Thomas S. Kuhn's Lowell Lectures

For more information about this item, visit https://archivesspace.mit.edu/repositories/2/archival_objects/190184Before he wrote The Structure of Scientific Revolutions, Thomas Kuhn wrote The Quest for Physical Theory--a series of eight lectures that examine the nature of scientific knowledge, how it is created, and how it changes through time. Commissioned as public lectures in 1951 by Boston's Lowell Institute, The Quest for Physical Theory adopts the historical approach Kuhn would later refine in Structure. He surveys the history of physics from Aristotle to Newton, of atomism from antiquity to modern chemistry, and he examines the concepts of fields and subtle fluids as creative metaphors that guide research. In the last four lectures, he turns to logic and philosophy, psychology, and theories of language to explain the workings of "creative science" that are typically ignored by textbooks and many influential philosophers of science

Suicide assisted by right-to-die associations: a population based cohort study

Background: In Switzerland, assisted suicide is legal but there is concern that vulnerable or disadvantaged groups are more likely to die in this way than other people. We examined socio-economic factors associated with assisted suicide. Methods: We linked the suicides assisted by right-to-die associations during 2003-08 to a census-based longitudinal study of the Swiss population. We used Cox and logistic regression models to examine associations with gender, age, marital status, education, religion, type of household, urbanization, neighbourhood socio-economic position and other variables. Separate analyses were done for younger (25 to 64 years) and older (65 to 94 years) people. Results: Analyses were based on 5 004 403 Swiss residents and 1301 assisted suicides (439 in the younger and 862 in the older group). In 1093 (84.0%) assisted suicides, an underlying cause was recorded; cancer was the most common cause (508, 46.5%). In both age groups, assisted suicide was more likely in women than in men, those living alone compared with those living with others and in those with no religious affiliation compared with Protestants or Catholics. The rate was also higher in more educated people, in urban compared with rural areas and in neighbourhoods of higher socio-economic position. In older people, assisted suicide was more likely in the divorced compared with the married; in younger people, having children was associated with a lower rate. Conclusions: Assisted suicide in Switzerland was associated with female gender and situations that may indicate greater vulnerability such as living alone or being divorced, but also with higher education and higher socio-economic positio

Attitudinal variance among patients, next of kin and health care professionals towards the use of containment measures in three psychiatric hospitals in Switzerland

BACKGROUND In psychiatric treatment containment measures are used to de-escalate high-risk situations. These measures can be characterized by their immanent amount of coercion. Previous research could show that the attitudes towards different containment measures vary throughout countries. The aim of this study was to compare the attitudes towards containment measures between three study sites in Switzerland which differ in their clinic traditions and policies and their actual usage of these measures. METHODS We used the Attitude to Containment Measures Questionnaire (ACMQ) in three psychiatric hospitals in Switzerland (Zurich, Muensingen and Monthey) in patients, their next of kin (NOK) and health care professionals (HCP). Furthermore, we assessed the cultural specifics and rates of coercive measures for these three hospitals. RESULTS We found substantial differences in the usage of and the attitudes towards some containment measures between the three study sites. The study site accounted for a variance of nearly zero in as needed medication to 15% in seclusion. The differences between study sites were bigger in the HCPs' attitudes (up to 50% of the variance), compared to NOK and patients. In the latter the study site accounted for up to 6% of the variance. The usage/personal experience of containment measures in general was associated with higher agreement. CONCLUSIONS Although being situated in the same country, there are substantial differences in the rates of containment measures between the three study sites. We showed that the HCP's attitudes are more associated with the clinic traditions and policies compared to patients' and their NOKs' attitudes. One can conclude that patients' preferences depend less on clinic traditions and policies. Therefore, it is important to adapt treatment to the individual patients' attitudes. TRIAL REGISTRATION The study was reviewed and approved by the Cantonal Ethics Commission of Zurich, Switzerland (Ref.-No. EK: 2016-01526, decision on 28.09.2016) and the Cantonal Ethics Commission of Bern, Switzerland (Ref.-Nr. KEK-BE 2015-00074). This study has been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. The permission for conduction of the study was granted by the medical directors at the three study sites. The authors informed the respondents (patients, NOK, HCP) of their rights in the study in an oral presentation and/or a cover letter. They assured the participants of the confidentiality and anonymity of the data, and the voluntariness of participation. Patients were given an information sheet with the possibility to consent in the conduction of the study. Return of the completed questionnaires from HCP and NOK was constituted as confirmation of their consent. No identifying factors were collected to ensure privacy. This article does not contain any studies with animals performed by any of the authors

