In this introductory article, we provide a historical and philosophical framework for studying crisis discussions in psychology. We first trace the various meanings of crisis talk outside and inside of the sciences. We then turn to Kuhn’s concept of crisis, which is mainly an analyst’s category referring to severe clashes between theory and data. His view has also dominated many discussions on the status of psychology: Can it be considered a “mature” science, or are we dealing here with a pre- or multi-paradigmatic discipline? Against these Kuhnian perspectives, we point out that especially, but not only in psychology distinctive crisis declarations and debates have taken place since at least the late 19th century. In these, quite different usages of crisis talk have emerged, which can be determined by looking at (a) the content and (b) the dimensions of the declarations, as well as (c) the functions these declarations had for their authors. Thus, in psychology at least, ‘crisis’ has been a vigorous actor’s category, occasionally having actual effects on the future course of research. While such crisis declarations need not be taken at face value, they nevertheless help to break the spell of Kuhnian analyses of psychology’s history. They should inform ways in which the history and philosophy of psychology is studied further.  相似文献

The nation of the nationalists is always conceived to be in crisis. There is always an other standing between them and ‘it’. ‘It’ is often the impossible goal of a ‘totally gratifying nation’. Within a psychoanalytic framework, gratifying this nation is perceived as a fantasy, an object-cause of desire (Lacan), that is, a practical impossibility that neverthless keeps the practitioner trying to reach it. Within such a framework the other standing between the nationalists and their goal becomes a necessary subjective construction which allows the conversion of the impossibility of the nationalist fantasy into deferred possibility. The crisis presented by nationalist thought as triggered by the presence of the other is in fact a mode of reproducing the nationalists' belief in themselves and their nation. The ‘real’ crisis is when nationalists ‘lose’ their other and are forced to face the impossibility of the desired nation. Such situations can be described as states of nationalist anxiety. This paper, based on research during the civil war in Lebanon, examines certain events where the Lebanese Christian Nationalists were faced with the threat of losing their Muslim other. The paper describes the states of anxiety generated by this ‘threat’ and the nature of the strategies the Christian militias deployed to bring their state of anxiety to an end.  相似文献

The BCR-ABL1 oncogene is a tyrosine kinase that activates many signaling pathways, resulting in the induction of chronic myeloid leukemia (CML). Kinase inhibitors, such as imatinib, have been developed for the treatment of CML; however, the terminal, blast crisis phase of the disease remains a clinical challenge. Blast crisis CML is difficult to treat due to resistance to tyrosine kinase inhibitors, increased genomic instability and acquired secondary mutations. Our recent studies uncovered a role for Fyn in promoting BCR-ABL1 mediated cell growth and sensitivity to imatinib. Here we demonstrate that Fyn contributes to BCR-ABL1 induced genomic instability, a feature of blast crisis CML. Bone marrow cells and mouse embryonic fibroblasts derived from Fyn knockout mice transduced with BCR-ABL1 display slowed growth and clonogenic potential as compared to Fyn wild-type BCR-ABL1 expressing counterparts. K562 cells overexpressing constitutively active Fyn kinase were larger in size and displayed an accumulation of genomic abnormalities such as chromosomal aberrations and polyploidy. Importantly, loss of Fyn protected mouse embryonic fibroblast cells from increased number of chromosomal aberrations and fragments induced by BCR-ABL1. Together, these results reveal a novel role for Fyn in regulating events required for genomic maintenance and suggest that Fyn kinase activity plays a role in the progression of CML to blast crisis.  相似文献

BCR-ABL tyrosine kinase inhibitors, such as imatinib (Gleevec) are highly effective in treating human Philadelphia chromosome-positive (Ph+) chronic myeloid leukaemia (CML) in chronic phase but not in terminal acute phase; acquired drug resistance caused mainly by the development of BCR-ABL kinase domain mutations prevents cure of the leukaemia. In addition, imatinib is ineffective in treating Ph+ B-cell acute lymphoblastic leukaemia (B-ALL) and CML blast crisis, even in the absence of the kinase domain mutations. This type of drug resistance that is unrelated to BCR-ABL kinase domain mutations is caused by the insensitivity of leukaemic stem cells to kinase inhibitors such as imatinib and dasatinib, and by activation of a newly-identified signalling pathway involving SRC kinases that are independent of BCR-ABL kinase activity for activation. This SRC pathway is essential for leukaemic cells to survive imatinib treatment and for CML transition to lymphoid blast crisis. Apart from BCR-ABL and SRC kinases, stem cell pathways must also be targeted for curative therapy of Ph+ leukaemia.  相似文献

