STAIRS/VS has been installed on an IBM System/370-B5 in the computer centre of the central institute for scientific and technical information (ZINTI) in Sofia since 1975. Besides literature documentation, STAIRS/VS is also used for project documentation in order to supervise projects and their progress. Two types of data banks result from this problem in two parts differing in structure. Internal data as well as external data from magnetic tape service enter the STAIRS/VS data bank. The processing of texts in Cyrillic applied here for the first time is completely new for STAIRS/VS operation. Hence certain modifications for STAIRS/VS were made: STAIRS/VS was supplemented by a series of programmes for project supervision. The data acquisition as well as the change or supplementation of the documents already stored in STAIRS/VS mainly run via VIDEO/370. Besides the STAIRS/VS standard information on high-speed printers or on magnetic tape, special printing forms were developed. Parties interested in STAIRS/VS are supplied with a SDI service produced in batch process based on magnetic tape service; it is made in special size. The appropriate data banks are accordingly available for on-line research. (orig.) [de

Walking up and down stairs is a common and important activity of daily living. Women with fibromyalgia often show a reduced ability to perform this task.The objective of this study was to evaluate the test-retest reliability of stair negotiation tasks and to assess the impact of fibromyalgia symptoms on the ability to negotiate stairs.Forty-two women with fibromyalgia participated in this descriptive correlational study. The relevance of the stair negotiation (both walking up and down) was evaluated by assessing its association with the revised version of the fibromyalgia impact questionnaire (FIQ-R) and other health-related variables. Test-retest reliability was also analyzed. The main outcome measures were time spent walking up and down stairs and impact of fibromyalgia, quality of life, number of falls, weight, and lower limb strength and endurance.The intraclass correlation coefficient (ICC) for stair descent was 0.929 whereas that for ascent was 0.972. The score in these tests correlated significantly with the total score for the FIQ-R and the score for many of dimensions and symptoms: that is, physical function, overall impact of fibromyalgia, pain, energy, stiffness, restorative sleep, tenderness, self-perceived balance problems, and sensitivity.Given the importance of the stair negotiation as activity of daily living and the high reliability, both stair ascent and descent tasks may be useful as outcome measures in studies on patients with fibromyalgia.

Stairs represent a barrier to safe locomotion for some older adults, potentially leading to the adoption of a cautious gait strategy that may lack fluidity. This strategy may be characterized as unsmooth; however, stair negotiation smoothness has yet to be quantified. The aims of this study were to assess age- and task-related differences in head and body center of mass (COM) acceleration patterns and smoothness during stair negotiation and to determine if smoothness was associated with the timed "Up and Go" (TUG) test of functional movement. Motion data from nineteen older and twenty young adults performing stair ascent, stair descent, and overground straight walking trials were analyzed and used to compute smoothness based on the log-normalized dimensionless jerk (LDJ) and the velocity spectral arc length (SPARC) metrics. The associations between TUG and smoothness measures were evaluated using Pearson's correlation coefficient (r). Stair tasks increased head and body COM acceleration pattern differences across groups, compared to walking (p < 0.05). LDJ smoothness for the head and body COM decreased in older adults during stair descent, compared to young adults (p ≤ 0.015) and worsened with increasing TUG for all tasks (-0.60 ≤ r ≤ -0.43). SPARC smoothness of the head and body COM increased in older adults, regardless of task (p < 0.001), while correlations showed improved SPARC smoothness with increasing TUG for some tasks (0.33 ≤ r ≤ 0.40). The LDJ outperforms SPARC in identifying age-related stair negotiation adaptations and is associated with performance on a clinical test of gait. Copyright © 2018 Elsevier B.V. All rights reserved.

Mirror, Mirror by the Stairs: The Impact of Mirror Exposure on Stair versus Elevator Use in College Students.

Hodgin, Katie L; Graham, Dan J

2016-01-01

Previous research has indicated that self-awareness-inducing mirrors can successfully incite behaviors that align with one's personal values, such as helping others. Other research has found a large discrepancy between the high percentage of young adults who report valuing the healthfulness of physical activity (PA) and the low percentage who actually meet PA participation standards. However, few studies have examined how mirror exposure and both perceived and actual body size influence highly valued PA participation among college students. The present study assessed stair versus elevator use on a western college campus and hypothesized that mirror exposure would increase the more personally healthy transportation method of stair use. In accordance with previous research, it was also hypothesized that males and those with a lower body mass index (BMI) would be more likely to take the stairs, and that body size distorting mirrors would impact the stair-elevator decision. One hundred sixty-seven students (51% male) enrolled in an introductory psychology course were recruited to take a survey about their "transportation choices" at an indoor campus parking garage. Participants were individually exposed to either no mirror, a standard full-length mirror, or a full-length mirror manipulated to make the reflected body size appear either slightly thinner or slightly wider than normal before being asked to go to the fourth floor of the garage for a survey. Participants' choice of floor-climbing method (stairs or elevator) was recorded, and they were administered an Internet-based survey assessing demographic information, BMI, self-awareness, perceived body size, and other variables likely to be associated with stair use. Results from logistic regression analyses revealed that participants who were not exposed to a mirror [odds ratios (OR) = 0.37, 95% CI: 0.14-0.96], males (OR = 0.33, 95% CI: 0.13-0.85), those with lower BMI (OR = 0.84, 95% CI: 0.71-0.99), those

This study was designed to determine whether engagement in stair taking can be increased in a worksite setting through the provision of an employer-sponsored, behavior-based incentive system in which employees (members) accumulate points that can be redeemed for merchandise. ChipRewards implemented stair utilization in one employer as a part of a larger health incentive engagement program. Using an AB (baseline-intervention) design, members (N = 216) were observed for 6 months (6.17.10 to 12.14.10 or 129 weekdays after excluding 52 weekend days) before the intervention (baseline) and after 6 months (1.1.11 to 6.30.11 with the same number of weekdays) of implementation. Members were 84% female, 51% Caucasian, 48% African American, 3% Hispanic, and 45 years average age. The number of total stair transactions for all members for all days monitored increased from 5,070 to 38,900, and the average number of stair transactions per day rose from 39 to 301, representing over a 600% increase. The overall cost of incentives for stair utilization was $3,739.30 or $17.55 per member on average. This study supports that stair usage in the workplace is a viable way to increase physical activity. This study adds to existing research that attempted to increase stair utilization through promotion only by adding a behavioral reinforcement strategy. Finally, this study demonstrates that a physical activity among employees at the worksite can be increased with minimal relative cost.

2001-09-01

To demonstrate the usefulness of computer simulation techniques in the investigation of pediatric stair falls. Since stair falls are a common falsely reported injury scenario in child abuse, our specific aim was to investigate the influence of stair characteristics on injury biomechanics of pediatric stair falls by using a computer simulation model. Our long-term goal is to use knowledge of biomechanics to aid in distinguishing between accidents and abuse. A computer simulation model of a 3-year-old child falling down stairs was developed using commercially available simulation software. This model was used to investigate the influence that stair characteristics have on biomechanical measures associated with injury risk. Since femur fractures occur in unintentional and abuse scenarios, biomechanical measures were focused on the lower extremities. The number and slope of steps and stair surface friction and elasticity were found to affect biomechanical measures associated with injury risk. Computer simulation techniques are useful for investigating the biomechanics of stair falls. Using our simulation model, we determined that stair characteristics have an effect on potential for lower extremity injuries. Although absolute values of biomechanical measures should not be relied on in an unvalidated model such as this, relationships between accident-environment factors and biomechanical measures can be studied through simulation. Future efforts will focus on model validation.

Whole-body angular momentum during stair ascent and descent.

Silverman, Anne K; Neptune, Richard R; Sinitski, Emily H; Wilken, Jason M

2014-04-01

The generation of whole-body angular momentum is essential in many locomotor tasks and must be regulated in order to maintain dynamic balance. However, angular momentum has not been investigated during stair walking, which is an activity that presents a biomechanical challenge for balance-impaired populations. We investigated three-dimensional whole-body angular momentum during stair ascent and descent and compared it to level walking. Three-dimensional body-segment kinematic and ground reaction force (GRF) data were collected from 30 healthy subjects. Angular momentum was calculated using a 13-segment whole-body model. GRFs, external moment arms and net joint moments were used to interpret the angular momentum results. The range of frontal plane angular momentum was greater for stair ascent relative to level walking. In the transverse and sagittal planes, the range of angular momentum was smaller in stair ascent and descent relative to level walking. Significant differences were also found in the ground reaction forces, external moment arms and net joint moments. The sagittal plane angular momentum results suggest that individuals alter angular momentum to effectively counteract potential trips during stair ascent, and reduce the range of angular momentum to avoid falling forward during stair descent. Further, significant differences in joint moments suggest potential neuromuscular mechanisms that account for the differences in angular momentum between walking conditions. These results provide a baseline for comparison to impaired populations that have difficulty maintaining dynamic balance, particularly during stair ascent and descent. Copyright © 2014 Elsevier B.V.

Stair-climbing is a key component of rehabilitation therapies for children with physical disabilities. This paper reports on the design of a system, Musical Stairs, to provide auditory feedback during stair-climbing therapies. Musical Stairs is composed of two foot-mounted inertial sensors, a step detection algorithm, and an auditory feedback response. In Phase 1, we establish its clinical feasibility via a Wizard-of-Oz AB/BA cross-over design with 17 children, aged 4-6 years, having diverse diagnoses and gait abilities. Self-, therapist- and blinded-observer reports indicated increased motivation with auditory feedback. Phase 2 describes the construction of a database comprised of synchronized video and inertial data associated with 1568 steps up and down stairs completed by 26 children aged 4-6 years with diverse diagnoses and gait. Lastly, in Phase 3, data from 18 children in the database were used to train a rule-based step detection algorithm based on local minima in the acceleration profile and the foot's swing angle. A step detection rate of 96% [SD=3%] and false positive rate of 6% [SD=5%] were achieved with an independent test set (n=8). Recommendations for future development and evaluation are discussed.

2007-07-01

Physical activity (PA) is a health behavior that most Americans do not participate in at recommended levels. We sought to increase PA by use of motivational signs in selected buildings. Because physical environments are known to influence PA, the relationship of building characteristics and stair usage was also assessed. One pre- and two post-intervention observations were conducted. The proportion of those using the stairs increased from baseline to the second data collection, (chi2 = 39.31, p < 0.01) and baseline to a final data collection (chi2 = 10.1, p < 0.01). Built environment factors, including steps to the next higher floor and the number of floors in the building were consistent predictors of stair use. With signs positioned, the visibility of the stairs while standing in front of elevators became a significant predictor of stair usage. Motivational signs and characteristics of built environments are associated with increased stair usage.

Does perceived steepness deter stair climbing when an alternative is available?

Science.gov (United States)

Eves, Frank F; Thorpe, Susannah K S; Lewis, Amanda; Taylor-Covill, Guy A H

2014-06-01

Perception of hill slant is exaggerated in explicit awareness. Proffitt (Perspectives on Psychological Science 1:110-122, 2006) argued that explicit perception of the slant of a climb allows individuals to plan locomotion in keeping with their available locomotor resources, yet no behavioral evidence supports this contention. Pedestrians in a built environment can often avoid climbing stairs, the man-made equivalent of steep hills, by choosing an adjacent escalator. Stair climbing is avoided more by women, the old, and the overweight than by their comparators. Two studies tested perceived steepness of the stairs as a cue that promotes this avoidance. In the first study, participants estimated the steepness of a staircase in a train station (n = 269). Sex, age, height, and weight were recorded. Women, older individuals, and those who were heavier and shorter reported the staircase as steeper than did their comparison groups. In a follow-up study in a shopping mall, pedestrians were recruited from those who chose the stairs and those who avoided them, with the samples stratified for sex, age, and weight status. Participants (n = 229) estimated the steepness of a life-sized image of the stairs they had just encountered, presented on the wall of a vacant shop in the mall. Pedestrians who avoided stair climbing by choosing the escalator reported the stairs as steeper even when demographic differences were controlled. Perceived steepness may to be a contextual cue that pedestrians use to avoid stair climbing when an alternative is available.

We introduced a wheel-based stair-climbing robot with a hopping mechanism for stairclimbing. The robot, consisting of two body parts connected by springs, climbed stairs quickly, softly, and economically by using the vibration of a two-degrees-of-freedom system. In the future, we intend to shorten the required tread length by controlling the wire tension and minimizing the body length to realize a practical stair-climbing robot.

Research on Dynamics and Stability in the Stairs-Climbing of a Tracked Mobile Robot

Full Text Available Aiming at the functional requirement of climbing up the stairs, the dynamics and stability during a tracked mobile robot's climbing of stairs is studied. First, from the analysis of its cross-country performance, the mechanical structure of the tracked mobile robot is designed and the hardware composition of its control system is given. Second, based on the analysis to its stairs-climbing process, the dynamical model of stairs-climbing is established by using the classical mechanics method. Next, the stability conditions for its stairs-climbing are determined and an evaluation method of its stairs-climbing stability is proposed, based on a mechanics analysis on the robot's backwards tumbling during the stairs-climbing process. Through simulation and experiments, the effectiveness of the dynamical model and the stability evaluation method of the tracked mobile robot in stairs-climbing is verified, which can provide design and analysis foundations for the tracked mobile robots' stairs-climbing.

Ground reaction forces and frictional demands during stair descent: effects of age and illumination.

Science.gov (United States)

Christina, Kathryn A; Cavanagh, Peter R

2002-04-01

Stair descent is an inherently risky and demanding task that older adults often encounter in everyday life. It is believed that slip between the foot or shoe sole and the stair surface may play a role in stair related falls, however, there are no reports on slip resistance requirements for stair descent. The aim of this study was to determine the required coefficient of friction (RCOF) necessary for safe stair descent in 12 young and 12 older adults, under varied illuminance conditions. The RCOF during stair descent was found to be comparable in magnitude and time to that for overground walking, and thus, with adequate footwear and dry stair surfaces, friction does not appear to be a major determinant of stair safety. Illuminance level had little effect on the dependent variables quantified in this study. However, the older participants demonstrated safer strategies than the young during stair descent, as reflected by differences in the ground reaction forces and lower RCOF.

Biomechanics of stair walking and jumping.

Loy, D J; Voloshin, A S

1991-01-01

Physical activities such as stair walking and jumping result in increased dynamic loading on the human musculoskeletal system. Use of light weight, externally attached accelerometers allows for in-vivo monitoring of the shock waves invading the human musculoskeletal system during those activities. Shock waves were measured in four subjects performing stair walking up and down, jumping in place and jumping off a fixed elevation. The results obtained show that walking down a staircase induced shock waves with amplitude of 130% of that observed in walking up stairs and 250% of the shock waves experienced in level gait. The jumping test revealed levels of the shock waves nearly eight times higher than that in level walking. It was also shown that the shock waves invading the human musculoskeletal system may be generated not only by the heel strike, but also by the metatarsal strike. To moderate the risk of degenerative joint disorders four types of viscoelastic insoles were utilized to reduce the impact generated shock waves. The insoles investigated were able to reduce the amplitude of the shock wave by between 9% and 41% depending on the insole type and particular physical activity. The insoles were more effective in the reduction of the heel strike impacts than in the reduction of the metatarsal strike impacts. In all instances, the shock attenuation capacities of the insoles tested were greater in the jumping trials than in the stair walking studies. The insoles were ranked in three groups on the basis of their shock absorbing capacity.

Staff in hospitals frequently travel between floors and choose between taking the stairs or elevator. We compared the time savings with these two options. Four people aged 26-67 years completed 14 trips ranging from one to six floors, both ascending and descending. We compared the amount of time per floor travelled by stairs and by two banks of elevators. Participants reported their fatigue levels using a modified Borg scale. We performed two-way analysis of variance to compare the log-transformed data, with participant and time of day as independent variables. The mean time taken to travel between each floor was 13.1 (standard deviation [SD] 1.7) seconds by stairs and 37.5 (SD 19.0) and 35.6 (SD 23.1) seconds by the two elevators (F=8.61, p<0.001). The difference in time taken to travel by stairs and elevator equaled about 15 minutes a day. Self-reported fatigue was less than 13 (out of 20) on the Borg scale for all participants, and they all stated that they were able to continue their duties without resting. The extra time associated with elevator use was because of waiting for its arrival. There was a difference in the amount of time taken to travel by elevator depending on the time of day and day of the week. Taking the stairs rather than the elevator saved about 15 minutes each workday. This 3% savings per workday could translate into improved productivity as well as increased fitness.

Ascending stairs is a challenging activity of daily living for many populations. Frontal plane joint dynamics are critical to understand the mechanisms involved in stair ascension as they contribute to both propulsion and medio-lateral stability. However, previous research is limited to understanding these dynamics while initiating stair ascent from a stand. We investigated if initiating stair ascent from a walk with a comfortable self-selected speed could affect the frontal plane lower-extremity joint moments and powers as compared to initiating stair ascent from a stand and if this difference would exist at consecutive ipsilateral steps on the stairs. Kinematics data using a 3-D motion capture system and kinetics data using two force platforms on the first and third stair treads were recorded simultaneously as ten healthy young adults ascended a custom-built staircase. Data were collected from two starting conditions of stair ascent, from a walk (speed: 1.42 ± 0.21 m/s) and from a stand. Results showed that subjects generated greater peak knee abductor moment and greater peak hip abductor moment when initiating stair ascent from a walk. Greater peak joint moments and powers at all joints were also seen while ascending the second ipsilateral step. Particularly, greater peak hip abductor moment was needed to avoid contact of the contralateral limb with the intermediate step by counteracting the pelvic drop on the contralateral side. This could be important for therapists using stair climbing as a testing/training tool to evaluate hip strength in individuals with documented frontal plane abnormalities (i.e. knee and hip osteoarthritis, ACL injury).

1997-07-01

OBJECTIVE: The knee valgus-varus moment and the knee angles were compared between normal level walking and stair climbing. DESIGN: Ten healthy subjects were tested for ascent, descent, and level walking. BACKGROUND: An understanding of the normal valgus-varus motion of the knee during stair climbing is needed to apply biomechanical analysis of stair climbing as a evaluation tool for knee osteoarthritis patients. METHODS: A motion analysis system, three force plates, and a flight of stairs were used to collect kinematic and kinetic data. The knee angles and moments were calculated from the collected kinematic and kinetic data. RESULTS: The knee varus angle for the maximum knee valgus moments in stair climbing was significantly greater than that in level walking. The knee valgus moment was significantly correlated to ground reaction forces and knee valgus-varus angle during stair climbing and level walking. CONCLUSIONS: There is a coupling between the knee valgus-varus motion and flexion-extension motion. Ground reaction forces are the major contributors to the within-subject variation in the knee valgus-varus moment during stair climbing and level walking. The knee valgus-varus angle is a major contributor to the between-subject variation in the knee valgus moment during stair climbing and level walking.

This study tested the effectiveness of a stair use promotion strategy in visible and hidden stairwells during intervention and post intervention follow up. A quasi-experimental study design was used with a 1 week baseline, a 3 week intervention, and post intervention at 2 and 4 weeks in 4 university buildings in San Antonio, Texas with stairwells varying in visibility. Participants were students, faculty, staff, and visitors to the 4 buildings. A total of 8431 observations were made. The intervention incorporated motivational signs with direction to nearby stairwells placed by elevators to promote stair use. Stair and elevator use was directly observed and recorded. Logistic regression analyses were used to test whether stair versus elevator use varied by intervention phase and stairwell visibility. Stair use increased significantly (12% units) during the intervention period and remained above baseline levels during post intervention follow-up. At baseline, visible stairs were 4 times more likely to be used than hidden stairs; however, the increase in stair use during intervention was similar in both types of stairwells. Motivational and directional signage can significantly increase stair use on a university campus. Furthermore, stairwell visibility is an important aspect of stair use promotion.

Stair-climbing capabilities of USU's T3 ODV mobile robot

2001-09-01

A six-wheeled autonomous omni-directional vehicle (ODV) called T3 has been developed at Utah State University's (USU) Center for Self-Organizing and Intelligent Systems (CSOIS). This paper focuses on T3's ability to climb stairs using its unique configuration of 6 independently driven and steered wheels and active suspension height control. The ability of T3, or any similar vehicle, to climb stairs is greatly dependent on the chassis orientation relative to the stairs. Stability criteria is developed for any vehicle dimensions and orientation, on any staircase. All possible yaw and pitch angles on various staircases are evaluated to find vehicle orientations that will allow T3 to climb with the largest margin of stability. Different controller types are investigated for controlling vertical wheel movement with the objective of keeping all wheels in contact with the stairs, providing smooth load transfer between loaded and unloaded wheels, and maintaining optimum chassis pitch and roll angles. A controller is presented that uses feedback from wheel loading, vertical wheel position, and chassis orientation sensors. The implementation of the controller is described, and T3's stair climbing performance is presented and evaluated.

Full Text Available Most individuals with intellectual disabilities (ID demonstrate problems in learning and movement coordination. Consequently, they usually have difficulties in activities such as standing, walking, and stair climbing. To monitor the physical impairments of these children, regular gross motor evaluation is crucial. Straight-line level walking is the most frequently used test of their mobility. However, numerous studies have found that unless the children have multiple disabilities, no significant differences can be found between the children with ID and typically-developed children in this test. Stair climbing presents more challenges than level walking because it is associated with numerous physical factors, including lower extremity strength, cardiopulmonary endurance, vision, balance, and fear of falling. Limited ability in those factors is one of the most vital markers for children with ID. In this paper, we propose a sensor-based approach for measuring stair-walking performance, both upstairs and downstairs, for adolescents with ID. Particularly, we address the problem of sensor calibration to ensure measurement accuracy. In total, 62 participants aged 15 to 21 years, namely 32 typically-developed (TD adolescents, 20 adolescents with ID, and 10 adolescents with multiple disabilities (MD, participated. The experimental results showed that stair-walking is more sensitive than straight-line level walking in capturing gait characteristics for adolescents with ID.

Full Text Available Micro mobile robots (MMRs can operate in rugged, narrow or dangerous regions; thus, they are widely used in numerous areas including surveillance, rescue and exploration. In urban environments, stairs are common obstacles, ones that such robots find difficult to manoeuvre over. The authors analysed the research status of MMRs, particularly in terms of difficulties when performing stair climbing and present a novel type of MMR called the micro flip robot (MFRobot. A support arm subassembly was added to the centre of a wheeled chassis; using this structure, the MFRobot can climb stairs when a flipping mode is utilized. Based on this structure, the authors established a kinematic model of the stair-climbing process and analysed the force conditions for the key status, contributing to the existing knowledge of robot design. An MFRobot prototype was produced and the stair-climbing experiments, as well as experiments on manoeuvring through rubble regions and slope surfaces, were conducted. The results show that the MFRobot can rapidly climb common stairs and can easily manoeuvre through a rubble region. The maximum slope angle the robot can climb was shown to be about 35° for concrete and wooden slope surfaces. In the case where the robot needed to be equipped with sensors, particularly a camera, the camera was equipped on the support arm of robot. The MFRobot prototype weighs 2.5 kg and is easily transportable. This structure can resolve contradictions between portability and performance in terms of overcoming obstacles; in addition, operational effectiveness can be improved using this structure.

Is there sufficient evidence regarding signage-based stair use interventions? A sequential meta-analysis.

Bauman, Adrian; Milton, Karen; Kariuki, Maina; Fedel, Karla; Lewicka, Mary

2017-11-28

The proliferation of studies using motivational signs to promote stair use continues unabated, with their oft-cited potential for increasing population-level physical activity participation. This study examined all stair use promotional signage studies since 1980, calculating pre-estimates and post-estimates of stair use. The aim of this project was to conduct a sequential meta-analysis to pool intervention effects, in order to determine when the evidence base was sufficient for population-wide dissemination. Using comparable data from 50 stair-promoting studies (57 unique estimates) we pooled data to assess the effect sizes of such interventions. At baseline, median stair usage across interventions was 8.1%, with an absolute median increase of 2.2% in stair use following signage-based interventions. The overall pooled OR indicated that participants were 52% more likely to use stairs after exposure to promotional signs (adjusted OR 1.52, 95% CI 1.37 to 1.70). Incremental (sequential) meta-analyses using z-score methods identified that sufficient evidence for stair use interventions has existed since 2006, with recent studies providing no further evidence on the effect sizes of such interventions. This analysis has important policy and practice implications. Researchers continue to publish stair use interventions without connection to policymakers' needs, and few stair use interventions are implemented at a population level. Researchers should move away from repeating short-term, small-scale, stair sign interventions, to investigating their scalability, adoption and fidelity. Only such research translation efforts will provide sufficient evidence of external validity to inform their scaling up to influence population physical activity.

Ledoux, E D; Lawson, B E; Shultz, A H; Bartlett, H L; Goldfarb, M

2015-01-01

This paper evaluates the effectiveness of a powered knee and ankle prosthesis for stair ascent through a metabolic assessment comparing energy expenditure of a single transfemoral amputee subject while ascending stairs with the powered prosthesis relative to his passive daily use device, as well as comparing the kinematics and kinetics obtained with the passive prosthesis to healthy biomechanics. The subject wore a portable system that measured pulmonary gaseous exchange rates of oxygen and carbon dioxide while he ascended stairs with each of the prostheses in alternating tests. The results indicated that the amputee's energy expenditure decreased by 32 percent while climbing with the powered prosthesis as compared to his passive one, and the kinematics and kinetics achieved were representative of healthy biomechanics.

The purpose of this study was to clarify the amount of balance necessary for the independence of transfer and stair-climbing in stroke patients. This study included 111 stroke inpatients. Simple and multiple regression analyses were conducted to establish the association between the FIM ® instrument scores for transfer or stair-climbing and Berg Balance Scale. Furthermore, receiver operating characteristic curves were used to elucidate the amount of balance necessary for the independence of transfer and stair-climbing. Simple and multiple regression analyses showed that the FIM ® instrument scores for transfer and stair-climbing were strongly associated with Berg Balance Scale. On comparison of the independent and supervision-dependent groups, Berg Balance Scale cut-off values for transfer and stair-climbing were 41/40 and 54/53 points, respectively. On comparison of the independent-supervision and dependent groups, the cut-off values for transfer and stair-climbing were 30/29 and 41/40 points, respectively. The calculated cut-off values indicated the amount of balance necessary for the independence of transfer and stair-climbing, with and without supervision, in stroke patients. Berg Balance Scale has a good discriminatory ability and cut-off values are clinically useful to determine the appropriate independence levels of transfer and stair-climbing in hospital wards. Implications for rehabilitation The Berg Balance Scale's (BBS) strong association with transfer and stair-climbing independence and performance indicates that establishing cut-off values is vitally important for the established use of the BBS clinically. The cut-off values calculated herein accurately demonstrate the level of balance necessary for transfer and stair-climbing independence, with and without supervision, in stroke patients. These criteria should be employed clinically for determining the level of independence for transfer and stair-climbing as well as for setting balance training

2011-01-01

Full Text Available This paper represents the relationship between the stability of stairs climbing and the centroid position of the search and rescue robot. The robot system is considered as a mass point-plane model and the kinematics features are analyzed to find the relationship between centroid position and the maximal pitch angle of stairs the robot could climb up. A computable function about this relationship is given in this paper. During the stairs climbing, there is a maximal stability-keeping angle depends on the centroid position and the pitch angle of stairs, and the numerical formula is developed about the relationship between the maximal stability-keeping angle and the centroid position and pitch angle of stairs. The experiment demonstrates the trustworthy and correction of the method in the paper.

