Recurrent Network Models of Sequence Generation and Memory
Venue: Neuron

Sequential activation of neurons is a common feature of network activity during a variety of behaviors, including working memory and decision making. Previous network models for sequences and memory emphasized specialized architectures in which a principled mechanism is pre wired into their connectivity. Here we demonstrate that, starting from random connectivity and modifying a small fraction of connections, a largely disordered recurrent network can produce sequences and implement working memory efficiently. We use this process, called Partial In Network Training (PINning) to model and match cellular resolution imaging data from the posterior parietal cortex during a virtual memory guided two alternative forced choice task. Analysis of the connectivity reveals that sequences propagate by the cooperation between recurrent synaptic interactions and external inputs, rather than through feedforward or asymmetric connections. Together our results suggest that neural sequences may emerge through learning from largely unstructured network architectures.
Multiple Criteria Decision Analysis for Health Care Decision Making An Introduction: Report 1 of the ISPOR MCDA Emerging Good Practices Task Force.
Venue: Value in health the journal of the International Society for Pharmacoeconomics and Outcomes Research

Health care decisions are complex and involve confronting trade offs between multiple, often conflicting, objectives. Using structured, explicit approaches to decisions involving multiple criteria can improve the quality of decision making and a set of techniques, known under the collective heading multiple criteria decision analysis (MCDA) are useful for this purpose. MCDA methods are widely used in other sectors, and recently there has been an increase in health care applications. In 2014, ISPOR established an MCDA Emerging Good Practices Task Force. It was charged with establishing a common definition for MCDA in health care decision making and developing good practice guidelines for conducting MCDA to aid health care decision making. This initial ISPOR MCDA task force report provides an introduction to MCDA it defines MCDA; provides examples of its use in different kinds of decision making in health care (including benefit risk analysis, health technology assessment, resource allocation, portfolio decision analysis, shared patient clinician decision making and prioritizing patients' access to services) provides an overview of the principal methods of MCDA; and describes the key steps involved. Upon reviewing this report, readers should have a solid overview of MCDA methods and their potential for supporting health care decision making.
Using Open Research Data for Public Policy Making: Opportunities of Virtual Research Environments
Venue: 2016 Conference for E Democracy and Open Government (CeDEM)

Governments and publicly funded research organisations increasingly make research data available openly. Researchers can use this data in Virtual Research Environments (VREs) to conduct multidisciplinary data driven research and to obtain new insights potentially for governmental policy making. However, the requirements for such a VRE are not yet clear. The objective of this study is to elicit and define requirements for a multidisciplinary VRE that integrates Open Government Data (OGD) and open research data for public policy making. Based on a VRE case study, we elicit 13 VRE requirements related to data storage, data accessing, data curation and other aspects, and describe a use case of open data for governmental policy making. Meeting the requirements results in a VRE that 1) overlays the existing e Research Infrastructures to provide researchers with integrated open data from different domains, 2) offers OGD in combination with data from publicly funded research, and 3) stimulates innovation and research collaboration.
Understanding Financial Management A Practical Guide

Three general perspectives for evaluating risk in capital budgeting are a single project, a company, and a shareholders' perspective. The single project perspective assesses an investment's total risk as a stand alone unit. The company perspective considers each project according to its contribution to the firm's total risk. This perspective focuses on diversification and portfolio effects. The shareholders' perspective views each project according to its contribution to the riskiness of a diversified shareholder's portfolio. This perspective focuses on market risk.

African Generation Y students perceived personal financial management skills

Effective personal financial management is of great importance, especially in a world where individuals are faced constantly with financial risks and uncertainties regarding their financial future. However, in order to plan effectively, control and manage financial risks and opportunities in the future, as well as enjoy personal financial satisfaction, it is essential that individuals be equipped with the necessary personal financial management skills. This article reports on a study undertaken to determine African Generation Y students' perceived personal financial management skills in the South African context. In South Africa, the Generation Y cohort, labelled as individuals born between 1986 and 2005, accounted for an estimated 32 percent of the country's total population in 2015, of which the African portion made up a projected 84 percent of this cohort. A quantitative research approach was used, whereby a structured, self administered questionnaire was employed to collect data from a non probability convenience sample of 500 African Generation Y students across two South African public higher education institutions' campuses located in the Gauteng province to determine their perceived personal financial management skills. The findings suggest that African Generation Y students perceive themselves as being skilled in personal financial management. Through better understanding students' perceived personal financial management skills, the results of this study may aid in creating awareness of certain shortfalls in African Generation Y individuals' personal financial management
The impact of customer relationship management and internal marketing on business performance: a comparison of lodging industries

