The body size and age of small yellow croaker decreased substantially, in particular, average length of fish in 2008 was reduced by ~85% than those occurring in 1985, and at that time ~93% of the total catch was dominated by one-year-old individuals. Correspondingly, growth parameters also varied significantly over the years, i.e., k(growth coefficient) and t_0(zero-length age) gradually increased from 0.26 and –0.58 year in 1960 to 0.56 and –0.25 year in 2008, respectively. Although, L∞(body length)sharply decreased from 34.21 cm in 1960 to 24.06 cm in 2008, and t_r(inflexion age) decreased from 3.78 year in1960 to 1.61 year in 2008. There was a great increase both in natural mortality coefficient and fishing mortality coefficient. However, according to the gray correlation analysis, changes in the biological characteristics of small yellow croaker were induced by different stressors ranked as: fishing vessel power>feeding grade>sea surface temperature. This study suggests that the active fishery management measures for biological characters of fish populations should be considered.展开更多

Methods: In order to examine this question, we selected 43 patients with lupus whose symp-toms worsened due to the effects of daily stress. These patients were divided into two groups: patients whose increase in clinical lupus symp-tomatology was predicted by an increase in daily stressors on the same day (G1) and pa-tients whose increase in clinical lupus symp-tomatology was predicted by an increase in daily stressors the day before and the same day (G2). Later, three factorial analyses were con-ducted with the items related to stressors and the items related to lupic symptoms. Results: The results showed that in G1 there were three factors that made up a total of 35.08% of the explained variance. The stressors associated with certain symptoms of the illness in this group are feeling ill or being worried about their physical appearance, with the main stressor being the illness itself. However, in G2, two factors were found that made up a total of 40.37% of the explained variance for lag=0 and 38.67% for lag=1. The stressors associated with the majority of the lupus symptoms are of an interpersonal and work-related nature. This as-sociation was maintained when we carried out the factorial analyses with the items of the symptoms from the following day. Conclusions: The interpersonal and work-related stressors are related to a worsening in the majority of the lupic symptoms in the patients whose sympto-matology worsens as a result of daily stress experienced the day before.展开更多

This study examined the relationship between job strain and workplace stressors with psychological distress among employed breast cancer survivors after the completion of their medical treatment. Study subject were outpatients of 2 hospitals and members of 4 breast cancer support groups. They were requested to fill up the Job Content Questionnaires (JCQ), the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) were filled up by the selected respondents. On simple logistic regression, psychological job demand and job strain were significantly associated with anxiety, distress on HADS-T and DT at (p < 0.001). While, psychological job demand (p < 0.001), social support (p = 0.047) and job strain (p < 0.001) were significantly associated with depression. Results showed survivors with high job strain has 4.74 time the odds of having anxiety (p < 0.001). Survivors with high psychological job demand have 8.08 time the odds of getting depression (p < 0.001). On the other hand, social support served as a protective factor of depression, (p = 0.041). Survivors with high psychological job demand were 4.4 time the odds of having distress (HADS-T) (p = 0.012). As a conclusion, survivors who experienced high psychological job demand, low social support and high job strain were reported with anxiety, depression or psychological distress.展开更多

Job stress can be as a result of the nature of the job (work) or can result from the workers commonly referred to as dispositional stress. Stressors are conditions or situations which trigger stress response. Stressors can be inherent in the job due to factors affecting the occupation. This paper therefore highlights impact of technological stress (technostress) in auditing firm in developing countries.展开更多

Consequently, psychological health initiatives are essential to support nurses during a pandemic. This project aims to investigate the stress levels and identify the Coping Strategies of Nurses during the COVID-19 Epidemic in Sharjah Primary Health Center, as they are always at the front line of this epidemic. The nature of their work, they are mainly infected and spread the virus amongst colleagues and family. The target population is nurses working in Sharjah primary health centers, and the number sample is 230. The researcher sent the survey through the link. And in this research, we used two instruments which include the Expanded Nursing Stress Scale and The Coping Strategies Scale (CSS). This study shows that the most stressful factor is related to workload, especially related to unpredictable staffing and scheduling. On the other hand, the most coping strategies were those that were associated with Meaning-focused Coping Strategies, especially believing that valuable lessons can learn from undesirable experiences.展开更多

