Understanding manager resistance to blockchain systems

Blockchain technology has received much attention in the media and there is an increasing interest amongst organizations within financial services due to the potential benefits. As blockchain-based systems are a nascent technology, the requirements of the technology need to be understood, to allow blockchain systems to be successfully integrated within financial service organizations. There are gaps in academic research in understanding how managers evaluate the value of a blockchain-based system. This study develops a model to explain manager resistance to implementing blockchain-based systems in financial services organizations. This research advances the theoretical understanding of managers’ perspectives on blockchain-based systems and models their resistance to blockchain technology.

Procedural (in)justice,emotions, and compliance

The procedural justice model has become widely recognized as a key crime prevention and reduction strategy, spurring its adoption across police agencies throughout the United States in an effort to address mounting concerns regarding police use of force. Recent critiques, however, have called attention to the need for greater examination of potential contributing factors that are underdeveloped in investigations of the procedural justice model, including the role of emotions. This article takes stock of interdisciplinary advancements to critically examine scholarly investigations exploring associations between procedural (in)justice, emotions, and compliance behaviors within the context of police-citizen interactions. In doing so, continued gaps are identified. Lastly, this article concludes by identifying future pathways and recommendations for the scholarly advancement of our understanding of emotions and their continued relevance to the procedural justice model.     

矿渣MTC胶结物抗腐蚀性能研究

随着矿渣MTC技术的发展和应用,矿渣MTC胶结物的抗腐蚀性能日益受到人们的关注。矿渣MTC胶结物的抗腐蚀性能直接关系到矿渣胶结物后期性能,并影响井和套管的使用寿命。分析了矿渣MTC胶结物可能受到的几种腐蚀类型及其机理,实验验证了矿渣胶结物具有较强的抗NaCl、Na₂CO₃、Na₂SO₄、MgSO₄侵蚀的能力,但易受酸性介质腐蚀;实验发现了加入胶乳能较大幅度提高矿渣胶结物抗酸性介质腐蚀的能力,并对胶乳提高矿渣胶结物抗酸蚀能力的原因进行了分析。     

COMMENTARY (12 YEARS ON) ON ‘THE CONTRIBUTION OF OBSERVATION TRAINING TO PROFESSIONAL DEVELOPMENT IN SOCIAL WORK’ BY JUDITH TROWELL AND GILLIAN MILES

This article aims to stimulate discussion about relationships between the lives of professionals and of service users. The idea is that when parallels are explored and developed, power dynamics between professionals and social workers are reduced, the quality of interaction and work with service users can be improved, and professionals can also be helped in overcoming difficulties in their own lives. I start with an outline of my own personal background and highlight my development throughout, including my emerging identity as a Buddhist. I discuss a case study involving ‘Sally’ and her family and our work together while I was a social work assistant in a Children and Family's team. I try to show the interconnections between the different difficulties that we faced and how that informed my work. I look at some of the benefits, pitfalls and boundaries of working from the point of view that service user and professional are both working to overcome their problems. I also interweave interactions I had at the time with Carlos, a drug user friend in a crisis and the impact he had on me. Because I include my own situation I have called this article a ‘case experience’.

Throughout I refer to Buddhist and psychoanalytic thinking and particularly to agreement between the two around ideas that inner‐resistance is the main barrier to personal evolution. I argue that faith is the key to unlocking resistance, and that faith should be understood as the development of a belief within people that they are able to progress rather than be destroyed in the face of inevitable problems.

Human Health Risk Assessment of Penicillin/Aminopenicillin Resistance in Enterococci Due to Penicillin Use in Food Animals

Penicillin and ampicillin drugs are approved for use in food animals in the United States to treat, control, and prevent diseases, and penicillin is approved for use to improve growth rates in pigs and poultry. This article considers the possibility that such uses might increase the incidence of ampicillin-resistant Enterococcus faecium (AREF) of animal origin in human infections, leading to increased hospitalization and mortality due to reduced response to ampicillin or penicillin. We assess the risks from continued use of penicillin-based drugs in food animals in the United States, using several assumptions to overcome current scientific uncertainties and data gaps. Multiplying the total at-risk population of intensive care unit (ICU) patients by a series of estimated factors suggests that not more than 0.04 excess mortalities per year (under conservative assumptions) to 0.14 excess mortalities per year (under very conservative assumptions) might be prevented in the whole U.S. population if current use of penicillin drugs in food animals were discontinued and if this successfully reduced the prevalence of AREF infections among ICU patients. These calculations suggest that current penicillin usage in food animals in the United States presents very low (possibly zero) human health risks.     

The event of death: Reflections on the dynamics of emotions and embodied resistance in the Moroccan Contexts of hirak (movement) and la hirak ((non)movement)

This paper studies the role of emotions in creating spectacular revolt situations. We underline the travelling competence of sentiments and their power in crafting trans-local moments of embodied resistance. In contemporary Moroccan society, the adaptation of the Bouazizian style of protest has been a reaction to the prevailing feelings of worthlessness gripping the common citizen. The images of wasted beings in the post-2011 atmosphere have been associated with instances of social insurgence, by individuals who attempt self-immolation, or citizens treated by figures from the centre (e.g. police, public figures) in a way that inculcate in them powerful feelings of abjection, after which they feel irreparably delinked from their sense of humanity. This paper seeks to demonstrate how practices of al-hogra (humiliation) have produced cultural forms of abjection that could also be traced in the way common people inferiorize one another in everyday life through the use of a terminology of trash. By disclosing people’s non-subtle armaments of protest (i.e. self-immolation), we contend that resistance and its various trances, as well as the emotions that prompt them, have their origin in the reality of the body, realistic visions of the body owner and his/her awareness of the potential for realization (through it). Hence we will examine how vulnerable people manipulate the three conditions of corporeality, corporealism and corporealization, to subvert the humiliation and symptoms of social death imposed on them by the regime.     

The impact of testosterone replacement therapy on glycemic control,vascular function,and components of the metabolic syndrome in obese hypogonadal men with type 2 diabetes

Objective: This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2).

Study design: Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n?=?28) was treated with testosterone undecanoate (1000?mg i.m. every 10?weeks) while group P (n?=?27) received placebo.

Methods: Anthropometrical and vascular measurements – flow-mediated dilatation (FMD) and intima media thickness (IMT) – biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated.

Results: TRT resulted in reduction of HOMA-IR by 4.64?±?4.25 (p?p?p?=?.005).

Conclusion: TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population.
