Many of us look for ways to help students forge concrete connections between their academic studies and the real world. Universities encourage professors to develop community-based learning, allowing students to contribute to the community beyond their campus in a way that enhances their academic studies and enables them to create these connections. Scholars have theorized the many benefits of community-based learning, but professors have many questions about how to implement community-based learning in practice. What does a successful community-based learning assignment look like? What are the different ways to assess students’ learning experiences in community-based learning assignments? How can one build effective partnerships with community organizations? In these pages, you will find practical advice, theoretical framework, and firsthand accounts of community-engaged teaching across disciplines. Learn from professors who have designed assignments allowing students to complete community projects with refugees, prisoners, veterans, elementary school children, science museums, nursing homes, public libraries, and ESL populations. Students in an Anthropology course, for instance, conduct oral history interviews with refugees, and provide written transcriptions of the interviews that the refugees can then use as a learning tool in ESL classes. In a Science Methods class, students collaborate with an aquarium to produce meaningful exhibits that educate the public. First-year writing students work with veterans to create autobiographical films and write papers related to the project

Germline Maintenance Through the Multifaceted Activities of GLH/Vasa in

Vasa homologs are ATP-dependent DEAD-box helicases, multipotency factors, and critical components that specify and protect the germline. They regulate translation, amplify piwi-interacting RNAs (piRNAs), and act as RNA solvents; however, the limited availability of mutagenesis-derived alleles and their wide range of phenotypes have complicated their analysis. Now, with clustered regularly interspaced short palindromic repeats (CRISPR/Cas9), these limitations can be mitigated to determine why protein domains have been lost or retained throughout evolution. Here, we define the functional motifs of GLH-1/Vasa i

Neurodegenerative Disease and the NLRP3 Inflammasome.

The prevalence of neurodegenerative disease has increased significantly in recent years, and with a rapidly aging global population, this trend is expected to continue. These diseases are characterised by a progressive neuronal loss in the brain or peripheral nervous system, and generally involve protein aggregation, as well as metabolic abnormalities and immune dysregulation. Although the vast majority of neurodegeneration is idiopathic, there are many known genetic and environmental triggers. In the past decade, research exploring low-grade systemic inflammation and its impact on the development and progression of neurodegenerative disease has increased. A particular research focus has been whether systemic inflammation arises only as a secondary effect of disease or is also a cause of pathology. The inflammasomes, and more specifically the NLRP3 inflammasome, a crucial component of the innate immune system, is usually activated in response to infection or tissue damage. Dysregulation of the NLRP3 inflammasome has been implicated in the progression of several neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and prion diseases. This review aims to summarise current literature on the role of the NLRP3 inflammasome in the pathogenesis of neurodegenerative diseases, and recent work investigating NLRP3 inflammasome inhibition as a potential future therapy

Anthropology as Necessary Unlearning. Examples from Camps, Courts, Schools and Businesses

U ovom radu istražujem poteškoće do kojih dolazi u pokušajima komunikacije preko kulturnih granica. Oslanjam se na svoj terenski rad u različitim sredinama u Istočnoj i Srednjoj Europi – u izbjegličkim kampovima, sudnicama, školama i poduzećima – u kojem sam zaključila da komunikacija najbolje funkcionira kada se uspostavi povjerenje, a korak koji je potreban da bi do toga došlo je na obje strane naučiti kako odučiti duboko ukorijenjene pretpostavke. Rad započinje raspravom o rasnim i etničkim stereotipima, u kojoj se oslanjam na niz uvida iz evolucijske psihologije i kognitivne znanosti. Zatim se okrećem mitovima o pamćenju te predlažem kako primijeniti najnovija otkrića specijaliziranih istraživanja pamćenja. U drugom dijelu rada problematiziram koncept "interkulturnosti", koji često legitimizira ideologiju "sukoba civilizacija". Predlažem da za uspostavu stvarne interkulturne komunikacije moramo napustiti modele doslovnog prevođenja i umjesto toga iskoristiti recentne antropološke uvide u načine funkcioniranja jezika, društvene konstrukcije značenja i postizanja zajedničkog razumijevanja. Pritom se nastavljam na radove lingvističkih i pravnih antropologa u ovom području te članak zaključujem razmišljanjima o povezanim temama kontradominantnosti i smijeha.This paper explores the problems which arise when people attempt to communicate across cultural boundaries. I draw on my fieldwork experience in various settings in Eastern and Central Europe – camps, courts, schools and businesses – where I found that communication works best when trust is established, and that the necessary step to fulfil this condition was to learn how to unlearn deeply rooted assumptions on both sides. The paper begins with a discussion of racial and ethnic stereotypes, drawing on a range of insights from evolutionary psychology and cognitive science. I then turn to memory myths, suggesting how to apply recent findings from specialized memory research. In the second part of the paper, I challenge the concept of "intercultural", which can all too easily legitimate the "clash of civilisations" ideology. In order to establish real intercultural communication, I suggest that we must abandon models of verbatim translation and instead take advantage of recent anthropological insights into how language works, how meanings are socially constructed and how shared understandings are achieved. In all this, I build on the work of linguistic and legal anthropologists who are already contributing to this endeavour and conclude with some meditations on the related themes of counter-dominance and laughter

