Proposta di sottotitolaggio del social movie italy in a day

The aim of this thesis is to analyse the main translating issues related to the subtitling of the Italian social movie Italy in a day into English: Italy in a day is a crowdsourced film, comprising a selection of video clips sent by ordinary people, showing occurrences of everyday life on a single day, October 26th, 2013. My dissertation consists of four chapters. The first provides a general overview of audiovisual translation, from the description of the characteristics of filmic products to a summary of the most important audiovisual translation modes; a theoretical framework of the discipline is also provided, through the analysis of the major contributions of Translations Studies and the multidisciplinary approach proposed by the scholar Frederic Chaume. The second chapter offers insight into the subtitling practice, examining its technical parameters, the spatial and temporal constraints, together with the advantages and pitfalls of this translation mode. The main criteria for quality assessment are also outlined, as well as the procedures carried out in the creation of subtitles within a professional environment, with a particular focus on the production of subtitles for the DVD industry. In the third chapter a definition of social movie is provided and the audiovisual material is accurately described, both in form and content. The creation of the subtitling project is here illustrated: after giving some information about the software employed, every step of the process is explained. In the final chapter the main translation challenges are highlighted. In the first part some text reduction techniques in the shift from oral to written are presented; then the culture-specific references and the linguistic variation in the film are analysed and the compensating strategies adopted to fill the linguistic and cultural gap are commented on and justified taking into account the needs and expectations of the target audience.

Is hatchery stocking a help or harm? Evidence, limitations and future directions in ecological and genetic surveys

Hatchery fish stocking for stock enhancement has been operated at a massive and global scale. However, the use of hatchery fish as a means of stock enhancement is highly controversial, and little is known about its effects on wild stock and consequences for stock enhancement. Here we review the scientific literature on this subject in order to address a fundamental - question is hatchery stocking a help or harm for wild stock and stock enhancement? We summarized 266 peer-reviewed papers that were published in the last 50 years, which describe empirical case studies on ecology and genetics of hatchery stocks and their effects on stock enhancement. Specifically, we asked whether hatchery stock and wild stock differed in fitness and the level of genetic variation, and whether stocking affected population abundance. Seventy studies contained comparisons between hatchery and wild stocks, out of which 23 studies showed significantly negative effects of hatchery rearing on the fitness of stocked fish, and 28 studies showed reduced genetic variation in hatchery populations. None of these studies suggested a positive genetic effect on the fitness of hatchery-reared individuals after release. These results suggest that negative effects of hatchery rearing are not just a concern but undeniably present in many aquaculture species. In a few cases, however, no obvious effect of hatchery rearing was observed, and a positive contribution of hatchery stock to the abundance of fish populations was indicated. These examples suggest that there is a chance to improve hatchery practices and mitigate the negative effects on wild stocks, although scientific data supporting the positive effect on stock enhancement are largely missing at this moment. Technically, microsatellite-based parentage assignments have been proven as a useful tool for the evaluation of reproductive fitness in natural settings, which is a key for stock enhancement by hatchery-based stocking. We discuss implications of these results, as well as their limitations and future directions. (C) 2010 Elsevier B.V. All rights reserved.

Lunar tractive forces and renal stone incidence

Background. Several factors are implicated in renal stone formation and peak incidence of renal colic admissions to emergency departments (ED). Little is known about the influence of potential environmental triggers such as lunar gravitational forces. We conducted a retrospective study to test the hypothesis that the incidence of symptomatic renal colics increases at the time of the full and new moon because of increased lunar gravitational forces. Methods. We analysed 1500 patients who attended our ED between 2000 and 2010 because of nephrolithiasis-induced renal colic. The lunar phases were defined as full moon ± 1 day, new moon ± 1 day, and the days in-between as "normal" days. Results. During this 11-year period, 156 cases of acute nephrolithiasis were diagnosed at the time of a full moon and 146 at the time of a new moon (mean of 0.4 per day for both). 1198 cases were diagnosed on "normal" days (mean 0.4 per day). The incidence of nephrolithiasis in peak and other lunar gravitational phases, the circannual variation and the gender-specific analysis showed no statistically significant differences. Conclusion. In this adequate powered longitudinal study, changes in tractive force during the different lunar phases did not influence the incidence of renal colic admissions in emergency department.

