The article aims to study the demand for sparkling wines in Europe. The main objective is to estimate the classic demand parameters aggregately for the entire European area (European Union and the United Kingdom) and separately for groups of countries characterized by wine markets with similar characteristics.

Using 15-years market data for different wine categories from the Euromonitor Passport database, the estimation of price and income elasticities is performed through a Quadratic Almost Ideal Demand System. In line with the objectives, the model is applied first to the whole European area and then separately to the considered groups of countries (subareas). To identify homogeneous subareas, a cluster analysis was performed on basic characteristics of the wine market.

When considering the European market as a whole, sparkling wines should be considered a luxury category with a high own-price elasticity. However, the structure of their demand is rather different in different sub-areas. The observed heterogeneity suggests that differentiated policy and marketing considerations should be made. In addition, it widens the possibilities for producers, who can choose the submarkets that respond best to their needs to export their sparkling wines. This seems particularly important in markets, like the sparkling wine ones, that are experiencing a continuous expansion over the last decades.

Despite using a methodology well-established to study wine and alcohol demand, the study fills a considerable gap in the literature. Although the demand for sparkling wine is growing worldwide, so far only a couple of studies have engaged in the analysis of its structure. In Europe, the largest market for sparkling wine, this kind of studies is completely lacking.

Freezing extends the shelf life of food. Home freezing of fresh foods and the purchase of frozen foods have been advocated as approaches to reduce food waste in US households. This paper discusses how commonly US households apply these practices, quantifies frozen food waste and relates these practices to food waste.

We add questions to the summer 2022 wave of the US Household Food Waste Tracking Survey. The novel survey data provide important baseline information and household behaviours, such as food waste, home freezing of fresh food and the purchase of frozen foods. We analyse the association among these behaviours from more than 1,000 US households.

We find that US household wastes about 26 g per person per week of food that was once frozen, which is about 6% of all household food waste. The finding indicates that a small portion of food waste in US households comes from frozen food. Vegetables and meats are the most commonly discarded frozen foods. Among the frozen items reported as discarded, about 30% were purchased as frozen rather than purchased fresh and then frozen at home by the consumer and about 30% more were reported as discarded from the refrigerator rather than directly from the freezer. The findings are important for informing strategies to reduce household food waste.

While the data provide important baseline information and correlate the use of freezing with lower waste levels, more work is needed to understand if interventions encouraging frozen food purchase or home freezing would reduce household food waste.

We provide unique, detailed information about the quantity of frozen food waste in US households and the relationships between consumer food waste and the practices of frozen food purchasing and home freezing.

This study aims to investigate the impact of an emotional support training program on weight self-stigma and body image among women with polycystic ovary syndrome (PCOS).

A randomized controlled trial was conducted with 200 women diagnosed with PCOS employing a pretest-posttest design. The experimental group, consisting of 100 women, participated in an emotional support training program and received an informational booklet, while the control group (100 women) received only the booklet. Pre- and post-intervention assessments were conducted using weight self-esteem and body shape questionnaires.

The results demonstrated a statistically significant difference in weight self-stigma and body shape scores between the experimental and control groups following the intervention. For both the immediate post-intervention test [t(198) = 31.1, p = 0.01] [t(198) = 31.1, p = 0.01] [t(198) = 31.1, p = 0.01] and [t(198) = 60.7, p = 0.01] [t(198) = 60.7, p = 0.01] [t(198) = 60.7, p =0.01], as well as the delayed post-intervention test [t(198) = 32.3, p = 0.01] [t(198) = 32.3, p = 0.01] [t(198) = 32.3, p = 0.01] and [t(198) = 70.9, p = 0.01] [t(198) = 70.9, p = 0.01] [t(198) = 70.9, p = 0.01], the experimental group exhibited lower mean scores. Specifically, the experimental group scored 20.3 ± 9.2 for immediate and 20.4 ± 9.3 for delayed assessments on weight self-stigma, and 101.2 ± 7.2 for immediate and 86.5 ± 7.6 for delayed assessments on body shape. In contrast, the control group scored 159.8 ± 6.3 for immediate and 157.6 ± 6.4 for delayed assessments, respectively.

Nurses should be aware of the adverse effects of PCOS and associated obesity on weight self-stigma and body image. They are encouraged to develop targeted emotional support training programs specifically designed to address weight self-stigma and body image concerns in women with PCOS.

This study confirms the effectiveness of an emotional support training program in mitigating the negative effects of weight-related stigma and improving body image perception.

The purpose of this study is to test whether presenting organizational change in a way that promotes the status quo will result in increased employee support for the change.

Using quantitative methodology, categorical data were collected through an online cross-sectional survey in which 222 adult respondents participated. The items used vignette-based question blocks with fixed response options. Item responses were analyzed using an exact binomial test – focusing on the relationship between status quo bias and other responses to change communications.

The findings demonstrated that status quo bias has an association with employee sensemaking. These results suggest that status quo bias can be utilized by organizational leaders and change practitioners to endorse change efforts. Furthermore, it not only appears that promoting what is staying the same but also including a small reason to justify the change can bring additional advantage. Advertising a vision of radical transformation is problematic as it may actually heighten employee resistance.

This research explores and presents a convergence between organizational change management and behavioral economics – specifically, status quo bias. No other comparable study collecting data across a number of organizational change themes and critiquing existing change management models could be found during the preparation of this research effort.

The purpose of this empirical study was to test whether presenting organizational change in a way that enhances employee self-worth will result in increased employee support for the identified change. In doing so, we developed a new measure, which includes a novel baseline element.

Items were developed, and then categorical validation data were collected through an online cross-sectional survey in which 222 respondents (adults over 18 years of age, and at least 6 months tenure) participated.

