This article analyzes demographic change in Bremen 1815–1914 against the background of changing employment opportunities. Within the pre-industrial employment structure, which still prevailed in the decades after 1850, in-migrants were particularly disadvantaged. When modern industries developed, the situation changed. At the beginning of the twentieth century both male and female in-migrants benefited from a higher life expectancy than the city-born population had. The strong sectoral changes in employment opportunities in Bremen at the turn of the century reinforced the trends towards family limitation. More skilled in-migrants felt the need to adapt their reproductive behavior to facilitate upward social mobility. The article argues for a wider use of archival data, like those used in their study, to explore issues relating to urban demographic change in German cities during industrialization.  相似文献

This article is based on select results taken from a survey of NGO and provincial government policy workers. The purpose is to provide an empirically based assessment of how government and non‐government policy workers engage with one another in the policy process. The data suggest that policy co‐construction and co‐production are a significant feature of the process but there is some need for nuance. The data presented here indicate that the extent of policy engagement may not be as broadly inclusive as the proponents of New Governance suggest.  相似文献

Although scholars have examined committee rosters extensively, no study has considered the relationship between the ideological composition of panels and their participation in bill drafting. I thus ask: Which committees are frequently excluded from legislative deliberations? Does the composition of committees affect the degree to which they contribute to bill development? Using DW‐NOMINATE data, I calculate ideological scores for congressional panels between 1989 and 2010 to see whether certain committees are routinely bypassed. I find that moderate panels, polarized panels, and panels with moderate chairs are often excluded, while extreme committees in the majority direction tend to retain bill‐writing duties.  相似文献

Abstract

Can reinstatement of encoding context aid eyewitness identification? Two experiments are reported in which participants were asked to identify, from both a Blank and a Filled lineup, a target seen 1-week (Experiment 1) or 3-months (Experiment 2) earlier in a staged live interaction. Identifications were made following either a no context reinstatement (NCR), a CI-type reinstate context (CI-CR), a mental and physical (M&PCR) context reinstatement or a multiple reinstatement of context (Multi-CR) manipulation. In Experiment 1 in the Blank lineup condition, correct rejection (CR) and false identification (FID) rates did not differ between the four context manipulation conditions. However, within the different conditions only Multi-CR showed a significant difference between CR and FID. In the Filled lineup condition, neither correct identification (CID), FID, nor non-identification (NID) rates differed between context conditions. Within the four context conditions only Multi-CR produced significantly more CID than FID. However, the difference between CID and NID in this condition did not differ reliably. In Experiment 2, with the Blank lineup, while the rate of CR did not differ between the three context conditions, the rate of FID did, with Multi-CR producing reliably fewer than the other two conditions. In the Filled lineup condition, no differences between the three conditions for NID or FID were observed but a difference did appear for CID, with CI-CR producing the greatest number of hits. These variable results are discussed in terms of the need to consider other factors in explaining supposed context effects on recognition.  相似文献
