Portuguese railways: An experiment in human compression

 On Sunday, October 18, I was returning to Coimbra from Galicia by train, boarding in Valença, just across the border from Spain. The journey is supposed to take roughly three and a half hours. I should mention that I am a big fan of trains because they offer considerably more freedom than traveling by car. You can read, watch a movie, sleep, or even get some work done. Indeed, I was planning to spend the journey working on my laptop. Since I am an hourly-paid contractor these days, this meant I could literally get paid while traveling. What could possibly go wrong?

Ordinarily, the regional trains on this route provide the kind of accommodation one might reasonably expect for a journey of this length. Comfortable enough seats, electrical outlets, and some recognition of the fact that passengers may wish to spend several hours sitting down. There is also usually a nice folding table for your laptop. Unfortunately, this time the Portuguese railway operator, CP, had other plans.

The train waiting for us in Valença appeared to be a suburban commuter unit. Imagine a city bus placed on railway tracks, designed to carry people across town, and then imagine being asked to spend three and a half hours in it. The seats were intended for short trips, the accommodation was minimal, and the capacity was clearly inadequate. Still, I had boarded in Valença, so at least I managed to get a seat. As for the absence of a table, well, there is a reason they call it a laptop. I put the computer on my lap and started working. As it turned out, having a seat was a privilege I had seriously underestimated.

As we traveled south, I began to notice, out of the corner of my eye, that more and more passengers were boarding. I was concentrating on my work, so it took me a while to appreciate the scale of the problem. Eventually, the train became increasingly crowded, with people standing everywhere. By the time we reached Barcelos, it was obvious that the train could not accommodate everyone who wanted to board.

This was particularly interesting because CP had been selling tickets for the service. Presumably, there should be some relationship between the number of tickets sold and the capacity of the train provided. These were paying customers, after all, whose desire to travel should hardly have come as a surprise. Somewhere in the planning process, however, someone had apparently decided that the number of passengers had no necessary relationship with the number of people who could fit on the train.

Then things became more interesting. The train backed out of Barcelos station. Why? Nobody seemed entirely sure. We reversed for a while and stopped. At this point, I entertained several theories. Perhaps we had forgotten a passenger. Perhaps the driver had taken a wrong turn. Perhaps CP had discovered that Coimbra was, somehow, in the opposite direction.

Eventually, it became apparent that they were trying to solve the capacity problem by adding another train in Barcelos. This was probably a sensible idea, although it might have been even more sensible to make that decision before the original train became overcrowded. Arranging the additional capacity, however, required an extraordinary amount of time.

There was an additional complication. This was the last train to Coimbra that day. Leaving passengers behind would have been quite an achievement, even by the standards already established. Eventually, we got moving again, and for a brief moment, I thought the situation had been resolved. Then, when we reached Porto, the railway staff instructed us to change trains, and we dutifully complied.

I lost my seat.

Consider the sequence of events. I had boarded in Valença, secured a seat, and spent part of the journey productively working on my laptop. CP then discovered that it had insufficient capacity, interrupted the journey, located another train, and reorganized the passengers. The result was that I found myself standing in another train, unable to continue working. CP had somehow managed to increase the number of available trains while reducing my personal comfort and eliminating my ability to earn money during the journey.

This was quite an accomplishment. I had started the journey seated, with a laptop and a source of income. The railway company had intervened to improve the situation, and I was now standing, holding a laptop that had suddenly become unemployed.

At this point, I considered asking the conductor for a certificate documenting the delay, something that might help with a complaint or compensation claim. The difficulty was locating the conductor. Given the mood of the passengers, I suspected that the conductor had developed a perfectly reasonable interest in remaining somewhere else. I could hardly blame him. He was probably having a considerably worse day than I was, although presumably he was still being paid for it.

I should emphasize that the situation was not the result of a natural disaster, a terrorist attack, or a sudden geological event that had severed the railway. This was an ordinary train journey between two Portuguese cities, along an established railway line, with passengers who had purchased tickets. Somehow, CP had managed to turn it into an improvised transportation exercise.

I have spent much of my career studying the brain. One of my research interests is how behavior emerges from neural systems, and how relatively simple processes can produce unexpectedly complicated outcomes. The Portuguese railway system suggests an entirely new line of research. I would particularly like to identify the neural mechanisms involved in selling tickets for a train, providing insufficient capacity, and then appearing genuinely surprised when the passengers turn up.

