Sustaining the Future of the Public Sector: Insights into a Swedish Municipality's Dealing with Knowledge Management and Succession Planning
Venue: J. Inf. Knowl. Manag.

The ageing workforce soon leads to a number of retirements in government organisations that will put the knowledge basis at risk. Addressing this point the present study provides an analysis and evaluation of a Swedish municipality's dealing with the aspects of knowledge management and succession planning against the background of demographic developments and the increased relevance of knowledge. It reports findings based on semi structured interviews conducted with executive staff of the municipality. Results of data analysed show that the municipality is far from being ready to master the challenges ahead. To date the municipality follows a sporadic approach rather than a strategic and planned one when addressing the issue of succession planning. Indeed, the findings suggest that a muddling through approach prevails. Based on the findings some suggestions were derived that may help both municipalities facing similar circumstances as well as policy makers drafting suitable policies.
Lending a Helping Hand at Work: A Multilevel Investigation of Prosocial Motivation, Inclusive Climate and Inclusive Behavior
Venue: Journal of Occupational Rehabilitation

People with disabilities often encounter difficulties at the workplace such as exclusion or unfair treatment. Researchers have therefore pointed to the need to focus on behavior that fosters inclusion as well as variables that are antecedents of such 'inclusive behavior' Therefore the purpose of this study was to research the relationship between prosocial motivation, team inclusive climate and employee inclusive behavior.  A survey was conducted among a sample of 282 paired employees and colleagues, which were nested in 84 teams. Employees self rated prosocial motivation and team inclusive climate, their inclusive behavior was assessed by colleagues. Hypotheses were tested using multilevel random coefficient modeling.  Employees who are prosocially motivated will display more inclusive behavior towards people with disabilities, and this relationship is moderated by team inclusive climate in such a way that the relationship is stronger when the inclusive climate is high.  This study shows that inclusive organizations, which value a diverse workforce, need to be aware of not only individual employee characteristics, but also team level climate to ensure the smooth integrations of people with disabilities into regular work teams.
IoT enabled environmental monitoring system for smart cities
Venue: 2016 International Conference on Internet of Things and Applications (IOTA)

A smart city enables the effective utilization of resources and better quality of services to the citizens. To provide services such as air quality management, weather monitoring and automation of homes and buildings in a smart city, the basic parameters are temperature, humidity and CO2. This paper presents a customised design of an Internet of Things (IoT) enabled environment monitoring system to monitor temperature, humidity and CO2. In developed system, data is sent from the transmitter node to the receiver node. The data received at the receiver node is monitored and recorded in an excel sheet in a personal computer (PC) through a Graphical User Interface (GUI) made in LabVIEW. An Android application has also been developed through which data is transferred from LabVIEW to a smartphone, for monitoring data remotely. The results and the performance of the proposed system is discussed.
60 GHz Statistical Channel Characterization for Wireless Data Centers
Venue: IEEE Antennas and Wireless Propagation Letters

This letter presents 60 GHz radio channel measurements and characterization in a productivity data center. Path loss and delay spread are statistically modeled for possible use cases corresponding to potential deployment scenarios in a wireless data center (WDC) Models behaviors are then used to highlight the propagation differences across use cases. It was found that most use cases are characterized by a rich scattering channel and sub free space path loss exponent values. Compared to common indoor environments, delay spread and path loss values suggest a better link budget at higher distances and possibly higher interference in dense deployment scenarios. The reported models and key propagation behaviors are useful for practical system design and evaluation of WDC millimeter wave links.
Theory of solid effect and cross effect dynamic nuclear polarization with half integer high spin metal polarizing agents in rotating solids.
Venue: Physical chemistry chemical physics PCCP

