![]() The economist William Sharpe, in his 1964 paper on the Capital Asset Pricing Model and the analysis of market risk, revisited this super-efficient, optimal portfolio. Portfolios with more risk and less return would be rejected by investors, no matter their risk tolerance. Based on Markowitz’s MPT concepts of maximizing expected return based on a given level of market risk, Tobin suggested that there exists only one super-efficient portfolio in which a reasonable level of return can be achieved at a reasonable level of risk. ![]() Then in 1958, a Yale professor named James Tobin explored the concept of economic utility, or financial usefulness. His work is the basis of Modern Portfolio Theory or MPT. Return is defined as increases in value and risk as the unpredictability of prices usually represented by standard deviation. It all started in 1952 with a young economist named Harry Markowitz, who theorized that a portfolio of uncorrelated assets-in other words, assets whose prices react differently under similar environments-could be optimized such that: Three prominent Nobel Prize winners, instrumental in the study of investing, are also credited with understanding the benefits of the Global Market Portfolio. Whether for a nonprofit endowment or personal retirement, of all possible portfolios the Global Market Portfolio delivers the most return for the lowest risk as theorized by three renowned Nobel laureates. And while it won’t be the best performing portfolio on the block or even the most consistent, that’s the whole point. Dial down risk by holding more cash dial up risk by holding less. The beauty of the Global Market Portfolio is that can be used as a starting point for any investor, regardless of risk appetite. The Global Market Portfolio represents all assets-stocks, bonds, real estate, commodities, and other investments issued by governments and corporations-weighted in proportion to their relative market values. How does one navigate and mitigate risk with increasingly complex scenarios? Enter the Global Market Portfolio The past ten years have seen global expansion, global opportunity and increasing global risk. The innovation and evolution of the financial services sector allows Fairlight to deliver portfolios, once reserved for the mega-institutions or pension plans, with the same impact to a wide-range and size of nonprofits, whether emerging board-designated funds, 403 b retirement plans or established endowments. This experience was always grounded in the pioneering research of Nobel laureates and the importance of low-cost and accessible investment products for all types of investors.įor this reason, Fairlight’s investment portfolios are rooted in the super efficiency of the Global Market Portfolio and built with low-cost, index-based funds and ETFs. ![]() In fact, there is a very good chance that the railroad stock prices will rise, as passengers look for alternative modes of transportation.We started our investment careers in the early days of index and ETF investing when market values and available index products were a fraction of what they are today. You can counterbalance these stocks with a few railway stocks, so only part of your portfolio will be affected. This means your portfolio will experience a noticeable drop in value. Share prices of all those stocks potentially will drop in tandem after industry-specific bad news, such as an indefinite pilots strike that will ultimately cancel flights. Let's say you have an investment portfolio that only contains airline stocks. Understanding Diversification in Investing A diversified portfolio may lead to better opportunities, enjoyment in researching new assets, and higher risk-adjusted returns.Balancing a diversified portfolio may be complicated and expensive, and it may come with lower rewards because the risk is mitigated.Investors can choose to pick their own assets to invest in otherwise, they can select an index fund that comprises a variety of companies and holdings.Unsystematic risk can be mitigated through diversification, while systematic or market risk is generally unavoidable.Diversification reduces risk by investing in vehicles that span different financial instruments, industries, and other categories. ![]()

