A Human Error Analysis of Commercial Aviation Accidents Using the Human Factors Analysis and Classification System (HFACS)

The Human Factors Analysis and Classification System (HFACS) is a general framework originally developed and tested within the U.S. military as a tool for investigating and analyzing the human causes of aviation accidents. Based upon Reason's (1990) model of latent and active failures HFACS addresses human error at all levels of the system, including the condition of aircrew and organizational factors. The purpose of the present study was to assess the utility of the HFACS framework as an error analysis and classification tool outside the military. Specifically, HFACS was applied to commercial aviation accident records maintained by the National Transportation Safety Board (NTSB). Using accidents that occurred between January 1990 and December 1996, it was demonstrated that HFACS reliably accommodated all human causal factors associated with the commercial accidents examined. In addition, the classification of data using HFACS highlighted several critical safety issues in need of intervention research. These results demonstrate that the HFACS framework can be a viable tool for use within the civil aviation arena.
PSLP: Padded SLP automatic vectorization

The need to increase performance and power efficiency in modern processors has led to a wide adoption of SIMD vector units. All major vendors support vector instructions and the trend is pushing them to become wider and more powerful. However, writing code that makes efficient use of these units is hard and leads to platform-specific implementations. Compiler-based automatic vectorization is one solution for this problem. In particular the Superword-Level Parallelism (SLP) vectorization algorithm is the primary way to automatically generate vector code starting from straight-line scalar code. SLP is implemented in all major compilers, including GCC and LLVM. SLP relies on finding sequences of isomorphic instructions to pack together into vectors. However, this hinders the applicability of the algorithm as isomorphic code sequences are not common in practice. In this work we propose a solution to overcome this limitation. We introduce Padded SLP (PSLP), a novel vectorization algorithm that can vectorize code containing non-isomorphic instruction sequences. It injects a near-minimal number of redundant instructions into the code to transform non-isomorphic sequences into isomorphic ones. The padded instruction sequence can then be successfully vectorized. Our experiments show that PSLP improves vectorization coverage across a number of kernels and full benchmarks, decreasing execution time by up to 63%.
A dynamic drawing algorithm for interactive painterly rendering

We present a new approach to create painterly renderings of an animated 3D scene, allowing a controllable trade-off between scene fidelity and stylistic design. Our approach extends and complements existing systems in order to ensure temporal coherence while maintaining consistent stroke density, and allowing a wide variety of stroke styles. It is based on a new dynamic painting algorithm which selects a suitable set of sample stroke locations based on an object-space hierarchy. Strokes are created at these locations, with attributes assigned using arbitrary stylistic choices: examples include scene-derived decisions such as having stroke orientation follow curvature or silhouette directions, or user-supplied constraints such as global orientation or thickness. Stroke rendering is then performed using appropriately filtered information from a set of G-buffers. We describe an improved stroke rendering technique which allows a faithful depiction of the scene while letting the user specify his prefered stroke style. All rendering is interactive and performed on the GPU.
The link between apolipoprotein E, presenilin 1, and kinesin light chain 1 gene polymorphisms and age-related cortical cataracts in the Chinese population

Purpose To study whether presenilin 1 (PSEN1), apolipoprotein E (APOE), and kinesin light chain 1 (KLC1) genotypes are associated with the risk of developing age-related cortical cataracts in the Han Chinese population. Methods We collected and analyzed the blood samples of 227 cortical cataract patients and 263 controls. Genotyping was performed by direct sequencing after PCR amplification, and allele frequencies were tested for the Hardy–Weinberg equilibrium. Results The G allele and GG genotype of KLC1 rs8702 were significantly over-represented among cataract patients, as compared to healthy controls (allele P[χ2]=0.001 and genotype P[χ2]=0.008, respectively) and are associated with an odds ratio for cataract development of 1.54 (95% confidence interval of 1.19–2.01). More specifically, carrying the rs8702 C allele was associated with a decreased cortical cataract risk among individuals devoid of the APOE4 allele (OR=0.55; P[χ2]=0.003), whereas it has no significant effect among APOE4 carriers (OR=0.57; P[χ2]=0.36). Conclusions The KLC1 and APOE genes may be novel susceptibility genes for age-related cataracts.

