What is body neutrality and how is it different to existing body image concepts? An analysis of experts and general community responses

There has been considerable recent interest in and reference to body neutrality, despite limited scholarship on differences from existing constructs. Our study examined perceptions of body neutrality in 229 individuals (researchers, clinicians, eating disorder lived experience, general community). Questions explored definitions of body neutrality, its similarity and differences to other concepts, perceived benefits and risks of adopting a body neutrality approach, and ratings on the usefulness of proposed components. Participants defined body neutrality as adopting an accepting, non-judgemental approach to one’s body, de-emphasising the importance of appearance, and viewing the body as a vessel that carries a person through life. Perceived benefits included it being more accessible than existing approaches and a useful coping strategy, while risks were that neutrality can be difficult to adopt in an appearance focused society and that it may prompt an apathetic response to self-care. Body neutrality was rated as conceptually similar to functionality appreciation, body acceptance, and body compassion, and definitions consistent with these terms were rated most favourably. Our findings show how body neutrality is perceived and used by experts and the general community. However, we question whether this conceptualisation is distinct from existing positive body image concepts.

Sport spectator well-being: a scoping review

ABSTRACT A clear understanding of sport consumer well-being is central to enriching research on the interaction between sport organizations and consumers, and more tangibly, to advancing public policy. This research offers a scoping review of existing studies on the well-being of sport spectators, resulting in the formulation of a Sport Spectator Well-being Process Model designed to direct future research endeavors. The review includes 76 peer-reviewed articles comprising reviews, qualitative and quantitative studies. A dual approach of frequency and thematic analysis was utilized to synthesize the findings. The frequency analysis highlighted an increasing trend in relevant publications over time, and the thematic analysis informed the development of a conceptual model of the four key stages of the sport spectator well-being process. The review also identified three significant research gaps: (1) the narrow scope of research contexts, (2) a limited range of theoretical frameworks employed and (3) challenges in research methodology. The findings significantly contribute to the transformative sport service research by integrating positive psychology concepts into the discourse on sport spectator well-being. The conceptual model is vital for researchers exploring the intricate relationship between sport spectatorship and spectator well-being, ensuring a comprehensive understanding of this significant topic.

Conceptions of Freedom in the Regulation of Junk Food and Tobacco

This paper examines the regulatory disparities between the junk food and tobacco industries in the UK, focusing on the underlying conceptions of freedom that shape public policy. While both industries contribute significantly to public health challenges, tobacco is subject to far stricter regulations. Through an analysis of parliamentary debates within the House of Commons, the paper explores the application of positive and negative freedom in discussions of junk food and tobacco. I find that the presence of addiction in tobacco discourse is used to apply a positive conception of freedom, leading to more stringent regulations. Conversely, junk food discussions emphasise individual choice, aligning with a negative conception of freedom and resulting in softer regulatory approaches. This paper argues that these differing narratives on freedom contribute to the observed regulatory differences and suggests that emphasising the addictive nature of junk food could shift regulatory perspectives.

A Closed-Form Solution to Observer Design Problem for Ostensible Metzler Takagi-Sugeno Systems

This paper addresses the state estimation problems related to the generalized fuzzy observer design for ostensible Metzler Takagi-Sugeno (T-S) systems. Attention is focused on design constraints for the concept of diagonal stabilization and positivity of observer gain matrices. On the basis of some new interpretations, the parameterizations of ostensible Metzler T-S fuzzy systems is presented, which opens the way to the solution of the design problem using only the principle of linear matrix inequalities. The same approach is intended to ensure the stability of the dynamics of the estimation error. The presented method extends and generalizes the results that have been presented in the literature so far.

How the Rejection of Incompatible Speech Acts Transforms Human Cognition

AbstractEngaging with the literature on transformative conceptions of rationality, I argue for the following position on the way reason transforms human cognition: when the capacity for knowing that one ought to do something is directed at one's own speech acts, an initially domain‐specific and practical grasp of genus/species relations – manifest in the ability to select among the various permitted ways to do as one judges one ought – becomes a mechanism through which the reflective study of genus/species relations hones the domain‐general classificatory abilities that accompany adult human language use. In this fashion, our instinctive behaviors may be transformed: we might cease to respond to events simply as (e.g.) fearful or enraging, recognize these motivations as cases of cowardice and recklessness, and begin to treat them as opportunities for courage and restraint.

