A Framework for Bandwidth Management and Call Admission Control in ATM Networks Sponsor: Sprint Corporation

One critical issue in tra c management of ATM networks is, to achieve the balance between two seemingly con icting goals: to guarantee the Quality of Service (QoS) for all service classes, while still allowing enough statistical sharing of bandwidth so that the network is e ciently utilized. Guaranteeing QoS requires tra c isolation, as well as allocation of enough network resource (e.g. bu er space and bandwidth) to each call. However, the statistical bandwidth sharing means the network resource should be occupied on-demand, leading to less tra c isolation and minimal resource allocation. Due to the complicated nature of this problem, no single measure can possible provide the proper solution. Rather, a comprehensive solution incorporating the schemes dealing with di erent aspects of the problem is necessary. In this thesis, we try to address the problem by proposing a framework for bandwidth management and connection admission control, into which further detailed control measures may be added later. In the rst part of this thesis, we propose and evaluate a networkwide bandwidth management architecture in which an appropriate compromise between the two con icting goals is achieved. Speci cally, the bandwidth management framework consists of a network model and a network-wide bandwidth allocation and sharing strategy. Implementation issues related to the framework are discussed. For real time applications, we obtain maximum queueing delay and queue length which are important in bu er design and VP (Virtual Path) routing. Furthermore, we propose a measurement-based CAC strategy based on the proposed architecture. We rst discuss how to obtain an accurate description (UPC parameters) of user tra c by using trace-based measurement in conjunction with on-line measurement and dynamic renegotiation. The results show that the proposed strategy is reliable and simple to implement. We then move on to examine the possibility and methodology for exploiting the e ect of statistical multiplexing in resource allocation to achieve higher network resource utilization. i
Education as a Social Determinant of Health: Issues Facing Indigenous and Visible Minority Students in Postsecondary Education in Western Canada

The level of educational attainment is increasingly being recognized as an important social determinant of health. While higher educational attainment can play a significant role in shaping employment opportunities, it can also increase the capacity for better decision making regarding one’s health, and provide scope for increasing social and personal resources that are vital for physical and mental health. In today’s highly globalized knowledge based society postsecondary education (PSE) is fast becoming a minimum requirement for securing employment that can afford young adults the economic, social and personal resources needed for better health. Canada ranks high among OECD countries in terms of advanced education, with 66% of Canadians having completed some form of postsecondary education. Yet youth from low income indigenous and visible minority (LIIVM) backgrounds continue to be poorly represented at PSE levels. The current study aimed to understand the reasons for this poor representation by examining the experiences of LIIVM students enrolled in a postsecondary program. Findings show that the challenges they faced during the course of their study had an adverse impact on their health and that improving representation of these students in PSE will require changes at many levels.
T2
 * Dependence of Low Frequency Functional Connectivity

Resting state low frequency (<0.08 Hz) fluctuations in MR timecourses that are temporally correlated between functionally related areas have been observed in recent studies. These fluctuations have been assumed to arise from spontaneous blood oxygenation level-dependent (BOLD) oscillations. This work examines the T(2)(*) characteristics of the low frequency fluctuations (functional connectivity) and compares them to those of task activation induced signal changes. Multi-echo spiral data were fit using a mono-exponential decay model to generate T(2)(*) and intensity (I(0)) parameter timecourses. Resultant correlation maps show that both functional connectivity and BOLD activation modulate T(2)(*), not I(0). Regression analysis also finds that both have a linear dependence on echo time. Thus, functional connectivity and task activation MR signal changes appear to arise from the same BOLD-related origins.
Nonassociative Learning Promotes Respiratory Entrainment to Mechanical Ventilation

