Neste artigo reflectimos sobre os modelos de formação de professores, destacando os modelos construtivistas e desenvolvimentistas que consideramos mais adequados a uma formação que pretende responder aos desafios que se colocam ao actual desempenho profissional dos professores. Identificamos alguns dos factores que podem funcionar como inibidores num processo de formação assente nesses paradigmas, centrando a nossa análise nas concepções implícitas dos alunos/futuros professores sobre os processos de ensino e aprendizagem. Apresentam-se e analisam-se essas concepções num grupo de 135 sujeitos, alunos dos cursos de Educação de Infância e Professores do 1º ciclo em três Escolas Superiores de Educação da Região Centro, no início do seu processo de formação. Os resultados, obtidos a partir da aplicação do Questionário sobre Concepções Implícitas dos Professores Acerca de Factores e Processos de Ensino e Aprendizagem- Forma B, construído por Abreu (1998), evidenciam uma disponibilidade conceptual a processos de formação que concretizem estratégias metodológicas assentes em modelos construtivistas.
Nesta comunicação são abordados os principais desafios que a economia do conhecimento coloca, actualmente, aos territórios e analisadas as diferentes abordagens teóricas que, no quadro da chamada economia territorial de inovação, vêm analisando esses fenómenos.
São, também, perspectivados as principais barreiras que, em Portugal, têm vindo a obstar a uma trajectória de inserção mais competitiva na economia-mundo, quer do sector público, quer do sector privado. Uma particular atenção é prestada aos mecanismos de aprendizagem colectiva e de geração de factores de inovação, sublinhando, igualmente, alguns equívocos que permanecem nestas matérias.
Por último, são aventadas algumas sugestões para a elaboração de um roteiro de intervenção de medidas de políticas que possam tornar os territórios mais apetrechados para desenvolverem estratégias qualificantes baseadas na diferenciação e na inovação.
A new C15-acetogenin, sagonenyne (20), exhibiting an unusual single tetrahydropyran ring was isolated from an ethyl acetate extract of Laurencia obtusa collected on the Corsican coastline. Its structure was established by detailed NMR spectroscopic analysis, mass spectrometry, and comparison with literature data. Twenty-three known compounds were identified in the same extract by means of column chromatography steps, using a (13)C-NMR computer aided method developed in our laboratory. In addition to sesquiterpenes, which represent the main chemical class of this extract, diterpenes, sterols, and C15-acetogenins were identified. The crude extract was submitted to a cytotoxicity assay and was particularly active against THP-1 cells, a human leukemia monocytic cell line.
Order release is a key component of Workload Control - a production planning and control system that aims at balancing workloads across workstations, while ensuring the timely release of jobs (or orders) to the shop floor in order to meet due dates. Several release methods have been proposed and evaluated in the WLC literature. A major criterion to distinguish between release methods is whether they take the release decision at periodic time intervals or continuously. This paper aims at improving WLC order release by incorporating a starvation avoidance trigger into continuous release. Using simulation, we demonstrate that significant performance improvements in terms of mean tardiness and standard deviation of lateness can be obtained. These results are expected to have important implications for industrial practice and for future research on WLC.
A cultura da nogueira (Juglans regia L.) para exploração do fruto é uma prática de longa data em diversos países do mundo. As características organoléticas da noz que até aos nossos dias estavam na base do interesse comercial do fruto, enquanto elemento da dieta alimentar humana, têm vindo a ser alvo de um reconhecimento crescente nos últimos anos, por força do aumento da capacidade de análise dos constituintes do fruto bem como do conhecimento dos efeitos que estes podem exercer na saúde alimentar do Homem. Contribui ainda a favor da cultura da nogueira a grande diversidade de utilização dos seus produtos além da alimentação humana, designadamente na indústria farmacêutica, no fabrico de corantes, de licores e ainda na indústria da madeira e seus transformados.
The main objective of this article is to provide a comprehensive view of academic studies
that address simultaneously the circular economy and industrial symbiosis, based on bibliometric
data for the years 1900 to 2018. Data are collected in Web of Science using the VOSviewer software.
Bibliometric indicators, network citation, cluster analysis, and density view analysis are used. From
our findings we highlight four clusters in the research, which help to contextualize the literature
review: (a) circular economy: approaches and tools; (b) industrial symbiosis Dynamics; (c) circular
economy: strategies and performance; (d) the efficiency of resources in symbiosis industry. This
study also establishes perspectives for future lines of research and, correspondingly, seeks to
provide a theoretical basis that can serve as a starting point for future studies.
