Résumé :

Based on the analysis of archival material, and combined with ethnographic fieldwork conducted among the Finnish Kaale (the Finnish Romani population) since 2011, this article looks at the historical intertwining of Roma religious and social activism in Finland from the beginning of the 20th century. A focus is placed on the role of the Gypsy Mission (Mustalaislähetys), nowadays Romani Mission (Romano Missio), in shaping both historical and present-day Roma policy, activism and mobilisation within the country. Founded in 1906, and initially led by non-Roma Evangelicals, its impact has nevertheless moved beyond a strictly Roma-focused/non-Roma-led mission. While rarely mentioned, Kaale were active participants within the organisation, and some of the earliest Roma activists were shaped within its midst. Furthermore, Roma mobilisation in the country continues to have a religious undertone, particularly in the contemporary transnational humanitarian work conducted by Finnish Kaale missionaries among Roma communities in Eastern Europe. Tracing the legacy of present-day religious mobilisation among Roma in Finland, as well as Finnish Roma’s active involvement in shaping Roma-projects elsewhere in Europe, is therefore crucial in revealing not only contrasts in how Roma activism may have manifested during the interwar period in Europe (from political to religious, from Roma-led to Roma-focused) but points to the present-day influence of Evangelical missions in shaping particular visions of the ‘future’ among Roma communities across Europe.

Résumé :

The creation of an EU Framework for national Roma integration strategies (2011) marks a significant step in the politicisation of Roma identity by ensuring a further increase in the number of initiatives, projects and programmes explicitly targeting Roma. The Framework itself is part of a process that began with postcommunist transition and which has produced historically unprecedented levels of Roma political activism along with a proliferation of national and transnational policy initiatives focussed on Roma identity. In seeking to explain this contemporary political phenomenon, the article argues that Roma is an identity constructed at the intersection of political and expert knowledge by various actors, such as policymakers, Romani activists, international organizations and scholars. This political-expert identity is applied to groups that are not bounded by a common language, religion, cultural practice, geographic location, occupation, physical appearance or lifestyle. The article explores how this collation of disparate populations into a notional political community builds upon a centuries-old Gypsy legacy. It scrutinizes five strands of identification practices that have contributed to the longue durée development of today’s Roma as an epistemic object and policy target: police profiling of particular communities; administrative surveys; Romani activism; Roma targeted policies; quantitative scientific research. The article argues that the contemporary economic and political conditions amidst which the politicisation of Roma identity is occurring explain how the ideological and institutional construction of the ethnic frame tends toward the reinforcement of the exclusion of those categorised as Roma, thus increasing the perceived need for Roma policy initiatives. A self-sustaining cycle has been created where Roma knowledge identifies Roma problems requiring a policy response, which produces more Roma knowledge, more needs and more policy responses. Yet, there are consequences to racialising public discourse by presenting Roma as both problematic and essentially different from everyone else. Hostility towards Roma has increased in many states indicating that the expert framing of Roma groupness affects social solidarity by disconnecting and distancing Roma from their fellow citizens.

Résumé :

The editorial introduces the key ideas of this thematic issue, which originated within the European Research Council project ‘RomaInterbellum. Roma Civic Emancipation between the Two World Wars.’ The period between WWI and WWII in the region of Central, Southeastern and Eastern Europe was an era of worldwide significant changes, which marked the birth of the Roma civic emancipation movement and impacted Roma communities’ living strategies and visions about their future, worldwide. The aspiration of this thematic issue is to present the main dimensions of the processes of Roma civic emancipation and to outline the role of the Roma as active participants in the historical processes occurring in the studied region and as the creators of their own history. The editorial offers clarifications on the terminology and methodology employed in the articles included in this issue and their spatial and chronological parameters while also briefly introducing the individual authored studies of this issue.

