Examining the Connections within the Startup Ecosystem: A Case Study of St. Louis
Authors: Motoyama Yasuyuki , Knowlton Karren
Published: January 2017

We critically examine how an entrepreneurial ecosystem is structured using an exploratory and bottom-up approach. Past studies in this area have discussed the presence of elements in the system or captured the ecosystem as holistically as possible by extending to social, cultural, and institutional dimension. However, we find that such aggregated conceptualizations gave limited understanding to how different elements are connected and constitute the system. Here, we apply a social network approach by analyzing the connections of the ecosystem at multiple layers: (1) among entrepreneurs, (2) among support organizations, and (3) between and among entrepreneurs and key support organizations. Through a series of interviews with entrepreneurs and support organizations in St. Louis, we find that the ways in which support organizations in this region interacted with each other and with entrepreneurs, including explicit cross-organizational collaboration and strategic structuring of resources, significantly impacted the way that entrepreneurs interacted with one another and with organizations, thus deepening our understanding of these connections and identifying intervening points within the ecosystem.
Towards the Interactive Effects of Demand Response Participation on Electricity Spot Market Price
Authors: Mohajeryami Saeed , Doostan Milad , Moghadasi Seyedmahdi , Schwarz Peter
Published: January 2017

The electricity market is threatened by supply scarcity, which may lead to very sharp price spikes in the spot market. On the other hand, demand-side’s activities could effectively mitigate the supply scarcity and absorb most of these shocks and therefore smooth out the price volatility. In this paper, the positive effects of employing demand response programs on the spot market price are investigated. A demand-price elasticity based model is used to simulate the customer reaction function in the presence of a real time pricing. The demand achieve by DR program is used to adjust the spot market price by using a price regression model. SAS software is used to run the multiple linear regression model and MATLAB is used to simulate the demand response model. The approach is applied on one week data in summer 2014 of Connecticut in New England ISO. It could be concluded from the results of this study that applying DR program smooths out most of the price spikes in the electricity spot market and considerably reduces the customers’ electricity cost.
FDI and Intra-industry Trade in the Automotive Industry in the New EU Member States
Authors: Ambroziak Łukasz
Published: January 2017

This paper investigates the extent to which foreign direct investment (FDI) influenced intra-industry trade (IIT) in automotive products in six New EU Member States (the Czech Republic, Hungary, Poland, Romania, Slovakia and Slovenia) in the 1995–2014 period. Changes in IIT intensity are analysed using the Grubel-Lloyd indices. To examine the IIT pattern, IIT indices are divided into two types of trade: IIT in vertically differentiated products (low and high quality VIIT) and IIT in horizontally differentiated products (HIIT). The research indicates that IIT in automotive products allowed manufacturers and consumers from the new EU Member States to benefit more from international trade. FDI inflow to the automotive sector of the NMS has been a key factor shaping IIT in automotive products.
Internationalization of the Entrepreneurial Activity of Social Purpose Organizations
Authors: Kusa Rafał
Published: January 2017

The objective of this paper is to analyse and identify patterns of international entrepreneurial activity of social purpose organizations. The article utilizes international social entrepreneurship literature to develop an understanding of the international activity of social entrepreneurs and to identify factors that differentiate their activity. A cluster analysis was conducted to identify patterns of international social entrepreneurial activity, which included: the subject of activity, the types of beneficiaries, the scope of activity, and the legal type of organization. As a result, a survey sample of 55 international social ventures was divided into 3 homogeneous groups. The groups were (1) solution providers, (2) entrepreneurial charities, and (3) intermediaries. The results of the analysis show the diversity of the international activities of social entrepreneurs, although only a portion of them operate internationally. These findings contribute to a greater understanding of social entrepreneurs’ motivation and the paths of their internationalization activity.
Perceived Service Quality and Customer Loyalty: The Mediating Effect of Passenger Satisfaction in the Nigerian Airline Industry
Authors: Rahim A. Ganiyu
Published: January 2017

