Video: Merlin's Time & Attention Talk (Improvised Rutgers Edition)

Video: Merlin Mann - "Time & Attention Talk (improvised)"

Audio (mp3): "Merlin Mann - 'Rutgers Time & Attention Talk'"

This is a talk I did at Rutgers earlier this month. I kinda like it, but for a weird reason. Something something, perfect storm of technology Ragnarok, and yadda yadda, I had to start the talk 20 minutes late with no slides. Nothing.

So, I riffed.

And, I ended up talking about a lot of the new stuff you can expect to see in the Inbox Zero book—work culture, managing expectations, the 3 deadly qualities of email, and one surprising reason email's not as much fun as Project Runway.

Some people liked it. I think. I liked it. I hope you do, too.

Here's the slides I would have shown. ;-)

Many thanks, again, to my great pal, Dr. Donald Schaffner, for bringing me in for this visit. I had a great time and met some fantastic, passionate people. Much appreciated.

 

Hey—know anybody who should hear this talk? Hmmm?

I’ll bet. Lucky you, you can hire me to deliver this or any of my other talks to the time- and attention-addled people you work with as well.

Current topics include email, meetings, social media, and future-proofing your passion.

Drop a note if you have an upcoming event where you think we two might be a good fit.

Building a Fantasy Army — Environment & Society

This article is by Toni Šušnjar.

Warfare and military are an integral part of much of ancient and medieval fantasy. This is no surprise: warfare was a key element in development of society and of history, and much of mythology is also about it. As such, it is difficult for fantasy writers and readers alike to avoid war and military matters in general. And if you are going to do something, try to do it well. Army does not spring from the ground like the spartoi of Jason.

Environment and Geography

Environmental conditions include terrain, climate and resources. All three influence how an army will fight and which weapons it will use.

Terrain can be highly varied, but I will divide it into three categories: mountainous, rolling hills and flat. Mountains and forests – and especially forested mountains – are conductive to infantry warfare. Depending on other conditions (such as society, climate etc.), this can mean either light infantry with focus on ambushes, raiding and guerilla warfare; or heavy infantry, with focus on direct confrontation. Both of these were, at different points, in evidence in Spain and Greece.

Building a Fantasy Army — Strategy & Organization

This article is by Toni Šušnjar.

Strategy and Enemies

The structure of an army will depend on the strategy, as strategy will determine the army’s role and tasks. A state which carries out expansion through outright territorial conquest will have large numbers of heavy infantry, combat engineers and artillery, and possibly some heavy cavalry as well (e.g. Roman Empire, 10th century Byzantine Empire). If conquest is done by slowly destroying an opponent’s economic and social structures through constant raiding (such as chevauchee or razzia / ghazw), then majority of the army will be light cavalry, with some heavy cavalry support (e.g. Seljuk and Ottoman Empires), and light infantry will be used if terrain is unsuitable for cavalry. If a state is defending against cavalry raids, then light cavalry will be dominant (e.g. 15th century Hungary), whereas heavy cavalry will predominate if enemy raiders are primarily infantry. If enemy armies are too powerful to face in the field, light and heavy cavalry will be used to harass the invading army and cut off its supplies and foraging. In terrain unsuitable for cavalry operations, heavy infantry will be used instead.

Raiding — as a strategy — is generally preferred against a peer opponent, especially if a state cannot have a developed logistical support system.

Building a Fantasy Army — Recruitment & Logistics

This article is by Toni Šušnjar.

Recruitment and Numbers

The most basic style of recruitment is that of a local militia – rural or urban – where a portion or all of the free men take up arms. Militiamen are usually not highly trained, but they make up for lack of training with motivation: fleeing not only carries social stigma, but is also harshly punished. As such, militias were more effective than what would be expected of “civilians in arms”. Militias almost always depended on relatively cheap and easy to use weapons, though urban militias might have access to more expensive weapons – such as hoplite panoply or crossbows. Tribal militias typically used weapons that were also used for hunting and sport. Peasant levy however was only ever used in a support and harassment role, and often had weapons modified from agricultural implements. Only urban militias could have heavy equipment. A common disadvantage of militia armies is the inability to deploy over long distances and time-frames due to soldiers having a day job; thus, focus on long-term warfare (be it conquest or defence) typically brings about the professionalization of the army. This also means that militias are best used in cases with high political fragmentation – such as city-states.

Building a Fantasy Army — Weapons & Tactics

This article is by Toni Šušnjar.

