La línea justa: el Partido Comunista y el peronismo, 1955-1973

After the 1955 coup that led to the exile of President Juan Domingo Peron, the Argentine Communist Party developed a wide range of tactics to "seduce" the working class, supplementing what the party's central committee understood as the slow but steady leftward migration by an important number of Peronist militants. Through the study of unpublished internal documents and official party publication, this article reconstructs the impact that the recruitment efforts had on the shop floor, around the neighborhood, and in the universities. As a result, the article makes two important contributions: it explores the ideological dilemmas resulting from this approach and its impact on internal party life, and it recreates the fluid relationships between communists and Peronists between 1955 and 1973. Moreover, the article argues for the need to reinscribe the history of communism within the flourishing historiography on the Argentine New Left.

Congenital Vascular Malformation

A 10-year-old girl presented with a history of recurrent painful swelling of the left knee with mild ecchymosis. The latest episode of tender swelling of soft tissue along the left knee was preceded by a direct blow to the area during a ball game. In addition, she has had an abnormally grown left lower limb with scattered multiple soft tissue masses throughout the limb since birth.
Influence of Organizing Strategies, Time, and Grade Point Averages on Retention Performance.

AbstractThe relationships among retention performance, organizing strategy preference, and grade point average were assessed in 227 college students. Highly significant correlation coefficients suggest that the type of organizing strategy used in memorizing exerts a strong influence on the recall of paired associates over both short and long periods of time. Moreover, they seem to indicate that organizing strategy preference has promise as a predictor of grade point average.
Synthesis and Preliminary Anticancer Results for Polymers From the Reaction of Organotin Dihalides and Thiodiglycolic Acid

Organotin polyesters were synthesized in good to poor yield with yield and chain length generally decreasing as the alkyl chain on the organotin increases. MALDI MS, NMR, and IR data is consistent with the proposed repeat unit. MALDI MS ion fragment clusters to four repeat units are found. The IR shows the presence of a new band assigned to the formation of the Sn-O. With the exception of the dimethyltin polymer, all of the polymers exhibit good inhibition of a variety of cancer cell lines including two breast cancer, prostate, two pancreatic cancer and colon cancer cell lines.
Quota Setting in Stochastic Fisheries

The problems of setting quotas in fisheries are discussed in the context of environmental stochasticity impacting the stock, the application of inexact models to assess and predict variables, and the imprecise measurement of these variables. We conclude that substantial experimentation with simulation models needs to be undertaken to assess the consequences of various assumptions in our stock assessment methodology. We also conclude that long term average yield is relatively insensitive to the type of harvesting strategy adopted (eg., constant effort contrasted with constant escapement), and that the most appropriate management policy is determined by socio-political considerations rather than by a precise description of the stock dynamics.
Provision of fluoride varnish treatment by medical and dental care providers: variation by race/ethnicity and levels of urban influence.

Background In 2004, Wisconsin Medicaid policy changed to allow medical care providers to be reimbursed for fluoride varnish treatment (FVT) to children’s teeth to improve access and utilization. To date, no study has been published on whether geographic and racial/ethnic variation in the provision of FVT in response to this policy change exists.
A model of temporal synaptic interactions

The patterned interaction between synaptic inputs on the muscle fibers of crustacean claws has been found to be important in delineating claw behavior. When the excitatory and inhibitory neurons are fired at different frequencies in the opener muscle of the cutter claw of lobster Homarus Americanus, a complex pattern of postsynaptic potentials (PSPs) is observed. To analyze the nature of these varying patterns, an electrical equivalent circuit model of a single cell with two synapses, one excitatory and one inhibitory, is used. This model is implemented using a circuit simulation program. The PSP patterns generated by this model compare favorably with the patterns obtained from experiments. Thus the model can be used to formulate a theoretical basis for such pattern generation. >
Advanced techniques and algorithms for reservoir simulation I: frontier issues in managing oil and gas production

A new paradigm for the management of oil and gas fields is emerging, thanks to advances in a variety of monitoring technologies. Taking advantage of these advances poses a major challenge for the reservoir simulation, both in terms of speed and in terms of the range of physical processes to be modeled. This paper establishes the background for this challenge, and succeeding papers in this series [1, 2, 3] describe approaches for meeting this challenge.
A question of filling in the gaps: a master class commentary.

