Early coagulopathy predicts mortality in trauma.

BACKGROUND Coagulopathy and hemorrhage are known contributors to trauma mortality; however, the actual relationship of prothrombin time (PT) and partial thromboplastin time (PTT) to mortality is unknown. Our objective was to measure the predictive value of the initial coagulopathy profile for trauma-related mortality. METHODS We reviewed prospectively collected data on trauma patients presenting to a Level I trauma center. A logistic regression analysis was performed of PT, PTT, platelet count, and confounders to determine whether coagulopathy is a predictor of all-cause mortality. RESULTS From a trauma registry cohort of 20103 patients, 14397 had complete disposition data for initial analysis and 7638 had complete data for all variables in the final analysis. The total cohort was 76.2% male, the mean age was 38 years (range, 1-108 years), and the median Injury Severity Score was 9. There were 1276 deaths (all-cause mortality, 8.9%). The prevalence of coagulopathy early in the postinjury period was substantial, with 28% of patients having an abnormal PT (2994 of 10790) and 8% of patients having an abnormal PTT (826 of 10453) on arrival at the trauma bay. In patients with disposition data and a normal PT, 489 of 7796 died, as compared with 579 of 2994 with an abnormal PT (6.3% vs. 19.3%; chi2 = 414.1, p < 0.001). Univariate analysis generated an odds ratio of 3.6 (95% confidence interval [CI], 3.15-4.08; p < 0.0001) for death with abnormal PT and 7.81 (95% CI, 6.65-9.17; p < 0.001) for deaths with an abnormal PTT. The PT and PTT remained independent predictors of mortality in a multiple regression model, whereas platelet count did not. The model also included the independent risk factors age, Injury Severity Score, scene and trauma-bay blood pressure, hematocrit, base deficit, and head injury. The model generated an adjusted odds ratio of 1.35 for PT (95% CI, 1.11-1.68; p < 0.001) and 4.26 for PTT (95% CI, 3.23-5.63; p < 0.001). CONCLUSION The incidence of coagulation abnormalities, early after trauma, is high and they are independent predictors of mortality even in the presence of other risk factors. An initial abnormal PT increases the adjusted odds of dying by 35% and an initial abnormal PTT increases the adjusted odds of dying by 326%.
Shaping the US Academic Accounting Research Profession: The American Accounting Association and the Social Construction of a Professional Elite

Abstract For more than two decades there has been continuous debate about the lack of relevance academic accounting research to both education and practice. This has led to normative prescriptions for research to be meaningfully integrated with these other functions. Despite considerable analysis, accountants have failed to provided a convincing explanation of either the current role of academic research or its relative isolation. The paper addresses this issue by seeking an explanation in the research of Bourdieu (1988) and Whitley (1984). In particular, the development of academic accounting research is observed in the competitive environment of the university field of social space. Using the history of the American Accounting Association as an empirical foundation, the analysis identifies the existence of an elite group of researchers within the US accounting education community, and its facilitation by the Association. It questions the long-term maintenance of the current position.
IMAGE MEASURES OF INFINITE PRODUCT MEASURES AND GENERALIZED BERNOULLI CONVOLUTIONS

We examine measure preserving mappings f acting from a probability space (,F,µ) into a probability space ( ∗ ,F ∗ ,µ ∗ ), where µ ∗ = µ(f −1 ). Conditions on f, under which f preserves the relations ”to be singular”and ”to be absolutely continuous”between measures defined on (,F) and corresponding image measures, are investigated. We apply the results to investigate the distribution of the random variable � = ∞ P k=1
Patellar Tendinopathy and Potential Risk Factors: An International Database of Cases and Controls

Objectives: Numerous risk factors have been identified for patellar tendinopathy (PT), often in small population studies. The aim was to use an international online questionnaire to generate a large database and identify significant risk factors. Design: Case–control study. Setting: Private practice and sporting teams recruited from England, Spain, and Italy with the questionnaire available in all 3 languages (equivalence between online and self-administration shown previously). All data were anonymized and password protected. Participants: Eight hundred twenty-five data sets collected between January 2012 and May 2014. Assessment of Risk Factors: A total of 23.4% of participants had clinically diagnosed PT. A comparison between these participants and participants without PT was made. Main Outcome Measure: Association between the presence of PT and risk factors. Results: Eight risk factors were included in the analysis based on a purposeful selection procedure: sex, hours of training, hamstring flexibility, previous patellar tendon rupture, previous knee injury, current/previous back pain, family history, and age. Four were found to have statistically significant odds ratios: female sex [0.70, 95% confidence interval (CI), 0.49-1.00, P = 0.05], hours of training (>20 hours 8.94, 95% CI, 4.68-17.08, P < 0.01), previous knee injury (2.10, 95% CI, 1.45-3.04, P < 0.01), and flexible hamstrings (0.61, 95% CI, 0.38-0.97, P = 0.04). There was a trend toward association for back pain (1.45, 95% CI, 0.99-2.14, P = 0.06) and a family history of tendon problems (1.51, 95% CI, 0.96-2.37, P = 0.08). Conclusions: Risk factors have been identified that are potentially modifiable to inform prevention and rehabilitation programs; future research is required to establish causal relationships. Identified risk factors require mechanistic investigation as they are not currently recognized in the literature.
Applying Attack Graphs to Network Security Metric