The long-term survival and competiveness of the airline business is strongly connected to the quality of service offered by airline operators and their ability to satisfy and build long-term relationships with customers. This study investigates the relationship among service quality, customer satisfaction and loyalty in the Nigerian airline industry. The cross-sectional survey research design was chosen in order to collect the primary data, using a structured questionnaire. Convenience sampling was adopted to draw a sample of 800 respondents. The data collected were analysed using correlation and multiple regression analysis. The findings of this study largely support the hypothesized relationships proposed in the conceptual framework. The results specifically reveal that perceived service quality is positively related to both passengers’ satisfaction and loyalty. The relationship between passenger satisfaction and loyalty towards the airlines was also found to be positive. The mediating effect of customer satisfaction between perceived service quality and customer loyalty is also found to be positive and partially supported. On the basis of the findings of this study, we conclude that perceived service quality does influence passenger satisfaction, and by extension, loyalty to the airlines. Thus, improvement of service quality is an adjuvant factor to sustainable differentiation and competitiveness in the airline industry. We therefore, recommend that airline operators develop and implement market-oriented service strategies to identify customers’ needs and expectations in order to serve them better. Additionally, airline operators should measure service quality regularly to assure that they are keep meeting passengers’ expectations, and consider customizing their products and services (as needed) to enhance customer satisfaction and loyalty.
Temporal analysisof urban changes and development in Warsaw’s ventilation corridors
Authors: Wicht Marzena , Osińska-Skotak Katarzyna
Published: January 2017

This paper presents the results of the urban indicators analysis conducted within Warsaw’s ventilation corridors from 1992 to 2011. The literature review shows that the Floor Area Ratio (FAR) index is one of the best indicators to detect urban development; therefore, this was the core of the analysis. Three periods were analysed (1992 – 2002 – 2011), as such a long time-span allows the assumption that change will be visible. The ventilation corridors were divided into 500 m and 100 m grids and the FAR index was calculated for each cell. The results highlight alarming changes within some of the corridors, indicating areas that are crucial to sufficient air flow in Warsaw.

Digesting the League of Nations: Planning the International Secretariat of the Future, 1941–1944
Authors: Auberer Benjamin
Published: January 2017

This article examines the administrative debates on the structure of the post-war international order that took place during the Second World War. By focusing on a multinational study group composed of former high ranking League of Nations civil servants affiliated with the Royal Institute of International Affairs at Chatham House, it elucidates the activities of international civil servants after they left the League. It is shown how the group claimed to represent the experiences of the international secretariat of the League of Nations on a comprehensive scale by publishing a report on the evaluation of the League’s secretariat. An examination of the report investigates how the group defended the League of Nations and their own participation in the League.
The Politics of Music in International Organizations in the First Half of the Twentieth Century
Authors: Sibille Christiane
Published: January 2017

This article examines the activities of international organizations in the field of music in the first half of the twentieth century. Despite the common association with music as a universal language and international art, it has not often been systematically investigated in the context of institutionalized international co-operation. By focusing on the International Musical Society, the International Society for Musicology, the International Society for Contemporary Music, the Permanent Council for the International Co-operation between Composers, and the activities of the League of Nations in the field of music, it analyzes common topics and different strategies to establish stable networks and co-ordinate the flow of information. By locating the activities of the experts involved along the two analytical axes of nationalization/internationalization and politization/standardization, it becomes not only possible to integrate the activities in the field of music into the history of international organizations, but also to gain important insights into the international and political origin of musicology as an academic discipline.
Evaluation of NT-proBNP in children with heart failure younger than 3 years old
Authors: Iacob Daniela , Butnariu Angela , Leucuţa Daniel-Corneliu , Samaşca Gabriel , Deleanu Diana , Lupan Iulia
Published: January 2017

Introduction. Heart failure (HF) is characterized by neuroendocrine activation. The cardiac natriuretic hormones, including atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), together with their related pro-peptides (proANP and proBNP) represent a group of peptide hormones produced by the heart. A normal NT-proBNP level has a high negative predictive value for heart failure. The use of NT-proBNP testing is helpful in diagnosing acute HF in the emergency care setting, allowing an early and optimal treatment. The purpose of this study is to assess the prognostic value of NT-proBNP in heart failure in children younger than 3 years old and to establish whether it correlates with the NYHA/Ross functional class and left ventricle systolic function.

Methods. We enrolled 24 consecutive children with HF due to congenital heart diseases and dilated cardiomyopathy. The serum levels of NT-proBNP were measured, all patients underwent echocardiography and left ventricle ejection fraction was calculated.

Results. The highest median value of NT-proBNP was recorded in patients with cyanotic heart diseases (248.0 fmol/mL), p = 0.610. NT-proBNP had a negative correlation with the ejection fraction of the left ventricle: Spearman's rank correlation coefficient was −0.165.

