In non-clinical populations, facial features (eyes, nose, mouth) may vary in their contribution to face identity perception. Changes to whole faces are easier to detect than changes to individual features, and eye changes are typically easier to detect than mouth changes, which in turn are easier to detect than nose changes. However, how this differs for people with face recognition difficulties (developmental prosopagnosia; DP) and for individuals with superior face recognition abilities (super-recognisers; SR) is not clear; although findings from previous studies have suggested differences, the nature of this difference is not understood. The aim of this study was to examine whether differences in the ability to detect feature changes in DPs and SRs were (a) quantitative, meaning that the pattern across feature changes remained the same but there was an overall upwards or downwards shift in performance, or (b) qualitative, meaning that the pattern across feature changes was different. Using a change detection task in which individual face features (eyes, nose, mouth) changed between sequentially presented faces, we found that while prosopagnosics showed a quantitative difference in performance with a downwards shift across all conditions, super-recognisers only showed qualitative differences: they were better able to detect when the face was the same and were marginally (but not non-significantly) worse at detecting when the eyes changed. Further, the only condition which distinguished between the three groups was the ability to identify when the same face was presented, with SRs being better than controls, and controls being better than DPs. Our findings suggest that, in feature-matching tasks, differences for DPs are due to them being overall worse at the task, while SRs use a qualitatively different strategy. Full article

The hosts to gold around the Witwatersrand Basin span over 400 my, through 14 km of stratigraphy in a variety of host rocks and in tectonic settings that include periods of rifting, thermal subsidence, foreland basin, flood basalt outpouring, graben development, and further thermal subsidence. A geological model that assumes placer processes to explain this diversity implies a super-long-lived and special source of the detrital gold, transport, and highly effective sorting processes over a time span of 400 my. There is no evidence of a special source and sorting over such a long time period. In the Phanerozoic, this would be equivalent to the special source and sorting processes operating continually over an equivalent period of geological time spanning from the Devonian up until the present day; this is as yet recognised nowhere else on the planet. With regard to the geological model that assumes a placer process, this is untenable because of these scientific shortcomings and its lack of success in exploration. A better use of funds may be to consider alternative approaches and epigenetic models in exploration. Full article

Occupational health and safety (OHS) is a largely technical field, still guided by a biomedical model of health that seeks to isolate factors that cause injury. Despite a growing literature on organisational and managerial factors influencing occupational health, their full integration into the OHS concept has been slow. A broader understanding is still needed to recognise the restructuring of work and the link between well-being at work and management style. In the context of a rapidly changing world of work, increasing workforce diversity, and inequality, OHS needs to take account of the social sciences and humanities to broaden its reductionist vision. Occupational illnesses, distress, and suffering, especially in relation to relational or organisational issues, have no initial cause or specific ontology; they result from a long-standing process or repetitive relational pattern that needs to be exposed and understood in greater depth, considering contextual factors and dynamics. Using the authors’ anthropological backgrounds and the basic principles of the double bind theory developed many decades ago by Gregory Bateson and his colleagues at the Palo Alto School of Communication, we propose a reflection on pragmatic paradoxes or double bind situations in the workplace (which can be briefly defined as the presence of contradictory or conflicting demands or messages), their potential impact on workers’ health and well-being, and how to resolve them. This paper sought to explore the world of pragmatic paradoxes and double binds by discussing different categories, types, or forms of paradoxes/double binds that occur in the context of occupational health and their underlying mechanisms. It also includes a discussion of the possible link to the concept of super-diversity, as it too is associated with migration channels, employment, gendered flows, and local systems. Finally, we discuss the practical implications of this understanding for health professionals, researchers, and policymakers, from a perspective of promoting more holistic and context-sensitive interactional approaches to occupational health.

