The Research Space: using the career paths of scholars to predict the evolution of the research output of individuals, institutions, and nations

In recent years scholars have built maps of science by connecting the academic fields that cite each other, are cited together, or that cite a similar literature. But since scholars cannot always publish in the fields they cite, or that cite them, these science maps are only rough proxies for the potential of a scholar, organization, or country, to enter a new academic field. Here we use a large dataset of scholarly publications disambiguated at the individual level to create a map of science-or research space-where links connect pairs of fields based on the probability that an individual has published in both of them. We find that the research space is a significantly more accurate predictor of the fields that individuals and organizations will enter in the future than citation based science maps. At the country level, however, the research space and citations based science maps are equally accurate. These findings show that data on career trajectories-the set of fields that individuals have previously published in-provide more accurate predictors of future research output for more focalized units-such as individuals or organizations-than citation based science maps

Germany 2007: Undiminished High Construction Production and Increased Construction Prices

After the high growth of 2006, the first quarter of 2007 also shows undiminished high construction production. Evidence of this is provided by the number of hours worked, which see growth rates in double figures in all fields of civil and structural engineering; yet it is surprising that growth in industrial construction lagged somewhat. It remains to be seen to what extent the extremely strong increase in the performance of the construction industry reflects demand or simply consistently favourable weather conditions, for there was actually no real winter in the two quarters preceding and following the new year. Data on the finishing industry in the first quarter indicates a lower dynamics - the number of hours worked increased by almost 8%, compared with 24% in the construction industry. This means that the demand for construction work and services related to existing buildings, particularly in housing construction, is not continuing at the high level last achieved.Housing demand, Construction industry, Forecast 2007

Designing and Evaluating the Use of Smartphones to Facilitate Online Testing in Second-Language Teacher Education (SLTE): An Auto-Ethnographic Study

Abstract—This paper reports on an auto-ethnographic study of the use of smartphones to facilitate online testing in the context of second-language teacher education (SLTE). A total of 54 pre-service teachers participated in the study. Preliminary data were collected through observation and written reflection, and additional data were gathered from interviews and students’ web activity logs to enable triangulation. Thematic analysis was carried out on the qualitative data. The findings show that smartphones are a viable electronic tool to facilitate online testing in an SLTE context. More importantly, using Moodle as an online test platform meets both teachers’ and students’ needs with respect to aspects such as design, test structure and online testing activity. The study also highlights some benefits and challenges of employing sequential and multiple- attempt test modes and providing delayed feedback on online tests. The implications of these findings are discussed, with suggestions for further research in the field

Distributed-Pair Programming can work well and is not just Distributed Pair-Programming

Background: Distributed Pair Programming can be performed via screensharing or via a distributed IDE. The latter offers the freedom of concurrent editing (which may be helpful or damaging) and has even more awareness deficits than screen sharing. Objective: Characterize how competent distributed pair programmers may handle this additional freedom and these additional awareness deficits and characterize the impacts on the pair programming process. Method: A revelatory case study, based on direct observation of a single, highly competent distributed pair of industrial software developers during a 3-day collaboration. We use recordings of these sessions and conceptualize the phenomena seen. Results: 1. Skilled pairs may bridge the awareness deficits without visible obstruction of the overall process. 2. Skilled pairs may use the additional editing freedom in a useful limited fashion, resulting in potentially better fluency of the process than local pair programming. Conclusion: When applied skillfully in an appropriate context, distributed-pair programming can (not will!) work at least as well as local pair programming

Preliminary Numerical Study on Designing Navigation and Stability Control Systems for ITS AUV

In this paper, the numerical study of designing on navigation and stability control system for AUV is studied. The study started by initiating hydrostatic forces, added masses, lift force, drag forces and thrust forces. Determining the hydrodynamic force which is the basic need to know the numerical case study on designing on navigation and stability control system for AUV where Autonomous Underwater vehicles (AUV). AUV is capably underwater vehicle in moving automatically without direct control by humans according to the trajectory. The result of numerical study is properly to be the reference for the next developing for AUV

Preliminary Study on Magnetic Levitation Modeling Using PID Control

This paper proposes to understand about basic magnetic levitation model. Magnetic Levitation is repulsive or attractive force resulting gap from magnetic field. Characteristic of the magnetic levitation model is used permanent magnet and electromagnet with PID control to maintain wide gap between levitator and object levitation. Mass addition is used to analysis the model of the Maglev with PID control to maintain wide gap. Calculation result show that the maglev with PID control has sufficient levitation force in the maintain wide gap. Comparison between calculated and measured values can be done to build a another complex model magnetic levitation
