Reflection in Medical Education

This paper offers a medical-education perspective that I will hope complement other disciplinary perspectives in examining the value of reflection for learning in tertiary education. The paper outlines some of the theoretical strands of reflective practice facilitated in a unique course subject for professionalism and patient safety, within the new spiral curriculum at Leeds University School of Medicine. The material presented in this paper outlines some of what is delivered during the medical students’ interactive sessions; this material is continually modified based on feedback from both students and learning facilitators. The paper discusses why both students and clinicians need to reflect, some of the theoretical dimensions and models and examples from the Leeds context of how reflective competence can be progressively developed over the course of an undergraduate program. The focus of the final section suggests directions for reflective practice in the future, where reflexivity takes the form of more collective endeavours requiring some change in culture and perceptions of professional identity. The paper concludes with the proposition that collaborative forms of reflection need to include more involvement of patients, interprofessional communities of practice and the use of learning from other disciplines; all of these require different levels of thinking and different ways of working.

Ipb-frame adaptive mapping mechanism for video transmission over IEEE 802.11e WLANs

This paper proposed an IPB-frame Adaptive Mapping Mechanism (AMM) to improve the video transmission quality over IEEE 802.11e Wireless Local Area Networks (WLANs). Based on the frame structure of hierarchical coding technology, the probability of each frame allocated to the most appropriate Access Category (AC) was dynamically updated according to its importance and traffic load of each AC. Simulation results showed the superior performance of the proposed AMM by comparing with three other existing mechanisms in terms of three objective metrics.
Endothelial Sodium Channels Trigger Endothelial Salt Sensitivity With Aging

The epithelial sodium channel is also expressed in vascular endothelium (endothelial sodium channel [EnNaC]). Depending on ambient sodium concentration, EnNaC is associated with mechanical stiffening of the endothelial cell cortex, leading to endothelial dysfunction. Because the incidence of both salt sensitivity and endothelial dysfunction increases with age, we investigated the abundance of EnNaC in aging mice. To assess EnNaC functionality and endothelial salt sensitivity, stiffness was measured while ambient sodium was varied. Aortae of young (3 months) and old (15 months) C57BL/6J wild-type mice were kept ex vivo on a physiological concentration of aldosterone (0.45 nmol/L). Spironolactone (10 nmol/L) and amiloride (1 &mgr;mol/L) were applied for aldosterone antagonism and EnNaC blockage, respectively. EnNaC at the endothelial cell surface was quantified by immunofluorescence staining. Cortical stiffness was monitored by atomic force microscopy when ambient sodium was raised from 135 to 150 mmol/L. In ex vivo aortae of older mice, endothelial cells had significantly higher EnNaC numbers than those of younger mice (+23%). In parallel, cortical stiffness was found increased (+8.5%). Acute application of high sodium led to an immediate rise in stiffness in both groups but was pronounced in endothelium of older mice (+18% versus +26%). Spironolactone and amiloride lowered EnNaC abundance and prevented endothelial stiffening under all conditions. We conclude that EnNaC mediates endothelial salt sensitivity in the aging process. This mechanism might contribute to the development of age-related cardiovascular disease and suggests the usage of spironolactone and amiloride specifically in the elderly.
Cooperation and Routing in Multi-Hop Networks

We study the cross-layer problem of combining routing and cooperative diversity in multi-hop, bandwidth- constrained networks with dedicated multiple access. Previous work in cooperative diversity nearly always assumes cooperation to be a positive. We show that in a large scale multi-hop network, cooperation must only be used selectively. Our figure of merit is achievable data rate between a source and destination at a fixed probability of outage. We show that enforcing multiple hops is detrimental to performance, since each extra hop requires bandwidth expansion. This performance can be significantly improved by incorporating a selective cooperative diversity scheme on a one-hop link. On the other hand, the simulation results show that cooperative diversity does not improve performance over a dynamic routing protocol which searches for the optimal, non-diversity, route. Including the search for cooperative nodes into the dynamic route search, however, does further increase flow rates by decreasing the average number of hops and thus decreasing the required bandwidth expansion. This paper therefore points to the importance of an integrated approach to routing and the physical layer in cooperative networks.
Intrusion Detection Using Hierarchical Clustering Followed By Signature Approach & Random Forest Classifier

As the need of technology is expanded, intrusion revelation has become an emerging campus for analysis. Intrusion Detection System (IDS) tries to recognize as well as announce the action of applicants as either normal or anomaly. An IDS is not only a nonlinear but also complicated dilemma. It pledges with network traffic data. Many IDS approaches have been introduced. It produces different layers of accuracy. Due to which evolution of adequate as well as vigorous Intrusion detection system is required. The consequence display that planned miniature is potent with immense detection rate. In this paper, we have constructed a model for intrusion detection system using hierarchical clustering followed by signature based approach and random forest algorithm.
Eukaryotic Richness in the Abyss: Insights from Pyrotag Sequencing

