Tunable charge density wave in a lateral black/blue phosphorene heterostructure: A first-principles calculation

We reveal a one-dimensional (1D) charge density wave (CDW) at the lateral interface of black/blue phosphorene heterostructure (BBPH). This emerging CDW is induced by Fermi surface nesting and characterized by dimerization of unsaturated P atoms at the boundary. Accordingly, lattice distortion and band-gap opening simultaneously occur in the BBPH with prominently lowered total energy from metallic structure (MS) to the CDW phase. Due to the quantum confinement effect, the band gap increases as the heterostructure width reduces. Under an accessible electron doping level of $\ensuremath{\sim}{10}^{14}\phantom{\rule{0.16em}{0ex}}\mathrm{c}{\mathrm{m}}^{\ensuremath{-}2}$, the relative stability between the CDW phase and the MS can be flipped because of their different electron occupation distributions and enhanced electrostatic repulsion at the boundary. In addition, this junction boundary provides a good platform to study the 1D Su-Schrieffer-Heeger (SSH) model. We predict that an SSH-type electron soliton would emerge when there is a dimerization fault, which carries a topologically protected unpaired electron, and can migrate along the boundary with a tunable energy barrier.

Occupational structure of bearers of Jewish rabbinical, occupational and generic surnames

We study choice of profession in three groups of Russian-speaking Jewish families with different occupational distributions of the ancestors. This study continues exploration of the persistence of social status of families over centuries that was initiated in recent years. It was found previously that in some cases professions remain associated with the same surnames for many generations. Here the studied groups are defined by a class of the surname of individuals composing them. The class serves as a label that indicates a professional bias of the ancestors of the individual. One group are the bearers of the class of surnames which were used by rabbinical dynasties. The other group is constituted by occupational surnames, mostly connected to crafts. Finally, the last group are generic Jewish names defined as surnames belonging to neither of the above groups. We use the self-collected database that consists of 858 and 1057 of the first two groups, respectively, and 7471 generic Jewish surnames. The statistics of the database are those of individuals drawn at random from the considered groups. We determine shares of members of the groups working in a given type of occupations together with the confidence interval. The occupational type’s definition agrees with International Standard Classification of Occupations. It is demonstrated that there is a statistically significant difference in the occupational structure of the three groups that holds beyond the uncertainty allowed by 95% confidence interval. We quantify the difference with a numerical measure of the overlap of professional preferences of different groups. We conclude that in our study the occupational bias of different population groups is preserved at least for two centuries that passed since the considered surnames appeared.

Application effect of primary trauma treatment teaching mode in cardiopulmonary resuscitation training of special occupation in mountainous area of Southern Ningxia

To explore the application value of primary trauma treatment (PTC) teaching mode in special professional cardiopulmonary resuscitation (CPR) guide training. Cluster sampling method was adopted, and the residents' committee selected special occupation population from every town/sub-district office in the southern mountainous area of Ningxia Hui Autonomous Region for CPR training. A monthly session was held from January to December 2019, with personnel trained by traditional operation teaching and individual practice method from January to June 2019 as the control group and personnel trained by PTC teaching mode from July to December 2019 as the observation group. The two groups of trainers, training objectives and assessment standards were consistent. Questionnaire survey was conducted at the beginning and end of each training period, including the degree of mastery of first-aid knowledge and skills and the level of self-efficacy, etc., to evaluate the training effect. There were 503 trainees in each group, and there was no significant difference in gender, age, education and occupation distribution between the two groups. There was no significant difference in the first aid principles, CPR skill level and self-efficacy between the two groups before the training. The first aid principle, CPR skills level and self-efficacy of the two groups after training were all improved, and the principle of first aid and CPR skills level in the observation group was obviously higher than that in the control group (first aid related concepts: 4.39±0.76 vs. 3.87±0.89, gold life-saving time: 5.71±0.49 vs. 4.53±0.62, the meaning of the first witnesses: 5.33±0.82 vs. 4.18±0.78, cardiac, respiratory cardiac arrest in the judgment: 5.12±0.73 vs. 4.07±0.73, CPR skills: 5.29±0.64 vs. 4.15±0.71, all P < 0.05). The self-efficacy score of the observation group was significantly higher than that of the control group (emergency attitude: 18.17±1.24 vs. 17.35±1.25, self-efficacy: 13.56±1.54 vs. 11.35±1.26, behavioral intention: 9.56±0.84 vs. 8.92±0.95, all P < 0.05). The application of PTC teaching mode in the training of CPR guidelines for special professions has significant effects, which can effectively help special professions to master CPR knowledge and skills, and has promotion value.

