OBJECTIVE: To evaluate whether sites with large amount of potential breeding sites for immature forms of Aedes aegypti, called strategic points, influence in the active vector’s dispersion into properties in their surroundings. METHODS: We selected four areas in the municipality of Campinas, three of them with strategic points classified as high, moderate, and low risk according to infestation and a control area, without strategic points. Between October 2015 and September 2016, we monthly installed oviposition traps and evaluated the infestation by Ae. aegypti in all properties of each selected area. To verify if there was vector dispersion from each strategic point, based on its location, we investigated the formation of clusters with excess of eggs or larvae or pupae containers, using the Gi spatial statistics. RESULTS: The amount of eggs collected in the ovitraps and the number of positive containers for Ae. aegypti did not show clusters of high values concerning its distance from the strategic point. Both presented random distribution not spatially associated with the positioning of strategic points in the area. CONCLUSIONS: Strategic points are not confirmed as responsible for the vector’s dispersion for properties in their surroundings. We highlight the importance of reviewing the current strategy of the vector control program in Brazil, seeking a balance from the technical, operational, and economic point of view, without disregarding the role of strategic points as major producers of mosquitoes and their importance in the dissemination of arboviruses in periods of transmission.

Mosquitoes can act as vectors for many disease-causing viruses and parasites through carrying these organisms from person to person. The objective of this study was to evaluate the susceptibility of Aedes aegypti larvae to some insecticides in Jeddah Governorate. Mosquito larvae were collected from all the available breeding sites in Jeddah municipalities using standard larval collection kits. The diagnostic doses (LC50 and LC90) were calculated from the mortality and concentration data. The larvicides Pirimiphos methyl, Fenitrothion, Bifenthrin and Cypermethrin were tested against the larvae of Ae. aegypti mosquito. The results showed positive correlation between the concentrations under investigation and mortality% of the treated larvae. Cypermethrin gave strong effect against Ae. aegypti larvae (LD50 0.0015 ml/L) followed by Pirimiphos methyl (LD50 0.0020 ml/L), Bifenthrin (LD50 0.039 ml/L), and at last rank Fenitrothion (0.041 ml/L). The same trend was obtained in LD90s. Ae. aegypti in Jeddah was susceptible to Bifenthrin, Cypermethrin, Pirimiphos methyl and Fenitrothion. Further studies should be run to conduct an intensive and appropriate vector control program in Jeddah Governorate.

Educational Aspect

Society has changed dramatically in recent decades not only from the demographic, social and economic point of view, but also from the educational aspect. The current population has higher levels of education than in previous times and can access information in a relatively easy way. In addition, the relationship between the healthcare professional and the patient has evolved from the paternalistic medicine to a more informed and participatory patient-provider relationship. Patient participation and empowerment in the health decision-making process means that the patient has the opportunity to share his/her opinion, knowledge, experience and expectations with other patients, as well as with the health professionals in order to make informed decisions. With this evolution of the role of the patient in the current society, patients have asked for multidisciplinary and coordinated work among professionals to respond to their needs for diagnosis, control and treatment. Patient's participation and empowerment can be conducted both, in the management of the disease, as well as helping to improve different aspects of health services. Participation and empowerment also mean representing other patients. In all cases, patients’ education and training, using clear and plain language, and patients’ confidence play a pivotal role. The aim of this review is to present a summary of the scope of the situation regarding patients’ empowerment and education.

In this contribution we focus on the role of experts in the assessment of tort damages from an economic point of view. We distinguish two different aspects.First, we examine the role which economists might play in assessing damages in tort cases. This approach focuses on the insights that Law and Economics provides regarding the correct assessment of damages. We pay specific attention to two problematic forms of losses where economic insights may play an important role: pure economic loss and personal injury damage (both loss of income and compensation for immaterial losses due to fatal and non-fatal accidents).Second, we investigate from a Law and Economics point of view the role of experts in general (not only economists) in the assessment of damages. We discuss i.a. the question why experts may be involved in the assessment of damages, the potential problems (and the possible solutions) when using experts, and differences between party appointed experts and court appointed experts.It turns out that the economic analysis can provide a different, insightful viewpoint in some respects, such as the fact that market based mechanisms may help to provide incentives to party appointed experts to provide an accurate and objective damage assessment.

