Renewable Modified Cellulose Bearing Chelating Schiff Base for Adsorptive Removal of Heavy Metal Ions and Antibacterial Action
Authors: Saravanan R. , Ravikumar L.
Published: June 2017

A novel approach toward chemically modified cellulose bearing active chelating Schiff base with hydroxyl group (Cell‐Hy) was synthesized. The modified cellulose was examined for its heavy metal ion uptake potential from aqueous solution. The chemical and structural features of the adsorbent were characterized by Fourier transform infrared spectroscopy (FT‐IR), solid state 13C‐NMR, Scanning Electron Microscopy (SEM), and energy dispersive analysis of X‐ray (EDAX) observations. The experimental conditions and adsorption parameters, including pH, initial metal ion concentration, adsorbent dosage, temperature, and contact time were optimized for the removal of Cu(II) and Pb(II) ions. Kinetic parameters, equilibrium adsorption capacities, and correlation coefficients for pseudo‐first‐order, pseudo‐second‐order, and intraparticle diffusion models were carried out. The data obtained from the adsorption of Cu(II) and Pb(II) onto Cell‐Hy were subjected to Langmuir and Freundlich isotherm models. Thermodynamic parameters have also been evaluated. The antibacterial activity of modified cellulose was tested toward specific bacterial species.

Published: June 2017

The motivation for researching combined technology of transosseus osteosynthesis and intramedullary nailing was need to reduce time of treatment, and improve the rehabilitation of patients with long bone defects. Defect-pseudoarthrosis with anatomical shortening of the bone was modeled in an experiment in five adult mongrel dogs. Then nailing, Ilizarov transosseous fixation and osteotomy in proximal metadiaphysis were carried out. Bone-transport was produced according to the traditional principles of academic Ilizarov. Radiological findings showed regenerate with zonal structure, bone sections of which were presented homogeneous shadows with a periosteal osteogenesis. After 30 days of distraction regenerate lost its zonal structure, and acquired a mechanical soundness. By this time also was detected consolidation of pseudarthrosis. We have experience of treatment of six patients with posttraumatic defects of the long bones, according to the described method. At the same time carried out transosseous osteosynthesis and nailing with locking in one bone fragment. The osteotomy was performed for following distraction. After necessary length of the bone was received, the opponent locking was carried out. And external fixation was removed. This technology has allowed not using Ilizarov in fixation period of the treatment.

Published: June 2017

Skeletal dysplasias are challenging for diagnostics and treatment. We present a series of fifteen patients with different forms of skeletal dysplasias with age ranged from 6 to 17 years with variable clinical presentations managed as a part of the project of scientific cooperation between Turner Paediatric Orthopaedic Institute and Orthopaedic Hospital Vienna-Speising. The spectrum of diagnoses included multiple epiphyseal dysplasia, spondyloepiphyseal dysplasia congenita, diastrophic dysplasia, metaphyseal dysplasia, spondylometaphyseal dysplasia, Stickler syndrome, Kniest dysplasia, and anauxetic dysplasia. Complex treatment, which included axial correction and juxta-articular realignment, was performed as a single-stage, or consecutive surgery. Surgical techniques included corrective osteotomies with internal fixation, guided growth technique and external fixation devices. Best results (full axial correction, normal alignment of the joint) were achieved in 8 patients, including 2 patients with metaphyseal dysplasia, 2 patients with multiple epyphyseal dysplasia, 2 patients with spondyloepyphyseal dysplasia, patient with Stickler syndrome and patient with spondylometaphyseal dysplasia. Good results (partial correction at the present time) were seen in 4 patients (2 patients with Kniest dysplasia, 1 - with multiple epyphyseal dysplasia and 1 - with anauxetic dysplasia). Satisfactory results (non-progressive condition in previous progression) were obtained in 2 patients with diastrophic dysplasia, and poor results (progression of the deformity) - in 1 patient with diastrophic dysplasia. Positive results in most of the cases of our series make promising future for usage of complex approach for orthopedic management of children with skeletal dysplasias; advanced international cooperation is productive and helpful for diagnostics and management of rare diseases.

