Transnational representation of a gendered recession in corporate dramas
The cinematic depiction of the financial crisis has centred on the explanation of the causes and consequences of the global recessionary scenario in which gender acquires special relevance. My aim in this article is to carry out a hitherto unaddressed transnational analysis of corporate dramas. More specifically, I elicit the commonalities as well as local specificities that different Western cinematographies show when tackling gendered recessionary discourses on ‘mancession’ and ‘austerity’. Films such as The Last Days of Lehman Brothers (Samuels, 2009, BBC), Money Never Sleeps (Stone, 2010), The Company Men (J. Wells, 2010) and The Big Short (McKay, 2015) have, on the one hand, aligned with nostalgic and retro-sexist discourses by focusing on male suffering to confront the recession while relegating female characters as emotional companions of the male hero. On the other hand, the representation of female characters in these films has also put to the test the inconsistencies of neoliberal discourses when analysed from the perspective of genre. To illustrate the transnational dimension of the ‘narrated’ impact of the ‘Global Financial Crisis’ in different scenarios, I compare a US Wall Street film and a Spanish corporate drama of the Great Recession: Margin Call (J Chandor, 2011, USA) and The Tip of the Iceberg (La punta del iceberg, D Cánovas, 2016, Spain)
Local Behavior of the First-Order Gradient Correction to the Thomas-Fermi Kinetic Energy Functional
The first order gradient correction to the Thomas-Fermi functional, proposed
by Haq, Chattaraj and Deb (Chem. Phys. Lett. vol. 81, 8031, 1984) has been
studied by evaluating both the total kinetic energy and the local kinetic
energy density. For testing the kinetic energy density we evaluate its
deviation from an exact result through a quality factor, a parameter that
reflects the quality of the functionals in a better way than their relative
errors. The study is performed on two different systems: light atoms (up to
Z=18) and a noninteracting model of fermions confined in a Coulombic-type
potential. It is found than this approximation gives very low relative errors
and a better local behavior than any of the usual generalized gradient
approximation semilocal kinetic density functionals.Comment: 7 pages, 2 tables, 4 figure
Kinetic Energy Density Study of Some Representative Semilocal Kinetic Energy Functionals
There is a number of explicit kinetic energy density functionals for
non-interacting electron systems that are obtained in terms of the electron
density and its derivatives. These semilocal functionals have been widely used
in the literature. In this work we present a comparative study of the kinetic
energy density of these semilocal functionals, stressing the importance of the
local behavior to assess the quality of the functionals. We propose a quality
factor that measures the local differences between the usual orbital-based
kinetic energy density distributions and the approximated ones, allowing to
ensure if the good results obtained for the total kinetic energies with these
semilocal functionals are due to their correct local performance or to error
cancellations. We have also included contributions coming from the laplacian of
the electron density to work with an infinite set of kinetic energy densities.
For all the functionals but one we have found that their success in the
evaluation of the total kinetic energy are due to global error cancellations,
whereas the local behavior of their kinetic energy density becomes worse than
that corresponding to the Thomas-Fermi functional.Comment: 12 pages, 3 figure
Coulomb effects on the transport properties of quantum dots in strong magnetic field
We investigate the transport properties of quantum dots placed in strong
magnetic field using a quantum-mechanical ' approach based on the 2D
tight-binding Hamiltonian with direct Coulomb interaction and the
Landauer-B\"{u}ttiker (LB) formalism. The electronic transmittance and the Hall
resistance show Coulomb oscillations and also prove multiple addition
processes. We identify this feature as the 'bunching' of electrons observed in
recent experiments and give an elementary explanation in terms of spectral
characteristics of the dot. The spatial distribution of the added electrons may
distinguish between edge and bulk states and it has specific features for
bunched electrons. The dependence of the charging energy on the number of
electrons is discussed for strong and vanishing magnetic field. The crossover
from the tunneling to quantum Hall regime is analyzed in terms of dot-lead
coupling.Comment: 17 pages,8 figures,Revtex,submitted to Physical Review
Professional Skills and Profiles in Journalism Demanded by Companies: Analysis of Offers at LinkedIn and Infojobs
The goal of this research is to analyze whether the profiles and professional skills in journalism demanded by companies in Spain correspond to those compiled in the Libro Blanco of the ANECA, or whether they have been modified over a decade later by the impact of the digital era and emergence of new employment needs. In the current setting of rapid and unpredictable changes, periodic analyses and research like this study are necessary. The methodology chosen was the analysis of the content of job offers directed to journalism graduates on the two most used job portals in Spain, Infojobs and LinkedIn, in September 2017. All the information in the offers was organized into two categories related to descriptive data about types of contracts and data over required skills. The results led to the conclusion that the professional skills currently demanded of journalism graduates differ qualitatively and quantitatively from the professional skills described by the ANECA in 2005. The skills most demanded by companies respond to the emergence of new professional profiles related to Web 2.0. However, it is also the case that companies do not seem to know precisely what skills a journalism graduate must have
