description: Este artigo tem como objetivo discutir o uso de ferramentas para análise de conteúdo de postagens do Twitter relativo à perceção, por usuários, da qualidade de produtos e serviços turísticos em eventos. Realizou-se um levantamento de literatura pertinente, com a finalidade de caracterizar o produto turístico, mídias sociais e a análise de conteúdo. Elaborou-se uma estrutura de categorias e itens para a coleta de postagens do Twitter que versassem sobre atitudes demonstradas por usuários relacionadas aos produtos e serviços turísticos disponibilizados para consumo durante os Jogos Olímpicos de Londres 2012. Propôs-se uma estrutura para analisar o conteúdo das informações disseminadas por usuários no Twitter, na qual se explorou a técnica Evaluative Assertion Analysis e ferramentas automáticas disponíveis online. Os 878 tweets derivados da amostra foram inseridos nas ferramentas selecionadas, tendo os resultados obtidos sido comparados com aqueles obtidos pela Evaluative Assertion Analysis. Concluiu-se que ambas as alternativas são viáveis para analisar o conteúdo disponível no Twitter relativo à qualidade de produtos e serviços turísticos em eventos. Ambas as alternativas apresentam convergência nos custos para a sua utilização e divergências nos custos da sua operacionalização, ou seja, no tempo despendido para análise, nos processos analíticos adotados e nos resultados obtidos..

description: Growth of BaMn2As2 crystals using both MnAs and Sn fluxes is reported. Room temperature crystallography, anisotropic isothermal magnetization M versus field H and magnetic susceptibility chi versus temperature T, electrical resistivity in the ab plane rho(T), and heat capacity C(T) measurements on the crystals were carried out. The tetragonal ThCr2Si2-type structure of BaMn2As2 is confirmed. After correction for traces of ferromagnetic MnAs impurity phase using M(H) isotherms, the inferred intrinsic chi(T) data of the crystals are anisotropic with chi_{ab}/chi_{c} \approx 7.5 at T = 2 K. The temperature dependences of the anisotropic chi data suggest that BaMn2As2 is a collinear antiferromagnet at room temperature with the easy axis along the c axis, and with an extrapolated Neel temperature T_N \sim 500 K. The rho(T) decreases with decreasing T below 310 K but then increases below \sim 50 K, suggesting that BaMn2As2 is a small band-gap semiconductor with an activation energy of order 0.03 eV. The C(T) data from 2 to 5 K are consistent with this insulating ground state, exhibiting a low temperature Sommerfeld coefficient gamma = 0.0(4) mJ/mol K^2. The Debye temperature is determined from these data to be theta_D = 246(4) K. BaMn2As2 is a potential parent compound for ThCr2Si2-type superconductors.

description: Social media plays an essential part on today’s marketing campaigns. It gives brands the opportunity to reach a worldwide audience with few resources, trying to influence the consumer decision-making process. In 2012, Porto became the setting of a pilot location based transmedia storytelling experiment – TravelPlot Porto. During twelve weeks, tourists were invited to physically embark on a treasure hunt, while visiting Porto, or virtually on the social networks of the project. This paper analyses the audience behavior on TravelPlot Porto’s social media channels – Facebook, Twitter and YouTube. All social networks reached a high number of users in different countries, indicating a great potential of social media as a tool for the promotion of tourism and in particular location based transmedia storytelling projects.

description: With climate and land use changes, it is becoming increasingly important to understand not only how much carbon is and will be stored in soils, but also how long this C will remain in soils. Estimates of C age can provide useful information about the timescales on which C will respond to such changes. It is generally accepted that the interaction of climate and soil mineralogy have a strong influence on C age. However, our current understanding is primarily based on findings from temperate regions and from small-scale studies. Large knowledge gaps persist in (sub-)tropical regions where soil processes are often understudied.

