听力正常人与聋人长时记忆的比较研究

以视觉系列呈现,序列回忆和自由回忆的方法比较了音、形、义三维编码维量在听力正常人与聋人短时记忆和长时记忆加工过程中的相对效用。结果是听力正常组产生了明显的语音相似性效应,聋人组突出地显示出形码的相似性干扰。在短时记忆和长时记忆加工过程中两组被试都显示出了形义两维编码维量的作用最强,而音码的作用相对比较弱。两组被试也都显示出了明显的系列位置效应及大体相同的长时保持。     

Bilingual Language Mixing: Why Do Bilinguals Code-Switch?

Bilingual speakers often code-switch from one language to another, especially when both languages are used in the environment. This article explores the potential theoretical explanations for this language behavior, the costs and benefits associated with language switching, and the role of language dominance in the direction of the switch. In short, code switching follows functional and grammatical principles and is a complex, rule-governed phenomenon. Although significant progress has been made in understanding the psycholinguistics of code switching, research is needed to examine the cognitive mechanisms underlying the bilingual's ability to integrate and separate two languages during the communicative process.     

Ethical Codes in Sports Organizations: An Empirical Study on Determinants of Effectiveness

Confronted with numerous scandals, sports organizations are turning to the adoption of ethical codes to attain more ethical behavior. However, the effectiveness of an ethical code as a means to increase ethical behavior remains debated; furthermore, the particular characteristics of a sports context have not yet been taken into account, nor have the different stages of code establishment been considered in evaluation. This article studies the effectiveness, as measured by the Ethical Climate Index, of ethical codes in sports organizations. Moreover, it investigates the effects of the presence, creation, content, implementation, and enforcement of ethical codes on ethical behavior in sports organizations. Our results shed a light on the conditions that need to be in place to install an effective ethical code in sports organizations: a genuine motivation to improve ethical behavior, the involvement of coaches, and the explicit targeting of the management.     

Our obligations to future generations: the limits of intergenerational justice and the necessity of the ethics of metaphysics

Abstract

Theories of intergenerational justice are a very common and popular way to conceptualise the obligations currently living people may have to future generations. After briefly pointing out that these theories presuppose certain views about the existence, number and identity of future people, I argue that the presuppositions must themselves be ethically investigated, and that theories of intergenerational justice lack the theoretical resources to be able to do this. On that basis, I claim it is necessary to do the ‘ethics of metaphysics’ in order to fully comprehend what, if anything, we may owe future generations. I defend these claims against some important objections.     

What’s wrong with human extinction?

Abstract

This paper explores what could be wrong with the fact of human extinction. I first present four reasons why we might consider human extinction to be wrong: (1) it would prevent millions of people from being born; (2) it would mean the loss of rational life and civilization; (3) it would cause existing people to suffer pain or death; (4) it would involve various psychological traumas. I argue that looking at the question from a contractualist perspective, only reasons (3) and (4) are admissible. I then consider what implications this limitation on reasons has for the wrongfulness of various forms of human extinction.     

Psychometric properties of the Conners-3 and Conners Early Childhood Indexes in a Spanish school population

Ba#ckground/Obje#ctive: To examine the psychometric properties of the Conners 3 ADHD Index (Conners 3 AI) and the Conners Early Children Global Index (Conners ECGI) parents’ form (PF) and teachers’ form (TF) in Spanish schoolers. Method: Two-phase cross-sectional study. In the first phase, information was gathered from teachers (n = 1,796) and parents (n = 882) of 4-5 and 10-11 year-old children. In the second phase (n = 196), children at risk of ADHD and controls were individually assessed. Results: The results confirmed the two-factor structure of the Conners 3 ADHD Index, which contains hyperactive-impulsive and inattentive symptoms, and the two-factor structure of the Conners ECGI PF, consisting of emotional lability and restless-impulsive symptoms. In contrast with the original version, the Conners ECGI TF presented an additional inattentive factor. Moderate-to-high rates of evidence of convergent validity with Child Behavior Checklist and Kiddie-Schedule for Affective Disorders & Schizophrenia, and evidence of external validity (academic achievement) were found. Scores were significantly higher in boys than in girls, for both indexes. Raw scores corresponding to clinical T-scores were higher than the original version. Conclusions: The Conners indexes may be considered reliable and valid instruments for detecting ADHD symptoms in Spanish populations.     

Epidemiological considerations in transgender health: A systematic review with focus on higher quality data

Abstract

Background: High quality data pertaining to the size of the transgender and gender diverse (TGD) population are scant, however, several recently published studies may provide more reliable contemporary estimates.

Aims: To summarize the estimated number and proportion of TGD individuals overall and across age groups, based on most accurate data.

Methods: This systematic review focused on recent studies (published from 2009 through 2019) that utilized sound methodology in assessing the proportion of TGD people in the general population. Publications were included if they used clear definitions of TGD status, and calculated proportions based on a well-defined sampling frame. Nineteen eligible publications represented two broad categories of studies: those that used data from large health care systems; and those that identified TGD individuals from population surveys.

Results: Among health system-based studies, TGD persons were identified using relevant diagnostic codes or clinical notes. The proportions of individuals with a TGD-relevant diagnosis or other recorded evidence ranged between 17 and 33 per 100,000 enrollees. In population surveys TGD status was ascertained based on self-report with either narrow or broad definitions. The survey-based estimates were orders of magnitude higher and consistent across studies using similar definitions. When the surveys specifically inquired about ‘transgender’ identity, the estimates ranged from 0.3% to 0.5% among adults, and from 1.2% to 2.7% among children and adolescents. When the definition was expanded to include broader manifestations of ‘gender diversity’, the corresponding proportions increased to 0.5-4.5% among adults and 2.5-8.4% among children and adolescents. Upward temporal trends in the proportion of TGD people were consistently observed.

Conclusions: Current data indicate that people who self-identify as TGD represent a sizable and increasing proportion of the general population. This proportion may differ, depending on inclusion criteria, age, and geographic location, but well-conducted studies of similar type and design tend to produce comparable results.

幽门螺杆菌cagA基因多态性对临床结局的影响:东亚菌株和西方菌株

CagA蛋白是幽门螺杆菌最重要的毒力因子之一.目前已证实cagA基因存在东亚及西方两种亚型.幽门螺杆菌产生CagA蛋白,注入胃上皮细胞后在其羧基端EPIYA重复序列区进行酪氨酸磷酸化,进而与SHP-2酪氨酸磷酸化酶相互作用,参与上皮细胞的信号传导,导致细胞骨架结构的重排,引起细胞表面形状的改变和细胞动力的增强,造成细胞异常的增殖和运动,在胃癌的发生中起了主要作用.cagA基因的羧基端EPIYA重复序列被认为是区分东亚型和西方型菌株的分子标记,东亚型CagA与SHP-2亲和力大于西方型,最终影响着不同CagA+菌株感染的临床表现.