Conway, Zachary J; Blackmore, Tim; Silburn, Peter A; Cole, Michael H

2018-06-01

It is well understood that stability during ambulation is reliant upon appropriate control of the trunk segment, but research shows that the rhythmicity of this segment is significantly reduced for people with Parkinson's disease (PD). Given the increased risk associated with stair ambulation, this study investigated whether people with PD demonstrate poorer trunk control during stair ambulation compared with age-matched controls. Trunk accelerations were recorded for twelve PD patients and age-matched controls during stair ascent and descent. Accelerations were used to derive measures of harmonic ratios and root mean square (RMS) acceleration to provide insight into the rhythmicity and amplitude of segmental motion. Compared with what is typically seen during level-ground walking, gait rhythmicity during stair negotiation was markedly reduced for older adults and people with PD. Furthermore, both groups exhibited significantly poorer trunk movements during stair descent compared to stair ascent, suggesting that both populations may face a greater risk of falling during this task. As stair negotiation is a common activity of daily life, the increased risk associated with this task should be considered when working with populations that have an increased risk of falling.

In this paper, we propose a framework in which the behaviour of a pedestrian is predicted based on the characteristics of both the pedestrian and the facility the pedestrian uses. As an example of its application, we develop a model to predict the walking speed of a pedestrian on stairs. We examine the physiology and biomechanics of walking on stairs, and then develop a model that predicts walking speed based on the weight and leg extensor power of the pedestrian, and the gradient of the stai...

The Strange Case of Billy Biswas: Two conflicting realities

Directory of Open Access Journals (Sweden)

Bikki Anupama

2017-09-01

Full Text Available Arun Joshi presents socio-cultural conflicts between two different societies. One society is material driven and backed by the modern state apparatus like police, courts, etc. while the other is subsistence driven and is at the bottom in the hierarchy of the modern state. Indian tribal societies have been exploited right from the colonial period into the post-independence times. These two societies differ as follows: the tribal society lives on subsistence looks at Nature as a space for socio-economic, political, cultural and community, while the urban materialistic world perceives Nature as a resource to be exploited. This primordial difference has manifested as a socio-cultural conflict between these two societies. This may be due to the mutually exclusive and incorrigible nature of their social constructs which trigger perceptual obfuscation of symbiotic living.  What appears to be an objective reality for one appears as subjective to the other and vice versa. This paper studies the strangeness of Billy Biswas, the protagonist of the novel in the socio-cultural milieu of conflicting realities.

Peng, Joshua; Fey, Nicholas P; Kuiken, Todd A; Hargrove, Levi J

2016-02-29

The majority of fall-related accidents are during stair ambulation-occurring commonly at the top and bottom stairs of each flight, locations in which individuals are transitioning to stairs. Little is known about how individuals adjust their biomechanics in anticipation of walking-stair transitions. We identified the anticipatory stride mechanics of nine able-bodied individuals as they approached transitions from level ground walking to stair ascent and descent. Unlike prior investigations of stair ambulation, we analyzed two consecutive "anticipation" strides preceding the transitions strides to stairs, and tested a comprehensive set of kinematic and electromyographic (EMG) data from both the leading and trailing legs. Subjects completed ten trials of baseline overground walking and ten trials of walking to stair ascent and descent. Deviations relative to baseline were assessed. Significant changes in mechanics and EMG occurred in the earliest anticipation strides analyzed for both ascent and descent transitions. For stair descent, these changes were consistent with observed reductions in walking speed, which occurred in all anticipation strides tested. For stair ascent, subjects maintained their speed until the swing phase of the latest anticipation stride, and changes were found that would normally be observed for decreasing speed. Given the timing and nature of the observed changes, this study has implications for enhancing intent recognition systems and evaluating fall-prone or disabled individuals, by testing their abilities to sense upcoming transitions and decelerate during locomotion.

Stair climbing is an activity of daily living that might contribute to increase levels of physical activity (PA). To date, there is no study examining the validity of climbing stairs assessed by self-report. The aim of this study was, therefore, to examine the validity of estimated stair climbing from one question included in a common questionnaire compared to a pattern-recognition activity monitor in older adults. A total of 138 older adults (94 women), aged 65-86 years (70.9 ± 4.7 years), from the IMPACT65 + study participated in this validity study. Estimates of stair climbing were obtained from the European Prospective Investigation into Cancer and Nutrition (EPIC) PA questionnaire. An objective assessment of stair climbing was obtained with the Intelligent Device for Energy Expenditure and Activity (IDEEA) monitor. The correlation between both methods to assess stair climbing was fair (ρ = 0.22, p = 0.008 for PA energy expenditure and ρ = 0.26, p = 0.002 for duration). Mean differences between self-report and the IDEEA were 7.96 ± 10.52 vs. 9.88 ± 3.32 METs-min/day for PA energy expenditure, and 0.99 ± 1.32 vs. 1.79 ± 2.02 min/day for duration (both Wilcoxon test p < 0.001). Results from the Bland-Altman analysis indicate that bias between both instruments were -1.91 ± 10.30 METs-min/day and -0.80 ± 1.99 min/day, and corresponding limits of agreement for the two instruments were from 18.27 to -22.10 METs-min/day and from 3.09 to -4.70 min/day, respectively. Our results indicate that self-reported stair climbing has modest validity to accurately rank old age participants, and underestimates both PAEE and its duration, as compared with an objectively measured method.

Gender differences of sagittal knee and ankle biomechanics during stair-to-ground descent transition.

Hong, Yoon No Gregory; Shin, Choongsoo S

2015-12-01

Falls on stairs often result in severe injury and occur twice as frequently in women. However, gender differences in kinetics and kinematics during stair descent are unknown. Thus, this study aimed to determine whether gender differences of knee and ankle biomechanics exist in the sagittal plane during the stair-to-ground descending transition. It was hypothesized that 1) women would reveal higher ground-toe-trochanter angle and lower ground-toe length during stair-to-ground descent transition than men; and 2) women would reveal lower peak knee extension moment during stair-to-ground descent transition than men. Fifteen men and fifteen women were recruited and performed a stair descent activity. Kinetic and kinematic data were obtained using a force plate and motion capture system. The women performed the stair descent with a lower peak knee extension moment and a peak knee power at the early weight acceptance phase. The women also revealed a higher ground-toe-trochanter angle and a lower ground-toe length, which indicated a more forward position of the lower extremity relative to the toe contact point at both the initial contact and at the time of peak kinematic and kinetic events. This study found that knee and ankle kinematics and kinetics differed significantly between the genders due to differences in ground-toe-trochanter angle. Women have a different stair descending strategy that reduces the demand of the lower extremity muscle function, but this strategy seems to increase the risk of falls. Copyright © 2015 Elsevier Ltd.

Point-of-Decision Signs and Stair Use in a University Worksite Setting: General Versus Specific Messages.

Science.gov (United States)

Eckhardt, Mary R; Kerr, Jacqueline; Taylor, Wendell C

2015-01-01

This study tested the effectiveness of two point-of-decision signs to increase stair use and investigated message content by comparing signs with general and specific messages. This study used a quasi-experimental time series design, including a 2-week baseline period: 2 weeks with a general message and 2 weeks with a specific message. The signs were placed in an eight-story university building. The subjects comprised all adults entering the building. During the study, 2997 observations of stair/elevator choice were made. A stair-prompt sign with a general message and a sign with a specific message served as the interventions. Observers measured stair/elevator choice, demographics, and traffic volume. Logistic regression analyses were employed, adjusting for covariates. The specific sign intervention showed significantly increased odds of stair use compared to baseline (odds ratio [OR] = 2.04, 95% confidence interval [CI] = 1.46-2.84). The odds of stair use were also significantly greater with the specific sign than the general sign (OR = 1.57, 95% CI = 1.13-2.20). Only the specific sign significantly increased stair use. The results indicate that a specific message may be more effective at promoting stair use.

A review of stairway falls and stair negotiation: Lessons learned and future needs to reduce injury.

Science.gov (United States)

Jacobs, Jesse V

2016-09-01

Stairways are a common location for falls, and they result in a disproportionate risk of death or severe injury. Stairway falls are a significant problem across the lifespan and are often coincident with risky behaviors during stair use. The mechanics of successful stair negotiation for healthy young and older adults have been well described. These studies imply that current stair design does not offer an optimal universal design to meet the needs of older adults or people with health conditions. In addition, impaired stair negotiation associates with more than impaired strength, including functional impairments of cognitive load, sensory function and central motor coordination. Identification of behavioral strategies or stairway environments that assist or hinder recovery from a loss of balance on stairs remains incomplete. Therefore, future studies should investigate the mechanisms of balance recovery on stairs as well as the effectiveness of environmental interventions to mitigate stairway falls and injuries. Potential areas for evaluation may include modifying stair dimensions, surfaces, handrails, visual cues, and removing distractors of attention. Studies should also evaluate combinatorial interventions on person-related factors, such as behavioral interventions to decrease risky behaviors during stair use as well as interventions on cognitive, sensory, and motor functions relevant to stair use. Moreover, future studies should take advantage of new technologies to record stair use outside the laboratory in order to identify people or locations at risk for stairway falls. Such studies would inform the potential for broad-spectrum programs that decrease the risk of stairway falls and injuries. Copyright © 2016 The Author. Published by Elsevier B.V.

To investigate lower limb biomechanical strategy during stair walking in patients with diabetes and patients with diabetic peripheral neuropathy, a population known to exhibit lower limb muscular weakness. The peak lower limb joint moments of twenty-two patients with diabetic peripheral neuropathy and thirty-nine patients with diabetes and no neuropathy were compared during ascent and descent of a staircase to thirty-two healthy controls. Fifty-nine of the ninety-four participants also performed assessment of their maximum isokinetic ankle and knee joint moment (muscle strength) to assess the level of peak joint moments during the stair task relative to their maximal joint moment-generating capabilities (operating strengths). Both patient groups ascended and descended stairs slower than controls (pperipheral neuropathy were lower (pperipheral neuropathy compared to controls, and lower at knee only in patients without neuropathy. Operating strengths were higher (pneuropathy during stair descent compared to the controls, but not during stair ascent. Patients with diabetic peripheral neuropathy walk slower to alter gait strategy during stair walking and account for lower-limb muscular weakness, but still exhibit heightened operating strengths during stair descent, which may impact upon fatigue and the ability to recover a safe stance following postural instability.

Enhancing the Trajectory Generation of a Stair-Climbing Mobility System

Science.gov (United States)

Chocoteco, Jose Abel

2017-01-01

Recent advances in mobile robotic technologies have enabled significant progress to be made in the development of Stair-Climbing Mobility Systems (SCMSs) for people with mobility impairments and limitations. These devices are mainly characterized by their ability to negotiate those architectural barriers associated with climbing stairs (curbs, ramps, etc.). The development of advanced trajectory generators with which to surpass such architectural barriers is one of the most important aspects of SCMSs that has not yet been appropriately exploited. These advanced trajectory generators have a considerable influence on the time invested in the stair climbing process and on passenger comfort and, consequently, provide people with physical disabilities with greater independence and a higher quality of life. In this paper, we propose a new nonlinear trajectory generator for an SCMS. This generator balances the stair-climbing time and the user’s comfort and includes the most important constraints inherent to the system behavior: the geometry of the architectural barrier, the reconfigurable nature of the SCMS (discontinuous states), SCMS state-transition diagrams, comfort restrictions and physical limitations as regards the actuators, speed and acceleration. The SCMS was tested on a real two-step staircase using different time-comfort combinations and different climbing strategies to verify the effectiveness and the robustness of the proposed approach.

Stair ascent with an innovative microprocessor-controlled exoprosthetic knee joint.

Bellmann, Malte; Schmalz, Thomas; Ludwigs, Eva; Blumentritt, Siegmar

2012-12-01

Climbing stairs can pose a major challenge for above-knee amputees as a result of compromised motor performance and limitations to prosthetic design. A new, innovative microprocessor-controlled prosthetic knee joint, the Genium, incorporates a function that allows an above-knee amputee to climb stairs step over step. To execute this function, a number of different sensors and complex switching algorithms were integrated into the prosthetic knee joint. The function is intuitive for the user. A biomechanical study was conducted to assess objective gait measurements and calculate joint kinematics and kinetics as subjects ascended stairs. Results demonstrated that climbing stairs step over step is more biomechanically efficient for an amputee using the Genium prosthetic knee than the previously possible conventional method where the extended prosthesis is trailed as the amputee executes one or two steps at a time. There is a natural amount of stress on the residual musculoskeletal system, and it has been shown that the healthy contralateral side supports the movements of the amputated side. The mechanical power that the healthy contralateral knee joint needs to generate during the extension phase is also reduced. Similarly, there is near normal loading of the hip joint on the amputated side.

2018-05-23

Knee pain during stair managing is a common complaint among individuals with PFP and can negatively affect their activities of daily living. Gait modification programs can be used to decrease patellofemoral pain. Immediate effects of a stair descent distal gait modification session that intended to emphasize forefoot landing during stair descent are described in this study. To analyze the immediate effects of a distal gait modification session on lower extremity movements and intensity of pain in women with patellofemoral pain during stair descent. Nonrandomized controlled trial. Sixteen women with patellofemoral pain were allocated into two groups: (1) Gait Modification Group (n = 8); and 2) Control Group (n = 8). The intensity of pain (visual analog scale) and kinematics of knee, ankle, and forefoot (multi-segmental foot model) during stair descent were assessed before and after the intervention. After the gait modification session, there was an increase of forefoot eversion and ankle plantarflexion as well as a decrease of knee flexion. An immediate decrease in patellofemoral pain intensity during stair descent was also observed. The distal gait modification session changed the lower extremity kinetic chain strategy of movement, increasing foot and ankle movement contribution and decreasing knee contribution to the task. An immediate decrease in patellofemoral pain intensity during stair descent was also observed. To emphasize forefoot landing may be a useful intervention to immediately relieve pain in patients with patellofemoral pain during stair descent. Clinical studies are needed to verify the gait modification session effects in medium and long terms.

Stanley Cavell, Classical Hollywood and the Constitution of the Ordinary (With Notes on Billy Wilder

Full Text Available When in his Tanner lectures Stanley Cavell sets out to define Ordinary Language Philosophy or – rather – to explain how it demarcates philosophy as such, he takes up psychoanalytic literary criticism in order to articulate the terms of this task. Yet the constitution of the ordinary, in Cavell, is never quite accessed from within psychoanalysis-cum-literature alone; instead, it takes another relation, that of psychoanalysis and literature to classical Hollywood, for Cavell to address the ordinary in terms of its constitution. I propose to discuss this complex using two films by Billy Wilder as a passageway to Cavell’s analytic procedure.

To Take the Stairs or Not to Take the Stairs? Employing the Reflective–Impulsive Model to Predict Spontaneous Physical Activity

Full Text Available The reflective–impulsive model (RIM has been employed to explain various health behaviors. The present study used RIM to predict a spontaneous physical activity behavior. Specifically, 107 participants (75 females; Mage = 20.6 years, SD = 1.92 years completed measures of (1 reflections about spontaneous physical activity, as indexed by self-report questionnaire; (2 impulse toward physical activity, as indexed by the manikin task; and (3 (state self-control, as indexed by the Stroop task. The dependent variable was whether participants took the stairs or the elevator to the study laboratory. Results revealed reflections toward spontaneous physical activity positively predicted stair-taking. Further, a significant impulse toward physical activity × self-control interaction was observed. This interaction revealed that participants with high self-control who had a high impulse toward PA were more likely to take the stairs than their counterparts with a low impulse toward PA, whereas the opposite was the case for participants with low self-control. However, the impulse × self-control interaction was not significant when employing a self-report measure of trait self-control. Thus, RIM may be a good framework with which to consider spontaneous physical activity, but careful consideration must be given when examining variables within RIM (e.g., the boundary condition of self-control.

Suri, Gaurav; Sheppes, Gal; Leslie, Sara; Gross, James J

2014-12-01

To encourage an increase in daily activity, researchers have tried a variety of health-related communications, but with mixed results. In the present research-using the stair escalator choice context-we examined predictions derived from the Heuristic Systematic Model (HSM), Self Determination Theory (SDT), and related theories. Specifically, we tested whether (as predicted by HSM) signs that encourage heuristic processing ("Take the Stairs") would have greatest impact when placed at the stair/escalator point of choice (when processing time is limited), whereas signs that encourage systematic processing ("Will You Take the Stairs?") would have greatest impact when placed at some distance from the point of choice (when processing time is less limited). We also tested whether (as predicted by SDT) messages promoting autonomy would be more likely to result in sustained motivated behavior (i.e., stair taking at subsequent uncued choice points) than messages that use commands. A series of studies involving more than 9,000 pedestrians provided support for these predictions. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Chen-Wei Pan

Full Text Available Managing stairs is a challenging aspect of daily activities of living for older people. We assessed whether older adults with visual impairment (VI have greater difficulties of managing stairs in daily lives.The study was designed as a community-based cross-sectional study based on a Chinese cohort aged 60 years and older in rural China. Visual acuity (VA was measured in both eyes using a retro-illuminated Snellen chart with tumbling-E optotypes. VI (including blindness was defined as presenting VA of worse than 20/60 in either eye. Having any difficulties in managing stairs was self-reported based on a question drawn from the Barthel Index. Information on participants' socioeconomic status, lifestyle-related factors, diseases histories and medication intake was collected using a questionnaire.The Barthel Index, Activities of Daily Living questionnaire was completed by 4597 (99.7% participants including 2218 men and 2379 women. The age of the participants ranged from 60 to 93 years with a mean of 67.6 ± 6.3 years. In age and gender adjusted models, adults with VI had a higher likelihood of having difficulties in managing stairs (odds ratio [OR] = 2.7; 95% confidence interval [CI] 2.0, 3.7 compared with those without. The association of VI with the likelihood of having difficulties in managing stairs was stronger in older adults who lived alone (OR = 3.2; 95%CI 1.8, 4.5 compared with those who lived with other family members (OR = 2.0; 95%CI 1.3, 4.3. Compared with hypertension, diabetes, obesity and cognitive dysfunction, VI had the greatest impact on people's abilities of managing stairs.VI was associated with an increased likelihood of having difficulties in managing stairs, especially in those who lived alone. However, whether the finding could be extrapolated to other populations warrants further studies as different environmental exposures such as illumination and types of stairs may alter the association observed in this study.

Planning paths through a spatial hierarchy - Eliminating stair-stepping effects

Science.gov (United States)

Slack, Marc G.

1989-01-01

Stair-stepping effects are a result of the loss of spatial continuity resulting from the decomposition of space into a grid. This paper presents a path planning algorithm which eliminates stair-stepping effects induced by the grid-based spatial representation. The algorithm exploits a hierarchical spatial model to efficiently plan paths for a mobile robot operating in dynamic domains. The spatial model and path planning algorithm map to a parallel machine, allowing the system to operate incrementally, thereby accounting for unexpected events in the operating space.

Stair climbing helps to accumulate short bouts of physical activity throughout the day as a strategy for attaining recommended physical activity levels. There exists a need for effective long-term stair-climbing interventions that can be transferred to various worksite settings. The aims of this study were: 1) to evaluate short- and long-term effectiveness of a worksite stair-climbing intervention using an objective measurement of stair climbing and a controlled design; and 2) to perform a process evaluation of the intervention. We performed a controlled before-and-after study. The study was conducted in two corporate buildings of the same company located in Paris (France), between September, 2013 and September, 2014. The status of either "intervention site" or "control site" was assigned by the investigators. Participants were on-site employees (intervention site: n = 783; control site: n = 545 at baseline). Two one-month intervention phases using signs (intervention phase 1) and enhancement of stairwell aesthetics (intervention phase 2) were performed. The main outcome was the change in stair climbing, measured with automatic counters and expressed in absolute counts/day/100 employees and percent change compared to baseline. Qualitative outcomes were used to describe the intervention process. Stair climbing significantly increased at the intervention site (+18.7%) but decreased at the control site (-13.3%) during the second intervention phase (difference between sites: +4.6 counts/day/100 employees, p levels at the intervention site, but a significant difference between sites was found (intervention site vs. control site: +2.9 counts/day/100 employees, p level after the end of the study. This study shows a successful stair-climbing intervention at the worksite. The main barriers to adoption and implementation were related to location and visibility of posters. Process evaluation was useful in identifying these barriers throughout the study, and in

2016-01-01

Intraocular lenses (IOLs) provide distance and near refraction and are becoming the standard for cataract surgery. Multifocal glasses increase variability of toe clearance in older adults navigating stairs and increase fall risk; however, little is known about the biomechanics of stair navigation in individuals with multifocal IOLs. This study compared clearance while ascending and descending stairs in individuals with monofocal versus multifocal IOLs. Eight participants with multifocal IOLs (4 men, 4 women; mean age = 66.5 yr, standard deviation [SD] = 6.26) and fifteen male participants with monofocal IOLs (mean age = 69.9 yr, SD = 6.9) underwent vision and mobility testing. Motion analysis recorded kinematic and custom software-calculated clearances in three-dimensional space. No significant differences were found between groups on minimum clearance or variability. Clearance differed for ascending versus descending stairs: the first step onto the stair had the greatest toe clearance during ascent, whereas the final step to the floor had the greatest heel clearance during descent. This preliminary study indicates that multifocal IOLs have similar biomechanic characteristics to monofocal IOLs. Given that step characteristics are related to fall risk, we can tentatively speculate that multifocal IOLs may carry no additional fall risk.

Stair evacuation simulation based on cellular automata considering evacuees’ walk preferences

International Nuclear Information System (INIS)

Ding Ning; Luh, Peter B.; Zhang Hui; Chen Tao

2015-01-01

As a physical model, the cellular automata (CA) model is widely used in many areas, such as stair evacuation. However, existing CA models do not consider evacuees’ walk preferences nor psychological status, and the structure of the basic model is unapplicable for the stair structure. This paper is to improve the stair evacuation simulation by addressing these issues, and a new cellular automata model is established. Several evacuees’ walk preference and how evacuee’s psychology influences their behaviors are introduced into this model. Evacuees’ speeds will be influenced by these features. To validate this simulation, two fire drills held in two high-rise buildings are video-recorded. It is found that the simulation results are similar to the fire drill results. The structure of this model is simple, and it is easy to further develop and utilize in different buildings with various kinds of occupants. (paper)

Effects of obesity on the biomechanics of stair-walking in children.

Anthropometric characteristics, particularly body mass, are important factors in the development and progression of varus/valgus angular deformities of the knee and have long-term implications including increased risk of osteoarthritis. However, information on how excessive body weight affects the biomechanics of dynamic activities in children is limited. The purpose of this study was to test the hypothesis that during stair-walking lower extremity joint moments normalized to body mass in obese children are greater than those in normal-weight children. Eighteen obese children (10.5±1.5 years, 148±10cm, 56.6±8.4kg) and 17 normal-weight children (10.4±1.3 years, 143±9cm, 36.7±7.5kg) were recruited. A Vicon system and two AMTI force plates were used to record and analyze the kinematics and kinetics of ascending and descending stairs. Significant differences in spatio-temporal, kinematic and kinetic parameters during ascending and descending stairs between obese and normal-weight children were detected. For stair ascent, greater hip abduction moments (+23%; p=0.001) and greater knee extension moments (+20%; p=0.008) were observed. For stair descent, smaller hip extension moment (-52%; p=0.031), and greater hip flexion moments (+25%; p=0.016) and knee extension moments (+15%, p=0.008) were observed for obese subjects. To date, it is unclear if and how the body may adapt to greater joint moments in obese children. Nevertheless, these differences in joint moments may contribute to a cumulative overloading of the joint through adolescence into adulthood, and potentially result in a greater risk of developing knee and hip osteoarthritis.

2012-02-01

Previous research on the biomechanics of stair negotiation has ignored the effect of the approaching speed. We examined if initiating stair ascent with a comfortable self-selected speed can affect the lower-extremity joint moments and powers as compared to initiating stair ascent directly in front of the stairs. Healthy young adults ascended a custom-built staircase instrumented with force platforms. Kinematics and kinetics data were collected simultaneously for two conditions: starting from farther away and starting in front of the stairs and analyzed at the first and second ipsilateral steps. Results showed that for the first step, participants produced greater peak knee extensor moment, peak hip extensor and flexor moments and peak hip positive power while starting from farther away. Also, for both the conditions combined, participants generated lesser peak ankle plantiflexor, greater peak knee flexor moment, lesser peak ankle negative power and greater peak hip negative power while encountering the first step. These results identify the importance of the starting position in experiments dealing with biomechanics of stair negotiation. Further, these findings have important implications for studying stair ascent characteristics of other populations such as older adults. Copyright © 2011 Elsevier B.V. All rights reserved.

Analysis of foot clearance in firefighters during ascent and descent of stairs.

Kesler, Richard M; Horn, Gavin P; Rosengren, Karl S; Hsiao-Wecksler, Elizabeth T

2016-01-01

Slips, trips, and falls are a leading cause of injury to firefighters with many injuries occurring while traversing stairs, possibly exaggerated by acute fatigue from firefighting activities and/or asymmetric load carriage. This study examined the effects that fatigue, induced by simulated firefighting activities, and hose load carriage have on foot clearance while traversing stairs. Landing and passing foot clearances for each stair during ascent and descent of a short staircase were investigated. Clearances decreased significantly (p < 0.05) post-exercise for nine of 12 ascent parameters and increased for two of eight descent parameters. Load carriage resulted in significantly decreased (p < 0.05) clearance over three ascent parameters, and one increase during descent. Decreased clearances during ascent caused by fatigue or load carriage may result in an increased trip risk. Increased clearances during descent may suggest use of a compensation strategy to ensure stair clearance or an increased risk of over-stepping during descent.

Specific effects of a calorie-based intervention on stair climbing in overweight commuters.

