Els Robatoris silenciosos a Sant Cugat del Vallès : conseqüència d'un determinat model urbanístic?

Robatoris a l’interior d’habitatges n’hi ha hagut sempre amb més o menys intensitat. Fins fa poc modus operandi tradicional consistia en assaltar aquells habitatges on hi pogués haver béns de cert valor econòmic, durant períodes d’estiu i aprofitant sempre l’absència dels seus propietaris. Va ser a mitjan de l’any 2006 quan l’anomenada primera i segona corona metropolitana van començar a patir una onada de robatoris on el tret comú denominador era que el qui assaltaven actuaven quan els propietaris dormien i actuaven amb una manca d’escrúpols a l’hora d’emprar la violència si aquests esdespertaven. Més tard aquests tipus de delicte es va estendre a tot el territori català, principalment a les comarques de Tarragona i de Girona. El que té de nou aquesta forma delictiva és que es realitza el robatori amb els habitants de la casa a dins, normalment dormint. Per tant ja no és un delicte únicament contra la propietat sinó també contra la llibertat de les persones i, si s’utilitza violència contra els propietaris dels habitatges, contra la seva integritat física. La forma de cometre aquests delictes va fer que es coneguessin com a robatoris silenciosos, terme que va passar de l’àmbit policial a l’àmbit periodístic, o potser va ser al revés.

Ecomobilitat a Sitges: anàlisi de la situació actual i propostes de millora

La mobilitat urbana és una de les temàtiques més importants a les ciutats ja que convergeixen diversos aspectes a nivell social i ambiental. El present article es centra en el sistema de mobilitat de la ciutat de Sitges tot avaluant l’estat de la xarxa viària, el parc de vehicles, els sistemes de transport i els serveis bàsics actuals. En l’anàlisi socioambiental de les variables d’aquest àmbit, s’han detectat una sèrie de problemes com ara una distribució no equitativa dels serveis bàsics, desigualtat en la distribució de carrers vianalitzats i carrils bici i manca d’homogeneïtat en la distribució de pàrquings. Els resultats obtinguts permeten proposar una sèrie de millores en busca d’una mobilitat més sostenible. Millorar les parades de bus que no tenen sistema de marquesina per a protegir-les del fred i el sol, augmentar potencialment el carril bici desplegant-lo per carrers que no en tenen, desenvolupar campanyes per a fomentar l’ús de la bici i augmentar la presència de carrers d’exclusiu ús per a vianants.

Les ciutats turístiques, les noves ciutats. Anàlisi de l'evolució del model turístic en destinacions de litoral madures a partir de l'anàlisi de paràmetres urbanístics

La beca concedida ha anat destinada a desenvolupar la tesi doctoral que duu per nom "Les ciutats turístiques, les noves ciutats. Anàlisi de l'evolució del model turístic en destinacions de litoral madures a partir de l'anàlisi de paràmetres urbanístics". L’àrea d’estudi comprèn els municipis de Cambrils, Salou i La Pineda (Vila-seca) que conformen la Costa Daurada central, destinació madura de litoral mediterrani, que basa el seu desenvolupament d’acord el model turístic de sol i platja. Arribats en aquest punt de finalització de la beca, cal destacar que s’ha complert amb l'objectiu d'analitzar el procés de transformació de les ciutats turístiques, tot establint com el turisme litoral mediterrani s'ha convertit en un factor de creació de ciutat. Així mateix també s'han complert els objectius específics tals com: analitzar l'evolució de les destinacions turístiques consolidades del litoral mediterrani, recopilar informació per a la creació d'índexs i eines que serveixin per l'anàlisi del procés de tranformació de les ciutats turístiques a ciutats tradicionals a partir del tractament dels plans parcials, recopilar i analitzar les polítiques de planificació que han condicionat l'area d'estudi, modelitzar el procés de construcció de l'espai turístic a partir de l'establiment d'unes unitats bàsiques en la descripció i anàlisi territorial i paisatgístic, i crear un SIG per culminar el procés d'anàlisi tot creant una base de dades i la representació dels resultats en cartogradia temàtica. Pel que fa al disseny i l’execució de la metodologia, es poden considerar dos vessants, una vessant més qualitativa i una altra més quantitativa per al tractament de la informació recopilada. Igualment la generació de cartografia específica completa el procés amb la producció de cartografia específica, tal i com es desenvolupa en la present memòria. La tesi parteix del guió que contempla: un prier capítol d'introducció, un segon dedicat al marc teòric, un tercer apartat on s'exposaran les hipòtesis de les quals es parteix, i un quart dedicat a la metodologia. Pren especial importància l'apartat dedicat a l’ànalisi, així com el dedicat a la discussió dels resultats obtinguts, que es desenvoluparà en el sisè apartat. Per últim resta destacar el setè apartat dedicat a les conclusions a les que s'ha arribat.