In Antiquity and early the Middle Ages, the main weapon was the spear. Only a few exceptions appeared: Roman legions, which used javelins instead, and Macedonian pike phalanx with its sarissa. In the later Middle Ages, the main weapon could be a pike or a polearm (such as polehammer, poleaxe, halberd etc.), before the pike made its return in early modernity. Ranged weapons were not used to cause casualties, but rather to inconvenience the enemies and break up their formation.

Weapons and tactics will adapt to each other, as well as to the terrain and the enemies faced – but adaptations will be done within the boundaries of the society. A society without a significant tradition of horse archery will not counter horse archers with their own, but rather with foot archers. Horse archery was important for nomadic societies, because they could not afford the casualties which resulted from the shock and attrition tactics of the settled societies.

Weapons and armour likewise have a relationship, but since armour is the more difficult to produce of the two, it is developments in armour which typically drive the adaptation of weapons, rather than the other way around.

Persuasion or manipulation? Limiting campaigning online

Persuasion or manipulation? Limiting campaigning online Expert comment NCapeling 15 February 2021

To tackle online disinformation and manipulation effectively, regulators must clarify the dividing line between legitimate and illegitimate campaign practices.

Democracy is at risk, not only from disinformation but from systemic manipulation of public debate online. Evidence shows social media drives control of narratives, polarization, and division on issues of politics and identity. We are now seeing regulators turn their attention to protecting democracy from disinformation and manipulation. But how should they distinguish between legitimate and illegitimate online information practices, between persuasive and manipulative campaigning?

Unregulated, the tactics of disinformation and manipulation have spread far and wide. They are no longer the preserve merely of disaffected individuals, hostile international actors, and authoritarian regimes. Facebook’s periodic reporting on coordinated inauthentic behaviour and Twitter’s on foreign information operations reveal that militaries, governments, and political campaigners in a wide range of countries, including parts of Europe and America, have engaged in manipulative or deceptive information campaigns.

For example, in September 2019, Twitter removed 259 accounts it says were ‘falsely boosting’ public sentiment online that it found to be operated by Spain’s conservative and Christian-democratic political party Partido Popular. In October 2020, Facebook removed accounts with around 400,000 followers linked to Rally Forge, a US marketing firm which Facebook claims was working on behalf of right-wing organisations Turning Point USA and Inclusive Conservation Group. And in December 2020, Facebook took down a network of accounts with more than 6,000 followers, targeting audiences in Francophone Africa and focusing on France’s policies there, finding it linked with individuals associated with the French military.

Public influence on a global scale

Even more revealingly, in its 2020 Global Inventory of Organized Social Media Manipulation, the Oxford Internet Institute (OII) found that in 81 countries, government agencies and/or political parties are using ‘computational propaganda’ in social media to shape public attitudes.

These 81 countries span the world and include not only authoritarian and less democratic regimes but also developed democracies such as many EU member states. OII found that countries with the largest capacity for computational propaganda – which include the UK, US, and Australia – have permanent teams devoted to shaping the online space overseas and at home.

OII categorizes computational propaganda as four types of communication strategy – the creation of disinformation or manipulated content such as doctored images and videos; the use of personal data to target specific segments of the population with disinformation or other false narratives; trolling, doxing or online harassment of political opponents, activists or journalists; and mass-reporting of content or accounts posted or run by opponents as part of gaming the platforms’ automated flagging, demotion, and take-down systems.

Doubtless some of the governments included within OII’s statistics argue their behaviour is legitimate and appropriate, either to disseminate information important to the public interest or to wrestle control of the narrative away from hostile actors. Similarly, no doubt some political campaigners removed by the platforms for alleged engagement in ‘inauthentic behaviour’ or ‘manipulation’ would defend the legitimacy of their conduct.

The fact is that clear limits of acceptable propaganda and information influence operations online do not exist. Platforms still share little information overall about what information operations they see being conducted online. Applicable legal principles such as international human rights law have not yet crystallised into clear rules. As information operations are rarely exposed to public view – with notable exceptions such as the Cambridge Analytica scandal – there is relatively little constraint in media and public scrutiny or censure.

OII’s annual reports and the platforms’ periodic reports demonstrate a continual expansion of deceptive and manipulative practices since 2016, and increasing involvement of private commercial companies in their deployment. Given the power of political influence as a driver, this absence of clear limits may result in ever more sophisticated techniques being deployed in the search for maximal influence.

