Wisdom from Executive Female Leaders: What Can Organizations, Executive Education Programs, and Graduate Students Learn?

This qualitative study focused on the perceptions and experiences of senior executive female leaders and sought answers to the following questions: “What can others learn from executive female leaders, What can organizations do to retain and advance female leaders, and How can executive education programs and institutions of higher learning better develop female graduate students for leadership positions?” Twelve senior leaders were interviewed who shared the opportunities and challenges they faced as they made their climbs to executive leadership positions

Optimisation of material properties for the modelling of large deformation manufacturing processes using a finite element model of the Gleeble compression test

The finite element modelling of manufacturing processes often requires a large amount of large plastic strain flow stress data in order to represent the material of interest over a wide range of temperatures and strain rates. Compression data generated using a Gleeble thermo-mechanical simulator is difficult to interpret due to the complex temperature and strain fields, which exist within the specimen during the test. In this study, a non-linear optimisation process is presented, which includes a finite element model of the compression process to accurately determine the constants of a five-parameter Norton–Hoff material model. The optimisation process is first verified using a reduced three-parameter model and then the full five-parameter model using a known set of constants to produce the target data, from which the errors are assessed. Following this, the optimisation is performed using experimental target data starting from a set of constants derived from the test data using an initial least-squares fit and also an arbitrary starting point within the parameter space. The results of these tests yield coefficients differing by a maximum of less than 10% and significantly improve the representation of the flow stress of the material

Effects of Corn Oil and Benzyl Acetate on Number and Size of Azaserine-Induced Foci in the Pancreas of LEW and F344 Rats

The response of LEW and F344 strain rats to the pancreatic carcinogen azaserine was compared using the size and number of azaserine-induced acidophilic acinar cell foci and nodules as parameters in a 4-month experiment. A second experiment compared the effect of corn oil intake by gavage and dietary routes on the growth of azaserine-induced pancreatic lesions in LEW rats. A third experiment tested the activity of benzyl acetate in regard to its ability to induce acinar cell foci or to promote the growth of such foci in azaserine-treated rats. The results showed that equivalent doses of azaserine induce two to seven times more foci in LEW than in F344 rats, and that LEW rats have a higher incidence of spontaneous foci than F344 rats. Azaserine-treated LEW rats that were given 5 mL corn oil/kg body weight 5 days per week by gavage developed more acinar cell foci than rats fed a basal diet (chow). Addition of an equivalent amount of corn oil to chow had a similar effect of enhancing the development of foci. Rats of neither strain developed acinar cell foci when benzyl acetate was given by gavage or in the diet nor was there evidence that benzyl acetate has a significant effect on the development of foci in azaserine-treated rats. These studies also demonstrate that the azaserine/rat model of pancreatic carcinogenesis which was developed in LEW rats can be adapted for use with F344 rats

Effects of corn oil and benzyl acetate on number and size of azaserine-induced foci in the pancreas of LEW and F344 rats.

The results showed that equivalent doses of azaserine induce two to seven times more foci in LEW than in F344 rats, and that LEW rats have a higher incidence of "spontaneous" foci than F344 rats. Azaserine-treated LEW rats that were given 5 mL corn oil/kg body weight 5 days per week by gavage developed more acinar cell foci than rats fed a basal diet (chow). Addition of an equivalent amount of corn oil to chow had a similar effect of enhancing the development of foci.

An exploratory study of listening skills of professionals across different cultures

The significance of listening skills for the efficiency and effectiveness of individual and organizational success is starting to be recognized around the world. This study sought to explore the listening skills of working professionals from three countries – India, Malaysia and the United States of America (USA). A total of 633 completed surveys were received from working individuals within the three countries. The results show the respondents from Malaysia have lower self-perceived listening competencies compared to India and USA. The study found no significant difference on listening skill due to age differences. However, respondents within the age group of 61 to 65 years old were found to be better listeners
