description: We consider constraints on a phenomenological dark-matter model consisting of two nearly degenerate particle species using observed properties of the Milky Way satellite galaxy population. The two parameters of this model, assuming the particle masses are >~ GeV, are v_k, the recoil speed of the daughter particle, and tau, the lifetime of the parent particle. The satellite constraint that spans the widest range of v_k is the number of satellites that have a mass within 300 pc M300 > 5 x 10^6 solar masses, although constraints based on M300 in the classical dwarfs and the overall velocity function are competitive for v_k >~ 50 km/s. In general, we find that tau

Equality, freedom, and the security of a free state were key formative tenets that the founders of our nation sought to enshrine in its founding documents. Now it is once again time to act in the pursuit of these goals to address the profound impact of firearms. More than ever, we need open lines of discussion and communication that draw people together and help us find collective solutions that build on the ideals on which America was founded. The articles in this edition of the NCMJ demonstrate the breadth and depth of approaches to addressing the firearm injury and death crisis we all face.

description: The KATRIN neutrino experiment is a next-generation tritium beta decay experiment aimed at measuring the mass of the electron neutrino to better than 200 meV at 90% C.L. Due to its intense tritium source, KATRIN can also serve as a possible target for the process of neutrino capture, νe +3H \to 3He+ + e-. The latter process, possessing no energy threshold, is sensitive to the Cosmic Neutrino Background (CνB). In this paper, we explore the potential sensitivity of the KATRIN experiment to the relic neutrino density. The KATRIN experiment is sensitive to a CνB over-density ratio of 2.0x 10^9 over standard concordance model predictions (at 90% C.L.), addressing the validity of certain speculative cosmological models.

A role clarity framework for gathering business activities
Creators: name: Taghavi, Atefeh
Publisher: name: University of British Columbia
Year: 2015

description: To date, requirement engineering (RE) studies have proposed several methods for efficiently gathering correct and complete requirements for developing information systems. As one of the most widely-used RE approaches, goal-oriented requirement engineering (GORE) determines requirements based on an organization's goals for its information system. GORE methods vary, but most do not clarify how they obtain the primary goals. To address this uncertainty, a few studies have introduced some guidelines. This researcher believes however that further investigation is required to improve organizational analysis, and thereby attain more accurate definition of goals for the information system. The first step in organizational analysis should be defining business activities of users. To achieve such understanding, this thesis develops a role clarity framework, that operationalizes the concept of role ambiguity drawn from two organizational theories: role dynamics (Kahn, Wolfe, Quinn, Snoek, & Rosenthal, 1964) and goal setting and task performance (Locke & Latham, 1990). According to the proposed framework, a role’s expectations, activities, and consequences are essential for describing a role’s business activities. Findings reveal that a role’s activities express the core of a role’s business activities. In addition, a role’s expectations and consequences contain contextual information supporting analysts in collecting and evaluating a role’s business activities. More specifically, expectations clarify the origin of business activities, and consequences enable analysts to verify current business activities and anticipate potential ones.

description: Aims. We report the first detailed X-ray study of the supernova remnant (SNR) G304.6+0.1, achieved with the XMM-Newton mission. Methods. The powerful imaging capability of XMM-Newton was used to study the X-ray characteristics of the remnant at different energy ranges. The X-ray morphology and spectral properties were analyzed. In addittion, radio and mid-infrared data obtained with the Molonglo Observatory Synthesis Telescope and the Spitzer Space Telescope were used to study the association with the detected X-ray emission and to understand the structure of the SNR at differents wavelengths. Results. The SNR shows an extended and arc-like internal structure in the X-ray band with out a compact point-like source inside the remnant. We find a high column density of NH in the range 2.5-3.5x1022 cm-2, which supports a relatively distant location (d $\geq$ 9.7 kpc). The X-ray spectrum exhibits at least three emission lines, indicating that the X-ray emission has a thin thermal plasma origin, although a non-thermal contribution cannot be discarded. The spectra of three different regions (north, center and south) are well represented by a combination of a non-equilibrium ionization (PSHOCK) and a power-law (PL) model. The mid-infrared observations show a bright filamentary structure along the north-south direction coincident with the NW radio shell. This suggests that Kes 17 is propagating in a non-uniform environment with high density and that the shock front is interacting with several adjacent massive molecular clouds. The good correspondence of radio and mid-infrared emissions suggests that the filamentary features are caused by shock compression. The X-ray characteristics and well-known radio parameters indicate that G304.6+0.1 is a middle-aged SNR (2.8-6.4)x104 yr old and a new member of the recently proposed group of mixed-morphology SNRs.

