Northeastern Puerto Rico open-canopy and under-canopy temperature and moisture data on an elevational gradient
The data archive is here:https://doi.org/10.2737/RDS-2022-0051 please use this DOI when citing this dataset. This data publication contains monthly means of temperature and moisture data collected from August 2006 through September 2021 from 22 locations along an elevational gradient, from 0 to 1045 meters, in Northeastern Puerto Rico. The higher elevational data are in the Luquillo Experimental Forest (El Yunque National Forest). Five kinds of data are included: air temperature and precipitation measured in the open (not under canopy) at 20 locations, air temperature and soil temperature both measured under the canopy at all 22 locations, and soil moisture under the canopy at 4 locations. Two locations have 3 sites each, measured in different canopy types at the same location. The other 20 locations have one site each, making a total of 26 measurement sites. Data are provided as monthly averages at each site.

An Open-set Recognition and Few-Shot Learning Dataset for Audio Event Classification in Domestic Environments
<p>The problem of training a deep neural network with a small set of positive samples is known as few-shot learning (FSL). It is widely known that traditional deep learning (DL) algorithms usually show very good performance when trained with large datasets. However, in many applications, it is not possible to obtain such a high number of samples. In the image domain, typical FSL applications are those related to face recognition. In the audio domain, music fraud or speaker recognition can be clearly benefited from FSL methods. This paper deals with the application of FSL to the detection of specific and intentional acoustic events given by different types of sound alarms, such as door bells or fire alarms, using a limited number of samples. These sounds typically occur in domestic environments where many events corresponding to a wide variety of sound classes take place. Therefore, the detection of such alarms in a practical scenario can be considered an open-set recognition (OSR) problem. To address the lack of a dedicated public dataset for audio FSL, researchers usually make modifications on other available datasets. This paper is aimed at providing the audio recognition community with a carefully annotated dataset for FSL and OSR comprised of 1360 clips from 34 classes divided into pattern sounds and unwanted sounds. To facilitate and promote research in this area, results with two baseline systems (one trained from scratch and another based on transfer learning), are presented.</p> <p> </p>
Enterprise-Driven Open Source Software
<p>We present a dataset of open source software developed mainly by enterprises rather than volunteers. This can be used to address known generalizability concerns, and, also, to perform research on open source business software development. Based on the premise that an enterprise's employees are likely to contribute to a project developed by their organization using the email account provided by it, we mine domain names associated with enterprises from open data sources as well as through white- and blacklisting, and use them through three heuristics to identify 17,264 enterprise GitHub projects. We provide these as a dataset detailing their provenance and properties. A manual evaluation of a dataset sample shows an identification accuracy of 89%. Through an exploratory data analysis we found that projects are staffed by a plurality of enterprise insiders, who appear to be pulling more than their weight, and that in a small percentage of relatively large projects development happens exclusively through enterprise insiders.</p> <p>The main dataset is provided as a 17,264 record tab-separated file named <code>enterprise_projects.txt</code> with the following 29 fields.</p> <ul> <li><strong>url</strong>: the project's GitHub URL</li> <li><strong>project_id</strong>: the project's GHTorrent identifier</li> <li><strong>sdtc</strong>: true if selected using the same domain top committers heuristic (9,016 records)</li> <li><strong>mcpc</strong>: true if selected using the multiple committers from a valid enterprise heuristic (8,314 records)</li> <li><strong>mcve</strong>: true if selected using the multiple committers from a probable company heuristic (8,015 records),</li> <li><strong>star_number</strong>: number of GitHub watchers</li> <li><strong>commit_count</strong>: number of commits</li> <li><strong>files</strong>: number of files in current main branch</li> <li><strong>lines</strong>: corresponding number of lines in text files</li> <li><strong>pull_requests</strong>: number of pull requests</li> <li><strong>github_repo_creation</strong>: timestamp of the GitHub repository creation</li> <li><strong>earliest_commit</strong>: timestamp of the earliest commit</li> <li><strong>most_recent_commit</strong>: date of the most recent commit</li> <li><strong>committer_count</strong>: number of different committers</li> <li><strong>author_count</strong>: number of different authors</li> <li><strong>dominant_domain</strong>: the projects dominant email domain</li> <li><strong>dominant_domain_committer_commits</strong>: number of commits made by committers whose email matches the project's dominant domain</li> <li><strong>dominant_domain_author_commits</strong>: corresponding number for commit authors</li> <li><strong>dominant_domain_committers</strong>: number of committers whose email matches the project's dominant domain</li> <li><strong>dominant_domain_authors</strong>: corresponding number for commit authors</li> <li><strong>cik</strong>: SEC's EDGAR "central index key"</li> <li><strong>fg500</strong>: true if this is a Fortune Global 500 company (2,233 records)</li> <li><strong>sec10k</strong>: true if the company files SEC 10-K forms (4,180 records)</li> <li><strong>sec20f</strong>: true if the company files SEC 20-F forms (429 records)</li> <li><strong>project_name</strong>: GitHub project name</li> <li><strong>owner_login</strong>: GitHub project's owner login</li> <li><strong>company_name</strong>: company name as derived from the SEC and Fortune 500 data</li> <li><strong>owner_company</strong>: GitHub project's owner company name</li> <li><strong>license</strong>: SPDX license identifier</li> </ul> <p>The file <code>cohost_project_details.txt</code> provides the full set of 311,223 cohort projects that are not part of the enterprise data set, but have comparable quality attributes.</p> <ul> <li><strong>url</strong>: the project's GitHub URL</li> <li><strong>project_id</strong>: the project's GHTorrent identifier</li> <li><strong>stars</strong>: number of GitHub watchers</li> <li><strong>commit_count</strong>: number of commits</li> </ul>
Yearly pageviews of English Wikipedia articles with potential links to green open access scholarly articles
<p>Number of visits in 2019 for a sample of 23462 English Wikipedia articles which contain references to academic sources which have a green open access copy available but not yet used. The consultation statistics were retrieved from the Wikimedia pageviews API using the Python client (script also included). The sample was selected among articles which in April 2020 had at least one citation of an academic paper (using the "cite journal" template) for which OAbot (through Unpaywall data) had found a green open access URL to add (gratis open access, not necessarily libre open access). Data shows that the top 1 % most visited articles received 30 % of the visits: over 500 million in the year, corresponding to 1 million potential citation link clicks to distribute across all references assuming a 0.2 % click-through rate per Piccardi et al. (2020).</p>

Dynamics of SARS-CoV-2 spike protein in open and closed states and identification of key structural perturbations upon mutations
<p>The SARS-Cov-2 spike protein resides on the exterior surface of the coronavirus, and therefore, acts as the first point of contact that mediates cell attachment and fusion. During this process, it undergoes dramatic conformational changes upon host receptor binding. We are leveraging high-performance computing to identify these structural perturbations in wildtype and mutant spike protein models. The files contain structures from molecular dynamics simulations of closed SARS-Cov-2 spike protein embedded in POPC membrane.</p>

Massive Open Online Courses(MOOCs) and why they fail. A case of HarvardX
<p>Massive open online courses (MOOCs) are free online courses open for everyone to enroll. MOOCs are attractive because they attempt to level the playing field and provide opportunities for students from all walks of life and from different countries to study "together" at the comfort of their own homes and this is facilitated by leading professors from renowned universities at little to no cost. They are sold as an on-demand online education to accommodate conflicting family and work responsibilities which offer students the flexibility to study and do life. Schools like University of Maryland University College were among the first universities to accept MOOCs for credit, since then more institutions have welcomed the idea of providing online education for free. MOOCs sadly have simply not lived up to their mission to transform the educational system around the world and once again we see how a good free initiative fails.<br> <br> Despite of the popularity of MOOCs, employers do not regard certifications from MOOCs as valid credentials neither as an alternative to traditional educational institutions, in essence, it is pretty useless, unless you already possess a degree from an accredited traditional educational institution. We will analyze the first two years of Harvard's attempt at offering open and free courses to all, we will look at its successes, failures and the way forward.</p> <p>The first two years 2012, 2013 Harvard offered only 5 courses. Out of the <strong>290,498</strong> registrations, <strong>49.2%</strong> of the students registered for Introduction to Computer Science, <strong>16.9%</strong> for Justice, <strong>13% </strong>for Health in numbers, <strong>12.2%</strong> for Human Health and Global environmental change and finally <strong>8.7%</strong> registered for the Ancient Greek Hero. When we break this down by gender, males outnumber females in overall registration by <strong>106,149</strong>. Analyzing individual course registration, males still outnumber females, we see this in all the courses listed and even more significantly in the Computer science subject.