Comparing Attitudes to Containment Measures of Patients, Health Care Professionals and Next of Kin

Background: In clinical psychiatric practice, health care professionals (HCP) must decide in exceptional circumstances after the weighing of interests, which, if any, containment measures including coercion are to be used. Here, the risk for patients, staff, and third parties, in addition to therapeutic considerations, factor into the decision. Patients' preference and the inclusion of relatives in these decisions are important; therefore, an understanding of how patients and next of kin (NOK) experience different coercive measures is crucial for clinical decision making. The aim of this study is to compare how patients, HCP, and NOK assess commonly used coercive measures.Methods: A sample of 435 patients, 372 HCP, and 230 NOK completed the Attitudes to Containment Measures Questionnaire (ACMQ). This standardized self-rating questionnaire assessed the degree of acceptance or rejection of 11 coercive measures.Results: In general, HCPs rated the coercive measures as more acceptable than did NOK and patients. The largest discrepancy in the ratings was found in regard to the application of coercive intramuscular injection of medication (effect size: 1.0 HCP vs. patients). However, the ratings by NOK were significantly closer to the patients' ratings compared to patients and HCP. The only exception was the acceptance of treatment in a closed acute psychiatric ward, which was deemed significantly more acceptable by NOK than by patients. Also, patients who had experienced coercive measures themselves more strongly refused other measures.Conclusion: Patients most firmly rejected intramuscular injections, and the authors agree that these should only be used with reservation considering a high threshold. This knowledge about the discrepancy of the ratings should therefore be incorporated into professional training of HCP

A two-center pilot study on the effects of clinical ethics support on coercive measures in psychiatry.

BACKGROUND The use of formal coercion such as seclusion, mechanical restraint, and forced medication is one of the most challenging and complex issues in mental health care, on the clinical, the legal, and the ethical level. Clinical ethics support aims at assisting healthcare practitioners in determining the morally most justifiable course of action in these situations. However, the effectiveness of clinical ethics support has hardly been studied so far. METHODS Monthly moral case deliberation (MCD) was implemented in two acute wards of two different psychiatric hospitals in Switzerland. Frequency and intensity of coercion was measured on ward level (npatients = 405), and the Moral Attentiveness Scale, Knowledge on Coercion Scale, and Staff Attitudes towards Coercion Scale were applied on healthcare practitioner level (nHP = 46). Pre-post-comparisons were conducted using multi-level modeling where appropriate. RESULTS After implementation of MCD, formal coercion was less frequent (particularly seclusion, small effect size; 9.6 vs. 16.7%, p = .034, Cramér's V = .105) and less intense (particularly mechanical restraint, large effect size; 86.8 ± 45.3 vs. 14.5 ± 12.1 h, exact p = .019, r = -.74), and approval for coercive measures among healthcare practitioners was lower when controlling for the number of MCD sessions attended. CONCLUSIONS Clinical ethics support such as MCD may be a hitherto underutilized service for the reduction of coercion, complementing existing strategies and programs. Implementing clinical ethics support may help improve quality of care for persons suffering from severe mental illness

Suicide methods in Europe: a gender-specific analysis of countries participating in the "European Alliance Against Depression"

