لا تلقوا بلائمة السلوك الاجتماعي للمراهقين على الهرمونات

كان الاعتقاد يسود على نطاق واسع بأن ما يطرأ على السلوك الاجتماعي للفرد من تغيـُّـرات خلال مرحلة المراهقة إنما يعزى إلى الهرمونات التناسلية التي تتطور لديه عــنـد وصوله لسن البلوغ، إلاّ أنه بحسب دراسة أجراها الباحث “Matthew Paul“، الأستاذ المساعد في قسم عـِلـْم النفس بجامعة “Buffalo“، وزملاءه على قوارض “الهامستر“، يبدو أن تلك الهرمونات ليست بمسئولة عن تلك التغيـُّـرات الاجتماعية التي تطرأ أثناء فترة المراهقة، والتي يأتي على رأسها ظهور اضطرابات نفسية، وانتقال محور العلاقات الاجتماعية من محيط الأسرة إلى محيط الأقران، والميل إلى السلوكيات الخطرة.

 

وعلى الرغم من صعوبة فض التشابك ما بين التغيـُّـرات الاجتماعية التي تظهر خلال فترة المراهقة ويكون سببها الوصول لسن البلوغ وتلك التي لا تعزى إلى الوصول إلى سـنّ البلوغ، وذلك لأن البلوغ والمراهقة يحدثان في وقت متزامن، إلاّ أن الباحثين قـدّ وجدوا سبيلا للفصل بين الاثنين في تجربة قاموا بإجرائها على قوارض “الهامستر السيبرية” .

 

ففي هذه التجربة تمكن الباحثين من الــفــصـل بين مجموعتين مختلفتين من حيث توقيت الوصول إلى سـنّ البلوغ، ودرسوا مرحلة الانتقال من سلوكيات اللعب إلى سلوكيات الهيمنة الاجتماعية، ووجدوا أن هذا الانتقال يظهر في نفس التوقيت تمامـًا لدى كلتا المجموعتين بـِغـَضّ النظر عن موعد وصولهم إلى سـنّ البلوغ، وبتطبيق النتائج على كائنات أخـرى من بينها البشر، خلص الباحثين إلى أنه ليس ثـَـمَّـة علاقة بين هرمونات البلوغ والتغيـُّـرات الاجتماعية التي تشهدها فترة المراهقة.

    Our tear trough filler treatments target your under-eye area to help restore lost volume and make you look younger. With a regular treatment schedule — visits every 9-12 months — you can keep your eyes looking younger for longer! Kendall Peterson 1334 N Whitman Ln, Suite #200Liberty Lake, WA 99019 The treatment usually takes less than 15 minutes and you can see an initial result from the tear trough fillers immediately. Often the treatment causes a very subtle swelling, so although the area will instantly look more filled, we advise waiting a week to see the final result of the treatment. If you have a pigment problem with your under-eyes as well as a tear trough deficiency you will need a bespoke skincare regime to reduce this pigmentation too. In this case you’ll see an instant improvement from the fillers (which will improve shadowing and thin skin issues), but it will take several weeks to improve the pigment issue.

  • Engage, Learn and Measure with Orbit’s Immersive Learning Platform Investments in cryptocurrency have seen an astronomical rise over the last decade.  This rise has been fueled by the growing acceptance of cryptocurrencies, like Bitcoin and Ether, among mainstream investors and companies, such as Tesla Inc., Mastercard Inc., and BNY Mellon.  Bitcoin has also been deemed legal tender by at least one country, and others are likely to follow.    Crypto Cup Kickoff In the digital asset world, custody is often used in the sense of safekeeping, without including the additional services that traditional bank custodians provide to clients. Given the sensitivity and importance of the crypto wallet private key and the numerous reported hacks and thefts of coins, this aspect of the value chain is of great strategic importance to the development of the industry. There are two main methods of safekeeping:

    BTC Mining Revenue Tanks; Magic Eden Introduces Code to Enforce Creator Royalties If we have cash, we need a place under the mattress. If we have electronic money, we must have a service account. If we have online banking, we must have a bank account. In the case of cryptocurrency, you also need to create a place to store it. Now I will show you 3 ways. The first one is difficult but safe. The second is simple and insecure. The third is simple and secure, but paid. Everything is like in life: you can’t eat candy and lose weight. Like minting of physical coins back in the days when we used to back up our money with collateral, the same principle operates when minting stablecoins on BSC. BSC projects like Venus or QIAN are crypto-backed stablecoins that use BTCB as collateral to issue more stablecoins. Your BTCB is used to give value to freshly minted stablecoins, and you’re rewarded with earnings.

