description: Assets are an important means of coping with adverse events in developing countries but the role of gendered ownership is not yet fully understood. This paper investigates changes in assets owned by the household head,his spouse,or jointly by both of them in response to shocks in rural agricultural households in Bangladesh with the help of detailed household survey panel data. Land is owned mostly by men,who are wealthier than their spouses with respect to almost all types of assets,but relative ownership varies by type of asset. Controlling for unobserved heterogeneity across households and looking at changes within,rather than between,households,we find that weather shocks such as cyclones adversely affect the asset holdings of household heads in general,while predicted external events lead to assets of both spouses being drawn down. The results,furthermore,suggest that jointly owned assets are not sold in response to shocks,either due to these assets being actively protected or due to the difficulty of agreeing on this coping strategy,and that women’s asset holdings and associated coping strategies are shaped by their lower involvement in agriculture.
Preferences in Learning "Hiragana": A Comparative Study Between Mobile Apps and Paper Worksheets
Creators: name: Nakada, Michiko
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: In 2020, technology is generally accepted, and we can see many people using their digital devices such as smartphones everywhere. It is easy to see how dependent we are on technology, anytime and anywhere. Mobile apps are one of the time-effective tools for our daily lives. College students in the United States are always busy with their classes and assignments, and for them, apps are not only for having fun but are also convenient, reliable, and essential supporting tools for their academic and daily lives.
 This paper examines the students’ preferences in learning the Japanese writing system “Hiragana” with mobile apps and paper worksheets. The study had 14 participants who joined a 4-day-a-week class. The participants were asked to use both the app “Ganbatte kana” and copies of the worksheet “Purinto Kizzu” to practice Hiragana in and out of class. After all four classes over 1 week, the participants answered a questionnaire about the class and what they thought of using the paper and the app to study Hiragana based on their experience.
The results of this study showed that most students preferred the paper to the app. While most of them use their smartphones every day, they have an attachment to paper. Some of them preferred physical experiences more than digital experiences for writing. However, most of them appreciate the app’s multifunctionality and convenience, and half of them want to use both apps and paper for their future learning. If we can use both in each strong area effectively, we can expect new technology and traditional materials to become more satisfying and useful learning tools.

description: Background and purpose — Total hip arthroplasty (THA) is increasing as treatment of displaced femoral neck fractures. Several studies compare hemiarthroplasty (HA) with THA, but results vary and few studies report on medical complications. We examined the outcome of THA and HA with a focus on medical complications, hip complications, and death. Patients and methods — Data from the Swedish Hip Arthroplasty Register on 30,953 acute hip fracture patients treated with cemented THA or HA in 2005–2011 were cross-matched with Statistics Sweden for socioeconomic data and with the National Patient Register for diagnostic codes representing medical complications within 180 days or hip complications within the study period. Propensity score matching was used to create comparable groups based on age, sex, income, level of education, marital status, Elixhauser index, and year of surgery. Logistic regression models were created for each outcome. Results — 81% were treated with HA, 73% and 71% were female (HA and THA respectively). Matching resulted in 2 groups of 5,815 patients each. THA was associated with fewer medical complications (OR = 0.83; 95% CI 0.76–0.91) and lower 1-year mortality (OR = 0.42; CI 0.38–0.48), but more hip complications (OR = 1.31; CI 1.20–1.43). Interpretation — THA as treatment of hip fracture was associated with more hip-related complications than HA. The results on mortality and medical complications are, rather, influenced by residual confounding than by the implant design per se. An expansive use of THAs for hip fracture treatment, at the expense of HAs, is not recommended based on our findings if hip complications are to be avoided.