There may be an Ig Nobel Prize in it.

Portugal: A field report on the difficulty of doing simple things

When we decided to spend a year in Portugal, I had certain expectations. Good food, excellent weather, historical cities, a slower pace of life, and the opportunity for the children to experience living in another country.

I also expected occasional bureaucratic absurdities. After all, I grew up in Spain. Nobody raised on the Iberian Peninsula expects the authorities to make life easy. In Spain, obtaining a document can require presenting another document certifying that you have requested the document needed to request the original document. This is perfectly normal. We have been doing it for centuries.

Portugal, however, has taken things in an interesting direction. After several months in Coimbra, I have come to believe that the Portuguese have developed an almost artistic ability to complicate tasks that nobody had previously considered difficult. Their achievements in architecture, navigation, literature, and gastronomy are undeniable. Their ability to connect a dishwasher to a water supply is more open to debate.

I have been collecting observations and what will follow is my preliminary report.

As outras linguas son irrelevantes

O curioso desta historia é que algo que para min é obvio, resulta absolutamente absurdo ou sinxelamente é irrelevante para unha gran parte da poboación do reino de España. Entre as cales se atopa a cónsul en Chicago.

Vaia por diante que as poucas veces que fun ao consulado o trato foi axeitado e a competencia dos que alí traballan foi salientábel. Por outra banda, fóra diso o trato que teño coa oficina consular é nulo. Onte chegou un email do consulado desexándome bo natal e a verdade é que normalmente tería rematado no lixo virtual se non fose por un detalle. Mirade o correo en cuestión:



Está mirado? Ben. Notades algo raro? Resulta que o cartón de Natal electrónico está en español, o cal é unha opción obvia, e tamén en inglés, que tamén é lóxico dada a localización. Ou pouco máis raro é que tamén estea en francés, ruso, chinés e árabe. Entendo que a idea é ser internacionais o cal desde logo eu non vou criticar porque é boa cousa. O meu problema xurde coas ausencias, as do catalán, o basco e o galego. Supoño que será porque non son linguas españolas...

Feliz Natal!

Cousas que un debe facer cando visita os EUA: disparar

Unha das preguntas máis habituais que me fai a xente en Galiza cando digo que vivo nos EUA é se xa merquei unha pistola. Deixando a un lado as consideracións morais, o certo é que ter unha arma en Chicago é bastante complexo. Na cidade a posesión de pistolas era ilegal até hai moi pouco (cando a corte suprema decretou a lei anticonstitucional) e incluso agora a posesión de armas está extremadamente regulada. En esencia, ademais de ter que rexistrarse coa policía, as armas só poden terse na casa (por exemplo: o garaxe e o alpendre non se consideran parte da casa para efectos da lei), e deben transportarse desmontadas. Por se isto non fose abondo, as tendas de armas son ilegais na cidade de Chicago.



Afortunadamente, existen lugares máis civilizados como Cincinnati (Ohío) onde este tipo de consideración son innecesarias e un pode adicarse a ese fermoso pasatempo que é dispararlle a cousas sen que medien gobernos entrometidos. Así que aproveitando a fin de semana, aí fumos a ver cal é o atractivo do asunto. Como son un home sensíbel, escollín para comezar un clásico cun calibre razoábel, unha Ruger MKIII cal. 22. E como non todo o mundo é coma min, un dos nosos amigos escolleu a nada sensíbel Glock 21. Moi semellante á polivalente Glock 17 en deseño, pero como os 9mm quédanlle pequenos ao redneck medio, os austríacos foron moi listos e sacaron para o mercado americano unha versión 45 ACP... unha semiautomática como deus manda, vaia.

A sensibilidade e a delicadeza feitas pistola: Ruger MKIII
Porque o tamaño (das balas) importa: Glock 21

A pesar do pouco aprezo que lle teñen en Ohío ao nanny state, un ten que seguir unha serie de regras básicas na galería de tiro, a miña norma favorita é sempre tratar unha pistola coma se estivese cargada. Semella que os Borbóns prefiren ignorar esta regra, o cal serve para dar de comer á prensa do corazón e aos historiadores.

