Burnout of the Mind – Burnout of the Body?

In the present paper we investigate whether patients with a clinical diagnosis of burnout show physiological signs of burden across multiple physiological systems referred to as allostatic load (AL). Measures of the sympathetic-adrenergic-medullary (SAM) axis and the hypothalamic-pituitary-adrenal (HPA) axis were assessed. We examined patients who had been diagnosed with burnout by their physicians (n = 32) and were also identified as burnout patients based on their score in the Maslach Burnout Inventory-General Survey (MBI-GS) and compared them with a nonclinical control group (n = 19) with regard to indicators of allostatic load (i.e., ambulatory ECG, nocturnal urinary catecholamines, salivary morning cortisol secretion, blood pressure, and waist-to-hip ratio [WHR]). Contrary to expectations, a higher AL index suggesting elevated load in several of the parameters of the HPA and SAM axes was found in the control group but not in the burnout group. The control group showed higher norepinephrine values, higher blood pressure, higher WHR, higher sympathovagal balance, and lower percentage of cortisol increase within the first hour after awakening as compared to the patient group. Burnout was not associated with AL. Results seem to indicate a discrepancy between self-reported burnout symptoms and psychobiological load.
The Dependence in the Equations of Motion

A spindle headstock of a multiple-operation machine tool, whose housing accommodates, in a coaxial and rotatable arrangement, a spindle kinematically coupled to a rotary drive, a tie rod carrying members intended for connection to the shank of a boring head having a swivel carriage, which tie rod is axially adjustable in relation to the spindle, and a bar carrying toothed members for meshing with toothed members mounted on an end of a slide bar whose opposite end serves for radial displacement of the carriage. The bar is kinematically coupled to a drive whereby it is displaced in the axial direction in relation to the spindle. The members of the tie rod, which serve for connection to the shank of the boring head, are mounted on the tie rod so that they can radially reciprocate during location of the tie rod. For radial adjustment of the bar, a bushing is provided on the tie rod, which is axially stationary in relation to the tie rod and kinematically coupled to the spindle and bar.
Determination of green phytomass in a northern boreal forest by means of Landsat TM-data and a forest canopy reflectance model

The aim of this paper is to investigate the feasibility of using remotely sensed data for the determination of important biophysical parameters relevant to carbon modelling in northern boreal forests. Detailed ground and remotely sensed data (Landsat TM) have been collected in a forest area in Siggefora, central Sweden, dominated by Norway spruce and Scots pine. A forest canopy reflectance model has been used to model stand reflectances. Estimates of reflectances obtained from the model have been compared with reflectances measured in Landsat TM-data. The sensitivity of the model to different parameters has been analysed. Results of the study show that differences in satellite derived stand reflectances can be partly explained with a canopy reflectance model. The sensitivity analysis shows that conifer stand reflectance is influenced by the structural features rather than the leaf area index of the stand.
Generalized Hadamard Product and the Derivatives of Spectral Functions

Real valued functions, $F(X)$, on a symmetric matrix argument are called spectral if $F(U^TXU) = F(X)$ for every orthogonal matrix $U$ and $X \in \mathrm{dom\,} F$. We are interested in a description of the higher order derivatives (when they exist) of $F$ with respect to $X$. Formulae for the gradient and the Hessian of $F$ are given in [A. S. Lewis, Math. Oper. Res., 21 (1996), pp. 576-588] and [A. S. Lewis and H. S. Sendov, SIAM Matrix Anal. Appl. , 23 (2001), pp. 368-386]. In this work we present common features of these two formulae that are preserved in the higher order derivatives.
Adaptive routing and wavelength assignment in GMPLS controlled optical networks using ant colony optimization

In this paper, we present an adaptive routing and wavelength assignment algorithm based on the ant colony optimization meta-heuristics. We propose a modification on the routing part of a previously published ant-based algorithm to enhance the performance in terms of blocking probability. In addition, we propose two new approaches for the wavelength assignment part: most-used and least-used. These two new approaches can be implemented by the deployment of a new structure at the optical nodes and by the straightforward collecting of wavelength usage in the links traversed by the ants.
Adaptive control of an inductive power transfer coupling for servomechanical systems

This paper presents adaptive-control schemes that estimate load-model parameters and adaptively "tune" a digital controller for an inductively-coupled power delivery circuit. Estimation algorithms are presented that utilize specific recursive formulations, which provide adequate noise immunity in a power-electronic environment. The techniques are demonstrated using a servomechanical system and a 1.5 kW prototype power electronic drive.
Prevalence of External Injuries in Small Cetaceans in Aruban Waters, Southern Caribbean

