Teaching critical reflection: a tool for transformative learning in social work?

In an Australian Bachelor of Social Work degree, critical reflection is a process explicitly taught in a fourth year subject to students who have returned from their first field placement experience in agencies delivering social work programmes. The purpose of teaching critical reflection is to enable social work students to become autonomous and critical thinkers who can reflect on society, the role of social work and social work practices. The way critical reflection is taught in this fourth year social work unit relates closely to the aims of transformative learning. Transformative learning aims to assist students to become autonomous thinkers. Specifically, the critical reflection process taught in this subject aims to assist students to recognise their own and other people's frames of reference, to identify the dominant discourses circulating in making sense of their experience, to problematise their taken-for -granted ‘lived experience’, to reconceptualise identity categories, disrupt assumed causal relations and to reflect on how power relations are operating. Critical reflection often draws on many theoretical frameworks to enable the recognition of current modes of thinking and doing. In this paper, we will draw primarily on how post-structural theories, specifically Foucault's theorising, disrupt several taken-for-granted concepts in social work.

Effects of work-related sleep restriction on acute physiological and psychological stress responses and their interactions: A review among emergency service personnel

Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel) that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological responses. Furthermore, it investigated if a psycho-physiological approach can help contextualize the significance of such responses to assist emergency service agencies monitor the health of their personnel. The available literature suggests that sleep restriction across multiple work days can disrupt cytokine and cortisol levels, deteriorate mood and elicit simultaneous physiological and psychological responses. However, research concerning the interaction between such responses is limited and inconclusive. Therefore, it is unknown if a psycho-physiological relationship exists and as a result, it is currently not feasible for agencies to monitor sleep restriction related stress based on psycho- physiological interactions. Sleep restriction does however, appear to be a major stressor contributing to physiological and psychological responses and thus, warrants further investigation.

Acute psychophysiological relationships between mood, inflammatory and cortisol changes in response to simulated physical firefighting work and sleep restriction

This study examined how changes in wildland firefighters' mood relate to cytokine and cortisol levels in response to simulated physical firefighting work and sleep restriction. Firefighters completed 3 days of simulated wildfire suppression work separated by an 8-h (control condition; n = 18) or 4-h sleep opportunity (sleep restriction condition; n = 17) each night. Firefighters' mood was assessed daily using the Mood Scale II and Samn-Perelli fatigue scale. Participants also provided samples for the determination of salivary cortisol and pro- (IL-6, IL-8, IL-1β, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokine levels. An increase in the positive mood dimension Happiness was related to a rise in IL-8 and TNF-α in the sleep restriction condition. A rise in the positive mood dimension Activation among sleep restricted firefighters was also related to higher IL-6 levels. An increase in the negative mood dimension Fatigue in the sleep restriction condition was associated with increased IL-6, TNF-α, IL-10 and cortisol levels. In addition, an increase in Fear among sleep restricted firefighters was associated with a rise in TNF-α. Elevated positive mood and immune activation may reflect an appropriate response by the firefighters to these stressors. To further understand this relationship, subsequent firefighting-based research is needed that investigates whether immune changes are a function of affective arousal linked to the expression of positive moods. Positive associations between negative mood and inflammatory and cortisol levels to physical work and restricted sleep provide useful information to fire agencies about subjective fire-ground indicators of physiological changes.

The work-based predictors of job engagement and job satisfaction experienced by community health professionals

Background: Job engagement represents a critical resource for community-based health care agencies to achieve high levels of effectiveness. However, studies examining the organisational sources of job engagement among health care professionals have generally overlooked those workers based in community settings.
Purpose: This study drew on the demand-control model, in addition to stressors that are more specific to community health services (e.g., unrewarding management practices), to identify conditions that are closely associated with the engagement experienced by a community health workforce. Job satisfaction was also included as a way of assessing how the predictors of job engagement differ from those associated with other job attitudes.
Methodology/Approach: Health and allied health care professionals (n = 516) from two
Australian community health services took part in the current investigation. Responses from the two organisations were pooled and analysed using linear multiple regression.
Findings: The analyses revealed that three working conditions were predictive of both job engagement and job satisfaction (i.e., job control, quantitative demands and unrewarding management practices). There was some evidence of differential effects with cognitive demands being associated with job engagement, but not job satisfaction.
Practice Implications: The results provide important insights into the working conditions that, if addressed, could play key roles in building a more engaged and satisfied community health workforce. Further, working conditions like job control and management practices are amenable to change and thus represent important areas where community health services could enhance the energetic and motivational resources of their employees.

