Prophesy of Present Value
<p>By applying critical perspectives of colonialism, development theory, and critical work on financial logic to the contemporary socio-economic conditions of Greater Miami, we begin excavating Miami’s transnational colonial heritage to provide insight into the stark socio-economic inequalities Miami exhibits today, and identify emerging forms of climate governance which has roots in social organization and exile since the city’s founding. This is a dance performance film accompanied by compositions of Emahoy Tsegue-Mariam through the waterways of Miami. Emahoy is a Ethiopian composer whose musical compositions speak to her experience in political exile during the colonial Italian-Ethiopian war of the 1930’s. The compositions deeply resonate an emotional landscape of exile and homelessness. Current scholarship on climate and gentrification points to an exile facing future Miami citizens is already and will in the future follow specific racialized patterns of economic violence in Miami, and therefore far from being environmental, remains political. Following the framework of sociologist Randy Martin, we observe the city, in prioritizing short-term economic growth in lieu of other long-term solutions, has confined the movement of bodies through space via financial valuation. In this way, the official city policy creates increasing risk for situated, low-income families of color who do not orient themselves to this slow-rolling disaster to experience a devastating, vulnerable future of homesickness and exile. This performance film emerges in the discrepancy between theory and lived experience: “how do we realize the present value of future risk?”. Just as financial transactions realize future market projections by discounting values to the present rate, we appropriate the same financial logic to take scientific projections and ‘realize’ the human impact into present values based on the current public policy outlook, closing the gap between scientific projections and racialized colonial histories.</p>
Flowering phenology and abundance, Gothic, CO, USA, 1973-present
<p>Prof. David Inouye has been collecting data on the abundance and timing of flowers that fall within permanent plots at the Rocky Mountain Biological Laboratory (RMBL), in Gothic, Colorado, USA, from 1973 to present. During the growing season, flowers of each species are counted approximately every other day, though in some years the start and/or end of flowering were missed, and data were not collected in 1978 and 1990. A core set of 23 2 x 2 m plots have been followed 1974-present (excluding 1978 and 1990), and additional plots have been added through the years (two in 1985, three in 1998, and two in 2004). Data are now collected in a total of 30 plots and up to 135 plant species have been recorded in the plots.</p>
Cognitive evoked potentials based on auditory presentations of a stimulus
<p>This database contains calculated evoked potentials from EEG data of subjects taking a cognitive test. For each EEG channel of each subject, the evoked potential was calculated separately for all stimulus presentations. For each subject, the corresponding folders contain the calculated evoked potentials for the EEG channels in separate files. Each potential has a duration of 3.4 seconds. A description of the EEG setup, subjects, and experimental design is provided below.</p><p>Data were recorded at 250 Hz sampling rate using the conventional monopolar method of registration with two reference points and N = 21 electrodes, located according to the "10–20" scheme. The adhesive Ag/AgCl electrodes in prewired head caps were used to detect EEG signals. Two reference electrodes, A1 and A2, were located on mastoids, while the ground electrode N was placed above the forehead. The EEG signals were filtered by a band-pass filter with cutoff points at 1.5 Hz (HP) and 35 Hz (LP) and a 50 Hz notch filter.</p><p>Children of middle school age participated as study subjects. The biomedical data were processed honoring the confidentiality and anonymity of the study respondents. Experimental work was carried out in compliance with ethical standards and approved by the local committee on research ethics at Saratov State University (Saratov, RF). Prior to the study, written consent of the parents was obtained for conducting neuropsychological experimental work, the subsequent data processing and publication of the results. The parents were present during all experiments in accordance with the requirements of the Russian Federation legislation.</p><p>The following design of experimental work was employed. All experiments were conducted in the mornings, on a typical school day. One of the classrooms was darkened with blinds. Children sat in comfortable chairs, adjusted to their heights to attain a comfortable stable position, leaning back in the chair. Their feet were flat on the floor. The total experimental work time was approximately 25 minutes for each subject.