Inheritance and the Dynamics of Party Identification

Extensive research efforts notwithstanding, scholars continue to disagree on the nature and meaning of party identification. Traditionalists conceive of partisanship as a largely affective attachment to a political party that emerges in childhood through parental influences and tends to persist throughout life. The revisionist conception of partisanship is that of a running tally of party utilities that is updated based on current party performance. We attempt to reconcile both schools of thought in an individual difference perspective, showing that the party loyalties acquired through parental influences confirm better the traditional view, while the attachments of individuals who did not inherit their parents' party loyalties exhibit features more closely matching the revisionist predictions. The analysis is facilitated by uniquely suited longitudinal household data emanating from the German Socio-Economic Panel Study that allow to study party identifications of young adults and their parents on an annual basis from 1984 to 2007.The final publication is available at www.springerlink.com: http://dx.doi.org/10.1007/s11109-009-9084-

How to use the International Classification of Functioning, Disability and Health as a reference system for comparative evaluation and standardized reporting of rehabilitation interventions

Rehabilitation aims to optimize functioning of persons experiencing functioning limitations. As such the comparative evaluation of rehabilitation interventions relies on the analysis of the differences between the change in patient functioning after a specific rehabilitation intervention versus the change following another intervention. A robust health information reference system that can facilitate the comparative evaluation of changes in functioning in rehabilitation studies and the standardized reporting of rehabilitation interventions is the International Classification of Functioning, Disability and Health (ICF). The objective of this paper is to present recommendations that Cochrane Rehabilitation could adopt for using the ICF in rehabilitation studies by: 1) defining the functioning categories to be included in a rehabilitation study; 2) specifying selected functioning categories and selecting suitable data collection instruments; 3) examining aspects of functioning that have been documented in a study; 4) reporting functioning data collected with various data collection instruments; and 5) communicating results in an accessible, meaningful and easily understandable way. The authors provide examples of concrete studies that underscore these recommendations, whereby also em-phasizing the need for future research on the implementation of specific recommendations, e.g. in meta-analysis in systematic literature reviews. Furthermore, the paper outlines how the ICF can complement or be integrated in established Cochrane and rehabilitation research structures and methods, e.g. use of standard mean difference to compare cross-study data collected using different measures, in developing core outcome sets for rehabilitation, and the use of the PICO model. © 2019 EDIZIONI MINERVA MEDICA

Partisan choices in a direct-democratic campaign

Ever since Lazarsfeld and his colleagues' (1944) seminal study, it has become common wisdom that election campaigns, if anything, serve the activation of voters' fundamental predispositions. However, disagreement emerges on the role of partisan orientations. Although some authors consider them as fundamental predispositions, which are activated during the campaign and subsequently act as filters for incoming information, others argue that party attachments are simple running tallies of political assessments, which are constantly updated in response to campaign events, or decision shortcuts for voters innocent of substantial information. In this study, we scrutinize the role of partisan orientations in a direct-democratic campaign using data from a panel survey fielded during the run-up to the 2006 Swiss asylum law referendum. We find that, as voters accumulate knowledge in the course of the campaign, vote intentions dramatically converge on pre-campaign partisan orientations. Moreover, voters, whose earlier issue-specific and partisan orientations collide, tend to resolve their ambivalence in favour of their partisan leanings. These results corroborate the view of partisanship as a fundamental predispositio

International classification of functioning, disability and health core sets for children and youth with cerebral palsy: a consensus meeting

AIM: The objective of this article is to report on the Core Sets developed for children and youth aged 0 to 18 years, with cerebral palsy (CP) based on the pediatric International Classification of Functioning, Disability and Health (ICF) by the World Health Organization (WHO).METHOD: A formal decision-making and consensus process integrating evidence gathered from preparatory studies was followed. Preparatory studies included: a systematic literature review; an international expert survey; a qualitative study of children and youth with CP and their caregivers; and a clinical study. Relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. Twenty-six international experts chosen by WHO region with expertise in CP attended the consensus meeting.RESULTS: Overall, five ICF Core Sets were developed: a Comprehensive Core Set (135 ICF categories); a Common Brief (25 ICF categories); and three age-specific Core Sets: under 6 years (31 ICF categories), from 6 to &lt;14 years (35 ICF categories) and from 14 to 18 years (37 ICF categories).INTERPRETATION: These ICF Core Sets for children and youth with CP are the first ICF-based tools developed for this population. The ICF Core Sets for children and youth with CP can be applied in clinical practice, research, teaching and administration. The application of the ICF Core Sets to this population will standardize the functional assessments of CP worldwide.<br/

The conventional wisdom about tactical voting is wrong

Have you ever voted for another party because you felt that your party had no chance of winning the seat? If yes, then you might be among the 5 to 10 per cent of tactical voters. In this article, Michael Herrmann, Simon Munzert, and Peter Selb explain how, contrary to popular belief, the Liberal Democrats were the big winners of tactical voting in 1997 and 2001