Science.gov (United States)

Lewis, Amanda L; Eves, Frank F

2011-10-01

Point-of-choice prompts consistently increase stair climbing; a greater increase in overweight than normal weight individuals was reported in a multi-component worksite campaign. The purpose of this study is to investigate effects of a multi-component campaign, on stair climbing, in a public access setting. In an interrupted-time-series-design, baseline observations (2 weeks) preceded a 2-week point-of-choice prompt. An additional message, positioned at the top of the climb for a further 6-week period, summarised the calorific consequences of a single ascent. Inconspicuous observers recorded traveller's methods of ascent, coded by sex and weight status, twice a week between 08:00 and 09:59. At baseline, the overweight chose stairs less than normal weight individuals. The multi-component campaign targeting weight control reversed this bias, increasing stair climbing only in overweight individuals. The specificity of the effect confirms the appeal of this lifestyle activity for the overweight. The discussion focuses on how intentions to control weight may be converted into behaviour.

In negotiating stairs, low foot clearance increases the risk of tripping and a fall. Foot clearance may be related to physical fitness, which differs between active and sedentary participants, and be acutely affected by exercise. Impaired stair negotiation could be an acute response to exercise. Here we determined acute changes in foot clearances during stair walking in sedentary (n = 15) and physically active older adults (n = 15) after prolonged exercise. Kinematic data were acquired during negotiation with a 3-steps staircase while participants walked at preferred speed, before and after 30 min walking at preferred speed and using a treadmill. Foot clearances were compared before and after exercise and between the groups. Sedentary older adults presented larger (0.5 cm for lead and 2 cm for trail leg) toe clearances in ascent, smaller (0.7 cm) heel clearance in the leading foot in descent, and larger (1 cm) heel clearance in the trailing foot in descent than physically active. Sedentary older adults negotiate stairs in a slightly different way than active older adults, and 30 min walking at preferred speed does not affect clearance in stair negotiation.

Pickle, Nathaniel T; Wilken, Jason M; Aldridge, Jennifer M; Neptune, Richard R; Silverman, Anne K

2014-10-17

Individuals with a unilateral transtibial amputation have a greater risk of falling compared to able-bodied individuals, and falling on stairs can lead to serious injuries. Individuals with transtibial amputations have lost ankle plantarflexor muscle function, which is critical for regulating whole-body angular momentum to maintain dynamic balance. Recently, powered prostheses have been designed to provide active ankle power generation with the goal of restoring biological ankle function. However, the effects of using a powered prosthesis on the regulation of whole-body angular momentum are unknown. The purpose of this study was to use angular momentum to evaluate dynamic balance in individuals with a transtibial amputation using powered and passive prostheses relative to able-bodied individuals during stair ascent and descent. Ground reaction forces, external moment arms, and joint powers were also investigated to interpret the angular momentum results. A key result was that individuals with an amputation had a larger range of sagittal-plane angular momentum during prosthetic limb stance compared to able-bodied individuals during stair ascent. There were no significant differences in the frontal, transverse, or sagittal-plane ranges of angular momentum or maximum magnitude of the angular momentum vector between the passive and powered prostheses during stair ascent or descent. These results indicate that individuals with an amputation have altered angular momentum trajectories during stair walking compared to able-bodied individuals, which may contribute to an increased fall risk. The results also suggest that a powered prosthesis provides no distinct advantage over a passive prosthesis in maintaining dynamic balance during stair walking. Copyright © 2014 Elsevier Ltd.

Stairs to Skałka. From Iconography of Martyrdom of Bishop Stanislaus

Directory of Open Access Journals (Sweden)

Tomasz Węcławowicz

2003-12-01

flights of stairs or ladders leading to the gates from the site where the hired assassins mutilate the body of the Saint. Moreover, nearly in every depiction figures can be seen mounting the stairs towards the open gates. These figures as well as stairs or ladders or gates are not to be found in the texts of The Life o f the Saint because painted and graphic renderings have primarily moralizing aim. The archetype of ‘the stairs to Heaven’ is substantiated in the iconography of the Martyrdom as stairs to the church on Skałka. The interpretation of the stairs to Skałka can therefore be resented as follows: L i t e r a l l y , stairs to the gates are indeed stairs leading to the church ‘Na Skałce’. I n a n a l l e g o r i c a l interpretation, they are the Cross of Christ, who enabled the faithful to ascend to Redemption. A typological unity of steps on Jacob’s ladder and the Cross of Christ has frequently been raised in exegesis, and St. Stanislaus appears here, like every martyr, as alter Christus. In a t r o p o l o g i c a l interpretation, ascending stairs indicate aspiring towards perfection through mounting the steps of deeds. I n a n a n a g o g i c interpretation, these stairs lead to the gates of heavenly Jerusalem.

Full Text Available Background. Fibromyalgia is a chronic disease characterized by widespread pain and other associated symptoms. It has a relevant impact on physical fitness and the ability to perform daily living tasks. The objective of the study was to analyze the step-by-step-performance and the trunk tilt of women with fibromyalgia in the 10-step stair climbing test compared with healthy controls. Methods. A cross-sectional study was carried out. Twelve women suffering from fibromyalgia and eight healthy controls were recruited from a local association. Participants were asked to climb 10 stairs without carrying a load and 10 stairs carrying a load of 5 kg in each hand. Mediolateral trunk tilt was assessed using the “Functional Assessment of Biomechanics (FAB” wireless motion capture device, and the time between steps was assessed via weight-bearing insoles. Results. Trunk tilt in the stair-climbing task carrying a load was significantly higher in women with fibromyalgia when compared to the healthy controls (2.31 (0.63 vs. 1.69 (0.51 respectively. The effect of carrying a load was significantly higher for women with fibromyalgia compared with healthy controls at the intermediate and final part of the task. Discussion. Trunk tilt during stair climbing while carrying a load was higher in women with FM, which could increase the risk of falling. Additionally, women with FM experienced a higher pace slowdown as a consequence of the load, which supports the need of including specific strength and resistance training to physical therapies for this population.

Using a body sensor network to measure the effect of fatigue on stair climbing performance

Bergmann, Jeroen H M; Smith, Ian C H; Mayagoitia, Ruth E

2012-01-01

In terms of self-rated health, the most important activities of daily living are those involving mobility. Of these activities stair climbing is regarded as the most strenuous. A loss of stair climbing ability with age is normally associated with a loss of muscle strength and power, while other factors that influence muscle function, such as fatigue, are often not taken into account. So far no research has been published on how long-lasting fatigue affects activities of daily living, despite the fact that it has been repeatedly proven, in laboratory settings, to influence muscle force production over long periods of time. Technological advances in body sensor networks (BSNs) now provide a method to measure performance during complex real-life situations. In this study the use of a BSN was explored to investigate the effects of long-lasting fatigue on stair climbing performance in 20 healthy adults. Stair climbing performance was measured before and after a fatiguing protocol using a BSN. Performance was defined by temporal and spatial parameters. Long-lasting fatigue was successfully induced in all participants using an exercise protocol. The BSN showed that post-exercise fatigue did not influence stair climbing times (p > 0.2) and no meaningful changes in joint angles were found. No effect on overall stair climbing performance was found, despite a clear presence of long-lasting fatigue. This study shows that physiological paradigms can be further explored using BSNs. Ecological validity of lab-based measurements can be increased by combining them with BSNs. (paper)

Hip osteoarthritis (OA) is often associated with pain and impaired function. Understanding biomechanical alterations in patients with hip OA during challenging activities such as stair use is important to inform treatments. The aim of this study was to determine whether kinematics and kinetics during stair ambulation differed between people with hip OA and healthy controls. Fifteen participants with symptomatic and radiographic hip OA and 15 asymptomatic healthy controls underwent 3-D motion analysis during stair ascent and descent. Trunk, pelvis, and hip kinematics as well as hip kinetics were evaluated. Analyses were performed unadjusted and adjusted for speed and leg length. In both the unadjusted and adjusted analyses, participants with hip OA ascended stairs with less hip range of motion in all three planes and a lower peak external rotation moment compared to controls. In the unadjusted analysis, hip OA participants descended stairs with greater ipsilateral trunk lean, less sagittal plane range of motion, lower peak extension moment, lower peak external rotation moment, and greater hip adduction moment impulse compared to controls. In the adjusted results, peak internal rotation moment and hip adduction moment impulse were greater in hip OA participants compared to controls. Findings show that individuals with hip OA display limited range of hip joint movement, particularly during stair ascent, and overall indicate the use of strategies (e.g., trunk lean; lower peak external rotation moment; higher adduction moment impulse) that implicate altered hip abductor function. Future research is required to further understand the implications of these findings on hip OA. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

2018-06-01

Re-engineering the built environment to influence behaviors associated with physical activity potentially provides an opportunity to promote healthier lifestyles at a population level. Here we present evidence from two quasi-experimental field studies in which we tested a novel, yet deceptively simple, intervention designed to alter perception of, and walking behavior associated with, stairs in an urban area. Our objectives were to examine whether adjusting a stair banister has an influence on perceptions of stair steepness or on walking behavior when approaching the stairs. In study 1, we asked participants (n = 143) to visually estimate the steepness of a set of stairs viewed from the top, when the stair banister was adjusted so that it converged with or diverged from the stairs (± 1.91°) or remained neutral (± 0°). In study 2, the walking behavior of participants (n = 36) was filmed as they approached the stairs to descend, unaware of whether the banister converged, diverged, or was neutral. In study 1, participants estimated the stairs to be steeper if the banister diverged from, rather than converged with, the stairs. The effect was greater when participants were unaware of the adjustment. In study 2, walking speed was significantly slower when the banister diverged from, rather than converged with, the stairs. These findings encourage us to speculate about the potential to economically re-engineer features of the built environment to provide opportunities for action (affordances) that invite physical activity behavior or even promote safer navigation of the environment.

Trunk and lower limb biomechanics during stair climbing in people with and without symptomatic femoroacetabular impingement.

Science.gov (United States)

Hammond, Connor A; Hatfield, Gillian L; Gilbart, Michael K; Garland, S Jayne; Hunt, Michael A

2017-02-01

Femoroacetabular impingement is a pathomechanical hip condition leading to pain and impaired physical function. It has been shown that those with femoroacetabular impingement exhibit altered gait characteristics during level walking and stair climbing, and decreased muscle force production during isometric muscle contractions. However, no studies to-date have looked at trunk kinematics or muscle activation during dynamic movements such as stair climbing in this patient population. The purpose of this study was to compare biomechanical outcomes (trunk and lower limb kinematics as well as lower limb kinetics and muscle activation) during stair climbing in those with and without symptomatic femoroacetabular impingement. Trunk, hip, knee and ankle kinematics, as well as hip, knee and ankle kinetics and muscle activity of nine lower limb muscles were collected during stair climbing for 20 people with clinical and radiographic femoroacetabular impingement and compared to 20 age- and sex-matched pain-free individuals. Those with femoroacetabular impingement ascended the stairs slower (effect size=0.82), had significantly increased peak trunk forward flexion angles (effect size=0.99) and external hip flexion moments (effect size=0.94) and had decreased peak external knee flexion moments (effect size=0.90) compared to the control group. Findings from this study indicate that while those with and without femoroacetabular impingement exhibit many biomechanical similarities when ascending stairs, differences in trunk forward flexion and joint kinetics indicate some important differences. Further longitudinal research is required to elucidate the cause of these differences as well as the clinical relevance. Copyright © 2017 Elsevier Ltd. All rights reserved.

2012-01-01

A novel gait robot enabled nonambulatory patients the repetitive practice of gait and stair climbing. Thirty nonambulatory patients with subacute stroke were allocated to two groups. During 60 min sessions every workday for 4 weeks, the experimental group received 30 min of robot training and 30 min of physiotherapy and the control group received 60 min of physiotherapy. The primary variable was gait and stair climbing ability (Functional Ambulation Categories [FAC] score 0-5); secondary variables were gait velocity, Rivermead Mobility Index (RMI), and leg strength and tone blindly assessed at onset, intervention end, and follow-up. Both groups were comparable at onset and functionally improved over time. The improvements were significantly larger in the experimental group with respect to the FAC, RMI, velocity, and leg strength during the intervention. The FAC gains (mean +/- standard deviation) were 2.4 +/- 1.2 (experimental group) and 1.2 +/- 1.5 (control group), p = 0.01. At the end of the intervention, seven experimental group patients and one control group patient had reached an FAC score of 5, indicating an ability to climb up and down one flight of stairs. At follow-up, this superior gait ability persisted. In conclusion, the therapy on the novel gait robot resulted in a superior gait and stair climbing ability in nonambulatory patients with subacute stroke; a higher training intensity was the most likely explanation. A large randomized controlled trial should follow.

Managing stairs is a challenging activity of daily living (ADL) for older people. This study aims to examine the association between visual impairment and difficulty in managing stairs among older people living alone and those living with others. A population-based cross sectional study was conducted in rural Malaysia from 2007 till 2008. Seven hundred and sixty five older people aged 60 years and over underwent eye examination for visual impairment. Visual acuity criteria were used to define visual impairment. Presenting visual acuity was assessed using a standard metric Snellen Chart of E type. Difficulty in managing stairs was measured according to a question drawn from the Barthel Index which asks "do you need help in climbing stairs". Overall, the prevalence of difficulty in managing stairs among older people in our population was 135 (18.3%, 95% CI 15.7-21.2). After adjusting for important confounders the odds ratio (OR) for visual impairment and difficulty in managing stairs among older people living alone was 5.04 (95% CI 2.27, 10.62). Among older people living with others, the adjusted OR for visual impairment and difficulty in managing stairs was 3.10 (95% CI 1.52, 6.80). In a sample of older people aged 60 years and over, those living alone with visual impairment had greater difficulty in managing stairs than those living with others. Identification of these groups of older people is useful for targeting interventions. Copyright © 2012 Elsevier Inc. All rights reserved.

Hiegemann, Lars; Agarwal, Chiranshu; Weddeling, Christian; Tekkaya, A. Erman

2016-10-01

The layer technology enables fast and flexible additive manufacturing of forming tools. The disadvantages of this system is the formation of stair steps in the range of tool radii. Within this work a new method to smooth this stair steps by ball burnishing is introduced. This includes studies on the general feasibility of the process and the determination of the influence of the rolling parameters. The investigations are carried out experimentally and numerically. Ultimately, the gained knowledge is applied to finish a deep drawing tool which is manufactured by layer technology.

Unintentional injury due to falls is one of the main reasons for hospitalization among children 0-4 years of age. The goal of this study was to assess the psychosocial correlates of parental safety behaviours to prevent falls from a staircase due to the lack of or the lack of adequate use of a stair gate. Data were collected from a cross-sectional survey using self-administered questionnaires mailed to a population sample of 2470 parents with toddlers. Associations between self-reported habits on the presence and use of stair gates and family and psychosocial factors were analysed, using descriptive statistics and multiple regression models, based on Protection Motivation Theory. The presence of stair gates was associated with family situation, perceived vulnerability, response efficacy, social norms and descriptive norms. The use of stair gates was associated with family situation, response efficacy, self-efficacy and perceived advantages of safe behaviour. The full model explained 32 and 24% of the variance in the presence of stair gates and the use of stair gates, respectively, indicating a large and medium effect size. Programmes promoting the presence and adequate use of stair gates should address the family situation, personal cognitive factors as well as social factors.

Compensatory movement strategies may develop in response to pain to avoid stress on the affected area. Patellofemoral pain is characterised by intermittent periods of pain and the present study addresses whether long-term pain leads to compensatory movement strategies that remain even when the pain is absent. Lower extremity kinematics in three dimensions was studied in stair descent in 17 women with patellofemoral and in 17 matched controls. A two-dimensional geometric model was constructed to normalise kinematic data for subjects with varying anthropometrics when negotiating stairs of fixed proportions. There were minor differences in movement patterns between groups. Knee joint angular velocity in the stance leg at foot contact was lower and the movement trajectory tended to be jerkier in the patellofemoral group. The two-dimensional model showed greater plantar flexion in the swing leg in preparation for foot placement in the patellofemoral group. The results indicate that an altered stair descent strategy in the patellofemoral group may remain also in the absence of pain. The biomechanical interpretation presumes that the strategy is aimed to reduce knee joint loading by less knee joint moment and lower impact force.

Boen, Filip; Maurissen, Katrien; Opdenacker, Joke

2010-06-01

The aim of this study was to test the impact of a simple health-promotion sign on stair use in three community settings in Flanders, Belgium. A health sign was placed at the junction between the stairs and an escalator in a shopping mall and two train stations. Observations took place on four days: baseline, first intervention, post-intervention and second intervention. In the second station, a second post-intervention phase was added. In total, 1437 choices of shoppers were registered in the mall, while 2869 and 2025 choices of commuters were recorded in the two stations, respectively. Despite the different baselines of stair use, the introduction of the health sign in the first intervention phase resulted in a significant increase in all three settings: 10.0% increase in the mall, 8.6% in the first station and 18.0% in the second station. In the second station, the increase during the second intervention exceeded that of the first intervention. Moreover, in this station stair use in the second post-intervention phase was significantly higher than at baseline. An inexpensive health-promoting sign has a substantial effect on the proportion of stair users among shoppers and commuters. Preliminary evidence was found that repeated exposure to a health sign might have a longer term effect on stair use.

Autonomous motivation is not enough: the role of compensatory health beliefs for the readiness to change stair and elevator use.

Compensatory health beliefs (CHBs) are beliefs that an unhealthy behavior can be compensated with a healthy behavior. In line with the CHBs model, the aim of this study was twofold. First, the study investigated the relationship between autonomous motivation and CHBs that physical inactivity can be compensated by taking the stairs instead of the elevator. Second, the study focused on the associations between CHBs and readiness to use the stairs more often and stair and elevator use. Thus, a cross-sectional online questionnaire was designed that was filled out by 135 participants. Path analysis showed that individuals with stronger autonomous motivation to use the stairs strongly agreed that sedentary behavior could be compensated by taking the stairs instead of the elevator. Moreover, CHBs were positively related to readiness to change behavior, but not to self-reported stair and elevator use. Even though future research is necessary to replicate these findings, autonomous motivation seems to have a positive impact on CHBs which, in turn, might boost an intended behavior change. Thus, promoting possible compensation of physical inactivity might foster the readiness to change the unhealthy behavior.

Full Text Available Editorial Notes provide a view "behind the scenes" of FQS Reviews, reporting and describing the editorial process. The first topic in this Editorial Note focuses on changes in the way reviewers are found. As FQS Reviews began we preferred finding reviewers by posting on different listservs to inform others about review copies of books and other media. In the next phase of FQS Reviews—aside from postings—we attempted to establish a core of authors who would exclusively write reviews. The second topic describes an analyses of 131 archived files (first drafts of reviews published in FQS and the analyses of the e-mail contacts between the reviewers and the editorial team which accompany the peer review process. One result of our analyses is that the quality of a review is independent from way the reviewer was recruited (postings on listservs or established core reviewer; no significant differences can be seen between the two groups (reviewers found via listservs or established reviewers. More, important, however, is the intensive "communication work" between editors and reviewers—a necessary communication to guarantee standardization and maintenance of quality. This is critical as our focus is on the review as a "unique contribution" within the research community. To give an insight into the intensive communication work an anonymous case study of a "failed" review is included. URN: urn:nbn:de:0114-fqs040115

Full Text Available Abstract Background Accumulation of lifestyle physical activity is a current aim of health promotion, with increased stair climbing one public health target. While the workplace provides an opportunity for regular stair climbing, evidence for effectiveness of point-of-choice interventions is equivocal. This paper reports a new approach to worksite interventions, aimed at changing attitudes and, hence, behaviour. Methods Pre-testing of calorific expenditure messages used structured interviews with members of the public (n = 300. Effects of multi-component campaigns on stair climbing were tested with quasi-experimental, interrupted time-series designs. In one worksite, a main campaign poster outlining the amount of calorific expenditure obtainable from stair climbing and a conventional point-of-choice prompt were used (Poster alone site. In a second worksite, additional messages in the stairwell about calorific expenditure reinforced the main campaign (Poster + Stairwell messages site. The outcome variables were automated observations of stair and lift ascent (28,854 and descent (29,352 at baseline and for three weeks after the intervention was installed. Post-intervention questionnaires for employees at the worksites assessed responses to the campaign (n = 253. Analyses employed Analysis of Variance with follow-up Bonferroni t-tests (message pre-testing, logistic regression of stair ascent and descent (campaign testing, and Bonferroni t-tests and multiple regression (follow-up questionnaire. Results Pre-testing of messages based on calorific expenditure suggested they could motivate stair climbing if believed. The new campaign increased stair climbing, with greater effects at the Poster + Stairwell messages site (OR = 1.52, 95% CI = 1.40-1.66 than Posters alone (OR = 1.24, 95% CI = 1.15-1.34.

Stair climbing up and down is an essential part of everyday's mobility. To enable wheelchair-dependent patients the repetitive practice of this task, a novel gait robot, G-EO-Systems (EO, Lat: I walk), based on the end-effector principle, has been designed. The trajectories of the foot plates are freely programmable enabling not only the practice of simulated floor walking but also stair climbing up and down. The article intended to compare lower limb muscle activation patterns of hemiparetic subjects during real floor walking and stairs climbing up, and during the corresponding simulated conditions on the machine, and secondly to demonstrate gait improvement on single case after training on the machine. The muscle activation pattern of seven lower limb muscles of six hemiparetic patients during free and simulated walking on the floor and stair climbing was measured via dynamic electromyography. A non-ambulatory, sub-acute stroke patient additionally trained on the G-EO-Systems every workday for five weeks. The muscle activation patterns were comparable during the real and simulated conditions, both on the floor and during stair climbing up. Minor differences, concerning the real and simulated floor walking conditions, were a delayed (prolonged) onset (duration) of the thigh muscle activation on the machine across all subjects. Concerning stair climbing conditions, the shank muscle activation was more phasic and timely correct in selected patients on the device. The severely affected subject regained walking and stair climbing ability. The G-EO-Systems is an interesting new option in gait rehabilitation after stroke. The lower limb muscle activation patterns were comparable, a training thus feasible, and the positive case report warrants further clinical studies.

Stair Climbing Control for 4-DOF Tracked Vehicle Based on Internal Sensors

Full Text Available In search-and-rescue missions, multi-degrees-of-freedom (DOF tracked robots that are equipped with subtracks are commonly used. These types of robots have superior locomotion performance on rough terrain. However, in teleoperated missions, the performance of tracked robots depends largely on the operators’ ability to control every subtrack appropriately. Therefore, an autonomous traversal function can significantly help in the teleoperation of such robots. In this paper, we propose a planning and control method for 4-DOF tracked robots climbing up/down known stairs automatically based on internal sensors. Experimental results obtained using mockup stairs verify the effectiveness of the proposed method.

Stair walking is one of the most challenging tasks for older adults, with women reporting higher incidence of falls. The purpose of this study was to investigate the gender differences in kinetics during stair descent transition. Twenty-eight participants (12 male and 16 female; 68.5 and 69.0 years of mean age, respectively) performed stair descent from level walking in a step-over-step manner at a self-selected speed over a custom-made three-step staircase with embedded force plates. Kinematic and force data were combined using inverse dynamics to generate kinetic data for gender comparison. The top and the first step on the staircase were chosen for analysis. Women showed a higher trail leg peak hip abductor moment (-1.0 Nm/kg), lower trail leg peak knee extensor moment and eccentric power (0.74 Nm/kg and 3.15 W/kg), and lower peak concentric power at trail leg ankle joint (1.29 W/kg) as compared to men (ppredispose women to a higher risk of fall.

To determine whether single-leg squats identify ability to negotiate stairs in older adults at a rural hospital. Cross-sectional analytical study. Acute wards and emergency department of a rural hospital in Australia. A systematic sample of 143 older adults (72 men, 71 women, 80.0 ± 6.8 years) from the emergency department or acute wards of Shoalhaven Hospital referred for a physiotherapy mobility assessment. Ability to complete up to three single-leg squats and negotiate up to three steps were measured. Covariates and demographic variables were collected. The squat test had 86% sensitivity, 100% specificity, 100% positive predictive value, and 49% negative predictive value in correctly identifying stair negotiation ability. Participants who could complete single-leg squats were 57 times more likely to be able to independently negotiate stairs than participants who could not complete squats. Multivariate regression analysis indicated that walker use, pain severity and whether participants lived alone were significant and independent predictors of ability to negotiate stairs independently. Single-leg squats may be an accurate identifier of stair negotiation ability in older adults admitted to the hospital for an acute illness or injury. A traditional stairs assessment would be required if older adults were unable to complete the squat test or had moderate to severe pain, used a walker to ambulate, or did not live alone. The squat test is a potentially more-efficient assessment tool than traditional stair assessments in determining an individual's ability to negotiate stairs and suitability for discharge where poor mobility is a problem. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

To enable wheelchair-dependent patients the repetitive practice of this task, a novel gait robot, G-EO-Systems (EO, Lat: I walk, based on the end-effector principle, has been designed. The trajectories of the foot plates are freely programmable enabling not only the practice of simulated floor walking but also stair climbing up and down. The article intended to compare lower limb muscle activation patterns of hemiparetic subjects during real floor walking and stairs climbing up, and during the corresponding simulated conditions on the machine, and secondly to demonstrate gait improvement on single case after training on the machine. Methods The muscle activation pattern of seven lower limb muscles of six hemiparetic patients during free and simulated walking on the floor and stair climbing was measured via dynamic electromyography. A non-ambulatory, sub-acute stroke patient additionally trained on the G-EO-Systems every workday for five weeks. Results The muscle activation patterns were comparable during the real and simulated conditions, both on the floor and during stair climbing up. Minor differences, concerning the real and simulated floor walking conditions, were a delayed (prolonged onset (duration of the thigh muscle activation on the machine across all subjects. Concerning stair climbing conditions, the shank muscle activation was more phasic and timely correct in selected patients on the device. The severely affected subject regained walking and stair climbing ability. Conclusions The G-EO-Systems is an interesting new option in gait rehabilitation after stroke. The lower limb muscle activation patterns were comparable, a training thus feasible, and the positive case report warrants further clinical studies.

Population strategies to increase physical activity are an essential part of cardiovascular disease prevention. However, little data exist on lifestyle interventions that are easy to integrate into everyday life such as using stairs instead of elevators at the workplace. Pre and postintervention study. A 12-week promotional campaign for stair use consisting in posters and floor stickers at the point of choice between stairs and elevators at each hospital floor was organized in a university hospital building. In 77 selected employees with an inactive lifestyle, physical activity, aerobic fitness, anthropometrics, blood pressure, lipids, insulin sensitivity, and C-reactive protein were assessed at baseline, 12 weeks, and 6 months. During the intervention median daily number of ascended and descended one-story staircase units was 20.6/day (14.2-28.1) compared with 4.5/day (1.8-7.2) at baseline (P<0.001). At 12 weeks, estimated maximal aerobic capacity had increased by 9.2±15.1% (P<0.001) corresponding with approximately 1 MET. There were significant declines in waist circumference (-1.7±2.9%), weight (-0.7±2.6%), fat mass (-1.5±8.4%), diastolic blood pressure (-1.8±8.9%), and low-density lipoprotein cholesterol (-3.0±13.5%). At 6 months, the median daily number of ascended and descended one-story staircase units had decreased to 7.2 (3.5-14.0). Benefits on estimated maximal aerobic capacity (+5.9±12.2%, P=0.001) and fat mass (-1.4±8.4%, P=0.038) persisted. Encouraging stair use at work is effective for improving fitness, body composition, blood pressure, and lipid profile in asymptomatic individuals with an inactive lifestyle and thus may be a simple way to significantly reduce cardiovascular disease risk at the population level.