Abstract “Judy,” a professional writer, asked me to use hypnosis to help her “fill in the gaps” in her knowledge of certain periods in her youth. As she was so keen, getting her into trance was relatively easy. I asked a few questions and she answered in a slurred voice. Then, after a few minutes, she said that she wasn't hypnotized. “Not to worry, Judy, I'll bring you out” was my reply. With that, a flood of memories, absolutely unstoppable for approximately 4 minutes, came pouring forth. There-after, I asked questions relating to an earlier period in her life. Again came the statement that she wasn't hypnotized, and I replied as before. With that, a second flood of unstoppable experiences poured forth. Later, on coming out of trance, she was able to recall all she'd spoken about while in trance and often punctuated her recollections with “I didn't know that they punished me at 6 by locking me in the cupboard under the stairs!”
Indirect anaphora resolution as semantic path search

Anaphora occur commonly in natural language text, and resolving them is essential for capturing the knowledge encoded in text. Indirect anaphora are especially challenging to resolve because the referring expression and the antecedent are related by unstated background knowledge. Such anaphora need to be resolved properly in order to automatically capture the knowledge expressed in natural language. Resolving indirect anaphora has been treated as a unique problem that requires special-purpose methods, and these methods have had limited success in precision and recall. In this study, we used a generic tool for finding semantic paths between two concepts to resolve these anaphora, and it achieved approximately twice the recall of the best previous system without loss of precision. A series of ablation study showed that the biggest increase in recall came from an abductive stopping criterion of the search.
Numerical and theoretical considerations for sensitivity calculation of discontinuous flow

Abstract Linearization of 1-D Euler equations about a discontinuous solution is discussed from both the theoretical and numerical point of view. Estimates for the norm of the solution of the linearized system are shown to be valid for the case presented. Numerically, the linearization is performed following the guidelines of tangent linear model and sensitivities with respect to a flow parameter are computed, being in better agreement with the analytical value when compared with previously reported numerical results.
Carboxylate exchange among dimolybdenum tetracarboxylates: The trifluoroacetate/formate system

Abstract 1 H NMR spectroscopy has been used to study the kinetics and equilibrium properties of solutions, in acetone, made of (CF 3 CO 2 ) 4 Mo 2 and (HCO 2 ) 4 Mo 2 . At equilibrium all of the mixed ligand species, (CF 3 CO 2 ) 3 (HCO 2 )MO 2 , cis - and trans -(CF 3 CO 2 ) 2 (HCO 2 )MO 2 , and (CF 3 CO 2 )(HCO 2 ) 3 Mo 2 , are formed, as well as the end members. The distribution shows almost no significant deviations from that expected statistically, the main one being in a cis/trans ratio in the 2:2 species that is about 2.5 instead of 2.0. At 21°C, equilibrium was attained too rapidly (
Ignition of a combustible half space

A half space of combustible material is subjected to an arbitrary energy flux at the boundary where convection heat loss is also allowed. An asymptotic analysis of the temperature growth reveals two conditions necessary for ignition to occur. Cases of both large and order unity Lewis number are shown to lead to a nonlinear integral equation governing the thermal runaway. Some global and asymptotic properties of the integral equation are obtained.
Solving System Of Linear Equations Using The Bimodal Optical Computer (Experimental Results)

Hardware and software design of the Bimodal Optical Computer (BOC) and its implementations are presented. Experimental results of the BOC for solving a system of linear equations Ax = b is reported. The effect of calibration, the convergence reliability of the BOC, and the convergence of problems with singular matrices are studied.
Pan evaporation and potential evapotranspiration trends in South Florida

Declining trends in pan and lake evaporation have been reported. It is important to study this trend in every region to evaluate the validity of the trend and water management implications. Data from nine pan evaporation sites in South Florida were evaluated to see if there is a trend and if the quality of the data is sufficient for such analysis. The conclusion is that pan evaporation measurements are prone to too many sources of errors to be used for trend analysis. This condition is demonstrated in South Florida and in other regions by differences in magnitude and direction between spatially related pan stations and unexplainable observations. Also, potential evapotranspiration (ETp) was estimated with the Simple (Abtew equation) and the Penman–Monteith method. Both cases indicated no decline in evapotranspiration for the period of analysis. Based on the decline in humidity and the increasing trend in vapor pressure deficit for the short period of analysis, 1992–2009, it appears that South Florida is experiencing increase in evaporation and evapotranspiration at this time assuming no systematic error in the weather stations' observations.

Cryogenic properties of a P/M Ni3Al-B alloy

Polycrystalline Ni/sub 3/Al-based intermetallic alloys have overcome their room temperature brittleness problem with a small amount or boron addition. Because of their unique strength-temperature relationship and good oxidation resistance at high temperatures, research efforts have been concentrated extensively on structural applications at elevated temperatures. In this paper the authors show that ductile Ni/sub 3/Al-B alloys also exhibit remarkable mechanical properties at cryogenic temperatures.
Pressure-induced staging transitions and stage disorder in dilute potassium-graphite intercalation compounds.

