Authors: Talahua Jonathan S. , Buele Jorge , Calvopiña P. , Varela-Aldás José
Published: June 2021

In the face of the COVID-19 pandemic, the World Health Organization (WHO) declared the use of a face mask as a mandatory biosafety measure. This has caused problems in current facial recognition systems, motivating the development of this research. This manuscript describes the development of a system for recognizing people, even when they are using a face mask, from photographs. A classification model based on the MobileNetV2 architecture and the OpenCv’s face detector is used. Thus, using these stages, it can be identified where the face is and it can be determined whether or not it is wearing a face mask. The FaceNet model is used as a feature extractor and a feedforward multilayer perceptron to perform facial recognition. For training the facial recognition models, a set of observations made up of 13,359 images is generated; 52.9% images with a face mask and 47.1% images without a face mask. The experimental results show that there is an accuracy of 99.65% in determining whether a person is wearing a mask or not. An accuracy of 99.52% is achieved in the facial recognition of 10 people with masks, while for facial recognition without masks, an accuracy of 99.96% is obtained.

Published: June 2021

Recently, in line with the increased attention paid to cultural tourism in general and to religious tourism in particular, researchers and practitioners have become increasingly interested in the analysis of various aspects related to cultural heritage in order to capitalize on its value by means of its interpretation, thus providing beneficial effects both for tourists and for tourism’s sustainable development. The aim of this research is to analyze the extent to which the methods of interpretation of the religious cultural heritage: guiding tours, quality reception, and relic worship influence the satisfaction of tourists participating in the “Saint Parascheva” pilgrimage, held annually by the Metropolitan Cathedral in Iasi. The data were collected by means of a survey (N = 932) and the information was processed by using the SPSS version 25 program. Our results indicate the significant influence that the potential to worship relics has on pilgrims’ satisfaction compared to other interpretation methods, such as the relationship with the Cathedral’s staff or the possibility of participating in guided tours. Pilgrims’ satisfaction is also perceived differently depending on certain aspects of their socio-demographic profile, i.e., their age and the perceived faith level. This study is relevant for researchers, managers, and students interested in the field of cultural heritage interpretation in genera, and in the field of religious heritage in particular, and could significantly contribute to improving pilgrims’ satisfaction as well as cultural heritage preservation.
Impact of Gender and Expatriation Choice on Career Paths in Supply Chain Management: Evidence from Master of Science Graduates
Authors: Ruel Salomée , Jaegler Anicia
Published: June 2021

Zinn et al. (2018) and Esper et al. (2020) call for more research on gender diversity in Supply Chain Management, and our study responds to that call. We analyze the career path of 1081 international graduates from a higher degree program in Supply Chain Management from 2000 to 2017 to assess the impact of gender and expatriation choice on hierarchical progression. We explore two variables that may affect graduates’ career paths, namely, their gender and their expatriation choices, and compare their relative importance. Our analysis shows that there were, on average, 33.5% women recruited in the MSc and that this has not significantly changed over the years. It also shows that gender significantly influences the number of years spent at each level in the career hierarchy and the level reached. Regarding expatriation choice, this variable has some significant impacts on career progression. Finally, statistics indicate that gender has a far greater influence on career progression than expatriation choice. Overall, this study proves the difficulties for women in enjoying the same career progression as men in the field of Supply Chain Management.

Expert Panel, Preventive Maintenance of Heritage Buildings and Fuzzy Logic System: An Application in Valdivia, Chile
Authors: Carpio Manuel , Prieto Andrés J.
Published: June 2021

The maintenance of buildings is a highly complex decision process, which is generally due to professional experts having to consider several arduous evaluations, especially regarding uncertainty related to why, when and how to intervene. This study concerns the analysis of the uncertainty associated with professional experts’ surveys during the decision-making process during building maintenance. For this purpose, a case study of a timber-structure building was examined. An expert panel of 66 professionals with expertise in construction engineering carried out a systematic and automated evaluation. This kind of digital method is capable of managing the uncertainty associated with the evaluation processes by different specialists. Experts can evaluate various nuances and approximations in the model’s input parameters. The fuzzy model helps to harmonize the results since minor variations in the evaluation of the input parameters do not generate a large dispersion over the model’s output variable. The novelty of this study concerns the application of a digital methodology based on a fuzzy logic model to assist a professional expert panel in different areas—architecture, engineering and construction. This study is oriented through an artificial intelligence based method applied by specialists to set intervention priorities, support maintenance management of the examined building and minimise human error during data collection and uncertainty related to making decisions. The lessons learned from the results obtained in this study promote the use of this kind of digital tool to manage the uncertainty associated with in-situ visual inspections.
Audit Quality under Influences of Audit Firm and Auditee Characteristics: Evidence from the Romanian Regulated Market
Authors: Carp Mihai , Istrate Costel
Published: June 2021

