A Survey For Very Short-Period Planets In The Kepler Data, Brian Jackson, Christopher C. Stark, Elisabeth R. Adams, John Chambers, Drake Deming
A Survey For Very Short-Period Planets In The Kepler Data, Brian Jackson, Christopher C. Stark, Elisabeth R. Adams, John Chambers, Drake Deming
Brian Jackson
We conducted a search for very short-period transiting objects in the publicly available Kepler data set. Our preliminary survey has revealed four planetary candidates, all with orbital periods less than 12 hr. We have analyzed the data for these candidates using photometric models that include transit light curves, ellipsoidal variations, and secondary eclipses to constrain the candidates’ radii, masses, and effective temperatures. Even with masses of only a few Earth masses, the candidates’ short periods mean that they may induce stellar radial velocity signals (a few m s−1) detectable by currently operating facilities. The origins of such short-period planets are …
Barriers To Behavior-Based And Outcome-Based Evaluations Of Workplace Training, Perri Kennedy, Seung Youn Chyung
Barriers To Behavior-Based And Outcome-Based Evaluations Of Workplace Training, Perri Kennedy, Seung Youn Chyung
Seung Youn (Yonnie) Chyung
Most workplace learning professionals understand the need to evaluate the training interventions they develop for their organizations. A behavior-based evaluation examines the merit of the training and its relevance to organizational outputs, while a results-based evaluation measures actual outcomes against iexpected benefits. In short, did the training intervention meet its objectives, and did it have the desired impact on workplace performance? In this era of shrinking budgets, it's critical for learning departments to prove their value to their organizations. However, surveys reveal that only about half of workforce training interventions are evaluated on the on-the-job behaviors they generate, and even …

Bringing Teach For America Into The Forefront Of Teacher Education: Philanthropy Meets Spin, Kathleen P. Demarrais, Julianne Wenner, Jamie B. Lewis
Julianne Wenner
This study examines the practices utilized by TFA from its inception in 1990 to create its brand and how these practices have transformed TFA into a cultural icon within the national landscape of teacher education. Well-funded through both philanthropic foundations, corporate sponsorships, and federal monies, TFA’s use of its organizational and political networks, as well as the media, has enabled it to position itself discursively as a leader in the preparation of teachers in the U.S, resulting not only in transforming state and national discussions about teacher preparation, but in establishing a network of elites with a particular ideology of …
Measurement Of Spin-Orbit Misalignment And Nodal Precession For The Planet Around Pre-Main-Sequence Star Ptfo 8-8695 From Gravity Darkening, Jason W. Barnes, Julian C. Van Eyken, Brian K. Jackson, David R. Ciardi, Jonathan J. Fortney
Measurement Of Spin-Orbit Misalignment And Nodal Precession For The Planet Around Pre-Main-Sequence Star Ptfo 8-8695 From Gravity Darkening, Jason W. Barnes, Julian C. Van Eyken, Brian K. Jackson, David R. Ciardi, Jonathan J. Fortney
Brian Jackson
PTFO 8-8695b represents the first transiting exoplanet candidate orbiting a pre-main-sequence star (van Eyken et al. 2012, ApJ, 755, 42). We find that the unusual lightcurve shapes of PTFO 8-8695 can be explained by transits of a planet across an oblate, gravity-darkened stellar disk. We develop a theoretical framework for understanding precession of a planetary orbit’s ascending node for the case when the stellar rotational angular momentum and the planetary orbital angular momentum are comparable in magnitude. We then implement those ideas to simultaneously and self-consistently fit two separate lightcurves observed in 2009 December and 2010 December. Our two self-consistent …
Cross Cultural Competence For Libraries, Elizabeth Ramsey
Cross Cultural Competence For Libraries, Elizabeth Ramsey
Elizabeth Ramsey
As libraries struggle to recruit and retain staff members from underrepresented ethnic and cultural groups, alternative strategies must be advanced to more competently assess and meet the needs of the increasingly diverse American population in all aspects of librarianship. Training in cross cultural competency for all library staff may help libraries become more adept at serving their multiethnic patrons. This presentation will examine concepts in cross cultural awareness and how they can apply to libraries. Through cross cultural training we may gain the knowledge, understanding, attitudes and skills to overcome a variety of biases and assumptions. Overcoming these obstacles could …

