Death education in nursing and medical curricula : an integrative literature review
Creators: name: Powar, Amardeep
Publisher: name: University of British Columbia
Year: 2015

description: Death is an inevitable experience for each individual. Although death is a natural human experience, the avoidance of death is an issue in the culture at large. This isolation of death and dying also is evident in the health professions of nursing and medicine. Despite the fact that death and dying has received considerably more scholarly attention over time, relatively little attention has been given to the topic of death education. This study explores the literature on death education within nursing and medicine from the 1970s onwards. Using an integrative literature review, scholarly articles were reviewed to determine how death education is enacted or made real in the health care environment, particularly in the nursing and medical curricula. This study examines how educators have taught the topic of death and dying over time and how an analysis of these past experiences may inform current education on death related concepts within health professional fields. The lack of attention to death and dying in nursing and medical curricula affects the confidence and competence that health care professionals have in managing these situations. Although death is a common occurrence in the health care environment, there remains a gap in how educators are supported to teach these concepts to students. The analysis of scholarly literature from the 1970s until the present reveals three themes. The avoidance of death in the culture at large, the importance of psychosocial aspects of care, and the lack of support for educators are three over-arching themes. The main recommendations for educators teaching death related topics appearing in the literature reviewed center on ensuring student contact with terminally ill and dying patients in the clinical setting as a way to learn about the dying process, use of simulation based learning, encouraging collaboration amongst the interdisciplinary team to meet patient and family needs, and the use of explicit competencies related to end-of-life care to ensure consistency amongst all students. The findings from this review are relevant for student learning, educator preparation, and may also influence how educators in the health professions incorporate death and dying concepts into their curricula.

description: Gaussian measures of Gibbsian type are associated with some shell models of 3D turbulence; they are constructed by means of the energy, a conserved quantity for the 3D inviscid and unforced shell model. We prove the existence of a unique global flow for a stochastic viscous shell model and a global flow for the deterministic inviscid shell model, with the property that these Gibbs measures are invariant for these flows.

description: We prove the universality of the generalized QDD_{N1,N2} (quadratic dynamical decoupling) pulse sequence for near-optimal suppression of general single-qubit decoherence. Earlier work showed numerically that this dynamical decoupling sequence, which consists of an inner Uhrig DD (UDD) and outer UDD sequence using N1 and N2 pulses respectively, can eliminate decoherence to O(T^N) using O(N^2) unequally spaced "ideal" (zero-width) pulses, where T is the total evolution time and N=N1=N2. A proof of the universality of QDD has been given for even N1. Here we give a general universality proof of QDD for arbitrary N1 and N2. As in earlier proofs, our result holds for arbitrary bounded environments. Furthermore, we explore the single-axis (polarization) error suppression abilities of the inner and outer UDD sequences. We analyze both the single-axis QDD performance and how the overall performance of QDD depends on the single-axis errors. We identify various performance effects related to the parities and relative magnitudes of N1 and N2. We prove that using QDD_{N1,N2} decoherence can always be eliminated to O(T^min[N1,N2]).

ELECTRONEUROMYOGRAPHY IN EARLY STAGE DIAGNOSTICS  OF POLYNEUROPATHY
Creators: name: Kodirova, Nargizakhon
Publisher: name: Zenodo
Year: 2025

description: The problem of diabetic distal polyneuropathy (DDPN) is preconditioned by its great prevalence, according to specialized studies data, late diagnostics and serious consequences. The importance of DDPN diagnostics at its early stage doesn't generate doubts: just at this period disturbance of peripheral nerves is of reciprocal nature and the therapy is effective to the maximum degree. But the objectification of the DDPN diagnosis is difficult: the data of neurologic and electrophysiolog-ical tests often do not correspond to the clinical symptoms and signs as these methods evaluate lesions of large nervous fibers whereas in DDPN it's small fibers that are damaged in the first place. Use of skin biopsy and confocal corneal microscopy for evaluation of small fibers is extremely restricted in a clinical practice. Possibilities of electroneuromyography (ENMG) are analyzed as an option: parameters with their subjective peculiarities, selection of nerves and their number for DDPN diagnostics as a context of topographic neurology and neurophysiology of distal fibers.

