Analysis of the Spatiotemporal Pattern and Mechanism of Land Use Mixture: Evidence from China’s County Data

The mixture of agricultural and non-agricultural land-use represents a new pattern of urbanization in the Global South. This mixture has hindered the improvement of land-use productivity and makes it difficult to achieve the centralized disposal of pollutants, which has resulted in the waste of land resources and serious environmental problems. Although many studies have investigated land-use mixture, most of them remain descriptive and lack quantitative examination and an in-depth mechanism analysis. Using raster land-use data, this paper examines the spatiotemporal pattern of the land-use mixture in China between 1990 and 2015 by calculating join counts values supplemented by landscape metrics, and attempts to explain the regional variations in land-use mixtures in recent years. The results show that, between 2000 and 2010, land-use was more mixed in fast-growing regions such as Zhejiang, Fujian, Chongqing, Guangdong, and some major metropolises and mining cities, and that, between 2010 and 2015, land-use was more mixed in Central China. Additionally, the results of econometric models reveal that mixed land-use can be alleviated in regions with strict land planning and management, such as urban agglomerations in the Yangtze River Delta and the Pearl River Delta, as well as in areas with high levels of urbanization. Furthermore, the results of a spatial heterogeneity analysis show that strict land management has played an important role in reducing the land-use mixture in Eastern China; however, it has not played a significant role in Central China. The findings of this study suggest that land-use should be appropriately planned and managed to ensure sustainable development.
Feasibility for Operationally Monitoring Ground-Based Multichannel Microwave Radiometer by Using Solar Observations

Ground-based multichannel microwave radiometers can observe the atmospheric microwave radiation brightness temperature and continuously provide temperature and humidity profiles of the troposphere. At present, microwave radiometers are operated in many countries for monitoring climate and meteorological phenomena, and there have been many microwave radiometers of this kind presently implemented in China, but they lack a unified monitor for their operational condition, which is necessary if they are taken as a network. For this reason, a real-time monitoring receiving system of radiometer is fundamental and important. In order to check the system stability and the antenna performances, this paper studied the feasibility of applying the solar signals to monitor the antenna alignment, antenna pattern and stability of a radiometer system in working for operational field applications. An experiment was performed and the results from the analysis of the annual variation features with long-term solar observation data at four frequencies, 22.235, 26.235, 30.000 and 51.250 GHz, show that an antenna pattern retrieved from solar observations agrees well with that retrieved from the traditional method. In addition, a daily analysis of the solar signals in online data of a radiometer can be used for monitoring the alignment of the antenna and the stability of the ground-based microwave radiometer system.
Impact of Bank Concentration and Financial Development on Growth Volatility: The Case of Selected OIC Countries

ABSTRACT This study investigates the impact of bank concentration and financial development on economic volatility for the Organization of Islamic Cooperation (OIC) member countries. Employing dynamic panel models, we find no evidence that bank concentration is significantly related to economic volatility when it is entered independently in the models. Meanwhile, financial development lowers economic volatility. Extending the models to include market structure–financial development interaction, we note that the impact of bank concentration on volatility depends on the level of financial development within OIC countries. More specifically, the volatility-increasing effect of bank concentration tends to be moderated by financial development. Accordingly, in the wake of banking sector consolidation in these countries, policymakers and regulators in OIC countries should focus on further developing their financial markets such that the negative consequences of resulting market concentration can be mitigated.
Combined grip strength and calf circumference as a useful prognostic system in patients with liver diseases: a large cohort study

Background Sarcopenia and body composition can be associated with mortality in chronic liver diseases (CLDs). We sought to identify predictors in CLD patients (n=631, 309 males) and create a prognostic model using easily available indexes. Methods Reference values for low-grip strength (GS) were 26 kg in men and 18 kg in women. Reference values for low-skeletal muscle index (SMI) were 7.0 kg/m2 in men and 5.7 kg/m2 in women using bioelectrical impedance analysis (BIA). Reference values for low-calf circumference (CC) were 34 cm in men and 33 cm in women. Reference values for high-waist circumference were 85 cm in men and 90 cm in women. Using significant factors in the multivariate analysis contributing to the overall survival (OS), we created a simple predictive model. Akaike information criterion (AIC) was compared. Results Men (P<0.0001), presence of liver cirrhosis (LC) (P<0.0001), presence of hepatocellular carcinoma (HCC) (P<0.0001), low-GS (P<0.0001), low-CC (P<0.0001), serum albumin (P=0.0355), estimated glomerular filtration rate (P=0.0461), hepatitis B virus (P=0.0044) and hepatitis C virus (P<0.0001) were significant factors contributing to the OS by the multivariate analysis. The study subjects were classified into the 4 groups (combined GS-SMI system): (I) low-GS and low-SMI (sarcopenia, n=73); (II) low-GS and high-SMI (n=65); (III) high-GS and low-SMI (n=110); and (IV) high-GS and high-SMI (n=383). The cumulative OS rates were well stratified among 4 groups (overall P<0.0001, AIC =360.895). The study subjects were also classified into the 4 groups (combined GS-CC system): (I) low-GS and low-CC (n=60); (II) low-GS and high-CC (n=78); (III) high-GS and low-CC (n=70); and (IV) high-GS and high-CC (n=423). The cumulative OS rates were also well stratified among 4 groups (overall P<0.0001, AIC =349.521). In receiver operating characteristic (ROC) curve analysis for CC based on the OS, the optimal cutoff point in men was 34.6 cm [area under the ROC (AUC) =0.70, sensitivity =0.558, specificity =0.842], and that in women was 32.8 cm (AUC =0.72, sensitivity =0.619, specificity =0.787). Conclusions CC can be an alternative marker for muscle mass in CLD patients. Our proposed combined GS-CC system can be helpful in the community settings without special equipment for muscle mass measurement.
Anaerobic 3-Methylhopanoid Production By An Acidophilic Phototrophic Purple Bacterium