Eu sendo sensíbel coa Ruger
Calquera que teña disparado unha espingarda de balíns pode comprender en que consiste o de dispararlle a brancos a diferentes distancias. A MKIII definitivamente ten moito disto en canto a peso e comportamento, até o punto de que a miña pontaría foi bastante boa e a sensación foi de estar a disparar nunha feira. A maior diferenza cunha feira era a Glock 21 no posto do lado que facía un ruído da ostía (mellor descrición posíbel). Pasar da Ruger á Glock foi como pasar de facerlle agarimos a un gatiño a espertar un león dándolle unha patada nos collóns. Facer dous tiros seguidos sen voltar a ter que apuntar é imposíbel, con independencia de canto te amarres á pistola. Desde logo, aqueles que buscan sensación de poder ao disparar unha pistola, deben decantarse pola Glock.

A miña sensibilidade foi ao carallo tras disparar coa Glock
O meco de papel está moi morto despois da miña falla de sensibilidade

Así que xa sabedes, se queredes matar follas de papel (tamén as hai con tipos ameazantes ou zombies), visitade Cincinnati porque disto en Chicago non hai.

O que o ministro de Educación non dixo

Pois o que non dixo foi isto:


"El ministro de Educación, Cultura y Deporte, José Ignacio Wert, ha anunciado este jueves que desarrollará "medidas de puesta en valor de la educación, y ayudas de acción y promoción cultural en el mundo de la educación". Para todo ello, se comprometió a convocar la Comisión Consultiva Nacional de Asuntos Educativos, y ha añadido que el Ministerio "participará activamente en las iniciativas nacionales e internacionales" que se emprendan para considerar a la educación "patrimonio inmaterial"."


En época de crise hai que ter as prioridades claras, home!

Confirmado


Por se alguén tiña algunha dúbida, Mariano Rajoy vai ser o próximo presidente do goberno. Entre unha chea de declaracións de boa vontade e referencias á grandeza de España, mencionou que quere ser presidente de todos os españois. A verdade é que esa é unha declaración que me preocupa por parte dalguén que foi un gran estudante de dereito, ao fin, para ser o presidente de todos os españois, España tería que ser unha república.

Este debe ser o detalle máis irrelevante de todo o discurso, pero prefiro un presidente do goberno que se debe aos seus votantes a un que se debe a algo tan difuso como todos os españois.

A importancia da sincronía

Para variar, vou falar un pouquiño de algo que nos afecta a todos: o desfase horario entre a hora solar e a hora peninsular.

Primeiro ollade este mapa, tede en conta que a cor verde indica que o Sol acada o punto máis alto antes de medio día e o vermello despois. Unha zona cun verde intenso terá un mencer temperán e un solpor temperán e, deste xeito, unha zona cun vermello intenso terá un mencer tardío e un sopor tardío.


É sinxelo reparar que Galiza é bastante vemella, hai sitios peores, iso si. Tamén é obvio que os portugueses o levan un pouco mellor cá nós.

O tema podería parecer absolutamente arbitrario e até irrelevante se non fose porque os seres humanos son entes biolóxicos e os ciclos de luz e escuridade son algo esencial para o funcionamento ótimo do noso corpo.

Sen liarme demasiado, na base do cerebro hai un reloxo mestre que regula os rítmos circadianos de todo o organismo. Este reloxo denomínase Núcleo Supraquiasmático, e é tan importante que recibe a súa propia información visual independentemente da que viaxa ao córtex visual.

Fonte: http://en.wikipedia.org/wiki/Suprachiasmatic_nucleus

Os seres humanos evoluíron como animais diurnos, e o noso corpo está preparado para realizar actividades físicas durante os períodos de luz e ir durmir, en si mesma unha actividade fundamental e tan complexa como a vixilia, nos períodos de escuridade.

As consecuencias de desaxustar o reloxo dependen da gravidade do desaxuste, pero en xeral soen levar a un acurtamento da esperanza de vida e supoñen un factor de risco para doenzas metabólicas (como a diabetes) e trastornos mentais.

O fuso ou fusos horarios nos que se atopa un país son decididos de xeito político, por eso o mapa amosa desfases, pero o ideal é que a hora solar se aproxime á hora oficial. Un cambio neste senso levaría de xeito inmediato a unha mellora da calidade de vida dos habitantes.

Por outra banda, existen múltiples exemplos de países con múltiples fusos horarios (USA e Rusia, por exemplo) e iso non supón un grave problema para os seus habitantes. Homoxeneizar a toda a poboación nun único fuso horario, por motivos políticos, é un erro, un erro biolóxico.
