From trainee to FE lecturer: trials and tribulations 1

The article draws on the findings of a longitudinal study of an opportunistic sample of full‐time further education trainee teachers attending an English new university. The study commenced in 2002 seeking to examine the processes through which trainee teachers entered the profession. Initially the research explored the routes followed and experiences that led trainees to enter teacher training. This was accompanied by an interest in trainees’ experiences in their placement colleges. The final stage of the project draws upon fieldwork conducted in 2004/05, which seeks to examine trainees’ accounts of teaching and working in the sector. This particular paper explores the lived experiences of four respondents and considers the personal trajectories that have led to FE teacher training. This is related to their orientations towards teaching and is followed by a section exploring teaching experiences within particular educational settings. Finally, the article examines respondents’ transitions to FE concluding with the significance of these accounts for the development of a progressive educational politics. It is argued these are equivocal, though respondents concern with care of their students contains progressive possibilities.
Interorganizational Linkages and Population Dynamics: Buffering and Transformational Shields.

This research was partially supported by the University of Wisconsin Graduate Fund and the University of WisconsinMadison Business School Research Fund. Helpful suggestions during the paper's evolution were provided by William Barnett, Jack Brittain, Dan Levinthal, James March, Cora Marrett, Craig Olson, Jitendra Singh, and three anonymous reviewers. The order of authorship was determined randomly. This paper examines evidence concerning the existence of organizational buffers, which insulate an organization from environmental disturbances, and transformational shields, which insulate an organization from the risk of failure due to transformation. It proposes that interorganizational linkages in particular can (1) buffer organizations from failure, (2) affect the likelihood of organizational transformation, and (3) modify the effect of organizational transformation on failure. These propositions are examined using event-history analysis of data on approximately 1,000 Finnish newspapers over a 200-year period. In this population, linkages reduced failure, increased organizational transformations, and altered the chances for failure after transformation. More generally, the findings support the existence of organizational buffers and transformational shields, suggesting further work on their role in population dynamics. '
Narrative involvement in games

This paper claims that the spirited debates about game narratives in the game industry and academia have not seen much progress due to their being too stuck in classical notions of narrative developed for non-ergodic media such as film or literature. The argument forwarded here is, therefore, that we need to re-conceptualize our notion of narrative considerably in order for the concept to be productive in the context of games. This re-conceptualization needs to take into account the cybernetic nature of games and thus factor in the experiential dimension of the human as well as the formal properties of the game. Due to length limitations the paper will focus primarily on the experiential side of the game/player equation. This dimension has, so far, presented considerable difficulties in finding a solid theoretical model upon which to be based, resulting in overly vague conceptualizations thereof. This paper builds on the Player Involvement Model described in Calleja’s In-Game:From Immersion to Incorporation, in order to arrive at a solid framework for understanding experiential narrative in games.
The Structure of Opportunity: How Promotion Ladders Vary within and among Organizations.

A previous version of this paper was presented at the 1984 Academy of Management annual meeting. The authors gratefully acknowledge research support from the National Science Foundation (SES 7924905), the CenterforAdvanced Study in the Behavioral Sciences (BNS 76-22943), and the Stanford Graduate School of Business. Teri Bush, Kelsa Duffy, and Jill Fukuhara provided splendid technical support. Howard Aldrich, Robert Althauser, Yinon Cohen, Frank Dobbin, Paul Osterman, and the ASQ reviewers and editors offered helpful comments on earlier versions of this paper. This paper analyzes data describing jobs in 100 establishments in order to test hypotheses about the characteristics of jobs and organizations associated with the structure of internal promotion ladders. The diversity of labor market arrangements found within the organizations indicates only weak support for hypotheses linking internal labor markets to organizational or sectoral imperatives. Atthe job level, however, there is support for hypotheses linking job ladders to firm-specific skills, organizational structure, gender distinctions, technology, occupational differentiation, the institutional environment, and the interests of unions. The paper concludes with an examination of how promotion ladders are formed from clusters of jobs associated with each other by occupation, skill, or gender composition.e
Can robots be teammates?: Benchmarks in human–robot teams

The team has become a popular model to organize joint human–robot behavior. Robot teammates are designed with high-levels of autonomy and well-developed coordination skills to aid humans in unpredictable environments. In this paper, we challenge the assumption that robots will succeed as teammates alongside humans. Drawing from the literature on human teams, we evaluate robots’ potential to meet the requirements of successful teammates. We argue that lacking humanlike mental models and a sense of self, robots may prove untrustworthy and will be rejected from human teams. Benchmarks for evaluating human–robot teams are included, as are guidelines for defining alternative structures for human–robot groups.
University Accreditation of Professional Development in Schools: can professional development serve two masters?

