Gibson and Tesone (2001) discuss management fads particularly in terms of how they develop and their life cycle. They offer five management fads as examples and illustrate how these management fads have evolved through the stages of their life cycle.
Describe a current management practice that you are familiar (not one of the five already discussed in this article) with from your courses or your own first-hand experience that you suspect may be a fad and illustrate in detail how you believe this practice has moved or is moving through the stages of its life cycle.
In what stage do you think the practice currently lies? Thoroughly explain.
Do you expect this practice will “go away, or slip from individual notoriety into the general content of management practices”? Thoroughly explain.
Think about the many changes that have occurred in the workplace due to the COVID-19 pandemic. What, if any, fads do you think have resulted? Do you think they will “stick?” Discuss.
h (Danio Rerio) are model fish due to their homology of their genome being 70% similar to humans and the fact that they are being equally exposed, if not more to BPA due to our waste that is contaminating the aquatic environment.1 Therefore, In order to understand biological, chemical and genetic structures that are effected there is a need for toxin observation and it’s costs due to exposure. Fish, wildlife and ourselves have been greatly affected by toxins found the environment. Water pollution has been suspected to be the cause of damage to the reproductive health, lifespan, embryonic and larval development of fish populations.2 In one experiment the dose amount vs. effects was tested, the low dose of BPA exposure being 5 μg/L, the intermediate dose being 10 μg/L, and the high BPA dose being 20 μg/L. The goal was to determine which of these concentrations (which are common in the environment today) would have an effect on the reproductive system. The results of the experiment showed a blocked ovulation period on the eighth day of the BPA treatment in fish on the low BPA concentration. The fish that received the intermediate(10 μg/L) BPA concentration and high concentration(20 μg/L) did not show significant changes compared to the control fish with no BPA concentration. The low concentration of BPA (5 μg/L) significantly affected estrogen receptor 1 and estrogen receptor 2a yet not the other genes involved in oocyte growth such as; estrogen receptor 2b, steroidogenic acute regulatory protein, cytochrome, and follicle stimulating hormone receptor (Fig.4). This experiments conclusion was in line with the rainbow trout’s conclusion, the lowest concentration of BPA proved to be the most harmful. This affected the D.rerio maturation and oocyte growth. In another experiment zebrafish were used to detect toxicants (including BPA) and to discover the health related effects exposure has to humans. Zebrafish are not only great to experiment on because of their genome is similar to humans but their embryo and larvae are transparent which allows observation to see if there are any malformations in early stages. Zebrafish were treated by putting BPA (powder form) mixed in with their fish food. Fish that were sexually mature (usually 3 months) were used and marked by fluorescent dye. Fish were divided into 3 groups of 8 fish resulting in a total of 24 fish treated. Each group was separated into its own aquarium and fed with food that could or could not be BPA treated, twice a day for 6 months. To test the fertility of the fish they were mated with untreated fish(Fig 9). Offspring was then cultivated and observed for mutations. Some effects of the BPA food were a decrease in size of ovaries to the point they almost disappeared. Males that were tested also showed a decrease in testes size and fertility(Fig. 10). In the initial generation which automatically resulted in survival rate being lowered, an increased rate of abnormality in offspring due to the ovaries and testes retracting. The first generation appeared normal but whe>GET ANSWER
