Does context matter? Study of knowledge sharing in European Institute of Innovation and Technology

Some previous attempts to draw research on social constructs as if they are operating in a vacuum were missing some valuable information and could not provide deep insights into the matter. As this, contextual sensitivity, approach is not yet popular in network research, we adopt this stance to provide valuable insights into knowledge sharing in complex interorganizational networks. The empirical study was based on interviews, observations and focus groups implemented in two interorganizational networks: knowledge and innovation communities (KICs). The perceptions of network’s context and content of their members provide deeper insights into all the other issues of networking, knowledge sharing included. In our research these perceptions were related to member’s discourses to knowledge sharing. Even though this finding should not be adopted as a framework for future research, the contextual sensitivity approach should not be neglected in network research.
HPV Vaccination to Prevent HIV Infection: Time for Randomized Controlled Trials

Despite many years of rigorous evaluation of a variety of interventions, HIV incidence rates in parts of Africa remain unacceptably high. A recent review identified 37 randomized controlled trials testing interventions to reduce HIV incidence.1 Except for 3 randomized controlled trials of male circumcision2‐4 and 1 trial of syndromic treatment of sexually transmitted diseases,5 and, recently, 1 trial of a vaginal microbicide,6 no significant reductions in HIV incidence were observed. In some trials of vaginal microbicides, trial participants in the active treatment arm actually had increased HIV incidence rates.7 Trials with candidate vaccines have been equally disappointing.8 A recently completed trial of a prime-boost strategy conducted in Thailand showed statistically significant, but limited, protection against HIV.9 Nevertheless, even vaccine optimists think that a preventive HIV vaccine is many years away. Sexually transmitted infections (STIs) were identified as important cofactors for HIV transmission early in the epidemic.10,11 Many prospective observational studies showed that the presence of ulcerative and nonulcerative STIs increased the likelihood of HIV transmission.10,11 Several interventions were based on this observation including mass treatment with antibiotics,12 improved syndromic management of STIs,5,13 and herpes simplex virus (HSV)-2 suppressive treatment.14 Null findings of these interventions should be interpreted with caution. Failure to show an effect does not necessarily mean that the STI is not causally associated with HIV. As Barnabas and Wasserheit highlight,15 the stage of the HIV epidemic in which an intervention trial is conducted may significantly influence observed efficacy. Another possible reason for the failure of these trials to demonstrate efficacy is that the intervention may not have adequately controlled the STI or its biologic effects.
A new local feature descriptor: Covariant support region

Detection and description of Local feature covariant region is a new technology of image contents and image semantic representations, it has become an important foundation of the image recognition, learning and understanding. First, a Laplace of Gaussian corner detection method is proposed based on edge contour, in the meantime, a new local feature descriptor, named covariant support region, is introduced. Then, a detection algorithm of covariant support region is framed, whose covariant properties of rotation and scale are also proved. Comparing with previous studies, the computational complexity is significantly reduced by this method. The data of simulative experiments indicate that the method has good performance on higher accuracy, higher repeatability, and lower complexity.
Improved tangent estimate in the nudged elastic band method for finding minimum energy paths and saddle points

An improved way of estimating the local tangent in the nudged elastic band method for finding minimum energy paths is presented. In systems where the force along the minimum energy path is large compared to the restoring force perpendicular to the path and when many images of the system are included in the elastic band, kinks can develop and prevent the band from converging to the minimum energy path. We show how the kinks arise and present an improved way of estimating the local tangent which solves the problem. The task of finding an accurate energy and configuration for the saddle point is also discussed and examples given where a complementary method, the dimer method, is used to efficiently converge to the saddle point. Both methods only require the first derivative of the energy and can, therefore, easily be applied in plane wave based density-functional theory calculations. Examples are given from studies of the exchange diffusion mechanism in a Si crystal, Al addimer formation on the Al(100) surfa.
Endogenous Neuromagnetic Activity for Mental Hierarchy of Timing

