Risk in General Equilibrium: Temporality and Performativity in the Ontology of Finance
Authors: Boldyrev Ivan 
Published: September 2016

Abstract
This paper reconstructs the ontology of finance as it is presented in Kenneth Arrow’s general equilibrium model of contingent commodities. The fundamental notion of modern finance, ‘Arrow securities’ (paying one monetary unit contingent upon a certain future event and nothing otherwise) is considered an elementary Luhmannian code of the economic. The performative, self-implementing tendencies in general equilibrium analysis are reinterpreted in view of the joint risk design as conceived by Dirk Baecker. Creating new (markets for) risks to control the future can be, on the one hand, traced back/justified with reference to Arrow’s world of contingent commodities and, on the other, rationalized as a way of adjusting the economic system and moving reality closer to its theoretical portrayal. I also associate the creation of the new ‘risk structures’ with the new overarching temporality inviting us to tame uncertainty and govern the future.
Der Hiatus – zur Spiegelbildlichkeit der Forschungsprogramme Latours und Luhmanns
Authors: Vogd Werner 
Published: September 2016

ZusammenfassungIn seinem Spätwerk „Enquête sur les modes d’existence“ bricht Bruno Latour mit der actor network theory bzw. erweitert diese in Richtung einer Theorie unterschiedlicher Sinn- bzw. Wertsphären, die auf den ersten Blick der von Luhmann entwickelten Theorie der funktionalen Differenzierung zu ähneln scheint. Dieser Beitrag stellt die Frage nach dem Verhältnis der beiden Theorieprogramme. Zunächst wird deutlich, dass zwei unterschiedliche Ausgangspunkte genommen werden. Latour beginnt beim Realismus naturalisierter Netzwerke, Luhmann bei der Reflexivität von Sinnprozessen. Wie auch immer, beide landen bei dem gleichen Bezugsproblem – der konditionierten Koproduktion –, das sie zur Erweiterung der Theorieanlage zwingt. Der von Latour mit den ‚Existenzweisen‘ entwickelte Lösungsversuch wird ausführlich vorgestellt. Am Beispiel der Felder ‚Religion‘ und ‚Wirtschaft‘ wird aufgezeigt, welche Einsichten hierdurch möglich werden. Latours und Luhmanns Zugänge erscheinen gewissermaßen spiegelbildlich, was sich nicht zuletzt auch in der unterschiedlichen Pointierung der Rolle des soziologischen Beobachters zeigt.
Concepts in multimodal discourse analysis with examples from video conferencing
Authors: Norris Sigrid 
Published: September 2016

AbstractThis article presents theoretical concepts and methodological tools from multimodal (inter)action analysis that allow the reader to gain new insight into the study of discourse and interaction. The data for this article comes from a video ethnographic study (with emphasis on the video data) of 17 New Zealand families (inter)acting with family members via skype or facetime across the globe. In all, 84 social actors participated in the study, ranging in age from infant to 84 years old. The analysis part of the project, with data collected between December 2014 and December 2015, is ongoing. The data presented here was collected in December 2014 and has gone through various stages of analysis, ranging from general, intermediate to micro analysis.Using the various methodological tools and emphasising the notion of mediation, the article demonstrates how a New Zealand participant first pays focused attention to his engagement in the research project. He then performs a semantic/pragmatic means, indicating a shift in his focused attention. Here, it is demonstrated that a new focus builds up incrementally: As the participant begins to focus on the skype (inter)action with his sister and nieces, modal density increases and he establishes an emotive closeness. At this point, the technology that mediates the interaction is only a mundane aspect, taken for granted by the participants.
Magic and Maledictions: Zechariah 5,1–4 in its ancient Near Eastern Context
Authors: Cranz Isabel 
Published: September 2016

AbstractFor almost a century biblical scholars have commented on the magical nature of Zechariah’s curse vision (Zechariah 5,1–4). In this vision, the prophet witnesses a flying scroll which represents a curse pronounced by God (Zech 5,1–4). Recent insights concerning the rationale of magic and the function of curses allow us to take a new look at this vision and evaluate how the prophetic author matched the elements of writing and speech to create a sense of magic. For this purpose, Zechariah 5,1–4 will be read against the backdrop of ancient Near Eastern, Levantine and biblical curse traditions. This paper shows how the prophetic author drew on curse traditions of the past to shape his ideas about God’s role in an ideal future in which the wicked would become subject to divine punishment.
Evolution of Mutation Rates in Rapidly Adapting Asexual Populations
Authors: Good Benjamin H , Desai Michael M 
Published: September 2016