Background The deep sea floor is considered one of the most diverse ecosystems on Earth. Recent environmental DNA surveys based on clone libraries of rRNA genes confirm this observation and reveal a high diversity of eukaryotes present in deep-sea sediment samples. However, environmental clone-library surveys yield only a modest number of sequences with which to evaluate the diversity of abyssal eukaryotes. Methodology/Principal Findings Here, we examined the richness of eukaryotic DNA in deep Arctic and Southern Ocean samples using massively parallel sequencing of the 18S ribosomal RNA (rRNA) V9 hypervariable region. In very small volumes of sediments, ranging from 0.35 to 0.7 g, we recovered up to 7,499 unique sequences per sample. By clustering sequences having up to 3 differences, we observed from 942 to 1756 Operational Taxonomic Units (OTUs) per sample. Taxonomic analyses of these OTUs showed that DNA of all major groups of eukaryotes is represented at the deep-sea floor. The dinoflagellates, cercozoans, ciliates, and euglenozoans predominate, contributing to 17%, 16%, 10%, and 8% of all assigned OTUs, respectively. Interestingly, many sequences represent photosynthetic taxa or are similar to those reported from the environmental surveys of surface waters. Moreover, each sample contained from 31 to 71 different metazoan OTUs despite the small sample volume collected. This indicates that a significant faction of the eukaryotic DNA sequences likely do not belong to living organisms, but represent either free, extracellular DNA or remains and resting stages of planktonic species. Conclusions/Significance In view of our study, the deep-sea floor appears as a global DNA repository, which preserves genetic information about organisms living in the sediment, as well as in the water column above it. This information can be used for future monitoring of past and present environmental changes.
Interpreting sulci on hominin endocasts: old hypotheses and new findings

Paleoneurologists analyze internal casts (endocasts) of fossilized braincases, which provide information about the size, shape and, to a limited degree, sulcal patterns reproduced from impressions left by the surface of the brain. When interpreted in light of comparative data from the brains of living apes and humans, sulcal patterns reproduced on hominin endocasts provide important information for studying the evolution of the cerebral cortex and cognition in human ancestors. Here, new evidence is discussed for the evolution of sulcal patterns associated with cortical reorganization in three parts of the hominin brain: (1) the parietotemporo-occipital association cortex, (2) Broca's speech area, and (3) dorsolateral prefrontal association cortex. Of the three regions, the evidence regarding the last is the clearest. Compared to great apes, Australopithecus endocasts reproduce a clear middle frontal sulcus in the dorsolateral prefrontal cortex that is derived toward the human condition. This finding is consistent with data from comparative cytoarchitectural studies of ape and human brains as well as shape analyses of australopithecine endocasts. The comparative and direct evidence for all three regions suggests that hominin brain reorganization was underway by at least the time of Australopithecus africanus (~2.5 to 3.0 mya), despite the ape-sized brains of these hominins, and that it entailed expansion of both rostral and caudal association cortices.
Delay-optimal data transmission in renewable energy aided cognitive radio networks

Renewable energy powered cognitive radio (CR) network has gained much attention due to its combination of the CR's spectrum efficiency and the renewable energy's “green” nature. In the paper, we investigate the delay-optimal data transmission in the renewable energy aided CR networks. Specifically, a primary user (PU) and a secondary user (SU) share the same frequency in an area. The SU's interference to the PU is controlled by interference-signal-ratio (ISR) constraint, which means that the ISR at the PU receiver (Rx) should be less than a threshold. Under this constraint, the renewable energy powered SU aims to minimize the average data buffer delay by scheduling the renewable allocations in each slot. A constrained stochastic optimization problem is formulated when the randomness of the renewable arrival, the uncertainty of the SU's data generation, and the variability of the fading channel are taken into account. By analyzing the formulated problem, we propose two practical algorithms that is optimal for two special scenarios. And the two algorithms respectively give an upper and a lower bound for the general scenario. In addition, the availability of the PU's private information at the SU is discussed. Finally, numerical simulations verify the effectiveness of the proposed algorithm.
Time and Temporary Migration: The Case of Temporary Graduate Workers and Working Holiday Makers in Australia