description: My research aims to highlight the way in which Black political mobilization in the Southeastern United States specifically is linked to the movement for decolonization throughout Africa and the Caribbean in this time period. This project will include an examination of the thoughts and writings of many of the aforementioned key figures of the Pan African movement on the question of race and coloniality of Black people in the United States. I will organize this examination around the question of Black labor at this time period and the way in which it was (re) organized leading up to the Second World War leading to the “success” of development projects throughout the rural Southeast, mainly the Tennessee Valley Authority. This will lead to an analysis of the way in which Black southern communities specifically understood their positionality in connection to that of colonized subjects throughout the Black Atlantic.
Resonance estimates of O(p^6) low-energy constants and QCD short-distance constraints

description: Starting from the study of the low-energy and high-energy behaviours of the QCD three-point functions , and , several O(p^6) low-energy constants of the chiral Lagrangian are evaluated within the framework of the lowest meson dominance (LMD) approximation to the large-N_C limit of QCD. In certain cases, values that differ substantially from estimates based on a resonance Lagrangian are obtained. It is pointed out that the differences arise through the fact that QCD short-distance constraints are in general not correctly taken into account in the approaches using resonance Lagrangians. We discuss the implications of our results for the O(p^6) counterterm contributions to the vector form factor of the pion and to the decay π-> e ν_e γ, and for the pion-photon-photon transition form factor.

description: In the last two decades, approximately 200 quasars have been discovered at $z>6$, hosting active super-massive black holes with masses $M_{\bullet} \gtrsim 10^9 M_{\odot}$. While these sources reflect only the tip of the iceberg of the black hole mass distribution, their detection challenges standard growth models. The most massive $z>6$ black hole that was inferred thus far (J0100+2802, $M_{\bullet} \approx 1.2\times 10^{10} M_{\odot}$) was recently claimed to be lensed, with a magnification factor $μ=450$. Here, we perform a consistency check of this claim, finding that the detection of such source requires a bright-end slope $β\geq 3.7$ for the intrinsic quasar luminosity function, $Φ(L) \propto L^{-β}$. Commonly used values of $β\sim 2.8$ are rejected at $>3σ$. If the claim is confirmed, it is very unlikely that all the remaining $51$ sources in the SDSS sample are not magnified. Furthermore, it suffices that $\gtrsim 25\%$ of the remaining sources are lensed for the intrinsic luminosity function to differ significantly (i.e., $>3σ$) from the observed one. The presence of additional extremely magnified sources in the sample would lower the requirement to $\sim 4\%$. Our results urge the community to perform more extended multi-wavelength searches targeting $z>6$ lensed quasars, also among known samples. This effort could vitally contribute to solving the open problem of the growth of the brightest $z\sim 7$ quasars.

Urbanlization and Internet Literature: Zhang Jiajia and His Healing Story

description: In 2013, Zhang Jiajia 张嘉佳’s book I Belonged to You (从你的全世界路过； thereafter Belonged) became a huge hit and a miracle of publication. In 2013 after half a year in circulation, the paper print sold more than 2,000,000 copies and was soon adapted to two movies. In 2014, both the kindle and paper edition of Belonged won No.1 for the best books list on Amazon China. Zhang Jiajia’s incredible success is a miracle, and it can only happen with the easy access of Internet. In addition to that, the lifestyle Belonged depicts is what post-80s and post-90s generations in China are experiencing now. My thesis studies how the Internet and Sina Weibo platform make the popularity of Belonged possible and why post-80s and post-90s readers from Sina Weibo like this kind of story. By investigating the reasons behind this book’s popularity, I argue that Internet literature and literary works in a similar genre to Belonged fulfill the emotional needs of post-80s and post-90s generations, which the literature works written by writers who receive government stipends cannot meet.
Is Everyone Hanging Out Without Me? (And Other Dramaturgical Concerns): Re-Centering Dramaturgy and Comedy as Feminist Tools for Social Change
Creators: name: Schmidt, Shaila
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Titled as a play on Mindy Kaling’s 2011 book, Is Everyone Hanging Out Without Me? (And Other Concerns), this thesis highlights the obstacles women, the genre of comedy, and dramaturgs face in order to be taken seriously in the arts. Using the work of Mindy Kaling, I explore how she uses comedy as a means of defying the expectations put upon her as an Indian American woman in order to provide context for the ways in which the marginal statuses of women of color and comedy overlap.
In an effort to demonstrate the ways in which comedy can be utilized as a tool for social change and the ways in which the work of a dramaturg can support that, this thesis documents the planning and execution of three events that accompany this written document: a production of Mindy Kaling and Brenda Withers’ 2002 play, Matt & Ben; a screening of the 1997 Oscar-winning film, Good Will Hunting; and a Q+A conversation with Broadway’s most-produced female playwright, Theresa Rebeck.
My work is shaped by various theoretical frameworks, including intersectional feminism, symbolic annihilation, charged humor, and gender performance theories, seeking to establish that my dramaturgical, comedic, and feminist sensibilities are all driven by the same empathetic impulse that sits at the very core of my artistry and arguing that despite a vast history of marginality, dramaturgs, comics, and women can be powerful agents of change.
Triple and quartic interactions of Higgs bosons in the two-Higgs-doublet model with CP violation

