How to manage generations? An Approach based on the Quality of Work Life

The objectives of this research are to examine whether there are significant differences in the perception of quality of work life among employees of three generational cohorts (i.e., Baby Boomers, Generation Xers and Millennials) and to propose some strategies from HRM in order to manage these differences. We used survey data collected from 522 employees of the logistic sector in Colombia and conducted internal consistency analysis, correlation analyses and one-way ANOVA. Results of ANOVA indicate that variables of quality of work life significantly differ depending on the generational membership of the employees. For example, Millennials were found to be a more distinct cohort from Gen Xers and Baby Boomers in terms of their relationship between promotion and career. However, the results suggest that employees in the older generations are likely to be more dedicated to, engrossed in, and even vigorous at work. For future studies, we recommend discussing how the knowledge on each generation in the workplace can inform specific HRM practices, such as how to train each generation effectively or to encourage each generation to improve work performance.

Dimension Analysis and Architectural Model of BAPNE Classroom for Pre-school and Primary Education

The aim of this article is to determine the relationship between architecture and teaching, providing functional architecture models that are capable of absorbing the teaching load for movement and, fundamentally, for the development of kinesthetic intelligence (Howard Gardner). For this, we will establish a metric range of spatial proportions, m2/student ratio, in accordance with the activities performed on the BAPNE method. This study will focus on students of Pre-school and Primary Education, providing specific standing architectural models and the minimum requirements for a classroom, as well as determining whether a space is suitable or not for the proposed activities. The method includes analyzing architecture of the basic teaching room, approaching other education systems (Dalcroze, Montessori) and determining the differences between those systems and BAPNE. This study is carried out by architects and engineers, directly noting the architectural needs that current teaching requires for user stimulation

Netflix in Web of Science: a bibliometric approach

Netflix has shaken up audiovisual industry, but what about academic research? This bibliometric analysis focuses on 210 papers indexed in Web of Science that address this issue. We examine the author, university of affiliation, language, journal, keywords, year of publication, citations received, and categories covered in WoS. We also conducted a quantitative analysis of abstracts and papers to identify the most recurrent methodologies, themes, and samples. Our results highlight a rise in Netflix studies in recent years and their tendency to analyse specific audiovisual works. There are many qualitative analysis of specific Netflix hits, but none of the shows particularly stands out. It also shows a rise in “Communication” and “Film, Radio & Television” papers (40% of them), although academic interest relies on Netflix corporate culture, business, and algorithm. These studies are mainly carried out using a qualitative methodology (83%). More than half of the articles focus on one of the Netflix series and, among them, the greatest interest lies in the representation of specific issues; gender, race and sexuality are present in 25% of the works in the sample (n=210). At the same time, among the 367 authors signing these research papers, the parity between men (51%) and women (49%) is almost absolute. It appears that the geographical and linguistic variety of papers is related to Netflix’s global expansion and that the sheer number of titles covered reveals a fleeting attention due to Netflix’s trademark: swift and concentrated consumption.Netflix ha revolucionado la industria audiovisual, pero ¿y la investigación académica? Este análisis bibliométrico se centra en 210 artículos indexados en Web of Science que abordan esta cuestión. Examinamos el autor, la universidad de afiliación, el idioma, la revista, las palabras clave, el año de publicación, las citas recibidas y las categorías cubiertas en WoS. También realizamos un análisis cuantitativo de los resúmenes y los artículos para identificar las metodologías, los temas y las muestras más recurrentes. Se evidencia un aumento de los estudios sobre Netflix en los últimos años y una tendencia a analizar obras específicas (aunque ninguna destaca especialmente). También aumentan los trabajos sobre “Comunicación” y “Cine, Radio y Televisión” (40 %), aunque el interés académico se centra en la cultura corporativa, el negocio y el algoritmo de Netflix. Estos estudios se realizan principalmente con una metodología cualitativa (83 %). Más de la mitad de los artículos se centran en una de las series de Netflix y, entre ellos, el mayor interés radica en la representación de temas específicos; el género, la raza y la sexualidad están presentes en el 25 % de la muestra (n=210). Al mismo tiempo, entre los 367 autores, la paridad entre hombres (51 %) y mujeres (49 %) es casi absoluta. La variedad geográfica y lingüística de los trabajos responde a la expansión mundial de Netflix y el gran número de títulos tratados revela una atención fugaz debida a la propia identidad de marca de Netflix: su consumo rápido y concentrado

Multiple hybridization events, polyploidy and low postmating isolation entangle the evolution of neotropical species of Epidendrum (Orchidaceae)

