Abstract: Title: Distracted by donuts? The cognitive strain of calorie counting may undermine focus and work performance Providing food in the workplace is an increasingly popular practice. But, work on the psychology of scarcity suggests that restrained eaters, when reminded of tempting food, may experience cognitive strain from the demands of managing a calorie budget. Participants prescreened for restricted eating completed cognitive tasks in the presence of either an empty donut box, half-full donut box, or jug of water. Calorie counters performed worse in the presence of an empty donut box, suggesting that simple reminders of food are enough to impose consequential cognitive demands on calorie counters, which may unfairly affect their performance in the workplace.

Abstract: Dissolved organic copper-binding ligands were examined on the U.S. GEOTRACES zonal transect in the Eastern Tropical South Pacific from Peru to Tahiti. All samples were measured using competitive ligand exchange-adsorptive cathodic stripping voltammetry (CLE-ACSV), and a subset were analyzed using multiple competition strengths of the added ligand salicylaldoxime (1, 2.5, 5, 10, and 25 ÂµM). Titration data was processed using newly available multiple analytical window data processing techniques, which unify the multiple window dataset as a whole. Multiple competition strengths of the added ligand enabled the detection of an additional weaker class of copper-binding ligand, compared to the two stronger ligand classes which have been measured previously in the open ocean. The strongest ligand class (L1) ranged in concentration from 1-10 nmol/L and had a conditional stability constant (logK) ranging from approximately 15.0-16.0. The weaker ligand classes (L2, and L3) were present in much higher concentrations even in surface waters, with concentrations ranging from 5-50 nmol/L and conditional stability constants ranging from 8.6-12.5. The elevated ligand concentrations, both in surface and deep waters, lead to extremely low concentrations of Cu2+ throughout the transect, possibly influencing important biogeochemical processes such as inducible iron acquisition by diatoms, and ammonium oxidation in the oxygen minimum zone.

Abstract: Living in Ungoverned Space: Pakistan's Frontier Crimes Regulation Why do substantial swathes of territory remain ungoverned for long periods of time? We explore this question using a unique set of legal institutions in Pakistan that clearly demarcate spaces that are to be left ungoverned. During colonial rule, the British divided Pakistan into two distinct regions. The first was the Raj, where the British built modern political and bureaucratic institutions. In the second region, the British put a small number of political agents in charge of tribal areas and codified pre-colonial institutions in the Frontier Crimes Regulation (FCR). Legal decisions were left to customary law carried out by local tribal councils, or jirgas. Though the area under FCR has steadily decreased, FCR is still in place in the tribal areas of Pakistan today. This makes Pakistan a prime case study in the choice by both colonial and modern governments to leave territory ungoverned in an environment of broadly weak institutions. We use primary legal documents to create a dataset of when and where FCR applied in Pakistan between 1901 and 2012 at the sub-district level. We then exploit the differential impact of the Green Revolution on potential land revenue at the sub-district level empirically model this choice to leave territory ungoverned. We find that sub-districts that we predict would see a disproportionate increase in potential land revenue as a result of the Green Revolution are disproportionately more likely to have FCR removed following the advent of the Green Revolution, relative to before.

Abstract: Purpose: While lesson study has become increasingly popular in the US since the mid 1990s (Stigler and Hiebert, 1999), relatively little research exists surrounding issues sustaining teachersâ€™ lesson study experiences. This study investigates supportive and constraining factors in 80 US mathematics teachers of grades 3 through Algebra 1 (students 8â€“14 years old) with some district support continuing lesson study after their relationship with university faculty ended. Methodology: Teaching is embedded within institutional settings: classrooms, school sites and districts (Cobb, McClain, Lamberg & Dean, 2003), with teachers members of communities formally arranged by the school or district, and informally arranged by themselves (Kramer, 2003). This works aims to understand supports that sustain teachersâ€™ professional learning communities focused on lesson study as situated within institutional settings. For this study, data corpus includes survey results from 80 teachers of mathematics asking about lesson study intentions and support for intentions, and clinical interview data from 30 teacher and district participants. Data was collected 6-12 months after the conclusion of former grant. Data were analyzed using grounded theory methods (Corbin & Strauss, 1990) and informed by Woolcockâ€™s (1998) conditions of sustainability: integration, linkage, organizational integrity and synergy. Results: I first characterize which aspects of lesson study have continued as reported by participants. I then report on factors that appear to support continuing to engage in lesson study. Implications: Practically, we consider how to better support teachers in professional development in engaging in lesson study after grants ends to address issues of sustainability. Theoretically, we consider the need to reconceptualize sustainability for lesson study. Originality/Value: This research examines practices and communities that get reorganized when relationships among teachers shift. Theoretically, this study encourages thinking about how to define sustainability with lesson study productively and whether sustainability a la Woolcockâ€™s (1998) sustainability model is appropriate.

