The last decade has produced an explosion in neuroscience research examining young children's early processing of language that has implications for education. Noninvasive, safe functional brain measurements have now been proven feasible for use with children starting at birth. In the arena of language, the neural signatures of learning can be documented at a remarkably early point in development, and these early measures predict performance in children's language and pre-reading abilities in the second, third, and fifth year of life, a finding with theoretical and educational import. There is evidence that children's early mastery of language requires learning in a social context, and this finding also has important implications for education. Evidence relating socioeconomic status (SES) ...

Adolescents with emotional and behavioral disorders (EBD) often fail to master literacy skills, in part because disruptive behaviors interfere with task engagement and persistence. The theory of behavioral momentum explains the persistence of behavior in the face of changing environmental conditions. The current exploratory study examined variables related to behavioral momentum in the context of a continuous reading task. Participants were three adolescents identified with EBD who were instructional on fifth-grade material. Results indicated that when participants read a third-grade paragraph immediately before a fifth-grade paragraph, they decreased the latency to initiate reading of the fifth-grade paragraph and increased words read correctly per minute on the first 10 words of the fifth-grade paragraph. Results are discussed in terms of the theory of behavioral momentum and the nature of interventions that may be developed to increase ...

Special education researchers have made noteworthy progress toward conceptualizing literacy research questions, designing quality studies, and disseminating the results of their research. These advancements have been made through the establishment and refinement of quality research indicators. Unfortunately, this progress has mostly eluded the arena of juvenile justice special education research. The purpose of this article is to review juvenile justice literacy studies and provide juvenile justice personnel and researchers with methodological and practical considerations for improving the quality of juvenile justice literacy research. The focus is on advancing group designs. Practical concerns are based on the first-year experiences of researchers who implemented an Institute of Education Sciences Goal 3 study with the aim of determining the efficacy of literacy instructional programs in a juvenile ...

All African Nations belong to the category of third world underdeveloped countries of the world. UNDP Human Development Index uses factors like per capita income, health of the people, and educational attainment to classify countries. Adult literacy and gross enrolment ratios are indicators of education status. This paper uses Nigeria, a typical African country, to illustrate the problems posed by adult illiteracy to national development. Statistical data are used to show the low levels of adult literacy with disparities between males and females; urban and rural areas, and between different zones of Nigeria and the continent. Enrolments and completion rate in adult literacy programmes are presented. Nigeria's policy on adult and non formal education as reflected in the Nigerian constitution (1999), National Policy on Education (2004 edition), Decree 17 on the National Commission for Mass Literacy, ...

There is a clear incentive, therefore, for early consideration of the measures required to meet noise and vibration standards. The platform or rig owner and the operator are jointly responsible for agreeing a noise and vibration control policy and approach at the conceptual design stage, and for then passing on their requirements to the engineering design teams. The engineering design teams and acoustic and vibration specialists for their part need to use all their skill and judgement to apply that policy to the intensely complex job of designing and fabricating topsides facilities. With these concerns as background, UEG started, and has nearly completed, a two-phase study to provide detailed guidance to project managers and designers to assist them to develop appropriate policy and procedures and to help them put those procedures into practice. This paper describes the development of UEG's study, its application and benefits.

Drawing upon the cultural risk perspective and writings on risk taking, this paper seeks to develop ideas relating to the effective use of school cyberspace. It is argued that some individuals respond to exaggerated, yet seductive, discourses of online risks by over-blocking, unreasonably restricting students' Internet activity. At the same time, there are sensible, even compelling, motivations for teachers as well as students to use the school Internet to engage in low-level risk taking, fostering excitement, identity construction and networked media literacy. Connecting these seductive pushes and pulls of risk it is ultimately maintained that the fostering of trust through open communication is key in overcoming over-blocking whilst allowing for greater educational gains, realised in part through certain types of low-level risk taking in school cyberspace.

The ability to use an acoustic stethoscope to detect lung and/or heart sounds, and then to then communicate one's interpretation of those sounds is an essential skill for many medical professionals. Interpretation of lung and heart sounds, in the context of history and other examination findings, often aids the differential diagnosis. Bedside assessment of changing auscultation findings may also guide treatment. Learning lung and heart auscultation skills typically involves listening to pre-recorded normal and adventitious sounds, often followed by laboratory instruction to guide stethoscope placement, and finally correlating the sounds with the associated pathophysiology and pathology. Recently, medical simulation has become an important tool for teaching prior to clinical practice, and for evaluating bedside auscultation skills. When simulating cardiovascular or pulmonary problems, high-quality lung and heart sounds ...

A seasonal forecasting technique to produce probabilistic and deterministic streamflow forecasts for 23 basins in Norway and northern Sweden is developed in this work. Large scale circulation and moisture fields, forecasted by the ECHAM4.5 model 4 months in advance, are used to forecast spring flows. The technique includes model output statistics (MOS) based on a non-linear Neural Network (NN) approach. Results show that streamflow forecasts from Global Circulation Model (GCM) predictions, for the Scandinavia region are viable and highest skill values were found for basins located in south-western Norway. The physical interpretation of the forecasting skill is that stations close to the Norwegian coast are directly exposed to prevailing winds from the Atlantic ocean, which constitute the principal source of predictive information from the atmosphere on the seasonal timescale.