We have estimated the impact of some characteristics of the auditors and of the audited companies on audit quality for the Romanian listed firms (943 observations for the 2007–2019 period), using as a proxy for the audit quality the level of discretionary accruals, measured following the Jones (1991) model, and the accruals quality, estimated through the Dechow and Dichey (2002) model. These dependent variables have been related to variables that reflect both the characteristics of the audit firm (for example, Big 4 membership) and the characteristics of the audited firms (dimension, financial leverage, accounting standards applied, growth and profitability). Our results show that the auditor’s Big 4 membership contributes to an increase in discretionary accruals, decreasing the quality of the audit. The transition to IFRS did not have a significant influence on the quality of the audit. The audit opinion may have an effect on the discretionary accruals and the accruals quality in the sense that a modified opinion leads to an increase in the quality of the audit in the following financial year(s).
Stakeholders’ Perceptions of the Possible Energy Sustainability Solutions in the Hotels of the Canary Islands
Authors: Lorente de las Casas Andrés , Mirkova Ivelina , Ramos-Real Francisco J.
Published: June 2021

Energy production and consumption represent the most significant sources of CO2 emissions in the world. An isolated island scenario such as the case of the Canary Islands, where dependence on fossil fuels is almost complete needs an effective integrative strategy for energy efficiency in order to reduce the carbon footprint. The objective of our work is to propose an effective design for an integrative and sustainable energy transition strategy in the hotel sector of the Islands. To achieve this, we implement a qualitative/quantitative technique called Q methodology. Our study was conducted with a carefully selected group of 31 experts from diverse areas related to the energy sector who were asked to rank-order their degree of agreement or disagreement with 30 key energy discourses (statements). The results of our analysis identify four profiles of stakeholders’ mindsets: the “Low-carbon”, the “Techies”, the “Skeptics”, and the “Trusting”. A well-defined integrative strategy could be identified which includes self-consumption using renewable energies, simplification of the administrative procedures, and promotion of the use of heat pumps, among others. A further interesting consensus result among all four groups reveals experts’ uncertainty regarding the post-COVID-19 reality.

Published: June 2021

In this research, we planned and conducted estimations for developing a pilot-scale Clean Development Mechanism (CDM) project for group plant activities in the Vietnam electricity/energy sector. The overall aim of this paper is to assess the power generation potential of rice husk power plants in the Mekong Delta. We intend to set up a rice husk energy balance flowchart for the whole Mekong River Delta in the year 2021 and suggest policies that can be used for the power generation of unused rice husk, to avoid having them pollute rivers and canals. We put forward a safe and environmentally friendly solution to thoroughly minimize the current serious pollution of rivers and canals in the Mekong River Delta caused by the increasing quantity of unused rice husk. The results of this paper are based on the estimation of electricity potential of a group of rice husk power development plants in the Mekong River Delta with a capacity of 11 MW per plant, including carbon dioxide emission reductions (CERs) and CER credits, along with estimations of their economic criteria (NPV, B/C, IRR), both W/CDM and W/O CDM.
The City as an Experimental Environment: The Identification, Selection, and Activation of Distributed Knowledge in Regional Open Innovation Ecosystems
Authors: Robaeyst Ben , Baccarne Bastiaan , Duthoo Wout , Schuurman Dimitri
Published: June 2021

Over the past decade, open innovation (OI) literature has extended its scope beyond strictly economic contexts to the context of societal value creation. This has given rise to the notion of (local) distributed knowledge as a driver for sustainable innovation and has highlighted the importance of multi-stakeholder collaborations in new product development (NPD) processes to develop new ICT systems for complex urban issues. Several studies have discussed sustainable stakeholder ecosystem architectures for such collaborations. However, little is known about stakeholder identification and selection processes for collaborations in the urban environment. By combining action research with a case study design, this paper studies the nature of contextualized interactions between knowledge actors in the ecosystem and the processes of attraction, identification, selection, and activation of stakeholders in an urban living lab (ULL). These insights converge in the development of a ‘stakeholder acupuncture framework’, which structures mechanisms and practices within dynamic collaboration ecosystems and defines key boundary conditions for such open-ended ecosystems.
The Reverse Gender Gap in Volunteer Activities: Does Culture Matter?
Authors: Bellido Héctor , Marcén Miriam , Morales Marina
Published: June 2021