description: Papillary thyroid carcinoma (PTC) is a differentiated type of thyroid malignancy with a high incidence. Long non-coding RNA (lncRNA) DUXAP8 has been reported to participate in the proliferation, migration, and invasion of several cancer types. However, its association with PTC has not yet been reported. The current study aimed to investigate the role of DUXAP8 in PTC and revealed the underlying mechanisms. The expression of DUXAP8 was knocked down in two PTC cell lines and the effects of DUXAP8 on the PTC biological behavior were examined by cell counting kit-8 (CCK-8), wound healing, and transwell invasion assays. Luciferase reporter assay was used to detect the binding activity between miR-223-3p and DUXAP8. We found that knockdown of DUXAP8 inhibited the proliferation, migration, and invasion of PTC cells. DUXAP8 could sponge miR-223-3p through the specific binding site. CXCR4 was a target of miR-223-3p. The malignant phenotypes of the PTC cells were suppressed by the over-expression of miR-223-3p. Moreover, miR-223-3p inhibition or CXCR4 over-expression partly restored the proliferation, migration, and invasion activities of DUXAP8-downregulated PTC cells. The results evidenced that DUXAP8 acted as an oncogene in PTC, these effects seemed to partly dependent on the miR-223-3p/CXCR4 axis.

description: Let R be a polynomial ring and M a finitely generated graded R-module of maximal grade (which means that the ideal I_t(\cA) generated by the maximal minors of a homogeneous presentation matrix, \cA, of M has maximal codimension in R). Suppose X:=Proj(R/I_t(\cA)) is smooth in a sufficiently large open subset and dim X > 0. Then we prove that the local graded deformation functor of M is isomorphic to the local Hilbert (scheme) functor at X \subset Proj(R) under a week assumption which holds if dim X > 1. Under this assumptions we get that the Hilbert scheme is smooth at (X), and we give an explicit formula for the dimension of its local ring. As a corollary we prove a conjecture of R. M. Miró-Roig and the author that the closure of the locus of standard determinantal schemes with fixed degrees of the entries in a presentation matrix is a generically smooth component V of the Hilbert scheme. Also their conjecture on the dimension of V is proved for dim X > 0. The cohomology H^i_{*}({\cN}_X) of the normal sheaf of X in Proj(R) is shown to vanish for 0 < i < dim X-1. Finally the mentioned results, slightly adapted, remain true replacing R by any Cohen-Macaulay quotient of a polynomial ring.

Teacher turf wars : a case study of the impacts of intra-school competition on elective teachers in British Columbia’s public schools
Creators: name: Pirbhai, Mariam
Publisher: name: University of British Columbia
Year: 2015