This study aims to fulfil a gap in the literature, delivering a road map to understand the course and nature of the fair value accounting literature, further showing how the 2008–2009 financial crisis affected it. Bibliometric methods analyze 377 documents retrieved from the Web of Science and Scopus databases. Results show a heavy increase in fair value accounting literature starting due to the 2008–2009 financial crisis, further showing a shift from fair value accounting regulations to topics such as fair value measurement, earnings management, value relevance, and banks. Results provide further evidence about relevant themes, showing that topics related to financial crises stay relevant, even during times of growth.
The rainfall intercepted by an isolated olive tree was measured in a traditional olive-grove/ pasture system with a sparse canopy cover. Results from a two-year period of observations are presented. The data are then used to test models of the interception process in this type of agricultural system. Modelling was performed at the single tree level using the sparse-forest version of the Gash analytical model combined with two other methodologies: the wet bulb approach, to estimate the evaporation rate from the wet canopies of individual olive trees, and a newly developed procedure to estimate the canopy structure parameters. Good model performance was achieved at the storm level with model simulations within 1.5% of the observed value, clearly within the expected error of interception loss measurements.

Efficient use of resources is a critical factor in almond crops. Technological solutions can significantly contribute to this purpose. The VeraTech project aims to explore the integration of sensors and cloud-based technologies in almond crops for efficient use of resources and reduction of environmental impact. It also makes available a set of relevant and impactful performance indicators in agricultural activity, which promote productivity gains supported by efficient use of resources. The proposed solution includes a sensor network in the almond crops, the transmission of data and its integration in the cloud, making this data available to be consumed, processed, and presented in the monitoring and alerts dashboard. In the current state of the development, several data are collected by sensors, transmitted over LoRaWAN, integrated using AWS IoT Core, and monitored and analysed through a cloud business analytics service.
After the accidents occurred during the first decade of this millennium, such as the World Trade Center (2001), London (2005) and Madrid (2004), special attention was given to the study of robust structures subjected to different accidental loads. The World Trade Center attack highlighted troublesome weakness in connections, which exhibited poor performance caused by brittle failure. Structural details played a very significant behavioural role when the structure is subjected to impulsive loads [1].
Concerning the behaviour of steel joint, the literature presents several studies on steel connections under both static and cyclic loads [2, 3]; many results of these studies have contributed for improving the current standards, such as the Eurocode 3, part 1-8 [4]. However, only scarce information exists concerning the behaviour of these joints directly loaded by higher loading rates [5].
This paper is devoted to the report of an experimental programme on steel joints under impact loading, in particular to the assessment of T-stub response under tension. The T-stub is used to evaluate the behaviour of the tensile components that are responsible for the deformability of the joint, such as the end plate in bending. Firstly, the paper describes the features of an experimental system developed at the University of Coimbra, to apply high rates of loading; then, it presents the experimental campaign and the corresponding results.
The test apparatus is defined by a rigid reaction frame fixed to a reaction slab and connected to a rigid “flying beam” (HEM 340, S355J2); the impact force is applied in this beam through a pneumatic driven cylinder ( = 125 mm). This “flying beam” consists in a second class lever pivot located at the opposite end of the cylinder location, and the tested specimen is subjected to the dynamic force at the middle of this beam. The pneumatic cylinder was designed to work with a maximum operating pressure of 30 MPa. During the impact tests, force, displacements, accelerations and strains are measured. Because this type of tests occurs in a very short time intervals (hundredths of a second), specific equipment with large sample rate are used.
The experimental programme includes two impact tests on welded T-stubs: i) test T-10-D120-160 - rapidly applied loading of 120 Bar [12 MPa], followed by 160 Bar [16 MPa]; and ii) test T-10-D160 - rapidly applied loading of a single impact equal to 160 Bar [16 MPa]. The results of these tests are compared against reference quasi-static tests [6]. The T-stub geometry is defined by two plates, the flange and the web, both with 10 mm of thickness and welded by means of a continuous 45º fillet.
The flange is bolted through two bolts M20, grade 8.8 fully threaded.

Con el fin de abandonar la idea tradicional de que la observación es objetivo y que, debido a la objetividad de los hechos empíricos es posible establecer una correspondencia con la realidad, la certeza y la verdad si se busca a través de una situación experimental problemática, inserta en un contexto Historia de la Ciencia, para crear un contexto educativo adecuado para la comprensión de la relación de la observación con la teoría que interpreta.
