Soft Surveillance: The Growth of Mandatory Volunteerism in Collecting Personal Information “Hey Buddy Can You Spare a DNA?”

Le développement accéléré des technologies de communication, de saisie et de traitement de l’information durant les dernières années décennies ouvre la voie à de nouveaux moyens de contrôle social. Selon l’auteur Gary Marx ceux-ci sont de nature non coercitive et permettent à des acteurs privés ou publics d’obtenir des informations personnelles sur des individus sans que ceux-ci y consentent ou mêmes sans qu’ils en soient conscients. Ces moyens de contrôle social se fondent sur certaines valeurs sociales qui sont susceptibles de modifier le comportement des individus comme le patriotisme, la notion de bon citoyen ou le volontarisme. Tout comme les moyens coercitifs, elles amènent les individus à adopter certains comportements et à divulguer des informations précises. Toutefois, ces moyens se fondent soit sur le consentement des individus, consentement qui est souvent factice et imposée, soit l’absence de connaissance du processus de contrôle par les individus. Ainsi, l’auteur illustre comment des organisations privées et publiques obtiennent des informations privilégiées sur la population sans que celle-ci en soit réellement consciente. Les partisans de tels moyens soulignent leur importance pour la sécurité et le bien publique. Le discours qui justifie leur utilisation soutient qu’ils constituent des limites nécessaires et acceptables aux droits individuels. L’emploi de telles méthodes est justifié par le concept de l’intérêt public tout en minimisant leur impact sur les droits des individus. Ainsi, ces méthodes sont plus facilement acceptées et moins susceptibles d’être contestées. Toutefois, l’auteur souligne l’importance de reconnaître qu’une méthode de contrôle empiète toujours sur les droits des individus. Ces moyens de contrôle sont progressivement intégrés à la culture et aux modes de comportement. En conséquence, ils sont plus facilement justifiables et certains groupes en font même la promotion. Cette réalité rend encore plus difficile leur encadrement afin de protéger les droits individuels. L’auteur conclut en soulignant l’important décalage moral derrière l’emploi de ces méthodes non-coercitives de contrôle social et soutient que seul le consentement éclairé des individus peut justifier leur utilisation. À ce sujet, il fait certaines propositions afin d’encadrer et de rendre plus transparente l’utilisation de ces moyens de contrôle social.

Saturated salt solutions for humidity control and the survival of dry powder and oil formulations of Beauveria bassiana conidia

Oil-based formulated conidia sprayed on steel plates and conidia powder (control) of Beauveria bassiana isolate IMI 386243 were stored at temperatures from 10 to 40 degrees C in desiccators over saturated salt solutions providing relative humidities from 32 to 88%, or in hermetic storage at 40 degrees C, and moisture contents in equilibrium with 33 or 77% relative humidity. The negative semi-logarithmic relation (P < 0.005) between conidia longevity (at 40 degrees C) and equilibrium relative humidity did not differ (P > 0.25) between formulated conidia and conidia powder. Despite this, certain saturated salts provided consistently greater longevity (NaCl) and others consistently shorter longevity (KCl) for formulated conidia compared to conidia powder. These results, analysis of previous data, and comparison with hermetic storage, indicate that storage of conidia over saturated salt solutions provides inconsistent responses to environment and so may be problematic for bio-pesticide research. In hermetic storage, oil formulation was not deleterious to longevity and in the more moist environment enhanced survival periods. (c) 2005 Elsevier Inc. All rights reserved.

DNA barcodes for Mexican Cactaceae, plants under pressure from wild collecting

DNA barcodes could be a useful tool for plant conservation. Of particular importance is the ability to identify unknown plant material, such as from customs seizures of illegally collected specimens. Mexican cacti are an example of a threatened group, under pressure because of wild collection for the xeriscaping trade and private collectors. Mexican cacti also provide a taxonomically and geographically coherent group with which to test DNA barcodes. Here, we sample the matK barcode for 528 species of Cactaceae including approximately 75% of Mexican species and test the utility of the matK region for species-level identification. We find that the matK DNA barcode can be used to identify uniquely 77% of species sampled, and 79-87% of species of particular conservation importance. However, this is far below the desired rate of 95% and there are significant issues for PCR amplification because of the variability of primer sites. Additionally, we test the nuclear ITS regions for the cactus subfamily Opuntioideae and for the genus Ariocarpus (subfamily Cactoideae). We observed higher rates of variation for ITS (86% unique for Opuntioideae sampled) but a much lower PCR success, encountering significant intra-individual polymorphism in Ariocarpus precluding the use of this marker in this taxon. We conclude that the matK region should provide useful information as a DNA barcode for Cactaceae if the problems with primers can be addressed, but matK alone is not sufficiently variable to achieve species-level identification. Additional complementary regions should be investigated as ITS is shown to be unsuitable

Collecting disability data from parents

This article describes the development and national trial of a methodology for collecting disability data directly from parents, enabling schools and local authorities to meet their obligations under the Disability Discrimination Act (DDA; 2005) to promote equality of opportunity for all children. It illustrates the complexities around collecting this information and also highlights the dangers of assuming that special educational needs (SENs) equate to disability. The parental survey revealed children with medical and mental health needs, but no SENs, who were unknown to schools. It also revealed children with a recorded SEN whose parents did not consider that they had a disability in line with the DDA definition. It identified a number of children whose disability leads to absences from school, making them vulnerable to underachievement. These findings highlight the importance of having appropriate tools with which to collect these data and developing procedures to support their effective use. We also draw attention to the contextual nature of children’s difficulties and the importance of retaining and respecting the place of subjective information. This is central to adopting a definition of disability that hinges on experience or impact.

