The Butz Stops Here: Why the Food Movement Needs to Rethink Agricultural History
From the 1890s to the 1930s, rural Americans played a vital role in radical leftist politics. While specialists know this history well, the public tends to know a folk history, written by figures associated with contemporary food movements. This folk history rests on several key myths, which cover different periods of modern history from the New Deal to the present. This essay challenges these myths to reveal the causes and extent of the suffering endured by rural families in the 20th century, which in turn, decimated the populist left. A reconsideration of the history of agricultural policy will help food-system reformers develop a more radical and effective vision for rural Americ
Evaluation of a German Version of the Physical Dimensions of the Health Assessment Questionnaire in Patients with Rheumatoid Arthritis
Ankylosing spondylitis and sarcoidosis — Coincidence or association?
We report a 25-year-old woman presenting with sarcoidosis and bilateral sacroiliitis. Her sarcoidosis related symptoms (malaise, cough and dyspnoea) improved dramatically under treatment with steroids but severe back pain persisted. Only seven similar cases have been described over the last 40 years and the question of a possible association between the two diseases has been raised. However, prevalence data from the literature and the apparent lack of genetic links are better arguments for coincidence than for association
Quantum cryptography protocols robust against photon number splitting attacks for weak laser pulses implementations
We introduce a new class of quantum quantum key distribution protocols,
tailored to be robust against photon number splitting (PNS) attacks. We study
one of these protocols, which differs from the BB84 only in the classical
sifting procedure. This protocol is provably better than BB84 against PNS
attacks at zero error.Comment: 4 pages, 2 figure
COMPARISON OF THE VALIDITY AND RELIABILITY OF SELF-REPORTED ARTICULAR INDICES
Our objective was to compare the validity and reliability of three formats for self-administered articular indices assessing pain (PAI) or swelling (SAI). Fifty-five patients with rheumatoid arthritis were asked to mark the degree of pain on a list of 16 joints (PAI list), to mark ‘painful joints' on a mannequin presenting 42 joints (PAI diagram), and to mark ‘swollen or tender joints' on a mannequin presenting 38 joints (SAI diagram). The test-retest reliability (intraclass correlation coefficient) ranged from 0.63 (SAI diagram) to 0.67 (PAI diagram) and 0.85 (PAI list). The correlation with clinical parameters was strongest for the PAI list and the SAI diagram. The association of the SAI diagram with clinical parameters increased with omission of the less reliable toe joints and/or weighting for joint size according to Lansbury. As expected, the short and weighted SAI diagram correlated more strongly with the physician-derived swollen joint count (r = 0.49), C-reactive protein (r = 0.49) and erythrocyte sedimentation rate (r = 0.41) than did the PAI list whereas the PAI list correlated more strongly with physician-derived tender joint count (r = 0.43), global pain measured on a numerical rating scale (r = 0.57) and the Health Assessment Questionnaire (r = 0.49) than did the SAI diagram. We concluded that patients' rating of tender and swollen joints on a mannequin diagram and calculation of a 26-joint and weighted articular index produces an excellent estimate of total joint inflammation, which may be useful in clinical, health services and epidemiological research. An articular index calculated from ratings of pain degree of 16 joints or joint groups may provide complementary informatio
Does a Muscle Strenght Index Provide complementary Information to traditional Disease Acivity Variables in Patients with rheumatoid Arthritis
Developing core sets for persons following amputation based on the International Classification of Functioning, Disability and Health as a way to specify functioning
Amputation is a common late stage sequel of peripheral vascular disease and diabetes or a sequel of accidental trauma, civil unrest and landmines. The functional impairments affect many facets of life including but not limited to: Mobility; activities of daily living; body image and sexuality. Classification, measurement and comparison of the consequences of amputations has been impeded by the limited availability of internationally, multiculturally standardized instruments in the amputee setting. The introduction of the International Classification of Functioning, Disability and Health (ICF) by the World Health Assembly in May 2001 provides a globally accepted framework and classification system to describe, assess and compare function and disability. In order to facilitate the use of the ICF in everyday clinical practice and research, ICF core sets have been developed that focus on specific aspects of function typically associated with a particular disability. The objective of this paper is to outline the development process for the ICF core sets for persons following amputation. The ICF core sets are designed to translate the benefits of the ICF into clinical routine. The ICF core sets will be defined at a Consensus conference which will integrate evidence from preparatory studies, namely: (a) a systematic literature review regarding the outcome measures of clinical trails and observational studies, (b) semi-structured patient interviews, (c) international experts participating in an internet-based survey, and (d) cross-sectional, multi-center studies for clinical applicability. To validate the ICF core sets field-testing will follow. Invitation for participation: The development of ICF Core Sets is an inclusive and open process. Anyone who wishes to actively participate in this process is invited to do so
Establishing score equivalence of the Functional Independence Measure motor scale and the Barthel Index, utilising the International Classification of Functioning, Disability and Health and Rasch measurement theory
Introduction: Two widely used outcome measures to assess functioning in neurological rehabilitation are the Functional Independence Measure (FIM™) and the Barthel Index. The current study aims to establish the equivalence of the total score of the FIM™ motor scale and the Barthel Index through the application of the International Classification of Functioning, Disability and Health, and Rasch measurement theory. Methods: Secondary analysis of a large sample of patients with stroke, spinal cord injury, and multiple sclerosis, undergoing rehabilitation was conducted. All patients were assessed at the same time on both the FIM™ and the Barthel Index. The International Classification of Functioning, Disability and Health Linking Rules were used to establish conceptual coherency between the 2 scales, and the Rasch measurement model to establish an exchange of the total scores. Results: Using the FIM™ motor scale, items from both scales linked to the International Classification of Functioning, Disability and Health d4 Mobility or d5 Self-care chapters. Their co-calibration satisfied the assumptions of the Rasch model for each of 3 diagnostic groups. A ceiling effect was observed for the Barthel Index when contrasted against the FIM™ motor scale. Conclusion: Having a Rasch interval metric to transform scores between the FIM™ motor scale and Barthel Index is valuable for monitoring functioning, meta-analysis, quality audits and hospital benchmarking