This paper proposes a new methodology for the generation of quadrature amplitude modulation signals, based on all-optical processing from nonlinear interferometric devices. The degradation of the systems performance is numerically analyzed, as a function of operational parameter’s unbalance and physical impairments of the system. The results shows that the probe laser power and the coupling factor of optical couplers are the most sensitive parameters of the proposed format conversion system.
Design/methodology/approach
This study uses bibliometric methods and topic models, specifically latent Dirichlet allocation (LDA) methods to evaluate the nature and course of the tourism crises and disasters scientific literature. Data from 2810 documents were retrieved from the Web of Science database and were used to perform the analysis.
Purpose
The COVID-19 pandemic caused unprecedented global turmoil and a halt on international tourism. This study aims to evaluate the scientific literature about tourism crisis and disasters and depict how this research stream evolved in the face of economic, security, health, environmental, or trust crises, further providing insights about a research agenda on this stream.
Findings
Results show an increase of tourism crises and disasters scientific literature departing from 2010, and a surge in 2020 and 2021 due to the COVID-19 pandemic. Furthermore, themes such as tourism competitiveness, tourism demand, crisis management, perceived risk, natural disasters, and destination recovery are among the most relevant themes in the research line, showing that the effect of economic and financial crises on tourism industry, sustainable tourism, and tourism demand are set to be among the most relevant in the upcoming years.
Implications
This study fills a void in tourism literature by providing a roadmap to understand the past, present, and future of the tourism crises and disasters research line and the avenues for future research in this field, including methods, in the period post COVID-19.
Originality/value
Previous studies on tourism crises and disasters were focused on literature review and on the relationship between crises and disasters and the tourism industry. This study uses a set of methods unused before in the research stream, namely a combination of bibliometric methods and latent Dirichlet allocation (LDA) methods, to provide a road map for the present state-of-the-art of tourism crises and disasters research and promising future research lines.
In elderly people, double or multitasking (cognitive and motor) are severely impaired, associated with reduced cognitive function and loss of automatic capacity of the motor and musculoskeletal system.
The activation of brain areas of cognitive control during the task demonstrates the relationship of cognitive functions with motor function, so that the ability of the dual task has a great impact on the performance of daily activities.
However, there is no consensus on measures to evaluate multiple tasks.
Methods
An experimental protocol was tested four times over 8 months in a sample of 126 eldelly (60-98 years old 78.98 ± 8.34) to evaluate functional performance reported in walking, cognition and coordination in double and multiple tasks , along a path (6mx0.4m). We test eight different tasks conjugations of a) walking straight, b) counting back, c) coordinating the upper limbs and d) overcoming the obstacle. We also used MMSE, TUG and TUG-Cognitive and an IADL scale. The score of the experimental protocol is done by counting errors.
Results
Time differences between TUG-Cognitive and TUG are used to compare several task conjugations of the protocol.
Statistically significant correlation with the differences between TUG-Cognitive time and TUG and MMSE was found to a dual task (walking and counting back) na to a multiple task (walking in a straight line with coordination of the upper limb and counting)
Conclusions
The ability of older people to perform dual and multi-tasks can be measure with a easy protocol including task as walkink, count backward and upper limb coordination.
The concept of land units refers to coherent spatial areas that are characterized by a certain degree of homogeneity concerning certain properties like geology, soils, and climate. The Land use mosaic corresponds to a circumstantial layer that represents the present state of the landscape depicting the present factors of resource allocation. Nevertheless, the stable potential layer is related to the stable characteristics of each site and allows the identification of use constraints or potentials. In this study we use a methodology based in the land unit concept to define a stable potential layer at a regional level. Therefore, 26 land units were delimited for the Beira Baixa region. Those units resulted from the combination of geomorphology, soil parent material and bioclimatic influence. For each land unit representative samples were characterized in terms of its land use mosaic attributes. For that purpose, selected landscape metrics were calculated, quantifying the land use mosaic geometrical characteristics, namely: Shannon’s Diversity Index, Edge Density, Mean Patch Size and Number of Patches. The existing land use types were also quantified. Finally, a cluster analysis was performed to define groups of samples representing the land units that have similar land use mosaic types. The validation of the previously defined land units confirmed the reliability of the proposed methodology, with most of the land units strongly influencing the land use mosaic. This relationship is stronger in the land units that occupy a higher extension in the region, mainly soils rich or very rich in silica under the influence of a Mesomediterranean subhumid bioclimate.

