Reduction of core network signalling overhead in cluster based LTE small cell networks

Small cell network strategies are applied for providing enhanced coverage and maximizing system capacity in the network. In such an environment, substantial growth of signalling load on the Core Network (CN) can be caused by reduced cell size, increased user density and increased user velocity. In this paper, in order to reduce the signalling load incurred by path switching operations in the small cell network, a new mobility control function, termed the Small Cell Controller (SCC) is introduced to the existing Base Station (BS) on the Radio-Access-Network(RAN)-side. Within a cluster, a designated SCC controls and manages a group of small cells and maintains associated forwarding information for UEs within a localized mobility management domain. When compared to the legacy scheme in the 3GPP, our simulation results show that the proposed RAN-side SCC is able to achieve the signalling reduction gain by up to 58.1% on the CN.
Harry Stack Sullivan and his chums: archive fever in American psychiatry?

The literature on the life and work of American psychiatrist Harry Stack Sullivan is used to provide a critique of Jacques Derrida’s Archive Fever. Derrida’s concept of archival violence relies on psychoanalysis both for its epistemology and for its exemplar of archival violence. The Sullivan literature shows how these positions become antagonistic when Derrida’s work is used to think about Freud’s critics. The published literature on Sullivan is described as a queer archive that has been strongly shaped by historical shifts in discourses about homosexuality, but that continues to stimulate and frustrate attempts to know the essential truth about Sullivan. Sullivan scholars have been quick to read his personality theory as autobiography, belittling the importance of friendship in Sullivan’s developmental theory, which differentiates it from the heteronormative Oedipal narrative. It is argued that Derrida’s mode of critique would entrench rather than unearth such heteronormative historiographical moves. Scholars are invited to put Sullivan’s biographies and published works to a broader range of uses in the human sciences.
Load theory of selective attention and the role of perceptual load: Is it time for revision?

Perceptual load hypothesis is proposed as a compromise between early and late theory of selective attention which states that the selection will operate early when the load on perception is high and it will operate late when the load on perception is low. Experimental findings have shown that the perceptual load hypothesis is too simplistic in nature as perceptual load is not the only determinant of selection processes. It is difficult to apply the load hypothesis to explain the occurrence of early selection in low load displays as well as the selection processes that operate on distractor and target stimuli that are a part of the same object. Factors like spatial proximity, cues that manipulate the spatial extent of attentional focus, salience of targets as well as the distractors, and perceptual grouping between the target and the distractors should be taken into account while explaining the selective control of attention. Thus, the perceptual load of the display is one such factor that affects selective attention and goal-directed behaviour, but it is not the only factor to affect the selective control of attention.
A Quantitative Signature of Self-Control Repair

Excessive temporal discounting undergirds addiction, and the quantitative relationships of changes in discounting have yet to be investigated. The quantitative relationship between pre- and posttreatment discount rates was examined using data from five of our studies with diverse interventions across different groups of substance users. Discounting and treatment-outcome drug-use data from 222 drug-dependent individuals were analyzed. The primary measures were discounting of delayed reinforcers and objective measures of drug use. Results revealed that change in discounting was inversely related to baseline rates of discounting, such that participants with low discount rates showed little change in discounting with treatment, whereas participants with high discount rates showed large reductions in discounting. As importantly, those treatments that produced the largest gains in drug abstinence had the largest effects on discount rates. Temporal discounting changes with the specific quantitative signature of rate dependence, and more efficacious treatments remediate high discounting rates.
Online news consumption research: An assessment of past work and an agenda for the future

This article assesses the main findings and dominant modes of inquiry in recent scholarship on online news consumption. The findings suggest that the consumption of news on the internet has not yet differed drastically from the consumption of news in traditional media. The assessment shows that the dominant modes of inquiry have also been characterized by stability rather than change (because research has usually drawn on traditional theoretical and methodological approaches). In addition, these modes of inquiry exhibit three systematic limitations: the assumption of a division between print, broadcast, and online media; the notion that the analysis should treat media features and social practices separately; and the inclination to focus on ordinary or extraordinary patterns of phenomena but not on both at the same time. On the basis of this assessment, this article proposes an integrative research agenda that builds on this scholarship but also contributes to solve some of its main limitations.
Factors contributing towards patient’s choice of a hospital clinic from the patients’ and managers’ perspective