Since attack graphs provide practical attack context and relationships among vulnerabilities, researchers have been trying to evaluate network security based on attack graphs. However, previous works focus their attention on specific evaluations they concerned, and each does things in his own way. There is no explicit way telling network administrators how to measure network security in a general way. In this paper, we propose a new metric framework, whose main goal is to guide people to perform evaluations based on attack graphs. The main components of proposed metric framework include Security Index, Target of Evaluation, Elementary Attribute, Composition Algorithm, and Arithmetic operators. Relative definitions and analysis of these five components are also given. The following examples show the applications of our metric framework, and validate it.
Disparities in Postacute Stroke Rehabilitation Disposition to Acute Inpatient Rehabilitation vs. Home: Findings from the North Carolina Hospital Discharge Database

Gregory PC, Han E: Disparities in postacute stroke rehabilitation disposition to acute inpatient rehabilitation vs. home: findings from the North Carolina Hospital Discharge Database. Am J Phys Med Rehabil 2009;88:100–107. Objective:We evaluated the factors associated with discharge disposition to either inpatient rehabilitation or home after acute stroke hospitalization. Design:We analyzed data from three concurrent years of State Hospital Discharge Data (years 2002–2004) of patients admitted with a primary International Classification of Diseases-9 code diagnosis of 430–434.9 and 436 (n = 7810). Logistic regression models tested whether discharge to inpatient rehabilitation vs. home was associated with socio-demographic factors. We controlled for covariates, including medical factors, such as number of intensive care unit days, Charlson Comorbidity Index, therapy charges, and available resources in their county. Results:We found that older age, a greater number of intensive care unit days, higher total therapy charges, and lower poverty in their county of residence were associated with discharge to acute inpatient rehabilitation. Factors associated with discharge to home included younger age, fewer intensive care unit days, lower therapy charges, and higher poverty in their county of residence. Conclusions:Enabling factors, such as county poverty status and exposure to therapy may be important factors related to postacute stroke disposition.
A method for carrier frequency and phase synchronization of two autonomous cooperative transmitters

Cooperative communication protocols in which two or more sources transmit simultaneously in a single subchannel offer the potential for increased power efficiency and achievable rate with respect to orthogonal transmit cooperation. These protocols are, however, complicated by the fact that they require strict transmitter synchronization in order for the carrier signals from each source to arrive in phase and constructively combine at the intended destination. This paper develops an explicit method for synchronizing the carriers of two sources in a cooperative communication system with one destination. Unlike the prior work in this area, the approach described in this paper allows for source and/or destination mobility. The performance of the proposed carrier synchronization system is investigated for several channel models and practical design considerations are also discussed.
Facial emotion recognition using min-max similarity classifier

Recognition of human emotions from the imaging templates is useful in a wide variety of human-computer interaction and intelligent systems applications. However, the automatic recognition of facial expressions using image template matching techniques suffer from the natural variability with facial features and recording conditions. In spite of the progress achieved in facial emotion recognition in recent years, the effective and computationally simple feature selection and classification technique for emotion recognition is still an open problem. In this paper, we propose an efficient and straightforward facial emotion recognition algorithm to reduce the problem of inter-class pixel mismatch during classification. The proposed method includes the application of pixel normalization to remove intensity offsets followed-up with a Min-Max metric in a nearest neighbor classifier that is capable of suppressing feature outliers. The results indicate an improvement of recognition performance from 92.85% to 98.57% for the proposed Min-Max classification method when tested on JAFFE database. The proposed emotion recognition technique outperforms the existing template matching methods.
Relative Effects of Color-, Texture-, and Density-Coding on Visual Search Performance and Subjective Preference

