Published: September 2014

Abstract
In this paper, some relations between L
p-spaces on locally compact groups are found. Applying these results proves that for a locally compact group G, the convolution Banach algebras L
p(G) ∩ L
1(G) (1 < p ≤ ∞), and A
p(G) ∩ L
1(G) (1 < p < ∞) are amenable if and only if G is discrete and amenable.

Authors: He Zhimin , Shen Jianhua 
Published: September 2014

Abstract
In this paper, by using a fixed-point theorem in cones to study the boundary value problem for a class of quadratic mixed type of delay differential equations with eigenvalue, the sufficient condition of existence of their solutions is derived. The main results in this paper are the generalization and improvement of those existing ones.

{{C + D\prod\limits_{i = 1}^k {x_{n - 2i} } }}, n = 0,1,2, \ldots ,$$ where A, B are nonnegative real numbers, C,D > 0 and l, k are nonnegative integers such that l ≤ k.
Perov type results in gauge spaces and their applications to integral systems on semi-axis
Authors: Novac Adela , Precup Radu 
Published: September 2014

Abstract
In this paper we present Perov type fixed point theorems for contractive mappings in Gheorghiu’s sense on spaces endowed with a family of vector-valued pseudo-metrics. Applications to systems of integral equations are given to illustrate the theory. The examples also prove the advantage of using vector-alued pseudo-metrics and matrices that are convergent to zero, for the study of systems of equations.
On comparison of ℓ-stable vector optimization results
Authors: Dvorská Marie , Pastor Karel 
Published: September 2014

Abstract
Two papers with similar optimality conditions were published by I. Ginchev, and by D. Bednařík and K. Pastor independently in Nonlinear Analysis in 2011. We compare these results. We also show the equivalence of two definitions of ℓ-stability of vector functions. Moreover, we generalize another result given by I. Ginchev and V. I. Ivanov [J. Math. Anal. Appl. 340 (2008), 646–657] and compare it with the previously mentioned optimality conditions.
Core-free, rank two coset geometries from edge-transitive bipartite graphs
Authors: Saedeleer Julie , Leemans Dimitri , Mixer Mark , Pisanski Tomaž 
Published: September 2014

Abstract
It is known that the Levi graph of any rank two coset geometry is an edge-transitive graph, and thus coset geometries can be used to construct many edge transitive graphs. In this paper, we consider the reverse direction. Starting from edge-transitive graphs, we construct all associated core-free, rank two coset geometries. In particular, we focus on 3-valent and 4-valent graphs, and are able to construct coset geometries arising from these graphs. We summarize many properties of these coset geometries in a sequence of tables; in the 4-valent case we restrict to graphs that have relatively small vertex-stabilizers.
Continuity of separately continuous mappings
Authors: Mirmostafaee Alireza 
Published: September 2014

Abstract
By means of a topological game, a class of topological spaces which contains compact spaces, q-spaces and W-spaces was defined in [BOUZIAD, A.: The Ellis theorem and continuity in groups, Topology Appl. 50 (1993), 73–80]. We will show that if Y belongs to this class, every separately continuous function f: X × Y → Z is jointly continuous on a dense subset of X × Y provided that X is σ-β-unfavorable and Z is a regular weakly developable space.

Limiting behavior of generalized delayed average of random sequence
Authors: Wang Zhong-zhi , Chen Wen-bo 
Published: September 2014

Abstract
Let (ξ
n)n∈N be a sequence of arbitrarily dependent random variables, and let $$T_{a_n ,k_n }$$ be delayed sums. By virtue of the notion of asymptotic delayed log-likelihood ratio and Laplace transformation, the almost sure limiting behavior of the generalized delayed averages $$\frac{1}
{{k_n }}T_{a_n ,k_n }$$ is investigated, of which the results generalize and improve some work of Liu.
A randomized controlled dual-center trial on shunt complications in idiopathic normal-pressure hydrocephalus treated with gradually reduced or “fixed” pressure valve settings
Authors: Sæhle Terje , Farahmand Dan , Eide Per Kristian , Tisell Magnus , Wikkelsö Carsten 
Published: September 2014

Object
This study was undertaken to investigate whether a gradual reduction of the valve setting (opening pressure) decreases the complication rate in patients with idiopathic normal-pressure hydrocephalus (iNPH) treated with a ventriculoperitoneal (VP) shunt.

Methods
In this prospective double-blinded, randomized, controlled, dual-center study, a VP shunt with an adjustable valve was implanted in 68 patients with iNPH, randomized into two groups. In one group (the 20–4 group) the valve setting was initially set to 20 cm H2O and gradually reduced to 4 cm H2O over the course of the 6-month study period. In the other group (the 12 group), the valve was kept at a medium pressure setting of 12 cm H2O during the whole study period. The time to and type of complications (hematoma, infection, and mechanical problems) as well as overdrainage symptoms were recorded. Symptoms, signs, and outcome were assessed by means of the iNPH scale and the NPH grading scale.

