Morphophysiological aspects of Erythroxylum pauferrense Plowman seedlings submitted to shading

Sunlight directly influences on the development of forest species by affecting the attributes of plant growth and physiology. Among these species, Erythroxylum pauferrense Plowman is considered a rare species, as its distribution is restricted only to the state of Paraíba. Therefore, studies are needed that seek to evaluate the adaptation, development and propagation of the species under different environmental conditions. This study aimed to evaluate morphophysiological aspects of Erythroxylum pauferrense seedlings submitted to different levels of shading. The experiment was carried out under greenhouse condition in a completely randomized design with five treatments (0, 30, 50, 70, and 90% shading) and eight replicates. Growth characteristics, morphofunctional attributes, gas exchange, chlorophyll (Chl) a fluorescence, and Chl content were evaluated. Data were submitted to analysis of variance followed by polynomial regression analysis. Results showed that plants grown under 30 to 50% shading showed higher plant height, stem diameter, absolute growth rate for plant height, leaf dry mass, stem dry mass, total dry mass, Dickson’s quality index, leaf area, and leaf area index, as well as net assimilation rate of CO2, stomatal conductance, transpiration, instantaneous water use efficiency, and Chl a, b, and a+b contents. Therefore, levels from 30 to 50% shading are the most recommended for the production of Erythroxylum pauferrense seedlings. We recommend using Erythroxylum pauferrense to reforest the understory in disturbed areas in Brejos de Altitude and large-scale production of seedlings under intermediate levels of shading.
A Study on Differences between Professional Endoscopists and Gastroenterologists in Endoscopic Detection and Standard Pathological Biopsy of Inflammatory Bowel Diseases

Objective To assess whether professional endoscopists need additional training on inflammatory bowel disease (IBD) diagnosis. Methods This retrospective study was conducted in patients with IBD, including Crohn's disease (CD) and ulcerative colitis (UC), which were diagnosed and treated for the first time in our hospital between January 2005 and December 2020. Doctors including gastroenterologists (group G) and professional endoscopists (group E) participated in the study. The data divided into CD or UC and group G or group E were compared. Results Patients with CD exhibited higher rates of terminal ileal lesions, reexamined colonoscopy within 6 months, and intestinal stenosis than patients with UC (P < 0.001). The positive endoscopic IBD diagnosis rate was significantly higher in group G than in group E (89.6% vs. 74.0%, P < 0.001). In the subgroup analysis for patients with CD, the positive endoscopic IBD diagnosis rate was significantly higher for group G than for group E (81.5% vs. 41.8%, P < 0.001). However, the two groups exhibited no significant difference in the subgroup analysis for patients with UC (94.1% vs. 86.5%, P = 0.060). Group G exhibited a higher rate of terminal ileal intubation (83.1% vs. 65.3%, P < 0.001) and standard pathological biopsy (72.7% vs. 26.0%, P < 0.001) than Group E. Conclusion Professional endoscopists showed lower rates of terminal ileal intubation, positive endoscopic diagnosis, and standard pathological biopsy than gastroenterologists. Hence, additional training on IBD, particularly on CD, must be provided to professional endoscopists to increase their efficiency for terminal ileal intubation and positive endoscopic diagnosis and to enhance their awareness regarding standard biopsy.
China's Economic Forecast Based on Machine Learning and Quantitative Easing

In this paper, six variables, including export value, real exchange rate, Chinese GDP, and US IPI, and their seasonal variables, are used as determinants to model and forecast China's export value to the US using three methods: BP neural network, ARIMA, and AR-GARCH. Error indicators were chosen to compare the simulated and predicted results of the three models with the real values. It is found that the results of all three models are satisfactory, although there are some differences in their simulation and forecasting capabilities, but the ARIMA model has a clear advantage. This paper analyses the reasons for these results and proposes suggestions for improving China's exports in the context of the models.
Health and well-being of first responders: The role of psychological capital, self-compassion, social support, relationship satisfaction, and physical activity

Abstract First responders are frequently exposed to dangerous, high-stress, and traumatic situations, leaving them susceptible to both physical and mental health consequences. The current study explored factors that relate to both health and well-being in 391 first responders (255 males and 136 females), aged 18–64 years. The study’s aim was to explore the role of psychological capital (PsyCap), self-compassion, social support, relationship satisfaction, and physical activity in the health and well-being of first responders. Data was collected using an online survey which was distributed to first responders, including firefighters, police officers, and emergency medical personnel, in the state of Massachusetts, USA. Descriptive and correlational statistics were performed, followed by hierarchical multiple regression analysis and path analysis, revealing that PsyCap, self-compassion, social support, relationship satisfaction, as well as physical activity are key mediating factors impacting the health and well-being of first responders. Findings pose as a foundation and stepping-stone to improve first responders’ health and well-being. In particular, a multifaceted approach to intervention drawing on the combined variables identified in the path model is indicated.
Horizontal heat impacts and shading effects of buildings on surface soil layer in Beijing, China

