Occupational respiratory diseases in South Africa results from SORDSA, 1997- 1999

Objectives. To describe the nature and extent of work-related respiratory diseases reported to the national Surveillance of Work-related and Occupational Respiratory Diseases in South Africa (SORDSA) reporting scheme. The causative agents and industrial categories in which they occurred are also characterised.Design. Voluntary monthly reporting of newly diagnosed cases by pulmonologists, occupational medicine practitioners and occupational health nurses.Setting. Medical and occupational health referral centres in the nine provinces of South Africa.Subjects. Cases were workers from non-mining industries or ex-miners, suffering from a newly diagnosed occupational respiratory disease, reported to SORDSA between October 1996 and December 1999.Outcome measures. Frequencies of reported occupational respiratory disease by year, reporting source, province and sex. Frequencies of short- and long-latency diseases by industry and causative agent.Results. There was incomplete reporting coverage of the nine provinces in the first 3 years. Reporting was most comprehensive from Gauteng, KwaZulu-Natal and the Western Cape. Diseases with long latency periods made up 76.2% of the cases. Pneumoconiosis, even in non-mining industries, was the most frequently reported disease, followed by inhalation accidents. Occupational asthma was the fourth most reported disease. Apart from the prominence of pneumoconiosis, the results obtained by . SORDSA are similar to those from a British occupational lung disease surveillance scheme. This study showed that newly diagnosed cases of occupational lung disease occurred in many industries and were caused by a variety of agents.Conclusion. SORDSA has contributed insight into the nature, extent and distribution of occupational respiratory diseases in South Africa. It has also highlighted important causes of occupational respiratory diseases in South Africa, as well as hazardous industries. The data indicate that South Africa has a widespread occupational lung disease problem, and provide a platform for targeted prevention strategies

Move your money? Sustainability Transitions in Regimes and Practices in the UK Retail Banking Sector

We present and test a new conceptual framework for understanding sustainable transitions in co-evolutionary sociotechnical systems. We apply this in the first study of sustainable transitions in UK retail banking. This system has suffered recently from banking crises, and links to environmentally-sensitive industries such as fossil fuels. Sustainability-focused values-based banks are a potential solution, but have had little impact on mainstream banking systems. We aim to understand the constraints on a potential transition and how to overcome them. Our new approach identifies the intersections between transitions in regimes (using the multi-level perspective MLP) and transitions in practices (using social practice theory SPT), two competing conceptual frameworks in the literature. We ask: what are the intersections between transitions in the banking regime and banking practices, and how may critical points of constraint be unlocked to become points of opportunity, thereby aiding a transition to more sustainable banking systems? We present new empirical findings from a mixed-method case study of the UK banking sector and two values-based banks in particular. Interventions for growing sustainable banking are identified and we demonstrate the added-value of the combined approach through indicating strategies for unlocking the transformative potential of sustainable innovations

Anatomical study of the female reproductive system and bacteriome of Diaphorina citri Kuwayama, (Insecta: Hemiptera, Liviidae) using micro-computed tomography

Huanglongbing (HLB) (citrus greening disease) is one of the most serious bacterial diseases of citrus. It is caused by (1) Candidatus Liberibacter africanus, transmitted by Trioza erytreae and (2) C.L. asiaticus and C.L. americanus, transmitted by Diaphorina citri. As part of a multidisciplinary project on D. citri (www.citrusgreening.org), we made a detailed study, using micro-computed tomography, of the female abdominal terminalia, reproductive system (ovaries, accessory glands, spermatheca, colleterial (= cement) gland, connecting ducts, and ovipositor) and bacteriome, which we present here. New terms and structures are introduced and described, particularly concerning the spermatheca, ovipositor and bacteriome. The quality of images and bacteriome reconstructions are comparable, or clearer, than those previously published using a synchrotron or fuorescence in situ hybridisation (FISH). This study: reviews knowledge of the female reproductive system and bacteriome organ in D. citri; represents the frst detailed morphological study of D. citri to use micro-CT; and extensively revises existing morphological information relevant to psylloids, hemipterans and insects in general. High quality images and supplementary videos represent a signifcant advance in knowledge of psylloid anatomy and are useful tools for future research and as educational aids.Kansas State University (KSU) S15192.01University of Granada, USDA-NIFA S15192.01 2014-70016-2302