AbstractMutator and antimutator alleles often arise and spread in both natural microbial populations and laboratory evolution experiments. The evolutionary dynamics of these mutation rate modifiers are determined by indirect selection on linked beneficial and deleterious mutations. These indirect selection pressures have been the focus of much earlier theoretical and empirical work, but we still have a limited analytical understanding of how the interplay between hitchhiking and deleterious load influences the fates of modifier alleles. Our understanding is particularly limited when clonal interference is common, which is the regime of primary interest in laboratory microbial evolution experiments. Here, we calculate the fixation probability of a mutator or antimutator allele in a rapidly adapting asexual population, and we show how this quantity depends on the population size, the beneficial and deleterious mutation rates, and the strength of a typical driver mutation. In the absence of deleterious mutations, we find that clonal interference enhances the fixation probability of mutators, even as they provide a diminishing benefit to the overall rate of adaptation. When deleterious mutations are included, natural selection pushes the population toward a stable mutation rate that can be suboptimal for the adaptation of the population as a whole. The approach to this stable mutation rate is not necessarily monotonic: even in the absence of epistasis, selection can favor mutator and antimutator alleles that “overshoot” the stable mutation rate by substantial amounts.

OBJECTIVE:
To assess if exposure to repeat dose(s) of antenatal corticosteroids has beneficial effects on neurodevelopment and general health in mid-childhood, at 6 to 8 years’ corrected age.

METHODS:
Women at risk for very preterm birth, who had received a course of corticosteroids ≥7 days previously, were randomized to intramuscular betamethasone (11.4 mg Celestone Chronodose) or saline placebo, repeated weekly if risk of very preterm birth remained. Mid-childhood assessments included neurocognitive function, behavior, growth, lung function, blood pressure, health-related quality of life, and health service utilization. The primary outcome was survival free of neurosensory disability.

RESULTS:
Of the 1059 eligible long-term survivors, 963 (91%) were included in the primary outcome; 479 (91%) in the repeat corticosteroid group and 484 (91%) in the placebo group. The rate of survival free of neurosensory disability was similar in both groups (78.3% repeat versus 77.3% placebo; risk ratio 1.00, 95% confidence interval, 0.94–1.08). Neurodevelopment, including cognitive function, and behavior, body size, blood pressure, spirometry, and health-related quality of life were similar in both groups, as was the use of health services.

CONCLUSIONS:
Treatment with repeat dose(s) of antenatal corticosteroids was associated with neither benefit nor harm in mid-childhood. Our finding of long-term safety supports the use of repeat dose(s) of antenatal corticosteroids, in view of the related neonatal benefits. For women at risk for preterm birth before 32 weeks’ gestation, ≥7 days after an initial course of antenatal corticosteroids, clinicians could consider using a single injection of betamethasone, repeated weekly if risk remains.
La medición de la eficiencia y la productividad. Antonio Álvarez Pinilla (Coordinador). Madrid: Editorial Pirámide. 2013.
Authors: Becerra Peña Diana Lizette 
Published: September 2016

A través de la obra La medición de la eficiencia y la productividad, financiada por el Banco Mundial y el Instituto de Estudios Fiscales, se pretende acercar al lectora las cuestiones de la estimación de la productividad y la eficiencia.La selección de este material se hace con base en el creciente interés por evaluar los niveles de producción ante un entorno de recursos limitados. Si bien la eficiencia lleva implícita la idea de conseguir la mayor productividad posible, ambos elementos no son sinónimos; la productividad está determinada por la relación que existe entre los insumos utilizados y la cantidad de productos resultantes, mientras que la eficiencia describe cómo es la relación manifestada entre un nivel de producción observado y el nivel ideal de esta, con lo que destaca la importancia que tiene ahondar en el tema para una mejor comprensión.El libro es resultado del trabajo coordinado por el profesor Antonio M. Álvarez Pinilla, aunado a los esfuerzos de un grupo conformado por veintiún investigadores en las áreas de economía, estadística, econometría, negocios y administración, provenientes principalmente del Departamento de Economía de la Universidad de Oviedo, así como de otras universidades españolas y extranjeras, donde la elección de los colaboradores se ha hecho con base en el prestigio que se tiene sobre la temática, de manera que se ofrezca al lector una obra con aportaciones enriquecedoras.
La lógica y la trama de las cosas
Authors: Moretti Alberto 
Published: September 2016

Se examinan algunas versiones representativas de las tesis contrarias a la relación entre las estructuras del discurso y de la realidad. Se propone distinguir entre los aspectos constitutivos y no constitutivos del lenguaje y de la realidad, manifiestos en la lógica de un lenguaje común. Se sostiene que los primeros son mínimos y que las teorías lógicas específicas han de considerarse partes de teorías generales sobre el mundo, parcialmente normativas, empíricamente discutibles e históricamente cam-biantes. En consecuencia, no hay motivos para creer que exista un dominio universal de objetos o de propiedades y, correlativamente, una única estructura del mundo, una sola concepción aceptable o completa de este, o una única lógica universal aceptable.