Aruba, located close to the coasts of Colombia and Venezuela, is one of the most densely populated islands in the Caribbean and supports a wide range of marine-related socio-economic activities. However, little is known about the impacts of human activities on the marine environment. Injuries in marine mammals can be used to examine interactions with human activities and identify potential threats to the survival of populations. The prevalence of external injuries and tooth rake marks were examined in Atlantic spotted dolphin (Stenella frontalis) (n = 179), bottlenose dolphin (Tursiops truncatus) (n = 76) and false killer whale (Pseudorca crassidens) (n = 71) in Aruban waters using photo identification techniques. Eleven injury categories were defined and linked to either human-related activities or natural causes. All injury categories were observed. In total, 18.7% of all individuals had at least one injury. Almost half (41.7%) of the injuries could be attributed to human interactions, of which fishing gear was the most common cause (53.3%) followed by propeller hits (13.3%). Major disfigurements were observed in all three species and could be attributed to interactions with fishing gear. The results of this study indicate that fishing gear and propeller hits may pose threats to small and medium-sized cetaceans in Aruban waters. Thus, long-term monitoring of population trends is warranted. Shark-inflicted bite wounds were observed in Atlantic spotted dolphin and bottlenose dolphin. Bite wounds of cookie cutter sharks (Isistius sp.) were recorded in all three species, and include the first documented record of a cookie cutter shark bite in Atlantic spotted dolphin. This is one of the few studies which investigates the prevalence of injuries in cetaceans in the Caribbean. Further study is necessary to determine to which extent the injuries observed in Aruba affect the health and survival of local populations.
Area and Power Efficient Modulo 2^n+1 Multiplier

: In this paper area-power efficient modulo 2 n +1 multiplier is proposed. The result and one operand for the new modulo multipliers use weighted representation, while the other uses the diminished-1. By using the radix-4 Booth recoding, the new multipliers reduce the number of the partial products to n/2 for even and (n+1)/2 for odd except for one correction term. According to our algorithm, the resulting partial products are added through inverted end around carry save adder into two operands, which are finally adder by a 2-stage n-bit adder containing 2:1 multiplexer. By using the purposed adder, the new multipliers reduce the area and power. The analytical and experimental result indicates that the new modulo 2 n +1 multipliers, offer reduced power and more compact area among all the existing structures.

Analysis of the correlation properties of QOCCC

Complete complementary codes attract the attention of researchers thanks to their unique ideal correlation properties. Still, the boarder on maximum number of signatures is limiting. Quasi orthogonal complete complementary codes allow higher maximum number of signatures in exchange for a slight loss of some ideality of correlation properties. This article focuses on the analysis of these codes and identifies the shifts of broken ideal correlation properties as these vary for different element dimensions.
Knowledge Discovery from Online Communities

During recent years, the outstanding growth of social network communities has caught the attention of the research community. A huge amount of user-generated content is shared among community users and gives researchers the unique opportunity to thoroughly investigate social community behavior. Many studies have been focused on both developing models to investigate user and collective behavior and building applications tailored to the most common community user activities. This chapter presents an overview of social network features such as user behavior, social models, and user-generated content to highlight the most notable research trends and application systems built over such appealing models and online media data. It first describes the most popular social networks by analyzing the growth trend, the user behaviors, the evolution of social groups and models, and the most relevant types of data continuously generated and updated by the users. Next, the most recent and valuable applications of data mining techniques to social network models and user-generated content are presented. Discussed works address both social model extractions tailored to semantic knowledge inference and automatic understanding of the user-generated content. Finally, prospects of data mining research on social networks are provided as well. DOI: 10.4018/978-1-4666-2455-9.ch063
Statistical Significance Analysis of the R-DPSO Towards an Understanding of the Relationship Between the Population of Robots and the Maximum Communication Distance

This paper presents a statistical significance analysis of a modified version of the Particle Swarm Optimization (PSO) on groups of simulated robots performing a distributed exploration task, denoted as R-DPSO (Robotic DPSO). This work aims to evaluate this novel exploration strategy studying the performance of the algorithm under communication constraints while increasing the population of robots. Experimental results show that there is no linear relationship between the number of robots and the maximum communication range. In general, the decreased performance by the developed algorithm under communication constraints can be overcome by slightly increasing the number of robots as the maximum communication range is decreased.
How animals contribute to subjective well-being: A comprehensive model of protective and risk factors

