description: A novel framework based on the fast orthogonal search (FOS) method coupled with factorization algorithms was proposed and implemented to realize high-accuracy muscle force estimation via surface electromyogram (SEMG). During static isometric elbow flexion, high-density SEMG (HD-SEMG) signals were recorded from upper arm muscles, and the generated elbow force was measured at the wrist. HD-SEMG signals were decomposed into time-invariant activation patterns and time-varying activation curves using three typical factorization algorithms including principal component analysis (PCA), independent component analysis (ICA), and nonnegative matrix factorization (NMF). The activation signal of the target muscle was obtained by summing the activation curves, and the FOS algorithm was used to create basis functions with activation signals and establish the force estimation model. Static isometric elbow flexion experiments at three target levels were performed on seven male subjects, and the force estimation performances were compared among three typical factorization algorithms as well as a conventional method for extracting the average signal envelope of all HD-SEMG channels (AVG-ENVLP method). The overall root mean square difference (RMSD) values between the measured forces and the estimated forces obtained by different methods were 11.79 ± 4.29% for AVG-ENVLP, 9.74 ± 3.77% for PCA, 9.59 ± 3.81% for ICA, and 9.51 ± 4.82% for NMF. The results demonstrated that, compared to the conventional AVG-ENVLP method, factorization algorithms could substantially improve the performance of force estimation. The FOS method coupled with factorization algorithms provides an effective way to estimate the combined force of multiple muscles and has potential value in the fields of sports biomechanics, gait analysis, prosthesis control strategy, and exoskeleton devices for assisted rehabilitation.

description: Given the complexity and heterogeneity of the genomic architecture underlying schizophrenia, molecular analyses of these patients with defined and large effect-size genomic defects could provide valuable clues. We established human-induced pluripotent stem cells from two schizophrenia patients with the 22q11.2 deletion (two cell lines from each subject, total of four cell lines) and three controls (total of four cell lines). Neurosphere size, neural differentiation efficiency, neurite outgrowth, cellular migration and the neurogenic-to-gliogenic competence ratio were significantly reduced in patient-derived cells. As an underlying mechanism, we focused on the role of DGCR8, a key gene for microRNA (miRNA) processing and mapped in the deleted region. In mice, Dgcr8 hetero-knockout is known to show a similar phenotype of reduced neurosphere size (Ouchi et al., 2013). The miRNA profiling detected reduced expression levels of miRNAs belonging to miR-17/92 cluster and miR-106a/b in the patient-derived neurospheres. Those miRNAs are reported to target p38α, and conformingly the levels of p38α were upregulated in the patient-derived cells. p38α is known to drive gliogenic differentiation. The inhibition of p38 activity by SB203580 in patient-derived neurospheres partially restored neurogenic competence. Furthermore, we detected elevated expression of GFAP, a gliogenic (astrocyte) marker, in postmortem brains from schizophrenia patients without the 22q11.2 deletion, whereas inflammation markers (IL1B and IL6) remained unchanged. In contrast, a neuronal marker, MAP2 expressions were decreased in schizophrenia brains. These results suggest that a dysregulated balance of neurogenic-to-gliogenic competence may underlie neurodevelopmental disorders such as schizophrenia.

Who Holds the Steering Wheel in Afghanistan? The Governor-Governed (Mis)Communication for Power, Human Rights, and Prosperity
Creators: name: Ali Ramoz, Hossain
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Political Science, General.
subject: South Asian Studies.
subject: Mass Communications.

description: This thesis examines the interrelation of the government of Afghanistan's quality and communication against a theoretical framework that draws on Bertrand Russell's (1961) Authority and the Individual and Niklas Luhmann's (1990) The Political Theory in the Welfare State. Theories of governance, communication, and participatory democracy are investigated to explore the role of media, people's political participation, citizenry, and civic activism, in good governance. The objective of this thesis is to investigate how communication influences good governance. A qualitative research design is employed, utilizing content analysis of government and non-government documents and in-depth interviews with national and international field experts. The thesis finds that effective communication can enhance the degree of responsiveness, accountability, and transparency in Afghanistan's governance system. It is argued here that effective communication between the government, external players, and the people, can improve governance quality. This thesis provides a formulation of the communication activities of the government of Afghanistan, the Afghani people, and the international community that can playa critical role in changing Afghanistan's current status as a failed state.
The evolution of Adele Wiseman's creative vision.
Creators: name: Laurin, Anne Marie.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Literature, Canadian (English).

