AbstractShaking and damage in the province of Groningen, the Netherlands, resulting from production-induced seismicity has caused increased public anxiety. Since 2014, production offtake has been reduced stepwise by over 50% in an attempt to minimise production-induced seismicity. The earthquake catalogue, combined with comprehensive data of the changes in production offtake, shows a clear response of seismic activity following the production measures taken. Associated temporal variations in the proportionality between smaller- and larger-magnitude events (the b-value of the Gutenberg–Richter relation) are observed. Since production measures were imposed, the b-value has tended to increase, thus lowering the probability of a larger-magnitude event. The analysis also shows increases in activity rate and b-value prior to larger-magnitude events. Subsequently, the probability of a larger-magnitude event seems to be decreasing prior to the events occurring. This implies that for short-term earthquake prediction of hydrocarbon-production-induced seismicity, these types of analysis could be misleading. However, regional analysis is necessary to explain the observations in terms of rupture initiation. At present, each event felt still draws the interest of both public and press. As some clustering of events in both time and space is still observed, managing both the seismicity and the public perception provides a continuing challenge.

Pharmaceuticals agglomerations consistently use their brand image and versatile product portfolios to consolidate their position in the financial sector, which is evident in their continuous profit making and expansion in market share. This paper explores the short-term and long-term investment attractiveness through ‘consumer centric decision’ approach in two selected pharmaceutical companies, Renata Limited and Orion Pharma Limited, of Bangladesh over the last three years’ period. This research adopts a systematic approach which primarily addresses the various concerns of investors to illustrate the decision-making process of the existing and future investors. Using primarily domestic transaction data, this study explores how the leading pharmaceuticals companies of Bangladesh effectively use the wide array of drug portfolios mix with appropriate branding techniques to increase their financial profit and market share simultaneously. Both SWOT analysis and Porters Five Forces Model explore the business analysis of Renata Limited in compare to Orion Pharma Limited that provides a conclusion regarding investors’ decision to invest in Renata Limited. Considering the financial analysis, Renata’s financial liquidity is not very satisfactory and could have been improved further if management is prudent on financial strategy settings. Findings of the business analysis indicate that Renata Limited would be a good investment choice for existing and prospective shareholders based on its opportunities for long term and short term growth and further expansion in developing the market. The results suggest that even lower liquidity coupled with higher interest borrowings can be balanced by posing positive picture to the public shareholders by returning the positive dividend to them.

This paper briefly summarizes evidence for the influence of popular films on public perception of government and on public policy.  Two films examined through the lens of public administration, and the lessons they teach about public administration, are exposed.  One film, Ghostbusters conveys a strongly negative image, and the other, A Thousand Heroes a strongly positive message.  Only Ghostbusters was and remains popular and profitable.  Public information efforts by government and the public administration community have been limited or reactive.  The authors argue for the increased support for public information initiatives such as those of the Public Employees Roundtable (PER) and  the American Society of Public Administration (ASPA).

When the hashtag #metoo began to circulate in digital and social media, it challenged a familiar interpretation of those who are raped or sexually harassed as victims, positioning women as embodied agents. Yet, almost exactly a year after the #metoo movement shot to visible prominence, a different, though eerily similar, story began to circulate on the same multi-media platforms as #metoo: a story about white male victimhood. Powerful men in positions of privilege (almost always white) began to take up the mantle of victimhood as their own, often claiming to be victims of false accusations of sexual harassment and assault by women. Through the analysis of five public statements by highly visible, powerful men who have been accused of sexual violence, I argue that the discourse of victimhood is appropriated not by those who have historically suffered but by those in positions of patriarchal power. Almost all of the statements contain some sentiment about how the accusation (occasionally acknowledging the actual violence) ‘ruined their life’, and all of the statements analyzed here center the author, the accused white man, as the key subject in peril and the authors position themselves as truth-tellers about the incidents. These statements underscore certain shifts in the public perception of sexual violence; the very success of the #metoo movement in shifting the narrative has meant that men have had to defend themselves more explicitly in public. In order to wrestle back a hegemonic gender stability, these men take on the mantle of victimhood themselves.

