Effects of weft count and weft density on the surface roughness of 3/1 (Z) twill woven fabric

Purpose The purpose of this study is to investigate the effects of weft yarn diameter and pick density on the properties of surface roughness (SMD) of 3/1 (Z) twill-woven fabrics in three measurement directions weft (0°), the warp (90°) and the diagonal (45°). Design/methodology/approach Nine 3/1 (Z) twill samples were prepared with two factors and three levels and their roughness values were measured in the weft (0°), warp (90°) and diagonal (45°) directions of 3/1 (Z) twill fabrics using the Kawabata-FB4 instrument. Analysis of variance (ANOVA) is used to determine the effect of weft yarn diameter and pick density on SMD properties and comparisons were done in the weft (0°), the warp (90°) and the diagonal (45°) directions. Findings From experimental analysis, weft yarn diameter and pick density affect SMD of 3/1 (Z) twill-woven fabrics in both diagonal (45°) and weft (0°) directions but slightly affect warp (90°) direction. Maximum SMD values were observed in diagonal (45°) directions and the minimum was in warp (90°) directions of fabrics. Weft yarn diameter and pick density are statistically significant on SMD values of 3/1 (Z) twill-woven fabrics for three directions at a 95% confidence interval. Parameter variation in weft directions of 3/1 (Z) twill-woven fabrics also varies SMD values in three directions measurements Originality/value The findings of this study can be usually used for textile technology, industries and laboratories to create a basic understanding for measuring roughness properties of 3/1 (Z) twill fabric. It is also possible to identify the surface characterizations in different directions of measurement for their usage in some specific areas of end application like consumer goods, home textiles, technical textiles, etc.

How Air Quality Affect Health Industry Stock Returns: New Evidence From the Quantile-on-Quantile Regression

This paper discusses the asymmetric effect of air quality (AQ) on stock returns (SR) in China's health industry through the quantile-on-quantile (QQ) regression method. Compared to prior literature, our study provides the following contributions. Government intervention, especially industrial policy, is considered a fresh and essential component of analyzing frameworks in addition to investors' physiology and psychology. Next, because of the heterogeneous responses from different industries to AQ, industrial heterogeneity is thus considered in this paper. In addition, the QQ method examines the effect of specific quantiles between variables and does not consider structural break and temporal lag effects. We obtain the following empirical results. First, the coefficients between AQ and SR in the health service and health technology industries change from positive to negative as AQ deteriorates. Second, AQ always positively influences the health business industry, but the values of the coefficients are larger in good air. In addition, different from other industries, the coefficients in the health equipment industry are negative, but the values of the coefficients change with AQ. The conclusions provide important references for investors and other market participants to avoid biased decisions due to poor AQ and pay attention to government industrial policies.

Innovating (a Lot) With a Little: High-Tech Innovation in Southeast Europe

Motivation: According to the European Innovation Scoreboard (EIS, 2020), Southeast-European countries are either modest or moderate innovators because they consistently innovate below the EU average. Given that innovation is a key driver of economic growth (Hasan & Tucci, 2010), this implies that Southeast Europe has been economically falling back while simultaneously politically integrating with the EU. However, the EIS categorizes countries according to the inconclusive arithmetic mean of indicators for firm-level innovation (bottom-up) and indicators for inputs and enablers of innovation at the national level (top-down). Besides, it does not separately assess innovation performance of high-technology industries although these are crucial for international competitiveness (Schwab, 2019). Consequently, this paper answers the following research question: What is innovation performance of high and medium-high technology industries in Southeast Europe in comparison to the EU average? Idea: In contrast to the EIS which merges top-down with bottom-up innovation indicators, the core idea of this paper has been to analyse only bottom-up data on comparative innovation performance of high and medium-high technology industries in Southeast Europe. Method and data: The paper methodologically draws on guidelines for collecting, reporting, and using data on innovation by Oslo Manual (OECD & Eurostat, 2018), and uses secondary data from 2010-2016 Community Innovation Surveys of enterprises to compile an own set of 140 data points. Innovation activity within an industry is defined as the ratio of innovative enterprises to the total population of enterprises while innovation performance is the ratio of innovation activity in the respective country to innovation activity of this industry in the whole EU. Tools: All data points have been arranged country-wise as unbalanced contingency panels and plotted to draw conclusions on innovation performance of high and medium-high technology industries in Southeast Europe. Findings: Although all top-down innovation inputs and enablers at the national level are far below the EU average throughout Southeast Europe, several industries in the region reach or surpass the average EU innovation performance: the pharmaceutical industry in Croatia, all medium-high technology industries in Turkey, manufacture of machinery in North Macedonia and Serbia, as well as manufacture of motor vehicles in all countries except for Romania. Contributions and limitations: This is the first known paper to benchmark innovation performance of high and medium-high technology industries throughout Southeast Europe. In addition, the paper reveals the shortcomings of the whole-country method employed by the EIS since it clearly points out that innovation performance of national industries should be assessed instead. Limitations of the paper are the exclusive focus on innovation as a process and partly restricted data availability.

