Inflation targeting, credibility and coordination aspects

There are plenty of economic studies pointing out some requirements, like the inexistence of fiscal dominance, for inflation targeting framework be implemented in successful (credible) way. Essays on how public targets could be used in the absence of such requirements are unusual. In this papel' we appraise how central banks could use inflation targeting before soundness economic fundamentaIs have been achieved. First, based on concise framework, where confidence crises and imperfect information are neglected, we conclude that less ambitious (greater) target for inflation increases the credibility in the precommitment. Optimal target is higher than the one obtained using the Cukierman-Liviatan [7] model, where increasing credibility effect is not considered. Second, extending the model to make confidence crises possible, multiple equilibria solutions becomes possible too. In this case, to set greater targets for inflation may stimulate confidence crises and reduce the policymaker credibility. On the other hand, multiple (bad) equilibria may be avoided. The optimal target depends on the likelihood of each equilibrium be selected. Finally, when perturbing common knowledge uniqueness is restored even considering confidence crises, as in Morris-Shin[ 14]. The first result, i.e. less ambitious target for inflation increases credibility in precommitment, is also recovered. Adding a precise public signal, cOOl'dinated self-fulfilling actions and equilibrium multiplicity may still exist for some lack of common knowledge (as in Angeleto and Weming[l]). In this case, to set greater targets for inflation may stimulate confidence crisis again, reducing the policymaker credibility. From another aspect, multiple (bad) equilibria may be avoided. Optimal policy prescriptions depend on the likelihood of each equilibrium be selected. Results also indicate that more precise public information may open the door for bad equilibrium, contrary to the conventional wisdom that more central oank transparency is always good when considering inflation targeting framework.

PRESYNAPTIC AND POSTSYNAPTIC MECHANISMS INVOLVED IN TETANIC FADE INDUCED BY PANCURONIUM IN THE ISOLATED RAT MUSCLE

The mechanisms underlying the fade of the tetanic contraction induced by pancuronium were studied in vitro by means of myographical and electrophysiological techniques in the extensor digitorum longus muscle of the rat. Pancuronium (0.5 mu mol/l) induced a complete fade of the tetanic contraction while leaving the twitch unaffected. At the same concentration it decreased the amplitude and increased the tetanic rundown of trains of endplate potentials (e.p.ps) evoked in the frequency of 50 Hz. The electrophysiological changes induced by pancuronium were due to decreases in both quantal sizes and quantal contents of the e.p.ps. The former effect was the result of a postsynaptic competitive action and the latter of a presynaptic inhibitory action of that compound. The decrease in quantal. content affected the e.p.ps starting from the first in the train and became larger during the generation of the sequence of e.p.ps. This intensified their tetanic rundown. It is concluded that the fade of the tetanic contraction induced by pancuronium is due to a summation of pre- and postsynaptic actions and, therefore, not only to an increase in the tetanic rundown of e.p.ps. Possible explanations for the distinct abilities of neuromuscular blockers in affecting tetani and twitches in a differential manner are also discussed.

Sedative and cardiorespiratory effects of acepromazine or atropine given before dexmedetomidine in dogs

To test the hypothesis that acepromazine could potentiate the sedative actions and attenuate the pressor response induced by dexmedetomidine, the effects of acepromazine or atropine were compared in six healthy adult dogs treated with this alpha(2)-agonist. In a randomised block design, the dogs received intravenous doses of either physiological saline, 0.05 mg/kg acepromazine or 0.04 mg/kg atropine, 15 minutes before an intravenous dose of 5 mu g/kg dexmedetomidine. The dogs' heart rate was reduced by 50 to 63 per cent from baseline and their mean arterial blood pressure was increased transiently from baseline for 20 minutes after the dexmedetomidine. Atropine prevented the alpha(2)-agonist-induced bradycardia and increased the severity and duration of the hypertension, but acepromazine did not substantially modify the cardiovascular effects of the a2-agonist, except for a slight reduction in the magnitude and duration of its pressor effects. The dexmedetomidine induced moderate to intense sedation in all the treatments, but the dogs' sedation scores did not differ among treatments. The combination of acepromazine with dexmedetomidine had no obvious advantages in comparison with dexmedetomidine alone, but the administration of atropine before dexmedetomidine is contraindicated because of a severe hypertensive response.

