Do Visual Cues Contribute to the Neural Estimate of Viewing Distance Used by the Oculomotor System?
Authors: Wei Min , DeAngelis Gregory C. , Angelaki Dora E.
Published: April 2018

Perceived shape and depth judgments that require knowledge of viewing distance are strongly influenced by both vergence angle and the pattern of vertical disparities across large visual fields. On the basis of this established contribution of visual cues to the neural estimate of viewing distance, we hypothesized that the oculomotor system would also make use of high-level visual cues to distance. To address this hypothesis, we investigated how compensatory eye movements during whole-body translation scale with viewing distance. Monkeys viewed large-field (85 × 68°) random-dot stereograms that were rear projected onto a fixed screen and simulated either a textured wall or pyramid at different viewing distances. In these stereograms, we independently manipulated vergence angle, horizontal and vertical disparity gradients, relative horizontal disparities, and textural cues to viewing distance. For comparison, random-dot patterns were also projected onto a moveable screen placed at different physical distances from the animal. Several cycles of left-right sinusoidal motion of the monkey at 5 Hz were interleaved with several cycles of motion in darkness, and the relationship between eye movement responses and viewing distance was quantified. As expected from previous work, the amplitude of compensatory eye movements depended strongly on vergence angle. Although visual cues to distance had a statistically significant effect on eye movements, these effects were ∼20-fold weaker than the effect of vergence angle. We conclude that sensory and motor systems do not share a common neural estimate of viewing distance and that the oculomotor system relies far less on visual cues than the perceptual system.

Published: April 2018

We developed a microelectroporation method for the transfer of genes into neurons in the cerebral cortex of adult rodents, both rats and mice. We selectively expressed either green-fluorescent protein (GFP) or a Ca2+-binding deficient calmodulin (CaM) mutant in the anterior cingulate cortex (ACC). In mice that expressed GFP, positive neuronal cell bodies were found specifically at the injection site in the ACC. Mice that expressed CaM12, a mutant CaM with two impaired Ca2+binding sites in the N-terminal lobe, exhibited significant changes in vocalization, locomotion, and sensory functions. Long-term potentiation and long-term depression, two major forms of central plasticity, were completely abolished by expression of CaM12. Mice that expressed CaM34, a mutant CaM with two impaired Ca2+binding sites in the C-terminal lobe, did not show any significant behavioral or electrophysiological alterations. These findings provide strong evidence that CaM is critical for bidirectional synaptic plasticity. This new method will be useful for investigating gene function in specific brain regions of freely moving animals. Furthermore, this approach also may facilitate gene therapy in adult human brains.
Synaptic Transport of Human Immunodeficiency Virus-Tat Protein Causes Neurotoxicity and Gliosis in Rat Brain

Published: April 2018

Neurodegeneration, synaptic alterations, and gliosis are prominent features of human immunodeficiency virus (HIV) encephalitis, but HIV encephalitis is distinct from other viral encephalitides because neurodegeneration occurs in uninfected neurons at anatomical sites that are often distant from the site of viral replication. The HIV protein Tat is both neurotoxic and proinflammatory; however, its contribution to HIV-related synaptic dysfunction remains unknown. To determine the consequences of continuous Tat production in brain, we genetically engineered rat C6 glioma cells to stably produce Tat and stereotaxically infused these cells into the rat striatum or hippocampus. We discovered that HIV-Tat protein could be transported along anatomical pathways from the dentate gyrus to the CA3/4 region and from the striatum to the substantia nigra, resulting in behavioral abnormalities, neurotoxicity, and reactive gliosis. This demonstrates a unique neuronal transport property of a viral protein and establishes a mechanism for neuroglial dysfunction at sites distant from that of viral replication. Tat may thus be an important participant in brain dysfunction in HIV dementia.
Cerebellar Loops with Motor Cortex and Prefrontal Cortex of a Nonhuman Primate
Authors: Kelly Roberta M. , Strick Peter L.
Published: April 2018