Although it’s a car, it isn’t out of place among the Museum’s historic air- and spacecraft. Today, a lunar rover test vehicle-almost identical to the vehicles that went to the moon on three Apollo flights-is parked in the National Air and Space Museum. ![]() The “moon buggy” enabled astronauts to explore more of the moon’s surface during their mission, Scott and Irwin traveled 17 miles, far more than previous astronauts, who were limited to short walks around their landing sites. The agency expects to make an award for that lander in June 2023.The first off-world road trip took place on July 31, 1971, when Apollo 15 astronauts David Scott and James Irwin jumped into their Lunar Roving Vehicle and took off across the moon’s surface at a blistering 2 mph. NASA is currently soliciting proposals for the second Artemis lander, with a Dec. He said NASA was closely following that upcoming test flight as one of the milestones in the development of the lunar lander version of Starship. That schedule depended on both testing of the vehicle as well as receipt of a launch license from the Federal Aviation Administration. 31 meeting of the NASA Advisory Council’s Human Exploration and Operations Committee, Mark Kirasich, deputy associate administrator for Artemis Campaign Development at NASA, said the first Starship orbital launch attempt could take place as soon as early December. Elon Musk, chief executive of SpaceX, tweeted afterwards that the company would follow the test with a 20-second engine test, “possibly one more static fire, then orbital launch attempt.”Īt an Oct. 14 static-fire test, SpaceX fired 14 of 33 Raptor engines in the vehicle’s Super Heavy booster, the most ignited in a single test. SpaceX is continuing preparations for a first orbital launch attempt of Starship at its Boca Chica, Texas, test site. The lander selected for development under SLD would fly its demonstration mission no earlier than Artemis 5. However, agency officials said last month that the Option B mission would be Artemis 4, a mission that NASA previously planned to devote to work on the lunar Gateway and not include a landing. When NASA announced its intent to exercise Option B, it was not clear when that second mission would fly. ![]() SpaceX could not compete for the SLD award, but NASA said it would instead exercise the option in SpaceX’s original HLS award to upgrade Starship for later Artemis missions that will carry more astronauts and remain on the moon for longer periods. NASA announced its intent to exercise Option B in March when it unveiled its Sustaining Lunar Development (SLD) effort to fund development of a second Artemis crewed lunar lander. “This critical work will help us focus on the development of sustainable, service-based lunar landers anchored to NASA’s requirements for regularly recurring missions to the lunar surface.” “Continuing our collaborative efforts with SpaceX through Option B furthers our resilient plans for regular crewed transportation to the lunar surface and establishing a long-term human presence under Artemis,” Lisa Watson-Morgan, NASA HLS program manager, said in a statement. ![]() The option also includes a second crewed demonstration landing mission. Option B covers upgrades to the Starship lander originally selected for HLS by NASA in April 2021 for $2.9 billion. 15 it completed a contract modification for what is formally known as Option B of its Human Landing System (HLS) contract with SpaceX. NASA has awarded SpaceX a $1.15 billion contract to develop an upgraded version of its Starship lunar lander and fly a second crewed mission. ![]() ![]() Any modifications of drawings, prototypes and other work of Seller after approval by Buyer will be at Buyer's expense at Seller's normal rates for services and materials.

We also grow a yellow flowering form we call Aloe camperi 'Yellow' and there is a more robust form that flowers earlier (March) that has long been grown at the Huntington Botanic Garden (HBG#92) and was distributed as an International Succulent Introduction as Aloe camperi 'Cornuta' (ISI -2005-15). The late spring flowering of this plant distinguishes it from many other species that tend to bloom winter into spring or later in the fall. This great landscape plant is very showy in full bloom and has been in cultivation in California for many years under the name Aloe eru. Hardy to mid 20's F - no damage observed on our plants at 25° F in the January 2007 cold spell but plants were noted as damaged at temperatures in the low 20's by Brian Kemble at the Ruth Bancroft Garden in Walnut Grove.