description: We consider the two-Higgs-doublet model with explicit CP-violation, where the effective Higgs potential is not CP-invariant at the tree-level. Three neutral Higgs bosons of the model are the mixtures of CP-even and CP-odd bosons which exist in the CP-conserving limit of the theory. The mass spectrum and tree-level couplings of the neutral Higgs bosons to gauge bosons and fermions are significantly dependent on the parameters of the Higgs boson mixing matrix. We calculate the Higgs-gauge boson, Higgs-fermion, triple and quartic Higgs self-interactions in the MSSM with explicit CP-violation in the Higgs sector and CP-violating Yukawa interactions of the third generation scalar quarks. In some regions of the MSSM parameter space substantial changes of the self-interaction vertices take place, leading to significant suppression or enhancement of the multiple Higgs boson production cross sections.

Examining the Tools Used to Infer Models of Lexical Activation: Eye-tracking, Mouse-tracking, and Reaction Time
Creators: name: Levy, Joshua
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Most models of auditory word recognition describe the activation of lexical items in a continuous and graded manner. Much evidence in favor of these models comes from the visual-world paradigm, using either eye fixations or computer cursor trajectories as dependent measures. In particular, Spivey, Grosjean and Knoblich (2005) relied on their observation of unimodality in the distribution of cursor trajectories to argue in favor of a single cognitive process consistent with a continuous model of lexical activation. The present study addresses two questions: (1) whether the logic of inferring the number of cognitive processes from distributional analyses can be extended to a different dependent variable – reaction times, and (2) how robust the distribution of cursor trajectories is to changes in cursor speed (mouse gain). In Experiment 1, eye movements and reaction times were recorded in a visual-world paradigm and reaction times were modeled using ex-Gaussian curve-fitting. Participants responded slower to trials with a phonological competitor presented alongside the target than to trials with a control image presented alongside the target. Crucially, this difference was manifested as a shifting of the distribution rather than as a skewing of the distribution and lends additional support for a continuous model of lexical activation. Experiment 2 measured eye and mouse movements concurrently in a similar visual-world task to investigate the relationship between these two dependent measures at the level of the individual trial. In addition, Experiment 2 manipulated the speed of the cursor (mouse gain) between subjects. The low mouse gain served to reduce the effect of phonological competition. Moreover, the shape of the distribution of cursor trajectories across phonological competitor and control conditions was indistinct with low mouse gain, while the shape of the distributions across the two conditions differed with high mouse gain. This effect of mouse gain shows that the distribution of cursor trajectories is not robust to changes in mouse gain. Moreover, it raises questions about the strength of the linking hypothesis necessary to interpret the distribution of cursor trajectories.
Designing Surveys on Youth Immigration Reform: Lessons from the 2016 CCES Anomaly
Creators: name: Calkins, Saige
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Even with clear advantages to using internet based survey research, there are still some uncertainties to which survey methods are most conducive to an online platform. Most survey method literature, whether focusing on online, telephone, or in-person formats, tend to observe little to no differences between using various survey modes and survey results. Despite this, there is little research focused on the interaction effect between survey formatting, in terms of design and framing, and public opinion on social issues, specifically child immigration policies - a recent topic of popular debate. This paper examines an anomalous result found within the 2016 Cooperative Congressional Election Study (CCES) public opinion immigration question focusing on a DACA-related policy, where support was evenly split on the typically highly favored policy. To decipher the unprecedented result, an experimental survey design was conducted via Qualtrics by comparing various survey formats (single-style, forced choice, Likert scale) and inclusionary policy details to the original CCES “select all that apply” matrix style. By comparing the experimental polls, the results indicated that the “select all that apply” matrix again produced anomalous results, while the various other methods produced a breakdown similar to typical DACA-related polling data. These findings have necessary implications for future survey designs and those examining public opinion on child immigration policies.