We used transneuronal transport of neurotropic viruses to examine the topographic organization of circuits linking the cerebellar cortex with the arm area of the primary motor cortex (M1) and with area 46 in dorsolateral prefrontal cortex of monkeys. Retrograde transneuronal transport of the CVS-11 (challenge virus strain 11) strain of rabies virus in cerebello-thalamocortical pathways revealed that the arm area of M1 receives input from Purkinje cells located primarily in lobules IV-VI of the cerebellar cortex. In contrast, transneuronal transport of rabies from area 46 revealed that it receives input from Purkinje cells located primarily in Crus II of the ansiform lobule. Thus, both M1 and area 46 are the targets of output from the cerebellar cortex. However, the output to each area of the cerebral cortex originates from Purkinje cells in different regions of the cerebellar cortex. Anterograde transneuronal transport of the H129 strain of herpes simplex virus type 1 (HSV1) revealed that neurons in the arm area of M1 project via the pons to granule cells primarily in lobules IV-VI, whereas neurons in area 46 project to granule cells primarily in Crus II. Together, the findings from rabies and HSV1 experiments indicate that the regions of the cerebellar cortex that receive input from M1 are the same as those that project to M1. Similarly, the regions of the cerebellar cortex that receive input from area 46 are the same as those that project to area 46. Thus, our observations suggest that multiple closed-loop circuits represent a fundamental architectural feature of cerebrocerebellar interactions.

Published: April 2018

The Arctic seas are in a period of transition as they adjust to stimuli from anthropogenic climate change. The acoustic response to this adjustment is of fundamental interest, as acoustics provide an important means for Arctic remote sensing, communication and navigation, and there are important biological implications for marine mammals and other organisms that use sound. The Canada Basin Acoustic Propagation Experiment (CANAPE) is an effort to study Arctic acoustics; this paper reports on ocean sound-speed measurements from a pilot study undertaken between 30 July and 16 August 2015. Moored and shipborne observations of temperature and salinity were made in the upper 600 m of the ocean, allowing analysis along isopycnals (surfaces of constant density) to separate sound-speed structure due to internal-wave-induced vertical displacements from those originating from density-compensated temperature and salinity variations termed spice. Frequency spectra and vertical covariance functions were used to describe the space/time scales of displacements and spice. Internal-wave frequency spectra show a spectral slope much lower than the Garrett-Munk model, with the energy level roughly 4% of the standard Garrett-Munk value. Frequency spectra of spice show a form similar to the internal-wave spectra but with a slightly steeper spectral slope, presumably due to the horizontal advection of the spice by internal-wave currents. The root mean square sound-speed fluctuations from internal waves were small with values less than 0.1 m s–1. Spicy sound-speed fluctuations were much stronger, particularly in the upper 100 m where a maximum of 0.25 m s–1 was observed. Both processes have vertical decorrelation lengths less than 100 m. The observed strong variations in vertical and horizontal sound-speed structure will have significant impacts on acoustic applications, especially in the realm of communications, navigation, and remote sensing.

Objective

Primary aldosteronism (PA) is the most common endocrine form of arterial hypertension. The German Conn’s Registry’s purpose is to improve treatment outcomes of PA. We assessed whether key clinical, biochemical and epidemiological characteristics of newly diagnosed PA cases have changed over time, potentially indicating a different screening and referral practice in Germany evolving from 2008 to 2016.

Design

The German Conn’s Registry is a multicenter database prospectively analyzing morbidity and long-term outcome of patients with PA.

Methods

Phenotypic changes between three year periods were calculated using Mann–Whitney U tests and Kruskal–Wallis tests for independent variables.

Results

Over three time periods from 2008 to 2016, we noted a relative decrease of unilateral PA cases (67 vs 43%). Significantly more females were diagnosed with PA (33 vs 43%). Median daily defined drug doses decreased (3.1 vs 2.0) in the presence of unchanged SBP (150 vs 150 mmHg), plasma aldosterone (199 vs 173 ng/L) and PRC (3.2 vs 3.2 U/L). Median ARR values decreased (70 vs 47 ng/U) and median potassium levels at diagnosis (3.5 vs 3.7 mmol/L) increased as the percentage of normokalemic patients (25 vs 41%), indicating milder forms of PA.

