Exercising the Utmost Vigilance: The Catholic Campaign AgainstContraception in New Zealand During the 1930s*

The Catholic campaign against contraception in New Zealand during the 1930s is usually interpreted from the perspective of the promoters of birth control, who accused the church of exercising undue influence over the Labour government (1935–49). This paper argues that while Catholics were the most outspoken opponents of contraception, their opposition to the dissemination of birth control information and contraceptive devices was shared with other influential groups, notably the Protestant churches, the medical profession, journalists, and politicians. It was the combined strength of these conservative interests, not pressure from Catholics alone, which discouraged the Labour government from establishing birth control clinics. Catholics and many other New Zealanders feared that increased access to contraceptives would reduce the birth rate, leaving New Zealand vulnerable to non-British migration or even invasion. There was also widespread concern that the promotion of birth control would encourage sexual promiscuity. Since Catholics sought a compete ban on artificial contraception, however, they were unable to cooperate with non-Catholics who, accepting the restrained use of contraceptives, sought only to limit their availability. Catholic influence reinforced the efforts of other conservative interests but was not strong enough to secure legislation reflecting distinctively Catholic principles.     

A Test of Ideal Free Distribution Predictions Using Targeted Survey and Excavation on California’s Northern Channel Islands

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.     

Sclerochronological analysis of archaeological mollusc assemblages: methods,applications and future prospects

Accreting skeletal tissues found in bone, teeth, otoliths and molluscan shell act as sensitive recorders of local environmental and climatic conditions. Owing to their robust nature, ubiquity and abundance in the archaeological record as well as the potential for high-resolution data acquisition, the accreting skeletal tissues of archaeological molluscs are increasingly employed as palaeoenvironmental proxies. Researchers have chiefly utilised such proxies to extend instrumental records of environmental conditions through palaeoenvironmental reconstruction and explore the impact of environmental and climatic change on human populations. However, the use of environmental proxies from the archaeological record can be hampered by a number of methodological challenges including inadequate sampling strategies, appropriate calibration, the use of inappropriate proxies and the broad extrapolation of localised results. This paper reviews the use of molluscan shell from archaeological contexts as palaeoenvironmental proxies. We focus on the application of sclerochronology—a suite of high-resolution physical and geochemical data recovery methods widely used in conjunction with molluscan shell. This paper presents an overview of the potential of these techniques in approaching more nuanced understandings of human-environment interactions and how they can be more successfully incorporated into archaeological research.     

Hydrodynamic sorting in a coastal marine skeletal assemblage

In this paper I evaluate the effects of wave and tidal erosion on element‐specific measures of phenotypic variability. Previous research has found a high correlation between skeletal weight, shape, and density and the transport potential of an element exposed to hydrodynamic forces. However, no previous studies have attempted to address the issue of within‐element sorting based on selective removal of only the smallest members of a given element class. I evaluate this hypothesis using a human skeletal sample from Bird Island (8DI52) located in Dixie County, Florida. This sample comprises two components, an eroded sample that was exposed during severe storm and tidal activity, and an uneroded sample excavated from primary context. The measurement‐specific means for the subcomponents were compared using Student's t and Wilcoxon tests and variability differences were evaluated based on standard deviations, coefficients of variation, and maximum/minimum indices. The data included maxillary and mandibular tooth dimensions and postcranial metrics. No evidence for selective winnowing based on within‐element size was found in this data set.