Published: September 2016

By-products valorization in bio-fuels industry is an important issue for making the global process more efficient, more profitable and closer to the concept of biorefinery. Fusel oil is a by-product of bioethanol production that can be considered as an inexpensive and renewable raw material for manufacturing value-added products. In this work, results in terms of composition and physicochemical properties of six samples of fusel oil from industrial alcohol facilities are presented. Composition of the main components was established by gas chromatography. Complementary techniques, such as headspace solid-phase microextraction and gas chromatography–mass spectrometry (GC-MS), were used for detection of minor components. Fifty-five compounds were identified. Physicochemical properties such as density, acid value, moisture content and true boiling point curves were determined. Results are useful in the conceptual design of separation strategies for recovering higher alcohols, as well as to consider new options of valorization alternatives for fusel oil.
Method for the multi-criteria optimization of car wheel suspension mechanisms
Authors: Alexandru Catalin , Totu Vlad 
Published: September 2016

The paper deals with a general method for the multi-criteria optimization of the rear wheels suspension mechanisms in terms of kinematic behavior. The suspension mechanism is decomposed in basic binary links, and the kinematic synthesis is separately performed for each of them. The design variables are the global coordinates of the joint locations on the car body (chassis). The disposing of the joints on the wheel carrier were exclusively established by constructive criteria. The design objectives relate to kinematic position parameters of the wheel (displacements of the wheel centre along longitudinal and transversal directions, and modifications of the wheel axis direction), the optimization goal being to minimize these variations during the wheel travel. A computer program for the kinematic study was developed in C++. The application was performed for the wheel suspension mechanism of a race car.
Optimal under voltage load shedding based on voltage stability index
Authors: Pérez Sandra , López Karol , Rodríguez Luis 
Published: September 2016

This paper presents a methodology for under voltage load shedding using a metaheuristic optimization technique and a stability criterion. Two strategies are proposed to find the minimal size and location of load to shed for the recovery of normal operation conditions. The first one is based on a classical criterion for the under voltage load shedding, identifying the load to disconnect by considering bus voltage level; the second includes a simplified voltage stability index SVSI, which identifies critical buses in the system. The proposed methodology is implemented in an IEEE 14 bus test system, considering a heavy loading condition with andwithout contingency to validate its efficiency.

Authors: Salazar Alzate Blanca Cecilia , Cortés Rodríguez Misael , Montoya Campuzano Olga 
Published: September 2016

Kefir grains are a consortium of bacteria and yeasts grouped in a polysaccharide called kefirano. They ferment sugar substrates to produce organic acids, CO2, vitamins and ethanol. They also have positive effects on health. This research project aimed to optimize the fermentation process of sugarcane concentrate using kefir grains. The microorganisms were first identified morphologically and biochemically, then isolated and purified in selective media. Optimization was conducted using the response surface methodology with a composite central design. The independent variables were: temperature, time and percentage of kefir grains added. As for dependent variables, we considered the following: increase in kefir grains (also measured as a percentage), acidity and microbial growth. Additionally, our study identified populations of Lactobacillus curvatus and the following yeasts: Candida famata, Can. magnoliae, Can. krusei/incospicua and Can. sphaerica in the kefir grains. The optimal conditions were 33.5 °C, 30 h and 6% w/w of added kefir grains. The increase in kefir grains reached was of 193 ± 12%. The lactobacilli, lactococci and yeast counts were 1.57x108, 8.63x107 and 2.05x107 CFU mL-1 respectively. Experimental optimization was an effective tool for the fermentation of kefir grains in sugarcane concentrate.

Published: September 2016

This investigation aimed to evaluate two varieties of Ocimum basilicum L., known as Basil, as potential raw material for the cosmetic industry, assessing their antioxidant properties, considering their industrial use in phytocosmetics. The antioxidant activity of essential oils (EOs) for the species Ocimum basilicum var. cinammom and var. album, were obtained by distillation steam using a Clevenger-type device. The antioxidant capacity was evaluated by the method of bleaching radical 1,1-diphenyl-2-picryl hydrazyl (DPPH) and the method of linoleic acid peroxidation (ferric thiocyanate). The EOs of the two species had significant antioxidant properties. The method of DPPH facilitated the evaluation of the antioxidant capacity versus the concentration of EOs, showing an efficient concentration at 10 ppm. On the other hand, the ferric thiocyanate method displayed an efficient inhibition up to 360 h (15 d). The obtained results demonstrated the antioxidant capacity of EOs in the investigation. The capacity was related to their chemical composition (phenylpropane and oxygenated monoterpenes). Therefore, EOs can be considered as a potential source in the field of phytocosmetics.
Effect of the acetylation process on native starches of yam (Dioscorea spp.)
Authors: Salcedo Mendoza Jairo , Hernández RuyDiaz Jorge , Fernández Quintero Alfredo 
Published: September 2016

