A case study on capturing and visualising face-to-face interactions in the workplace

Face-to-face interactions have proven to accelerate team and larger organisation success. Many past research has explored the benefits of quantifying face-to-face interactions for informed workplace management, with little attention being paid to how this information is perceived by the employees. In this paper, we offer a reflection on the automated feedback of personal interactions in a workplace through a longitudinal study of capturing, modelling and visualisation of face-to-face interactions of 47 employees for 4 months in an industrial research lab in Europe. We conducted semi-structured interviews with 20 employees to understand their perception and experience with the system. Our findings suggest that the short-term feedback on personal face-to-face interactions was not perceived as an effective external cue to promote self-reflection by most, and that employees desire long-term feedback annotated with actionable attributes.
Estimation of the multivariate distributions precision matrix learning

DIMA 2.0—predicted and known domain interactions

DIMA—the domain interaction map has evolved from a simple web server for domain phylogenetic profiling into an integrative prediction resource combining both experimental data on domain–domain interactions and predictions from two different algorithms. With this update, DIMA obtains greatly improved coverage at the level of genomes and domains as well as with respect to available prediction approaches. The domain phylogenetic profiling method now uses SIMAP as its backend for exhaustive domain hit coverage: 7038 Pfam domains were profiled over 460 completely sequenced genomes.Domain pair exclusion predictions were produced from 83 969 distinct protein–protein interactions obtained from IntAct resulting in 21 513 domain pairs with significant domain pair exclusion algorithm scores. Additional predictions applying the same algorithm to predicted protein interactions from STRING yielded 2378 high-confidence pairs. Experimental data comes from iPfam (3074) and 3did (3034 pairs), two databases identifying domain contacts in solved protein structures. Taken together, these two resources yielded 3653 distinct interacting domain pairs. DIMA is available at http://mips.gsf. de/genre/proj/dima.
The use of a metacognitive tool in an online social supportive learning environment: An activity theory analysis

This investigation is an exploratory study of the u s of a metacognitive software tool in a social supportive learning environment. The tool co mbined metacognitive knowledge and regulation functionality embedded within the conten t of an eight week online graduate education course. Twenty-three learners, who were practicing teachers, used the tool. Prior knowledge of metacognition, including responses to the Metacogni tive Awareness Inventory (Schraw & Dennison, 1994), was obtained. Prior knowledge of community instructional approaches was also obtained. Learner interviews focused on the m ediational aspects of the metacognitive tool and the social supportive learning environment, as well as an evaluation of the tool. Content analysis, combined with an activity theory framework, was used to analyze data. Findings are organized around three main themes: pr ior knowledge, the usability of the tool from design and technical perspectives, and the effectiv eness of the tool related to its design principles. The practicing teachers were found to be knowledgea ble bout metacognition and community; however, this knowledge did not often tr anslate into successful instruction. Learners found the metacognitive tool easy to use, but had difficulty with its design for conversation. They found activity theory disconnec tions between the tool and other course tools, and found the other tools more successful at creati ng community. The tool was evaluated as equally useful for metacognitive knowledge and regu lation, and more useful for more complex domain content than less complex content. Learners also found the tool useful for modeling the design of metacognitive instruction for their own t eaching. Conclusions are offered for improvements to metacog nitive instruction in general and in particular for the use of cognitive tools in a soci al supportive online learning environment.

ACTIVE LEARNING: THE IMPACT ON STUDENTS PARTICIPATING IN AN EXTENDED FIELD TRIP TO PUERTO RICO

Students in the Penn State course entitled Problem Solving in Tropical Agriculture (INTAG 481) participated in an extended field trip to Puerto Rico. They were interviewed prior to boarding the plane about their expectations and what they had learned at the inception of the semester. The students were randomly selected for interviews. The interviews suggest that students perceived the field trip to Puerto Rico to be a significant and valuable learning experience that could not have been duplicated in the classroom. This direct, hands-on involvement and meaningful exposure to a "real world" situation provided a learning experience students recognized as being both valuable and unattainable within the confines of the classroom. Their learning experience included not only learning the content material but also applying what they learned, developing sensitivity to another culture, and growing personally and professionally.
THE EFFECTS OF VARIABLE-MOMENTARY DIFFERENTIAL REINFORCEMENT ON TODDLER LOCATION PRIOR TO MEALS

