An Empirical Study on Hazardous Chemicals Risk of Urban Residents in China: Analysis of Mediating Effect and Channel Preference of Response Action Decision Model

Because urban residents do not have a strong understanding of hazardous chemicals, they cannot effectively make response action decisions to ensure safety, protect lives, and reduce property damage. This paper constructs the Response Action Decision Model of hazardous chemicals, and analyzes the mediating effect of Information Processing and Threat Perception, as well as channel preferences of urban residents with different demographic characteristics. A total of 1700 questionnaires were collected in Chongqing, Tianjin, Fujian Zhangzhou, Shandong Zibo and Lanzhou, where there are significant hazardous chemicals factories. The results show that: Firstly, Information Processing and Threat Perception have significant mediating effects on the relationship between Mass Media, Social Media, Face-to-face communication and Response Action Decision in a single channel, which can effectively promote the spread effect of different channels, affecting the ways that urban residents make hazard response action decisions; secondly, Information Processing and Threat Perception do not have a mediating effect on the relationship between the channel combination of “Mass Media ↔ Social Media”, “Mass Media ↔ Face-to-face communication”, “Social Media ↔ Face-to-face communication” and Response Action Decision, and the channel combination can directly link to the Response Action Decision; thirdly, in terms of the extent that it affects urban residents to make response action decisions, Mass Media is greater than Social Media and greater than Face-to-face communication; fourthly, two demographic characteristics of gender and experience have a stronger moderating effect for the Mass Media channel, while other demographic characteristics have greater influences on the Response Action Decision Model; finally, the Response Action Decision Model can be better applied to those analyses and research which address threat perception of hazardous chemicals and response action decisions of urban residents in China.
Assessment of Ecosystem Service Supply, Demand, and Balance of Urban Green Spaces in a Typical Mountainous City: A Case Study on Chongqing, China

Objective measurement of the supply–demand of ecosystem services (ESs) has received increasing attention from recent studies. It reflects the relationship between green spaces and human society. However, these studies rarely assess the mountainous cities. To fill this gap, this study takes a typical mountainous city as a research case to reveal the supply–demand relationship of ecosystem services, then development and management strategies are proposed for different districts according to their spatial differentiation characteristics. Results shows that: (1) there are differences of ESs supply between each district, and supply from Banan District is significantly higher than others. (2) The demands for ES also vary widely, which are higher in the core urban areas. (3) There are different degrees of imbalance between supply and demand in each district. We classified green spaces into four types based on their supply–demand characteristics, and optimization strategies are proposed. We found that most of the districts are lack of ES supply while there is a relatively high demand for ES in Chongqing, and the balance of supply and demand between different districts varies greatly. Our study indicates that targeted urban green spaces strategies for different districts must be considered to adequately optimize ES in mountainous cities.
Occupation of young people in Mexico between 1992 and 2018: Studying, working, both or neither

We analyze the occupation of young people in Mexico between 1992 and 2018. A decrease in the disconnection rate is observed, with an exception during the 2008-2010 crisis. Probabilistic models for the year 2018 highlight inequalities between sex, household structure or territory. The main determinants of occupational pathways are the education level of the parents, having a child, and sex. Women are less represented in the labor market than men, and having children decreases the likelihood of them working, while, for men, this rate increases. Young people who grow up under more favorable circumstances are less likely to combine work and studies. For women, living in an urban area or a wealthier household is synonymous with labor insertion and lower disconnection. For men, these characteristics are associated at a young age with a higher level of disconnection rather than work. Our results reaffirm the importance of early intervention in improving opportunities and avoiding adverse outcomes during times of economic crisis.
Purified proteases of two Antarctic bacteria: from screening to characterization

Abstract Proteases are widely used in industrial processes, and the discovery of new, more kinetically efficient proteases can have a positive impact on industry. Enzymes from Antarctic microorganisms exhibit cold-adaptive properties, making them useful in biotechnology. The cold and harsh environment of Antarctica makes it a valuable source for new biotechnologically related enzymes. In this study, we characterized two cold-adapted proteases purified from Pseudoalteromonas issachenkonii P14M1-4 and Flavobacterium frigidimaris ANT34-7, isolated from King George Island, Antarctica, and compared these with proteases from the non-cold-adapted bacteria Bacillus licheniformis and Geobacillus stearothermophilus. The best temperature growing conditions were used for protease purification and characterization. The protease from P. issachenkonii P14M1-4 was identified as a 40–43 kDa metal-dependent subtilisin-like serine protease and the protease from F. frigidimaris ANT34-7 was identified as a 28 kDa metalloprotease. The enzymes showed an optimum temperature of between 35°C and 40°C and an optimum pH in the neutral to alkaline range. Their activation energies, catalytic constants and growth capacities at different temperatures categorize them as cold-adapted enzymes. We conclude that the characteristics exhibited by these proteases make them useful for biotechnological purposes requiring high activity at low temperatures. Moreover, to the best of our knowledge, this is the first characterization of a cold-adapted protease from F. frigidimaris.
The Incidence of Isolated Ventricular Septal Defect in Libyan Newborns

