Itb Syndrome

My condition 3is called ITB syndrome Explanation: ITB syndrome stands for Iliotibial Band Syndrome. This is a common thigh injury generally associated with running. The band is crucial to stabilizing the knee during running. The irritation usually occurs over the outside of the knee joint, at the lateral epicondyle. The iliotibial band crosses bone and muscle at this point; between these structures is a bursa, which should facilitate a smooth, gliding motion. However, when inflamed, the iliotibial band does not glide easily, and pain associated with movement is the result. SymptomsITBS symptoms range from a stinging sensation just above the knee joint (on the outside of the knee or along the entire length of the iliotibial band) to swelling or thickening of the tissue at the point where the band moves over the femur. The pain may not occur immediately during activity, but may intensify over time, especially as the foot strikes the ground. Pain might persist after activity. Pain may a lso be present above and below the knee, where the ITB actually attaches to the tibia. Who does this commonly affect? Endurance athletes are prone to developing iliotibial band syndrome.Athletes who suddenly increase their level of activity, such as runners who increase their mileage, often develop iliotibial band syndrome. But other activities that can cause this are biking, hiking or weightlifting (especially when doing squats). Treatment The iliotibial band can be rested, iced and compressed to reduce pain and inflammation, followed by stretching. Using a foam roller to loosen the iliotibial band can help prevent and treat ITBS. A compression wrap to mobilize the ITB where the tendon meets the knee is also key to reduce the inflammation.Another pain reliever would be a cortisone injection into the area, which is usually helpful, and it can also be curative. But for the more severe and treatment-resistant cases may require surgery to mobilize the band. Prevention Rolling out your IT band will help prevent this. While this exercise using a foam roller will help to alleviate IT band pain, it also helps prevent problems from starting in the first place. It's painful, especially if you're already having IT band issues, but after a week or two of consistent rolling, you'll notice less pain. Also a lot of stretching can prevent ITB syndrome.

