Development and Validation of the Workplace Intergenerational Atmosphere Scale

This dissertation details the development and validation of the Workplace Intergenerational Atmosphere (WIA) scale over two studies. Given the growing number of older adults in the American workforce and the possibility of four generations working side by side, the WIA scale was designed to measure attitudes and perceptions about workers of different ages in the workplace. In Study 1, using a sample of workers from a non-profit organization, 23 initial items were reduced to 18, including five subscales: Intergenerational Contact, Workplace Intergenerational Retention, Positive Affect, Workplace Generational Inclusiveness, and Lack of Stereotypes. The relationships between WIA scores and mentoring, perceptions of older workers, and job satisfaction were explored through traditional statistical techniques. In Study 2, using a larger sample of workers from a long-term healthcare organization, the WIA scale and its subscales were further refined, and its structural, criterion, convergent, and discriminant validities were supported via structural equation modeling. Validation should be expanded to include more diverse samples, but results suggest that the WIA scale measures a unique concept and should be of use to organizations interested in improving workforce intergenerational dynamics

What’s your Snapscore? Correlations to Personality, Narcissism, and Anxiety

Snapchat is a popular social media network, but considerably less researched than other more established platforms. The purpose of this study was to examine how the amount of Snapchat use is correlated to personality, narcissism, and anxiety. We hypothesized there would be positive correlations between Snapchat usage and narcissism, extroversion, and anxiety. Using data from a convenience sample of participants recruited from Amazon Mechanical Turk, Pearson’s correlations and t-test analysis provided insight on these connections. There were significant positive correlations between Snapchat usage and narcissism, anxiety, and extraversion, but t-test analyses revealed that the users with low Snapscores had higher narcissism, anxiety, and extraversion

Recovery of viral RNA and infectious foot-and-mouth disease virus from positive lateral-flow devices

Foot-and-mouth disease Virus (FMDV) is an economically important, highly contagious picornavirus that affects both wild and domesticated cloven hooved animals. In developing countries, the effective laboratory diagnosis of foot-and-mouth disease (FMD) is often hindered by inadequate sample preservation due to difficulties in the transportation and storage of clinical material. These factors can compromise the ability to detect and characterise FMD virus in countries where the disease is endemic. Furthermore, the high cost of sending infectious virus material and the biosecurity risk it presents emphasises the need for a thermo-stable, non-infectious mode of transporting diagnostic samples. This paper investigates the potential of using FMDV lateral-flow devices (LFDs) for dry transportation of clinical samples for subsequent nucleic acid amplification, sequencing and recovery of infectious virus by electroporation. FMDV positive samples (epithelial suspensions and cell culture isolates) representing four FMDV serotypes were applied to antigen LFDs: after which it was possible to recover viral RNA that could be detected using real-time RT-PCR. Using this nucleic acid, it was also possible to recover VP1 sequences and also successfully utilise protocols for amplification of complete FMD virus genomes. It was not possible to recover infectious FMDV directly from the LFDs, however following electroporation into BHK-21 cells and subsequent cell passage, infectious virus could be recovered. Therefore, these results support the use of the antigen LFD for the dry, non-hazardous transportation of samples from FMD endemic countries to international reference laboratories

INTERJECTIONS IN LITERARY READINGS AND ARTISTIC PERFORMANCE

Abstract Numerosity and privileges of occurrence of various types of interjections (primary conventional, primary non-conventional, secondary, and onomatopoeic) were investigated in three different literary readings of Winnie-the-Poo