Thermal condition of the surface soil layer was neglected due to much concern of the urban heat island effect, which has an important impact on cities. In this study, on-site measurements of surface soil layer temperatures were conducted between two east-west oriented buildings in the winter, spring and summer. Building shade was shown to reduce average surface soil layer temperatures to 0.33, 0.33 and 0.37°C in three seasons, respectively. The horizontal heat flux between the building and the soil was calculated and showed different intensities at various monitoring sites. Additionally, the building shade could reduce and stabilize the surface soil layer temperature. According to the analytic hierarchy process, among six energy factors only horizontal heat flux between the building and the soil was correlated significantly (p <0.05) to the different surface soil layer temperatures. This has a key or dominant role in affecting the difference in surface soil layer temperatures, which was influenced by the building shade. Moreover, the soil warming rate was reduced by the building shade (50% at most). The surface soil layer temperatures at various observation points were compared with the air temperature. The surface soil layer was found to have different roles between two sites in three seasons.
Chalcone Derivatives as Potential Inhibitors of P-Glycoprotein and NorA: An In Silico and In Vitro Study

The human P-glycoprotein (P-gp) and the NorA transporter are the major culprits of multidrug resistance observed in various bacterial strains and cancer cell lines, by extruding drug molecules out of the targeted cells, leading to treatment failures in clinical settings. Inhibiting the activity of these efflux pumps has been a well-known strategy of drug design studies in this regard. In this manuscript, our earlier published machine learning models and homology structures of P-gp and NorA were utilized to screen a chemolibrary of 95 in-house chalcone derivatives, identifying two hit compounds, namely, F88 and F90, as potential modulators of both transporters, whose activity on Staphylococcus aureus strains overexpressing NorA and resistant to ciprofloxacin was subsequently confirmed. The findings of this study are expected to guide future research towards developing novel potent chalconic inhibitors of P-gp and/or NorA.
Study of smart antennas and MU-MIMO techniques for indoor radio engineering and planning tools

The deployment facility and flexibility of wireless technologies have allowed considerable evolution of IEEE 802 . 11 standards. The arrival of the optical fiber to the home has further motivated the research studies to increase data rates and capacity. ln this context, the latest IEEE 802.l lac standard ratified in 2014 proposes new technologies to achieve maximum data rates above 1 Gbit/s. ln particular, 802.l lac includes the Multi-User Multiple Input Multiple Output (MU-MIMO) and Transmit Beamforming (TxBF). These smart antenna technologies assume a variable transmit antenna pattern in function of the users' position and the corresponding multipath propagation channel characteristics. However, the actual radio planning tools give a fixed coverage map in dependent of any adaptive or smart antenna processing. This thesis studies the impact of the MU-MIMO and TxBF techniques on radio engineering, system optimization as well as radio planning tools. Indeed, the first part of this thesis deals with refining the sum rate capacity gains by identifying interesting system configurations and optimal system parameters. The second part addresses the beamforming gains in terms of the Signal-to-Noise Ratio (SNR) gain and interference level to have realistic radio coverage modeling.
The Interplay Between Status and Affection Needs: Testing the Imbalanced Needs Theory of Aggression in Adulthood

Status and affection are both goals related to social needs. The imbalanced needs theory of aggression proposes that although aggression can be used to realize status, this strategy is detrimental for realizing affection in the same social context. Thus, to the degree that the social circles overlap in which status and affection needs are realized, it becomes more costly (in terms of affection) to achieve status via aggression. This theory was tested for different forms of aggression, in different contexts, in a sample of adults from the general population (N = 253, M age = 29.95, SD = 2.60, 78% female). Participants reported on social needs with the Interpersonal Goals Inventory and reported on general measures of physical and social aggression, as well as rule breaking, and aggression at the workplace and in intimate partner relationships. As hypothesized, status needs were associated with physical aggression when affection needs were weak. This interaction, though to a lesser degree, also extended to social forms of aggression and rule breaking. At the workplace, aggression was only related to weak affection needs, whereas aggression in intimate partner relationships was, as expected, unrelated to both social needs. Together, these findings support the results of an earlier test of the imbalanced needs theory of aggression in adolescence, and encourage more research into the link between aggression and the satisfaction of social needs.
Soluble Epoxide Hydrolase Inhibition Protected against Diabetic Cardiomyopathy through Inducing Autophagy and Reducing Apoptosis Relying on Nrf2 Upregulation and Transcription Activation

