Paintings are in essence about visual features of varying significance from which differences in their market prices originate. Studies normally investigate derivative sources of painting price determinants, which is reasonably understandable because the appreciation of an image is quite subjective. This paper provides an operational solution to the quantification of paintings based on a new concept termed as “visual autocorrelation” of prices (VAP). Considering the current empirical framework of spatial and temporal autocorrelation of prices, and using data on the paintings of two abstract expressionist artists, empirical results support the coherence of the VAP concept. 相似文献
Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub-groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units. 相似文献
This study aims to identify the needs of early childhood educators regarding distance education during the COVID-19 pandemic. This basic qualitative research was carried out with a study group of 24 early childhood educators, all of whom were determined via a maximum variation sampling method. The study data were gathered via interviews conducted with the participants and analyzed through an inductive approach. The study findings showed that early childhood educators need to improve their technological competencies, have more interactive resources at their disposal, be able to take advantage of a user-friendly educational platform specifically designed for the early childhood period, be provided with the resources to serve families, and have support for their psychological well-being. Considering the essential role of teachers, which the COVID-19 pandemic has called to mind, it is of vital importance to meet the abovementioned needs so as to improve the quality of distance education in early childhood.
College students experience great stress due to many factors, such as an uncertain future, academic responsibilities, and pressures imposed by social communication. Many institutions of higher education are focusing on how to mediate stressful situations and increase the subjective well-being (SWB) of students to sustain a lifestyle focused on wellness. The online survey used for this study focused on testing an exploratory SWB model by implementing partial least squares structural equation modeling (PLS-SEM) techniques. The participants were 470 college-aged students enrolled in seven different institutions in six cities across China. Findings yielded a good model fit (the Standardized Root Mean Squared Residual [SRMR] = .054) with the validity of manifest variables, reliability of the latent variables (LVs), and overall SWB model indicating moderate predictiveness (GoF R2 = .476) by the LVs. Additionally, all of the direct path coefficients and indirect path coefficients that consisted of four partial mediators and one full mediator yielded statistically significant results via bootstrapping. Furthermore, path coefficients for utilization of emotion to life satisfaction for the cognitive exercise group were significantly higher than for the non-cognitive exercise group. The findings illustrated a good model fit for an exploratory SWB model that can predict an individual’s SWB, and cognitive and non-cognitive exercises had different effects on the individuals’ SWB. 相似文献
AbstractThe years 1989–91 saw tremendous changes in the political map of Eastern Europe. These changes have resulted in varying degrees of acquisition difficulties for Slavic and Eastern European language collections in Western libraries. The following is an early assessment of the difficulties and the resultant damage done to Slavic collections in the West. Preliminary results show that, on the whole, book receipts are down considerably, prices are up considerably, and inconsistency is the only consistency. The data discussed here were gathered by means of a survey of certain aspects of Slavic1 acquisitions. These data are supplemented throughout by qualitative material gleaned from comments made by vendors and librarians at the 1993 Slavic Librarians' Workshop held at Urbana, Illinois. 相似文献