Before making interpretations on the effects of interventions or on the features of pathological gait patterns during stair ambulation, the day-to-day consistency of the investigated variables must be established. In this article, the day-to-day consistency was determined for kinematic variables during barefoot stair ambulation. Ten healthy athletes performed two gait analysis sessions, at least one week apart, utilizing a marker set of 47 skin markers, and a functional joint center/axes determination. Being found on limits of agreement and mean differences between the repeated stair ambulation sessions, totally 43 ranges of motions were examined at the hip, knee, ankle, and midfoot joints. The day-to-day consistency was generally in the magnitude of three degrees, irrespective of test condition, investigated joint, or regarded cardinal body plane. The reported values of the day-to-day consistency provide guidelines to distinguish between pathological and healthy gait patterns, and thresholds to determine minimal effects of interventions during stair ambulation.

In developing software for independent verification and validation (IVV) of the Image Navigation and Registration (INR) capability for the Geostationary Operational Environmental Satellite R Series (GOES-R) Advanced Baseline Imager (ABI), we have encountered an image registration artifact which limits the accuracy of image offset estimation at the subpixel scale using image correlation. Where the two images to be registered have the same pixel size, subpixel image registration preferentially selects registration values where the image pixel boundaries are close to lined up. Because of the shape of a curve plotting input displacement to estimated offset, we call this a stair-step artifact. When one image is at a higher resolution than the other, the stair-step artifact is minimized by correlating at the higher resolution. For validating ABI image navigation, GOES-R images are correlated with Landsat-based ground truth maps. To create the ground truth map, the Landsat image is first transformed to the perspective seen from the GOES-R satellite, and then is scaled to an appropriate pixel size. Minimizing processing time motivates choosing the map pixels to be the same size as the GOES-R pixels. At this pixel size image processing of the shift estimate is efficient, but the stair-step artifact is present. If the map pixel is very small, stair-step is not a problem, but image correlation is computation-intensive. This paper describes simulation-based selection of the scale for truth maps for registering GOES-R ABI images.

Autonomous Motivation Is Not Enough: The Role of Compensatory Health Beliefs for the Readiness to Change Stair and Elevator Use

OpenAIRE

Radtke, Theda; Rackow, Pamela

2014-01-01

Compensatory health beliefs (CHBs) are beliefs that an unhealthy behavior can be compensated with a healthy behavior. In line with the CHBs model, the aim of this study was twofold. First, the study investigated the relationship between autonomous motivation and CHBs that physical inactivity can be compensated by taking the stairs instead of the elevator. Second, the study focused on the associations between CHBs and readiness to use the stairs more often and stair and elevator use. Thus, a c...

Unicompartmental knee arthroplasty (UKA) has been shown to demonstrate some satisfactory short-term outcomes. However, to our knowledge, there have been no reports on midterm or long-term knee extensor strength and leg extensor power post-UKA. Therefore, the purposes of this study were: (1) to assess the isokinetic knee extensor strength, leg extensor power and stair performance of elderly participants at 5 years UKA post-operation; (2) to compare the differences in knee extensor strength and leg extensor power between the UKA and contralateral healthy limbs. Nineteen elderly participants (75 ± 5 years) who had a medial or a lateral compartment UKA at 5 years post-operation were recruited. The isokinetic knee extensor strength and leg extensor power were measured. The stair performance was tested on a 4-step stair, and ascent and descent velocities were calculated. The pain level was assessed. The UKA limbs' knee extensor strength and leg extensor power were 1.01 ± 0.39 Nm/kg and 0.98 ± 0.27 W/kg, respectively. The stair ascent and descent velocities were 0.37 ± 0.07 and 0.38 ± 0.11 m/s, respectively. In addition, the UKA limbs exhibited comparable knee strength and leg power relative to the contralateral limbs. In general, the knee extensor strength and leg extensor power exhibited by the UKA limbs at 5 years post-operation may be typical in comparison with the normative data. We suggest that UKA is a satisfactory treatment in regard to the recovery of knee strength, leg power and ability to climb up and down stairs.

This issue of EPJ D introduces a revised list of sections and subsections, designed in close collaboration with the whole editorial board. The aim of these modifications is to reflect more faithfully the wide diversity of activities covered by our journal. A new section is introduced. Entitled “Atomic and Molecular Collisions”, it covers a large range of activities, from atom/atom or atom/molecules collisions (including the very active field of ultra-cold collisions in laser-cooled atomic or molecular gases), to electron scattering and molecular reactivity. The creation of this section reflects the increased interest of the journal for molecular and collisional physics, already apparent in the recent extension of the editorial board competence in this direction. We very much hope that this community will react positively to this trend and become a major component of the journal's life. For the other sections, we have markedly revised the list of subheadings. We think it important to make it as detailed as possible, both to indicate that EPJ D aims at being a generalist journal for AMO physics and to help our authors to find easily the proper section for their submissions. There is of course no way to describe the whole field's activity in a few subheadings. They are all to be understood with the broadest meaning. This list is by no means an exclusive one. All theoretical or experimental papers connected to atomic, molecular, plasma, quantum or optical physics are welcome. This revised section list appears almost simultaneously with the new WEB portal to all EPJ journals (www.eurphysj.org), which will be online within a few weeks. It unites the material formerly presented on our publisher's WEB sites (EDP Sciences, SIF and Springer). All the journal contents are available there (and all WEB registrations are of course valid for this portal). We offer also a free access to the highlight papers (see our editorial, Eur. Phys. J.

Full Text Available We’ve reached the end of another year of publication at EBLIP, my first at the helm as Editor‐in‐Chief, and four full years of publication since we began. This year was a busy one with several changes to the editorial team, the addition of more Editorial Advisors, and new evidence summary writers joining our team. Most importantly, the journal continues to grow and thrive, with more people than ever participating in its success. This year we added a new section called Using Evidence in Practice, and in this issue there are two articles in that section which provide practical examples of applying evidence in the workplace. Putting evidence into practice is what EBLIP is all about, so it is my hope that this new section makes the application of evidence based practice more concrete for readers. As we began working on issue 4.4, the Editorial Team decided that it would be a good idea to seek out an Editorial Intern to help with some of the tasks we never seem to get to, given that we are all volunteers. We see the internship as an opportunity to give a library and information studies student a chance to get involved with an open access journal and learn about publishing in library and information studies, which will hopefully benefit them as they begin their new career. The Editorial Intern will assist with marketing and promotion of the journal, soliciting potential manuscripts, and proofreading. They will also participate in all editorial meetings and general discussions. We anticipate that they will bring a wealth of enthusiasm and fresh ideas to our conversations so that EBLIP Editors can also continue to learn and grow by having a fresh set of eyes involved with our processes. It will certainly be a win‐win situation and a learning opportunity for all involved. We are pleased to announce that Andrea Baer has accepted the position of Editorial Intern and joined our team in mid‐November. Andrea is currently attending the University of

As the successor to Professor Teruo Kishi, the former Editor-in-Chief of Science and Technology of Advanced Materials (STAM), I would like to share some of STAM's journal history with our readers. STAM was launched in 2000 with the financial support of the Japanese Ministry of Education, Culture, Sports, Science and Technology in recognition of a strong need for an international journal that would be distributed and read across the globe. Five years later, the publication of STAM was transferred to the National Institute for Materials Science (NIMS) under the initiative of Professor Kishi. As a result of his work, STAM is now positioned as a high-impact journal, 3.512 as listed by the ISI 2011 Science Citation Index Journal Citation Report, with a much higher and faster growth than when I was participating as a co-founder in the past. STAM is well known as a successful open-access journal since shifting from the initial subscription model in 2008. As an editor, I would like to emphasize that STAM will continue to publish with a sense of social mission as an academic journal, allowing space for researchers to contribute to the sustainable development of society and health. However, some contribution from authors would assist us in creating a sustainable journal publishing model, and further enhance services to authors and readers of STAM. With this in mind, I would like to state that STAM's editorial board is planning to introduce an article processing charge from July 2013, in addition to NIMS' continuing financial support. One of our new editorial policies is to aim for reader-oriented publishing. I believe that academic journal publishing can take the role of navigator in advancing the development of materials. Among the many other scientific journals, STAM will lead the rapid growth in materials science, inspiring research into new materials for the future and leading the next generation of materials science and technology.

This study was a randomized crossover of stair ambulation of Transfemoral Amputees (TFAs) using the Genium and C-Leg prosthetic knees. TFAs typically have difficulty ascending and descending stairs, limiting community mobility. The objective of this study was to determine the relative efficacy of the Genium and C-Leg prostheses for stair ascent and descent, and their absolute efficacy relative to non-amputees. Twenty TFAs, and five non-amputees participated in the study. TFAs were randomized to begin the study with the Genium or C-Leg prosthesis. Informed consent was obtained from all participants prior to data collection and the study was listed on clinicaltrials.gov (#NCT01473662). After fitting, accommodation, and training, participants were asked to demonstrate their preferred gait pattern for stair ascent and descent and a step-over-step pattern if able. TFAs then switched prosthetic legs and repeated fitting, accommodation, training, and testing. An eight camera Vicon optical motion analysis system, and two AMTI force plates were used to track and analyze the participants' gait patterns, knee flexion angles, knee moment normalized by body weight, and swing time. For stair descent, no significant differences were found between prostheses. For stair ascent, Genium use resulted in: increased ability to use a step-over-step gait pattern (p=0.03), increased prosthetic side peak knee flexion (pstair ascent relative to the C-Leg, by enabling gait patterns that more closely resembled non-amputees.

Adults 70 years and older (N=513; mean age, 80.8 ± 5.1y) without disability or dementia. Not applicable. Time to ascend and descend 3 steps measured at baseline. A 14-point disability scale assessed functional status at baseline and at follow-up interviews every 2 to 3 months. Functional decline was defined as an increase in the disability score by 1 point during the follow-up period. The mean±SD stair ascent and descent times for 3 steps were 2.78 ± 1.49 and 2.83 ± 1.61 seconds, respectively. The proportion of self-reported and objective difficulty was higher with longer stair ascent and descent times (PRehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Effects of exercise on foot clearances are important. In older adults variations in foot clearances during walking may lead to a fall, but there is a lack of information concerning stair negotiation in older adults. Whether a condition of post exercise changes foot clearances between steps of a staircase in older adults still unknown. To determine differences in clearances when older adults negotiate different steps of a staircase before and after a session of aerobic exercise. Kinematics data from 30 older adults were acquired and the toe and heel clearances were determined for each step. Clearances were compared between the steps. Smaller clearances were found at the highest step during ascending and descending, which was not changed by exercise. Smaller clearances suggest higher risk of tripping at the top of the staircase, regardless of exercise. A smaller step at the top of a short flight of stairs could reduce chances of tripping in older adults. It suggests that steps with variable height could make stair negotiation safer in older adults. This hypothesis should be tested in further studies.

The knowledge of normal patellar tracking is essential for understanding of the knee joint function and for diagnosis of patellar instabilities. This paper investigated the patellar tracking and patellofemoral joint contact locations during a stair ascending activity using a validated dual-fluoroscopic imaging system. The results showed that the patellar flexion angle decreased from 41.9° to 7.5° with the knee extension during stair ascending. During first 80% of the activity, the patella shifted medially about 3.9 mm and then slightly shifted laterally during the last 20% of the ascending activity. Anterior translation of 13 mm of the patella was measured at the early 80% of the activity and then slightly moved posteriorly by about 2 mm at the last 20% of the activity. The path of the cartilage contact points was slightly lateral on the cartilage surfaces of patella and femur. On the patellar cartilage surface, the cartilage contact locations were about 2 mm laterally from heel strike to 60% of the stair ascending activity and moved laterally and reached 5.3 mm at full extension. However, the cartilage contact locations were relatively constant on the femoral cartilage surface (~5 mm lateral). The patellar tracking pattern was consistent with the patellofemoral cartilage contact location pattern. These data could provide baseline knowledge for understanding of normal physiology of the patellofemoral joint and can be used as a reference for clinical evaluation of patellofemoral disorder symptoms.

Gaillardin, Florence; Baudry, Stéphane

2018-06-01

This study assessed the influence of attention division, working memory and executive function on stair ascent and descent in young and older adults. Twenty young (25.5 ± 2.1 yrs) and 20 older adults (68.4 ± 5.4 yrs) ascended and descended a 3-step staircase with no simultaneous cognitive task (single-motor task) or while performing a cognitive task (dual-task condition). The cognitive task involved either 1) recalling a word list of the subject's word-span minus 2 words (SPAN-2) to assess the attention division effect, 2) a word list of subject's word-span (SPAN-O) to assess the working memory effect, or 3) recalling in alphabetical order, a word list of the subject's word-span (SPAN-A) to assess the executive function effect. Word-span corresponds to the longest string of words that can be recalled correctly. The duration of ascent and descent of stairs was used to assess the cognitive-motor interaction. Stair ascent and descent duration did not differ between age groups for the single-motor task, and was similar between single-motor task and SPAN-2 in both groups (p > 0.05). In contrast, stair ascent and descent duration increased with SPAN-O compared with SPAN-2 for both groups (p SPAN-A than SPAN-O only in older adults. Healthy aging was not associated with a decrease in the capacity to perform motor-cognitive dual tasks that involved ascending and descending of stairs when the cognitive task only required working memory. However, the decrease in dual-task performance involving executive functioning may reflect a subclinical cognitive decline in healthy older adults. Copyright © 2018 Elsevier Inc.

In lab-on-a-chip systems, various microfluidic technologies are being developed to handle fluids at very small quantities, e.g. in the scale of nano- or pico-liter. To achieve autonomous fluid handling at a low cost, passive fluidic control, based on the capillary force between the liquid and microchannel surface, is of the utmost interest in the microsystem. Valves are an essential component for flow control in many microfluidic systems, which enables a sequence of fluidic operations to be performed. In this paper, we present a new passive valve structure for a capillary driven microfluidic device. It is a variation of a capillary trigger valve that is amenable to silicon microfabrication; it will be referred to as a stair-step liquid triggered valve. In this paper, the valve functionality and its dependencies on channel geometry, surface contact angle, and surface roughness are studied both experimentally and with numerical modeling. The effect of the contact angle was explored in experiments on the silicon microfabricated valve structure; a maximal working contact angle, above which the valve fails to be triggered, was demonstrated. The fluidic behavior in the stair-step channel structure was further explored computationally using the finite volume method with the volume-of-fluid approach. Surface roughness due to scalloping of the sidewall during the Bosch etch process was hypothesized to reduce the sidewall contact angle. The reduced contact angle has considerable impacts on the capillary pressure as the liquid vapor interface traverses the stair-step structure of the valve. An improved match in the maximal working contact angle between the experiments and model was obtained when considering this surface roughness effect.

Previous studies indicate that flexible footwear, which mimics the biomechanics of walking barefoot, results in decreased knee loads in patients with knee osteoarthritis (OA) during walking. However, the effect of flexible footwear on other activities of daily living, such as descending stairs, remains unclear. Our objective was to evaluate the influence of inexpensive and minimalist footwear (Moleca) on knee adduction moment (KAM) during stair descent of elderly women with and without knee OA. Thirty-four elderly women were equally divided into an OA group and a control group (CG). Stair descent was evaluated in barefoot condition, while wearing the Moleca, and while wearing heeled shoes. Kinematics and ground reaction forces were measured to calculate KAM by using inverse dynamics. The OA group experienced a higher KAM during midstance under the barefoot condition (233.3%; P = 0.028), the Moleca (379.2%; P = 0.004), and heeled shoes (217.6%; P = 0.007). The OA group had a similar knee load during early, mid, and late stance with the Moleca compared with the barefoot condition. Heeled shoes increased the knee loads during the early-stance (versus barefoot [16.7%; P stair descent. The loads are similar to the barefoot condition and effectively decreased when compared with heeled shoes. Copyright © 2012 by the American College of Rheumatology.

It is commonly believed that a torn ACL or a damaged meniscus may be associated with altered knee joint movements. The purpose of this study was to measure the tibiofemoral kinematics of ACL deficiency with concomitant meniscus deficiency. Unilateral knees of 28 ACL deficient participants were studied while ascending stairs. Among these patients, 6 had isolated ACL injuries (group I), 8 had combined ACL and medial meniscus injuries (group II), 8 had combined ACL and lateral meniscus injuries (group III) and 6 had combined ACL and medial-lateral meniscus injuries (group IV). Both knees were then scanned during a stair climb activity using single fluoroscopic image system. Knee kinematics were measured at 0°, 5°, 10°, 15°, 30° and 60° of flexion during ascending stairs. At 0°, 15° and 30° flexion of the knee, the tibia rotated externally by 13.9 ± 6.1°,13.8 ± 9.5° and 15.9 ± 9.8° in Group I. Group II and III exhibited decreased external rotation from 60° to full extension. Statistical differences were found in 0°, 15°and 30° of flexion for the 2 groups compared with Group I. In general, the tibia showed anterior translation with respect to the femur during ascending stairs. It was further determined that Group III had larger anterior translation compared with Group IV at 0° and 5° of flexion (-6.9 ± 1.7 mm vs. 6.2 ± 11.3 mm, P = 0.041; -9.0 ± 1.8 mm vs. 8.1 ± 13.4 mm, P = 0.044). During ascending stairs the ACL deficient knee with different deficiencies in the meniscus will show significantly different kinematics compared with that of uninjured contralateral knee. Considering the varying effect of meniscus injuries on knee joint kinematics, future studies should concentrate on specific treatment of patients with combined ACL and meniscus injuries to protect the joint from abnormal kinematics and subsequent postoperative degeneration.

Patterns in the knee flexion-extension moment profile during stair ascent and descent in patients with total knee arthroplasty.

Science.gov (United States)

McClelland, Jodie A; Feller, Julian A; Menz, Hylton B; Webster, Kate E

2014-06-03

The aim of this study was to investigate the prevalence of abnormal knee biomechanical patterns in 40 patients with a modern TKA prosthesis, compared to 40 matched control participants when ascending and descending stairs. Fewer patients were able to ascend (65%) or descend stairs (53%) unassisted than controls (83%). Of the participants who could ascend and descend, cluster analysis classified most patients (up to 77%) as demonstrating a similar knee moment pattern as all controls. A small subgroup of patients who completed the tasks did so with distinctly abnormal biomechanics compared to other patients and controls. These findings suggest that recovery of normal stair climbing is possible. However, rehabilitation might be more effective if it were tailored to account for these differences between patients.

The stair-step approach in mathematics

CERN Document Server

Sedrakyan, Hayk

2018-01-01

This book is intended as a teacher’s manual and as an independent-study handbook for students and mathematical competitors. Based on a traditional teaching philosophy and a non-traditional writing approach (the stair-step method), this book consists of new problems with solutions created by the authors. The main idea of this approach is to start from relatively easy problems and “step-by-step” increase the level of difficulty toward effectively maximizing students' learning potential. In addition to providing solutions, a separate table of answers is also given at the end of the book. A broad view of mathematics is covered, well beyond the typical elementary level, by providing more in depth treatment of Geometry and Trigonometry, Number Theory, Algebra, Calculus, and Combinatorics.

Stair walking is more energizing than low dose caffeine in sleep deprived young women.

Science.gov (United States)

Randolph, Derek D; O'Connor, Patrick J

2017-05-15

The acute energizing effect of exercise and caffeine has never been examined in a single study of adults with chronic sleep deprivation but evidence from a study of this type could help individuals choose between these two common alertness-enhancing options. The apriori primary aim of this experiment was to compare the influence of 10-min of low-to-moderate intensity stair walking to the consumption of capsules containing 50mg caffeine or flour (placebo) on feelings of energy in physically active, college female caffeine users with chronic insufficient sleep. Effects on secondary outcomes related to feelings of energy also were assessed. A repeated measures crossover experiment was conducted with 18 college women (18-23years) who reported (i) daily caffeine consumption that was not extreme (40-400mg), (ii) typical leisure time physical activity that was not extreme (at least 2 weekly mild 15-min or longer bouts and no >5 strenuous 15-min or longer bouts), and (iii) sleeping memory (N-back), sustained attention (CPT), simple reaction time (SRT), and motivation to complete the cognitive tasks were measured before and after a 10-min exercise condition (20min seated rest followed by 10min of low-to-moderate intensity stair walking) and compared to both a caffeine condition (50mg caffeine capsule followed by 30min of seated rest) and a similar flour (placebo) capsule condition. Condition (exercise, caffeine, placebo)×Time (Baseline, Post-1, Post-2, and for mood Post-3) ANCOVAs (controlling for Condition order) tested the hypothesized effects. Condition×Time interactions showed that stair walking increased POMS-BF vigor at Post-1 compared to both placebo and caffeine. Other interactions were not significant. A brief bout of low-to-moderate intensity stair walking has transient energizing effects that exceed a low dose of caffeine for active young women with chronic insufficient sleep.

Goo, Young-Mi; Kim, Da-Yeon; Kim, Tae-Ho

2016-03-01

[Purpose] The purpose of the present study was to examine the effects of toe-spread (TS) exercises and hip external rotator strengthening exercises for pronated feet on lower extremity muscle activities during stair-walking. [Subjects and Methods] The participants were 20 healthy adults with no present or previous pain, no past history of surgery on the foot or the ankle, and no foot deformities. Ten subjects performed hip external rotator strengthening exercises and TS exercises and the remaining ten subjects performed only TS exercises five times per week for four weeks. [Results] Less change in navicular drop height occurred in the group that performed hip external rotator exercises than in the group that performed only TS exercises. The group that performed only TS exercises showed increased abductor hallucis muscle activity during both stair-climbing and -descending, and the group that performed hip external rotator exercises showed increased muscle activities of the vastus medialis and abductor hallucis during stair-climbing and increased muscle activity of only the abductor hallucis during stair-descending after exercise. [Conclusion] Stair-walking can be more effectively performed if the hip external rotator muscle is strengthened when TS exercises are performed for the pronated foot.

Increased physical activity can provide numerous health benefits. The relationship between physical activity and health assumes reliable activity measurements including step count and distance traveled. This study assessed step count and distance accuracy for Nike+ FuelBand, Jawbone UP 24, Fitbit One, Fitbit Flex, Fitbit Zip, Garmin Vivofit, Yamax CW-701, and Omron HJ-321 during level, upstairs, and downstairs walking in healthy adults. Forty subjects walked on flat ground (400m), upstairs (176 steps), and downstairs (176 steps), and a subset of 10 subjects performed treadmill walking trials to assess the influence of walking speed on accuracy. Activity monitor measured step count and distance values were compared with actual step count (determined from video recordings) and distance to determine accuracy. For level walking, step count errors in Yamax CW-701, Fitbit Zip, Fitbit One, Omron HJ-321, and Jawbone UP 24 were within 1% and distance errors in Fitbit Zip and Yamax CW-701 were within 5%. Garmin Vivofit and Omron HJ-321 were the most accurate in estimating step count for stairs with errors less than 4%. An important finding is that all activity monitors overestimated distance for stair walking by at least 45%. In general, there were not accuracy differences among activity monitors for stair walking. Accuracy did not change between moderate and fast walking speeds, though slow walking increased errors for some activity monitors. Nike+ FuelBand was the least accurate step count estimator during all walking tasks. Caution should be taken when interpreting step count and distance estimates for activities involving stairs.

2015-06-01

Angular momentum of the body is a highly controlled quantity signifying stability, therefore, it is essential to understand its regulation during stair descent. The purpose of this study was to investigate how older adults use gravity and ground reaction force to regulate the angular momentum of the body during stair descent. A total of 28 participants (12 male and 16 female; 68.5 years and 69.0 years of mean age respectively) performed stair descent from a level walk in a step-over-step manner at a self-selected speed over a custom made three-step staircase with embedded force plates. Kinematic and force data were used to calculate angular momentum, gravitational moment, and ground reaction force moment about the stance foot center of pressure. Women show a significantly greater change in normalized angular momentum (0.92Nms/Kgm; p=.004) as compared to men (0.45Nms/Kgm). Women produce higher normalized GRF (p=.031) during the double support phase. The angular momentum changes show largest backward regulation for Step 0 and forward regulation for Step 2. This greater difference in overall change in the angular momentum in women may explain their increased risk of fall over the stairs. Copyright © 2015 Elsevier B.V. All rights reserved.

Kinematic alterations of the lower limbs and pelvis during an ascending stairs task are associated with the degree of knee osteoarthritis severity.

Science.gov (United States)

Gonçalves, Glaucia Helena; Selistre, Luiz Fernando Approbato; Petrella, Marina; Mattiello, Stela Márcia

2017-03-01

Individuals with knee osteoarthritis (OA) generally demonstrate great difficulty in ascending stairs. The strategies and compensations used by these individuals in stair activities have not been fully established. The purpose of this study was to investigate the joint kinematics of the pelvis, hip, knee and ankle throughout the gait cycle, in the sagittal and frontal planes, in individuals with mild and moderate knee OA, during an ascending stairs task. Thirty-one individuals with knee OA and 19 controls were subjected to clinical and radiographic analysis, divided into three groups: control, mild knee OA, and moderate knee OA. Participants answered a self-reported questionnaire, carried out performance-based tests, and their kinematic data were recorded during an ascending stairs task using an eight-camera Qualisys 3D-Motion analysis system. The individuals with moderate degrees of knee OA demonstrated kinematic alterations in the pelvis, hip, knee, and ankle in the sagittal plane. The individuals with mild degrees of knee OA demonstrated kinematic alterations of the hip in the frontal plane, and kinematic alterations of the ankle in the sagittal plane. The ascending stairs task allowed verification of meaningful information regarding gait strategies used by individuals with mild and moderate knee OA. The strategies of these two groups of individuals are different for this task, although more pronounced in individuals with moderate knee OA. The findings should be taken into account in the development of rehabilitation programs. Copyright © 2017 Elsevier B.V. All rights reserved.

Effects of stair-climbing on balance, gait, strength, resting heart rate, and submaximal endurance in healthy seniors.

