The role of Great Barrier Reef tourism operators in addressing climate change through strategic communication and direct action

The projected decline in reef health worldwide will have huge repercussions on millions of stakeholders depending upon coral reefs. Urgent action is needed to sustain coral reefs into the future. Tourism operators are recognised as stewards of Australia's Great Barrier Reef (GBR), a World Heritage Site, and are taking action on climate change, through their business practices and by engaging guests with interpretation and targeted messages. Yet little is known about how tourism operators along the GBR perceive climate change, or what actions they believe are most effective to address climate change impacts on the GBR. We describe a set of semi-structured interviews with 19 tourism operators in the Whitsundays and Cairns, the most popular tourism destinations along the GBR. Using a thematic analysis to code and report patterns within the data, we show tourism operators recognise the threat of climate change and strongly support increased action to address it. Most respondents are hesitant to engage their guests about climate change despite acknowledging an interest, expertise, and responsibility to do so. Understanding the barriers preventing tourism operators from addressing climate change is an important step towards helping them, and the tourists visiting the region, take action to protect the GBR.     

What a Difference a Year Makes: Time Lag Effect of Information Technology Investment on Firm Performance

How long does it take for a firm to realize the performance benefits of its IT investment? This article explores the time lag effects of IT investment on firm performance. Using longitudinal data of 1421 firm-time observations over a period of six years (1991–1996) as the initial time point of IT investment, we examined time lag effect on firm performance in a five-year time window. The performance data for the sample spans 12 years, from 1989 to 2000. The results demonstrate a strong support for time lag effects on the relationship between IT investment and firm performance. Specifically, our study found that it took an average of approximately three to four years after the year of investment for the firms in our sample to realize the greatest performance benefits. The findings offer useful implications for researchers and managers to better understand the link between IT and firm performance so that they can make wiser decisions to maximize the business value of their investments.     

The Power of One: Dissent and Organizational Life

Over the last 20 years, organizations have attempted numerous innovations to create more openness and to increase ethical practice. However, adult students in business classes report that managers are generally bureaucratically oriented and averse to constructive criticism or principled dissent. When organizations oppose dissent, they suffer the consequences of mistakes that could be prevented and they create an unethical and toxic environment for individual employees. By distinguishing principled dissent from other forms of criticism and opposition, managers and leaders can perceive the dissenter as an important organizational voice and a valued employee. The dissenter, like the whistleblower, is often highly ethically motivated and desires to contribute to the organization’s wellbeing. Recognizing and protecting principled dissent provides the means of transforming organizations. By restoring dignity to the individual, organizations gain more productive and loyal employees, and they create an environment that promotes critical thinking, learning, and a commitment to ethics.

Training as a social purpose: are economic and social benefits delivered?

This paper reports original research which measures the social and economic impact of training and skills development on individuals who participated in training provided by social purpose, nonprofit organizations. An implicit policy assumption is that such organizations contribute to social and economic regeneration. Examining the costs and benefits of training to trainees, an adapted Return on Investment methodology measures any economic benefit, while an Index of Social Benefit measures changes in individual well‐being. The results demonstrate that while changes to both the economic and social well‐being of trainees occur, it does not necessarily relate solely to the training they received. Instead, changes reflect other, often complex, aspects of trainees’ lives, although training may facilitate change. Furthermore, social purpose, nonprofit organizations need to evince the socioeconomic benefits of their training programmes to secure future funding, public or private, but proving their successful delivery may be difficult to determine.     

The Value of Employee Retention: Evidence From a Natural Experiment

We estimate the firm‐level returns to retaining employees using difference‐in‐differences analysis and a natural experiment where the enforcement of employee noncompete agreements was inadvertently reversed in Michigan. We find that noncompete enforcement boosted the short‐term value of publicly traded companies by approximately 9%. The effect is increasing in local competition and growth opportunities, and offset by patenting.     

Right anterior thoracotomy aortic valve replacement is associated with less cost than sternotomy-based approaches: a multi-institution analysis of ‘real world’ data

Background:

Large institutional analyses demonstrating outcomes of right anterior mini-thoracotomy (RAT) for isolated aortic valve replacement (isoAVR) do not exist. In this study, a group of cardiac surgeons who routinely perform minimally invasive isoAVR analyzed a cross-section of US hospital records in order to analyze outcomes of RAT as compared to sternotomy.

Methods:

The Premier database was queried from 2007–2011 for clinical and cost data for patients undergoing isoAVR. This de-identified database contains billing, hospital cost, and coding data from >600 US facilities with information from >25 million inpatient discharges. Expert rules were developed to identify patients with RAT and those with any sternal incision (aStern). Propensity matching created groups adjusted for patient differences. The impact of surgical approach on outcomes and costs was modeled using regression analysis and, where indicated, adjusting for hospital size and geographical differences.

Results:

AVR was performed in 27,051 patients. Analysis identified isoAVR by RAT (n?=?1572) and by aStern (n?=?3962). Propensity matching created two groups of 921 patients. RAT was more likely performed in southern hospitals (63% vs 36%; p?p?p?p?p?Conclusions:

Outcomes analyses can be performed from hospital administrative collective databases. This real world analysis demonstrates comparable outcomes and less cost and ICU time with RAT for AVR.