Aquaporin 2 expression increased by glucagon in normal rat inner medullary collecting ducts

Yano Y, Cesar KR, Araujo M, Rodrigues Jr. AC, Andrade LC, Magaldi AJ. Aquaporin 2 expression increased by glucagon in normal rat inner medullary collecting ducts. Am J Physiol Renal Physiol 296: F54-F59, 2009. First published October 1, 2008; doi: 10.1152/ajprenal.90367.2008.-It is well known that Glucagon (Gl) is released after a high protein diet and participates in water excretion by the kidney, principally after a protein meal. To study this effect in in vitro perfused inner medullary collecting ducts (IMCD), the osmotic water permeability (Pf; mu m/s) at 37 degrees C and pH 7.4 in normal rat IMCDs (n = 36) perfused with Ringer/HCO(3) was determined. Gl (10(-7) M) in absence of Vasopressin (AVP) enhanced the Pf from 4.38 +/- 1.40 to 11.16 +/- 1.44 mu m/s (P < 0.01). Adding 10(-8), 10(-7), and 10(-6) M Gl, the Pf responded in a dose-dependent manner. The protein kinase A inhibitor H8 blocked the Gl effect. The specific Gl inhibitor, des-His(1)-[Glu(9)] glucagon (10(-7) M), blocked the Gl-stimulated Pf but not the AVP-stimulated Pf. There occurred a partial additional effect between Gl and AVP. The cAMP level was enhanced from the control 1.24 +/- 0.39 to 59.70 +/- 15.18 fm/mg prot after Gl 10(-7) M in an IMCD cell suspension. The immunoblotting studies indicated an increase in AQP2 protein abundance of 27% (cont 100.0 +/- 3.9 vs. Gl 127.53; P = 0.0035) in membrane fractions extracted from IMCD tubule suspension, incubated with 10(-6) M Gl. Our data showed that 1) Gl increased water absorption in a dose-dependent manner; 2) the anti-Gl blocked the action of Gl but not the action of AVP; 3) Gl stimulated the cAMP generation; 4) Gl increased the AQP2 water channel protein expression, leading us to conclude that Gl controls water absorption by utilizing a Gl receptor, rather than a AVP receptor, increasing the AQP2 protein expression.

Comparison of two methods for collecting free-living ticks in the Amazonian forest

In the present study, we compared 2 methods for collecting ixodid ticks on the verges of animal trails in a primary Amazon forest area in northern Brazil. (i) Dragging: This method was based on passing a 1-m(2) white flannel over the vegetation and checking the flannel for the presence of caught ticks every 5-10 m. (ii) Visual search: This method consisted of looking for guesting ticks on the tips of leaves of the vegetation bordering animal trails in the forest. A total of 103 adult ticks belonging to 4 Amblyomma species were collected by the visual search method on 5 collecting dates, while only 44 adult ticks belonging to 3 Amblyomma species were collected by dragging on 5 other collecting dates. These values were statistically different (Mann-Whitney Test, P = 0.0472). On the other hand, dragging was more efficient for subadult ticks, since no larva or nymph was collected by visual search, whereas 18 nymphs and 7 larvae were collected by dragging. The visual search method proved to be suitable for collecting adult ticks in the Amazon forest: however, field studies should include a second method, such as dragging in order to maximize the collection of subadult ticks. Indeed, these 2 methods can be performed by a single investigator at the same time, while he/she walks on an animal trail in the forest. (C) 2010 Elsevier GmbH. All rights reserved.

Proteins and Peptidases from Conidia and Mycelia of Scedosporium apiospermum Strain HLPB

The conidia-mycelia transformation is an essential step during the life cycle of the fungal human pathogens of the Pseudallescheria boydii complex. In the present study, we have analyzed the protein and peptidase profiles in two distinct morphological stages, conidia and mycelia, of Scedosporium apiospermum sensu stricto. Proteins synthesized by the mycelia, migrating at the ranges of 62-48 and 22-18 kDa, were not detected from the conidial extract. Conidia produced a single cellular peptidase of 28 kDa able to digest copolymerized albumin, while mycelia yielded 6 distinct peptidases ranging from 90 to 28 kDa. All proteolytic enzymes were active at acidic pH and fully inhibited by 1,10-phenanthroline, characterizing these activities as metallo-type peptidases. Quantitative peptidase assay, using soluble albumin, showed a high metallopeptidase production in mycelial cells in comparison with conidia. The regulated expression of proteins and peptidases in different morphological stages of S. apiospermum represents a potential target for isolation of stage-specific markers for biochemical and immunological analysis.
