Compliance to law and effectiveness of the rule of law in Brazil

The goal of this paper is to debate the degree of effectiveness of the rule of law in Brazil, through a survey measuring perceptions, attitudes and habits of Brazilians in regard to compliance to law. The survey conducted in Brazil is based on the study conducted by Tom R. Tyler in the United States, entitled Why People Obey the Law? (New Haven, CT: Yale University Press, 1990). The main argument of Tyler´s study is that people obey the law when they believe it’s legitimate, and not because they fear punishment. We test the same argument in Brazil, relying on five indicators: (i) behavior, which depicts the frequency with which respondents declared to have engaged in conducts in disobedience to the law; (ii) instrumentality, measuring perception of losses associated with the violation of the law, specially fear of punishment; (iii) morality, measuring perception of how much is right or wrong to engage in certain conducts in violation of the law; (iv) social control, which measures perception of social disapproval of certain types of behavior in violation of the law, and (v) legitimacy, which measures the perception of respect to the law and to some authorities. Results indicate that fear of sanctions is not the strongest drive in compliance to law, but more than legitimacy, indicators of morality and social control are the strongest in explaining why people obey the law in Brazil.

A new species of the Rhinella margaritifera group (Anura: Bufonidae) from Brazilian Pantanal

We describe adult morphology, advertisement call and some natural history traits of a new species of toad from the Pantanal, western Brazil. Rhinella paraguayensis sp. nov. belongs to the Rhinella margaritifera group, and is characterized by medium size, snout rounded in dorsal view, with a vertical apical ridge, supraorbital crests weakly developed, parietal crest not well developed, postorbital crest prominent, presence of a dorsolateral line of tubercles, tympanum evident, bony protrusions at angle of jaws, absence of vertebral apophyses and of projections on upper eyelids, and parotoid glands small. The new species is distinguished from other species of the group by geographic distribution and by the use of floating mats of vegetation as reproductive site.

Population dynamics and net primary production of the aquatic macrophite Nymphaea rudgeana C. F. Mey in a lotic environment of the Itanhaém River basin (SP, Brazil)

Neste trabalho, foi estudada a dinâmica populacional e estimada a produção primária líquida da macrófita aquática Nymphaea rudgeana em um braço do rio Itanhaém (Estado de São Paulo, Brasil). Esta espécie apresenta uma ampla variação anual de biomassa, em função da estação do ano, no local estudado. A partir do mês de novembro (13,1 g PS/m²), pode ser observado um aumento gradual da biomassa, atingindo o máximo em fevereiro (163,1 g PS/m²). Posteriormente, a biomassa diminui, mantendo-se em níveis baixos até um novo período de crescimento. A diminuição de biomassa está associada ao desenvolvimento de macrófitas flutuantes (Pistia stratiotes e Salvinia molesta) e, subseqüentemente, às condições ambientais desfavoráveis (valores de salinidade elevados) ao seu desenvolvimento. A produção primária líquida de N. rudgeana foi obtida a partir dos dados de biomassa e seu valor é estimado entre 3,02 e 3,82 t/ha/ano.

Cataract Remains an Important Cause of Blindness in Campinas, Brazil

Objective: To estimate the prevalence of blindness in the elderly population of Campinas, Brazil, and to describe the coverage and quality of cataract surgery services in the area. Methods: A brief assessment of cataract surgery services (using the RACSS (Rapid Assessment of Cataract Surgical Services Method) was conducted using random cluster sampling, with a sample composed of 60 clusters of 40 people aged 50 years or older. Visual acuity (VA) was measured and the lens status observed by direct visual ophthalmoscopy. From the selected sample of 2,400 subjects, 92.67% were examined. Results: Blindness (VA 3/60 with available correction) was found in 1.98 % (2.03 % among male subjects, and 1.94 % among female subjects). The prevalence of blindness varied with age, from 0.2%, in the group from 50 to 54 years, to 7.2% in those above 80. Cataract was the main cause of blindness (40.2%) followed by suspected posterior segment disorders (18.2%), diabetic retinopathy (15.9%), and glaucoma (11.4%). The cataract surgical coverage was of 93% (VA 3/60) and 82.18% when the criterion was VA 6/60 in the best eye. The main reasons the subjects did not receive surgical treatment were: fear of undergoing surgery, 11.1%; lack of awareness about the condition, 16.7%; waiting for maturity, 16.7%; and contraindication to surgery, 44.4%. Conclusion: Cataract is the major cause of blindness in Campinas. Education on eye diseases, their prevention and treatment must become part of the city's public healthcare policies.

