Visibly learning: teachers’ assessment practices for students with high and very high needs

This paper examines the assessment practices of teachers working with students with special educational needs in New Zealand primary and secondary regular and special schools. A national survey was used to identify current assessment practices used by teachers working with students designated, through a resourcing policy, as having high and very high needs. Specifically, the survey sought to determine the type of assessment practices used, reasons for using different approaches, the role of the person carrying out the assessment and levels of confidence in assessing students in relation to learning. The use of learning stories as a form of narrative assessment was further explored through the questionnaires and in a relatively small number of interviews. The results showed that teachers were largely responsible for assessment, and that the three main assessment methods used included collecting examples of work, observations and anecdotal records. Teachers reported confidence in assessing students for learning, but not for funding applications and assistive technology applications. Approaches such as narrative assessment and learning stories were used by some teachers in school‐based settings. Learning stories and narrative assessment are strategies where parents, teachers, teacher‐aides and students engage in meaningful dialogue around learning. Teachers reported that through narrative assessment they could demonstrate that learners with high and very high needs were visibly learning. Through a sociocultural conceptualisation of formative assessment, the role of teachers and learners in assessment is explored.
Peer Evaluation Behavior of First Year Engineering (FYE) students and K-12 students

A student’s ability to work in a team setting is vital to their college career as well as their work life and therefore it is often a significant factor in a corporate hiring process. Recognizing this need, a number of U.S. undergraduate programs as well as many K-12 instructors, particularly the ones in Project Lead The Way (PLTW) courses use team or project based courses in their curricula. Hundred’s of these programs, including K-12, also use a teamwork formation and assessment system, CATME (Comprehensive Assessment of Team Member Effectiveness), that asks students to assess the teamwork behavior of their peers. Much work has been done in the use of teams in K-12 but not on the analysis of teamwork behavior and the effective use of teams. The goal of our research was to determine whether or not K-12 students behave similarly to First Year Engineering (FYE) students, in particular, when they rate their peers as well as when they are being rated is the quality of peer evaluations performed by K-12 students similar to the quality of peer evaluations performed by First Year Engineering (FYE) students?
Relational Incentive Contracts with Persistent Private Information

This paper investigates relational incentive contracts with continuous, privately observed agent types that are persistent over time. With fixed agent types, full separation is not possible when continuation equilibrium payoffs following revelation are on the Pareto frontier of attainable payoffs. This result is related to the ratchet effect in that: (1) a type imitating a less productive type receives an information rent, and (2) with full separation, one imitating a more productive type receives the same future payoff as that more productive type. However, the reason for (2) is fundamentally different than with the ratchet effect. It arises from the dynamic enforcement requirement in relational contracts, not from the principal having all the bargaining power, and applies whatever the distribution between principal and agent of the future gains from the relationship (i.e., whatever the point on the Pareto frontier). This result extends to sufficiently persistent types under certain conditions.
Outbreak detection based on a tree-structured anatomic model for infection

When designing an outbreak detection system, it may be preferable to use existing medical data as input instead of requesting additional date from medical professionals. In this paper we propose using existing symptom data and reported immunological reactions in EPRs in combination with a model based on the anatomy of disease. We argue that these data for all patients in a geographical area are sufficient to indicate the increase in incidence of infectious diseases. We transform lexical patient data in a seven-step algorithm to a twodimensional space representing the medical anomalies in a geographical area.

Person Identification using Skeleton Information from Kinect

In recent past the need for ubiquitous people identification has increased with the proliferation of human- robot interaction systems. In this paper we propose a methodology of recognizing persons from skeleton data using Kinect. First a half gait cycle is detected automatically and then features are calculated on every gait cycle. As part of new features, proposed in this paper, two are related to area of upper and lower body parts and twelve related to the distances between the upper body centroid and the centriods derived from different joints of upper limbs and lower limbs. Feature selection and classification is performed with connectionist system using Adaptive Neural Network (ANN). The recognition accuracy of the individual people using the proposed method is compared with the earlier methods proposed by Arian et. al and Pries et. al. Experimental results indicate that the proposed approach of simultaneous feature selection and classification is having better recognition accuracy compared to the earlier reported ones.
Immunotoxicological Evaluation of Environmental Chemicals Utilizing Mouse Lymphocyte Mitogenesis Test

