Because of perceived deficiencies in the state of the practice of designing escalators and moving walkways, a microsimulation-based model of pedestrian behavior in these moving belt systems was created. In addition to implementing walking and stair climbing capabilities from existing pedestrian flow literature, the model utilized following behavior and lane change decision logic taken form studies performed in the field of automotive traffic flow theory. By combining research from these two normally independent fields with moving belt operational characteristics, a solid framework for the simulation was created. The model was then validated by comparing its operation to real world behaviors and performance metrics found in the literature in order to verify that the simulation matched the choices made by actual pedestrians. Once this crucial function had been completed, the model could finally be used in its original purpose of determining the capacity of a belt under region-specific input parameters. This paper also discusses other applications for which the model is suitable, including performing sensitivity analysis of both existing and proposed belt systems, analyzing the impacts of operational rule sets on the performance of escalators and moving walkways, and analyzing the effect of queue growth on the storage area needed for pedestrians in an ambulatory facility. Through the use of this model and the logic contained within it, engineers and planners will be able to gain a more accurate understanding of pedestrian flow on moving belts. The result of this increased understanding will be more effective and more efficient transportation systems. / Master of Science

Women face barriers to advancement in male-dominated fields (Glass Ceiling) and in female-dominated fields (Glass Escalator). More research is needed to elucidate the causes of these barriers in order to reduce the negative effects on women’s advancement. This study attempted to broaden the literature through the experimental examination of the glass escalator to further understand the gender inequalities that are seen in female-dominated fields. It employed a factorial design to examine the impact of gender, gender make up of an occupation, and level of authority within that occupation on a supervisor’s evaluation of an employee and decision to offer promotion, mentoring, and increase income and vacation time. Participants were recruited from Amazon Mechanical Turk and were just over half women, predominantly White and heterosexual, had a bachelor’s degree or higher, currently engaged in full-time employment, and half indicated their household income to be between $25,000 and $74,999. Each participant was presented with a single vignette of an employee file who was eligible for a promotion from a female-dominated (nurse), male-dominated (engineer), or gender neutral (accountant) occupation. They evaluated the employee’s performance and made recommendations for promotion, increasing raise and vacation days, and offered mentoring. Participants also completed the Gender Attitude Inventory (GAI; Ashmore, Del Boca, & Bilder, 1995) to better understand the role that gender attitudes play in gender bias in promotion decision-making. Multiple analysis of covariance was utilized to examine main effects and interaction effects of target employee gender, gender-type of occupation, and level of authority of the occupation. Hypotheses that men will be more likely to be promoted into positions with more authority, and women will be viewed as most competent in positions that are female-typed with the least amount of authority were not supported. Results showed that gender attitudes were weakly related to an employee’s performance evaluation, raise, and mentoring. Significant differences were found on the GAI where participants identifying as women, gay, and with a graduate degree had more liberal gender attitudes. Possible explanations for the predominantly insignificant results and future directions are discussed. Suggestions are provided for increasing the strength of the manipulation and factors that possibly decreased the salience of gender. Future experimental and continued qualitative studies in applied settings are recommended to identify causal influences of the glass escalator that examine factors of race, SES, and sexual orientation.

Indiana University-Purdue University Indianapolis (IUPUI) / This project examined several research questions using survey research of men working in nursing at a Midwestern hospital corporation. The first is why do men enter a nontraditional occupation, such as nursing? Second, what are their experiences working in nursing, as a nontraditional occupation for men? What problems do they encounter, such as discrimination or stereotyping? What advantages do they enjoy, such as promotions or preferential treatment? Third, what factors cause men to stay in nursing for long periods of time? Answers to these questions can help us understand how more men might be recruited to enter nursing, including breaking down the challenges men in nursing might face.

