Personalidade, resiliência e bem-estar subjetivo de alunos do ensino superior

Este estudo tem como objetivo investigar as relações entre a personalidade, a resiliência e o bem-estar subjetivo de alunos do ensino superior, testando o valor preditivo que a resiliência possa acrescentar às dimensões da personalidade. A amostra é constituída por 197 participantes, com idades compreendidas entre os 18 e os 29 anos, de ambos os sexos. Para avaliar as variáveis em estudo foram aplicados o Big Five Inventory (BFI), a Escala de Satisfação com a Vida (SWLS), a Escala de Afetividade Positiva e Afetividade Negativa (PANAS) – versão reduzida, e a Escala Abreviada de Resiliência (BRS). Os resultados foram comparados em função do sexo e saída de casa dos pais, não se verificando, no entanto, diferenças estatisticamente significativas em nenhum dos dois. Foram encontradas correlações estatisticamente significativas entre afetividade negativa e neuroticismo. A resiliência correlacionou-se com a extroversão. Satisfação com a vida apresentou correlações significativas com amabilidade, conscienciosidade e resiliência. E ainda, a afetividade positiva apresentou correlação significativa com a resiliência, com a satisfação com a vida e com todas as dimensões da personalidade, menos com o neuroticismo. Os resultados indicam que, efetivamente, a personalidade é um forte preditor de bem-estar, e que a capacidade de resiliência apresenta relações positivas significativas com a satisfação com a vida e afetividade positiva e relação negativa com a afetividade negativa. ção negativa com a afetividade negativa.
Design of a Wideband RF Front End Based on Multilayer Technology

A wideband switched beam beamforming network based on an 8£8 Butler matrix is designed. This structure is implemented in a multilayer microstrip slot technology that employs two dielectric layers with common ground plane and coupling slots. Elliptically shaped microstrip hybrids and phase shifters are adopted to realize the required wide bandwidth. The flnal design of the Butler matrix provides a compact and without any crossovers beamforming network. The Butler matrix outputs feed a tapered slot Vivaldi antenna array that provides operating bandwidth covering the whole desired frequency range of 3.1 to 10.6GHz.
CROWDSOURCING INNOVATIONS AS A SEARCH PROCESS

ABSTRACT Crowdsourcing is increasingly used to create innovations. Despite the popularity of the approach, it is not known what its implications for the innovation processes are. This paper presents the results from a pilot study on crowdsourced, participatory innovation processes. Creation of innovations is framed as a search problem and a single case is analysed by comparing the crowdsourced innovation process to heuristics that individual inventors are known to use. INTRODUCTION Crowdsourcing, the act of outsourcing a task traditionally performed by an organization to an undefined crowd, has gained popularity as an approach to include more diverse groups of participants to innovation and design processes. Despite the popularity of the approach, clear best practices have not yet emerged. The situation may partially result from not knowing how crowdsourcing changes the innovation process. This paper is built on the assumption that creation of innovations can be framed as recombinant search over the space of possible solutions (Fleming and Sorensen 2001). The space of possibilities is naturally enormous, and therefore it is not possible to try out every solution. Instead, some other approach SEARCH HEURISTICS OFmust be used. While search algorithms on computers often rely on approaches such as local hill-climbing (Russell and Norvig 1995), this is not how humans typically create inventions. Rather, the individual inventors rely on more flexible search heuristics. (Maggitti et al. 2013). Under the paradigm of innovation as search, it is assumed that searching for solutions locally (i.e. focusing on the neighbourhood of solutions already familiar to the searching agent) is easy compared to distant search (searching for solutions not related to the current knowledge of the searching agent). Afuah and Tucci (2012) propose that problem solving through crowdsourcing works because it transforms the distant search to a local one. Crowdsourcing could therefore be considered as some kind of search algorithm. But how does that algorithm work, and how does it compare to the heuristics used by an individual inventor? This paper presents the results from a pilot study on crowdsourced, participatory innovation processes, aiming to clarify these research questions by framing the creation of innovations as a search problem. The contributions of the paper are twofold: 1) development of an approach for data collection and analysis to be used in further cases, and 2) analysis of the pilot case, which reveals that the algorithm used by the analysed crowdsourcing site can be described as a search-within-search. The algorithm resembles the heuristics used by individual inventors, but during the process each participant must still act as an individual inventor.
Unsupervised Video Summarization Based on An Encoder-Decoder Architecture

