Universal Museum - universal language? Art historian - curator

Marshal McLuhan’s prophetic vision of the global village is about to be realized. If we are aware of the fact that mass communication reduces the dimensions of our world and makes it more unified and universal, we should take this into consideration when planning the Universal Museum and the language that should be used in it. As curators, educators and museum staff we should not ignore the fact that the spectator/viewer is drawn to the exhibits not only by their own merit, but also guided and assisted by verbal messages, i. e. Labels, brochures. Catalogues etc. Hence, the crucial question is what we, the museologists, use as a means of communication when preparing for a Universal Museum. Should we use pictorial semiotics? This may be a partial solution, which is mainly restricted to objects that can be manipulated and moved by the visitor, as is the case in most of the technological museums. But since the range of objects on display at museums is vast and varied - fine art, archaeological finds, ethnographic objects etc., it may not be the answer to the whole spectrum of exhibits. Dr. Ludwig Lazarus Zamenhof, being an optimist, hoped that by introducing Esperanto to the multi-lingual world population, humanity would be able to bridge and diminish the gap of linguistic differences, thus creating a better understanding between the international communities. Unfortunately this vision was not realized. Esperanto was and still is an utopian and esoteric phenomenon. The barriers between nations still exist although, as mentioned earlier, mass media do help, in some ways, to reduce them.

Brand equity : o valor da marca

O trabalho desenvolvido objetiva identificar e descrever comportamentos e reações de consumidores face às percepções de marcas. A partir de suas percepções sobre as marcas estudadas, são identificados os principais traços que compõem suas personalidades e, diante disso, são estudadas as reações mercadológicas derivadas da relações emocionais existentes entre marca e consumidor. A conjunção de teorias propostas, sobretudo pela psicologia e pelas terias de administração de marcas, somadas ao pensamento implícito à teoria da estratégia de diferenciação de Michael Porter, representam a síntese da proposta para os trabalhos" aqui desenvolvidos. Para ilustrar e validar a metodologia proposta será apresentado um estudo de caráter qualitativo, representando elementos das decisões de adoção de marcas dentro do setor têxtil, focando- as estratégias de aquisição de licenças internacionais, conhecidas e consolidadas, objetivando o fortalecimento do share no mercado brasileiro. Como veremos a seguir, o uso apropriado de marcas já "maduras" cria oportunidades de se destacar frente a mercados altamente competitivos e onde há poucas oportunidades de diferenciação de produtos, sendo portanto ideal para a sua aplicação no setor apresentado, o têxtil, por ser caracterizado por sua dificuldade em apresentar diferenciações dos produtos frente a concorrência, onde as coleções lançadas são muito semelhantes entre si, e onde os critérios objetivo tais como o de modelagem, matéria I prima, qualidade de acabamento, etc, passam a serem preteridos ao consumidor final frente a critérios subjetivos tais como a roupa da moda, a marca do momento

Dati geochimici ed ecologici di foraminiferi planctonici. Implicazioni paleoceanografiche in due aree chiave: Oceano Meridionale e Mare Mediterraneo.