Here, we use a systematic continental-scale approach to better understand the processes controlling C age on a larger scale in these understudied soils. In total, 510 samples were analyzed for radiocarbon (Δ14C), consisting of topsoils (0–20 cm) and subsoils (20–50 cm) collected from 30 sites across 14 countries. The sampled soils are part of a comprehensive soil survey (AfSIS) for sub-Saharan Africa, for which soil mineralogy (based on X-ray powder diffraction) and soil chemistry were determined.

Soils with the youngest C ages are generally highly weathered, and are characterized by humid climates, high gross primary productivity (GPP), and a dominance of 1:1 clay minerals. In contrast, older C ages are either found in arid regions characterized by low C inputs and low mineral stabilization, or in seasonal climates, where GPP is high but a portion of the C is stabilized by 2:1 clay minerals and poorly crystalline minerals. Cultivation and erosion appear to play a secondary role at this large scale, but widen the range of C ages.

Our data suggest that soils from seasonal climate zones have the most favorable climatic and pedogenic conditions to stabilize and store C. Yet, they are also the most vulnerable climate zones according to future projections for sub-Saharan Africa. Understanding how the stabilizing minerals will react to climate change is key to understanding short and long-term changes in C storage and stabilization.

description: It is well known that the integration among different data-sources is reliable because of its potential of unveiling new functionalities of the genomic expressions which might be dormant in a single source analysis. Moreover, different studies have justified the more powerful analyses of multi-platform data. Toward this, in this study, we consider the circadian genes' omics profile such as copy number changes and RNA sequence data along with their survival response. We develop a Bayesian structural equation modeling coupled with linear regressions and log normal accelerated failure time regression to integrate the information between these two platforms to predict the survival of the subjects. We place conjugate priors on the regression parameters and derive the Gibbs sampler using the conditional distributions of them. Our extensive simulation study shows that the integrative model provides a better fit to the data than its closest competitor. The analyses of glioblastoma cancer data and the breast cancer data from TCGA, the largest genomics and transcriptomics database, support our findings. The developed method is wrapped in R package semmcmc available at R CRAN.

description: Tracing ‘bomb’ radiocarbon produced by atmospheric testing of atomic weapons through vegetation and soils provides information of the dynamics of terrestrial carbon cycling on timescales of years to centuries. Processes operating on these timescales are of interest because they regulate key functions in long-lived plants and regulate the potential for increasing soil carbon storage.  However, the multiple pathways taken by carbon transiting ecosystems from photosynthesis to respiration and decomposition complicate the quantitative interpretation of radiocarbon observations.  In the 14Constraint project, we are exploring how to optimize measurements of radiocarbon as well as to improve their interpretation by providing constraints for comparison with models.   This talk will focus on efforts to synthesize global radiocarbon measurements of mean age and transit time, and suggest ways forward to improve process-level understanding.

Patenting bioprinting : an ethical dilemma in the provision of accessible health technologies
Creators: name: Adesanya, Olumayowa
Publisher: name: University Of Tasmania
Year: 2023

description: For decades, researchers in the tissue engineering and regenerative medicine sphere have continuously worked to replicate naturally occurring tissues and organs for research and transplantation purposes. Whilst this has been met with a certain degree of success, it would appear that many engineered tissue products lack the structural and functional complexity found in their naturally occurring counterparts. To this end, the emergence of bioprinting with its promises to reproduce the complexity and intricacy of native tissues through precise placement of cells marks an important milestone not only in the advancement of tissue engineering, but also for the future of healthcare. In simple terms, bioprinting involves the use of a combination of living biological cells, and other living and non-living materials to print three-dimensional functional living tissue constructs such as breast, liver, kidney and skin tissue. It is anticipated that such bioprinted constructs1 will be used in the areas of disease modelling and research; drug discovery and animal testing; as well as treatment of chronic diseases and tissue/organ transplantation. Given these potential applications of bioprinting, it is pertinent that ethical, legal and socio-economic concerns regarding the technology are fully explored as the technology advances. This is especially so in light of the developing patent landscape for bioprinted constructs which are generally designed to replicate their naturally occurring counterparts - the latter being unpatentable subject matter. Accordingly, this thesis examines the law on patentability of bioprinted constructs (which are combinations of living and non-living materials) and questions whether they ought to be patentable given the implications of monopolising body parts. In particular, this thesis focuses on three jurisdictions with disparate approaches to patentability ‚Äö- Australia, Europe (under the European Patent Convention) and the United States of America. It considers whether the disparate approaches to patentable subject matter and morality of patenting yield similar or different results. Noting that the differences in legislative provisions appear to have limited impact on patentability, this thesis also considers the parameters of access to patented bioprinted constructs. It examines matters pertaining to access to bioprinted constructs in themselves, as well as access to the technology. In this regard, this thesis concludes that patent flexibilities in their current form are not particularly suited to the nature of bioprinted constructs. Accordingly, ensuring technological access is especially important in order to ameliorate the effects of a patent grant and ensure equitable access for all.

