Shame in the therapy hour

Excessive shame can be associated with poor psychological adjustment, interpersonal difficulties, and overall poor life functioning. Consequently, shame is prevalent among individuals undergoing psychotherapy. Yet, there is limited guidance for clinicians trying to help their clients deal with shame-related concerns. This book explores the manifestations of shame and presents several approaches for treatment. It brings together the insights of master clinicians from different theoretical and practice orientations, such as psychodynamics, object relations, emotion-focused therapy, functional analysis, group therapy, family therapy, and couples therapy. The chapters address all aspects of shame, including how it develops, how it relates to psychological difficulties, how to recognize it, and how to help clients resolve it. Strategies for dealing with therapist shame are also provided, since therapist shame can be triggered during sessions and can complicate the therapeutic alliance. With rich, detailed case studies in almost every chapter, this book will be a practical resource for clinicians working with a broad range of populations and clinical problems.
On Elastic Block Ciphers and Their Differential and Linear Cryptanalyses

Motivated by applications such as databases with nonuniform field lengths, we introduce the concept of an elastic block cipher, a new approach to variable length block ciphers which incorporates fixed sized cipher components into a new network structure. Our scheme allows us to dynamically “stretch” the supported block size of a block cipher up to a length double the original block size, while increasing the computational workload proportionally to the block size. We show that traditional attacks against an elastic block cipher are impractical if the original cipher is secure. In this paper we focus on differential and linear attacks. Specifically, we employ an elastic version of Rijndael supporting block sizes of 128 to 256 bits as an example, and show it is resistant to both differential and linear attacks. In particular, employing a different method than what is employed in Rijndael design, we show that the probability of any differential characteristic for the elastic version of Rijndael is ≤ 2. We further prove that both linear and nonlinear attacks are computationally infeasible for any elastic block cipher if the original cipher is not subject to such an attack and involves a block size for which an exhaustive plaintext search is computationally infeasible (as is the case for Rijndael).
Local visual words coding for low bit rate mobile visual search

Mobile visual search has attracted extensive attention for its huge potential for numerous applications. Research on this topic has been focused on two schemes: sending query images, and sending compact descriptors extracted on mobile phones. The first scheme requires about 30-40KB data to transmit, while the second can reduce the bit rate by 10 times. In this paper, we propose a third scheme for extremely low bit rate mobile visual search, which sends compressed visual words consisting of vocabulary tree histogram and descriptor orientations rather than descriptors. This scheme can further reduce the bit rate with few extra computational costs on the client. Specifically, we store a vocabulary tree and extract visual descriptors on the mobile client. A light-weight pre-retrieval is performed to obtain the visited leaf nodes in the vocabulary tree. The orientation of each local descriptor and the tree histogram are then encoded to be transmitted to server. Our new scheme transmits less than 1KB data, which reduces the bit rate in the second scheme by 3 times, and obtains about 30% improvement in terms of search accuracy over the traditional Bag-of-Words baseline. The time cost is only 1.5 secs on the client and 240 msecs on the server.
Options for ground fault clearance in HVDC offshore networks

The unavailability of adequate HVDC circuit breakers is often named as one of the key inhibitors for building HVDC multi-terminal networks. Instead of only discussing what needs to be done with respect to improving CB technology, we discuss what other options in principle exist. None of the options is optimum in itself, thus the discussion must be mainly driven by reviewing the pros and cons from a fault current clearing point of view and also from a network planning and operation point of view. The manuscript aims at triggering and stimulating the discussion on fault clearance options other than only CBs.
Proto-Oncogene Raf-1 as an Autoantigen in Meniere's Disease

