Are Chinese Cities Too Small

This paper models and estimates net urban agglomeration economies for cities. Economic models of cities postulate an inverted U shape of real income per worker against city employment, where the inverted U shifts with industrial composition across the urban hierarchy of cities. This relationship has never been estimated, in part because of data requirements. China has the necessary data and context. We find that urban agglomeration benefits are high—real incomes per worker rise sharply with increases in city size from a low level. They level out nearer the peak and then decline very slowly past the peak. We find that a large fraction of cities in China are undersized due to nationally imposed, strong migration restrictions, resulting in large income losses. Copyright 2006, Wiley-Blackwell.
Simulação da dinâmica de nutrientes no trato gastrintestinal: aplicação e validação de um modelo matemático para bovinos a pasto

ABSTRACT - The objective of the present work was to validate the ruminal and post-ruminal nutrient dynamics and the ruminalmicrobial growth predictions, by using the equations of the Cornell system. The experiment was carried out during the rainy and dry seasonsof the 1996 year, in a natural pasture area situated in the county of Vicosa (MG). Esophageally, ruminally and abomasally cannulated steerswere used during two experimental periods within each season, and external markers (Cr 2 O 3 and Eu) were used to estimate the intake andthe ruminal digesta passage rate. The total nitrogen and the bacterial nitrogen flows, total and structural carbohydrates digested in the rumen,and the total of digestible nutrients contents were determined. These variables were also predicted from the model described in the Cornell system to validate its estimates. It was verified that the model was sensitive to the passage rate estimates, overestimated (12.38%) thebacterial nitrogen flow to the abomasum, and underestimated (70.64%) the structural carbohydrates availability in the rumen.

Topic extraction from adverbial clauses

This paper offers new data to support findings about Topic extraction from adverbial clauses. Since such clauses are strong islands, they should not allow extraction of any kind, but we show here that if the appropriate conditions are met, Topics of the CLLD kind in Romance can move out of them. We propose that two conditions must be met for such movement to be possible: the first is that the adverbial clause must have undergone topicalisation in the first place; the second is that the adverbial clause is inherently topical from a semantic viewpoint. Contrast with other language families (Germanic, Quechua and Japanese) is provided and the semantic implications of the proposal are briefly discussed. Keywords: topicalisation; Clitic Left Dislocation; syntactic islands; adverbial clauses Este articulo ofrece nuevos datos sobre la extraccion de Topicos desde oraciones subordinadas adverbiales. Dado que dichas oraciones son islas fuertes, no deberian permitir extraccion de ningun tipo, pero mostramos que si se dan las condiciones apropiadas, los Topicos del tipo CLLD en lenguas romanicas pueden desplazarse fuera de ellas. Proponemos que se deben cumplir dos condiciones para que ese movimiento sea posible: la primera es que la propia subordinada adverbial se haya topicalizado en primer lugar; la segunda es que la subordinada adverbial sea inherentemente un Topico desde el punto de vista semantico. Proporcionamos tambien algunos contrastes con otras familias linguisticas (germanica, quechua y japones) y se discuten brevemente las implicaciones semanticas de la propuesta. Palabras clave: topicalizacion; dislocacion a la izquierda con clitico; islas sintacticas; oraciones adverbiales
An Experimental Study On Spalling Of High Strength Concrete Elements Under Fire Attack

The spalling of high strength concrete under f i e attack is discussed in this paper. Two series of f i e tests on reinforced concrete elements were carried out in order to investigate the spalling behavior and effect of spalling on the fire endurance of reinforced concrete elements. The results of the f i e tests on 30 specimens can be summarized as follows: a) the spalling is significantly affected by the water-cement ratio of the concrete, the permeability of the concrete, the amount of steel reinforcement, the f i e intensity and the age of the concrete at f i e exposure, b) the addition of polypropylene fiber into concrete is a good measure for the prevention of spalling and can improve the f i e endurance of reinforced concrete elements, c) the addition of polypropylene fiber into concrete at a ratio of Ikg polypropylene fiber per lm3 concrete reduces the depth of spalling by about 18mrn.

Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs

AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. However, the aromatic/arginine (ar/R) selectivity filter and theproposed substrate specificity of XIPs resemble that of some NIPs aquaporinisoforms. The aim of the studies in this thesis was to functionally and structurallycharacterize Nicotiana benthamiana XIP1;1s and Arabidopsis thaliana NIP1;1 andNIP5;1 aquaporins.By using the Pichia pastoris expression system, NbXIP1;1s, AtNIP1;1 andAtNIP5;1 were successfully expressed. NbXIP1;1s and AtNIP5;1 increased thesensitivity of P. pastoris cells to boric acid. Furthermore, the N-terminally His-taggedsplice-variant NbXIP1;1α appeared more opened to boric acid than the C-terminallyHis-tagged protein when expressed in P. pastoris. In P. pastoris spheroplasts, differences in water and glycerol permeability of NbXIP1;1α and AtNIP5;1 were observed. AtNIP5;1 was permeable to water and glycerol but NbXIP1:1α was impermeable to both substrates. NbXIP1;1α and AtNIP5;1 proteins were purified by Ni-NTA affinity chromatography. While the yield obtained for NbXIP1;1α was adequate for both functional and initial crystallization studies, the initial yield for AtNIP5;1 was only sufficient for functional characterization. The current purification scheme for AtNIP5;1 needs to be optimized to obtain sufficient amounts of protein for a comprehensive crystallization study.In a stopped-flow spectrometric analysis, NbXIP1;1α was partially permeable toboric acid in proteoliposomes. Mass spectrometric analysis revealed that thepurified NbXIP1;1α protein was phosphorylated at five amino acid residues in theN-terminal region. Results from mutational studies suggested that NbXIP1;1α maybe regulated by its N-terminal domain. It was therefore proposed that NbXIP1;1α isgated by phosphorylation. By site-directed mutagenesis, it was shown that singleamino acid substitutions L79G in helix 1 and I102H in helix 2 were sufficient torender NbXIP1;1α water permeable. Water permeable NbXIP1;1α mutants offer ameans to further probe the functional properties of NbXIP1;1α. Homology modelsof wild-type and mutant NbXIP1;1α in conjunction with functional studies suggested that T246 is the residue at the helix 5 position in the ar/R filter of NbXIP1;1α. The models also revealed a previously unrecognized orientation and interaction of the conserved arginine in the ar/R filter, which could serve as a novel guide to tune the selectivity of aquaporins.
Chronotypen in Beziehungen

In der Literatur werden verschiedene Geschlechtsunterschiede im Chronotypus berichtet, die sich über die Lebensspanne hinweg verändern. In Beziehungen können starke Unterschiedlichkeit in der Tageszeitpräferenz sowie andere schlafbezogene Parameter weit reichende Konsequenzen, etwa für das Sexualleben, mit sich bringen, die jedoch bisher nicht ausreichend untersucht wurden.
Do Workers Pay for Social Protection? An Analysis of Wage Differentials in the Egyptian Private Sector

This paper examines whether private employers are able to pass the cost of protective social regulations to their workers in the form of lower wages. I answer this question by decomposing wage differentials between protected and unprotected workers into components explained by differences in observable characteristics and unobserved heterogeneity and an unexplained component. I conclude that, while there are positive compensating differentials for employment instability and work outside fixed establishments, unprotected workers are not compensated for the lack of social protection. In fact, protected workers appear to receive positive wage premia, primarily in the form of higher returns on their human capital. I also find that the additional cost of female-specific protections is not passed on to protected female workers in the form of lower wages, suggesting that it may instead limit female employment in that sector.
Serum and Urinary Nitrites and Nitrates and Doppler Sonography in Detection of Early Diabetic Complications

Objective: to evaluate serum and urinary nitrite and nitrate concentrations as an index of nitric oxide (NO) production in type1diabetes mellitus (T1DM) and to investigate the possible alteration and correlation with intra renal Doppler resistive indexes (RIs). Design: The study included 90 children and adolescent with T1DM divided into 2 groups: Group 1: included 45 prepubertal type1 diabetics who were defined as Tanner stage1. Their age ranged between 8-14 years. Group 2: included 45 pubertal type diabetics who were defined as Tanner stages 2-5. Their ages ranged between 15-19 years. They were compared to 45 age and sex matched healthy controls. Clinical examination was done. Laboratory investigations included; post-prandial blood glucose (PPBG), glycosylated heamoglobin (HbA1C), Fundus examination, urinary microalbumin and measurement of serum and urinary nitrite and nitrate levels. Doppler ultrasonographic registration of intrarenal RIs were performed. Results: Compared to controls, both diabetic groups had significantly increased concentrations of serum (P=0.001) and urinary NO (P=0.008). Doppler RIs values were significantly elevated in both diabetic groups compared to controls (P<0.001). A significant positive correlation was found between serum and urinary NO levels (P<0.001). Serum NO was positively correlated with Doppler RIs (P=0.002), HbA1c (P=0.012), PPBG (P=0.000) and diabetes duration (P=0.004). Doppler RIs were positively correlated with mean HbA1c (P=0.025), PPBG (P=0.001) and diabetes duration (P=0.000). Conclusion: In type 1 diabetes chronic hyperglycemia may act through a mechanism that involves increased NO production or action and contributes to generating intrarenal hemodynamic abnormalities which could be detectable by Doppler ultrasonography even before overt clinical nephropathy. Further follow up studies are needed to document the usefulness of Doppler ultrasound in detection of preclinical nephropathy.
The Volatility Trap : E ff ects on Human Capital Accumulation

