Measuring the Urban Forms of Shanghai’s City Center and Its New Districts: A Neighborhood-Level Comparative Analysis

Rapid urban expansion has radically transformed the city centers and the new districts of Chinese cities. Both areas have undergone unique redevelopment and development over the past decades, generating unique urban forms worthy of study. To date, few studies have investigated development patterns and land use intensities at the neighborhood level. The present study aims to fill the gap and compare the densities of different types of developments and the spatial compositions of different commercial uses at the neighborhood level. We captured the attributes of their built environment that support instrumental activities of daily living of 710 neighborhoods centered on the public elementary schools of the entire Shanghai municipality using application programming interfaces provided in Baidu Map services. The 200 m neighborhood provided the best fit to capture the variations of the built environment. Overall, city center neighborhoods had significantly higher residential densities and housed more daily routine destinations than their counterparts in the new districts. Unexpectedly, however, the total length of streets was considerably smaller in city-center neighborhoods, likely reflecting the prominence of the wide multilane vehicular roads surrounding large center city redevelopment projects. The findings point to convergence between the city center’s urban forms and that of the new districts.
Combining Ability of New Yellow Maize Inbred Lines and Superiority of their Hybrids to Check Cultivars

Twenty five new yellow maize inbred lines were top crossed with two testers, i.e. inbred lines; Sk11 and Gz658 during 2016 season at Sakha Agric. Res. Station of Agricultural Research center (ARC), Egypt. The resulting 50 crosses along with two commercial check hybrids ( SC 162 and SC 168) were evaluated in yield trails using a randomized complete block design with four replications at Sakha and Mallawy Agric. Res. Stations (ARC) in 2017 growing season to study the combining ability of these new inbred lines and evaluated the superiority of crosses compered to commercial crosses. Mean squares due to hybrid (H), hybrid × location (H ×Loc.) were highly significant for days to 50% silking, ear position, number of ears/ plant and grain yield/ha. Also, mean squares due to line (L), tester (T) and their interaction (L × T) were significant for all studied traits except for L×T of ear position, number of ears/plant and grain yield. The best inbred line, that revealed desirable GCA effects were Sk5008/27 for earliness, Sk5010/57 for ear position, Sk5010/54 for No. of ears/plant, and Sk5008/31 for grain yield. The best hybrid superiority relative to checks was exhibited by Sk5007/27 × Sk11 for earliness, Sk5010/44 × Sk11 for ear position, Sk5010/58 × Sk11 for No. of ears/plant and Sk5008/31 × Gz658 for grain yield. The 25 inbred lines were classified into two different heterotic groups using HSGCA method for grain yield, group 1 (Sk11) included seven inbred lines and group 2 (Gz658) included seven inbred lines.
Comparative Study of Coumarin-120 (C-120) and Stilbine-3 (STB-3) Laser Dyes Doped in Sol-Gel Glasses

In 1967 the first work in solid state dye laser was performed by doping rhodamine dyes in Polymethylmethacrylate (PMMA) materials. Since then some materials like various types of polymers, co-polymers, poly composite glasses have been used as host matrices for doping different laser dyes. Polymers suffer from limited mechanical and thermal stability. Hence glasses can be the alternative hosts. However, because of high processing temperature leading to permanent destruction of dye molecules, the conventional glass preparation technique is not suitable for the introduction of organic laser dyes. This difficulty can be overcome by introducing the laser dye molecules in sol-gel glass which is prepared at low temperature. Recent work with sol-gel glasses shows that these glasses may prove to be better materials compared to polymeric materials because glasses being hard, best optically transparency in Near UV-UV and Visible region and show better photostability. In this research work we reported, comparative study of the photophysical properties of Coumarin-120 (C-120) belonging to 7-aminocoumarin family having two hydrogen atoms attached to the N atom at the 7-position, with Stilbene-3 (STB-3) in three types of HCl catalyzed SiO2 sol-gel matrices prepared by Method I, Method II and Method III respectively.
Pericoronary and periaortic adipose tissue density are associated with inflammatory disease activity in Takayasu arteritis and atherosclerosis

