1.4: Are you ready to get with the programming? - Geosciences

Meteorologists and atmospheric scientists spend much of their time thinking deep thoughts about the atmosphere, the weather, and weather forecasts. For those who are programming novices, we can introduce you to a few of the concepts of programming by getting you to use Excel or another similar spreadsheet program.

To help you learn and retain the concepts and skills that you will learn in this course, you will solve many word problems and simple math problems. For several activities, we give you the opportunity to practice solving particular types of problems enough times until you gain confidence that you can solve those same types of problems on a quiz. That means that you will be solving some types of problems several times and only the numbers for the variables will change. The simplest way for you to solve these problems is to program a spreadsheet to do that repetitive math for you.

Screenshot shows an Excel Spreadsheet

A text box says "put activity number in row 1" and an arrow points to cell A1.

A second text box says "put variable names in row 2" with an arrow pointing to cells A2 and B2

A third text box says "start numbers for variables in row 3" with an arrow pointing to cells A3 and B3

A final text box says "calculations follow variable numbers" with an arrow pointing to C3.

Let’s do a simple example. Suppose we have several boxes, some with different shapes and sizes, and we want to calculate the volume of the boxes and find the total volume. I have put in the names of the variables (with units!) and then the numbers for the length, width, and height of each box type and the total number of each box. To calculate the volume of each box, click on E3 and put an “= a3*b3*c3” in the equation line. Hit enter and it will do the calculation and put the answer in E3. A small square will appear in the lower right corner of E3. Click on this square with the mouse and pull down over the next three rows. Excel will automatically do the calculations for those rows. To calculate the total volume, go to F3 and enter “=d3*e3,” and hit “enter.” Grab the small box and pull down to get the total volume of each type of box. To get the total volume, click on F7, click on “Formulas,” and then “AutoSum,” and finally “Sum.” Excel will show you which cells it intends to sum. You can change this by adjusting the edges of the box it shows.

How do school districts use Impact Aid?

Most Impact Aid funds, except for the additional payments for children with disabilities and construction payments, are considered general aid to the recipient school districts these districts may use the funds in whatever manner they choose in accordance with their local and State requirements. Most recipients use these funds for current expenditures, but recipients may use the funds for other purposes such as capital expenditures. Some Impact Aid funds must be used for specific purposes. All payments are distributed by wire transfer directly to the bank accounts of school districts.

School districts use Impact Aid for a wide variety of expenses, including the salaries of teachers and teacher aides purchasing textbooks, computers, and other equipment after-school programs and remedial tutoring advanced placement classes and special enrichment programs. Payments for Children with Disabilities must be used for the extra costs of educating these children.

The famous DROP options are a way to name beneficiaries to your DROP and FRS Pension program.

Option 1

All the money to you, nothing to your beneficiaries. This is the highest payout for your self. You will get 100% of your pension.

Option 2

A 10 year period certain pay out. This means that your beneficiaries will get a benefit if you pass away within your first 10 years of retirement.

Example: Year 5 you pass away, your beneficiaries will get 5 years of your reduced pension.

The reduced cost of Option 2 will be approx. 5-10%. This number will vary depending you your age at retirement. With this option you will be able to pick a minor as a beneficiary. This is the only option that allows you to pick a minor.

Option 3

Option 3 is probably the most common option to pick. This option gives you the ability to pick your spouse as a beneficiary, and if you pass away, they will receive your pension for the rest of their lives.

There is a cost for picking this option. Your pension will be reduced between 15-25% depending on the age of your spouse.

Option 4

This option is a little strange as you elect to receive a sightly reduced pension (around %5) , and if either you or your beneficiary passes away then your pension gets cut to 2/3 what you where receiving.

1.4: Are you ready to get with the programming? - Geosciences

SuperDuper! v3.5, which is Big Sur compatible and produces bootable Intel and M1 backups, is now in Beta: see the Shirt Pocket blog for information.

Have no fear. SuperDuper v3.3.1 is here, and it includes full Catalina support!

SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. It's the perfect complement to Time Machine, allowing you to store a bootable backup alongside your Time Machine volume&mdashand it runs beautifully on your Mac!

Version 3.3.1 lets you ignore "missing drive" errors during scheduled copies, and also improves Smart Wake, which ensures your backups happen whether your Mac is awake or asleep. and won't turn on your screen if your Mac is already awake.

This new version also improves Smart Delete, an awesome new capability that minimizes the possibility of disk full errors while maintaining safety with no speed penalty, native Notification Center support, a Finder extension to quickly run copies, and other improvements. SuperDuper can even create and copy from snapshots, which means with an APFS backup drive, you can restore today's Smart Update, yesterday's, etc! It's super cool.

