The economic organization of legislatures and how it affects congressional voting

Congress confronts two major organizational problems that affect the behavior of legislators, party leaders, and groups doing business with congressional committees: The costly nature of monitoring and the absence of explicit mechanisms for upholding agreements. The problem of monitoring implies that party leaders will have a difficult time influencing decisions made in decision-making arenas where the actions of legislators are less visible, as in congressional committees. While legislators can evade leadership monitoring of their actions within committees, once an issue leaves a committee, the costs of monitoring decline, and leadership influence increases. The absence of mechanisms for assuring that legislators keep their bargains means that groups will place an emphasis on dealing with reliable legislators — those who can be counted upon to uphold their end of a bargain. Thus, party leaders are more effective in influencing floor voting because of their better ability to monitor legislator behavior; however, obligations to important interest groups will be more immune to leadership influence because of the incentives for committee members to adhere to their bargains.     

State Tax Credits and "Making Work Pay" in Post-Welfare Reform Era

This article outlines the work incentives and income support provided by the federal Earned Income Tax Credit (EITC) and illustrates how state earned income and dependent care credits assist working poor families. State earned income and dependent care tax credits serve as critical complements to the EITC, the federal government's largest antipoverty program. By attending to specific components of each tax credit, state policymakers can maximize state funds that qualify for federal maintenance of effort requirements under the Personal Responsibility and Work Opportunity Reconciliation Act (PROWRA), and they can reinforce positive effects and offset work disincentives stemming from current federal tax parameters.     

Reputational capital, opportunism, and self-policing in legislatures

This paper examines the question of whether reputational capital can deter opportunistic behavior among legislators preparing to exit the House of Representatives. I create a measure of reputational trustworthiness, based upon pooled samples of constituency opinion derived from the National Election Studies surveys. I then examine the extent to which such reputational good will among constituents deters lame-duck foreign travel by exiting House incumbents within the context of a quasi-experimental research design. The analysis suggests that legislators may be ‘self-policed’ by their reputations for honesty and trustworthiness to the point of discouraging unethical activity. urveys. I then examine the extent to which such s derived from the National Election Studies     

The CIA and congressional oversight: learning and forgetting lessons

Organizations both learn lessons and forget lessons. A lesson said to be learned by the CIA as a result of the negative reaction of congressional overseers to its interrogation program was the need to create opportunities to provide information and interact with them. The historical record shows that this was a lesson already learned. Why then the need to relearn it? It is suggested here that organizational forgetfulness may be triggered by the same factors which promote learning: perceived problems with organizational performance, opportunities to act, and people.     

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.

Significant Differences in PostMortem Heart Weight Before and After Dissection Using the Short-Axis Dissecting Method

Correctly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short-axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study.
