Retracted Article: Clinical effectiveness of continuous passive motion (CPM) following femoroacetabular impingement surgery in adolescents
Authors: Hosalkar Harish , Bomar James D. 
Published: June 2012

Purpose This study hypothesizes that the use of continuous passive motion (CPM) following open femoroacetabular impingement (FAI) surgery in the adolescent population improves clinical outcomes in terms of the modified Harris hip score (mHHS). Methods Twenty-nine symptomatic adolescent FAI patients were postoperatively divided into one of three groups; no CPM, two days of inpatient CPM, and two weeks of CPM. mHHS was used preoperatively and postoperatively at six weeks, three months, six months, and nine months in all cases. Kruskal–Wallis (KW) analysis was performed to determine statistical differences in mHHS. mHHS was then re-evaluated using the Mann–Whitney test. Results There were no statistically significant differences in hip scores between the three groups preoperatively ( p = 0.158). There were statistically significant differences ( p < 0.001) in mHHS between the three groups at all postoperative time periods. The group that received two weeks of CPM had the best outcome scores. Conclusion The results of this study suggest that postoperative CPM use following open hip preservation surgery for symptomatic FAI in adolescents improves clinical outcomes. These benefits seem to be related to the duration of CPM. Level of evidence Retrospective comparative study, Level III. Patients treated one way compared with patients treated another way at the same institution.

ObjectiveTo determine the proportion of persons with poststroke shoulder pain 4 months after onset of the stroke in whom long‐lasting shoulder pain develops and to assess the extent to which age, side of paresis at stroke onset, pain frequency and pain intensity, passive shoulder range of motion, resistance to passive movements, motor function, and subluxation at 4 months after stroke predict shoulder pain 1 year later.DesignA prospective study.SettingA university hospital outpatient clinical setting.ParticipantsFifty‐eight men and women with their first‐ever stroke (mean age, 71 years) and affected sensory‐motor function in the upper extremity at stroke onset who all reported shoulder pain in the affected side 4 months after onset of the stroke.MethodsAt 4 and 16 months after having a stroke, the participants rated their self‐perceived shoulder pain (frequency and intensity). Passive range of shoulder abduction and external rotation, resistance to passive movements in the elbow, and motor function in the shoulder were assessed by a physical therapist.Main Outcome MeasurementsA question about pain frequency (constant, often, or occasional), the Visual Analogue Scale for Pain for self‐perceived shoulder pain intensity, a goniometer for range of motion, the Modified Ashworth Scale for resistance to passive movements, and the Motor Assessment Scale for motor function.ResultsOf the 58 participants who had shoulder pain 4 months after having a stroke, 42 (72%) still had pain at 16 months. The logistic regression indicated an association between shoulder pain at 16 months and left‐sided hemiparesis at stroke onset (P = .01; odds ratio [OR] 10.47; 95% confidence interval [CI] 1.92‐57.05), pain frequency (P = .02; OR 6.85; 95% CI 1.46‐32.14), decreased passive abduction at 4 months (P = .05; OR 4.46; 95% CI 0.99‐20.10), and age (P = .07; OR 1.05; 95% CI 1.0‐1.12).ConclusionsA high proportion of persons with shoulder pain 4 months after having a stroke are at risk of having persistent shoulder pain 1 year later. Left‐sided hemiparesis, pain reported frequently, and decreased passive shoulder range of abduction at 4 months are predictors of long‐lasting poststroke shoulder pain and require increased attention in the rehabilitation setting.
Water colliding with oil
Authors: Quéré David 
Published: June 2012

AbstractThe collision of two liquid drops is both an applied question (in rain formation or combustion, for example) and a beautiful basic situation, where impact involves liquid phases, making this problem worth studying in its own right. In a stimulating paper, Planchette, Lorenceau & Brenn (J. Fluid Mech., this issue, vol. 702, 2012, pp. 5–25) consider collisions between oil and water, which often lead to water drops protected by a shell of oil. By looking at the deformations during impact, they characterize the dynamical conditions leading to single encapsulation, and derive a criterion for avoiding fragmentation.
Geochemistry, petrogenesis and tectonic implications of granitic plutons at the Liziyuan orogenic goldfield in the Western Qinling Orogen, central China