La studio della distribuzione spaziale e temporale della associazioni a foraminiferi planctonici, campionati in zone con differente regime idrografico, ha permesso di comprendere che molte specie possono essere diagnostiche della presenza di diverse masse d’acqua superficiali e sottosuperficiali e di diversi regimi di nutrienti nelle acque oceaniche. Parte di questo lavoro di tesi si basa sullo studio delle associazioni a foraminiferi planctonici attualmente viventi nel Settore Pacifico dell’Oceano Meridionale (Mare di Ross e Zona del Fronte Polare) e nel Mare Mediterraneo (Mar Tirreno Meridionale). L’obiettivo di questo studio è quello di comprendere i fattori (temperatura, salinità, nutrienti etc.) che determinano la distribuzione attuale delle diverse specie al fine di valutarne il valore di “indicatori” (proxies) utili alla ricostruzione degli scenari paleoclimatici e paleoceanografici succedutisi in queste aree. I risultati documentano che la distribuzione delle diverse specie, il numero di individui e le variazioni nella morfologia di alcuni taxa sono correlate alle caratteristiche chimico-fisiche della colonna e alla disponibilità di nutrienti e di clorofilla. La seconda parte del lavoro di tesi ha previsto l’analisi degli isotopi stabili dell’ossigeno e del rapporto Mg/Ca in gusci di N. pachyderma (sin) prelevati da pescate di micro zooplancton (per tarare l’equazione di paleo temperatura) da un box core e da una carota provenienti dalla zona del Fronte Polare (Oceano Pacifico meridionale), al fine di ricostruire le variazioni di temperatura negli ultimi 13 ka e durante la Mid-Pleistocene Revolution. Le temperature, dedotte tramite i valori degli isotopi stabili dell’ossigeno, sono coerenti con le temperature attuali documentate in questa zona e il trend di temperatura è paragonabile a quelli riportati in letteratura anche per eventi climatici come lo Younger Dryas e il mid-Holocene Optimum. I valori del rapporto Mg/Ca misurato tramite due diverse tecniche di analisi (laser ablation e analisi in soluzione) sono risultati sempre molto più alti dei valori riportati in letteratura per la stessa specie. La laser ablation sembra carente dal punto di vista del cleaning del campione e da questo studio emerge che le due tecniche non sono comparabili e che non possono essere usate indifferentemente sullo stesso campione. Per quanto riguarda l’analisi dei campioni in soluzione è stato migliorato il protocollo di cleaning per il trattamento di campioni antartici, che ha permesso di ottenere valori veritieri e utili ai fini delle ricostruzioni di paleotemperatura. Tuttavia, rimane verosimile l’ipotesi che in ambienti particolari come questo, con salinità e temperature molto basse, l’incorporazione del Mg all’interno del guscio risenta delle condizioni particolari e che non segua quindi la relazione esponenziale con la temperatura ampiamente dimostrata ad altre latitudini.

Effects of Paramuricea clavata (Risso, 1826) (Anthozoa: Plexauridae) forests on settlement of benthic species: an experimental approach

Rationale: Coralligenous habitat is considered the second most important subtidal “hot spot” of species diversity in the Mediterranean Sea after the Posidonia oceanica meadows. It can be defined as a typical Mediterranean biogenic hard bottom, mainly produced by the accumulation of calcareous encrusting algae that, together with other builder organisms, form a multidimensional framework with a high micro-spatial variability. The development of this habitat depends on physical factors (i.e. light, hydrodynamism, nutrients, etc.), but also biologic interactions can play a relevant role in structuring the benthic assemblages. This great environmental heterogeneity allows several different assemblages to coexist in a reduced space. One of the most beautiful is that characterised by the Mediterranean gorgonian Paramuricea clavata (Risso, 1826) that can contribute to above 40% of total biomass of the community and brings significant structural complexity into the coralligenous habitat. In sites moderately exposed to waves and currents, P. clavata can form high-density populations (up to 60 colonies m-2) between 20 – 70 m in depth. Being a suspension feeder, where it forms dense populations, P. clavata plays a significant role in transferring energy from planktonic to benthic system. The effects of the branched colonies of P. clavata could be comparable to those of the forests on land. They can affect the micro scale hydrodynamism and light, promoting or inhibiting the growth of other species. Unfortunately, gorgonians are threatened by several anthropogenic disturbance factors (i.e. fishing, pollution, tourism) and by climatic anomalies, linked to the global changes, that are responsible of thermal stress, development of mucilage and enhanced pathogens activity, leading to mass mortality events in last decades. Till now, the possible effects of gorgonian forest loss are largely unknown. Our goal was to analyse the ecological role of these sea fan forests on the coralligenous benthic assemblages. Experimental setup and main results: The influence of P. clavata in the settlement and recruitment of epibenthic organisms was analysed by a field experiment carried out in two randomly selected places: Tavolara island and Portofino promontory. The experiment consisted in recreate the presence and absence of the gorgonian forest on recruitment panels, arranged in four plots per type (forested and non-forested), interspersed each other, and deployed at the same depth. On every forested panel 3 gorgonian colonies about 20 cm height were grafted with the use of Eppendorf tubes and epoxy resin bicomponent simulating a density of 190 sea fans per m-2. This density corresponds to a mean biomass of 825 g DW m-2,3 which is of the same order of magnitude of the natural high-density populations. After about 4 months, the panels were collected and analysed in laboratory in order to estimate the percent cover of all the species that have colonized the substrata. The gorgonian forest effects were tested by multivariate and univariate permutational analyses of the variance (PERMANOVA). Recruited assemblages largely differed between the two study sites, probably due to different environmental conditions including water quality and turbidity. On overall, the presence of P. clavata reduced the settlement and recruitment of several algae: the shadow caused by the gorgonian might reduce light availability and therefore their growth. This effect might be greater in places where the waters are on average more clear, since at Portofino it is less visible and could be masked by the high turbidity of the water. The same pattern was registered for forams, more abundant outside gorgonian forest, probably linked with algal distribution, shadowing effect or alimentary competition. The last one hypothesis could be valid also for serpulids polychaetes that growth mainly on non-forested panels. An opposite trend, was showed by a species of bryozoan and by an hydroid that is facilitated by the presence of P. clavata, probably because it attenuates irradiance level and hydrodynamism. Species diversity was significantly reduced by the presence of P. clavata forests at both sites. This seems in contrast with what we expected, but the result may be influenced by the large algal component on non-forested panels. The analysis confirmed the presence of differences in the species diversity among plots and between sites respectively due to natural high variability of the coralligenous system and to different local environment conditions. The reduction of species diversity due to the presence of gorgonians appeared related to a worst evenness rather than to less species richness. With our experiment it is demonstrated that the presence of P. clavata forests can significantly alter local coralligenous assemblages patterns, promoting or inhibiting the recruitment of some species, modifying trophic relationships and adding heterogeneity and complexity to the habitat. Moreover, P. clavata could have a stabilising effect on the coralligenous assemblages.

