Latent class models for nonmonotone dichotomous items

Starting from perfectly discriminating nonmonotone dichotomous items, a class of probabilistic models with or without response errors and with or without intrinsically unscalable respondents is described. All these models can be understood as simply restricted latent class analysis. Thus, the estimation and identifiability of the parameters (class sizes and item latent probabilities) as well as the chi-squared goodness-of-fit tests (Pearson and likelihood-ratio) are free of the problems. The applicability of the proposed variants of latent class models is demonstrated on real attitudinal data.This research was supported by the Kulturamt der Stadt Wien, Magistratsabteilung 7.The author wishes to thank the editor, Ivo W.

Construct and concurrent validity of the Cambridge neuropsychological automated tests in Portuguese older adults without neuropsychiatric diagnoses and with Alzheimer’s disease dementia

We aimed to analyze the construct and concurrent validity of the Rapid Visual Information Processing (RVP), Paired Associates Learning (PAL), Reaction Time (RTI), and Spatial Working Memory (SWM) tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB®). Inclusion criteria were checked in a first session. The CANTAB and additional pencil-and-paper tests were administered within 1 week. The participants (aged 69–96 years) were 137 Portuguese adults without neuropsychiatric diagnoses and 37 adults with mild-to-moderate Alzheimer’s disease dementia. Comparisons were made between the CANTAB tests and between these tests and the Rey Complex Figure Test (RCFT), Verbal Fluency (VF) test, and some Wechsler Memory Scale-III and Wechsler Adult Intelligence Scale-III subtests. Most intra-test correlations were stronger than the CANTAB inter-test correlations. The RVP correlated more with VF animals (.44), the PAL with RCFT immediate recall (–.52), the RTI with RVP mean latency (.42), and the SWM with Spatial Span backward (–.39).     

Acute Stress Disorder in Greek Cypriots Visiting the Occupied Areas

Following 30 years of war-driven displacement, in 2003 Cypriots were allowed to visit the occupied areas. The present study investigates whether visiting the occupied areas under peaceful conditions could be a traumatic experience potentially leading to Acute Stress Disorder (ASD). Of the 163 participants who completed self-report questionnaires measuring ASD, depression, anxiety, social support, and stress, 138 visited the occupied areas; out of these, 31 met criteria for ASD, 14 reported experiencing symptoms for over a month and 13 continued to experience symptoms at the time of data collection. Results suggest that visiting the occupied areas may constitute a traumatic experience.     

Non-binary youth: Access to gender-affirming primary health care

ABSTRACT

Background: Transgender (trans) youth who identify outside the gender binary are a growing subpopulation. In this article, we document differences in access to gender-affirming health care between binary and non-binary identified trans youth and explore ways of meeting the health needs of non-binary youth within primary care settings.

Methods: The Canadian Trans Youth Health Survey is a national online survey of trans youth, 14–25 years, conducted in 2013–2014. Among the 839 participants who responded to gender identity items in the survey, 41% identified as non-binary. We compared demographic, health outcome, and health care access responses between non-binary and binary (trans girls/women and trans boys/men) youth.

Results: Non-binary and binary youth were similar in most demographics, including age, geographic distribution, and ethnocultural backgrounds, however a larger proportion (82%) of non-binary youth were assigned female at birth. Older non-binary youth (aged 19–25) were significantly more likely to forego needed healthcare than older binary youth; no significant differences were found between younger (14–18) non-binary and binary youth in foregoing healthcare. Overall, non-binary youth (13%) were significantly less likely than binary youth (52%) to access hormone therapy, but they were more likely than binary youth to report experiencing barriers to accessing hormone therapy when needed.

Conclusions: Non-binary trans youth in Canada report challenges in accessing needed gender-affirming healthcare. Primary care providers are well-situated to integrate a broad range of gender-affirming care services into practice in order to address the unique needs of non-binary youth. Future research is warranted to explore experiences of non-binary youth related to barriers to care and to explore how services can be designed and delivered to better meet the needs of non-binary youth seeking gender-affirming primary care.     