Profile evaluation of orthodontic professionals as for their legal actions

Objective: Evaluate the legal actions and behavior in the doctor/patient relationship, used by dental surgeons practicing orthodontics. Methods: The population sample of the present study consisted of dental surgeons, active in the field of orthodontics, and registered with Dental Press Publishing Company - Maringá/PR, Brazil, with a total sample size of 525 professionals. The research was conducted using a 17-question survey forwarded to these professionals. Results and Conclusions: The majority of participants in our study are specialized in orthodontics; 75% of professionals use some sort of contract at the office/clinic; 73.7% of professionals periodically request maintenance X-rays; a large percentage of professionals (58.9%) keep patient records on file for life. The interviewed professionals demonstrate good knowledge of the Brazilian Code of Ethics in Dentistry, especially of Chapter XIV - on Communication.

A Framework to Optimize Biodiversity Restoration Efforts Based on Habitat Amount and Landscape Connectivity

The effectiveness of ecological restoration actions toward biodiversity conservation depends on both local and landscape constraints. Extensive information on local constraints is already available, but few studies consider the landscape context when planning restoration actions. We propose a multiscale framework based on the landscape attributes of habitat amount and connectivity to infer landscape resilience and to set priority areas for restoration. Landscapes with intermediate habitat amount and where connectivity remains sufficiently high to favor recolonization were considered to be intermediately resilient, with high possibilities of restoration effectiveness and thus were designated as priority areas for restoration actions. The proposed method consists of three steps: (1) quantifying habitat amount and connectivity; (2) using landscape ecology theory to identify intermediate resilience landscapes based on habitat amount, percolation theory, and landscape connectivity; and (3) ranking landscapes according to their importance as corridors or bottlenecks for biological flows on a broader scale, based on a graph theory approach. We present a case study for the Brazilian Atlantic Forest (approximately 150 million hectares) in order to demonstrate the proposed method. For the Atlantic Forest, landscapes that present high restoration effectiveness represent only 10% of the region, but contain approximately 15 million hectares that could be targeted for restoration actions (an area similar to today's remaining forest extent). The proposed method represents a practical way to both plan restoration actions and optimize biodiversity conservation efforts by focusing on landscapes that would result in greater conservation benefits. © 2013 Society for Ecological Restoration.

Environmental conservation and the Cerrado Biome: investigating knowledge and attitudes of Bauru residents

In today’s context of environmental degradation, environmental issues have increasingly become a focus of global discussion. Although many researchers emphasize the importance of knowledge and information in promoting environmental protection, research involving people’s notions about and attitudes toward the environment and establishing their connection with such knowledge is scarce. This lack of research led to the following inquiry: Is it possible to relate conservation actions and concern about a biome – in this case, the Cerrado – to the population’s level of knowledge about the environment in which they live? This research presents results from an investigation conducted in a representative population sample in Bauru, where there are fragments of a Cerrado Legal Reserve. The sampling approach used was probabilistic; it is based on random laws and can be submitted to statistical methods. The total sample (450 people) was divided into 90 people per Bauru region, 45 people female and 45 males. Each gender group was divided into three age groups: the first from 16 to 30 years, the second from 31 to 55 years and the third above 56 years. Through the questionnaire, we collected the following data from respondents: personal data such as salary, gender, age, level of education, notions/actions and intentions related to environmental conservation and general knowledge about the Cerrado. The result of the chi-square analysis is consistent with this finding, as it is less than 0.05, demonstrating a significant association between these two variables.

The production of critical-reflexive narratives and their effect on nursing students' portfolios

The objective of this study is to analyze the process of producing reflexive narratives on nursing students' portfolios. This qualitative study performed an analysis of the portfolios of the class discipline Health Promotion in Primary Education, taught in the fourth semester of the Nursing Licensure Course. Results showed an initial predominance of descriptive records, with the incipient approach of theoretical aspects associated with the aspects regarding their experience. Further, in the group and experience discussions, there were narratives containing more critical and reflexive elements, with justifications for the described actions and the relationships with the theoretical-practical aspects studied in the class and in the course. In conclusion, there is a process of producing critical-reflexive narratives in portfolios that could include a summarized description, using common sense and idealization which allows for including the differences and the theoretical review.