Suitability of containers from different sources as breeding sites of Aedes aegypti (L.) in a cemetery of Buenos Aires City, Argentina

Cemeteries are ideal urban areas to study the importance of different types of containers as breeding sites of Aedes aegypti (L.). In the present study, the suitability of plastic, glass, ceramic and metal containers was evaluated in four patches within a cemetery of Buenos Aires City, Argentina. Between October 1998 and May 2000, we found 215 breeding sites of Ae. aegypti out of 13,022 water-filled containers examined. In two patches containing microenvironments sheltered from the sun, the use of the different types of containers was proportional to the offer (correlation coefficient = 0.99, P < 0.05 in both cases). In the remaining patches, plastic and metal containers were the most and less frequent breeding sites, respectively (P < 0.001 in both cases). The number of immatures per breeding site (median = 4.5) did not show significant differences among the four types of containers examined (H3, 215 = 1.216, P = 0.749). Differences found in patches from a same cemetery suggest that different microenvironmental conditions affect the suitability of each type of container for Ae. aegypti breeding. Plastic containers appeared as key breeding sites that should be removed to reduce the Ae. aegypti population in the study area.

Towards standardization of UV eye protection: what can be learned from photodermatology?

While knowledge about standardization of skin protection against ultraviolet radiation (UVR) has progressed over the past few decades, there is no uniform and generally accepted standardized measurement for UV eye protection. The literature provides solid evidence that UV can induce considerable damage to structures of the eye. As well as damaging the eyelids and periorbital skin, chronic UV exposure may also affect the conjunctiva and lens. Clinically, this damage can manifest as skin cancer and premature skin ageing as well as the development of pterygia and premature cortical cataracts. Modern eye protection, used daily, offers the opportunity to prevent these adverse sequelae of lifelong UV exposure. A standardized, reliable and comprehensive label for consumers and professionals is currently lacking. In this review we (i) summarize the existing literature about UV radiation-induced damage to the eye and surrounding skin; (ii) review the recent technological advances in UV protection by means of lenses; (iii) review the definition of the Eye-Sun Protection Factor (E-SPF®), which describes the intrinsic UV protection properties of lenses and lens coating materials based on their capacity to absorb or reflect UV radiation; and (iv) propose a strategy for establishing the biological relevance of the E-SPF.

Demyelination in mild cognitive impairment suggests progression path to Alzheimer's disease.

The preclinical Alzheimer's disease (AD) - amnestic mild cognitive impairment (MCI) - is manifested by phenotypes classified into exclusively memory (single-domain) MCI (sMCI) and multiple-domain MCI (mMCI). We suggest that typical MCI-to-AD progression occurs through the sMCI-to-mMCI sequence as a result of the extension of initial pathological processes. To support this hypothesis, we assess myelin content with a Magnetization Transfer Ratio (MTR) in 21 sMCI and 21 mMCI patients and in 42 age-, sex-, and education-matched controls. A conjunction analysis revealed MTR reduction shared by sMCI and mMCI groups in the medial temporal lobe and posterior structures including white matter (WM: splenium, posterior corona radiata) and gray matter (GM: hippocampus; parahippocampal and lingual gyri). A disjunction analysis showed the spread of demyelination to prefrontal WM and insula GM in executive mMCI. Our findings suggest that demyelination starts in the structures affected by neurofibrillary pathology; its presence correlates with the clinical picture and indicates the method of MCI-to-AD progression. In vivo staging of preclinical AD can be developed in terms of WM/GM demyelination.

The advantage of letrozole over tamoxifen in the BIG 1-98 trial is consistent in younger postmenopausal women and in those with chemotherapy-induced menopause.

Letrozole, an aromatase inhibitor, is ineffective in the presence of ovarian estrogen production. Two subpopulations of apparently postmenopausal women might derive reduced benefit from letrozole due to residual or returning ovarian activity: younger women (who have the potential for residual subclinical ovarian estrogen production), and those with chemotherapy-induced menopause who may experience return of ovarian function. In these situations tamoxifen may be preferable to an aromatase inhibitor. Among 4,922 patients allocated to the monotherapy arms (5 years of letrozole or tamoxifen) in the BIG 1-98 trial we identified two relevant subpopulations: patients with potential residual ovarian function, defined as having natural menopause, treated without adjuvant or neoadjuvant chemotherapy and age ≤ 55 years (n = 641); and those with chemotherapy-induced menopause (n = 105). Neither of the subpopulations examined showed treatment effects differing from the trial population as a whole (interaction P values are 0.23 and 0.62, respectively). Indeed, both among the 641 patients aged ≤ 55 years with natural menopause and no chemotherapy (HR 0.77 [0.51, 1.16]) and among the 105 patients with chemotherapy-induced menopause (HR 0.51 [0.19, 1.39]), the disease-free survival (DFS) point estimate favoring letrozole was marginally more beneficial than in the trial as a whole (HR 0.84 [0.74, 0.95]). Contrary to our initial concern, DFS results for young postmenopausal patients who did not receive chemotherapy and patients with chemotherapy-induced menopause parallel the letrozole benefit seen in the BIG 1-98 population as a whole. These data support the use of letrozole even in such patients.

