Impact of exogenous hydrogen peroxide on osteogenic differentiation of broiler chicken compact bones derived mesenchymal stem cells
Authors: Tompkins Y. H. , Liu G. , Kim W. K.
Published: January 2023

The effects of hydrogen peroxide (H2O2) on the osteogenic differentiation of primary chicken mesenchymal stem cells (MSCs) were investigated. MSCs were subjected to an osteogenic program and exposed to various concentrations of H2O2 for 14 days. Results showed that high concentrations of H2O2 (200 and 400 nM) significantly increased pro-apoptotic marker CASP8 expression and impaired osteogenic differentiation, as indicated by decreased mRNA expression levels of osteogenesis-related genes and reduced in vitro mineralization. In contrast, long-term H2O2 exposure promoted basal expression of adipogenic markers at the expense of osteogenesis in MSCs during osteogenic differentiation, and increased intracellular reactive oxygen species (ROS) production, as well as altered antioxidant enzyme gene expression. These findings suggest that long-term H2O2-induced ROS production impairs osteogenic differentiation in chicken MSCs under an osteogenic program.

Introduction

The soil houses a tremendous amount of micro-organisms, many of which are plant parasites and pathogens by feeding off plant roots for sustenance. Such root pathogens and parasites often rely on plant-secreted signaling molecules in the rhizosphere as host guidance cues. Here we describe the isolation and characterization of a chemoattractant of plant-parasitic root-knot nematodes (Meloidogyne incognita, RKN).

Methods

The Super-growing Root (SR) culture, consisting of excised roots from the legume species Lotus corniculatus L., was found to strongly attract infective RKN juveniles and actively secrete chemoattractants into the liquid culture media. The chemo-attractant in the culture media supernatant was purified using hydrophobicity and anion exchange chromatography, and found to be enriched in carbohydrates.

Results

Monosaccharide analyses suggest the chemo-attractant contains a wide array of sugars, but is enriched in arabinose, galactose and galacturonic acid. This purified chemoattractant was shown to contain pectin, specifically anti-rhamnogalacturonan-I and anti-arabinogalactan protein epitopes but not anti-homogalacturonan epitopes. More importantly, the arabinose and galactose sidechain groups were found to be essential for RKN-attracting activities. This chemo-attractant appears to be specific to M. incognita, as it wasn’t effective in attracting other Meloidogyne species nor Caenorhabditis elegans.

Discussion

This is the first report to identify the nematode attractant purified from root exudate of L corniculatus L. Our findings re-enforce pectic carbohydrates as important chemicals mediating micro-organism chemotaxis in the soil, and also highlight the unexpected utilities of the SR culture system in root pathogen research.
Controlled-release urea application and optimized nitrogen applied strategy reduced nitrogen leaching and maintained grain yield of paddy fields in Northwest China

Published: January 2023

Nitrogen loss from paddy fields contributes to most of the nitrogen pollution load in the Ningxia Yellow River irrigation area, threatening the water quality of the Yellow River. Consequently, optimizing the nitrogen management practices in this area is essential, which can maintain paddy grain productivity and reduce nitrogen loss simultaneously. Five treatments with different nitrogen application rates and nitrogen fertilizer types were set in this study, including conventional urea application with zero nitrogen application rate (CK, 0 kg hm-2), nitrogen expert-based fertilization application strategy (NE, 210 kg hm-2), optimized nitrogen fertilizer application strategy recommended by local government (OPT, 240 kg hm-2), and farmer’s experience-based nitrogen fertilizer application strategy (FP, 300 kg hm-2), and controlled-release urea application (CRU, 180 kg hm-2). The data from one growth season field experiment in 2021 revealed the dynamics of nitrogen concentration, paddy yield and its nitrogen uptake characteristic, and nitrogen balance in the paddy field under different nitrogen application practices. Most nitrogen leaching was observed during the seedling and tillering stages in the form of nitrate nitrogen (NO3–N). Compared with the FP, the CRU and OPT significantly reduced the nitrogen concentrations of total nitrogen (TN), ammonium nitrogen (NH4+-N), and NO3–N in the surface and soil water and reduced the nitrogen leaching at 100 cm soil depth. Meanwhile, the paddy grain yield in CRU (7737 kg hm-2) and OPT (7379 kg hm-2) was not significantly decreased compared with FP (7918 kg hm-2), even though the nitrogen uptake by grain and straw was higher in FP (135 kg hm-2) than in other treatments (52.10~126.40 kg hm-2). However, the grain yield in NE (6972 kg hm-2) was decreased compared with the FP. The differences in grain yield among these treatments were mainly attributed to the ear number and grain number changes. Also, the highest nitrogen use efficiency (40.14%), apparent nitrogen efficiency (19.53 kg kg-1), and nitrogen partial productivity (43.98 kg kg-1) were identified in CRU than in other treatments. Considering increased grain yield and reducing nitrogen loss in the paddy field simultaneously, the treatments of CRU (i.e., 180 kg hm-2 nitrogen application rate with controlled-release urea) and OPT (i.e., 240 kg hm-2 nitrogen application rate with conventional urea) were recommended for nitrogen fertilizer application in the study area.

