Age-friendly Cities and Communities has emerged as a significant policy, participative and governance response to ageing and its spatial effects. This paper argues that it has important benefits in mobilising older people, placing age on the urban agenda and building recognition across politicians, policy makers and programme managers. Based on the experience of Belfast (UK), the analysis suggests however, that it needs to be understood within wider urban restructuring processes, the importance of the property economy and how planning practices favour particular groups and modes of development. Drawing on demographic data, policy documents and in-depth interviews, it evaluates the relationship between age and urban regeneration, research-based advocacy and central-local relations in health and place-based care. The paper concludes by highlighting the importance of knowledge in competitive policy arenas and the need to focus on the most excluded and isolated old and where and how they live.

The article analyzes the incorporation of applied learning modules for undergraduate students of the Universidad Nacional Mayor de San Marcos' Administration career to learn more efficiently and dynamically. The Methodology considers the evaluation and review of the criteria taken in a survey to carry out the E-learning Implementation modules. The objective is to determine the factors that influence virtual teaching by validating the students' ability to use a new teaching process to apply any educational topic through this platform. As a result, five factors that influence virtual teaching were determined, validating students' capacity and predisposition to acquire new knowledge through new learning methodologies using virtual media;using these E-learning modules is recommended in conjunction with the Flipped Classroom or B-Learning methodology. It was also determined that only 30% of the students who have taken several virtual courses within their curriculum feel comfortable with this methodology since it requires an entirely didactic and easy to handle system to teach the subject matter.

In Peru, there is a deficit of university students who manage to graduate by the thesis development modality; in the different faculties of public universities, the number of graduates for this modality is low. This research analyses the particular situation of graduates in the faculty of Systems Engineering and Computer Science of the Universidad Nacional Mayor de San Marcos from 2014, where less than 10% of the total graduates were identified, graduate by the modality of thesis support and that more than 90% graduate through various modalities that do not include making a thesis; the consequence of this is the small amount of thesis generated and therefore the low research index as well as the null publication of scientific articles by our graduates. Therefore, this research aims to increase the percentage of graduates by the thesis development modality through collaborative motivation using virtual platforms and support graduates in the publication of scientific articles. At the end of the research, more than 50% of graduates by the thesis development modality were increased; the publication of scientific articles generated by graduates through the thesis development modality based on the results of their research was also increased

This research work proposes the design and application of an organizational model based on two very important and well-known precedents: On the one hand, the so-called Enterprise Architecture (EA), as a powerful methodology of business modeling based on Zachaman’s Framework and, on the other hand, the Unified Process of Rational (UPR), so that together they achieve a synergistic merger, giving rise to the so-called Unified Enterprise Architecture (UEA), in order to articulate all the perspectives and aspects that are part of the original EA with a third dimension formed by the phases and iterative dynamics of the UPR. In this way, the systemic organizational modeling of universities is very useful; however, its application is valid for all types of organizations. The design of the experimental research of the pre-test and post-test type with a control group is defined, a computer application is developed as a prototype and the empirical test is carried out through direct observation for the control group and simulation for the experimental group; results are evaluated based on the management indicators Efficiency, effectiveness and productivity.

Purpose The purpose of this paper is to present the first economic valuation of four environmental attributes of the Yanachaga–Chemillén National Park (PNYCH – Parque Nacional Yanachaga-Chemillén) in Peru. Design/methodology/approach This study included households in three cities adjacent to the PNYCH and assessed the willingness to pay (WTP) for preservation efforts of these natural services to avoid the predicted loss in forest area by 2030 (currently 143,425 hectares per year). Findings The results showed that the average WTP was US$0.695 (2.3197 soles) per household annually. Added to all households in Peru (9 million), this is equivalent to approximately 6.255 million dollars annually. Practical implications The economic valuation of these attributes is complementary to the contingent valuation and can have a significant impact, as this data influences decision-making and public policies focused on conserving forests and biodiversity. Social implications Upon using the choice experiment (CE) model, the attributes that have the most significant impact on inhabitants’ well-being were economic benefits. The flora and fauna coverage attributes were beneficial for the inhabitants of the place because they valued the proposed recovery and conservation program in a positive and differential way. Originality/value From the collection of valuable economic data, the novelty lies in using the CE method, which has not yet been applied in valuations of natural ecosystem services in Peru.

