Sich erlaufen. Pilgern als Identitätsstärkung

Against the background of an unexpected upswing in pilgrimages, this article states the thesis that pilgrimage enables a strengthening of one’s identity. In addition, the problem of a fragmented and indefinite identity is sketched, with reference to Zygmunt Bauman. In contrast stands a model of identity (connected with Albrecht Grçzinger) in which one contributes to a tradition in which one already is situated. In its main part, the article investigates the various factors of pilgrimage that contribute to this process of gaining one’s identity. Thus, a route frequented as much as theWay of St. James forms an already patterned space that offers the pilgrim traditioned roles to adopt. Walking, as a characteristic element of pilgrimage, is interpreted as physically generating and distinctively opening the space in which pilgrims understand themselves in the world. It also can be shown how walking as a form of physical being that leads from an instrumental relationship to one’s body to an immediate being in living one’s life, conveys certainty about one’s self and the world, activates one’s potential to overcome challenges, and provides self-empowerment. The author makes a strong case for a definition of pilgrimage oriented to an understanding of the hardship of crossing a foreign land, which is an image of a goal-oriented understanding of existence. The resulting poles of self-assurance and self-estrangement in pilgrimage are, in connection with Wilhelm Gräb, interpreted as an expression of a truly known but at the same time distanced self-understanding. Pilgrimage is therefore a form of physical self-interpretation in which people learn to view and be aware of their self-familiarity. Finally, against the background of this representation, criteria are elaborated for organizing a pilgrimage journey that is conducive to identity.

Identification of a new genomic hot spot of evolutionary diversification of protein function.

Establishment of phylogenetic relationships remains a challenging task because it is based on computational analysis of genomic hot spots that display species-specific sequence variations. Here, we identify a species-specific thymine-to-guanine sequence variation in the Glrb gene which gives rise to species-specific splice donor sites in the Glrb genes of mouse and bushbaby. The resulting splice insert in the receptor for the inhibitory neurotransmitter glycine (GlyR) conveys synaptic receptor clustering and specific association with a particular synaptic plasticity-related splice variant of the postsynaptic scaffold protein gephyrin. This study identifies a new genomic hot spot which contributes to phylogenetic diversification of protein function and advances our understanding of phylogenetic relationships.

The Honey Bee Pathosphere of Mongolia: European Viruses in Central Asia

Parasites and pathogens are apparent key factors for the detrimental health of managed European honey bee subspecies, Apis mellifera. Apicultural trade is arguably the main factor for the almost global distribution of most honey bee diseases, thereby increasing chances for multiple infestations/infections of regions, apiaries, colonies and even individual bees. This imposes difficulties to evaluate the effects of pathogens in isolation, thereby creating demand to survey remote areas. Here, we conducted the first comprehensive survey for 14 honey bee pathogens in Mongolia (N = 3 regions, N = 9 locations, N = 151 colonies), where honey bee colonies depend on humans to overwinter. In Mongolia, honey bees, Apis spp., are not native and colonies of European A. mellifera subspecies have been introduced ~60 years ago. Despite the high detection power and large sample size across Mongolian regions with beekeeping, the mite Acarapis woodi, the bacteria Melissococcus plutonius and Paenibacillus larvae, the microsporidian Nosema apis, Acute bee paralysis virus, Kashmir bee virus, Israeli acute paralysis virus and Lake Sinai virus strain 2 were not detected, suggesting that they are either very rare or absent. The mite Varroa destructor, Nosema ceranae and four viruses (Sacbrood virus, Black queen cell virus, Deformed wing virus (DWV) and Chronic bee paralysis virus) were found with different prevalence. Despite the positive correlation between the prevalence of V. destructor mites and DWV, some areas had only mites, but not DWV, which is most likely due to the exceptional isolation of apiaries (up to 600 km). Phylogenetic analyses of the detected viruses reveal their clustering and European origin, thereby supporting the role of trade for pathogen spread and the isolation of Mongolia from South-Asian countries. In conclusion, this survey reveals the distinctive honey bee pathosphere of Mongolia, which offers opportunities for exciting future research.

La formación de competencias digitales de estudiantes de profesorados universitarios : La estrategia de e-actividades en un modelo de aula extendida

Es un hecho que las Tecnologías de la Información y la Comunicación (TIC) han modificado nuestras prácticas sociales. También lo es que los jóvenes nacidos en los últimos años parecen haberse apropiado de ellas con gran habilidad. Sin embargo, luego de varios años enseñando TIC a alumnos de profesorados universitarios de la Facultad de Humanidades y Ciencias de la Educación (FaHCE) de la Universidad Nacional de la Plata, observamos que sus desempeños en relación a dichas tecnologías no parecía ni suficiente ni apropiado de acuerdo a los estándares internacionales y regionales vigentes de competencias digitales para el nivel universitario. Como estrategia didáctica superadora implementamos un diseño de instrucción basado en el modelo de aula extendida con e-actividades, buscando ampliar el contacto de los estudiantes con la propuesta de la asignatura, cuantitativa y cualitativamente. Luego, al haber obtenido algunas señales auspiciosas en cuanto el desarrollo de las competencias digitales de nuestros alumnos, nos formulamos la hipótesis que orientó nuestro trabajo: Las e-actividades en un modelo de aula extendida podrían favorecer el desarrollo de las competencias digitales académicas de los estudiantes de profesorados universitarios. Emprendimos entonces esta investigación que, con el objetivo principal de mejorar las competencias digitales de nuestros estudiantes, dirigimos en dos direcciones: Indagar cuáles son los niveles de conocimientos digitales deseables para un alumno futuro docente del siglo XXI. En base a la revisión documental sobre este tema, consideramos que un estudiante de profesorado universitario posee competencias digitales si, además de dominarlas, las valora y es consciente de cómo ellas contribuyen a su formación académica y de cómo seguirán haciéndolo en su desempeño profesional futuro, consciente al mismo tiempo de que las TIC no poseen un potencial transformador en sí mismas, sino en función del uso que se haga de ellas. Comprobar la veracidad de nuestra hipótesis sobre los potenciales beneficios de las e-actividades en la formación digital de nuestros estudiantes, y de verificarse este supuesto, destacar las condiciones de calidad según las cuales deberían diseñarse

