  • This study was carried out to examine the development of physical knowledge in children. Eighty children aged 3- to 11-year-old and 16 adults were participated in this study. Participants' knowledge about failing, sliding and sinking/floating objects was investigated to understand what kind of knowledge they had, whether their knowledge was organized as theory and what was the nature of the developmental change in physical knowledge. Results showed that, for falling object task children of all age had correct knowledge about object's falling phenomena. However, there were age differences in children's understanding of the cause of object's falling. As the children's age decreased, the frequency of explanation referring to the absence of supper rather than the gravity as the cause of falling phenomena increased. For the sliding object task, children of all age could predict the motion of sliding object correctly. But only a few 9- and 11-year-old children could understand the effect of object weight and relations between gravity, frictional force and their interactions. Children under age 7 showed no evidence of possessing these knowledge. For sinking or floating object task, children of all age and even adults showed difficulties in understanding the sinking or float phenomena per se. For the cause of these phenomena although a few 9- and 11-year-old children referred to buoyancy as the cause, they had no correct knowledge about the buoyancy. This was also true for the adults. As a conclusion, the results of this study suggested that, not 3, but as young as 5-year-old children's physical knowledge exited as a form of naive theory in terms of their use as a causal devise in explaining the cause of object motion. However, even the theory of 9- and 11-year-old children was lack of the abstractness and coherence, which were also important characteristics of a theory. Finally, developmental change in physical knowledge proceeded toward more frequent and consistent use of physical knowledge as causal device and more abstract and coherently organized theory.

  • The purpose of this study is to analyze the effects of strategic roles of IS and characteristics of ISP on the performance of ISP in view of contingency theory. In particular, this study is to find out whether there is a fit between two contingent variables. To evaluate the effects of two independent variables on the dependent variable empirically, a field research method using questionnaires with depth interview was employed. Findings of the field study are as follows: First, the main effect of strategic roles of IS on performance of ISP is found to be significant. This implies that the higher the strategic importance of IS, the better the performance of ISP expected. Second, the effect of characteristics of ISP on the dependent variable is also found to be significant. Organizations which recognize IT as an important competitive weapon for their business, and adopt Technological and Organizational approaches in ISP, have shown to obtain excellent results. Third, the interaction effect of two contingent variables is not found. There is no evidence for a fit between the strategic roles of IS and the characteristics of ISP. This shows that the differences of ISP performance are to be explained by only independent effect of two contingent variables.

  • The main purposes of this study are (1) to investigate the extent and level of corporate social responsibility (CSR) practices of the hotel in Thailand, (2) to test the different level of CSR practices of the hotel between CSR-in-process and CSR-after-process, and (3) to examine the effect of CSR practices on hotel's performance measured by balanced scorecard (BSC). This study employs survey data collected from 402 owners and executives of hotels in Thailand. Descriptive analysis, paired sample t-test, correlation matrix, and multiple regression were used to analyze the data from the mailed questionnaire. The results show that both CSR-in-process and CSR-after-process practices of hotels were at a high level. However, the level of CSR-in-process practice of hotels was significantly higher than CSR-after-process practice. Moreover, the study found the positive effect of both CSR-in-process and CSR-after-process practices on hotel performance measured by BSC. The results of sensitivity analysis also show the positive effect of CSR-in-process and CSR-after-process practices on each of all six perspectives of BSC. The findings of this study can point to the reasonable reason why hotels should implement CSR practices into their business strategies. In addition, the study demonstrates that stakeholder theory can explain the effect of CSR practices on corporate performance.

  • The purpose of this paper is to explore how the country-of-origin image mediates the effect of national stereotypes along two dimensions of perceived competence and warmth, on consumers' consumption behaviors, especially in today's environment, the capricious COVID-19 and the deepening and expanding "The Belt and Road" initiative. Research design, data, and methodology: After collecting 1500 primary data from twelve countries along the 21st - Century Maritime Silk Road, this paper conducts ANOVA and SEM in SPSS25.0 and AMOS 24.0 separately to analyze measurements, structural models, and hypotheses via using 1277 final samples. The mediation results illustrate the asymmetric dominance of the two dimensions of national stereotypes, indicating that the country-of-origin image shows the complementary mediation in the effect of perceived competence on purchase intention; whereas, the country-of-origin image holds the indirect-only mediation in the impact of perceived warmth on purchase intention. The results of the moderation show that the effect of country-of-origin image on purchase intention is more significant for consumers who perceive COVID-19 in China to be of lesser severity than those who believe it to be of higher severity. Based on the paper's results, some implications for practice and theory are highlighted.

  • Objectives: Examine the difference of Chosun acupuncture from the acupuncture in Myung, Chung Dynasty Method: This paper examines the acupuncture mentioned in the classic of Introduction to Medicine For this, the special traits of Introduction to Medicine acupuncture was analyzed. Secondly, the research on the contents of Introduction to Medicine acupuncture quoted in the classic of Essential Rhymes of Acupuncture and Moxibustion, Treasured Mirror of Eastern Medicine, and Experimental Prescriptions of Acupuncture and Moxibustion was carried out. Result: Introduction to Medicine put much importance on "method of acupuncture following the five circuits and six qi" (子午流注針法) and Song of Acupuncture and Moxibustion through comparing "eight methods of acupuncture following the five circuits and six qi" (子午八法) and "scattered needling method". The doctors in Chosun Dynasty, howevery, did not adopt this theory with their own standards on acupuncture. On the contrary, they put more importance on the inquiry of historical evidence on river point and extraordinary points. Conclusion: The acupuncture studies of Chosun Dynasty had already formed its own standards on the medical theories, and its direction to which it was headed was different from that of the Myung, and Chung Dynasty in China.