Abstract: Title: The Distinct Observable Signatures of Multi-Pathway Conformational Transitions in Biomolecules Abstract: Complex biomolecules and biomolecular assemblies are typically characterized by equally complex conformational transitions. A prime example of this complexity is a transition that occurs via competing pathways, where the competition between pathways is often essential for biological function. However, how can one recognize the presence of competing pathways and distinguish it from other mechanisms, based on the data from single-molecule pulling experiments? Here, we identify a set of distinct signatures in the experimentally measurable force-dependent rates and distribution of transition forces that can be used as diagnostic tools to distinguish the multi-pathway mechanism among several candidate mechanisms. The developed theory enables one to identify the underlying multi-pathway kinetic scheme and results in analytical expressions that can be readily fit to experimental data to extract the barriers and rates that define each of the competing pathways.

Abstract: Nonnegative matrix factorization (NMF), which aims to approximate a data matrix with two nonnegative low rank matrices, is a popular dimensionality reduction and clustering technique. Due to the non-convex formulation and the nonnegativity constraints on the two low rank matrices (with rank r > 0), it is often difficult to solve NMF efficiently and accurately. Recently, the alternating direction method of multiplier (ADMM) was shown to be more accurate and efficient than traditional approaches such as the multiplicative update rule (MUR) or alternating least square (ALS). Nevertheless, the computation of ADMM is proportional to the cube of the rank of because of the underlying matrix inverse problem and thus may be inefficient when r is relatively large. In this paper, we propose a rank-one ADMM to address this problem. In each step, we search for a rank-one solution of NMF based upon ADMM and utilize greedy search to obtain the low rank matrices. In this way, rank-one ADMM avoids the matrix inverse problem and the computation is only linearly proportional to r. Thorough empirical studies demonstrate that rank-one ADMM is more efficient and accurate than baseline approaches.

Abstract: This paper tries to explain the change of national monetary policies choices in authoritarian regimes. It argues that the monetary policy outcomes in authoritarian regimes could be explained by the strategic interactions between political factions. Since exchange rate policy can generate a redistributional effect, the authoritarian leader has incentives to use the policy to fortify his faction and weaken his challengersâ€™ economic coalition bases. The monetary policy outcomes will depend on the degree that the challengers can block the policy. This paper uses RMB appreciation during 2003 to 2010 as a case to illustrate the factional model. This paper will use Time Series Cross-Section analysis and game theory to analyze the factional data and economic data during 2003-2013. The results show that the economic redistribution effect of RMB appreciation would benefit the political leaderâ€™s faction and weaken his challengerâ€™s faction in provinces, and the level of the RMB appreciation would depend on the factionsâ€™ strategic interactions in the central level.

Abstract: The medicinal leech is a segmented annelid with 21 stereotyped midbody ganglia each responsible for sensing, communicating with the other ganglia, and producing behavior relevant to the segment it innervates. These ganglia all contain the same complement of approximately 400 neurons. Each neuron possesses a large cell body arranged on the exterior of the ganglion, and a central region of neuropil where the synaptic circuitry is established. To begin unraveling this circuitry, we are applying a connectomic approach relying on serial blockface electron microscopy (SBEM). Here we present data collected from an entire ganglion collected from a smaller but still behaviorally-mature juvenile leech. Within this volume of data, we have segmented several motor neurons and identified the connections between them. With this dataset, we show that we can identify known synapses (identified via previous experiments using intracellular electrophysiology) and that we can begin answering questions about the number and spatial distribution of these synapses in the neuropil.

