Worlds of working poverty : Cross-national variation in the mechanisms that lead to poverty among workers

The objective of this paper is to distinguish between different types of working poverty, on the basis of the mechanisms that produce it. Whereas the poverty literature identifies a myriad of risk factors and of categories of disadvantaged workers, we focus on three immediate causes of working poverty, namely low wage rate, weak labour force attachment, and high needs, the latter mainly due to the presence of children (and sometimes to the increase in needs caused by a divorce). These three mechanisms are the channels through which macroeconomic, demographic and policy factors have a direct bearing on working households. The main assumption tested here is that welfare regimes strongly influence the relative weight of these three mechanisms in producing working poverty, and, hence, the composition of the working-poor population. Our figures confirm this hypothesis and show that low-wage employment is a key factor, but, by far, not the only one and that family policies broadly understood play a decisive role, as well as patterns of labour market participation and integration.

Gender inequalities in occupational health related to the unequal distribution of working and employment conditions: a systematic review

Gender inequalities exist in work life, but little is known about their presence in relation to factors examined in occupation health settings. The aim of this study was to identify and summarize the working and employment conditions described as determinants of gender inequalities in occupational health in studies related to occupational health published between 1999 and 2010. A systematic literature review was undertaken of studies available in MEDLINE, EMBASE, Sociological Abstracts, LILACS, EconLit and CINAHL between 1999 and 2010. Epidemiologic studies were selected by applying a set of inclusion criteria to the title, abstract, and complete text. The quality of the studies was also assessed. Selected studies were qualitatively analysed, resulting in a compilation of all differences between women and men in the prevalence of exposure to working and employment conditions and work-related health problems as outcomes. Most of the 30 studies included were conducted in Europe (n=19) and had a cross-sectional design (n=24). The most common topic analysed was related to the exposure to work-related psychosocial hazards (n=8). Employed women had more job insecurity, lower control, worse contractual working conditions and poorer self-perceived physical and mental health than men did. Conversely, employed men had a higher degree of physically demanding work, lower support, higher levels of effort-reward imbalance, higher job status, were more exposed to noise and worked longer hours than women did. This systematic review has identified a set of working and employment conditions as determinants of gender inequalities in occupational health from the occupational health literature. These results may be useful to policy makers seeking to reduce gender inequalities in occupational health, and to researchers wishing to analyse these determinants in greater depth.

International Society of Urological Pathology (ISUP) Consensus Conference on Handling and Staging of Radical Prostatectomy Specimens. Working group 4: seminal vesicles and lymph nodes.

The 2009 International Society of Urological Pathology Consensus Conference in Boston made recommendations regarding the standardization of pathology reporting of radical prostatectomy specimens. Issues relating to the infiltration of tumor into the seminal vesicles and regional lymph nodes were coordinated by working group 4. There was a consensus that complete blocking of the seminal vesicles was not necessary, although sampling of the junction of the seminal vesicles and prostate was mandatory. There was consensus that sampling of the vas deferens margins was not obligatory. There was also consensus that muscular wall invasion of the extraprostatic seminal vesicle only should be regarded as seminal vesicle invasion. Categorization into types of seminal vesicle spread was agreed by consensus to be not necessary. For examination of lymph nodes, there was consensus that special techniques such as frozen sectioning were of use only in high-risk cases. There was no consensus on the optimal sampling method for pelvic lymph node dissection specimens, although there was consensus that all lymph nodes should be completely blocked as a minimum. There was also a consensus that a count of the number of lymph nodes harvested should be attempted. In view of recent evidence, there was consensus that the diameter of the largest lymph node metastasis should be measured. These consensus decisions will hopefully clarify the difficult areas of pathological assessment in radical prostatectomy evaluation and improve the concordance of research series to allow more accurate assessment of patient prognosis.

Anàlisi d'un treball de força explosiva combinant màquines vibratòries i màquines inercials

L’objectiu d’aquest estudi és comparar els efectes de dos mitjans de treball sobre la força explosiva en 9 atletes de nivell autonòmic i nacional (19,6 ± 2,6 anys, 1,76 ± 7 m i 68,9 ± 3,5 kg) que entrenaren durant el període competitiu, 6 setmanes amb una freqüència de 2 cops per setmana, seguint una periodització creixent. Els subjectes varen ser dividits en 3 grups de 3 atletes cada un, però utilitzant diferents mitjans d’entrenament: el grup experimental combinant la plataforma vibratòria i les màquines inercials (1), amb un temps d’exposició a la vibració de 30’’, a una intensitat de 45 Hz i una amplitud de 5 mm amb una pausa d’1’. I de 3 sèries de 8 repeticions executades a màxima velocitat en la fase concèntrica i controlant aquesta en la fase excèntrica, amb una pausa de 3’ en les màquines io-io. El grup experimental de pesos lliures (2), va realitzar 4 exercicis: ½ squat, pliometria (CEE), multisalts horitzontals i acceleracions, seguint les pautes d’un treball de força explosiva proposat per Badillo i Gorostiaga (1995). I un grup control (3), que no realitzà cap entrenament de força. Abans i després del període d’intervenció és realitzaren els següents tests: salt sense contramoviment (SJ) i salt amb contramoviment (CMJ). Els resultats indicaren que el grup (1), (2) i (3) disminuïren significativament el SJ i el CMJ. Es conclou que l’entrenament, tant en el de combinació d’estímuls vibratoris amb màquines inercials com el de pesos lliures pareix ser un mitja que s’ha de controlar i perioditzar molt bé ja que en el període competitiu l’atleta acumula uns nivells de fatiga tant muscular com fisiològics molt superiors que en altres períodes de la temporada.

