Sample records for wing leadership exploring

  1. Exploration of transformational and distributed leadership. (United States)

    Tomlinson, Julie


    Throughout government policy in Scotland, a new emphasis has been placed on clinical leaders as a way to improve quality and restore the public's confidence in health care. This article reports on a study that explored the leadership styles of senior charge nurses and the effects these may have on clinical teams. Findings suggest that, where there is transformational leadership and sharing of leadership roles across teams, staff are more engaged and organisational goals are met. The findings also highlight the need for better communication between senior management and clinical teams to ensure sustainable, good services.

  2. Exploring Nurse Faculty Incivility and Resonant Leadership. (United States)

    Casale, Katherine R

    The purpose of this quantitative correlational study was to explore the relationship between the frequency of interfaculty incivility among nurses in academia and observed levels of resonant leadership of immediate supervisors. Despite mandates to address incivility in health care, nurse faculty report high levels of horizontal incivility among their peers. No known quantitative research has measured the relationship between nurse faculty-to-faculty incivility and resonant leadership traits of leaders. Nursing faculty from 17 universities (n = 260) were emailed an anonymous link to answer survey questions about horizontal peer incivility and leaders' management styles. There was a significant inverse relationship (Pearson's r, -.560) between the frequency of experienced faculty-to-faculty incivility and the level of observed resonant leadership behaviors of participants' immediate supervisors. Resonant supervisory behaviors inversely correlated with nurse faculty peer incivility, with potential to impact satisfaction, recruitment, and retention.

  3. Exploring female GPs' perceptions about medical leadership. (United States)

    Price, Karen; Clearihan, Lynette


    Women are increasingly entering the Australian general practice workforce. This study aims to explore female general practitioners' (GPs') perceptions of possible barriers to leadership and professional roles in the workforce. A purposive, convenience sample of 30 female GPs in active practice was approached in February, 2012. An anonymous, pa-per-based, semi-quantitative survey sought to identify participation and leadership confidence within general practice in a number of professional roles. The top two barriers participants identified for after-hours medical meetings were energy to attend and geographical location. For after-hours care, the top two barriers identified were energy and self-motivation. Few participants aspired to 'leadership' activities. 'Medical mentoring' was most likely to attract them into leadership. It is important female GPs' perspectives are explored in general practice. This small survey suggests further studies are needed in the importance of energy limitations and lack of self-confidence in restricting female GPs' capacity to fully engage in professional roles.

  4. Fixed-Wing UAVs Flock Control through Cohesion and Repulsion Behaviours Combined with a Leadership

    Directory of Open Access Journals (Sweden)

    Cezary Kownacki


    Full Text Available The aim of this paper is to present a novel approach to swarm control of small fixed-wing UAVs, which combines only two flocking behaviours with a leadership feature. In the presented approach, two fundamental rules of Reynolds flocking are applied, i.e., cohesion and repulsion, as the base of a decentralized control of self-organization of the flock. These rules are combined with a leadership feature, which is responsible for a global behaviour of guidance, as in the case of animals. Such a bio-inspired combination allows the achievement of a coherent collective flight of a flock of fixed-wing UAVs without applying formal behaviours of migration and alignment. This highly simplifies an implementation of the algorithm. The presented results include both numerical simulations and experimental flights, which validate the hardware implementation of the approach.

  5. An exploration of two perspectives on global leadership and the potential consequences for global leadership development


    Rønning, Rune; Espedal, Bjarne; Jordahl, Atle


    The paper explores two logics of global leadership; the logic of instrumentality and the logic of appropriateness. These two logics and their relation to multinational enterprises are traced in organizational theory and in global leadership theory and the consequences of the two logics for the design of global leadership development programs are explored. It is argued that applying a logic of instrumentality uncritically to global leadership in multinational enterprises is potentially fraught...

  6. Developing leadership in nursing: exploring core factors. (United States)

    Curtis, Elizabeth A; de Vries, Jan; Sheerin, Fintan K

    This article provides an introduction to the issue of nursing leadership, addressing definitions and theories underpinning leadership, factors that enhance leadership in nursing, and the nature of leadership content taught in undergraduate programmes. Highlighted are differences between leadership and management, and the notion that leadership can be 'learned'. The authors also point out that there is a discrepancy between how leading undergraduate nursing programmes prepare students primarily in the transition of education to practice, and the suggestion from a number of nursing publications that leadership in nurses should be fostered throughout their education.

  7. Exploring leadership styles for innovation: an exploratory factor analysis

    Directory of Open Access Journals (Sweden)

    Wipulanusat Warit


    Full Text Available Leadership plays a vital role in building the process, structures, and climate for an organisation to become innovative and to motivate team expectations toward innovations. This study explores the leadership styles that engineers regard as significant for innovation in the public sector. Exploratory factor analysis (EFA was conducted to identify the principal leadership styles influencing innovation in the Australian Public Service (APS, using survey data extracted from the 2014 APS employee census comprising 3 125 engineering professionals in Commonwealth of Australia departments. EFA returned a two-factor structure explaining 77.6% of the variance of the leadership for innovation construct. In this study, the results from the EFA provided a clear estimation of the factor structure of the measures for leadership for innovation. From the results, the two factors extracted were transformational leadership and consideration leadership. In transformational leadership, a leader values organisational objectives, inspires subordinates to perform, and motivates followers beyond expected levels of work standards. Consideration leadership refers to the degree to which a leader shows concern and expressions of support for subordinates, takes care of their welfare, treats members as equals, and displays warmth and approachability. These findings highlight the role of leadership as the most critical predictor when considering the degree to which subordinates strive for creativity and innovation. Both transformational and consideration leadership styles are recommended to be incorporated into management training and development programs. This study also recommends that Commonwealth departments recruit supervisors who have both of these leadership styles before implementing innovative projects.

  8. Clinical leadership and nursing explored: A literature search. (United States)

    Stanley, David; Stanley, Karen


    To explore what we know of the concept of clinical leadership and what the term means. Clues to the definition of clinical leadership, the attributes of effective and less effective clinical leaders, models of clinical leadership and the barriers that hinder clinical leadership development were explored. While nursing leadership and healthcare leadership are terms that have been evident in nursing and health industry literature for many decades, clinical leadership is a relatively new term and is may still be misunderstood. A search was undertaken of formal and informal literature using a library database and a range of search engines for the words "clinical leadership" and "clinical leadership in nursing." In each case, the full search parameters were employed with searches between 1974-2016. Full-text articles were requested, and English was the preferred language. In total, 3,259 publications were located through seven database search tools, although these included a large number of duplications. Following further informal searches and removing irrelevant material, 27 research or literature review focused papers were retained that included 17 qualitative studies, one quantitative study, one mixed method study, one Delphi study and two that compared other research studies. As well, five literature reviews were retained in the synthesis. The data synthesis resulted five categories: definitions of clinical leadership, characteristics most likely or least associated with clinical leadership, models applied to clinical leadership and limits to clinical leadership development. Clinical leaders are recognised for having their values and beliefs parallel their actions and interventions. They are found across the spectrum of health organisations, often at the highest level for clinical interaction, but not commonly at the highest management level in a ward or unit team and they are seen in all clinical environments. Clinical Leadership and an understanding on how

  12. Exploring leadership in community nursing teams. (United States)

    Cameron, Shona; Harbison, Jean; Lambert, Vicky; Dickson, Caroline


    This article is a report on a study investigating how leadership is perceived in community nursing teams and how these perceptions are translated into working practices of team leaders. The consensus in community nursing literature is that leadership is important, and especially so in a time of change. However, little empirical evidence exists on how leadership works in practice. The study adopted an exploratory descriptive design, utilising individual semi-structured interviews and focus groups in four case-studies, with a total of 54 participants. Two case-studies focussed on district nursing teams and two involved public health nursing teams, located in two geographical areas. Participants debated their understanding of the concept of leadership, its associated practices and behaviours in teams, if they saw themselves as leaders, and what preparation was required. The study was undertaken in 2009. Framework analysis techniques were employed to analyse the data. A 'quasi-family' model of leadership emerged, with significant emphasis on the importance of personal relationships and support. Nursing grade had a greater impact on perceptions of leadership than geographical context or professional and clinical focus. No clear fit with any existing theoretical framework was identified. However, nurses in the highest grade banding, in particular, demonstrated practices associated with transformational leadership. Nurses expressed the very clear need to be acknowledged, respected and valued, and that those who provided this support were regarded as good leaders. © 2011 Blackwell Publishing Ltd.

  14. Exploring a shared leadership perspective for NHS doctors. (United States)

    Willcocks, Stephen George; Wibberley, Gemma


    The purpose of this paper is to explore involving doctors in shared leadership. It examines the policies that have led to the focus on shared leadership and the implications for practice. This is a conceptual paper, examining policy developments and key literature to understand the move towards shared leadership. It focuses on UK NHS, and in particular doctors, although the concepts will be relevant to other disciplines in healthcare, and healthcare systems in other countries. This paper suggests that the shared-leadership approach for doctors has potential given the nature of clinical practice, the inherently collaborative nature of healthcare and the demands of new healthcare organisations. Health policy reform, generally, will mean that all doctors need to be engaged with leadership, albeit, perhaps, at different levels, and with different degrees of formality. Leadership will remain an important precondition for the success of the reforms. This is likely to be the case for other countries involved in healthcare reform. To highlight the benefits and barriers to shared leadership for doctors. Offers an alternative to traditional approaches to leadership.

  15. Exploring leadership in the context of dentistry in the UK. (United States)

    Willcocks, Stephen George


    Purpose The purpose of this paper is to explore selective leadership approaches in the context of dentistry in the UK. Design/methodology/approach This is a conceptual paper utilising published sources from relevant literature about leadership theory and practice and the policy background to dentistry in the UK. Findings This paper suggests that there is merit in identifying and applying an eclectic mix of leadership theory to the case of dentistry. It offers insight into individual aspects of the leadership role for dentists and applies this to the dental context. It also contrasts these individual approaches with shared leadership and suggests this may also be relevant to dentistry. It highlights the fact that leadership will be of growing concern for dentistry in the light of recent policy changes. Research limitations/implications This paper points out that there are developmental implications depending on the particular approach taken. It argues that leadership development will become increasingly important in dentistry in the UK. Originality/value This paper addresses a topic that has so far received limited attention in the literature.

    Oandasan, Ivy; White, David; Hammond Mobilio, Melanie; Gotlib Conn, Lesley; Feldman, Kymm; Kim, Florence; Rouleau, Katherine; Sorensen, Leslie


    To explore how family physicians understand the concept of academic leadership. Case study. Department of Family and Community Medicine at the University of Toronto in Ontario. Thirty family physician academic leaders. Focus groups and interviews were conducted with family physicians from a large multisite urban university who were identified by peers as academic leaders at various career stages. Transcripts from the focus groups and interviews were anonymized and themes were analyzed and negotiated among 3 researchers. Participants identified qualities of leadership among academic leaders that align with those identified in the current literature. Despite being identified by others as academic leaders, participants were reluctant to self-identify as such. Participants believed they had taken on early leadership roles by default rather than through planned career development. This study affirms the need to define academic leadership explicitly, advance a culture that supports it, and nurture leaders at all levels with a variety of strategies.

    Full Text Available Leadership style is considered an important factor that influences the firm perfomance. The aim of the present paper is to explore the correlations between the gender and management level of the managers, considered as independent variables, and the managers leadership styles as dependent variables. The study was based on an empirical research undertaken on a representative sample of 80 managers from different hierarchical levels in Romanian software development companies. The research methodology involved a design of two hypotheses, tested by means of Pearson chi-square. The research results emphasize a cultural specific context and some suggestions for future research are provided.

  19. Exploration of the rotational power consumption of a rigid flapping wing (United States)

    Truppel, Michael; Rossi, Lionel


    The development of Micro Air Vehicles with flapping wings is inspired from the observation and study of natural flyers such as insects and birds. This article explores the rotational power consumption of a flapping wing using a mechanical flapper at Re ≃ 4,500. This mechanical flapper is simplified to a 2D translation and a rotation in a water tank. Moreover, the wing kinematics are reduced to a linear translation and a rotation for the purpose of our study. We introduce the notion of non-ideal flapper and associated non-ideal rotational power. Such non-ideal devices are defined as consuming power for adding and removing mechanical power to and from the flow, respectively. First, we use a traditional symmetrical wing kinematic which is a simplified kinematic inspired from natural flyers. The lift coefficient of this flapping is about C L ≃ 1.5. This symmetrical wing kinematic is chosen as a reference. Further, wing kinematics with asymmetric rotations are then compared with this one. These new kinematics are built using a differential velocity defined according to the translational kinematics, a time lag and a distance, r kp. The analogy of this distance is discussed as a key point to follow along the chord. First, the wing kinematics are varied keeping a similar shape for the profiles of the angular velocity. It is shown that when compared to the reference wing kinematic, a 10% reduction in the rotational power is obtained whilst the lift is reduced by 9%. Second, we release the limitation to a similar shape for the profiles of the angular velocity leading to a novel shape for the angular velocity profile named here as "double bump" profile. With these new wing kinematics, we show that a 60% reduction in the non-ideal rotational power can be achieved whilst the lift coefficient is only reduced by 1.7%. Such "double bump kinematics" could then be of interest to increase the endurance of Micro Air Vehicles.

  1. Exploring the learnings derived from catalytic experiences in a leadership context

    Directory of Open Access Journals (Sweden)

    Daphna S. Horowitz


    Full Text Available Orientation: Personal leadership comprises self-awareness, authenticity, inspiration and passion. The concept of personal leadership was explored together with its relationship with leadership-related learnings derived from a catalytic experience. Research purpose: The objective of the study was to explore the leadership-related learnings derived from a catalytic experience and any connection between these learnings, personal leadership and leadership in an organisational context. Motivation for the study: Measurement of leaders’ performance remains largely focused on the results achieved. The importance of personal leadership in the corporate environment is often ignored and even questioned. Recognising that there is a relationship between personal leadership and professional leadership enables leaders to connect who they are being and what they are doing. This can enhance their leadership. Research design, approach and method: The study was conducted using a qualitative approach, specifically narrative enquiry. The sample comprised seven leaders who have had catalytic experiences in their lives. In-depth interviews were conducted and thematic analysis was used to identify themes on the leadership-related learnings gained from the leaders’catalytic experiences. Main findings: Elements of personal leadership and the processes involved in the development of personal leadership were identified. It was furthermore shown that challenging experiences serve as learning opportunities and that time for reflection is essential in this learning process. Practical/managerial implications: Leadership lessons are best learnt through experience.Using challenging experiences as learning opportunities may assist leaders in their growth and development. Contribution: Leadership effectiveness and organisational effectiveness may be enhanced by a more holistic view of leadership that includes elements of personal leadership.

  2. Exploring leadership in self-managed project teams in Malaysia

    Directory of Open Access Journals (Sweden)

    Zaleha Yazid


    Full Text Available This paper focuses on a longitudinal approach in exploring leadership in Self-Managed Project Teams (SMPT. SMPT has been known to contribute to organizations by improving productivity and increasing organizational performance. Therefore, understanding the dynamics of leadership in this type of team can be seen as one of the important factors to ensure the success of organizations. Leading a team which manages itself is a challenge as increased autonomy and control is given to the team which eliminates the existence of a leader. It is important to understand the extent of how the external leader is involved within SMPT and whether the external leader approaches highlighted in the literature are applicable in such a situation and how these approaches change during work processes. This study comprises of evidence collected through semi-structured interviews in two small and medium sized organizations in Malaysia. Weekly telephone interviews as well as face-to-face interviews were conducted which provides contextual data for the research. In this research, the evidence suggested that SMPT transform from self-managed toward leader-managed resulting from several factors, such as conflict handling strategies. Specifically, it was found that avoiding conflicts, rather than confronting, transform the team into being leader dependent.

  1. Job strain in nursing homes-Exploring the impact of leadership. (United States)

    Backman, Annica; Sjögren, Karin; Lövheim, Hugo; Edvardsson, David


    To explore the association between nursing home managers' leadership, job strain and social support as perceived by direct care staff in nursing homes. It is well known that aged care staff experience high levels of job strain, and that aged care staff experiencing job strain are exposed to increased risk for adverse health effects. Leadership styles have been associated with job strain in the literature; however, the impact of perceived leadership on staff job strain and social support has not been clarified within nursing home contexts. This study had a cross-sectional design. Participating staff (n = 3,605) completed surveys which included questions about staff characteristics, valid and reliable measures of nursing home managers' leadership, perceived job strain and social support. Statistical analyses of correlations and multiple regression analysis with interaction terms were conducted. Nursing home managers' leadership were significantly associated with lower level of job strain and higher level of social support among direct care staff. A multiple regression analysis including an interaction term indicated individual and joint effects of nursing home managers' leadership and social support on job strain. Nursing home managers' leadership and social support were both individually and in combination associated with staff perception of lesser job strain. Thus, nursing home managers' leadership are beneficial for the working situation and strain of staff. Promoting a supporting work environment through leadership is an important implication for nursing home managers as it can influence staff perception of job strain and social support within the unit. By providing leadership, offering support and strategies towards a healthy work environment, nursing home managers can buffer adverse health effects among staff. © 2018 John Wiley & Sons Ltd.

  3. Exploring the impact of transformational leadership on nurse innovation behaviour: a cross-sectional study. (United States)

    Weng, Rhay-Hung; Huang, Ching-Yuan; Chen, Li-Mei; Chang, Li-Yu


    This study explored the influences of transformational leadership on nurse innovation behaviour and the mediating role of organisational climate. Recently, global nursing experts have been aggressively encouraging nurses to pursue innovation in nursing in order to improve nursing outcomes. Nursing innovation, in turn, is affected by nursing leadership. We employed a questionnaire survey to collect data, and selected a sample of nurses from hospitals in Taiwan. A total of 439 valid surveys were obtained. Hierarchical multiple regression model analysis was conducted to test the study hypothesis. The mean values of agreement of nurse innovation behaviour and transformational leadership were 3.40 and 3.78, respectively. Patient safety climate and innovation climate were found to have full mediating effects on the relationship between transformational leadership and innovation behaviour. Organisational climate has a significant impact on innovation behaviour. Transformational leadership has indirect effects on innovation behaviour via the mediation of patient safety climate and innovation climate. Hospitals should enhance transformational leadership by designing leadership training programmes and establishing transformational culture. In addition, nursing managers should foster nursing innovation through improvements in organisational climate. © 2013 John Wiley & Sons Ltd.

  4. Leadership and followership in the healthcare workplace: exploring medical trainees’ experiences through narrative inquiry (United States)

    Gordon, Lisi J; Rees, Charlotte E; Ker, Jean S; Cleland, Jennifer


    Objectives To explore medical trainees’ experiences of leadership and followership in the interprofessional healthcare workplace. Design A qualitative approach using narrative interviewing techniques in 11 group and 19 individual interviews with UK medical trainees. Setting Multisite study across four UK health boards. Participants Through maximum variation sampling, 65 medical trainees were recruited from a range of specialties and at various stages of training. Participants shared stories about their experiences of leadership and followership in the healthcare workplace. Methods Data were analysed using thematic and narrative analysis. Results We identified 171 personal incident narratives about leadership and followership. Participants most often narrated experiences from the position of follower. Their narratives illustrated many factors that facilitate or inhibit developing leadership identities; that traditional medical and interprofessional hierarchies persist within the healthcare workplace; and that wider healthcare systems can act as barriers to distributed leadership practices. Conclusions This paper provides new understandings of the multiple ways in which leadership and followership is experienced in the healthcare workplace and sets out recommendations for future leadership educational practices and research.

  5. Towards person-centredness in aged care - exploring the impact of leadership. (United States)

    Backman, Annica; Sjögren, Karin; Lindkvist, Marie; Lövheim, Hugo; Edvardsson, David


    To explore the association between leadership behaviours among managers in aged care, and person-centredness of care and the psychosocial climate. Theory suggests that leadership is important for improving person-centredness in aged care, however, empirical evidence is lacking. A cross-sectional design was used to collect data from Swedish aged care staff (n = 3661). Valid and reliable questionnaires assessing leadership behaviours, person-centeredness of care and the psychosocial climate were used. Data were analysed using multiple linear regression including interaction terms. Leadership behaviours were significantly related to the person-centredness of care and the psychosocial climate. The level of person-centredness of care moderated the impact of leadership on the psychosocial climate. The leadership behaviour of managers significantly impacts person-centred care practice and contributes to the psychosocial climate for both staff and residents in aged care. This study is the first empirically to confirm that middle managers have a central leadership role in developing and supporting person-centred care practice, thereby creating a positive psychosocial climate and high quality care. © 2016 John Wiley & Sons Ltd.

  6. Exploring team working and shared leadership in multi-disciplinary cancer care. (United States)

    Willcocks, Stephen George


    Purpose The purpose of this paper is to explore the relevance of shared leadership to multi-disciplinary cancer care. It examines the policy background and applies concepts from shared leadership to this context. It includes discussion of the implications and recommendations. Design/methodology/approach This is a conceptual paper examining policy documents and secondary literature on the topic. While it focuses on the UK National Health Services, it is also relevant to other countries given they follow a broadly similar path with regard to multi-disciplinary working. Findings The paper suggests that shared leadership is a possible way forward for multi-disciplinary cancer care, particularly as policy developments are supportive of this. It shows that a shared perspective is likely to be beneficial to the further development of multi-disciplinary working. Research limitations/implications Adopting shared leadership needs to be explored further using appropriate empirical research. Practical implications The paper offers comments on the implications of introducing shared leadership and makes recommendations including being aware of the barriers to its implementation. Originality/value The paper offers an alternative view on leadership in the health-care context.

