An assessment of the economic impact of climate change on the tourism sector in Jamaica

Climate change is a continuous process that began centuries ago. Today the pace of change has increased with greater rapidity because of global warming induced by anthropogenically generated greenhouse gases (GHG). Failure to effectively deal with the adverse outcomes can easily disrupt plans for sustainable economic development. Because of the failure of export agriculture over the last several decades, to provide the economic stimuli needed to promote economic growth and development, Jamaica, like many other island states in the Caribbean subregion, has come to rely on tourism as an instrument of transformation of the macro-economy. It is believed this shift in economic imperative would eventually provide the economic impetus needed to generate much needed growth and development. This assessment has shown that tourism is not only a leading earner of foreign exchange in Jamaica and a major creator of both direct and indirect jobs but, also, one of the principal contributors to the country‟s Gross Domestic Product (GDP). The rapid expansion of the industry which occurred over the last several decades coupled with disregard for sound environmental practices has led to the destruction of coral reefs and the silting of wetlands. Because most of the industry is located along the coastal region it is extremely vulnerable to the adverse effects of climate change. Failure to address the predictable environmental challenges of climate change, with some degree of immediacy, will not only undermine, but quickly and seriously impair the capacity of industry to stimulate and contribute to the process of economic development. To this end, it important that further development of industry be characterised by sound economic and social planning and proper environmental practices.

Risk Assessment of the Introduction of H5N1 Highly Pathogenic Avian Influenza as a Tool to be Applied in Prevention Strategy Plan

Risks of the introduction of highly pathogenic avian influenza (HPAI) H5N1 through migratory birds to the main wintering site for wild birds in southern Brazil and its consequences were assessed. Likelihoods were estimated by a qualitative scale ranging from negligible to high. Northern migrants that breed in Alaska and regularly migrate to South America (primary Charadriiformes) can have contact with birds from affected areas in Asia. The likelihood of the introduction of HPAI H5N1 through migratory birds was found to be very low as it is a probability conditioned to successful transmission in breeding areas and the probabilities of an infected bird migrating and shedding the virus as far as southern Brazil. The probability of wild species becoming exposed to H5N1-infected birds is high as they nest with northern migrants from Alaska, whereas for backyard poultry it is moderate to high depending on proximity to wetlands and the presence of species that could increase the likelihood of contact with wild birds such as domestic duck. The magnitude of the biological and economic consequences of successful transmission to poultry or wild birds would be low to severe depending on the probability of the occurrence of outbreak scenarios described. As a result, the risk estimate is greater than negligible, and HPAI H5N1 prevention strategy in the region should always be carefully considered by the veterinary services in Brazil.

Videolaryngostroboscopy and voice evaluation in patients with rheumatoid arthritis

Arthritis may affect the larynx and produce symptoms such as hoarseness and vocal fatigue. Objective: This paper aimed to evaluate the laryngeal manifestations of rheumatoid arthritis. Methods: This is prospective study assessed 27 patients with rheumatoid arthritis with the aid of videolaryngostroboscopy, auditory-perceptual analysis of the speech using the GIRBAS scale, acoustic analysis and the Voice Handicap Index questionnaire. Results: Nineteen patients had laryngeal complaints, the main ones being intermittent dysphonia and sensation of a foreign body in the throat. The most frequent laryngoscopical finding was overlapping arytenoids. Three patients had low pitch, nine patients had mild dysphonia and roughness. Median acoustic measures were: F0, 198.39 Hz; Jitter, 0.815; Shimmer, 4.915; and NHR, 0.144. Regarding the Voice Handicap Index, the median score was zero in all domains. There was a statistically significant correlation between voice complaints and the domains of this index. Functional classes were significantly correlated to: overlapping arytenoids (p = 0.001), PPQ (p = 0.0257), Shimmer (p = 0.0295), APQ (p = 0.0195), and the VHI physical (p = 0.0227) and total domains (p = 0.0425). Conclusion: Laryngeal complaints were reported by 70.4% of the patients and laryngoscopical alterations were observed in 48% of the subjects. Voice acoustic evaluation and self-perception were altered.

