How do we use the data from pre-analytical quality indicators and how should we?

It is impossible to imagine a modern medical laboratory without a structured quality management system in place. Nevertheless, this system usually focuses mostly on the analytical part of the total testing process (TTP), despite being aware of the fact that most errors occur in the pre- and post-analytical phases. There are many reasons possibly explaining this fact, one of them being that extra-analytical processes are hard to grasp, since they occur mostly outside of the laboratory and include many different parties. Despite these obstacles, it is mandatory to keep all steps of TTP, potentially influencing the analytical test result or their interpretation, under meticulous quality control and to improve them as much as possible, involving all health care workers contributing to sample quality. Additionally, it is necessary to collect and evaluate all data in a standardized manner, not only within one laboratory, but nationwide and internationally. This is a perquisite for valid data comparison over time (trend analysis) and benchmarking, the basis for threshold definition and continuous improvement. A widely accepted method to meet all these requirements is the concept of quality indicators (QIs). In this review, we provide an overview over this topic and we discuss an easy to use and freely available tool, aiming to aid laboratories in data collection and comparison: The QIs project of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Working Group on “Laboratory errors and patient safety” (WG-LEPS). Additionally, we provide practical suggestions on how to successfully implement QIs within any laboratory.
HOEK-BROWN FAILURE CRITERION - 2002 EDITION

The Hoek-Brown failure criterion for rock masses is widely accepted and has been applied in a large number of projects around the world. While, in general, it has been found to be satisfactory, there are some uncertainties and inaccuracies that have made the criterion inconvenient to apply and to incorporate into numerical models and limit equilibrium programs. In particular, the difficulty of finding an acceptable equivalent friction angle and cohesive strength for a given rock mass has been a problem since the publication of the criterion in 1980. This paper resolves all these issues and sets out a recommended sequence of calculations for applying the criterion. An associated Windows program called "RocLab" has been developed to provide a convenient means of solving and plotting the equations presented in this paper.
3D semantic labeling of ALS point clouds by exploiting multi-scale, multi-type neighborhoods for feature extraction

The semantic labeling of 3D point clouds acquired via airborne laser scanning typically relies on the use of geometric features. In this paper, we present a framework considering complementary types of geometric features extracted from multi-scale, multi-type neighborhoods to describe (i) the local 3D structure for neighborhoods of different scale and type and (ii) how the local 3D structure behaves across different scales and across different neighborhood types. The derived features are provided as input for several classifiers with different learning principles in order to show the potential and limitations of the proposed geometric features with respect to the classification task. To allow a comparison of the performance of our framework to the performance of existing and future approaches, we evaluate our framework on the publicly available dataset provided for the ISPRS benchmark on 3D semantic labeling.
Hypothesized performance on complex tasks as a function of scaled instructional strategies

The author identifies a set of instructional strategy principles that have been prescribed by a number of different instructional theories and recommended practices. He then proposes a set of hypotheses for the interrelationships among these principles. While many of these instructional design principles have been supported by individual experimental studies the author has been unable to find an integrated body of research that has studied the interrelationships among these instructional principles. The hypotheses proposed in this paper are designed to provide a framework for integrated research on instructional strategies. Perhaps this paper might serve as a catalyst for dissertations and other research activities in the science of instruction.
Single channel properties of recombinant GABA A receptors containing ã 2 or ä subtypes expressed with á 1 and â 3 subtypes in mouse L 929 cells

fast inhibitory synaptic transmission in the central nervous system (CNS). GABARs are composed of pentameric combinations of á(1—6), â(1—4) and ã(1—4) or ä(1) subunit subtypes. Both â4 and ã2 subtypes have splice variants. The properties of GABARs depend upon their subunit and subtype composition (Sieghart, 1995). While the stoichiometry of GABARs has not been clearly determined, it is likely that most native GABARs are composed of combinations of á, â and either ã or ä subtypes. The regional expression of ã and ä subunit mRNAs in the mammalian brain is different, suggesting different roles for ã and ä subtype-containing GABARs. Messenger RNA for the ã subunit is widely expressed, with at least one subtype appearing in most brain regions and throughout development in the rat, while expression of mRNA for the ä subunit is more restricted, appearing principally in discrete regions of the post-natal rat brain; the hippocampal dentate gyrus, cerebellar granule cell layer and some regions of the thalamus (Shivers et al. 1989; Wisden, Laurie, Monyer & Seeburg, 1992; Laurie, Seeburg & Wisden, 1992a; Laurie, Wisden & Seeburg, 1992b). Structurally, ã and ä subunits share about 35% sequence similarity, about the same as between other GABAR subunit families (Shivers et al. 1989).
Independent variables Dependent variable Ho : 1 Ho : 2 Ho : 3 Ho : 4 Ho : 5 Ho