Plant volatiles: production, function and pharmacology

Plant volatiles typically occur as a complex mixture of low-molecular weight lipophilic compounds derived from different biosynthetic pathways, and are seemingly produced as part of a defense strategy against biotic and abiotic stress, as well as contributing to various physiological functions of the producer organism. The biochemistry and molecular biology of plant volatiles is complex, and involves the interplay of several biochemical pathways and hundreds of genes. All plants are able to store and emit volatile organic compounds (VOCs), but the process shows remarkable genotypic variation and phenotypic plasticity. From a physiological standpoint, plant volatiles are involved in three critical processes, namely plant–plant interaction, the signaling between symbiotic organisms, and the attraction of pollinating insects. Their role in these ‘‘housekeeping’’ activities underlies agricultural applications that range from the search for sustainable methods for pest control to the production of flavors and fragrances. On the other hand, there is also growing evidence that VOCs are endowed with a range of biological activities in mammals, and that they represent a substantially under-exploited and still largely untapped source of novel drugs and drug leads. This review summarizes recent major developments in the study of biosynthesis, ecological functions and medicinal applications of plant VOCs.

Structural and procedural properties important in promoting bio-enterprises as alternative livelihoods to pastoral and agro-pastoral livelihoods

Alternative livelihoods to pastoral and agro-pastoral livelihoods are increasingly gaining attention in rural development but few empirical evidence exist on how to go about supporting such initiatives. As pastoral and agro-pastoral production conditions change due to various factors including market conditions, climate variability and change, pastoralists and agro-pastoralists are increasingly faced with the challenge of finding alternative livelihoods. Bio-enterprises offer such alternatives or complementary activities for rural actors to adapt to changing socio-ecological conditions. This study examines the roles of bio-enterprise initiatives from a livelihood perspective and identifies the features important for such initiatives to reduce poverty and improve the adaptive capacities of pastoralists and agro-pastoralists. It draws on four different bio-enterprise initiatives on agro-pastoral and pastoral livelihoods and on improved natural resources management (NRM) in the drylands of Kenya. Data were collected through interviews, focus group discussions, informal discussions and the study of reports. Results shows among other factors that diversification into enterprises requires cooperation among the stakeholders with their varying experiences in development, NRM and business development. Other factors such as sustained financial support, capacity development to survive the market introduction phase, as well as quantity and quality of the product, are critical. Mentoring proved to be a driver of success in some initiatives.

Caenorhabditis elegans Heterochromatin protein 1 (HPL-2) links developmental plasticity, longevity and lipid metabolism

Background Heterochromatin protein 1 (HP1) family proteins have a well-characterized role in heterochromatin packaging and gene regulation. Their function in organismal development, however, is less well understood. Here we used genome-wide expression profiling to assess novel functions of the Caenorhabditis elegans HP1 homolog HPL-2 at specific developmental stages. Results We show that HPL-2 regulates the expression of germline genes, extracellular matrix components and genes involved in lipid metabolism. Comparison of our expression data with HPL-2 ChIP-on-chip profiles reveals that a significant number of genes up- and down-regulated in the absence of HPL-2 are bound by HPL-2. Germline genes are specifically up-regulated in hpl-2 mutants, consistent with the function of HPL-2 as a repressor of ectopic germ cell fate. In addition, microarray results and phenotypic analysis suggest that HPL-2 regulates the dauer developmental decision, a striking example of phenotypic plasticity in which environmental conditions determine developmental fate. HPL-2 acts in dauer at least partly through modulation of daf-2/IIS and TGF-β signaling pathways, major determinants of the dauer program. hpl-2 mutants also show increased longevity and altered lipid metabolism, hallmarks of the long-lived, stress resistant dauers. Conclusions Our results suggest that the worm HP1 homologue HPL-2 may coordinately regulate dauer diapause, longevity and lipid metabolism, three processes dependent on developmental input and environmental conditions. Our findings are of general interest as a paradigm of how chromatin factors can both stabilize development by buffering environmental variation, and guide the organism through remodeling events that require plasticity of cell fate regulation.

Caprine PRNP polymorphisms at codons 171, 211, 222 and 240 in a Greek herd and their association with classical scrapie

The association between PRNP variation and scrapie incidence was investigated in a highly affected Greek goat herd. Four mutations were identified at codons 171Q/R, 211R/Q, 222Q/K and 240P/S. Lysine at codon 222 was found to be associated with the protection from natural scrapie (P=0.0111). Glutamine at codon 211 was observed in eight animals, all of them being scrapie-negative, indicating a possible protective role of this polymorphism although statistical analysis failed to support it (P=0.1074). A positive association (P=0.0457) between scrapie-affected goats and the wild-type Q(171)R(211)Q(222)S(240) allele is presented for the first time. In addition, a novel R(171)RQS allele, which is identical to the A(136)R(154)R(171) allele that has been associated with resistance to classical scrapie in sheep, was observed in low frequency. Resistant alleles that include K(222) and Q(211) are absent or rare in sheep and can provide the basis for the development of a feasible breeding programme for scrapie eradication in goats.

