forms of testing will empower these populations, and other multilingual populations, to change the way they perceive their language abilities. A significant step in the right direction would be to start classifying multilingual learners correctly in testing and to stop comparing them to monolinguals or bilinguals. Multilingual Testing and Assessment is essential to the expansion of the field of language testing and assessment. The invaluable information provided in this book can help make the testing industry more aware of the heterogeneity of multilingual learners. This awareness can lead to an increase in the visibility of assessments written in multiple languages. This book also contributes to the normalization of language mixing and code-switching and conveys the powerful message that mixed forms of testing should be allowed, given that they are an authentic representation of the way multilinguals use language in everyday communication. Multilingual learners are a representation of society’s diversity. Therefore, testing and assessment must be designed to align to meet the needs of all language learners.
各种形式的测试将使这些人群和其他多语言人群能够改变他们对语言能力的感知方式。朝着正确方向迈出的重要一步是在测试中开始正确地对多语言学习者进行分类,并停止将他们与单语或双语者进行比较。多语言测试和评估对于拓展语言测试和评价领域至关重要。本书中提供的宝贵信息可以帮助测试行业更多地意识到多语言学习者的异质性。这种认识可以提高以多种语言编写的评估的可见性。这本书也有助于语言混合和代码转换的规范化,并传达了一个强有力的信息,即应该允许混合形式的测试,因为它们真实地代表了多语言在日常交流中使用语言的方式。多语言学习者是社会多样性的代表。因此,测试和评估的设计必须符合所有语言学习者的需求。

The book tackles two interwoven issues in international bi/multilingual education and research. It proposes connecting an e ff ective curriculum design method to an engaging teaching pedagogy in order to improve the biliteracy of language students. To achieve this, the two authors have brought together the two methods – a curriculum design method for disciplinary knowledge using Elizabeth Rata ’ s Curriculum Design Coherence (CDC) Model and TransAcquisition Pedagogy (TAP), the method developed by Tauwehe Sophie Tamati for teachers to use students ’ bi/multi languages in teaching academic subjects. Both methods were originally developed for use in New Zealand – TAP in M ā ori culture and language schools known as kura kaupapa M ā ori (Tamati 2016), and the CDC Model for schools in the Knowledge-Rich School Project (Rata 2021). However, they are methods that can be used with any students who have two or more languages, including those with indigenous and minority languages. The
本书探讨了国际双/多语教育和研究中两个相互交织的问题。提出将有效的课程设计方法与参与式教学方法相结合,以提高语言学生的双语能力。为了实现这一目标,两位作者将两种方法结合在一起——一种是使用伊丽莎白·拉塔(Elizabeth Rata)的课程设计一致性(CDC)模型的学科知识课程设计方法,另一种是Tauwehe Sophie Tamati开发的跨习得教学法(TAP),该方法旨在让教师在教学中使用学生的双/多语言。这两种方法最初都是为新西兰开发的- TAP在被称为kura kaupapa M ā ori的M ā ori文化和语言学校(Tamati 2016),以及CDC在知识丰富学校项目中的学校模型(Rata 2021)。然而,这些方法可以用于任何掌握两种或两种以上语言的学生,包括那些掌握土著语言和少数民族语言的学生。的

‘offered an analysis of a Polish piece of poetry or a commentary on his favorite heritage author’ (276). Such suggestions are valuable for all teachers of immigrant or multilingual youth. The Multilingual Adolescent Experience is a unique, critical body of work that places immigrant adolescents at the forefront of the discussion of their own needs. By interviewing students and their families about language socialization practices as they naturally occur in these students’ real lives, Machowska-Kosciak offers an illuminating and engaging view of the assets multilingual, multicultural youth could bring to the classroom if they were only given the opportunity. Adolescence, Machowska-Kosciak explains, is an era of seeking belonging ‘to something bigger’ (99) than family. The Multilingual Adolescent Experience teaches readers that immigrant teenagers may feel as though they have to choose one language, one culture to belong to. It is our responsibility, as educators, to teach them that it is possible to choose both.
“对一首波兰诗进行了分析,或者对他最喜欢的传统作家进行了评论”(276)。这些建议对所有教移民或多语青年的教师都很有价值。《多语言青少年的经历》是一本独特而重要的著作,将移民青少年置于讨论其自身需求的最前沿。Machowska-Kosciak通过采访学生和他们的家庭,了解他们在现实生活中自然发生的语言社会化实践,提供了一个具有启发性和引人入胜的观点,即如果有机会,多语言、多元文化的年轻人可以为课堂带来的资产。Machowska-Kosciak解释说,青春期是一个寻求比家庭更大的归属感的时代。《多语言青少年的经历》告诉读者,移民青少年可能会觉得他们必须选择一种语言,一种文化。作为教育者,我们有责任告诉他们两者都可以选择。