Conclusions. NT-proBNP levels correlate with the severity of HF in infants and small children younger than 3 years old with heart failure due to congenital heart diseases and dilated cardiomyopathy.
Determinants of Research and Development Intensity from a Network Perspective
Authors: Teng Joe K.L. , Hu Jiayu , Wu Dazhong , Mixon Phillip A. , Duan Chaojie (CJ)
Published: January 2017

We model and examine the research and development (R&D) intensity of a focal industry from an inter-industry network perspective. More specifically, we estimate how a focal industry’s R&D investment is affected by partner (suppliers and customers) industries’ R&D expenditure. We also investigate the impact of the overall economy on the focal industry’s R&D expenditure and finally how a focal industry’s position in the supply chain network moderates the overall economy’s impact on the focal industry’s R&D expenditure. We found that, in general, a focal industry’s R&D intensity is positively associated with its partner industries’ R&D intensity. In addition, an industry’s R&D intensity is positively associated with the growth rate of the overall economy. Finally, we found that a more central industry is subjected to a stronger impact of macroeconomic shocks on its R&D intensity though there is no significant association between an industry’s centrality and its R&D intensity.
The Socioeconomic Impacts of Casino Tourism in Slovenia’s Obalno-Kraška Region
Authors: Balažič Gregor
Published: January 2017

Casino gambling in the Obalno-kraška region has had a long tradition, its origins dating back to the beginning of the 20th century. Ever since its rebirth during Yugoslav times in the 1960s, casino tourism has contributed significantly to the development of the area. Until recently, casino tourism has been one of the most important forms of tourism in addition to 3S and congress tourism. The purpose of this paper is to determine the contribution of casino tourism to the regional development of the Slovene Istria. To this end, selected socioeconomic indicators were examined and compared with the average indicator rates of regional development at the national level. The results show that casino tourism is an important factor of regional development. However, casino tourism’s future role in regional development remains an open question due to the impacts of the financial crisis and the consequent decline in the number of guests, as well as reduced levels of investment in the region.

Published: January 2017

Infertility is currently a common problem with causes that are often unexplained, which complicates treatment. In many cases, the use of ART methods provides the only possibility of getting pregnant. Analysis of this type of data is very complex. More and more often, data mining methods or artificial intelligence techniques are appropriate for solving such problems. In this study, classification trees were used for analysis. This resulted in obtaining a group of patients characterized most likely to get pregnant while using in vitro fertilization.
Persistence of Strength/Toughness in Modified-Olefin-Fiber- and Hybrid-Fiber-Reinforced Concrete
Authors: Zhu H. , Li C. , Wu M. , Yan M. , Jiang Z.
Published: January 2017

This paper investigates the flexural performance of modified-olefin-fiber- (MOF) and hybrid-fiber-reinforced concrete. The standards and methodologies that are commonly used to evaluate the flexural performance of fiber-reinforced concrete are also discussed. Persistence of strength/toughness (PST) was introduced to evaluate the safety and economics of fiber-reinforced concrete. By comparing the modulus of rupture and the limit of proportionality, the PST can be easily and qualitatively obtained. This method agrees with the toughness index. PST can serve as an excellent supplement to the traditional standards and methods that evaluate the strength and toughness of fiber-reinforced concrete. The test results demonstrate that using hooked steel fibers increased the flexural strength and toughness most. The hybridization of the MOFs and the hooked steel fibers, and the addition of MOFs improved the PST.
Simple Method of Using Strain Gages to Estimate Stress Fields Near a Notch in Structures Subject to Large Deflections
Authors: Morita N. , Harada T. , Noguchi H.
Published: January 2017

This study set out to estimate the stress fields in notched plates subject to large deflections. Because there are no general solutions to the von Karman equations defining this problem, the goal of the authors was to estimate the stress field for a large-deflection problem by superposing the stress fields of two solvable linear problems, that is, a bending problem and a plane problem. This paper described the procedure for estimating the stress fields in a plate with a circular hole, subject to a large deflection. By using strain gages and the equations describing the stress fields near the root of a notch in a plate subject to out-of-plane bending and in-plane deformation, the unknown coefficients of the equations were determined by the stress values obtained from rosette-type strain gages and the method of least squares. The rosette-type strain gages are located on a circular arc with a radius that is 1.5 times greater than the notch root radius. The estimated maximum stress values at the notch root were compared with those obtained by finite element analyses. The estimated values were found to be nearly equal to those obtained by finite element analysis, provided the ratio of the maximum deflection to the plate thickness is less than 0.8.
Effect of Moisture Hysteresis on the Resilient Modulus of Lime-Treated Expansive Clay
Authors: Elkady Tamer Y. , Al-Mahbashi Ahmed M. , Al-Shamrani Mosleh A.
Published: January 2017