Published: June 2012

AbstractThe Liziyuan goldfield is located along the northern margin of the western part of the Qinling Orogen (WQO). The goldfield consists of five gold-only deposits hosted by metavolcanic rocks, and one polymetallic (Au–Ag–Pb) deposit hosted by the Tianzishan Monzogranite. As the Liziyuan goldfield appears to be spatially and temporally related to the Jiancaowan Porphyry, the study of the deposit provides a crucial insight into the relationship between tectonic-magmatic events and gold metallogenesis in the WQO. In this paper, we present whole-rock major and trace element geochemistry, andin situzircon U–Pb and Lu–Hf isotopic data from the Tianzishan Monzogranite and Jiancaowan Porphyry. The two granitic plutons are enriched in LILEs and LREEs, depleted in HFSEs and have zirconεHf(t) values between −14.1 and −5.1 for the Tianzishan Monzogranite and between −21.0 and −8.4 for the Jiancaowan Porphyry. These characteristics indicate that the granites are derived from the crust. The Tianzishan Monzogranite has LA-ICP-MS zircon U–Pb ages of 256.1 ± 3.7 to 260.0 ± 2.1 Ma, which suggests that it was emplaced in the WQO during the convergence of the North and South (Yangtze) China cratons in the early stage of the Qinling Orogeny. In contrast, the porphyry has a LA-ICP-MS zircon U–Pb age of 229.2 ± 1.2 Ma, which is younger than the peak collision age, but corresponds to the widespread Late Triassic post-collisional granitic plutons in the WQO. The Tianzishan Monzogranite has somewhat higher Sr contents (196–631 ppm), lower Y (2.23–19.6 ppm) and Yb (0.20–2.01 ppm) contents, and a positive Eu/Eu* averaging 1.15. These characteristics suggest the pluton was derived from partial melting of the thickened crust. In contrast, the relatively higher MgO content (0.85–2.08 wt%) and Mg no. (43.4–58.2) of the Jiancaowan Porphyry indicates that insignificant amounts of subcontinental lithospheric mantle-derived mafic melts were involved in the generation of the magma. The Liziyuan goldfield is hosted by faults in greenschist-facies metamorphic rocks. Fluid inclusion studies suggest that gold was precipitated from CO2-rich, low-salinity and medium temperature fluids. This feature is consistent with the other orogenic gold deposits throughout the world. The field relationships and zircon U–Pb ages of the two granitic plutons suggest that gold mineralization is coeval with or slightly younger than the emplacement of the Jiancaowan Porphyry. Therefore, both the porphyry and deposit formed during the post-collisional stage of the Qinling Orogen.
There's No Place Like Home: The Right to Live in the Community for People with Disabilities, Under International Law and the Domestic Laws of the United States and Israel
Authors: Kanter Arlene S 
Published: June 2012