  7. Exploring the Role of Habitat on the Wettability of Cicada Wings. (United States)

    Oh, Junho; Dana, Catherine E; Hong, Sungmin; Román, Jessica K; Jo, Kyoo Dong; Hong, Je Won; Nguyen, Jonah; Cropek, Donald M; Alleyne, Marianne; Miljkovic, Nenad


    Evolutionary pressure has pushed many extant species to develop micro/nanostructures that can significantly affect wettability and enable functionalities such as droplet jumping, self-cleaning, antifogging, antimicrobial, and antireflectivity. In particular, significant effort is underway to understand the insect wing surface structure to establish rational design tools for the development of novel engineered materials. Most studies, however, have focused on superhydrophobic wings obtained from a single insect species, in particular, the Psaltoda claripennis cicada. Here, we investigate the relationship between the spatially dependent wing wettability, topology, and droplet jumping behavior of multiple cicada species and their habitat, lifecycle, and interspecies relatedness. We focus on cicada wings of four different species: Neotibicen pruinosus, N. tibicen, Megatibicen dorsatus, and Magicicada septendecim and take a comparative approach. Using spatially resolved microgoniometry, scanning electron microscopy, atomic force microscopy, and high speed optical microscopy, we show that within cicada species, the wettability of wings is spatially homogeneous across wing cells. All four species were shown to have truncated conical pillars with widely varying length scales ranging from 50 to 400 nm in height. Comparison of the wettability revealed three cicada species with wings that are superhydrophobic (>150°) with low contact angle hysteresis (water shedding behavior but also enables the development of rational design tools for the manufacture of artificial surfaces for energy and water applications.

  17. Exploring leadership capability and emotional intelligence as moderators of workplace bullying. (United States)

    Hutchinson, Marie; Hurley, John


    This study aimed to explore the potential for emotionally intelligent leadership as a way to mitigate bullying behaviour within nursing workplace environments. As the body of evidence about bullying continues to grow there is an increasing need for researchers to direct their attention to developing theoretical frameworks that explain how bullying and victimization occur, and the types of strategies that may address the problem. The narrative synthesis of the literature presented in this paper is forwarded as supporting the need for strengthening leadership capability, especially those capabilities associated with emotional intelligence, as a means of diminishing experienced bullying within nursing. Stemming from our expanding understandings about bullying is an appreciation of the range of factors within organizations that influence the occurrence of bullying, and an awareness of the need to understand the expression, experience and management of emotions in the workplace. While both leadership and emotional intelligence capabilities offer real potential to mitigate bullying behaviour, disparity exits between clinical and managerial nurses toward preferred leadership styles and emotional intelligence is open to challenges towards its content validity. Nursing management is challenged to build upon procedural responses to bullying to include a ground up approach to leadership enhancement capability, better responses to emotions in the workplace and supporting the interpersonal and intrapersonal capabilities of the nursing workforce. © 2012 Blackwell Publishing Ltd.

    Full Text Available In organizational research and practice, prolific communication is significantly linked with quality leadership traits. Leadership quality helps in mitigating the failure of an organization to survive the increasing business challenges that may result in waste of resources, talents and potentials needed for achieving optimal organizational productivity. However, an examination of academic literatures reveal that corporate leaders are often faced with the challenge of how to move smoothly between different communication styles to communicate clearly articulating ideas and knowledge to employee’s whenever the occasion demands which hinders organizational productivity. Against this background, this study explores the relationship between leadership communication style, personality trait and organizational productivity. The study utilized cross-sectional survey method. Participants were 112 academic staff of University of Lagos, Nigeria who was selected through multi-stage sampling techniques. Data were collected through structured questionnaire and personal observation. Results show that there exists a connection between leadership communication style and personality trait. Also, the finding revealed that leadership communication style determines organization productivity. More so, the finding established that personality traits and communication styles have combine effect on organizational productivity. Conclusively, the findings were discussed with reference to relevant empirical literatures with recommendations for management of organizations both for practice and future research highlighted.

  19. Exploring the nature and impact of leadership on the local implementation of the Productive Ward Releasing Time to Care. (United States)

    Morrow, Elizabeth; Robert, Glenn; Maben, Jill


    The purpose of this paper is to explore the nature and impact of leadership in relation to the local implementation of quality improvement interventions in health care organisations. Using empirical data from two studies of the implementation of The Productive Ward: Releasing Time to Care in English hospitals, the paper explores leadership in relation to local implementation. Data were attained from in-depth interviews with senior managers, middle managers and frontline staff (n = 79) in 13 NHS hospital case study sites. Framework Approach was used to explore staff views and to identify themes about leadership. Four overall themes were identified: different leadership roles at multiple levels of the organisation, experiences of "good and bad" leadership styles, frontline staff having a sense of permission to lead change, leader's actions to spread learning and sustain improvements. This paper offers useful perspectives in understanding informal, emergent, developmental or shared "new" leadership because it emphasises that health care structures, systems and processes influence and shape interactions between the people who work within them. The framework of leadership processes developed could guide implementing organisations to achieve leadership at multiple levels, use appropriate leadership roles, styles and behaviours at different levels and stages of implementation, value and provide support for meaningful staff empowerment, and enable leader's boundary spanning activities to spread learning and sustain improvements.

  5. Subsonic Ultra Green Aircraft Research. Phase II - Volume I; Truss Braced Wing Design Exploration (United States)

    Bradley, Marty K.; Droney, Christopher K.; Allen, Timothy J.


    This report summarizes the Truss Braced Wing (TBW) work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, consisting of Boeing Research and Technology, Boeing Commercial Airplanes, General Electric, Georgia Tech, Virginia Tech, NextGen Aeronautics, and Microcraft. A multi-disciplinary optimization (MDO) environment defined the geometry that was further refined for the updated SUGAR High TBW configuration. Airfoil shapes were tested in the NASA TCT facility, and an aeroelastic model was tested in the NASA TDT facility. Flutter suppression was successfully demonstrated using control laws derived from test system ID data and analysis models. Aeroelastic impacts for the TBW design are manageable and smaller than assumed in Phase I. Flutter analysis of TBW designs need to include pre-load and large displacement non-linear effects to obtain a reasonable match to test data. With the updated performance and sizing, fuel burn and energy use is reduced by 54% compared to the SUGAR Free current technology Baseline (Goal 60%). Use of the unducted fan version of the engine reduces fuel burn and energy by 56% compared to the Baseline. Technology development roadmaps were updated, and an airport compatibility analysis established feasibility of a folding wing aircraft at existing airports.

  6. Scaling of Hybrid Wing-Body-Type Aircraft: Exploration Through High-Fidelity Aerodynamic Shape Optimization (United States)

    Reist, Thomas A.

    Unconventional aircraft configurations have the potential to reduce aviation's contribution to climate change through substantial reductions in fuel burn. One promising configuration which has received much attention is the hybrid wing-body (HWB). Due to the lack of design experience for unconventional configurations, high-fidelity design and optimization methods will be critical in their development. This thesis presents the application of a gradient-based aerodynamic shape optimization algorithm based on the Reynolds-averaged Navier-Stokes equations to the aerodynamic design of conventional tube-and-wing (CTW) and HWB aircraft. The optimal aerodynamic shapes and performance for a range of aircraft sizes including regional, narrow-body, midsize, and wide-body classes are found so as to characterize the aerodynamic efficiency benefits of the HWB configuration with respect to equivalent CTW designs. Trim-constrained drag minimization is performed at cruise, with a large design space of over 400 design variables. The smaller optimized HWBs, including the regional and narrow-body classes, while more aerodynamically efficient, burn at least as much fuel as to the equivalently optimized CTWs due to their increased weight, while the larger wide-body-class HWB has almost 11% lower cruise fuel burn. To investigate alternative configurations which may yield improved efficiency, exploratory optimizations with significant geometric freedom are then performed, resulting in a set of novel shapes with a more slender lifting fuselage and distinct wings. Based on these exploratory results, new lifting-fuselage configurations (LFCs) are designed. The slenderness of the LFC fuselage decreases with aircraft size, such that, for the largest class, the LFC reverts to a classical HWB shape. This new configuration offers higher aerodynamic efficiency than the HWBs, with the smaller classes seeing the largest benefit from the new configuration. This new lifting-fuselage concept offers 6

  7. Spiritual character traits and leadership in the school workplace: An exploration of the relationship between spirituality and school leadership in some private and religiously affiliated schools in South Africa

    Directory of Open Access Journals (Sweden)

    Jaco S. Dreyer


    Full Text Available The South African educational system is in a crisis. This situation places huge demands on school principals and school management teams, and raises many theoretical and empirical questions. Transformational leadership is needed to deal with these challenges and complexities. Not all school leaders show the same level of transformational leadership. Some leaders conform more to other leadership styles. The aim of this article is to explore the relation between spiritual character traits and leadership styles from a theoretical and empirical perspective. The theoretical part focuses on the conceptualisation of leadership (styles and spirituality. The empirical research consists of a web-based survey conducted in some private and religiously affiliated schools in South Africa in 2011–2012. The Multifactor Leadership Questionnaire (MLQ and Cloninger’s shortened Temperament and Character Inventory (TCI-140 were used to measure leadership styles and spiritual traits respectively. Statistical procedures included confirmatory factor analysis, correlation (Pearson rho and regression analysis. Key findings are that leaders of private schools in South Africa mostly conform to a transformative leadership style, disagree with corrective leadership and strongly disagree with passive-avoidant leadership. Regarding the spiritual character traits they agree with self-transcendence and strongly agree with self-directedness. Spiritual character traits are strong predictors for transformational and passive-avoidant leadership. Higher levels of self-transcendence and self-directedness are strong predictors for transformational leadership. Our research suggests that traditional religious variables are less important as predictors of leadership style than spiritual character traits.

  10. CO2Explorer: Conducting Greenhouse-Gas Measurements of Landfills using a Small Fixed-wing UAV (United States)

    Hollingsworth, Peter; Allen, Grant; Kabbabe, Khristopher; Pitt, Joseph


    Quantifying inventories of Greenhouse gas emissions, primarily Methane and Carbon Dioxide, from distributed sources such as a landfill has historically been undertaken using one of several ground based measurement techniques. These methods are either time and/or resource intensive. As a result regulatory agencies have started looking at the potential of using small-unmanned aircraft to supplement or supplant the current methods. The challenge of using a UAV to perform these tasks is the trade-off between accuracy, operational flexibility and operational productivity. This is driven by the state-of-the-art in measurement instruments, the operating environment at landfills and the regulatory/safety environment surrounding UAV operations. This work describes the development of the operational concept, and associated UAV measurement platform for the CO2Explorer. It looks at the scientific, engineering and possible policy trades and compares the use of small rotary and fixed-wing UAVs from both an operational and measurement perspective. This work also makes recommendations on system development and operation for users lacking in both systems engineering and operational experience.

  14. Exploring the Relationship of Organizational Culture and Implicit Leadership Theory to Performance Differences in the Nuclear and Fossil Energy Industry (United States)

    Cravey, Kristopher J.

    Notable performance differences exist between nuclear and fossil power generation plants in areas such as safety, outage duration efficiency, and capacity factor. This study explored the relationship of organizational culture and implicit leadership theory to these performance differences. A mixed methods approach consisting of quantitative instruments, namely the Organizational Culture Assessment Instrument and the GLOBE Leadership Scales, and qualitative interviews were used in this study. Subjects were operations middle managers in a U.S. energy company that serves nuclear or fossil power plants. Results from the quantitative instruments revealed no differences between nuclear and fossil groups in regards to organizational culture types and implicit leadership theories. However, the qualitative results did reveal divergence between the two groups in regards to what is valued in the organization and how that drives behaviors and decision making. These organizational phenomenological differences seem to explain why performance differences exist between nuclear and fossil plants because, ultimately, they affect how the organization functions.

  15. Exploring the impacts of personal factors on self-leadership in a hospital setting. (United States)

    Ugurluoglu, Ozgur; Saygılı, Meltem; Ozer, Ozlem; Santas, Fatih


    Self-leadership may be defined as a self-effecting process that individuals experience by maintaining the motivation they require for fulfilling their roles and duties. The self-leadership process comprises three key strategies: behaviour-oriented strategies, natural reward strategies and constructive thought pattern strategies. What is intended herein is to inquire about the implementation of self-leadership within organisations and to examine the effects of such variables as age, gender, total terms of employment, marital status and education on self-leadership strategies. The primary data collection instrument was a survey distributed to 450 personnel working at a state hospital in Kırıkkale, Turkey, and feedback thereto was received from 308 (68.4%) of those surveyed. As a result of the findings taken from the analyses, age, total terms of employment and receipt of education in leadership affect the use of self-leadership strategies. Although age and total terms of employment display a negative-directional correlation with the self-leadership strategies, female employees and those who receive education in leadership are more inclined towards self-leadership strategies.

  2. Effect of outer wing separation on lift and thrust generation in a flapping wing system

    International Nuclear Information System (INIS)

    Mahardika, Nanang; Viet, Nguyen Quoc; Park, Hoon Cheol


    We explore the implementation of wing feather separation and lead-lagging motion to a flapping wing. A biomimetic flapping wing system with separated outer wings is designed and demonstrated. The artificial wing feather separation is implemented in the biomimetic wing by dividing the wing into inner and outer wings. The features of flapping, lead-lagging, and outer wing separation of the flapping wing system are captured by a high-speed camera for evaluation. The performance of the flapping wing system with separated outer wings is compared to that of a flapping wing system with closed outer wings in terms of forward force and downward force production. For a low flapping frequency ranging from 2.47 to 3.90 Hz, the proposed biomimetic flapping wing system shows a higher thrust and lift generation capability as demonstrated by a series of experiments. For 1.6 V application (lower frequency operation), the flapping wing system with separated wings could generate about 56% higher forward force and about 61% less downward force compared to that with closed wings, which is enough to demonstrate larger thrust and lift production capability of the separated outer wings. The experiments show that the outer parts of the separated wings are able to deform, resulting in a smaller amount of drag production during the upstroke, while still producing relatively greater lift and thrust during the downstroke.

  3. Cognitive styles in creative leadership practices: exploring the relationship between level and style. (United States)

    Isaksen, Scott G; Babij, Barbara J; Lauer, Kenneth J


    This study investigated the relationship between two measures used to assist change and transformation efforts, the Kirton Adaption-Innovation Inventory which assesses style or manner of cognition and problem-solving, not level or capability, and the Leadership Practices Inventory which measures the extent to which leaders exhibit certain leadership behaviors associated with accomplishing extraordinary results. These two measures of level and style should be conceptually distinct and show no or only modest correlation. Analysis yielded statistically significant and meaningful relationships between scores on the Kirton inventory and two scales of the Leadership Practices Inventory. Implications and challenges for research and practice were outlined.

  5. Exploring leadership and team communication within the organizational environment of a dental practice. (United States)

    Chilcutt, Alexa Stough


    A lack of training in leadership and communication skills can place dentists at a disadvantage, leading to high degrees of staff-related stress and turnover. A dentist's leadership style directly affects an office's communication practices, and specific leadership behaviors affect the degree of team identity, interdependence and social distance (a measure of the influential power of team members). The author recruited 10 dental offices to take part in a study. Qualitative methods included in-depth interviews of one dentist, one senior staff member and one newer staff member from each office. The interview findings show that clear and definable relationships exist between leadership behaviors--hierarchical or team-oriented organizational perspectives, proactive or laissez-faire leadership styles, and autocratic or participative decision-making processes--and the team's communication practices. Decision-making processes directly affect the degree of team identification experienced by staff members, and conflict-management tactics affect team members' sense of interdependence and social distance. The findings of this study indicate that dentists should engage in participative decision-making processes that include staff members, thereby communicating their value to the practice and empowering employees. They also must become proactive in facilitating an environment that encourages collaboration and confrontation as healthy forms of conflict management. These leadership and communication behaviors are the most significant in creating a real rather than nominal team culture, which, in turn, leads to increased overall productivity, an enhanced level of services provided to patients and improved team member satisfaction.

In ensuring the quality of workmanship at construction sites, supervisory skills of site supervisors need to be enhanced. It stressed out that to match business growth and excellence overseas, we must recognize and act on the importance of continuously developing niche expertise and capabilities. Undoubtedly, the role of research in determining the specific leadership skills and the needed core capabilities cannot be over-emphasized. In ensuring the quality of workmanship at construction sites, leadership skills especially supervisory skill for site supervisors need to be enhanced. In this study, quantitative research design with survey questionnaire was used to collect the data and simple random sampling was employed in selecting 248 respondents involving team leaders in construction industry from whole of Malaysia. The data was analyzed using descriptive and inferential statistics; ANOVA in SPSS 21.0. Training and experience in leadership has been found to be significance to leadership capability of team leaders. The opinions from the respondents also indicated that they need the training of leadership and they had to enhance themselves to enable them to become better and more competitive leaders. The results of this assessment can pinpoint the areas needing improvement and therefore can be used as basis in designing and/or deciding development programmes. This study also found that generally the team leaders in construction industry needed more opportunities to expand their leadership capability to become the effective leaders in future.

  17. Drag Performance of Twist Morphing MAV Wing

    Directory of Open Access Journals (Sweden)

    Ismail N.I.


    Full Text Available Morphing wing is one of latest evolution found on MAV wing. However, due to few design problems such as limited MAV wing size and complicated morphing mechanism, the understanding of its aerodynamic behaviour was not fully explored. In fact, the basic drag distribution induced by a morphing MAV wing is still remained unknown. Thus, present work is carried out to compare the drag performance between a twist morphing wing with membrane and rigid MAV wing design. A quasi-static aeroelastic analysis by using the Ansys-Fluid Structure Interaction (FSI method is utilized in current works to predict the drag performance a twist morphing MAV wing design. Based on the drag pattern study, the results exhibits that the morphing wing has a partial similarities in overall drag pattern with the baseline (membrane and rigid wing. However, based CD analysis, it shows that TM wing induced higher CD magnitude (between 25% to 82% higher than to the baseline wing. In fact, TM wing also induced the largest CD increment (about 20% to 27% among the wings. The visualization on vortex structure revealed that TM wing also produce larger tip vortex structure (compared to baseline wings which presume to promote higher induce drag component and subsequently induce its higher CD performance.

  4. Using Transcendental Phenomenology to Explore the “Ripple Effect” in a Leadership Mentoring Program

    Directory of Open Access Journals (Sweden)

    Tammy Moerer-Urdahl


    Full Text Available Several approaches exist for organizing and analyzing data in a phenomenological qualitative study. Transcendental phenomenology, based on principles identified by Husserl (1931 and translated into a qualitative method by Moustakas (1994, holds promise as a viable procedure for phenomenological research. However, to best understand the approach to transcendental phenomenology, the procedures need to be illustrated by a qualitative study that employs this approach. This article first discusses the procedures for organizing and analyzing data according to Moustakas (1994. Then it illustrates each step in the data analysis procedure of transcendental phenomenology using a study of reinvestment or the “ripple effect” for nine individuals who have participated in a youth leadership mentoring program from the 1970s to the present. Transcendental phenomenology works well for this study as this methodology provides logical, systematic, and coherent design elements that lead to an essential description of the experience.

  9. Exploring the use of grounded theory as a methodological approach to examine the 'black box' of network leadership in the national quality forum. (United States)

    Hoflund, A Bryce


    This paper describes how grounded theory was used to investigate the "black box" of network leadership in the creation of the National Quality Forum. Scholars are beginning to recognize the importance of network organizations and are in the embryonic stages of collecting and analyzing data about network leadership processes. Grounded theory, with its focus on deriving theory from empirical data, offers researchers a distinctive way of studying little-known phenomena and is therefore well suited to exploring network leadership processes. Specifically, this paper provides an overview of grounded theory, a discussion of the appropriateness of grounded theory to investigating network phenomena, a description of how the research was conducted, and a discussion of the limitations and lessons learned from using this approach.

  13. Artificial insect wings of diverse morphology for flapping-wing micro air vehicles

    International Nuclear Information System (INIS)

    Shang, J K; Finio, B M; Wood, R J; Combes, S A


    The development of flapping-wing micro air vehicles (MAVs) demands a systematic exploration of the available design space to identify ways in which the unsteady mechanisms governing flapping-wing flight can best be utilized for producing optimal thrust or maneuverability. Mimicking the wing kinematics of biological flight requires examining the potential effects of wing morphology on flight performance, as wings may be specially adapted for flapping flight. For example, insect wings passively deform during flight, leading to instantaneous and potentially unpredictable changes in aerodynamic behavior. Previous studies have postulated various explanations for insect wing complexity, but there lacks a systematic approach for experimentally examining the functional significance of components of wing morphology, and for determining whether or not natural design principles can or should be used for MAVs. In this work, a novel fabrication process to create centimeter-scale wings of great complexity is introduced; via this process, a wing can be fabricated with a large range of desired mechanical and geometric characteristics. We demonstrate the versatility of the process through the creation of planar, insect-like wings with biomimetic venation patterns that approximate the mechanical properties of their natural counterparts under static loads. This process will provide a platform for studies investigating the effects of wing morphology on flight dynamics, which may lead to the design of highly maneuverable and efficient MAVs and insight into the functional morphology of natural wings.