The purpose of video summarization is to facilitate large-scale video browsing. Video summarization is a short and concise synopsis of original video. It usually composed of a set of representative video frames from the original video. This paper solves the problem of unsupervised video summarization by developing a Video Summarization Network (VSN) to summarize videos, which is formulated as selecting a sparse subset of video frames that best represents the input video. VSN predicts a probability for each video frame, which indicates the possibility of a frame being selected, and then takes actions to select frames according to the probability distribution to form a video summary. We designed a novel loss function which takes into account the diversity and representativeness of the generated summarization without labels or user interaction.
Advancing the standard: venetoclax combined with intensive induction and consolidation therapy for acute myeloid leukemia

The B-cell lymphoma 2 (BCL-2) inhibitor venetoclax (VEN) in combination with lower-intensity therapy is an efficacious treatment for acute myeloid leukemia (AML). VEN in combination with the hypomethylating agent azacitidine improved rates of response and measurable residual disease (MRD)-negative remissions in addition to overall survival in the pivotal phase 3 VIALE-A trial compared with azacitidine monotherapy and has since emerged as the current standard of care in older or unfit patients with AML. In younger, fit patients with AML, intensive induction and consolidation chemotherapy (IC) is commonly employed as frontline therapy; however, relapse remains the principal cause of treatment failure in approximately 30–40% of patients. Improved IC regimens that increase MRD-negative response rates, result in durable remissions, and enable transition to curative allogeneic hematopoietic stem cell transplantation in appropriate patients remain an area of active inquiry. Preliminary results from trials investigating the combination of VEN with IC have reported promising findings to date, with composite complete remission and MRD-negative remission rates of approximately 89–94% and 82–93%, respectively, correlating with improved 12-month event-free and overall survival compared to historical outcomes with IC. Herein, we discuss ongoing trials investigating VEN in combination with IC in addition to outcomes within specific molecularly defined subgroups; review the molecular mechanisms of sensitivity and resistance to VEN, and highlight future combinations of VEN with novel targeted therapies for the treatment of AML.
Antimicrobial Resistance Patterns and Clonal Distribution of E. coli, Enterobacter spp. and Acinetobacter spp. Strains Isolated from Two Hospital Wastewater Plants

The objective of this study was to determine the presence and persistence of antimicrobial-resistant enterobacteria and their clonal distribution in hospital wastewater. A descriptive cross-sectional study was carried out in wastewater from two Mexico City tertiary level hospitals. In February and March of 2020, eight wastewater samples were collected and 26 isolates of enterobacteria were recovered, 19 (73.1%) isolates were identified as E. coli, 5 (19.2%) as Acinetobacter spp. and 2 (7.7%) as Enterobacter spp. Antimicrobial susceptibility profiles were performed using the VITEK 2® automated system and bacterial identification was performed by the Matrix-Assisted Laser Desorption/Ionization-Time of Flight mass spectrometry (MALDI-TOF MS®). ESBL genes were detected by polymerase chain reaction (PCR) and clonal distributions of isolates were determined by pulsed-field gel electrophoresis (PFGE). E. coli susceptibility to different classes of antimicrobials was analyzed and resistance was mainly detected as ESBLs and fluoroquinolones. One E. coli strain was resistant to doripenem, ertapenem, imipenem and meropenem. The analysis by PCR showed the presence of specific β-lactamases resistance genes (blaKPC, blaCTX-M). The PFGE separated the E. coli isolates into 19 different patterns (A–R). PFGE results of Acinetobacter spp. showed the presence of a majority clone A. Surveillance of antimicrobial resistance through hospital wastewater is an important tool for early detection of clonal clusters of clinically important bacteria with potential for dissemination.
Dicamba, Chlorsulfuron, and Clopyralid as Sprayer Contaminants on Sunflower (Helianthus annuus), Mustard (Brassica juncea), and Lentil (Lens culinaris), Respectively

Simulated sprayer tank residues of the broadleaf weed herbicides dicamba, chlorsulfuron, and clopyralid applied alone and with the grass weed herbicides sethoxydim and diclofop on sunflower, tame mustard, and lentil, respectively, caused visible crop injury and reduced dry weight and yield. Dry weight production in the greenhouse and crop tolerance ratings in the field indicated that the grass weed herbicides enhanced crop injury from dicamba, chlorsulfuron, and clopyralid. Yield reductions in field experiments were also greater when dicamba and clopyralid were mixed with grass weed herbicides and applied on sunflower and lentil, respectively. This did not occur with chlorsulfuron applied to mustard. When mixed with simulated broadleaf weed herbicide residues, diclofop enhanced dry weight reductions and crop injury and reduced yield to a greater extent than sethoxydim. Crop tolerance ratings differentiated treatments and rates but were not a good estimate of the extent of yield loss. When broadleaf weed herbicides were applied at rates simulating sprayer tank residues alone or combined with grass weed herbicides, yield losses ranged up to 40% in sunflower, 70% in mustard, and 95% in lentil, compared to the untreated check.
Enacting Asset-Based Approaches for Critically Conscious Dual Language Teachers: The Administrator’s Role in a Professional Learning Community