Published: June 2017

Objective - to compare the effectiveness of radiofrequency denervation (RFD) and conservative treatment of patients with hip degenerative diseases. Material and methods. 66 patients with various stages of hip degeneration were followed up for 12 months, including 36 patients who underwent RFD and 30 patients of control group with conservative treatment. Treatment results were assessed using Visual Analogue Scale (VAS) and Harris Hip Score before treatment, during the first day, 2 days later, as well as at 1, 6 and 12 months. Results: RFD patients demonstrated significantly better results compared with conservative group. Patients with coxarthrosis stage I and II, besides higher efficiency had prolonged period of remission, while patients with coxarthrosis stage III returned to the near-baseline level of pain only in 3-6 months. Conclusions: RFD is an effective treatment modality for patients with initial coxarthrosis stages, which helps to reduce significantly the disability period compared with conservative therapy. RFD is the only method of effective hip pain relieve in patients with severe comorbidities allowing to reduce analgesic consumption. This method is minimally invasive, has low cost, permits repeated procedures, making it attractive for both physicians and patients.

The article demonstrates the outcomes of operative treatment of 190 patients with spinal cord injuryof thoracic and lumbar spine for 10 years. Associated injuries were revealed in 96 patients, the mean ISS score being27.5. All patients underwent decompressive and stabilizing interventions using a transpedicular system of “Synthes” production (Saint Petersburg). Ventral interventions were performed in 27 (14.2%) patients. In all cases, decompression of the spinal canalcontents at the level of damage was achieved. In those patients who were operated within two weeks after trauma, transpedicular system allowed for recovery of a form and size of the spinal canal and the damaged vertebral body. The fractures of transpedicular system were observed in patients operated both with only rear and with combined access. The errors and complications, which happened during surgery, did not influence the outcomes of treatment. The outcomes of treatment were assessed according to the neurological statusdynamics (ASIA score), recovery of support ability of the spine, the presence of pain, and patients’ recovery (Е Denis score). Favorable outcomes were achieved in 114 (61.3%) patients, satisfactoryin 53 (28.5%),and poor in 19 (10.2 %).

S. epidermidis is one of the most common cause of implant-associated infections. Infections due to S. epidermidis rarely develops into life-threatening, however, its prevalence and the difficulties in treating constitute a serious financial burden to the health care system. This study is based on the investigation of phenotypic features (ability to biofilm formation and resistance to antibiotics) of S. epidermidis strains isolated from patients with deep surgical site infection after implantation of orthopaedic devices, and on the investigation of the dynamics of clinical and morphological changes during the development of implant-associated infection due to S. epidermidis based on in vivo experimental models. Multidrug-resistance was found in 23% MSSE isolates and 97,3% - MRSE. Vancomycin, linezolid and fosfomycin were the most active in relation to these pathogens. About 40% of the tested isolates were strong biofilm-producing strains. 43,2% of MRSE strains and only 21,4% of MSSE isolates demonstrated strong biofilm production. The proposed experimental model shows that intra-operative infection of implant by multidrug-resistant clinical MRSE strain led to the development of osteomyelitis in rats for 4 weeks after surgery, in spite of the revision operation and installation of antimicrobial cement spacer in the area of bone defect. Thus, S. epidermidis is a clinically significant aetiological factor with high risk of development of infections after major orthopaedic surgery.

Objective: to determine the capabilities and perspectives of island and perforator flaps for soft tissue reconstruction of the hand. Material and methods. Results of treatment of 41 patients with defects of the soft tissue of the hand, treated at the in the period from 2010 to 2013 and operated using the island flaps and perforator flaps (DAP flap). Results and conclusion. In all cases the authors have received positive functional and cosmetic results, which were evaluated using a questionnaire DASH, the average score was 12.3. Digital artery perforator flaps allow close defect covering tissue any surface fingers. The use of perforator flaps allows reconstructing soft tissue defect with the skin of the same anatomical region as identical morphologically lost. The second important advantage is that the DAP flap is not included in the magisterial arteries, allows its use as a recipient for subsequent microsurgical reconstructions.

