Content warnings — notices to students that class material may evoke their past traumas — have become entangled in (over)heated debates about the role of free speech on campus. Critics denounce content warnings as silencing tools intended to promote censorship, preclude discussion of difficult topics or punish professors who hold unpopular views. Supporters too often conflate content warnings with broader demands for classroom “safe space” that fail to recognize the distinct features of posttraumatic stress as a form of mental illness. In this article, I reconceptualize content warnings as a way to facilitate access to course material for students with posttraumatic stress disorder (PTSD). I then offer a set of concrete strategies for employing content warnings in political science courses. These strategies aim not only to support students struggling with trauma but also to de-escalate the controversy around content warnings by emphasizing how such warnings work to encourage engagement, access, and discussion.  相似文献

Most scholarship depicts the Honduran president, Tiburcio Carías Andino, as little more than an obedient puppet of the United States and the United Fruit Company, the classic client dictator running the archetypal “banana republic.” Using both Honduran and American sources, this article challenges the validity of Carías’ supposedly unquestioned compliance with American demands, arguing that Carías was an independent actor capable of using, manipulating, and defying the United States in pursuit of his own disparate goals.  相似文献

A sensitive analytical method was developed for quantitative analysis of delta(9)-tetrahydrocannabinol (delta(9)-THC), 11-nor-delta(9)-tetrahydrocannabinol-carboxylic acid (delta(9)-THC-COOH), cannabinol (CBN) and cannabidiol (CBD) in human hair. The identification of delta(9)-THC-COOH in hair would document Cannabis use more effectively than the detection of parent drug (delta(9)-THC) which might have come from environmental exposure. Ketamine was added to hair samples as internal standard for CBN and CBD. Ketoprofen was added to hair samples as internal standard for the other compounds. Samples were hydrolyzed with beta-glucuronidase/arylsulfatase for 2h at 40 degrees C. After cooling, samples were extracted with a liquid-liquid extraction procedure (with chloroform/isopropyl alcohol, after alkalinization, and n-hexane/ethyl acetate, after acidification), which was developed in our laboratory. The extracts were analysed before and after derivatization with pentafluoropropionic anhydride (PFPA) and pentafluoropropanol (PFPOH) using a Hewlett Packard gas chromatographer/mass spectrometer detector, in electron impact mode (GC/MS-EI). Derivatized delta(9)-THC-COOH was also analysed using a Hewlett Packard gas chromatographer/mass spectrometer detector, in negative ion chemical ionization mode (GC/MS-NCI) using methane as the reagent gas. Responses were linear ranging from 0.10 to 5.00 ng/mg hair for delta(9)-THC and CBN, 0.10-10.00 ng/mg hair for CBD, 0.01-5.00 ng/mg for delta(9)-THC-COOH (r(2)>0.99). The intra-assay precisions ranged from <0.01 to 12.40%. Extraction recoveries ranged from 80.9 to 104.0% for delta(9)-THC, 85.9-100.0% for delta(9)-THC-COOH, 76.7-95.8% for CBN and 71.0-94.0% for CBD. The analytical method was applied to 87 human hair samples, obtained from individuals who testified in court of having committed drug related crimes. Quantification of delta(9)-THC-COOH using GC/MS-NCI was found to be more convenient than GC/MS-EI. The latter may give rise to false negatives due to the detection limit.  相似文献

The Leopard (Italian: Il Gattopardo) is a novel by Prince Giuseppe Tomasi di Lampedusa that chronicles the end of the Bourbons' kingdom and the beginning of the Savoy dynasty, the first sovereigns of the new Kingdom of Italy (1861). Published posthumously in 1958, it became the top-selling novel in Italian history and it is considered one of the most important novels in modern Italian literature. In 2012 The Observer named it as one of the ‘10 best historical novels’. The purpose of this article is to refute the negative image of the Risorgimento as presented in this novel. The Leopard, with its broad resonance, has strongly contributed towards distorting the historical judgement on the foundations of the Italian nation, above all by failing to do justice to Prime Minister Cavour's courageous and judicious political strategy in the choice of the leadership class – also Sicilian – in the newly created Kingdom of Italy (1860–61).  相似文献

This paper is a case study of Eastern European immigrant women's social inclusion in Portugal through civic participation. An analysis of interviews conducted with women leaders and members of two ethnic associations provides a unique insight into their migrant pathways as highly educated women and the ways in which these women are constructing their citizenship in new contexts in Northern Portugal. These women's accounts of their immigrant experience embrace both the public realm, in using their own education and their children's as a means of integration but also spill over into ‘non-public’ familial relationships at home in contradictory ways. These include the sometimes traditional, gender-defined division of labour within the associations and at home and the new ways that they negotiate their relative autonomies to escape forms of violence and subordination that they face as women and immigrants.  相似文献
