Personal relatedness and attachment in infants of mothers with borderline personality disorder

The principal aim of this study was to assess personal relatedness and attachment patterns in 12-month-old infants of mothers with borderline personality disorder (BPD). We also evaluated maternal intrusive insensitivity toward the infants in semistructured play. We videotaped 10 mother–infant dyads with borderline mothers and 22 dyads where the mothers were free from psychopathology, in three different settings: a modification of Winnicott's Set Situation in which infants faced an initially unresponsive (“still-face”) stranger, who subsequently tried to engage the infant in a game of give and take; the Strange Situation of Ainsworth and Wittig; and a situation in which mothers were requested to teach their infants to play with miniature figures and a toy train. In relation to a set of a priori predictions, the results revealed significant group differences as follows: (a) compared with control infants, toward the stranger the infants of mothers with BPD showed lower levels of “availability for positive engagement,” lower ratings of “behavior organization and mood state,” and a lower proportion of interpersonally directed looks that were positive; (b) in the Strange Situation, a higher proportion (8 out of 10) of infants of borderline mothers were categorized as Disorganized; and (c) in play, mothers with BPD were rated as more “intrusively insensitive” toward their infants. The results are discussed in relation to hypotheses concerning the interpersonal relations of women with BPD, and possible implications for their infants' development.This research was generously supported by grants from the Winnicott Trust, the Hayward Foundation, and the Baily Thomas Charitable Fund, as well as by a Wellcome Fellowship to Matthew Patrick and an NIH Fellowship to Lisa Crandell. We also received support from the UK National Health R&D Budget. We are indebted to the mothers and infants who agreed to take part, Lynne Murray for inspiration and guidance, Lucy Chiemielski and Leezah Hertzmann for their help with ratings of videotapes, Betty Carlson and Alan Sroufe for their invaluable and very generous input, and Jessica Meyer for her helpful comments and suggestions.
Melanoma Recognition using Kernel Classifiers

Melanoma is the most deadly skin cancer. Early diagnosis is a current challenge for clinicians. Current algorithms for skin lesions classification focus mostly on segmentation and feature extraction. This paper instead puts the emphasis on the learning process, proposing two kernel-based classifiers: support vector machines, and spin glass-Markov random fields. We benchmarked these algorithms against a state-of-the-art method on melanoma recognition. We show with extensive experiments that the support vector machine approach outperforms the other methods, proving to be an effective classification algorithm for computer assisted diagnosis of melanoma.
Trans-Golgi network delivery of synaptic proteins in synaptogenesis

Synapse formation, stabilization and maintenance comprise several remarkably precise and rapid stages. The initial steps involve delivery to the site of initial contact between axon and dendrite of transport carriers containing several sets of synaptic proteins necessary for proper synaptic function. This occurs both pre- and postsynaptically and is mediated by apparently distinct vesicular carriers that fuse with the synaptic plasma membrane to deliver receptors for neurotransmitters, ion channels, transporters and pumps. The presynaptic carriers in the developing axon give rise to synaptic vesicles. On the postsynaptic side, the so-called spine apparatus may represent a tubular reservoir that gives rise to the postsynaptic players in synaptic function. Recent evidence indicates that recognition molecules, particularly neural cell adhesion molecule (NCAM), are associated with trans-Golgi-network-derived structures and thus can provide a signal for accumulation of these transport carriers at nascent synapses.
El rol mediador del Compromiso Organizacional entre la Satisfacción Laboral y la Intención de Permanencia en el sector de Contact Centers

Turnover is a phenomenon with important effects on organizations productivity. This study assessed the role that organizational commitment (affective, normative and continuance) as a mediator in the relationship between job satisfaction and intent to stay. The study involved 409 advisors of a contact center company of Medellin city in Colombia. The findings obtained through structural equation analysis showed that the organizational commitment (affective) partially mediates the relationship between job satisfaction and intent to stay. It was also found that job satisfaction is related positively and significantly with organizational commitment (affective, normative and continuance) and with intent to stay. These findings allow the companies to focus its management on matters that ensure the permanence of people. Received: 16/09/2015 Accepted: 18/01/2016 How to reference this article: Cortina, E.

