Leadership: Wisdom in Action

The purpose of this paper is to reveal how the thinking of leadership is always in ‘play’ enacting the wisdom of practice. The ‘know how’ of leadership theory (techne) tends to assume that a plan, or a set of skills, can accomplish whatever one sets out to achieve. However, the nature of human and contextual encounter instead draws one into a dynamic relationship where all is in-play. To lead is to recognise the impact and primacy of play and to respond accordingly. For this research study, experienced leaders were interviewed and data was analysed drawing on the philosophical notions of Heidegger and Gadamer, using a phenomenological methodology. The findings indicate that ‘know how’ is not sufficient. Strong leadership requires wisdom that is enacted in the moment. In addition, ‘who’ the leader is matters, for in the dynamic of play leaders can only draw on their own integrity. Being attuned to the play  also matters, for discerning mood, possibilities and threats prompt the leader’s next move. Leadership that enables individuals to play with wisdom, foresight and sound judgement can only be learnt through experience. The implications are that emerging leaders need to be exposed to the play of leadership and to be mentored by experienced leaders who can share their wisdom.Indo-Pacific Journal of Phenomenology, Volume 11, Edition 1 May 2011, 47-5

Therapists’ Experience of Working with Suicidal Clients

This paper is based on a study of therapists’ experiences of working with suicidal clients. Using a hermeneutic-phenomenological methodology informed by Heidegger, the study provides an understanding of the meaning of therapists’ experiences from their perspective as mental health professionals in New Zealand. In this regard, the findings of the study identified three themes: Therapists’ reaction of shock upon learning of the suicide of their client; Therapists’ experience of assessing suicidal clients as a burden; and finally, Therapists’ professional and personal crises as a result of their experiences and struggling to come to terms with events. The study sheds light on how the experiences of therapists whose clients have committed suicide can be understood. The findings show how mainstream prevention and intervention strategies result from the misrepresentation and misinterpretation of our traditional way of knowing what it means to be human. When therapists discover that phenomena are not necessarily what they appear to be, they feel unsettled and confused about their responsibilities and what it means to live and die as a human being. The study reveals that therapists experience a profound legacy of guilt, doubt and fear when a client commits suicide. Finally, the study proposes that the time has come for the profession to care for its own in order to allow therapist, in turn to care for (and about) the vulnerable other.Indo-Pacific Journal of Phenomenology, Volume 11, Edition 1, May 2011, 25-3

From Place to Space: A Heideggerian Analysis

In this paper, we pay attention to the impact on staff of what was a new place, Ko Awatea, within a large New Zealand hospital. The place became a space from within which a particular mood arose. This paper seeks to capture that mood and its impact. Using a Heideggerian hermeneutic approach, the study reported on drew on data from interviews with 20 staff. Philosophical notions about the nature and mood of place/space are explored. As staff claimed this space, the mood that emerged was of liveliness, buzz and comfort. It became a space where people wanted to be, where they met others, where  conversations unfolded, where thinking happened in new ways. Staff places tend to be sacrificed or poorly resourced in resource-tight environments. We argue that creating a space that feels home-like, where staff come, linger and engage in community is a priority for generating the mood and thinking of an organization. Such spaces do not happen by chance; it takes forethought and intentionality. The gift of such space is the thinking that is sparked and grown

Professional Doctorates: Grasping A New Way

It is one thing to write a curriculum for a professional doctorate with a graduate profile that talks of practice-change and leadership development. Our experience of initiating the Doctor of Health Science in 2002 was that it was all too easy to fall back on the PhD mindset. It took inspiration from the literature, and pioneering candidates, to show us how this programme could be distinctively different from a PhD. We tell our story to reveal both challenges and possibilities. We see that all our candidates have a focus on bringing change to practice. Some do this through research ‘on’ practice, others by research ‘in’ practice, and then there are those caught up in the research/practice nexus. We believe a professional doctorate programme has potential to significantly grow the candidate into a leader of practice-change

Water Quality Model for Evaluation of Nonpoint Source Impacts of Rice Field Runoff.