Previously, it had been found that texture-coding was ineffective at reducing search time (Perlman & Swan, 1993). In the experiment reported here, 16 subjects searched for blank-, color-, texture-, and density-coded targets of varying complexity in a naturalistic task. The data showed that all non-blank methods were significantly and about equally more effective at reducing search time than blank-coding (no coding). The difference of outcome with previous results is explained by task simplification and by the control of possibly confounding factors. The difference suggests that coding techniques using texture, and possibly other methods, should be evaluated in context. The similar performance of color-, texture-, and density-coding is explained by the use of equal-saturation and equal-brightness colors. Recommendations for the design of effective coding methods and for future research are discussed.
Kinematic analysis of articulatory coupling in acquired apraxia of speech post-stroke

Primary objective: Electromagnetic articulography was employed to investigate the strength of articulatory coupling and hence the degree of functional movement independence between individual articulators in apraxia of speech (AOS). Methods and procedures: Tongue-tip, tongue-back and jaw movement was recorded from five speakers with AOS and a concomitant aphasia (M= 53.6 years; SD = 12.60) during /ta, sa, la, ka/ syllable repetitions, spoken at typical and fast rates of speech. Covariance values were calculated for each articulatory pair to gauge the strength of articulatory coupling. The results obtained for each of the participants with AOS were individually compared to those obtained by a control group (n= 12; M= 52.08 years; SD = 12.52). Comparisons were made between the typical rate productions of the control group and the typical and fast rate productions of the participants with AOS. Main outcomes and results: In comparison to the control group, four speakers with AOS exhibited significantly stronger articulatory coupling for alveolar and/or velar speech targets, during typical and/or fast rate conditions, suggesting decreased functional movement independence. Conclusions: The reduction in functional movement independence might have reflected an attempt to simplify articulatory control or a decrease in the ability to differentially control distinct articulatory regions.
Which Box(es) Do I Check? Investigating College Students’ Meanings Behind Racial Identification

Abstract How students racially identify continues to be critical for tracking and monitoring disparities in a number of outcomes. Little is known, however, about the meanings of race students enact when encountering the ubiquitous “race questions” used to operationalize these groups. This mixedmethods study explored college students’ (N = 637) underlying meanings behind racial identification, finding six distinct patterns of racial meanings that provide insight into the fluidity of racial demographics and implications for practice.
Contacting a 19 month‐old mute autistic girl: A clinical narrative

Conveying that psychoanalysis offers rich opportunities for the very early treatment of autistic spectrum disorders, this clinical communication unfolds the clinical process of a 19 month‐old ‘shell‐type’ encapsulated mute autistic girl. It details how, in a four‐weekly‐sessions schedule, infant Lila evolved within two years from being emotionally out‐of‐contact to the affective aliveness of oedipal involvement. Following Frances Tustin's emphasis on the analyst's ‘quality of attention’ and Justin Call's advice that in baby–mother interaction the infant is the initiator and the mother is the follower, it is described how the analyst must, amid excruciating non‐response, even‐mindedly sustain her attention in order to meet the child half‐way at those infrequent points where flickers of initiative on her side are adumbrated. This helps attain evanescent ‘moments of contact’ which coalesce later into ‘moments of sharing’, eventually leading to acknowledgment of the analyst's humanness and a receptiveness for to‐and‐fro communication. Thus the ‘primal dialogue’ (Spitz) is reawakened and, by experiencing herself in the mirror of the analyst, the child's sense of I‐ness is reinstated. As evinced by the literature, the mainstream stance rests on systematic early interpretation of the transference, which has in our view strongly deterred progress in the psychoanalytic treatment of autistic spectrum disorders.
Fault Detection of Linear Bearings in Brushless AC Linear Motors by Vibration Analysis

Electric linear motors are spreading in industrial automation because they allow for direct drive applications with very high dynamic performances, high reliability, and high flexibility in trajectory generation. The moving part of the motor is linked to the fixed part by means of linear bearings. As in many other electric machines, bearings represent one of the most vulnerable parts because they are prone to wear and contamination. In the case of linear roller bearings, this issue is even more critical as the rail cannot be easily fully enclosed and protected from environmental contamination, unlike the radial rotating bearing counterpart. This paper presents a diagnostic method based on vibration analysis to identify which signature is related to a specific fault.
Expression of the protein zero myelin gene in axon-related Schwann cells is linked to basal lamina formation.