Who knew? Awareness of being recommended for influenza vaccination among US adults

Please cite this paper as: Maurer et al. (2012) Who knew? Awareness of being recommended for influenza vaccination among US adults. Influenza and Other Respiratory Viruses 6(4), 284-290. Background  Starting with the 2010-2011 influenza season, the Advisory Committee on Immunization Practices at the US Centers for Disease Control and Prevention recommends annual influenza vaccination to all people aged 6 months and older unless contraindicated. Objectives  To measure perceived influenza vaccination recommendation status among US adults (n = 2122) and its association with socio-demographic characteristics and recommendation status during the 2009-2010 pandemic influenza season. Methods  We analyze nationally representative data from longitudinal Internet surveys of US adults conducted in November-December 2009 and September-October 2010. Results  During the 2010-2011 vaccination season, 46·2 percent (95%-CI: 43·3-49·1%) of US adults correctly reported to be covered by a government recommendation for influenza vaccination. Awareness of being covered by a government influenza vaccination recommendation was statistically significantly higher among non-working adults and adults who had been recommended for seasonal vaccination or both seasonal and H1N1 vaccination during the 2009-2010 pandemic influenza vaccination season. Conclusion  Our results highlight that a majority of US adults do not know that they are recommended for annual influenza vaccination by the government. The fraction of adults who are unaware of their recommendation status is especially large among newly recommended healthy young adults. The universal vaccination recommendations will only be successful if they reach both patients and physicians and lead to changing vaccination practices. The universal nature of the new recommendation simplifies vaccination-related outreach and compliance with government vaccination guidelines considerably, as it does not require any identification of specific recommendation groups based on complex personal or health risk factors.

Effect of Bacillus thuringiensis on microbial functional groups in sorghum rhizosphere

The objective of this work was to assess the effect of two strains of Bacillus thuringiensis var. kurstaki on sorghum rhizosphere microorganisms. The strains were HD1, that produces the bioinsecticidal protein, and 407, that is a mutant non-producer. The strains do not influence microbial population, but reduce plant growth and improve mycorrhizal colonization and free living fixing N2 community.

Carbon and oxygen isotope working standards from C-3 and C-4 photosynthates

A preparation of organic working standards for the online measurement of C-13/C-12 and O-18/O-16 ratios in biological material is presented. The organic working standards are simple and inexpensive C-3 and C-4 carbohydrates ( sugars or cellulose) from distinct geographic origin, including white sugar, toilet and XEROX papers from Switzerland, maize from Ivory Coast, cane sugar from Brazil, papyrus from Egypt, and the core of the stem of a Cyperus papyrus plant from Kenya. These photosynthetic products were compared with International Atomic Energy standards CH-3 and CH-6 and other calibration materials. The presented working standards cover a 15 parts per thousand range of C-13/C-12 ratios and 9 parts per thousand for O-18/O-16, with a precision < +/- 0.2 parts per thousand for n > 10.

Using STD occurence to monitor AIDS prevention : final report of the Working Group on STD Surveillance.

The overall aim of the project has been to assess the extent to which data on the frequency of occurence of STDs [Sexually transmitted diseases] might be useful in the monitoring and evaluation of AIDS prevention programmes. The objectives have been to answer the following questions: (a) Can measures of STD occurence be used as an outcome measure of AIDS/HIV preventive efforts ? In particular: -> which diseases might be useful ? -> in what ways could they be used ? (b) If measures of STD occurence can be used in this way, is existing surveillance data in Western Europe adequate for the purpose ? If not why not ? (c) What do data from existing STD surveillance systems tell us about the success or failure of AIDS prevention to date ? (d) What needs to be done in order taht STD surveillance data in the countries of Western Europe could be used for this purpose ? [Authors, p. 4]

Working memory in schizophrenia: dynamic visuo-spatial information processing

Working memory, commonly defined as the ability to hold mental representations on line transiently and to manipulate these representations, is known to be a core deficit in schizophrenia. The aim of the present study was to investigate the visuo-spatial component of the working memory in schizophrenia, and more precisely to what extent the dynamic visuo-spatial information processing is impaired in schizophrenia patients. For this purpose we used a computerized paradigm in which 29 patients with schizophrenia (DSMIV, Diagnostic Interview for Genetic Studies) and 29 age and sex matched control subjects (DIGS) had to memorize a plane moving across the computer screen and to identify the observed trajectory among 9 plots proposed together. Each trajectory could be seen max. 3 times if needed. The results showed no difference between schizophrenia patients and controls regarding the number of correct trajectory identified after the first presentation. However, when we determine the mean number of correct trajectories on the basis of 3 trials, we observed that schizophrenia patients are significantly less performant than controls (Mann-Whitney, p _ 0.002). These findings suggest that, although schizophrenia patients are able to memorize some dynamic trajectories as well as controls, they do not profit from the repetition of the trajectory presentation. These findings are congruent with the hypothesis that schizophrenia could induce an unbalance between local and global information processing: the patients may be able to focus on details of the trajectory which could allow them to find the right target (bottom-up processes), but may show difficulty to refer to previous experience in order to filter incoming information (top-down processes) and enhance their visuo-spatial working memory abilities.