TARGETED PRINCIPLE COMPONENT ANALYSIS: A NEW MOTION ARTIFACT CORRECTION APPROACH FOR NEAR-INFRARED SPECTROSCOPY

As near-infrared spectroscopy (NIRS) broadens its application area to different age and disease groups, motion artifacts in the NIRS signal due to subject movement is becoming an important challenge. Motion artifacts generally produce signal fluctuations that are larger than physiological NIRS signals, thus it is crucial to correct for them before obtaining an estimate of stimulus evoked hemodynamic responses. There are various methods for correction such as principle component analysis (PCA), wavelet-based filtering and spline interpolation. Here, we introduce a new approach to motion artifact correction, targeted principle component analysis (tPCA), which incorporates a PCA filter only on the segments of data identified as motion artifacts. It is expected that this will overcome the issues of filtering desired signals that plagues standard PCA filtering of entire data sets. We compared the new approach with the most effective motion artifact correction algorithms on a set of data acquired simultaneously with a collodion-fixed probe (low motion artifact content) and a standard Velcro probe (high motion artifact content). Our results show that tPCA gives statistically better results in recovering hemodynamic response function (HRF) as compared to wavelet-based filtering and spline interpolation for the Velcro probe. It results in a significant reduction in mean-squared error (MSE) and significant enhancement in Pearson’s correlation coefficient to the true HRF. The collodion-fixed fiber probe with no motion correction performed better than the Velcro probe corrected for motion artifacts in terms of MSE and Pearson’s correlation coefficient. Thus, if the experimental study permits, the use of a collodion-fixed fiber probe may be desirable. If the use of a collodion-fixed probe is not feasible, then we suggest the use of tPCA in the processing of motion artifact contaminated data

Is Seeing Believing? How Television Advertisements Influence Investment Decisions

Stock returns are influenced by many factors. Finance scholars have attempted to examine the potential causes of stock price changes by comparing the observed returns of stocks after an event with the predicted returns they should have experienced had the event not occurred. The current “Super Bowl-Stock Returns” studies tend to find conflicting results regarding whether the returns of Super Bowl advertisers’ stocks deviate from their predicted values during the trading days following the Super Bowl, as well as the direction in which these returns deviate and why they deviate. This study uses a more precise model for estimating predicted stock prices than those used in previous studies to find that the returns of Super Bowl advertisers\u27 stocks tend to not deviate from the predicted returns they would have experienced should the Super Bowl advertising not have happened. This study finds that the variance in abnormal returns is not correlated with measures of behavioral biases previously explored

Validating a new methodology for optical probe design and image registration in fNIRS studies

Functional near-infrared spectroscopy (fNIRS) is an imaging technique that relies on the principle of shining near-infrared light through tissue to detect changes in hemodynamic activation. An important methodological issue encountered is the creation of optimized probe geometry for fNIRS recordings. Here, across three experiments, we describe and validate a processing pipeline designed to create an optimized, yet scalable probe geometry based on selected regions of interest (ROIs) from the functional magnetic resonance imaging (fMRI) literature. In experiment 1, we created a probe geometry optimized to record changes in activation from target ROIs important for visual working memory. Positions of the sources and detectors of the probe geometry on an adult head were digitized using a motion sensor and projected onto a generic adult atlas and a segmented head obtained from the subject's MRI scan. In experiment 2, the same probe geometry was scaled down to fit a child's head and later digitized and projected onto the generic adult atlas and a segmented volume obtained from the child's MRI scan. Using visualization tools and by quantifying the amount of intersection between target ROIs and channels, we show that out of 21 ROIs, 17 and 19 ROIs intersected with fNIRS channels from the adult and child probe geometries, respectively. Further, both the adult atlas and adult subject-specific MRI approaches yielded similar results and can be used interchangeably. However, results suggest that segmented heads obtained from MRI scans be used for registering children's data. Finally, in experiment 3, we further validated our processing pipeline by creating a different probe geometry designed to record from target ROIs involved in language and motor processing

Functional tomography using a time-gated ICCD camera

We present a system for near infrared functional tomography based on a single pulsed source and a time-gated camera, for non-contact collection over a large area. The mean penetration depth of diffusely reflected photons is dependent on the arrival time of photons, but not on the source–detector distance. Thus, time-encoded data can be used to recover depth information while photon exiting point is exploited for lateral localization. This approach was tested against simulations, demonstrating both detection and localization capabilities. Preliminary measurements on inhomogeneous phantoms showed good detection sensibility, even for a low optical perturbation, and localization capabilities, yet with decreasing spatial resolution for increasing depths. Potential application of this method to in vivo functional studies on the brain is discussed