Published: January 2023

Mapping-by-sequencing combines Next Generation Sequencing (NGS) with classical genetic mapping by linkage analysis to establish gene-to-phenotype relationships. Although numerous tools have been developed to analyze NGS datasets, only a few are available for mapping-by-sequencing. One such tool is Easymap, a versatile, easy-to-use package that performs automated mapping of point mutations and large DNA insertions. Here, we describe Easymap v.2, which also maps small insertion/deletions (InDels), and includes workflows to perform QTL-seq and variant density mapping analyses. Each mapping workflow can accommodate different experimental designs, including outcrossing and backcrossing, F2, M2, and M3 mapping populations, chemically induced mutation and natural variant mapping, input files containing single-end or paired-end reads of genomic or complementary DNA sequences, and alternative control sample files in FASTQ and VCF formats. Easymap v.2 can also be used as a variant analyzer in the absence of a mapping algorithm and includes a multi-threading option.
Genes related to osmoregulation and antioxidation play important roles in the response of Trollius chinensis seedlings to saline-alkali stress
Authors: Hou Rongmiao , Yang Lizhi , Wuyun Tana , Chen Shiyao , Zhang Lu
Published: January 2023

Saline-alkali stress is one of the main abiotic stress factors affecting plant growth and development. Trollius chinensis is a perennial herbal medicinal plant with high values for garden application. However, its response and tolerance to saline-alkali stress is unclear. In this study, we mixed four salts (NaCl: Na2SO4: NaHCO3: Na2CO3) with a concentration ratio of 1:9:9:1, and applied low (40 and 80 mM) and high (120 and 160 mM) saline-alkali stress to analyze osmotic regulation substances, antioxidant systems and the gene expression of T. chinensis. Along with higher saline-alkali stress, the leaf relative water content (RWC) started to decrease only from high stress, while the malondialdehyde (MDA) content in leaves decreased continuously, and the contents of proline (Pro), soluble sugar (SS) and soluble protein (SP) increased compared with control. The activities of antioxidant enzymes and the contents of non-enzymatic antioxidants were increased positively with the accumulation of superoxide anion (O2•–) and hydrogen peroxide (H2O2). For instance, the ascorbic acid-glutathione (AsA-GSH) cycle was enhanced in T. chinensis seedling leaves subject to saline-alkali stress. Principal Component Analysis (PCA) indicates that MDA, Pro, SS, SP, H2O2, O2•–, and GSH are important indexes to evaluate the response and tolerance of T. chinensis to saline-alkali stress. Through RNA-Seq, a total of 474 differentially expressed genes (DEGs) were found in plant under low saline-alkaline stress (40 mM, MSA1) vs. control. Among them, 364 genes were up-regulated and 110 genes were down-regulated. DEGs were extensively enriched in carbohydrate transport, transferase activity, zeatin biosynthesis, ABC transporters, and spliceosome. The transcription factor family MYB, BZIP, WRKY, and NAC were related to its saline-alkali tolerance. In addition, some DEGs encode key enzymes in the processes of osmoregulation and antioxidation, including betaine aldehyde dehydrogenase (BADH), inositol monophosphatase (IMP), chloroperoxidase (CPO), thioredoxin (Trx), and germin-like protein (GLPs) were found. Overall, these findings provide new insights into the physiological changes and molecular mechanism of T. chinensis to saline-alkali stress and lay a foundation for application of T. chinensis in saline-alkali environment.

Published: January 2023

Morphological and molecular characterization of germplasm is essential for the improvement of cultivated plants efforts. This study investigated the genetic diversity of 32 Cyclamen genotypes comprising 16 C. persicum varieties and 16 Cyclamen species using multivariate analysis for 36 morphological traits (19 quantitative and 17 qualitative) and molecular characterization (SRAP and SCoT markers). The color CIELab parameters were collected via PCE-CSM7 that separately measured the leaves dark and silvery patterns and the flower’s slip (region of the petal top), eye (the region of the petal base) and sepal. Genetic diversity was also evaluated using Shannon Wiener (H′) and Simpson’s (λ) Indices, and Pilou evenness (J) using the library vegan from R software. According to the principal component analysis, the variables that contributed the most were leaf pattern color, leaf abaxial surface color, pedicel coiling, leaf and stem number. The color indicators of Cyclamen leaves showed decreased L* values in darker colored genotypes, whereas increased a* values were noticed in flower eye and lower in slip. Molecular characterization was based on 26 SRAP and 12 SCoT markers that produced clearly repeatable DNA bands and exhibited significant levels of polymorphism. Based on the morphological traits and molecular markers data, the UPGMA method for hierarchical clustering technique was used to generate the dendrograms, and their entanglement was obtained using the Tanglegram algorithm from the dendextend package with the R software. Entanglement analysis (0.30) between dendrograms obtained from the morphological and genetic analysis using SRAP markers showed a high association. Comparison between color measurements of flowers (entanglement=0.45) and leaves (entanglement=0.47) with SCoT analysis revealed differences at species level, discriminating between similar genotypes. Combined phenotypic and molecular analysis improved the comprehensive estimation of real diversity in the investigated Cyclamen genotypes. The findings of the present study are useful for quantifying diversity and genetic variability in Cyclamen breeding and genetic investigations.