espanolEl presente trabajo tiene como objetivo el desarrollo de un sistema de en la cual se propone sistematizar el proceso de la redaccion y generacion de historiales medicos con los cuales se propone la reduccion del tiempo de la generacion de historiales y la reduccion de recursos fisicos, especialmente en lo que respecta al uso del papel, la cual los especialistas de la salud redactan en el transcurso de una consulta medica, esto ademas implicaria en la optimizacion en la gestion de los historiales medicos. El sistema planteado a desarrollar consiste en la aplicacion del mecanismo de la firma digital en base al metodo de la criptografia asimetrica o tambien llamada criptografia de clave publica. Esta tecnologia se aplicara principalmente mediante la aplicacion de dos herramientas contempladas para el uso de la firma digital: el sistema RSA (Rivest, Shamir y Adleman) y la funcion hash SHA-256. La aplicacion de la firma digital a los historiales medicos se mostrara implementada a traves del manejo de interfaces graficas que esta planteada para que el especialista pueda redactar y manejar los historiales a su conveniencia. El sistema abordara el uso del lenguaje de programacion Python y el conjunto de herramientas OpenSSL para las funciones criptograficas y PyQt5 para el desarrollo a nivel interfaces graficas. Se propone esta solucion debido a que la tecnologia de firma digital se ha planeado y posteriormente se ha estado desarrollando desde la decada de 1980, son en estos ultimos anos que esta tecnologia ha sido tomada mas en cuenta para el manejo de documentos, y como este caso, de los historiales medicos. EnglishThe present work aims to develop a system in which it is proposed to systematize the process of writing and generating medical records which is proposed to reduce the time of generation of records and the reduction of physical resources, especially regarding the use of paper, which health specialists write in the course of a medical consultation, this would also imply the process of optimization in the management of medical records. The proposed system to develop consists of the application of the digital signature mechanism based on the method of asymmetric cryptography or also called public key cryptography. This technology is applied mainly through the application of two tools contemplated for the use of the digital signature: the RSA system (Rivest, Shamir and Adleman) and the SHA-256 hash function. The application of the digital signature to medical records will be implemented through the handling of graphical interfaces that is proposed so that the specialist can write and manage the records at his convenience. The system will address the use of Python programming language and the software libraries OpenSSL applied for cryptographic functions and PyQt5 for development at the graphical interface level. This solution is proposed because digital signature technology has been planned and has been subsequently developed since the 1980s, it is in recent years that this technology has been taken more into account for document management, and like this case, medical records.

This research work has a great influence on the physical security of the urban infrastructure and the citizens of our capital city, that is why it is necessary to apply prevention strategies since our city is located in a very vulnerable area to seismic events, mainly huaycos, floods and landslides, settlements, landslides and other superficial mass movements, so it is necessary to have knowledge of the causes and effects of these phenomena, the different types and carrying capacity of soils in the districts of Metropolitan Lima, in order to contribute to the knowledge of the degree of vulnerability in which urban areas, marginal urban areas, human settlements are exposed. In conclusion, surveys of public servants allowed us to determine that only 55% of them know the meaning of risk and vulnerability, so 45% are totally unaware of these terms. Likewise, surveys of the general public on the lack of a prevention culture, 83% indicated that they did, hence the need to apply a course or training on disaster risk management issues at all educational levels.

The purpose of the research was to determine the influence of industrial wastewater treatment using the Lemna Minor aquatic plant. Certain varieties of macrophyte plants can absorb or retain various contaminants. Thanks to this, it has been determined that the variety known as Lemna Minor presents this type of property. Three treatment trials were carried out varying the amounts of Lemna Minor (100, 200, and 300g). They are keeping constant the retention time of 10 days that were analyzed at 3, 6, and 10 days after the treatment and with a constant volume of the residual effluent. The results indicate that in terms of the parameters that determine organic contamination, BOD was reduced by (61 %); COD was reduced by (68 %) and the concentration of total suspended solids by (61 %).