Published: June 2017

The purpose - to analyze computerized tomography data in patients with recurrent shoulder instability for signs of glenoid dysplasia. Methods. We studied the diagnostic data and the results of surgical treatment of 168 patients (137 men and 31 women) mostly of young age (under 30 years) who addressed to the clinic during the period from 2010 to 2014 with the symptoms of recurrent anterior shoulder instability. A risk group has been defined with alleged glenoid dysplasia in the amount of 27 patients who were studied by glenoid dimensions (height, width, area), glenoid version (anteversion, retroversion) and inclination angle of the glenoid. Results. In 22 cases, there has been a change in the normal anatomy of the glenoid as its excessive anteversion, increased angle of inclination, and decrease of its absolute area. Research has identified a pathogenic role of changes in the normal anatomy of the glenoid because recurrence of chronic instability in some cases after surgery, as well as in cases of nontraumatic instability in patients without anatomic lesions. Conclusions. Dysplastic changes of bony structures of the shoulder represent the risk factor for recurrent instability and can serve as one of the causes of recurrence after surgical treatment. When choosing a treatment strategy in patients of modern population is advisable to suggest the possible presence of dysplastic changes glenoid. In the event of recurrence after surgical treatment is shown holding computerized tomography to rule out dysplastic changes.

Published: June 2017

Basing on scientific publications and original research the authors specified the effect of incorporation and adsorption of different ions and water molecules on physical, chemical and mechanical properties of bioapatite and determined new directions for investigations of intercrystallite interactions in nanoscale. Inner structure of the apatite crystallites more adaptable to chemical substitutions in comparison with other minerals controls their important characteristics such as a size, solubility, hardness, fragility, formability and thermal stability. The water molecules incorporated in crystallites and adsorbed on their surfaces stabilize them. In case the distances between crystallites become shorter than 10 nm the water molecules adsorbed on their surface play dominant role in bonding between the crystallites. This bond determines the main mechanical properties of bones. We bring forward a suggestion that theoretical model developed on the basis of near edge X-ray spectroscopic studies of bones using the contemporary high brilliant sources of X-ray radiation (synchrotrons and X-ray free electrons lasers) will allow to receive new quantitative data on local electronic and atomic structure (coordination numbers, ionic charges, interatomic distances interatomic and intercrystallite forces) of nanoelements in osseous tissue. The investigation results must bring to construction of new morphologically correct model providing deeper understanding of processes occurring in mineral matrix and mechanical properties of bones.

Published: June 2017

Purpose of the study - to evaluate in different groups of patients variability of anatomical changes that may affect the difference in the length of the lower extremities and affect on the results of the preoperative planning. Material and methods. As study material we used long film X-ays of 142 patients. A main group comprised 69 patients with varying severity of hip dysplasia. Control group consisted of 73 patients without hip pathology. All patients were performed long film X-rays, and measurements of relative and absolute lengths of the lower limbs, followed by analysis of the data. Results. Analysis of the measurements showed that none of the patients had absolutely equal length of the lower limbs, even in the control group in 56.2% of the observations noted the absolute difference of the lower extremities length more than 5 mm, and in 9.6% of patients - from 20 to 35 mm. In assessing the difference of the lower extremities length on AP pelvic view in the main group only one patient of 69 had the same length of the legs, and in 61 cases the difference was more than 5 mm, that it was clinically significant. Of practical interest is the fact that in the main group shortening of the operated limb was observed in 51 of 69 patients in AP views of the pelvis, but the results of measurements of the anatomical length of limbs long film X-rays compared with measurements of the relative shortening on the pelvis AP views showed that clinically significant difference exceeding 5 mm between measurements observed in 68.1% of cases. The greatest difference between the measurements of the limbs length on the pelvis AP views and long film X-rays observed in patients with unilateral hip dislocation and averaged 17.0 mm. Conclusion. Performing preoperative planning in patients with dysplasia only on pelvis AP views not allow properly compensate the difference of the lower extremities lengths, which may adversely affect the functional results of surgery and as a result, the patient’s satisfaction. Therefore, planning THA, especially at high hip dislocation, it is necessary to calculate the difference of the lower extremities lengths considering as the difference of the lengths on AP pelvis views and long film X-rays.

