Abstract We introduce an infinite variant of hypersurface support for finite-dimensional, noncommutative complete intersections. We show that hypersurface support defines a support theory for the big singularity category $\operatorname {Sing}(R)$ , and that the support of an object in $\operatorname {Sing}(R)$ vanishes if and only if the object itself vanishes. Our work is inspired by Avramov and Buchweitz’ support theory for (commutative) local complete intersections. In the companion piece [27], we employ hypersurface support for infinite-dimensional modules, and the results of the present paper, to classify thick ideals in stable categories for a number of families of finite-dimensional Hopf algebras.

A methodology of expert analysis of the market of alternative corporate information systems (CIS) is proposed in order to choose the platform for creating a CIS that fully meets the requirements of a particular defence company. The proposed methodology is based on a set of adapted methods of the decision support theory applied to the problems of multi-criteria collective choice of alternatives.

Abstract Along with the groundbreaking development of communication technology, caregivers have migrated to online platforms to seek help. Social support theory, including main effect and moderation effect models, has provided a framework to understand the association among caregivers’ stress, support from others, and their well-being. Despite the prevalence of online use for seeking help among caregivers, studies on the use of online social support within the context of caregivers’ stressors and well-being are still underdeveloped. Guided by social support theory, this study aimed to examine the association of online social support (OnSS) and caregivers’ mental health (MH) as compared with offline social support (OffSS). A subsample of caregivers of persons with Alzheimer’s from the Health Information National Trends Survey from 2017-2018 was selected (n=264). For an analysis, ordered logistic regression models with Jackknife estimation methods were applied using Stata 15.1SE. First, OffSS had a positive direct association with caregivers’ MH (Odds Ratio=12.48, p<.05) while OnSS did not. Next, the moderation effect model analysis found that OffSS interacted with caregiving burden while OnSS interacted with life stressors. The MH of caregivers who are in less favorable situations, such as working part-time while caring for a person with Alzheimer’s, living with economic hardship, and having health problems, tended to be significantly affected by OnSS. Identifying the different roles of OnSS and OffSS for caregivers’ MH, the findings of this study call for more attention to developing novel strategies and sensitive approaches to support family caregivers, especially those who fall in underserved groups.

We develop a support theory for elementary supergroup schemes, over a field of positive characteristic p ⩾ 3 p\geqslant 3 , starting with a definition of a π \pi -point generalising cyclic shifted subgroups of Carlson for elementary abelian groups and π \pi -points of Friedlander and Pevtsova for finite group schemes. These are defined in terms of maps from the graded algebra k [ t , τ ] / ( t p − τ 2 ) k[t,\tau ]/(t^p-\tau ^2) , where t t has even degree and τ \tau has odd degree. The strength of the theory is demonstrated by classifying the parity change invariant localising subcategories of the stable module category of an elementary supergroup scheme.

Penelitian ini bertujuan untuk mengetahui apakah social support dan hardiness berkontribusi terhadap academic resilience pada mahasiswa yang mengerjakan skripsi di Kota Makassar. Penelitian ini menggunakan pendekatan kuantitatif dengan populasi mahasiswa semester akhir yang mengerjakan skripsi di Kota Makassar dan berusia 18-40 tahun. Sampel dalam penelitian ini berjumlah 360 responden. Alat ukur yang digunakan yaitu skala social support yang dibuat sendiri oleh peneliti berdasarkan pada teori social support oleh Sarafino & Smith, skala hardiness yang diadaptasi berdasarkan teori Benishek & Lopez, dan skala academic resilience berdasarkan teori Martin & Marsh  yang dimodifikasi oleh peneliti. Data dianalisis menggunakan teknik regresi berganda dengan bantuan aplikasi SPSS 20. Hasil analisis menunjukkan bahwa social support dan hardiness berkontribusi terhadap academic resilience sebanyak 47%. Sedangkan secara terpisah, penelitian ini menunjukkan bahwa social support berkontribusi terhadap academic resilience sebanyak 33.7%, dan hardiness berkontribusi terhadap academic resilience sebanyak 13.2%. Hasil analisis tersebut menunjukkan bahwa Ha diterima dan Ho ditolak. Dengan demikian terdapat kontribusi social support dan hardiness terhadap academic resilience pada mahasiswa yang mengerjakan skripsi di Kota Makassar. This study aims to determine whether social support and hardiness contribute to academic resilience in students working on thesis in Makassar City. This study uses a quantitative approach with a population of final semester students working on thesis in Makassar City and aged 18-40 years. The sample in this study amounted to 360 respondents. The measuring instrument used is the social support scale which was made by the researcher based on the social support theory by Sarafino & Smith, the hardiness scale adapted based on the Benishek & Lopez theory, and the academic resilience scale based on the Martin & Marsh theory modified by the researcher. The data were analyzed using multiple regression techniques with the help of the SPSS 20 application. The results of the analysis showed that social support and hardiness contributed to academic resilience as much as 47%. Meanwhile, separately, this study shows that social support contributes to academic resilience as much as 33.7%, and hardiness contributes to academic resilience as much as 13.2%. The results of the analysis show that Ha is accepted and Ho is rejected. Thus, there is a contribution of social support and hardiness to academic resilience for students working on thesis in Makassar City.