  18. "What you see depends on where you stand" exploring the relationship between leadership behavior and job type in health care. (United States)

    Gover, Laura; Duxbury, Linda


    This chapter seeks to increase our understanding of health care employees' perceptions of effective and ineffective leadership behavior within their organization. Interviews were conducted with 59 employees working in a diversity of positions within the case study hospital. Interviewees were asked to cite behaviors of both an effective and an ineffective leader in their organization. They were also asked to clarify whether their example described the behavior of a formal or informal leader. Grounded theory data analysis techniques were used and findings were interpreting using existing leadership behavior theories. (1) There was a consistent link between effective leadership and relationally oriented behaviors. (2) Employees identified both formal and informal leadership within their hospital. (3) There were both similarities and differences with respect to the types of behaviors attributed to informal versus formal leaders. (4) Informants cited a number of leadership behaviors not yet accounted for in the leadership behavior literature (e.g., 'hands on', 'professional', 'knows organization'). (5) Ineffective leadership behavior is not simply the opposite of effective leadership. Findings support the following ideas: (1) there may be a relationship between the type of job held by employees in health care organizations and their perceptions of leader behavior, and (2) leadership behavior theories are not yet comprehensive enough to account for the varieties of leadership behavior in a health care organization. This study is limited by the fact that it focused on only those leadership theories that considered leader behavior. There are two practical implications for health care organizations. (1) leaders should recognize that the type of behavior an employee prefers from a leader may vary by follower job group (e.g., nurses may prefer relational behavior more than managerial staff do), and (2) organizations could improve leader development programs and evaluation

  19. Perspectives on clinical leadership: a qualitative study exploring the views of senior healthcare leaders in the UK. (United States)

    Nicol, Edward D; Mohanna, Kay; Cowpe, Jenny


    Clinicians are being asked to play a major role leading the NHS. While much is written on about clinical leadership, little research in the medical literature has examined perceptions of the term or mapped the perceived attributes required for success. To capture the views of senior UK healthcare leaders regarding their perception of the term `clinical leadership' and the cultural backdrop in which it is being espoused. UK Healthcare sector PARTICIPANTS: Senior UK Healthcare leaders METHODS: Twenty senior healthcare leaders including a former Health Minister, NHS Executives, NHS Strategic Health Authority, PCT and Acute Trust chief executives and medical directors, Medical Deans and other key actors in the UK medical leadership arena were interviewed between 2010 and 2011 using a semi-structured interview technique. Using grounded theory, themes were identified and subsequently analysed in an attempt to answer the broad questions posed. Not applicable for a qualitative research project RESULTS: A number of themes emerged from this qualitative study. First, there was evidence of changing attitudes among doctors, particularly trainees, towards becoming involved in clinical leadership. However, there was unease over the ambiguity of the term 'clinical leadership' and the implications for the future. There was, however, broad agreement as to the perceived attributes and skills required for success in healthcare leadership. Clinical leadership is often perceived to be doctor centric and 'Healthcare Leadership' may be a more inclusive term. An understanding of the historical medico-political context of the leadership debate is required by all healthcare leaders to fully understand the challenges of changing healthcare culture. Whilst the broad attributes deemed essential for success as a healthcare leaders are not new, significant effort and investment, including a physical Healthcare Academy, are required to best utilise and harmonise the breadth of leadership talent in

  4. Authentic leadership to the future

    Directory of Open Access Journals (Sweden)

    Dimovski Vlado


    Full Text Available Authentic leadership is the latest evolutionary stage in leadership development and emphasizes the leader's authenticity. The construct of authenticity was researched by ancient Greek philosophers as 'know thy-self ', and 'thy true self '. Authentic leadership began to develop after 2004. The main reason why the researchers place so much attention to authentic leadership is fact that authentic leadership reaches all of the employees in organizations. Authentic leaders must identify the strengths of their followers and help them with their development and integration towards a common goal, purpose, vision and identity of the organization. Authentic leadership is seen as the final stage in the development of leadership styles, properties of this leadership style, and the consequences of this style have not been fully explored. In our paper we will explore this new style of leadership and its implications.

  6. Advancing theory development: exploring the leadership-climate relationship as a mechanism of the implementation of cultural competence. (United States)

    Guerrero, Erick G; Fenwick, Karissa; Kong, Yinfei


    Leadership style and specific organizational climates have emerged as critical mechanisms to implement targeted practices in organizations. Drawing from relevant theories, we propose that climate for implementation of cultural competence reflects how transformational leadership may enhance the organizational implementation of culturally responsive practices in health care organizations. Using multilevel data from 427 employees embedded in 112 addiction treatment programs collected in 2013, confirmatory factor analysis showed adequate fit statistics for our measure of climate for implementation of cultural competence (Cronbach's alpha = .88) and three outcomes: knowledge (Cronbach's alpha = .88), services (Cronbach's alpha = .86), and personnel (Cronbach's alpha = .86) practices. Results from multilevel path analyses indicate a positive relationship between employee perceptions of transformational leadership and climate for implementation of cultural competence (standardized indirect effect = .057, bootstrap p climate in the implementation of cultural competence in addiction health service organizations.

    Andrea Jankurová; Ivana Ljudvigová; Klaudia Gubová


    Professional literature on leadership mostly states that a leader should be like (personality traits) and describes different leadership styles and types. However, very little is known about what leaders do in their everyday practice, or how they do it. Leadership should be seen more widely and should be explored along the characteristics and style of leadership and how leaders are manifested externally through their work, which means to explore the nature of leadership work. The aim of the...

  16. Leadership identities

    DEFF Research Database (Denmark)

    Holmgreen, Lise-Lotte


    Questioning the assumption that identities can be controlled through a shared organisational culture, the article explores the inculcation of a discourse of diversity into leadership identities in a Danish bank and building society. Thus, it intends to demonstrate that, on the one hand, discourse...... plays a significant role in identity construction and, on the other, that leaders’ constructions may have many sources of inspiration within and outside the organisation, emphasising that identity construction is a complex process in which organisational efforts to promote a common leadership identity...... compete with shifting subject positions, notions of self and inspirations among leaders. To support this claim, a critical discourse analysis (cf. Fairclough 2003, 2012) is carried out of interviews with two middle managers, which involves close analysis of the language used by the respondents...

Some scholars even set out to know leadership by the identification of traits or behaviors of good leaders. However, the scientific study of leadership requires the identification of a causal theory of leadership. The scientific belief in causation as the common epistemology is the necessary link between the various disciplines interested in leadership (e.g., organizational psychology, statisti...

  1. Leadership development programs for health care middle managers: An exploration of the top management team member perspective. (United States)

    Whaley, Alan; Gillis, William E

    Hospitals throughout the United States establish leadership and management programs for their middle managers. Despite their pervasiveness and an increased emphasis on physician leadership, there is limited research regarding the development programs designed for clinical and nonclinical health care middle managers. Using two theoretical lenses, signaling and institutional theory, this exploratory study investigates mid-sized hospital development programs from the perspective of top management team (TMT) members. Our objective is to find out what types of programs hospitals have, how they are developed, and how they are evaluated. We conducted semistructured interviews with 13 TMT members in six purposefully selected hospitals and matched these interviews with program curricula. Careful coding of the data allowed us not only to show our data in a meaningful visual representation but also to show the progression of the data from raw form to aggregate themes in the qualitative research process. We identified four types of development programs used in the selected hospitals: (a) ongoing series, (b) curriculum-based, (c) management orientation, and (d) mentoring. Challenges existed in aligning the need for the program with program content. Communication occurred both through direct messaging regarding policies and procedures and through hidden signals. TMT members referenced other programs for guidance but were not always clear about what it is they wanted the programs to accomplish. Finally, there was limited program outcome measurement. Our small sample indicates that specific, structured, and comprehensive programs perform best. The better programs were always trying to improve but that most needed better accountability of tracking outcomes. In setting up a program, a collaborative approach among TMT members to establish what the needs are and how to measure outcomes worked well. Successful programs also tied in their leadership development with overall employee

  6. Leadership Training in Otolaryngology Residency. (United States)

    Bent, John P; Fried, Marvin P; Smith, Richard V; Hsueh, Wayne; Choi, Karen


    Although residency training offers numerous leadership opportunities, most residents are not exposed to scripted leadership instruction. To explore one program's attitudes about leadership training, a group of otolaryngology faculty (n = 14) and residents (n = 17) was polled about their attitudes. In terms of self-perception, more faculty (10 of 14, 71.4%) than residents (9 of 17, 52.9%; P = .461) considered themselves good leaders. The majority of faculty and residents (27 of 31) thought that adults could be taught leadership ability. Given attitudes about leadership ability and the potential for improvement through instruction, consideration should be given to including such training in otolaryngology residency.

  13. Anterior foregut microbiota of the glassy-winged sharpshooter explored using deep 16S rRNA gene sequencing from individual insects.

    Directory of Open Access Journals (Sweden)

    Elizabeth E Rogers

    Full Text Available The glassy-winged sharpshooter (GWSS is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidiosa has been shown to colonize the anterior foregut (cibarium and precibarium of sharpshooters, where it may interact with other naturally-occurring bacterial species. To evaluate such interactions, a comprehensive list of bacterial species associated with the sharpshooter cibarium and precibarium is needed. Here, a survey of microbiota associated with the GWSS anterior foregut was conducted. Ninety-six individual GWSS, 24 from each of 4 locations (Bakersfield, CA; Ojai, CA; Quincy, FL; and a laboratory colony, were characterized for bacteria in dissected sharpshooter cibaria and precibaria by amplification and sequencing of a portion of the 16S rRNA gene using Illumina MiSeq technology. An average of approximately 150,000 sequence reads were obtained per insect. The most common genus detected was Wolbachia; sequencing of the Wolbachia ftsZ gene placed this strain in supergroup B, one of two Wolbachia supergroups most commonly associated with arthropods. X. fastidiosa was detected in all 96 individuals examined. By multilocus sequence typing, both X. fastidiosa subspecies fastidiosa and subspecies sandyi were present in GWSS from California and the colony; only subspecies fastidiosa was detected in GWSS from Florida. In addition to Wolbachia and X. fastidiosa, 23 other bacterial genera were detected at or above an average incidence of 0.1%; these included plant-associated microbes (Methylobacterium, Sphingomonas, Agrobacterium, and Ralstonia and soil- or water-associated microbes (Anoxybacillus, Novosphingobium, Caulobacter, and Luteimonas. Sequences belonging to species of the family Enterobacteriaceae also were detected but it was not possible to assign these to individual genera. Many of these species likely interact with X. fastidiosa in the

    Vendrami, Daniel Pagotto; Obara, Marcos Takashi; Gurgel-Gonçalves, Rodrigo; Ceretti-Junior, Walter; Marrelli, Mauro Toledo


    Triatoma sordida has a widespread distribution in Argentina, Bolivia, Brazil, Paraguay, and Uruguay and is frequently found in peridomestic environments. We investigated size and shape variability of T. sordida wings across Brazil. Field-collected adults from twelve populations were studied. For each individual female, seven landmarks on the right wing were digitalized. Shape variables derived from Procrustes superimposition were used in Principal Component Analysis (PCA). Wing size and shape variations among populations was explored by means of ANOVA. Wing centroid size was significantly different among T. sordida populations; specimens from Bahia (East) were larger than those of Mato Grosso do Sul (West). PCA based on wing shape variables showed low wing shape variability. These results reinforce previous data showing low genetic variability among T. sordida populations from Brazil.

    Ling, W; Chia, R C; Fang, L


    In a 1st attempt to identify an implicit theory of leadership among Chinese people, the authors developed the Chinese Implicit Leadership Scale (CILS) in Study 1. In Study 2, they administered the CILS to 622 Chinese participants from 5 occupation groups, to explore differences in perceptions of leadership. Factor analysis yielded 4 factors of leadership: Personal Morality, Goal Efficiency, Interpersonal Competence, and Versatility. Social groups differing in age, gender, education level, and occupation rated these factors. Results showed no significant gender differences, and the underlying cause for social group differences was education level. All groups gave the highest ratings to Interpersonal Competence, reflecting the enormous importance of this factor, which is consistent with Chinese collectivist values.

  7. Improvement of the aerodynamic performance by wing flexibility and elytra–hind wing interaction of a beetle during forward flight (United States)

    Le, Tuyen Quang; Truong, Tien Van; Park, Soo Hyung; Quang Truong, Tri; Ko, Jin Hwan; Park, Hoon Cheol; Byun, Doyoung


    In this work, the aerodynamic performance of beetle wing in free-forward flight was explored by a three-dimensional computational fluid dynamics (CFDs) simulation with measured wing kinematics. It is shown from the CFD results that twist and camber variation, which represent the wing flexibility, are most important when determining the aerodynamic performance. Twisting wing significantly increased the mean lift and camber variation enhanced the mean thrust while the required power was lower than the case when neither was considered. Thus, in a comparison of the power economy among rigid, twisting and flexible models, the flexible model showed the best performance. When the positive effect of wing interaction was added to that of wing flexibility, we found that the elytron created enough lift to support its weight, and the total lift (48.4 mN) generated from the simulation exceeded the gravity force of the beetle (47.5 mN) during forward flight.

  15. The renaissance of clinical leadership. (United States)

    Cook, M J


    The purpose of this work was to explore clinical nursing leadership. The research was based on a critical examination of the leadership themes derived from the nursing literature of the United Kingdom, the United States of America and Australia, between 1992 and 1997. The work was also influenced by the findings from semistructured interviews undertaken with five clinical leaders in nursing from the United Kingdom, and study tours to both the United States of America and Australia. The findings support a proposed leadership model as a basis for further exploration and as a framework for contemplating clinical leadership and leadership preparation. A model is presented that identifies factors which influence leadership styles, such as external environment, internal environment, experience and understanding. Four leadership styles are outlined: transactional, transformational, connective and renaissance. These leadership styles are linked to nursing care approaches. A second model provides a basis for considering power and its impact in the workplace. Based on these findings, the contents of a leadership preparation course are outlined.

  16. Analysing leadership traits in establishing effective leadership at Eskom

    Directory of Open Access Journals (Sweden)

    J. Lekganyane


    Full Text Available Purpose: Leadership is one of the crucial modern topics in the field of management. A leadership trait is one of the three components to be considered in establishing leadership success. The other two components not assessed in this research are ideal leadership behaviour and situational factors. Managers must act as leaders as they have a critical role to play to ensure effective change. This paper explores the leadership traits relevant to middle managers acting as leaders at Eskom. Design/Methodology/Approach: A theoretical analysis of literature in the field of leadership is conducted with a further focus on leadership traits. Quantitative research is done within Eskom by means of an e-mail survey to a random sample of employees on middle management level. Areas of possible improvement and leadership traits excellence are identified. Recommendations are made regarding leadership traits. Findings: The broad leadership trait categories tested include: intelligence; flexibility; sensitivity to others; stability; dominance; high energy; integrity (honesty and ethics; and finally locus of control. The most dominant traits based on the perception of the respondents are that they possess integrity, intelligence, high energy and the ability to act as leaders. Leadership traits that require great attention and are not as dominant are sensitivity to others, flexibility and to some extent stability. Implications: Managers must have the leadership ability and trait to influence employees in order to communicate, direct, negotiate and motivate with success. Teamwork and a relationship of trust are required in the modern and changing organisation in order to be successful in achieving organisational goals. Originality / Value: South Africa as well as Southern Africa could face an energy crisis in the near future. As Eskom is currently facing growing demand for services and is experiencing limitations to provide this continuous increase in demand, managers

  1. Exploration

    International Nuclear Information System (INIS)

    Lohrenz, J.


    Oil and gas exploration is a unique kind of business. Businesses providing a vast and ever-changing panoply of products to markets are a focus of several disciplines' energetic study and analysis. The product inventory problem is robust, pertinent, and meaningful, and it merits the voluminous and protracted attention received from keen business practitioners. Prototypical business practitioners, be they trained by years of business hurly-burly, or sophisticated MBAs with arrays of mathematical algorithms and computers, are not normally prepared, however, to recognize the unique nature of exploration's inventories. Put together such a business practitioner with an explorationist and misunderstandings, hidden and open, are inevitable and predictably rife. The first purpose of this paper is to articulate the inherited inventory handling paradigms of business practitioners in relation to exploration's inventories. To do so, standard pedagogy in business administration is used and a case study of an exploration venture is presented. A second purpose is to show the burdens that the misunderstandings create. The result is not just business plans that go awry, but public policies that have effects opposite from those intended

  2. Folding wings like a cockroach: a review of transverse wing folding ensign wasps (Hymenoptera: Evaniidae: Afrevania and Trissevania.

    Directory of Open Access Journals (Sweden)

    István Mikó

    Full Text Available We revise two relatively rare ensign wasp genera, whose species are restricted to Sub-Saharan Africa: Afrevania and Trissevania. Afrevania longipetiolata sp. nov., Trissevania heatherae sp. nov., T. hugoi sp. nov., T. mrimaensis sp. nov. and T. slideri sp. nov. are described, males and females of T. anemotis and Afrevania leroyi are redescribed, and an identification key for Trissevaniini is provided. We argue that Trissevania mrimaensis sp. nov. and T. heatherae sp. nov. populations are vulnerable, given their limited distributions and threats from mining activities in Kenya. We hypothesize that these taxa together comprise a monophyletic lineage, Trissevaniini, tr. nov., the members of which share the ability to fold their fore wings along two intersecting fold lines. Although wing folding of this type has been described for the hind wing of some insects four-plane wing folding of the fore wing has never been documented. The wing folding mechanism and the pattern of wing folds of Trissevaniini is shared only with some cockroach species (Blattodea. It is an interesting coincidence that all evaniids are predators of cockroach eggs. The major wing fold lines of Trissevaniini likely are not homologous to any known longitudinal anatomical structures on the wings of other Evaniidae. Members of the new tribe share the presence of a coupling mechanism between the fore wing and the mesosoma that is composed of a setal patch on the mesosoma and the retinaculum of the fore wing. While the setal patch is an evolutionary novelty, the retinaculum, which originally evolved to facilitate fore and hind wing coupling in Hymenoptera, exemplifies morphological exaptation. We also refine and clarify the Semantic Phenotype approach used in previous taxonomic revisions and explore the consequences of merging new with existing data. The way that semantic statements are formulated can evolve in parallel, alongside improvements to the ontologies themselves.

  14. Learning Leadership

    DEFF Research Database (Denmark)

    Hertel, Frederik; Fast, Alf Michael


    Is leadership a result of inheritance or is it something one learns during formal learning in e.g. business schools? This is the essential question addressed in this article. The article is based on a case study involving a new leader in charge of a group of profession practitioners. The leader...... promotes his leadership as a profession comparable to the professions of practitioners. This promotion implies that leadership is something one can and probably must learn during formal learning. The practitioners on the other hand reject this comprehension of leadership and long for a fellow practitioner...... to lead the organization. While asked they are unable to describe how, where and when they think a practitioner develops leadership skills necessary for leading fellows. In the following we will start analysing the case in order to comprehend and discuss both the professional leaders and the practitioners...

    Full Text Available Exploring the state of Nigerian leadership, there is a clear indication that the nation is in distress and therefore needs a leader who would be able to get the best out of Nigerian followers and lead the nation to stability. This leader must be trustworthy, emotionally intelligent, firm, willing to suffer for the nation, focused on breaking down ethnic divide, and inspiring hope in the people. The leader must be capable of taking in varied information and solving complex problems effectively and efficiently. This paper adopts the concept of leadership as one that involves a social influence process, a leader/leaders and followers. This perspective is impacted by social psychological principles of social influence and clinical psychology socioemotional intelligence and will therefore discuss leadership for Nigeria from these perspectives.

  18. Leadership mindset in mental health. (United States)

    Ng, Lillian; Steane, Richard; Scollay, Natalie


    The objective of this study was to explore the concept of mindset for psychiatrists who are considering stepping into the leadership arena. Qualitative themes were extracted from dialogue on leadership development at a Royal Australian and New Zealand College of Psychiatrists forum for early career psychiatrists. Three key themes were identified: adapting to a professional identity as psychiatrists; developing a mindset for leadership; and acting intentionally to seek opportunities for leadership. Shifts in professional identity occur in the transition from trainee to specialist as early career psychiatrists become increasingly aware of broad systemic factors in clinical care. The concept of a mindset, distinct from a skillset of knowledge and expertise, may be an emergent quality for psychiatrists who are seeking to develop their leadership potential.

  2. Transformational leadership in nursing: a concept analysis. (United States)

    Fischer, Shelly A


    To analyse the concept of transformational leadership in the nursing context. Tasked with improving patient outcomes while decreasing the cost of care provision, nurses need strategies for implementing reform in health care and one promising strategy is transformational leadership. Exploration and greater understanding of transformational leadership and the potential it holds is integral to performance improvement and patient safety. Concept analysis using Walker and Avant's (2005) concept analysis method. PubMed, CINAHL and PsychINFO. This report draws on extant literature on transformational leadership, management, and nursing to effectively analyze the concept of transformational leadership in the nursing context. This report proposes a new operational definition for transformational leadership and identifies model cases and defining attributes that are specific to the nursing context. The influence of transformational leadership on organizational culture and patient outcomes is evident. Of particular interest is the finding that transformational leadership can be defined as a set of teachable competencies. However, the mechanism by which transformational leadership influences patient outcomes remains unclear. Transformational leadership in nursing has been associated with high-performing teams and improved patient care, but rarely has it been considered as a set of competencies that can be taught. Also, further research is warranted to strengthen empirical referents; this can be done by improving the operational definition, reducing ambiguity in key constructs and exploring the specific mechanisms by which transformational leadership influences healthcare outcomes to validate subscale measures. © 2016 John Wiley & Sons Ltd.

  9. Aerodynamic characteristics and flow field of delta wings with the canard

    Directory of Open Access Journals (Sweden)

    Mochizuki Saya


    Full Text Available Now, many kinds of explorations for outer planets have been proposed around the world. Among them Mars attracts much attention for future exploration. Orbiters and landers have been used for Mars exploration. Recently as a new exploration method, the usage of an airplane has been seriously considered and there are some development projects for Mars airplane. However, the airplane flying on the Earth atmosphere cannot fly on the Mars atmosphere, because atmospheric conditions are much different each other. Therefore, we focused on the usage of the airplane with unfolding wings for Mars exploration. These unfolding wings are designed as delta wings. However, delta wings do not have enough aerodynamics characteristics in a low speed region. In this study, to improve the aerodynamic characteristics of delta wings, we have proposed the usage of canard wings. The purpose of this study is to examine the effectiveness of canard wings to improve aerodynamic characteristics in a low speed region. CFD analysis is performed using four wing models with different canard shapes. The result shows that the usage of canards is effective to improve aerodynamic characteristics of delta wings in a low speed region. In addition, increasing lift coefficient is possible by changing the shape of canards.