Life Events and Interdependent Lives: Implications for Research and Intervention

The central thesis of this article is that a single life event has the capacity to affect and change not one but several lives. This thesis is related to theory on attachment, roles, and convoys. The concept of life-event webs is introduced to capture the complex relations between individuals within networks such as families. Research challenges presented by the life-event web perspective include defining networks, assessing the impact of events on each member, and treating the web, not the individual, as the unit of analysis. The web perspective implies that intervention programs should be focused not on the individual but on the web.

The Constitutional-Judicial Control of the Legislative and Executive Powers in Central and Eastern European Countries

This project looked at the nature, contents, methods, means and legal and political effects of the influence that constitutional courts exercise upon the legislative and executive powers in the newly established democracies of Central and Eastern Europe. The basic hypothesis was that these courts work to provide a limitation of political power within the framework of the principal constitutional values and that they force the legislature and executive to exercise their powers and duties in strict accordance with the constitution. Following a study of the documentary sources, including primarily the relevant constitutional and statutory provisions and decisions of constitutional courts, Mr. Cvetkovski prepared a questionnaire on various aspects of the topics researched and sent it to the respective constitutional courts. A series of direct interviews with court officials in six of the ten countries then served to clarify a large number of questions relating to differences in procedures etc. that arose from the questionnaires. As a final stage, the findings were compared with those described in recent publications on constitutional control in general and in Central and Eastern Europe in particular. The study began by considering the constitutional and political environment of the constitutional courts' activities in controlling legislative and executive powers, which in all countries studied are based on the principles of the rule of law and the separation of powers. All courts are separate bodies with special status in terms of constitutional law and are independent of other political and judicial institutions. The range of matters within their jurisdiction is set by the constitution of the country in question but in all cases can be exercised only with the framework of procedural rules. This gives considerable significance to the question of who sets these rules and different countries have dealt with it in different ways. In some there is a special constitutional law with the same legal force as the constitution itself (Croatia), the majority of countries allow for regulation by an ordinary law, Macedonia gives the court the autonomy to create and change its own rules of procedure, while in Hungary the parliament fixes the rules on procedure at the suggestion of the constitutional court. The question of the appointment of constitutional judges was also considered and of the mechanisms for ensuring their impartiality and immunity. In the area of the courts' scope for providing normative control, considerable differences were found between the different countries. In some cases the courts' jurisdiction is limited to the normative acts of the respective parliaments, and there is generally no provision for challenging unconstitutional omissions by legislation and the executive. There are, however, some situations in which they may indirectly evaluate the constitutionality of legislative omissions, as when the constitution contains provision for a time limit on enacting legislation, when the parliament has made an omission in drafting a law which violates the constitutional provisions, or when a law grants favours to certain groups while excluding others, thereby violating the equal protection clause of the constitution. The control of constitutionality of normative acts can be either preventive or repressive, depending on whether it is implemented before or after the promulgation of the law or other enactment being challenged. In most countries in the region the constitutional courts provide only repressive control, although in Hungary and Poland the courts are competent to perform both preventive and repressive norm control, while in Romania the court's jurisdiction is limited to preventive norm control. Most countries are wary of vesting constitutional courts with preventive norm control because of the danger of their becoming too involved in the day-to-day political debate, but Mr. Cvetkovski points out certain advantages of such control. If combined with a short time limit it can provide early clarification of a constitutional issue, secondly it avoids the problems arising if a law that has been in force for some years is declared to be unconstitutional, and thirdly it may help preserve the prestige of the legislation. Its disadvantages include the difficulty of ascertaining the actual and potential consequences of a norm without the empirical experience of the administration and enforcement of the law, the desirability of a certain distance from the day-to-day arguments surrounding the political process of legislation, the possible effects of changing social and economic conditions, and the danger of placing obstacles in the way of rapid reactions to acute situations. In the case of repressive norm control, this can be either abstract or concrete. The former is initiated by the supreme state organs in order to protect abstract constitutional order and the latter is initiated by ordinary courts, administrative authorities or by individuals. Constitutional courts cannot directly oblige the legislature and executive to pass a new law and this remains a matter of legislative and executive political responsibility. In the case of Poland, the parliament even has the power to dismiss a constitutional court decision by a special majority of votes, which means that the last word lies with the legislature. As the current constitutions of Central and Eastern European countries are newly adopted and differ significantly from the previous ones, the courts' interpretative functions should ensure a degree of unification in the application of the constitution. Some countries (Bulgaria, Hungary, Poland, Slovakia and Russia) provide for the constitutional courts' decisions to have a binding role on the constitutions. While their decisions inevitably have an influence on the actions of public bodies, they do not set criteria for political behaviour, which depends rather on the overall political culture and traditions of the society. All constitutions except that of Belarus, provide for the courts to have jurisdiction over conflicts arising from the distribution of responsibilities between different organs and levels in the country, as well for impeachment procedures against the head of state, and for determining the constitutionality of political parties (except in Belarus, Hungary, Russia and Slovakia). All the constitutions studied guarantee individual rights and freedoms and most courts have jurisdiction over complaints of violation of these rights by the constitution. All courts also have some jurisdiction over international agreements and treaties, either directly (Belarus, Bulgaria and Hungary) before the treaty is ratified, or indirectly (Croatia, Czech Republic, Macedonia, Romania, Russia and Yugoslavia). In each country the question of who may initiate proceedings of norm control is of central importance and is usually regulated by the constitution itself. There are three main possibilities: statutory organs, normal courts and private individuals and the limitations on each of these is discussed in the report. Most courts are limited in their rights to institute ex officio a full-scale review of a point of law, and such rights as they do have rarely been used. In most countries courts' decisions do not have any binding force but must be approved by parliament or impose on parliament the obligation to bring the relevant law into conformity within a certain period. As a result, the courts' position is generally weaker than in other countries in Europe, with parliament remaining the supreme body. In the case of preventive norm control a finding of unconstitutionality may act to suspend the law and or to refer it back to the legislature, where in countries such as Romania it may even be overturned by a two-thirds majority. In repressive norm control a finding of unconstitutionality generally serves to take the relevant law out of legal force from the day of publication of the decision or from another date fixed by the court. If the law is annulled retrospectively this may or may not bring decisions of criminal courts under review, depending on the provisions laid down in the relevant constitution. In cases relating to conflicts of competencies the courts' decisions tend to be declaratory and so have a binding effect inter partes. In the case of a review of an individual act, decisions generally become effective primarily inter partes but is the individual act has been based on an unconstitutional generally binding normative act of the legislature or executive, the findings has quasi-legal effect as it automatically initiates special proceedings in which the law or other regulation is to be annulled or abrogated with effect erga omnes. This wards off further application of the law and thus further violations of individual constitutional rights, but also discourages further constitutional complaints against the same law. Thus the success of one individual's complaint extends to everyone else whose rights have equally been or might have been violated by the respective law. As the body whose act is repealed is obliged to adopt another act and in doing so is bound by the legal position of the constitutional court on the violation of constitutionally guaranteed freedoms and rights of the complainant, in this situation the decision of the constitutional court has the force of a precedent.