Chewing in temporomandibular disorder patients: an exploratory study of an association with some psychological variables

Aims: To compare kinematic parameters (ie, amplitude, velocity, cycle frequency) of chewing and pain characteristics in a group of female myofascial temporomandibular disorder (TMD) patients with an age-matched control female group, and to study correlations between psychological variables and kinematic variables of chewing. Methods: Twenty-nine female participants were recruited. All participants were categorized according to the Research Diagnostic Criteria for TMD (RDC/TMD) into control (n = 14, mean age 28.9 years, SD 5.0 years) or TMD (n = 15, mean age 31.3 years, SD 10.7) groups. Jaw movements were recorded during free gum chewing and chewing standardized for timing. Patients completed the Depression, Anxiety, and Stress Scales (DASS-42), the Pain Catastrophizing Scale (PCS), the Fear of Pain Questionnaire-III (FPQ-III), and the Pain Self-Efficacy Questionnaire (PSEQ). Statistical analyses involved evaluation for group differences, and correlations between kinematic variables and psychological questionnaire scores (eg, depression, anxiety, stress) and pain intensity ratings. Results: Velocity and amplitude of standardized (but not free) chewing were significantly greater (P < .05) in the TMD group than the control group. There were significant (P < .05) positive correlations between pain intensity ratings and velocity and amplitude of standardized chewing but not free chewing. There were significant (P < .05) positive correlations between depression and jaw amplitude and stress and jaw velocity for standardized but not free chewing. Conclusion: This exploratory study has provided data suggesting that psychological factors, manifesting in depression and stress, play a role in influencing the association between pain and motor activity.

Violence against children and adolescents: awareness and attitudes of Brazilian dentists

Violence against children and adolescents, ranging from negligence to sexual abuse, is an imperative public health problem. The ill treatments are considered as nonaccidental traumas, actions or omissions against children, who suffer physical or emotional violence. The main perpetrators are fathers, mothers, guardians, family, friends or the children‘s primary caretaker. It is very important to identify abuse cases, because this allows proper medical and legal intervention. In Brazil, the law n. 8.069, of July 13, 1990, known as the ECA -Statute for Children and Adolescents (SCA), stipulates the obligation to report suspected or confirmed cases of ill treatment against a child or adolescent to the Guardianship Council of the respective locality. The health professionals play a crucial role with regard to identifying cases of violence, collecting information, making early diagnosis of suspect cases and reporting such cases to the authorities. The dentists can contribute significantly, as most injuries occur in the orofacial region. Bite marks, burns, bruising, among others, are easily identified during a dental consultation. The aim of this work was to verify the awareness and attitudes of Brazilian dentists concerning violence against children and adolescents. This research was approved by the Research Ethics Committee of the Faculty of Dentistry of Araraquara – São Paulo State University (FOAr – UNESP). Sixty-three dentists answered an open and closed questionnaire concerning their formation, knowledge, experience and attitudes towards ill-treated children and adolescents. Among other results, thirty-nine dentists (61.9%) affirmed to have the means to identify illtreatment cases, 13 (20.6%) reported having some experience on this matter, but only 8 reported the cases to the Council of Guardianship, as determined by Brazilian law. Twenty percent of the reasons presented for not notifying the Council were fear of reprisal, and 60.0% were uncertain concerning the ethical and legal implications. Physical violence was the most reported form of identified violence (76.9%), followed by negligence (38.5%). Among the 13 professionals that had experience with violence cases, in 10 cases the perpetrators were identified – in 70.0% of the cases, the parents were the originators of such violence. It was concluded that further formation and orientation are necessary, in order to prepare dentists to act correctly when, during their professional activities, they encounter cases of violence against children and adolescents.

Why medical schools are tolerant of unethical behavior

The exposure to unethical and unprofessional behavior is thought to play a major role in the declining empathy experienced by medical students during their training. We reflect on the reasons why medical schools are tolerant of unethical behavior of faculty. First, there are barriers to reporting unprofessional behavior within medical schools including fear of retaliation and lack of mechanisms to ensure anonymity. Second, deans and directors do not want to look for unethical behavior in their colleagues. Third, most of us have learned to take disrespectful circumstances in health care institutions for granted. Fourth, the accreditation of medical schools around the world does not usually cover the processes or outcomes associated with fostering ethical behavior in students. Several initiatives promise to change that picture.

Comparative analysis of the replication of bovine herpesvirus 1 (BHV1) and BHV5 in bovine derived-neuron-like cells