  12. Research of the Nature of Leadership Activities

    Directory of Open Access Journals (Sweden)

    Andrea Jankurová


    Full Text Available Professional literature on leadership mostly states that a leader should be like (personality traits and describes different leadership styles and types. However, very little is known about what leaders do in their everyday practice, or how they do it. Leadership should be seen more widely and should be explored along the characteristics and style of leadership and how leaders are manifested externally through their work, which means to explore the nature of leadership work. The aim of the research project was to gain more knowledge about the activities undertaken by leaders to answer a simple, but yet not too clearly answered question: „What does a leader really do?“ This finding will help reveal important activities on which best leaders focus and determine which elements are really important for leadership. The research project was managed as a combination of interviews conducted with leaders, people on senior management positions along with a questionnaire survey.

  14. Wing shape allometry and aerodynamics in calopterygid damselflies: a comparative approach. (United States)

    Outomuro, David; Adams, Dean C; Johansson, Frank


    Wing size and shape have important aerodynamic implications on flight performance. We explored how wing size was related to wing shape in territorial males of 37 taxa of the damselfly family Calopterygidae. Wing coloration was also included in the analyses because it is sexually and naturally selected and has been shown to be related to wing shape. We studied wing shape using both the non-dimensional radius of the second moment of wing area (RSM) and geometric morphometrics. Lower values of the RSM result in less energetically demanding flight and wider ranges of flight speed. We also re-analyzed previously published data on other damselflies and dragonflies. The RSM showed a hump-shaped relationship with wing size. However, after correcting for phylogeny using independent contrast, this pattern changed to a negative linear relationship. The basal genus of the study family, Hetaerina, was mainly driving that change. The obtained patterns were specific for the study family and differed from other damselflies and dragonflies. The relationship between the RSM and wing shape measured by geometric morphometrics was linear, but relatively small changes along the RSM axis can result in large changes in wing shape. Our results also showed that wing coloration may have some effect on RSM. We found that RSM showed a complex relationship with size in calopterygid damselflies, probably as a result of other selection pressures besides wing size per se. Wing coloration and specific behavior (e.g. courtship) are potential candidates for explaining the complexity. Univariate measures of wing shape such as RSM are more intuitive but lack the high resolution of other multivariate techniques such as geometric morphometrics. We suggest that the relationship between wing shape and size are taxa-specific and differ among closely-related insect groups.

  15. Design optimization of deployable wings (United States)

    Gaddam, Pradeep

    Morphing technology is an important aspect of UAV design, particularly in regards to deployable systems. The design of such system has an important impact on the vehicle's performance. The primary focus of the present research work was to determine the most optimum deployable wing design from 3 competing designs and develop one of the deployable wing designs to test in the research facility. A Matlab code was developed to optimize 3 deployable wing concepts inflatable, inflatable telescopic and rigid-folding wings based on a sequential optimization strategy. The constraints that were part of the code include the packaging constraints during its stowed state, fixed length of the deployed section and the minimum L/D constraint. This code resulted in determining the optimum weight of all the 3 designs, the most optimum weight design is the inflatable wing design. This is a result of the flexible skin material and also due to no rigid parts in the deployed wing section. Another goal of the research involved developing an inflatable telescopic wing. The prototype was tested in a wind tunnel, while the actual wing was tested in the altitude chamber to determine the deployment speed, input pressure, analyze and predict the deployment sequence and behavior of the wing at such high wind speeds and altitudes ranging from 60,000 ft to 90,000 ft. Results from these tests allowed us to conclude the deployment sequence of the telescopic wing followed from the root to the tip section. The results were used to analyze the deployment time of the wing. As expected the deployment time decreased with an increase in input pressure. The results also show us that as the altitude increases, the deployment speed of the wing also increased. This was demonstrated when the wing was tested at a maximum altitude pressure of 90,000ft, well above the design altitude of 60,000ft.

  17. Transformational leadership behaviors in allied health professions. (United States)

    Wylie, David A; Gallagher, Helen L


    The aim of this study was to explore self-reported transformational leadership behavior profiles within the six largest allied health profession groups in the National Health Service in Scotland and to determine whether factors such as seniority of grade, locus of employment, and/or leadership training have a positive influence on transformational leadership behaviors. A postal survey comprising the shorter version of the Multifactorial Leadership Questionnaire (MLQ) and contextual demographic information was completed by 753 allied health professionals from four Health Board areas across Scotland who were randomly selected through a modified cluster sampling technique. The MLQ contains 36 items that measure nine identified leadership factors; however, only the responses to the five transformational leadership factors are reported here. The study identified significant differences in transformational leadership behaviors between individual allied health professions. Radiographers and podiatrists scored consistently lower than the other professional groups across the range of transformational behaviors. Seniority of grade significantly influenced the scores, with higher-graded staff reporting greater leadership behaviors (p leadership training also positively influenced transformational behaviors (p transformational leadership behaviors between individual allied health professions, indicating that some professional groups are inherently advantaged in embracing the modernization agenda. This highlights an as-yet missed opportunity for effectively targeting and evaluating multidisciplinary leadership training programs across the allied health professions.

  19. 7 transformations of leadership. (United States)

    Rooke, David; Torbert, William R


    Most developmental psychologists agree that what differentiates one leader from another is not so much philosophy of leadership, personality, or style of management. Rather, it's internal "action logic"--how a leader interprets the surroundings and reacts when his or her power or safety is challenged. Relatively few leaders, however, try to understand their action logic, and fewer still have explored the possibility of changing it. They should, because leaders who undertake this voyage of personal understanding and development can transform not only their own capabilities but also those of their companies. The authors draw on 25 years of consulting experience and collaboration with psychologist Susanne Cook-Greuter to present a typology of leadership based on the way managers personally make sense of the world around them. Rooke and Torbert classify leaders into seven distinct actionlogic categories: Opportunists, Diplomats, Experts, Achievers, Individualists, Strategists, and Alchemists-the first three associated with below-average performance, the latter four with medium to high performance. These leadership styles are not fixed, the authors say, and executives who are willing to work at developing themselves and becoming more self-aware can almost certainly move toward one of the more effective action logics. A Diplomat, for instance, can succeed through hard work and self-reflection at transforming himself into a Strategist. Few people may become Alchemists, but many will have the desire and potential to become Individualists and Strategists. Corporations that help their executives and leadership teams to examine their action logics can reap rich rewards.

  20. Teacher leadership and educational innovation

    Directory of Open Access Journals (Sweden)

    Frost David


    Full Text Available This national conference was arranged by the Ministry of Education to support the drive to modernize the education system as a whole. This paper is based on David Frost’s presentation which explored the links between a transformative view of education, the nature of innovation and the need to develop teacher leadership. It is argued that, in transformative education, learning centres on the cultivation of capacities and dispositions. These are exemplified and illustrated. Key concepts such as agency, meta-learning, self-regulation and their link to citizenship are explained. The distinction is drawn between implementation and innovation as a process which is both long and arduous. It is argued that such a process of innovation demands learning at all levels (students, teachers, the school, the system, but teacher leadership is where the most potential lies. Stories of teacher leadership are used to illustrate what can be achieved and claims are made as to the benefits of teacher leadership. It is claimed that teacher leadership can mobilise teachers’ capacity for leading change, improve quality in the system and build professional knowledge that teachers trust. The paper concludes by outlining the theory of teacher leadership promoted by the International Teacher Leadership project.

  1. Transformational leadership. (United States)

    Taccetta-Chapnick, M


    Rapid changes in the health care system have caused competition among institutions, as organizations are restructured to increase client satisfaction, resulting in the need for a new style of leadership. The transformational leader communicates the mission and vision of the organization and empowers others to effectively resolve conflicts that may arise with change. The health care team that can cope with changes and conflicts views restructuring as a positive transaction and approaches client satisfaction with energy and motivation. Institutions with transformational leadership are the ones that will survive the transition.

  3. Leadership and leadership development within the profession of physiotherapy in Ireland. (United States)

    McGowan, Emer; Stokes, Emma


    Health service reform, physiotherapy graduate unemployment, and the impending introduction of state regulation mean that physiotherapists in Ireland today are facing many challenges. Leadership is needed to ensure that the profession will be able to adapt to the demands and inevitable changes ahead. To investigate the perceptions of physiotherapists in Ireland of leadership and leadership characteristics, and to explore their participation in leadership development training. In this cross-sectional nationwide study, an Internet-based survey was administered via e-mail to members of the Irish Society of Chartered Physiotherapists (n = 2,787). There were 615 responses to the survey. A high proportion of respondents (74.0%) perceived themselves to be a leader. Factors associated with self-declaration as a leader were time since graduation, highest qualification attained, and leadership training. Leadership training was also associated with placing greater importance on achieving a leadership position. Some form of leadership training had been completed by 41.5% of respondents. Communication and professionalism were the most highly rated leadership characteristics in all three settings. Physiotherapists who have had leadership training were more likely to perceive themselves to be leaders. Leadership training may support physiotherapists to assume leadership roles both clinically and nonclinically.

  13. Leadership wisdom. (United States)

    Melanson, Mark A


    Becoming a good leader starts with effectively leading yourself. Good leadership flows from good followership. While leaders need to be adaptive, they need to make sure that change is actually necessary and not merely the illusion of progress. Effective juggling of leadership responsibilities requires identifying the glass balls and making sure that they do not drop. Leaders need to be visible and be out front, especially when things get rough or when they are the most perilous. Anger should never be allowed to reign and cloud a leader's judgment. Leadership is not "one size fits all," those being led are unique and, consequently, different approaches will be necessary to properly motivate followers. When considering important leadership decisions, it is advisable to seek out your own Napoleon's Corporal to be sure that your plan is sound and those who will implement it do in fact fully understand it. Genuine belief in your Soldiers is the most powerful and lasting thing that you can express as a leader. Lastly, mentoring is a solemn responsibility of leaders that must never be eclipsed by the many literal and figurative battles of the day.

  4. The impact of nurse managers' leadership styles on ward staff. (United States)

    Saleh, Usama; O'Connor, Tom; Al-Subhi, Hattan; Alkattan, Rana; Al-Harbi, Saad; Patton, Declan


    to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside. leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them. the study employed qualitative methodology, involving 35 nurses working in different specialties of a medical city in Saudi Arabia. Data collection consisted of completing demographic and professional information and a semi-structured interview using open-ended questions. a phenomenologic-hermeneutic approach was used to identify major themes. the findings showed that participants described four types of leadership styles: relational leadership, preferential leadership, communication chain leadership, and ineffectual leadership. the leadership style employed by nurse managers has a major impact on nurses' satisfaction, turnover, and the quality of patient care they deliver.

  5. Ornithopter Type Flapping Wings for Autonomous Micro Air Vehicles

    Full Text Available In this paper, an ornithopter prototype that mimics the flapping motion of bird flight is developed, and the lift and thrust generation characteristics of different wing designs are evaluated. This project focused on the spar arrangement and material used for the wings that could achieves improved performance. Various lift and thrust measurement techniques are explored and evaluated. Various wings of insects and birds were evaluated to understand how these natural flyers with flapping wings are able to produce sufficient lift to fly. The differences in the flapping aerodynamics were also detailed. Experiments on different wing designs and materials were conducted and a paramount wing was built for a test flight. The first prototype has a length of 46.5 cm, wing span of 88 cm, and weighs 161 g. A mechanism which produced a flapping motion was fabricated and designed to create flapping flight. The flapping flight was produced by using a single motor and a flexible and light wing structure. A force balance made of load cell was then designed to measure the thrust and lift force of the ornithopter. Three sets of wings varying flexibility were fabricated, therefore lift and thrust measurements were acquired from each different set of wings. The lift will be measured in ten cycles computing the average lift and frequency in three different speeds or frequencies (slow, medium and fast. The thrust measurement was measure likewise but in two cycles only. Several observations were made regarding the behavior of flexible flapping wings that should aid in the design of future flexible flapping wing vehicles. The wings angle or phase characteristic were analyze too and studied. The final ornithopter prototype weighs only 160 g, has a wing span of 88.5 cm, that could flap at a maximum flapping frequency of 3.869 Hz, and produce a maximum thrust and lift of about 0.719 and 0.264 N respectively. Next, we proposed resonance type flapping wing utilizes the near

  6. Clinical leadership project. (United States)

    Kling, Vera G


    Nurse educators seek innovative strategies to maximize student learning in the classroom and clinical settings. Students enrolled in a nursing leadership and management course often find they spend more clinical time observing leaders than practicing the necessary skills to lead others in the provision of nursing care. In addition, opportunities to explore the nurse educator role often do not exist in baccalaureate nursing education, despite the shortage of nurse educators. An experience was developed in a baccalaureate nursing program to give senior students, under supervision of faculty, the opportunity to lead and evaluate lower-level students providing patient care in the clinical setting and to experience the role of nursing faculty. Feedback from senior students was positive, and students noted increased proficiency in leadership ability and critical thinking. Student interest in the nurse educator role was also enhanced. Program expansion and evaluation with faculty, clinical staff, and patients are planned. Copyright 2010, SLACK Incorporated.

  11. Aeroelastic Wing Shaping Using Distributed Propulsion (United States)

    Nguyen, Nhan T. (Inventor); Reynolds, Kevin Wayne (Inventor); Ting, Eric B. (Inventor)


    An aircraft has wings configured to twist during flight. Inboard and outboard propulsion devices, such as turbofans or other propulsors, are connected to each wing, and are spaced along the wing span. A flight controller independently controls thrust of the inboard and outboard propulsion devices to significantly change flight dynamics, including changing thrust of outboard propulsion devices to twist the wing, and to differentially apply thrust on each wing to change yaw and other aspects of the aircraft during various stages of a flight mission. One or more generators can be positioned upon the wing to provide power for propulsion devices on the same wing, and on an opposite wing.

  12. Butterflies regulate wing temperatures using radiative cooling (United States)

    Tsai, Cheng-Chia; Shi, Norman Nan; Ren, Crystal; Pelaez, Julianne; Bernard, Gary D.; Yu, Nanfang; Pierce, Naomi


    Butterfly wings are live organs embedded with multiple sensory neurons and, in some species, with pheromoneproducing cells. The proper function of butterfly wings demands a suitable temperature range, but the wings can overheat quickly in the sun due to their small thermal capacity. We developed an infrared technique to map butterfly wing temperatures and discovered that despite the wings' diverse visible colors, regions of wings that contain live cells are the coolest, resulting from the thickness of the wings and scale nanostructures. We also demonstrated that butterflies use behavioral traits to prevent overheating of their wings.

  15. Stiffness of desiccating insect wings

    Energy Technology Data Exchange (ETDEWEB)

    Mengesha, T E; Vallance, R R [Department of Mechanical Engineering, The George Washington University, 738 Phillips Hall, 801 22nd St NW, Washington, DC 20052 (United States); Mittal, R, E-mail: [Department of Mechanical Engineering, Johns Hopkins University, 126 Latrobe Hall, 3400 N Charles Street, Baltimore, MD 21218 (United States)


    The stiffness of insect wings is typically determined through experimental measurements. Such experiments are performed on wings removed from insects. However, the wings are subject to desiccation which typically leads to an increase in their stiffness. Although this effect of desiccation is well known, a comprehensive study of the rate of change in stiffness of desiccating insect wings would be a significant aid in planning experiments as well as interpreting data from such experiments. This communication presents a comprehensive experimental analysis of the change in mass and stiffness of gradually desiccating forewings of Painted Lady butterflies (Vanessa cardui). Mass and stiffness of the forewings of five butterflies were simultaneously measured every 10 min over a 24 h period. The averaged results show that wing mass declined exponentially by 21.1% over this time period with a time constant of 9.8 h, while wing stiffness increased linearly by 46.2% at a rate of 23.4 {mu}N mm{sup -1} h{sup -1}. For the forewings of a single butterfly, the experiment was performed over a period of 1 week, and the results show that wing mass declined exponentially by 52.2% with a time constant of 30.2 h until it reached a steady-state level of 2.00 mg, while wing stiffness increased exponentially by 90.7% until it reached a steady-state level of 1.70 mN mm{sup -1}.

    Full Text Available Observers have always been fascinated by soaring birds. An interesting feature of these birds is the existence of few feathers extending from the tip of the wing. In this paper, small lifting surfaces were fitted to the tip of a NACA0012 wing in a fashion similar to that of wing tip feathers. Experimental measurements of induced drag, longitudinal static stability and trailing vortex structure were obtained.The tests showed that adding wing tip surfaces (sails decreased the induced drag factor and increased the longitudinal static stability. Results identified two discrete appositely rotated tip vortices and showed the ability of wing tip surfaces to break them down and to diffuse them.

  2. Shared leadership and group identification in healthcare: The leadership beliefs of clinicians working in interprofessional teams. (United States)

    Forsyth, Craig; Mason, Barbara


    Despite the proposed benefits of applying shared and distributed leadership models in healthcare, few studies have explored the leadership beliefs of clinicians and ascertained whether differences exist between professions. The current article aims to address these gaps and, additionally, examine whether clinicians' leadership beliefs are associated with the strength of their professional and team identifications. An online survey was responded to by 229 healthcare workers from community interprofessional teams in mental health settings across the East of England. No differences emerged between professional groups in their leadership beliefs; all professions reported a high level of agreement with shared leadership. A positive association emerged between professional identification and shared leadership in that participants who expressed the strongest level of profession identification also reported the greatest agreement with shared leadership. The same association was demonstrated for team identification and shared leadership. The findings highlight the important link between group identification and leadership beliefs, suggesting that strategies that promote strong professional and team identifications in interprofessional teams are likely to be conducive to clinicians supporting principles of shared leadership. Future research is needed to strengthen this link and examine the leadership practices of healthcare workers.

    Itri, Jason N; Lawson, Leslie M


    Radiology leaders can have a profound impact on the success and working environment of a radiology department, promoting core values and inspiring staff members to achieve the organization's mission. On the other hand, ineffective leaders can have a devastating effect on a radiology department by impairing communication among members, undermining staff commitment to the organization's success, and stifling the development of other staff members and leaders in the organization. One of the most important investments a radiology department can make is in identifying, cultivating, and promoting new leaders. The authors describe 13 habits and characteristics of new leaders that lead these individuals to address situations in both ineffective and counterproductive ways, impeding the performance of a radiology department and its capacity to play a meaningful role in shaping the future of radiology. New leaders must continually learn and improve their leadership skills if they are to avoid the destructive habits of ineffective leaders and successfully overcome the challenges facing radiology today. Senior leaders may also benefit from understanding the pitfalls that make leaders ineffective and should strive to continually improve their leadership skills given the critical role of leadership in the success of radiology departments.

  9. United States Human Access to Space, Exploration of the Moon and Preparation for Mars Exploration (United States)

    Rhatigan, Jennifer L.


    In the past, men like Leonardo da Vinci and Jules Verne imagined the future and envisioned fantastic inventions such as winged flying machines, submarines, and parachutes, and posited human adventures like transoceanic flight and journeys to the Moon. Today, many of their ideas are reality and form the basis for our modern world. While individual visionaries like da Vinci and Verne are remembered for the accuracy of their predictions, today entire nations are involved in the process of envisioning and defining the future development of mankind, both on and beyond the Earth itself. Recently, Russian, European, and Chinese teams have all announced plans for developing their own next generation human space vehicles. The Chinese have announced their intention to conduct human lunar exploration, and have flown three crewed space missions since 2003, including a flight with three crew members to test their extravehicular (spacewalking) capabilities in September 2008. Very soon, the prestige, economic development, scientific discovery, and strategic security advantage historically associated with leadership in space exploration and exploitation may no longer be the undisputed province of the United States. Much like the sponsors of the seafaring explorers of da Vinci's age, we are motivated by the opportunity to obtain new knowledge and new resources for the growth and development of our own civilization. NASA's new Constellation Program, established in 2005, is tasked with maintaining the United States leadership in space, exploring the Moon, creating a sustained human lunar presence, and eventually extending human operations to Mars and beyond. Through 2008, the Constellation Program developed a full set of detailed program requirements and is now completing the preliminary design phase for the new Orion Crew Exploration Vehicle (CEV), the Ares I Crew Launch Vehicle, and the associated infrastructure necessary for humans to explore the Moon.

  16. Relationship Between Leadership Styles and Organizational Creativity

    Directory of Open Access Journals (Sweden)

    Katarzyna Bratnicka


    Full Text Available Purpose: Empirical research on entrepreneurship in organizations has brought disparate and often contradictory evidence related to the impact of leadership on creativity in organizations. The purpose of this paper is to explore and discuss the impact of different leadership styles on creativity, with the view to formulating an integrated conceptual model that links creative novelty and creative practicality with leadership. Methodology: The author applied the methodology of meta-theoretical review. In accordance with the principles of theoretical bricolage, a new conceptual model was built on the basis of the multidimensional creativity theory and the leadership theory. In her analysis, the author took into account leadership styles that have already been subject to research; each of them was mapped in the two-dimensional space of organizational creativity. Findings: In order to fully understand the reasons for differences in organizational creativity, the drivers of divergences in the space of creative novelty and creative practicality need to be clarified. Greater knowledge about the impact of leadership styles on the structure and configuration of organizational creativity is necessary. In this paper, the author provides a theoretical framework that illustrates manners in which leadership influences organizational creativity. The model clarifies the role that leadership plays in shaping a unique configuration of organizational creativity, and consequently in ensuring the necessary internal adaptation of an organization. Originality: The value of this research lies in the situational interpretation of various leadership styles in the context of their impact on organizational creativity. The analysis goes beyond the conventional discussion about leadership and creativity, focused on establishing whether a given leadership style proves beneficial or not for organizational creativity. The paper identifies particular effects that several key

  17. Leadership style and patient safety: implications for nurse managers. (United States)

    Merrill, Katreena Collette


    The purpose of this study was to explore the relationship between nurse manager (NM) leadership style and safety climate. Nursing leaders are needed who will change the environment and increase patient safety. Hospital NMs are positioned to impact day-to-day operations. Therefore, it is essential to inform nurse executives regarding the impact of leadership style on patient safety. A descriptive correlational study was conducted in 41 nursing departments across 9 hospitals. The hospital unit safety climate survey and multifactorial leadership questionnaire were completed by 466 staff nurses. Bivariate and regression analyses were conducted to determine how well leadership style predicted safety climate. Transformational leadership style was demonstrated as a positive contributor to safety climate, whereas laissez-faire leadership style was shown to negatively contribute to unit socialization and a culture of blame. Nursing leaders must concentrate on developing transformational leadership skills while also diminishing negative leadership styles.