Background Many patients with diabetes die from diabetic cardiomyopathy (DCM); however, effective strategies for the prevention or treatment of DCM have not yet been clarified. Methods Leptin receptor-deficient (db/db) mice were treated with either the soluble epoxide hydrolase (sEH) inhibitor AUDA or vehicle alone. A virus carrying Nrf2 shRNA was used to manipulate Nrf2 expression in db/db mice. Cardiac structures and functions were analyzed using echocardiography and hemodynamic examinations. Primary cardiomyocytes cultured under high glucose and high fat (HGHF) conditions were used to conduct in vitro loss-of-function assays after culture in the presence or absence of AUDA (1 μM). Fluorescence microscopy-based detection of mCherry-GFP-LC3 was performed to assess autophagic flux. Results The sEH inhibitor AUDA significantly attenuated ventricular remodeling and ameliorated cardiac dysfunction in db/db mice. Interestingly, AUDA upregulated Nrf2 expression and promoted its nuclear translocation in db/db mice and the HGHF-treated cardiomyocytes. Additionally, AUDA increased autophagy and decreased apoptosis in db/db mice heart. Furthermore, the administration of AUDA promoted autophagic flux and elevated LC3-II protein level in the presence of bafilomycin A1. However, AUDA-induced autophagy was abolished, and the antiapoptotic effect was partially inhibited upon Nrf2 knockdown. Conclusion Our findings suggest that the sEH inhibitor AUDA attenuates cardiac remodeling and dysfunction in DCM via increasing autophagy and reducing apoptosis, which is relevant to activate Nrf2 signaling pathway.
Survivors’ Concerns During the COVID-19 Pandemic: Qualitative Insights From the National Sexual Assault Online Hotline

With the onset of the COVID-19 pandemic and the implementation of stay-at-home orders in March 2020, experts warned of the possible threat of increased interpersonal violence among individuals isolated with abusers. Researchers have sought to understand how the pandemic impacted victims primarily through the analysis of administrative data sources, such as hospital and police records. However, the preponderance of this data shows a decrease in formal help-seeking among victims during the pandemic, speaking to an impaired access to services but limiting our understanding of other ways in which the pandemic has affected survivors. To overcome these limitations, we examined data collected about users of the National Sexual Assault Online Hotline (NSAOH). Information was collected through staff based on retrospective recall following one-on-one chat sessions with 470 victims of sexual violence who contacted the NSAOH in the first six months of the pandemic and discussed COVID-19-related concerns. We qualitatively examined open-ended descriptions of COVID-19-related concerns and identified the four most common: (1) mental health concerns, (2) creation or exacerbation of an unsafe living situation, (3) not being able to access services, and (4) not having access to a mandatory reporter or trusted adult. These findings demonstrate the myriad ways in which the pandemic affected the lives of victims of sexual violence and can inform practices for services and practitioners to best meet the needs of survivors moving forward. Specifically, these findings highlight the need for more accessible mental health services and funding for sexual assault service providers, as well as the importance of safety planning, particularly in times of crisis.
Experiments investigating fuel spread behaviors for continuous spill fires on fireproof glass

A series of large-scale spill fire experiments with continuous discharge on a rectangular fireproof glass sheet were conducted, to better understand spill fire spread behaviors on land. JP-5 and heptane were selected as the fuels, with discharge rates varying from 0.93 to 6.82 L/min. Results show that the spread process can be divided into five phases: spread burning, shrink burning, quasi-steady burning, boiling burning, and extinguished. Not all of the burning phases appear during the process, which is related to the burning scale and the type of fuel. The burning rate of the quasi-steady burning phase is smaller than that of pool fires under the same burning scale. The ratio of the spill fire burning rate to the pool fire burning rate is close to 0.54 for JP-5 and 0.78 for heptane. In addition, we observed that the burning areas expand quickly at the beginning of a boiling burning phase and that the disturbance or entrainment of the flames becomes violent at the beginning of this phase. In the spread process, the empirical correlation between the maximum burning areas ( A max ) and the discharge rate ( Q · in ) is A max = 0 . 057 ( Q · in / W ) 0 . 875 (W is the width of glass) for JP-5, and A max = 0 . 13 ( Q · in / W ) 0 . 61 for Heptane. The ratio of maximum area to quasi-steady area is approximately 1.46 in the experiments.
Limiting calcium overload after cardiac arrest: The role of human albumin in controlled automated reperfusion of the whole body