Women take on 57% (men: 43%) of all volunteering globally (UN 2018). In this paper, we follow an epidemiological approach to explore the possible role of culture in determining this reverse gender gap in the time devoted to volunteer activities. To that end, we merge data from the American Time Use Survey for the years 2006–2019 and the Gender Gap Index (GGI) of the World Economic Forum 2021. We use a sample of early-arrival first- and second-generation immigrants who live in the United States. Our empirical approach rests on the fact that all these individuals have grown up under the same host country’s labor market, regulations, laws, and institutions but differ in their cultural heritage. Thus, in this setting, gender discrepancies in the time devoted to volunteer activities can be interpreted as the effect of culture. We find that more gender-equal norms in the country of origin are associated with women devoting less time to volunteer activities relative to men. We further analyze the channels shaping the culture from the country of ancestry and the existence of horizontal (within-communities) transmission of culture. Our results are robust to the use of different subsamples and to the inclusion of demographic and socio-economic controls.

Published: June 2021

This paper examines the athletes’ perception of their coaches according to the role of starter or substitute in the final phase of the season. The variables analyzed were: leadership style, perceived justice, competence, and support for basic psychological needs. A longitudinal study was developed, evaluating the participants at two different stages: the end of the season and seven weeks before. A total of 112 football and handball players participated in this study, 78 completing the questionnaire at the two waves. The final sample comprised 51 starters (80.39% males) and 27 substitutes (70.37% males) who evaluated their coaches’ leadership, competence, and support of the players’ psychological needs. The interaction moment of measurement (seven weeks before the end of the season vs. end of the season) * group (starters vs. substitutes) was statistically significant for the variables authentic leadership, perceived justice, and the basic psychological need of competence. Post hoc analyses revealed a significant decline in the perception of authentic leadership from coaches, perceived justice, and support of the psychological need of competence at the end of the season only in those in a starter position, with no change observed in the substitutes group. The findings show that the perceptions of coaches among starting players deteriorates significantly in the final phase of the season, while those among substitutes remain unaffected.
Decisions by Key Office Building Stakeholders to Build or Retrofit Green in Toronto’s Urban Core
Authors: Ensign Prescott , Roy Shawn , Brzustowski Tom
Published: June 2021

The environmental impact of greenhouse gas emissions from buildings—especially in global cities such as Toronto—is well documented. Green mitigation of new and existing buildings has also been researched. Few studies, however, have focused on the decision to build or retrofit green. Are key stakeholders in Toronto’s office building sector aligning their decisions to achieve sustainable environmental goals? Do they support LEED certification regardless of the impact on market valuation? Are tenants willing to pay higher rents in LEED office buildings? The study first obtained data on 16 LEED and 52 conventional buildings to determine if LEED certification has a significant impact on net asking rent. Pearson correlation and linear regression analysis did not find LEED certification to be statistically significant in explaining the variance in net asking rent (market value). The second stage included interviews with senior executives engaged in Toronto’s office building sector. The expert informtabants were asked to assess if financial drivers are the deciding factor in decisions to pursue LEED certification. They concurred that LEED certification is not the primary driver. It is a combination of numerous factors that overall have an impact on a firm’s financial bottom line.
Intergenerational Differences in Family Business Management and Their Influence on Business Profitability
Authors: Moreno-Gené Jordi , Gallizo José Luis
Published: June 2021

The generational change in the family business opens up expectations of strategies such as sustainability, professionalisation and internationalisation. Yet, there are gaps in current literature which fail to explain whether there are benefits in such strategies according to their management, their generational status, and their effects on performance. This paper compared first with second and later generation companies through the relevant characteristics. A regression analysis was applied to a sample that was identified by the Spanish Family Business Institute with information on growth strategy, corporate governance, professionalisation, and ownership, that is supported by financial data for the period of 2016–2020. The results showed that, although the differences in terms of profitability were small between generations, there were significant differences in management that affected performance. Growth tended to be lower in the second and subsequent generations, which also h a greater tendency to internationalise, being motivated by the professionalisation of management. Previous works in the literature have analysed differences in profitability between generations, however the analysis in this present work investigated the origin of these differences. The results showed disparities in management that allowed for the obtaining of different profitability indices, and therefore are of practical importance in the management of the internationalisation, growth, and sustainability of the family business in the face of intergenerational succession.
Universal Approach for DEM Parameters Calibration of Bulk Materials
Authors: Boikov Aleksei , Savelev Roman , Payor Vladimir , Potapov Alexander
Published: June 2021

