Battir: Creative Resistance in a Front Line—Opportunities and Dilemmas of Tourism Development in a Conflict Zone
Authors: Kuntz Andreas F.
Published: May 2019

Tourism development in a conflict zone poses challenges. The structural violence of occupation poses real threats to the existence of the village. Battir's inhabitants can build on a tradition of non-violent, creative resistance. Hasan Mustafa initiated creative resistance in 1948 and
saved the village from destruction. In retelling the motivations, facts, and events in Battir 1948 a tour guide speaks also about creativity, community, and opportunities for change. In terms of economic dynamics of Holy Land tourism Battir's inhabitants are excluded by Israeli marketing,
while Palestinian marketing still needs profiling and fresh ideas. But meanwhile other dynamics appear in Battir: Inhabitants have started to react to the UNESCO World Heritage status of village lands and traditional agriculture, and offer services to visitors. Local products are sold and
the beauty of the village can be enjoyed by sitting down with a cup of coffee. Because tourism is new to the village, the cultural dynamics unfolding could be influenced by the inhabitants if tourism would be formed consciously beyond the marketing for more visitors. The amazing story of Hasan
Mustafa is an asset for a touristic Battir experience in the framework of a conflict-sensitive tourism. Is the immaterial inheritance, especially the stories about creative resistance, part of the future tourism product, an add-on to UNESCO World Heritage status? The stories still have to
be put together to form a reflected narrative that motivates to recognize one's own role in the conflict and the perspective towards change. Therefore, Palestinian tour guides can play a decisive role. This role and the impact of a reflected narrative cannot be underestimated. It is possible
to contribute to an awareness of visitors beyond mere contact at a touristic site. Battir can be a sample for a tourism development that serves the village as a whole, if methods and ideas of conflict-sensitive tourism are applied. Inclusion of all stakeholders, a carefully developed strategy,
and income for the community and the local government are important to maintain the UNESCO World Heritage landscape. Information about threats and the structure of violence need to be part of the touristic products. With a guided learning experience Battir can continue the inheritance of creative
resistance.

A comment on “Variability in plant nutrients reduces insect herbivore performance”
Authors: Koussoroplis Apostolos-Manuel , Klauschies Toni , Pincebourde Sylvain , Giron David , Wacker Alexander
Published: May 2019

In their recent contribution, Wetzel et al. [Wetzel et al. (2016) Variability in plant nutrients reduces insect herbivore performance. Nature 539: 425-427] predict that variance in the plant nutrient level reduces herbivore performance via the nonlinear averaging effect (named Jensen’s effect by the authors) while variance in the defense level does not. We argue that the study likely underestimates the potential of plant defenses’ variance to cause Jensen’s effects for two reasons. First, this conclusion is based on the finding that the average Jensen’s effect of various defense traits on various herbivores is zero which does not imply that the Jensen’s effect of specific defense traits on specific herbivores is null, just that the effects balance each other globally. Second, the study neglects the nonlinearity effects that may arise from the synergy between nutritive and defense traits or between co-occurring defenses on herbivore performance. Covariance between interacting plant defense traits, or between plant nutritive and defense traits, can affect performance differently than would nutritive or single plant defense variance alone. Overlooking the interactive effects of plant traits and the traits’ covariance could impair the assessment of the true role of plant trait variability on herbivore populations in natural settings.
Column chromatography as a method for minor components removal from rapeseed oil
Authors: Rokosik E. , Dwiecki K. , Rudzińska M. , Siger A. , Polewski K.
Published: May 2019

The purpose of this study was to verify the influence of different chromatographic column beds (silicic acid, activated charcoal, aluminum oxide, silica gel) on the concentration of individual minor components (sterols, tocopherols, carotenoids and chlorophyll) in rapeseed oil. With the use of a combination of these beds, a three-stage optimized method for removing minor components from rapeseed oil was developed. It was demonstrated that the combination of silicic acid and activated charcoal removed about half of the sterols present from the oil. Aluminum oxide turned out to be the most effective bed in removing tocopherols, purifying the oil to their minimum level (2.6 mg/kg). All adsorbents used had similar capacity to purify oil from pigments (carotenoids and chlorophyll). In the three-stage purification process free sterols were almost completely removed (to the level 90.0 mg/kg). Purification of β-carotene and chlorophyll from the oil was also very effective. Tocopherols were completely removed with this method, except for a small amount of α-tocopherol (0.4 mg/kg), which results from its relatively weak interaction with a hydrophilic bed. The developed method may be used in studies on the effect of association colloids on bulk oil autoxidation processes.
CONCEPTUAL DEVELOPMENT OF THE EARTH TUBE COOLING SYSTEM FOR A TALL BUILDING
Authors: Liu Xiangfeng , Xu Miao , Guo Juanli , Zhu Renjie
Published: May 2019

