Walton LAX & Team Training – Crossfit NBK
CrossFit NBK is officially the training ground for Walton LAX athletes. We are proud of this role and look forward to helping both up and coming athletes and the current team.
We are currently working with LAX athletes and families for the season, and will host a Walton LAX training sessions beginning in 2020. Details are below!
It is incredibly important for athletes to continue to lift weights and workout even while they are ‘in-season.’ There is a lot of research out there that has confirmed this idea, so moving forward we will be adding this into our program in the spring. I realize many of our varsity athletes haven’t done this in the past and so we are not launching this plan as an expectation for them, but rather building into the future by starting with our JV first.
I do highly suggest our varsity players continue to lift weights (around our schedule of games) because it assists in muscle recovery and injury prevention when done correctly. At our next coaches/players meeting I am going to explain more on this subject with our boys to help set them up for a good plan in the spring. The NBK option will also be available for them.
The JV plan is that for all listed times on the spring calendar titled “NBK Lifting” our JV team will work out together as a team development and bonding event. We cannot mandate this, but I would like to direct all JV players to sign up and attend. I have coordinated with NBK Crossfit on exactly what impact we want this to have on our players, which is to focus on muscle recovery, hip functionality, balance improvement and flexibility, and leg strength throughout the season. We have selected the dates to work around game schedule in such a way that the boys should be fresh for their games and this will assist in injury prevention and athletic development over a long-term career at Walton.
I am unable to coordinate times always in the weight room in the spring as there are so many moving parts, and this becomes the easiest and most effective plan I can implement for our program. It is also incredibly cost effective.
Details of the plan:
· Players pay $67 when they register for NBK Crossfit (which is an unreal price for what we are getting), with 15 athletes registered
· That gives them 20 sessions as a team with multiple trainers that have worked to create a personalized program for our team and are focused on our team during those time slots
· The dates were selected to best fit with the JV team schedule of practices and games – those 20 dates are spread out over the entirety of the spring so it is not a huge addition to their schedule and the output potential will raise each of their ceilings
· The facilities at Crossfit NBK are unbelievable with what they are able to do in training up athletes and the knowledge of training and programming is as high quality as it gets
· VARSITY OPTION – varsity players will have the option to pay $50 and receive a punch card for 15 sessions that they can show up to at any time as long as it is during one of the 20 JV session time slots OR one of the regularly scheduled classes at NBK Crossfit during the entire spring from January through May.
Dates are planned as follows:
- Wednesdays (all from 3:30pm to 4:30pm) LAX Only:
- Saturdays (February 1st would be 12pm to 1pm, all others would be 10am to 11am) LAX Only
Additional Group Days as part of NBK Classes:
- 3/16 from 5pm to 6pm
4/13 from 4:30pm to 5:30pm
4/20 from 4:30pm to 5:30pm
4/22 from 4:30pm to 5:30pm
4/28 from 4:30pm to 5:30pm
4/30 from 4:30pm to 5:30pm
Do you want to become a more efficient athlete? Do you want to become faster, quicker and have more body control? Is your desire to develop your speed, strength, and motor to make the team and then help your team win the game? The athlete training sessions are the perfect environment for the developing and developed player to train to become more explosive and faster. By learning the correct movements (things that often seem “natural” but need to be learned correctly), a player can improve their effectiveness dramatically.
Our athlete training sessions with NBK Coaches at CrossFit NBK are designed to build great athletes, not just great players. Preseason and the offseason are the perfect time to take your game to the next level by improving your explosiveness, efficiency, and conditioning. NBK will use a variety of training methodologies that include CrossFit, aerobic capacity, strongman, and gymnastics that develop body awareness exercises aimed at building strength and all around fitness, using climate controlled facility, weight training (depending on age), and much more.Where

Inaccurate Airport Luggage Scales Could Cost You Big Money – CBS Los Angeles
By David Goldstein
LOS ANGELES (CBS) — If you are flying this holiday season, how do you know the luggage scale at the airport is accurate? Before you get hit with big fees, take a look at what we found.READ MORE: Smoke Advisory Issued For Orange County Due To Chaparral Fire
Sue Gibbs’ friends and family went through LAX on vacation to Hawaii. They did not want to get hit with added charges that they did not deserve for overweight luggage.
“They charge you so much once you get here and if you’re one pound over, you’re a goner,” Gibbs said.
