This paper discusses the results of new research at the farm level regarding farmers’ responses to climate change. These results are placed in the context of existing literature. The topics include the benefits of adaptation, the forms of adaptation, and the drivers of adaptation such as land tenure, water allocation systems, the operation of labor markets, and the extent of social capital. Moreover, this paper examines farmers’ responses to market signals as they consider adaptation options and the connections of these options with infrastructure quality. It also reviews policy options that support adaptation.
Francis Bacon (1909-1992)
Authors: Jedlińska Eleonora
Published: December 2021

Francis Bacon painted pictures based mostly on photographs published in encyclopaedias, popular magazines, the tabloid press, posters and packaging. He was interested in reproductions of paintings by great masters. He used photographs by Muybridge. Photographs, treated by Bacon as tools, were later “worked on” by the artist, becoming the canvas for his paintings. The scenes he chose – often drastic, depicting rape and violence – were painted into his canvases, creating a deformed image of the world that “emerged” from the horrors of both world wars. He painted portraits based on his photographs of friends. These were usually people with whom the artist was emotionally connected. He painted self-portraits base on a series of photographs taken in automatic photography, from which he selected several to form the basis of his paintings. Real things and persons should exist in the fictional space assigned to them. By destroying literalism in painting, Bacon wanted to find the similarity desired in painting as its principal, so to rediscover realism. When painting a portrait, he tried to capture the appearance of the figure. After Francis Bacon’s death, his London studio (7, Reece Mews), restored by conservators, was “repeated” in the space of the Hugh Lane Gallery in Dublin. It contains about 7,500 objects, among them numerous photographs which had been torn up by the artist, photographs of his lovers and friends, black and white reproductions. The Bacon ‘archive’ collected in Dublin is now a silent hint of the creative process of the artist, who despite numerous studies devoted to him and recorded conversations, still remains one of the most inscrutable artists of the 20th century.
Students’ Perception of Secondary School Teachers’ Assessment with Specific Reference to the Subject of English
Authors: Blažević Tania , Blažević Mara Ruža
Published: December 2021

Using research investigating the effect of teacher assessment practices in secondary schooling in Croatia on student perceptions of fairness, this paper1 points out participating students’ perception of fairness of assessment, focusing on teacher assessment in three secondary school subjects, but particularly in the subject of English. The research overall included enquiry into the fairness of teacher assessment practices in three secondary school subjects. The implemented research was both of a quantitative and qualitative nature. The research design was intended to be both empirical, measuring students’ perception, and quasi-ethnographic, seeking to interpret these perceptions through understanding the context. Student questionnaires, involving a total of 330 students, teacher interviews, involving a total of 12 teachers, and analysis of teachers’ assessment documents were used to collect data that were then analysed within case studies. Each case study, totalling six in number, represented a teacher with two classes of students studying one of the chosen three subjects. Classes of secondary school students from two high schools studying the subjects of Biology, Croatian or English as a foreign language formed the sample groups. These students were asked to complete a questionnaire based on Likert response type items founded on the Student Perception of Assessment Questionnaire (SPAQ) and open-ended questions based on a questionnaire developed at the Centre for Schooling and Learning Technologies (CSaLT). The SPAQ items were measured by five scales. The teachers of these students were interviewed and also provided documents that illustrate how they assessed students in these three subjects. The investigation uncovered variations in responses to teachers and subjects and differences in student response between classes of the same teacher which are possibly indicative, among other elements, of the role of teacher personality factors. This investigation revealed that from the three secondary school subjects researched, students’ perception of the secondary school subject of English achieved the most positive rating among the sample of students involved in the research.
Rađanje i nestanak jedne konceptualne integracije ili uspon i pad Kukuriku-koalicije
Authors: Babić Snježana , Gradečak Tanja
Published: December 2021