description: This qualitative study explored the impacts of heightened intra-school competition between elective teachers in three public secondary schools in British Columbia (BC). This study used semi-structured interview data from seven secondary school elective teachers from three secondary schools within one BC school district to explore how teachers perceive and respond to intra-school competition. The BC Liberal government introduced neoliberal policies in 2002 in the BC public school system through the School Amendment Act of 2002 (Bill 34) legislation. Changes included giving parents and students the right to choose to attend any school or program beyond their neighborhood catchment area, provided that there is availability, providing public accountability, establishing greater school board autonomy, and allowing for the creation of for-profit school board companies. The findings show that all of the teachers interviewed felt that they were in competition with their colleagues for student enrolment, regardless of whether or not they chose to actively engage in competitive practices. The majority of the teachers interviewed chose to market their programs to their students. The teachers interviewed did not feel that competition impacted their teaching practices, as they believed that they strived to engage their students due to their own personal motivations rather than through competition. Teachers were keen to protect their specialty area and skeptically viewed new course offerings that may infringe on their area of teaching. Despite the competitive environment, overall teachers did not find that competition for student enrolment impacted their relationships with their colleagues. This study sheds light on how teachers compete and market their courses to drive their course enrolment in the competitive environment that they experience in their schools. This study also illustrates how teachers may act out of self-interest to protect their teaching interests, so that they can continue to teach the courses that they believe are of value to their students and society.

PURPOSE: Investigate residential segregation and prenatal depression in a non-Hispanic (NH) Black and Hispanic North Carolina pregnancy cohort. METHODS: Demographics, prenatal depression (Center for Epidemiological Studies Depression scale ≥16), and residence from the 2006-2009 Newborn Epigenetic Survey were linked to Census-tract levels of racial and economic segregation (Index of Concentration at the Extremes) from the American Community Survey 2005-2009 5-year estimates. Adjusted prevalence ratios (aPR) for prenatal depression compared living in Index of Concentration at the Extremes tertiles 1 and 2 (higher proportion NH Black or Hispanic and/or low income) to 3 (higher proportion NH white and/or high-income), accounting for neighborhood clustering, age, education, employment, parity, and marital status. RESULTS: Among the 773 survey participants (482 NH Black and 291 Hispanic), 35.7% and 27.2% of NH Black and Hispanic participants had prenatal depression, respectively. For NH Black participants, depression prevalence was 17% lower for tertile 1 versus 3 for the NH Black/white (aPR=0.83; 95% CI=0.62-1.10), low/high income (aPR=0.83; 95% CI=0.62-1.11), and low-income NH Black/high-income NH white (aPR=0.82; 95% CI=0.61-1.09) measures. For Hispanic participants, estimates were weaker in the opposite direction for the Hispanic/NH white (aPR=1.02; 95% CI=0.71-1.47), low/high income (aPr=1.14; (95% CI=0.76-1.69), and low-income Hispanic/high-income NH white (aPR=1.12; 95% CI=0.78-1.60) measures. CONCLUSIONS: Residential segregation's impact on prenatal depression may differ by race/ethnicity and level of segregation, but findings are imprecise due to small sample sizes. Longitudinal research spanning greater geographic areas is needed.

description: The effects induced by long temporal correlations of the velocity gradients on the dynamics of a flexible polymer are investigated by means of theoretical and numerical analysis of the Hookean and FENE dumbbell models in a random renewing flow. For Hookean dumbbells, we show that long temporal correlations strongly suppress the Weissenberg-number dependence of the power-law tail characterising the probability density function (PDF) of the elongation. For the FENE model, the PDF becomes bimodal, and the coil-stretch transition occurs through the simultaneous drop and rise of the two peaks associated with the coiled and stretched configurations, respectively.

