description: Based on a detailed theoretical examination of the lattice distortion in high-index epilayers in terms of continuum mechanics, expressions are deduced that allow the calculation and experimental determination of the strain tensor for (hhl)-oriented (Ga,Mn)As layers. Analytical expressions are derived for the strain-dependent free-energy density and for the resistivity tensor for monoclinic and orthorhombic crystal symmetry, phenomenologically describing the magnetic anisotropy (MA) and anisotropic magnetoresistance (AMR) by appropriate anisotropy and resistivity parameters, respectively. Applying the results to (113)A orientation with monoclinic crystal symmetry, the expressions are used to determine the strain tensor and the shear angle of a series of (113)A-oriented (Ga,Mn)As layers by high-resolution x-ray diffraction and to probe the MA and AMR at 4.2 K by means of angle-dependent magnetotransport. Whereas the transverse resistivity parameters are nearly unaffected by the magnetic field, the parameters describing the longitudinal resistivity are strongly field dependent.

Engaging Indigenous Leaders in Tanah Papua's HIV Responses
Creators: name: Munro, Jenny
Publisher: name: Canberra, ACT : Coral Bell School of Asia Pacific Affairs, College of Asia and the Pacific, The Australian National University
Year: 2015

description: HIV in Tanah Papua primarily affects indigenous Papuans (as opposed to the non-indigenous Indonesian population), and is not limited to particular groups typically regarded as ‘high risk’ for HIV, such as sex workers, intravenous drug users, or men who have sex with men (Munro 2015b). HIV is also most prevalent in youth aged 15–24. This In Brief elaborates on one of the key recommendations of the workshop, ‘Developing an HIV Prevention and Control Strategy for Papuans in Tanah Papua’, held in Manokwari in November 2014: the need to better engage indigenous Papuan leaders and communities.

Seeding the formation of cold gaseous clouds in Milky Way size halos

description: We use one of the highest resolution cosmological SPH simulations to date to demonstrate that cold gaseous clouds form around Milky Way size galaxies. We further explore mechanisms responsible for their formation and show that a large fraction of clouds originate as a consequence of late-time filamentary "cold mode" accretion. Here, filaments that are still colder and denser than the surrounding halo gas, are not able to connect directly to galaxies, as they do at high redshift, but are instead susceptible to the combined action of cooling and Rayleigh-Taylor instabilities at intermediate radii within the halo leading to the production of cold, dense pressure-confined clouds, without an associated dark matter component. This process is aided through the compression of the incoming filaments by the hot halo gas and expanding shocks during the halo buildup. Our mechanism directly seeds clouds from gas with substantial local overdensity, unlike in previous models, and provides a channel for the origin of cloud complexes. These clouds can later "rain" onto galaxies, delivering fuel for star formation. Owing to the relatively large cross section of filaments and the net angular momentum carried by the gas, the clouds will be distributed in a modestly flattened region around a galaxy.

title: Patterns of Response and Nonresponse from Teachers to Traditional and Web Surveys
Creators: name: Mertler, Craig A.
Publisher: name: University of Massachusetts Amherst
Year: 2002

description: This paper discusses the results of a study comparing the psychometric qualities of two forms of an identical survey: one administered in paper-and-pencil format and the other administered in Web format. Two groups of teachers were surveyed. One group received a paper-and-pencil version of the survey; the other group was directed to a Web-based version of the survey. While the rates of response were quite discrepant, the respective measures of reliability were extremely similar for the two versions of the survey. Similarly, there were no significant differences between the two groups on any of the seven subscales, nor on the total score. A follow-up survey was conducted with the nonrespondents in the Web group in order to investigate reasons behind their decision not to complete the survey. Several methodological issues are raised as a result of the follow-up. Accessed 33,904 times on https://pareonline.net from October 07, 2003 to December 31, 2019.