The 28 kd protein extracted from the guinea pig inner ear membranous fraction, which reacted with sera from patients with Meniere's disease, has been subjected to microsequencing. Nineteen amino acids were obtained (IVQQFGFQRRASDDGKLTQ). A protein data bank search showed that this sequence corresponded to residues 41 to 60 of human Raf-1 protein. Sera from 16 of 27 patients with Meniere's disease showed reactivity to the recombinant purified glutathione-S-transferase–Raf-1 protein. These results support the hypothesis that a subgroup of patients who suffer from Meniere's disease, as well as some other kinds of autoimmune inner ear diseases, have an autoantibody against Raf-1 protein.
Blind CFO Estimation for Noncritically Sampled FMT Systems

In this correspondence, we consider the problem of blind carrier-frequency offset (CFO) estimation for noncritically sampled filtered multitone (FMT) systems. Specifically, a closed-form CFO estimator, based on the best linear unbiased (BLU) estimation principle, is derived. Although the proposed BLU estimator is derived under the hypothesis of additive white Gaussian noise channel, it demonstrates a remarkable robustness against multipath fading. Moreover, it does not require the knowledge of the symbol timing. The performance of the derived BLU estimator is compared with that of four recently proposed CFO estimators for FMT systems.
Timing Analysis of Fixed Priority Self-Suspending Sporadic Tasks

Many real-time systems include tasks that need to suspend their execution in order to externalize some of their operations or to wait for data, events or shared resources. Although commonly encountered in real-world systems, study of their timing analysis is still limited due to the problem complexity. In this paper, we invalidate a claim made in one of the earlier works [1], that led to the common belief that the timing analysis of one self-suspending task interacting with non-self suspending sporadic tasks is much easier than in the periodic case. This work highlights the complexity of the problem and presents a method to compute the exact worst-case response time (WCRT) of a self-suspending task with one suspension region. However, as the complexity of the analysis might rapidly grow with the number of tasks, we also define an optimization formulation to compute an upper-bound on the WCRT for tasks with multiple suspension regions. In the experiments, our optimization framework outperforms all previous analysis techniques and often finds the exact WCRT.
Phenotypic alterations of neurons that innervate osteoarthritic joints in rats.

OBJECTIVE Pain is a prominent feature of osteoarthritis (OA). To further understand the primary mechanisms of nociception in OA, we studied the expression of the phenotype markers calcitonin gene-related peptide (CGRP), isolectin B4 (IB4), and neurofilament 200 (NF200) in sensory neurons innervating the OA knee joint in rats. METHODS OA was induced in rats by intraarticular injection of 2 mg of mono-iodoacetate (MIA) into the knee. Neurons innervating the joint were identified by retrograde labeling with fluorogold in dorsal root ganglia (DRG) and colocalized with neurochemical markers by immunofluorescence. The total number of DRG cells was determined by stereologic methods in Nissl-stained sections. RESULTS A 37% decrease in the number of fluorogold-backlabeled cells was observed in rats with OA when compared with control rats, even though no decrease in the total number of cells was observed. However, an increase in the number of medium/large cell bodies and a decrease in the number of the smallest cells were observed, suggesting the occurrence of perikarya hypertrophy. The percentage of CGRP-positive cells increased significantly, predominantly in medium/large cells, suggesting the occurrence of a phenotypic switch. Colocalization of CGRP and NF200 revealed no significant changes in the percentage of double-labeled cells, but an increase in the number of medium/large double-labeled cells was observed. No differences in the expression of either IB4 or NF200 were observed in fluorogold-backlabeled cells. CONCLUSION These results indicate that MIA-induced OA causes an up-regulation of CGRP in different subpopulations of primary afferent neurons in DRG due to a phenotypic switch and/or cell hypertrophy which may be functionally relevant in terms of the onset of pain in this pathologic condition.
LUNG HYPERINFLATION IN COPD : What the Clinician Needs to Know

