Redescription of Trypanosoma siniperca Chang 1964 from freshwater fish of China based on morphological and molecular data

During the parasite fauna investigation within 2005, the freshwater fish trypanosome Trypanosoma siniperca Chang 1964 was isolated from the blood of Mandarin carp (Siniperca chuatsi) from Niushan Lake, Hubei Province, central China. Blood trypomastigotes were observed only, and the density of infection was low. Light microscopy examinations of this material made it possible to study in detail the morphology of this parasite and redescribe it according to current standards. T. siniperca is characterized also on the molecular level using the sequences of SSU rRNA gene. Phylogenetic analyses based on these sequences allowed clearer phylogenetic relationships to be established with other fish trypanosomes sequenced to date.

PLANKTON AND SESTON STRUCTURE IN A SHALLOW, EUTROPHIC SUBTROPICAL CHINESE LAKE

The seasonal dynamics in the nutrient concentrations, chlorophyll-a amount (Chl-a), total algal volume (CV), Chl-a/CV ratio, seston structure were studied at two sampling stations in a shallow, highly eutrophicated subtropic lake (the Guozheng Hu area of the East Lake) on the plain of the middle basin of the Chang Jiang (the Yangtze River) of China. The lake ecosystem of the Guozheng Hu area is dominated by two planktivorous fishes (silver carp and bighead carp), phytoplankton and zooplankton. Macrophytes are extremely scarce in this area. Concentrations of the total dissolved nitrogen and phosphorus in the Guozheng Hu area in 1990 were very high. Fish yield, of which, more than 90 % was composed of silver carp and bighead carp in the Guozheng Hu area was very high (ca. 1140 kg/ha or 45.6 g/m3 in 1990). Grazing pressure by the fishes on the plankton community is considered to be rather strong. The annual average biomass of zooplankton was ca. 1/3 - 1/2 that of phytoplankton. On the average, dry matter in the living plankton only constituted ca. 3-7 % of the total dry seston, and plankton carbon only constituted ca. 5 - 10 % of the seston carbon. The present results indicate that, in the Guozheng Hu area of the East Lake, of the organic part of the seston, detritus is quantitatively an important constituent, while living plankton is only a very small component.

序破急 Jo-Ha-Kyu: enticement - crux - consolidation. From study to learning: Process drama projects in the Japanese English language university classroom

This dissertation investigates how social issues can be explored through process drama projects in the Japanese university English as a Foreign Language classroom context. The trajectory of this dissertation moves along a traditional Noh three part macro-continuum, called Jo-Ha-Kyu, interpreted as enticement, crux and consolidation. Within these three parts, there are six further divisions. Part I consists of three sections: Section I, the introduction, sets the backdrop for the entire dissertation, that of Japan, and aims to draw the reader into its culturally unique and specific world. This section outlines the rationale for placing the ethnographer at the centre of the research, and presents Japan through the eyes of the writer. Section II outlines relevant Japanese cultural norms, mores and values, the English educational landscape of Japan and an overview of theatre in Japan and its possible influences on the Japanese university student today. Section III provides three literature reviews: second language acquisition, drama in education to process drama, and Content Language Integrated Learning. In Part 2, Sections IV and V respectively consist of the research methodology and the action research at the core of this dissertation. Section IV describes the case of Kwansei Gakuin University, then explains the design of the process drama curricula. Section V details the three-process drama projects based around the three social issues at the centre of this dissertation. There is also a description of an extra project that of the guest lecturer project. The ultimate goals of all four projects were to change motivation through English in a CLIL context, to develop linguistic spontaneity and to deepen emotional engagement with the themes. Part 3 serves to reflect upon the viability of using process drama in the Japanese university curriculum, and to critically self-reflect on the project as a whole.

Are they adicctied to college students social networks?

The development of the Internet and in particular of social networks has supposedly given a new view to the different aspects that surround human behavior. It includes those associated with addictions, but specifically the ones that have to do with technologies. Following a correlational descriptive design we present the results of a study, which involved university students from Social and Legal Sciences as participants, about their addiction to the Internet and in particular to social networks. The sample was conformed of 373 participants from the cities of Granada, Sevilla, Málaga, and Córdoba. To gather the data a questionnaire that was design by Young was translated to Spanish. The main research objective was to determine if university students could be considered social network addicts. The most prominent result was that the participants don’t consider themselves to be addicted to the Internet or to social networks; in particular women reflected a major distance from the social networks. It’s important to know that the results differ from those found in the literature review, which opens the question, are the participants in a phase of denial towards the addiction?

Museums and youth: between misunderstanding and disappointment. Youth perceptions and arguments about the cultural consumption of museums in Chile

Young people are less explored in museum audience research; this is a paradoxical situation when considering its strategic location in the cultural reproduction and if considering the high performing cultural consumption compared with other sectors. The phenomenon of museums consumption by young Chileans who are self recognized as public and non-public museums is explored from a qualitative approach. It was conducted with focus groups in the three largest cities in Chile (Santiago, Valparaíso and Concepción). They identify the museum as a cultural institution in full force. However, in questioning museums activity youth reveal the specificity of their cultural matrix. This is referred to a social temporality based on the fragment, the discourse of familiarity, proximity and instead of breaking and critical. They claim a museum aesthetic / historical experience based on pleasure and enjoyment. An overview is proposed to further clarify the youth cultural consumption to characterize more precisely the place of the museum in the set, to design more effective policies museums.