Résumé :

<p>From the beginning, academic research on Gypsies in Western Europe has presented their nomadic way of life as their most important and essential feature, a key pillar of their community identity. Measures for their sedentarisation were perceived as a shackle in a chain of persecutions, and the policy of sedentarisation conducted in the 1950s–1970s in Central, South-Eastern, and Eastern Europe has continuously been interpreted as an example of the crimes of the communist regimes against the human and cultural rights of Roma. What has been missing, however, in these interpretations is the stance on the issue of nomadism as expressed by the Roma themselves and, more specifically, by the Roma civic elite: namely, by the Roma activists who initiated the Roma civic emancipation and created the first Roma organizations in the regions. In recent years, a need to critically re-think the field of Romani Studies in order to take into account the viewpoint of the studied community comes in the foreground of academic and civil society discussions. Such re-consideration is unavoidable also in studying the field of Roma history. This article strives to fill this knowledge gap and to initiate a new discussion about the issue of the so-called Gypsy nomadism. The viewpoints on this issue, coming from the Roma civic elite itself, are presented primarily on the basis of historical evidence from the interwar period, but are not limited to its framework. Finally, later historical developments in the issue of Roma activists’ approach to Gypsy nomadism will also be outlined, including its contemporary dimensions.</p>

Résumé :

The only Romani newspaper of interwar Yugoslavia, Romano lil/Ciganske novine (the latter meaning ‘Gypsy newspaper’ in Serbian), was published in Belgrade in 1935 comprising only three monthly issues. The most prominent Yugoslav Romani activist of the time, Svetozar Simić, was the editor of the newspaper, giving tribute to his visions of what Roma should do for the prosperity of their own community. In terms of content, the newspaper articles seem to be strategically thought-out with the aim of creating a narrative about the Roma, as people united by common culture and historical memory, equal to the other people of the Yugoslav Kingdom, who needed to be included in all processes of the social and public sphere. This article looks into the essence of some messages that the newspaper conveys regarding Roma’s social inclusion, such as (1) education and professional training as a key for a better future, (2) the need for Roma to be more engaged and to self-organise as a community and (3) the fight against majority misconceptions about the Gypsies. The article presents and analyses these three elements of Svetozar Simić’s visions for Romani social inclusion as presented in his editorial pieces. The analysis also pays attention to the resemblances between some of the main messages of the Romani activism in the interwar period and the activism for Roma inclusion in later periods, including parallels during the time of Yugoslav Socialism and the period of democratic transition up until today.

Résumé :

Stereotypical perceptions of Roma people as those who like to walk along forest paths to camps, or stories about Gypsy fairies with crystal balls have nothing in common with such trendy and contemporary terms as new technologies. How can one imagine a stereotypical Roma who loves horses and campfires surfing the Internet? How do we discuss changes in men-women relations in the context of a patriarchal community in which women have no right to express their opinions and are literally captive? Undoubtedly, a lack of knowledge about Roma people, and with often the only alternative in the form of stereotypical information excludes them from the discussion on cultural changes related to technological development. At the same time media, including the Internet, are important not only in the context of activism of Roma leaders and organizations, but also with reference to people who want to fight against the negative image of Roma people in public space, regardless of membership or lack of membership in Roma organizations.

Résumé :

In the mid-19th century, European nations consolidated their identities. Leaders de.ned who belonged to the nation and who did not—excluding both ethnic and ideological Others, such as the Roma (“Gypsies”) and nonconforming artists who were identified with the Roma and dubbed “Bohemians.” Understanding how “Bohemians” were dealt with illuminates not only the avantgarde but strategies used to police cultural activism for the last century and a half.

Résumé :

Language and discourse are basic tools in political mobilization, interaction, negotiation, and legitimization. This article discusses discourse as a form of social action in the processes of politicization of Romani ethnogenesis and in the construction of Romani nationhood. The main research questions focus on the political language that the International Romani Movement (IRM) has been seeking to forge (mainly in the last two decades), on the alternative frames it can provide, and its unifying potential, serving as the basis for collective national identity. This new political discourse is viewed as performing several functions: creating a sense of homogeneity, devising strategies for interaction and self-reflexivity, providing collective coping mechanisms against internal divisions or external threats, and aiming at positive representation through normative transformation. Answers are sought to questions regarding how old and new values, meanings and traditions should be embodied in the language of Romani ethnonationalism, or when dealing with taboo and sensitive issues. A multiperspectival framework has been applied to analyse interviews, field data, and selected texts from Roma policy documents, media publications, and public speeches. Conclusions have been made regarding the choice of power relations Roma resolve to engage in and the contextual factors for achieving legitimacy.