Earth tubes are earth-to-air heat exchangers that are frequently utilized in energy conscious low-rise buildings, but are scarcely reported for tall buildings. The feasibility of applying earth tube cooling to tall buildings in a hot summer and cold winter climate zone was studied in this paper. Firstly, the designed cooling load of a tall building was obtained from the energy simulation using the baseline and the modified models with applicable energy efficiency measures. Based on the load, the required cooling capacity, the overall section area and the effective length of the earth tube system was deduced from the heat transfer and fluid flow calculation analytically. Then the performance of the earth tube system was crosschecked and verified via the Computational Fluid Dynamics (CFD) simulation. In the CFD simulation, earth tubes with different diameters and lengths, as well as a full-scale earth tube model with surrounding soil above the depth of constant temperature, were investigated. The outlet air temperatures of the full-scale models were computed with the consideration of different axial distances between adjacent tubes. Meanwhile, multiple conceptual design schemes and the tunnel construction method for the earth tube system were proposed from the perspective of performance enhancement, constructability, efficiency and economy. It revealed that earth tube systems are conditionally feasible for some tall buildings if their design guidelines for climate, underground spaces, construction method, friction of tube interior surface, optimization of effective length and axial distance, as well as synergy with other energy efficiency measures are followed. Even the cooling capacity of earth tubes degrade with time due to the accumulated heat underground, but in a hot summer and cold winter climate zone it can still possibly produce cooled air for a tall building with a Floor Area Ratio of less than 7 effectively in summer.
PERFORMANCE INDICATORS FOR ENERGY EFFICIENCY RETROFITTING IN MULTIFAMILY RESIDENTIAL BUILDINGS
Authors: Basu Chaitali , Paul Virendra Kumar , Syal M.G. Matt
Published: May 2019

The energy performance of an existing building is the amount of energy consumed to meet various needs associated with the standardized use of a building and is reflected in one or more indicators known as Building Energy Performance Indicators (EnPIs). These indicators are distributed amongst six main factors influencing energy consumption: climate, building envelope, building services and energy systems, building operation and maintenance, occupants' activities and behaviour, and indoor environmental quality. Any improvement made to either the existing structure or the physical and operational upgrade of a building system that enhances energy performance is considered an energy efficiency retrofit. The main goal of this research is to support the implementation of multifamily residential building energy retrofits through expert knowledge consensus on EnPIs for energy efficiency retrofit planning. The research methodology consists of a comprehensive literature review which has identified 35 EnPIs for assessing performance of existing residential buildings, followed by a ranking questionnaire survey of experts in the built-environment to arrive at a priority listing of indicators based on mean rank. This was followed by concordance analysis and measure of standard deviation. A total of 280 experts were contacted globally for the survey, and 106 completed responses were received resulting in a 37.85% response rate. The respondents were divided into two groups for analysis: academician/researchers and industry practitioners. The primary outcome of the research is a priority listing of EnPIs based on the quantitative data from the knowledge-base of experts from these two groups. It is the outcome of their perceptions of retrofitting factors and corresponding indicators. A retrofit strategy consists of five phases for retrofitting planning in which the second phase comprises an energy audit and performance assessment and diagnostics. This research substantiates the performance assessment process through the identification of EnPIs.

Published: May 2019

Çalışanların örgütsel değişime yönelik tutumları, kurumların değişim programlarının başarıyla gerçekleşmesi açısından oldukça önemlidir. Bu nedenle, yöneticilerin çalışanların değişime yatkınlıkları hakkında bilgi sahibi olmaları ve bu eğilimi artıracak önlemler almaları yararlı olacaktır. Bireylerin değişime yatkınlıklarını artıracağı düşünülen önemli değişkenlerden biri psikolojik güçlendirmedir. Çalışanların psikolojik güçlendirme algılarının, onların değişime yatkınlıkları üzerindeki etkilerini test etmek amacıyla yapılan bu araştırma, İstanbul’da farklı sektörlerde görev yapan 256 kişiden veri toplanarak gerçekleştirilmiştir. Analizler sonucunda, varsayıldığı üzere, katılımcıların işlerini yaparken hissettikleri “anlamlılık” düzeyi arttıkça, “değişime destek verme” ve “değişime katılma” düzeylerinin arttığı saptanmıştır. Buna ilave olarak katılımcılar, iş sonuçları üzerinde etkileri olduğunu algıladıklarında, örgütlerinde yaşanan değişimlere katılımları da artmaktadır. Araştırmada ayrıca, üst düzey yöneticiler ile çalışma süresi 10-15 yıl arasında olanlarda“anlamlılık ve etki” düzeylerinin; 6-10 yıl arası çalışma süresine sahip olan katılımcılarda ise “özerklik” düzeyinin, diğer gruplara kıyasla daha yüksek olduğu belirlenmiştir. Buna karşılık, alt kademe yöneticilerde “anlamlılık ve yeterlilik”; yönetici olmayan personelde ise “değişime katılma” boyutlarının, diğer gruplara kıyasla, anlamlı düzeyde düşük olduğu tespit edilmiştir.