Effects of neuroleptic medications on speech disorganization in schizophrenia: biasing associative networks towards meaning

Background. While some cognitive accounts of disorganized speech, or thought disorder, in schizophrenia have emphasized failures in working memory/discourse planning or selective attention, we have suggested that thought disorder resides in the semantic system. In this study we assessed the effect of neuroleptic medication on thought disorder and semantic processing. Methods. Seventeen patients with schizophrenia were assessed while receiving neuroleptic medications and in crossover fashion, placebo. A number of measures were obtained: clinically rated thought disorder (using the Thought, Language and Communication Scale); working memory (letter number span); lexical integrity (naming and receptive vocabulary); and, semantic priming of intracategorical word pairs. Results. Semantic priming measures improved with neuroleptic medication, as did clinically rated thought disorder. No other measure changed significantly. Priming selectively covaried with changes in thought disorder. Conclusion. Changes in spreading semantic activation, measured in a semantic priming paradigm and presumably brought about by neuroleptics' influence on dopaminergic neuromodulatory systems, might reflect changes in the biases of pre-existing associative networks that favour or increase the accessibility of representations related by shared features. This study also has implications for the architecture of normal language in that a dissociation between the lexical and semantic levels was observed, due to the selective compromise of tasks demanding semantic processing.
The modulatory role of cytokines IL‐4 and IL‐17 in the functional activity of phagocytes in diabetic pregnant women

The study investigated the role of cytokines IL‐4 and IL‐17 in the modulation of the functional activity of mononuclear phagocytes in diabetic pregnant women with hyperglycemia. Sixty pregnant women were assigned to the following groups: nondiabetic (ND), mild gestational hyperglycemia (MGH), gestational diabetes mellitus (GDM), or type 2 diabetes mellitus (DM2). The functional activity of phagocytes from maternal blood, cord blood, and colostrum was assessed by determining their superoxide release, phagocytosis, microbicidal activity, and intracellular Ca2+ release. Irrespective of glycemic status, colostrum and blood cells treated with IL‐4 and IL‐17 increased superoxide release in the presence of enteropathogenic Escherichia coli (EPEC). The highest phagocytosis rate was observed in cells from the DM2 group treated with IL‐4. In all the groups, phagocytes from colostrum, maternal blood, and cord blood exhibited higher microbicidal activity against EPEC when treated with cytokines. IL‐17 increased intracellular Ca2+ release by colostrum phagocytes in diabetic groups. The results indicate that the IL‐4 and IL‐17 modulate the functional activity of phagocytes in the maternal blood, cord blood, and colostrum of diabetic mother. The natural immunity resulting from the interaction between the cells and cytokines tested may be an alternative procedure to improve the prognosis of maternal and newborn infections.
Étude Préliminaire Entre L’Attachement Amoureux et la Dramatisation Face à la Douleur chez des Individus Vivant Avec de la Douleur Chronique

The objective of this preliminary study is to examine the perception of the support displayed by the romantic partner as a mediator of the relationship between the emotional attachment of the patient (there is anxiety related to abandonment and avoidance of intimacy) and the level of pain catastrophizing expressed by the patient. The sample being analyzed is comprised of 46 adults who live on a daily basis with chronic pain and who have been in a relationship for at least 6 months. The participants have completed the Experiences in Close Relationships, the Perceived Responsiveness Scale and the Pain Catastrophizing Scale. Results indicate that the more an individual has an insecure attachment; the less he/she will perceive receiving support from his/her romantic partner. The anxiety related to abandonment is associated with more pain catastrophizing.
BpMatch: An Efficient Algorithm for a Segmental Analysis of Genomic Sequences

Here, we propose BpMatch: an algorithm that, working on a suitably modified suffix-tree data structure, is able to compute, in a fast and efficient way, the coverage of a source sequence S on a target sequence T, by taking into account direct and reverse segments, eventually overlapped. Using BpMatch, the operator should define a priori, the minimum length l of a segment and the minimum number of occurrences minRep, so that only segments longer than l and having a number of occurrences greater than minRep are considered to be significant. BpMatch outputs the significant segments found and the computed segment-based distance. On the worst case, assuming the alphabet dimension d is a constant, the time required by BpMatch to calculate the coverage is O(l2n). On the average, by setting l≥ 2 logd(n), the time required to calculate the coverage is only O(n). BpMatch, thanks to the minRep parameter, can also be used to perform a self-covering: to cover a sequence using segments coming from itself, by avoiding the trivial solution of having a single segment coincident with the whole sequence. The result of the self-covering approach is a spectral representation of the repeats contained in the sequence. BpMatch is freely available on: www.sourceforge. net/projects/bpmatch/.
An Introduction to Copulas

These notes provide an introduction to modeling with copulas. Copulas are the mechanism which allows us to isolate the dependency structure in a multivariate distribution. In particular, we can construct any multivariate distribution by separately specifying the marginal distributions and the copula. Copula modeling has played an important role in finance in recent years and has been a source of controversy and debate both during and since the financial crisis of 2008 / 2009.
Continuous speech recognition by adaptive temporal radial basis function