DEM parameters calibration is the most important step in preparing a DEM model. At the same time, the lack of a universal approach to DEM parameters calibration complicates this process. The paper presents the author’s approach to creating a universal calibration approach based on the physical meaning of the friction coefficients and conducting symmetrical experiments at full scale and in a simulation, as well as the implementation of the approach in the form of a physical test rig. Several experiments were carried out to determine the DEM parameters of six material–boundary pairs. The resulting parameters were adjusted using a refinement experiment. The results confirmed the adequacy of the developed approach, as well as its applicability in various conditions. The limitations of both the approach itself and its specific implementation in the form of a test rig were identified.

Authors: Vivas-Cortez Miguel , Fleitas Alberto , Guzmán Paulo M. , Nápoles Juan E. , Rosales Juan J.
Published: June 2021

In this communication, using a generalized conformable differential operator, a simulation of the well-known Newton’s law of cooling is made. In particular, we use the conformable t1−α, e(1−α)t and non-conformable t−α kernels. The analytical solution for each kernel is given in terms of the conformable order derivative 0<α≤1. Then, the method for inverse problem solving, using Bayesian estimation with real temperature data to calculate the parameters of interest, is applied. It is shown that these conformable approaches have an advantage with respect to ordinary derivatives.
A Novel Analog Circuit Soft Fault Diagnosis Method Based on Convolutional Neural Network and Backward Difference
Authors: Zhang Chenggong , Zha Daren , Wang Lei , Mu Nan
Published: June 2021

This paper develops a novel soft fault diagnosis approach for analog circuits. The proposed method employs the backward difference strategy to process the data, and a novel variant of convolutional neural network, i.e., convolutional neural network with global average pooling (CNN-GAP) is taken for feature extraction and fault classification. Specifically, the measured raw domain response signals are firstly processed by the backward difference strategy and the first-order and the second-order backward difference sequences are generated, which contain the signal variation and the rate of variation characteristics. Then, based on the one-dimensional convolutional neural network, the CNN-GAP is developed by introducing the global average pooling technical. Since global average pooling calculates each input vector’s mean value, the designed CNN-GAP could deal with different lengths of input signals and be applied to diagnose different circuits. Additionally, the first-order and the second-order backward difference sequences along with the raw domain response signals are directly fed into the CNN-GAP, in which the convolutional layers automatically extract and fuse multi-scale features. Finally, fault classification is performed by the fully connected layer of the CNN-GAP. The effectiveness of our proposal is verified by two benchmark circuits under symmetric and asymmetric fault conditions. Experimental results prove that the proposed method outperforms the existing methods in terms of diagnosis accuracy and reliability.
Integrated Inference of Asymmetric Protein Interaction Networks Using Dynamic Model and Individual Patient Proteomics Data
Authors: Yan Yan , Jiang Feng , Zhang Xinan , Tian Tianhai
Published: June 2021

Recent advances in experimental biology studies have produced large amount of molecular activity data. In particular, individual patient data provide non-time series information for the molecular activities in disease conditions. The challenge is how to design effective algorithms to infer regulatory networks using the individual patient datasets and consequently address the issue of network symmetry. This work is aimed at developing an efficient pipeline to reverse-engineer regulatory networks based on the individual patient proteomic data. The first step uses the SCOUT algorithm to infer the pseudo-time trajectory of individual patients. Then the path-consistent method with part mutual information is used to construct a static network that contains the potential protein interactions. To address the issue of network symmetry in terms of undirected symmetric network, a dynamic model of ordinary differential equations is used to further remove false interactions to derive asymmetric networks. In this work a dataset from triple-negative breast cancer patients is used to develop a protein-protein interaction network with 15 proteins.
Multi-Walled Carbon Nanotubes (MWCNTs) Cause Cellular Senescence in TGF-β Stimulated Lung Epithelial Cells
Authors: Lucas Joseph H. , Wang Qixin , Muthumalage Thivanka , Rahman Irfan
Published: June 2021