Dry Mixes Based on Zeolite-Containing Rocks
Authors: Chumakova Olga Vyacheslavovna
Published: May 2019

There is a significant lag in the manufacture of dry plaster and masonry mixtures. One of the reasons constraining this process is the insufficient use of local raw materials and waste of various industries by enterprises of the regions. Experience in the development of zeolite deposits in Russia shows that the exploitation of deposits focused on the use of zeolite-bearing rocks only in traditional areas (agriculture, ecology, sorbents, etc.) with small volumes of production is not enough successful and economically justified. The efficiency of operation of deposits is determined by numerous factors, including the complex use of zeolite-containing rocks. Given that all zeolite-containing rocks can have practical application, it is advisable to provide for the operation of the field of raw materials in the form of an industrial metropolis with the production of a wide range of products.
Compositions Based on Nanosized Powders Carbides of Tungsten and Titanium, Obtained by the Method Self-Propagating High Temperature Synthesis for the Modification of Gray Cast Iron and Steel 110g13L
Authors: Leontiev Mikhail Georgievich
Published: May 2019

Iron-based alloys (steel and cast iron) are currently the main structural materials that provide a high level of mechanical and technological properties along with a relatively low cost. Increasing the performance characteristics (tensile strength, hardness, wear resistance, corrosion resistance and, ultimately, service life) of cast irons and steels is an urgent task. The quality of castings made of cast iron and steel depends on many technological parameters that affect the processes of crystallization of the melt (casting temperature, molding mixture, chemical composition, volume of casting, overheating of the metal during smelting, etc.). It is possible to improve the quality of castings without changing the technology of smelting and pouring metal into molds, if you learn how to manage the crystallization process. The laboratories have grown defect – free iron crystals with a tensile strength of more than 1000 kg/m2 (strength of carbon steel-40 kg/m2). Attempts to improve the mechanical properties by creating a single crystal are not justified, so you have to go the opposite way-to influence the crystallization process to get a lot of small crystals (grains), which also allows you to achieve high mechanical properties. The dependence of the strength characteristics on the grain size is well described by the law of Hall-Petch, according to which when the average grain size is reduced by 3...5 times there is an increase in the hardness of the material, with a further decrease in the average grain size by more than 10 times – an increase in plasticity. Influence on the processes of crystallization of iron and steel melts (change the size of metal grains, change the shape, size and distribution of graphite inclusions) can be the introduction of small additives substances (modifiers), not chemically interacting with the matrix. The use of modifiers to increase the rate of crystallization, reduce the structural heterogeneity of castings has good prospects. In addition, unlike doping, modification does not require a large number of expensive additives and, accordingly, slightly increases the final cost of production.
A Precision B Cell–Targeted Therapeutic Approach to Autoimmunity Caused by Phosphatidylinositol 3-Kinase Pathway Dysregulation
Authors: Franks S. Elizabeth , Getahun Andrew , Cambier John C.
Published: May 2019

The inositol lipid phosphatases PTEN and SHIP-1 play a crucial role in maintaining B cell anergy and are reduced in expression in B cells from systemic lupus erythematosus and type 1 diabetes patients, consequent to aberrant regulation by miRNA-7 and 155. With an eye toward eventual use in precision medicine therapeutic approaches in autoimmunity, we explored the ability of p110δ inhibition to compensate for PI3K pathway dysregulation in mouse models of autoimmunity. Low dosages of the p110δ inhibitor idelalisib, which spare the ability to mount an immune response to exogenous immunogens, are able to block the development of autoimmunity driven by compromised PI3K pathway regulation resultant from acutely induced B cell–targeted haploinsufficiency of PTEN and SHIP-1. These conditions do not block autoimmunity driven by B cell loss of the regulatory tyrosine phosphatase SHP-1. Finally, we show that B cells in NOD mice express reduced PTEN, and low-dosage p110δ inhibitor therapy blocks disease progression in this model of type 1 diabetes. These studies may aid in the development of precision treatments that act by enforcing PI3K pathway regulation in patients carrying specific risk alleles.
Structure and Peptidome of the Bat MHC Class I Molecule Reveal a Novel Mechanism Leading to High-Affinity Peptide Binding

