The psychology tried to find out at what age does human child develops depth perception. Then, researchers proposed that the human ability to perceive depth is natural instinct. The experiment is to observe and analyze human infants, and see if they can recognize the depth. Of course, the cliff is not real. A big table was set up for the experiment.
The glass cliff is the phenomenon of women in leadership roles, such as executives in the corporate world and female political election candidates , being likelier than men to achieve leadership roles during periods of crisis or downturn, when the chance of failure is highest. The term was coined in by British professors Michelle K. In a study, Ryan and Haslam examined the performance of FTSE companies before and after the appointment of new board members, and found that companies that appointed women to their boards were likelier than others to have experienced consistently bad performance in the preceding five months. Since the term originated, its use has expanded beyond the corporate world to also encompass politics and other domains. Ryan and Haslam's research showed that once women break through the glass ceiling and take on positions of leadership they often have experiences that are different from those of their male counterparts. More specifically, women are more likely to occupy positions that are precarious and thus have a higher risk of failure—either because they are appointed to lead organizations or organizational units that are in crisis or because they are not given the resources and support needed for success.
The glass ceiling is an idea familiar to many. It refers to the invisible barrier that seems to exist in many fields and which prevents women from achieving senior positions. Originally recognised by academics Michelle Ryan and Alex Haslam back in , this is the phenomenon of women making it to the boardroom but finding themselves disproportionately represented in untenable leadership positions. Ryan and Haslam presented evidence that women are indeed starting to secure seats at boardroom tables. But the problem is that their positions are inherently unstable.
However, there are some far more substantial themes and symbols taking place within the novel. One of these themes being the heavy emphasis placed on the glass castle, and also metaphorically what it signifies to Jeanette and her father, Rex. Through extensive deliberation and thought, the meaning of the glass castle becomes clear.
