Campos-Fernández, Maria del Mar;Ponce-de-León-Rosales, Samuel;Archer-Dubon, Carla;Orozco-Topete, Rocío;
Revista de investigación clínica , 2005,
Abstract: objective. to evaluate the incidence of adverse cutaneous drug reactions in intensive care unit patients. design. cohort study. setting. general adult intensive care unit of an institutional tertiary care hospital. patients. patients in the intensive care unit during a consecutive 8-month period were examined for adverse cutaneous drug reactions. results. patients in the intensive care unit have an incidence of 11.6% of adverse cutaneous drug reactions. associated risk factors were female gender, obesity, age over 60 and immune dysregulation (systemic lupus erythematosus, dysthyroidism, and antiphospholipid antibodies syndrome). few patients had previous history of adverse cutaneous drug reactions. antimicrobials were the main drug involved. morbilliform rash followed by urticary were the most frequently observed reactions. interestingly, over 50% of patients with massive edema -independent of etiology- died. conclusions. intensive care unit patients are particularly at risk for developing an adverse cutaneous drug reaction.
When Reaching Our Potential Predicts Low Values: A Longitudinal Study about Performance and Organizational Values at Call Centres  [PDF]
Danilo Garcia, Trevor Archer
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.54037
Abstract: The present study was executed using data from a call centre in Sweden in which agents answered questions regarding financial advice. The aim of the study was to investigate the relationship of call centre agents’ perceptions about the work climate and the organizational values to their performance, as measured by the organization. In Study 1, agents (N = 106) reported their experience about the work climate and organizational values. Performance (i.e., percent of time on the phone for each work day) was then assessed for the next six consecutive months. In Study 2, agents’ perceptions of organizational values were measured among a new sample (N = 262) from the same call centre. Performance was measured during the next two consecutive years. With regard to the working climate, workers’ autonomy was negatively related to their own performance. The results show also a negative relationship between organizational values and performance during the two following years. Agents seem to maintain high productivity levels at the cost of organizational core values, perhaps due to the visible and rewarding nature of productivity.
Depressive Expression and Anti-Depressive Protection in Adolescence: Stress, Positive Affect, Motivation and Self-Efficacy  [PDF]
Mats Lindahl, Trevor Archer
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.46070

The present study aims at identifying predisposing and protective factors for the purpose of showing their respective contribution and interaction for adolescents’ stress disorders and depressive states, and to find key attributes for the identification of pupils at risk in a normal population of adolescents. The study was performed with 211 high-school pupils over a period of 18 months. The results are reported from the pupils participating in 4 consecutive administrations of the instruments (N = 115). The following instruments were used: “Kutcher Adolescent Depression Scale”, “Stress”, “Helplessness”, “Hopelessness”, “Uppsala Sleep inventory”, “Barratt’s Impulsiveness Scale”, “Positive Affect and Negative Affect Scale”, “Life Orientation Test”, “General Self-Efficacy”, “Locus of Control”, “Situational Intrinsic Motivational Scale”. The Positive Affect and Negative Affect Scale were also used to categorize participants into four affective profiles: “self-fulfilling”, high affective”, “low affective” and “self-destructive”. Linear regression analyses showed that situational depression (hopelessness) was predicted by depressive. Negative affect predicted stress, which in turn predicted general and situational depressiveness. General self-efficacy, positive affect and Identified regulation were found to be protective factors to both general and situational depressiveness. Depressiveness was found to be linked to the “self-destructive” affective personality type. “Negative affect” and distractiveness are suggested as markers for pupils at risk, whereas positive affect, self-efficacy and identified regulation appear to have protecting roles.

Exercise and Dietary Restriction for Promotion of Neurohealth Benefits  [PDF]
Trevor Archer, Danilo Garcia
Health (Health) , 2015, DOI: 10.4236/health.2015.71016
Abstract: Physical exercise, whether aerobic, endurance or resistance types, plays a central role in establishing and maintaining the integrity of the brain and central nervous system (CNS). When exercise is adhered to in conjunction with selective food/drink intake and dietary restriction, it promotes neurohealth. In this article, we review the interactions of age and gender, as well as insulin and diabetes, with exercise, individuals’ cognitive-affective status and its interactions with exercise propensity, all of which modulate the eventual outcomes of the influence of exercise upon parameters of neurohealth. The combination of exercise with dietary restriction provides numerous factors pertaining to psychological, neurochemical and anti-pathological manifestations of neu-rophysiological resilience even through aging. The challenge evoked by the exercise-diet combination in the body mobilizes a multitude of adaptive cellular stress-response signaling pathways in neurons involving neurotrophic factors, anti-inflammatory cytokines, DNA-repair proteins, macroautophagy, and mitochondrial biogenesis.
Influence of Resident Education in Correctly Diagnosing Extremity Soft Tissue Sarcoma