description: We report the first direct detection of molecular hydrogen associated with the Galactic nuclear wind. The Far-Ultraviolet Spectroscopic Explorer spectrum of LS 4825, a B1 Ib-II star at $l,b$ = 1.67$^{\circ}$,$-$6.63$^{\circ}$ lying $d$ = 9.9$^{+1.4}_{-0.8}$ kpc from the Sun, $\sim$1 kpc below the Galactic plane near the Galactic Center, shows two high-velocity H$_2$ components at $v_\mathrm{LSR}$ = $-79$ and $-108$ km s$^{-1}$. In contrast, the FUSE spectrum of the nearby ($\sim$0.6$^{\circ}$ away) foreground star HD 167402 at $d$=4.9$^{+0.8}_{-0.7}$ kpc reveals no H$_2$ absorption at these velocities. Over 60 lines of H$_2$ from rotational levels $J$ = 0 to 5 are identified in the high-velocity clouds. For the $v_\mathrm{LSR}$ = $-79$ km s$^{-1}$ cloud we measure total log $N$(H$_2$) $\geq$ 16.75 cm$^{-2}$, molecular fraction $f_\mathrm{H_2}$ $\geq$ 0.8%, and $T_{01}$ $\geq$ 97 and $T_{25}$ $\leq$ 439 K for the ground- and excited-state rotational excitation temperatures. At $v_\mathrm{LSR}$ = $-108$ km s$^{-1}$, we measure log $N$(H$_2$) = 16.13 $\pm$ 0.10 cm$^{-2}$, $f_\mathrm{H_2}$ $\geq$ 0.5%, and $T_{01}$ = 77$^{+34}_{-18}$ and $T_{25}$ = 1092$^{+149}_{-117}$ K, for which the excited state ortho- to para-H$_2$ is 1.0$^{+0.3}_{-0.1}$, much less than the equilibrium value of 3 expected for gas at this temperature. This non-equilibrium ratio suggests that the $-108$ km s$^{-1}$ cloud has been recently excited and has not yet had time to equilibrate. As the LS 4825 sight line passes close by a tilted section of the Galactic disk, we propose that we are probing a boundary region where the nuclear wind is removing gas from the disk.

title: Lifestyle as a Determinant of Participation Among Dispersed Forest Recreationists
Creators: name: Butler, John R.
Publisher: name: Utah State University
Year: 1981

