NaCl胁迫对不同番茄品种幼苗及果实的影响

研究了NaCl胁迫对5个不同番茄品种的幼苗生长、果实可溶性糖含量及产量的影响.结果表明,盐胁迫抑制了番茄幼苗植株的生长,降低了幼苗的单株鲜重,减少了果实产量,但可以提高果实可溶性糖含量.同一盐胁迫条件下,不同番茄品种性状存在显著差异.

Mothers’ and Fathers’ Roles in Caring for an Adult Child with an Intellectual Disability

To date, there have been few studies of mothers’ and fathers’ roles in caring for their adult children with intellectual disabilities. The present study investigated the care-giving roles of mother and father couples caring for their adult offspring with an intellectual disability, their psychological health, and the demands and satisfaction of their care-giving roles. Twelve Anglo-Australian middle-aged mother and father couples with an adult child with intellectual disability (mean age?=?24 years) participated in semi-structured interviews about their care-giving roles and completed a series of questionnaires pertaining to care-giving difficulties and satisfaction, hassles and uplifts, and general health. Findings indicated that an extremely high proportion of both mothers and fathers were in the clinical range for social dysfunction, anxiety/insomnia, and somatic complaints, although levels of depression were relatively low. The present study found that mothers undertake more daily care-giving tasks than fathers, but that the range of tasks is similar. Mothers also reported significantly more care-giving difficulties and satisfaction than fathers. Associations between measures differed somewhat for the two parent groups, indicating the need for further exploration of both mothers’ and fathers’ experiences.     

Pain, suffering, and trauma in labor and prevention of subsequent posttraumatic stress disorder

In this column, Kimmelin Hull, community manager of Science & Sensibility, Lamaze International's research blog, reprints and discusses a recent blog post series by acclaimed writer, lecturer, doula, and normal birth advocate Penny Simkin. Examined here is the fruitful dialog that ensued-including testimonies from blog readers about their own experiences with traumatic birth and subsequent posttraumatic stress disorder. Hull further highlights the impact traumatic birth has not only on the birthing woman but also on the labor team-including doulas and childbirth educators-and the implied need for debriefing processes for birth workers. Succinct tools for assessing a laboring woman's experience of pain versus suffering are offered by Simkin, along with Hull's added suggestions for application during the labor and birth process.

中学教师职业压力调查分析

教育学、心理学、工效学、医学等多学科的研究均发现职业压力已成为一种严重影响人的身心健康和工作、生活质量的社会流行病。教师，尤其是中学教师，由于其职业的特殊性，压力过大或过于持久，不仅会严重损害他们的身心健康，还会影响到他们的学生——青少年的健康成长。这里运用自编的中学教师职业压力问卷，对428名城市普通中学教师的职业压力现状进行了调查研究和分析。

Word stress production in three‐year‐old children at risk of dyslexia

We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.