Orientation in the environment can draw on a variety of cognitive strategies. We asked 634 healthy volunteers to perform a comprehensive battery administered through an internet website (www.gettinglost.ca), testing different orientation strategies in virtual environments to determine the effect of age and gender upon these skills. Older participants (46-67years of age) performed worse than younger participants (18-30 or 31-45years of age) in all orientation skills assessed, including landmark recognition, integration of body-centered information, forming association between landmarks and body turns, and the formation and use of a cognitive map. Among all tests, however, the ability to form cognitive maps resulted to be the significant factor best at predicting the individuals' age group. ...

According to Schumpeter, the creative process of economic development can be divided into the stages of invention, innovation (commercialization) and imitation. Each stage is associated with specific skills. This paper examines whether Schumpeter?s assertion was correct, i.e. whether the invention and innovation stages should be undertaken by different agents. In addition, we examine whether there is a rationale for the Schumpeterian entrepreneur to include the inventor in the commercialization process. Combining the abilities of the entrepreneur and the inventor may serve to facilitate customer adaptation, strengthen knowledge transfers and reduce uncertainty, thereby expanding market opportunities.

Common forms of testing of student understanding of science content can be misleading about their understanding of the nature of scientific thinking. Observational astronomy integrated with related ideas of force and motion is a rich context to explore the correlation between student content knowledge and student understanding of the scientific thinking about that content. In this paper, we describe this correlation in detail with a focus on a question about the relative motion of the Sun and the Earth. We find that high achieving high school students throughout New York City struggle with what constitutes scientific justification and thought processes, but can improve these skills tremendously in an inquiry-oriented summer astronomy-physics program.

There has been growing international consensus on issues related to child labour - evident in various declarations, platforms, conventions, programmes of action etc. Child labour is the economic exploitation of children, or performance of any work that is likely to be hazardous or to interfere with the child's health or physical, mental, spiritual, moral or social development. Poverty is the principal cause of child labour. Mostly the children work to support their families and also for their own survival. Paradoxically, however, child labour further aggravates the poverty syndrome as it usually deprives the children of education and opportunity to acquire skills for developing earning potentials. Other causes of child labour include family indebtedness, the lack or poor quality of schooli...

We propose an approach to achieving early recognition of gesture patterns. Early recognition is a method for recognizing sequential patterns at their earliest stage. Therefore, in the case of gesture recognition, we can get a recognition result for human gestures before the gestures are finished. The most difficult problem in early recognition is knowing when the system has determined the result. Most traditional approaches suffer from this problem, since gestures are often ambiguous. At the start of a gesture, in particular, it is very difficult to determinate the recognition result since insufficient input data have been observed. Therefore, we have improved on the traditional approach by using a self-organizing map.

Context: The Balanced Budget Act (BBA) of 1997 allowed some rural hospitals meeting certain requirements to convert to Critical Access Hospitals (CAHs) and changed their Medicare reimbursement from prospective to cost-based. Some subsequent CAH-related laws reduced restrictions and increased payments, and the number of CAHs grew rapidly. Purpose: To examine factors related to hospitals' decisions to convert and time to CAH conversion. Methods: Eighty-nine rural hospitals in Iowa were characterized and observed from 1998 to 2005. Cox proportional hazards models were used to identify the determinants of time to CAH conversion. Findings: T-test and one-covariate Cox regression indicated that, in 1998, Iowa rural hospitals with more staffed beds, discharges, and acute inpatient days, higher operating margin, lower skilled swing bed days relative to acute days, and located in relatively high density counties were more likely to convert later or not convert before 2006. ...

Recent nucleosynthesis calculations of Type II supernovae using advanced neutrino transport determine that the early neutrino winds are proton-rich. However, a fraction of the ejecta emitted at the same time is composed of neutron-rich pockets. In this paper we calculate the nucleosynthesis contribution from the neutron-rich pockets in the hot convective bubbles of a core-collapse supernova and show that they do not contribute significantly to the total nucleosynthesis.

Elution profiles of total lipoproteins, apolipoprotein B (apoB) concentrations in lipoproteins, and plasma triglyceride (TG) levels were examined in early-, late-, and non-lactating cows. Additionally, arteriovenous (A-V) differences were also measured to elucidate the uptake of TG and apoB-containing lipoproteins in mammary gland. Non-lactating cows showed three major peaks corresponding to triglyceride-rich lipoprotein (TRL), low density lipoprotein (LDL), and high density lipoprotein (HDL) fraction, whereas both early- and late-lactating cows revealed two peaks corresponding to TRL and HDL. The peak area of TRL in early- and late-lactating cows were significantly (p < 0.05) smaller than that in non-lactating cows. The plasma TG levels and apoB-48 concentrations of TRL in early- and late-lactating cows were also significantly (p < 0.01) lower. Furthermore, early lactating ...

The paper investigates early Soviet policies regarding the institution of waqf (charitable endowment) in Turkestan, questioning the issue of the post-colonial character of the early Soviet administration. After taking into consideration practices related to waqf management in modern Muslim states and European colonial empires, the paper briefly describes the tsarist administrative approach to the issue. We then address the ambiguity inherent in Soviet policies on waqf requisition and restitution during Civil War years. In the section that follows we deal with different groups of Muslim intellectuals that attempted to use the Soviet state in their mutual struggle over authority in Central Asian society and describe the creation and functioning of the bureaucracies responsible for managing w...

