Using visuo-kinetic virtual reality to induce illusory spinal movement: the MoOVi Illusion
Illusions that alter perception of the body provide novel opportunities to target brain-based contributions to problems such as persistent pain. One example of this, mirror therapy, uses vision to augment perceived movement of a painful limb to treat pain. Since mirrors can't be used to induce augmented neck or other spinal movement, we aimed to test whether such an illusion could be achieved using virtual reality, in advance of testing its potential therapeutic benefit. We hypothesised that perceived head rotation would depend on visually suggested movement.
In a within-subjects repeated measures experiment, 24 healthy volunteers performed neck movements to 50
of rotation, while a virtual reality system delivered corresponding visual feedback that was offset by a factor of 50%-200%-the Motor Offset Visual Illusion (MoOVi)-thus simulating more or less movement than that actually occurring. At 50
of real-world head rotation, participants pointed in the direction that they perceived they were facing. The discrepancy between actual and perceived direction was measured and compared between conditions. The impact of including multisensory (auditory and visual) feedback, the presence of a virtual body reference, and the use of 360
immersive virtual reality with and without three-dimensional properties, was also investigated.
Perception of head movement was dependent on visual-kinaesthetic feedback (
= 0.001, partial eta squared = 0.17). That is, altered visual feedback caused a kinaesthetic drift in the direction of the visually suggested movement. The magnitude of the drift was not moderated by secondary variables such as the addition of illusory auditory feedback, the presence of a virtual body reference, or three-dimensionality of the scene.
Virtual reality can be used to augment perceived movement and body position, such that one can perform a small movement, yet perceive a large one. The MoOVi technique tested here has clear potential for assessment and therapy of people with spinal pain.

How a Plane Crash Changed My Life
In 1983 Ted Leonsis survived a crash landing of a plane he was on.This fateful event proved to be a pivotal point in his life. One of the byproducts of that near-death experiences is Leonsisʼ list of 101 things to do before he died‐a “bucket list” before the movie of that title came out. Leonsis has managed to accomplish more than two-thirds of the things on his list including owning a sports franchise (the Washington Capitals), changing someoneʼs life via a charity, sailing the Caribbean, and being on the cover of a magazine. As impressive as these accomplishments are, they do not reveal the person underneath these accomplishments or what has driven this serial entrepreneur. In previous interviews appearing in NEJE, we have explored how a personʼs faith tradition impacts how they run and manage their businesses. In this interview Leonsis reveals how his life was shaped by both his early childhood and the transformational experience of a crash landing. This interview examines not only what drove Leonsis to success, but also why he feels failure is important. Along, the way he offers his perspective on corporate social responsibility and why it is so critical for individuals and companies to give back to society. And finally, Leonsis shares what he has learned about the secret to happiness.

Exiting and Entering: An In-Depth Examination of Former Journalists’ Decisions to Leave the Field and Undergraduate Students’ Expressed Motivations to Enter the Field
This paper endeavors to examine and explore the different motivations to enter, and exit, the field of journalism. These questions are important because the field of journalism is rife with precarity, stress, and practices of being overworked and underpaid. Journalism has traditionally been thought of as a prestigious occupation that serves democracy through fulfilling a “watchdog” role that keeps the public informed on matters of societal importance. As such, this project examines whether the idea of serving democracy is still a primary motivating factor for students who wish to enter the field. Conversely, this project also aims to explore the reasons given by journalists as to why they attrit from the field and whether the reasons given relate to journalism as an institution not being perceived as fulfilling its role in society.

Harry F. Byrd, Jr. school of business, institute for entrepreneurship: A concept paper that became a reality
The Harry F. Byrd, Jr. School of Business at Shenandoah University engaged in an intense planning process in the fall of 2004. In addition to clarifying its mission and strategic directions, the Byrd School clearly articulated its vision: to become recognized as a provider of individualized business education driven by entrepreneurial thinking, global understanding, and ethical practice. The development of the Institute for Entrepreneurship described in this article is a critical step in actualizing this vision.

Textual Analysis of the Soma Mining Disaster
This paper is a case study of the Soma mining disaster that took place on May 13, 2014. The disaster ultimately resulted in the deaths of 301 miners. To better understand how this incident was portrayed in newspaper coverage, a textual analysis of frames was conducted. In order to garner the broadest possible scope regarding the depiction of this disaster, newspapers with varying political and religious affiliations were examined. These frames were analyzed to identify elements of classical propaganda in news organizations regardless of political or religious affiliation. Coverage from four daily newspapers (Yeni Şafak, Sabah, Cumhuriyet, and Everensel) was analyzed for frames that emphasize nationalism, Islamism, or worker-employer relations. The study found that the most commonly used elements of classical propaganda were: emotional appeals and flag waiving—or the invocation of nationally held symbols to motivate action or thought the audience would not have done on their own volition.

Principles before profits: An interview with S. Truett Cathy
Recent attention has been given to organizations that claim to run on faith-based principles. Activities such as at work bible study groups, charitable giving, and the individual practices of the owners are often the focus of such discussions. In such discussions little attention has been paid to those who not only hold strong religious views, but have chosen to put those views into practice‐even when it may not appear to make good business sense.
Since 1946, S. Truett Cathy, founder and chairman of Chick-fil-A Inc., has run his enterprises based on his understanding of Christian principles. Starting with his first restaurant, the “Dwarf Grill,” which he opened with his brother Ben in 1946, continuing when he opened the first “Chick-fil-A” in 1967, and even as he finished the remodeling of the companies headquarters in 1997, S. Truett says he tries “to glorify God by being a faithful steward of all that is entrusted to us and to have a positive influence on other people. . . .” In fact, this purpose is engraved in a bronze plaque that rests at the entrance to Chick-fil-A’s corporate headquarters in Atlanta, Georgia.
In practice, this purpose has lead S.Truett to never have his businesses open on Sunday, a time in the quick service industry that normally generates 20 percent of revenue. It has caused him to shut down another restaurant venture, Markos in Florida, rather than serve alcohol, which most patrons wanted. Despite his staunch adherent to principles that seem to run counter to “good business sense,” S.Truett Cathy has built a successful, privately held organization that operates in 38 states, has more than 1,300 franchisees, and generates over $2 billion a year in revenue.
In the following interview, S.Truett offers his perspective on why focusing on principles is more important than focusing on profits and what he thinks it takes to succeed in business and in life.

The Performance of Faith-based Mutual Funds: A Matched-Pair Approach
Using a matched-pair approach, this study investigates the performance of faith-based mutual funds in the United States from 2007 to 2015. It finds that faith-based funds do not systematically underperform similar secular SRI or conventional funds. Faith-based funds tend to be small and share with similarlysized conventional funds the challenge of attaining sufficient size to fully exploit economies of scale in investing. Given the high growth potential for faith-based investing on a global level, it is possible that this handicap might disappear.
