State Power to Define Jurisdiction
States should have much broader authority to decline jurisdiction over federal claims. The normative considerations supporting this doctrine of “reverse abstention” have been developed in previous work. But what of the Constitution? The traditional reading, reflected in existing precedent, asserts that the Supremacy Clause, Article III, and perhaps Article I operate together to create an inflexible obligation for state courts to hear federal claims. This reading is misguided. The Supremacy Clause contains no jurisdictional obligation of its own force, but only gives supreme effect to other validly enacted federal laws. And no other clause provides the authority to impose such an obligation on the states. Suggestions to the contrary are based on an overly cramped version of originalism that fails to account for the exigencies of constitutional compromise and ratification
Immediate Effects of Cervical Spine Manipulation on Gait Parameters in Individuals with and without Mechanical Neck Pain
Purpose: The purpose of this study was to determine 1) if there were any differences in gait parameters between participants with mechanical neck pain and those without and 2) if cervical spine manipulation has an immediate effect on these gait parameters.
Methods: Twenty participants with mechanical neck pain and twenty participants without neck pain were randomly assigned into either the sham or manipulation group. The two intervention groups participated in walking across a GAITRite Walkway that recorded gait parameters such as stride length, cadence and step width before and after cervical spine manipulation. The participants walked at their own cadence with 1) head forward, 2) head turning up and down and 3) head turning side-to-side. T-tests were used to assess 8 different gait parameters between groups before and after intervention and to assess cervical range of motion differences between groups and before and after intervention in the sagittal, transverse and coronal plane. Repeated measures two-way ANOVA was used to assess pre and post intervention differences between groups in the NDI, NPRS and GROC. Post-hoc pair-wise corrections were to be used in the event of significant interactions between treatments and groups. Statistical significant was set at p \u3c0.05.
Results: Compared to pain-free subjects, the T-tests demonstrated that patients with mechanical neck pain had smaller values of gait velocity, stride length, and step length before any treatment was provided (p\u3c0.05). Prior to treatment, T-tests revealed no differences in cervical ROMs between persons with and without neck pain for the sagittal plane motion (P = 0.182); frontal plane motion (P = 0.347); and transverse plane (P = 0.181). The 2-way ANOVAs revealed a significant “group” main effect in gait velocity during normal walking (P=0.004), indicating participants with neck pain increased their velocity whereas participants without neck pain demonstrated decreased velocity regardless of intervention given. A separate independent t-test indicated that there was a significant interaction in GROC score changes between treatment and group (P =0.043).
Conclusion: Our study indicated that patients with neck pain walked more slowly with shorter stride length and step length. . These gait characteristics observed might be strategies to compensate for gait instability, which involves proprioceptive deficits from the cervical spine. Additionally participants with neck pain increased their gait velocity post intervention whereas participants without neck pain demonstrated decreased velocity post intervention (manipulation/sham). While our results suggest TJM did improve gait velocity in those with neck pain post manipulation, we did not see significant changes in other gait parameters. This study suggests that clinicians should consider the assessment and management of gait performance, balance and risk of falling in patients with acute mechanical neck pain
Investigating the effectiveness of spatial frequencies to the left and right of central vision during reading:Evidence from reading times and eye movements
Printed words are complex visual stimuli containing a range of different spatial frequencies, and several studies have suggested that various spatial frequencies are effective for skilled adult reading. But while it is well known that the area of text from which information is acquired during reading extends to the left and right of each fixation, the effectiveness of spatial frequencies falling each side of fixation has yet to be determined. To investigate this issue, we used a spatial frequency adaptation of the gaze-contingent moving-window paradigm in which sentences were shown to skilled adult readers either entirely as normal or filtered to contain only low, medium, or high spatial frequencies except for a window of normal text around each point of fixation. Windows replaced filtered text either symmetrically 1 character to the left and right of each fixated character, or asymmetrically, 1 character to the left and 7 or 13 to the right, or 1 character to the right and 7 or 13 to the left. Reading times and eye-movement measures showed that reading performance for sentences presented entirely as normal generally changed very little with filtered displays when windows extended to the right but was often disrupted when windows extended to the left. However, asymmetrical windows affected performance on both sides of fixation. Indeed, increasing the leftward extent of windows from 7 to 13 characters produced decreases in both reading times and fixation durations, suggesting that reading was influenced by the spatial frequency content of leftward areas of text some considerable distance from fixation. Overall, the findings show that while a range of different spatial frequencies can be used by skilled adult readers, the effectiveness of spatial frequencies differs for text on each side of central vision, and may reflect different roles played by these two areas of text during reading
