Analysis of Factors Influencing the Urban Carrying Capacity of the Shanghai Metropolis Based on a Multiscale Geographically Weighted Regression (MGWR) Model

With the rapid development of urban economy and the continuous expansion of urban scale, the limitations of urban carrying capacity begin to appear. For the sustainable development of the city, more and more scholars are paying attention to the research onurban carrying capacity. Basedon the continuous research of the authors’ research group over the past ten years, this paper uses a multiscale geographically weighted regression model and method to explore the impact of geographical location, floor area ratio, public transportation, residents’ consumption level, the density of high-tech enterprises, and the ecological environment on the carrying capacity of the Shanghai metropolis. The results show that (1) the impact of geographical location on the bearing capacity decreases from downtown to the outer areas and from the northeastern area to the southwestern area of Shanghai. (2) On the whole, the elasticity of the average floor area ratio to the urban carrying capacity is 0.52%. In different regions, most of the central urban areas have exceeded the optimal average plot ratio. With an increase in the average plot ratio, the urban carrying capacity presents a downward trend. Other sample areas generally did not reach the average optimal plot ratio, especially the southwestern area of Shanghai. With an increase in the average plot ratio, the urban carrying capacity of this area improved significantly. (3) The elasticity of public transportation convenience to the urban carrying capacity is 0.23%; that is, the average increase in the urban carrying capacity is 0.23% for every 1% increase in public transportation convenience. The elasticity of residents’ consumption level is −0.18%; in other words, every 1% increase in residents’ consumption level will reduce the urban carrying capacity by 0.18% on average. The elasticity of the density of high-tech enterprises is 0.08%; hence, when the density of high-tech enterprises increases by 1%, the urban carrying capacity increases by 0.08% on average. Lastly, the elasticity of the eco-environmental status index is 0.17%; that is, every 1% increase in the eco-environmental status index increases the urban carrying capacity by 0.17% on average.

Paeniglutamicibacter terrestris sp. nov., isolated from phenanthrene-degrading consortium enriched from Antarctic soil

A novel bacterium, designated strain ANT13_2T, was isolated from a phenanthrene-degrading consortium enriched from a soil sample collected near the Great Wall Station located in the southwestern area of King George Island, Antarctica. Following a polyphasic taxonomic study, a novel species belonging to the genus Paeniglutamicibacter was described. The strain was a Gram-stain-positive bacterium that exhibited a rod–coccus growth cycle. Strain ANT13_2T grew aerobically at an optimum temperature of 20–25 °C and at pH 7.0–8.0. Ribose, arabinose and glucose were detected as whole-cell sugars. The predominant menaquinone was MK-9. The diagnostic phospholipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified phospholipid. The predominant cellular fatty acids were anteiso-C15 : 0 (67.7 %) and anteiso-C17 : 0 (11.2 %). The DNA G+C content of the genomic DNA was 60.6 mol%. Based on 16S rRNA gene sequence analysis, strain ANT13_2T showed the highest similarities to Paeniglutamicibacter antarcticus SPC26T (98.9 %) followed by Paeniglutamicibacter gangotriensis Lz1yT (98.4 %), Paeniglutamicibacter sulfureus DSM 20167T (98.3%) and Paeniglutamicibacter kerguelensis KGN15T (97.9 %). The average nucleotide identity values between strain ANT13_2T and the type strains of P. antarcticus SPC26T and P. gangotriensis Lz1yT were 73.8 and 77.5 %, respectively, which are well below the 95–96 % species circumscription threshold. On the basis of this polyphasic taxonomic study, strain ANT13_2T is proposed to represent a novel species to be named Paeniglutamicibacter terrestris sp. nov. The type strain is ANT13_2T (=TBRC 11756T=NBRC 114615T).

New evidence of metallurgical production during the Ptolemaic period in the ancient harbor of Berenike (Eastern Desert) in Egypt

This paper tries to explain the first results obtained on trench 102, located on the southwestern area of the ancient harbour of Berenike. Chronologically the trench runs from the Late Hellenistic to Roman Period, showing different uses of this area during Antiquity. Some of the data recovered are quite interesting in order to understand the evolution of this scarcely known area of Berenike’s harbor. The identification of a metallurgical furnace related to the Late Hellenistic Period is especially remarkable, as it provides some insights about the structure of this zone under the last Ptolemaic rulers. So, the main objective of the paper is to offer new data about the productive structure of this site during the Ptolemaic period with special focus on the metallurgical production.

Therapeutic Interventions with Israeli Children Exposed to Continuous Traumatic Stress of Political Violence

This chapter reviews theoretical and clinical issues related to living under continuous traumatic stress (CTS) due to exposure to political violence. Through an analysis of CTS experienced by the residents of the southwestern area of Israel, the chapter presents an approach to therapeutic interventions for children and families that advocates the adaptation of extant therapies to the CTS situation. An illustrative case study is presented, and the effect of external threat on the therapeutic relationship between therapist and client is discussed. The chapter concludes with recommendations for therapy with children who are exposed to CTS and suggestions for future research for assessing interventions of the kind described in this chapter.