Building Better Neighborhoods Identity Design

The City of Muncie has diverse communities with friendly people, interesting past, and outstanding cultural amenities that make it a desired place to live, do business, and to visit. Until Spring 2019, a lot of the neighborhoods in Muncie were lacking proper visual identification. A strong visual identity was needed to elevate the image of the neighborhood as well as provide a sense of pride within the residents. In partnership with Building Better Neighborhoods and Muncie Action Plan, we worked with a core group of committee members from various Muncie Neighborhoods to develop their visual identity. Check out the other neighborhood identities at the Studio 165+ website: www.studio165plus.com/bb

UV-Vis spectroscopic characterization of nanomaterials in aqueous media

The physicochemical characterization of nanomaterials (NMs) is often an analytical challenge, due to their small size (at least one dimension in the nanoscale, i.e. 1–100 nm), dynamic nature, and diverse properties. At the same time, reliable and repeatable characterization is paramount to ensure safety and quality in the manufacturing of NM-bearing products. There are several methods available to monitor and achieve reliable measurement of nanoscale-related properties, one example of which is Ultraviolet-Visible Spectroscopy (UV-Vis). This is a well-established, simple, and inexpensive technique that provides non-invasive and fast real-time screening evaluation of NM size, concentration, and aggregation state. Such features make UV-Vis an ideal methodology to assess the proficiency testing schemes (PTS) of a validated standard operating procedure (SOP) intended to evaluate the performance and reproducibility of a characterization method. In this paper, the PTS of six partner laboratories from the H2020 project ACEnano were assessed through an interlaboratory comparison (ILC). Standard gold (Au) colloid suspensions of different sizes (ranging 5–100 nm) were characterized by UV-Vis at the different institutions to develop an implementable and robust protocol for NM size characterization

International genome-wide meta-analysis identifies new primary biliary cirrhosis risk loci and targetable pathogenic pathways.

Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10(-8)) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine-cytokine pathways, for which relevant therapies exist

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Adding 6 months of androgen deprivation therapy to postoperative radiotherapy for prostate cancer: a comparison of short-course versus no androgen deprivation therapy in the RADICALS-HD randomised controlled trial

Background Previous evidence indicates that adjuvant, short-course androgen deprivation therapy (ADT) improves metastasis-free survival when given with primary radiotherapy for intermediate-risk and high-risk localised prostate cancer. However, the value of ADT with postoperative radiotherapy after radical prostatectomy is unclear. Methods RADICALS-HD was an international randomised controlled trial to test the efficacy of ADT used in combination with postoperative radiotherapy for prostate cancer. Key eligibility criteria were indication for radiotherapy after radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to radiotherapy alone (no ADT) or radiotherapy with 6 months of ADT (short-course ADT), using monthly subcutaneous gonadotropin-releasing hormone analogue injections, daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as distant metastasis arising from prostate cancer or death from any cause. Standard survival analysis methods were used, accounting for randomisation stratification factors. The trial had 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 80% to 86% (hazard ratio [HR] 0·67). Analyses followed the intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov, NCT00541047. Findings Between Nov 22, 2007, and June 29, 2015, 1480 patients (median age 66 years [IQR 61–69]) were randomly assigned to receive no ADT (n=737) or short-course ADT (n=743) in addition to postoperative radiotherapy at 121 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 9·0 years (IQR 7·1–10·1), metastasis-free survival events were reported for 268 participants (142 in the no ADT group and 126 in the short-course ADT group; HR 0·886 [95% CI 0·688–1·140], p=0·35). 10-year metastasis-free survival was 79·2% (95% CI 75·4–82·5) in the no ADT group and 80·4% (76·6–83·6) in the short-course ADT group. Toxicity of grade 3 or higher was reported for 121 (17%) of 737 participants in the no ADT group and 100 (14%) of 743 in the short-course ADT group (p=0·15), with no treatment-related deaths. Interpretation Metastatic disease is uncommon following postoperative bed radiotherapy after radical prostatectomy. Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. These findings do not support the use of short-course ADT with postoperative radiotherapy in this patient population