The Flowchart Model of Cluster Policy: The Automobile Industry Cluster in China

This paper proposes a general model of the flowchart approach to industrial cluster policy and applies this model to Guangzhou's automobile industry cluster. The flowchart approach to industrial cluster policy is an action plan for prioritizing policy measures in a time-ordered series. We reached the following two conclusions. First,we clarified the effects of Honda, Nissan, and Toyota on agglomeration in Guangzhou's automobile industry cluster. Second, we established that local governments play a crucial role in successful industrial cluster policy, and that the mayor of the local government should be offered incentives in order to target industrial clustering and implement cluster policy.

Dealing with Semantic Heterogeneity Issues on the Web

The Semantic Web is an extension of the traditional Web in which meaning of information is well defined, thus allowing a better interaction between people and computers. To accomplish its goals, mechanisms are required to make explicit the semantics of Web resources, to be automatically processed by software agents (this semantics being described by means of online ontologies). Nevertheless, issues arise caused by the semantic heterogeneity that naturally happens on the Web, namely redundancy and ambiguity. For tackling these issues, we present an approach to discover and represent, in a non-redundant way, the intended meaning of words in Web applications, while taking into account the (often unstructured) context in which they appear. To that end, we have developed novel ontology matching, clustering, and disambiguation techniques. Our work is intended to help bridge the gap between syntax and semantics for the Semantic Web construction

A generic persistence model for CLP systems

This paper describes a model of persistence in (C)LP languages and two different and practically very useful ways to implement this model in current systems. The fundamental idea is that persistence is a characteristic of certain dynamic predicates (i.e., those which encapsulate state). The main effect of declaring a predicate persistent is that the dynamic changes made to such predicates persist from one execution to the next one. After proposing a syntax for declaring persistent predicates, a simple, file-based implementation of the concept is presented and some examples shown. An additional implementation is presented which stores persistent predicates in an external database. The abstraction of the concept of persistence from its implementation allows developing applications which can store their persistent predicates alternatively in files or databases with only a few simple changes to a declaration stating the location and modality used for persistent storage. The paper presents the model, the implementation approach in both the cases of using files and relational databases, a number of optimizations of the process (using information obtained from static global analysis and goal clustering), and performance results from an implementation of these ideas.

Models for Internal Quality Fruit Sorting, Based on Time- Domain Laser Reflectance Spectroscopy (TDRS)

Time domain laser reflectance spectroscopy (TDRS) was applied for the first time to evaluate internal fruit quality. This technique, known in medicine-related knowledge areas, has not been used before in agricultural or food research. It allows the simultaneous non-destructive measuring of two optical characteristics of the tissues: light scattering and absorption. Models to measure firmness, sugar & acid contents in kiwifruit, tomato, apple, peach, nectarine and other fruits were built using sequential statistical techniques: principal component analysis, multiple stepwise linear regression, clustering and discriminant analysis. Consistent correlations were established between the two parameters measured with TDRS, i.e. absorption & transport scattering coefficients, with chemical constituents (sugars and acids) and firmness, respectively. Classification models were built to sort fruits into three quality grades, according to their firmness, soluble solids and acidity.

Self-configuring data mining for ubiquitous computing

Ubiquitous computing software needs to be autonomous so that essential decisions such as how to configure its particular execution are self-determined. Moreover, data mining serves an important role for ubiquitous computing by providing intelligence to several types of ubiquitous computing applications. Thus, automating ubiquitous data mining is also crucial. We focus on the problem of automatically configuring the execution of a ubiquitous data mining algorithm. In our solution, we generate configuration decisions in a resource aware and context aware manner since the algorithm executes in an environment in which the context often changes and computing resources are often severely limited. We propose to analyze the execution behavior of the data mining algorithm by mining its past executions. By doing so, we discover the effects of resource and context states as well as parameter settings on the data mining quality. We argue that a classification model is appropriate for predicting the behavior of an algorithm?s execution and we concentrate on decision tree classifier. We also define taxonomy on data mining quality so that tradeoff between prediction accuracy and classification specificity of each behavior model that classifies by a different abstraction of quality, is scored for model selection. Behavior model constituents and class label transformations are formally defined and experimental validation of the proposed approach is also performed.
