La Perspectiva biofísica de la relació home-natura: economia ecològica

L'estudi de la relació entre l'activitat econòmica i el medi que ens envolta és antiga en economia. No obstant és cert que darrerament la teoria econòmica sembla haver-la oblidada. És per això que quan sortí la disciplina que avui s’anomena "economia ecològica" va implicar una ruptura amb la manera amb la qual la teoria econòmica convencional descrivia nostra relació amb el medi ambient. El present capítol pretén descriure breument el que creiem són les característiques principals que la fan diferent de la resta de disciplines: la inconmensurabilitat de valors, la seva anàlisi en termes biofísics, i les seves repercussions al nivell de la generació de polítiques, que la fan ser un exemple del que es coneix com a ciència post-normal.

Congenital and nursing effects on the evolution of Schistosoma mansoni infection in mice

Modification of the immune response to schistosomal infection in children or offspring born to mother R infected with Schistosoma mansoni has been demonstrated in human and in experimental schistosomiasis. One of the hypothesis to explain this fact could be the transfer of circulating antigens and antibodies from mother to foetus through the placenta or from mother to child by milk. The results of this spontaneous transference are controversial in the literature. In an attempt to investigate these questions, we studied one hundred and twenty offspring (Swiss mice), sixty born to infected-mothers (group A) and sixty born to non-infected mothers (group B). These were percutaneously infected with 50 cercariae/mouse, and divided in six sub-groups (20 mice/sub-group), according to the following schedule: after birth (sub-groups A.I and B.I), 10 days old (sub-groups A.II and B.II) and 21 days old (sub-groups A.III and B.III). After the exposure period, the young mice returned to their own mothers for nursing. Six weeks later, the mice were killed. We obtained the following results: 1) There is transference of antibody to cercariae (CAP), adult worms (SWAP) and egg antigens (SEA) from the infected mothers to the offspring, probably through placenta and milk; 2) Offspring born to infected mothers exhibit much less coagulative hepatic necrosis and show a lower number of eggs in the small intestine and a less intense and predominant exsudative stage of the hepatic granulomas when compared with the exsudative-productive stage of the control groups. The findings suggest that congenital and nursing factors can interfere on the development of the schistosomiasis infection, causing an hyporesponse to the eggs.

Structure du temps de travail des infirmières de santé publique: effets de l'âge des patients, de la nature des prestations fournies et du lieu du contact. [Structure of work times of public health nurses: effect of the age of patients, nature of care given and location of contact].

In the framework of health services research sponsored by the Swiss National Science Foundation, a research was undertaken of the activity of the large majority of the public health nurses working in the Swiss cantons of Vaud and Fribourg (total population 700,000). During one week, 130 nurses gathered, with a specially devised instrument, data on 4165 patient visits. Studying the duration of the contacts, one has distinguished contact duration per se (DC), duration of the travel time preceding the contact (DD), and total duration in relation with the contact (DTC-addition of the first two). It was noted that the three durations increased significantly with patient age (as regard travel time, this is explained by the higher proportion of home visits in higher age groups, as compared with visits at a health center). Examined according to location of the visit, contact duration per se (without travel) is higher for visits at home and in nursing homes than for those taking place at a health center. Looked at in respect to the care given (technical care, or basic nursing care, or both simultaneously), our data show that the provision of basic nursing care (alone or with technical care) doubles contact duration (from 20 to 42-45'). The analyses according to patient age shows that, at an advanced age (beyond 80 years particularly), there is an important increase of the visits where both types of care are given. However, contact duration per se shows a significant raise with age only for the group "technical care only"; it can be demonstrated that this is due to the fact that older patients require more complex technical acts (e.g., bladder care, as compared with simpler acts such as injection). A model of the relationships between patient age and contact duration is proposed: it is because of the increase in the proportions of home visits, of visits including basic nursing care, and of more complex technical acts that older persons require more of the working time of public health nurses.

Le Q-sort, un outil pour la recherche en soins le cas des représentations chez les infirmiers en psychiatrie de l'âge avancé [Q-sort, a useful research method in care in cases of psychiatric nursing of the aged]

Q-sort is a research method which allows defining profiles of attitudes toward a set of statements, ordered in relation to each other. Pertaining to the Q Methodology, the qualitative analysis of the Q-sorts is based on quantitative techniques. This method is of particular interest for research in health professions, a field in which attitudes of patients and professionals are very important. The method is presented in this article, along with an example of application in nursing in old age psychiatry.