The understanding of the relationship between communities and the landscape mosaic, shaped by the different land uses, is important for an integrated management of the habitats. The landscape indexes might be a useful tool for landscape analysis as well as a landscape describer.
The scope of this work is to check the reliability of some landscape indexes by using a multi scale approach, verifying how the nesting passeriformes birds communities are related with the landscape structure of the montado .
Data was obtained from bird and vegetation census and form a spatial analysis applied on a land use map. Multivariate statistics analysis were performed and interpreted accordingly with the species ecological requirements in order to detect the more reliable scale for landscape indexes.
By exploring the concept of image curation, this article presents a proposal for the applicability of image curation in the development of Projects of Design, exploring the role of visual curation as a contribution to the development of interfaces between academia and business. Due to the amount of data present in digital culture, content curation is an increasingly important activity in project development. In higher-education design formation, image curation allows safeguarding the project literacy on the one hand, through the definition and clarification of an organization of visual elements and defining a basis for dialogue on the projective possibilities. The proposed strategy for visual curation offers the possibility of being applied as a basis of dialogue with external stakeholders. Moreover, thus, in a context of learning in design, enabling another bridge between the Academy and the corporate fabric.

The construction sector is one of the major contributors for the increase of pollution and environmental degradation. The uncontrolled increase on the consumption of natural resources, the way they are used and the high emissions they arise, are impelling the study and implementation of policies and procedures which ensure a sustainable future for construction and for the sustainability of the planet. The objective of this paper is to present the work devel-oped in order to assess and optimize the sustainability of a residential building at the design stage, through the application of a sustainability assessment tool, SBToolPT-H. A first evaluation was done, when conventional solutions were adopted. After this, a proposal was developed with several improvements in order to create a sustainable building that corresponds to the Portuguese best practices. This case study was developed taking into account the twenty-five sus-tainability indicators of the SBToolPT-H assessment system. Additionally, dynamic thermal simulation was used in order to support the optimization of the thermal performance and the indoor thermal comfort.

The layout of the factories in the apparel industry has several processing stations that are grouped in sections that have to do with a particular task (ex. trousers stitch). This together with high levels of production capacity demands the implementation of automatic monitoring systems that allow some sort of feedback related with the production progress of those stations.
This paper describes a system that is being developed at Escola Superior de Tecnologia de Castelo Branco, which is part of the Instituto Politécnico de Castelo Branco. It consists of a prototype for a real time data pick up system, using the Controller Area Network (CAN) [1] bus. The aimed objective is to collect the data contained in bar code labels that are coupled to cloths pieces in an apparel factory during the production process. Those labels have useful information to the production stage (ID number of the piece), and accompany each apparel piece. This system is part of a more global system that will allow the production management using a wed platform linking the commercial, production scheduling, manufacturing control and customer/seller stages.
Reducing the gap between Software Engineering education and the needs in the software industry is a goal for Academia. Advancement in terms of cutting-edge technical skills and good soft skills preparation is the desired goal to shorten the onboarding in the labour market. Generally, in computer science or computer engineering courses, separate subjects exist to teach requirements engineering, analysis and design, coding, or validation. However, integrating all these phases normally requires experience in developing a complete project. The approach presented in this paper has involved the staff of a software company in collaboration with the staff of an academic Institution and resulted in a student's involvement in a full-stack software development project. The student was involved in an agile team composed of teachers and Information Technology (IT) professionals. Scrum framework was followed, and the product was developed using a low-code development platform. Results show that this agile and full stack approach allows students to develop cutting-edge technical and non- technical skills. The paper presents the approach, the achieved results, some lessons learned and some guidelines for the future.

It has been observed, since the 2014s, the emergence of brand creation and management models that contribute to the sustainability of entities, organizations, territories and businesses. Each brand model proposal results from the knowledge, perspective and vision of the respective authors, in the search for answers to complex problems, not always similar. Brand sustainability depends on the experience it represents for stakeholders. Both from the perspective of commercial brands and for Place Branding, the models seem to have common visions, with their advantages and limitations. Brand models are compared from the perspective of their definition, creation, design and management. The non-interventionist methodology based on the descriptive case study, allowed the identification of the essential vectors to be considered in a brand model or in a brand creation process, specifically in Place Branding.