description: This study assesses the usefulness of lifestyle as a determinant of outdoor recreation behavior. Two objectives of the study are: (1) develop an operationalized concept of lifestyle that is based on theory, and (2) apply this concept in a model which uses lifestyle as a variable influencing recreation behavior.
The first objective was approached through an integrative review of the literature. Lifestyle was set in context of cultural theory. The basic postulate of the proposed theory of lifestyle is: If an individual's lifestyle is similar to that of another, certain social psychological processes are similar. Therefore, their patterns of needs, motivations, and expectations are similar. Individual's value profiles were proposed as an approach to measuring lifestyle. A model was then proposed to test this.
Two hundred and forty-three dispersed road recreationists were interviewed at three National Forest study areas. Of these 157 responded to a follow-up mail survey. Recreation behavior measures (primary activities and experience expectations) were gathered on site. Lifestyle data was gathered in the mail survey.
The results indicate that lifestyle groups may be identified among dispersed road recreationists. However, tests of the model found no relationships between lifestyle group and primary activity, and few relationships between lifestyle group and experience expectations. Some problems with the methods, due to the exploratory nature of the study, are suggested as explanations for failure of the model. An analysis of the individual value dimensions, as an alternative to value profiles, suggests possible support for values as determinants of experience expectations.

description: Location based transmedia storytelling projects have been recently applied to tourism. They use several communication platforms, each with different objectives and targeting different types of users. These projects have the ability to connect ancient human experiences such as storytelling and games along with locative media, allowing users to explore locations, which are unfamiliar to them. This paper analyses the TravelPlot Porto case study, specifically the behavior on its two main platforms, the website and the mobile application. Despite being an isolated case study, the results have been encouraging, revealing the audiences interest for location based transmedia storytelling projects, and contribute to a better understanding of gains obtained through the integrated use of several platforms.

Lithogenic particle flux to the subantarctic Southern Ocean : a multi-tracer estimate using sediment trap samples
Creators: name: Traill, CD
Publisher: name: University Of Tasmania
Year: 2023

description: The delivery of lithogenic material from atmospheric dust to remote regions of the Southern Ocean is thought to be a key source of micronutrients, particularly iron, essential for phytoplankton. Here, we present a time series of lithogenic flux estimates from 2010 to 2019 using sinking particles collected by sediment traps at 1000m at the Southern Ocean Time Series mooring station in the subantarctic Southern Ocean. Lithogenic flux estimates were made based on aluminium, titanium, iron and thorium concentration in sinking particles and showed good agreement with one another. A multi-tracer flux estimate was calculated using an average of all individual tracer flux estimates in order to reduce biases associated with each element's reactivity in seawater. This mean lithogenic flux exhibited a strong seasonality, with two peaks in late spring and in summer. The magnitude of our multi-tracer lithogenic flux was comparable to previous sediment trap-based fluxes reported in the Southern Ocean and to 230Th-normalised lithogenic fluxes from core-top sediments at the same study location. A lack of lithogenic tracer enrichment in our samples compared to the average upper continental crust values indicated that lithogenic material dominates iron supply in this region. Sinking particle samples from SOTS showed similar Fe enrichment to aerosols collected over southern marine regions around Australia, suggesting that Australian dust may be the primary lithogenic source to SOTS sinking particles. Evidence of lead (Pb) enrichment in sediment trap samples at 1000m highlighted a non-negligible contribution from anthropogenic particles in SOTS sediments, the later source which could represent a secondary Fe supply to the samples. Therefore, we concluded that aeolian emissions from Australia likely compose the primary source of lithogenic particles to SOTS subantarctic Southern Ocean 1000m-deep waters. This hypothesis was further supported by maximum lithogenic particle flux at 1000m depth in late spring preceded by seasonal atmospheric aerosol loading from aerosol optical depth and satellite reanalysis modelled dust deposition maxima that occurred during the Australian dust storm season in spring across the study period. While carbon export at 1000m showed good correlation with surface chlorophyll concentrations at SOTS across the study period, a lack of linear relationship between lithogenic fluxes at 1000m and productivity leaves the link between marine productivity and 1000m-deep sinking particles in this subantarctic region of the Southern Ocean unclear.