But a video that we obtained of a scale at LAX showed a 50-pound weight coming in at 53 pounds and 100-pound weight at 109. A faulty scale like that could cost you big bucks, no matter which airline or airport.
Jessica Windsor and her 8-month-old son Levi checked in their duffle bags at Ontario Airport on their way home to Wyoming after visiting grandma in Murrieta.
“To do a service to the public, I think it would be nice to know the scales were right on and weighing in correctly,” Windsor said.
Before you head off for holidays, toting that overstuffed suitcase, we obtained dozens of pages of inspection reports of airport luggage scales at LAX, John Wayne, Bob Hope and Ontario Airports. Many passed inspection, but it only takes one for you to get hit with big fees.
We found reports of scales labeled abnormal performance; complaints by passengers of incorrect weights that were found to be valid; and some marked RT (red tagged) taken out of service.
All of the counties inspect the scales once a year — it is mandated by law. At LAX there are more than 400 scales and each one has to be certified.
Using weights, Leland Anderson checks the scales for the county.
“Twenty five in the middle, perfect.” Anderson said confirming a test.
The test involves big weights, like 250 pounds, to the smallest increments.READ MORE: Mass Exodus From South Lake Tahoe; Evacuation Orders Issued For Entire Basin
“We’re going to add one tenth of a pound — goes right to 50,” Anderson said referring to a scale during an inspection.
If they pass they get a county seal, but some flunk the weigh in.
“Scales are not perfect. They’re electrical devices subjected to wear and tear, abuse, several people standing on them at once, pushing it around all day,” Anderson said.
He took a video of a Delta scale at LAX last February. It registered 6 pounds with nothing on it and 53 pounds with a 50-pound weight. That might not sound like much, but 3 pounds over the 50 pound limit on delta would cost you $90 in overweight baggage charges.
So here is what you need to know before flying. According to the reports, 94 percent of the scales at LAX passed routine inspection; 98 percent at John Wayne airport; 100 percent at Bob Hope; but only 73 percent passed inspection at Ontario Airport.
Some flunked for accuracy, others mechanical problems and a few even came in underweight in favor of passengers. All were eventually corrected.
Here are the numbers broken down by the major airlines at all four airports, according to the reports we obtained.
- American Airlines: 37 passed, none failed
- Southwest Airlines: 33 passed, none failed
- US Airways: 24 passed, one failed
- United: 66 passed, two failed
- Delta: 40 passed, 12 failed
- View All The Numbers
A recent study of baggage fees by the Bureau of Transportation shows Delta has taken in the most money this year — nearly a half billion dollars — and far more than American, which came in second and US Airways, which is third. That includes all money collected for baggage nationwide.
So how do you know if your suitcase is really overweight? They recommend weighing your bag on another scale at the airport before checking in. It should show the exact same amount.
“We would not be paying the extra. No.”
Good advice so your vacation doesn’t get weighed down with heavy fees that you don’t deserve.MORE NEWS: Lack Of Trash Service Shuts Down Several Angeles National Forest Campgrounds

How much should a baby weigh?
The World Health Organization recommends weighing babies from 0 to 2 months every week. The child’s weight is then assessed monthly until he is one year old. Normal indicators of weight gain are:
- from 0 to 4 weeks – 500-1200 grams
- from two months to six months – from 400 grams
- from six months to a year – 200-300 grams every month.
Important! Increase in height and weight is an individual matter. The kid may well fall short of the norm, but at the same time feel good, eat normally and develop. If so, then don’t worry. Your child is absolutely healthy. Underweight is a feature of its physiology.
When to worry?
If a slow weight gain in a baby is accompanied by lethargy, pallor, whims, frequent regurgitation, fever or loose stools, this is a reason to contact a pediatrician.If the baby began to lose weight in the first months of life, in no case should you postpone the visit to the doctor. Most often, the causes of underweight are harmless enough. The situation can be corrected by establishing breastfeeding or adjusting the diet of the mother and baby. However, in some cases, we can talk about congenital pathologies or diseases. The true cause must be determined by the doctor.