Published: January 2023

Southern corn rust (SCR), caused by Puccinia polysora Underw, is a destructive disease that can severely reduce grain yield in maize (Zea mays L.). Owing to P. polysora being multi-racial, it is very important to explore more resistance genes and develop more efficient selection approaches in maize breeding programs. Here, four Doubled Haploid (DH) populations with 384 accessions originated from selected parents and their 903 testcross hybrids were used to perform genome-wide association (GWAS). Three GWAS processes included the additive model in the DH panel, additive and dominant models in the hybrid panel. As a result, five loci were detected on chromosomes 1, 7, 8, 8, and 10, with P-values ranging from 4.83×10-7 to 2.46×10-41. In all association analyses, a highly significant locus on chromosome 10 was detected, which was tight chained with the known SCR resistance gene RPPC and RPPK. Genomic prediction (GP), has been proven to be effective in plant breeding. In our study, several models were performed to explore predictive ability in hybrid populations for SCR resistance, including extended GBLUP with different genetic matrices, maker based prediction models, and mixed models with QTL as fixed factors. For GBLUP models, the prediction accuracies ranged from 0.56-0.60. Compared with traditional prediction only with additive effect, prediction ability was significantly improved by adding additive-by-additive effect (P-value< 0.05). For maker based models, the accuracy of BayesA and BayesB was 0.65, 8% higher than other models (i.e., RRBLUP, BRR, BL, BayesC). Finally, by adding QTL into the mixed linear prediction model, the accuracy can be further improved to 0.67, especially for the G_A model, the prediction performance can be increased by 11.67%. The prediction accuracy of the BayesB model can be further improved significantly by adding QTL information (P-value< 0.05). This study will provide important valuable information for understanding the genetic architecture and the application of GP for SCR in maize breeding.

Authors: Li Shujing , Li Zhangfei , Li Qinghe , Zhang Mingyu , Li Linguo
Published: January 2023

With the development and wider application of meta-heuristic optimization algorithms, researchers increasingly apply them to threshold optimization of multi-level image segmentation. This paper explores the performance and effects of Capuchin Search Algorithm (CAPSA) in threshold optimization. To solve problems of uneven distribution in the initial population of Capuchin Search Algorithm, low levels of global search performance and premature falling into local optima, this paper proposes an improved Capuchin Search Algorithm (ICAPSA) through a multi-strategy approach. ICAPSA uses chaotic opposite-based learning strategy to initialize the positions of individual capuchins, and improve the quality of the initial population. In the iterative position updating process, Levy Flight disturbance strategy is introduced to balance the global optimization and local exploitation of the algorithm. Finally, taking Kapur as the objective function, this paper applies ICAPSA to multi-level thresholding in the plant images, and compares its segmentation effects with the original CAPSA, the Fuzzy Artificial Bee Colony algorithm (FABC), the Differential Coyote Optimization Algorithm (DCOA), the Modified Whale Optimization Algorithm (MWOA) and Improved Satin Bowerbird Optimization Algorithm (ISBO). Through comparison, it is found that ICAPSA demonstrates superior segmentation effect, both in the visual effects of image segmentation and in data comparison.
Distrusted disclosures: Deception drives anti-transgender but not anti-atheist prejudice
Authors: Totton Rebecca R. , Rios Kimberly , Shogren Nathaniel
Published: January 2023

Introduction

Transgender individuals face high levels of prejudice in interpersonal relationships. However, limited experimental research has examined the role of identity disclosure on anti-transgender prejudice.

Methods

Drawing upon research on distrust and identity disclosure, two between-participants experiments (total n = 802) examined the role of intentional and unintentional identity disclosure on negative attitudes (Studies 1 & 2), perceived deception (Studies 1 & 2) and distrust (Study 2) toward two potentially concealable and historically distrusted identities (transgender and atheist). Specifically, the current studies examine the impact of a target’s stigmatized identity (transgender or atheist) and method of disclosure (intentional or unintentional) on perceptions of the target, perceived deceptiveness, and distrust toward the target.