Over the years some medical studies have tried to better understand the internal
behavior of human beings. Many researchers in this domain have been striving to find
relationships between intra-vaginal temperature and certain female health conditions, such
as ovulation and fertile period since woman’s intra-vaginal temperature is one of the body
parameters most preferred in such studies. However, due to lack of a appropriate
technology, medical research devoted to studying correlations of such body parameters
with certain womans’ body phenomena could not obtain better results. This article presents
the design and implementation of a novel intra-body sensor for acquisition and monitoring
of intra-vaginal temperatures. This novel intra-body sensor provides data collection that is
used for studying the relation between temperature variations and female health conditions,
such as anticipation and monitoring of the ovulation period, detection of pregnancy
contractions, preterm labor prevention, etc.. The motivation for this work focuses on the
development of this new intra-body sensor that will represent a major step in medical
technology. The novel sensor was tested and validated on hospitalized women as well as
normal healthy women. Finally our medical team has attested to the accuracy, usability and
performance of this novel intra-body sensor.

This project was carried out at a company in the electric mobility sector, which manufactures chargers for electric vehicles, specifically in the wiring section. The main objective of the developed work was to improve the production processes in order to enhance responsiveness to the growing demand. After analyzing the processes in the section, the objectives were outlined to enable the improvement of some practices in the production department, such as the ones related to the organization of the raw material supermarket, as well as the calculation of the wiring consumption by chargers, and the implementation of a production control system. After the improvement actions were implemented, it was possible to observe a 14,9% reduction in the changeover process of the cable cutting process; weekly wiring consumptions were estimated, and procedures were defined to generate orders of raw material and supply to the workstation, which led to the elimination of stock shortages. In addition, worker autonomy increased and production downtime was reduced.
Bedded or lying-people pressure-map datasets can be used to identify patients’ in-bed postures and can be very useful in numerous healthcare applications. However, the construction of these datasets is not always easy, and many researchers often resort to existing datasets to carry out their experiments and validate their solutions. This systematic review aimed to identify and characterise pressure-map datasets on lying-people- or bedded-people positions. We used a systematic approach to select nine studies that were thoroughly reviewed and summarised them considering methods of data collection, fields considered in the datasets, and results or their uses after collection. As a result of the review, six research questions were answered that allowed a characterisation of existing datasets regarding of the types of data included, number and types of poses considered, participant characteristics and size of the dataset, and information on how the datasets were built. This study might represent an important basis for academics and researchers to understand the information collected in each pressure-map dataset, the possible uses of such datasets, or methods to build new datasets.
Vehicular networks are emerging as a promising technology that enables reliable and low-cost solutions for intelligent transport systems (ITSs), mainly due to their enormous potential to be considered for multiple purposes and scenarios. These networks are characterized by unique and challenging features such as packet fragmentation, low node density, short contact duration, and network disruption. These features may result in the absence of a path between the source and destination nodes, which is one of the most challenging issues faced by this type of network. To overcome some of these problems, it is necessary to provide vehicular networks with sophisticated tools or methodologies to implement monitoring and management operations. However, designing efficient solutions for this type of network is not an easy task due to its particular characteristics. This paper elaborates on a comprehensive survey focusing on promising proposals to deal with monitoring and management functionalities in vehicular networks. This work aims not only to present the state of the art on monitoring and management solutions but also to analyze their benefits and drawbacks, identify open issues, and provide guidelines for further contributions.

The purpose of this study is to add our efforts to those of researchers who have been concerned with a better understanding of the state of the art in Science Education Research (SER). The study focuses on the nature and evolution of the main SER lines, e.g. ,what researchers actually do when they enter the research community in order to develop Science Education. We believe that the exercise may help to reinforce the identity of SER, to gain a better knowledge of the field, and to make some educational proposals for mid-term priorities, in short, to foster the advance of Science Education knowledge. The corpus of the study was formed by the 152 most influential SER papers published from 1993 to 2002. Two criteria were used to select the papers: they had to be published in three of the most important international research journals, plus a criterion based on the citation index. Content analysis of the corpus indicates that Concept-Learning-oriented studies tend to make way for studies emphasising the role of the Philosophy of Science and also for multidisciplinary approaches such as STS. Thoughts for the development of the research field are put forward.