This article examines Canadian author Shaughnessy Bishop-Stall’s 2004 memoir Down to This: Squalor and Splendour in a Big-City Shantytown through the notions of marginalia and the ordinary in order to question dichotomic representations of homelessness. It explores how the author moves beyond binaries, interrogating the dichotomy ordinary/out of the ordinary lives by narrating his ethical encounter with the other (Butler, 2004). The text is written as a journal where Bishop-Stall describes his personal journey through homelessness; and more importantly, it gives a voice to the other down-and-out people in notorious Toronto’s Tent City. The characters’ unreliable and fragmented storytelling uncovers the lives of the faceless others. I contend that in Down to This individuals’ life stories are connected to realities which question binaries through the re/mapping of ordinary experiences and affects; they disintegrate the opposition materiality vs abstraction, or as I argue, exclusion vs inclusion (out of the ordinary/ordinary). Down to These bridges the private details of the residents’ life stories, and the public perception of the problem of homelessness, illustrating how everyday moments of precarity intersect with wider political issues. In the process, the narrative also questions the binary attitudes of exclusion (disfranchisement) and inclusion (privilege). This literary strategy gives the constellation of stories a profound illuminating vision of the human condition. I show my point by drawing on the of marginalia (Kistner 2014), and by analysing the characters’ narratives of precariousness through the notions of editing and affective assemblage (Gerlach, 2015; Hamilakis, 2017).

Urbanization projects, understood as those supplying basic services for cities, such as drinking water, sewers, communication services, power, and lighting, are normally short-term extremely scattered actions, and it can be difficult to track their environmental impact. The present article’s main contribution is to employ the project budgets of public urbanization work to provide an instrument for environmental improvement, thereby helping public procurement, including sustainability criteria. Two urban projects in Seville, Spain are studied: the first substitutes existing services, and the second also includes gardens and playgrounds in the street margins. The methodology finds the construction elements that must be controlled in each project from the perspective of three indicators: carbon, water footprints, and embodied energy. The main impacts found are due to only four construction units: concrete, aggregates, asphalt, and ceramic pipes for the sewer system, that represent 70% or more of the total impact in all indicators studied. The public developer can focus procurement on those few elements in order to exert a lower impact and to significantly reduce the environmental burden of urbanization projects.

This paper explores women’s participation in parliamentary elections in post-Soviet Kyrgyzstan. Using various methods, it offers an interdisciplinary perspective on factors that affect the likelihood of women participating successfully in parliamentary elections. This study supports the general literature on the effects of gender quotas and proportional representation, but its results on other factors are mixed. The factor of financial resources is significant, though its impact has been reduced with the introduction of gender quotas, while other factors—such as social status—may not be particularly important. The public perception of a woman in politics is not the greatest obstacle to women’s representation, and a female candidate’s professional status may often be attractive to party leaders.

An algorithm to determine the maximum temperature of brake systems during repetitive short-term (RST) braking mode has been proposed. For this purpose, the intermittent mode of braking was given in the form of a few cyclic stages consisting of subsequent braking and acceleration processes. Based on the Chichinadze’s hypothesis of temperature summation, the evolutions of the maximum temperature during each cycle were calculated as the sum of the mean temperature on the nominal contact surface of the friction pair elements and temperature attained on the real contact areas (flash temperature). In order to find the first component, the analytical solution to the one-dimensional thermal problem of friction for two semi-spaces taking into account frictional heat generation was adapted. To find the flash temperature, the solution to the problem for the semi-infinite rod sliding with variable velocity against a smooth surface was used. In both solutions, the temperature-dependent coefficient of friction and thermal sensitivity of materials were taken into account. Numerical calculations were carried out for disc and drum brake systems. The obtained temporal variations of sliding velocity, friction power and temperature were investigated on each stage of braking. It was found that the obtained results agree well with the corresponding data established by finite element and finite-difference methods.