Résumé :

This article is a comparative analysis of state-socialist policies towards the East European Gypsies (Roma). I make two related arguments. First, the Gypsy policies of East European states evolved differently and resulted in considerable variation. Second, notwithstanding the state-socialist social control policies, a measure of independent Romani activism did emerge laying the groundwork for post-socialist Gypsy mobilization.

Résumé :

Il focus di questa ricerca è il contesto dell’attivismo rom in Albania, l’assetto familiare che lo contraddistingue e il sistema del mercato dell’aiuto allo sviluppo in cui è inserito. Nella prima parte è ripercorsa la storia della comunità rom nell’area balcanica e in Albania, dalle prime attestazioni in epoca ottomana fino al trentennio socialista in epoca contemporanea. Nella seconda parte la storia della comunità rom in Albania è intrecciata con il resoconto della nascita del movimento rom per la società civile suddiviso in tre fasi storiche caratterizzate da tre diverse generazioni di leader e di protagonisti. Il movimento sarà analizzato delineando le tematiche emerse, soprattutto la sovrapposizione tra i “legami associativi” e i “legami familiari” e l’ indebitamento delle organizzazioni causato dal “sistema dei rimborsi” che regola il funzionamento della progettazione e dunque l’accesso alle risorse economiche.
The focus of this research is the context of Roma activism in Albania, the family structure that distinguishes it and the system of the development aid market in which it is embedded. In the first part, the history of the Roma community in the Balkans and in Albania is traced, from the earliest occurrences in the Ottoman era to the 30-year socialist period in contemporary times. In the second part, the history of the Roma community in Albania is intertwined with an account of the new born Roma movement for civil society divided into three historical phases characterised by three different generations of leaders and protagonists. The movement will be analysed by outlining the issues that emerged, especially the overlap between "associative ties" and " kinship ties" and the indebtedness of the organisations caused by the "reimbursement system" that regulates the functioning of the cycle project management and therefore access to economic resources.

Résumé :

Les cinq premières parties, chronologiques, sont consacrées à une étude critique des textes anciens mentionnant des séditions militaires et à l'élaboration d'un catalogue. Celui-ci permet de constater que sur les 69 épisodes retenus, l'écrasante majorité intervient au cours des guerres civiles, qui ne couvrent pourtant que 15 % de toute la période étudiée, et ce même si l'on ne tient pas compte du phénomène particulier des débauchages de troupes. La sixième partie est un essai de synthèse qui étudie plus particulièrement les doléances et les revendications des soldats, ainsi que leurs rapports avec les autorités. Elle permet de mettre en lumière certains phénomènes caractéristiques. La conscription a provoqué des résistances tout au long de la période étudiée, le service militaire étant en général très impopulaire. Avant l'ère des guerres civiles, les séditions furent cependant rarissimes, et les seules préoccupations véritablement communes aux milites paraissent avoir été liées a la question de la longueur du service et à l'acquisition du butin. Leurs successeurs du Ier siècle bénéficièrent de moyens de pression importants sur leurs généraux et d'un relâchement de la discipline, ce qui leur permit d'obtenir l'octroi de primes en argent et, à partir de 47, de distributions de terres. Ces revendications émanaient le plus souvent des vétérans qui approchaient du terme du service et qui désiraient monnayer au prix fort leur rengagement volontaire. Il ne s'agissait pas de défendre des intérêts corporatistes mais d'obtenir des avantages strictement personnels. On ne peut parler de politisation des armées que dans la mesure où les milites appuyèrent les chefs qui paraissaient les plus aptes à défendre ces intérêts. Auguste fut le véritable créateur de l'armée professionnelle, en réformant les conditions du service militaire qui étaient devenues nettement moins attrayantes. A sa mort, le mécontentement était grand et il éclata de manière brutale. Les soldats présentèrent un programme précis, qui portait essentiellement sur la réduction de la durée du service et l'augmentation de la solde. Ils n'obtinrent finalement que le renvoi des vétérans les plus âgés.

