Parque do Flamengo: A construção cotidiana de um espaço democrático
Authors: Costa Lucia Maria De Sá Antunes
Published: August 2017

Este trabalho discute a imagem pública do parque do Flamengo, no Rio de Janeiro, enquanto espaço democrático. Parque do Flamengo é um dos maiores e mais populares parques urbanos da cidade, atraindo uma população diversificada em termos de grupos sociais, atividades e intenções de uso. Baseando-se numa estratégia de pesquisa que combinou métodos qual itativos e quantitativos, este estudo enfoca o parque enquanto paisagem cultural, e portanto sujeita a diferentes forças e aos interesses de diferentes grupos ao longo do tempo. A imagem do parque como um "espaço democrático" será discutida através das experiências cotidianas que as pessoas têm do parque, com um enfoque em alguns usos que nem sempre tem um caráter de recreação ou lazer: a apropriação e a transformação do parque em espaço religioso, de trabalho e de moradia; e a divisão social do parque. Este estudo mostra que a democratização do parque do Flamengo implica numa reinterpretação e reconstrução de sua paisagem pelos usuá­ rios, levando a uma segregação sócioespacial e inúmeros conflitos devido à multiplicidade de significados que são atribuídos ao parque. O trabalho conclui argumentando que uma das maneiras de se lidar com esta diversidade de valores seria através de uma participação mais ativa da comunidade local na administração de espaços públicos

Os projetos de paisagismo e os espaços livres dos edifícios de apartamentos
Authors: Sakata Francine Gramacho
Published: August 2017

Em 1972, a legislação de uso e ocupação do solo de São Paulo consagrou a implantação dos edifícios de apartamentos da forma como os conhecemos hoje: torres recuadas dos alinhamentos do lote e com grande porcentagem de área livre. Tal legislação prescreveu recuos obrigatórios e coeficientes de aproveitamento inversamente proporcionais às taxas de ocupação. Esta legislação aliada a outros fatores, como o trânsito e a escassez de áreas livres públicas geradas pelo crescimento da metrópole, levou as construtoras a utilizar o espaço livre como área de lazer devidamente equipada. A demanda por piscinas, quadras, playgrounds e jardins crescia e, assim, surgiram verdadeiros clubes particulares nos lotes dos edifícios. Muitos paisagistas trabalharam com este tipo de programa, e o estudo destes projetos ajuda a compor o quadro da arquitetura paisagística brasileira, a evolução de seus padrões do desenho. Alguns destes projetos fazem parte da pesquisa "Os espaços livres dos edifícios de apartamentos em São Paulo" desenvolvida com o apoio da Fapesp

Authors: Yamada Takumi , Yoshida Naoki , Itoh Taihei , Litovsky Silvio H. , Doppalapudi Harish , McElderry H. Thomas , Kay G. Neal
Published: August 2017

Backgrounds—

The parietal band is one of the muscle bands in the right ventricle. This study investigated the electrocardiographic and electrophysiological characteristics and ablation outcome of idiopathic ventricular arrhythmias (VAs) originating from the parietal band.

Methods and Results—

We studied 14 patients with idiopathic VA origins in the parietal band among 294 consecutive patients with VA origins in the right ventricle. The QRS morphologies of the parietal band VAs were characterized by a left bundle branch block and left inferior (n=12) or superior (n=2) axis pattern with the presence of a notch in the middle of the QRS in all cases, precordial transition at ≤lead V3 in 7 patients, and a slow QRS onset in 4 patients. During parietal band VAs, a far-field ventricular electrogram with an early activation was always recorded in the His bundle region, regardless of the location of the VA origins. During the catheter ablation, a mean number of 10.4±7.4 radiofrequency applications with a duration of 1099±1034 seconds were delivered. Catheter ablation was successful in 10 patients, and VAs recurred in 4 during a mean follow-up period of 41±24 months. A change in the QRS morphology was observed spontaneously in 4 patients, immediately after the ablation in 4, and at the time of a VA recurrence in 2.