Abstract Aims To examine pericoronary adipose tissue (PCAT) and periaortic adipose tissue (PAAT) density on coronary computed tomography angiography for assessing arterial inflammation in Takayasu arteritis (TAK) and atherosclerosis. Methods and results PCAT and PAAT density was measured in coronary (n = 1016) and aortic (n = 108) segments from 108 subjects [TAK + coronary artery disease (CAD), n = 36; TAK, n = 18; atherosclerotic CAD, n = 32; matched controls, n = 22]. Median PCAT and PAAT densities varied between groups (mPCAT: P < 0.0001; PAAT: P = 0.0002). PCAT density was 7.01 ± standard error of the mean (SEM) 1.78 Hounsfield Unit (HU) higher in coronary segments from TAK + CAD patients than stable CAD patients (P = 0.0002), and 8.20 ± SEM 2.04 HU higher in TAK patients without CAD than controls (P = 0.0001). mPCAT density was correlated with Indian Takayasu Clinical Activity Score (r = 0.43, P = 0.001) and C-reactive protein (r = 0.41, P < 0.0001) and was higher in active vs. inactive TAK (P = 0.002). mPCAT density above −74 HU had 100% sensitivity and 95% specificity for differentiating active TAK from controls [area under the curve = 0.99 (95% confidence interval 0.97–1)]. The association of PCAT density and coronary arterial inflammation measured by 68Ga-DOTATATE positron emission tomography (PET) equated to an increase of 2.44 ± SEM 0.77 HU in PCAT density for each unit increase in 68Ga-DOTATATE maximum tissue-to-blood ratio (P = 0.002). These findings remained in multivariable sensitivity analyses adjusted for potential confounders. Conclusions PCAT and PAAT density are higher in TAK than atherosclerotic CAD or controls and are associated with clinical, biochemical, and PET markers of inflammation. Owing to excellent diagnostic accuracy, PCAT density could be useful as a clinical adjunct for assessing disease activity in TAK.
Exploratory Action Research: Teaching EFL Vocabulary to Deaf Students through the Use of Visual Aids

In Chile, the 2015 Decree 83 from the Ministry of Education demands curriculum adaptations to ensure that students with special learning needs fully develop their skills by being included into the mainstream classroom. However, little information can be found regarding deaf and hard of hearing (D/HH) students in English as a Foreign Language (EFL) classrooms. Therefore, this qualitative Exploratory Action Research (EAR) aims to explore the contribution of using visual aids in the EFL classroom for teaching written vocabulary to five D/HH students from a public school in Chile. Two multitask tests were conducted before and after the intervention to assess the performance of the students on recalling vocabulary, and a semi structured interview was carried out to identify the students’ perspectives regarding visual aids and EFL learning. While the performance test showed inconclusive results, the students’ perspectives on the use of visual aids were positive. These findings are relevant to provide insights into the challenges these students face and the importance of Sign Language and visual aids to create an effective environment for inclusive teaching practices.
The difficulty index of biology topics in Indonesian Senior High School: Biology undergraduate students’ perspectives

Biology is a subject that contains of many difficult concepts to study. This study aimed to identify Biology topics taught in Senior High School (SHS) which were considered as difficult materials by undergraduate students. The data were gathered by means of a web-based survey from 198 Biology students of 25 universities and 51 Biology education students of nine universities in Indonesia. The biology students graduated from SHSs in 97 regions/municipality, while the biology education students were graduated from 34 regions/municipality. The data were analyzed using two formulas: 1) Biology Difficulty Index (BDI) to determine the difficulty index of Biology subject, and 2) Topic Difficulty Index (TDI) to examine the difficulty index of each Biology topics. The results showed that the highest value of TDI was Genetics. There was no significant difference of BDI between Biology students and Biology education students. The lower of the students’ BDI, the higher the level of their interest in Biology subject. The primary cause of difficulty encountered by the students in studying various topics of Biology was the complicated characteristics of the materials. The findings of this study can be followed up by designing diagnostic tests and instructional designs in biology topics which consider students’ difficulty.
Distributional Effects of Monetary Policy

As central banks across the globe have responded to the COVID-19 shock by rounds of extensive monetary loosening, concerns about their inequality impact have grown. But rising inequality has multiple causes and its relationship with monetary policy is complex. This paper highlights the channels through which monetary policy easing affect income and wealth distribution, and presents some quantitative findings about their importance. Key takeaways are: (i) central banks should remain focused on macro stability while continuing to improve public communications about distributional effects of monetary policy, and (ii) supportive fiscal policies and structural reforms can improve macroeconomic and distributional outcomes.
Stratospheric Ozone and Climate Forcing Sensitivity to Cruise Altitudes for Fleets of Potential Supersonic Transport Aircraft