Résumé :

Abstract: This research paper on Non-Pollen Palynomorph was conducted in Tiber delta (Rome, central Italy). Specifically, sediments from Lingua d'Oca-Interporto (LOI) near Fiumicino airport. By using palynological approach of Non-Pollen Palynomorph the relationship between humans' cultural behavior with the surrounding environment were studied. Thus, the main objectives of the research were to reconstruct the livestock activity of the area by focusing coprophilous fungi and also to evaluate the importance of NPP in the understanding of paleoenvironmental reconstruction. In order to have adequate coverage of the lithological phases and to have good coverage of the environments identified by the pollen record, 25 samples were selected for NPPs analysis ca. 10 cm interval along the whole sedimentary sequence. As a result, the sequence from Stagno di Maccarese reveals a total of 1563 Non-Pollen Palynomorphs. A total of 58 taxonomical groups were recognized with the highest number represented by fungal spores, plant fragments, spores of algae and animal remains. Cercophora sp., cf. Endophragmiella, Coniochaeta cf. ligniaria and cf. round charcoal is the most frequent palynomorph in the samples. According to the research, the findings of the study provide new insights to reveal the subsistence selection of prehistoric humans and the history of livestock habitation in the surrounding archaeological sites. In conclusion, the identified NPPs shows the continual presence of animals in the past landscapes, supporting the evidence of pastures and livestock activities in the region. It also recorded the presence and the effect of humans on the landscape of the region with other natural factors.

Résumé :

Os inibidores da enzima acetilcolinesterase constituem o principal tratamento da doença de Alzheimer e fontes de substâncias naturais com potencial anticolinesterásico vêm sendo amplamente estudadas. Dentre os frutos com benefícios para a saúde, a romã é evidenciada como excelente fonte de compostos antioxidantes, sendo que maior parte dos compostos se concentram em sua casca. Com base nisso, o objetivo desta pesquisa foi buscar novas substâncias naturais com potencial anticolinesterásico, através da avaliação de extratos de casca de romã. Quatro extratos com diferentes concentrações de etanol foram analisados quanto à atividade antioxidante, quantidade de compostos fenólicos, taninos e atividade anticolinesterásica. Do presente estudo foi constatado que a casca da romã apresentou elevada capacidade antioxidante, independente da concentração do solvente de extração empregado. O extrato formulado com 80% de etanol se destacou perante os demais pelo seu poder de inibição da acetilcolinesterase. Houve correlação negativa entre a atividade anticolinesterásica e a atividade antioxidante dos extratos. A atomização do extrato não acarretou mudanças em sua atividade anticolinesterásica e nem na sua capacidade antioxidante. Da mesma forma, a adição das micropartículas a um suco elaborado a partir de um preparado em pó não modificou suas características sensoriais. Diante do exposto, a elaboração de micropartículas de extrato de casca de romã constitui alternativa viável para a incorporação em diversos produtos, com a finalidade de prevenir ou reduzir risco da doença de Alzheimer.
The acetylcholinesterase inhibitors are the primary treatment of Alzheimer\'s disease and sources of natural substances with potential anticholinesterase have been widely studied. Among the fruits with health benefits, the pomegranate is evidenced as an excellent source of antioxidant compounds, and most compounds are concentrated in its peel. Based on this, the objective of this research was to find new substances with potential anticholinesterase, through the evaluation of pomegranate peel extracts. Four extracts with different concentrations of ethanol were analyzed for their antioxidant activity, amount of phenolic compounds, tannins and anticholinesterase activity. From this study it was found that pomegranate peel showed high antioxidant capacity, independent of the concentration of the solvent extraction employed. The extract formulated with 80% ethanol in relation to other stood out by his power of acetylcholinesterase inhibition. There was a negative correlation between acetylcholinesterase activity and antioxidant activity of the extracts. Microencapsulation of extract did not cause changes in their anticholinesterase activity and antioxidant capacity. The same way, the addition of microcapsules to a powder preparation for refreshment not changed their sensory characteristics. Given the above, the preparation of microcapsules of pomegranate peel extract is a viable alternative for incorporation into various products, in order to prevent or reduce risk of Alzheimer\'s disease.