Profile of Idaho Teen Killer Sarah Johnson

Profile of Idaho Teen Killer Sarah Johnson Sarah Johnson was 16 years old when she shot and killed her parents with a high-powered rifle because they did not approve of her 19-year-old boyfriend. Victims Alan, 46, and Diane Johnson, 52, lived in an attractive home that sat on two acres of land in an affluent suburb in the small community of Bellevue, Idaho. They had been married for 20 years and were devoted to each other and their two children, Matt and Sarah. The Johnsons were well liked in the community. Alan was the co-owner of a popular landscaping company, and Diane worked for a financial firm. The Crime In the early morning hours of September 2, 2003, Sarah Johnson ran out of her home, screaming for help. She told neighbors that her parents had just been murdered. When police arrived, they found Diane Johnson lying under the covers of her bed, dead from a shotgun blast that had removed most of her head. Alan Johnson was found lying next to the bed, dead from a gunshot wound to his chest. The shower was running, and Alan’s body was wet. Based on wet, bloody footprints and blood splatters, it appeared that he had stepped out of the shower and was then shot, but managed to walk towards Diane before collapsing and bleeding to death. The Crime Scene The police immediately secured the crime scene including sectioning off an entire block around the house. In a trashcan outside of the Johnson’s home, investigators found a bloody pink bathrobe and two gloves. One was a left-handed leather glove, and the other was a right-handed latex glove. Inside the home detectives found a trail of blood spatters, tissue and bone fragments that went from the Johnson’s bedroom, into the hall, and across to Sarah Johnson’s bedroom. A .264 Winchester Magnum rifle was found in the master bedroom. Two butcher knives, with the tips of the blades touching, had been placed on the end of the Johnson’s bed. A magazine of bullets was also found in Sarah’s bedroom, which was located around 20 feet across the hall from the Johnsons bedroom. There was no evidence of forced entry into the home. Sarah Johnson Talks to Police When Sarah Johnson first talked to the police, she said that she woke up around 6:15 a.m. and heard her parents shower running. She continued to lie in bed but then heard two gunshots. Sarah Johnson ran to her parent’s bedroom and found that their door was closed. She did not open the door, but rather called for her mother who did not answer. Frightened, she ran out of the house and began screaming for help. The Story Changes Her story of what happened would change several times throughout the investigation. Sometimes she said her parent’s door was slightly opened and other times she said her door was closed, but not her parent’s door. Based on the forensic evidence found in the hall and Sarah’s bedroom, both her door and her parent’s door would have to have been opened. Sarah also admitted that the pink robe was hers, but denied knowing anything about how it ended up in the trash. When first asked about the robe her first response was to say that she did not kill her parents, which investigators found odd. She said she thought the killer was a maid who had been recently fired by the Johnsons for stealing. The Murder Weapon The owner of the rifle used to kill the Johnsons belonged to Mel Speegle, who was renting a garage apartment in a guesthouse located on the Johnson’s property. He was away over the Labor Day weekend and had not yet returned home on the day of the murders. When questioned, he told police that the rifle was kept in an unlocked closet in his apartment. Infatuation and Obsession Sarah Johnson was described by neighbors and friends as a sweet girl who enjoyed playing volleyball. But another Sarah had emerged over the summer months. One that seemed infatuated and obsessed with her 19-year-old boyfriend, Bruno Santos Dominguez. Sarah and Dominguez had been dating for three months before the murder of her parents. The Johnsons did not approve of the relationship because Dominguez was 19 and an undocumented Mexican immigrant. He also had a reputation for being involved in drugs. Close friends of Sarah’s said that a few days before the Johnson’s murder, Sarah showed them a ring and told them that she and Dominguez were engaged. They also said that Sarah often lied, so they did not completely buy into what Sarah was saying about her engagement. Days Leading up to the Murder On August 29, Sarah told her parents that she was spending the night with friends, but instead, she spent the night with Dominguez. When her parents found out, her father went to look for her the next day and found her with Bruno at his family’s apartment. Sarah and her parents argued, and Sarah told them about her engagement. Diane was very upset and said that she was going to go to the authorities and report Dominguez for statutory rape. If nothing else, she hoped to have him deported. They also grounded Sarah for the rest of the Labor Day weekend and took her car keys. During the following days Sarah, who had a key to Speegle’s apartment, was in and out of the guesthouse for various reasons. Both Diane and Sarah called Matt Johnson, who was away at college, on the night before the murders. Matt said his mother cried about Sarahs relationship with Dominguez and expressed how embarrassed she felt by Sarahs actions. Uncharacteristically, Sarah seemed to accept her parents punishment and told Matt that she knew what they were up to. Matt did not like how the comment sounded and almost called his mother back, but decided not to because it was so late. The next day the Johnsons were dead. DNA Evidence