Congruence of Readiness to Change, Self-Efficacy, and Decisional Balance for Physical Activity and Dietary Fat Reduction
Authors: Boudreaux Edwin D. , Wood Karen B. , Mehan Dan , Scarinci Isabel , Taylor Cindy L. Carmack , Brantley Phillip J. 
Published: November 2011

Purpose. The current study examines the relations between decisional balance and self-efficacy variables on stage of change between the behaviors of avoiding dietary fat and increasing exercise. Design. A cross-sectional design was used. Setting. The current study took place in public primary care clinics from four sites across Louisiana. Clinics were associated with teaching hospitals and located in urban and rural areas. Subjects. Subjects included 515 adult outpatients, 60% African-American, 81% women, and 43% married. The age ranged from 18 to 87 years old, and the mean age was 45 (SD = 14). Patients were predominantly low-income (mean household income of $490 per month) and uninsured (71%). Measures. Standard questionnaires were given to assess stage of change, decisional balance, and self-efficacy for exercise and dietary fat reduction. Results. Although the χ2 analysis revealed that dietary fat and exercise stage of change were significantly related, Pearson χ2 (df = 16) = 74.30, p < .001, 35% of the sample was stage incongruent between behaviors (e.g., a significant percentage of exercise maintainers were precon-templators for reducing dietary fat). Only 27% of the sample was in the same stage for both behaviors. Correlations and multivariate analyses of variance (MANOVAs) indicated that relationships between behaviors were similar to those found previously within behaviors; however, the effect sizes were markedly attenuated. Conclusions. These results have implications for healthcare providers working with weight management. Accurate assessment of readiness for change for both exercise and dietary fat consumption is critical. For many patients, readiness for change differs dramatically between the two behaviors, and interventions may need to be tailored more precisely. Providers may need to use more active, behaviorally focused interventions for the more advanced behavior while simultaneously implementing more cognitively focused interventions for the less advanced one.
Ethnic Differences among Correlates of Physical Activity in Women
Authors: Mâsse Louise C. , Anderson Cheryl B. 
Published: November 2011

Purpose. This study investigated differences between two ethnic minority groups on five hypothesized correlates of physical activity (beliefs about the value of physical activity, normative modeling, perceived barriers, outcome expectations, and self-efficacy). Design. A cross-sectional sample consisting of 246 African American and Hispanic women 40 to 70 years of age was used. Multivariate analysis of covariance including interactions with education and income was used. Results. A three-way interaction (ethnicity by education by income) was significant for perceived barriers. In addition, a two-way interaction (education by income) was significant for normative modeling. Conclusions. Ethnic differences by education and income were associated with some correlates of physical activity; therefore, it is important to consider this diversity when designing physical-activity interventions for minority women.

Published: November 2011

Purpose. This study tested a conceptual model based on research supporting the relationship between the predictors of hardiness, supervisor support, and group cohesion and the criterions of job stress and job satisfaction and between the predictor of job stress and the criterion of job satisfaction. Design. The study employed a cross-sectional research design. Survey data were collected as part of the baseline measures assessed prior to an organizational hardiness intervention. Setting. Worksite of Dell Computer Corporation in Austin, Texas. Subjects. The subjects included 160 full-time Dell employees recruited from a convenience sample representing nine work groups (response rate = 90%). Measures. Hardiness was measured using the Dispositional Resilience Scale (DRS), job stress was measured using the Perceived Work Stress Scale (PWSS), and supervisor support, group cohesion, and job satisfaction were measured using a proprietary employee attitude survey. Results. In the proposed model, high hardiness, supervisor support, and group cohesion were related to lower levels of job stress, which in turn was related to higher levels of job satisfaction. The model also proposed direct paths from hardiness, supervisor support, and group cohesion to job satisfaction. Path analysis was used to examine the goodness of fit of the model. The proposed model was a good fit for the data (χ2[1, N = 160] = 1.85, p = .174) with the exception of the direct path between group cohesion and job satisfaction. Substantial portions of the variances in job stress ( R2 = .19) and job satisfaction (R2 = .44) were accounted for by the predictors. Conclusion. Implications for targeted worksite health promotion efforts to lower job stress and enhance job satisfaction are discussed.
Walking and Bicycling: An Evaluation of Environmental Audit Instruments
Authors: Moudon Anne Vernez , Lee Chanam 
Published: November 2011

