Setting evaluation and assessment criteria for primery students' fine art products

Field: Arts and Humanities (Social Sciences)

Setting criteria for evaluating and assessing pupil's artwork is a major problem for grade level teachers. Questions arise, such as: What should I appreciate in student’s artwork? How can I examine it? And How do I get the criteria for assessment? It would be difficult to give a more precise answer on this issue. There is no general rule for setting criteria for evaluation and assessment of pupil’s artwork. Evaluation and assessment can be poorly structured, poorly understood and uncoordinated. Without clearly defined intentions and aims, accurate measurement of pupil’s achievements may not be reliable. We choose the criteria based on the appropriate art task. We choose the criteria based on the general and specific goals of visual art syllabus and from the operational goals of each art task. We derive from the specificity of visual art education on grade level and from special contents of visual art education of each individual grade level, considering children’s artistic development. \nIn the empirical part, we examined the assessment od state of setting criteria and which criterion are considered most suitable for grade level teachers for evaluation and assessment of artwork. We have explored whether teachers consider artistic development, curriculum and artistic expression when assessing pupils. We investigated whether there are differences in the choice of criteria between teachers from first to fifth grade, between teachers with different length of working and between grade teachers and art teachers. We made a survey questionnaire containing five art tasks. For each art task from each art field, the respondents chose among the given criteria, taking into account the analysis of curriculum, the artistic development of children, the visual expression and analysis of manuals, textbooks and their recommended lesson plans. \n
Polarographic measurement of ascorbate washout in isolated perfused rabbit hearts

Field: Medicine (Health Sciences)

To study the myocardial washout of ascorbate, the applicability of polarographic detection of ascorbate ions by a platinum electrode (sensitive area 0.03 mm2) was investigated, in both a calibration setup (sampling flow along the electrode: 100 microliter X s-1) and isolated, retrogradely perfused rabbit hearts. In the calibration setup at pH 7.4, the sensitivity of the electrode was 70 microA/mol. This sensitivity increased moderately with increasing pH (13%/unit pH) and increasing sampling flow rate (14% at an increase from 100 to 150 microliter X s-1). In the isolated hearts, ascorbate infused into the aorta was detected in a right ventricular drain by the electrode as well as by the use of 14C-labeled ascorbate. Both recorded time courses were similar except for a scaling factor dependent on flow velocity. During continuous infusion the arteriovenous difference of ascorbate was 2 +/- 2% (SD), indicating a relatively low consumption of ascorbate by the isolated heart. We conclude that polarographic measurement of ascorbate in the coronary effluent of an isolated rabbit heart can be performed on-line and relatively easily.
Sodium valproate and thrombocytopenia.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Sodium valproate and thrombocytopeniaPublished reports on the value of sodium valproate (Epilim) as an anticonvulsant drug have been encouraging.'Acquired platelet function defects ofdoubtful significance have been found and attributed to this drug,2 and there have been two reports of haemorrhages, prolonged bleeding times, and thrombocytopenia in patients on sodium valproate with other anticonvulsant drugs.3 4 The patient we report here developed thrombocytopenia when taking sodium valproate alone, and the investigations are recorded. Case reportA 6-year-old boy weighing 20 kg had been having major and minor seizures for two years and had failed to respond to other anticonvulsant drugs.On treatment with sodium valproate 400 mg four times a day, all other drugs having been stopped, he was rendered fit-free for eight months.His mother then reported that he had developed hair loss and multiple spon- taneous bruises.The bleeding time was prolonged and the platelet count was 15 x 109/1, but other tests of coagulation were normal.Sodium valproate was immediately discontinued.The serum level at this time was very high
The small GTP-binding protein Cdc42 is required for nerve growth factor withdrawal-induced neuronal death

Field: Neuroscience (Life Sciences)

An increase in the level of the c-Jun transcription factor and of its phosphorylation has previously been shown to be essential for nerve growth factor (NGF) withdrawal-induced apoptosis of rat sympathetic neurons (SCG). The Rho-like GTPases Cdc42 and Rac1 are involved in the regulation of a number of cellular processes, including activation of the c-Jun NH 2 -terminal kinase (JNK) pathway. Therefore, we have investigated the role of these GTPases in this process. Overexpression of activated Rac1 or Cdc42 in SCG neurons maintained in the presence of NGF induced apoptosis, whereas expression of dominant negative mutants of Cdc42 or Rac1 blocked apoptosis following NGF withdrawal. Cdc42 activation produced an increase in the level of c-Jun and of its phosphorylation. Furthermore, Cdc42-induced death was prevented by coexpressing the c-Jun dominant negative FLAGΔ169. Thus, Cdc42 appears to function as an initiator of neuronal cell death by activating a transcriptional pathway regulated by c-Jun.
Losartan reduces the immediate and sustained increases in muscle sympathetic nerve activity after hyperacute intermittent hypoxia

