The Intentions of Early-Career Nurses to Continue Working

The purpose of this study was to identify the factors that cause female nurses to terminate work early in their nursing careers. A survey of 808 nurses less than ten years into their careers was conducted, covering background factors (age, education, workplace, night shifts, working hours, instructional role), psychological factors (organizational commitment, job satisfaction, reality shock), and the intention to continue work following marriage and/or childbirth. A covariant structure analysis was conducted on 405 valid samples to examine the relative influence of these three factors. The results indicated that working nights lowered nurses' organizational commitment and that reality shock had a negative effect on their intention to continue working. It was also found that playing an instructional role increased organizational commitment, helped nurses overcome reality shock, and had a positive effect on their intention to continue working.
Characterization of catalytically active sites on aluminum oxides, hydroxyfluorides, and fluorides in correlation with their catalytic behavior

Temperature-programmed desorption of ammonia has been employed for the characterization of halogen exchange catalysts. Nonactivated and activated catalysts are compared in regard to their behavior in adsorption and desorption. Activation of γ-alumina and AlF 2 (OH) increases both the catalytic activity for halogen exchange and the amount and strength of ammonia adsorption. In constrast, β-AlF 3 possesses catalytic activity already without activation. This substance reveals no significant alteration of ammonia adsorption after activation. A connection was observed between the acidity of the catalysts and their reactivity. The nature of the acidic sites was determined by Fourier transform infrared photoacoustic spectroscopy of pyridine chemisorbed on the solid surfaces. The results indicate that Lewis acid sites of a certain strength are responsible for the catalytic activity.

Market structure and the value of overselling under stochastic demands

In the operations management literature, traditional revenue management focused on pricing and capacity allocation strategies in a two-period model with stochastic demand. Inspired by travel and lodging industries, we examine a two-period model in which each seller may also adopt the overselling strategy to customers whose valuations are differentiated by timing of arrivals. Widely seen as a popular hedge against consumers’ skipping reservations, we extend the stylized approaches of Biyalogorsky, Carmon, Fruchter, and Gerstner (1999) and Lim (2009) to understand the value of overselling under various market structures. We find that contrary to existing literature, the impact of period-two pricing competition from overselling spills over to period-one such that overselling may not always be a (weakly) dominant strategy once unlimited early demand ceases to hold in a duopoly regime. We provide some numerical studies on the existence of multiple equilibria at the capacity allocation level which actually lead to different selling strategies at the equilibrium despite identical market conditions and firm characteristics.
Usage signatures analysis an alternative method for preventing fraud in E-Commerce applications

From small local businesses to large multinationals, we can find a lot of initiatives in order to put their business online. E-Commerce is rapidly expanding worldwide with the emergence of new web shops, business to business services, or payment services, just to name a few. E-Commerce companies have been continuously improving their business incomes and extending their influence in the market. However, this proliferation of online business raised a very old phenomenon: fraud. Consequently, E-Commerce companies lose significant amounts of money every year due to a large diversity of fraudulent cases. This phenomenon is quite difficult to manage and handle, requiring significant efforts, both human and financial, in its identification and treatment. In this paper we present and discuss the use of signatures on the detection of potential fraud situations in an E-Commerce Web application, showing the way signatures are processed and analysed, as well as they can contribute to establish user behaviour deviation and consequently detect potential fraud situations in useful time.
Microstructure and Mechanical Properties of Ceramic Composites

Ceramic matrix composites reinforced with metals have been developed to overcome the intensive brittleness and lack of reliability of monolithic ceramics, with a view to introduce ceramics in structural parts used in severe environments such as rocket and jet engines, gas turbines for power plants, heat shields for space vehicles, fusion reactor first wall, aircraft brakes, heat treatment furnaces. In view of these the effects of Al-6%Si alloy particles on the ascast microstructure and properties of Tin Tailings ceramics matrix composites produced by powder metallurgy method have been studied. 5-30 weight percent Al-6%Si alloy particles were added. The results revealed that, addition of Al-6%Si alloy reinforcement increased the linear shrinkage, strength and impact energy with a decreased in density, porosity and hardness value. These increases in strength and impact energy are attributed to the uniform distribution and strong bonding of the soft metal phase in the hard ceramic matrix. These results show that better properties are achievable by addition of Al-6%Si alloy to Tin Tailings.
Improving the Existence Bounds for Grid-Block Difference Families

