Finding a reflexive voice : -- researching the problems of implementing new learning practices within a New Zealand manufacturing organisation : a 100pt thesis presented in partial fulfilment of the requirements for the degree of Master of Management in Human Resources Management at Massey University
This study explored the social forces mediating manager's participation in a new reflexive participative learning practice designed to improve profitability within a New Zealand manufacturing organisation. Despite a large theoretical and managerial body of literature on organisational learning there has been little empirical investigation of how people experience and engage their reflexivity towards challenging the status-quo to create high level learning and new knowledge. Power was identified as a potential moderator of the reflexive learning experience and the variable relations of power and learning were constructed from a review of literature and these relationships were explored and investigated within the case study. Two prevailing discourses were identified as powerful moderators of public reflexivity, the traditionalist discourse which constructed managers actions and conversations towards insularism and survivalist concerns and the productionist discourse in which institutionalised production practices encircled and mediated managers actions and what constituted legitimacy in conversations. This study used a critical action research method to place the reflexive experience of managers and the researcher at the centre of the study and provide data representative of the social discourses that constructed variable freedoms and constraints upon the reflexive voice
Don't judge a book by its cover. factitious disorder imposed on children-report on 2 cases
Factitious Disorder Imposed on Another (FDIA), also known as Munchausen Syndrome by Proxy (MSbP) is a very serious form of child abuse. The perpetrator, usually the mother, invents symptoms or causes real ones in order to make her child appear sick. Usually this is due to a maladaptive disorder or to an excessive of attention-seeking on her part. We report here two new cases of FDIA. The first one is a 9-year-old boy with a history of convulsive episodes, reduced verbal production, mild psychomotor disorder and urological problems who underwent several invasive procedures and hospitalizations before a diagnosis of FDIA was made. The second is a 12 year-old girl with headache, abdominal pain, lipothymic episodes, seizures and a gait impairment, who was hospitalized in several hospitals before an FDIA was diagnosed
Beyond Rentiership: Standardisation, Intangibles and Value Capture in Global Production
We examine corporate rentiership in the contemporary economy and suggest that the idea we are in a moment of step-change within capitalism may be premature. Implicit in arguments for a step-change is the claim that the present-day economy emphasises unproductive or rentier forms rather than the more productive and entrepreneurial forms of the past. In contrast, we argue that to understand our current situation we need to focus on the division of labour and most especially on processes of standardisation and the rise of intangible assets. Moving from Marx’s understanding of rent as a class relation, we re-embed rent within the circuit of capital and the realm of value distribution to investigate the class dynamics (among labour, capital and the state) through which giant firms seem to generate value out of rentierism. We argue that these class dynamics include the crucial and unexplored relation between standardisation and intangibles. We suggest standardisation within the division of labour renders people, places, and things interchangeable and that, in contrast, intangible assets differentiate them. When intangible assets emerge as new forms of property, they enable owners to generate scarcity and exert direct and/or indirect control over the wider division of labour. Through examining the combined rise of standardisation and intangible assets within the technical division of labour, we demonstrate how hierarchy within the social division of labour empowers some corporations to capture value produced elsewhere within the circuit of capital
Adverse Mental Health Impact of the COVID-19 Lockdown in Individuals With Tourette Syndrome in Italy: An Online Survey
During the early stages of the coronavirus disease 2019 (COVID-19) pandemic in Italy, an online survey was launched via a local patient advocacy website to investigate mental health issues in children and adolescents with Tourette syndrome (TS). Respondents were parents, who were asked to report on their child's general health, tics, comorbidities/problems, pharmacological treatment/psychotherapy, symptom variations, and daily routine, as well as on their family's health and work experiences during the pandemic. Two hundred thirty-eight people participated in the survey, 203 females and 35 males. Our findings indicate that, in the time window of 4–6 weeks after the beginning of the COVID-19-related lockdown, 67% of individuals with TS developed a relevant worsening of the overall clinical condition as rated by their parents. An improvement or no variation of the clinical picture was reported in 20.5 and 6.7% of cases, respectively. Most worsened symptoms included tics, hyperactivity, rage attacks, obsessions/compulsions, and anxiety. Of the subjects experiencing a clinical worsening, the majority (51.76%) showed variations across two to five symptom domains. No association was found between symptom variation and family demographics or health and economic issues specifically related to the lockdown. The current COVID-19 pandemic is exerting a considerable impact on the mental health of young individuals with TS by worsening both tics and emotional and behavioral symptoms
Nanomaterials for the cleaning and pH adjustment of vegetable tanned leather
Leather artifacts in historical collections and archives are often contaminated by physical changes such as soiling, which alter their appearance and readability, and by chemical changes which occur on ageing and give rise to excessive proportion of acids that promote hydrolysis of collagen, eventually leading to gelatinization and loss of mechanical properties. However, both cleaning and pH adjustment of vegetable tanned leather pose a great challenge for conservators, owing to the sensitivity of these materials to the action of solvents, especially water-based formulations and alkaline chemicals. In this study the cleaning of historical leather samples was optimized by confining an oil-in-water (o/w) nanostructured fluid in a highly retentive chemical hydrogel, which allows the controlled release of the cleaning fluid on sensitive surfaces. The chemical gel exhibits optimal viscoelasticity, which facilitates its removal after the application without leaving residues on the object. Nanoparticles of calcium hydroxide and lactate, dispersed in 2-propanol, were used to adjust the pH up to the natural value of leather, preventing too high alkalinity which causes swelling of fibers and denaturation of the collagen. The treated samples were characterized using Scanning Electron Microscopy (FE SEM), controlled environment dynamic mechanical analysis (DMA-RH), and infrared spectroscopy (ATR-FTIR). The analytical assessment validated the use of tools derived from colloid and materials science for the preservation of collagen-based artifacts
Percolation phenomena of calcium bis(2-ethylhexyl) sulfosuccinate water - in - oil microemulsions by dielectric spectroscopy
Two-phase water model in the cellulose network of paper
Water diffusion in cellulose was studied via two-phase Karger model and the propagator method. In addition to ruling out anomalous diffusion, the mean squared displacements obtained at different diffusion times from the Karger model allowed to characterize the system's phases by their average confining sizes, average connectivity and average apparent diffusion coefficients. The two-phase scheme was confirmed by the propagator method, which has given insights into the confining phase-geometry, found consistent with a parallel-plane arrangement. Final results indicate that water in cellulose is confined in two different types of amorphous domains, one placed at fiber surfaces, the other at fiber cores. This picture fully corresponds to the phenomenological categories so far used to identify water in cellulose fibers, namely, free and bound water, or freezing and non-freezing water