Six patients with diskitis following lumbar disk surgery were investigated by Computed Tomography (CT). Four patients underwent CT in a rather early phase of the disease (5-37 days after the onset of the symptoms): a posterior paravertebral fluid collection was always recognized, while the plain film was normal. Later on (2-4 months), the classical signs of diskitis were evident, with both CT and the plain film. The collection was always present at CT. A reintervention, performed on 3 patients, revealed the purulent content of the collections. It seems reasonable to suggest a relationship between the collection and the subsequent diskitis; the collection is probably an early sign of the disease. Its detection is of grat value, because it could allow an immediate and adequate therapy. The authors stress the usefulness of performing CT in an early phase on this kind of symptomatic patients.

The early diagnosis of such disorders is of major importance because, in most cases, severe consequences can only be averted by early treatment. The value of magnetic resonance imaging (MRI) in many orthopaedic and traumatological conditions is generally accepted. The value of MRI in this particular field is illustrated by typical case reports on common clinical problems [Deutsch] Der Fruehdiagnose von Erkrankungen des Kindes- und Jugendalters kommt grosse Bedeutung zu, da oftmals nur durch eine daraus resultierende Fruehbehandlung schwerwiegende Folgen vermieden werden koennen.

Necrotizing enterocolitis (NEC) is the most common severe gastrointestinal emergency that affects premature newborns. This disease often has a rapid onset with few, if any, antecedent signs that can be used to reliably predict its occurrence. Its rapid onset and progression to death, as well as its severe morbidity when the infant survives, begs for early diagnostic tools that may be used in determining those infants who would be at greatest risk for development of the disease and for whom early preventative measures could be targeted. Although studies have suggested efficacy of several techniques such as breath hydrogen, inflammatory mediators in blood, urine or stool, and genetic markers, these all have drawbacks limiting their use. The application of newly developed "omic" approaches may provide biomarkers for early diagnosis and targeted prevention of this disease. PMID:19190533

There are very few examples of audio-based computerized tests, but for many disciplines, such as foreign language and music, there appear to be many benefits to this type of testing. The purpose of the present study was to develop and compare computer-delivered and audiocassette/paper-and-pencil versions of a listening test. The test was a measure of progress achievement of academic listening comprehension and vocabulary for high-intermediate level students of English as a Second Language (ESL) at a university-affiliated institute. The underlying assumption investigated was that the use of computer and audio technology for classroom progress tests would provide benefits of convenience and improved sound quality while providing measurement quality and validity that were at least comparable to the paper form of such tests. Results with 28 students indicate that the computerized test performed at least as well as the paper-and-pencil version, with generally comparable validity. ...

The running data of the super energy saving car on a course with a little difference within 1m in elevation were reported which was developed to pursue the minimum fuel consumption. The super car was featured by length of 2.72m, vehicle running mass of 38.5kg, engine displacement of 42cc and a rear drive tricycle with 2(F) and 1(R). The super car turned 10 times on a racing circuit of 925m a round at 20km/h or more in average speed, repeating engine-driven running and engine-stopped coasting. As a result, the vehicle velocity distribution was slightly affected by tire revolution, while the accelerating resistance was strongly affected by that. With an increase in tire revolution, the maximum accelerating resistance decreased in driven running and its variation converged rapidly in coasting. A total of distance in driven running was only 8% of the whole running one because of probably skilled driving as well as the vehicle performance. The fuel consumption rate also ...

Pattern and model makers are skilled tradespersons who may be exposed to hardwoods, softwoods, phenol-formaldehyde resin-impregnated woods, epoxy and polyester/styrene resin systems, and welding and metal-casting fumes. The relationship of respiratory symptoms (wheezing, chronic bronchitis, dyspnea) and pulmonary function (FVC% predicted, FEV1% predicted, FEV1/FVC% predicted) with interview-derived cumulative exposure estimates to specific workplace agents and to all work with wood, plastic, or metal products was investigated in 751 pattern and model makers in southeast Michigan. In stratified analyses and age- and smoking-adjusted linear and logistic regression models, measures of cumulative wood exposures were associated with decrements in pulmonary function and dyspnea, but not with other symptoms. In similar analyses, measures of cumulative plastic exposures were associated with wheezing, chronic bronchitis, and dyspnea, but not with decrements in pulmonary ...

In October last year the first intercomparison of measurements of the soil radon concentrations between various laboratories in Slovakia was realised. The organisation of this intercomparison was conducted by the Slovak Legal Metrology in Banska Bystrica together with the Slovak National Accreditation Service in Bratislava (SNAS). The scientific guarantee of the exercise was the State metrological Centre for radon quantities, which is working at the Research base of Slovak Medical University in Bratislava. The main objective of the intercomparison was to verify the correctness of the methods for the soil radon measurements of the authorised laboratories for radon volume activities in soil air. The intercomparison (signed as SLM ILC 3/03) was performed as a 'circular' metrology comparison, in accordance with a methodical directive MSA 0117-98, published by SNAS. Six laboratories were participating on the intercomparison and there have been two stages of the work one in the radon chamber ...

