Effects Of Ultrasonication On Damaged Spermatozoa And Mitochondrial Activity Rate, Pinar Peker Akalin, Nuri̇ Başpinar, Kenan Çoyan, Mustafa Numan Bucak, Şükrü Güngör, Caner Öztürk

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to describe an optimal sonication procedure for sperm cells. Therefore, we used several parameters such as damaged spermatozoa rate (%), mitochondrial activity rate (%), levels of lipid peroxidation, and total antioxidant potential. Ejaculates were collected from rams (n = 3) and were divided into aliquots and 3-, 6-, and 10-s duration times; 1, 3, 5, and 8 repetitive application groups were established. In the groups with 3-, 6- and 10-s duration times, with the increasing number of repeated applications, damaged spermatozoa rates increased (P < 0.05) while mitochondrial activity rates decreased (P < 0.05). In relation with sonication duration time, total antioxidant potential levels increased (P < 0.05) in single-application groups compared to those in control groups and gradually decreased as the repetitions increased. The most effective results were obtained in the group with 8 repetitions and 10-s duration based on damaged spermatozoa rate and mitochondrial activity rate.

Age-Related Changes In The Growth Performance, Meat Quality, And Oxidativeprocesses In Breast Muscles Of Three Chicken Genotypes, Monika Michalczuk, Artur Józwik, Krzysztof Damaziak, Zaneta Zdanowska-Sasiadek, Agata Marzec, Dariusz Gozdowski, Nina Strzalkowska

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine growth performance, meat quality, and oxidative changes in breast muscles depending on the genotype and age of broiler chickens. The experiment was conducted on 1080 chickens: fast-growing Cobb 500, medium-growing Hubbard JA957, and a slow-growing experimental line. Chickens from all genetic groups were reared on litter for 8 weeks, but from the 5th week of age, 15 chickens from each group were slaughtered every week. After slaughter at weeks 5, 6, 7, and 8 of chickens? lives, their muscles were sampled for chemical composition, fatty acid profile, and cholesterol. Contents of reduced …

Growth, Slaughter, And Carcass Characteristics Of Honamlı, Hair, And Honamlı X Hair (F1) Male Goat Kids Bred Under Extensive Conditions, Aykut Asim Akbaş, Mustafa Saatci

Turkish Journal of Veterinary & Animal Sciences

Growth and carcass characteristics of Honamlı, Hair, and Honamlı x Hair crossbred goat kids were investigated in this study. Seven kids, having live weights between 25 and 30 kg, were slaughtered. It was found that the live weights of Honamlı, Hair, and Honamlı x Hair kids were 3.90 kg and 27.50 kg, 3.04 kg and 16.91 kg, and 3.58 kg and 22.07 kg at birth and on the 120th day, respectively. Honamlı kids had higher body measurements, as well as birth and live weights, when compared to the other genotypes. While flocks had an important effect (P < 0.001) on all growth periods, the effect of dam age on body measurements was also significant (P > 0.05), except on …

Influence Of Different Proteinaceous Diets On Consumption, Brood Rearing,And Honey Bee Quality Parameters Under Isolation Conditions, Abdulraouf Amro, Mohamed Omar, Ahmed Al-Ghamdi

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to evaluate the efficacy of 5 proteinaceous diets on honey bees under isolation conditions. The diets were soybean meal, mesquite pod powder, date paste, Feedbee®, and corn gluten, along with control colonies (bees fed naturally on pollens). These 5 diets were supplied to honey bee colonies under isolation conditions, except for the control group. Food consumption amount, brood rearing activity, and some physiological parameters of the honey bees were measured. The best consumption amount was for date paste, followed by Feedbee, mesquite, and corn gluten, respectively. Concerning brood rearing activity, the highest mean of sealed …

Influence Of Dietary Vitamin D3 Supplementation On The Sarcomere Length,Warner?Bratzler Shear Force, Shortening Of Ageing Time, And Sensory Acceptanceof Culinary Beef Muscles, Urszula Karolina Rafalska

