Throughout its travels, Space Exploration Technologies Corporation's (SpaceX) Falcon 9 rocket and Dragon cargo craft carried more than cargo to and from space station. The flight also carried the aspirations of a new generation of aerospace companies hoping to expand humanity's access to space.

In many ways, the ambitious mission ? though just a demonstration ? represented a high-profile test of NASA's new direction. The agency in effect is turning over the keys to low-Earth orbit to the private sector. Under Geroge W. Bush, NASA moved in that direction for cargo. Under President Obama, it has expanded the goal to include humans as well.

In each case, NASA is to become a paying customer for transportation services to and from the space station rather than acting as owner and operator of the spacecraft. Meanwhile, the agency is turning its human-spaceflight attention to sending astronauts beyond low-Earth orbit.

The move has been greeted with a great deal of skepticism among some in Congress as well as the space-advocacy community.

But even before Dragon splashed down, the mission's success garnered one new convert.

In an opinion column that appeared May 27 in the Orlando Sentinel, former astronaut and space shuttle commander Mark Kelly noted his initial resistance to the Obama administration's cancellation of NASA's Constellation program, which aimed to replace the shuttle with two rockets ? one for crews and light cargo duties, the other for heavy lifting and travel beyond low-Earth Orbit.

?I worried about what it would mean for NASA's overall mission, and what it would do to the brilliant and patriotic men and women who work there,? Mr. Kelly wrote. ?But I'm impressed with how far SpaceX has come in 17 months.... The president made a tough, bold decision ? and I now believe he was right.?

For now, SpaceX and NASA are savoring the success.

Dragon left the station shortly before 6 a.m. Eastern Daylight Time after station flight engineers Joe Acaba and Don Petitt used the space station's robotic arm to detach Dragon and gingerly position it about 30 feet below the orbiting outpost. At 10:51, it fired its motors in a ?deorbit burn? designed to slow the craft by about 200 miles an hour ? enough for gravity to exert a stronger tug to begin the craft's descent.

Why Routine Eye Exams are the Key to Better Vision and Self ...

Routine eye exams are a crucial part of healthy lifestyle. Yet they are ignored most of the time. It is ironic that most people regularly visit their doctors and dentists for checkups, yet they seldom visit their eye specialist. This widespread habit leads to annual expenditure of billions of dollars in complex surgical procedures and medications. These billions of dollars can be saved if people develop the habit of taking routine eye exams on a regular basis.
Eye Exam

Different Types of Tests

Eye Chart Test

This requires a person to read a chart, first with both eyes, and then with one eye covered. It is a simple examination designed to evaluate visual acuity.

Retinoscopy test

The patient is asked to focus the eyes on a target in a dimly lit room, after which the doctor will shine a light into the eyes to see how the light bounces.

Who Conducts an Eye Exam?

A routine eye exam consists of different parts. A simple eye examination is performed to see if you have weak eyesight or not, such as nearsightedness or farsightedness. Such tests are carried by optometrists. An optometrist is not an eye specialist and is only qualified to detect weak eyesight and recommend prescriptions for eye drops, spectacles and contact lens like the?focus dailies all day comfort.

Such eye examinations are cheap and you can even find an optometrist in major shopping malls. You can have your eye tested without prior appointments, after which you can obtain glasses or?the focus dailies all day comfort?lens on the spot.

A more complete and accurate examination will not involve the calculation of eyesight, but it would probe other vision problems that you may possibly have. This test is conducted by a highly qualified and experienced doctor known as an ophthalmologist. Such examinations are more thorough than the one mentioned above and are crucial for the health of your eyes. ?A ophthalmologist will be able to detect disorders like:

  • Glaucoma
  • Presbyopia
  • Astigmatism
  • Dry eye Syndrome
  • He/she will also provide the relevant treatment and medication for the diseases that are diagnosed. Many eye problems are also early signs of chronic diseases like stroke and diabetes.

