The impact of rater agreeableness and rating context on the evaluation of poor performance

We tested the effects of rater agreeableness on the rating of others’ poor performance in performance appraisal (PA). We also examined the interactions between rater agreeableness and two aspects of the rating context: ratee self-ratings and the prospect of future collaboration with the ratee after the feedback of PA ratings. Participants were government employees (N = 230) allocated to one of six experimental groups (a 3 × 2 between-groups design) or a control group (n = 20). Participants received accurate, low-deviated or high-deviated self-ratings from the ratee. Half were notified they would collaborate with the ratee in a future task. High rater agreeableness, positive deviations in self-rating, and the prospect of future collaboration were all independent predictors of higher PA ratings. The interactions between rater agreeableness and rating context were very small and inconsistent. We argue that conflict avoidance is an important motivation for those rating the performance of others.

Argumentation-based Security for Social Good

The increase of connectivity and the impact it has in every day life is raising new and existing security problems that are becoming important for social good. We introduce two particular problems: cyber attack attribution and regulatory data sharing. For both problems, decisions about which rules to apply, should be taken under incomplete and context dependent information. The solution we propose is based on argumentation reasoning, that is a well suited technique for implementing decision making mechanisms under conflicting and incomplete information. Our proposal permits us to identify the attacker of a cyber attack and decide the regulation rule that should be used while using and sharing data. We illustrate our solution through concrete examples.
Acetic Acid Enhanced Narrow Band Imaging for the Diagnosis of Gastric Intestinal Metaplasia

Gastric intestinal metaplasia (GIM) is a precancerous lesion of the stomach. The detection of GIM using conventional white-light endoscopy (WLE) is difficult. In this study, we determined whether acetic acid-enhanced narrow band imaging (AA-NBI) improves the detection of GIM. A consecutive cohort of 132 individuals aged 40 years or older was subjected to upper gastrointestinal endoscopy using WLE, NBI and AA-NBI. The ability of the three methods to diagnose GIM in patients was compared. Histological assessment (per-patient and per-biopsy) was used for the accuracy assessment. Sixty-six (50.0%) out of the 132 individuals examined were found to have GIM, of which 44 (66.7%) were diagnosed correctly by NBI (sensitivity 66.7% and specificity 68.2%) and 58 (87.9%) were correctly identified by AA–NBI (sensitivity 87.9% and specificity 68.2%), as compared to only 22 (33.3%) by WLE (sensitivity 33.3% and specificity 28.8%). Therefore, the sensitivity of AA–NBI in the diagnosis of GIM was significantly higher than NBI (p<0.05) and WLE (p < 0.001). Our study indicates that AA-NBI can improve the accuracy of endoscopy-targeted biopsies for GIM.
Birth of a normal girl after in vitro fertilization and preimplantation diagnostic testing for cystic fibrosis.

BACKGROUND Cystic fibrosis is a common, severe autosomal recessive disease caused in a majority of cases by a three-nucleotide deletion (delta F508) in the cystic fibrosis transmembrane regulator gene. Current methods of prenatal diagnosis involve chorionic-villus sampling or amniocentesis. In vitro fertilization and diagnosis during embryonic development before implantation would allow only unaffected embryos to be selected for transfer to the uterus, thereby avoiding the need to terminate a pregnancy. METHODS Preimplantation diagnosis of cystic fibrosis was attempted in the cases of three couples, both members of which carried the delta F508 deletion. In vitro fertilization techniques were used to recover oocytes from each woman and fertilize them with her husband's sperm. Three days after insemination, embryos in the cleavage stage underwent biopsy and removal of one or two cells for DNA amplification and analysis. RESULTS Only two oocytes from one woman were fertilized normally; DNA analysis of one of the embryos failed and cystic fibrosis was diagnosed in the other (i.e., it was homozygous for delta F508), so neither was transferred. The oocytes of each of the other two women produced noncarrier, carrier, and affected embryos. Both couples chose to have one noncarrier embryo and one carrier embryo transferred. One woman became pregnant and gave birth to a girl free of the deletion in both chromosomes. CONCLUSIONS Preimplantation diagnosis of the delta F508 deletion causing cystic fibrosis is possible through in vitro fertilization, biopsy of a cleavage-stage embryo, and amplification of DNA from single embryonic cells. This approach should be equally applicable to other single-gene diseases in which the defect has been identified. Analysis of a series of pregnancies, however, will be required to assess the method adequately.
Thermal Diffusivity and Thermal Conductivity of Epoxy-Based Nanocomposites by the Laser Flash and Differential Scanning Calorimetry Techniques