To establish a useful and convenient bioassay for evaluating immunotoxicological effects of environmental chemicals, lymphocyte mitogenesis tests of about 255 chemicals and environmental water were performed. We determined the growth-inhibitory effect of the environmental chemicals on the mouse splenic lymphocyte mitogenesis using lipopolysaccharide and concanavalin A as the specific mitogen for B cells and T cells, and evaluated toxicity on humoral immunity and cell-mediated immunity, respectively. The DNA content of grown cells was determined by the novel ethidium bromide-fluorophotometry method, with 96-well microplates. Of the 255 chemicals tested, 173 chemicals showed inhibitory effects on the mitogenesis. The data were classified into four typical inhibition patterns from the dose-response curves. The chemicals were categorized into six groups in the respect of inhibition selectivity between B cell mitogenesis and T cell mitogenesis. Some chemicals, such as metallic compounds, showed nonspecific effects for B cell and T cell-mitogenesis, which was attributed to the cytotoxicity. The previous reports relating to immunotoxicity found about 123 chemicals; 78 chemicals (63.4%) were positive and one chemical (0.8%) was negative for both experimental results and reported results. In total, the concordance between experimental results and reported results is 64.2%. In the application of river water concentrates for the lymphocyte mitogenesis test, some of the samples inhibited both B cell and T cell mitogenesis at the tested volume of 7.2 ml. These results indicated that the lymphocyte mitogenesis test is applicable in estimating immunotoxicity of pollutants in environmental water as well as authentic environmental chemicals.
Do Golden Parachutes Increase CEO's DESIRE to Be Taken Over? Empirical Evidence from Australia and United States

This study investigates whether the large payouts that are available to Chief Executive Officers (CEOs) from a change in corporate control (takeover) do motivate some CEOs to seek acquisition of their firms by making them more attractive to a takeover bid. Using Australian and the US data, employing OLS regression, we report that there is a significant relationship between a CEOs change in control payments and their firm’s net cash levels (one of the key factors of takeover attractiveness). Our empirical results also indicate that CEOs desire their firms to be acquired by decreasing shareholders’ equity, thus supporting the view that change in control payments exist primarily for incumbent managers. Our findings provide support to the proposition that managers enjoy having large cash balances to be available to them as it allows them with greater opportunities to derive personal benefit from
An Efficient Reused VLSI Architecture of FMO/Manchester Encoding using SOLS Technique for DSRC Applications

: the dedicated short-extend correspondence (DSRC) is an effective procedure to push the clever transportation framework into our day by day life. The DSRC guidelines for the most part receive FM0 and Manchester codes to achieve dc-adjust, upgrading the flag unwavering quality. By and by, the coding-differing qualities between the FM0 and Manchester codes truly constrain the possibility to outline a proficient reused VLSI engineering for both. In this paper, the comparability arranged rationale disentanglement (SOLS) system is proposed to defeat this impediment. The encoding capacity of this paper can completely bolster the DSRC benchmarks of America, Europe, and Japan. This paper builds up a proficient reused VLSI design, as well as displays an effective execution contrasted and the current works. The proposed engineering of this paper investigation the rationale size, region and power utilization utilizing Xilinx 14.2
9. CLAY CONDUCTION AND PORE STRUCTURE OF OCEANIC BASALTS FROM DSDP/ODP HOLE 504B1

The resistivity, porosity, and cation exchange capacity of 36 basaltic samples recovered in Hole 504B during four DSDP and ODP legs have been measured in the laboratory at room temperature and atmospheric pressure. The pres­ ence of chlorites and particularly smectites as alteration products of basalt phases is reflected by high values of cation exchange capacity (CEC). Whereas the massive units of Layers 2A and 2B are defined by high and uniform CEC values, the more fractured and altered pillows are characterized in the entire hole by even higher values of CEC and a large vari­ ability. The lowest CEC values, measured for the massive units of Layer 2C, are due to changes of basalt alteration fa­ des with depth and the related decreasing abundance of smectites with increasing depth in the oceanic crust. The porosity and the apparent formation factor (computed from resistivity measurements made with a fluid salinity similar to that of seawater) are related by an inverse power law similar to Archie's formula, with m close to 1.0 and a as large as 9.1. A review of the literature shows that such a low m value equates to current conduction in cracks and microcracks present throughout the rock. The presence of these microstructures reflects the extensional regime under which the rock formed at the ridge axis, and they were conserved by precipitation of clay minerals attributable to intense hy­ drothermal circulation. The comparison of these results to similar studies of mid-ocean ridge basalt physical properties indicates that m tends to increase to values close to 2.0 with age. Such values are, in fact, similar to those found for sedi­ mentary rocks and probably reflect an increased tortuosity of the conducting pore space with increasing age. An inverse relationship also relates CEC and apparent formation factor, indicating that surface conduction of clay minerals plays an important role during downhole electrical experiments. This provides a plausible key to the paradox of low permea­ bility and high apparent porosity obtained from comparing the in-situ experiments conducted in Hole 504B.
East Antarctic sea ice in spring: spectral albedo of snow, nilas, frost flowers and slush, and light-absorbing impurities in snow