There are many articles which have been published on the genetic sequencing, pathology and other medical conditions associated with COVID-19, however, there are very few articles which acknowledge the psychological and behavioral aspects of front-line medical workers especially nurses. The purpose of the study is to understand the stressors, psychological behavior status and the correlation between psychological behavior and stressors for nurses who served in COVID-19 ward. The general information questionnaire, the nurse job stressor scale in Chinese, and the emergency public health incident questionnaire were used to survey 282 nurses in Jingzhou Central Hospital who supported COVID-19 ward. The result shows that the average work stress of nurses in this study was 1.40 ± 0.54 points. The top 3 dimensions were conceptual stress (1.67 ± 0.68), working environment stress (1.57 ± 0.60), and occupational hazard stress (1.57 ± 0.66). With different marital status, the average scores of stress are different, and the difference is statistically significant (t = 2.139, P = 0.034). For nurses in COVID-19 ward who faced sudden public health crisis, the self-evaluated psychological score of nurses in COVID-19 ward averages 1.40 with a deviation of 0.54. In our study, fear had the highest influence on psychological behavior, while the lowest was the compulsive-anxiety factor. There was a positive correlation between the stressor scores and the psychological behavior scores (P < 0.01). The conclusion is that the pressure of nurses supporting COVID-19 ward is under moderate pressure, and the psychological behavior is moderately responded with a few nurses having psychological behavior deviation.展开更多

Although some patients can be cured, many do not benefit enough from the psychological therapies or medication strategies used. Many researchers use animal models to learn more about the disorder and several models are available. The most-used physical stressor models are single-prolonged stress, restraint stress, foot shock, stress-enhanced fear learning, and underwater trauma. Common social stressors are housing instability, social instability, earlylife stress, and social defeat. Psychological models are not as diverse and rely on controlled exposure to the test animal's natural predator. While validation of these models has been resolved with replicated symptoms using analogous stressors, translating new findings to human patients remains essential for their impact on the field. Choosing a model to experiment with can be challenging; this overview of what is possible with individual models may aid in making a decision.展开更多

Specific techniques were used to study the impact of UV radiation (Pre and Post UV exposure) on the sperm nuclear DNA viz. Aniline blue staining was for detection of immature chromatin. Chromomycin A3 fluorescence staining was used to determine protamine-DNA dissociation by intense fluorescence of protamine deficient sperm cells and neutral comet assay was for evaluation of DNA fragmentation. Statistical analysis was carried out using Student'st-test (GraphPad Prism Version-6). Level of significance was considered atP<0.05.Results: The data revealed that spermatozoa of OAT and MUI cases when exposed to UV-radiation showed higher percentage of immature sperm compared with normal fertile individuals. Higher percentage of Chromomycin A3 fluorescence in OAT and MUI cases revealed impaired DNA-protamine binding with subsequent DNA fragmentation after exposure to UV.Conclusions:In the present study, sperm chromatin is at higher risk of DNA fragmentation in the infertile (OAT and MUI) cases due to UV irradiation (254 nm). Hence, short duration UV exposure is detrimental to sperm DNA which could affect ensuing generations.展开更多

Main anthropogenic disturbances such as habitat size reduction, fire and non-timber forest harvest affect demographic processes but our understanding of their interaction effects in contrasted ecological conditions is limited. We investigated the interaction effects of fruit harvest, fire, gallery forest size and distance to streambed on density, recruitment, survival and growth of Pentadesma butyracea offspring in dry and moist ecological conditions. We randomly selected in each ecological region six P. butyracea populations. We then established in each population, 10 subplots of 100 m2 within 1 ha to assess offspring demographic performance from 2015 to 2017. Results showed that fire suppressed the positive effect of large habitat size and amplified the negative effect of increasing local aridity on offspring growth. Fire and harvest synergistically reduced growth whereas offspring growth was resilient to fire in moist ecological region. Moist ecological conditions mitigated the negative effect of harvest on growth. Harvest mitigated the surprise negative effect of large habitat size on survival. However, in large gallery size, high harvest limited clonal recruitment and growth. There was a positive interaction effect between harvest and distance to streambed on survival (High harvest, Z = 2.045, p = 0.041, Medium, Z = 2.060, p = 0.039) but a negative interaction effect on growth (High, t = -2.357, p 0.05). Clonal offspring grew faster than sexual offspring in high harvest populations. In moist region, offspring survived better in large gallery forest size. In 2017, survival and growth were lower in large gallery forest. In 2017, offspring growth was higher near the riverbed where the survival rate low. This study suggests that management strategies should consider the interaction effects of anthropogenic disturbances and climatic conditions.展开更多

