Im südlichen Teil Brasiliens fvel in diesem Frühjahr in 10 Tagen so viel Regen wie sonst in einem ganzen Jahr. Es handelt sich um die größte klimabedingte Katastrophe im Bundesstaat Rio Grande del Sol der bereits im vergangenen Jahr von zwei großen Überschwemmungen betroffen war. Die extremen Regenfälle, die es so früher in dieser Region nicht gab, werden von Forschenden auf die globale Erhitzung und mit ihr verbundene Klimaphänomene zurückgeführt. Ausführlicher hintergrundartikel im Guardian der sich auf eine Reihe von Studien und Interviews mit Forschenden bezieht. https://www.theguardian.com/global-development/article/2024/may/10/brazil-is-reeling-from-catastrophic-floods-what-went-wrong-and-what-does-the-future-hold

European governments have thus been pushingfor reduced reliance on China’s Huawei forcritical parts of telecommunication networks inthe shift from 4G to 5G networks.
The article calls 'a 5g moment' the moment of realisation that dependencies in a tech may erode strategic position, by letting critical infrastructure to be controlled by tech firms that can be influenced by other governments. In the case of 5g it's Huawei and Chinese gov, in the case of cloud it's GAM and US gov. This is not a new notion, it is why the EU digital and data legal framework was created the past 4 yrs, so why this paper now?

1478-1518, Notebook of Leonardo da Vinci (''The Codex Arundel''). A collection of papers written in Italian by Leonardo da Vinci (b. 1452, d. 1519), in his characteristic left-handed mirror-writing (reading from right to left), including diagrams, drawings and brief texts, covering a broad range of topics in science and art, as well as personal notes. The core of the notebook is a collection of materials that Leonardo describes as ''a collection without order, drawn from many papers, which I have copied here, hoping to arrange them later each in its place according to the subjects of which they treat'' (f. 1r), a collection he began in the house of Piero di Braccio Martelli in Florence, in 1508. To this notebook has subsequently been added a number of other loose papers containing writing and diagrams produced by Leonardo throughout his career. Decoration: Numerous diagrams.

Despite the crudeness of his experimental setup 500 years ago, da Vinci, Dr. Gharib said, was able to calculate the gravitational constant to an accuracy within 10 percent of the modern value.
Nearly a hundred years before Galileo and two hundred years before Newton, in a series of diagrams and notes in the Codex Arundel, Da Viinci was able to calculate the gravitational constant to an accuracy within 10 percent of the accepted value.

The Codex Arundel, named after a British collector, the Earl of Arundel, who acquired it early in the 17th century. Da Vinci composed the collection of hundreds of papers between 1478 and 1518 — that is, between the ages of 26 and 66 — the year before his death. The papers now reside in the British Library. The collection features his famous mirror-writing as well as diagrams, drawings and texts covering a range of topics in art and science.
Da Vinci composed a collection of hundreds of papers from 1478 and 1518 which are now bound in the Codex Arundel, named for the Earl of Arundel who acquired it in the 17th century.

proposed restrictions concerning international access and transfer must be removed. Although they are aimed at non-personal data, these rules address laws (such as the US CLOUD Act and e-evidence) that will tend to involve personal data and are already covered by the GDPR.
Only the personal data are covered by GDPR (and badly adhered to if at all wrt EU-US data transfers), you can't argue that because something contains personal data that is subject to compliance the rest will 'automatically' follow suit. There are other demands being made of non-personal data in the DA than the GDPR makes of personal data, because they are different types of data. The logic here strikes me as malintentioned.
-
bring further uncertainty to companies’ international operations, which have already been severely tested by the CJEU’s Schrems II
Again, that was the point. The point is not unfettered data exchange. and there's no real uncertainty: there's no legal basis currently for EU personal data transfers to the US imo.
-
Much more stringent conditions must be set out to prevent the risk of public bodies’ misuse of data supplied to them, and to ensure the key criteria of lawfulness, necessity and proportionality under Union law are fulfilled.
Some MS, incl NL favour deleting this chapter entirely. Current proposal doesn't change anything for e.g. NSO's, except for the possibility of demanding data from companies outside your own borders (e.g. concerning flooding/river systems, supply chain disruption etc.). If this chapter is to be made impactful it should likely allow a wider set of conditions for B2G data flows, not a more stringent (the starting point after all is currently no conditions to be able to demand B2G data flows, except for e.g. NSO laws) Vgl [[Chapter 5 of the Data Act – Which should be the legal basis for B2G data sharing “exceptional need” or “public interest” 20220830140233]]