This article explores the developing ‘right to live in the community’ for people with disabilities under international law and the domestic laws of two countries: the United States and Israel. In 2006, the United Nations adopted the Convention on the Rights of People with Disabilities (CRPD). This Convention embraces a human rights approach to disability, based on the principles of equality, dignity, freedom and inclusion. Based on these principles, Article 19 of the CRPD includes a specific right of all people with disabilities ‘to live in the community, with choices equal to others’. The author argues that the mandate of community living in Article 19 supports an explicit legal right of all people with disabilities not only to live in the community, but to choose where to live and with whom, and with supports, as needed. This new international legal right to live in one's home in the community also advances the goals and principles of the domestic laws of the US and Israel.In the US, the Americans with Disabilities Act (ADA) protects the right of people with disabilities to receive services in ‘the most integrated’ setting. Relying on this ‘integration mandate’, the US Supreme Court, in 1999, upheld a limited right of people with disabilities to live in the community inOlmstead v LC and EW. In Israel, the Parliament (Knesset) enacted a law similar to the ADA in 1998. This law, the Equal Rights of Persons with Disabilities Law (‘Equal Rights Law’) includes a general right of people with disabilities to equality and non-discrimination. Although the current version of the Equal Rights Law does not include a specific article on the right to live in the community, the basis for such a right may be found in other articles of the law as well as other Israeli laws. In addition, in the recent case ofLior Levy et al., the Israeli High Court of Justice was asked to consider the right to live in the community under Israeli law. While the Court in this case recognised a limited right to live in the community, it failed to invalidate as discriminatory the Israeli government's policy of placing people with disabilities in large institution-like hostels rather than in homes in the community. The author concludes the article with a discussion of the scope and meaning of community living and the extent to which institutions, as well as community housing that functions just like institutions, should be prohibited under the CRPD as well as under US and Israeli law.
Separate and Different: Single-Sex Education and the Quest for Equality
Authors: Hostovsky Brandes Tamar 
Published: June 2012

This article examines the separation of boys and girls in religious schools in Israel and the current Israeli policy that aims to balance the right of equality with the right of denominational education in state-funded, religious schools. It draws on the legacy of the case ofUnited States v Virginiaand the subsequent regulations published by the United States Department of Education in 2006 in order to determine when single-sex education may be compatible with equality. It then examines both the relevance and the application of the criteria developed in the United States to religious schools in Israel.The article reviews and examines the two main justifications for single-sex education: cultural/religious and feminist. The right to establish single-sex educational institutions is perceived to be part of a minority group's right to culture. In conservative cultures, separation between men and women is often justified as a means of preserving modesty and as a necessity in order to educate and train men and women towards their respective social roles. More often than not, their justifications are incompatible with liberal notions of gender equality and dignity.Separation of men and women in the area of education is often also justified, however, from a feminist standpoint, which is rooted in pedagogical theories. Proponents of single-sex education argue that women-only educational institutions circumvent the inherent bias against women prevalent in coeducational schools, relying on research that indicates that girls perform better in girl-only schools, and attributing this both to the method of study and the educational environment of girl-only schools. They argue that, while separation in other areas of life may be humiliating, in education it has the potential of being empowering.The goal of this article is to examine how the two types of justification come into play in single-sex religious education in Israel. The article claims that where separation between boys and girls is justified by cultural and religious arguments, it must withstand the tests developed in the case law for the legality of practices that are incompatible with equality. It also argues that even where separation is permissible, the manner in which it is carried out should be regulated and supervised to ensure the minimum violation of equality.
Managing Cultural Heritage in China: A View from the Outside
Authors: Zan Luca , Bonini Baraldi Sara 
Published: June 2012

AbstractThis article investigates change processes regarding the managerial aspects of organizing cultural heritage activities in China. The focus is not on the historical and artistic meanings of archaeological discoveries in themselves; nor on the technical, scientific and methodological repercussions of conservation and restoration; nor on the evolution of museology per se. Rather, the core of the analysis is on new managerial problems along the “archaeological chain” (archaeological discoveries, restoration, museum definition and public access to cultural heritage) posed by new professional discourse and the overall evolution of the economic and political context. The article is based on field research carried out in Luoyang, Henan province. The micro view adopted (managing practices more than policies), and the unusual access to data (including financial figures on individual entities) represent a unique opportunity for a sort of “journey” inside the Chinese public sector.
Restoring Chaos to History: Sino-Soviet-American Relations, 1969
Authors: Lüthi Lorenz M. 
Published: June 2012