QCD corrections to decay-lepton polar and azimuthal angular distributions in e+e- -> t tbar in the soft-gluon approximation

description: QCD corrections to order alpha_s in the soft-gluon approximation to angular distributions of decay charged leptons in the process e+e- -> t tbar followed by semileptonic decay of t or tbar, are obtained in the e+e- centre-of-mass frame. As compared to distributions in the top rest frame, these have the advantage that they would allow direct comparison with experiment without the need to reconstruct the top rest frame. The results also do not depend on the choice of a spin quantization axis for t or tbar. Analytic expression for the triple distribution in the polar angle of t and polar and azimuthal angles of the lepton is obtained. Analytic expression is also derived for the distribution in the charged-lepton polar angle. Numerical values are discussed for total c.m. energies of 400 GeV, 800 GeV and 1500 GeV.

LITERARY PORTRAYALS OF RELIGIOUS AWAKENING THROUGH SUFFERING AND LOSS - BUDDHIST, DAOIST, AND CHRISTIAN PERSPECTIVES
Creators: name: Canning, Robert
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: The focus of this study is on portrayals of religious awakening in four short works of literature: a Chinese play, two Chinese short stories, and an American short story. In all of these works, the protagonists attain religious awakening, but only do so because they experience suffering and loss.
The experience of suffering and loss in these works helps to bring about the protagonists’ willingness to leave the worldly life. This is because the experience of suffering and loss clears the minds of the protagonists and helps them to realize the bitter nature of worldly existence.
In addition, these works portray worldly concepts from the perspective of a mystical, transcendent order of reality. Things that appear normal from a worldly perspective are abnormal from the mystical perspective, and vice versa. Thus, the wise may appear foolish, the sane crazy, and the successful materially destitute, to name a few examples.
In these works, religious heroism (a characteristic of the protagonists) also appears unheroic because of this distorted perspective. Religious heroism may appear cowardly, for example, and religious success may appear to be a failure or a tragedy.
These literary portrayals of religious awakening through suffering and loss may thus help to shed light on religious concepts common to Buddhism, Taoism and Christianity, and also on the differences between the worldly and mystical perspectives.
Impact of Predators on Hemlock Woolly Adelgid (Hemiptera: Adelgidae) in the Eastern and Western United States
Creators: name: Crandall, Ryan
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Hemlock woolly adelgid, Adelges tsugae, native to Asia and the Pacific Northwest of North America (Pacific Northwest), has devastated eastern hemlock (Tsuga canadensis) in a major portion of its range in the eastern U.S. After many years and much effort directed towards rearing and releasing biological control agents to manage HWA, one of these agents, Laricobius nigrinus, native to the Pacific Northwest, is now well-established in sites from the southern to the mid-Atlantic states of the eastern U.S. However, there have yet to be studies of its efficacy in lowering A. tsugae densities, and there has been no noticeable drop in A. tsugae densities. Population models for A. tsugae have suggested that even upwards of 90% predation on eggs laid by the overwintering generation will have minimal effect in reducing the population densities of A. tsugae, if A. tsugae are at high density, due to compensatory density-dependent survival in the progrediens generation. Additionally, no studies showing insect predators are indeed what regulate A. tsugae in its native range exist. We established predator exclusion experiments, and recorded A. tsugae densities, mortality factors, and fecundity for multiple generations in both the native and invaded ranges. In the invaded range, we studied A. tsugae populations in sites with well-established populations of L. nigrinus to test its efficacy in reducing A. tsugae and tested model predictions of minimal difference in A. tsugae densities between treatments with and without predators. In the Pacific Northwest we tested the effect of insect predators and tree species, western (Tsuga heterophylla) and eastern hemlock, on populations of A. tsugae. In the invaded range we found that L. nigrinus predation was significantly higher in unbagged branches, however, model predictions were validated, and there was no effect of predation by treatment on the A. tsugae summer generation. In our plots in the Pacific Northwest we found that tree effects were not significant, but that summer-active predators were significantly lowering levels A. tsugae densities on unbagged branches. Our study demonstrates the importance of summer-active predators in reducing A. tsugae and suggest that summer- and winter-active predators are needed to suppress A. tsugae to innocuous densities.