Il Liceo Scientifico Statale Marconi, CTS-NTD di Milano, ha progettato tali attivita, attribuendo al concetto di inclusione un ambito piu esteso, con l’obiettivo di portare l’abitudine all’uso delle ICT dentro la prassi didattica quotidiana.
Factorization with Erroneous Data

Factorization algorithms for recovering structure and motion from an image stream have many advantages, but traditionally requires a set of well tracked feature points. This limits the usability since, correctly tracked feature points are not available in general. There is thus a need to make factorization algorithms deal successfully with incorrectly tracked feature points. We propose a new computationally efficient algorithm for applying an arbitrary error function in the factorization scheme, and thereby enable the use of robust statistical techniques and arbitrary noise models for individual feature points. These techniques and models effectively deal with feature point noise as well as feature mismatch and missing features. Furthermore, the algorithm includes a new method for Euclidean reconstruction that experimentally shows a significant improvement in convergence of the factorization algorithms. The proposed algorithm has been implemented in the Christy–Horaud factorization scheme and the results clearly illustrate a considerable increase in error tolerance.
Autodétermination et création du « chez-soi » : un nouvel enjeu pour les technologies de soutien aux personnes en situation de handicap

La situation de handicap ne constitue plus aujourd’hui une entrave aux choix et a la realisation de la personne. En effet, les technologies de soutien aux personnes en situation de handicap sont dorenavant en mesure de proposer des solutions. Cette vision particuliere de la mobilisation technologique peut favoriser l’expression de la liberte fondamentale de choix et de prise en main consciente de son existence, en d’autres mots, d’etre autodeterminee. Ce principe, qui concerne le fait de decider de son destin ou de sa vie sans influence externe indue, trouve toute sa dimension dans le maintien en milieu residentiel. La mise en perspective de la notion d’autodetermination, dans le cadre des dynamiques de spatialisation propres au logement des personnes en situation de handicap, permet l’emergence d’un cercle vertueux. Les technologies de soutien a l’autodetermination sont, en effet, un moyen pour la personne d’apprehender son espace et inversement, cet espace personnel reconnu comme tel permet a son tour l’autodetermination.
The importance of temporal scale when mapping landscape change in permafrost environments using Interferometric Synthetic Aperture Radar

The properties of satellite interferometric synthetic aperture radar (InSAR) data were assessed to determine whether it is suitable to detect small landscape changes in a permafrost environment. The advantage of InSAR is that it can generate measurements with large spatial coverage with relatively fine horizontal and vertical resolution. Amplitude, coherence, and interferometric phase images were generated from SAR data from the ERS1/2, RADARSAT-1, and JERS-1 satellites. It was found that the variations between repeat pass period and technical characteristics of the satellites resulted in each system producing unique data sets. Decorrelation between images generally resulted in coherence that was too low to map the absolute rate and direction of surface motion. However, the relative decrease in coherence is useful for establishing the relative rates of ground surface change and linking these to geomorphic and hydrologic processes.

The Effects of Varying Volumes of Crystalloid Administration Before Cesarean Delivery on Maternal Hemodynamics and Colloid Osmotic Pressure

The value of intravenous crystalloid administration in preventing spinal-induced hypotension in the parturient has recently been questioned. Also, the association between increasing crystalloid volume and decreasing postpartum colloid osmotic pressure (COP) raises concern regarding the risk of maternal and fetal pulmonary edema. To study the dose-response effect of varying amounts of crystalloid volume prior to spinal anesthesia, we measured maternal hemodynamic variables and maternal and fetal COP in three groups of healthy parturients receiving spinal anesthesia for elective cesarean delivery. Fifty-five parturients were randomized in a double-blind fashion to receive one of 10, 20, or 30 mL/kg of crystalloid volumes prior to induction of spinal anesthesia. Measurements included mean arterial blood pressure (MAP), cardiac index (CI), and systemic vascular resistance index (SVRI) recorded using noninvasive thoracic impedance monitoring until delivery. Maternal and neonatal COP were measured. All groups showed declines in MAP and SVRI from baseline at 5 min after spinal anesthesia, but the amount of decline did not differ among groups. Total ephedrine and additional intravenous (IV) fluid administered did not differ among groups. The 20- and 30- mL/kg groups showed a larger decline in maternal COP than the 10-mL/kg group; no differences in neonatal COP were seen with varying preload. We conclude that increasing the amount of IV crystalloid administered to 30 mL/kg in the healthy parturient does not significantly alter maternal hemodynamics or ephedrine requirements after spinal anesthesia and has no apparent benefit.