Causes of underweight in children under one year old
Most often, babies gain weight poorly due to improper feeding techniques.Lactation counselors recommend placing the baby to the breast or giving him a bottle on demand. Some babies sleep so well at night that they don’t wake up hungry. Perhaps this is your case. At night, a month-old child should eat every three hours, at the age of two to ten months – 2-4 times. The infant may have a weak sucking reflex. If he eats slowly and with difficulty, he needs to be helped by lightly pressing on the chest while feeding. If you have flat nipples, you can turn on the breast pump for a couple of minutes before feeding, and then offer the breast to the baby.If the baby is nervous and capricious during feeding, you need to eliminate the cause of his anxiety. How to do this, you can read here . Sometimes the baby does not have time to get to the fatty and nutritious “back” milk. This is due to the fact that mom offers him a second breast ahead of time. This should be done only when the baby completely empties the first.
If the baby feels good, moves actively, plays a lot, does gymnastics or baby swimming, then he will weigh less.If the reason for underweight lies in high physical activity, do not worry.
Sometimes the reason lies in the genetic predisposition of the baby. With his thinness, a child can become a parent. Underweight in infants is often associated with malfunctioning of the gastrointestinal tract. Most often this happens due to the fact that the baby’s body does not absorb certain nutrients. Constipation, diarrhea, or an imbalance in the gut microflora can also lead to slow weight gain.If your baby has digestive problems , it needs to be shown to the doctor.
If the baby has recently been ill, he may not gain weight for some time. In this case, the baby needs to be fed with milk or artificial nutrition in the usual amounts. After a few days, the body of the crumbs will recover.
In the most rare cases, worms can become the cause of underweight in a baby. If you have come into contact with animals on the street or you have pets, the baby should be shown to the doctor and tested just in case.
Important! Lethargy, pallor and poor appetite in infants can be a signal of various pathologies of internal organs. Underweight combined with vomiting and high fever indicates a protracted viral infection. With such symptoms, the baby needs to be urgently shown to the doctor.
Helping your baby gain weight
If the baby is at least 300-400 grams behind the norm, and his health makes you anxious, you cannot do without consulting a pediatrician.The specialist will be able to make the correct diagnosis and, if necessary, prescribe treatment. When it comes to underweight due to feeding problems, doctors recommend the following:
- In the first months of life, the baby should be frequently applied to the breast. Scheduled feeding is not suitable for all babies. It is necessary to listen to the opinion of the crumbs, who begin to cry loudly, pull their fists into their mouths and look for breasts when they want to eat.
- If the baby is weakly breastfeeding and constantly loses it, show it to the pediatric dentist.The baby may have problems with the structure of the palate or the hyoid frenum.
- Hold the baby at one breast until it is completely sucked. It usually takes 20-30 minutes for kids to do this. If the baby is on IV, consult a doctor and try to replace mixture . It should be easy to digest.
- If the baby does not wake up from hunger at night, it needs to be woken up and applied to the chest. In the first month of life, the baby should eat at night every three hours, and then two to four times up to ten months.
- In the first month of life, the baby should write up to 20 times a day, after a month – about 15 times. If the baby gives you wet diapers less often, it means that he does not have enough breast milk. In this case, the child needs to be shown to the pediatrician and, if necessary, switch to mixed feeding.
- The diet of a nursing mother should be varied and nutritious. All bad habits for the lactation period must be abandoned.
- Before feeding, go outside with the baby, play, do gymnastics.Physical activity will help the baby to work up an appetite.
Summary: A baby may not gain weight for a variety of reasons. To exclude serious diseases and pathologies of internal organs, the baby must be shown to the doctor.90,000 How do you know your ideal weight? Nutritionists have updated the well-known formulas
Scientists have conducted new studies that have led to interesting conclusions.
The problem of excess weight has received a lot of attention in recent years.The question: “How to eat everything you want and not get better” – torments not only the weaker sex, but already the strong half of humanity. Fashionable and effective diets have flooded the internet. The profession of a nutritionist has become, if not the most popular, then it has become one of the most widespread. Such an excessive fascination with the topic has led to a fundamental division: some decide to give preference to healthy eating, while others, on the contrary, elevate food to a cult, trying to prove that “plus size” is not excess weight, but a sign of love for life and acceptance of oneself as you are.
While both are hotly debated, scientists have introduced new standards for average weight, as a result of which some even have to gain a couple of extra pounds.
Each has its own formula
A good nutritionist will never tell you, “You need to lose ten pounds.” A true professional will explain to you that the ideal weight is an individual thing. To derive its formula for each, it is necessary to take into account both height and gender, the type of your figure, even the ratio of fat (and thin people also have it) and muscles, and especially your chronic diseases.