Methods: In order to examine this question, we selected 43 patients with lupus whose symp-toms worsened due to the effects of daily stress. These patients were divided into two groups: patients whose increase in clinical lupus symp-tomatology was predicted by an increase in daily stressors on the same day (G1) and pa-tients whose increase in clinical lupus symp-tomatology was predicted by an increase in daily stressors the day before and the same day (G2). Later, three factorial analyses were con-ducted with the items related to stressors and the items related to lupic symptoms. Results: The results showed that in G1 there were three factors that made up a total of 35.08% of the explained variance. The stressors associated with certain symptoms of the illness in this group are feeling ill or being worried about their physical appearance, with the main stressor being the illness itself. However, in G2, two factors were found that made up a total of 40.37% of the explained variance for lag=0 and 38.67% for lag=1. The stressors associated with the majority of the lupus symptoms are of an interpersonal and work-related nature. This as-sociation was maintained when we carried out the factorial analyses with the items of the symptoms from the following day. Conclusions: The interpersonal and work-related stressors are related to a worsening in the majority of the lupic symptoms in the patients whose sympto-matology worsens as a result of daily stress experienced the day before.
文摘Evidence showed occupational factors may contribute distress to breast cancer survivors, however, very few studies focused on the occupational factors and job strain among breast cancer survivors. This study examined the relationship between job strain and workplace stressors with psychological distress among employed breast cancer survivors after the completion of their medical treatment. Study subject were outpatients of 2 hospitals and members of 4 breast cancer support groups. They were requested to fill up the Job Content Questionnaires (JCQ), the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) were filled up by the selected respondents. On simple logistic regression, psychological job demand and job strain were significantly associated with anxiety, distress on HADS-T and DT at (p < 0.001). While, psychological job demand (p < 0.001), social support (p = 0.047) and job strain (p < 0.001) were significantly associated with depression. Results showed survivors with high job strain has 4.74 time the odds of having anxiety (p < 0.001). Survivors with high psychological job demand have 8.08 time the odds of getting depression (p < 0.001). On the other hand, social support served as a protective factor of depression, (p = 0.041). Survivors with high psychological job demand were 4.4 time the odds of having distress (HADS-T) (p = 0.012). As a conclusion, survivors who experienced high psychological job demand, low social support and high job strain were reported with anxiety, depression or psychological distress.
文摘Teaching is a stressful profession characterizing the work of teachers.The Neoliberal reforms have added a further burden on teachers’work,increasing stress at work and resulting in negative health,occupational and economic consequences.The aims of the study were to examine the perceptions of stress factors among Arab teachers in Israel,and the relationship between Arab teachers’stress factors by types of school(elementary,middle school,and high school)and gender.Stress factors were measured by using an instrument developed by Ablin et al.(2010).Three hundred forty-two public school Arab teachers participated in the study,of whom 230 were female and 112 were male.One hundred twenty-five worked in elementary schools,78 in middle schools,and 130 in high schools.The most stressful factors among Arab teachers were“busy schedule and lack of flexibility”,“the student composition of the class”,and“conflicting requirements between school assignments and home responsibilities”.Significant statistical differences were found between teachers’stress factors by gender and school type.Female teachers rated stress factors“the student composition of the class”and“conflicting requirements between school assignments and home responsibilities”higher than male teachers.Elementary teachers rated stress factors“student parents”,“lack of proper physical conditions”,and“requirement to teach a subject other than one’s specialty”higher than high school teachers.Middle school teachers rated stress factors“school management”,“general supervisor”,and“requirement to teach a subject other than one’s specialty”higher than primary school teachers.The leading stressor in this study is a result of educational disparities between Jews and Arabs.Israel formally purports to embrace the liberal responsibility of providing educational and development opportunities to all of its citizens,enabling them to actualize their full potential as human beings.
文摘Stress as a state of anxiety is produced when responsibilities do not match expected knowledge, and hence challenges one’s coping abilities. Job stress can be as a result of the nature of the job (work) or can result from the workers commonly referred to as dispositional stress. Stressors are conditions or situations which trigger stress response. Stressors can be inherent in the job due to factors affecting the occupation. This paper therefore highlights impact of technological stress (technostress) in auditing firm in developing countries.
文摘During the COVID-19 Epidemic, nurses are usually informed of emotional exhaustion, increased workloads, and uncertainty, leading to burnout. Consequently, psychological health initiatives are essential to support nurses during a pandemic. This project aims to investigate the stress levels and identify the Coping Strategies of Nurses during the COVID-19 Epidemic in Sharjah Primary Health Center, as they are always at the front line of this epidemic. The nature of their work, they are mainly infected and spread the virus amongst colleagues and family. The target population is nurses working in Sharjah primary health centers, and the number sample is 230. The researcher sent the survey through the link. And in this research, we used two instruments which include the Expanded Nursing Stress Scale and The Coping Strategies Scale (CSS). This study shows that the most stressful factor is related to workload, especially related to unpredictable staffing and scheduling. On the other hand, the most coping strategies were those that were associated with Meaning-focused Coping Strategies, especially believing that valuable lessons can learn from undesirable experiences.