This study devises a model to evaluate the strength of auditing standards and reporting (SARS) in individual countries. Drawing from data collected by the World Economic Forum the model’s predictive capabilities are tested in the geographical region of sub-Saharan Africa. Data from 28 countries was utilised. The predictive powers of the model are significant. Eight of the thirteen variables utilised were found to be significant predictors of a country’s SARS. Corporate governance variables and shareholder protection variables were found to be particularly prominent. Evaluation of the results also demonstrates that a country’s SARS does not appear to be linked to adoption of international standards of auditing. This suggests standardised adoption of ISAs will not necessarily lead to uniformly strong and consistent audit reporting regimes across countries.

Grid frequency fluctuations with the issue of high wind power penetration

Now a day's worldwide energy problem is one of the great problems. Wind energy, a renewable and environmental friendly, is an important source of electrical power in recent years. As wind turbine output is proportional to the cube of wind speed, the wind turbine generator output fluctuates due to wind speed variations and highly variable at several different timescales from hour to hour, daily, and seasonally, can have an influence on the power system frequency. This paper investigates the influence of the ratio of the wind generator capacity to the power system capacity, on the power system frequency. To do this, impacts of thermal and hydro governor control system models are presented to show the performance of single synchronous generator. This study will be helpful for taking preventive measures for the power grid companies to improve the stability and quality of electric power. Simulation analyses have been carried out to investigate the performance of the power system frequency with the increased wind power penetration using real wind speed data. The wind speed data used in the analysis is the real data, which is measured in Hokkaido Island, Japan. The simulation analyses have been performed by using PSCAD/EMTDC.
The origins of electromechanical indentation size effect in ferroelectrics

Metals exhibit a size-dependent hardening when subject to indentation. Mechanisms for this phenomenon have been intensely researched in recent times. Does such a size effect also exist in the electromechanical behavior of ferroelectrics? —if yes, what are the operative mechanisms? Our experiments on BaTiO3 indeed suggest an elastic electromechanical size effect. We argue, through theoretical calculations and differential experiments on another nonferroelectric piezoelectric (quartz), that the phenomenon of flexoelectricity (as opposed to dislocation activity) is most likely responsible for our observations. Flexoelectricity is the coupling of strain gradients to polarization and exists in both ordinary and piezoelectric dielectrics. In particular, ferroelectrics exhibit an unusually large flexoelectric response.
The potential use of lipases in the production of fatty acid derivatives for the food and nutraceutical industries

The potential of lipases (E.C.3.1.1.3.) as biocatalysts for the production of fatty acid derivatives for the food and nutraceutical industries, such as flavouring esters, fatty acid esters of antioxidants and structured lipids, is enormous, mainly due to their high regio- and stereo-selectivities, in addition to the other well-known advantages of enzymatic processes. The replacement of chemical catalysts by lipases presents great benefits in terms of the nutritional properties of the obtained products and environmental care. The reactions performed for the production of these compounds, as well as the best operation conditions, the biocatalysts used, reactor types and operation mode, are addressed in this review.
Low Pressure (Hypobaric) Storage of Avocados1

‘Waldin’, ‘Booth 8’, and ‘Lula’ avocados (Persea americana Miller) were not acceptable when softened at 21.1 °C in air under normal pressure, if they had been stored for 4–6 weeks at 7.2-10.0°, 98-100% relative humidity, and an atmospheric pressure of 76, 152, or 760 mm Hg. ‘Waldin’ avocados were acceptable when softened after 25 days at 7.2°C and 91 mm Hg provided that storage was in 2% O2 and 10% CO2. The results suggest that atmospheres both low in O2 and high in CO2 are necessary for the successful storage of avocados under low pressure. Under these conditions the low pressure system is comparable to the standard controlled atmosphere system in which avocados are stored in 2% O2 and 10% CO2 at normal atmospheric pressure.
Estimating the Relationship between Employer-Provided Health Insurance, Worker Mobility, and Wages