This work presents the adaptive temporal radial basis function "ATRBF" applied to continuous speech recognition, in particular the recognition of phonemes. ATRBF combines features from time delay neural network "TDNN" and the advantages of radial basis function "RBF". The capacity to detect the acoustic features and their independent temporal report of the temporal localisation is inspired from the TDNN model. The main use of radial basis functions is both their speed of treatment and few parameters to adjust for the training phase, which encourages applying this model to new tasks in most delicate cases. The algorithm automatically selects the significant RBF centres and estimates the weights and delay at the same time. The adaptability is obviously when applying this approach in speech recognition, especially for phoneme recognition. This resemble to what would make a human brain in like situation.
AN ASSESSMENT OF LINEAR WRIST MOTION DURING THE TAKING OF A BITE OF FOOD

Motivated by the goal of building a device capable of detecting when a user takes a bite of food, we examine whether there is a correlation between linear wrist motion and bite detection. Such a device could be used to manage weight loss by tracking eating trends over time and providing real time feedback to the user regarding eating rate or total consumption. A comprehensive analysis of tracking linear motion using low cost inertial sensors is presented. Based on this theory, we discuss the design and tracking accuracy of a prototype bite counting device. We show that tracking position using low cost, off-the-shelf sensors is impractical over any sustained period of time. However, by detecting peaks in acceleration data we are able to look for a characteristic motion during eating. We recorded data from subjects eating a meal while wearing the device. Their wrist motions were analyzed in an attempt to identify a characteristic linear motion of the wrist that corresponds to the taking of a bite of food. Our results indicate that there is too much variability in motion during eating to detect bites of food based on acceleration peaks alone.
Ibis: a flexible and efficient Java‐based Grid programming environment

In computational Grids, performance‐hungry applications need to simultaneously tap the computational power of multiple, dynamically available sites. The crux of designing Grid programming environments stems exactly from the dynamic availability of compute cycles: Grid programming environments (a) need to be portable to run on as many sites as possible, (b) they need to be flexible to cope with different network protocols and dynamically changing groups of compute nodes, while (c) they need to provide efficient (local) communication that enables high‐performance computing in the first place. Existing programming environments are either portable (Java), or flexible (Jini, Java Remote Method Invocation or (RMI)), or they are highly efficient (Message Passing Interface). No system combines all three properties that are necessary for Grid computing. In this paper, we present Ibis, a new programming environment that combines Java's ‘run everywhere’ portability both with flexible treatment of dynamically available networks and processor pools, and with highly efficient, object‐based communication. Ibis can transfer Java objects very efficiently by combining streaming object serialization with a zero‐copy protocol. Using RMI as a simple test case, we show that Ibis outperforms existing RMI implementations, achieving up to nine times higher throughputs with trees of objects.

A Study of Students' Experiences of Mobile Learning

These days mobile phones are ubiquitous with everyone and there is lot of craze for messanger applications. Researchers has oftenly found their students asking them "Do you use WhatsApp? " or "Are you on we chat? ". This tickled their mind and made them think how these mobile applications can help in education. This very thought triggered the first step to this research. During session 2013- 2014, 37 student of B.Ed. (Bachelors in Education) programme were selected. All the selected students were using smart phones and mobile application named 'WhatsApp'. A WhatsApp group was created and students & teacher interacted with each other through it during 40 days teaching practice schedule. After the end of teaching practice schedule, students were asked to fill in the questionnaire on the experiences of WhatsApp m learning and for knowing their attitude towards it. For in depth analysis, Interviews of 10 randomly selected students' was also taken. Findings of the study show that student find learning through WhatsApp very interesting and educationally useful. They found that their social interactivity with their peers and teacher has increased moreover they learned collaboratively. The attitude of the students toward WhatsApp m learning was favorable. The study also revealed that married students found learning through WhatsApp disruptive and that they prefer learning in traditional classroom as it does not collide with their family time.
"IT WORKS FOR US.": THE DYNAMICS OF INFLUENCE AND INTIMACY WITHIN COUPLES

The goals of this study were to investigate the definitions of influence and closeness from the perspectives of the couples, the techniques or approaches couples use to share influence and maintain closeness in their relationships, the themes associated with different relating styles, ways couples handle discrepancies and incompatibilities, and the relationship issues associated with specific relating styles. Eight married couples residing in northeast Kansas were interviewed for this study. The participants were selected through a screening survey distributed to a university student body to collect basic demographics and couple relating styles. The eight couples were chosen because the relating styles they reported were diverse enough to provide the needed maximum variation and a general representation of the sample pool. A style of relating model – couple map was created to help couples visualize how they relate to their partners in terms of influence and closeness. This study begins to fill the gap in the research by creating an integrated model to understand couple relational patterns and by giving voice to couples and allowing them to share their experiences on how they share influence and maintain closeness in their relationships. Through the lens of Symbolic Interaction Theory and Social Exchange Theory, this study sheds light on the cognitive and behavioral strategies couples use to relate to each other while striving to meet personal and mutual needs for influence and closeness in their marriages. “IT WORKS FOR US. ”: THE DYNAMICS OF INFLUENCE AND INTIMACY WITHIN COUPLES
Finite-Temperature Micromagnetism