DNA testing showed that blood and tissue belonged to Diane on Sarah’s pink robe, along with DNA that matched Sarah. Gunshot residue was found on the leather glove, and Sarah’s DNA was found inside of the latex glove. Diane’s DNA was also found in the blood that was on the socks Sarah was wearing on the morning her parents were killed. Sarah Johnson is Arrested On October 29, 2003, Sarah Johnson was arrested and charged as an adult on two counts of first-degree murder to which she pleaded not guilty. Nancy Grace Helped Prosecutors One of the big problems that the prosecution had with a major piece of evidence had to do with the pattern of blood splatters found on the pink robe. Most of the blood was on the left sleeve and the back of the robe. If Sarah put the robe on before shooting her parents, how did so much blood get on the back? While the prosecution was struggling to put together a viable explanation for the location of the blood on the robe, Sarahs defense lawyer, Bob Pangburn happened to appear as a guest on the Nancy Grace Current Affairs program. Nancy Grace asked Pangburn about the blood on the robe, and he said it showed possible contamination of evidence and that it actually could help exonerate Sarah Johnson. Nancy Grace offered another explanation. She suggested that if Sarah wanted to protect her body and clothing from blood splatter, that she could have put the robe on backward. Doing that would act as a shield, and the blood would then end up on the back of the robe. Rod Englert and other members of the prosecution team happened to be watching the program, and Graces theory provided them with a reasonable scenario that would result in the blood patterns that were on the robe. Court Testimony During the trial, there was a lot of testimony about Sarah Johnson’s inappropriate behavior and lack of emotions about the brutal murder of her parents. Neighbors and friends who offered comfort to Sarah on the day her parents were killed said that she was more concerned about seeing her boyfriend. She also did not seem traumatized, which would be expected if a teen went through the experience that she had inside the house when her parents were gunned down. At her parents funeral, she talked about wanting to play volleyball that evening and any sadness that she displayed seemed superficial. Witnesses also testified about the troubled relationship between Sarah and her mother, but many also added that it was not that unusual for a girl her age to fight with their mother. However, her half-brother, Matt Johnson, gave some of the most insightful testimony about Sarah, although it also proved to be some of the most damaging. Johnson described her as a drama queen and a good actor who had the propensity to lie. During part of his two-hour testimony, he said that the first thing Sarah told him when he arrived at their home after finding out his parent’s had been murdered, was that the police thought that she did it. He told her he thought Dominguez did it, which she vehemently denied. She said that Dominguez loved Alan Johnson like a father. Matt knew this was not true. She also told him that at 2 a.m. on the night before the murders, that someone had been to the house. Her parents checked the yard to make sure no one was out there before they went back to bed. She had not provided this information to the police. Regardless Matt did not believe her but did not challenge what she was saying. In the weeks after the murders, Matt testified that he avoided asking his sister about the murders because he was afraid of what she might tell him. The "No Blood, No Guilt" Defense Some of the strongest points that Sarah’s defense team made during her trial had to do with the lack of biological matter found on Sarah or her clothing. Investigators found nothing in her hair, hands, or anywhere else. Experts testified that with Diane having been shot at such close range, it would be impossible for the shooter to avoid being sprayed with blood and tissue and yet none was found on Sarah who underwent two complete physical exams on the day of the murders. Her fingerprints were also not found on the bullets, rifle or the knives.  However, there was one unidentified print found on the rifle. The testimony of cellmates of Sarahs who testified about some of the damaging comments she made regarding the murders was challenged. One cellmate said that Sarah said the knives were placed on the bed to throw off the police and make it look like a gang-related shooting. The defense fought to have the testimonies thrown out because the cellmates were adults and the law forbids incarcerated minors to be housed with adults. The judge did not agree, stating that if Sarah could be tried as an adult, she could be housed with adult prisoners. The defense team also questioned Matt Johnson about the life insurance money he would get if Sarah were out of the picture, insinuating that he had a lot to gain if Sarah was found guilty. The Verdict and Sentencing The jury deliberated for 11 hours before finding Sarah Johnson guilty on two counts of murder in the first degree. She was sentenced to two fixed life prison terms, plus 15 years, without the possibility of parole. She was also fined $10,000, of which $5,000 was allocated to go to Matt Johnson. Appeals Efforts for a new trial were turned down in 2011. A hearing was granted for November 2012, based on the possibility that new DNA and fingerprint technology that was not available during Sarah Johnsons trial may prove that she is innocent. Attorney Dennis Benjamin and the Idaho Innocence Project took on her case pro bono in 2011. On February 18, 2014, the Idaho Supreme Court  rejected Johnsons appeal.

