“Everywhere You Look, You’ll Find Food”: Emerging Adult Perspectives Toward the Food Media Landscape

In the present study, an attempt was made to study the effect of plant extract on Sexual behaviour of Mutant Strain (Curled) of Drosophila melanogaster. The LC50 has been estimated with 1% of the food media. The virgin females and males were isolated and fed with normal food media for three days. Then sub-lethal concentrations of 0.625 μl / 100 ml food, 1.2 μl /100 ml food, 2.5μl /100 / food of nicotine were mixed in food medium and allowed in flies to feed for two days. Then appropriate combination of untreated / treated males and females were introduced into the mating chamber. Courtship latency, mating latency and copulation duration were studied. After observation of the behaviour, mated flies were allowed to produce progeny. The sexual behaviour of bachelor male and virgin female obtained in the progeny was also studied. The pooled data were analyzed by student t-test and the result indicates p-value significant at 0.05 levels. The courtship latency was affected by in treatment but it is neither dose dependent nor sex dependent.

Over Time

Chapter 2 reviews research and theory on the life story and its development and relations to other aspects of personality. The authors introduce the integrative framework of McAdams and Pals, who described three levels in a broad model of personality: personality traits; personal goals, values, and projects; and the unique life story, which provides a degree of unity and purpose to the individual’s life. This narrative, which develops in late adolescence and emerging adulthood, as individuals become able to author their own stories, includes key scenes of emotional and personal importance to provide a sense of continuity, while remaining flexible and dynamic in incorporating changes in the self over time. The chapter ends with a description of Alison, an emerging adult from our Canadian Futures Study, who illustrates these levels and what they tell about personality development during this period.

Key Concepts

Chapter 6 reviews research on the topic of vocational/occupational development in relation to the McAdams and Pals tripartite personality framework of traits, goals, and life stories. Distinctions between types of motivations for the work role (as a job, career, or calling) are particularly highlighted. The authors then turn to research from the Futures Study on work motivations and their links to personality traits, identity, generativity, and the life story, drawing on analyses and quotes from the data set. To illustrate the key concepts from this vocation chapter, the authors end with a case study on Charles Darwin’s pivotal turning point, his round-the-world voyage as naturalist for the HMS Beagle. Darwin was an emerging adult in his 20s at the time, and we highlight the role of this journey as a turning point in his adult vocational development.
