone to experience minimal UITs. Anxiety was positively related to UITs. These findings suggest that these aspects of affectivity may aid the reduction or management of clinical and non-clinical unwanted intrusive thoughts.

This study has addressed gaps in knowledge and the literature on UITs by demonstrating that psychological flourishing, emotional stability, self-compassion, perceived control and affective well-being as aspects of affectivity can be implemented as a reductive mechanism for UITs, and such implementation may have a high probability of effective reduction or management of clinical and non-clinical unwanted intrusive thoughts.