Hip arthroplasty is a common surgery, the success of which largely depends on its planning. Traditionally, arthroplasty planning performed on X-ray film, but this method has many shortcomings, including the well-known systematic repression for analogue X-ray systems to digital. The wide range of implant templates for the planning available in numerous of foreign special planning programs for arthroplasty, but all of them are very expensive. A team of authors from Sechenov First Moscow State Medical University, Lomonosov Moscow State University and Petrovsky National Research Centre of Surgery developed an original computer program for hip arthroplasty planning that allows to plan not only in the DICOM format, but also in photographs of traditional X-ray film. In the process of their work, it has been proved that the projection distortion when photographing X-ray applied to the X-ray viewer without a tripod is 1.95%. Practical testing of the planning program was carried out with 316 total hip arthroplasty surgeries. It turned out that for acetabular component the number of matches was 301 (95.3%), and for femoral components - 304 (96.2%). There were no cases of changing the type of components during surgeries. Thus, the created domestic import-substituting planning program allows working with a variety of image formats and making it possible to digitize X-ray film.
Perspectives of Family Members on Using Technology in Youth Mental Health Care: A Qualitative Study
Authors: Lal Shalini , Daniel Winnie , Rivard Lysanne
Published: June 2017

Background

Information and communication technologies (ICTs) are increasingly recognized as having an important role in the delivery of mental health services for youth. Recent studies have evaluated young people’s access and use of technology, as well as their perspectives on using technology to receive mental health information, services, and support; however, limited attention has been given to the perspectives of family members in this regard.

Objective

The aim of this study was to explore the perspectives of family members on the use of ICTs to deliver mental health services to youth within the context of specialized early intervention for a first-episode psychosis (FEP).

Methods

Six focus groups were conducted with family members recruited from an early intervention program for psychosis. Twelve family members participated in the study (target sample was 12-18, and recruitment efforts took place over the duration of 1 year). A 12-item semistructured focus group guide was developed to explore past experiences of technology and recommendations for the use of technology in youth mental health service delivery. A qualitative thematic analysis guided the identification and organization of common themes and patterns identified across the dataset.

Results

Findings were organized by the following themes: access and use of technology, potential negative impacts of technology on youth in recovery, potential benefits of using technology to deliver mental health services to youth, and recommendations to use technology for (1) providing quality information in a manner that is accessible to individuals of diverse socioeconomic backgrounds, (2) facilitating communication with health care professionals and services, and (3) increasing access to peer support.

Conclusions

To our knowledge, this is among the first (or the first) to explore the perspectives of family members of youth being treated for FEP on the use of technology for mental health care. Our results highlight the importance of considering diverse experiences and attitudes toward the role of technology in youth mental health, digital literacy skills, phases of recovery, and sociodemographic factors when engaging family members in technology-enabled youth mental health care research and practice. Innovative methods to recruit and elicit the perspectives of family members on this topic are warranted. It is also important to consider educational strategies to inform and empower family members on the role, benefits, and use of ICTs in relation to mental health care for FEP.
Health App Use Among Individuals With Symptoms of Depression and Anxiety: A Survey Study With Thematic Coding
Authors: Rubanovich Caryn Kseniya , Mohr David C , Schueller Stephen M
Published: June 2017

Background

Researchers have largely turned to commercial app stores, randomized trials, and systematic reviews to make sense of the mHealth landscape. Few studies have approached understanding by collecting information from target end users. The end user perspective is critical as end user interest in and use of mHealth technologies will ultimately drive the efficacy of these tools.

Objective

The purpose of this study was to obtain information from end users of mHealth technologies to better understand the physical and mental health apps people use and for what purposes.

Methods

People with depressive or anxious symptoms (N=176) seeking entry into a trial of mental health and well-being apps for Android devices completed online questionnaires assessing depression and anxiety (Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7), past and current mental health treatment-seeking behavior, overall mobile device use, and use of mobile health apps. Participants reported the physical health and mental health apps on their devices and their reasons for using them. Data were extracted from the participant self-reports and apps and app purposes were coded in order to categorize them.

Results

Participants were largely white, middle-aged females from the Midwest region of the United States recruited via a health care organization and Web-based advertising (135 female, 41 male, mean age 38.64 years, age range 19-75 years.) Over three-quarters (137/176, 77.8%) of participants indicated having a health app on their device. The top 3 kinds of apps were exercise, fitness, and pedometers or heart rate monitoring apps (93/176, 52.8%); diet, food, or calorie counting apps (65/177, 36.9%); and mental health/wellness apps (46/177, 26.1%). The mean number of mobile physical and mental health apps on a participant’s phone was 2.15 (SD 3.195). Of 176 participants, 107 (60.8%) specifically reported the top 5 health apps that they used and their purposes. Across the 107 participants, a total of 285 apps were reported, with 139 being unique apps. The majority of these apps were free (129/139, 92.8%). Almost two-thirds of participants (67/107, 62.6%) reported using health apps at least on a daily basis.