Keynote Speaker - Simulation, Stimulation And Silence: Learning Online And Off, Norman Friesen
Norman Friesen
Almost 20 years after the popular adoption of the Internet, we are still finding out about the nature of online places and spaces. Whether these locations are used for interpersonal communication or naturalistic simulation, they offer characteristics which may be ideally suited to some types of pedagogical activities and less appropriate for others. This often depends on a deeper understanding of the nature of these activities and experiences. In this presentation Norm Friesen of Boise State University will undertake a careful examination of a couple of practical examples. He will use these examples explore the nature of both pedagogy and …
Floods Of The Mekong At Chiang Saen, Northern Thailand: Archaeological And Osl Dating Of Large Floods, Spencer H. Wood, Alan D. Ziegler, Tammy M. Rittenour
Floods Of The Mekong At Chiang Saen, Northern Thailand: Archaeological And Osl Dating Of Large Floods, Spencer H. Wood, Alan D. Ziegler, Tammy M. Rittenour
Spencer H. Wood
One meter and a half of floodplain sediment buries AD 14‐15th C brick temple ruins and cultural layers on the Laos floodplain of the Mekong, across from Chiang Saen Noi. Dark soil layers separating three flood‐sediment layers suggest the soils developed on sediment layers deposited by large floods. Little or no deposition occurs between such events. The upper flood layer was probably deposited by the September, 1966 flood that inundated Chiang Saen city to a depth of three meters, with maximum gage height reaching 13.82 m, and peak flow of 23,500 m3/s. In comparison, the depth of the August 2008 …
Associations Of Organic Produce Consumption With Socioeconomic Status And The Local Food Environment: Multi-Ethnic Study Of Atherosclerosis (Mesa), Cynthia L. Curl, Shirley A.A. Beresford, Anjum Hajat, Joel D. Kaufman, Kari Moore, Jennifer A. Nettleton, Ana V. Diez-Roux
Associations Of Organic Produce Consumption With Socioeconomic Status And The Local Food Environment: Multi-Ethnic Study Of Atherosclerosis (Mesa), Cynthia L. Curl, Shirley A.A. Beresford, Anjum Hajat, Joel D. Kaufman, Kari Moore, Jennifer A. Nettleton, Ana V. Diez-Roux
Cynthia Curl
Neighborhood characteristics, such as healthy food availability, have been associated with consumption of healthy food. Little is known about the influence of the local food environment on other dietary choices, such as the decision to consume organic food. We analyzed the associations between organic produce consumption and demographic, socioeconomic and neighborhood characteristics in 4,064 participants aged 53–94 in the Multi-Ethnic Study of Atherosclerosis using log-binomial regression models. Participants were classified as consuming organic produce if they reported eating organic fruits and vegetables either “sometimes” or “often or always”. Women were 21% more likely to consume organic produce than men (confidence …

Optimal Training Sequences For Joint Timing Synchronization And Channel Estimation In Distributed Communication Networks, Ali A. Nasir, Hani Mehrpouyan, Salman Durrani, Steven D. Blostein, Rodney A. Kennedy, Björn Ottersten
Hani Mehrpouyan
For distributed multi-user and multi-relay cooperative networks, the received signal may be affected by multiple timing offsets (MTOs) and multiple channels that need to be jointly estimated for successful decoding at the receiver. This paper addresses the design of optimal training sequences for efficient estimation of MTOs and multiple channel parameters. A new hybrid Cramér-Rao lower bound (HCRB) for joint estimation of MTOs and channels is derived. Subsequently, by minimizing the derived HCRB as a function of training sequences, three training sequence design guidelines are derived and according to these guidelines, two training sequences are proposed. In order to show …

Transceiver Design For Distributed Stbc Based Af Cooperative Networks In The Presence Of Timing And Frequency Offsets, Ali A. Nasir, Hani Mehrpouyan, Salman Durrani, Steven D. Blostein, Rodney A. Kennedy, Björn Ottersten
Hani Mehrpouyan
In multi-relay cooperative systems, the signal at the destination is affected by impairments such as multiple channel gains, multiple timing offsets (MTOs), and multiple carrier frequency offsets (MCFOs). In this paper we account for all these impairments and propose a new transceiver structure at the relays and a novel receiver design at the destination in distributed space-time block code (DSTBC) based amplify-and-forward (AF) cooperative networks. The Cramér-Rao lower bounds and a least squares (LS) estimator for the multi-parameter estimation problem are derived. In order to significantly reduce the receiver complexity at the destination, a differential evolution (DE) based …

Energy Performance Labeling For Commercial Buildings, Kelli Soll, John Gardner
John Gardner
This white paper provides an overview of commercial building energy performance indices for energy performance in commercial buildings and the extent to which these initiatives have proven effective at reducing energy use. This work focuses on energy performance, as opposed to features of building design associated with improved performance. As such, it will not address design-oriented rating systems such as Leadership in Energy and Environmental Design (LEED) nor will it address building codes.