Bacterial lipids are well preserved in ancient rocks and certain ones have been used as indicators of specific bacterial metabolisms or environmental conditions existing at the time of rock deposition. Here we show that an anaerobic bacterium produces 3-methylbacteriohopanepolyols (3-MeBHPs), pentacyclic lipids previously detected only in aerobic bacteria and widely used as biomarkers for methane-oxidizing bacteria. Both Rhodopila globiformis, a phototrophic purple nonsulfur bacterium isolated from an acidic warm spring in Yellowstone, and a newly isolated Rhodopila species from a geochemically similar spring in Lassen Volcanic National Park (USA), synthesized 3-MeBHPs and a suite of related BHPs and contained the genes encoding the necessary biosynthetic enzymes. Our results show that 3-MeBHPs can be produced under anoxic conditions and challenges the use of 3-MeBHPs as biomarkers of oxic conditions in ancient rocks and as prima facie evidence that methanotrophic bacteria were active when the rocks were deposited.
Investigating the influence of institutional perviousness on the adoption of body-worn cameras by United States police agencies

ABSTRACT Abstract There is evidence that body-worn cameras decrease rates of police use of force and improve citizens’ perceptions of police legitimacy. Yet, research examining the processes leading agencies to adopt body-worn cameras is sparse. Using the 2013 Law Enforcement Management and Administrative Statistics (LEMAS) data from U.S. police agencies of all sizes, this study examines the relevance of institutional perviousness for body-worn camera adoption. Perviousness governs the chances that an organization adopts a new policy or practice, as well as the extent to which an organization is internally aligned to implement the new innovation. Results demonstrate that perviousness increases the odds of agency body-worn camera adoption, alongside other organizational characteristics. The findings suggest that future research should consider the potential impact of perviousness when investigating other organizational outputs.
EFFECTS OF NACL STRESS ON LEAF GROWTH, PHOTOSYNTHESIS AND IONIC CONTENTS OF STRAWBERRY CVS 'ELSANTA' AND 'KORONA'

In a two-year study, strawberry (Fragaria x ananassa Duch.) cvs ‘Elsanta’ and ‘Korona’ showed differences in their sensitivities to salinity as applied by irrigating plants with nutrient solutions with 30 mM or 60 mM NaCl concentration. One month after start of treatments, necrotic symptoms appeared on leaf margins of ‘Elsanta’. ‘Korona’ leaves, however, showed any to few symptoms. During the first growing season, salinity impaired the growth of ‘Elsanta’ leaves as indicated by a reduction in leaf area, leaf expansion rate and dry weight. During the second season, the reduction in leaf growth was more severe. By comparison, growth of ‘Korona’ leaves was reduced only during the second season. Total leaf number was unaffected by salinity in both cultivars; however, the number of dead leaves increased significantly due to salinity in ‘Elsanta’, but remained fairly unchanged in ‘Korona’. Maximum assimilation rates and carboxylation efficiencies, calculated from the A/Ci curves of leaves, were reduced by 39% and 44% in ‘Elsanta’ and by 22% and 34% in ‘Korona’, respectively. The net photosynthetic rate of ‘Elsanta’ was slightly reduced in tendency by salt treatments, while in ‘Korona’ the reduction was significant at the highest salt treatment. Salinity had no effect on the Na+ content in leaves of both cultivars. However, the leaf Cl- content increased with increasing salt level, reaching maximum value in ‘Elsanta’ leaves treated with the highest salt level. This indicates that the effect of salt on leaves was due to Cl-, not to Na+. Root Na+ content increased with salinity in both cultivars. The increase in root Cl- content in ‘Elsanta’ was not significant, but it rose in tendency. Cl- content in ‘Korona’ roots increased significantly with increasing salt level. This suggest that ‘Korona’ strawberry is able to accumulate absorbed Cl- in root tissues, thus preventing the translocation of this toxic ion to the leaves.
Assessing the Willingness to Use Personal e-Transporters (PeTs): Results from a Cross-National Survey in Nine European Cities

