Broadband

first_img Comments are closed. Cribsheet:The latest technology in a nutshell. This week: Broadband.Whatis it? Thename used to describe various types of high-speed connections to the Internet.Broadband is viewed in many quarters as the key to the e-economy. Thetwo big constraining factors of Internet usage, especially at home, is speedand cost – broadband potentially gets rid of both restraints. Oneof the most talked about broadband offerings of the moment is ADSL (asymmetricdigital subscriber line) and works across existing copper telephone wires.This, potentially, works at 10 times faster than a standard modem connectionand offers an always-on link to the Internet for which users pay a flat-rateaccess fee rather than call charges each time they dial up their Internetservice provider. Otherforms of broadband include cable modems, leased lines and satellite.Whatdoes it mean to me? Ifyou’re accessing the Internet via your office network, speed is probably not anissue at the moment. However,broadband will have an increasingly important part to play in the developmentof mobile or home-working and also in the field of e-learning. Ifyou access the Internet at home, you will have noticed how much slower it iscompared to across your network at work. ADSL, for instance, can work at up to10 times as fast as a conventional modem (upwards of 512kbps whereas aconventional modem is around 56kbps).Broadbandaccess at home will not only enable workers to carry out any Internet-basedwork far more quickly, it will also let them maximise technologies that currentlystruggle across standard home modems, such as video-conferencing andwebcasting. Itwill also enable the HR department to control the cost of a workers’ Internetaccess at home, since they will be paying a flat rate for the service. Thismeans you can also be fairly relaxed about them using it for leisure activitiessince it won’t cost any more. BT’s domestic ADSL service is £39.99 a month plus£150 set-up fee.Manye-learning courses rely on users being able to download large amounts of data,such as multimedia and video files as part of the course, and broadband alsomakes this a much more viable option from home.Wheredo I go for further information? Ifyou want to further investigate a broadband solution for members of yourworkforce, there are a number of educational sites. Among the best are www.broadband-news.co.uk   www.broadband-help.co.uk   and www.cable-modems.co.uk. BT’sservice at www.btopenworld.com details BT’s ADSL service and Demon Internet’sequivalent can be found at www.demon.net/products/access/adsl-launch.shtml.Nokiais developing a range of wireless broadband solutions aimed at the mobilemarket.

Work issues put at heart of government

first_imgWork issues put at heart of governmentOn 19 Jun 2001 in Personnel Today Previous Article Next Article Therestructuring of Whitehall has placed workplace issues at the centre ofgovernment, claims the CIPD. JohnPhilpott, the institute’s chief economist, explained that the reformed departmentsare better equipped to deliver the Government’s objectives of increasedemployment, improved work quality and higher productivity levels.Themerger of the employment service with the Department of Social Security tocreate a new Department for Work and Pensions will lead to a greater focus onemployment policy.Philpottsaid, “This has completely demolished the old-fashioned concept of socialsecurity and is much more work focused.”Thetransfer of the employment division from the old DfEE is also good news for theHR profession, claims Philpott.Hesaid, “There was a tendency before for the skills agenda to get mixed upwith Welfare for Work agenda. But the creation of a Department of Work andPensions means there will be more scope for workforce development.”Healso welcomed Patricia Hewitt’s appointment as Trade and Industry Secretary andMinister for Women. “Thisis a politically shrewd move. It will provide an opportunity for linkingwork-life balance issues with issues of productivity,” he said.TheDTI has taken on equal opportunities and pay issues as well as work-lifebalance from the Department for Education and Skills.Theshape of key government departments Departmentof Trade and Industry:Secretaryof state: Patricia HewittFocus: Trade, inward investment, equal opportunities, pay, work-life balanceDepartmentof Work and Pensions:Secretaryof state: Alistair DarlingFocus: Employment, with its transfer from DfEEDepartmentfor Education and Skills:Secretaryof state: Estelle MorrisFocus: Raising standards in education in secondary schools and by getting morestudents into higher educationHomeOffice: Secretaryof state: David BlunkettFocus: Tackling crime, reform of criminal justice system and asylum Comments are closed.

