Sex In Advertising

Use of Sex in advertising continues despite the public outcry against it. Exposing mature adults to sex based advertising often invites lesser criticism compared to advertising that targets teenagers. Its use in advertising is no more confined to adult programs on television or adult literature; its consequences are far reaching in the context of exposure through mass media. Although some level of sex content might help in selling, the real questions are: how much sex content is appropriate; when is the use of such content appropriate, and for which target audience. The present research aims to explore some of these questions through consumer data in which teenagers are shown a series of print and television advertisements with different degree of sex content for different product categories. This paper attempts to find out the effectiveness of sex based advertising on the overall attitude and behavioural intention of respondents by application of Fishbien Behavioural Intention Model. The paper tries to find out the relationship between the use of sex content in advertisements for commercial and non-commercial product category at different levels of depiction and behavioural intention towards product categories. The results show that the respondents find sex-content based advertisement to be in bad taste in the context of family setting and there is a relatively moderating effect on the behavioural intention of consumers upon exposure to commercial product advertisements.

To date, the genus Amphiduros (Annelida: Hesionidae: Amphidurine) is considered as monotypic. Its single species, Amphiduros fuscescens (Marenzeller, 1875), is well characterised by lacking proboscideal papillae and emerging acicular chaetae, as well as by having three antennae, eight pairs of tentacular cirri and inflated dorsal cirri with characteristic alternating length and colour (transparent, with median orange band and white tips) in live animals. Three specimens, one male and two females, were found below boulders at 5–7 m depth in Punta Santa Anna, Blanes and Cala Maset, Sant Feliu de Guixols (Catalan Sea, NW Mediterranean, Iberian Peninsula). Our finding allowed us to describe different, unreported morphological traits and lead us to support the existence of sexual dimorphism (in terms of colouring, cirri morphology and distribution of sexual products along the body). Despite A. fuscescens having been previously reported from the Atlantic and the Mediterranean (particularly in SE French coasts), the specimens from Blanes represent the first record of the species from the Iberian Peninsula. In addition, our molecular results strongly support that Amphiduros pacificus Hartman, 1961 from California (currently synonymised with A. fuscescens) requires to be re-described and reinstalled as a valid species. In turn, our morphological observations support suggesting all other non-Mediterranean reports of A. fuscescens, including the species still under synonymy (i.e. Amphidrornus izukai Hessle, 1925 and Amphidromus setosus Hessle, 1925) as likely being a cryptic species complex whose the taxonomic status requires further assessment.

Death preparation is an important process as it can help the elderly to achieve ego integrity at the last stage of their lives. This study aims to explore how the ethnic Chinese elderly in Singapore approach issues related to death and dying, and to identify factors that influence death preparation. Descriptive surveys with semi-structured interview questions were used. Eight ethnic Chinese older adults, recruited through purposive sampling, were interviewed. Additionally, 4 adults with a deceased parent were also interviewed to validate and complement the earlier identified themes. Results show that the current generation of Chinese elderly in Singapore do not seem to be averse to talking about issues related to death, and those who find it unnecessary to prepare for death seem to be associated with, among other factors, lesser financial assets and a strong belief in filial piety. With increasing affluence and dissolving traditions, it will be beneficial to draw the attention of the current generation of mature adults on early preparation at the final stage of the lifespan.

The human body has dedicated receptors for sensing temperature and touch, but not wetness. How then is wetness perceived? To test if wetness perception arises from the sensory integration of touch and temperature, and to quantify its measurement in humans, we designed a wetness perception monitor (WPM) which enabled variation of temperature at the fingertips of participants while measuring the pressure exerted on a test surface in the controlled environment of a moisture-free chamber. Thirty randomly selected adults (18+ years) were tested for their perception of dampness/wetness using the WPM. Our data suggest that humans perceive dampness and wetness at average temperatures of 22 ± 0.4°C and 18 ± 0.5°C, respectively, and these sensations are extinguished at temperatures below 16 ± 1°C. Measurements were obtained at an average tactile pressure of 1.5 ± 0.3 kPa. Young adults (18–35 years) sensed wetness at significantly higher temperatures than middle-aged adults (36–55 years) or mature adults (56+ years), who sensed wetness at similar temperatures. We found a surprising sex difference in wetness perception, with females sensing wetness at higher temperatures than males. When the data were screened for outliers, we found that participants whose readings were outside normal ranges, self-reported sensory deficits suggesting that wetness perception could potentially be used as a noninvasive biomarker.

Hormone Balance and the Control of Metamorphosis in Rhodnius Prolixus (Hemiptera)

A technique is described by which the intact larva of Rhodnius can be transfused with blood from another larva without interfering with ecdysis. If the 4th-stage larva receives blood from a 3rd-stage larva it develops characters little different from those of the 4th instar. This is attributed to the 3rd-stage larva producing juvenile hormone at a higher concentration. If the 4th-stage larva at 24 hr. after feeding receives blood from another 4th-stage larva at 8 days after feeding it develops characters intermediate between those of the 4th and 5th instars. This is attributed to the juvenile hormone being introduced too early in the moulting cycle. The hormone balance is upset by abnormal temperatures. The 4th-stage larva will not moult at a temperature of 36° C. although the larvae can survive up to about 40° C. At temperatures a little below 36° C. moulting is somewhat delayed and the characters developed are slightly ‘adultoid’ (prothetely). This is attributed to slightly reduced activity of the corpus allatum. At temperatures below 20° C. moulting is greatly delayed and the characters developed are slightly ‘juvenile’ (metathetely). This is attributed to relatively increased activity of the corpus allatum. Low concentrations of oxygen (less than 5 %) have an effect similar to that of high temperature. If 5th-stage larvae of Rhodnius receive implants of corpora allata from mature adults of Periplaneta they develop into 6th-stage larvae and many of these subsequently into 7th-stage larvae. The ‘juvenile hormone’ appears to be the same in the two insects. No evidence could be obtained for the persistence of juvenile hormone in the blood from one instar of Rhodnius to the next. The hypothesis of an active elimination of juvenile hormone by the corpus allatum at the time of metamorphosis remains therefore unproven.

Chapter 6 examines Plato’s account of moral education in the Republic. It argues that musical and gymnastic training in the Kallipolis primarily aim at shaping the spirited part of the soul through social, political, and cultural influences and practices. In particular, music aims to make spirit gentle and instill in it the right emotional habits toward moral and immoral people, actions, and objects in the world. Gymnastics, meanwhile, aims to invigorate it and make it “strong” enough to act as reason’s “ally” effectively. Music and gymnastics also have important effects on reason and appetite as well, however. Music exercises reason and prepares it for its proper function in the souls of mature adults, and gymnastic training promotes necessary appetites while eliminating or preventing unnecessary ones.