Results
Six patients in the 20–4 group (22%) and 7 patients in the 12 group (23%) experienced a shunt complication; 9 had subdural hematomas, 3 mechanical obstructions, and 1 infection (no significant difference between groups). The frequency of overdrainage symptoms was significantly higher for a valve setting ≤ 12 cm H2O compared with a setting > 12 cm H2O. The 20–4 group had a higher improvement rate (88%) than the 12 group (62%) (p = 0.032). There was no significant relationship between complications and body mass index, the use of an antisiphon device, or the use of anticoagulants.

Conclusions
Gradual lowering of the valve setting to a mean of 7 cm H2O led to the same rate of shunt complications and overdrainage symptoms as a fixed valve setting at a mean of 13 cm H2O but was associated with a significantly better outcome.

Role of the protection forest in integrated risk management
Half the Swiss forests play a role in protecting against natural hazards. After a historical overview of the strategy of protection against natural hazards and of the development of the protection function of the forest, the authors, basing the analysis on the modern definition of integrated risk management, demonstrate, on the basis of evidence, that protection forests may be considered as a protective measure for integrated risk management. Some complementary analysis is necessary, including the assessment and quantification of the protection function, strengthening the role of forest planning, quantifying the cost-benefit ratio, and clearly defining the legal responsibility of the forest owner.

Published: September 2014

The present work investigates the antibacterial activity of silver nanoparticles (Ag-NPs) synthesized by biological method using Sargassum wightii. The fresh live seaweed was collected from the Mandapam coast of Tamilnadu, India. Solvent extract was prepared using acetone, petroleum ether and methanol. Aqueous extract of the seaweed was also used for the synthesis of silver Ag-NPs. Seaweed extract is used as a reducing agent of 2mM silver nitrate solution for the synthesis of Ag-NPs. Periodical monitoring of reaction mixture was done using UV-vis spectroscopy at 300-750 nm. The scanning electron microscopy (SEM) of the sample confirms the presence of Ag-NPs. The antibacterial activity of solvent extract was done by Minimal inhibitory concentration (MIC) assay. The methanol extract of the seaweed at a concentration of 250µg/ml exhibited potent antimicrobial activity against the test microorganism. The zone of inhibition ranging from 8-14 mm was observed with different extracts. The antibacterial activity of the synthesized Ag-NPs against the organism was also done by MIC test. The MIC of Ag-NPs was found to be 130µg/ml for all pathogenic microorganisms selected for the study. The zone of inhibition against Bacillus cereus, Bacillus anhtracis, Staphylococcus aureus and Vibrio alginoyticus were found to be 10, 8, 10 and 9 mm, respectively. The synthesized Ag-NPs exhibited significant antimicrobial activity against the selected microorganisms than the solvent extract of seaweed.DOI: http://dx.doi.org/10.3329/icpj.v3i10.20337 International Current Pharmaceutical Journal, September 2014, 3(10): 322-325
Instrumental Activities of Daily Living Performance Among People With Parkinson’s Disease Without Dementia
Authors: Foster Erin R. 
Published: September 2014

Abstract
OBJECTIVE. To investigate the performance of cognitively demanding instrumental activities of daily living (IADLs) among people with Parkinson’s disease (PD) without dementia.
METHOD. Seventy-seven participants with PD and 57 participants without PD underwent standardized, performance-based IADL evaluation using the Performance Assessment of Self-care Skills. Activity performance was rated for independence, adequacy, and safety.
RESULTS. The PD group had lower independence and adequacy scores than the non-PD group for almost every activity. Medication management, shopping, and sharp utensil use were the activities most sensitive to group differences. In the PD group, older age, lower Mini-Mental State Examination scores, and decreased motor function were associated with poorer IADL performance.
CONCLUSIONS. People with relatively early and mild PD demonstrated measurable deficits in the performance of cognitively demanding IADLs. This work highlights the importance of using objective assessments of IADL function to detect early functional changes in people with PD.
Effects of Early Intervention on Mental or Neuromusculoskeletal and Movement-Related Functions in Children Born Low Birthweight or Preterm: A Meta-Analysis
Authors: Park Hae Yean , Maitra Kinsuk , Achon Jacqueline , Loyola Evelyn , Rincón María 
Published: September 2014