Conclusions

Our results are in accordance with an increased screening intensity for PA. We identified a trend toward diagnosing milder forms, increasingly more females and less unilateral cases of PA.
Estrogen receptor subtypes dictate the proliferative nature of the mammary gland

Published: April 2018

Estrogen induces proliferation of breast epithelial cells and is responsible for breast development at puberty. This tightly regulated control is lost in estrogen-receptor-positive (ER+) breast cancers, which comprise over 70% of all breast cancers. Currently, breast cancer diagnosis and treatment considers only the α isoform of ER; however, there is a second ER, ERβ. Whilst ERα mediates estrogen-driven proliferation of the normal breast in puberty and breast cancers, ERβ has been shown to exert an anti-proliferative effect on the normal breast. It is not known how the expression of each ER (alone or in combination) correlates with the ability of estrogen to induce proliferation in the breast. We assessed the levels of each ER in normal mouse mammary glands subdivided into proliferative and non-proliferative regions. ERα was most abundant in the proliferative regions of younger mice, with ERβ expressed most abundantly in old mice. We correlated this expression profile with function by showing that the ability of estrogen to induce proliferation was reduced in older mice. To show that the ER profile associated with breast cancer risk, we assessed ER expression in parous mice which are known to have a reduced risk of developing ERα breast cancer. ERα expression was significantly decreased yet co-localization analysis revealed ERβ expression increased with parity. Parous mice had less unopposed nuclear ERα expression and increased levels of ERβ. These changes suggest that the nuclear expression of ERs dictates the proliferative nature of the breast and may explain the decreased breast cancer risk with parity.

Abstract:

The effect of antihyperglycaemic (antidiabetic) treatment on the late diabetic complications is one of the most important research areas in clinical diabetology. The relationship between glycaemic control and late micro- and macrovascular complications was highlighted by the results of the DCCT (Diabetes Control and Complications Trial) with type 1 and by the UKPDS (United Kingdom Prospective Diabetes Study) with type 2 diabetic patients. In these studies, observational follow-up investigations were also performed after the close-out of the randomized phase of the trial. In addition to these landmark studies, other randomized, controlled efficacy trials were also performed with observational follow-up investigations resulting in the development of the concept of metabolic memory or metabolic legacy. In this article, the main results of the studies are summarized. Orv Hetil. 2018; 159(15): 575–582.

Real or bogus: Predicting susceptibility to phishing with economic experiments v1
Authors: Chen Yan , Yeckehzaare Iman , Zhang Ark
Published: April 2018

We present a lab-in-the-field experiment to demonstrate how individual behavior in the lab predicts their ability to identify phishing attempts. Using the business and finance staff members from a large public university in the U.S., we find that participants who are intolerant of risk, more curious, and less trusting commit significantly more errors when evaluating interfaces. We also replicate prior results on demographic correlates of phishing vunerability, including age, gender, and education level. Our results suggest that behavioral characteristics such as risk attitude intolerance to risk, curiosity, and trust can be used to predict individual ability to identify phishing interfaces.

The Psychotherapeutic Value of Tragic Catharsis
Authors: Ermolaeva M.V. , Lubovsky D.
Published: April 2018

The article analyzes the phenomenon of catharsis that occurs from the perception of the tragic in art. Based on the eudemonistic understanding of catharsis we trace the cultural and historical aspects of the problem and show that catharsis as an aesthetic and psychological phenomenon that emerged in antiquity in order to facilitate acceptance of the necessity of dying of Self for rebirth into a new life. Using the examples of expressionist paintings and their early origins (M. Grünewald, E. Munch, P. Picasso) we analyze catharsis that occurs in the process of the tragic artworks perception, showing its therapeutic value for the audience (accepting the inevitable and searching for meaning, struggling with despair, resisting chaos, evil, and destruction). We show that the tragic in art, including painting, creates an aesthetic space that penetrates the living space of the subject of artistic perception and creates the possibility of expanding the conceptual horizon and spiritual renewal.

