Abstract
We present a photometric study of 17 SNe Ia based on multi-color (Johnson–Cousins–Bessell BVRI) data taken at Piszkéstető mountain station of Konkoly Observatory, Hungary between 2016 and 2018. We analyze the light curves (LCs) using the publicly available LC-fitter SNooPy2 to derive distance and reddening information. The bolometric LCs are fit with a radiation-diffusion Arnett model to get constraints on the physical parameters of the ejecta: the optical opacity, the ejected mass and the initial nickel mass in particular. We also study the pre-maximum, dereddened

color evolution by comparing our data with standard delayed detonation and pulsational delayed detonation models, and show that the 56Ni masses of the models that fit the

colors are consistent with those derived from the bolometric LC fitting. We find similar correlations between the ejecta parameters (e.g., ejecta mass, or 56Ni mass versus decline rate) as published recently by Scalzo et al. (2019).

Abstract
Star formation depends critically on cooling mechanisms in the interstellar medium (ISM); however, thermal properties of gas in galaxies at the peak epoch of star formation (z ∼ 2) remain poorly understood. A limiting factor in understanding the multiphase ISM is the lack of multiple tracers detected in the same galaxies, such as Polycyclic Aromatic Hydrocarbon (PAH) emission, a tracer of a critical photoelectric heating mechanism in interstellar gas, and [C ii] 158 μm fine-structure emission, a principal coolant. We present ALMA Band 9 observations targeting [C ii] in six z ∼ 2 star-forming galaxies with strong Spitzer IRS detections of PAH emission. All six galaxies are detected in dust continuum and marginally resolved. We compare the properties of PAH and [C ii] emission, and constrain their relationship as a function of total infrared luminosity (L
IR) and IR surface density. [C ii] emission is detected in one galaxy at high signal-to-noise (34σ), and we place a secure upper limit on a second source. The rest of our sample are not detected in [C ii] likely due to redshift uncertainties and narrow ALMA bandpass windows. Our results are consistent with the deficit in [C ii]/L
IR and PAH/L
IR observed in the literature. However, the ratio of [C ii] to PAH emission at z ∼ 2 is possibly much lower than what is observed in nearby dusty star-forming galaxies. This could be the result of enhanced cooling via [O i] at high-z, hotter gas and dust temperatures, and/or a reduction in the photoelectric efficiency, in which the coupling between interstellar radiation and gas heating is diminished.

Abstract
Here we discuss the jet production efficiency in a sample of 17 young radio galaxies with measured redshifts, kinematic ages, and nuclear X-ray fluxes, for which the observed luminosities of compact jets/lobes and accretion disks correspond to the same episode of AGN activity. For the targets, we analyze the available optical data, estimating the bolometric luminosities of the accretion disks L
bol, and the black hole masses; we also derive the minimum jet kinetic luminosities, P
j. With this information we investigate the distribution of our sample in the three-dimensional space of the accretion rate λ
Edd ≡ L
bol/L
Edd, the nuclear X-ray luminosity L
X considered here as a limit for the emission of the disk coronae, and P
j, expressing the latter two parameters either in the Eddington units, or in the units of the disk luminosity. We find that (i) the accretion rate λ
Edd in our sample is distributed within a narrow range λ
Edd ∼ 0.01–0.2; (ii) the normalized jet power P
j/L
Edd formally correlates with the accretion rate λ
Edd, with some saturation at the largest values λ
Edd > 0.05; (iii) the jet production efficiency

spans a range from η
jet ≲ 10−3 up to ∼0.2 at maximum, which is below the level expected for magnetically arrested disks around maximally spinning black holes; and (iv) there is a diversification in η

Abstract
This work examines the variation of interplanetary dust count rates and directionality during the first three solar encounters made by the Parker Solar Probe spacecraft, covering distances between 0.65 au (∼140 solar radii, R

S
) and 0.16 au (∼35 R

S
). Dust detections are made by the FIELDS instrument via plasma clouds, produced by impact ionization of dust grains on spacecraft surfaces and resultant spacecraft potential perturbations. Dust count rates and inferred densities are found to vary by ∼50% between the three solar encounters (∼5 months per orbit), with most of the variation concentrated below 0.23 au (∼50R

