    1. emma o kelly [@emma_okelly]. (2021, December 6). I was @scoilidepps today looking at ventilation. Built in 60’s with dual aspect classrooms for cross ventilation. Handy outdoor ‘corridors’ too. All designed to prevent the spread of TB. School has also bought HEPA filters for classes. Re Covid it has managed pretty well so far. Https://t.co/KgZgABDeDL [Tweet].

    1. David Fisman. (2021, December 15). HEPA air cleaners in hospital...lets compare cost to ECMO. ECMO course in the US costs around $93,000 CDN; US cost:charge ratio is around 0.2, so let’s say that’s $20,000 CDN. That’s the cost of 50 high end hepa air cleaners! Or you could do 250 CR boxes at around $80 a pop. [Tweet]. @DFisman. https://twitter.com/DFisman/status/1471259305961828355

    1. Faktor geologi berupa endapan alluvial yang memiliki permeabilitas umumnya rendah dan berada pada topografi landai hingga datar menyebabkan terjadinya intrusi air laut terhadap airtanah dangkal.

      Penyebab intrusi air laut disebabkan oleh jenis material dan juga adanya pengaruh topografi. Sehingga dalam penentuan daerah intrusi air laut hal yang perlu diperhatikan terlebih dahulu ialah apakah material di daerah tersebut memiliki parameter aquifer yang mendukung adanya transport air laut kedaratan, seperti permeabiltas dan porositas.

    2. Pengambilan sampel diperoleh dari sumur gali penduduk sebanyak 100 sampel (n=100) pada periode Maret-Juli 2019 dengan variasi jarak dari pantai 0,04-5,52 km dan elevasi muka airtanah (MAT) antara 0,43-30,01 mdpl.

      Data yang diambil dalam penelitian ini ialah data sumur gali, elevasi, dan juga pada saat kapan data itu diambil. Sehingga untuk peneliti selanjutnya dapat melakukan hal yang sama dan hanya mengkomparasi antara data sebelumnya dan data yang didapatkan.

    1. Svelte’s aesthetics feel like a warm cozy blanket on the stormy web.
    2. Making UIs with Svelte is a pleasure. Svelte’s aesthetics feel like a warm cozy blanket on the stormy web. This impacts everything — features, documentation, syntax, semantics, performance, framework internals, npm install size, the welcoming and helpful community attitude, and its collegial open development and RFCs — it all oozes good taste. Its API is tight, powerful, and good looking — I’d point to actions and stores to support this praise, but really, the whole is what feels so good. The aesthetics of underlying technologies have a way of leaking into the end user experience.

    1. (d) All calculations shown in this appendix shall be implemented on a site-level basis. Site level concentration data shall be processed as follows: (1) The default dataset for PM2.5 mass concentrations for a site shall consist of the measured concentrations recorded from the designated primary monitor(s). All daily values produced by the primary monitor are considered part of the site record; this includes all creditable samples and all extra samples. (2) Data for the primary monitors shall be augmented as much as possible with data from collocated monitors. If a valid daily value is not produced by the primary monitor for a particular day (scheduled or otherwise), but a value is available from a collocated monitor, then that collocated value shall be considered part of the combined site data record. If more than one collocated daily value is available, the average of those valid collocated values shall be used as the daily value. The data record resulting from this procedure is referred to as the “combined site data record.”
      1. Calculate mean of all collocated NON-primary monitors' values per day
      2. Coalesce primary monitor value with this calculated mean
    1. I’ll remember it again after the party’s over, she decided. And somehow that seemed quite the best plan...

      The use of the word quite again--it's like nothing is real, or embodied. There is a lot of flighty language and flighty characters, 'Laura flew' 'butterfly' descriptions of air, and wind, and puffs, and angels--nothing feels grounded. The characters and the place feel like they could just be blown away like dead dandelion puffs.