SuperDuper's interface confirms all your actions in simple, clear language to ensure that the end result is exactly what you intended. Take a look, and click for additional screen shots!

The SuperDuper! Main Window

We all know that using the Macintosh is usually a trouble-free experience.

Except when it's not. Like when:

  • Your hard drive starts making that horrible clicking noise that signals an imminent meltdown
  • A momentary lapse of coordination causes your MacBook Pro to take a dirt nap
  • The system suddenly fails to boot
  • Your most important day-to-day application isn't working with the system update you just applied
  • The new driver you just updated is causing your Macintosh to crash
  • That lousy software you just tried didn't come with an uninstaller, and scattered files all over your drive
  • You need to restore a stable copy of your system, but don't want to lose what you've been working on
  • You need to test new versions of the operating system with production data you can't afford to lose

It happens to all of us, eventually. And recovering can be a painful, error-prone, time-wasting experience, if it's even possible at all. Until now.

Carbon copies. And a whole lot more.

SuperDuper is the most advanced, yet easy to use disk copying program available for macOS. It can, of course, make a full backup, or "clone" &mdash in moments, you can completely duplicate your boot drive to another drive, partition, or image file. In even less time, you can update an existing clone with the latest data: use Smart Update and, minutes later, your backup is completely up to date!

Faster than a speeding bullet &ndash and more accurate!

SuperDuper isn't just the most powerful cloner available: it's incredibly fast, too. Its Smart Update feature evaluates hundreds of thousands of files and directories in just minutes, automatically updating your clone to reflect any changes you've made on the original drive &ndash including custom icons, HFS+ attributes, ownership changes. the works! It can even copy (and Smart Update) Time Machine backup volumes!

Expertise not required.

SuperDuper comes preconfigured, ready to perform all the most common copying and cloning tasks. We've pored over the Apple documentation so you don't have to. Every step of the process carefully follows all Apple recommended policies and procedures.

Whether you're making a full backup to a disk image, using Smart Update to update an existing backup, or making a complex clone to test a software update, the process couldn't be simpler: select the source drive, the destination and the appropriate script. Click Copy Now, and SuperDuper does the rest.

Doveryai no Proveryai.

Most companies would cherry-pick their feedback, and include selected quotes from happy customers. Sure, we could point you to our 4.5 5 star review from Macworld, or many other raves. We could even point you to our back-to-back 2005 and 2006 Eddy Awards!

But we're not going to do that. Instead, we encourage you to ask some friends, and look for yourself! Here's a simple Google query for "superduper macintosh review" to get you started.

(It means "Trust but Verify".)

Clones for experts.

Regular backups aren't always the best way to recover for the risk takers out there who jump on every software update. Unless you take specific steps, fully restoring a backup restores everything on the drive, overwriting both the system and user files. If that's what you want to do, great. But it usually isn't, because everything you've done since the backup would be lost!

With SuperDuper, though, you can easily "checkpoint" your system with a Sandbox, preserving your computer's critical applications and files while you run on a working, bootable copy. If anything goes wrong, just reboot to the original. When you do, your current Documents, Music, Pictures &mdash even iSync data &mdash are available! You can get back to work immediately!

Clones for industry!

SuperDuper has enough features to satisfy the advanced user, too. Its simple-but-powerful Copy Script feature allows complete control of exactly which files get copied, ignored, even aliased ("soft linked" for the Unix inclined) from one drive to another!

SuperDuper is perfect for software developers, software "seed" sites, QA testers, even system administrators:

  • Developers and Seed Sites
    Need to keep up to date with the most recent weekly build of a new operating system? Use the provided "Copy with Shared User Files and Applications" script, or create your own. A few clicks later and your clone is ready to upgrade, without unsafe downgrades, or unsupported "intermediate build" upgrades!
  • QA Testers
    Need to regress against a large number of operating system targets, or other types of fixed configurations? Simply save a series of images, and in minutes you can restore them and be ready to test.
  • System Administrators
    Need complete control over building a standard image for one, one hundred or one thousand systems? SuperDuper's Copy Scripts make it easy!

Get cloned.

Give SuperDuper a workout on your own system. Clone to your heart's content&mdashfor free. See what else is possible. When you're convinced that SuperDuper is a terrific solution&mdashand a great value at US$27.95 &mdashyou can click buy now, have the registration entered with a single click, and start using its advanced features immediately!