Conclusions—

Idiopathic VAs rarely originated from the parietal band. The catheter ablation of the parietal band VAs was always challenging, requiring a large amount of the radiofrequency energy delivery for a successful ablation with a relatively high recurrence rate.
Discrepant Measurements of Maximal Left Ventricular Wall Thickness Between Cardiac Magnetic Resonance Imaging and Echocardiography in Patients With Hypertrophic Cardiomyopathy
Authors: Hindieh Waseem , Weissler-Snir Adaya , Hammer Helene , Adler Arnon , Rakowski Harry , Chan Raymond H.
Published: August 2017

Background—

We sought to compare maximal left ventricular (LV) wall thickness (WT) measurements as obtained by routine clinical practice between echocardiography and cardiac magnetic resonance (CMR) and document causes of discrepancy.

Methods and Results—

One-hundred and ninety-five patients with hypertrophic cardiomyopathy (median age, 52.8±15.1 years) who underwent echocardiography and CMR imaging within 6 months (median, 41 days; interquartile range, 16–97 days) were included. LVWT was assessed in parasternal long and short axis by 2-dimensional echocardiography and in short axis by CMR. By Bland–Altman plot, mean maximal LVWT difference between echocardiography and CMR was 0.5 mm (95% confidence interval, −6.9, 7.8) with equal distribution of discrepancy along the full range of LVWT. Ninety-seven patients (49.7%) were identified to have intermodal measurement discrepancies ≥10%. In 7 patients (7.2%), reported measurement by CMR was inaccurate because of interpretation error. In 90 patients (92.8%), echocardiography underestimated (n=32; 33.0%) or overestimated (n=58; 59.8%) maximal LVWT. Underestimation was because of focal LV hypertrophy (n=10; 10.3%) or poor acoustic windows (n=22; 22.7%) while overestimation resulted from inclusion of right ventricular myocardium (n=37; 38.1%), LV trabeculations (n=5; 5.2%), papillary muscle (n=3; 3.1%), and apical-septal bundle (n=1; 1.0%), as well as imaging plane obliquity (n=7; 12.5%). In 31 (15.9%) patients, measurement discrepancy occurred at diagnostic or prognostic cut-offs.

Conclusions—

Although maximal LVWT by echocardiography in general measured similar to CMR, discordance because of limitations in echocardiography technique was present in a significant subset of patients. As measurement of LVWT impacts diagnosis and sudden death management, CMR should be considered as part of routine evaluation of all patients with hypertrophic cardiomyopathy.
The (In)Compatibility of Appellate Mechanisms with Existing Instruments of the Investment Treaty Regime
Authors: Calamita N. Jansen
Published: August 2017

In its recent treaties, the European Union (EU) has established a new model of investor-State dispute settlement (ISDS). The EU’s new model entails the replacement of ad hoc arbitration with standing, treaty-based investment tribunals, staffed with judges appointed by the states parties. Awards produced by the EU’s new process will be subject to appellate review on issues of law and fact. The EU has indicated that it will pursue a treaty to multilateralize its new tribunal system. This article addresses the compatibility of the EU’s new ISDS model with existing instruments of the investment treaty regime: first, whether the introduction of an appellate mechanism or, indeed, the total reworking of ISDS to establish investment tribunals, renders instruments like the ICSID Convention and the New York Convention inapplicable to the modified process of ISDS; second, how the integration of any appellate mechanism with existing international investment treaties might technically be achieved.
The influence of amniotic membrane extracts on cell growth depends on the part of membrane and childbirth mode selected: a proof-of-concept study
Authors: Litwiniuk M. , Radowicka M. , Krejner A. , Grzela T.
Published: August 2017

Objective:

The amniotic membrane (AM) is a rich source of biologically active factors, important for wound healing and is widely used in various clinical applications, including tissue engineering, reconstructive surgery and wound management. The aim of the present proof-of-concept study was to assess the influence of amniotic membrane extracts on in vitro proliferation of main cells involved in tissue regeneration. The assessment was done in regards to the content of selected biologically active factors in amniotic membrane extracts.

Method:

The quantitative analysis of EGF, TGF-β and TIMP-1 in tested samples was assayed by enzyme-linked immunosorbent assay (ELISA) tests. The influence of amniotic membrane extracts on proliferation of keratinocytes (HaCaT), fibroblasts (Wi-38) and endothelial cell lines (HECa-10) was assessed using a colorimetric tetrazolium salt reduction assay.