Science.gov (United States)

Donath, L; Faude, O; Roth, R; Zahner, L

2014-04-01

Stair-climbing serves as a feasible opportunity to remain physically active within everyday-life. Data on neuromuscular and cardiorespiratory performance after regular stair-climbing in seniors are scarce. Forty-eight seniors were stratified to a one- (taking every step, INT1) or two-step strategy (every second step, INT2) or a control group (CON). Thirty-nine seniors [females: n = 22, males: n = 17; age: 70.5 (SD 5.1) years; BMI: 25.8 (3.1) kg/m(2)] completed the 8-week intervention (three weekly sessions). Before and after the intervention, balance, gait, strength, and submaximal endurance (at different intensities) were assessed. Maximal strength and explosive power did not improve significantly (0.10 walking significantly decreased (-11/min; P beam balancing (4.5 cm width) increased in INT2 (P = 0.007) compared with CON. With more pronounced effects in INT2, stair-climbing significantly improved resting and exercise heart rates, perceived exertion, and dynamic balance performance in healthy seniors and may contribute to better overall fitness, reduced fall risk, and less perceived strain during daily life activities. © 2013 John Wiley & Sons A/S.

Taking the stairs instead: The impact of workplace design standards on health promotion strategies

2013-01-01

Full Text Available AbstractBackground Comprehensive health promotion in Western Australia has been conducted from the point of views of policy development, promotion, education and service delivery. Much of this recent work has been focused on supporting workplaces – but there has yet to be any real focus on the design of the actual physical workplace environment from a health promotion perspective. Aims This paper is aimed at highlighting the gap in health promotion knowledge by addressing how the disciplines of architecture and health promotion can work together to challenge the regulations that dictate design practice and ultimately bridge that gap for long-term change. The overarching aim is to undertake further evidenced-based research that will inform best practice in the planning and design of workplaces to reduce sedentary behaviour and increase opportunities for physical activity. Method Within this wide objective this paper focuses in particular on the idea of stairs-versus-lift movement strategies within office buildings. By examining building design guidelines from a health promotion perspective we expose a central dichotomy, where health promotion posters say “Take the stairs instead” whereas the language of building design suggests that the lift is best. Results From a design point of view, the National Codes of Construction (NCC, formally known as the Building Codes of Australia (BCA, the essential technical regulation for all building design and construction, primarily addresses the concepts of ‘egress’ and ‘travel distance’ for escape in the event of fire, and building access in terms of universal access. Additionally, The Property Council of Australia’s Guide to Office Building Quality prioritises lift performance criteria along with the quality and experience of lift use as a major grading factor. There is no provision in either set of standards for staircase quality and experience. Conclusion The stairs, despite being promoted

Huang, Chun-Jung; Garten, Ryan S; Wade, Chip; Webb, Heather E; Acevedo, Edmund O

2009-09-01

No studies have considered whether a firefighter's boots are a factor influencing physiological responses. The purpose of this study was to examine physiological responses to a fire simulation activity (stair climb) in professional firefighters wearing rubber boots (RB) and leather boots (LB). Twelve professional firefighters participated in two counterbalanced simulated firefighter stair climb (SFSC) sessions, one wearing RB and the other wearing LB. Heart rate, oxygen uptake (VO(2)), expiratory ventilation (V(E)), blood lactate (BLa), salivary cortisol (SCORT), and leg strength were assessed prior to and following a SFSC. LB elicited significantly greater SCORT values and knee flexion time to peak torque. Furthermore, RB revealed significantly greater ankle dorsiflexion peak torque after SFSC. BLa was positively related to knee flexion peak torque after SFSC in the RB. Firefighters when wearing the RB may be more effective at resisting fatigue and increase more force production.

We analyze data from a survey of online news consumers focusing on experiences and attitudes towards...... editorial control set against a spectrum between “interventionist” and “noninterventionist” positions. Results indicate that interventionist respondents rate the quality of online comments as poor, whereas noninterventionist respondents have most often experienced being the target of editorial control...... measures and feel that editorial control has intensified after the terror attacks. We conclude that newspapers should pay attention to the different needs of participants when devising strategies for editorial control.

Full Text Available The Center of Forestry Research- CEPEF- is linked to the Fundação de Apoio à Tecnologia e Ciência (FATEC, of the Universidade Federal de Santa Maria, and was created in 1986 with the mission of promoting the scientific investigation, contributing to the solution of the unique problems of the forestry enterprise. For the publication of the technical-scientific knowledge generated in the Institution, and by other researchers in forestry, the Revista Ciência Florestal was created, in 1991, as a result of the combined effort between the University and the private forest sector. The difficulties found in the early number were slowly overcome, with the effective participation of all segments, always looking of the improvement of the scientific and editorial quality, compartible with the qualitative growth goals of the journal. In this context, the incorporation of nationally renown researchers to the editorial board turned the scientific consulting more selective. The first important recognition of this journal happened with its indexing by the CAB International System, from England, in 1997. The repercussion of the inclusion on the indexing system was felt by the significant increase in the number of manuscripts received. To meet this new challenge, and the demand by the Braxilian scientific community, the Editorial Board decided to implement a second number of the journal, making it biannual this year. Thus, the edition of the ninth volume will comprise this first number, in the month of June, and a second one, planned forDecember 1999. Another change, to catch your eyes, is the cover of the Journal, bringing a new style. The design was developed by the Visual Programming Laboratory, of the Center for the Arts and Literature od the UFSM, substantially changing its layout, and giving it a more modern and actual appeal. The innovation will be complemented by a different picture in each volume. CEPEF hopes to modernize its Journal of scientific

Ji, Peng; Song, Aiguo; Song, Zimo; Liu, Yuqing; Jiang, Guohua; Zhao, Guopu

2017-02-01

In this paper, we describe a heading direction correction algorithm for a tracked mobile robot. To save hardware resources as far as possible, the mobile robot’s wrist camera is used as the only sensor, which is rotated to face stairs. An ensemble heading deviation detector is proposed to help the mobile robot correct its heading direction. To improve the generalization ability, a multi-scale Gabor filter is used to process the input image previously. Final deviation result is acquired by applying the majority vote strategy on all the classifiers’ results. The experimental results show that our detector is able to enable the mobile robot to correct its heading direction adaptively while it is climbing the stairs.

[How to make your own custom cutting guides for both mandibular and fibular stair step osteotomies?

2017-12-01

Using tailored cutting guides for osteocutaneous free fibula flap in complex mandibular reconstruction after cancer resection surgery constitutes a substantial improvement. Autonomously conceiving and manufacturing the cutting guides within a plastic surgery department with computer-aided design (CAD) and three-dimensional (3D) printing allows planning more complex osteotomies, such as stair-step osteotomies, in order to achieve more stable internal fixations. For the past three years, we have been producing by ourselves patient-tailored cutting guides using CAD and 3D printing. Osteotomies were virtually planned, making the cutting lines more complex in order to optimize the internal fixation stability. We also printed reconstructed mandible templates and shaped the reconstruction plates on them. We recorded data including manufacturing techniques and surgical outcomes. Eleven consecutive patients were operated on for an oral cavity cancer. For each patient, we planned the fibular and mandibular stair-step osteotomies and we produced tailored cutting guides. In all patients, we achieved to get immediately stable internal fixations and in 10 patients, a complete bone consolidation after 6 months. Autonomously manufacturing surgical cutting guides for mandibular reconstruction by free fibula flap is a significant improvement, regarding ergonomics and precision. Planning stair-step osteotomies to perform complementary internal fixation increases contact surface and congruence between the bone segments, thus improving the reconstructed mandible stability.

In this study, we propose a simple hopping mechanism using the vibration of a two-degree-of-freedom system for a wheel-based stair-climbing robot. The robot, consisting of two bodies connected by springs and a wire, hops by releasing energy stored in the springs and quickly travels using wheels mounted in its lower body. The trajectories of the bodies during hopping change in accordance with the design parameters, such as the reduced mass of the two bodies, the mass ratio between the upper and lower bodies, the spring constant, the control parameters such as the initial contraction of the spring and the wire tension. This property allows the robot to quickly and economically climb up and down stairs, leap over obstacles, and landing softly without complex control. In this paper, the characteristics of hopping motion for the design and control parameters are clarified by both numerical simulations and experiments. Furthermore, using the robot design based on the results the abilities to hop up and down a step, leap over a cable, and land softly are demonstrated.

The close of a 5-year editorship gives opportunity to reflect on the highs and the lows of an editorship. The goal of such reflection is to assist both authors and reviewers in interacting with a biomedical journal, and to foster interest among individuals contemplating an editorship. Among the highs was the privilege of publishing high-quality original scientific work within the scope of the journal; in this instance mechanistic studies of disease. Although review articles and editorials have their reward, it is the publication of original peer-reviewed work that constitutes the true basis for advancing biomedical science. This is the heart of journal publication. Second, the editorial interaction with submitting authors in bringing their work to publication is itself highly rewarding, and can lead to longer-term collegial working relationships between editors and authors. The anonymous expert reviewers also play a key role in bringing outstanding scientific work to successful publication. Collectively, authors, editors, and reviewers constitute an important 'community of science'. Third, working together as an editorial team, especially through the weekly 'journal clubs' that a regular editorial meeting affords, is commended as a key reward of any editorial group taking on journal management. The lows included sifting through submitted manuscripts in which the rigor of science was not satisfactory, and encountering specific instances of compromised scientific integrity--fortunately rare. In both instances, the editorial commitment is to publish high-quality original science; a necessary corollary is identifying those submissions, through rigorous but fair review, which do not meet journal standards. In the end, editorship is a highly rewarding experience, and very much conducive to sustaining the wonder of science that drew us to this profession.

Nestel, Debra

2017-10-01

In this commentary, I review 38 articles published as editorials in Simulation in Healthcare from inception to April 2016. Of the 27 authors, there was a predominance of medical doctors (63%), male authors (67%), and work originating in the United States (86%). The founding Editor-in-Chief Dr David Gaba contributed to half of the editorials. Using inductive thematic analysis, the following five themes were identified: "embedding" simulation, simulation responding to clinical practice, educational considerations for simulation, research practices, and communicating leadership and scholarship about the community. After thematic analysis, the theoretical notion of communities of practice was used to make further meaning of the themes. This theorizing process reveals that editorial content aligns with the features of an evolving community of practice. The editorials seem to have responded to and shaped contemporary simulation practices. The editorial is a powerful forum in which to frame issues relevant to the healthcare simulation community. As the founding Editor-in-Chief, Gaba has made an extraordinary contribution to the Society for Simulation in Healthcare, in these editorials and the broader healthcare simulation community. Under the leadership of the Editor-in-Chief, Dr Mark Scerbo, I am confident that the editorial voice will continue in the true spirit of scholarship.

Full Text Available Welcome to the December issue of EBLIP, the final issue of my first year as Editor-in-Chief. A year which I have thoroughly enjoyed and one where the fears over what to write in my editorials haven’t materialised. This quarter, ethics has featured quite heavily in my working life so I decided to make this the topic of the editorial, sharing some of my thoughts regarding evidence, ethics and how ethical principles are implemented within the EBLIP journal.Ethics are “principles of conduct or standards of behaviour governing an individual or profession” (Library and Information Science Editorial Committee, 2010, and as individuals or professionals we may be governed by various ethical codes. As I'm sure you know, EBLIP originated in the health domain, where ethical values and ethical research feature strongly. Indeed, by its formal definition, research cannot take place unless “ethical approval” from an appropriate committee has been granted. The practicalities of taking research through the ethical approval process can often be time consuming, and those involved in research need to bear this in mind when planning a project. Each committee will have a slightly different form and process (which can add to the frustration of the researcher, but basically will make their decision to approve on the basis that the research includes obtaining informed consent from participants (i.e., participants know what the research is about and what their involvement will mean; that the research will not cause harm to participants; that confidentiality will be maintained; and that the research undertaken is methodologically rigorous and worthwhile. Preparing a proposal for ethical approval, whilst time consuming, makes the researcher think about all aspects of the research and how it is going to be operationalized, which can save lots of time and effort in the long run and may well also improve the research design. These principles are the same whatever

Neurosciences continues to be the leading journal for Neurosciences in Saudi Arabia and the Middle East. In January 2007, Neurosciences was indexed by Thomson ISI in Science Citation Index Expanded online at ISI Web of KnowledgeSM and Neurosciences Citation Index. Since then a significantly increased volume of scientific articles continues to be submitted to the journal by enthusiastic authors, a fact that enriches the scientific contents of the journal. In 2008, we had a total number of website hits of 495,625 with a monthly average of 41,000. We received a total of 155 manuscripts, with a monthly average of 13 and an average rejection rate of 29%. From these, we published a total of 100 articles, totaling 523 pages for the entire volume. Forty-nine percent of these were original articles. Fifty-eight percent of published articles were from the Eastern Mediterranean Region (EMR), with 30% from KSA, 5% from the Gulf, and 23% from other Arab and EMR countries. The remaining 42% of published articles we received from Canada, India, Japan, Malaysia, and Turkey. The average time from received to acceptance of original articles was 4 months and 4.9 months for acceptance to publication. Reasons for rejection included unrelated topics, poor contents, or duplicate publication. In addition to our 4 regular issues in 2008, we published a supplement of abstracts presented at the 16th Saudi Neuroscience Symposium. We would like to thank the Editorial and Advisory Board Members for their significant contribution to maintain the standards of Neuroscience and looking forward to their important continued role in achieving our goals for 2009. In 2009, we aim to increase the number of issues to meet the increased load of manuscripts. Our objective is to enrich the scientific Neuroscience material presented by the journal with important topic reviews and regular neuroscience quizzes to achieve PubMed indexing. We will continue to promote our new web-based manuscript submission

Although there has been a continuous increase in the number of women working in the field of medicine, women rarely reach the highest academic positions as full professors or editorial board members. We aimed to determine the proportion of women on the editorial boards of top-ranked medical journals in different medical specialties. We analyzed the gender of editorial board members of 60 top-ranked journals of 12 Thomson Reuters Web of Knowledge Journal Citation Reports categories. A total of 4175 editors were included in our analysis. Only 15.9% (10 of 63) editors-in-chief were female. In the 5 categories, critical care, anesthesiology, orthopedics, ophthalmology and radiology, nuclear medicine and medical imaging, currently not 1 woman holds the position of editor-in-chief. Less than one fifth (17.5%, 719 of 4112) of all editorial board members were women. There were significant differences among the evaluated categories, with the highest percentage of women in the category of medicine, general and internal and the lowest in the category critical care, followed by orthopedics. In every category, the proportion of women as editorial board members was substantially lower than that of men. Women are underrepresented on the editorial boards of major medical journals, although there is a great variability among the journals and categories analyzed. If more women are nominated to serve on editorial boards, they will be a visible sign of continuing progress and serve as important role models for young women contemplating a career in academic medicine.

Bibliometric mapping of scientific articles based on keywords and technical terms in abstracts is now frequently used to chart scientific fields. In contrast, no significant mapping has been applied to the full texts of non-specialist documents. Editorials in Nature and Science are such non-specialist documents, reflecting the views of the two most read scientific journals on science, technology and policy issues. We use the VOSviewer mapping software to chart the topics of these editorials. A term map and a document map are constructed and clusters are distinguished in both of them. The validity of the document clustering is verified by a manual analysis of a sample of the editorials. This analysis confirms the homogeneity of the clusters obtained by mapping and augments the latter with further detail. As a result, the analysis provides reliable information on the distribution of the editorials over topics, and on differences between the journals. The most striking difference is that Nature devotes more attention to internal science policy issues and Science more to the political influence of scientists.

The Journal of Magnetic Resonance has played a prominent role in encouraging synergies between physical insights and biophysical applications. In this Virtual Special Issue (VSI), JMR's associate editor Dr. Robert (Rob) Tycko highlights the state-of-the-art in this area, by presenting a compilation of JMR articles published over recent years that demonstrate the value of indirect detection methods in biosolids NMR. This is a topic that Rob knows only too well, having been one of its founders and main expositors. This thematic VSI also gives a perfect "excuse" for thanking Rob for the seven years that he has served as our card-carrying solids NMR associate editor. His work for the Journal was, like all other NMR endeavors in which Rob has embarked, characterized by utmost excellence. Over the years he contributed numerous ideas and initiatives, while providing editorial judgment in the handling of over 320 individual papers. For all this we in the NMR community wish to extend Rob our sincere thanks; to offer him our best wishes for a continued successful career and happiness in all walks of life, and to express our hope that we can keep on counting on his wisdom and advice as member of our Editorial Board. I would also like to use this opportunity to extend a warm welcome to Chad Rienstra, who will be replacing Rob in his role of associate editor.

Several hypotheses have been proposed to explain the pathomechanisms underlying patellofemoral pain (PFP). Concurrent evaluation of lower limb mechanics in the same PFP population is needed to determine which may be more important to target during rehabilitation. This study aimed to investigate possible differences in rearfoot eversion, hip adduction, and knee flexion during stair ascent; the relationship between these variables; and the discriminatory capability of each in identifying females with PFP. Thirty-six females with PFP and 31 asymptomatic controls underwent three-dimensional kinematic analyses during stair ascent. Between-group comparisons were made for peak rearfoot eversion, hip adduction, and knee flexion. Pearson's correlation coefficients were calculated to evaluate relationships among these parameters. Receiver operating characteristic curves were applied to identify the discriminatory capability of each. Females with PFP ascended stairs with reduced peak knee flexion, greater peak hip adduction and peak rearfoot eversion. Peak hip adduction (>10.6°; sensitivity=67%, specificity=77%) discriminated females with PFP more effectively than rearfoot eversion (>5.0°; sensitivity=58%, specificity=67%). Reduced peak hip adduction was found to be associated with reduced peak knee flexion (r=0.54, p=0.002) in females with PFP. These findings indicate that proximal, local, and distal kinematics should be considered in PFP management, but proximally targeted interventions may be most important. The relationship of reduced knee flexion with reduced hip adduction also indicates a possible compensatory strategy to reduce patellofemoral joint stress, and this may need to be addressed during rehabilitation.

This study examines two newspapers' editorial coverage of issues related to the Healthy People 2010 focus areas and compares the two newspapers. A qualitative study. Two Los Angeles, California, newspapers. The masthead editorials of the Los Angeles Times and La Opinión in the year following the release of Healthy People 2010. A structured data abstraction instrument was used for descriptive coding. Correspondence to 1 of the 28 Healthy People 2010 focus areas determined whether domestic editorials were about health. An ethnographic content analysis. There were 1075 editorials from the Los Angeles Times and 361 from La Opinión; 17% were focused on domestic health issues. Three Healthy People 2010 focus areas dominated: Environmental Health, Injury and Violence Prevention, and Access to Quality Health Services. Ten focus areas did not receive a single mention in the Los Angeles Times, and 19 focus areas lacked editorials in La Opinión. Editorial writers regularly tackled issues related to a Healthy People 2010 focus area. Public health practitioners can meet with their local newspaper editorial board and discuss the nation's health objectives as manifested by Healthy People 2020 and the National Prevention Strategy, thereby promoting policies that support individual and population health.

Relationship between the climbing up and climbing down stairs domain scores on the FES-DMD, the score on the Vignos Scale, age and timed performance of functional activities in boys with Duchenne muscular dystrophy

Full Text Available BACKGROUND: Knowing the potential for and limitations of information generated using different evaluation instruments favors the development of more accurate functional diagnoses and therapeutic decision-making. OBJECTIVE: To investigate the relationship between the number of compensatory movements when climbing up and going down stairs, age, functional classification and time taken to perform a tested activity (TA of going up and down stairs in boys with Duchenne muscular dystrophy (DMD. METHOD: A bank of movies featuring 30 boys with DMD performing functional activities was evaluated. Compensatory movements were assessed using the climbing up and going down stairs domain of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD; age in years; functional classification using the Vignos Scale (VS, and TA using a timer. Statistical analyses were performed using the Spearman correlation test. RESULTS: There is a moderate relationship between the climbing up stairs domain of the FES-DMD and age (r=0.53, p=0.004 and strong relationships with VS (r=0.72, p=0.001 and TA for this task (r=0.83, p<0.001. There were weak relationships between the going down stairs domain of the FES-DMD-going down stairs with age (r=0.40, p=0.032, VS (r=0.65, p=0.002 and TA for this task (r=0.40, p=0.034. CONCLUSION: These findings indicate that the evaluation of compensatory movements used when climbing up stairs can provide more relevant information about the evolution of the disease, although the activity of going down stairs should be investigated, with the aim of enriching guidance and strengthening accident prevention. Data from the FES-DMD, age, VS and TA can be used in a complementary way to formulate functional diagnoses. Longitudinal studies and with broader age groups may supplement this information.

Foot clearance is an important variable for understanding safe stair negotiation, but few studies have provided detailed measures of it. This paper presents a new method to calculate minimal shoe clearance during stair descent and compares it to previous literature. Seventeen healthy young subjects descended a five step staircase with step treads of 300 mm and step heights of 188 mm. Kinematic data were collected with an Optotrak system (model 3020) and three non-colinear infrared markers on the feet. Ninety points were digitized on the foot sole prior to data collection using a 6 marker probe and related to the triad of markers on the foot. The foot sole was reconstructed using the Matlab (version 7.0) "meshgrid" function and minimal distance to each step edge was calculated for the heel, toe and foot sole. Results showed significant differences in minimum clearance between sole, heel and toe, with the shoe sole being the closest and the toe the furthest. While the hind foot sole was closest for 69% of the time, the actual minimum clearance point on the sole did vary across subjects and staircase steps. This new method, and the findings on healthy young subjects, can be applied to future studies of other populations and staircase dimensions. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available Applied linguists paying scholarly attention to newspaper genres have often argued that findings emerging from such studies would be of pedagogical significance because most of the newspaper genres share certain conventional features with school genres. Similarly, this study explored lexical cohesion in newspaper editorials, and it is understood that the findings could help learners in handling persuasive writings. The study sought to identify the dominant sources of lexical cohesion in the editorials, and also to examine how lexical cohesion is utilized to achieve coherence in the editorials. Drawing on Systemic Functional Linguistics (SFL, the study applied Eggins’ (2004 model of lexical cohesion and analyzed 30 editorial texts of 20, 354 words drawn from three major Nigerian newspapers: The Guardian, The Nation, and Vanguard. The analysis revealed 2, 685 ties across 849 sentences. The data demonstrated that the major types of lexical cohesion in the editorials include: repetition (49.5%, expectancy relations (15. 8%, class/sub-class (11%, and synonymy (10.8%. It was further revealed that lexical cohesion devices, which formed into chains (586 and isolated ties (837, were utilized in building coherence in the editorial texts. It was finally shown how findings of the study could be beneficial in ESP, EAP, and EGP learning, especially in persuasive writings.

With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

Editorial Bias in Crowd-Sourced Political Information.

Full Text Available The Internet has dramatically expanded citizens' access to and ability to engage with political information. On many websites, any user can contribute and edit "crowd-sourced" information about important political figures. One of the most prominent examples of crowd-sourced information on the Internet is Wikipedia, a free and open encyclopedia created and edited entirely by users, and one of the world's most accessed websites. While previous studies of crowd-sourced information platforms have found them to be accurate, few have considered biases in what kinds of information are included. We report the results of four randomized field experiments that sought to explore what biases exist in the political articles of this collaborative website. By randomly assigning factually true but either positive or negative and cited or uncited information to the Wikipedia pages of U.S. senators, we uncover substantial evidence of an editorial bias toward positivity on Wikipedia: Negative facts are 36% more likely to be removed by Wikipedia editors than positive facts within 12 hours and 29% more likely within 3 days. Although citations substantially increase an edit's survival time, the editorial bias toward positivity is not eliminated by inclusion of a citation. We replicate this study on the Wikipedia pages of deceased as well as recently retired but living senators and find no evidence of an editorial bias in either. Our results demonstrate that crowd-sourced information is subject to an editorial bias that favors the politically active.

Hajizadeh, Maryam; Hashemi Oskouei, Alireza; Ghalichi, Farzan; Sole, Gisela

2016-06-01

Biomechanical changes have been reported for patients with anterior cruciate ligament deficiency (ACLD) and anterior cruciate ligament (ACL reconstruction) (ACLR), likely due to loss of stability and changes in proprioception and neuromotor control. This review evaluated kinematics and kinetics of ACLD and ACLR knees, compared with those on the contralateral uninjured sides, as well as and those in asymptomatic controls during stair navigation. This is a systematic review and meta-analysis. Electronic database searches were conducted from their original available dates to January 2015. Studies that included participants with ACLD or ACLR and reported knee joint angles or moments during stair ascent or descent were included. Nine studies met the inclusion criteria, and the methodological quality of these was assessed with a modified Downs and Black checklist. Effect sizes for differences between injured leg and uninjured contralateral leg or controls were calculated, and meta-analyses were performed if two or more studies considered the same variable. Quality assessment showed an average (± standard deviation) of 70.3% ± 7.2%. Meta-analysis showed less knee flexion at initial contact for ACLR knees compared with that in contralateral knees during stair ascent, with a moderate effect size and minimal heterogeneity. Knees with ACLD showed less peak knee flexion compared with that on contralateral sides during stair ascent, with minimal heterogeneity. External knee flexion moments were lower for ACLR compared with those in controls and contralateral sides during ascent and descent, whereas these moments were decreased for the ACLD compared with controls only during ascent. Meta-analysis results exhibited moderate/high heterogeneity or small/trivial effect sizes. Differences for kinematics and kinetics for the ACL-injured knees indicate long-term compensatory and asymmetric movement patterns while ascending and descending stairs. Due to the heterogeneity as well as

This study compared biomechanics during stair ascent in replaced and non-replaced limbs of total knee arthroplasty (TKA) patients with control limbs of healthy participants. Thirteen TKA patients and fifteen controls performed stair ascent. Replaced and non-replaced knees of TKA patients were less flexed at contact compared to controls. The loading response peak knee extension moment was greater in control and non-replaced knees compared with replaced. The push-off peak knee abduction moment was elevated in replaced limbs compared to controls. Loading and push-off peak hip abduction moments were greater in replaced limbs compared to controls. The push-off peak hip abduction moment was greater in non-replaced limbs compared to controls. Future rehabilitation protocols should consider the replaced knee and also the non-replaced knee and surrounding joints. Copyright © 2016 Elsevier Inc. All rights reserved.

Framing the challenge of climate change in Nature and Science editorials

Science.gov (United States)

Hulme, Mike; Obermeister, Noam; Randalls, Samuel; Borie, Maud

2018-06-01

Through their editorializing practices, leading international science journals such as Nature and Science interpret the changing roles of science in society and exert considerable influence on scientific priorities and practices. Here we examine nearly 500 editorials published in these two journals between 1966 and 2016 that deal with climate change, thereby constructing a lens through which to view the changing engagement of science and scientists with the issue. A systematic longitudinal frame analysis reveals broad similarities between Nature and Science in the waxing and waning of editorializing attention given to the topic, but, although both journals have diversified how they frame the challenges of climate change, they have done so in different ways. We attribute these differences to three influences: the different political and epistemic cultures into which they publish; their different institutional histories; and their different editors and editorial authorship practices.

Autonomous stair-climbing with miniature jumping robots.