Dengue Epidemics

During the past ten years, the islands of Guadeloupe (French West Indies) are facing dengue epidemics with increasing numbers of cases and fatal occurrences. The vectorAedes aegyptiis submitted to intensive control, with little effect on mosquito populations. The hypothesis that importantAe. aegyptibreeding sites are not controlled is investigated herein. For that purpose, the roof gutters of 123 houses were systematically investigated, and the percentage of gutters positive forAe. aegyptivaried from 17.2% to 37.5%, from humid to dry locations. In the dryer location, most of houses had no other breeding sites. The results show that roof gutters are becoming the most importantAe. aegyptibreeding sites in some locations in Guadeloupe, with consequences on dengue transmission and vector control.

Purpose The purpose of this paper is to explain the significance of cascading crises for translators and interpreters, and how their work may be affected by such events. It provides a theoretical basis for analysis and field practice. Design/methodology/approach The authors define cascades and explain how they influence the development of preparedness, mitigation and response. The authors identify key drivers of cascading crises and discuss how they challenge conventional approaches to emergency management. The authors discuss ways in which use of language could be a key factor in crisis escalation. The authors define priorities and operational challenges of cascading crises for translators and interpreters. In terms of methodology, this paper develops a conceptual framework that can be used for future enquiry and case history analysis. Findings The authors provide a qualitative description and synthesis of the key instructions to be used in the field. The authors offer a short list of key questions that can be referred to by linguists and scholars. The authors identify situations in which translation and interpretation are important ingredients in the success of emergency preparedness and response efforts. These include multilingual populations, migrant crises, international humanitarian deployment and emergency communication during infrastructure failures. Research limitations/implications This work has academic value for the process of understanding cascades and practical relevance in terms of how to deal with them. Practical implications Translators and interpreters need to understand cascading crises in order to be prepared for the challenges that such events will present. Social implications Society has become more complex and interconnected, with non-linear cascading escalation of secondary emergencies. Emergency planners and responders need to address this in new ways. Effective communication and information strategies are essential to the mitigation of cascading disaster risk. Originality/value The study of cascading crises from a socio-economic point of view is relatively new, but it is important because society is increasingly dependent on networks that can propagate failure of information supply.

Gravid Females

Mass trapping of gravid females represents one promising strategy for the development of sustainable tools against Aedes aegypti. However, this technique requires the development of effective odorant lures that can compete with natural breeding sites. The presence of conspecific larvae has been shown to stimulate oviposition. Hence, we evaluated the role of four major molecules previously identified from Ae. aegypti larvae (isovaleric, myristoleic, myristic [i.e. tetradecanoic], and pentadecanoic acids) on the oviposition of conspecific females, as well as their olfactory perception to evaluate their range of detection. Using flight cage assays, the preference of gravid females to oviposit in water that previously contained larvae (LHW) or containing the four larval compounds was evaluated. Then, compounds and doses inducing the highest stimulation were challenged for their efficacy against LHW. Only isovaleric acid elicited antennal response, suggesting that the other compounds may act as taste cues. Pentadecanoic acid induced significant oviposition stimulation, especially when dosed at 10 ppm. Myristoleic acid and isovaleric acid deterred oviposition at 10 and 100 ppm, while no effect on oviposition was observed with myristic acid irrespectively of the dose tested. When the four compounds were pooled to mimic larvae’s chemical signature, they favored oviposition at 1 ppm but negatively affected egg-laying at higher concentrations. When properly dosed, pentadecanoic acid and the blend of compounds may be promising lures for ovitraps as they could compete with LHW. Due to their low volatility, their effect should be further evaluated under field conditions, in addition with long-range attractants for developing effective tools against gravid females.

The article is devoted to the role of HR audit in creating an effective HR policy in the context of innovative transformations. Since the role of a person in production is constantly increasing, personnel management is becoming the most important factor in modern management. The staff is not always ready for changes and so-called innovations (changes) in the organization or enterprise. HR audit helps to build the work so that it is most effective both from an economic point of view for the organization itself, and in psychological and social terms for the staff. The structure and some criteria of HR audit are described. Possible results of the audit in the field of personnel and stages of its implementation are given.
