Abstract:
Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder, and cognitive flexibility is a sub-component of executive functioning. Studies have shown impairments in cognitive flexibility in ADHD, which is affected by attentional processes. Personality, as a long-standing trait, has a profound effect on ADHD. However, previous studies have not assessed the relationship between attentional function, personality traits, and cognitive flexibility in children with ADHD. This study explored the association between attention networks, personality, and cognitive flexibi

Participants were cued to covertly hold or shift attention among continuous streams of alphanumeric characters and to indicate the parity of target stimuli.

Abstract:
Schizophrenia is a neuropsychological disorder in which the neural systems which regulate attention allocation, primarily the dorsolateral prefrontal cortex, are dysfunctional, resulting in deficient gating of attention to irrelevant inputs from the environment. This sensory processing dysfunction hinders goal-directed behaviour to the extent that the subsequent cognitive deficits of schizophrenia prevent many chronic patients from leading normal lives. It is the onus of neuroscience to understand the nature of deficits induced by the disorder, thus providing target mechanisms for remediation

Executive control is a vital cognitive function that facilitates the focussing and shifting of attention, planning and working towards a goal, ignoring distractions, and flexibly responding to novel situations.

Despite having many effective and well-validated methodologies for detecting and quantifying these deficits, there are very few treatments — pharmacological or otherwise — for ameliorating executive dysfunction.

Traditionally, attentional selection has been thought of as arising naturally from resource limitations, with a focus on what might be the most apt metaphor, e.g. whether it is a ‘bottleneck’ or ‘spotlight’. However, these simple metaphors cannot account for the specificity, flexibility, and heterogeneity of the way attentional selection manifests itself in different behavioural contexts. A recent body of theoretical work has taken a different approach, focusing on the computational needs of selective processing, relative to environmental constraints and behavioural goals.

Abstract:
In recommender systems, graph neural networks (GNN) can integrate interactions between users and items with their attributes, which makes GNN-based methods more powerful. However, directly stacking multiple layers in a graph neural network can easily lead to over-smoothing, hence recommendation systems based on graph neural networks typically underutilize higher-order neighborhoods in their learning. Although some heterogeneous graph random walk methods based on meta-paths can achieve higher-order aggregation, the focus is predominantly on the nodes at the ends of the paths. Moreover, these me

Abstract:
Associative memory based on the Hopfield neural network model can be used directly to store and retrieve information with robustness and error-correction capability. Recently an attentive associative memory was reported which provides the flexibility of rapidly and arbitrarily changing the strengths of the stored images. With slight modification of the conventional retrieving formula we propose a new mechanism for incorporating another kind of attention, i.e., attention-to-bits or the relative significance of each bit in the input images. This relative significance is implemented by multiplyin

Abstract:
Data-driven methods achieved great progress in wide variety of machine vision and data analysis applications due to new possibilities for collecting, annotating and processing huge amounts of data, with supervised learning having the most impressive results. Unfortunately, the extremely time-consuming process of data annotation restricts wide applicability of deep learning in many applications. Several approaches, such as unsupervised learning or weakly supervised learning has been proposed recently to overcome this problem. Nowadays self-supervised learning demonstrates state-of-the-art perfo

Abstract:
In this paper, we present the Sub-Adjacent Transformer with a novel attention mechanism for unsupervised time series anomaly detection. Unlike previous approaches that rely on all the points within some neighborhood for time point reconstruction, our method restricts the attention to regions not immediately adjacent to the target points, termed sub-adjacent neighborhoods. Our key observation is that owing to the rarity of anomalies, they typically exhibit more pronounced differences from their sub-adjacent neighborhoods than from their immediate vicinities. By focusing the attention on the sub

Abstract:
This paper looks at how pension systems across Asia and the Pacific can overcome common challenges of low contributory coverage, inadequate social pensions, and failure to include the informal sector. Pension systems in the region also exhibit gender inequities, a lack of policy flexibility and attention to labor incentives, and underdeveloped governance. The paper reviews the structure and performance of regional pension systems, and makes proposals for an expanded role for social pensions with inclusive targeting, reformed contributory schemes, innovations for the informal sector and women,

Contributed Chapter for Peter B. Dixon and Dale W. Jorgenson (eds.) This chapter provides an overview of the first two decades of the Global Trade Analysis Project (GTAP) – an effort to support a standardized data base and CGE modeling platform for international economic analysis. It characterizes GTAP in four different dimensions: institutional innovation, a network, a database and a standardized modeling platform. Guiding principles for the GTAP modeling framework include flexibility, ease of use, transparency, and symmetric treatment of production and utility fundamentals across regions. Th

Abstract:
United Nations (UN) counter-terrorism (CT) policies are challenged by the emergence and resurgence of different threat profiles on the security horizon because its response framework is focused on one type of terrorism and violent extremism (T/VE) threat. As there is increasing focus on the threat of extreme right-wing T/VE in the current social and political context in the West, for example, the challenges of adaptability and transferability become apparent. This is often due to the lack of flexibility and nuance of the conversation around CT at the UN level. This same lack of consideration f

Abstract:
Scissor frame structures (SFS) have attracted significant attention due to their flexibility of deployment and stiffens once fully deployed. These features benefit prefabrication and transportation over traditional frame structures, with potential for modular structure implementation. However, current research often neglects structural analysis, focusing on geometrical and kinematic designs. This oversight, combined with critical load conditions at the locking mechanism linkage, risk underdesigning the SFS and leading to potential structural failure.

Abstract:
Responding to the COVID-19 pandemic required dramatic changes and new ways of working from civil services around the world. Within this, the immediate pandemic response and shift to remote work have captured most attention, but there has been less analysis of the other ways in which civil services adapted, or of how these changes have shaped the post-pandemic reform agenda. To gain insight on these questions, we interviewed 14 heads of civil service (or other similarly senior officials) from countries on all six continents to understand how they interpret the transformations that have occurred
