For efficient energy distribution, microgrids provide significant assistance to main grids and act as a bridge between the power generation and consumption. Renewable energy generation resources, particularly photovoltaics, are considered as a clean source of energy but are highly complex, volatile, and intermittent in nature making their forecasting challenging. Thus, a reliable, optimized, and a robust forecasting method deployed at MG objectifies these challenges by providing accurate renewable energy production forecasting and establishing a precise power generation and consumption matching at (...) MG. Furthermore, it ensures effective planning, operation, and acquisition from the main grid in the case of superior or inferior amounts of energy, respectively. Therefore, in this work, we develop an end-to-end hybrid network for automatic PV power forecasting, comprising three basic steps. Firstly, data preprocessing is performed to normalize, remove the outliers, and deal with the missing values prominently. Next, the temporal features are extracted using deep sequential modelling schemes, followed by the extraction of spatial features via convolutional neural networks. These features are then fed to fully connected layers for optimal PV power forecasting. In the third step, the proposed model is evaluated on publicly available PV power generation datasets, where its performance reveals lower error rates when compared to state-of-the-art methods.

Organizational members are likely to harbor different allegiances, values, and identifications that can affect how they respond to their organization’s stigmatization. Drawing on the empirical case of a public broadcaster in South Korea initially stigmatized for its association with an authoritarian government, we focus on the responses of different intra-organizational groups to stigma and their interactions with each other and with external audiences. We find that faced with stigma, groups in the organization were divided about how to respond, with those (...) defying the stigma and advocating a close relationship with the government competing with those who shared the values of stigmatizing audiences. Both groups sought control over journalism work, the organizational attribute for which the broadcaster was stigmatized, allying with external audiences that shared their respective visions. The dominance of the group that defied the stigma led to increased stigmatization of the organization by existing audiences and additionally prompted the participation of initially passive audiences in its denigration, eventually leading to organizational decline. We contribute to the literature on stigma by promoting an understanding of heterogeneity among members in stigmatized organizations and its implications for the consequences of stigma. We also contribute to theorizing stigmatization as a relational process by demonstrating how the heterogeneity of organizational members’ experience of stigma interacted with audience heterogeneity and highlighting the relative roles played by active and passive audiences in bringing about the decline of a stigmatized organization.

This study analyses the types and frequencies of ethical dilemmas and the rationale of ethical decision making in student nurses; it also evaluates their decision making. One hundred senior student nurses who were enrolled in a two-credit course in nursing ethics were asked to provide an informal description of a dilemma that they had experienced during their clinical practice. The results were as follows. The ethical dilemmas identified fell into four categories and were of 27 types. Those most frequently experienced (...) were ‘family giving up on a patient because he or she could not be cured’, and ‘not telling the truth to the patient’. The Korean Nurses’ Code of Ethics was applied, in particular the preamble, and the third, fourth, seventh and tenth clauses. The most common rule of ethics and principle applied in these nurses’ ethical decision making were veracity and nonmaleficence. With regard to the moral reasoning process, the primary concern was the welfare of the patients. These students were equipped with the ability to exercise critical and reflective thought when they experienced ethical dilemmas. (shrink)