Lung hyperinflation, chronic dyspnea and reduced exercise capacity are inextricably linked and are independent predictors of increased mortality in COPD. It is no surprise, therefore, that a major goal of management is to reduce lung hyperinflation in the hope of improving dyspnea, exercise tolerance and related long term patientcentered outcomes. The negative effects of lung hyperinflation on respiratory muscle and cardio-circulatory function are now well established and the negative effects of acute dynamic hyperinflation during exacerbations and physical activity are increasingly recognized. Additional evidence of the importance of lung hyperinflation comes from multiple studies which have examined the clinical benefits of therapeutic interventions that reduce the effect of lung hyperinflation. The current review summarizes the causes and clinical consequences of lung hyperinflation and provides a strong rationale for its therapeutic reversal.
One Scan is Enough: Optimising Association Rules Mining

Data mining is as a new area of research has taken its place as one of the most important techniques in the decision making process. Mining association rules is one of simple yet powerful technique in the data mining process The problem of mining association rules is composed of finding the large itemsets and to generate the association rules from these itemsets. Usually the dataset must be scanned many times in order to find the large itemsets. Many algorithms have been developed to increase the performance of mining association rules through reducing the number of scans over the dataset. This work aims to enhance and optimise the process even further by developing techniques to reduce the number of database scans to just only one. Keywords: Data mining, Association
Non-invasive green small cell network

Future low cost wireless networks are expected to provide high data rates with low power consumption. A dense deployment of distributed small-cells, within the existing network infrastructure, is one of the candidate solutions to achieve this goal. Unfortunately, the aggregate signal resulting from the transmission of these multiples small cells can be considered as an electromagnetic (EM) pollution for passive users who do not carry wireless devices. These users are victim of primary electromagnetic “smokers” and request from operators to be spared from these new base stations. The aim of this contribution is to propose an electromagnetic friendly environment with minimum EM pollution, while satisfying the quality of service requirements. The technique employed, called Distributed Space-Time Reversal (DSTR), focuses the energy on active users (equipped with wireless devices) and is able to spare passive users from EM waves. In this contribution, we provide a theoretical analysis of the technique and show the impact of active/passive users with respect to the number of cells.
Are cuts to health expenditure in Victoria compromising quality of care?

Separate state‐wide surveys of women who had recently given birth in Victoria were conducted in 1989 and 1993. The first survey was conducted in conjunction with the Victorian Ministerial Review of Birthing Services. The second survey occurred three years after the release of the Review's final report and three months after the introduction of casemix funding. It coincided with a period of substantial cutbacks to expenditure on Victorian public hospitals. In both studies, surveys were mailed to women 6 to 9 months after the birth. Response rates were 71.4% (n=790) in 1989 and 62.5% (n=1336) in 1993. Between the two surveys, the proportion of women giving critical feedback about caregivers, more than doubled. The survey findings suggest that standards of care are being compromised in the current economic and policy environment.
GB-MAC: a backbone based low latency protocol for WSNs

This paper presents GB-MAC, an asynchronous cross-layer medium access control protocol. Several MAC protocols suffer from the sleep-delay problem which causes a large latency in multi-hop communications. In our approach, we create a backbone composed by nodes with short active-sleep cycles to ensure a fast multi-hop relay of messages from and to the sink node. About 15% of nodes are recruited to form the backbone. Moreover, our protocol is asynchronous in order to avoid the complexity arising from constant time synchronizations. Simulations have shown that our protocol presents a low latency in all scenarios, outperforming X-MAC up to a factor of ten. The energy consumption is also reduced for moderate traffic scenarios. The GB-MAC yields higher gains in large scenarios, hence our results evidence that it is a robust protocol to be employed in large sensor networks.
La gouvernance etat des lieux et controverses conceptuelles (State of the art and conceptual contreverses)

