心律波动信号具有1/f噪声特性,是非平稳的。该文采用平均功率谱密度方法,分析了基于平均功率谱密度和最小二乘拟合法求正常人和心脏充血患者的心律波动信号的谱参数,发现根据谱参数可以定量地区分正常人与心脏充血患者:大部分正常人的心律波动信号的谱参数大于1,而大部分心脏充血患者的心律波动信号的谱参数小于1,该结论可为心脏病的诊断与预诊断提供一种辅助手段。     

A qualitative investigation of risk and protective factors for interpersonal violence in adults on the autism spectrum

Abstract

Individuals on the autism spectrum are at an increased risk of experiencing violence. This study sought to understand the opinions of adults on the spectrum regarding potential risk and protective factors for interpersonal violence. Twenty-two adults (12 men; 18 to 53 years of age) participated in semi-structured qualitative interviews. Interviews were recorded, transcribed, and analysed. The results of the qualitative analysis identified individual and contextual risk and protective factors. Protective themes focused on individual needs (awareness of the self and the environment, interpersonal knowledge/skills, skill building strategies) and supportive contexts (benefits of a trusted person, advocates, fostering acceptance and inclusion). There is a need for strategies to decrease the vulnerability to, and the impact of, interpersonal violence. Individuals on the spectrum have the capacity to provide important information regarding safety promotion and risk factors for interpersonal violence, and their expertise should play a role in guiding efforts that promote safety.     

‘My Parents told us that they will always Treat my Brother Differently Because he is Autistic’ – Are Siblings of Autistic Children the Forgotten Ones?

Autism spectrum disorder (ASD) does not only affect the child alone, but the family unit as well. This qualitative study explored the impacts of ASD on the relationship between parents and their neuro-typical children and how the neuro-typical children cope with the impacts of having an autistic sibling in the family. Utilising principles of the social relations theory, five Singaporean families (n = 10) consisting of five mothers and five neuro-typical children were interviewed. Both the mothers and the neuro-typical children were seen to be equal agents in influencing the interactions with each other, and contributed in maintaining the close relationship through various strategies. Findings revealed that having an autistic child in the family imposed certain constraints and additional responsibilities for the family members. Despite so, the neuro-typical children coped well with such constraints. The in-depth data highlight the value of considering both the agency of mothers and the neuro-typical children and how they bidirectionally influence each other while sharing the caregiving roles for the autistic child in the family. It is strongly recommended for practitioners to incorporate elements of child's agency when expanding their scope of psychosocial intervention work with the neuro-typical children.     

基于功率约束及节点频谱选择的认知协同路由

为了提升认知无线网络的数据传输效率,优化节点能量负载,提出一种协同路由算法。基于覆盖与底层技术的协作设计一种协同网络架构,该架构针对网络频带表现多样化提供了一种新的频谱选择策略,提升频谱资源效用。结合协同网络频谱选择时的干扰特性,根据频谱、干扰和功率约束关系,提出最大化链路容量的频谱及节点功率分配方法。在协同路由设计上引入了频谱效用参数,参数的度量标准涉及节点剩余能量和链路容量,以优化路由节点能量负载和传输效率为目的。仿真对比结果表明,算法有效地利用信道接入机会进行数据转发,提高了传输效率,相比基于竞争进化算法的多播路由方法,数据包传递成功率提升了1．4％,平均网络吞吐量高出8．4％,平均节点剩余能量高出3．2％,在均衡节点负载上性能良好。     

The experiences of African immigrant mothers living in the United Kingdom with a child diagnosed with an autism spectrum disorder: an interpretive phenomenological analysis

Interpretive phenomenological analysis was used to investigate the experiences of six African immigrant mothers living in the United Kingdom with a child diagnosed with an Autism Spectrum Disorder (ASD). The mothers took part in one-off, semi-structured interviews. Four themes were identified: caring for a child we did not expect, the pain of stigma and rejection, frameworks of meaning, and negotiating conflicting cultural beliefs. Many aspects of the mothers’ experiences appear related to their position as immigrants from cultures with contrasting belief systems regarding child development and disability. Conflicts between African cultural beliefs and a western, medical understanding of ASD appeared to create a feeling of cognitive dissonance for the mothers. The strategies used to negotiate this appear to map onto Berry’s acculturation strategies, suggesting that the experience of having a child with ASD impacts upon the acculturation process. Implications for clinical practice and policy are discussed.     

Fiscal Mapping Autism Spectrum Disorder Funds: A Case Study of Ohio

Individuals with autism spectrum disorders (ASDs) have complex needs requiring regular service utilization. Policymakers, administrators, and community leaders are looking for ways to finance ASD services and systems. Understanding the fiscal resources that support ASD services is essential. This article uses fiscal mapping to explore ASD funding streams in Ohio. Fiscal mapping steps are overviewed to assist ASD stakeholders in identifying and examining ASD-related funding. Implications are drawn related to how fiscal mapping could be used to identify and leverage funding for ASD services. The resulting information is critical to utilizing existing resources, advocating for resources, and leveraging available funds.

Factors That May Influence Parent Treatment Decision Making for Young Children with Autism Spectrum Disorder

ABSTRACT

The number of interventions available for children with autism spectrum disorder (ASD) has expanded greatly in recent years, although relatively little is known about the factors that influence family caregivers as they make treatment decisions for their children. This study involved a statewide survey of parents of young children with ASD to examine the relative weights of the factors that influenced their treatment decisions. Results suggested that caregivers rely on their own intuition for much decision making, although selected professionals are also influential. Implications for professionals working with children with ASD and their families are discussed.

Obsessive-Compulsive Features in Pathological Lottery and Scratch-Ticket Gamblers

The results of this study support the notion that pathological gamblers drawn from the community would score higher on all three scores from the YBOCS than light gamblers. Consistent with hypotheses, pathological gamblers (lottery and scratch ticket) reported more obsessions, compulsions, and avoidance behavior than the light gamblers, and also reported having more urges to engage in injurious behaviors to themselves and others. These findings provide evidence that pathological gambling falls in a spectrum or family of disorders which have obsessive-compulsive disorder at its core. These findings support McElroy, Hudson, Philips, et al.'s (1993) suggestions of similarities between OCD and Impulse Control Disorders, and extend Blaszczynski (1999) findings of overlap between pathological gamblers and OCD in a treatment population. Heavy gamblers also reported significantly more hoarding symptoms and compulsive buying than light gamblers. More research in this area may show further evidence of a spectrum of disorders with obsessive compulsive disorder at its core, and show further links between impulse control disorders (such as pathological gambling) and OCD.
