Today's youth form a crucial target group for intervening in unsustainable overconsumption habits and for setting the path and ideas on responsible living. This article explores young people's motivations for engaging in three behavioural patterns linked to anti-consumption (voluntary simplicity, collaborative consumption, and living within one's means) in relation to sustainability. Applying a qualitative approach, laddering interviews reveal the consequences and values behind the anti-consumption behaviours of young people of ages 14 to 24 according to a means-end chains analysis. The findings highlight potential for and the challenges involved in motivating young people to reduce material levels of consumption for the sake of sustainability. Related consumer policy tools from the fields of education and communication are identified. This article provides practical implications for policy makers, activists, and educators. Consumer policies may strengthen anti-consumption among young people by addressing individual benefits, enabling reflection on personal values, and referencing credible narratives. The presented insights can help give a voice to young consumers, who struggle to establish themselves as key players in shaping the future consumption regime.}, language = {en} } @article{ZahediOeznurAkalinLawrenceetal.2023, author = {Zahedi, Anoushiravan and {\"O}znur Akalin, Renin and Lawrence, Johanna E. and Baumann, Annika and Sommer, Werner}, title = {The nature and persistence of the effects of posthypnotic suggestions on food preferences}, series = {Frontiers in psychology}, volume = {14}, journal = {Frontiers in psychology}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2023.1123907}, pages = {19}, year = {2023}, abstract = {The persistence of food preferences, which are crucial for diet-related decisions, is a significant obstacle to changing unhealthy eating behavior. To overcome this obstacle, the current study investigates whether posthypnotic suggestions (PHSs) can enhance food-related decisions by measuring food choices and subjective ratings. After assessing hypnotic susceptibility in Session 1, at the beginning of Session 2, a PHS was delivered aiming to increase the desirability of healthy food items (e.g., vegetables and fruit). After the termination of hypnosis, a set of two tasks was administrated twice, once when the PHS was activated and once deactivated in counterbalanced order. The task set consisted of rating 170 pictures of food items, followed by an online supermarket where participants were instructed to select enough food from the same item pool for a fictitious week of quarantine. After 1 week, Session 3 mimicked Session 2 without renewed hypnosis induction to assess the persistence of the PHS effects. The Bayesian hierarchical modeling results indicate that the PHS increased preferences and choices of healthy food items without altering the influence of preferences in choices. In contrast, for unhealthy food items, not only both preferences and choices were decreased due to the PHS, but also their relationship was modified. That is, although choices became negatively biased against unhealthy items, preferences played a more dominant role in unhealthy choices when the PHS was activated. Importantly, all effects persisted over 1 week, qualitatively and quantitatively. Our results indicate that although the PHS affected healthy choices through resolve, i.e., preferred more and chosen more, unhealthy items were probably chosen less impulsively through effortful suppression. Together, besides the translational importance of the current results for helping the obesity epidemic in modern societies, our results contribute theoretically to the understanding of hypnosis and food choices.}, language = {en} } @article{WotschackVladovadePaivaLareiroetal.2022, author = {Wotschack, Philip and Vladova, Gergana and de Paiva Lareiro, Patricia and Thim, Christof}, title = {Learning via assistance systems in industrial manufacturing}, series = {Journal of workplace learning}, volume = {35}, journal = {Journal of workplace learning}, number = {9}, publisher = {Emerald}, address = {Bradford}, issn = {1366-5626}, doi = {10.1108/JWL-09-2022-0119}, pages = {235 -- 258}, year = {2022}, abstract = {Purpose The purpose of this paper is to investigate how learning solely via an assistance system influences work performance compared with learning with a combination of an assistance system and additional training. While the training literature has widely emphasised the positive role of on-the-job training, particularly for groups that are often underrepresented in formalised learning situations, organisational studies have stressed the risks that emerge when holistic process knowledge is lacking and how this negatively affects work performance. This study aims at testing these negative effects within an experimental design. Design/methodology/approach This paper uses a laboratory experimental design to investigate how assistance-system-guided learning influences the individuals' work performance and work satisfaction compared with assistance-system-guided learning combined with theoretical learning of holistic process knowledge. Subjects were divided into two groups and assigned to two different settings. In the first setting, the participants used the assistance systems as an orientation and support tool right at the beginning and learned the production steps exclusively in this way. In the second setting, subjects received an additional 10-min introduction (treatment) at the beginning of the experiment, including detailed information regarding the entire work process. Findings This study provides evidence that learners provided with prior process knowledge achieve a better understanding of the work process leading to higher levels of productivity, quality and work satisfaction. At the same time, the authors found evidence for differences among workers' ability to process and apply this additional information. Subjects with lower productivity levels faced more difficulties processing and applying additional process information. Research limitations/implications Methodologically, this study goes beyond existing research on assistance systems by using a laboratory experimental design. Though the external validity of this method is limited by the artificial setting, it is a solid way of studying the impact of different usages of digital assistance systems in terms of training. Further research is required, however, including laboratory experiments with larger case numbers, company-level case studies and analyses of survey data, to further confirm the external validity of the findings of this study for the workplace. Practical implications This study provides some first evidence that holistic process knowledge, even in low-skill tasks, has an added value for the production process. This study contributes to firms' training policies by exploring new, digitalised ways of guided on-the-job training and demonstrates possible training benefits for people with lower levels of (initial) abilities and motivation. Social implications This study indicates the advantage for companies and societies to invest in additional skills and training and points at the limitations of assistance systems. This paper also contributes to training policies by exploring new, digitalised ways of guided on-the-job training and demonstrates possible training benefits for people with lower levels of (initial) abilities and motivation. Originality/value This study extends existing research on digital assistance systems by investigating their role in job-related-training.