    Some of these symptoms include:

  • Blurry or double vision
  • Seeing spots before the eyes
  • Irritation in the eyes
  • Frequent eye exams can help to discover these problems in their early stages so they can be effectively countered before taking root.

    People who want to use contact lens need to take a contact lens exam. This should not be confused by a routine eye exam. During this test, the surface of the cornea will be examined to make that the lens fit perfectly. ?A kerameter is used to measure the curves of the cornea, and in addition, the pupil and the iris will also be examined. The prescription of the lens will also depend on the lifestyle of the patient.

    Why Most People do not take Eye Exams Seriously?

    The reason why many people ignore eye care is due to the costs involved. Visiting an eye doctor can prove to be expensive. Moreover, most insurance plans do not cover regular eye exams and treatments adequately. ?This further hinders people from getting their eyes checked on time. However, since eye exams are of immense importance, you are advised to get an eye insurance plan alongside your health cover. ?It may not give you the savings that you hope for, but it will provide great savings in the long run.??

    What is the Suitable Age for Eye Examination?

    Routine eye exams, especially conducted by an ophthalmologist rather an optometrist, are necessary for any effective health plan. It does not matter what your age is. Everyone should give eye examination a top priority in their lives. Elder people, who suffer from eye problems more than the young generation should make an extra effort to have routine checkups done on time.

    Even among the children and young people, eye problems are increasing at an alarming rate, mostly due to the increasing usage of computers and other related gadgets. ?This proves that no matter what the age, at least 2 visits to the eye doctor throughout the year are extremely important.

    Keith Dromm on Sexual Harassment | Broadview Press Publisher's ...

    Keith Dromm, Associate Professor of Philosophy at Louisiana Scholars? College at Northwestern University and author of the recently published Sexual Harassment: An Introduction to the Conceptual and Ethical Issues, sat down with Alex Sager, Acquiring Editor for the Broadview Guides to Business and Professional Ethics series, to answer a few questions on the corporate, legal, and philosophical issues surrounding sexual harassment.

    Interview with Keith Dromm:

    1. The title of your book is Sexual Harassment: An Introduction to the Conceptual and Ethical Issues. What makes sexual harassment a conceptual issue?

    Before we can try to prevent sexual harassment we need to understand what it is. For example, without a good understanding, we might try to prevent actions that are not sexual harassment?or even illegal or wrong in some other way?or fail to prevent actions that are sexual harassment. Unfortunately, a single, stable definition of sexual harassment is elusive. Part of the challenge of defining sexual harassment occurs because there are three different sources of definitions: legal, descriptive, and normative.

    The legal understanding of sexual harassment arises from a number of lawsuits in the 1970s. It was during this period that a single term emerged for describing the various behaviors that constitute it and that they became illegal. As I discuss below, in the United States this litigation led to an understanding of sexual harassment based on anti-discrimination law.

    Descriptive definitions simply record how the term is typically used in society. Though they are influenced by law, they often differ from legal definitions in important respects. For example, many people would consider it sexual harassment to yell sexually suggestive comments to passing strangers even if it might not legally constitute sexual harassment.

    Both legal and descriptive definitions might ignore some actions that ought to constitute sexual harassment. We thus need a normative definition of sexual harassment that tells us what is wrong about it. Normative definitions may then be used to criticize legal and descriptive definitions. Since moral theorists disagree about the nature of sexual harassment, one of my goals in the book is to argue for a ?core? definition that contains the common and essential elements of different legal, descriptive, and normative definitions. According to this definition, sexual harassment is unwelcome behavior of a sexual nature, and the persons responsible for this behavior have power over its target.

    A definition of sexual harassment can allow us to answer other important conceptual questions related to sexual harassment, such as those that serve as the titles to two of the book?s other chapters, ?Where can sexual harassment occur?? and ?How can sexual harassment occur?? These chapters examine, respectively, the contexts in which sexual harassment can take place and the behaviors, sometimes subtle or in other ways difficult to recognize, that can constitute sexual harassment. Only a good grasp of the concept of sexual harassment can allow us to answer these and similar questions.