Conclusions

Among those seeking support for their well-being via physical and mental health apps, people are using a variety of health apps. These people use health apps on a daily basis, especially free apps. The most common reason for using a health app is to track some health-related data; for mental health apps specifically, training or habit building was the most popular reason. Understanding the end user perspective is important because it allows us to build on the foundation of previously established mHealth research and may help guide future work in mHealth.

Comunidades de aprendizaje en Comunicación organizacional: un estudio de caso
Authors: Czerwonogora Ada
Published: June 2017

Este trabajo estudia un curso del Postgrado en Comunicación Organizacional (en línea) de la Universidad Católica del Uruguay, con el enfoque del aprendizaje colaborativo mediado. Para ello, se desarrolló una metodología de investigación mixta, con un diseño descriptivo-interpretativo, y se establecieron dos niveles de análisis complementarios para los foros de discusión: participación y análisis de discurso, este último basado en el modelo de Comunidad de Investigación. Se realizó una codificación guiada por conceptos, basada en las categorías e indicadores de la presencia cognitiva, social y docente de este marco conceptual. Los indicadores asociados con la presencia cognitiva evidenciaron comprensión de los temas trabajados en los foros. El análisis de categorías de la presencia docente permitió detectar elementos de los modelos de buenas prácticas. Los indicadores de presencia social señalaron la importancia de la cohesión grupal y sugirieron la existencia de actitudes empáticas y procesos de colaboración, lo que complementó lo observado para la presencia cognitiva.
Un teatro y un cine para el gran público. Accesibilidad y síntesis estilística en la versión fílmica de La fiaca (Fernando Ayala, 1969)
Authors: Sala Jorge
Published: June 2017

El artículo se propone analizar la traslación fílmica, dirigida por Fernando Ayala, de la obra teatral La fiaca, escrita por Ricardo Talesnik. Se busca construir un recorrido doble: por un lado, el estudio de las coincidencias entre los proyectos creativos del director y el dramaturgo, y la importancia de los factores económicos que incidieron en algunas de las elecciones estéticas. Por otro lado —y a partir de una metodología de análisis comparado sobre las estrategias de puesta en escena teatrales y cinematográficas— el trabajo pretende trazar los rasgos singulares que el filme establece con relación a la obra original y con otras producciones de la década del sesenta. Como eje articulador entre ambos aspectos se indaga el rol que cumplió la noción de accesibilidad como mecanismo que permitió ampliar la repercusión masiva de la película. Este mayor alcance se basó fundamentalmente en la recuperación del actor protagónico de la pieza original: Norman Briski.

Perfil y representatividad de la alta función pública del gobierno central de Colombia
Authors: Roth Deubel André Noël , Robayo Corredor Fredy Alejandro
Published: June 2017

Desde el punto de vista de la teoría de la burocracia representativa, la administración pública no se limita a la función clásica de ejecución neutral de las decisiones. Los individuos son portadores de valores, adquiridos a través de un proceso de socialización, que se expresan en una cierta preferencia en sus decisiones. Así, la influencia ejercida en las decisiones políticas y administrativas por los funcionarios públicos, y en particular por los que ocupan los cargos más altos en la jerarquía, se verá orientada por sus valores. El reconocimiento del carácter político y no estrictamente administrativo o técnico de la labor de la alta administración pública hace pertinente indagar por su caracterización social y política. La investigación señala características de género, de origen étnico, geográfico y de formación de la alta función pública, aquí delimitada por los cargos de libre nombramiento y remoción del gobierno central colombiano, perteneciente al gobierno del presidente Santos en el año 2013. En conclusión, se presenta una discusión sobre su representatividad en relación con el conjunto de la sociedad colombiana.
El poder de las entidades territoriales para mejorar la calidad de la educación básica
Authors: Ruiz Pava Guillermo Antonio
Published: June 2017