ПІДВИЩЕННЯ ГАЛЬМІВНОЇ ЗДАТНОСТІ ЛОКОМОТИВА ПРОМИСЛО-ВОГО ТРАНСПОРТУ З УРАХУВАННЯМ ЗУСИЛЬ У ЙОГО ЗЧІПНИХ ПРИСТРОЯХ

Objective: substantiation the rational concept of increasing the braking capacity of the industrial locomotive in transient modes of train movement, taking into account the force factor in its coupling device. Methodology of the work: theoretical studies of the energy from the deformation of the coupling devices of the industrial locomotive in the transient modes of train movement; theoretical studies of excessive coupling of locomotive wheels with rails in the presence of force on the locomotive's coupling device; determination of kinematic and dynamic parameters of the transient mode of train movement. A mathematical model of the train motion transitory process has been developed, it using the example of locomotive braking process, which allows determining the current values of train element velocities, as well as coupling forces, and has a low average discrepancy with the data of the technological calculation of industrial locomotive. Fixed: the force on the coupling device of the locomotive changes with a high frequency. The braking process is conventionally divided into 3 stages, which are characterized by oscillations, stabilization and a drop in clutch force; the energy corresponding to the change in force in the clutch during braking falls on 90.5% of the first and second stages. Taking into account the obtained results, the conceptual adjustment of the force of the coupling of the wheel pairs of the locomotive with the rails at the level of the maximum forces in the coupling device of the locomotive, determined by the simulation results, is adopted. Scientific novelty: improvement of the method of determining the required force of the traction the wheels of locomotive with the rails by taking into account the energy corresponding to the change in the effort in the coupling device of the locomotive during the braking time of the train. Practical value: the development of an improved concept by regulating the force the traction of locomotive wheel pairs with rails in transient modes of train movement, taking into account the energy assessment of the effort in the locomotive's coupling device.

Towards a Conversational Ethics of Large Language Models

Abstract Large Language Models are one of the most prominent examples of current uses of AI, and one of the most urgently pursued normative tasks is to make them and their interactive user-interfaces—open-domain chatbots—safe. However, in this paper, we elaborate first on why such a limited view on the permissibility and desirability of their utterances falls conceptually flat, is philosophically insufficient, and leads to severe technological limits. We then propose a positive normative concept, appropriateness, that can provide the required orientation for determining what chatbots may or may not say, and distinguish between technical-discursive, social, and moral appropriateness. Lastly, we explore the requirements for social and conversational contexts to fulfill appropriateness-requirements, and find that positionality is a key element for their position in discourse.

Investigation of Academic Perseverance Levels of Gifted Students in Terms of Some Variables

With positive psychology, more focus is placed on the strengths of individuals. Thus, in recent years, it has been seen that features such as courage, optimism, hope, forgiveness, gratitude and perseverance have been the subject of more research. However, features associated with positive psychology have not been adequately studied in gifted students. In this study, perseverance, one of the positive psychology concepts, was discussed and academic perseverance in gifted students was examined. In this context, it is aimed to examine the academic perseverance levels of gifted students in terms of various variables. The study group of the research consists of 152 gifted students attending the 5th and 6th grades. The data in the study were collected with the Academic Perseverance Scale. Descriptive statistics and t-test were used in the analysis of the data. As a result of the analysis, when the findings of the study were examined, it was determined that the academic perseverance levels of the gifted students were above the average and high. It was observed that the academic perseverance levels of gifted students did not differ significantly according to gender and school type, but differed significantly according to grade level. The findings were discussed together with the studies in the current literature and suggestions were presented to researchers and practitioners.

Prompt-guided and multimodal landscape scenicness assessments with vision-language models.

