The educational boundary1

In this contribution, the authors defi ne and discuss the educational boundary in analytic training, which they believe is an often neglected and useful concept in psychoanalytic education. The framework on which their discussion rests includes the recent attention of psychoanalysts to issues of boundaries and ethics. Their understanding of how clinical work affects the mind of the analyst educator, as well as the ways the personalities of various analysts affect their dealings with faculty peers and students, are the other cornerstones of their discussion. The authors contend that many of the institutional problems encountered in the training of analysts can be better understood when viewed through the prism of the educational boundary. They present examples which illustrate several of the ways psychoanalytic educators complicate the training experience of candidates, offer specifi c explanations as to why analysts struggle as they try to manage their educational interventions, and indicate in a discussion of potential remedies that those behaviors might be avoided if the educational boundary is in focus. They also provide an example of how the educational boundary can be more effectively managed.     

医学伦理学不可忽视的课题：利益伦理

当今是一个以利益为轴心的时代。利益伦理学是医学伦理学不可忽视的课题。将病人利益置于首位应当是现代医学伦理学的首要原则。欲望是无穷的,利益是有限的。任何利益都有自己的边界和限度。我们必须设置利益的道德界限,以回答当前医学伦理学面临的种种现实课题。     

3D shape and orientation of nanoscale Pb inclusions at grain boundaries in Al observed by TEM and STEM tomography

We have combined high-angle annular dark field/scanning transmission electron microscopy (HAADF-STEM) tomography with bright field (BF)-TEM tomography to characterize small inclusions of Pb at a grain boundary in Al. It was found that the shape of the grain boundary inclusions is more complex than previously thought. By using moiré fringes observed at some orientations of the specimen in a BF-TEM tomographic tilt series, we were able to determine the orientation of each grain, the axis and angle of misorientation of the grain boundary, and the facet planes of the grain boundary inclusions. The 3D shape of the inclusions was determined by merging this information with the HAADF-STEM tomography.     

Chile's Environmental Assessments: Contested Knowledge in an Emerging Democracy

Abstract

In 1990, Chile transitioned to democracy after 17 years of military rule. The new democracy built the country's first environmental institutions and began efforts to revitalize science, among them attempts to connect scientific expertise to public decision-making. Just over a decade into these efforts, conflicts over the environmental impacts of large industrial projects began to multiply. These environmental conflicts were often also credibility contests, where the authority of science to speak to public issues was contested. Two such conflicts, a gold mine called Pascua Lama and a hydroelectric project called HidroAysén, enrolled several scientific teams, yet in each case the state made its final decision on each project autonomously from science. Though some scientists became central participants in each conflict, carving out for themselves access to needed resources that they used to practice ever-narrower forms of science, their credibility was called into question by many of their scientific colleagues. Chile's scientific community fractured over how to define credible science. Divisive and decisive issues included the source of funding, ethics, access to resources, and being local. Although some scientists and non-scientists used boundary work to try to affirm the authority of science, no stable map of scientific credibility resulted from these efforts. Chile's new democracy is more plural than its recent military dictatorship but still lacks adequate spaces in which to negotiate what counts as credible science. These experiences highlight the need to better understand how science fares through regime transitions and what it contributes to emerging democracies.     

Don't Let the Doorknob Hit You: A Relational-Intersubjective Exploration of Leaving and Remaining within the Therapeutic Frame

“Doorknob comments” is a concept that is not well represented in the professional literature. Through three case examples the author develops the theory that doorknob comments can fall within the internal structure of the session or outside of such a structure. In the former case, giving the internal element precedence by extending the session length to address the comments may be warranted. In the latter case, helping a client by scaffolding their ability to structure experience may require that the comment be processed at a later session. In either case, the ability to structure experience, which is the process of elaborating meaning, is an important aspect of treatment.     

The role of prediction in mental processing: A process approach

Although prediction plays a prominent role in mental processing, we have only limited understanding of how the brain generates and employs predictions. This paper develops a theoretical framework in three steps. First I propose a process model that describes how predictions are produced and are linked to behavior. Subsequently I describe a generative mechanism, consisting of the selective amplification of neural dynamics in the context of boundary conditions. I hypothesize that this mechanism is active as a process engine in every mental process, and that therefore each mental process proceeds in two stages: (i) the formation of process boundary conditions; (ii) the bringing about of the process function by the operation – within the boundary conditions – of a relatively ‘blind’ generative process. Thirdly, from this hypothesis I derive a strategy for describing processes formally. The result is a multilevel framework that may also be useful for studying mental processes in general.     

Grain orientation effects on delamination during fatigue of a sensitized Al–Mg alloy

Fatigue crack growth experiments were conducted in humid air (RH~45%) at 25 °C on 29-mm-thick plate samples of an aluminium–magnesium (Al–Mg) 5083-H131 alloy in the long transverse (LT) direction. Samples were tested in both the as-received condition and after sensitization at 175 °C for 100 h. Delamination along some grain boundaries was observed in the short transverse plane after fatigue testing of the sensitized material, depending upon the level of ΔK and K_max. Orientation microscopy using electron backscattering diffraction and chemical analyses using transmission electron microscopy and energy dispersive spectroscopy of grain boundaries revealed that Mg segregation and the orientation of grains had key roles in the observed grain boundary delamination of the sensitized material.     

词边界信息对读者阅读歧义短语时眼跳策略的影响

采用Eye Link 2000眼动仪,选取60个歧义短语,要求大学生被试阅读包含有歧义短语的句子。句子的呈现设置了四种条件:正常无阴影、词间阴影、歧义阴影和字间阴影,以探讨词边界信息是否影响读者阅读歧义短语时的注视位置效应。结果发现:读者对歧义短语的首次注视位置在四种条件下基本一致;词边界信息影响读者对歧义短语的再注视概率。结果表明,词边界信息对歧义短语的影响主要体现在眼跳行动(即"where")的晚期阶段。     

When all COVID breaks loose: Examining determinants of working parents' job performance during a crisis

As governments mandated organization and school closures due to COVID-19, working parents involuntarily found themselves trying to balance both work and child educational responsibilities from home while still endeavoring to remain productive at work. As such, we integrate the crisis management literature with boundary theory and the work–home resources model to propose and test a process model to better understand how abrupt shifts to remote work and school closures impact working parents' job performance during a crisis. Using data collected across four time periods beginning at the time when most states had issued “safer at home” orders, we examine a serial mediation model and find, consistent with predictions, that early experiences of boundary violations and job insecurity impact work–family balance self-efficacy, which in turn drives future job performance by way of its effects on working parents' subjective well-being. Implications for theory and practice are discussed.     

词频与阅读方式对词跨行呈现效应的影响

通过使用眼动追踪技术,采用2（呈现条件：同行呈现、跨行呈现）×2（词频：高频、低频）×2（阅读方式：朗读、默读）的被试内实验设计,探讨了词频和阅读方式对词跨行呈现效应的影响。结果发现,呈现条件、词频和阅读方式的主效应显著,跨行呈现、低频和朗读的凝视时间和总注视时间更长、总注视次数更多;呈现条件之间在凝视时间上的差异,高频词大于低频词;呈现条件之间在凝视时间和总注视次数上的差异,朗读大于默读。结果表明,词跨行呈现干扰了阅读,且这种干扰作用受词频和阅读方式的影响。
