La generatividad en la vejez y su relación con el bienestar: ¿Quién más contribuye es quien más se beneficia?

El objetivo de la investigación fue la adaptación al español de las escalas de interés y comportamientos generativos de McAdams, así co-mo el estudio de la generatividad en la vejez y su relación con el bienestar. La muestra estuvo compuesta por 165 voluntarios mayores de 65 años que, además de las versiones españolas de las escalas de generatividad, completa-ron instrumentos para evaluar satisfacción con la vida y orientación al futu-ro. Los resultados indicaron que la fiabilidad de las versiones españolas de las escalas de generatividad fue aceptable y similar a las originales en inglés. Mientras el interés generativo se relacionó con la satisfacción con la vida, los comportamientos generativos no lo hicieron. Sin embargo, ambas esca-las sí se relacionaron con la orientación al futuro, aunque esta relación no se confirmó en un análisis multivariable. Los resultados resaltan la importancia de la generatividad en la vejez y de distinguir entre interés y acción generati-va, ya que sus beneficios podrían ser muy diferentes.

Major mite allergen Der f 1 concentration is reduced in buildings with improved energy performance.

BACKGROUND: Environmental conditions play a crucial role in mite growth, and optimal environmental control is key in the prevention of airway inflammation in chronic allergic rhinoconjunctivitis or asthma. OBJECTIVE: To evaluate the relationship between building energy performance and indoor mite allergen concentration in a cross-sectional study. METHODS: Major allergen concentration (Der f 1, Der p 1, mite group 2, Fel d 1 and Bla g 2) was determined by quantitative dot blot analysis from mattress and carpet dust samples in five buildings designed for low energy use (LEB) and in six control buildings (CB). Inhabitants had received 4 weeks prior to mite measurement a personal validated questionnaire related to the perceived state of health and comfort of living. RESULTS: Cumulative mite allergen concentration (with Der f 1 as the major contributor) was significantly lower in LEB as compared with CB both in mattresses and in carpets. In contrast, the two categories of buildings did not differ in Bla g 2 and Fel d 1 concentration, in the amount of dust and airborne mould collected. Whereas temperature was higher in LEB, relative humidity was significantly lower than in CB. Perceived overall comfort was better in LEB. CONCLUSIONS: Major mite allergen Der f 1 preferentially accumulates in buildings not specifically designed for low energy use, reaching levels at risk for sensitization. We hypothesize that controlled mechanical ventilation present in all audited LEB may favour lower air humidity and hence lower mite growth and allergen concentration, while preserving optimal perceived comfort.

Predicting chick body mass by artificial intelligence-based models

The objective of this work was to develop, validate, and compare 190 artificial intelligence-based models for predicting the body mass of chicks from 2 to 21 days of age subjected to different duration and intensities of thermal challenge. The experiment was conducted inside four climate-controlled wind tunnels using 210 chicks. A database containing 840 datasets (from 2 to 21-day-old chicks) - with the variables dry-bulb air temperature, duration of thermal stress (days), chick age (days), and the daily body mass of chicks - was used for network training, validation, and tests of models based on artificial neural networks (ANNs) and neuro-fuzzy networks (NFNs). The ANNs were most accurate in predicting the body mass of chicks from 2 to 21 days of age after they were subjected to the input variables, and they showed an R² of 0.9993 and a standard error of 4.62 g. The ANNs enable the simulation of different scenarios, which can assist in managerial decision-making, and they can be embedded in the heating control systems.

The marmora used in the imperial cult area of Tarraco (Hispania Citerior)

The imperial cult area of Tarraco was built in the 1st century AD in the highest part of the city and presided over the seat of the Concilium Prouinciae Hispaniae Citerioris. It was a temenos with a similar layout to that of the Forum Pacis and architectural decoration imitating that of the Forum Augustum in Rome, where the use of marble was a fundamental part of the architectural and sculptural decorative programme. An extensive assemblage of marble was recovered during the excavations carried out under the Tarragona Cathedral Master Plan. It reflects the use of imperial quarries in the decorative programme and has been analyzed at the Unitat d’Estudis Arqueomètrics (ICAC) facilities. This assemblage reflects the wide panorama of marmora imported and used in the decoration of the temenos. Local varieties of marmora have been identified in Tarraco, plus a series of foreign marmora from quarries all over the Roman Empire (Greece, Turkey, Egypt and North Africa). All this shows the involvement of the imperial power in the monumental architecture of the capital of the prouincia Hispania Citerior.