Abstract In this paper, we elaborate and test a comprehensive theoretical model of SWB of animal caregivers. This model includes risk factors such as restrictions in daily life, negative emotions, and financial strain, and protective factors such as a sense of purpose in life, positive emotions, and physical activities. The model was tested in a sample of caregivers of dogs, cats, and horses (N = 631). Higher levels of satisfaction of the need for autonomy, experiencing more positive emotions, and greater fulfillment of social roles through the animal were positively associated with SWB, whereas experiencing more negative emotions, greater financial strain due to the animal, and degree of attachment to the animal were negatively associated with SWB. The proposed model is suitable to explain differences in subjective well-being among animal caregivers and may be valid across different types of animal caregivers.
Asymptotic Imaging of Perfectly Conducting Cracks

In this paper, we consider cracks with Dirichlet boundary conditions. We first derive an asymptotic expansion of the boundary perturbations that are due to the presence of a small crack. Based on this formula, we design a noniterative approach for locating a collection of small cracks. In order to do so, we construct a response matrix from the boundary measurements. The location and the length of the crack are estimated, respectively, from the projection onto the noise space and the first significant singular value of the response matrix. Indeed, the direction of the crack is estimated from the second singular vector. We then consider an extended crack with Dirichlet boundary conditions. We rigorously derive an asymptotic expansion for the boundary perturbations that are due to a shape deformation of the crack. To reconstruct an extended crack from many boundary measurements, we develop two methods for obtaining a good guess. Several numerical experiments show how the proposed techniques for imaging small cracks as well as those for obtaining good initial guesses toward reconstructing an extended crack behave.
Phosphomannosyl-derivatized beads detect a receptor involved in lymphocyte homing

Recirculating lymphocytes initiate extravasation from the blood stream by binding to specialized high endothelial venules (HEV) within peripheral lymph nodes (PN) and other secondary lymphoid organs. We have previously reported that lymphocyte attachment to PN HEV is selectively inhibited by mannose-6-phosphate (M6P) and related carbohydrates (Stoolman, L. M., T. S. Tenforde, and S. D. Rosen, 1984, J. Cell Biol., 99:1535-1540). In the present study, we employ a novel cell-surface probe consisting of fluorescent beads derivatized with PPME, a M6P-rich polysaccharide. PPME beads directly identify a carbohydrate-binding receptor on the surface of mouse lymphocytes. In every way examined, lymphocyte attachment to PPME beads (measured by flow cytofluorometry) mimics the interaction of lymphocytes with PN HEV (measured in the Stamper-Woodruff in vitro assay): both interactions are selectively inhibited by the same panel of structurally related carbohydrates, are calcium-dependent, and are sensitive to mild treatment of the lymphocytes with trypsin. In addition, thymocytes and a thymic lymphoma, S49, bind poorly to PPME beads in correspondence to their weak ability to bind to HEV. When the S49 cell line was subjected to a selection procedure with PPME beads, the ability of the cells to bind PPME beads, as well as their ability to bind to PN HEV, increased six- to eightfold. We conclude that a carbohydrate-binding receptor on mouse lymphocytes, detected by PPME beads, is involved in lymphocyte attachment to PN HEV.

The experience and meaning of compassion and self-compassion for individuals with depression or anxiety.

OBJECTIVES The objective of this study was to explore the meaning and experiences of compassion and self-compassion for individuals with depression and anxiety. DESIGN An interpretative phenomenological analysis (IPA) epistemology and methodology were adopted as the study was focused on understanding the meaning and experiences of participants towards self-compassion from existing theory. METHODS Ten participants were selected based on a Diagnostic and Statistical Manual of Mental Disorders, 4th Ed.-text revision diagnosis of depression or an anxiety disorder. Individuals were excluded from this study if they had additional diagnoses which impacted significantly on their disorder or on ethical grounds if participation was seen as psychologically distressing. Participants completed a semi-structured interview with questions were based on existing self-compassion research. Interviews lasted an hour and were analysed using IPA methodology. RESULTS Participants' reflections suggested that they saw compassion having two central qualities: kindness and action. Participants reported that they thought having compassion for themselves felt meaningful in relation to their experiences and useful in helping with their depression or anxiety. However, participants reflected that they felt being self-compassionate would be difficult either because the concept itself felt challenging to enact or their experience of psychological disorder had negatively impacted on their ability to be self-compassionate. CONCLUSIONS Participants' positive perceptions of self-compassion offer encouragement to clinicians as it appears people can connect with the concept meaningfully as well as seeing it as being useful. Clinicians focusing on self-compassion may gain greater efficacy when they incorporate both aspects within interventions. Findings about the difficulties associated with self-compassion provide valuable information as to why people find it difficult to adopt which can be used in the development of future clinical interventions.
Electron transport in strained Si inversion layers grown on SiGe-on-insulator substrates

