Digital labour shortage: a new divide in library and information studies education?
This paper offers a preliminary reflection on the degree to which the concept of 'digital labour' appears in current library and information studies (LIS) education language, including in course titles, course descriptions, and course content. A basis for this paper was established from September 2010 to April 2011 through examination of a global range of online publicly accessible LIS program information. First stage analysis indicates that LIS education language appears to treat digital labour reductively; it fails to account for the labour conditions that frame the work. A tightening of the search examined evidence of critical teaching and learning of digital labour that allow for determinations of how the digital work environment relates to library labour rights and movements. This resulted in a scan of English language and translated information for a total of 121 individual LIS programs. Several trends emerged, which suggest that digital labour is generally, and most often out of necessity, inherently connected to other issues studied in LIS programs. A potential, yet unborn, paradigm in LIS education negates the basic notion of digital labour movement. Recommendations include research into the potential value of teaching and learning about the theory and practice of digital labour, a more sufficient and sophisticated approach to digital labour within LIS education in foundations courses, and a proposed set of possible advanced topics for teaching and learning in LIS education. Limitations of this topical exploration include what might be explained by the unknown factor of what is actually unseen from publicly accessible documents. To test the meaning of our first-stage work, future inquiry might involve interviews with teachers and looking into classroom communication of learners to see how the idea of digital labour is being addressed by them even if it is only in the most subtle manner
Nuclear Envelope, Nuclear Lamina, and Inherited Disease
The nuclear envelope is composed of the nuclear membranes, nuclear lamina, and nuclear pore complexes. In recent years, mutations in nuclear-envelope proteins have been shown to cause a surprisingly wide array of inherited diseases. While the mutant proteins are generally expressed in most or all differentiated somatic cells, many mutations cause fairly tissue-specific disorders. Perhaps the most dramatic case is that of mutations in A-type lamins, intermediate filament proteins associated with the inner nuclear membrane. Different mutations in the same lamin proteins have been shown to cause striated muscle diseases, partial lipodystrophy syndromes, a peripheral neuropathy, and disorders with features of severe premature aging. In this review, we summarize fundamental aspects of nuclear envelope structure and function, the inherited diseases caused by mutations in lamins and other nuclear envelope proteins, and possible pathogenic mechanisms
Injection of CO2-saturated brine in geological reservoir: a way to enhanced storage safety
Injection of free-phase supercritical CO2 into deep geological reservoirs is associated with risk of considerable return flows towards the land surface due to the buoyancy of CO2, which is lighter than the resident brine in the reservoir. Such upward movements can be avoided if CO2 is injected in the dissolved phase (CO2aq). In this work, injection of CO2-saturated brine in a subsurface carbonate reservoir was modelled. Physical and geochemical interactions of injected low-pH CO2-saturated brine with the carbonate minerals (calcite, dolomite and siderite) were investigated in the reactive transport modelling. CO2-saturated brine, being low in pH, showed high reactivity with the reservoir minerals, resulting in a significant mineral dissolution and CO2 conversion in reactions. Over the injection period of 10 yr, up to 16% of the injected CO2 was found consumed in geochemical reactions. Sorption included in the transport analysis resulted in additional quantities of CO2 mass stored. However, for the considered carbonate minerals, the consumption of injected CO2aq was found mainly in the form of ionic trapping.Peer ReviewedPostprint (author's final draft
Oscillation threshold of a clarinet model: a numerical continuation approach
This paper focuses on the oscillation threshold of single reed instruments.
Several characteristics such as blowing pressure at threshold, regime
selection, and playing frequency are known to change radically when taking into
account the reed dynamics and the flow induced by the reed motion. Previous
works have shown interesting tendencies, using analytical expressions with
simplified models. In the present study, a more elaborated physical model is
considered. The influence of several parameters, depending on the reed
properties, the design of the instrument or the control operated by the player,
are studied. Previous results on the influence of the reed resonance frequency
are confirmed. New results concerning the simultaneous influence of two model
parameters on oscillation threshold, regime selection and playing frequency are
presented and discussed. The authors use a numerical continuation approach.
Numerical continuation consists in following a given solution of a set of
equations when a parameter varies. Considering the instrument as a dynamical
system, the oscillation threshold problem is formulated as a path following of
Hopf bifurcations, generalizing the usual approach of the characteristic
equation, as used in previous works. The proposed numerical approach proves to
be useful for the study of musical instruments. It is complementary to
analytical analysis and direct time-domain or frequency-domain simulations
since it allows to derive information that is hardly reachable through
simulation, without the approximations needed for analytical approach

Funding to bridge the digital divide: U.S. philanthropic giving to digital equity causes
Almost one in two people on the planet still don't have access to the internet. 120 millionAmericans still live without broadband. As the pandemic moved many of life's essential services online, the steep human costs of this digital divide came into sharp focus.With governments and economies rapidly digitizing, achieving digital equity — a state in which all individuals have the digital access, tools, and skills they need to operate in our digitizing society — is essential for civil society to deliver programs and achieve missions. Ensuring everyone has fast, reliable, affordable internet access is fundamental to progress on the causes we care most about — from education and economic development, to health and civic participation — within the communities we most care about.With digitalization so profoundly impacting the issues funders invest in, philanthropy must build an understanding of how the digital divide impacts its work and develop strategies to tackle it. To that end, this brief seeks to understand the extent to which philanthropy has invested in digital equity. As you'll see, the results suggest that the volume of grants awarded up to 2020 falls far short of what is needed. There is a huge opportunity for philanthropy to get involved in the digital equity space and make a significant impact.