Members of the subfamily Alphaherpesvirinae use the epithelium of the upper respiratory and/or genital tract as preferential sites for primary replication. However, bovine herpesvirus 5 (BoHV5) is neurotropic and neuroinvasive and responsible for meningoencephalitis in cattle and in animal models. A related virus, BoHV1 has also been occasionally implicated in natural cases of neurological infection and disease in cattle. The aim of the present study was to assess the in vitro effects of BoHV1 and BoHV5 replication in neuron-like cells. Overall, cytopathic effects, consisting of floating rounded cells, giant cells and monolayer lysis, induced by both viruses at 48 h postinfection (p.i.) resulted in a loss of cell viability and high virus titres (r = 0.978). The BoHV1 Cooper strain produced the lowest titres in neuron-like cells, although viral DNA was detected in infected cells during all experiments. Virus replication in infected cells was demonstrated by immunocytochemistry, flow cytometry and qPCR assays. BoHV antigens were better visualized at 48 h p.i. and flow cytometry analysis showed that SV56/90 and Los Angeles antigens were present at higher levels. In spite of the fact that BoHV titres dropped at 48 h p.i, viral DNA remained detectable until 120 h p.i. Sensitive TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling) and annexin V assays were used to identify apoptosis. BoHV5 induced death in approximately 50 % of cells within 24 h p.i., similar to what has been observed for BoHV1 Los Angeles. Infection with the BoHV1 Cooper strain resulted in 26.37 % of cells being in the early stages of apoptosis; 63.69 % of infected cells were considered viable. Modulation of mitochondrial function, as measured by mitochondrial membrane depolarization, was synchronous with the virus replication cycle, cell viability and virus titres at 48 h p.i. Our results indicate that apoptosis plays an important role in preventing neuronal death and provides a bovine-derived in vitro system to study herpesvirus-neuron interactions.

DEVELOPMENTAL STATUS OF N-(3-CHLORO-4-METHYLPHENYL) ACETAMIDE AS A CANDIDATE BLACKBIRD/STARLING ROOST TOXICANT

Large winter roosts of blackbirds (Icteridae) and starlings (Sturnus vulgaris) often cause conflicts, both real and imagined, between the birds and local human popula- tions. These conflicts may range from objections to the noise and odor engendered by thousands or millions of birds, to fear of epidemic human and livestock diseases, and the possibility of economic losses from crop depredations. Many people believe the most direct way to combat these conflicts is to reduce local roosting populations by kill- ing the birds. In response to this perceived need for a roost toxicant, the U.S. Fish and Wildlife Service (FWS) developed PA-14, a surfactant which can be aerially applied to problem roosts for population reduction (Lefebvre and Seubert 1970). Successful use of this material, however, requires concurrent rainfall and low temperatures, conditions which may not occur sufficiently often to permit roost treatment at desired times or places. Because of this difficulty, and continued pressures from management person- nel and the agricultural community, the Service has continued its search for a safe, ef- fective roost toxicant usable without severe weather restrictions. One of the current candidate materials is N-(3-chloro-4-methylphenyl)acetamide (CAT, DRC-2698), a derivative of StarlicideR (DRC-1339). This compound was initially developed by S.A. Peoples of the University of California-Davis (Peoples et al. 1976). California researchers are still investigating the avicidal potential of CAT, mainly on baits and in wick perches, while FWS interest has centered thus far on its possible utility as an aerially applied roost treatment. This report is a summary of our investigations to date.

An Overview of Relevant Aspects on VIM of Spar and Monocolumn Platforms

Vortex-induced motions (VIM) of floating structures are very relevant for the design of mooring and riser systems. In the design phase, spar and monocolumn VIM behavior, as well as semisubmersible and tension leg platform flow-induced motions, is studied and evaluated. This paper provides a checklist of topics and evidence from a number of sources to justify the selection that should be considered when designing spars or monocolumn platforms regarding the VIM phenomenon. An overview of the influential aspects of the VIM is presented such as heading, external appendages of the hull, concomitant presence of waves and currents, motion suppressor, draft condition (immersed portion of the hull), and external damping due to the presence of risers. Previous works concerning the VIM studies on spar and monocolumn platforms are also addressed. Whenever possible, the results of experiments from diverse authors on this matter are presented and compared. [DOI: 10.1115/1.4003698]

The prevalence of falls and associated factors among the elderly according to ethnicity

The historical and cultural characteristics reflect the Brazilian population. Elderly blacks are disadvantaged in socio-economic and demographic, clinical, functional and psychosocial aspects, reducing their social autonomy and functional independence. The decline in functional status due to variables associated with age and ethnicity can contribute to disabling events, such as falls. Socio-demographic, clinical and functional aspects related to falls were analyzed; Mobility, functional status and cognition were measured, with a statistical significance of pd '' 0.05. The sample of 196 elderly people was 48.5% white, 28% brown, 23.5% black, with an average of 69.9 years. There was reduced mobility classified as a medium risk for falls in 60% (p<0.013) among the elderly. With reference to groups analyzed, there were significant differences between variables for family income (p < 0.029), the occurrence of falls (p < 0.006), fear of falls (p < 0.023) and near-falls (p < 0.000). Blacks fall more often (p < 0.03). Statistical significance was revealed between ethnicity and self-reported occurrence of falls, fear of falling and the occurrence of near-falls, functional limitation and medium risk falls due to reduced mobility, with increased frequency of falls for elderly blacks.