We show by simulation that electron mobility and velocity overshoot are greater when strained inversion layers are grown on SiGe-On-insulator substrates (strained Si/SiGe-OI) than when unstrained silicon-on-insulator (SOI) devices are employed. In addition, mobility in these strained inversion layers is only slightly degraded compared with strained bulk Si/SiGe inversion layers, due to the phonon scattering increase produced by greater carrier confinement. Poisson and Schroedinger equations are self-consistently solved to evaluate the carrier distribution in this structure. A Monte Carlo simulator is used to solve the Boltzmann transport equation. Electron mobility in these devices is compared to that in SOI inversion layers and in bulk Si/SiGe inversion layers. The effect of the germanium mole fraction x, the strained-silicon layer thickness, TSi, and the total width of semiconductor (Si+SiGe) slab sandwiched between the two oxide layers, Tw were carefully analyzed. We observed strong dependence of the e.
Developing a Theory of Knowledge Management Across Projects

This paper contributes a conceptual for defining knowledge management in a project environment. Knowledge management can be broadly defined as the set of processes, tools, and techniques for the most effective and efficient use of knowledge [1]. Knowledge management aims to improve, maintain, and create organizational capabilities to generate sustained competitive advantage [2]. A holistic view of knowledge management across project teams is described. A model of the causal relationship among the elements of the model is proposed. This investigation serves as foundation for further research and development in the effort to define the appropriate set of managerial actions required for successful knowledge management across projects.
A two-arm situated artificial communicator for human-robot cooperative assembly

We present the development of a robot system with some cognitive capabilities, as well as experimental results. We focus on two topics: assembly by two hands and understanding human instructions in nonconstrained natural language. These two features distinguish human beings from animals, and are, thus, the means leading to high-level intelligence. A typical application of such a system is a human-robot cooperative assembly. A human communicator sharing a view of the assembly scenario with the robot instructs the latter by speaking to it in the same way that he would communicate with a child whose common-sense knowledge is limited. His instructions can be underspecified, incomplete, and/or context dependent. After introducing the general purpose of our research project, we present the hardware and software components of our robots needed for interactive assembly tasks. We then discuss the control architecture of the robot system with two stationary robot arms by describing the functionalities of perception, instruction understanding, and execution. To show how our robot learns from humans, the implementations of a layered learning methodology, memory, and monitoring functions are introduced. Finally, we outline a list of future research topics related to the enhancement of such systems.

The determinants of job stress that have been examined under this study include, management role, relationship with others, workload pressure, homework interface, role ambiguity, and performance pressure. The sample consists of a public university academician from Klang Valley area in Malaysia. The results show there is a significant relationship between four of the constructs tested. The results also show that there is significant negative relationship between job stress and job satisfaction.
Order to Avoid Inter-Vector-Conflicts in Complex Memory System

The performance of a vector processor accessing vectors is strongly dependent on the conflicts produced in the memory subsystem. These conflicts delay the work of the functional units. The concurrent memory access of several vector streams causes inter-conflicts between the references of the different vector streams. In a memory system where several memory modules are mapped in every bus (complex memory system) the number of conflicts increases because the bus must be shared by vector streams. Conflicts named linked conflicts and complex conflicts decrease the performance of the steady-state phase in complex memory systems (CRAY X-MP). This paper proposes a method that allows a concurrent access to several vector streams reducing the average memory access time in vector processors with complex memory systems.
More on the tensorial central charges in N=1 supersymmetric gauge theories: BPS wall junctions and strings

We study the central extensions of the N=1 superalgebras relevant to the soliton solutions with the axial geometry--strings, wall junctions, etc. A general expression valid in any four-dimensional gauge theory is obtained. We prove that the only gauge theory admitting BPS strings at weak coupling is supersymmetric electrodynamics with the Fayet-Iliopoulos term. The problem of the ambiguity of the (1/2,1/2) central charge in the generalized Wess-Zumino models and gauge theories with matter is addressed and solved. A possibility of existence of the BPS strings at strong coupling in N=2 theories is discussed. A representation of different strings within the brane picture is presented.
