Additionally, suicide kills far more males than women, more so in developing regions that are characterized by economic distress due to low income. Although the number of suicide cases has been seen to increase from 2013 to date, limited studies provide information on the factors influencing the trend. Therefore, this study aimed at investigating the prevalence of suicidal ideation and factors associated with suicide in males in selected compounds of Lusaka. Methods: The study used an analytical quantitative cross- sectional study design that involved 367 men in Mtendere and Kaunda Square townships in Lusaka district, Zambia. A structured questionnaire was used to collect data from participants, which was analyzed using Statistical Package for Social Sciences (SPSS) version 26.0. The Chi-square, Fisher’s exact test and Wilcoxon rank sum tests were used to test relationships among variables at a five percent level of significance. Ethical approval and clearance was obtained from the National Health Research Authority. Results: Participants had a median age of 29 years (IQR, 27 - 32 years), 216 (58.9%) were single and 278 (75.8%) attained tertiary education. Under a quarter, 75 (20.4%) reported suicide ideations, and 97 (26.4%) reported low social support. For most participants, 347 (94.7%) experienced at least one stressful life event, and 359 (97.8%) experienced severe levels of stress. Under half, 170 (46.3%) were alcohol dependent, while 54 (14.7%) used alcohol harmfully. Suicide ideation was significantly associated with marital status (p Conclusion: Suicide ideation is relatively high among men in Mtendere and Kaunda Square townships, mainly influenced by marital status, education level, social support, stressful events alcohol abuse. Efforts must be channeled towards suicide awareness campaigns, and establishment of supportive environments in health facilities which can make it easy for men to open up about their struggles.展开更多

Despite numerous prevention efforts, a focus on the biochemistry of suicide offers new avenues for identifying those at risk and understanding the molecular mechanisms and interventions. This article reviews the biochemical mechanisms underlying suicide and the possible use of biomarkers to predict suicide ideation and attempts in humans. Information used for this review was obtained from several search engines such as Pubmed, Google Scholar, EMBASE, and AJOL. Evidence indicates that neurotransmitter imbalances, hormonal dysregulation, neuroinflammation, genetic predispositions, serotonin, dopamine, and noradrenaline imbalances, and stress hormones like cortisol contribute to suicidal behavior. Immune system dysregulation, inflammatory markers, and genetic or epigenetic modifications also play key roles in suicidal ideation and attempts. Findings suggest that understanding these biochemical factors can guide the development of early detection and targeted interventions, including pharmacotherapy and dietary adjustments. Such biochemically informed approaches could complement traditional psychological treatments, potentially reducing suicide ideation and attempts in humans.展开更多

Conceptual metaphors belong to traditional vocabulary metaphors, and ideational grammatical metaphors are pointed out by Halliday--the main representative of systemic-functional theory. This paper elaborates on the specific grammatical feature of EST （English for Science and Technology） text--＂nominalization of processes＂ to reveal the source of ideational metaphors. From the analysis of some examples, it is found that nominalization as a grammatical metaphor expresses the transference between process types, so it reveals the essence of ideational grammatical metaphors. Meanwhile, the comparison made between grammatical metaphors and vocabulary metaphors reflects the similarities between conceptual metaphors and ideational metaphors. In this way, this paper comes to the conclusion that the combination of the study methods of metaphors from both cognitive and systemic-functional perspectives is the best way to uncover the basic characteristic of human thinking.展开更多

Students were familiar with a lot of grammatical terms and were able to remember many rules. However, they often wondered why they could not use English properly and fluently although they had learned the grammatical rules quite well. This essay, taking grammar as resource for communication, suggests an approach by using ideational frameworks to the teaching and learning of grammar in a communicative context.展开更多

The present study investigated the prevalence of mental health problems and their predictors in a sample of 1048 Chinese college freshmen from Shang- hai. We used following brief screening instruments to measure symptoms of anxiety and depression, as well as self-control and suicidal ideation： the Patient Health Questionnaire （PHQ-9）, the Generalized Anxiety Disorder scale （GAD-7）, a mental health and mental health knowledge questionnaire （MK）, a mental disease-related attitude questionnaire （/VIA）, questionnaires about the knowledge of psychologi- cal services and utilities, the Mini International Neuropsychiatric Interview （MINI） Suicide module, the Self-Rated Health Measurement Scale （SFHMS）, the Self-Esteem Scale （SES）, the Simplified Coping Style Questionnaire （SCQ）, and the Perceived Stress Scale-10 （PSS-10）. Over half of the students suf- fered from at least one mental health problem. Approximately 65.55% of freshmen had depression, and 46.85% had anxiety. Minority status, low family income, and religious belief were significantly associ- ated with current mental health problems. These findings indicate that mental disorders are highly prevalent among the freshman student population. The prevalence of such mental disorders was greater than that of the general population, and the majority of students with mental health problems require treatment.展开更多

文摘Background:In contemporary society,it has been widely witnessed that a surprising number of adolescents suffer emotional and mental health problems,and such turmoil is very often carried over into adulthood with serious implications for adjustment during the post-adolescent years.The purpose of the current study is to investigate the associations of physical activity with self-esteem,depression,and suicidal ideation.In addition,this study examined whether self-esteem and depression mediate the relationship between physical activity and suicide ideation in adolescents.Methods:The study participants were 946(male:527,female:419)who attended junior high and high schools in Seoul,Korea.The self-esteem scale,leisure time physical activity scale,the self-rating depression scale,and the suicide ideation scale were used to identify adolescents’mental health and physical activity.Descriptive analysis,correlation analysis,and Structural Equation Modeling were conducted to test the study hypothesis.Results:Results indicated that physical activity was significantly correlated with depression,self-esteem,and suicide ideation.Based on each variable’s correlations,the finding revealed that physical activity was significantly associated with self-esteem,depression,and suicide ideation.In addition,depression and self-esteem had significant mediating effects on the relationship between physical activity and suicide ideation.Conclusion:The study suggests that the suicide prevention intervention should incorporate physical activity involvement with self-esteem and depression to strengthen the protective combined effect of the intervention on suicide ideation and suicide attempts.
文摘Background: Globally, it is estimated that more than 800,000 individuals die by suicide each year, making suicide one of the biggest causes of death worldwide.