The relevance of the teacher to the success of any education innovation is not open to contention. Equally incontentious is the relevance of education and training to the success of the teacher in the attainment of his/her professional goals. It is against this background that this paper examines the continuing education imperatives in the present basic education crusade in Nigeria. Here continuing education is conceptualized as a process for developing teacher's skill for coping with changing demands of the job through regular exposure to professional renewal programmes. The paper contends that inasmuch as the teacher will continue to play a pivotal role in the execution of educational innovations, then further education and training as it affects him/her must receive priority attention in the conceptualization and implementation of such innovations. To this end, the paper advocates: teacher exchange programmes between Nigeria and other countries of the world; ...

Following the Hungerford Massacre the British Government imposed additional strict firearms legislation in 1988 that involved several classes of arms being placed into the prohibited category. By way of compensation a scheme was introduced to allow the unrestricted possession and transfer of the newly prohibited arms, other firearms and "prohibited weapons", if de-activated to a standard acceptable to the Secretary of State. Approved standards for firearm de-activation were drawn up in 1989. The inspection of the de-activated arms was devolved to the two Gun Barrel Proof Houses at London and Birmingham, as otherwise the task of inspecting the thousands of guns involved would have overloaded the firearms section at the Huntingdon Forensic Science Service Laboratory, who were already dealing with criminal firearms cases submitted by 41 of the 43 police forces throughout England and Wales, as well as providing technical assistance to the Home Office and Government Ministers.

The aim of this study was to investigate the early histological changes of tumors and inflammatory cells after BNCT in the rat brain. Rats were treated with BNCT using boronophenylalanine (BPA) 7 days after implantation of C6 glioma cells. The tumors were assessed with magnetic resonance imaging and histopathological examination at 4 days after BNCT. The mean tumor volumes were 39#+-#2 mm"3 in the BNCT group and 134#+-#18 mm"3 in the control group. In the BNCT group, tumor cells showed a less pleomorphic appearance with atypical nuclei and mitotic figures. The Ki-67 labeling index was 6.5%#+-#4.7% in the BNCT and 35%#+-#3.8% in the control group. The reactions of the inflammatory cells were examined with ED-1 as macrophage marker and OX42 as microglia marker. ...

The nature of the first generation of stars in the Universe remains largely unknown. Observations imply the existence of massive primordial stars early in the history of the universe, and the standard theory for the growth of cosmic structure predicts that structures grow hierarchically through gravitational instability. We have developed an ab initio computer simulation of the formation of primordial stars that follows the relevant atomic and molecular processes in a primordial gas in an expanding universe. The results show that primeval density fluctuations left over from the Big Bang can drive the formation of a tiny protostar with a mass of just one percent that of the sun. The protostar is a seed for the subsequent formation of a massive primordial star.

This article reviews antisocial personality disorder, psychopathy, and violence and develops a three factor model of personality traits. Then a discussion of related personality disorders precedes the development of a categorical two factor model of impulsive versus remorseless violence. A paradigm of proactive, medical, and school based early intervention and prevention is advocated as a useful addition to the reactive detention of criminal justice. Integration of psychological tests, neuroimaging, and genomic data in early childhood and school based intervention strategies to prevent the development of conduct disorder and attenuate criminal propensity inform this approach.

A high voltage self-blowing circuit breaker with closing resistors is equipped with an auxiliary contact inserted in the trip control circuit of an electrical circuit breaker. The auxiliary contact is actuated by the mechanical control rod of the circuit breaker in such a way as to prevent any operator closing error. A high-speed mechanism is inserted in the link system connecting the control rod and the auxiliary contact, with dead travel to delay closing of the auxiliary contact when a closing operation takes place and to prevent a tripping order from being transmitted too early. Such an early transmission would be liable to cause a flashover on the inserter contacts and damage to the circuit breaker.

The usefulness of helical CT early phase images optimized by the SmartPrep method for evaluation of wall invasion by colorectal cancer was investigated. Between August 1997 and September 1998, CT was performed to evaluate the primary tumor and local extension in 10 consecutive patients with colorectal cancer confirmed by barium enema- and/or colonoscopy. Early-phase images were acquired by using SmartPrep application software. This method allows the optimal scan delay time to be obtained by continuous monitoring of increases in CT values after injection of contrast medium. Sections of the surgical specimens, close to the same plane as the CT images, and of the same slice thickness, were analyzed histopathologically. All 10 cancers, regardless of size, showed strong enhancement on the early-phase images (81.4-112 HU, mean: 95.1 HU). The strongly enhanced image areas on CT corresponded to the primary cancer areas on ...

We derive stellar masses, ages, and star formation histories (SFHs) of massive early-type galaxies in the z = 1.237 RDCS1252.9-2927 cluster and compare them with those measured in a similarly mass-selected sample of field contemporaries drawn from the Great Observatories Origin Deep Survey South Field. Robust estimates of these parameters are obtained by comparing a large grid of composite stellar population models with 8-9 band photometry in the rest-frame near-ultraviolet, optical, and IR, thus sampling the entire relevant domain of emission of the different stellar populations. Additionally, we present new, deep U-band photometry of both fields, giving access to the critical far-ultraviolet rest frame, in order to empirically constrain the dependence of the most recent star formation processes on the environment. We also analyze the morphological properties of both samples to examine the dependence of their scaling relations on their mass and environment. We ...

