A Child Wanted by Two,Conceived by Several: Lesbian-Parent Families Negotiating Procreation with a Known Donor

This article presents procreation agreement negotiations and the role played by men taking part as known donors in the parental project of lesbian mothers in the province of Quebec, Canada. Thirty-six individuals were interviewed: 10 female couples, 11 donors, and 5 of the donors’ life partners. The results show that the donors’ contribution takes place within a deliberative process during which the adults involved discuss 5 elements, namely (a) the procreation method selected, (b) the issue of future donations, (c) the forms of address and the role of the donor in the life of the children issuing from his donations, (d) the possible involvement of the donor's loved ones in the life of the lesbian-parent family, and (e) responses to various scenarios that might arise in the future. The negotiation also addresses concerns that those involved might have regarding the children's needs, resulting in a complex web of interpersonal relationships. Our findings show that dialogue is the key unifying factor, ensuring that everyone is in agreement and that the donor's role with respect to the child is in line with the expectations of everyone involved.     

多媒体教学环境下的教师角色探讨

结合目前英语课堂较多采用多媒体组织教学的现状,讨论了MCALL（多媒体计算机辅助教学）的性质,提出多媒体辅助教学不是一种教学方法,而是一种教学模式。教师在多媒体课堂上的角色应随其采用的教学方法的不同而不同。以课堂观察和问卷调查为基础,结合对某些教学方法的分析,讨论了多媒体教学环境下如何更好地扮演教师角色,提高精读课的课堂教学效果。     

Sharing Motherhood: Maternal Jealousy Among Lesbian Co-Mothers

Previous research has not adequately addressed how gay and lesbian couples emotionally negotiate unequal biological ties to their children. Because each co-parent has the potential to be their child's biological parent and because same-sex couples highly value relationship equality, unequal biological ties to children may cause feelings of jealousy between co-parents. To counter this, increasing numbers of lesbian couples have been using in-vitro fertilization (IVF) to biologically co-mother, using the eggs of one partner and the womb of the other. While hardly common, this strategy can affect the emotional dynamics between the co-mothers and their children. This article explores how variables common to many lesbian-led families (including method of conception) may contribute to or protect against jealousy.

Presented data comes from an 18-month ethnographic study of 30 lesbian-led families with young children living in a major northeastern city. Ten couples adopted infants, 10 couples used assisted insemination (AI), and 10 couples used IVF to biologically co-mother. Lesbians' use of IVF to co-mother has not been previously studied. Methods included in-depth interviews, participant observation, and self-administered questionnaires.

Couples who adopted or used IVF reported less jealousy than couples who conceived using AI. Factors that correlate with the likelihood of experiencing maternal jealousy include both partners wanting to be a birth mother, perceptions of unequal biological ties to children, and infertility. Professionals serving lesbian co-mothers should be sensitive to the presence and absence of the above factors.

Testing of the Function Focused Environment Assessment and the Function Focused Policy Assessment in Assisted Living

This study tested two new instruments, the Function Focused Environment Assessment (FF-EA) and the Function Focused Policy Assessment (FF-PA). The measures were developed for clinical evaluation of assisted living (AL) settings to help optimize function and physical activity among residents. In total, 106 AL settings and 242 residents were included. There was evidence of item reliability (0.92) and interrater reliability (kappa =0.40, p = .015; agreement 85%) of FF-EA and item reliability (0.89) and interrater reliability (kappa =0.48, p = .001, agreement 82%) of the FF-PA, and support for validity of both measures based on INFIT and OUTFIT statistics and hypothesis testing.
