Setting the Stage for Cosmic Chronometers. II. Impact of Stellar Population Synthesis Models Systematics and Full Covariance Matrix
Authors: Moresco Michele , Jimenez Raul , Verde Licia , Cimatti Andrea , Pozzetti Lucia
Published: July 2020

The evolution of differential ages of passive galaxies at different redshifts (cosmic chronometers) has been proved to be a method potentially able to constrain the Hubble parameter in a cosmology-independent way, but the systematic uncertainties must be carefully evaluated. In this paper, we compute the contribution to the full covariance matrix of systematic uncertainties due to the choice of initial mass function, stellar library, and metallicity, exploring a variety of stellar population synthesis models. Through simulations in the redshift range 0 < z < 1.5, we find that the choice of the stellar population synthesis model dominates the total error budget on H(z), with contributions at a level of ∼4.5%, discarding the most discordant model. The contribution due to the choice of initial mass function is <0.5%, while that due to the stellar library is ∼6.6%, on average. We also assess the impact of an uncertainty in the stellar metallicity determination, finding that an error of ∼10% (5%) on the stellar metallicity propagates to a 9% (4%) error on H(z). These results are used to provide the combined contribution of these systematic effects on the error budget. For current H(z) measurements, where the uncertainties due to metallicity and star formation history were already included, we show that, using the more modern stellar libraries, the additional systematic uncertainty is between 5.4% (at z = 0.2) and 2.3% (at z = 1.5). To reach the goal of keeping the systematic error budget below the 1% level, we discuss the efforts needed to obtain higher resolution and signal-to-noise spectra and improvements in the modeling of stellar population synthesis.
Geometric Support for Dark Matter by an Unaligned Einstein Ring in A3827

Published: July 2020

The nondetection of dark matter (DM) particles in increasingly stringent laboratory searches has encouraged alternative gravity theories where gravity is sourced only from visible matter. Here, we consider whether such theories can pass a two-dimensional test posed by gravitational lensing—to reproduce a particularly detailed Einstein ring in the core of the galaxy cluster A3827. We find that when we require the lensing mass distribution to strictly follow the shape (ellipticity and position angle) of the light distribution of cluster member galaxies, intracluster stars, and the X-ray emitting intracluster medium, we cannot reproduce the Einstein ring, despite allowing the mass-to-light ratios of these visible components to freely vary with radius to mimic alternative gravity theories. Alternatively, we show that the detailed features of the Einstein ring are accurately reproduced by allowing a smooth, freely oriented DM halo in the lens model, with relatively small contributions from the visible components at a level consistent with their observed brightnesses. This dominant DM component is constrained to have the same orientation as the light from the intracluster stars, indicating that the intracluster stars trace the gravitational potential of this component. The Einstein ring of A3827 therefore presents a new challenge for alternative gravity theories: not only must such theories find agreement between the total lensing mass and visible mass, but they must also find agreement between the projected sky distribution of the lensing mass and that of the visible matter, a more stringent test than has hitherto been posed by lensing data.

Some lost worlds of Eric Hobsbawm: interviews with a communist historian: 1990-2001
Authors: Howe Antony
Published: July 2020

By common consent one of the finest historians of his generation, Eric Hobsbawm was also a longstanding member of the British Communist Party. In particular, his formative years as a historian spanned the period from the popular front communism of the 1930s to the post-war Communist
Party Historians' Group. The background and activities of the Historians' Group have been described many times, including by Hobsbawm himself. Nevertheless, in these interviews recorded between 1990 and 2001 Hobsbawm opened up regarding the role of key networks and personalities that did not
always figure in accounts like his autobiography Interesting Times. Notably among them are Dona Torr and John Morris, the historian of the classical world with whom Hobsbawm launched the journal Past and Present at the height of the Cold War.
Populism
Authors: Featherstone David , Karaliotas Lazaros
Published: July 2020

