Seeking compositionality in holistic proto-language without substructure – do counterexamples overwhelm the fractionation process?

In holistic theories of protolanguage, a vital step is the fractionation process where holistic utterances are broken down into segments, and segments associated with semantic components. One problem for this process may be the occurrence of counterexamples to any segment-meaning connection. The actual abundance of such counterexamples is a contentious issue \cite{smith06,taller07}. Here I present calculations of the prevalence of counterexamples in model languages.  It is found that counterexamples are indeed abundant, much more numerous than positive examples for any plausible holistic language.

Caçadores de renda: uma investigação sobre a teoria do rent seeking

Este trabalho apresenta uma investigação sobre a teoria do Rent Seeking. Define o conceito de caçar renda e esclarece a diferença entre caçar renda e transferir renda. Mostra que o comportamento caçador de renda é determindado pela lógica da ação coletiva. Esta dissertação ainda analisa os impactos de bem estar social provocados por este tipo de comportamento. A evolução do processo investigativo revelou que o estudo do tema passa necessariamente pela análise da escassez da oferta arbitrariamente estabelecida, seja através da criação e manutenção artificial de monopólios, seja por meio de restrições ao comércio internacional

A model of capital accumulation and rent-seeking

A simple model incorporating rent-seeking into the standard neoclassical model of capital accumulation is presented. It embodies the idea that the performance of an economy depends on the efficiency of its institutions. It is shown that welfare is positively affected by the institutional efficiency, although output is not necessarily so. It is also shown that an economy with a monopolistic rent-seeker performs better than one with a competitive rent-seeking industry.

O regime brasileiro de tributação de lucros auferidos por sociedades controladas e coligadas no exterior: uma visão do atual regime por meio da ótica da teoria do rent seeking

O presente trabalho tem por objetivo analisar, pela ótica da teoria do rent seeking, a evolução da legislação e da jurisprudência administrativa e judicial acerca do regime da tributação dos lucros, ganhos de capital e rendimentos auferidos por sociedades controladas e coligadas no exterior. Observar-se-á a hipótese da legislação e das suas diversas interpretações refletirem interesses predominantemente de apropriação de renda, tanto por parte da Administração Pública quanto dos agentes privados. Nesse sentido, após uma exposição da teoria do rent seeking e da sua relação com a teoria do patrimonialismo no Brasil, ela será aplicada no tema tributário proposto. Para tanto, verificar-se-á a evolução da legislação até o último diploma normativo relevante sobre o tema: a Medida Provisória nº 2.158-35/01. Neste momento, serão identificadas as principais controvérsias e os possíveis interesses nas diversas interpretações dadas às regras em questão, associando-os com os diversos problemas de rent seeking observáveis. A seguir, verificar-se-á, nas decisões do Superior Tribunal de Justiça (STJ), do Supremo Tribunal Federal (STF), e do Conselho Administrativo de Recursos Fiscais (CARF) qual a evolução do entendimento dos tribunais a respeito das referidas interpretações, verificando se algum consenso foi atingido e quais interesses estariam atingidos pelo rumo tomado pela jurisprudência sobre o tema. Neste contexto, a análise da evolução legislativa e jurisprudencial abordará os seguintes pontos controversos: (1) caracterização das regras brasileiras como CFC rules (característica antielisiva); (2) tributação de distribuição ficta ou de lucro da própria controladora ou coligada no Brasil; (3) constitucionalidade do artigo 43, parágrafo 2º, do Código Tributário Nacional, bem como do artigo 74 da Medida Provisória nº 2.158-35/01; e (4) a compatibilização com os Tratados contra a Dupla Tributação. Por fim, far-se-á uma conclusão, a partir dos resultados verificados, a respeito de como a evolução das regras tributárias em questão pode representar uma apropriação de renda sem benefícios públicos que pode favorecer indevidamente tanto o setor público como o privado.

Treatment seeking by individuals with obsessive-compulsive disorder from the British Psychiatric Morbidity Survey of 2000

Objective: For several reasons, many individuals with obsessive-compulsive disorder (OCD) do not seek treatment. However, data on treatment seeking from community samples are scant. This study analyzed service use by adults with OCD living in private households in Great Britain. Methods: Data from the British Survey of Psychiatric Morbidity of 2000, in which 8,580 individuals were surveyed, were analyzed. Service use was compared for those with OCD, with other neuroses, with different subtypes of OCD (only obsessions, only compulsions, or both), and with OCD and comorbid neuroses. Results: Persons with OCD (N=114) were more likely than persons with other neuroses (N=1,395) to be receiving treatment (40% compared with 23%, p<.001). However, those with OCD alone (N=38) were much less likely than those with OCD and a comorbid disorder to be in treatment (14% compared with 56%, p<.001). In the previous year, 9.4% of persons with OCD had seen a psychiatrist and 4.6% had seen a psychologist. Five percent were receiving cognitive-behavioral therapy, 2% were taking selective serotonin reuptake inhibitors, and 10% were taking tricyclics. Conclusions: Most persons with OCD were not in contact with a mental health professional, and apparently very few were receiving appropriate treatments. Very few persons with noncomorbid OCD were receiving treatment. Individuals with OCD who are in treatment may not be disclosing their obsessions and compulsions and may be discussing other emotional symptoms, leading to inappropriate treatment strategies. Public awareness of OCD symptoms should be raised, and primary care professionals should inquire about them with all patients who have depressive or anxiety disorders.