U ovome radu istražit će se uvjeti nastajanja i rok trajanja, tj. opstojnost jedne konceptualne integracije koja se pojavljivala u hrvatskome političkom diskursu za vrijeme predizborne promidžbe za parlamentarne izbore 2011. godine. Riječ je o blendu Kukuriku-koalicija koji je svojevremeno bio općeprihvaćen među političarima, ali i građanima Republike Hrvatske. Pojavljivao se u svim medijima, upotrebljavali su ga svi političari, jednako oponenti spomenute koalicije i njezini pripadnici. Iako je istodobno bio omiljen i omražen, premda se upotrebljavao izuzetno često, nakon određenog vremena ipak postupno nestaje iz jezične upotrebe. Ilustrirat ćemo stoga u ovome radu rađanje ove konceptualne integracije. Prikazat ćemo kada se ova konceptualna integracija najviše upotrebljavala te ćemo analizom anketnih odgovora i primjera prikupljenih s mrežnih stranica u razdoblju zadnjih godinu dana pokušati objasniti razlog(e) njezina nestanka iz današnjega političkog diskursa.
ARE CORPORATE SOCIAL RESPONSIBILITY ACTIVE FIRMS LESS INVOLVED IN EARNINGS MANAGEMENT? EMPIRICAL EVIDENCE FROM CHINA
Authors: Pasko Oleh , Chen Fuli , Proskurina Nelia , Mao Rong , Gryn Viktoriia , Pushkar Iryna
Published: December 2021

This paper investigates whether corporate social responsibility active (CSR active) firms operate dissimilarly from other firms in their financial reporting. Specifically, we examine whether the corporate social responsibility (CSR) attitude of a firm sways its reporting incentives, in respect of the extent of earning management. To test our predictions, we use a sample of 25,861 year-company observations, corresponding to 3538 Chinese listed companies, for the period 2009–2019. We find a significant positive association between CSR activity and earning management assessed by the level of discretionary accruals in Chinese listed companies. Moreover, we document that Chinese CSR active firms engage more in earnings management through discretionary accruals than CSR inactive firms. These findings are consistent with the opportunistic financial reporting hypothesis: advances in CSR used by managers to safeguard their position by evading scrutiny from stakeholder activists. This study contributes to the growing awareness among investors, stakeholders and researchers that we should distinguish between CSR active firms and socially responsible firms and that being the latter entail something more than just mechanically produce CSR reports.

We present a population of 19 radio-luminous supernovae (SNe) with emission reaching L

ν
∼ 1026–1029 erg s−1 Hz−1 in the first epoch of the Very Large Array Sky Survey (VLASS) at 2–4 GHz. Our sample includes one long gamma-ray burst, SN 2017iuk/GRB 171205A, and 18 core-collapse SNe detected at ≈1–60 yr after explosion. No thermonuclear explosion shows evidence for bright radio emission, and hydrogen-poor progenitors dominate the subsample of core-collapse events with spectroscopic classification at the time of explosion (79%). We interpret these findings in the context of the expected radio emission from the forward shock interaction with the circumstellar medium (CSM). We conclude that these observations require a departure from the single wind–like density profile (i.e., ρ
CSM ∝ r
−2) that is expected around massive stars and/or from a spherical Newtonian shock. Viable alternatives include the shock interaction with a detached, dense shell of CSM formed by a large effective progenitor mass-loss rate,

However, none of the VLASS SNe with archival data points are consistent with our model off-axis jet light curves. Future multiwavelength observations will distinguish among these scenarios. Our VLASS source catalogs, which were used to perform the VLASS cross-matching, are publicly available at https://doi.org/10.5281/zenodo.4895112.
Symmetry Breaking in Dynamical Encounters in the Disks of Active Galactic Nuclei
Authors: Wang Yi-Han , McKernan Barry , Ford Saavik , Perna Rosalba , Leigh Nathan W. C. , Low Mordecai-Mark Mac
Published: December 2021