  18. The Impact of Entrepreneurial Leadership on Nurses' Innovation Behavior. (United States)

    Bagheri, Afsaneh; Akbari, Morteza


    The purpose of this study was to examine the influence of entrepreneurial leadership on nurses' innovation work behavior and its dimensions. This cross-sectional study employed the 10-item Innovation Work Behavior Questionnaire and the 8-item Entrepreneurial Leadership Questionnaire to explore the impact of entrepreneurial leadership on the innovation work behavior of 273 nurses from public and private hospitals in Iran. Entrepreneurial leadership had a significant positive impact on nurses' innovation work behavior and most strongly improved idea exploration, followed by idea generation, idea implementation, and idea championing. Entrepreneurial leadership was effective in enhancing nurses' innovation work behavior. More attention needs to be focused on developing entrepreneurial leadership competencies and on developing nurse leaders. Healthcare policies and strategies are needed to facilitate the implementation of entrepreneurial leadership by providing healthcare leaders with the appropriate environment. © 2017 Sigma Theta Tau International.

  19. Role of nursing leadership in providing compassionate care. (United States)

    Quinn, Barry


    This article encourages nurses to explore the concept of leadership in the constantly changing field of health and social care. All nurses have an important role in leadership, and they should consider what type of leader they want to be and what leadership skills they might wish to develop. This article examines what leadership might involve, exploring various leadership styles and characteristics and how these could be applied in nurses' practice. A core component of nursing and nursing leadership is the ability to provide compassionate care. This could correspond with the idea of servant leadership, an approach that moves the leader from a position of power to serving the team and supporting individuals to develop their potential. ©2017 RCN Publishing Company Ltd.

  20. Leadership styles in nursing management: preferred and perceived. (United States)

    Sellgren, Stina; Ekvall, Göran; Tomson, Göran


    The aim was to explore nursing leadership regarding what nurse managers and subordinates see as important and to explore subordinates' opinions of their nurse manager's performance in reality. Background The manager's style can be fundamental for subordinates' acceptance of change and in motivating them to achieve stated visions and goals and high quality of care. Nurse managers (n=77) and 10 of each included nurse manager's subordinates received a questionnaire to assess 'preferred' leadership behaviour in three dimensions: change, production and employee/relation orientations. The same questionnaire was used to assess subordinates' opinions of their manager's leadership behaviour. There are statistically significant differences in opinions of preferred leadership between managers and subordinates, especially related to production and relation orientation. The subordinates' perception of real leadership behaviour has lower mean values than their preferred leadership behaviour in all three dimensions. Subordinates prefer managers with more clearly expressed leadership behaviour than managers themselves prefer and demonstrate.

  3. Wings versus legs in the avian bauplan: development and evolution of alternative locomotor strategies. (United States)

    Heers, Ashley M; Dial, Kenneth P


    Wings have long been regarded as a hallmark of evolutionary innovation, allowing insects, birds, and bats to radiate into aerial environments. For many groups, our intuitive and colloquial perspective is that wings function for aerial activities, and legs for terrestrial, in a relatively independent manner. However, insects and birds often engage their wings and legs cooperatively. In addition, the degree of autonomy between wings and legs may be constrained by tradeoffs, between allocating resources to wings versus legs during development, or between wing versus leg investment and performance (because legs must be carried as baggage by wings during flight and vice versa). Such tradeoffs would profoundly affect the development and evolution of locomotor strategies, and many related aspects of animal ecology. Here, we provide the first evaluation of wing versus leg investment, performance and relative use, in birds-both across species, and during ontogeny in three precocial species with different ecologies. Our results suggest that tradeoffs between wing and leg modules help shape ontogenetic and evolutionary trajectories, but can be offset by recruiting modules cooperatively. These findings offer a new paradigm for exploring locomotor strategies of flying organisms and their extinct precursors, and thereby elucidating some of the most spectacular diversity in animal history. © 2014 The Author(s).

  4. Extensive Rangewide Mitochondrial Introgression Indicates Substantial Cryptic Hybridization in the Golden-winged Warbler (Vermivora chrysoptera

    Directory of Open Access Journals (Sweden)

    Rachel Vallender


    Full Text Available Widespread population declines of the Golden-winged Warbler (Vermivora chrysoptera are thought to be due in part to hybridization with the expanding Blue-winged Warbler (V. pinus, which predictably replaces Golden-winged Warblers at breeding sites in which the two species come into contact. However, the mechanism by which this replacement occurs remains unresolved. Recent genetic work has indicated that, even in areas where the two species have been in contact for a short period, introgression of Blue-winged mitochondrial (mtDNA and nuclear genes into Golden-winged individuals is common. To explore this process on a broader scale, we screened more than 750 individuals from nine U.S. states and three provinces to examine geographic patterns of mtDNA introgression. The only population in which all phenotypic Golden-winged Warblers had Golden-winged mtDNA haplotypes, and in which there are no breeding Blue-winged or hybrid individuals, was in the province of Manitoba, near the northwestern edge of the species' breeding distribution. The near ubiquity of mitochondrial introgression suggests that there are far fewer genetically pure populations of Golden-winged Warblers than previously believed, a finding with important implications for this threatened species.

  7. Transforming Leadership Styles and Knowledge Sharing in a Multicultural Context

    Directory of Open Access Journals (Sweden)

    Rasa Paulienė


    Full Text Available Despite limitations on comprehensive studies, scholars accept that transformational and transactional leadership theories will have a universal application because these models have capacity for being adapted to different cultural settings. However, more exploration is required in order to develop a strong and consistent picture of the generalizability of culturally-linked leadership styles differently perceived, evaluated or enacted in diverse cultures because the meaning and importance given to the concept of leadership vary across cultures. By comparing and contrasting the number of cultural frameworks of leadership styles and drawing conclusions as to the relationship between leadership styles and culture, more holistic understanding can be attained.

    Full Text Available An organization is considered to be effective if it finds the balance between the demands of various stakeholders (owners, employees, customers, community and the needs of the employees. We believe that an appropriate leadership style can influence and ensure the prosperity and the economic growth of both the organization and employees. Therefore, the aim of the paper is to explore the impact of leadership styles on the organizational performance. Our main focus is on transformational leadership and its role in facilitating the increase in organizational performance. Transformational leaders inspire individuals within the organizations to work harder and to strive for the highest levels of performance. We begin by underlining the connection between transformational leadership and organizational performance, we provide examples on transformational leadership practices’ impact the organizations and we conclude by making some future research propositions.

    This paper presents a numerical investigation of the leading-edge vortices generated by rotating triangular wings at Reynolds number Re = 250. A series of three-dimensional numerical simulations have been carried out using a Fourier pseudo-spectral method with volume penalization. The transition from stable attachment of the leading-edge vortex to periodic vortex shedding is explored, as a function of the wing aspect ratio and the angle of attack. It is found that, in a stable configuration, the spanwise flow in the recirculation bubble past the wing is due to the centrifugal force, incompressibility and viscous stresses. For the flow outside of the bubble, an inviscid model of spanwise flow is presented. (papers)

  17. An overview of two nonlinear supersonic wing design studies (United States)

    Miller, D. S.; Pittman, J. L.; Wood, R. M.


    The progress of two studies which apply nonlinear aerodynamics to supersonic wing design is reviewed. The first study employed a nonlinear potential flow code to design wings for high lift and low drag due to lift by employing a controlled leading-edge expansion in which the crossflow accelerates to supercritical conditions and decelerates through a weak shock. The second study utilized a modified linearized theory code to explore the concept of using 'attainable' leading-edge thrust as a guide for selecting a wing leading-edge shape (planform and radius) for maintaining attached flow and maximizing leading-edge thrust. Experimental and theoretical results obtained during the course of these two studies are discussed.

  18. Developing nursing leadership in social media. (United States)

    Moorley, Calvin; Chinn, Teresa


    A discussion on how nurse leaders are using social media and developing digital leadership in online communities. Social media is relatively new and how it is used by nurse leaders and nurses in a digital space is under explored. Discussion paper. Searches used CINAHL, the Royal College of Nursing webpages, Wordpress (for blogs) and Twitter from 2000-2015. Search terms used were Nursing leadership + Nursing social media. Understanding the development and value of nursing leadership in social media is important for nurses in formal and informal (online) leadership positions. Nurses in formal leadership roles in organizations such as the National Health Service are beginning to leverage social media. Social media has the potential to become a tool for modern nurse leadership, as it is a space where can you listen on a micro level to each individual. In addition to listening, leadership can be achieved on a much larger scale through the use of social media monitoring tools and exploration of data and crowd sourcing. Through the use of data and social media listening tools nursing leaders can seek understanding and insight into a variety of issues. Social media also places nurse leaders in a visible and accessible position as role models. Social media and formal nursing leadership do not have to be against each other, but they can work in harmony as both formal and online leadership possess skills that are transferable. If used wisely social media has the potential to become a tool for modern nurse leadership. © 2016 John Wiley & Sons Ltd.

  19. Increasing women in leadership in global health. (United States)

    Downs, Jennifer A; Reif, Lindsey K; Hokororo, Adolfine; Fitzgerald, Daniel W


    Globally, women experience a disproportionate burden of disease and death due to inequities in access to basic health care, nutrition, and education. In the face of this disparity, it is striking that leadership in the field of global health is highly skewed towards men and that global health organizations neglect the issue of gender equality in their own leadership. Randomized trials demonstrate that women in leadership positions in governmental organizations implement different policies than men and that these policies are more supportive of women and children. Other studies show that proactive interventions to increase the proportion of women in leadership positions within businesses or government can be successful. Therefore, the authors assert that increasing female leadership in global health is both feasible and a fundamental step towards addressing the problem of women's health. In this Perspective, the authors contrast the high proportion of young female trainees who are interested in academic global health early in their careers with the low numbers of women successfully rising to global health leadership roles. The authors subsequently explore reasons for female attrition from the field of global health and offer practical strategies for closing the gender gap in global health leadership. The authors propose solutions aimed to promote female leaders from both resource-wealthy and resource-poor countries, including leadership training grants, mentorship from female leaders in global professions, strengthening health education in resource-poor countries, research-enabling grants, and altering institutional policies to support women choosing a global health career path.

  20. Staff nurse perceptions of nurse manager leadership styles and outcomes. (United States)

    Casida, Jesus; Parker, Jessica


    To explore the correlations of leadership styles of nurse managers (NMs) and outcomes.   Little is known about the linkages among leadership styles [transformational (TFL), transactional (TRL)] of NMs and outcomes [a leader's extra effort (LEE), leadership satisfaction (LS) and effectiveness (LE)] using the full-range leadership theory. Methods  An exploratory correlational design was employed using data from a 2007 study in which staff nurses (n = 278) from four hospitals in the Northeastern US were asked to rate the leadership styles of NMs (n = 37) and outcomes using the Multifactor Leadership Questionnaire Form 5x-Short. Data were analysed using descriptive and inferential statistical methods. TFL leadership has strong correlations to LEE, LS and LE, and was a predictor for leadership outcomes. Conversely, TRL leadership has week correlations to LEE, LS and LE and did not predict leadership outcomes. NMs who frequently display TFL leadership styles will probably achieve goals in a satisfying manner, warranting further research. TFL leadership training should be a basic competency requirement of NMs. Placing successful and effective TFL leaders in nursing units are the professional and moral obligations of nurse executives. © 2011 The Authors.

  1. Details of insect wing design and deformation enhance aerodynamic function and flight efficiency. (United States)

    Young, John; Walker, Simon M; Bomphrey, Richard J; Taylor, Graham K; Thomas, Adrian L R


    Insect wings are complex structures that deform dramatically in flight. We analyzed the aerodynamic consequences of wing deformation in locusts using a three-dimensional computational fluid dynamics simulation based on detailed wing kinematics. We validated the simulation against smoke visualizations and digital particle image velocimetry on real locusts. We then used the validated model to explore the effects of wing topography and deformation, first by removing camber while keeping the same time-varying twist distribution, and second by removing camber and spanwise twist. The full-fidelity model achieved greater power economy than the uncambered model, which performed better than the untwisted model, showing that the details of insect wing topography and deformation are important aerodynamically. Such details are likely to be important in engineering applications of flapping flight.

  2. Optimum Wing Shape of Highly Flexible Morphing Aircraft for Improved Flight Performance (United States)

    Su, Weihua; Swei, Sean Shan-Min; Zhu, Guoming G.


    In this paper, optimum wing bending and torsion deformations are explored for a mission adaptive, highly flexible morphing aircraft. The complete highly flexible aircraft is modeled using a strain-based geometrically nonlinear beam formulation, coupled with unsteady aerodynamics and six-degrees-of-freedom rigid-body motions. Since there are no conventional discrete control surfaces for trimming the flexible aircraft, the design space for searching the optimum wing geometries is enlarged. To achieve high performance flight, the wing geometry is best tailored according to the specific flight mission needs. In this study, the steady level flight and the coordinated turn flight are considered, and the optimum wing deformations with the minimum drag at these flight conditions are searched by utilizing a modal-based optimization procedure, subject to the trim and other constraints. The numerical study verifies the feasibility of the modal-based optimization approach, and shows the resulting optimum wing configuration and its sensitivity under different flight profiles.

  6. Perceptions of leadership among final-year undergraduate nursing students. (United States)

    Francis-Shama, Jayne


    Aim The promotion of a distributed leadership model in health care means there is an expectation that undergraduate training should contribute to the development of nursing students' leadership capabilities. However, there is concern that the nursing degree programme is not sufficiently preparing students. This study explored nursing students' perceptions of leadership before qualifying, and how prepared they felt to take on leadership roles. Method Data were collected from 20 undergraduate nursing students, using a Straussian grounded theory approach, through three focus groups and six semi-structured interviews. Findings These suggest students are disengaged from the learning of leadership, and preparation for leadership in clinical areas is problematic, as students are exposed to flawed role modelling. Conclusion Discrepancies between nurse education and the realities of clinical practice mean that successfully preparing nursing students for leadership roles will be challenging within current provision.

  7. Leadership styles in nursing. (United States)

    Cope, Vicki; Murray, Melanie


    Nurses are often asked to think about leadership, particularly in times of rapid change in healthcare, and where questions have been raised about whether leaders and managers have adequate insight into the requirements of care. This article discusses several leadership styles relevant to contemporary healthcare and nursing practice. Nurses who are aware of leadership styles may find this knowledge useful in maintaining a cohesive working environment. Leadership knowledge and skills can be improved through training, where, rather than having to undertake formal leadership roles without adequate preparation, nurses are able to learn, nurture, model and develop effective leadership behaviours, ultimately improving nursing staff retention and enhancing the delivery of safe and effective care.

  10. Aerodynamic control with passively pitching wings (United States)

    Gravish, Nick; Wood, Robert

    Flapping wings may pitch passively under aerodynamic and inertial loads. Such passive pitching is observed in flapping wing insect and robot flight. The effect of passive wing pitch on the control dynamics of flapping wing flight are unexplored. Here we demonstrate in simulation and experiment the critical role wing pitching plays in yaw control of a flapping wing robot. We study yaw torque generation by a flapping wing allowed to passively rotate in the pitch axis through a rotational spring. Yaw torque is generated through alternating fast and slow upstroke and and downstroke. Yaw torque sensitively depends on both the rotational spring force law and spring stiffness, and at a critical spring stiffness a bifurcation in the yaw torque control relationship occurs. Simulation and experiment reveal the dynamics of this bifurcation and demonstrate that anomalous yaw torque from passively pitching wings is the result of aerodynamic and inertial coupling between the pitching and stroke-plane dynamics.

  11. A comparative study of the hovering efficiency of flapping and revolving wings

    International Nuclear Information System (INIS)

    Zheng, L; Mittal, R; Hedrick, T


    Direct numerical simulations are used to explore the hovering performance and efficiency for hawkmoth-inspired flapping and revolving wings at Reynolds (Re) numbers varying from 50 to 4800. This range covers the gamut from small (fruit fly size) to large (hawkmoth size) flying insects and is also relevant to the design of micro- and nano-aerial vehicles. The flapping wing configuration chosen here corresponds to a hovering hawkmoth and the model is derived from high-speed videogrammetry of this insect. The revolving wing configuration also employs the wings of the hawkmoth but these are arranged in a dual-blade configuration typical of helicopters. Flow for both of these configurations is simulated over the range of Reynolds numbers of interest and the aerodynamic performance of the two compared. The comparison of these two seemingly different configurations raises issues regarding the appropriateness of various performance metrics and even characteristic scales; these are also addressed in the current study. Finally, the difference in the performance between the two is correlated with the flow physics of the two configurations. The study indicates that viscous forces dominate the aerodynamic power expenditure of the revolving wing to a degree not observed for the flapping wing. Consequently, the lift-to-power metric of the revolving wing declines rapidly with decreasing Reynolds numbers resulting in a hovering performance that is at least a factor of 2 lower than the flapping wing at Reynolds numbers less than about 100.

  12. Wing kinematics measurement and aerodynamics of a dragonfly in turning flight. (United States)

    Li, Chengyu; Dong, Haibo


    This study integrates high-speed photogrammetry, 3D surface reconstruction, and computational fluid dynamics to explore a dragonfly (Erythemis Simplicicollis) in free flight. Asymmetric wing kinematics and the associated aerodynamic characteristics of a turning dragonfly are analyzed in detail. Quantitative measurements of wing kinematics show that compared to the outer wings, the inner wings sweep more slowly with a higher angle of attack during the downstroke, whereas they flap faster with a lower angle of attack during the upstroke. The inner-outer asymmetries of wing deviations result in an oval wingtip trajectory for the inner wings and a figure-eight wingtip trajectory for the outer wings. Unsteady aerodynamics calculations indicate significantly asymmetrical force production between the inner and outer wings, especially for the forewings. Specifically, the magnitude of the drag force on the inner forewing is approximately 2.8 times greater than that on the outer forewing during the downstroke. In the upstroke, the outer forewing generates approximately 1.9 times greater peak thrust than the inner forewing. To keep the body aloft, the forewings contribute approximately 64% of the total lift, whereas the hindwings provide 36%. The effect of forewing-hindwing interaction on the aerodynamic performance is also examined. It is found that the hindwings can benefit from this interaction by decreasing power consumption by 13% without sacrificing force generation.

  13. Aerodynamics and Ecomorphology of Flexible Feathers and Morphing Bird Wings (United States)

    Klaassen van Oorschot, Brett

    Birds are talented fliers capable of vertical take-off and landing, navigating turbulent air, and flying thousands of miles without rest. How is this possible? What allows birds to exploit the aerial environment with such ease? In part, it may be because bird wings are unlike any engineered wing. They are flexible, strong, lightweight, and dynamically capable of changes in shape on a nearly instantaneous basis (Rayner, 1988; Tobalske, 2007). Moreover, much of this change is passive, modulated only by changes in airflow angle and velocity. Birds actively morph their wings and their feathers morph passively in response to airflow to meet aerodynamic demands. Wings are highly adapted to myriad aeroecological factors and aerodynamic conditions (e.g. Lockwood et al., 1998; Bowlin and Winkler, 2004). This dissertation contains the results of my research on the complexities of morphing avian wings and feathers. I chose to study three related-but-discrete aspects of the avian wing: 1) the aerodynamics of morphing wings during take-off and gliding flight, 2) the presence and significance of wing tip slots across the avian clade, and 3) the aerodynamic role of the emarginate primary feathers that form these wing tip slots. These experiments ask fundamental questions that have intrigued me since childhood: Why do birds have different wing shapes? And why do some birds have slotted wing tips? It's fair to say that you will not find definitive answers here--rather, you will find the methodical, incremental addition of new hypotheses and empirical evidence which will serve future researchers in their own pursuits of these questions. The first chapter explores active wing morphing in two disparate aerodynamic regimes: low-advance ratio flapping (such as during takeoff) and high-advance ratio gliding. This chapter was published in the Journal of Experimental Biology (Klaassen van Oorschot et al., 2016) with the help of an undergraduate researcher, Emily Mistick. We found that wing

  16. Transcriptome profiling with focus on potential key genes for wing development and evolution in Megaloprepus caerulatus, the damselfly species with the world's largest wings. (United States)

    Feindt, Wiebke; Oppenheim, Sara J; DeSalle, Robert; Goldstein, Paul Z; Hadrys, Heike


    The evolution, development and coloration of insect wings remains a puzzling subject in evolutionary research. In basal flying insects such as Odonata, genomic research regarding bauplan evolution is still rare. Here we focus on the world's largest odonate species-the "forest giant" Megaloprepus caerulatus, to explore its potential for looking deeper into the development and evolution of wings. A recently discovered cryptic species complex in this genus previously considered monotypic is characterized by morphological differences in wing shape and color patterns. As a first step toward understanding wing pattern divergence and pathways involved in adaptation and speciation at the genomic level, we present a transcriptome profiling of M. caerulatus using RNA-Seq and compare these data with two other odonate species. The de novo transcriptome assembly consists of 61,560 high quality transcripts and is approximately 93% complete. For almost 75% of the identified transcripts a possible function could be assigned: 48,104 transcripts had a hit to an InterPro protein family or domain, and 28,653 were mapped to a Gene Ontology term. In particular, we focused on genes related to wing development and coloration. The comparison with two other species revealed larva-specific genes and a conserved 'core' set of over 8,000 genes forming orthologous clusters with Ischnura elegans and Ladona fulva. This transcriptome may provide a first point of reference for future research in odonates addressing questions surrounding the evolution of wing development, wing coloration and their role in speciation.

