Agglomeration of ZnS nanoparticles without capping additives at different temperatures
Authors: Praus Petr , Dvorský Richard , Kovář Petr , Svoboda Ladislav 
Published: December 2013

Abstract
ZnS nanoparticles were precipitated in diluted aqueous solutions of zinc and sulphide ions without capping additives at a temperature interval of 0.5–20°C. ZnS nanoparticles were arranged in large flocs that were disaggregated into smaller agglomerates with hydrodynamic sizes of 70–150 nm depending on temperature. A linear relationship between hydrodynamic radius (R
a) and temperature (T) was theoretically derived as R
a =652 - 2.11 T.
The radii of 1.9–2.2 nm of individual ZnS nanoparticles were calculated on the basis of gap energies estimated from their UV absorption spectra. Low zeta potentials of these dispersions of −5.0 mV to −6.3 mV did not depend on temperature. Interactions between individual ZnS nanoparticles were modelled in the Material Studio environment. Water molecules were found to stabilize ZnS nanoparticles via electrostatic interactions.

Authors: Giurcan Venera , Razus Domnina , Mitu Maria , Oancea Dumitru 
Published: December 2013

Abstract
The structure of premixed free one-dimensional laminar ethane-air flames was investigated by means of numerical simulations performed with a detailed mechanism (GRI-Mech version 3.0) by means of COSILAB package. The work provides data on ethane-air mixtures with a wide range of concentrations ([C2H6] = 3.0–9.5 vol.%) at initial temperatures between 300 and 550 K and initial pressures between 1 and 10 bar. The simulations deliver the laminar burning velocities and the profiles of temperature, chemical species concentrations and heat release rate across the flame front. The predicted burning velocities match well the burning velocities measured in various conditions, reported in literature. The influence of initial concentration, pressure and temperature of ethane-air mixtures on maximum flame temperature, heat release rate, flame thickness and peak concentrations of main reaction intermediates is examined and discussed.

Authors: Harsa Teodora , Harsa Alexandra , Szefler Beata 
Published: December 2013

Abstract
A novel QSAR approach based on correlation weighting and alignment over a hypermolecule that mimics the investigated correlational space was performed on a set of 40 caffeines downloaded from the PubChem database. The best models describing log P and LD50 values of this set of caffeine derivatives were validated against the external test set and in a new predictive model by using clusters of similarity.
Note on group distance magic complete bipartite graphs
Authors: Cichacz Sylwia 
Published: December 2013

Abstract
A Γ-distance magic labeling of a graph G = (V, E) with |V| = n is a bijection ℓ from V to an Abelian group Γ of order n such that the weight $$w(x) = \sum\nolimits_{y \in N_G (x)} {\ell (y)}$$ of every vertex x ∈ V is equal to the same element µ ∈ Γ, called the magic constant. A graph G is called a group distance magic graph if there exists a Γ-distance magic labeling for every Abelian group Γ of order |V(G)|.
In this paper we give necessary and sufficient conditions for complete k-partite graphs of odd order p to be ℤp-distance magic. Moreover we show that if p ≡ 2 (mod 4) and k is even, then there does not exist a group Γ of order p such that there exists a Γ-distance labeling for a k-partite complete graph of order p. We also prove that K
m,n is a group distance magic graph if and only if n + m ≢ 2 (mod 4).
The Making of Hobo Masculinities
Authors: Tapley Heather 
Published: December 2013

Abstract: The following article summarizes several discursive productions of the US hobo in the late nineteenth and early twentieth centuries in order to expose the role the hobo played historically in the making of idyllic American manhood. After the crash of the railroad boom in 1873, the hobo was produced as other to dominant ideals of masculinity that were based in a stable work ethic. Deemed a “tramp” who refused to work, the hobo became a site for medical investigations that highlighted his lack of reason, feminizing the male hobo-tramp and buttressing ideals of both bourgeois and working-class masculinities in the process. Self-identified hobos worked to counter such discourses, but in doing so, also employed exclusionary tactics to distance women, tramps, and men of colour from definitions of hobo masculinity, revealing that white masculinity represented a possession in need of protection, regardless of class.
Impact of improved documentation on an academic neurosurgical practice
Authors: Zalatimo Omar , Ranasinghe Moksha , Harbaugh Robert E. , Iantosca Mark 
Published: December 2013

Object
Accuracy in documenting clinical care is becoming increasingly important; it can greatly affect the success of a neurosurgery department. As patient outcomes are being more rigorously monitored, inaccurate documentation of patient variables may present a distorted picture of the severity of illness (SOI) of the patients and adversely affect observed versus expected mortality ratios and hospital reimbursement. Just as accuracy of coding is important for generating professional revenue, accuracy of documentation is important for generating technical revenue. The aim of this study was to evaluate the impact of an educational intervention on the documentation of patient comorbidities as well as its impact on quality metrics and hospital margin per case.