The purpose of this research was to determine an alternative formula for calculating the Darcy coefficient in turbulent flow in pipes. The proposed alternate formula is an explicit formula that should be used to replace the Colebrook-White formula for calculating the Darcy coefficient in turbulent flow in pipes since it has higher precision than the explicit formulas that are currently in use. In this investigation, the alternate formula was compared with two explicit formulas commonly used in pipe design, the Swamee-Jain and Pavlov formulas. To determining which formula is better, all of them were compared with the Colebrook-White formula. For this, the average percentage and maximum percentage errors of the Darcy coefficient values calculated with each of the explicit formulas were determined, with the values obtained with the Colebrook - White formula. It was determined that the maximum errors in the calculation of the Darcy coefficient concerning the Colebrook-White formula were: 3,104% for the Swamee-Jain formula, 7,973% for the Pavlov formula and 2,740% for the alternate formula.

This paper presents a technical proposal for the application of experimental designs in the construction processes of civil works, specifically in the manufacture of concrete for rigid pavements. Currently is still does not apply these technological advances, or any application of research methods that allows optimizing processes to more satisfactory levels, despite the advantages and benefits they provide in terms of achieving unexpected performance and significant savings of component materials. The experimental design model is a classic statistical model whose objective is to determine if the independent factors influence in a variable of interest in this case the modulus of breakage of the concrete or in another important factor, during the bending test. The answer surface methodology is based on the experimentation in three stages, the results achieved allow locating an optimal area where the adjusted values lead to reduced consumption of them and expanding the strength of the concrete.

The objective of the research is to generate a new formula to determine the variation in prices in a public works contract that allows the financial balance of the counterparts. The methodology for calculating and adjusting the price variation in public works contracts is given as a function of the K factor, which is a number that comes from the calculation of polynomial formulas whose theoretical basis lies in the price indices, which are established in a legal framework of mandatory use of the polynomial formula to determine the K factor, with eight monomials in the budget and the quantity of supplies that exceeds one hundred. It is considered a subjective margin since its elaboration depends on the discretion of the one who elaborates on the polynomial formula. The investigation questions the procedure established by the state regulations for the calculation of the polynomial formula and shows the margin of error that exists between the value obtained by the method set for regulations and that obtained using the entries of the work budget. The result shows the positive variation in inputs, and the prices have increased, with adjustments paid in the contracts with the benefit of contractors.

In software development, sometimes experienced programmers have difficulty determining before performing their tests, which algorithm will work best to solve a particular problem, and the answer to the question will always depend on the type of problem and nature of the data to be used, in this situation, it is necessary to identify which indicator is the most useful for a specific type of problem and especially in route optimization. Currently, there are techniques and algorithms used in Artificial Intelligence, which, however, cannot display their potential without a well-defined data set. The paper seeks to explain and propose an algorithm selection indicator to build a consistent data set, given the lack of availability of data that allows the best route size decision to be made.

To improve the quality of life of the inhabitants of the town of Quichas and promote their sustainable development, we propose an Ecological Research Center. This center allows the restoration and revaluation of biodiversity in the study area. During the exploratory research process, data was collected through observations, interviews and surveys; the areas of direct and indirect influence were delimited, tourist attractions, infrastructure deficiencies and the environmental and ecological situation of the area were identified. As a result of the information analysis, a proposal for sustainable infrastructure was developed with the design and application of bioclimatic architecture techniques and the use of solar energy. For the proposal model, the Sketchup software was used and the results obtained showed us the potential of Quichas for the use of its landscape, biological and environmental resources in productive activities and tourism, as well as for the development of research in sustainable agriculture, considering the dynamics that characterize its systematic geography.

In this article, a recent formulation for real-time simulation is developed combining the strain energy density of the Spring Mass Model (SMM) with the equivalent representation of the Strain Energy Density Function (SEDF). The resulting Equivalent Energy Spring Model (EESM) is expected to provide information in real-time about the mechanical response of soft tissue when subjected to uniaxial deformations. The proposed model represents a variation of the SMM and can be used to predict the mechanical behavior of biological tissues not only during loading but also during unloading deformation states. To assess the accuracy achieved by the EESM, experimental data was collected from liver porcine samples via uniaxial loading and unloading tensile tests. Validation of the model through numerical predictions achieved a refresh rate of 31 fps (31.49 ms of computation time for each frame), achieving a coefficient of determination R2 from 93.23% to 99.94% when compared to experimental data. The proposed hybrid formulation to characterize soft tissue mechanical behavior is fast enough for real-time simulation and captures the soft material nonlinear virgin and stress-softened effects with high accuracy.