Stoeter, Sascha A; Papanikolopoulos, Nikolaos

2005-04-01

The problem of vision-guided control of miniature mobile robots is investigated. Untethered mobile robots with small physical dimensions of around 10 cm or less do not permit powerful onboard computers because of size and power constraints. These challenges have, in the past, reduced the functionality of such devices to that of a complex remote control vehicle with fancy sensors. With the help of a computationally more powerful entity such as a larger companion robot, the control loop can be closed. Using the miniature robot's video transmission or that of an observer to localize it in the world, control commands can be computed and relayed to the inept robot. The result is a system that exhibits autonomous capabilities. The framework presented here solves the problem of climbing stairs with the miniature Scout robot. The robot's unique locomotion mode, the jump, is employed to hop one step at a time. Methods for externally tracking the Scout are developed. A large number of real-world experiments are conducted and the results discussed.

I am very pleased to be assuming the Editorship of Classical and Quantum Gravity for the next five years. I hope to continue the successful policies that have made this journal well known for its openness to new developments in the field, for the efficiency of its editorial process, and for the quality and importance of its articles. Classical and Quantum Gravity has truly blossomed under the guidance of its previous Editors-in-Chief, Malcolm MacCallum, Kellogg Stelle, Gary Gibbons and Hermann Nicolai. During the past 12 months, a total of 847 manuscripts have been submitted, representing an increase of nearly 50% over the past four years alone. Beginning in 2000, the frequency of publication was increased from 12 to 24 issues per year. The rate of full-text downloads is now 7200 per month, nearly a three-fold increase over four years. For regular manuscripts, the average time between receipt and first decision now stands at only 59 days, the receipt-to-acceptance time is now only 72 days, and the receipt-to-online publication time is only 116 days. The corresponding times for letters are 36 days, 44 days and 62 days, respectively. Much of the improvement in refereeing and publication times can be directly attributed to the state-of-the art Web-based refereeing system, maintained by the able administration of the IOP editorial team, consisting of Andrew Wray, Joe Tennant, Joanne Rowse and Susannah Bruce. Both the growth in journal size and the decrease in publication times have been accomplished without any decrease in quality. As one objective measure of this, the 'impact factor' index of Classical and Quantum Gravity has risen steadily over the past four years. Even more significantly, Classical and Quantum Gravity has undergone major intellectual growth since its founding. In 1984, modern string theory was in the process of being born, the subject of 'loop quantum gravity' did not exist at all, 'new inflation' truly was 'new', and the possibility of observing

Equinus of the ankle is a common deformity in spastic cerebral palsy. Achilles tendon lengthening is one of the effective options for the treatment of equinus deformity. In the study, a new stair-shaped Achilles tendon lengthening (ATL) procedure that preserves of the tendon continuity was performed in 28 tendons with equinus deformity (20 patients, mean age=10.5±2.6 years). The results were compared with a group of patients treated with the Z-lengthening procedure. During the latest follow-up visit, the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot scale score was much higher in the stair-shaped ATL group than in the Z-lengthening group (pantigravity stability and quicker recovery in patients.

Membership on a professional medical society or journal editorial board is a marker of influence and prestige for those in academic medicine. This study presents the first comprehensive quantification of women on these boards and the implications for women in medicine. The numbers of women and men on professional society and journal editorial boards across 28 specialties (March 2004) were counted. The number of women holding multiple roles on these boards and the number of women holding top leadership positions on these boards were counted, and these proportions were compared. Three-thousand-four-hundred-seventy-three individuals on 39 professional medical society boards and 54 journal editorial boards were included. Eighty-three percent (2,884) of board members were male. Men occupied > 80% of top leadership positions on these boards. Thirty-five of the 589 women in the study held multiple roles. Anesthesiology (p women on boards in comparison to the total women in the specialty. Internal medicine, plastic surgery, cardiology and general surgery had nearly equivalent proportions; in otolaryngology and family medicine, female board members slightly exceeded the proportion of women in the field. Women's representation on society and editorial boards does not always reflect their presence in medical specialties, and it is critically lacking in certain specialties. Efforts should be made to attain parity of women leaders on these boards. Further efforts should be made to eliminate barriers to women's leadership in medicine.

Liu, Dongxu; Hua, Zikai; Yan, Xinyi; Jin, Zhongmin

2016-10-01

In this study, the biomechanical characteristic of a newly developed adjustable hemipelvic prosthesis under dynamic loading conditions was investigated using explicit finite element method. Both intact and reconstructed pelvis models, including pelvis, femur and soft tissues, were established referring to human anatomic data using a solid geometry of a human pelvic bone. Hip contact forces during ascending stairs and descending stairs were imposed on pelvic models. Results showed that maximum von Mises stresses in reconstructed pelvis were 421.85 MPa for prostheses and 109.12 MPa for cortical bone, which were still within a low and elastic range below the yielding strength of Ti-6Al-4V and cortical bone, respectively. Besides, no significant difference of load transferring paths along pelvic rings was observed between the reconstructed pelvis and natural pelvis models. And good agreement was found between the overall distribution of maximum principal stresses in trabecular bones of reconstructed pelvis and natural pelvis, while at limited stances, principal stresses in trabecular bone of reconstructed pelvis were slightly lower than natural pelvis. The results indicated that the load transferring function of pelvis could be restored by this adjustable hemipelvic prosthesis. Moreover, the prosthesis was predicted to have a reliable short- and long-term performance. However, due to the occurrence of slightly lower principal stresses at a few stances, a porous structure applied on the interface between the prosthesis and bone would be studied in future work to obtain better long-term stability. © IMechE 2016.

Effect of media relations on audiences: comparing how editorials and advertising influence behavior

Full Text Available A notion, according to which editorials have a bigger communication influence than advertisements, is very common and quite popular in public relations. The said notion is so prevalent (among both public relations and marketing communications experts that it has led to the concept of perceived influence multipliers that point to a stronger editorial influence in comparison to advertising influence (2.5 to 8 times stronger. Based on the described assumption, the aim of this paper was to further explore how the target audience perceives editorial and advertising content. The research problem was to compare the effects of both types of content on behavior and behavioral intent (through four media – Internet, radio, newspapers and television. Respondents were divided into two groups – current users of the service that was in focus (for influence on behavior and potential users (for influence on behavioral intent. Even though current users said that editorials had a bigger influence on their behavior, this difference was not significant. On the other hand, potential users stated that the advertising content shaped their behavioral intent more than did editorials. These results once again show the assumption, according to which editorials have a stronger communication influence than advertisements, to be highly questionable.

Lee, Jinkyu; Hong, Yoon No Gregory; Shin, Choongsoo S

2016-07-01

The mid-foot contact area relative to the total foot contact area can facilitate foot arch structure evaluation. A stair descent motion consistently provides initial fore-foot contact and utilizes the foot arch more actively for energy absorption. The purpose of this study was to compare ankle and knee joint angle, moment, and work in sagittal plane during stair descending between low and high Mid-Foot-Contact-Area (MFCA) ratio group. The twenty-two female subjects were tested and classified into two groups (high MFCA and low MFCA) using their static MFCA ratios. The ground reaction force (GRF) and kinematics of ankle and knee joints were measured while stair descending. During the period between initial contact and the first peak in vertical GRF (early absorption phase), ankle negative work for the low MFCA ratio group was 33% higher than that for the high MFCA ratio group (pcontact and peak dorsiflexion angle (early absorption phase+late absorption phase). The peak ankle dorsiflexion angle was smaller in the low MFCA ratio group (p<0.05). Our results suggest that strategy of energy absorption at the ankle and foot differs depending upon foot arch types classified by MFCA. The low MFCA ratio group seemed to absorb more impact energy using strain in the planar fascia during early absorption phase, whereas the high MFCA ratio group absorbed more impact energy using increased dorsiflexion during late absorption phase.

Stair-related falls of older people cause a substantial financial and social burden. Deterioration of the visual system amongst other factors put older people at a high risk of falling. Improved lighting is often recommended. The aim of this study was to investigate the effect of lighting illuminance on stair negotiation performance in older individuals with visual impairment. Eleven participants aged 60 or over with a vision of 6/18 or worse ascended and descended a staircase under: 50 lx, 100 lx, 200 lx, 300 lx and distributed 200 lx lighting. A motion capture system was used to measure movements of the lower limb. Clearance, clearance variability, temporal and spatial parameters and joint/segment kinematics were computed. There was no effect on clearance or clearance variability. Participants had lower speed, cadence, increased cycle time and stance time in the 50 lx compared to 300 lx and distributed 200 lx lighting in descent. The minimum hip angle in ascent was increased in the 200 lx lighting. Clearance was found to be moderately correlated with balance scores. Individuals with visual impairment adopt precautionary gait in dim lighting conditions. This does not always result in improvements in the parameters associated with risk of falling (e.g. clearance).

Rasnick, Robert; Standifird, Tyler; Reinbolt, Jeffrey A.; Cates, Harold E.

2016-01-01

Total knee replacement (TKR) is commonly used to correct end-stage knee osteoarthritis. Unfortunately, difficulty with stair climbing often persists and prolongs the challenges of TKR patents. Complete understanding of loading at the knee is of great interest in order to aid patient populations, implant manufacturers, rehabilitation, and future healthcare research. Musculoskeletal modeling and simulation approximates joint loading and corresponding muscle forces during a movement. The purpose of this study was to determine if knee joint loadings following TKR are recovered to the level of healthy individuals, and determine the differences in muscle forces causing those loadings. Data from five healthy and five TKR patients were selected for musculoskeletal simulation. Variables of interest included knee joint reaction forces (JRF) and the corresponding muscle forces. A paired samples t-test was used to detect differences between groups for each variable of interest (pknee extension moment and muscle forces during the loading response phase indicates the presence of deficits in TKR in quadriceps muscle force production during stair ascent. This result combined with greater flexor muscle forces resulted in similar compressive JRF during loading response between groups. PMID:27258086

I am honoured to take on the leadership of Plasma Sources Science and Technology (PSST) as the successor to Professor Mark J Kushner, with whom I have had the pleasure to work on the journal for many years. Under Mark's insightful and energetic leadership over the last six years, PSST has cemented its position as the journal of choice within its subject area and is now one of the most successful journals in the field. In this first issue of 2014, I would like to reflect on some of the events and achievements of 2013. At the start of the year the PSST Editorial Board, recognizing the vital importance of atomic, molecular and optical (AMO) data to low-temperature plasma physics, agreed that PSST would accept papers reporting such new data, generated through both experiment and theory. Jonathan Tennyson joined the Editorial Board to represent this area. In March Anne Bourdon joined the Associate Editor team and has since then played a key part in the journal's review process alongside our other Editors. During the autumn, PSST moved to a new editorial management system. In December Deborah O'Connell was awarded the 2013 Hershkowitz Early Career Award and Review and joins the Editorial Board as of 2014. I would also like to thank Miles Turner for his work in leading the drafting of a guide on the details necessary in the reporting of the results of computer simulations; the main conclusions of this report have been incorporated into the journal policy. Overall 2013 has been another successful year for PSST; paper submissions were up by 8% on the previous year and there was the highest ever number of downloads of PSST papers in one year. Another noteworthy feature of 2013 was the continuing improvement in publication times while maintaining our high standards for acceptance and providing expert feedback coupled with encouragement particularly to younger researchers and groups. Largely as a result of the hard work of our referees and Associate Editors, the average time

Shams and Cover-ups: The Spectacle of History in Paul Muldoon’s “Meeting the British” and “My Father and I and Billy Two Rivers”

Full Text Available Paul Muldoon’s poems “Meeting the British” and “My Father and I and Billy Two Rivers” represent history as a space of reversed allegiances.  In these poems, doubling is a constant activity that deceives the viewer or interlocutor.  This deception occurs both in the history of British imperialism and in a technological present in which an Irish father and son must make sense of the shifting and uncertain ground of their own cultural identity.  Behind the veil of the allegiance lurk obscured differences of both identity and power; Muldoon’s poems highlight the importance of being skeptical of all assertions of identity that purport to equate different, opposed and unequal cultural groups.  In the end, a knowledge of history is the most important tool for piercing the veil of deception and seeing clearly the working of difference and resisting the deception that is the weapon of those in power.

They have also facilitated the peer review of submitted manuscripts by identifying reviewers and making recommendations for revisions and publication. These contributions have been essential to the continuing operation and high, scientific quality of the Journal.

Falling up the stairs: the equivalent of 'bashing it with a bible' for an ACL ganglion cyst of the knee.

Science.gov (United States)

Dacombe, Peter Jonathan; Robinson, James

2012-03-27

Intra-articular anterior cruciate ligament (ACL) cysts are rare, the pathogenesis remains unknown, with trauma often implicated. Often asymptomatic, incidental MRI findings, 11% produce symptoms such as pain, locking or instability. Treatment of intra-articular ganglia differs from the traditional 'bash it with a bible' mantra for ganglia elsewhere with surgical debridement generally indicated for symptomatic cases. This case report describes a 43-year-old male car mechanic who presented with a symptomatic ACL cyst diagnosed on MRI. While waiting for surgery the patient fell up his stairs at home, causing forced hyperflexion of his knee. After an initial sharp pain, within 24 h the patient experienced complete resolution of symptoms. Postfall MRI showed no evidence of the initial lesion, leading to our conclusion that for this patient, a fall up the stairs was the equivalent of 'bashing it with a bible' for an ACL ganglion cyst of the knee.

Wide step width reduces knee abduction moment of obese adults during stair negotiation.

Science.gov (United States)

Yocum, Derek; Weinhandl, Joshua T; Fairbrother, Jeffrey T; Zhang, Songning

2018-05-15

An increased likelihood of developing obesity-related knee osteoarthritis may be associated with increased peak internal knee abduction moments (KAbM). Increases in step width (SW) may act to reduce this moment. The purpose of this study was to determine the effects of increased SW on knee biomechanics during stair negotiation of healthy-weight and obese participants. Participants (24: 10 obese and 14 healthy-weight) used stairs and walked over level ground while walking at their preferred speed in two different SW conditions - preferred and wide (200% preferred). A 2 × 2 (group × condition) mixed model analysis of variance was performed to analyze differences between groups and conditions (p < 0.05). Increased SW increased the loading-response peak knee extension moment during descent and level gait, decreased loading-response KAbMs, knee extension and abduction range of motion (ROM) during ascent, and knee adduction ROM during descent. Increased SW increased loading-response peak mediolateral ground reaction force (GRF), increased peak knee abduction angle during ascent, and decreased peak knee adduction angle during descent and level gait. Obese participants experienced disproportionate changes in loading-response mediolateral GRF, KAbM and peak adduction angle during level walking, and peak knee abduction angle and ROM during ascent. Increased SW successfully decreased loading-response peak KAbM. Implications of this finding are that increased SW may decrease medial compartment knee joint loading, decreasing pain and reducing joint deterioration. Increased SW influenced obese and healthy-weight participants differently and should be investigated further. Copyright © 2018. Published by Elsevier Ltd.

Case Study: A Bio-Inspired Control Algorithm for a Robotic Foot-Ankle Prosthesis Provides Adaptive Control of Level Walking and Stair Ascent

Full Text Available Powered ankle-foot prostheses assist users through plantarflexion during stance and dorsiflexion during swing. Provision of motor power permits faster preferred walking speeds than passive devices, but use of active motor power raises the issue of control. While several commercially available algorithms provide torque control for many intended activities and variations of terrain, control approaches typically exhibit no inherent adaptation. In contrast, muscles adapt instantaneously to changes in load without sensory feedback due to the intrinsic property that their stiffness changes with length and velocity. We previously developed a “winding filament” hypothesis (WFH for muscle contraction that accounts for intrinsic muscle properties by incorporating the giant titin protein. The goals of this study were to develop a WFH-based control algorithm for a powered prosthesis and to test its robustness during level walking and stair ascent in a case study of two subjects with 4–5 years of experience using a powered prosthesis. In the WFH algorithm, ankle moments produced by virtual muscles are calculated based on muscle length and activation. Net ankle moment determines the current applied to the motor. Using this algorithm implemented in a BiOM T2 prosthesis, we tested subjects during level walking and stair ascent. During level walking at variable speeds, the WFH algorithm produced plantarflexion angles (range = −8 to −19° and ankle moments (range = 1 to 1.5 Nm/kg similar to those produced by the BiOM T2 stock controller and to people with no amputation. During stair ascent, the WFH algorithm produced plantarflexion angles (range −15 to −19° that were similar to persons with no amputation and were ~5 times larger on average at 80 steps/min than those produced by the stock controller. This case study provides proof-of-concept that, by emulating muscle properties, the WFH algorithm provides robust, adaptive control of level walking at

This issue marks the end of an era for The Astrophysical Journal and for astronomical publishing. Helmut Abt is retiring as Editor-in-Chief after serving for 28 years, a period that saw enormous growth in the Journal and its transformation to the forefront of electronic scientific publishing. In February the ApJ office celebrated the receipt of manuscript number 40,000 under Helmut's tenure, a milestone that testifies to his impact on all of our careers. Although the names at the top of the masthead are changing, the rest of the ApJ team remains nearly unchanged, so the editorial transition should be barely noticeable. Much of the editorial work of the Journal will continue to be performed by our capable staff of Scientific Editors. I am also very fortunate to inherit Helmut's outstanding support staff in Tucson, ably headed by Janice Sexton. Our publications staff in Chicago, led by Julie Steffen, and our electronic publications staff, led by Evan Owens, are unmatched in their dedication and energy, and I have already begun working with them on further improvements to the Journal. And Helmut Abt will continue to serve the Journal over the coming months, overseeing the manuscripts that are still under review and editing the special centennial issue that will appear at the end of this year. In the coming months we will introduce several new features, most of them initiated under Helmut Abt's leadership. These will include an upgraded ApJ homepage, web tools for authors and referees, updated documentation and author instructions, and an attractive new version of the on-line journal itself. Over the longer term we are developing plans for streamlining the publication timescale and for expanding our capabilities for publishing and archiving electronic data.

Depending on the venue, and the extent to which editorial resources are invested in the process, highlighted papers appear as News & Views, Research Highlights, Perspectives, Editors' Choice, IOP Select, Editors' Summary, Spotlight on Optics, Editors' Picks, Viewpoints, Synopses, Editors' Suggestions, etc. Here, we look at the relation between highlighted papers and highly influential papers, which we define at two levels: having received enough citations to be among the (i) top few percent of their journal, and (ii) top 1% of all physics papers. Using multiple linear regression and multilevel regression modeling we examine the parameters associated with highly influential papers. We briefly comment on cause and effect relationships between citedness and highlighting of papers.

In order to be utilized in building inspection, building security, and military reconnaissance, a new type of WMR was designed with a passive linkage-type locomotive mechanism for improved adaptability to rough terrain and stair-climbing without the active control techniques. Two designed concepts, `adaptability' and `passivity', were considered for the design of the linkage-type locomotive mechanism of the WMR. The proposed mechanism, composed of a simple 4-bar linkage mechanism and a limite...

Full Text Available Well, here we are with another full volume published. I have watched this journal grow from an idea to a sustainable, reputable journal with readers and contributors from all over the world. It has grown from a small editorial group to a collection of peer reviewers, Evidence Summary writers, copyeditors, etc., that is eighty-four strong (and counting. I have wavered between wondering whether promoting evidence based librarianship is akin to flogging a dead horse to feeling secure in knowing that we are making a difference. Being involved with this journal has made me look at what I do in a different light and I now approach decisions and change with what I refer to as “structured flexibility”. Following the EBL framework is the structured part, and when it works, it works well. But we all know that there is not always an answer in the literature nor is there a guarantee that implemented evidence based change will work similarly in different environments. That’s where the flexibility comes in.Three years as Editor-in-Chief has been a challenging, enjoyable, time-consuming, and fascinating learning experience. It has provided me with numerous opportunities in terms of speaking engagements, workshop offerings, and valuable discussion and discourse. It has also provided me with research and project ideas that I have had to place on the back burner until a time when I have enough hours in the day. Recognizing that adding additional hours to the day is, well, impossible, I have decided to stepdown from my editorial role to pursue other activities. This was a bittersweet decision, but a necessary one. I am pleased to announce that Denise Koufogiannakis will be taking on the role of Editor-in-Chief for the next term. Denise, as many of you know, has also been involved with this journal since its inception and, after a brief period of reduced involvement, has eagerly stepped up to the plate.

Passada a cerimônia de batismo, é hora de enfrentar a não menos difí­cil tarefa de garantir a consolidação de seu perfil editorial na área de sua competência cientí­fica. Espera-se que os leitores de Galáxia - ou, quem sabe?, seus futuros colaboradores - estejam cada vez mais esclarecidos sobre a opção pela diversidade, tanto aquela que diz respeito à transdisciplinaridade, quanto aquela que acolhe a variedade temática, base da linha editorial que desenhou esse projeto. Concebida como uma constelação - que se explicita na escolha do nome, no design gráfico, nas articulações das áreas envolvidas - Galáxia não se enquadra no perfil das revistas temáticas que se fecham em torno de uma única questão ou de um mesmo objeto, compilando sobre eles os vários pontos de vista ou seus desdobramentos possí­veis. Isso não quer dizer que não haja nela espaço para esse tipo de encaminhamento. Na verdade, Galáxia procurou desenhar um lugar - as sessões - em função dos gêneros que reúnem um conjunto diferenciado de abordagens, assegurando, assim, a transdisciplinaridade. Para os ensaios temáticos projetou o Fórum; para os textos analí­ticos, a sessão Artigos. Notí­cias, Projetos, Diálogos, Entrevistas e outros gêneros que possam ser incorporados no futuro definem as sessões que tanto podem estar centradas num único tema quanto abertas para explorações diversificadas. Cada uma, a seu modo, oscila entre o caráter ensaí­stico, a análise aplicada ou experimentação crí­tico-criativa.

Knee Joint Loads and Surrounding Muscle Forces during Stair Ascent in Patients with Total Knee Replacement.

Directory of Open Access Journals (Sweden)

Robert Rasnick

Full Text Available Total knee replacement (TKR is commonly used to correct end-stage knee osteoarthritis. Unfortunately, difficulty with stair climbing often persists and prolongs the challenges of TKR patents. Complete understanding of loading at the knee is of great interest in order to aid patient populations, implant manufacturers, rehabilitation, and future healthcare research. Musculoskeletal modeling and simulation approximates joint loading and corresponding muscle forces during a movement. The purpose of this study was to determine if knee joint loadings following TKR are recovered to the level of healthy individuals, and determine the differences in muscle forces causing those loadings. Data from five healthy and five TKR patients were selected for musculoskeletal simulation. Variables of interest included knee joint reaction forces (JRF and the corresponding muscle forces. A paired samples t-test was used to detect differences between groups for each variable of interest (p<0.05. No differences were observed for peak joint compressive forces between groups. Some muscle force compensatory strategies appear to be present in both the loading and push-off phases. Evidence from knee extension moment and muscle forces during the loading response phase indicates the presence of deficits in TKR in quadriceps muscle force production during stair ascent. This result combined with greater flexor muscle forces resulted in similar compressive JRF during loading response between groups.

Design: This was randomized control trial. Setting: Infertility Clinic. Patient(s: Sixty infertile PCOS women. Intervention(s: Patients were randomized into the study (SSP – 30 patients and control group (traditional protocol – 30 patients. In the SSP, patients were treated with CC 50 mg/day for 5 days and in nonresponsive patients, the dosage was increased to 100 mg/day for 5 days in the same cycle. Maximum dose of 150 mg was given until the dominant follicle was generated. In control group, the dose increment in nonovulatory cases was done in subsequent cycle. Ultrasonography follow-up was done to detect ovulation. Main Outcome Measure(s: Ovulation rate and duration of treatment. Results: Ovulation (66.7% vs. 50% respectively and pregnancy rates (26.7% vs. 15.7% were similar between the stair step and the control group. The duration of treatment was significantly shorter in stair step compared to traditional protocol (17.23 vs. 53 days. CC 100 mg was the most effective dose for ovulation in either group. There were no significant differences in the systemic side effect. Conclusions: By using SSP, effective treatment is provided in significantly shorter time period without any detrimental effect on the ovulation and pregnancy rates.

Association between stairs in the home and instrumental activities of daily living among community-dwelling older adults.

Science.gov (United States)

Tomioka, Kimiko; Kurumatani, Norio; Hosoi, Hiroshi

2018-06-04

There is insufficient evidence regarding the relationship of home environment with functional capacity among community-dwelling older people without disabilities. We conducted a population-based longitudinal cohort study and examined whether stairs in the home were associated with capability to perform instrumental activities of daily living (IADL) in community-dwelling high-functioning older adults. The target population was individuals aged 65 years or older living in two municipalities in Nara Prefecture in Japan. At the baseline survey, residents who were independent in IADL (n = 6722) were included as survey subjects. Subjects were divided into three groups according to their home type; one-storey residences, walk-up residences, or residences with an elevator. IADL was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Multiple logistic regression analyses stratified by gender were used to calculate the odds ratio (OR) and a 95% confidence interval (CI) for a decline in IADL, with one-storey residences as a reference. Age, studied area, marital status, working status, self-perceived economic status, body mass index, chronic diseases, smoking, drinking, eating habits, basic activities of daily living, cognitive functioning, depression, self-rated health, and social participation were used as covariates. During the 3-year follow-up, 11.6% of the subjects showed a decline in IADL. After adjusting for covariates, women who lived in walk-up residences had a lower risk for IADL decline (adjusted OR = 0.72, 95% CI = 0.52-0.99), while living in a home with an elevator was not associated with IADL decline (adjusted OR = 0.94, 95% CI = 0.49-1.77). In contrast, there was no association between home type and IADL decline in men (walk-up residences, adjusted OR = 0.90, 95% CI = 0.71-1.14; residences with an elevator, adjusted OR = 0.82, 95% CI = 0.39-1.72). The presence of stairs in the home was

Standard Javanese Causatives in online editorials and short stories

Full Text Available This paper explores the distinctive features of the standard Javanese causatives in on-line editorials and short stories. This research is based on written corpus. This written corpus was compiled from articles published in an online newspaper Solo Pos. To analyze the corpus, I have developed a system of manual annotation to identify the features of verb transitivity, the animacy and humanness of the verb, the presence of active, passive and ergative-like clauses and the number of other grammatical and semantic features using a system of tags. Using this annotation, I analyze the data based on dua anlaysis: genre analysis, functional analysis using a quantitative method. The findings show that genre influences the selection of causative types (markers. Also, there exists gawe used as a verb of causation in both editorials and short stories which contradicts to the canonical rule of the Javanese active verb and Malihah’s (2014 findings. The finding also shows that the standard Javanese causative in online editorials and short stories occurs with intransitive verbs. The last finding is that active clause is the relative prominent type of clause which occurs in all marker. In conclusion, the above findings have made contributions to knowledge to Javanese grammar.

Terrorism in the Basque press (1990, 2000, 2008 and 2009. Analysis of newspaper editorials about ETA’s fatal attacks

Directory of Open Access Journals (Sweden)

José-María Caminos-Marcet, Ph.D.