The disks of active galactic nuclei (AGNs) may be important sites of binary black hole (BBH) mergers. Here we show via numerical experiments with the high-accuracy, high-precision code SpaceHub that broken symmetry in dynamical encounters in AGN disks can lead to asymmetry between prograde and retrograde BBH mergers. The direction of the hardening asymmetry depends on the initial binary semimajor axis. Under the assumption that the spin of the BHs becomes aligned with the angular momentum of the disk on a short timescale compared with the encounter timescale, an asymmetric distribution of mass-weighted projected spin χ
eff is predicted in LIGO–Virgo detections of BBH mergers from AGN disks. In particular, this model predicts that positive χ
eff BBH mergers are most likely for encounters with massive tertiaries in migration traps at radial distances ≳500–600 gravitational radii.
Synanthropization and species diversityof floodplain ecosystems of the Ob-Irtysh basin, Russia
Authors: Popova Elena I.
Published: December 2021

Currently, the phytocenoses of the Irtysh floodplain are experiencing intense anthropogenic pressures due to the intensive development of the oil and gas industry, as well as the urbanization of the territory. This paper focuses on the structure and species composition of the 27 studied areas in the floodplain ecosystems of the Ob-Irtysh basin. As a result of the research, we found 111 species of vascular plants from 33 families in plant communities. The areas belong to meadows and forest vegetation are represented by (1) birch forests (33%), (2) pine forests (10%), (3) fir forests (8%), (4) aspen forests (4%) and (5) associations of meadows (45%). Furthermore, we conducted a comparative analysis of the studied phytocenoses according to the Drude scale. To determine the anthropogenic transformation of the flora and individual plant communities, we determined the synanthropization index (the ratio of synanthropic species to the total number of species). In the synanthropic flora fraction, we distinguished 45 species belonging to 12 families, with the most multispecies being Apiaceae, Scrophulariaceae, Compositeae, Ranunculaceae, Poaceae, Fabaceae, Plantaginaceae. The synanthropization index of the studied phytocenoses ranges from 6.6% to 81.2%. The largest number of synanthropic species occurs in meadow associations, the content of synanthropes is greater than 50%, the structure is becoming more superficial, and the productivity and stability of plant communities are changing. The study of the horizontal structure of grass stands of meadow phytocenoses makes it possible to find the variability of different years, the change of dominant species and the stability of the species composition. Currently, researchers are paying considerable attention to the analysis of the structure of the herbage, since its study is of great theoretical and practical importance in clarifying phytocenotic relations.
« Nous les femmes on est une sous-culture dans l’autisme ». Expériences et point de vue de femmes autistes sur le genre et l’accompagnement
Authors: Courcy Isabelle
Published: December 2021

L’expérience de vie telle que communiquée par les personnes autistes est peu documentée, et la situation est d’autant plus dramatique en ce qui a trait aux femmes. Face à ce constat, on peut craindre que les interventions et les accompagnements offerts ne répondent pas adéquatement aux besoins de ces femmes. Cet article présente les résultats d’une recherche menée auprès de 17 femmes autistes du Québec et propose une réflexion à partir de leurs expériences afin d’améliorer le travail d’accompagnement. Des entretiens compréhensifs enrichis par la photo-élicitation ont été réalisés. Les résultats mettent en exergue l’importance de l’analyse de genre et de la prise en compte des expériences des femmes autistes à partir de leurs propres schèmes d’interprétation afin d’améliorer avec elles le travail d’accompagnement et de proposer une posture privilégiée pour analyser les interactions sociales et le genre.
Asymptotic $ H^2$ regularity of a stochastic reaction-diffusion equation

Published: December 2021

In this paper we study the asymptotic dynamics for the weak solutions of the following stochastic reaction-diffusion equation defined on a bounded smooth domain \begin{document}$ {\mathcal{O}} \subset {\mathbb{R}}^N $\end{document}, \begin{document}$ N \leqslant 3 $\end{document}, with Dirichlet boundary condition:

   \begin{document}$ \begin{equation} \nonumber\begin{aligned} { {{\rm{d}}} u } +(-\Delta u + u ^3- \beta u ) {{\rm{d}}} t = g(x) {{\rm{d}}} t+h(x) {{\rm{d}}} W , \quad u|_{t = 0} = u_0\in H: = L^2( {\mathcal{O}}), \end{aligned} \end{equation} $\end{document}

