伍德对胡萨米:马克思和正义问题之争

伍德与胡萨米关于马克思是否批判资本主义为不正义之争是一场富有启发性的论争。本文从三个方面对这场论争做了简要的述评：(1)马克思批判资本主义社会是否基于某种正义观?(2)马克思是否认为资本主义剥削是不正义的?(3)在马克思的视野中,共产主义是否是一个正义社会?     

Neurocognitive mechanisms underlying the experience of flow

Recent theoretical and empirical work in cognitive science and neuroscience is brought into contact with the concept of the flow experience. After a brief exposition of brain function, the explicit-implicit distinction is applied to the effortless information processing that is so characteristic of the flow state. The explicit system is associated with the higher cognitive functions of the frontal lobe and medial temporal lobe structures and has evolved to increase cognitive flexibility. In contrast, the implicit system is associated with the skill-based knowledge supported primarily by the basal ganglia and has the advantage of being more efficient. From the analysis of this flexibility/efficiency trade-off emerges a thesis that identifies the flow state as a period during which a highly practiced skill that is represented in the implicit system's knowledge base is implemented without interference from the explicit system. It is proposed that a necessary prerequisite to the experience of flow is a state of transient hypofrontality that enables the temporary suppression of the analytical and meta-conscious capacities of the explicit system. Examining sensory-motor integration skills that seem to typify flow such as athletic performance, writing, and free-jazz improvisation, the new framework clarifies how this concept relates to creativity and opens new avenues of research.     

Memory systems of the brain: a brief history and current perspective

The idea that memory is composed of distinct systems has a long history but became a topic of experimental inquiry only after the middle of the 20th century. Beginning about 1980, evidence from normal subjects, amnesic patients, and experimental animals converged on the view that a fundamental distinction could be drawn between a kind of memory that is accessible to conscious recollection and another kind that is not. Subsequent work shifted thinking beyond dichotomies to a view, grounded in biology, that memory is composed of multiple separate systems supported, for example, by the hippocampus and related structures, the amygdala, the neostriatum, and the cerebellum. This article traces the development of these ideas and provides a current perspective on how these brain systems operate to support behavior.     

What counts as knowing? The development of conceptual and procedural knowledge of counting from kindergarten through Grade 2

The development of conceptual and procedural knowledge about counting was explored for children in kindergarten, Grade 1, and Grade 2 (N = 255). Conceptual knowledge was assessed by asking children to make judgments about three types of counts modeled by an animated frog: standard (correct) left-to-right counts, incorrect counts, and unusual counts. On incorrect counts, the frog violated the word-object correspondence principle. On unusual counts, the frog violated a conventional but inessential feature of counting, for example, starting in the middle of the array of objects. Procedural knowledge was assessed using speed and accuracy in counting objects. The patterns of change for procedural knowledge and conceptual knowledge were different. Counting speed and accuracy (procedural knowledge) improved with grade. In contrast, there was a curvilinear relation between conceptual knowledge and grade that was further moderated by children's numeration skills (as measured by a standardized test); the most skilled children gradually increased their acceptance of unusual counts over grade, whereas the least skilled children decreased their acceptance of these counts. These results have implications for studying conceptual and procedural knowledge about mathematics.     

Motor sequence learning and reading ability: is poor reading associated with sequencing deficits?

Although it is widely assumed that children with learning disabilities have "sequencing problems," these have not been well specified. A non-verbal serial reaction time (SRT) paradigm was used to evaluate motor sequence learning in 422 children between ages 7 and 11 in relation to reading, cognitive ability level, and attention problems. The children demonstrated the response profile typically associated with motor sequence learning, but the component of the profile indicative of implicit sequence learning was not reliably associated with any of the predictors. Cognitive ability predicted overall response time; cognitive ability, reading, and attention problems each predicted overall accuracy. Explicit learning was predicted by cognitive ability, but not by reading or attention problems. Thus, we found no evidence that poor reading is preferentially associated with a domain general deficit in sequential learning.     