The recent price explosion of important agricultural commodities has lead to an international food crisis. The price rise is attributed to fundamental factors, such as the rising demand for dairy and meat products in China and the development of the bioenergy branch as well as on short-term factors such as the behaviour of speculators. Mobilising the worldwide supply can held to overcome the demand driven shortage of food this can be achieved through a proper design of the agricultural policy both in developed and developing countries.  相似文献

Background

Poor service user experiences are often reported on mental health inpatient wards. Crisis houses are an alternative, but evidence is limited. This paper investigates therapeutic alliances in acute wards and crisis houses, exploring how far stronger therapeutic alliance may underlie greater client satisfaction in crisis houses.

Methods and Findings

Mixed methods were used. In the quantitative component, 108 crisis house and 247 acute ward service users responded to measures of satisfaction, therapeutic relationships, informal peer support, recovery and negative events experienced during the admission. Linear regressions were conducted to estimate the association between service setting and measures, and to model the factors associated with satisfaction. Qualitative interviews exploring therapeutic alliances were conducted with service users and staff in each setting and analysed thematically.

Results

We found that therapeutic alliances, service user satisfaction and informal peer support were greater in crisis houses than on acute wards, whilst self-rated recovery and numbers of negative events were lower. Adjusted multivariable analyses suggest that therapeutic relationships, informal peer support and negative experiences related to staff may be important factors in accounting for greater satisfaction in crisis houses. Qualitative results suggest factors that influence therapeutic alliances include service user perceptions of basic human qualities such as kindness and empathy in staff and, at service level, the extent of loss of liberty and autonomy.

Conclusions and Implications

We found that service users experience better therapeutic relationships and higher satisfaction in crisis houses compared to acute wards, although we cannot exclude the possibility that differences in service user characteristics contribute to this. This finding provides some support for the expansion of crisis house provision. Further research is needed to investigate why acute ward service users experience a lack of compassion and humanity from ward staff and how this could be changed.  相似文献

Following the Second Lebanon War (2006), Israeli preparedness exercises were designed in reference to that crisis event. Hold annually for more than a decade, ‘Turning Point’ exercises are now accompanied by a ‘National Emergency Week’. After three years of fieldwork in the National Emergency Management Authority (NEMA) and the Turning Point administration, we came to realise that the conceptualisation of preparedness for such events has morphed. Through an analytical discussion on the concepts of crisis and emergency, we argue that a shift in orientation has occurred and crisis response gave birth to emergency management. That is, preparedness is no longer driven by historical precedent but has become a form of future-oriented emergency practice. Moreover, we argue, an emergency apparatus – a distinct technology of governance – has emerged that, although varying in form and composition, has become the means and ends of civilian-front preparedness.  相似文献

This paper aims to examine the extent to which human participants show higher resilience compared to computer agents in agent-based participatory experiments. We motivate and examine three types of resilient behaviour of farmers during a crisis or as response to competitive pressure: successful survival, loss-minimising farm exits, and path breaking respectively path creating growth strategies. Our experiments revealed that human decision makers recognised and exploited such resilient strategies in periods of crisis or under challenging circumstances in general better than myopic optimising agents, although they did not perform better on average. The reason can be seen in a substantial heterogeneity of human decision makers, for which we identified four categories: negligent gamblers, actors missing opportunities, solid farm managers and successful path breakers.  相似文献

Acute services for mental health crises are very important to service users and their supporters, and consume a substantial share of mental health resources in many countries. However, acute care is often unpopular and sometimes coercive, and the evidence on which models are best for patient experience and outcomes remains surprisingly limited, in part reflecting challenges in conducting studies with people in crisis. Evidence on best ap­proaches to initial assessment and immediate management is particularly lacking, but some innovative models involving extended assessment, brief interventions, and diversifying settings and strategies for providing support are potentially helpful. Acute wards continue to be central in the intensive treatment phase following a crisis, but new approaches need to be developed, evaluated and implemented to reducing coercion, addressing trauma, diversifying treatments and the inpatient workforce, and making decision‐making and care collaborative. Intensive home treatment services, acute day units, and community crisis services have supporting evidence in diverting some service users from hospital admission: a greater understanding of how best to implement them in a wide range of contexts and what works best for which service users would be valuable. Approaches to crisis management in the voluntary sector are more flexible and informal: such services have potential to complement and provide valuable learning for statutory sector services, especially for groups who tend to be underserved or disengaged. Such approaches often involve staff with personal experience of mental health crises, who have important potential roles in improving quality of acute care across sectors. Large gaps exist in many low‐ and middle‐income countries, fuelled by poor access to quality mental health care. Responses need to build on a foundation of existing community responses and contextually relevant evidence. The necessity of moving outside formal systems in low‐resource settings may lead to wider learning from locally embedded strategies.  相似文献