Nutritionists have developed several new formulas that are simple, but at the same time allow you to get an indicator of the “new normality” of the ideal weight of men and women.
Dr. Lorenz Method # 1:
Lorenz invented an even more simplified formula for calculating weight:The formula looks like this: (height (cm) – 100) – (height (cm) – 150) / 2 =?For example, your height is 176 cm.(176 – 100) – (176 – 150) / 2 = 63The ideal weight for a height of 176 cm is 63 kg.
Dr. Lorenz Method # 2:
(height (cm) / 2 ‑25 =?For example, your height is 180 cm.
180/2 – 25 = 65
Ideal weight for height 180 cm – 65 kg.
We take into account anatomical features
However, according to experts in the field of nutrition, the Lorenz method is not perfect. More advanced techniques also take into account three body types: asthenics, normosthenics and hypersthenics.
Asthenics have narrow bones, long limbs and a thin layer of subcutaneous fat. The anatomical features of normosthenics are almost averaged parameters.But in hypersthenics, as a rule, although they are not tall, they have well-developed muscles.
According to the new formula, the ideal weight for men with a height of 180 cm
Asthenics – from 65 to 69 kg.
Normostenics – from 67-74 kg.
Hypersthenics – up to 80 kg.
Ideal weight for women with a height of 170 cm
Asthenics – 53-57 kg.
Normostenics – 59-60 kg
Hypersthenics – up to 67 kg.
You can determine your type by the circumference of the hand: in asthenics it is less than 16 cm, in normosthenics – from 16 to 18.5 cm, in hypersthenics – more than 18.5 cm.
Everything changes with age
The Egorov-Levitsky table is widely used by Russian nutritionists.You just have to enter your height and age, and you will find out your ideal weight.The data in the table will surprise you: a man from 20 to 29 years old with 180 cm in height can weigh 85 kg. With the same initial weight, a woman can be 80 kg. The estimated weight of a man from 30 to 39 years old with a height of 170 cm is 77.7 kg. Women – 75 kg.
According to the latest research, a modern woman weighs an average of 6 kg more than 20 years ago. And the average indicator of both sexes increased by 5 kg. Poor metabolism and even ecology play a role here.Well, and, of course, the main reason for both obesity and weight deficiency is almost always the same – unhealthy diet.
How to choose the right kite according to wind strength and riding level.
Selection of the size of the kite by wind strength
Choosing a kite is the most important moment when you are just starting to master this water sport. Your further safety in the water and the safety of the kite itself will depend on which kite you choose. With the correct calculation of all the necessary parameters before buying a kite, you can guarantee yourself that it will be easier to cope with the kite.The correct size of the kite will increase the speed of kitesurfing.
Choose your kite size based on 2 criteria: wind strength and dead weight. Strong winds will require a smaller kite, and light winds will require a larger one. The more your weight, the more the size of the kite is needed. If the kite is of insufficient size, then it will only bring you unnecessary inconvenience at the start and when riding upwind. And if the kite is too big, you can easily lose control over it.
You also need to remember that the wind is constantly changing. A certain area of the kite has a working thrust in a specific wind range. Therefore, those who are serious about kiting have several kites for different wind strengths. 2-3 kites with a traction control system (deep power) cover up to 90% of the existing winds.
Kite size selection table in m 2 from wind speed when riding on water:
Kite size selection table in m 2 from wind speed when riding on dense snow:
Structurally, kites are divided into two main types.
Balloon (inflatable) kites are usually used on water. For winter and for riding on hard surfaces, kites with open air intakes – parafoils are also suitable.
The main feature of this type of kite is the inflatable bladders. Thanks to the inflatable frame, the required canopy shape is created, and the kite under no circumstances loses its shape and does not sink. The canopy balloons are located both along the leading edge and across the kite. Due to the inflatable frame of the kite, the canopy cannot scoop up water and lose its shape.
However, it is worth considering that when the kite falls to the ground or to the water, a strong impact occurs, which can lead to a breakthrough of the shell or internal cylinders.
Not long ago, this type of kite was used only on the water, but in recent years they have practically replaced parafoils from freestyle snowkiting.
Classic kite – C-type
Inflatable horseshoe kitesThe advantage of this type of kite is stability and excellent controllability, but compared to other types, the wind range on such a kite is very narrow – you can control the thrust only in a small range of wind strength.This type of kite is maneuverable and extremely dynamic.