  18. Mixed ice accretion on aircraft wings (United States)

    Janjua, Zaid A.; Turnbull, Barbara; Hibberd, Stephen; Choi, Kwing-So


    Ice accretion is a problematic natural phenomenon that affects a wide range of engineering applications including power cables, radio masts, and wind turbines. Accretion on aircraft wings occurs when supercooled water droplets freeze instantaneously on impact to form rime ice or runback as water along the wing to form glaze ice. Most models to date have ignored the accretion of mixed ice, which is a combination of rime and glaze. A parameter we term the "freezing fraction" is defined as the fraction of a supercooled droplet that freezes on impact with the top surface of the accretion ice to explore the concept of mixed ice accretion. Additionally we consider different "packing densities" of rime ice, mimicking the different bulk rime densities observed in nature. Ice accretion is considered in four stages: rime, primary mixed, secondary mixed, and glaze ice. Predictions match with existing models and experimental data in the limiting rime and glaze cases. The mixed ice formulation however provides additional insight into the composition of the overall ice structure, which ultimately influences adhesion and ice thickness, and shows that for similar atmospheric parameter ranges, this simple mixed ice description leads to very different accretion rates. A simple one-dimensional energy balance was solved to show how this freezing fraction parameter increases with decrease in atmospheric temperature, with lower freezing fraction promoting glaze ice accretion.

    CERN Document Server

    de Croon, G C H E; Remes, B D W; Ruijsink, R; De Wagter, C


    This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the "Delfly", a flapping wing robot designed at Delft University in The Netherlands. How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard. This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Expl...

  7. Balint group leadership: Conceptual foundations and a framework for leadership development? (United States)

    Elder, Andrew


    This article is based on a talk given at the International Balint Federation leadership congress in Warsaw (September 2016). It explores the conceptual foundations of Balint group leadership and starts by emphasizing the mutuality between psychoanalysts and medical practitioners working together. The parallel process between consulting room and group, and subsequently from group back to the consulting room, is delineated as the central construct in understanding the role of the leader. Having proposed a conceptual model for thinking about leadership interventions, the article discusses developments in some contemporary approaches to leadership: coleadership, the use of role play, psychodrama, pushback, and morale. It concludes by introducing Keats' notion of negative capability as a way of thinking about creativity in Balint group leadership.

  8. Wing area, wing growth and wing loading of common sandpipers Actitis hypoleucos


    Yalden, Derek; Yalden, D. W.


    This study investigates the changes in wing length, area and loading in Common Sandpipers as chicks grow, and as adults add extra mass (during egg-laying or before migration). Common Sandpiper chicks weigh about 17 g and have "hands" that are about 35 mm long at one week old, when the primaries are just emerging from their sheaths. They grow steadily to reach about 40 g, with hands about 85 mm long, at 19 days, when they are just about fledging. Their wings have roughly adult chord width at t...

  9. Leadership styles of Finnish nurse managers and factors influencing it. (United States)

    Vesterinen, Soili; Isola, Arja; Paasivaara, Leena


    The purpose of the present study was to explore nurse managers' perceptions of their leadership styles and factors influencing it. It is a challenge for nurse managers to retain nurses in hospitals and to ensure a high quality of care in nursing practice. Leadership style is an important part of leadership. Knowledge concerning nurse managers' resonant and non-resonant leadership styles provides nurse managers with tools to reflect on their own leadership style. Open-ended, tape-recorded interviews were conducted with 13 nurse managers from five Finnish hospitals and two long-term care facilities. The data were analysed using qualitative content analysis. Five categories of leadership style were discerned: visionary, coaching, affiliate, democratic, commanding. Factors that influence leadership style were identified: earlier superiors, values, information, cooperation, employees and education. The results of this study show that Finnish nurse managers use both resonant and non-resonant leadership styles. The findings of this study show that nurse managers use a variety of leadership styles. The study demonstrates the importance of knowledge about leadership styles and factors influencing it among nurse managers providing future leadership and management education.

  16. Leadership training for postdoctoral dental students. (United States)

    Skoulas, Angelique; Kalenderian, Elsbeth


    Harvard School of Dental Medicine launched a course on leadership for its postdoctoral dental students in 2010 in order to introduce them to the art of leadership and the latest theories and principles regarding becoming a leader. Nine four-hour modules over a period of six months took the students on a journey of leadership self-exploration by building awareness of their capacity in core leadership skills; providing them with tools and frameworks for developing effective leadership skills; encouraging the immediate practice of core skills; creating space for honest reflection; and providing inspiration with guest lectures. A constant toggle between the present and their future as leaders was built into the course. In the student evaluations, the course received an overall rating of 4.71 (5=excellent), and the students reported an enhanced interest in all topic areas. They reported that the ability to build trust with others was the most beneficial skill for a dentist, while viewing advocacy skills as the least beneficial. All the students indicated an intention to continue developing their leadership skills. Through the course, the students developed an understanding of their leadership strengths and limitations through case studies, role-play, and self-reflection, as well as gaining an understanding of team dynamics and cultural perceptions in the context of dentistry.

    Ayoosha Saleem


    Full Text Available This research study has empirically examined the role of leadership in shaping employees’ attitude towards an organizational change/reform in an educational sector organization i.e. Army Public Schools and Colleges System, Pakistan. Data was collected from 95 leaders (principals, wing-heads and coordinators and 250 employees (teachers through convenience sampling technique. Data was analyzed through Hierarchical Linear Modeling (HLM. This study has found that leaders’ and teachers’ dispositional resistance to change were positively related to teachers’ intentions to resist change and leaders’ transformational behaviors had a negative impact on teachers’ intentions to resist change. Furthermore, leaders’ conservation values were positively related to teachers’ resistance intentions whereas leaders’ openness to change values were negatively associated with teachers’ resistance intentions. However, transformational leadership did not moderate the relationship between teachers’ dispositional resistance to change and teachers’ resistance intentions.

  4. Leadership styles: The role of cultural intelligence

    Directory of Open Access Journals (Sweden)

    Anthony Solomon


    Full Text Available Orientation: Within both the South African context and abroad, leaders are increasingly being required to engage with staff members whose cultures differ from their own. As the attractiveness of different leadership styles varies in line with staff member cultural preferences, the challenge leaders face is that their behaviours may no longer be apposite. To this end, it is mostly unknown whether those leaders who are deemed culturally intelligent behave in a specific manner, that is, display the empowering and directive leadership styles. Research purpose: The purpose of this study was to explore the relationship between leader cultural intelligence and the empowering and directive styles of leadership, as perceived by subordinates. Motivation for the study: To operate successfully, leaders need to adopt and display those leadership styles that best match the cultural expectations of their staff members. Cultural intelligence may assist in this respect. Most of the studies on leader cultural intelligence and leadership styles have concentrated on the transformational leadership style. There is, thus, a requirement to examine how leader cultural intelligence relates to other leadership styles. Research design, approach and method: The study was quantitative in nature and made use of a cross-sectional survey design. Data were collected from 1140 staff members spread across 19 diverse organisations carrying on business activities in South Africa. Correlation and regression techniques were performed to identify relationships. Main findings: Leader cultural intelligence was found to have a stronger relationship with empowering leadership than it had with directive leadership. With empowering leadership, leader metacognitive and motivational cultural intelligence acted as important antecedents, whilst for directive leadership, leader’s motivational, cognitive and metacognitive cultural intelligence played a predictive part that carried a medium

  5. Review Results on Wing-Body Interference

    Directory of Open Access Journals (Sweden)

    Frolov Vladimir


    Full Text Available The paper presents an overview of results for wing-body interference, obtained by the author for varied wing-body combinations. The lift-curve slopes of the wing-body combinations are considered. In this paper a discrete vortices method (DVM and 2D potential model for cross-flow around fuselage are used. The circular and elliptical cross-sections of the fuselage and flat wings of various forms are considered. Calculations showed that the value of the lift-curve slopes of the wing-body combinations may exceed the same value for an isolated wing. This result confirms an experimental data obtained by other authors earlier. Within a framework of the used mathematical models the investigations to optimize the wing-body combination were carried. The present results of the optimization problem for the wing-body combination allowed to select the optimal geometric characteristics for configuration to maximize the values of the lift-curve slopes of the wing-body combination. It was revealed that maximums of the lift-curve slopes for the optimal mid-wing configuration with elliptical cross-section body had a sufficiently large relative width of the body (more than 30% of the span wing.

  6. The role of self-efficacy, emotional intelligence and leadership style as attributes of leadership effectiveness

    Directory of Open Access Journals (Sweden)

    Yvette Ramchunder


    Research purpose: The purpose of this study is to explore the relationship between three constructs, namely emotional intelligence, self-efficacy and leadership effectiveness in a policing context. Motivation for this study: In the police sector, there are difficulties in linking leadership to organisational outcomes since common police-leadership measures are affected by multiple contributory factors. This study explores the psychological constructs of emotional intelligence and self-efficacy on the leadership effectiveness of the police. Research design, approach and method: This research adopted a quantitative approach to assess the relationship between emotional intelligence and self-efficacy as attributes of leadership effectiveness. A total of 107 police personnel in commanding positions made up the sample. The measuring instruments used were the Assessing Emotions Scale, the Self-efficacy Scale and the Multifactor Leadership Questionnaire (MLQ Form 5X. Main findings: The results confirmed a positive relationship between emotional intelligence and self-efficacy and leadership effectiveness. The correlations were significant at the 0.01 level (2-tailed. Practical/managerial implications: Emotional intelligence and self-efficacy should be considered as attributes during the selection of leaders in police organisations or used for developmental purposes to enhance these attributes in police leaders. Contribution/value-add: The insights gained from the findings may be used to guide the selection of future leaders in the policing environment, and they could also be used to establish future developmental programmes and research initiatives.

  7. Cross-Cultural Leadership

    Directory of Open Access Journals (Sweden)

    Inga Minelgaite Snaebjornsson


    Full Text Available Ongoing low participation of women in global leadership calls for more research in this field. In this article, we set out to include gendered expectations toward leader behavior as part of cross-cultural leadership theory. Building on an existing body of research, we focus on propositions about the effects of gendered expectations on the leader, from the followers’ standpoint. The consideration of gendered effects from the follower standpoint is an under-researched area in leadership literature, and it is even more rarely to be found in empirical data. In every culture, there are certain expectations toward leaders of the two genders that influence their behavior. In this article, we will attempt to answer the following question: How does perceived leader behavior and gendered behavior relate to national culture and actual leader behavior? We present a conceptual model that seeks to incorporate gendered expectations into cross-cultural leadership as an answer. Moreover, we provide a conceptual guideline toward operationalization of the model. The model includes the potential of dissonance between male expectations as a dominating leadership role and female leadership. This might serve as an explanation as to why in some cases women are not seen as successful as men when they adopt a masculine leadership style. The article seeks to advance cross-cultural leadership theory by focusing on expected gendered leadership behavior. Our ideas and model could eventually contribute to the advancement of leadership theory, as well as contributing to gender studies, cross-cultural leadership, and business communication.

  18. A Drosophila wing spot test

    International Nuclear Information System (INIS)

    Ayaki, Toshikazu; Yoshikawa, Isao; Niikawa, Norio; Hoshi, Masaharu.


    A Drosophila wing spot test system was used to investigate the effects of low doses of X-rays, gamma rays, and both 2.3 and 14.1 MeV neutrons on somatic chromosome mutation (SCM) induction. The incidence of SCM was significantly increased with any type of radiation, with evident linear dose-response relationship within the range of 3 to 20 cGy. It was estimated that relative biological effectiveness value for SCM induction of 2.3 MeV neutrons to X-rays and gamma rays is much higher than that of 14.1 MeV neutrons to those photons (2.4 vs 8.0). The Drosophila wing spot test system seems to become a promising in vivo experimental method for higher animals in terms of the lack of necessity for a marvelously large number of materials required in conventional test system.

  19. Leadership and learning disability nursing. (United States)

    Jukes, Mark; Aspinall, Susan-Louise

    Leadership is seen as critical for the transformation of learning disability services and has been further emphasised since the publication of Transforming Care, the Department of Health's response to the review of events at Winterbourne View. What is clear within learning disability nursing and services is the demand for leadership in the quest for improving the quality and effectiveness of services across health and social care. This article discusses the challenges for the undergraduate learning disability nurse with the recommendation to pursue a framework that promotes and focuses on integrating knowledge transfer into services for people with a learning disability. It explores practice change using the Promoting Action on Research Implementation in Health Services (PARiHS) framework, and the example of the involvement of service users in practitioner training on the Mental Capacity Act 2005 and consent and capacity to consent for treatment.

  20. Consumers in mental health service leadership: A systematic review. (United States)

    Scholz, Brett; Gordon, Sarah; Happell, Brenda


    Contemporary mental health policies call for greater involvement of mental health service consumers in all aspects and at all levels of service planning, delivery, and evaluation. The extent to which consumers are part of the decision-making function of mental health organizations varies. This systematic review synthesizes empirical and review studies published in peer-reviewed academic journals relating to consumers in leadership roles within mental health organizations. The Cochrane Library, Medline, and PsycINFO were searched for articles specifically analysing and discussing consumers' mental health service leadership. Each article was critically appraised against the inclusion criteria, with 36 articles included in the final review. The findings of the review highlight current understandings of organizational resources and structures in consumer-led organizations, determinants of leadership involvement, and how consumer leadership interacts with traditional mental health service provision. It appears that organizations might still be negotiating the balance between consumer leadership and traditional structures and systems. The majority of included studies represent research about consumer-run organizations, with consumer leadership in mainstream mental health organizations being less represented in the literature. Advocates of consumer leadership should focus more on emphasizing how such leadership itself can be a valuable resource for organizations and how this can be better articulated. This review highlights the current gaps in understandings of consumer leadership in mental health, including a need for more research exploring the benefits of consumer leadership for other consumers of services. © 2016 Australian College of Mental Health Nurses Inc.

  1. Collaborating internationally on physician leadership development: why now? (United States)

    Chan, Ming-Ka; de Camps Meschino, Diane; Dath, Deepak; Busari, Jamiu; Bohnen, Jordan David; Samson, Lindy Michelle; Matlow, Anne; Sánchez-Mendiola, Melchor


    Purpose This paper aims to highlight the importance of leadership development for all physicians within a competency-based medical education (CBME) framework. It describes the importance of timely international collaboration as a key strategy in promoting physician leadership development. Design/methodology/approach The paper explores published and Grey literature around physician leadership development and proposes that international collaboration will meet the expanding call for development of leadership competencies in postgraduate medical learners. Two grounding frameworks were used: complexity science supports adding physician leadership training to the current momentum of CBME adoption, and relational cultural theory supports the engagement of diverse stakeholders in multiple jurisdictions around the world to ensure inclusivity in leadership education development. Findings An international collaborative identified key insights regarding the need to frame physician leadership education within a competency-based model. Practical implications International collaboration can be a vehicle for developing a globally relevant, generalizable physician leadership curriculum.

  2. Aerodynamic effects of flexibility in flapping wings (United States)

    Zhao, Liang; Huang, Qingfeng; Deng, Xinyan; Sane, Sanjay P.


    Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast, wings flapping at high angles of attack generate stable leading edge vorticity, which persists throughout the duration of the stroke and enhances mean aerodynamic forces. Here, we show that aerodynamic forces can be controlled by altering the trailing edge flexibility of a flapping wing. We used a dynamically scaled mechanical model of flapping flight (Re ≈ 2000) to measure the aerodynamic forces on flapping wings of variable flexural stiffness (EI). For low to medium angles of attack, as flexibility of the wing increases, its ability to generate aerodynamic forces decreases monotonically but its lift-to-drag ratios remain approximately constant. The instantaneous force traces reveal no major differences in the underlying modes of force generation for flexible and rigid wings, but the magnitude of force, the angle of net force vector and centre of pressure all vary systematically with wing flexibility. Even a rudimentary framework of wing veins is sufficient to restore the ability of flexible wings to generate forces at near-rigid values. Thus, the magnitude of force generation can be controlled by modulating the trailing edge flexibility and thereby controlling the magnitude of the leading edge vorticity. To characterize this, we have generated a detailed database of aerodynamic forces as a function of several variables including material properties, kinematics, aerodynamic forces and centre of pressure, which can also be used to help validate computational models of aeroelastic flapping wings. These experiments will also be useful for wing design for small robotic

    Full Text Available Previous studies have provided valuable insights into the impact of culture on the concept of leadership communication. However, only a few studies that focused on exploring and understanding the values of Confucianism and its impact on the Chinese culture, especially in Malaysia. Thus, this study is among the first study to examine the leadership communication from the perspective of Confucianism towards the leadership of Dr. Mahathir from the perspective of the Chinese community in Malaysia. This study aims to assess the role of Confucian values in Dr. Mahathir’s leadership communication. This study interviewed 15 Chinese leaders. The findings reveal that three main Confucian values are relevant to Dr. Mahathir’s leadership communication. The Confucian values are Zhi (wisdom, Xin (trust and Xiao (filial piety. This study provides a new perspective on leadership communication from the context of cultural diversity in Malaysia which emphasizes on Confucian values.

  5. Dedicated Education Units: Partnerships for Building Leadership Competency. (United States)

    Galuska, Lee A


    To enable nurses to lead in health care transformation, nursing education must include opportunities for developing leadership, as well as clinical competencies. Dedicated education units (DEUs) provide supportive environments for competency development in undergraduate students. This study's aim was to explore the effects of a DEU experience on the leadership development of baccalaureate nursing students. A mixed-methods design included a quantitative strand, using a quasi-experimental, pretest-posttest, multisite design with control groups and a qualitative strand using focus groups. Students in the DEUs demonstrated significant increases (p leadership behaviors, as measured by the Student Leadership Practice Inventory. Focus group themes illuminate how the experiences of the students contributed to their leadership growth. Findings suggest that the DEU experience may promote enhanced undergraduate leadership competency development. Copyright 2015, SLACK Incorporated.

  6. The Relationship Between Personality Type And Leadership Focus

    Grant Sieff


    Full Text Available Optimising focus is a key success driver for many organisation leaders. The relationship between personality type and leadership focus is examined. Personality type is assessed with Form M of the Myers-Briggs Type Indicator instrument, and leadership focus is explored through the development and application of a Leadership Focus Questionnaire. South African executives form the target population for this study. Both functionalist and interpretive approaches are applied. Three primary theoretical hypotheses about leadership focus, concerning (1 optimising the balance of focus between external and internal priorities, (2 the fit between the leadership personality type and the organisation type, and (3 the capacity to manage a multiple focus, are considered. Results show that Extraverted personality types are more comfortable with the challenges of focus in the leadership role than are Introverted types, and Extraverted, Sensing, Thinking and Judging types experience a greater degree of fit with their organisations than do Introverted, Intuitive, Feeling and Perceiving types.

  8. The relationship between leadership styles and empathy among student nurses. (United States)

    Gunther, Mary; Evans, Ginger; Mefford, Linda; Coe, Thomas R


    Much of the nursing literature on leadership describes the qualities of existing nursing leaders, while emphasizing the need for leadership development in student nurses for both managerial and clinical practice. However, there is a lack of research literature on the characteristics of current students. Conducted by the University of Tennessee College of Nursing Empathy Research Group, this pilot study explores the relationship between leadership styles and empathy (cognitive and affective) levels. This correlational descriptive study involved self-report using 3 instruments. Hogan Empathy Scale (HES) and Emotional Empathy Tendency Scale (EETS) measured cognitive and affective empathy levels. The Multifactoral Leadership Questionnaire (MLQ-5x) was used to determine leadership style. Data analysis yielded evidence of a weak positive correlation between the predominant transformational leadership style and empathy levels in both junior and senior students. This correlation has implications for both nurse educators and future employers.

  9. Effects of wing locations on wing rock induced by forebody vortices

    Directory of Open Access Journals (Sweden)

    Ma Baofeng


    Full Text Available Previous studies have shown that asymmetric vortex wakes over slender bodies exhibit a multi-vortex structure with an alternate arrangement along a body axis at high angle of attack. In this investigation, the effects of wing locations along a body axis on wing rock induced by forebody vortices was studied experimentally at a subcritical Reynolds number based on a body diameter. An artificial perturbation was added onto the nose tip to fix the orientations of forebody vortices. Particle image velocimetry was used to identify flow patterns of forebody vortices in static situations, and time histories of wing rock were obtained using a free-to-roll rig. The results show that the wing locations can affect significantly the motion patterns of wing rock owing to the variation of multi-vortex patterns of forebody vortices. As the wing locations make the forebody vortices a two-vortex pattern, the wing body exhibits regularly divergence and fixed-point motion with azimuthal variations of the tip perturbation. If a three-vortex pattern exists over the wing, however, the wing-rock patterns depend on the impact of the highest vortex and newborn vortex. As the three vortices together influence the wing flow, wing-rock patterns exhibit regularly fixed-points and limit-cycled oscillations. With the wing moving backwards, the newborn vortex becomes stronger, and wing-rock patterns become fixed-points, chaotic oscillations, and limit-cycled oscillations. With further backward movement of wings, the vortices are far away from the upper surface of wings, and the motions exhibit divergence, limit-cycled oscillations and fixed-points. For the rearmost location of the wing, the wing body exhibits stochastic oscillations and fixed-points.

  14. Context and the leadership experiences and perceptions of professionals: a review of the nursing profession. (United States)

    Jefferson, Therese; Klass, Des; Lord, Linley; Nowak, Margaret; Thomas, Gail


    Leadership studies which focus on categorising leadership styles have been critiqued for failure to consider the lived experience of leadership. The purpose of this paper is to use the framework of Jepson's model of contextual dynamics to explore whether this framework assists understanding of the "how and why" of lived leadership experience within the nursing profession. Themes for a purposeful literature search and review, having regard to the Jepson model, are drawn from the contemporary and dynamic context of nursing. Government reports, coupled with preliminary interviews with a nurseleadership team, guided selection of contextual issues. The contextual interactions arising from managerialism, existing hierarchical models of leadership and increasing knowledge work provided insights into leadership experience in nursing, in the contexts of professional identity and changing educational and generational profiles of nurses. The authors conclude that employing a contextual frame provides insights in studying leadership experience. The author propose additions to the cultural and institutional dimensions of Jepson's model. The findings have implications for structuring and communicating key roles and policies relevant to nursing leadership. These include the need to: address perceptions around the legitimacy of current nursing leaders to provide clinical leadership; modify hierarchical models of nursing leadership; address implications of the role of the knowledge workers. Observing nursing leadership through the lens of Jepson's model of contextual dynamics confirms that this is an important way of exploring how leadership is enacted. The authors found, however, the model also provided a useful frame for considering the experience and understanding of leadership by those to be led.