The Gospel according to civic engagement

The author of this passage suggests that hospitality is at the heart of both Christianity and politics. They draw on the writing of Martin Luther, who argues that Christians do not live in themselves but in Christ and their neighbor. This paper invites us to consider that Christian relationships should not be individualistic, as this removes them from the community and movement that Jesus established. Rather, Christians must act collectively to combat societal issues and oppression. By choosing to get involved civically, whether through elections, community organizing, or advocacy, individuals can choose to side with either self-interest or radical hospitality. The author suggests that choosing radical hospitality is the way to live in Christ and our neighbor, and to truly demonstrate authentic love for those around us. The author is reflecting on their decision to engage in local politics after witnessing civil unrest and racial injustices in their community. They highlight the importance of public witness as a prophetic act, grounded in faith and a desire for justice. The author draws on the teachings of Martin Luther and the tradition of the Black church as inspiration for their political engagement, which they see as a way to serve their neighbors and demonstrate their love and teachings. They also acknowledge the challenges and complexities of political leadership, especially in the face of corruption and unethical practices. Overall, the author's message is one of hope and a commitment to working towards a more equitable and hospitable community for all.     

On the evolution of adjudicated contests and the principle of invidious

Limited resources (e.g. jobs research grants, welfare, attention) are often allocated to those who desire them according to assessments of merit or deservingness made by presumably neutral judges. The resulting adjudicated contests are, in principle, more fair than other means of allocation: market economies, violence, privilege, kickbacks, etc. However, as adjudicated contests evolve they tend to attract an increasing number of qualified contestants. If resources do not expand to reward these contestants, additional tests of merit or deservingness are often invoked to make increasingly small contestant discriminations. These additional tests are shown to be breeding grounds of invidious selection vitiating the principle of fairness that characterizes the contests in which they are employed. The causes and consequences of invidious selection are discussed, as are some possibilities of their avoidance.     

The role of procedural memory in grammar and numeracy skills

The objective of this study was to examine the contribution of procedural memory to grammar and numeracy skills, which both involve the manipulation of abstract patterns. Seventy-six typically developing children between 5 and 7 years of age were assessed on grammar with a past tense production task and a sentence comprehension task, on numeracy with a counting task and a calculation task, and on procedural memory with a serial reaction time task. Moderate correlations were found between the measures of grammar and numeracy. Moreover, 4 hierarchical linear regressions indicated that procedural memory was associated with calculation but not with counting or grammar skills when age and working memory were taken into account. These novel findings suggest that procedural memory may have a role to play in the development of some numeracy skills. Several possible explanations for the absence of contribution to grammar are considered.     

PROPERTY OR PERSONS: ON A “PLAIN READING” OF THE UNITED STATES CONSTITUTION

The views of Frederick Douglass, Thurgood Marshall, and Clarence Thomas on how the United States Constitution should be read are examined. Thomas claims that his understanding of the Constitution aligns with Douglass. I conclude that Thomas misunderstands the strategy of Douglass and fails to appreciate the honesty of Marshall.     

Distributive justice in marriage: Equality or equity?

Experimental studies of distributive justice suggest that men prefer an equity rule for allocating rewards, whereas women prefer equality. These differences are likely to carry implications for distributive justice in the context of marriage. There is a popular view in Western societies that marriage should be regarded as a partnership of equals, and this is also an implicit assumption in microeconomic accounts of the family. However, inequality between spouses is still commonplace, with the husband more likely to have overall financial control and greater access to money for personal spending (PSM). This paper investigates the issue of sharing in marriage, with particular reference to PSM, using data from an in-depth interview study supplemented by some follow-up questionnaires. The participants were 13 women and nine of their partners, mainly ‘middle class’ and aged between 30 and 50. After classifying each couple's system of financial management, the paper focuses upon eight couples with a philosophy of sharing. The findings show that, despite attempts to equalize outcomes for both partners, a sense of ‘ownership’ associated with having earned the money seemed to render it more salient than other, non-financial contributions to the marriage. As a result, patterns of control and personal spending appeared to be based upon equity rather than equality.
