Strategien zur webbasierten Multilingualen Fragebeantwortung

Zusammenfassung  Wir stellen eine Reihe von innovativen Methoden zur webbasierten multilingualen Fragebeantwortung in offenen Dom?nen vor. Insbesondere werden neuartige Strategien zur Bestimmung optimaler Antwortkontexte und zur Extraktion von exakten Antworten auf Basis von sprachunabh?ngigen, datengetriebenen maschinellen Lernverfahren beschrieben. Es werden zwei alternative Methoden für die crosslinguale Frageanalyse skizziert mit deren Hilfe für eine Anfrage in einer natürlichen Sprache Antworten in Dokumenten einer anderen natürlichen Sprache bestimmt werden k?nnen. Alle Methoden sind detailliert evaluiert und weisen eine vielversprechende Performanz auf. CR subject classification  I.2.6 ; I.2.7 ; J.1 ; K.3.2 ; D.3.3 ; D.2.2     

Auswertung von elektromyographischen Signalen zur Steuerung von Exoskeletten

Zusammenfassung  Diese Arbeit stellt ein Modell und ein System zur Steuerung von Exoskeletten mit Hilfe von elektrischen Signalen vor, die an den Muskeln des Benutzers gemessen werden. Anhand dieser Signale wird der eigene Drehmomentbeitrag des Benutzer zur gewünschten Bewegung abgesch?tzt, und ein einstellbarer Faktor bestimmt das vom Exoskelett hinzugefügte Drehmoment in Bezug auf den Beitrag des Benutzers. Die Signale werden durch ein komplexes biomechanisches Modell ausgewertet. CR subject classification  J.3 ; J.7 ; I.6.5     

Setting by numbers: datafication processes and ability grouping in an English secondary school

ABSTRACT

With the rise of accountability policies since the early nineties, the daily operation of English schools has profoundly changed. Through the in-depth analysis of ability grouping practices in one English secondary school, this paper aims to explore how the accountability shift and datafication impacted the practice of student grouping and students’ experience of education. The paper documents how an English secondary school which had fully endorsed the comprehensive ideal gradually shifted from mixed ability teaching to a rigid system of hierarchically arranged attainment-based grouping structure over a period of decades, and explores the pedagogical dilemmas that data-driven governance generates. The paper concludes that the school’s data-driven practice creates an environment of competition and an experience of incessant insecurities for the students which unsettlingly echo the culture of the late neoliberal labour market.     

Paradigm development and leadership style of university department chairpersons

This article develops and tests the argument that leadership behavior in organizations can best be understood within a contingency technology-environment model. The major premise of this model is that one of the most influential intervening factors between organizational performance and leadership behavior is either the technology that the organization utilizes or the environment with which the organization interacts. Building upon this premise and the work of Kuhn (1970), four hypotheses are tested concerning the relationship between the effectiveness of natural science and social science departments in American universities using factor analysis. The data supports the conclusion that differential leadership styles are predictable in different scientific fields.     

Teaching science skills and knowledge to students with developmental disabilities: A systematic review

A comprehensive review of the literature was conducted to identify current practice on teaching science to students with intellectual disability (ID) and/or Autism Spectrum Disorder (ASD) in relation to two review questions—students' science outcomes and students' and teachers' experiences of the interventions. Six databases related to education, psychology, and science were systematically searched. A detailed protocol can be viewed on PROSPERO (registration number: CRD42017057323). Thirty studies were identified that reported on science interventions and 20 on student/teacher experiences of the interventions. The majority of the studies targeted science vocabulary and concepts. Other targets included inquiry skills and comprehension skills. The majority of the interventions used components of systematic instruction (n = 23). Five studies focused on self-directed learning and two on comprehension-based instruction. Students and teachers reported positive experiences of the interventions. The findings suggest that components of systematic instruction in particular might be effective in teaching science content to students with ID and/or ASD. Further research is needed to explore the effectiveness of identified interventions on teaching more complex science skills and with students with severe disabilities. Some limitations related to the search strategy are highlighted.     

Field dependence/independence cognitive style and problem posing: an investigation with sixth grade students

Field dependence/independence cognitive style was found to relate to general academic achievement and specific areas of mathematics; in the majority of studies, field-independent students were found to be superior to field-dependent students. The present study investigated the relationship between field dependence/independence cognitive style and problem-posing ability among sixth grade students. The 94 students’ sample was clustered into three groups, according to the cognitive-style field dependence/independence (field dependents, field mixed and field independents). The results suggest that field-independent participants outperformed field-mixed and field-dependent ones in both problem-posing ability and the complexity of the problems posed. It was also found that the content of the task influenced the differences between the three groups of students as regards the ability in problem posing and the complexity of the problems posed; while in the first (informal context), second and fourth task differences were found between the groups, in the third task (formal context), no differences were evident. The results are interpreted in consideration to the relevant literature findings. Some educational implications are discussed and directions for future research are drawn.     

On Masters and Apprentices in Physical Education

This paper discusses the impact of the mentoring role of faculty on fostering a quality educational experience for graduate students. Although potentially significant graduate students naturally gravitate to work with significant faculty, it is the mentoring role of the advisor that allows the student's potential to be realized. Clues to the impact of this mentoring role are gleaned from Zuckerman's (1977) analysis of American Nobel Prize laureates. To promote a quality advisor–student relationship, departments need to look beyond the student and considerations of the norms and regulations of entrance and ongoing program criteria. One necessary and very significant precursor will be the presence of quality faculty.     

The effect of gender,deceit orientation and communicator style on macro‐assessments of honesty

Recently, deception research has focused primarily on micro‐analytic methods of lie detection (e.g., eye contact duration, response latency, vocal errors). This study adopted a macro‐assessment approach, where deception detection is based on global evaluations of communication, specifically honesty evaluation based on communicator style. 385 subjects viewed four different videotape segments of individuals participating in a simulated job interview. Two of the individuals were truthful throughout the interview, and two fabricated false information on some questions. Subjects were asked to evaluate or assess the honesty level of these individuals, as well as assess a number of communicator style dimensions. Multiple regression analyses revealed that honesty assessments can be predicted from communication style characterized by high friendliness, attentiveness, and preciseness, and low animated and dramatic styles. Some differences were observed for communicator style predictions of honesty based on liars/truthers, subject gender, target gender, and deceit‐orientation differences. Implications for future research are noted.     

FACULTY ATTITUDES TOWARD INSTITUTIONAL COMPETITIVE STRATEGIES IN U.S. RESEARCH UNIVERSITIES

The present study aims at assessing faculty attitudes toward institutional competitive strategies in U.S. research universities and at exploring some of the correlates of these attitudes.

A stratified random sample of 40 U.S. research university departments, 10 each in physics, sociology, electrical engineering, and education was surveyed by means of a questionnaire.

The major findings of this study suggest that faculty members at research universities express non‐receptive attitudes toward university generic strategies, although, more productive,more satisfied and more committed faculty members are relatively more receptive toward university strategies than less productive, less satisfied and less committed faculty members.

The meaning and the implications of these findings are discussed.
