The touristic transformation of postcolonial states: human zoos, global tourism competition, and the emergence of zoo-managing states

Tourism is transforming states. Nevertheless, how, in what ways, and with what consequences has yet to be adequately theorised and interrogated. This paper takes up this task by asking: How does tourism govern and transform states? And, what does this mean for places and people? Tourism is a global mobilities system with immense power. While this system is capable of governing and transforming all states, it has particular resonance in postcolonial states. Due to their historically constructed economic dependency on international tourism, postcolonial states are increasingly conceptualising, representing, and governing their territory/citizenry as desirable/safe ‘tourism destinations’ and ‘touristic figures’ for international—primarily white Western—tourists. This, we argue, is indicative of postcolonial states enacting a mode of governance that harks back to the colonial practice of human zoos and, thus, that they are acting as competitive ‘zoo-managers’. Through theorising and interrogating this touristic state transformation we reveal the continued coloniality of postcolonial states and how this is being experienced, negotiated, and resisted by citizens

ELSI guidelines for networked collaboration and information exchange in PPDR and risk governance

Networked collaboration and information exchange technologies have transformative potential for PPDR and risk governance. However, it is difficult to shape these transformations in a way that supports real world practices of collaboration and sense-making, and it is even more difficult to do so in ways that are ethically, legally and socially sensitive and proactive. This paper presents efforts to construct Ethical, Legal and Social Issues or ‘ELSI’ Guidelines for Networked Collaboration and Information Exchange in PPDR. The Guidelines would facilitate Risk Governance and serve as a living community resource to support the design and use of IT for PPDR and Risk Governanc

Low forced expiratory volume is associated with blunted cardiac reactions to acute psychological stress in a community sample of middle-aged men and women

It has been argued recently that blunted cardiovascular reactions to acute psychological stress have adverse behavioural and health corollaries that reflect dysregulation of the neural systems that support motivation. We examined the association between cardiovascular reactions to a standard stress task, the paced auditory serial arithmetic rest, and forced expiratory volume in one second, an effort, hence motivation, dependent assessment of lung function measured by spirometry. Low forced expiratory volume, expressed as a ratio to height squared was associated with blunted heart rate, but not blood pressure, stress reactivity, r = .17, p < .001. The association survived adjustment for smoking, a range of anthropometric and sociodemographic covariates, resting heart rate and stress task performance, β = .11, p = .005. As such, our results provide support for the hypothesis that blunted stress reactivity may be a peripheral marker of a dysfunction in the brain systems that support motivated behaviour

Assessment of the Physicochemical Properties of Chrysotile-Containing Brake Debris Pertaining to Toxicity

Grinding and drilling of chrysotile asbestos-containing brake pads during the 20thcentury led torelease of chrysotile, resulting in varying levels of workplace exposures of mechanics. Despite expo-sures, excess risk of mesothelioma remains in doubt.Objectives:The toxicity of particulates is primarily derived through a combination of physicochemicalproperties and dose and as such this study aimed to determine properties of asbestos-containingbrake debris (BD) which may influence pathogenicity and potential of mesothelioma.Materials and Methods:Chrysotile-containing brake pads were ground–to reflect occupational activ-ities, aerosolized, and size-fractionated to isolate respirable fractions. Analysis of morphology, biodur-ability, surface charge, and interactions with macrophages were undertaken.Results:The respirable fraction of BD contained15–17% free chrysotile fibers thereby constituting asmall but relevant potential long fiber dose. Acellular biodurability studies showed rapid dissolutionand fragmentation of chrysotile fibers that was consistent for pure chrysotile control and BD samples.Conclusions:The long, free, respirable chrysotile fibers were present in BD, yet were of low bio-dur-ability; incubation in artificial lysosomal fluid led to destruction of free fibers

Lung Function in Korean Adolescent Girls: in Association with Obesity and the Menstrual Cycle

