The effects of streaming in the secondary school on learning outcomes for Australian students – A review of the international literature

This article reviews the international literature about streaming and the effects of this practice on the learning outcomes for secondary school students in Australia. Streaming in secondary schools across Australia has again increased in popularity after more than a century of literature that often discourages the practice. This article discusses the practice of streaming and its effect on students' academic, social and psychological learning outcomes and how teachers may mediate these effects. In addition, the article examines the extent to which the various outcomes of streaming align with the Australian National Curriculum and with the Organisation for Economic Cooperation and Development’s recommendations for promoting equity and quality in education. While research is contentious and often contested, the literature generally shows that streaming impacts negatively on student learning outcomes. The findings of this literature review suggest the need for more research within the Australian context about how teachers’ perspectives of streaming influence learning outcomes and how streaming influences minority and disadvantaged groups in Australia.
Essential‐Oil Composition of the Needles Collected from Natural Populations of Macedonian Pine (Pinus peuce Griseb.) from the Scardo‐Pindic Mountain System

The needle‐terpene profiles of two natural Pinus peuce populations from the Scardo‐Pindic mountain system (Mt. Ošljak and Mt. Pelister) were analyzed. Among the 90 detected compounds, 87 were identified. The dominant constituents were α‐pinene (45.5%), germacrene D (11.1%), β‐pinene (10.8%), and camphene (10.3%). The following eight additional components were found to be present in medium‐to‐high amounts (0.5–10%): bornyl acetate (5.0%), β‐phellandrene (3.4%), β‐caryophyllene (2.9%), β‐myrcene (0.9%), germacrene D‐4‐ol (0.9%), tricyclene (0.7%), (E)‐hex‐2‐enal (0.7%), and bicyclogermacrene (0.6%). Although the general needle‐terpene profiles of the populations from Mt. Ošljak and Mt. Pelister were found to be similar to those of the populations from Zeletin, Sjekirica, and Mokra Gora (Dinaric Alps), principle component analysis (PCA) of eight terpenes (α‐pinene, β‐myrcene, α‐terpinolene, bornyl acetate, α‐terpinyl acetate, β‐caryophyllene, trans‐β‐farnesene, and germacrene D) in 139 tree samples suggested a divergence between the two population groups, i.e., the samples from the Scardo‐Pindic mountain system and those from the Dinaric Alps. Genetic analysis of the β‐pinene content demonstrated a partial divergence between the two geographical groups. The profiles of both population groups differed from those published for populations from the Balkan‐Rhodope mountains system (literature results), which were characterized by high contents of bornyl acetate and citronellol (Greek populations) or δ‐car‐3‐ene (Bulgarian populations).
Response surface methodology

The purpose of this article is to provide a survey of the various stages in the development of response surface methodology (RSM). The coverage of these stages is organized in three parts that describe the evolution of RSM since its introduction in the early 1950s. Part I covers the period, 1951–1975, during which the so‐called classical RSM was developed. This includes a review of basic experimental designs for fitting linear response surface models, in addition to a description of methods for the determination of optimum operating conditions. Part II, which covers the period, 1976–1999, discusses more recent modeling techniques in RSM, in addition to a coverage of Taguchi's robust parameter design and its response surface alternative approach. Part III provides a coverage of further extensions and research directions in modern RSM. This includes discussions concerning response surface models with random effects, generalized linear models, and graphical techniques for comparing response surface designs.

The upper GI safety and tolerability of oral alendronate at a dose of 70 milligrams once weekly: a placebo-controlled endoscopy study

OBJECTIVE:Alendronate (10 mg daily) has been shown in long term clinical trials to be an effective treatment for postmenopausal osteoporosis. A weekly dosing regimen of alendronate is preferred by both patients and physicians, as it has the potential to provide greater convenience and enhance compliance. In a 1-yr clinical trial, alendronate (70 mg once weekly) was equally efficacious and at least as well tolerated as the 10-mg daily dose in the treatment of postmenopausal osteoporosis, despite the higher unit dosage required. We conducted a randomized, double blind, placebo- and active-controlled endoscopy study to confirm the results of this clinical trial. We hypothesized that mean endoscopic gastric erosion scores would be similar in subjects receiving alendronate (70 mg once weekly) and those receiving a placebo.METHODS:Two hundred seventy-seven subjects (90 men and 187 women) were randomized to one of three treatment groups: 1) alendronate (70 mg once weekly) for 10 wk (N = 126), 2) placebo (once weekly) for 10 wk (N = 126), or 3) placebo (once weekly) for 10 wk followed by aspirin (650 mg q.i.d.) for the last week as the positive control (N = 25). Esophagogastroduodenoscopy was performed 5 to 7 days after the last dose of alendronate or matching placebo.RESULTS:The mean gastric erosion scores (Lanza scale) were similar in subjects given alendronate (70 mg once weekly) and those given a placebo (0.32 vs 0.35, respectively; 95% CI for difference =− 0.22–0.16, p = 0.75), whereas scores in both groups were significantly lower than in those given aspirin (3.09; p < 0.001). Endoscopic gastroduodenal ulcers occurred in no alendronate (0%), two placebo (1.7%), and five aspirin (23.8%) subjects. The mean erosion scores in the esophagus and duodenum of alendronate and placebo subjects were also similar. The incidences of upper GI symptoms were similar in the alendronate and placebo subjects and did not suggest a relationship with endoscopic lesions.CONCLUSIONS:Alendronate (70 mg once weekly) was not associated with any increase in endoscopic lesions in the upper GI tract relative to a placebo.
A dynamic approach to phonological assessment