In the last few years, there has been a strong increase in the interest in and usage of so-called “Personal e-Transporters” (PeTs), also referred to as micro-mobility devices. Empirical research on the usage of PeTs as a transport mode is virtually non-existent, especially within Europe. This paper aims to fill this gap by investigating people’s motivations and barriers to the use of PeTs. To this end, a behavioural survey was conducted in nine European cities. A representative sample of approximately 250 respondents per city was collected, resulting in a dataset, after data cleaning, of 2159 observations. Generally, respondents’ perceptions of PeTs are not (yet) very favourable. Respondents’ perceptions related to cost and safety received the lowest scores. The results from the transtheoretical model of behavioural change show that a variety of factors influence the stage of behavioural change in which the respondents can be situated. These factors include cycling norms, current walking behaviour, walking attitudes, pro-environmental orientation, gender, PeTs possession, cycling obstacles and subscription to a bicycle sharing service. An important strength of this study lies in the international nature and the size of the data collection, ensuring the reliability and transferability of the results to other cities. To the best of our knowledge, it is the first large-scale survey to investigate people’s travel behaviour related to the usage of PeTs and possibly the only large-scale investigation that took place before the deployment of shared e-scooters in many European cities. Furthermore, an explicit link is made with other modes of active transport (walking and cycling).
Individual and Socio-Cultural Factors as Driving Forces of the Purchase Intention for Organic Food by Middle Class Consumers in Indonesia

Abstract The growth of the organic food market attracts more and more attention from researchers and agribusiness entrepreneurs. This paper identifies the role of personal, social, cultural and psychological factors as driving forces for the intention to purchase organic food by middle income class consumers. Data was collected from 527 respondents. A Structural Equation Modeling (SEM) approach was used in the analysis. The results show that social, cultural, personal and psychological factors significantly influence consumer’s attitude toward organic food. Moreover, the intention of middle class consumers to purchase organic food is positively affected by attitudes. The results of this study provide an important contribution to marketing scholars and practitioners as well as policy makers, particularly to improve organic food consumption in the context of middle class consumer in emerging market.
Real Exchange Rates and Growth: Contractionary Depreciations or Appreciations?

This study investigates the impact of real exchange rates (RER) on growth of a large number of advanced (AE) and developing economies (DE) estimating conventional growth models augmented with global financial conditions variables. First of all, replicating Rodrik (2008) and following studies employing panel autoregressive distributed lag (PARDL) and PARDL mean group (PARDL-MG) models, we show that the expansionary depreciation findings for DE are often based on a misinterpretation of an error correction mechanism coefficient. Then, we investigate the relationship between RER and growth explicitly taking into account balance sheet or external debt vulnerabilities which often do not considered by conventional growth literature. Fully-Modified OLS estimation results show that, the external variables demonstrating global financial and monetary conditions are strongly significant in explaining growth in DE along with the conventional domestic variables including trade openness, human capital and savings. Furthermore, our results suggest that, RER depreciations are contractionary for DE with high external debt and expansionary for AE. However, higher trade openness decreases the contractionary impact of depreciations in both AE and DE. These results are robust for different RER and real income measures.
Modelling Software Architecture for Visual Simultaneous Localization and Mapping

Visual simultaneous localization and mapping (VSLAM) is an essential technique used in areas such as robotics and augmented reality for pose estimation and 3D mapping. Research on VSLAM using both monocular and stereo cameras has grown significantly over the last two decades. There is, therefore, a need for emphasis on a comprehensive review of the evolving architecture of such algorithms in the literature. Although VSLAM algorithm pipelines share similar mathematical backbones, their implementations are individualized and the ad hoc nature of the interfacing between different modules of VSLAM pipelines complicates code reuseability and maintenance. This paper presents a software model for core components of VSLAM implementations and interfaces that govern data flow between them while also attempting to preserve the elements that offer performance improvements over the evolution of VSLAM architectures. The framework presented in this paper employs principles from model-driven engineering (MDE), which are used extensively in the development of large and complicated software systems. The presented VSLAM framework will assist researchers in improving the performance of individual modules of VSLAM while not having to spend time on system integration of those modules into VSLAM pipelines.
The Role of Capital Expenditures, Human Development Index and Access to Electricity on Economic Growth in Java and Non-Java Islands