Introduction Given the competitive nature of the health market and the multiplicity of factors that may contribute towards patient’s choices of a hospital, patients’ needs and preferences for a hospital must be considered in the planning and decision making of hospitals and health care organizations. This study aimed to identify the factors that contribute to patient’s choices of a clinic and the importance of each factor. Methods A mixed-method approach was used to collect quantitative and qualitative data in two phases. The study was conducted in a hospital clinic in 2014. Qualitative data were collected by face-to-face semi-structured interviews of a sample of 22 managers and heads of outpatient wards. The self-administered questionnaire designed for this study collected quantitative data from a stratified random sample of 381 patients referred to this clinic. The qualitative data were analyzed by a system of coding, while parametrical statistical analyses were conducted to analyze the quantitative data using the independent-samples t-test and ANOVA in SPSS software, version 21.0. Results The qualitative data indicated that there were 21 factors that may contribute to patient’s choices of a clinic, and these factors were classified into six categories, i.e., facilities and physical assets, physicians and employees, location and place, services, price, and promotion. Among the 16 questions studied in the quantitative questionnaire, the highest and lowest means were related to “appropriate clinic environment” (2.47 ± 0.58) and “advertising through TV and radio, the Internet, newspapers, etc.” (1.77 ± 0.75), respectively. There were significant associations between “having experienced and responsive personnel, including physicians and employees” and the patient’s gender and frequency of referrals, between “belonging to the Armed Forces” and the patient’s age and frequency of referrals, between “advertising through TV and radio, the Internet, newspapers, etc.” and shifts and frequency of referrals, between “inadequate facilities and poor quality of services provided in other health care organizations of the Armed Forces” and “adornment and good behavior of staff” and shifts (p < 0.05). Conclusion The most significant contributing factors to attract patients were the “physicians and employees,” and “the clinic’s environment. ” Therefore, it is essential for clinic managers and heads of outpatient wards to focus on and strengthen these two factors. Also, since the means of the factors were better in the morning shift, the employees should perform their duties properly and consistently in all shifts.
Diet restriction in migraine, based on IgG against foods: A clinical double-blind, randomised, cross-over trial

Introduction: It is well-known that specific foods trigger migraine attacks in some patients. We aimed to investigate the effect of diet restriction, based on IgG antibodies against food antigens on the course of migraine attacks in this randomised, double blind, cross-over, headache-diary based trial on 30 patients diagnosed with migraine without aura. Methods: Following a 6-week baseline, IgG antibodies against 266 food antigens were detected by ELISA. Then, the patients were randomised to a 6-week diet either excluding or including specific foods with raised IgG antibodies, individually. Following a 2-week diet-free interval after the first diet period, the same patients were given the opposite 6-week diet (provocation diet following elimination diet or vice versa). Patients and their physicians were blinded to IgG test results and the type of diet (provocation or elimination). Primary parameters were number of headache days and migraine attack count. Of 30 patients, 28 were female and 2 were male, aged 19–52 years (mean, 35 ± 10 years). Results: The average count of reactions with abnormally high titre was 24 ± 11 against 266 foods. Compared to baseline, there was a statistically significant reduction in the number of headache days (from 10.5 ± 4.4 to 7.5 ± 3.7; P < 0.001) and number of migraine attacks (from 9.0 ± 4.4 to 6.2 ± 3.8; P < 0.001) in the elimination diet period. Conclusion: This is the first randomised, cross-over study in migraineurs, showing that diet restriction based on IgG antibodies is an effective strategy in reducing the frequency of migraine attacks.
Transparent Rendering of Tool Contact with Compliant Environments

Transparent haptic rendering of the contact between a tool and its environment requires very frequent update of the contact forces acting on the tool. Given a rigid tool and a deformable environment, we define contact constraints by solving a constrained dynamic simulation problem, typically at a low update rate. A generalized contact Jacobian defines velocities at the constraints given the velocity of the rigid tool. We define an inverse of the contact Jacobian that is dynamically consistent with the constraints and, once we know other forces acting on the rigid tool, it allows a fast update of the accumulated contact forces, and thereby highly transparent rendering
GIP increases human adipocyte LPL expression through CREB and TORC2-mediated trans-activation of the LPL gene