description:
For ethnoracially minoritized and immigrant youth, identity formation involves efforts to integrate social identities that are derived from their ethnic-racial group memberships (i.e., ethnic-racial identity) and their connection to the country in which they reside (i.e., national identity). This study investigated the extent to which these two social identities were simultaneously associated with adolescents’ psychosocial adjustment via their associations with the integration of these identities (i.e., bicultural identity integration) and across adolescents’ identity domains (i.e., global identity coherence). This cross-sectional study (January 2020) included a US ethnoracially diverse sample of 355 adolescents ( M age = 15.95 years; SD = 0.79; 50.4% female; 40.6% Latino/a/x, 29.0% White, 13.2% Black, 8.2% Asian, 7.0% other; 76.1% US-born; 76.9% had at least one foreign-born parent) who completed online surveys in class. Structural equation path analyses with bias-corrected bootstrapping were conducted to test a theoretical sequential mediation model of identity and adjustment. Findings indicated that national American identity explained significant variance in adolescent psychosocial adjustment (i.e., higher academic engagement and self-esteem) via its unique associations with bicultural identity integration and global identity coherence. Furthermore, sensitivity analyses revealed some support for alternate models suggesting that the examined identity constructs may work in tandem with one another to inform adolescent psychosocial adjustment. This study highlights the multifaceted nature of social identity development and provides preliminary evidence regarding how the simultaneous development of adolescents’ ethnic-racial and national identities informs their psychosocial adjustment.

description: Scientific data is expensive and time consuming to generate. The gathered data

is refined and the results published, but until recent years the raw data has

been hidden away from outsiders. The same researchers and their peers in the

same institutions have had an upper hand, as they had a lot of raw data to test

their hypotheses on before starting a new study. The goal of open access data

repositories is that scientists not only publish the results, but also publish the

data behind it for others to study and to generate more results. This opens up

the scientific research capabilities to everyone everywhere, if someone has

already gathered the data needed.

Open access repositories are platforms to store the data. They are free and

normally specialized in one field of study. There’s a plethora of public open

access repositories and it’s impossible to single out any recommended ones.

Most scientific journals have their recommended repositories. Repositories are

normally used through a software that generates the metadata at the same

time, but there are sites that take metadata filled by hand. Repositories provide

an API (application programming interface) and anyone can make a program to

use the repository through the API.

description: We examine the zero-range limit of the finite square well in arbitrary dimensions through a systematic analysis of the reduced, s-wave two-body time-independent Schrödinger equation. A natural consequence of our investigation is the requirement of a delta-function multiplied by a regularization operator to model the zero-range limit of the finite-square well when the dimensionality is greater than one. The case of two dimensions turns out to be surprisingly subtle, and needs to be treated separately from all other dimensions.

We provide a necessary and sufficient condition for successful decoding of zigzag cycle codes over the MBIOS channel by the belief propagation decoder. We consider an expurgated ensemble of non-binary LDPC codes by using the above necessary and sufficient condition, and hence exhibit lower error floors. Finally, we show lower bounds of the error floors for the expurgated LDPC code ensembles over the MBIOS channel.

Three essays in operations management
Creators: name: Geng, Xin
Publisher: name: University of British Columbia
Year: 2015

description: There are three topics in operations management presented in this dissertation. Each topic deals with a specific issue encountered by managers from various organizations. In the context of non-profit operations, we study a two-customer sequential resource allocation problem whose objective function has a max-min form. For finite discrete demand distribution, we give a sufficient and necessary condition under which the optimal solution has monotonicity property. However, this property never holds with unbounded discrete distributions. Then, we look at a service system with two servers serving arriving single class jobs. Servers care about fairness, and they can endogenously choose capacities in response to the routing policy. We focus on four commonly seen policies and examine the two-server game where the servers' objective functions have a term that reflects fairness. Theoretical results concerning the existence and uniqueness of the Nash equilibrium are proved for some policies. Numerical studies also provide insights on servers' off-equilibrium behaviours and the system efficiency under different policies. Finally, suppose that a firm has heterogeneous servers who provide service with different quality levels, and that there exists a learning curve of the servers so that the quality can be improved by accumulating experience in serving customers. As customers decide their service procurement based on the quality and system congestion, what pricing scheme should the firm adopt to achieve optimal revenue in the long run? We compare a traditional pricing scheme with a proposed one, and theoretically establish the superiority of the proposed pricing scheme. Based on both theoretical and numerical evidence, we characterize the sensitivity of some parameters with respect to the comparison.

