As a mom of 4 I have spent a significant amount of my time discussing the virtues of truth telling and the consequences of telling a lie, at this moment one of the kids is writing me an essay on using self-control to ensure her words are true.

Today is also death anniversary of P.V.Narasimha Rao, the man who liberalized the Indian economy, and opened it up. And more than anything else, provided the much needed stability for India in the turbulent 90s. One of the best PMs IMO. #PVNarasimhaRao

The man who dismantled India's Licence Raj, opened up relations with Israel, adopted a Look East Policy. P.V.Narasimha Rao took over as PM, when India was faced with multiple challenges both on political and economic front in 1991.

Assasination of Rajiv Gandhi, Economic crisis, India was facing a bleak scenario, in 1991 when PVNR became the PM. It is to PVNR's credit that when he stepped down as PM in 1996,more people in India were optimistic about their future, more confident. #PVNarasimhaRao

I was one of those who grew up during the PVNR era, experienced the initial changes he bought along. He introduced far sweeping reforms( forced or otherwise) , when he was just running a minority Govt dependent on allies support. #PVNarasimhaRao

Heading a minority Govt,PVNR managed to pass through crucial bills on economy, not a mean feat at all. He had to deal with the Nehruvian-Socialist lobby in his own party, apart from the Left, but managed to push through the economic reforms. #PVNarsimhaRao

1/14 How do e-cigarettes (ECs) affect cigarette smoking among youth? My new paper with @FloeFoxon simulates each scenario and finds out which one best matches actual trends... https://t.co/dBB7kcnTls @jgitchell @mikepesko @SwitchFinder @jkelovuori @TobPolicy @Clive_Bates

2/14 First, let's talk about why this question is so difficult to answer: COUNTERFACTUALS. We can't know the alternate-reality answers, like which smokers would have never started in a world without ECs, and which nonsmokers would now be smoking without ECs as an option.

3/14 So, the best we can do is use fancy/sophisticated methodologies to estimate what would have happened to youth smoking rates in the absence of ECs. In our case, simulation modeling

4/14 First, we look at the declining smoking trends *that were already happening* before ECs came (~2010), and project them into the present. This is our BASE-CASE SCENARIO about what smoking trends would be if ECs were never invented. Actual trends were LOWER than this base-case

5/14 Side note about terminology: We use the term “catalyst” instead of “gateway,” because “catalyst” is more precise about the claim we are modeling (that ECs are used first, and then causally lead to smoking). Whereas "gateway" can include other mechanisms like renormalization.

Academic staff at universities can't be open about the complaints against them - and most complaints of transphobia from students seem to be directed at staff. I'm just a final year PhD student, under no contractual requirement to be confidential, so I can share.

The original complaint against me was typical of the sort of thing directed at many female professional academics (and some male too). The strategies employed by my complainants are commonly used.

One of these is to perform vulnerability while behaving aggressively. Performing vulnerability is essential in order to trigger the university's awareness of its duties under the Equality Act, and establish an oppressor/victim dynamic to the case from the outset.

My complainants did this effectively. The complaint was initiated by a fellow PhD student, who joined forces with the SU. A student from the SU wrote the actual complaint. This is how it begins:

In all my dealings with @HuddersfieldUni I accepted that sometimes anonymous complaints were necessary - and that, sometimes, victimisation could be a concern. However, I have never victimised anyone. Nobody has ever argued that I have.

@danielashby @AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd I'll bite. Let's try to keep it factual. There's a reasonable basis to some aspects of this question, that it might be possible to agree on. Then there are other, more variable, elements which depend on external factors such as transport and energy policy. /1

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd First up, we know reasonably well how much energy it takes to propel a high-speed train along the HS2 route. We can translate that into effective CO2 generated by making some assumptions about how green the electricity grid is. /2

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Secondly, we have a reasonable grasp of how much CO2 is going to be generated by building HS2 - there are standard methods of working this out, based on the amount of steel, concrete, earthmoving, machine-fuelling etc required. /3

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Thirdly, we can estimate how much CO2 is generated by cutting down trees, and how much is captured by planting new trees. We can also estimate how much CO2 is needed to keep the railway running and generated by maintaining the track /4

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd We know how much CO2 is saved by moving goods by freight train on the lines freed up by moving the express trains on to HS2, rather than by truck. /5