The dynamics of industrial geographic distribution: evidence from Brazil (2002-2014)

ABSTRACT The geographical distribution of Brazilian industries changed between 2002 and 2014, and it was more significant for some industries. Based on Dumais et al. (2002), we explore the dynamics of these changes by a decomposition of the employment variation and concentration index for manufacturing industries grouped by technological intensity, and we identify the direction of the locational movements of the firms among microregions. In general., the results indicate that between 2002 and 2014, there was a trend of convergence among the microregions’ participation in industrial employment, contributing to industrial deconcentration in the country, with the exception of the group of high-technology industries, which became more concentrated. Components of the life cycle of industries, especially the growth of employment generated by new industries in non-metropolitan microregions, are identified as main propelling of this evidence. In general., the results are consistent with the importance of agglomeration economies over historic accidents to explain the industrial concentration in Brazil between 2002 and 2014.

Copyright Protection for The Works of Sae Lecturers and Students in The Creative Media Field in The Instant Gratification Era

The protection of ideas or creativity on the work, especially the work of students and lecturers in the creative media field is still not maximized. This can be seen from the rampant piracy of works in the music, information technology, publishing, film, and animation industries. In addition, there are still other problems such as plagiarism of written works, and licensing, especially for the music, photography, and information technology industries. Therefore, it is necessary to have a regulation related to the protection of the works of lecturers and students. The author uses the Normative Juridical research method. The results of the study indicate that the era of instant gratification that was born from technological advances can also have positive and negative impacts, and the protection of the works of lecturers and students who have not been commercialized and are still in the form of drafts that need to be developed further (not yet real) is still not maximized.

Firm and Board Characteristics, and E-Waste Disclosure: A Study in the Era of Digitalisation

Business sectors face the advent of digitalisation, bringing attention to e-waste, or waste generated from obsolete electrical and electronic appliances. In addressing this issue, the study intends to examine e-waste disclosure by Bursa Malaysia listed firms. Specifically, this study investigates the extent and quality of e-waste disclosure, observes whether the reporting differs between industries and the boards on which the firms are listed, and investigates if e-waste disclosure is associated with firm and board characteristics. A total of 92 firms in the telecommunication and technology industries, listed on the Main and Ace boards of Bursa Malaysia, were selected as samples. The results reveal that despite an indication that e-waste reporting applies to the two sectors, only 16% of the firms report their commitment to managing e-waste. The disclosure shows how e-waste reporting is low in quantity and is circulated with only very general, qualitative information. An independent sample t-test reveals that firms listed on the Main board report significantly more e-waste information than their counterparts. Another t-test indicates an insignificant difference in e-waste disclosure between the firms under study. Furthermore, firm size significantly impacts e-waste disclosure, while firm performance, board size, and board gender diversity show insignificant impact. The results of this preliminary study shed some light on business firms’ commitment towards their e-waste management and reporting, which is a substantial factor for Malaysia to achieve environmental sustainability.

PEMBATASAN TERHADAP PERSAINGAN UNTUK MEMBENTUK PASAR DALAM KASUS STANDARD ESSENTIAL PATENT (SEP) (PERBANDINGAN HUKUM PERSAINGAN USAHA DI INDONESIA DAN UNI EROPA)

The role of patents is complex when dealing with the problem of technological interoperability in cases where patented technology becomes standard. In such cases, a balance is needed between the protection of the interests of the inventor, i.e. the standard essential patent (SEP) holder, and of users who need the technology to enter the market. There is a susceptibility to restrictions on competition to create markets (competition for the market). Market dominance can be created by the adoption of SEP holder technology as a standard and hence, a key for other business actors to enter the market. With the potential for the formation of a dominant position in the relevant market, the competition law intervention is required when patent abuse occurs, as it appears typical in the pharmaceutical and information technology industries. The normative research examines how competition law in the European Union deals with SEP cases in comparison to Indonesian competition law.