Dynamic and static assessments in phonological disorders provide different information about a child's skills and development. Dynamic assessments evaluate a child's phonological system when given support, whereas static assessments evaluate skills without support. The Scaffolding Scale of Stimulability (SSS), described in this article, is one example of a dynamic assessment used to evaluate phonological disorders. The SSS comprises a 21-point hierarchy of cues and environmental manipulations that can be used to support a child in the production of phonemes. Use of the SSS is illustrated by a case study of a 4-year-old boy with moderate phonological disorder. The SSS is compared to a static assessment, a probe of 60 single words based on the child's error patterns. The two assessments are compared across treatment at three time intervals: prior to treatment, after 3 months of treatment, and after 6 months of treatment. Results indicated that scores on the SSS could differentiate the boy's phoneme productions based on the amount of support needed, while phoneme scores on the probe were at 0% accuracy. As a composite score, the SSS showed a greater percentage of change earlier in treatment and across time when compared to the probe.
Star Formation in NGC 5194 (M51a). II. The Spatially Resolved Star Formation Law

We have studied the relationship between the star formation rate (SFR), surface density, and gas surface density in the spiral galaxy M51a (NGC 5194), using multiwavelength data obtained as part of the Spitzer Infrared Nearby Galaxies Survey (SINGS). We introduce a new SFR index based on a linear combination of Hα emission-line and 24 μm continuum luminosities, which provides reliable extinction-corrected ionizing fluxes and SFR densities over a wide range of dust attenuations. The combination of these extinction-corrected SFR densities with aperture synthesis H I and CO maps has allowed us to probe the form of the spatially resolved star formation law on scales of 0.5-2 kpc. We find that the resolved SFR versus gas surface density relation is well represented by a Schmidt power law, which is similar in form and dispersion to the disk-averaged Schmidt law. We observe a comparably strong correlation of the SFR surface density with the molecular gas surface density, but no significant correlation with the surface density of atomic gas. The best-fitting slope of the Schmidt law varies from N = 1.37 to 1.56, with zero point and slope that change systematically with the spatial sampling scale. We tentatively attribute these variations to the effects of areal sampling and averaging of a nonlinear intrinsic star formation law. Our data can also be fitted by an alternative parameterization of the SFR surface density in terms of the ratio of gas surface density to local dynamical time, but with a considerable dispersion.
Online Learning with Many Experts

We study the problem of prediction with expert advice when the number of experts in question may be extremely large or even infinite. We devise an algorithm that obtains a tight regret bound of $\widetilde{O}(\epsilon T + N + \sqrt{NT})$, where $N$ is the empirical $\epsilon$-covering number of the sequence of loss functions generated by the environment. In addition, we present a hedging procedure that allows us to find the optimal $\epsilon$ in hindsight. Finally, we discuss a few interesting applications of our algorithm. We show how our algorithm is applicable in the approximately low rank experts model of Hazan et al. (2016), and discuss the case of experts with bounded variation, in which there is a surprisingly large gap between the regret bounds obtained in the statistical and online settings.
A study on the virus aetiology of mild respiratory infections in the primary school child

A survey of mild respiratory disease in a primary school was undertaken over a 2-year period to determine which of the newer respiratory viruses were responsible for these illnesses. The over-all isolation rate was low but a wide variety of viral agents was isolated. None of these caused epidemics but it is suggested they may be the cause of a low but constant absentee-rate throughout the year.
Loss of Discrete Memory B Cell Subsets Is Associated with Impaired Immunization Responses in HIV-1 Infection and May Be a Risk Factor for Invasive Pneumococcal Disease1