ObjectivePrevious research has shown that adolescents in single-mother households are at heightened risk for adjustment problems. However, limited studies have investigated the mechanisms leading to adolescent problem behaviors in single-mother households. To address this research gap, this study applied the Family Stress Model to examine how single mothers’ material hardship is linked to adolescent problem behaviors, focusing on the mediating roles of mothers’ depression and mother-adolescent closeness. The moderating role of adolescent school connectedness in the relationships between mother-adolescent closeness and (...) school connectedness and between mothers’ depression and school connectedness was also investigated.Materials and methodsThe study analyzed data from 1,384 adolescents and their single mothers who participated in the Fragile Families and Child Wellbeing Study at Wave 6. The associations between study variables were analyzed using structural equation modeling by decomposing the direct, indirect, and total effects of material hardship on adolescent problem behaviors. School connectedness’s interactions with mother-adolescent closeness and mothers’ depression were also examined.ResultsResults showed a significant indirect relationship between material hardship and adolescent problem behaviors through sequential mediation of mothers’ depression and mother-adolescent closeness. Mothers’ depression also significantly mediated the relationship between material hardship and problem behaviors. Lastly, school connectedness moderated the relationship between mother-adolescent closeness and adolescents’ internalizing behaviors. The association between mother-adolescent closeness and adolescents’ internalizing behavior was weaker for adolescents with higher levels of school connectedness.ConclusionThe results indicate the important indirect effect of economic strain on adolescents’ problems behaviors in single-mother households, which has been less emphasized compared to the effects in earlier childhood. High rates of material hardship and adolescent problem behaviors in single-mother families call for multifaceted interventions focusing on family processes and protective factors, including school environment.

The present research seeks to utilize Implicit Theories of Intelligence and Achievement Goal Theory to understand students’ intrinsic motivation and academic performance in mathematics in Singapore. 1,201 lower-progress stream students, ages ranged from 13 to 17 years, from 17 secondary schools in Singapore took part in the study. Using structural equation modeling, results confirmed hypotheses that incremental mindset predicted mastery-approach goals and, in turn, predicted intrinsic motivation and mathematics performance. Entity mindset predicted performance-approach and performance-avoidance goals. Performance-approach goal was positively (...) linked to intrinsic motivation and mathematics performance; performance-avoidance goal, however, negatively predicted intrinsic motivation and mathematics performance. The model accounted for 35.9% of variance in intrinsic motivation and 13.8% in mathematics performance. These findings suggest that intrinsic motivation toward mathematics and achievement scores might be enhanced through interventions that focus on incremental mindset and mastery-approach goal. In addition, performance-approach goal may enhance intrinsic motivation and achievement as well, but to a lesser extent. Finally, the study adds to the literature done in the Asian context and lends support to the contention that culture may affect students’ mindsets and adoption of achievement goals, and their associated impact on motivation and achievement outcomes.

Although healthcare workers play a crucial role in helping curb the hazardous health impact of coronavirus disease 2019, their lives and major functioning have been greatly affected by the pandemic. This study examined the effects of the COVID-19 pandemic on the quality of life of Malaysian healthcare workers and its predictive factors. An online sample of 389 university-based healthcare workers completed questionnaires on demographics, clinical features, COVID-19-related stressors, psychological experiences, and perceived social support after the movement lockdown was lifted. All (...) domains of QoL were within the norms of the general population except for social relationship QoL, which was lower than the norm. Multiple linear regression analysis indicated that COVID-19-related stressors and psychological sequelae predicted lower QoL. Conversely, greater perceived social support from friends and significant others predicted higher QoL. Clinical and demographic characteristics predicted QoL to a lesser extent: A history of pre-existing medical illness was associated only with lower physical health QoL, whereas older age and being single, divorced, or widowed were only predictive of higher environmental QoL. Efforts to enhance QoL among healthcare workers in response to the pandemic should focus on mitigating COVID-19-related stressors and psychological sequelae and facilitating social support. (shrink)