Water quality impairment in many water bodies in the state of Louisiana is attributed to agricultural nonpoint sources of pollution. Many of these use-impaired streams have also been hydromodified to facilitate agricultural development, deepening and straightening the channels to form stretch lakes . This dissertation evaluated the unique, and previously uncharacterized and unquantified ricefield loadings and their impacts on these dystrophic waterbodies in order to provide the Louisiana Department of Environmental Quality (LDEQ) with assessments of stream impacts from implementing altered cropping practices known as best management practices (BMPs). In order to produce an assessment of rice BMPs, this dissertation developed several unique tools: (1) Development of the LA reaeration equation and measurement of dispersion. Dispersive mixing was found to be significant in these low velocity, hydromodified streams, requiring the use of a dynamic model and necessitating the development of measurement techniques, and the development of empirical equations so that reaeration may be tied to the depth and velocity profiles found in the stretch lakes . (2) Determination of SOD and mechanism of deoxygenation. The stream was found to have a dissolved oxygen (DO) deficit that is sediment oxygen demand (SOD)-driven and the bottom anoxia was shown to be heavily impacted from agricultural nutrients, sediments and organic material. The SOD determined during calibration far exceeded those found in the literature; values of 4.0 g-O2/m2/day in the rice receiving streams were not uncommon. (3) Characterization and quantification of ricefield discharge BMP and sediment flux pollutant loads. Oxygen-demanding pollutant loads (carbonaceous biochemical oxygen demand, CBOD and nitrogenous, NBOD) were quantified for headwater, ricefield BUT discharges and resuspended sediment fluxes throughout an annual cycle. CBOD in the sediment flux was also estimated to be as great as 4.0 g-O2/m2/day during critical low-flow. (4) Development of a conversion algorithm from TOC to CBODu. Characterizing the sediment fluxes and rice discharge constituents required the use of long-term BOD data that is rarely available in datasets. A conversion algorithm from total organic carbon (TOC) was, thus, developed for use as a surrogate for ultimate CBOD (CBODu)

Open, trusting relationships underpin safety in rural maternity a hermeneutic phenomenology study.

Background: There are interwoven personal, professional and organisational relationships to be navigated in maternity in all regions. In rural regions relationships are integral to safe maternity care. Yet there is a paucity of research on how relationships influence safety and nurture satisfying experiences for rural maternity care providers and mothers and families in these regions. This paper draws attention to how these relationships matter. Methods: This research is informed by hermeneutic phenomenology drawing on Heidegger and Gadamer. Thirteen participants were recruited via purposeful sampling and asked to share their experiences of rural maternity care in recorded unstructured in-depth interviews. Participants were women and health care providers living and working in rural regions. Recordings were transcribed and data interpretively analysed until a plausible and trustworthy thematic pattern emerged. Results: Throughout the data the relational nature of rural living surfaced as an interweaving tapestry of connectivity. Relationships in rural maternity are revealed in myriad ways: for some optimal relationships, for others feeling isolated, living with discord and professional disharmony. Professional misunderstandings undermine relationships. Rural maternity can become unsustainable and unsettling when relationships break down leading to unsafeness. Conclusions: This study reveals how relationships are an important and vital aspect to the lived-experience of rural maternity care. Relationships are founded on mutual understanding and attuned to trust matter. These relationships are forged over time and keep childbirth safe and enable maternity care providers to work sustainably. Yet hidden unspoken pre-understandings of individuals and groups build tension in relationships leading to discord. Trust builds healthy rural communities of practice within which everyone can flourish, feel accepted, supported and safe. This is facilitated by collaborative learning activities and open respectful communication founded on what matters most (safe positive childbirth) whilst appreciating and acknowledging professional and personal differences

Midwifing the notion of a 'good' birth: a philosophical analysis.