Results:

In all of the amnion samples high amounts of EGF, TGF-β and TIMP-1 were detected. However, the content of these factors varied between placental and cervical portions of the same membrane. Moreover, various concentrations of biologically active factors between physiological at-term delivery and caesarean section-derived membranes were also observed. All of the assessed amnion extracts stimulated proliferation of HaCaT and Wi-38 cells, although samples prepared from caesarean section-derived cervical portion of amniotic membrane stimulated more proliferation of keratinocytes than of fibroblasts. In contrast to HaCaT and Wi-38 cells, proliferation of HECa-10 cell line was inhibited by all tested extracts.

Conclusion:

The results of our proof-of-concept study confirm that biological dressings prepared from amniotic membrane, especially its placental portion, since they stimulated both fibroblasts and keratinocytes, may provide relevant support for wound healing. On the other hand, dressings prepared from caesarean section-derived cervical portion of amniotic membrane, since they stimulate mainly epidermal cells, may be suitable for some specific applications, where more selective action is required, such as in ocular surgery. However, verification of this observation requires further studies.
Plantations versus the people: Explaining the diversity of land policies within the tropical British Empire
Authors: Byerlee Derek
Published: August 2017

Property rights regimes governing the expansion of agricultural commodity exports in the tropics have varied widely between and within colonial empires. This article illustrates this diversity within the British Empire from about 1850 to 1920. In British West Africa, indigenous customary rights were recognized and land concessions to plantations excluded. By contrast, colonial governments alienated large land tracts for plantations in Malaya, the Indian Hills and Ceylon that often conflicted with indigenous rights and shifting farming systems in upland forested areas. These differences among colonial policies on land and forest rights in turn led to quite different agrarian structures and strongly influenced the location of export production – differences that have persisted until today. The article explores a range of explanations for policy divergence with respect to land rights, including the initial conditions of population density and pre-existing industries, strategic concerns of the metropolitan power, growing civil society agitation on human rights in Africa, the role of individual champions of human rights and shifting paradigms within the empire with respect to the role of plantations.
The land question in early twentieth-century Portuguese legal colonial thought
Authors: Direito Bárbara
Published: August 2017

Part of a broader effort to bring the land question to the fore of scholarship about colonial Mozambique, this article looks at how legal colonial thought about land and property, part of the growing body of knowledge about topics of interest to the colonies, developed among Portuguese colonialists in the early twentieth century, especially with regard to African access to land. Different contributions to this thought will be analysed to enquire the role the land question played in the Portuguese colonial project in Africa. The main theories and debates about the land question held in Portugal will then be analysed alongside theories and debates about this same topic within an increasingly internationalized field of colonial thought, in which Portuguese colonialists also took part.
The Treaty of Versailles, the League of Nations and Portuguese overseas policy (1910–26)
Authors: Mendes Nuno Canas
Published: August 2017

The main goal of this article is to present the challenges for Portuguese colonial policy during the First Republic (1910–26), focusing on the international pressures against the survival of the Portuguese Empire. The article is divided into three parts: in the first we outline the state of the art regarding the questions to be raised. This is followed by an analysis of Portuguese colonial policy in the post-Versailles international context, particularly Afonso Costa’s negotiations for war reparations. In the third part, we examine particular aspects of the relationship between Portugal and the League of Nations in relation to colonial questions: namely, forced labour and the illicit trafficking of opium.
Evaluation and participation: Identifying different school organization profiles in Portuguese public schools
Authors: Veloso Luísa , Craveiro Daniela
Published: August 2017

The article discusses some of the major changes in Portuguese schools, due to both the external evaluation process set up in 2008 and the new school management model. The results discussed here demonstrate how the external evaluation process in Portugal highlights the importance of schools as organizations and the focus on community involvement in school management. A multivariate analysis based on a set of variables enabled us to define three school organization profiles (innovative, traditional and diffuse) using two points of reference: the type of curriculum offered and the relationship with the school community. The article consolidates an analysis based on mixed-method research, enhancing the analysis of qualitative information, how qualitative information can be turned into quantified variables, and how data reducing provides support for quantitative and qualitative data analysis.

