Flexibility, reflexivity and reflection in the contemporary workplace

Within contemporary changes there is an increased reflexivity wherein social formations, organizations and individuals are required to change, to learn to change, and change to learn. Lifelong learning has become central to education and economic policy, with an increased emphasis on individuals, workplaces and providers of learning opportunities becoming more flexible. This article explores some of the evidence for the emergence of different workplace practices and identities in response to and as part of the development of reflexive modernization and the significance of pedagogies of reflection in these changes. It suggests that pedagogies of reflection are integral to reflexive modernization, flexible lifelong learners and changes in the workplace.
The rapid generation of mutation data matrices from protein sequences

An efficient means for generating mutation data matrices from large numbers of protein sequences is presented here. By means of an approximate peptide-based sequence comparison algorithm, the set sequences are clustered at the 85% identity level. The closest relating pairs of sequences are aligned, and observed amino acid exchanges tallied in a matrix. The raw mutation frequency matrix is processed in a similar way to that described by Dayhoff et al. (1978), and so the resulting matrices may be easily used in current sequence analysis applications, in place of the standard mutation data matrices, which have not been updated for 13 years. The method is fast enough to process the entire SWISS-PROT databank in 20 h on a Sun SPARCstation 1, and is fast enough to generate a matrix from a specific family or class of proteins in minutes. Differences observed between our 250 PAM mutation data matrix and the matrix calculated by Dayhoff et al. are briefly discussed.
"Coherence radar" and "spectral radar"-new tools for dermatological diagnosis.

"Coherence radar," an optical 3-D sensor based on short coherence interferometry, is used to measure skin surface topology. This method is called optical coherence profilometry (OCP) and it may be a useful tool for medical diagnosis in dermatology because different medical conditions show distinct alterations of the skin surface. The measuring uncertainty is less than 2 μm. The measuring time is about 4 s. in vivo 3-D mapping of naked skin was performed without preparation. For clinical application, a fiber optical implementation was introduced. Spectral radar is an optical sensor for the acquisition of skin morphology based on OCT techniques. The scattering amplitude a(z) along one vertical axis from the surface into the bulk can be measured within one exposure. No reference arm scanning is necessary. The theory of the sensor, including the dynamic range, is discussed and in vivo measurements of human skin by a fiber optical implementation of the sensor are demonstrated. © 1998 Society of Photo-Optical Instrumentation Engineers.
Impact of CQI feedback rate/delay on scheduling video streaming services in LTE downlink

The major attraction of the next generation wireless systems such as the third generation partnership project (3GPP) Long Term Evolution (LTE) is the availability of high data-rate video services at high user velocities. However, it is quite a challenge to provide the required level of quality of service (QoS) and maintain the planned system performance due to limited radio resources, unreliable radio propagation channel and high user demands. This paper analyses the impact of channel quality indicator (CQI) delay and its aperiodic reporting rate on the performance of a well known scheduling algorithm serving video streaming users at different velocities. The analysis will be compared against the system having perfect and delayed channel knowledge at each scheduling instance. We then recommend the minimum rate requirement of aperiodic CQI reports to maintain the required QoS for a certain number of video streaming users.
Daydreaming and Mental Health

This study examined the relationship between self ratings of recorded daydreams and mental health as measured by the Mental Health Index (MHI). Forty-eight subjects recorded at least five daydreams over a two-week period and completed the MHI. As predicted there was no relationship between the MHI and subjects' rating of how they felt during the daydream. After the daydream, distressed subjects rated the daydream as being more potent than healthy subjects. Consistent with the study's hypothesis, the difference score between the two daydream ratings was related to the MHI with measures of mental health positively related to change scores and measures of distress negatively related to change scores. Results were interpreted in terms of the role of daydreams in feedback loops and self-efficacy.
Virtually real emotions and the paradox of fiction: Implications for the use of virtual environments in psychological research

Many of the psychological studies carried out within virtual environments are motivated by the idea that virtual research findings are generalizable to the non-virtual world. This idea is vulnerable to the paradox of fiction, which questions whether it is possible to express genuine emotion toward a character (or event) known to be fictitious. As many of these virtual studies are designed to elicit, broadly speaking, emotional responses through interactions with fictional characters (avatars) or objects/places, the issue raised by the paradox seems particularly apt. This paper assesses the extent to which the paradox of fiction constitutes a legitimate challenge to psychological research within virtual environments, and argues that any alleged conflict is in fact a product of an overly simplistic view of emotions which a more complete understanding resolves. Moreover, through a more detailed analysis of why the paradox cannot be sustained, one finds justification for the claim that emotions elicited through interactions with virtual (fictitious) objects/events are valid. However, their generalizability to the non-virtual world must still be treated with caution.
Properties of the resolvent of a linear Abel integral equation: implications for a complementary fractional equation