Results

Our findings demonstrated that compared to atheists, transgender targets elicited greater levels of prejudice and were viewed as more deceptive, and that this effect was amplified if the target did not intentionally reveal their identity. Study 2 demonstrated that perceived deception mediated the relationship between reveal type (i.e., intentional vs. unintentional) and prejudice toward participants who read about a transgender (but not atheist) target.

Discussion

We discuss the implications of these findings for reducing prejudice toward binary transgender individuals, particularly those who do not voluntarily disclose their identity.
Bad apples spoiling the metaphor? How and why self-serving leaders stir up counterproductive behaviors at work
Authors: Zhang Yajun , Peng Shuai , Wang Jinsong , Akhtar Muhammad Naseer , Wang Yongqi
Published: January 2023

Self-serving leaders satisfy their self-interests at the cost of both employees and organizations, leading to declining organizational competitive advantage and performance. Drawing upon the affective events theory (AET), we constructed and examined a theoretical model of self-serving leadership influencing counterproductive work behavior (CWB), where traditionality plays a significant moderating role through the lens of anger as a mediator. Data were collected in three waves using a survey questionnaire distributed in three industries located in the Southwest district of China. Hierarchical regression analyses were conducted on a sample of 316 employees to test the hypothesized research model. The results showed that self-serving leadership triggers employee anger, which in turn causes CWB. Furthermore, traditionality plays a significant moderating role, in which employees with higher levels of traditionality feel less anger and show less CWB. Overall, research findings have clarified how and why self-serving leadership affects employees’ emotions (such as anger) and behavior (such as CWB), bringing new insights into the self-serving leadership and employee behavior literature. Research implications on the management of self-serving leadership, limitations, and future recommendations of research are also discussed.
Government crisis communication innovation and its psychological intervention coupling: Based on an analysis of China’s provincial COVID-19 outbreak updates
Authors: Zhou Shen , Yu Wensheng , Tang Xinwen , Li Xiaoqian
Published: January 2023

Outbreak updates are an integral part of crisis communication during epidemics. Regarding the COVID-19 crisis communication, localities in China present different strategies for managing outbreak updates, which largely determine the effect of crisis communication and the evolution of social psychology. Depending on the analysis of the update texts from 31 provincial (autonomous regions and municipalities directly under the central government) health committees in China, the study found the differences among the provincial outbreak updates and summarizes 12 innovative crisis communication ways. A coupling analysis was applied using the equilibrium-cognitive-psychosocial transition model to further expound on the psychological connotation and intervention potential of the crisis communication innovations. Coupling crisis communication with interventions has a positive effect on designing crisis communication strategies by taking into account psychological factors. It can help construct and optimize the public crisis communication systems and emphasize “care” in modernizing the emergency management capacity.

Published: January 2023

Background

Patients with chronic wounds experience various biopsychosocial problems which severely affects their quality of life (QoL). Thus, a Persian instrument to assess the QoL of these patients is required. This study aimed to determine the psychometric properties of the Persian version of the wound-QOL questionnaire.

Methods

This methodological study was performed on Iranian patients during 2021–2022. The translation was carried out via forward-backward method. Face validity was addressed with 10 patients and content validity with 12 wound specialists. Construct validity was also assessed by performing exploratory factor analysis (EFA) (n = 100) and convergent validation with EQ-5D-3L plus Pain VAS Score and known-groups validity. The reliability was assessed by internal consistency using Cronbach’s alpha coefficient and test–retest.

Results

A total of 100 patients with chronic wounds were included in the study. Two factors with cumulative variance of 65.39% were extracted during EFA. The results revealed a significant and high correlation between the total scores of wound-QOL questionnaire, the Persian version of EQ-5D-3L (p = 0.000, r = 0.502), and Pain score (0–10; p = 0.000, r = 0.627). The Cronbach’s alpha was 0.743 and stability of the questionnaire (α = 0.872) was confirmed. In confirming the known-groups validity, the results showed that this tool can differentiate the QOL of patients with different wounds.

Conclusion

The Persian version of the wound-QOL questionnaire is a valid and reliable questionnaire which can measure the QoL of patients with chronic wounds. This instrument can be used in clinical evaluation as well as research purposes across the Iranian population.

Published: January 2023

Background

This study aimed to investigate the relationships between regional neural activity and multiple related indicators in patients with major depressive disorder (MDD).

Methods

Forty-two patients and 42 healthy controls (HCs) were enrolled. Pearson/Spearman correlation analyses were applied to examine the associations between abnormal regional homogeneity (ReHo) and different indicators in the patients.