Objective: To identify the most frequent gener-specific suicide methods in Europe. Design: Proportions of seven predominant suicide methods utilised in 16 countries participating in the European Alliance Against Depression (EAAD)were reported in total and cross-nationally. Relative risk (RR)relating to suicide methods and gender was calculated. To group countries by pattern of suicide methods, hierarchical clustering was applied. Setting and participants: Data on suicide methods for 119 122 male and 41 338 female cases in 2000-4/5 from 16 EAAD countries, covering 52% of European population were obtained. Results: Hanging was the most prevalent suicide method among both males (54.3%) and females (35.6%). For males, hanging was followed by firearms (9.7%) and poisoning by drugs (8.6%); for females, by poisoning by drugs (24.7%)and jumping from a high place (14.5%). Only in Switzerland did hanging rank as second for males after firearms. Hanging ranked first among females in eight countries, poisoning by drugs in five and jumping from a high place in three. In all countries, males had a higher risk than females of using firearms and hanging and a lower risk of poisoning by drugs, drowning and jumping. Grouping showed that countries might be divided into five main groups among males; for females, grouping did not yield clear results. Conclusions: Research on suicide methods could lead to the development of gender-specific intervention strategies. Nevertheless, other approaches, such as better identification and treatment of mental disorders and the improvement of toxicological aid should be put in place

Reasons for Living and Dying in Suicide Attempters: A Two-year Prospective Study

Background: The aim of this study was to explore Reasons for Living (RFL) and Reasons for Dying (RFD) of suicide attempters and their association with current and future suicidal ideation and behavior. Method: The sample consisted of 60 patients who were admitted at a psychiatric emergency unit in Switzerland following an attempted suicide. They received treatment as usual, participated in an assessment interview and completed self-report questionnaires including written RFL and RFD responses, depressive symptoms, and suicide ideation at baseline and 6, 12 and 24 months follow-ups. Outcome measures were suicide ideation and repeated suicide attempts. Multiple imputations were used in order to address missing data. Results: The number of RFD responses was the strongest predictor for increased suicide ideation at baseline. The number of RFL responses was not associated with suicide ideation and reattempts. RFD, depressive symptoms, and baseline suicide ideation predicted subsequent suicide reattempt up to 12 months later in simple regression analyses. Mediation analyses suggested that RFD mediated the effect of depressive symptoms at baseline on suicide ideation at 12-months follow-up. Conclusion: RFL were unrelated to the mental health of study participants and did not function as protective factor against suicide risk. RFD may be an important motivational driver in the suicidal process. Clinical interventions should focus more on the reduction of RFD than on RFL in suicidal individuals

Tractography-based navigated TMS language mapping protocol

IntroductionThis study explores the feasibility of implementing a tractography-based navigated transcranial magnetic stimulation (nTMS) language mapping protocol targeting cortical terminations of the arcuate fasciculus (AF). We compared the results and distribution of errors from the new protocol to an established perisylvian nTMS protocol that stimulated without any specific targeting over the entire perisylvian cortex.MethodsSixty right-handed patients with language-eloquent brain tumors were examined in this study with one half of the cohort receiving the tractographybased protocol and the other half receiving the perisylvian protocol. Probabilistic tractography using MRtrix3 was performed for patients in the tractography-based group to identify the AF’s cortical endpoints. nTMS mappings were performed and resulting language errors were classified into five psycholinguistic groups.ResultsTractography and nTMS were successfully performed in all patients. The tractogram-based group showed a significantly higher median overall ER than the perisylvian group (3.8% vs. 2.9% p <.05). The median ER without hesitation errors in the tractogram-based group was also significantly higher than the perisylvian group (2.0% vs. 1.4%, p <.05). The ERs by error type showed no significant differences between protocols except in the no response ER, with a higher median ER in the tractogram-based group (0.4% vs. 0%, p <.05). Analysis of ERs based on the Corina cortical parcellation system showed especially high nTMS ERs over the posterior middle temporal gyrus (pMTG) in the perisylvian protocol and high ERs over the middle and ventral postcentral gyrus (vPoG), the opercular inferior frontal gyrus (opIFG) and the ventral precentral gyrus (vPrG) in the tractography-based protocol.DiscussionBy considering the white matter anatomy and performing nTMS on the cortical endpoints of the AF, the efficacy of nTMS in disrupting patients’ object naming abilities was increased. The newly introduced method showed proof of concept and resulted in AF-specific ERs and noninvasive cortical language maps, which could be applied to additional fiber bundles related to the language network in future nTMS studies
