中国古代的水煮方便食品:棋子面与挂面

棋子面最早出现于《齐民要术》,是一种状如棋子、蒸熟以备不时水煮食用的方便食品。唐宋元明各代多作为军食,其烹熟方式也衍生出炒、油煎等,后世又作为幼儿方便食品。近代的"棋子面"则多了一种擀切为菱形的面片。"挂面"一词始出《饮膳正要》,但在唐代敦煌文献中即有"须面"称谓,元代文献也称之为"索面"。是一种水煮方便条状粉食。

Autistic young people’s experiences of transitioning to adulthood following the Children and Families Act 2014

Changes to special educational needs and disability (SEND) legislation in England were implemented in 2014. Here, we evaluate the impact of these changes from the perspective of 80 autistic young people aged 16–25 years. Using an online survey and/or interviews, we examined young people’s views on three key principles of the SEND reforms: the help and support provided to them; whether they were given a say in the choices and support that they were offered; and their satisfaction with their educational journeys and outcomes. The results paint a mixed picture. Our sample of young people reported varied experiences regarding the help and support they received, and how much of a say they had regarding the choices and support available to them. The types of schooling they accessed played a role here: young people in mainstream schools highlighted particular challenges in accessing appropriate support, while many young people in special schools said they felt well supported. Parental advocacy was crucial for all young people, as was having key ‘champions’ in the form of teachers who really knew them well. The need for the development of general life and self-advocacy skills was apparent, however, especially in preparing the young people for life after school. Encouragingly, most of our participants were generally happy with their current situation, despite identifying several areas for further improvement. Overall, the results highlight the importance of listening to—and learning from—autistic young people, throughout their educational journeys and especially as they transition to adulthood.     

Responding to racism at school: Ethnic-racial socialization and the academic engagement of Black and Latinx youth

Guided by the Theory of Racial Socialization in Action (TRSA; Smith-Bynum in press), this study examined observed caregiver-provided ethnic-racial socialization in response to a school-based discriminatory dilemma. Forty-five Black and 36 Latinx caregivers (88% mothers) with low-income and their children (M_age = 11.09, SD = 0.29; 46.3% female) participated in Dallas, Texas from 2018 to 2019. Dyads responded to a hypothetical scenario in which a school counselor makes a discriminatory comment to the child. Results of a factor mixture analysis suggested that caregivers engaged in the dialogue using one of four approaches: Low-engaged, Legacy, Racial Literacy, or High-engaged. Profiles were found to differ significantly by the race/ethnicity and language of caregivers and were associated with youth’s concurrent behavioral engagement (R² = .04).     

Teaching anti-racist counseling theories: Black liberation narrative therapy

Counseling theories created by White theorists have traditionally failed to consider the religious or spiritual experiences of Black clients. Integration of Black liberation theology and narrative therapy provides a novel approach to support counseling trainees in meeting the needs of Black clients. Decolonizing therapeutic strategies are presented along with counselor educator recommendations.     

How to conduct External Quality Assessment Schemes for the pre-analytical phase?

In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizations operating in most countries. The aim of the paper is to present an overview of different types of EQA schemes for the pre-analytical phase, and give examples of some existing schemes. So far, very few EQA organizations have focused on the pre-analytical phase, and most EQA organizations do not offer pre-analytical EQA schemes (EQAS). It is more difficult to perform and standardize pre-analytical EQAS and also, accreditation bodies do not ask the laboratories for results from such schemes. However, some ongoing EQA programs for the pre-analytical phase do exist, and some examples are given in this paper. The methods used can be divided into three different types; collecting information about pre-analytical laboratory procedures, circulating real samples to collect information about interferences that might affect the measurement procedure, or register actual laboratory errors and relate these to quality indicators. These three types have different focus and different challenges regarding implementation, and a combination of the three is probably necessary to be able to detect and monitor the wide range of errors occurring in the pre-analytical phase.     

Sub-nanomolar detection of thrombin activity on a microfluidic chip

Bioluminescence resonance energy transfer (BRET) is a form of Förster resonance energy transfer. BRET has been shown to support lower limits of detection than fluorescence resonance energy transfer (FRET) but, unlike FRET, has not been widely implemented on microfluidic devices for bioanalytical sensing. We recently reported a microscope-based microfluidic system for BRET-based biosensing, using a hybrid, high quantum-efficiency, form of BRET chemistry. This paper reports the first optical fiber-based system for BRET detection on a microfluidic chip, capable of quantifying photon emissions from the low quantum-efficiency BRET² system. We investigated the effects of varying core diameter and numerical aperture of optical fibers, as well as varying microfluidic channel design and measurement conditions. We optimized the set-up in order to maximize photon counts and minimize the response time. The optimized conditions supported measurement of thrombin activity, with a limit of detection of 20 pM, which is lower than the microscope-based system and more than 20 times lower than concentrations reported to occur in plasma clots.