Nanocomposites were fabricated by using a commercial two part epoxy as a matrix and multiwalled carbon nanotubes, graphite fibers and boron nitride platelets as filler materials. Multiwalled carbon nanotubes (MWCNTs) that were produced by chemical vapor deposition were found to produce nanocomposites with better thermal diffusivity and thermal conductivity than the MWCNTs that were produced by the combustion method. Compared to the MWCNTs produced by both methods and graphite fibers, boron nitride produced nanocomposites with the highest thermal conductivity. Specific heat capacity was measured by using differential scanning calorimetry and thermal diffusivity was measured by using the laser flash.
Accuracy of MoM VIE eigenmode solution obtained with edge basis functions

The edge basis functions, which are a subset of SWG basis functions, do not have artificial volume charges and require a smaller number of unknowns. The present study establishes the accuracy of the eigenmode solution for (in)homogeneous isolated dielectric resonators (DR) obtained with the edge basis functions. Special attention is paid to integration rules for calculation of the impedance matrix

Joint Registration and Segmentation of Histological Volume Data by Diffusion-Based Label Adaption

Three-dimensional serial section imaging delivers high spatial resolution and histological detail, which facilitates analysis of differentiation and development by exact labelling of tissues and cells, unknown to other 3-D imaging modalities. We propose an algorithm for interleaved reconstruction and segmentation of tissues in serial section volumes by diffusion-based registration and adaption of two-dimensional reference labellings. Iterative refinement of the global image congruence and local deformation of labellings delivers an efficient algorithm for processing of large volume data-sets. The benefits of the approach are shown by means of reconstruction and segmentation of giga-voxel serial section volumes of plant specimen.
Evaluación de estrategias de capa cruzada para el manejo eficiente de energía en redes inalámbricas de área corporal aplicadas en telemedicina

Dentro de los esquemas de comunicacion de redes inalambricas de area corporal (WBAN), se encuentran los protocolos de capa cruzada, constituidos en una novedosa opcion para alcanzar un balance efectivo entre consumo eficiente de energia y metricas de desempeno. En el presente trabajo, evaluamos el desempeno de una estrategia de capa cruzada al compararla contra los protocolos del estandar IEEE802.15. 4 en una WBAN. Se evaluo el desempeno de ambas estrategias empleando una simulacion de redes WBAN. Luego se ejecuto una comparacion estadistica y se encontro que la estrategia de capa cruzada ofrece un mejor desempeno con respecto a la compensacion entre consumo eficiente de energia y algunas metricas de desempeno en nuestra WBAN. Observamos que en general, la estrategia de capa cruzada supera a ambos modos del estandar IEEE802.15. 4 (ranurado y no-ranurado) con respecto a consumo eficiente de energia, retraso extremo a extremo, tasa de perdida de paquetes y goodput. El presente trabajo de investigacion fue realizado para optar al titulo de Magister en Ingenieria de Telecomunicaciones
Localization in paired correlated random binary alloys.

We study both analytically and numerically the electronic structure and the transport properties of binary chains, when the site energies (e A or e B ) are random in pairs. We compute the density of states and the localization length versus energy for various strengths of disorder by considering products of 2×2 random matrices in the microcanonical ensemble and also within the usual canonical-ensemble method. The limiting cases of AA,BB correlation, which favor delocalization and AB,BA anticorrelation, which favor localization, as well as intermediate cases involving all pairs AA,AB,BA,BB at random, are distinguished
Minhocário campeiro de baixo custo para a agricultura familiar.