Introduction: Alternative protein sources have recently been attracting growing interest as potential components of livestock nutrition. This study evaluated the effect on broiler health of replacing the soybean protein component of poultry feed with processed insect protein from farmed Hermetia illucens (HI) larvae.

Material and methods: A total of 384 male broiler chicks were divided into four diet groups (eight pens/treatment and 12 birds/pen) and reared to the 42nd day of life (dol). Each treatment group received a starter diet until the 14th dol, then a grower diet until the 35th and finally a finisher diet until the 42nd. The soybean meal in standard diets was replaced with full-fat HI larvae meal in the following amounts: 0% for the control group HI-0, 50% for group HI-50, 75% for group HI-75, and 100% for group HI-100. At 1 dol, chicks were vaccinated against Marek's disease, coccidiosis, Newcastle disease and infectious bronchitis and at 7 dol against avian metapneumovirus infections using live-attenuated vaccines. Blood and spleen samples were collected at three and six weeks of age and analysed using ELISA, flow cytometry, haematology and biochemistry.

Results: On the 42nd dol, as the content of larvae meal in the chickens' diets increased, the birds' body weights decreased significantly. The substitution of the protein source had no effect on the haematological markers. In chicks that received larvae meal, there was a decrease in creatine kinase activity and phosphorus levels and an increase in calcium and uric acid levels in serum. Raising the proportion of full-fat HI larvae meal in the diet raised the percentage of T CD3+CD8a+ cells and lowered that of T CD3+CD4+ cells in both sample types. Chickens fed larvae meal had significantly lower post-vaccination anti-infectious bronchitis virus antibody titres.

Conclusion: The poorer production results and impaired health in experimental birds may indicate lower than 50% protein substitution with full-fat HI larvae meal to be optimal.

导言:作为家畜营养的潜在成分,替代蛋白质来源最近引起了越来越多的关注。本研究评估了用养殖的白头翁(HI)幼虫加工的昆虫蛋白替代家禽饲料中的大豆蛋白成分对肉鸡健康的影响:将 384 只雄性肉用仔鸡分为 4 个日粮组(8 栏/处理组,12 只/栏),饲养至出生后第 42 天(dol)。每个处理组在第 14 dol 前使用开食性日粮,然后在第 35 dol 前使用生长型日粮,最后在第 42 dol 前使用育成型日粮。标准日粮中的大豆粉用全脂 HI 幼虫粉代替,用量如下:对照组 HI-0 为 0%,HI-50 组为 50%,HI-75 组为 75%,HI-100 组为 100%。雏鸡 1 dol 时接种马立克氏病、球虫病、新城疫和传染性支气管炎疫苗,7 dol 时接种禽偏肺病毒减毒活疫苗。在 3 周龄和 6 周龄时采集血液和脾脏样本,并使用 ELISA、流式细胞术、血液学和生物化学方法进行分析:第 42 dol,随着鸡日粮中幼虫粉含量的增加,鸡的体重明显下降。蛋白质来源的替代对血液指标没有影响。摄入幼虫粉的雏鸡血清中肌酸激酶活性和磷含量下降,钙和尿酸含量上升。提高日粮中全脂 HI 幼虫粉的比例可提高两种样本中 T CD3+CD8a+ 细胞的比例,降低 T CD3+CD4+ 细胞的比例。饲喂幼虫粉的鸡在接种后的抗传染性支气管炎病毒抗体滴度明显较低:实验鸡的生产成绩较差,健康状况受损,这表明用全脂 HI 幼虫粉替代低于 50%的蛋白质是最佳的。