Abstract Spectral albedos of open water, nilas, nilas with frost flowers, slush, and first-year ice with both thin and thick snow cover were measured in the East Antarctic sea-ice zone during the Sea Ice Physics and Ecosystems eXperiment II (SIPEX II) from September to November 2012, near 65°S, 120°E. Albedo was measured across the ultraviolet (UV), visible and near-infrared (nIR) wavelengths, augmenting a dataset from prior Antarctic expeditions with spectral coverage extended to longer wavelengths, and with measurement of slush and frost flowers, which had not been encountered on the prior expeditions. At visible and UV wavelengths, the albedo depends on the thickness of snow or ice; in the nIR the albedo is determined by the specific surface area. The growth of frost flowers causes the nilas albedo to increase by 0.2–0.3 in the UV and visible wavelengths. The spectral albedos are integrated over wavelength to obtain broadband albedos for wavelength bands commonly used in climate models. The albedo spectrum for deep snow on first-year sea ice shows no evidence of light-absorbing particulate impurities (LAI), such as black carbon (BC) or organics, which is consistent with the extremely small quantities of LAI found by filtering snow meltwater. Estimated BC mixing ratios were in the range 0.1–0.5 ng of carbon per gram of snow.
Electrochemical method for Ag-PEG nanoparticles synthesis

In this work we present an electrochemical method to successfully prepare silver nanoparticles using only polyethylene glycol as stabilizer and without any other reactive. Here we study the use of the polymeric stabilizer to allow the introduction of a potential tool to reinforce the control of the size and shape of the nanoparticles throughout the synthesis process. The evolution of the reactions was followed by UV-Vis spectroscopy. The electrode processes were characterized by cyclic voltammetric measurements and the final product was studied by Atomic Force Microscopy, Transmission Electron Microscopy, and X-Ray Diffraction. The influences of the current density, polymer length, and concentration media were analyzed.

Biological Sequence Alignment for Bioinformatics Applications Using MATLAB

Biological Sequence alignment is widely used operation in the field of Bioinformatics and computational biology as it is used to determine the similarity between the biological sequences. The two basic alignment algorithms i.e. Smith Waterman for local alignment and Needleman Wunsch for global alignment have been used in this paper. The algorithms have been developed and simulated using MATLAB for genome analysis and sequence alignment. The local and global alignment has been presented and the results are shown in the form of Dot plots and local and global scores for the sequences. The proposed work is a useful tool that can aid in the exploration, interpretation and visualization of data in the field of molecular biology.
Temporal adaptation to light intensity for spatially complex stimuli

The human eye is a complex organ of the human body which is able to cope with a lot of different situations. One of these situations is adapting to different light intensities by changing the dynamic range of the eye, so-called temporal adaptation. This report gives insight into what temporal adaptation means for luminance visibility while driving on an urban street during nighttime. The first step needed was collecting data of luminance values falling onto the retina while driving in the dark. As driving with a head-mounted eye-tracker was impractical and insufficiently accurate, the experimental set-up was changed into a lab set-up. An HD camera was used to record a video during driving in the dark, while a luminance camera was used to measure the corresponding luminance values. The resulting video was shown to 20 participants in the lab, and they were asked to watch the movie as if they were driving themselves. Their gaze positions on the screen were measured using a table mounted eye tracker. The gaze positions were converted into saliency maps, which were then combined with the luminance values of the video frames to generate weighted luminance maps. From the weighted luminance maps luminance profiles were deduced, representing the luminance value falling on the center of the retina as a function of time. The luminance values measured in these profiles varied between about 1 and 18,000 cd/m2. About 54% of the fluctuations in luminance within a one-second time frame had a difference below 1000 cd/m2, while about 6% of the fluctuations had a difference larger than 10,000 cd/m2. The effect of temporal adaptation on these luminance fluctuations was estimated by superimposing a temporal adaptation model existing in literature on the luminance profiles. Light adaptation (i.e. from a dark to a bright environment) is so fast that we considered it instantaneous for our application. Dark adaptation (i.e. from a bright to a dark environment) is somewhat slower and so was expected to delay the perception of the lower luminance values. However, also for dark adaptation the initial drop in perceived luminance is so fast that temporal adaptation only had a small effect on perceived luminance for the highest light intensity fluctuations. It should be noted, however, that literature on temporal adaptation only reports adaptation to homogeneous light intensity fields, while in our particular case of driving on an urban street during nighttime the visual field was characterized by a rapidly changing spatially complex light intensity field. Models to describe temporal adaptation to spatially complex light fields do not exist yet, and so, may affect the conclusions of our research.
Translocation of Evechinus chloroticus in the SUR 5 Fishery and the reproductive potential of large urchins