description: This article concentrates on one of the newer techniques, namely, resampling, and attempts to address the above issues. First, concepts of different types of resampling will be introduced with simple examples. Next, software applications for resampling are illustrated. Contrary to popular beliefs, many resampling tools are available in standard statistical applications such as SAS and SyStat. Resampling can also be performed in spreadsheet programs such as Excel. Last but not least, arguments for and against resampling are discussed. I propose that there should be more than one way to construe probabilistic inferences and that counterfactual reasoning is a viable means to justify use of resampling as an inferential tool.

description: Chern-Simons models for gravity are interesting because they provide with a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largely been the perceived remoteness from standard General Relativity, based on the presence of higher powers of the curvature in the Lagrangian (except, remarkably, for three-dimensional spacetime). Here we report on a simple model that suggests a mechanism by which standard General Relativity in five-dimensional spacetime may indeed emerge at a special critical point in the space of couplings, where additional degrees of freedom and corresponding "anomalous" Gauss-Bonnet constraints drop out from the Chern-Simons action. To achieve this result, both the Lie algebra g and the symmetric g-invariant tensor that define the Chern-Simons Lagrangian are constructed by means of the Lie algebra S-expansion method with a suitable finite abelian semigroup S. The results are generalized to arbitrary odd dimensions, and the possible extension to the case of eleven-dimensional supergravity is briefly discussed.

While several lines of inquiry have now converged on the conclusion that these factors play a key role in student learning, findings vary considerably due to differences in definitions and approaches to assessing student engagement levels. The purposes of this overview are to (i) outline some key dimensions of student engagement based on an integrated review of relevant literature, and (ii) describe the various methods that have been used to assess engagement levels in empirical research studies. Specifically, the primary goal was to review approaches to assessing student engagement levels on a classwide basis, and to provide educators with a range of options for developing relevant assessment protocols within their own contexts.

Half-metallic ferrimagnet formed by substituting Fe for Mn in semiconductor MnTe

description: A ternary ferrimagnetic half-metal, constructed through substituting 25% Fe for Mn in zincblende semiconductor MnTe, is predicted in terms of accurate first-principles calculations. It has a large half-metallic (HM) gap of 0.54eV and its ferrimagnetic order is very stable against other magnetic fluctuations. The HM ferrimagnetism is formed because the complete moment compensation in the antiferromagnetic MnTe is replaced by an uncomplete one in the Fe-substituted MnTe. This should make a novel approach to new HM materials. The half-metal could be fabricated because Fe has good affinity with Mn, and useful for spintronics.

description: We present new mid-infrared and submillimetre observations for a sample of eight high redshift type-2 QSOs located in the Chandra Deep Field South. The sources are X-ray absorbed with luminosities in excess of 10^44 erg/s. Two of the targets have robust detections, S/N > 4, while a further three targets are marginally detected with S/N > =2.5. All sources are detected in multiple mid-infrared bands with the Spitzer Space Telescope. The multiwavelength spectral energy distributions (SEDs) of the type-2 QSOs are compared to those of two local ultraluminous galaxies (Arp220 and IR22491) in order to assess contributions from a star-forming component in various parts of the SED. We suggest that their submillimetre emission is possibly due to a starburst while a large fraction of the mid-infrared energy is likely to originate in the obscured central quasar. Using the mid-infrared and submm observations we derive infrared luminosities which are found to be in excess of L>10^12Lsun. The submillimetre (850micron) to X-ray (2 keV) spectral indices (alpha_SX) span a wide range. About half of the type-2 QSOs have values typical for a Compton-thick AGN with only 1 per cent of the nuclear emission seen through scattering and, the remaining with values typical of submm-bright galaxies. Combining the available observational evidence we outline a possible scenario for the early stages of evolution of these sources.

description: Surveys allow information to be collected from a sample group and generalized to the population at large. Because they are low cost and easy to implement, mail surveys are used more frequently for social research than either telephone or face-to-face interviews. Those conducting surveys should recognize four potential sources of error -- sampling error, noncoverage error, non-response error, and measurement error -- and take steps to minimize their impact. Any one of these sources of error may make the survey results unacceptable (Groves, 1989; Salant and Dillman, 1994; Dillman, 1991, 1999).