GIP (glucose-dependent insulinotropic polypeptide) is a gastrointestinal hormone that regulates pancreatic islet function. Additionally, emerging evidence suggests an important physiological role for GIP in the regulation of adipocyte metabolism. In previous studies on the lipogenic effects of GIP, it was shown to increase adipocyte lipoprotein lipase (LPL) activity in both differentiated 3T3-L1 cells and human adipocytes through a pathway involving activation of protein kinase B (PKB)/Akt. In the current study, we examined the effects of GIP on LPL gene expression. GIP in the presence of insulin increased LPL gene expression in human adipocytes and LPL promoter activity in GIP receptor-expressing HEK-293 cells, and both effects were greatly reduced by the transcription inhibitor actinomycin D. Subsequent studies established that GIP increased phosphorylation of Serine 133 in cAMP-response element binding protein (CREB) and the nuclear localization of cAMP-responsive CREB coactivator 2 (TORC2) through a pathway involving phosphatidylinositol 3-kinase (PI3-K), PKB, and AMP-activated protein kinase (AMPK). However, in the presence of insulin, GIP failed to activate the cAMP/PKA pathway. Knockdown of CREB and TORC2 using RNA interference reduced LPL expression, supporting a functional regulatory role. GIP-induced phospho-CREB and TORC2 were shown to bind to a cAMP-response element (-II) site in the human LPL promoter and GIP increased protein-protein interactions of these two factors. The lipogenic effects of GIP in the presence of insulin are therefore at least partially mediated by upregulation of adipocyte LPL gene transcription through a pathway involving PI3-K/PKB/AMPK-dependent CREB/TORC2 activation.
Childlessness and psychological well‐being in Chinese older adults

Childless older adults will increase rapidly in the coming future due to delayed marriage, infertility, and high divorce rate. We examined whether childlessness is significantly related to loneliness and depression and whether the effect of childlessness persisted even when other factors including gender, marital status, age, education, self‐rated health status and financial strain were controlled for.
Supporting skill acquisition in cochlear implant surgery through virtual reality simulation

Objectives: To evaluate the effectiveness of a virtual reality (VR) temporal bone simulator in training cochlear implant surgery. Methods: We compared the performance of 12 otolaryngology registrars conducting simulated cochlear implant surgery before (pre-test) and after (post-tests) receiving training on a VR temporal bone surgery simulator with automated performance feedback. The post-test tasks were two temporal bones, one that was a mirror image of the temporal bone used as a pre-test and the other, a novel temporal bone. Participant performances were assessed by an otologist with a validated cochlear implant competency assessment tool. Structural damage was derived from an automatically generated simulator metric and compared between time points. Results: Wilcoxon signed-rank test showed that there was a significant improvement with a large effect size in the total performance scores between the pre-test (PT) and both the first and second post-tests (PT1, PT2) (PT-PT1: P = 0.007, r = 0.78, PT-PT2: P = 0.005, r = 0.82). Conclusion: The results of the study indicate that VR simulation with automated guidance can effectively be used to train surgeons in training complex temporal bone surgeries such as cochlear implantation.
Nonlinear Adaptive Control of a Piston Pump Mock Ventricle

High-performance control system for a piston pump mock ventricle is developed in this research to accurately reproduce the native ventricle's pumping dynamics and to secure the physiological feasibility of the cardiovascular circulatory simulator (CCS). The challenges are that a piston pump mock ventricle has inherent parameter uncertainties of check valve resistances, high bandwidth pressure dynamics, and hard nonlinearity due to check valves. To overcome these difficulties, a nonlinear adaptive control scheme is presented in this paper. A hardware CCS is constructed based on the electrical-analog reference model of the cardiovascular circulatory system and the mathematical model of the hardware was derived using fluidic element modeling and the parameter identification experiments. The adaptive controller was designed based on the derived model. Experimental results show that the adaptive control achieved outstanding control performance in spite of the parameter uncertainties and yielded a good match with the reference model behavior. As a result, high quality elastance curve over the whole cardiac cycle was made possible at the level that has never been achieved.
Rising to the occasion: Disaster social work in China

The fifth year since the deadly Wenchuan earthquake that killed more than 87,000 people will be commemorated in 2013. This article critically reviews the development and charts the direction of disaster social work in China, since the fateful 2008 Wenchuan earthquake jump-started it dramatically. While disaster social work publications, social work projects and organizations surged, young Chinese social workers felt challenged by poor professional recognition, harsh working conditions and limited prospects and support. However, they have been spurred onwards by the resilience and growth of their clients and professional fulfilment in the daunting process of recovery and reconstruction.
In Silico Reconstitution of Listeria Propulsion Exhibits Nano-Saltation

To understand how the actin-polymerization-mediated movements in cells emerge from myriad individual protein–protein interactions, we developed a computational model of Listeria monocytogenes propulsion that explicitly simulates a large number of monomer-scale biochemical and mechanical interactions. The literature on actin networks and L. monocytogenes motility provides the foundation for a realistic mathematical/computer simulation, because most of the key rate constants governing actin network dynamics have been measured. We use a cluster of 80 Linux processors and our own suite of simulation and analysis software to characterize salient features of bacterial motion. Our “in silico reconstitution” produces qualitatively realistic bacterial motion with regard to speed and persistence of motion and actin tail morphology. The model also produces smaller scale emergent behavior; we demonstrate how the observed nano-saltatory motion of L. monocytogenes, in which runs punctuate pauses, can emerge from a cooperative binding and breaking of attachments between actin filaments and the bacterium. We describe our modeling methodology in detail, as it is likely to be useful for understanding any subcellular system in which the dynamics of many simple interactions lead to complex emergent behavior, e.g., lamellipodia and filopodia extension, cellular organization, and cytokinesis.
Multiculturalism and young people’s leisure spaces in Finland: perspectives of multicultural youth