Obsessive-compulsive disorder: Prevalence, comorbidity, impact, and help-seeking in the British National Psychiatric Morbidity Survey of 2000

Objective: There is little information about obsessive-compulsive disorder in large representative community samples. The authors aimed to establish obsessive-compulsive disorder prevalence and its clinical typology among adults in private households in Great Britain and to obtain generalizable estimates of impairment and help-seeking.Method: Data from the British National Psychiatric Morbidity Survey of 2000, comprising 8,580 individuals, were analyzed using appropriate measurements. The study compared individuals with obsessive-compulsive disorder, individuals with other neurotic disorders, and a nonneurotic comparison group. ICD-10 diagnoses were derived from the Clinical Interview Schedule-Revised.Results: the authors identified 114 individuals (74 women, 40 men) with obsessive-compulsive disorder, with a weighted 1-month prevalence of 1.1%. Most individuals (55%) in the obsessive-compulsive group had obsessions only. Comorbidity occurred in 62% of these individuals, which was significantly greater than the group with other neuroses (10%). Co-occurring neuroses were depressive episode (37%), generalized anxiety disorder (31%), agoraphobia or panic disorder (22%), social phobia (17%), and specific phobia (15%). Alcohol dependence was present in 20% of participants, mainly men, and drug dependence was present in 13%. Obsessive-compulsive disorder, compared with other neurotic disorders, was associated with more marked social and occupational impairment. One-quarter of obsessive-compulsive disorder participants had previously attempted suicide. Individuals with pure and comorbid obsessive-compulsive disorder did not differ according to most indices of impairment, including suicidal behavior, but pure individuals were significantly less likely to have sought help (14% versus 56%).Conclusions: A rare yet severe mental disorder, obsessive-compulsive disorder is an atypical neurosis, of which the public health significance has been underestimated. Unmet need among individuals with pure obsessive-compulsive disorder is a cause for concern, requiring further investigation of barriers to care and interventions to encourage help-seeking.

Seeking one's heading through eye movements

A study of eye movements during simulated travel toward a grove of four stationary trees revealed that observers looked most at pairs of trees that converged or decelerated apart. Such pairs specify that one's direction of travel, called heading, is to the outside of the near member of the pair. Observers looked at these trees more than those that accelerated apart; such pairs do not offer trustworthy heading information. Observers also looked at gaps between trees less often when they converged or diverged apart, and heading can never be between such pairs. Heading responses were in accord with eye movements. In general, if observers responded accurately, they had looked at trees that converged or decelerated apart; if they were inaccurate, they had not. Results support the notion that observers seek out their heading through eye movements, saccading to and fixating on the most informative locations in the field of view.

Enhanced nicotine-seeking behavior following pre-exposure to repeated cocaine is accompanied by changes in BDNF in the nucleus accumbens of rats

We investigated the behavioral and molecular interactions between cocaine and nicotine, through evaluating locomotor activity, nicotine intravenous self-administration and gene expression. Locomotor sensitization was induced in male Wistar rats by repeated cocaine (20 mg/kg; i.p.) or saline injections once a day over 7 days. Three days after the last injection, rats were challenged with either saline or cocaine (15 mg/kg; i.p.) and the locomotor activity was measured. The very next day animals received either saline or nicotine (0.4 mg/kg; s.c.) and the locomotor cross-sensitization was tested. Animals were then prepared with intrajugular catheters for nicotine self-administration. Nicotine self-administration patterns were evaluated using fixed or progressive ratio schedules of reinforcement and a 24-h unlimited access binge. Immediately after the binge sessions animals were decapitated, the brains were removed and the nucleus accumbens was dissected. The dynorphin (DYN), μ-opioid receptor (mu opioid), neuropeptide Y (NPY), brain-derived neurotrophic factor (BDNF), tropomyosin-related tyrosine kinase B receptor (TrkB) and corticotropin- releasing factor receptor type 1 (CRF-R1) gene expression were measured by the reverse transcription-polymerase chain reaction (RT-PCR). Pretreatment with cocaine caused sensitization of cocaine motor response and locomotor cross-sensitization with nicotine. In the self-administration experiments repeated cocaine administration caused an increase in the nicotine break point and nicotine intake during a 24 h binge session. © 2013 Elsevier Inc.
