Chemistry PhD Supervisors in Australia: A Study of the Relationship between their Conceptions of Doctoral Purpose and their Reported Educational Practices
Over the past 30 years, the literature on doctoral education has raised a number of debates about the research doctorate. This has included debates over its purpose and whether its graduates are well prepared to address the diverse and complex problems of todayâs workforce. However, scholarly literature on doctoral education in the academic discipline of chemistry is mostly non-existent. To address this research gap, I draw upon key concepts arising from the doctoral education literature such as doctoral purpose, practice, and evaluation to provide the necessary framing for this study. Based on this, I ask the following question: âWhat are the Positions of Chemistry PhD Supervisors in Australia in Relation to Contemporary Debates and Practices in Doctoral Education?â
This study adopts a qualitative research methodology in which 31 chemistry PhD supervisors in Australia were interviewed using the semi-structured interview method. Data were analysed thematically using both deductive analysis for pre-existing themes from the literature, and inductive analysis for emergent themes from the data. Three main themes characterised the analysis: supervisorsâ conceptions of doctoral purpose; their reported educational practices; and their reported methods of self-evaluation of supervisory success and graduate follow-up.
It was found that the reported practices for two groups of supervisors in the sample did not align with their conceptions of purpose. Instead, they showed a strong tendency to socialise their students into becoming custodians or âstewardsâ of the discipline, despite interviewees expressing conceptions of doctoral purpose that aligned with the development of graduates as knowledge workers equipped with the knowledge and skills for wider employment. For the other group, their conceptions of doctoral purpose did align with their reported educational practices of preparing âstewardsâ of the discipline, with their reported practices also tending towards setting up their students to become stewards. These issues were further compounded by supervisors not adequately following up with their graduates in terms of their career outcomes, despite them indicating that they considered graduate employment as one measure of supervisory success.
The main scholarly contribution this thesis makes is in initiating the scholarly debates and discussions about contemporary doctoral education within the discipline of chemistry. These debates and discussions are needed in order to not only critically reflect on the role and influence chemistry PhD supervisors have in the education of future chemistry PhD candidates, but also to critically contemplate the purpose and contribution of the chemistry doctorate in relation to the labour market and broader society. Practical implications arising will also be discussed
Chutes and Ladders: John Ashbery\u27s Poetics as Experience
Iâve always found it difficult to say just what I think is happening in John Ashberyâs poetry, even when I recognize that Iâve undergone something through the course of reading. With Ashbery, I find myself becoming conscious of how I construct meaning from language, and I understand this self-reflexivity as a âpoetics as experience.â Ashbery had read or at least been aware of the work of Ralph Waldo Emerson, William James, Gertrude Stein, and Wallace Stevensâall of which explore how consciousness manifests through language. I read these figures through American pragmatism, which views writing as an activity that follows perception as it moves through time. They have offered me a way to think about experience as it relates to reading and writing. Following in Ashberyâs tracks, I also read the French writer Raymond Roussel, whose work repositions reading from a hermeneutic act to a process driven by a curiosity towards the evasiveness of language. I do not intend to draw a causal relationship between these figures and Ashbery, but instead to highlight certain affinities in thinking about a âpoetics as experience.â
I begin in 1962 with Ashberyâs The Tennis Court Oath and work through his poems up until 1979, with As We Know. To contextualize my readings, I turn towards his contemporariesâ reviews along with the literary criticism that came in the following yearsâincluding Ashberyâs own interviews and biographical materials. I suggest that Ashberyâs poetics bears no secrets but offers an experience that happens as we know. Experiences occur simultaneously in Ashberyâs poetry through his transitions of attention as they reverberate through time. This has taught me how to listen, not only to the interplay of language, but also to myself as I read through his forking paths. I can say for certain that after reading Ashbery nothing has changed, except for the way I see myself in relation to the world

La peche continentale au lac de Songori (region du Gontougo; Nord-Est de la Cote D'Ivoire): Facteurs de production et niveau d'exploitation halieutique
RESUMELâĂ©tude de lâactivitĂ© de pĂȘche au lac de Songori (environ 1,5 kmÂČ) dans la rĂ©gion du Gontougo (Nord- Est de la CĂŽte dâIvoire) sâest dĂ©roulĂ©e de janvier 2013 Ă dĂ©cembre 2014. Elle montre que la pĂȘche est essentiellement pratiquĂ©e par des ivoiriens (100 %) avec une absence de pĂȘcheurs professionnels. Ces acteurs sont majoritairement des pĂȘcheurs-agriculteurs (80 %) et considĂšrent la pĂȘche comme une activitĂ© secondaire. Ils utilisent gĂ©nĂ©ralement les filets maillants (89,66 %) comme engins de pĂȘche. Des pirogues monoxyles (83,33 %) constituent les embarcations les plus couramment utilisĂ©es. Lâeffort de pĂȘche est autour de 2,7 pĂȘcheurs/kmÂČ. Les captures comprennent des espĂšces Ă©conomiquement importantes avec une prĂ©dominance de Oreochromis niloticus (68,10 % Ă 78,89 % de la biomasse annuelle). La production annuelle est comprise entre 13,33 et 13,51 t soit entre 88,9 et 90,1 kg/ha/an. Elle reste infĂ©rieure aux captures potentielles (entre 100 et 750 kg/ha/an) indiquĂ©es par la FAO pour ces plans dâeau ; ce qui montre quâil peut exister une marge pour augmenter la biomasse exploitĂ©e. Toutefois, le manque de professionnalisme des pĂȘcheurs, la vĂ©tustĂ© des engins de pĂȘche et lâoccupation du tiers (environ) du volume dâeau exploitable par des plantes aquatiques constituent une entrave majeure au dĂ©veloppement de cette activitĂ©.