This paper investigates the concept of missio Dei at Willingen and beyond, and identifies its most remarkable feature which regards God as the initiator and subject of mission, thereby redefining missio ecclesiae with three striking characteristics: first, all places of the world including both the immediate neighborhood and the uttermost parts of the earths; second, all spheres of life such as society, politics, economy and culture; and finally, all events of the time such as catastrophes in the history.In so doing, (...) this paper clearly discovers that missio Dei is here approached primarily in a differentiation from or a sharp contrast to missio ecclesiae from the start, and that, for that reason, the concept of missio Dei at Willingen and beyond has not been fully trinitarian, though it often mentions the triune God. And it also discovers that it goes further either toward an emphasis on culture on the one hand, or toward that on the world on the other hand.Such being the case, this paper suggests that it is necessary to consider the implications of the doctrine of the Trinity for mission more fully to reconfigure the concept of missio Dei. Due to some limits, this paper does not deal with this issue full-fledgedly, but intends to suggest a couple of guidelines for doing so. First, we need to approach missio Dei quite differently, that is, primarily not in relation to missio ecclesiae but in relation to processio Dei, that is, the procession of the triune God. Second, noting that, since the early church, missio Dei has been understood primarily in relation to processio Dei, we need to keep in mind that we could not discuss missio more fully without dealing with processio, and vice versa. If we have these two guidelines in mind, the concept of missio Dei would be much more abundant and fruitful. Further studies on some particular implications of the doctrine of the Trinity for mission need to be done in missiology and also theology in general in the near future. (shrink)

This paper examines the theoretical background and actual behavior in a gaming tournament with endogenous timing where a person has more incentive, structure, and time to form a strategy. The baseline treatment suggests that subgame perfection is a reasonable predictor of behavior –- subjects made 170 of 208 theoretically predicted choices of best actions, with the majority of mistakes made in timing choices by the players who did not survive the cut to the second round. Four sensitivity treatments established that (...) the design feature that lead to more predictable behavior was time to think –- 745 of 960 correctly predicted decisions with more time versus 595 of 960 with less time. A random effects Probit model suggests that the key design feature that closed the gap between predicted and observed behavior was not necessarily the non-linear payoffs created by the tournament design, but rather that the key was providing people with more time to think about their strategy.

The main purpose of this study was to validate a scale to examine the moral sensitivity of Korean nurses. A pre-existing scale, the Moral Sensitivity Questionnaire (MSQ), developed by Lützén, was used after deletion of three items. The reliability and validity of the scale were examined by using Cronbach’s alpha and factor analysis, respectively. According to the results, reliability of the scale was adequate but its construct validity was not fully supported. Through discussion on evidence of validity, five subconstructs emerged. (...) In particular, unlike the factor structure of the MSQ, two subconstructs, patient-oriented care and professional responsibility, were newly extracted. It was assumed that the other three MSQ subconstructs, conflict, meaning and benevolence (expressed as nurses being ethically good), would not be sensitive to cultural background. Given these findings, interpretations about the meaning of moral sensitivity of Korean nurses are discussed. (shrink)

Drawing upon Hannah Arendt's and Carl Schmitt's theories on the relationship between nomos and boundary, this paper revisits how constitutionalism and political power are reconciled as constitutional ordering. It first analyzes constitutionalism in the light of political modernity. Indicating that political power grounded by constitutions is omnipotent, complementing and completing constitutionalism, the paper contends that an omnipotent constitutional ordering is anything but an unleashed Leviathan. It is argued that constitutional omnipotence is framed and thus constrained by a constitutional nomos, the (...) matrix of which is a dual delimitation of boundaries, generational, and jurisdictional.

This article explains the attempts of nurses to practice humanistic, holistic care in line with their professionalizing strategy. Ideally, the intention of nurses is to broaden their concerns beyond the physiological needs of patients, thereby circumventing biomedical control over their work. However, the author argues that resource constraints, and the coalescing of biomedical and managerial definitions of patients, suggest that holistic notions of care are subjected to a new form of calculus and normalizing technology. Critically, nurses are more preoccupied with (...) the day-to-day struggle to free up resources for healthcare, in particular bed spaces, and to pre-empt the problem of bed blocking. Such work suggests that the ‘emptying of beds’ is not just a symbol of accomplishment for nursing work. From the governmentality theory of Foucault, the administration of ‘beds’ has become part of the managerial power/knowledge discourse and an instrument for making nurses toe the financial bottom-line.