description: Bankruptcy prediction is very important for all the organization since it affects the economy and rise many social problems with high costs. There are large number of techniques have been developed to predict the bankruptcy, which helps the decision makers such as investors and financial analysts. One of the bankruptcy prediction models is the hybrid model using Fuzzy C-means clustering and MARS, which uses static ratios taken from the bank financial statements for prediction, which has its own theoretical advantages. The performance of existing bankruptcy model can be improved by selecting the best features dynamically depend on the nature of the firm. This dynamic selection can be accomplished by Genetic Algorithm and it improves the performance of prediction model.

Data were from Centers for AIDS Research Network of Integrated Clinical Systems (CNICS), 2005–2022. TW were identified using clinical data/identity measures. PWH (n = 1285) were included in analyses (275 TW, 547 CM, 463 CW). Cross-sectional multivariable analyses compared HIV outcomes/co-morbidities between TW/CM and TW/CW, and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) were estimated. TW had poorer adherence (> 90% adherent; aOR 0.57; 95%CI 0.38, 0.87) and were more likely to miss ≥ 3 visits in the past year than CM (aOR 1.50, 95%CI 1.06, 2.10); indicated more anxiety compared to both CM and CW (p ≤ 0.001, p = 0.02); hepatitis C infection (p = 0.03) and past-year/lifetime substance treatment (p = 0.004/p = 0.001) compared to CM; and substance use relative to CW. TW with HIV differed in HIV clinical outcomes and co-morbidities from CM and CW.

description: La PC est la cause la plus fréquente de handicap physique chez l'enfant [1]. Elle est associée à de multiples comorbidités et il a été démontré qu'elle a un effet significatif sur la qualité de vie des individus, quel que soit le degré de gravité de la maladie. La prévalence de la PC est d'environ 2-2,2/1000 naissances vivantes dans les pays disposant de ressources suffisantes. Les données disponibles pour les pays en développement sont limitées, mais la prévalence de la PC a été estimée à 10/1000 en Afrique. Mais attention les enfants présentant des troubles du mouvement dès leur plus jeune âge sont le plus souvent diagnostiqués comme ayant une PC. Cependant, il existe un large éventail de troubles qui peuvent imiter la PC. Ces troubles peuvent avoir des pronostics différents et peuvent nécessiter une évaluation et un traitement spécifique à la maladie, ce qui pourrait changer les résultats, et un conseil approprié à la famille concernant la génétique et les risques de récurrence sera nécessaire.

description: SuWt2 is a planetary nebula (PN) consisting of a bright ionized thin ring seen nearly edge-on. It has a bright (V=12) central star, too cool to ionize the PN, which we discovered to be an eclipsing binary. A spectrum from IUE did not reveal a UV source. We present extensive ground-based photometry and spectroscopy of the central binary collected over the ensuing two decades, resulting in the determination that the orbital period of the eclipsing pair is 4.9 d, and consists of two nearly identical A1 V stars, each of mass ~2.7 M_sun. The physical parameters of the A stars, combined with evolutionary tracks, show that both are in the short-lived "blue-hook" evolutionary phase that occurs between the main sequence and the Hertzsprung gap, and that the age of the system is about 520 Myr. One puzzle is that the stars' rotational velocities are different from each other, and considerably slower than synchronous with the orbital period. It is possible that the center-of-mass velocity of the eclipsing pair is varying with time, suggesting that there is an unseen third orbiting body in the system. We propose a scenario in which the system began as a hierarchical triple, consisting of a ~2.9 M_sun star orbiting the close pair of A stars. Upon reaching the AGB stage, the primary engulfed the pair into a common envelope, leading to a rapid contraction of the orbit and catastrophic ejection of the envelope into the orbital plane. In this picture, the exposed core of the initial primary is now a white dwarf of ~0.7 M_sun, orbiting the eclipsing pair, which has already cooled below the detectability possible by IUE at our derived distance of 2.3 kpc and a reddening of E(B-V)=0.40. The SuWt2 system may be destined to perish as a Type Ia supernova. (Abridged)

