ABSTRACTThermodynamic data for the arsenates of various metals are necessary to calculate their solubilities and to evaluate their potential as arsenic storage media. If some of the less common arsenate minerals have been shown to be less soluble than the currently used options for arsenic disposal (especially scorodite and arsenical iron oxides), they should be further investigated as promising storage media. Furthermore, the health risk associated with arsenic minerals is a function of their solubility and bioavailability, not merely their presence. For all these purposes, solubilities of such minerals need to be known. In this work, a complete set of thermodynamic data has been determined for mansfieldite, AlAsO4·2H2O; angelellite, Fe4(AsO4)2O3; and kamarizaite, Fe3(AsO4)2(OH)3·3H2O, using a combination of high-temperature oxide-melt calorimetry, relaxation calorimetry, solubility measurements, and estimates where possible and appropriate. Several choices for the reference compounds for As for the high-temperature oxide-melt calorimetry were assessed. Scorodite was selected as the best one. The calculated Gibbs free energy of formation (all data in kJ·mol–1) is –1733.4 ± 3.5 for mansfieldite, –2319.2 ± 7.9 for angelellite and –3056.8 ± 8.5 for kamarizaite. The solubility products for the dissolution reactions are –21.4 ± 0.5 for mansfieldite, –43.4 ± 1.5 for angelellite and –50.8 ± 1.6 for kamarizaite. Available, but limited, chemical data for the natural scorodite–mansfieldite solid-solution series hint at a miscibility gap; hence the non-ideal nature of the series. However, no mixing parameters were derived because more data are needed. The solubility of mansfieldite is several orders of magnitude higher than that of scorodite. The solubility of kamarizaite, on the other hand, is comparable to that of scorodite, and kamarizaite even has a small stability field in a pH-pε diagram. It is predicted to form under mildly acidic conditions in acid drainage systems that are not subject to rapid neutralization and sudden strong supersaturation. The solubility of angelellite is high, and the mineral is obviously restricted to unusual environments, such as fumaroles. Its crystallization may be enhancedviaits epitaxial relationship with the much more common hematite. The use of the scorodite–mansfieldite solid solution for arsenic disposal, whether the solid solution is ideal or not, is not practical. The difference in solubility products of the two end-members (scorodite and mansfieldite) is so large that almost any system will drive the precipitation of essentially pure scorodite, leaving the aluminium in the aqueous phase.
Trans Surgeries and Cosmetic Surgeries
Authors: Heyes Cressida J. , Latham J. R. 
Published: May 2018

AbstractThis article examines the various possibilities for making an analogy or disanalogy between cosmetic and trans surgeries, focusing on the suggestion that trans surgeries are medically necessary while cosmetic surgeries are not—a position that has a great deal of rhetorical force. The authors argue that this disanalogy both fails to understand the complexity of the justifications used by recipients of these diverse surgeries and should be seen as symptomatic of various attempts in medical practice to impose particular understandings of suffering, gender identity, and gender politics on trans patients. The appeal to the intense and intrinsic suffering of the trans patient because they cannot become the normatively gendered person they always believed themselves to be, the authors argue, elides the diversity of trans experience as well as coerces trans patients into a politics of ressentiment.
Surgical Subjects and the Right to Transgender Health in Brazil
Authors: Franklin Joshua 
Published: May 2018

Abstract
In 2007, a Brazilian federal appeals court ruled that gender affirming care was guaranteed on the basis of the constitutional right to health. This is part of a broader process of the “judicialization” of the right to health in Brazil. In this essay, the author draws on fourteen months of ethnographic fieldwork conducted at a public gender clinic in southern Brazil to consider the experiences of transgender people who accessed surgery through the expanded public services that followed the litigation. The article argues that access to surgery does not, by itself, ameliorate the intersecting forms of vulnerability and exclusion experienced by the people followed by the author. Yet despite the limitations of a focus on surgery, expanded access to care does create possibilities for trans people to engage in diverse forms of self-transformation. The paradigm of access to gender affirming care through right-to-health litigation circumscribes the possibilities for social transformation within a set of biomedical technologies that come to stand for more radical change. Attending to the diverse forms of care and self-governance that trans people themselves labor to enact offers a more productive register for thinking about the socially transformative potential of the judicialization of health in Brazil.
When Building a Better Vulva, Timing Is Everything
Authors: Mesics Sandra 
Published: May 2018