Dynamic nuclear polarization (DNP) is a powerful method to enhance sensitivity especially of solid state magic angle spinning (MAS) NMR by up to several orders of magnitude. The increased interest both from a practical as well as theoretical viewpoint has spawned several fields of active research such as the development of new polarizing agents with improved or unique properties and description of the underlying DNP mechanisms such as solid effect (SE) and cross effect (CE) Even though a novel class of unique polarizing agents based on high spin metal ions such as Gd(iii) and Mn(ii) has already been utilized for MAS DNP a theoretical description of the involved DNP mechanism is still incomplete. Here, we review several aspects of DNP relevant electron paramagnetic resonance (EPR) properties of the general class of these half integer high spin metal ions with isotropic Zeeman interaction but significant zero field splitting (ZFS) While the SE can be relatively easily described similar to that of a S 1/2 system and is assumed to be effective only for polarizing agents featuring a narrow central EPR transitions (i.e. mS 1/2 +1/2) with respect to the nuclear Larmor frequency, the CE between two high spin ions requires a more detailed theoretical investigation due to a multitude of possible transitions and matching conditions. This is especially interesting in light of recent understanding of CE being induced by MAS driven level anti crossings (LACs) between dipolar coupled electron spins. We discuss the requirements of such CE enabling LACs to occur due to anisotropy of ZFS, the expected adiabaticity, and the resulting possibilities of high spin metal ion pairs to act as polarizing agents for DNP. This theoretical description serves as a framework for a detailed experimental study published directly following this work.
Combined traveling wave and fuzzy logic based fault location in multi terminal HVDC systems
Venue: 2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC)

The voltage source converter (VSC) multi terminal high voltage direct current (MTHVDC) is a suitable solution to connect offshore large renewable power stations. However, relevant fast and intelligent fault current location techniques are of utmost importance to improve power system stability and maintain continuity of supply. This paper proposes a hybrid travelling wave fuzzy logic based wavelet decomposition technique to identify the faulty line in a MTHVDC network, in addition to accurately determine the fault location. A fuzzy logic voter is applied to analyze non stationary current travelling waves generated at fault location and captured by special DC current sensors to identify the faulted pole. Secondly, the captured wave of the identified pole is further decomposed by a discrete wavelet analyzer to accurately identify the fault location. A MATLAB toolbox is constructed to show the validity and adequacy of the proposed algorithm. This technique is important to MTHVDC dispatch centers especially those used with offshore wind farms.
Impact of Job Satisfaction on Retention of Employees in BPO Industry

Human Capital is the utmost vital resource on which the Information Technology Information Technology Enabled Services (IT ITES) depends. One of the greatest challenges for today's administrators lies in building a workplace that employees want to persist with and outsiders want to be hired into. Therefore, an employer's foremost responsibility is retention of its best employees and this can be attained only by keeping the employees satisfied and motivated. Focusing on employee satisfaction can positively impact the organization as it increases employee productivity, performance, quality of work, profits, commitment to the organization and reduces turnover and absenteeism. The present paper is an attempt to study the impact of job satisfaction on the employee retention, which is measured by a structured questionnaire administered to the middle level employees in leading BPO companies in Jaipur.

Therefore, studies related to job satisfaction have increased over the past few years as many organisations realised its value. The growing interest in job satisfaction is justified by the fact that in today's business conditions, employees and their knowledge are becoming key factors in achieving competitive advantage. Employee retention and all of the elements associated with job satisfaction has become the primary focus of many organisations. The aim of this research was to establish whether job satisfaction has an impact on employee retention at Lonmin Rowland Shaft in the North West Province. This research identified key variables that contribute to job satisfaction and employee retention.
Reconsidering Power and Legitimacy in Technical Communication

This article considers how issues of power and legitimacy in technical communication are connected to clearly defining what a technical communicator does. An articulation of what technical communicators do can grant the field power in presenting a united front to employers with respect to the value technical communicators bring to the workplace. So as to leverage the power and legitimacy associated with articulating what technical communicators do, this article reviews and revises the Bureau of Labor Statistics Occupational Outlook Handbook (OOH)'s definition of technical communicator. To effectively revise the OOH's definition, this article reviews academic and practitioner scholarship in technical communication and the administration of technical and professional writing programs. It demonstrates that concerns about practical skills, conceptual skills, and flexibility are related to legitimacy and power. These concerns can be used as criteria to evaluate and revise the OOH's definition of technical communicator. In closing, the article discusses the benefits associated with the revised definition and how these benefits are related to issues of power and legitimacy in the field.
A new mathematical method for quantifying trajectory of buoyant line source gaseous fuel jet diffusion flames in cross air flows

