Age-dependence of cultured pearl grade and colour in the black-lipped pearl oyster Pinctada margaritifera

Pinctada margaritifera is an economically important marine bivalve species for cultured pearl production in French Polynesian aquaculture. In order to evaluate the influence of donor oyster age on pearl quality traits, experiments were conducted over 6 years using both grafts and surgreffe operations. At harvest, 6 pearl quality traits were recorded and compared: surface defects, luster, grade, darkness level, and visual color. Analyzing the quality traits of pearls harvested in the initial graft process and those of pearls obtained from surgreffe experiments allowed a comparison of the influence of pearl sac cells originating from the initial mantle graft, which aged together with their recipient oysters. The results demonstrated a significant decrease between these successive grafts in luster, grade (A-B-C,) darkness level, and green color – traits that are of major importance in the pearl market. The duplicated graft experiment allowed the comparison of donor oyster families at 2 and 5 years old, where a mantle graft was inserted into recipient oysters aged 2.5 years old. The results showed the same tendencies to a lesser extent, with 1) an improved pearl grade, predominantly through a most important rate of 0 surface defect category, and 2) a green / grey ratio in favor of the younger donor. A comparison between the graft-surgreffe and the duplicated graft experiments also highlighted: 1) the indirect role played by the younger recipient oysters, which must be optimized for optimal pearl quality realization, and 2) the complex interplay between donor and recipient oysters.

Gene-environment interactions in Autism Spectrum Disorders (ASD)

Spectrum Disorder (ASD), is a heterogeneous neurodevelopmental disorder with na estimated global prevalence rate of 17:10000, and a male to female ratio of 4:1. Patients with ASD presente language and communication difficulties and stereotyped behaviours. Comorbidity with other disorders, such as Intelectual Disability, Fragile-X syndrome (FXS) epilepsy and tuberous sclerosis frequently occurs. ASD presents amultifactorial etiopathology, and genetic factos alone are not suficiente to explain how the syndrome arises, with recente studies establishing ASD heritability at approximately 50%. Pre-, peri- and post-natal exposure to toxic environmental factos has been implicated in the development of ASD. Involvement of epigenetic regulatory mechanisms has been suggested, supported by the occurrence of autistic symptoms in patients with disorders aris ing from epigenetic mutations, such as FXS. A polygenic and epistatic model is a strong hypothesis to explain ASD. The main goal of this project is to identify specific exposure patterns to environmental toxicants in children diagnosed with ASD and integrate the results with genetic and epigenetic data.

News telewizyjny jako akt retoryczny

Artykuł przedstawia news telewizyjny jako akt retoryczny. News telewizyjny rozumiany jest jako relacja o wydarzeniu zbudowana zazwyczaj z zapowiedzi i krótkiego kilkuminutowego materiału filmowego (nazywanego czasem felietonem), będącego rezultatem pracy reporter-skiej, wyemitowana w telewizji, zazwyczaj jako jeden z elementów w strukturze magazynu informacyjnego, ale również jako element bloków programowych telewizji informacyjnych. Newsy telewizyjne funkcjonują w mediach jako jeden z elementów działań strategicznych nadawców medialnych nastawionych na określone cele, w tym cele wizerunkowe, polityczne i ekonomiczne. Newsy powstają jako reakcja na konkretne wydarzenia, zaspokajają potrzebę informacji, ale służą też kreowaniu obrazu świata, skupianiu uwagi na pewnych aspektach rze-czywistości, wartościowaniu jej, przekonywaniu o ważności lub nieważności pewnych zda-rzeń. Pełnią funkcje informacyjne, ale też kreacyjne, wzorcotwórcze, stymulacyjne, wartościu-jące, i w końcu estetyczne. Dla osiągnięcia tych celów są odpowiednio konstruowane, z uwzględnieniem specyfiki i potrzeb odbiorcy oraz ethosu nadawcy. W tym sensie są więc ak-tami „retorycznymi”, a więc zamierzonymi, celowymi, będącymi odpowiedzią na określoną sytuację (uwarunkowane są historycznie, społecznie i politycznie) i adresowanymi do określo-nych odbiorców.