This study aimed to evaluate the incidence and spontaneous closure of ventricular septal defects in a randomly selected newborn population, using color Doppler echocardiographic screening. Color flow Doppler echocardiographic screening was performed in 635 neonates within the first week of life. Patients with a ventricular septal defect were also followed up for 6 months to detect spontaneous closure rate and its timing. The incidences of a ventricular septal defect in all neonates, preterm neonates, and term neonates were found as 48.8/1,000, 64/1,000, and 48.1/1,000 live births, respectively. Only three patients were symptomatic. 21 cases had a muscular ventricular septal defect and 10 cases had a perimembranous ventricular septal defect. Most of them had a small ventricular septal defect (≤3 mm). Spontaneous closure was observed in 64.5% of ventricular septal defects within 6 months Closure rate was found as 80% for preterm infants and 66.8% for term infants (p>0.05). The incidence of a ventricular septal defect was considerably high in neonates when routine color flow Doppler echocardiographic examination was performed. Despite the increased incidence of ventricular septal defect, spontaneous closure rate was remarkably high within the first 6 months of life. These defects may result from delayed physiologic development and have a good prognosis.
The Work of Special Education Teachers in the Tiered Support System: The Finnish Case

ABSTRACT This study investigated primary school special education teachers’ (SETs’) (N = 283) conceptions on their work descriptions and uses of pedagogical documents after a reform in the national support framework. The respondents of this survey reported working mostly in Tiers 1 and 2 when all their tasks (instruction, consultation, and managerial tasks) were considered. The responsibilities of the SETs were, however, more clearly defined in Tier 3. The SETs allocate their work autonomously, but their work description is related to their workload. Clarifications in work descriptions and further elaboration of school’s tiered support functions, emphasizing collaborative practices, are suggested.
Making a Global Image of the World: Science, Cosmography and Navigation in Times of the First Circumnavigation of Earth, 1492-1522

The voyages of exploration and discovery during the period of European maritime expansion and the immense amount of information and artefacts they produced about our knowledge of the world have maintained a difficult, if not non-existent, relationship with the main historiographical lines of the history of early modern science. This article attempts to problematize this relationship based on a historical account that seeks to highlight the scientific and institutional mechanisms that made the Magellan-Elcano voyage, the first modern voyage, possible. The text argues that this voyage was the first modern voyage because it allowed the construction of a new scientific and cartographic image of the globe and contributed to our understanding of the world as a global world, altering the foundations on which modern European economic and geographic thought was based. In that sense, the voyage was something extraordinary, but not completely unexpected. It responded to a complex process of expansionary policy and technical development that dated back to the 15th century, which in 1519 was sufficiently articulated to carry out a great feat.
Feedback inhibition by GABAergic interneurons that are driven by dorsal raphe-projecting pyramidal neurons of the medial prefrontal cortex suppress feeding of adolescent female mice undergoing activity-based anorexia

Anorexia Nervosa (AN) is characterized by voluntary food restriction, excessive exercise and mortality rate surpassing that of major depression. Activity-based anorexia (ABA) is an animal model that captures these characteristics of AN, thus having the potential to reveal the neurobiology underlying individual differences in AN vulnerability. Dorsal raphe (DR) is known to regulate feeding but its role in ABA remains unexplored. Through chemogenetic activation, we investigated the role of mPFC pyramidal neurons projecting to DR (mPFC→DR) in an animal’s decision to eat or exercise following ABA induction. Although the DREADD ligand C21 could activate 44% of the mPFC→DR neurons, this did not generate significant group mean difference in the amount of food intake, compared to control ABA mice without chemogenetic activation. However, further analysis of individual animals’ responses to C21 revealed a significant, positive correlation between food intake and mPFC→ DR neurons that co-express cFos, a marker for neuronal activity. cFos expression by GABAergic interneurons (GABA-IN) in mPFC was significantly greater than that for the control ABA mice, indicating recruitment of GABA-IN by mPFC→DR neurons. Electron microscopic immunohistochemistry (EM-ICC) revealed that GABAergic innervation is 60% greater for the PFC→DR neurons than the Layer 5 pyramidal neurons without projections to DR. Moreover, individual differences in this innervation correlated negatively with food intake specifically on the day of C21 administration. We propose that C21 activates two antagonistic pathways: 1) PFC→DR pyramidal neurons that promote food intake; and 2) GABA-IN in the mPFC that dampen food intake through feedback inhibition of mPFC→DR neurons.
Li