Abstract This research investigated the challenges of accrediting and gaining credit for competence–based professional development in schools. In–service teachers applied Masters–level criteria to assess qualities of intent, strategy, monitoring and evaluation in 12 portfolios completed in fulfilment of the requirements of the Northern Ireland Programme for Early Professional Development. Results indicate that teachers who attempt critical understanding of their own competence through focused enquiry and informed reflection can satisfy employer demands for self–appraisal and university accreditation requirements simultaneously. Programme constraints were, however, found to facilitate instrumental intent and shortterm, technical self–appraisal, rather than the principled enquiry and range of reflection that can achieve personal, professional and systemic change. The author argues that conflicting views of professionalism need not obstruct direct university accreditation of workplace learning. The purpose, rationality and ethical quality of policy–driven professional development activities can be extended through shared accreditation processes and the availability of clearly articulated Masters criteria.
Ribavirin suppresses eIF4E-mediated oncogenic transformation by physical mimicry of the 7-methyl guanosine mRNA cap

The eukaryotic translation initiation factor eIF4E is deregulated in many human cancers, and its overexpression in cells leads to malignant transformation. Oncogenic properties of eIF4E are directly linked to its ability to bind 7-methyl guanosine of the 5′ mRNA. Here, we observe that the antiviral guanosine analogue ribavirin binds to eIF4E with micromolar affinity at the functional site used by 7-methyl guanosine mRNA cap, competes with eIF4E:mRNA binding, and, at low micromolar concentrations, selectively disrupts eIF4E subcellular organization and transport and translation of mRNAs posttranscriptionally regulated by eIF4E, thereby reducing levels of oncogenes such as cyclin D1. Ribavirin potently suppresses eIF4E-mediated oncogenic transformation of murine cells in vitro, of tumor growth of a mouse model of eIF4E-dependent human squamous cell carcinoma in vivo, and of colony formation of eIF4E-dependent acute myelogenous leukemia cells derived from human patients. These findings describe a specific, potent, and unforeseen mechanism of action of ribavirin. Quantum mechanical and NMR structural studies offer directions for the development of derivatives with improved cytostatic and antiviral properties. In all, ribavirin's association with eIF4E may provide a pharmacologic means for the interruption of posttranscriptional networks of oncogenes that maintain and enhance neoplasia and malignancy in human cancer.
Front Interactions in a Three-Component System

The three-component reaction-diffusion system introduced in (C. P. Schenk et al., Phys. Rev. Lett., 78 (1997), pp. 3781-3784) has become a paradigm model in pattern formation. It exhibits a rich variety of dynamics of fronts, pulses, and spots. The front and pulse interactions range in type from weak, in which the localized structures interact only through their exponentially small tails, to strong interactions, in which they annihilate or collide and in which all components are far from equilibrium in the domains between the localized structures. Intermediate to these two extremes sits the semistrong interaction regime, in which the activator component of the front is near equilibrium in the intervals between adjacent fronts but both inhibitor components are far from equilibrium there, and hence their concentration profiles drive the front evolution. In this paper, we focus on dynamically evolving N -front solutions in the semistrong regime. The primary result is use of a renormalization group method to rigorously derive the system of N coupled ODEs that governs the positions of the fronts. The operators associated with the linearization about the N -front solutions have N small eigenvalues, and the N -front solutions may be decomposed into a component in the space spanned by the associated eigenfunctions and a component projected onto the complement of this space. This decomposition is carried out iteratively at a sequence of times. The former projections yield the ODEs for the front positions, while the latter projections are associated with remainders that we show stay small in a suitable norm during each iteration of the renormalization group method. Our results also help extend the application of the renormalization group method from the weak interaction regime for which it was initially developed to the semistrong interaction regime. The second set of results that we present is a detailed analysis of this system of ODEs, providing a classification of the possible front interactions in the cases of N =1 , 2, 3, 4, as well as how front solutions interact with the stationary pulse solutions studied earlier in (A. Doelman, P. van Heijster, and T. J. Kaper,J. Dynam. Differential Equations, 21 (2009), pp. 73-115; P. van Heijster, A. Doelman, and T. J. Kaper, Phys. D, 237 (2008), pp. 3335-3368). Moreover, we present some results on the general case of N -front interactions.
Lying, in a manner of speaking

We investigated the production and perception of paralinguistic cues to deception in a two-person, interactive game. Speakers tried to mislead their partner by lying some of the time, while listeners tried to catch speakers out by guessing when they were lying. Our results show that listeners were more likely to associate disfluencies with deception, despite the fact that speakers were in fact more disfluent when telling the truth. We interpret this pattern of behavior within the attempted control approach to deception, whereby liars manipulate their language to conceal the fact that they are lying.
Power Reduction Techniques for LDPC Decoders