Based on the view that major changes in the social and economic context in the United States require major policy changes related to early childhood education, this paper examines the factors supporting public policy changes and how advocates for change in early childhood education might incorporate effective strategies. The paper is presented in two parts. Part 1 reviews the research on state policy settings and the factors that tend to support policy change. This part focuses attention on the ways that state policymakers appear to learn from what is going on elsewhere and incorporate new ideas into their policy agendas. Several strategic implications for advocates of policy change are presented, such as brainstorming a list of potential obstacles to the introduction of a policy innovation or shaping the debate so the public will support change. Part 2 of the paper takes these general strategic implications and considers their relevance to ...

Reproductive parameters were monitored in 50 post-partum Bos indicus x Bos taurus animals located on four farms in two ecological zones of Panama. Progesterone (P_4) concentrations were measured in four of these animals twice a week and their reproductive organs palpated per rectum once a week until 60 days post-artificial-insemination or post-natural-service. The other 46 cows were palpated for early pregnancy between days 45 and 60 post-service. The mean P_4 concentration in cows with palpable corpora lutea (CL) was 10.3#+-#4.0 nmol/L; when no Cl were detected, the mean P_4 level was 2.2#+-#1.6 nmol/L. Of the 46 animals palpated for early pregnancy, 36 (70%) were found to be pregnant, one (2%) exhibited early embryonic death and one (2%) aborted; the other eight cows (17%) were anoestrous. The mean P_4 concentration in pregnant cows was 11.9#+-#4.0 nmol/L and the calving to conception interval was 148 days. (author). 13 ...

We present the results of an isophotal shape analysis of three samples of galaxies in the Coma cluster. Quantitative morphology, together with structural and photometric parameters, is given for each galaxy. Special emphasis has been placed on the detailed classification of early-type galaxies. The three samples are: i) a sample of 97 early-type galaxies brighter than m_B = 17.00 falling within one degree from the center of the Coma cluster; these galaxies were observed with CCD cameras, mostly in good to excellent resolution conditions; ii) a magnitude complete sample of 107 galaxies of all morphological types down to m_B = 17.00 falling in a circular region of 50 arcmin diameter, slightly offcentered to the North-West of the cluster center; the images for this and the next sample come from digitized photographic plates; iii) a complete comparison sample of 26 galaxies of all morphological types down to m_R = 16.05 (or m_B \\simeq 17.5), also ...

ObjectivesThe main objective of this study is to address the following specific questions: 1. Are the delayed effects of poor early diet on whole organism performance and senescence contingent on, or exacerbated by, the subsequent occurrence of compensatory growth? 2. Does the rate of growth influence levels of resting metabolism and/or oxidative stress, and if so, for how long does this persist? 3. How are the levels of early nutrition, growth, resting metabolism and oxidative stress linked to the lev [continued...]DescriptionIt is now widely appreciated that, while animals may appear to recover from periods of poor food quality or quantity experienced in early development, adverse effects may occur later in adult life. Such effects can influence the performance of complete cohorts of animals, and have important consequences for population dynamics. The reasons why such delayed effects occur across the animals' lifetimes ...

In the present political climate, politicians are singling out children's programs and services for budget cuts. The need for teacher education programs to prepare early childhood teachers as children's advocates is becoming ever more evident. For years, the National Association for the Education of Young Children has called for greater involvement of early childhood educators as advocates for programs and services that promote children's health and education. In teacher education programs, however, this call has largely gone unheeded. The purpose of this article is to discuss the importance of involving teacher candidates in advocacy activities and policy research, the obstacles that teacher educators can face when incorporating advocacy components into their teacher education courses and programs, and resources and strategies they can use. This discussion builds upon a motivation-obstacles-resources framework developed for adoption of ...

Abstract It is now widely accepted that remembering the past and imagining the future rely on a number of shared processes and recruit a similar set of brain regions. However, memory and future thinking place different demands on a range of processes. For instance, although remembering should lead to early associative retrieval of event details, event construction may be slower for future events, for which details from different memories are combined. In order to shed light on the question of how the brain distinguishes between memories and future thoughts, we investigated the differences in the electrophysiological correlates of the vivid elaboration of future and past events. In the slow cortical potentials of 24 healthy human participants, differences during early elaboration were obser...

We report Sr, Pd and Ag abundances for a sample of metal-poor field giants and analyze a larger sample of Y, Zr, and Ba abundances. The [Y/Zr] and [Pd/Ag] abundance ratios are similar to those measured for the r-process-rich stars CS 22892-052 and CS 31082-001. The [Pd/Ag] ratio is larger than predicted from the solar-system r-process abundances. The constant[Y/Zr] and [Sr/Y] values in the field stars places strong limits on the contributions of the weak s-process and the main s-process to the light neutron-capture elements. Stars in the globular cluster M 15 possess lower [Y/Zr] values than the field stars. There is a large dispersion in [Y/Ba]. Because the r-process is responsible for the production of the heavy elements in the early Galaxy, these dispersions require varying light-to-heavy ratios in r-process yields.

In spite of the improved imaging techniques currently available, mortality for pancreatic cancer is still high, and pancreatics is often diagnosed only in its advanced stages. The authors investigated the value of different imaging techniques - i.e., US, CT, and ERCP - for an early diagnosis, when a more effective (curative?) treatment can be suggested. Fifty-six cases of pancreatic cancer and 36 cases of chronic pancreatitis were evaluated. The results indicate that ERCP, with the help of statistical methods, is superior to US and CT not only in evaluating early neoplastic or inflammatory lesions, but also for their differential diagnosis. In the letter case, ERCP can sometimes be used as a valid alternative to fine-needle aspiration biopsy.