Field: Medicine (Health Sciences)

Obstructive sleep apnea (OSA) is characterized by intermittent hypoxemia, which produces elevations in sympathetic nerve activity (SNA) and associated hypertension in experimental models that persist beyond the initial exposure. We tested the hypotheses that angiotensin receptor blockade in humans using losartan attenuates the immediate and immediately persistent increases in 1) SNA discharge and 2) mean arterial pressure (MAP) after hyperacute intermittent hypoxia training (IHT) using a randomized, placebo-controlled, repeated-measures experimental design. We measured ECG and photoplethysmographic arterial pressure in nine healthy human subjects, while muscle SNA (MSNA) was recorded in seven subjects using microneurography. Subjects were exposed to a series of hypoxic apneas in which they inhaled two to three breaths of nitrogen, followed by a 20-s apnea and 40 s of room air breathing every minute for 20 min. Hyperacute IHT produced substantial and persistent elevations in MSNA burst frequency (baseline: 15.3 ± 1.8, IHT: 24 ± 1.5, post-IHT 20.0 ± 1.3 bursts/min, all P < 0.01) and MAP (baseline: 89.2 ± 3.3, IHT: 92.62 ± 3.1, post-IHT: 93.83 ± 3.1 mmHg, all P < 0.02). Losartan attenuated the immediate and sustained increases in MSNA (baseline: 17.3 ± 2.5, IHT: 18.6 ± 2.2, post-IHT 20.0 ± 1.3 bursts/min, all P < 0.001) and MAP (baseline: 81.9 ± 2.6, IHT: 81.1 ± 2.8, post-IHT: 81.3 ± 3.0 mmHg, all P > 0.70). This investigation confirms the role of angiotensin II type 1a receptors in the immediate and persistent sympathoexcitatory and pressor responses to IHT. NEW & NOTEWORTHY This study demonstrates for the first time in humans that losartan, an angiotensin receptor blocker (ARB), abrogates the acute and immediately persistent increases in muscle sympathetic nerve activity and arterial pressure in response to acute intermittent hypoxia. This investigation, along with others, provides important beginning translational evidence for using ARBs in treatment of the intermittent hypoxia observed in obstructive sleep apnea patients.
Lipid profile in women receiving depot medroxyprogesteron acetate as contraceptive.

Field: Medicine (Health Sciences)

The study was conducted to estimate the serum lipid levels in women using depot medroxyprogesterone acetate (DMPA). A total of 90 Bangladeshi married women of age group 15-40 years attending the Model Family Planning Clinic, Mymensingh Medical College Hospital, Mymensingh, from July 2010 to June 2011. Patients were classified into three groups comprising those using the drug for 3 months (n=30), 1 year (n=30), and 2 years (n=30), respectively, compared to a control group (n=30) of married non-hormonally treated women of similar ages. Their age, weight, height, BP and BMI were recorded; all the subjects were clinically examined. Blood samples were collected for biochemical assay of serum lipid profiling parameters, such as total cholesterol, HDL-C, TAG and LDL-C. Data were collected and processed according to the design and objectives of the study. A significant (p<0.01) decrease in serum total cholesterol was observed up to 1 year of using DMPA, but a sharp increase was observed in 2 years group. Likewise total cholesterol, HDL-C was significantly (p<0.01) decreased in the 1 year group and rapidly increased in the 2 years group. A significant (p<0.01) reduction in TAG level was observed throughout the study tenure when compared with control group. No significant (p>0.05) difference in LDL-C level was observed among the treatment groups. The study concludes that DMPA induced significant alterations in lipid profiling parameters of the studied population and prolong use does not have risk of atherosclerosis; however, further study with a larger sample size is suggested for a general recommendation.
Proof-of-Concept Demonstration Results for Robotic Visual Servo Controllers

Field: Engineering (Physical Sciences)