When people are asked to estimate the probability of an event occurring, they sometimes make different subjective probability (SP) judgments for different descriptions of the same event. This implies the evidence or support recruited to make SPs is based on the descriptions of the events (hypotheses) instead of the events themselves, as captured by Tversky and Koehler's (1994) support theory. However, is the support assigned to a hypothesis invariant, as support theory assumes? Here, across two studies where participants were asked to estimate the probability that an event would occur, we show that the support people recruit about the target hypothesis also depends on the other hypotheses under consideration. The first study shows that the presence of a distractor---a hypothesis objectively dominated by the target hypothesis---boosts the SP assigned to the target hypothesis. The second study shows that the presence of a resembler---a hypothesis that is objectively similar to the target hypothesis---detracts more from the SP assigned to the target hypothesis than the competing hypothesis. These context effects invalidate the regularity and the strong independence assumptions of support theory and more generally suggest a similar process that drives the construction of preference also underlies belief.

The COVID-19 pandemic forced unprecedented changes upon journalists in the United States as they attempted to cover the story while adhering to the same stay-at-home orders as the rest of the public. This study used organizational support theory to investigate the stress associated with the logistics of coverage early in the pandemic and how perceived organizational support played a role in either alleviating or adding to that stress. In total, 222 journalists responded to a survey sent out during the first few weeks of the stay-at-home orders issued across the United States. Results revealed varying degrees of logistical support provided by news organizations with nearly one quarter receiving no supplies, technology, or extra training at all. Greater perceived organizational support was associated with lower levels of stress and higher levels of work commitment. Female journalists and those who were younger and less experienced felt significantly more stress associated with pandemic coverage.

In the hospitality sector, it is often believed that giving more power to customers (e.g., “the customer is king”) would enhance the service quality, customer satisfaction, and organizational performance. However, it can cause a backlash by excessively elevating the level of the customers’ perceived power, which could result in their power abuse against the employees. Based on the organizational support theory, this research argues that balancing the level of power between the customers and the employees (vs. shifting the power to the customers) can be more effective for improving the perceptions of both the current and the potential employees. The argument is empirically supported by the findings from three studies, which showed that adopting a power-balancing message positively affects the current employees’ perceived organizational support and motivates them to feel obliged to give back to the organization and also potential job applicants’ organizational attraction and the job pursuit intention.

PurposeThe purpose is to understand how affective events employees experience at work, and emotions those events elicit, influence within-person fluctuations in perceived organizational support (POS). The authors explore the possibility of socioemotional needs as a boundary condition of the effects. They integrate affective events theory with organizational support theory to develop their arguments.Design/methodology/approachUsing a diary study method, 55 working adults responded to three surveys per day for ten days (876 total datapoints).FindingsThe results suggest POS fluctuates daily. Furthermore, workplace affective events are significantly related to discrete emotions (happiness and anger), which are significantly related to fluctuations in POS. Indirect effects were generally stronger when socioemotional needs were high compared to low, though the moderation was not statistically significant.Research limitations/implicationsThe authors extend organizational support theory by integrating affective events theory; they highlight the role of affective events and transient emotion in relation to momentary changes in POS and explore socioemotional needs as a moderator of those relationships.Practical implicationsOrganizations can be mindful of employees' daily experiences when considering how to foster POS; minimizing negative affective events and maximizing supportive affective events may enhance POS.Originality/valueThis study is the first to consider predictors of short-term fluctuations in POS. Moreover, the authors integrate affective events and discrete emotions to consider the role of affect in organizational support theory.