  17. Role of wing morphing in thrust generation

    Directory of Open Access Journals (Sweden)

    Mehdi Ghommem


    Full Text Available In this paper, we investigate the role of morphing on flight dynamics of two birds by simulating the flow over rigid and morphing wings that have the characteristics of two different birds, namely the Giant Petrel and Dove Prion. The simulation of a flapping rigid wing shows that the root of the wing should be placed at a specific angle of attack in order to generate enough lift to balance the weight of the bird. However, in this case the generated thrust is either very small, or even negative, depending on the wing shape. Further, results show that morphing of the wing enables a significant increase in the thrust and propulsive efficiency. This indicates that the birds actually utilize some sort of active wing twisting and bending to produce enough thrust. This study should facilitate better guidance for the design of flapping air vehicles.

  18. Searching for ethical leadership in nursing. (United States)

    Makaroff, Kara Schick; Storch, Janet; Pauly, Bernie; Newton, Lorelei


    Attention to ethical leadership in nursing has diminished over the past several decades. The aim of our study was to investigate how frontline nurses and formal nurse leaders envision ethical nursing leadership. Meta-ethnography was used to guide our analysis and synthesis of four studies that explored the notion of ethical nursing leadership. These four original studies were conducted from 1999-2008 in Canada with 601 participants. Ethical approval from the original studies covered future analysis. Using the analytic strategy of lines-of-argument, we found that 1) ethical nursing leadership must be responsive to practitioners and to the contextual system in which they and formal nurse leaders work, and 2) ethical nursing leadership requires receiving and providing support to increase the capacity to practice and discuss ethics in the day-to-day. Formal nurse leaders play a critical, yet often neglected role, in providing ethical leadership and supporting ethical nursing practice at the point of patient care. © The Author(s) 2014.

    To explore general practitioners' (GPs) views on leadership roles and leadership challenges in general practice and primary health care. We conducted focus groups (FGs) with 17 GPs. Norwegian primary health care. 17 GPs who attended a 5 d course on leadership in primary health care. Our study suggests that the GPs experience a need for more preparation and formal training for the leadership role, and that they experienced tensions between the clinical and leadership role. GPs recognized the need to take on leadership roles in primary care, but their lack of leadership training and credentials, and the way in which their practices were organized and financed were barriers towards their involvement. GPs experience tensions between the clinical and leadership role and note a lack of leadership training and awareness. There is a need for a more structured educational and career path for GPs, in which doctors are offered training and preparation in advance. KEY POINTS Little is known about doctors' experiences and views about leadership in general practice and primary health care. Our study suggests that: There is a lack of preparation and formal training for the leadership role. GPs experience tensions between the clinical and leadership role. GPs recognize leadership challenges at a system level and that doctors should take on leadership roles in primary health care.

  13. Strong leadership: the case for global connections. (United States)

    Rosser, Elizabeth A; Scammell, Janet; Bevan, Ann; Hundley, Vanora A


    To identify how nurse leaders view and experience the opportunities offered by one of the largest global nursing organisations Sigma Theta Tau International. Worldwide, nursing leadership is challenged with addressing the complex issues impacting on care delivery. International nursing organisations are a means to bring together individuals to promote leadership and scholarship for nursing practice to promote patient safety and quality care. The newly established all-England chapter of Sigma Theta Tau International is a recent addition to the society in terms of nurse leadership in Europe, as such faces challenges as it establishes its identity and seeks to interpret the organisational vision: to advance world health through nursing leadership and scholarship. Moving forward, members views were sought on the goals of the chapter and how they may be enacted. In July 2013, all chapter members at that time had been nominated on the basis of achievement in nurse leadership; all were invited to participate in an online survey. The online questionnaire contained a series of closed and open questions. Most respondents joined because they believed in the vision and networking opportunities Sigma Theta Tau International provides. Three themes were extracted from the data: the value of networking and communication, leadership and the development of culturally sensitive organisations and the need for shared scholarship for nursing practice. Findings indicate the growth of effective leadership at all levels of nursing could be harnessed through successful collaboration and keen support for robust connections between practice and education to promote quality care. Whilst challenging, globalisation presents an opportunity for a nursing society such as Sigma Theta Tau International to work collaboratively to address healthcare issues. A nursing society that explores and resolves its own complex issues by actively promoting leadership and collaborative scholarship reveals a

  14. Analysis of bat wings for morphing (United States)

    Leylek, Emily A.; Manzo, Justin E.; Garcia, Ephrahim


    The morphing of wings from three different bat species is studied using an extension of the Weissinger method. To understand how camber affects performance factors such as lift and lift to drag ratio, XFOIL is used to study thin (3% thickness to chord ratio) airfoils at a low Reynolds number of 100,000. The maximum camber of 9% yielded the largest lift coefficient, and a mid-range camber of 7% yielded the largest lift to drag ratio. Correlations between bat wing morphology and flight characteristics are covered, and the three bat wing planforms chosen represent various combinations of morphological components and different flight modes. The wings are studied using the extended Weissinger method in an "unmorphed" configuration using a thin, symmetric airfoil across the span of the wing through angles of attack of 0°-15°. The wings are then run in the Weissinger method at angles of attack of -2° to 12° in a "morphed" configuration modeled after bat wings seen in flight, where the camber of the airfoils comprising the wings is varied along the span and a twist distribution along the span is introduced. The morphed wing configurations increase the lift coefficient over 1000% from the unmorphed configuration and increase the lift to drag ratio over 175%. The results of the three different species correlate well with their flight in nature.

  15. Veins improve fracture toughness of insect wings.

    Directory of Open Access Journals (Sweden)

    Jan-Henning Dirks

    Full Text Available During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect's flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material's resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04±0.25 MPa√m. However, the cross veins increase the wing's toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 µm. This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically 'optimal' solution with high toughness and low weight. The vein pattern found in insect wings thus might inspire the design of more durable and lightweight artificial 'venous' wings for micro-air-vehicles. Using the vein spacing as indicator, our approach might also provide a basis to estimate the wing properties of endangered or extinct insect species.

  17. Misconceiving medical leadership. (United States)

    Parker, Malcolm


    Medical leadership and leadership education have recently emerged as subjects of an expanding though as yet uncritical literature. Considerable attention is being given to the development of courses and electives, together with some proposals for generalizing these offerings to all medical students and doctors. This article briefly sketches this development and its derivation from business and corporate leadership models and accompanying literature, and subjects its adoption by medicine to critical scrutiny. Putative motivations for these developments are discussed, and an alternative explanation is offered, tied to the loss of physician status. The nature of leadership as complex, emergent, and unpredictable has been ignored in the promotion of medical leadership and leadership training, and this is reflected in the false assumption that leadership in medicine is something that can be taught. Although the leadership literature is beginning to recognize these complex aspects of leadership, so far their implications have not been acknowledged. This article aims to stimulate further analytic discussion of this under-theorized aspect of medicine.

    Bing Li


    Full Text Available This article proposes a camber morphing wing model that can continuously change its camber. A mathematical model is proposed and a kinematic simulation is performed to verify the wing’s ability to change camber. An aerodynamic model is used to test its aerodynamic characteristics. Some important aerodynamic analyses are performed. A comparative analysis is conducted to explore the relationships between aerodynamic parameters, the rotation angle of the trailing edge, and the angle of attack. An improved artificial fish swarm optimization algorithm is proposed, referred to as the weighted adaptive artificial fish-swarm with embedded Hooke–Jeeves search method. Some comparison tests are used to test the performance of the improved optimization algorithm. Finally, the proposed optimization algorithm is used to optimize the proposed camber morphing wing model.

  2. Structural design studies of a supersonic cruise arrow wing configuration (United States)

    Sobieszczanski, J.; Mccullers, L. A.; Ricketts, R. H.; Santoro, N. J.; Beskenis, S. D.; Kurtze, W. L.


    Structural member cross sections were sized with a system of integrated computer programs to satisfy strength and flutter design requirements for several variants of the arrow wing supersonic cruise vehicle. The resulting structural weights provide a measure of the structural efficiency of the planform geometry, structural layout, type of construction, and type of material including composites. The material distribution was determined for a baseline metallic structure and the results indicate that an approximate fatigue constraint has an important effect on the structural weight required for strength but, in all cases, additional material had to be added to satisfy flutter requirements with lighter mass engines with minimum fuel onboard. The use of composite materials on the baseline configuration was explored and indicated increased structural efficiency. In the strength sizing, the all-composite construction provided a lower weight design than the hybrid construction which contained composites only in the wing cover skins. Subsequent flutter analyses indicated a corresponding lower flutter speed.

  11. Situational theory of leadership. (United States)

    Waller, D J; Smith, S R; Warnock, J T


    The situational theory of leadership and the LEAD instruments for determining leadership style are explained, and the application of the situational leadership theory to the process of planning for and implementing organizational change is described. Early studies of leadership style identified two basic leadership styles: the task-oriented autocratic style and the relationship-oriented democratic style. Subsequent research found that most leaders exhibited one of four combinations of task and relationship behaviors. The situational leadership theory holds that the difference between the effectiveness and ineffectiveness of the four leadership styles is the appropriateness of the leader's behavior to the particular situation in which it is used. The task maturity of the individual or group being led must also be accounted for; follower readiness is defined in terms of the capacity to set high but attainable goals, willingness or ability to accept responsibility, and possession of the necessary education or experience for a specific task. A person's leadership style, range, and adaptability can be determined from the LEADSelf and LEADOther questionnaires. By applying the principles of the situational leadership theory and adapting their managerial styles to specific tasks and levels of follower maturity, the authors were successful in implementing 24-hour pharmacokinetic dosing services provided by staff pharmacists with little previous experience in clinical services. The situational leadership model enables a leader to identify a task, set goals, determine the task maturity of the individual or group, select an appropriate leadership style, and modify the style as change occurs. Pharmacy managers can use this model when implementing clinical pharmacy services.

Results from a study in the health care context, including two waves of data from 222 employees, revealed that servant leadership had a small but positive effect on followers’ leadership avoidance. This effect was influenced by followers’ implicit conception of an ideal leader. Specifically, servant leadership was found to reduce leadership avoidanc...

  13. Leadership theory: implications for developing dental surgeons in primary care? (United States)

    Willcocks, S


    The development of leadership in healthcare has been seen as important in recent years, particularly at the clinical level. There have been various specific initiatives focusing on the development of leadership for doctors, nurses and other health care professions: for example, a leadership competency framework for doctors, the LEO programme and the RCN clinical leadership programme for nurses. The NHS has set up a Leadership Council to coordinate further developments. However, there has not been the same focus in dentistry, although the recent review of NHS dental services (Steele review) has proposed a need for leadership initiatives in NHS dentistry as a medium-term action. Central to this will be a need to focus on the leadership role for dental surgeons. Leadership is all the more important in dentistry, given the change of government and the policy of retrenchment, major public sector reform, the emergence of new organisations such as new commissioning consortia, possible changes to the dental contract, new ways of working, and changes to the profession such as the requirements for the revalidation of dental surgeons. The question is: which leadership theory or approach is best for dental surgeons working in primary care? This paper builds on earlier work exploring this question in relation to doctors generally, and GPs, in particular, and planned work on nurses. It will seek to address this question in relation to dental surgeons working in primary care.

  14. Identifying challenges for academic leadership in medical universities in Iran. (United States)

    Bikmoradi, Ali; Brommels, Mats; Shoghli, Alireza; Khorasani-Zavareh, Davoud; Masiello, Italo


    CONTEXT The crucial role of academic leadership in the success of higher education institutions is well documented. Medical education in Iran has been integrated into the health care system through a complex organisational change. This has called into question the current academic leadership, making Iranian medical universities and schools a good case for exploring the challenges of academic leadership. OBJECTIVES This study explores the leadership challenges perceived by academic managers in medical schools and universities in Iran. METHODS A qualitative study using 18 face-to-face, in-depth interviews with academic managers in medical universities and at the Ministry of Health and Medical Education in Iran was performed. All interviews were recorded digitally, transcribed verbatim and analysed by qualitative content analysis. RESULTS The main challenges to academic leadership could be categorised under three themes, each of which included three sub-themes: organisational issues (inefficacy of academic governance; an overly extensive set of missions and responsibilities; concerns about the selection of managers); managerial issues (management styles; mismatch between authority and responsibilities; leadership capabilities), and organisational culture (tendency towards governmental management; a boss-centred culture; low motivation). CONCLUSIONS This study emphasises the need for academic leadership development in Iranian medical schools and universities. The ability of Iranian universities to grow and thrive will depend ultimately upon the application of leadership skills. Thus, it is necessary to better designate authorities, roles of academic staff and leaders at governance.

  15. Conceptualizations of clinical leadership: a review of the literature (United States)

    Mianda, Solange; Voce, Anna S


    Introduction Poor patient outcomes in South African maternal health settings have been associated with inadequately performing health care providers and poor clinical leadership at the point of care. While skill deficiencies among health care providers have been largely addressed, the provision of clinical leadership has been neglected. In order to develop and implement initiatives to ensure clinical leadership among frontline health care providers, a need was identified to understand the ways in which clinical leadership is conceptualized in the literature. Design Using the systematic quantitative literature review, papers published between 2004 and 2016 were obtained from search engines (Google Scholar and EBSCOhost). Electronic databases (CINHAL, PubMed, Medline, Academic Search Complete, Health Source: Consumer, Health Source: Nursing/Academic, ScienceDirect and Ovid®) and electronic journals (Contemporary Nurse, Journal of Research in Nursing, Australian Journal of Nursing and Midwifery, International Journal of Clinical Leadership) were also searched. Results Using preselected inclusion criteria, 7256 citations were identified. After screening 230 potentially relevant full-text papers for eligibility, 222 papers were excluded because they explored health care leadership or clinical leadership among health care providers other than frontline health care providers. Eight papers met the inclusion criteria for the review. Most studies were conducted in high-income settings. Conceptualizations of clinical leadership share similarities with the conceptualizations of service leadership but differ in focus, with the intent of improving direct patient care. Clinical leadership can be a shared responsibility, performed by every competent frontline health care provider, regardless of the position in the health care system. Conclusion Conceptualizations of clinical leadership among frontline health care providers arise mainly from high-income settings. Understanding the

  11. The Realization and Study of Optical Wings (United States)

    Artusio-Glimpse, Alexandra Brae

    Consider the airfoil: a carefully designed structure capable of stable lift in a uniform air flow. It so happens that air pressure and radiation (light) pressure are similar phenomena because each transfer momentum to flow-disturbing objects. This, then, begs the question: does an optical analogue to the airfoil exist? Though an exceedingly small effect, scientists harness radiation pressure in a wide gamut of applications from micromanipulation of single biological particles to the propulsion of large spacecrafts called solar sails. We introduce a cambered, refractive rod that is subjected to optical forces analogous to those seen in aerodynamics, and I call this analogue the optical wing. Flight characteristics of optical wings are determined by wing shape and material in a uniform radiation field. Theory predicts the lift force and axial torque are functions of the wing's angle of attack with stable and unstable orientations. These structures can operate as intensity-dependent, parametrically driven oscillators. In two-dimensions, the wings exhibit bistability when analyzed in an accelerating frame. In three-dimensions, the motion of axially symmetric spinning hemispherical wings is analogous to a spinning top. Experiments on semi-buoyant wings in water found semicylindrically shaped, refractive microparticles traversed a laser beam and rotated to an illumination-dependent stable orientation. Preliminary tests aid in the development of a calibrated force measurement experiment to directly evaluate the optical forces and torque on these samples. A foundational study of the optical wing, this work contributes to future advancements of flight-by-light.

  13. Veins Improve Fracture Toughness of Insect Wings (United States)

    Dirks, Jan-Henning; Taylor, David


    During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect’s flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material’s resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04±0.25 MPa√m). However, the cross veins increase the wing’s toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 µm). This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically ‘optimal’ solution with high toughness and low weight. The vein pattern found in insect wings thus might inspire the design of more durable and lightweight artificial ‘venous’ wings for micro-air-vehicles. Using the vein spacing as indicator, our approach might also provide a basis to estimate the wing properties of endangered or extinct insect species. PMID:22927966

  14. Effect of leading edge roundness on a delta wing in wing-rock motion (United States)

    Ng, T. Terry; Malcolm, Gerald N.


    The effect of wing leading-edge roundness on wing rock was investigated using flow visualization in a water tunnel. Eighty degree delta wing models were tested on free-to-roll and forced oscillation rigs. The onset of wing rock was delayed by increasing the roundness of the leading edges. The wing rock amplitude and frequency results suggested that damping was increased at lower angles of attack but reduced at higher angles of attack. Vortex lift-off and vortex breakdown, especially during dynamic situations, were strongly affected by the leading edge roundness. Different forms of wing rock motion could be sustained by combinations of vortex breakdown and vortex lift-off. Behaviors of the wing and vortex motions were explained by the influence of leading edge roundness on the separation location, vortex trajectory, and vortex breakdown.

  15. What serial homologs can tell us about the origin of insect wings [version 1; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    Yoshinori Tomoyasu


    Full Text Available Although the insect wing is a textbook example of morphological novelty, the origin of insect wings remains a mystery and is regarded as a chief conundrum in biology. Centuries of debates have culminated into two prominent hypotheses: the tergal origin hypothesis and the pleural origin hypothesis. However, between these two hypotheses, there is little consensus in regard to the origin tissue of the wing as well as the evolutionary route from the origin tissue to the functional flight device. Recent evolutionary developmental (evo-devo studies have shed new light on the origin of insect wings. A key concept in these studies is “serial homology”. In this review, we discuss how the wing serial homologs identified in recent evo-devo studies have provided a new angle through which this century-old conundrum can be explored. We also review what we have learned so far from wing serial homologs and discuss what we can do to go beyond simply identifying wing serial homologs and delve further into the developmental and genetic mechanisms that have facilitated the evolution of insect wings.

  16. Leadership in research

    International Nuclear Information System (INIS)

    Lee, N.-J.; Gambling, T.G.; Hogg, P.


    Research to underpin clinical activity in radiographic practice is rapidly becoming a requirement and not an option. Whilst it is recognised that the ability to undertake research demands suitable training in research itself, arguments have been given which indicate that without adequate leadership abilities the research activity may not develop or flourish. In the context of radiography this review paper initially argues a need for research leadership in the clinical (and academic) environment. The debate then moves to consider one method of leadership (transformational) that might be suitable. Transformational leadership is rapidly gaining popularity within the National Health Service. Finally, the debate focuses on the professional ('taught') doctorate as a means of acquiring both research and leadership training and education within one university course

  18. Leadership strategies in healthcare. (United States)

    Menaker, Ronald


    Healthcare is one of the largest and most important industries in the United States because it affects every individual in the nation. Numerous parties are stakeholders in healthcare, which contributes to the complexity of change efforts. Physicians and administrators play a significant role by providing direct care and influencing other decisions that impact the delivery of patient care. Success in the healthcare industry is influenced by numerous factors, some of which are controllable and others that are not. Understanding leadership and change management will be increasingly important to overcome resistance to change and to improve relationships, the core of leadership in an environment that will become more challenging. In what follows, different approaches to understanding leadership and change management are presented along with other leadership strategies to enhance the effectiveness of leaders. Raising leader awareness regarding transformational leadership behaviors and developing strategies to increase the use of these behaviors may be helpful to enhance organizational performance.

  20. Leadership and the Church: The Impact of Shifting Leadership Constructs

    Directory of Open Access Journals (Sweden)

    Douglas Gautsch


    Full Text Available The idea of leadership has been examined for millennia. Examples of leadership in action go back to Moses from the Bible and Xenophón from Greek history.  One of the key theories in early leadership is that of charismatic leadership. Although most scholars agree that a key concept of charismatic leadership is that of follower attribution, defining boundaries for charismatic is as difficult as defining leadership itself. This difficulty is accentuated in this work because of the shifting organizational structures and follower perceptions. The case details follower attributed charismatic leadership traits, and then provides a robust discussion on the impact of shifting organizational constructs.

  4. Nanofabrication and coloration study of artificial Morpho butterfly wings with aligned lamellae layers (United States)

    Zhang, Sichao; Chen, Yifang


    The bright and iridescent blue color from Morpho butterfly wings has attracted worldwide attentions to explore its mysterious nature for long time. Although the physics of structural color by the nanophotonic structures built on the wing scales has been well established, replications of the wing structure by standard top-down lithography still remains a challenge. This paper reports a technical breakthrough to mimic the blue color of Morpho butterfly wings, by developing a novel nanofabrication process, based on electron beam lithography combined with alternate PMMA/LOR development/dissolution, for photonic structures with aligned lamellae multilayers in colorless polymers. The relationship between the coloration and geometric dimensions as well as shapes is systematically analyzed by solving Maxwell’s Equations with a finite domain time difference simulator. Careful characterization of the mimicked blue by spectral measurements under both normal and oblique angles are carried out. Structural color in blue reflected by the fabricated wing scales, is demonstrated and further extended to green as an application exercise of the new technique. The effects of the regularity in the replicas on coloration are analyzed. In principle, this approach establishes a starting point for mimicking structural colors beyond the blue in Morpho butterfly wings. PMID:26577813

  5. Expression of Genes Involved in Drosophila Wing Morphogenesis and Vein Patterning Are Altered by Spaceflight (United States)

    Parsons-Wingerter, Patricia A.; Hosamani, Ravikumar; Bhattacharya, Sharmila


    Imaginal wing discs of Drosophila melanogaster (fruit fly) defined during embryogenesis ultimately result in mature wings of stereotyped (specific) venation patterning. Major regulators of wing disc development are the epidermal growth factor receptor (EGF), Notch, Hedgehog (Hh), Wingless (Wg), and Dpp signaling pathways. Highly stereotyped vascular patterning is also characteristic of tissues in other organisms flown in space such as the mouse retina and leaves of Arabidopsis thaliana. Genetic and other adaptations of vascular patterning to space environmental factors have not yet been systematically quantified, despite widespread recognition of their critical importance for terrestrial and microgravity applications. Here we report changes in gene expression with space flight related to Drosophila wing morphogenesis and vein patterning. In addition, genetically modified phenotypes of increasingly abnormal ectopic wing venation in the Drosophila wing1 were analyzed by NASA's VESsel GENeration Analysis (VESGEN) software2. Our goal is to further develop insightful vascular mappings associated with bioinformatic dimensions of genetic or other molecular phenotypes for correlation with genetic and other molecular profiling relevant to NASA's GeneLab and other Space Biology exploration initiatives.