Słowniki Bartłomieja z Bydgoszczy (1532 i 1544). Stan badań i perspektywy badawcze
Authors: Jankowiak Lucyna Agnieszka
Published: August 2017

The purpose of this article is to recall the 16th century Latin-Polish dictionaries by Bartholomew of Bydgoszcz. The article describes the figure of the monk, the history of his works as well as their structure and contents. The interest in the lexicons grew in the 70s of the 20th century when a manuscript dated 1532 (considered to be lost after the second world war) was found and a dictionary dated 1544 was unexpectedly discovered. A decision was made then to (jointly) publish both lexicons in the reversed version (Polish-Latin). This project still has not been completed which certainly has had its effect on the researchers’ weakening interest in the dictionaries and a small number of publications. Therefore the article presents possibilities of the analysis of the Polish and Latin lexical material.
Znaczenie i funkcja motywu klonu w warmińsko-mazurskich pieśniach ludowych
Authors: Lechocka Ewelina
Published: August 2017

This article is an analysis of maple motives, which occurred in collection of Warmian and Masurian folk songs elaborated in XIX and XX century. The purpose of this study was to define meaning and function botanic vocabulary mentioned in folkloristic texts and to compare poetic representation of maple motif with its role in every-day-life and culture of Warmia and Masuria’s inhabitants. As it was deducted from maintained analysis, the folk output and botanic themes are a valuable source of information about identity of rural population from Warmia and Masuria territories. Utilization of maple motif in folksongs is characteristic for its strong resemblance to empiric reality, in which the plant plays a great role in every-day-life and in immaterial culture.
Przywódca populistyczny i jego językowy obraz w aspekcie retoryki dominacji na podstawie wypowiedzi Pawła Kukiza. Perspektywa politologiczna i lingwistyczna
Authors: Kołodziejczak Małgorzata , Wrześniewska-Pietrzak Marta
Published: August 2017

The aim of this paper is characterizing one of the main populistic categories – the populistic leader. The problem was described from politological and linguistic point of view. The analyzed texts are Paweł Kukiz’ statements presented in the sessions of the Sejm (a lower chamber of the Polish parliament) and his Facebook posts. This paper presents the most important features which build the linguistic image of populistic leader. The authors claim that the image of populistic leader created in Paweł Kukiz’ texts is strictly combined with the dominance and its linguistic ways of expression, regarding the opposites to the people (citizens) and elites (political parties etc.). The cohesion of the described image of the populistic leader is created with the opposite we – they, which is ambiguous in the analyzed texts and enables Paweł Kukiz to construct different roles he plays in politics.

Graficzne i fonetyczne warianty techniczne w polskiej edycji Żywotów filozofów Mikuláša Konáča (F. Ungler, Kraków 1535)
Authors: Osiewicz Marek
Published: August 2017

The article attempts the technical determination of the graphic and phonetic variance acknowledged in the Polish edition of the Żywoty filozofów by Mikuláš Konáč. The method used was to analyze the distribution of oppositional graphic forms. It has been determined that the technical nature of the print is 9 variants: 4 graphic variants („j” = /j/ in position before consonant, „j” = /j/ in the voice-over position, „u” = /v/ i /v/ in the midpoint position, „th” = /t/) and 5 phonetic variants (miesce, miejsce, miejstce; wszystko; wieliki); among them are both regressive and progressive forms. The analysis also shows that, using the disclosed technical variants, zecer manipulated the graphical content of the lines in both possible ways: narrowing or widening.

García-Vaquero, MP, Ruiz-Pérez, I, Barbado, D, and Vera-Garcia, FJ. Electromyographic and kinematic analysis of the flexion-rotation trunk test. J Strength Cond Res 34(12): 3386–3394, 2020—Although most trunk endurance field protocols are performed in the sagittal or frontal planes, the flexion-rotation trunk (FRT) test combines trunk flexion with rotation, which may be relevant to rotation-related sports. The aim of this study was to describe the trunk and hip muscle activation and fatigue and the range of hip flexion of this test. Twenty-seven physically active males and females performed the FRT test after a period of practice. Electromyographic (EMG) signals were bilaterally collected from the rectus abdominis (RA), internal oblique (IO), and rectus femoris (RF), and hip flexion amplitude was measured using a biaxial electrogoniometer. Because the fast Fourier transform algorithm requires stationary EMG signals, subjects performed a 6-second isometric trunk flexion-rotation repetition just before and just after the test execution (preexecution and postexecution repetitions, respectively). Rectus abdominis showed the highest mean activation levels (approximately 30% maximal voluntary isometric contractions [MVC]) in the preexecution repetition, followed by IO (approximately 20% MVC). Also, the mean power frequency (MPF) significantly decreased from the pre-execution to the postexecution repetition for RA and IO, which shows abdominal muscle fatigue. Although each trunk flexion-rotation repetition involved an average 8–14° hip flexion, the RF activation was lower than 10% MVC, and no significant MPF reduction (i.e., no muscle fatigue) was observed for this muscle. In addition, significant negative correlations were found between the FRT test scores and the normalized EMG amplitudes of RF. Based on these results, the FRT test seems a valid field protocol to assess abdominal muscle endurance in trunk flexion-rotation exertions.