Abstract
Gender confirmation surgery for the MTF individual has evolved and improved over time, particularly in terms of form and function. While initially surgeons concentrated on creating a vulva that functioned for receptive penetrative intercourse, in time consumer demand and improved surgical techniques have resulted in a vulva that is esthetically pleasing, functional, and sensate. This first-person account shows how techniques evolved in a critical two-year period between 1974 and 1976.
A method for transplantation of human HSCs into zebrafish, to replace humanised murine transplantation models
Authors: Hamilton Noémie , Sabroe Ian , Renshaw Stephen A. 
Published: May 2018

Haematopoietic stem cell (HSC) transplantation is a critical therapy for haematopoietic malignancies and immune disorders. Incomplete or delayed engraftment of HSCs in the host results in increased risk of infection and morbidity. The mechanisms of HSC engraftment are poorly understood and understanding these processes will increase transplantation success on many levels.Current animal models are immunocompromised 'humanised' mice transplanted with human HSCs. Harmful procedures include genetic manipulations and irradiation to ablate the mouse immune system, and opaque mouse tissues make visualisation of the early steps of HSC engraftment impossible. There is a need for new models to offer alternatives to humanised mice in the study of HSC transplantation.Here we described a detailed method for transplantation of human HSCs into zebrafish, before the onset of adaptive immunity. Human HSCs were purified from whole blood by enrichment of the CD34 cell population using a positive magnetic selection and further purified using an anti-CD34 antibody and cell sorting. Sorted CD34 cells were transplanted into the blood stream of 52 hour old zebrafish larvae. Human HSCs home into the zebrafish haematopoietic niche, where they engage with endothelial cells and undergo cell division. Our model offers the opportunities to imagein vivohuman HSC engraftment in a transparent organism, without the myeloablative strategies used in mice, and provides a unique system to understand the dynamic process of engraftment and replace current murine models.This technique can be applied to current engraftment protocols to validate the viability and efficiency of cryofrozen HSC grafts. This humanised zebrafish model will be instrumental to develop the 3Rs values in stem cell transplantation research and our detailed protocol will increase the chances of uptake of this zebrafish model by the mouse community.
Pedagogies of engagement: Using appreciative inquiry to study post-secondary citizenship education
Authors: King Sarah 
Published: May 2018

Abstract
In response to literature documenting the purported disengagement of youth in the civic sphere and the increasing impact of neo-liberal ideologies and policies on the post-secondary education landscape, this article furthers discussion about the civic potential of university education and explores how specific pedagogies can help foster the civic engagement of university students and graduates. Drawing from data collected at Renaissance College (RC), at the University of New Brunswick, this article documents the collaborative and experiential pedagogies used in that programme to support civic learning. Overall, this study demonstrates that the approaches taken at RC are challenging but worthwhile pedagogies that can enhance students’ abilities to become engaged citizens and challenge neo-liberal doctrine at post-secondary institutions. This study also demonstrates how appreciative inquiry (AI) contributes to the development of a methodological framework for studying citizenship education by connecting the epistemological foundations of AI and citizenship education.

Formally equal, but not really: The second stage of an ongoing study into English school students’ perceptions of ‘the citizen’
Authors: Leighton Ralph 
Published: May 2018

Abstract
This article presents a discussion based primarily upon the findings of the second stage of an ongoing research into school students’ perceptions of ‘the citizen’. The first stage was an analysis of images in textbooks intended for GCSE citizenship studies students aged 14–16, the second stage – a year later – involved interviews with A Level citizenship studies students aged 16–18 and with teachers of citizenship. It was found that the images present a particular and unrepresentative image of ‘being British’, a part of which students appear to absorb into their own perceptions, irrespective of their personal experiences. The homogeneity of responses, across class, ethnicity, gender and professional role struck the researcher as notable and similarities and differences are examined. The images represent a highly selective and distorted version of the reality of being English, one that promotes a false consciousness and acceptance of the status quo, uncovering whether or to what extent that version of reality is accepted by those involved is the purpose of this study. Responses in interviews showed that neither the students nor their teachers subscribed to the message behind the images, and that they had their own versions of the reality of ‘the citizen’.
Teacher beliefs about grade repetition: An exploratory South African study
Authors: Walton Elizabeth 
Published: May 2018