The gas leakage from a gaseous fuel pipeline usually leads to a jet fire, which causes both enormous loss of energy and thermal threat to the surrounding objects. The potential wild fire risk is a significant issue and need to be paid sufficient attention. This paper investigates the vertical flame height, horizontal flame length and provides a new mathematical method to quantify the trajectory of the flame produced by a linear buoyant turbulent jet fire, which can be resulted in due to pipeline fuel leakage, in cross air flows. Experiments are carried out by a 2 mm (width) 142.5 mm (length) line source nozzle employing propane as fuel. The velocities of cross air flows are ranged from 0 m/s to 2.5 m/s. It is found that the vertical flame height and horizontal flame length can be well predicted by initial momentum ratio (r) and Froude number (Fr) A simple and easily applied explicit mathematical method is proposed to predict the trajectory length based on circumference approximation. All these findings can contribute to both combustion science and providing guidance for the wild jet fire risk assessment.
The effect of soot modeling on thermal radiation in buoyant turbulent diffusion flames

Radiative impact of buoyant turbulent diffusion flames is the driving force in fire development. Radiation emission and re absorption is controlled by gaseous combustion products, mainly CO2 and H2O, and by soot. Relative contribution of gas and soot radiation depends on the fuel sooting propensity and on soot distribution in the flame. Soot modeling approaches incorporated in big commercial codes were developed and calibrated for momentum dominated jet flames, and these approaches must be re evaluated when applied to the buoyant flames occurring in fires. The purpose of this work is to evaluate the effect of the soot models available in ANSYS FLUENT on the predictions of the radiative fluxes produced by the buoyant turbulent diffusion flames with considerably different soot yields. By means of large eddy simulations, we assess capability of the Moss Brooks soot formation model combined with two soot oxidation submodels to predict methane and heptane fuelled fires, for which radiative flux measurements are available in the literature. We demonstrate that the soot oxidation models could be equally important as soot formation ones to predict the soot yield in the overfire region. Contribution of soot in the radiation emission by the flame is also examined, and predicted radiative fluxes are compared to published experimental data.
Oscillation frequency of buoyant diffusion flame in cross wind

Phenomenological studies relating to the oscillation of buoyant diffusion flames are very important to design flare systems in the energy and petrochemical industry or develop an image recognition algorithm for wind aided fire detection. In this work, the oscillation frequency for the "down wash mode" buoyant diffusion propane flames (momentum flux ratio of jet to cross wind 5 2 10 2 4 were investigated. The experiments were conducted in a wind tunnel, and a kinematic model of the global oscillation frequency was established. The results show that: With the increasing cross wind velocity, the flames bases are augmented by the "friction force" to cover more area of the near wake of the nozzle, with more length and area of the continuous regions of the flame. Coupling the influences of buoyancy acceleration, entrainment deceleration and "friction force" on the axial fuel velocity, the formula of the puffing frequency was deduced through introducing a buoyancy and friction force related coefficient and a decay coefficient that employs the entrainment deceleration of the axial velocity. This model was validated by the experimental results with good agreements. The flame frequency increases with increasing velocity ratio of cross wind to jet flow. The decay coefficient is less than unity, ensuring longer flow times, enabling the theoretical model to have a good predictive capability.
Viral evasion of intracellular DNA and RNA sensing
Venue: Nature Reviews Microbiology

The co evolution of viruses with their hosts has led to the emergence of viral pathogens that are adept at evading or actively suppressing host immunity. Pattern recognition receptors (PRRs) are key components of antiviral immunity that detect conserved molecular features of viral pathogens and initiate signalling that results in the expression of antiviral genes. In this Review, we discuss the strategies that viruses use to escape immune surveillance by key intracellular sensors of viral RNA or DNA, with a focus on RIG I like receptors (RLRs) cyclic GMP AMP synthase (cGAS) and interferon g (IFNg) inducible protein 16 (IFI16) Such viral strategies include the sequestration or modification of viral nucleic acids, interference with specific post translational modifications of PRRs or their adaptor proteins, the degradation or cleavage of PRRs or their adaptors, and the sequestration or relocalization of PRRs. An understanding of viral immune evasion mechanisms at the molecular level may guide the development of vaccines and antivirals.
Viral Evasion Strategies in Type I IFN Signaling A Summary of Recent Developments
Venue: Front. Immunol.

