Liver Metastasectomy and Systemic Therapy Improve Overall Survival Compared With Surgery Alone After Curative Liver Resection of Colorectal Metastases in a Developing Country (Costa Rica)
Authors: Quesada-Soto Paula , Landaverde Denis , Ramos-Esquivel Allan 
Published: May 2016

Background Resection of liver-isolated metastases of colorectal cancer (CRC) offers the greatest likelihood of cure. Nevertheless, recurrence rates after this procedure are high, and chemotherapy is a reasonable choice with inconclusive evidence. We aimed to determine if there is a survival difference between patients receiving systemic therapy with surgery versus surgery alone for resection of liver metastases. Methods From a source population of 170 patients treated in our National Centre (Centro Nacional de Cirugía Hepatobiliar, San José, Costa Rica), with liver metastases from various primary sites, we selected 51 patients with CRC who underwent hepatic resection with curative intent. We categorized patients according to the treatment received (fluoropyrimidine-based chemotherapy plus or minus monoclonal antibody and surgery v surgery alone) and then calculated the overall survival (OS) rate according to the Kaplan-Meier method. A Cox proportional hazard model was used to assess the influence of potential confounding variables on OS. Results After a median follow-up of 41.6 months, OS was significantly better for patients treated with systemic therapy (before and/or after hepatic resection) versus surgery alone (3-year OS: 66.7% v 41.7%; hazard ratio, 0.37; 95% CI, 0.15 to 0.91; log-rank test: P = .025). There were no differences among patients who underwent neoadjuvant (48.7%), perioperative (46.2%), and adjuvant therapy (5.1%). The use of systemic therapy was significantly associated with better OS after adjustment for confounding variables (hazard ratio, 0.23; 95% CI, 0.07 to 0.92; P = .03). Conclusion Our findings support the use of systemic therapy (either perioperative, neoadjuvant, or adjuvant) as part of isolated hepatic metastasectomy from CRC.
Robert Greene’s Ghosts
Authors: Fallon Samuel 
Published: May 2016

Abstract
After the popular Elizabethan writer Robert Greene died in 1592, a series of pamphlets appeared with stories of his ghost’s haunting returns. These pamphlets—Henry Chettle’s Kind-Harts Dreame (1592), Barnabe Riche’s Greenes Newes both from Heauen and Hell (1593), and John Dickenson’s Greene in Conceipt (1598)—played on the striking persona that Greene had fashioned for himself, premised on a mode of self-disclosure at odds with his romances’ fictional surfaces and crafted to remedy the impersonality of print circulation. The ghost pamphlets both appropriated and demystified the charisma of Greene’s persona, their acts of ventriloquism exposing the fiction behind his performance of sincerity. At the same time, they confronted the fictionality at the heart of public discourse itself—the imaginary presence that grounded the increasingly diffuse readerships of the early modern book trade.
The Heat Exchanger Performance of Shell and Multi Tube Helical Coil as a Heater through the Utilization of a Diesel Machine’s Exhaust Gas
Authors: Zainuddin . , Nurdin Jufrizal , Is Eswanto 
Published: May 2016

A review on reutilization of heat waste from a diesel machine is absolutely important. This is because the exhaust gas potential of a Diesel machine keeps increasing and not much has been utilized by the industry. One of the techniques of reutilizing the heat waste in industry is by using a heat exchanger. The technique is also very useful for the environment because it can reduce air pollution caused by the exhaust gas of the diesel machine. The main purpose of the research is to find out the capability of shell and multi-tube helical coil HE as an air heater by utilizing the exhaust gas of the Diesel machine. The heat exchanger of shell and multi-tube helical coil utilizes the exhaust thermal gas of the Diesel machine as the air heater already made. The apparatus has the following dimension: the shell length of 1.05 m, diameter 0.1524 m, tube length of 3.25 m with 20 coils, tube diameter of 0.011 m, coil diameter of 0.0508 m with 4 helical coils. The type of Diesel machine to use in the testing is 4FB1 Isuzu Diesel engine. The machine has the maximum machine power and rotation of 54 kW and 3,600 rpm. The performance testing of heat exchanger has been conducted in some variations of Diesel machine rotations of 1,500 rpm, 1,750 rpm, 2,000 rpm, 2,250 rpm and 2,500 rpm. The testing result shows a maximum effectiveness to happen at the machine rotation of 1,500 rpm. The maximum effectiveness to get is 67.8% and then it goes down drastically in accordance with the increase of air mass flow rate. The hot air temperature created is from 47.1°C to 52.3°C so that it can be used for the purpose of drying up the unhulled rice.
Rebalancing Competition Policy to Stimulate Innovation and Sustain Growth
Authors: Chan Jonathan , Fung Herbert 
Published: May 2016