Evechinus chloroticus (commonly known as Kina) is a commercially important species found in coastal New Zealand waters. Their gonad quality is, however, poor in many regions and thus the areas with high quality gonads tend to be overfished. Feeding E. chloroticus on enhanced food diets is a common method to improve the roe quality but limited success has been achieved in improving the gonad quality to acceptable market standards. Translocation of E. chloroticus in the wild as a method for commercial gonad enhancement is examined in this thesis within the South Coast urchin fishing area (SUR5) to assess if gonad quality could be improved. Approximately 1000kgs of urchins were translocated from an area with poor quality gonad and high urchin population densities (Passage Island) to an area of high gonad quality and low urchin population densities (Sealers Bay) in Chalky Inlet a commercially fished area. The urchins were left for five months and sampled three times within this period. Changes in gonad index (GI) were measured to assess whether translocating E. chloroticus can be effective. Significant differences occurred after the translocations with increased gonad growth in both the translocated samples compared to the Passage Island samples which had lower gonad indices. There were also differences in gonad index over the five month study length as a result of spawning before the last sample was taken, which resulted in significant changes in gonad index. Aristotle’s lantern index increased in two translocated samples over the five month period. Evechinus chloroticus fished from the Southern Coast SUR5 fishing area are of a large test diameter (TD) >120mm. Questions have been raised about the reproductive potential of these large urchins, thus the opportunity was taken to test
Measurement strategy of PRISMA: design and realisation

To approach the aims of the German research project PRISMA, a n integrated measurement strategy was developed, following the nesting principle: (i) drift experiments which involved sampling in a defined water mass aiming at the analyses of transfer and transformation processes were supplemented by (i i) analyses at 3 equidistant drifting positions 3 n.m. (nautical miles) apart, which we]-e performed in (iii) a grid of equidistant stations at f~xed positions 10 n.m. apart, covering the German Bight, to identify hydrodynamic and biogeochem~cal changes or interferences affecting the dnft area. In this way, the spatial representativeness of frequent point measurements at drifting stations could be estimated, as well as the short-term variability during the 4 d duration of each grid survey in the German Bight. The latter also provided data sets for transport modelling. In addition time series data were collected at 6 mooring stations equipped with current meters, CTD and transmission meters. Some of the modelling was already performed during the experiment with a daily operational model (used by BSH, Bundesamt fiir Seeschiffahrt und Hydrographie, Hamburg) comprising atmospheric and ocean models. The output provided nearly real-time informatjon on the drift direction of the defined water masses. The results of more extensive model calculations allowed the subsequent description of water mass transports in different depths of the German Bight. A great number of samples were taken for the estimation of bulk parameters in order to define the status of the ecosystem. Taking account of the time and position of these measurements, selected samples were processed for the analysis of contaminants, which required more effort. Some examples are discussed that illustrate the advantages and disadvantages of the measurement strategy. These focus mainly on hydrographic measurements and nutrient data, reflecting the dominant biological processes investigated during PRISMA.
RNA Interference (RNAi) - An antiviral Strategy for Enteroviruses

Human enteroviruses are a genus of RNA viruses which affects millions of people worldwide each year. They are associated with wide spectrum of diseases ranging from mild respiratory illness like the common cold, hand, foot and mouth disease (HFMD) to more severe neurological and cardiac complications which are fatal. Currently, there is no an effective vaccine or specific antiviral treatment to prevent or treat non-polio enteroviral infections. Since its discovery in 1998, RNA interference has emerged as a potential therapeutic strategy against infectious diseases. In this review, we focus on the developments of using RNAi to prevent or treat enteroviral infections, highlighting the potential of RNAi as a potential antiviral strategy against enteroviruses.
What They Know vs. What They Do: How Acquirers Leverage Technology Acquisitions

Existing research suggests that in acquisitions of small technology based firms by large established firms, post merger integration both enables and hinders acquirer's efforts to leverage the technology of acquired firms. This apparent paradox can be resolved once we account for the qualitatively distinct ways in which acquirers leverage technology acquisitions. Integration helps acquirers use the acquired firm's existing knowledge as an input to their own innovation processes (leveraging what they know), but hinders their reliance on the acquired firm as an independent source of ongoing innovation (leveraging what they do). We also show that experienced acquirers are better able to mitigate the disruptive consequences of the loss of autonomy entailed by integration, though we find no evidence that they achieve greater coordination benefits from integration.