description: An efficient scheme to compute the geometric entanglement per lattice site for quantum many-body systems on a periodic finite-size chain is proposed in the context of a tensor network algorithm based on the matrix product state representations. It is systematically tested for three prototypical critical quantum spin chains, which belong to the same Ising universality class. The simulation results lend strong support to the previous claim [Q.-Q. Shi, R. Orús, J. O. Fjærestad, and H.-Q. Zhou, New J. Phys \textbf{12}, 025008 (2010); J.-M. Stéphan, G. Misguich, and F. Alet, Phys. Rev. B \textbf{82}, 180406R (2010)] that the leading finite-size correction to the geometric entanglement per lattice site is universal, with its remarkable connection to the celebrated Affleck-Ludwig boundary entropy corresponding to a conformally invariant boundary condition.

description: Abstract:
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

description: Cold fronts (CFs) are found in most galaxy clusters, as well as in some galaxies and groups of galaxies. We propose that some CFs are relics of merging between two shocks propagating in the same direction. Such shock mergers typically result in a quasi-spherical, factor ~1.4-2.7 discontinuity in density and in temperature. These CFs may be found as far out as the virial shock, unlike what is expected in other CF formation models. As a demonstration of this effect, we use one dimensional simulations of clusters and show that shock induced cold fronts form when perturbations such as explosions or mergers occur near the cluster's centre. Perturbations at a cluster's core induce periodic merging between the virial shock and outgoing secondary shocks. These collisions yield a distinctive, concentric, geometric sequence of CFs which trace the expansion of the virial shock.

description: Exploiting small-angle X-ray and neutron scattering (SAXS/SANS) on the same sample volume at the same time provides complementary nanoscale structural information in two different contrast situations. Unlike an independent experimental approach, the truly combined SAXS/SANS experimental approach ensures the exactness of the probed samples, particularly for in situ studies. Here, an advanced portable SAXS system that is dimensionally suitable for installation in the D22 zone of ILL is introduced. The SAXS apparatus is based on a Rigaku switchable copper/molybdenum microfocus rotating-anode X-ray generator and a DECTRIS detector with a changeable sample-to-detector distance of up to 1.6 m in a vacuum chamber. A case study is presented to demonstrate the uniqueness of the newly established method. Temporal structural rearrangements of both the organic stabilizing agent and organically capped gold colloidal particles during gold nanoparticle growth are simultaneously probed, enabling the immediate acquisition of correlated structural information. The new nano-analytical method will open the way for real-time investigations of a wide range of innovative nanomaterials and will enable comprehensive in situ studies on biological systems. The potential development of a fully automated SAXS/SANS system with a common control environment and additional sample environments, permitting a continual and efficient operation of the system by ILL users, is also introduced.

description: We use a density-functional-theory (DFT) approach with a modified Becke-Johnson exchange plus local density approximation (LDA) correlation potential (mBJLDA) [semi-local, orbital-independent, producing accurate semiconductor gaps. see F. Tran and P. Blaha, Phys. Rev. Lett. 102, 226401 (2009)] to investigate the electronic structures of zincblende transition-metal (TM) pnictides and chalcogenides akin to semiconductors. Our results show that this potential does not yield visible changes in wide TM d-t_{2g} bands near the Fermi level, but makes the occupied minority-spin p-bands lower by 0.25~0.35 eV and the empty (or nearly empty) minority-spin e_g bands across the Fermi level higher by 0.33~0.73 eV. Consequently, mBJLDA, having no atom-dependent parameters, makes zincblende MnAs become a truly half-metallic (HM) ferromagnet with a HM gap (the key parameter) 0.318eV, being consistent with experiment. For zincblende MnSb, CrAs, CrSb, CrSe, or CrTe, the HM gap is enhanced by 19~56% compared to LDA and generalized gradient approximation results. The improved HM ferromagnetism can be understood in terms of the mBJLDA-enhanced spin exchange splitting.