description: We analysed whole-rock major and trace elements and Sr-Nd-Pb-Hf isotopes of the late Cenozoic volcanic rocks in the Leizhou Peninsula, South China to investigate their mantle source characteristics. These volcanic rocks, collected from Jiujiang, Tianyang and Huoju areas of the Leizhou Peninsula, are characterized by incompatible element enrichment but variable isotopic depletion. The volcanic rocks from Jiujiang and Tianyang show prominent primitive-mantle-normalized positive Nb, Ta and Sr anomalies and depleted Sr-Nd-Pb-Hf isotope compositions, whereas those from Huoju show slight positive to negative Nb and Ta anomalies, a prominent positive Pb anomaly, and more enriched Sr-Nd-Pb-Hf isotope compositions. Two types of mantle metasomatism are required to explain the geochemical characteristics of these rocks. The Jiujiang and Tianyang samples were largely derived from a mantle source metasomatized recently by a low-F melt. Such low-F melt is generated within the asthenospheric mantle, which is enriched in volatiles and incompatible elements with positive Sr anomaly and depleted Sr-Nd-Pb-Hf isotope compositions. The Huoju samples were largely derived from a mantle source metasomatized by recycled upper continental crust material. These two types of mantle metasomatism beneath the Leizhou Peninsula are consistent with trace element characteristics of mantle mineralogy (e.g. clinopyroxene vs. amphibole), which reflects source evolution in space and time (e.g. tectonic setting change).

description: We consider molecular communication, with information conveyed in the time of release of molecules. The main contribution of this paper is the development of a theoretical foundation for such a communication system. Specifically, we develop the additive inverse Gaussian (IG) noise channel model: a channel in which the information is corrupted by noise with an inverse Gaussian distribution. We show that such a channel model is appropriate for molecular communication in fluid media - when propagation between transmitter and receiver is governed by Brownian motion and when there is positive drift from transmitter to receiver. Taking advantage of the available literature on the IG distribution, upper and lower bounds on channel capacity are developed, and a maximum likelihood receiver is derived. Theory and simulation results are presented which show that such a channel does not have a single quality measure analogous to signal-to-noise ratio in the AWGN channel. It is also shown that the use of multiple molecules leads to reduced error rate in a manner akin to diversity order in wireless communications. Finally, we discuss some open problems in molecular communications that arise from the IG system model.

description: Present-days Reversed Field Pinches (RFPs) are characterized by quasi-laminar magnetic configurations in their core, whose boundaries feature sharp internal transport barriers, in analogy with tokamaks and stellarators. The abatement of magnetic chaos leads to the reduction of associated particle and heat transport along wandering field lines. At the same time, the growth of steep temperature gradients may trigger drift microinstabilities. In this work we summarize the work recently done in the RFP RFX-mod in order to assess the existence and the impact upon transport of such electrostatic and electromagnetic microinstabilities as Ion Temperature Gradient (ITG), Trapped Electron Modes (TEM) and microtearing modes.

description: Purpose To examine racial–ethnic variation in adherence to established quality metrics (NCCN guidelines and ASCO quality metrics) for breast cancer, accounting for individual-, facility-, and area-level factors. Methods Data from women diagnosed with invasive breast cancer at 66+ years of age from 2000 to 2017 were examined using SEER-Medicare. Associations between race and ethnicity and guideline-concordant diagnostics, locoregional treatment, systemic therapy, documented stage, and oncologist encounters were estimated using multilevel logistic regression models to account for clustering within facilities or counties. Results Black and American Indian/Alaska Native (AIAN) women had consistently lower odds of guideline-recommended care than non-Hispanic White (NHW) women (Diagnostic workup: ORBlack 0.83 (0.79–0.88), ORAIAN 0.66 (0.54–0.81); known stage: ORBlack 0.87 (0.80–0.94), ORAIAN 0.63 (0.47–0.85); seeing an oncologist: ORBlack 0.75 (0.71–0.79), ORAIAN 0.60 (0.47–0.72); locoregional treatment: ORBlack 0.80 (0.76–0.84), ORAIAN 0.84 (0.68–1.02); systemic therapies: ORBlack 0.90 (0.83–0.98), ORAIAN 0.66 (0.48–0.91)). Commission on Cancer accreditation and facility volume were significantly associated with higher odds of guideline-concordant diagnostics, stage, oncologist visits, and systemic therapy. Black residential segregation was associated with significantly lower odds of guideline-concordant locoregional treatment and systemic therapy. Rurality and area SES were associated with significantly lower odds of guideline-concordant diagnostics and oncologist visits. Conclusions This is the first study to examine guideline-concordance across the continuum of breast cancer care from diagnosis to treatment initiation. Disparities were present from the diagnostic phase and persisted throughout the clinical course. Facility and area characteristics may facilitate or pose barriers to guideline-adherent treatment and warrant future investigation as mediators of racial–ethnic disparities in breast cancer care.