Populism refers to forms of politics that put 'the people' at their centre, but the way 'the people' is understood varies widely. Questions of left populism have gained significant traction and engagement in the last decade - and this is a key focus of this article. While recognising
the importance of Ernesto Laclau's analysis in On Populist Reason, the authors argue that his work is hindered by an overly formalist account of the political. Stuart Hall's writings on Thatcherism offer a more contextual and situated engagement with particular populist strategies,
and have continuing relevance for understanding right-wing populism. Podemos in Spain and Syriza in Greece offer actually existing experiences of left populism. We discuss three limitations in their strategies: their 'nationed' narratives of the crisis; the relationship between the parties'
leadership and grassroots politics; and the nature of their engagement with internationalist political projects. Part of the critical terms series
The question of progressive agency
Authors: Rustin Michael
Published: July 2020

This article revisits debates about agency: what and where are the forces and agents that might bring about change? In the past liberals and socialists broadly shared a belief in social enlightenment and progress, but liberals believed that this could be achieved gradually, through
education, while Marxists believed that self-organisation by the working class was the way forward. A third, more recent, approach argues that changes in information technology are making it possible for society to shift from hierarchical to lateral patterns of connection. These three different
approaches to agency are critically discussed. Among the thinkers discussed are Karl Marx, Raymond Williams, Eric Hobsbawm, Robin Murray, Manuel Castells, Michael Hardt and Antonio Negri. The rethinking and renewal of institutions that modern societies now need calls for deep engagement with
these issues, and both 'new' and 'old' conceptions of agency are relevant to this task. Part of the critical terms series

Welfare imaginaries at the interregnum
Authors: Jensen Tracey , Allen Kim , de Benedictis Sara , Garthwaite Kayleigh , Patrick Ruth
Published: July 2020

This article brings together reflections from the recent seminar series, Welfare Imaginaries, and explores the ways that 'welfare' has been and can be narrated, constructed and understood. There is an urgent need to consider alternative, and more creative, imaginings of the welfare
state, particularly at a time of intensifying neoliberalism and austerity measures, a hardening of attitudes towards welfare, and divisive rhetoric centred around deservingness. Both research and the lived experiences of austerity have shown the disproportionate impacts of welfare reforms
on those already living with significant hardship. In creatively rethinking and reshaping welfare, the authors argue that those with direct experience of poverty, and thus most affected by welfare reform, should be a significant part of the conversation; and they also consider different ways
of crafting welfare imaginaries that are inclusive, fair and socially just.

Published: July 2020

The coexistence of ferromagnetism and paramagnetism of T’-Pr2-xCexCuO4+α-δ (T’-PCCO) nanoparticles with x = 0, and 0.10 have been studied intensively in the normal state. All samples were synthesized by a chemically dissolved method using HNO3 as a dissolving agent. The calcination process was performed at 1000°C for 15 h in air and followed by reduction annealing at 700°C in argon atmosphere for 10 h. All samples were first characterized by an x-ray diffraction (XRD) measureemnts followed by Rietveld and Maximum Entropy Method (MEM) analyseis. The result confirms the Ce-dependence and reduction annealing effect on the electron density at around the Cu site. The magnetic characterization was performed by using vibration sample magnetometer (VSM) indicating weak ferromagnetic properties at x = 0 and dominant paramagnetic properties at x = 0.10 at room temperature. Moreover, the weak ferromagnetic feature seems to remain after the annealing process. This signifies the coexist of weak ferromagnetism and paramagnetism at the normal state due to a number of oxygen vacancies in the crystal structure.

Magneto-impedance ratio of the multilayer [NiFe/Cu)]N study by the number of multilayer. The both sample films of NiFe and Cu are fabricated by electrodeposition methods on a Cu-patterned substrate. The characteristic of magneto-impedance (MI) is performed at room temperature. Magneto-impedance are modified by varying N times (2, 4, 6 and 8) and the measurements frequency. The result show that the typical symetry of the magneto-impedance curve. Then the magneto-impedance (MI) ratio increases with the increase of frequency and N number layers. The increase of the magnetic permeability should address the increase of the MI ratio. Finally, the highest magneto-impedance ratio of 13.79 is obtained for [NiFe (200)/Cu (25)]8 at frequency 100 kHz.