Adoptability of classroom interventions should be considered when developing techniques for classroom management (Fantuzzo & Atkins, 1992). In the present study, we incorporated several components designed to enhance the practicality of a classroom intervention and evaluated their effect on toddler response allocation prior to meals. In the intervention condition, teachers transitioned each child to meals only when he was seated on a play mat (a requisite for engagement in teacher-led play activities). In the reversal condition, teachers selected each child to transition when he was by the barrier to the meal area (a practice commonly observed under natural conditions). When the data for all children were aggregated, the intervention increased the mean percentage of intervals children were on the play mat and decreased the percentage of intervals children were by the barrier. An examination of individual child data showed positive outcomes for 5 of the 6 children.
Variable resolution 4-k meshes

We introduce variable resolution 4-k meshes, a powerful structure for the representation of geometric objects at multiple levels of detail. It combines most properties of other related descriptions with several advantages, such as more flexibility and greater expressive power. The main unique feature of the 4-k mesh structure lies in its variable resolution capability, which is crucial for adaptive computation. We also give an overview of the different methods for constructing the hierarchical 4-k mesh representation, as well as the basic algorithms necessary to incorporate it in modeling and graphics applications.

Development of ethanol withdrawal-related sensitization and relapse drinking in mice selected for high- or low-ethanol preference.

BACKGROUND Previous studies have shown that high alcohol consumption is associated with low withdrawal susceptibility, while at the same time, other studies have shown that exposure to ethanol vapor increases alcohol drinking in rats and mice. In the present studies, we sought to shed light on this seeming contradiction using mice selectively bred for High- (HAP) and Low- (LAP) Alcohol Preference, first, assessing these lines for differences in signs of ethanol withdrawal and second, for differences in the efficacy of intermittent alcohol vapor exposure on elevating subsequent ethanol intake. METHODS Experiment 1 examined whether these lines of mice differed in ethanol withdrawal-induced CNS hyperexcitability and the development of sensitization to this effect following intermittent ethanol vapor exposure. Adult HAP and LAP lines (replicates 1 and 2), and the C3H/HeNcr inbred strain (included as a control genotype for comparison purposes) received intermittent exposure to ethanol vapor and were evaluated for ethanol withdrawal-induced seizures assessed by scoring handling-induced convulsions (HIC). Experiment 2 examined the influence of chronic intermittent ethanol exposure on voluntary ethanol drinking. Adult male and female HAP-2 and LAP-2 mice, along with male C57BL/6J (included as comparative controls) were trained to drink 10% ethanol using a limited access (2 h/d) 2-bottle choice paradigm. After stable baseline daily intake was established, mice received chronic intermittent ethanol vapor exposure in inhalation chambers. Ethanol intake sessions resumed 72 hours after final ethanol (or air) exposure for 5 consecutive days. RESULTS Following chronic ethanol treatment, LAP mice exhibited overall greater withdrawal seizure activity compared with HAP mice. In Experiment 2, chronic ethanol exposure/withdrawal resulted in a significant increase in ethanol intake in male C57BL/6J, and modestly elevated intake in HAP-2 male mice. Ethanol intake for male control mice did not change from baseline levels of intake. In contrast, HAP-2 female and LAP-2 mice of both sexes did not show changes in ethanol intake as a consequence of intermittent ethanol exposure. CONCLUSIONS Overall, these results indicate that the magnitude of ethanol withdrawal-related seizures is inversely related to inherited ethanol intake preference. Additionally, intermittent ethanol vapor exposure appears more likely to affect high-drinking mice (C57BL/6J and HAP-2) than low drinkers, although these animals are less affected by ethanol withdrawal.
Performing aggressive maneuvers using iterative learning control

This paper presents an algorithm to iteratively drive a system quickly from one state to another. A simple model which captures the essential features of the system is used to compute the reference trajectory as the solution of an optimal control problem. Based on a lifted domain description of that same model an iterative learning controller is synthesized by solving a linear least-squares problem. The non-causality of the approach makes it possible to anticipate recurring disturbances. Computational requirements are modest, allowing controller update in real-time. The experience gained from successful maneuvers can be used to significantly reduce transients when performing similar motions. The algorithm is successfully applied to a real quadrotor unmanned aerial vehicle. The results are presented and discussed.
Development of autonomous flight control system for 50m unmanned airship

