Utilizing transformational leadership within nursing education: the impact on student learning and success
Transformational leadership has been proven to not only be effective in organizational settings but also within the educational realm. Nurse educators can use the principles of this leadership model in their practice to enhance student learning and success. Through inspirational motivation, idealized influence, individual consideration, and intellectual stimulation nurse educators can find guidance in moving their students forward to achieve the vision they have in becoming a nurse. Working in conjunction with the other three components, each aspect of transformational leadership is discussed in detail as well as how it relates to nursing education.
Key characteristics and strategies for educators to utilize are discussed as well as the phenomenon of academic incivility. Nurse educators are urged to be cognizant of this phenomenon and strategies to prevent and eliminate incivility are also discussed.

Leadership styles and personality variables: their effect on school performance
The purpose of this literature review, is to investigate the relationship between an educational leaders’ personality type and leadership style and their effect on school performance. Although leadership has been dissected and compared with personality in past literature, a scant amount of study (and information) has been conducted or is available, to support the theory of combinations of leadership styles and personality types. Multiple and current studies, have compartmentalized leadership style to transformational or transactional styles with the occasional obvious “no-fit” style to the previous to conduct relational research. Leadership is not relegated to only two styles. Styles change. Personality types, on the other hand, change in rare circumstances. Few studies have examined the variables of leadership style and personality types in current research. This literature review has the potential to lessen this gap by empirically studying these possible relationships. Implications and findings of this review could possibly identify links within existing leadership-personality literature as well as be helpful in guiding the development of future leaders at the instructional level.

A particular collection of service time distributions parameters study and impact in some M|G|∞ system busy period and busy cycle parameters
The problems arising when the moments of service time distributions, for which the M|G|∞ queue system busy period and busy cycle become very easy to study, are presented and it is shown how to overcome them. The busy cycle renewal function and the “peakedness” and the “modified peakedness” for the M|G|∞ busy period and busy cycle in the case of those service time distributions are also computed.

Traumatic brain injury: impact on veterans
Traumatic brain injury (TBI) is a frequent but under diagnosed condition that is associated with a number of comorbidities. It affects countless numbers of servicemen and women who were in combat in Iraq (Operation Iraqi Freedom) and Afghanistan (Operation Enduring Freedom). TBI is a disturbance of normal brain function that occurs when the head is suddenly thrust out of position. It can be a closed or open injury. It affects the ability to think effectively. TBI co-occurs with chronic pain, PTSD, and suicide. It is unique to the individual and can present with an array of different symptoms. The pain usually manifests as a headache, nociceptive pain, or neuropathic pain. This pain usually ranges from moderate to severe. Post traumatic disorder is the result of exposure to a severe stressor that threatens one’s life or physical integrity. OEF/OIF service members were exposed to high rates of trauma therefore developing Posttraumatic disorder. PTSD and depression are major mental health concerns for the patient diagnosed with traumatic brain injury. Traumatic brain injury in conjunction with chronic pain, PTSD and depression can be devastating. Veterans have a higher rate of suicide than the general population, therefore those with those with dual diagnoses are at highest risk. Clinical awareness is crucial in promoting overall well-being for these patients.

Chaos and complexity in the fisheries management context
Chaos Theory and nonlinear dynamic systems’ models huge importance is recognized beyond any kind of considerations in the most varied research fields. Chaos Theory contributes very significantly to the study of marine systems and fish stocks’ preservation. In this paper are presented clues to manage fisheries in view of chaos contextualization. Particularly, when applied in the situation of ecological systems, especially in the context of fisheries, highlights its recognition in the explanation of fishing phenomena.