Free Essays on Same-Sex Marriage

Same-sex marriage By Serena Irani 16/01/05 The issue of same-sex marriage has been debated in the world for many years now. This topic concerns especially the three monotheistic religions: Judaism, Christianity and Islam. What is their personal opinion on this subject? Who is with and who is against? All religions view human sexuality as a potential source of sin. Non consensual sex, unsafe sex, manipulative sex are generally regarded as sinful. Many regard recreational sex as immoral, and teach that sex must be restricted to loving, monogamous committed couples. Some insist that it is only moral within a marriage. But faith groups differ in their beliefs about homosexuality. Some teach that these same rules apply to homosexuals and bisexuals as well as heterosexuals that sexual activity is not sinful if it is consensual, safe, non-manipulative, and within a committed relationship. Others teach that homosexuality is an intrinsically disordered, abnormal, chosen, and unnatural behavior, which is always sinful, regardless of t he nature of the relationship between the participants. For Jewish communities, there are two primary questions. First, should they legalize same-sex marriage, offering homosexual couples the same legal benefits that married heterosexual couples have? Secondly, should rabbis perform same-sex Jewish weddings, and if so, can these ceremonies be considered kiddushin (the Hebrew term for holy unions)? This would give them the same status as heterosexual marriages. The four primary liberal Jewish denominations- Reform, Reconstructionist, Conservative and Orthodox- have been fighting with these questions for over a decade. The Reconstructionist movement expressed its support for the full inclusion of gay men and lesbians in all aspects of Jewish life in its 1992 Report of the Reconstructionist Commission on Homosexuality. The report affirmed the holiness of homosexual relationships and the need to affirm the... Free Essays on Same-Sex Marriage Free Essays on Same-Sex Marriage Marriage is the basis for procreation and child rearing, which in turn is the foundation of family and social life. There are indications that allowing polygamous or closely related couples into our marriage system would be dysfunctional in our society. This also applies to same-sex marriages. The social unacceptability of same-sex marriage, the danger of contracting AIDS, and the bad influence on children indicate that same-sex marriage should not be legalized. Homosexual activists, approximately three percent of our population, argue that those who do not agree with them are â€Å"homophobic.† However, that argument is merely prejudiced against society. Society is entitled to have its own opinion. The rights of homosexuals are undoubtedly restricted. Congress’s litigation now describes laws that prevent homosexuals from marrying or adopting. Marriage and adoption are considered a privilege. Those who marry or adopt must obey the laws. No examples in past history occur in which homosexual unions were given the equal rights and legal recognition as heterosexual unions. In a poll taken, American adults were asked if homosexual marriage should be legal; sixty-four percent stated no, while only twenty-nine percent said yes. The same group of adults was also asked about homosexual adoption. Fifty-seven percent said no, while thirty-five percent agreed. By broadening our systematic form of marriage, we weaken the institution as a w hole. Allowing a socially unacceptable union only weakens the bonds of society. The state’s main interest in marriage is to provide financial and emotional security, as well as role models for children. In the current marriage system of homosexual unity, the protection of procreation is properly emphasized. The symbolism of homosexual marriage affects all parties involved. For example, a lesbian or gay wedding has a heavy symbolic message on all guests that attend, including children, cooks, and waiters. Ge... Free Essays on Same-sex Marriage Same Sex Marriage†¦ Agree or disagree? The controversial subject of legalizing same sex marriage in each of the states is getting more and more attention in the legislature. While each state has it’s own determination on whether or not same sex marriages should be recognized, many states do not view a same sex marriage as a legal union. The unanswered question is weather same sex marriage should or should not be legalized. Jonathan Rauch, journalist for The Atlantic, believes that banning same-sex marriage is discriminatory. Marriage is a basic human right and should not be denied to any individual. At various times in U.S. history, other minorities have been prevented from marrying African-Americans for example. Interracial marriage was also legally prohibited in various states until the Supreme Court ruled such bans unconstitutional in 1967. (U.S News) Jonathan’s farther examination of marriage discrimination concluded that banning gay marriage cut same-sex couples off from a host of tangible advantages such as; health and retirement benefits, life insurance, income tax, estate tax, wrongful-death benefits, and spousal, dependent support. On the other hand, marriage benefits cost money. If same-sex marriage were legal gay couples would become eligible for federal benefits and tax breaks. Placing an additional burden on an already strained federal treasury. Taxpayers would end up subsidizing a lifestyle of which many disapprove. To address that issue, the bill introduced on Capitol Hill by Representative Bob Barr, a Georgia Republican, would allow states to ban gay marriage and make it clear that for federal purposes marriage means married heterosexual union. But supporters say that taxpayers benefit from same sex marriages. It puts legal force behind the promise to care for a loved one â€Å"in sickness and in health.† Homosexual partners bound by law to care for one another are less likely to ask for government assistance when...