</p> <p>The goal of MOOCs is to make world class education accessible to all persons including students from developing countries. We do see however that the United States leads the pack in student enrollments (which is a developed country) instead of the targeted countries from the global south. <strong>78.8%</strong> of students who registered for the courseware were between ages <strong>16 and 34</strong>, we can be reasonably confident and say that most of the students are either millennials or generation z. <strong>68%</strong> of the students who registered for the courseware already possess either a bachelor's, master's or a doctorate degree(s).</p> <p>MOOCs have grown in number and popularity but failed to live up to its mission of democratizing education around the world. Out of the <strong>290948</strong> students who registered for the HarvardX open courseware in 2012 and 2013, only <strong>65,261</strong> completed the courseware representing <strong>22.4%</strong> of total student enrollments. Out of the <strong>65,261</strong> who completed the courseware only <strong>5728</strong> received certifications, distressingly representing <strong>2%</strong> of total student enrollments.</p> <p>Certification rate in general is disappointingly low but we want to see if this is true for all demographics in this dataset. We will analyze individual courses, student age, level of education as well as the country of origin to perhaps diagnose the problem of low completion and low certification. First, out of <strong>143,266</strong> students who registered for Introduction to Computer Science, only <strong>1%</strong> were certified. Out of <strong>49,293</strong> students who registered for Justice, <strong>4%</strong> were certified. Out of <strong>37709</strong> students who registered for Health in numbers, <strong>5%</strong> were certified. Out of the <strong>35509</strong> students who registered for Human health and global environmental change, <strong>2%</strong> were certified. Out of the <strong>25171</strong> students who registered for the Ancient Greek hero, only <strong>1%</strong> received certifications.</p> <p>Secondly, about 73% of the students who completed the courseware and received certification already have a bachelor's, master's or doctorate degree(s). This shows that students accessing the courseware regard it merely as a resource to fill in gaps to supplement skills already learnt in a four year traditional institution. Additionally about 67% of those who received certifications fall within ages 16 to 30 which is the targeted age group, the only problem is that there are simple not enough certifications for students within this age group compared to the number of enrollments. Out of the 229301 students enrollments who fall within this age group, only 3822 received certifications representing 1.67% of enrollments.</p> <p>We can agree that MOOCs began conceptually as a great idea but fails in implementation, the simple truth is that attitudes towards initiatives labelled 'free' in certain parts of the world encourage apathy. We see that in most countries from every continent except for Europe. Secondly, some students need external discipline to stay committed and complete the courseware but because the stakes are low and there is nothing to lose, most students simply do not see the reason to do so. Thirdly, a large number of those who registered for these courses as well as those who received certifications were from developed countries, failing to democratize education for those who need it the most, students from the global south.</p>
The Hearpiece database of individual transfer functions of an openly available in-the-ear earpiece for hearing device research
<p>We present a database of acoustic transfer functions of the Hearpiece, an openly available multi-microphone multi-driver in-the-ear earpiece for hearing device research. The database includes HRTFs for 87 incidence directions as well as responses of the drivers, all measured at the four microphones of the Hearpiece as well as the eardrum in the occluded and open ear. The transfer functions were measured in both ears of 25 human subjects and a KEMAR with anthropometric ears for five reinsertions of the device. We describe the measurements of the database and analyse derived acoustic parameters of the device. All regarded transfer functions are subject to differences between subjects as well as variations due to reinsertion into the same ear. Also, the results show that KEMAR measurements represent a median human ear well for all assessed transfer functions. The database is a rich basis for development, evaluation and robustness analysis of multiple hearing device algorithms and applications.</p>

Licenze Open Access: perché non c'è più bisogno di discuterne?