Comparative Analysis of the Processes of Group Work in Psychological Training and Psychotherapeutic Groups
Authors: Molostova A.N.
Published: April 2018

The article presents an approach to the analysis of the functioning of psychological training group and therapy group. The following aspects of the functioning of the psychological group are considered: evolution of the problematics and evolution of the relationships. Evolution of the problematics refers to the movement in the field of the content of the problems on which participants focus. Evolution of the relationships signifies the deepening of the contact between the participants in the dynamics of the group’s development. The author analyzes how the balance between these two aspects changes depending on the approach to group psychological work. Both aspects are considered in the context of the development stages of a training or therapy group. As a result, differences in the balance between the evolution of the relationships and evolution of the problematics in two types of groups are formulated. In psychological training evolution of the relationships between participants has an auxiliary value while the evolution of the problematics dominates. In group therapy evolution of the relationships is a key process that provides therapeutic changes.

Published: April 2018

Este artigo teve como objetivo estudar a valorização de lodo de uma Estação de Tratamento de Esgoto (ETE) como fertilizante no cultivo de fumo e aveia. Foram realizados três tratamentos para cada cultura, sendo que o primeiro não utilizou fertilizante, o segundo utilizou como fertilizante o lodo de ETE e o terceiro recebeu adubo mineral. Foram acompanhados nas culturas parâmetros como desenvolvimento das plantas, aspectos sanitários, aspectos nutricionais e presença de metais. Os resultados demonstraram-se positivos com relação ao uso do lodo de ETE como fertilizante nas culturas testadas. Na cultura da aveia a utilização do lodo de ETE apresentou resultados semelhantes à adubação mineral nos aspectos de crescimento, desenvolvimento e produtividade. Em relação aos aspectos nutricionais da aveia, o maior teor de proteína total foi encontrado naquela sem adubação e o maior teor de fibra bruta foi na aveia com adubação mineral. A cultura não apresentou contaminação por coliformes e salmonela-tradicional. Na cultura do fumo, as plantas com adubação mineral e lodo de ETE apresentaram desenvolvimento semelhante, com plantas saudáveis, ao contrário das plantas sem adubação, que se desenvolveram de forma inferior, com menor crescimento das plantas. Desta forma, o lodo de ETE apresenta elevado potencial como fertilizante para as culturas de fumo e aveia.

A piscicultura é um dos segmentos da produção animal que mais cresce no cenário mundial; neste ramo a qualidade da água é preocupação constante, pois quando esta apresenta má qualidade causa problemas na produção e pouca lucratividade. Objetivou-se avaliar a qualidade da água com base em algumas variáveis limnológicas em viveiros de piscicultura de engorda de tambaqui (Colossoma macropomum) com abastecimento em disposição sequencial. Os resultados indicaram que o regime de chuvas e o manejo durante o ciclo de produção influenciaram os parâmetros avaliados. No universo temporal da pesquisa (ago./2013 a jul./2014), os valores de pH, amônia e nitrito estiveram de acordo com a resolução Conama 357/2005; a alcalinidade e temperatura estiveram dentro dos padrões indicados para piscicultura, o contrário para a maioria dos valores amostrados para o oxigênio dissolvido e fósforo total. Em ago./2013, mês dos menores índices pluviométricos na região, os viveiros apresentaram condutividade elétrica acima do estabelecido pela resolução Conama 357/2005; em out./2013 houve aumento expressivo da densidade da comunidade fitoplanctônica com florações pontuais, acarretando a menor transparência e oxigênio dissolvido em todos os viveiros. Os resultados indicam a necessidade de adoção sistemática de boas práticas de manejo a fim de melhorar a qualidade ambiental das criações, como também contribuir para a sustentabilidade da atividade aquícola.