Therefore, this paper seeks to develop a better theoretical understanding of how users respond to envy on SNSs. We review literature on envy in offline interactions to derive three behavioral strategies to reduce envy, which we then transfer to the SNS context (self-enhancement, gossiping, and discontinuous intention). Further, we propose a research model and examine how culture, specifically individualism-collectivism, affects the relationship between envy on an SNS and the three strategies. We empirically test the variance-based structural equation model through survey data collected of Facebook users from Germany and Hong Kong.

A promising intervention is nudging, which uses insights from behavioral economics to gently nudge individuals toward more sustainable choices. In this study, we investigate how modifying digital choice architectures with nudges can be used to influence consumer energy conservation behavior in smart home applications (SHAs).

In contrast, given high levels of leader negative mood, functional diversity was positively associated with information elaboration in teams.

This study highlights the value of examining seemingly contradictory leadership aspects in the effort to gain a fuller understanding of how to foster performance in diverse teams. Practitioner points To effectively lead diverse teams, leaders need to navigate between the need to promote unique ideas (i.e., information elaboration) and the simultaneous need to pull together diverse members towards a common identity. Leader mood addresses both of these needs. When the team leader exhibited a positive mood, team functional diversity was positively related to members' identification with the team. By contrast, when the team leader displayed a negative mood, team functional diversity was positively related to information elaboration. Over a 12-day period, diverse teams performed best when the leader showed both positive and negative mood.

Intentional forgetting is the basis of any adaptation to change, as it ensures that nonprevailing memory items are not retrieved while prevailing ones are retained. This study presents a novel experimental approach that was introduced in a learning factory (the Research and Application Center Industry 4.0) to investigate intentional forgetting as it applies to production routines. In the first experiment (N = 18), in which the participants collectively performed 3046 routine related actions (t1 = 1402, t2 = 1644), the results showed that highly proceduralized actions were more difficult to forget than actions that were less well-learned.

Materials and methods We identified patients with chronic obstructive pulmonary disease in a German health insurance claims database with 6.5 million individuals and divided them into a group of patients with the highest disease severity and a group of control patients with lower severity. We then used gradient boosting with stability selection to determine variables correlating with a chronic obstructive pulmonary disease diagnosis of highest severity and subsequently model the temporal progression of the disease using the selected variables. Results We identified a network of 20 diagnoses (e.g. respiratory failure), medications (e.g. anticholinergic drugs) and procedures associated with a subsequent chronic obstructive pulmonary disease diagnosis of highest severity. Furthermore, the network successfully captured temporal patterns, such as disease progressions from lower to higher severity grades. Discussion The temporal trajectories identified by our data-driven approach are compatible with existing knowledge about chronic obstructive pulmonary disease showing that the method can reliably select relevant variables in a high-dimensional context.