Identification of Leishmania infantum chagasi proteins in urine of patients with visceral leishmaniasis: a promising antigen discovery approach of vaccine candidates

Visceral leishmaniasis (VL) is a serious lethal parasitic disease caused by Leishmania donovani in Asia and by Leishmania infantum chagasi in southern Europe and South America. VL is endemic in 47 countries with an annual incidence estimated to be 500 000 cases. This high incidence is due in part to the lack of an efficacious vaccine. Here, we introduce an innovative approach to directly identify parasite vaccine candidate antigens that are abundantly produced in vivo in humans with VL. We combined RP-HPLC and mass spectrometry and categorized three L. infantum chagasi proteins, presumably produced in spleen, liver and bone marrow lesions and excreted in the patients urine. Specifically, these proteins were the following: Li-isd1 (XP_001467866.1), Li-txn1 (XP_001466642.1) and Li-ntf2 (XP_001463738.1). Initial vaccine validation studies were performed with the rLi-ntf2 protein produced in Escherichia coli mixed with the adjuvant BpMPLA-SE. This formulation stimulated potent Th1 response in BALB/c mice. Compared to control animals, mice immunized with Li-ntf2+ BpMPLA-SE had a marked parasite burden reduction in spleens at 40 days post-challenge with virulent L. infantum chagasi. These results strongly support the proposed antigen discovery strategy of vaccine candidates to VL and opens novel possibilities for vaccine development to other serious infectious diseases.

Le strategie di internazionalizzazione delle imprese distrettuali: un'analisi comparata di tre diversi sistemi locali di produzione in Emilia Romagna

Since the Nineties, the process of globalization has caused a sharp increase in the real and financial integration of the worldwide economy, reducing the obstacles to international trade and minimizing the cost of transaction. The entrance of foreign firms in the domestic market has deeply modified the competitive situation of Italian enterprises, which have been forced to change their strategies in order to cope with those of the new competitors. In this scenario, internationalization is no longer one of the different strategic options available for the firm, but it becomes a forced choice to maintain or acquire a competitive advantage sustainable over time. Internationalization strategies of SMEs, however, are hindered by the shortage of financial resources and entrepreneurial skills, therefore this kind of firms tends toward light forms of foreign expansion, like export and subcontracting. Despite this, many studies have demonstrated that the district localisation increases the firms’ productivity and innovative capacity, so their competiveness both at a domestic and international level. The majority of these empirical contributions has focused mainly on the analysis of commercial flows, confirming that district enterprises reach a superior international performance compared to their external competitors. On the contrary, only few works have tried to evaluate the existence of a district effect on the firms’ ability to invest abroad, but the obtained results are not straightforward. One of the reason of these conclusions is that the phenomena has been analysed without taking into account the differences existing between districts in terms of enterprises’ dimension, diffusion of industrial groups and, above all, the sector of productive specialization, because the technological content of production could improve the innovativeness of district firms, allowing them to adopt advanced forms of internationalisation as foreign direct investments (FDI). The aim of the thesis is to further investigate the district effect on internationalisation, trough an econometric analysis of the international strategies carried out by firms localised in three different local system of production characterised by different technological specialization.

Point defects in carbon nanostructures studied by in-situ electron microscopy

In the present work, the formation and migration of point defects induced by electron irradiation in carbon nanostructures, including carbon onions, nanotubes and graphene layers, were investigated by in-situ TEM. The mobility of carbon atoms normal to the layers in graphitic nanoparticles, the mobility of carbon interstitials inside SWCNTs, and the migration of foreign atoms in graphene layers or in layers of carbon nanotubes were studied. The diffusion of carbon atoms in carbon onions was investigated by annealing carbon onions and observing the relaxation of the compressed clusters in the temperature range of 1200 – 2000oC. An activation energy of 5.0±0.3 eV was obtained. This rather high activation energy for atom exchange between the layers not only prevents the exchange of carbon atoms between the layers at lower temperature but also explains the high morphological and mechanical stability of graphite nanostructures. The migration of carbon atoms in SWCNTs was investigated quantitatively by cutting SWCNT bundles repeatedly with a focused electron beam at different temperatures. A migration barrier of about 0.25 eV was obtained for the diffusion of carbon atoms inside SWCNTs. This is an experimental confirmation of the high mobility of interstitial atoms inside carbon nanotubes, which corroborates previously developed theoretical models of interstitial diffusivity. Individual Au and Pt atoms in one- or two-layered graphene planes and MWCNTs were monitored in real time at high temperatures by high-resolution TEM. The direct observation of the behavior of Au and Pt atoms in graphenic structures in a temperature range of 600 – 700°C allows us to determine the sites occupied by the metal atoms in the graphene layer and the diffusivities of the metal atoms. It was found that metal atoms were located in single or multiple carbon vacancies, not in off-plane positions, and diffused by site exchange with carbon atoms. Metal atoms showed a tendency to form clusters those were stable for a few seconds. An activation energy of around 2.5 eV was obtained for the in-plane migration of both Au and Pt atoms in graphene (two-dimensional diffusion). The rather high activation energy indicates covalent bonding between metal and carbon atoms. Metal atoms were also observed to diffuse along the open edge of graphene layers (one-dimensional diffusion) with a slightly lower activation energy of about 2.3 eV. It is also found that the diffusion of metal atoms in curved graphenic layers of MWCNTs is slightly faster than in planar graphene.