The disadvantage of a C-type kite is a rather difficult restart of the kite from the water. If the kite falls into the water with its leading edge, then to restart it you need to turn it over onto its back, for which you will have to swim towards it, pulling up the front lines. The solution to this problem was the introduction of the fifth line, because with its help the kite can be restarted without much effort, and relieve it of traction when taking off from the center of the wind window.
The presence of the fifth line has its drawbacks.If the kite falls and turns around the longitudinal axis, the additional line may be a noose for the canopy, because it will pull it in the center, which, accordingly, can cause the kite to split across to the central balloon. To avoid such an incident, modern manufacturers have introduced an element of the fifth line uncoupling, which will help free the snake from suffocation.
Flat arch kite – Bow
Inflatable kites with a flat profileA distinctive feature of these kites is the flat arch of the kite.This type of kite has a wide wind range, as well as the ability to completely get rid of traction and can be easily restarted from the water. To restart, just pull the side line – the kite turns over and then the restart is performed.
Bow kites are safer than C-type kites: when the kite falls from the thrust zone, the force of the impact is almost evenly distributed throughout the kite, which seems to spring on impact and, therefore, will last longer. Also, if you lose control of the kite, when it starts to twist in the power zone, the Bow practically loses power, and gives you the opportunity to regain control over itself.
The main disadvantage of Bow kites is the ability of the kite to turn inside out. This usually happens when there is a gusty wind, when there is a turbulent flow – in this case, the kite can fly over the head, leaving the thrust zone, the lines sag, the wing turns out and falls. This situation must be prevented even when the kite is flying over the head, and this depends on the rider’s experience.
Another drawback is the lack of stability in the side edge of the window. The sidewall of the canopy has a smaller support area than a C-type kite, which means it is more difficult for the kite to stay in the edge of the window.A light turbulent flow or light wind can cause the kite to fall or roll, but this rarely happens for experienced riders.
Kite with wide wind range and restartableHybrid kites also fly as great as the C-type, are as easy to restart as Bows and have a fairly wide wind range.
There are a lot of hybrid kite options. They can be from completely flat to arched C-types of reduced size.Hybrid kites usually have a front bridle with four-line control, but there are also models with a modified fifth line.
Many manufacturers today prefer the creation of hybrid kites, since they have practically no drawbacks like bow kites or classic C-type kites.
The main characteristics of hybrid kites are mainly determined by the shape of the wing. To understand and predict the behavior of the kite, you need to study the description of a specific model, determine for what purpose this kite was designed, watch video presentations and riders’ reviews of this model.
Designed for riding on snow, on land and on iceParafoils are common for winter skiing, but recently they have been actively replaced by inflatable kites.
The dome of the kite consists of 2 surfaces: upper and lower. The surfaces are connected by vertical ribs that shape the wing section, while dividing it into sections. The wing of the kite on the leading edge is open for the oncoming air flow.
The wing has no rigid frame. The shape of the canopy is supported by a system of under-the-hood slinging, and the air flows add the required volume to the canopy.
The advantage of parafoils over inflatable kites in a lower price – as they are easier to manufacture; in durability – since they do not receive damage when dropped; in quick preparation for skiing – since they do not need to be inflated with air.
The lack of parafoils is the lack of versatility – they are designed for landkiting or snowkiting and are almost never used for riding on water, since they lose their shape when dropped, which means they do not have the ability to restart from the water.
According to their purpose, kiteboards can be divided into three main groups, differing in shape, materials used and construction.
Basic water boardThe small twin tip is easier to handle in the sidewind, besides, the short board increases the ability to move upwind, makes it easier to control the kite’s traction, plus it has good maneuverability.
The use of modern improved materials, concave and other innovations significantly improve these indicators.
Additional advantages of a short kiteboard: less weight, takes up less space and gives more pleasure both on the wave and on the flat, as it allows you to move more aggressively.
Designed to ride on water in light windIf you want to ride confidently in very light winds and enjoy it, you can purchase a light windboard – a specialized board for this purpose.
The light windboard has significantly better light wind potential.Due to its large size, this board is more stable and provides a smoother ride.
This board begins to float and lift the kiter above the water in significantly lighter winds and therefore at a lower speed, making it a versatile training tool.
Great for surfing the wavesSuch a board has a unidirectional shape, increased buoyancy and in most cases does not have leg loops.The geometry of the kite surfboard is perfect for riding the waves.