</p><p>The experiment included three short stages: background state of quiet wakefulness with eyes closed (about 3 minutes), simple cognitive test for counting sound signals (about 20 minutes), and repeated background state of quiet wakefulness with eyes closed (about 2 minutes). During the cognitive test, groups of short sounds were given: one to four per group. During listening, the subject was instructed to determine whether he perceived an even or an odd number of sounds in a single stimulus group. Depending on his assessment, the subject pressed the left or right buttons of a special remote control. Between groups of sound signals there was a silent pause lasting 5 to 11 seconds. Each child was analyzing these sound stimuli for 3 minutes, followed by a rest break lasting about 2 minutes.</p><p>The experimental work involved 4 boys 10 years of age (123,2±5,1 months). All children belonged to the health group I the Order of the Ministry of the Russian Federation Healthcare of March 13, 2019, No. 124n. They had no infectious or other acute illnesses one month prior to the experiment. Additionally, all children had no identified chronic diseases.</p>
Cognitive evoked potentials based on visual presentation of a stimulus
<p>This database contains calculated evoked potentials based on EEG data from subjects taking a cognitive test. For each EEG channel of each subject, the evoked potential was calculated separately for all stimulus presentations. For each subject, the corresponding folders in separate files contain the calculated evoked potentials for the EEG channels. Each potential has a duration of 3.4 seconds. In addition to the evoked potentials constructed from all presentations, which are located in files of the form "i_pot.dat", where i is the channel number. Potentials were calculated separately for simpler presentations, when 3 or 4 squares were presented, which are located in files of the form "i_pot_4.dat". And more complex presentations, when 7 or 8 squares were presented, which are in files of the form "i_pot_8.dat". A description of the EEG setup, subjects, and experimental design is provided below.</p><p>Test subjects volunteered to participate in the experiment. The biomedical data were processed honoring the confidentiality and anonymity of the study respondents. All procedures in studies involving human participants were conducted in accordance with the principles of the Declaration of Helsinki and approved by the Research Ethics Committee at Saratov State Medical University. Written informed consent was given by all participants. The participants were diagnosed in compliance with the diagnostic criteria of the International Classification of Headache Disorders (ICHD-3, beta version). We used the migraine questionnaire to evaluate the data on migraine attacks and disease courses. The exclusion criteria were acute headache, other neurological disorders, and intake of medicines targeting the central nervous system (including medications for migraine prophylaxis) within the preceding 24 h, as well as a Beck Depression Inventory (BDI) score >12 points. The sample comprised 24 subjects.</p><p>The study group included patients with chronic and recurrent migraine. The subjects had no other serious health problems, or drug or alcohol addictions. Patients were 27–66 years of age.</p><p>During all experiments, the multichannel EEG data were recorded using the EEG recorder Encephalan-EEGR-19/26 (Medicom MTD, Taganrog, Russian Federation). The data were recorded at a sampling rate of 500 Hz using the conventional monopolar recording technique with two reference electrodes and multiple recording electrodes (n = 31). EEG signals were obtained using special headcaps with prewired Ag/AgCl adhesive electrodes. Two reference electrodes, A1 and A2, were located on the mastoid processes, and the ground electrode (N) was placed above the forehead. EEG signals were filtered using a bandpass filter with cutoff frequencies of 0.5 Hz (high pass filter) and 30 Hz (low pass filter), and a notch filter of 50 Hz. The experiments were carried out in the early afternoon hours at a specially equipped laboratory. During monitoring, the subjects were in a comfortable reclining position in a neurophysiological chair with support for the neck and the back of the head in order to avoid the occurrence of artifacts associated with muscle tension in these areas. The neuropsychological experiment allowed for distinguishing cognitive ERPs. At the beginning and end of the experiment, passive wakefulness was recorded for 10 min each time. In between, the active part of the experiment was recorded for ~40 min. During the active part, short presentations of visual stimuli were delivered in a pseudorandom sequence. For all subjects, the order of stimulus presentation, duration of stimulus presentation, and duration of pauses between stimuli were identical. Each subject observed 350 stimuli. The stimulus was presented for 0.4–0.8 s. After its presentation, during a pause until the next stimulus, the subject saw solely a gray screen. After each stimulus presentation, 0.5 s of the EEG recording was used to build the EP; then 2–10 s were given to rest after the response to the stimulus. Each visual stimulus per se was an image with a different number of squares (3–8). The task of the subject was to estimate an even or odd number of squares and make a choice by pressing one of two buttons on the remote control.</p>