Multi-walled carbon nanotubes are engineered nanomaterials (ENMs) that have a fiber-like structure which may be a concern for the development of cellular senescence. Premature senescence, a state of irreversible cell cycle arrest, is implicated in the pathogenesis of chronic lung diseases such as pulmonary fibrosis (PF). However, the crosstalk between downstream pathways mediating fibrotic and senescent responses of MWCNTs is not well-defined. Here, we exposed human bronchial epithelial cells (BEAS-2B) to MWCNTs for up to 72 h and demonstrate that MWCNTs increase reactive oxygen species (ROS) production accompanied by inhibition of cell proliferation. In addition, MWCNT exposure resulted in the increase of p21 protein abundance and senescence associated β-galactosidase (SA β-gal) activity. We also determined that co-exposure with the cytokine, transforming growth factor-β (TGF-β) exacerbated cellular senescence indicated by increased protein levels of p21, p16, and γH2A.X. Furthermore, the production of fibronectin and plasminogen activator inhibitor (PAI-1) was significantly elevated with the co-exposure compared to MWCNT or TGF-β alone. Together, our study suggests that the cellular senescence potential of MWCNTs may be enhanced by pro-fibrotic mediators, such as TGF-β in the surrounding microenvironment.
Viral Bad News Sent by EVAIL

Published: June 2021

This article reviews the current knowledge on how viruses may utilize Extracellular Vesicle Assisted Inflammatory Load (EVAIL) to exert pathologic activities. Viruses are classically considered to exert their pathologic actions through acute or chronic infection followed by the host response. This host response causes the release of cytokines leading to vascular endothelial cell dysfunction and cardiovascular complications. However, viruses may employ an alternative pathway to soluble cytokine-induced pathologies—by initiating the release of extracellular vesicles (EVs), including exosomes. The best-understood example of this alternative pathway is human immunodeficiency virus (HIV)-elicited EVs and their propensity to harm vascular endothelial cells. Specifically, an HIV-encoded accessory protein called the “negative factor” (Nef) was demonstrated in EVs from the body fluids of HIV patients on successful combined antiretroviral therapy (ART); it was also demonstrated to be sufficient in inducing endothelial and cardiovascular dysfunction. This review will highlight HIV-Nef as an example of how HIV can produce EVs loaded with proinflammatory cargo to disseminate cardiovascular pathologies. It will further discuss whether EV production can explain SARS-CoV-2-mediated pulmonary and cardiovascular pathologies.
Relevance of Human Papillomaviruses in Head and Neck Cancer—What Remains in 2021 from a Clinician’s Point of View?
Authors: Hoffmann Markus , Quabius Elgar Susanne
Published: June 2021

Human papillomaviruses (HPV) cause a subset of head and neck cancers (HNSCC). HPV16 predominantly signs responsible for approximately 10% of all HNSCC and over 50% of tonsillar (T)SCCs. Prevalence rates depend on several factors, such as the geographical region where patients live, possibly due to different social and sexual habits. Smoking plays an important role, with non-smoking patients being mostly HPV-positive and smokers being mostly HPV-negative. This is of unparalleled clinical relevance, as the outcome of (non-smoking) HPV-positive patients is significantly better, albeit with standard and not with de-escalated therapies. The results of the first prospective de-escalation studies have dampened hopes that similar superior survival can be achieved with de-escalated therapy. In this context, it is important to note that the inclusion of p16INK4A (a surrogate marker for HPV-positivity) in the 8th TMN-classification has only prognostic, not therapeutic, intent. To avoid misclassification, highest precision in determining HPV-status is of utmost importance. Whenever possible, PCR-based methods, still referred to as the "gold standard”, should be used. New diagnostic antibodies represent some hope, e.g., to detect primaries and recurrences early. Prophylactic HPV vaccination should lead to a decline in HPV-driven HNSCC as well. This review discusses the above aspects in detail.
Copula-Based Infilling Methods for Daily Suspended Sediment Loads
Authors: Shiau Jenq-Tzong , Lien Yu-Cheng
Published: June 2021