where \begin{document}$ \beta>0 $\end{document}, \begin{document}$ g\in H $\end{document}, and \begin{document}$ W $\end{document} a scalar and two-sided Wiener process with a regular perturbation intensity \begin{document}$ h $\end{document}. We first construct an \begin{document}$ H^2 $\end{document} tempered random absorbing set of the system, and then prove an \begin{document}$ (H,H^2) $\end{document}-smoothing property and conclude that the random attractor of the system is in fact a finite-dimensional tempered random set in \begin{document}$ H^2 $\end{document} and pullback attracts tempered random sets in \begin{document}$ H $\end{document} under the topology of \begin{document}$ H^2 $\end{document}. The main technique we shall employ is comparing the regularity of the stochastic equation to that of the corresponding deterministic equation for which the asymptotic \begin{document}$ H^2 $\end{document} regularity is already known.

Published: December 2021

SARS-CoV-2 is the newly emerged infectious disease that started in Wuhan, China, in early December 2019 and has spread the world over very quickly, causing severe infections and death. Recently, vaccines have been used to curtail the severity of the disease without a permanent cure. The fractional-order models are beneficial for understanding disease epidemics as they tend to capture the memory and non-locality effects for mathematical models. In the present study, we analyze a deterministic and fractional epidemic model of COVID-19 for Indonesia, incorporating vaccination and environmental transmission of the pathogen. Further, the model is fitted to Indonesia's active cases data from 1 June 2021 to 20 July 2021, which helped determine the model parameters' value for our numerical simulation. Mathematical analyses such as boundedness, existence and uniqueness, reproduction number, and bifurcation were presented. Numerical simulations of the integer and fractional-order model were also carried out. The results obtained from the numerical simulations show that an increase in the contact rate of the virus transmission from the environment leads to an increase in the spread of SARS-CoV-2. In contrast, an increase in the vaccination rate negatively impacts on our model basic reproduction number. These results envisage here are essential for the control and possibly eradicate COVID-19 in Indonesia.
Claves de la composición cantollanista en la España de la Baja Edad Media: el oficio rimado de san Froilán, obispo de León
Authors: Ruiz Torres Santiago
Published: December 2021

La composición de oficios en verso representa una de las formas de expresión litúrgica más íntimamente ligadas a la Baja Edad Media. El conocimiento del género dista, sin embargo, de ser completo, en parte por la escasa atención que ha recibido el canto llano tardío hasta fecha reciente, pero también por su marcado localismo. Muchos de estos oficios se concibieron, de hecho, como vehículo con el que honrar al santo titular de una iglesia o monasterio determinados. Ello, a la postre, ha condicionado que sus fuentes sean limitadas amén de dispersas, a menudo carentes de notación musical. Estas páginas tienen por objeto el estudio del oficio rimado de san Froilán (832-905), quien fuera ermitaño y luego obispo de León. El interés del mismo reside fundamentalmente en su conservación en dos versiones musicales distintas: la primera y más importante, un breviario de Sanctis de los siglos XIII-XIV conservado en el Archivo de la Catedral de Lugo, que transmite el oficio completo; y por otro lado, el procesional ms. 9 del Archivo Catedralicio de León, de fines del siglo XIV, con cinco responsorios. Fuera de la edición de sus textos y algunas noticias dispersas, nada se sabe de este repertorio. A partir de su análisis pormenorizado pretendemos conocer cuáles fueron las directrices técnicas y estéticas que guiaron su composición, así como su adecuación con el corpus gregoriano más primitivo. Las evidencias recabadas posibilitarán, asimismo, aproximarnos a la datación cronológica del oficio y posible ubicación de sus artífices.
‘Den lugar a los negrillos’: villancicos y danzas ‘de negro’ en la España del siglo XVII
Authors: Pujol-Coll Josep
Published: December 2021