New and known properties of the resolvent of the kernel of linear Abel integral equations of the form x(t) = f (t)− λ ∫ t 0 (t− s)q−1x(s) ds, (Aλ) where λ > 0 and q ∈ (0, 1), are assembled and derived here. First, a priori bounds on potential solutions of the resolvent equation R(t) = λtq−1 − λ ∫ t 0 (t− s)q−1R(s) ds (Rλ) are obtained. Second, it is proven—using these bounds, Banach’s contraction mapping principle, new continuation and translation results, and Schaefer’s fixed point theorem—that (Rλ) has a unique continuous solution on (0, ∞), which is called the resolvent in the literature and denoted here by R(t). Third, both known and new properties of R(t) are derived. Fourth, R(t) is shown to be completely monotone and the unique continuous solution of the initial value problem of fractional order q: Dqx(t) = −λΓ(q)x(t), lim t→0+ t1−qx(t) = λ, (Iλ) where Dq denotes the Riemann–Liouville fractional differential operator. Finally, the resolvent integral function ∫ t 0 R(s) ds is shown to be the unique continuous solution of an integral equation closely related to (Rλ). Closed-form expressions for it and R(t) are derived.
Promoting Inquiry Through Science Reflective Journal Writing

The purpose of this research paper is to detail how reflective journal writing can be used to facilitate science students’ curiosity and engagement in laboratory work. This study advocates reflective journal writing as an instructional tool and a student-created learning resource that can serve additional formative assessment purposes. The researchers tracked a single teacher and his class over a period of five weeks and documented the changes that occurred when reflective journal writing was used to supplement the teaching and learning of specific curriculum items (the usage of scientific equipment and the particulate nature of matter). Findings presented show that the number and quality of students’ questions rose over time. While the number of research studies carried out with inquiry as the focus is plentiful, this paper outlines a generative strategy to enhance questioning which constitutes the essential first step in any inquiry process for any particular science content area.
Maternal Psychological Control and Peer Victimization in Early Adolescence

Guided by the family relational schema model, the current study examined the direct and indirect contributions of maternal psychological control to subsequent relational and overt peer victimization, via early adolescents’ conduct problems, fear of negative evaluation, and depressive symptoms. Participants were 499 10- to 14-year-olds (53% female; 77% European American) involved in two waves of a study with 1 year between each wave. Path analyses indicated that depressive symptoms mediated the associations between maternal psychological control and increases in both forms of peer victimization across the 1-year time period. Although conduct problems were concurrently associated with maternal psychological control, and fear of negative evaluation predicted change in both forms of peer victimization, neither variable mediated the maternal psychological control-peer victimization associations. Results were generally consistent across gender, with a few notable differences. Study findings provide partial support for the family relational schema model and implications are discussed.
Investigations on the association between normal tension glaucoma and single nucleotide polymorphisms of the endothelin-1 and endothelin receptor genes.

PURPOSE In normal tension glaucoma (NTG), intraocular pressure is within normal the range; thus, some mechanism other than increased pressure contributes to the optic neuropathy. Endothelin may be an important contributor to the development of the optic neuropathy characteristic of glaucoma. We investigated whether polymorphisms of the endothelin-1, endothelin receptor type A, and endothelin receptor type B genes were associated with NTG. METHODS Sixty-seven Korean NTG patients and 100 healthy Korean subjects were enrolled. DNA from peripheral blood leukocytes was extracted and genotype distributions of six polymorphisms in genes encoding endothelin-1 (EDN1:c.-131dupA, EDN1:c.594G > T), endothelin receptor type A (EDNRA:c.-231G > A, EDNRA:c.*70C > G, EDNRA:c.*1222C > T), and endothelin receptor type B (EDNRB:c.831A > G) were determined. Genotype and allele distributions were compared between patients and controls. In NTG subjects, untreated baseline intraocular pressure and age at the time of diagnosis, as well as the mean deviation and pattern standard deviation values of automated static perimetry were examined for an association with these genetic polymorphisms. RESULTS The polymorphism of EDNRA:c. *1222C > T was significantly associated with NTG (p = 0.028, OR = 3.33, 95% CI 1.05-10.24). In addition, the AA genotype of the EDNRA:c. -231G > A polymorphism was associated with a lower baseline intraocular pressure than in the GG+GA genotype group (14.0 +/- 2.8 mm Hg versus 16.2 +/- 2.3 mm Hg, p = 0.047). No polymorphism was associated with visual field parameters. CONCLUSIONS A polymorphism of the endothelin receptor type A gene is associated with NTG.
The effects of musical and voice “fit” on responses to advertisements