Equity minded administrators must perceive professional learning not only to focus on using strategies that promote language and literacy development for students, but also to address teachers’ deficit discourses and assumptions about their students (Molle, 2013; Kolano et al., 2014). Dual Language (DL) teachers and administrators participated in a professional learning community (PLC) to improve the instruction of DL learners by engaging in a critical examination of equity across three districts. The research used a framework to understand the cultural and linguistic assets of students by using a “learning about my students” approach with a focus on the strengths and abilities of their students––rather than deficits. Concurrently, the study examined the leadership role and collaboration of administrators in planning and implementing professional learning with their DL teachers. Results concluded key roles and supports of administrators to participants in the PLC as: 1) examining teacher’s critical consciousness, 2) leading with a cultural growth mindset, and 3) commitment to equity in capacity building.
Improving the Behavior of Steel Plate Shear Wall Using Double Infill Plates

Steel Plate Shear Wall (SPSW) has indicated suitable performance in numerical studies by researchers as well as in past earthquakes. Although this system has a considerable advantage, it requires huge columns to resist stress due to the infill plate, and this is one of the main dilemmas relating to this system. Also, increasing the infill plate made the system form plastic hinges in the columns instead of the infill plate and beam. To solve this problem, herein, an innovative model of SPSW is proposed as an alternative to the traditional type of steel shear wall, namely the use of Double Infill Plates for SPSW (DIP-SSW). The use of DIP-SSW as a resistance system against lateral loads, also results in space savings. The present numerical finite element investigation was performed by parametric study and consideration of the nonlinear behavior of this system. The results of the parametric study have been addressed. Also, the results showed that the DIP-SSW has an excellent ductility factor and capability of energy absorption under lateral loads.
Digital Twin: A Comprehensive Survey of Security Threats

Industry 4.0 is having an increasingly positive impact on the value chain by modernizing and optimizing the production and distribution processes. In this streamline, the digital twin (DT) is one of the most cutting-edge technologies of Industry 4.0, providing simulation capabilities to forecast, optimize and estimate states and configurations. In turn, these technological capabilities are encouraging industrial stakeholders to invest in the new paradigm, though an increased focus on the risks involved is really needed. More precisely, the deployment of a DT is based on the composition of technologies such as cyber-physical systems, the Industrial Internet of Things, edge computing, virtualization infrastructures, artificial intelligence and big data. However, the confluence of all these technologies and the implicit interaction with the physical counterpart of the DT in the real world generate multiple security threats that have not yet been sufficiently studied. In that context, this paper analyzes the current state of the DT paradigm and classifies the potential threats associated with it, taking into consideration its functionality layers and the operational requirements in order to achieve a more complete and useful classification. We also provide a preliminary set of security recommendations and approaches that can help to ensure the appropriate and trustworthy use of a DT.
Organisational BIM maturity models and their applications: a systematic literature review

ABSTRACT In the recent decade, there has been a significant increase in the number of maturity models offered in Building Information Modelling (BIM). However, several problems exist, such as no proper criteria for model choice for organisations and no adequate understanding of BIM maturity model (BIMMM) application areas. Thus, a systematic literature review (SLR) was undertaken using 32 papers published between 2010 and 2021, directed with a descriptive and content analysis, following the PRISMA standards. The results of this paper extend the knowledge on BIMMM development, application and validation. BIMMM development has always been initiated with a literature review on existing maturity models. National BIM Standard’s Interactive Capability Maturity Model is the most dominant base for developing and applying BIMMMs. However, the literature lacks applications and validation of mainstream models. The application of BIMMMs is mainly focused on assessing BIM performance, while a few studies tried to explore new avenues such as applying BIMMMs to other contexts, finding the relationship between maturity level and other factors, and understanding the impact of BIM maturity level on factors like project performance. Despite interviews and case studies being popular methods of model validation, doubts on the validity of the models have been raised due to the dearth of information on how most of the models were validated. The results of the study lead future research in the BIMMMs and inform the development and application of valid BIMMMs in practice.
Kinetic Analysis and CFD Modelling of Hydrogen-Air Combustion Applied to Scramjet Vehicles