MINHOCARIO CAMPEIRO: RESUMO:A minhocultura e uma atividade muito interessante para a producao de adubo orgânico de qualidade nas propriedades familiares. O humus de minhoca, alem de ser rico em nutrientes para as plantas, ajuda a melhorar as caracteristicas fisicas do solo, como a aeracao e a retencao de agua. Ao contrario do que grande parte dos agricultores pensa, a principal causa do insucesso de um minhocario esta em seu no manejo inadequado e nao na falta de uma maior infraestrutura, feita com tijolos, telhas e cimento. O minhocario campeiro de baixo custo e construido com materiais disponiveis na propria propriedade e pode ser adaptado a diversas condicoes. Sugere-se contruir o minhocario com bambus e adotar a largura maxima de 1 metro; o comprimento pode ser variavel. Os bambus devem ser colocados intercalados um sobre o outro de forma que suas pontas se cruzem cerca de 5 cm. Para guarnecer as pontas, deve ser fixada uma estaca de cada lado da cruz formada na juncao. Os bambus devem ser empilhados ate atingirem a altura de 30 cm, embora esse limite possa ser maior conforme a necessidade. O fato de nao requerer o uso de arame na sua estrutura e de poder ter sua altura aumentada a qualquer momento, e o que diferencia esse minhocario de outros modelos tambem construidos com bambu. O interior do minhocario deve ser forrado com sombrite ou filme plastico perfurado, para, ao mesmo tempo, conter o alimento e as minhocas e permitir a drenagem da agua da chuva que por ventura venha a cair em seu interior. Para reduzir ao maximo o efeito do impacto da gota da chuva sobre o minhocario, deve ser colocada uma cobertura de folhas secas ou construir uma tampa com ripas de bambus cortadas ao meio e revesti-la com lona plastica. O minhocario deve ser montado em um local onde faca sombra durante a maior parte do dia. A area deve ter uma leve declividade, para que a agua da chuva ou de escorrimento nao acumule em seu interior.

The Time-Harmonic Discontinuous Galerkin Method as a Robust Forward Solver for Microwave Imaging Applications

Novel microwave imaging systems require flexible forward solvers capable of incorporating arbitrary boundary conditions and inhomogeneous background constitutive parameters. In this work we focus on the implementation of a time-harmonic Discontinuous Galerkin Method (DGM) forward solver with a number of features that aim to benefit tomographic microwave imaging algorithms: locally varying high-order polynomial field expansions, locally varying high-order representations of the complex constitutive parameters, and exact radiating boundary conditions. The DGM formulated directly from Maxwell's curl equations facilitates including both electric and magnetic contrast functions, the latter being important when considering quantitative imaging with magnetic contrast agents. To improve forward solver performance we formulate the DGM for time-harmonic electric and magnetic vector wave equations driven by both electric and magnetic sources. Sufficient implementation details are provided to permit existing DGM codes based on nodal expansions of Maxwell's curl equations to be converted to the wave equation formulations. Results are shown to validate the DGM forward solver framework for transverse magnetic problems that might typically be found in tomographic imaging systems, illustrating how high-order expansions of the constitutive parameters can be used to improve forward solver performance.
Impact of poly-crystalline diamond within power semiconductor device modules in a converter

This paper presents the finding of thermal characterization of polycrystalline diamond for power semiconductor device modules in a converter. Comparisons of measured thermal performance of two diamond demonstrators, consisting of metalized diamond tiles attached to aluminum and copper forced air cooled heat sinks; show that power dissipation can be increased from 278W to 535W when compared to commercial products operating at a case temperature of 100°C and a maximum junction temperature of 175°C. Detailed converter simulations of a two level three-phase inverter driving a 15kW permanent magnet machine shows that using diamond can increase active power density from 13kW/kg to 17kW/kg at a coolant temperature of 100oC and a flowrate of 6 liters per minute.
Chemical Ordering in Na-Pb and Na-Hg Binary Liquid Alloys

A simple model has been used to investigate the nature of chemical order in Na-Pb and Na-Hg liquid binary alloy at 700K and 673K respectively. The energy parameter obtained from the model was used to calculate the concentration dependent mixing properties such as Gibb’s free energy of mixing, Concentration fluctuations in the long wavelength limit and the Warren-Cowley chemical short range order parameter. Results obtained showed that both alloys are heterocoordinated throughout the entire concentration and there is tendency for segregation and demixing to take place in the liquid alloys. We observed that Na-Hg liquid alloy is more strongly interacting binary alloy and chemically ordered than Na-Pb liquid alloy.
Paediatric home care in the 1990s.

