Assessing Stress in Cancer Patients

Using the Perceived Stress Scale (PSS), perceptions of global stress were assessed in 111women following breast cancer surgery and at 12 and 24 months later. This is the first study to factor analyze the PSS. The PSS data were factor analyzed each time using exploratory factor analysis with oblique direct quartimin rotation. Goodness-of-fit indices (root mean square error of approximation [RMSEA]), magnitude and pattern of factor loadings, and confidence interval data revealed a two-factor solution of positive versus negative stress items. The findings, replicated across time, also indicate factor stability. Hierarchical factor analyses supported a second-order factor of “perceived stress. ” This alternative factor model of the PSS is presented along with observations regarding the measure’s use in cancer research.
Special Issue on Corporate Transformation in the People's Republic of China: Guanxi Practices and Trust in Management: A Procedural Justice Perspective

Taking a procedural justice perspective, we examined the effect of guanxi practices in human resources management (i.e., making human resources management decisions on the basis of personal relationships) on employees' trust in management in Chinese organizations. Two studies were conducted. In the first, a survey study, we found a negative effect of guanxi practices on trust in management, which was mediated by perceived procedural justice. In the second, an experimental study, we found that the negative effect of guanxi practices varied as a function of guanxi bases: favoring a nephew or a hometown fellow lowered trust, but favoring a college schoolmate or a close friend did not. Theoretical and practical implications are discussed.
Design and performance of a THz emission and detection setup based on a semi-insulating GaAs emitter

We have built a relatively simple, highly efficient, THz emission and detection system centered around a 15 fs Ti:sapphire laser. In the system, 200 mW of laser power is focused to a 120 μm diam spot between two silverpaint electrodes on the surface of a semi-insulating GaAs crystal, kept at a temperature near 300 K, biased with a 50 kHz, ±400 V square wave. Using rapid delay scanning and lock-in detection at 50 kHz, we obtain probe laser quantum-noise limited signals using a standard electro-optic detection scheme with a 1-mm-thick (110) oriented ZnTe crystal or a (110) oriented 0.1-mm-thick GaP crystal. The maximum THz-induced differential signal that we observe is ΔI/I=7×10−3, corresponding to a THz peak amplitude of 95 V/cm. The THz average power was measured to be about 40 μW, to our knowledge, the highest power reported so far generated with Ti:sapphire oscillators as a pump source. The system uses off-the-shelf electronics and requires no microfabrication techniques.
Deterministic Petri Net Languages as Business Process Specification Language

Today, a wide variety of techniques have been proposed to model the process aspects of business processes. The problem, however, is that many of these are focused on providing a clear graphical representation of the models and give almost no support for complex verification procedures. Alternatively, the use of Petri Nets as a business process modeling language has been repeatedly proposed. In complex business processes the use of Petri Nets has been criticized and the technique is believed to be unable to capture such processes in all aspects. Therefore, in this paper, we introduce the application of Petri Net language theory for business process specification. Petri Net languages are an extension to the Petri Net theory, and they provide a set of techniques to describe complex business processes more efficiently. More specifically, we advocate the application of deterministic Petri Net languages to model the control flow aspects of business processes. The balance between modeling power and analysis possibilities makes deterministic Petri Nets a highly efficient technique, used in a wide range of domains. The proof of their usability, as business process specification language, is given by providing suitable solutions to model the basic and more complex business process patterns [4]. Additionally, some points of particular interest are concisely discussed.
Multilingual BLSTM and speaker-specific vector adaptation in 2016 but babel system

This paper provides an extensive summary of BUT 2016 system for the last IARPA Babel evaluations. It concentrates on multi-lingual training of both deep neural network (DNN)-based feature extraction and acoustic models including multilingual training of bidirectional Long Short Term memory networks. Next, two low-dimensional vector approaches to speaker adaptation are investigated: i-vectors and sequence-summarizing neural networks (SSNN). The results provided on three Babel Year 4 languages show clear advantage of both approaches in case limited amount of training data is available. The time necessary for the development of a new system is addressed too, as some of the investigated techniques do not require extensive re-training of the whole system.
Face Recognition Performance Analysis: Impact of number of training samples and trade-off between number of individuals and images per individual

We present a performance analysis of face recognition by showing the impact on a recognition performance of the number of training samples and trade-off between the number of individuals and images per individual. We investigate how the recognition performance depends on factors such as the number of individuals in the training set or the number of training images per individual. We will do that by using a face recognition system based on PCA and LDA.
Trend Tests in Epidemiology: P‐Values or Confidence Intervals?