Un nuevo problema en espacios verdes urbanos: el pulgón Myzocallis (Lineomyzocallis) walshii (Hemiptera: Aphididae) y el roble americano (Quercus rubra)

Myzocallis (Lineomyzocallis) walshii (Monell) es un pulgón nativo del este de Nor- teamérica que se detectó por primera vez en España en 1995 y cuyo principal huésped es el roble americano (Quercus rubra L.). Los robles americanos se emplean como árbol ornamental en ambientes urbanos en diversas ciudades españolas, donde las proliferaciones del pulgón generan gran cantidad de melaza provocando daños estéticos y de confort. Durante 2008 y 2009 se efectuó el seguimiento de la fenología y de la densidad de población de M. walshii y de otros pulgones en robles americanos plantados en alineación en la ciudad de Girona y se estimaron los daños producidos. Asimismo se valoró la relación entre la abundancia de pulgones y los daños ocasionados. Finalmente se identificaron los principales grupos de enemigos naturales, a la vez que se cuantificó su abundancia. M. walshii fue la única especie de pulgón que afectó a los robles americanos. Este pulgón pasa el invierno en forma de huevo, las primeras ninfas surgen a la salida de hojas y las distintas generaciones de individuos partenogenéticos se mantienen a niveles variables hasta mediados de otoño, cuando aparecen las formas sexuales. Existe una correlación positiva entre la abundancia del pulgón y los daños de confort, incluso cuando la densidad es baja. Parasitoides y coccinélidos fueron los enemigos naturales más frecuentemente registrados, aunque su abundancia fue relativamente escasa. Se discute el papel de las condiciones climáticas y de los enemigos naturales en la determinación de la abundancia de M. walshii.

L'educacio social al llindar del segle XXI

L'estat del benestar neix amb l'industrialisme dels anys 50 i amb l'organització que se'n va derivar. Tot i que el nou missatge del benestar va ser rebutjat per algunes filosofies de substrat existencialista i criticat per part de determinades posicions sociològiques, el cert és que, per primera vegada a la història de l'home, es va pensar, es va parlar i es va gestionar a favor d'una «societat del benestar». A més, aquest innovador estil d'organització política i social va afectar gairebé tots els àmbits de la vida occidental. La investigació científica, el progrés de les ciències socials, la superació d'alguns vells valors i les incerteses que l'apogeu industrial va comportar per a la convivència humana van ser algunes de les novetats culturals lligades al fenomen del benestar.

Responses to a crisis: FASA-Renault in Spain during the 1970s

[cat] Aquest treball analitza la trajectòria de l’empresa FASA-Renault durant la dècada dels setanta del segle XX. Aquest període compren els primers anys de la crisis experimentada per l’economia i la industria espanyola entre 1974 y 1985. A nivell extern, l’economia espanyola es va veure afectada per dos xocs en el preu del petroli. A nivell intern, la industria de l’automòbil es va veure afectat per un decret governamental: es tractava de l’anomenat decret “Ford”, aprovat l’any 1972, el qual facilitava l’establiment de Ford a Espanya. Aquest decret va tenir greus conseqüències per a SEAT, el principal productor espanyol. Entre 1972 y 1980 la producció de SEAT es va reduir en una tercera part i la seva situació financera va esdevenir insostenible. Per contra, en aquest període FASA-Renault va esdevenir el principal productor ubicat a Espanya (la seva producció es va multiplicar per 3,5 durant els anys setanta) i en líder de ventes en el mercat espanyol (la seva penetració es va incrementar del 23 al 36%). El principal objectiu del treball es analitzar els factor que expliquen l’èxit de FASARenault durant els anys setanta.

Reasons to use e-cigarettes and associations with other substances among adolescents in Switzerland.

