Emma Goldman (1869-1940) is a major figure in the history of radicalism and feminism in the United States. In a period when the expression of controversial ideas was dangerous, Goldman insisted on her right to challenge convention. She was among the most prominent advocates of labor's right to organize, reproductive rights, sexual freedom, freedom of speech, and freedom of the individual. Goldman left an intriguing body of personal papers, including correspondence and writings; and her activities generated extensive newspaper coverage, government surveillance reports, and legal papers. The documents in this teaching unit are drawn from a massive archive collected by the Emma Goldman Papers Project at the University of California (Berkeley). They are organized into five themes or topics: (1) "Immigration"; (2) "Freedom of Expression"; (3) "Women's Rights"; (4) "Anti-militarism"; and (5) "Art and Literature of Social Change." The topics can be taught in any sequence. Each of the five themes includes suggested activities that students may use to explore the broader significance of the documents and their context. A brief introduction to Emma Goldman and a timeline are provided for students. A glossary of terms appearing in the documents is included along with a selected resources section of annotations on books, media, and literature. (BT)

The documents in this curriculum unit are drawn from the massive archive collected by the Emma Goldman Papers Project at the University of California (Berkeley). They are linked to the standard social studies and humanities curriculum themes of art and literature, First Amendment rights, labor, progressive politics, and Red Scare, the rise of industrialization, immigration, women's rights, World War I, and yellow journalism. The unit uses the body of Goldman's personal papers, including correspondence and writings, as well as newspaper stories, government surveillance reports, and legal documents. As the records illustrate, Emma Goldman, a major figure in the history of American radicalism and feminism during a period when the expression of controversial ideas was itself dangerous, was among America's most prominent advocates of labor's right to organize, reproductive rights, sexual freedom, freedom of speech, and freedom of the individual. This curriculum is divided into five major topics all taught through the use of primary documents. Topics are: (1) Immigration; (2) Freedom of Expression; (3) Women's Rights; (4) Anti-Militarism; and (5) Arts and Literature of Social Change. A biographical essay on Emma Goldman is included, as well as an annotated list of six recommended films and videos and a 60-item annotated bibliography. (LBG)

BACKGROUND: In vitro studies using nucleus pulposus (NP) cells are commonly used to investigate disc cell biology and pathogenesis, or to aid in the development of new therapies. However, lab-to-lab variability jeopardizes the much-needed progress in the field. Here, an international group of spine scientists collaborated to standardize extraction and expansion techniques for NP cells to reduce variability, improve comparability between labs and improve utilization of funding and resources.METHODS: The most commonly applied methods for NP cell extraction, expansion, and re-differentiation were identified using a questionnaire to research groups worldwide. NP cell extraction methods from rat, rabbit, pig, dog, cow, and human NP tissue were experimentally assessed. Expansion and re-differentiation media and techniques were also investigated.RESULTS: Recommended protocols are provided for extraction, expansion, and re-differentiation of NP cells from common species utilized for NP cell culture.CONCLUSIONS: This international, multilab and multispecies study identified cell extraction methods for greater cell yield and fewer gene expression changes by applying species-specific pronase usage, 60-100 U/ml collagenase for shorter durations. Recommendations for NP cell expansion, passage number, and many factors driving successful cell culture in different species are also addressed to support harmonization, rigor, and cross-lab comparisons on NP cells worldwide.

The purpose of this article is to determine the impact of the two factors – layer thickness and printing speed in the adhesion of the layers in the ABS polymer. ABS control test tubes were printed and the tensile strength of each tube was measured. By means of statistical analysis, it was determined the impact of the layer thickness and the print speed on the adhesion between the layers. The research was focused on one of the most used materials in 3D printing. It can be concluded from the obtained results that the layer thickness has the greatest impact on the adhesion.

Autocratization has become the prevailing trend in recent political regime developments. Scholars are now increasingly addressing the global decline in democracy through both conceptual and empirical analyses to understand how autocratization initiates, unfolds, and can be halted. However, we contend that there is still a lack of comprehensive examinations that specifically elucidate the diverse outcomes of autocratization processes. In particular, we aim to determine the conditions under which autocratization can either lead or not lead to a regime change. Furthermore, we seek to discern the role played by actors of resistance against autocratization in influencing these outcomes. This article employs cutting-edge tools of Qualitative Comparative Analysis (QCA) to scrutinize recent episodes of autocratization that commenced in democracies or semi-democracies between 1993 and 2022. We achieve this by pairing information from existing expert surveys and expert-coded data. Our specific interest lies in explaining autocratization episodes that do not culminate in regime change, meaning they do not result in democratic regression or democratic breakdown. Departing from the existing small-N literature, we assess the significance of actor-based conditions of resistance against autocratization, dividing them into these macro-areas: (1) the checks and balances provided by institutional bodies like the judiciary and (2) the legislature; (3) the actions of opposition political parties through electoral alliances and coalitions; (4) the internal divisions within the incumbent party elite; the occurrence of civil society's (5) nonviolent or (6) violent protests; and (7) the intervention of external actors. To these conditions of resistance, we also incorporate whether a country possesses stable liberal-democratic institutions (8) and the overall duration of the autocratization episode (9). Our findings reveal five distinct configurations regarding the role of resistance actors, info:eu-repo/semantics/nonPublished

This work provides further insights into the metal adsorption by cyanobacterial biomass thereby offering a better understanding of underlying mechanisms. Moreover, it was demonstrated that cyanobacterial biomass has great potential for future applications in biosorption-based metal recovery from diluted aqueous solutions. Critical parameters for the uptake of Rare Earth Elements by the cyanobacterial biomass were optimized and the dominant chemical mechanisms for metal binding were characterized., Diese Arbeit gibt vertiefte Einblicke in die Metalladsorption durch Cyanobakterien-Biomasse und erweitert dadurch das Verständnis der zugrundeliegenden Mechanismen. Darüber hinaus wurde gezeigt, dass Biomasse von Cyanobakterien großes Potenzial für zukünftige Anwendungen in der biosorptionsbasierten Metallrückgewinnung aus verdünnten wässrigen Lösungen aufweist. Kritische Parameter für die Aufnahme von Seltenen Erden durch die Cyanobakterien-Biomasse wurden optimiert und die dominanten chemischen Mechanismen für die Metallbindung wurden charakterisiert.