Abstract
Innovation is fundamental to sustainable economic development because input resources are finite. When an economy faces constraints such as land and labour, innovation fuels continued growth through new technologies that utilises the limited resources more productively. Competition contributes to this process by providing a platform for new technologies to replace old ones, but excessive competition may also dampen the incentives to innovate. Unlike economics literature which typically examines how market structure affects innovation, this paper explores how innovation affects the market structure. We observe that, as innovative businesses are scalable, markets are becoming more concentrated from a static point of view. However, as disruptive innovation takes place in the broader ecosystem of separate but related markets, product life cycles shorten, and these concentrated markets become more competitive from a dynamic point of view. We also find that innovative products often do not conform to existing regulations. In order to unleash the full potential of innovation as a driving force for sustained economic growth, we recommend a rebalancing of competition law and policy towards stronger enforcement against lateral anti-competitive activities versus horizontal and vertical ones. We also recommend more emphasis on dynamic competition analysis versus static ones in regulatory decision-making.

Published: May 2016

Abstract
Diamond films were synthesized in a CH4-H2 system with good surface quality by adjusting the additive amount of argon and oxygen gas. The diamond phase content and surface roughness of samples are 86.1% and 81.5 nm, respectively. The results indicate that only Ar addition will decrease the purity of diamond films, whereas Ar-O2 mixed gas can further increase the diamond phase content. It is worth noting that the content of diamond phase has no significant increase when O2 flow exceed 1 sccm. The surface roughness reduced from 199.8 to 81.5 nm by the addition of 14 sccm Ar and 1 sccm O2, and the surface quality will be deteriorated in case of further increasing O2 or decreasing Ar concentration. Meanwhile, the growth rate under different conditions and the synergetic surface modification effect of Ar-O2 mixed gas for diamond films growth process were discussed.
Role Expectations in Public Digital Cultural Resources Integration Projects

Published: May 2016

AbstractA public digital cultural resources integration project involves the participation of multiple public cultural institutions, which must undertake different roles and accomplish the project’s missions through cooperation. In this study, we employed some concepts from the role expectation framework from role theory (including the designation and assignment of role expectations, and the designation and assignment of role functions), examined extant literature to obtain the roles of agents and their functions in a collaborative project, designed a role function system, and conducted interviews and a survey with workers in public cultural institutions. The results show that in China’s resources integration projects, there is stronger willingness for institutions to cooperate with institutions of similar administrative ranks; the institutions’ role expectations should be considered when assigning roles, and adequate roles should be given to each entity, with particular notice paid to mediation and coordination from third-party organizations; based on adequate role assignment, the role functions should be further detailed and elaborated at the start of the project.
Two approaches to defining internal, external, and zero-focalization
Authors: Stühring Jan , Köppe Tilmann 
Published: May 2016

AbstractThe paper discusses two approaches to defining internal, external, and zero-focalization. According to the first approach, the three types of focalization are defined in terms of a relation of a character’s knowledge to the narrator’s report. We argue that the definitions based on this approach are seriously flawed. According to the second approach, whether a narrative is internally, externally or zero-focalized depends on how the information that the reader gets about the fictional world is constrained. We discuss some ways of rendering these definitions more precise, and we point to a remaining problem of the definitions.
Senik, C. (2014): L'économie du bonheur. Paris: Seuil
Authors: Urteaga Eguzki 
Published: May 2016