Recently, we cloned purpurin cDNA as an upregulated gene in the axotomized fish retina. The retina-specific protein was secreted from photoreceptors to ganglion cell layer during an early stage of optic nerve regeneration in zebrafish retina. The purpurin worked as a trigger molecule for axonal regrowth in adult injured fish retina. During zebrafish development, purpurin mRNA first appeared in ventral retina at 2 days post-fertilization (dpf) and spread out to the outer nuclear layer at 3 dpf. Here, we investigated the role of purpurin for zebrafish retinal development using morpholino gene knockdown technique. Injection of purpurin morpholino into the 1-2 cell stage of embryos significantly inhibited the transcriptional and translational expression of purpurin at 3 dpf. In the purpurin mo...

To test the hypothesis that leaf level photosynthetic related traits might confer late successionals a competitive advantage over early successionals in low light growth conditions, steady photosynthetic assimilation and dynamic photosynthetic induction related traits were examined in low light grown seedlings with contrasting successional status. Compared with the early successionals, late successionals as a group significantly exhibited lower leaf gas exchange rates. While late successionals required a longer time to respond to simulated sunflecks, they had lower rates of induction losses after sunflecks. Such photosynthetic induction traits allowed late successionals to more effectively utilize subsequent sunflecks. It was observed that plants with lower gas exchange rates responded mor...

We identify a source coincident with SN 2009kr in Hubble Space Telescope pre-explosion images. The object appears to be a single point source with an intrinsic color V - I = 1.1 #+-# 0.25 and M_V = -7.6 #+-# 0.6. If this is a single star, it would be a yellow supergiant of log L/L _s_u_n #approx# 5.1 and a mass of 15"+"5 _-_4 M _s_u_n. The spatial resolution does not allow us yet to definitively determine if the progenitor object is a single star, a binary system, or a compact cluster. We show that the early light curve is similar to a Type IIL SN, but the prominent H#alpha# P-Cygni profiles and the signature of the end of a recombination phase are reminiscent of a Type IIP. The evolution of the expanding ejecta will play an important role in understanding the progenitor object.

The authors determined migration timing and abundance of juvenile spring chinook salmon Oncorhynchus tshawytscha and juvenile steelhead/rainbow trout O. mykiss from three populations in the Grande Ronde River basin. Based on migration timing and abundance, two distinct life-history strategies of juvenile spring chinook and O.mykiss could be distinguished. An early migrant group left upper rearing areas from July through January with a peak in the fall. A late migrant group descended from upper rearing areas from February through June with a peak in the spring.

The aim of this review is to evaluate the role of inflammatory spine disease in patients with chronic back pain. The contribution of imaging modalities for the diagnostic evaluation of back pain is discussed. A systematic literature search based on the classification of seronegative spondyloarthropathies and rheumatoid arthritis was performed. The results of this search and the experiences in a large collective of rheumatological patients are analyzed. The prevalence of rheumatoid arthritis (1-2%) is comparable to that of spondyloarthropathies (1.9%). The etiology of these entities is not fully elucidated. Magnetic resonance imaging is increasingly used for early detection and surveillance of therapy with TNF-#alpha# antagonists. Bone marrow edema, which is only detectable with MRI, represents an early sign of inflammation. Therapy with TNF-#alpha# antagonists is based on clinical and laboratory criteria, and signs of inflammation in MRI. MRI ...

Sheltering, evacuation and distribution of stable iodine tablets are considered to be major early emergency actions aiming at diminishing the consequences after a release of radioactive materials from nuclear power plants into the air. Whether in real situations emergency managers will act accordingly is hard to predict. Uncertainties associated with these decisions are termed 'volitional' uncertainties. These uncertainties, however, cannot be assessed by expert judgements as they express the decision at stake in an emergency situation. Uncertainties on the times to implement countermeasures and on the times for the general population to respond to these measures can be assessed by experts, as they represent 'lack-of-knowledge' uncertainties. This paper describes the difference in approach of both types of uncertainties and shows the results of expert judgements on the latter type of uncertainties in early ...

Two cases of focal nodular hyperplasia (FNH), in which ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MR) studies detected an atypical hemorrhagic pattern associated with an intrahepatic arterio venous malformation (AVM) around the growths, are presented. In both cases, histology demonstrated a very early regenerative stage and necrotic-hemorrhagic areas within the lesions. In these cases, the analysis of radiological findings, surgical specimens and histology seemed to confirm the pathogenetic hypothesis suggested by Wanless: in normal liver parenchyma, a ``blood steal`` phenomenon due to congenital or acquired intrahepatic AVM could cause ischemic damage, appearing as a hemorrhagic necrotic area, the extent of which depends on the degree of residual portal supply.

The European sea bass Dicentrarchus labrax is a marine teleost important in Mediterranean aquaculture. The development of the entire digestive tract of D. labrax, including the pharynx, was investigated from early embryonic development to day 5 post hatching (dph), when the mouth opens. The digestive tract is initialized at stage 12 somites independently from two distinct infoldings of the endodermal sheet. In the pharyngeal region, the anterior infolding forms the pharynx and the first gill slits at stage 25 somites. The other three gill arches and slits are formed between 1 and 5 dph. Posteriorly, in the gut tube region, a posterior infolding forms the foregut, midgut and hindgut. The anus opens before hatching, at stage 28 somites. Associated organs (liver, pancreas and gall bladder) ar...

