A preliminary, systematic field study on the process of decomposition and associated insects was conducted, for the first time, in New Zealand. Using pig carcasses as an animal model for human decomposition, insect colonisation and succession was monitored in three different habitats in the Auckland region where remains are likely to be found. A significant difference in the rates of decomposition was found among the three different habitats of an open field, coastal sand dune area and native bush during the autumn/winter season. The primary colonisers of all carcasses were Calliphora stygia Fabricius (Calliphoridae), Chrysomya rufifacies Macquart (Calliphoridae) and Hydrotaea rostrata Robineau-Desvoidy (Muscidae). Two species were identified as possible representatives of the habitats in which they were found; Fannia sp. (Fanniidae) in the open field habitat and Calliphora hilli Patton (Calliphoridae) in the native bush habitat. Also identified was Sylvicola sp. (Anisopodidae) as a possible indicator of damp habitats as well as a likely indicator of a longer postmortem interval. This preliminary investigation presents a broad outline of the insects associated with remains and the order in which they appear in the Auckland region.  相似文献

What is ASPA's place among core public professional organizations as well as public official associations? All public organizations are affected by tough competition for membership. Relatively few members of other public associations join ASPA, and vice versa. Only a minority of faculty members who teach in public affairs programs belong to ASPA, and at top schools, the proportion is even lower. When comparing ASPA to other public official associations, it is smaller in size and broader in scope, yet it remains a uniquely pan‐generalist organization. Its pan‐generalist character puts it at a disadvantage, but also offers distinct advantages. Like all public associations and nonprofits, ASPA faces stiff competition from increasingly specialized associations for membership. Its key future challenge, the authors suggest, will be to match its membership benefits effectively to the rapidly shifting expectations and needs of current and prospective members.  相似文献

Brazil's conditional cash transfer program Bolsa Família (Family Allowance) has gained a worldwide reputation as an effective antipoverty program. However, studies applying the dominant headcount poverty measure, which counts the percentage of households falling below a given poverty line, only credit the program with a first‐order reduction in poverty (and extreme poverty) of 0.15 to 1.88 percentage points. This raises the puzzle of how such a modest impact could lead to Bolsa Família's political popularity. This article argues that Bolsa Família does dramatically reduce poverty, but measuring this impact requires thinking of poverty as how far a household is from meeting its basic human needs; choosing a continuous variable; and using income gap, intensity, and ordinal measures that reflect this conceptualization. The more substantial reduction of poverty intensity helps explain the program's reputation.  相似文献

Scholars have long studied the conditions under which the cabinet making process will result in minority, surplus majority, or minimum-winning governing coalitions in parliamentary systems. Since Riker, a good number of these attempts have been based on rational choice assumptions. Among formal approaches in this vein, Laver and Shepsle’s (Making and breaking governments: Cabinets and legislatures in parliamentary governments, 1996) portfolio allocation model argues that parties centrally located in policy space have a greater potential for being part of any governing coalition and that parties located at the issue-by-issue median have a high likelihood of forming a minority government. However, the model predicts that surplus majority coalitions will only form when the number of salient policy dimensions in the political system is greater than two. We incorporate fuzzy set theory in the portfolio allocation model, permitting us to model ambiguity in parties’ policy preferences. The reformulated model accounts for the formation of surplus majority coalitions in two-dimensional policy space. We illustrate the model’s conclusions with a case study of the 1996 surplus majority coalition in the Lithuanian Seimas.  相似文献

Why are some parties more likely than others to keep the promises they made during previous election campaigns? This study provides the first large‐scale comparative analysis of pledge fulfillment with common definitions. We study the fulfillment of over 20,000 pledges made in 57 election campaigns in 12 countries, and our findings challenge the common view of parties as promise breakers. Many parties that enter government executives are highly likely to fulfill their pledges, and significantly more so than parties that do not enter government executives. We explain variation in the fulfillment of governing parties’ pledges by the extent to which parties share power in government. Parties in single‐party executives, both with and without legislative majorities, have the highest fulfillment rates. Within coalition governments, the likelihood of pledge fulfillment is highest when the party receives the chief executive post and when another governing party made a similar pledge.  相似文献

Abstract

Many states faced fiscal pressures on their corrections budgets as the country entered a deep recession in 2008. A 2011 survey by the Association of State Correctional Administrators (ASCA) asked corrections officials in all 50 states about changes in correctional facilities, focusing on closures, new facilities, and altering existing facilities as a response to budget pressures. States employed a combination of these strategies. Between fiscal year (FY) 2007–2008 and FY 2011–2012, 148 facilities were closed, 29 new facilities were opened, and 23 states added 22,740 beds to existing facilities, resulting in about a 19,000 net bed reduction overall. Closures did not necessarily appear to be related to fiscal pressures or always related to reductions in the prison population. Despite the Great Recession, correctional funding is still a large part of state expenses and many states’ correctional populations continue to grow.  相似文献