description: Collimated ejections of plasma called "coronal hole jets" are commonly observed in polar coronal holes. However, such coronal jets are not only a specific features of polar coronal holes but they can also be found in coronal holes appearing at lower heliographic latitudes. In this paper we present some observations of "equatorial coronal hole jets" made up with data provided by the STEREO/SECCHI instruments during a period comprising March 2007 and December 2007. The jet events are selected by requiring at least some visibility in both COR1 and EUVI instruments. We report 15 jet events, and we discuss their main features. For one event, the uplift velocity has been determined as about 200 km/s, while the deceleration rate appears to be about 0.11 km/s2, less than solar gravity. The average jet visibility time is about 30 minutes, consistent with jet observed in polar regions. On the basis of the present dataset, we provisionally conclude that there are not substantial physical differences between polar and equatorial coronal hole jets.

description: An high peak current (up to 100 A) and a very short pulse (1 ms) generator was used to perform electrolysis in D_20-LiOD solution using a Pd sheet as a cathode and a Pt net as an anode. This high power pulse (up to 50 KW) can be rated up to 20 KHz. Very high D/Pd values (up to about 1:1) has been reached with any cold-worked Pd sheets used. A very hard sheet (about 300 Hv) has generated an excess heat of the order of 15% for a long time (some weeks). Some considerations about the metallurgy of electrodes are performed and an effort is made to correlate the excess heat with metallurgical parameters, over-voltage and surface resistance.

description: One of the major discoveries of the Extreme ultraviolet Imaging Telescope (EIT) on SOHO were intensity enhancements propagating over a large fraction of the solar surface. The physical origin(s) of the so-called `EIT' waves is still strongly debated. They are considered to be either wave (primarily fast-mode MHD waves) or non-wave (pseudo-wave) interpretations. The difficulty in understanding the nature of EUV waves lies with the limitations of the EIT observations which have been used almost exclusively for their study. Their limitations are largely overcome by the SECCHI/EUVI observations on-board the STEREO mission. The EUVI telescopes provide high cadence, simultaneous multi-temperature coverage, and two well-separated viewpoints. We present here the first detailed analysis of an EUV wave observed by the EUVI disk imagers on December 07, 2007 when the STEREO spacecraft separation was $\approx 45^\circ$. Both a small flare and a CME were associated with the wave cadence, and single temperature and viewpoint coverage. These limitations are largely overcome by the SECCHI/EUVI observations on-board the STEREO mission. The EUVI telescopes provide high cadence, simultaneous multi-temperature coverage, and two well-separated viewpoints. Our findings give significant support for a fast-mode interpretation of EUV waves and indicate that they are probably triggered by the rapid expansion of the loops associated with the CME.

description: The Rossi X-ray Timing Explorer has observed five outbursts from the transient 2.5 ms accretion-powered pulsar SAX J1808.4-3658 during 1998-2008. We present a pulse timing study of the most recent outburst and compare it with the previous timing solutions. The spin frequency of the source continues to decrease at a rate of (-5.5+/-1.2)x10^-18 Hz/s, which is consistent with the previously determined spin derivative. The spin-down occurs mostly during quiescence, and it is most likely due to the magnetic dipole torque from a B = 1.5x10^8 G dipolar field at the neutron star surface. We also find that the 2 hr binary orbital period is increasing at a rate of (3.80+/-0.06)x10^-12 s/s, also consistent with previous measurements. It remains uncertain whether this orbital change reflects secular evolution or short-term variability.

description: We derive certain constraints on the reflection matrix for reflection from a plane, nonmagnetic, optically anisotropic surface using a reciprocity theorem stated long ago by van de Hulst in the context of scattering of polarized light. The constraints are valid for absorbing and chiral media and can be used as tools to check the consistency of derived expressions for such matrices in terms of the intrinsic parameters of the reflecting medium as illustrated by several examples.

