The present study focuses on the Benthic Macroinvertebrate Fauna of natural running waters and semi-natural stagnant waters of Himalayan region and Lowlands in the Ganges River Basin. Habitat quality assessment using three different biotic scores was applied for 32 sampling sites of running waters and 26 sampling sites of stagnant waters. Benthic Macroinvertebrates were used as bio-indicators. Calculation of water quality was done based on a recently established five-class system, to describe the degree of organic pollution. Sampling localities are covering all longitudinal biocoenotic zones and lateral zones to include the traditionally well defined types of running and stagnant waters of altitudinal range from 54- to 2480 m asl. The impact of natural organic load was studied to describe the variation of Ecological quality classes within different eco-regions. Ecological quality was defined as a result of the water quality class together with the eco-morphology status of the water body. Class I (Excellent) is present only in spring-near headwaters of forested areas or in running waters coming from higher elevations between 490 to 2500 m asl. Class II (Good) and III (Moderate) is the normal reference condition for lowlands and the Gangetic plains. Wetlands, oxbow-lakes and "old" ponds have usually class II or III, independent from the grade of forests due to natural organic load accumulated during monsoon flood. Water quality undergoes seasonal changes from III (moderate) in pre-monsoon to II (good) during and after monsoon. The highest diversity with >30-42 identified taxa per sampling site (Class I) was found in the Rhithron zone of densely forested parts of Nepal, followed with >20-30 identified taxa by the Metapotamon zone (Class II, III) of large rivers in the Gangetic Plains of India. In stagnant water bodies the maximum diversity reaches >30-76 identified taxa (Class II, III) in Nepal and Maharashtra between 197-1170 m asl, whereas the floodplain wetland diversity reaches only 27 taxa (Class III). The proposed use of selected Insect-groups as bio-indicators for Lowlands and Middle Mountains includes colored illustrated catalogue of Dragonflies (Odonata), Bugs (Heteroptera), and Cockroaches (Blattodea). 12 families with 31 taxa of Odonata Nymphs, 14 families with 27 taxa of Heteroptera Nymphs and Adults, one family with two taxa of Blattodea Nymphs and Adults are described and figured with identification characters and ecological habitat observations. This will be the first key based on material mainly from Nepal and India for the Ganges River Basin.
Historically – if one can say that given the infancy of the field – environmental plastic debris has been the baby of marine research. Driven by the rediscovery of long forgotten, 1970s studies on the occurrence of small plastic fragments (today termed microplastics) in the oceans, oceanographers and marine biologists resurrected the topic in the early 2000s. Since then, the field has rapidly expanded and established that plastics are ubiquitous in the marine system, from the Arctic to Antarctic and from the surface to the deep sea. ...
The research reported in this thesis examines two main questions: firstly, which dictionary type, bilingual or monolingual, is most effective for intermediate learners of German for reading comprehension, and secondly, which features make monolingual dictionary definitions effective for these learners. These questions divide the thesis into two parts. The first part compares the effectiveness of the bilingual versus the monolingual dictionary, and the second part compares two different monolingual definition styles.
The research was originally motivated by the observation that Hong Kong Chinese intermediate learners of German prefer to use a German-English bilingual dictionary. Since the translations are presented in the learners' second language, the effectiveness of this bilingual dictionary is doubtful. On the other hand, the learners are reluctant to use the monolingual dictionary, recommended to them by their language teachers. Three investigations were conducted in order to gain more detailed knowledge about the learners' dictionary preference, and the effectiveness of the two dictionary types. The learners' dictionary preference was investigated by means of a survey of ninety-eight foreign language students. The effectiveness of the bilingual and monolingual dictionary for reading comprehension and incidental vocabulary learning was first measured experimentally. The think-aloud method was then used in order to discover factors which determine the effectiveness of the two dictionary types.
The results of the experiment revealed that the German-English bilingual dictionary was not significantly more effective for the learners than the monolingual dictionary. The only monolingual dictionary available for German at that time, however, is linguistically too difficult for this proficiency level. Because of these findings, the research turned to monolingual dictionary definitions with the aim of identifying features that make them accessible to intermediate learners. Based on findings from the first think-aloud study, and principles promoted as user-friendly in the lexicographic literature, new definitions were developed for the target words in the research. These new definitions were compared with those in the existing dictionary. A second think-aloud study was conducted in order to generate hypotheses about individual definition features. These hypotheses were then tested in the second experiment, which was conducted with eighty-six learners of German in Shanghai.
The investigations reveal several features that determine the effectiveness of monolingual definitions for intermediate learners. The findings have theoretical and pedagogical implications. In the theoretical field, some lexicographic principles were recommended that are, unlike previous principles, based on empirical insights into user needs. In the pedagogical field, the research findings provide an empirical basis for the evaluation and recommendation of suitable dictionaries to intermediate learners.
A model of dictionary effectiveness is proposed. This model could help to assess the effectiveness of different information categories in dictionaries for different proficiency levels and different activity contexts. It could also provide lexicographic principles for the design of dictionaries. This research contributes one component to the proposed model: criteria for the effectiveness of definition features for intermediate learners in the activity context of reading.
Be it in the case of opening a website, sending an email, or high-frequency trading, bits and bytes of information have to cross numerous nodes at which micro-decisions are made. These decisions concern the most efficient path through the network, the processing speed, or the priority of incoming data packets.