Invasive pneumococcal infection is an important cause of morbidity and mortality in HIV-1-infected individuals. B cells play an important role in maintaining serologic memory after infection. IgM memory B cells are significantly reduced in HIV-1-infected patients and their frequency is similar to that observed in other patient groups (splenectomized individuals and patients with primary Ab deficiency) who are also known to have an increased risk of invasive pneumococcal infection. Antiretroviral therapy does not restore marginal zone B cell percentages. Immunization with the 23-valent polysaccharide pneumococcal vaccine shows that HIV-1-infected patients have impaired total IgM and IgG pneumococcal vaccines compared with healthy controls. Loss of switched memory B cells was associated with impaired tetanus toxoid IgG vaccine responses. Results of this study demonstrate that defects in B cell memory subsets are associated with impaired humoral immune responses in HIV-1 patients who are receiving antiretroviral therapy and may be a contributory factor to the increased risk of invasive pneumococcal infection observed in HIV-1 infection.
Analyzing the Prosocial Behaviors of Pre-School Children in Accordance with Teacher’s Point of View

This study has been carried out in order to determine the prosocial behaviors of pre-school children. Prosocial behaviors have been analyzed under four categories as cooperation, sharing, collaboration and consolation. This research is a qualitative research having the quality of a descriptive survey model. Teacher interview form has been used as data collection instrument. Working group of this research includes 30 pre-school teachers who work in pre-school education institutions. Research data has been analyzed by using content analysis method. Main titles have been determined by the researcher within the frame of the limitations of the research. Frequency and percentage tables have been created regarding pro-social behaviors under each title. Findings of this research indicate that the most frequent cooperation behavior of the children is to help their friends in putting on or taking out their coats, cardigans or shoes. It also indicates that students generally share their paintings, play dough and toys with their friends; they collaborate while they tidy up their class. Children frequently go up to their friends when they are sad/crying as a consolation behavior.
Maturation of Human Neutrophil Phagosomes Includes Incorporation of Molecular Chaperones and Endoplasmic Reticulum Quality Control Machinery *S

A Human neutrophils are an essential component of the innate immune response. Although significant progress has been made toward understanding mechanisms of phagocytosis and microbicidal activity, a comprehensive analysis of proteins comprising neutrophil phagosomes has not been conducted. To that end, we used subcellular proteomics to identify proteins associated with human neutrophil phagosomes following receptor-mediated phagocytosis. Proteins (n = 411 spots) resolved from neutrophil phagosome fractions were identified by MALDI-TOF MS and/or LC-MS/MS analysis. Those associated with phagocytic vacuoles originated from multiple subcellular compartments, including the cytosol, plasma membrane, specific and azurophilic granules, and cytoskeleton. Unexpectedly several enzymes typically associated with mitochondria were identified in phagosome fractions. Furthermore proteins characteristic of the endoplasmic reticulum, including 11 molecular chaperones, were resolved from phagosome preparations. Confocal microscopy confirmed that proteins representing these major subcellular compartments were enriched on phagosomes of intact neutrophils. Notably calnexin and glucose-regulated protein 78 co-localized with gp91phox in human neutrophils and were thus likely delivered to phagosomes by fusion of specific granules. We conclude that neutrophil phagosomes have heretofore unrecognized complexity and function, which includes potential for antigen processing events.

Density, survival and dispersal of Anopheles gambiae complex mosquitoes in a West African Sudan savanna village

Abstract. To obtain information on adult populations of Afrotropical malaria vector mosquitoes, mark‐release‐recapture experiments were performed with Anopheles females collected from indoor resting‐sites in a savanna area near Ouagadougou, Burkina Faso, during September 1991 and 1992. Results were used to estimate the absolute population densities, daily survival rates, and dispersal parameters of malaria vectors in that area.
Activated Proliferation of B-Cell Lymphomas/Leukemias with the SHP1 Gene Silencing by Aberrant CpG Methylation

Previously we showed reduced protein and mRNA expression of the SHP1 gene in lymphoma/leukemia cell lines and patient specimens by Northern blot, RT-PCR, Western blot, and immunohistochemical analyses. In this study, aberrant methylation in the SHP1 gene promoter was detected in many B-cell leukemia/lymphoma cell lines as well as in patient specimens, including diffuse large B-cell lymphoma (methylation frequency 93%), MALT lymphoma (82%), mantle cell lymphoma (75%), plasmacytoma (100%) and follicular lymphoma (96%) by methylation-specific PCR, bisulfite sequencing, and restriction enzyme-mediated PCR analyses. The methylation frequency was significantly higher in high-grade MALT lymphoma cases (100%) than in low-grade MALT lymphoma cases (70%), which correlated well with the frequency of no expression of SHP1 protein in high-grade (80%) and low-grade MALT lymphoma (54%). It suggests that the SHP1 gene silencing with aberrant CpG methylation relates to the lymphoma progression. SHP1 protein expression was recovered in B-cell lines after the treatment of the demethylating reagent: 5-aza-2′-deoxycytidine. Transfection of the intact SHP1 gene to the hematopoietic cultured cells, which show no expression of the SHP1 gene, induced growth inhibition, indicating that gene silencing of the SHP1 gene by aberrant methylation plays an important role to get the growth advantage of the malignant lymphoma/leukemia cells. The extraordinarily high frequency (75 to 100%) of CpG methylation of the SHP1 gene in B-cell lymphoma/leukemia patient specimens indicates that the SHP1 gene silencing is one of the critical events to the onset of malignant lymphomas/leukemias as well as important implications for the diagnostic or prognostic markers and the target of gene therapy. These data support the possibility that the SHP1 gene is one of the tumor suppressor genes.
Price Ceilings as Focal Points for Tacit Collusion: Evidence from Credit Cards