Análise estratégica do mercado emissor chinês em Portugal

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: O turismo emissor da República Popular da China, embora com um atraso considerável face ao boom turístico ocorrido no período pós-2ª Guerra Mundial, registou um crescimento exponencial a partir 1983 e alcançou o título de maior mercado emissor à escala mundial, em 2012, com mais de 83 milhões de cidadãos chineses a realizarem viagens de âmbito internacional. Embora este crescimento apresente resultados mais significativos em destinos asiáticos, nomeadamente no Sudeste Asiático, as viagens internacionais de longa distância são, cada vez mais, uma realidade. Neste contexto, a Europa posiciona-se como um destino de eleição, pela ulticulturalidade apresentada, embora seja a região de destino para ‘apenas’ 4% da totalidade do mercado chinês. Simultaneamente, poucos são os países europeus que se destacam enquanto recetores de turistas chineses – Rússia, Reino Unido, Alemanha e França. Portugal, por sua vez, motivou a visita de 52 mil chineses, em 2012, mas as ligações históricas com a Ásia e as recentes parcerias económicas sino-portuguesas podem estimular o crescimento deste mercado. Desta forma, o presente artigo pretende efetuar uma análise referente à evolução do mercado emissor chinês em Portugal e, posteriormente, delinear um conjunto de potenciais estratégias para a promoção de Portugal e a captação de fluxos turísticos chineses.

Comportamento espácio-temporal do turista urbano: o impacte da duração da estada

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: O comportamento espácio-temporal dos turistas é um fenómeno complexo, influenciado por inúmeros fatores relativos quer aos turistas quer ao próprio destino. No entanto, conhecer e, até certo ponto, gerir a forma como os turistas se movem no espaço e no tempo é crucial para assegurar a qualidade da sua experiência, bem como a gestão eficaz e sustentável de destinos e atrações. Sobretudo, com base em estudos relativos à viagem multidestino, há evidência de que os constrangimentos temporais são um dos fatores mais influentes sobre o itinerário e a atividade espaço-tempo dos turistas. Isto porque, em presença de um orçamento temporal reduzido, o turista tende a querer tirar o máximo partido da sua estada, ampliando a intensidade da visita e a amplitude dos seus movimentos. No contexto urbano, os turistas geralmente incluem várias atrações nos seus itinerários intra-destination, o que faz da cidade o palco por excelência da visita multi-attraction. No entanto, são ainda relativamente poucos os estudos empíricos nesta área, em especial no contexto intra-destination. Assim, para além de procurar aprofundar a investigação neste domínio, a presente pesquisa tem como aspeto inovador testar este impacte da duração da estada sobre o comportamento espácio-temporal do turista entendido no seu âmbito global, combinando as suas duas dimensões – ‘movimento’ e ‘multi-attraction’. Com base nos dados recolhidos por inquérito e estudo de rastreamento GPS (Global Positioning System) junto de turistas hospedados em dez diferentes hotéis na cidade de Lisboa (n=408), foi possível identificar diferenças estatisticamente significativas com base na duração da estada, confirmando a importância deste impacte sobre o comportamento espácio-temporal dos turistas.

Creators: name: Tranchita, Anthony Phillip
Publisher: name: Utah State University
Year: 2002

description: Alcohol misuse is a very common problem with high financial and personal costs. Treatment requires allocation of limited resources for optimal impact. Responsible decision making in this area should be based upon reasoned weighing of research evidence. Miller and colleagues completed a meta-analytic review of all controlled studies published before 1992 to help clinicians do just that. The coding system they employed examined methodological quality, as well as outcome, to obtain a rank­ordering of treatments that seem to have the most quality research support. The current study attempts to extend this work utilizing the same coding on studies published since 1992, and combine both databases of articles. Revised rank orderings of treatments and conclusions regarding variables related to outcomes are reported. Implications are discussed, along with limitations of this review. An upward trend in methodological quality over time was also discovered.

description: The magnetic structures which endow TbMnO$_3$ with its multiferroic properties have been reassessed on the basis of a comprehensive soft x-ray resonant scattering (XRS) study. The selectivity of XRS facilitated separation of the various contributions (Mn $L_2$ edge, Mn 3d moments; Tb M$_4$ edge, Tb 4f moments), while its variation with azimuth provided information on the moment direction of distinct Fourier components. When the data are combined with a detailed group theory analysis, a new picture emerges of the ferroelectric transition at 28 K. Instead of being driven by the transition from a collinear to a non-collinear magnetic structure, as has previously been supposed, it is shown to occur between two non-collinear structures.

