Understanding PP placement in written Dutch : a corpus-based multifactorial investigation of the principal syntactic, semantic and discursive determinants

The present paper aims at refining current knowledge about the driving forces in Dutch constituent ordering of non-predicate prepositional phrases (PPs) as well as re-evaluating the common assumption in traditional Dutch reference grammars that the middle field position is the standard slot. Building on journalistic data in the Dutch Parallel Corpus, it is first shown that non-predicate PPs are significantly more often placed in postfield position (the structural position after the final verb cluster) than in middle field position (the position before the final verb cluster), which indicates that the postfield position rather than the middle field position should be considered the standard slot for PPs in written Dutch. Second, a binary logistic regression model was fitted with PP placement as a function of several syntactic, semantic and discursive predictor variables. This model is able to describe, explain and predict more than 80% of the variation in the data set, leading to a much better understanding of the mechanisms underlying PP placement in written journalistic Dutch. On the basis of our findings, we furthermore propose a refined and more fine-grained version of the theoretical framework in which PP placement in Dutch is traditionally described and understood

Asymmetric syntactic patterns in German-Dutch translation : a corpus-based study of the interaction between normalisation and shining through

The present study investigates how opposing translation universals (explanatory devices) as normalisation and shining through interact with each other. More particularly, we want to find out whether it is more likely to observe instantiations of shining through or (over-)normalisation in translations of contemporary literary fiction and whether the likelihood of these three explanatory devices varies according to translation direction. On the basis of a bidirectional comparable corpus of Dutch and German literary fictional texts (1975-2010), we investigated a case of syntactic variation that exists in both languages, viz. prepositional phrase (PP) placement. In both languages, a PP can be placed either in the middle field or in the postfield, but German presents a more outspoken preference for the middle field, thus making PP placement ideal for an investigation of the interaction between shining through and (over)normalisation. The results of the analyses show that (i) there is a strong form of shining through present in Dutch texts translated from German and (ii) a strong form of normalisation in German texts translated from Dutch. These results confirm Toury’s hypothesis that a less prestigious language such as Dutch is more tolerant towards higher frequencies of linguistic features which are typical of highly prestigious source languages as German than the other way around

Fast and robust bootstrap for multivariate inference: the R package FRB

We present the FRB package for R, which implements the fast and robust bootstrap. This method constitutes an alternative to ordinary bootstrap or asymptotic inference procedures when using robust estimators such as S-, MM- or GS-estimators. The package considers three multivariate settings: principal components analysis, Hotelling tests and multivariate regression. It provides both the robust point estimates and uncertainty measures based on the fast and robust bootstrap. In this paper we give some background on the method, discuss the implementation and provide various examples

Everyday walking with Parkinson's disease: understanding personal challenges and strategies

PURPOSE: This qualitative study was designed to explore the personal experience of everyday walking with Parkinson's disease (PD), the challenges and the strategies employed to compensate for difficulties, to help contextualise the scientific knowledge base. METHODS: Semi-structured interviews were undertaken with a sample of 20 people with idiopathic PD (12 male, 8 female; mean age 65 years (range 50 - 80); mean disease duration 10 years (range 2.5 - 26). Verbatim interview transcripts were analyzed thematically using NUD*IST N6 qualitative data analysis software. RESULTS: Walking was invariably performed as an integral part of a purposeful activity within a specific context, termed walking 'plus', with challenges encountered by people with PD in three main areas: Undertaking tasks; negotiating environments; and making transitions to walking. The two key strategies to compensate for difficulties experienced were monitoring through the use of concentration, and correcting through generating rhythm and size of steps. Carers supported monitoring and correcting. CONCLUSION: People with PD need to constantly assess and drive their walking performance. Attentional resources, which can themselves be compromised in PD, were used to accomplish what is normally a largely automatic activity. Personal accounts support scientific hypotheses. Rehabilitation interventions and measurements in PD need to reflect both the physical and psychosocial context of everyday walking

Mobile Networking

We point out the different performance problems that need to be addressed when considering mobility in IP networks. We also define the reference architecture and present a framework to classify the different solutions for mobility management in IP networks. The performance of the major candidate micro-mobility solutions is evaluated for both real-time (UDP) and data (TCP) traffic through simulation and by means of an analytical model. Using these models we compare the performance of different mobility management schemes for different data and real-time services and the network resources that are needed for it. We point out the problems of TCP in wireless environments and review some proposed enhancements to TCP that aim at improving TCP performance. We make a detailed study of how some of micro-mobility protocols namely Cellular IP, Hawaii and Hierarchical Mobile IP affect the behavior of TCP and their interaction with the MAC layer. We investigate the impact of handoffs on TCP by means of simulation traces that show the evolution of segments and acknowledgments during handoffs.Publicad

Does cueing training improve physical activity in patients with Parkinson's disease?

Patients with Parkinson’s disease (PD) are encouraged to stay active to maintain their mobility. Ambulatory activity monitoring (AM) provides an objective way to determine type and amount of gait-related daily activities. Objective To investigate the effects of a home cueing training program on functional walking activity in PD. Methods In a single-blind, randomized crossover trial, PD patients allocated to early intervention received cueing training for 3 weeks, whereas the late intervention group received training in the following 3 weeks. Training was applied at home, using a prototype cueing device. AM was applied at baseline, 3, 6, and 12 weeks in the patient’s home, to record body movements. Postures and motions were classified as percentage of total time spent on (a) static activity, further specified as % sitting and % standing, and (b) % dynamic activity, further specified as % walking, % walking periods exceeding 5 seconds (W>5s) and 10 seconds (W>10s). Random coefficient analysis was applied. Results A total of 153 patients participated in this trial. Significant improvements were found for dynamic activity ( = 4.46; P 5s ( = 2.63; P 10s ( = 2.90; P < .01). All intervention effects declined significantly at 6 weeks follow-up. Conclusion Cueing training in PD patients’ own home significantly improves the amount of walking as recorded by AM. Treatment effects reduced after the intervention period, pointing to the need for permanent cueing devices and follow-up cueing training