Frequently, p-values are used in reporting epidemiological trend data. Because a p-value is a confounded mixture of effect size and sample size in dichotomous data, Lang, Rothman, and Cann (1998) recommended the slope of a trend line with its standard error and a graphical presentation containing the rate ratios as a function of mid-exposure levels. However, the slope contains the assumption of a dose-response function. This article discusses a proposal based on odds ratios and the corresponding one-sided lower confidence intervals for pair-wise comparisons (‘exposure levels with zero exposure’) as well as comparisons between incremental exposure levels. The proposed method allows both decisions on the global trend, the lowest-observed-adverse-effect-level (LOAEL) and the non-observed-adverse-effect-level (NOAEL), and a simple exploratory analysis.
PC-KIMMO: A Two-Level Processor for Morphological Analysis

This package is a faithful implementation of Koskenniemi's two-level morphology, KIMMO (Koskenniemi 1983). As with previous tools from the Summer Institute of Linguistics (e.g., Weber, Black, and McConnel 1988), the package is primarily aimed at field linguists with little computational expertise, but for whom morphological analysis tools are useful. The book that accompanies the software is extremely good: among other things, it incorporates what is in my opinion the best available introduction to the theory and practice of two-level morphology. The package is therefore not only useful to the audience for which it is primarily intended: it will also be of use to those wishing to learn something about computational morphology, and would be an excellent teaching aid for a computational linguistics course. The book is divided into seven chapters and three appendices. Chapter 1 traces the history of computational morphology. As is typical of such overviews, the scope is somewhat narrow, discussing only a few Finnish projects (besides the work of Koskenniemi and his apostles), and work done at the Summer Institute of Linguistics. That criticism aside, the rest of the chapter is an accurate overview of the positive and negative aspects of KIMMO. On the negative side, Antworth cites the well-known fact that KIMMO cannot elegantly handle nonconcatenative morphology such as infixation or reduplication. He also notes limitations more particular to the PC-KIMMO implementation, such as the lack of a rule compiler and the lack of a sensible (i.e., non-finite-state) model of morphotactics; both of these issues have received treatment within the two-level school (Dalrymple et al. 1987, Bear 1986, inter alia), though with respect to rule compilation, Antworth is justified in noting (p. 11) that "it remains to be seen if such a project is feasible for small computers. " Chapter 2 is an introduction to PC-KIMMO, and gives a sample session of its use. Chapters 3 through 5 describe in detail how finite state transducers (FSTs) work,
Power Management With a Low-Ripple High-Conversion-Ratio 80-V Output Voltage Boost Converter for Avalanche Photodiode System

Avalanche photodiodes (APDs) accompanied with the transimpedance amplifiers (TIAs) are often utilized as receivers in the communication system. A drawback of APDs is that the avalanche gain depends on temperature and varies with the bias voltage, leading to a decrease in the quality of communication. Moreover, the bias voltage for a high avalanche gain is up to 80 V, implying that a power module is inevitably required and raises the difficulty of integration. Therefore, a power management is proposed to provide an 80-V voltage and compensates the temperature dependence for a constant avalanche gain. The low-ripple high-conversion-ratio boost converter eliminates the LC resonance resulted from the nonideal effect of diodes to supress the output voltage ripple, implying that a high quality of bias voltage is guaranteed. Experimental results show that the output voltage ripple is 2.12 mV under the condition of 1-mA load current. A 97% accuracy of avalanche gain is proved to guarantee the high quality of APDs.
Occupational Complexity and Leisure Activities in Cognitive Aging

: Human beings possess a considerable reserve capacity that allows them to benefit from exposure to highly enriched environments. The hypothesis of environmental complexity states that those individuals involved in activities that require greater cognitive demands keep their cognitive abilities undamaged despite the passing of time. The aim of this review is to present an analysis of the results obtained from empirical research made between 1980 and 2014 in Europe and America, focusing on the impact that cognitive reserve has on older adults. This review will demonstrate how environmental complexity and the importance of engaging in recreational activities influence individuals’ lives and their cognitive healthy aging. Bibliography was obtained systematically, through a defined search strategy of several data bases. Ninety one scientific articles were selected in agreement with the appropriateness they keep with the objective of the present research. In regard to pharmacological treatment, there is little evidence that cholinesterase inhibitor drugs affect progression to dementia or improve cognitive performance of patients with MCI. Complementarily, mixed results have been reported from different research lines that use cognitive training. Besides, there is increasing evidence that consider the role of environment and lifestyle as protective factors for the development of Alzheimer’s disease from MCI. The review sheds some suggestions for future research related to the studied topics and for professional intervention in the area of gerontology.
The Treatment of Rheumatic Carditis: A Review and Meta‐Analysis