Ambiguity over reasonable limits on manipulation plays into the hands of governments which regulate ostensibly in the name of combating disinformation, but actually in the interests of maintaining their own control of the narrative and in disregard of the human right to freedom of expression. Following Singapore’s 2019 prohibition of online untruths, 17 governments ranging from Bolivia to Vietnam to Hungary passed regulations during 2020 criminalising ‘fake news’ on COVID-19 while many other governments are alleged to censor opposition arguments or criticisms of official state narratives.

Clear limits are needed. Facebook itself has been calling for societal discussion about the limits of acceptable online behaviour for some time and has issued recommendations of its own.

The European Democracy Action Plan: Aiming to protect pluralism and vigour in democracy

The European Democracy Action Plan (EDAP), which complements the European Commission’s Digital Services Act and Digital Markets Act proposals, is a welcome step. It is ground-breaking in its efforts to protect the pluralism and vigour of European democracies by tackling all forms of online manipulation, while respecting human rights.

While the EDAP tackles disinformation, it also condemns two categories of online manipulation – information influence operations which EDAP describes as ‘coordinated efforts by either domestic or foreign actors to influence a target audience using a range of deceptive means’ and foreign interference, described as ‘coercive and deceptive efforts to disrupt the free formation and expression of individuals’ political will by a foreign state actor or its agents’. These categories include influence operations such as harnessing fake accounts or gaming algorithms, and the suppression of independent information sources through censorship or mass reporting.

But the categories are so broad they risk capturing disinformation practices not only of rogue actors, but also of governments and political campaigners both outside and within the EU. The European Commission plans to work towards refined definitions. Its discussions with member states and other stakeholders should start to determine which practices ought to be tackled as manipulative, and which ought to be tolerated as legitimate campaigning or public information practices.

The extent of the EDAP proposals on disinformation demonstrates the EU’s determination to tackle online manipulation. The EDAP calls for improved practical measures building on the Commission’s 2020 acceleration of effort in the face of COVID-19 disinformation. The Commission is considering how best to impose costs on perpetrators of disinformation, such as by disrupting financial incentives or even imposing sanctions for repeated offences.

Beyond the regulatory and risk management framework proposed by the Digital Services Act (DSA), the Commission says it will issue guidance for platforms and other stakeholders to strengthen their measures against disinformation, building on the existing EU Code of Practice on Disinformation and eventually leading to a strengthened Code with more robust monitoring requirements. These are elements of a broader package of measures in the EDAP to preserve democracy in Europe.

Until there are clear limits, manipulative practices will continue to develop and to spread. More actors will resort to them in order not to be outgunned by opponents. It is hoped forthcoming European discussions – involving EU member state governments, the European Parliament, civil society, academia and the online platforms – will begin to shape at least a European and maybe a global consensus on the limits of information influence, publicly condemning unacceptable practices while safeguarding freedom of expression.

Most importantly, following the example of the EDAP, the preservation of democracy and human rights – rather than the promotion of political or commercial interest – should be the lodestar for those discussions.

Molecular basis for histone H3 “K4me3-K9me3/2” methylation pattern readout by Spindlin1 [Gene Regulation]

Histone recognition by “reader” modules serves as a fundamental mechanism in epigenetic regulation. Previous studies have shown that Spindlin1 is a reader of histone H3K4me3 as well as “K4me3-R8me2a” and promotes transcription of rDNA or Wnt/TCF4 target genes. Here we show that Spindlin1 also acts as a potent reader of histone H3 “K4me3-K9me3/2” bivalent methylation pattern. Calorimetric titration revealed a binding affinity of 16 nm between Spindlin1 and H3 “K4me3-K9me3” peptide, which is one to three orders of magnitude stronger than most other histone readout events at peptide level. Structural studies revealed concurrent recognition of H3K4me3 and H3K9me3/2 by aromatic pockets 2 and 1 of Spindlin1, respectively. Epigenomic profiling studies showed that Spindlin1 colocalizes with both H3K4me3 and H3K9me3 peaks in a subset of genes enriched in biological processes of transcription and its regulation. Moreover, the distribution of Spindlin1 peaks is primarily associated with H3K4me3 but not H3K9me3, which suggests that Spindlin1 is a downstream effector of H3K4me3 generated in heterochromatic regions. Collectively, our work calls attention to an intriguing function of Spindlin1 as a potent H3 “K4me3-K9me3/2” bivalent mark reader, thereby balancing gene expression and silencing in H3K9me3/2-enriched regions.