We extend our previous study of high-pressure staging transitions and stage disorder to dilute potassium-graphite intercalation compounds, using the Hendricks-Teller analysis of elastic neutron scattering (00L) profiles measured at 300 K over a broad q range. The dilute regime begins at a concentration (K)/(C)approx. <1/33, all samples in this regime behaving qualitatively the same at high pressure. A continuous transition starts immediately near P = 0, leading to a well-ordered higher stage with no apparent connection to in-plane density or structure. This is stable only over a small range, transforming abruptly at slightly higher P to a still higher stage or stage mixture, the index of which is consistent with the specific in-plane density imposed by commensurate 2 x 2 lockin. Disorder generally increases with average stage index (i.e., with increasing P or decreasing (K)/(C) ratio), consistent with the theory of Kirczenow. Disorder in the most dilute samples is better represented by a skewed distribution of many stage packages than by a random mixture of two or three different stage cells.
Experiences mapping and revising curricula with CS2013

1. SUMMARY Roughly once per decade, the ACM and IEEE-Computer Society form a joint task force to survey the discipline and produce curricular guidelines for undergraduate computer science programs. The latest guidelines document, Computer Science Curricula 2013 (CS2013), was released in the Fall of 2013 after multiple rounds of public review and feedback. A significant novel feature of CS2013 is the structuring of the Body of Knowledge core topics into two tiers. While Core-Tier1 topics are expected to be included in every undergraduate computer science program, individual programs may choose to cover only a subset of Core-Tier2 topics, depending upon institutional size, resources, and goals. CS2013 recommends at least 80% coverage of CoreTier2, which provides flexibility for designing curricula that meet institutional constraints while still maintaining disciplinary standards.

A new technique for growing crystals from the vapor

A new method for growing single crystals with sensitive control of supersaturation and minimal influence from foreign surfaces is described.
Heat Transport in Liquid Crystals

Abstract Several reports have appeared during the past half century describing temperature changes of nematic liquid crystals, inparticular p-azoxyanisole, upon exposure to a magnetic field. Although all the experiments were conducted with the sample in good thermal contact with the over or bath, the temeperature changes persisted until the field was removed. It is proposed here that the thermal changes were a result of anisotropy of the thermal conductivity and heat leakage through the temperature measuring device. A new experiment supporting this view is discussed.
Chronic natural killer-cell lymphocytosis successfully treated with alemtuzumab.

To the editor: We describe the first case of chronic natural killer (NK)–cell lymphocytosis (CNKL) successfully treated with alemtuzumab. Our patient is a 62-year-old male diagnosed in 2007 with livedo reticularis, cutaneous polyarteritis nodosa, and peripheral neuropathy. No hepatosplenomegaly
Analysis of the atrial T wave in patients with chronic obstructive pulmonary disease.

The atrial T wave (Ta) was studied by computer analysis in 171 patients with chronic obstructive pulmonary disease (COPD). They were divided into three groups according to Ta amplitude. Group 1 included 98 cases (57.6 percent) with Ta of .05 mv or less, group 2, 38 cases (22.3 percent) with Ta between .06 mv and .09 mv, and group 3, 35 cases (20.5 percent) with Ta of .10 mv or more. The mean Ta for the total group was .05 mv (range .00 mv to .18 mv). Distribution of the three groups according to heart rate, PR interval, P wave amplitude, duration, axis, MVV L/min., VC ml and FEV 1 ml was obtained. Ta amplitude correlated well with heart rate, P wave amplitude and axis. As mean P wave axis shifted rightward, Ta amplitude increased. No correlation was found between the Ta and PR interval or P wave duration. The Ta amplitude correlated well with the pulmonary functions and patients with the greatest reduction in such functions exhibited the highest Ta values. The patients were divided into quartiles on the basis of MVV. The number of patients with Ta of .10 mv or more in quartile 4 (the most severe) was almost double than in quartiles 2 and 3, and about seven times that of quartile 1. Conclusion is that Ta amplitude of .10 mv or more correlated well with COPD and .06 mv or more is highly suggestive.
The short-term course of familial and nonfamilial schizophrenic-spectrum disorder

This study was designed to determine if familial and nonfamilial forms of schizophrenia show a different short-term illness course. Sixteen familial and 22 nonfamilial schizophrenics were evaluated on three occasions at regular 6-month intervals over an 18-month period. The familial and nonfamilial groups were compared for differences in positive and negative symptoms of psychosis and interpersonal and occupational role functioning. The data show that familial schizophrenics experience significantly higher levels of positive symptoms of psychosis and significantly worse occupational role functioning. Significant time by family history interactions indicates that the negative symptoms and interpersonal role functioning of the familial schizophrenics changed over the course of follow-up while remaining stable over time in the nonfamilial group. These data provide preliminary support for the hypothesis that familial schizophrenics show a higher degree of impairment during follow-up than nonfamilial schizophrenics.
Some kinetic and regulatory properties of the pea chloroplast pyruvate dehydrogenase complex

