Why not give up? A study on the role of resourcefulness in goal pursuit
Past research suggests that taking a process oriented approach, setting clear and concrete goals, and using both conscious planning and proactive coping are the best methods to be successful with goal pursuit. Also the literature has found that individuals scoring higher in general resourcefulness tend to be more successful at achieving goals than their less resourceful counterparts. My thesis looked at these goal pursuit behaviours under the lens of resourcefulness using a mixed methods approach. After completing Rosenbaum’s self-control scale (1980) assessing general resourcefulness, participants took part in a semi-structured interview asking them about a recent goal they had set and how they dealt with interfering obstacles. The hope was hearing differences about how highly and less resourceful people discuss their goals and setbacks would give a deeper understanding about the characteristics of success. The themes emerging from the interviews were: blame and excuses versus understanding and growth, internal versus external factors, living in the moment versus conscious planning and magical versus realistic thinking. In contrast to low-scoring participants, highly resourceful individuals grew from their setbacks, were internally driven, consciously planned, and thought realistically about their goals. Less resourceful individual, on the other hand blamed outside factors and made excuses, were only motivated externally, didn’t plan out their goals and believed their goals would just magically materialize over time. My discussion focuses on the ability to train lower resourceful individuals over longer interventions, and the applications of understanding and using resourcefulness as a lens in future studies.

Analysis and reactions of aqueous selenide and other reduced inorganic selenium compounds under anoxic conditions
Selenide is cited as a geochemically important selenium (Se) species, but it is unknown whether selenide is a stable aqueous ion in natural waters. The feasibility of using anoxic anion exchange chromatography (AEC) coupled to dynamic reaction cell-inductively coupled plasma-mass spectrometry to separate aqueous selenide was investigated with the goal of quantifying this anion to determine its importance in reducing waters. It was possible to qualitatively identify selenide using AEC, but much of the aqueous selenide oxidises to Se0 faster than the separation procedure could be completed. AEC analyses of solutions containing polyselenides produced peaks for unidentified Se compounds, which have been assigned tentative structures Se2O22-, Se2O32-, and Se2O62- based on close matches in retention time to stable S compounds. The results of this work show that aqueous selenide can be qualitatively observed in synthetic solutions using AEC, but it is unknown whether these conditions are relevant to natural waters.