Electron doped Ca10(Pt3As8)(Fe2As2)5 and Ca10(Pt4As8)(Fe2As2)5 - High Tc superconductors with skutterudite intermediary layers

description: It has been argued that the very high transition temperatures of the highest Tc cuprate superconductors are facilitated by enhanced CuO2 plane coupling through the (Bi,Tl,Hg)-O intermediary layers. Whether enhanced coupling through intermediary layers can also influence Tc in the iron arsenide superconductors has never been tested due the lack of appropriate systems for study. Here we report the crystal structures and properties of two iron arsenide superconductors, Ca10(Pt3As8)(Fe2As2)5 (the 10-3-8 phase) and Ca10(Pt4As8)(Fe2As2)5 (the 10-4-8 phase). Based on -Ca-(PtnAs8)-Ca-Fe2As2- layer stacking, the most important difference in the structures lies in the structural and electronic characters of the intermediary platinum arsenide layers. Electron doping through partial substitution of Pt for Fe in the Fe2As2 layers leads to Tc of 11 K in the 10-3-8 phase and 25 K in the 10-4-8 phase. Using the chemical concepts of Zintl ion electron counting and the stability of Pt in the 5d8 configuration we argue that the dramatic difference in Tc arises because the intermediary layer is semiconducting in the 10-3-8 phase but metallic in the 10-4-8 phase, leading to enhanced interlayer coupling in the 10-4-8 phase. The results suggest that metallic intermediary layers may offer a new road to higher Tc in iron arsenide superconductors.
Impact Experiment on Gneiss: The Effects of Foliation on Cratering Process

description: Two impact experiments were carried out on blocks of Maggia gneiss to assess the influence of mechanical target anisotropies on the cratering process. The experiments were done within the framework of Multidisciplinary Experimental and Modeling Impact Research Network. In one experiment the metamorphic foliation was vertical, that is, oriented perpendicular to the target surface, and in the other horizontal, that is, parallel to the target surface. This study reveals that due to preferred spallation along the foliation, the cratering efficiency is higher if the foliation is horizontal. The study further presents a comprehensive quantitative strain analysis in the subsurface of these craters. We use biotite kink bands as strain markers. The distribution of strain differs strongly in both experiments. If the foliation is vertical, the area beneath the central crater floor shows a high compressive strain. This is attributed to the ability of biotite to kink more easily when shortened parallel to its basal plane. If the foliation is horizontal, surface kinking is reduced and tensile failure along the foliation deepens the crater during unloading.
Signaling Legitimacy: Why Mixed-Gender Coalitions Outperform Single-Gender Coalitions in Advocating for Gender Equity

description:
Employees often engage in collective grassroots efforts to bring about gender equity in the workplace. Such coalition-based advocacy is largely driven by women, which has led to debate about whether men’s involvement as allies can help. Integrating literatures on signaling and legitimacy, we propose that the demographic composition of a gender equity advocacy coalition matters: men-only groups lack “coalition legitimacy,” or the perception that they are the “right” spokespersons for gender equity issues, whereas women-only groups struggle to convey “issue legitimacy,” or the perception that gender equity is of strategic importance within business organizations. By contrast, mixed-gender coalitions signal both forms of legitimacy, and are thus uniquely effective. We demonstrate these effects over three studies: managers reporting on advocacy coalitions comprising their colleagues (Study 1), an audio-based study showing that the proposed effects are unique for gender equity issues (Study 2), and a stimulus sampling study involving multiple policy proposals (Study 3). Our findings highlight the different forms of legitimacy that women and men bring to the table when selling gender equity issues. We discuss implications for who should be recruited to gender equity advocacy coalitions, and why.