There is significant motivation to provide robotic systems with improved autonomy as a means to significantly accelerate deactivation and decommissioning operations while also reducing the associated costs, removing human operators from hazardous environments, and reducing the required burden and skill of human operators. To achieve improved autonomy, fundamental research is focused on the challenges of developing visual servo controllers. The challenge in developing these controllers is that a camera provides 2-dimensional image information about the 3-dimensional Euclidean-space through a perspective (range dependent) projection that can be corrupted by uncertainty in the camera calibration matrix. Disturbances in this relationship (i.e., corruption in the sensor information) propagate erroneous information to the feedback controller of the robot, leading to potentially unpredictable task execution. This technical manual describes 3 proof-of-concept demonstrations of visual servo controllers developed from fundamental research aimed at these challenges. Specifically, one section describes the implementation of a cooperative visual servo control scheme with a camera-in-hand and a fixed camera to track a moving target despite uncertainty in the camera calibration and the unknown constant distance from the camera to a target where the camera is mounted on the end-effector of a 6 degrees-of-freedom hydraulic robot manipulator. The next section describes the implementation of 2 homography-based visual servo tracking and regulation controllers for a mobile robot with a calibrated camera despite an unknown time-varying distance from the camera to a target.
Large deviations of the empirical volume fraction for stationary Poisson grain models

Field: Mathematics (Physical Sciences)

We study the existence of the (thermodynamic) limit of the scaled cumulant-generating function L<sub>n</sub>(z)=|W<sub>n</sub>|<sup>−1</sup>logEexp{z|Ξ∩W<sub>n</sub>|} of the empirical volume fraction |Ξ∩W<sub>n</sub>|/|W<sub>n</sub>|, where |⋅| denotes the d-dimensional Lebesgue measure. Here Ξ=⋃<sub>i≥1</sub>(Ξ<sub>i</sub>+X<sub>i</sub>) denotes a d-dimensional Poisson grain model (also known as a Boolean model) defined by a stationary Poisson process Π<sub>λ</sub>=∑<sub>i≥1</sub>δ<sub>X<sub>i</sub></sub> with intensity λ>0 and a sequence of independent copies Ξ<sub>1</sub>,Ξ<sub>2</sub>,… of a random compact set Ξ<sub>0</sub>. For an increasing family of compact convex sets {W<sub>n</sub>, n≥1} which expand unboundedly in all directions, we prove the existence and analyticity of the limit lim <sub>n→∞</sub>L<sub>n</sub>(z) on some disk in the complex plane whenever Eexp{a|Ξ<sub>0</sub>|}<∞ for some a>0. Moreover, closely connected with this result, we obtain exponential inequalities and the exact asymptotics for the large deviation probabilities of the empirical volume fraction in the sense of Cramér and Chernoff.

RELEVANCE OF RATER‐RATEE ACQUAINTANCE IN THE VALIDITY AND RELIABILITY OF RATINGS1

Field: Psychology (Social Sciences)

Unacquainted S s worked in three‐man groups under relevant (mathematical tasks) and irrelevant (socializing) acquaintance conditions. The S s rated one another on scales that defined several cognitive skills. They were also rated on these same scales by observers who were dependent on visual information, exclusively, and were unacquainted with the group members or the specific nature of the tasks being performed. As hypothesized, group members under the relevant acquaintance condition achieved consistently good validity for all three cognitive areas—with the best validity for ratings of math ability. Validity under the irrelevant acquaintance condition was nil on all scales. Observers, surprisingly, achieved significant validity (although at lower levels than participating group members) for ratings under the relevant acquaintance condition. Levels of inter‐ and intrarater reliability were not associated with levels of validity under the various rating conditions.
Research on Modeling of Cutting Wire Deflection of Multi-Wire Saw

Field: Engineering (Physical Sciences)

The deflection of cutting wire on multi-wire saw is determined by cutting wire tension, diameter ingot feed force and some other factors, and it affects the quality of silicon wafers greatly. In this paper, the initial stage of cutting process is analyzed and modeled with three ODEs. Then the numerical solutions are solved by finding out the BVPs of each ODE. The numerical solutions showed the relationship between the deflection and the cutting parameters such as cutting wire tension, diameter and ingot feed force. This method is helpful for the further research of modeling the entire cutting process.

Edwardsiellosis in farmed turbot, Scophthalmus maximus (L.), associated with an unusual variant of Edwardsiella tarda: a clinical, aetiological and histopathological study

Field: Veterinary (Health Sciences)