Gender differences in asthma have been observed with a preponderance of boys affected before puberty and girls during and after puberty. The known influences of the menstrual cycle on asthma support a role for female sex hormones on the changing expression of asthma during adolescence. The purpose of this study was to investigate obesity, the menstrual cycle and lung function in adolescent girls. One hundred and three female high school girls (mean age: 15.9±0.8 yr) were enrolled. The investigation was performed using a questionnaire that included history of asthma, the menstrual cycle, other combined allergic disease and obesity. The skin prick and pulmonary function test during menstruation period and non-menstruation period. Analyses of these factors were compared. The forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) was significantly lower in the obese group compared to the non-obese group (99.8±13.8 vs. 107.1±10.2, p=0.03). The FEV1 was significantly lower in the girls during menstruation period than in the girls who were not on menstruation (77.5±10.2 vs. 80.4±8.6, p=0.03). Our results showed that changes of pulmonary function were related to menstrual cycle and obesity in Korean adolescent girls

Mesothelioma and asbestosis in a young woman following occupational asbestos exposure: Short latency and long survival: Case Report

A 27-year-old female white-collar worker was diagnosed in 1998 with mesothelioma eight and one-half years following first exposure as a bystander to debris in a site in which asbestos-containing building materials were being dismantled and rebuilding work took place. Prodromal back pain had been present for a year and a half. She underwent extrapleural pneumectomy and received an intrapleural infusion of cisplatin post-operatively. Exposure to asbestos was verified by contemporary reports and lung biopsy, which demonstrated asbestos bodies and microscopic interstitial fibrosis -conforming evidence for asbestosis. The patient is alive and well 12 years after diagnosis and 14 years after onset of symptoms. The combination of an extremely short latency period and long survival following occupational exposure to asbestos dust is unique

Risk factors for respiratory work disability in a cohort of pulp mill workers exposed to irritant gases

<p>Abstract</p> <p>Background</p> <p>The association between chronic respiratory diseases and work disability has been demonstrated a number of times over the past 20 years, but still little is known about work disability in occupational cohorts of workers exposed to respiratory irritants. This study investigated job or task changes due to respiratory problems as an indicator of work disability in pulp mill workers occupationally exposed to irritants.</p> <p>Methods</p> <p>Data about respiratory symptoms and disease diagnoses, socio-demographic variables, occupational exposures, gassing episodes, and reported work changes due to respiratory problems were collected using a questionnaire answered by 3226 pulp mill workers. Information about work history and departments was obtained from personnel files. Incidence and hazard ratios for respiratory work disability were calculated with 95% confidence intervals (CI).</p> <p>Results</p> <p>The incidence of respiratory work disability among these pulp mill workers was 1.6/1000 person-years. The hazard ratios for respiratory work disability were increased for workers reporting gassings (HR 5.3, 95% CI 2.7-10.5) and for those reporting physician-diagnosed asthma, chronic bronchitis, and chronic rhinitis, when analyzed in the same model.</p> <p>Conclusions</p> <p>This cohort study of pulp mill workers found that irritant peak exposure during gassing episodes was a strong predictor of changing work due to respiratory problems, even after adjustment for asthma, chronic bronchitis, and chronic rhinitis.</p