S
). Dust count rates and directionality, as well as the encounter-to-encounter variability in both quantities are found to be consistent with β-meteoroids: dust grains exiting the solar system on hyperbolic trajectories. Interpretation of the the dust count rate data and the dust directionality data independently suggest (i) that the β-meteoroid source region is more complex than preliminary models suggest, and (ii) that the primary β-meteoroid source region is approximately located between 10 and 30 solar radii from the Sun. These data offer important clues as to the location and geometry of the β-meteoroid source region, and consequently clues about the collisional and sublimation processing of interplanetary dust grains near the Sun.
Dust-depleted Inner Disks in a Large Sample of Transition Disks through Long-baseline ALMA Observations
Authors: Francis Logan , van der Marel Nienke 
Published: April 2020

Abstract
Transition disks with large inner dust cavities are thought to host massive companions. However, the disk structure inside the companion orbit and how material flows toward an actively accreting star remain unclear. We present a high-resolution continuum study of inner disks in the cavities of 38 transition disks. Measurements of the dust mass from archival Atacama Large Millimeter/Submillimeter Array observations are combined with stellar properties and spectral energy distributions to assemble a detailed picture of the inner disk. An inner dust disk is detected in 18 of 38 disks in our sample. Of the 14 resolved disks, 8 are significantly misaligned with the outer disk. The near-infrared excess is uncorrelated with the mm-dust mass of the inner disk. The size–luminosity correlation known for protoplanetary disks is recovered for the inner disks as well, consistent with radial drift. The inner disks are depleted in dust relative to the outer disk, and their dust mass is uncorrelated with the accretion rates. This is interpreted as the result of radial drift and trapping by planets in a low α (∼10−3) disk, or a failure of the α-disk model to describe angular momentum transport and accretion. The only disk in our sample with confirmed planets in the gap, PDS 70, has an inner disk with a significantly larger radius and lower inferred gas-to-dust ratio than other disks in the sample. We hypothesize that these inner disk properties and the detection of planets are due to the gap having only been opened recently by young, actively accreting planets.

Abstract
We present the ancillary data and basic physical measurements for the galaxies in the ALMA Large Program to Investigate C+ at Early Times (ALPINE) survey—the first large multiwavelength survey that aims at characterizing the gas and dust properties of 118 main-sequence galaxies at redshifts 4.4 < z < 5.9 via the measurement of [

] emission at

(64% at >3.5σ) and the surrounding far-infrared continuum in conjunction with a wealth of optical and near-infrared data. We outline in detail the spectroscopic data and selection of the galaxies as well as the ground- and space-based imaging products. In addition, we provide several basic measurements including stellar masses, star formation rates (SFR), rest-frame ultra-violet (UV) luminosities, UV continuum slopes (β), and absorption line redshifts, as well as Hα emission derived from Spitzer colors. We find that the ALPINE sample is representative of the 4 < z < 6 galaxy population selected by photometric methods and only slightly biased toward bluer colors (Δβ ∼ 0.2). Using [

] as tracer of the systemic redshift (confirmed for one galaxy at z = 4.5 out of 118 for which we obtained optical [

]λ3727Å emission), we confirm redshifted Lyα emission and blueshifted absorption lines similar to findings at lower redshifts. By stacking the rest-frame UV spectra in the [

] rest frame, we find that the absorption lines in galaxies with high specific SFR are more blueshifted, which could be indicative of stronger winds and outflows.

Background In patients treated for HCV infection, potential drug–drug interactions (DDIs) can occur among direct-acting antiviral drugs (DAAs) and comedications used. The real-life effectiveness and safety of elbasvir/grazoprevir (ELB/GZR) among co-medicated HCV patients was evaluated. Methods We prospectively evaluated consecutive patients from 15 clinical centres participating in PITER who were treated with ELB/GZR and had been followed for at least 12 weeks after treatment. Data were prospectively collected on the use of comedications (including discontinuation, dose modification and addition of drugs) and potential DDIs with DAAs. Results Of the 356 patients with at least 12-week post-treatment follow-up (median age 67, range 50–88 years), 338 (95%) achieved sustained virological response. Of these, 219 (60%) had at least one comorbidity (median 2, range 1–6); information on comedication was available for 212 of them. Of 190 comedications used, 15 (8%) drugs were modified during ELB/GZR therapy, specifically in 9 (4%) patients they were interrupted, in 2 (1%) of whom, the comedication was interrupted before the DAA therapy because of potential DDI (that is, patients treated with carbamazepine); in 12 (6%) patients the comedications were modified in terms of dosage. In 29 (14%) patients, the comedications required monitoring when used with ELB/GZR, as well as with all available DAAs. Of the 190 drugs, 27 (14%) used in 67% of patients were free of DDIs when used with ELB/GZR, whereas they required monitoring if used with other DAA regimens. Conclusions The results of this prospective study support findings that ELB/GZR is effective and safe in most treated patients.
Integrating an Online Statistics Course With a Graduate Nursing Research Course for Enhanced Learning
Authors: Theeke Laurie A. , Carpenter Roger D. 
Published: April 2020

Background:
Exploration for innovative pedagogical techniques to teach statistics led to examination of the Open and Free Courses offered through the Carnegie Mellon University Online Learning Initiative (CMU OLI). This study examined the impact of the CMU OLI statistics course on graduate nursing students' course grades and course evaluations.