Background Regarding the overall inadequate results after cardiopulmonary resuscitation, the development of new treatment concepts is urgently needed. Controlled Automated Reperfusion of the whoLe body (CARL) represents a therapy bundle to control the conditions of reperfusion and the composition of the reperfusate after cardiac arrest (CA). The aim of this study was to investigate the plasma expander’s role in the CARL priming solution and examine its mechanism of action. Methods Viscosity, osmolality, colloid osmotic pressure (COP), pH and calcium binding of different priming solutions were measured in vitro and compared to in vivo data. N = 16 pigs were allocated to receive CARL following 20 min of untreated CA with either human albumin 20% (HA, N = 8) or gelatin polysuccinate 4% (GP, N = 8). Blood gas analyses were performed during the first hour of reperfusion and catecholamine and fluid requirements were recorded. Neurological outcome was assessed by neurological deficit scoring (NDS) on the seventh day. Results In vitro, addition of HA to the CARL priming solution resulted in higher COP and higher calcium-binding than GP. In vivo, treatment with HA led to greater reduction of ionized calcium and higher extracorporeal flows within the first 30 min of reperfusion with no difference in catecholamine support and fluid requirement. Seven-day survival of 75% with no difference in NDS was observed in both groups. Conclusions Our data show that the plasma expander in the CARL priming solution has a significant effect on the initial reperfusate and can potentially influence the course of resuscitation. However, seven-day survival and NDS did not differ between groups.

An Investigation into the Use of Competency Frameworks for Recruitment and Selection in a Financial Services Organisation in Dublin

"The secret of my success is that we have gone to exceptional lengths to hire the best people in the world. " – Steve Jobs, Co-founder of Apple Inc. The overall purpose of this dissertation is to establish why a prominent financial services Organisation in Dublin uses a competency framework to support their recruitment and selection agenda. The Organisation has significant recruitment and operational targets for the next number of years. It is of fundamental importance that the framework continues to facilitate the hiring of the most efficient and effective employees to enable the Organisation to reach its goals and objectives. This has prompted the researcher to re-visit the competency debate, a debate that has somewhat been neglected in recent years, to assess recent published works in academia and practice around competencies and competency models. The Literature Review provides a comprehensive examination of literature on competencies and competency frameworks with focus on most recent works. The research uses a qualitative approach for data collection and examines interview responses from the HR function, as key managers of the model and the Finance area, as a sample of business respondents, within the Organisation. The findings herein establish that, despite a lack of recent academic research in this area, competencies and competency based frameworks are still very much utilised for recruitment and selection in Organisations. Such frameworks continue to provide a consistent means to assess talent.
Positive Definite Functions on Products via Fourier Transforms: Old and New

Abstract A number of consistent models describing stationary positive definite functions on stem from Bochner’s celebrated theorem characterizing continuous and stationary positive definite functions on If denotes the unit sphere in the same is true of positive definite functions on which are radial with respect to the component and stationary with respect to the component. In this paper, we summarize results on these topics, mainly those that somehow characterize the positive definiteness of the function through Fourier transforms of the sections of the function itself. We present a new perspective on the existent results in the literature along with new characterizations and applications.
Towards a constructed order of co-governance: Understanding the state–society dynamics of neighbourhood collaborative responses to COVID-19 in urban China

The state–society relationship in neighbourhood governance has been a focal topic in the urban governance literature, though the existing scholarship was primarily drawn from non-crisis situations. Adopting a mixed-methods approach, this study investigates the intricate state–society dynamics manifested at the neighbourhood scale as state and societal actors collaborated during China’s COVID-19 responses. Our study reveals a pattern of collaborative rather than confrontational dynamics between resident committees and other stakeholders during pandemic responses, which reflects the emergence of a constructed order of neighbourhood co-governance in urban China. Previous community-building reforms consolidated the political legitimacy, power and capacity of resident committees, which were empowered to play a critical coordinating role in bridging hierarchical state mobilisation and horizontal stakeholders in the collaborative pandemic responses. These findings contribute to a more nuanced understanding of neighbourhood co-governance in the international literature and provide lessons for resilience governance from a comparative lens.