Published: April 2018

Background: Obstetric ICUs have become an important part of any tertiary care obstetric hospital. There have been studies in different parts of the world including India to determine the clinical spectrum, management and outcome of the patients admitted to these units. There have been a few studies on the subject from our part of the country, so we tried to carry out the said study. Our objective was to study indications of admissions, the pattern of complications, interventions required, and the maternal and fetal /neonatal outcome of the patients admitted in an obstetric ICU of our hospital.Methods: A retrospective descriptive study carried out at Lalla Ded hospital Srinagar, a tertiary care hospital of north India, between January 2017 and June 2017.Results: Fifty patients among 4890 obstetric admissions required ICU care giving an admission rate of 1.02%. Most of the patients fell in the age group of 26-30years (52%) followed by 31-35 years (24%).The most frequent indication for admission to ICU was pregnancy induced hypertension related eclampsia and preeclampsia which constituted about 44% (n=22) of the admissions. Obstetric haemorrhage was a close second and accounted for 34% (n=17) of the admissions. Mean ICU stay was 2.5±1 days. Four patients died giving a maternal mortality rate of 8% in this ICU. There were eleven fetal and neonatal deaths excluding ectopic pregnancy giving a fetal /neonatal mortality rate of 22%.Conclusions: Obstetric ICUs have become an important part of any tertiary care obstetric hospital. Significant number of patients get admitted and treated in these ICUs. In our part of the world majority of ICU admissions are because of eclampsia/preeclampsia and obstetric haemorrhage. Although a large number of mothers and their neonates get benefitted by way of admission to ICUs, a significant proportion of these mothers and their neonates die. There is a lot of scope of improvement in maternal and perinatal mortality. In addition to the importance of setting up of state of the art obstetric ICUs, the need for supervision of pregnancies, institutional deliveries, early detection of complications and early referral cannot be overemphasized.

Published: April 2018

Background: Thrombocytopenia is a common haematological problem encountered during neonatal period, particularly in the sick, premature neonates admitted in the NICU, and usually indicate an underlying disease process. Thrombocytopenia may be considered as an important and early tool in diagnosis of septicaemia in neonates.Methods: It is a hospital based cross sectional study. A total 105 neonates with blood and/CSF culture positive sepsis and associated thrombocytopenia admitted in NICU. This study was conducted to find the prevalence of thrombocytopenia in neonates admitted in NICU with culture proven sepsis and to observe the outcome of thrombocytopenia and sepsis.Results: Out of 105 culture positive neonates K. pneumoniae 47/105 (44.8%) was the commonest micro-organism isolated, followed by Pseudomonas 26/105 (24.8%), E. coli 14/105 (13.3%), Staphylococcus 11/105 (10.5%), Candida 2/105 (1.9%) in decreasing order. Thrombocytopenia was present in 100/105 (95.2%). Among thrombocytopenic neonates 38/100 (38%), 36/100 (36%) and 26/100 (26%) having severe, moderate and mild thrombocytopenia respectively. 38 (38%) newborns of severe thrombocytopenia among them K. pneumoniae (50.0%) was commonest organism, followed by Pseudomonas. (23.7%) and Staphylococcus (15.8%) in the decreasing order. 36 (36%) newborns of moderate thrombocytopenia among them K. pneumoniae (47.2%) again commonest organism associated, followed by Pseudomonas. (25.0%), and E- coli (11.1%). In severe thrombocytopenic newborns both GI and pulmonary (60.50%) haemorrhage was the most common bleeding manifestation. Mortality rate (37.1%) was high in newborns having sepsis.Conclusions: Bacterial sepsis is significantly complicated by thrombocytopenia. Severe thrombocytopenia in a suspected case of bacterial sepsis might predict Klebsiella sepsis and hence it may be rational to start empirical antibiotics covering the same.

sektörünün, yirminci asrın ilk yarısından sonra dünyanın en değerli ve gelir
getirici sektörlerinden biri olması hasebiyle ülke politikalarında önemli bir
yeri vardır. Türkiye’nin turizm sektörü açısından hak ettiği yere gelebilmesi
için özellikle şehirsel mekânların, sahip olduğu değerleri cezbedici bir
şekilde hedef kitlelere sunmaları gerekir. İşte bu ahvalde zengin bir tarihsel
mirası, kültürü, stratejik konumu, sosyal dokusu ve dinamik ekonomisiyle
Malatya ili büyük bir turizm potansiyeline sahiptir. Malatya’nın sahip olduğu
değerlerin ortaya çıkartılması ve turizm açısından farkındalık oluşturacak bir
şehir konumuna getirilmesi amacı ile hem yerel halka hem de ziyaretçilere
yönelik bir anket çalışması yapılmıştır. Anket çalışmasına göre Malatya
denilince akla gelen en önemli iki özellik sırası ile kayısı ve gastronomi
olmuştur.
İhvân-I Safâ’nın Rivayetlere Yüklediği Anlam
Authors: ASLAN Recep
Published: April 2018