A Tale of Two Missions
Authors: Ryan Debora , Stokes-Rees Emily
Published: August 2017

This paper is an examination of the use of Native content in two contrasting sites, Sainte-Marie among the Hurons in Midland, Ontario, and Skä•noñh–Great Law of Peace Center in Syracuse, New York. These two sites share a common history, not only as early French settlements, but also as living history museums established in the twentieth century to memorialize and celebrate seventeenth-century Jesuit missions. Revisiting them today reveals their transformation into two very different museum models, incorporating very different methods of presenting indigenous knowledge. The authors consider how two distinct narratives have evolved in the twenty-first century, and how public memory continues to shape visitor expectations. The paper adds to the conversation about museums’ continuing incorporation of diverse historical narratives into their interpretation and programming as well as a rethinking of the ways in which we produce history for public consumption.
Variation in Recombination Rate and Its Genetic Determinism in Sheep Populations

Published: August 2017

Recombination is a complex biological process that results from a cascade of multiple events during meiosis. Understanding the genetic determinism of recombination can help to understand if and how these events are interacting. To tackle this question, we studied the patterns of recombination in sheep, using multiple approaches and data sets. We constructed male recombination maps in a dairy breed from the south of France (the Lacaune breed) at a fine scale by combining meiotic recombination rates from a large pedigree genotyped with a 50K SNP array and historical recombination rates from a sample of unrelated individuals genotyped with a 600K SNP array. This analysis revealed recombination patterns in sheep similar to other mammals but also genome regions that have likely been affected by directional and diversifying selection. We estimated the average recombination rate of Lacaune sheep at 1.5 cM/Mb, identified ∼50,000 crossover hotspots on the genome, and found a high correlation between historical and meiotic recombination rate estimates. A genome-wide association study revealed two major loci affecting interindividual variation in recombination rate in Lacaune, including the RNF212 and HEI10 genes and possibly two other loci of smaller effects including the KCNJ15 and FSHR genes. The comparison of these new results to those obtained previously in a distantly related population of domestic sheep (the Soay) revealed that Soay and Lacaune males have a very similar distribution of recombination along the genome. The two data sets were thus combined to create more precise male meiotic recombination maps in Sheep. However, despite their similar recombination maps, Soay and Lacaune males were found to exhibit different heritabilities and QTL effects for interindividual variation in genome-wide recombination rates. This highlights the robustness of recombination patterns to underlying variation in their genetic determinism.

The objective of this research was to highlight the economic importance of the optimal use of products and byproducts of oil palm. In Colombia, productive crops per hectare can generate, over one year, an average of 3.14 tons of oil, and up to 21.68 t of solid and liquid waste when the plant is on a productive stage. These data allowed the researcher to estimate that more than nine million of t of solid and liquid waste was produced from the 450 131 ha present in 2014, in Colombia; the produced biomass was used to generate energy and steam, releasing carbon dioxide back again into the environment. These residues have great potential in many industries, some to be developed, therefore, it is of special importance to try to maximize the use of waste produced by oil palm production, to generate economic and environmental benefits. An example of this is the palm kernel cake, with a nutritional potential in animal feed, fiber in the biocompound industry, biomass and stipe in the timber industry, glycerol, biodiesel, and liquid effluents in the chemical and biotechnological industry. The use of these raw materials may help to establish a positive balance in the cultivation of this species of oil palm in the country.
Reflecting the Sky in Water
Authors: Cristofaro Ilaria
Published: August 2017

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.
New ways to symmetrise free vibration equations of fluid–structure interaction systems

Published: August 2017

It can be difficult to use finite-element (FE) analyses to solve fluid–structure interaction due to asymmetric equivalent mass and stiffness matrices. Based on mathematical calculations, two new techniques are proposed to achieve a symmetric eigenvalue problem. For this purpose, new scale matrices to symmetrise the interaction system's eigenproblem are presented. Numerical FE analysis of a liquid-storage tank proves the validity and efficiency of the proposed techniques compared with other existing approaches, providing higher convergence rate and lower analysis time.

