An investigation is conducted on the effect of financial distress on customer service levels in the U.S. airline industry. Using data from the first quarter of 1998 to the third quarter of 2006, we employ a seemingly unrelated regressions (SUR) model to analyze the impact of financial distress on three measures of customer service. We find that higher financial distress is associated with better on-time performance of airlines and fewer lost bags. The relationship of airline financial distress to the number of bumped customers, however, is insignificant.

A formal approximate solution is derived for the profile and velocity components of a wave with permanent form of finite height m moderate water depths. The approximation is carried to the third order, sufficiently far to represent all except the very high "design" waves. The relationship of the formulas to others found in the literature is discussed. The wavelengths and the coefficients in the third-order series for the wave profile, and the water particle velocities and local accelerations are tabulated for approximately 2000 waves. The depths, heights, and periods for the listed wave conditions vary respectively from 10 to 500 feet, 5 to 40 feet, and 4 to 20 seconds. The range of applicability of the theory is discussed and approximate limits estimated. As an aid in calculations, tables of the trigonometric and hyperbolic sines and cosines for integral multiples of the argument are included.

The article reflects the diversity of views on the concept of "legal axiom". It is clarified that there are lawyers who deny the existence of the concept of "axiom" in law. It is presented that some scholars identify legal axioms with legal customs in terms of content, formulation and existence, as well as methods of provision. It is revealed that legal axioms have common features and differences with legal presumptions. It is emphasized that the legal presumption and legal axiom are understood as true without evidence. It is considered that the difference between a legal presumption and a legal axiom lies in the difference of circumstances: they allow to consider them plausible; possibilities (impossibilities) of refutation; significance, content and form It is demonstrated that there are several approaches to the relationship of legal axioms with the principles of law. It has been found that the first group of scholars identify the principles of law and axioms. Attention is drawn to the fact that the second group of scholars notes that axioms are prerequisites for the principles of law. It is presented that the representatives of the third group distinguish between the concepts of principles of law and legal axioms. It has been shown that the complex interrelationships of principles and axioms are reflected in their dialectical unity, their ability to pass from one to another, and the disclosure of one phenomenon through another. It is noted that axioms are subject to change, so axioms and presumptions are closely interrelated and under certain conditions can replace each other. The definition of legal axioms has been further considered. Legal axioms are a multifaceted complex phenomenon of legal reality related to law, legal awareness and legal science. regularities, properties of special legal principles of law and serve to simplify legal regulation.

This prologue provides an overview of the history of early and medieval West Africa. During this period, the rise of Islam, the relationship of women to political power, the growth and influence of the domestically enslaved, and the invention and evolution of empire were all unfolding. In contrast to notions of an early Africa timeless and unchanging in its social and cultural categories and conventions, here was a western Savannah and Sahel that from the third/ninth through the tenth/sixteenth centuries witnessed political innovation as well as the evolution of such mutually constitutive categories as race, slavery, ethnicity, caste, and gendered notions of power. By the period's end, these categories assume significations not unlike their more contemporary connotations. All of these transformations were engaged with the apparatus of the state and its progression from the city-state to the empire. The transition consistently featured minimalist notions of governance replicated by successive dynasties, providing a continuity of structure as a mechanism of legitimization. Replication had its limits, however, and would ultimately prove inadequate in addressing unforeseen challenges.

The aim of the study is to reveal the existence of an abnormal return in the city indices in Borsa Istanbul. Three important calculations were made for the detection of an abnormal return. The first was the calculation of adjusted returns. The second was the calculation of beta coefficients for city indices. The third was the determination of the relationship of each city index to the market. According to the findings obtained, there was an abnormal return in the city indices. In other words, each of the city indices made a profit on market returns. However, these returns were almost equal to market returns. When the beta coefficients were analyzed, it was seen that the coefficients were equal to the theoretically-expressed average market beta coefficient. Thus, the city indices and the market are moving in the same direction, and the results are statistically significant.

Chapter 15 summarizes the chapters which addressed the third sphere, the relationship of labor to the political community. It reiterates that since Israel was established, the labor market’s borders have become ever more porous, while the borders of the national (Jewish) political community have remained firm: the Jewish nationalism which guides government policy is as strong as ever. NGOs, drawing on a discourse of human rights, are able to assist some non-citizens but this discourse also resonates with the idea of individual responsibility: the State is no longer willing to support “non-productive” populations, who are now being shoehorned into a labor market which offers few opportunities for meaningful employment, and is saturated by cheaper labor intentionally imported by the State in response to powerful employer lobbies. These trends suggest a partial reorientation of organized labor’s “battlefront”, from a face-off with capital to an appeal to the public and state.

A total of 1,457 clean fleece weights, representing 7 years of production and adjusted for certain environmental factors, were used in this study. The data were analysed to determine the relationship of clean fleece weight to age in the Rambouillet, Romnelet, and Canadian Corriedale breeds of range sheep maintained under Western Canadian conditions.In general, maximum fleece weight was attained by the second year of production and was maintained until the end of the fourth year in all breeds. At that time a significant (p <.01) decline occurred which continued until the end of the seventh year. Among the Rambouillet and Romnelet ewes which were born and raised as singles, a small additional increase in average fleece weight occurred in the third year. Ewes born and raised as singles tended to produce more wool than twins but the differences were significant (p <.01) only in the Romnelet shearlings. The data suggest that in twins maximum production occurred at a slightly earlier age and that the subsequent decline began sooner than in singles.

This article maintained that the historicity of Jesus’ baptism was intended to flesh out the righteousness of God that was well-documented in the Hebrew Scriptures. Furthermore, the historical event initiated the ontological emphasis on the relationship of baptism to righteousness. To support this proposal, this article focused on Matthew’s fulfilment statement in Matthew 3:15. Looking specifically at this verse within its context, the article examines what Matthew may have intended for his community to grasp regarding the Christian tradition of righteousness. The article is divided into four sections that are intended to examine Matthew’s intentions. Firstly, the immediate context is examined, showing the influences and setting for the fulfilment statement. The following section explores the fulfilment statement within this context. The third section uncovers some of the theological traditions in Paul and the church fathers. Finally, the baptismal statement of Matthew 3:15 will be tied directly to the relationship of the law and righteousness in Matthew’s ἦλθον statement of Matthew 5:17. Hierdie artikel betoog dat die historiese waarheid van Jesus se doop bedoel was om die geregtigheid van God, wat volledig uiteengesit is in die Hebreeuse Bybel, te versterk. Verder het die historiese gebeurtenis die ontologiese klem op die verhouding van die doop tot geregtigheid geïnisieer. Om hierdie voorstel te ondersteun, fokus hierdie artikel op Matteus se verklaring van verwesenliking (Mat 3:15). Deur spesifiek na hierdie vers binne sy konteks te kyk, ondersoek die artikel wat Matteus moontlik beplan het sodat sy gemeenskap die Christelike tradisie van geregtigheid kon begryp. Die artikel is in vier afdelings verdeel om sodoende Matteus se bedoelings te ondersoek. Eerstens word die onmiddellike konteks ondersoek wat die invloede en agtergrond van die verklaring van die verwesenliking uitwys. In die volgende afdeling word die verklaring van die verwesenliking in hierdie konteks verken. In die derde afdeling word ’n paar van die teologiese tradisies van Paulus en die kerkvaders aan die lig gebring. Ten slotte is die doopverklaring van Matteus 3:15 regstreeks aan die verhouding van reg en geregtigheid in Mattheus se ἦλθον verklaring van Matteus 5:17 gekoppel.