Using experimental data and simulations, we show that the ICTA has near-quantum-limited noise as long as the integral voltage bias noise divided by the superconducting flux quantum is below the amplification bandwidth. We observe a gain of 20 dB with noise below 1.7 times the quantum limit when the full width at half maximum of the integral voltage noise, expressed as frequency, is 5.6 MHz.

description: Diffuse intracluster light (ICL) has now been observed in nearby and in intermediate redshift clusters. Individual intracluster stars have been detected in the Virgo and Coma clusters and the first color-magnitude diagram and velocity measurements have been obtained. Recent studies show that the ICL contains of the order of 10% and perhaps up to 30% of the stellar mass in the cluster, but in the cores of some dense and rich clusters like Coma, the local ICL fraction can be high as 40%-50%. What can we learn from the ICL about the formation of galaxy clusters and the evolution of cluster galaxies? How and when did the ICL form? What is the connection to the central brightest cluster galaxy? Cosmological N-body and hydrodynamical simulations are beginning to make predictions for the kinematics and origin of the ICL. The ICL traces the evolution of baryonic substructures in dense environments and can thus be used to constrain some aspects of cosmological simulations that are most uncertain, such as the modeling of star formation and the mass distribution of the baryonic component in galaxies.

description: Thioacetamide (CH3CSNH2) is the sulfur analog to acetamide (CH3CONH2) and it is a viable candidate to search for in astronomical environments specifically toward regions where other S-bearing molecules have been found and, if possible, that also contain a detection of CH3CONH2. If detected, it would not only continue to expand the view of molecular complexity in astronomical environments, but also help to better elucidate the possible formation pathways of these types of species in these environments. The rotational spectrum of CH3CSNH2 was investigated up to 650 GHz. Using the newly refined spectrum of CH3CSNH2, as well as additional spectroscopic data on the chemically related species CH3CONH2, a variety of astronomical sources were searched including data from the following large surveys: The PRIMOS conducted with the Green Bank Telescope (GBT); Exploring molecular complexity with ALMA (EMoCA) conducted with ALMA; and Astrochemical Surveys at IRAM (ASAI) conducted with the Institut de Radioastronomie Millimetrique (IRAM) 30m Telescope. A total of 1428 transitions from the vt=0 state with maximum values J=47 and Ka=20 in the range up to 330 GHz, and J=95 and Ka=20 in the range from 400 - 660 GHz were assigned. We also assigned 321 transitions from the vt=1 state with the maximum values J=35 and Ka=9 up to 330 GHz. The final fit is based on the rho-axis-method (RAM) Hamiltonian model that includes 40 parameters. An astronomical search for CH3CSNH2 was conducted based on all the new spectroscopic data. No transitions of CH3CSNH2 were detected toward any of the sources contained in our survey. Using the appropriate telescope and physical parameters for each astronomical source, upper limits to the column densities were found for CH3CSNH2 toward each source.

title: Production of Mountain Whitefish (Prosopium williamsoni) in Altered and Unaltered Reaches of Two Intermountain Streams in Their Alluvial Flood Plains
Creators: name: Ottenbacher, Michael J.
Publisher: name: Utah State University
Year: 1980