It was recognized from the early days of commissioning of Bruce B that Control Maintenance staff would require a level of expertise to be able to maintain Special Safety Systems in proper running order. In the early 80's this was achieved through hands on experience during the original commissioning, troubleshooting and placing of the various systems in service. Control maintenance procedures were developed and implemented as the new systems came available for commissioning, as were operating manuals,training manuals etc. Under the development of the Maintenance Manager, a Conduct of Maintenance section was organized. One of the responsibilities of this section was to develop a series of Maintenance Administrative Procedures (MAPs) that set the standards for maintenance activities including training.

The early Miocene Pedregoso Formation is one of the numerous formations rich in organic matter within the stratigraphic record of the Urumaco Trough, in the central area of the Falcon Basin. Due to its lithological characteristics and stratigraphic position, this formation is of great interest regarding the basin's petroliferous systems. The evaluation of various inorganic and organic geochemical parameters indicates that the organic matter is primarily of marine origin, deposited in a marine carbonate environment typical of reefal systems, under oxic-to-dysoxic conditions. The low variability in the TOC concentrations and in the distributions of the biomarkers extracted from the samples suggests that the paleoenvironmental conditions and the organic-matter supply remained approximately co...

For early-stage firms, successful commercialization of each new product is critically important, given the shortage of financial resources, the limited product portfolio, and small staffs typical of such firms. This paper investigates two key contributing factors for new product success in entrepreneurial firms: designing products that are appealing to target users in both form and function and designing products that can be manufactured at an attractive margin so that the new enterprise can generate much needed positive cash flow. These two practices-industrial design and cost engineering-are well studied in the context of larger, established corporations but have not been explored in the context of new ventures. This study focuses on the intensity of individual and combined adoption of d...

On March 31, 1995, the US Department of Energy filed a draft application for certification of compliance with the US Environmental Protection Agency (USEPA) to show the Waste Isolation Pilot Plant's compliance with the USEPA's environmental standards, making the application the first of its kind. Demonstration of compliance is by performance assessment. This paper is an early review of the performance assessment in the draft application, by the Environmental Evaluation Group, an oversight group. The performance assessment in the draft application is incomplete. Not all relevant scenarios have been analyzed. The calculation of potential consequences often does not use experimental data but rather estimates by workers developing additional data. The final compliance application, scheduled for October 1996 needs to consider additional scenarios, and be fully based on experimental data.

Plants release secondary metabolites into the soil that change the chemical environment around them. Exogenous abscisic acid (ABA) is an important allelochemical whose role in successional trajectories has not been examined. We hypothesized that ABA can accumulate in the soil through successional processes and have an influence on forest dynamics. To this end, we investigated the distribution of ABA in forest communities from early to late successional stages and the response of dominant species to the gradient of ABA concentrations in three types of forests from northern to southern China. Concentrations of ABA in the soils of three forest types increased from early to late successional stages. Pioneer species? litters had the lowest ABA content, and their seed germination and seedling ea...

Hepatocellular carcinoma (HCC) represents a major health problem as it afflicts an increasing number of patients worldwide. Albeit most of the risk factors for HCC are known, this is a deadly syndrome with a life expectancy at the time of diagnosis of less than 1?year. Definition of the molecular principles governing the neoplastic transformation of the liver is an urgent need to facilitate the clinical management of patients, based on innovative methods to detect the disease in its early stages and on more efficient therapies. In the present study, we have combined the analysis of a murine model and human samples of HCC to identify genes differentially expressed early in the process of hepatocarcinogenesis, using a microarray-based approach. Expression of 190 genes was impaired in murine ...

Problems and solutions in the diagnosis and operative treatment were clarified by retrospective evaluation of cases of intramedullary tumor in which MRI and surgery had been performed. The subjects were 16 patients (21-75 years old, mean age: 45 years) whose tumor was surgically removed between 1991 and 1998. MRI was performed preoperatively, and T1-weighted images, T2-weighted images, and enhanced images were obtained. Angiography was also performed in some cases. The histological diagnosis based on the MRI findings before surgery were compared with the pathological diagnosis after the operation. In 9/16 cases (56%), the preoperative histological diagnosis based on the MR images was the same as the pathological diagnosis after the operation. In 8 of the 11 cases (73%) whose images showed clear tumor margins and well shaped the tumor, the tumors were completely removed. The concordance rate between the pathological diagnosis during and after the operation was 67%. Spinal cord ...

BACKGROUND: The urgent need for patient safety education for healthcare students has been recognised by many accreditation bodies, but to date there has been sporadic attention to undergraduate/graduate medical programmes. Medical students themselves have identified quality and safety of care as an important area of instruction; as future doctors and healthcare leaders, they must be prepared to practise safe healthcare. Medical education has yet to fully embrace patient safety concepts and principles into existing medical curricula. Universities are continuing to produce graduate doctors lacking in the patient safety knowledge, skills and behaviours thought necessary to deliver safe care. A significant challenge is that patient safety is still a relatively new concept and area of study; thus, many medical educators are unfamiliar with the literature and unsure how to integrate patient safety learning into existing curriculum. DESIGN: To address this gap and provide ...