The growth of additive manufacturing processes has enabled the production of complex and smart structures. These fabrication techniques have led research efforts to focus on the application of cellular materials, which are known for their thermal and mechanical benefits. Herein, we studied the mechanical behavior of stainless-steel (AISI 316L) lattice structures both experimentally and computationally. The lattice architectures were body-centered cubic, hexagonal vertex centroid, and tetrahedron in two cell sizes and at two different rotation angles. A preliminary computational study assessed the deformation behavior of porous cylindrical samples under compression. After the simulation results, selected samples were manufactured via laser powder bed fusion. The results showed the effects of the pore architecture, unit cell size, and orientation on the reduction in the mechanical properties. The relative densities between 23% and 69% showed a decrease in the bulk material stiffness up to 93%. Furthermore, the different rotation angles resulted in a similar porosity level but different stiffnesses. The simulation analysis and experimental results indicate that the variation in the strut position with respect to the force affected the deformation mechanism. The tetrahedron unit cell showed the smallest variation in the elastic modulus and off-axis displacements due to the cell orientation. This study collected computational and experimental data for tuning the mechanical properties of lattice structures by changing the geometry, size, and orientation of the unit cell.

Objective Summarize the effects of interventions designed to promote physical activity during elementary school recess in children between 5 and 10 years old. Effective school interventions for children can promote physical activity and healthy behaviors. Methods PubMed, Scopus, Bireme, SciELO, Web of Science, PsychINFO, Proquest, Physical Education Index, Sports Discus, and Eric databases were included in the data search. Original intervention articles on physical activity that used regression methods, published between 2000 and 2019 in English, Portuguese and Spanish were analyzed. Analyses were performed in 2019. Outcomes were organized according to the direction of the association by independent variables. Ten articles were considered eligible for data extraction and evaluation. Results Several strategies were used including playground markings, demarcation of physical activities zones, group activities, availability of sports equipment and facilities. Most of the studies were conducted in the United States. Recess periods ranged from 20–94 min per day and intervention time ranged from 6 weeks to 2 years. Recess duration and intervention effects were positively associated with physical activity. Gender (girls) and age (oldest) were negatively associated with physical activity during recess. Conclusions Interventions based on modifications of school environment such as playground markings demarcation of physical activities zones, group activities, availability of sports equipment and facilities are cheap and cost-effective for increasing physical activity in school recess.

Human skin is characterized by rough, elastic, and uneven features that are difficult to recreate using conventional manufacturing technologies and rigid materials. The use of soft materials is a promising alternative to produce devices that mimic the tactile capabilities of biological tissues. Although previous studies have revealed the potential of fillers to modify the properties of composite materials, there is still a gap in modeling the conductivity and mechanical properties of these types of materials. While traditional Finite Element approximations can be used, these methodologies tend to be highly demanding of time and processing power. Instead of this approach, a data-driven learning-based approximation strategy can be used to generate prediction models via neural networks. This paper explores the fabrication of flexible nanocomposites using polydimethylsiloxane (PDMS) with different single-walled carbon nanotubes (SWCNTs) loadings (0.5, 1, and 1.5 wt.%). Simple Recurrent Neural Networks (SRNN), Long Short-Term Memory (LSTM), and Gated Recurrent Units (GRU) models were formulated, trained, and tested to obtain the predictive sequence data of out-of-plane quasistatic mechanical tests. Finally, the model learned is applied to a dynamic system using the Kelvin-Voight model and the phenomenon known as the bouncing ball. The best predictive results were achieved using a nonlinear activation function in the SRNN model implementing two units and 4000 epochs. These results suggest the feasibility of a hybrid approach of analogy-based learning and data-driven learning for the design and computational analysis of soft and stretchable nanocomposite materials.

