Valuation judgement bias has been a research topic for several years due to its proclaimed effect on valuation accuracy. However, little is known on the emphasis of literature on judgement bias, with regard to, for instance, research methodologies, research context and robustness of research evidence. A synthesis of available research will establish consistency in the current knowledge base on valuer judgement, identify future research opportunities and support decision-making policy by educational and regulatory stakeholders how to cope with judgement bias. This article therefore, provides a systematic review of empirical research on real estate valuer judgement over the last 30 years. Based on a number of inclusion and exclusion criteria, we have systematically analysed 32 relevant papers on valuation judgement bias. Although we find some consistency in evidence, we also find the underlying research to be biased; the methodology adopted is dominated by a quantitative approach; research context is skewed by timing and origination; and research evidence seems fragmented and needs replication. In order to obtain a deeper understanding of valuation judgement processes and thus extend the current knowledge base, we advocate more use of qualitative research methods and scholars to adopt an interpretative paradigm when studying judgement behaviour.

This thesis provides an examination of judgement autonomy of Dutch commercial real estate valuers in relation to client orientation. The valuation of commercial real estate such as offices or retail properties requires in-depth analysis due to its uniqueness by location, building type and usage details. Essentially, a register-valuer is qualified and instructed to assess a property value to one’s best cognitive effort and inform others of this outcome by means of a valuation report. In the Netherlands, concerns over independence risks and client-related judgement risks of valuers have been raised by regulative authorities as the Dutch Central Bank (DNB) and the Dutch Authority for the Financial Markets (AFM). A significant part of these concerns followed the 2008 financial crisis, which appeared to be at least partially driven by unreliable and incomparable valuations of Dutch commercial real estate (AFM, 2014; DNB, 2012; 2015). Among other things, these concerns led to the instigation of the Nederlands Register Vastgoed Taxateurs (NRVT) in 2015. NRVT is a new Dutch central register of valuation practitioners set up in order to improve self-regulation, quality control and compliance of valuation practitioners. Currently, the chamber for commercial real estate valuation holds about 2,000 commercial valuation registrations (NRVT, 2020). The introduction of NRVT, and other measures taken, reflect an instrumental view towards enhancing professionalism of Dutch valuers. This view is based on a systematic orientation to professional conduct in which good practice is primarily objectively determined (Van Ewijk, 2019). However, Wassink and Bakker (2016) point out that individuals make personal choices in order to deal with work complexity. Insight into and reflection on individual choices is part of what is referred to as normative aspects of professionalisation: what norms prevail in individual judgement and decision-making and why (Van Ewijk, 2019). In this regard, insight into judgement reasoning of valuation practitioners may contribute to normative levels of professional development of valuers. The need for such is expressed through community concerns over how individual judgement autonomy may become subdued due to instrumental-driven developments taking place in the sector. The combination of authoritative concerns over professional quality in the Netherlands and lack of (scientific) insight on how client influence affects judgement in valuation practice poses a problem: How may practitioners address client-related judgement bias risks and improve valuation accuracy from this viewpoint, if little is known on how such risks may occur in daily practice? The seemingly scarce scientific insights available in this regard in the Netherlands may also prevent educational programs to adequately address valuer independence and objectivity risks in relevant training programs. In order to address this knowledge gap, the present PhD research examines the following research problem: 169 Summary “How does client orientation affect professional judgement autonomy of commercial real estate valuers in the Netherlands?” The term ‘client orientation’ should be broadly interpreted and may refer to valuers’ perception, understanding and meaning given to alleged, actual or anticipated client-related aspects. Information on such client aspects is not required for the performance of valuation instructions. It should also be noted that this research examines the context of how client orientation may affect valuer judgement reasoning patterns during work practice, yet not its effect in terms of decision on final value opinion.