The possibility of commercial and business supersonic aircraft that fly in the lower stratosphere is being discussed and specific designs are under consideration. Emissions from supersonic transports have raised crucial environmental concerns regarding ozone and climate. The atmospheric response is sensitive to a range of factors regarding aircraft types, designs, and deployment parameters. This study conducts a series of sensitivity experiments of possible future cruise altitudes to evaluate the potential atmospheric response for a fleet of supersonic aircraft assumed to be fully operational in 2050. Cruise emissions in the sensitivity studies were varied in 2 km bands over the 13–23 km altitude range. We show that the supersonic aircraft can induce both ozone increase and decrease depending on altitude primarily as a result of emissions of nitrogen oxides, and the changes in total column ozone depend on the cruise altitude. The total column ozone change is shown to have a small increase flying from 13 to 17 km, with the ozone impact not very dependent on cruise altitude. As cruise altitude transitions from 17 to 23 km, the ozone impact transitions from production to depletion and the column ozone depletion strongly depends on cruise altitude. We also explore the seasonal ozone loss, changes in ozone, and climate radiative forcing per unit of fuel burn as a function of cruise altitude. The climate impact of water vapor emissions shows a larger effect associated with higher cruise altitude, with more than 1 mW m−2 Tg−1 yr for cruise altitudes above 19 km.
Content creation intention in digital participation based on identity management on Twitch

ABSTRACT Extant research lacks a systematic analysis of how creators’ content creation can be motivated in a social media-enabled platform such as Twitch. This study fills this gap by building on self-presentation theory to develop a belief-motivation-intention model. We argue that creators’ identity management and community support affect content creation and is influenced by their beliefs on self-presentation, which are characterised as self-efficacy, norms and social involvement. The results of empirical data support the proposed model. Our results have significant theoretical and managerial implications.
Response of Runoff to Extreme Land Use Change in the Permafrost Region of Northeastern China

To study the response of runoff to extreme changes in land use, the Soil and Water Assessment Tool (SWAT) model was used to construct historical, extreme, and future scenarios for several major landscape types in a permafrost region of northeastern China. The results show that the SWAT model is applicable in the Tahe River Basin; forestlands, shrublands, wetlands, and grasslands are the main land-use types in this basin, and the transfers among them from 1980–2015 have impacted runoff by less than 5%. Under extreme land use-change scenarios, the simulated runoff decreased from grasslands, to wetlands, shrublands, and finally, forestlands. The conversion of extreme land-use scenarios produces different hydrological effects. When forestland is converted to grassland, runoff increases by 25.32%, when forestland is converted to wetland, runoff increases by 13.34%, and the conversion of shrubland to forestland reduces runoff by 13.25%. In addition, the sensitivity of runoff to different land-use changes was much greater during flood seasons than in dry seasons. Compared to the reference year of 2015, the annual simulated runoff under the two future land-use scenarios (shrublands to forestlands and shrublands to wetland) was less. Also, both future land-use scenarios showed effects to decrease flooding and increased dryness, This study provided important insight into the integrated management of land use and water resources in the Tahe River Basin and the permafrost region of northeastern China.

Transitions in Technology-Mediated Cardiac Rehabilitation and Self-management: Qualitative Study Using the Theoretical Domains Framework

Background An acute cardiac incident is a life-changing event that often necessitates surgery. Although surgery has high success rates, rehabilitation, behavioral changes, and self-care are critical to long-term health. Recent systematic reviews have highlighted the potential of technology in this area; however, significant shortcomings have also been identified, particularly with regard to patient experience. Objective This study aims to improve future systems and to explore the experiences of cardiac patients during key phases after hospitalization: recuperation, initial rehabilitation, and long-term self-management. The key objective is to provide a holistic understanding of behavioral factors that impact people across these phases, understand how experiences evolve over time, and provide user-centered recommendations to improve the design of cardiac rehabilitation and self-management technologies. Methods Semistructured interviews were conducted with people who attended rehabilitation programs following hospitalization for acute cardiac events. Interviews were developed and data were analyzed via the Theoretical Domains Framework, a pragmatic framework that synthesizes prior theories of behavioral change. Results Three phases that arise posthospitalization were examined, namely, recuperation, rehabilitation, and long-term self-management. Through these phases, we describe the impact of key factors and important changes that occur in patients’ experiences over time, including the desire for and redefinition of normal life, the need for different types of formal and informal knowledge, the benefits of safe zoning and connectedness, and the need to recognize capability. The use of the Theoretical Domains Framework allows us to show how factors that influence behavior evolve over time and to identify potential sources of tension. Conclusions This study provides empirically grounded recommendations for the design of technology-mediated cardiac rehabilitation and self-management systems. Key recommendations include the use of technology to support a normal life, leveraging social influences to extend participants’ sense of normality, the use of technology to provide a safe zone, the need to support both emotional and physical well-being, and a focus on recognizing capability and providing recommendations that are positive and reinforce this capability.
Pattern Making and Pattern Breaking: Measuring Novelty in Brazilian Economics