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the effects of dietary vitamin D3 supplementation on ageing time, tenderness, and consumer acceptance of 3 muscles: longissimus lumborum, semitendinosus, and semimembranosus from crossbreed bulls. Bulls (n = 48) were divided into 4 experimental groups (n = 12 each) that were administered ground oats supplemented with various amounts of vitamin D3 (0.0, 3.5, 7.0, or 10.0 x 106 IU) at 1 day before slaughter. To determine the effect of vitamin D3 addition, changes in tenderness were measured by sarcomere length and Warner?Bratzler shear force (WBSF). In addition, all of the muscles were …

Green Remediation Of Acid Mine Drainage (Amd)-Impacted Soil And Water, Abhishek Roychowdhury

Theses, Dissertations and Culminating Projects

Although mining industries such as coal and minerals generate revenue, they are responsible for a number of negative environmental consequences, and the production of acid mine drainage (AMD) and acid sulfate soil are the most concerning among them. Current AMD management practices are expensive, ineffective, or unsustainable. This study evaluated the potential of a cost-effective and environment-friendly “green” technology in treating AMD-impacted water and soil that utilizes the metal-binding and acid-neutralizing capacity of an industrial by-product, namely drinking-water treatment residuals (WTRs) and the extensive root system of a metal hyper-accumulating, fastgrowing, non-invasive, high biomass perennial grass, vetiver (Chrysopopgon zizanioides …

Competing For Refugees: A Market-Based Solution To A Humanitarian Crisis, Joseph Blocher, Mitu Gulati

Faculty Scholarship

The current refugee crisis demands novel legal solutions, and new ways of summoning the political will to implement them. As a matter of national incentives, the goal must be to design mechanisms that discourage countries of origin from creating refugees, and encourage host countries to welcome them. One way to achieve this would be to recognize that persecuted refugee groups have a financial claim against their countries of origin, and that this claim can be traded to host nations in exchange for acceptance. Modifications to the international apparatus would be necessary, but the basic legal elements of this proposal already …

Pricing Sovereign Debt: Discretion V. Expropriation, Michael Bradley, Irving De Lira Salvatierra, Mitu Gulati

Faculty Scholarship

The Greek restructuring of March 2012 illustrates how non-price contract terms can have a significant effect on the pricing of sovereign debt. In the Greek restructuring, bonds governed by local law suffered NPV haircuts in the range of 60-75%, whereas those bonds governed by foreign law were paid in full and on time. Other contract parameters such as the currency in which the debt is denominated and the exchange on which it is listed can also affect the leeway a sovereign debtor has in dealing with its creditors. In general, we find that sovereigns with strong institutions and investor protections …

Perspectives On Regulating Systemic Risk, Steven L. Schwarcz

Faculty Scholarship

This book chapter, which synthesizes several of the author’s articles, attempts to provide useful perspectives on regulating systemic risk. First, it argues that systemic shocks are inevitable. Accordingly, regulation should be designed not only to try to reduce those shocks but also to protect the financial system against their unavoidable impact. This could be done, the chapter explains, by applying chaos theory to help stabilize the financial system. The chapter then focuses on trying to prevent excessive corporate risk-taking, which is one of the leading triggers of systemic shocks and widely regarded to have been a principal cause of the …

Cultural Paradigms In Property Institutions, Taisu Zhang

Faculty Scholarship

Do “cultural factors” substantively influence the creation and evolution of property institutions? For the past several decades, few legal scholars have answered affirmatively. Those inclined towards a law and economics methodology tend to see property institutions as the outcome of self-interested and utilitarian bargaining, and therefore often question the analytical usefulness of “culture.” The major emerging alternative, a progressive literature that emphasizes the social embeddedness of property institutions and individuals, is theoretically more accommodating of cultural analysis but has done very little of it.