Abstract: Detecting and tracking social marine mammals, including bottlenose dolphins, can help to explain their social dynamics, predict their behavior, and measure the impact of human interference. Multi-camera setups provide an opportunity to record the behavior of captive dolphins and create a massive dataset from which long term statistics can be extracted, but the use of human experts to track dolphin positions over time demands a high time and financial investment cost. In this paper, we examine automated methods to analyze large video corpora. We use background subtraction to detect dolphins over time in the video data and to visualize the paths by which dolphins regularly traverse their environment. We demonstrate the use of these background subtraction methods as a way to initialize a preexisting real-time compressive tracking algorithm, which previously required human interaction. Detecting when dolphins transfer between pools both supplements 3D tracking efforts, helping identify moments when dolphins move between cameras, and augments human performance, providing a way for researchers to manually annotate dolphin pool positions 14 times as fast.

Abstract: Parking Lot Park is a performance event that maps the various geographies (geologic, political, social, and sexual) which intersect within the space of San Clemente Canyon, in San Diego, California. Currently known as Marian Bear Memorial Open Space Park, the land has undergone many transformations: a harvesting point for the Kumeyaay Indians and later grazing territory for Mexican cattle ranchers, the presently U.S.-owned canyon was protected from highway expansions in the 1970s by itâ€™s namesake, Marian Bear. Since this period, rampant urban development has hemmed the canyon, creating an island of green in an otherwise suburban landscape. In recent years, the park has become a popular cruising spot for homosexual encounters, sparking a backlash of plainclothes arrests and police surveillance. Part site-specific installation, part aural and visual ethnography, and part ficto- criticism writing, Parking Lot Park unfolds November 2014 as a sound promenade and drive-in theater within the canyon itself. Staged over multiple evenings for audiences of 60, participants will traverse the canyon to discover 6 sound art installations. Each sound promenade station gives voice to an individual layer of the human geography of Marian Bear Park. Projected through a set of custom built speakers, stories are told through recorded vocal narration, interwoven and counterbalanced with processed and manipulated field recorded sounds from the canyon. Cast in concrete, buried under soil, hanging from oak trees, or projected from institutional horns, the sound promenade speakers respond both aurally and visually to the park trails and itâ€™s subject matter. The evening will conclude with a drive-in theater, where participants will return to their cars in the parking lot and watch a 15 minute film about the origin myth erotics of the geologic birth of the canyon, which will include a sound composition designed for the insulated intimacy of a car cab (and broadcast via low-powered FM transmitter). By drawing out individual threads of material and social engagement in San Clemente Canyon, the project proposes that landscape is a constantly shifting expression of emergent, dominant, and residual patterns. Parking Lot Park presents geologic time as both erotic and contingent as the dynamic between lovers, and conversely, that human environmental influence is as much of a layer as sedimentary rock. At the Hearing Landscape Critically conference, we will deliver a hybrid presentation focusing on three of the seven works. We will present the story of Wyatt, a veterinarian who has been using the space for public sex since the late 1980â€™s; Yoli, an indigenous Kumeyaay captain who used the canyon as a harvesting site in 10,000 BCE; and finally an excerpt from the drive-in theater film dealing with the canyonâ€™s geologic inception 5 and a half million years ago. We will present an excerpt from each piece accompanied by a discussion of the research behind the stories, their accompanying field recordings, and design of their physical installation. Our presentation would ideally be 30 minutes long plus questions. We will transport a set of concrete speakers from San Diego, to give a more vivid image of the physical manifestation of the project.

Abstract: Emerging applications such as wearable electronics and the internet of things necessitate wireless transmission of large datasets and generate the need for efficient energy consumption. Exactly digitizing and transmitting this data is energy costly. Most decision-making applications involving this data are statistical. It is well known that for any statistical decision-making problem the posterior distribution is a sufficient statistic. Thus, for the aforementioned applications, it is desirable to locally calculate a posterior distribution and transmit only that information. However, calculating the posterior, especially in large dimensions, is traditionally hard. We here show that for a large class of problems we can exactly compute the posterior distribution using distributed optimization algorithms that are robust to randomness. In these classes of problems, we show that even in very large dimensions, we can perform exact Bayesian inference by simply drawing independent samples and solving distributed convex optimization problems. We accomplish this by formulating Bayesian inference as a problem in finding a nonlinear map that exactly transforms samples from one distribution to samples from the posterior. We show that this problem can be cast as a KL-divergence minimization and moreover that this problem is convex. We also demonstrate that for certain classes of problems this convex framework can be exactly solved with systems of low-energy analog circuits in a parallel, distributed manner. Specifically, we consider applications such as imaging and spectroscopy where the latent signal can be modeled as having a sparse â€œLaplacianâ€ prior with respect to an appropriate basis, and our measurement model is linear and Gaussian. We show that this distributed algorithm converges in an exponential manner to the true optimization solution. We have implemented this algorithm in the Parallella board, the worldâ€™s smallest and most energy efficient supercomputing platform in a proof-of concept to enable emerging applications like wearable electronics. We measure performance of risk minimization within the context of decision-making and show that our algorithm outperforms point estimates methods traditionally used in machine learning applications. To our knowledge, this is the first distributed algorithm that can perform Bayesian Inference in a scalable manner. Our method of calculating the posterior fundamentally differs from methods such as Markov Chain Monte Carlo, and it exhibits better performance-complexity tradeoffs.

