This chapter reviews the book Stepmother Russia, Foster Mother America: Identity Transitions in the New Odessa Jewish Commune, Odessa, Oregon, New York, 1881–1891 (2014), by Theodore H. Friedgut, together with Israel Mandelkern, Recollections of a Communist (edited and annotated by Theodore H. Friedgut). Stepmother Russia, Foster Mother America is a two-in-one volume that explores an obscure episode in the history of the Jews in the late nineteenth century while at the same time connecting much of its content to the author’s own life experience as a son of western Canada’s Jewish farming colonies and, later, as an ideologically driven halutz on an Israeli kibbutz. Stepmother Russia, Foster Mother America retells one branch of the mostly forgotten history of the Am Olam agricultural movement and brings a new layer into the discussion of global Jewish agrarianism, while Recollections of a Communist offers an edited and annotated version of a memoir written by Mandelkern.

A growing body of studies is showing that offspring telomere length (TL) can be influenced by the age of their parents. Such a relationship might be explained by variation in TL at conception (gamete effect) and/or by alteration of early growth conditions in species providing parental care. In a long-lived bird with bi-parental care, the Alpine swift ( Apus melba ), we exchanged an uneven number of 2 to 4-day-old nestlings between pairs as part of a brood size manipulation. Nestling TL was measured at 50 days after hatching, which allowed investigation of the influence of the age of both their biological and foster parents on offspring TL, after controlling for the manipulation. Nestling TL was negatively related to the age of their biological father and foster mother. Nestling TL did not differ between enlarged and reduced broods. These findings suggest that offspring from older males were fertilized by gametes with shorter telomeres, presumably due to a greater cell division history or a longer accumulation of damage, and that older females may have provided poorer parental care to their offspring.

Abstract. In the neonatal male rat, a rapid and transient increase in serum testosterone occurs about 2 h after birth. This post-partum testosterone surge (PPTS) has been implicated in the masculinization and defeminization of the central nervous system. The present study shows that environmental temperature can have a profound influence on the PPTS. Male rats were delivered from their mothers by caesarean section on day 22 of gestation. Immediately thereafter, neonatal males were placed at an ambient temperature of either 18, 21, 24 or 30°C. With 2 h of exposure, the body temperature was in close correspondence with the ambient temperature. The PPTS was clearly abolished in the pups exposed for 2 h at either 18 or 21°C. The effect of temperature was reversible: by placing pups at either 18 or 21°C for 2 h after delivery, and then rewarming by placing them with a foster mother, the PPTS was delayed until 4 h after birth, i.e. 2 h after the beginning of rewarming. Thus, environmental cooling appears to retard the development of neural and/or endocrine systems mediating the PPTS. Aberrant maternal care which would produce substantial cooling of the male pups would be expected to affect the PPTS, which in turn might affect the sexuality of male progeny.

Parthenogenetic Embryos

Porcine nuclear transfer (NT) is an inefficient process and it is necessary to use as many as 120 NT embryos for each foster mother to obtain small litters of live piglets. In these experiments, we evaluated the effects of culture atmosphere and medium on the development of NT embryos by monitoring blastocyst rate and cell number of Day 6 blastocysts. Age matched IVF and parthenogenetic embryos were also evaluated for comparison. For all experiments a pool of oocytes was aspirated from ovaries collected in a local abattoir. Following aspiration, oocytes were allowed to mature for 40 h in North Carolina State University (NCSU)-37 medium (supplemented with cAMP and hCG/eCG for the first 22 h). After removal of the cumulus cells, denuded oocytes with polar bodies were selected for NT, enucleated, fused with fetal fibroblasts, and sequentially activated electrically and chemically by 3 h of treatment with 6-dimethylaminopurine (6-DMAP). A second group of oocytes from the same denuded pool were maintained in TL-HEPES medium and activated in parallel with the NT group to produce parthenogenetic embryos. A third group was fertilized with frozen-thawed epididymal semen and co-cultured for ∼12 h to give IVF embryos. All three treatment groups were subdivided into a control subgroup and an experimental subgroup. In the first experiment, we compared the effects of atmosphere (20% vs. 5% oxygen) on in vitro embryonic development in NCSU-23 medium. In the second experiment, we used only the 5% oxygen concentration and compared different culture media. One subgroup was maintained in standard NCSU-23 medium and the second subgroup was cultured in a two-step system for the first 58 h in modified NCSU-23 (without glucose but supplemented with 2.0 mM lactate and 0.2 mM pyruvate), followed by addition of glucose to give a final concentration of 5.55 mM. Data were statistically analyzed by analysis of variance and chi square test. Blastocyst rate and mean cell number in all three embryo groups were improved under 5% oxygen. The most dramatic effect was observed in the NT group, in which the blastocyst rate increased significantly (P < 0.001) from 6.7% ± 5.9 (n = 279) to 19.6% ± 8.9 (n = 250) and mean cell number increased from 17.7 ± 12.1 to 25.8 ± 10.3 cells per blastocyst. With 5% oxygen there was also an increase of blastocyst rates and mean cell numbers in both IVF and parthenogenetic groups. In the second experiment, blastocyst rate for NT embryos increased significantly (P < 0.05) from 21.8% ± 7.6 (n = 242) in conventional NCSU-23 to 31.5% ± 11.0 (n = 271) in the modified system whereas there was almost no difference in the mean cell number of both groups (29.2 ± 4.3 vs. 31.5 ± 5.3). In the groups of IVF and parthenogenetic embryos no difference was found. These results indicate that both the reduced oxygen and the modified culture medium are important for pre-implantation development of porcine nuclear transfer embryos.

This chapter examines the ambiguity of the foster parent role in the post-World War II period, looking particularly at analogies to other kinds of parenting. It explores efforts by child welfare professionals to reconcile their ambivalent feelings about foster parents through the creation and promotion of national standards for foster care and foster parenting. The chapter looks closely at professional writings about the foster mother role and the reasons why foster fathers received so little attention. It also examines the ways in which foster parents resisted their proscribed role, notably through attempting to adopt children in their care.

This chapter provides a female-centric lens on kinship relations in the Qur’an. It considers Qur’anic depictions of mothers, grandmothers, daughters, and sisters. In addition to many general descriptions of childbearing, childrearing, and parent–child relationships, the Qur’an includes figures that epitomize nearly all of the different constellations of parent–child relationships, including foster mother figures and their sons (Joseph and Moses) and a father figure with his foster daughter (Mary). The Qur’an consistently depicts daughters and sisters as morally upright, while by contrast, it contains multiple narratives of sons and boys who are morally corrupt. Qur’anic narratives depict several female figures leveraging their kinship networks to the benefit of vulnerable male figures in distress. The chapter provides detailed intra-textual analysis of concepts related to female reproduction, including the womb and motherhood.