La diversite des connotations attachees a la notion (ou aux notions) de gouvernance ne pouvait manquer de susciter l’appetit des chercheurs desireux de renouveler leurs outils d’analyse face a un monde en mutation acceleree (mondialisation, dereglementation, rapports entre puissances, decentralisation, …). La gouvernance est une notion qui a pris en deux decennies une importance considerable et fait flores dans les discours politiques et scientifiques. Ce document fait l’etat des lieux sur les differentes approches et theories faites de ce concept, sous ses multiples domaines et disciplines d’application et depuis divers lieux. Si la notion de gouvernance prouve d’indeniables qualites strategiques et politiques, son usage sans precaution dans l’analyse scientifique peut se reveler perilleux. For several years, Governance has become a concept arousing the interest of economists and of the political community. Since twenty years, it has taken a major importance and it is at the center of political and scientific speeches. In a changing world, researchers have to renew their analysis tools on this topic (globalization, deregulation, decentralization, etc). This document focuses on the approaches and theories of governence. The concept of governance presents strategic and political qualities, but its use without precaution in the scientific analysis may be perilous.
Are you talking to me? : The nature of community in entrepreneurship scholarship

Research in entrepreneurship has grown rapidly, encompassing multiple theoretical and methodological traditions. This special issue is devoted to understanding the scientific structure of entrepreneurship research. Articles included in this issue use bibliometric techniques to find linkages within published entrepreneurship scholars. These analyses compellingly show that: research in our field contains: multiple but disconnected research themes; dominant research themes reflecting the disciplinary training and lens of authors; very few papers get cited even in our disciplinary journals; and key research themes and foci are subject to considerable dynamism and change. The articles provide rich opportunities for insightful, influential and creative research in the field.
Leptin in the regulation of immunity, inflammation, and hematopoiesis

Leptin, the product of the ob gene, is a pleiotropic molecule that regulates food intake as well as metabolic and endocrine functions. Leptin also plays a regulatory role in immunity, inflammation, and hematopoiesis. Alterations in immune and inflammatory responses are present in leptin‐ or leptin‐receptor‐deficient animals, as well as during starvation and malnutrition, two conditions characterized by low levels of circulating leptin. Both leptin and its receptor share structural and functional similarities with the interleukin‐6 family of cytokines. Leptin exerts proliferative and anti‐apoptotic activities in a variety of cell types, including T lymphocytes, leukemia cells, and hematopoietic progenitors. Leptin also affects cytokine production, the activation of monocytes/macrophages, wound healing, angiogenesis, and hematopoiesis. Moreover, leptin production is acutely increased during infection and inflammation. This review focuses on the role of leptin in the modulation of the innate immune response, inflammation, and hematopoiesis.
Channel capacity with channel interference in MIMO-WLAN systems

The channel capacity of multiple-input multiple-output (MIMO) wireless local area network (MIMO-WLAN) systems with co-channel interference (CCI) is calculated in this paper. The ability to combat CCI for the MIMO-WLAN simple uniform linear array (ULA) and polarization diversity array (PDA) are investigated. The channel frequency response, which is further used to calculate the corresponding channel capacity is calculated by ray-tracing approach. Numerical results show that MIMO-PDA is better than those of MIMO-ULA when interference is present.
Optimal Stopping and the American Put

We show that the problem of pricing the American put is equivalent to solving an optimal stopping problem. the optimal stopping problem gives rise to a parabolic free-boundary problem. We show there is a unique solution to this problem which has a lower boundary. We identify an integral equation solved by the boundary and show that it is the unique solution to this equation satisfying certain natural additional conditions. the proofs also give a natural decomposition of the price of the American option as the sum of the price of the European option and an "American premium.

