Educating students with special needs in inclusive settings has become a priority for westernized governments as they strive to create more inclusive societies. While recognizing the societal benefits of inclusion, teachers and parents question whether or not implementation of full inclusion will come at the expense of learners’ individual needs. This is particularly true for students with cognitive disabilities moving into the content-rich, peer-dominated environment of secondary school. It will be maintained within this article that there remains a need for segregated classrooms where students with mild cognitive disabilities can receive the specialized programming and supports that they require in a low-stress environment. Furthermore, educators should continue to prioritize the learning needs of all students with disabilities when contemplating full inclusion. Modeling an inclusive society should not mean inclusion at all costs, but considering what’s best for each student and recognizing that one size does not fit all.  相似文献

Drugs and the Brain: A Serious Game, a prototype museum exhibit, was designed to employ virtual models of the brain into a video game format. It was done to create a fun and engaging way of conveying knowledge and concepts about neuroscience, as well as the impact of methamphetamine abuse on the brain. The purpose of this study is to evaluate this prototype exhibit that promises to educate participants from various age, ethnicity, and gender backgrounds, and to establish a stronger concept of drug abuse prevention among children. A quantitative methodology using the pre‐ and post‐experimental designs was conducted on 175 museum visitors. A series of two‐sample paired t‐tests and subsequent ANOVAs were performed to examine the difference between pre‐ and post‐tests and to determine if there was a difference in the results in age, gender, ethnicity, and race. Results showed that both the understanding and attitudes of the participants toward the impact of methamphetamine abuse on the brain improved significantly (p < 0.01).  相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.  相似文献

Artificial rugby union playing surface installation is increasing. This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9–91.7) and on grass 81.9 per 1000 match-hours (CI 72.2–92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82–1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 – 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05–4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors.  相似文献

The sociology of education in New Zealand, as in other countries, is affected by the dilemma inherent to the discipline, namely: is it a sociology of education or a sociology for education? In this article I analyse three factors in which the dilemma is played out: ‘cultural oppositionism’ in the indigenous (kaupapa Maori) approach, critical policy research and the role of empirical research. I argue that a sociology for education is fundamentally weakened by its politicisation, a flaw not helped by the difficulties in drawing political goals from moral imperatives. In contrast a sociology of education, which uses the strengths of empirical research and theoretical analysis, offers the better hope of renewal for, what is, in New Zealand, a moribund discipline.  相似文献

This article discusses an assessment and deselection project of the modern print book collections in the John Paul II Library, National University of Ireland Maynooth. Following a contextual introduction and literature review, the article outlines the methodology, presents and discusses the results, and concludes with lessons learned. Although this project had its origins in planning for a major extension to the Library, its main aim was to ensure current and relevant print book collections. The purpose of the article is to share experience in the hope of it being useful to other libraries considering a review of print book collections.  相似文献

Abstract

In two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design.  相似文献

Purpose: There is a paucity of research investigating the expression of mitogen-activated protein kinases (MAPK) in chronically trained (CT) athletes. Thus, it is unclear how MAPK may contribute to performance and muscle adaptation in CT subjects. The purpose of this study was to determine MAPK total protein, and phosphorylated expression of extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38-MAPK (p38) between untrained, and chronically trained runners. Methods: Tissue samples were analysed from sedentary (SED; n?=?5) controls and chronically trained runners (CT; n?=?5). Resting muscle biopsy samples were analysed for total-MAPK – and ratio of phosphorylated/total (p-MAPK) – ERK1/2, JNK, and p38-MAPK via western blotting. Mann–Whitney U tests and effect sizes were utilized to determine differences in total MAPK protein content and phosphorylation status between SED and CT subjects. Results: There was no difference in total-MAPK expression between SED and CT (p?>?.05). p-p38-MAPK tended to be greater for CT compared to SED (p?=?.07). There were moderate effect sizes of decreased pERK/total-ERK (d?=??0.69) and increased pJNK/total-JNK (d?=?0.54) in CT compared to SED. There was a positive correlation between p-p38-MAPK/total-MAPK and the percentage of type I fibres (r?=?0.73, p?=?.016). Conclusion: Contrary to previous studies, chronic endurance training does not greatly influence total MAPK protein expression in chronically trained runners. However, resting phosphorylation of p38-MAPK may contribute to enhanced oxidative metabolism at chronically trained levels. These alterations are likely involved in the different physiological adaptations that occur following long-term training or at highly competitive levels.  相似文献

This content analysis reveals that men and women network news correspondents differed in how they covered 4 presidential elections (1992–2004). There were fewer women than men reporters involved in election coverage, but on average, women reported more stories than men and were tonally tougher watchdogs than men. In terms of framing candidates, male reporters were strongly associated with a masculine approach that emphasized the competitiveness of campaigns. By contrast, women correspondents employed both more feminine and gender-neutral frames than their male colleagues. These findings were interpreted against the backdrop of information derived from in-depth interviews with 5 women reporters who appeared in the sampled content.  相似文献

Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic memory and volume of subregions (head, body, and tail) of the hippocampus—a structure known to support episodic memory in school‐aged children and adults—during early childhood (= 45). Results revealed significant positive relations between episodic memory and volume of the hippocampal head in both the left and right hemispheres for 6‐ but not 4‐year‐old children, suggesting brain–behavior relations vary across development. These findings add new information regarding neural mechanisms of change in memory development during early childhood and suggest that developmental differences in hippocampal subregions may contribute to age‐related differences in episodic memory ability.  相似文献