description: It is suggested that low dimensionality can improve the thermoelectric (TE) power factor of a device, offering an enhancement of the ZT figure of merit. In this work the atomistic sp3d5s*-spin-orbit-coupled tight-binding model and the linearized Boltzmann transport theory is applied to calculate the room temperature electrical conductivity, Seebeck coefficient, and power factor of narrow 1D silicon nanowires (NWs). We present a comprehensive analysis of the thermoelectric coefficients of n-type and p-type NWs of diameters from 12nm down to 3nm, in [100], [110], and [111] transport orientations at different carrier concentrations. We find that the length scale at which the influence of confinement on the power factor can be observed is at diameters below 7nm. We show that contrary to the current view, the effect of confinement and geometry on the power factor originates mostly from changes in the conductivity which is strongly affected, rather than the Seebeck coefficient. In general, enhanced scattering at these diameter scales strongly degrades the conductivity and power factor of the device. We identify cases, however, for which confinement largely improves the channel's conductivity, resulting in ~2-3X power factor improvements. Our results may provide guidance in the design of efficient low dimensional thermoelectric devices.

description: Black hole masses for samples of active galactic nuclei (AGN) are currently estimated from single-epoch optical spectra. In particular, the size of the broad-line emitting region needed to compute the black hole mass is derived from the optical or ultraviolet continuum luminosity. Here we consider the relationship between the broad-line region size, R, and the near-infrared (near-IR) AGN continuum luminosity, L, as the near-IR continuum suffers less dust extinction than at shorter wavelengths and the prospects for separating the AGN continuum from host-galaxy starlight are better in the near-IR than in the optical. For a relationship of the form R propto L^alpha, we obtain for a sample of 14 reverberation-mapped AGN a best-fit slope of alpha=0.5+/-0.1, which is consistent with the slope of the relationship in the optical band and with the value of 0.5 naively expected from photoionisation theory. Black hole masses can then be estimated from the near-IR virial product, which is calculated using the strong and unblended Paschen broad emission lines (Pa alpha or Pa beta).

Justice and inclusion in global politics : victim representation and the International Criminal Court
Creators: name: Tenove, Christopher John
Publisher: name: University of British Columbia
Year: 2015

description: There are widespread concerns that those people who ought to benefit from global governance are instead ignored, disempowered or harmed by it. Central to these concerns, this dissertation argues, is the principle of inclusion. Bringing together normative and empirical inquiry, this dissertation explains why inclusion matters and how it might be achieved in global governance, and uses this approach to assess the oft-criticized relationship between the International Criminal Court (ICC) and victims of international crimes. Inclusion is crucial for both justice and democratic legitimacy. Inclusion can empower constituencies to address injustices they face and negotiate what justice should entail. Inclusion is also necessary to address democratic deficits in global governance, when constituencies are excluded from decision-making processes that significantly affect them. The complexity and large scale of global governance make inclusion difficult to conceptualize and promote. Building on democratic theory, this dissertation proposes the framework of mediated inclusion, which identifies the key activities of representation and communication needed for constituencies to understand and influence decision-making. It then engages with International Relations scholarship to identify actors, institutional design features and contexts that can promote or frustrate the inclusion of the intended beneficiaries of global governance. This analysis reveals both persistent challenges and positive trends in opportunities for inclusion at international organizations. These insights are used to assess the inclusion of victims in the creation and operations of the ICC. This analysis draws on over 100 interviews with ICC staff, state officials and civil society members, as well as focus groups with survivors of violence in Uganda and Kenya. Close examination of negotiations to create the ICC reveals how advocates for victims’ rights achieved a strong legal framework for victim inclusion. Case studies of the ICC’s interventions in Uganda and Kenya evaluate diverse advocates for victims, and identify opportunities and limitations for victim inclusion in judicial, bureaucratic and diplomatic decision-making sites. Contributing to debates on global democracy, transnational advocacy, international organization design and international criminal justice, this dissertation shows how the principle of inclusion can be used to critically assess global governance and to create institutions that are more legitimate and just.

description: A tension increment after sputter deposition of 1 nm of WSi2 onto sputtered Si was observed at low Ar gas pressures. Wafer curvature data on multilayers were found to have a periodic variation corresponding to the multilayer period, and this permitted statistical analyses to improve the sensitivity to small stresses. The observation of tension instead of compression in the initial stage of growth is new and a model invoking surface rearrangement is invoked. The data also bear on an unusual surface smoothing phenomena for sputtered Si surfaces caused by the sputter deposition of WSi2 . We furthermore report that for low Ar pressures the Si layers are the predominant source of built-up stress.