Results

Compared with HCs, patients with MDD had increased ReHo in the left inferior temporal gyrus (ITG) and decreased ReHo values in the left putamen, anterior cingulate cortex (ACC), and precentral gyrus. The ReHo of the left putamen was positively correlated with the PR interval, Repeatable Battery for the Assessment of Neuropsychological Status 4A, and Discriminant analysis (D), and negatively correlated with Ae (block) and Ae (total) in the patients. The ReHo value of the left ACC was positively correlated with the severity of depression, Stroop Color Word Test of C − 2B + 100 in reaction time, and negatively correlated with Ce (Missay) and Perseverative Responses in the patients. The ReHo of the left ITG was positively correlated with the Neuroticism scores and negatively correlated with the Lie scores in the patients.

Conclusion

These results suggested that the decreased ReHo of the salience network might be the underpinning of cognitive impairments in patients with MDD.
The impact of transformational leadership on the turnover intention of the new generation of knowledgeable employees: A moderated mediation model
Authors: Xiong Bin , Wu Xiaoyan , Sui Qi
Published: January 2023

The relationship between transformational leadership and employee behavior has been a popular topic in organizational research. However, while various factors have been identified for the influence of transformational leadership on employee behavior, researchers have so far failed to explore the impact of transformational leadership on the turnover propensity of the new generation of knowledge workers in terms of a specific orientation. Based on the social exchange theory, this study explored the influence of transformational leadership on the turnover intention of the new generation of knowledgeable employees, considering the mediating role of person–organization fit and the moderating role of job embeddedness. Through using SPSS 25.0, Amos 24.0, and PROCESS 3.3 to analyze the data of 326 workers, the results showed that transformational leadership has a negative predictive effect on the turnover intention of the new generation of knowledgeable employees. Person–organization fit plays a partial mediating role between transformational leadership and the turnover intention of the new generation of knowledgeable employees. The relationship between transformational leadership and person–organization fit is positively moderated by job embeddedness. Therefore, there is a moderated mediation model between transformational leadership and the new generation of knowledgeable employees. This research is a good reference and guide for management practices between transformational leadership and the new generation of knowledge workers.
Factors affecting consumer attitudes towards using digital media platforms on health knowledge communication: Findings of cognition–affect–conation pattern
Authors: Zeng Siqi , Lin Xinyi , Zhou Liting
Published: January 2023

As the world enters the second year of the pandemic, many posts are marketed to promote products under the guise of spreading knowledge to fulfill the users’ requirement for health knowledge. Current research, however, has primarily focused on methods to improve health literacy rather than the impact of this new form. To remedy this deficiency, this research use Cognition–Affect–Conation Pattern (CAC) to investigate digital media users and to determine attitudes towards this new form and influential. Data was collected in December 2021 from 314 users in Guangzhou, China, via a Likert-type scale developed by the researchers. Regression analyzes were also performed. Research has shown that consumer attitudes in health knowledge marketing fall within the standard learning hierarchy, with consumer self-cognition and information quality cognitions showing a positive relationship with their affect and conation. At the same time, affect did play a mediating role in this model. The results of our study provide constructive solutions for companies to optimize the communication environment of health spread in society. The findings not only provide researchers with a new perspective to study the impact of interactive digital media communication on health knowledge, but also help identify users’ information needs and formulate effective strategies to increase consumers’ understanding and application of health knowledge and products. Providing health knowledge content and leveraging digital media to develop well-established communication channels is important to foster relationships with customers.
‘Looking before and after’: Can simple eye tracking patterns distinguish poetic from prosaic texts?
Authors: Corcoran Rhiannon , de Bezenac Christophe , Davis Philip
Published: January 2023

Introduction

The study of ‘serious’ literature has recently developed into an emerging field called neurocognitive poetics that applies cognitive neuroscientific techniques to examine how we understand and appreciate poetry. The current research used eye-tracking techniques on a small sample of young adults to see if and how the reading of short pieces of poetry differed from the reading of matched prosaic texts.

Methods

With ‘proof of concept’ intentions reflecting arguments first proposed by 19th Century literary figures, there was a particular focus on the differences between the reading of poetry and prose in terms number and frequency of fixations and regressive eye movements back and forth within the texts in this two-by-two experimental design (poetry vs. prose x need vs. no need for final line reappraisal).

Results

It was found that poetic pieces compared to prosaic pieces were associated with more and longer fixations and more regressive eye movements throughout the text. The need to reappraise meaning at the prompt of a final line was only significantly associated with more regressive eye movements. Comparisons examining the 4 text conditions (poetic reappraisal, poetic non-reappraisal, prosaic reappraisal, and prosaic non-reappraisal) showed that the poetic reappraisal condition was characterised by significantly more regressive eye movements as well as longer fixations compared to the prosaic non-reappraisal condition. No significant correlations were found between self-reported literary familiarity and eye tracking patterns.

