Resource security impacts men’s female breast size preferences

It has been suggested human female breast size may act as signal of fat reserves, which in turn indicates access to resources. Based on this perspective, two studies were conducted to test the hypothesis that men experiencing relative resource insecurity should perceive larger breast size as more physically attractive than men experiencing resource security. In Study 1, 266 men from three sites in Malaysia varying in relative socioeconomic status (high to low) rated a series of animated figures varying in breast size for physical attractiveness. Results showed that men from the low socioeconomic context rated larger breasts as more attractive than did men from the medium socioeconomic context, who in turn perceived larger breasts as attractive than men from a high socioeconomic context. Study 2 compared the breast size judgements of 66 hungry versus 58 satiated men within the same environmental context in Britain. Results showed that hungry men rated larger breasts as significantly more attractive than satiated men. Taken together, these studies provide evidence that resource security impacts upon men’s attractiveness ratings based on women’s breast size

Behavior and Impact of Zirconium in the Soil–Plant System: Plant Uptake and Phytotoxicity

Because of the large number of sites they pollute, toxic metals that contaminate terrestrial ecosystems are increasingly of environmental and sanitary concern (Uzu et al. 2010, 2011; Shahid et al. 2011a, b, 2012a). Among such metals is zirconium (Zr), which has the atomic number 40 and is a transition metal that resembles titanium in physical and chemical properties (Zaccone et al. 2008). Zr is widely used in many chemical industry processes and in nuclear reactors (Sandoval et al. 2011; Kamal et al. 2011), owing to its useful properties like hardness, corrosion-resistance and permeable to neutrons (Mushtaq 2012). Hence, the recent increased use of Zr by industry, and the occurrence of the Chernobyl and Fukashima catastrophe have enhanced environmental levels in soil and waters (Yirchenko and Agapkina 1993; Mosulishvili et al. 1994 ; Kruglov et al. 1996)

Genetic and neurological foundations of customer orientation: field and experimental evidence

We explore genetic and neurological bases for customer orientation (CO) and contrast them with sales orientation (SO). Study 1 is a field study that establishes that CO, but not SO, leads to greater opportunity recognition. Study 2 examines genetic bases for CO and finds that salespeople with CO are more likely to have the 7R variant of the DRD4 gene. This is consistent with basic research on dopamine receptor activity in the brain that underlies novelty seeking, the reward function, and risk taking. Study 3 examines the neural basis of CO and finds that salespeople with CO, but not SO, experience greater activation of their mirror neuron systems and neural processes associated with empathy. Managerial and research implications are discussed

The centrosome and spindle as a ribonucleoprotein complex

The definitive version was published in Chromosome Research 19 (2011): 367-376, doi:10.1007/s10577-011-9186-7.The presence of nucleic acids in centrosomes and the spindle have been proposed, observed, and reported since the 1950s. Why did the subject remain, perhaps even until today, such a controversial issue? The explanation is manifold, and includes legitimate concern over contamination from other cellular compartments in biochemical preparations. With a typically high background of cytoplasmic ribosomes, even microscopic images of stained intact cells could be difficult to interpret. Also, evidence for RNA and DNA in centrosomes accumulated for approximately 40 years but was interspersed with contradictory studies, primarily regarding the presence of DNA (reviewed in Johnson and Rosenbaum, 1991; Marshall and Rosenbaum, 2000). Perhaps less tangible but still a likely cause for lingering controversy is that the presence of nucleic acids in the spindle or centrosomes will require us to look differently at these structures from a functional, and more to the point, evolutionary standpoint.This work was supported by grants from the NIH (GM088503) and NSF (MCB0843092) to MCA

The relationship between emotional intelligence and customer orientation for pharmaceutical salespeople

Purpose: the purpose of the research was to examine the relationships between salesperson emotional intelligence, dispositional affectivity and customer-orientation levels. Design/methodology/approach: seventy-one pharmaceutical salespeople working in the United Kingdom (UK) provided responses to scales designed to assess emotional intelligence, dispositional affectivity and positive and negative affect. The emotional intelligence and dispositional affectivity scores provided by the salespeople were then analyzed to determine the degree to which they related to customer-orientation levels. Findings: the findings indicated that salesperson emotional intelligence levels were positively correlated with their customer-orientation scores. This finding indicated that UK pharmaceutical salespeople who rated higher in their emotional intelligence levels were also likely to rate higher in customer-orientation. Positive dispositional affectivity levels were also significantly correlated with salesperson customer-orientation levels. This result suggests that UK pharmaceutical salespeople who possessed more positive orientations tended to also be more positively oriented to the customer. However, negative affect levels were not significantly correlated with salesperson customer-orientation levels. Research implications: from a theoretical perspective, these findings provide a venue for future research in professional sales which could focus on the relationships existing between salesperson behaviors/characteristics that relate to salesperson customer-orientation, skills, social desirability and performance. Practical implications: from a practical basis, the findings suggest that pharmaceutical firms in the UK who are focused on increasing the customer-orientation levels of their sales force would be well-advised to assess the emotional intelligence and dispositional affectivity levels of both their applicants and their salespeople and use this information in their selection and training activities. Originality/value: the research reported provides an initial assessment of the relationship between these variables in a pharmaceutical sales situation in the U