Résumé :

This thesis examines the rural settlement, landscape and two rural economic activities: olive oil and amphorae production on the Tarhuna plateau of Tripolitania. This was gendered from the Late Neo-Punic through the Roman period. Tripolitania is considered one of the main olive oil production regions during the Roman imperial era. Previous studies have tended to stress that presses of the Gebel Tarhuna were totally used for olive oil production, but the new evidence identified by the Tarhuna Archaeological Survey (TAS) has addressed that the wine was also produced to some extent in this area during the Roman period. The study has shown that there was a close relationship between olive oil and wine production and amphorae production by identifying new 14 amphora kiln sites with a quite large number of amphora stamps. These stamps reveal that these amphora workshops mostly located within estates belong to the urban elite. The dissertation is divided into six chapters. The first half of the thesis is dealing with the geographic and literary background, the TAS and the ancient rural settlement on the Tarhuna plateau. After this, chapters are devoted to examine pressing facilities and the press element typology. This examination led me to estimate the capacity production of about 200 presses recorded in the Wadis Turgut and Doga with their close relationship to amphora production sites. Finally, some evaluation points are made with attention paid to the importance of future work as a key factor for improvement the knowledge about rural economic and settlement in this hinterland region of Tripolitania.

Résumé :

To what extent is queer anti-identitarian? And how is it experienced by activists at the European level? At queer festivals, activists, artists and participants come together to build new forms of sociability and practice their ideals through anti-binary and inclusive idioms of gender and sexuality. These ideals are moreover channelled through a series of organisational and cultural practices that aim at the emergence of queer as a collective identity. Through the study of festivals in Amsterdam, Berlin, Rome, Copenhagen, and Oslo, Queer Festivals: Challenging Collective Identities in a Transnational Europe thoughtfully analyses the role of activist practices in the building of collective identities for social movement studies as well as the role of festivals as significant repertoires of collective action and sites of identitarian explorations in contemporary Europe.

Résumé :

AbstractRegardless of the good reputation of the Finnish basic education system, Finnish Roma children fall behind the overall average in their performance of academic skills: Roma children face more challenges completing basic education and have more repeated school years. Furthermore, compared to the average, Roma youth apply less for upper secondary education and thus their general level of education remains low. However, looking at Roma education solely through problematic representations only provides a partial picture. In this article, based on two separate sets of fieldwork among Finnish Kaale Roma, we examine how teachers, Roma activists and mediators perceive the educational trajectories of Finnish Roma children and youth. The article seeks to scrutinize Finnish Roma schooling within the framework of the Finnish National Policy on Roma (NRIS). The analysis highlights the multiplicity of voices in the field, discusses the possibilities, and thus problematizes the single-aspect discourse on Roma education. Many countries in Central and Eastern Europe struggle with school and residential segregation, but Finnish Roma face different challenges.

Résumé :

The paper aims to analyze aspects of Roma marginalization, by identifying and assessing the dimensions of social needs within a compact Roma community, located in a marginalized urban area. The effects of the economic crisis and the COVID-19 pandemic increase inequalities regarding the economic and social situation. The major challenge is to reduce the risk of poverty, especially among families with children, people with disabilities and chronic diseases, but also the social exclusion of people at social risk, based on accurate measurements of social phenomena. The community profile indicates the social status of the inhabitants, which provides a picture of the degree of marginalization and social exclusion of Roma. Thus, the study was conducted by constructing a questionnaire as a research tool, which summarizes the results of the activity of information collection and processing, both based on statistical methods and percentage analysis. The problems faced by marginalized Roma communities are low participation in education, early school leaving, difficult transition to tertiary education, lack of adult skills, low skills among vulnerable people in the labor market, low access to services, poor health and housing. Measures for early detection of situations of social risk and intervention lead to positive effects in preventing marginalization and social exclusion.

Résumé :