Abstract
Inclusive education is described as an ‘apprenticeship in democracy’ as it is concerned with the identification and dismantling of exclusionary practices in schools. One such practice is grade repetition, which is known to result in school disaffection and early school leaving. In South Africa, grade repetition is disproportionately experienced by black and poor learners, resulting in the unequal realization of the democratic right to education. The rate of grade repetition in this country is high, but little is known about teachers’ beliefs about the practice. This article presents the results of a self-administered questionnaire in which Johannesburg teachers described what they regarded as the benefits and drawbacks of grade repetition. The data showed that teachers believe that the additional time spent in a repeated year compensates for immaturity, allows learners to ‘catch up’ and be better prepared for the subsequent grade. Teachers do acknowledge negative emotional and behavioural consequences of grade repetition, but many see no drawbacks to the practice. These beliefs are discussed with reference to the context in which they are engendered, with particular focus on the strong teacher and curriculum control over the pace at which knowledge acquisition is expected. It is argued that addressing the high levels of grade repetition will need critical examination of both the teacher beliefs that sustain the practice and the habits of schools that make failure inevitable for some learners.
Enhancing citizenship learning with international comparative research: Analyses of IEA civic education datasets
Authors: Knowles Ryan T. , Torney-Purta Judith , Barber Carolyn 
Published: May 2018

Abstract
Large-scale international databases provide valuable resources for scholars, educators and policy-makers interested in civic engagement and education in nations that are democracies or striving towards democracy. However, the multidisciplinary nature of secondary analysis of these data has created a fragmentary picture that limits educators’ awareness of relevant findings. We present a summary of research conducted across disciplines using datasets from two large-scale cross-national studies of civic education conducted by the International Association for the Evaluation of Educational Achievement (CIVED:99 and ICCS:09). The IEA studies were conducted in more than 40 countries with nationally representative samples of 14–15 year olds. In a review of over 100 published articles reporting secondary analyses of these data, we identified four themes especially salient for citizenship educators: open classroom climates; teaching and learning approaches; student identity; and profiles of citizenship norms and attitudes. The review summarizes sample relevant articles to illustrate themes, emphasizes connections between education and civic engagement and suggests opportunities for future research.
A Matter of Life and Death: Iron Maiden’s religio-political critique
Authors: Elliott Peter 
Published: May 2018

Abstract
Throughout its history, the musical and lyrical hallmarks of the heavy metal genre have been portrayed as stereotypically dark, despairing and demonic with the most public opposition to its presence in society coming from religious groups who have been all too quick to conflate the aesthetic inspiration of the occult with an actual invocation of it. Through analysing Iron Maiden’s 2006 studio album, A Matter of Life and Death, this religious criticism of heavy metal is turned upside down with the emergence of a dialectical critique of religion as it relates to the political sphere. Through both musical and lyrical analyses, Maiden are shown to address the topics of war and violence in alignment with religious belief and its political out-workings. Intertextuality and sonic indexicality are utilized in the album to issue religio-political statements that bespeak both sensitivity and subversion. Drawing upon Barthes’ ‘death of the author’ concept, readings that display sympathetic resonance with evangelical Christian beliefs are also articulated, challenging the dominant public discourses that tend to situate evangelical Christianity in polar opposition to heavy metal music. The contestable nature of these readings provides a site for questioning political (including religious) interpretations of music epistemologically: Is there a ‘correct’ reading? How do we know which it is? Finally, given present concerns in the public domain over religio-political extremism, some thoughts are offered as to how this heavy metal album provides a framework for engaging with the religio-political mythologies of our age and increasing political censorship.
Constructing black metal mythology for global monopoly: #ittakescourage
Authors: Podoshen Jeffrey S. 
Published: May 2018

Abstract
This article examines the creation of marketplace myths in the realm of the more recent North American ‘black metal’ (quotes deliberate) scene at the hands of a large multinational corporate entity working in tandem with one of the scene’s signature bands. I argue that this collaboration between global media, global fashion and ‘independent’ media has resulted in merely the same corporate co-option of an underground music scene that we have seen time and time again, and that as hard as some artists try, there is no escaping the powers of the marketplace.