Despite the global declines in the rate of amphibians, evaluation of public understanding of the crisis has not yet been carried out. We surveyed visitors (n = 1,293) at 15 zoos in Brazil, New Zealand, and the United Kingdom, using a certainty‐based assessment method to compare visitor knowledge of the global amphibian crisis. We further analyzed zoo educational material about amphibians to explore its potential to raise awareness through amphibian‐focused environmental education. Visitors in the three countries had relatively little understanding of amphibians and the global amphibian crisis. When the degree of confidence in answering the questions (high, medium, and low) is accounted for, correct answers varied between 28% and 39%. This compared to scores of between 58% and 73% when the degree of confidence in responding was not accounted for. However, specific areas of knowledge (e.g., biology, conservation, biogeography, and conceptual ideas) varied significantly across the countries. Visitors had a weaker grasp of biogeographical and conservation issues than general amphibian biology. Zoo visitors in Brazil knew less about amphibian conservation than those in New Zealand or the United Kingdom. There was less amphibian‐focused content in educational materials in zoos in Brazil than there was in the United Kingdom. Improving information about the global amphibian crisis may increase support for future conservation actions. Outreach education is one of the most important approaches in any strategic planning for conservation of species. Amphibian‐focused environmental education at institutions such as zoos and aquaria can be a crucial intervention to support amphibian conservation worldwide.  相似文献

With new legislation and favorable case law developments, many providers of health care services are turning to binding arbitration agreements as a partial solution to the medical malpractice crisis. Existing data indicate tremendous advantages can be gained from the use of such agreements, if they are carefully drawn to comply with new law, tailored to the particular situation in which they will be used and coupled with appropriate procedures to secure the intended benefits.Arbitration is not a substitute for insurance, but if a provider has taken the calculated risk of forgoing insurance he should not be without a carefully drawn binding arbitration agreement.  相似文献

Primary cultures derived from lung and renal tissue of the newborn harvest mouse (Micromys minutus) were serially passaged in media supplemented with epidermal growth factor, hydrocortisone, transferrin, insulin, and triiodothyronine. Although these growth factor supplements eliminated the growth crisis commonly encountered during the initial stages of murine primary cultures, the original diploid cell fraction clearly underwent such a "crisis"; the truly diploid cells invariably disappeared as these cultures reached 20 to 40 population doublings. They were replaced, either gradually or precipitously, by various heteroploid cell fractions. In three of four independent cultures, these "established" cells were hypotetraploid and appeared to be derived from a small number of progenitors already present during the very early (precrisis) culture stages. In contrast to rather frequent DNA changes displayed by clones and subclones derived from the various heteroploid cell lineages, the predominant components of the established mass cultures displayed a highly constant DNA fluorescence pattern. Our results suggest that primary murine cell cultures develop heteroploid cell lineages even if the initial growth crisis is mitigated by growth factor supplements. These heteroploid cells appear to respond more efficiently to stimulation by various growth factors than the primary diploid cell population.  相似文献

Throughout the 1960s and 1970s, social psychologists diagnosed their field as suffering a state of disciplinary crisis. The crisis was a multifaceted one, but issues of methodology, social relevance, and disciplinary, philosophical, and theoretical orientation were the primary areas of concern. Given that these issues have been prominent ones throughout the history of the social and behavioral sciences, it becomes necessary to look to the immediate context of the 1970s crisis to understand how and why a disciplinary crisis came to be diagnosed. The present analysis suggests that the crisis reflected the larger crisis in American society and also drew on the language of crisis prevalent at the time. Employing this language may have offered the field a method of making sense of, reframing, and redirecting internal and external critiques of the discipline.  相似文献