文摘The study aimed to investigate the influence of academic stressors on mental health and the mediating effect of social support and self-identity among college students and further studied the difference between the graduating students and non-graduating students during the COVID-19 Pandemic.Recruiting 900 college students as sub-jects,used the college students’academic stressors questionnaire,social support questionnaire,self-identity scale and depression anxiety stress scales(DASS-21).The results showed that:(1)The college students’academic stressor posi-tively predicted mental health;(2)Social support and self-identity mediated the relationship;(3)The model also held when academic stressors was replaced by work stressor,but there were differences between the graduating and non-graduating students;(4)The direct effect work stressor on mental health in the graduating group was not significant;(5)The non-graduating students’work stressor could not predict mental health through social support.
文摘Background:People with mental disorders often experience human rights violations,discrimination,exclusion,and stigma.Objective:To determine the stressors and coping mechanisms of people with mental disorders in society.Methods:This research is a qualitative phenomenological research.We wanted to explore and describe the experiences of mentally ill patients in the community at the rehabilitation stage in stress management,including the stressors in people with a mental health condition and the coping mechanisms used.Data collection was carried out using in-depth interviews with 15 participants.Results:The results of this study show that the stressors of mental illness patients are a less-accepting environment,feeling of shame,fear of being excluded,having no income,and side effects of drugs.Conclusions:The coping mechanisms used include carrying out activities,telling stories to others,and diverting emotions.
文摘COVID-19 has been a hot topic of research in medical journals. There are many articles which have been published on the genetic sequencing, pathology and other medical conditions associated with COVID-19, however, there are very few articles which acknowledge the psychological and behavioral aspects of front-line medical workers especially nurses. The purpose of the study is to understand the stressors, psychological behavior status and the correlation between psychological behavior and stressors for nurses who served in COVID-19 ward. The general information questionnaire, the nurse job stressor scale in Chinese, and the emergency public health incident questionnaire were used to survey 282 nurses in Jingzhou Central Hospital who supported COVID-19 ward. The result shows that the average work stress of nurses in this study was 1.40 ± 0.54 points. The top 3 dimensions were conceptual stress (1.67 ± 0.68), working environment stress (1.57 ± 0.60), and occupational hazard stress (1.57 ± 0.66). With different marital status, the average scores of stress are different, and the difference is statistically significant (t = 2.139, P = 0.034). For nurses in COVID-19 ward who faced sudden public health crisis, the self-evaluated psychological score of nurses in COVID-19 ward averages 1.40 with a deviation of 0.54. In our study, fear had the highest influence on psychological behavior, while the lowest was the compulsive-anxiety factor. There was a positive correlation between the stressor scores and the psychological behavior scores (P < 0.01). The conclusion is that the pressure of nurses supporting COVID-19 ward is under moderate pressure, and the psychological behavior is moderately responded with a few nurses having psychological behavior deviation.