Method:
This retrospective study of a hybrid course compared three teaching modalities for statistics: 1) face-to-face workshop, 2) CMU OLI course, and 3) CMU OLI course plus online discussions.

Results:

Mean grade point averages increased sequentially and significantly. Individual students' grades improved and student evaluations of instruction mean scores for critical thinking, teaching effectiveness, overall course rating, and overall learning increased significantly (
p
< .01).

Conclusion:

Future studies are needed that build knowledge of how open and free online courses can be used in nursing education to facilitate retention of content, allay statistics anxiety, and increase student motivation toward research.

WARRIORS: An Educational Initiative Improving Clinical Judgment and Safety in Medication Administration
Authors: Blazeck Alice , Faett Becky , Reid-Kelly Linda , Miller Susan , Hromadik Lora , Haines Jane 
Published: April 2020

Background:
Medication administration requires rigorous clinical reasoning leading to sound clinical judgment for positive patient outcomes. The National Council of State Boards of Nursing is implementing a clinical judgment model for the licensure examination.

Method:
To support the practice of clinical judgment in administering medication, improve patient safety, and better prepare nursing students for their licensure examination, a clinical reasoning initiative was developed to reflect the judgment needed for safe medication administration. An acronym, WARRIORS, captures the decision process exemplifying the knowledge, skills, and attitudes needed to keep patients safe.

Results:

A free training tool (
https://www.youtube.com/watch?v=YkBeGymEMuQ
) and an online electronic health record (
http://www.nursing.pitt.edu/aliceblazeckrn/
) guiding deliberate practice provide interrelated cues to support nursing students in forming a hypothesis through taking action and evaluation.

Conclusion:

This learning initiative supports nursing students' safe and accurate medication administration and can continue to be used as they move into practice.

Théorie des pouvoirs et idéologie
Authors: Augé Marc 
Published: April 2020

Issue d’une thèse d’État et publiée il y a près d’un demi-siècle, cette œuvre majeure de Marc Augé a fortement marqué l’anthropologie française. Mettant en regard les systèmes symboliques (institutions sociales, représentations du monde et de la personne, croyances et rites) de trois ethnies du Sud de la Côte d’Ivoire, Marc Augé y propose le concept « d’idéo-logique » : sorte de grammaire irréductible à toute causalité matérielle, au travers de laquelle se formulent, pour chacune d’entre elles, le possible et le pensable. Et, de manière encore plus novatrice, il montre comment les croyances en la sorcellerie se déploient au sein de cette « idéo-logique » en véritable théorie du pouvoir, c’est-à-dire en « possibilité effective d’action sur les hommes et sur les choses ». Il illustre notamment cette théorie du pouvoir par l’étude d’une communauté thérapeutique située à Bregbo, au bord de la lagune ébrié, et dirigée par le prophète Albert Atcho. Se réclamant du harrisme, ce dernier avait dès 1962 attiré la curiosité de Jean Rouch qui lui consacra le film Monsieur Albert, prophète.
By Means of Critical Theory
Authors: Strohschen Gabriele 
Published: April 2020

So-termed non-traditional adult students have become a key target for marketing efforts in higher education, and non-conventional, accelerated paths to university-issued degrees are the lure du jour in the business of selling education programs. A key ethical challenge in our profession remains how we align the education of adults according to the higher education institutions' mission statements to the education adults seek and actually receive. This chapter calls for considering the realities and possibilities of socially responsible educating when institutions are accountable to myriad stakeholders to peer at this issue through the lens of emancipatory education informed by tenets of critical theory. The argument hopes to engage the readers in problem-posing so that cross-sector, collaboratively designed education options can be considered that are contextual rather than prescriptive in nature and which align to the indigenous needs of teachers, learners, institutions, and communities.