The frontal-striatal circuits, the cerebellum, and motor cortices play crucial roles in processing timing information on second to millisecond scales. However, little is known about the physiological mechanism underlying human's preference to robustly encode a sequence of time intervals into a mental hierarchy of temporal units called meter. This is especially salient in music: temporal patterns are typically interpreted as integer multiples of a basic unit (i.e., the beat) and accommodated into a global context such as march or waltz. With magnetoencephalography and spatial-filtering source analysis, we demonstrated that the time courses of neural activities index a subjectively induced meter context. Auditory evoked responses from hippocampus, basal ganglia, and auditory and association cortices showed a significant contrast between march and waltz metric conditions during listening to identical click stimuli. Specifically, the right hippocampus was activated differentially at 80 ms to the march downbeat (the count one) and ∼250 ms to the waltz downbeat. In contrast, basal ganglia showed a larger 80 ms peak for march downbeat than waltz. The metric contrast was also expressed in long-latency responses in the right temporal lobe. These findings suggest that anticipatory processes in the hippocampal memory system and temporal computation mechanism in the basal ganglia circuits facilitate endogenous activities in auditory and association cortices through feedback loops. The close interaction of auditory, motor, and limbic systems suggests a distributed network for metric organization in temporal processing and its relevance for musical behavior.
Capabilities of R Package mixAK for Clustering Based on Multivariate Continuous and Discrete Longitudinal Data

R package mixAK originally implemented routines primarily for Bayesian estimation of finite normal mixture models for possibly interval-censored data. The functionality of the package was considerably enhanced by implementing methods for Bayesian estimation of mixtures of multivariate generalized linear mixed models proposed in Komarek and Komarkova (2013). Among other things, this allows for a cluster analysis (classification) based on multivariate continuous and discrete longitudinal data that arise whenever multiple outcomes of a different nature are recorded in a longitudinal study. This package also allows for a data-driven selection of a number of clusters as methods for selecting a number of mixture components were implemented. A model and clustering methodology for multivariate continuous and discrete longitudinal data is overviewed. Further, a step-by-step cluster analysis based jointly on three longitudinal variables of different types (continuous, count, dichotomous) is given, which provides a user manual for using the package for similar problems.
Teacher Language Awareness as an Important Element in Teacher Professionalism and Autonomy

Being an autonomous person means being responsible for one’s actions and accepting the consequences of one’s behavior. Autonomy introduced to teaching comprises a cluster of behavior capacities characteristic of human interdependence. In the field of teaching, the development of autonomy is pursued as a matter of conscious intention, and its presence can be recognized in teacher’s behaviors which are shaped by reflection. This paper focuses on teacher language awareness (TLA) and the relationship between TLA and other dimensions of teacher knowledge. It aims at presenting TLA as one of the key elements of teacher professional development and autonomy. The author focuses on the definition of TLA and discusses a number of factors contributing towards the complexity of TLA. Subsequently the role of TLA in structuring input for learners is analyzed as well as the relationship between TLA and pedagogical practice, and factors affecting the application of TLA in the classroom. Moreover, connections between teachers’ cognitions and practices in teaching grammar will be presented. Finally, TLA and teacher professionalism will be summarized.

Further Observations of the Tilted Planet XO-3: A New Determination of Spin-Orbit Misalignment, and Limits on Differential Rotation

We report on observations of the Rossiter–McLaughlin (RM) effect for the XO-3 exoplanetary system. The RM effect for the system was previously measured by two different groups, but their results were statistically inconsistent. To obtain a decisive result, we observed two full transits of XO-3b with the Subaru 8.2-m telescope. By modeling these data with a new and more accurate analytic formula for the RM effect, we found the projected spin–orbit angle
Knowledge Sharing Platform - Knowledge Processing Line and its Components

Group knowledge sharing has been an ad hoc issue in knowledge management. Towards an efficient knowledge sharing platform, the Knowledge Processing Line (KPL) is developed which focuses on the problem solving and its modules. Such platform contains two main parts, one is Open Research Experiment Platform (OREP), which is a universal platform with all kinds of knowledge processing modules for knowledge workers to coordinate their knowledge, such as various types of data, algorithms and functional modules; the other is Knowledge Processing Line Manager (KPLM) which supports the integration of knowledge involved in the problem solving process for reference and reuse. Some applications have proved the effectiveness of the developed knowledge sharing platform.
Ensembles of k-nearest neighbors and dimensionality reduction

In this paper, ensembles of k-nearest neighbors classifiers are explored for gene expression cancer classification, where each classifier is linked to a randomly selected subset of genes. It is experimentally demonstrated using five datasets that such ensembles can yield both good accuracy and dimensionality reduction. If a characteristic called dataset complexity guides which random subset to include into an ensemble, then the ensemble achieves even better performance.
Does neuroanatomy account for superior temporal dysfunction in early psychosis? A multimodal MRI investigation.