Our breadboard including 8 telescopes is firstly tested in a manual cophasing configuration on a 1D object. The Point Spread Function (PSF) is measured and exhibits a dynamics in the range of 300. A quantitative analysis of the potential biases demonstrates that this limitation is related to the residual phase fluctuation on each interferometric arm. Secondly, an unbalanced binary star is imaged demonstrating the imaging capability of THT. In addition, 2D PSF is recorded even if the telescope array is not optimized for this purpose.

We re-examine the classification of these super-Jeans cores using Spitzer maps and find that 3 are re-classified as protostellar, 11 have ambiguous emission near the core positions, and 3 appear to be genuinely starless. We suggest the 3 starless and 11 undetermined super-Jeans cores represent excellent targets for future observational and computational study to understand the evolution of dense cores and the process of star formation.

description: The Seyfert 1 galaxy Zw 229-015 is among the brightest active galaxies being monitored by the Kepler mission. In order to determine the black hole mass in Zw 229-015 from H-beta reverberation mapping, we have carried out nightly observations with the Kast Spectrograph at the Lick 3m telescope during the dark runs from June through December 2010, obtaining 54 spectroscopic observations in total. We have also obtained nightly V-band imaging with the Katzman Automatic Imaging Telescope at Lick Observatory and with the 0.9m telescope at the Brigham Young University West Mountain Observatory over the same period. We detect strong variability in the source, which exhibited more than a factor of 2 change in broad H-beta flux. From cross-correlation measurements, we find that the H-beta light curve has a rest-frame lag of 3.86(+0.69,-0.90) days with respect to the V-band continuum variations. We also measure reverberation lags for H-alpha and H-gamma and find an upper limit to the H-delta lag. Combining the H-beta lag measurement with a broad H-beta width of sigma = 1590+/-47 km/s measured from the root-mean-square variability spectrum, we obtain a virial estimate of M_BH = 1.00(-0.24,+0.19)*10^7 solar masses for the black hole in Zw 229-015. As a Kepler target, Zw 229-015 will eventually have one of the highest-quality optical light curves ever measured for any active galaxy, and the black hole mass determined from reverberation mapping will serve as a benchmark for testing relationships between black hole mass and continuum variability characteristics in active galactic nuclei.

description: The stellar system omega Centauri is well known for the large range in abundance among its member stars. Recent work has indicated that the globular cluster M22 (NGC 6656) also possesses an internal abundance range, albeit substantially smaller than that in omega Cen. Here we compare, as a function of [Fe/H], element-to-iron ratios in the two systems for a number of different elements using data from abundance analyses of red giant branch stars. It appears that the nucleosynthetic enrichment processes were very similar in these two systems despite the substantial difference in total mass.

Quark nugget dark matter : cosmic evidence and detection potential
Creators: name: Lawson, Kyle
Publisher: name: University of British Columbia
Year: 2015

description: I present a dark matter model in which the dark matter is composed of very heavy “nuggets” of Standard Model quarks and antiquarks. This model was originally motivated by the fact that the matter and dark matter mass densities are observed to have similar scales. If these two forms of matter originate through completely distinct physical processes then their densities could easily have existed at vastly different scales. However, if the dark and the visible matter are co-produced, this similarity in scales is a natural outcome. In the model considered here dark matter and the baryonic matter share an origin in Standard Model strong force physics. The main goal of this work is to establish the testable predictions of this model. The physical properties of the nuggets are set by well understood nuclear physics and quantum electrodynamics, allowing many observable consequences to be predicted. To this end, I devote special attention to the structure of the surface layer of the nuggets from which the majority of observable consequences arise. With this basic picture of nugget structure in place, I will discuss the consequences of their interactions with a number of different environments. Particular attention is given to the galactic centre and to the early universe, as both are sufficiently dense to allow for significant levels of matter-dark matter interaction. The emitted radiation, in both cases, is shown to be consistent with observations. Finally, I discuss the consequences of a nugget striking the earth. In this context, I will demonstrate that the nuggets produce effects observable in cosmic ray detectors. Based on these considerations, I discuss the nugget detection potential for experiments primarily devoted to the study of high energy cosmic rays.