Spring and autumn phenology in sub-mesothermal beech stands from the southwestern extremity of the Carpathians

The research carried out was aimed to assessing the phenological behavior of beech (Fagus sylvatica L.) in the southwestern area of the Carpathians, in submesothermal forest sites, differentiated from the majority mesothermal ones of this species. The data obtained may be used for predicting the phenological changes of the species, especially in the Carpathian area, under the future influence of expected climate change. Assessments for spring and autumn phenology (buds burst -BB and foliation, flowering and leaves senescence) were carried out on a transect with a difference in altitude of 1000 meters, in phenological research areas located at 200 m, 700 m and 1200 m. At each altitude level, 100 trees of I and II Kraft classes were phenologically characterized: 50 trees on the south-facing slope (sunny exposure) and 50 on the north-facing slope (shade exposure).The phenological data were interpreted in relation to climate data recorded in each area by a HOBO U23 Pro v2 sensor. The site conditions of submesothermal climate in the low altitude area led to DOY (day of the year) values below 100. The phenological differentiation of populations is evident in relation with the altitude, while at the same altitudinal level the influence of the exposure was much lower. The gradiental values by altitude sectors highlighted the nonlinearity of the development of foliation phenophase, the value being lower in the first 500 m, where the beech is under the impact of the submesothermal climate. It has been proven both the dependence of the foliation onset depending on the cumulation of temperatures in relation to the DOY moment and also on the values recorded throughout the vegetative rest. The altitudinal gradiental values resulting for flowering in the first and second altitudinal half of transect also differentiate the stands, but are lower than that resulting for BB. The leaves senescence has a delay of 1.8 up to 2.4 days per 100 meters altitude, and the length of the vegetation season is reduced more sharply in the upper half of the analyzed altitudinal transect. The sub-mesothermal climate could be involved in condensation of spring phenophases in the stands of the lower half of the researched area. Our data may be used for predicting the phenological changes, especially in the Carpathian area, under the expected climate change.

AGE SPAN FORMATION IN GRANITOIDS OF UKRAINIAN SHIELD

The paper discusses Berdychiv type granitoids that have always stirred up interest among researchers of the Ukrainian Shield. These rocks include minerals that are uncharacteristic of granites - cordierite, sillimanite, andalusite - and are closely related to rocks of the supposed substratum. At the same time, there still remain questions about the genetic nature of Berdychiv granites. Despite the fact that most researchers treat these granites as intrusive (anatectic) formations, there are other concepts according to which these granites are considered to be the products of metasomatic transformation (magmatic replacement) of primarily argillaceous and marly series of substratum. The Stryzhavka open pit, which is located in the Upper Bug region of the Ukrainian Shield displays differently cataclised porphyry-like plagiogranitoids (predominantly, garnet-bearing varieties in its southwestern area, locally rock-forming potassic feldspar varieties), and garnet-bearing leucocratic granites similar to those of Berdychiv type granites. The monazites of biotite-garnet granodiorite and biotite-garnet granite were dated by uranium-lead (U-Pb) isotopic dating method. The monazite of granodioritеs is dated 2049,3±3,5 million years based on the upper intersection of concordia with discordia. Significantly lower values of age (about 15 million years younger) for the monazite selected from granite, approximating 2035,1±1,9 million years were established. We assume it to be caused by prolonged crystallization of granitic melt and rather early crystallization of more basiс granodioritic magma in comparison with granitic one. Thus, the duration of the granitoid formation uncovered in the Stryzhavka open pit exceeds 15 million years, which correlates accurately with the estimates for occurrence duration of the granitic melts, which gave rise to various granites of the Ukrainian Shield.

A Method of Population Spatialization Considering Parametric Spatial Stationarity: Case Study of the Southwestern Area of China

Population is a crucial basis for the study of sociology, geography, environmental studies, and other disciplines; accurate estimates of population are of great significance for many countries. Many studies have developed population spatialization methods. However, little attention has been paid to the differential treatment of the spatial stationarity and non-stationarity of variables. Based on a semi-parametric, geographically weighted regression model (s-GWR), this paper attempts to construct a novel, precise population spatialization method considering parametric stationarity to enhance spatialization accuracy; the southwestern area of China is used as the study area for comparison and validation. In this study, the night-time light and land use data were integrated as weighting factors to establish the population model; based on the analysis of variables characteristics, the method uses an s-GWR model to deal with the spatial stationarity of variables and reduce regional errors. Finally, the spatial distribution of the population (SSDP) of the study area in 2010 was obtained. When assessed against the traditional regression models, the model that considers parametric stationarity is more accurate than the models without it. Furthermore, the comparison with three commonly-used population grids reveals that the SSDP has a percentage error close to zero at the county level, while at the township level, the mean relative error of SSDP is 33.63%, and that is >15% better than other population grids. Thus, this study suggests that the proposed method can produce a more accurate population distribution.
