    This paper introduces a new subclass of p−valent functions of complex order which is denoted by Sp(b, λ, α) with 0 ≤ λ ≤ 1 and α > 1. The coefficient inequality and Fekete-Szeg¨o inequality for functions f belongs to this class are obtained

    Kv4 potassium channels modulate hippocampal EPSP-spike potentiation and spatial memory in rats

    International audienceKv4 channels regulate the backpropagation of action potentials (b-AP) and have been implicated in the modulation of longterm potentiation (LTP). Here we showed that blockade of Kv4 channels by the scorpion toxin AmmTX3 impaired reference memory in a radial maze task. In vivo, AmmTX3 intracerebroventricular (i.c.v.) infusion increased and stabilized the EPSP-spike (E-S) component of LTP in the dentate gyrus (DG), with no effect on basal transmission or short-term plasticity. This increase in E-S potentiation duration could result from the combination of an increase in excitability of DG granular cells with a reduction of GABAergic inhibition, leading to a strong reduction of input specificity. Radioactive in situ hybridization (ISH) was used to evaluate the amounts of Kv4.2 and Kv4.3 mRNA in brain structures at different stages of a spatial learning task in naive, pseudoconditioned, and conditioned rats. Significant differences in Kv4.2 and Kv4.3 mRNA levels were observed between conditioned and pseudoconditioned rats. Kv4.2 and Kv4.3 mRNA levels were transiently up-regulated in the striatum, nucleus accumbens, retrosplenial, and cingulate cortices during early stages of learning, suggesting an involvement in the switch from egocentric to allocentric strategies. Spatial learning performance was positively correlated with the levels of Kv4.2 and Kv4.3 mRNAs in several of these brain structures. Altogether our findings suggestthat Kv4 channels could increase the signal-to-noise ratio during information acquisition, thereby allowing a better encoding of the memory trace

    Adapting measures of social climate for use with individuals with intellectual developmental disability in forensic settings

    The social climate of forensic settings is thought to impact on a number of important clinical and organisational outcomes and is, therefore, an important construct in relation to the successful functioning of forensic units. A variety of self-report questionnaires have been developed to objectively measure the social climate of forensic settings (e.g. the Correctional Institutions Environment Scale and the Essen Climate Evaluation Schema), however these questionnaires have not been validated for individuals with intellectual developmental disabilities (IDD). Given the prevalence of IDD in prison and forensic psychiatric settings and the potential impact of such cognitive deficits on the ability to complete a range of self-report questionnaires, it is important to consider the potential reliability and validity of existing social climate measures in IDD populations. This article will, therefore: 1) examine the cognitive, linguistic and response format difficulties that may arise when administering self-report measures of social climate in IDD populations; 2) consider potential adaptations to existing measures of social climate that might make them more suitable for use with IDD populations; and 3) identify important directions for future research in the area

    Do students value feedback? Student perceptions of tutors' written responses

    Get PDF
    The topic of feedback to students is an under-researched area, and there has been little empirical research published which focuses on student perceptions. This study explores student perceptions of written feedback and examines whether feedback received demonstrated a student-centred approach to learning. A multi-method approach of qualitative and quantitative data collection and analysis was used to survey 44 students in the faculties of Business and Art & Design. Student responses show feedback is valued, but believed tutor comments could be more helpful. Survey results indicate that students may need advice on understanding and using feedback before they can engage with it. Content analysis of feedback samples and student responses uncovered four main themes of feedback considered unhelpful to improve learning: comments which were too general or vague, lacked guidance, focused on the negative, or were unrelated to assessment criteria. It is suggested that by focusing on messages conveyed by their writing, providing feedback set in the context of assessment criteria and learning outcomes, and by ensuring that it is timely, tutors could greatly improve the value of feedback

    Progress in development of nanostructured manganese oxide as catalyst for oxygen reduction and evolution reaction

    The rise in energy consumption is largely driven by the growth of population. The supply of energy to meet that demand can be fulfilled by slowly introducing energy from renewable re-sources. The fluctuating nature of the renewable energy production (i.e., affected by weather such as wind, sun light, etc.), necessitates the increasing demand in developing electricity storage systems. Reliable energy storage system will also play immense roles to support activities related to the internet of things. In the past decades, metal‐air batteries have attracted great attention and interest for their high theoretical capacity, environmental friendliness, and their low cost. However, one of the main challenges faced in metal‐air batteries is the slow rate of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) that affects the charging and the discharging performance. Various types of nanostructure manganese oxide with high specific surface area and excel-lent catalytic properties have been synthesized and studied. This review provides a discussion of the recent developments of the nanostructure manganese oxide and their performance in oxygen reduction and oxygen evolution reactions in alkaline media. It includes the experimental work in the nanostructure of manganese oxide, but also the fundamental understanding of ORR and OER. A brief discussion on electrocatalyst kinetics including the measurement and criteria for the ORR and the OER is also included. Finally, recently reported nanostructure manganese oxide catalysts are also discussed