Recent advances in deep learning and Vision-Language Models (VLM) have enabled efficient transfer to downstream tasks even when limited labelled training data is available, as well as for text to be directly compared to image content. These properties of VLMs enable new opportunities for the annotation and analysis of images. We test the potential of VLMs for landscape scenicness prediction, i.e., the aesthetic quality of a landscape, using zero- and few-shot methods. We experiment with few-shot learning by fine-tuning a single linear layer on a pre-trained VLM representation. We find that a model fitted to just a few hundred samples performs favourably compared to a model trained on hundreds of thousands of examples in a fully supervised way. We also explore the zero-shot prediction potential of contrastive prompting using positive and negative landscape aesthetic concepts. Our results show that this method outperforms a linear probe with few-shot learning when using a small number of samples to tune the prompt configuration. We introduce Landscape Prompt Ensembling (LPE), which is an annotation method for acquiring landscape scenicness ratings through rated text descriptions without needing an image dataset during annotation. We demonstrate that LPE can provide landscape scenicness assessments that are concordant with a dataset of image ratings. The success of zero- and few-shot methods combined with their ability to use text-based annotations highlights the potential for VLMs to provide efficient landscape scenicness assessments with greater flexibility.

Observation on Switching Properties of WO3-Based H2 Sensor Regulated by Temperature and Gas Concentration.

Transition metal oxide semiconductors have great potential for use in H2 sensors, but in recent years, the strange phenomena about gas-sensitive performance associated with their special properties have been more widely discussed in research. In some cases, the resistance of transition metal oxide gas sensors will emerge with some changes contrary to their intrinsic semiconductor characteristics, especially in gas sensor research of WO3. Based on the hydrothermal synthesis of WO3, our work focuses on the abnormal change of tungsten oxide resistance to different gases at low temperature (80-200 °C) and high temperature (above 200 °C). Through in situ FT-IR and in situ XPS, combined with density functional theory calculations, a new reasonable explanation of WO3 is proposed for the abnormal resistance change caused by temperature and the strange response due to gas concentration. The occurrence of these findings can be attributed to the synergistic effect resulting from the presence of two contributing factors. One of them is attributed to the alteration in the surface valence state of WO3 induced by gas, resulting in the reduction of W6+. The other one is due to the reaction between gas and adsorbed oxygen on the surface of WO3. This work presents a novel and rational concept for addressing the reaction mechanism between gas and transition metal oxide semiconductors, thereby paving the way for the development of highly efficient gas sensors based on transition metal oxide semiconductors.

Conceptions of aging and beliefs about how one's life is unfolding over time: A lifespan developmental perspective.

The present study examined beliefs about how one's life satisfaction is unfolding over time in relation to conceptions of aging in an online American adult lifespan sample (N = 882; Mage = 47.89, SD = 15.30, range = 19-84 years; 56% female). Single-item and multi-item ratings of recollected past, current, and anticipated future life satisfaction were employed, along with subjective perceptions of change in life satisfaction over time. Person-centered (latent profile) analysis identified distinct linear and nonlinear patterns of beliefs concerning past-current and current-future changes in life satisfaction: improve-improve, stable-stable, worsen-worsen, and worsen-improve. Multiple facets of conceptions of aging were assessed, including subjective perceptions of age (chronological vs. felt and desired age); attitudes toward, experiences of, and expectations concerning aging; future time perspective; and goal orientations (growth, maintenance, prevention of losses). Multinomial logistic regression models identified unique facets of conceptions of aging characterizing the four profiles. In general, individuals reporting a distinct profile conveying the belief that one's life was improving (vs. worsening) over time were characterized by more positive conceptions of aging. Further, conceptions of aging partially explained the link between chronological age and the belief that one's life is getting worse and worse (vs. better and better). Thus, the present work provides new insights into how age and conceptions of aging may shape the directions and patterns with which individuals view their lives to be unfolding over time.