Objective: to ponder afresh what makes a good birth experience in a listening manner. Design: a hermeneutic approach that first explores the nature of how to listen to a story that is already familiar to us and then draws on Heidegger's notion of the fourfold to seek to capture how the components of a'good birth' come together within experience. Setting: primary birthing centre, New Zealand Participants: the focus of this paper is the story of one participant. It was her second birth; her first birth involved a lot of medical intervention. She had planned to travel one hour to the tertiary birthing unit but in labour chose to stay at the Birth Centre. Her story seems to portray a 'very good birth'. Findings: in talking of birth, the nature of a research approach is commonly to focus on one aspect: the place, the care givers, or the mode of care. In contrast, we took on the challenge of first listening to all that was involved in one woman's story. We came to see that what made her experience 'good' was'everything' gathered together in a coherent and supportive oneness. Heidegger's notion of the fourfold helped reveal that one cannot talk about one thing without at the same time talking about all the other things as well. Confidence was the thread that held the story together. Key conclusions: there is value in putting aside the fragmented approach of explicating birth to recognise the coming together of place, care, situation, and the mystery beyond explanation. Women grow a confidence in place when peers and community encourage the choice based on their own experience. Confidence of caregiver comes in relationship. Feeling confident within 'self' is part of the mystery. When confidence in the different dimensions holds together, birth is 'good'. Implications or practice: one cannot simply build a new birthing unit and assume it will offer a good experience of birth. Experience is about so much more. Being mindful of the dimensions of confidence that need to be built up and sheltered is a quest for wise leaders. Protecting the pockets where we know 'good birth' already flourishes is essential

Coordinated regulation of AP2 uncoating from clathrin-coated vesicles by rab5 and hRME-6

Here we investigate the role of rab5 and its cognate exchange factors rabex-5 and hRME-6 in the regulation of AP2 uncoating from endocytic clathrin-coated vesicles (CCVs). In vitro, we show that the rate of AP2 uncoating from CCVs is dependent on the level of functional rab5. In vivo, overexpression of dominant-negative rab5S34N, or small interfering RNA (siRNA)–mediated depletion of hRME-6, but not rabex-5, resulted in increased steady-state levels of AP2 associated with endocytic vesicles, which is consistent with reduced uncoating efficiency. hRME-6 guanine nucleotide exchange factor activity requires hRME-6 binding to α-adaptin ear, which displaces the ear-associated μ2 kinase AAK1. siRNA-mediated depletion of hRME-6 increases phospho-μ2 levels, and expression of a phosphomimetic μ2 mutant increases levels of endocytic vesicle-associated AP2. Depletion of hRME-6 or rab5S35N expression also increases the levels of phosphoinositide 4,5-bisphosphate (PtdIns(4,5)P2) associated with endocytic vesicles. These data are consistent with a model in which hRME-6 and rab5 regulate AP2 uncoating in vivo by coordinately regulating μ2 dephosphorylation and PtdIns(4,5)P2 levels in CCVs

The Role of Dynamin and Its Binding Partners in Coated Pit Invagination and Scission

Plasma membrane clathrin-coated vesicles form after the directed assembly of clathrin and the adaptor complex, AP2, from the cytosol onto the membrane. In addition to these structural components, several other proteins have been implicated in clathrin-coated vesicle formation. These include the large molecular weight GTPase, dynamin, and several Src homology 3 (SH3) domain–containing proteins which bind to dynamin via interactions with its COOH-terminal proline/arginine-rich domain (PRD). To understand the mechanism of coated vesicle formation, it is essential to determine the hierarchy by which individual components are targeted to and act in coated pit assembly, invagination, and scission

Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity

Creating a robust synthetic surface that repels various liquids would have broad technological implications for areas ranging from biomedical devices and fuel transport to architecture but has proved extremely challenging. Inspirations from natural nonwetting structures particularly the leaves of the lotus, have led to the development of liquid-repellent microtextured surfaces that rely on the formation of a stable air–liquid interface. Despite over a decade of intense research, these surfaces are, however, still plagued with problems that restrict their practical applications: limited oleophobicity with high contact angle hysteresis, failure under pressure and upon physical damage inability to self-heal and high production cost. To address these challenges, here we report a strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency. Our approach—inspired by Nepenthes pitcher plants—is conceptually different from the lotus effect, because we use nano/microstructured substrates to lock in place the infused lubricating fluid. We define the requirements for which the lubricant forms a stable, defect-free and inert ‘slippery’ interface. This surface outperforms its natural counterparts and state-of-the-art synthetic liquid-repellent surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low contact angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1–1 s), resist ice adhesion, and function at high pressures (up to about 680 atm). We show that these properties are insensitive to the precise geometry of the underlying substrate, making our approach applicable to various inexpensive, low-surface-energy structured materials (such as porous Teflon membrane). We envision that these slippery surfaces will be useful in fluid handling and transportation, optical sensing, medicine, and as self-cleaning and anti-fouling materials operating in extreme environments.Engineering and Applied Science