A novel SCN5A mutation, F1344S, identified in a patient with Brugada syndrome and fever-induced ventricular fibrillation

OBJECTIVE: Brugada syndrome (BS) is an inherited electrical cardiac disorder characterized by right bundle branch block pattern and ST segment elevation in leads V1 to V3 on surface electrocardiogram that can potentially lead to malignant ventricular tachycardia and sudden cardiac death. About 20% of patients have mutations in the only so far identified gene, SCN5A, which encodes the alpha-subunit of the human cardiac voltage-dependent sodium channel (hNa(v)1.5). Fever has been shown to unmask or trigger the BS phenotype, but the associated molecular and the biophysical mechanisms are still poorly understood. We report on the identification and biophysical characterization of a novel heterozygous missense mutation in SCN5A, F1344S, in a 42-year-old male patient showing the BS phenotype leading to ventricular fibrillation during fever. METHODS: The mutation was reproduced in vitro using site-directed mutagenesis and characterized using the patch clamp technique in the whole-cell configuration. RESULTS: The biophysical characterization of the channels carrying the F1344S mutation revealed a 10 mV mid-point shift of the G/V curve toward more positive voltages during activation. Raising the temperature to 40.5 degrees C further shifted the mid-point activation by 18 mV and significantly changed the slope factor in Na(v)1.5/F1344S mutant channels from -6.49 to -10.27 mV. CONCLUSIONS: Our findings indicate for the first time that the shift in activation and change in the slope factor at a higher temperature mimicking fever could reduce sodium currents' amplitude and trigger the manifestation of the BS phenotype.

