North Korean nuclear submarines

Submarine-launched nuclear missiles are the ultimate deterrent, because unless your enemies are sure they can find and destroy all your subs before they have a chance to launch, you have the ability to retaliate anywhere at anytime, even if this is your last action after your enemy has turned your country into a “sea of fire” (as the North Koreans are fond of saying). If you read the first half of this CNN article, you think North Korea has them or almost has them, but if you get to the end you find out that the expert consensus is that North Korea isn’t close.

The US military has detected “highly unusual and unprecedented levels” of North Korean submarine activity and evidence of an “ejection test” in the days following Pyongyang’s second intercontinental ballistic missile launch this month, a defense official told CNN on Monday.

An ejection test examines a missile’s “cold-launch system,” which uses high pressure steam to propel a missile out of the launch canister into the air before its engines ignite. That helps prevent flames and heat from the engine from damaging either the submarine, submersible barge or any nearby equipment used to launch the missile.

Two concerns: one is that Trump decides they are close and decides to order a preemptive strike. Even if this were the best course of action, Trump is not the leader we would need at the helm during such a crisis. Two is that these might be the same experts what brung us weapons of mass destruction in Iraq. Maybe this is their makeup call for the earlier bad call. In other words, maybe we’re in for an unpleasant WMD surprise that goes in the opposite direction of the last one.

The current US intelligence assessment is that the missile program aboard submarines remains in the very early stages.

annuities

Annuities – I admit they sound like a boring topic. But what is not boring us thinking about you might want to do with your relatively short life of earth, and thinking outside the box about the tools available to you. Annuities are one of those tools.

Fixed SPIAs make retirement planning easier in exactly the same way that traditional pensions do: They’re predictable. If you know that you need $X of income each year in retirement, you can go to an online annuity quote provider, put in $X as the payout, check “yes” for inflation adjustments, and you’ll get an answer: “For $Y, you can purchase an annuity that will pay you $X per year, adjusted for inflation, for the rest of your life — no matter how long you might live.”

Pretty easy, right? You now have a specific figure for the minimum amount of savings necessary to retire safely. With a traditional stock and bond portfolio, retirement planning is more of a guessing game.

Fixed SPIAs are also helpful because they allow you to retire on less money than you would need with a typical stock/bond portfolio.

You could work hard and live frugally while you are young, then turn over your savings to an insurance company at some point and continue to live without working hard. People typically do this at retirement age (i.e. when they are old), but you could do it at a younger age and continue to live frugally without working hard, or you could work part time and pursue a passion part time, or you could spend more time with young children than hard working middle aged parents typically do, or you could take the risk of starting a business knowing that failure wouldn’t ruin you. You could turn over part of your savings, continue to work somewhat hard, and pursue some combination of any of the things on my list above. You could make gradual transitions from one mix of activities to another.

Now, do I really practice what I am preaching here? No. I work like a dog to support a family. I’m a conservative person, and I particularly worry about my ability to meet the costs of health care and education in the future. But I also ask myself each day what choices I am making right now that I might regret when I am looking back some day.

 

nuclear proliferation and non-state actors

This post on Lawfare talks about three ways people and groups other than nation-states could get their hands on nuclear weapons.

That entails blocking the pathways to terrorist acquisition of a nuclear weapon. There are three possibilities for how a terrorist organization might acquire the bomb: transfer—the sale or handoff of a weapon from a nuclear-weapon state; leakage—the theft of a nuclear weapon or weapons-grade fissile material; and indigenous production—the construction of a nuclear device from illicitly obtained weapons-grade fissile material.

Each pathway to nuclear acquisition by a non-state terrorist group is contingent on an act of commission or negligence by a state. The “leakage” of a weapon to a terrorist group would originate from one of the nine nuclear-weapon states or the 22 states (at current count) with weapons-grade fissile material in their civilian stocks. Among this group, the countries of greatest concern regarding the nexus of proliferation and terrorism—North Korea, Pakistan, and Russia—are each continuing their development of nuclear weapons and risking broader proliferation, including to non-state actors.

North Korea is on the verge of a strategic breakout both quantitatively, by ramping up its number of warheads to possibly as many as 100 weapons by 2020, and qualitatively, by mastering warhead miniaturization. And it would have few qualms about selling nuclear materials for the right price. Pyongyang is known, as Secretary of Defense Robert Gates put it, for its willingness to “sell anything they have to anybody who has the cash to buy it.” Pakistan continues to build up its nuclear arsenal (including the development of battlefield tactical nuclear weapons), employs terrorism as an instrument of state policy, and faces the internal security threat of radical Islamists attempting to infiltrate its nuclear establishment. And Russia, which inherited the Soviet Union’s vast nuclear arsenal and stocks of fissile material, terminated its nuclear-security cooperation with the United States under the Cooperative Threat Reduction Program put in place by the Nunn-Lugar Act in 1991.

a “soft military coup” for the U.S.?

This New Republic article is clearly very partisan. But it points out some concerns about three active or very recently retired generals being given unprecedented power over our country.