Abstract Results from initial rate studies of the pea chloroplast pyruvate dehydrogenase complex indicate a kinetic mechanism identical to that of bacterial and mitochondrial complexes. Interaction kinetics for all substrates resulted in parallel lines consistent with a multisite ping-pong mechanism. Product inhibition studies showed competitive inhibition between acetyl-coenzyme A and coenzyme A and between NADH and NAD. Uncompetitive inhibition was found between pyruvate and NADH or acetyl-coenzyme A, while noncompetitive inhibition was found for NAD or coenzyme A versus acetyl-coenzyme A and NADH, respectively. Activity of the chloroplast pyruvate dehydrogenase complex could be regulated by product inhibition. The plastid complex was more sensitive to the NADH NAD ratio than the acetyl-coenzyme A/coenzyme A ratio. Additionally, there is the potential for fine regulation of chloroplast pyruvate dehydrogenase complex activity by intermediates and products of fatty acid synthesis.
Settlement, Return, and the Supersession Thesis

In earlier articles, the author developed what is known as the "Supersession Thesis," asserting that historic injustice may be overtaken by changes in circumstances so that a situation that was unjust when it was brought about may coincide with what justice requires at a later time. The Supersession Thesis was developed initially as a tool for considering historic injustice suffered by indigenous peoples in the European settlement of countries like Australia, Canada, New Zealand, and the United States. In this paper, the author explores the application of the Supersession Thesis to issues about the Palestinian right of return and also to Israeli settlements in the Occupied Territories. The paper argues that, while it is not unthinkable that the Supersession Thesis might eventually legitimize the settlements and undermine the Palestinian right of return, there is no guarantee that this will happen. The application of the Supersession Thesis does not depend on the passage of time, but on changes in circumstances that a theory of justice makes relevant. Many of the circumstances that make the Supersession Thesis relevant to the post-colonial situations described (Australia, New Zealand, etc.) do not apply in the Israeli situation. Nevertheless, it is worth considering the possibility of applying the Supersession Thesis in this case, because it enables us to assess the merits of the Thesis more sharply in relation to injustice that is taking place now (or took place in living memory), as opposed to injustice that took place in the nineteenth century.
Efficient biomass pretreatment using ionic liquids derived from lignin and hemicellulose

Ionic liquids (ILs), solvents composed entirely of paired ions, have been used in a variety of process chemistry and renewable energy applications. Imidazolium-based ILs effectively dissolve biomass and represent a remarkable platform for biomass pretreatment. Although efficient, imidazolium cations are expensive and thus limited in their large-scale industrial deployment. To replace imidazolium-based ILs with those derived from renewable sources, we synthesized a series of tertiary amine-based ILs from aromatic aldehydes derived from lignin and hemicellulose, the major by-products of lignocellulosic biofuel production. Compositional analysis of switchgrass pretreated with ILs derived from vanillin, p-anisaldehyde, and furfural confirmed their efficacy. Enzymatic hydrolysis of pretreated switchgrass allowed for direct comparison of sugar yields and lignin removal between biomass-derived ILs and 1-ethyl-3-methylimidazolium acetate. Although the rate of cellulose hydrolysis for switchgrass pretreated with biomass-derived ILs was slightly slower than that of 1-ethyl-3-methylimidazolium acetate, 90–95% glucose and 70–75% xylose yields were obtained for these samples after 72-h incubation. Molecular modeling was used to compare IL solvent parameters with experimentally obtained compositional analysis data. Effective pretreatment of lignocellulose was further investigated by powder X-ray diffraction and glycome profiling of switchgrass cell walls. These studies showed different cellulose structural changes and differences in hemicellulose epitopes between switchgrass pretreatments with the aforementioned ILs. Our concept of deriving ILs from lignocellulosic biomass shows significant potential for the realization of a “closed-loop” process for future lignocellulosic biorefineries and has far-reaching economic impacts for other IL-based process technology currently using ILs synthesized from petroleum sources.
Use of thermal stability studies to compare Bacteroides fragilis lyophilized in skim milk and polyvinylpyrrolidone solutions

Bacteroides fragilis cells suspended in two different suspending media, polyvinylpyrrolidone (PVP) and skim milk (SM) solutions, were lyophilized and evaluated for stabilities through accelerated thermal degradation studies. The lyophilized preparations were exposed to 70, 60, 50, 48, 35, 25, and 4 °C. Modified Arrhenius statistical models were used to compare quantitative estimates (colony forming units) of viability at 4 °C to the observed counts with each medium at that temperature. Results with the PVP suspension were not acceptable. However, the estimated time for the SM preparation to degrade to the observed viability count was within 8 days when data from all seven temperature exposures were used for the calculations.
Effect of column performance on the accuracy of molecular weights obtained from size exclusion chromatography (gel permeation chromatography)