Pulmonary function testing in quadriplegic subjects

Study design: Cross-sectional study.Objective: Pulmonary functional capacity in 23 Brazilian quadriplegic subjects (ASIA A), aged 30 (9.5) years, weight 66 (10.75) kg, height 176 (7) cm, was investigated at 42 ( 64) months postinjury.Setting: University Hospital-UNICAMP, Campinas, Brazil.Method: Subjects performed forced vital capacity ( FVC) and maximal voluntary ventilation (MVV) tests while seated in their standard wheelchairs. Forced Expired Volume after 1 s (FEV1) and FVC/FEV1 ratio were calculated from these tests. Values obtained were compared to three prediction equations from the literature that are used specifically for spinal cord subjects and include different variables in their formulae, such as age, gender, height, postinjury time and injury level. Data are expressed as median (interquartile interval). Differences between values were demonstrated by median confidence interval with significance level set at a 0.05.Results: Obtained data were statistically different from prediction equation results, with FVC 3.11 ( 0.81), 4.46 (0.28), 4.16 (0.33), 4.26 (0.42); FEV1 2.77 (1.03), 3.67 (0.21), 3.66 (0.30), 3.45 (0.39) and MVV 92 (27), 154.2 (11.9), 156.6 (14),157.3 (16.8), where the first value is obtained experimentally and the second, third and fourth values correspond to predicted values. the results obtained from spirometry test in this study differed significantly from the results obtained when prediction equations were used.Conclusion: the use of prediction equations developed to estimate pulmonary function in wheelchair users significantly overestimates pulmonary function of quadriplegic individuals with complete lesions (ASIA group A), in comparison to measured values.Univ Estadual Campinas, Dept Orthopedia & Traumatol, FCM, BR-13083970 Campinas, SP, BrazilUniv Estadual Campinas, Fac Phys Educ, BR-13083970 Campinas, SP, BrazilUniversidade Federal de São Paulo, Santos, SP, BrazilUniv São Paulo, Fac Med, Dept Biomech Med & Rehabil Locomotor Syst, BR-14049 Ribeirao Preto, BrazilUniv São Paulo, Dept Elect Engn, Sao Carlos, SP, BrazilUniversidade Federal de São Paulo, Santos, SP, BrazilWeb of Scienc

Modelling prevalence and incidence of fibrosis and pleural plaques in asbestos-exposed populations for screening and follow-up: a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>CT-Scan is currently under assessment for the screening of asbestos-related diseases. However, to date no consensus exists as to how to select high-risk asbestos-exposed populations suitable for such screening programs. The objective of this study is to select the most relevant exposure variables for the prediction of pleural plaques and asbestosis in order to guide clinicians in their use of CT-Scan.</p> <p>Methods</p> <p>A screening program of non malignant asbestos-related diseases by CT-scan was conducted among asbestos-exposed volunteers in France. Precise assessments of asbestos exposure were obtained by occupational hygiene measurements and a job-exposure matrix. Several parameters were calculated (time since first exposure, duration, intensity and cumulative exposure to asbestos). Predictive parameters of prevalence and incidence were then estimated by standard logistic and a complementary log-log regression models.</p> <p>Results</p> <p>1011 subjects were recruited in this screening program among them 474 (46.9%) presented with pleural plaques and 61 (6.0%) with interstitial changes compatible with asbestosis on CT-scan. Time since first exposure (p < 0.0001) and either cumulative or mean exposure (p < 0.0001) showed independent associations with both pleural plaques and asbestosis prevalence and pleural plaques incidence. Modelling incidence of pleural plaques showed a 0.8% to 2.4% yearly increase for a mean exposure of 1 f/ml.</p> <p>Conclusion</p> <p>Our findings confirmed the role played by time since first exposure and dose but not duration in asbestos-related diseases. We recommend to include these parameters in high-risk populations suitable for screening of these diseases. Short-periodicity of survey of pleural plaques by CT-Scan seemed not to be warranted.</p

Circulating alpha1-antitrypsin in the general population: Determinants and association with lung function

BACKGROUND: Severe alpha1-antitrypsin (AAT) deficiency associated with low AAT blood concentrations is an established genetic COPD risk factor. Less is known about the respiratory health impact of variation in AAT serum concentrations in the general population. We cross-sectionally investigated correlates of circulating AAT concentrations and its association with FEV1. METHODS: In 5187 adults (2669 females) with high-sensitive c-reactive protein (CRP) levels < or = 10 mg/l from the population-based Swiss SAPALDIA cohort, blood was collected at the time of follow-up examination for measuring serum AAT and CRP. RESULTS: Female gender, hormone intake, systolic blood pressure, age in men and in postmenopausal women, as well as active and passive smoking were positively, whereas alcohol intake and BMI inversely correlated with serum AAT levels, independent of CRP adjustment. We observed an inverse association of AAT with FEV1 in the total study population (p < 0.001), that disappeared after adjustment for CRP (p = 0.28). In addition, the AAT and FEV1 association was modified by gender, menopausal status in women, and smoking. CONCLUSION: The results of this population-based study reflect a complex interrelationship between tobacco exposure, gender related factors, circulating AAT, systemic inflammatory status and lung function
