Parametric Inference in Stationary Time Series Models with Dependent Errors

This article is concerned with inference for the parameter vector in stationary time series models based on the frequency domain maximum likelihood estimator. The traditional method consistently estimates the asymptotic covariance matrix of the parameter estimator and usually assumes the independence of the innovation process. For dependent innovations, the asymptotic covariance matrix of the estimator depends on the fourth‐order cumulants of the unobserved innovation process, a consistent estimation of which is a difficult task. In this article, we propose a novel self‐normalization‐based approach to constructing a confidence region for the parameter vector in such models. The proposed procedure involves no smoothing parameter, and is widely applicable to a large class of long/short memory time series models with weakly dependent innovations. In simulation studies, we demonstrate favourable finite sample performance of our method in comparison with the traditional method and a residual block bootstrap approach.     

Asymptotic theory for fractionally integrated asymmetric power ARCH models

Consistency and asymptotic normality of quasi-maximum likelihood estimators (QMLEs) for the fractionally integrated asymmetric power ARCH (FIAPARCH) process are proved. The moment conditions are assumed only for standardized errors. We show the properties for a wide range of QMLEs including Gaussian QMLE.

The Social Vulnerability Scale for Older Adults: An Exploratory and Confirmatory Factor Analytic Study

The Social Vulnerability Scale (SVS), a 22-item informant report of vulnerability to exploitation and, in particular, financial exploitation of older adults, was administered to 266 respondents who assessed the social vulnerability of a significant other aged 50 years or over, either a person with dementia or other neurological condition (n?=?116), or a healthy adult (n?=?150). Exploratory factor analysis in the combined sample revealed a 15-item two-factor solution labeled gullibility and credulity. Stability in factor structure was established in an independent sample (n?=?123) using confirmatory factor analysis, and sound reliability (internal consistency) and validity (known-groups) were demonstrated. The SVS15 is a potentially useful instrument for assessing older adults' vulnerability to exploitation.     

Ethnosemiotics: Some personal and theoretical reflections

The question of how individual memory fits, or more accurately, does not fit with history is at the heart of this paper on Maryse Condé’s novel Heremakhonon about Veronica Mercier, a character who was born in Guadeloupe, lived in Paris and travels to West Africa in search of an ancestry that was interrupted by slavery. Suggesting that readings that focus on Mercier as a character are limited in approach, it reads the novel as a staging of time and is attentive to the gaps between thought and speech, between memory and history, between Guadeloupe and Africa, and between women’s personal sexual pleasure and the impersonal reproductive body that interrupt the narrative. The central character’s personal quest for her African roots – for ‘niggers with ancestors’, for Africa as a singular lost object, which necessarily involves ignoring the subaltern – is nuanced by the novel’s deployment of heterogeneous time.     

Multimedia Biographies: A Reminiscence and Social Stimulus Tool for Persons with Cognitive Impairment

The multimedia biography tells the story of the life of an elderly person with a cognitive impairment in motion picture format. The multimedia biography combines family photographs, film clips, audio narration, and music. It is intended to be screened on an ongoing basis to provide spaces for reminiscence and communication between cognitively impaired persons and their families. Using a production process in which we collaborated with family caregivers, we created 12 multimedia biographies for persons having Alzheimer's disease or mild cognitive impairment. This article describes our production and screening processes. We also share lessons learned from the multimedia biography research to assist practitioners, families, or researchers who wish to use similar technologies and processes for eliciting and sharing life stories.     

集体记忆：主题拓展与研究展望

集体记忆是一个重要的社会课题,已经有学者在关注和研究它。在未来的集体记忆研究中需要重视主题领域的拓展,应该在宏观层面上重视社会变迁对不同群体集体记忆现象的影响关系,尤其是重视国际化的政治经济联盟、民族争斗、国内文化变迁导致的新群体和边缘群体的集体记忆特点;在微观层次上要超越以往研究的限制和藩篱,在研究主题、视角、方法以及理论建构方面取得更大的突破,促进集体记忆研究的完善和体系化。     

Post-Traumatic Stress Disorder,Dissociation, and Neuropsychological Performance in Latina Victims of Childhood Sexual Abuse

This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning.     

Implications of the Memory Controversy for Clinical Practice: An Overview of Treatment Recommendations and Guidelines

SUMMARY

The controversy surrounding delayed and recovered memories of incest/child sexual abuse has had a profound impact on clinical practice. This article first provides an overview of the positions taken by both sides in the dispute, the “false memory proponents and the traumatic stress proponents”. It then presents the major findings of several of the professional task forces charged with reviewing the controversy and arriving at recommendations for research, clinical practice, and forensic practice regarding delayed recall of memories for sexual abuse. The current status of scientific and clinical knowledge is discussed, especially in terms of its implications for therapists and clinical practice. Nineteen recommendations and practice guidelines are presented for therapists working with individuals who report or suspect childhood sexual abuse on the basis of continuous and/or recovered memory.     

Selective Amnesia: Memory and History of the Urfalli Syrian Orthodox Christians

This article analyzes how a community of Syrian Orthodox Christians (Urfallis), who were forced to emigrate from Urfa to Aleppo in 1924, reconstruct their collective history. These displaced Christians maintain silence about two important events in their history. The reason for their emigration and their participation in the Syrian nationalist movement during the 1930s are either wiped from their memories or deliberately concealed. This selective amnesia is conditioned largely by the complex relationship between the ruling elite, whether French or Syrian, and ordinary Urfallis. The process of historical reconstruction suggests that the ambivalent position of these Christians, which stems from their religious affiliation and immigrant origin, makes them design alternative narratives in order to adapt to the changing political situation whilst they establish a secure position for themselves within Syrian society.