Geoscience: Ups and downs

Unsettled markets lead to shifting employment prospects for petroleum geoscientists.

Steep declines in oil prices have decimated oil companies' profits and squeezed a once-booming demand for petroleum geoscientists. In a one-two punch, the price of oil plunged to a 12-year low and energy companies were forced to shed tens of thousands of jobs and slash their oil- and gas-exploration budgets.

The situation is the worst for some time. In January, the price of oil fell to less than US$28 per barrel, down from more than $100 per barrel in 2014 — squashing short-term employment prospects for geologists and geophysicists. Shell, one of the sector's largest companies, has already announced the loss of about 10,000 jobs, and its competitors Chevron and BP have also revealed cuts that number in the thousands. Worldwide, graduate programmes that for decades have been the leading suppliers of talent to energy companies can no longer instantly place their freshly hatched master's-level geoscientists.

“We've had at least a 50% drop in hiring — some major companies are not hiring at all,” says Maurine Riess, director of the geosciences career centre at the University of Texas at Austin, which historically has been a main pipeline for energy-company recruitment. And the master's programme in integrated petroleum geoscience at the University of Aberdeen, UK, another long-time provider, has also felt the impact: last year, one-quarter of its graduates could not immediately get industry jobs. Some of those who were hired elsewhere found roles in risk analysis or finance — fields that are distant from those in which they have trained.

Energy analysts predict a dim outlook for those seeking positions in geoscience for at least the next year (see 'Survival tips for petroleum geoscientists'). But demand for expertise in geology and geophysics is expected to grow in the longer term across the oil and gas industries owing to a pending wave of retirements, a growing demand for technical and leadership skills and a continuing need for oil. Analysts also foresee an increasing demand for this expertise in the environmental sector, notably in impact mitigation — the development and implementation of ways to reduce or eliminate the effects of oil and gas exploration and extraction on the environment.

Instability is not unusual in the energy sector, and this most recent decline in the price of oil is due, very simply, to a glut of oil on the market. Between 2000 and 2008, the price of oil rose sharply and peaked at a record high of almost $150 per barrel. But then a global recession sent the price down to about $40 per barrel by the end of 2008. Although the subsequent economic recovery lifted the price over the next five years, by mid-2014, the price began to drop once more as demand decreased. And at the same time, production has risen in the Middle East, the United States and Canada. These factors have combined to create an unusual excess of oil.

Boom–bust cycles in the sector have produced an uneven workforce demographic that could actually mean good news for early-career geologists over the next five to ten years. The American Geosciences Institute (AGI) in Alexandria, Virginia, a network of associations that represents geoscientists, foresees a shortage of at least 135,000 professionals in the United States by 2022. Its forecast derives in part from the fact that many US geoscientists will soon be at or near retirement age. In academia, for example, the average faculty member in the United States is aged 60. “Half the industry's workforce is retiring in the next several years — with or without the downturn. That's a pretty big human-capacity gap that will have to get filled,” says Christopher Keane, the AGI's director of communications and technology.

boxed-textAnd despite the present oversupply, energy companies must still pursue a certain level of oil exploration to remain profitable, says Stephen Barnes, director of the Economics and Policy Research Group at Louisiana State University in Baton Rouge. Barnes, who tracks the workforce needs of the oil industry, says that the discovery of new oil fields, a chief component of exploratory missions, requires a high level of expertise. Keane says: “The million-dollar question — and we can't answer this because companies hold that info tight — is, how many companies prepare for a rebound ahead of time and staff accordingly?” Barnes adds that when the demand for new recruits ramps up, skilled geoscientists are likely to be sought first because their specialized knowledge will be required for exploratory missions.

The pending retirement wave and a closer focus on climate change and environmental issues, notably in the area of mitigation, will open up opportunities for geoscientists. And the environmental implications of oil exploration and extraction will be an important driver of workforce demand in the near future, predicts Carlos Dengo, a former ExxonMobil executive and current director of the Berg-Hughes Center for Petroleum and Sedimentary Systems at Texas A&M University in College Station.

Those who focus on subsurface geology have the expertise to develop climate-change mitigation strategies such as carbon capture and storage (CCS), which aims to trap carbon dioxide underground to reduce atmospheric levels of greenhouse gases. “There is no way the world can meet greenhouse-gas emission goals without CCS,” says Philip Ringrose, a specialist in CO2 storage and petroleum geoscience at Statoil in Trondheim, Norway.

