The Impact

This chapter compares 4 variants of metaheuristics (RFA, EMVO, RPSO, and RBAT). The purpose is to test the impact of refinement on different types of metaheuristics (FA, MVO, PSO, and BAT). The refinement helps to enhance exploitation and to speed up the search process in multidimensional spaces. Moreover, it presents a powerful tool to solve different issues such as slow convergence. The different methods have been used for gene selection on 11 microarrays datasets to solve their various issues related to the presence of irrelevant genes. The obtained results reveal the positive impact of refinement on FA, MVO, and PSO, where all performances have been improved. On the other hand, this process harmed the BAT algorithm. The comparative study between the 4 variants highlights the efficiency of EMVO and FA in terms of precision and dimensionality reduction, respectively. Overall, this study suggests drawing attention to the choice of embedded metaheuristics in the refinement procedure, where powerful methods in exploration are recommended. Moreover, metaheuristics that risk form fast convergence are not advised.

Purpose The purpose of this paper is to describe and analyze the rules on the formation of contracts under Korean law and the Contracts for the International Sale of Goods (CISG) in a comparative way and introduce the relevant proposed rules under the Amendment Draft of the Korean Civil Code (KCC). In addition, it attempts to compare and evaluate them in light of the discipline of comparative law. Design/methodology/approach In order to achieve the purposes of the study, it executes a comparative study of the rules as to the formation of contracts of the CISG, Korean law and the Amendment Draft of the KCC. The basic question for this comparative study is placed on whether a solution from one jurisdiction is more logical than the others and to what extent each jurisdiction has responded to protect the reasonable expectations of the parties in the rules as to the formation of contracts. Findings The comparative study finds that most of the rules under the CISG are quite plausible and logical and they are more or less well reflected in the proposals advanced by the KCC amendment committee. On the other hand, the other rules under the CISG which have brought criticisms in terms of their complexity and inconsistent case law invite us their revision or consistent interpretation. The drawbacks of the CISG have also been well responded in the Amendment Draft of the KCC. Nevertheless, it is quite unfortunate that the Amendment Draft of the KCC still has a rule that regards any purported performance with non-material alteration of the terms of an offer as an acceptance. Originality/value This study may provide legal and practical advice to both the seller and the buyer when they enter into a contract for international sales of goods. In addition, it may render us an insight into newly developed or developing rules in this area and show us how they interact with each other. Furthermore, it may be particularly useful in Korea where there is an ongoing discussion for revision of the KCC.

The Impact

This research explored the impact of job satisfaction, the ethical behavior of coworkers, successful managers, and employees themselves. Also explored were six types of ethical climate on organizational commitment and its three dimensions, including affective, continuance, and normative commitment through an investigation on 476 Chinese insurance agents. The empirical results showed that ethical behavior of coworkers and a caring climate had a significantly positive impact on both organizational commitment and its three dimensions, while independence climate had no significant influence on overall organizational commitment or its three dimensions. Job satisfaction, ethical behavior of successful managers and employees themselves, and the other five types of ethical climates only had a significant impact on organizational commitment or some of its dimensions.

AbstractWe try to analyze the impact of Chinese Textile and Garment (T&G) imports, and the internal and external factors to the firm survival and growth of T&G industry in Indonesia, for the period study of 2002 to 2007. Probit regression model is used to analyze the impact of Chinese imports to the survival of firm, while OLS regression model is used to analyze its growth. It shows that the ability of firms' survival is influenced by the internal and external factors. The Chinese imports give positive impact to the firms' survival ability. On the other hand, firm's growth is only affected by its internal characteristics, while the impact of Chinese imports is proven not significant. The Heckman test result stated that there are no correlation between firms' ability to survive and the firm growth behavior.Keywords: Growth, Survival, Chinese Imports, Textile, Indonesian Textile and Garment IndustryAbstrakStudi ini menganalisis dampak dari penetrasi impor TPT Cina, faktor internal, serta faktor eksternal terhadap kebertahanan dan pertumbuhan perusahaan dalam industri TPT Indonesia periode tahun 2002-2007. Metode probit regression digunakan untuk mengetahui dampak impor Cina terhadap kebertahanan perusahaan, sementara regresi linear sederhana (OLS) digunakan untuk menganalisis pertumbuhannya. Ditemukan bahwa kebertahanan perusahaan dipengaruhi oleh karakteristik internal dan eksternal, serta impor Cina yang memberikan dampak positif. Sementara pertumbuhan perusahaan hanya dipengaruhi oleh faktor internal, di mana impor Cina tidak memberikan dampak signikan. Hasil pengujian Heckman menyatakan tidak ada indikasi hubungan antara kebertahanan perusahaan dengan perilaku pertumbuhannya.Kata kunci: Pertumbuhan, Kebertahanan, Impor Cina, Tekstil, Industri Tekstil dan Produk Tekstil Indonesia

The main attention of the submitted paper is devoted to the comparison of development of entrepreneurship in Slovak and Polish small and medium-sized he enterprise sector. The conditions for blooming entrepreneurship are created in the national economy. Especially the role of SMEs in the transition economy, both in Slovakia and Poland, has the impact on SMEs. The entrepreneurship of small and medium-sized enterprises is extended in the whole Slovakia. From the viewpoint of the regional structure, most enterprises are located in the Bratislavský region (30.4%), Košický region (11.8%), Žilinský region (10.1%) and Trenčianský region (10.1%). On the other hand, the least of enterprises were registered in the Nitrianský region (8.9%), Trnavský region (9.2%) and Banskobystrický region (9.6%). Small and medium entrepreneurship is diversed throughout Poland. The average small and medium entreprenership ratio is 44.5, while the highest is in the Mazowieckie region – 55.2% and the lowest in the Podkarpackie region – 30 %. The supporting system for private entrepreneurship in both countries, Slovakia and Poland, is very similar and the entrepreneurs are satisfied with its offer and help.