Abstract
OBJECTIVE. We conducted a meta-analysis to examine the association between early intervention and mental or neuromusculoskeletal and movement-related functions of children born low birthweight (LBW) or preterm.
METHOD. The meta-analysis included 16 studies that yielded 97 effects. Q and I2 values were used to determine heterogeneity. Publication bias was evaluated using Egger’s regression intercept test and a funnel plot.
RESULTS. The association between early intervention and either mental or neuromusculoskeletal and movement-related functions yielded a significant but small effect size (d = .219, p &lt; .0001). Heterogeneity was statistically insignificant.
CONCLUSION. Participation in early intervention programs addressing mental or neuromusculoskeletal and movement-related functions in children born LBW or preterm results in significant improvements in these areas.
Using Mirror Therapy in the Home Environment: A Case Report
Authors: Nilsen Dawn M. , DiRusso Theresa 
Published: September 2014

AbstractOBJECTIVE. Mirror therapy (MT) is a potential intervention to improve function after stroke. How to apply this intervention in practice is not clear. This case report illustrates the feasibility and effectiveness of a self-administered home-based MT program.METHOD. A home-based MT program was practiced over 5 wk. The participant was encouraged to use MT for 30 min 5×/wk. Therapist contact occurred 1×/wk to monitor performance. An independent evaluator administered three outcome measures pre- and postintervention: Upper Extremity Sensory and Pain sections of the Fugl-Meyer Assessment; Jebsen–Taylor Test of Hand Function, and the Manual Ability Measure–20.RESULTS. The participant engaged in a mean of 39.23 (±7.44) min of MT per day and used a variety of the recommended activities. Change scores indicated improvement on all of the included outcome measures.CONCLUSION. This case report suggests that a predominantly self-administered home-based MT program is feasible and effective at improving function after stroke.
Parents’ Explanatory Models and Hopes for Outcomes of Occupational Therapy Using a Sensory Integration Approach
Authors: Cohn Ellen S. , Kramer Jessica , Schub Jamie A. , May-Benson Teresa 
Published: September 2014

AbstractPURPOSE. To describe parents’ concerns and hopes for their children who would be receiving occupational therapy using a sensory integration approach.METHOD. Content analysis of 275 parental responses to three open-ended questions on developmental–sensory history intake forms.FINDINGS. Parents’ descriptions of why they sought for their children were categorized into four overarching concerns about their children’s challenges: self-regulation, interacting with peers, participating in skilled motor activities, and self-confidence. Parents often linked these concerns together, revealing explanatory models of how they make sense of potential relationships among their children’s challenges and how these challenges affect occupational performance. Parents hoped occupational therapy would help their children develop self-understanding and frustration tolerance to self-regulate their behavior in socially acceptable ways.IMPLICATIONS. Assessment and intervention should explicitly focus on links among self-regulation, social participation, skills, and perceived competence to address parents’ expectations.

Published: September 2014

AbstractThis article explores the use of the postrotary nystagmus (PRN) test for children younger than current norms (children 4.0 yr–8.11 yr). In the first study, 37 children ages 4–9 yr were examined in the standard testing position and in an adult-held adapted position to determine whether holding a child affected the reflex. Because the position did not affect the reflex, in the second study, PRN in 44 children ages 2 mo–47 mo was compared with published normative mean raw scores for 44 children age 5 yr to determine whether norms for older children were applicable to younger children. No statistically significant differences were found between &lt;4-yr-old and 5-yr-old children, suggesting that the PRN test can be used in infants and toddlers with valid comparison to current norms for 4-yr-olds on the Sensory Integration and Praxis Tests (4.0 yr–8.11 yr). Future research exploring the predictive value of this measure is warranted.
Activities and Adaptation in Late-Life Depression: A Qualitative Study
Authors: Leibold Mary Lou , Holm Margo B. , Raina Ketki D. , Reynolds Charles F. , Rogers Joan C. 
Published: September 2014

Abstract
OBJECTIVE. We sought to understand activity choices of older adults when they were depressed.
METHOD. Each community-dwelling participant (n = 27) completed one semistructured interview while in recovery for at least 3 mo. but less than 7 mo. Transcripts were coded to identify relevant themes.
RESULTS. Six themes emerged that explained activities participants continued while depressed, and four themes described activities they stopped.
CONCLUSION. Older adults maintained many instrumental activities of daily living while depressed, and some actively adapted activities so they could continue them. Some intentionally stopped activities to direct limited energy to their highest priority activities. To guide effective intervention, it is critical for occupational therapy practitioners to complete a client-centered qualitative assessment to understand what and, most important, why activities are continued or stopped. Each theme for activities continued and activities stopped lends itself to intervention strategies.
Systematic Review of Studies on Measurement Properties of Instruments for Adults Published in the American Journal of Occupational Therapy, 2009–2013
Authors: Yuen Hon K. , Austin Sarah L. 
Published: September 2014

