How to Choose a CMS for Content Marketing

14 03 2016

My college roommate used to hold up his giant screwdriver and say – “this is the only tool I’ll ever need.” And, he’d hammer nails with it, open boxes with it, open beer bottles with it (yes, college was like that for me). It was everything he needed. Sadly, the same can’t be said for different web content management software.

So, if you’re neck deep in a content marketing strategy, it’s a sure bet that you’re also, in some way, wrestling with a web content management system (CMS). Whether you’re publishing a blog, a web site, multiple web sites, landing pages or just throwing press releases up on Marketwire, chances are it’s not hand-coded HTML being FTPd by Dreamweaver.

And if it is. . . well, read on friend, because you need a web content management system in the worst way.

There’s a good chance that – despite how much you love or hate your CMS – it may be a time bomb in your back room, bringing all of your hard, creative content marketing efforts to a dead stop.

What is a CMS?

A web CMS the application you use to publish and manage web content.

Is WordPress a CMS? It’s a question that many in the CMS community can’t agree on, so is it any wonder that marketing folk have a hard time distinguishing between the thousands of products on the market?

For the record, I argue that WordPress is a CMS – if only because a blog is web content, and WordPress is a way to manage that content. But then I’d also argue that if you have someone named Bob or Mary transforming your Word doc into HTML and putting it up on your site, that you have a CMS called Bob or Mary.

How do I know which CMS is right for my organization?

Decide what you need your CMS to do
Any decent CMS (including Bob or Mary) will enable you to publish content to the web. The key is to understand not only what you are trying to manage, but how it is you’ll manage it. For instance:

  • Is it a blog? Will it have private membership?
  • Is it a corporate Web site that will have multiple authors across the business, where content is targeted to different personas?
  • Is it a multi-language e-commerce platform? Learn more about headless cms.

Don’t under-buy or over-buy
There are real differences in what you can (or can’t) do with Bob or Mary, or with a blogging tool like Movable Type or WordPress, and what you can (or shouldn’t) do with an enterprise-class web content management solution. The trick is not to under-buy or over-buy technology just to escape the “IT Bottleneck.”

Consider using multiple systems
Understand your process and the kind of web properties you are about to publish before you go out looking for tools. And, certainly don’t be afraid to use different tools for different types of content.

Blogging tools are really good at what they do. If you’re happy using WordPress for your blogs and microsites but you need to add more rigorous workflow to the corporate site – don’t succumb to the idea that EVERYTHING has to come out of one system. CM systems are almost always geared toward publishing different kinds of sites, and it’s now very easy to integrate content in and out of different CM systems.

Choose a tool that aligns with your process
The key to aligning your shiny new web content management system to your content marketing strategy is to understand that the tool is just the facilitation of the process. Like any tool, it’s just leverage. In Joe Pulizzi’s August post, “How To Effectively Manage the Content Marketing Process,” he identified these key tools:

  • A content management system
  • Listening posts
  • The Project Manager and the Managing Editor
  • The editorial calendar
  • The dynamic budget

The right CMS for the job – one that provides you with control and facilitates YOUR process – is one that both talks (publishes) and listens (ingests) content. It enables the Project Manager and the Managing Editor to establish editorial calendars and manage workflow – and provides insight into how that content is performing so that you can keep budgeting effectively.

Don’t be afraid to add tools to your toolbox as you need them. Having a screwdriver prevents you from failing. Having a whole box full of the right tools to manage the job correctly is what makes you successful.

Drive Safe: Tips for Adjusting to “Standard Time” This Weekend

13 03 2016

Why is driving at Sunrise and Sunset an Increased Risk to Safety?

