Missing piece of the puzzle in the science of consciousness: Resting state and endogenous correlates of consciousness

Consciousness still stands as one of the most interesting and the most elusive problems of neuroscience. Finding its correlates is the first step toward its satisfactory explanation. Several theories have proposed its correlates but none of them seem to be generally accepted even though most of them share some very similar elements. These elements are the activity of the thalamus, which is considered by some as the central region for consciousness, and gamma synchronization, which should be the general principal for the emergence of conscious experience. However, all of these proposed theories share one characteristic and that is that they do not take into consideration the recently discovered endogenous activity of the brain, which is generally associated with the default mode network. Although the activity of this large scale brain network is in correlation with various levels of consciousness it is still missing in discussions of consciousness. This review recognizes the importance of endogenous activity and points out the important discoveries of endogenous activity that could be an important step toward a satisfactory explanation of consciousness.     

Minorities and the Philosophical Marketplace

This article argues for two theses. The first is that many of the sociological factors endemic in the philosophical community function as barriers to the recruitment of members of minority groups in the profession and to their functioning as public intellectuals. The division into familial groups, the fights for security and success, and the weakness of the federal organization of the American Philosophical Association all contribute to these barriers. The second is that sociology has a place in philosophy, even though it should not be confused with it. This means that philosophers need to consider social phenomena.     

小学教师职业倦怠维度发展顺序探究——来自结构方程模型和交叉滞后网络分析模型的证据

教师职业倦怠的情感衰竭、去人性化和个人成就感降低3个维度相对独立但也存在相互影响, 对其发展关系进行研究, 有助于深入理解职业倦怠的发展过程, 尽早识别倦怠症状。本研究对3837名小学教师进行追踪测试, 测试间隔为3年, 采用结构方程模型和交叉滞后网络分析模型进行分析, 结果发现小学教师职业倦怠维度最优发展模型为“T1的情感衰竭和个人成就感降低分别预测T2的情感衰竭和个人成就感降低, T1的去人性化预测T2的去人性化和个人成就感降低”, 且最优发展模型具有性别间的一致性和教龄段之间的一致性。这一结果支持并强调了去人性化在小学教师职业倦怠发展中的重要作用, 对识别教师职业倦怠早期症状并采取相应措施有效阻断教师职业倦怠的进一步发展具有一定的理论和现实意义。     

压力性生活事件与青少年自尊：被动性社交网站使用和人生意义感的中介作用

采用青少年生活事件量表、被动性社交网站使用量表、生命意义感量表以及自尊量表对605名青少年施测,旨在探讨压力性生活事件对自尊的效应以及被动性社交网站使用和人生意义感的中介作用。结果发现：被动性社交网站使用和拥有人生意义感在压力性生活事件与自尊之间起中介作用,压力性生活事件分别通过被动性社交网站使用、拥有人生意义感的中介作用和被动性社交网站使用与拥有人生意义感的序列中介作用对自尊产生效应。     

失眠患者静息态脑网络的改变：网络内与网络间的功能连接异常

失眠已成为现代人群中的一种高发健康问题。静息态功能磁共振以其数据采集便利性和无创性, 成为失眠研究的主要成像手段之一。基于近年来静息态功能磁共振的发现, 失眠患者存在前额叶、颞叶、前扣带回、脑岛等认知-情绪神经环路的异常。大尺度脑网络是涵盖多个脑区、功能相对单一的大脑结构。失眠患者存在默认网络、突显网络、认知控制网络和负性情绪网络内部活动与连接异常, 而且呈现出以默认网络为核心, 包含认知控制网络、突显网络、负性情绪网络的网络间连接异常模式。此外, 结合症状、治疗和大尺度脑网络的视角, 可为失眠的“精准治疗”提供神经理论依据。未来研究可结合大数据和多模态分析技术, 验证静息态功能磁共振已有发现。而失眠的纵向追踪和队列研究会有利于进一步阐释失眠的神经机制。     