Functional and structural characterization of allosteric activation of phospholipase Cϵ by Rap1A [Molecular Biophysics]

Phospholipase Cε (PLCε) is activated downstream of G protein–coupled receptors and receptor tyrosine kinases through direct interactions with small GTPases, including Rap1A and Ras. Although Ras has been reported to allosterically activate the lipase, it is not known whether Rap1A has the same ability or what its molecular mechanism might be. Rap1A activates PLCε in response to the stimulation of β-adrenergic receptors, translocating the complex to the perinuclear membrane. Because the C-terminal Ras association (RA2) domain of PLCε was proposed to the primary binding site for Rap1A, we first confirmed using purified proteins that the RA2 domain is indeed essential for activation by Rap1A. However, we also showed that the PLCε pleckstrin homology (PH) domain and first two EF hands (EF1/2) are required for Rap1A activation and identified hydrophobic residues on the surface of the RA2 domain that are also necessary. Small-angle X-ray scattering showed that Rap1A binding induces and stabilizes discrete conformational states in PLCε variants that can be activated by the GTPase. These data, together with the recent structure of a catalytically active fragment of PLCε, provide the first evidence that Rap1A, and by extension Ras, allosterically activate the lipase by promoting and stabilizing interactions between the RA2 domain and the PLCε core.

{alpha}2-Macroglobulin-like protein 1 can conȷugate and inhibit proteases through their hydroxyl groups, because of an enhanced reactivity of its thiol ester [Protein Structure and Folding]

Proteins in the α-macroglobulin (αM) superfamily use thiol esters to form covalent conjugation products upon their proteolytic activation. αM protease inhibitors use theirs to conjugate proteases and preferentially react with primary amines (e.g. on lysine side chains), whereas those of αM complement components C3 and C4B have an increased hydroxyl reactivity that is conveyed by a conserved histidine residue and allows conjugation to cell surface glycans. Human α2-macroglobulin–like protein 1 (A2ML1) is a monomeric protease inhibitor but has the hydroxyl reactivity–conveying histidine residue. Here, we have investigated the role of hydroxyl reactivity in a protease inhibitor by comparing recombinant WT A2ML1 and the A2ML1 H1084N mutant in which this histidine is removed. Both of A2ML1s' thiol esters were reactive toward the amine substrate glycine, but only WT A2ML1 reacted with the hydroxyl substrate glycerol, demonstrating that His-1084 increases the hydroxyl reactivity of A2ML1's thiol ester. Although both A2ML1s conjugated and inhibited thermolysin, His-1084 was required for the conjugation and inhibition of acetylated thermolysin, which lacks primary amines. Using MS, we identified an ester bond formed between a thermolysin serine residue and the A2ML1 thiol ester. These results demonstrate that a histidine-enhanced hydroxyl reactivity can contribute to protease inhibition by an αM protein. His-1084 did not improve A2ML1's protease inhibition at pH 5, indicating that A2ML1's hydroxyl reactivity is not an adaption to its acidic epidermal environment.

CDKN2A/p16INK4a suppresses hepatic fatty acid oxidation through the AMPK{alpha}2-SIRT1-PPAR{alpha} signaling pathway [Metabolism]

In addition to their well-known role in the control of cellular proliferation and cancer, cell cycle regulators are increasingly identified as important metabolic modulators. Several GWAS have identified SNPs near CDKN2A, the locus encoding for p16INK4a (p16), associated with elevated risk for cardiovascular diseases and type-2 diabetes development, two pathologies associated with impaired hepatic lipid metabolism. Although p16 was recently shown to control hepatic glucose homeostasis, it is unknown whether p16 also controls hepatic lipid metabolism. Using a combination of in vivo and in vitro approaches, we found that p16 modulates fasting-induced hepatic fatty acid oxidation (FAO) and lipid droplet accumulation. In primary hepatocytes, p16-deficiency was associated with elevated expression of genes involved in fatty acid catabolism. These transcriptional changes led to increased FAO and were associated with enhanced activation of PPARα through a mechanism requiring the catalytic AMPKα2 subunit and SIRT1, two known activators of PPARα. By contrast, p16 overexpression was associated with triglyceride accumulation and increased lipid droplet numbers in vitro, and decreased ketogenesis and hepatic mitochondrial activity in vivo. Finally, gene expression analysis of liver samples from obese patients revealed a negative correlation between CDKN2A expression and PPARA and its target genes. Our findings demonstrate that p16 represses hepatic lipid catabolism during fasting and may thus participate in the preservation of metabolic flexibility.