AbstractSino-Soviet-American relations during 1969 followed a chaotic course. Scholars have asserted in the past that the Sino-Soviet border conflict in March led to Sino-American rapprochement in December. However, evidence from China, the former socialist world and the United States undermines the interpretation of a purposeful and planned policy of any of the three actors to the others. None had a formulated policy or strategy in place. China lacked the governmental ability to chart a clear course, the United States underwent a presidential transition, and neither it nor the Soviet Union had meaningful diplomatic relations with the People's Republic. In this context, the border clashes, intended by China to reassert territorial claims on a small island, led to a complex web of actions and interactions between the three countries that was based on mutual misunderstanding, lack of communication, exaggerated threat perceptions and improvised decision making. Thus the outcome at the end of the year, the start of a friendly relationship between Beijing and Washington, was by no means the result of well-formulated and implemented policies.
The Impacts of Language Background and Language-Related Disorders in Auditory Processing Assessment
Authors: Loo Jenny Hooi Yin , Bamiou Doris-Eva , Rosen Stuart 
Published: June 2012

PurposeTo examine the impact of language background and language-related disorders (LRDs—dyslexia and/or language impairment) on performance in English speech and nonspeech tests of auditory processing (AP) commonly used in the clinic.MethodA clinical database concerning 133 multilingual children (mostly with English as an additional language) and 71 monolingual children (7- to 12-year-old native English speakers) with listening concerns was analyzed retrospectively.ResultsLanguage background had no significant effect on the 3 nonspeech AP tests, but the multilingual group performed worse in most of the speech tests. Children with LRDs generally performed more poorly than those without, except for the masking level difference.ConclusionsAlthough language background affects performance in AP tasks that use speech, the effect of LRDs appears to be more wide-ranging insofar as the majority of the AP tests—speech and nonspeech—were significantly affected by their presence. The effects of language background are probably mediated directly through the effects of language expertise, whereas those associated with LRDs appear to arise from associated deficits in memory and attention. The vast majority of so-called AP tests tap abilities far beyond those typically thought of as specifically auditory; thus, they are poor measures of an AP disorder.
Past Tense Production by English Second Language Learners With and Without Language Impairment
Authors: Blom Elma , Paradis Johanne 
Published: June 2012

Purpose
This study investigated whether past tense use could differentiate children with language impairment (LI) from their typically developing (TD) peers when English is children’s second language (L2) and whether L2 children’s past tense profiles followed the predictions of Bybee’s (2007) usage-based network model.

Method
A group of L2 children with LI (L2-LI) and a matched group of L2-TD peers were administered the past tense probe from the Test of Early Grammatical Impairment (Rice & Wexler, 2001) and the Peabody Picture Vocabulary Test (Dunn & Dunn, 1997). A representative input corpus provided distributional information for each verb used. Background information was obtained via parent questionnaire.

Results

The L2-LI group used fewer tense-marked verbs than did the L2-TD group. In both groups, vocabulary size and word frequency predicted accuracy with regular and irregular verbs. Children omitted regular past tense marking most often after alveolar stops, dropping the allomorph /
i
d/; L2-TD children omitted /t/ more often than /d/. Finally, first language typology predicted past tense accuracy.

Conclusions
Past tense use could potentially differentiate between English L2 children with and without LI. The impact of vocabulary, frequency, and phonological factors supported the network model and indicated profile differences between L2-LI and L2-TD children.
The Effects of Short-Term Computerized Speech-in-Noise Training on Postlingually Deafened Adult Cochlear Implant Recipients
Authors: Ingvalson Erin M. , Lee Brienne , Fiebig Pamela , Wong Patrick C. M. 
Published: June 2012

Purpose
To determine if short-term computerized speech-in-noise training can produce significant improvements in speech-in-noise perception by cochlear implant (CI) recipients on standardized audiologic testing measures.

Method
Five adult postlingually deafened CI recipients participated in 4 speech-in-noise training sessions using the Seeing and Hearing Speech program (Sensimetrics; Malden, MA). Each participant completed lessons concentrating on consonant and vowel recognition at word, phrase, and sentence levels. Speech-in-noise abilities were assessed using the QuickSIN (Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004) and the Hearing in Noise Test (HINT (Nilsson, Soli & Sullivan, 1994)).