This study created a relationship model to explore the impact of customer relationship management (CRM) and internal marketing on relationship management and business performance in three sectors of the lodging industry. We conducted a survey in 231 bed and breakfast (B&B) establishments as well as 240 hotels and 114 motels. Our results indicate that CRM and internal marketing both have a direct impact on relationship management and an indirect effect on business performance. CRM was shown to be particularly effective, with a direct effect on financial as well as nonfinancial performances in B&Bs and hotels. In addition, internal marketing strategies were shown to have a direct effect in enhancing both financial and nonfinancial performances in B&Bs, hotels, and motels. Nonetheless, differences were observed among the three types of lodging establishments with regard to the strength of relationship paths.
Sind hohere Preise fur grossere Kopfdurchmesser in der Huftendoprothetik medizinokonomisch vertretbar? Eine Analyse der Kosten und Effekte in Deutschland

In der Huftendoprothetik stellte der Kopfdurchmesser bisher keinen Parameter dar, dessen Wiederherstellung bei der Rekonstruktion von Biomechanik und Gelenkgeometrie angestrebt wird. Neben kontroversen Diskussionen uber Vor und Nachteile groserer Kopfe scheinen deren meist hohere Kosten eine wesentliche Ursache fur einen bisher begrenzten Einsatz darzustellen. Das Ziel dieser Studie bestand darin, die Preisstruktur von Endoprothesenkopfen im Vergleich zu anderen Huftendoprothesenkomponenten zu analysieren. Daruber hinaus sollte die Verteilung realisierbarer Kopfdurchmesser an einem grosen Patientenkollektiv als Basis fur eine Mischkalkulation ermittelt werden.  Von 2 grosen deutschen Endoprothesenherstellern wurden die Relativpreise verschiedener Endoprothesenkomponenten (Pfannen, Inlays, Schafte und Kopfe) unter besonderer Berucksichtigung der verschiedenen Grosen und Varianten einer Serie erhoben und analysiert. Ein groses mit Huftendoprothesen versorgtes Patientenkollektiv wurde bez. der implantierten Pfannendurchmesser und der somit theoretisch realisierbaren Kopfdurchmesser ausgewertet. Ergebnisse: Die Analyse der Preisbildung bei Huftendoprothesenkomponenten von 2 Herstellern ergab jeweils identische Preise fur Pfannen Inlay und Schaftimplantatgrosen einer Serie. Im Gegensatz dazu lagen die Preise fur Endoprothesenkopfe mit 36 44 mm Durchmesser in Relation zu 28 mm Kopfen um 11 50 hoher, wahrend identische Preise die Ausnahme darstellten. Die Verteilung der Kopfdurchmesser bei 2719 HTEP Implantationen zeigte erhebliche Abweichungen zwischen den real eingesetzten und den theoretisch moglichen Kopfen. Schlussfolgerungen: Angesichts der nachgewiesenen Vorteile und der losbaren Nachteile groserer Kopfe in der Huftendoprothetik sollte die gegenwartige Praxis der Preisbildung mit hoheren Preisen fur grosere Durchmesser korrigiert und der bewahrten Preisbildung aller anderen Komponenten mit identischen Preisen fur alle Implantate einer Serie angeglichen werden. Damit wird es zukunftig moglich sein, bei Huftendoprothesenimplantationen im Rahmen der Rekonstruktion von Biomechanik und Gelenkgeometrie neben den Parametern Beinlange, femorales Offset und Antetorsion des Schenkelhalses auch die annahernde Wiederherstellung des Huftkopfdurchmessers anzustreben, um die Behandlungsergebnisse zu optimieren.
A dual broadband metamaterial absorber with concentric continuous and split rings resonator structure
Venue: 2016 IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics Engineering (UPCON)