description: Ethiopia has a large livestock population that performs multiple functions and contributes to food security both directly and indirectly. However, the contribution of the sector to the economy is much less than its potential due to various reasons, one of the important reason lies in the problems associated with domestic and international marketing of livestock. Current knowledge on livestock market structure, performance and prices is poor and inadequate for designing policies and institutions to overcome perceived problems in the marketing system to address its links with food security. Knowledge on how marketing routes and systems contribute to spread of diseases and the implications of these for national and international trade in livestock is also highly inadequate to design any policy or institutional innovation to improve marketing for the benefit of the poor. Further, exploitation of the export market will require an understanding of the market potential in the importing countries including growth in demand, SPS and other quality requirements, rules and regulations governing the market, Ethiopia’s competitiveness in the market in relation to alternative suppliers and ability of the domestic market to respond to the export market opportunities

One possibility is that telomeres, conserved DNA sequences at chromosome ends that often shorten with age and stress exposures, may reflect differences in vital processes or influence fitness. Telomere length often predicts longevity, but longevity is only one component of fitness and little is known about how lifetime reproductive success is related to telomere dynamics in wild populations. We examined the relationships between telomere length beginning in early life, telomere loss into adulthood and lifetime reproductive success in free-living house sparrows (Passer domesticus). We found that females, but not males, with longer telomeres during early life had higher lifetime reproductive success, due to associations with longevity and not reproduction per year or attempt. Telomeres decreased with age in both sexes, but telomere loss was not associated with lifetime reproductive success. In this species, telomeres may reflect differences in quality or condition rather than the pace of life, but only in females. Sexually discordant selection on telomeres is expected to influence the stability and maintenance of within population variation in telomere dynamics and suggests that any role telomeres play in mediating life-history trade-offs may be sex specific.

description: A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50% over a twelve-year planning period, average per ha nutrient balances indicate significant nutrient mining and associated soil losses of about 31 tons per ha. With the adoption of an integrated package of new technologies (involving new high yielding crop varieties, agroforestry, animal manure and inorganic fertilizers use, construction of a communal drain to reduce water logging and some limited land user rights), results show the possibility of an average twoand- a-half-fold increase in cash incomes and a 28% decline in aggregate erosion levels over a twelve year period with a population growth rate of 2.3%. Moreover, a minimum daily calorie intake of 2000 per adult equivalent could be met from on-farm production, and per ha nutrient balances, while still negative for nitrogen and potassium, could be reduced by 36 and 6 % respectively, with phosphorous balances being reversed to positive values. However, these gains might be eroded by the need to meet increased nutritional demands arising both from increasing consumption levels and a more rapid population growth of over 2.8%. From a policy perspective, this reduction in nutrient losses in the face of higher reliance on the watershed for subsistence food requirements, would imply an increasing need for a more secure land tenure policy than currently prevailing, provision of credit to facilitate uptake of the new technology package and a shift from the current livestock management strategy that emphasizes use of livestock as a store of wealth to the one that encourages livestock keeping as a commercial activity. It would also imply a shift from a general approach to land management to a relatively more site-specific approach that recognizes the need for spatial and inter-temporal variability in input use based on land quality that would encompass an efficient nutrient management strategy.
code for DEM simplification (The peer-reviewed publication on IJGIS: An integrated method for DEM simplification with terrain structural features and smooth morphology preserved)