Globalization, Job Tasks and the Demand for Different Occupations

Globalization has increased in recent decades, resulting in structural changes of production and labor demand. This paper examines how the increased global engagement of firms affects the structure of the workforce. We find that the aggregate distribution of occupations in Sweden has become more skilled between 1997 and 2013. Moreover, firms with a high degree of international orientation have a relatively skilled distribution of occupations and firms with low international orientation have a relatively unskilled distribution of occupations. High- and low-skilled occupations have increased in importance whereas middle-skilled occupations have declined with a resulting job polarization. We also discuss and analyze the role played by new technology and automatization.

The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: exploring the halo occupation distribution model for emission line galaxies

ABSTRACT We study the modelling of the halo occupation distribution (HOD) for the eBOSS DR16 emission line galaxies (ELGs). Motivated by previous theoretical and observational studies, we consider different physical effects that can change how ELGs populate haloes. We explore the shape of the average HOD, the fraction of satellite galaxies, their probability distribution function (PDF), and their density and velocity profiles. Our baseline HOD shape was fitted to a semi-analytical model of galaxy formation and evolution, with a decaying occupation of central ELGs at high halo masses. We consider Poisson and sub/super-Poissonian PDFs for satellite assignment. We model both Navarro–Frenk–White and particle profiles for satellite positions, also allowing for decreased concentrations. We model velocities with the virial theorem and particle velocity distributions. Additionally, we introduce a velocity bias and a net infall velocity. We study how these choices impact the clustering statistics while keeping the number density and bias fixed to that from eBOSS ELGs. The projected correlation function, wp, captures most of the effects from the PDF and satellites profile. The quadrupole, ξ2, captures most of the effects coming from the velocity profile. We find that the impact of the mean HOD shape is subdominant relative to the rest of choices. We fit the clustering of the eBOSS DR16 ELG data under different combinations of the above assumptions. The catalogues presented here have been analysed in companion papers, showing that eBOSS RSD+BAO measurements are insensitive to the details of galaxy physics considered here. These catalogues are made publicly available.

OCCUPATIONAL EMPLOYMENT PATTERN AND FUNCTIONAL SPECIALIZATION IN THE BRAZILIAN CITIES

The objective of this paper is to analyze the location pattern of occupational employment in Brazil in 2010, as well as to test of the hypothesis of functional specialization according to the size of Brazilian municipalities and if this specialization changes according to the industrial sector. For this, we used the local Moran’s I and the Locational Quotient. The results show that there is significant spatial heterogeneity in the distribution of occupations in the industrial sector in Brazilian municipalities. In addition, the hypothesis of functional specialization in function of the size of the cities and the importance to analyze each sector separately was confirmed. As not all sectors present the same pattern of functional specialization, especially for occupations related to management and R&D activities. These results provide additional information to understand sectoral and occupational structure of regional economies, factors that have a direct influence in the regional growth and development.

The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: N-body mock challenge for the quasar sample

ABSTRACT The growth rate and expansion history of the Universe can be measured from large galaxy redshift surveys using the Alcock–Paczynski effect. We validate the Redshift Space Distortion models used in the final analysis of the Sloan Digital Sky Survey (SDSS) extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 16 quasar clustering sample, in configuration and Fourier space, using a series of halo occupation distribution mock catalogues generated using the OuterRim N-body simulation. We test three models on a series of non-blind mocks, in the OuterRim cosmology, and blind mocks, which have been rescaled to new cosmologies, and investigate the effects of redshift smearing and catastrophic redshifts. We find that for the non-blind mocks, the models are able to recover fσ8 to within 3 per cent and α∥ and α⊥ to within 1 per cent. The scatter in the measurements is larger for the blind mocks, due to the assumption of an incorrect fiducial cosmology. From this mock challenge, we find that all three models perform well, with similar systematic errors on fσ8, α∥, and α⊥ at the level of $\sigma _{f\sigma _8}=0.013$, $\sigma _{\alpha _\parallel }=0.012$, and $\sigma _{\alpha _\bot }=0.008$. The systematic error on the combined consensus is $\sigma _{f\sigma _8}=0.011$, $\sigma _{\alpha _\parallel }=0.008$, and $\sigma _{\alpha _\bot }=0.005$, which is used in the final DR16 analysis. For baryon acoustic oscillation fits in configuration and Fourier space, we take conservative systematic errors of $\sigma _{\alpha _\parallel }=0.010$ and $\sigma _{\alpha _\bot }=0.007$.