This paper presents the design, simulation and parametric analysis of a concentric continuous and split rings resonator (CCRR, CSRR) structure for a dual broadband metamaterial (MM) absorber. The MM structure unit cell consists of concentric circular split rings of same width and different radii and concentric continuous rings of different width and different radii arranged in four different quadrants. The three layered proposed MM absorber design has upper layer comprising of concentric continuous and split rings structured sub cells separated by bottom laminated copper layer of FR 4 substrate. The proposed MM absorber is insensitive to any polarization state of incident EM waves due to highly symmetrical circular and split ring structures. The scattering parameter and absorption coefficient are obtained for the present MM absorber. The magnetic and electric fields are monitored to realize the behavior of MM structure. The dual broadband MM absorber has absorbance of 99% from 7.785 GHz 8.475 GHz and absorbance of 98% from 11.835 GHz 12.81 GHz. The absorption peaks for this MM absorber are obtained as 99.5% 99.6% 98.4% and 98.8% at 7.785 GHz, 8.475 GHz, 11.835 GHz and 12.81 GHz frequencies respectively for the normal incidence of EM waves. The high absorbance makes this MM absorber suitable for various microwave applications including airborne and radar signal absorption.
Measurement and modeling of pressure drop of HEPA filters clogged with ultrafine particles

The harmlessness of nanometric aerosols is currently being called into question. Their massive production in industrial production processes or during combustion, whether deliberate or incidental, requires that they be contained. Today, the most widely used means and that providing the best cost benefit ratio is the use of porous, mainly fibrous material, in air filter design. The efficiency of these filtration devices has been the subject of numerous studies and does not require further demonstration, but the prediction of their lifetime, conditioned by the pressure drop which evolves during clogging, still needs to be managed. Predicting pressure drop in the case of very thin, and therefore very clogging, particles remains a major issue in the design of filtration devices. Two phases have been highlighted on a plane fibrous medium: deep filtration and surface filtration preceded by a transition regime where particles are collected both in the depth and on the surface of the medium. Each of these phases is characterized by a different pressure drop evolution. This study focuses on measuring the porosity of the deposits, an important parameter which conditions the resistance of a clogged filter. For this, pseudo spherical alumina particles and aggregates of 10 nm carbon nanoparticles with respectively 350 nm and 73 nm of electrical mobility diameter were used. A device enabling the continuous measurement of the thickness of the deposit during the clogging process was developed. Results are shown for filtration velocities of 0.8 and 0.16 cm s 1. The change in pressure drop of a fibrous medium is then studied for deep filtration, when aerosols penetrate the medium at the beginning of the filtration process. On this basis, a simplified model was developed to predict the pressure drop increase of a filter exposed to ultrafine aerosols.
Entrepreneurial Failure: distinct perceptions among founders, employees, and investors A narrative approach for understanding the concept of entrepreneurial failure

This study explores the perception of entrepreneurial failure by different actors in entrepreneurship. Entrepreneurial failure has emerged as an important concept within entrepreneurship literature, since it might impact economic development and innovation of society. Using a qualitative study with a narrative approach, this paper analyzes perceptions of 41 founders, 28 employees, and 14 investors about new venture failure concept. The results show the existence of different perspectives concerning failure. These differing views indicate diverging goals that results in the major tensions among different groups.
A review of the National Eco Industrial Park Development Program in Korea: progress and achievements in the first phase, 2005 2010

This paper provides a comprehensive review of the first phase of the Korean National Eco Industrial Park (EIP) Development Program from 2005 to 2010. The main objectives of this review are to introduce how Korea established its own approach to nationwide eco industrial development and to examine the program's successes and limiting factors to draw lessons about how industrial symbiosis can be developed successfully elsewhere. The Korean EIP program emerged from a context of 50 years of industrial development to transform traditional industrial structures into EIPs using cleaner production at the industrial park level. During the first five years, regional EIP centers established at five pilot sites developed and implemented 47 resource sharing projects, which generated considerable economic and environmental benefits. This was possible due to an institutional system that effectively combined top down and bottom up approaches and to the mediating role of regional EIP centers, which bring together local stakeholders from businesses, governments, and research organizations. By learning during the first phase, Korea has established its own model for eco industrial development that will continue to develop during the second and third phases.
Assessing the performance of carbon dioxide emission reduction of commercialized eco industrial park projects in South Korea

