Dating of Bruises in Abuse, Child Abuse Petechiae Bruise Expert
Sitting in the Kingdom Hall as a young child, I would hear talks about sex, but they were, for the most part, warnings about what not to do—what was moral and what was not— but mostly not. Masturbation was wrong, mutual masturbation was wrong, and both oral and anal sex were wrong. So I promised myself that as soon I found out what the heck they were, I would never do them.
As I grew up, I came to understand what sex is really all about, according to Watchtower teachings. I also heard from the platform and from people at the Hall how it was not good for a man to be alone; that he needed a wife to satisfy his sexual needs.
Colour changes tend to begin at the margins of a bruise, and thus a large collection of blood will take comparatively longer to pass through a series of colour changes. Traditionally, opinion regarding the ‘age’ of a bruise was based in large part on the colour of the bruise, and authors of forensic textbooks gave their own suggested ‘timetable’ of colour changes with time summarised in Langlois and Gresham There appeared to be a ‘consensus’ view that red, blue and purple were ‘early’ colours, greens appearing after days and yellow making a late appearance after at least 7 days.
Yellow colouration appeared in bruises in calves, however, by 48 hours McCauseland and Dougherty However, it is now clear that the progressive colour changes do not occur in a ‘linear’ or predictable fashion, and researchers have attempted to identify what, if any, information can be gained from observing colour changes in bruises, and subsequently giving an opinion regarding their likely duration. A standard colour chart was included, and in some, but not all cases, repeat photographs were taken.
The key finding of this study was that yellow was not seen in bruises less than 18 hours old, but that not all bruises developed this colour before resolving, and so a bruise without yellow could not be said to be less than 18 hours old. They also indicated that the colours in bruises were dynamic, and could ‘reappear’ days later, and that separate bruises on the same person, inflicted at the same time did not necessarily exhibit the same colours, nor undergo equivalent changes in colours over time.
Skin colouration affected the evaluation of bruising, and the study findings were therefore limited to white skinned individuals.

These are particularly common amongst African or Asian children, and are merely congenital marks on the back, shoulders, shins or ankles etc, and which are often dark blue or violet in colour. Bruising in abused children There is no difference between patterns of bruising in boys or girls Johnson and Showers Bruises are larger in abused children, and they have more bruises Atwal et al ; Dunstan et al Bruising is most common on the head, but any part of the body is vulnerable – in particular other sites commonly found to be bruised include the ear, face, neck, trunk, buttocks and arms.
Where bruising is absent, Atwal et al speculated that this was due to an insufficient degree of force being applied, gripping being cushioned by clothing, or the disappearance of the bruising by the time of autopsy. Bruising found on those with fatal head injuries is primarily found on the head and face, with lesser amounts on the lower limbs and the buttocks. Clusters of bruises are common – often defensive injuries on the upper arm, outside of the thigh or bruises on the trunk and adjacent limb.

A theory that can explain this finding from an evolutionary perspective is the parasite-stress theory which explains that an increase of infectious disease can cause humans to evolve selectively according to these pressures. Evidence also shows that as disease risk gets higher, it puts a level of stress on mating selection and increases the use of polygamy. In regions such as Sub-Saharan Africa the use of polygyny is commonly practiced as a consequence of high sex-ratios more males born per females and passing on heterozygous diverse genetics from different females to offspring.

Chris Brown Looks like this beauty queen may be less innocent than she makes out. Since it emerged that Chris Brown had been arrested and charged with assault with a deadly weapon after a beauty queen named Baylee Curran accused him of pointing a gun at her during a party on earlier this week, various stories have surfaced suggesting that the woman may not be as squeaky clean as she is purporting to be.
Did Chris Brown’s accuser lie about the whole thing? Baylee says that she was thrown out of Chris Brown’s party after innocently admiring a diamond crucifix that his friend had been displaying. According to her, the friend went crazy on her despite the fact that she didn’t even touch the jewellery, which prompted Chris to react by pulling out his firearm and aiming it at her. It resulted in a short stand-off between Chris and his entourage and the police when he refused to leave his house before the arrival of his lawyer Mark Geragos.
Chris’ party deny any wrongdoing. Tmz have been doing some digging, though, and it seems what Baylee originally told them may not be the full story.

Paleomagnetic dating[ edit ] A sequence of paleomagnetic poles usually called virtual geomagnetic poles , which are already well defined in age, constitutes an apparent polar wander path APWP. Such path is constructed for a large continental block. APWPs for different continents can be used as a reference for newly obtained poles for the rocks with unknown age. For paleomagnetic dating it is suggested to use the APWP in order to date a pole obtained from rocks or sediments of unknown age by linking the paleopole to the nearest point on the APWP.
Two methods of paleomagnetic dating have been suggested 1 Angular method and 2 Rotation method.

As it is, men between 22 and 30 — nearly two-thirds of the male dating pool — focus almost exclusively on women younger than themselves. Because it has been a successful way to introduce previous posts, I wanted to put real faces on this demographic before I delve into a bunch of numbers. Pictured below are some single users in their mid-thirties or early forties, taken from the first couple pages of my own local match search.
As you can see below, the number of online daters peaks at 24, drops sharply at around 30, and then gradually tapers off, as the remaining singletons either find mates or withdraw themselves from contention: The bar chart here shows how the woman to man ratio changes over time. Of course, we all know that 45 year-olds do have a much harder time, because the male fixation on youth distorts the dating pool.
Look at how men have set their age preferences on OkCupid: As you can see, a man, as he gets older, searches for relatively younger and younger women. Meanwhile his upper acceptable limit hovers only a token amount above his own age. The median 31 year-old guy, for example, sets his allowable match age range from 22 to 35 — nine years younger, but only four years older, than himself.

The blood collected in the soft tissues beneath the skin shows up as the discolored patches that are associated with bruising. Sometimes the pooled blood move down under the effect of gravity making the bruise to spread downwards accordingly during the different stages of bruising and healing. Eventually the body reabsorbs the leaked blood gradually until the bruise goes away at some stage of bruising. Reabsorption involves the metabolism of the different components of the blood.
As the contents of the blood collected under the skin changes with the metabolism of different components, the color of the bruises change accordingly until the bruise finally disappears. Stages of Bruising Colors A bruise goes through a sequence of color changes from the time it is formed to the time it finally heals. Understanding and observing the color of a bruise can help identify how old a bruise is and how close it is to full healing. Let us now break down the various stages of bruising colors so to speak: Red At their onset, bruised look red or pink in color because of the presence of iron-rich hemoglobin in the pooled blood.
The area around the bruise may also get tender and swollen. Dark blue or purple Within one to two days from the time of injury or trauma, the bruise will then turn its color to dark blue or purple. This will continue through to the fifth day. It is attributed to low oxygen supply in the site of bruising as a result of swelling, which then causes the normally red hemoglobin to change its color accordingly.
