History of insecticide resistance of Triatominae vectors

AbstractIn the last 15 years, different types of Triatominae resistance to different insecticides have been reported; thus, resistance may be more widespread than known, requiring better characterization and delimitation, which was the aim of this review. This review was structured on a literature search of all articles from 1970 to 2015 in the PubMed database that contained the keywords Insecticide resistance and Triatominae . Out of 295 articles screened by title, 33 texts were selected for detailed analysis. Insecticide resistance of Triatomines is a complex phenomenon that has been primarily reported in Argentina and Bolivia, and is caused by different factors (associated or isolated). Insecticide resistance of Triatominae is a characteristic inherited in an autosomal and semi-dominant manner, and is polygenic, being present in both domestic and sylvatic populations. The toxicological profile observed in eggs cannot be transposed to different stages of evolution. Different toxicological profiles exist at macro- and microgeographical levels. The insecticide phenotype has both reproductive and developmental costs. Different physiological mechanisms are involved in resistance. Studies of Triatomine resistance to insecticides highlight three deficiencies in interpreting the obtained results: I) the vast diversity of methodologies, despite the existence of a single guiding protocol; II) the lack of information on the actual impact of resistance ratios in the field; and III) the concept of the susceptibility reference lineage. Research on the biological and behavioral characteristics of each Triatominae species that has evolved resistance is required in relation to the environmental conditions of each region.

Chagas disease in the State of Amazonas: history, epidemiological evolution, risks of endemicity and future perspectives

Chagas disease (CD) is a parasitic infection that originated in the Americas and is caused by Trypanosoma cruzi. In the last few years, the disease has spread to countries in North America, Asia and Europe due to the migration of Latin Americans. In the Brazilian Amazon, CD has an endemic transmission, especially in the Rio Negro region, where an occupational hazard was described for piaçaveiros (piassaba gatherers). In the State of Amazonas, the first chagasic infection was reported in 1977, and the first acute CD case was recorded in 1980. After initiatives to integrate acute CD diagnostics with the malaria laboratories network, reports of acute CD cases have increased. Most of these cases are associated with oral transmission by the consumption of contaminated food. Chronic cases have also been diagnosed, mostly in the indeterminate form. These cases were detected by serological surveys in cardiologic outpatient clinics and during blood donor screening. Considering that the control mechanisms adopted in Brazil's classic transmission areas are not fully applicable in the Amazon, it is important to understand the disease behavior in this region, both in the acute and chronic cases. Therefore, the pursuit of control measures for the Amazon region should be a priority given that CD represents a challenge to preserving the way of life of the Amazon's inhabitants.

IPO impact on industry incumbents

The creation of an innovative company is suggestive of change in an industry. To test that change this paper tests the impact of IPOs on industry incumbents. IPOs are found to happen in industries that exhibited positive abnormal returns for up to 5 years before the IPO date. The IPO date is found to coincide with the end of that industry abnormal return profile. This paper suggests this evidence is consistent with the IPO acting as mechanism of enforcing market efficiency at the industry level.

Natural history of stenosis in the iliac arteries in patients with intermittent claudication undergoing clinical treatment

PURPOSE: Inspite of the long experience with the treatment of intermittent claudication, little is known about the natural history of stenotic lesions in the iliac segment. With the advent of endovascular treatment, this knowledge has become important. METHODS: Fifty-two stenosis, diagnosed using arteriography, in 38 claudicant patients were analyzed. After a minimum time interval of 6 months, a magnetic resonance angiography was performed to determine whether there was arterial occlusion. The primary factors that could influence the progression of a stenosis were analyzed, such as risk factors (smoking, hypertension, diabetes, sex, and age), compliance with clinical treatment, initial degree of stenosis, site of the stenosis, and length of follow-up. RESULTS: The average length of follow-up was 39 months. From the 52 lesions analyzed, 13 (25%) evolved to occlusion. When occlusion occurred, there was clinical deterioration in 63.2% of cases. This association was statistically significant (P = .002). There was no statistically significant association of the progression of the lesion with the degree or site of stenosis, compliance with treatment, or length of follow-up. Patients who evolved to occlusion were younger (P = .02). The logistic regression model showed that the determinant factors for clinical deterioration were arterial occlusion and noncompliance with clinical treatment. CONCLUSIONS: The progression of a stenosis to occlusion, which occurred in 25% of the cases, caused clinical deterioration. Clinical treatment was important, but it did not forestall the arterial occlusion. Prevention of occlusion could be achieved by early endovascular intervention or with the development of drugs that might stabilize the atherosclerotic plaque.

