Assessing the Effectiveness of E-Recruitment Efforts in State Government

This study provides an evaluative framework for state e-recruitment efforts. Challenged bv the impending retirement of the baby boomer generation, public employers are implementing innovative hiring practices to aid in the recruitment of a new, talented workforce. Web-based recruitment offers an opportunity for state recruiters to reach a broader pool of job seeker talent. An effective framework for assessing the adequacy of state hiring websites would establish a set of criteria to aid in the development and implementation of state e-recruitment efforts. The framework is based on a literature review of relevant recruitment strategies in the public and private sector, featuring Content and Usability as the two foundational criteria for e-recruitment success. Two analysts apply this framework, developed to accurately measure the extent to which state hiring websites serve as a tool for attracting job applications, to all fifty state erecruitment efforts over a one year period. After gathering and quantifying the results, the data are correlated to critical hiring figures provided by state personnel departments in the 2008 iteration of the Government Performance Project. Correlations related to the percentage of employees leaving in the probationary period and applications per job opening demonstrate the relevance of the evaluation framework in relation to recruitment effectiveness. As a way of promoting best practices in state e-recruitment, the findings of the study highlight key innovations in existing hiring websites as a model for underdeveloped state recruitment efforts and demonstrate the potential benefits of developing an effective state e-recruitment effort

Photoinduced infrared activity in polyacetylene

Journal ArticlePhotoexcitation of trans - but not cis -polyacetylene, results in the appearance of strongly-ir-active local modes at 1370 and 1260 cm-1. This observation demonstrates that the photogeneration of self-localized charge carriers is unique to the trans isomer. In spite of their localization the kinetic mass of these photocarriers is small, Mc ≈ (1-2.5)m, a result which is in quantitative agreement with calculations based on single-chain models

Phase control of magnons in the van der Waals antiferromagnet NiPS3_3

We demonstrate phase control of magnons in the van der Waals antiferromagnet NiPS$_3$ using optical excitation by polarized light. The sign of the coherent precession of spin amplitude changes upon (1) reversing the helicity of a circularly polarized pump beam, or (2) rotating the polarization of a linearly polarized pump by $\pi/2$. Because these two excitation pathways have comparable generation efficiency, the phase of spin precession can be continuously tuned from 0 to $2\pi$ by controlling the polarization state of the pump pulse. The ability to excite magnons with a desired phase has potential applications in the design of a spin-wave phased array and ultrafast spin information processing

Postmission Altruistic Identity Disruption Questionnaire (PostAID/Q): identifying humanitarian-related distress during the reintegration period following international humanitarian aid work

Psychological care of humanitarian personnel exposed to high risk environments is not standardized across the sector. Particularly, returnees experiencing re-integration distress specific to prior aid deployment, is randomly addressed. The Postmission Altruistic Identity Disruption Questionnaire (PostAID/Q), an 18-item self-report screening tool, attempts to standardize assessment of re-integration/specific distress in returnees from humanitarian deployment. When individuals, high in altruistic identity (AI), perceive invalidation or lack of support from organization, family, or society following a difficult deployment, they may experience altruistic identity disruption (AID) manifest by interrelated feelings of isolation, doubt, and self-blame. Paradoxically, AID distress can precipitate attempts to redeploy prematurely leaving any prior adverse/traumatic responses unresolved. This study compared the discriminant validity of PostAID/Q with standardized measures of distress and social support (IES-R;GHQ-12;SPS). The construct demonstrated significant predictive value, high internal consistency and significant variance over and above the other constructs. Promisingly, PostAID/Q shows utility in predicting re-integration/specific distress postmission

Imaging anomalous nematic order and strain in optimally doped BaFe2_2(As,P)2_2

We present the strain and temperature dependence of an anomalous nematic phase in optimally doped BaFe$_2$(As,P)$_2$. Polarized ultrafast optical measurements reveal broken 4-fold rotational symmetry in a temperature range above $T_c$ in which bulk probes do not detect a phase transition. Using ultrafast microscopy, we find that the magnitude and sign of this nematicity vary on a ${50{-}100}~\mu$m length scale, and the temperature at which it onsets ranges from 40 K near a domain boundary to 60 K deep within a domain. Scanning Laue microdiffraction maps of local strain at room temperature indicate that the nematic order appears most strongly in regions of weak, isotropic strain. These results indicate that nematic order arises in a genuine phase transition rather than by enhancement of local anisotropy by a strong nematic susceptibility. We interpret our results in the context of a proposed surface nematic phase

Spin wavepackets in the Kagome ferromagnet Fe3_3Sn2_2: propagation and precursors

The propagation of spin waves in magnetically ordered systems has emerged as a potential means to shuttle quantum information over large distances. Conventionally, the arrival time of a spin wavepacket at a distance, $d$, is assumed to be determined by its group velocity, $v_g$. He we report time-resolved optical measurements of wavepacket propagation in the Kagome ferromagnet Fe$_3$Sn$_2$ that demonstrate the arrival of spin information at times significantly less than $d/v_g$. We show that this spin wave "precursor" originates from the interaction of light with the unusual spectrum of magnetostatic modes in Fe$_3$Sn$_2$. Related effects may have far-reaching consequences toward realizing long-range, ultrafast spin wave transport in both ferromagnetic and antiferromagnetic systems.Comment: 17+12 pages, 5+4 figure

Linear magneto-conductivity as a DC probe of time-reversal symmetry breaking

Several optical experiments have shown that in magnetic materials the principal axes of response tensors can rotate in a magnetic field. Here we offer a microscopic explanation of this effect, and propose a closely related DC transport phenomenon -- an off-diagonal \emph{symmetric} conductivity linear in a magnetic field, which we refer to as linear magneto-conductivity (LMC). Although LMC has the same functional dependence on magnetic field as the Hall effect, its origin is fundamentally different: LMC requires time-reversal symmetry to be broken even before a magnetic field is applied, and is therefore a sensitive probe of magnetism. We demonstrate LMC in three different ways: via a tight-binding toy model, density functional theory calculations on MnPSe$_3$, and a semiclassical calculation. The third approach additionally identifies two distinct mechanisms yielding LMC: momentum-dependent band magnetization and Berry curvature. Finally, we propose an experimental geometry suitable for detecting LMC, and demonstrate its applicability using Landauer-B\"{u}ttiker simulations. Our results emphasize the importance of measuring the full conductivity tensor in magnetic materials, and introduce LMC as a new transport probe of symmetry.Comment: 6+8 pages, 4+3 figure