2013-01-01

Full Text Available This article presents an analysis of the editorials published by the Basque press in 1990, 2000, 2008 and 2009, when ETA carried out fatal attacks. The objective is to examine the treatment given by the different Basque newspapers to terrorism in their most important opinion texts, which reflect their ideology. The initial hypothesis is that the editorial line used by the Basque press to address ETA’s attacks has changed remarkably during the analysed years, going from the virtual absence of editorials to the use of editorials as active instruments in the fight against violence. By 2009, the Basque press had finally defined its strategy to combat ETA’s terrorism, and this was perfectly reflected in their editorials.

“The Poet, He Nothing Affirms, and Therefore Never Lieth”? An Analysis of the Editorial Fiction

Eva-Maria Konrad

2015-06-01

Full Text Available Is the editorial fiction a possible challenge to Sir Philip Sidney’s famous defence of the poets? Predicated on an assertion-based definition of lying, this paper discusses two historically consecutive versions of this phenomenon: A closer analysis of Gérard Genette’s category of the disavowing authentic authorial preface reveals that Genette’s arguments cannot defend editorial fictions written by ‘author-editors’ against accusations of lying. Rather, this first version of editorial fictions occasionally embodies lies for which the authors are to be held accountable. Editorial fictions written by ‘character-editors’, in contrast, do not meet the conditions of the assertion-based account of lying with the result that, in this case, neither the author nor the ‘character-editor’ can be accused of lying.

Women are underrepresented on the editorial boards of journals in environmental biology and natural resource management

2014-08-01

Full Text Available Despite women earning similar numbers of graduate degrees as men in STEM disciplines, they are underrepresented in upper level positions in both academia and industry. Editorial board memberships are an important example of such positions; membership is both a professional honor in recognition of achievement and an opportunity for professional advancement. We surveyed 10 highly regarded journals in environmental biology, natural resource management, and plant sciences to quantify the number of women on their editorial boards and in positions of editorial leadership (i.e., Associate Editors and Editors-in-Chief from 1985 to 2013. We found that during this time period only 16% of subject editors were women, with more pronounced disparities in positions of editorial leadership. Although the trend was towards improvement over time, there was surprising variation between journals, including those with similar disciplinary foci. While demographic changes in academia may reduce these disparities over time, we argue journals should proactively strive for gender parity on their editorial boards. This will both increase the number of women afforded the opportunities and benefits that accompany board membership and increase the number of role models and potential mentors for early-career scientists and students.

Neste contexto, as políticas públicas na área de ciência e tecnologia, ora em curso, estão no limbo, e é preciso vigilância da comunidade acadêmica para a manutenção do ciclo de ouro vivido nos últimos anos e das garantias da estabilidade institucional e liberdades democráticas. No Google Scholar é observada uma tendência no aumento do índice h5 para 8 e mediana h5 para 3, o que mostra um importante crescimento do indicador em relação ao apresentado no ano passado (h5 = 5 e mediana h5 = 5. Este dado é preliminar, pois sua publicação será efetuada em julho de 2016. O periódico também passa a exigir dos autores o registro no Open Researcher and Contributor ID (ORCID. Isto se deve à necessidade de termos um currículo com informações certificadas disponível na base de dados da HOLOS para facilitar o trabalho de editoria, extração de dados dos autores para repositórios, agências de fomento, entre outras aplicações. É importante informar que os principais periódicos do mundo condicionam os autores realizarem esse registro para a submissão de artigos, se configurando uma tendência da utilização deste registro para o pesquisador no mundo e suas instituições. Neste número são publicadas 33 contribuições, sendo que 29 do Brasil, uma de Cuba, duas da Espanha, uma de Portugal com cooperação com o Brasil e uma da Rússia. Observa-se que 15%  dos artigos publicados são oriundos do exterior. O fluxo de artigos provenientes do exterior observa uma elevação da intensidade de submissões neste último ano.

Full Text Available Introduction. This article analyses the main features and degree of adaptation of the editorials of five newspapers from different European countries to the online environment. Methods. The study is based on the content analysis of the editorials published in the online editions of El País, The Times, Le Monde, Diario de Noticias and Corriere della Sera. Results. In the sample of online newspapers, the editorial genre maintains a privileged position in the online version and can be differentiated from the opinion pieces. In addition, this section retains its function as the institutional voice of the newspapers. Discussion. Despite the importance of the editorial, its role as shaper of public opinion in relation to current affairs is overshadowed by its role as political actor. Conclusions. The online editorial retains the traditional content and format features of the genre, and shows little adaptation to the internet platform and its possibilities to enable citizens’ participation.

Does small equal predatory? Analysis of publication charges and transparency of editorial policies in Croatian open access journals.

2017-06-15

We approach the problem of "predatory" journals and publishers from the perspective of small scientific communities and small journals that may sometimes be perceived as "predatory". Among other characteristics of "predatory" journals two most relevant are their business model and the quality of the editorial work. We analysed 444 Croatian open access (OA) journals in the Hrčak (portal of Croatian scientific journals) digital journal repository for the presence of article processing charges as a business model and the transparency of editorial policies. The majority of journals do not charge authors or require submission or article processing charges, which clearly distinguishes them from "predatory" journals. Almost all Hrčak OA journals have publicly available information on editorial boards, including full names and affiliations, and detailed contact information for the editorial office at the Hrčak website. The journal names are unique and cannot be easily confused with another journal or intend to mislead about the journal's origin. While most journals provide information on peer review process, many do not provide guidelines for reviewers or other editorial and publication ethics standards. In order to clearly differentiate themselves from predatory journals, it is not enough for journals from small research communities to operate on non-commercial bases, but also to have transparent editorial policies.

A persistent lack of international representation on editorial boards in environmental biology.

Full Text Available The scholars comprising journal editorial boards play a critical role in defining the trajectory of knowledge in their field. Nevertheless, studies of editorial board composition remain rare, especially those focusing on journals publishing research in the increasingly globalized fields of science, technology, engineering, and math (STEM. Using metrics for quantifying the diversity of ecological communities, we quantified international representation on the 1985-2014 editorial boards of 24 environmental biology journals. Over the course of 3 decades, there were 3,827 unique scientists based in 70 countries who served as editors. The size of the editorial community increased over time-the number of editors serving in 2014 was 4-fold greater than in 1985-as did the number of countries in which editors were based. Nevertheless, editors based outside the "Global North" (the group of economically developed countries with high per capita gross domestic product [GDP] that collectively concentrate most global wealth were extremely rare. Furthermore, 67.18% of all editors were based in either the United States or the United Kingdom. Consequently, geographic diversity-already low in 1985-remained unchanged through 2014. We argue that this limited geographic diversity can detrimentally affect the creativity of scholarship published in journals, the progress and direction of research, the composition of the STEM workforce, and the development of science in Latin America, Africa, the Middle East, and much of Asia (i.e., the "Global South".

Good editorial practice: editors as educators.

Science.gov (United States)

Marusić, M; Marusić, A

2001-04-01

There may be valuable research going on in the developing and financially less-privileged countries, but it usually does not reach international visibility, in spite of a large number of scientific journals in these countries. Such journals are not only invisible but, by perpetuating a vicious circle of inadequacy, may be directly damaging to the local science and research culture. We call for an international action to help journal editors in less privileged countries. International associations of editors may be leaders of these activities by defining, promoting, and perhaps controlling good editorial practice, as a main criterion for international recognition of a journal. However, the editors of small journals have the power and moral obligation to become a stronghold of quality and advancement in their scientific community. Their educational "tools" are editorial integrity and author-friendly policy. Editors can teach the authors study design, statistical analysis, precision, punctuality, research integrity, style and format of writing, and other aspects of scientific communication. The editors of "big", mainstream scientific journals can act as global educators, teaching and providing guidance to editors of small journals. The editors from developed countries as leaders, and editors from less advantageous environments as teachers are the key figures in shaping research communication in less privileged scientific communities.

With many new members joining the CG&A editorial board over the past year, and with a renewed commitment to not only document the state of the art in computer graphics research and applications but to anticipate and where possible foster future areas of scientific discourse and industrial practice, we asked editorial and advisory council members about where they see their fields of expertise going. The answers compiled here aren’t meant to be all encompassing or deterministic when it comes to the opportunities computer graphics and interactive visualization hold for the future. Instead, we aim to accomplish two things: give a more in-depth introduction of members of the editorial board to the CG&A readership and encourage cross-disciplinary discourse toward approaching, complementing, or disputing the visions laid out in this compilation.

Influence of Lower Extremity Muscle Size and Quality on Stair-Climb Performance in Career Firefighters.

Science.gov (United States)

Kleinberg, Craig R; Ryan, Eric D; Tweedell, Andrew J; Barnette, Timothy J; Wagoner, Chad W

2016-06-01

The purpose of this study was to examine the influence of lower extremity muscular size and quality on stair-climb performance (SCP) in career firefighters. Forty-six male career firefighters (age = 37.0 ± 7.2 years; stature = 180.2 ± 6.9 cm; body mass = 108.0 ± 19.8 kg) volunteered for this study. Panoramic ultrasound images of the vastus lateralis and rectus femoris were obtained to determine cross-sectional area (CSA) and echo intensity (EI) of each muscle. The CSA of each muscle was then summed together and normalized to body mass (CSA/BM [QCSA]). Additionally, EI was averaged across both muscles (QEI). Participants then performed a timed and weighted SCP assessment where they ascended and descended 26 stairs 4 times as quickly as possible while wearing a weighted vest (22.73 kg) to simulate the weight of their self-contained breathing apparatus and turnout gear. Bivariate correlations and stepwise regression analyses were used to examine the relationships among variables and the relative contributions of QCSA and QEI to SCP. Partial correlations were used to examine the relationship between QCSA and SCP and QEI and SCP while controlling for age and body mass index (BMI). The results indicated that QCSA and QEI were significantly related to SCP before (r = -0.492, p = 0.001; r = 0.363, p = 0.013, respectively) and after accounting for age and BMI (r = -0.324, p = 0.032; r = 0.413, p = 0.005, respectively). Both QCSA and QEI contributed significantly to the prediction of SCP (r = 0.560, p < 0.001). These findings indicate that lower extremity muscle size and quality are important contributors to critical firefighting tasks, which have been shown to be improved with resistance training.

Canted antiferromagnetism in KNi3[PO3(F,OH)]2[PO2(OH)2]F2 with a stair-case Kagomé lattice

2017-10-01

A new nickel phosphate KNi3[PO3(F,OH)]2[PO2(OH)2]F2 has been synthesized using a modified hydrothermal method. Structural characterizations show that it adopts a 3D framework structure with 2D layers of Ni octahedra in a stair-case Kagomé lattice. The Ni2 octahedron at the inversion center shares two trans-faces with Ni1 octahedra to form a linear trimer (Ni3O8F6) as the basic structural unit. The Ni-trimers are linked between themselves by sharing F-corners and to [PO3(F,OH)] tetrahedral groups by sharing O-corners to form 2D stair-case Kagomé layers, which are parallel to the (100) plane and are stacked along the a-axis. Successive Kagomé layers are combined together by [PO2(OH)2] tetrahedral groups and interstice cations K+. Magnetic measurements reveal that KNi3[PO3(F,OH)]2[PO2(OH)2]F2 exhibits a canted antiferromagnetic ordering with a ferromagnetic component at low temperatures.

What are the qualifications and selection criteria for women to be appointed to society journal editorial boards?

Science.gov (United States)

Tomizawa, Yasuko

2014-02-01

Japan ranks extremely low in global ranking of gender equality. It is not easy for female doctors to acquire leadership positions in member societies of the Japanese Association of Medical Science (JAMS). Very few women are included on editorial boards of English medical journals in Japan. Furthermore, until last year, there had been no female editors in English language journals of surgical societies. The qualifications and criteria for selecting editorial board members of medical journals should be clarified. Medical journals in Japan would gain diversity by including women on editorial boards in the same proportion as women membership in the corresponding medical societies.

The Metaphors on International Intervention: A Discourse Analysis of the Sri Lankan English Newspaper Editorials

Directory of Open Access Journals (Sweden)

Jeyaseelan Gnanaseelan

2015-07-01

Full Text Available The metaphors used in the Sri Lankan English newspaper editorials during the peace talk time (2001-2007 commenting on the international intervention in the Sri Lankan ethnic conflict reveal community based ideological and attitudinal positions of the newspapers published in Sri Lanka. Metaphors literally contribute to our understanding of reality. The frames and scripts used for legitimization and de-legitimization of the issues related to international intervention and facilitation in the peace talk, peace process and monitoring the ceasefire bring out certain realities comfortable to certain people, groups or communities. The binary positions projected in the editorial discourse are identified. Discourse constitutes power in constructing ideational, textual and interpersonal constructs which are ideological. It can transmit and even legitimize power in society. During the peace talk time, the editorials are expected to develop constructive discourse on conflict intervention and resolution to make a positive impact on legislative changes but they display ‘ethno-nationalist’ tendencies. The study analyzes whether the media has been a part of the problem or a part of the solution. Since newspaper and editorial discourses are the constructions of journalists and editors of the elites, the biased ideologies are “hidden or subtle in expressions and often revealed in mild forms”. This study takes up selected editorials of the Sri Lankan English newspapers which appeared mainly during the Memorandum of Understanding between the Sri Lankan government and the Liberation Tigers of Tamil Eezham during that period, to relate the discourse themes with rhetorical and metaphorical features.

I am excited to begin my new role as Editor-in-Chief at a time when the journal is functioning well and the Editorial Team has a sufficient amount of experience to confidently manage the publishing process, but is young enough to be open to new ideas and make changes without too much angst. Mostly, I hope that the journal can quickly respond to the needs of our readers, authors, and everyone who works to make the journal a success. I am always pleasantly surprised when we put out calls for volunteer help and are overwhelmed with the number of people who are interested in contributing to the journal. I definitely believe that the more people who are involved, the better the end result will be, since more ideas and points of view only strengthen the quality of our endeavour.To kick off this first issue of 2009, we debut a new section called Using Evidence in Practice. This section features brief reports of LIS practitioners' use of evidence to assist with decision making. We hope that this section will attract all the practitioners out there who are trying to incorporate evidence into their daily practice, and want to share some of their successes or struggles with the evidence-based process. The section follows a structured format, so that readers can always expect to be provided with information on a project that includes an overview of the setting, problem, evidence that was used, how change was implemented, the outcome of those changes,and the author’s reflections on trying to implement change by using evidence. I hope these brief reports of “real-life” stories inspire and provide ideas for our readers. Our first article in this section looks at one library’s exploration of the use of folksonomy tags and what the evidence they gathered might mean for the cataloguing of their electronic dissertations and theses collection.I am pleased to announce that we have a new

Full Text Available EDITORIAL Em 2004 a HOLOS opta pela alteração do seu caminho e altera-o para aqueles onde seus artigos são publicados exclusivamente de forma eletrônica e disponibilizados nas nuvens – web. Esta estratégia objetivou ampliar a visibilidade do periódico e, consequentemente, dos artigos publicados. Este processo foi realizado utilizando plataforma de software livre, reduzindo custos e resultando na elevação de downloads e citações de artigos, entre outros. Neste percurso, o número de volumes publicados por ano avançou de forma sistemática, a saber, em 2004 foram publicados dois volumes, entre 2005 a 2008 foram três volumes, em 2009 foram 4 volumes, entre 2010 a 2011 foram quatro volumes e de 2012 aos dias atuais foram seis volumes. Assim, nestes dez anos do periódico online, em ambiente de pleno êxito de relações acadêmicas, foram publicados 46 volumes e 789 artigos. Agora, com caminhos abertos, o foco é consolidar a internacionalização do periódico. Assim, nas edições futuras teremos no mínimo 10% dos artigos em língua inglesa e o periódico estará cada vez mais integrado às ações políticas da Associação Brasileira de Editores Científicos (ABEC.

Asnafi, Solmaz; Gunderson, Tina; McDonald, Robert J; Kallmes, David F

2017-02-01

h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups. Among the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median. Our data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals. Copyright © 2017 The Association of University Radiologists.

EDITORIAL: Greetings from the new Editor-in-Chief

Science.gov (United States)

Bhattacharya, P.

2004-04-01

On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

The second half of the twentieth century and the beginning of the 2000s marked deep changes in the practice of pharmacy in Quebec. The editorials of Québec Pharmacie journal attest these changes on a 50-year period by relating power relationships, conflicts, problems and solutions that concerned pharmacists. This article proposes to analyze the editorial discourse of Québec Pharmacie journal between 1960 and 2013, and to grasp the evolution of the speech. To do so, we analyze the major topics addressed by the editorialists. It appears that Québec Pharmacie’s editorialists aimed the professionalization of pharmacy.

Gender Representation on Journal Editorial Boards in the Mathematical Sciences

Science.gov (United States)

2016-01-01

We study gender representation on the editorial boards of 435 journals in the mathematical sciences. Women are known to comprise approximately 15% of tenure-stream faculty positions in doctoral-granting mathematical sciences departments in the United States. Compared to this group, we find that 8.9% of the 13067 editorships in our study are held by women. We describe group variations within the editorships by identifying specific journals, subfields, publishers, and countries that significantly exceed or fall short of this average. To enable our study, we develop a semi-automated method for inferring gender that has an estimated accuracy of 97.5%. Our findings provide the first measure of gender distribution on editorial boards in the mathematical sciences, offer insights that suggest future studies in the mathematical sciences, and introduce new methods that enable large-scale studies of gender distribution in other fields.

Development of a Stair-Step Multifrequency Synchronized Excitation Signal for Fast Bioimpedance Spectroscopy

Science.gov (United States)

Bian, He; Du, Fangling; Sun, Qiang

2014-01-01

Wideband excitation signal with finite prominent harmonic components is desirable for fast bioimpedance spectroscopy (BIS) measurements. This work introduces a simple method to synthesize and realize a type of periodical stair-step multifrequency synchronized (MFS) signal. The Fourier series analysis shows that the p-order MFS signal f(p, t) has constant 81.06% energy distributed equally on its p  2nth primary harmonics. The synthesis principle is described firstly and then two examples of the 4-order and 5-order MFS signals, f(4, t) and f(5, t), are synthesized. The method to implement the MFS waveform based on a field-programmable gate array (FPGA) and a digital to analog converter (DAC) is also presented. Both the number and the frequencies of the expected primary harmonics can be adjusted as needed. An impedance measurement experiment on a RC three-element equivalent model is performed, and results show acceptable precision, which validates the feasibility of the MFS excitation. PMID:24701563

Stair-Step Particle Flux Spectra on the Lunar Surface: Evidence for Nonmonotonic Potentials?

Science.gov (United States)

Collier, Michael R.; Newheart, Anastasia; Poppe, Andrew R.; Hills, H. Kent; Farrell, William M.

2016-01-01

We present examples of unusual "stair-step" differential flux spectra observed by the Apollo 14 Suprathermal Ion Detector Experiment on the lunar dayside surface in Earth's magnetotail. These spectra exhibit a relatively constant differential flux below some cutoff energy and then drop off precipitously, by about an order of magnitude or more, at higher energies. We propose that these spectra result from photoions accelerated on the lunar dayside by nonmonotonic potentials (i.e.,potentials that do not decay to zero monotonically) and present a model for the expected differential flux. The energy of the cutoff and the magnitude of the differential flux are related to the properties of the local space environment and are consistent with the observed flux spectra. If this interpretation is correct, these surface-based ion observations provide a unique perspective that both complements and enhances the conclusions obtained by remote-sensing orbiter observations on the Moon's exospheric and electrostatic properties.

Full Text Available Communication between management and employees is very important in organizations. However, communication problems might be more felt in any media organization as a whole and in the local media staff in particular. It’s obvious that news workers have everyday communicative interaction with different newsmakers. The article deals with the study and analysis of the communicative interaction between the local editorial creative staff members. Internal and external organizational understanding data are considered. It is determined that the level of organizational communication development influences the local editorial success and employees’ performance. Mutual understanding as the basic criterion of effective communication has several forms. The subject of our study is organizational understanding, that is, a special type of editorial staff relationship which is limited by the boundaries of the organization and is essential for its successful functioning and development. The analysis of empirical data allowed to identify the main problematic aspects and to work out the recommendations for vertical and horizontal communication development.

Texting during stair negotiation and implications for fall risk.

Science.gov (United States)

Hashish, Rami; Toney-Bolger, Megan E; Sharpe, Sarah S; Lester, Benjamin D; Mulliken, Adam

2017-10-01

Walking requires the integration of the sensory and motor systems. Cognitive distractions have been shown to interfere with negotiation of complex walking environments, especially in populations at greater risk for falls (e.g. the elderly). With the pervasiveness of mobile messaging and the recent introduction of augmented reality mobile gaming, it is increasingly important to understand how distraction associated with the simultaneous use of a mobile device impacts navigation of the complex walking environments experienced in daily life. In this study, we investigated how gait kinematics were altered when participants performed a texting task during step negotiation. Twenty participants (13 female, 7 males) performed a series of walking trials involving a step-deck obstacle, consisting of at least 3 texting trials and 3 non-texting trials. When texting, participants ascended more slowly and demonstrated reduced dual-step foot toe clearance. Participants similarly descended more slowly when texting and demonstrated reduced single-step foot heel clearance as well as reduced dual-step foot fore-aft heel clearance. These data support the conclusion that texting during stair negotiation results in changes to gait kinematics that may increase the potential for gait disruptions, falls, and injury. Further research should examine the effect texting has on performing other common complex locomotor tasks, actual fall risk, and the patterns of resulting injury rate and severity when negotiating complex environments.

h-index is useful for quantifying scholarly activity in medicine, but this statistic has not been extensively applied as a measure of productivity in anaesthesia. We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports(®). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus(®). Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (Pcitations, and citations per publication than those at journals with IF less than median. A significant correlation between the median h-index of a journal's editorial board members and its IF (h-index=3.01×IF+6.85; r( 2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

Pero además de esto, este número tiene un significado muy especial: nuestra revista cumple 10 años de existir. Hace aproximadamente 12 años surgió en el seno del Centro Centroamericano de Población la inquietud de ofrecer un espacio para dar a conocer los estudios poblacionales de nuestra región de una manera diferente. Queríamos crear una iniciativa más dinámica, que implicara una mayor rapidez en la gestión editorial, menores costos y un contacto más directo con los autores. Optamos entonces por una opción que apenas iniciaba sus primeros pasos en la Universidad de Costa Rica: la publicación electrónica. De hecho, la nuestra fue una de las primeras revistas electrónicas oficiales de esta noble institución académica. Se tuvo que librar una batalla para lograr romper con los esquemas tradicionales, en los cuales solamente la publicación impresa tenía validez, mientras que las electrónicas se tomaban como de baja calidad. Ha sido un camino largo de evolución, formación, aprendizaje y hoy por hoy se ha demostrado la solidez y seriedad de nuestra revista.PSM ha publicado hasta el día de hoy (116 al 10-1 documentos entre artículos científicos, ensayos, informes técnicos, revisiones bibliográficas y documentos históricos.

I publish in I edit?--Do editorial board members of urologic journals preferentially publish their own scientific work?

Scientists who are members of an editorial board have been accused of preferentially publishing their scientific work in the journal where they serve as editor. Reputation and academic standing do depend on an uninterrupted flow of published scientific work and the question does arise as to whether publication mainly occurs in the self-edited journal. This investigation was designed to determine whether editorial board members of five urological journals were more likely to publish their research reports in their own rather than in other journals. A retrospective analysis was conducted for all original reports published from 2001-2010 by 65 editorial board members nominated to the boards of five impact leading urologic journals in 2006. Publications before editorial board membership, 2001-2005, and publications within the period of time as an editorial board member, 2006-2010, were identified. The impact factors of the journals were also recorded over the time period 2001-2010 to see whether a change in impact factor correlated with publication locality. In the five journals as a whole, scientific work was not preferentially published in the journal in which the scientists served as editor. However, significant heterogeneity among the journals was evident. One journal showed a significant increase in the amount of published papers in the 'own' journal after assumption of editorship, three journals showed no change and one journal showed a highly significant decrease in publishing in the 'own' journal after assumption of editorship.

We compared stair-step artifacts and radiation dose between prospective electrocardiography (ECG)-gated coronary computed tomography angiography (prospective CCTA) and retrospective CCTA using 64-detector CT and determined the optimal padding time (PT) for prospective CCTA. We retrospectively evaluated 183 patients [mean heart rate (HR) <65 beats/min, maximum HR instability <5 beats/min] who had undergone CCTA. We scored stair-step artifacts from 1 (severe) to 5 (none) and evaluated the effective dose in 53 patients with retrospective CCTA and 130 with prospective CCTA (PT 200 ms, n=32; PT 50 ms, n=98). Mean artifact scores were 4.3 in both retrospective and prospective CCTAs. However, statistically more arteries scored <3 (nonassessable) on prospective CCTA (P<0.001). Mean scores for prospective CCTA with 200- and 50-ms PT were 4.1 and 4.3, respectively (no significant difference). The radiation dose of prospective CCTA was reduced by 59.1% to 80.7%. Prospective CCTA reduces the radiation dose and allows diagnostic imaging in most cases but shows more nonevaluable artifacts than retrospective CCTA. Use of 50-ms instead of 200-ms PT appears to maintain image quality in patients with a mean HR <65 beats/min and HR instability of <5 beats/min. (author)

THE FUNCTIONING OF IRONIES FOR AESTHETIC EFFECT IN ROALD DAHL’S SHORT STORY THE LANDLADY

Directory of Open Access Journals (Sweden)

I Wayan Resen

2014-09-01

Full Text Available Artikel ini membicarakan tentang efek estetis yang dicapai melalui berfungsinya ironi yang hadir secara dominan pada cerita pendek The Landlady karya Roald Dahl. Ironi dalam berbagai tipe dan penggunaannya dalam cerita pendek ini berhasil membangun efek ketegangan yang intens pada pembaca sehingga pembaca menjadi penasaran mengenai apa yang akan terjadi selanjutnya. Ketegangan terjadi karena tatkala pembaca dengan jelas melihat keterancaman Billy Weaver sebagai calon korban pembunuhan oleh nyonya rumahnya, Billy Weaver sendiri yang langsung berhadapan dengan nyonya rumahnya justru tidak menyadari niat buruk di balik keramahtamahan nyonya rumahnya itu. Dengan demikian, Billy Weaver pun tidak mengambil kesimpulan seperti yang diharapkan pembaca tentang niat negatif nyonya rumahnya walaupun sinyal-sinyal keterancamannya sudah semakin berakumulasi dari sikap dan prilaku nyonya rumahnya yang jelas terbaca dari balik sikap manis yang dihadirkan di permukaan. Estetika ironi ini terbangun bukan saja melalui sikap dan prilaku serba ironis nyonya rumah tersebut, tetapi juga melalui kesenjangan kesadaran yang ada antara Billy Weaver dan pembaca. Kondisi ironis ini bersumber pada kehidupan bermuka dua nyonya rumah, yakni prilaku yang seolah-olah sangat baik di permukaan namun sesungguhnya sadistik di balik itu. Ketakterdugaan sikap dan prilaku nyonya rumah ini mengejutkan dan menegangkan pembaca. Sesungguhnya, ketegangan pembaca bertambah intens ketika mendapati Billy Weaver tetap lugu-lugu (‘innocent’ saja di hadapan nyonya rumahnya yang semakin mencengkeramkan muslihatnya. Pada keterkejutan dan ketegangan akibat prilaku serba ironis nyonya rumah ini dan pada ketidaksabaran pembaca terhadap kepolosan Billy Weaver inilah terletak estetika cerita pendek ini.