The early stages of orthodontic treatment are frequently associated with pain that can vary in intensity and duration, representing one of the main reasons for treatment discontinuation. Whilst the use of drugs is recognised as being effective to control orthodontic pain, there are no reliable data indicating the best first archwire for efficacy and minimum discomfort. A prospective controlled cohort study was conducted to compare the intensity and the characteristics of orthodontic pain during the first 15 days of treatment with 2 archwires. Fifty subjects were enrolled and divided into two groups: one received 0.012 inch stainless steel (SS) as the first archwire; the other, a 0.014 inch super-elastic nickel–titanium (Ni-Ti) archwire. Patients compiled a visual analogue scale to measure pain intensity over 15 days, a questionnaire for pain characteristics, the Somatosensory Amplification Scale and the State-Trait Anxiety Inventory to control the psychosocial component of pain. Dental casts were digitally analysed to evaluate the initial arch length discrepancy. In the first 3 days of treatment, the mean VAS values of the SS group were significantly lower than those of the Ni-Ti group (p < 0.05). No significant differences emerged between the groups concerning pain characteristics. The 0.012 inch SS archwire could be used at the beginning of orthodontic treatment to minimise pain perception and improve compliance. Full article

Using non-Indigenous perspectives of parental social and emotional wellbeing in the design and application of parent support programs can undermine program effectiveness as it may not account for Indigenous family structures and community values. With a clearer understanding of Indigenous parent wellbeing and its determinants, parenting interventions can be more appropriately designed and tailored to provide support for Indigenous families. This study utilised a community-based participatory action research approach involving collaboration between the research team, participants, and community advisory groups to explore Indigenous parents’ and carers’ conceptions of wellbeing. Participants’ cultural perspectives on parent wellbeing were collected through semi-structured focus groups and in-depth interviews (N = 20). Thematic analysis was undertaken using theory-driven and interpretative phenomenological analysis. Eleven themes emerged as risk and protective factors across three domains: child domain (i.e., school attendance and education, respect, routine, development), parent domain (i.e., role modelling, self-regulation of body, self-regulation of mind and emotions, parenting strategies), and context domain (i.e., connections to family and kinship, community, access to services). It is noteworthy that parents reported three super-ordinate intersecting themes across all domains: connection to culture, Country, and spirituality. In addition, Indigenous parents’ and carers’ conception of their own wellbeing is closely linked to their children’s wellbeing, their lived community context, and expected personal indicators. In recognising and working with this holistic view of Indigenous parent wellbeing, parent support programs can be optimally designed and implemented in Indigenous communities. Full article

There is currently little understanding of why some individuals find it difficult to engage in self-compassion (SC), defined as a form of self-kindness, self-acceptance, and courage to face one’s distress. This is especially true for women experiencing weight difficulties, despite the emergence of promising results from compassion-focused approaches to weight management. Consequently, this study undertakes a qualitative study to explore the experiences of barriers to self-compassion in women who were actively trying to manage their weight, using interpretative phenomenological analysis (IPA). A qualitative study was employed using an interpretive approach. Using purposive sampling, 10 women were recruited from London-based weight loss groups. Three super-ordinate themes emerged: (I) feeling unable to prioritise own needs over others’ needs; (II) having to learn and sustain a new approach to weight loss; and (III) having very high standards. The emergent themes suggest that women who face weight difficulties have numerous barriers to self-compassion. To fully utilise compassionate-based weight loss interventions for women, it is important to recognise these barriers and implement strategies to lessen their impact. Full article

The early-age cracking problem in concrete has long been recognised by civil engineers and scientists because it can jeopardise the intended serviceability of concrete structures. However, the effects of various crack control methods are different. This paper carried out field monitoring on a super-long wall with different crack control measures and compared the temperature and strain development process of the wall. In the middle of the super-long wall, the pipe cooling method reduced the hydration heat of concrete by 13 °C via a vertical pipe arrangement, but the wall could reach the maximum tensile strain earlier than with the other methods. By embedding an I-shaped steel plate in the induced joint method, a structurally stiff mutation zone was generated, and the maximum strain was generated at the induced seam web. By calculating and setting a reasonable construction length, the alternative bay construction method reduced the internal tensile strain of the structure. The early-age cracking of super-long mass concrete structures is affected more by restrained shrinkage than by temperature, so it is difficult to control early-age cracking by addressing only one factor.