Współczesna debata telewizyjna a konflikt destruktywny

W artykule dowodzi się tezy, że współczesne debaty publiczne, emitowane w telewizji (takie jak emitowany od 2004 roku w TVP2 program Jana Pospieszalskiego „Warto rozmawiać”), są zdarzeniami komunikacyjnymi zasadzonymi na konflikcie destruktywnym, a więc takim, który wg L. Kriesberga, nastawiony jest nie na problem wywołujący frustrację, ale jest manifestacją agresji, a celem sporu staje się nie pokonanie różnic dzielących strony, ale pokonanie oponenta. Wynika to z sytuacji komunikacyjnej debaty telewizyjnej i nastawienia w pierwszej kolejności na zdobycie uwagi, a potem zaspokajanie potrzeb odbiorcy sekundarnego – widza. Podporządkowane są temu takie elementy, jak wybór tematu debaty, jej scenariusz, dobór uczestników, a w dalszej kolejności ich zachowania werbalne i niewerbalne. W rezultacie, w debacie telewizyjnej złamane zostają typowe dla debaty konstruktywnej reguły i strategie, i zastąpione zostają zachowaniami typowymi dla konfliktu destruktywnego, takimi jak: brak otwartości na argumenty drugiej strony, nastawienie na pokonanie antagonisty, niechęć do szukania innych rozwiązań, jak tylko moja wygrana - twoja przegrana, działania nastawione na prowokację i podważanie wiarygodności partnera, przenoszenie ciężaru debaty ze sprawy na osobę, posługiwanie się argumentacją niemerytoryczną, niezgoda na konstruowanie wspólnego stanowiska. Taki wzorzec debaty telewizyjnej, która stała się pośpieszną, bezproduktywną prezentacją rozbieżnych stanowisk, nie prowadzącą do żadnych konkluzji, nastawioną najwyżej na obrażenie rozmówcy i dostarczenie widzowi krótkotrwałych emocji, buduje powszechne przekonania o niemożności dialogu i porozumienia w dyskursie publicznym i dominującym w nim antagonizmie.

Tissue and cell's trafficking: a byproduct of transplant activity's trash. The future is now. A Public Health problem

Transplantation is one of the most beautiful achievements for humanity in the last century and became the last hope to many patients. As other beautiful achievements, it has been used by criminals. The future of transplantation will be focused on tissue and cells transplantation. Trafficking of human beings to organ removal and trafficking of human organs are an early stage of trafficking on tissues and cells comparable with slaves trafficking in the 17th and 18th century. As 400 years ago, the motive for the crime is development, economy and profit. Transplant surgery is the modern “cotton gin” to this new commerce. Poverty exploitation, unprotected people, are always the victims. Even so, there are some differences since then. The paying buyers are the patients themselves and the “cotton” transplanted is not so harmless. Unsafe tissues and cells inappropriately collected and allocated can be so dangerous to the recipient and his family, that the dreamed transplant/implant becomes a nightmare. Beyond the trafficking crime, there is a most dangerous associated crime that is the crime of spreading dangerous infectious diseases.

Caregivers' experiences and coping strategies relating to patient's subjective treatment-related cognitive impairment following Haematopoietic Stem Cell Transplant (HSCT)

The treatments involved in cancers of the blood and bone marrow can be physically and psychologically challenging and be associated with adverse secondary effects, including cognitive impairment. The incidence and severity of treatment-related cognitive impairment varies widely, however it can significantly impact quality of life by interfering with patients’ activities of daily living, relationships and future plans. It can also pose challenges for the patients’ caregivers, an area which has received comparatively less research attention. The aim of this study was to investigate caregivers’ experiences of treatment-related cognitive impairment in patients who have undergone Haematopoietic Stem Cell Transplant (HSCT); how they coped, both practically and emotionally, and what supports they believe could help them. Participants were caregivers to individuals who had undergone HSCT within the past 20 years and who had reported cognitive changes at the HSCT Late Effects Clinic, Beatson West of Scotland Cancer Centre. Five participants completed a single semi-structured interview. The data was then analysed using Interpretative Phenomenological Analysis (IPA). Results of this analysis illustrated four super-ordinate themes: noticing change; managing expectations, managing personal feelings and commitment. Findings from the current study highlighted the importance of caregiver education regarding post HSCT cognitive and behavioural changes and providing caregiver emotional support. Future research should explore the mutual needs of both care recipient and caregiver.

Propagação de Camellia sinensis: efeito do genótipo, estaca, substrato, recipiente e ácido indolbutírico