His complete failure to grow into the job has allowed multiple power centers to emerge and vie for ascendency within the administration. It has impelled other institutional actors to essentially expropriate from Trump governing tasks that should be his exclusively. In some cases, as when he gave military leaders a free hand in fighting terrorism, he has willingly parted with these obligations. In others, as when Congress wrested discretion over Russian sanctions away from him, he has been layered over reluctantly.

But the most alarming development is the one that ironically has official Washington the most relieved: the emergence of a trio of military officers (two retired, one actively serving) as de facto caretakers of the presidency.

It is perfectly consistent to say that the growing clout of generals John Kelly (the White House chief of staff), H.R. McMaster (the national security advisor), and Jim Mattis (the defense secretary) is preferable to an alternative in which Trump shambles through his presidency unencumbered, but also dangerous in its own right, and evidence of serious institutional failure. The hope is apparently to keep Trump’s administration within certain guardrails, so that if and when it fails, he doesn’t take the country and the world off the road with him.

If there is some kind of international crisis, I think I feel more comfortable with these guys making decisions than Trump. But I don’t like the idea that we have the military in charge rather than the civilian leadership, because they are very likely to come up with military solutions to problems. I always thought Trump would be lazy and delegate a lot of his job to subordinates, but this has taken a disturbing turn. It seems unlikely that Trump would be removed from office by Congress in the next four years, so at the moment I am hoping to avoid any major geopolitical crises through luck, and that someone will convince him not to run for reelection.

police officers accidentally film themselves planting evidence

According to the Intercept,

Last month, the city public defender’s office discovered body camera footage showing a local cop placing a bag of heroin in a pile of a trash in an alley. The cop, unaware he was being filmed, walked out of the alley, “turned on” his camera, and went back to “find” the drugs. The cop then arrested a man for the heroin, placed him in jail. The man, who couldn’t afford to post the $50,000 bail, languished there for seven months. He was finally released two weeks ago, after the public defender’s office sent the video to the state attorney.

So, I think I support the body cameras, I don’t really see why honest police officers wouldn’t support them too. Maybe they shouldn’t even have an “off” button.

solar phone chargers

I love the idea of charging my phone and other small devices with solar power. So, here is a Wirecutter article on doing that. One thing I learned is that you generally want to pair your solar panel with a battery so you can charge the battery during the day, then charge your phone all night. Otherwise you would have to leave your phone sitting near the charger for several hours during the day, which is probably exactly when you want to be using your phone for other things.

200,000 annual deaths from air pollution in the U.S.

A 2013 study estimated the number of annual premature deaths due to air pollution in the U.S. at about 200,000. That’s kind of a shocking number considering it is more than deaths from other preventable causes like car accidents and suicides. An interesting (not in a good way) finding is that road transportation causes more deaths (~53,000/yr) from air pollution than from crashes. On the other hand, it means you can kill two birds with one stone when you institute policies and technologies that reduce vehicle emissions, driving, or both. Of course, a shift to electric cars just shifts the emissions to power plants in the short term, but that means many fewer centralized sources of emissions, which might be easier to deal with. A shift to more muscle-powered transportation in our cities is a huge win in terms of health (less violent death and injuries, less death from dirty air, more exercise in all that clean fresh air, probably better mental health), and a win in terms of land use and vibrancy and getting to know one another in our cities.

Air pollution and early deaths in the United States. Part I: Quantifying the impact of major sectors in 2005

Combustion emissions adversely impact air quality and human health. A multiscale air quality model is applied to assess the health impacts of major emissions sectors in United States. Emissions are classified according to six different sources: electric power generation, industry, commercial and residential sources, road transportation, marine transportation and rail transportation. Epidemiological evidence is used to relate long-term population exposure to sector-induced changes in the concentrations of PM2.5 and ozone to incidences of premature death. Total combustion emissions in the U.S. account for about 200,000 (90% CI: 90,000–362,000) premature deaths per year in the U.S. due to changes in PM2.5 concentrations, and about 10,000 (90% CI: −1000 to 21,000) deaths due to changes in ozone concentrations. The largest contributors for both pollutant-related mortalities are road transportation, causing ∼53,000 (90% CI: 24,000–95,000) PM2.5-related deaths and ∼5000 (90% CI: −900 to 11,000) ozone-related early deaths per year, and power generation, causing ∼52,000 (90% CI: 23,000–94,000) PM2.5-related and ∼2000 (90% CI: −300 to 4000) ozone-related premature mortalities per year. Industrial emissions contribute to ∼41,000 (90% CI: 18,000–74,000) early deaths from PM2.5 and ∼2000 (90% CI: 0–4000) early deaths from ozone. The results are indicative of the extent to which policy measures could be undertaken in order to mitigate the impact of specific emissions from different sectors — in particular black carbon emissions from road transportation and sulfur dioxide emissions from power generation.

eyes on the street

A group at the University of Pennsylvania looked for statistical evidence that “eyes on the street” are a deterrent to crime. The results are a bit puzzling, as real world data often can be.