  • At sunrise and before sunset the sun can shine directly into drivers’ eyes, leaving many motorists driving with a glare.
  • This leaves the driver’s view compromised making it much harder to see the road ahead and identify potential hazards.
  • At dusk/sunset, your eyes must adapt to the changing level of brightness, and it becomes more difficult to recognize threats to safety.
  • Although the sky may still be light, the road will be darker with deep shadows, and there is less contrast in colors (i.e., the color of oncoming cars).
  • It will leave the driver closer to any hazard and leave a much-reduced stopping distance.
  • Visibility is particularly poor at dusk and dawn because natural light is reduced and it is not dark enough for your headlights to be 100% effective.
  • Driving at these times is often associated with tiredness among drivers who have driven through the night or are returning from a hard day of work.
  • Exhaustion severely affects focus and reaction time, so it is advisable to keep driving to a minimum in these circumstances.
  • It is especially dangerous for the elderly drivers experiencing natural, age-related changes in vision.

Vulnerable Road Users

Not only drivers of motor vehicles and trucks share the roads at sunset and sunrise. It is important to recognize that many other more vulnerable road users may be sharing the roads at these times.

  • Be very alert to the pedestrian heading to and from work and especially the child pedestrian.
  • Many runners/joggers use the roads at these times for a training run.
  • Cyclists also most often do their training rides at this time when it is not so warm.
  • They may be especially vulnerable when heading towards the direction of the rising and setting sun when passed by faster moving vehicles and drivers with reduced visibility.
  • As drivers tend to focus on driving more to the side of the road in reduced visibility, it significantly increases the risk to cyclists.
  • Most crashes into cyclists occur on weekday afternoons, and the risk of cycle accidents is 4-5 times greater in darkness than in daylight.
  • Cycling with a front and rear light will make you more visible, especially in the early morning or evening.  Use a flashing red light at the rear and a solid beam white light at the front.
  • Cyclists need to remain very attentive to driving as close to the side of the road as possible and remain in single file.
  • Drivers in rural areas need to remain attentive to the presence of livestock and wildlife, particularly around and after sunset.

Safe Driving Techniques When Driving at Sunrise and Sunset

Preparedness of the Driver

An informed road user is a safer road user. We would like drivers to be alert of risks, to be well prepared and able to make the necessary adjustments when required.

  • Think ahead of the planned drive, the potential threats on the road and be ready to adjust the way you drive.
  • Many drivers can self-regulate by limiting their driving in low light situations, such as at dusk, dawn or night.
  • Ensure alertness by avoiding driver tiredness, planning your rest stops and avoiding all driver distractions.
  • Be mindful of other drivers, and switch to your low beams if there’s oncoming traffic or if you are following another vehicle.
  • Have good sunglasses available to you within easy reach.
  • Invest in polarized sunglasses – they can help reduce glare.
  • Avoid wearing tinted sunglasses at night, though they may be helpful during dusk and dawn when the sun is still out.
  • Utilize your sun visor – it can help to block out the sun.
  • Let your eyes adjust – The human eye naturally adjusts to the darkness, but it can take up to 30 minutes for your eyes to adapt to darkness fully and drivers should reduce speed during this transitional time.
  • Be conscious of vision changes. As we age, it is natural to experience vision changes that affect our visibility in low light situations, such as dusk and dawn.
  • A 50-year-old driver may need twice as much light to see comfortably over a 30-year old driver.
  • Limited light can affect depth perception, color perception, contrast sensitivity and peripheral vision.
  • Get regular check-ups for conditions like macular degeneration, cataracts, and glaucoma.

Healthy lifestyle tips

13 03 2016

Sometimes it can feel like maintaining a healthy lifestyle is an overwhelming challenge that doesn’t fit within the realities of daily life. It’s tough to hold down a full-time job, eat well, train for a marathon, make homemade green juice, spend quality time with your family/partner, and meditate for an hour each day. ? Visit sfexaminer for more detailed information about healthy supplements.

Of course, healthy living can incorporate all of these things (if you want it to), but it doesn’t have to be defined by grandiose displays of health and fitness.

So much of healthy living is really made up of small things we do daily—things that are so small they don’t feel momentous, but that, done consistently over time, add up to produce big results.