Severe lithium (Li) dendrite growth caused by the uneven overpotential deposition is a formidable challenge for high energy density Li metal batteries (LMBs). Herein, we investigate a synergetic interfacial kinetic to regulate Li deposition behavior and stabilize Li metal anode. Through constructing Li alloying matrix with a bi-functional silver (Ag)-Li 3 N blended interface, fast Li + conductivity and high Li af ﬁ nity can be achieved simultaneously, resulting in both decreased Li nucleation and mass transfer-controlled overpotentials. Beyond these properties, a more important feature is demonstrated herein; that is, the inward diffusion depth of the Li adatoms inside of the Ag site can be restricted by the Li + solvation structure in a highly coordinating environment. The latter feature can ensure the durability of the operational Ag sites, thereby elongating the Li protection ability of the Ag-Li 3 N interface greatly. This work provides a deep insight into the synergetic effect of functional alloying structure and Li + solvation mediated interfacial kinetic on Li metal protection.
SLCO4A1-AS1 Facilitates the Malignant Phenotype via miR-149-5p/STAT3 Axis in Gastric Cancer Cells

Solute carrier organic anion transporter family member 4A1 (SLCO4A1-AS1), a newly discovered lncRNA, may exert effects in tumors. Since its role in gastric cancer remains obscure, we sought to explore the mechanism of SLCO4A1-AS1 in gastric cancer. The relationship among SLCO4A1-AS1, miR-149-5p, and STAT3 was detected by bioinformatics, dual luciferase analysis, and Pearson's test, and the expressions of these genes were determined by quantitative real-time PCR and Western blot. Moreover, CCK-8, flow cytometry, wound healing assay, and Transwell analysis were performed to verify the function of SLCO4A1-AS1 in gastric cancer. Rescue experiments were used to detect the role of miR-149-5p. The expressions of SLCO4A1-AS1 and STAT3 were increased, while the expression of miR-149-5p was suppressed in gastric cancer tissues and cell lines. In addition, STAT3 expression was negatively correlated with miR-149-5p expression but was positively correlated with SLCO4A1-AS1 expression. Overexpression of SLCO4A1-AS1 promoted cell viability, migration, invasion, and STAT3 expression but suppressed apoptosis, while knockdown of SLCO4A1-AS1 had the opposite effect. SLCO4A1-AS1 bound to miR-149-5p and targeted STAT3. Moreover, miR-149-5p mimic inhibited the malignant development of gastric cancer cells and obviously reversed the function of SLCO4A1-AS1 overexpression. Our research reveals that abnormally increased SLCO4A1-AS1 expression may be an important molecular mechanism in the development of gastric cancer.
Loss Aversion in Farmland Price Expectations

Farmland price expectations play a critical role in farm investment decisions, yet previous studies suggest that market experts’ expectations are not rational. That is, market experts do not make efficient use of all available information. This article tests the degree to which expectations are consistent with rational expectations, under symmetric and asymmetric loss, based on aggregate expectations from Purdue Farmland Values and Cash Rent Survey between 1979 and 2019. We find robust evidence that farmland market experts are averse to overpredicting farmland price increases. When this asymmetry is considered, farmland market experts are shown to be rational loss minimizers.
Self‐Protective Room‐Temperature Phosphorescence of Fluorine and Nitrogen Codoped Carbon Dots

The unstable triplet excited state is a core problem when developing self‐protective room temperature phosphorescence (RTP) in carbon dots (CDs). Here, fluorine and nitrogen codoped carbon dots (FNCDs) with long‐lived triplet excited states, emitting pH‐stabilized blue fluorescence and pH‐responsive green self‐protective RTP, are reported for the first time. The self‐protective RTP of FNCDs arises from n–π * electron transitions for CN/CN bonds with a small energy gap between singlet and triplet states at room temperature. Moreover, the interdot/intradot hydrogen bonds and steric protection of CF bonds reduce quenching of RTP by oxygen at room temperature. The RTP emission of FNCDs shows outstanding reversibility, while the blue fluorescence emission has good pH stability. Based on these FNCDs, a data encoding/reading strategy for advanced anticounterfeiting is proposed via time‐resolved luminescence imaging techniques, as well as steganography of complex patterns.
Self-rating of depression in elderly prisoners in North Rhine-Westphalia, Germany