This article provides an analysis of ‘being temporary’ in the context of two forms of migration that are of increasing significance to Australia: temporary graduate workers (TGWs) and working holiday makers (WHMs). Recent policy changes to these visa categories allow for extended periods of work and residence in Australia, primarily among young people who are seeking an overseas work/life experience or a pathway to more permanent migration. The article brings the various temporal dimensions of these migration processes to the fore, asking how time functions as both a disciplinary practice of the state and as part of the life and labour experiences of migrants. In doing so, it problematises the idea of temporariness as both a normative constraint and a qualitative experience in a national context in which paradigms of permanent settlement and full citizenship continue to dominate discursive constructions of migration. It creates a framework for understanding the key temporal aspects of TGW and WHM migration processes: temporal eligibility and migrant subjectivities; temporal constraints and differential inclusion; and the contingent boundaries around temporariness, extended temporariness and permanence. This has salience for continued understandings of emerging forms of temporary migration in wider contexts.
Efficient Pre-copy Live Migration with Memory Compaction and Adaptive VM Downtime Control

Virtual machine (VM) live migration is an important feature of the virtualization technique. Pre-copy method is typically used to support live migration in most virtualization environments. It is observed that pre-copy may not work in some situation where memory-intensive applications are running in KVM. Moreover, pre-copy live migration does not consider high duplication ratio between memory and root file system as well as between memory snapshots. This paper proposes two techniques to improve pre-copy live migrations: 1) memory compaction technique based on disk cache and memory snapshot, 2) adaptive downtime control scheme based on the history of VM's memory update information called WWS (Writable Working Set). We have successfully implemented the proposed method in KVM. It is shown that the proposed method can support live migration under any circumstances with little overhead.
A Democratic Conception of Privacy

Carol Pateman has said that the public/private distinction is what feminism is all about. I tend to be skeptical about categorical pronouncements of this sort, but this book is a work of feminist political philosophy and the public/private distinction is what it is all about. It is motivated by the belief that we lack a philosophical conception of privacy suitable for a democracy; that feminism has exposed this lack; and that by combining feminist analysis with recent developments in political philosophy, we can meet the philosophical and political need for a distinctively democratic conception of privacy.This book then, is an effort to sketch and defend such a conception of privacy. It aims to show that while some conceptions of privacy are inconsistent with democracy, others are not. Indeed, the book asserts, the belief that privacy can be valuable and that it can justify basic legal rights, is implicit in a democratic conception of persons as free and equal beings, and a democratic conception of politics as the self-governing, or regulating, activity of such individuals. Just as we can and should reject undemocratic conceptions of the suffrage in favour of democratic ones, so the book maintains, we can and must reject undemocratic conceptions of privacy in favour of ones that reflect the moral equality of men and women.
Rescaling Environmental Governance: Watersheds as Boundary Objects at the Intersection of Science, Neoliberalism, and Participation

This paper is concerned with the rescaling of environmental governance, and with the social construction of environmental and governance scales in particular. With the aid of case-study data from Canada, it is argued that watersheds, as particular forms of rescaled environmental governance, have increased in popularity because of their status as boundary objects: that is, a common concept interpreted differently by different groups. The paper shows how particular features of the watershed approach—namely, their physical size and the shared discursive framings they employ (‘stakeholder’ and ‘integration’)—make the watershed concept both cohesive enough to travel among different epistemic communities, and plastic enough to be interpreted and used differently within them. As such, it is suggested that the trend of the uptake of the so-called ‘watershed approach’ reflects and is shaped by ideologies underpinned by three different, and occasionally competing, epistemic communities: the scientific, neoliberal, and grassroots communities. These arguments corroborate constructivist accounts of the political nature of boundary drawing, bring science into discussion on the relationship between neoliberalism and public participation, and contribute to environmental governance literatures by providing an alternative explanation for the uptake of watersheds in recent decades.
Functional recovery despite prolonged bilateral loss of somatosensory evoked potentials: report on two patients

A bilateral loss of short latency somatosensory evoked potentials (SSEPs) after head trauma or non-traumatic brain damage is normally associated with a deleterious neurological outcome. An adequate recovery in reported in two deeply comatose patients with head trauma or severe hypertensive encephalopathy despite prolonged bilateral loss of SSEPs over days, found in repeated recordings. Hence, a bilateral loss of SSEPs should not be considered alone for prediction of outcome in cerebral injury.
An interference-aware distributed transmission technique for dense small cell networks

An ultra-dense deployment of small cells with multi-antenna nodes is expected to be the solution for coping with the huge traffic growth expected in near future. Mutual interference among coexisting users is one of the main performance bottlenecks in such dense deployment scenarios. A distributed transmission technique that can efficiently manage the interference in an uncoordinated dense small cell network is investigated in this work. The proposed interference aware scheme only requires instantaneous channel state information at the transmitter end towards the desired receiver. Motivated by penalty methods in optimisation studies, an interference dependent weighting factor is introduced to control the number of parallel transmission streams. The proposed scheme can outperform a more complex benchmark precoding scheme in terms of the sum network throughput in certain scenarios and with realistic channel estimation errors, while delivering close to the benchmark performance under general conditions.
Teachers’ Stances and Practical Arguments Regarding a Science‐Indigenous Knowledge Curriculum: Part 1

