Listening Environment and the Bottom Line: How a Positive Environment Can Improve Financial Outcomes
Amidst the onslaught of communication at work, employees’ voices can be neglected in favor of the bottom line. This research initiates an exploration of the relationship between employee perceptions of the listening environment at work and organizational financial performance indicators. In this exploratory pilot study, we collected data from N = 65 employees of a single firm with multiple geographically and financially independent units. Using simple regression analysis, researchers compared data between units to determine if employee perceptions of positive qualities of the listening climate are related to improvement in sales and net income. Results suggest a potentially positive relationship between employees’ perceptions of a positive listening environment and these organizational performance indicators, suggesting that listening is an important step in building the communication climate of a productive company. 相似文献

A pilot study of an interactive hazards education program was carried out in Canberra (Australia), with direct input from youth participants. Effects were evaluated in relation to youths’ interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home‐based preparedness activities. Using a single group pretest‐posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre‐ to posttest on both youth (p < 0.01) and parent ratings (p < 0.01). Parent ratings reflected an increase of just under six home‐based preparedness activities. Youth knowledge about disaster mitigation also was seen to increase significantly (p < 0.001), increasing 39% from pretest levels. While personalized risk perceptions significantly increased (p < 0.01), anxiety and worry levels were seen either not to change (generalized anxiety, p > 0.05) or to reduce between pre‐ and posttest (hazards‐specific fears, worry, and distress, ps ranged from p < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi‐experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community. 相似文献

China??s oldest old population is estimated to quadruple by 2050. Yet, poverty rate for the oldest old has been the highest among all age groups in China. This paper investigates the relationship between economic stress, quality of life, and mortality among the oldest-old in China. Both objective economic hardships and perceived economic strain are examined. We base our investigation on data drawn from the Chinese Longitudinal Healthy Longevity Survey conducted between 2000 and 2005. Our sample includes 10,972 men and women between the ages of 80 and 105 in 2000. The data show that about 16% of these oldest-old lived under economic stress in 2000. The risk factors that make one vulnerable to economic stress include age, being male, being widowed or never married, being a minority member, having no education, having no living children, and not having children as main source of income, and having no pension. Economic stress is negatively associated with indicators of quality of life, such as the quality of medical care and mental well-being. The poor quality of life contributes to the higher mortality rate for the oldest old who are under economic stress. Results also show that perceived economic strain increases the risk of mortality by 42% in rural areas, even after controlling for basic demographic characteristics, life style factors, and major health events.?For the rural oldest-old, having children as a main source of income and having access to pension alleviates the negative impact of economic hardship on mortality hazard by 23 and 66% respectively. However, in urban areas, economic stress has no direct impact on the hazard of mortality. 相似文献

Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth. 相似文献

The field of couple and family therapy has benefitted from evidence generated from qualitative approaches. Evidence developed from approaches relying on language and social interaction using naturally occurring recordings of real‐world practice has the benefit of facilitating practice‐based recommendations and informing practice. The aim of this article is to provide an overview of one approach to discourse analysis, Discursive Psychology (DP), demonstrating how a social constructionist framework and focus on discourse can provide an important contribution to the field of therapy. To illustrate the methodological decision‐making process for researchers and/or practitioners who utilize DP, we draw upon a video‐recorded therapeutic session involving Tom Andersen. To conclude, we make recommendations for practitioners using DP to explore and examine therapeutic practice. 相似文献

As medical and surgical advances improve, more young adults with congenital heart disease (CHD) are attending college. This case study illustrates some of the issues that these young adults may face as they attend college and discusses the role that college health practitioners can play in easing that transition. Participants: A case of a male with CHD presenting to the college health clinic with a new onset headache. Methods: The authors discuss some of the unique challenges that college health practitioners may face when caring for students with CHD. In addition, they make recommendations on how best to care for these patients and how best to coordinate care with CHD students other care providers. Results: This student with a history of coarctation of the aorta presented with new onset headaches and was found to have high blood pressure. He was diagnosed with recurrent coarctation, underwent percutaneous treatment with stenting and quickly resumed classes. Conclusions: As more students with CHD enter college, college health providers will need to understand some of the health risks that CHD students face. In addition, understanding some of the optimal ways to coordinate care with CHD providers can ease the transition that CHD students face as they enter college. 相似文献

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs. 相似文献