Published: May 2019

Bats are natural reservoir hosts, harboring more than 100 viruses, some of which are lethal to humans. The asymptomatic coexistence with viruses is thought to be connected to the unique immune system of bats. MHC class I (MHC I) presentation is closely related to cytotoxic lymphocyte immunity, which plays an important role in viral resistance. To investigate the characteristics of MHC I presentation in bats, the crystal structures of peptide–MHC I complexes of Pteropus alecto, Ptal-N*01:01/HEV-1 (DFANTFLP) and Ptal-N*01:01/HEV-2 (DYINTNLVP), and two related mutants, Ptal-N*01:01/HEV-1PΩL (DFANTFLL) and Ptal-N*01:01ΔMDL/HEV-1, were determined. Through structural analysis, we found that Ptal-N*01:01 had a multi-Ala–assembled pocket B and a flexible hydrophobic pocket F, which could accommodate variable anchor residues and allow Ptal-N*01:01 to bind numerous peptides. Three sequential amino acids, Met, Asp, and Leu, absent from the α1 domain of the H chain in other mammals, were present in this domain in the bat. Upon deleting these amino acids and determining the structure in p/Ptal-N*01:01ΔMDL/HEV-1, we found they helped form an extra salt-bridge chain between the H chain and the N-terminal aspartic acid of the peptide. By introducing an MHC I random peptide library for de novo liquid chromatography–tandem mass spectrometry analysis, we found that this insertion module, present in all types of bats, can promote MHC I presentation of peptides with high affinity during the peptide exchange process. This study will help us better understand how bat MHC I presents high-affinity peptides from an extensive binding peptidome and provides a foundation to understand the cellular immunity of bats.
Bilateral Strength Asymmetries and Unilateral Strength Imbalance: Predicting Ankle Injury When Considered With Higher Body Mass in US Special Forcesa
Authors: Eagle Shawn R. , Kessels Marijn , Johnson Caleb D. , Nijst Branco , Lovalekar Mita , Krajewski Kellen , Flanagan Shawn D. , Nindl Bradley C. , Connaboy Chris
Published: May 2019

Context

Ankle injury is one of the most common conditions in athletics and military activities. Strength asymmetry (SA) and imbalance may represent a risk factor for injury, but past investigations have produced ambiguous conclusions. Perhaps one explanation for this ambiguity is the fact that these authors used univariate models to predict injury.

Objective

To evaluate the predictive utility of SA and imbalance calculations for ankle injury in univariate and multivariate prediction models.

Design

Prospective cohort study.

Setting

Laboratory.

Patients or Other Participants

A total of 140 male US Air Force Special Forces.

Main Outcome Measure(s)

Baseline testing consisted of body composition, isometric strength, and aerobic and anaerobic capacity. A clinician conducted medical chart reviews 365 days posttesting to document the incidence of ankle injury. Strength asymmetries were calculated based on the equations most prevalent in the literature along with known physiological predictors of injury in the military: age, height, weight, body composition, and aerobic capacity. Simple logistic regression was conducted using each predictor, and backward stepwise logistic regression was conducted with each equation method and the physiological predictors entered initially into the model.

Results

Strength asymmetry or imbalance or both, as a univariate predictor, was not able to predict ankle injury 365 days posttesting. Body mass (P = .01) and body mass index (P = .01) significantly predicted ankle injury. Strength asymmetry or imbalance or both significantly predicted ankle injury when considered with body mass (P = .002–.008).

Conclusions

As a univariate predictor, SA did not predict ankle injury. However, SA contributed significantly to predicting ankle injury in a multivariate model using body mass. Interpreting SA and imbalance in the presence of other physiological variables can help elucidate the risk of ankle injury.
The Wise Merchant
Authors: Barlaeus  , Post Anna-Luna , Vermeulen Corinna
Published: May 2019

On 9 January 1632, at the inauguration of the Amsterdam Illustrious School - the predecessor of the city's university - Caspar Barlaeus delivered a speech that has continued to arouse the curiosity of researchers and the general public alike: Mercator sapiens. This famous oration on the wise merchant is now considered a key text of the Dutch Golden Age. At the same time it is surrounded by misunderstandings regarding Barlaeus himself, the nascent Illustrious School and Amsterdam's merchant culture. This volume presents the first English translation and the first critical edition of the Mercator sapiens, preceded by an introduction providing historical context and a fresh interpretation of this intriguing text.
Communicate as a Professional

Published: May 2019

Across a wide range of programs in international higher education, students prepare themselves for a career in their professional field. Learning how to communicate as a professional is an essential part of that preparation. In order to carry out their communication tasks, professionals must possess a large repertoire of knowledge and skills. They also must be able to decide what best suits the situation and the goals they want to achieve. Already during their training, students come across a variety of communication tasks that are largely new to them. For these tasks, too, they need a broad knowledge and skills repertoire from which they can make the right choices.

