复杂性思维视域中的新型冠状病毒肺炎诊疗与防控

新型冠状病毒肺炎的诊疗与防控是复杂性事件。人们对新发急性传染病的复杂性认识不足。新型冠状病毒和新型冠状病毒肺炎本身具有本体论意义上的复杂性,表现为病原体本质复杂、传播途径复杂、临床症状复杂、防治手段复杂、环境条件复杂等复杂性特征。其中,无症状传播是新型冠状病毒肺炎防治复杂性的突出表现。复杂性思维是与新型冠状病毒肺炎诊疗和防控相适应的思维方式,体现在诊疗和防控的不可分离性、非线性、动态性、不确定性四个方面。“把人民群众生命安全和身体健康放在第一位”是应对新型冠状病毒肺炎诊疗与防控复杂性的指导思想。     

Ontological Security and Public (Mis)Recognition of International Crises: Uncertainty,Political Imagining,and the Self

Public narratives of unexpected international events frequently help (re)imagine uncertainty as something familiar or predictable. This process underlies social and political responses and is deeply significant in relation to identity and boundary security. I propose to read early perceptions of international crises through a reformulation of ontological security principles that find motivation for behavior in self‐identity needs. Political imagining is shown to seek continuous self‐concepts and to routinize new encounters within familiar and self‐affirming frames. This article suggests a new approach to ontological continuity: instead of an unchanging narrative, its security may rest in a continuously positive version of the self, with narratives of others balancing and securing the relationship. In the second half of the article, I draw on interviews about the “Arab Spring” to show how illusions of recognizing unexpected events and the political imagining this produces can be motivated by self‐concepts in need of security.     

挑战性-阻碍性压力源、角色超载和情绪枯竭的关系:心理弹性的调节作用

结合工作要求-资源模型和资源保护理论,构建并检验了挑战性和阻碍性压力源与情绪枯竭之间关系的调节中介模型。结果表明,角色超载在挑战性压力源、阻碍性压力源和情绪枯竭之间起部分中介作用。心理弹性较低时,挑战性压力源会对情绪枯竭产生直接正向影响,角色超载在它们中间不起中介作用;阻碍性压力源既对情绪枯竭产生直接正向影响,也对情绪枯竭产生间接正向影响。心理弹性较高时,挑战性压力源对情绪枯竭的直接影响不再显著,而是通过角色超载对情绪枯竭产生正向影响;阻碍性压力源同样通过角色超载对情绪枯竭产生影响。心理弹性高和心理弹性低的个体相比,阻碍性压力源对情绪枯竭影响的差异性并不显著。     

The association between attention control,anxiety, and depression: the indirect effects of repetitive negative thinking and mood recovery

Background and objectives: Attention control deficits and repetitive negative thinking (RNT; i.e., rumination) may be key factors in the development and persistence of depression and anxiety, although their role in symptom development remains poorly understood. This represents a gap in the literature, as interventions targeting attention control and associated RNT may enhance interventions and prevent costly relapse. The current study was designed to examine the serial indirect effects of transdiagnostic RNT and negative affect recovery following a lab-induced stressor on the association between attention control deficits and trait anxiety and depression.

Methods: Participants were N?=?583 university students who completed validated measures of RNT, anxiety, depression, and mood ratings pre- and post-stressor. Stress was induced using a modified version of the Trier Social Stress Test.

Results: Results of cross-sectional indirect effects models indicated that RNT and mood recovery explained the association between attention control deficits and trait anxiety and depression. Results from reversed models indicated that only the indirect effect of RNT was significant.

Conclusions: Findings suggest that RNT and mood recovery processes play an important role in explaining anxiety and depression symptoms. Additional work is needed to examine their role in symptom development and maintenance over time.     

Global cognitive function before,surrounding, and after ischemic stroke: the role of risk and protective factors varies with time among ischemic stroke survivors

An estimated 65% of individuals demonstrate multidomain cognitive impairment poststroke, although little is known about the varying role of cognitive risk and protective factors in preischemic, peri-ischemic, and postischemic stroke phases. Longitudinal changes in global cognitive function after ischemic stroke are not well characterized, especially in older adults over age 80. We examined global cognitive function trajectories in these three phases across a mean follow-up of 8.12 (2.30) years in 159 female stroke survivors aged 65–79 at baseline using linear mixed models with change points. In separate models controlling for demographic variables, we tested the interaction of baseline risk and protective factors with stroke phase on global cognitive function. None of the prestroke global cognitive function means or trajectories differed significantly. At the time of ischemic stroke, higher body mass index (BMI), the presence of hypertension (HTN), low optimism, and higher physical function were all associated with significantly greater mean decreases in global cognition (all p’s <.0.0001), but were not significantly different from the contrasting level (all p’s >0.05). Higher BMI, the presence of HTN, low optimism, and higher physical function were in turn protective of global cognitive decline postischemic stroke (all contrasting p values <.01). Baseline factors may play either a risk or a protective role in global cognitive function depending on the phase of ischemic stroke.     