Or, a modification can be as complex as re-designing specific characters to accommodate the newsprint you use and how the letters look on the pages. If you work for the Daily Bugle, and want to make sure your designers are always going to use the right version of Times New Roman for body text, you could modify the name of the font to say, “Daily Bugle Times New Roman.” This can make it easier to find in a font menu. He said the study brought up two significant issues in his mind: “That of all the thousands and thousands of typefaces out there, that certain typefaces have intended uses or work better, and certain ones work best for newspapers.” And second, that type has demanding challenges to perform.ĭavis was also surprised at the wide use of custom typefaces or modifications made to fonts to make them fit the look and feel of the newspaper.Ĭustomizing a typeface could involve something as simple as putting your newspaper’s name in front of the typeface you use most often. “When you move publications to the Web it’s a whole different paradigm.” “One of the things I wanted to do is find out what newspapers use for fonts in their print editions,” he said. And, it could mean that newspapers need to figure out whether they are using custom fonts and what that means for their Web-based publications.īill Davis, the study’s author, says he hopes the report will stimulate discussions about typeface usage in print and online at newspapers. But then the paper has to figure out how to better transport fonts in PDFs and other files. ![]() What does this typeface study mean for readers, designers, and publishers? It could mean better on-screen reading of newspaper Web sites, if different typefaces are designed specifically for electronic editions. First, if a newspaper uses “off the shelf” fonts what are the restrictions that would prevent them from being used for electronic editions? Are there copyright restrictions or licensing issues? And, if a newspaper has fonts designed specifically to use on newsprint how can the paper use those fonts electronically? Fonts for the newspaper can be embedded with the PDF, or the newspaper can use fonts that are close approximations of the newsprint fonts.Įlectronic editions of newspapers raises many questions. Some newspapers have links on their Web sites to the printed pages in a PDF format exactly as they were printed that day. The Font Bureau, a Boston-based type foundry, provided typeface information for 12 of those 15 newspapers.Īscender said it could not determine fonts for three newspapers. Fifteen newspapers were either not posted on Newseum’s site, or didn’t have embedded font information. Using the “ Today’s Front Pages” section, Ascender examined 85 newspapers that embed their font information with the PDF file. The study was conducted by examining PDF versions of newspapers that are posted on Newseum’s Web site. According to the study, the 10 most popular typeface families (in order) are: Poynter (36 newspapers), Helvetica (28), Franklin Gothic (27), Times (20), Utopia (12), Nimrod (9), Century Old Style (8), Interstate (8), Bureau Grotesque (7), and Miller (7). Thirty-five out of the 97 newspapers studied use a custom-designed typeface in addition to fonts that can be purchased “off the shelf.”Īn analysis of the typefaces used by nearly 100 leading newspapers shows that 10 fonts have emerged as industry leaders. 22, also found that many of the typefaces were designed specifically for the newspapers. The study, conducted by Ascender Corporation from Sept. 9, 2004 found that newspapers use only a few typefaces even though there are many more available for newspaper design.

For the actinide elements Ac-Es ( Z =89-99), we were able to rely almost entirely on the very complete compilation by Blaise and Wyart. No complete and critical compilations of energy levels have appeared for most of these spectra since vols. 2 and 3 of Atomic Energy Levels. For example, the current version of the ASD includes energy-level data for only two spectra (Mo I,II) of the 72 spectra of the neutral and singly-ionized atoms of the elements Rb to Ba ( Z = 37-56) and Hf to Ra ( Z = 72-88). Although the data are incomplete, our wavelength and energy level tables for these elements, especially, comprise a supplement to the ASD. ![]() Our most extensive use of data from the original literature has been for the heavier elements. In addition to more extensive data for many of the spectra in this Handbook, the ASD has data for higher ionization stages of many elements and includes the references.Īlthough we have made heavy use of previous compilations, our tables for the great majority of elements include at least some data compiled by us from more recent original literature and, in some cases, from unpublished material. The data from most of the NIST compilations we have used are available online from the Atomic Spectra Database (ASD see ). More complete data than those selected for this Handbook can usually be found in references given with the tables for particular spectra. We also give a separate table of energy level data for each spectrum which, although incomplete, includes levels additional to those involved in the persistent-line transitions. In addition to the wavelengths and intensities, the energy levels and transition probabilities (where available) are listed for a total of about 2,400 lines in these tables. More complete data for a smaller number of the most persistent lines of each spectrum are given in additional tables for each element. The wavelengths, intensities, and spectrum assignments are given in a table for each element, and the data for the approximately 12,000 lines of all elements are also collected into a single table, sorted by wavelength (a "finding list"). The compilation includes data for the neutral and singly-ionized atoms of all elements hydrogen through einsteinium ( Z = 1-99). This handbook is designed to provide a selection of the most important and frequently used atomic spectroscopic data in an easily accessible format.