Several studies have asserted that seasonal moisture variation of unsaturated subgrade has a significant impact on its resilient modulus and, consequently, on the pavement performance and longevity. In regard to unsaturated lime-treated expansive subgrade, little research has addressed the influence of moisture variation on resilient modulus (MR). In this context, this study aims at evaluating the effect of the drying and wetting cycle on the resilient behavior of lime-treated expansive clay at optimum lime conditions. Initially, the effects of lime content and curing period on the MR of lime-treated expansive clay were investigated to evaluate the optimum lime content. This involved conducting a series of repeated load tests under different lime contents and curing periods. In addition, a complementary series of tests were conducted to evaluate the unconfined compression strength along the same drying and wetting paths. Test data indicated that lime treatment resulted in a 370 % increase in the MR after 28 days curing. On the other hand, the effect of the wetting and drying cycle, depicted as the relationship between MR and suction (or water content), showed a hysteresis phenomenon. Further examination of the MR along the drying path indicated a positive contribution of suction to the resilient behavior of lime-treated samples up to a specific suction value (>20 MPa), after which this contribution is considered negligible. Hysteresis phenomenon was also observed for unconfined compression strength because of wetting and drying; however, with a different trend. The discrepancy between hysteresis trends were attributed to differences in loading characteristics.
Ick Ciliary Kinase Is Essential for Planar Cell Polarity Formation in Inner Ear Hair Cells and Hearing Function
Authors: Okamoto Shio , Chaya Taro , Omori Yoshihiro , Kuwahara Ryusuke , Kubo Shun , Sakaguchi Hirofumi , Furukawa Takahisa
Published: January 2017

Cellular asymmetries play crucial roles in development and organ function. The planar cell polarity (PCP) signaling pathway is involved in the establishment of cellular asymmetry within the plane of a cell sheet. Inner ear sensory hair cells (HCs), which have several rows of staircase-like stereocilia and one kinocilium located at the vertex of the stereocilia protruding from the apical surface of each HC, exhibit a typical form of PCP. Although connections between cilia and PCP signaling in vertebrate development have been reported, their precise nature is not well understood. During inner ear development, several ciliary proteins are known to play a role in PCP formation. In the current study, we investigated a functional role for intestinal cell kinase (Ick), which regulates intraflagellar transport (IFT) at the tip of cilia, in the mouse inner ear. A lack ofIckin the developing inner ear resulted in PCP defects in the cochlea, including misorientation or misshaping of stereocilia and aberrant localization of the kinocilium and basal body in the apical and middle turns, leading to auditory dysfunction. We also observed abnormal ciliary localization of Ift88 in both HCs and supporting cells. Together, our results show that Ick ciliary kinase is essential for PCP formation in inner ear HCs, suggesting that ciliary transport regulation is important for PCP signaling.

SIGNIFICANCE STATEMENTThe cochlea in the inner ear is the hearing organ. Planar cell polarity (PCP) in hair cells (HCs) in the cochlea is essential for mechanotransduction and refers to the asymmetric structure consisting of stereociliary bundles and the kinocilium on the apical surface of the cell body. We reported previously that a ciliary kinase, Ick, regulates intraflagellar transport (IFT). Here, we found that loss of Ick leads to abnormal localization of the IFT component in kinocilia, PCP defects in HCs, and hearing dysfunction. Our study defines the association of ciliary transport regulation with PCP formation in HCs and hearing function.