'Communicate as a Professional' offers a solid foundation for students to develop the communication knowledge and skills they need, both when working as a professional after they have graduated and when following an educational program that prepares them for this future.
Beijing Garbage
Authors: Landsberger Stefan
Published: May 2019

Why do central and local government initiatives aiming to curb the proliferation of garbage in Beijing and its disposal continue to be unsuccessful? Is the Uberization of waste picking through online-to-offline (O2O) garbage retrieval companies able to decrease waste and improve the lives of waste pickers? Most citizens of Beijing are well aware of the fact that their city is besieged by waste. Yet instead of taking individual action, they sit and wait for the governments at various levels to tell them what to do. And even if/when they adopt a proactive position, this does not last. Official education drives targeting the consumers are organized regularly and with modest success, but real solutions are not forthcoming. Various environmental non-governmental organizations are at work to raise the level of consciousness of the population, to change individual attitudes towards wasteful behavior, but seemingly with little overall effects.
Games and Game Playing in European Art and Literature, 16th-17th Centuries
Authors: O'Bryan Robin , Lebens Naomi , Herrold Megan , Chovanec Kevin , Rocco Patricia , Packard Bethany , Kaethler Mark , Guidicini Giovanna , Sundin Greger
Published: May 2019

This collection of essays examines the vogue for games and game playing as expressed in art and literature in sixteenth- and seventeenth-century Europe. Focusing on games as a leitmotif of creative expression, these scholarly inquiries are framed as a response to two main questions: how were games used to convey special meanings in art and literature, and how did games speak to greater issues in European society? In chapters dealing with chess, playing cards, board games, dice, gambling, and outdoor and sportive games, essayists show how games were used by artists, writers, game makers and collectors, in the service of love and war, didactic and moralistic instruction, commercial enterprise, politics and diplomacy, and assertions of civic and personal identity. Offering innovative iconographical and literary interpretations, their analyses reveal how games“played, written about, illustrated and collected“functioned as metaphors for a host of broader cultural issues related to gender relations and feminine power, class distinctions and status, ethical and sexual comportment, philosophical and religious ideas, and conditions of the mind.
Modelling the effect of condensed-phase diffusion on the homogeneous nucleation of ice in supercooled water
Authors: Fowler Kathryn , Connolly Paul , Topping David
Published: May 2019

Abstract. In-situ studies of low temperature cirrus clouds have found unexpectedly low ice crystal numbers and consistently high supersaturations, which suggest that our understanding of the freezing mechanisms under these conditions are incomplete. Computational models typically use homogeneous nucleation to predict the ice nucleated in supercooled water. However, the existence of ultra-viscous organic aerosol in the upper troposphere has offered alternative ice nucleation pathways, which have been observed in laboratory studies. The possible effects of aerosol viscosity on cloud micro-physical properties have traditionally been interpreted from simple model simulations of an individual aerosol particle based on equilibration timescales. In this study, to gain insight into the formation of ice in low temperature cirrus clouds, we have developed the first cloud parcel model with bin micro-physics to simulate condensed phase diffusion through each individual aerosol particle. Our findings demonstrate, for the first time, the complex relationship between the rate of ice formation and the viscosity of secondary organic aerosol, driven by two competing effects – which cannot be explained using existing modelling approaches. The first is inhibition of homogeneous ice nucleation below 200 K, due to restricted particle growth and low water volume. The second occurs at temperatures between 200 K and 220 K, where water molecules are slightly more mobile and a layer of water condenses on the outside of the particle, causing an increase in the number of frozen aerosol particles. Our new model provides a basis to better understand and simulate cirrus cloud formation on a larger scale, addressing a major source of uncertainty in climate modelling through the representation of cloud processes.

Para ello se hará uso del método de análisis marxista dado que aporta las mejores herramientas para atender a una perspectiva de clase.
Las cooperativas de mujeres en España: ¿empoderamiento o perpetuación de roles de género?
Authors: Gómez Carrasco Itzíar
Published: May 2019

Este artículo presenta la experiencia de tres cooperativas dirigidas por mujeres en Andalucía (España) para ilustrar un contexto del sur de Europa donde el alto nivel desempleo y las políticas de austeridad han aumentado la importancia de las empresas sociales. Estas cooperativas se desarrollaron después de la crisis económica de 2008, en un contexto marcado por necesidades sociales emergentes, junto con recortes presupuestarios y cambios en las políticas sociales que afectaron particularmente a los países del sur de Europa. A las mujeres que fundaron estas cooperativas les atrajo un modelo empresarial que colocaba a las personas antes del capital para lograr objetivos sociales, junto con el objetivo económico de asegurar los medios de subsistencia de sus socias. Al discutir el concepto de empoderamiento de Kabeer, este artículo explora cómo, en el contexto andaluz, el modelo cooperativo permite a las mujeres mejorar sus condiciones de vida en general, creando empleos que se adaptan mejor a sus necesidades, mejorando su autoestima y fortaleciendo su sentido de empoderamiento, proporcionándoles a la vez las condiciones necesarias para una mayor flexibilidad y conciliación familiar. Sin embargo, dada la relativa ausencia de oportunidades alternativas, la búsqueda de flexibilidad de las mujeres y el predominio de su misión social por encima de fines lucrativos, también sugiere que el riesgo de perpetuar ciertos roles de género tradicionales permanece.
Evaluar y promover las competencias para el emprendimiento social en las asignaturas universitarias
Authors: Velasco Martínez Leticia Concepción , Estrada Vidal Ligia Isabel , Pabón Figueras Manuela , Tójar Hurtado Juan Carlos
Published: May 2019