文摘Suicide is a global health crisis with complex psychological, social, and biochemical dimensions. Despite numerous prevention efforts, a focus on the biochemistry of suicide offers new avenues for identifying those at risk and understanding the molecular mechanisms and interventions. This article reviews the biochemical mechanisms underlying suicide and the possible use of biomarkers to predict suicide ideation and attempts in humans. Information used for this review was obtained from several search engines such as Pubmed, Google Scholar, EMBASE, and AJOL. Evidence indicates that neurotransmitter imbalances, hormonal dysregulation, neuroinflammation, genetic predispositions, serotonin, dopamine, and noradrenaline imbalances, and stress hormones like cortisol contribute to suicidal behavior. Immune system dysregulation, inflammatory markers, and genetic or epigenetic modifications also play key roles in suicidal ideation and attempts. Findings suggest that understanding these biochemical factors can guide the development of early detection and targeted interventions, including pharmacotherapy and dietary adjustments. Such biochemically informed approaches could complement traditional psychological treatments, potentially reducing suicide ideation and attempts in humans.

文摘This study examined the effects offinancial stress,parental expectation and test anxiety on suicidal ideation in pre-medical students.For this purpose,a cross-sectional research design was used,and data were collected through a non-probability sampling technique.The sample consisted of 425 pre-medical students.Our results indicate a strong and positive association between parental expectation and suicidal ideation(β=0.272;t=3.573;p<0.000).Likewise,entrance test exam anxiety has a positive association with suicidal ideation among pre-medical students(β=0.394;t=3.933;p<0.000).Lastly,there is a significant and positive association betweenfinancial threat and suicidal ideation(β=0.185;t=2.539;p<0.011).Thefindings of the study emphasize the importance of implementing preventative measures to address the mental health issues faced by pre-medical students,with the ultimate goal of creating an environment conducive to their comprehensive development and academic success.
文摘Metaphors have different expressions in cognitive and systematic-functional linguistics, which are conceptual metaphors and ideational metaphors. Conceptual metaphors belong to traditional vocabulary metaphors, and ideational grammatical metaphors are pointed out by Halliday--the main representative of systemic-functional theory. This paper elaborates on the specific grammatical feature of EST （English for Science and Technology） text--＂nominalization of processes＂ to reveal the source of ideational metaphors. From the analysis of some examples, it is found that nominalization as a grammatical metaphor expresses the transference between process types, so it reveals the essence of ideational grammatical metaphors. Meanwhile, the comparison made between grammatical metaphors and vocabulary metaphors reflects the similarities between conceptual metaphors and ideational metaphors. In this way, this paper comes to the conclusion that the combination of the study methods of metaphors from both cognitive and systemic-functional perspectives is the best way to uncover the basic characteristic of human thinking.
文摘The SFG deals mainly with the study of language in context. Two texts on the same topic in different genres are chosen and they are analyzed from the dimensions of Field (What is the text about?),Tenor (What is the reader-writer relationship?) and Mode (What is the medium of communication,and how is the message organized?),which relate to Ideational,Interpersonal and Textual Metafuntions of language respectively.
文摘This paper analyzes the cohesion and coherence of Susan E.Rice commencement address at Stanford University in2010(Excerpt)from the perspective of systemic functional linguistics.A conclusion can be drawn that this part of the speech is highly cohesive and coherent both grammatically and textually no matter from ideational meaning,interpersonal meaning and textual meaning.
文摘The teaching and learning of grammar used to be processed at the sentence level with paying little attention to discourse and context. Students were familiar with a lot of grammatical terms and were able to remember many rules. However, they often wondered why they could not use English properly and fluently although they had learned the grammatical rules quite well. This essay, taking grammar as resource for communication, suggests an approach by using ideational frameworks to the teaching and learning of grammar in a communicative context.
文摘Summary： Anxiety, depression, and even suicidal ideation are becoming the most common mental health problems affecting Chinese college students. The present study investigated the prevalence of mental health problems and their predictors in a sample of 1048 Chinese college freshmen from Shang- hai. We used following brief screening instruments to measure symptoms of anxiety and depression, as well as self-control and suicidal ideation： the Patient Health Questionnaire （PHQ-9）, the Generalized Anxiety Disorder scale （GAD-7）, a mental health and mental health knowledge questionnaire （MK）, a mental disease-related attitude questionnaire （/VIA）, questionnaires about the knowledge of psychologi- cal services and utilities, the Mini International Neuropsychiatric Interview （MINI） Suicide module, the Self-Rated Health Measurement Scale （SFHMS）, the Self-Esteem Scale （SES）, the Simplified Coping Style Questionnaire （SCQ）, and the Perceived Stress Scale-10 （PSS-10）. Over half of the students suf- fered from at least one mental health problem. Approximately 65.55% of freshmen had depression, and 46.85% had anxiety. Minority status, low family income, and religious belief were significantly associ- ated with current mental health problems. These findings indicate that mental disorders are highly prevalent among the freshman student population. The prevalence of such mental disorders was greater than that of the general population, and the majority of students with mental health problems require treatment.