The automatic detection of facial expressions is an active research topic, since its wide fields of applications in human-computer interaction, games, security or education. However, the latest studies have been made in controlled laboratory environments, which is not according to real world scenarios. For that reason, a real time Facial Expression Recognition System (FERS) is proposed in this paper, in which a deep learning approach is applied to enhance the detection of six basic emotions: happiness, sadness, anger, disgust, fear and surprise in a real-time video streaming. This system is composed of three main components: face detection, face preparation and face expression classification. The results of proposed FERS achieve a 65% of accuracy, trained over 35558 face images..

This study aimed at evaluating the association between class context and the teacher’s behavior with the physical activity (PA) level of Elementary School students during Physical Education (PE) classes. Eighteen PE classes from six schools were assessed. Class context and the teacher’s behavior were measured based on systematic observation, that is, by using the System for Observing Fitness Instruction Time (SOFIT), whereas the students' PA level was measured with accelerometry. Data were treated with descriptive statistics and shown as the percentage of the class time spent in sedentary behavior and at different PA levels. The association between class context and the teacher’s behavior with different PA levels was assessed by applying binary logistic regression. The percentage of students with regard to the structured games (35.8%), skill practice (23.2%) and management (21.7%) represented 80.7% of PE class total time. General instructions (45.5%), management (28.7%) and observation (18.3%) were the most frequent teacher’s types of behavior seen. It was found that the percentage of time students spent in sedentary behavior and at different PA levels during PE classes varied according to the class context and the teachers' behavior. RESUMO O objetivo deste estudo foi testar a associação entre o contexto da aula e o comportamento do professor com o nível de atividade física (AF) de escolares dos anos iniciais do ensino fundamental durante aulas de educação física (EF). Foram avaliadas 18 aulas de EF de seis escolas. O contexto da aula e o comportamento do professor foram avaliados por meio de observação sistemática (SOFIT) enquanto o nível de AF dos escolares foi mensurado por acelerometria. Os dados foram tratados pela estatística descritiva e apresentados como proporção do tempo da aula em comportamento sedentário e nos diferentes níveis de AF. A associação entre contexto da aula e comportamento do professor com os diferentes níveis de AF foi testada pela regressão logística binária. Os escolares passaram mais tempo durante a aula de EF em AFs de intensidade leve (40,8%) e vigorosa (40,9%). A proporção do tempo da aula destinado aos contextos jogo estruturado (35,8%), prática de habilidades (23,2%) e gerenciamento (21,7%) representou 80,7% to tempo total. Os comportamentos mais frequentes do professor foram: instruções gerais (45,5%), gerenciamento (28,7%) e observando (18,3%). Verificou-se que a proporção do tempo dos escolares em comportamento sedentário e nos diferentes níveis de AF durante a aula de EF variaram de acordo com o contexto da aula e o comportamento do professor.

The objective of the paper is to provide a model capable of serving as a basis for retraining a convolutional neural network that can be used to detect COVID-19 cases through spectrograms of coughing, sneezing and other respiratory sounds from infected people. To address this challenge, the methodology was focused on Deep Learning technics worked with a dataset of sounds of sick and non-sick people, and using ImageNet's Xception architecture to train the model to be presented through Fine-Tuning. The results obtained were a precision of 0.75 to 0.80, this being drastically affected by the quality of the dataset at our availability, however, when getting relatively high results for the conditions of the data used, we can conclude that the model can present much better results if it is working with a dataset specifically of respiratory sounds of COVID-19 cases with high quality.

This research paper was developed to implement an intelligent solution for This research paper was developed to implement an intelligent solution for the control of the capacity of commercial establishments in times of COVID-19 using Yolo, which is a Convolutional Neural Network and a Deep Learning algorithm. For the application of this solution, a COCO dataset was used that is used in the implementation of Yolov4. A computer module was developed for the analysis of the flow of people, using Python 3.7, which mainly consists of an algorithm that determines the path and direction (movement) of a person, and this is evaluated in a limit o threshold that acts as the entrance and exit door of the main establishment; that is, it determines whether a person leaves or enters according to their route and direction. The results indicate that it is possible to implement this solution as an additional monitoring module for use as capacity control and with this offer a complete alternative to the owners of commercial establishments. In this way, it seeks to control the maximum capacity allowed due to the pandemic generated by the Sars-Cov.2 virus. The tests were conducted using an AMD Ryzen 7 3750H processor and an NVIDIA GTX 1660 TI video card. The possibility of determining whether the number of people who entered less than the number of people who left exceeds the maximum allowed by the pandemic on 50% of the real capacity.