Abstract In every prosperous city of the world , we could see the elevators in the huge buildings and great mansions , the escalators in the department stores and the passenger conveyers in the shopping mall or in the airport. People were dependent on the products of the elevator properties in deep. In this research , we used the analysis of the Delphi to inquire into the elevator property to find out the factors that made this property to be successful. The most important characterists are¡Gthe Global Logistics Management, the Creative Technlogical Management and Selling to the Top. The distinguishing features of the products of the elevator¡¦s property were such as¡G 1. In TAIWAN, the top 8 of the elevator¡¦s factory owners manufactured the elevators and also the related products together with the Global Logistics Management. 2.

The expenses of every project were enormous and the competed tactics were nimble. 4. Except for the top director , no one could make the decision. 5. It was not easy to handle the extensively selling market. 6. The educational background and the professional career of every regional director of the competed factory were all superior. In this study, I sincerely hope that I could do whatever is best for the elevator¡¦s property.

Bakgrund: Infrastruktur och hur vi väljer att bygga våra städer styr befolkningens aktivitetsmönster. Infrastrukturen och tekniken har utvecklats i samhället och gett alternativa tillvägagångssätt att ta sig upp och ner mellan olika våningsplan. Fler människor väljer rulltrapporna och hissen före trapporna och går miste om de positiva effekterna som är kopplade till vardaglig trappgång. Syfte: Syftet med studien var att undersöka om det gick att påverka människors beteende att ta trappan istället för rulltrappan, genom att förändra miljön med en trappmålning. Metod: Studien var en prospektiv, kvasiexperimentell, deskriptiv interventionsstudie med ett konsekutivt urval. De personer som passerade trapporna/rulltrapporna under en förutbestämd tidsperiod studerades. Mätningarna gjordes med hjälp av ett system för trafikmätningar(OTUS3D) och pågick under tre veckor. Först mättes en baseline under vecka ett, målning av trappan under vecka två samt mätning för interventionen vecka tre. Resultatsammanfattning: Denna studie visade ingen förbättring gällande beteendeförändring hos fotgängare. Den statistiska signifikanta minskningen av fotgängare i trappan kan ha sin förklaring i de stora antalet deltagare i studien. Slutsats: Det finns många olösta frågor om vad som påverkar människors beteende i deras dagliga liv. Antalet faktorer är större än den här studien har testat. Andra interventioner i form av annat motiv eller arkitekturell utformning kan ge andra resultat. / Background: Infrastructure and how we choose to build our cities control the population's patterns of activity. Infrastructure and technology have evolved into society and provided alternative approaches to get up and down between different floors. More people choose the escalators and the elevator before the stairs and miss out on the positive effects that are connected to everyday stairwells. Purpose: The purpose of the study was to investigate whether it could affect people's behavior to take the stairs instead of the escalator, by changing the environment with a stairway painting. Method: The study was a prospective, quasi-experimental, descriptive intervention study with a consecutive selection. The people who passed the stairs / escalators for a predetermined period of time were studied. The measurements were made using a traffic measurement system (OTUS3D) and lasted for three weeks. First, a baseline was measured during week one, painting the staircase during week two, and measurement for the intervention week three. Summary of results: This study showed no improvement in behavioral change in pedestrians. The statistically significant decrease of pedestrians in the stairs can be explained by the large number of participants in the study. Conclusion: There are many unresolved questions about what affects people's behavior in their daily lives. The number of factors is greater than this study has tested. Other interventions in the form of another motive or architectural design may produce other results.

This master's thesis covers the construction analysis of an escalator by the Otis a.s. company and the conception of its modernization called "In-truss".This type of modernization consists in preserving the supporting construction of the 506-type escalator into which the components of newer 506-NCE series are to be built in. Such operation requires modifying the construction and creating adaptors used to anchor the new components to it. These modifications lead to the stress testing of the construction, that is done by using the finite elements method in NX-Ideas software. The thesis contains the design of selected subsystems of the escalator, the stress testing of the new supporting construction and the creation of volume model in CREO-Parametric application for further use.