Additional features of the surfboard: it is easier to cut to the wind – “gain altitude” and it has an increased wind range – allows you to ride in very light winds.
It is more difficult to make turns and changes of direction on a surfboard, at some moments you cannot do without a complete stop. The surfboard is not suitable for jumping and other tricks.
A surfboard on a kite is more fragile – it can be damaged if handled carelessly, and bulky – inconvenient during transportation.
The main dimensions of the length of kiteboards are in the range from 132 to 146 cm (depending on the rider’s weight), however, for the first starts in kiteboarding during training, we recommend a board with a length of more than 150 cm.
Much depends on the wind conditions and your riding style. For example, in your region strong winds prevail in winter, therefore you need to choose a kiteboard of less length; and in summer the wind is weak, so it makes sense to choose a kiteboard along the upper border.
Recommended table for selection of a twin-tip kiteboard with wind over 6 m / s:
|Rider weight, kg||up to 50||51 – 60||61 – 70||71 – 80||81 – 90||90 – 100||100+|
|Kiteboard length, cm||up to 130||129 – 133||130 – 136||134 – 140||139 – 145||145 – 155||155 – 165|
90,000 Child’s appetite disorder, underweight
Appetite is an emotional desire of a child due to various factors to consume a certain food.Unlike hunger, appetite is associated with pleasant sensations and can occur regardless of the feeling of emptiness in the stomach.
A child’s appetite is formed at an early age on the basis of the behavior of parents and traditions in the family, acquired experience and individual characteristics and preferences of the smallest person.
A child’s appetite can change over time and even over the course of one day. This is influenced by factors such as the quality of the food, the type of preparation, the way of serving, the external environment, etc.It is very important to understand when the child is really full, and when, for some reason, the appetite has decreased, and disorders have occurred in his body.
In infants, the feeling of satiety is expressed in tearing away from the breast or nipple after receiving a sufficient amount of milk or formula, in older children – covering the mouth with a hand, turning away from a spoon, or playing with food on a plate. In this case, forced food intake in children can cause a negative reaction and the development of a negative reflex to food, psychogenic anorexia, accompanied by vomiting during meals and further weight loss.Shy, withdrawn children can also suffer from psychogenic anorexia, often scolded by their parents for poor appetite or pampering during meals.
Appetite in children may be temporarily reduced, which is most likely due to the quality of food, lack of fluid in the hot season, monotony of food, etc.
Long-term impairment of appetite ( hyporexia ) up to its complete disappearance ( anorexia ) in children can cause:
- acute and chronic diseases;
- diseases of the digestive system;
- diseases of the nervous system;
- endocrine diseases;
- intoxication and poisoning;
- liver disease;
- cardiovascular disorders;
- the use of certain drugs, etc.d.
In infants, impaired appetite is often associated with conditions that make sucking difficult:
- birth trauma;
- otitis media;
- lesions of the central nervous system;
- diseases of the oral mucosa.
Young children suffer from appetite disorders due to overfeeding, force feeding, consumption of fatty and high-calorie foods.
Loss of appetite in children on psychogenic grounds can be accompanied by abdominal pain and vomiting, which leads to refusal to eat, weight loss and frightens parents who are unsuccessfully trying to feed the baby. Against the background of such a violation of appetite, children may even experience stuttering, bedwetting and other negative consequences. Some children refuse solid food for a long time and suffer from eating fears.
Decreased appetite in older children often occurs due to constant snacking and eating sweets between meals.School-aged children may suffer from neurogenic anorexia, accompanied by amenorrhea and emaciation. This is due, as a rule, to hormonal and endocrine changes in the child’s body, growth characteristics and environmental factors.
Adolescents (mostly girls) may experience mental (nervous) anorexia, expressed in restricting themselves in food or completely refusing to eat due to dissatisfaction with their figure, weight, etc.
Basically, with a loss of appetite in children, blood and urine tests , a coprogram are prescribed to exclude digestive pathology, infections, viruses, anemia.
Decreased appetite for any of the above reasons, causing weight loss, vomiting, worsening of the condition and accompanying symptoms can be dangerous to the health of a child at any age and requires specialist advice and an accurate diagnosis and subsequent treatment of the cause that caused your child’s appetite disorders.

The weaker sex is gaining weight
Women squeeze men a little
SPb.Enterprises in which the management of an equal number of men and women used to occupy their niche in the market and are more sustainable.