Abstract During 2005 and 2010, a survey of edwardsiellosis on eight turbot, Scophthalmus maximus (L.), farms was conducted in China. This report presents the detailed results of the study on this disease. Diseased turbot displayed two distinct types of gross signs: black discoloration of the dorsal skin on the posterior portion of the body; and red cutaneous foci on the ventral side. Internally, the most pronounced clinical signs in all fish examined were enlarged kidneys. The causal agent of the disease was finally proved to be one species of bacterium that was identified as E dwardsiella tarda by physiological and biochemical tests, API 32E and 16S ribosomal RNA sequence analysis. It is noteworthy that unlike the commonly described E. tarda strains, the isolates in this study were non‐motile strains without flagella. A histopathological study revealed that E. tarda infection was systemic in turbot and that kidney showed the most significant pathological changes, including acute focal necrosis, an influx of macrophages and formation of granuloma. The most common histopathological characteristics of this disease are the proliferation of macrophage in various organs and formation of granuloma. In addition, this article also gave background information on the disease and presented the results of virulence tests with the E. tarda strain identified in this study.
SEPSIS IN POST-PCNL PATIENTS; RISK FACTORS AND INFLUENCE OF STONE CULTURES.

Field: Medicine (Health Sciences)

Objective: Post-operative sepsis is a well known complication of various endourologic procedures especially PCNL and it is caused by stone fragmentation containing toxins and bacteria with subsequent toxaemia and bacteremia. The present study was to determine clinical role of stone culture in modifying treatment and assess the factors that may increase the risk to develop sepsis after PCNL . Methods: A total of 211 patients (119 males and 92 females) with a mean age of 38.2 years were enrolled in this study at our single centre tertiary care institute . Patients with preoperative positive urine culture and sensitivity were excluded . All patients received prophylactic 3rd generation cephalosporin intravenously at the time of anaesthesia induction. Stone culture was taken from all patients after puncturing the pelvicalyceal system and sent for culture and sensitivity. Patients were monitored closely in the postoperative period for the development of SIRS. Risk factors such as diabetes, age, degree of hydronephrosis, residual fragments, number of access points PCNL type (standard versus mini) and stone burden were evaluated for the association with SIRS. Results: Mean duration of the operations was 82.7 min (30 to 110 min. ). 19 patients(9.0 %) developed post PCNL SIRS Stone culture identied organisms in8 patients(42% of patient cohort ). Treatment plan was changed as per antibiotic culture sensitivity in only one patientwith culture sensitivity report in three patients being multi drug resistant and rest responded to antibiotics they were receiving already. Statistically signicant factors for post PCNL fever were diabetes mellitus (DM) (p = 0.001), stone burden (p = 0.004), and degree of hydronephrosis (p = 0.04). Conclusion: Doing intraoperative stone cultures sensitivity does not confer additional benet for antibiotic change in majority of cases.DM, staghorn stones, degree of hydronephrosis, duration of the operation and number of tracts are risk factors for post PCNL SIRS.
Mechanisms underlying calcium homeostasis in isolated hepatocytes.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The steady state relationship between intra- and extramitochondrial free Ca2+ across the inner mitochondrial membrane has been investigated in isolated liver mitochondria. The extramitochondrial free Ca2+ concentration was essentially independent of the mitochondrial calcium content above 4 nmol/mg of protein. Below this value, a decrease in the mitochondrial calcium content was accompanied by a decrease in the extramitochondrial free Ca2+ concentration. The experimental data are compatible with a model in which the steady state distribution of calcium is described in terms of the kinetic parameters of the separate carriers catalyzing Ca2+ influx and efflux across the mitochondrial inner membrane. The corresponding relationship between cytosolic free Ca2+ concentration and the amounts of calcium in the mitochondria and endoplasmic reticulum was investigated in isolated river cells over a range of cellular Ca2+ contents by using a nondisruptive technique based on the selective release of calcium from mitochondrial and total cellular pools by addition of carbonyl cyanide p-trifluoromethoxyphenylhydrazone and A23187, respectively. A net increase in cell calcium from 1 to 5 nmol/mg dry weight, increased the cytosolic free Ca2+ concentration from 0.1 to about 0.3 microM and increased the calcium contents of both mitochondria and endoplasmic reticulum. Above 5 nmol of calcium/mg cell dry weight, the endoplasmic reticulum calcium pool became filled, and further increases in calcium content were accounted for by increases of the mitochondrial pool but no further increase of the cytosolic free Ca2+ concentration. These studies and experiments with mixtures of isolated microsomes and mitochondria suggest that, in cells as normally isolated (containing 5 to 6 nmol of calcium/mg dry weight), the endoplasmic reticulum is saturated with calcium and is unlikely to play a major role as an intracellular calcium buffer. The in situ mitochondrial calcium content is sufficiently high (approximately 16 nmol/mg of protein) for these organelles to buffer effectively the cytosolic free Ca2+ concentration at a value of about 0.3 microM. In addition, it may be concluded that intramitochondrial Ca2+-dependent enzymes will be exposed to saturating concentrations of free Ca2+.