The article sums up the main results of a research project Multicultural Youth, Leisure and Participation in Civic Activities carried out in Finland 2004–2007. Through empirical analyses, interpretations can be made concerning the readiness of youth’s leisure communities to adapt to the situation where their members are more and more diverse with regard to their cultural and ethnic backgrounds. Formal education and labour market are crucial but not the only significant areas of integration, especially when young people are in the focus of discussion. Tolerance for multiculturalism in leisure environments and youth communities is still a topic, which has remained largely unexplored. Multicultural youth, whose experiences are analysed in this article, seem to share the opinion that concrete and continuous forms of multicultural leisure action are often lacking, as well as active participants with divergent ethnic backgrounds. The experiences of multicultural youth thus challenge the general optimism of an anti-racist leisure policy. Skin colours, cultural distances and ethnic hierarchies are still elements that regulate informally youth’s possibilities to participate in common leisure activities.
Cognitive, Instructional, and Social Presence as Factors in Learners' Negotiation of Planned Absences from Online Study.

Adult learners value the flexibility and convenience offered to them as online learners, and many learners are required to absent themselves from their online classes during courses in order to accommodate demanding schedules. What factors and tensions contribute to learners’ decision-making at these times? This qualitative study considered the planned absences of learners engaged in an online graduate course at a large university. Working within the framework provided by cognitive, instructional, and social presences, findings showed the following: (1) learners understood and accommodated the relationship and importance of the affective domain to their cognitive successes in learning, (2) successful learners demonstrated insightful self-knowledge in using meta-cognitive strategies, and (3) learners’ external support systems were fundamental to their ability to continue to learn when absences occurred. The study’s findings corroborate other recent research that similarly stresses the complexity and interrelated nature of the adult learning process.
Content and Structure of Values in Middle Adolescence: Evidence From Singapore, the Philippines, Indonesia, and Australia

Schwartz’s theory of the content and structure of human values has been validated mostly with adult (teacher and university student) samples. The present study examines the content and structure of values of middle adolescents in Singapore, the Philippines, Indonesia, and Australia. The 40-item version of the Portrait Values Questionnaire was administered to 230 adolescents in each country (total N = 920; boys and girls were equal) and smallest space analysis was performed. Consistent with theory, the 10 first-order values and the four second-order values, organized in two bipolar dimensions, were identified in all samples. In support of the developmentally modified value model for young people, there was some evidence for the periphery of power to achievement. Interestingly, the location of benevolence and universalism were reversed across all cultural groups, and tradition values separated into self-restriction and faith. Overall, the findings support the claim that Schwartz’s theory of values is neither restricted to adults nor solely based on a particular instrument and is generalizable across diverse national contexts.
Appealing to Good Students in Introductory Economics

Abstract The authors examine the effectiveness of different teaching techniques using a unique data set that allows them to match student and instructor characteristics to assess their impact on students' interest in economics. They find that devoting less class time to lecture and more to discussion is effective for all types of students. However, the magnitude of the effects of these two techniques varies considerably by type of student, as does the impact of several other teaching techniques. They conclude that using a variety of teaching techniques is the most successful strategy to appeal to the broad range of learning styles adopted by “good” students.
‘As Good as it's Going to Get’. Bad News Conversations in Neurology: Challenges for Occupational Therapists

Introduction: This exploratory study sought to answer the question, ‘What are the experiences of neurological occupational therapists when having bad news conversations with disabled people regarding likely levels of long-term disability? ’. Method: The study design was a retrospective qualitative method within a phenomenological methodology. Convenience sampling was used to identify occupational therapists working with neurologically impaired adults. Ten semi-structured interviews using a topic guide were conducted. Ethical approval was granted by the Faculty Research Ethics Committee. Findings: Participants had bad news conversations prior to discharge and there was a functional focus. Four approaches to these conversations emerged: collaboration, being direct, avoidance and using a client-centred approach. Strategies included use of pre-discharge home visit, goal setting, using others, maintaining hope and communication skills. The participants agreed that this task has an emotional cost. Conclusion: Bad news conversations are an important and sometimes difficult clinical task that can have an impact on the quality of the therapeutic relationship. Little has been documented regarding occupational therapists' conversations relating to living with long-term disability. This study has underlined the importance of addressing this task in undergraduate education and also in the supervision of junior occupational therapists.