<p><strong>Perché non c’è più bisogno di discutere su quali siano le licenze più adeguate per fare Open Access?</strong><br> </p> <p>Per un semplice motivo: perché la Dichiarazione di Berlino del 2003 è così chiara su quell’aspetto che non ha più senso continuare a chiedersi quali siano le licenze adeguate per fare Open Access. La Dichiarazione di Berlino è il documento manifesto in cui fin dal 2003 sono cristallizzati i principi cardine dell'Open Access e che è stato riconosciuto e sottoscritto da quasi tutti gli atenei e le istituzioni di ricerca del pianeta.</p> <p>Chiunque sostiene che ci sia bisogno di ulteriore dibattito o non ha letto/compreso quel documento o ha interesse a diffondere incertezza.</p> <p>Potremmo fermarci qui e rimandare alla lettura della Dichiarazione di Berlino. Ma, per chiarire la questione in modo definitivo, vediamo puntualmente che cosa dice questo documento in merito alla gestione del diritto d'autore.</p> <p>La Dichiarazione di Berlino pone due semplici requisiti per rientrare nella definizione di Open Access. Il primo dei due requisiti è proprio dedicato alla gestione dei diritti d'autore e letteralmente recita:</p> <p>L’autore e il detentore dei diritti del contenuto devono garantire a tutti gli utilizzatori il diritto d’accesso gratuito, irrevocabile ed universale e l’autorizzazione a riprodurlo, utilizzarlo, distribuirlo, trasmetterlo e mostrarlo pubblicamente e a produrre e distribuire lavori da esso derivati, mantenendo comunque l’attribuzione della paternità intellettuale originaria.</p> <p> </p> <p><strong>Le licenze per fare Open Access</strong><br> </p> <p>Di conseguenza, usando come riferimento il set di licenze offerto da Creative Commons, le licenze coerenti con la definizione di Open Access sono:</p> <ul> <li><em>CC Zero</em> [che tecnicamente non è una licenza, ma un atto di rinuncia ai diritti]</li> <li><em>Attribution</em></li> <li><em>Attribution – Share Alike</em></li> </ul> <p>Le altre licenze (<em>Attribution – No Derivatives</em>; <em>Attribution – Non commercial</em>; <em>Attribution – Non commercial – Share Alike</em>; <em>Attribution – Non commercial – No Derivatives</em>) escono dal solco dell'Open Access perché impongono restrizioni eccessive. </p> <p> </p> <p><strong>Le principali obiezioni a questo approccio (e le relative smentite)</strong><br> </p> <p><em> 0) "Stai semplificando troppo. L'Open Access è un tema più complesso!"</em><br> Indubbiamente sto semplificando [forse perché questo è un post divulgativo e non un articolo scintifico o un manuale. Per un testo più articolato rimando al mio capitolo all'interno del libro "Fare Open Access" <a href="https://aliprandi.org/books/fare-openaccess/">disponibile liberamente qui</a>]. Ad ogni modo, le cose stanno davvero così; il requisito 1 della dichiarazione di Berlino è molto chiaro e cristallino; gli aspetti dell'Open Access che meritano ulteriore dibattito sono altri (e sono per lo più legati all'interpretazione del requisito 2).</p> <p><em> 1) Ma il sito DOAJ.org indicizza anche le riviste con licenze diverse da quelle tre...</em><br> Certo, infatti i responsabili del progetto DOAJ.org sbagliano; l'ho detto in varie occasioni e lo ribadisco. Capisco l'intento di indicizzare tutte le riviste scientifiche rilasciate con licenze open; ma se si mette tutto in un unico calderone (nel quale, pericolosamente, ci sono poi anche alcune licenze scritte dalle case editrici e non riconosciute come open da organizzazioni indipendenti) si rischia di creare confusione negli utenti. Basterebbe indicare le riviste sotto licenza CC BY e CC BY-SA con un colore diverso rispetto alle altre, o anche distinguerle con un asterisco che rimanda a una nota in cui si precisa che solo quelle sono coerenti con la definizione di Open Access.</p> <p><em> 2) Ma l’editore XY ha una sezione “open access” sul suo sito e da lì lascia scaricare i PDF di libri e articoli senza alcuna licenza…</em><br> Certo; ma quello è marketing, non è vero Open Access. Purtroppo c'è un utilizzo strumentale del termine "open access"; spesso viene artatamente e impropriamente associato al concetto di "gratuito" per cercare di attirare traffico sul proprio sito web o, anche qui, per confondere le acque e diffondere incertezza.</p>