Las universidades, así como diversas entidades científicas y académicas, tanto a nivel nacional como internacional, han tomado conciencia de la necesidad de promover el emprendimiento en el ámbito universitario (UNESCO, 2009; Guerrero, Urbano, Ramos, Ruiz-Navarro, Neira y Fernández-Laviada, 2016). En este trabajo se presenta una herramienta que resulta útil para evaluar las competencias para el emprendimiento social en cualquier asignatura universitaria. Se han realizado dos versiones de la herramienta (estudiantes y profesorado) que permiten analizar y valorar el grado en que dichas competencias se trabajan en una asignatura concreta. Además, la versión del docente está diseñada para promover la reflexión en el profesorado sobre el margen de mejora de las competencias emprendedoras y favorecer la puesta en práctica de propuestas concretas para integrarlas en las asignaturas a corto plazo. La herramienta, en sus dos versiones, denominada “Registro para Evaluar el Emprendimiento Social en las Aulas Universitarias (RESAU)”, ha sido validada por 14 expertos. En la versión de estudiantes se realizó una validación estadística empleándose una muestra piloto de estudiantes de Ciencias Económicas y de Ciencias de la Educación (n = 180), de las Universidades de Granada, Málaga y Sevilla. En el caso de la versión de los estudiantes, la herramienta muestra en qué medida las competencias para el emprendimiento social se trabajan en las actividades de aula. En la versión del profesorado, la herramienta ilustra adecuadamente aquellas competencias para el emprendimiento social que son trabajadas en cada asignatura, y las que poseen un margen de mejora que puede ser desarrollado por cada docente universitario. Las conclusiones del estudio destacan la relevancia de trabajar las competencias para el emprendimiento social en las aulas universitarias y ponen de relieve la manera en que cada docente plantea estrategias de mejora.
Comunicación retórica en las crónicas del siglo XVI. Escritura normativa en las "Repúblicas del mundo" de Fray Jerónimo Román Zamora
Authors: Cuautle Aguilar Marcos Santiago
Published: May 2019

El agustino Jerónimo Román Zamora publicó en 1575 Repúblicas del mundo, una crónica que “describe” leyes, usos y costumbres esenciales de civilizaciones inspiradas por una “luz natural” que permitía a los hombres vivir en compañía de los demás. Inscrita en la tradición retórica española del Antiguo Régimen que juzga en lo moral los acontecimientos pasados, carece de alguna pretensión etnográfica. El rétor persuade a su interlocutor del deber de distinguir entre las cualidades y prácticas de gobierno que reproducen la ejemplaridad de aquellas dañinas. Un preliminar abordaje teórico analiza de qué manera los lectores comprendían las descripciones históricas y cómo respondían a una forma específica de entender al destinatario además del texto en sí mismo. Se analizan las condiciones comunicativas que hicieron posible la construcción de una cultura sustentada en andamiajes normativos.
Pólis y política: M. Heidegger y H. Arendt
Authors: Álvarez Yágüez Jorge
Published: May 2019

Se analiza en primer lugar el enlace que Heidegger realiza entre pólis y política para a continuación observar el juego de esas categorías en H. Arendt y la crítica que supone del que fuera su maestro. La gran oposición entre ambos radica en la distinta perspectiva de análisis, ontológica en un caso y estrictamente política en otro. Se observa finalmente, cómo, a pesar de la certera crítica de Arendt, cierta transformación del enfoque heideggeriano podría proporcionarnos un valioso potencial crítico más necesario que nunca en nuestra crisis epocal.