Body Image and Eating Behaviour in Adolescents Loving Korean Wave Culture

The Korean wave has developed into a popular culture in the global community, especially adolescents in the last two decades. Cultural programs that include idols/bands, movies, dramas, variety shows, and webtoons are in great demand. The image of Korean women can influence adolescents' perceptions of ideal body shapes and eating behaviors. This study aims to analyze correlations between Korean culture viewing habits with body image and eating behavior among adolescents in West Java. This research is a cross-sectional study, conducted in West Java during April 2023 using the online structured questionnaire. The total subjects of this research were 467 adolescents. The results of the study stated that the subjects in this study were women (81.2%), college students (66.6%), Korean show enthusiasts (66.6%), Kpop enthusiasts (68.3%), Kdrama enthusiasts (77.5%), and webtoon enthusiasts (50.3%). Most of them thought that Korean idols were attractive (96.4%), and sometimes they want theirs body shape as their idols (46.5%). There were differences in body image and eating behavior among K-show (p=0.046 & p=0.039), Kpop (p=0.048, p=0.027, p=0.024, & p=0,000), and Kdrama enthusiasts (p=0.026) but there were no differences between enthusiasts of webtoon. Our findings show the Korean wave culture is one of the causes of adolescents experiencing body dissatisfaction, which is an important predictor of eating problems. Awareness of the importance of positive body image and healthy weight control behavior concepts is necessary.

First, it underscores the era’s fervent drive for rapid modernization, rooted in emulation of Western models perceived as progressive. Second, using a historical narrative approach, this research highlights the pivotal role of foreign expertise in catalyzing and formalizing rationalization efforts.Originality/valueThis study makes a unique and meaningful contribution to the history of management in terms of demonstrating the international influence of the Scientific Management Movement through the neglected case of Turkey.

Suffering in the doctor-patient relationship: Medicine as the science of suffering

In medical science today, much attention is paid not only to what can be experimental, reproducible, observable or describable in data, but also to what concerns the subjectivity of the physician and the patient. We thus break away from a positivistic conception that does little to illuminate our path in this order of phenomena to enter with an observation that wants to be phenomenological into what seems to best characterise the meaning of Medicine and that from bio-science reveals it to us as anthropo-science, a science of man-for-man.

What it Takes to be a Good International Chinese Teacher

After the recovery of international Chinese education in 2023, the demand for international Chinese teachers overseas has returned, which also means that the demand for truly excellent international Chinese teachers has also begun to rise. As a student who is about to become an international Chinese teacher, how to become an excellent international Chinese teacher and complete the teaching mission of an international Chinese teacher is the main issue worthy of deep consideration. Thinking about this issue can be carried out throughout the student's learning life and into future teaching activities. "The unity of knowledge and action" is the most common point in Chinese philosophical wisdom, and it is also the most difficult point to achieve in practical activities. As an excellent international Chinese teacher, we must achieve the "unity of knowledge and action", clarify the teaching mission in the teaching process, take positive and correct concepts as the guide, and truly achieve the responsibility and mission of "language teaching and cultural dissemination" that a Chinese language teacher should do, so as to promote the development of Chinese to the world and expand more possibilities for exchanges between China and the world.

Conceptualising project environmental impact assessment for enhancement: no net loss, net gain, offsetting and nature positive

ABSTRACT With declining biodiversity worldwide, the need for development proposals to deliver positive, not negative, environmental outcomes is clear. Arguably, this is a long-standing goal of environmental impact assessment (EIA). This article explores the extent to which current project EIA practice can achieve enhancement, no net loss or a net gain of biodiversity and Nature Positive goals. Using reflexivity, a conceptual approach is applied to policies and examples from practice. The environmental enhancement goal of EIA is explained. The mitigation hierarchy is applied to a hypothetical mining example for accomplishing no net loss/net gain of biodiversity through offsets. Nature Positive is examined in relation to current EIA expectations and how it differs from the other positive outcomes concepts. To overcome the ‘controlled loss’ paradigm that typifies EIA practice, a major mindset change is needed. Recommendations include: (i) placing ‘enhance’ on top of the mitigation hierarchy; (ii) ensuring policies uphold ‘true offsets’ with provision to ‘say no’ to development for high biodiversity areas and performance outcomes accountability and (iii) developing legislative provisions for Nature Positive and how project EIA should address it. Practitioners are urged to ‘step up’ in their personal endeavours to advocate for such changes to deliver positive outcomes from EIA.

