Drawing on the impression management theory, this study examined the effect of online media platforms, social network sites (SNSs) versus non-SNSs, on the intention to join a cause. The online experimental study discovered that the SNS was more effective in increasing the intention to join a cause than the non-SNS. The findings also demonstrated the mediating role of the perceived visibility of joining the cause and the moderating role of public self-consciousness on this effect. Further, self-cause image congruence positively influenced the intention to join the cause, while it did not moderate the effect of online media platforms. 相似文献
We explored the experiences and emotions women expressed about having a blood clot, including revelations about family members' decision to avoid disclosing inherited risk for clotting. We do this through analysis of in-depth life reflection interviews (N = 20) of women who experienced a first venous blood clot between the ages of 18 and 50 years. Selective coding reduced the data to an overarching story associated with thrombosis survivorship and loss across multiple life domains. The themes identified include participant revelations about living in the shadow of genetic susceptibility for thrombosis. Participants manage changes associated with lingering health effects, and daily routines for work and life, adapting their lives to manage coagulability. A second theme reveals the fallout linked to the severity of thrombosis encompassed in haunting psychological scenarios, persistent emotional concerns, and social discrimination. Participants assumed responsibility to disclose inherited risk, with the women expressing empowerment in knowing risks and acknowledging possible genetic testing mistakes. The overarching perspective was one of hope through proactive actions in occupational, recreational, and relational realms. We offer our findings as a theoretical depiction of thrombosis survivor identity and the need for public health and clinical communication to support disclosing family history for clotting. 相似文献
In the present study, we describe a participating student’s (Carol’s) distributive partitioning scheme and operations along with Steffe’s and his colleagues’ studies about children’s constructions of fraction knowledge as a particular model of mathematical learning. Analysis of Carol’s mathematical behaviors indicates that an operationally common mathematical behavior (distributive partitioning operation) was revealed in various mathematical problem situations such as fraction multiplication, fraction division, and multiplicative transformation between fractional quantities. It both provides a rationale for why becoming versed in one mathematical subject could facilitate working with another mathematical subject and also implies the necessity of describing and defining students’ mathematical behaviors from an operational view of knowledge, which might lead to building foundations of a substantial cognitive map for students’ mathematical development.
This article presents a meta‐analysis of experimental and quasi‐experimental studies in which intermediate and secondary students with learning disabilities were taught science content through the use of graphic organizers (GOs). Following an exhaustive search for studies meeting specified selection criteria, 23 standardized mean effect sizes were extracted from six articles involving 271 participants in grades 6 through 12. Findings included that, across immediate posttest and maintenance conditions, the use of GOs was associated with increased vocabulary knowledge and factual comprehension measured by researcher‐generated multiple‐choice tests in science. Conclusions, implications for future research, and practical recommendations are presented. 相似文献
The Theory of Planned Behavior (TpB) measures the effect that individuals' behavioral belief normative belief and control beliefs have on their intentions to perform a specific behavior The purpose of this study was to examine: (a) whether the TpB could predict physical educators' intentions and (b) whether physical educators' intentions and control beliefs could predict their self-reported teaching behavior. A sample of 220 physical educators completed the questionnaire. Stepwise multiple regression analysis revealed that the TpB significantly predicted physical educators' intentions, F(3, 216) = 57.21, p < .01. However, only intention was a significant predictor of physical educators'self-reported behavior in teaching students with disabilities, F(2, 123) = 34.04, p < .01. 相似文献
This article reports research on New York‐based Korean artists' dynamic processes of identity‐shaping and the implications that these processes have for art education. The study uses postcolonial theories that illuminate the dialectical process of hybrid cultural production in the global dimension. The artists' identities narrated elucidate the recognition of difference with others; this identification emerges as the artists simultaneously escape from and discover their Korean identities. The artists' childhood experiences and memories work as reflective thinking in their different context, and because of their search for an individual identity, Korean culture is an important factor in their art making. When their identity formation and practice are in constant negotiation with difference, this results in learning and translating from others. They assume an ‘open universalism’ necessary to communicate at an international level, and as a consequence these artists' identity formation always involves the process of a doubling and dividing of reflections of existing Korean identities as well as the building of new ones. In this dualistic state, the artists' multiple identities remain heterogeneous, composed of contradictory factors that are revealed in the artists' hybrid artworks. 相似文献