Background: Hybridization and polyploidy are central processes in evolution and speciation. These mechanisms often lead to complex patterns of genetic variation and the creation of novel genotypes, which may establish if they become isolated from gene flow. However, in the absence of reproductive isolation, species boundaries might easily be disrupted. Here, we used a combination of AFLPs, chloroplast DNA markers and flow cytometry to investigate the evolutionary outcomes of hybridization between two endemic Ecuadorian species of Epidendrum (E. madsenii and E. rhopalostele) in three hybrid zones. Postmating isolation was also quantified to determine the role of this barrier in restraining gene flow between hybrids and the parental species. In addition, future ecological niche models were constructed to predict the outcomes of hybridization between these species. Results: Our results confirmed the presence of hybrids in all hybrid zones, but revealed that a third parental species (E. falcisepalum) has contributed to one of the hybrid zones studied. Backcross genotypes were frequent in all hybrid zones, which was in accordance with the absence of strong reproductive barriers. The process of hybridization was highly asymmetric and followed in some cases by polyploidy. The projection of future niche models predicted a severe reduction in the area suitable for the occurrence of these species, although favorable conditions will still occur for the existence of the current hybrid zones. Conclusions: The recurrent process of hybridization has compromised the genetic integrity of the parental species. Most individuals of the parental species can no longer be considered as pure-bred individuals because most were classified as backcrossed hybrids. Novel genetic lineages occur in all hybrid zones implying that hybrids are fertile and can compete with the parental species. These results, together with the prediction of suitable conditions for the future occurrence of these hybrid zones, highlight the importance of conserving these geographic areas as sources of novel taxonomic entities

Late Quaternary monogenetic volcanoes along Río Salado, Sothwest Mendoza Province, Argentina

On the eastem flank of the Andes, to the north of Río Salado in southwest Mendoza Province (35º07'S-35º10'S), there are 4 monogenetic cones with blocky lava flows. A western group of small volcanoes, Hoyada, Lagunita and Loma Negra, with a total volume of -0.2 km3, are composed of amphibole-bearing basaltic andesite, and the eastem, more voluminous Hoyo Colorado volcano, with 0.44 km3 is composed of olivine (+ oxidised amphibole) basaltic andesite. Although data indicate they were emitted through successive, strombolian eruptions, they are overall coeval and the youngest Late Pleistocene volcanoes located in an "extra-Andean" setting, -70 km east of the main volcanic front. The magmas of the westem group of monogenetic cones show petrographic and geochemical characteristics that support processes of crustal interaction during ascent. In contrast, the magmas of the Hoyo Colorado volcano had a more direct ascent. Structural characteristics of the basement rocks to the volcanoes and the current seismotectonic activity of the Andes at this latitude indicate that the monogenetic cones of Río Salado were emplaced in a dominantly compressive tectonic regime

Localization of the genes controlling B chromosome transmission rate in maize (Zea mays ssp. mays, Poaceae)

In previous papers we found that the frequency of B chromosomes in native races of maize varies considerably in different populations. Moreover, we found genotypes that control high and low transmission rates (TR) of B chromosomes in the Pisingallo race. In the present work crosses were made to determine whether the genes controlling B-TR are located on the normal chromosome set (As) or on the B chromosomes (Bs). We made female f.0B x male m.2B crosses between and within high (H) and low (L) B-TR groups. The Bs were transmitted on the male side in all cases. The mean B-TR from the progeny of f.0B (H) x m.2B (H) and f.0B (H) x m.2B (L) crosses was significantly higher than that from f.0B (L) x m.2B (L) and f.0B (L) x m.2B (H) crosses. The results show that the B-TR of the crosses corresponds to the H or L B-TR of the 0B female parents irrespective of the Bs of the male parent. This indicates that B-TR is genetically controlled by the 0B female parent and that these genes are located on the A chromosomes.Fil:Chiavarino, A.M. Universidad de Buenos Aires.

Synergistic Antifungal Study of PEGylated Graphene Oxides and Copper Nanoparticles against Candida albicans

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/).The coupling reactions of polyethylene glycol (PEG) with two different nano-carbonaceous materials, graphene oxide (GO) and expanded graphene oxide (EGO), were achieved by amide bond formations. These reactions yielded PEGylated graphene oxides, GO-PEG and EGO-PEG. Whilst presence of the newly formed amide links (NH-CO) were confirmed by FTIR stretches observed at 1732 cm−1 and 1712 cm−1, the associated Raman D- and G-bands resonated at 1311/1318 cm−1 and 1584/1595 cm−1 had shown the carbonaceous structures in both PEGylated products remain unchanged. Whilst SEM images revealed the nano-sheet structures in all the GO derivatives (GO/EGO and GO-PEG/EGO-PEG), TEM images clearly showed the nano-structures of both GO-PEG and EGO-PEG had undergone significant morphological changes from their starting materials after the PEGylated processes. The successful PEGylations were also indicated by the change of pH values measured in the starting GO/EGO (pH 2.6–3.3) and the PEGylated GO-PEG/EGO-PEG (pH 6.6–6.9) products. Initial antifungal activities of selective metallic nanomaterials (ZnO and Cu) and the four GO derivatives were screened against Candida albicans using the in vitro cut-well method. Whilst the haemocytometer count indicated GO-PEG and copper nanoparticles (CuNPs) exhibited the best antifungal effects, the corresponding SEM images showed C. albicans had, respectively, undergone extensive shrinkage and porosity deformations. Synergistic antifungal effects all GO derivatives in various ratio of CuNPs combinations were determined by assessing C. albicans viabilities using broth dilution assays. The best synergistic effects were observed when a 30:70 ratio of GO/GO-PEG combined with CuNPs, where MIC50 185–225 μm/mL were recorded. Moreover, the decreased antifungal activities observed in EGO and EGO-PEG may be explained by their poor colloidal stability with increasing nanoparticle concentrations.Peer reviewe