Published: July 2020

The NiCexFe2-xO4 polycrystalline spinel compound with composition x = 0.005, 0.010, 0.015, and 0.02 was synthesized by the solid reaction method using the high energy milling (HEM) apparatus. Measurement of the neutron diffraction patterns is carried out at room temperature using a high resolution powder neutron diffractometer (HRPD), wavelength λ = 1.8213 Å. The measured neutron diffraction data were analyzed by the Rietveld method utilizing the FullProf analysis code. The results of the neutron diffraction pattern refinement revealed that the sample has a cubic symmetry, the Fd-3m space group, mixed inverse spinel structure, A-site occupied by cation Fe3+, Ni2+, dan Ce3+. Whereas the B-site is only occupied by Fe3+ and Ni2+. The mole fraction of Fe3+ at the B-site is greater than the Fe3+ mole fraction at the A-site, whereas the mole fraction of Ni2+ at the B-site is smaller than the mole fraction of Ni2+ at the B-site. As a result of Ce3+ doping, oxygen position parameters increase, magnetic moments on B-site, and the net magnetic moments decrease. Ni2+ concentrations at the A-site and the B-site were not affected by the amount of Ce3+ substitutions. Without substitution and after Ce3+ substitution, the O-site occupancy factor is still oxygen deficient.

In this study, effect of La substitution on the microstructure, magnetic properties and microwave absorption characteristics of Ba1-xLaxFe12O19 (x=0, 0.1, 0.2, 0.3, 0.5, 0.7) is reported. The samples were synthesized through mechanical alloying and solid reaction a temperature 1200 °C for 2 hours. A single-phase material occurred only at x = 0 and 0.1. Additional second phases were existing in all samples with x ≥ 0.2 which led to multi-phase materials. The single phase (x = 0 and 0.1) has a relatively uniform particle size distribution with a mean crystallite size 138 nm. Additional phases of respectively Fe2O3 and LaFe2O3 were identified in all samples with x ≥ 0.2. Effect of La substitution is to decrease the magneto crystalline anisotropy constant and the saturation magnetization. The latter is due to a decrease in mass fraction of the main magnetic phase. All Ba1-xLaxFe12O19 samples have superior microwave characteristics which able to absorb more than 99 % the incoming electromagnetic wave entering the material. The absorption bandwidth is found relatively wide within the frequency range 8-12 GHz.
Microstructure and Microwave Absorption Characteristics of BaTiO3-CoFe2O4 Composites
Authors: Zainal Yuda Bakti , Dedi  , Manaf Azwar
Published: July 2020

Magnetic and dielectric phases like CoFe2O4 and BaTiO3 are both intrinsically capable of absorbing electromagnetic waves. The characteristics of the two phases in a composite structure to obtain the combined effect of the existence of phases as composite components have been investigated. Observation of the microstructure of composites with the composition (1-x)BaTiO3-(x)CoFe2O4 has shown the compact structure of composite sample with an increased the mass density with increasing value of x. No changes in lattice constant of each phase in the composite structure. This ensures that no complete or partial substitution between the ions of each phase has occurred. However, the presence of a material phase in the composite structure influenced the crystallite growth behavior of each phase. The mean crystallite size of the two phases tends to increase, but grew with a different rate. The saturation magnetization value of the composite samples is composition dependent. The value of remanent magnetization and coercivity increases with increasing values of x. All composite samples based on the results of data evaluation data taken by a vector network analyzer (VNA) in X-band frequency, shows the ability to absorb electromagnetic waves in all X-band frequencies. Composite composition determined the peak frequency that gives the maximum reflection loss value. The largest maximum reflection loss value is-40 dB occurring at a frequency of 10.98 GHz from samples with a composition x = 0.5. In conclusion, the composite of CoFe2O4/BaTiO3 system composite can be a promising candidate for electromagnetic wave dampers when the composite is properly designed.