Abstract
OBJECTIVE. We describe the methodological quality of recent studies on instrument development and testing published in the American Journal of Occupational Therapy (AJOT).
METHOD. We conducted a systematic review using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist to appraise 48 articles on measurement properties of assessments for adults published in AJOT between 2009 and 2013.
RESULTS. Most studies had adequate methodological quality in design and statistical analysis. Common methodological limitations included that methods used to examine internal consistency were not consistently linked to the theoretical constructs underpinning assessments; participants in some test–retest reliability studies were not stable during the interim period; and in several studies of reliability and convergent validity, sample sizes were inadequate.
CONCLUSION. AJOT’s dissemination of psychometric research evidence has made important contributions to moving the profession toward the American Occupational Therapy Association’s Centennial Vision. This study’s results provide a benchmark by which to evaluate future accomplishments.
Composition of a Vision Screen for Servicemembers With Traumatic Brain Injury: Consensus Using a Modified Nominal Group Technique
Authors: Radomski Mary Vining , Finkelstein Marsha , Llanos Imelda , Scheiman Mitchell , Wagener Sharon Gowdy 
Published: September 2014

Abstract
Vision impairment is common in the first year after traumatic brain injury (TBI), including among service members whose brain injuries occurred during deployment in Iraq and Afghanistan. Occupational therapy practitioners provide routine vision screening to inform treatment planning and referral to vision specialists, but existing methods are lacking because many tests were developed for children and do not screen for vision dysfunction typical of TBI. An expert panel was charged with specifying the composition of a vision screening protocol for servicemembers with TBI. A modified nominal group technique fostered discussion and objective determinations of consensus. After considering 29 vision tests, the panel recommended a nine-test vision screening that examines functional performance, self-reported problems, far–near acuity, reading, accommodation, convergence, eye alignment and binocular vision, saccades, pursuits, and visual fields. Research is needed to develop reliable, valid, and clinically feasible vision screening protocols to identify TBI-related vision disorders in adults.
Moving Toward 2017: Progress in Rehabilitation Intervention Effectiveness Research
Authors: Doucet Barbara M. , Woodson Anne , Watford Monica 
Published: September 2014

Abstract
Halfway into the 10-yr American Occupational Therapy Association Centennial Vision initiative, occupational therapy has made notable progress in establishing itself as a science-driven profession. Through the diligent work of many talented occupational therapy scholars, 42 research studies exploring interventions used in rehabilitation research were published in the past 5 years. A variety of both novel and established intervention strategies were investigated using diverse research designs and measurement tools. A predominant number of studies were conducted with the poststroke population. Moving forward to 2017 and building on our success, we can recognize our full potential by fostering knowledge translation, expanding participant numbers, exploring less-studied populations, increasing the volume of systematic reviews published, and reporting occupation-centered outcomes, the unique and defining component of our profession.
Children and Youth Instrument Development and Testing Articles Published in theAmerican Journal of Occupational Therapy,2009–2013: A Content, Methodology, and Instrument Design Review
Authors: Brown Ted , Bourke-Taylor Helen 
Published: September 2014

AbstractWe extracted 35 articles published between January 2009 and September 2013 in the American Journal of Occupational Therapy (AJOT) that focused on children and youth instrument development and testing, summarized study details and traits of the 37 measures reported in them, and then critiqued the measures. Most of the articles contained Level III evidence (one-group nonrandomized and noncontrolled). The most common types of reliability reported in the articles were internal consistency, test–retest reliability, and interrater reliability; the most frequent types of validity reported were discriminant validity and construct validity. Most pediatric assessment tools were designed for school-age children between ages 5 and 12 yr. The two most common purposes for the assessments were reported as descriptive and discriminative. The continued publication of instruments that measure children and youth participation in meaningful occupations and life roles in home, school, and community environments is recommended.
Development and Preliminary Reliability of a Multitasking Assessment for Executive Functioning After Concussion
Authors: Smith Laurel B. , Radomski Mary Vining , Davidson Leslie Freeman , Finkelstein Marsha , Weightman Margaret M. , McCulloch Karen L. , Scherer Matthew R. 
Published: September 2014

Abstract
OBJECTIVES. Executive functioning deficits may result from concussion. The Charge of Quarters (CQ) Duty Task is a multitask assessment designed to assess executive functioning in servicemembers after concussion. In this article, we discuss the rationale and process used in the development of the CQ Duty Task and present pilot data from the preliminary evaluation of interrater reliability (IRR).
METHOD. Three evaluators observed as 12 healthy participants performed the CQ Duty Task and measured performance using various metrics. Intraclass correlation coefficient (ICC) quantified IRR.
RESULTS. The ICC for task completion was .94. ICCs for other assessment metrics were variable.
CONCLUSION. Preliminary IRR data for the CQ Duty Task are encouraging, but further investigation is needed to improve IRR in some domains. Lessons learned in the development of the CQ Duty Task could benefit future test development efforts with populations other than the military.