What is and what is not a book: its materiality and editorial processes

Full Text Available In this paper, we propose a discussion on e-books as a marked product, not just as a discursive framework or because its format, but also by an editorial process at least partially distinct from the printed book. Moreover, the concepts of material formats and reading practices help to deal with aspects of reading modes that are in evidence when books and e-books are referred. Devices for reading and reader's experience seem to have a key role in proposing a process for publishing electronic books. It is argued here that, since the editorial processes of the printed book and eBook are partly differentiated, besides offering different size and experience, the book could be considered simply as a metaphor of the new editorial product produced to be read in new devices. If the entered text genres are the same, the objects are not, and thus it can be said that those genres that are published in a book not necessarily characterize it, but other elements of its characterization. The arguments posed here are based on discussions on editing processes (Eco and Carriere, 2010; Darnton, 2010; Chartier,1998, 2000, 2002; and Procopio, 2010. The concepts of formats are based on Távora (2008.

Full Text Available Abstract The Institut National de la Recherche Agronomique (INRA was honoured to welcome scientists from all over the world who attended the International Workshop on major Genes and QTL in Sheep and Goats. Approximately 100 participants from 16 countries were registered, contributing 52 oral or poster presentations. A first session was dedicated to the tools available for identifying and localising major genes or QTL in these two species. Molecular techniques, marker panels, radiation hybrids, genome physical maps, and BAC libraries were presented along with genetic, comparative and cytogenetic maps. A second and largest session concerned different traits for which major genes or QTL have been found, i.e., ovulation and other reproduction traits, milk and meat characters, and resistance to disease and wool production. For each group, a guest's paper focused on one sub-trait gave the state of the art: the history, identification and localisation of sources of monogenic and oligogenic variability, genetic determinism (dominance, imprinting, ..., effects on the phenotype, physiological mechanisms implied, use in populations, etc. The third session was devoted to the strategies for the use of major genes and QTL in populations, while the last session covered future prospects. A CD (available on request to bodin@toulouse.inra.fr of the full proceedings was available, and participants invited to give a main paper also had the opportunity to submit it for publication in this special issue of GSE. Nine articles were jointly selected by the Editorial Board of the journal and by the Guest Editor.

Sweetman, C

This editorial introduces a journal devoted to examination of the implications of cultural issues on gender and development work. The secondary status of women is one of the few universals in the world, with biology used as an excuse (yet the only constraints placed upon a woman by biology are when she is pregnant or breast feeding). Constraints differ among societies, and cultural practices which appeal to tradition reinforce the power of men. Patriarchal societies foster the notion of an ideal woman to insure the paternity of children and preserve the families. Because women have primary responsibility for children, they are also perceived as the guardians of the very culture which reduces their status. Rape and domestic violence are used to enforce women's conformity to a traditional role. Violence against women is also used as a weapon of warfare while religious fundamentalists manipulate religious texts to insure women's subordination. Participation in development efforts, however, can allow women to question their marginalization and to become positive role models for other women. The arts and the media can also be used to challenge the status quo. The views of women from southern nations have also been marginalized by the north, and people with formal education wield more power than those with experience but no qualifications. Multicultural ideals require development agencies to listen to historically ignored voices, to make a longterm commitment to cultural change, and to employ local people. Charges of cultural imperialism can be refuted if the aspirations of southern women are included on the development agenda.

High-Order Sliding Mode-Based Synchronous Control of a Novel Stair-Climbing Wheelchair Robot

Juanxiu Liu

2015-01-01

Full Text Available For the attitude control of a novel stair-climbing wheelchair with inertial uncertainties and external disturbance torques, a new synchronous control method is proposed via combing high-order sliding mode control techniques with cross-coupling techniques. For this purpose, a proper controller is designed, which can improve the performance of the system under conditions of uncertainties and torque perturbations and also can guarantee the synchronization of the system. Firstly, a robust high-order sliding mode control law is designed to track the desired position trajectories effectively. Secondly, considering the coordination of the multiple joints, a high-order sliding mode synchronization controller is designed to reduce the synchronization errors and tracking errors based on the controller designed previously. Stability of the closed-loop system is proved by Lyapunov theory. The simulation is performed by MATLAB to verify the effectiveness of the proposed controller. By comparing the simulation results of two controllers, it is obvious that the proposed scheme has better performance and stronger robustness.

Editorial research and the publication process in biomedicine and health: Report from the Esteve Foundation Discussion Group, December 2012

Marušić, Ana; Malički, Mario; von Elm, Erik

2014-01-01

Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

Permiten, de igual modo, hacer tangible y resguardar en la memoria de lo impreso el ethos de la Universidad: la consolidación de comunidades académicas y la producción de conocimiento. Sin embargo, para la concreción de este propósito, múltiples tareas han de llevar a cabo quienes trajinan detrás de este tipo de publicaciones: la construcción de una política editorial, la consecución y la recepción de artículos, el sostenimiento de una comunidad de pares o árbitros para la evaluación, la coordinación de procesos como la revisión de estilo, la diagramación y la impresión, el logro de su periodicidad...

After a brief discussion about results for occupational exposure in New Zealand and the UK, a short editorial raises a number of questions about personal dosimetry practice. These questions include whether the right people are being monitored and whether less attention should be paid to the monitoring of certain groups of workers who are occupationally exposed to external beta/gamma radiation, and more to the monitoring of workers or members of the general public who are exposed to higher doses from radon daughters, so as to focus attention on the areas where the largest savings in collective dose could be achieved.

Full Text Available O presente artigo aborda e discute a incidência do controle editorial pautado nos interesses do veículo enquanto empresa. Nesse aspecto, expõe-se o atual debate sobre essa questão ligando a Teoria do Jornalismo – e as premissas da ética da profissão – a realidade das redações. Contrapõe-se, portanto, a exigência de conceitos como imparcialidade, verdade e compromisso com o bem público à rotina organizacional das emissoras e jornais. Por fim, apresentam-se os resultados da pesquisa que deu origem a esse artigo. Pesquisa essa que ouviu, por meio de questionário online, 277 jornalistas do Paraná a fim de identificar a percepção desses profissionais em relação às interferências comerciais na definição de pautas. A análise quantitativa revela que há certa apatia por parte dos jornalistas que, embora reconheçam os prejuízos desse tipo de orientação editorial, se submetem às regras a fim de preservar sua imagem perante o mercado de trabalho, tal como tratado na Teoria Organizacional, de Warren Breed (1955. The current article discusses the incidence of editorial control based on the interests of the vehicle as a company. On this feature, the actual debate about this question is developed connecting the Journalism Theory – and the ethical assumptions of the job – to the editorial office reality. It opposes, then, the requirement of concepts like impartiality, truth and commitment with the public good to the organizational routine of the broadcasting stations and newspapers. At last, the results of the researches that originated this article are shown. Research that has received, through an online questionnaire, 277 journalists of Paraná in order to identify the perception of these professionals about the commercial interventions in the definition of the journalistic script. The quantitative analysis reveals that there is some apathy coming from journalists that, even though they recognize the losses of this kind of

The purpose of this study was to quantify the representation of women among the authors and editorial board members of prominent general orthopedics journals and to determine how these proportions have changed over time. Gender was determined for the authors of all original research studies, case reports, and review articles published in 2 prominent general orthopedics journals in 1970, 1980, 1990, 2000, and 2007. Gender was also determined for each individual serving on the editorial boards of these journals during these years. Between 1970 and 2007, the representation of women increased from 0.8% to 6.5% among first authors (P<.001), from 0.0% to 4.3% among last authors (P = .015), and from 1.6% to 5.4% among editorial board members (P = .16). However, the rates of increase observed in orthopedics were lower than those observed in other fields (P<.05). Between 1970 and 2007, female representation increased significantly among physicians publishing in 2 prominent general orthopedics journals, but these rates of increase were lower than those observed in other fields of medicine.

In this editorial, the author notes that this issue of American Psychologist features a pair of important articles related to newly updated standards for reporting research in psychology in scientific journals, covering both quantitative (Appelbaum et al., 2018) and qualitative (Levitt et al., 2018) research. The increasing breadth and complexity of research, and the importance of communicating it effectively, requires user-friendly resources that can be applied widely to scientific studies. These two articles are intended to serve that purpose, and to encourage thoroughness and accuracy in research reporting, for psychologists and other scientists in broader academic communities. The articles, known as the Journal Article Reporting Standards (JARS) reports, are based on the work of a task force appointed by the American Psychological Association (APA) Publications and Communications Board in 2015.

This editorial introduces an issue of a journal which contains articles on the themes of 1) macroeconomic policy and gender relations and 2) income generation projects and empowerment. The opening paper dispels the myth that economic policies are gender-neutral. Another article uses the effects of structural adjustment policies in the Caribbean to illustrate how such policies increase women's burdens because of cuts in social services and pressures on women to provide cheap labor to create export goods. A third article depicts the adverse consequences of a macroeconomic policy in India which favors exports over domestic production. This theme is developed in a paper which challenges the notion that export-oriented development strategies provide a "trickle down" benefit to the poor. Specific reversals in development advances in Tanzania are linked to the adjustment experience, and the policy of debt repayment at all costs in the Philippines is shown to have an adverse effect on the poor. Other papers from Albania, India, Tanzania, Chile, and Bangladesh highlight how market-oriented reforms have created conditions which are detrimental to women's health. Further research reveals that the touted "feminization of employment" has actually turned out to be a "feminization of unemployment" as gender discrimination in the labor market continues. Papers on income-generating projects spotlight what has been learned about developing a successful income-generation project which recognizes women's "reproductive labor" time demands. Other articles explore barriers faced by women to access to finance and entrepreneurship. By looking beyond economic jargon and false assumptions, the authors of these papers explore how gender relationships are shaped by economic policies and affect policy outcomes and how women are organizing to improve their lives and the health of their communities.

Representations of people with HIV and hepatitis C in editorials of medical journals: discourses and interdiscursive relations.

Science.gov (United States)

Körner, Henrike; Treloar, Carla

2006-01-01

HIV and hepatitis C are blood-borne viruses that cause chronic diseases and affect (in parts of the developed world) predominantly groups that are marginalized and discriminated against: gay men and injecting drug users, respectively. This paper compares the representation of people with HIV and hepatitis C in editorials of medical journals between 1989 and 2001. Analysis is informed by critical discourse analysis and systemic functional linguistics. Hepatitis C editorials draw almost exclusively on the discourse of biomedicine, and patients are either absent or objects in medical procedures. In HIV editorials, a variety of other discourses are integrated into the discourse of biomedicine, thereby creating multidimensional representations of people with HIV as patients and agents in medical procedures, involved in decision making, affected by economic factors, social and cultural issues. The paper discusses the role of the gay community in discursive change and argues that discursive diversity in the representation of people infected with HIV and hepatitis C in medical journals is necessary for health policy, the professional development of healthcare providers, and media reporting to the general public.

Full Text Available Welcome to the first issue of our 5th volume of Evidence Based Library and Information Practice. And what an issue it is! We are very pleased to showcase the keynote addresses from the 5th International Evidence Based Library and Information Practice (EBLIP5 conference that took place in Stockholm, Sweden in July 2009. Andrew Booth, who was Chair of the International Program Committee for the conference, kindly agreed to take on a guest editorial role in gathering these keynote presentations together. I believe it is the first time the EBLIP community has been able to have the keynote papers from an EBLIP conference gathered in this way. Reading these commentaries will give you a true sense of the themes and questions that were woven throughout the conference and will give you lots to think about. For a fuller description and to put this Feature section in context, please be sure to read Andrew’s editorial at the beginning of the section.As we begin our fifth year of publication, submissions of original research articles continue to grow. In this issue we have five original articles on topics ranging from information literacy instruction to cataloguing of e‐books. Two articles look at using communities of practice in the support of evidence based practice; clearly this is an area of emerging research within EBLIP that readers will benefit from learning more about. One of these articles, by Urquhart, Brice, Cooper, Spink, and Thomas, won the Best Oral Presentation award at the EBLIP5 conference.In addition to the original research articles, we also have seven evidence summaries, covering topics such as unionization, information seeking behaviour, and the LIS blogosphere. The EBL101 column tackles critical appraisal, a daunting task that will not seem quite so scary once you’ve read the column!

Does radioiodine cause the ophthalmopathy of Graves' disease; Editorial

This editorial briefly reviews studies which might answer the question as to whether radioiodine treatment causes the ophthalmopathy of Graves' disease. However, the data do not allow any conclusion one way or the other. Other possible causal factors are discussed. Further studies are required to define whether treatment of hyperthyroidism aggravates the ophthalmopathy and whether one thereby is worse than the others and by how much. (UK).

Combined versus individual effects of a valgus knee brace and lateral wedge foot orthotic during stair use in patients with knee osteoarthritis.

2017-05-01

The aim of this study was to investigate the combined and individual biomechanical effects of a valgus knee brace and a lateral wedge foot orthotic during stair ascent and descent in patients with knee osteoarthritis (OA). Thirty-five patients with varus alignment and medial knee OA were prescribed a custom valgus knee brace and lateral wedge foot orthotic. Knee angles and moments in the frontal and sagittal planes were determined from 3D gait analysis completed under four randomized conditions: (1) control (no knee brace or foot orthotic), (2) knee brace, (3) foot orthotic, and (4) combined knee brace and foot orthotic. Additional measures included the vertical ground reaction force, trunk lean, toe out and gait speed. During the combined use of a knee brace and foot orthotic, significant decreases in the knee adduction angle (2.17, 95%CI: 0.50-3.84, p=0.013) and 2nd peak EKAM (0.35, 95%CI: 0.17-0.52, pstair descent; and significant increases in the EKFM were observed during stair ascent (0.54, 95%CI: 0.30-0.78, pstair descent compared to ascent, except for toe out. Findings suggest greater effects on gait when both knee brace and foot orthotic are used together, resulting in a more normal gait pattern. However, whether or not a true change in knee joint load can be inferred when using these orthoses remains unclear. Further research is required to determine the clinical importance of the observed changes. Copyright © 2017. Published by Elsevier B.V.

Since that time our world has changed quite a bit, and so have the boundary conditions of science publishing. However, one thing has not changed: then as now, the general policy and development of a respectable scientific journal should be determined by a board of independent scientists, who volunteer to assume responsibility for the scientific content of the journal, to assure a fair and critical peer review process for all submitted manuscripts, and, in cases of conflict, to finally decide which papers will be published and which will not.As a matter of fact, an international Board of Editors which consists of scientists coming from different countries and continents, with a good reputation in their respective community, and without any conflict of interest with the Publisher of the journal is, in my opinion, these days more important than ever. As our daily scientific work becomes increasingly specialized, but at the same time also increasingly interdisciplinary, we are more and more forced to trust the quality and reliability of published scientific results in the literature, without really having a chance to come to an independent opinion on our own. This is one of the reasons why the many recent cases of plagiarism, scientific misconduct, or outright fraud have caused such a high level of public awareness. It is quite clear that without a serious peer review there would be an even larger number of such cases in the literature, and that without the responsible action taken by concerned Journal Editors, many of the revealed cases probably would have remained under the carpet.It is, therefore, a particular pleasure for me to introduce to you on the following pages the current Editorial Board of physica status solidi (b) in the form of a brief curriculum vitae, a

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability-, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors´ Network of the European Society of Cardiology. Resumo O Comitê Internacional de Editores de Revistas Médicas (ICMJE) fornece recomendações para aprimorar o padrão editorial e a qualidade científica das revistas biomédicas. Tais recomendações variam desde requisitos técnicos de uniformização até assuntos editoriais mais complexos e elusivos, como os aspectos éticos do processo científico. Recentemente, foram propostos registro de ensaios clínicos, divulgação de conflitos de interesse e novos critérios de autoria, enfatizando a importância da responsabilidade e da responsabilização. No último ano, lançou-se uma nova iniciativa editorial para fomentar o compartilhamento dos dados de ensaios clínicos. Esta revisão discute essa nova iniciativa visando a aumentar a conscientização de leitores, investigadores, autores e editores filiados à Rede de Editores da Sociedade Europeia de Cardiologia.

Institute of Geochemistry of the Chinese Academy of Sciences (China. The Centre has a clear objective: to ‘translate research outcomes into practices that will lead to the proper management of degraded and mining lands through working closely with communities, government, industry and NGOs.’ The Centre is working on the subject of artisanal and small-scale mining as a key focus area. Artisanal gold mining on the Indonesian islands of Lombok and Sumbawa is today releasing mercury and cyanide into the environment. The discharge of contaminants and associated land degradation is affecting human health and food safety. To support the Centre’s work, IRC-MEDMIND has created the Journal of Degraded and Mining Lands Management, and it is my pleasure to write this first editorial for the journal. The first issue is a collection of eight papers presented during the 1st International Conference on Environmental, Socio-economic, and Health Impacts of Artisanal and Small-Scale Mining which was held in Malang during February 2012. These eight papers have been authored by leading scientists from South-East Asia and Australasia, and describe new initiatives in the management of degraded and mining lands. On behalf of the Journal of Degraded and Mining Lands Management I thank you for reading this first journal issue of Volume 1. The editorial board invites you to support this journal and signals its intention to aspire to high standards of scientific and written excellence. As a result of the generous support of the University of Brawijaya, the Journal will have no page charges. The Journal of Degraded and Mining Lands Management therefore represents a new mechanism to present relevant, high quality and peer reviewed science and commentary to the international community.

PSYCHOLOGY IN FRENCH ACADEMIC PUBLISHING IN THE LATE NINETEENTH CENTURY: ALFRED BINET, EDITORIAL DIRECTOR AT THE SCHLEICHER PUBLISHING HOUSE.

Nicolas, Serge

2015-01-01

To date, historians of psychology have largely ignored the role of academic publishing and the editorial policies of the late nineteenth century. This paper analyzes the role played by academic publishing in the history of psychology in the specific case of France, a country that provides a very interesting and unique model. Up until the middle of the 1890s, there was no collection specifically dedicated to psychology. Alfred Binet was the first to found, in 1897, a collection of works specifically dedicated to scientific psychology. He chose to work with Reinwald-Schleicher. However, Binet was soon confronted with (1) competition from other French publishing houses, and (2) Schleicher's management and editorial problems that were to sound the death knell for Binet's emerging editorial ambitions. The intention of this paper is to encourage the efforts of the pioneers of modern psychology to have their work published and disseminated. © 2015 Wiley Periodicals, Inc.

The Thanksgiving break came and went quickly for the two of us, and before we knew it, December was here. In a moment of retrospective thinking, we stopped and thought about how this Journal has grown from a simple idea into something that is helping shape the emerging field of financial therapy in just a matter of one or two years. How grateful we are to be able to help guide this important outreach function of the Financial Therapy Association. Even though we get caught up in the day-to-day routines of teaching, conducting research, providing service to the profession, and working diligently to produce a world-class journal, we want every reader to know that we are honored to serve as editors and to be, in a minor sense, ambassadors for the financial therapy field.

Full Text Available The ALT Executive Committee has discussed on a number of occasions the question of making ALT-J wholly available in electronic form on our Web site (at present only the editorial and abstracts of papers appear, and even of turning it into a full-blown electronic journal. I have gently but consistently opposed this move, on occasions to the intense irritation of some of my fellow members, and always at the risk of appearing to be a Luddite. Explicitly ('Who, if not we as learning technologists, should be in the forefront of the soon-to-happen electronic-journal revolution?' and implicitly ('It is estimated that within two years, paper-based journals will be considered the dinosaurs of the academic world', I have increasingly come under pressure to accede to an apparently unstoppable, apparently imminent change in the method and form of scholarly publication. I set out here my reasons for my continued resistance.

-Space, we hope to generate a dynamic and interesting vision of the built environment that stands in contrast to journals whose subject matter is contained within a narrow vision of architecture and planning as constraining determinants of social space. While it is our intention to make space available on a continuing basis to a diversity of submissions, as is now the norm we intend to publish occasional ‘themed’ issues that cover particular subjects in significant depth, for example in kampung development, space in traditional societies, the impact of globalisation on local cultures and development control. Additionally, since this journal is being produced by the Masters Program in Architecture at Udayana University in Bali, it is also our intention to use it as a forum for the diversity of problems that now inundate Balinese society, specifically those that affect development and culture as a whole. In the forefront of this debate lies the nemesis of tourism. Its impacts are ubiquitous and variously interpreted on the one hand as destructive of environment and culture yet on the other as a making a massive contribution to the local economy. While Bali’s problems are not original, the island paradise offers a singular laboratory where the conflicts brought by tourism can be studied in significant depth. It is also our intention to generalise our content, not only in subject matter but also in the form in which it is presented. In future issues we will also welcome three other types of submission. First, book reviews (up to 1000 words. Second, viewpoints which provide a new insight or critique of a theory, method, subject matter etc that the author feels is being ignored or is otherwise misinterpreted (1000-2000 words. Third, review articles which not only review a particular book, but cover its history, influences, similar texts and a theoretical critique of content (approx 2-3000 words. We also take this opportunity to welcome our editorial board members, whom we

Revised and enlarged edition: editorial production as an artistic and a literary genre

Full Text Available The appropriation of the expression «revised and enlarged edition», from the traditional publishing jargon, is presented in this article as a hypotheses to characterize contemporary publishing practices. It consid- ers the publication, in all its stages, as a writing space and as a process that never resigns creativity and criticism.These practices are «revised» (revisited because they imply the problematization of practice, through an exploratory attitude or critic, leading to processes and discourses prepared for a permanent review. And «en- larged» because they expand the operations of each editorial production phase, they iden- tify alternative formats and models, they blur traditional roles (author/editor/designer/ reader and question editing as a mere me- diation for the creation, circulation, reception or reading processes. In this article, we will identify some of the principles and emerging phenomena that help us understand editorial production as an artistic or a literary genre.

Editorial and scientific quality in the parameters for inclusion of journals commercial and open access databases

Full Text Available In this article, the parameters used by RedALyC, Catalogo Latindex, SciELO, Scopus and Web of Science for the incorporation of scientific journals in their collections are analyzed with the goal of proving their relation with the objectives of each database in addition of debating the valuation that the scientific society is giving to those systems as decisive of "scientific quality". The used indicators are classified in: 1 Editorial quality (formal aspects or editorial management. 2 Content quality (peer review or originality and 3 Visibility (prestige of editors and editorial use and impact, accessibility and indexing It is revealed that: a between 9 and 16% of the indicators are related to the quality of content; b Lack specificity in their definition and determination of measure systems, and c match the goals of each base, although a marked trend towards formal aspects related and visibility is observed. Thus makes it clear that these systems pursuing their own objectives, making a core of journals of “quality” for its readership. We conclude, therefore, that the presence or absence of a journal in these collections is not sufficient to determine the quality of scientific magazine and its contents parameter.

Full Text Available In this editorial the journal Uniara, we're bringing some reflections on the issues involved in the consolidation of a multidisciplinary character of publication. As discussed earlier, the creation of a multidisciplinary magazine of the University Center of Araraquara intended, in that context, encourage the dissemination of research results and extension produced by its faculty and students. The very transformations and academic evolution of the institution demanded and were reflected in the changes implemented in magazine publishing in form, content, criteria adopted for publication and visibility, enabling an improvement in the scientific quality of the journal. In this process, the journal maintained its multidisciplinary nature, which required the development of a peer database of different areas of expertise to meet the specificities of the articles submitted. The organization of this select group depends not only on knowledge to academic evaluation of manuscripts, such as commitment, always voluntary, the referees with the rules and dates indicated by the editors. This difficulty is being overcome little by little, being necessary to point out what is the contribution of these researchers that has been promoting the development of the quality of this journal. An analysis of articles published in four numbers after the magazine's restructuring process, using as criteria the six areas of categories, namely, communication, rural communities, law, education, business, environment and health, shows a predominance of the theme environment , investigated in several respects, followed by education and health. The diversity of research in the environmental area has shown and reaffirming that the studies on this topic can and are being approached from an interdisciplinary point of view, and are already reflected in environmental preservation actions. This same multi-interdisciplinary approach will be the basis for discussions during the UN

Feedback control of the neuromusculoskeletal system in a forward dynamics simulation of stair locomotion.

Science.gov (United States)

Selk Ghafari, A; Meghdari, A; Vossoughi, G

2009-08-01

The aim of this study is to employ feedback control loops to provide a stable forward dynamics simulation of human movement under repeated position constraint conditions in the environment, particularly during stair climbing. A ten-degrees-of-freedom skeletal model containing 18 Hill-type musculotendon actuators per leg was employed to simulate the model in the sagittal plane. The postural tracking and obstacle avoidance were provided by the proportional-integral-derivative controller according to the modulation of the time rate change of the joint kinematics. The stability of the model was maintained by controlling the velocity of the body's centre of mass according to the desired centre of pressure during locomotion. The parameters of the proposed controller were determined by employing the iterative feedback tuning approach to minimize tracking errors during forward dynamics simulation. Simultaneously, an inverse-dynamics-based optimization was employed to compute a set of desired musculotendon forces in the closed-loop simulation to resolve muscle redundancy. Quantitative comparisons of the simulation results with the experimental measurements and the reference muscles' activities illustrate the accuracy and efficiency of the proposed method during the stable ascending simulation.

Full Text Available In this editorial, I suggest that not only is reading published texts a way of doing ethno­graph­ic research, but also reading concretely realizes itself in the productions of new texts that reproduce the cultural practices that are analyzed in the published text. Reading as ethnographic method is therefore a reflexive project. I provide a dialectical framework for theorizing the reflexive nature of reading. URN: urn:nbn:de:0114-fqs0401390

This year marks the 60th anniversary of the American Psychologist (AP). Since the publication of its first issue in January 1946, AP has served as the flagship journal for the American Psychological Association (APA) and has played an important and unique role for the field of psychology. Because of the quality of the articles published in AP, the journal has evolved into one of the most influential and widely cited publications in psychology. The purpose of this editorial is to outline a revised set of policies for the journal that builds on and expands those developed by previous editors (see, e.g., Fowler, 1993; Goodstein, 1987; Kiesler, 1976; Pallack, 1981). Before outlining these policies, I would like to explore the relative status and influence of AP within the universe of psychological and social science journals. 2006 APA, all rights reserved.