Authors: Луков Валерий Андреевич
Published: August 2017

 

Статья вводит в тематику третьего и четвертого номеров журнала «Горизонты гуманитарного знания», которая прежде всего акцентирует внимание на различных сторонах экологии культуры, но в особом направлении, а именно связывает экологию культуры не столько с сохранением культурного наследия, сколько с будущими состояниями общества. Название темы номеров «Горизонты будущего: аспект экологии культуры» отражает это понимание термина, который в определенном смысле превратился в концепт, т. е. в нем  совмещается логика с ценностной установкой, с образом, что и определяет его тезаурусную трактовку.

Relación entre la creatividad, la memoria inmediata y lógica en relación con el rendimiento académico en la Educación Secundaria
Authors: Ramos Moreno Ana María , López-Fernández Verónica , Llamas-Salguero Fátima
Published: August 2017

La presente investigación pretende analizar la relación entre creatividad y la memoria (inmediata y lógica), y a su vez éstas con el rendimiento académico en adolescentes de educación secundaria. La muestra estuvo compuesta por 51 estudiantes de 4º de educación secundaria de 15 a 16 años, en un colegio concertado en la Región de Murcia. El instrumento utilizado para evaluar la creatividad fue el test CREA, mientras que para evaluar la memoria lógica se utilizó el subtest 6, memorización lógica, Luria-DNA; y para evaluar la memoria inmediata fue subtest 5, memoria inmediata de Luria-DNA. El rendimiento académico se obtuvo a través de las notas de las diferentes asignaturas. Para conocer la relación entre las variables se calculó la correlación de Pearson y se hizo un análisis descriptivo a fin de establecer la media, la desviación, el máximo y el mínimo de cada variable. Los resultados indicaron que solamente existía una correlación significativa entre memoria inmediata y rendimiento académico, mientras que entre las demás no hubo relación significativa. Finalmente, se discuten los resultados encontrados y se proponen nuevas líneas de investigación.
Habilidades de liderazgo para una cultura de innovación en la gerencia de las universidades del distrito de Santa Marta
Authors: Issa Fontalvo Sugey Martha
Published: August 2017

Este artículo es producto de una investigación cuyo propósito fundamental fue analizar las habilidades del liderazgo para una cultura de innovación en la gerencia de las universidades del Distrito de Santa Marta. Para ello se estudiaron las bases teóricas de Horth y Buchner; Hargreaves y Fink; Argyris; Drucker y Rodríguez. La metodología utilizada fue el paradigma de investigación positivista, no experimental, transeccional, descriptiva y de campo. La población finita estuvo constituida por 37 empleados. Como instrumento para la recolección de datos se elaboró un cuestionario utilizando categorías de respuestas tipo Likert de 18 ítems, validado por siete expertos en el área. La confiabilidad del instrumento fue de 0.96, determinada con el método Alfa de Cronbach. Los resultados indican la ausencia de habilidades del liderazgo. Asimismo, se concluye que la gerencia no posee capacidad para percibir aspectos y hechos relevantes, carece del manejo reflexivo de situaciones complejas, además de presentar problemas de comunicación. Finalmente, se recomienda elaborar talleres o cursos de formación sobre habilidades para lograr un cambio en el comportamiento en pos de un pensamiento estratégico innovador.
Cargo por confiabilidad: ¿éxito o fracaso?
Authors: Ospina Riaño Andrés David , Mosquera Palacios Diewiskey
Published: August 2017