We test whether a nonbinding price ceiling may serve as a focal point for tacit collusion, using data from the credit card market during the 1980's. Our empirical model can distinguish instances when firms match a binding ceiling from instances when firms tacitly collude at a nonbinding ceiling. The results suggest that tacit collusion at nonbinding state-level ceilings was prevalent during the early 1980's, but that national integration of the market reduced the sustainability of tacit collusion by the end of the decade. The results highlight a perverse effect of price regulation.
Prioritizing areas for quality marker development in children in UK general practice: extending the use of the nominal group technique.

BACKGROUND There is a deficiency in the ability to measure the quality of care of children in primary care and there is no professional consensus in UK general practice regarding which quality markers should be used. OBJECTIVES To prioritize clinical areas on which to focus quality marker development in paediatric primary care and to describe the challenges in generating professional consensus. METHODS We convened an expert panel of GPs with a special interest in child health and using the nominal group technique (NGT), a well-established structured, multistep facilitated group meeting technique, we generated consensus around the key clinical areas to focus quality marker development. RESULTS Twelve GPs participated in the expert panel. The eight items agreed by panellists as most important were early recognition of serious illness, whole practice involvement in safeguarding, health promotion, mental health, evidence-based management of common conditions, child and carer friendliness and safe and cost-effective prescribing. Panel members struggled to balance the broad clinical areas while attempting to focus on specific areas that are important. The main challenges included managing panel uncertainty, effective organization, presentation of items for review and group inclination to 'include everything'. CONCLUSIONS This is the first consensus study of UK GPs to identify key areas to target quality marker development in children. By using the NGT, we have highlighted front-line health care professionals' priorities to improve the quality of care of children and identified the benefits and challenges of developing consensus in a broad topic area.
Ependymal Cell Reactions in Spinal Cord Segments after Compression Injury in Adult Rat

Recently, it has been suggested that neural stem cells and neural progenitor cells exist in the ependyma that forms the central canal of the spinal cord. In this study, we produced various degrees of thoracic cord injury in adult rats using an NYU-weight-drop device, assessed the degree of recovery of lower limb motor function based on a locomotor rating scale, and analyzed the kinetics of ependymal cell proliferation and differentiation by proliferating cell nuclear antigen (PCNA), nestin, glial fibrillary acidic protein (GFAP), or GAP-43 immunostaining. The results showed that the time course of the ependymal cell proliferation and differentiation reactions differed according to the severity of injury, and that the responses occurred not only in the neighborhood of the injury but in the entire spinal cord. An increase in the locomotor rating score was related to an increase in the number of PCNA-positive cells, and the differentiation of ependymal cells into reactive astrocytes was involved in injury repair. No apoptotic cells in the ependyma were detectable by the TUNEL method. These results indicate that the ependymal cells of the spinal central canal are themselves multipotent, can divide and proliferate according to the severity of injury, and differentiate into reactive astrocytes within the ependyma without undergoing apoptosis or cell death.
IL-12 promotes enhanced recovery from vesicular stomatitis virus infection of the central nervous system.

To investigate the role of a cytokine in host defense against the vesicular stomatitis virus (VSV) infection of the central nervous system (CNS), IL-12 was injected i.p. into groups of 10 BALB/c mice on days -1, 0, 1, 2, and 3 postinfection. Four days postinfection, mice were examined. IL-12 strongly enhanced immunity to VSV infection in the CNS as demonstrated by 1) decreased VSV titers in brain homogenate of IL-12-injected mice compared with those of controls; 2) increased expression of inducible nitric oxide synthase in the CNS; 3) enhanced expression of both MHC class I and class II Ags in the CNS; 4) increased T cell infiltration in the CNS, especially in the olfactory bulb; and 5) diminished VSV-induced apoptosis in olfactory bulb. No detrimental effect was observed even with the 200 ng/mouse dose of IL-12. Protective effects of IL-12 were dose dependent. Collectively, these results demonstrate that exogenously added IL-12, even when injected peripherally, significantly enhances recovery from VSV infection of the CNS.