To address this challenge, deep learning methods were increasingly deployed due to their optimization and scalability properties. However, these approaches were often tested in specific operational applications and focused on technical performance indicators such as order tardiness or total throughput. In this paper, we propose a deep reinforcement learning based production control to optimize combined techno-financial performance measures.

To address this challenge, we propose a hyper-heuristics control model within a semi-heterarchical production system, in which multiple manufacturing and distribution agents are spread across pre-defined modules. The agents employ a deep reinforcement learning algorithm to learn a policy for selecting low-level heuristics in a situation-specific manner, thereby leveraging system performance and adaptability. We tested our approach in simulation and transferred it to a hybrid production environment. By that, we were able to demonstrate its multi-objective optimisation capabilities compared to conventional approaches in terms of mean throughput time, tardiness, and processing of prioritised orders in a multi-layered production system.

The proposed multistage theory of differential effects distinguishes a participation stage, when consumers decide whether to purchase organic at all, and an expenditure stage, when consumers decide about how much of their budget to spend on organic products across purchases. An analysis of shopping patterns of approximately 14,000 households confirms the proposed differential influences: Other-oriented motives (care for others and the environment) support participation but impede sustained expenditures. Only self-oriented motives (hedonism) foster both participation and expenditures.

With regard to a proposed model of five academic competencies(time management, learning skills, technology proficiency, self-monitoring, and research skills), incoming students' perceptions concerning academic staff support and students' selfreported confidence at a German university were examined. Using quantitative data, an initial exploratory study was conducted (N = 155), which revealed first-year students' perceptions of the role of academic staff in supporting their development, especially in research skills, as well as low self-reported confidence in this competence. Thus, a follow up study (N = 717) was conducted to confirm these findings as well as to provide an indepth understanding of research skills. Understanding students' perceptions is crucial if higher education institutions are to meet students' needs and provide adequate support services in the challenging first year.

In addition, the strength of the relationship for such factors and intentions to start new ventures was determined through the moderator role of easy access to venture capital. Design/methodology/approach: To this end, this study complements the academic literature by integrating the structural equation modeling (SEM) and multiple-criteria decision-making (MCDM) techniques. Thus, the MCDM (i.e. analytic hierarchy process and vlsekriterijumska optimizcija i kaompromisno resenje [VIKOR]) is an effective approach to solving the problem of complexity and evaluation (i.e. multiple evaluation criteria, important criteria and data variation). Hence, to complete the strategic guideline solution, this study uses a survey for collecting data from 202 immigrants in Malaysia, Pakistan, Nigeria and Singapore. Findings The results from SEM prove several critical factors of immigrants' entrepreneurs. These factors of immigrants' entrepreneurs can be vital for academics and host countries. By focusing on these aspects and by developing some personality traits (such as self-efficacy and optimal personality traits), these factors can contribute a good deal to increasing the capabilities of immigrant's entrepreneurs toward entrepreneurial intentions. In the validation, the statistical objective method indicates that the immigrants' prioritizations in all countries are supported by the systematic ranking. Thus, entrepreneurial intentions for immigrants can pursue the order proven by the VIKOR results.

For the MCDM methods, ranking energy companies according to the circular economy can support policymakers' decisions to renew contracts with leading companies in the ranking. Practitioners can also impose government regulations on low-ranked companies. Thus, governments can reduce the problems of greenhouse gas emissions and other environmental pollution.}, language = {en} } @article{KhawAlnoorAlAbrrowetal.2022, author = {Khaw, Khai Wah and Alnoor, Alhamzah and Al-Abrrow, Hadi and Tiberius, Victor and Ganesan, Yuvaraj and Atshan, Nadia A.}, title = {Reactions towards organizational change}, series = {Current psychology}, journal = {Current psychology}, publisher = {Springer}, address = {New York}, issn = {1046-1310}, doi = {10.1007/s12144-022-03070-6}, pages = {1 -- 24}, year = {2022}, abstract = {Regardless of the prevalence and value of change initiatives in contemporary organizations, these often face resistance by employees.