Research on musical “fit” suggests that listeners might recall more of a radio advertisement if it features musical/voice content that corresponds with features of the advertised brand. This is because the music/voice should prime certain aspects of listeners’ knowledge. Two studies were carried out to test this, each involving 5 specially prepared radio ads. The first indicated that musical fit enhanced recall of the products advertised, the brands advertised, and specific claims made during the course of the ad copy; and also participants’ ratings of liking for the ad and likelihood of purchasing the advertised product. A second similar study considered voice fit and found that this could also promote recall of specific product claims and lead to higher ratings of liking for the ad and likelihood of purchasing the advertised product. These results confirm that both musical and voice fit can prime certain aspects of listeners’ knowledge and also increase liking for ads, such that it might improve knowledge-based and affective responses to advertising. The theoretical implications of this are discussed in terms of the concept of involvement and what precisely is meant by musical/voice fit.
Coping Behaviors as Predictors of Drinking Practices among Primary in-Home Dementia Caregivers

This study examines the predictive value of coping behaviors in discriminating drinkers from nondrinkers among 109 primary in-home dementia caregivers. The participants were enrolled in a caregivers education project and completed comprehensive health and psychosocial assessments prior to receiving education. Coping was measured using the Ways of Coping Questionnaire. Questions on alcohol use were embedded in a self-administered portion of the assessment. A model testing the predictive value of coping behaviors in discriminating drinkers from nondrinkers was found to be significant (p < .0393). Caregivers who used self-controlling or distancing coping were more likely to be classified as drinkers, and those who used positive reappraisal or confrontive coping were more likely to be classified as nondrinkers. As the number of caregivers increases, gaininga greater understanding of relationships between caregiver copingand behaviors with potential for negative health and psychosocial consequences, such as alcohol use, can have useful applications in practice.
Microrelays With Bidirectional Electrothermal Electromagnetic Actuators and Liquid Metal Wetted Contacts

Microrelays with liquid metal wetted contacts have been demonstrated using bidirectional electrothermal electromagnetic actuators. These relays were fabricated with the Metal MUMPs foundry process, which has a 20-mum-thick nickel structural layer. The operating voltage is under 0.5 V. The measured breakdown voltage and off-state resistance are greater than 200 V and 100 MOmega, respectively, and the gold-to-gold contact resistance is around 0.3 Omega. When the contacts are wetted with liquid gallium alloy (melting point at -20degC), the measured contact resistance can be as low as 0.015 Omega. As such, these bidirectional relays could have potential applications in high-power switching systems with low contact resistance using liquid metal wetted contacts.
EEG Based Stress Monitoring

Everyone experiences stress in life. Moderate stress can be beneficial to human, however, excessive stress is harmful to the health. To monitor stress, different methods can be used. In this work, an algorithm for stress level recognition from Electroencephalogram (EEG) is proposed. To validate the algorithm, an experiment is designed and carried out with 9 subjects. A Stroop colour-word test is used as a stressor to induce 4 levels of stress, and the EEG data are recorded during the experiment. Different feature combinations and classifiers are proposed and analyzed. By combining fractal dimension and statistical features and using Support Vector Machine (SVM) as the classifier, four levels of stress can be recognized with an average accuracy of 67.06%, three levels of stress can be recognized with an accuracy of 75.22%, and two levels of stress can be recognized with an accuracy of 85.71%. The algorithm is integrated into the system CogniMeter for stress state monitoring. Stress level of the user is visualized on the meter in real time. The system can be applied for stress monitoring of air traffic controllers, operators, etc.
The Role of Group Member Affect in the Relationship between Trust and Cooperation

It is widely acknowledged that trust greatly affects work group functioning. Whereas trust may facilitate cooperation, distrust may impede it. Insight into when distrusters may be prompted to cooperate may therefore be of importance. Empirical studies point to several moderators of the effect of trust on cooperation. Unfortunately, these studies largely ignored the potential role of group member affect. Our study shows that group members' affective displays (particularly the activation level of the displays) have a substantial impact on the relationship between trust and cooperation. First, a scenario experiment (n=80) revealed that low trusting individuals were more willing to cooperate when confronted with group members who display high (versus low) activation affective states, whereas for more high trusting individuals cooperation was not contingent on other group members' affective displays. Second, a laboratory experiment (n=78), employing a social dilemma paradigm, replicated these findings and indicated that this effect is explained by the extent to which others are expected to cooperate. The discussion focuses on theoretical implications and managerial ramifications. Our study testifies to the significant role that affect may play in keeping up cooperation in organizations and work groups when trust is withering.
Laser‐induced liquid bead ion desorption‐MS of protein complexes from blue‐native gels, a sensitive top‐down proteomic approach