Published: January 2017

Picea abies and Larix decidua were subjected to GC/MS analyses, and antimicrobial (fungi and bacteria) assays of their stem wood and bark extracts were investigated. L. decidua bark extract exhibited the highest antifungal and antibacterial activities against the microorganisms that were screened. The microbes Penecillium ochrochloron and Aspergillus ochraceus were the most sensitive to the extracts, whereas Candida albicans was the most resistant fungus. L. decidua wood and bark did not exhibit much variation in their antibacterial activities, except against Micrococcus flavus and Pseudomonas aeruginosa. The bacterium most sensitive to the extracts was Escherichia coli, whereas the most resistant was M. flavus. 13-epimanool and α-cedrol were the main components of P. abies wood extract. The main components in its bark were abietic acid, astringin, dehydroabietic acid, and α-terpineol. The main chemical compounds in L. decidua wood extract were abietic acid, oleanolic acid, duvatrienediol, and larixol. The main chemical compounds in its bark were (-)-2,9-dihydroxyverrucosane and larixol. The study revealed that P. abies and L. decidua stem wood and bark extracts contain several compounds that have antimicrobial activities towards diverse human pathogenic, food, and agricultural microbes. These results might guide in future searches for novel natural products with chemotherapeutic uses.
A Review on the Tensile Properties of Bamboo Fiber Reinforced Polymer Composites
Authors: Md Shah Ain Umaira , Sultan Mohamed Thariq Hameed , Jawaid Mohamad , Cardona Francisco , Abu Talib Abd. Rahim
Published: January 2017

This paper reviews the tensile properties of bamboo fiber reinforced polymer composites (BFRP). Environmentally friendly bamboo fibers have good mechanical properties, which make them suitable replacements for conventional fibers, such as glass and carbon, in composite materials. Better fiber and matrix interaction results in good interfacial adhesion between fiber/matrix and fewer voids in the composite. Several important factors improve matrix-fiber bonding and enhance the tensile properties of BFRP. Coupling agents, such as maleic anhydride polypropylene (MAPP), improve the adhesion of bamboo fibers in the polypropylene (PP) matrix. A high percentage of lignin content in bamboo fibers limits fiber separation, which leads to less matrix absorption between fibers. Steam explosion is the best extraction method for bamboo fibers, although an additional mechanically rubbing process is required for fiber separation. Generally, high fiber content results in good composite performance, but at a certain limit, the matrix does not adhere well with a saturated amount of fibers, and the composite tensile strength decreases. However, the tensile modulus of BFRP is not affected by excess fiber content. Hybridization of bamboo with conventional fibers increases the tensile strength of BFRP. The addition of micro/nano-sized bamboo fibrils into the carbon fabric composites slightly enhances composite strength.
Outcomes From a Hearing-Targeted Cytomegalovirus Screening Program
Authors: Diener Marissa L. , Zick Cathleen D. , McVicar Stephanie Browning , Boettger Jill , Park Albert H.
Published: January 2017

BACKGROUND AND OBJECTIVES:

Cytomegalovirus (CMV) is the most common congenital infection and nongenetic cause of congenital sensorineural hearing loss in the United States. Utah was the first state to pass legislation mandating CMV screening for newborns who fail newborn hearing screening (NBHS). The study objective was to present outcomes of hearing-targeted CMV screening and determine factors predicting CMV screening.

METHODS:

We used Utah Department of Health HiTrack and Vital Records databases to examine CMV screening from 509 infants who failed NBHS in the 24 months after implementation of the Utah legislation. Multivariate logistic regression analyses were conducted to identify predictors of compliance with CMV screening and diagnostic hearing evaluation.

RESULTS:

Sixty-two percent of infants who never passed hearing screening underwent CMV screening. Fourteen of 234 infants tested within 21 days were CMV positive; 6 (42.9%) had hearing loss. Seventy-seven percent of eligible infants completed a diagnostic hearing evaluation within 90 days of birth. Compliance with CMV screening was associated with sociodemographic factors, time since the law was enacted, and NBHS protocol. Infants born after the legislation showed greater odds of achieving timely diagnostic hearing evaluation than infants born before the law.

CONCLUSIONS:

Incorporating CMV screening into an established NBHS program is a viable option for the identification of CMV in infants failing NBHS. The addition of CMV testing can help a NBHS program attain timely audiological diagnostics within 90 days, an important early hearing detection and intervention milestone.

Lo monstruoso femenino y la violencia simbólica en la Hécabe de Eurípides
Authors: Álvarez-Espinoza Nazira
Published: January 2017

En el discurso literario antiguo el monstruo y monstruosidad en la mitología, el arte, la religión, la ciencia y los textos literarios se asocia con lo extraño, lo maravillosos o lo fantástico determinado por el contexto geográfico, cultural y temporal. En la Grecia antigua el análisis de personajes literarios monstruosos en la tragedia Hécabe de Eurípides, involucra las representaciones textuales imaginarias sobre acciones monstruosas femeninas. La aproximación al texto del trágico ateniense desde los ejes de género, violencia contra las mujeres en el discurso literario antiguo permite mostrar los aspectos de lo monstruoso asociado a los personajes femeninos de la tragedia griega.
La representación del espacio familiar como ominoso en la literatura costarricense: de La ruta de su evasión a Larga noche hacia mi madre
Authors: Sanabria Carolina
Published: January 2017