Dealing with Query Contention Issue in Real-Time Data Warehouses by Dynamic Multi-level Caches

The issue of query contention and scalability is the most difficult issue facing organizations deploying real-time data warehouse solutions. The contention between complex selects and continuous inserts tends to severely limit the scalability of the data warehouses. In this paper, we present a new method called dynamic multi-level caches, to effectively deal with the problem of query contention and scalability in real-time data warehouses. We differentiate between queries with various data freshness requirements, and use multi-level caches to satisfy these different requirements. Every query arriving at the system will be automatically redirected to the corresponding cache to access the required data, which means that the query loads are distributed to multi-level caches instead of becoming blocked in the only one cache due to the contention between query and update operations. Extensive experiments on several real datasets show that our method can effectively balance the query loads among multi-level caches and achieve desirable system performance.
Strategy and leadership

Purpose – The long‐time preoccupation with leadership as the key concept in organisational change ought to be replaced by a more general view that it is the quality of strategic thinking that leads to appropriate change within organisations.Design/methodology/approach – As an example of how strategic thinking works, the current demographic changes in longevity are explored and opportunities for drawing on the experience of older people in business are suggested.Findings – Strategic thinking depends on a collective view of organisational membership and takes for granted that leadership is a collective function not an individual one.Originality/value – Explores a neglected area of strategic concern – namely demographic change and its implications for organizations.
Studying the perception of color components' relative amounts in blended colors

Visualization provides the means for a natural information interpretation with low cognitive loads. In such context, color is a powerful way to convey information properties. One use of color in visualization is color blending, in which distinct colors represent different data properties and one data item which verifies more than one property is represented in a color that consists of blending its properties' colors. Humans are able to perceive the original components that generate particular colors. However, the amount of each color component may not be evident, possibly making it difficult for users to quantify the relative relevance of the each property. We have performed a user-study to verify to which extent people can perceive relative amounts of color components in blended colors. Results of our study have provided a set of guidelines to follow when using color blending for in information visualization.
Extended lactation in dairy cows: effects of milking frequency, calving season and nutrition on lactation persistency and milk quality

Twelve spring-calving and twelve winter-calving cows were managed for extended lactation cycles of 18-months duration, with the former group then completing a second extended lactation. Half of the cows were fed according to standard management practice for the herd; the other half received supplementary concentrate from week 9 of lactation onwards. Commencing at the same time, half of the udder of each cow was subjected to increased milking frequency (thrice daily rather than twice daily). Lactation persistency (and hence total milk yield) was significantly increased by frequent milking. Winter calving cows and supplemented cows also exhibited better persistency, but this was only evident up until the point of re-breeding, at around lactation week 33. Milk composition was measured in the spring-calving cows in both their first and second extended lactations. Composition altered during the course of the lactation, protein and fat percentages increasing and lactose percentage decreasing, irrespective of treatment. The quality of the milk for processing into cheese, fermented products, heat-treated products and cream liqueurs was assessed by calculation of casein number (casein protein as a proportion of total protein). Processing quality declined across the course of lactation in those groups that showed poor persistency but not in those that maintained a persistent lactation. Milk hygienic quality (somatic cell counts) showed parallel changes. Body condition score increased during the course of lactation but was not affected by supplementation; none of the cows became excessively fat. All cows remained healthy throughout the extended lactations and the majority (33/36) re-bred successfully. By demonstrating that lactation persistency is plastic and can be improved by simple management interventions, the results lend support to the economic arguments in favour of extended lactation cycles. The likely welfare benefits of extended lactation are also discussed.
Complex language encounters: Observations from linguistically diverse South African classrooms

This article reports on the initial observation phase of a larger, longitudinal project that explores complex language encounters in grades R (Reception) to 3 classrooms in South Africa. Complex language encounters refer to teacher-learner exchanges that take place when neither teachers nor learners are first language speakers of the language of instruction, in this case English. Observations during teaching practice visits to linguistically and culturally diverse South African urban classrooms yielded several vignettes that illustrate the need for teachers to be provided with strategies to lessen the confusion of some language encounters. Although preliminary, our findings underline how critical it is for teachers to possess full proficiency in the language of instruction as well as cross-cultural competence. That is, in order to attend adequately to diverse learners’ sense-making efforts, teachers need to know how to relate to learners by ‘border crossing’ linguistically, culturally and conceptually.
Psychological Interventions for Post-traumatic Stress Symptoms in Psychosis: A Systematic Review of Outcomes