Home care is not a new concept. Before the emergence of scientific medicine the rich were cared for at home by their physicians, and hospitals originated as charitable institutions in which the destitute, as much as the sick, were cared for. A shift in the emphasis of hospital work from the social to the scientific began before the industrial revolution, and has accelerated during the era of the NHS. The expansion of medical technology has made the hospital a place for the application of rapid and sophisticated methods of medical management to the acutely ill. Priorities are efficiency, cost effectiveness, and fast turnover of patients. Though lengths of stay have been reduced, admission rates have risen. ' In inner city areas hospitals have become sources of primary care for their catchment populations, thereby usurping the role of the general practitioner.2 It is against this background that home care has developed.
Trend analysis of annual and seasonal rainfall time series in the Mediterranean area

Precipitation trend analysis, on different spatial and temporal scales, has been of great concern during the past century because of the attention given to global climate change by the scientific community. According to some recent studies, the Italian territory has been suffering a precipitation decrease, especially in the last 50 years, and the southern areas seem to be more affected. The aim of the present study is to analyse rainfall time series over a wide time interval and a wide area, detecting potential trends and assessing their significance. For this purpose, 211 gauged stations, mainly located within the Campania region, southern Italy, have been analysed for the period 1918–1999. An accurate database has been set up through a data quality and time series homogeneity process. Statistical analysis of the database highlight that (1) the trend appears predominantly negative, both at the annual and seasonal scale, except for the summer period when it appears to be positive; (2) over the whole reference period, positive and negative trends are significant respectively for 9 and 27% of total stations and (3) over the last 30 years, a negative trend is instead significant for 97% of the total stations.

A Core Algorithm for Object Tracking and Monitoring via Distributed Wireless Sensor Networks

We consider object tracking and monitoring implemented via the use of distributed wireless sensor networks. We view the signal processing and communications operations performed in such networks, in conjunction with the time constraints imposed on their signal processing objectives and the limited life-spans of their sensors. We identify some of the object identification and network monitoring functions that are embedded in such systems. We subsequently focus on a core algorithm whose various manifestations may serve effectively a variety of network functions, and propose its novel application for image and sound object tracking. We also propose a new distributed version of the algorithm for the monitoring of data rates in the network.
Incorporating Stream Features into Groundwater Contouring Tools Within GIS

Hydrogeologists often are called upon to estimate surfaces from discrete, sparse data points. This estimation is often accomplished by manually drawing contours on maps using interpolation methods between points of known value while accounting for features known to influence the water table's surface. By contrast, geographic information systems (GIS) are good at creating smooth continuous surfaces from limited data points and allowing the user to represent the resulting surface resulting with contours, but these automated methods often fail to meet the expectations of many hydrogeologists because they do not include knowledge of other influences on the water table. In this study, we seek to fill this gap in the GIS‐based methodology for hydrogeologists through an interactive tool that shapes an interpolated surface based on additional knowledge of the water table inferred from gaining or losing streams. The modified surface is reflected in water table contours that, for example, “V” upstream for gaining streams, and can be interactively adjusted to fit the user's expectations. By modifying not only the contours but also the associated interpolated surface, additional contours will follow the same trend, and the modified surface can be used for other analyses like calculating average gradients and flow paths. The tool leverages Esri's ArcGIS Desktop software, building upon a robust suite of mapping tools. We see this as a prototype for other tools that could be developed for hydrogeologists to account for variations in the water table inferred from local topographic trends, pumping or injection wells, and other hydrogeologic features.
Facilitating Secure Sharing of Personal Health Data in the Cloud

Background Internet-based applications are providing new ways of promoting health and reducing the cost of care. Although data can be kept encrypted in servers, the user does not have the ability to decide whom the data are shared with. Technically this is linked to the problem of who owns the data encryption keys required to decrypt the data. Currently, cloud service providers, rather than users, have full rights to the key. In practical terms this makes the users lose full control over their data. Trust and uptake of these applications can be increased by allowing patients to feel in control of their data, generally stored in cloud-based services. Objective This paper addresses this security challenge by providing the user a way of controlling encryption keys independently of the cloud service provider. We provide a secure and usable system that enables a patient to share health information with doctors and specialists. Methods We contribute a secure protocol for patients to share their data with doctors and others on the cloud while keeping complete ownership. We developed a simple, stereotypical health application and carried out security tests, performance tests, and usability tests with both students and doctors (N=15). Results We developed the health application as an app for Android mobile phones. We carried out the usability tests on potential participants and medical professionals. Of 20 participants, 14 (70%) either agreed or strongly agreed that they felt safer using our system. Using mixed methods, we show that participants agreed that privacy and security of health data are important and that our system addresses these issues. Conclusions We presented a security protocol that enables patients to securely share their eHealth data with doctors and nurses and developed a secure and usable system that enables patients to share mental health information with doctors.