Presenza e diffusione della Leishmaniosi e dei suoi vettori in provincia di Rieti

Nel presente studio ci si è proposti di valutare la presenza e diffusione della leishmaniosi in una provincia dell’Italia centrale (Rieti) che, per caratteristiche ambientali (prevalentemente montuosa, clima freddo-secco) poco sembra prestarsi al ciclo della malattia. A questo scopo sono stati calcolati: i) sieroprevalenza grezza nella popolazione canina (2006-2013) e prevalenza media annuale ii) casi di leishmaniosi viscerale (LV) e cutanea (LC) (2000-2013). Catture di flebotomi sono state effettuate per due stagioni consecutive (2011-2012) per ogni sito sono stati registrati i dati climatici (temperatura, umidità etc.) ed altitudine. I flebotomi sono stati sottoposti a ricerca di Leishmania mediante PCR. La sieroprevalenza grezza per leishmania varia da 0 a 76,9% e la prevalenza media annuale non presenta un trend lineare. Sono stati registrati 6 casi di LV tutti in pazienti italiani tutti residenti in provincia di Rieti. I flebotomi sono stati rilevati in 5 dei 6 siti monitorati fino agli 800 m s.l.m., seppur con basse densità. Sono state identificate le seguenti specie: P. perniciosus (6,4 %), P. perfiliewi (1,8%), P. mascittii (0,1%) e S. minuta (91,7 %). E’ stata rilevata una correlazione statisticamente significativa (r=0,69, p<0,001) tra numero di flebotomi e temperatura giornaliera (Tmed°C) ed una correlazione negativa significativa (r= -0,51, p<0,05) con l’umidità relativa (Umed%). La ricerca di leishmania ha dato esito negativo in tutti i flebotomi analizzati. Questi rilievi suggeriscono l’endemia della leishmaniosi nella provincia di Rieti.

Description of the ERA-CLIM historical upper-air data

Historical, i.e. pre-1957, upper-air data are a valuable source of information on the state of the atmosphere, in some parts of the world dating back to the early 20th century. However, to date, reanalyses have only partially made use of these data, and only of observations made after 1948. Even for the period between 1948 (the starting year of the NCEP/NCAR (National Centers for Environmental Prediction/National Center for Atmospheric Research) reanalysis) and the International Geophysical Year in 1957 (the starting year of the ERA-40 reanalysis), when the global upper-air coverage reached more or less its current status, many observations have not yet been digitised. The Comprehensive Historical Upper-Air Network (CHUAN) already compiled a large collection of pre-1957 upper-air data. In the framework of the European project ERA-CLIM (European Reanalysis of Global Climate Observations), significant amounts of additional upper-air data have been catalogued (> 1.3 million station days), imaged (> 200 000 images) and digitised (> 700 000 station days) in order to prepare a new input data set for upcoming reanalyses. The records cover large parts of the globe, focussing on, so far, less well covered regions such as the tropics, the polar regions and the oceans, and on very early upper-air data from Europe and the US. The total number of digitised/inventoried records is 61/101 for moving upper-air data, i.e. data from ships, etc., and 735/1783 for fixed upper-air stations. Here, we give a detailed description of the resulting data set including the metadata and the quality checking procedures applied. The data will be included in the next version of CHUAN. The data are available at doi:10.1594/PANGAEA.821222