In this paper, a joint model of wages, hazard of a job ending, and probability of holding employer-provided health insurance is estimated, taking account of unobservable person and job characteristics. A unique data source, the 1990 and 1996 SIPP Panels linked to SSA administrative job histories, enables the identification of random person and job effects and the correlation of these effects across the three equations. The explicit modeling of this correlation produces consistent estimates of the effect of tenure on wages and the effect of health insurance on mobility. Substantial levels of job-lock and significant annual returns to seniority are found. Increasing the job-specific probability of obtaining employerprovided health insurance from 60% to 63%, or increasing the job-specific hourly wage rate by $. 80, are both associated with an equivalent decrease in the hazard of the job ending. However, the dollar value of the wage benefit is substantially higher.
Proceedings Chapter Reference Contexts and Composite Objects

Many applications require the capability to define and manipulate a collection of related objects as a single unit. Object-oriented database models and systems usually provide the concept of composite object for that purpose. The concept of context that we propose here provides another, more general, way to view and manipulate collections of objects. We compare the two concepts both in their formal definitions and in their implementation in object-oriented database system. FALQUET, Gilles, LEONARD, Michel Paul, AL-JADIR, Lina.

Analysis of Circularly Polarized Dielectric Resonator Antenna Excited by a Spiral Slot

The hemispherical dielectric resonator antenna (DRA) excited by a single-arm spiral slot is studied theoretically in this paper. The Green’s function technique is employed to formulate an integral equation for the spiral slot current. The moment method with piecewise sinusoidal (PWS) basis and testing functions is used to convert the integral equation into a matrix equation by using a deltagap exciting source. The input impedance, return loss, axial ratio and radiation pattern are calculated. Numerical results demonstrate that the analysis is efficient.
Relationship between Store Loyalty and Shopping Behavior: A Conceptual Study

The primary focus of this paper is to measure the relationship among the three constructs Consumer Self Concept, Store Loyalty and Shopping Behavior. The paper is the beginning of the doctoral study and concentrating on the conceptual mapping of idea. For this paper the extensive literature review is the base and the concept derived from the secondary sources only. The effort is expected to give an insight of the problems and would attempt to suggest the importance of Self Concept & Store Image congruity’s role in generating Store Loyalty. This in turn greatly impacts shopping behavior too. The paper seeks to understand the role of Brands that the store carries on the resultant impact on Store Loyalty, Seek to extend our understanding of the impact of self-concept congruity by assessing the relative effects of two types of congruity variables on brand commitment, trust and retail loyalty. The role of Brand & Trust works as mediating variables in shaping Store Image & thus Store Loyalty and to devise marketing strategies for retailers i.e. seek to change consumer’s reaction to a store favorably or re-position the images of the stores to the self-image of the target group of consumers. Key Words: Consumer, Self Concept, Store Loyalty, Shopping Behavior, Store Image.
Multi View Point Measure for AchievingHighest Intra-Cluster Similarity

Clustering is one of the data mining techniques which has important utility in real time applications. Cluster is a group of objects with highest similarity. The result of clustering can be used further in many applications including query processing. Clustering can also be used in text mining. The clustering algorithms that are available in this domain uses single viewpoint to find the similarity between object. But, the singe view point similarity measure cannot have highly informative assessment of similarities. In this paper we propose to implement a novel measure known as multiviewpoint based similarity measure. It will consider multiple-viewpoints while measuring similarity which facilitates highly informative assessment of similarity. We built a prototype application to demonstrate the conceptual proof. The empirical results revealed that the measure is effective.
Cycling and public transportation sharing space: An option to increase cycling ridership