Individuals with severe mental health problems, such as psychosis, are consistently shown to have experienced high levels of past traumatic events. They are also at an increased risk of further traumatisation through victimization events such as crime and assault. The experience of psychosis itself and psychiatric hospitalization have also been recognized to be sufficiently traumatic to lead to the development of post-traumatic stress (PTS) symptoms. Rates of post-traumatic stress disorder (PTSD) are elevated in people with psychosis compared to the general population. The current guidance for the treatment of PTSD is informed by an evidence base predominately limited to populations without co-morbid psychiatric disorders. The systematic review therefore sought to present the current available literature on the use of psychological treatments targeting PTS symptoms in a population with a primary diagnosis of a psychotic disorder. The review aimed to investigate the effect of these interventions on PTS symptoms and also the effect on secondary domains such as psychotic symptoms, affect and functioning. Fifteen studies were identified reporting on cognitive behavior therapy, prolonged exposure, eye movement desensitisation and reprocessing and written emotional disclosure. The review provides preliminary support for the safe use of trauma-focused psychological interventions in groups of people with severe mental health problems. Overall, the interventions were found to be effective in reducing PTS symptoms. Results were mixed with regard to secondary effects on additional domains. Further research including studies employing sufficiently powered methodologically rigorous designs is indicated.
Mission specification and control for unmanned aerial and ground vehicles for indoor target discovery and tracking

This paper describes ongoing research by Georgia Tech into the challenges of tasking and controlling heterogonous teams of unmanned vehicles in mixed indoor/outdoor reconnaissance scenarios. We outline the tools and techniques necessary for an operator to specify, execute, and monitor such missions. The mission specification framework used for the purposes of intelligence gathering during mission execution are first demonstrated in simulations involving a team of a single autonomous rotorcraft and three ground-based robotic platforms. Preliminary results including robotic hardware in the loop are also provided.
Epinephrine Infusion in Man: Standardization, Normal Response, and Abnormal Response in Idiopathic Hypertrophic Subaortic Stenosis

A standard test was designed for measurement of the effect of epinephrine infusion on systolic time intervals in 14 normal subjects as a dose-response phenomenon. In order that we might examine the sensitivity of the test, it was applied in nine patients with idiopathic hypertrophic subaortic stenosis.Normal subjects had a characteristic response—a progressive shortening of the duration of electromechanical systole, left ventricular ejection time, and pre-ejection period. Their left ventricular ejection time, corrected for heart rate, did not change. Patients with idiopathic hypertrophic subaortic stenosis responded to epinephrine infusion with paradoxical lengthening of their left ventricular ejection time, corrected for heart rate. After beta blockade (with propranolol), reinfusion of epinephrine shortened the left ventricular ejection time, corrected for heart rate, to normal levels.
LA RELACIÓN 2D:4D MUESTRA UNA LEVE CORRELACIÓN POSITIVA CON LA DOMINANCIA AGRESIVA, PERO NO CON LA DOMINANCIA SOCIAL, EN JUGADORES DE FÚTBOL DE CATEGORÍAS FORMATIVAS DE UN EQUIPO DE PRIMERA DIVISIÓN EN URUGUAY

Existe considerable evidencia que apoya la existencia de una diferencia en los niveles de agresividad entre hombres y mujeres. Se ha propuesto además que los niveles de testosterona (T) estarían relacionados con las conductas agresivas. En este estudio se explora la eventual correlación entre dos formas de dominancia -la dominancia social y la dominancia agresiva- y una medida indirecta de los niveles de T fetal, la relación 2D:4D, en un grupo de jugadores de fútbol de las categorías formativas de un equipo de Primera División del Uruguay. Los resultados obtenidos muestran una leve correlación positiva de la relación 2D:4D y la dominancia agresiva, pero no con la dominancia social. En este trabajo se discuten los resultados a la luz de observaciones dispares observadas en otras poblaciones y se presentan algunas propiedades psicométricas de las escalas de dominancia social y agresiva empleadas.
Analysis on Volatiles of Temperature-Pressure Forming Materials by Cotton Stalk

The volatiles materials is the first killer to damage the lives of indoor air pollutions. Based on the single-factor method, volatiles of temperature-pressure forming materials by cotton stalk was studied by Py-GC/MS to control indoor air pollutions. Therefore, Py-GC/MS was used to analyze the components from pyrolysis products of temperature-pressure forming materials by cotton stalk,. After treated with freeze-drying, the comminuted power of temperature-pressure forming materials by cotton stalk was pyrolyzed in He atmosphere at 450�� , then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization. The main and abundant constituents were arbon dioxide, ethene, ethoxy-, 1,6-anhydro-. beta. -D-glucopyranose, phenol, 2-methoxy-4-(1-propenyl)-, cedrol, thylene oxide, butanal, ethanone, 1-phenyl-, oxime, and so on. More than 30 compounds were identified in the pyrolysis products of Cotton stalk by the Py-GC/MS analysis. Most of the pyrolysis products could be used as biomedicine. But some of the volatiles of temperature-pressure forming materials by cotton stalk was toxic. And this meant that cotton stalk need be pretreatment.