  • Prolonged exposure to hallucinogens can expose the user to experiencing flashbacks. A flashback is when the person abusing hallucinogens goes through a trip after the effects of the drug have worn off. This can occur months or even years after the addict has stopped using the drug. In addition, someone who has been using hallucinogens for a long period of time can experience diarrhea and chills if usage is abruptly stopped. He was admitted to a psychiatric hospital at the age of forty-eight years old where the admitting doctor described his symptoms as visual hallucinations and started him on Risperidone, which increased the intensity of his symptoms. He was also treated with Citalopram for his low mood. It was noted that his symptoms were different from common psychotic illnesses. Detailed history taking and assessment of his perceptual abnormalities over the following few weeks in hospital confirmed the diagnosis of hallucinogen persisting perception disorder (HPPD).

  • It wasn’t meant to be like this for Jack Wilshere. The former Arsenal and England midfielder has decided to call time on a playing career that saw him make 182 Premier League appearances and earn 34 caps for his country. Wilshere managed just three appearances across the 2015/16 season and while he did feature more prominently in 2017/18, making 35 appearances in all competitions for Arsenal following a successful loan spell with Bournemouth in 2016/17, it proved to be his last at the Emirates Stadium. UK: Boris Johnson’s successor to be named in September His post-Arsenal tenure was unfortunately beset by inconsistency after injuries continued to mount. After three seasons and only 16 appearances with West Ham, Wilshere’s contract was terminated in 2020 before a brief return stint with Bournemouth that ended in 2021. Since then, Wilshere has been a regular presence around the club training grounds during recent years as he continued to train with the first team in hopes of rekindling his career.

Everton manager Frank Lampard opting to bring Niclas Fullkrug to Goodison Park would be a ‘risky’ move, according to journalist Dean Jones. After leaving the academy setup in Anderlecht at 18, Kiwior made 76 appearances in Slovakia playing for FK Zeleziarne Podbrezova and MSK Zilina, scoring five goals and grabbing seven assists from 77 senior appearances (according to Transfermarkt). The fact Everton should save more than £25m annually when Fabian Delph, Gylfi Sigurdsson and Cenk Tosun’s contracts expire shortly only highlights the bad decision-making the club are now aiming to put behind them.

Click the “Download Now” button to start. You’ll be taken to Intertops Poker website to download the poker software and create your new account. Our awards and certificates of trust from global affiliate communities (clickable). Our team identified some complaints lodged against Intertops publicly, but they were mostly debunked by other players, either current or someone who used to play at Intertops Poker. In one instance, a player explained that Intertops had failed to honor a cryptocurrency payout. When you have chosen Intertops Poker, you may have thought that it would not be one of the best places to experience online poker, but as it turns out it is. Because of also being an online casino and offering sports betting products, you will see a lot of unexperienced players compared to other sites that offer only poker. This is one of the main reasons why i would recommend you to try out this online poker site.

  • Now we’ve learned all the poker hands, their description, and their ranking. Here is a copy of all poker hands from best to worst. The scoring in poker is based on a specific ranking of certain hand possibilities and determining which player’s hand holds the highest rank. Two cards of a matching rank and another two cards of a different matching rank, as well as one side card. If there is a tie at the poker table, the highest pair wins. If players have the same highest pair, the highest second pair wins. But, if both players have two identical pairs, the highest side card wins. Finally, the pair hand rounds up our list of the best hands in poker. Evidently, the pair hand consists of 2 cards of the same value. For instance, if you’re holding 2 Tens, you’ve got yourself a pair. Additionally, since this hand is much less specific than the previous ones, you’ve got a 1 in 1.3 chance of getting it, so it’s almost always!