Tem sido relatado que as estacas de Camellia sinensis possuem baixa capacidade de emitir raízes, motivando assim a realização de estudos básicos para otimização do processo de propagação por estacas. Assim sendo, o presente trabalho objetivou quantificar o potencial rizogênico de diferentes genótipos e o efeito da posição da estaca no ramo e incisão na base, do substrato, tamanho do recipiente e ácido indolbutírico no enraizamento de estacas semi-lenhosas dessa espécie. Para tal, foram coletados ramos dos genótipos IAC 259, F15 e Comum, em Pariquera-Açu-SP, no inverno de 2010. em seguida, preparadas as estacas, contendo uma gema e uma folha, foram mantidas em viveiro com 70% de sombreamento. Estacas da posição basal e mediana dos ramos são as mais adequadas para estaquia devido a menor mortalidade e maior enraizamento. A injúria na base da estaca não afeta a mortalidade e o enraizamento das estacas, porém induz à formação de calo. Também não houve diferenças na mortalidade e no enraizamento das estacas quando as mesmas foram mantidas em recipiente de 50, 90 e 120 cm³. Comparado com vermiculita, areia e casca de arroz carbonizada, o solo foi o melhor substrato para estaquia, que na presença do ferimento, juntamente com o tratamento das estacas com 10 g L-1 de AIB promoveu a maior porcentagem de enraizamento. Todavia, ainda nessa condição a mortalidade média das estacas foi de 42%. O potencial de enraizamento do genótipo Comum foi superior ao do IAC 259 e F15.

Costa del Sol (Spain), analysis of economic and land changes caused by tourism

Malaga is in southern Spain, in a region called Andalusia. Costa del Sol belongs to the province of Malaga, near the Strait of Gibraltar and near the coast of Africa (about 300 km) and about 2,300 km of Sluptz. The Costa del Sol is next to the Mediterranean Sea and near the Atlantic Ocean. Strong and rapid growth of tourism in the countries of southern Europe and in Poland. Spain currently (2015) is the third largest inbound of international tourism (68 mil.) and the second inbound in tourism revenue. Europe is a major world tourist region. The first recipient of tourism in the world is France. Most tourism takes place between developed countries.

"Policy externalisation" inherent failure : international financial institutions' conditionality in developing countries

Conditionalities – i.e. ‘exchanging finance for policy reform’ in an asymmetrical relationship between the ‘donor’ and the ‘recipient’ – are central mechanisms of the reform programmes of international financial institutions (IFIs). As they are imposed by outside entities, they can also be viewed as ‘policy externalisation’, which is paradoxically a massive intrusion in the shaping of a country’s domestic policies. The resilience of such devices is remarkable, however. Indeed, in the early 1980s, many developing countries were facing balance of payments difficulties and called upon these international financial institutions for financial relief. In exchange for this relief, they devised economic reforms (fiscal, financial, monetary), which were the conditions for their lending. These reforms were not associated with better economic performance, and this led the IFIs to devise in the 1990s different reforms, which this time targeted the functioning of the government and its ‘governance’, economic problems being explained by governments’ characteristics (e.g., rent-seekers). The paper demonstrates the limitations of the device of conditionality, which is a crucial theoretical and policy issue given its stability across time and countries. These limitations stem from: i) the concept of conditionality per se - the mechanism of exchanging finance for reform; ii) the contents of the prescribed reforms given developing countries economic structure (typically commodity-based export structures) and the weakness of the concept of ‘governance’ in view of these countries’ political economies; and iii) the intrinsic linkages between economic and political conditionalities, whose limitations thus retroact on each other, in particular regarding effectiveness and credibility.

Germ Cell Transplantation in Felids: A Potential Approach to Preserving Endangered Species

With the exception of the domestic cat, all members of the family Felidae are considered either endangered or threatened. Although not yet used for this purpose, spermatogonial stem cell (SSC) transplantation has a high potential to preserve the genetic stock of endangered species. However, this technique has not previously been established in felids. Therefore, we developed the necessary procedures to perform syngeneic and xenogeneic SSC transplants (eg, germ cell [GC] depletion in the recipient domestic cats, enrichment and labeling of donor cell suspension, and the transplantation method) in order to investigate the feasibility of the domestic cat as a recipient for the preservation and propagation of male germ plasm from wild felids. In comparison with busulfan treatment, local x-ray fractionated radiation was a more effective approach to depleting endogenous spermatogenesis. The results of both syngeneic and xenogeneic transplants revealed that SSCs were able to successfully colonize and differentiate in the recipient testis, generating elongated spermatids several weeks posttransplantation. Specifically, ocelot spermatozoa were observed in the cat epididymis 13 weeks following transplantation. As donor GCs from domestic cats and ocelots were able to develop and form mature GCs in the recipient environment seminiferous tubules, these findings indicate that the domestic cat is a suitable recipient for SSC transplantation. Moreover, as modern cats descended from a medium-size cat that existed approximately 10 to 11 million years ago, these results strongly suggest that the domestic cat could be potentially used as a recipient for generating and propagating the genome of wild felids.