This Article develops a “cultural” theory of how property institutions are created and demonstrates that such …

Neighborhoods By Assessment: An Analysis Of Non-Ad Valorem Financing In California, Mathew D. Mccubbins, Ellen C. Seljan

Faculty Scholarship

Non-ad valorem assessments on property are a fiscal innovation born from financial stress. Unable to raise property taxes due to limitations, many localities have turned to these charges as an alternative method to fund local services. In this paper, we seek to explain differential levels of non-ad valorem assessment financing through the analysis of property tax records of a large and diverse set of single family homes in California. We theorize that assessments, as opposed to other forms of taxation, will be used when residents hold anti-redistributive preferences. We show that assessment financing is most common in cities with high …

Towards A New International Law Of The Atmosphere?, Peter H. Sand, Jonathan B. Wiener

Faculty Scholarship

Inclusion of the topic ‘protection of the atmosphere’ in the current work programme of the UN International Law Commission (ILC) reflects the long overdue recognition of the fact that the scope of contemporary international law for the Earth’s atmosphere extends far beyond the traditional discipline of ‘air law’ as a synonym for airspace and air navigation law. Instead, the atmospheric commons are regulated by a ‘regime complex’ comprising a multitude of economic uses including global communications, pollutant emissions and diffusion, in different geographical sectors and vertical zones, in the face of different categories of risks, and addressed by a wide …

Agency Costs In Law-Firm Selection: Are Companies Under-Spending On Counsel?, Elisabeth De Fontenay

Faculty Scholarship

A growing body of literature examines whether corporate clients derive sufficient value from the law firms that they engage. Yet little attention has been paid to whether clients optimally select among law firms in the first place. One entry-point is to identify discrepancies in the quality of counsel selected by different corporate clients for the very same work. Using a large sample of loans, this Article finds that major U.S. public companies select lower-ranked law firms for their financing transactions than do private equity-owned companies, controlling for various deal characteristics. While some of this discrepancy can be attributed to value-maximizing …

Accessory Disloyalty: Comparative Perspectives On Substantial Assistance To Fiduciary Breach, Deborah A. Demott

Faculty Scholarship

Culpable participation in a fiduciary's breach of duty is independently wrongful. Much about this contingent form of liability is open to dispute. In the United States, well-established general doctrine defines the elements requisite to establishing accessory liability, which is categorized as a tort and often referred to as "aiding-and abetting" liability. What's controversial is how the tort applies to particular categories of actors, most recently investment banks that advise boards of target companies in M&A transactions. In the United Kingdom, in contrast, accessory liability in connection with a breach of trust or fiduciary duty is controversial because the law is …

Culpable Participation In Fiduciary Breach, Deborah A. Demott

Faculty Scholarship

This essay makes a case for the salience of tort law to fiduciary law, focusing on actors who culpably participate in a fiduciary's breach of duty, whether by inducing the breach or lending substantial assistance to it. Although the elements of this accessory tort are relatively settled in the United States, how the tort applies to particular categories of actors-most recently investment bankers who serve as M&A advisors-provokes controversy. The paper also explores the less developed terrain of primary actors who breach governance duties that are not fiduciary obligations because the entity's organizational documents eliminate fiduciary duties, as Delaware law …

Shadow Banking And Regulation In China And Other Developing Countries, Steven L. Schwarcz

Faculty Scholarship

The rapid but largely unregulated growth in shadow banking in developing countries such as China can jeopardize financial stability. This article discusses that growth and argues that a regulatory balance is needed to help protect financial stability while preserving shadow banking as an important channel of alternative funding. The article also analyzes how that regulation could be designed.

Contract Development In A Matching Market: The Case Of Kidney Exchange, Kimberly D. Krawiec, Wenhao Liu, Marc L. Melcher

Faculty Scholarship

We analyze a new transplant innovation — Advanced Donation, referred to by some as a kidney “gift certificate,” “layaway plan,” or “voucher — as a case study offering insights on both market and contract development. Advanced Donation provides an unusual window into the evolution of the exchange of a single good — a kidney for transplantation — from gift, to simple barter, to exchange with a temporal separation of obligations that relies solely on trust and reputational constraints for enforcement, to a complex matching market in which the parties rely, at least in part, on formal contract to define and …

Elections, Ideology, And Turnover In The U.S. Federal Government, Alexander D. Bolton, John De Figueiredo, David E. Lewis