İhvân-ı Safâ, asırlara sâri ilkelerini, dört bölümden oluşan elli iki risâleye sığdırdıkları Resâilu İhvân-ı Safâ adlı eserde ortaya koymuşlardır. İhvân-ı Safâ Risâleler’i, gerek ülkemizde gerekse ülkemiz dışında farklı pek çok bilim dalında ciddi çalışmalara konu olmuştur; ancak bu risalelerde geçen hadisler hakkında müstakil herhangi bir çalışma kaleme alınmış değildir. Tesir bakımından İslam dünyasındaki pek çok kolektif hareketten geri kalmayan, yer yer birçoğundan daha kapsamlı etkileri olan bu söylem mensuplarına hadis bilim dalının ilgisiz kalması doğru olmayacağından, İhvân-ı Safâ-hadis ilişkisinin bu makalede ele alınmasında fayda mülahaza edilmiştir. Bu sebeple bu makalede İhvân-ı Safâ Risâleler’inde geçen rivayetlerin hangi amaçla kullanıldıklarını anlama gayreti içinde olduk. Yöntem olarak; İhvân-ı Safâ Risâleler’ini taramak suretiyle bunların ne tür rivâyetler kullandıklarını tespit edip, bu rivâyetlerin geçtiği kaynakları, rivâyetlerin sıhhat derecelerini ve bu rivâyetlere yükledikleri anlamları/yorumları incelemeye çalıştık.

“Medeniyetler ve Şehirler”
Authors: GÖKÇE Emrah Utku
Published: April 2018

Bu kitap
incelemesinin amacı, şehir ve medeniyet kavramları üzerine yeni bir bakış açısı
getiren Ahmet Davutoğlu’nun katkısını Medeniyetler ve Şehirler kitabı üzerinden
tahlil etmektir. Kitap incelenirken hem açıklayıcı hem de eleştirel yöntem
kullanılmıştır. Bu kitap, şehir yapılanmasının medeniyetler tarihi içindeki
rolü nedir ve şehir tarihte nesne midir, yoksa özne midir soruları üzerine inşa
edilmiştir. Kitabın sorulara cevabı ve aynı zamanda kitabın savı şöyledir:
şehir aslında tarihte sadece belirlenen ve şekillendirilen/dönüştürülen bir
nesne değil, aynı zamanda tarihin akışına etkide bulunan ve
şekillendiren/dönüştüren bir öznedir. Tarihin akışında belirleyici bir eksen
rolü oynayan ve bu akışın anlaşılmasında ve anlamlandırılmasında bizler için
yön gösterici bir pusula görevi gören bu şehirler, medeniyetlerin eksen
şehirleridir. Yazarın amacı, semai dinlerin en temel prensibi olan Tevhid
akidesi ve kadim düşüncenin (Çin, Hint, İran, Mezopotamya, Yunan) gelenekleri
ile bezenmiş medeniyet ve şehirlerin nasıl bir etkileşime girdiğini anlamak ve
anlamlandırmaktır.

Removal of Zinc from an Aqueous Solution Using Micellar-Enhanced Ultrafiltration (MEUF) with Surfactants
Authors: ŞAHİN TAŞ Deniz
Published: April 2018

In the present study, the optimum conditions have been investigated for the separation of Zn2+ ions from aqueous media by micellar enhanced ultrafiltration (MEUF). For this purpose, optimum conditions for the concentration of surface active agent in the feed solution (sodium dodecyl sulfate, SDS), cetyltrimethyl ammonium bromide (CTAB), triton-X-100 (TX100)), filtering pressure, stirring rate and for the membrane porosity have been determined. It is shown that the filtering pressure has a significant effect on the permeate flux but a relatively insignificant impact on rejection of Zn2+. Permeate flux increased linearly with increasing pressure, ranging from 0.32 mLmin-1m-2 at 3 bar to 0.72 mLmin-1m-2 at 4 bar. The results showed that by adding SDS anionic surfactant, the permeate flux and the removal efficiency of zinc increased. Best results in terms of zinc rejection coefficient is 97.5 % at 5.0 x 10-4 M zinc concentration, 1.0 x 10-2 M SDS concentration (~x 8 cmc), stirring rate 500 rpm and transmembrane pressure 4 bar.