Abstract
Leishmania major causes cutaneous leishmaniasis. An antileishmanial vaccine for humans is unavailable. In this study, we report development of two attenuated L. major strains—5ASKH-HP and LV39-HP—by continuous culture (high passage) of the corresponding virulent strains (low passage). Both avirulent strains showed similar changes in proteome profiles when analyzed by surface-enhanced laser desorption ionization mass spectrometry. Liquid chromatography–mass spectrometry and microarray characterization of 5ASKH strains revealed substantially altered gene and protein expression profiles, respectively. Both virulent and avirulent L. major strains grew comparably in culture, but the avirulent strain survived significantly less in BALB/c-derived peritoneal macrophages. Both attenuated strains failed to infect BALB/c mice and elicited IFN-γ, but not IL-4 and IL-10, responses. 5ASKH-HP parasites failed to induce significant infection even in severely immunocompromised- SCID or inducible NO synthase–, CD40-, or IL-12–deficient mice, indicating attenuation. The avirulent strain induced less IL-10, but higher IL-12, in macrophages. The avirulent strain failed to reduce CD40 relocation to the detergent-resistant membrane domain and to inhibit CD40-induced phosphorylation of the kinases Lyn and protein kinase C-β and MAPKs MKK-3/6 and p38MAPK or to upregulate MEK-1/2 and ERK-1/2 in BALB/c-derived peritoneal macrophages. The virulent and the avirulent strains reciprocally modulated CD40-induced Ras-mediated signaling through PI-3K and Raf-1. Avirulent 5ASKH-primed BALB/c mice were protected against virulent L. major challenge infection. The loss of virulence accompanied by substantially altered proteome profiles and the elicitation of host-protective immune responses indicate plausibly irreversible attenuation of the L. major strain and its potential use as a vaccine strain.

Com a facilidade de propagação de conteúdos através das redes sociais digitais, muitas produções populares são lançadas diariamente por meio de páginas e canais específicos. Esses ao despertar o olhar das instâncias midiáticas e mercadológicas são apropriados e, ao mesmo tempo, lhes são atribuídos outras intenções ou sentidos. Desse modo, o presente artigo visa identificar se há uma interferência significativa das intenções mercadológicas e midiáticas nos canais mantidos no YouTube pelo Dream Team do Passinho? Para isso, utilizou-se da observação encoberta não participante, ou seja, não há por parte do pesquisador qualquer ação de proximidade, juntamente com o mapeamento de dois canais mantidos pelo Dream Team do Passinho no YouTube. A partir dessa estrutura, chegou-se a números expressivos que diferenciam um canal do outro, apontando para uma interferência significativa na intensidade da visibilidade adquirida pelo grupo no momento em que são entremeadas intenções mercadológicas e midiáticas. As quais são responsáveis por ampliar a dinâmica de estabelecimento de relações sociais e midiáticas, atribuindo ao grupo sentidos antes não existentes como, por exemplo, a celebrização.
A adoção de estratégias cooperativas por micro e pequenas empresas de consultoria como ferramenta de vantagem competitiva
Authors: Sanches Ji Yoon Lee , Zilber Moisés Ari 
Published: April 2020

This paper aims to analyze the adoption of cooperative strategies by micro and small consulting firms as a competitive advantage tool.Although the literature usually relates the examples of cooperation strategies to cases of large companies, the practice has been usual among small organizations. Increased competition and the need to survive in a competitive environment have been identified as the main causes of cooperation between small companies, who see in cooperative strategies possibilities to add value to their services (BORTOLASO; VERSCHOORE; ANTUNES, 2012; DOZ; HAMEL 1998; CHILD; FAULKNER, TALLMAN, 2005). Through a qualitative, descriptive and interpretative study it aims to relate the motivation in adopting such cooperative strategies to various economic and management lenses that provide theoretical support to the subject. The results showed that cooperative strategies practiced by micro and small consulting firms have enabled competitive advantage over companies that do not adopt them, mitigating the competitive vulnerability and adding more value to their activities.

This article starts from the examination of the historical conceptions of work and its meaning in the life of organization managers. As the interest in work, well-being and happiness increase, also increase in the same proportion the need to elaborate an appropriate taxonomy of these concepts, starting from its meaning and characteristics attributed to the work. These scores help to determine how work juxtaposes the happiness and well-being constructs. A taxonomy and its indicators help determine how juxtaposes the happiness and well being constructs. Subsidizing the theoretical studies, a field research was done with 249 executive managers of the Rio-São Paulo axis. The statistical treatment adopted was an exploratory factorial analysis. The research finds revealed that the pace of activity imposed on managers is closed to the original meaning of the term, suffering. It is assessed - not generalizable - that happiness, well-being and quality of life at work, are not isolated constructs, but are aligned with the aspirations of the executives, understanding that, in order to have life outside of work, there must be life in it.