To such conclusions were drawn by experts from the Confederation of Swedish Entrepreneurship, summarizing data for all sectors of the Swedish economy over the past 5 years. “Equal the representation of men and women in the management of companies indicates that that the company has created optimal conditions for competition and supported the proper level of openness “, – explains the chairwoman of the confederation Tov Lifwendahl.Among the top managers of companies, about 20% are women, 30-40% are members of composition of the boards of directors. In Russia, this figure is 4 and 14%, respectively. (data from Pricewaterhouse Coopers).
Masculine and feminine
“The number of women who own small businesses is approximately the same in Russia and Sweden (about 25%), but the Swedes consider female representation in business as a strategy of socially oriented state “, – says Elena Kalinina, rector of the St. Petersburg socio-economic institute “, which promotes women in all spheres of society, including through the exchange of experience and information between women Russia and Scandinavia.Typically, a woman-owned business is initially socially oriented. “As a rule, women’s business is tourism, consulting, educational services, services related to quality leisure, cultural exchange. That is, women occupy niches that improve quality of life and create conditions for human development “, – summarizes Elena Kalinina.
In Sweden, the question of whether the state can legislate quotas is being discussed for women in companies in order to increase their representation.Tov Lifwendahl believes that this will be state intervention in the economy and accordingly, limiting free competition.
Anna Kenning, MP Swedish parliament from the Social Democratic Party, also considers the intervention state superfluous. “Women should unite and strive representation in legislative bodies, then their interests will be taken into account “, – she is convinced.
Elena Kalinina, rector of the St. Petersburg socio-economic institution “:” The Swedish welfare model is based on balance of interests of men and women in politics and economics.Russians should take a closer look at this experience. ”

Hypotrophy in children is a lack of mass associated with a lack or impaired absorption of nutrients in the body.From 2 to 30% of cases of pathology are diagnosed annually.
Classification and clinical symptoms
By the time of development, malnutrition is classified into intrauterine and extrauterine. In terms of severity, there are three degrees of pathology:
hypotrophy of 1 degree in children – lack of weight up to 10-20% of the norm. Babies develop by age, the decrease in appetite is insignificant. The skin is pale, the fatty layer is thinned;
hypotrophy of the 2nd degree in children – weight loss by 20-30% and growth retardation by 2-3 cm.Disrupted activity, poor appetite. Skin turgor and muscle tone are sharply reduced, the fat layer is absent on the body and limbs;
3 degree of malnutrition in children – underweight by 30% or more, a pronounced lag in development and growth. Adynamism, sharpness of facial features, dryness, dullness of the skin and mucous membranes, atrophy of muscles and tissues, disorder of the work of internal organs are noted. There is no subcutaneous fat. Complications develop: conjunctivitis, pneumonia, anemia.The condition is serious.
Causes of malnutrition in children
Hypotrophy in young children occurs under the influence of external and internal causes.
Internal causes are various diseases: fermentopathies, malformations, immunodeficiencies.
External causes are associated with three factors:
alimentary: with unbalanced / insufficient nutrition – breast milk deficiency, frequent regurgitation, diseases (birth injuries, cleft lip, cerebral palsy, etc.), fasting;
infectious, associated with ARVI and other infections;
social – poor living conditions.
Diagnosis and treatment of malnutrition in children
Congenital pathology is detected by ultrasound diagnostics. Acquired hypotrophia in children under one year of age and older is diagnosed during examination, changes in anthropometric parameters, and is confirmed by in-depth examination.
The approach to treatment depends on the reasons. The alimentary factor is corrected by the diet: by optimizing nutrition in terms of quality, nutritional and vitamin-mineral composition, and calorie content. Medical treatment – only on the recommendation of a doctor.
It is obligatory to control the dynamics of growth and body weight. The best assistant for mom is AGU Wally high-precision smart scales with monitoring of baby’s weight and height in a mobile application, helping to avoid hypotrophy and paratrophy.
Prevention of malnutrition in children includes quality nutrition and treatment of concomitant diseases.
AdaBoost Algorithm / OTUS Blog / HabrTranslation of the article was prepared on the eve of the start of the advanced course “Mathematics for Data Science”.
