财务困境预测通用的四种方法为判别分析、逻辑回归、神经网络和支持向量机。实证研究显示,支持向量机和神经网络模型预测的误判率较低,逻辑回归和判别分析模型预测的误判率稍高。  相似文献

以医药制造业上市公司为例,在一个特定的行业背景下,采用非配对取样方式,应用Log istic离散时间风险模型,对公司经营困境风险进行了动态评价。结果显示,股票的S igm a系数值、股权集中度、公司规模及资产负债率与经营困境风险显著相关。评价中发现,为了达到一个较好且合适的分类识别正确率,决策者必须在型Ⅰ类错误成本与型Ⅱ类错误成本之间进行权衡。此外,在行业内选取了经营困境公司与经营健康公司作为2个对照组,发现2组公司的经营困境风险动态演化过程存在明显差异,这种可视化演示方法对经营困境发生的危险时段有预测作用。  相似文献

本文选取2003-2004年度60家财务困境样本和120家非财务困境样本,分别运用单变量和多变量logistic分析检验了现金流量信息在财务困境预测中的相对信息含量和增量信息含量,研究发现:(1)在我国上市公司陷入财务困境前1年,经营性现金流量的相对信息含量仅次于资产报酬率和资产周转率,其预测效率优于其它应计制会计变量;(2)无论在财务困境前1年还是前2年,现金流量类变量在会计比率的基础上均具有显著的增量信息含量。本文的研究结果显示,从财务困境预测研究的角度看,充分挖掘现金流量信息的预测价值应成为未来此类研究的方向;从投资者角度看,现金流量表为投资者提供了决策有用的信息。  相似文献

Background

Midwives have a primary role in facilitating the first stage of perinatal mental health risk reduction through inquiring about perinatal mental health, identifying risk factors and current perinatal mental health problems, providing support or crisis intervention, referring for treatment and decreasing stigmatisation.

Aims

The aims of this study were to determine midwives’ (a) knowledge of and confidence to identify and manage perinatal mental health problems, (b) attitudes towards women who experience severe mental illness and (c) perceived learning needs.

Design

A cross-sectional survey design.

Methods

The study was conducted between September 2016 and April 2017 in seven Maternity services in the Republic of Ireland with a purposeful non-random convenience sample of midwives (n = 157). Data was anonymously collected utilising the Perinatal Mental Health Questionnaire, the Mental Illness: Clinician’s Attitudes scale and the Perinatal Mental Health Learning Needs questionnaire.

Findings

Midwives indicated high levels of knowledge (71.1%) and confidence (72%) in identifying women who experience depression and anxiety however, they reported less confidence in caring (43.9%) for women. Only 17.8% (n = 28) of midwives felt equipped to support women whilst 15.3% (n = 24) reported having access to sufficient information. Midwives desire education on the spectrum of perinatal mental health problems. The mean score for the Mental Illness: Clinician’s Attitudes scale was 36.31 (SD = 7.60), indicating positive attitudes towards women with severe mental illness.

Conclusion

Midwives require further education on perinatal mental health across cultures with a skill focus and which explores attitudes delivered in a study day format.  相似文献

Background

Information is needed on the prevalence of depression in Chinese women with medically defined complications across the perinatal period, as well as key risk factors to develop appropriate perinatal mental health services and ensure the services target those most in need.

Aim

The goal of this study was to examine whether women’s perinatal depression scores change across the perinatal period and evaluate risk factors associated with postnatal depression at 6-weeks after delivery.

Methods

A sample of 167 Chinese pregnant women with medically defined complications and an Edinburgh Postnatal Depression Scale  9 and/or a Postpartum Depression Screening Scale  60 were followed throughout early pregnancy (<28 weeks), late pregnancy (>28 weeks), 3-days and 6-weeks after delivery.

Findings

Repeated measures analysis of variance showed that there were significant differences on the Edinburgh Postnatal Depression Scale and Postpartum Depression Screening Scale scores at each time point between high-risk depressed and low-risk depressed groups. Binary logistic regression indicated a significant association between postnatal depression at 6-weeks after delivery and depression in late pregnancy and 3-days after delivery, postnatal stress events, postnatal complications, and concerns about the fetus.

Conclusions

Postnatal depression is a common condition with limited research among Chinese pregnant women with medically defined complications. Additional research is warranted to develop strategies to identify high-risk depressed pregnant women as well as effective treatment options during the perinatal period.  相似文献

Background

Women’s mental health in the perinatal period is understudied worldwide and in Arab countries especially.

Aim

This systematic review explores evidence of the association between women’s social resources for empowerment in the Arab World and their mental health in the prenatal and postnatal (≤1 year postpartum) periods.

Methods

Guided by Kabeer’s framework of empowerment, the authors applied a search string in PubMed and Web of Science databases to identify studies in countries of the Arab League (hereafter the Arab World) that address mental health and social resources for women’s empowerment in the perinatal period.

Findings

Of 1865 electronically retrieved articles, 23 met the inclusion criteria. Overall, the majority of studies found a positive association between social resources for empowerment and perinatal mental health. Seven studies explored the relationship between familial or general social support and prenatal mental health in Arab women, and found a significant positive association. Sixteen of the 18 studies of women in the postnatal period found that enabling familial, extra-familial, and/or general social support was positively associated with mental health.

Conclusion

This review demonstrates an association between social resources and perinatal mental health, but there is a dearth of research in this area. We call for additional research on Arab women in the perinatal period using context-specific but standardized tools to assess social resources and mental health. Evidence on positive mental health, resilience, and the influence of social resources can guide the improvement of prenatal and postpartum care services.  相似文献

ProblemNational guidelines recommending mental health screening in pregnancy have not been implemented well in routine maternity care. Women of refugee background are likely to have experienced traumatic events and resettlement stressors, yet are not often identified with mental health issues in the perinatal period.BackgroundGlobally, perinatal mental health conditions affect up to 20% of women. Many difficulties in accessing mental health care in pregnancy exist for women of refugee background including stigma, and cultural and language barriers. Technology can provide an efficient and effective method to overcome some of these barriers.AimTo determine if a digital perinatal mental health screening program is feasible and acceptable for women of refugee background.MethodsThis qualitative evaluation study used focus group and semi-structured telephone interviews with refugee and migrant women from four communities. Interpreters were used with women who spoke little or no English. Data were analysed using both an inductive and deductive approach to thematic analysis.FindingsUnder the three key themes: ‘Women’s experiences of perinatal mental health screening in pregnancy’; ‘Barriers and enablers to accessing ongoing mental health care’ and ‘Improvements to the program: the development of audio versions’, women found the program feasible and acceptable.DiscussionScreening using a mobile device offered women more privacy and opened up discussions with midwives on emotional health. Improvements in service coordination and access to further mental health management for women is required.ConclusionPerinatal mental health screening is an acceptable and feasible option for women of refugee background. Integrated models of care, case management, and patient navigators are options for improvements in uptake of referral and treatment services.  相似文献