Agile in Academia Presents Finding your Flow: What's the Locus of your Focus? [Video]
<p>Workshop recorded on Friday, October 28th, 2022</p> <p> </p> <p><strong>Agile in Academia presenters: </strong></p> <p><strong>Doug Salcedo, MBA</strong>, Enterprise Agile DevOps Coach, Technology Consultant, SAFe Program Consultant SPC5, BSIT (35+ years of Project Management)</p> <p><strong>Mary Salcedo, Ph.D.,</strong> USDA Postdoctoral Fellow, Cornell University (10 years in academia)</p> <p>This video was recorded during a sponsored workshop from the Society of Integrative and Comparative Biology workshop to provide academics with professional development. </p> <p>Workshop focus:</p> <p><strong>Finding your flow: What’s the locus of your focus?</strong></p> <p>Often, we encounter periods of time where work seems stagnant. Things aren’t getting done, but deadlines are looming. How do we get ourselves out of the rut? How do you encourage your team, when things are piling up, but production is slowing?</p> <p>After the first Agile in Academia workshop in June, and follow up one-on-one consults, Doug and I saw a need for a flow workshop. We created a shorter “down to brass tacks” workshop to dive into skills and strategies. In this two hour workshop we’ll go over four topics: Defining Your Value Stream, What’s Your Backlog?, Kanban and Managing Tasks, and Standup Meetings and Review Cycles. You will come away with how to establish your own personal work flow, but also how to strategize if you are working or managing groups. Overall attendees will have a better understanding of their value stream what they themselves produce and its value, a working Kanban which will be workshopped in small breakout rooms, and management ideas on how to improve their personal or lab work flow.</p> <p> “Agile for Academics” is an online, hands-on workshop that focuses on bridging the knowledge gap on how to apply agile and related methodologies to managing academics projects and processes. “Agile” is a values and principles-based project management methodology, used widely in the technology industry to effectively manage work in a “lean” and sustainable fashion. Lean a value-driven process methodology focuses on providing the best value in the shortest sustainable lead time. Throughout the workshop we will talk about how to adopting and apply a “Lean-Agile Mindset” to your corner of Academia.</p>
Dataset related to article "Preservation of Axillary Lymph Nodes Compared with Complete Dissection in T1-2 Breast Cancer Patients Presenting One or Two Metastatic Sentinel Lymph Nodes: The SINODAR-ONE Multicenter Randomized Clinical Trial "
<p>This record contains raw data related to article “Preservation of Axillary Lymph Nodes Compared with Complete Dissection in T1-2 Breast Cancer Patients Presenting One or Two Metastatic Sentinel Lymph Nodes: The SINODAR-ONE Multicenter Randomized Clinical Trial"</p> <p>Abstract</p> <p><strong>Background: </strong> The SINODAR-ONE trial is a prospective noninferiority multicenter randomized study aimed at assessing the role of axillary lymph node dissection (ALND) in patients undergoing either breast-conserving surgery or mastectomy for T1-2 breast cancer (BC) and presenting one or two macrometastatic sentinel lymph nodes (SLNs). The endpoints were to evaluate whether SLN biopsy (SLNB) only was associated with worsening of the prognosis compared with ALND in terms of overall survival (OS) and relapse.</p> <p><strong>Methods: </strong> Patients were randomly assigned (1:1 ratio) to either removal of ≥ 10 axillary level I/II non-SLNs followed by adjuvant therapy (standard arm) or no further axillary treatment (experimental arm).</p> <p><strong>Results: </strong> The trial started in April 2015 and ceased in April 2020, involving 889 patients. Median follow-up was 34.0 months. There were eight deaths (ALND, 4; SNLB only, 4), with 5-year cumulative mortality of 5.8% and 2.1% in the standard and experimental arm, respectively (p = 0.984). There were 26 recurrences (ALND 11; SNLB only, 15), with 5-year cumulative incidence of recurrence of 6.9% and 3.3% in the standard and experimental arm, respectively (p = 0.444). Only one axillary lymph node recurrence was observed in each arm. The 5-year OS rates were 98.9% and 98.8%, in the ALND and SNLB-only arm, respectively (p = 0.936).</p> <p><strong>Conclusions: </strong> The 3-year survival and relapse rates of T1-2 BC patients with one or two macrometastatic SLNs treated with SLNB only, and adjuvant therapy, were not inferior to those of patients treated with ALND. These results do not support the use of routine ALND.</p>