description: Two-dimensional polar liquid crystals have been discovered recently in monolayers of anisotropic molecules. Here, we provide a systematic theoretical description of liquid-crystalline phases for polar particles in two spatial dimensions. Starting from microscopic density functional theory, we derive a phase-field-crystal expression for the free-energy density which involves three local order-parameter fields, namely the translational density, the polarization, and the nematic order parameter. Various coupling terms between the order-parameter fields are obtained which are in line with macroscopic considerations. Since the coupling constants are brought into connection with the molecular correlations, we establish a bridge from microscopic to macroscopic modeling. Our theory provides a starting point for further numerical calculations of the stability of polar liquid-crystalline phases and is also relevant for modeling of microswimmers which are intrinsically polar.

Where Else To Go? Worldbuilding in the Work of Black Gender Non-Conforming Poets
Creators: name: Purcell, Blaine

Year: 2025

description:
What can we learn from the ways Black queer gender non-conforming people create their own spaces of belonging? In Disidentifications: Queers of Color and the Performance of Politics, Jose Esteban Muñoz (1999) states that Black queer people must “read [themselves] and [their] own life narrative” in a dominant sphere “that is not culturally coded to connect” with their identities (12). In the poetic form, Kopano Maroga, Aurielle Marie, and Alan Peleaz Lopez use their life narratives to create worlds that expand beyond the bounds created by oppressive systems in order to include themselves and their communities. This article explores the poets’ backgrounds and poetry in order to understand what constitutes safety for Black queer gender non-conforming people and what the public must change to achieve that safety. Further, the article explores each poet’s place of origin and upbringing, and how these inform the type of world they would like to see. This research aims to serve as a guide for considering how the worldbuilding done by Black gender non-conforming poets can be applied to our material reality.

description: This session aims to bring together interested people from all over the world to talk about PIDs in practice-based arts research. It will start with a brief case study on the experience at the University of Westminster, based in London in the UK, who engaged with their practice-based arts research community (and supplier Haplo) to develop their new open source repository software to identify what this research looks like and how the repository could better reflect it. We will then highlight how various Persistent Identifiers don’t quite fit the practice-research landscape – or where they could do, how and where practitioners require more specific guidance that addresses practice research. Without this, the many benefits of the PID graph/landscape are not available to the practice-based research community. The specific examples we will cover include: ORCID iDs, DOIs, RAID and the CRediT taxonomy.

Manipulation of the Dirac cones and the anomaly in the graphene related quantum Hall effect

description: The quantum Hall effect in graphene is regarded to be involving half-integer topological numbers associated with the massless Dirac particle, this is usually not apparent due to the doubling of the Dirac cones. Here we theoretically consider two classes of lattice models in which we manipulate the Dirac cones with either (a) two Dirac points that have mutually different energies, or (b) multiple Dirac cones having different Fermi velocities. We have shown, with an explicit calculation of the topological (Chern) number for case (a) and with an adiabatic argument for case (b) that the results are consistent with the picture that a single Dirac fermion contributes the half-odd integer series (... -3/2, -1/2, 1/2, 3/2, ...) to the Hall conductivity when the Fermi energy traverses the Landau levels.

Turning the Street Into the Dancefloor: A Comparative Analysis on Urban Space Creation via Jamaican Dancehall and Brazilian Funk
Creators: name: McFarlane, Simone
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2025