文摘Antibiotic re sistance genes(ARGs)in aquatic enviro nments,which seriously endanger human health and ecological safety,have become a worldwide concern due to their easy diffusion and proliferation.Wastewater treatment plants(WWTPs),which receive resistant bacteria and ARGs from a wide variety of sources(i.e.,livestock farms,hospitals,antibiotic manufactures,and households),are regarded as important emission sources of aquatic ARGs.This review presents a quantitative profile of the majority sources of ARGs in the influent of WWTPs and discusses the potential factors that affect the concentration distribution of ARGs.Specifically,a noteworthy existence of ARGs,which ranged from 1 E+05 to 1 E+11 copies/mL,was detected in livestock breeding wastewater,and household wastewater(caused by the unlimited utilization of antibiotics)was determined to be the predominant contributor of ARGs in WWTPs.We summarized the selective pressure on ARGs and determined the positive correlation of the concentration of ARGs and the existence of many containments,including antibiotics,heavy metals(Zn and Cu were frequently reported),quaternary ammonium compounds,etc.In the last section,physical,chemical,and biological treatments for the removal of ARGs and their effluent in WWTPs are discussed and prospective future studies are summarized.

文摘Climate change can intensify drought in many regions of the world and lead to more frequent drought events or altered cycles of soil water status.Therefore,it is important to enhance the tolerance to drought and thus health,vigor,and success of transplantation seedlings used in the forestry by modifying fertilization and promoting mycorrhization.Here,we sowed seeds of Japanese larch(Larix kaempferi)in 0.2-L containers with 0.5 g(low fertilization;LF)or 2 g(high fertilization;HF)of slow-release fertilizer early in the growing season.One month later,we irrigated seedlings with non-sterilized ectomycorrhizal inoculum(ECM)or sterilized solution(non-ECM),and after about 2 months,plants were either kept well watered(WW;500 mL water/plant/week)or subjected to drought(DR;50 mL water per plant/week)until the end of the growing season.HF largely stimulated plant growth and above-and belowground biomass production,eff ects that are of practical signifi cance,but caused a small decrease in stomatal conductance(Gs 390)and transpiration rate(E 390),which in practice is insignifi cant.ECM treatment resulted in moderate inhibition of seedling growth and biomass and largely canceled out the enhancement of biomass and foliar K content by HF.DR caused a large decrease in CO 2 assimilation,and enhanced stomatal closure and induced senescence.DR also largely depleted foliar Mg and enriched foliar K.Although DR caused a large decrease in foliar P content in LF,it moderately increased P in HF.Likewise,DR increased foliar K in HF but not in LF,and decreased foliar P in ECM plants but not in non-ECM plants.Conversely,ECM plants exhibited a large enrichment in foliar P under WW and had a lower water potential under DR when grown in LF.These results indicate that the drought tolerance and health and vigor of Japanese larch seedlings can be modifi ed by soil fertility and soil microorganisms.This study provides a basis for new multifactorial research programs aimed at producing seedlings of superior quality for forestation under climate change.

文摘Posttraumatic stress disorder(PTSD) is a common anxiety disorder characterised by its persistence of symptoms after a traumatic experience. Although some patients can be cured, many do not benefit enough from the psychological therapies or medication strategies used. Many researchers use animal models to learn more about the disorder and several models are available. The most-used physical stressor models are single-prolonged stress, restraint stress, foot shock, stress-enhanced fear learning, and underwater trauma. Common social stressors are housing instability, social instability, earlylife stress, and social defeat. Psychological models are not as diverse and rely on controlled exposure to the test animal's natural predator. While validation of these models has been resolved with replicated symptoms using analogous stressors, translating new findings to human patients remains essential for their impact on the field. Choosing a model to experiment with can be challenging; this overview of what is possible with individual models may aid in making a decision.