Published: July 2020

A bonded permanent magnet of Barium hexa Ferrite has been made using powder BaFe12O19 (commercial ferrite) and a polymer of bakelite powder as binder. The composition of bakelite was varried 5% wt. The preparation of sample was begun with mass weighing for each material, then mixed together using ball mill for 1, 6 and 12 hours and using aquades as milling media. The mixed powder is dried in an oven at 110 °C for 4 hours, then the particle size distribution was measured. After that, the dried sample powder was pressed to form a pellet at pressure 40 MPa and temperature about 160 °C for 20 minutes. The characterization of sample pellet was done such as measurement of bulk density, hardness , magnetic properties using VSM and anylisis of microstructure using SEM. The results of the characterization show that the density and magnetic properties tend to increase with increasing of milling time, where the highest density, hardness and highest magnetic properties are achieved at sample with milling time for 12 hours. The value of magnetic properties at this condition are flux magnetic of 530 Gauss, remenance of 3100 Gauss, coercivity of 1,10 kOe.

Authors: Vitharana Asiri D.
Published: July 2020

The study explores the importance of Solid Waste Management (SWM) for Sound Environmental Development (SED) in Hambantota Municipal Council (HMC) area in Sri Lanka. Data for the study was collected using integrated research tools including Semi-structured interviews, self-completion questionnaires, focus group discussions and non-participatory observations. The ‘Random Sampling Method’ was used to select households and business population while ‘Purposive Sampling’ was used to select respondents for the interviews and focus groups. The study revealed that lack of awareness, little synergy between local authorities and the community and challenges of limited resources, facilities and funds and illegal dumping for proper SWM process were the dominant problems in SWM. In this regard, the paper suggests an integrated SWM process, with awareness programmes and cooperation between authorities and community for the process. Implementing SWM in to Development policies for Sustainable Development, has been further suggested.
Unemployment, official economy and the dimension of the shadow economy: an empirical analysis for Sri Lanka using SEM approach
Authors: Samaranayake D. I. J. , Dayarathna-Banda O. G.
Published: July 2020

This study attempts to estimate the share of Sri Lankan shadow economic activities as a percentage of official estimates, while revolving the wheel of non-clarified zones and market functions through overstepping the traditional official estimates. The methodology involves the estimation of structural models to analyse a set of causes of the shadow economy and its influence upon a series of indicators. The study introduces three Multiple Indicator Multiple Cause (MIMIC) models namely MIMIC 5-1-2a, MIMIC 4-1-2b and MIMIC 3-1-3a. The benchmark calculations for each model derives a series of average values for the Sri Lankan shadow economy (SE) in the period from 1990 to2012. Estimated data in model MIMIC 5-1-2a suggests to evidence that the average size of shadow economy in the country is ranging between 91% and 32% in the period from 1990 to 2012 with a decreasing trend. By contrast, calculations for MIMIC 4-1-2b and MIMIC 3-1-3a demonstrate a size of 14% and 52% with an increasing trend respectively. In-depth analysis further reveals the facts that effect the share of tax on goods and services to the government revenue and the level of public employments tend to undermine the increasing pattern of shadow economy. Since the unemployment rate and private employment is playing a charismatic role in the economy, shadow economy tends to increase. Eradicating the workplace enforcement crisis and underemployment issues may hinder the increasing pattern. The results from re-examination of Okun’s law supports for the idea that, less interdependence of the growth of shadow economy and official economy and a parallel growth with shifting stages in market functions.