CoStar revenue soars 19% after year of acquisitions

first_img Share on FacebookShare on TwitterShare on LinkedinShare via Email Share via Shortlink CoStar Group Andrew C. Florance. (Getty) CoStar Group’s revenue soared to $1.66 billion in 2020, as the pandemic pushed more people to shop for real estate online, the company reported Tuesday.While earnings rose 19 percent, the real estate data giant’s profits sunk thanks to the coronavirus closures in the spring. Net income plunged nearly 28 percent to $227 million for the full year. CoStar reported net income of $314.9 million in 2019.Still, CoStar turned in a strong second half of the year as the real estate market rebounded. It notched $100 million in sales bookings during the latter part of 2020, including $49 million in net new sales during the fourth quarter.Read moreCoStar offers $6.9B to buy CoreLogic Why CoStar paid $250M for Homesnap CoStar fights RentPath over $60M break-up fee Email Address* Andy FlorancecorelogicCoStarreal estate datazillow Full Name* Last year, CoStar acquired Ten-X, Emporis and Homesnap, although its deal to buy RentPath fell through after the Federal Trade Commission objected.With $2.7 billion in debt and equity on its books, CoStar said it would double down on acquisitions in the coming year, particularly in the residential space.Earlier this month, CoStar submitted a bid to buy CoreLogic for $6.9 billion, or 20 percent higher than CoreLogic’s previously-accepted offer from Stone Point Capital and Insight Partners. “This combination would triple CoStar Group’s total addressable market,” CEO Andy Florance wrote in a letter to CoreLogic’s board.During an earnings call, Florance said there is “vast potential” to integrate commercial and real estate data tools.CoStar said Apartments.com notched record results last year, with revenue of nearly $600 million, up 22 percent year-over-year. “We believe that our increased investment in marketing for Apartments.com in 2020 was a key driver in our performance and produced outstanding results,” Florance said in a statement. Apartments.com notched 170 million virtual tours in 2020, twice as many as 2019.LoopNet also had a strong year with 20 percent year-over-year revenue growth.CoStar projected revenue this year between $1.925 billion and $1.945 billion.

Plasma metabolites in macaroni penguins (Eudyptes chrysolophus) arriving on land for breeding and moulting

first_img1. Plasma metabolites and nutrients of macaroni penguins (Eudyptes chrysolophus) arriving on land in good condition, following intense feeding, for breeding and moulting were investigated. 2. The pre-breeding female birds had significantly higher concentrations of total lipid, iron, magnesium, calcium, inorganic phosphate and alkaline phosphatase, and lower concentrations of total cholesterol, all-trans retinol (vitamin A) than the pre-breeding males. 3. With the exception of iron, which was lower in the male, the various parameters measured in male and female pre-moult penguins did not differ. 4. Some of the plasma metabolite concentrations of the pre-moult birds differed substantially from those of their male and female pre-breeding counterparts. 5. The observed differences were thought to be the result of mobilization in response to physiological demands for egg formation and moulting. 6. However, it is possible that discrepancies were partly due to selective ingestion of nutrients in preparation for higher physiological demandslast_img read more

Cyclotron absorption of ion-cyclotron waves at the bi-ion frequency

first_imgWe demonstrate that geomagnetically trapped ion-cyclotron waves that are generated near the equator with frequencies below ΩHe+, can experience significant O+ cyclotron resonant absorption near the reflection point at frequencies just above the bi-ion frequency. The absorption is strongest when the wave normal angle is highly oblique and when the heavy ions are relatively hot (T > 1 keV) with a concentration of no more than 1 or 2%. This suggests that wave absorption near the bi-ion frequency could contribute to the heating process for energetic ring current O+; in the outer radiation zone during geomagnetic storms.last_img

