Maximum Product,Even Less Process: Increasing Efficiencies in Archival Processing Using ArchivesSpace

As the archival profession has adapted to new challenges and adopted modern practices like More Product, Less Process, the University of Minnesota has embraced these changes. Even so, implementing new practices can take time and effort. With the adoption of ArchivesSpace in 2016, the University found itself being fast-tracked to even more efficient methods for establishing physical and intellectual control over collections. This article will examine the case studies of two large collections that were in the midst of being processed when ArchivesSpace was implemented at the University of Minnesota. How did the switch to ArchivesSpace impact the processing of these collections, and how will these experiences impact the future of archival processing at the University?     

《齐民要术》中的粥食浅议

粥为人们所常食,一般以植物种子(果实)为主要原料,与水同煮至半流质状,易于消化吸收。千百年来,粥在中华民族的繁衍和生存中起到举足轻重的作用。《齐民要术》中特设一章,详细介绍了一种"杏酪粥"的来龙去脉及做法,反映出当时粥食在人们生活中应有的地位。     

认知心理学两种研究范式的争论与反思

符号加工和联结主义是认知心理学的两种研究范式,二者在认知心理学内部产生了一系列的争论。在一般 认知问题上的争论主要表现在语义理解、心理表征以及一些具体的认知问题上;在方法论问题上的区别主要表现在是 结构模拟、黑箱方法、还原主义还是结构与功能模拟、灰箱方法和整体主义上。两种范式争论的本质问题是究竟哪种 范式更加符合认知过程的本质。联结主义范式似有取代符号加工范式的趋势,但它也不能完全揭示人类的高级认知功 能,因此出现了行为主义的进化论研究范式。

Children’s emotional and behavioral responses to peer provocation and early school adjustment

ABSTRACT

Even very young children think about their own and others’ behavior, including emotions. Such cognitions and emotions about the self and others convey information that is crucial to social interactions and relationships. The current study based on an integrated model of emotion processes and cognition in social information processing (SIP) aimed to explore students’ emotional and behavioral responses in SIP choices, and their association with teacher-reported early school adjustment. Two-hundred and thirty pre-school and first-grade primary school students were interviewed using the Challenging Situations Task (CST). CST assessed students’ emotional and behavioral responses to 12 unambiguous hypothetical peer provocation situations. Children’s preschool and first-grade primary teachers rated children’s early school adjustment with the Social Competence and Behavior Evaluation (SCBE-30) measure. The results revealed that children chose mainly sad and angry emotions and socially competent and passive behaviors. We found a relationship both between sad emotions and socially competent behavior choices, and between angry emotion and aggressive behavior choices. Sad emotions and aggressive behavior choices were the main predictors of school adjustment. Children’s responses to peer provocation situations varied depending on how the children interpreted the situations. The results address the importance of children’s SIP and school adjustment.

Observations on the temporal correlates of reading failure

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.     

椭球加工的两种数控编程方法及其比较

结合一个具有椭半球轮廓的工件，分别用用户宏程序编程和自动编程两种方法进行编程，并对两个数控程序进行了仿真加工和比较，最终得出两种编程方法各自的优缺点及其适用范围，为合理选择零件的数控编程方法提供参考。