    1. Then at some moment I just stumbled upon limitations and inexpressiveness of templates and started to use JSX everywhere — and because JSX was not a typical thing for Vue I switched to React over time. I don’t want to make a step back.
    1. 1.1. Monitors For the purposes of AQS, a monitor does not refer to a specific piece of equipment. Instead, it reflects that a given pollutant (or other parameter) is being measured at a given site. Identified by: The site (state + county + site number) where the monitor is located AND The pollutant code AND POC – Parameter Occurrence Code. Used to uniquely identify a monitor if there is more than one device measuring the same pollutant at the same site. For example monitor IDs are usually written in the following way: SS-CCC-NNNN-PPPPP-Q where SS is the State FIPS code, CCC is the County FIPS code, and NNNN is the Site Number within the county (leading zeroes are always included for these fields), PPPPP is the AQS 5-digit parameter code, and Q is the POC. For example: 01-089-0014-44201-2 is Alabama, Madison County, Site Number 14, ozone monitor, POC 2.

      How monitors (specific measures of specific criteria) are identified in AQS data.

    1. Negative values included when assessing air quality In computing average pollutant concentrations, EPA includes recorded values that are below zero. EPA advised that this is consistent with NEPM AAQ procedures. Logically, however, the lowest possible value for air pollutant concentrations is zero. Either it is present, even if in very small amounts, or it is not. Negative values are an artefact of the measurement and recording process. Leaving negative values in the data introduces a negative bias, which potentially under represents actual concentrations of pollutants. We noted a considerable number of negative values recorded. For example, in 2016, negative values comprised 5.3 per cent of recorded hourly PM2.5 values, and 1.3 per cent of hourly PM10 values. When we excluded negative values from the calculation of one‐day averages, there were five more exceedance days for PM2.5 and one more for PM10 during 2016.

    1. the connections between the individuals and groups are studied. T

      The space between individuals is where the social capital resides. Where peer pressure occurs. Where norms are exchanged and regulated. It is an important space :-)!

    1. tudies the relationships we have

      I am a bit confused here...SNA focuses directly on the space between individuals. Our relationships live in this space. Traditional social science looks at the characteristics of individuals to see if they vary according to another variable, i.e. independent and dependent variables. There are no IV and DV in SNA, at least in basic SNA. More advanced SNA blends statistics and SNA data.

    1. networks the individual is a part of may have impacted that action.

      The focus of analysis is on the space between the individuals, i.e. the air, rather than on the character or traits of the individual. The traits and character can be used to understand what is going on in the relationship but SNA measures the links not the nodes.

    1. social relationships as a primary concern

      While traditional social science focuses on the characteristics of the individual, SNA takes the idea of social pressure and social forces seriously and analyzes the space in between individuals, i.e. the 'air'.

    1. all tied together

      This is what makes SNA so different. Usual sociological analysis holds the individual as the unit of analysis. Even when looking at the institutional level, the unit is usually the individual. SNA asks you to see, analyze and conceptualize the space between individuals, i.e. air.

    1. unit of study

      This is what makes SNA so different. Usual sociological analysis holds the individual as the unit of analysis. Even when looking at the institutional level, the unit is usually the individual. SNA asks you to see, analyze and conceptualize the space between individuals, i.e. air.

    1. just how important our social networks are to every aspect of our lives

      Social networks are like 'air'; they surround us and we don't even see them. To me, this is what makes the methodology of SNA harder to grasp; how to access the data for 'air'? How to understand the discreet influence of 'air'? But once you see it, you can't unsee it! Very powerful!

    1. what you see on the surface (individuals or bamboo shoots) is connected by a complicated path that run just below the surface (relationships between people or the root system of the bamboo plant).  

      I think this is why we are so fascinated by social media; it has revealed what has always been under the surface. To me, networks are like 'air'; all around us but hard to see. SNA reveals the air.

    1. networks are everywhere,

      I think this is why they are hard to analyze...it is like trying to see and understand air. It is everywhere so it feels so normal and invisible. Networks, particularly human networks are the same. Humans have always been embedded in networks; we live, thrive and die in networks. They are another form of 'air'. The difference is that today, social media has made them more visible. We can now see them and analyze them in new ways. Hence, why this class is online :-)

    1. new framework for understanding issues ranging from democracy on the web to the vulnerability of the internet and the spread of deadly viruses

      Sometimes this new framework feels a bit overwhelming to me because it asks me to 'see' the world differently. I am use to seeing through discreet categories containing individuals; i.e. race, class and gender. SNA is asking me to see it through interconnections and links--the stuff behind the categories. Sometimes it feels like I am being asked to see 'air'; I know it is there, but it is all around me--ubiquitous--which makes it harder, and more intellectually challenging, to see.
