Resumen:Antecedentes y Objetivos: El género Thelephora pertenece a Thelephoraceae, Thelephorales, Agaricomycetes, Basidiomycota y corresponde a hongos ectomicorrizógenos, de los que se conocen al menos 50 especies alrededor del mundo. De ellas, 28 se encuentran en ecosistemas tropicales y subtropicales; no obstante, se considera que han sido escasamente estudiadas en los trópicos. Por consiguiente, el objetivo de este trabajo consistió en contribuir al conocimiento de los teleforáceos tropicales presentes en una zona relativamente no explorada desde el punto de vista micológico en México, como lo es el estado de Yucatán.Métodos: La recolecta se realizó en una selva mediana subcaducifolia al sur del estado de Yucatán, en el municipio Tekax, durante la temporada de lluvias de agosto-diciembre 2017 y de junio-agosto 2018. El material revisado se caracterizó macromorfológicamente a partir de ejemplares frescos, y micromorfológicamente mediante la observación al microscopio óptico de los basidiomas. Los ejemplares se encuentran depositados en los herbarios IBUG y UADY.Resultados clave: Thelephora dominicana solo se conocía de República Dominicana, por lo cual este registro amplía su rango de distribución. Se comenta su potencial asociación ecológica con especies de Fabaceae y Polygonaceae, en particular con Coccoloba spp. y Gymnopodium floribundum. Para México, únicamente se habían registrado nueve especies de este género. Thelephora dominicana constituye la décima especie mexicana y la séptima procedente del neotrópico mexicano. Para la península de Yucatán se conocía T. cervicornis, por lo que es la segunda especie en reportarse para la región.Conclusiones: Se reporta por primera vez para la micobiota mexicana a Thelephora dominicana y por segunda ocasión a nivel mundial.Palabras clave: Agaricomycotina, península de Yucatán, selva mediana subcaducifolia, taxonomía.Abstract:Background and Aims: The genus Thelephora belongs to Thelephoraceae, Thelephorales, Agaricomycetes, Basidiomycota, and corresponds to ectomycorrhizal macrofungi, with at least 50 species known around the world. Of these, 28 are found in tropical and subtropical ecosystems. Nevertheless, it is considered they are poorly known in the tropics. Therefore, the objective of this work was to contribute to the knowledge of tropical thelephoraceous fungi present in an area relatively unexplored in Mexico from the mycological point of view, such as the Yucatán state.Methods: Collections were made in a subdeciduous seasonal dry forest in the south of the Yucatán state, in Tekax municipality, during the rainy season of August-December 2017 and June-August 2018. All the material was examined using macromorphological data from fresh specimens, and micromorphologically by basidiomata sections observed with the optical microscope. The specimens are deposited in the herbaria IBUG and UADY.Key results: Thelephora dominicana was only known from Dominican Republic, hence this record increases its distribution range. Moreover, we report its potential association with species of Fabaceae and Polygonaceae families, such as Coccoloba spp. and Gymnopodium floribundum. In Mexico, only nine species were previously reported in Thelephora, T. dominicana being the tenth one and the seventh for the Mexican Neotropical region. From the Yucatán peninsula, T. cervicornis was the only known species of this genus, thus this is the second one from this area.Conclusions: This is the first report of T. dominicana for Mexico and the second time worldwide. Key words: Agaricomycotina, subdeciduous seasonal dry forest, taxonomy, Yucatán peninsula.

This paper deals with three different perspectives appeared in foreign visitors’ records on Korea in 1900s. Jack London was a writer who wrote novels highly critical of American society based on progressivism. However, when his progressive perspective was adopted to report the political situation of Korea in 1904, he revealed a typical perspective of orientalism. He regarded Korea and ways of living in Korea as disgusting and ‘uncivilized.’Compared with Jack London’s perspective, French poet Georges Ducrocq’s book was rather favorable. He visited Korea in 1901 and he showed affectionate attitude toward Korea and its people. However, his travel report, Pauvre et Douce Coree, can be defined as representing aesthetic orientalism. He tried to make all the ‘Korean things’ seem beautiful and nice, but it is true that this kind of view can also conceal something concrete and specific. This perspective at once beautifies Korea and also conceals the reality about Korea.E. Burton Holmes was a traveler and he often used his ‘motion-picture’ machine to record things he witnessed while travelling around worldwide countries. So, his report (travelogue) and motion picture film on Korea written and made in 1901 was based on close observation and rather objective point of view. Nonetheless, he couldn’t avoid the perspective of the colonizer’s model of the world, in other words, geographical diffusionism of western culture.

AbstractStarting from the quantitative reconstruction of revenues and expenses of the Royal Treasury in the Yucatan province during the period 1801-1821, the paper shows the transition from an unbalanced regional fiscal structure that depended on colonial transfers (situados) to offset the deficit, to one self-sufficient structure in the context of the Independence War and the liberalism of the Cortes de Cadiz. An autonomy based on the indigenous capitation tax and the fiscal control of foreign trade that was made in the ports of the Yucatan Peninsula.