Fruit detection is crucial for yield estimation and fruit picking system performance. Many state-of-the-art methods for fruit detection use convolutional neural networks (CNNs). This paper presents the results for peach detection by applying a faster R-CNN framework in images captured from an outdoor orchard. Although this method has been used in other studies to detect fruits, there is no research on peaches. Since the fruit colors, sizes, shapes, tree branches, fruit bunches, and distributions in trees are particular, the development of a fruit detection procedure is specific. The results show great potential in using this method to detect this type of fruit. A detection accuracy of 0.90 using the metric average precision (AP) was achieved for fruit detection. Precision agriculture applications, such as deep neural networks (DNNs), as proposed in this paper, can help to mitigate climate change, due to horticultural activities by accurate product prediction, leading to improved resource management (e.g., irrigation water, nutrients, herbicides, pesticides), and helping to reduce food loss and waste via improved agricultural activity scheduling.

Industrial and agricultural activities heavily constrain soil quality. Potentially Toxic Elements (PTEs) are a threat to public health and the environment alike. In this regard, the identification of areas that require remediation is crucial. In the herein research a geochemical dataset (230 samples) comprising 14 elements (Cu, Pb, Zn, Ag, Ni, Mn, Fe, As, Cd, V, Cr, Ti, Al and S) was gathered throughout eight different zones distinguished by their main activity, namely, recreational, agriculture/livestock and heavy industry in the Avilés Estuary (North of Spain). Then a stratified systematic sampling method was used at short, medium, and long distances from each zone to obtain a representative picture of the total variability of the selected attributes. The information was then combined in four risk classes (Low, Moderate, High, Remediation) following reference values from several sediment quality guidelines (SQGs). A Bayesian analysis, inferred for each zone, allowed the characterization of PTEs correlations, the unsupervised learning network technique proving to be the best fit. Based on the Bayesian network structure obtained, Pb, As and Mn were selected as key contamination parameters. For these 3 elements, the conditional probability obtained was allocated to each observed point, and a simple, direct index (Bayesian Risk Index-BRI) was constructed as a linear rating of the pre-defined risk classes weighted by the previously obtained probability. Finally, the BRI underwent geostatistical modeling. One hundred Sequential Gaussian Simulations (SGS) were computed. The Mean Image and the Standard Deviation maps were obtained, allowing the definition of High/Low risk clusters (Local G clustering) and the computation of spatial uncertainty. High-risk clusters are mainly distributed within the area with the highest altitude (agriculture/livestock) showing an associated low spatial uncertainty, clearly indicating the need for remediation. Atmospheric emissions, mainly derived from the metallurgical industry, contribute to soil contamination by PTEs.
Students have developed a different set of activities and opportunities, resulting from interactions with
technology and environments rich in new and old media. This can provide great advantages in many
areas, such as the ability to use information technology and the ability to work collaboratively. But, on
the one hand, this may also create a discontinuity between their expectations and the work
environment they will find in universities. To avoid this discontinuity, organizations must find alternative
methods to traditional ones. On the other hand, universities should foster interactivity and collaborative
work. For this, there must be a remodeling of existing spaces in organizations to enhance these
characteristics. It is thus evident a necessary remodeling of the spaces of motivated learning, both by
technological needs and by students' needs. A Learning Space project must be aligned with the
strategy of the Institution. The face of an Institution will be characterized by the Spaces of Learning
that it offers. The importance of the introduction Information and Communication Technologies in the
learning/teaching process it’s an important point in the creation of Learning Environments, but just by
itself it does not bring significant changes. In this context, we propose a Model of the Learning Space
Organization based on identification of the factors considered essential for Building High Quality
Learning Environments. We assume that Design changes, Cultural changes along with Rich spaces
Technology and New Planning spaces lead to the construction of High Quality Learning Environments.

Background
Both physical inactivity and sedentary behavior are considered modifiable risk factors for chronic diseases and all-cause mortality. Adult office-workers spend most of their working day in sedentary behaviors, so they are particularly at high risk of developed chronic diseases (e.g., cardiovascular diseases, metabolic disorders like diabetes mellitus, . . .). It seems important to promote behavioral changes that could prevent or delay metabolic disease development. Evidence supports the use of exercise programs, however, to date there are several knowledge gaps and inconsistencies in the literature regarding the effects of Combined Training (i.e., aerobic plus resistance training) in sedentary healthy adults. This paper outlines an RCT designed to evaluate the effects of a 16-week combined training program on biochemical and immune markers of metabolic disease, lung function, salivary stress hormones and subjective quality of life (primary outcomes), as well as on body composition and physical fitness (secondary outcomes) in sedentary middle-aged office-workers. Furthermore, we aimed to assess the associations between the changes promoted by the exercise program and the different variables studied.