Bayesian Approach to Find a Long-Term Trend in Erratic Polarization Variations Observed in Blazars

description: We developed a method to separate a long-term trend from observed temporal variations of polarization in blazars using a Bayesian approach. The temporal variation of the polarization vector is apparently erratic in most blazars, while several objects occasionally exhibited systematic variations, for example, an increase of the polarization degree associated with a flare of the total flux. We assume that the observed polarization vector is a superposition of distinct two components, a long-term trend and a short-term variation component responsible for short flares. Our Bayesian model estimates the long-term trend which satisfies the condition that the total flux correlates with the polarized flux of the short-term component. We demonstrate that assumed long-term polarization components are successfully separated by the Bayesian model for artificial data. We applied this method to photopolarimetric data of OJ 287, S5 0716+714, and S2 0109+224. Simple and systematic long-term trends were obtained in OJ 287 and S2 0109+224, while no such a trend was identified in S5 0716+714. We propose that the apparently erratic variations of polarization in OJ 287 and S2 0109+224 are due to the presence of the long-term polarization component. The behavior of polarization in S5 0716+714 during our observation period implies the presence of a number of polarization components having a quite short time-scale of variations.

title: Matrix Sampling of Items in Large-Scale Assessments

Publisher: name: University of Massachusetts Amherst
Year: 2002

description: Matrix sampling of items – that is, division of a set of items into different versions of a test form – is used by several large-scale testing programs. Like other test designs, matrixed designs have both advantages and disadvantages. For example, testing time per student is less than if each student received all the items, but the comparability of student scores may decrease. Also, curriculum coverage is maintained, but reporting of scores becomes more complex. In this paper, matrixed designs are compared with more traditional designs in nine categories of costs: development costs, materials costs, administration costs, educational costs, scoring costs, reliability costs, comparability costs, validity costs, and reporting costs. In choosing among test designs, a testing program should examine the costs in light of its mandate(s), the content of the tests, and the financial resources available, among other considerations.

Year: 1997

description: A new analysis of he long-distance two-photon dispersive amplitude of K_L->μ^+ μ^- is presented. We introduce a phenomenological parametrization of the K->γ^*γ^* form factor, constrained at low energies by KL->γl+l- (l=e,μ) data and high energies by perturbative QCD. Using this form factor provide a reliable estimate of magnitude and relative uncertainty of the two-photon dispersive contribution in K_L->μ^+ μ^-. We finally discuss the implications of this analysis for the extraction of short-distance information from BB(K_L->μ^+ μ^-).
Social Connections and the Spillover of Sanctions: Evidence from Hollywood

Subjects: subject: social connections

subject: actors and filmography
subject: #MeToo movement
subject: Harvey Weinstein

description: How does the impact of social sanctions transmit through social connections? In this paper, I study this question by drawing from the accusation of Harvey Weinstein during the #MeToo movement in Hollywood. Using a newly assembled dataset on actor and film information, I find that actors who had collaborated with Weinstein suffered from a sharp and persistent decrease in film output following his accusation in 2017, while they also tend to participate in more female-directed films. In particular, the drop in film quantity can be attributed to both genders, while the increase in collaborations with female directors is almost entirely driven by female actors.Further evidence shed light on two potential channels at play: the reduction of film output is likely the “mechanical” consequence of losing connections and thus access to resources, while heterogeneous participation in female-directed films is likely to imply actors’ urge to signal their morality as well as the difficulty in doing so due to their damaged reputation.

description: There is something incalculable about teacher expertise and whether it can be observed, detected, quantified, and as per current educational policies, used as an accountability tool to hold Americaâ€™s public school teachers accountable for that which they do (or do not do well). In this commentary, authors (all of whom are former public school teachers) argue that rubric-based teacher observational systems, developed to assess the extent to which teachers adapt and follow sets of rubric-based rules, might actually constrain teacher expertise. Moreover, authors frame their comments using the Dreyfus Model (1980, 1986) to illustrate how observational systems and the rational conceptions on which they are based might be stifling educational progress and reform.