ANALYSIS OF URBAN VIBRANCY AND SAFETY IN PHILADELPHIA

Statistical analyses of urban environments have been recently improved through publicly available high resolution data and mapping technologies that have adopted across industries. These technologies allow us to create metrics to empirically investigate urban design principles of the past half-century. Philadelphia is an interesting case study for this work, with its rapid urban development and population increase in the last decade. We focus on features of what urban planners call vibrancy: measures of positive, healthy activity or energy in an area. Historically, vibrancy has been very challenging to measure empirically. We explore the association between safety (violent and non-violent crime) and features of local neighborhood vibrancy such as population, economic measures and land use zoning. Despite rhetoric about the negative effects of population density in the 1960s and 70s, we find very little association between crime and population density. Measures based on land use zoning are not an adequate description of local vibrancy and so we construct a database and set of measures of business activity in each neighborhood. We employ several matching analyses within census block groups to explore the relationship between neighborhood vibrancy and safety at a higher resolution. We fi nd that neighborhoods with more vacancy have higher crime but within neighborhoods, crimes tend not to be located near vacant properties. We also find that more crimes occur near business locations but businesses that are active (open) for longer periods are associated with fewer crimes.

This is particularly fascinating to me because I live my life in the middle of this particular data set and am part of it. So it is very interesting to compare what the data seem to be saying with my own experiences and impressions.

The lack of correlation between population density and crime is not surprising. Two neighborhoods with identical density can be drastically different. The correlation between poverty and crime is not surprising – people who are not succeeding in the formal economy and who are not mobile turn to the informal economy, in other words drug dealing, loan sharking and other illegal ways of trying to earn an income. If they are successful at earning an income, they tend to have a lot of cash around, and other people who know about the cash will take advantage of them, knowing they will not go to the police. Other than going to the police, the remaining options are to be taken advantage of repeatedly, or to retaliate. This is how violence escalates, I believe, and it goes hand in hand with development of a culture that tolerates and even celebrates violence, in a never-ending feedback loop.

The puzzling part comes when they try to drill down and look at explanatory factors at a very fine spatial scale. They found a correlation between crime and mixed use zoning, which appears to contradict the idea that eyes on the street around the clock will help to deter crime. And they found more crime around businesses like cafes, restaurants, bars and retail shops. They found that longer open hours seemed to have some deterrent effect on crime relative to shorter open hours.

I think they have made an excellent effort to do this, and I am not sure it can be done a lot better, but I will point out one idea I have. They talk about some limitations and nuances of their data, but one they do not mention is the idea that they are looking at reported crimes, most likely police reports or 911 calls. It could be that business owners, staff and patrons are much more likely to call 911 and report a crime than are residential neighbors. The business staff and patrons may see this as being in the economic interest, increasing the safety of their families, and the (alleged) criminals they are reporting are generally strangers. In quieter all-residential neighborhoods, people may not observe as many of the crimes that do occur (fewer “eyes on the street”), they may prefer not to report crimes either through a sense of loyalty to one’s neighbors, minding one’s own business, quid pro quo, or in some cases a fear of retaliation. There is also the factor of some demographic groups trusting the police more than others, although the authors’ statistical attempts to control for demographics may tend to factor this out.

 

July 2017 in Review

Most frightening stories:

Most hopeful stories:

  • A new cancer treatment genetically modifies a patient’s own immune system to attack cancer cells.
  • Shareholders of big fossil fuel companies are starting to force some action on climate change business risk disclosure.
  • Richard Florida offers five ideas for solving poverty and what is wrong with cities: taxing land based on its improved value, massive investment in public transportation and public education, ending the mortgage interest tax deduction, and guaranteed minimum income.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • Technology is marching on, whether or not the economy and human species are. The new thing with satellites is to have lots of small, cheap ones instead of a few big, expensive ones. Even if the coal industry were to make a comeback, today’s coal jobs are going to data analysts, remote control machine operators, mechanical and electrical engineers, not guys underground with pickaxes and headlamps. But the coal can be produced with a lot less human effort (i.e. jobs) than it used to be. Iris scans like in Minority Report are now a thing.
  • Ecologists have some new ideas for measuring resilience of ecosystems. Technologists have some wild ideas to have robots directly counteract the effects of humans on ecosystems. I like ideas – how do I get a (well-compensated) job where I can just sit around and think up ideas?
  • Isaac Asimov says truly creative people (1) are weird and (2) generally work alone.

Some combination of the Trump news, the things I see every day on the streets of Philadelphia, and events affecting friends and family led me to question this month whether the United States is really a society in decline. Actually, I don’t question that, I think the answer is yes. But the more important question is whether it is a temporary or permanent decline, and what it means for the rest of the globe. I am leaning slightly toward permanent, but maybe I will feel better next month, we’ll see. Maybe I need to get out of this country for a little while. Last time I did that I felt that the social glue holding Americans together is actually pretty strong compared to most other places, even if our government and its approach to other governments have become largely dysfunctional. We need to get through the next couple years without a nuclear detonation, hope the current vacuum of leadership leads some quality leaders to emerge, and hope things have nowhere to go but up. There, I talked myself off the ledge!