The new South African curriculum known as Curriculum 2005 (to depict the year of its full implementation) requires that teachers integrate school science with Indigenous Knowledge Systems (IKS). Curriculum 2005 has generated heated debates at various levels since its inception in 1997. This study focuses on the effectiveness or otherwise of a Practical Argumentation Course (PAC) as an instructional tool for enhancing teachers’ understanding of, and ability to implement, a Science‐IKS curriculum. Data collected by questionnaires, video‐taped and audio‐taped interviews, and reflective essays were analysed in terms of a Practical Argumentation Framework developed for the purpose. The findings show that the PAC did enhance the teachers’ understanding as well as increase their awareness of the need to implement a Science‐IKS curriculum in their classrooms. Also, the PAC seemed to have made the teachers more sceptical of the notion that science is the only way of knowing or interpreting experience, or that IKS were based on superstitious beliefs. All the teachers recommended the need to include the PAC or similar courses in science teacher education programmes.
The Evolution of Consciousness

as a "done deaL" This is, of course, absurd, but Gazzaniga is so given to such hyperbole that he may believe it. One more example of his excess: it turns out that Immanuel Kant may have had a parietal lobe tumor, affecting language ability and the ability of the emotional system to cue good cognitive strategies. In typical fashion, Gazzaniga writes, "Is it possible that Kantians have saluted a man who was writing nonsense-a philosophy for those who do not have a normal cognitive and emotional system? " (p. 121). Professor, please. In sum, this book contains some interesting information about the brain. As a neuropsychological theory of human consciousness or the sense of self, it does not approach the depth and complexity of, for example, Damasio's most recent effort (1999). The book alludes to some fascinating and conceptually fundamental debates in cognitive neuroscience. Unfortunately, Professor Gazzaniga does not give these debates the balanced analysis they deserve.
Difference in the dynamic properties of chiral and racemic crystals of serine studied by Raman spectroscopy at 3-295 K.

Single-crystal polarized Raman spectra (60-4000 cm(-1) at 3 < or = T < or = 295 K) were measured for chiral L- and racemic DL-serine, alpha-amino-beta-hydroxypropionic acid, (NH3)+CH(CH2OH)(COO)-. The Raman spectra of dl-serine do not show any striking changes with temperature or on storage. In contrast to that, the dynamical properties of L-serine change at about 140 K. These changes can be interpreted as the reorientation of the side chain -CH2OH fragments of the zwitterions with respect to the backbone C-C bonds, resulting in the positional disorder of the O-H.O intermolecular H-bonds. The redistribution in the intensities of the Raman spectra of the crystals of L-serine stored for a long time (about a year) indicates the changes in the orientation of the molecular fragments in the direction normal to the axes of the head-to-tail chains. The difference in the thermodynamic functions of L- and DL-serine reported previously [Drebushchak, V. A. ; Kovalevskaya, Yu. A. ; Paukov, I. E. ; Boldyreva, E. V. J. Therm. Anal. Calorim. 2007, 89 (2), 649-654] is explained by the difference in the spectra of external vibrations of the crystals.
A Subaru Search for Lyα Blobs in and around the Protocluster Region At Redshift z = 3.1

We report the properties of 35 robust candidate Lyα blobs (LABs), which are larger than 16 arcsec2 in isophotal area and brighter than 0.7 × 10-16 ergs s-1 cm-2, located in and around the protocluster region at redshift z = 3.1 discovered by Steidel et al. in the SSA22 field, based on wide-field (31′ × 23′) and deep narrowband (NB497; 4977 Å, FWHM 77 Å) and broadband (B, V, and R) images taken with the prime-focus camera on the Subaru Telescope. The two previously known giant LABs are the most luminous and the largest in our survey volume of 1.3 × 105 Mpc3. We reveal the internal structures of the two giant LABs and discover some bubble-like features, which suggest that intensive starburst and galactic superwind phenomena occurred in these objects in the past. The other 33 LABs have isophotal areas of ∼16–78 arcsec2 and flux of (0.7–7) × 10-16 ergs s-1 cm-2. These 35 LABs show a continuous distribution of isophotal area and emission-line flux. The distributions of average surface brightness and morphology are widespread from relatively compact high surface brightness objects to very diffuse low surface brightness ones. The physical origins of these LABs may be (1) photoionization by massive stars or active galactic nuclei, or (2) cooling radiation from gravitationally heated gas, or (3) shock heating by starburst-driven galactic superwind. One-third of the LABs are apparently not associated with ultraviolet continuum sources that are bright enough to produce Lyα emission, assuming a Salpeter initial mass function. Of these LABs 90% are located inside the high surface density region of the 283 relatively compact and strong Lyα emitters selected in our previous study. This suggests that these LABs may be phenomena related to a dense environment at high redshift.