According to dr homan omaha ne, Oral health care in pregnancy is often avoided and misunderstood by physicians, dentists, and patients. Evidence-based practice guidelines are still being developed. Research suggests that some prenatal oral conditions may have adverse consequences for the child. Periodontitis is associated with preterm birth and low birth weight, and high levels of cariogenic bacteria in mothers can lead to increased dental caries in the infant. Other oral lesions, such as gingivitis and pregnancy tumors, are benign and require only reassurance and monitoring. Every pregnant woman should be screened for oral risks, counseled on proper oral hygiene, and referred for dental treatment when necessary. Dental procedures such as diagnostic radiography, periodontal treatment, restorations, and extractions are safe and are best performed during the second trimester. Xylitol and chlorhexidine may be used as adjuvant therapy for high-risk mothers in the early postpartum period to reduce transmission of cariogenic bacteria to their infants. Appropriate dental care and prevention during pregnancy may reduce poor prenatal outcomes and decrease infant caries.

Comprehensive prenatal health care should include an assessment of oral health, but this is often overlooked.1 Only 22 to 34 percent of women in the United States consult a dentist during pregnancy. Even when an oral problem occurs, only one half of pregnant women attend to it.2 This problem is compounded by a lack of national clinical guidelines for the management of common oral conditions in pregnancy. The American Dental Association and the American College of Obstetricians and Gynecologists provide only advisory brochures on oral health for pregnant patients. New York recently became the first state to create an evidence-based prenatal oral health consensus document.3 In the absence of practice guidelines, fear of medicolegal action based on negligent or substandard treatment of oral conditions during pregnancy abounds, but it is largely unfounded

Wellness tips for healthy & happy living

Here are 31 tips to live a healthier, happier lifestyle—all simple, easy things that can be seamlessly incorporated into your daily life:

1. drink a glass of water first thing in the morning

Coffee’s great too, but it’s best to start your day by re-hydrating with a full glass of water. Hydrating first thing in the morning helps to aid digestion, enhance skin health and boost energy.

2. take the stairs

Taking the stairs instead of the elevator is a simple way to get a little more physical activity in your daily life. It also strengthens and tones your legs and core while you’re at it!

3. make half your plate veggies

A simple hack for healthy eating (and portion control) is to make half your plate veggies at each meal. The veggies pack in essential vitamins, minerals and other phytonutrients important for health and longevity. And, because they’re rich in fiber, they help to aid digestion (aka keep you regular!) and keep you feeling full longer.

4. get a fitness tracker + track your steps

Using a fitness tracker (like a Fitbit or Apple Watch) to track your steps is an easy way to make sure you’re getting enough physical activity each day. We aim for 10,000 steps daily, which has significant physical and mental health benefits. A fitness tracker will also remind you to get 250 steps each hour (another important measure of health—see tip #9!). Here are our favorite fitness tracker smartwatches of 2021.

5. switch to non-toxic household cleaning products

Conventional household cleaning products are full of harmful chemical ingredients that are not good for our health (or the health of our kids or pets!). Switching to healthier alternatives is a simple way to reduce your exposure to environmental toxins in your home. See our Healthy Cleaning Guide for a complete list of recommendations, and what to look for when choosing safer household cleaning products. Check out the latest java burn reviews.

6. use non-toxic skincare + personal care products

Similar to cleaning products, conventional skincare and personal care products are formulated with toxic ingredients we should not regularly let absorb into our body’s largest organ. Reduce the toxic burden on your body by switching to non-toxic personal care and beauty products (see our specific recommendations on deodorant, sunscreen, and green beauty products).

7. take a probiotic daily

Maintaining a healthy gut has significant impacts on digestion, skin health, immunity, mental health and more. Taking a daily probiotic with a glass of water each morning is one of the simplest things you can do to boost your gut health (which, in turn, boosts overall health in many ways too). Learn more about the health benefits of probiotics (and all the ways to get them in your diet), and shop our favorite probiotic supplement here.