    2. You are critical of sexual harassment law, particularly in the United States where it is considered to be an issue of sex discrimination. In your view, is discrimination the primary issue in sexual harassment? What alternative legal frameworks exist? What recommendations would you have to a country that is drafting new sexual harassment legislation?

    Sexual harassment law in the United States arises out of anti-discrimination law; there is no federal law that specifically targets the behaviors that constitute sexual harassment. The law reflects the recognition that sexual harassment can be used as a tool of discrimination, one that has been wielded primarily against women to limit their opportunities in employment and education. One problem, however, is that not all cases of sexual harassment are cases of discrimination. The most notorious example is the so-called ?equal-opportunity harasser,? someone who harasses men and women equally, so doesn?t discriminate in his or her harassment. The victims of these forms of sexual harassment are harmed, but not because they are discriminated against. There is harm, for one thing, to their dignity. But there is little legal protection against such harms.

    It is important to recognize, both conceptually and legally, how sexual harassment can be a form of discrimination. However, workers have the right to be protected from other forms of sexual harassment. I discuss in my book various alternative legal approaches but do not come out strongly in favor of any one of them. They all involve separating sexual harassment law from anti-discrimination law, although without necessarily abandoning the latter. We still need laws to protect us from discrimination. Protection from other forms of sexual harassment might not need new laws directed specifically at them. Laws that grant greater overall protection to workers might be sufficient. For example, in the United States, the employment relationship is governed by the at-will doctrine, which allows employees to be fired without just cause. I endorse the view of many legal scholars and others that the at-will doctrine weakens the power of workers, including making them less able to resist sexual harassment. Abandoning or relaxing the doctrine would grant greater protection to workers against all forms of harassment.

    It is also important to recognize that the law is not an effective or otherwise appropriate remedy for all forms of sexual harassment. It also cannot provide a complete solution to sexual harassment. Sexual harassment is caused by beliefs about the worth and dignity of individuals and groups of people that cannot be modified by the law alone. Deeper cultural changes are required to change these beliefs. One of these changes, of course, is affording equal opportunities to women in our workplaces and schools by eliminating discrimination.

    3. You state in your introduction that many employees resent sexual harassment training and that it is often poorly implemented. What thoughts do you have on how to make sexual harassment training more effective?

    I?d like to see some research that attempts to explain the negative attitude employees have towards sexual harassment training, but I suspect that many simply find it insulting. Training of any sort implies some sort of deficiency, but there are some deficiencies we?re more willing to admit to than others. If a company implements new software or machinery, most employees would willingly admit their ignorance about it and gladly accept training to help them use it. Training in sexual harassment, however, implies that a person?s social skills need to be improved. Most people are reluctant to admit to this and would understandably resist training on how to behave better towards others (even though many of these people might need this sort of training). More effective training would attempt to deemphasize, if not eliminate, this implication. One way to do this would be to make the training interactive. Rather than being ?lectured to? by speakers or videos about how to treat others, the training could involve soliciting from employees their ideas about how to reduce sexual harassment in the workplace. It would draw on the employees? own expertise on how to treat others, rather than presupposing that they need some training in this. Some of the ideas generated in these sessions could even be incorporated into the workplace?s sexual harassment policy. Research has shown that interactive training is more likely to change positively the behavior and attitudes of trainees. It can also improve employees? attitudes towards training by getting rid of the implication that their interpersonal skills need to be improved. To go along with this, it would probably be helpful if the word ?training? were dropped and replaced with something like ?workshop.?

    There are other problems with sexual harassment training. For example, many workplaces institute training in order to comply with state laws or as a protection against lawsuits. Research has shown that when these are its only motivations, the training tends to be less effective in reducing incidences of sexual harassment. So, the training should be guided by a sincere concern to reduce sexual harassment. I discuss more ideas for improving sexual harassment training in the final chapter of my book, ?How to Prevent Sexual Harassment.?