In this paper, by employing Weil’s Theorem on multiplicative character sums, an intermediate algebraic consequence on the existence bound of an element satisfying certain cyclotomic conditions in a finite field is proposed. In many cases, this approach improves the bound due to Buratti and Pasotti (Finite Fields Appl 15(3), 332–344, 2009), which can be widely used for showing the asymptotic existence of combinatorial designs with point-regular automorphisms. Moreover, this approach is applied to improving the existence bound for grid-block difference families, which can be regarded as generalizations of difference families.
A Discussion on Intrusion Epochs of Granodiorites along the Bagexia-Heidaban Zone in the Western Part of the North Qilian Mountains

No isotopic dating of granodiorites along the Bagexia-Heidaban zone in the western part of North Qilian Mountains was made by previous workers.They were commonly thought to be products of Late Variscan.Nevertheless,U-Pb single-zircon dating conducted by the authors show that these granodiorites are 481.6±3.3 Ma in age,thus belonging to Ordovician.The Altun fault belt might have been formed earlier than 481.6±3.3 Ma.Geological significance of these age data is also discussed in this paper.
Notes on Computable Analysis

Computable analysis has been part of computability theory since Turing’s original paper on the subject (Turing,  1936). Nevertheless, it is difficult to locate basic results in this area. A first goal of this paper is to give some new simple proofs of fundamental classical results (highlighting the role of Π10${{\Pi }_{1}^{0}}$ classes). Naturally this paper cannot cover all aspects of computable analysis, but we hope that this gives the reader a completely self-contained ingress into this area. A second goal is to use tools from effective topology to analyse the Darboux property, particularly a result by Sierpiński, and the Blaschke Selection Theorem.
Characteristics and anticorrosion performance of Fe-doped TiO2 films by liquid phase deposition method

Fe-doped TiO 2 thin films were fabricated by liquid phase deposition (LPD) method, using Fe(III) nitrate as both Fe element source and fluoride scavenger instead of commonly-used boric acid (H 3 BO 3 ). Scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV–vis spectrum were employed to examine the effects of Fe element on morphology, structure and optical characteristics of TiO 2 films. The as-prepared films were served as photoanode applied to photogenerated cathodic protection of SUS304 stainless steel (304SS). It was observed that the photoelectrochemical properties of the as-prepared films were enhanced with the addition of Fe element compared to the undoped TiO 2 film. The highest photoactivity was achieved for Ti13Fe (Fe/Ti = 3 molar ratio) film prepared in precursor bath containing 0.02 M TiF 4  + 0.06 M Fe(NO 3 ) 3 under white-light illumination. The effective anticorrosion behaviors can be attributed to the Fe element incorporation which decreases the probability of photogenerated charge-carrier recombination and extends the light response range of Fe-doped TiO 2 films appeared to visible-light region.
Economistes, experts et politiques

How can we explain that economics, characterised by an impressive logic and by unquestionable progresses, is also marked by more theoretical inability and self-limitation and that in the same time, the power of economists and the scope of the economist speech are gaining in importance ? With the notions of legality, legitimacy, certainty, science, opinion, we briefly show that power uses uncertainty facing the opinion and that the role played by experts between politicians and the opinion is essential to the management of this uncertainty. We also demonstrate that this self limitation of economics (its self destruction) is related to the triumph of the expert economics. The economist, in his own work, has to deconstruct the economic reality proposed by experts, and to deconstruct the model meant for the politic body; it is part of its status and of its scientist's contract.
A different kind of blonde: Melina Mercouri in Stella (Michael Cacoyannis, 1955)

This article discusses the blondness of Melina Mercouri: the first Greek blond star and Greece’s most popular cinematic export. Taking as a case study her breakthrough role as Stella in the 1955 film of the same title, the article examines the aesthetic and political significance of Mercouri’s blondness within the historical context from which her star image emerged, namely post-war Greece, and wherein it circulated, that is Euro-American culture. The main aim of the analysis is to shed light on the bold and unconventional kind of blondness Mercouri embodied and promoted.