Urbanization and industrialization during the 20th century caused global climate change. South Korean industrial complexes were one of the key sources of carbon dioxide (CO2) emissions as the most important cause of the climate change. South Korean government launched eco industrial park projects for cleaner production and environmentally sustainable development in 2005. To assess the performance of the commercialized eco industrial park projects in the mitigation of climate change, this study analyzed the direct CO2 emission reductions through the 41 eco industrial park projects conducted from 2005 to 2012 in South Korea. The study classified the eco industrial park projects according to their primary CO2 reduction function and analyzed the achievement of each type of project in terms of the direct CO2 emission reductions. These findings indicated that the eco industrial park projects resulted in reduction of 0.48% of CO2 emissions in 2004 from the South Korean industrial sector before the eco industrial park projects began. Most of the projects were implemented effectively through networks for the sharing and exchanging of energies and resources. Therefore, spatial development planning for the effective relationship building among nodes in the network is required. The study also identified that the performances and limitations of the eco industrial park projects varied according to the reduced fuels and wastes, the recycled by products and wastes, and locations of eco industrial parks. Therefore, eco industrial park projects should be associated with the other projects for the reduction of the CO2 emissions from other sources that cannot be reduced by eco industrial park projects alone. Furthermore, to mitigate climate change at the administrative district level, local governments should cooperate with each other to perform the projects in urban and regional planning for environmentally and economically sustainable developments. This study will help develop suitable guidelines, standards, and policies for the reduction of greenhouse gas emissions to solve environmental and economical problems in the various regions and cities in the South Korea.
SAW transformer filter
Venue: 2016 IEEE International Ultrasonics Symposium (IUS)

Low loss Surface Acoustic Wave (SAW) resonator type filters, such as double mode SAW filters (or Coupled Resonator Filters, DMS/CRF) can be considered as transformers. Such a RF SAW "transformer filter" could operate directly on one of the ISM bands and be useful, for example, in "wake up" radios, since the RF voltage can be raised by passive means prior to rectification. Here, we propose to use a CRF type of low loss filter in combination with a few special techniques to increase the output impedance/voltage. The main idea is to separate the output transducers in sections and connect the sections in series. Several variants of this SAW transformer were designed, fabricated, and measured. We have used a so called "degenerated" CRF with three long IDTs, the output transducers being subdivided into series connected sections. An estimated transformer coefficient of around 10 was achieved.

An agri food supply chain traceability system for China based on RFID blockchain technology
Venue: 2016 13th International Conference on Service Systems and Service Management (ICSSSM)

For the past few years, food safety has become an outstanding problem in China. Since traditional agri food logistics pattern can not match the demands of the market anymore, building an agri food supply chain traceability system is becoming more and more urgent. In this paper, we study the utilization and development situation of RFID (Radio Frequency IDentification) and blockchain technology first, and then we analyze the advantages and disadvantages of using RFID and blockchain technology in building the agri food supply chain traceability system; finally, we demonstrate the building process of this system. It can realize the traceability with trusted information in the entire agri food supply chain, which would effectively guarantee the food safety, by gathering, transferring and sharing the authentic data of agri food in production, processing, warehousing, distribution and selling links.
Top k Preferences in High Dimensions
Venue: IEEE Trans. Knowl. Data Eng.

Given a set of objects \mathcal {O} each with $d$ numeric attributes, a top $k$ preference scores these objects using a linear combination of their attribute values, where the weight on each attribute reflects the interest in this attribute. Given a query preference $q$ a top $k$ query finds the $k$ objects in \mathcal {O} with highest scores with respect to $q$ Given a query object $o$ and a set of preferences \mathcal {Q} a reverse top $k$ query finds all preferences $q\in \mathcal {Q} for which $o$ becomes one of the top $k$ objects with respect to $q$ Previous solutions to these problems are effective only in low dimensions. In this paper, we develop a solution for much higher dimensions (up to high tens) if many preferences exhibit sparsity i.e. each specifies non zero weights for only a handful (say $5$ $7$ of attributes (though the subsets of such attributes and their weights can vary greatly) Our idea is to select carefully a set of low dimensional core subspaces to "cover" the sparse preferences in a workload. These subspaces allow us to index them more effectively than the full dimensional space. Being multi dimensional, each subspace covers many possible preferences; furthermore, multiple subspaces can jointly cover a preference, thereby expanding the coverage beyond each subspace's dimensionality. Experimental evaluation validates our solution's effectiveness and advantages over previous solutions.