This paper presents a functional molecular weight accuracy criterion for gel permeation chromatography column performance that connects the traditional concepts of column resolution with molecular weight accuracy in gel permeation chromatographic measurements. The criterion predicts accuracy of molecular weights directly from column parameters; conversely it can be used to specify needed column parameters to obtain a selected level of gel permeation chromatography-molecular weight accuracy. According to this accuracy criterion, the performance of the columns can be quantitatively rated in terms of the product of two fundamental column parameters: σ, the standard deviation of the peak (related to the column plate count for a monodispersed polymer), and D2, related to the slope of the linear portion of the chromatographic calibration curve. Use of this σD2 criterion is illustrated with data obtained on different types of column packings and various sets of columns. The effects of pore geometry and column operating variables on the column resolution are discussed in terms of separation and dispersion theories. A quantitative theory for interpreting the effect of packing pore size distribution on gel permeation chromatographic performance was developed. The theory indicates that the effect on D2 diminishes at narrow pore size distribution.
An esthetic masking cement for prosthetic denture clasps

Abstract Acrynamel cement, a relatively opaque dental cement with unusually great adhesive characteristics, was used with considerable success as an esthetic masking coating on the terminal portion of 161 denture clasps. The nonirritating overlay is placed at the chair, sets in ten to twenty-five minutes and has an appearance considerably superior esthetically to that of denture gold. A simple technique for its application is described.
International organizations in higher education: A survey of their library, documentation and information services

The survey describes the information collection and dissemination facilities and activities of the twenty major regional and international organizations, both non-governmental and inter-governmental, involved in higher education. A brief description of the purpose and scope of each organization is given, its library resources are described, and its documentation and information services are characterized.
Selection, Mentorship, and Subsequent Placement of Preliminary Residents Without a Designated Categorical Position in an Academic General Surgery Residency Program

Background Academic general surgery residency programs face a reduction in clinical hours for residents at a time of expanding educational material/clinical programs. To meet these challenges, clinical staffing includes additional faculty, physician extenders, or additional residents. Categorical resident expansion is difficult but there is an ample pool of preliminary first year resident (R1) candidates every match week, and this pool is projected to increase markedly as all medical schools have increased enrollment without any real change to the demographics of available categorical residency positions. Our experience with preliminary R1s without a designated categorical position over the last 8 academic years forms the basis of this report. Methods The University of Colorado-Denver general surgery residency program recruits 8-12 preliminary R1s annually. Most of these are recruited on scramble day, as we found that having individual interview dates for these positions was labor-intensive and did not yield better candidates. Preliminary R1s were mentored in a systematic fashion by the program during the year to focus on career planning. Files for preliminary R1s were reviewed for demographics, medical school of origin, original prematch career goal, successful completion of the intern year, and subsequent categorical residency placement/type. Results We recruited 64 preliminary R1s without a designated categorical position over the past 8 years (16 females and 48 males) with an average age of 30 years old (range 25-45 years). These preliminary R1s attended medical schools throughout the United States (West 24, South 18, Central 11, Northeast 4, or International 7). The average United States Medical Licensing Examination (USMLE) Step 1 test score was 213 (range 185-252). The majority (95%) completed their preliminary year of training or left for a categorical position during the year. Most preliminary R1s (79%) were successfully placed into categorical training programs at the end of the year, with 23% ultimately receiving categorical training at our institution. Four did not complete their preliminary training year due to medical leave or unsatisfactory performance. The categorical positions preliminary R1s obtained include general surgery (n = 7, 15%), surgical subspecialties (n = 31, 65%), and nonsurgical subspecialties (n = 10, 20%). Ultimately, 14 (29%) of preliminary R1s who matched after 1 year did so in their fields of original interest. Conclusions A symbiotic relationship can exist between a general surgery residency program and preliminary R1s. An approach that focuses on scramble day recruitment, frequent mentorship meetings, and an active role in secondary placement results in successful placement into categorical positions for the vast majority. In that regard, we would argue that we have provided equal career mentorship to these graduated students in comparison with their medical schools of origin.
Relaxation and coalescence of two equal-sized viscous drops in a quiescent matrix

Head-on collisions of two equal-sized viscous drops in a biaxial extensional flow were simulated using the boundary integral method in the Stokes flow limit, for capillary numbers of the order of –, typical of flow-induced coalescence experiments. At a certain point in time, during the drainage process, the flow was abruptly stopped and the time-dependent dynamics of drop deformation (relaxation) was followed to discern whether the pair of drops would eventually coalesce. The concept of coalescence probability was used to study the evolution of probable collisions. The polymeric system of polybutadiene (PBd) drops undergoing head-on collisions in a polydimethylsiloxane (PDMS) matrix, previously well-characterized both experimentally and numerically by Yoon et al. (Phys. Fluid, vol. 19, 2007, 102102), in which both fluids were Newtonian under the experimental conditions, was used as our reference. Film shapes, velocity profiles and pressure distributions were studied for initially parabolic or dimpled thin film shapes. It was shown that micrometre-sized drops undergoing relaxation can coalesce in the capillary number range studied, which also included cases of hindered coalescence and cases in which the flow interaction time for the collision was smaller than the drainage time; thus, this phenomenon could influence the final drop size distribution of blends. Further, these findings could be of interest in interpreting stop–strain experiments, in the case of a sudden change in flow conditions and in population balance studies of drops in blends.
A simulation model for the growth and development of flowering rose shoots