The AdaBoost algorithm can be used to improve the performance of any machine learning algorithm. Machine learning has become a powerful tool for making predictions based on large amounts of data.It has become so popular today that applications withmachine learning
find use even in everyday tasks. One of the most common examples is product recommendations based on past purchases made by a customer. Machine learning, often called predictive analysis or predictive modeling, can be defined as the ability of computers to learn without explicit programming. Machine learning uses ready-made algorithms for analyzing input data in order to make predictions according to certain criteria.
What is the AdaBoost algorithm?
In machine learning, boosting is needed to transform weak classifiers into strong ones. A weak training algorithm or classifier is a training algorithm that works better than random guessing, and it will work well in case of overfitting, because with a large set of weak classifiers, any weak classifier will perform better than a random sample. As a weak classifier, the usual
is often used for a certain criterion.If a feature lies above the
(threshold value) than it was predicted, it belongs to the positive area, otherwise – to the negative one.
AdaBoost stands for Adaptive Boosting or adaptive boosting. It turns weak learning algorithms into strong ones for solving classification problems.
The final classification equation may look like this:
Here f m is the mth weak classifier, where m is responsible for the corresponding weight.
How does the AdaBoost algorithm work?
AdaBoost can be used to improve the performance of machine learning algorithms
. It works best with weak training algorithms, so such models can achieve much higher than random accuracy when solving a classification problem. The most common algorithms used with AdaBoost aresibling decision trees
. A weak training algorithm is a classifier or prediction algorithm that performs relatively poorly in terms of accuracy.In addition, we can say that weak classifiers are easy to compute, so many entities of the algorithm can be combined to create a stronger classifier using boosting.
If we have a dataset in which n is the number of points and
Where -1 will be negative class and 1 will be positive. Then the weight of each point will be initialized as shown below:
Each m in the next expression will change from 1 to M.
The first step is to select the weak classifier with the lowest weighted classification error by applying the classifier to the dataset.
Then calculate the weight of the m-th weak classifier, as shown below:
The weight is positive for any classifier with an accuracy greater than 50%. The more weight, the more accurate the classifier. The weight becomes negative when the accuracy falls below 50%. The predictions can be combined by inverting the sign. Thus, a classifier with an accuracy of 40% can be converted into a classifier with an accuracy of 60%.This way the classifier will contribute to the final prediction, even if it performed worse than the random guess. However, the final result will not change in any way under the influence of the classifier, the accuracy of which is 50%.
The exponent in the numerator will always be greater than 1 in case of incorrect classification from the classifier with positive weight. After iteration, the weight of the misclassified objects will increase. Negative classifiers will behave in a similar manner. There is a difference here in the inversion of the sign: the correct classification will become incorrect.The final forecast can be calculated by taking into account the contribution of each classifier and calculating the sum of their weighted forecasts.
The weight for each point will be updated as follows:
Here Z m is the normalizing parameter. It is needed to make sure that the sum of all weights in an instance is 1.
Where is the AdaBoost algorithm used?
AdaBoost can be used for face recognition as it is the standard algorithm for such tasks.It uses a rejection cascade consisting of several layers of classifiers. When the recognition area does not detect faces on any layer, it is discarded. The first classifier in the area discards the negative area to keep the computation cost to a minimum. Although AdaBoost is used to combine weak classifiers, AdaBoost principles are also used to find the best features for each layer in the cascade.
Advantages and disadvantages of the AdaBoost algorithm
One of the many advantages of the AdaBoost algorithm is that it is easy, fast, and simple to program.In addition, it is flexible enough to combine with any machine learning algorithm without tuning parameters, except for the parameter T. It is extensible to learning problems more complex than binary classification, and is quite versatile because it can be used with numeric or text data.
Also in AdaBoost there are several drawbacks, at least that this algorithm is proved empirically and is very vulnerable to uniformly distributed noise. Weak classifiers, if too weak, can lead to poor results and overfitting.
AdaBoost Algorithm Example
As an example, let’s take a university admissions campaign, where an applicant can either be admitted to a university or not. Here you can take a variety of quantitative and qualitative data. For example, the outcome of an admission, which can be expressed as “yes” or “no,” can be quantified, while the skills and hobbies of students can be quantified. We can easily come up with the correct classification of the training data. For example, if a student has shown himself well in a certain discipline, then he will be more likely to be accepted.However, prediction with high accuracy is difficult and this is where weak classifiers help.
AdaBoost helps you select a training set for each classifier that is trained based on the performance of the previous classifier.