Potential Role of Epigenetic Mechanism in Manganese Induced Neurotoxicity

Manganese is a vital nutrient and is maintained at an optimal level (2.5–5 mg/day) in human body. Chronic exposure to manganese is associated with neurotoxicity and correlated with the development of various neurological disorders such as Parkinson's disease. Oxidative stress mediated apoptotic cell death has been well established mechanism in manganese induced toxicity. Oxidative stress has a potential to alter the epigenetic mechanism of gene regulation. Epigenetic insight of manganese neurotoxicity in context of its correlation with the development of parkinsonism is poorly understood. Parkinson's disease is characterized by the α-synuclein aggregation in the form of Lewy bodies in neuronal cells. Recent findings illustrate that manganese can cause overexpression of α-synuclein. α-Synuclein acts epigenetically via interaction with histone proteins in regulating apoptosis. α-Synuclein also causes global DNA hypomethylation through sequestration of DNA methyltransferase in cytoplasm. An individual genetic difference may also have an influence on epigenetic susceptibility to manganese neurotoxicity and the development of Parkinson's disease. This review presents the current state of findings in relation to role of epigenetic mechanism in manganese induced neurotoxicity, with a special emphasis on the development of Parkinson's disease.
Interspecific Nematode Signals Regulate Dispersal Behavior

Background Dispersal is an important nematode behavior. Upon crowding or food depletion, the free living bacteriovorus nematode Caenorhabditis elegans produces stress resistant dispersal larvae, called dauer, which are analogous to second stage juveniles (J2) of plant parasitic Meloidogyne spp. and infective juveniles (IJ)s of entomopathogenic nematodes (EPN), e.g., Steinernema feltiae. Regulation of dispersal behavior has not been thoroughly investigated for C. elegans or any other nematode species. Based on the fact that ascarosides regulate entry in dauer stage as well as multiple behaviors in C. elegans adults including mating, avoidance and aggregation, we hypothesized that ascarosides might also be involved in regulation of dispersal behavior in C. elegans and for other nematodes such as IJ of phylogenetically related EPNs. Methodology/Principal Findings Liquid chromatography-mass spectrometry analysis of C. elegans dauer conditioned media, which shows strong dispersing activity, revealed four known ascarosides (ascr#2, ascr#3, ascr#8, icas#9). A synthetic blend of these ascarosides at physiologically relevant concentrations dispersed C. elegans dauer in the presence of food and also caused dispersion of IJs of S. feltiae and J2s of plant parasitic Meloidogyne spp. Assay guided fractionation revealed structural analogs as major active components of the S. feltiae (ascr#9) and C. elegans (ascr#2) dispersal blends. Further analysis revealed ascr#9 in all Steinernema spp. and Heterorhabditis spp. infected insect host cadavers. Conclusions/Significance Ascaroside blends represent evolutionarily conserved, fundamentally important communication systems for nematodes from diverse habitats, and thus may provide sustainable means for control of parasitic nematodes.
The effects of glucocorticoids on red and white muscles in the rat.

The association of muscle weakness with glucocorticoid excess has often been observed clinically. "A Light microscopic study of biopsy specimens from patients given such steroids and exhibiting weakness, however, has not always revealed pathologic change which could account for the weakness observed. ' 3'5 With the electron microscope, a variety of mitochondrial alterations have been observed in cases of steroid myopathy.6 7 These have included unusually large mitochondria, mitochondrial aggregates, mitochondrial vacuolation, regions of mitochondrial disappearance, as well as areas of myofilament loss. No consistent pattern of ultrastructural change has been identified, however, and the evolution of the lesions has remained obscure. In experimental studies, Ellis8 reported widespread muscle necrosis in the rabbit after administration of large doses of cortisone. Smith,9 using histochemical methods, reported predominant involvement of white muscle fibers in myopathies induced in rabbit muscle by triamcinolone administration. In contrast, in a combined light and electron microscopic study, D'Agostino and Chiga'0 reported that red fibers in the rabbit diaphragm were most strikingly affected by cortisone administration. The questions asked in this study were whether fine structural changes could be produced in rat muscle by the administration of glucocorticoid hormones, and, if so, whether these changes could be related to those observed in human steroid myopathy. The soleus, a red muscle, and the medial head of the gastrocnemius, a white muscle, were selected for study. These muscles contain relatively homogeneous populations of red and white fibers respectively, and changes in their mitochondrial content may be more easily evaluated. In addition, because of the different functional demands on these muscles and their different fine structure, it was of interest to see if they would respond differently to pathogenic stimuli.
