A japán társadalmi klaszterek szerepe és kihasználásának lehetőségei a versenyképesség megtartásában = The Role of Clusters in Japan’s Competitiveness

Az amerikai történelemben a paradigmaváltások meglehetősen nagyszabású és alapvető hatásokkal jártak, míg Japánban mintha hosszú távon is a Tudományos vezetés (gyártás-orientált) paradigmájánál maradtak volna, mely aztán módosult valamennyit a többi paradigma megjelenésének hatására. A tanulmány ebből az elméleti megállapításból kiindulva vizsgálja meg mind szakirodalmi alapon, mind egy kérdőíves kutatás segítségével, a japán társadalom „reakcióidejét”: attitűdjeit a változással, az alkalmazkodással szemben. Alapfeltételezése, hogy a tartós versenyképesség fenntartásához elengedhetetlen a külső körülményekhez való folyamatos alkalmazkodás, ami időről időre a múlt gyakorlatainak megkérdőjelezését eredményezi. Rövid elemzésünk azon az előfeltevésen alapult, hogy egy vagy több, a számát és / vagy társadalmi befolyását tekintve jelentős társadalmi csoport továbbra is erősen támogatja a hagyományos japán vezetési gyakorlatot. A hipotézist sikeresen bebizonyítottuk: a hagyományos menedzsmentet szignifikánsan támogatta két olyan klaszter, melyek száma jelentősen meghaladta a panel fennmaradó részét és amelyek nagyobb fokú társadalmi befolyást is képviseltek. Megállapítottuk, hogy a régi rendszert valószínűleg azok a rangidős japán férfiak támogatják, akik állandó dolgozóként vagy vezetőként dolgoznak meglehetősen nagy vállalatoknál, hosszú távú foglalkoztatásban. Egy másik csoportot is azonosítottunk az előzővel szemben, mely fiatalabb tagokból áll, változatosabb és magasabb iskolai végzettség jellemzi. Még nem egyértelmű, hogy a második csoport tagjai életkoruk előrehaladtával betagozódnak majd a japán rendszerbe és vállalatokba, ahogy az a múltban is történt, vagy továbbra is küzdenek majd a hagyományos módszerek ellen. Mindenesetre célszerűnek látszik az eredmények alapján a kutatás továbbgondolása és magyarországi megvalósítása is, ami által a magyar gazdasági és kormányzati elit a versenyképesség szempontjából értékes információkhoz juthat, nevezetesen az elavultnak számító gyakorlatok beazonosításán és az ennek fennmaradásáért felelős csoportok leírásán keresztül. _________ In the American history, change between paradigms implied rather large-scale and deep effects, whereas the Japanese seem to keep the focus on the Scientific Management (or production-oriented) paradigm which was only party altered by the others (HR, etc.). Based on this affirmation, our study examines the reactivity of Japanese society both in a theoretical and in a practical sense. We assumed first that continuous adaptation to the external conditions is an essential element of long-term competitiveness, which implies the regular questioning of old management practices. We presumed that one or several group(s) of people is (are) still strongly supporting traditional Japanese management practices and they must be important in terms of number and/or social influence. We have found evidence for our hypothesis: two significantly supportive clusters which largely outnumbered the rest of the panel and represented a higher level of social influence as well. We stated that the old system is probably supported by senior Japanese males who work as regular (core) employees or managers in rather large companies and enjoy long-term employment. Another group was also identified as a contrast to the former one, with younger members, more diversity and a higher level of education. As they grow older, the second group may become socialized into the Japanese system as happened in the past, or continue to reject traditional methods. Based on our observations, it seems useful to broaden the focus of our research and carry out a similar study in Hungary as well. This will bring valuable information on competitiveness to the business and political elite, enabling them to identify inefficient old practices and to better target the groups responsible for maintaining those practices.

Are Democratizing Countries ‘Rewarded’ with Higher Levels of Foreign Aid?

The paper examines how flows of foreign aid have reacted to events of democratization in developing countries. Using a panel dataset of 136 aid receiving countries between 1980 and 2009, aid allocation regressions reveal that donors in general have tended to react to visible, major democratic transitions by increasing aid to the partner country, but no significant increases can be identified in case of countries introducing smaller democratic reforms. The increases in aid flows are not sustained over time, implying that donors do not provide long term support to nascent democracies. Also, democratizations in Sub-Saharan Africa do not seem to have been rewarded with higher levels of aid.

International stock portfolio selection and performance measures recognizing higher moments of return distributions