Este artículo analiza la aparición de los bailes en los villancicos “de negro” para indagar sobre la contribución de los iberoafricanos en la cultura musical y coreográfica de la España del siglo XVII. Concretamente, a partir de un corpus de cincuenta textos, se toman en cuenta los bailes y danzas que aparecen descritos en ellos, especialmente los guineos, los zarambeques y cumbés, aunque también otros no directamente relacionados con los bailes considerados “de negros”, como la chacona, la zarabanda o el canario, así como otros bailes citados. Después de enumerarlos, clasificarlos y contextualizarlos, se interrelacionan estos bailes con los que aparecen en las procesiones de Corpus, para finalmente ofrecer una mirada intertextual sobre los filtros que actuaban delante de la realidad esclava, para dilucidar la participación africana y distinguirla de los casos de blackface y otras hibridaciones culturales a lo largo del siglo.
La música de Carmen, la de Triana (1938): las fuentes y el proceso creativo
Authors: Fernández de Larrinoa Rafael
Published: December 2021

Considerada una pieza clave de la incipiente propaganda franquista, la coproducción cinematográfica hispano-alemana Carmen, la de Triana (Florián Rey, 1938), rodada en Berlín en plena guerra civil española, ha sido ampliamente escrutada desde distintos enfoques culturales y políticos. Enmarcado en el creciente interés hacia el cine por parte de la musicología española, este filme ha sido estudiado por Laura Miranda (2018 y 2021) desde una perspectiva principalmente cultural e identitaria. Nuestro estudio, en cambio, adopta un enfoque esencialmente filológico y se centra —principal, pero no exclusivamente— en la banda sonora del compositor linense José Muñoz Molleda (1905-1988) a partir del análisis de los materiales manuscritos de su fondo personal custodiados por el Centro de Documentación y Archivo (CEDOA) de la SGAE en Madrid, no estudiados hasta la fecha. El cotejo sistemático de las partituras de este fondo con la banda sonora del filme (y, en segundo plano, con su versión alemana) revela importantes cambios operados entre la fase de preproducción y su montaje final que permiten identificar importantes decisiones tomadas por el equipo artístico a lo largo de las fases intermedias. El análisis de las implicaciones de estas decisiones permitirá esclarecer y precisar algunos aspectos cruciales del proceso creativo cinematográfico de este filme, así como de su significado, tanto en el plano artístico como en el ideológico.
Promoting Students' Soft Skills in a Telecommunication Engineering Course with an Elevator Pitch Activity
Authors: Ferrando-Rocher Miguel , Marini Stephan
Published: December 2021

An elevator pitch is a short summary used to quickly and simply define a process, product, service, organization, or event and its value proposition. The name comes from the idea that it should be possible to deliver the sum-mary within the time span of an elevator ride, so anywhere between 30 sec-onds and 2 minutes, which means the key points need to get across quickly. In this particular educational context, technical students have been encour-aged to defend, under the typical rules of the elevator pitch, the knowledge acquired during the semester in a specific subject. This contribution focuses on the classroom experience and how the transversality of the activity can help students to strive and think in a different way than they are used to in the classroom of a technical career.
Teachers' Perspective on Personal Learning Environments via Learning Management Systems Platform
Authors: Alserhan Sarah , Yahaya Noraffandy
Published: December 2021

In recent years, the landscapes of teaching and learning has changed because of the utilization of information and communications technologies. In this context, the most illustrative innovations are Learning Management Systems (LMS) and Personal Learning Environments (PLEs). Despite of the LMS and PLEs popularity in ed-ucational contexts as well as the expand set of tools and services that they offer to learners and teachers; they are still in fancy stages. In order to present the challenges Personal Learning Environments were presented; however, it is obvious that PLEs will not replace LMS. Therefore, both types of environments should coexist and interact. In this manner, the current study took teachers’ perspective on integrating the third generation LMS into PLEs. In addition, this study conducted to find out the teachers’ perspective on how the LMS could enhance PLEs in terms of planning before applying the PLE's; designing a framework in the PLE’s; imple-menting the PLEs; interacting in PLEs; managing the learning process through the PLEs and utilizing technolo-gy in PLEs. The participants of the study were 575 teachers who were selected randomly from Saudi Arabia schools. The findings of this study found that teachers must apply a positive teaching approach, holding that knowledge is composed upon student-to-student interaction as well as student-to-teacher interaction. Further-more, this study revealed that teachers must enterprise, deliver, and support K-12 online learning.
Malware Detection Using Ensemble N-gram Opcode Sequences
Authors: Yeboah Paul Ntim , Amuquandoh Stephen Kweku , Musah Haruna Balle Baz
Published: December 2021