The unmanned airship has a capability of autonomous flight, navigation and guidance based on a telemetry command of the ground control station. In particular the unmanned airship has the peculiar characteristics of a long-duration station keeping within the given boundary compared to the UAV or fixed wing aircraft. Under these circumstances the autonomous flight control system (AFCS) is a critical system and plays a key role in achieving the given requirements and missions. The main functions of AFCS consist of three categories. First, it controls all flight operation modes and unmanned airship dynamics by the autopilot system and control laws. Second, it delivers telecommand and telemetric information between the ground control station and the onboard communication system. Finally it manages and operates a subsystem such as the electric system, propulsive system and pressurization system. In this paper, we introduce the overall design architecture of the main hardware and software of the flight control systems including flight management system (FMS) in a 50 m-long unmanned airship developed by KARI.
Estimation of dynamic linear models in short panels with ordinal observation

We develop a simulated ML method for short-panel estimation of one or more dynamic linear equations, where the dependent variables are only partially observed through ordinal scales. We argue that this latent autoregression (LAR) model is often more appropriate than the usual state-dependence (SD) probit model for attitudinal and interval variables. We propose a score test for assisting in the treatment of initial conditions and a new simulation approach to calculate the required partial derivative matrices. An illustrative application to a model of households' perceptions of their financial well-being demonstrates the superior fit of the LAR model.
Jano: specification and enforcement of location privacy in mobile and pervasive environments

Today there are many location technologies providing people or object location. However, location privacy must be ensured before providing widely disseminated location services. Privacy rules may depend not only on the identity of the requester, but also on past events such as the places visited by the person being located, or previous location queries. So, location systems must support the specification and enforcement of security policies allowing users to specify when, how and who can know their location. We propose a middleware platform named Jano1 supporting both pull and push location requests while enforcing configurable security policies. Policies are specified using the Security Policy Language - SPL, facilitating the use of well known security models. In particular, Jano supports history-based policies applied to persons or objects location. The system was implemented with the integration of several location technologies (e.g. GPS, Bluetooth, etc.), and dealing with the heterogeneity aspects. It provides an interface that facilitates policy specification and has good performance.
NBS1 mediates ATR-dependent RPA hyperphosphorylation following replication-fork stall and collapse

Post-translational phosphorylation of proteins provides a mechanism for cells to switch on or off many diverse processes, including responses to replication stress. Replication-stress-induced phosphorylation enables the rapid activation of numerous proteins involved in DNA replication, DNA repair and cell cycle checkpoints, including replication protein A (RPA). Here, we report that hydroxyurea (HU)-induced RPA phosphorylation requires both NBS1 (NBN) and NBS1 phosphorylation. Transfection of both phosphospecific and nonphosphospecific anti-NBS1 antibodies blocked hyperphosphorylation of RPA in HeLa cells. Nijmegen breakage syndrome (NBS) cells stably transfected with an empty vector or with S343A-NBS1 or S278A/S343A phospho-mutants were unable to hyperphosphorylate RPA in DNA-damage-associated foci following HU treatment. The stable transfection of fully functional NBS1 in NBS cells restored RPA hyperphosphorylation. Retention of ATR on chromatin in both NBS cells and in NBS cells expressing S278A/S343A NBS1 mutants decreased after DNA damage, suggesting that ATR is the kinase responsible for RPA phosphorylation. The importance of RPA hyperphosphorylation is demonstrated by the ability of cells expressing a phospho-mutant form of RPA32 (RPA2) to suppress and delay HU-induced apoptosis. Our findings suggest that RPA hyperphosphorylation requires NBS1 and is important for the cellular response to DNA damage.
The Relative Influence of Accommodation and Convergence in the Judgment of Distance

Resume Le but de cette etude a ete d'evaluer, en termes quantitatifs, l'influence relative de l'accommodation et de la convergence dans le jugement de la distance. On a employe une nouvelle forme de stereoscope a miroir au moyen duquel il a ete possible de varier la convergence pendant que l'accommodation, la grandeur de l'image retinale, l'intensite de l'objet stereoscopique et tous les autres criteres secondaires de la distance visuelle sont restes constants.

Serum adiponectin helps to differentiate type 1 and type 2 diabetes among young Asian Indians.

