Perceived Environmental Uncertainty

Perceived environmental uncertainty is an individual response to stimuli in the internal and/or external environment. The measurement of uncertainty in the health care environment is important in order to characterize the impact of this phenomenon on nursing practice. This study describes the development, pilot testing, and initial psychometric evaluation of the Perceived Environmental Uncertainty in Hospitals Scale (PEU-H) in a sample of 95 hospital staff registered nurses. Principal components analysis of the PEU-H was conducted and indicated that the factor structure represented one factor that explained 37.3% of the variance. Internal consistency reliability using Cronbach’s alpha was .83, which is acceptable for a scale in the early stages of development.

Perceived Environmental Uncertainty

The focus of this study was the perceived environmental uncertainty (PEU) of teachers in two selected elementary schools in a minority/majority context. It attempted to determine the sources of uncertainty that are perceived by teachers in a site-based management (SBM) elementary school and a non-site-based management elementary school. Specific items were examined to determine which indistrict and out-district matters were related to uncertainty and to explore whether or not the two groups of teachers in the selected schools were different regarding their perceived environmental uncertainty. A basic causal-comparative design was employed and the Perceived Environmental Uncertainty Index (PEUI) developed by Singh (1991) was used to collect data. Means, standard deviations and t-tests were calculated to quantify and summarize the data. Findings indicate that the PEU levels for the SBM school were lower than that of the non-SBM school; specific in-district and out-district items rated as most unclear and significant are different for both schools. However, both schools were concerned with the impact of state legislature on job. There is a significant difference in in-district PEU, out-of-district PEU and total PEU between the two schools. These results seem to suggest that site-based management is a viable alternative for reducing and coping with environmental uncertainty. However, further research needs to focus on other levels of school following a SBM approach. Additional studies should address correlations between perceived environmental uncertainty and student success.

Perceived Environmental Uncertainty

<p>The aim of this paper is to explore the impact of environmental and organizational factors on activity-based costing (ABC) use. These variables are studied respectively through the perceived environmental uncertainty, and the organizational structure represented by both horizontal and vertical decentralization.</p><p>Data were collected from 62 Moroccan firms, operating in different sectors, via a questionnaire survey. The findings indicated that ABC use is not associated with perceived environmental uncertainty and horizontal decentralization. However, firms with a high degree of vertical decentralization use more ABC than those with a centralized vertical structure (p&lt;10%).</p><p>This research adds to general knowledge and offers insights into management accounting since the study is conducted in a developing country that has specific environmental and organizational characteristics. Previous research has studied perceived environmental uncertainty in other contexts of innovations. In our paper, we investigate the case of ABC and we.analyse decentralization with both horizontal and vertical dimensions.</p>

Perceived Environmental Uncertainty

Purpose This paper aims to examine the impact of employee-based brand equity (EBBE) and perceived environmental uncertainty (PEU) on firm performance. Design/methodology/approach Data were collected through an e-mail survey from fast-moving consumer goods (FMCG) firms in the UK and UAE. Sample sectors included cosmetics and toiletries, household care products, packaged food, soft drinks and tobacco firms. Quantitative data were analyzed using structural equation modeling. Findings The results suggest strong support for the hypothesized relationships, thereby providing strong validation for the proposed model. One interesting finding was that the PEU affected employee brand equity significantly stronger in the UK than in the UAE. This phenomenon is explained in the discussion section. Research limitations/implications Although several studies have indicated several other elements for EBBE, such as brand commitment and brand citizen behavior, the authors borrowed King et al.’s (2012) EBBE concept and limited their variables on EBBE for brand endorsement, brand allegiance and brand consistent behavior. Practical implications Knowledge is expanded through an empirical study validating the proposed model, which provides meaningful insights for developing training tools for internal brand management. Firms have to increase the brand manager’s commitment to increase the employee brand equity, which in turn increases the firm’s performance. Originality/value This paper makes three imperative contributions to the branding literature: expanding the existing brand equity literature to incorporate employee brand equity; being the first known empirically tested PEU on employee brand equity; and empirically testing employee brand equity, which has been ignored in branding literature on firm performance.

The indoor air of a hospital is always full of bacteria and viruses due to patients with different diseases. These bacteria and viruses could be highly infectious to the people in the hospital irrespective of their health conditions, and could be hazardous to the patients, their care takers, and hospital staff. Thus, keeping a good hospital air quality is very essential to the operation of the hospital. This study aims at enhancing ventilation of the interior lighting of hospitals with germicidal capabilities. Air disinfection is accomplished by adding the specially designed disinfecting filters and fans to existing embedded lamps in the hospitals. The embedded lamp has a square shape of 601 mm in width and 112 mm in thickness. In the design stage, the air flow inside the embedded lamp with the added filters and fans was investigated by numerical simulation using a computational fluid dynamics (CFD) tool. Three designs, referred to as Types 1, 2, and 3, were evaluated using steady-state CFD flow simulations. The ventilation rate of the Type 1 design was about 251.9 CMH, and 348.3 CMH for the Type 2 design by increasing the fan outlet area. However, even though the ventilation was increased by 34%, the flow field of the Type 2 design was not uniform, resulting in flows being circulated around the side locations. Thus, the Type 3 design further treats this aspect by streamlining the outlet geometry and adding flow guiding vanes to reduce flow resistance and flow unsteadiness; the corresponding air ventilation rate reached 376.3 CMH. Hence, the Type 3 design was fabricated and tested. The test results confirm that the design not only has a higher ventilation rate but also operates under a smaller pressure drop, thus accomplishing the goal of providing good air quality in the hospital environment efficiently. Moreover, the associated flow noise is reduced by about 8 dBA. Hence, both an increase in the air ventilation rate and a reduction of noise are achieved simultaneously by the present method.