Purpose – Information verification is an important factor in commercial valuation practice.Valuers use their professional autonomy to decide on the level of verification required, thereby creating an opportunity for client-related judgement bias in valuation. The purpose of this paper is to assess the manifestation of client attachment risks in information verification. Design/methodology/approach – A case-based questionnaire was used to retrieve data from 290 commercial valuation professionals in the Netherlands, providing a 15 per cent response rate of the Dutch commercial valuation population. Descriptive and inferential statistics have been used to test research hypotheses involving relations between information verification and professional features that may indicate client attachment such as an executive job level and brokerage experience. Findings – The results reveal that valuers acting at partner level within their organisation obtain lower scores on information verification compared to lower-ranked valuers. Also, brokerage experience correlates negatively to information verification of valuation professionals. Both findings have statistical significance. Research limitations/implications – The results reflect valuers’ reasoning behaviour rather than actual behaviour. Replication of findings through experimental design will contribute to research validity. Practical implications – Maintaining close client contact in a competitive environment is important for business continuity yet may foster client attachment.The associated downside risks in valuation practice call for higher awareness of (subconscious) client influence and the development of attitudinal scepticism in valuer training programmes. Originality/value – This paper is one of the few that explore possible sources of valuer judgement bias by relating client-friendly valuer features to a key area of valuation i.e. information verification.

In this paper, we report on the initial results of an explorative study that aims to investigate the occurrence of cognitive biases when designers use generative AI in the ideation phase of a creative design process. When observing current AI models utilised as creative design tools, potential negative impacts on creativity can be identified, namely deepening already existing cognitive biases but also introducing new ones that might not have been present before. Within our study, we analysed the emergence of several cognitive biases and the possible appearance of a negative synergy when designers use generative AI tools in a creative ideation process. Additionally, we identified a new potential bias that emerges from interacting with AI tools, namely prompt bias.

This paper is a summary paper of the Thematic Working Group (TWG) on Adult Mathematics Education (AME). As the only thematic working group that focuses on adults’ lived experiences of mathematics, the research makes an important contribution to the field of Mathematics Education. The main themes in this group identify that adult numerical behaviour goes beyond the mathematics skills, knowledge, and procedures taught in formal education It is multifaceted, requiring the use of higher order skills of analysis and judgement, applied within a broad array of life’s contexts, experienced through a range of emotions. The research in this group points to the need to raise the profile of research that shows the benefits to adults of learning mathematics but also the long term economic disbenefits in the neglect of teaching and teacher training for this group.

A model for programmatic assessment in action is proposed that optimizes assessment for learning as well as decision making on learner progress. It is based on a set of assessment principles that are interpreted from empirical research. The model specifies cycles of training, assessment and learner support activities that are completed by intermediate and final moments of evaluation on aggregated data-points. Essential is that individual data-points are maximized for their learning and feedback value, whereas high stake decisions are based on the aggregation of many data-points. Expert judgment plays an important role in the program. Fundamental is the notion of sampling and bias reduction for dealing with subjectivity. Bias reduction is sought in procedural assessment strategies that are derived from qualitative research criteria. A number of challenges and opportunities are discussed around the proposed model. One of the virtues would be to move beyond the dominating psychometric discourse around individual instruments towards a systems approach of assessment design based on empirically grounded theory.

Abstract Background One of the most problematic expression of ageing is frailty, and an approach based on its early identification is mandatory. The Sunfrail-tool (ST), a 9-item questionnaire, is a promising instrument for screening frailty. Aims • To assess the diagnostic accuracy and the construct validity between the ST and a Comprehensive Geriatric Assessment (CGA), composed by six tests representative of the bio-psycho-social model of frailty; • To verify the discriminating power of five key-questions of the ST; • To investigate the role of the ST in a clinical-pathway of falls’ prevention. Methods In this retrospective study, we enrolled 235 patients from the Frailty-Multimorbidity Lab of the University-Hospital of Parma. The STs’ answers were obtained from the patient’s clinical information. A patient was considered frail if at least one of the CGAs’ tests resulted positive. Results The ST was associated with the CGA’s judgement with an Area Under the Curve of 0.691 (CI 95%: 0.591–0.791). Each CGA’s test was associated with the ST total score. The five key-question showed a potential discriminating power in the CGA’s tests of the corresponding domains. The fall-related question of the ST was significantly associated with the Short Physical Performance Battery total score (OR: 0.839, CI 95%: 0.766–0.918), a proxy of the risk of falling. Discussion The results suggest that the ST can capture the complexity of frailty. The ST showed a good discriminating power, and it can guide a second-level assessment to key frailty domains and/or clinical pathways. Conclusions The ST is a valid and easy-to-use instrument for the screening of frailty.