BACKGROUND Neuroimaging studies of ultra-high risk (UHR) and first-episode psychosis (FEP) have revealed widespread alterations in brain structure and function. Recent evidence suggests there is an intrinsic relationship between these 2 types of alterations; however, there is very little research linking these 2 modalities in the early stages of psychosis. METHODS To test the hypothesis that functional alteration in UHR and FEP articipants would be associated with corresponding structural alteration, we examined brain function and structure in these participants as well as in a group of healthy controls using multimodal MRI. The data were analyzed using statistical parametric mapping. RESULTS We included 24 participants in the FEP group, 18 in the UHR group and 21 in the control group. Patients in the FEP group showed a reduction in functional activation in the left superior temporal gyrus relative to controls, and the UHR group showed intermediate values. The same region showed a corresponding reduction in grey matter volume in the FEP group relative to controls. However, while the difference in grey matter volume remained significant after including functional activation as a covariate of no interest, the reduction in functional activation was no longer evident after including grey matter volume as a covariate of no interest. LIMITATIONS Our sample size was relatively small. All participants in the FEP group and 2 in the UHR group had received antipsychotic medication, which may have impacted neurofunction and/or neuroanatomy. CONCLUSION Our results suggest that superior temporal dysfunction in early psychosis is accounted for by a corresponding alteration in grey matter volume. This finding has important implications for the interpretation of functional alteration in early psychosis.
Multidimensional Techniques for Privacy Preservation in Datasets

Applications in commercial domains possess large datasets on individuals. This data includes private and sensitive information e.g. patient diseases, bank account details, organization structural details etc. When data mining techniques are applied on these applications the private and sensitive information of the subjects will be revealed. However, it is necessary to share the information in such a way that the identities of the individuals are not revealed. So it is necessary to anonymize the data. For this the quasi attribute set (attribute set that can be linked with original dataset to re-identify individuals) has to identified and anonymized. This paper presents the summary of various anonymization techniques Multidimensional generalization, Multidimensional suppression, Multidimensional Clustering and Multidimensional Cryptography to provide privacy for individuals. Any of these techniques can be applied to achieve privacy for individuals in a better manner. I. Introduction Knowledge discovery is the process of extracting valid, useful and understandable patterns from large databases or information repositories. Data mining plays a key role in knowledge discovery process. Many organizations publish micro data that includes public health and demographic information for different purposes. The private and sensitive details of users will be released when the data mining techniques are applied on these databases. The users require that this details to be confidential [1-3]. Although attributes that clearly identify individuals, such as Name, social security number are removed while releasing the data, these databases can sometimes be linked with other public databases like voter registration table etc on attributes such as Zip code, date of birth to re-identify individuals whose databases were supposed to remain anonymous. [4] This is shown in fig. 1 and fig. 2. Fig. 1, shows an employee Table with attributes employee number (empno), name, last name, date of birth (DOB) and salary for different employees.
Prevalence of Metabolic Abnormalities in Children with Varying Degrees of Obesity

As the prevalence of obesity among children has risen, metabolic syndrome, a cluster of abnormalities which includes obesity, altered glucose metabolism, hypertension, and dyslipidemia, has increasingly become recognized in the pediatric population. Metabolic syndrome has been studied extensively in adults, and there is increasing interest to understand the condition in adolescents; however, studies of metabolic syndrome in younger children are limited. The purpose of this study is to examine the prevalence of metabolic syndrome and its individual components among children aged 6-10 years. Demographic, anthropometric, and biochemical data were gathered retrospectively from the medical records of 222 obese children aged 6-10 years who were seen as new patients in a hospital-based clinic for management of obesity and related conditions. The results of this study suggest that the study population is at high risk of morbidity; 77.9% of subjects had at least one metabolic abnormality in addition to obesity, and 27.9% of subjects in this study had metabolic syndrome. This study found a high risk of elevated systolic blood pressure and elevated fasting insulin in the study population, with 63.1% of subjects having prehypertension or hypertension and 40.1% of subjects having elevated fasting insulin. The results of this study suggest that current recommendations for screening of metabolic abnormalities in obese school-age children are not sufficiently aggressive. Current standards of practice do not include assessment for metabolic syndrome components in children under the age of 10 years, with the exception of blood pressure. The prevalence of impaired glucose metabolism, insulin resistance, and dyslipidemia, however, is significant in this population, and screening for these abnormalities in children under the age of 10 is warranted.
Engaging new digital locals with interactive urban screens to collaboratively improve the city