From Publics to Practitioners: Invention Power and Open Technoscience

Abstract

In technoscientific conditions what counts as knowledge creation is not primarily the individual experimental achievement that gives coherence to scientific practice and separates science from its publics; rather, it is a form of dispersed experimentation in more than human worlds: distributed invention power. Distributed invention power is organised and regulated through the pervasive securitisation of technoscience: surveillance and control of technoscientific fields as well as financialisation of its activities and research outputs. The securitisation of science reorders the traditional split between the public sphere, the private sector and the commons. The folding of each one of these spheres into the other underlies a constant, often antagonistic, oscillation between big science and open science. What is constitutive of the diverse movements that sustain open technoscience is not that they challenge technoscience as such but that they experiment with technoscience to create alternative forms of life.     

Job Analysis of United States Air Force Military Training Instructor Duty: Identification of Screening Criteria for Instructor Candidate Suitability

Initial military training-instructor duty places noncommissioned officers (NCOs) in a critical position of trust to safely, effectively train and transition recruits into military service. In this context, ineffective or inappropriate behavior by instructors has been shown to impact trainee mental health, unit cohesion, and integration ( Foran &; Adler, 2013 Foran, H. M., &; Adler, A. B. (2013). Trainee perceptions of drill sergeant qualities during basic combat training. Military Psychology, 25, 577–587. 10.1037/mil0000023[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Abuse of power, specifically exploitative and criminally and sexually abusive behavior by even a small number of instructors, as occurred in United States Air Force (USAF) basic military training (BMT) between 2010 and 2012, may result in a broad loss of public trust. Assessment of suitability for these duties is not consistently pursued across military services, with scant empirical work to best target what is necessary for safe, effective service as a BMT instructor. This article describes 3 job-analytic studies conducted to identify criteria for screening NCOs for USAF military training-instructor duty, as well as planned methods for evaluation.     

Global basic structure and institutions: The WTO as a practical example

In this article, I discuss the location of the sources of global poverty and injustice. I take it as granted that the members of the globally lowest income group live in unacceptable conditions and suffer from injustice. Yet the source of this injustice is a debatable question. Often the existing global institutions are seen as major causes behind this injustice. By taking the World Trade Organization (WTO) negotiations as a practical example, I aim to show that blaming the institutions as such can lead to misguided conclusions. The WTO, in fact, is quite just if one merely analyses its institutional structure. I argue that the major source of injustice are rather the prevailing power structures and the conduct of individual governments within this institutional framework, in other words the metaprocedural unfairness in the trade negotiations. I further argue that applications of Rawlsian theory of justice tend to be misleading at the global institutional level, as they focus disproportionately on the institutional structure, and tend to underestimate the relevance of the conduct of governments and the existing power structures, which allow powerful countries to use the institutional framework unjustly in their favour.     

Intelligence and Extraversion in the neural evaluation of delayed rewards

Temporal discounting (TD), the preference for earlier, smaller rewards over delayed, larger rewards, is a pervasive phenomenon that covaries with Big Five personality traits and Intelligence (IQ). This study provides novel insight by identifying correlates for IQ and Extraversion in the neural representation of TD preferences. An intertemporal choice task was employed, where offers were sequentially presented, distinguishing between one evaluation phase (first offer is presented) and one comparison phase (second offer is presented and values are compared). IQ correlated with responses of caudate nucleus to the subjective values of the offers, suggesting a role of cognitive abilities in modulating reward responses. Extraversion correlated with the strength of functional connectivity of a reward evaluation network centered on ventromedial prefrontal cortex.     

Testing equality of correlated proportions with incomplete data on both responses

Two test statistics are proposed for testing the equality of two correlated proportions when some observations are missing on both responses. The performance of these tests in terms of size and power is compared with other tests by means of Monte Carlo simulations. The proposed tests are easily computed and compare favorably with other tests.