Policy Pathways, Policy Networks, And Citizen Deliberation: Disseminating The Results Of World Wide Views On Global Warming In The Usa, Jason Delborne, Jen Schneider, Ravtosh Bal, Susan Cozzens, Richard Worthington
Jen Schneider
Leading a coalition spanning 38 countries, the Danish Board of Technology organized World Wide Views on Global Warming (WWViews) on September 26, 2009. WWViews represented a pioneering effort to hold simultaneous citizen deliberations focusing on questions of climate change policy addressed at the UN Climate Change Conference (COP15) in December 2009. Sponsors and organizers envisioned WWViews as a means to affect the COP15 negotations, and the project included numerous strategies to influence policy-making. This paper examines the success of such strategies in the USA through the lens of 'policy pathways,' routes of influence to affect the behavior of policy-makers and …
Phase Noise In Mimo Systems: Bayesian Cramér-Rao Bounds And Soft-Input Estimation, Ali A. Nasir, Hani Mehrpouyan, Robert Schober, Yingbo Hua
Phase Noise In Mimo Systems: Bayesian Cramér-Rao Bounds And Soft-Input Estimation, Ali A. Nasir, Hani Mehrpouyan, Robert Schober, Yingbo Hua
Hani Mehrpouyan
This paper addresses the problem of estimating time varying phase noise caused by imperfect oscillators in multi-input multi-output (MIMO) systems. The estimation problem is parameterized in detail and based on an equivalent signal model its dimensionality is reduced to minimize the overhead associated with phase noise estimation. New exact and closed-form expressions for the Bayesian Cram´er-Rao lower bounds (BCRLBs) and soft-input maximum a posteriori (MAP) estimators for online, i.e., filtering, and offline, i.e., smoothing, estimation of phase noise over the length of a frame are derived. Simulations demonstrate that the proposed MAP estimators’ mean-square error (MSE) performances are …

Planets embedded within dust disks may drive the formation of large scale clumpy dust structures by trapping dust into resonant orbits. Detection and subsequent modeling of the dust structures would help constrain the mass and orbit of the planet and the disk architecture, give clues to the history of the planetary system, and provide a statistical estimate of disk asymmetry for future exoEarth-imaging missions. Here, we present the first search for these resonant structures in the inner regions of planetary systems by analyzing the light curves of hot Jupiter planetary candidates identified by the Kepler mission. We detect only one …

Albertsons Library has successfully leveraged the use mobile devices for helping students learn research skills. Librarians are now going to classrooms and teaching two instruction sessions — 1) finding information and 2) evaluating information. The library sessions provide hands-on, active learning opportunities for student teams, built around the use of iPads to explore library resources. In fall 2012, this included instruction to seventy-four classes in Boise State's "University Foundations 100" course, the first course in our general education program. Ten classes of junior level transfer students received an additional session — 3) advanced searching techniques. The instruction curriculum is purposefully …
Effects Of Gaas(Sb) Cladding Layers On Inas/Alassb Quantum Dots, Paul J. Simmonds
Effects Of Gaas(Sb) Cladding Layers On Inas/Alassb Quantum Dots, Paul J. Simmonds
Paul J. Simmonds
The structural and optical properties of InAs self-assembled quantum dots buried in AlAs0.56Sb0.44 barriers can be controlled using GaAs1−xSbx cladding layers. These cladding layers allow us to manage the amount of Sb immediately underneath and above the InAs quantum dots. The optimal cladding scheme has a GaAs layer beneath the InAs, and a GaAs0.95Sb0.05 layer above. This scheme results in improved dot morphology and significantly increased photoluminescence (PL) intensity. Both power-dependent and time-resolved photoluminescence confirm that the quantum dots have type-II band alignment. Enhanced carrier lifetimes in this quantum dot system …

Variation And Preferences In Modern Hebrew Nonce Verbs, Michal Martinez
Michal Temkin Martinez
This paper reports a production experiment examining variation in Modern Hebrew spirantization. Modern Hebrew spirantization is characterized by the alternation of the stops [p], [b], and [k] with their fricative counterparts [f], [v], and [χ], respectively. Typically, fricatives occur post-vocalically, and stops elsewhere, as in (1). (1) Root Infinitive Uninflected Gloss /p/~[f] /pgʃ/ [lifgoʃ] [pagaʃ] ‘to meet’ /b/~[v] /bgd/ [livgod] [bagad] ‘to betray’ /k/~[χ] /ktb/ [liχtov] [katav] ‘to write’ Due to historical mergers and recent borrowings, there are segments that are acoustically identical to those in (1) but that do not alternate, thus potentially forming exceptions (i.e. post-vocalic stops or …

Regional Influences On Political Identity: Canadian And U.S. Urban Comparisons, Susan Mason
Regional Influences On Political Identity: Canadian And U.S. Urban Comparisons, Susan Mason
Susan G. Mason
Scholars have expanded the academic literature to understand the way culture may influence politics but much less work has considered the influence of region on cities and individuals. The article uses existing data to examine whether liberalism is influenced by the region where individuals and cities are located. The study uses the boolean method and Hierarchical Linear Modeling to control for both individual and city level effects in 8 Canadian cities and 46 U.S. cities. The findings support the supposition that place still matters even in an era when globalization threatens to standardize much of what makes up our communities.