We performed a meta-analysis of the literature on the treatment of established rheumatic carditis to determine if corticosteroid therapy is superior to salicylates in preventing the sequela of inflammation--valvular damage. We identified 22 reports of comparative trials published since the introduction of corticosteroids in 1949. Five of the 22 studies met the criteria we established for the meta-analysis, which included using randomization and a 1-year follow-up for the presence of a new pathologic apical systolic murmur. Based on the meta-analysis, the advantage of corticosteroid treatment over salicylates in preventing a pathologic murmur at 1 year posttreatment is not statistically significant (estimated odds ratio 0.88; 95% confidence interval: 0.53 to 1.46). However, the meta-analysis is dominated by 1 large negative trial, and there was significant heterogeneity in the results obtained from the studies in the meta-analysis; thus, the question of whether corticosteroid therapy is marginally superior to salicylates for the prevention of valvular heart disease from rheumatic fever remains open.
Cystosarcoma phyllodes. A clinicopathologic study of hypercellular periductal stromal neoplasms of breast

INCE THE ORIGINAL DESCRIPTIONS OF CYSTOS sarcoma phyllodes by Chelius and Miiller, the neoplasm has remained enigmatic. This is in part a consequence of its variable histologic pattern and unpredictable clinical behavior, but is also related to varying interpretations of the term. Johannes Muller, in assigning the designation “cystosarcoma phyllodes,” did not intend to impart a malignant connotation to the lesion. Rather, he implied the combination of a cystic and fleshy tumor and in his original description stated that the condition was perfectly innocent and no more a malignancy than are the condylomata of the genitalia.T Since then the meaning of the term has been modified. In some studies the neoplasm has been defined broadly to include not only large adenofibromas, but also mammary sarcomas.4111 Great size, rapidity of growth and encapsulation are inherent in the designation as it is used by some authors. However, most of the recent studies have restricted the designation to fibroepithelial neoplasms having prominent stromal cellularity, regardless of size or rapidity of gowth. In addition the qualifying adjectives “benign” or “malignant” have been prefixed to the diagnosis. Treves and Sunderland also add a “borderline” group, in which the neoplasm manifests changes short of overt malignancy.l4 As would be expected, this variation in the use of the designation has resulted in considerable inconsistency of findings in reported cases. Some authors intimate that the neoplasm is comparatively benign and can be
Genome-wide analysis of spatiotemporal gene expression patterns during early embryogenesis in rice

Embryogenesis in rice is different from that of most dicotolydonous plants in that it shows a non-stereotypic cell division pattern, formation of dorsal-ventral polarity, and endogenous initiation of the radicle. To reveal the transcriptional features associated with developmental events during rice early embryogenesis, we used microarray analysis coupled with laser microdissection to obtain both spatial and temporal transcription profiles. Our results allowed us to determine spatial expression foci for each expressed gene in the globular embryo, which revealed the importance of phytohormone-related genes and a suite of transcription factors to early embryogenesis. Our analysis showed the polarized expression of a small number of genes along the apical-basal and dorsal-ventral axes in the globular embryo, which tended to fluctuate in later developmental stages. We also analyzed gene expression patterns in the early globular embryo and how this relates to expression in embryonic organs at later stages. We confirmed the accuracy of the expression patterns found by microarray analysis of embryo subdomains using in situ hybridization. Our study identified homologous genes from Arabidopsis thaliana with known functions in embryogenesis in addition to unique and uncharacterized genes that show polarized expression patterns during embryogenesis. The results of this study are presented in a database to provide a framework for spatiotemporal gene expression during rice embryogenesis, to serve as a resource for future functional analysis of genes, and as a basis for comparative studies of plant embryogenesis. Summary: Using laser capture micro-dissection followed by array hybridization, the temporal and spatial gene expression changes occurring during rice embryogenesis are captured.
Parallel Pipeline on Heterogeneous Multi-processing Architectures

We address the problem of providing support for executing single streaming applications implemented as a pipeline of stages that run on heterogeneous chips comprised of several cores and one on-chip GPU. In this paper, we present an API that allows the user to specify the type of parallelism exploited by each pipeline stage running on the CPU multicore, the mapping of the pipeline stages to the devices (GPU or CPU), and the number of active threads. Using as case of study a real streaming application, we evaluate how these parameters affect the performance and energy efficiency of a heterogeneous on-chip processor (Exynos 5 Octa) that has three different computational cores: a GPU, an A15 quad-core and an A7 quad-core. We also explore some memory optimizations and find that while their performance impact depends on the granularity type, they usually reduce energy consumption.
Antecedent conditions to parental monitoring of child internet use