El proceso de descentralización le otorgó a las entidades territoriales en Colombia la tarea, entre otras, de mejorar la calidad de la educación. Formalmente, se diseñó el Sistema General de Participaciones (SGP) como un mecanismo para otorga a las entidades territoriales los recursos necesarios para cumplir sus nuevas tareas. Aunque los recursos son necesarios, una apropiada coordinación entre niveles de gobierno potencializa el efecto en la calidad educativa de los recursos a disposición de las entidades territoriales. Utilizando una perspectiva multinivel, se utilizan modelos lineales jerárquicos para encontrar los cursos de acción a nivel departamental y municipal que permitan mejorar la calidad de la educación promedio de los municipios. Los resultados sugieren que los recursos propios, tanto a nivel departamental como municipal son efectivos en el aumento de la calidad de la educación si se usan en principio para resolver las necesidades básicas de la población local, mientras que los recursos del SGP muestran una relación positiva con la calidad en la educación pero pequeña en magnitud.
Pharmacological and Phytochemical Evaluation of Calendula officinalis Linn. For Anti-Anxiety Activity
Authors: Anita Rani , Chander Mohan
Published: June 2017

The Plant Calendula officinalis Linn. (Asteraceae), traditionally was found to be used in the treatment of anxiety. Despite a long tradition of use, no systematic pharmacological and phytochemical work has been carried out on this plant. Thus, C. officinalis was subjected to preliminary anti-anxiety screening studies, with a view to ascertain the truth on evidence of its traditional use as anti-anxiety. In the present study, aerial parts of the plant were extracted using solvents in the order of increasing polarity, viz., petroleum ether (60–80°C), chloroform, methanol and distilled water. Elevated plus maze (EPM) was used to evaluate the anti anxiety activity on all the crude extracts on mice. Methanolic extract of C. officinalis at the dose of 100 mg/kg, p.o. was found significant when compared to diazepam, (2mg/kg). Phytochemical screening showed the presence of alkaloids and polyphenols therefore specific methods are used to extract the total alkaloids and polyphenols fractions from the plant material and methanol extract. Polyphenol fraction at the dose of 50 mg/kg, p.o. showed significant anti-anxiety activity.
Forecasting the Electric Energy Supply in Duhok Province using Proposed Methods Based on Wavelet Analysis and Sarima Methods

Published: June 2017

Many applications have been done in the field of using wavelet analysis for time series analysis. In this study, we used the quarterly data of Electric Energy Supply in Duhok Province-Iraq in Megawatt which represents a sample size (46) observations during the period 2004 and 2015.we aim to describe how wavelet de-noising can be used in time series forecasting and improve the forecasting quality through presenting some proposed methods based on wavelet analysis and SARIMA method and applying on real data and make comparison between methods depending on some statistical criteria.Results from the analysis showed the superiority of the three proposed methods and showed that we can get more information from a series when using Wavelet-SARIMA method and this leads to enhance the classical SARIMA model in forecasting. Furthermore, after many empirical experiments with many wavelet families, it has been found that Daubechies, Coiflets, Discrete Meyer(dmey) and Symlet wavelets are very suitable when denoising the data and out of these four wavelet families, the Daubechies and Discrete Meyer performed better.
Observations on the Use of Crash Modification Factor-Corrected Crash Prediction Models to Identify Sites with Promise
Authors: Poppe Mark J.
Published: June 2017

The Highway Safety Manual (HSM) provides guidance on the application of crash prediction models for network screening, evaluation of alternative designs, and evaluation of implemented safety improvements. A variety of models are available. They may be classified as network screening level (or simple models), project level [or crash modification factor (CMF)–corrected models], and evaluation-level models. The use of crash prediction models to identify sites with promise of safety improvement is often based on assessing the difference between the expected number of crashes ( Ne) at a site and the predicted number of crashes ( Np) for similar sites within the population. A large difference between Ne and Np may denote a safety problem and be used to identify and rank sites with promise. The HSM indicates that CMF-corrected models may be used for network screening purposes. However, issues arise in the analysis regarding the definition of similar sites. When CMF-corrected models are used, the definition of similar sites changes with changes in the CMF adjustments particular to each site. Use of ( Ne − Np) for identifying and ranking sites with promise does not work well when the analysis uses a CMF-corrected estimate of Np. A large combined CMF will increase Np and thereby decrease the value ( Ne − Np). But a large combined CMF may point to a site with promise. This paper examines this phenomenon in detail, reviews a case study, and suggests that simple models may be preferable for identifying sites with promise.
Understanding Traffic Safety Culture: Implications for Increasing Traffic Safety
Authors: Tazul Islam Md , Thue Laura , Grekul Jana
Published: June 2017