文摘Objective: The aim of this study was to reduce or eliminate the stressors to enhance nursing students' clinical learning experience through implementation of an iterative approach that developed a personalised response to student stress.Methods: A prospective cohort research design was applied to collect data from a sample of undergraduate nursing students across the four study years.An iterative approach was employed to improve students' learning experience and the Stressors in Nursing Students Scale-Chinese Version (SINS-CN) was used to measure student stress.Key problems encountered by students were identified,refined and the responding solutions were worked out and implemented among this group of students through their first year to fourth year.Results: The overall SINS-CN mean score (2.17-2.82) of students was declined to a moderate level.Conclusions: Having implemented iterative approach to address factors that led to stressful environments encountered by the nursing students,the overall stress score and each sub-dimension score decreased significantly.Therefore,it is recommended that this approach could be adopted by other colleagues in the nursing arena around the world.
文摘Objective:To evaluate the effects of low level ultraviolet (UV) radiation on sperm chromatin structure.Methods:The target study was divided into three groups: (i) males with proven fertility (n=40 ) was taken as GroupⅠ (control);(ii) Oligoasthenozoospermic (OAT) cases as GroupⅡ (n=36);(iii) males with unexplained infertility (MUI) cases (n=42) as GroupⅢ. Specific techniques were used to study the impact of UV radiation (Pre and Post UV exposure) on the sperm nuclear DNA viz. Aniline blue staining was for detection of immature chromatin. Chromomycin A3 fluorescence staining was used to determine protamine-DNA dissociation by intense fluorescence of protamine deficient sperm cells and neutral comet assay was for evaluation of DNA fragmentation. Statistical analysis was carried out using Student'st-test (GraphPad Prism Version-6). Level of significance was considered atP<0.05.Results: The data revealed that spermatozoa of OAT and MUI cases when exposed to UV-radiation showed higher percentage of immature sperm compared with normal fertile individuals. Higher percentage of Chromomycin A3 fluorescence in OAT and MUI cases revealed impaired DNA-protamine binding with subsequent DNA fragmentation after exposure to UV.Conclusions:In the present study, sperm chromatin is at higher risk of DNA fragmentation in the infertile (OAT and MUI) cases due to UV irradiation (254 nm). Hence, short duration UV exposure is detrimental to sperm DNA which could affect ensuing generations.
文摘Understanding how ecological differences and anthropogenic disturbances synergistically drive population dynamics decline is critical for optimal management strategy definition. Main anthropogenic disturbances such as habitat size reduction, fire and non-timber forest harvest affect demographic processes but our understanding of their interaction effects in contrasted ecological conditions is limited. We investigated the interaction effects of fruit harvest, fire, gallery forest size and distance to streambed on density, recruitment, survival and growth of Pentadesma butyracea offspring in dry and moist ecological conditions. We randomly selected in each ecological region six P. butyracea populations. We then established in each population, 10 subplots of 100 m2 within 1 ha to assess offspring demographic performance from 2015 to 2017. Results showed that fire suppressed the positive effect of large habitat size and amplified the negative effect of increasing local aridity on offspring growth. Fire and harvest synergistically reduced growth whereas offspring growth was resilient to fire in moist ecological region. Moist ecological conditions mitigated the negative effect of harvest on growth. Harvest mitigated the surprise negative effect of large habitat size on survival. However, in large gallery size, high harvest limited clonal recruitment and growth. There was a positive interaction effect between harvest and distance to streambed on survival (High harvest, Z = 2.045, p = 0.041, Medium, Z = 2.060, p = 0.039) but a negative interaction effect on growth (High, t = -2.357, p 0.05). Clonal offspring grew faster than sexual offspring in high harvest populations. In moist region, offspring survived better in large gallery forest size. In 2017, survival and growth were lower in large gallery forest. In 2017, offspring growth was higher near the riverbed where the survival rate low. This study suggests that management strategies should consider the interaction effects of anthropogenic disturbances and climatic conditions.