Cooperative and Conflictual Policy Preferences: The Effect of Identity, Security, and Image of the Other

What is the connection between identity and conflict behavior? This article begins by exploring some of the theoretical currents in this area, notably social identity theory, Erikson's work on identity development, Burton's ontological needs, and image theory. The theories differ somewhat in their expectations of the effect of identity development. Two studies were conducted to investigate these differences. The first, a priming experiment, partitioned identity and its effects. The second, a group-based simulation study, measured actual development of ingroup identity and assessed its effect on conflict behavior. Results from the first study show that identity does affect conflict behavior, but only as it is mediated by levels of insecurity. Increased feelings of security correspond to more cooperative behavior. Positive and negative images of the opponent, on the other hand, did not influence conflict behavior. In the second study, higher levels of ingroup identity resulted in more conflictual behavior. As with the first study, image of the other was not significantly related to conflict behavior.     

Look before you leap: the role of negative urgency in appraisals of ambiguous and unambiguous scenarios in individuals high in generalized anxiety disorder symptoms

Negative interpretation bias, the propensity to make threatening interpretations of ambiguous information, is associated with symptoms of generalized anxiety disorder (GAD). Apart from its relationship with intolerance of uncertainty (IU), little is known about what explains the presence of this cognitive bias in GAD. One factor may be negative urgency (NU), the tendency to take rash action when distressed, which is related to GAD symptoms and to cognitive biases in nonclinical populations. The aim of the present study was to examine the relationship between NU and interpretation bias in individuals high in GAD symptoms (N = 111). IU, trait anxiety, and other forms of impulsivity were examined concurrently as competing correlates of interpretation bias. Greater NU and IU were found to be unique correlates of greater threatening interpretations of ambiguous scenarios. Greater NU was also a unique correlate of greater threatening interpretations of negative and positive scenarios. No other forms of impulsivity were uniquely related to interpretation bias. The findings suggest that greater NU may have a role in the tendency for individuals high in GAD symptoms to make threatening interpretations in response to ambiguous scenarios, overtly threatening situations, and situations without indication of threat or danger. Theoretical implications of these findings are discussed.     

Affective and cognitive attitudes,uncertainty avoidance and intention to obtain genetic testing: An extension of the Theory of Planned Behaviour

To ensure successful implementation of genetic screening and counselling according to patients best interests, the attitudes and motives of the public are important to consider. The aim of this study was to apply a theoretical framework in order to investigate which individual and disease characteristics might facilitate the uptake of genetic testing. A questionnaire using an extended version of the Theory of Planned Behaviour was developed to assess the predictive value of affective and cognitive expected outcomes, subjective norms, perceived control and uncertainty avoidance on the intention to undergo genetic testing. In addition to these individual characteristics, the predictive power of two disease characteristics was investigated by systematically varying the diseases fatality and penetrance (i.e. the probability of getting ill in case one is a mutation carrier). This resulted in four versions of the questionnaire which was mailed to a random sample of 2400 Norwegians. Results showed genetic test interest to be quite high, and to vary depending on the characteristics of the disease, with participants preferring tests for highly penetrant diseases. The most important individual predictor was uncertainty avoidance.     

Immigration, lack of control and psychological distress: findings from the Oslo Health Study

The aims of this study are to compare the level of psychological distress between Norwegian born and immigrants from countries with different income levels and culture, and to investigate the explanatory effect of socioeconomic and psychosocial factors, with special emphasis on lack of control (powerlessness and self-efficacy). A cross-sectional survey with self-administered questionnaire was conducted in 2000-2001 in a sample of 15,723 adults living in Oslo. Psychological distress was measured by a ten-item shortened version of Hopkins Symptom Checklist-25 items, whereas psychosocial variables were measured by various instruments. The results show that the level of psychological distress is significantly higher in immigrants from low- and middle-income countries than in the Norwegian born and the immigrants from high-income countries. They also report more powerlessness, more negative life events, less social support, less income and less paid work. It is concluded that negative life events, mainly related to social network, somatic health and economic situations, as well as lack of social support, are important mediators between immigration from low- and middle-income countries to Norway and psychological distress. Powerlessness also plays a role, but this is mainly because of a concept overlap between psychological distress and powerlessness.     

What It Means to (Mis)Trust: Forced Migration,Ontological (In)Security,and the Unrecognized Political Psychology of the Israeli-Lebanese Conflict

What does it mean to search for trust—the constitutive element of feeling ontologically secure—in the context of protracted conflict, trauma, and forced migration? This article addresses this key question in ontological security (OS) studies in International Relations (IR) by analyzing an unrecognized consequence of the Israeli-Lebanese conflict: a Lebanese community of forced migrants created overnight on Israeli premises due to Israel's unilateral withdrawal from South Lebanon in 2000. Relying on 60 in-depth interviews with Lebanese migrants in Israel, the article demonstrates how forced migrants engage in various OS-seeking strategies in relentless efforts to reconstitute trust. These strategies range from self-justification and securitizing identity through religious and communal practices, to a search for recognition from statist institutions and boundary-work vis-à-vis “sibling” disempowered “others” in the host state. However, the article shows how under political circumstances of protracted conflict and repeated perceived betrayal by the state, forced migrants are unable to reconstitute the routinized relations of trust on which OS is based. By exposing the particularistic, dynamic, and highly political character of the migrants' quest for trust, the article sheds new light on the political psychology of an “old” conflict and on the multiple meanings of ontological (in)security in migration.