Sleep quality and quantity and associated factors among high school students from south Texas

Background. Insufficient and poor quality sleep among adolescents affects not only the cognitive functioning, but overall health of the individual. Existing research suggests that adolescents from varying ethnic groups exhibit differing sleep patterns. However, little research focuses on sleep patterns and associated factors (i.e. tobacco use, mental health indicators) among Hispanic youth. ^ Methods. The study population (n=2,536) included students in grades 9-12 who attended one of the three public high schools along the Texas-Mexico border in 2003. This was a cross sectional study using secondary data collected via a web-based, confidential, self-administered survey. Separate logistic regression models were estimated to identify factors associated with reduced (<9 hours/night) and poor quality sleep on average during weeknights. ^ Results. Of participants, 49.5% reported reduced sleep while 12.8% reported poor quality sleep. Factors significantly (p<0.05) associated with poor quality sleep were: often feeling stressed or anxious (OR=5.49), being born in Mexico (OR=0.65), using a computer/playing video games 15+ hours per week (OR=2.29), working (OR=1.37), being a current smoker (OR=2.16), and being a current alcohol user (OR=1.64). Factors significantly associated with reduced quantity of sleep were: often feeling stressed or anxious (OR=2.74), often having headaches/stomachaches (OR=1.77), being a current marijuana user (OR=1.70), being a current methamphetamine user (OR=4.92), and being a current alcohol user (OR=1.27). ^ Discussion. Previous research suggests that there are several factors that can influence sleep quality and quantity in adolescents. This paper discusses these factors (i.e. work, smoking, alcohol, etc.) found to be associated with poor sleep quality and reduced sleep quantity in the Hispanic adolescent population. A reduced quantity of sleep (81.20% of the participants) and a poor quality of sleep (12.80% of the participants) were also found in high school students from South Texas. ^

ERA-CLIM Historical Upper-Air Data 1900-1972

Exploring the role of social capital influence variables on travel behaviour

This paper explores the potential role of individual trip characteristics and social capital network variables in the choice of transport mode. A sample of around 100 individuals living or working in one suburb of Madrid (i.e. Las Rosas district of Madrid) participated in a smartphone short panel survey, entering travel data for an entire working week. A Mixed Logit model was estimated with this data to analyze shifts to metro as a consequence of the opening of two new stations in the area. Apart from classical explanatory variables, such as travel time and cost, gender, license and car ownership, the model incorporated two “social capital network” variables: participation in voluntary activities and receiving help for various tasks (i.e. child care, housekeeping, etc.). Both variables improved the capacity of the model to explain transport mode shifts. Further, our results confirm that the shift towards metro was higher in the case of people “helped” and lower for those participating in some voluntary activities.

Ageism in the workplace: Examining the influence of age conceptualization on the advancement opportunities of older workers

This study examined variables that may influence managers' perceptions of the need for and benefits of training and promoting older workers. Age conceptualization, worker gender, tender-mindedness, openness to values, and emotional intelligence were predicted to affect the relationship between worker age and the probability and perceived benefits of training and promoting older workers. Approximately 500 working professionals read one of four training and promotion vignettes and provided training probability ratings, training benefits ratings, promotion probability ratings, and promotion benefits ratings in order to test twenty-four hypotheses. Results provided evidence that both worker age and the way in which age was conceptualized affected the extent to which workers were recommended for training as well as the perceived benefits of training workers. It was also found that worker age and the way in which age was conceptualized affected the extent to which workers were recommended for promotions and the perceived benefits of doing so. Of the individual characteristics studied, openness to values was found to act as a moderator of the relationship between age conceptualization and the extent to which older workers were recommended for a promotion and the relationship between age conceptualization and the perceived benefits of promoting older workers. Findings from this study suggest that organizations that wish to protect older workers from discrimination should make decision-makers aware of the influence of age conceptualizations on the salience of older worker stereotypes. By being cognizant of individual raters' levels of the personality characteristics examined in this study, organizations can create decision-making teams that are not only representative in terms of demographic characteristics (i.e. race, gender, age, etc.) but also diverse in terms of personality composition. Additionally, organizations that wish to decrease discrimination against older workers should take care to create guidelines and procedures for training and promotion decisions that systematically reduce the opportunities for older worker stereotypes to influence outcomes. ^