The objective is to determine the wind potential for wind energy generation as a clean development mechanism (CDM) based on climatic parameters, wind speed, and local density for six daily shifts in May 2019. The months of April and June were taken as controls. Wind speed measurements were made with a digital anemometer at 3m above the terrain. It was found that the kinetic energy of the wind ranged from 28.2228252 J to 123.48404 J. This was verified when wind power densities were calculated— gross, usable and effective with carbon nanotube blades, with ranges from 842.21 to 1544.84 W/m2; 499.43 to 946.09 W/m2; 336.88 to 617.94 W/m2 and 438.00 to 803.30 W/m2 respectively, projected at 10 and 50 m/s as minimum speed values for each one of them. The wind potential of this area is sufficient for the micro and medium electric wind turbines, and they qualify to be considered as CDM.

In order to identify the research that addressed the Academia da Cidade and Academia da Saúde Programs (ACP/ASP), a scoping review was conducted in April 2020 in five electronic databases and in reference lists aiming to identify scientific articles that had data collections carried out in the facilities of the ACP/ASP or, that somehow involved the populations of the localities where the programs were implemented. Of the 321 initial records, the descriptive synthesis consisted of 59 studies, which had as their most frequent characteristics: cross-sectional design, use of quantitative approaches in data collection and analysis, Nutrition as a central topic, and involvement of users (adults and the elderly). In conclusion, longitudinal studies involving all actors (managers, practitioners and users) and covering different health topics, besides promoting the approximation between academia and public power, may be promising in the sense of better evaluating the impact that the program represents in the life of the communities that are attended.

This paper is intended to determine the extent to which the M-learning model with methodological strategies improves the learning of student’s undergraduates of the Systems Engineering career. The method used was developed through a study of quasi-experimental type and conformed by an experimental group composed of 25 students of section B and a control group by 25 students of section A of the subject of Software Design Patterns. of the Autonomous University of Peru. To obtain the results of the inferential analysis, the Student T test and the Mann Whitney U test were used. Likewise, a prestest and a posttest were applied to evidence the learning improved, previously tests of validity and reliability were performed in each case, the corresponding calculations were subsequently made for the test of the hypotheses. After applying the M-learning model with methodological strategies, significant differences were observed (p = 0.000

The “Pantanos de Villa” is a natural habitat that conserves the high biodiversity of species and acts as the lung of the city, which is considered a wetland of international importance. This is being threatened by an inadequate infrastructure existing in the Lucchetti factory that attempts against the biodiversity of wetlands, for which the following project is proposed whose main objective is the mitigation of CO2 caused by polluting gases. Along with this, the integration of the neighbors with the swamps will be encouraged, through the design of an ecological and bio-sustainable park destined for recreational practices and sports, being a pleasant meeting point for families and tourists. With the theme park of clean technologies, the importance of these technologies for the sustainable development of the district will be reflected, without neglecting the natural beauty of the swamps located in front of the park. It will have spaces to enjoy nature, as well as the application of renewable energies. With the construction of this project, more significant economic development will be obtained. Visits to both the park and the swamps will be generated and increased, contributing and motivating the care and conservation of our environment and environmental awareness.

This research allows us to show common problems such as the green surface deficit, citizen insecurity, and lack of essential services that reflect social exclusion risks. To the above added the absence of infrastructure of the services provided by these systems such as recreation and recreation. Together, they are essential factors for the valuation of land use. Therefore, it is proposed to develop an analysis of recreational green areas appropriate to the needs of the city. With it, you will facilitate the realization of inventories that estimate social indicators, economic, and environmental indicators. The importance of planning recreational parks is to involve citizen participation as a necessary strategy to solve the problematic situations that arise; inclusive processes must be ensured, especially to meet the demands of spreading vulnerable social groups. It concludes the need to address green planning with a focus on economic, social, and ecological studies that encourage the involvement of society in this task.