En la literatura costarricense, el tema de lo familiar ha sido tratado con cierta irregularidad desde sus inicios. Pero con la publicación de La ruta de su evasión (1949) de Yolanda Oreamuno, se produce un quiebre no solo a nivel temático, sino formal, en cuanto a la construcción de un universo íntimo desde un discurso de lo femenino a partir de técnicas dentro de las que sobresale el monólogo interior. La casa aparece como un espacio asfixiante que hace de los miembros de la familia seres extraños, que provoca sus respectivas evasiones, con lo que termina constituyéndose como un armazón hueco, unheimlich por cuanto funciona como instancia de represión. Esta atmósfera fantasmal en el mismo plano familiar es reelaborada, más de sesenta años después de su publicación, por otra novela, Larga noche hacia mi madre (1913) de Carlos Cortés, donde la casa adquiere matices más fantasmales que en la obra de Oreamuno. Sin embargo, en ambas lo siniestro emana desde la figura típicamente cohesionadora: la madre, y termina siendo una figura que está ligada a una función que niega la protección, de modo tal que solo su muerte puede permitir la liberación de sus miembros. Lo que se pretende, por tanto, es abordar la representación de lo familiar como ominoso en dos novelas que responden a momentos distintos de la literatura costarricense.
Coatlicue, la piedra, la palabra: somos indias. En Los recuerdos del porvenir y borderlands: la frontera. The new mestiza
Authors: Anzaldo-González Demetrio
Published: January 2017

Esta revalorización del arte de la Coatlicue reelabora mitos y desmitificaciones mantenidos al interior de una cultura mexicana colonizada que no ha sabido aprender del pasado ni ha podido apreciar lo que la gran piedra muestra desde sus orígenes. El México oficial sigue cavando su propia tumba, re-negando y eliminando a los millones de pobladores autóctonos que las constantes migraciones han llevado al ahora monstruoso territorio mexicano que comercializa y vende todo incluido el arte del pasado. Pero, los tiempos y miradas siguen cambiando; ahora existen pensadoras y escritoras que llegan al centro de las discusiones y acciones en el mundo de las artes y ciencias que comparten otras visiones. Estas palabras y piedra siguen tiñendo de rojo (sabiduría) y negro (escritura), los silencios sonoros en la historia; porque el mundo también es de las mujeres y no sólo de los monstruos misóginos. La fuerza escultural de Coatlicue y la literatura de Elena Garro junto a los planteamientos epistemológicos de Gloria Anzaldúa muestran que si algo tienen de monstruosas sus obras/personas es que se han alimentado de los monstruos que andan desatados. Las solidarias y diferentes sociedades que potencializan con sus textos siguen siendo desafíos que esperan mejores respuestas.
De lo mítico a lo profano: Chac Mool como monstruo
Authors: Herrera-Ávila Tatiana
Published: January 2017

Este artículo analiza el cuento “Chac Mool” (Los días enmascarados, 1954) de Carlos Fuentes y la construcción del carácter monstruoso del personaje homónimo, desde la categoría freudiana de lo Unheimlich, esto es lo familiar que ha dejado de serlo. Se abordan específicamente las nociones del doble y la totalidad, de manera que se explica cómo la naturaleza divina y la naturaleza monstruosa, en realidad, se constituyen en caras de la misma moneda. El Chac Mool aparecerá como monstruoso, no solo por su carácter de dios, sino y sobre todo porque para seguir viviendo requiere de la inmolación o el sacrifico del humano, Filiberto, a quien el Chac Mool sustituye, en algún sentido, al final del texto. Se produce así una irrupción de lo mítico en lo profano, y dicha irrupción es, como se verá, monstruosa.

El general en su laberinto: Voz narrativa y verosimilitud
Authors: Vargas-Vargas José Angel
Published: January 2017

En este artículo se analiza la voz narrativa en la novela El general en su laberinto (1989) de Gabriel García Márquez, con el objetivo de determinar aquellas formas o mecanismos que contribuyen a la verosimilitud textual, a mostrar como creíbles los acontecimientos representados, así como la historia personal y colectiva del prócer Simón Bolívar. Concretamente, se estudia la función que cumple el narrador omnisciente, la introducción del estilo directo y el empleo de primera persona singular y plural. Con base en lo anterior, se concluye que estas formas permiten articular el discurso histórico y el discurso literario y con ello construir una historia verosímil en la que se develan los aciertos y contradicciones del proyecto bolivariano de la unión latinoamericana.