A 13 years-old-girl was admitted in our Hospital for a large muscle hematoma of left psoas. At age 3 she had a severe tonsillar bleeding following angina. Afterwards she suffered from easy bruisability and recurrent epistaxis. Prothrombin time (PT) was slightly prolonged (14.7 sec, control 12 sec, INR 1.5), while a more marked prolongation in aPTT was noticed (54.7 sec, control 30.3 sec). All clotting factors resulted within the normal range but Factor X. Factor X antigen was 0.95 U/ml (Laurell), whereas Factor X activity was 0.52 U/ml by extrinsic system assay (rabbit brain and lung thromboplastin), 0.06 U/ml by intrinsic system assay (rabbit brain cephalin) and 1.15 U/ml by activation by RW-cephalin. Chromogenic assays (S-2222 and CBS 3139) perfor med after activation with RW gave 1.02 U/ml and 1.00 U/ml, respectively. The patient plasma had no inhibitory activity against Factor X. The parents of the proposita (first cousins) had Factor X antigen levels and RW functional activity around 1.00 U/ ml, whereas Factor X activity tested by extrinsic and intrinsic system assay was about 0.60 U/ml and 0.50 U/ml, respectively. This Factor X variant seems different from the other ones previously described, showing normal antigen levels and RW activation, a severe defect in the intrinsic activation and only a partial defect in the extrinsic activation. In particular the two defects more close to it (Factor X Friuli and Factor X Melbourne), both found in patients with Italian ancestry, were dif ferent because of a very prolonged PT (Factor X Friuli) or a normal PT (Factor X Melbourne).

Résumé :

The main recommendations of the panel report can be summarised under five key headings:  Scotland in the Roman world: Research into Roman Scotland requires an appreciation of the wider frontier and Empire-wide perspectives, and Scottish projects must be integrated into these wider, international debates. The rich data set and chronological control that Scotland has to offer can be used to inform broader understandings of the impact of Rome.  Changing worlds: Roman Scotland’s rich data set should be employed to contribute to wider theoretical perspectives on topics such as identity and ethnicity, and how these changed over time. What was the experience of daily life for the various peoples in Roman Scotland and how did interactions between incomers and local communities develop and change over the period in question, and, indeed, at and after its end?  Frontier Life: Questions still remain regarding the disposition and chronology of forts and forces, as well as the logistics of sustaining and supplying an army of conquest and occupation. Sites must be viewed as part of a wider, interlocking set of landscapes, and the study of movement over land and by sea incorporated within this. The Antonine Wall provides a continuing focus of research which would benefit from more comparison with frontier structures and regimes in other areas.  Multiple landscapes: Roman sites need to be seen in a broader landscape context, ‘looking beyond the fort’ and explored as nested and interlocking landscapes. This will allow exploration of frontier life and the changing worlds of the Roman period. To do justice to this resource requires two elements: o Development-control archaeology should look as standard at the hinterland of forts (up to c.1 km from the ‘core’), as sensitive areas and worthy of evaluation; examples such as Inveresk show the density of activity around such nodes. The interiors of camps should be extensively excavated as standard. o Integrated approaches to military landscapes are required, bringing in where appropriate topographical and aerial survey, LIDAR, geophysics, the use of stray and metal-detected finds, as well as fieldwalking and ultimately, excavation.  The Legacy of Rome: How did the longer term influence of the Romans, and their legacy, influence the formation, nature and organisation of the Pictish and other emergent kingdoms?

Résumé :

Around the world, populists are associated with economically irresponsible and unsustainable policies. In Rodrigo Duterte’s case in Philippines, the action‐oriented dimension is demonstrated through his tough rhetoric and policies against criminal and anti-social activity, particularly the use of illegal drugs. This is described as the new penal populism.

Texte intégral

Résumé :