How do new ideas emerge in academic contexts and what forces determine which ideas get selected and which are forgotten? We analyze more than 1,600 papers presented at the ANPEC Brazilian Economics Meetings from 2013 to 2019 using topic modeling and relative entropy measures. In contrast to simply counting citations or reference combinations, these methods explore the information in the actual texts to detect the rise of new patterns and whether these patterns persist once they have been established. We find that novelty is highly correlated with transience so that most new ideas are quickly forgotten. However, of the ideas that persist those that are more novel have a higher impact. We show that our text-based measure of impact is correlated with subsequent citations. Our results provide a metric to compare the nature of research at the level of Brazilian Economics departments as well as for individual researchers. Finally, we analyze how the selection procedures for the ANPEC meetings affect the incentives for economists to pursue more novel or conventional research.
Breaking down the barriers: educational paths, labour market outcomes and wellbeing of children of immigrants

ABSTRACT The goal of successfully incorporating ethnic minorities represents a decisive challenge for modern societies. However, migratory background continues to negatively affect the life trajectories of migrants’ descendants. ‘Hard’ and ‘soft’ barriers determine long-term inequality gaps and low intergenerational social mobility in both longstanding and more recent European immigration countries. This special issue complements the sparse findings on education, labour market outcome and wellbeing relating to immigrant offspring by providing original insight in order to individuate strategies for removing the obstacles that the descendants of migrants face. In-depth analyses have been performed for specific Southern European contexts in order to explore the specific inequality patterns that are emerging in these more recent and unexplored immigration contexts. The main findings suggest that the lower academic performances of immigrants’ descendants can be raised through language-support programmes, mentoring programmes, positive role and disciplinary climate, extra-scholastic activities and parental involvement. Equality opportunities in education should support school-to-work transitions and better allocate the underutilised human capital reserves of migrants’ descendants. Conversely, long-lasting penalties in educational careers and integration processes may arise when children are physically separated from their parents because of delayed family reunification.
The skeletal anatomy of Manchurochelys manchoukuoensis (Pan- Cryptodira: Sinemydidae) from the Lower Cretaceous Yixian Formation

ABSTRACT Manchurochelys manchoukuoensis is a sinemydid stem-cryptodire turtle known by fossils from the Lower Cretaceous beds exposed in western Liaoning and Inner Mongolia of China. This fossil taxon is important for understanding the origin and evolution of Cryptodira (crown-group hidden-neck turtles). The holotype of M. manchoukuoensis was presumably lost during the Second World War and several aspects of the osteology of the species remains unknown. We here describe a near-complete fossil skeleton coming from the Lower Cretaceous Yixian Formation, western Liaoning, China, 50 km away from the type locality in the same formation. PKUP V1071 represents the most completely preserved specimen of the species and includes a well-preserved plastron, which was otherwise only known partially in the lost holotype. We provide a detailed osteological description of M. manchoukuoensis including data from micro-CT and X-ray computed laminography scanning of PKUP V1071. Of particular significance is the anchor-shaped entoplastron transversely extending to completely separate the small and triangular epiplastra from the hyoplastra; this peculiar morphology is otherwise only present in Sinemys spp. among turtles. Additional novel insights into plastron and cranial anatomy further support a close relationship between Sinemys and Manchurochelys.
Spatial Multiplexing Superimposed Pilots for Multicell Multiuser MIMO Uplink Systems

For a multiple-input multiple-output (MIMO) system, or a multiuser MIMO system, it is important to acquire the accurate channel state information. In this article, a superimposed-pilot-based channel estimation scheme is proposed for multicell multiuser MIMO uplink systems. In this scheme, the pilot sequences and data sequences are superimposed, but the space generated by the pilot sequences and the space spanned by data sequences are separated far enough in order to reduce interference. Based on this scheme, the minimum mean-square error channel estimation is deduced, and the optimal power allocation between the pilots and the data signals is derived to maximize throughput. These results show that our proposed scheme can overcome the pilot contamination and achieve better performance than the traditional time-multiplexing scheme with mutually orthogonal pilot sequences for different users when the coherent time slot is limited.