La economista Claudia Senik acaba de publicar la obra L'économie du bonheur [La economía de la felicidad] en la editorial Seuil, cuya colección La République des Idées está codirigida por Pierre Rosanvallon e Ivan Jablonka. Conviene recordar que la autora es catedrática de Economía en la Universidad de París La Sorbona y en la Escuela de Economía de París, además de ser miembro del Instituto Universitario de Francia. Ha publicado numerosos artículos de referencia en revistas científicas de prestigio internacional tales como Journal of Economic Behavior and Organization, Oxford Review of Economic Policy, Review of Economics and Statistics, The Economic Journal y Journal of Comparative Economics. Es representante de la nueva generación de economistas galos, al igual que Thomas Piketty (2013), quienes debaten constantemente con los economistas anglosajones, dialogan con las demás ciencias sociales y compaginan reflexión teórica y trabajo empírico.La presente obra se interesa por el vínculo existente entre crecimiento económico y sensación de felicidad. Como lo constata la propia autora: "La modernidad democrática ha convertido la felicidad [...] en un principio constitucional, casi en un deber" (Senik, 2014, p. 7). Con el transcurso del tiempo, y especialmente a lo largo de los últimos quince años, la felicidad y su medida se han convertido en objetos legítimos de las ciencias económicas. De hecho, la economía de la felicidad encuentra su origen en la Escuela de Leyde (situada en Holanda) durante los años setenta del pasado siglo y se ha desarrollado especialmente a partir de los años noventa, gracias a la preocupación creciente de los investigadores por esta cuestión y a la disponibilidad de series estadísticas. Desde hace varias décadas, se mide el nivel de felicidad subjetiva declarada por los individuos a través de grandes encuestas internacionales.

Published: May 2016

Después de su primer libro Hay vida después de la crisis, Carlos Díez decide publicar esta nueva obra titulada La economía no da la felicidad, pero ayuda a conseguirla, con la que pretende que todo público pueda entender los conocimientos económicos que han regido desde siempre a la sociedad.El propósito fundamental del libro, menciona Carlos Díez, es "humanizar la economía para ponerla al servicio del hombre y no al revés" (p. 5); además, explica cómo afectan los diferentes sistemas políticos a la economía y al crecimiento económico: "Si queremos obtener una imagen fiel de la realidad, la economía no puede estudiarse aislada del análisis político y social" (p. 5).La economía es una ciencia viva para todos los individuos..., hacemos economía cuando decidimos qué comprar y cuánto comprar; hacemos economía cuando decidimos cómo gastar nuestro dinero y sacarle la mayor utilidad; pensamos en economía sin saberlo cuando vemos que los precios incrementan y nuestro poder adquisitivo es cada día menor. No obstante lo anterior, cuando escuchamos hablar de temas económicos, pensamos en algo complicado y difícil de entender.Con la presente obra el autor nos guía por las principales escuelas del pensamiento económico y sus aportaciones más destacadas. Afirma que las ideas mueven al mundo, así como resalta la importancia de volver a situar al hombre en el centro de las decisiones y que la globalización y evolución tecnológica deben ser instrumentos para mejorar nuestras vidas.El autor afirma que después de la gran crisis del 2008, y con base en los hechos registrados, se creó la enorme necesidad de concienciar a las personas e impulsarlas a adquirir el conocimiento que los ayude a tratar asuntos relacionados con la economía, con la finalidad de evitar desastres que obstruyan una vida saludable y "nuestra felicidad económica".

Direct and indirect trophic effects of predator depletion on basal trophic levels
Authors: Chen Huili , Hagerty Steven , Crotty Sinead M. , Bertness Mark D. 
Published: May 2016

AbstractHuman population growth and development have heavily degraded coastal ecosystems with cascading impacts across multiple trophic levels. Understanding both the direct and indirect trophic effects of human activities is important for coastal conservation. In New England, recreational overfishing has triggered a regional trophic cascade. Predator depletion releases the herbivorous purple marsh crab from consumer control and leads to overgrazing of marsh cordgrass and salt marsh die‐off. The direct and indirect trophic effects of predator depletion on basal trophic levels, however, are not understood. Using observational and experimental data, we examined the hypotheses that (1) direct trophic effects of predator depletion decrease meiofaunal abundance by releasing deposit feeding fiddler crabs from consumer control, and/or (2) indirect trophic effects of predator depletion increase meiofaunal abundance by releasing blue carbon via the erosion of centuries of accreted marsh peat. Experimental deposit feeder removal led to 23% higher meiofaunal density at die‐off than at healthy sites, while reciprocally transplanting sediment from die‐off and healthy sites revealed that carbon‐rich die‐off sediment increased meiofauna density by over 164%: six times stronger than direct trophic effects. Recovering sites had both carbon‐rich sediment and reduced deposit feeding leading to higher meiofauna densities than both die‐off and healthy sites. This suggests that consequences of the trophic downgrading of coastal habitats can be driven by both direct and indirect trophic mechanisms that may vary in direction and magnitude, making their elucidation dependent on experimental manipulations.
Identidad, igualdad y educación
Authors: Cerletti Alejandro 
Published: May 2016