Evaluation of a malaria antibody enzyme immunoassay for use in blood screening

Transfusion-transmitted malaria is rare, but it may produce severe problem in the safety of blood transfusion due to the lack of reliable procedure to evaluate donors potentially exposed to malaria. Here, we evaluated a new enzyme-linked immunosorbent assay malaria antibody test (ELISA malaria antibody test, DiaMed, Switzerland) to detect antibodies to Plasmodium vivax (the indigenous malaria) in the blood samples in the Republic of Korea (ROK). Blood samples of four groups were obtained and analyzed; 100 samples from P.vivax infected patients, 35 from recovery patients, 366 from normal healthy individuals, and 325 from domestic travelers of non-endemic areas residents to risky areas of ROK. P.vivax antibody levels by ELISA were then compared to the results from microscopic examination and polymerase chain reaction (PCR) test. As a result, the ELISA malaria antibody test had a clinical sensitivity of 53.0% and a clinical specificity of 94.0% for P.vivax. Twenty out of 325 domestic travelers (6.2%) were reactive and 28 cases (8.6%) were doubtful. Of the reactive and doubtful cases, only two were confirmed as acute malaria by both microscopy and PCR test. Thus we found that the ELISA malaria antibody test was insufficiently sensitive for blood screening of P.vivax in ROK.

Predicting random level and seasonality of hotel prices. A structural equation growth curve approach

This article examines the effect on price of different characteristics of holiday hotels in the sun-and-beach segment, under the hedonic function perspective. Monthly prices of the majority of hotels in the Spanish continental Mediterranean coast are gathered from May to October 1999 from the tour operator catalogues. Hedonic functions are specified as random-effect models and parametrized as structural equation models with two latent variables, a random peak season price and a random width of seasonal fluctuations. Characteristics of the hotel and the region where they are located are used as predictors of both latent variables. Besides hotel category, region, distance to the beach, availability of parking place and room equipment have an effect on peak price and also on seasonality. 3- star hotels have the highest seasonality and hotels located in the southern regions the lowest, which could be explained by a warmer climate in autumn

Latitude gradients in melanoma incidence and mortality in the non-Maori population of New Zealand

The variation with latitude of incidence and mortality for cutaneous malignant melanoma (CMM) in the non-Maori population of New Zealand was assessed. For those aged 20 to 74 years, the effects of age, time period, birth-cohort, gender, and region (latitude), and some interactions between them were evaluated by log-linear regression methods. Increasing age-standardized incidence and mortality rates with increasing proximity to the equator were found for men and women. These latitude gradients were greater for males than females. The relative risk of melanoma in the most southern part of New Zealand (latitude 44 degrees S) compared with the most northern region (latitude 36 degrees S) was 0.63 (95 percent confidence interval [CI] = 0.60-0.67) for incidence and 0.76 (CI = 0.68-0.86) for mortality, both genders combined. The mean percentage change in CMM rates per degree of latitude for males was greater than those reported in other published studies. Differences between men and women in melanoma risk with latitude suggest that regional sun-behavior patterns or other risk factors may contribute to the latitude gradient observed.

Absonifibula estuarina sp. n. (Monogenea: Diclidophoridae) parasite of juvenile Cynoscion guatucupa (Osteichthyes) from southwestern Atlantic Ocean

Absonifibula estuarina sp. n. (Diclidophoridae, Absonifibulinae), is described from the gills of juvenile striped weakfish, Cynoscion guatucupa (Cuvier), from the southwestern Atlantic, Argentinean coast. This marine fish migrates to estuarine areas to spawn where exclusively juveniles are found parasitized; adult fish in marine water were never found to be parasitized by this monogenean. A. estuarina sp. n. is characterized mainly by the pedunculate clamps dissimilar in size, the shape of anterior jaw with sclerite 'a' attached to a sub-trapezoidal lamellate extension and fused to sclerites 'c' and 'd'. It differs from Absonifibula bychowskyi Lawler & Overstreet, 1976, the only known species of the genus, in the shape and arrangement of the genital corona, which is armed with six similar hooks disposed in circle and the sub-trapezoidal shape of lamellate extension ('b'). The restriction to juvenile sciaenids is a shared feature among the Absonifibulinae indicating an estuary-dependent life cycle.