Conventional approaches to tackling malware attacks have proven to be futile at detecting never-before-seen (zero-day) malware. Research however has shown that zero-day malicious files are mostly semantic-preserving variants of already existing malware, which are generated via obfuscation methods. In this paper we propose and evaluate a machine learning based malware detection model using ensemble approach. We employ a strategy of ensemble where multiple feature sets generated from different n-gram sizes of opcode sequences are trained using a single classifier. Model predictions on the trained multi feature sets are weighted and combined on average to make a final verdict on whether a binary file is malicious or benign. To obtain optimal weight combination for the ensemble feature sets, we applied a grid search on a set of pre-defined weights in the range 0 to 1. With a balanced dataset of 2000 samples, an ensemble of n-gram opcode sequences of n sizes 1 and 2 with respective weight pair 0.3 and 0.7 yielded the best detection accuracy of 98.1% using random forest (RF) classifier. Ensemble n-gram sizes 2 and 3 obtained 99.7% as best precision using weight 0.5 for both models.

Effective mobile technology adoption also enhances knowledge management through mobile applications that allow information capture, storage, retrieval and sharing.  This study uses systematic literature review to collect information from post 2017 studies previous conducted by other researchers. Articles were searched through highly ranked databases from which 657 journals were identified. After the screening and eligibility assessment, 24 journals were retrieved. The back and forward search retrieved 4 more journals bringing the total to 28 journals that were included in the study. Based on this information, a conceptual model is developed to help assess the m-learning perceptions, adoption intentions and factors influencing its adoption among learning institutions in the gulf region. This model is built based on the Theory of Planned Behavior and Unified Theory of Acceptance and Use of Technology. Based on the developed model, main constructs such as performance expectancy, effort expectancy and social influence are greatly impacted by other factors like learner’s creativity and mobility.

The pandemic offers numerous applications of very basic microeconomics concepts and their extension to other aspects of economic life. It also creates an opportunity for better understanding of how the market works and its effects on the economy and society. Allocation of a scarce resource is the definition of economics. There have been countless examples of scarcity (toilet paper, vaccines). How do we decide how to allocate those goods, especially when the market fails? The pandemic is a classic illustration of tradeoffs. In particular, there are tradeoffs between shutting (or re-opening) the economy and loss of human life; a rational decision would compare the costs and the benefits. Lastly, there are countless examples of the unequal economic effects of the virus and their implications for public policy.
The Effect of the COVID-19 Pandemic on International Stock Exchanges

It is possible to define the concept of risk in various ways. Risk is the deviation possibility of the realized value from the expected value. It has two components, nonsystematic risk and systematic risk. Despite this, pandemics are risk factors that cannot be anticipated. They have deeply affected economies and financial markets under every condition. The importance of the detection of the COVID-19 pandemic comes from the selection of monetary and fiscal policies to be applied by governments during the rehabilitation process of economies. Equity share markets provide important information regarding the future of a company or economy. The reason for this is that the current value of an equity share is dependent on the deducted calculation of the cash flows of the equity share to be provided in the future. The actual price of the equity share is determined according to supply and demand under market conditions.