<p>Nuestro mundo actual se nos presenta como “un” mundo, único y omnipresente: el mundo del capitalismo globalizado en el que todas las relaciones, en mayor o menor medida, se han mercantilizado y todo (productos o informaciones) puede llegar a cualquier rincón del planeta. La diversidad es asumida como un elemento más de la circulación de mercancías (comerciales o culturales) y completa un cuadro homogéneo en el que cada cosa tiene su lugar asignado. En este trabajo emplearemos algunos aportes de Alain Badiou para abordar esta cuestión, intentando mostrar su entramado constitutivo, y ofrecer algunas perspectivas alternativas. En especial nos interesará exhibir la posibilidad de pensar un mundo que dé lugar a todos los mundos posibles, y que no sea el mero sometimiento planetario a la expansión del capital ni la simple aceptación “tolerante” del “otro”. Esta concepción del vínculo entre los humanos será la base para repensar la cuestión educativa en el mundo de hoy.</p><p> </p>
Reflexiones sobre evaluación de la enseñanza del diseño gráfico en la universidad
Authors: García Pacheco Nancy Patricia 
Published: May 2016

<p>El objeto del texto es reflexionar sobre la práctica evaluativa. Para ello se aborda una experiencia con estudiantes universitarios del programa de diseño gráfico de la Universidad de Boyacá, donde se indaga acerca de la percepción que tienen sobre la evaluación. Es vital pensar en una cultura evaluativa que busque una verdadera calidad en la educación y que se articule con la innovación en las prácticas pedagógicas. Es prioritario dejar de lado las mediciones que no dan cuenta de los procesos cognitivos que desarrolla cada ser humano a partir de su propia experiencia de aprendizaje. En la presente investigación se encontró que para el diseño gráfico la evaluación es subjetiva, otorgándole el poder al maestro de generar argumentos desde su propia interpretación de una realidad visual, que puede diferir con la percepción y el significado que cada individuo le otorga a una imagen. Posteriormente se presentan algunas posturas de los docentes del programa acerca de este tema. El texto finaliza con algunas conclusiones que suscita dicha reflexión.</p><p> </p>

Authors: Aliaga Chávez Noél 
Published: May 2016

Objetivo: Evaluar la utilidad de la cirugía ambulatoria con anestesia local en pacientes con patología herniaria inguinal. Material y métodos: Se realizó un estudio descriptivo tipo serie de casos, entre abril de 1996 y marzo de 1999, en el Servicio de Cirugía de la Clínica Fiori. Se intervinieron 1,167 pacientes por patología de pared abdominal, de las cuales 432 correspondieron a pacientes intervenidos por patología herniaria inguinal, de ellos 372 fueron operados con anestesia local, los cuales fueron incluidos en el estudio. Las técnicas quirúrgicas empleadas fueron las de Bassini y McVay, con un tiempo operatorio promedio de 30 minutos y un control a los 3 días post-cirugía. Resultados: El 72.9% de la patología herniaria inguinal se presentó en los pacientes entre los 31 y 70 años de edad. Solo el 2.6% (10 pacientes) presentaron complicaciones post-operatorias, 6 con recidivas de hernia inguinal, 2 con infección de herida operatoria, 1 con seroma y 1 con hematoma, ninguno resultó ser de gravedad; y 97.4 % (362) no presentaron ninguna complicación. No hubo complicaciones anestésicas. Conclusiones: La hernioplastia inguinal con anestesia local es efectiva, segura y económica.(Rev Med Hered 2003; 14:158-162).
