When and How Parliaments Influence Foreign Policy: The Case of Turkey's Iraq Decision

Turkey's decision on its role in the Iraq war in 2003 illustrates the power—and limits—of parliaments as actors in foreign policy. Traditionally, assemblies are not seen as important players in the foreign policies of parliamentary democracies. Instead, cabinets are generally considered the chief policymaking authorities. If the government enjoys a parliamentary majority, legislatures typically support the cabinet, if they are brought into the process at all. The March 1, 2003 vote by the Turkish parliament to not allow the United States to use Turkey as a base for the Iraq invasion challenges this conventional wisdom on parliamentary influence (in addition to many interest-based explanations of foreign policy). This paper examines this decision in the context of the role of parliaments in foreign policies and explores the relationships between parliamentary influence, leadership, intraparty politics, and public opinion.     

The Effect of Media on Charitable Giving and Volunteering: Evidence from the “Give Five” Campaign

Fundraising campaigns advertised via mass media are common. To what extent such campaigns affect charitable behavior is mostly unknown, however. Using giving and volunteering surveys conducted biennially from 1988 to 1996, I investigate the effect of a national fundraising campaign, “Give Five,” on charitable giving and volunteering patterns. The widely advertised Give Five campaign was aimed to encourage people to give 5 percent of their income and volunteer 5 hours a week. After controlling for selection into being informed about the Give Five, I find that people who were informed about the campaign increased their weekly volunteering activity on average by almost half an hour, but their giving behavior was not significantly affected. I discuss the policy implications associated with this result and argue that although the Give Five campaign did not achieve its goal, its impact on volunteering was considerable. © 2012 by the Association for Public Policy Analysis and Management.     

Improved estimation of postmortem interval based on differential behaviour of vitreous potassium and hypoxantine in death by hanging

Many formulae are available to estimate the relation between the potassium ([K+]) and hypoxantine ([Hx]) concentration in the vitreous humour and the postmortem interval (PMI). Typically these have been based on a correlation test and linear regression using the postmortal interval as the independent variable and [K+] or [Hx] as the dependent variable in order to estimate the confidence interval. However, a recent study has shown that a more precise measurement of PMI can be obtained if [K+] is used as the independent variable. The regression lines obtained from the most recent deceased subjects with forensic relevance received for autopsy in the Institute of Legal Medicine are [K+] = 5.589 + 0.174PMI and [Hx] = 26.459 + 3.017PMI, by changing the variables, we obtain PMI=3.967[K+] - 19.186 (R2 = 0.688, P < 0.001) and PMI = 0.172 [Hx] + 0.170 (R2 = 0.518, P < 0.001). In this paper we propose the cause of death as an extra factor which modifies the relationship and gives even greater precision in estimating PMI. In cases of death by hanging the results are considerably improved with [K+] = 5.224 + 0.225PMI and [Hx] = 15.161+4.957PMI, respectively, and consequently, PMI = 3.631[K+] - 17.334 (R2 = 0.818, P< 0.001) and PMI = 0.153[Hx] - 0.368 (R2 = 0.757, P < 0.001): the slope is less and the precision is obviously enhanced.