Less-frequent and inadequate sampling of sediment data has negatively impacted the long and continuous records required for the design and operation of hydraulic facilities. This data-scarcity problem is often found in most river basins of Taiwan. This study aims to propose a parsimonious probabilistic model based on copulas to infill daily suspended sediment loads using streamflow discharge. A copula-based bivariate distribution model of sediment and discharge of the paired recorded data is constructed first. The conditional distribution of sediment load given observed discharge is used to provide probabilistic estimation of sediment loads. In addition, four different methods based on the derived conditional distribution of sediment load are used to give single-value estimations. The obtained outcomes of these methods associated with the results of the traditional sediment rating curve are compared with recorded data and evaluated in terms of root mean square error (RMSE), mean absolute percentage error (MAPE), Nash-Sutcliffe efficiency (NSE), and modified Nash-Sutcliffe efficiency (MNSE). The proposed approach is applied to the Janshou station located in eastern Taiwan with recorded daily data for the period of 1960–2019. The results indicate that the infilled sediments by the sediment rating curve exhibit better performance in RMSE and NSE, while the copula-based methods outperform in MAPE and MNSE. Additionally, the infilled sediments by the copula-based methods preserve scattered characteristics of observed sediment-discharge relationships and exhibit similar frequency distributions to that of recorded sediment data.
Physiological Responses of the Submerged Macrophyte Stuckenia pectinata to High Salinity and Irradiance Stress to Assess Eutrophication Management and Climatic Effects: An Integrative Approach

Published: June 2021

Stuckenia pectinata, a submerged macrophyte of eutrophic to hyper-eutrophic fresh to brackish waters, faces management and climatic-forced increment of salinity and irradiance in Vistonis Lake (Greece) that may endanger its existence and the ecosystem functioning. A pre-acclimated clone under low irradiance and salinity conditions was treated to understand the effects of high salinity and irradiance on a suite of subcellular (chlorophyll a fluorescence kinetics and JIP-test, and chlorophyll content) to organismal (relative growth rate—RGR) physiological parameters. The responses to high irradiance indicated the plant’s great photo-acclimation potential to regulate the number and size of the reaction centers and the photosynthetic electron transport chain by dissipation of the excess energy to heat. A statistically significant interaction (p < 0.01) of salinity and irradiance on Chl a, b content indicated acclimation potential through adjusting the Chl a, b contents. However, no significant (p > 0.05) difference was observed on Chl a/b ratio and the RGR, indicating the species’ potential to become acclimatized by reallocating resources to compensate for growth. Thus, the regulation of photosynthetic pigment content and photosystem II performance consisted of the primary growth strategy to present and future high salinity and irradiance stressful conditions due to eutrophication management and the ongoing climatic changes.
Bases para la construcción de un urbanismo prioritario para la reducción de la pobreza y la desigualdad social en Quibdó, Colombia. Propuesta de Plan de Indicadores y Líneas Estratégicas de Desarrollo Urbano
Authors: Borja Buitrago Diana
Published: June 2021

Quibdó es una ciudad Colombiana, capital del departamento del Chocó y una de las poblaciones más importantes en la región del Pacífico Colombiano. Pese a estar ubicada en una de las regiones más biodiversas del país, la ciudad presenta graves problemas de pobreza y desigualdad social. En el contexto nacional, esta ciudad no alcanza un nivel mínimo de desarrollo social en cuestiones de salud, vivienda, educación y servicios públicos. Debido a su retraso urbano y social, es necesario implementar medidas mediante las cuales la ciudad supere esta vulnerabilidad y alcance un grado de prosperidad urbana que mejore la calidad de vida para todos sus ciudadanos. Por tal razón, esta investigación propone un nuevo modelo de ciudad, denominado “urbanismo prioritario”. Se trata de un modelo adaptado para entornos con características de extrema pobreza. Asimismo, ofrece una forma de medición alternativa, basada en 15 dimensiones ligadas a los lineamientos del urbanismo prioritario. Estas dimensiones ofrecen 53 indicadores urbanos, cuya finalidad es medir de manera correcta la pobreza de la ciudad. El objetivo consiste en detectar sus problemas reales, y ofrecer un diagnóstico que posibilite un planteamiento adecuado de las líneas estratégicas para el futuro desarrollo urbano de Quibdó.
Tecnologias de Vigilância na Assistência Social

Published: June 2021

O artigo problematiza as novas tecnologias enquanto instrumentos gerenciais que adentram no âmbito da assistência social, demarcando traços sutis de controle sobre os mais pobres. Assim, o estudo objetiva adensar o debate sobre um possível chamado do serviço social à operacionalidade destes mecanismos que se avolumam num cenário de tendências regressivas em ações manipuladoras, fiscalizadoras que envolvem a profissão e que impactam escolhas e organizam a dominação por meio de estratégia passível de reproduzir uma conduta e um pensamento capazes de potencializar a vigia e a dominação. Recorremos à tradição marxista por meio de pesquisa bibliografia, bem como da análise documental, em que se percebe que, diante das evidências de uma clara ideologia conservadora, elementos nem sempre explícitos colocam requisições constrangedoras, acríticas, apoiadas em tecnologias cuja aderência a práticas retrógradas se afirmam como trato à questão social.