Methods
All patients who were discharged from the Department of Neurosurgery of the Penn State Milton S. Hershey Medical Center between November 2009 and June 2012 were evaluated. An educational intervention to improve documentation was implemented and evaluated, and the next 16 months, starting in March 2011, were used for comparison with the previous 16 months in regard to All Patient Refined Diagnosis-Related Group (APR-DRG) weight, SOI, risk of mortality (ROM), case mix index (CMI), and margin per discharge.

Results
The APR-DRG weight was corrected from 2.123 ± 0.140 to 2.514 ± 0.224; the SOI was corrected from 1.8638 ± 0.0855 to 2.154 ± 0.130; the ROM was corrected from 1.5106 ± 0.0884 to 1.801 ± 0.117; and the CMI was corrected from 2.429 ± 0.153 to 2.825 ± 0.232, and as a result the average margin per discharge improved by 42.2%. The mean values are expressed ± SD throughout.

Conclusions
A simple educational intervention can have a significant impact on documentation accuracy, quality metrics, and revenue generation in an academic neurosurgery department.
Effects of CO2 on the tolerance of photosynthesis to heat stress can be affected by photosynthetic pathway and nitrogen
Authors: Dan Wang  , Heckathorn Scott A. , Hamilton E. William , Frantz Jonathan 
Published: December 2013

• Premise of the study: Determining effects of elevated CO2 and N on photosynthetic thermotolerance is critical for predicting plant responses to global warming.• Methods: We grew Hordeum vulgare (barley, C3) and Zea mays (corn, C4) at current or elevated CO2 (370, 700 ppm) and limiting or optimal soil N (0.5, 7.5 mmol/L). We assessed thermotolerance of net photosynthesis (Pn), photosystem II efficiency in the light (Fv′/Fm′), photochemical quenching (qp), carboxylation efficiency (CE), and content of rubisco activase and major heat‐shock proteins (HSPs).• Key results: For barley, elevated CO2 had no effect on Pn, qp, and CE at both high and low N and only a positive effect on Fv′/Fm′ at high N. However, for corn, Pn, Fv′/Fm′, qp, and CE were decreased substantially by elevated CO2 under high and low N, with greater decreases at high N for all but qp. The negative effects of high CO2 during heat stress on photosynthesis were correlated with rubisco activase and HSPs content, which decreased with heat stress, especially for low‐N corn.• Conclusion: These results indicate that stimulatory effects of elevated CO2 at normal temperatures on photosynthesis and growth (only found for high‐N barley) may be partly offset by neutral or negative effects during heat stress, especially for C4 species. Thus, CO2 and N effects on photosynthetic thermotolerance may contribute to changes in plant productivity, distribution, and diversity in future.
De président à empereur : Louis-Napoléon Bonaparte dans Le Journal pour rire
Authors: Feudo Michela Lo 
Published: December 2013

Fondé par Charles Philipon comme feuille non politique, Le Journal pour rire se heurte bientôt à la nécessité de commenter les événements de 1848. Si les journées de février ont conservé de faibles traces dans les pages de la revue, c’est lors des élections présidentielles que les dessinateurs aiguisent leurs crayons. Le premier président de la République élu par le peuple, Louis-Napoléon Bonaparte, devient ainsi la tête de turc au sein d’une production, de plus en plus engagée et fortement symbolique qui construit son propre langage visuel entre manipulation de thèmes traditionnels et innovations formelles dues à la créativité de dessinateurs talentueux et provocateurs. En analysant le rapport entre processus historiques et procédés graphiques, il s’agira de montrer les spécificités des dessins sur « le prince-président » et la manière dont les caricaturistes se servent d’un tel personnage pour faire éclater les paradoxes et les incohérences d’un pouvoir politique qui, tout en tirant profit des révoltes républicaines, multiplie les clins d’œil au passé impérial.
De de Gaulle à Mitterrand : l'assaut de Charlie Hebdo (1969-1982)
Authors: Mazurier Stéphane 
Published: December 2013

Journal satirique, pratiquant un humour noir autoproclamé « bête et méchant » dans la lignée de son « grand frère Hara-Kiri », Charlie Hebdo a, durant ses treize années d’existence, exercé sa verve sarcastique et provocatrice à l’endroit des quatre chefs de l’État qui se sont succédé au cours de la période. Publication de gauche, le journal s’est montré le plus féroce envers les trois présidents de droite : de Gaulle est représenté en souverain mégalomane d’un autre temps, Pompidou en tyran débonnaire et Giscard d’Estaing en monarque hautain. À travers la figure présidentielle, ce sont les valeurs de droite qui sont attaquées, moquées et tournées en dérision : la monarchie républicaine qu’est la V e République fait du chef de l’État la cible privilégiée des polémistes de Charlie Hebdo . En revanche, l’élection de François Mitterrand à la présidence de la République ainsi que les premières mesures du septennat suscitent souvent l’enthousiasme, du moins le soutien, du journal, qui voit ainsi sa position d’organe contestataire du pouvoir être remise en cause.