On-call work: to sleep or not to sleep? It depends

On-call working time arrangements are increasingly common, involve work only in the event of an unpredictable incident and exist primarily outside of standard hours. Like other non-standard working time arrangements, on-call work disrupts sleep and can therefore have negative effects on health, safety and performance. Unlike other non-standard working time arrangements, on-call work often allows sleep opportunities between calls. Any sleep obtained during on-call periods will be beneficial for waking performance. However, there is evidence that sleep while on call may be of substantially reduced restorative value because of the expectation of receiving the call and apprehension about missing the call. In turn, waking from sleep to respond to a call may be associated with temporary increases in performance impairment. This is dependent on characteristics of both the preceding sleep, the tasks required upon waking and the availability and utility of any countermeasures to support the transition from sleep to wake. In this paper, we critically evaluate the evidence both for and against sleeping during on-call periods and conclude that some sleep, even if it is of reduced quality and broken by repeated calls, is a good strategy. We also note, however, that organisations utilising on-call working time arrangements need to systematically manage the likelihood that on-call sleep can be associated with temporary performance impairments upon waking. Given that the majority of work in this area has been laboratory-based, there is a significant need for field-based investigations of the magnitude of sleep inertia, in addition to the utility of sleep inertia countermeasures. Field studies should include working with subject matter experts to identify the real-world impacts of changes in performance associated with sleeping, or not sleeping, whilst on call.

O ambiente de trabalho no setor bancário e o bem-estar

Wich the big transformations at the world of labor, thus as the appearing of the negatives psicologicals consequencies? Publications in books and articles about the health of the workers have been seen in the last 40 years, pointing at the increase of occupational ills, increase of the absenteeism, reach the redation between the labor and the family. With the appearing of the neoliberal sistem, changed all the net of relations, thus as the temporary labor contract, the flexibility at the work timetable, and others, that privilege the capitalism, in detriment of the worker health. It was given emphasis to the banking worker, in time that the banks and the banking agencies were one of the departaments that more suffered the impact of the productive restructuring at the last years. 200 bank clerks shared the search, in that 41,9% was female and 58,1% was male, 60,9% presenting a civil state married, following of 28,4% of single. The participants answered the following instruments: Scale of Positives and Negative Kindness, General Health Questionaire GHQ 12, Scale of Organization, Conditions and Labor Relations, Scale of Desire (own authorship), Scale about economic situation and a social-demographic record car. With the objective of trying the instruments of measure, it was checking the psychometric parameter of the search scales. We could verify that it has been more positive than negative ones for the mental health, but it was found some kind of depression and unsatisfied with their lives in some pieces of the sample. We can finally say that the work place has an impact at the mental health of the bank clerks. So, some interventions actions to promote the worker health could be essential

Time analysis for temporary gravitational capture - Stable orbits

In a previous work, Vieira Neto & Winter (2001) numerically explored the capture times of particles as temporary satellites of Uranus. The study was made in the framework of the spatial, circular, restricted three-body problem. Regions of the initial condition space whose trajectories are apparently stable were determined. The criterion adopted was that the trajectories do not escape from the planet during an integration of 10(5) years. These regions occur for a wide range of orbital initial inclinations (i). In the present work it is studied the reason for the existence of such stable regions. The stability of the planar retrograde trajectories is due to a family of simple periodic orbits and the associated quasi-periodic orbits that oscillate around them. These planar stable orbits had already been studied (Henon 1970; Huang & Innanen 1983). Their results are reviewed using Poincare surface of sections. The stable non-planar retrograde trajectories, 110 degrees less than or equal to i < 180, are found to be tridimensional quasi-periodic orbits around the same family of periodic orbits found for the planar case (i = 180 degrees). It was not found any periodic orbit out of the plane associated to such quasi-periodic orbits. The largest region of stable prograde trajectories occurs at i = 60 degrees. Trajectories in such region are found to behave as quasi-periodic orbits evolving similarly to the stable retrograde trajectories that occurs at i = 120 degrees.