Since the seminal works of Markowitz (1952), Sharpe (1964), and Lintner (1965), numerous studies on portfolio selection and performance measure have been based upon the mean-variance framework. However, several researchers (e.g., Arditti (1967, and 1971), Samuelson (1970), and Rubinstein (1973)) argue that the higher moments cannot be neglected unless there is reason to believe that: (i) the asset returns are normally distributed and the investor's utility function is quadratic, or (ii) the empirical evidence demonstrates that higher moments are irrelevant to the investor's decision. Based on the same argument, this dissertation investigates the impact of higher moments of return distributions on three issues concerning the 14 international stock markets.^ First, the portfolio selection with skewness is determined using: the Polynomial Goal Programming in which investor preferences for skewness can be incorporated. The empirical findings suggest that the return distributions of international stock markets are not normally distributed, and that the incorporation of skewness into an investor's portfolio decision causes a major change in the construction of his optimal portfolio. The evidence also indicates that an investor will trade expected return of the portfolio for skewness. Moreover, when short sales are allowed, investors are better off as they attain higher expected return and skewness simultaneously.^ Second, the performance of international stock markets are evaluated using two types of performance measures: (i) the two-moment performance measures of Sharpe (1966), and Treynor (1965), and (ii) the higher-moment performance measures of Prakash and Bear (1986), and Stephens and Proffitt (1991). The empirical evidence indicates that higher moments of return distributions are significant and relevant to the investor's decision. Thus, the higher moment performance measures should be more appropriate to evaluate the performances of international stock markets. The evidence also indicates that various measures provide a vastly different performance ranking of the markets, albeit in the same direction.^ Finally, the inter-temporal stability of the international stock markets is investigated using the Parhizgari and Prakash (1989) algorithm for the Sen and Puri (1968) test which accounts for non-normality of return distributions. The empirical finding indicates that there is strong evidence to support the stability in international stock market movements. However, when the Anderson test which assumes normality of return distributions is employed, the stability in the correlation structure is rejected. This suggests that the non-normality of the return distribution is an important factor that cannot be ignored in the investigation of inter-temporal stability of international stock markets. ^

The relationship between the teacher's experience, the teacher's college major, and the teacher's level of education in predicting classroom attitudes in high school science students

A review of the literature reveals few research has attempted to demonstrate if a relationship exists between the type of teacher training a science teacher has received and the perceived attitudes of his/her students. Some of the teacher preparation factors examined in this study include the college major chosen by the science teacher, the highest degree earned, the number of years of teaching experience, the type of science course taught, and the grade level taught by the teacher. This study examined how the various factors mentioned, could influence the behaviors which are characteristic of the teacher, and how these behaviors could be reflective in the classroom environment experienced by the students.^ The instrument used in the study was the Classroom Environment Scale (CES), Real Form. The measured classroom environment was broken down into three separate dimensions, with three components within each dimension in the CES. Multiple Regression statistical analyses examined how components of the teachers' education influenced the perceived dimensions of the classroom environment from the students.^ The study occurred in Miami-Dade County Florida, with a predominantly urban high school student population. There were 40 secondary science teachers involved, each with an average of 30 students. The total number of students sampled in the study was 1200. The teachers who participated in the study taught the entire range of secondary science courses offered at this large school district. All teachers were selected by the researcher so that a balance would occur in the sample between teachers who were education major versus science major. Additionally, the researcher selected teachers so that a balance occurred in regards to the different levels of college degrees earned among those involved in the study.^ Several research questions sought to determine if there was significant difference between the type of the educational background obtained by secondary science teachers and the students' perception of the classroom environment. Other research questions sought to determine if there were significant differences in the students' perceptions of the classroom environment for secondary science teachers who taught biological content, or non-biological content sciences. An additional research question sought to evaluate if the grade level taught would affect the students' perception of the classroom environment. (Abstract shortened by UMI.) ^

Crossing boundaries to education: Haitian transnational families and the quest to raise the family up

Nearly 175, 000 Haitian immigrants have settled in South Florida since the 1970s. Their lives are often lived transnationally with persistent connections and obligations to family members in Haiti. Yet, traditional theories of immigrant assimilation focus on the integration of immigrants into host countries, giving little consideration to relationships and activities that extend into migrants' countries of origin. Conversely, studies of transnational families do not explicitly address incorporation into the receiving country. This dissertation, through the experiences of Haitian immigrants in South Florida, reveals a transnational quest "to raise the family up" through migration, remittances, and the pursuit of higher levels of education. I argue that familial duties and obligations, which have cultural foundations in the Haitian lakou, structure the activities of Haitian transnational families as they pursue socioeconomic advancement through migration and education. With the support of transnational families, many students cross boundaries to academic achievement and improve their opportunities for socioeconomic mobility in the US. With higher levels of education, these individuals contributed to a more favorable incorporation into the United States for their extended families, as well. The data were collected through participant observation and 78 in-depth interviews documenting the migration histories of 27 Haitian immigrant families in South Florida. This dissertation contributes to the existing literature on Haitian immigrants in the United States and to an understanding of the transnational dimensions of immigrant incorporation more broadly.

Genital human papillomavirus: Women's knowledge and attitudes of this sexually transmitted disease

The purpose of this study was to investigate women's knowledge and attitudes regarding genital human papillomavirus (n=100). Using a descriptive design, the Health Education Questionnaire was administered to 100 female patients (Mean Age = 33, SD = 7.17) at a physicians office in South Florida. The results indicated a lack of knowledge regarding genital human papillomavirus with 21 patients (21%) reported having knowledge and 79 (79%) having never heard of this disease. In addition, the group familiar with genital human papillomavirus also possessed a low level of knowledge with only 57% acknowledging an association of genital human papillomavirus and cervical cancer, 52% aware that a pap smear can detect the virus, 42% knowing that antibiotics can not treat the disease and 57% aware that it is not associated with a family history. An association was found between attitudes and health seeking behaviors. Subjects stating that they would take all measures to prevent genital human papillomavirus, were more likely to have a pap smear within the last year (Chi-square (1) = 4.33, p < .05). Higher levels of education and income were associated with increased knowledge regarding genital human papillomavirus when subjects were categorized according to sociodemographic characteristic (Chi-square (1) =9.45, p < .05; Chi-square (1) = 6.75, p < .05). There was no significant correlation between knowledge and ethnicity, marital status or age. Findings indicated the need for improved education and promotion of positive attitudes regarding human papillomaviurs in order to improve health seeking behaviors among women.