Channel Island National Park (CHIS), incorporating five islands off the coast of southern California (Anacapa Island, San Miguel Island, Santa Barbara Island, Santa Cruz Island, and Santa Rosa Island), has an outstanding paleontological record. The park has significant fossils dating from the Late Cretaceous to the Holocene, representing organisms of the sea, the land, and the air. Highlights include: the famous pygmy mammoths that inhabited the conjoined northern islands during the late Pleistocene; the best fossil avifauna of any National Park Service (NPS) unit; intertwined paleontological and cultural records extending into the latest Pleistocene, including Arlington Man, the oldest well-dated human known from North America; calichified “fossil forests”; records of Miocene desmostylians and sirenians, unusual sea mammals; abundant Pleistocene mollusks illustrating changes in sea level and ocean temperature; one of the most thoroughly studied records of microfossils in the NPS; and type specimens for 23 fossil taxa. Paleontological research on the islands of CHIS began in the second half of the 19th century. The first discovery of a mammoth specimen was reported in 1873. Research can be divided into four periods: 1) the few early reports from the 19th century; 2) a sustained burst of activity in the 1920s and 1930s; 3) a second burst from the 1950s into the 1970s; and 4) the modern period of activity, symbolically opened with the 1994 discovery of a nearly complete pygmy mammoth skeleton on Santa Rosa Island. The work associated with this paleontological resource inventory may be considered the beginning of a fifth period. Fossils were specifically mentioned in the 1938 proclamation establishing what was then Channel Islands National Monument, making CHIS one of 18 NPS areas for which paleontological resources are referenced in the enabling legislation. Each of the five islands of CHIS has distinct paleontological and geological records, each has some kind of fossil resources, and almost all of the sedimentary formations on the islands are fossiliferous within CHIS. Anacapa Island and Santa Barbara Island, the two smallest islands, are primarily composed of Miocene volcanic rocks interfingered with small quantities of sedimentary rock and covered with a veneer of Quaternary sediments. Santa Barbara stands apart from Anacapa because it was never part of Santarosae, the landmass that existed at times in the Pleistocene when sea level was low enough that the four northern islands were connected. San Miguel Island, Santa Cruz Island, and Santa Rosa Island have more complex geologic histories. Of these three islands, San Miguel Island has relatively simple geologic structure and few formations. Santa Cruz Island has the most varied geology of the islands, as well as the longest rock record exposed at the surface, beginning with Jurassic metamorphic and intrusive igneous rocks. The Channel Islands have been uplifted and faulted in a complex 20-million-year-long geologic episode tied to the collision of the North American and Pacific Places, the initiation of the San Andreas fault system, and the 90° clockwise rotation of the Transverse Ranges, of which the northern Channel Islands are the westernmost part. Widespread volcanic activity from about 19 to 14 million years ago is evidenced by the igneous rocks found on each island.

Texte intégral

Résumé :

The objective of this research project was to evaluate the involvement of antioxidant enzymes and genes in the resistance mechanism to postharvest superficial scald development using two primary systems: 1. Resistant and susceptible progenies of an apple cross between a scald resistant crab apple, ‘White Angel’ and a scald susceptible cultivar, ‘Rome Beauty’; 2. Heat-treatment of ‘Granny Smith’, which is known to reduce scald development in this cultivar. In 2002 we asked for, and received (October 14), permission to revise our initial objectives. The US side decided to expand their results to include further work using commercial cultivars. Also, both sides wanted to include an emphasis on the interaction between these antioxidant enzymes and the á-farnesene pathway, with the cooperation of a third party, Dr. Bruce Whitaker, USDA-ARS, Beltsville. Background: Superficial scald is a physiological storage disorder that causes damage to the skin of apple and pear fruit. It is currently controlled by use of an antioxidant, diphenylamine (DPA), applied postharvest by drenching or dips, but concern exists about such chemical usage especially as it also involves application of fungicides. As a result, there has been increased emphasis on understanding of the underlying mechanisms involved in disorder development. Our approach was to focus on the oxidative processes that occur during scald development, and specifically on using the two model systems described above to determine if the levels of specific antioxidants and/or antioxidant enzyme activities correlated with the presence/absence of scald. It was hoped that information about the role of antioxidant-defense mechanisms would lead to identification of candidate genes for future transgenic manipulation. Major conclusions, solutions, achievements: Collectively, our results highlight the complexity of superficial scald developmental processes. Studies involving comparisons of antioxidant enzyme activities in different crab apple selection, commercial cultivars, and in response to postharvest heat and 1-methylcyclopropene (1-MCP) treatments, show no simple direct relationships with antioxidant contents and susceptibility of fruit to scald development. However, a correlative relationship was found between POX activity or isoenzyme number and scald resistance in most of the studies. This relationship, if confirmed, could be exploited in breeding for scald resistance. In addition, our investigations with key genes in the á-farnesenebiosynthetic pathway, together with antioxidant processes, are being followed up by analysis of exposed and shaded sides of fruit of cultivars that show different degrees of scald control by 1-MCP. These data may further reveal productive areas for future research that will lead to long term control of the disorder. However, given the complexity of scald development, the greatest research need is the production of transgenic fruit with down-regulated genes involved in á- farnesene biosynthesis in order to test the currently popular hypothesis for scald development.