Faculty Scholarship

A defining feature of public sector employment is the regular change in elected leadership. Yet, we know little about how elections influence public sector careers. We describe how elections alter policy outputs and disrupt the influence of civil servants over agency decisions. These changes shape the career choices of employees motivated by policy, influence, and wages. Using new Office of Personnel Management data on the careers of millions of federal employees between 1988 and 2011, we evaluate how elections influence employee turnover decisions. We find that presidential elections increase departure rates of career senior employees, particularly in agencies with divergent …

Public Sector Personnel Economics: Wages, Promotions, And The Competence-Control Trade-Off, Charles M. Cameron, John De Figueiredo, David E. Lewis

Faculty Scholarship

We model personnel policies in public agencies, examining how wages and promotion standards can partially offset a fundamental contracting problem: the inability of public sector workers to contract on performance, and the inability of political masters to contract on forbearance from meddling. Despite the dual contracting problem, properly constructed personnel policies can encourage intrinsically motivated public sector employees to invest in expertise, seek promotion, remain in the public sector, and develop policy projects. However, doing so requires internal personnel policies that sort "slackers" from "zealots." Personnel policies that accomplish this task are quite different in agencies where acquired expertise has …

Dealing With Illegal Housing: What Can New York City Learn From Shenzhen?, Shitong Qiao

Faculty Scholarship

In New York City, owners violated zoning regulations and opened up their basements, garages, and other floors to rent to people (particularly low-income immigrants) priced out of the formal market. The more than 100,000 illegal dwelling units in New York City (NYC) were referred to as “granny units,” “illegal twos or threes,” or “accessory units.” Due to the safety and habitability considerations of “alter[ing] or modif[ying] of an existing building to create an additional housing unit without first obtaining approval from the New York City Department of Buildings (DOB),” the City government devoted a lot of resources to detecting and …

The Coherence Of Conceptual Primitives, Jamie C. Macbeth, Marydjina Barionnette

Computer Science: Faculty Publications

Intelligent systems that process natural language need representations of knowledge to support a human-like thought process, and they often use natural language words or phrases to name and represent concepts in a knowledge base. But some theories of cognition claim that language and thought are not the same thing, and that human thought processes occur at a deeper level of representation than words and phrases in language. In this paper we present results of a human subjects study of language-free primitive decomposition as a representation for commonsense knowledge. We found that our subjects could comprehend and use a primitive decomposition …

Regulating Financial Change: A Functional Approach, Steven L. Schwarcz

Faculty Scholarship

How should we think about regulating our dynamically changing financial system? Existing regulatory approaches have two temporal flaws. The obvious flaw, driven by politics and human nature (and addressed in other writings), is that financial regulation is overly reactive to past crises. This article addresses a less obvious but arguably more fundamental flaw: that financial regulation is normally tethered to the financial architecture, including the distinctive design and structure of financial firms and markets, in place when the regulation is promulgated. In order to effectively address future crises, this article argues, financial regulation must transcend that time-bound architecture. This could …

Race, Class, And Access To Civil Justice, Sara Sternberg Greene

Faculty Scholarship

After many years of inattention, policymakers are now focused on troubling statistics indicating that members of poor and minority groups are less likely than their higher-income counterparts to seek help when they experience a civil justice problem. Indeed, roughly three-quarters of the poor do not seek legal help when they experience a civil justice problem, and inaction is even more pronounced among poor blacks. Past work on access to civil justice largely relies on unconfirmed assumptions about the behavior patterns and needs of those experiencing civil justice problems. At a time when increased attention and resources are being devoted to …

Manufacturing Barriers To Biologics Competition And Innovation, W. Nicholson Price Ii, Arti K. Rai

Faculty Scholarship

As finding breakthrough small-molecule drugs gets harder, drug companies are increasingly turning to “large molecule” biologics. Although biologics represent many of the most promising new therapies for previously intractable diseases, they are extremely expensive. Moreover, the pathway for generic-type competition set up by Congress in 2010 is unlikely to yield significant cost savings.

In this Article, we provide a fresh diagnosis of, and prescription for, this major public policy problem. We argue that the key cause is pervasive trade secrecy in the complex area of biologics manufacturing. Under the current regime, this trade secrecy, combined with certain features of FDA …