The quantitative genetic basis of offspring solicitation and parental response in a passerine bird with biparental care

The coevolution of parental investment and offspring solicitation is driven by partly different evolutionary interests of genes expressed in parents and their offspring. In species with biparental care, the outcome of this conflict ma!: be influenced by the sexual conflict over parental investment, Models for the resolution of such family conflicts have made so far untested assumptions about genetic variation and covariation in the parental resource provisioning response and the level of offspring solicitation. Using a combination of cross-fostering and begging playback experiments, we show that, in the great tit (Parus major), (i) the begging call intensity of nestlings depends on their common origin, suggesting genetic variation for this begging display, (ii) only mothers respond to begging calls by increased food provisioning, and (iii! the size of the parental response is positively related to the begging call intensity of nestlings in the maternal but not paternal line. This study indicates that genetic covariation, its differential expression in the maternal and paternal lines and/or early environmental and parental effects need to be taken into account when predicting the phenotypic outcome of the conflict over investment between genes expressed in each parent and the offspring.

Mast fruiting of large ectomycorrhizal African rain forest trees: importance of dry season intensity, and the resource limitation hypothesis

Mast fruiting is a distinctive reproductive trait in trees. This rain forest study, at a nutrient-poor site with a seasonal climate in tropical Africa, provides new insights into the causes of this mode of phenological patterning. •  At Korup, Cameroon, 150 trees of the large, ectomycorrhizal caesalp, Microberlinia bisulcata, were recorded almost monthly for leafing, flowering and fruiting during 1995–2000. The series was extended to 1988–2004 with less detailed data. Individual transitions in phenology were analysed. •  Masting occurred when the dry season before fruiting was drier, and the one before that was wetter, than average. Intervals between events were usually 2 or 3 yr. Masting was associated with early leaf exchange, followed by mass flowering, and was highly synchronous in the population. Trees at higher elevation showed more fruiting. Output declined between 1995 and 2000. •  Mast fruiting in M. bisulcata appears to be driven by climate variation and is regulated by internal tree processes. The resource-limitation hypothesis was supported. An ‘alternative bearing’ system seems to underlie masting. That ectomycorrhizal habit facilitates masting in trees is strongly implied.

Germline NF1 mutational spectra and loss-of-heterozygosity analyses in patients with pheochromocytoma and neurofibromatosis type 1

BACKGROUND: Neurofibromatosis type 1 (NF1) is a pheochromocytoma-associated syndrome. Because of the low prevalence of pheochromocytoma in NF1, we ascertained subjects by pheochromocytoma that also had NF1 in the hope of describing the germline NF1 mutational spectra of NF1-related pheochromocytoma. MATERIALS AND METHODS: An international registry for NF1-pheochromocytomas was established. Mutation scanning was performed using denaturing HPLC for intragenic variation and quantitative PCR for large deletions. Loss-of-heterozygosity analysis using markers in and around NF1 was performed. RESULTS: There were 37 eligible subjects (ages 14-70 yr). Of 21 patients with corresponding tumor available, 67% showed somatic loss of the nonmutated allele at the NF1 locus vs. 0 of 12 sporadic tumors (P = 0.0002). Overall, 86% of the 37 patients had exonic or splice site mutations, 14% large deletions or duplications; 79% of the mutations are novel. The cysteine-serine rich domain (CSR) was affected in 35% but the RAS GTPase activating protein domain (RGD) in only 13%. There did not appear to be an association between any clinical features, particularly pheochromocytoma presentation and severity, and NF1 mutation genotype. CONCLUSIONS: The germline NF1 mutational spectra comprise intragenic mutations and deletions in individuals with pheochromocytoma and NF1. NF1 mutations tended to cluster in the CSR over the RAS-GAP domain, suggesting that CSR plays a more prominent role in individuals with NF1-pheochromocytoma than in NF1 individuals without this tumor. Loss-of-heterozygosity of NF1 markers in NF1-related pheochromocytoma was significantly more frequent than in sporadic pheochromocytoma, providing further molecular evidence that pheochromocytoma is a true component of NF1.

Gene duplication: a drive for phenotypic diversity and cause of human disease

Gene duplication is one of the key factors driving genetic innovation, i.e., producing novel genetic variants. Although the contribution of whole-genome and segmental duplications to phenotypic diversity across species is widely appreciated, the phenotypic spectrum and potential pathogenicity of small-scale duplications in individual genomes are less well explored. This review discusses the nature of small-scale duplications and the phenotypes produced by such duplications. Phenotypic variation and disease phenotypes induced by duplications are more diverse and widespread than previously anticipated, and duplications are a major class of disease-related genomic variation. Pathogenic duplications particularly involve dosage-sensitive genes with both similar and dissimilar over- and underexpression phenotypes, and genes encoding proteins with a propensity to aggregate. Phenotypes related to human-specific copy number variation in genes regulating environmental responses and immunity are increasingly recognized. Small genomic duplications containing defense-related genes also contribute to complex common phenotypes.
