Composite hunting technologies from the Terminal Pleistocene and Early Holocene,Niah Cave,Borneo

Renewed archaeological investigation of the West Mouth of Niah Cave, Borneo has demonstrated that even within lowland equatorial environments depositional conditions do exist where organic remains of late glacial and early post-glacial age can be preserved. Excavations by the Niah Cave Research Project (NCP) (2000–2003) towards the rear of the archaeological reserve produced several bone points and worked stingray spines, which exhibit evidence of hafting mastic and fibrous binding still adhering to their shafts. The position of both gives strong indication of how these cartilaginous points were hafted and gives insight into their potential function. These artefacts were recovered from secure and ¹⁴C dated stratigraphic horizons. The results of this study have implications for our understanding the function of the Terminal Pleistocene and Early Holocene bone tools recovered from other regions of Island Southeast Asia. They demonstrate that by the end the Pleistocene rainforest foragers in Borneo were producing composite technologies that probably included fishing leisters and potentially the bow and arrow.     

Population Synthesis: Comparing the Major Techniques Using a Small, Complete Population of Firms

Recently, disaggregate modeling efforts that rely on microdata have received wide attention by scholars and practitioners. Synthetic population techniques have been devised and are used as a viable alternative to the collection of microdata that normally are inaccessible because of confidentiality concerns or incomplete because of high acquisition costs. The two most widely discussed synthetic techniques are the synthetic reconstruction method (IPFSR), which makes use of iterative proportional fitting (IPF) techniques, and the combinatorial optimization (CO) method. Both methods are described in this article and then evaluated in terms of their ability to recreate a known population of firms, using limited data extracted from the parent population of the firms. Testing a synthetic population against a known population is seldom done, because obtaining an entire population usually is too difficult. The case presented here uses a small, complete population of firms for the City of Hamilton, Ontario, for the year 1990; firm attributes compiled are number of employees, 3-digit standard industrial classification, and geographic location. Results are summarized for experiments based upon various combinations of sample size and tabulation detail designed to maximize the accuracy of resulting synthetic populations while holding input data costs to a minimum. The output from both methods indicates that increases in sample size and tabulation detail result in higher quality synthetic populations, although the quality of the generated population is more sensitive to increases in tabular detail. Finally, most tests conducted with the created synthetic populations suggest that the CO method is superior to the IPFSR method.     

State Taxation, Exploration, and Production in the U.S. Oil Industry

Abstract How do firms in nonrenewable resource industries respond to changes in state taxes? This paper presents simulations of changes in state production (severance) tax policy on the timing of exploration and output in Wyoming. The framework developed allows for interactions between taxes levied by different levels of government. Results suggest that oil production is highly inelastic with respect to changes in production taxes. Policy implications suggest that increases in production taxes on oil risk little loss in future production. The extent to which these results may generalize to other oil producing states is considered. JEL Codes: H71, Q32     

Are secessionists making the right arguments for independence?

There are roughly 70 secessionist movements around the world, and all of them advance arguments for why they deserve independence. These include restorative rights, remedial rights, primary rights, a history of conflict and functionality-based arguments. However, no one has conducted a comprehensive analysis to see how these arguments (or grievances) match reality. That is, are secessionists making the right arguments given their context? To answer this question, we utilise a data set of potential secessionist grievances to determine what normative arguments each secessionist movement ought to make given their setting. We conduct a content analysis of the normative appeals/grievances that have actually been made by specific secessionist movements since 2000. We then compare the predicted grievances against the actual grievances and summarise the patterns. The results matched our predictions where restorative rights, remedial rights and functionality-based arguments are concerned. Our analysis returned a positive and statistically significant relationship. However, we found no evidence that those making conflict-related arguments were more likely to exist in conflict settings. Interestingly, the findings for primary rights were the opposite of our expectations; it is the secessionists with the most political voice, not the least, that are the keenest to stress primary rights.     

The Vice President in the U.S. Senate: Examining the Consequences of Institutional Design

The constitutional placement of the vice president as the president of the Senate gives procedural control of the Senate to an individual who is not elected by the chamber. We argue that because the vice president frequently acts against the wishes of Senate majorities, senators have been reluctant to allow chamber power to be centralized under their largely unaccountable presiding officer. This fear has had a major influence on Senate development, preventing the Senate from allowing its chair to reduce dilatory action, as the House has done. Accordingly, delay, via the filibuster, has become commonplace in the Senate. Such delay has reduced the Senate's efficiency, but has largely freed it from the potential influence of the executive branch.