Sparse reconstruction with multiple Walsh matrices
Authors: Au-Yeung Enrico 
Published: May 2018

Abstract
The problem of how to find a sparse representation of a signal is an important one in applied and computational harmonic analysis.
It is closely related to the problem of how to reconstruct a sparse vector from its projection in a much lower-dimensional vector space.
This is the setting of compressed sensing, where the projection is given by a matrix with many more columns than rows.
We introduce a class of random matrices that can be used to reconstruct
sparse vectors in this paradigm. These matrices satisfy the restricted isometry property with overwhelming probability. We also discuss an application in dimensionality reduction where we initially discovered this class of matrices.

Published: May 2018

ZusammenfassungDer vorliegende Beitrag geht der Frage nach, wie die aktuellen Wandlungsprozesse rund um das Thema Industrie 4.0 wahrgenommen werden und wovon die Wahrnehmung beeinflusst wird. Im Rahmen der Debatte um das Thema Industrie 4.0 kristallisieren sich drei Trends (Hype,HopeundHarm) heraus, die parallel diskutiert werden. In der vorliegenden Studie werden diese aufgegriffen und mittels einer Online-Befragung mit 136 Mandatsträgern aus dem Bereich der chemisch-pharmazeutischen Industrie empirisch untersucht. Die Studie gibt Hinweise dafür, dass technikaffine Personen das Thema Industrie 4.0 positiver wahrnehmen. Deutlich gezeigt werden kann, dass die Ent- bzw. Belastung durch digitale Technologien die Wahrnehmung von Industrie 4.0 beeinflusst.
Inter-group conflicts in the horn of Africa: The case of Diz and Suri people, Ethiopia
Authors: Tariku Ayele 
Published: May 2018

Abstract
The Horn Africa is the region that consists of Ethiopia, Eretria, Djibouti and Somalia. It is also the region where more than 100 languages are spoken. Besides, it is blessed with natural resources and assumed to be the origin of human beings. Yet, it has remained the scene of various types of conflicts. Of the many areas in the horn of Africa which has been prone to such violent conflict, is the Southwest Ethiopia. This paper attempts to investigate the causes and consequences of the conflict between the Dizi and Suri people. It is in particular stress on addressing the political, social and economic dimension of the conflict, looking first at the administration system, state lead development interventions and economic situations. Evidences were collected from archival sources, field observation and interviews (at six parishes in Maji, Bero and Surma districts) between January and August 2014. It would be factual to argue that the conflict between the Dizi and Suri people in southwest Ethiopia was mainly caused by competition over the natural resources. Until the 1940s, the conflict was merely a local issue which had been mostly resolved through elder’s mediation.
Anecdotal evidence: understanding organizational reality through organizational humorous tales
Authors: Jemielniak Dariusz , Przegalińska Aleksandra , Stasik Agata 
Published: May 2018

AbstractIn the paper, we propose a new focus in qualitative organization studies, which we call organizational anecdotal evidence. The novelty of our method is in linking storytelling, studies of organizational anecdotes, and humor studies. We claim that organizational anecdotes, jokes, and short fictional stories should become a core object of organizational culture analysis, rather than be refuted as unimportant. This is so because the study of organizational anecdotes and fictional stories shared by the social actors is more meaningful and gives more insight into their culture than establishing mere facts. In the article, we briefly relate the limitations of factual studies in many areas of organizational research, describe the theoretical background of our method (coming from humor studies, storytelling, and organizational anecdotes analysis), and propose their combination as a new approach for organization scholars, namely, organizational anecdotal evidence research. The utility of the proposed methodological approach is demonstrated based on original research conducted in a public administration organization.

Abstract
Optical fiber communication is the backbone of the entire telecommunication industries in the world. In this work, the real-time backbone long-distance optical fibers (single mode) are tested and analyzed with two different wavelengths (1,310 nm and 1,550 nm) with the help of optical time domain reflectometer. Using these two different wavelengths, how the losses and events of the backbone optical fibers are changing are compared and analyzed. This work will give a way to study the nature of long-distance backbone optical fiber and understand the real-time application of the fiber optic communication.

Abstract
The prototype of the electric elevator consists of grid power converter connected with three different loads through the adequate power converters [1]. The main objective of this paper is to develop the industrial solution of the regenerative elevator power system, a system containing DC machines, asynchronous three-phase and synchronous with permanent magnets motors. In this paper, only the improvements done on the three-phase power inverter connected to the induction motor will be described. The same improvements can be applied to the three-phase power inverter connected to the synchronous machine. The grid power converter assures the unity power factor operation. The resulted experimental results are shown.