Sarcoma , 2013, DOI: 10.1155/2013/679323
Abstract: Background. One-third of all extremity soft tissue sarcomas are misdiagnosed and inappropriately excised without proper preoperative diagnosis and planning. This study aimed at examining the clinical judgment of residents in both general and orthopaedic surgery and at determining whether resident education plays a role in appropriately managing unknown soft tissue masses. Methods. A case-based survey was used to assess clinical decisions, practice patterns, and demographics. Aggregate response for all of the clinical cases by each respondent was correlated with the selections made for practice patterns and demographic data. Results. A total of 381 responses were returned. A higher percentage of respondents from the orthopaedic group (84.2%) noted having a dedicated STS rotation as compared to the general surgery group (35.8%) . Depth, size, and location of the mass, rate of growth, and imaging characteristics were considered to be important factors. Each additional year of training resulted in 10% increased odds of selecting the correct clinical decision for both groups. Conclusion. Our study showed that current residents in both orthopaedic surgery and general surgery are able to appropriately identify patients with suspicious masses. Continuing education in sarcoma care should be implemented beyond the years of residency training. 1. Introduction Soft tissue sarcomas (STS) are highly malignant and rare tumors with an incidence of about 1 in every 100,000 patients [1]. In contrast, their benign counterparts are much more common with an incidence of about 300 in every 100,000 patients [2]. The relatively high incidence of benign soft tissue neoplasms as compared to malignant STS results in many incomplete excisions of STS without adequate preoperative planning, biopsy, and imaging. At our institution, approximately two-third of patients present for a primary resection while the remaining one-third present for a re-resection of an incompletely excised tumor. These unplanned excisions often leave positive surgical margins and necessitate a much larger repeat excision to obtain clear surgical margins. This subsequently results in greater emotional tolls, higher costs, and inferior functional outcomes [3]. While it is well established that STS are often mistakenly excised under the pretense of a benign tumor, it is not completely known how the physician’s graduate medical education training plays a role in this. In an attempt to understand this further, we administered a case-based sarcoma survey that assessed the respondent is clinical decision making

Improving undergraduate clinical supervision in a South African context
E Archer
African Journal of Health Professions Education , 2011,
Abstract: Objectives: The Faculty of Health Sciences, Stellenbosch University, has undergraduate programmes for several disciplines; these programmes need clinical supervisors to teach their students in the clinical settings. The faculty does not have the resources to present different clinical supervisioncourses for each discipline; therefore a short course with an interprofessional focus was designed. Design: A qualitative study was done to determine the strengths and weaknesses of the course in order to re-curriculate as deemed necessary. Semi-structured individual interviews were held with 10 (n=18) course participants as well as the tutors involved in the development of the course. Ethical approval was obtained. Participation was voluntary and anonymity was guaranteed. The recorded and transcribed data were analysed. Setting: The health professionals acting as supervisors may be the experts in their fields, but they do not always have the necessary teaching skills. The Centre for Health Sciences Education (CHSE) at the faculty has developed a generic short course in undergraduate clinical supervision to address the above issue. Results and conclusion: The data were used to inform restructuring of the short course for the following year. The impact of this short course on clinical supervisors was that their interaction with students in the clinical setting improved. There was unanimous support for extending the short course to all clinical supervisors. The lecturers involved in developing the course were positive about the interprofessional cooperation among colleagues and students. They emphasised that the Faculty of Health Sciences has an obligation to provide opportunities for clinical supervisors to improve their skills to supervise students.
Methane hydrate stability and anthropogenic climate change
D. Archer
Biogeosciences (BG) & Discussions (BGD) , 2007,
Abstract: Methane frozen into hydrate makes up a large reservoir of potentially volatile carbon below the sea floor and associated with permafrost soils. This reservoir intuitively seems precarious, because hydrate ice floats in water, and melts at Earth surface conditions. The hydrate reservoir is so large that if 10% of the methane were released to the atmosphere within a few years, it would have an impact on the Earth's radiation budget equivalent to a factor of 10 increase in atmospheric CO2. Hydrates are releasing methane to the atmosphere today in response to anthropogenic warming, for example along the Arctic coastline of Siberia. However most of the hydrates are located at depths in soils and ocean sediments where anthropogenic warming and any possible methane release will take place over time scales of millennia. Individual catastrophic releases like landslides and pockmark explosions are too small to reach a sizable fraction of the hydrates. The carbon isotopic excursion at the end of the Paleocene has been interpreted as the release of thousands of Gton C, possibly from hydrates, but the time scale of the release appears to have been thousands of years, chronic rather than catastrophic. The potential climate impact in the coming century from hydrate methane release is speculative but could be comparable to climate feedbacks from the terrestrial biosphere and from peat, significant but not catastrophic. On geologic timescales, it is conceivable that hydrates could release as much carbon to the atmosphere/ocean system as we do by fossil fuel combustion.
24 X 7: The Sunderland Experience
Julie Archer
Liber Quarterly : The Journal of European Research Libraries , 2004,
Abstract: The University of Sunderland is committed to widening participation. This means we attract a wide range of students from the non-traditional higher education sector, and an increasing population of international students. The need to support and develop these students' study skills is important and the libraries are seen as central to the strategy in providing both quality learning environments and resources. We are aware of factors such as almost 90% of our students also have part time jobs; increasingly our students can be based in a partner college or are distance learners. Our commitment to learners should be proactive, in providing a quality-learning environment when they need it regardless of their personal life styles and commitments. The need to provide flexible access is vital and was an important planning factor when looking at our service provision and developing the buildings. Libraries also have an important role in supporting student recruitment and retention. To be customer focused we need to recognise students' pastoral needs where they affect their learning needs, and in the case of international students this may include making provision for real time contact with their families. Meanwhile the University is developing a two-campus profile, having been for many years spread throughout the city. The libraries are seen as focus points for study places, print and electronic resources.