Portuguese plain architecture: history opening a closed sequence

The paper will address George Kubler’s Portuguese Plain Architecture [PPA] (1972) and its effect in Portuguese architectural practice. Kubler’s philosophy of art history implied that closed sequences of objects could be opened by several reasons. Thus, it will be argued that there is an effect upon Portuguese architecture post 1974, that is apparent by the reemergence of some of the form classes treated by Kubler. This was mostly achieved through the popularity of Kubler’s book within architectural practice, scholarship and moreover by the establishment of the term “Plain Architecture” in portuguese architectural vocabulary. Plain Architecture of the seventeenth and eighteenth centuries shared some qualities with the architecture to be built in post‑revolutionary Portugal, most importantly the effect that could be achieved with low budget buildings that were responding to a situation of crisis, and simultaneously exhaled aristocratic sparsity. The connection of PPA with the ideological attributes of early modernism and the political context of the time catalysed the reemergence of a new order of Portuguese Plain that resonates still in contemporary architecture.

The names of things: terminology and the practice of art history

This paper aims to explore the ways in which standard art history terminology shapes the practice of art history by conditioning the interpretation of specific works of art and, in certain cases, the definition of a research subject (especially where questions of genre and periodization are concerned). Taking as a case study a painting by Georges de La Tour, the Peasant Couple Eating, I will argue that terms such as realism, realistic, naturalistic etc. used for its description and/or interpretation, far from constituting objective stylistic characterizations, shape our perception of the work in question. Bringing the question of social class to the center of the discourse on realism, I propose to show how the social divide between the painter and his subject matter (in this case, the peasants) is internalized in the painting’s style and meaning, and how it is fundamental for the understanding of its intentionality and function.

History of Art and Art Criticism: A System in Crisis

This article aims to reconstruct the critical debate regarding the examination of the crisis in the disciplines of art history and criticism with a particular focus on the proposal formulated by U.S. theorists who contributed to October journal. The discrediting of many modernist critical methods, particularly that of Clement Greenberg – the formalist diktat – marked the birth of the journal and gave rise to proposals set forth by critics committed to a new approach. Their divergent positions, nonetheless, have contributed to undermining the traditional concepts of the autonomy of art and criticism. The proposals discussed over the course of publication were the result of a reappraisal of the disciplinary instruments of art history and criticism pursuant to the crucial cultural changes which took place in the 1980s.

The effect of music marketing: A consumer perspective

The purpose of this thesis is to get a consumer perspective regarding event marketing in music festivals. Event marketing is a tool used by marketers that evolved out of philanthropy and commercial sponsorship. Brands are more and more using music or other entertainment moments to create a strong relationship with their clients, and the target group at these events, the millennial generation. Brands use sponsoring and therefore event marketing for several reasons as: increase brand awareness; create brand image; re-position the brand/product in the minds of consumers; increase profit over a short period; and, achieve larger market share. Nonetheless, we wonder how is this tool seen by consumers? To understand this, a preliminary research with nine interviews was conducted to obtain basic ideas about event marketing. Afterwards the main research was developed, also using interviews, to get deeper insights. With this thesis, it is possible to conclude that some brands are able to create brand awareness on attendees through brand sponsorship. Moreover, entertainment activities in festivals are well seen by consumers, they like it and are able to describe it well, even though it is more about the activity itself than the brand promoting it. Furthermore, it was possible to understand that experiential marketing in a festival might have a positive effect on consumers as it might create a link between the event and the brand. Finally, we recommend some actions, for brands to develop in future music festivals.

The hospitality industry

This study of independent Portuguese hotels‘ positioning strategies regarding adopting, or not, a soft brand affiliation seeks to determine what motivates this choice. Surveyed hotels were asked to enunciate the benefits and disadvantages associated with their strategic decision, and other difficulties experienced in their business. The results indicate that international brand awareness and the hotel owners‘ long-term goals are the core factors affecting the choice. In practice, we conclude that there isn‘t a ‗one size fits all‘ strategy. Nevertheless, affiliated hotels experience an operational advantage over non-affiliated ones stemming from the affiliating organization‘s accumulated experience in sales, distribution channels and marketing resources.

The relationship between liquidity and profitability in the food & beverage industry evidence from Europe and United States

This Work Project clarifies the relationship between liquidity and profitability based on a sample in the Food & Beverage (F&B) industry, and comparing the largest European and United States companies. The research concludes that liquidity, proxied by current ratio or quick ratio, correlates with return on assets taken as the measure of profitability, and so does the cash conversion cycle and its components. Moreover, company size correlates with liquidity, and indirectly affects ROA. This research contributes and addresses to managers in the F&B industry and recommends how they should act in order to improve profitability in the industry.