risk of ‘reverse-engineering’ for confidential business data; protections against the development of competing products and services
protection against development of competing products/services? Entrenched market forces want to stay put you mean? You don't say. They are right of course, that DA's PSD2-for-all obligations lowers the threshold for market entry to new players. Which is the point of it.
-
Proper limits to data availability must be incorporated in order to avert incentives for data misuse and unfair competition
Data being locked into products that cannot function without them is 'unfair competition' already. The DA proposes PSD2-for-everything and enables adversarial interoperability, which is encouraging fairer competition. It is an extension of the demands made of service providers in the DMA/DSA to IoT/connected product providers.
-
The proposal would impose across-the-board horizontal rules obliging data sharing, as opposed to more flexible enabling measures to spur voluntary sharing. However, there is little, largely circumstantial evidence to justify radical measures,
across-the-board / horizontal is the point of the entire digital/data legal framework the EU is drafting. Voluntary efforts have no discernable impact afaict in any industry. Moreover calling for voluntary efforts is usually meant to postpone legislative action. We've had 20+ yrs of postponement, now there's legislative action.
-
Digital Europe is a industry body, representing interests of established market players.
"Rebalancing the Data Act" raises question to which balance point the authors have in mind.

She frequently cites authors second-hand(“as quoted by”, “see,” etc.) rather than primary texts, and in some instancesthis practice results in the kinds of errors for which earlier compilations werecriticized. The most egregious of these occurs when Blair cites Ann Moss on
Guarino da Verona when making the unlikely claim that note taking begin in earnest with Francesco Sacchini in the seventeenth century rather than a hundred years earlier with Erasmus and Vives.
I almost feel like I've arrived as I noticed this error in the text myself.
Interesting that he calls her out for making a compilation error, something which is very meta with respect to this particular text.

Although humanists like Guarino da Verona(1370–1460), Desiderius Erasmus (1466–1536), and Juan Luis Vives (1492–1540)explained the principles of the commonplace book that collected phrases worthyof imitation under topical headings, they did not offer detailed practical advice
in print.33
- Moss (1996), 54–55. For Guarino’s methods, see the treatise by his son Battista in Guarino (2002); Erasmus discusses commonplacing in De copia and De ratione studii (Basel, 1512), in Erasmus (1978), 605–6, 636–38, 672; Vives does so in De tradendis disciplinis (1531), in Vives (1971), 108, 133
Double check what Erasmus has to say as it would seem that Earle Havens contradicts this in Commonplace Books (Yale University Press, 2001). Perhaps its a difference of degree? I seem to recall that he indicated that Erasmus helped to popularize commonplacing practice.

But crucially, he believes the pool at the center of the complex may have also served as a surface to observe and map the stars. The water surface would have mirrored the sky, as water does – none other than Leonardo da Vinci pointed out the attributes of inert standing water when studying the night sky. For one thing, the stars were adored by the Phoenicians, whether as gods or deceased ancestors; and the position of the constellations was of keen interest to the sailors among them for navigation purposes, Nigro points out.
Lorenzo Nigro indicates that the "kothon" of Motya in southern Sicily was a pool of Baal whose surface may have been used to observe and map the stars. He also indicates that the Phoenicians adored the stars potentially as gods or deceased ancestors. This is an example of a potentially false assumption often seen in archaeology of Western practitioners misconstruing Indigenous practices based on modern ideas of religion and culture.
I might posit that this sort of practice is more akin to that of the science of Indigenous peoples who used oral and mnemonic methods in combination with remembering their histories and ancestors.
Cross reference this with coming reading in The First Astronomers (to come) which may treat this in more depth.
Leonardo da Vinci documented the attributes of standing water for studying the night sky.
Where was this and what did it actually entail?

PTH
Paratormona: O PTH provoca, juntamente com a vitamina D e a calcitonina, a mobilização de cálcio e de fosfato no sistema esquelético e aumenta a absorção de cálcio no intestino, assim como a eliminação de fosfatos através dos rins. A constância do nível de cálcio no sangue é garantida pela ação conjunta da PTH e da calcitonina. A secreção de PTH é inibida pela elevadas concentrações de cálcio e promovida pelas baixas concentrações.

The early modern period offers yet another type of source for the firsttime: manuals of advice about how to take notes. More detailed than theprecepts of fifteenth-century humanist pedagogues like Guarino da Veronaare entire treatises on the subject produced in the Jesuit and the Germanacademic contexts of the seventeenth century.
The first manuals of advice about how to take notes began in the early modern period during the fifteenth century.

a divergence exists for any such manifold. However, it isnot unique and there are infinitely many divergences that give the same geometrical structure

The duality of the connections holds withrespect to the Riemannian metricDgin terms of the following condition:X〈Y,Z〉=〈D∇XY,Z〉+〈Y,D∇∗XZ〉(7)for all vector fieldsX,YandZ, where the brackets〈·,·〉denote the inner product with respect toDg

The databases included in EBSCOhost are well-respected and reputable. A vast majority of articles in EBSCOhost are peer-reviewed scholarly journals. ProQuest is considered a world leader in serving the information needs of researchers of all ages and abilities in libraries and institutions across the globe.
Here you can speak to how long they've been in business, how many libraries use them, as well as how well they represent the works they index.