This study aims to determine whether there is a positive effect of capital expenditure, HDI and access to electricity on economic growth and is there a difference between economic growth in Java (in fact as a development area) and the Non-Java region. The data source used is secondary data in the form of the 2015 Ministry of Finance Report, as well as the publication of the Central Statistics Agency. The analysis used is the Ordinary Least Square (OLS) analysis where this test was carried out in 33 provinces in Indonesia (North Kalimantan was not used in the observation because it was a newly formed province). From the test results, it is found that: Capital Expenditure, HDI has a positive and significant effect on Economic Growth. Meanwhile, Electricity Accessibility has no influence on growth. This condition means that the economic growth in the Java Region is indeed higher than the economic growth outside Java.
Ferroelastic phase transition in [(C2H5)4N][(CH3)4N]MnBr4

ABSTRACT Crystal growth, DSC, X-ray structural studies, optical observation and dielectric studies for a new hybrid organic–inorganic [(C2H5)4N][(CH3)4N]MnBr4 crystal are presented. The studies revealed reversible first-order phase transition of a ferroelastic type at 484/482 K on a heating and cooling run, respectively. Unusual feature of this transition is reduction of symmetry on heating run. At room temperature phase the crystal is tetragonal with the space group and above the phase transition temperature it is orthorhombic with the space group . The symmetry change at the transition fulfills the reverse group–subgroup relation. Above the phase transition, the ferroelastic domain structure consistent with Aizu's species was revealed by polarized microscopy observation. The phase transition exhibiting such features has not been presented so far. Dielectric studies revealed a significant increase of losses connected with conductivity. The temperature dependence of conductivity and conductivity relaxation time fulfill the Arrhenius relation and activation energies are estimated.
Investigating the impacts of personality traits on collaborative consumption intention of luxury fashion products among middle-aged women

Collaborative consumption (CC) refers to the shared use of products or services in order to save costs and redistribute resources in a more sustainable way among the different agents participating in sharing economies. With the rapid popularity of CC in recent years, more and more academic research has been carried out on CC, but research exploring the impact of personality traits on consumer behavior is largely limited. To our best knowledge, existing research fails to explore CC applied to the luxury apparel context. Consequently, this study aims to investigate the impact of consumer personality traits on their attitudes and intention toward CC of luxury fashion products. This study draws a framework based on the theory of planned behavior (TPB) model introducing key personality traits, particularly, materialism, fashion leadership, and need for uniqueness as CC attitude and CC intention predictors. This research uses PLSSEM technique to analyze the data collected through a questionnaire administered to middle-aged Spanish women. The results indicate that fashion leadership had a positive influence on attitude toward CC and CC intention. Secondly, we found that consumer need for uniqueness significantly influenced attitude but had no significant impact on intention. Materialism on the other hand did not display a significant relationship with either CC attitude or intention.
Longitudinal patterns of food insecurity, the home food environment, and parent feeding practices during COVID‐19

The economic impacts of the coronavirus disease 2019 (COVID‐19) have drastically increased food insecurity in the United States. Initial data, collected a few months into the pandemic, showed that families, particularly those experiencing food insecurity, reported detrimental changes to their home food environment and parent feeding practices, compared to before COVID‐19.
Perceived stress and psychological well-being of working mothers during COVID-19: a mediated moderated roles of teleworking and resilience

PurposeThe present study examines the mediating role of teleworking and the moderating role of resilience in explaining the relationship between perceived stress and psychological well-being of working mothers in India. Conservation of resource theory (COR) is taken to support the present study.Design/methodology/approachThe data of 326 respondents has been collected from working mothers in various sectors of Delhi NCR region of India. Confirmatory factor analysis was used for construct validity, and SPSS Macro Process (Hayes) was used for testing the hypotheses.FindingsThe results of the study found an inverse association between perceived stress and psychological well-being. Teleworking acted as a partial mediator and resilience proved to be a significant moderator for teleworking-well-being relationship.Research limitations/implicationsThe study is based at Delhi NCR of India, and future studies may be based on a diverse population within the country to generalize the findings in different cultural and industrial contexts. The present work is based only on the psychological well-being of the working mothers, it can be extended to study the organizational stress for both the genders and other demographic variables.Practical implicationsThe study extends the research on perceived stress and teleworking by empirically testing the association between perceived stress and psychological well-being in the presence of teleworking as a mediating variable. The findings suggest some practical implications for HR managers and OD Practitioners. The organizations must develop a plan to support working mothers by providing flexible working hours and arranging online stress management programs for them.Originality/valueAlthough teleworking is studied previously, there is a scarcity of research examining the impact of teleworking on psychological well-being of working mothers in Asian context. It would help in understanding the process that how teleworking has been stressful for working mothers and also deliberate the role of resilience in the relationship between teleworking and psychological well-being due to perceived stress, as it seems a ray of hope in new normal work situations.