Views of young people with chronic conditions on transition from pediatric to adult health services
PURPOSE: This study sought to identify and describe the views of young people with chronic conditions about the transition from pediatric to adult services. METHODS: Q methodology was used to identify young people’s views on transition. A set of 39 statements about transition was developed from an existing literature review and refined in consultation with local groups of young people. Statements were printed onto cards and a purposive sample of 44 young people with chronic health conditions was recruited, 41 remaining in the study. The young people were asked to sort the statement cards onto a Q-sort grid, according to their opinions from “strongly disagree” to “strongly agree.” Factor analysis was used to identify shared points of view (patterns of similarity between individual’s Q-sorts). RESULTS: Four distinct views on transition were identified from young people: (1) “a laid-back view of transition;” (2) “anxiety about transition;” (3) “wanting independence and autonomy during transition;” and (4) “valuing social interaction with family, peers, and professionals to assist transition.” CONCLUSIONS: Successful transition is likely to be influenced by how young people view the process. Discussing and understanding young people’s views and preferences about transition should help clinicians and young people develop personalized planning for transition as a whole, and more specifically the point of transfer, leading to effective and efficient engagement with adult care
Metabolic Requirements of Farmers/Ranchers Performing Simulated Occupational Tasks: Recommendations for Cardiovascular Rehabilitation
Current ACSM guidelines for cardiac rehabilitation (rehab) return to work state that exercise training should mimic the muscle groups, movements, and energy systems utilized in a patient’s occupational tasks. The aims of this study were to evaluate the metabolic costs of typical farming/ranching tasks, determine the pattern of movement and muscle groups involved in these tasks, and determine the approximate duration of these tasks. Methods: Participants (n=29) were employed in the farming/ranching field and ranged in aged from 18-57 years. The participants performed four tasks: loading 10 hay bales, digging a fence post hole, filling eight seed hoppers, and shoveling grain. Results: Ranges for mean metabolic equivalent (MET) levels of the tasks were 5.9-7.6 while respiratory exchange ratio (RER) values ranged from .85-.93. Mean times (min:sec) for task duration were 1:42-3:34. Conclusion: MET levels recorded in this study are in agreement with the Compendium of Physical Activities for farming tasks and meet the standard requirements for cardiovascular training in cardiac rehab (~ 8 METS). However, these tasks are of high intensity and require an exercise prescription based on specificity of training for the muscle groups and energy systems involved. In accordance to ACSM guidelines, this study includes recommendations for exercise prescription specific to supervised resistance training appropriate for a farmer/rancher population in cardiac rehab settings
Unveiling Order behind Complexity: Coexistence of Ferromagnetism and Bose-Einstein Condensation
We present an algebraic framework for identifying the order parameter and the
possible phases of quantum systems that is based on identifying the local
dimension of the quantum operators and using the SU(N) group representing
the generators of generalized spin-particle mappings. We illustrate this for
=3 by presenting for any spatial dimension the exact solution of the
bilinear-biquadratic =1 quantum Heisenberg model at a high symmetry point.
Through this solution we rigorously show that itinerant ferromagnetism and
Bose-Einstein condensation may coexist.Comment: 5 pages, 1 psfigur
Exclusive breastfeeding and its effect on growth of Malawian infants: results from a cross-sectional study
Abstract
Background:
For the optimal nutrition of children under 2 years of age, it is considered important that they be exclusively breastfed for the first 6 months before being given complementary food.
Aims and Objectives:
A cross-sectional nutritional baseline survey was undertaken in 2011 in the Kasungu and Mzimba Districts of Malawi to assess the nutritional status of children under 2 years of age and its determinants in order to prepare a nutrition education intervention programme. The intention of this study was to assess the nutritional status of infants aged 0–<6 months with regard to food intake.
Methods:
Interviews were conducted on randomly selected families with children under 2 years; anthropometric measurements were obtained from mothers and their children. Only infants between 0 and <6 months were selected for analysis (n = 196). An ANCOVA test was performed on age of the infant with mothers’ height and weight as covariates.
Results:
Prevalence of stunting (infants’ length-for-age Z-score (LAZ) <−2SD) was 39%, wasting (WLZ <−2SD) 2%, and underweight (WAZ <−2SD) 13%. Of the infants under 6 months, 43% were exclusively breastfed. Predominant breastfeeding and mixed breastfeeding were less common (21% and 36%, respectively). The ANCOVA confirmed the association between exclusive breastfeeding and LAZ and WAZ: exclusively breastfed infants had a higher mean (SE) LAZ (−1·13, 0·12) and WAZ (−0·41, 0·13) than infants not being exclusively breastfed (−1·59, 0·11, and −0·97, 0·11, respectively). There was no overall significant association between breastfeeding practice and WLZ.
Conclusion:
Exclusive breastfeeding of infants under 6 months is associated with higher mean LAZ and WAZ. Promotion of exclusive breastfeeding in low-income countries is important in preventing growth retardation