This paper investigates VLSI architectures for low-density parity-check (LDPC) decoders amenable to low-voltage and low-power operation. First, a highly-parallel decoder architecture with low routing overhead is described. Second, we propose an efficient method to detect early convergence of the iterative decoder and terminate the computations, thereby reducing dynamic power. We report on a bit-serial fully-parallel LDPC decoder fabricated in a 0.13-mum CMOS process and show how the above techniques affect the power consumption. With early termination, the prototype is capable of decoding with 10.4 pJ/bit/iteration, while performing within 3 dB of the Shannon limit at a BER of 10-5 and with 3.3 Gb/s total throughput. If operated from a 0.6 V supply, the energy consumption can be further reduced to 2.7 pJ/bit/iteration while maintaining a total throughput of 648 Mb/s, due to the highly-parallel architecture. To demonstrate the applicability of the proposed architecture for longer codes, we also report on a bit-serial fully-parallel decoder for the (2048, 1723) LDPC code in 10 GBase-T standard synthesized with a 90-nm CMOS library.
Mitigation of simultaneous switching noise on EBG planes using firefly algorithm

In this paper, a meta-heuristic optimization algorithm is proposed for the design of Electromagnetic Band Gap (EBG) structures to suppress simultaneous switching noise (SSN) on printed circuit boards. This algorithm offers optimized dimensions of EBG unit cell at desired frequency band. A design example of 2D planar EBG structure in the specified frequency band is presented. The simulated results are found to be in good agreement with the analytical results.
CloRoFor: Cloud Robust Forensics

The malicious alteration of machine time is a big challenge in computer forensics. Detecting such changes and reconstructing the actual timeline of events is of paramount importance. However, this can be difficult since the attacker has many opportunities and means to hide such changes. In particular, cloud computing, host and guest machine time can be manipulated in various ways by an attacker. Guest virtual machines are especially vulnerable to attacks coming from their (more privileged) host. As such, it is important to guarantee the timeline integrity of both hosts and guests in a cloud, or at least to ensure that the alteration of such timeline does not go undetected. In this paper we survey the issues related to host and guest machine time integrity in the cloud. Further, we describe a novel architecture for host and guest time alteration detection and correction/resilience with respect to compromised hosts and guests. The proposed framework has been implemented on an especially built simulator. Collected results are evaluated and discussed. Performance figures show the feasibility of our proposal.
RD2: Resilient Dynamic Desynchronization for TDMA over Lossy Networks

We present a distributed TDMA negotiation approach for single-hop ad-hoc network communication. It is distributed, resilient to arbitrary transient packet loss and defines a non-overlapping TDMA schedule without the need of global time synchronization. A participating node can dynamically request a fraction of the static TDMA period T. It will receive its fraction if enough time resources are available. In any case, every node can request and will receive at least a fair fraction of size 1/N. Due to its resilience to arbitrary transient packet loss, the algorithm is well suited for lossy networks like found in wireless communications. Our approach is designed to work in highly dynamic scenarios efficiently. We will show, that it defines a dynamic non-overlapping TDMA schedule even at high packet loss rates. The performance of the TDMA negotiation is analyzed by simulation and compared to results of related work.
Delayed Muscle Soreness and Cytoskeletal Alterations: An Immunocytological Study in Man

Delayed muscle soreness in man is known to be attributed to a disorganization of the myofibrils. Our aim in the present study was to investigate whether the intermediate filament system is affected as well. Biopsies were taken from the right m. vastus lateralis of six males (aged 23 +/- 3 years) suffering from severe post-exercise soreness of their thigh muscles. Intermediate filament protein was visualized by indirect immunofluorescence microscopy using an antibody specific to desmin. A typical finding in biopsies taken 3 days after exercise was abundant longitudinal "desmin" extensions. Moreover, strongly autofluorescent granules were observed beneath the sarcolemma. It is concluded that muscles subjected to unusual exercise contain myofibrillar and cytoskeletal disturbances accompanied by increased lysosomal activity.
Operator binding, gaps, and pronouns

Variables are null elements with operator antecedents in nonargument positions. In some languages, a pronoun may also be variable-bound in Sstructure, as a subcase of WH movement in the derivation of S-structure. A set of structures in Hindi-Urdu has the surface appearance of a gap or resumptive pronoun variable-bound by an antecedent in a higher clause. This language has WH in situ question and relative phrases as the most usual option, with WH movement in the derivation of logical form, not S-structure. The latter in situ structures are subject to a version of the empty category principle based on government projections and directionality of government, while the apparent cases of W H movement in the syntax are not. Instead, they are subject to very specific restrictions on case, thematic role, and subcategorization of the matrix verb and are restricted to multiclausal sentences. It is proposed that the matrix-clause WH antecedent is an internal operator topic, like French dont, coindexed with a pronoun, lexical or null, in a subordinate clause. Some implications are discussed for the place of resumptive pronouns in universal grammar (Sells 1984) and for the status of pronouns and gaps in S-structure as evidence for WH movement.
Summary of Team IHMC's virtual robotics challenge entry