Abstract: Interaction at velocity: Representing childrenâ€™s locomotion in the age of mobile video Work on embodied interaction (Streeck, Goodwin and LeBaron 2011) has largely concentrated on social actors who are relatively static in space, investigating phenomena such as gesture, posture, eye gaze, or the manipulation of objects. But not all social actors are so likely to stay in one place; and the availability of increasingly portable video and audio recording equipment means that even the most itinerant bodies might be available for study. This paper explores methodologies for the study of childrenâ€™s quotidian interaction, which often involves rapid changes of location, and can take place at high speeds and across vaster spaces than is typical for adults. The data come from an extended ethnographic study of bilingual (Zapotec/Spanish) children from JuchitÃ¡n, Oaxaca, Mexico, which examines the link between spatial practice and spatial cognition. Drawing on extensive video recordings of these childrenâ€™s interaction with each other and the environment, I discuss the methodological problems posed by this corpus of â€œinteraction at velocity.â€ I then discuss several techniques for representing both the spatial and temporal elements of these data, including spatialized transcriptions and layered mapping. These techniques help reveal the role of locomotion in structuring childrenâ€™s interaction, and allow for the visualization of the dynamic coordination of bodies in the material world. Advances in video recording technology allow us to apprehend new embodied phenomena, but also require new techniques for visualization and analysis of these ever more detailed data.

Abstract: Title of paper: â€œWhen the Just Govern, the People rejoiceâ€: Pentecostal Politics and Transformation in Brazil This paper explores the involvement of Pentecostal believers with politics in recent years in Brazil and investigates the role of the core Pentecostal category of transformation embedded in this political enterprise. I argue that the idea of transformation â€“ conceived in Brazilian Pentecostalism as a transformation of the self and of society â€“ is constitutive of a political theology triggered by a Pentecostal model of politics. In this model, religion and politics are no longer conceived in the traditional liberal Western dichotomies in which a hiatus exists between religion and politics, civil law and religious law, the church and the state, and so forth. Politics, for these Brazilian Pentecostal believers, is conceived as a landscape that these believers are called upon to act on and transform, as part of their life as (good) Christians. After a period of pre-dissertation fieldwork, I note that these Brazilian Pentecostals work to transform themselves and the religious movement they integrate politically â€“ through a process I denominate Political Evangelization â€“ which entails the transformation of Pentecostal citizenship into a genuinely accepted Christian practice in the church/private settings. In the same fashion, these believers also work to transform society and its moral demises brought about mainly by addiction, corruption, and homosexuality through political participation and involvement in the Brazilian National Congress.

Abstract: Conference accepts Extended Abstracts. In the following, part of the introduction of one of the paper I'll present is reported: " It is a recurring circumstance, in aircraft design, to re-size layout after a preliminary assessment of a solution outcome of a conceptual design stage. For cantilevered classical configurations, after years of practice and experience this problem has been mitigated and does not represent an insurmountable issue. For Joined Wings there is no similar industrial experience. Thus, attempts to conceptually design such a configuration using handbook or very low fidelity tools have always resulted in non-competitive layouts. However, the situation is actually even more challenging. Due to the geometrical layout of a typical Joined Wing, there is an unavoidable coupling of the different disciplines. This paper presents the study of the aeroelastic phenomena when (structural) nonlinearities are taken into consideration. In detail, it focuses on the impact of control surface freeplay on futter which has never been studied before for Joined Wings. Differently than traditional configurations, for the PrandtlPlane Joined Wings there are multiple mobile surfaces located on two wings. Thus, the response of the system will be the result of a complicated interaction of each control surface freeplay. A physical understanding of the dynamic aeroelastic response due to these effects on a realistic configuration is then crucial for an effective design.