The results include the following: (1) If TWO has a winning strategy in theMenger game on a regular spaceX, thenXis an Alster space. (2) If TWO has a winning strategy in the Rothberger game on a topological spaceX, then theGδ-topology onXis Lindelöf. (3) The Menger game and the compact-open game are (consistently) not dual.
Historical Sense as Vice and Virtue in Nietzsche's Reading of Emerson
Authors: Zavatta Benedetta 
Published: December 2013

ABSTRACT
Nietzsche was an avid reader of Emerson's essays, and their influence is discernible from his earliest philosophical writings through to his final philosophical works. Nietzsche's copies of Emerson's books are covered with traces of his reading, from underlinings, exclamation marks, question marks, and dog-eared pages to numerous annotations and philosophical comments written in the margins. I use some of these to analyze the influence Emerson exerted on Nietzsche's conception of history and historiography. The two authors can be considered “twin souls” in that they both praised the strengthening effects of past greatness and, at the same time, opposed psychological subjugation or fanaticism. Nevertheless, they were not twin minds: Nietzsche rejected Emerson's metaphysical concept of an Oversoul and turned it into the ideal of a Dionysian soul, which aims at reliving the history of humanity in order to increase its power.
Morality Makes Me Sick: A Criticism of Brian Leiter's Treatment of Health in Nietzsche
Authors: Dunkle Ian D. 
Published: December 2013

ABSTRACT
In this article, the author offers a reconstruction and criticism of Brian Leiter's interpretation of Nietzsche's criticism of conventional morality in Nietzsche on Morality. Leiter's interpretation is said to falter because it attributes to Nietzsche an implausible combination of positions. First, Nietzsche is said to be a value antirealist. But he is also said to defer to the value of the flourishing of his audience, who are limited to a certain subset of “higher” humans. The author argues that, in spite of Leiter's attempt to defend this view, he ultimately fails to explain how Nietzsche can be confident in the normative force of the higher humans' flourishing and, so, his criticism of morality. Since the author takes the problems of Leiter's reading to bear on a prevalent general reading of Nietzsche, the author concludes with a brief sketch of a plausible alternative.
Nietzsche, Naturalism, and the Tenacity of the Intentional
Authors: Alfano Mark 
Published: December 2013

ABSTRACT
Nietzsche's most insightful contribution to the naturalistic project in philosophical psychology is not methodological but substantive: he discovered an important truth about the dynamics of psychological states, which I here dub the tenacity of the intentional. According to the tenacity thesis, when an intentional state loses its object, a new object replaces the original; the state does not disappear entirely. This interpretation is supported by and helps to tie together the three essays of the Genealogy. The article concludes by contextualizing the tenacity thesis within Nietzsche's doctrine of the will to power.
“To the other side of home where the lights are given”
Authors: Heavilin Barbara A. 
Published: December 2013

Abstract
In America and Americans John Steinbeck defines his country and its people, in the process serving as a national bard, or seer—upbraiding his nation for its failures and foibles and peering into its future with both hope and some trepidation. He acknowledges the country's lapses, while praising its resilience: “We have failed sometimes, taken wrong paths, paused for renewal, filled our bellies and licked our wounds; but we have never slipped back—never” (205). The somewhat wistful tone of “we have never slipped back” lacks the confidence that “we shall never slip back” would have indicated (emphasis added). Increasingly concerned with America's mores and morality, there is throughout America and Americans an appeal to a higher self and a higher way, but no direct appeal to God, even peripherally. That appeal is reserved for a fictional account of one representative Every American, Ethan Allen Hawley, in The Winter of Our Discontent, a novel that parallels Steinbeck's concerns for his country in his non-fiction America and Americans. Part One centers around the biblical Easter story, and Part Two, focuses on the time around the Fourth of July, concluding with Ethan's oration on “light” as he contemplates suicide, with its implication that there is a Light Giver in a world beyond this one—a place he calls “home.”