"History and its Images. Art and the Interpretation of the Past", Francis Haskell, New Haven-London 1993 : [recenzja] / Zygmunt Waźbiński.

Over the last four centuries, historians have increasingly turned to images in their attempts to understand and visualize the past. In this wide-ranging and engrossing book, a distinguished art historian surveys the various ways that they have adopted for making use of this material, and he examines the specific objects that became available to them through excavation, the creation of private collections and public museums, easier means of travel, and the startling displacements brought about by vandalism and art exhibitions. Francis Haskell begins by discussing the antiquarians of the sixteenth and seventeenth centuries who brought to light and interpreted as historical evidence coins, sculptures, paintings discovered in the catacombs beneath Rome and other relics surviving from earlier ages. He explains that, in the eighteenth century, historians gradually began to acknowledge the significance of such visual sources and to draw on them in order to validate and give colour to their narratives or to utilize them as foundation stones for a new branch of learning - the history of culture. Later writers followed the example of Michelet in making inferences from the visual arts to indicate the whole mentality of an age, while (more erratically) others saw in them the harbingers of political, religious or social upheavals. Haskell concludes by discussing those cultural historians of the nineteenth and early twentieth centuries, Burckhardt and Huizinga above all, who did not merely give the visual arts a prominent and necessary place in their interpretations of the past, but in some ways actually interpreted the past through the visual arts.
Settlement's Dynamics in Western Sicily between VIII E IV Sec. B.C. A Geographic Information System to Research

Terms and technologies that would be not comprehensible to the archaeologists of the past are now widely spreading inside landscape archaeology fields, beginning from those sites where the enormous proportion of picked data and the continuous overlap of the layers makes difficult to understand what happened. In this context, the use of the GIS (Geographical Information System) has known a remarkable success, according to the increasing necessity to archive, elaborate and analyze the great quantity of archaeological data coming from surveys, as in the case of Iato and Belice river valleys (Sicily).
Kinetics of monosaccharide conversion in the presence of homogeneous Bronsted acids

For the utilization of biomass in the fuel and polymer industry, a wide variety of catalysts have been studied for their activity either on the dehydration reaction in particular or on the monosaccharide degradations in general. Yet, systematic data outlining the effects of acidic features is not available and a common framework for catalytic activity comparison is missing that is needed for rational catalyst design. The current work aimed to provide insight about the effect of the nature of the acid and initial acidity on degradation kinetics of C 5 and C 6 carbohydrates and thereby built a platform allowing activity comparison. Mineral and organic acids ranging in acidic strength, hydrochloric, sulfuric, phosphoric, maleic, and propane sulfonic acid, were tested for their activity in the degradation of xylose, fructose and glucose at two different pH values; 1.5 and 3.6. In the presence of weak homogeneous acids, glucose undergoes degradation with drastically different activation energies at pH of 1.5 than at pH 3.6. Such a difference does not occur in the presence of strong homogenous acids. On the other hand, xylose and fructose undergo degradation with similar activation energies of approximately 140 kJ/mol regardless of the pH or nature of the homogeneous acid. A common framework that compiles the catalytic activities and outlines the differences potentially related to underlying mechanism changes provides the basis required for rational heterogeneous catalyst design.

Changes in the Social Structure of Russian Society at the End of the Seventeenth and the Beginning of the Eighteenth Century

In recent years scholars have shown intense interest in the history of slavery in Russia. In their writings, E. N. Kushevaia, V. M. Paneiakh, E. I. Kolychevaia, A A. Zimin, and others have closely analyzed the socioeconomic position and legal status of slaves, the development of the institution of slavery and the part it played in enserfing the
What is the Correct Logic of Necessity, actuality and apriority?