Purpose. This paper reviews existing environmental audit instruments used to capture the walkability and bikability of environments. The review inventories and evaluates individual measures of environmental factors used in these instruments. It synthesizes the current state of knowledge in quantifying the built environment. The paper provides health promotion professionals an understanding of the essential aspects of environments influencing walking and bicycling for both recreational and transportation purposes. It serves as a basis to develop valid and efficient tools to create activity-friendly communities. Data Sources. Keyword searches identified journal articles from the computer-based Academic Citation Databases, including the National Transportation Library, the Web of Science Citation Database, and MEDLINE. Governmental publications and conference proceedings were also searched. Study Inclusion and Exclusion Criteria. All instruments to audit physical environments have been included in this review, considering both recreation- and transportation-related walking and bicycling. Excluded are general methods devised to estimate walking and cycling trips, those used in empirical studies on land use and transportation, and research on walking inside buildings. Data Extraction Methods. Data have been extracted from each instrument using a template of key items developed for this review. The data were examined for quality assurance among three experienced researchers. Data Synthesis. A behavioral model of the built environment guides the synthesis according to three components: the origin and destination of the walk or bike trip, the characteristics of the road traveled, and the characteristics of the areas surrounding the trip's origin and destination. These components, combined with the characteristics of the instruments themselves, lead to a classification of the instruments into the four categories of inventory, route quality assessment, area quality assessment, and approaches to estimating latent demand for walking and bicycling. Furthermore, individual variables used in each instrument to measure the environment are grouped into four classes: spatiophysical, spatiobehavioral, spatiopsychosocial, and policy-based. Major Conclusions. Individually, existing instruments rely on selective classes of variables and therefore assess only parts of built environments that affect walking and bicycling. Most of the instruments and individual measures have not been rigorously tested because of a lack of available data on walking and bicycling and because of limited research budgets. Future instrument development will depend on the acquisition of empirical data on walking and bicycling, on inclusion of all three components of the behavioral model, and on consideration of all classes of variables identified.
A Vision for Older Adults and Health Promotion
Authors: Beattie Bonita Lynn , Whitelaw Nancy , Mettler Molly , Turner David 
Published: November 2011

Our rapidly aging population is expected to place heavy demands on all segments of society, particularly the health care resources needed to attend to health concerns associated with aging. Is this a looming crisis, as some predict, or a challenge to use resources more wisely and to help older adults and their caregivers share in the responsibility for health promotion and chronic disease self-management activities? Community-based organizations serving older adults are uniquely positioned to augment health care providers' health promotion counseling activities and to bridge the gap between the research and practice of health promotion in older adults. They already play a crucial role by providing appropriate health promotion education, screening and referral, service planning, and reinforcement to facilitate self-care activities and behavior changes that promote healthy aging. By increasing teamwork across the network of services for the aging, the health sector, public and private organizations, and academe, there is a great opportunity to enhance the health and well-being of all older Americans. If I'd known I was gonna live this long, I'd have taken better care of myself. —Eubie Blake at age 100
L'Analyse des Organisations en Afrique: Un Champ de Recherche Emergent
Authors: Emmanuel Kamdem  
Published: November 2011

L'organisation, concept fondamental en sciences sociales et en sciences de gestion, a fait l'objet d'une littérature abondante qui a permis à l'analyse des organisations de devenir progressivement un champ de recherche dominant. Ce champ de recherche s'est d'abord développé en Amérique du Nord, principalement aux États-Unis, ou a été réalisé les premiers travaux systématiques sur l'organisation ; travaux essentiellement consacrés aux problèmes de fonctionnement des unités de production économique. A lafaveur de /'exportation dans d'autres régions du monde du modèle américain de gestion et des paradigmes qui le sous-tendent, après la deuxième guerre mondiale, /'analyse des organisations a connu desdéveloppements importants en Europe, en Amérique du Sud et en Asie. L'Afrique, longtemps restée en marge de cette évolution, commence son tour à connaître un regain d'intérêt pour l'organisation en tant qu'objet d'étude ; et ce à partir des années quatre-vingt. C'est une situation nouvelle que s'intéresse I'auteur de ce texte en proposant une rejlexion articulée autour de deux axes majeurs. D'une part, effectuer un survol de la littérature sur les organisations en tentant de dégager les principales perspectives d'analyse et, d'autre part, porter un regard sur la production africaine actuelle ajin d'élucider les conditions de son émergence et d'évaluer les possibilités de son développement. L'pertinence de la présente réflexion se justifie par la nécessité de construire un discours à la fois cohérent et réaliste sur l'organisation en Afrique, tout en adoptant une posture à l' attention des discours antérieurs et actuels sur l'organisation ailleurs dans le monde, notamment en Occident.

