Choose to Reuse

The aim of our project was to reduce the waste of coffee cups on campus. Only 1/1000 takeaway coffee cups get recycled due to a difficult recycling process. With over 8,000,000 of these cups used every day in the UK alone; this has lead to an enormous amount of unnecessary waste.

To start our project, we emailed Warwick retail to see how many coffee cups are actually used on campus. They responded that 4500 cups are used each week in university run cafes.

After receiving this information we asked over 200 students in the library the following questions:

1. Is the environment important to you?
2. Are disposable coffee cups recycled? We then explained only 1/1000 coffee cups are actually recycled
3. Would you consider bringing your own travel mug if you were charged for a takeaway cup? We then informed them that in university run cafes they are in fact charged 10p for the use of a takeaway cup.

Here are the results:

After collecting this data we decided to make an Instagram account to inform people about the lack of recycling on campus and encourage them to use travel mugs.

We created and posted infographics as a visual aid to display some of the consequences of coffee cup waste. We used natural frequencies to persuade people to reduce waste and use a travel mug.
In addition, we encouraged people to post selfies with travel mugs on their personal instagram accounts and we also shared the ones we were aware of on our instagram page. Our captions either generally encouraged people to #choosetoreuse, framed the 10p price difference for using a travel mug in campus cafes as a charge or emphasised that other people were making the decision to use a travel mug (social proof).
The instagram page was shared on other social media sites and was also circulated within societies of the university to try to reach a wider audience.

We got in touch with Emily Grieve, the president of Her Campus society at Warwick. Her Campus is the #1 global community for college women, written entirely by the nation’a top college journalists from 300+ Universities around the world. We were interviewed about our project and an article was posted on the Her Campus website. Here is the link to the article:http://www.hercampus.com/school/warwick/warwick-choosing-reuse

Overall, our Instagram page gained over 300 followers and posts were seen by more than 500 people on other media sites. In addition, at least 30 students posted photos of themselves using travel mugs to their social media pages. Therefore, we believe that our message to reduce coffee cup waste on campus reached 1000 individuals. Furthermore, we have spoken to students who said they’ve changed their behaviour and bought a travel mug since the campaign!

Why do some men rape? Understanding the psychology of rapists

In humans, females have greater reproductive certainty than males. This means that while most females will eventually reproduce, a lot of men are can be entirely excluded from reproducing.

Also, since human females can produce a limited number of eggs and invest much more in their offspring than males, they’re a reproductively valuable resource.

The result is that there’s usually fierce intrasexual competition among men for women and men are predisposed to be aggressive, eager to mate, and less discriminating in choosing mates. (see Why men have a stronger sex drive than women)

Now, men of higher mate value who have resources and are attractive can achieve reproduction by means of attraction with willing women but what about men of lower mate value?

Men of low mate value who lack resources and are unattractive have extra psychological pressure to achieve reproduction whenever they can and so may resort to sexual aggression and rape in a desperate attempt to pass on their genes.

This is why a huge proportion of rapists tend to be poor and ugly, having a low facial symmetry which indicates poor genetic quality.

This, however, does not mean that only sexually deprived men of low mate value commit rape. In their quest for greater reproductive success, men who achieve mating through the means of attraction can also resort to sexually aggressive tactics in circumstances where costs are outweighed by the benefits.

Take war for example. Rape is common during wars because not only do the aggressing men eliminate other men who would otherwise guard their women, there’s no law and order that can hold them accountable for their actions during such times of chaos.

Another circumstance in which men, not necessarily of low mate value, can rape is when they come to know about or suspect their partner’s infidelity. Partner rapes, especially during a breakup, comprise a significant proportion of reported rapes.

Concerned by the possibility that some other man may have inseminated her partner, the man uses force to inseminate her so that he can win the sperm competition by beating the other man’s sperm to the egg.

Rape in nature

Humans are not the only animals in which sexual aggression and rape is observed. Although rape is a rarity in the animal kingdom, the males of species as diverse as insects, ducks and monkeys have been observed engaging in sexual coercion to force insemination.

In a male scorpionfly, for example, there’s an organ specifically designed to facilitate sexual access to a female in a coercive manner. It’s a type of hook on its wing that enables it to grip the female as it forces copulation.

Though all males in this species have this organ, they don’t all use it. Females of this species prefer to mate with males who bring them a nuptial gift (a dead insect as food). When a male fails to offer food, females aren’t interested in mating and that’s when the coercive technique is employed by the male.

Similarly, small orangutan males who’re unable to achieve copulation through intrasexual competition with other bigger males (small size is not good for intrasexual competition) chase and rape the females.

The white-throated bee-eater is a species of bird in which rapists are those individuals who, after breeding early in the season and raising young with a monogamous partner, embark on raping forays.

They chase any female who is still fertile and who has been left unguarded by a male and attempt to force insemination. Clearly, the males of this species are going for greater reproductive success.

Why Marriages Fail

Why do some marriages last and others fall apart?

This is a question that troubles countless people who may be worried about their parents divorcing, their spouse leaving them, or that an upcoming marriage won’t last. While there are no easy answers, Dr. John Gottman’s research can help shed light on this critical question.

As anybody in a relationship knows, sometimes major fights stem from seemingly insignificant interactions. Maybe one person bought the wrong milk at the store, failed to hang up a coat, or simply seemed distant in conversation. This can lead to a sharp criticism, spiraling into a significant conflict.

But why is it that these minor instances can explode in such a fashion? Often, they can just be the result of miscommunication or of a lack of understanding of the other’s feelings. The real problem, as Dr. Gottman describes it, arises when contempt enters the equation.

Contempt arises from unresolved negative thoughts about your spouse or the, perhaps subconscious, belief that you are superior. Often, these underlying feelings manifest themselves in the form of overly aggressive reactions, such as hostile humor, name-calling, or body language such as eye-rolling.

Not only do these reactions turn an otherwise minor conflict into an intractable war, but they also lead to more conflict down the line, making this behavior a leading cause of failed marriages. In fact, contempt can even lead to declined physical health, resulting in infectious illnesses like colds and the flu!

Dr. Gottman’s research, demonstrates just how dangerous these attitudes can be to the health of a relationship. While partnering with Berkeley psychologist Robert Levenson, the two researchers studied 79 Midwestern couples over the course of fourteen years. This 2002 study found that contempt, in addition to related behaviors, predicted divorce with 93 percent accuracy.

In a more recent study of 373 couples, Dr. Gottman found that acts of contempt and general disregard in the first year of marriage were strongly related to future divorces.

Given the acute danger of such underlying behaviors, it is especially critical to be mindful and aware of them. Dr. Gottman attempts to provide lessons that can reduce the catastrophic impact of contempt. Instead of focusing on the negative behaviors of a partner, for example, he recommends working to cultivate a sense of appreciation and respect for positive behaviors.

While this can take time and effort, it is important to see how any given interaction helps pave the way towards this sense of appreciation. It is helpful to consider other, related, relationship killers such as criticism.

In the case of criticism, he distinguishes critiques of the person’s behavior from their character, urging couples to avoid criticisms of character in favor of expressing positive desires. Rather than accusing a partner of some deficiency, one ought to express an active desire. This can involve pointedly asking for your spouse’s attention, rather than accusing them of never listening.