Authors: Shililu Henry Milimu
Published: December 2021

The purpose of this chapter is to report on the findings of a study that was conducted by the author to investigate the impact of job demands variables on emotional exhaustion and emotional ill-health. A sample of 173 drawn from employees who worked for different organizations in the Pacific, mainly Australia, the African region, the Indian subcontinent of India, Nepal, Pakistan, Bangladesh, and Sri Lanka, and employees who professed Christian and Hindu religions. A broad range of ages, occupations, ethnicities, religions, and cultures was represented in the sample, that is, the targeted population were employees whose different contexts and characteristics (e.g., attitudes, occupations, ages, marital status, religion, opinions, behaviors, and other defined variables) could be measured and allowed to generalize the results. The study used a quantitative research design. A diversity of findings were established with some findings being consistent with the JD-R theory and previous studies across the cultures while other findings were not consistent with previous studies and the JDR theory.

Workers are exposed to different factors that can be detrimental to their well-being, being the most known safety and hygiene factors. A few years ago, the concepts of harmful factors for workers were updated by adding the psychosocial factors. Although there is literature on psychosocial factors and their effect on health, this work focused specifically on seeking the relationship between productivity and psychosocial factors to know how it impacts the organization. The investigation was applied in a case study for a doorknob locks manufacturing company in its final assembly area. Data collection was done by applying the questionnaire provided by NOM-035-STPS-2018 and the company's productivity databases for the subsequent analysis using statistical tools. The results were that, for the violence factor, its correlation with productivity was R2 = 0.8886, indicating a strong correlation with which it is concluded that there is an influence on productivity.
Determinants of Employee Motivation

Published: December 2021

This chapter integrates collectivism with the dimensions of the Expectancy Theory to investigate the direct and indirect impact of horizontal and vertical collectivism on employee motivation of operational and non-operational staff. Data were collected from 205 employees using a cross-sectional survey. Hypotheses were tested with multiple regression analysis. Across both employee categories, horizontal collectivism improves motivation while vertical collectivism does not have a significant impact on motivation. Mediation effects were significant in the relationship between horizontal collectivism across both employee categories. However, there were some variations in the mediation effects on the relationship between vertical collaboration and motivation across the two categories. This chapter contributes to motivation literature by integrating the Expectancy Theory with two under-investigated dimensions of collectivism to compare motivation determinants among operational and non-operational staff. This chapter presents implications for managers and policy for improving employee motivation.

Published: December 2021

The use of exoskeletons in occupational tasks has increased significantly in the last five years. However, few comparative studies have been conducted to understand the advantages and disadvantages of existing exoskeletons. This chapter presents the comparison of six exoskeletons using the TOPSIS method. Using databases of patents and commercial products, a total of six that were chosen to be compared by experts in the design and/or use of exoskeletons. The criteria evaluated were exoskeleton weight, load capacity, anthropometric adjusts, maintenance, and installation on the user. The Shoulder-X exoskeleton was selected as the best, serving as a reference for the acquisition of characteristics for recommendations for the development of new models for use in occupational tasks.

Recently, the interest in being part of more competitive companies has increased. For this, organizations apply various strategies of continuous improvement that allow them to maintain high standards of competitiveness. In this sense, organizations make use of various techniques, tools, and methodologies that support the achievement of objectives. This research presents an approach towards the Six Sigma (SS) strategy, one of the main continuous improvement strategies used to achieve competitiveness. On the other hand, organizations currently seek that during manufacture of their products, caring for the environment is naturally part of their objectives, seeking to achieve benefits with a sustainable impact. Therefore, this research seeks to define the CSF for implementation of SS through a factor analysis that allows identifying the relationship between SS and obtaining sustainable benefits (SB) through its implementation.
HIV infection and increased risk of COVID-19 mortality: A Meta-Analysis
Authors: Kouhpayeh Hamidreza , Ansari Hossein
Published: December 2021