Compartir los carriles exclusivos de buses con ciclistas es una buena alternativa para fomentar el transporte publico y el ciclismo dentro de ciudades consolidadas, ya que permite proveer una infraestructura para ciclismo en lugares en donde por el limitado ancho de via no es posible proveer una infraestructura independiente. Combinar dos modos de transporte en el mismo espacio genera otras preocupaciones, por lo que el diseno de un carril compartido ademas de asegurar eficiencia debe precautelar la integridad de los ciclistas. La falta de un estandar para el diseno de carriles compartidos para buses y bicicletas ha limitado la implementacion de estos en ciudades de paises en desarrollo que generalmente carecen de recursos economicos y tecnicos para emprender investigacion. El analisis de algunas normativas utilizadas en Europa, Norte America y Australia para el diseno de carriles compartidos entre buses y ciclistas coinciden en que el tipo de infraestructura para bicicletas y su alineacion dentro del carril compartido, asi como el ancho del carril, son los parametros que principalmente deben considerarse para garantizar la seguridad y la eficiencia de estos dos modos. La revision del sistema de movilidad en buses y bicicletas en Paris muestra que el incremento del uso de transporte publico y de la bicicleta depende no solo de la calidad de la infraestructura construida, sino sobre todo de la coordinacion entre el diseno, operacion y control del uso adecuado de dichas estructuras y de las medidas implementadas para desfavorecer el uso del vehiculo privado.
Student health and well-being in secondary schools: the role of school support staff alongside teaching staff

ABSTRACT A growing evidence base indicates that health and educational attainment are synergistic goals. Students’ relationships with teachers and other students in the school environment are consistently predictive of a broad range of health and well-being outcomes. Despite the potential importance of relationships between students and a broad range of actors within a school, research tends to reduce ‘school staff’ to ‘teachers’. Previous research has highlighted incongruence between the power imbalance within a teacher–student relationship and the dynamics required to address health and well-being-related issues. To date, there has been no investigation into how the nature of the relationships between students and support staff may differ from those with teaching staff. This article aims to conceptualise the role of support versus teaching staff in promoting health and well-being to understand how school system functioning may affect relationships between school staff and students. Semi-structured interviews were conducted to obtain the perceptions of staff, students and parents within four exploratory case study schools of differing socio-economic status, geographical location and size. In line with the Theory of Health Promoting Schools and Human Functioning, findings demonstrated that the prominence of well-being relies on provision of staffing structures which include a team of support staff to work alongside teaching staff to provide the time and space to deal with issues immediately and build trust and rapport in a one-to-one setting. Further mixed-methods research is required to investigate how staffing structures can facilitate the development of mutually trusting relationships between staff and students.
Open innovation and supply chain management in food machinery supply chain: a case study

Supply chains continue to growth in complexity, including numerous echelons and numerous players per echelon. Consequently, a company needs to integrate its activities with suppliers and customers, in order to survive. Innovation is a typical example of activity that a company should share with suppliers and customers. In particular, over the last few years, a specific concept of “open innovation” has been paving the way in the innovation management field. This paradigm describes a new approach to internal R&D management, which assumes that firms can and should use external ideas and internal ones, as well as internal and external paths to market, as they look to advance their technology. The aim of this paper is to provide insights toward open innovation practices in a specific supply chain, the food machinery one, moved by the consideration that there is little empirical evidence of open innovation strategies within this context. By means of case studies and semi-structured interviews, we examine a three-echelon supply chain, thus providing a picture of the adoption of open innovation in the food machinery industry. Results show that the actors that more adopt this new paradigm are manufacturer and customer, although all the three actors investigated agreed in defining the benefits derived from innovation and open innovation mechanisms. From this study, theoretical and practical implications can be derived and transferred to the whole food machinery industry.

Theory of fission for two-component lipid vesicles

The coupling between Gaussian curvature and local lipid composition for two-component lipid vesicles can destabilize the narrow neck in a budding transition. Such a coupling reduces the Gaussian rigidity of a membrane and enhances the fission transition if the minor component lipids prefer to stay at regions with large positive Gaussian curvature. On the other hand, it increases the Gaussian rigidity and a fusion transition is enhanced if the minor component lipids are expelled from regions with large positive Gaussian curvature.
Effects of Antenna Characteristics in RFID Systems for Positioning Purposes

Radio Frequency Identification (RFID) is a wireless system designed to identify the presence of objects attached by tags. In recent times, RFID is also used for positioning purposes. We show a scenario of wireless propagation observed by eight antennas with different polarization located in different positions. In this way, the antenna characteristics, i.e. the polarization and diagram radiation of the antennas will play a significant role in producing electromagnetic field in the region. In this work we will use the fingerprinting procedure, with this we produce some data bases containing the electric field received by RFID readers if we located the RFID tag in certain position in region of interest. In this work, two cost functions are proposed, which are to be minimized for determining the position of the tag.