You're not the first person to bring this up --- I know about KVL, but where do you see this in our version of EBSCO?

EBSCO needs to provide a better interface for this, though.

The ebrary e-books database through ProQuest covers a large range of subject areas,
There's no browsing option, though, and subject headings are missing. These ebooks need to be available through UK's OPAC.

About a sixth of the databases available in EBSCOhost are H.W. Wilson
This merger isn't that old. I remember the old HW Wilson databases and interface.

ProQuest also offers a basic search box at the top of the page, with options to select “Full text” and “Peer reviewed” sources, which is handy. However, using ProQuest’s databases for information seeking is probably best for browsing and less for known item searching. There is no general category for business or related topics, and the best approximation for searching for an example query like “statistics” is the “Social Sciences” category in the synopsis of the “PAIS International” database. In doing a keyword search for “statistics” on the homepage, many of the results were from the “Health & Life Sciences” category, but no connection on the general topic. The equivalent starting place for “statistics” on EBSCO would be the “Business Source Complete”, showing that EBSCO has more favorable subject specificity for known item searching.
See comment in Canvas about this.

EBSCO seems to cater more towards advanced research in characteristics that will be explored in this paper
bold claim!

A benefit of Social Services Abstracts is that it also lets you see documents with shared references
this is important

Example of a command line search for these databases: SU(abuse) AND SU(art therapy) AND TI(child)
How does this query turn out in either database?

I was able to locate the article in physical format to confirm EBSCOhost’s details and was able to assess that the particular entry I was looking for contained accurate information.
Nice test case.

which may mean there needs to be a broader search conducted
Yes, searches are not immediately transferable, and need to be translated.

Both EBSCOhost and ProQuest offer a variety of fun “extras” such as the ability to save searches and execute “cross-database” searches
How does each database handle controlled vocab when more than one database is searched?

but only EBSCOhost allows searching by series title
You can search by publication title in Proquest.

If this deep understanding is at the information seeker’s disposal, not having to set up advanced searches by applying drop down menus or clicking limiting boxes, and instead simply typing lines into a single command line search box could potentially be much more efficient.
In fact, you could create a library of these searches!
-
However, a cursory examination of the ProQuest results proved very few were actually relevant to my information needs concerning classical guitar in public schools, while six of the eight EBSCOhost results were highly useful.
Search queries do not easily translate from one database to another because the contents of the databases, albeit similar, will determine what's returned. So this is a good example of having to revise the query and trying again.
-
Of course, neither company is responsible for misinformation or quality contained within specific articles, but returned items from both databases include cross-references to authors, the subject headings applied to the content, and the full-text version of the work, when possible.
This is a good point and a good clarification about what accuracy means with respect a discussion on databases.

In considering these two particular databases, however, command line searching is only available as an explicitly framed option in IBSS.
ah! Good (see comment above)
-
Command line searching is available for both databases
Do you mean advanced searching? EBSCOhost does allow for the construction of a command line syntax, but they don't offer a convenient place to write such a query. Instead you have to enter a command line query in one of the search boxes.
-
Anthropology Plus, for instance, will produce search results for the truncated keywords “anthro*” AND “librar*” without comment. IBSS, by way of comparison, will produce a line of warning for the same search that reads: “Did you mean: anthro* AND library*?”
I'm not following. Plus, wouldn't the suggestion help users?

For instance, a search for the keywords

The subject headings are more detailed in EBSCO host than in ProQuest. In that regards, EBSCO host seems more accurate. For example, in an article on Northern Ireland,
Might it vary based on the specific database that's being used?

If I were to narrow the search only focusing on certain publications, in certain languages, during a select period of time, the results would be more closely linked with what I was looking for.
The key here would be to focus more on faceting what we want to about global warming.

Why do you think that is?

Many times with databases, it is to determine who should be published, and who is creditable enough to be published.
I think 'indexed' might be a better choice. Publishers publish.

Evaluating the accuracy of the database providers means considering the subject indexing.
I think this is a spot on observation.
-
Users can search within more than one database by check marking to select multiple titles
This raises a good question: if a thesaurus is offered in one database and not another, and a user selects both databases, is the thesaurus still offered when the user conducts a search?

EBSCOhost provides a list of its databases in an alphabetical order. ProQuest Databases arranges its databases alphabetically in two forms, by name and by subject.
What do you think about this? Does it matter?