Early evidence of the impacts of COVID-19 on minority unemployment

This paper provides early evidence of the impacts of the COVID-19 pandemic on minority unemployment in the United States. In the first month following March adoptions of social distancing measures by states, unemployment rose to 14.5% but a much higher 24.4% when we correct for potential data misclassification noted by the BLS. Using the official definition, unemployment in April 2020 among African-Americans rose by less than what would have been anticipated (to 16.6%) based on previous recessions, and the long-term ordering of unemployment across racial/ethnic groups was altered with Latinx unemployment (18.2%) rising for the first time to the highest among major groups. Difference-in-difference estimates confirm that the initial gap in unemployment between whites and blacks in April was not different than in periods prior to the pandemic; however, the racial gap expanded as unemployment for whites declined in the next two months but was largely stagnant for blacks. The initially large gap in unemployment between whites and Latinx in April was sustained in May and June as unemployment declined similarly for both groups. Non-linear decompositions show a favorable industry distribution partly protected black employment during the early stages of the pandemic, but that an unfavorable occupational distribution and lower average skills levels placed them at higher risk of job losses. An unfavorable occupational distribution and lower skills contributed to a sharply widened Latinx-white unemployment gap that moderated over time as rehiring occurred. These findings of disproportionate impacts on minority unemployment raise important concerns regarding lost earnings and wealth, and longer-term consequences of the pandemic on racial inequality in the United States.

Earnings distributions of scalable vs. non-scalable occupations

It has been suggested that occupations where one is paid by the hour are not scalable, while scalable occupations allow one to make more money without an equivalent increase in labor and time. Non-scalable occupations are expected to have low income variance, whereas scalable ones show large income inequalities. This study examines the evidence for this suggested categorizing using personal earnings microdata for twelve candidate occupations of both types, scalable and not. We find the upper tails of all distributions decay as power laws. Moreover, we cannot reject the suggested categorizing for earnings above medians.

Accurate emulator for the redshift-space power spectrum of dark matter halos and its application to galaxy power spectrum

An accurate theoretical template of the redshift-space galaxy power spectrum, if applicable out to nonlinear scales, enables us to extract more stringent and robust constraints on cosmological parameters from the measured galaxy clustering. In this work, we develop a simulation-based template, so-called emulator, for the redshift-space power spectrum of dark matter halos. Using the redshift-space halo power spectra measured from the Dark Quest $N$-body simulation suite that covers 101 flat-geometry $w$CDM cosmologies around the Planck $\Lambda$CDM model, we feed these data into a feed-forward neural network to build the fast and accurate emulation of the power spectrum from the linear to nonlinear scales up to $k \simeq 0.6 \,h \,{\rm Mpc}^{-1}$. Our emulator achieves about 1% and 5% fractional accuracies in predicting the monopole and quadrupole moments of the power spectrum, respectively, for halos of $\sim 10^{13}h^{-1}M_\odot$ that correspond to host halos of the SDSS LOWZ- and CMASS-like galaxies, where the achieved accuracies are sufficient compared to the statistical errors of SDSS volume. The validation and performance of the emulator are given by the comparison of the emulator predictions with the power spectra directly measured from the simulations for validation sets that are not used in the training. We demonstrate that the emulator outputs can be used to make model predictions for the redshift-space power spectrum of galaxies by employing user-fed models for the halo-galaxy connection, such as the halo occupation distribution. The emulator allows us to easily incorporate the Finger-of-God effect due to the virial motions of galaxies and the Alcock-Paczy\'{n}ski distortions. Our code can compute the redshift-space galaxy power spectrum in a CPU subseconds and is ready to perform the emulator-based cosmological analysis for the exiting and upcoming galaxy redshift surveys.