  6. Can complexity science inform physician leadership development? (United States)

    Grady, Colleen Marie


    Purpose The purpose of this paper is to describe research that examined physician leadership development using complexity science principles. Design/methodology/approach Intensive interviewing of 21 participants and document review provided data regarding physician leadership development in health-care organizations using five principles of complexity science (connectivity, interdependence, feedback, exploration-of-the-space-of-possibilities and co-evolution), which were grouped in three areas of inquiry (relationships between agents, patterns of behaviour and enabling functions). Findings Physician leaders are viewed as critical in the transformation of healthcare and in improving patient outcomes, and yet significant challenges exist that limit their development. Leadership in health care continues to be associated with traditional, linear models, which are incongruent with the behaviour of a complex system, such as health care. Physician leadership development remains a low priority for most health-care organizations, although physicians admit to being limited in their capacity to lead. This research was based on five principles of complexity science and used grounded theory methodology to understand how the behaviours of a complex system can provide data regarding leadership development for physicians. The study demonstrated that there is a strong association between physician leadership and patient outcomes and that organizations play a primary role in supporting the development of physician leaders. Findings indicate that a physician's relationship with their patient and their capacity for innovation can be extended as catalytic behaviours in a complex system. The findings also identified limiting factors that impact physicians who choose to lead, such as reimbursement models that do not place value on leadership and medical education that provides minimal opportunity for leadership skill development. Practical Implications This research provides practical

  7. Culture And Leadership: The Case Of Romania

    Directory of Open Access Journals (Sweden)

    Raluca-Elena Hurduzeu


    Full Text Available Globalization and internationalization lead to the development of a general image of good and effective leadership which influence the local leadership styles and the behavior of leaders. The latter must overcome the conflict between the desire to implement corporate standards which are internationally valid and the need to act locally in terms of organizational culture, business environment and leadership style. The knowledge of the national peculiarities and traditions, the understanding of their heritage and background, coming to grips with them are key-success factors for international co-operations and/or joint-ventures in today’s competitive world. The aim of this paper is to explore the connection between the organizational culture and the leadership style and aims to develop a better understanding of the Romanian leadership. It also provides important information and ideas on the leadership styles practiced in the companies within Romania. The study presents the research findings on the Romanian leadership style and connects it to the political, economic and cultural influences. As far as Romania is concerned, although the variations in the cultural configurations are of a great diversity and complexity, we may, however, identify two distinct types of organizational culture, supporting the hypothesis that these two categories are the extremes of a continuum with a wide variety of expression: a culture of ‘bureaucratic’ type, typical for: state-owned companies, former state firms in the post-privatisation period and the culture of ‘entrepreneurial’ type, in the process of formation, typical for the private companies formed after 1989. The most important problems that appear in the case of the multinational companies refer to the compensation values, sacred and taboo, the management of the gradual conflicts, etnocentrism, affiliation, faulty conciliation and naive realism. The leaders must learn to analyze the cultural

  8. Self-determining medical leadership needs of occupational health physicians. (United States)

    Giri, Prosenjit; Aylott, Jill; Kilner, Karen


    Purpose The purpose of this study was to explore which factors motivate doctors to engage in leadership roles and to frame an inquiry of self-assessment within Self-Determination Theory (SDT) to identify the extent to which a group of occupational health physicians (OHPs) was able to self-determine their leadership needs, using a National Health Service (NHS) England competency approach promoted by the NHS England Leadership Academy as a self-assessment leadership diagnostic. Medical leadership is seen as crucial to the transformation of health-care services, yet leadership programmes are often designed with a top-down and centrally commissioned "one-size-fits-all" approach. In the UK, the Smith Review (2015) concluded that more decentralised and locally designed leadership development programmes were needed to meet the health-care challenges of the future. However, there is an absence of empirical research to inform the design of effective strategies that will engage and motivate doctors to take up leadership roles, while at the same time, health-care organisations continue to develop formal leadership roles as a way to secure medical leadership engagement. The problem is further compounded by a lack of validated leadership qualities assessment instruments which support researching this problem. Design/Methodology/approach The analysis draws on a sample of about 25 per cent of the total population size of the Faculty of Occupational Medicine ( n = 1,000). The questionnaire used was the Leadership Qualities Framework tool as a form of online self-assessment ( NHS Leadership Academy, 2012 ). The data were analysed using descriptive statistics and simple inferential methods. Findings OHPs are open about reporting their leadership strengths and leadership development needs and recognise leadership learning as an ongoing development need regardless of their level of personal competence. This study found that the single most important factor to affect a doctor

  11. Vorticity Transport on a Flexible Wing in Stall Flutter (United States)

    Akkala, James; Buchholz, James; Farnsworth, John; McLaughlin, Thomas


    The circulation budget within dynamic stall vortices was investigated on a flexible NACA 0018 wing model of aspect ratio 6 undergoing stall flutter. The wing had an initial angle of attack of 6 degrees, Reynolds number of 1 . 5 ×105 and large-amplitude, primarily torsional, limit cycle oscillations were observed at a reduced frequency of k = πfc / U = 0 . 1 . Phase-locked stereo PIV measurements were obtained at multiple chordwise planes around the 62.5% and 75% spanwise locations to characterize the flow field within thin volumetric regions over the suction surface. Transient surface pressure measurements were used to estimate boundary vorticity flux. Recent analyses on plunging and rotating wings indicates that the magnitude of the pressure-gradient-driven boundary flux of secondary vorticity is a significant fraction of the magnitude of the convective flux from the separated leading-edge shear layer, suggesting that the secondary vorticity plays a significant role in regulating the strength of the primary vortex. This phenomenon is examined in the present case, and the physical mechanisms governing the growth and evolution of the dynamic stall vortices are explored. This work was supported by the Air Force Office of Scientific Research through the Flow Interactions and Control Program monitored by Dr. Douglas Smith, and through the 2014 AFOSR/ASEE Summer Faculty Fellowship Program (JA and JB).

  12. An Empirical Study of Leadership Style of Middle Managers in Taiwan’s University Libraries

    Directory of Open Access Journals (Sweden)

    Chen Su-may Sheih


    Full Text Available Few studies have addressed the topic on leadership within the field of librarianship. With a hope to add to the narrative literature of the leadership, the researcher employed literature review and analysis, questionnaires, and statistics analysis, to explore the leadership style of middle managers in the university libraries in Taiwan area. 343 university librarians and 85 department heads participated in this survey. The survey data indicates that there is a discrepancy between middle managers’ self expressed leadership behavior profiles and those perceived by subordinate librarians. And some subordinate librarians’ demographics may affect their perceptions of leadership behavior demonstrated by department heads. [Article content in Chinese

  13. Complexity leadership: a healthcare imperative. (United States)

    Weberg, Dan


    The healthcare system is plagued with increasing cost and poor quality outcomes. A major contributing factor for these issues is that outdated leadership practices, such as leader-centricity, linear thinking, and poor readiness for innovation, are being used in healthcare organizations. Complexity leadership theory provides a new framework with which healthcare leaders may practice leadership. Complexity leadership theory conceptualizes leadership as a continual process that stems from collaboration, complex systems thinking, and innovation mindsets. Compared to transactional and transformational leadership concepts, complexity leadership practices hold promise to improve cost and quality in health care. © 2012 Wiley Periodicals, Inc.

    Frimann, Søren; Hersted, Lone


    This article analyzes the construction of leadership identities through stories found in four narrative interviews from a qualitative study and leadership development project based on social constructionism and action learning. We argue that leadership development and the construction of leadership...... that the concept of coauthoring is useful in developing leadership and leadership identities through reflexive dialogs and emerging stories....... narrative interviews about their challenges as leaders? In addition, how do these discursive constructions restrict or enable new perspectives, other voices, and the possibilities for learning and change? Our analysis identified traces of both modern and postmodern leadership discourses. We suggest...

  15. Leadership styles of nurse managers in a multinational environment. (United States)

    Suliman, Wafika A


    This is a descriptive study conducted at a multinational working environment, where 1500 nurses representing 52 nationalities are employed. The study aimed at exploring the predominant leadership style of nurse managers through self-evaluation and staff nurses' evaluation and the impact of working in a multinational environment on their intention to stay or quit. The value lies in its focus on leadership styles in an environment where national diversity among managers, staff, and patients is very challenging. The study included 31 nurse managers and 118 staff nurses using Bass and Avolio's (1995) Multifactor Leadership Questionnaire. The results showed that nurse managers and staff nurses reported transformational leadership as predominant with significant difference in favor of nurse managers. Participants' nationality and intention to stay or quit affected their perception of transformational leadership as a predominant style. The implications highlight the need for senior nursing management to set effective retention strategies for transformational nurse managers who work at multinational environments.

  16. Simulations in nursing practice: toward authentic leadership. (United States)

    Shapira-Lishchinsky, Orly


    Aim  This study explores nurses' ethical decision-making in team simulations in order to identify the benefits of these simulations for authentic leadership. Background  While previous studies have indicated that team simulations may improve ethics in the workplace by reducing the number of errors, those studies focused mainly on clinical aspects and not on nurses' ethical experiences or on the benefits of authentic leadership. Methods  Fifty nurses from 10 health institutions in central Israel participated in the study. Data about nurses' ethical experiences were collected from 10 teams. Qualitative data analysis based on Grounded Theory was applied, using the atlas.ti 5.0 software package. Findings  Simulation findings suggest four main benefits that reflect the underlying components of authentic leadership: self-awareness, relational transparency, balanced information processing and internalized moral perspective. Conclusions  Team-based simulation as a training tool may lead to authentic leadership among nurses. Implications for nursing management  Nursing management should incorporate team simulations into nursing practice to help resolve power conflicts and to develop authentic leadership in nursing. Consequently, errors will decrease, patients' safety will increase and optimal treatment will be provided. © 2012 John Wiley & Sons Ltd.

    Full Text Available In this paper we analyzed the cirumstances of every day life which requires the need to adapt the leadership style. Leadership needs a lot of abilities and skills, including the capability to communicate. The paper deals with leader’s need of changing the style of leading as organizational circumstances change. The process is efficient only when the leaders and the followers have the right climate. The importance of this process is reflected in the productivity of the organization. As the economic climate changes the leadership style needs to be changed and also the style of communication throughout the leader coaches, coordinates, evaluates and supervises. Leadership is about organizing a group of people to achieve a goal. The leader may or may not have any formal authority. Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. This paper describes the styles of leadership which the leaders must use and switch when is needed in comparison with what leadership is about.

  18. Hovering hummingbird wing aerodynamics during the annual cycle. II. Implications of wing feather moult (United States)

    Sapir, Nir; Elimelech, Yossef


    Birds usually moult their feathers in a particular sequence which may incur aerodynamic, physiological and behavioural implications. Among birds, hummingbirds are unique species in their sustained hovering flight. Because hummingbirds frequently hover-feed, they must maintain sufficiently high flight capacities even when moulting their flight feathers. A hummingbird wing consists of 10 primary flight feathers whose absence during moult may strongly affect wing performance. Using dynamic similarity rules, we compared time-accurate aerodynamic loads and flow field measurements over several wing geometries that follow the natural feather moult sequence of Calypte anna, a common hummingbird species in western North America. Our results suggest a drop of more than 20% in lift production during the early stages of the moult sequence in which mid-wing flight feathers are moulted. We also found that the wing's ability to generate lift strongly depended on the morphological integrity of the outer primaries and leading-edge. These findings may explain the evolution of wing morphology and moult attributes. Specifically, the high overlap between adjacent wing feathers, especially at the wing tip, and the slow sequential replacement of the wing feathers result in a relatively small reduction in wing surface area during moult with limited aerodynamic implications. We present power and efficiency analyses for hover flight during moult under several plausible scenarios, suggesting that body mass reduction could be a compensatory mechanism that preserves the energetic costs of hover flight.

  19. Contribution of a winged phlebotomy device design to blood splatter. (United States)

    Haiduven, Donna J; McGuire-Wolfe, Christine; Applegarth, Shawn P


    Despite a proliferation of phlebotomy devices with engineered sharps injury protection (ESIP), the impact of various winged device designs on blood splatter occurring during venipuncture procedures has not been explored. To evaluate the potential for blood splatter of 6 designs of winged phlebotomy devices. A laboratory-based device evaluation without human subjects, using a simulated patient venous system. We evaluated 18 winged phlebotomy devices of 6 device designs by Terumo, BD Vacutainer (2 designs), Greiner, Smith Medical, and Kendall (designated A-F, respectively). Scientific filters were positioned around the devices and weighed before and after venipuncture was performed. Visible blood on filters, exam gloves, and devices and measurable blood splatter were the primary units of analysis. The percentages of devices and gloves with visible blood on them and filters with measurable blood splatter ranged from 0% to 20%. There was a statistically significant association between device design and visible blood on devices ([Formula: see text]) and between device design and filters with measurable blood splatter ([Formula: see text]), but not between device design and visible blood on gloves. A wide range of associations were demonstrated between device design and visible blood on gloves or devices and incidence of blood splatter. The results of this evaluation suggest that winged phlebotomy devices with ESIP may produce blood splatter during venipuncture. Reinforcing the importance of eye protection and developing a methodology to assess ocular exposure to blood splatter are major implications for healthcare personnel who use these devices. Future studies should focus on evaluating different designs of intravascular devices (intravenous catheters, other phlebotomy devices) for blood splatter.

  20. DAST in Flight just after Structural Failure of Right Wing (United States)


    conducting in-flight experiments from a remote ground site. DAST explored the technology required to build wing structures with less than normal stiffness. This was done because stiffness requires structural weight but ensures freedom from flutter-an uncontrolled, divergent oscillation of the structure, driven by aerodynamic forces and resulting in structural failure. The program used refined theoretical tools to predict at what speed flutter would occur. It then designed a high-response control system to counteract the motion and permit a much lighter wing structure. The wing had, in effect, 'electronic stiffness.' Flight research with this concept was extremely hazardous because an error in either the flutter prediction or control system implementation would result in wing structural failure and the loss of the vehicle. Because of this, flight demonstration of a sub-scale vehicle made sense from the standpoint of both safety and cost. The program anticipated structural failure during the course of the flight research. The Firebee II was a supersonic drone selected as the DAST testbed because its wing could be easily replaced, it used only tail-mounted control surfaces, and it was available as surplus from the U. S. Air Force. It was capable of 5-g turns (that is, turns producing acceleration equal to 5 times that of gravity). Langley outfitted a drone with an aeroelastic, supercritical research wing suitable for a Mach 0.98 cruise transport with a predicted flutter speed of Mach 0.95 at an altitude of 25,000 feet. Dryden and Langley, in conjunction with Boeing, designed and fabricated a digital flutter suppression system (FSS). Dryden developed an RPRV (remotely piloted research vehicle) flight control system; integrated the wing, FSS, and vehicle systems; and conducted the flight program. In addition to a digital flight control system and aeroelastic wings, each DAST drone had research equipment mounted in its nose and a mid-air retrieval system in its tail. The drones

  9. Semi-automated quantitative Drosophila wings measurements. (United States)

    Loh, Sheng Yang Michael; Ogawa, Yoshitaka; Kawana, Sara; Tamura, Koichiro; Lee, Hwee Kuan


    Drosophila melanogaster is an important organism used in many fields of biological research such as genetics and developmental biology. Drosophila wings have been widely used to study the genetics of development, morphometrics and evolution. Therefore there is much interest in quantifying wing structures of Drosophila. Advancement in technology has increased the ease in which images of Drosophila can be acquired. However such studies have been limited by the slow and tedious process of acquiring phenotypic data. We have developed a system that automatically detects and measures key points and vein segments on a Drosophila wing. Key points are detected by performing image transformations and template matching on Drosophila wing images while vein segments are detected using an Active Contour algorithm. The accuracy of our key point detection was compared against key point annotations of users. We also performed key point detection using different training data sets of Drosophila wing images. We compared our software with an existing automated image analysis system for Drosophila wings and showed that our system performs better than the state of the art. Vein segments were manually measured and compared against the measurements obtained from our system. Our system was able to detect specific key points and vein segments from Drosophila wing images with high accuracy.

    Henninger, Michael; Barth, Christina


    Medical leadership requires specific communication skills in order to meet professional demands. Communicative behaviour is usually highly automated and not necessarily conscious. Managerial communication competes against elaborated but not role-specific behaviour patterns, especially in critical situations. Accordingly, competent medical leadership requires the awareness of individual communication habits as well as the knowledge and ability to use conversation techniques suitable for a specific situational context. The training of leadership-related communication techniques requires the de-automation of existing skills and a problem-oriented construction and re-automation of new communication techniques.

  15. The influence of trait-emotional intelligence on authentic leadership

    Directory of Open Access Journals (Sweden)

    Martina Kotzé


    Full Text Available Orientation: Authentic leadership is a relatively new construct that has recently gained increasing attention resulting from challenges faced by organisations relating to ethical meltdowns, corruption and fraud. Research purpose: This study seeks to explore the relationship between components of emotional intelligence and authentic leadership. Motivation for the study: Several authors called for more empirical investigations into the antecedents of authentic leadership. Despite the important role that emotions play in leadership, empirical studies were lacking about the influence of different components of emotional intelligence to authentic leadership. Research design, approach and method: Data were collected, using questionnaires obtained from 341 full-time employed applicants to MBA and leadership programmes in a South African Business School. Relationships between variables were analysed, using Pearson product-moment correlations and stepwise multiple regression. Main findings: The results indicated that emotional intelligence has positive statistically significant associations with authentic leadership. Specifically, those who scored high on all the emotional intelligence components also scored high on authentic leadership. In addition, the emotional intelligence component of empathy was a statistically significant predictor of authentic leadership. Practical/managerial implications: Initial findings suggest the potential value of recognising and developing the emotional intelligence of leaders to enable them to lead their organisations authentically to desired, successful outcomes. As empathy has been shown to be the most important emotional intelligence predictor of authentic leadership, leaders need to understand when subordinates perceive a leader as displaying empathic emotion. Contribution: This study contributes to the literature and empirical research on the antecedents of authentic leadership.

  17. Novel Control Effectors for Truss Braced Wing (United States)

    White, Edward V.; Kapania, Rakesh K.; Joshi, Shiv


    At cruise flight conditions very high aspect ratio/low sweep truss braced wings (TBW) may be subject to design requirements that distinguish them from more highly swept cantilevered wings. High aspect ratio, short chord length and relative thinness of the airfoil sections all contribute to relatively low wing torsional stiffness. This may lead to aeroelastic issues such as aileron reversal and low flutter margins. In order to counteract these issues, high aspect ratio/low sweep wings may need to carry additional high speed control effectors to operate when outboard ailerons are in reversal and/or must carry additional structural weight to enhance torsional stiffness. The novel control effector evaluated in this study is a variable sweep raked wing tip with an aileron control surface. Forward sweep of the tip allows the aileron to align closely with the torsional axis of the wing and operate in a conventional fashion. Aft sweep of the tip creates a large moment arm from the aileron to the wing torsional axis greatly enhancing aileron reversal. The novelty comes from using this enhanced and controllable aileron reversal effect to provide roll control authority by acting as a servo tab and providing roll control through intentional twist of the wing. In this case the reduced torsional stiffness of the wing becomes an advantage to be exploited. The study results show that the novel control effector concept does provide roll control as described, but only for a restricted class of TBW aircraft configurations. For the configuration studied (long range, dual aisle, Mach 0.85 cruise) the novel control effector provides significant benefits including up to 12% reduction in fuel burn.

  18. Consultant radiographer leadership - A discussion

    International Nuclear Information System (INIS)

    Hogg, Peter; Hogg, Dianne; Henwood, Suzanne


    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

  19. Aerodynamic performance of two-dimensional, chordwise flexible flapping wings at fruit fly scale in hover flight. (United States)

    Sridhar, Madhu; Kang, Chang-kwon


    Fruit flies have flexible wings that deform during flight. To explore the fluid-structure interaction of flexible flapping wings at fruit fly scale, we use a well-validated Navier-Stokes equation solver, fully-coupled with a structural dynamics solver. Effects of chordwise flexibility on a two dimensional hovering wing is studied. Resulting wing rotation is purely passive, due to the dynamic balance between aerodynamic loading, elastic restoring force, and inertial force of the wing. Hover flight is considered at a Reynolds number of Re = 100, equivalent to that of fruit flies. The thickness and density of the wing also corresponds to a fruit fly wing. The wing stiffness and motion amplitude are varied to assess their influences on the resulting aerodynamic performance and structural response. Highest lift coefficient of 3.3 was obtained at the lowest-amplitude, highest-frequency motion (reduced frequency of 3.0) at the lowest stiffness (frequency ratio of 0.7) wing within the range of the current study, although the corresponding power required was also the highest. Optimal efficiency was achieved for a lower reduced frequency of 0.3 and frequency ratio 0.35. Compared to the water tunnel scale with water as the surrounding fluid instead of air, the resulting vortex dynamics and aerodynamic performance remained similar for the optimal efficiency motion, while the structural response varied significantly. Despite these differences, the time-averaged lift scaled with the dimensionless shape deformation parameter γ. Moreover, the wing kinematics that resulted in the optimal efficiency motion was closely aligned to the fruit fly measurements, suggesting that fruit fly flight aims to conserve energy, rather than to generate large forces.