Abstract: Moraic geminates in Malayalam: evidence from minimal word e ects and loanword adaptation We present new evidence to show that, contrary to previous stress-based analyses (e.g. Mohanan (1989)), Malay- alam geminates must be moraic in at least some contexts. We present and discuss evidence for the moraicity of geminates in both native words and in loanword adaptations, and we provide criteria for determining which of two strategies are used in the adaptation of CVC loanwords from English. The minimal word in Malayalam is bimoraic (Mohanan (1989)). Vowel and consonant length is phonemic, and long vowels are bimoraic, though CVC syllables are monomoraic (Broselow et al. (1997)). Both schwas and geminates have been claimed to be nonmoraic (Cyran (2001); Mohanan (1989)). However, evidence from native Malayalam words shows that geminates must be moraic; CVC:@ structures are licit (1), while *CVC@ structures are not (2): (1) pal:@ CVC:@ tooth' (2) * pal@ CVC@ The contrast between (1) and (2) can only be explained if we assume that the geminate in (1) is moraic, satisfying the minimal word requirement. Further evidence that geminates are moraic comes from loanword adaptation. Malayalam speakers adapt CVC words from English using two di erent strategies: in (3), the vowel is lengthened, while in (4), the vowel stays short and the coda consonant is geminated, which results in a word with the structure CVC:@. In both cases, a schwa is epenthesized in order to resolve an illicit coda, but crucially, in order to account for examples like (4), geminates must be moraic, as /@/ does not contribute a mora and the minimal word must be bimoraic. (3) a. /phA:s/ (English input) b. pa:s@ (vowel-lengthened loanword) pass' (4) a. /b2s/ (English input) b. bas:@ (geminated loanword) bus' Choice of strategy depends on perceived vowel length. English tense vowels are adapted as long Malayalam vowels, as in (5), while lax vowels are borrowed as short vowels with geminate coda consonants, as in (6). The one exception is lax /Ã¦/ (7), which we assume is due to its greater phonetic length (van Santen (1992)). (5) a. /seIl/ (input) b. * sel:@ (geminate) c. se:l@ (long vowel) sale' (6) a. /k2p/ (input) b. kap:@ (geminate) c. * ka:p@ (long vowel) cup' (7) a. /mÃ¦p/ (input) b. * map:@ (geminate) c. ma:p@ (long vowel) map' English CVC loanwords can undergo gemination in order to satisfy minimal word constraints in Malayalam, and this process is sensitive to both phonemic length (= tense vowels) and phonetic length (= //) in English. The gemination strategy is unexpected given previous analyses claiming that Malayalam geminates are nonmoraic. Our analysis, which treats Malayalam geminates as moraic, correctly accounts for the gemination strategy for loanword adaptation, explains the presence of native words with the structure CVC:@, and preserves the inherent moraicity of geminates, as posited in Moraic Theory (Hayes (1989)). In the talk, we will also discuss the implications of this analysis for longer loanwords and the moraic status of geminates in other positions.

Abstract: Bribing the Self (by Uri Gneezy, Silvia Saccardo, Marta Serra-Garcia, Roel van Veldhuizen). Abstract: We examine whether individuals are more likely to behave unethically when they can engage in self-deception, convincing themselves that their behavior is ethical. In two experiments, decision-makers evaluate two options and are asked to recommend one based on quality. In both cases they are provided with a monetary incentive to recommend one of the options. When informed about the incentive before learning about the options, individuals' choices are systematically biased in the direction of the incentive. However, when this information comes after they learn about the quality of the options, this bias is reduced and choices are more honest.

Abstract: Does Test-Enhanced Learning Transfer for Triple Associates? Steven C. Pan and Timothy C. Rickard, University of California, San Diego Transfer of test-enhanced learning in the case of tripled associate word stimuli was assessed in four experiments. In contrast with the robust transfer that has been demonstrated for paired associates, we observed minimal transfer from trained to untrained items for tripled associates. That result held when one or two items from each triplet was tested on during training, as well as when one item from each triplet was repeatedly tested on during training. However, testing on all possible items for each triplet resulted in an amplification of test-enhanced learning. Thus, although test-enhanced learning appears to transfer minimally for triplets, and likely other multielement stimuli, where feasible, testing on many or all possible stimulus-response combinations can be highly productive for learning.