The immune system protects the organism against infections and the damage associated with them. The first line of defense against pathogens is the innate immune response. In the case of a viral infection, it induces the interferon (IFN) signaling cascade and eventually the expression of type I IFN, which then causes an antiviral state in the cells. However, many viruses have developed strategies to counteract this mechanism and prevent the production of IFN. In order to modulate or inhibit the IFN signaling cascade in their favor, viruses have found ways to interfere at every single step of the cascade, for example, by inducing protein degradation or cleavage, or by mediate protein polyubiquitination. In this article, we will review examples of viruses that modulate the IFN response and describe the mechanisms they use.

It provides important and better tools in comparing between firms in their pursuit to achieve their targets in the face of other competitors. In this context, the main aim of the study is to investigate the main structure of the six sigma approach and its characteristics and to analyze the effects of six sigma approach on the firm's performance indicators by considering a firm benefiting efficiently from six sigma approach and operating in the white goods sector in Turkey.
Off pump versus on pump coronary artery bypass grafting surgery in high risk patients: PRAGUE 6 trial at 30 days and 1 year.
Venue: Biomedical papers of the Medical Faculty of the University Palacky, Olomouc, Czechoslovakia

Off pump coronary artery bypass graft surgery (OPCAB) is an established alternative to on pump surgical revascularization. Previous studies in patients with low or intermediate risk showed no significant differences between off pump and on pump surgical revascularization. The aim of this study was to compare the two techniques in patients with high operative risk.  PRAGUE 6 is a prospective randomized single center study of 206 patients, with an additive EuroSCORE 6, scheduled for isolated coronary surgery: Group A on pump (n 108) versus Group B off pump (n 98) The primary outcome was a combined endpoint of all cause deaths, stroke, myocardial infarction, or renal failure requiring new hemodialysis, within 30 days and 1 year after randomization. All data were analyzed using the "intention to treat" principle.  Early postoperative myocardial infarction was detected in 12.1% (A) vs. 4.1% (B) of patients (P 0.048, hazard ratio 0.32, 95% CI 0.11 0.99) There was a significantly higher incidence of primary combined end point in group A (20.6% vs. 9.2% P 0.028, HR 0.41, 95% CI 0.19 0.91) in the first 30 days, but not after 1 year (30.8% vs. 21.4% P 0.117, HR 0.65, CI 0.37 1.12) CONCLUSION Off pump surgical revascularization in patients with high operative risks can significantly reduce the incidence of major postoperative complications during the first 30 days. There was no statistically significant difference in the incidence of these complications after 1 year.
State of the Art Report in Web based Visualization
Venue: Comput. Graph. Forum

In this report, we review the current state of the art of web based visualization applications. Recently, an increasing number of web based visualization applications have emerged. This is due to the fact that new technologies offered by modern browsers greatly increased the capabilities for visualizations on the web. We first review these technical aspects that are enabling this development. This includes not only improvements for local rendering like WebGL and HTML5, but also infrastructures like grid or cloud computing platforms. Another important factor is the transfer of data between the server and the client. Therefore, we also discuss advances in this field, for example methods to reduce bandwidth requirements like compression and other optimizations such as progressive rendering and streaming. After establishing these technical foundations, we review existing web based visualization applications and prototypes from various application domains. Furthermore, we propose a classification of these web based applications based on the technologies and algorithms they employ. Finally, we also discuss promising application areas that would benefit from web based visualization and assess their feasibility based on the existing approaches.

Venue: 2016 International Conference on Industrial Informatics Computing Technology, Intelligent Technology, Industrial Information Integration (ICIICII)

In order to assess crowd risk involved with mass of people gathering in large gathering spots, four common crowd flows including two way flow, heterogeneous crowd flow, circular flow and arching phenomenon were specifically analyzed on the basis of investigation of crowd's route selection. The formation mechanism of crowd risk consists of four stages namely free movement, retention, congestion and stampede, and by using the method of event tree, the important impact of crowd flow on crowd risk was found out. Combined with crowd risk model, the thinking of computer simulation on crowd risk was proposed to provide a reference for crowd security management in large gathering spots.