ALL'INDOMANI DEI PATTI LATERANENSI (1929) | LE REAZIONI DEI CATTOLICI ITALIANI
Authors: Zambarbieri Annibale
Published: July 2020

After an overview of the Italian Catholics expectations towards the solution of the Questione Romana, this study carries out a review of the reactions to the signing of the Patti Lateranensi from the clergy and laity. We will see the endorsements of many, who saw in the event the end of years of contrasts between Church and State, both the achievement of an agreement with the fascist regime. At the same time, not the reservations and disappointments were lacking, even though they were minority of exponents of the dissolved Partito Popolare, which saw in those arrangements an undue support to the political establishment; others predicted changes in the programs of the Catholic organizations, directing them to form culturally and spiritually especially the élite members of the laity. After Mussolini’s speeches in the Camera dei deputati and in the Senato, on the procedures for the ratification of the Patti, the claim of the State’s superiority over the Church were viewed with concern. The tensions were loosened, inaugurating a consensus cooperation, but not free of momentary friction. However, the regime’s attempt to configure its own religion had to fade away in the face of the persistence of convictions and long-established cultic practices.

Published: July 2020

Introduction:

The “biological” symptoms in some depressive illnesses are loss of sleep, appetite and weight, psychomotor changes, decreased libido, etc., Those in the remaining forms of depression include anxiety, phobias, and obsessional symptoms. These two groups of symptoms constitute melancholic and nonmelancholic depression, respectively. This research aimed at studying the clinical, cognitive, and sociodemographic profiles in melancholic and nonmelancholic depression.

Methods:

This cross-sectional, observational study was conducted in a tertiary care teaching hospital among 60 in-patients over a period of 1 year following clearance from the Institutional Ethics Committee. Among the total 60 participants enrolled, 30 met criteria for depression with melancholic features and 30 had depression without melancholic features according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Patients were administered a specialized pro forma to record the demographic, medical, psychiatric, and other relevant clinical data. Hamilton's Depression Rating Scale was used for assessing severity of depression; Clinical Outcomes in Routine Evaluation (CORE) Questionnaire was used to assess melancholic features; and cognitive assessment was done using Mini-Mental State Examination (MMSE) and semantic verbal fluency test. Suicide ideation was assessed using the Modified Suicide Ideation Scale.

Results:

Our study showed a statistically significant difference in CORE score, MMSE, semantic verbal fluency, and Modified Suicide Ideation Sscale scores, all with P < 0.001 in the melancholic group compared to nonmelancholic group; however, Hamilton depression scores were not significantly different between them with P < 0.264.

Conclusion:

Melancholic depression differs from nonmelancholic depression in various clinical and cognitive aspects, with more cognitive deficits and suicide ideation in the melancholic group.
Triggering Altruism Increases the Willingness to Get Vaccinated Against COVID-19
Authors: Rieger Marc Oliver
Published: July 2020

Introduction:

Once a vaccine against COVID-19 is available, the question of how to convince as many people as possible to get vaccinated will arise. We test three different strategies to reach this goal: two selfish motivations (highlighting personal survival risk or the inconveniences in the event of getting infected) and altruism (reducing the danger for individuals who cannot be vaccinated or remain vulnerable even after getting vaccinated).

Methods:

We conduct an online experiment with N = 303 subjects (64% female, 79% university students, average age 26 years) with the three aforementioned treatments and compare the treatment effects on vaccination willingness with the baseline.

Results:

Results suggest a positive effect of all treatments, but the treatment where reducing the danger for individuals who cannot be vaccinated was highlighted was by far the most effective.

Conclusion:

This result implies that this rarely discussed aspect should be given more attention to increase the willingness to get vaccinated against COVID-19.

Published: July 2020

Studies of the bycatch associated to the shrimp trawling fishery in the Pacific coast of Costa Rica do not assess small organisms (< 10 cm TL) and non-dominant species (< 0.1% of total catch). There is a void in assessing the maintenance of the ecology and ecosystem on which the fishery depends. Furthermore, the Constitutional Court of Costa Rica prohibited the renewal of existing and the issuing of new shrimp bottom-trawl licenses, indicating the necessity of more scientific information on the impacts of this fishery. We present the results of a 23-month study of the shrimp bottom-trawl fishery performed between 50 and 350 m deep in the Pacific coast of Costa Rica. A total of 109 hermit crabs were collected (six species and two families). Paguristes cf. holmesi was the most common species. Zone II presented the highest species richness and abundance. Most specimens (81.8 %) were caught in shallower waters (50-149 m). More than 45% of the trawls presented hermit crabs. It is imperative to further assess the trawling effects on non-commercial benthic fauna and changes on predator-prey relationships before issuing new shrimp licenses