Authors: Vásquez Luz Marina
Published: January 2017

Spanish has a rich verb inflectional system with up to 53 inflectional verb forms distributed between regular and irregular verbs and in which roots are always bound, as verbs must contain markings for person, tense/aspect, and number. The acquisition of verb morphology by native speakers reportedly reflects this complexity in that children produce multiple non-target-like forms wherein tense, person, and number errors are found. This study reports all verb forms identified in the spontaneous speech by a group of 15 native Spanish-speaking children ages 3;6 to 5;6. The analysis of all 233 verb forms analyzed revealed some pronunciation errors, number agreement errors, errors in the use of clitic pronouns, and incorrect use of person and tense agreement.  The majority of non-target-like forms identified consisted of regularization of verb forms wherein regular conjugation morphemes were attached to irregular verbs. A few –ar type verbs additionally showed ir-regularization of regular verbs, as children used conjugations which apply to irregular verbs with regular verbs.

Historias de tránsitos y transgresiones del género en el armario de Orlando de Virginia Woolf
Authors: Frye Córdoba Mélida Paola , Gutiérrez José Ismael
Published: January 2017

El presente artículo de reflexión analiza la novela Orlando, publicada por Virginia Woolf en 1928. Esta obra se estudia como un texto crítico-reflexivo frente a temas como el género, los trajes, la moda y los estereotipos de género. Es por ello que se analizan los episodios clave de la obra en los cuales su protagonista transgrede convenciones sociales a través de los trajes hasta los momentos del travestismo. De igual forma se estudia la incidencia de estos cambios de trajes, de rol social y de género como transgresiones a la normatividad.
Felületes vénás thrombosis – ahogy ma látjuk
Authors: Sándor Tamás
Published: January 2017

Abstract:

For a long time superficial thrombophlebitis has been thought to be a rather benign condition. Recently, when duplex ultrasound technique is used for the diagnosis more and more often, the disease is proved to be more dangerous than anticipated. Thrombosis propagates to the deep veins in 6–44% and pulmonary embolism was observed on the patients in 1,5–33%. We can calculate venous thromboembolic complications on every fourth patient. Diagnosis is clinical, but duplex ultrasound examination is mandatory, for estimation of the thrombus extent, for exclusion of the deep venous thrombosis and for follow up. Both legs should be checked with ultrasound, because simultaneous deep venous thrombosis can develop on the contralateral limb. Two different forms can be distinguished: superficial venous thrombosis with, or without varicose veins. In cases of spontaneous, non varicous form, especially when the process is migrating or recurrent, a careful clinical examination is necessery for exclusion of malignant diseases and thrombophilia. The treatment options are summarised on the basis of recent international consensus statements. The American and German guidelines are similar. Compression and mobilisation are cornerstones of the therapy. For a short segment thrombosis non steroidal antiinflammatory drugs are effective. For longer segments low molecular-weight heparins are preferred. Information on the effect of the novel oral anticoagulants for the therapy is lacking but they may appear to be effective in the future for this indication. When thrombus is close to the sapheno-femoral or sapheno-popliteal junction crossectomy (high ligation), or low molecular-weight heparin in therapeutic doses are indicated. The term superficial thrombophlebitis should be discouraged, because inflammation and infection is not the primary pathology. It should be called correctly superficial venous thrombosis in order to avoid the unnecessary administration of antibiotics and the misconception, that superficial venous thrombosis is benign disease.

TEKNIK PENGAPURAN PADA PEMATANG TAMBAK TANAH SULFAT MASAM
Authors: Arnol Muhammad
Published: January 2017