Transatlantic negotiations on "hell"?: W. E. B. Du Bois's visit to fascist Germany and Theodor W. Adorno's exile in the land of the culture industry

In 1936, the African-American intellectual W.E.B. Du Bois visited Nazi Germany for a period of five months. Two years later, the eleven-year-long American exile of the German philosopher Theodor W. Adorno began. From the latter’s perspective, the United States was the “home” of the Culture Industry. One intuitively assumes that these sojourns abroad must have amounted to “hell on earth” for both the civil rights activist W.E.B. Du Bois and the subtle intellectual Adorno. But was this really the case? Or did they perhaps arrive at totally different conclusions? This thesis deals with these questions and attempts to make sense of the experiences of both men. By way of a systematic and comparative analysis of published texts, hitherto unpublished documents and secondary literature, this dissertation first contextualizes Du Bois’s and Adorno’s transatlantic negotiations and then depicts them. The panoply of topics with which both men concerned themselves was diverse. In Du Bois’s case it encompassed Europe, science and technology, Wagner operas, the Olympics, industrial education, race relations, National Socialism and the German Africanist Diedrich Westermann. The opinion pieces which Du Bois wrote for the newspaper “Pittsburgh Courier” during his stay in Germany serve as a major source for this thesis. In his writings on America, Adorno concentrated on what he regarded as the universally victorious Enlightenment and the predominance of mass culture. This investigation also sheds light on the correspondences between the philosopher and Max Horkheimer, Thomas Mann, Walter Benjamin, Siegfried Kracauer and Oskar and Maria Wiesengrund. In these autobiographical texts, Adorno’s thoughts revolve around such diverse topics as the American landscape, his fears as German, Jew and Left-Hegelian as well as the loneliness of the refugee. This dissertation has to refute the intuitive assumption that Du Bois’s and Adorno’s experiences abroad were horrible events for them. Both men judged the foreign countries in which they were staying in an extremely differentiated and subtle manner. Du Bois, for example, was not racially discriminated against in Germany. He was also delighted by the country’s rich cultural offerings. Adorno, for his part, praised the U.S.’s humanity of everyday life and democratic spirit. In short: Although both men partly did have to deal with utterly negative experiences, the metaphor of “hell on earth” is simply untenable as an overall conclusion.

An Innovation System Perspective on Adaptation Strategies to Climate Variability and Water Management in India

Government policies play a critical role in influencing market conditions, institutions and overall agricultural productivity. The thesis therefore looks into the history of agriculture development in India. Taking a political economy perspective, the historical account looks at significant institutional and technological innovations carried out in pre- independent and post independent India. It further focuses on the Green Revolution in Asia, as forty years after; the agricultural community still faces the task of addressing recurrent issue of food security amidst emerging challenges, such as climate change. It examines the Green Revolution that took place in India during the late 1960s and 70s in a historical perspective, identifying two factors of institutional change and political leadership. Climate change in agriculture development has become a major concern to farmers, researchers and policy makers alike. However, there is little knowledge on the farmers’ perception to climate change and to the extent they coincide with actual climatic data. Using a qualitative approach,it looks into the perceptions of the farmers in four villages in the states of Maharashtra and Andhra Pradesh. While exploring the adaptation strategies, the chapter looks into the dynamics of who can afford a particular technology and who cannot and what leads to a particular adaptation decision thus determining the adaptive capacity in water management. The final section looks into the devolution of authority for natural resource management to local user groups through the Water Users’ Associations as an important approach to overcome the long-standing challenges of centralized state bureaucracies in India. It addresses the knowledge gap of why some local user groups are able to overcome governance challenges such as elite capture, while others-that work under the design principles developed by Elinor Ostrom. It draws conclusions on how local leadership, can be promoted to facilitate participatory irrigation management.