Discussion

Despite limitations, this proof-of-concept study provides insights into reading patterns that can help to define objectively the nature of poetic material as requiring slower reading particularly characterised by more and longer fixations and eye movements backwards through the texts compared to the faster, more linear reading of prose. Future research using these, and other psychophysiological metrics can begin to unpack the putative cognitive benefits of reading literary material.
Cross-modal correspondence enhances elevation localization in visual-to-auditory sensory substitution
Authors: Bordeau Camille , Scalvini Florian , Migniot Cyrille , Dubois Julien , Ambard Maxime
Published: January 2023

Introduction

Visual-to-auditory sensory substitution devices are assistive devices for the blind that convert visual images into auditory images (or soundscapes) by mapping visual features with acoustic cues. To convey spatial information with sounds, several sensory substitution devices use a Virtual Acoustic Space (VAS) using Head Related Transfer Functions (HRTFs) to synthesize natural acoustic cues used for sound localization. However, the perception of the elevation is known to be inaccurate with generic spatialization since it is based on notches in the audio spectrum that are specific to each individual. Another method used to convey elevation information is based on the audiovisual cross-modal correspondence between pitch and visual elevation. The main drawback of this second method is caused by the limitation of the ability to perceive elevation through HRTFs due to the spectral narrowband of the sounds.

Method

In this study we compared the early ability to localize objects with a visual-to-auditory sensory substitution device where elevation is either conveyed using a spatialization-based only method (Noise encoding) or using pitch-based methods with different spectral complexities (Monotonic and Harmonic encodings). Thirty eight blindfolded participants had to localize a virtual target using soundscapes before and after having been familiarized with the visual-to-auditory encodings.

Results

Participants were more accurate to localize elevation with pitch-based encodings than with the spatialization-based only method. Only slight differences in azimuth localization performance were found between the encodings.

Discussion

This study suggests the intuitiveness of a pitch-based encoding with a facilitation effect of the cross-modal correspondence when a non-individualized sound spatialization is used.
Parental identity formation in mothers is linked to borderline and depressive symptoms: A person-centered analyses
Authors: Piotrowski Konrad
Published: January 2023

The formation of a stable parental identity is an important developmental task which parents face. Difficulties in this process can significantly decrease the quality of life and hinder the fulfillment of the parental role. The present study analyzed whether parental identity status, based on the three identity processes from the Meeus-Crocetti model, is related to the severity of borderline and depressive symptoms. Four hundred and fifty-nine mothers aged 18–40 (M = 32.41, SD = 5.09) participated in the cross-sectional study. The results of the cluster analysis revealed the existence of five different parental identity statuses: Achievement, Foreclosure, Searching moratorium, Diffussion, and Moratorium. Significant differences were also observed between parents with different statuses in terms of borderline and depressive symptoms. The study confirmed predictions that mental health difficulties among parents co-occur with low identification with parenthood.
Investigating the role of E-commerce marketing capabilities to achieve the strategic performance of tourism firms
Authors: Zhao Jianchun , Zhang Peilin
Published: January 2023

Introduction

This study aims to explore the relationships between strategic performance, e-commerce marketing capabilities (ECMCs), the Internet of Things (IoT) and customer engagement. This study examines the direct association between ECMC and strategic performance. Current research also explores the customer engagement mediation between ECMC and strategic performance (SP). Furthermore, our study investigates the IoT moderation between ECMC and SP.

Methods

We test our research hypotheses using data collected in the tourism sector in the context of digital commerce. The questionnaire is used to collect data through random sampling, and these data are useful as a basis for future research. By adding e-commerce capabilities, we show firms how to become more efficient and improve their strategic performance. Moreover, this study, by incorporating the findings of the existing literature, provides a strong foundation for studying the impact of ECMCs and customer engagement on strategic performance as well as the mediating role of e-trust.

Results

The results can be useful for managers who conduct digital business internationally, as they need to understand the importance of ECMCs. In fact, the adaptation of ECMCs to the organization enhances customer engagement and helps to improve strategic performance.

Discussion

The approach used in this study is in line with previous theoretical analyses and shows emerging patterns in international digital businesses. Moreover, this study adds insights to the e-commerce research by linking different dimensions to reach an in-depth understanding of each item that is affected by ECMCs.
Estimating the prevalence of alcohol-related disorders and treatment utilization in Bremen 2016/2017 through routine data linkage
Authors: Möckl Justin , Lindemann Christina , Manthey Jakob , Schulte Bernd , Reimer Jens , Pogarell Oliver , Kraus Ludwig
Published: January 2023

Background

In Germany, most individuals with alcohol dependence are recognized by the health care system and about 16% per year receive addiction-specific care. This paper aimed to analyze the prevalence and treatment utilization rate of people with alcohol dependence by type of addiction-specific care in the federal state of Bremen using routine and survey data.