description: Estimates of production and related parameters (growth rate, density, standing crop) were made for populations of mountain whitefish in altered and "unaltered" areas of the Glacksmith Fork and Logan River, UtJh from spring 1975 through summer 1976. Capture records of marked whitefish were also analyzed to describe fish movement and check on assumptions implicit in the population estimator.
Mean weights and instantaneous growth rates of whitefish were similar at all sites for comparable size/age groups. Among sites, differences in production per sampling interval and annual production were due mainly to differences in standing crop and/or age structure.
Estimates of mountain whitefish density varied by site and season and ranged from 0 to 3,467 fish/ha, with the highest densities occurring during the fall and winter (spawning season) and the lowest during the summer when streamflows were low. Estimates of standing crops of whitefish followed a pattern similar to density. In the sites where fish remained during the summer most production occurred during the spring and summer.
A bulldozed reach of the Logan River (including an "unstable" section) had the highest annual production of mountain whitefish (51.85 kg/ha/yr)--almost double the annual production for the same reach when the unstable section was not included (31.85 kg/ha/yr). The highest annual production of whitefish in sites in the Blacksmith Fork River (51.23 kg/ha/yr) occurred in a reach that had been recently dredged but still contained a riffle and pool structure. Annual production of whitefish was low in a recently bulldozed reach (5.47 kg/ha/yr) and an old bulldozed reach (10.08 kg/ha/yr) of the Blacksmith Fork River where suitable habitat (pools and glides) was lacking, especially during the summer months.
Mountain whitefish remained or returned to reaches after channel alterations as long as water depth remained sufficient.
This study illustrated the necessity of frequent sampling when attempting to evaluate the effects of perturbations on fish populations or in production studies in general.

title: Chlorophyll Fluorescence Probe of Ultraviolet-B Photoinhibition of Primary Photoreactions in Intact Leaves
Creators: name: Nowak, Robert S.
Publisher: name: Utah State University
Year: 1980

description: Damage to primary photosynthetic reactions caused by environmental stress can be assessed by measurement of chlorophyll fluorescence induction in intact leaves. This approach was applied in studies of ultraviolet-B photoinhibition of photosynthesis in Pisum sativum L. and Rumex patientia L. leaves. At ultraviolet-B dose rates insufficient to cause inhibition of net photosynthesis, changes in the magnitude of fluorescence transients did occur, which suggested direct effects on chloroplast pigments in Pisum and inhibition of photosynthetic electron transport between the photosystems in both species. Leaves of these two species subjected to a much higher dose rate had a significant reduction of net photosynthesis and changes in the magnitude of fluorescence transients that indicated partial loss of water-splitting capability and direct effects on chloroplast pigments. Ultraviolet radiation-induced changes of photosynthetic thylakoid membranes may be ultimately responsible for these disruptions of the primary photosynthetic reactions.

description: As regiões insulares enfrentam desafios ambientais crescentes, em parte decorrentes das alterações climáticas em curso. Os impactos das mesmas afiguram-se potencialmente disruptivos ao nível da atividade turística, principal setor económico na generalidade das regiões insulares. Este artigo analisa as atitudes dos turistas relativamente a um conjunto de temas na interseção da temática dos desastres naturais e das alterações climáticas. Embora a Região Autónoma da Madeira (RAM) continue a oferecer índices de satisfação elevados em termos da experiência turística, e tenha recuperado das perdas associadas aos eventos do 20 de fevereiro de 2010, o relevar da gestão atempada de crises não pode ser mais adiado ou menorizado. Os resultados do estudo resultam da análise de um questionário distribuído a uma amostra de cerca de 300 turistas. Embora se constate uma apreciação geral positiva do destino e elevadas taxas declaradas de intenção de retorno ao destino, a importância e dependência do fator “clima ameno” na experiência são bem patentes na seleção do destino. É também patente o reflexo das condições climatéricas mais desfavoráveis na apreciação global da estadia, o que adiciona um elemento probabilístico à gestão do dia a dia por parte dos turistas. Os resultados do estudo sugerem que os operadores devem reforçar os pontos fortes do destino e acomodar as expetativas dos turistas através da gestão das estadias condicionadas por episódios de tempo menos favorável.