<p>Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region). </p><p>We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods.</p><p>The most commonly collected plants are wild vegetables: <em>Cichorium intybus</em>, <em>Foeniculum vulgare</em>, <em>Sonchus oleraceus</em>, <em>Asparagus acutifolius</em>, <em>Papaver rhoeas</em>, <em>Rumex pulcher</em>, <em>Daucus carota</em>, <em>Allium ampeloprasum</em> and <em>Silene latifolia</em>.</p>

DOI: 10.5902/198346598808 A discussion around the application of the social network analysis methodology has being helped to understand the social dynamic operation of organizations, including governments, which are subject to different management structures that have a high degree of functional hierarchy. This study was developed in a Federal School Institution in Sao Paulo State – Brazil searching to identify the link developed between Institution administrative support staff members and their social networks. The research objective is to establish a comparison between the link data facts with Social Networks Theories which says that the more ties (contacts) exist in an informal group, the more the network promotes an open environment for exchanging knowledge and information. The research looked forward to identify how do the social networks are developed, how common objectives and subjects turns people closely connected, how do the focal points and main contacts emerge from this community and what are their influences in the rest of the group. It was applied social network measurement methodologies, combined with qualitative instrument analysis. As a conclusion, was found that the informal structure has influence over the formal structure providing an environment for exchanging knowledge and information, pointing out that some characters are actually responsible for the dynamic of networks, occupying driver and strategic position that gives them recognition as such by the other agents in the net.

DOI: 10.5902/198346598850 The strategizing is a theoretical approach that includes the implementation of strategies by connecting the practice performed by practitioners who have types of behaviors driven by social practices (Jarzabkowski et al., 2007). The aim of this study was to determine how the strategy is developed in practice for the recognition of an undergraduate degree at MEC. For both: (i) identify the strategic practices adopted in the organization, (ii) verify how the practice happens at different organizational levels and (iii) analyze how practitioners participating in the strategy as practice. The research approach is qualitative. The study was conducted in a private college of character located in northern Paraná. We used a semi-structured interview structured with open questions, document analysis and observation, and data collection techniques, providing triangulation of data collected. For the data analysis we adopted the technique Exam Pattern of Behavior (PÉREZ-AGUIAR, 1999). The results highlight the need for alignment between the three elements developed in the work Jarzabkowski et al. (2007), and emphasize the existence of the axis of environmental management across the entire line as pedagogical courses offered, as a requirement of MEC.

DOI: 10.5902/198346598892 The Social balance sheet is an accounting report that highlights the environmental and socio-economic relations. The objective of this research is to check the relationship between net revenue and Environmental indicators extracted from the Social balance sheets published by the companies of the corporate sustainability index BMFBOVESPA, in the period from 2007 to 2010. For both, it was found-Environmental Indicators using the Social balance sheet to verify participation in net revenues of the companies surveyed. The methodology was characterized as descriptive, through desk research and quantitative approach. With respect to the results, it was found that companies have positive correlation between net (RL) and the internal social indicators (ISI) and external (ISE), environmental indicators (IA), amount of Employees (QF) and number of employees with special needs (QFNE), and the higher the value of net revenues increased participation in the value of these indicators. In general analysis, it was found that the Environmental Indicators correlate positively with net revenue, so that companies with higher value in net revenues also had the highest values in the searched Indicators.
Refining the relationship between lightning and convective rainfall over the ocean
Authors: Stolz Douglas C. , Businger Steven , Terpstra Annick 
Published: December 2013

AbstractThe lightning stroke density observed by Vaisala's Global Lightning Dataset (GLD360) was compared to maximum reflectivity in the upper and lower troposphere observed by NASA's Tropical Rainfall Measuring Mission Precipitation Radar over remote oceanic regions. We found that GLD360 stroke density is strongly correlated with maximum reflectivity above 0°C and the height of the 30 dBZ isopleth in two ocean basins (best represented by a logarithmic least squares regression). The maximum reflectivity above 0°C increases ~8–10 dBZ and the maximum height of the 30 dBZ isopleth increases ~2.8–3.8 km across the domain of stroke density. Stroke density and the maximum near‐surface reflectivity are also correlated, but the range of the resulting logarithmic relationship is less than that found for maximum reflectivity above 0°C. There is high confidence in the logarithmic regressions as R2 values are generally above 0.9 during the study. A bootstrap resampling approach confirms that the lightning versus rainfall relationship is statistically significant. Vertical profiles of radar reflectivity show that progressively larger values of stroke density are associated with higher reflectivity at most altitudes (most pronounced near 6.5 km mean sea level) and less rapid decreases in reflectivity with increasing height above 0°C. The logarithmic relationships between lightning and rainfall defined in this study have significant utility in creating proxy data sets, such as pseudoreflectivity, for weather analysis and assimilation in numerical weather prediction.