Methods

The number of individuals with alcohol dependence was estimated using data from the 2018 Epidemiological Survey of Substance Abuse (ESA). Furthermore, linked routine data of two statutory health insurances (SHIs), the German pension insurance (GPI), and the communal hospital group Gesundheit Nord – Bremen Hospital Group (GeNo), from 2016/2017, were analyzed. Based on SHI data, the administrative prevalence of various alcohol-related diagnoses according to the International Classification of Diseases (ICD-10), in various treatment settings, was extrapolated to the total population of Bremen. Based on all routine data sources, treatment and care services for individuals with alcohol dependence were also extrapolated to Bremen’s total population. Care services included outpatient addiction care visits and addiction-specific treatments, [i.e., qualified withdrawal treatment (QWT), outpatient pharmacotherapy as relapse prevention, and rehabilitation treatment].

Results

Of the survey-estimated 15,792 individuals with alcohol dependence in Bremen, 72.6% (n = 11,467) had a diagnosis documented with an ICD-10 code for alcohol dependence (F10.2) or withdrawal symptoms (F10.3–F10.4). One in ten individuals with alcohol dependence (n = 1,689) used one or more addiction-specific care services during the observation period. Specifically, 4.3% (n = 675) received outpatient addiction care, 4.7% (n = 736) initiated QWT, 0.8% (n = 133) received pharmacotherapy, and 3.9% (n = 614) underwent rehabilitation treatment. The share of seeking addiction-specific treatment after diagnosis was highest among younger and male patients.

Conclusion

Although more than half of the individuals with alcohol dependence are documented in the health system, utilization rates of addiction-specific treatments are low. These low utilization rates suggest that there are existing barriers to transferring patients with alcohol dependence into addiction-specific care. Strengthening primary medical care provision in dealing with alcohol-related disorders and improving networking within the addiction support system appear to be particularly appropriate.

Introduction

Vaccine hesitancy could undermine efforts to reduce incidence of coronavirus disease 2019 (COVID-19). Understanding COVID-19 vaccine hesitancy is crucial to tailoring strategies to increase vaccination acceptance. This study aims to investigate the prevalence of and the reasons for COVID-19 vaccine hesitancy in Malang District, Indonesia.

Methods

Data come from a cross-sectional study among individuals aged 17-85 years old (N = 3,014). Multivariate ordered logistic regression was used to identify factors associated with postponing or refusing COVID-19 vaccines. The Oxford COVID-19 vaccine hesitancy scale was used to measure vaccine hesitancy. A wide range of reasons for hesitancy, including coronavirus vaccine confidence and complacency, vaccination knowledge, trust and attitude in health workers and health providers, coronavirus conspiracy, anger reaction and need for chaos, populist views, lifestyle, and religious influence, was examined.

Results and discussion

The results show that 60.2% of the respondents were hesitant to receive the COVID-19 vaccine. Low confidence and complacency beliefs about the vaccine (OR = 1.229, 95% CI = 1.195–1.264) and more general sources of mistrust within the community, particularly regarding health providers (OR = 1.064, 95% CI = 1.026–1.102) and vaccine developers (OR = 1.054, 95% CI = 1.027–1.082), are associated with higher levels of COVID-19 vaccine hesitancy. Vaccine hesitancy is also associated with anger reactions (OR = 1.019, 95% CI = 0.998–1.040), need for chaos (OR = 1.044, 95% CI = 1.022–1.067), and populist views (OR = 1.028, 95% CI = 1.00–1.056). The findings were adjusted for socio-demographic factors, including age, sex, education, marital status, working status, type of family, household income, religious beliefs, and residency. The results suggest the need for an effective health promotion program to improve community knowledge of the COVID-19 vaccine, while effective strategies to tackle “infodemics” are needed to address hesitancy during a new vaccine introduction program.

Because of the world's dependence on fossil fuels, climate change and air pollution are profoundly harming both human and planetary health. Fortunately, climate solutions are also health solutions, and they present both local and global opportunities to foster cleaner, healthier, and safer communities. In this review, we briefly discuss the human health harms of climate change, climate and health solutions, and provide a thorough synthesis of social science research on climate and health communication. Through our review, we found that social science research provides an evidence-based foundation for messaging strategies that can build public and political will for climate and health solutions. Specifically, messages that convey the health harms of climate change and highlight the health benefits of climate solutions may be especially effective in building this public and political will. We also found that health professionals are trusted sources of information about climate change, and many have shown interest in engaging with the public and policymakers about the health relevance of climate change and clean energy. Together, the alignment between message strategies and the interest of highly trusted messengers strongly suggests the potential of health students and health professionals to create the conditions necessary to address climate change as a public health imperative. Therefore, our review serves as a resource for those interested in communicating about climate change and health and suggests that social scientists can continue to support practitioners with research and advice on the most effective communication strategies.