This paper is concerned with a propositional modal logic with operators for necessity, actuality and apriority. The logic is characterized by a class of relational structures defined according to ideas of epistemic two-dimensional semantics, and can therefore be seen as formalizing the rela- tions between necessity, actuality and apriority according to epistemic two-dimensional semantics. We can ask whether this logic is correct, in the sense that its theorems are all and only the informally valid formulas. This paper gives outlines of two arguments that jointly show that this is the case. The first is intended to show that the logic is informally sound, in the sense that all of its theorems are informally valid. The second is intended to show that it is informally complete, in the sense that all informal validities are among its theorems. In order to give these arguments, a number of independently interesting results concerning the logic are proven. In particular, the soundness and completeness of two proof systems with respect to the semantics is proven (Theorems 2.11 and 2.15), as well as a normal form theorem (Theorem 3.2), an elimination theorem for the actuality operator (Corollary 3.6), and the decidability of the logic (Corollary 3.7). It turns out that the logic invalidates a plausible principle concerning the interaction of apriority and necessity; consequently, a variant semantics is briefly explored on which this principle is valid. The paper concludes by assessing the implications of these results for epistemic two-dimensional semantics.
Broxyquinoline and brobenzoxalidine suspension (Intestopan-AI 307) in childhood diarrhoea

SummaryA clinical trial of Intestopan suspension was undertaken on 413 cases of acute diarrhoea (group A) and 120 cases of chronic diarrhoea (group B). The third group C of 178 cases was treated with other drugs to have a comparative assessment of Intestopan.A satisfactory response with Intestopan was obtained in 69.1% cases as compared to 67.4% cases of group C, and 11.4% cases in group A died as compared to 21.9% of group C. The type of response in acute diarrhoea with dehydration was primarily conditioned by the degree of dehydration. The mortality in cases with severe dehydration was 55.3% and in those with moderate and mild dehydration 42.6% and 2.1% respectively. The highest incidence of satisfactory response with Intestopan therapy was in cases above the age of 18 months.A satisfactory response in the chronic diarrhoea cases (group B) on Intestopan therapy was observed in 77.8% over 12 weeks of follow up. The initial, as well as the follow up response, was not affected by the duration of diarrhoea. The satisfactory response was maximum in those above 18 months of age (86.2%) compared to those below 18 months (65.1%).No side effects with Intestopan were met with in the present trial.
Water Use in Coastal Georgia by County and Source for 1997 and Trends, 1980-97

Water use during 1997 was estimated for each county in the 24-county area of coastal Georgia by water-use category, using data obtained from various Federal and State agencies. Categories of offstream water use include public supply, domestic, commercial, industrial, mining, irrigation, livestock, and thermoelectric power generation. Total offstream water use from groundand surfacewater sources was estimated to be about 1,225 million gallons per day (Mgal/d) in 1997 for the study area, of which ground water supplied 28 percent and surface water supplied 72 percent. Water withdrawal in coastal Georgia increased from 1,153 Mgal/d in 1980 to 1,225 Mgal/d in 1997, a 6-percent increase. During this period, surface-water withdrawal increased by 111 Mgal/d and ground-water withdrawal decreased by 38 Mgal/d.
Beyond and Within Images:A Preliminary Exploitation to Chinese Historical City Maps

This paper comprises two main parts.The first part takes an overview on Chinese historical city maps and discusses its sorts and characteristics in the historical periods based on widely literature written by former scholars.With the analysis on contemporary Chinese cartography study,the author forwards its problems and considers that the Chinese historical maps are kind of image with ideologies.The second part focuses on the relationship hetween maps and cities.From a perspective of urban planning and architecture,this paper points out the roles that different kinds of ancient city maps can be played in the study of urban image,urban inner structure and regional urban structure respectively.Finally,this paper stresses on the combination of literature with ancient maps,quantitative analysis based on the data of historical cities,and application of GIS to achieve creative results in the study of historical city.
Genomic characterization of developmental and adaptation genes: insights into vertebrate evolution

In this thesis molecular evidences related with the adaptive evolution of vertebrates are presented. In the first part, we studied the retinoid X receptors (RXR), rhodopsin 1 (RH1) and superoxide dismutases (SOD) and the results highlighted adaptive evolution as an important mechanism during the evolution of these essential development and adaptation related vertebrate genes. In the second part of the thesis, evidence is provided on how adaptive evolution may influence teleost fish radiations, namely with studies of the evolutionary diversification of 34 lateral line development genes, and two detailed case studies on the radiations of the endangered red lined torpedo barbs and the malabar snakehead fish, both endemic to the Western Ghats of India.