The Comparative Study

The several forms of preferential mating, such as cross-cousin marriage, sororate and levirate, are well known and have been reported from all the ethnographic provinces of the world. Lately Lowie and Rivers have devoted special chapters in their books on social organization to the comparative study of these important institutions. Lowie has pointed out that there is strong evidence for the correlation of sororate and levirate. The later publication of Rivers hardly serves to make these matters any clearer than Lowie's work. Although the latter scholar, with Tylor and others, recognized the close connexion existing between sororate and levirate, the evidence at his disposal did not allow him to arrive at a similar conclusion with regard to the other forms of preferential marriage. Accordingly he had to treat them, for the time being, as institutions of independent origin.

This article provides a partial but necessary review of the dominating themes, evolution, and pending tasks that await the comparative politics of federalism. The basic premise of this article is taken from rational choice institution-alism. The article fist delimits federalism as an institution, before it pays attention to the impact of federalism on democracy and the workings of the economy. An analysis of federalism as an endogenous institution is provided. The article also mentions a number of methodological considerations on the comparative study of the origins and consequences of federalism. It ends with a discussion of the various challenges that lie ahead of the field.

Privacy has long been an important issue for IT systems that handle personal information, and is further aggravated as technology for collecting and analyzing massive amounts of data is becoming increasingly effective. There are methods to help practitioners analyze the privacy implications of a system during the design time. However, this is still a difficult task, especially when dealing with Internet of Things scenarios. The problem of privacy can become even more unmanageable with the introduction of overspecifications during the system development life cycle. In this paper, we carried out a controlled experiment with students performing an analysis of privacy implications using two different methods. One method aims at reducing the impact of overspecifications through the application of a goal-oriented analysis. The other method does not involve a goal-oriented analysis and is used as a control. Our initial findings show that conducting a goal-oriented analysis early during design time can have a positive impact over the privacy friendliness of the resulting system.

The small respiratory passages dysfunction (SRPD) is found in the vast majority of patients with bronchial asthma (BA). The SRPD is currently recognized as the important pathogenetic feature of BA. The purpose of this review is to analyze the current scientific knowledge about the poorly studied aspects of the small respiratory passages (SRR) participation in the development of pathological process in BA, as well as the impact of small bronchial dysfunction on the clinical course, the exacerbation frequency and the disease control. The importance of SRPD diagnostics in BA patients for optimal and timely treatment is discussed. The modern methods of RPD pathology diagnostics are described; their informative use in the comparative study aspect is considered.

This article is a comparative study of regional differences in social and political value orientations. I identify four central sets of value orientations: two Old Politics orientations – religious–secular and economic left–right; and two New Politics orientations – libertarian/authoritarian and green values. I use the international value studies from 15 West European countries as my empirical base. The article addresses three major research problems: (1) Which of the four value orientations is most strongly anchored in regional differences, and in which countries do we find the largest value differences between the regions? (2) Do we find the same ranking of the regions across the four value orientations, or do the value orientations group the regions in separate ways? (3) Can the other socio-structural variables explain the impact of region on value orientations, or is that impact unique? The average correlations between regions and each of the four value orientations are similar but somewhat larger for religious value and libertarian/authoritarian values. With regard to the second research problem, I hypothesize one-, two-, and three-dimensional solutions based on different spatial configurations. The one-dimensional configurations implied that there exist some (centre) regions that have secular, economic rightist, green, and libertarian regions, and (peripheral) regions with opposite value orientations. This pattern is clearly found in four countries. The expected two-dimensional solution with an Old Politics and a New Politics dimension was found in four countries, whereas the expected three-dimensional solution with two Old Politics and one New Politics dimension was found in three countries. In the multivariate analysis examining the causal impact of region, only a small portion of the correlation between region and value orientations was spurious when controlling for the other (quasi-)ascriptive variables. Furthermore, only a small portion of the impact of region was transmitted via social class variables.

And Performance

This paper investigates the effects of gaze-based player guidance on the perceived game experience, performance, and challenge in a first-person exploration game. In contrast to existing research, the proposed approach takes the game context into account by providing players not only with guidance but also granting them an engaging game experience with a focus on exploration. This is achieved by incorporating gaze-sensitive areas that indicate the location of relevant game objects. A comparative study was carried out to validate our concept and to examine if a game supported with a gaze guidance feature triggers a more immersive game experience in comparison to a crosshair guidance version and a solution without any guidance support. In general, our study findings reveal a more positive impact of the gaze-based guidance approach on the experience and performance in comparison to the other two conditions. However, subjects had a similar impression concerning the game challenge in all conditions.