Patagonian octopus (Octopus tehuelchus) is a species that holds an artisanal fishery in the northern area of the Argentine Patagonian coast and has a potential for aquaculture development. This work aimed to characterize the mating behavior of four pairs of Patagonian octopuses under laboratory conditions. Results showed that this species has a complex reproductive behavior. Remarkably, female remained inside her shelter during pre-copula, copulation and intercourse events. Male and female faced by the oral face during sexual intercourse, which lasted 3 to 5 min. The observations will contribute to the better management of the reproductive specimens of the species in captivity.

Published: July 2020

Nesse século XXI, impulsionados pela disseminação do acesso à internet, ocorreram avanços tecnológicos exponenciais. Nesse contexto, as operações comerciais e, simultaneamente, o comércio eletrônico contribuíram de forma decisiva para mudanças organizacionais. Assim, o objetivo deste estudo é compreender o processo de serviço ao cliente a partir de uma estratégia de marketplace. Para isso, fez-se um estudo de caso, com questionário préestruturado, com uma empresa de comércio eletrônico, destacando-se as decisões ao longo do processo transacional. Diante dos apontamentos, comprovou-se que a estratégia de marketplace está alinhada à definição de que a qualidade no comércio eletrônico é um constructo multidimensional. O artigo tem como limitação o estudo de caso único, que contemplou exclusivamente a perspectiva da empresa focal da cadeia de suprimentos. Os estudos futuros poderão abordar esse tema ampliando a amostra de empresas para a análise – tanto a montante quanto a jusante da empresa focal – e estendendo a pesquisa aos grandes players do marketplace. Destaca-se, também, a contribuição social, tendo em vista as possibilidades para pequenas organizações acessarem mercados com barreiras por questões financeiras, logísticas ou de marketing.
Determination and climatology of the diurnal cycle of the atmospheric mixing layer height over Beijing 2013–2018: lidar measurements and implications for air pollution

Abstract. The atmospheric mixing layer height (MLH) determines the
space in which pollutants diffuse and is thus conducive to the estimation of
the pollutant concentration near the surface. The study evaluates the
capability of lidar to describe the evolution of the atmospheric mixing layer
and then presents a long-term observed climatology of the MLH diurnal cycle.
Detection of the mixing layer heights (MLHL and MLHL′) using
the wavelet method based on lidar observations was conducted from January 2013 to
December 2018 in the Beijing urban area. The two dataset results are
compared with radiosonde as case studies and statistical forms. MLHL
shows good performance in calculating the convective layer height in the daytime
and the residual layer height at night. While MLHL′ has the potential to describe the stable layer height at night, the performance is limited due to the high range gate of lidar. A nearly 6-year
climatology for the diurnal cycle of the MLH is calculated for convective and stable
conditions using the dataset of MLHL from lidar. The daily maximum
MLHL characteristics of seasonal change in Beijing indicate that it is
low in winter (1.404±0.751 km) and autumn (1.445±0.837 km)
and high in spring (1.647±0.754 km) and summer (1.526±0.581 km). A significant phenomenon is found from 2014 to 2018: the magnitude
of the diurnal cycle of MLHL increases year by year, with peak values of
1.291±0.646 km, 1.435±0.755 km, 1.577±0.739 km,
1.597±0.701 km and 1.629±0.751 km, respectively. It may
partly benefit from the improvement of air quality. As to converting the
column optical depth to surface pollution, the calculated PM2.5
using MLHL data from lidar shows better accuracy than that from
radiosonde compared with observational PM2.5. Additionally, the
accuracy of calculated PM2.5 using MLHL shows a diurnal cycle in
the daytime, with the peak at 14:00 LST. The study provides a
significant dataset of MLHL based on measurements and could be an
effective reference for atmospheric models of surface air pollution
calculation and analysis.