Discussiepaper over klanthechting en informatieverificatie in taxeren. Dit artikel gaat in op de relatie tussen hechting aan de klant enerzijds en de controle van klantgerelateerde informatie anderzijds. Klanthechting (Engels: client attachment), is een relevant thema in sectoren waarin oordeelsvorming en klantbelangen centraal staan. Het is immers niet ondenkbaar dat dienstverleners zich minder kritisch opstellen bij (belangrijke) klanten vanuit het oogpunt van klant- en omzetbehoud. In de volgende paragraaf is literatuur verkend over mogelijke risico’s bij onderzoeksinspanning in professionele dienstverlening. Vervolgens is in een enquête onder registertaxateurs in Nederland het effect van twee potentiële risicofactoren op de kwaliteit van informatiecontrole onderzocht. De bevindingen zijn aan het eind van dit artikel verwoord.

Background: Geriatric rehabilitation positively influences health outcomes in older adults after acute events. Integrating mobile health (mHealth) technologies with geriatric rehabilitation may further improve outcomes by increasing therapy time and independence, potentially enhancing functional recovery. Previous reviews have highlighted positive outcomes but also the need for further investigation of populations receiving geriatric rehabilitation. Objective: Our main objective was to assess the effects of mHealth applications on the health status of older adults after acute events. A secondary objective was to examine the structure and process elements reported in these studies. Methods: Systematic review, including studies from 2010 to January 2024. Studies were eligible if they involved older adults’ post-acute care and used mHealth interventions, measured health outcomes and compared intervention and control groups. The adjusted Donabedian Structure-Process-Outcome (SPO) framework was used to present reported intervention processes and structures. Results: After initial and secondary screenings of the literature, a total of nine studies reporting 26 health outcomes were included. mHealth interventions ranged from mobile apps to wearables to web platforms. While most outcomes showed improvement in both the intervention and control groups, a majority favored the intervention groups. Reporting of integration into daily practice was minimal. Conclusion: While mHealth shows positive effects on health status in geriatric rehabilitation, the variability in outcomes and methodologies among studies, along with a generally high risk of bias, suggest cautious interpretation. Standardized measurement approaches and co-created interventions are needed to enhance successful uptake into blended care and keep geriatric rehabilitation accessible and affordable.

The aim of this systematic review was to examine the association between malnutrition and oral health in older people (≥ 60 years of age). A comprehensive systematic literature search was performed in four databases (PubMed, CINAHL, Dentistry and Oral Sciences Source, and Embase) for literature from January 2000 to May 2020. Both observational and intervention studies were screened for eligibility. Two reviewers independently screened the search results to identify potential eligible studies, and assessed the methodological quality of the full-text studies. A total of 3240 potential studies were identified. After judgement for relevance, 10 studies (cross-sectional (n = 9), prospective cohort (n = 1)) met the inclusion criteria. Three studies described malnourished participants as having fewer teeth, or functional (tooth) units (FTUs), compared to well-nourished participants. Four studies reported soft tissue problems in malnourished participants, including red tongue with blisters, and dry or cracked lips. Subjective oral health was the topic in six studies, with poorer oral health and negative self-perception of oral health in malnourished elderly participants. There are associations between (at risk of) malnutrition and oral health in older people, categorized in hard and soft tissue conditions of the mouth, and subjective oral health. Future research should be focused on longitudinal cohort studies with proper determination of malnutrition and oral health assessments, in order to evaluate the actual association between malnutrition and oral health in older people.