Targeted occupant surveys: A novel method to effectively relate occupant feedback with environmental conditions

Occupant satisfaction surveys are widely used in laboratory and field research studies of indoor environmental quality. Field studies pose several challenges because researchers usually have no control over the indoor environments experienced by building occupants, it is difficult to recruit and retain participants, and data collection methods can be cumbersome. With this in mind, we developed a survey platform that uses real-time feedback to send targeted occupant surveys (TOS) at specific indoor environmental conditions and stops sending survey requests when collected responses reach the maximum surveys required. We performed a pilot study of the TOS platform with occupants of a radiant heated and cooled building to target survey responses at 16 radiant slab surface (infrared) temperatures evenly distributed from 15 to 30 °C. We developed metrics and ideal datasets to compare the TOS platform against other occupant survey distribution methods. The results show that this novel method has a higher approximation to characteristics of an ideal dataset; 41% compared to 23%, 19%, and 12% of other datasets in previous field studies. Our TOS method minimizes the number of times occupants are surveyed and ensures a more complete and balanced dataset. This allows researchers to more efficiently and reliably collect subjective data for occupant satisfaction studies.

The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: GLAM-QPM mock galaxy catalogues for the emission line galaxy sample

ABSTRACT We present 2000 mock galaxy catalogues for the analysis of baryon acoustic oscillations (BAOs) in the Emission Line Galaxy (ELG) sample of the extended Baryon Oscillation Spectroscopic Survey Data Release 16 (eBOSS DR16). Each mock catalogue has a number density of $6.7 \times 10^{-4} h^3 \rm Mpc^{-3}$, covering a redshift range from 0.6 to 1.1. The mocks are calibrated to small-scale eBOSS ELG clustering measurements at scales of $\lesssim 30\, h^{-1}$Mpc. The mock catalogues are generated using a combination of GaLAxy Mocks (GLAM) simulations and the quick particle-mesh (QPM) method. GLAM simulations are used to generate the density field, which is then assigned dark matter haloes using the QPM method. Haloes are populated with galaxies using a halo occupation distribution. The resulting mocks match the survey geometry and selection function of the data, and have slightly higher number density that allows room for systematic analysis. The large-scale clustering of mocks at the BAO scale is consistent with data and we present the correlation matrix of the mocks.

Do model emission line galaxies live in filaments at z ∼ 1?

ABSTRACT Current and future cosmological surveys are targeting star-forming galaxies at z ∼ 1 with nebular emission lines. We use a state-of-the-art semi-analytical model of galaxy formation and evolution to explore the large-scale environment of star-forming emission line galaxies (ELGs). Model ELGs are selected such that they can be compared directly with the DEEP2, VVDS, eBOSS-SGC, and DESI surveys. The large-scale environment of the ELGs is classified using velocity–shear–tensor and tidal–tensor algorithms. Half of the model ELGs live in filaments and about a third in sheets. Model ELGs that reside in knots have the largest satellite fractions. We find that the shape of the mean halo occupation distribution of model ELGs varies widely for different large-scale environments. To interpret our results, we also study fixed number density samples of ELGs and galaxies selected using simpler criteria, with single cuts in stellar mass, star formation rate, and [O ii] luminosity. The fixed number density ELG selection produces samples that are close to L[O ii] and SFR-selected samples for densities above 10−4.2 h3 Mpc−3. ELGs with an extra cut in stellar mass applied to fix their number density, present differences in sheets and knots with respect to the other samples. ELGs, SFR, and L[O ii] selected samples with equal number density have similar large-scale bias but their clustering below separations of 1h−1 Mpc is different.