Introduction

It has become a common contemporary phenomenon for grandparents to provide care for young children in their family in both urban and rural areas. This study attempted to investigate psychological wellbeing and quality of life among grandparents involved in childcare in China, and to explore the relationships between sociodemographic characteristics, quality of life, and life satisfaction in this group.

Methods

Using stratified random cluster sampling, we conducted a survey of grandparent caregivers in Wuhan in November and December of 2020 (N = 1,640). Descriptive statistics to univariate analysis, multiple linear regression, and structural equation modeling were carried out.

Results

Across all respondents, mean scores on life satisfaction, sleep quality, and quality of life were 14.05 ± 3.50, 5.02 ± 3.37, and 74.51 ± 16.88, respectively. Marital status, income, chronic diseases, family relationships, and physical exercise were found to be associated with life satisfaction. The results of structural equation modeling indicated that quality of life, sleep quality, and sociodemographic characteristics may exert direct and indirect effects on life satisfaction. Mediating effects accounted for 30.0% of the total effects.

Conclusion

Overall, grandparent caregivers have poor life satisfaction, quality of life, and sleep quality. A higher household income, better relationships with family members, healthy lifestyle habits, and high-quality sleep may effectively help to improve life satisfaction among grandparent caregivers.
Preferences for public long-term care insurance among middle-aged and elderly residents: A discrete choice experiment in Hubei Province, China

Objective

It is critical to incorporate residents' preferences into the design of long-term care insurance (LTCI). However, little is known about middle-aged and elderly residents' preferences for personalized need-related attributes of LTCI in China. Through a discrete choice experiment (DCE), we aimed to focus on the direct beneficiaries of LTCI and then elicit their preferences for LTCI under a hypothetical scenario of dysfunction.

Methods

Attributes and levels were defined through a literature review and two rounds of expert consultations (n = 8). A D-optimal fractional factorial design was used to generate the DCE questionnaire. Face-to-face interviews with middle-aged and elderly residents were conducted in two cities in Hubei Province, China, between November and December 2020. A mixed logit model was utilized for estimation.

Results

Five attributes were identified and incorporated into the DCE questionnaire. A total of 390 participants completed DCE questionnaires. Care facilities, care content, reimbursement rate, caregivers, and annual premium per person all had a significant impact on residents' preferences. Residents had significantly higher preferences for the LTCI scheme with home and community-based care centers (β = 1.40, p < 0.01), multi-level services (β = 0.44, p < 0.01), 90% reimbursement rate (β = 0.37, p < 0.01), and sufficiently trained caregivers (β = 0.26, p < 0.01). Individual characteristics, such as gender, employment, and education level were the factors that drove heterogeneity in preferences for LTCI.

Conclusion

This study provides new evidence on the preferences of middle-aged and elderly residents for personalized need-related public LTCI features. The design of the LTCI scheme in China needs to take these findings into account to maximize the utility for direct beneficiaries of LTCI and enhance their enrollment.

Aims

To assess emergency department (ED) nurses' ability to communicate with angry patients and to explore the factors that influence nurses' communication skills.

Design

A cross-sectional survey design.

Methods

This study was conducted in November and December 2020. Stratified sampling was adopted to recruit ED nurses from 18 tertiary hospitals in western, eastern, and central China to complete an online questionnaire. The Nurses' Communication Ability with Angry Patients Scale (NCAAPS) and the General Self-Efficacy Scale were used to assess ED nurses' communication ability and self-efficacy, respectively. Descriptive statistics, the Mann–Whitney U-test, the Kruskal–Wallis H test, Spearman's correlation analysis, and the generalized linear model were used for data analysis.

Results

A total of 679 valid questionnaires were collected. The mean total score for the NCAAPS was (3.79 ± 0.47), while the scores for its four dimensions were (3.87 ± 0.59) for communication skills, (3.82 ± 0.59) for anger perception, (3.79 ± 0.53) for self-preparation, (3.73 ± 0.54) for exploring the cause of anger. The generalized linear regression analysis result showed that a longer employment duration, previous communication ability training, and higher self-efficacy were significantly and independently associated with higher NCAAPS scores (p < 0.05).

Conclusions

The mean total score and the four dimensions score for the NCAAPS were moderate. But there is still room for improvement in ED nurses' ability to communicate with angry patients. “Exploring the cause of anger” was the lowest score among the four dimensions. To improve ED nurses' ability to communicate with angry patients, future studies should focus on constructing specific communication training, improving nurses' ability to explore the cause of anger and self-efficacy.

Impact

The findings of this study provide important insights into ED nurses' ability to communicate with angry patients and can thus guide the future development of intervention programmes to improve this ability among ED nurses.