This paper presents results from instrumental variable estimates of the effect of per capita GDP volatility on secondary school enrollment. For a panel of 189 countries spanning from the years 1970 through 2000, we construct five-year historical measures of rainfall volatility, and show that these are a significant predictor of per capita GDP volatility. Rainfall volatility also has a significant reduced-form effect on secondary school enrollment. Our 2SLS results suggest that per capita GDP volatility has a significant, negative effect on secondary
Relation of interpersonal relationship, clinical stress and satisfaction of clinical practice in nursing students

Purpose: In this study, the relationship between the interpersonal relationships, clinical stress and satisfaction of clinical practice among nursing was examined. Method: The participants were 261. Data collected from 7 September to 18 September 2015 were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Result: The mean scores for the interpersonal relationship (3.74±0.39), stress (3.21±0.54), and satisfaction (3.44±0.45) in clinical practice were above average. Interpersonal relationships differed significantly according to year (F=3.12, p=.046), satisfaction with nursing as a major (F=15.84, p<.001), important of interpersonal relationships (F=4.76, p=.001), and academic achievement (F=3.80, p=.011). Stress in clinical practice differed significantly according to the year (F=8.05, p<.001), application motivation (F=4.55, p=.001) and satisfaction with nursing as a major (F=2.69, p=.046). Satisfaction in clinical practice differed significantly according to satisfaction with nursing as a major (F=3.24, p=.022), important of interpersonal relationships (F=3.01, p=.019), and academic achievements (F=5.24, p=.002). Significant correlations were observed between the interpersonal relationships and satisfaction in clinical practice (r=.24, p<.001). Interpersonal relationship (β=.21, p<.001), academic achievements (β=.12, p=.045) were factors influencing satisfaction in clinical practice. Conclusion: The interpersonal relationships need to be improved to increase nursing students' satisfaction with clinical practice
A Corrected Time-Area Technique for One-dimensional Flow

Time-Area method is one of the most widely applied techniques of watershed routing, and can be potentially used as a distributed model. In this paper, a fundamental flaw in the arrangement of subareas in the original time-area histogram is identified for one-dimensional flow. This is conducted on the basis of comparing time-area hydrograph with that of the kinematic wave theorem. Accordingly, a revised time-area algorithm is developed as a substitute for the original time-area. It is proved that in the revised approach, subareas must be reversely arranged. It is also shown that the revised time-area hydrograph is in perfect agreement with the hydrograph derived by the kinematics wave theory.
Increasing Optical Performance of 8500 K , 7000 K Remote-Packaging WLEDs by α-SrO 3 B 2 O 3 : Sm 2 + Conversion Phosphor

In this paper, by mixing the αSrO·3B2O3:Sm conversion phosphor into the phosphor layer, an innovative recommendation for increasing optical performance of the white LEDs (WLEDs) with remote-packaging, which has an average correlated color temperature (CCT) of 7000K and 8500K, is proposed and demonstrated. By varying α-SrO·3B2O3:Sm concentration from 2% to 24%, the obtained results proposed that color uniformity, color rendering index (CRI), color quality scale (CQS), and luminous e cacy could be improved signi cantly. The results demonstrated a prospective recommendation for manufacturing remote-packaging WLEDs.
An Intelligent Game using stratagems based on Evolving Compute

In this research we presented the design of a strategy videogame in first person (also called FPS – First Person Shooter) where the user is the main personage. In this game two different virtual societies are modeled. One of them (denominated “civilians”) will always try to position itself near the player as protection means, while the other will try to eliminate the player as well as the civilians. The behavior of each society has been modeled by means of two different evolutionary techniques. While the behavior of civilians’ society has been implemented using technique PSO, the behavior of the society of “enemies” has been modeled using Cultural Algorithms. Keywords: Stratagem Videogame, Artificial Societies, Cultural Algorithms, FPS, Particle Swarm Optimization.

