Evolutionary theory of human sexuality and human sexual strategy:

In addition, the systemic administration of both the polar and neutral reno-medullary lipids reduces arterial blood pressure (Muirhead & Pitcock, 1980).

The drive towards thinness: a manifestation of female intrasexual competition?

This legislation has had the effect of a change in analgesic formulation, usually towards that of a single drug such as aspirin or paracetamol (acetaminophen).

There is no reason to doubt that reproductive suppression occurs in the human female as it does in most mammalian species. Furthermore it is entirely plausible that mechanisms such as kin selection and parental manipulation would be implicated in the adaptation of reproductive suppression (Voland & Voland, 1989). The involvement of the mechanism of kin selection implies that reproductive suppression can occur as a form of altruism towards kin. This is similar to the view proposed by Demaret (1991b) who suggested that anorexia may be an analogue to ‘the helper at the nest’ found in a number of species. However, while studies conducted in some pre-industrial societies, have found that daughters born early tend to increase their parents reproductive success (see Turke, 1988), no study to my knowledge has demonstrated increased fertility in parents of anorectic patients.

Voland & Voland (1989) suggest that anorexia nervosa is an emergency strategy that has evolved through selection that comes into play to suppress reproduction when other controls fail. This is achieved through the reduction of the critical fat mass to below the threshold for ovulation. is suggested that certain features within present day environment have led to the increase in the use of this emergency strategy.

Organic ion accumulation and gluconeogenesis in renal cortical slices may be poor indicators of early toxic effects to the kidney resulting from cisplatin administration because these parameters are not affected except at high doses.

The co-administration of putrescine (Ohmori & Tabei, 1983) or N-3,5-dichlorophenyl-succinimide (Ito et al., 1974) with dimethylnitrosamine caused a dose-related incidence of up to 100% renal tumours after 100 weeks.

Toward a Lexico-Semantic Theory ofLanguage and Language Learning.

Anorexia nervosa has been considered by some to be a developmental disorder (Gordon, 1990). Such a view would be consistent with the present hypothesis which would contend that the early onset form of eating disorder is a specific disorder of female sexual development which results in the disruption of mate attraction strategy.

April 1991 - Scientific American

The factors discussed so far in connection to the drive towards thinness such as delayed reproduction and the instability of long-term mateships are likely to be significant factors in late onset eating disorders (mostly bulimia) but not in the early onset type (mostly anorexia).

(1991) "Towards a Dynamic ..

On the other hand, the demonstration that the occurrence of light hydrocarbon-related adenocarcinomas is specific to male rats shows that there are examples where the molecular understanding of a renal lesion in animals is irrelevant to humans.

The Porter Hypothesis After 20 Years: ..

To summarise, therefore, it is contended that declining fertility in Western societies has led to the preservation of the nubile shape among increasing numbers of post-nubile women leading to the rise of the novel phenomenon of the pseudo-nubile female. This process has been associated with a process of increasing status and power of females in these societies, an increase in short term mating strategies as well as a loosening of marital ties and disruption of extended kinship bonds. The above factors have led to increased female intrasexual competition for desirable long-term mates which has resulted in the drive towards thinness. The extreme variant of this is what we call eating disorders.

The main objective of this paper is to test the Porter hypothesis ..

It may be worth adding here that the media are likely to have had a significant effect in the escalation of this phenomenon. In the modern environment, the existing visual stimuli include not only females who are seen in real life but also ones that appear on the television screens, movies and magazines who although are never known or seen in the flesh may well be mistaken for ‘competitors’. The finding that the drive towards thinness correlated positively with the amount of time young women spent watching soaps and music videos on television (Tiggemann & Pickering, 1996) would be consistent with the present formulation.

the effects of environmental investments on efficiency in ..

Female intrasexual competition may also explain the finding in an American sample, of a relationship between thinness of females of similar educational status (measured through the thickness of subcutaneous fat) and being married to men of high socio-economic status (Garn, Sullivan & Hawthorne, 1989). This suggests that the females who pursued this strategy have had greater success in mate attraction/retention.