Plasma cell precursors: long-distance travelers looking for a home.

Little is known about the migration of plasma cell precursors to the lymph node medulla. In this issue of Immunity, Fooksman et al. (2010) propose that this migration is largely independent of chemotactic cues but follows a long linear walk of random orientation.

Measuring the diffusion of palliative care in long-term care facilities - a death census

ABSTRACT: BACKGROUND: The dissemination of palliative care for patients presenting complex chronic diseases at various stages has become an important matter of public health. A death census in Swiss long-term care facilities (LTC) was set up with the aim of monitoring the frequency of selected indicators of palliative care. METHODS: The survey covered 150 LTC facilities (105 nursing homes and 45 home health services), each of which was asked to complete a questionnaire for every non-accidental death over a period of six months. The frequency of 4 selected indicators of palliative care (resort to a specialized palliative care service, the administration of opiates, use of any pain measurement scale or other symptom measurement scale) was monitored in respect of the stages of care and analysed based on gender, age, medical condition and place of residence. RESULTS: Overall, 1200 deaths were reported, 29.1% of which were related to cancer. The frequencies of each indicator varied according to the type of LTC, mostly regarding the administration of opiate. It appeared that the access to palliative care remained associated with cancer, terminal care and partly with age, whereas gender and the presence of mental disorders had no effect on the indicators. In addition, the use of drugs was much more frequent than the other indicators. CONCLUSION: The profile of patients with access to palliative care must become more diversified. Among other recommendations, equal access to opiates in nursing homes and in home health services, palliative care at an earlier stage and the systematic use of symptom management scales when resorting to opiates have to become of prime concern.

Women at home, at school and in the factory. The particular discourse of domesticity done by the Spanish Escuela Economista (1861-1909)

The texts by the Spanish Economist School (second half of the 19th century) contain an assessment of the role of women in the economy and society that is transgressor in front of the prevailing discourse that defended a unique and exclusive role for all women: being at home and a mother. Most members of that economic trend defended female work in the factories, basing themselves on wage arguments and even asked for a professional training for those who in many cases could not even write and read for the fact of being a woman. The texts of those economists give new ideas about the economic and social role of women in a Spain dominated by a discourse that denied the necessity of female work for the working families.

Home i natura a la Vall de Riells

Considerant l’absència d’estudis ambientals previs a la Vall de Riells (Bigues i Riells, Vallès Oriental), i l’evident necessitat de gestió de l’espai a causa de la sobrefreqüentació antròpica, s’ha realitzat aquesta diagnosi ambiental. En ella es descriuen de manera integrada els principals elements del medi físic, biòtic i socioeconòmic, per tal de proporcionar les eines necessàries per avaluar les problemàtiques de l’espai i fomentar la seva gestió i conservació.

L'home que venia de Natzaret. El que avui podem saber de Jesus

Quina mena d'home era Jesús? Menut o espigat? Tenia el parlar sec, el gest franc? Era calb, duia barba?... Esperava que el reialme arribaria de seguida? Va patir, algun dia, el sentiment de fracàs? Imaginà que arribaria l'Església?L'autor manlleva els elements cabdals de les investigacions històriques més recents sobre Jesús i en fa un retrat molt particular: no és un retrat inèdit, sinó un retrat en què el rostre de Jesús es destria de moltes imatges amb què sovint se l'ha confós. Escoltant les seves paràboles, assistint als seus miracles, seguint-lo en el seu camí de la creu, el lector és conduït a descobrir que en ell Déu s'ha fet proper als homes i els ha donat un centre nou a la seva història.

L'Home d'Orce: una controvèrsia pública

L’any 1983, el fragment de crani VM-0, trobat a Venta Micena (Orce, Granada), va ser atribuït al gènere Homo per Josep Gibert, Salvador Moyà-Solà i Jordi Agustí. Un any més tard, el mateix fragment va ser atribuït a Equus per altres investigadors mitjançant el diari El País. No és fins a tres anys més tard que es publica el primer article científic seguint aquesta atribució. Només Josep Gibert continua defensant el caràcter humà de VM-0, que mai serà totalment acceptat per la comunitat científica. Els mitjans de comunicació, concretament els diaris, esdevenen l’espai de debat científic. Aquest debat, i el gran rebombori que causen els diaris, tenen influència en el desenvolupament "normal" de la ciència.