Using Irregularly Spaced Returns to Estimate Multi-factor Models: Application to Brazilian Equity Data

Abstract Multi-factor models are useful tools to explain cross-sectional covariance in equities returns. In this paper a new estimation method is proposed that makes use of irregularly spaced returns and an empirical example is provided with the 389 most liquid equities in the Brazilian Market. The market index shows itself capable of explaining equity returns while the US$/Brazilian real exchange rate and the Brazilian short interest rate do not. The example shows the usefulness of the estimation method in further using the model to fill in missing values and to provide interval forecasts.
On Resilience of Connectivity in the Evolution of Random Graphs

In this note we establish a resilience version of the classical hitting time result of Bollobás and Thomason regarding connectivity. A graph $G$ is said to be $\alpha$-resilient with respect to a monotone increasing graph property $\mathcal{P}$ if for every spanning subgraph $H \subseteq G$ satisfying $\deg_H(v) \leqslant \alpha \deg_G(v)$ for all $v \in V(G)$, the graph $G - H$ still possesses $\mathcal{P}$. Let $\{G_i\}$ be the random graph process, that is a process where, starting with an empty graph on $n$ vertices $G_0$, in each step $i \geqslant 1$ an edge $e$ is chosen uniformly at random among the missing ones and added to the graph $G_{i - 1}$. We show that the random graph process is almost surely such that starting from $m \geqslant (\tfrac{1}{6} + o(1)) n \log n$, the largest connected component of $G_m$ is $(\tfrac{1}{2} - o(1))$-resilient with respect to connectivity. The result is optimal in the sense that the constants $1/6$ in the number of edges and $1/2$ in the resilience cannot be improved upon. We obtain similar results for $k$-connectivity.
Methodology for Application Logic Recovery from Existing Systems

´´ Abstract. Newly emerging software design paradigms necessitate changes in legacy enterprise applications. For many such legacy systems their transition to the new paradigms becomes problematic or even impossible due to obsolescence of technologies they use. Replacement of the old system with the new one, built from scratch, is usually economically unacceptable. Therefore, there is a growing interest in methods for automated migration of legacy systems into a new paradigm. In this paper we propose a methodology for extraction and migration of application logic information from existing systems. The information extracted from a legacy application is stored in the form of precise requirement-level models enabling automated transformation into a new system structure. informacje s ˛ a przechowywana w postaci precyzyjnego modelu na poziomie wymagan oprogramowania, ktory nast ˛ epnie mo˙ ze poslujako ´ automatycznej transformacji do nowej struktury systemu.

TWEETS AND FACEBOOK POSTS, THE NOVELTY TECHNIQUES IN THE CREATION OF ORIGIN-DESTINATION MODELS

Abstract. Social media and big data have emerged to be a useful source of information that can be used for planning purposes, particularly transportation planning and trip-distribution studies. Cities in developing countries such as South Africa often struggle with out-dated, unreliable and cumbersome techniques such as traffic counts and household surveys to conduct origin and destination studies. The emergence of ubiquitous crowd sourced data, big data, social media and geolocation based services has shown huge potential in providing useful information for origin and destination studies. Perhaps such information can be utilised to determine the origin and destination of commuters using the Gautrain, a high-speed railway in Gauteng province South Africa. To date little is known about the origins and destinations of Gautrain commuters. Accordingly, this study assesses the viability of using geolocation-based services namely Facebook and Twitter in mapping out the network movements of Gautrain commuters. Explorative Spatial Data Analysis (ESDA), Echo-social and ArcGis software were used to extract social media data, i.e. tweets and Facebook posts as well as to visualize the concentration of Gautrain commuters. The results demonstrate that big data and geolocation based services have the significant potential to predict movement network patterns of commuters and this information can thus, be used to inform and improve transportation planning. Nevertheless use of crowd sourced data and big data has privacy concerns that still need to be addressed.
USE OF SUCCESSIONAL HABITAT AND FRUIT RESOURCES BY SONGBIRDS DURING AUTUMN MIGRATION IN CENTRAL NEW JERSEY

Abstract We evaluated the effects of plant succession on habitat use and fruit resource availability for autumn migratory and resident songbirds in 43 ha of abandoned farm fields in central New Jersey. Using fixed net sites, standardized effort, and simultaneous sampling across habitat types, we mist-netted birds to compare habitat use and found that (1) use of three shrub-tree invasion interfaces declined as fruit-bearing shrubs were overgrown by trees, while use of three open shrublands changed little over the same period; (2) use of two pairs of contrasting successional habitats, shrubland and young woodland, was higher in the shrubland with abundant, highly nutritional fruits than in young woodland with sparse fruit; and (3) use of three shrublands at similar successional stages but with different fruit availability differed by bird taxonomic family and migratory strategy. Data on species composition and relative abundance of fruit-bearing shrubs and fruit consumption by birds (assessed by regurgitated and defecated matter) were used to elucidate avian patterns of habitat use. The relative abundance of fruit-bearing species may be more important than habitat structure in determining habitat use by birds. Shrubland dominated by panicled dogwood (Cornus racemosa) was favored over shrubland dominated by red cedar (Juniperus virginianum) or multiflora rose (Rosa multiflora). Favored vines were Japanese honeysuckle (Lonicera japonica), Virginia creeper (Parthenocissus quinquefolia), poison ivy (Toxicodendron radicans), and grape (Vitis spp.).