Emotional economic man:Calculation and anxiety management in investment decision making

Dominant theorisations of investment decision making remain firmly wedded to the notion of economic rationality, either as a postulate of how financial actors actually behave or as a normative ideal to which financial actors should strive. However, such frameworks have been developed largely without engaging financial market participants themselves. Based on 51 in-depth interviews with fund managers in various global financial centres, this article highlights a number of features of investment decision making that mainstream finance and behavioural approaches both fail adequately to describe. Drawing on psychoanalytic theory, it is shown how the inherent uncertainty of the investment process engenders a state of endemic anxiety among fund managers. This anxiety is managed via a range of mental defences, both conscious and unconscious. The importance fund managers place on meeting and putting trust in company management to ‘perform’ for them can equally be viewed as a means of alleviating anxiety rather than having any direct economic purpose. This article, furthermore, brings to light the crucial role that calculative techniques play in dealing with anxiety. Rather than constituting a means of restoring rationality or correcting cognitive biases, calculation can actually reinforce ego defences while simultaneously perpetuating the myth of homo economicus. Fund managers can be characterised as ‘doing’ but ‘not doing’ and ‘knowing’ but ‘choosing not to know’ and have to manage not only their clients' funds, but their own personal anxiety as well

Interactive three‐dimensional teaching models of the female and male pelvic floor

Controversies regarding structure and function of the pelvic floor persist because of its poor accessibility and complex anatomical architecture. Most data are based on dissection. This “surgical” approach requires profound prior knowledge, because applying the scalpel precludes a “second look.” The “sectional” approach does not entail these limitations, but requires segmentation of structures and three‐dimensional reconstruction. This approach has produced several “Visible Human Projects.” We dealt with limited spatial resolution and difficult‐to‐segment structures by proceeding from clear‐cut to more fuzzy boundaries and comparing segmentation between investigators. We observed that the bicipital levator ani muscle consisted of pubovisceral and puborectal portions; that the pubovisceral muscle formed, together with rectococcygeal and rectoperineal muscles, a rectal diaphragm; that the external anal sphincter consisted of its subcutaneous portion and the puborectal muscle only; that the striated urethral sphincter had three parts, of which the middle (urethral compressor) was best developed in females and the circular lower (“membranous”) best in males; that the rectourethral muscle, an anterior extension of the rectal longitudinal smooth muscle, developed a fibrous node in its center (perineal body); that the perineal body was much better developed in females than males, so that the rectourethral subdivision into posterior rectoperineal and anterior deep perineal muscles was more obvious in females; that the superficial transverse perineal muscle attached to the fibrous septa of the ischioanal fat; and that the uterosacral ligaments and mesorectal fascia colocalized. To facilitate comprehension of the modified topography we provide interactive 3D‐PDFs that are freely available for teaching purpose

Using micro‑computed tomography to reveal the anatomy of adult Diaphorina citri Kuwayama (Insecta: Hemiptera, Liviidae) and how it pierces and feeds within a citrus leaf

The Asian citrus psyllid (ACP), Diaphorina citri, is a harmful pest of citrus trees that transmits Candidatus Liberibacter spp. which causes Huanglongbing (HLB) (citrus greening disease); this is considered to be the most serious bacterial disease of citrus plants. Here we detail an anatomical study of the external and internal anatomy (excluding the reproductive system) using micro-computed tomography (micro-CT). This is the frst complete 3D micro-CT reconstruction of the anatomy of a psylloid insect and includes a 3D reconstruction of an adult feeding on a citrus leaf that can be used on mobile devices. Detailed rendered images and videos support frst descriptions of coxal and scapus antennal glands and sexual diferences in the internal anatomy (hindgut rectum, mesothoracic ganglion and brain). This represents a signifcant advance in our knowledge of ACP anatomy, and of psyllids in general. Together the images, videos and 3D model constitute a unique anatomical atlas and are useful tools for future research and as teaching aids.Kansas State University (KSU)University of Granad