- In the field of air-breathing hypersonic scramjet vehicles design and development, the Italian Aerospace Research Centre – CIRA has contributed to an international project, called Stratospheric Flying Opportunities for High-Speed Propulsion Concepts – STRATOFLY, in collaboration with several European organizations, coordinated by Politecnico di Torino under the EC Horizon 2020 programme financial support. Aim of this project was the improvement of enabling technologies for realization of a commercial hypersonic aircraft, able to flight at Mach 8, at 30÷35 km of altitude, for at least 4 hours with a minimum environmental impact and especially low NO x emissions. Understanding the complex, supersonic, turbulent, combustion processes occurring during scramjet operations is of fundamental importance. For this purpose, a thorough 0D kinetic assessment was carried out by means of the open-source Cantera software for identification of the most suitable kinetic mechanisms, able to predict with a satisfactory accuracy both the ignition delay times and the NO x emissions at the relevant scramjet operating conditions. Several kinetic schemes were investigated and the computed results were compared with the literature available shock tubes and rapid compression machines experimental data. In the entire investigated operative box, the best agreement, in terms of induction times, was achieved using the kinetic mechanism developed by Zettervall and Fureby. Moreover, for considering the generation of NO x, the three fundamental thermal route reactions by Zel’dovič, was added. Furthermore, full 3D CFD simulations were carried out in Ansys ® Fluent in order to compare experimental data and evaluate predictivity of such kinetic mechanisms. For the sake of comparison, the experiments carried out on the small-scale scramjet vehicle of LAPCAT-II by the HEG (DLR) were rebuilt.
Feature-based phishing detection technique

Phishing is an Internet fraud to entice unsuspecting victims. The tactic of phishing is to impersonate the trusted entities by employing both social engineering and technical subterfuge. Moreover, phishing is a form of online identity theft that creates a fake copy of popular site. There are many types of anti-phishing techniques available. However, they are mostly still in the infancy stage which may give false alarm to the user. Therefore, this research aims to develop a feature-based phishing detection technique to overcome the limitation. The proposed method involves aggregating new features with several existing features to form a sensitive features set. Based on the features set, the proposed method will utilise support vector machine to perform the classification. The experimental results show convincing performance with 95.33 percent of accuracy.
South Korea’s legacy of orphan adoption and the violation of adoptees’ rights to know their origins

South Korea experienced international scrutiny over its irregular intercountry adoption practices in the 1980s. However, it eventually came to be viewed as a model of transparent and efficient adoptions. This façade disguises an orphan adoption system that has become entrenched over the decades. Today, adoptees continue to lobby for their right to origins. This paper explores South Korea’s laws and policies, which nullified the rights of adoptees, and it calls for receiving countries to assume co-responsibility to restore these rights.
Reframing purpose and conceptions of success for a post-Covid-19 South African higher education

The Covid-19 pandemic raised immense challenges for universities. Staff and students had to quickly transition to an unfamiliar mode of emergency remote teaching and learning (ERTL) with its associated affordances and losses. The experiences of students and staff and the lessons learned during this time will affect the provision of teaching and learning in the future. During ERTL, a group of academics and teaching and learning support staff from different faculties at a large research-intensive public university in South Africa came together to support each other and share experiences of enhancing teaching and learning in higher education. This led to reflection on the impact of Covid-19 on the higher education landscape through community of practice. The aim of this conceptual paper is to discuss alternative notions of institutional purpose and lecturers’ conception of success that might influence the emerging post-Covid-19 higher education landscape in the global south. We claim that a more nuanced and critical understanding of these concepts is essential to evaluate the gains and losses experienced during Covid-19. Our argument hinges on our reflections of supporting teaching and learning during 2020 and 2021, and our observations of the challenges experienced by lecturers as they transitioned to ERTL. We suggest that it was in the moments of disruption and disequilibrium that lecturers were required to re-think the purpose of their courses and of higher education more broadly. Furthermore, it challenged us as a collective and individually to reflect critically on the measures of success within courses that changed dramatically in response to the prevailing circumstances, as well as more broadly within the sector.
The Shifting Morals of Moral Entrepreneurs

By utilizing manipulative tactics, such as persuasion techniques and strategies through social media sites, moral entrepreneurs can maintain and/or increase their scope of influence. In this article, we propose another tactic utilized by moral entrepreneurs, a concept we refer to as shifting morals. The complexity of moral entrepreneurs’ life experiences provides them with an endless set of social and moral norms that they can use to tweak their own ideals to encompass other moral framing networks to gain more followers and thus increase their influence. We examine theoretical literature, while also providing examples that resulted from content analysis from media websites to illustrate our proposed concept of shifting morals. We conclude that the shifting morals tactic is another tool moral entrepreneurs use to increase their influence in society to enact social change.
