An Exploratory Study Investigating Leader and Follower Characteristics at U.S. Healthcare Organizations

Leadership has been studied by a myriad of scholars in the 20th and 21st centuries. One recent stream of research focuses on the followers of leaders. Today, followership is recognized as a construct that has value, and there is a broad call for additional research in this area (Gardner et al., 2005; Howell and Shamir, 2005.) In this study, the authors propose hypotheses that focus on followers and on their adoption of characteristics that are leader-like. The central thesis in this study is that followers have the ability to share roles with leaders. To test that thesis, a model is presented of specific leader and follower behaviors that (a) are thought to be related and overlapping, and (b) are relevant to role-sharing. Borrowing from prior work in which role sharing has been discussed, this study presents hypotheses and findings from analysis of field survey data collected from employees in healthcare organizations

Mending the Gaps: An Exercise in Identifying and Understanding Diverse and Multicultural Team Faultlines

The Faultlines Exercise, an experiential activity, introduces students to concepts of diversity attributes (surface and deep levels), social identity, and team faultlines. Through individual reflection and team discussion, students apply these concepts to their own diverse multicultural class teams with the goals of (a) preventing negative outcomes that may develop from faultlines and (b) improving team performance. Plenary class discussions reinforce key learning points that can be applied to teamwork throughout the course. Students in both face-to-face and online classes report that the exercise helps improve team performance and helps to identify and resolve problems. Instructions for facilitating classroom discussion and student handouts are provided, as are suggestions for adapting the exercise to other constructs

Most Admired Leader/Most Admired Follower

In introducing concepts of leadership and followership to students, this experiential exercise highlights qualities associated with the leader and follower roles. Various learning objectives guide the development of the exercise. They focus on identification of behavioral qualities possessed by both leaders and followers and on the importance of the leader-follower relationship to the organization’s achievement of goals. Theoretical underpinnings are stressed throughout. In the exercise, students individually develop a list of characteristics associated with their own most admired leader or follower and then share their lists in small groups. In plenary discussion, groups share all characteristics identified, and the instructor leads discussion to achieve stated learning objectives. Exercise handouts, instructions for facilitating classroom discussion, and a summary of theories that may be used as a postexercise student handout are provided

Relation between high-sensitivity C-reactive protein and cardiovascular and renal markers in a middle-income country in the African region.

BACKGROUND: High-sensitivity C-reactive protein (hs-CRP) is associated with several cardiovascular risk factors (CVRF) and with renal function markers. However, these associations have not been examined in populations in the African region. We analyzed the distribution of hs-CRP and the relationship with a broad set of CVRF, renal markers and carotid intima-media thickness (IMT), in the Seychelles (African region). METHODS: We conducted a survey in the population aged 25-64years (n=1255, participation rate: 80.2%). Analyses were restricted to persons of predominantly African descent (n=1011). RESULTS: Mean and median hs-CRP serum concentrations (mg/l) were 3.1 (SD 7.6) and 1.4 (IQR 0.7-2.9) in men and 4.5 (SD 6.7) and 2.2 (IQR 1.0-5.4) in women (p<0.001 for difference between men and women). hs-CRP was significantly associated with several conventional CVRF, and particularly strongly with markers of adiposity. With regards to renal markers, hs-CRP was strongly associated with cystatin C and with microalbuminuria but not with creatinine. hs-CRP was not associated with IMT. CONCLUSIONS: Serum concentration of hs-CRP was significantly associated with sex, several CVRF and selected renal function markers, which extends similar findings in Europe and in North America to a population in the African region. These findings can contribute to guide recommendations for the use of hs-CRP in clinical practice in the region

Use of electromyography to detect muscle exhaustion in finishing barrows fed ractopamine HCl

Use of electromyography to detect muscle exhaustion in finishing barrows fed ractopamine HCl. Journal of Animal Science, 94(6), 2344-2356. doi:10.2527/jas2016-0398The objectives of this study were to determine the effects of dietary ractopamine HCl (RAC) on muscle fiber characteristics and electromyography (EMG) measures of finishing barrow exhaustion when barrows were subjected to increased levels of activity. Barrows (n = 34; 92 +/- 2 kg initial BW) were assigned to 1 of 2 treatments: a conventional swine finishing diet containing 0 mg/kg ractopamine HCl (CON) or a diet formulated to meet the requirements of finishing barrows fed 10 mg/kg RAC (RAC+). After 32 d on feed, barrows were individually moved around a track at 0.79 m/s until subjectively exhausted. Wireless EMG sensors were affixed to the deltoideus (DT), triceps brachii lateral head (TLH), tensor fasciae latae (TFL), and semitendinosus (ST) muscles to measure median power frequency (MdPF) and root mean square (RMS) as indicators of action potential conduction velocity and muscle fiber recruitment, respectively. After harvest, samples of each muscle were collected for fiber type, succinate dehydrogenase (SDH), and capillary density analysis. Speed was not different (P = 0.82) between treatments, but RAC+ barrows reached subjective exhaustion earlier and covered less distance than CON barrows (P 0.29). There was a treatment x muscle interaction (P = 0.04) for end-point RMS values. The RAC diet did not change end-point RMS values in the DT or TLH (P > 0.37); however, the diet tended to decrease and increase end-point RMS in the ST and TFL, respectively (P 0.10). Muscles of RAC+ barrows tended to have less type I fibers and more capillaries per fiber (P < 0.07). Type I and IIA fibers of RAC+ barrows were larger (P < 0.07). Compared with all other muscles, the ST had more (P < 0.01) type IIB fibers and larger type I, IIA, and IIX fibers (P < 0.01). Type I, IIA, and IIX fibers of the ST also contained less SDH compared with the other muscles (P < 0.01). Barrows fed a RAC diet had increased time to subjective exhaustion due to loss of active muscle fibers in the ST, possibly due to fibers being larger and less oxidative in metabolism. Size increases in type I and IIA fibers with no change in oxidative capacity could also contribute to early exhaustion of RAC+ barrows. Overall, EMG technology can measure real-time muscle fiber loss to help explain subjective exhaustion in barrows

Prostaglandin treatment is associated with a withdrawal of progesterone and androgen at the receptor level in the uterine cervix

Treatment with prostaglandin(PG)-E2 is clinically efficient for cervical priming. The aim of this study was to evaluate the impact of PG-E2 on the expression of the progesterone (PR), androgen (AR) and glucocorticoid (GR) receptors in human uterine cervix in prolonged pregnancy