BACKGROUND: The objectives of this research were to describe the main reason(s) why adolescents use electronic cigarettes, to assess how e-cigarette experimenters and users differ based on personal characteristics, and to determine whether its use is associated with the use of other substances among a representative sample of youths in Switzerland. METHODS: A representative sample of 621 youths (308 females) was divided into never users (n=353), experimenters (Only once, n=120) and users (Several times, n=148) of e-cigarettes. Groups were compared on socio-demographic data and current smoking, alcohol misuse and cannabis use. Reasons for e-cigarette use were compared between experimenters and users. A multinomial regression was performed using never users as the reference category. RESULTS: Forty-three percent had ever tried e-cigarettes, and the main reason was curiosity. Compared to never users, experimenters were more likely to be out of school (Relative Risk Ratio [RRR]: 2.68) and to misuse alcohol (RRR: 2.08), while users were more likely to be male (RRR: 2.75), to be vocational students (RRR: 2.30) or out of school (RRR: 3.48) and to use any of the studied substances (tobacco, RRR: 5.26; alcohol misuse, RRR: 2.71; cannabis use, RRR: 30.2). CONCLUSIONS: Although often still part of adolescent experimentation, e-cigarettes are becoming increasingly popular among adolescents and they should become part of health providers' standard substance use screening. As health providers (and especially paediatricians) do not seem to have high levels of knowledge and, consequently, little comfort in discussing e-cigarettes, training in this domain should be available to them.

Vesikiertoisen ja kaapeleilla toteutetun lattialämmityksen teknistaloudellinen vertailu

Lopputyössä vertailtiin vesikiertoisen ja kaapeleilla toteutetun lattialämmityksen erilai-sia ominaisuuksia. Vertailuparametreinä olivat lattialämmitysten mitoitus, säätö, asen-nus, investointikustannukset, käyttökustannukset, vikaantuminen ja korjaus, asumis-viihtyvyys, käyttöön liittyvät tekijät, markkinat ja toimijat sekä lattian päällysteet. Näistä lat-tialämmityksien asumisviihtyvyys, säätö ja kustannukset otettiin tarkempaan vertailuun. Lämmitysjärjestelmien kokonaiskustannuksia vertailtiin 25 vuoden jaksolla ja 4 % ko-rolla. Investointikustannuksiin sisältyi lämmitysjärjestelmien lisäksi lkv-varaajan ja tek-nisen tilan kustannukset sekä liittymismaksut. Käyttökustannusten vertailussa otettiin huomioon lämmityskulujen lisäksi myös lämmityksen hyötysuhde, yö- ja päiväsähköosuudet ja -energian hinnat, taloussähkön kustannukset, perusmaksut sekä huoltokulut. Tutkimuksen mukaan halvin pientalojen lämmitysmuoto on osittain varaava huonekoh-tainen sähkölämmitys, jonka vuosittaisiksi kustannuksiksi tuli 11452 mk. Sähkölämmi-tyksen tekee vertailtavista halvimmaksi lämmitysjärjestelmäksi pientaloille (n. 150 m2) sen pienet pääomakustannukset, lämmityksen hyvä hyötysuhde sekä varsin kilpailuky-kyiset käyttökustannukset. Vertailun kallein oli öljyä energialähteenä käyttävä vesikiertoi-nen lattialämmitys, jonka vuosittaisiksi kustannuksiksi tuli 13080 mk. Öljy on energia-hinnaltaan halpa, mutta öljylämmityksen huono hyötysuhde sekä varsin korkeat pää-omakustannukset tekevät siitä vertailtavista kalleimman lämmitysmuodon. Energian hin-tojen herkkyysanalyysissä huomattiin sähkön säilyttävän kilpailukykynsä, vaikka öljyn ja maakaasun hinnat laskisivatkin huomattavasti. Asumismukavuuden ja säädön kohdalla vertailtiin lämpötilojen tasaisuutta huonetilois-sa. Mittauskohteiden huonelämpötiloja on seurattu eri projekteissa jatkuvatoimisesti jo-pa yli kahden vuoden ajan. Mittaustulosten mukaan vesikiertoisella lattialämmityksellä huonelämpötilat ovat tasaisemmat kuin osittain varaavalla huonekohtaisella sähköläm-mityksellä. Tämä johtuu sähkölämmityksen varaavuudesta. Hyvillä yhdistelmätermostaateilla päästään tosin myös huonekohtaisen sähkölämmityksen yhteydessä tasaisiin huonelämpötiloihin. Molempien lämmitysmuotojen säädön heikkoutena on hidas reagointi sisäisten lämmönlähteiden aiheuttamaan nopeaan sisälämpötilan nousuun.