It is only the comprehension of Islamic in the legislation in the world that it encompasses the change, evolution or developments being made in different areas of life to accommodate the changes   inegislation or to address the changes, Islamic jurists laid down different principles of fiqah.one of these principle is sad u-zaraey which is known as the “prohibition of evasive legal devices”. As difference in opinion is also existing in all the areas of life, similarly difference of opinions is existing among the Islamic jurists in describing this principle as well. One of the jurists who are possessing the counter narrative of sad u-zaraey is ibn e hazam. In this article research has been made in order to elaborate the ibn e hazam,s point of view about sadd u zaraey and also the vice versa opinion of other jusrists. It is also discussed with example that how the principle of sad u-zaraey is important in Islamic legislation.

AbstractCassava (Manihot esculenta Crantz) is one of the most important staple crops for small farmers in the tropics, feeding about 800 million people worldwide. It is currently cultivated in South and Central America, Africa and Asia. The genus Vatiga is widespread throughout the Neotropical region. Its species are sympatric and feed exclusively on cassava. The main objectives of this paper are: (1) to assess the potential distribution of Vatiga, one of the most relevant pests of cassava; (2) to project the resulting models onto the world; (3) to recognize areas with suitable and optimal climates (and thus, high probability) for future colonization, and (4) to compare this model with the harvested area of cassava analyzing the climatic variables required by both the host and the pest species. Species distribution models were built using Maxent (v3.3.3k) with bioclimatic variables from the WorldClim database in 2.5 arc min resolution across the globe. Our model shows that Vatiga has the potential to expand its current distribution into other suitable areas, and could invade other regions where cassava is already cultivated, e.g., Central Africa and Asia. Considering the results and the high host specificity of Vatiga, its recent appearance in Réunion Island (Africa) poses a serious threat, as nearby areas are potentially suitable for invasion and could serve as dispersal routes enabling Vatiga to reach the continent. The present work may help prevention or early detection of Vatiga spp. in areas where cassava is grown.

Broad Scale

The distributions of birds during migratory stopovers are influenced by a hierarchy of factors. For example, in temperate regions, migrants are concentrated near areas of bright artificial light at night (ALAN) and also the coastlines of large water bodies at broad spatial scales. However, less is known about what drives broad-scale stopover distributions in the tropics. We quantified seasonal densities of nocturnally migrating landbirds during spring and fall of 2011–2015, using two weather radars on the Yucatan peninsula, Mexico (Sabancuy and Cancun). We tested the influence of environmental predictors in explaining broad-scale bird stopover densities. We predicted higher densities in areas (1) closer to the coast in the fall and farther away in spring and (2) closer to bright ALAN and with lower ALAN intensity in both seasons. We found that birds were more concentrated near the coastline in the fall and away from it in spring around Cancun but not Sabancuy. Counter to our expectations, we detected increased bird densities with increased distance from lights in spring around Sabancuy, and in both seasons around Cancun, suggesting avoidance of bright areas during those seasons. This is the first evidence of broad-scale bird avoidance of bright areas during stopover.

In this paper attempt will be made in explaining some basic notions of Simmel's sociology, especially those regarding his very complex comprehension of money and causality in history. In analysis of his work, I will argue that Simmel stands very close to the contemporary structurational point of view, and that there are three levels of freedom and structural givens (overlapping each other) in society. These are: meta-theoretical level, level of integration into the World, and the historical level. Besides that, less explicit aims of this paper are to show that in Simmlel's thought there are no disciplinary borders between sociology and philosophy, as well as to depict some of the potential benefits that sociology might get from this line of reasoning.

Reading Texts

When readers understand a text they construct a mental representation of the text. This text representation contains not only the information that is explicitly expressed in the text, but also information that is inferred by the readers during reading. A text representation can be described in terms of relations between the elements in the representation, but also in terms of relations of the representation with (a model of) the world. For example, readers can determine whether a particular sentence is logically consistent with the text, as well as whether it is true or false, whether it is plausible or possible, or whether it is completely new for her or him. The distinction between relations within the structure of the text representation and relations that refer to the world has hardly ever been made in empirical research on inferences. In general inferences have been investigated from the point of view of their contribution to the coherence of the representation. The consequence is that the question whether inferences are made during reading has generally been answered in terms of the internal coherence of the representation: Inferences that contribute to the coherence of the representation are made during reading, other inferences are not. The central question in the present research is to what extent inference processes are determined by the relations of the inferences with a model of the world and, accordingly, to what extent inference processes are determined by the reader's knowledge of the world. Experiments are discussed on inferences that contribute to the coherence of the representation and, accordingly, are supposed to be made during reading. In this research the knowledge of the reader with respect to the topic of the text was varied by having expert economists and non-experts reading texts on economics. The results indicate that the prevalent conclusion with respect to inferences is an overgeneralisation. It was demonstrated that inference processes are controlled by the reader's knowledge.