In Colombia, it is necessary to produce native and modified starches for the use of amylaceous raw materials of major socioeconomic importance. In this study, the effects of the acetylation process on structural, morphological and functional properties of native starches yam, Dioscorea spp. (D. alata and D. rotundata) were evaluated. Chemical modification by esterification with acetic anhydride was performed at different reaction times, and morphological and structural changes were assessed using the following techniques: infrared spectroscopy (FTIR), X-ray diffraction and scanning electron microscopy (SEM). Acetylation produced slight changes in the granule morphology, and a decreased degree of crystallinity (DC) associated with a slight increase in the amylose content was observed. The introduction of acetyl groups into the starch structure caused a decrease in the gelatinization temperature and an increased retro gradation tendency. The acetylated starches had low degrees of substitution (DS<0.2), meaning they can be used in the food industry, considering that they showed greater stability, greater water absorption capacity and better solubility than native starches.

Absztrakt
A belgyógyászati módszerekkel panasz- és tünetmentessé nem tehető
gastrooesophagealis refluxbetegségben szenvedő betegek kezelésére bevált módszer
a laparoszkópos antireflux-sebészet. Gyakorlatot szerzett sebészek nagy
biztonsággal végzik a műtétet, mégis fellépnek intraoperativ, korai postoperativ
és késői szövődmények, amelyek reoperációt tehetnek szükségessé. A Pécsi
Tudományegyetem Sebészeti Klinikáján 1998 és 2015 között 407 laparoszkópos
antirefluxműtétet végeztünk. A periódust két szakaszra osztottuk. Az elsőben
1998 és 2006 között 241 beteget operáltunk és a vizsgálat prospektív volt;
minden diagnosztikus eljárást magunk végeztünk. A második periódusban 166
beteget kezeltünk minimálisan invazív módszerrel és az eredményeket
retrospektíve elemeztük. Az összbeteganyagban a férfi/nő arány 161/246 volt. A
betegek átlagéletkora 53,1 év volt. A 407 műtétet kiegészítettük 27 esetben
ligamentum teres plasztikával, 28 esetben hálóbeültetéssel és négy esetben
fascia lata plasztikával, mert a hiatus direkt zárását nem tartottuk
megbízhatónak. 16 esetben (4%) végeztünk konverziót, a halálozás 0,5% volt. 39
esetben végeztünk laparoszkópos reoperációt és hat esetben thoracolaparotomiás
reoperációt (12%). Ehhez még öt reoperáció járul, amelynél a primer műtét nem
klinikánkon történt. A 4%-os konverziós ráta, a 12%-os reoperációs arány,
valamint a 0,5%-os halálozás megfelel az irodalomban talált arányoknak.
Összességében megállapíthatjuk, hogy a laparoszkópos antirefluxműtét
biztonsággal és nagyon jó eredménnyel végezhető beavatkozás. A tartós
szövődmények (elsősorban reflux- és sérvkiújulás), illetve a reoperációk szinte
kizárólag csak a nagyméretű hiatusherniák sebészi kezelése kapcsán fordultak
elő.

<p>Henoch-Schönlein purpura (HSP) is an acute, systemic vasculitis which usually occurs in young adults and children. The skin involvement may lead to the manifestation of symptoms associated with vasculitis in intestines, kidneys, and the central nervous system. The incidence of bowel perforation in course of HSP is very seldom and it occurs about 10 days after the appearance of the first symptoms. We present a 23-year-old male patient with jejunal intussusception in the course of HSP. The patient was operated urgently with resection of part of the small intestine. Adults rarely suffer from the occurrence of abdominal pain and fever, but sometimes they require careful monitoring and surgical intervention because misdiagnosis can be life threatening.</p><p class="Standard"> </p>

Published: September 2016

<p>Esta investigación busco identificar los perfiles de cultura organizacional en cuatro sectores productivos de Bogotá, e investigar la asociación de estos perfiles con su desempeño innovador. Con el modelo y formulario de encuesta de Denison (1998, 2005), se tomo una muestra de 141 empresas pertenecientes cuatro subsectores para estimar los perfiles sectoriales de cultura organizacional. Contrariamente a lo esperado, en este estudio, no se encontraron diferencias significativas entre los perfiles generales de cultura corporativa de los sectores, aunque se encontraron diferencias en los grados de asociación entre innovación y las variables de cultura organizacional de cada sector. Sí se encontraron diferencias en los puntajes de las variables de cultura organizacional de las empresas innovadoras frente a las poco innovadoras que pertenecen a los mismos sectores. Finalmente se confirma asociación estadística entre las características de cultura organizacional e innovación, encontrando que la discriminación por sectores también explica la innovación.</p>