Background Patient-ventilator synchrony is a major concern in critical care and is influenced by phasic lung-volume feedback control of the respiratory rhythm. Routine clinical application of positive end-expiratory pressure (PEEP) introduces a tonic input which, if unopposed, might disrupt respiratory-ventilator entrainment through sustained activation of the vagally-mediated Hering-Breuer reflex. We suggest that this potential adverse effect may be averted by two differentiator forms of nonassociative learning (habituation and desensitization) of the Hering-Breuer reflex via pontomedullary pathways. Methodology/Principal Findings We tested these hypotheses in 17 urethane-anesthetized adult Sprague-Dawley rats under controlled mechanical ventilation. Without PEEP, phrenic discharge was entrained 1∶1 to the ventilator rhythm. Application of PEEP momentarily dampened the entrainment to higher ratios but this effect was gradually adapted by nonassociative learning. Bilateral electrolytic lesions of the pneumotaxic center weakened the adaptation to PEEP, whereas sustained stimulation of the pneumotaxic center weakened the entrainment independent of PEEP. In all cases, entrainment was abolished after vagotomy. Conclusions/Significance Our results demonstrate an important functional role for pneumotaxic desensitization and extra-pontine habituation of the Hering-Breuer reflex elicited by lung inflation: acting as buffers or high-pass filters against tonic vagal volume input, these differentiator forms of nonassociative learning help to restore respiratory-ventilator entrainment in the face of PEEP. Such central sites-specific habituation and desensitization of the Hering-Breuer reflex provide a useful experimental model of nonassociative learning in mammals that is of particular significance in understanding respiratory rhythmogenesis and coupled-oscillator entrainment mechanisms, and in the clinical management of mechanical ventilation in respiratory failure.
A System for Induction of Oblique Decision Trees

This article describes a new system for induction of oblique decision trees. This system, OC1, combines deterministic hill-climbing with two forms of randomization to find a good oblique split (in the form of a hyperplane) at each node of a decision tree. Oblique decision tree methods are tuned especially for domains in which the attributes are numeric, although they can be adapted to symbolic or mixed symbolic/numeric attributes. We present extensive empirical studies, using both real and artificial data, that analyze OC1's ability to construct oblique trees that are smaller and more accurate than their axis-parallel counterparts. We also examine the benefits of randomization for the construction of oblique decision trees.
Empowering refugee girls: a study of cultural orientation programs in Kenya and Sudan

This study is based on video observations of cultural orientation programs held for refugees being resettled to Sweden. It examines discussions of gender equality and aims to explore what ideas of gender equality the representatives presented and how they were received by the participating girls. The analysis shows how the representatives' work is rooted in an ideology of Sweden as a country of gender equality, which, I argue, is presented contrastively to the girls' background. The analysis identifies paradoxes in the representatives' talk: on the one hand, the girls are told about their rights and the importance of living a life based on freedom of one's own choice, whereas on the other hand the representatives inform them about just how that life ought to be lived in Sweden. The study contributes to limited research on resettlement and uncovers commonsensical assumptions of the other that need to be questioned in order to undermine tendencies of cultural imperialism. It highlights the importance of creating awareness among officials within contexts with unequal power relations. It also highlights the need to put the perspectives of marginalized groups at the center of attention in order to fulfill the aim of empowerment.
The Effects on Kinematics and Muscle Activity of Walking in a Robotic Gait Trainer During Zero-Force Control

“Assist as needed” control algorithms promote activity of patients during robotic gait training. Implementing these requires a free walking mode of a device, as unassisted motions should not be hindered. The goal of this study was to assess the normality of walking in the free walking mode of the LOPES gait trainer, an 8 degrees-of-freedom lightweight impedance controlled exoskeleton. Kinematics, gait parameters and muscle activity of walking in a free walking mode in the device were compared with those of walking freely on a treadmill. Average values and variability of the spatio-temporal gait variables showed no or small (relative to cycle-to-cycle variability) changes and the kinematics showed a significant and relevant decrease in knee angle range only. Muscles involved in push off showed a small decrease, whereas muscles involved in acceleration and deceleration of the swing leg showed an increase of their activity. Timing of the activity was mainly unaffected. Most of the observed differences could be ascribed to the inertia of the exoskeleton. Overall, walking with the LOPES resembled free walking, although this required several adaptations in muscle activity. These adaptations are such that we expect that Assist as Needed training can be implemented in LOPES.
Quality assurance of radiopharmaceuticals. Report of a joint working party: the UK Radiopharmacy Group and the NHS Pharmaceutical Quality Control Committee

In this issue, the UK Radiopharmacy Group presents its third report on the Quality Assurance of Radiopharmceuticals. This concentrates on facilities which prepare only short-lived materials (shelf-life <24 hours) on site, which covers the majority of units within the UK, but is applicable to all radiopharmacies. As has come to be expected, the advice is comprehensive and provides sound interpretation of both current and potential legislation/regulations/guidelines. It will enable existing units to carry out a rapid audit of their documentation and prove invaluable to those planning new facilities. Given the litigious milieu in which we now practise, this is a timely document.
Fundamental Capacity Limits of Spectrum-Sharing in Hoyt (Nakagami-q) Fading Channels