Published: May 2019

A field experiment was carried out on sandy soil at Ismailia Governorate during two consecutive seasons of 2017-2018 under dripping irrigation system to study the effect of applied volcanic ash and magnetite mineral alone or mixture compared to recommended fertilizers (chemical fertilizers) as control on soil properties, peanut yield and its quality.The obtained results show that soil salinity, pH and soil bulk density were decreased in volcanic ash, magnetite mineral and volcanic ash + magnetite mineral combined treatments, as compared to the control one. The total porosity and water holding capacity (WHC) values were augmented when soil treated by volcanic ash, magnetite mineral and volcanic ash + magnetite mineral, as compared to control. In addition, Hay and pod dry weight were significantly increased with combined treatment 26.40 and 65.00 %, respectively over the control treatment. The NPK contents were augmented due to the application of volcanic ash; it also amplified zinc concentration in hay four times and in seed three times that of control treatment. Manganese concentration followed the same trend of Zn concentration. Iron concentration increased almost five and four times compared with control treatment in hay and seed. Cupper concentration increased by 30 and 70 % in comparison to control treatment in hay and peanut seed, respectively due to volcanic ash application. The highest values of net photosynthesis rate as well as water use efficiency were also obtained from volcanic ash + magnetite mineral combined treatment as compared to those under control plants. The mixture of volcanic ash with magnetite mineral realized the highest oil content and total amino acids. Anatomical studies revealed significant increase in leaf features represented in midrib thickness, length and width of vascular bundle, phloem and xylem tissues and number of xylem vessels in vascular bundle as well as the leaf blade thickness compared to control plants. Combination of volcanic ash with magnetite mineral gave the maximum net profit as compared to control treatment. The agronomic efficiency could be arranged in the following descending order of volcanic ash plus magnetite mineral, > volcanic ash, > magnetite mineral, and finally > control.

Use of experimental gillnet fleets is common both in scientific studies of fish populations and in fishsampling for management purposes. Fish catchability may vary considerably with fish and gillnet meshsize, and catches obtained by gillnet fleets composed of nets with different mesh sizes may give lengthand age distributions that deviate considerably from the length and age structure of the population.We have estimated the absolute catchability of allopatric brown trout (Salmo trutta) in the littoral andpelagic habitat of a small lake based on a mark-recapture experiment. The brown trout catchabilityvaried considerably both with fish size and habitat type, probably due to a size-related variation inswimming distance per time unit and a size-related use of the different lentic habitats. The samplingbias in experimental gillnet fishing may be reduced by operating the gillnet fleets in all possible lentichabitats and most fundamentally, by use of catchability data obtained from populations with ‘known’length and age structures. By reducing this sampling bias, more realistic estimations of the age andlength distribution for a given population will be possible.
Remembrance: A Husserlian Phenomenology of Sufi Practice
Authors: Applebaum Marc
Published: May 2019

The study seeks to answer the phenomenological question: What in essence is religious experience—specifically, the lived experience of “remembrance” (dhikr) in Sufi practice within the schools of Sufism shaped by the “Greatest Master,” Ibn al-'Arabi? The eidetic structure of remembrance is the awakening of the individuated human subject to recollecting the primordial ground of his or her identity as a dynamic instantiation of the Absolute. This is simultaneously experienced as the subject becoming the object of remembrance—that is, being remembered by the Absolute. This transforms the psychological ego's relationship to its own embodied, affective, and cognitive living, as the “center of gravity” of that ego shifts from an egocentric one—that is, an identification with the natural attitude standpoint of the personal ego—to progressively greater centeredness in the transcendental ego as a locus of ongoing world constitution and primordial self-presence, while nevertheless living as a unique individual.

Students in Indonesia have been cutting classes for some time now and it has become a bad habit. They leave their house toward their educational institutions, either school or college, but in fact, they go somewhere else. The issue was supported by the lack of communication between the schools and parents related to the student attendance. Dealing with the problems mentioned above, it is required to create a Telegram Messenger application for student presence as a solution. Application-based student presence Telegram Messenger was made to ensure that students attend classes, by steps as follow: firstly, students must hand in the ID card to the teacher on duty, then the teacher will tap the card, and finally the data will be recorded and be saved in the database automatically. The data will be saved automatically every day, and then it will be sent personally to their parents who had their mobile phones registered to receive information regarding their children presence at school on the particular date and hour. In addition, this application provides service for the parents to find the information on daily and monthly basis. This application can also be a part of consideration in decision making for the principals by downloading student attendance data in Microsoft Excel file format. The implementation of the applications based on Telegram Messenger for students’ presence at school was expected to be a solution for the problems of student absence due to skipping school. This application has been tested in SMK Unggulan Terpadu PGII Bandung with very satisfying results and the level of student absence was able to be fixed.