В данной статье раскрываются особенности формирования структуры цементных композиций с применением активной минеральной добавки вулканического происхождения. Полученные ре цептуры композиционных цементов позволят получать высококачественные бетоны с классом прочности от В60 до В100, снижать нормальную густоту бетонных смесей на 2530, при этом подвижность смеси остается постоянной. Кроме того, применение данной разработки позволит повышать темпы набора прочностных показателей бетона, что дает вероятность отказа от тепло вой обработки и способствует получению необходимой для распалубки прочности за промежуток времени 1824 часов. Работа выполнена в рамках исследований по реализации научного проекта 1848-200001 Высококачественные бетоны с повышенными эксплуатационными свойствами на основе местного природного и техногенного сырья , получившего поддержку Российского фонда фундаментальных исследований (РФФИ).

The article reveals the features of the formation of the structure of cement compositions using active mineral additives of volcanic origin. The resulting composition of composite cements will make it possible to obtain high-quality concrete with a strength class from B60 to B100, reduce the normal density of concrete mixtures by 2530, while the mobility of the mixture remains constant. In addition, the use of this development will allow increasing the pace of a set of strength indicators of concrete, which gives the probability of refusal from heat treatment and helps to obtain the strength necessary for stripping for a period of 1824 hours.

Titrimetric methods for determining the concentration of quaternary ammonium salts and polyhexame­thylenebiguanide hydrochloride in the presence of a disinfectant are described. In addition, as auxiliary components, the agent contains a nonionic surfactant and an alkyl polyglucoside and a disodium salt of ethylenediaminetetraacetic acid as a complexing agent. The main differences between the methods proposed by us for the determination of quaternary ammonium salts and polyhexamethylenebiguanide hydrochloride is the use of not sodium dodecyl sulfate as a titrant, but a solution of the disinfectant itself, which greatly facilitated the visual fixation of the equivalence point. In addition, the volume of the indicator (methylene blue and bromophenol blue) was selected in such a way that the exposure between the portions of the added titrant was not prolonged, because this would increase the overall duration of the analysis. When titrating with polyhexamethylenebiguanide hydrochloride, the vo­lume of the indicator is selected in such a way as to minimize the interfering effect of HR, which are also part of disinfectants. The reproducibility of the developed methods has been confirmed in accredited laboratories of the relevant state institutions of the Republic of Belarus. Metrological characteristics of the developed methods: accuracy index±3.7 %, reproducibility index 4.0 %, n = 17, P = 0.95 – to determine the QAS; accuracy index±4.2 %, reproducibility index 5.5 %, n = 17, P = 0.95 – for the determination of PHMBG.

Published: June 2021

Este vídeo sintetiza El papel de las Administraciones Públicas en las Políticas de Desarrollo Local: las Acciones de Facto con objeto de facilitar su comprensión al alumnado de cuarto curso del Grado en Relaciones Laborales y Recursos Humanos de la Universidad de Sevilla. La información mostrada se basa en Pérez & Carrillo (2000) *. Se parte de una incógnita, ¿Qué pueden hacer las Administraciones Públicas
para competir en Desarrollo Local?, pues ellas deben instaurar varios
desempeños desde ofertar el suelo industrial a fomentar la cultura
emprendedora. Se identifica al gobierno local como un agente de progreso y,
por lo tanto, como centro en el proceso de participación social atendiendo a las
características de la comunidad. El gobierno local debe crear un sistema de
gestión capaz de conciliar el crecimiento económico, la equidad (social,
económica y ambiental) y la sostenibilidad del desarrollo.
Terminamos referenciando este recurso didáctico al alumnado con inquietudes
en la política territorial. Se trata de un vídeo editado durante el curso 2020-2021
con el patrocinio del III Plan Propio de Docencia de la Universidad de Sevilla,
un documento que compendia unas nociones claves del Desarrollo Local.