A channel capacity analysis is presented in this work for a spectrum-sharing cognitive radio link in which the fading experienced by the signal is modeled with the Hoyt (Nakagami-q) distribution. Based on a novel formulation of the squared Hoyt distribution derived by the authors, simple expressions for the capacity of the secondary link in a number of scenarios of interest are derived, which are given in terms of easy-to-compute finite-range integrals of elementary functions. The effect of fading severity in the secondary transmitter-primary receiver (ST-PR) and secondary transmitter-secondary receiver (ST-SR) links, and the impact of different antenna gains on the system performance are analyzed. We show that in the presence of severe fading for the ST-PR link, the capacity of the ST-SR link is increased.
Reintegrative Shaming and Predatory Delinquency

This study represents an attempt to test Braithwaite’s theory of reintegrative shaming with an operationalization scheme of two variables—disapproval of delinquent behavior (shaming) and forgiveness of the transgressor (reintegration) by parents and peers. The study combines measures of delinquency disapproval and forgiveness of the transgressor by parents and peers to capture the concept of reintegrative shaming. Using data collected from the first two waves of the National Youth Survey, the study finds no effect of either parental reintegrative shaming or peer reintegrative shaming on predatory delinquency in either wave when the effects of other important variables are held constant. However, the data reveal that parental forgiveness and peer shaming alone have significant and negative effects on the likelihood of being involved in predatory offenses in both waves. In contrast, peer forgiveness shows a significant and positive effect on predatory offense involvement in the first wave. The findings provide support to some elements of Braithwaite’s theory but not to the key hypothesis, assuming that reintegrative shaming is a significant predictor of predatory offenses. Implications of the findings and suggestions for future research are discussed.
Expanding the frontiers of protein–protein modeling: From docking and scoring to binding affinity predictions and other challenges

In addition to protein–protein docking, this CAPRI edition included new challenges, like protein–water and protein–sugar interactions, or the prediction of binding affinities and ΔΔG changes upon mutation. Regarding the standard protein–protein docking cases, our approach, mostly based on the pyDock scheme, submitted correct models as predictors and as scorers for 67% and 57% of the evaluated targets, respectively. In this edition, available information on known interface residues hardly made any difference for our predictions. In one of the targets, the inclusion of available experimental small‐angle X‐ray scattering (SAXS) data using our pyDockSAXS approach slightly improved the predictions. In addition to the standard protein–protein docking assessment, new challenges were proposed. One of the new problems was predicting the position of the interface water molecules, for which we submitted models with 20% and 43% of the water‐mediated native contacts predicted as predictors and scorers, respectively. Another new problem was the prediction of protein–carbohydrate binding, where our submitted model was very close to being acceptable. A set of targets were related to the prediction of binding affinities, in which our pyDock scheme was able to discriminate between natural and designed complexes with area under the curve = 83%. It was also proposed to estimate the effect of point mutations on binding affinity. Our approach, based on machine learning methods, showed high rates of correctly classified mutations for all cases. The overall results were highly rewarding, and show that the field is ready to move forward and face new interesting challenges in interactomics.

Modelling occupational stress and employee health and wellbeing in a Chinese higher education institution

Extensive change is evident in higher education in the People's Republic of China but there have been few studies of the effect of work stress on wellbeing in the higher education sector. The main aim of this study is to test and refine the ASSET (‘An Organizational Stress Screening Tool’) model of occupational stress in a sample of 150 academic and non-academic employees in a Chinese higher education institute. Using partial least squares modelling, the findings showed that job stressors predicted job dissatisfaction but, surprisingly, did not predict perceived commitment. Employees who reported job dissatisfaction tended to perceive that their organisation was less committed towards them and report less commitment towards the organisation. Job stressors resulted in poorer psychological wellbeing. Greater psychological wellbeing was associated with greater physical wellbeing. The findings suggest that university management should introduce strategies aimed at minimising job stressors as these would result in higher level of job satisfaction, higher level of commitment and ultimately resulted in an improvement in physical health.
Flux, gaugino condensation, and antibranes in heterotic M theory

We present the potential energy due to flux and gaugino condensation in heterotic M theory compactifications with antibranes in the vacuum. For reasons which we explain in detail, the contributions to the potential due to flux are not modified from those in supersymmetric contexts. The discussion of gaugino condensation is, however, changed by the presence of antibranes. We show how a careful microscopic analysis of the system allows us to use standard results in supersymmetric gauge theory in describing such effects - despite the explicit supersymmetry breaking which is present. Not surprisingly, the significant effect of antibranes on the threshold corrections to the gauge kinetic functions greatly alters the potential energy terms arising from gaugino condensation.
Inquiring into children’s experiences of teacher feedback: reconceptualising Assessment for Learning

