Classification of Simple Current Invariants

We summarize recent work on the classification of modular invariant partition functions that can be obtained with simple currents in theories with a center (Z_p)^k with p prime. New empirical results for other centers are also presented. Our observation that the total number of invariants is monodromy-independent for (Z_p)^k appears to be true in general as well.

Minimal Models from W-Constrained Hierarchies via the Kontsevich-Miwa Transform

A direct relation between the conformal formalism for 2d-quantum gravity and the W-constrained KP hierarchy is found, without the need to invoke intermediate matrix model technology. The Kontsevich-Miwa transform of the KP hierarchy is used to establish an identification between W constraints on the KP tau function and decoupling equations corresponding to Virasoro null vectors. The Kontsevich-Miwa transform maps the $W^{(l)}$-constrained KP hierarchy to the $(p^\prime,p)$ minimal model, with the tau function being given by the correlator of a product of (dressed) $(l,1)$ (or $(1,l)$) operators, provided the Miwa parameter $n_i$ and the free parameter (an abstract $bc$ spin) present in the constraints are expressed through the ratio $p^\prime/p$ and the level $l$.Comment: 11 pp REVISED (minor changes in the presentation, easier to read

Constraints on extra dimensions from precision molecular spectroscopy

Accurate investigations of quantum level energies in molecular systems are shown to provide a test ground to constrain the size of compactified extra dimensions. This is made possible by the recent progress in precision metrology with ultrastable lasers on energy levels in neutral molecular hydrogen (H$_2$, HD and D$_2$) and the molecular hydrogen ions (H$_2^+$, HD$^+$ and D$_2^+$). Comparisons between experiment and quantum electrodynamics calculations for these molecular systems can be interpreted in terms of probing large extra dimensions, under which conditions gravity will become much stronger. Molecules are a probe of space-time geometry at typical distances where chemical bonds are effective, i.e. at length scales of an \AA. Constraints on compactification radii for extra dimensions are derived within the Arkani-Hamed-Dimopoulos-Dvali framework, while constraints for curvature or brane separation are derived within the Randall-Sundrum framework. Based on the molecular spectroscopy of D$_2$ molecules and HD$^+$ ions, the compactification size for seven extra dimensions (in connection to M-theory defined in 11 dimensions) of equal size is shown to be limited to $R_7 < 0.6 \mu$m. While limits on compactification sizes of extra dimensions based on other branches of physics are compared, the prospect of further tightening constraints from the molecular method is discussed

Risk premium: insights over the threshold

The aim of this paper is twofold: First to test the adequacy of Pareto distributions to describe the tail of financial returns in emerging and developed markets, and second to study the possible correlation between stock market indices observed returns and return's extreme distributional characteristics measured by Value at Risk and Expected Shortfall. We test the empirical model using daily data from 41 countries, in the period from 1995 to 2005. The findings support the adequacy of Pareto distributions and the use of a log linear regression estimation of their parameters, as an alternative for the usually employed Hill's estimator. We also report a significant relationship between extreme distributional characteristics and observed returns, especially for developed countries