OBJECTIVE This study assessed whether serum adiponectin could be used as a biochemical marker to differentiate type 1 diabetes mellitus (T1DM) from type 2 diabetes mellitus (T2DM) among young Asian Indians. RESEARCH DESIGN AND METHODS We recruited age- and sex-matched individuals with physician-diagnosed T1DM (n=70) and T2DM (n=72). All were 12-27 years of age with a duration of diabetes of >2 years, at a large tertiary-care diabetes center in Chennai, southern India. Age- and sex-matched individuals with normal glucose tolerance (NGT) (n=68) were selected from an ongoing population study. NGT was defined using World Health Organization criteria. Serum total adiponectin was measured by enzyme-linked immunosorbent assay. Receiver operating characteristic (ROC) curves were used to identify adiponectin cut points for discriminating T1DM from T2DM. RESULTS Adiponectin levels were higher in T1DM and lower in T2DM compared with the NGT group (9.89, 3.88, and 6.84 μg/mL, respectively; P<0.001). In standardized polytomous regression models, adiponectin was associated with T1DM (odds ratio [OR]=1.131 per SD; 95% confidence interval [CI], 1.025-1.249) and T2DM (OR=0.628 per SD; 95% CI, 0.504-0.721) controlled for age, gender, waist circumference, body mass index, hypertension, glycated hemoglobin, total cholesterol, serum triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, family history of T2DM, and estimated glomerular filtration rate. Using ROC analysis, an adiponectin cut point of 5.1 μg/mL had a C statistic of 0.886 (95% CI, 0.836-0.953), sensitivity of 80.6%, and specificity of 80.6% to differentiate T1DM from T2DM. Using the 5.1 μg/mL cut point, 80.6% of T1DM and 81.8% of T2DM would be correctly classified. CONCLUSIONS Serum adiponectin is a useful biochemical marker for differentiating T1DM and T2DM among young Asian Indians.
Action and reflection : dual-medium primary schooling as language policy realisation : Many languages in education : issues of implementation

The article begins by explaining the need for dual-medium schooling in South Africa today, particularly for the African-language-speaking majority. It arises out of the impossibility, on attitudinal grounds, of implementing a home-language or mother-tongue educational policy throughout schooling, on the one hand, and the simultaneous failure of the current English-Second-Language system, on the other. Following a foundational phase of home-language education, a dual-medium curriculum combines the pedagogical advantages of home-language teaching and learning with maximal opportunities to gain proficiency in English. Dual-medium education is in synchrony with the national language-in-education policy (LiEP, 1997), and has recently been endorsed by the Minister of Education as a way of realising the LiEP. The article then describes a case study of an ongoing dual-medium (Xhosa/English) educational programme in two township primary schools in Cape Town. It traces the trajectory of the programme from initial classroom observations through the formulation of a new school language policy to curricular intervention and research. Particular attention is paid to emergent literacy approaches, and to the methodological and terminological problems and possibilities of dual-medium science education. The programme's action research orientation is explained. The paper concludes with a series of recommendations to provincial education authorities on additional strategies for realising the LiEP.
[POSTER] Background Image Registration as a Post-Processing Technique in Diminished Reality Rendering Procedures

Diminished reality (DR) is a technique to remove undesirable objects from a video stream in real time. DR methods calculate a user's camera pose using vision- or sensor-based approaches to recover and overlay a background image to the camera view. Relying on 6DoF camera registration methods, DR results are often ruined due to misregistration. To solve this problem, we propose a registration framework as a post-processing technique in diminished reality rendering procedures to reduce the misalignment in an image space. We also reproduce motion blur to improve the image space alignment in the post-processing. The results showed remarkable improvement compared to sensor-based DR results. We argue that this postprocessing-based approach can be applied to almost all existing DR methods to improve their quality.
Applying Research in Motivation and Learning to Music Education

Current research on motivation and learning may assist teachers in identifying strategies to help students be successful and persevere in the music classroom. Students’ beliefs about their ability to learn, and the impact these beliefs have on their motivation to learn music, is a large focus of the research presented here. Aspects of music make it unique from other academic disciplines on student motivation. There are different motivational patterns exhibited at different age levels. Being aware of these various aspects may help teachers foster positive beliefs among students about their own music potential. This article presents a review of motivation and learning research literature and provides implications for today’s music classrooms and teaching profession. Suggestions are provided to change perception of talent, widen the scope of musical activities in schools, include authentic assessments, and have teachers learn how to increase student motivation and learning in the music classroom.
What Happened on Deliberation Day?

What are the effects of deliberation about political issues? This essay reports the results of a kind of Deliberation Day, involving sixty-three citizens in Colorado. Groups from Boulder, a predominantly liberal city, met and discussed global warming, affirmative action, and civil unions for same-sex couples; groups from Colorado Springs, a predominately conservative city, met to discuss the same issues. The major effect of deliberation was to make group members more extreme than they were when they started to talk. Liberals became more liberal on all three issues; conservatives became more conservative. As a result, the division between the citizens of Boulder and the citizens of Colorado Springs were significantly increased as a result of intragroup deliberation. Deliberation also increased consensus, and dampened diversity, within the groups. Implications are explored for the uses and structure of deliberation in general.