Despite their multifaceted nature, micro-decisions are a dimension of control and surveillance in the twenty-first century that has received little critical attention. They represent the smallest unit and the technical precondition of a contemporary network politics – and of our potential opposition to it. The current debates regarding net neutrality and Edward Snowden’s revelation of NSA surveillance are only the tip of the iceberg. What is at stake is nothing less than the future of the Internet as we know it.
European Music Portfolio (EMP) – Maths: 'Sounding ways into mathematics' : teacher’s handbook
(2016)
Music and mathematics share an odd character: many people believe that they are not good at one or the other (or both). However, ‘I cannot sing’ or ‘I never understood mathematics’ will probably not keep them from having successful careers, and nor will it change the opinions others have about them.
The project ‘European Music Portfolio – Sounding Ways into Mathematics’ (EMP-Maths) aims towards a different understanding with regards to this character. Everyone can sing and make music, and everyone can do mathematics. Both topics are integral parts of our life and society. What needs to be improved is our ability to give students opportunities to like them.
This teacher’s handbook presents activities with different mathematical and musical content in order to offer teachers resources, ideas and examples. These activities are designed to be expandable, adaptable to different contexts, and adjustable to the needs of each teacher and their students. Furthermore, these activities are not just planned to be carried out individually; a teaching unit could be used to make sense of them, or they could even be developed in connection with each other.
Apart from this teacher’s handbook, the project provides a continuing professional development (CPD) course, a webpage (http://maths.emportfolio.eu) from which all materials can be downloaded, and an online collaboration platform. A general overview of related literature and research is available in separate documents. Additional teacher booklets provide related materials and a brief overview of the theoretical background, and are the basis for the CPD courses. The project ‘Sounding Ways into Mathematics’ is related to the EMP-Languages project ‘A Creative Way into Languages’ (http://emportfolio.eu/emp/).

This thesis investigates how students with Cantonese (L1) and English (L2) backgrounds acquire German as a third language (L3), with a focus on the acquisition of the Vorfeld (fronting) constructions of German. In L3 studies, the roles played by mother tongue, L2 and developmental grammar may be distinguished. Previous L3 studies have suggested that the role of L2 seems to be prominent in L3 strategy building, including interlanguage transfer from L2 to L3. Pursuing a cognitive approach, we argue that incremental production and language processing strategies are significant factors in accounting for third language acquisition and production.
A total of 45 university students of German completed a questionnaire and submitted copies of their compositions, followed by picture elicitation tasks. Three typical fronting types were found to be common amongst the learners:
1. Für mich, jede Familie hat eigene Situation und Probleme.
2. Obwohl gibt es viele Probleme mit alten Leuten zusammen lebt, finde ich gut dafür.
3. Jetzt die meisterns haben schon nach Hong Kong zurückgekommen.
Type 1 is argued to reflect indirect transfer of native language function-form characteristics. Type two is argued to be an intralingual error in which the learners have overgeneralized the verb second (V2) rule, without acquiring the correct function of the Vorfeld construction. The third type shows that apart from the influence of English in adverb fronting constructions, adverbs of stance or perspective adverbs like ‘jetzt’ semantically do not form part of the proposition and they are therefore treated as “extra-sentential” constituents which do not affect the basic V2 construction.
The findings suggest that learners may have primarily acquired the topic function of German fronting, while failing to fully acquire the focus function. For the focus function, learners seem to prefer alternative constructions such as existential sentences using ‘es gibt’. Both of these findings implicate L1 Chinese influence.
As an overall perspective on the incipient field of third language acquisition research I propose a holistic and coherent view which encompasses syntax, semantics and pragmatics at all levels of language development. By probing an independent paradigm of L3 studies, we aim to contribute to a new dynamic research space as well to ongoing debates in the SLA field by attributing greater autonomy and consciousness to the learner, even on the level of grammatical interaction.
I would like to start off my cultural-historical intervention with a trouvaille from the 'Denktagebuch', a sort of intellectual notebook, of Hannah Arendt, the famous German-Jewish philosopher (1906–1975). Arendt's publications include a most profound book on the 'Human Condition' (1958, in German 'Vita activa', 1960) in which she develops the idea of 'acting / Handlung' as the crucial realm of intersubjectivity and humanity. This realm is based in the space between human beings, a literal 'inter-est' of togetherness. It is only in this space, only in the relationship to others, that the full sense of the Self, including the involuntary expressions of the person, manifests itself. It is the same realm in which the moral, social and political life is created. In the notebook of the 44-year-old Arendt one comes across the following entry: "In nichts offenbart sich die eigentümliche Vieldeutigkeit der Sprache [...] deutlicher als in der Metapher. So habe ich zum Beispiel ein Leben lang die Metapher 'es öffnet sich mir das Herz' benutzt, ohne je die dazu gehörende physische Sensation erfahren zu haben. Erst seit ich die physische Sensation kenne, weiss ich, wie oft ich gelogen habe [...]. Wie aber hätte ich je die Wahrheit der physischen Sensation erfahren, wenn die Sprache mit ihrer Metapher mir nicht bereits eine Ahnung von der Bedeutsamkeit des Vorgangs gegeben hätte?" (Notebook II, 22 December 1950, Arendt 2002, 46) The entry discusses the mutual transferral between mind and body by reflecting the role of language as a mediator for minding the body and the embodiment of the mind. Since the phrase of the 'open heart' belongs to a register of long-established metaphors, these reflections concern the comprehension of body-metaphors and their role for a 'shared meaningful space of experiences' (Gallese 2009a, 527), i.e. language as transmitter of experiences and memory in cultural history.