There are some concerns on the effect of infection with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) on the outcome and mortality of COVID-19. In this meta-analysis, we aimed to address this issue and assess the risk of mortality in COVID-19 patients who are co-infected with HIV. Two International electronic databases (PubMed, Scopus) were searched from the first time available to 12 August 2021. The targeted outcome was the pooled odds ratio to examine the effect of HIV infection on COVID-19 mortality. The crude odds ratio (OR) for all studies and the pooled OR were calculated with 95% confidence interval. The forest plot was used to graphically represent the result of conducted meta-analysis and calculated OR for individual studies. The I2 statistic was used to examine the Heterogeneity in the included studies. Eleven studies were included in our study consisting of 19,642,775 COVID-19 infected cases, 59,980 HIV-positive, and 4,373 deaths due to COVID-19 in HIV positive patients. The overall pooled odds ratio was 1.21 (CI: 1.02; 1.43) and P-value < 0.0277. The I^2 value was 89% (P-value < 0.0001), which shows that included studies are heterogeneous. In this study, the funnel plot analysis showed symmetry among the included studies. HIV-positive patients are 21% more likely to die because of COVID-19 infection than people without HIV. Special attention should be considered for the prevention and treatment of COVID-19 and consistent treatment for HIV infection, in HIV-positive patients.
Il paradigma dell’ecologia integrale e i fondamenti epistemologici della bioetica globale di Van Potter
Authors: Giacobello Maria Laura
Published: December 2021

L’ambiente è oggi gravemente ferito dalla crisi epocale in atto: tra le voci che si levano a tutela della Casa Comune emerge quella della Chiesa, attraverso lo sguardo di Papa Francesco che, con l’espressione ‘ecologia integrale’, fa esplicito riferimento alla consapevolezza che nella realtà tutto è connesso. A partire dall’urlo di ribellione della natura, l’ecologia integrale si assume, dunque, l’onere di promuovere un’istanza di rinnovamento radicale, che possa investire le categorie etiche ordinarie, fino a estendersi a quelle antropologiche e gnoseologiche poste alla base della prevalente cultura occidentale, fondata sul paradigma meccanicistico. Nell’ampia cornice di un ripensamento dei tradizionali confini dell’etica, l’ecologia integrale può rappresentare un paradigma culturale alternativo, reale espressione dello spirito del tempo. A tal proposito, si rivela particolarmente interessante e proficuo avviare una riflessione sulla straordinaria convergenza fra la prospettiva dell’ecologia integrale e quella della bioetica globale di Van Potter: già negli anni Settanta del Novecento, infatti, lo scienziato americano gettava i fondamenti epistemologici per una diversa visione etica. L’idea di un approccio sistemico volto a valorizzare la relazione delle singole parti tra di loro e col tutto, sia pure generata da presupposti evidentemente diversi, accomuna inequivocabilmente le due prospettive. E, in verità, la riflessione di Potter prende le mosse dalla stessa consapevolezza situata alla base dell’ecologia integrale, quella del profondo radicamento dell’uomo nell’ecosistema: mediante l’assunzione di una visione sistemica, che passa attraverso l’articolazione del concetto di biocibernetica, lo scienziato offre una valida rappresentazione del carattere interattivo dell’organizzazione strutturale che presiede al funzionamento dell’ambiente naturale.
The persuasion of vaccine allocation models during Covid-19. Rhetoric, ethics and science
Authors: Passaro Elvira , Picozzi Mario
Published: December 2021

The swift development of effective vaccines against the new coronavirus was an unprecedented scientific achievement. In this paper, we discuss what models have been proposed for distributing vaccines locally and globally through the application of Aristotelian rhetoric. This discussion, therefore, focuses on a specific question: how are the different models of vaccine administration and distribution justified on an ethical-argumentative level? This report also examines what has come to be known as “vaccine nationalism” through the lens of the early experience with the COVID- 19 vaccination process. To this end, this report proceeds as follows: Section I explains the rhetorical method applied to ethical principles, and Section II explains the chosen criteria for the analysis. Section III looks at the Fair Priority Model; Section IV examines the COVAX and GAVI model; Section V presents the weighted lottery model. Section VI proposes a summary table of the analysis of the proposed models and Section VII focuses on the ethical problem of vaccine nationalism and its implications in relation to the models, that were taken into consideration during the previous sections. Section VIII offers brief conclusions; solidarity conceived as an argument of reciprocity should be, according to this analysis, the guiding value to address ethical problems in the area of resource allocation.