Abstract Mathematical models were selected or developed for the physiological processes involved in rose shoot growth and development. These were assembled into a model for simulating the response of rose shoot growth to photosynthetically active radiation and temperature. The patterns of simulated and observed shoot part dry weights were very similar. Dynamic patterns for processes such as leaf growth, assimilate production, import/export of assimilates and respiration were explored. Further work is needed on model refinement and validation.
Collision Studies between Ultracold NaCs Molecules and Composite Atoms

Deeply bound ultracold polar NaCs molecules are electrostatically trapped and spatially overlapped with each magneto-optical trap to induce atom-molecule interactions. The resulting atom-molecule collision studies are presented.
Cerebrovascular Dysfunction Following Sub-Failure Axial Stretch

Cerebral blood vessels are critical in maintaining the health and function of the brain, but their function can be disrupted by traumatic brain injury (TBI), which commonly includes damage to these vessels [1]. However, even in cases where there is not apparent mechanical damage to the cerebral vasculature, TBI can induce physiological disruptions that can lead to breakdown of the blood brain barrier or loss of cerebral autoregulation.Copyright © 2013 by ASME
Provision of Recreational Activities in Hospices in the United States

Quality of life issues encompass the philosophies of both hospice and recreation participation. This study examines the status of recreational activities provision in hospices in the United States. The offering, frequency of offering, and location of offering of 39 recreational activities in a random sample of hospices in the United States were surveyed. The functional levels of participating patients were also recorded. Reading to patients at bedside daily was determined to be the most frequently provided recreational activity. Recreational activities are being offered in 40% of the larger U.S. hospices on a varying schedule in different locations.
Understanding genetic epidemiologic association studies Part 1: Fundamentals

The scientific world has witnessed a fivefold increase in the number of published genomic studies of humans in the past two decades. Major advances in genetics, most notably, the completion of the Human Genome Project in 2001 1, 2 and the International HapMap Project 3–5 in 2003, in conjunction with the rapid advances of genotyping technology, has made it more feasible and less expensive for scientists to perform larger scale genetic epidemiologic association studies of common as well as rare diseases. The implications for patient care are not always readily apparent, but there is an underlying expectation that these types of studies will contribute to the development of individualized medicine, where genomic information is used during consultation to help tailor the treatment plan to the individual. More importantly, these studies may offer insight into the cause of disease under study and enhance our potential for risk stratification, which can ultimately help with local resource allocation. Currently, we practice a “one-size-fits-all” approach to patients. With genomic information, we hope to offer in the future individualized screening recommendations and treatment plans that fall more in line with a “one-size-fits-one” approach. This “future” is currently being played out among several diseases, most notably breast cancer. We now understand and appreciate that in the two genes, breast cancer 1 (BRCA1) 6 and breast cancer 2 (BRCA2) 7 mutations are important risk factors for and predict high probability (about 70% lifetime risk) for early onset hereditary breast cancer. Indeed, women who undergo risk assessment and test positive for hereditary mutations in these genes may elect to have prophylactic bilateral mastectomies. 8, 9 As for the medical oncologic treatment of breast cancer, there are compelling data based on genotyping information that suggests that patients with polymorphisms in the CYP2D6 gene (an enzyme in the P450 pathway that helps to metabolize tamoxifen to its active form endoxifen) might alter the metabolism of the drug, causing low bioavailability of the drug. Women who have a specific CYP2D6 polymorphism tend to have earlier disease recurrence and poorer survival.10, 11 Therefore, clinicians are now faced with the challenge of determining if the data available are robust enough to offer pre-treatment testing for this polymorphism, as it may help to determine if tamoxifen therapy, an accepted part of breast cancer care, will be a part of a patient’s treatment plan. Advances such as these require an understanding of the fundamentals of population-based genetic research in order to interpret the genetic data and apply the findings to patient care. This is the first of a two-part review that provides the fundamentals of genetic epidemiology association studies. Part 1 focuses on defining common terms and concepts used in these studies, and Part 2 focuses on how to critically analyze and interpret the findings of genetic epidemiology association studies.
Real-Time Collision Deformations using Graphics Hardware

We present a method for efficiently simulating minor deformations that result from collisions. Our method alters only bump maps and leaves mesh geometry unchanged. It is well suited to games because although the results are not physically correct, they are plausible and are computed in real-time. In a real-time simulation the CPU already carries a high load due to game logic, I/O, and physical simulation. To achieve high performance, we move the deformation computation off the CPU. The task of computing surface deformations and collisions for physics is very similar to that of rendering computational solid geometry objects. We exploit this observation by "rendering" the intersection to an offscreen buffer using graphics hardware and parallel texture map operations.
A High Sensitivity, Phase Sensitive d33 Meter for Complex Piezoelectric Constant Measurement