Emerging environmental and weather challenges in outdoor sports

Given the climatic changes around the world and the growing outdoor sports participation, existing guidelines and recommendations for exercising in naturally challenging environments such as heat, cold or altitude, exhibit potential shortcomings. Continuous efforts from sport sciences and exercise physiology communities aim at minimizing the risks of environmental-related illnesses during outdoor sports practices. Despite this, the use of simple weather indices does not permit an accurate estimation of the likelihood of facing thermal illnesses. This provides a critical foundation to modify available human comfort modeling and to integrate bio-meteorological data in order to improve the current guidelines. Although it requires further refinement, there is no doubt that standardizing the recently developed Universal Thermal Climate Index approach and its application in the field of sport sciences and exercise physiology may help to improve the appropriateness of the current guidelines for outdoor, recreational and competitive sports participation. This review first summarizes the main environmental-related risk factors that are susceptible to increase with recent climate changes when exercising outside and offers recommendations to combat them appropriately. Secondly, we briefly address the recent development of thermal stress models to assess the thermal comfort and physiological responses when practicing outdoor activities in challenging environments.

Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases

Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned and operated upon with the guided surgery technique. Results: A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complications comprised a lack of primary stability, while the postoperative complications consisted of infections and a lack of implant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of the provisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. The degree of patient satisfaction was evaluated using a verbal scale. Conclusions: Implant restoration with the guided surgery technique and immediate functional loading is a predictable procedure, provided patient selection and the surgical technique are adequate, affording lesser postoperative morbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and function

Hedonisme, benestar i depressió

El juny del 2012, el M. Hble. Jordi Pujol deia, en un dels articles que publica aquest diari, que des de mitjan dècada del 1970 l"enfortiment de l"estat del benestar ha fet que hàgim entrat en una etapa hedonista, en què"el plaer, i no el propòsit d"una societat millor i més justa i l"esforç que això reclama, [...] és la raó principal de la vida". Fa just una setmana, un informe de l"OMS alertava que la depressió és la primera causa de malaltia i discapacitat en els adolescents, i el suïcidi és la segona causa de mort entre els joves de 15 a 19 anys-la primera a Catalunya i entre les noies-. Un treball que s'acaba de publicar a la revista PNAS suggereix que aquests dos fets, l"hedonisme social i la depressió en els adolescents, podrien estar connectats.

Tumour biology, metastatic sites and taxanes sensitivity as determinants of eribulin mesylate efficacy in breast cancer: results from the ERIBEX retrospective, international, multicenter study.

BACKGROUND: Our retrospective, international study aimed at evaluating the activity and safety of eribulin mesylate (EM) in pretreated metastatic breast cancer (MBC) in a routine clinical setting. METHODS: Patients treated with EM for a locally advanced or MBC between March 2011 and January 2014 were included in the study. Clinical and biological assessment of toxicity was performed at each visit. Tumour response was assessed every 3 cycles of treatment. A database was created to collect clinical, pathological and treatment data. RESULTS: Two hundred and fifty-eight patients were included in the study. Median age was 59 years old. Tumours were Hormone Receptor (HR)-positive (73.3 %) HER2-positive (10.2 %), and triple negative (TN, 22.5 %). 86.4 % of the patients presented with visceral metastases, mainly in the liver (67.4 %). Median previous metastatic chemotherapies number was 4 [1-9]. Previous treatments included anthracyclines and/or taxanes (100 %) and capecitabine (90.7 %). Median number of EM cycles was 5 [1-19]. The relative dose intensity was 0.917. At the time of analysis (median follow-up of 13.9 months), 42.3 % of the patients were still alive. The objective response rate was 25.2 % (95 %CI: 20-31) with a 36.1 % clinical benefit rate (CBR). Median time to progression (TTP) and overall survival were 3.97 (95 %CI: 3.25-4.3) and 11.2 (95 %CI: 9.3-12.1) months, respectively. One- and 2-year survival rates were 45.5 and 8.5 %, respectively. In multivariate analysis, HER2 positivity (HR = 0.29), the presence of lung metastases (HR = 2.49) and primary taxanes resistance (HR = 2.36) were the only three independent CBR predictive factors, while HR positivity (HR = 0.67), the presence of lung metastases (HR = 1.52) and primary taxanes resistance (HR = 1.50) were the only three TTP independent prognostic factors. Treatment was globally well tolerated. Most common grade 3-4 toxicities were neutropenia (20.9 %), peripheral neuropathy (3.9 %), anaemia (1.6 %), liver dysfunction (0.8 %) and thrombocytopenia (0.4 %). Thirteen patients (5 %) developed febrile neutropenia. CONCLUSION: EM is an effective new option in heavily pretreated MBC, with a favourable efficacy/safety ratio in a clinical practice setting. Our results comfort the use of this new molecule and pledge for the evaluation of EM-trastuzumab combination in this setting. Tumour biology, primary taxanes sensitivity and metastatic sites could represent useful predictive and prognostic factors.