Schreber, Perceval, and Van Gogh: Three Eminent Cases Considered from the Perspective of Four Characteristics of Psychosis

The psychotic dispositions of Schreber, Perceval, and Van Gogh are considered. Four characteristics appear to run through their psychoses, and these are identified and illustrated: (1) Negation, (2) persecutory belief, (3) obedience to a transcendental command, and (4) evangelism/martyrdom. Three of the elements have been identified previously, but evangelism/martyrdom is identified here for the first time. The characteristics tend to move in a linear direction, each reinforcing the psychotic state. Therapy requires a disruption of the path, whether through biochemical or psychosocial means or both.     

On Potentiality And Respect For Embryos: A Reply To Mary Mahowald

In order to understand the nature of human embryos I first distinguish between active and passive potentiality, and then argue that the former is found in human gametes and embryos (even in embryos in vitro that may fail to be implanted) because they all have an indwelling power or capacity to initiate certain changes. Implantation provides necessary conditions for the actualization of that prior, active potentiality. This does not imply that embryos are potential persons that do not deserve the same respect as actual persons. To claim that embryos become persons is to understand the predicate person as a phase sortal, roughly equivalent to adult person. This entails that we would not be essentially persons. In order to explain the traditional understanding of person as a proper sortal rather than a phase sortal, the author distinguishes between proximate and remote potentiality, and shows that, unlike feline embryos, human embryos, by their genetic constitution, possess the remote potentiality to later exercise the typically human activities. It follows that they are already persons essentially.     

Narrative Unity as a Condition of Personhood

Abstract: In this article I critically discuss a claim made by several writers in philosophy and the social sciences that for an individual to count as a person, a single personality, or the subject of a life, the experiences of the subject in question must take a narrative form. I argue that narrativity is a misleading and, in some ways of understanding it, implausible condition of what it is that adds unity to personhood and personality. I pursue this critique by considering canonical accounts of narrativity in philosophy and literary studies. I consider those connections between events that must hold for the sequence to be considered a narrative: causal, teleological, and thematic connections. I argue that for each of these, the condition that experiential sequences (for a given subject) must have this structure is empty: any life sequence that is reflected upon in an interpretive spirit can meet it. What the condition of narrativity amounts to, then, is the more basic requirement that the person must be able to look upon the factors and events of her life with a certain interpretive reflection, whether or not those factors and events have any particular narrative unity in a traditional sense.     

群体印象形成与个体印象形成：反基准比率效应

采用 “反基准比率效应”范式考察在群体印象形成与个体印象形成两种认知加工过程中, 基准比率对印象形成过程及其结果的影响。被试分别为39名19~25岁大学生(实验1：男生17名, 女生22名, 均为右利手)以及46名19~25岁大学生(实验2：男生21名, 女生25名, 均为右利手)。结果发现：无论是群体印象形成还是个体印象形成, 在学习阶段, 知觉者都能准确认知各类事件间的关系, 但会优先建构高频事件间的联结。而在测试阶段, 当低频事件与高频事件同时出现时, 知觉者发生明显关系误判, 即以反基准比率的倾向高估低频事件间的联结强度。实验表明群体与个体印象形成过程中都会产生反基准比率效应这样的加工偏差, 进而初步揭示反基准比率现象在社会信息加工领域具有一定的普遍性。     

Distance patterns and disposal sites in rural area homicides committed in Finland

The present study examined offender characteristics, distance patterns, and the nature of disposal sites in rural area homicides. Pre‐trial investigation files of cases where victims' bodies were found in rural areas in 1994–2005 (n = 46) and forensic psychiatric examination reports of the offenders were content‐analysed. Psychopathy Check List‐Revised was used to assess psychopathy. Investigators of these homicides filled out a questionnaire on the offender's familiarity with the body disposal area, and MapInfo was used to measure offender/victim‐residence‐to‐crime‐to‐body‐disposal‐site distances. Rural area homicides more frequently involved multiple offenders who were significantly younger than offenders in other homicides. Of the victims, 73% were found in woods and 27% in water. Offenders were familiar with disposal sites in over half of the cases. The victim's gender, close relationship with the offender, and the offender's violent crime history were associated with longer homicide‐scene‐to‐body‐disposal‐site distances. The number of inhabitants and offender's violent crime history were related to longer offender‐residence‐to‐body‐disposal‐site distances. Offender's age, intelligence, or psychopathology bore no significant association with the distance patterns. The results can be applied when searching missing persons in homicide investigations and in prioritising suspects in rural area homicides. Copyright © 2008 John Wiley & Sons, Ltd.