De lettre intime à lettre ouverte dans Lettres à l’Indigène de Joël Des Rosiers

Dans la première décennie du XXIe siècle, à l’ère des nouvelles technologies de communication électroniques, le courriel est devenu le moyen par excellence pour envoyer et recevoir du contenu privé, remplaçant dès lors l’envoi de lettres papier. Dans ce contexte, pour quelles raisons un individu souhaiterait-il partager ce contenu privé en le publiant ouvertement, publiquement, de plus, dans un format papier, le rendant désormais disponible à l’ensemble des lecteurs désirant en consulter le contenu? Pourtant, telle est la genèse du recueil Lettres à l’Indigène de Joël Des Rosiers dans lequel l’auteur fait don de lettres d’amour qui « deviennent alors des objets communs que partagent la destinataire et l’homme qui lui écrit, le livre et le lecteur » (LALI, p. 7). Ainsi, c’est par la réappropriation d’une pratique épistolaire ancienne que cet ouvrage rend compte d’une écriture intimiste dans laquelle lettres intimes et lettres ouvertes se côtoient. Les lettres intimes comportent plusieurs ressemblances avec les lettres conventionnelles, mais s’en distinguent sur certains points. Les lettres ouvertes, quant à elles, s’apparentent davantage aux publications libres que l’on retrouve dans les divers périodiques papier ou Web, ainsi que dans les divers blogues. Dans les deux types de lettres, nous voyons quelle est la place du destinateur et celle de l’Autre, nous présentons les différentes constructions de l’espace liées à chacune des formes de lettre et nous dévoilons les diverses stratégies formelles qui laissent voir un jeu entre les sphères publique et privée. Nous démontrons ainsi de quelles manières ce recueil questionne l’intimisme du XXIe siècle, ainsi que la pratique d’une écriture intimiste dans le cadre actuel.

THE CELEBRITY BURDEN: CELEBRITY CAMPAIGNS IN THE PURSUIT OF HUMANITARIANISM

Celebrity participation in humanitarianism and politics has received a lot of attention in recent times. Though many researchers have sought to explain the reasons underlying this phenomenon, there appears to be little information as to the efficacy of these celebrity efforts. The present research thus undertakes an analysis of the celebrity's participation through a study on the effectiveness of the celebrity-led campaign. To achieve this, I conduct a discourse and visual analysis of media publications surrounding two celebrity-led campaigns. The research leans heavy on theories underlining the celebrity mechanism and Street et al's framework on celebrity participation in politics. The study confirms Street et al's argument that performance, legitimacy and organization are central to the success of the celebrity-led campaign. For campaigns aimed at initiating policy change, I propose an additional category of stakeholders' response which provides a means of evaluating efficacy. My findings show that organization, legitimization, stakeholders' response and performance are highly dependent on the actions of the lead celebrity, making these celebrities active agents in the production of discourse on the "third world". As celebrities engage in humanitarian work, they take up positions as representatives of the aid recipient. The result is the dispossession and silencing of the aid recipient. Out of my discussion of these practices evolves the concept of the celebrity burden.

The importance of marine subsidies for terrestrial consumers in coastal Peru

The Peruvian coast is one the best examples of cross-ecosystem food web exchanges, in which resources from one of the richest marine ecosystems subsidize consumers in one of the driest deserts on Earth. Marine subsidies are resources that originate in the marine ecosystem, and that contribute to increase the density of consumers in the recipient ecosystem. I examined the effects of marine subsidies on animal populations in the Peruvian coastal desert. I combined several approaches to study the linkages between marine resources and terrestrial consumers, such as surveying the spatial distribution and estimating the relative abundance of terrestrial consumers, studying the diet of geckos and lizards through stomach content analyses, and examining the desert food web with carbon and nitrogen stable isotope analyses. I found that the distribution and diet of desert consumers were tightly coupled to the availability of marine subsidies. I revealed linkages along two pathways of nutrient fluxes: tidal action that washes ashore macroalgae and cadavers of marine organisms, and animal transport in places where pinnipeds and seabirds congregate for reproduction. In the first pathway, intertidal algivivores made marine resources available to terrestrial consumers by moving between the intertidal and supratidal zone. The relative contribution of terrestrial and algal carbon sources varied among terrestrial consumers, because scorpions assimilated a lower proportion of energy from macroalgae than did geckos and solifuges. In the second pathway, I found that pinniped colonies influenced the diet of desert consumers, and contributed to support large populations of lizards and geckos. By combining field observations, and stomach and stable isotope analyses, I constructed a simplified food web for a large sea lion colony, showing the number of trophic levels that originate from pinniped-derived nutrients. My study demonstrates the enormous importance of marine resources for the diet of desert consumers. The near absence of rainfall along the Peruvian coast promotes an extreme dependence of terrestrial consumers on marine resources, and causes permanent food web effects that are affected by temporal variability in marine productivity, rather then temporal patterns of desert plant growth.