It is investigated how magnetic hysteresis is affected by finite-temperature excitations, using soft regions in hard-magnetic matrices as model systems. In lowest order, magnetization processes are described by the traditional approach of using finite-temperature materials constants such as K1 (T). Nanoscale excitations are usually small perturbations. For example, a Bloch summation over all magnon wave vectors shows that remanence is slightly enhanced, because long-wavelength excitations are suppressed. However, a reverse magnetic field enhances the effect of thermal excitations and causes a small reduction of the coercivity. To describe such effects, we advocate micromagnetic calculations where finite-temperature fluctuations are treated as small corrections to the traditional approach, as contrasted to full-scale Monte Carlo simulations.
Treatment of AIDS‐associated progressive multifocal leukoencephalopathy with highly active antiretroviral therapy

Objectives:To evaluate the efficacy of highly active antiretroviral therapy (HAART) in 12 patients with AIDS-associated progressive multifocal leukoencephalopathy (PML). Patients and methods:The diagnosis of PML was established by brain biopsy in six patients and by neuroimaging findings and PCR detection of JC virus in cerebrospinal fluid (CSF) in six patients. We also studied 13 consecutive AIDS patients with biopsy-proven PML cared for in the same institution before HAART was available. Eleven patients of the HAART group and eight patients of the control group received intravenous arabinoside cytosine cycles. Results:With HAART, the median decrease in the HIV viral load was 3.58 log10 copies/ml and the median increase in the CD4 cell count was 74 × 106/l. The median survival time after PML diagnosis was 545 days in the HAART group and 60 days in the control group (P < 0.001, log-rank test). In the HAART group, the neurological deficits improved substantially in six patients and stabilized in six patients. Eleven patients underwent follow-up cranial computed tomography or magnetic resonance scan that showed improvement of PML lesions in 10 patients and stabilization in one patient. Follow-up CSF analysis showed clearance of JC virus in six out of seven patients who had an initial positive result. Conclusions:This study shows that HAART may increase the survival, clinical status and radiological features of AIDS patients with PML. Clearance of JC virus from CSF has been found, suggesting that immune reconstitution can interrupt the JC virus lytic cycle.
The role of non-minimum phase zeros in stability of infinite dimensional systems

In this article, the authors examine a class of transfer functions (the Nevanlinna class) and present a well known theorem about the location of the non-minimum phase zeros for the Nevanlinna class. Next, they relate the Nevanlinna class to the class of stabilizable transfer functions and find two necessary conditions for a transfer function to be stabilizable. One of the necessary conditions is a constraint on the non-minimum phase zeros of a plant and the other is a constraint on the unstable poles of the plant. The necessary condition is automatically satisfied by every finite dimensional plant, so our result is only interesting for infinite dimensional plants. Finally, the authors construct a transfer function that does not satisfy our condition and is not stabilizable. Upon examination of our example, they see a counterintuitive result: the transfer function does not have any unstable poles and the only reason it is unstable (and not stabilizable) is because of the non-minimum phase zeros.
Our Entrepreneurial Future: Examining the Diverse Attitudes and Motivations of Teens Across Gender and Ethnic Identity

The number of women creating new businesses is increasing, but the number involved in entrepreneurial activities is still much lower than the number of men.To better understand this gender disparity, the career motivations, self-perceptions, and attitudes of adolescents interested in becoming entrepreneurs are investigated. A literature review regarding similar and different motivations and attitudes of men and women involved in entrepreneurial activity is presented.Data from a previous study by Marlino and Wilson (2003) is utilized; a total of 5,000 seventh through twelfth graders completed an eight-page survey in April-June 2002.For the current study, 1,971 subjects were chosen because they indicated an interest in entrepreneurship. Measures were collected on leadership skills, motivations, and entrepreneurial interest.An ANOVA analysis was used to examine the data. The results of the study indicate that girls are less likely than boys to be interested in owning their own business.However, girls from minority groups exhibited a significantly higher interest in establishing their own business than white girls.The differences between each gender group and each racial subgroup are discussed, as are the possible reasons for the disparate characteristics and motivations of each subgroup.The implications of this study are provided, as are possible areas for future study and possible limitations.

Real-time Error Concealment in Compressed Digital Video Streams

When compressed video is transmitted through a data network, such as an ATM or a wireless network, data can be lost due to channel errors and/or congestion. Techniques that post-process the received video and conceal the errors in real-time are needed. In this paper we describe an implementation of error concealment techniques on the Texas Instruments TMS320C6201 (‘C6201) digital signal processor.