Proportionality and Party Success in Europe

This thesis consists of four articles and an introductory section. The main research questions in all the articles are about proportionality and party success in Europe, at European, national or district levels. Proportionality in this thesis denotes the proximity of seat shares parties receive compared to their respective vote shares, after the electoral system’s allocation process. This proportionality can be measured through numerous indices that illustrate either the overall proportionality of an electoral system or a particular election. The correspondence of a single party’s seat shares to its vote shares can also be measured. The overall proportionality is essential in three of the articles (1, 2 and 4), where the system’s performance is studied by means of plots. In article 3, minority party success is measured by advantage-ratios that reveal single party’s winnings or losses in the votes to seat allocation process. The first article asks how proportional are the European parliamentary (EP) electoral systems, how do they compare with results gained from earlier studies and how do the EP electoral systems treat different sized parties. The reasons for different outcomes are looked for in explanations given by traditional electoral studies i.e. electoral system variables. The countries studied (EU15) apply electoral systems that vary in many important aspects, even though a certain amount of uniformity has been aspired to for decades. Since the electoral systems of the EP elections closely resemble the national elections, the same kinds of profiles emerge as in the national elections. The electoral systems indeed treat the parties differentially and six different profile types can be found. The counting method seems to somewhat determine the profile group, but the strongest variables determining the shape of a countries’ profile appears to be the average district magnitude and number of seats allocated to each country. The second article also focuses on overall proportionality performance of an electoral system, but here the focus is on the impact of electoral system changes. I have developed a new method of visualizing some previously used indices and some new indices for this purpose. The aim is to draw a comparable picture of these electoral systems’ changes and their effects. The cases, which illustrate this method, are four elections systems, where a change has occurred in one of the system variables, while the rest remained unchanged. The studied cases include the French, Greek and British European parliamentary systems and the Swedish national parliamentary system. The changed variables are electoral type (plurality changed to PR in the UK), magnitude (France splitting the nationwide district into eight smaller districts), legal threshold (Greece introducing a three percent threshold) and counting method (d’Hondt was changed to modified Sainte-Laguë in Sweden). The radar plots from elections after and before the changes are drawn for all country cases. When quantifying the change, the change in the plots area that is created has also been calculated. Using these radar plots we can observe that the change in electoral system type, magnitude, and also to some extent legal threshold had an effect on overall proportionality and accessibility for small parties, while the change between the two highest averages counting method had none. The third article studies the success minority parties have had in nine electoral systems in European heterogeneous countries. This article aims to add more motivation as to why we should care how different sized parties are treated by the electoral systems. Since many of the parties that aspire to represent minorities in European countries are small, the possibilities for small parties are highlighted. The theory of consociational (or power-sharing) democracy suggests that, in heterogeneous societies, a proportional electoral system will provide the fairest treatment of minority parties. The OSCE Lund Recommendations propose a number of electoral system features, which would improve minority representation. In this article some party variables, namely the unity of the minority parties and the geographical concentration of the minorities were included among possible explanations. The conclusions are that the central points affecting minority success were indeed these non-electoral system variables rather than the electoral system itself. Moreover, the size of the party was a major factor governing success in all the systems investigated; large parties benefited in all the studied electoral systems. In the fourth article the proportionality profiles are again applied, but this time to district level results in Finnish parliamentary elections. The level of proportionality distortion is also studied by way of indices. The average magnitudes during the studied periodrange from 7.5 to 26.2 in the Finnish electoral districts and this opens up unequal opportunities for parties in different districts and affects the shape of the profiles. The intra-country case allows the focus to be placed on the effect of district magnitude, since all other electoral systems are kept constant in an intra-country study. The time span in the study is from 1962 to 2007, i.e. the time that the districts have largely been the same geographically. The plots and indices tell the same story, district magnitude and electoral alliances matter. The district magnitude is connected to the overall proportionality of the electoral districts according to both indices, and the profiles are, as expected, also closer to perfect proportionality in large districts. Alliances have helped some small parties to gain a much higher seat share than their respective vote share and these successes affect some of the profiles. The profiles also show a consistent pattern of benefits for the small parties who ally with the larger parties.