We have developed an experimental approach that combines two powerful methods for proteomic analysis of large membrane protein complexes: blue native electrophoresis (BNE or BN‐PAGE) and laser‐induced liquid bead ion desorption (LILBID) MS. Protein complexes were separated by BNE and eluted from the gel. The masses of the constituents of the multiprotein complexes were obtained by LILBID MS, a detergent‐tolerant method that is especially suitable for the characterisation of membrane proteins. High sensitivity and small sample volumes required for LILBID MS resulted in low demands on sample quantity. Eluate from a single band allowed assessing the mass of an entire multiprotein complex and its subunits. The method was validated with mitochondrial NADH:ubiquinone reductase from Yarrowia lipolytica. For this complex of 947 kDa, typically 30 μg or 32 pmol were sufficient to obtain spectra from which the subunit composition could be analysed. The resolution of this electrophoretic small‐scale approach to the purification of native complexes was improved markedly by further separation on a second dimension of BNE. Starting from a subcellular fraction obtained by differential centrifugation, this allowed the purification and analysis of the constituents of a large multiprotein complex in a single LILBID spectrum.
The Competitive Influences of Perceptual Load and Working Memory Guidance on Selective Attention

The perceptual load theory in selective attention literature proposes that the interference from task-irrelevant distractor is eliminated when perceptual capacity is fully consumed by task-relevant information. However, the biased competition model suggests that the contents of working memory (WM) can guide attentional selection automatically, even when this guidance is detrimental to visual search. An intriguing but unsolved question is what will happen when selective attention is influenced by both perceptual load and WM guidance. To study this issue, behavioral performances and event-related potentials (ERPs) were recorded when participants were presented with a cue to either identify or hold in memory and had to perform a visual search task subsequently, under conditions of low or high perceptual load. Behavioural data showed that high perceptual load eliminated the attentional capture by WM. The ERP results revealed an obvious WM guidance effect in P1 component with invalid trials eliciting larger P1 than neutral trials, regardless of the level of perceptual load. The interaction between perceptual load and WM guidance was significant for the posterior N1 component. The memory guidance effect on N1 was eliminated by high perceptual load. Standardized Low Resolution Electrical Tomography Analysis (sLORETA) showed that the WM guidance effect and the perceptual load effect on attention can be localized into the occipital area and parietal lobe, respectively. Merely identifying the cue produced no effect on the P1 or N1 component. These results suggest that in selective attention, the information held in WM could capture attention at the early stage of visual processing in the occipital cortex. Interestingly, this initial capture of attention by WM could be modulated by the level of perceptual load and the parietal lobe mediates target selection at the discrimination stage.
Objective ML: An Effective Object-Oriented Extension to ML

Objective ML is a small practical extension to ML with ob- jects and top level classes. It is fully compatible with ML; its type system is based on ML polymorphism, record types with polymorphic access, and a better treatment of type abbreviations. Objective ML allows for most fea- tures of object-oriented languages including multiple in- heritance, methods returning self and binary methods as well as parametric classes. This demonstrates that ob- jects can be added to strongly typed languages based on ML polymorphism. c ∞ 1997 John Wiley & Sons
VolumeExplorer: roaming large volumes to couple visualization and data processing for oil and gas exploration

In this paper, we present a volume roaming system dedicated to oil and gas exploration. Our system combines probe-based volume rendering with data processing and computing. The daily oil production and the estimation of the world proven-reserves directly affect the barrel price and have a strong impact on the economy. Among others, production and correct estimation are linked to the accuracy of the sub-surface model used for predicting oil reservoirs shape and size. Geoscientists build this model from the interpretation of seismic data, i.e. 3D images of the subsurface obtained from geophysical surveys. Our system couples visualization and data processing for the interpretation of seismic data. It is based on volume roaming along with efficient volume paging to manipulate the multi-gigabyte data sets commonly acquired during seismic surveys. Our volume rendering lenses implement high quality pre-integrated volume rendering with accurate lighting. They use a generic multi-modal volume rendering system that blends several volumes in the spirit of the "stencil" paradigm used in 2D painting programs. In addition, our system can interactively display non-polygonal isosurfaces painted with an attribute. Beside the visualization algorithms, automatic extraction of local features of the subsurface model also take full advantage of the volume paging.