The completed SDSS-IV extended baryon oscillation spectroscopic survey: pairwise-inverse probability and angular correction for fibre collisions in clustering measurements

ABSTRACT The completed extended Baryon Oscillation Spectroscopic Survey (eBOSS) catalogues contain redshifts of 344 080 quasars at 0.8 &amp;lt; z &amp;lt; 2.2, 174 816 luminous red galaxies between 0.6 &amp;lt; z &amp;lt; 1.0, and 173 736 emission-line galaxies over 0.6 &amp;lt; z &amp;lt; 1.1 in order to constrain the expansion history of the Universe and the growth rate of structure through clustering measurements. Mechanical limitations of the fibre-fed spectrograph on the Sloan telescope prevent two fibres being placed closer than 62 arcsec in a single pass of the instrument. These ‘fibre collisions’ strongly correlate with the intrinsic clustering of targets and can bias measurements of the two-point correlation function resulting in a systematic error on the inferred values of the cosmological parameters. We combine the new techniques of pairwise-inverse probability and the angular upweighting (PIP+ANG) to correct the clustering measurements for the effect of fibre collisions. Using mock catalogues, we show that our corrections provide unbiased measurements, within data precision, of both the projected $\rm {\mathit{ w}_p}\left(\mathit{ r}_p\right)$ and the redshift-space multipole ξ(ℓ = 0, 2, 4)(s) correlation functions down to $0.1\, h^{-1}{\rm Mpc}$, regardless of the tracer type. We apply the corrections to the eBOSS DR16 catalogues. We find that, on scales $s\gtrsim 20\, h^{-1}{\rm Mpc}$ for ξℓ, as used to make baryon acoustic oscillation and large-scale redshift-space distortion measurements, approximate methods such as nearest-neighbour upweighting are sufficiently accurate given the statistical errors of the data. Using the PIP method, for the first time for a spectroscopic program of the Sloan Digital Sky Survey, we are able to successfully access the one-halo term in the clustering measurements down to $\sim 0.1\, h^{-1}{\rm Mpc}$ scales. Our results will therefore allow studies that use the small-scale clustering to strengthen the constraints on both cosmological parameters and the halo occupation distribution models.

Occupational structure of bearers of Jewish rabbinical, occupational and generic surnames

We study choice of profession in three groups of Russian-speaking Jewish families with different occupational distributions of the ancestors. This study continues exploration of the persistence of social status of families over centuries that was initiated in recent years. It was found previously that in some cases professions remain associated with the same surnames for many generations. Here the studied groups are defined by aclassof thesurname of individuals composing them. Theclassserves as a label that indicates a professional bias of the ancestors of the individual.One group are the bearers of the class of surnames which were used by rabbinical dynasties. The other group is constituted by occupational surnames, mostly connected to crafts. Finally, the last group are generic Jewish names defined as surnames belonging to neither of the above groups. We use the database that consists of 858 and 1057 of the first two groups, respectively, and 7471 generic Jewish surnames. The statistics of the database are those of individuals drawn at random from the considered groups. We determine shares of members of the groups working in a given type of occupations together with the confidence interval. The occupational type's definition agrees with International Standard Classification of Occupations. It is demonstrated that there is a statistically significant difference in the occupational structure of the three groups that holds beyond the uncertainty allowed by 95% confidence interval. We quantify the difference with a numerical measure of the overlap of professional preferences of different groups. We conclude that in our study the occupational bias of different population groups is preserved at least for two centuries that passed since the considered surnames appeared.

O ii] emitters in MultiDark-Galaxies and DEEP2

ABSTRACT We use three semi-analytical models (SAMs) of galaxy formation and evolution run on the same 1 h−1 Gpc MultiDark Planck2 cosmological simulation to investigate the properties of [O ii] emission line galaxies at redshift z ∼ 1. We compare model predictions with different observational data sets, including DEEP2–firefly galaxies with absolute magnitudes. We estimate the [O ii] luminosity ($L{\left[\rm{O\,{\small II}}\right]}$) of our model galaxies using the public code get_ emlines , which ideally assumes as input the instantaneous star formation rates (SFRs). This property is only available in one of the SAMs under consideration, while the others provide average SFRs, as most models do. We study the feasibility of inferring galaxies’ $L{\left[\rm{O\,{\small II}}\right]}$ from average SFRs in post-processing. We find that the result is accurate for model galaxies with dust attenuated $L{\left[\rm{O\,{\small II}}\right]}$ ≲ 1042.2 erg s−1 ($\lt 5{{\ \rm per\ cent}}$ discrepancy). The galaxy properties that correlate the most with the model $L{\left[\rm{O\,{\small II}}\right]}$ are the SFR and the observed-frame u and g broad-band magnitudes. Such correlations have r-values above 0.64 and a dispersion that varies with $L{\left[\rm{O\,{\small II}}\right]}$ . We fit these correlations with simple linear relations and use them as proxies for $L{\left[\rm{O\,{\small II}}\right]}$ , together with an observational conversion that depends on SFR and metallicity. These proxies result in [O ii] luminosity functions and halo occupation distributions with shapes that vary depending on both the model and the method used to derive $L{\left[\rm{O\,{\small II}}\right]}$ . The amplitude of the clustering of model galaxies with $L{\left[\rm{O\,{\small II}}\right]}$ &amp;gt;1040.4 erg s−1 remains overall unchanged on scales above 1 $\, h^{-1}$ Mpc, independently of the $L{\left[\rm{O\,{\small II}}\right]}$ computation.