Methods and design
This is a single-blinded two-arm RCT with parallel groups. A minimum of healthy 40 officeworkers aged 40–64 years will be recruited to engage in a 16-week intervention study. After baseline assessments, participants will be randomized to one of the two groups: (1) combined training group or (2) control group. Baseline assessments will be repeated after 8 weeks of intervention (mid-testing) and upon completion of the intervention (post-testing).
Discussion
This RCT involves a multi-disciplinary approach and seems to be a relevant contribution to understanding the potential role of combined training in improving the metabolic profile, lung function, stress, and quality of life in adults. The results can provide important insights for clinical recommendations and for the optimization of strategies to prevent metabolic disorders in adults with sedentary jobs.

Human diversity faces several challenges, as there are many people in situations of vulnerability due to personal and environmental factors. Vulnerable populations can experience physical, psychological, and social problems. Those include people who face great precariousness in their life and find themselves in a situation of effective vulnerability. These people need a prompt, effective and a scientific evidence-based response to overcome barriers thrown at them. This book compiles a set of focused evidence chapters to raise awareness on the particular conditions of special populations, invoking assessment and intervention to promote better life conditions.
In the first chapter we can find an issue that affects contemporary society, the ageing population. Although living longer is an unquestionable gain, the truth is that increasing average life expectancy inevitably entails the onset of dementia, urging the need to slow its progression and minimize its impact. It presents scientifically based physical activity to combat the cognitive decline and extend the years of life with quality.
Chapter 2 raises awareness on people with brain damage with altered consciousness. The uncertainty on the patient’s state of conscience leads to doubts in the course of action to follow in terms of treatment or prolongation of life. Correct assessment plays a vital role to foster best decisions and directed interventions on the patient’s best interest. Situations of misdiagnosis and consequently unachieved interventions are frequent and must be improved through extended and evidence-based approaches. People with special needs are addressed in the third chapter. We are in a global world where borders fade and anyone can pursue employment and better life outside his/her country. It may seem simple, but there are persons with constraints that cannot fulfil their needs. Not using a common language can prevent social and employment relations. Exclusion is aggravated when learning a language hampered by a functional limitation. Sensory, motor
and cognitive disabilities can hinder a truthful inclusion in modern society. EN-ABILITIES is a European project that aims to enable English autonomous learning by people with diverse needs, sustained on a universal design for learning approach.
The fourth chapter focuses on the performance of activities of daily living of children with disabilities. What for many is considered acquired, for others it seems to be a difficult task. Those inattentive, may not realize the impact of having great difficulties, or not being able, to perform everyday tasks can have in the life of a child with functional limitations. Depending on others for several tasks, having reduced options for activities and encountering mobility barriers is a crucial factor for those who experience great difficulties. Knowing this and other issues can structure routines that facilitate their inclusion in the different contexts in which these children are inserted. Autism Spectrum Disorders are discussed on the fifth chapter. It has been found that children with ASD experience difficulties processing, integrating and responding to sensory stimuli. Consequently, behaviours associated with difficulty processing and integrating sensory information create social isolation for children and their families, restrict participation in daily living activities and impact social engagement. What for some can be misbehaviour is in fact a maladaptive response to the environment and must be carefully addressed to minimize and overcome sensory processing dysfunctions. Specialized interventions such as occupational therapy using sensory integration are in order to help children with ASD respond more
adequately to environmental stimuli. Diabetes, referred in chapter six, is a modern world disease. Although it may be congenital, it also emerges from modern life style and eating habits. Aetiology aside, it can be seen that it can lead to serious problems with loss of independence and drastic reduction of quality of life. The adoption of a strategy to prevent the onset and progression of the disease are imperative. However, when it is already installed, its effects must be minimized. The combination of the intervention of different professionals seems like the procedure to adopt for an optimized approach.
Chapter seven goes through Celiac disease an increasingly visible condition, with frequent identification of more cases. The ordinary citizen is not aware of the difficulties that people suffering from this disease suffer. In catering and collective food services, mistakes that can harm a vulnerable person are frequent. It is important to raise awareness of the effects of the disease, in particular those that can make a difference in the lives of these people, avoiding things as simple as cross-contamination in food distribution, storage and handling, without ever forgetting the need for research and innovation for normalizing the diet of these people.