How I Established My Romance Novels Subgenres

How I Established My Romance Novels Subgenres How I Established My Romance Novel's Subgenres Barbara James lives in New York, and is an avid romance reader and a former academic writer. In this article, she breaks down her latest romance novel's subgenres - sweet, contemporary, new adult - and explains the characteristics and importance of each one. How my novel is â€Å"new adult†New adult is for readers who have graduated from the young adult category, but who face different conflicts and questions than the rest of the 30+ adult group. They are still in the early stages of their lives, grappling with identity, relationships, and career.In Starting Over, Annelise is more conservative than most of her peers: she hopes to be married by the time she graduates university, and to become a stay-at-home mom by the time she’s in her mid-twenties. This is a more â€Å"old-fashioned† life plan than many people in their early-twenties have today, so Annelise struggles with how to fit in with her peers, and is constantly questioning her life plans and decisions.When my novel was finished and I was ready to start working with a professional editor, I knew I wanted someone who was a clear fan of the romance genre.Working with a development editor who also loves romance novelsA developmental editor can be instrumental in either helping you define your genre or tailoring your novel more to your chosen genre. And this was absolutely the case with my editor, Mary-Theresa Hussey. She worked for over 25 years as an executive editor at Harlequin, so she really knew her stuff. A developmental editor can be instrumental in helping you define your novel's genre. One way she challenged me fairly early on was with respect to age differences. Annelise could have been older, a graduate student, about 22–24 years old or Rick could have been younger, 24–25 years old. Ultimately, I made Rick ten years old, 28 to Annelise’s 18, because I wanted him to be ready to handle the responsibility of being the husband of a younger, stay-at-home-wife. But Mary-Theresa’s suggestion that I re-think their age difference helped me more firmly establish why the ten-year age gap was important to the story, strengthening each character in my mind.As her work history clearly suggests, Mary-Theresa is a fan of romance novels herself. Working with an editor who has a preference from romance novels was as important to me as their professional backgrounds, which is why I was so happy Reedsy permitted me to search for editors with specific keywords.Starting Over is available in paperback and on Amazon Kindle.Please share your thoughts, experien ces, or any questions for Barbara James in the comments below!

The Primary Shaper of Gender Differences Research Paper

The Primary Shaper of Gender Differences - Research Paper Example Recent studies demonstrate, however, that nurture is a powerful force in affecting so-called â€Å"genetic† or â€Å"natural† gender differences (Sameroff 8). This paper asks: Are gender differences primarily caused by nature or nurture? This paper believes that gender differences, in terms of risk-taking, aggression, cognitive abilities, and language skills, are significant products of nurture, which refers to a host of diverse environmental factors. Risk-taking is commonly believed to be a masculine trait, but sources show that it is the environment, and not genetics, which plays a large role in shaping risk-taking attitudes and behaviors. In â€Å"Gender Differences in Risk Behaviour: Does Nurture Matter?† Booth and Nolen examined if choosing risky outcomes is truly an innate preference reserved for boys. They hypothesized that single-sex settings for girls can enhance their risk-taking behaviors than co-ed settings and these behaviors will not differ from boy s. They recruited 260 students with an average age of 15 years old. The sampling came from Essex and Suffolk counties in the United Kingdom. The researchers used five rounds of lottery to determine risk-taking behaviors. Findings showed that gender differences in risk-taking preferences are affected by the school environment. In particular, girls from single-sex schools take the same risks as boys from co-ed and gender-exclusive schools and more than co-ed girls. Gender mix also affects risk-taking behaviors, where girls in all-girls groups take higher risks than those in mixed-sex groups. Booth and Nolen concluded that nurture variables had a significant impact on risk-taking behavior, where all-girls settings remove traditional gender influences on risk taking. Morrongiello, Zdzieborski, and Normand seek to provide an explanation for differences in risk-taking behaviors between men and women in their study, â€Å"Understanding Gender Differences in Children's Risk Taking and Inju ry.† They compared the reactions of mothers and fathers to their children’s risk-taking actions. Around 52 mother–father pairs participated, where their reactions to their sons and daughters were recorded before and after injuries. Findings showed differences in kinds and reasons of reactions; for instance, mothers were angry at their sons, while for their daughters, they showed disappointment and shock. The researchers quote psychologists Kessler et al: â€Å"†¦What is hegemonic at any given time depends on how the relations among different kinds of masculinity and femininity have been worked out† (17). Morrongiello, Zdzieborski, and Normand conclude that parents have gender-based perceptions, which affect their discipline approaches to their children regarding their risk-taking behaviors. The way they discipline their children, in turn, affects the existence of gender differences in terms of risk-taking. Nurture affects the genetic risks for aggress ion among men, which proves that the environment strongly brings about gender differences in aggressive personalities between men and women. Boutwell, Franklin, Barnes, and Beaver studied if genetic influences interact with the effects of spanking on children’s behaviors. They analyzed statistics from twin siblings that were gathered from a nationwide-survey. Findings showed that spanking can provoke aggression among children, especially for boys, when genetic risks are present. Boutwell et al. believe that boys are more predisposed to violence,