Local governments struggle to engage time poor and seemingly apathetic citizens, as well as the city's young digital natives, the digital locals. This project aims at providing a lightweight, technological contribution towards removing the hierarchy between those who build the city and those who use it. We aim to narrow this gap by enhancing people's experience of physical spaces with digital, civic technologies that are directly accessible within that space. This paper presents the findings of a design trial allowing users to interact with a public screen via their mobile phones. The screen facilitated a feedback platform about a concrete urban planning project by promoting specific questions and encouraging direct, in-situ, real-time responses via SMS and twitter. This new mechanism offers additional benefits for civic participation as it gives voice to residents who otherwise would not be heard. It also promotes a positive attitude towards local governments and gathers information different from more traditional public engagement tools.
Non-Identity Check Remains QMA-Complete for Short Circuits

The Non-Identity Check problem asks whether a given a quantum circuit is far away from the identity or not. It is well known that this problem is QMA-Complete \cite{JWB05}. In this note, it is shown that the Non-Identity Check problem remains QMA-Complete for circuits of short depth. Specifically, we prove that for constant depth quantum circuit in which each gate is given to at least $\Omega(\log n)$ bits of precision, the Non-Identity Check problem is QMA-Complete. It also follows that the hardness of the problem remains for polylogarithmic depth circuit consisting of only gates from any universal gate set and for logarithmic depth circuit using some specific universal gate set.
Improved Password Selection Method to Prevent Data Thefts

Password thefts have become an important data security issue in the recent times. Hackers have been intruding into the websites and personal mail accounts of the users. Prevention from this unauthorized access is the need of the hour. So here lies the major key to overcome such a situation and that is to adopt more secure and advanced password selection methods. My paper throws light on one of the most secure methods to improve password strength and security.
Codesigning emancipatory systems: a study on mobile applications and lesbian, gay, bisexual, and transgender (LGBT) issues

HCI is a well-suited discipline for designing systems intended to support disenfranchised groups. The LGBT population is increasingly gaining visibility, but the range of subjects they are affected by prejudice and exclusion is wide. This work begins by a review on LGBT issues in HCI literature and mobile applications. We point out a lack of consideration of LGBT people as designers and critical approaches, explicitly aiming to not only understand but effectively act on social issues. In addition, few mobile applications disclose a critical goal, despite their potential impact on health, alterity, empathy, safety, and sociability. Then, we describe a semioparticipatory approach for codesign, focusing on the first conducted activities where the relations between mobile applications and LGBT issues were discussed with volunteers interested in the subject. Finally, we present the concept of a novel application aiming at the support and protection of LGBT people.
Acute subdural hematoma with severe traumatic brain edema evacuated by Dural-stabs -A new brain preserving technique

The Department of Neurosurgery Sher-i-Kashmir Institute of Medical Sciences (SKIMS) Srinagar, a single neurosurgical centre in Kashmir valley, assessed prospectively, under a uniform protocol, 120 patients of severe traumatic brain edema with acute subdural hema-toma by wide decompressive craniectomy with dural-stabs in 60(cases) patients as against conventional dural opening (open dural flap) and removal of acute subdural hematoma in 60(controls) patients during a period of 3 years from Jun. 2006 to Jun. 2009. A free bone flap was elevated and preserved. All patients had GCS (Glassgow Coma Scale) score of 8 and less. The elective ventilation and ICP monitoring was carried out in all patients. Most patients were young and males with a mean age of 30 years in both groups. The overall survival of the dural-stab group (case-study) was 78.3% with good recovery in 43.3% and a mortality of 21.6% (13/60) as compared to 40% survival in open dural flap (control) group with 11.6% good recovery and a mortality of 60% (36/60) . The conventional (open dural flap) procedure to remove the clot proved dangerous in a traumatic “vent-searching” and edematous brain, restricted in a rigid cranial vault. This midway-approach, known in SKIMS as “Dural-Stabs”, between the only decompressive craniectomy and removal of acute subdural clot by open dural flap (conventional) method, proved much effective in increasing survival of pa-tients with low GCS and severe traumatic brain edema with acute subdural hematoma. In conclusion decompressive craniectomy alone is not sufficient and open dural flap is full of risk in such patients. The new innovative and indigenous technique is much favourable to the patient outcome.