8. eat real food

Aim to eat real food that’s made of whole food ingredients you would have in your own kitchen pantry, or that your grandmother would recognize. (Yup, this rules out most packaged food, sorry!) This is a little different than suggesting you eat only “health foods” (many of which are increasingly processed!). “Real food” includes unprocessed foods like an apple, a cucumber, soybeans or a steak, as well as foods loosely processed from one (or few) real-food ingredients, like butter, olive oil, yogurt, tofu, etc. In other words, aim for foods that could be reasonably made in your own kitchen and avoid foods that can only be made in a lab.

9. stand up every 30 minutes while working

Reduce the harmful effects of sitting (like at your desk job) by standing up and moving around for a minute or two every half hour.

10. get sunlight every day

Vitamin D is one of the most important nutrients for overall health, and sunlight is one of our best sources of it. Aim to get at least 30 minutes of sunlight each day—preferably in the afternoon, and without sunscreen (read more about that here). Not much sunlight in the winter where you live? It might be worth supplementing with a vitamin D supplement and/or other food sources of this essential nutrient.

11. fill your home with houseplants

Houseplants help to cleanse your indoor air (sadly, it probably needs it!), they’re pretty, and research even shows they improve mood, creativity and problem solving!

12. sweat every day

Aim to sweat in some way each day—whether that’s via running, biking, dancing, hot yoga, or any other physical activity you enjoy. See our Fitness Guide for more workout ideas, as well as tips and tricks for building regular physical activity into your daily life and a downloadable fitness planner you can use to outline your own custom fitness plan to stay on track.

13. have a daily green smoothie

Green smoothies as a snack or simple, on-the-go breakfast are an easy way to get your greens in each day. Check out our curated list of healthy (veggie-packed!) smoothie recipes for our favorite starter green smoothie recipe ideas.

14. work hard + be kind

Enough said!

15. cultivate a positive mindset

“The only difference between a good day and a bad day is your attitude.” It’s true—mindset is everything! Cultivate a positive mindset by recognizing negative thought patterns and countering them with positive thoughts or affirmations. Here are more mindset resources for positive thinking.

16. get enough sleep

Most adults need 7-9 hours of sleep each night. But in addition to quantity, quality of sleep matters too! Follow our tips on getting quality sleep—things like keeping your bedroom cool at night, avoiding blue light after dark, and more.

17. start your day with a healthy morning routine

Start each day with fulfilling activities that set the tone for how you want to feel—whether that’s inspired, relaxed, productive, or something else. ? Check out our list of ideas for starting a healthy morning routine to start your day right!

Théorème des 4 couleurs

6 01 2016

En 1852 Francis Guthrie, cartographe anglais, remarque qu’il lui suffit de quatre couleurs pour colorer la carte des cantons d’Angleterre, sans donner la même couleur à deux cantons adjacents. Il demande donc à son frère Frederick, mathématicien, si cette propriété ne serait pas vraie en général pour toute carte plane ; celui-ci communique la conjecture à De Morgan, et en 1878 Cayley la publie.

En 1879, Kempe trouve une première preuve de la conjecture, mais onze ans plus tard Heawood y trouvera une faille majeure ; il parviendra toutefois à en sauver un théorème des cinq couleurs. Une seconde preuve par Tait en 1880 sera de même réfutée par Petersen en 1891.

En 1913, le père de l’algèbre moderne, G. D. Birkhoff démontre la conjecture pour toutes les cartes comportant moins de 26 régions à colorier. Cette borne est améliorée au cours du XXe siècle ; en 1969 Heesch trouve des conditions presque nécessaires et suffisantes pour qu’une configuration soit réductible, et une méthode générale pour trouver un ensemble inévitable de configurations.

Finalement, en 1976, Appel et Haken réalisent le programme de Heesch, et montrent, dizaines de milliers de figures à l’appui, que toute carte non 4-coloriable doit contenir l’une de 1 478 configurations, et, avec 1 200 heures de calcul, que chacune de ces configurations sont réductibles.

Enfin, en 1995, Robertson, Sanders, Seymour et Thomas mettent à profit la formidable accélération des ordinateurs pour trouver une réalisation nettement plus simple du programme de Heesch, avec seulement 633 configurations.