    4. Vicki Schultz has argued that sexual harassment policies often lead to a ?sanitized workplace? in which employers prohibit sexuality in the workplace even if it is benign or positive. Do you share Schultz?s concern and do you think there are ways of implementing sexual harassment policies that avoid her objections?

    Schultz believes that sexual harassment law could be used by employers as an excuse to more tightly control employees? behavior. She is concerned particularly about prohibitions on romantic or sexual relationships between employees or the use of so-called ?love contracts? that require workers to acknowledge their consent before entering such relationships. While the ostensible goal of such policies is the prevention of sexual harassment, they inhibit the development of both sexual and non-sexual consensual relationships between employees. Given the amount of time that employees spend at work, the workplace is for many of them a primary source of social relationships. So, these policies will have deleterious consequences on their social lives. These are legitimate concerns. Schultz correctly observes that it impossible to eradicate sexuality entirely from the workplace and the result of policies that control employees? interpersonal relationships will only be increased surveillance of workers? behavior. The workers might also develop a negative attitude generally towards efforts to combat sexual harassment because of policies like these. Nevertheless, there remains a need for sexual harassment policies in workplaces. When properly designed, they can protect both employers and employees. The policies need to be targeted towards the behaviors that can constitute sexual harassment and the relationships in which it can occur. Policies that prohibit or tightly regulate all sexual or romantic relationships in a workplace are overkill and will have those negative consequences about which Schultz warns.

    5. Much of your teaching and writing explores topics in popular culture?in fact, your earlier published work on sexual harassment appeared in The Office and Philosophy. You?ve also contributed articles to a number of collections on philosophy and popular topics such as the television show The X-Files, the film Inception, and the films of Steven Spielberg. What led you to regularly contribute to books aimed at the general reader?

    Philosophy books aimed at the general reader are valuable. They can introduce a wider audience to philosophy than more academic books, which is important since there are decreasing opportunities to study philosophy in schools. Such books are also capable of demonstrating the relevance of philosophy. They can show that philosophy has something to say even about, for example, popular culture, as well as the problems?sometimes fantastical, but also often ordinary?that are the subjects of popular culture (my book includes an appendix of popular films and television shows that deal with sexual harassment).

    I have the same aspirations for my book. It is written for a general audience. But like the books I?ve contributed to, its purpose is not to instruct readers about philosophy. Instead, it uses philosophy to help clarify and in other ways illuminate its topic. It hopefully demonstrates how philosophy can be used to increase our understanding of sexual harassment, and how this understanding is essential to our efforts to reduce it.

    Flavors.me


    Among the many options you have for creating a personal Web page, also known as a landing page, Flavors.me (Free, or $20 with extra options) stands out at the best choice today. When it comes down to the basics, Flavors.me is like most of its competition?it's there to facilitate a landing page with a big beautiful background image and links to go with?but it has more options to go along with the simplicity, so you can get as complicated as you want as you build your online destination. Plus, even if you pay, it won't hurt your wallet too badly.

    Flavors.me comes in two flavors. The free version offers seven layouts and gathers content from up to five services. That's more than enough for most. However, a paid version for $20 a year includes 17 layouts, 222 font choices, links to unlimited service, domain-name support, real-time traffic stats, and several more features. Once you've created an account, you can log in using a Facebook, Google, or Yahoo account (whatever is linked to your landing page).

    Customization
    You're not stuck with just the look Flavors.me provides since you can customize any of the layouts. Designing the page is a simple matter of accessing the Design drop down menu while you're on your Flavors.me account. A change in layout or font is instantly reflected on the site for you to accept or reject. However, it's hit or miss as to how well the layouts and fonts work with your graphics. Trial and error and patience may be required to get it just right. Click the "Community" link and you'll get a page with lots of examples you can emulate.

    Promotion
    Naturally, you can link your personal Webpage just about any service on the Web?including Facebook profiles, Facebook Pages, Twitter, Blogger, Wordpress, Typepad, Posterous, Netflix, Vimeo, YouTube, Flickr, Digg, Etsy, Foursquare, and others?because that's the whole point. Drop in an RSS feed, too. If Flavors.me doesn't automate the link, you can create your own, getting a generic icon to go with it. There's even support for map links, which display a zoom-able Google map.