description: JADES-GS-z14-0 is the most distant spectroscopically confirmed galaxy yet, at $z>14$. With a UV magnitude of -20.81, it is one of the most luminous galaxies at cosmic dawn and its half-light radius of 260 pc means that stars dominate the observed UV emission. We report ALMA detection of [OIII]88$μ$m line emission with a significance of 6.67$σ$ and at a frequency of 223.524~GHz, corresponding to a redshift of $14.1796\pm0.0007$, which is consistent with the candidate CIII] line detected in the NIRSpec spectrum. At this spectroscopic redshift, the Lyman-$α$ break identified with NIRSpec requires a damped Lyman-$α$ absorber with a column density of $\log(N_{\rm HI}/\mathrm{cm}^{-2})=21.96$. The total [O\,{\sc iii}]88$μ$m luminosity (log$(L_{\rm [OIII]}/L_\odot) = 8.3\pm 0.1$) is fully consistent with the local $L_{\rm [OIII]}-SFR$ relation and indicating a gas-phase metallicity $>0.1~{\rm Z_{\rm \odot}}$. Using \texttt{prospector} SED modeling and combining the ALMA data with JWST observations, we find $Z=0.17~{\rm Z_{\rm \odot}}$ and a non-zero escape fraction of ionizing photons ($\sim11\%$), which is necessary by the code to reproduce the UV spectrum. We measure an ${\rm [O III]}5007$Å/[O III]88$μ$m line flux ratio between 1 and 20, resulting in an upper limit to the electron density of roughly 700 cm$^{-3}$ assuming a single-cloud photoionization model. The [OIIII]88$μ$m emission line is spectrally resolved, with a FWHM of 100 km/s, resulting in a dynamical mass of log($M_{\rm dyn}/M_\odot$) = 9.0$\pm0.2$. When compared to the stellar mass, this value represents a conservative upper limit on the gas mass fraction, which ranges from 50\% to 80\%, depending on the assumed star formation history. Past radiation-driven outflows may have cleared the galaxy from the gas, reducing the gas fraction and thus increasing the escape fraction of ionizing photons.

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: O presente estudo tem como objetivo estudar a modalidade do autocaravanismo em Portugal. Este é uma modalidade de turismo que, apesar de estar em expansão em vários países europeus, é pouco valorizado pelas entidades públicas e privadas do setor do turismo em Portugal e, do ponto de vista da investigação científica, constitui um tópico também pouco explorado. O sucesso da oferta turística em atrair e fidelizar turistas depende do seu posicionamento face às necessidades e desejos do mercado-alvo. Pretende-se assim aprofundar o conhecimento do perfil dos praticantes de autocaravanismo e fornecer um contributo para futuras ações estratégicas de promoção e acolhimento ao autocaravanismo. Para concretizar este objetivo foi aplicado um inquérito a uma amostra de 271 autocaravanistas portugueses, que constitui a base empírica deste estudo. Os resultados obtidos permitiram compreender a importância atribuída a diferentes fatores no processo de decisão associado ao destino e a identificação de motivações subjacentes ao autocaravanismo, bem como analisar o comportamento dos autocaravanistas em relação a práticas no destino. Os resultados mostram a relevância que estes fatores poderão ter em futuras políticas de desenvolvimento desta modalidade, suportadas na sustentabilidade e competitividade dos destinos.

description: An example of a cold massive core, JCMT 18354-0649S, a possible high mass analogue to a low mass star forming core is studied. Line and continuum observations from JCMT, Mopra Telescope and Spitzer are presented and modelled in detail using a 3D molecular line radiative transfer code. In almost every way JCMT 18354-0649S is a scaled-up version of a typical low mass core with similar temperatures, chemical abundances and densities. The difference is that both the infall velocity and the turbulent width of the line profiles are an order of magnitude larger. While the higher infall velocity is expected due to the large mass of JCMT 18354-0649S, we suggest that the dissipation of this highly supersonic turbulence may lead to the creation of dense clumps of gas that surround the high mass core.