Con el objetivo de garantizar la confiabilidad en el suministro de energía eléctrica para el país, la Comisión de Regulación de Energía y Gas (CREG) diseñó, en el año 2006, el esquema del cargo por confiabilidad. Dicho esquema está compuesto por: (i) una remuneración que se paga por la disponibilidad futura de los activos de generación que requiere el país, y que pretende garantizar la entrega de la energía comprometida por los beneficiarios del cargo, previa asignación de una serie de cantidades de energía para entregar a futuro por estos, a través de un mecanismo de subasta, y (ii) un precio de escasez que establece la autoridad regulatoria, y que activa la exigibilidad de las obligaciones de energía comprometidas, cuando el precio de la energía en la bolsa supera el citado precio de escasez.Este mecanismo de remuneración de obligaciones futuras de entrega de energía ha viabilizado la inversión en los recursos de generación que requiere el país, para garantizar de manera eficiente la atención de la demanda de energía en condiciones críticas de abastecimiento, brindando señales económicas de inversión a largo plazo y permitiendo la estabilización de los ingresos de los generadores beneficiarios del cargo.No obstante los citados beneficios, y con ocasión del fenómeno de El Niño que ha afectado al país y de algunas situaciones de presunto incumplimiento en la entrega de las obligaciones de energía firme a cargo de un número reducido de beneficiarios del  cargo6, han surgido voces críticas en relación con el esquema del cargo por confiabilidad, que obligan a la comunidad jurídica a analizar la situación por la que atraviesa el Mercado de Energía Mayorista colombiano (MEM), así como la eficiencia del mecanismo diseñado por el regulador.Principalmente, surge una serie de inquietudes que pueden resumirse en cuatro básicas, que serán desarrolladas en el presente documento, así: (i) cuál es la naturaleza jurídica y económica del cargo por confiabilidad, (ii) si dicha herramienta genera obligaciones de disponibilidad para los agentes que reciben asignaciones de obligaciones de energía firme, (iii) si el diseño estructural de la metodología del cargo por confiabilidad debe ser revisado y por qué y (iv) qué soluciones podrían plantearse desde lo jurídico, no solo para mejorar la estructura de la metodología bajo análisis, sino para atender de manera integral la crítica situación por la que atraviesa el Sistema Interconectado Nacional (SIN).
Conceptualization of Parenting Stress in the Context of EMDR Therapy
Authors: De Vries Sander J. A. , Kuiper Chris H. Z.
Published: August 2017

Shapiro’s adaptive information processing (AIP) model hypothesizes that chronic parenting stress may result from past distressing parental experiences that were not adaptively processed. Our correlational study conducted a preliminary test of the AIP model to determine if current levels of parenting stress were associated with the number of reported distressing parental experiences. Thirty-five parents, whose children were being treated in a community clinic, were interviewed to identify memories of events related to the onset and aggravation of parenting stress. Standardized measure of present parenting stress was obtained. Regression analysis indicated that the number of reported unprocessed parenting experiences was a strong predictor for the level of parenting stress. The results support the AIP conceptualization of parenting stress and are discussed in the context of the development of an eye movement desensitization and reprocessing (EMDR) intervention to reduce parenting stress.
“Winter Is Coming!”—Treatment of Obsessive-Compulsive Disorder Imagery After Viewing the Television Series Game of Thrones
Authors: Potik David
Published: August 2017

This article presents the detailed case of a 27-year-old man who began to suffer from intrusive imagery after watching a brutal scene in the TV series Game of Thrones. The content of the intrusive imagery included images of people with enucleated eyes and was initially accompanied by anxiety about sharp objects. The patient’s mental distress was assessed by the Yale-Brown Obsessive Compulsive Scale and the Impact of Event Scale—Revised, and the patient was diagnosed with obsessive-compulsive disorder (OCD). Eye movement desensitization and reprocessing (EMDR) therapy was provided to treat related distressing memories and the intrusive imagery. As treatment progressed, more complex and layered aspects of the symptom presentation became evident, and EMDR was integrated with other treatments. These included psychodynamic psychotherapy to address his complicated relationship with his father, exposure and response prevention (ERP) therapy to reduce avoidance of sharp objects, and cognitive therapy (CT) for aggressive violent thoughts toward others. The article identifies the various clinical decision points and discusses theoretical conceptualizations and related factors. This clinical case report provides additional support for the body of knowledge on the relationship between traumatic events and imagery in OCD. Therefore, trauma-focused treatments, such as EMDR therapy, which concentrates specifically on those experiences, might be especially effective.