Application of a flipped classroom for model-based learning in electronics
This paper investigates the effectiveness of the flipped classroom methodology to build conceptual knowledge mentalmodels. In particular, it examines the learning process and outcomes of 40 students of a course on Physical Electronics inthe last year of a bachelor’s degree program in Physics, for which specific educational resources have been developed toimplement the flipped classroom. Among them, non-interactive resources are better to present topics and ideas, whereasinteractive resources are more useful to establish links between them to build and check the models. The examined dataentail grades, laboratory reports and rubrics, outcomes of learning activities, and direct observation, showing that theflipped classroom improves the construction of mental models, providing teaching resources where the topics and mainideas are presented, developed and exercised, and allowing students to establish links to build and check the models.Furthermore, this strategy increases the personal commitment of the students, fostering autonomy and cooperation withpeers, all of which makes it an effective pedagogical tool to build knowledge mental models
ICT-based didactic strategies to build knowledge models in electronics in higher education
This paper presents a didactic strategy based on information and communication technologies (ICTs) to help students build knowledge mental models in the context of Higher Education. It presents a methodology that combines the flipped classroom with other active methodologies and traditional lessons to improve the teaching/learning process of Electronics in university studies in Physics. Using the flipped classroom as the main strategy, the proposed methodology allows devoting more classroom time to active learning so that the instructor can follow the student learning process and evaluate model construction, while at the same time it increases student implication and fosters autonomy and cooperation with peers, contributing to a better construction of knowledge mental models in Electronics
Rural smartness: Its determinants and impacts on rural economic welfare
Mukti, I. Y., Henseler, J., Aldea, A., Govindaraju, R., & Iacob, M. E. (2022). Rural smartness: Its determinants and impacts on rural economic welfare. Electronic Markets. [Advanced online article at 9 March 2022]. https://doi.org/10.1007/s12525-022-00526-2 ---------------------------- Funding Information: This research was carried out with the financial support of the Indonesia Endowment Fund for Education (LPDP) with grant number S-297/LPDP.3/2019, and supported by the Office of Communication and Information of West Java Province (Diskominfo Jabar) and Jabar Digital Service (JDS), Indonesia. In addition, we gratefully thanks to the anonymous reviewers for their helpful comments on the previous version of this manuscript.Solving urbanization problems, especially in developing countries, solely through the adoption of smartness in urban areas is insufficient as urbanization is mostly driven by the wide urban-rural economic gap. To narrow this gap, the adoption of smartness needs to be extended into rural areas. However, studies in that direction are still lacking. Therefore, we developed a theoretical model that explains the determinants of rural smartness and its subsequent consequences on rural economic welfare. We validated the model with survey data from 179 villages in West Java Province, Indonesia. The results suggest that rural smartness is determined by the interplay of organizational, environmental, and technological readiness, and has a strong positive impact on innovativeness which, in turn, improves the competitiveness of the rural business ecosystem. This model can serve as a reference for further studies of rural smartness and as the foundation for the design of information platforms supporting it.publishersversionepub_ahead_of_prin
Optical emission spectroscopy on Ar/N/sub 2/ and Ar/N/sub 2//C/sub 2/H/sub 2/ expanding thermal plasmas
This work has been carried out in connection with the possibilities to deposit carbon nitride materials by expansion thermal plasma assisted chemical vapour deposition (ETP-A-CVD). With the same technique high deposition rates and good quality a-Si:H and a-C:H materials have been obtained. A study of the intensity of atomic lines and molecular bands in a Ar/N/sub 2/ and Ar/N/sub 2//C/sub 2/H/sub 2/ expanding thermal plasma has been performed. In the case of the Ar/N/sub 2//C/sub 2/H/sub 2/ mixture rotational and vibrational temperatures were obtained by comparing computer simulated spectra of the CN(B/sup 2/ Sigma -X/sup 2/ Sigma , Delta v=0) spectral system bands with the experimental spectra. The CN ground state density is determined by taking into account the self-absorption of the CN band
Application of atmospheric pressure glow discharge (APGD) for deposition of thin silica like films on polymeric webs
Silica-like films were deposited on PEN and PET polymeric foils in atmospheric pressure glow discharge (APGD) in a roll-to-roll reactor open to ambient air. APGD was ignited in a mixture of inexpensive carrying gas argon and nitrogen with oxygen and hexamethyldisiloxane (HMDSO) precursor. The uniform diffuse glow in various gas mixtures was sustained by utilizing electronic stabilization network. APGD operation in air for a present setup was demonstrated. The contribution of different deposition mechanisms to the resulting silica-like film is discussed. The dependence of film structure and chemical composition on the conditions during deposition process was studied by means of SEM, ATR-FTIR and XPS analysis. The influence of oxidant concentration on the deposited film properties is analyzed and discussed