AbstractBackgroundWith the high prevalence of musculoskeletal disorders (MSDs) for patient care unit workers, prevention efforts through ergonomic practices within units may be related to symptoms associated with typical work‐related MSDs.MethodsWe completed a cross‐sectional survey of patient care workers (n = 1,572) in two large academic hospitals in order to evaluate relationships between self‐reported musculoskeletal pain, work interference due to this pain, and limitations during activities of daily living (functional limitations) and with ergonomic practices and other organizational policy and practices metrics within the unit. Bivariate and multiple logistic regression analyses tested the significance of these associations.ResultsPrevalence of self‐reported musculoskeletal symptoms in the past 3 months was 74% with 53% reporting pain in the low back. 32.8% reported that this pain interfered with their work duties and 17.7% reported functional limitations in the prior week. Decreased ergonomic practices were significantly associated with reporting pain in four body areas (low back, neck/shoulder, arms, and lower extremity) in the previous 3 months, interference with work caused by this pain, symptom severity, and limitations in completing activities of daily living in the past week. Except for low back pain and work interference, these associations remained significant when psychosocial covariates such as psychological demands were included in multiple logistic regressions.ConclusionsErgonomic practices appear to be associated with many of the musculoskeletal symptoms denoting their importance for prevention efforts in acute health care settings.

Representativity and networks of Marine Protected Areas
Authors: Rice Jake , Houston Kim 
Published: November 2011

ABSTRACTThrough recent Decisions of the Convention on Biological Diversity (CBD), States have agreed to establish networks of Marine Protected Areas (MPAs), and that representativity is a necessary feature of the networks.There is extensive literature on the intent of these commitments and scientific guidance on network design. The guidance specifies that to have representativity captured in a network requires that a suitable biogeographical classification exists and that areas which ‘represent’ the biogeographical subdivisions are included. However, no operational guidance has been provided on how to determine that a subdivision is adequately ‘represented’ by a protected area.This paper looks at the management and conservation functions expected to be served by representative MPAs, including an ‘insurance policy’ function, a ‘benchmark’ or natural control function, and a ‘seed stock’ function.The scales at which marine ecological processes typically operate are reviewed, as a basis for determining the scales of MPAs needed to provide these functions.It is concluded that representative MPAs at the spatial scales of the interactions of key top predators and forage fish generally should ensure spatial scales large enough to give protection to the other processes as well.To ensure the key functions are served, the representative MPAs also should have sufficient protection that human pressures do not alter the characteristics of these ecological processes.Copyright © Her Majesty the Queen in Right of Canada 2011.

Electroactive Self‐Assembled Monolayers of Unique Geometric Structures by Using Rigid Norbornylogous Bridges
Authors: Darwish Nadim , Eggers Paul K. , Da Silva Paulo , Zhang Yi , Tong Yujin , Ye Shen , Gooding J. Justin , Paddon‐Row Michael N. 
Published: November 2011

AbstractHerein, we describe the synthesis of straight (S) and L‐shaped (L) norbornylogous bridges (NBs) with an anthraquinone moiety at the distal end as the redox‐active head group and two thiol feet at the proximal end, by which the molecules assemble on gold surfaces. The NB molecules were shown to form self‐assembled monolayers (SAMs) with a well‐behaved surface redox process. The SAMs were characterized by using in situ IR spectroscopy, cyclic voltammetry, scanning tunnelling microscopy and electrochemical impedance spectroscopy. The surface selection rules associated with the IR band intensities allowed the estimation of the position of the anthraquinone moiety with respect to the surface and the tilt of the bridge with respect to the surface normal, both in pure and diluted monolayers. It is shown that the S‐ and L‐NBs hold the plane of the anthraquinone moiety close to the surface normal or the surface tangent, respectively. Neither NB molecule changes its orientation if spaced by diluents on the surface. The difference in the structure of the S‐ and L‐NB SAMs provides a suitable framework for the investigation of factors that govern electron transfer of anthraquinone moieties across self‐assembled monolayers with limited structural ambiguity, as compared with the commonly used structurally flexible alkanethiol monolayers.
Current drugs in systemic lupus erythematosus
Authors: Yu Yiyun , La Cava Antonio 
Published: November 2011

AbstractSystemic lupus erythematosus (SLE) is an autoimmune disease with heterogeneous presentation and clinical manifestations. These aspects represent a problem in the treatment of the disease. Nonspecific medications for SLE that include antimalarials, corticosteroids, and cytotoxic drugs improve the prognosis of SLE yet carry significant side effects. Therefore, new targeted therapies that block pathways involved in the pathogenesis of SLE have been developed as possible additions to the standard management of the disease. This work reviews the current therapies and novel approaches in the treatment of SLE. Drug Dev Res 72:561–572, 2011. ©2011 Wiley Periodicals, Inc.
The lymphocyte potassium channels Kv1.3 and KCa3.1 as targets for immunosuppression
Authors: Lam Jenny , Wulff Heike 
Published: November 2011