This paper presents a high level overview of the work done by Team IHMC (Florida Institute for Human and Machine Cognition) to win the DARPA Virtual Robotics Challenge (VRC), held June 18-20 2013. The VRC consisted of a series of three tasks (driving a vehicle, walking over varied terrain, and manipulating a fire hose), to be completed in simulation using a model of the humanoid robot Atlas. Team IHMC was able to complete all of these challenges multiple times during the competition. The paper presents our approach, as well as a bird's-eye view of the major software components and their integration.
The education crisis in South Africa: Restructuring the policy discourse

This paper examines three key education policy reports which emerged during the public debate over the ‘education crisis’ in South Africa in the early 1980s. The paper argues that the rhetoric of crisis and these particular discourses must be seen as part of the general restructuring of ideological discourse accompanying the process of state reconstruction necessitated by the escalating class struggle and challenges to continued capital accumulation which became particularly apparent in the late 1970s and early 1980s. The discourses reflect both the search for a new reformist consensus on education policy and the conflicts within the state over the most appropriate form of this consensus. The decline of the public debate over education policy suggests that these discourses have been successful in eliciting some consent for limited reformism among the audiences at whom they were directed. And accordingly, public attention has moved on to other conjunctual aspects of the process of state reconstruction ‐ su.
ATP synthase subunit alpha and LV mass in ischaemic human hearts

Mitochondrial dysfunction plays a critical role in the development of ischaemic cardiomyopathy (ICM). In this study, the mitochondrial proteome in the cardiac tissue of ICM patients was analysed by quantitative differential electrophoresis (2D‐DIGE) and mass spectrometry (MS) for the first time to provide new insights into cardiac dysfunction in this cardiomyopathy. We isolated mitochondria from LV samples of explanted hearts of ICM patients (n = 8) and control donors (n = 8) and used a proteomic approach to investigate the variations in mitochondrial protein expression. We found that most of the altered proteins were involved in cardiac energy metabolism (82%). We focused on ATPA, which is involved in energy production, and dihydrolipoyl dehydrogenase, implicated in substrate utilization, and observed that these molecules were overexpressed and that the changes detected in the processes mediated by these proteins were closely related. Notably, we found that ATPA overexpression was associated with reduction in LV mass (r = −0.74, P < 0.01). We also found a substantial increase in the expression of elongation factor Tu, a molecule implicated in protein synthesis, and PRDX3, involved in the stress response. All of these changes were validated using classical techniques and by using novel and precise selected reaction monitoring analysis and an RNA sequencing approach, with the total heart samples being increased to 24. This study provides key insights that enhance our understanding of the cellular mechanisms related to the pathophysiology of ICM and could lead to the development of aetiology‐specific heart failure therapies. ATPA could serve as a molecular target suitable for new therapeutic interventions.
Models for the Diffusion of Beliefs in Social Networks: An Overview

Our article compared models for social learning and opinion diffusion in the context of economics and social science with those used in signal processing over networks of sensors, explaining how learning emerges or fails to emerge in both scenarios. It also critically discusses how the advent of the Internet and of smartphones is generating a wealth of data and enhancing the decision-making capabilities of social agents in ways that were never conceivable before. The article also argues that more engineering research is needed to advance modeling and inference algorithms and enhance even further the cyberinteractions of social agents. This area has tremendous potential as well as carries tremendous risks. Consumers lose their privacy and can be influenced in undesired ways. Hence, a critical consideration to make in expanding our understanding on this subject is to what extent it is safe to increase the ability of hardware and software to capture contextual data about the customers.
A variational framework for active and adaptative segmentation of vector valued images

Much effort has been made in integrating different information in a variational framework to segment images. Recent works on curve propagation were able to incorporate stochastic information (see Paragios, N. and Deriche, R., J. Visual Commun. and Image Representation, 2002; Zhu, S. and Yuille, A., 1996) and prior knowledge on shapes (see Cremers, D. et al., 2002; Rousson M. and Paragios, N., 2002). The information inserted in these studies is most of the time extracted offline. Meanwhile, other approaches have proposed to extract region information during the segmentation process itself (see Chan, T. et al., 2000; Jehan-Besson, S. et al., 2002; Yezzi, A. et al., 1999). Following these new approaches and extending the work of Paragios and Deriche to vector-valued images, we propose an entirely variational framework to approach the segmentation problem. Both the image partition and the statistical parameters for each region are unknown. After a brief reminder on recent segmenting methods, we present a variational formulation obtained from a Bayesian model. After that, we show two different differentiations driving to the same evolution equations. Detailed studies on gray and color images of the 2-phase case follow. We finish with an application to tracking which shows the benefits of our dynamic framework.