Purpose: The purpose of this study was to verify the long-term effect of adverse childhood experiences, school disengagement, and the reasons for leaving school on adolescent delinquency while adjusting for sex.Methods: Data were collected from 663 teenagers [male 368, female 295; mean age = 16.81 ; age range = 13–19 years] through a Longitudinal Survey and Support Plan for Dropouts.Results: Multivariate latent growth modeling demonstrated that ACEs and school disengagement are positively associated with delinquency and the mediating effect of school (...) disengagement on association between ACEs and delinquency was verified. Teenagers who quit school for personal reasons reported fewer instances of delinquent behavior than adolescents who left because of school reasons.Conclusion: This study suggests that researchers and teachers need to consider ACEs and school disengagement as a warning index for delinquency with school dropout. In addition, the reason for leaving school should be considered to clarify the effect of school dropout on delinquency in adolescents who dropout. (shrink)

PurposeThis study aimed to examine the long-term association between social activity, physical function decline and cognitive function, as well as verify the long-term mediating effect of physical function decline on the relationship between social activity and cognitive function.MethodsData from the Korean Longitudinal Study of Aging that was collected over 10 years was analyzed. The sample included 10,240 adults aged 45–93 years. Multivariate latent growth modeling was applied to verify the long-term effect of social activity and physical function on cognitive function.ResultsThe (...) results revealed that social activity had a positive impact on cognitive function and negative impact on physical function decline after controlling for age and education level. Additionally, physical function decline negatively influenced cognitive function. Finally, social activity indirectly affected cognitive function through physical function decline.ConclusionThe contribution of this study was to test the long-term effect social activity on physical and cognitive function.

It is often necessary and reasonable to justify preferences before reasoning from them. Moreover, justifying a preference ordering is reduced to justifying the criterion that produces the ordering. This paper builds on the well-known ASPIC+ formalism to develop a model that integrates justifying qualitative preferences with reasoning from the justified preferences. We first introduce a notion of preference criterion in order to model the way in which preferences are justified by an argumentation framework. We also adapt the notion of argumentation (...) theory to build a sequence of argumentation frameworks, in which an argumentation framework justifies preferences that are to underlie the next framework. That is, in our formalism, preferences become not only an input of an argumentation framework, but also an output of it. This kind of input-output process can be applied in the further steps of argumentation. We also explore some interesting properties of our formalism. (shrink)

In this paper, we devise a network that consists of argumentation schemes and critical questions that participants in debates can use to easily construct arguments that attack or support former arguments. As a prototype, we build a potential network of argumentation schemes and critical questions with a practical reasoning scheme at its center. The usefulness of a NASCQ in constructing and reconstructing complex arguments and in formal argumentation is also explored along with argumentation more broadly.

The bulletin board system (BBS) significantly changed the production and transmission of knowledge in China’s information technology (IT). Launched in 1991, Chinese FidoNet (CFido) provided a virtual space for hobbyists to explore technology-for-fun and aggregated many future Chinese digital entrepreneurs, enabling them to experiment with business models and pursue open-source software with Chinese characters. CFido’s short history (1991–1998) also encapsulates the fast-changing dynamic between knowledge and its social context. CFido participants first perceived the BBS as a utopian “pure land” where (...) grassroots intellectuals could develop software and digital technologies, free from outside interests and interventions. Yet the beginning of government control of cyberspace, the boom of the IT industry and e-commerce, and the transition from the dial-up BBS to the Internet led the CFidoers to diverging positions about amateurs and ultimately brought CFido to an end.

Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese learning English /r/-/l/ (...) categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players’ responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5 h across 5 days exhibited improvements in /r/-/l/ perception on par with 2–4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.

Storytelling is getting increasing attention as one of the effective strategies for revitalizing the local festivals and even regional economies. Yet, the mechanisms through how storytelling helps the success of local festivals are still relatively less known. Using the data from 322 individuals who participated in local festivals using storytelling, our results showed that local festival storytelling is positively related to tourists’ revisit intention. Furthermore, the positive relationship between local festival storytelling and tourists’ revisit intention was serially mediated by authenticity (...) and positive emotion. Theoretical and practical implications are discussed. (shrink)