Background The ability to ‘age in place’ is dependent on a range of inter-personal, social and built environment attributes, with the latter being a key area for potential intervention. There is an emerging body of evidence that indicates the type of built environment features that may best support age friendly communities, but there is a need to expand and consolidate this, while generating a better understanding of how on how research findings can be most effectively be translated in to policy and practice. Methods The study is based on two case study cities, Curtiba (Brazil) and Belfast (UK), which have highly contrasting physical, social and policy environments. The study deploys a mix methods approach, mirrored in each city. This includes the recruitment of 300 participants in each city to wear GPS and accelerometers, a survey capturing physical functioning and other personal attributes, as well as their perception of their local environment using NEWS-A. The study will also measure the built environments of the cities using GIS and develop a tool for auditing the routes used by participants around their neighbourhoods. The study seeks to comparatively map the policy actors and resources involved in healthy ageing in the two cities through interviews, focus groups and discourse analysis. Finally, the study has a significant knowledge exchange component, including the development of a tool to assess the capacities of both researchers and research users to maximise the impact of the research findings. Discussion The HULAP study has been designed and implemented by a multi-disciplinary team and integrates differing methodologies to purposefully impact on policy and practice on healthy ageing in high and low-middle income countries. It has particular strengths in its combination of objective and self-reported measures using validated tools and the integration of GPS, accelerometer and GIS data to provide a robust assessment of ‘spatial energetics’. The strong knowledge exchange strand means that the study is expected to also contribute to our understanding of how to maximise research impact in this field and create effective evidence for linking older adult’s physical activity with the social, built and policy environments.

This paper evaluates the implications of ageing for urban planning, connectivity and especially walkability. It draws on the preliminary results of a Newton/ESRC funded research project on physical activity, health and ageing in Belfast (UK) and Curitiba (Brazil). The paper focuses on a critique of the concept of age friendly cities, especially in the context of urban restructuring, a preference for neoliberal policies and planning strategies based on youth cultures and lifestyles. The analysis identifies age neighbourhoods to better understand socio-demographic and spatial change and how many older people are being pushed to more marginal suburban places where assets and connectivity, especially for walking are weak. The paper concludes by highlighting the implications for urban management, land use planning and community mobilisation.

OBJECTIVE: To analyze the moderator effect of socioeconomic status in the association between the perceived environment and active commuting to school. METHODS: A total of 495 adolescents and their parents were interviewed. Perceived environment was operationalized in traffic and crime safety and assessed with the Neighborhood Environment Walkability Scale. Active commuting was self-reported by the adolescents, categorized in walking, bicycling or skating at least one time/week. Socioeconomic status was used as moderator effect, reported from adolescents’ parents or guardians using Brazilian standardized socioeconomic status classification. Analyses were performed with Poisson regression on Stata 12.0. RESULTS: Prevalence of active commuting was 63%. Adolescents with low socioeconomic status who reported “it is easy to observe pedestrians and cyclists” were more likely to actively commute to school (PR = 1.18, 95%CI 1.03–1.13). Adolescents with low socioeconomic status whose parents or legal guardians reported positively to “being safe crossing the streets” had increased probability of active commuting to school (PR = 1.10, 95%CI 1.01–1.20), as well as those with high socioeconomic status with “perception of crime” were positively associated to the outcome (PR = 1.33, 95%CI 1.03–1.72). CONCLUSIONS: Socioeconomic status showed moderating effects in the association between the perceived environment and active commuting to school.

The aim of this study was to analyze the association between perceived barriers for active commuting to school in the form of displacement of adolescents from Curitiba, Brazil. Interviews were conducted in six schools (three public and three private) with 741 adolescents aged 11-18 yrs. Perceived barriers for active commuting were assessed through a questionnaire with seventeen questions. Active commuting was defined as walking or bicycling to or form school at least one day per week. The associations were tested by Poisson regressions with 5% significance level. The prevalence of active commuting was of 42.9% (50.0% in boys and 37.2% in girls, p