Despite the success of various engineering, education, and enforcement measures, fatalities and injuries from traffic collisions remain one of the major global problems. It has been advocated that addressing this massive problem requires a fundamental transformation in the traffic safety culture of road users. Measuring and understanding traffic safety culture has gained growing attention in the field of traffic safety. This study, believed to be the first of its kind in Canada, aimed to ( a) measure traffic safety culture related to distracted driving, impaired driving, and speeding; ( b) investigate how perceptions of these major issues are associated with self-reported behavior and support for related enforcement and policy; and ( c) explore the effect of respondents’ sociodemographic characteristics on traffic safety culture. A telephone survey based on a stratified random sample of approximately 1,000 residents in the Edmonton region of Alberta, Canada, was conducted in 2014. Descriptive analysis, multivariate confirmatory factor analysis, and structural equation modeling were performed. The results demonstrate statistically significant correlations among perceived threat to personal safety, acceptability of behaviors, self-reported behaviors, support for enforcement, and support for law and policy. Perceived threat to personal safety has a statistically significant influence on self-reported behavior, support for enforcement, and support for law and policy. Various sociodemographic characteristics have a significant effect on the perceived threat of traffic behaviors to personal safety. The results can be used to guide educational campaigns to transform traffic safety culture from one that is risk receptive to one that is protective.
Coupled Thermo-Hydro-Mechanical Analysis of Freeze–Thaw Behavior of Pavement Structure over a Box Culvert

Published: June 2017

Evaluation of frost heave is essential for good design of a geotechnical structure in cold regions. Frost heave often causes severe roughness and cracking of structures like pavements. To model frost heave around a box culvert, a practical coupled thermo-hydro-mechanical (THM) model is presented. The performance of the proposed THM model, which can predict the freeze–thaw behavior of unsaturated soil, is demonstrated through frost heave tests under different conditions. A pavement structure located above a box culvert was simulated, and the analysis could reproduce phenomena observed in the field, including uneven upheave of the pavement and frost-heaving force induced by frost-susceptible backfill. To mitigate such damages, the mechanism and countermeasure of uneven frost heave were investigated. It was revealed that the freeze–thaw action considerably affects smoothness and failure of the pavement structure. In addition, the use of insulation may reduce roughness and extend the fatigue life of the pavement structure. The findings of this study are useful for minimizing frost heave in geotechnical structures.

Traumatic brain injury (TBI) is thought to be a risk factor for dementia, including dementia due to Alzheimer’s disease (AD). However, the influence of TBI history on the neuropsychological course of AD is unknown and, more broadly, the effect of TBI history on age-related cognitive change is poorly understood. We examined the relationship between history of TBI with loss of consciousness (LOC) history and cognitive change in participants with normal cognition and probable AD, stratified by APOE ɛ 4 allele status. The sample included 706 participants (432 with normal cognition; 274 probable AD) from the National Alzheimer’s Coordinating Center (NACC) dataset that completed the Uniform Data Set evaluation between 2005 and 2014. Normal and probable AD participants with a history of TBI were matched to an equal number of demographically and clinically similar participants without a TBI history. In this dataset, TBI with LOC was defined as brain trauma with brief or extended unconsciousness. For the normal and probable AD cohorts, there was an average of 3.2±1.9 and 1.8±1.1 years of follow-up, respectively. 30.8% of the normal cohort were APOE ɛ 4 carriers, whereas 70.8% of probable AD participants were carriers. Mixed effects regressions showed TBI with LOC history did not affect rates of cognitive change in APOE ɛ 4 carriers and non-carriers. Findings from this study suggest that TBI with LOC may not alter the course of cognitive function in older adults with and without probable AD. Future studies that better characterize TBI (e.g., severity, number of TBIs, history of subconconcussive exposure) are needed to clarify the association between TBI and long-term neurocognitive outcomes.