A Schwann cell has the potential to differentiate into either a myelinating or ensheathing cell depending upon signals received from the axon that it contacts. Studies focusing on the pathway leading to myelination demonstrated that Schwann cells must form a basal lamina in order to myelinate an axon. In this report, we describe studies that indicate that initiation of basal lamina synthesis is required for Schwann cells to distinguish between myelination-inducing axons and axons that do not induce myelination, and to respond by undergoing the appropriate genetic and cellular changes. We have used high resolution in situ hybridization, immunocytochemistry and electron microscopy to examine changes in gene expression and morphology of Schwann cells differentiating into myelin-forming cells in vitro. These experiments were carried out in dorsal root ganglion neuron/Schwann cell co-cultures maintained in either serum-free, serum-only or serum-plus-ascorbate-containing medium. We have made four novel observations that contribute significantly to our understanding of how basal lamina and myelination are linked. (1) The addition of ascorbate (in the presence of serum), which promotes basal lamina production, appears to induce expression of the protein zero gene encoding the major structural protein of myelin. Moreover, expression of protein zero mRNA and protein, and its insertion into myelin membranes, occurs only in the subset of Schwann cells contacting myelination-inducing axons. Schwann cells in contact with axons that do not induce myelination, or Schwann cells that have not established a unitary relationship with an axon, do not express protein zero mRNA although they produce basal lamina components. (2) In serum-free conditions, a majority of Schwann cells express protein zero mRNA and protein, but this change in gene expression is not associated with basal lamina formation or with elongation of the Schwann cell along the axon and elaboration of myelin. (3) In the presence of serum (and the absence of ascorbate), Schwann cells again fail to form basal lamina or elongate but no longer express protein zero mRNA or protein. (4) Myelin-associated glycoprotein and galactocerebroside, two additional myelin-specific components, can be expressed by Schwann cells under any of the three culture conditions. Therefore, we have demonstrated that axonal induction of protein zero gene expression in Schwann cells is subject to regulation by both serum- and ascorbate-dependent pathways and that not all myelin-specific proteins are regulated in the same manner.

A mutation at one end of Moloney murine leukemia virus DNA blocks cleavage of both ends by the viral integrase in vivo

The integration of retroviral DNA proceeds through two steps: trimming of the termini to expose new 3' OH ends, and the transfer of those ends to the phosphates of target DNA. We have examined the ability of the Moloney murine leukemia virus integrase protein (IN) to trim the termini of the preintegrative DNA of mutant viruses with alterations in the U3 inverted repeat. The mutant terminus of one replication-defective viral DNA, containing a 7-bp deletion in the U3 inverted repeat, was not trimmed to produce the normal recessed end. Remarkably, the other terminus of this mutant DNA was also not trimmed, even though its sequence is wild type. This finding suggests that the IN protein requires the presence of two good ends before becoming properly activated to trim either one.
The acquisition of case morphology in German

This paper traces the acquisition of case morphology and isolates taskstructure variables which influence the course of development. The central factors to be discussed belong to both the language periphery of German (fusion within the specifier system ofNPs, homonymy, degree of perceptual similarity, idiosyncracies) and complexities involving parameters and principles of core grammar (government, abstract case assignment, etc.). It is claimed that the learner constructs the morphological case system by searching for correlations across various linguistic subsystems. The relative straightforwardness with which individual cases correlate with formal grammatical principles turns out to be a reliable index of the difficulties encountered by the learner.
The politics and policy of the Third Wave: new technologies and society

We outline the political implications of the program known as the ‘Third Wave of Science Studies’. Here we develop the politics of the Third Wave showing how it bears on technological decision-making in the public domain. The main concern is to combat ‘technological populism’. The prescriptions that emerge include asking and answering as many technical questions as is reasonable and giving these questions and answers the maximum exposure before making what is always a political decision. The implication is a preference for democracies which actively promote discussion and debate of technical matters yet which reject populism of all kinds while still rejecting technocracy. Central to the overt politics of the Third Wave is ‘elective modernism’ which includes scientific values among those which should be at the heart of a good society.
Welfare Improving Coordination of Fiscal and Monetary Policy

Should independent monetary and fiscal policies coordinate their actions and/or targets? To examine this question the paper considers a simple reduced-form model in which monetary and fiscal policies are formally independent, but still interdependent—through their mutual spillovers. The analysis shows that the medium-run equilibrium levels of inflation, deficit, and output depend on the two policies’ (i) potency (elasticity of output with respect to the policy instruments), (ii) ambition (the level of their output target), and (iii) conservatism (inflation vs. output volatility aversion). What matters is however the relative degrees of these characteristics across the two policies rather than the absolute degrees for each policy. This implies that coordination of monetary and fiscal policy is superior to non-cooperative Nash behaviour. In particular, we find that ambition-coordination is more important than conservatism-coordination in terms of avoiding medium-run imbalances due to a tug-of-war betw een the policies. For this reason, and perhaps surprisingly, ambition-coordination can be welfare improving even if the policymakers’ objectives are idiosyncratic, and their coordinated output targets differ from the socially optimal value.