Suicide is a crisis of unknown proportions in much of the developing world. The majority of research into suicide has been done in high-resource countries such as Australia, and most intervention protocols have been drawn up using Western models. There appear to be a number of differences in the aetiology, presentation and treatment options for mental health problems between high-resource and low-resource countries. This review compares suicide in a high-resource country, Australia, and low-resource country, Nepal.Many low-resource countries such as Nepal struggle to address barriers to mental health care due to limited mental health resources and issues such as stigma, workforce and mental health literacy. Issues relating to suicide prevention are raised, contrasting a low-resource country, Nepal, with a high-resource country, Australia.  相似文献

What truly happened in the terrestrial ecosystems in response to the famous Messinian salinity crisis is still the matter of extensive discussions. Did mammals record any faunal and/or a climatic or environmental fluctuation is a question that still remains open. Our objective is to investigate mammalian faunas before, during and after the crisis within different terrestrial basins surrounding the Mediterranean Sea. We therefore apply here two methods, the cenogram method and a transfer function based on murine (rodents) species richness to better understand if our proxies can record any qualitative or quantitative climatic or environmental change. The results indicate that mammal faunas do not record any particular shift in climate or environment at the scale of the whole peri-Mediterranean area. The trend is different at the regional scale of terrestrial basins as temperatures increase (Calatayud-Daroca-Teruel Basin) or decrease (Languedoc-Roussillon region) punctually occurs just after the crisis; stable conditions in different areas (e.g. Greece) contradict these trends. Biases in the fossil record or in the methodologies could produce such discrepancies.  相似文献

Women who have been injured should be examined for possible gynecological injury within 24 hours of the accident.Injuries to pregnant women do not usually cause an obstetrical crisis. When such an event does occur, there is positive evidence which relates it to the accident if there was such relationship.Metrorrhagia and menorrhagia are common sequelae of physical and psychological injury, but they are of temporary nature in cases in which there is no demonstrable pathologic change upon pelvic examination.Uterine prolapse, cystocele and rectocele are not caused by a single injury except in extremely rare instances. When vaginal vault injury has occurred as a result of a single injury, there is plentiful evidence of severe tissue damage.  相似文献

The current global economic crisis is expected to produce adverse mental health effects that may increase suicide and alcohol-related death rates in affected countries. In nations with greater social safety nets, the health impacts of the economic downturn may be less pronounced. Research indicates that the mental health impact of the economic crisis can be offset by various policy measures. This paper aims to outline how countries can safeguard and support mental health in times of economic downturn. It indicates that good mental health cannot be achieved by the health sector alone. The determinants of mental health often lie outside of the remits of the health system, and all sectors of society have to be involved in the promotion of mental health. Accessible and responsive primary care services support people at risk and can prevent mental health consequences. Any austerity measures imposed on mental health services need to be geared to support the modernization of mental health care provision. Social welfare supports and active labour market programmes aiming at helping people retain or re-gain jobs can counteract the mental health effects of the economic crisis. Family support programmes can also make a difference. Alcohol pricing and restrictions of alcohol availability reduce alcohol harms and save lives. Support to tackle unmanageable debt will also help to reduce the mental health impact of the crisis. While the current economic crisis may have a major impact on mental health and increase mortality due to suicides and alcohol-related disorders, it is also a window of opportunity to reform mental health care and promote a mentally healthy lifestyle.  相似文献

Replicability, the ability to replicate scientific findings, is a prerequisite for scientific discovery and clinical utility. Troublingly, we are in the midst of a replicability crisis. A key to replicability is that multiple measurements of the same item (e.g., experimental sample or clinical participant) under fixed experimental constraints are relatively similar to one another. Thus, statistics that quantify the relative contributions of accidental deviations—such as measurement error—as compared to systematic deviations—such as individual differences—are critical. We demonstrate that existing replicability statistics, such as intra-class correlation coefficient and fingerprinting, fail to adequately differentiate between accidental and systematic deviations in very simple settings. We therefore propose a novel statistic, discriminability, which quantifies the degree to which an individual’s samples are relatively similar to one another, without restricting the data to be univariate, Gaussian, or even Euclidean. Using this statistic, we introduce the possibility of optimizing experimental design via increasing discriminability and prove that optimizing discriminability improves performance bounds in subsequent inference tasks. In extensive simulated and real datasets (focusing on brain imaging and demonstrating on genomics), only optimizing data discriminability improves performance on all subsequent inference tasks for each dataset. We therefore suggest that designing experiments and analyses to optimize discriminability may be a crucial step in solving the replicability crisis, and more generally, mitigating accidental measurement error.  相似文献