Continuation of the mycological study of the fire-damaged pine forest in Kampinos National Park in central Poland in 2017 produced interesting new findings. Among the taxa collected, 36 were new to the park, six had not been hitherto reported from Poland (Calycellina araneocincta, Ciliolarina aff. laetifica, Clitocybe metachroides, Galerina cerina f. longicystis, Parasola cuniculorum, Pleonectria pinicola), and the previous status of one taxon (Pleonectria cucurbitula) had been uncertain. Short descriptions based on collected specimens have been prepared for all taxa new to Poland. The current number of taxa of macromycetes identified in Kampinos National Park has reached 1,604.
Insegnare e apprendere la lingua seconda nel contesto migratorio. Il caso dell’Italia
Authors: Silva Clara
Published: May 2019

A Itália é um país tradicionalmente marcado por fenômenos de bilinguismo e plurilinguismo. A atenção sobre eles vem crescendo nos últimos trinta anos, uma vez que o aumento da presença de filhos e filhas de imigrantes na escola tem revelado suas necessidades específicas, incluindo aquelas relacionadas ao aprendizado da língua italiana. O presente artigo reconstrói, grosso modo, os resultados dos estudos lingüísticos, focalizando as coordenadas gerais dentro das quais o tema do ensino e aprendizagem do italiano como segunda língua é colocado. O artigo enfoca algumas questões cruciais em torno das quais a pragmática intercultural se desenvolve, incluindo a interlíngua, a transferência, a distância entre a primeira e a segunda língua e os fatores psicossociais que interferem no aprendizado da segunda língua. O objetivo é mostrar como a questão da aprendizagem da língua do país de imigração está ligada não apenas a fatores estritamente lingüísticos, mas também biográficos.

Este estudo teve por objetivo avaliar a associação entre o consumo de glúten e o hábito intestinal de crianças e adolescentes com transtorno do espectro autista. Para tanto, foi realizado um estudo transversal com 30 pessoas com transtorno do espectro autista com idade entre 10 e 18 anos. O consumo de glúten foi avaliado por meio da aplicação de um questionário de frequência alimentar e o hábito intestinal foi avaliado por meio da escala de Bristol. A maioria dos participantes consumia alimentos que contêm glúten. Quase metade dos participantes (46,6%) apresentou constipação ou diarreia e não houve associação entre o hábito intestinal e a frequência do consumo de alimentos que contêm glúten. Assim, o presente estudo não apresentou resultados que confirmem a relação entre o consumo de glúten e o hábito intestinal de crianças e adolescentes com transtorno do espectro autista.

Este estudo objetivou determinar o perfil entomológico da doença de Chagas em áreas rurais e periurbanas de Potengi – CE e a infecção de triatomíneos pelo Trypanosoma cruzi. Dados secundários foram obtidos da 20ª Coordenadoria Regional de Saúde do Programa de Controle da Doença de Chagas, oriundos de buscas ativas dos Agentes de Combate às Endemias realizadas entre 2013 a 2015. Verificou-se que 69,23% dos domicílios pesquisados encontravam-se infestados por triatomíneos, sendo 1.150 exemplares capturados no peridomicílio e 145 no intradomicílio. Triatoma pseudomaculata, T. brasiliensis, Panstrongylus lutzi e Rhodnius nasutus foram identificadas, sendo T. pseudomaculata com maior prevalência, seguida por T. brasiliensis. Dentre os triatomíneos capturados 1,34% estavam infectados com Trypanosoma cruzi, dos quais Triatoma pseudomaculata teve maior representatividade de infecção. A infestação triatomínica em residências e anexos no município de Potengi demonstra colonização por estes insetos e adaptação ao ambiente doméstico, sendo necessárias melhorias na vigilância epidemiológica e controle desses vetores.

Introdução: A tuberculose é uma doença infecciosa crônica cujo agente etiológico são bacilos da bactéria Mycobacterium tuberculosis. O Brasil notificou quase 70 mil casos novos de tuberculose em 2014, e essa elevada incidência fez com que o mesmo ocupe a 16ª posição em número de casos entre os 22 países de alta carga da doença. Objetivo: Verificar a prevalência de casos notificados de tuberculose em idosos, no Rio Grande do Sul, no período de 2012 a 2017. Métodos: Pesquisa descritiva, utilizando dados da Tabulação da Vigilância epidemiológica com a opção “Tuberculose”. Em “Linha” marcou-se o “Regional notificação”, em “Coluna” foi selecionada a “Faixa etária” e em “Conteúdo” a “Frequência”. Como “Períodos disponíveis” foram selecionados isoladamente os anos de 2012 a 2017. Na “Faixa etária” foram selecionados os itens “60 a 69 anos”, “70 a 79 anos” e “80 anos e mais”. Para a discriminação de sexo selecionou-se os itens “Masculino” e “Feminino”. Resultados: Entre os casos de tuberculose foram encontrados 3122 idosos entre 60 e 69 anos, 1443 nos de 70 a 79 anos e 570 em 80 anos ou mais. Houve um predomínio do sexo masculino entre os infectados. Conclusão: Observou-se alta prevalência de notificação de tuberculose nos idosos. Espera-se que este conhecimento possa subsidiar dados para a elaboração de políticas públicas para esta população, propiciando uma menor incidência desta doença e seus agravos.