Monitoring and the Internet ii Parental occupational conditions were explored in relation to its ability to predict child Internet monitoring. Utilizing Melvin Kohn's (1977) model of social class and socialization, this study extends Kohn's model as well as provide theoretical groundwork to the area of Internet monitoring. The question of the applicability of Kohn's model to the study of the regulation of Internet access was explored using subsamples from both the Canadian General Social Survey (N = 1142) as well as the American Panel Study of Income Dynamics (N = 1292). Findings showed that Kohn's occupational conditions were not directly predictive of child Internet monitoring behaviors in the parent. Post-hoc analysis examining other variables in the data sets revealed that perhaps an indirect relationship might exist linking occupational conditions and Internet monitoring through a mediating variable of intellectual flexibility. This study concludes with a proposal for a revised model of Kohn's theory that may be better suited to studying Internet monitoring. Monitoring and the Internet iii
Chapter 3 Dynamics of Pattern Motion Computation

U.J. Ilg and G.S. Masson (eds.), Dynamics of Visual Motion Processing: Neuronal, Behavioral, and Computational Approaches, DOI 10.1007/978-1-4419-0781-3_3, © Springer Science+Business Media, LLC 2010 Abstract Early in visual processing neurons with small receptive fields can only signal the component of motion perpendicular to the orientation of the contour that passes through them (the “aperture problem”). A moving visual pattern with differently oriented contours can thus elicit neuronal responses that convey conflicting motion cues. To recover the true direction of motion of such a pattern, later visual areas must integrate the different motion cues over space and time. There is extensive evidence which suggests that this integration is not instantaneous – instead it occurs over time and causes profound changes in the perception of direction of motion of some complex moving patterns. To account for such temporal dynamics, previous studies have focused on a two-pathway model of motion perception: a fast pathway to account for the early percept, and a slow one to account for the late percept. Neurons in macaque area MT are selective for the direction of motion of an object, and their responses appear to be connected directly to the perception of complex motion stimuli in the natural environment. In this chapter, we will discuss neurophysiological data from MT neurons which illustrate how the process of motion perception occurs dynamically. The responses of individual neurons in MT appear to reflect the process by which the primate visual system produces an initial estimate of motion direction and then refines it over time. We will argue that MT neuronal responses are consistent with a single pathway model of motion perception in which temporal dynamics emerge due to two factors: the contrast of elements in the pattern and the time required for the pattern computation.
Reversible Cyclosporin A-sensitive Mitochondrial Depolarization Occurs within Minutes of Stroke Onset in Mouse Somatosensory Cortex in Vivo

Neuronal structure and function are rapidly damaged during global ischemia but can in part recover during reperfusion. Despite apparent recovery in the hours/days following an ischemic episode, delayed cell death can be initiated, making it important to understand how initial ischemic events affect potential mediators of apoptosis. Mitochondrial dysfunction and the opening of the mitochondrial permeability transition pore (mPTP) are proposed to link ischemic ionic imbalance to mitochondrially mediated cell death pathways. Using two-photon microscopy, we monitored mitochondrial transmembrane potential (Δψm) in vivo within the somatosensory cortex during ischemia and reperfusion in a mouse global ischemia model. Our results indicated a synchronous loss of Δψm within 1–3 min of ischemic onset that was linked to within seconds of plasma membrane potential (Δψp) depolarization. Δψm recovered rapidly upon reperfusion, and no delayed depolarization was observed over 2 h. Cyclosporin A treatment largely blocked Δψm collapse during ischemia, suggesting a role for the mPTP. Blocking Δψm depolarization did not affect structural damage to dendrites, indicating that the opening of the mPTP and damage to dendrites are separable pathways that are activated during Δψp depolarization. Our findings using in vivo imaging suggest that mitochondrial dysfunction and specifically the activation of the mPTP are early reversible events during brain ischemia that could trigger delayed cell death.
Fatal motor vehicle crashes in Texas: needs for and access to emergency medical services

ABSTRACT Access to emergency medical services (EMS) was examined for fatal motor vehicle crashes (MVCs) in Texas. Actual needs for EMS were assessed using MVC fatality distribution; revealed EMS accessibility was evaluated using EMS utilization records. Total prehospital time records the time between a MVC occurrence and a victim’s arrival at hospital; it includes activation time, ambulance response time and hospital transport time. The revealed accessibility was compared to potential accessibility, which is based on assumed transportation time to trauma designated hospitals. It was found that although fatal MVCs were more concentrated in urban areas, the fatality rate was higher in rural Texas. The total prehospital time and the component time segments were longer in rural areas, confirming poor EMS access for rural Texas. Significant difference exists for EMS accessibility across the eight state-level health service regions. The study also points to a possible threshold distance or transport time, beyond which the actual access to EMS is poorer than would be expected.