La competenza comunicativa in giapponese: indagine empirica sulle difficoltà frequenti degli apprendenti italofoni in interazioni orali

Smooth intercultural communication requires very complex tasks, especially when participants are very different in their cultural and linguistic backgrounds: this is the case of native Italian and Japanese speakers. A further difficulty in such a context can be found in the usage of a foreign language not mastered perfectly by speakers, which is the case for Italian intermediate learners of Japanese. The aim of this study is therefore to identify the linguistic difficulties common among Italian learners of Japanese as a foreign language and to further examine the consequences of incorrect pragma-linguistic deliveries in actual conversations. To this end, a series of linguistic aspects selected on the basis of the author's experience have been taken into consideration. Some aspects are expected to be difficult to master because of linguistic differences between Italian and Japanese, while some may be difficult due to their connection to the specific Japanese cultural context. The present study consists of six parts. The Introduction presents the state of the art on the research topic and defines the purpose of this research. Chapter 1 outlines the linguistic aspects of the Japanese language investigated in the study, specifically focusing on the following topics: writing system, phonology, loan words, numbers, ellipsis, levels of speech and honorifics. Chapter 2 presents an overview of the environment of teaching Japanese as a foreign language in the university setting in Italy. In Chapter 3 the first phase of the research is described, i.e. an online survey aimed at identifying the most problematic linguistic aspects. Chapter 4 presents the second phase of this study: a series of oral interactions between Japanese and Italian native speakers, conversing exclusively in Japanese, focusing on the management of misunderstandings with the use of actual linguistic data. The Conclusion outlines the results and possible future developments.

Similarities and differences between physician and non-physician acupuncturists in using diagnostic methods - an explorative study

Purpose: Acupuncture is one of the complementary medicine therapies with the greatest demand in Switzerland and many other countries in the West and in Asia. Over the past decades, the pool of scientific literature in acupuncture has markedly increased. The diagnostic methods upon which acupuncture treatment is based, have only been addressed sporadically in scientific journals. The goal of this study is to assess the use of different diagnostic methods in the acupuncture practices and to investigate similarities and differences in using these diagnostic methods between physician and non-physician acupuncturists. Methods: 44 physician acupuncturists with certificates of competence in acupuncture – traditional chinese medicine (TCM) from ASA (Assoziation Schweizer Ärztegesellschaften für Akupunktur und Chinesische Medizin: the Association of Swiss Medical Societies for Acupuncture and Chinese Medicine) and 33 non-physician acupuncturists listed in the EMR (Erfahrungsmedizinisches Register: a national register, which assigns a quality label for CAM therapists in complementary and alternative medicine) in the cantons Basel-Stadt and Basel-Land were asked to fill out a questionnaire on diagnostic methods. The responder rate was 46.8% (69.7% non-physician acupuncturists and 29, 5% physician acupuncturists). Results: The results show that both physician and non-physician acupuncturists take patients’ medical history (94%), use pulse diagnosis (89%), tongue diagnosis (83%) and palpation of body and ear acupuncture points (81%) as diagnostic methods to guide their acupuncture treatments. Between the two groups, there were significant differences in the diagnostic tools being used. Physician acupuncturists do examine their patients significantly more often with western medical methods (p<.05) than this is the case for nonphysician acupuncturists. Non-physician acupuncturists use pulse diagnosis more often than physicians (p<.05). A highly significant difference was observed in the length of time spent with collecting patients’ medical history, where nonphysician acupuncturists clearly spent more time (p<.001). Conclusion: Depending on the educational background of the acupuncturist, different diagnostic methods are used for making the diagnosis. Especially the more time consuming methods like a comprehensive anamnesis and pulse diagnosis are more frequently employed by non-physician practitioners. Further studies will clarify if these results are valid for Switzerland in general, and to what extent the differing use of diagnostic methods has an impact on the diagnosis itself and on the resulting treatment methods, as well as on the treatment success and the patients’ satisfaction.