Few previous studies have explored in detail how children respond affectively and cognitively to feedback in the normal interactions of the primary school classroom and how they relate feedback to their sense of autonomy. This paper reports on a longitudinal study of nine ‘profile’ children aged 9 to 10 years in a UK school. They were observed and video-filmed in threes, twos or individually during literacy and numeracy lessons across two terms from January to July 2010. The video-recordings were shown later the same day to the children who had been filmed, being stopped at frequent intervals to allow the participants to comment on specific feedback incidents. The children claimed that learning was frustrated by overly directive feedback and that their learning benefited when the teacher’s feedback included substantial but not burdensome detail. The children felt their learning was supported by feedback reminder cues and they noticed that negative and positive feedback provoked emotions which could interfere with or support learning. The article concludes by suggesting that Assessment for Learning might be conceptualised as a classroom conversation in which children as well as teachers assess how teacher feedback relates to children’s learning, which would itself constitute a major contribution to their autonomous learning.
In situ hybridization analyses of claustrum‐enriched genes in marmosets

The claustrum/endopiriform nucleus is a unique structure that sits between the striatum and the cerebral cortex. Recent genome‐wide mapping of gene expression in mice identified various genes concentrated in this structure, suggesting a requirement for a special set of genes for its function. In situ hybridization histochemistry was performed for such “claustrum‐enriched” genes in the marmoset brain. In marmosets, nurr1 and netrinG2 genes exhibited highly concentrated expression in the claustrum and endopiriform nucleus, as well as in a subpopulation of layer 6 neurons across the entire cortex, consistent with their expression patterns as described in macaques. Cux2 showed enriched expression in the upper layers (layers 2–4) and the claustrum/endopiriform nucleus. GNG2 was expressed strongly in the claustrum/endopiriform nucleus, but was abundant across cortical areas in a ventral high‐dorsal low gradient. Latexin was detected in the claustrum and dorsal endopiriform nucleus, but not in cortical regions. GNB4 and Tmem163 genes were both concentrated in the claustrum/endopiriform nucleus, as reported in mice, but their cortical expression in the marmoset differed from the mouse pattern. Thus, the gene set required for the claustrum appears to be broadly conserved across species, despite various differences that suggest species‐specific differentiation of brain architecture. J. Comp.

Trophic factor induction of human umbilical cord blood cells in vitro and in vivo

The mononuclear fraction of human umbilical cord blood (HUCBmnf) is a mixed cell population that multiple research groups have shown contains cells that can express neural proteins. In these studies, we have examined the ability of the HUCBmnf to express neural antigens after in vitro exposure to defined media supplemented with a cocktail of growth and neurotrophic factors. It is our hypothesis that by treating the HUCBmnf with these developmentally-relevant factors, we can expand the population, enhance the expression of neural antigens and increase cell survival upon transplantation. Prior to growth factor treatment in culture, expression of stem cell antigens is greater in the non-adherent HUCBmnf cells compared to the adherent cells (p < 0.05). Furthermore, treatment of the non-adherent cells with growth factors, increases BrdU incorporation, especially after 14 days in vitro (DIV). In HUCBmnf-embryonic mouse striata co-culture, a small number of growth factor treated HUCBmnf cells were able to integrate into the growing neural network and express immature (nestin and TuJ1) and mature (GFAP and MAP2) neural markers. Treated HUCBmnf cells implanted in the subventricular zone predominantly expressed GFAP although some grafted HUCBmnf cells were MAP2 positive. While short-term treatment of HUCBmnf cells with growth and neurotrophic factors enhanced proliferative capacity in vitro and survival of the cells in vivo, the treatment regimen employed was not enough to ensure long-term survival of HUCBmnf-derived neurons necessary for cell replacement therapies for neurodegenerative diseases.
Investigating the Relation Between Team Learning and the Team Situation Model

The development of a team situation model (TSM), a shared understanding of the current situation developed by team members moment by moment, and its impact on team effectiveness have received minor attention in team research. This study investigates a moderated mediation model including the relationship between the team learning processes of co-construction and constructive conflict, the TSM, and team effectiveness. Forty-seven emergency management command-and-control teams participated in this field study. Their task was to manage a realistic emergency simulation developed and organized by field experts. The multi-rater approach included ratings of team members, researchers, and field experts. Results show that co-construction is related to the TSM under the condition of high constructive conflict. The TSM predicts team effectiveness in terms of the quality of actions at the incident scene.