Assaults in Domestic Violence Incidents Reported to Alaska State Troopers

Originally published in the Alaska Justice Forum 25(3): 1, 7–12 (Fall 2008).This study examined 1,281 cases with an assault charge involving domestic violence reported to Alaska State Troopers in 2004, and excluded any cases reported to local or municipal departments. * Eighty-two percent of reports were handled by three detachment areas: 32% in C — “ Western Alaska, 29% in D — “ Interior Alaska, and 22% in B — “ Southcentral Alaska. Troopers received 80% of the reports, while 20% were received by Village Police Officers, Village Public Safety Officers, or Tribal Police Officers. Eighty-one percent of the assault charges were in the fourth degree. Eighty-four percent of assaults were reported within 24 hours, and 89% of victims and 81% of suspects were interviewed on the day of the report. * Seventy-six percent of suspects were male and 24% were female. On average, suspects were 33 years old and victims were 32 years old. The majority of assaults in domestic violence incidents (86%) were intra-racial. Fifty-seven percent of suspects and 32% of victims used alcohol. Overall, alcohol was involved in 59% of domestic violence incidents reported to Troopers. * Most assaults in domestic violence incidents (75%) occurred between victims and suspects who were staying or living together. The most common forms of violence (disclosed by victims and documented by officers) included pushing, grabbing, or shoving the victim (in 48% of incidents), punching the victim (in 29%), and slapping or hitting the victim (in 28%). Weapons such as knives or guns were rarely used. The most common injuries included bruising (for 38% of victims), lacerations or bite marks (for 27%), bloody nose or lips (for 10%), and black or swollen eyes (for 10%). Forty-three percent of incidents occurred in the presence of children. * Eighty percent of cases were referred to the Alaska Department of Law for prosecution, 68% were accepted for prosecution, and 54% resulted in a conviction. Overall conviction rates were slightly lower for female suspects, but conviction rates were generally not affected by victim gender or victim-suspect relationship

Alaska Victimization Survey: 2011 Results for Bristol Bay

This is a handout of a Powerpoint slide presentation providing an overview of key results from the 2011 Alaska Victimization Survey for the Bristol Bay region, which was conducted from April to June 2011, with results released on October 12, 2011 in Dillingham. Findings include: * Over 50% of adult women in the Bristol Bay Region have experienced intimate partner violence, sexual violence or both, in their lifetime; * Nearly 15% have experienced intimate partner violence, sexual violence or both, in the past year; * 3 out of every 10 adult women in the Bristol Bay Region have experienced sexual violence in their lifetime; and * 4 out of every 10 have experienced intimate partner violence in their lifetime.Council on Domestic Violence and Sexual Assault, Alaska Department of Public SafetyAlaska Victimization Survey in Bristol Bay / Intimate Partner Violence Definitions / Intimate Partner Violence Estimates / Sexual Violence Definitions / Sexual Violence Estimates / Summary of Past Year Estimates / Summary of Lifetime Estimates / Lifetime Estimates / Important Limitations / A Special Thank You! / Contact

Alaska Victimization Survey: From Research to Policy and Practice

This project was supported by the Alaska Council on Domestic Violence and Sexual Assault. Points of view in this document are those of the authors and do not necessarily represent the official position or policies of the Council, the Alaska Department of Public Safety, or the State of Alaska.The Justice Center at the University of Alaska Anchorage partnered with the Council on Domestic Violence and Sexual Assault to conduct a statewide victimization survey. The Alaska Victimization Survey was modeled after the National Intimate Partner and Sexual Violence Surveillance System (NISVSS) survey, developed by the Centers for Disease Control and Prevention in collaboration with the National Institute of Justice and the Department of Defense. The NISVSS survey is designed to “generate accurate and reliable lifetime and 12-month incidence and prevalence estimates on intimate partner violence (physical aggression, psychological aggression, and sexual violence); sexual violence (unwanted sexual situations, abusive sexual contact, and completed or attempted sex without consent); and stalking” (CDC). This poster presents key results from the Alaska Victimization Survey and identifies how survey results are being used to impact policy and practice.Council on Domestic Violence and Sexual Assault, Alaska Department of Public SafetyAbstract / UCR Forcible Rape Statistice: 1996–2009 / Survey Methods / Measures / Results / Dissemination / Impact on Policy & Practic

Asymmetric Gepner Models II. Heterotic Weight Lifting

A systematic study of "lifted" Gepner models is presented. Lifted Gepner models are obtained from standard Gepner models by replacing one of the N=2 building blocks and the $E_8$ factor by a modular isomorphic $N=0$ model on the bosonic side of the heterotic string. The main result is that after this change three family models occur abundantly, in sharp contrast to ordinary Gepner models. In particular, more than 250 new and unrelated moduli spaces of three family models are identified. We discuss the occurrence of fractionally charged particles in these spectra.Comment: 46 pages, 17 figure