Analysis of activity, space and user relations in urban squares

With the increasing density of built spaces in urban areas, the need for open spaces increases every day. Squares are one of the most important of these open spaces. Urban squares allow various activities and exhibit functional differences based on location and culture. The diversity of activities conducted in squares is extremely important for the quality and viability of liveable urban spaces. Urban residents prefer spaces that are suitable for individual requirements and desires and allow for a variety of activities. These spaces also contribute to social life. This article aimed to determine the user profile, occupancy, facilities and activity diversity at the Atatürk Plaza (Trabzon urban square) in Trabzon, the capital city of Trabzon Province, Turkey. The occupants of the square and their numbers were analysed via the behaviour observation method. As a result of the observations conducted in the square over one year, 17 activities were identified. The majority of these activities were necessary activities and that the most common activity was walking. The occupancy density and distribution in the square were analysed using the Geographical Information System (GIS). These research findings and analyses could serve as a guide for future urban square and urban open space designs.

"Automation, gigs, and other labor market tales: the Philippines in the Fourth Industrial Revolution"

The paper discusses two topics that frequently surface in conversations about the Fourth Industrial Revolution ( 4IR ): the threat of labor displacement due to automation and the growth of alternative employment arrangements. Using the “task approach” to review recent research on the “future of work” in the Philippines, the paper argues that predictions not informed by the task intensity of jobs are less compelling. The “job polarization” thesis is also examined and the observation made that changes in the occupational distribution of employment seem to be more closely associated with a structural transformation explanation. In the second part, the “gig economy” is discussed in the broader context of work arrangements that have emerged and disrupted the standard employment relationship. The limitations of household-based labor force surveys as a source of data on gig activity are noted. The paper concludes with a brief discussion of 4IR challenges in terms of human resource development, unemployment protection, and the reform of labor laws.

The impact of chronic pain on patients and spouses: Consequences on occupational status, distribution of household chores and care-giving burden.

Informal care-giving by spouses has become frequent in chronic pain settings. However, the impact of pain on occupational, functional and health outcomes in spouses has not been systematically investigated. The goal of the present study was to examine the impact of pain on both patient and spousal outcomes. In the present study, the impact of chronic pain on 114 heterosexual dyads was explored (patients: 59% females, average age=57.81years, SD=11.85; spouses: 41% females, average age=57.32years, SD=12.15). Overall, both patients and spouses reported important consequences of pain on outcomes, including occupational status distribution of household chores and marital satisfaction). Almost 52% of spouses indicated a high-to-severe burden. A multivariate model with spouse and patient factors accounted for 37.8% of the variance of this burden. In the model, patient disability (β=0.36, p=.002), spouses' change in occupational status (β=0.26, p=.002) and spousal perception of marital adjustment (β=-0.36, p<.001) were uniquely associated with burden. The results indicate that the impact of chronic pain should be evaluated both for patients and spouses and point to patient and spouse factors that might contribute to spousal burden, which might help guide family interventions in a more effective manner. Research has shown that chronic pain poses a significant burden on individuals, which increases their reliance on others for assistance. However, the burden of informal care-giving assumed by spouses of patients with chronic pain has not been systematically investigated. This study offers new insights into the impact of chronic pain on patients and their spouses, which might provide empirical foundation for the development of new avenues for intervention aimed at promoting adjustment in patients with chronic pain and spouses who act as informal caregivers.