Technology paper ( mouse) Essay Example | Topics and Well Written Essays - 750 words

Technology paper ( mouse) - Essay Example Introduction Technological revolution and the use of computers systems have transformed human perception to almost all operations and tasks. Living in the midst of technological harbor, several changes have been envisaged with the use of computer application, which transforms the society into a digital hub leading to sustainable economy. The use of computer systems has facilitated management, communication, data processing and information security but all these has been made even much easier with an aid of a computer mouse, which is classified as a computer point and draw device [Salvendy,2001,p. 36]. The mouse innovation According to SpringerLink, 2011, p. [1236], the earliest forms of computers such as the electronic numerical integrators or the main frames never used the mouse technology. This is because their applications were based on command prompt, which only required typing in commands to execute an instruction. However, with the introduction of windows in 1985, a mouse was d eveloped to assist in the maneuvering around the computer different applications. A mouse sizeable enough to fit the palm is made up of two buttons left and right with a trackball at the bottom. It is meant to detect two dimensional motions relative to the supporting surface. The mouse is meant to be physically beneath the palm with the two fingers resting on the buttons respectively. When the device moves on a surface, the user gets into a position to track, drag select and move files, icons or even folders. Moreover, a mouse allows the user to draw images and navigate almost all applications within a computer system. The first mouse was invented by Douglas Engelbart in 1968 after completing his research concerning studies about the human interpretation with computers. However, the official launch of this invention was put into public at Xerox Paulo research center in 1970 [SpringerLink, 2011.p. 1236]. Classifications of mouse Since the introduction of mouse into the market, there have been several classifications based on technology, mode of operation and usage. The most common type of mouse in the market includes: Mechanical mouse This type of mouse uses a ball to move the cursor on the surface of the screen. In order to enjoy the best efficacies, a flat pad would be needed to enable the rubber ball which is contained beneath to roll easily. The rolling ball would triggers the movement of the cursor on to the surface, which further translates into information understood by the computer system [SpringerLink, 2011, p 1236]. Optical mouse Optical mouse uses the sense of lesser rays to help detect the mouse movement in line with the arranged pixels on the surface where the movement is being made. The optical mouse uses red light emitting diode (LED) sensor to induce movement on the surfaces and send signals into the computer for interpretations. The red light emitting diode (LED) bounces the light off the surface onto the complementary metal-oxide semiconductor (CMOS). This mouse offers, the most effective speed and can be used in almost all surfaces [SpringerLink, 2011, p. 1236]. Wireless mouse This type of mouse usually comes up with additional dongle that are attached to the USB ports. The mouse itself contains a Bluetooth transmitter, which sends signal to the dongle acting as the Bluetooth receiver. The signals would then be interpreted by the computer