Salah satu jenis tanah pantai bermasalah untuk pengembangan budidaya tambak adalah tanah sulfat masam (TSM) karena sifatnya yang masam serta mempengaruhi tingkat kelarutan bahan-bahan toksik seperti Al atau Fe yang tinggi. Pengapuran merupakan metode remediasi yang paling umum dikembangkan oleh petani untuk mengantisipasi permasalahan TSM tersebut. Tulisan ini bertujuan untuk menguraikan jenis, dosis, dan teknik pengapuran yang diaplikasikan sehubungan dengan karakteristik umum tanah pematang tambak TSM. Dari berbagai variabel kimia TSM yang diukur di laboratorium, secara umum nilai sulfur yang dapat teroksidasi (SPOS) dari contoh tanah dapat digunakan sebagai dasar untuk menentukan tingkat aplikasi kapur. Teknik pengapuran dapat dilakukan dengan metode berlapis untuk pematang yang baru dibangun atau dengan penetralan tanah yang baru terangkat untuk pematang lama saat proses keduk teplok.
INTER-SPECIFIC COMPETITION AND FISHING EFFECT TO POPULATION DYNAMIC OF BALI SARDINE (SARDINELLA LEMURU)
Authors: Prasetyo Andhika Prima , Purwoko Rudy Masuswo
Published: January 2017

Stock-recruitment relationship of Bali sardine was investigated based on Beverton-Holt model by assuming inter-specific competition. Model is modified to incorporate the effect of fishing pressure that is density-independent to population dynamic by developing scenario fishing on adult and/or juvenile population. The results show that harvested adult the dramatic decline of recruitment supply. However, harvested juvenile is led to the positive response to population size, as an increase in fishing mortality rate will reduce competition mortality rate. Precautionary approach required by considering bipartite life cycle.

A 3-year-old sheep was examined after an acute onset of hind limb paralysis and ataxia. At necropsy, central nervous system, pulmonary and intestinal hyperaemia and ecchymoses in the aortic arch were observed. Main microscopic lesions were confined to the heart, cerebrum and cerebellum. There were a multifocal mild myocarditis and nonsuppurative meningoencephalitis together with protozoal cysts in the heart and the brain. Protozoal cystic structures were observed within many of the myocardial fibers as well as in the cerebrum and cerebellum. Using light microscopy it could not be morphologically determined whether these organisms were Toxoplasma (T.) gondii or Neospora (N.) caninum. Additional diagnostic methods like immunohistochemistry and polymerase chain reaction provided differentiation of Sarcocystis from T. gondii and N. caninum. Transmission electron microscopy demonstrated characteristic features of Sarcocystis sp. as previously described. This is the first confirmed diagnosis of Sarcocystis sp. in the central nervous system of a sheep from Turkey.
Metodyczne aspekty badania zaufania w naukach o zarządzaniu

Published: January 2017

This article presents an overview of the problems associated with the study of trust in management science. Trust can be considered in various contexts and ranges. Its varied sources and dimensions, cultural roots and numerous other features have made it difficult to analyse and reconcile in the research done by various authors. Another reason studying trust is difficult is that it is a cognitive construct, and it is often researched based on the subjective perception of respondents. The article attempts the most comprehensive approach to issues of trust with regard to the problems associated with measuring it.

The basis for using psychological testing in management is the assumption that the individual’s psychological predisposition is an essential element used to match individuals to professional tasks. The test procedures are therefore used most commonly in organisations in three situations: selecting employees to hire, assigning them to an appropriate job, and development and career planning.The article presents psychological tests as a tool for use in business practice. It describes the history of psychological measurement and presents the results of research on the use of testing in organisations in the twenty-first century. The final part of the article presents the main directions of change in the rules governing the use of testing in business and identifies areas that require special sensitivity.
A Late Night at the University Library: Supporting Students in the Final Phases of Essay and Thesis Writing
Authors: Moberg Bodil , Borgström Anna M.
Published: January 2017

This poster outlines a strategy for both efficient use of library resources towards the end of semesters – when the library is filled with students stressed about essays and theses – and at the same time for caterings to students’ needs. For the past four semesters, the Karolinska Institutet University Library has arranged “a late evening at the library”, with a special program designed to help students. Our goal is that the students should be able to finish their work during the evening.  We seek to provide an opportunity for focused work with access to the resources that the students are asking for: drop-in consultations and mini lectures with writing tutors and librarians. To help the students stay focused and energized, the student health center offers advice on how to end procrastination, an instructor from the campus gym leads mini-exercise and yoga breaks, and complimentary snacks are offered. The event was inspired by the international “long night against procrastination”, which started in Germany 2010.The late night at the library makes for a new way of reaching students and catering to their needs in a time-efficient manner. Although these evenings require some preparation, we are able to reach many students. In addition, students have the opportunity to get iterative support during their working process, allowing for highly efficient and stimulating work. Student response has been positive, and many students have used the opportunity to work intensely and make use of the support offered – some of them have also managed to finish their work during the evening!