description: As a key focus of cartography and terrain analysis, the simplification of a digital elevation model (DEM) is used to preserve the pattern features of the terrain surface while suppressing its details over multiple scales. Statistical filtering and structural analysis methods are commonly used for this process. The structural analysis method performs well in identifying terrain structural edges, while it tends to discard the smooth morphology of a terrain surface. In addition, the filter that aims to reduce noise on a surface may over-smooth the terrain structural edges. Therefore, to preserve both the terrain structural edges and smooth morphology, we propose to combine the techniques of statistical filtering and structural analysis. Specifically, all the critical elevation points and structural edges are first detected from the DEM surface by using the structural analysis method. Then, the iterative guided normal filter is used to smooth the generalized DEM with the guidance of the structure of the original surface. After this process, the terrain structure is retained in the smooth surface of the DEM. The experimental results with a real-world dataset show that our method can inherit the merits of both structural analysis and statistical filter in preserving terrain features for multi-scale DEM representations.
New England’s Underutilized Seafood Species: Defining And Exploring Marketplace Potential In A Changing Climate
Creators: name: Davis, Amanda

description: New England’s seafood industry has been searching for opportunities to diversify their landings and build resilience as it faces socio-economic challenges from a changing climate. Developing markets for underutilized species is one way the New England community could help their seafood industry build resilience. This thesis identified New England’s underutilized fish species and explored their marketplace potential by examining their availability in a changing climate, current availability to consumers, and consumers’ responses. In Chapter I, I account how New England’s seafood preferences have changed over time. In Chapter II, I identify New England’s seven underutilized seafood species: 1) Acadian redfish (Sebastes fasciatus), 2) Atlantic pollock (Pollachius virens), 3) butterfish (Peprilus triacanthus), 4) the Georges Bank and Georges Bank East stocks of haddock (Melanogrammus aeglefinus), 5) scup (Stenotomus chrysops 6) the northern stock of silver hake (Mercluccius bilinearis), and 7) white hake (Urophycis tenuis). In the same chapter, I show that climate change will likely affect the availability of these species differently and that the broader ecological and socio-economic responses from shifting distributions and phenology are largely unknown. In Chapter III, I demonstrate that besides haddock, underutilized species were rarely accessible to consumers in restaurants. In the same chapter, I show how resources would likely help consumers and restaurants connect with their underutilized species since popular seafood suggestion guides either overlook or provide inconsistent recommendations for all underutilized species. In Chapter IV, I suggest that younger generations (Millennials and Generation Z) are interested in engaging with underutilized species. These younger consumers responded positively to hake, haddock, and Atlantic pollock in sensory assessments. Finally, in Chapter V, I suggest how New England’s seafood supply chain can use results from this research to make more informed policy, marketing, and purchasing decisions that align with their sustainability goals. These insights into availability, access, and consumer response may help New England’s seafood industry strategize approaches that will connect younger consumers to their local seafood options and build new adaptive markets in a changing climate.

description: The correlation between the two $τ$-polarisations is predicted to be opposite $(+-/-+)$ for the $H/A \to τ^+τ^-$ signal, while it corresponds to the same sign combinations for the Drell-Yan $(++/--)$ and $t \bar t$ $(--)$ backgrounds. We show that this correlation can serve as a distinctive test to confirm the presence of the MSSM Higgs bosons $H$ and $A$ in their hadronic $τ^+τ^-$ decay channels at the LHC.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Quantization of the nonprojectable 2+1D Horava theory: The second-class constraints

description: We present the quantization of the 2+1 dimensional nonprojectable Horava theory. The central point of the approach is that this is a theory with second-class constraints, hence the quantization procedure must take account of them. We consider all the terms in the Lagrangian that are compatible with the foliation-preserving-diffeomorphisms symmetry, up to the z=2 order which is the minimal order indicated by power-counting renormalizability. The measure of the path integral must be adapted to the second-class constraints, and this has consequences in the quantum dynamics of the theory. Since this measure is defined in terms of Poisson brackets between the second-class constraints, we develop all the Hamiltonian formulation of the theory with the full Lagrangian. We found that the propagator of the lapse function (and the one of the metric) acquires a totally regular form. The quantization requires the incorporation of a Lagrange multiplier for a second-class constraint and fermionic ghosts associated to the measure of the second-class constraints. These auxiliary variables have still nonregular propagators.