Globalization increasingly calls for comparing educational policies across countries. In this study, we assemble and analyze academic journal publications of the past decade in order to shape education policy research within an Asia-Pacific context. After examining Asia-Pacific research publication data from the Web of Science, we find a few stylized facts: (1) increasing research collaboration, (2) growing policy evaluation research, (3) swelling empirical research with quantitative methodology and (4) growing attention to higher education. Moreover, education stakeholders show exclusive interest on globalization, private tutoring, and language education policies within and across countries. Finally, we find a significant difference in research impact and diffusion between Asia-Pacific and American education policy studies. Further, we examine what determines research impact and diffusion. Our results indicate that research collaboration, national context, publication year and issue, policy area, and research methodology are significantly associated with publication citations. Based on the findings, we suggest useful implications for future directions on education policy research in an Asia-Pacific context. 相似文献
This article discusses how supply chain information capabilities are instrumental to achieve performance outcomes. We identify critical components of supply chain information capabilities in terms of inter-organizational information system capacity and inter-organizational relational competency. In view of the high degree of industry concentration in Korea, this article presents and tests a research model using a sample of Korean steel suppliers. Empirical tests are conducted using the structural equation modeling, PLS (partial least squares). The results of this study suggest that Korean manufacturing (e.g., automobile, shipbuilding, construction, and mobile industries) are heavily influenced by the competitiveness of the steel industry in terms of supply chain information capabilities and performance outcomes—supply chain-level (i.e., supply chain flexibility) and firm-level performance outcomes (i.e., customer responsiveness and cost reductions). Future research may extend the findings of this study in other country contexts to accomplish both customer responsiveness and cost reductions through supply chain information capabilities. 相似文献
This study investigated how cultural differences between Korea and the United States in attitudinal and normative components affect individuals’ explanation of their intentions to lie or tell the truth. Study 1 examined individuals’ intentions to base their lying or truth-telling tendencies on attitude-related reasons (i.e., attitudinal reasons) and subjective norm-related reasons (i.e., normative reasons). Study 2 examined individuals’ evaluation of a person who used attitudinal reasons or normative reasons to explain his/her behaviors of lying or truth-telling. The results showed that neither culture used one type of reason consistently across different behaviors. Instead, the types of behaviors influenced the way attitudinal and normative components were related to behavioral intentions. The attitudinal component was important for individuals’ explanations of their attitudinal reasons to lie and to tell the truth and that the normative component was important for individuals’ explanations of their normative reasons to lie. However, both the attitudinal and normative components were important for individuals’ explanations of their normative reasons to tell the truth. Cross-culturally, Koreans were more likely to use normative reasons when they had to explain why they intended to lie for a friend, whereas Americans were more likely to use normative reasons when they had to explain why they intended to tell the truth. In addition, Koreans and Americans had different preferences for each reason type depending on the type of behavior probably because Koreans, as compared to Americans, tend to view lying for a friend less negatively. 相似文献
Interest in single-cell analysis has increased because it allows to understand cell metabolism and characterize disease states, cellular adaptation to environmental changes, cell cycles, etc. Here, the authors propose a device to electrically trap and lyse single-bacterial cells in an array format for high-throughput single-cell analysis. The applied electric field is highly deformed and concentrated toward the inside of the microwell structures patterned on the planar electrode. This configuration effectively generates dielectrophoretic force to attract a single cell per well. The microwell has a comparable size to the target bacterial cell making it possible to trap single cells by physically excluding additional cells. Inducing highly concentrated electric potential on the cell membrane can also effectively lyse the trapped single-bacterial cells. The feasibility of the authors' approach was demonstrated by trapping and lysing Escherichia coli cells at the single-cell level. The present microwell array can be used as a basic tool for individual bacterial cell analysis. 相似文献