ABSTRACTINLAND FISHING AT LAKE SONGORI (GONTOUGO REGION; NORTH-EAST OF THE IVORY COAST): FACTORS OF PRODUCTION AND LEVEL OF FISHING EXPLOITATIONThe study of fishing activity on Lake Songori (about 1.5 kmÂČ) in the area of Gontougo (north-east of Ivory Coast) took place from January 2013 to December 2014. It shows that fishing is mainly practiced by Ivorians (100%) with no professional fishermen. These actors are mainly fishermen-farmers (91.67%) and consider fishing as a secondary activity. They generally use gillnets (89.66%) as fishing gear. Monoxyls canoes (83.33%) are the most commonly used boats. The fishing effort is around 2.7 fishermen / kmÂČ. Catches include economically important species with a predominance of Oreochromis niloticus (68.10% to 78.89% of the annual biomass). The annual production is between 13,33 and 13,51 t or between 88.9 and 90.1 kg / ha / year. It remains lower the potential catches (between 100 and 750 kg / ha / year) reported by FAO for these water bodies; which shows that there may be a margin to increase the exploited biomass. However, the lack of professionalism of fishermen, the obsolescence of fishing gear and the occupation of about one-third of the volume of water exploitable by aquatic plants constitute a major obstacle to the development of this activity
Barreras y dificultades para la implementaciĂłn del sistema HACCP en empresas de alimentos de Lima, PerĂș
In Peru, only 1 % of food processing companies located in Metropolitan Lima have obtained a technical validation for their HACCP plan. The low adherence to safety systems raises the goal of identifying the main barriers and difficulties for the implementation of the HACCP system. Data was collected by sending a questionnaire to 32 companies. In order to define the underlying structure of the barriers and difficulties identified we performed an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) based on a selection of nineteen (19) items, identifying four new factors that account for 66,7 % of the overall variability. After assessing their relevance, it was found that barriers and difficulties at the organizational/managerial level (F1) and in adaptation (F4), such as infrastructure and employeeâs perception, were more relevant than attributes involving execution (F2), which comprises singular processes such as time, staff turnover, technology and others.En PerĂș, solo el 1 % de empresas de alimentos y bebidas cuentan con validaciĂłn tĂ©cnica del plan HACCP. La baja adhesiĂłn a los sistemas de inocuidad plantea el objetivo de identificar las principales barreras y dificultades para la implementaciĂłn del sistema HACCP. La recolecciĂłn de datos se realizĂł por medio de un cuestionario a 32 empresas. Para definir la estructura subyacente entre las barreras y dificultades identificadas se realizĂł el anĂĄlisis factorial exploratoria y confirmatoria a partir de 19 Ătems seleccionados, identificĂĄndose cuatro factores que explicaron el 66,7 % de la variabilidad total. Al evaluar su importancia, las barreras y dificultades a nivel organizacional/ gerencia (F1) y en la adaptaciĂłn (F4), como infraestructura y percepciĂłn de los empleados se consideraron mĂĄs relevantes que los atributos con respecto a la ejecuciĂłn (F2), donde se ve instancias de procesos singulares como el tiempo, rotaciĂłn del personal, tecnologĂa, entre otros