This study, part of OECD/CERI's project on Measuring the Social Outcomes of Learning, investigates the relationship between educational attainment and political participation in Austria. First, a model based on various theoretical considerations is introduced. This incorporates direct educational effects as well as indirect effects that occur through material resources, social capital, civic orientations and values. Using a multivariate analytical approach the model is applied to the 2002 European Social Survey. Three forms of political participation are distinguished, namely voting, elite-directed and elite-challenging activities. Educational attainment is found to have significant effects on all three types but the strongest impact is on elite-challenging activities. The latter includes forms of political action such as signing petitions and buying or boycotting certain products which are increasingly accepted as a legitimate way to express one's political preferences. Most of the ...

Decadal-scale climate variations over the Pacific Ocean and its surroundings are strongly related to the so-called Pacific decadal oscillation (PDO) which is coherent with wintertime climate over North America and Asian monsoon, and have important impacts on marine ecosystems and fisheries. In a near-term climate prediction covering the period up to 2030, we require knowledge of the future state of internal variations in the climate system such as the PDO as well as the global warming signal. We perform sets of ensemble hindcast and forecast experiments using a coupled atmosphere-ocean climate model to examine the predictability of internal variations on decadal timescales, in addition to the response to external forcing due to changes in concentrations of greenhouse gases and aerosols, volcanic activity, and solar cycle variations. Our results highlight that an initialization of the upper-ocean state using historical observations is effective for successful hindcasts of the PDO and ...

Purpose: The purpose of this research was to identify the extent and scope of changes to radiography practice. Method: Questionnaires were sent to radiology managers at acute National Health Service (NHS) hospitals in 2000 as a follow-up to an initial survey conducted in 1998. Information was sought on region, teaching/non-teaching status, the nature of extended role tasks undertaken and the year in which these tasks were first undertaken. Results: Some 172 questionnaires were returned from a total of 253 dispatched (68%). In 161 hospitals radiographers administered intravenous injections and performed barium enemas in 119 hospitals, while a red-dot system was in operation in 141 hospitals. Reporting by radiographers had increased since 1998. Replies indicated that, at 124 hospitals, radiographers were reporting in ultrasound. Skeletal reporting was the second most-frequently-reported activity, with 63 hospitals indicating that radiographers reported in this modality, while barium ...

Groups are assigned or formed to perform tasks that one person cannot accomplish alone. This lesson describes the classification of work groups, group unity, leadership, motivation, recognition, conflict resolution, and remediation associated with managing groups and their activities. Advantages associated with group process include 1) the generation of better ideas, 2) ability to assume greater risks; make fewer errors; 3) the capacity for greater knowledge and 4) information, and for some problems, production of better decisions. Groups may be formal or informal. Formal groups may be organic, task-directed, or committees. Informal groups arise when it becomes obvious that a group will work better or may be formed by a discipline within the organization or through friendships. The size of the group its status within the organization, the goals established, and the dependence of the members on the group all may affect the cohesiveness of the group. Leadership of the group must keep the ...

Topics concerning the problems associated with older and aging dams are considered including: what can be done to extent the lifetime of an old dam, the decision to decommission a dam based on a value judgment that the risk of maintaining the dam is too great for society's acceptance, the possibility of change in the level of risk tolerance with time in a technological environment, traditional surveillance methods used by dam owners in the Y2K situation, and the unreality of dam immortality. Trends and means for preserving older dams for their owner's purposes are outlined, as well as their lifetime compared to that of the downstream systems they serve. Despite the fact that we live in a throwaway society, dam owners cannot just leave their dam asset when they are through with using it. Someone has to maintain the dam, or ensure that it is safely decommissioned when the owner is finished with it. On a worldwide scale the available pool of experienced dam engineers is ...

The authors investigated the role of Computerized Tomography in guiding fine needle biopsy (FNB) in small (2 2 cm in diameter for CT-guided FNB sensitivity, specificity and diagnostic accuracy. Cytologic specimens were positive for malignancy in 40/52 cases (76.9%) and negative in 12 (23.1%). Clinical-surgical follow-up confirmed all the positive cytologic findings (40 cases), while 2 of the extant 12 cases were false negatives (95.20% sensitivity, 100% specificity and 96.15% diagnostic accuracy). 158 of 195 nodules > 2 cm in diameter and with clinical surgical follow-up (81.3%) were positive for malignancy and 34 were negative (17.43%) (98.75% sensitivity, 97.14% specificity and 98.46% diagnostic accuracy). Pneumothorax occurred in 33 patients (16.5%) with nodules > 2 cm in diameter as a complication of biopsy. Hemoptysis occurred in 15 patients (7.5%). In the whole group of lung lesions, the complications were pneumothorax in 80 patients (4.1%), hemoptysis in 199 (10.4%) and ...

This article is a case study of an Internet chat room outreach project in Perth, Western Australia. The CyberReach project sought to adapt current peer based health promotion outreach, training and supervision frameworks to an online outreach setting in a way that was effective and supported by the online community. It targeted marginalised groups to trial the provision of online mental and sexual health promotion incorporating a participatory action research model into its development and implementation. Three 6-week trial periods were conducted and significant changes were made in response to changes in the online environment and to improve sustainability and effectiveness of the protocols. Four themes arose from CyberReach's experience: online group processes are unique due to the creation of extensive personal networks and occurrence of disclosure without face-to-face contact across potentially large geographic barriers; flexibility is required to adapt to technological changes and ...