Authors: Honorato Aurélia Regina de Souza
Published: April 2018

O texto que apresento fala de uma trajetória de pesquisa na busca de encontros com possibilidades de pesquisa em arte e em educação, que escapam dos tradicionais procedimentos metodológicos estabelecidos na academia. Uma trajetória que apresenta no percurso experiências com dispositivos inaugurais nos campos e que se consolidaram como alternativas na produção de conhecimento de pesquisa. Estes formatos metodológicos, que são abertos para múltiplas combinações, se mostraram potentes e abriram-se para acolher, nas pesquisas individuais e também nas coletivas do Grupo de Pesquisa em Arte, o que chamamos de Espaços do Possível. Espaços que buscam deslocar intencionalmente modos instituídos de se fazer pesquisa e conhecimentos em arte e em educação, ao aceitar e ressaltar categorias como incerteza, imaginação, ilusão, introspecção, visualização e dinamismo.Palavras-chave: Pesquisa, metodologia, arte, educação.

Proactive Versus Reactive Perpetrators: Aggression and Intimate Partner Violence
Authors: Lee Hyun-Soo , Cantos Arthur , Mach Jami , Wolff Jennifer
Published: April 2018

The relationship between proactive and reactive aggression could have significant implications for the conceptualization of intimate partner violence. In this study, victim statements found in police reports involving 299 unique adult male perpetrators were coded for proactive or reactive aggression content and analyzed in relation to existing measures of treatment outcomes. Family-only violent perpetrators were hypothesized to be rated as having used reactive aggression, and generally violent perpetrators were expected to have used proactive aggression. It was further predicted that proactive aggression would be more strongly associated with higher recidivism rates and lower intervention completion rates. Perpetrators were coded as 73.8% reactive and 26.2% proactive contrary to the assumptions of some sociocultural models of intimate partner violence, for example, the Duluth model. Chi square analysis was used to assess the relationship between type of aggression and typology. Reactive perpetrators who completed their intervention had significantly lower recidivism rates than reactive perpetrators who did not. Intervention completion was unrelated to recidivism rates for proactive perpetrators. In fact, no statistically significant difference was found between type of aggression and recidivism when controlling for intervention completion. Binary logistic regression was used to assess the relationship between type of aggression used, intervention completion, and recidivism with no significant associations found. These findings further clarify the relevance of reactive aggression in intimate partner violence perpetrators due to its relative frequency and potential intervention effects.
Attachment Security Priming and Domestic Violence: Augmenting Biopsychosocial Treatment of Perpetrators
Authors: Corvo Kenneth , Sonkin Daniel , Cooney Morgan
Published: April 2018

In spite of an inhospitable policy and funding environment for domestic violence perpetrator treatment, efforts in theory development and practice innovation have persisted. Among them are efforts to understand and treat domestic violence using attachment theory. General principles of attachment theory, as well as concepts more directly connected to violence between intimates and other family members, suggest approaches to working with perpetrators that show promise for emotional growth and behavioral change. One such approach is attachment security priming involving the clinical or experimental activation or evocation of secure attachment style through the use of various prompts or stimuli. Evidence supporting positive results from attachment security priming with potential for addressing domestic violence includes: diminished fear reactions, improved creative problem-solving, reduced psychological pain, persistence in managing uncomfortable feelings, more positive relationship expectations, less attachment anxiety, and modulation of threat-related amygdala reactivity.
Las Titulaciones De La Facultad De Educación De La Universidad De La Laguna, Un Análsis Desde La Perspetiva De Género

Throughout history, there have been periods in which education was restricted to women. This was seen through the generalization of public instruction (Moyano Law, 1857), when it began to require more women to educate their own sex. One of the significant effect it has was that education became a form of integration of women in the economic sphere and, therefore, outside the borders of reproductive life. It became one of the main career opportunities for women, who until then had been excluded from the professional world, becoming “their first massive professional occupation” (San Román, 1997). Historically, and currently, Early Childhood Education is a labor area occupied mainly by women. This fact has its origin in the numerous conditioning factors: historical, social, cultural, economic, and political. However, we started from the observation that the teaching profession has become a predominantly female activity. This paper focuses on analyzing different factors of feminization that allow us to understand the causes for which the studies of child teaching at the University of La Laguna were carried out mainly by women.