AbstractThe voltage‐gated Kv1.3 and the calcium‐activated KCa3.1 potassium channel modulate many calcium‐dependent cellular processes in immune cells, including T‐cell activation and proliferation and have therefore been proposed as novel therapeutic targets for immunomodulation. Kv1.3 is highly expressed in CCR7− effector memory T cells and is emerging as a target for T‐cell‐mediated diseases like multiple sclerosis, rheumatoid arthritis, type‐1 diabetes mellitus, allergic contact dermatitis, and psoriasis. In contrast, KCa3.1 is expressed in CCR7+ naive and central memory T cells, as well as in mast cells, macrophages, dedifferentiated vascular smooth muscle cells, fibroblasts, vascular endothelium, and airway epithelium. Given this expression pattern, KCa3.1 is a potential therapeutic target for conditions ranging from inflammatory bowel disease, multiple sclerosis, arthritis, and asthma to cardiovascular diseases such as atherosclerosis and post‐angioplasty restenosis. Results from animal studies have been supportive of the therapeutic potential of both Kv1.3 and KCa3.1 blockers and have also not shown any toxicities associated with pharmacological Kv1.3 and KCa3.1 blockade. To date, two compounds targeting Kv1.3 are in preclinical development, but so far, no Kv1.3 blocker has advanced into clinical trials. KCa3.1 blockers, on the other hand, have been evaluated in clinical trials for sickle cell anemia and exercise‐induced asthma, but have so far not shown efficacy. However, the trial results support KCa3.1 as a safe therapeutic target and hopefully will enable clinical trials for other medical conditions that might benefit from KCa3.1 blockade.

Published: November 2011

AbstractSubstitution of the naphthalene ligand in [CpRu(C10H8)]+ (1; Cp = cyclopentadienyl ligand) by other arenes occurs upon heating or visible‐light irradiation and gives complexes [CpRu(arene)]+ [arene = C6HnMe6–n, C6H5OH, C6H5OMe, C6H4(OMe)2, indene, 2,2‐paracyclophane] in 70–90 % yield. The reaction rate increases with coordinating ability of the solvent, CH2Cl2 < THF/CH2Cl2 < Me2CO, and counterion, [B(3,5‐(CF3)2C6H3)4]– < PF6– < BF4– < CF3SO3–. Acceptor or bulky substituents in the incoming arene slow down the exchange. Complexes with acceptor arenes C6H5COMe, C6H5COOH, and C6H4(COOH)2 were obtained by the exchange reaction in water. Complexes [CpRu(η6‐cycloheptatriene)]+ and [CpRu(η6‐cyclooctatetraene)]+ were obtained by irradiation of 1 with the corresponding cyclic polyenes. A similar reaction with α‐phellandrene is accompanied by dehydrogenation to give [CpRu(cymene)]+. Cation 1 reacts with 2‐naphthoic acid anion to give the zwitterionic complexes [CpRu]+[C10H7COO]– in which the [CpRu]+ fragment coordinates either at the substituted or unsubstituted ring. Upon protonation and subsequent irradiation, both isomers convert into [CpRu(C10H7COOH)]+ in which the metal atom coordinates only to the unsubstituted ring. The structures of [CpRu(p‐xylene)][PF6], [CpRu(2,2‐paracyclophane)][PF6], [CpRu(C6H5COOH)][BF4], and [CpRu(cymene)][BPh4] were determined by X‐ray diffraction.
Ionic Additives and Weak Magnetic Fields in the Thermal Decomposition of Octacarbonyldicobalt – Tools To Control the Morphology of Cobalt Nanoparticles

Published: November 2011

AbstractIn the presence of ionic compounds, the thermal decomposition of octacarbonyldicobalt, Co2(CO)8, in an inert solvent leads exclusively to ϵ‐Co nanocubes. The ionic species can be added directly or generated in situ by a chemical reaction between an additive and the precursor or between two additives. The additional presence of an inhomogeneous magnetic field leads to disc‐shaped crystalline nanoparticles, which assemble to chains.
Electrochemical Reductive Deprotonation of an Imidazole Ligand in a Bipyridine Tricarbonyl Rhenium(I) Complex
Authors: Zeng Qiang , Messaoudani Mahdi , Vlček Antonín , Hartl František 
Published: November 2011

AbstractThe reduction pathway of fac‐[ReI(imH)(CO)3(bpy)]+ was studied in situ by UV/Vis/NIR–IR spectroelectrochemistry with an OTTLE cell. The complex underwent 1e– reduction of the 2,2′‐bipyridine (bpy) ligand and intramolecular electron transfer, which resulted in the conversion of the axial imidazole (imH) ligand to 3‐imidazolate (3‐im–). This step was followed by two bpy‐based 1e– reductions to ultimately produce five‐coordinate [Re(CO)3(bpy)]– and free 3‐im–. The identity of the reduction product fac‐[Re(3‐im–)(CO)3(bpy)] has been proven by partial chemical deprotonation of the parent complex followed by IR spectroelectrochemistry. This is the first time that the reductive electrochemical conversion of metal‐coordinated imidazole to terminal 3‐imidazolate has been observed.