Based on the direct piezoelectric effect and signal comparison method, a quasi-static, high sensitivity, phase sensitive d33 meter has been developed. The system is capable of measuring the complex piezoelectric d33 constant down to about 1 pC/N and has a phase resolution of ±0.05°. The advantage of this apparatus is that its operation is almost as easy as that of the commercial Berlincourt d33 meter, hence, it is suitable for everyday routine usage.
Acts of generating and their sources: Predicting the effects of imagery encoding on false recognition errors

In the two experiments reported here the basis of the beneficial effects of generating images on false recognition errors is investigated. Acts of generating (descriptions, images, or both) were manipulated while examining the effects of the source of descriptions guiding imagery generations (participant vs peer). False recognition errors were relatively high across encoding conditions except when imagery generations were based on participants' own descriptions (Experiments 1 and 2). These differences in the acts of generating were not attributable to differences in the cohesiveness of descriptions themselves. Acts of generating led to greater “remember” responses than “know” responses only when participants were not the source of the descriptions used to generate images (Experiment 2). Results highlight the importance of examining the effects of the source of descriptions for guiding imagery (participant or peer) when testing predictions about the effects of imagery encoding on false recognition errors.
Poor outcome of indigent patients with peripartum cardiomyopathy in the United States.

OBJECTIVE: Peripartum cardiomyopathy (PPCM) patients from Haiti and South Africa have poor survival and poor left ventricular (LV) function recovery compared with patients from the United States. There are no reported studies of PPCM among the African American population in the United States. We evaluated the prognosis of PPCM in a mostly African American population. STUDY DESIGN: We analyzed the clinical and echocardiographic data of 44 (39 African American) patients with PPCM over an 11 year period (1992-2003). RESULTS: Thirty-nine patients were indigent and 5 had health insurance. During a mean follow-up of 24.0 (range, 0.1-264) months, 7 (15.9%) patients died and LV function returned to normal in 14 (35%). CONCLUSION: LV function recovery and survival rates of PPCM patients observed in our study are similar to those reported from Haiti and South Africa and different from what is generally accepted in the United States.
DNA sequences near a meiotic recombinational breakpoint within the human HLA-DQ region.

The molecular organization of HLA-DQ regions derived from DR7, DQw2, and DR4, DQw3 parental haplotypes and DR7, DQw3, a presumed recombinant haplotype, have been studied to define the sequences between DQA1 and DQB1 which may have been involved in this recombinational event. The breakpoint was localized in the intergenic region near the 3′ end of the DQB1 gene by restriction mapping. DNA sequences in the immediate vicinity of the breakpoint in DR7, DQw2 (parental), and DR7, DQw3 (recombinant) haplotypes revealed the presence of (CA)22 repeats, minisatellite-related sequences and GC-rich sequences. The intergenic regions varied considerably depending on the haplotype and contained several additional types of repetitive sequences including Alu and LINE repeats. Some of these sequences are related to sequences previously suggested to be involved in meiotic or somatic recombination. In particular, (CA)n repeats, which can adopt the Z-DNA conformation, have previously been shown to promote recombination in several systems.
Effects of a Laughing versus a Nonlaughing Model on Humor Responses in College Students

The generality of the role of imitation learning with respect to humor responses was examined in 48 college students. The students were exposed to either no model, a laughing model, or a nonlaughing model before reading magazine cartoons alone. The students who had observed a laughing model laughed more than the students who had observed a nonlaughing model or no model.
Breast scintigraphy as an imaging modality in the diagnosis of breast masses

The early detection and presurgical diagnosis of breast masses remains a formidable challenge. Recent technologic advances have permitted additional noninvasive means of evaluating the breast in conjunction with physical examination and mammography. We have employed 99m Tc-pertechnetrate breast scanning in selected cases as a complement to mammography when the diagnosis was uncertain. In such cases, the combined use increased the diagnostic accuracy.
MECHANICAL PROPERTIES OF VAPOR-GROWN CARBON FIBER COMPOSITES WITH THERMOPLASTIC MATRICES

This article discusses the mechanical properties of vapor-grown carbon fiber (VGCF)/nylon and VGCF/polypropylene composites. Fibers in the as-produced condition yielded composites with marginally improved mechanical properties. Microscopic examination of these composites clearly showed regions of uninfiltrated fibers, which could account for the unsatisfactory mechanical properties. The infiltration of the fibers by both polymers was improved by carefully ball milling the raw fiber so as to reduce the diameter of the fiber clumps to less than 300 μm. Properties of composites made with ball-milled material were improved in every respect. VGCF reinforcement in nylon slightly improved the tensile strength and doubled the modulus, while VGCF in polypropylene doubled the tensile strength and quadrupled the modulus compared to unreinforced material. Moreover, the composites were sufficiently improved that differences in fiber surface preparation became important. For example, air-etched fibers and fibers covered with low concentrations of aromatics produced polypropylene composites with significantly better mechanical properties than did fibers whose surfaces were heavily coated with aromatics. Both the tensile strength and the modulus of the composites fabricated with clean fibers exceeded theoretical values for composites made with fibers randomly oriented in three dimensions, indicating that the injection-molding process oriented the fibers to some extent.
Global workload characterization of a large scale satellite image distribution system