Animal Assisted Therapy and Developmental Disorders come to us in chapter eight. In it we can read how therapy with animals can assist in the promotion of skills, health-related issues and well-being of persons with developmental disorder. The overview presented shows the array of conditions that can benefit of this type of interventions. The basis of the intervention is the arise of a relationship that liberates the person with developmental disabilities, promoting positive emotional responses that influence neurobiological components and enhances performance in diverse areas, independent functioning, social participation and quality of life of those which are confronted with limitations due to disorders in their development.
Early in this book, physical activity was mentioned as a preventive and therapeutic intervention for people with diverse conditions. Chapter nine addresses again physical activity, but this time in people with disabilities. Due to their functional constraints, people with disabilities tend to perform less, or not to perform, physical activity that would greatly benefit them in a multidimensional way. It reveals the need to identify the physical activity determinants in order to contribute to conceptual changes, new interventions and policies that increase the levels of physical activity on this population and, consequently, further advance in their full social inclusion.
The final chapter, chapter 10, deepens the theme of physical activity in children with disabilities. It’s well known regular physical activity has a positive impact in health and lifestyle, contributing for functionality and quality of life. It is important to create opportunities for physical activity. In this context, school sports appear as a first line of intervention. Inclusion is a trend that must be completely fulfilled. Legislation protects the rights of functional diverse students and obliges to their inclusion in school activities, of which school sports cannot be an exception. Although it may seem less compelling to mandatorily engage in physical exercise, the truth is that if it is not enforced, it will probably never be performed by those who need it. For the foregoing, this book assumes as essential when the theme are populations in situations of vulnerability. Academics, technicians, and the general population here have a source for drinking knowledge shed by scientists and based on rigorous scientific evidence.
El envejecimiento de la población es un hecho cada vez más observable en varios países desarrollados, como Portugal. Esta fase de la vida conduce a pérdidas biológicas y, a veces, a otros problemas psíquicos y sociales, lo que conduce a una disminución de la calidad de vida en esta edad. El presente estudio tuvo como objetivo verificar si los mayores, practicantes de un programa regular de actividad física formal tienen una mejor percepción de su calidad de vida que los mayores, no practicantes. La muestra consistió en 64 ancianos (n = 64), residentes en Proença-a-Nova, divididos en dos grupos, uno que designamos a grupo de practicantes con 32 individuos que participan en los programas de hidrogimnasia y gimnasia sénior, y otro con 32 elementos designados por grupo de no practicantes, que incluían individuos
que no practicaban actividad física formal. La calidad de vida percibida se midió utilizando el cuestionario MOS SF-36v2. Los resultados revelaron que la percepción de la calidad de vida tiende a ser mayor en los practicantes de actividad física, pero solo presenta diferencias estadísticamente significativas en las dimensiones de la función física, la función social y en el elemento de cambio en la salud, presentando valores más altos para el grupo de practicantes.
The spread of multidrug-resistant (MDR) Klebsiella pneumoniae in the nosocomial setting represents a big challenge to infection control teams. We have recently developed a simple spectroscopic-based method with excellent accuracy, turnaround time and cost-effectiveness (Rodrigues et al. mSystems 2020) for bacterial typing. Here, we applied our method in a real clinical context to support early identification of an outbreak involving KPC-3-producing K. pneumoniae ST147 isolates. Our results further support that attenuated total reflectance Fourier transform infrared (FT-IR) spectroscopy can provide enough information to support early and adequate infection control measures and therapeutic choices in the context of nosocomial outbreaks and hospital surveillance.
The emergence of multidrug-resistant bacteria has prompted the development of alternative
therapies, including the use of natural products with antibacterial properties. The antibacterial
properties of Zantaz honey produced in the Moroccan Atlas Mountains against Escherichia coli,
Pseudomonas aeruginosa, and Staphylococcus aureus was evaluated and analyzed using chemometric
tools. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC)
against S. aureus were the lowest (112.5 ± 54.5 mg/mL), revealing that this species was most sensitive
to Zantaz honey. P. aeruginosa showed an intermediate sensitivity (MIC= 118.75 ± 51.9 mg/mL), while
E. coli was the most resistant to treatment (MIC = 175 ± 61.2 mg/mL). Content of monosaccharides,
certain minerals, and phenolic compounds correlated with antibacterial activity (p < 0.05). Principal
component analysis of physicochemical characteristics and antibacterial activity indicated that the
parameters most associated with antibacterial activity were color, acidity, and content of melanoidins,
fructose, epicatechin, methyl syringate, 4-coumaric acid, and 3-coumaric acid.