description:
This article examines Jeffrey Hou’s (2020) concept of “guerrilla urbanism,” as embodied by Jamaican dancehall and Brazilian funk, two influential music cultures that resist spatial and social marginalization. Emerging from the economically disadvantaged neighborhoods of Kingston and Rio de Janeiro, dancehall and funk allow for insights into how dance music cultures function as a tool for asserting agency and reclaiming urban space. Both genres developed during times of severe political and economic crisis, when their respective communities were grappling with state neglect, violence, and racial and class-based discrimination. Dancehall and funk, characterized by loud, booming sound systems and provocative lyrics, transcend the physical boundaries imposed by urban planning and social exclusion. These music scenes foster powerful, communal spaces—street parties, sound clashes, and baile funk gatherings—where marginalized communities reclaim the right to public life, visibility, and celebration. The article argues that the sonic disruptions created by dancehall and funk operate as acts of guerrilla urbanism, offering alternative ways of inhabiting and experiencing the city. Through this lens, the article demonstrates how these dance music cultures function not only as cultural expression but also as a form of resistance against the state’s attempts to control public space and silence marginalized voices. By comparing the cultural evolution of both genres and their impact on urban life, the article highlights how music surpasses entertainment, becoming a critical medium for political expression and spatial transformation, and amplifying the voices of communities that are denied their right to the city.
Anti-Stokes fluorescence spectroscopy and imaging for cutaneous porphyrin detection
Creators: name: Tian, Yunxian
Publisher: name: University of British Columbia
Year: 2015

description: Porphyrins produced by Propionibacterium acnes represent the principal fluorophore associated with acne, and appear as orange-red luminescence under the Wood’s lamp. Assessment of acne based on Wood’s lamp (UV) or visible (VIS) light illumination is limited by photon penetration depth and has limited sensitivity for earlier stage lesions. Inducing fluorescence with near infrared (NIR) excitation may provide an alternative way to assess porphyrin-related skin disorders. The objectives of this thesis are (1) to design and develop an optical instrument that perform anti-Stokes fluorescence spectroscopy and imaging measurements under continuous wave CW laser excitation as well as multiphoton fluorescence spectroscopy and imaging under femtosecond (fs) pulsed laser excitation; and (2) using this system for regular (Stokes) fluorescence measurements to evaluate and compare sebum-associated porphyrin fluorescence properties. A NIR multi-modality fluorescence imaging system with fluorescence spectroscopy capability was constructed. The switchable output from a tunable Ti : Sapphire femtosecond (fs) laser (720-950nm) or a (CW) laser (785nm) was scanned over the objective lens. Co-registered confocal imaging and fluorescence (anti-stokes fluorescence & two-photon fluorescence) imaging were acquired in video rate. Under 785 nm CW laser excitation PpIX powder exhibited anti-Stokes fluorescence with an intensity that was linearly dependent on the excitation power and a red spectral emission of 650-720 nm, while the fs laser excited two-photon excitation fluorescence showed a quadratic dependency. Anti-Stokes fluorescence of psoriasis scale image and ex vivo human nasal skin, skin surface smears from the nose, and ex vivo sebum secretions was obtained by the same system configuration. Regular (Stokes) fluorescence was presented under UV and visible light excitation on ex vivo nasal skin and sebum secretions from non-inflamed acne, but not on skin surface smears from the nose or sebum secretions from inflamed acne. In conclusion, anti-Stokes fluorescence under NIR CW excitation is more sensitive and specific for porphyrins than UV or visible light-excited regular (Stokes) fluorescence and fs laser-excited multi-photon fluorescence. The anti-Stokes fluorescence of porphyrins within sebum could potentially be applied to detecting and targeting acne lesions for treatment via fluorescence image guidance.

description: We identify the presence of Pet-Fish problem situations and the corresponding Guppy effect of concept theory on the World-Wide Web. For this purpose, we introduce absolute weights for words expressing concepts and relative weights between words expressing concepts, and the notion of 'meaning bound' between two words expressing concepts, making explicit use of the conceptual structure of the World-Wide Web. The Pet-Fish problem occurs whenever there are exemplars - in the case of Pet and Fish these can be Guppy or Goldfish - for which the meaning bound with respect to the conjunction is stronger than the meaning bounds with respect to the individual concepts.

description: We describe SPIDER, a balloon-borne instrument to map the polarization of the millimeter-wave sky with degree angular resolution. Spider consists of six monochromatic refracting telescopes, each illuminating a focal plane of large-format antenna-coupled bolometer arrays. A total of 2,624 superconducting transition-edge sensors are distributed among three observing bands centered at 90, 150, and 280 GHz. A cold half-wave plate at the aperture of each telescope modulates the polarization of incoming light to control systematics. Spider's first flight will be a 20-30-day Antarctic balloon campaign in December 2011. This flight will map \sim8% of the sky to achieve unprecedented sensitivity to the polarization signature of the gravitational wave background predicted by inflationary cosmology. The Spider mission will also serve as a proving ground for these detector technologies in preparation for a future satellite mission.