Draft programme of regional statistical work for Latin America and the Caribbean, July 2005-June 2007

Includes bibliography

Report on the implementation of the ECLAC work programme subregional activities for the Caribbean 2006-2007 biennium [Covering the period 1 Janurary 2006- 31 December 2007]

The focus of the activities of the Economic Commission for Latin America and the Caribbean/Caribbean Development and Cooperation Committee (ECLAC/CDCC) secretariat during the 2006-2007 biennium continued to be on assistance to member governments of the subregion with policy-making and development strategies, especially on issues relevant to the promotion of the economic, social, and environmental dimensions of development in the Caribbean. The Subregional Headquarters for the Caribbean worked closely with member countries of the CDCC in an effort to ensure the relevance of outputs which would inform policy options. This involved the strengthening of partnerships with both regional and subregional institutions and relevant agencies of the United Nations system working in the Caribbean. A major decision was taken to refocus the operational aspects of the secretariat to ensure that they were relevant to the development goals of its members. This involved the introduction of a thematic approach to the work of the office. One of the changes resulting from this was the restructuring and renaming of the Caribbean Documentation Centre. The Caribbean Knowledge Management Centre (CKMC), as it is now known, has changed its emphasis from organizing and disseminating documents, and is now a more proactive partner in the research undertaken by staff and other users of the service. The CKMC manages the ECLAC website, the public face of the organization. Newsletters and all other documents, including Information and Communications Technology (ICT) profiles of selected countries, prepared by the secretariat, are now available online at the ECLAC/CDCC website www.eclacpos.org . The Caribbean Knowledge Management Portal was launched at a meeting of information specialists in St. Vincent and the Grenadines in 2007. In addition to reaching a wider public, this measure was introduced as a means of reducing the cost of printing or disseminating publications. In spite of the unusually high vacancy rate, at both the international and local levels, during the biennium, the subregional headquarters accomplished 98 per cent of the 119 outputs earmarked for the period. Using vacant positions to carry out the assignments was not an easy task, given the complexity in recruiting qualified and experienced persons for short periods. Nevertheless, consultancy services and short-term replacement staff greatly aided the delivery of these outputs. All the same, 35 work months remained unused during the biennium, leaving 301 work months to complete the outputs. In addition to the unoccupied positions, the work of the subprogramme was severely affected by the rising cost of regional and subregional travel which limited the ability of staff to network and interact with colleagues of member countries. This also hampered the outreach programme carried out mainly through ad hoc expert group meetings. In spite of these shortcomings, the period proved to be successful for the subprogramme as it engaged the attention of member countries in its work either through direct or indirect participation. Staff members completed 36 technical papers plus the reports of the meetings and workshops. A total of 523 persons, representing member countries, participated in the 18 intergovernmental and expert meetings convened by the secretariat in the 24-month period. In its effort to build technical capacity, the subprogramme convened 15 workshops/seminars which offered training for 446 persons.

Air accident investigation among regulatory agencies

The aim of this manuscript is to describe and compare regulatory aviation agencies according to their subordination and attributions to investigate air accidents. Possible consequences in identifying the contributory factors are also presented. Distinct procedures investigating air accidents among agencies lead to a lack of standardization of the statistics, making it difficult to analyze the data globally. Separately the information does not configure the entire scenario of what occurred, affecting the analysis and subsequent interventions. We recommend a joint and collaborative work between the different committees that operate in the investigation of air accidents.

Parathyroid adenoma apoplexy as a temporary solution of primary hyperparathyroidism: a case report

Abstract Introduction The natural history of patients with spontaneous parathyroid necrosis is unknown. In this case report we describe the clinical course, laboratory, radiographic, bone densitometry tests, parathyroid ultrasonography and scintigraphy examinations of a patient performed over a period of eight years after she first presented with a sudden episode of spontaneous resolution of primary hyperparathyroidism (PHPT). Case presentation A 24-year-old woman with a clinical history and laboratory and radiographic tests compatible with PHPT suffered a sudden episode of cervical pain and presented with clinical evidence of hypocalcemia. Biopsy of a cervical nodule revealed necrotic material compatible with ischemia of the parathyroid. The follow-up of the patient presented four distinct phases: the first, which lasted two years, was compatible with a period of bone hunger during which it was necessary to introduce calcitriol and calcium carbonate. During this period, the patient showed bone mass gain. The second phase was characterized by normalization of calcium and parathyroid hormone levels and its end was difficult to define. During the third phase there was a recurrence of hypercalcemia associated with elevated parathyroid hormone (PTH) levels and loss of bone mass. The last phase corresponded to the interval after parathyroidectomy, which was characterized by normalization of serum levels of calcium and PTH, as well as bone mass gain. Conclusion This case report indicates that spontaneous resolution of PHPT by adenoma necrosis is potentially temporary. Thus, in cases in which a conservative approach is chosen, clinical and laboratory follow-up is indispensable. Bone mass measurement is a useful tool in the follow-up of these cases. However, this option exposes the patient to a potential roller-coaster ride of bone mass gain and loss, whose long term consequences are still unknown.