Based on a means-end chain approach, this study investigates consumer cognitive decision-making structures related to six distinct options for economically (non-)sustainable consumption. Whereas saving motives, waste concerns, and avoidance motivations support economically sustainable decisions, economically non-sustainable decision-making is directly linked to attaining overall life goals.

A general reduction in consumption levels is considered necessary to attain global sustainability goals. However, knowledge regarding the factors driving people to deliberately consume less and how anti-consumption affects individuals' well-being is limited. Against this background, this study considers the influence of human values and the well-being effects of two types of anti-consumption: voluntary simplicity and collaborative consumption. Based on representative data from the US (N = 1075) and Germany (N = 1070), the findings show that the two anti-consumption types do not reduce the well-being of individuals' but in some cases, even improve it, which suggests that lowering consumption can not only help protect environmental resources but also serve the greater good of society. In particular, this relationship holds among collaborative consumers with a strong need for cognition, i.e., a cognitive thinking style that involves a high level of decision control. According to the study results, opposite value orientations are the drivers of voluntary simplicity and collaborative consumption (i.e., a focus on self-transcendence versus self-enhancement).

Based on data gathered before and near the end of the first pandemic lockdown in Germany in spring 2020, this research demonstrates that ecological, social, and voluntary simplicity consciousness deteriorated in the minds of sustainability-conscious consumers, with notable impacts on their willingness to spend sustainably and their shopping affinity.

Blockchain-based applications will integrate Internet of Things devices in the power grid, manage the e-mobility infrastructure, automate billing and direct payment and issue certificates regarding the origin of electricity. Blockchain solutions are expected to play an important big role in fostering peer-to-peer trading in microgrids, further democratizing and decentralizing the energy sector. New regulatory frameworks become necessary. Research limitations/implications: The Delphi study's scope is rather broad than narrow and detailed. Further studies should focus on partial scenarios.

This paper fills this void and develops a framework suggesting that the extent to which consumers translate their concerns and obligations for society into a willingness to boycott and/or buycott is bounded by self-interest. Using a unique, representative sample of 1833 German consumers, this study reveals that the effects of environmental concerns and universalism on buycotting are amplified by hedonism, while the effects of social concern on buycotting and boycotting are attenuated by hedonism and simplicity, respectively.

Using verbal and graphic elements, they provide simplified representations of reality and can support BM tasks that go beyond working memory's capacities. Visualisations thus reduce cognitive load and represent how practitioners and researchers think about BMs. However, they can also affect their thinking. This constitutes a thus far insufficiently explained tension between effectively reducing reality's complexity and the resulting cognitive biases. Building on cognitive load and framing theory, we qualitatively analysed 103 BM visualisations to explain how visual elements affect visualisations' cognitive effectiveness (helpfulness and ease of applicability) and unfold visual framing effects. By identifying five visual framing effects, we contribute to the cognitive BM perspective and explain how this set of cognitive factors affects BM management and research. We also found that most BM visualisations are not cognitively effective because they consist of unclear and non-parsimonious elements, limiting their cross-contextual application. Furthermore, the analysis revealed certain visualisations with strictly operationalised BM dimensions. These findings provide essential contributions to the literature on BM methods.

First, a large collection of email newsletters is analyzed to show the wide usage of tracking over different countries, industries and time. Second, we propose a set of features geared towards the identification of tracking images under real-world conditions. Novel features are devised to be computationally feasible and efficient, generalizable and resilient towards changes in tracking infrastructure. Third, we test the predictive power of these features in a benchmarking experiment using a selection of state-of-the-art classifiers to clarify the effectiveness of model-based tracking identification.