    Extras
    The extra options you get with the paid version are so varied that you probably won't need them all, but at only $20 a year, they're worth at least a try (and you get your money back if you cancel within 90 days). You can pay via Google, PayPal, or Amazon accounts. The extras include real-time stats, a contact form, a mobile version of your site for smartphone access, a customizable favicon to show up in browser address bars, and, perhaps best of all, a custom domain name that points to your page, which is included in the cost. You can also go with a domain you already have registered, or the flavors.me/username address provided automatically for all accounts. A Flavors.me landing page looks pretty good on a smartphone, too. When you pay, all of these options show up in the Design menu.

    Free and paid accounts get access to the "social stream" feature, which is like an RSS reader for all the social goings-on of your friends. It's one of those features you probably don't need and probably won't use, but it's at your disposal. And one other nice extra: if you're totally sick of having a Flavors.me page, they let you delete the whole account.

    Small businesses may want to consider Sidengo instead, but individuals will appreciate what's available with Flavors.me. It stays ahead of the more immediate completion from AOL's About.me with the extras it offers. Flavors.me is a fantastic, easy-to-master option for creating an affordable and great looking personal landing page, with or without paying for it. Flavors.me is our Editors Choice for personal Web page creation.

    Ultra Electronics, TCS announces High-Capacity Radio (HCR) with ...

    CANSEC, Ottawa, May 30, 2012 /PRNewswire/ - Ultra Electronics, TCS, based in Montreal, Canada, has announced a new version of the Ultra High-Capacity Radio (HCR) now capable of 400 Mbps of bandwidth throughput. The HCR is a small form-factor and highly ruggedized tactical radio that delivers high bandwidth throughput over long distances using point-to-point microwave wireless technology. The radio's dramatic increase in bandwidth capability over previous generation radios is expected to accelerate the adoption of handheld devices and next-generation applications at the tactical edge, a key trend within many militaries around the world. The new radio's much smaller form factor requires fewer assets to deploy and less logistical support than previous generation HCLOS radios, providing users with secure voice, data, video and sensor backhaul communications in difficult,? hard to reach, operating environments.

    The HCR incorporates and improves on the best features of Ultra's battle-proven AN/GRC-245 and AN/GRC-512 radios to form a new platform that can perform multiple roles.? The single box mast mount radio supports the roles of a High-Capacity Line-of-Sight (HCLOS) radio relay, including spectrum efficiency and long range waveforms, as well as a true full-band Electronic Counter Counter Measure (ECCM) radio relay. Therefore, it effectively provides two radio types in a single common platform, enabling each relay vehicle to quickly mix and match each mode to suit battlefield conditions.? As a Software-Defined Radio (SDR), the HCR's unique architecture facilitates technology insertions while allowing for interoperability with legacy platforms, including the Ultra AN/GRC-245 and AN/GRC-512 radios.

    Iwan Jemczyk, President of Ultra Electronics, TCS commented:
    "The new version of the Ultra HCR introduces truly breakthrough technology in its domain and represents the culmination of Ultra's forty years of experience delivering tactical communications solutions. The radio's small form factor, significant bandwidth throughput capability and its ability to evolve over time, opens doors to new applications at all levels of the tactical communications chain."

    Ultra Electronics, TCS
    Ultra Electronics, TCS, part of the Ultra Electronics group, is a global leader in tactical communication systems, including high-capacity radio communications and Electronic Warfare (EW) systems. Ultra TCS supplies dependable, reliable and powerful communications equipment for tactical military and defence system applications. The company's products are tailored to meet or exceed military requirements in order to ensure that reliable, effective and robust communications can be deployed in the most rugged of environments. Ultra TCS is proud to work with leading system integrators to provide the best communications systems and services to be integrated within any military architecture and fielded as part of any deployment scenario in the world.