Pillow metabasalts in a mid-Tertiary extensional basin adjacent to the Liquiñe-Ofqui fault zone: the Isla Magdalena area, Aysén, Chile

first_imgPillow metabasalts and interbedded slates adjacent to the Liquiñe-Ofqui fault zone (LOFZ) of the southern Chilean Andes have been studied using electron-microprobe mineral analysis, major and trace element whole-rock geochemistry and RbSr geochronology. The rocks show previously unrecognized mineralogical evidence of two metamorphic events in a low-pressure environment: an early greenschist-facies metamorphism, possibly during emplacement on the sea-floor, and a patchy amphibolite-facies overprint, which could represent either continuing sea-floor metamorphism or contact metamorphism associated with Miocene plutons. The meta-igneous rocks are considered to have formed from mid-Tertiary basaltic magmas with mixed within-plate/volcanic arc characteristics as seen in present-day volcanoes in the area, but enriched in immobile elements such as Ti, Zr, And Y. They were probably emplaced between 45 and 20 Ma, into a contemporaneous marine pull-apart or extensional basin with thin continental or oceanic floor. Many of the petrological and geochemical features of an ophiolite suite may be recognized in the immediate area.A chain of such basins developed immediately west of the LOFZ strike slip system, probably during an Eocene- Early Miocene period of oblique subduction-convergence in southern Chile, and closed when the approach angle became more orthogonal 25 Ma. Magmatic arc plutonism was resumed at about 20 Ma and continued into the latest Cenozoic.last_img read more

Temporal properties of magnetospheric line radiation

first_imgMagnetospheric line radiation (MLR) events are relatively narrowband VLF signals that sometimes drift in frequency and have been observed in both ground-based and satellite data sets. We present the results of a survey undertaken on the basis of measurements made of MLR events observed at Halley, Antarctica (75°30′S, 26°54′W, L ≈ 4.3), in June, July, September, and December 1995, specifically looking at the temporal properties of Halley MLR events. We find that (1) single MLR lines described in previous papers tend to be comprised of up to 3 lines with widths of 5–10 Hz. (2) The multiple lines show highly variable spacings (e.g., 6), which affects only 8% of the total MLR events in this study. For smaller storms, there is little effect, although MLR events tend not to occur when the geomagnetic activity has been quiet in the previous 48 hours. (7) There is no dependence of MLR occurrence rates upon the instantaneous levels of geomagnetic activity. (8) The average duration of a typical MLR event at Halley is ∼ 30 min, quite similar to previous reports.last_img read more

Measurements of NOx emissions from the Antarctic snowpack

first_imgIt has been shown that NOx is produced photochemically within the snowpack of polar regions. If emitted to the atmosphere, this process could be a major source of NOx in remote snowcovered regions. We report here on measurements made at the German Antarctic station, Neumayer, during austral summer 1999, aimed at detecting and quantifying emissions of NOx from the surface snow. Gradients of NOx measured, and fluxes calculated using local meteorology measurements. On the 2 days of flux measurements, the derived fluxes showed continual release from the snow surface, varying between ∼0 and 3 × 108 molecs/cm²/s. When not subject to turbulence, the variation was coincident with the uv diurnal cycle, suggesting rapid release once photochemically produced. Scaling the diurnal average of Feb. 7th (1.3 × 108 molecs/cm²/s) suggests an annual emission over Antarctica of the order 0.0076TgN.last_img read more

Albatross populations in peril? A population trajectory for black-browed albatrosses at South Georgia

first_imgSimulation modeling was used to reconstruct Black-browed Albatross (Diomedea melanophris) population trends. Close approximations to observed data were accomplished by annually varying survival rates, reproductive success, and probabilities of returning to breed given success in previous years. The temporal shift in annual values coincided with the start of longline fishing at South Georgia and potential changes in krill abundance. We used 23 years of demographic data from long-term studies of a breeding colony of this species at Bird Island, South Georgia, to validate our model. When we used annual parameter estimates for survival, reproductive success, and probabilities of returning to breed given success in previous years, our model trajectory closely followed the observed changes in breeding population size over time. Population growth rate was below replacement (lambda < 1) in most years and was most sensitive to changes in adult survival. This supports the recent IUCN uplisting of this species from “Vulnerable” to “Endangered.” Comparison of pre-1988 and post-1988 demography (before and after the inception of a longline fishery in the breeding area) reveals a decrease in lambda from 0.963 to 0.910. A life table response experiment (LTRE) showed that this decline in lambda was caused mostly by declines in survival of adults. If 1988–1998 demographic rates are maintained, the model predicts a 98% chance of a population of fewer than 25 pairs within 78 years. For this population to recover to a status under which it could be “delisted,” a 10% increase in survival of all age classes would be needed.last_img read more