Aim: Against the background of the rising number of elderly people being incarcerated and the rare data on this special subgroup, the aim of our study was to collect first empirical data on the affective state of elderly prisoners in North Rhine Westphalia, Germany. Methods: Data were collected in nine German prisons. We included elderly prisoners from pretrial prevention, penal sentences, open enforcement, preventive detention and from special detention units for elderly inmates. For the evaluation of the affective state, we used the Patient Health Questionnaire (PHQ-9). Sociodemographic and crime-related characteristics were documented. Findings: In total, n=116 prisoners (91.4% male) were included. The age ranged from 53 to 91 years (65.6±6.3 years). In our sample, 48% reported at least mild depressive symptoms, which is a significantly higher prevalence of depressive symptomatology than in the general population aged 60 years and older. Differences were found with regard to the type of detention, as prisoners in open enforcement showed significantly less symptoms compared to those in pretrial prevention and preventive detention. The participants reported in general more somatic symptoms as sleep disturbances and fatigue compared to mood items as feelings of sadness. Originality: It is the first study assessing the affective state of older prisoners in Germany. The high rate of depressive symptoms in our sample is in line with findings from international studies underlining the need for adequate diagnostics and therapy. In addition, in a previous study depression was indirectly linked with a greater risk of re-incarceration, fortifying the need for successful treatment of depression in prison both for the individuum and for society.
The Event Horizon Telescope Image of the Quasar NRAO 530

We report on the observations of the quasar NRAO 530 with the Event Horizon Telescope (EHT) on 2017 April 5−7, when NRAO 530 was used as a calibrator for the EHT observations of Sagittarius A*. At z = 0.902, this is the most distant object imaged by the EHT so far. We reconstruct the first images of the source at 230 GHz, at an unprecedented angular resolution of ∼20 μas, both in total intensity and in linear polarization (LP). We do not detect source variability, allowing us to represent the whole data set with static images. The images reveal a bright feature located on the southern end of the jet, which we associate with the core. The feature is linearly polarized, with a fractional polarization of ∼5%–8%, and it has a substructure consisting of two components. Their observed brightness temperature suggests that the energy density of the jet is dominated by the magnetic field. The jet extends over 60 μas along a position angle ∼ −28°. It includes two features with orthogonal directions of polarization (electric vector position angle), parallel and perpendicular to the jet axis, consistent with a helical structure of the magnetic field in the jet. The outermost feature has a particularly high degree of LP, suggestive of a nearly uniform magnetic field. Future EHT observations will probe the variability of the jet structure on microarcsecond scales, while simultaneous multiwavelength monitoring will provide insight into the high-energy emission origin.
Relationship between Internet addictions and academic performance among Afghan universities students

This study evaluates the relationship between Internet addiction and academic performance among students of eight Afghan universities. The differences between internet addiction in terms of gender was also identified. The survey/research method adopted the Internet Addiction Test (IAT) based on Young’s survey applied with some modifications. From 1000 distributed questionnaires only 976 participants (358 females, and 618 males) were responded completely. The descriptive analysis was used to identify the demographic characteristics of student’s Internet usage profile. The independents sample t-test was performed to determine the differences in the level of Internet addiction in terms of gender. Statistical significance was set at a value of p <0.01. Likewise, the correlation test was implemented to identify the relationship between Internet addiction and academic performance, with referencing of sample. The results indicated that statistically there is a significant correlation among Internet addiction and academic performance. Results also indicated that statistically there were significant differences between Internet addictions in terms of demographic characteristics. This study suggests that future researchers need to work on large sample while conducting the related research. It emphasizes that students should concentrate more on their academic activities than spending time on unnecessary Internet surfing. Findings also revealed that, in Afghanistan the problem of Internet addiction is not a serious challenge, but this information should be disseminated among undergraduate university students to stop the indulgent in using the Internet.
Types of Inter-Firm Relations and Their Comparative Economic Performance: Evidence from Russian Retail Market

Based on economic-sociological, marketing, and strategic management literature, we combine two classifications of inter-firm relations (horizontal and vertical) and propose the original ty-pology of four ideal types of inter-firm exchange. The quantitative prevalence and the comparative economic efficiency of each ideal type are estimated using indicators of sales dynamics, changes in commodity range and competitive positions. The empirical analysis is based on data from a standardized survey of 684 corporate managers (of retailer and supplier firms) operating in Russia in the food and non-food markets conducted by the HSE in 2016. The analysis revealed high prevalence of building intensive inter-firm relations in the supply chain and low prevalence of network connections with competitors. Additionally, the combination of horizontal relationships with competitors and building vertical relationships in accordance with the concept of relationship marketing is associated with the highest rates of economic efficiency.
