Bioswales are a promising stormwater control measure (SCM) for roadway runoff management, but few studies have assessed performance on a field scale. A bioswale is a vegetated channel with underlying engineered media and a perforated underdrain to promote improved hydrologic and water quality treatment. A bioswale with a rip-rap lined forebay was constructed along state highway NC 211 in Bolivia, North Carolina, USA, and monitored for 12 months. Thirty-seven of the 39 monitored rain events exfiltrated into underlying soils, resulting in no appreciable overflow or underdrain volume. The bioswale completely exfiltrated a storm event of 86.1 mm. The one event to have underdrain-only flow was 4.8 mm. The largest and third-largest rainfall depth events (82.6 and 146 mm, respectively) had a large percentage (85%) of volume exfiltrated, but also had appreciable overflow and underdrain volumes exiting the bioswale, resulting in no peak flow mitigation. Overall, this bioswale design was able to capture and manage storms larger than the design storm (38 mm), showing the positive hydrologic performance that can be achieved by this bioswale. The high treatment capabilities were likely due to the high infiltration rate of the media and the underlying soil, longer forebay underlain with media, gravel detention layer with an underdrain, and shallow slope.

Violence against women (VAW) continues to exist as a pervasive, structural,systematic, and institutionalized violation of women’s basic human rights (UNDivision of Advancement for Women, 2006). It cuts across the boundaries of age, race, class, education, and religion which affect women of all ages and all backgrounds in every corner of the world. Such violence is used to control and subjugate women by instilling a sense of insecurity that keeps them “bound to the home, economically exploited and socially suppressed” (Mathu, 2008, p. 65). It is estimated that one out of every five women worldwide will be abused during her lifetime with rates reaching up to 70 percent in some countries (WHO, 2005). Whether this abuse is perpetrated by the state and its agents, by family members, or even by strangers, VAW is closely related to the regulation of sexuality in a gender specific (patriarchal) manner. This regulation is, on the one hand, maintained through the implementation of strict cultural, communal, and religious norms, and on the other hand, through particular legal measures that sustain these norms. Therefore, religious institutions, the media, the family/tribe, cultural networks, and the legal system continually disciplinewomen’s sexuality and punish those women (and in some instances men) who have transgressed or allegedly contravened the social boundaries of ‘appropriateness’ as delineated by each society. Such women/men may include lesbians/gays, women who appear ‘too masculine’ or men who appear ‘too feminine,’ women who try to exercise their rights freely or men who do not assert their rights as ‘real men’ should, women/men who have been sexually assaulted or raped, and women/men who challenge male/older male authority.

This article examines how freedom of speech is framed in the media controversy surrounding the Australian rugby player Israel Folau’s April 2019 Instagram post. A content analysis and framing analysis of newspaper reportage reveals that the controversy has been largely discussed in terms of whether or not Folau’s speech was being curtailed and whether this curtailing indicates a broader, ideologically motivated censoriousness. This discussion is problematic in that it says little about the actual substance of Folau’s post. This article argues that debates surrounding freedom of speech such as the one involving Folau could and should be enriched by an engagement with ethical principles. This engagement is premised on a commitment to the free exchange of views, while acknowledging that ‘speech’ is not always inherently beneficial for democracy, nor worth defending.

AbstractDuring the Soviet period, the media served as one of the main propagandist tools of the authoritarian regime, using a standardized and monotype media system across the Soviet Republics. After the collapse of the Soviet Union, 15 countries became independent. The transition from Soviet communism to capitalism has led to the reconstruction of economic, socio-cultural, and political systems. One of the most affected institutions in post-Soviet countries was the media. Media have played a supportive role during rough times, when there was, on the one hand, the struggle for liberation and sovereignty, and, on the other hand, the need for nation building. It has been almost 30 years since the Soviet Republics achieved independence, yet the media have not been freed from political control and continue to serve as ideological apparatuses of authoritarian regimes in post-Soviet countries. Freedom of speech and independent media are still under threat. The current study focuses on media use in Azerbaijan, one of the under-researched post-Soviet countries. The interviews for this study were conducted with 40 participants living in Nakhichevan and Baku. In-depth, semi-structured interview techniques were used as research method. Findings are discussed under six main themes in the conclusion.

AbstractFrom a theoretical and empirical linguistic point of view, this paper emphasizes the importance of the relationship between populism and the media. The aim of this article is to explore the language use of the Spanish right wing populism party Vox on the basis of its multimodal postings on the social network Instagram. For the analysis of their Instagram account, a suitable multimodal discourse analysis (MDA) provides a variety of methods and allows a theoretical integration into constructivism. A hashtag-analysis reveals that Vox’s ideology consists of a nativist and ethnocentric nationalism on the one hand and conservatism on the other. With a topos analysis, the linguistic realisations of these core elements are illustrated with two case studies.

This paper aims to investigate the language used by newspapers in post-revolutionary Iran. More precisely, the paper sets out to analyze how such a language is deployed to represent relevant hegemonic ideologies. The approach adopted for this purpose draws inspiration mainly from critical linguistics, where it is hypothesized that, as far as the pertinent metadiscourse goes, media genres serve to activate and perpetuate social power relations. In keeping with this theoretical stance, the paper argues that socially constructed texts can be said to perform two complementary functions; on the one hand, they shed light on the realities experienced in social life; on the other, they reveal such aspects of those realities as are constructed through the use of language. It is thus in this context that the media language used in the post-revolutionary Iran lends itself to analytical investigation, where the available data reveal the co-existence of three competing discourse processes of ‘Islamization’, ‘Iranian Nationalism’ and ‘Western liberalism’, relating to the third stage development of post-revolutionary Iran.

Infiltration estimation is made by tests such as concentric cylinders, which are prone to errors, such as the lateral movement under the ring. Several possibilities have been developed over the last decades to compensate these errors, which are based on physical, electronic, and mathematical principles. In this research, two approaches are proposed to measure the water infiltration rate in a silty loam soil by means of the mass values of a lysimeter weighing under rainfall conditions and different moisture contents. Based on the fact that with the lysimeter it is possible to determine acting soil flows very precisely, then with the help of mass conservation and assuming a downward vertical movement, 12 rain events were analyzed. In addition, it was possible to monitor the behavior of soil moisture and to establish the content at field capacity from the values of the weighing lysimeter, from which both approach are based. The infiltration rate of these events showed a variable rate at the beginning of the rainfall until reaching a maximum, to descend to a stable or basic rate. This basic infiltration rate was 1.49 ± 0.36 mm/h, and this is because soils with fine textures have reported low infiltration capacity. Four empirical or semi-empirical models of infiltration were calibrated with the values obtained with our approaches, showing a better fit with the Horton’s model.