Online content distribution systems, which store incredibly large amounts of information and provide service to large numbers of users, are becoming increasingly commonplace. To fulfill the wide range of requests sent by different users, these systems must ensure efficient handling of massive amount of data. To achieve this goal, the in-depth analysis and comprehensive understanding of user behaviors are critical. However, analyzing the behaviors of worldwide users with different needs is a very challenging task. This is especially true when historical user behaviors evolve over time or may be affected by unpredictable events. In this paper, we present a number of workload characterization techniques applied to one of the world's largest online satellite image distribution systems operated by the U.S. Geological Survey (USGS) and NASA.
Thermodynamic assessment of heat treatments for a Co-Cr-Mo alloy

Ternary phase diagrams of the Co-Cr-Mo system have been calculated from thermodynamic data. It is shown that from such diagrams, intermetallic phase formation which is detrimental to mechanical behaviour, may be predicted. These calculations may be used to provide a thermodynamic basis for surgical implant alloy design.
A finite mixture model of heterogeneous anchoring with distinct anchoring patterns

Bayesian models of starting price effects in contingent valuation studies have been used to track and to correct for starting price effects for more than two decades. Since then, the single parameter form that has been used to estimate the starting price effect has been adapted to distinguish among strategically induced, Bayesian or yea-saying responses (Whitehead, 2002). Recent works, however, show that these diagnostics can be inaccurate if heterogeneity exists in the value of the updating parameter. This work allows a more flexible functional form, beyond the single updating parameter, to capture a potentially richer set of starting price effects that may operate in a single dataset. First we employ a finite mixture model to sort respondents into latent classes. The finite mixture model locates three distinct types (latent classes) of respondents, and each exhibits a discretely different starting price-affected behaviour in a subsequent regression. Heterogeneity does not follow a continuous distributio...
A Wide-Range Adjustable-Speed Drive

This paper describes the theory and characteristics of a drive which provides a wide range of adjustable speeds. The ratio of the maximum to minimum useful speeds attainable is approximately 20-to-1. The system provides high starting-torque, relatively high efficiencies and rapid deceleration through regenerative braking. The drive uses d-c series motors and generators and it can be assembled from standard equipment.
Brokers, consumers and the internet: how North American consumers navigate their infertility journeys

North Americans who suffer infertility often reach an end to treatment options at home, whether it is due to a lack of egg donors in Canada or the high cost of treatment in the USA. Patients navigate their way onto the internet, seeking support and other options. As women and couples 'do the research' online, they conduct endless Google searches, come across IVF brokers, join support groups, read blogs and meet others on the road of infertility. This paper considers the journeys that North American patients make to clinics in Moravia, Czech Republic. Along these travels, patients engage with support groups, other patients, IVF brokers and clinic co-ordinators. Since the distance travelled between North America and Europe is extensive, reproductive travels may be arranged by clinical staff, travel brokers and patients. Acting as consumers, North Americans make different 'choices' along their journeys – the use of a broker, if and when they should join online communities, which clinic to visit and where to stay. This study focuses on the question of how patient choices often determine the success of brokers and clinics, thus influencing the structure of cross-border reproductive care in the Czech Republic.
Spectral Nevanlinna-Pick interpolation theory and robust stabilization

In this note we will discuss a new kind of interpolation theory in which one bounds the spectral radius of the matrix-valued interpolating functions instead of the norm as is the case with ordinary Nevanlinna-Pick interpolation. We show how this is related to certain kinds of multivariate stability margin problems of the kind considered by Doyle [2] and Safonov [8].
Temporal and Spatial Compensation techniques for Brighter Entanglement Sources

We report on using temporal compensation to improve the entanglement from two-crystal type-I pulsed, cw-diode and LED sources, using both BBO and BiBO. The fidelity of these sources can be further increased by spatially compensation.
On weak time-symmetric gravitational waves

Abstract The existence and the nature of the solutions of the initial value condition for the time-symmetric pure gravitational waves are investigated. It is shown that, corresponding to any nonsingular three-dimensional metric which is sufficiently close to the flat metric, there exists one and only one nonsingular solution of the initial value condition which is conformal to that metric. It is further shown that the energy of such gravitational waves is positive definite provided that the original metric is chosen sufficiently close to the flat metric.