  • In general, every welfare state is to be productive. If not, the welfare state itself cannot be sustainable because resource for the development of welfare only comes from a sound level of economic development However, how to mix welfare and production differs from country to country. This article tackles this phenomenon as a starting point. Granted, contemporary studies of comparative welfare state often starts from the theory of welfare regime which has been suggested by Esping-Andersen. This article also regards the framework as an analytic tool to elaborate upon the concept of productive welfare and to categorize different types of conception of productive welfare. In liberal regime, the concept is so narrowly interpreted that they emphasize micro-efficiency of specific welfare programs. On the contrary, the other two regime types recognize the concept of productive welfare as relatively wide. Therefore, conservative and social democratic regimes underscore macro-efficiency of the welfare state as a whole. Empirical analyses of this article explores each regime's success and failure in terms of achieving fundamental goals of the welfare state, i.e. economic development and enhancement of equality. A series of evidence show that liberal regime fails in achieving both goals, while the other two regimes seem to be relatively successful. In conclusion, it may be pointed out that current tendency of neo-liberalism and anti-welfarism in Korea should be overcome, which must be the prime task of social welfare academia of this country.

  • This study aims to find out whether political parties apply financial reports under PSAK (Statement of Financial Accounting Standards) No. 45. The Stewardship Theory provides the analytical framework. The objects in this study were 16 Yogyakarta City Political Parties in the Special Region of Yogyakarta, with the total number of 64 respondents. The application for processing data in this study used SPSS 22 version. Based on the results of analyzing data, H1, which had a sig (2-tailed) value of 0.026 <0.05, then H0, stating that there was an influence of the statement of financial position on the implementation of PSAK, was rejected. H2 had a sig (2-tailed) value of 0.116> 0.05, so that H0, stating that there was no significant effect of the activity report on the implementation of PSAK, was accepted. H3 had a sig (2-tailed) value of 0.027 <0.05, meaning that it rejected H0, which stated that there was a significant effect of the cash flow statement on the implementation of PSAK. Furthermore, H4 had a sig (2-tailed) value of 0.744> 0.05, indicating that H0 was accepted, stating that there was a significant effect of notes to the financial statements on the implementation of PSAK.

  • The recently introduced index Ratio Of Torsion (ROT) quantifies the base shear amplification due to torsional effects on shear cantilever types of building structures. In this work, a theoretical proof based on the theory of elasticity is provided, depicting that the ratio of torsion (ROT) is independent of the forces acting on the structure, although its definition stems from the shear forces. This is a particular attribute of other design and evaluation criteria against torsion such as center of rigidity and center of strength. In the case of ROT, this evidence could be considered as inconsistent, as ROT is a function solely of the forces acting on structural members, nevertheless it is proven to be independent of them. As ROT is the amplification of the shear forces due to in-plan irregularities, this work depicts that this increase of internal shear forces rely only on the structural topology. Moreover, a numerical verification of this theoretical finding was accomplished, using linear statistics interpretation and nonlinear neural networks simulation for an adequate database of structures.

  • The purpose of this paper is to examine some of the theories concerning socioaffective strategies, to analyze the dialogues of the students negotiating for meaning of a reading material and to suggest some implications of socioaffective strategies for teaching reading. The examination of the theories - the interaction hypothesis and the sociocultural theory - suggest that the use of socioaffective strategies facilitates more effective understanding of information that is to be found. distributed, and taken in among the participants. The discourse analyses of the students' interaction in a Korean college English reading class show ample evidence of the use of socioaffective strategies that helped them understand the meaning of a text. However, the analyses show that the strategies are mostly used to ask questions concerning the meaning of clauses. Only few analytical questions are raised for some structural and pragmatical features in the text which are crucial to the understanding of its meaning. Imbalance also exists in the types of the questions used by the participants. The analyses indicate that, instead of negotiating more interactively, the students tend to rely upon a more advanced student when they face difficult English sentences. Therefore as a conclusion this paper emphasizes the importance of teaching socioaffective strategies to help students to help themselves to become more cooperative, independent and analytical in reading English texts.

  • Purpose: The main purpose of this study is to find out the impact of ownership structure on firm performance in the pharmaceutical and chemical industry of Bangladesh. Research design, data and methodology: The study has been conducted on 28 listed pharmaceutical and chemical companies from 2012 to 2020. Return on Assets (ROA) and Tobin's Q are selected as indicators of internal and market performance of the firms respectively whereas institutional ownership, directors' ownership and foreign ownership are selected as proxies of ownership structure. Panel analysis using random effects, lag method and time dummy method is used to analyse the relationship. Results: The study has found the existence of highly concentrated directors' ownership, a low percentage of institutional ownership and a very insignificant proportion of foreign ownership in the industry. The regression results show that directors' ownership has a positive and significant impact on firm performance, supporting the concept of agency theory. The study has also found a positive and significant impact of foreign ownership on firm performance. Unfortunately, the impact of institutional ownership is found to be insignificant. Conclusions: Directors' ownership and foreign ownership decreases agency cost that ultimately increases firm performance. However, the role of institutional investors is not significant enough to improve firm performance. It is suggested that institutional investors should be more active and involved in monitoring the activities of the organisations to improve performance.
