The cotton strip assay uses the loss of tensile strength of cotton strips as a measure of microbial cellulolytic activity. Its suitability for measuring general microbial activity in groundwater was tested by examining the relationship of tensile strength, abundance of cellulolytic organisms and general microbial activity on cotton strips deployed in bores. The hypothesis was that the strength of cotton strips would decline with increasing abundance and activity of cellulolytic organisms, and as cellulolysis makes resources available to other microbial groups, cotton strength loss should also be related to increased overall microbial activity. The correlation between the abundance of cellulolytic organisms and cotton strength was not significant. Two main factors influenced this relationship: (i) effectiveness of the media in detecting cellulolytic moulds and (ii) inter-community interactions. After accounting for the presence of moulds through partial correlation, the relationship between tensile strength and abundance of cellulolytic organisms was stronger and significant. Both cotton strength and abundance of cellulolytic organisms correlated significantly with general microbial activity. These results support the use of the cotton strip assay, and cotton tensile strength as a surrogate for microbial activity in groundwater.

AbstractThis article considers the relationship of international law and the media through the prism of human rights. In the first section the international regulation of the media is examined and visions of good, bad, and new media emerge. In the second section, the enquiry is reversed and the article explores the ways in which the media is shaping international legal forms and processes in the field of human rights. This is termed the ‘mediatization of international law’. Yet despite hopes for new media and the Internet to transform international law, the theoretical work of Jodi Dean warns of the danger to democracy of commodification through the spread of ‘communicative capitalism’.

This study presents a model linking individual characteristics, employee engagement, and employee performance. The primary objective was to investigate the direct effect of individual characteristics on employee performance and its indirect effect through employee engagement. This study used a non-probability sampling technique with a saturation sampling type. The data were obtained by a questionnaire from a sample of 118 respondents of millennial employees in the media and information technologies sector in Yogyakarta. Data were analyzed by used variance-based SEM (SEM-PLS) and found four significant paths models. The result reveals that individual characteristics have a positive and significant effect on improving employee performance. Moreover, individual characteristics are significantly positive in increasing employee engagement, while employee engagement has a positive and significant effect on employee performance. The mediation test result indicated that employee engagement could partially mediate the relationship of individual characteristics on employee performance. Further research can incorporate variables that influence millennial performance, such as job characteristics, intention to leave, job satisfaction, and other variables to improve strategies in enhancing millennial performance.

The authors consider identity as a conditional discursive construct, the result of subjects of discourse identifications and offer their own methodology for its analysis. It is shown that regional identity can be represented in the form of a model based on spatial and temporal identifications that specify the coordinate system of reality in which there are residents of the region in question. The concept of space-time is complemented by a set of diverse thematic identifications, including economic, political, cultural, ethnic, religious, linguistic, etc. For the first time in the framework of the socio-constructionist paradigm, a discursive model of the regional identity of the inhabitants of Tatarstan is constructed in the article. The empirical material of the study is the corpus of texts of Tatarstan media for 2017-2019. It is shown that the spatial identification of Tatarstan people includes the practice of selecting, nominating and describing significant geographical objects, the practice of constructing relations of Tatarstan with other geographical objects. Particular attention is paid to the practice of constructing the capital status of a regional center, as well as the relationship of spatial and political identifications. Analyzing the practices of ethnic, religious, linguistic and cultural identification, the authors come to the conclusion that the identity of the Tatarstan people is ethnocentric: despite the declared multinationality and multi-confessionality of the region, Tatars as an ethnic group, Tatar language, Tatar culture and Islam as a traditional religion of the Tatars are of particular importance.

Chapter Six provides an extended examination of the newspaper reporting of the treason trial of Obafemi Awolowo, the second major treason trial after independence. How the Nigerian press covered the trial illuminates the ways in which legal process as a mode of nation formation was woven into the daily lives of newspaper readers. Moreover, attending to that press coverage illustrates the importance of narrative and literary form in the process of national self-construction. The chapter begins by outlining the relationship of politics and the press in Nigeria before looking at the defining features of the trial itself. The chapter examines how the trial was presented in the press and the readerly engagement that the press sought to foster. The chapter concludes by reflecting on the larger significance of the trial and its coverage in the media at the dawn of Nigeria’s first Republic.

The study has explored the rising psychological changes with the media convergence of television and Facebook and significance of a positive approach to deal with hierarchical conduct of employee in any company. The study investigates the brand advertisement showcasing balance of personal and professional life in the relationship of wife and husband at same work place. The study focused on semiotic approach to analyze the advertisement of Airtel India emphasizing on social roles of women in the society and its impact on the users of Facebook. The researcher analyzed the hegemony in the commercial and promotion of advertisement on public platform as face book to know the impact on consumer towards the commercial. Initially television is used as a medium the commercial was also released through Facebook with a strong brand communication strategy. The findings revealed that the observational information shared on Facebook affirms a portion of positive hierarchical conduct, that concentrates on the enticing urge in the consumers / users to aspire, visualize, share the views about the commercial with emotions on the face book page showcasing positive consumer psychology.

This paper studies relationship between soil-cement parameters and unconfined compressive strength. The research in tensile strength and deformation modulus of soil-cement is an important basis for soil-cement failure mechanism and intensity theory. They also impact cracks, deformation and durability of cement-soil structure. Shear strength and deformation of soil-cement is important to the destruction analysis and finite element calculations. Therefore it needs to study on tensile strength, shear strength and deformation modulus of soil-cement. Based on previous experiments, the relationship of tensile strength, shear strength, deformation modulus and unconfined compressive strength of soil-cement are quantitatively studied.

Abstract The ter Meulen method for the direct determination of oxygen has been adapted, with modifications, to the analysis of raw and vulcanized rubbers. Raney nickel has been found to be quite effective as the reducing catalyst and to be satisfactorily resistant to sulfur poisoning. The method has been applied to the study of the aging of vulcanized rubber in the Geer oven and oxygen bomb. From this study the following conclusions may be drawn: (1) The increase in combined oxygen is greater in the oxygen bomb than in the Geer oven. (2) Deterioration of rubber in the oxygen bomb involves oxidation primarily, whereas that occurring in the Geer oven involves not only oxidation but also thermal decomposition followed by volatilization of oxidation products. (3) The effectiveness of an antioxidant in retarding the absorption of oxygen in oxygen-bomb aging agrees well with its ability to maintain the physical properties of the stock in which it is present. (4) The deterioration in physical properties of a rubber stock in the oxygen bomb during the early stages of aging is a linear function of the increase in combined oxygen. For stocks containing antioxidants and diphenylguanidine as the accelerator, an increase in combined oxygen of approximately 1.2% corresponds to a decrease in tensile strength of 50%. (5) The relationship of increase in combined oxygen to decrease in tensile strength seems to be affected not only by antioxidants, but also by accelerators of vulcanization.

Modern media has led to changes in the scope, intensity and effectiveness of communication. The Internet medium, which offers almost unlimited dialogue and polylogue possibilities, has become an attractive place for provocation to be born and function. The provocative narrative not only inspires these processes, but also becomes as a result of such a genre modification. This article analyzes a provocative discourse, the Lithuanian version of the global movement MeToo, which promotes the publication of cases of sexual harassment: testimonies of women who have been sexually harassed, publications in the media discussing the issue, interviews with discourse participants, another type of comments. The MeToo discourse is characterized by a rhetorical aspect: the concept of provocation as an effective communication strategy is explored; the relationship of the provocative narrative to the genre category is discussed; characteristic rhetorical elements – invention, disposition, elocution – have been distinguished.
