title: Time-scale dependence in numerical simulations: Assessment of physical, chemical, and biological predictions in a stratified lake at temporal scales of hours to months

authors: Kara, Emily L.

subjects: ecosystem modelling

abstract: We evaluated the predictive ability of a one-dimensional coupled hydrodynamic-biogeochemical model across multiple temporal scales using wavelet analysis and traditional goodness-of-fit metrics. High-frequency in situ automated sensor data and long-term manual observational data from Lake Mendota, Wisconsin, USA, were used to parameterize, calibrate, and evaluate model predictions. We focused specifically on short-term predictions of temperature, dissolved oxygen, and phytoplankton biomass over one season. Traditional goodness-of-fit metrics indicated more accurate prediction of physics than chemical or biological variables in the time domain. This was confirmed by wavelet analysis in both the time and frequency domains. For temperature, predicted and observed global wavelet spectra were closely related, while observed dissolved oxygen and chlorophyll fluorescence spectral characteristics were not reproduced by the model for key time scales, indicating that processes not modeled may be important drivers of the observed signal. Although the magnitude and timing of physical and biological changes were simulated adequately at the seasonal time scale through calibration, time scale-specific dynamics, for example short-term cycles, were difficult to reproduce, and were relatively insensitive to the effects of varying parameters. The use of wavelet analysis is novel to aquatic ecosystem modeling, is complementary to traditional goodness-of-fit metrics, and allows for assessment of variability at specific temporal scales. In this way, the effect of processes operating at distinct temporal scales can be isolated and better understood, both in situ and in silico. Wavelet transforms are particularly well suited for assessment of temporal and spatial heterogeneity when coupled to high-frequency data from automated in situ or remote sensing platforms.

title: The imposter phenomenon : an exploration of the need to please

authors: Wells, Debra

subjects: Women Psychology

abstract: The Imposter Phenomenon is an internal sense of intellectual phoniness that results in those who experience it, discounting their abilities by attributing success to such things as luck or charm. 

The topic of this thesis is "The Imposter Phenomenon: An Exploration of the Need to Please" Bussotti (1990) noted in her doctoral thesis that she unexpectedly found a strong association between the need to please and the Imposter Phenomenon and that this warranted further study. This thesis considers the roles Imposters received within their families as children and the impact of the subsequent need to please within the family unit, on the personal development of the Imposter Phenomenon. It however takes the dynamic of the need to please beyond the individual and places it into the wider framework of gender role socialisation.

The theory that I postulate is that the way in which one pleases another is gendered in its understanding and outworking. The seven women who participated in this research were all from homes where traditional male and female roles were modeled. They learnt that to please others meant to behave as a traditionally defined female. Within this definition there was little room for more masculine traits to be integrated within their self-concept. When later in their lives they experienced academic success they attributed this not to their more masculised behaviours such as assertiveness and competitiveness but rather to the more neutral attributions of luck, or faking it. They said they felt like Imposters waiting to be discovered. I have proposed that this duality be named the Margaret Thatcher/Mother Teresa Identity Enigma. 

A brief outline of the thesis chapters is now provided.

Chapter One: Provides a comprehensive literature review of the Imposter Phenomenon research. It covers a definition of the Imposter Phenomenon, why it is considered a problem, characteristics of the Imposter Phenomenon, family dynamics, longevity and maintenance of Imposter dynamics and therapy.

Chapter Two: Imposter Phenomenon - In Other Guises shows how the concept of the Imposter Phenomenon is in fact one of many explanations of the same thing, the fear of failure. It specifically looks at Fear of Failure, Self-Worth Protection Theory, and the Achilles Syndrome.

Chapter Three: Gender Role Development considers three broad theories of gender role development. These are Biological, Social, and Structural theories. It suggests that the social and structural theories are of most use when considering Imposter Dynamics because they recognise that women are shaped to a large extent by the society in which they grow up in.

Chapter Four: Methodology, begins by outlining the paradigm of lnterpretivism used in this research. It also covers procedure, recruitment, participants and instruments utilised. It also addresses limitations of this research.

Chapter Five: Findings presents the voices of the participants themselves in sections that weave together to show the impact of 'needing to please' others on their lives.

Chapter Six: Towards a Social Theory of the Imposter Phenomenon pulls all of the different threads together and suggests a new theory about the impact of the need to please on the development of the Imposter Phenomenon.

title: Promoting social and environmental justice to support Indigenous partnerships in urban ecosystem restoration

authors: Hall, Monique

subjects: Science & Technology

abstract: Urban ecological restoration typically employs western science approaches to restore degraded ecosystems. As yet, few restoration groups acknowledge the history of these degraded urban sites, despite connections, past and present, that root Indigenous Peoples (and others) in these lands. Here, we promote partnership with Indigenous communities from project inception and present two successful case studies from Aotearoa New Zealand. We specifically note that partnering and building relationships with Indigenous communities in restoration efforts require recognition of power inequalities and injustices. We consider success to include both restoration of ecological function and biodiversity and reconnection of all communities to urban ecosystems.