Results
All listeners significantly improved key word identification on the HINT after training, albeit only at the most favorable signal-to-noise ratio (SNR). Listeners also showed a significant reduction in the degree of SNR loss on the QuickSIN after training.

Conclusion
Short-term speech-in-noise training may improve speech-in-noise perception in postlingually deafened adult CI recipients.
Maxillary Arch Dimensions and Spectral Characteristics of Children With Cleft Lip and Palate Who Produce Middorsum Palatal Stops
Authors: Zajac David J. , Cevidanes Lucia , Shah Sonam , Haley Katarina L. 
Published: June 2012

Purpose
The purpose of this study was twofold: (a) to determine maxillary arch dimensions of children with repaired cleft lip and palate (CLP) who produced middorsum palatal stops and (b) to describe some spectral characteristics of middorsum palatal stops.

Method

Maxillary arch width, length, and height dimensions and first spectral moments of /t/-/k/ contrast words were determined for three groups of children ages 7–11 years: (a) with CLP who were clinically judged to produce middorsum palatal stops (
n
= 5), (b) with CLP but without middorsum palatal stops (
n
= 6), and (c) typically developing controls (
n
= 8). Validity of clinical judgments of middorsum palatal stops was assessed by adult listeners via forced-choice identification of /t/-/k/ contrast words.

Results

Listeners confirmed production of middorsum palatal stops for 4 of 5 children with CLP. These children had (a) the narrowest anterior maxillary arch width relative to posterior arch width (
p
= .011) and (b) the lowest first spectral moment for /t/ targets (
p
= .001) and the lowest /t/-/k/ difference (
p
= .010).

Conclusion
Middorsum palatal stops may occur in children with repaired CLP in response to limited anterior oral cavity space due to restricted (or collapsed) maxillary arches. First spectral moment characteristics of middorsum palatal stops are consistent with backed lingual placement during stop release.
Apolipoprotein A-I helical structure and stability in discoidal high-density lipoprotein (HDL) particles by hydrogen exchange and mass spectrometry
Authors: Sevugan Chetty Palaniappan , Mayne Leland , Kan Zhong-Yuan , Lund-Katz Sissel , Englander S. Walter , Phillips Michael C. 
Published: June 2012

To understand high-density lipoprotein (HDL) structure at the molecular level, the location and stability of α-helical segments in human apolipoprotein (apo) A-I in large (9.6 nm) and small (7.8 nm) discoidal HDL particles were determined by hydrogen-deuterium exchange (HX) and mass spectrometry methods. The measured HX kinetics of some 100 apoA-I peptides specify, at close to amino acid resolution, the structural condition of segments throughout the protein sequence and changes in structure and stability that occur on incorporation into lipoprotein particles. When incorporated into the large HDL particle, the nonhelical regions in lipid-free apoA-I (residues 45–53, 66–69, 116–146, and 179–236) change conformation from random coil to α-helix so that nearly the entire apoA-I molecule adopts helical structure (except for the terminal residues 1–6 and 237–243). The amphipathic α-helices have relatively low stability, in the range 3–5 kcal/mol, indicating high flexibility and dynamic unfolding and refolding in seconds or less. A segment encompassed by residues 125–158 exhibits bimodal HX labeling indicating co-existing helical and disordered loop conformations that interchange on a time scale of minutes. When incorporated around the edge of the smaller HDL particle, the increase in packing density of the two apoA-I molecules forces about 20% more residues out of direct contact with the phospholipid molecules to form disordered loops, and these are the same segments that form loops in the lipid-free state. The region of disc-associated apoA-I that binds the lecithin-cholesterol acyltransferase enzyme is well structured and not a protruding unstructured loop as reported by others.