Simultaneous Estimation Of Multi-Relay Mimo Channels, Hani Mehrpouyan, Steven D. Blostein, Björn Ottersten
Simultaneous Estimation Of Multi-Relay Mimo Channels, Hani Mehrpouyan, Steven D. Blostein, Björn Ottersten
Hani Mehrpouyan
This paper addresses training-based channel estimation in distributed amplify-and-forward (AF) multi-input multi-output (MIMO) multi-relay networks. To reduce channel estimation overhead and delay, a training algorithm that allows for simultaneous estimation of the entire MIMO cooperative network’s channel parameters at the destination node is proposed. The exact Cramér-Rao lower bound (CRLB) for the problem is presented in closed-form. Channel estimators that are capable of estimating the overall source-relay-destination channel parameters at the destination are also derived. Numerical results show that while reducing delay, the proposed channel estimators are close to the derived CRLB over a wide range of signal-to-noise ratio values …
New Expression For The Functional Transformation Of The Vector Cramér-Rao Lower Bound, Ali A. Nasir, Hani Mehrpouyan, Rodney A. Kennedy
New Expression For The Functional Transformation Of The Vector Cramér-Rao Lower Bound, Ali A. Nasir, Hani Mehrpouyan, Rodney A. Kennedy
Hani Mehrpouyan
Assume that it is desired to estimate α = f(θ), where f(·) is an r-dimensional function. This paper derives the general expression for the functional transformation of the vector Cramér-Rao lower bound (CRLB). The derived bound is a tight lower bound on the estimation of uncoupled parameters, i.e., parameters that can be estimated separately. Unlike previous results in the literature, this new expression is not dependent on the inverse of the Fisher’s information matrix (FIM) of the untransformed parameters, θ. Thus, it can be applied to scenarios where the FIM for θ is ill-conditioned or singular. …

Phase Noise And Carrier Frequency Offset In Ofdm Systems: Joint Estimation And Hybrid Cramér-Rao Lower Bound, Omar Hazim Salim, Ali A. Nasir, Hani Mehrpouyan, Wei Xiang
Hani Mehrpouyan
In this paper, a new iterative pilot-aided algorithm based on expectation conditional maximization (ECM) for joint estimation of Wiener phase noise (PHN) and carrier frequency offset (CFO) in orthogonal frequency division multiplexing (OFDM) systems is proposed. Next, a new expression for the hybrid Cramér-Rao lower bound (HCRB) for joint estimation of PHN and CFO in OFDM systems is derived. Numerical results show that the proposed estimator outperforms existing algorithms in terms of mean square error while performing close to the derived HCRB at moderate PHN variances. Moreover, the proposed estimator is found to be computationally more efficient than existing algorithms …

Dstbc Based Df Cooperative Networks In The Presence Of Timing And Frequency Offsets, Ali A. Nasir, Hani Mehrpouyan, Salman Durrani, Steven D. Blostein, Rodney A. Kennedy, Björn Ottersten
Hani Mehrpouyan
In decode-and-forward (DF) relaying networks, the received signal at the destination may be affected by multiple impairments such as multiple channel gains, multiple timing offsets (MTOs), and multiple carrier frequency offsets (MCFOs). This paper proposes novel optimal and sub-optimal minimum mean-square error (MMSE) receiver designs at the destination node to detect the signal in the presence of these impairments. Distributed space-time block codes (DSTBCs) are used at the relays to achieve spatial diversity. The proposed sub-optimal receiver uses the estimated values of multiple channel gains, MTOs, and MCFOs, while the optimal receiver assumes perfect knowledge of these impairments at the …

Overloaded Satellite Receiver Using Sic With Hybrid Beamforming And Ml Detection, Zohair Abu-Shaban, Hani Mehrpouyan, Joel Grotz, Björn Ottersten
Hani Mehrpouyan
In this paper, a new receiver structure that is intended to detect the signals from multiple adjacent satellites in the presence of other interfering satellites is proposed. We tackle the worst case interference conditions, i.e., it is assumed that uncoded signals that fully overlap in frequency arrive at a multiple-element small-size parabolic antenna in a spatially correlated noise environment. The proposed successive interference cancellation (SIC) receiver, denoted by SIC Hy/ML, employs hybrid beamforming and disjoint maximum likelihood (ML) detection. Depending on the individual signals spatial position, the proposed SIC Hy/ML scheme takes advantage of two types of beamformers: a …