At the moment, no one can pinpoint if or when the demand will ramp up. The cost of CCS — and a lack of clarity over who will pay for and insure projects — has meant that its adoption has been uneven. Last November, the UK government cancelled its £1-billion ($1.4-billion) proposed investment in CCS, but both Norway and Canada have government-funded CCS projects under way. Despite the uncertainty, says Ringrose, research funding for CCS has been increasing worldwide.

While the energy sector is in a downturn, geoscientists can look to other fields, Keane points out. In previous periods of decline, their geospatial skills were in demand from the telecommunications industry for the siting of mobile-phone networks, and their proficiency in quantitative-problem management made them highly sought after by finance companies.

Some energy analysts have questioned whether academia can produce the expertise that industry, governments and the non-profit sector will need over the next decade or so, given the ageing workforce and anticipation that the demand for training will exceed the capacity of existing programmes. The overall proportion of US federal funding that is allocated to academic geoscience research has fallen by half since the 1980s, when it represented 11% of basic-research funding. And any specific increases in funding for geoscience research have gone to the environmental or atmospheric sciences. The problem is exacerbated by the fact that geoscience departments in US and UK universities tend to rely on funding from the oil and gas industries, and that typically dwindles during downturns.

“When I started at Texas A&M 2 years ago, my centre had funding for 11 fellowships that came directly from industry. For 2016, I've got 4,” says Dengo. Up to 100 of the more than 400 geoscience master's programmes in the United States now produce most of the new employees for the oil and gas industries.

“Despite the ups and downs of this industry, it is surprising how much geoscience skills remain in demand.”

According to Dengo, these industries want to stop their pattern of slashing support during downturns, which compromises the interest and training of geoscientists. Some companies are eager to support efforts that combine industry and academic expertise to train PhD students. “We sponsor quite a lot of students and use that programme to find the ones we want to employ,” says Jonathan Craig, senior vice-president for exploration at Eni, an oil and gas company in Milan, Italy. And industry support has facilitated the creation of a training initiative in the United Kingdom. Eleven energy companies have contributed financially to the Natural Environment Research Council Centre for Doctoral Training (CDT) in Oil and Gas, located at Heriot-Watt University in Edinburgh, UK, where the British Geological Survey is also relocating 160 of its geoscientists.

With an investment of £10 million from the Natural Environment Research Council, industry and 17 universities, the CDT will produce at least 120 PhD graduates by 2021. Students conduct research and receive 20 weeks of training from industry experts who address the use of oil, energy regulation and the environmental impact of oil-related activities, among other topics.

Early-career geoscientists who receive training in these fundamentals could have an edge in the job market. CDT director John Underhill says that many industry executives complain that today's workforce lacks such a knowledge base. Four areas in particular — stratigraphy, structural geology, sedimentology and field geology — need to be bolstered to escape what he calls 'Nintendo' geology, an over-reliance on 3D mapping and visualization techniques.

Beyond a solid foundation in core geology, the most marketable geoscientists will also have strong quantitative and soft skills, which include communication, the ability to work in a team and sensitivity towards other cultures. To that end, Dengo has created three part-time teaching positions at Texas A&M that he will fill with former industry executives who can share their global experience and business acumen, as well as their specific areas of expertise.

The fundamental proficiency of geoscientists, their ability to remotely detect and assess what is happening within Earth, will prove most desirable both to employers in and outside the energy sector. “Despite the ups and downs of this industry, it is surprising how much geoscience skills remain in demand, even during difficult times,” says Ringrose.

Box 1: Survival tips for petroleum geoscientists

Early-career geoscientists should be aware that opportunities in the field will rise and fall with the price of oil. “The only constant in this industry is change, so be comfortable with that,” says Carlos Dengo, director of the Berg-Hughes Center for Petroleum and Sedimentary Systems at Texas A&M University in College Station. Here are some tips for working in the sector.

Demonstrate your critical-thinking and problem-solving abilities. This will underscore your aptitude for working with uncertainty and incomplete data.

Hone your interpersonal, cross-cultural and leadership skills. These are becoming increasingly important to oil and gas companies, according to Dengo.

Be ready to move to where the work is. “The oil industry is a global economy,” says Nick Schofield, director of the MSc in Integrated Petroleum Geosciences at the University of Aberdeen, UK.

Prepare yourself for an uncertain future. But also note that analysts predict that oil and gas will meet more than 40% of the global energy demand for the next 24 years.

Quantitative skills can boost job security. A strong mathematical background may give you an advantage during an industry downturn, suggest data from the American Geosciences Institute in Alexandria, Virginia, which tracks workforce trends.