Within the items, we framed the activation of self-worth bias as requests for employee comments regarding change efforts. Results indicate there is a difference between asking for employee comment on change efforts, compared to asking for employee comment on change efforts and also providing feedback considerate of that input.

This study explores and presents a convergence between behavioral economics, management and applied psychology research – using both self-worth bias, and organizational change management communications; no other such comparable study or analysis could be found during the preparation of this research effort. Furthermore, a novel measure and innovative method is presented for developing and measuring self-worth bias during organizational change management communications.

This chapter introduces EmoGenPath, an innovative machine learning-based model designed to deliver adaptive therapy to children and youth affected by the trauma of armed conflict. The model synthesizes advanced artificial intelligence (AI) techniques, including convolutional neural networks for emotion recognition and an advantage-actor critic-trained reinforcement learning model for therapeutic content tailoring toward goal achievement, to provide a dynamic and personalized therapeutic experience. Recognizing the importance of empathetic and culturally sensitive interventions, EmoGenPath offers a unique approach by prioritizing the emotional states and individual narratives of its users. In regions where conflict has impeded traditional mental health services, this model aims to bridge the gap, facilitating resilience and recovery through a virtual therapeutic environment that can be accessed via low-bandwidth internet connections, ensuring broader reach and impact. This chapter emphasizes the ethical implementation of AI in sensitive settings. It discusses the imperative of privacy, security, and inclusive design, ensuring that the model is responsive to diverse emotional expressions across different ethnicities and backgrounds. Additionally, it outlines the potential of such a model to scale therapeutic resources effectively, delivering tailored interventions with a compassionate approach.

The chapter examines the relevance of systematic inquiries as part of a holistic approach to safeguarding. Based on sociological approaches on silence in organisations and against the background of the concept of transitional justice, it is demonstrated that the importance of systematic inquiries for the development of a critical momentum is to be highly valued if sport organisations want to seize the chance to transform. Inquiries uncover voice-inhibiting and abuse-permissive structures in sports organisations and, in this way, help to initiate transformations in the sports system. For victims of abuse, inquiries play an important role in helping them to realise their right to receive the truth, as well as initiating a process of reconciliation. To achieve this, it is essential that inquiries pursue a survivor-based and participatory approach. This is demonstrated in the chapter, using the example of an inquiry conducted in Germany.

Climbing ropes are made to withstand severe stresses and absorb energy during fall, reducing the impact force on the climber and their equipment. Natural fibres like hemp and sisal have been mostly substituted by synthetic fibres like nylon, polyester and aramid fibres, which provide greater strength, durability and flexibility. The performance of climbing ropes can deteriorate due to moisture exposure, UV radiation and abrasion during outdoor activities.

This review examines the transition from natural to synthetic fibres and advances in material and construction techniques. The analysis also examines how construction methods, ranging from traditionally laid ropes to current braided kernmantle designs, affect rope strength, elasticity and handling qualities. Furthermore, the paper analyses how the fibres influence the rope’s behaviour under various conditions, such as dynamic loading, wear and tear, fatigue and exposure to environmental variables such as moisture, temperature and UV light.

Ropes should have lower peak forces and greater dynamic elongations, resulting in decreased maximum accelerations, increased energy absorption, reduced jerk and lower forces on safety components during fall arrest. It gives recommendations for future research areas to optimize climbing rope design.

The systematic literature review in this study is focused on the performance of climbing ropes, including the raw materials and construction, as well as the impact of weathering and service conditions.

Previous discussions have characterized hookup culture as ambiguous by nature, but social psychological theory tells us people dislike ambiguity in practice. Meanwhile, a myriad of undefined relationship terms (e.g., talking to, hanging out, having a thing) arose and have remained in use. I examine (1) whether these different “situationship” labels have distinct affective meaning and (2) what that suggests for those occupying the concomitant identities (i.e., assess the behavioral and emotional consequences of being “someone in a _____ relationship”).

Using affect control theory and a sample of young adults in defined (N = 50) and undefined (N = 43) relationship types, I test if affective ratings of various relationship label identities are statistically distinct. I then computationally model social events with each relationship label as actor (X identity performs [behavior]), compare their differing levels of social discomfort, and empirically predict the emotions each identity would feel.

Undefined relationship labels are not synonymous. Correspondingly, the nature, emotions, and expected behaviors of the individuals with those labels' related relational identities are not equivalent. In cultural evaluation, all undefined relationship labels are lower than all defined relationship labels. In event simulations, predicted deflection levels and actor consequent emotions (how normative is it and how jarring does it feel) were patterned by the labels' cultural evaluation ratings, these correlate with relationship commitment level.

By interpersonal necessity, individuals make fine distinctions in shared meanings within a cultural context of constant redefinition. Physically and emotionally negative behaviors are culturally more expected and accepted in undefined contexts by the culturally-understood nature of – and shared perspectives of participants concerning – those relationships’ parameters.

The purpose of this article is to synthesize the topics, conceptualizations and measurements of value-based management (VBM) and to suggest a research agenda covering its next evolution as sustainable governance.

The authors conducted a systematic literature review of 80 seminal studies published between 1979 and 2022. The authors synthesized the studies by their conceptualizations of VBM in an inductively developed framework.

The authors find that scholars explore diverse topics related to VBM with a prevailing focus on shareholder primacy. There is a paucity of studies that focus on the integration of shareholder maximization and stakeholder management practices. The authors explain which studies will form a promising foundation for advanced research on sustainable governance that will reach beyond current VBM research.

The authors' research agenda addresses new future topics on conflicting goals within and between shareholder groups, offers specific suggestions for using new research methods and untapped data sources for VBM and paves the way to substantially extend the boundaries of the firm in VBM research to include stakeholders, strategic alignment and new sustainability measures.