Three-way concept lattice from adjunctive positive and negative concepts

Three-way concept lattices (TCLs) have been widely explored due to their clear hierarchical structures, concise visual description and good interpretability. In contrast to classic formal contexts, lattice-valued fuzzy contexts exhibit great capability in describing and representing concepts with uncertainty. Different from conventional approaches to research of TCLs, this paper focuses on investigating the algebraic structure and properties of three-way concept lattice (TCL) stemmed from the positive concept lattice and negative concept lattice in a lattice-valued formal context. Several associated concept lattices such as the Cartesian product of positive concept lattice and negative lattice (i.e., pos-neg lattice), lattices induced from the partition of the pos-neg lattice, and their relationship are explored. Specifically, the isomorphism, embedding and order-preserving mappings between them are built. The quotient set of pos-neg lattice when being defined a specific equivalence relation on it is a complete lattice and each equivalence class is a lower semi-lattice. It is further declared that the structure of TCL is intrinsically and determined wholly by the pos-neg lattice. A practical application of the built theory of TCL is provided to sort alternatives in multi-criteria decision making.

Happiness across the borders-A cross-sectional study among patients with psoriasis and atopic dermatitis in Europe.

Dermatological research has traditionally concentrated on evaluating mental comorbidities, neglecting positive concepts like happiness. Initial studies indicate that psoriasis and atopic dermatitis (AD) impair the happiness of those affected. Considering global happiness variations, this study aimed to explore the disease- and country-specific differences in disease-related quality of life and happiness, and potential influential factors on heuristic happiness among psoriasis and AD patients in Europe. A cross-sectional multicentre study was conducted in dermatology departments of university-affiliated hospitals in eight European countries (Austria, Germany, Italy, Malta, Poland, Portugal, Romania and Ukraine) between October 2021 and February 2023. Adult psoriasis and AD patients completed a standardized questionnaire in their native languages, providing data on demographics, disease-related characteristics, disease-related quality of life (Dermatology Life Quality Index, DLQI), heuristic happiness, positive affect (PA), negative affect (NA) and satisfaction with life (SWL). Descriptive analysis and quantile regression were performed. Between psoriasis (n = 723) and AD (n = 316) patients almost no differences were observed in happiness, SWL and NA, except for DLQI and small differences in PA, with AD patients reporting greater impact than psoriasis patients. Country-wise variation emerged in DLQI, heuristic happiness, PA, NA and SWL with Austrian patients displaying the highest levels of happiness, satisfaction and positivity, coupled with higher treatment care and lower disease severity. Quantile regression revealed varying coefficients for predictor variables across quantiles, indicating, for example positive effects on heuristic happiness associated with current or previous receipt of systemic therapies at different quantiles. This study shows notable happiness differences across European countries and significant disease-related variations, particularly with AD patients being more impaired than psoriasis patients. The findings highlight the need for equality in treatment access and support the development of targeted positive psychological interventions to enhance happiness considering country-specific distinctions in future research and health policies for psoriasis and AD patients.

Nostalgic consumer trends and nostalgia marketing

Over the last few years, we have observed an intensification of nostalgic consumer trends manifested through choices and behaviors that reflect sentimental attachments to the past. In parallel, we increasingly note a growing presence of marketing activities that tap into the emotions and experiences tied to consumers’ memories. These efforts link brands and their campaigns to positive concepts or ideas from the past. Nostalgia marketing relies on evoking positive feelings about the past and applies to products, marketing communications, and brand experiences. The article seeks to identify trends based on nostalgia, both in terms of consumer behavior and marketing practice. The author presents the essence of nostalgia marketing and the research domains on nostalgic consumer behavior. The article describes nostalgic consumer trends in the context of their determinants. It identifies nostalgic strategies and trends in contemporary marketing practice. The objectives are realized based on a literature review supported by bibliographic analysis, desk research based on available quantitative and qualitative research results, and content analysis of campaigns promoting nostalgic products and using themes and content related to nostalgia marketing. Insights on nostalgic trends and marketing approaches provide the basis for identifying practical and research recommendations.

Efficiency and the core in NTU games in partition function form

AbstractThe aim of this paper is to establish a necessary and sufficient condition for the non-emptiness of the core in NTU games in partition function form, given an externality scheme $$ f \in \textsf{Ex}(N) $$ f ∈ Ex ( N ) . We extend the notion of convexity to incorporate externality effects. By introducing a new concept of rationality, called collective rationality, we demonstrate the efficiency of the grand coalition $$ N $$ N . We also identify a sufficient condition for the efficiency of the grand coalition using the property of individual superadditivity.