description: The Canadian literary canon contains few writers of such diversity as Adele Wiseman. Although she is chiefly remembered for her two novels, her canon extends well beyond the fiction for which she is chiefly remembered. In fact, Wiseman was a skilled practitioner of numerous genres including drama, the essay, the short story, and the memoir. To discern the creative vision underlying Wiseman's oeuvre, this thesis devotes one chapter to each of her major works: The Sacrifice (ch. 1); The Lovebound (ch. 2); Crackpot (ch. 3); Testimonial Dinner (ch. 4); Old Woman at Play (ch. 5); and Memoirs of a Book Molesting Childhood and Other Essays and "Goon of the Moon and the Expendables" (ch. 6). While existing criticism of Wiseman's writing generally concentrates on single dimensions of her personhood (i.e. faith, gender, nationality), this thesis suggests that a more valid analysis of Wiseman's oeuvre would acknowledge its hybridity. The diversity apparent in Wiseman's canon should be seen as a reflection of her triply marginalized subject position as a Jewish Canadian female writer. As such, the thesis draws on feminist theory, post-colonial theory and Jewish hermeneutics to elucidate Wiseman's creative vision. By combining these three theoretical perspectives, one can ascertain how Wiseman's faith, gender and nationality intersected to create the unique canon she left behind. Because Wiseman was such an astute critic of her own work, this thesis relies heavily upon her own statements about her craft. The Adele Wiseman Fonds at the W. B. Scott Library, York University was an invaluable source for such information. Of particular importance was Wiseman's thirty-year correspondence with Margaret Laurence, her best friend, and Malcolm Ross, her mentor. These letters provide readers with a rare opportunity to assess Wiseman's creative vision. They confirm that Wiseman's stylistic experimentation was an outgrowth of her peripheral status in mainstream society. Her need to question and reevaluate existing literary conventions reflected her belief that such conventions were restrictive and exclusionary. Despite the heterogeneity apparent in Wiseman's work, it is nonetheless united by a single underlying vision: Wiseman writes in order to teach people how to live--particularly in communion with others. All of her writing radiates immense compassion for human beings, but especially the dispossessed. Her writing is a plea to reject hierarchical structures in society--structures which divide people into "haves" and "have-nots." She presents readers with an alternative, salutary vision of a world where such divisions are obliterated in favour of heterogeneity and an accompanying awareness of each individual's unique contribution to the whole.
On the formal methods for protocol conformance testing.
Creators: name: Lu, Yueping.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Computer Science.

description: The use of formal methods allows automated generation and optimization of test sequences. Developing formal methods for generating communications protocol conformance tests has drawn considerable attention in recent years. This thesis describes the implementation of five formal methods of protocol conformance test sequence generation proposed in the literature. These methods are: Transition tour (T) method, Distinguishing sequence (D) method, Characterizing sequence (W) method, Unique Input/Output sequence (UIO) method and Multiple UIO-method. Some related graph theoretic optimization techniques for the Chinese Postman Problem (CPP) and Rural Chinese Postman Problem (RCPP) are applied to T-method and UIO-method respectively to determine minimum-cost test sequences. It is shown in this thesis that the solution to the RCPP can also be applied to D-method and W-method to derive minimum-cost test sequences. The application of five formal methods to a real protocol, Transport protocol class 4, is then discussed.
Determinants of physical activity behaviour change in a community-based sample of middle-aged women: Integrating concepts from the theory of planned behaviour and self-determination theory

Subjects: subject: Psychology, Behavioral.

description: Despite numerous benefits associated with regular physical activity, the majority of North American women remain insufficiently active. Accordingly, researchers have examined a multitude of variables associated with women's physical activity participation. Two theoretical frameworks that may be extended to predict women's physical activity behaviour are the Theory of Planned Behaviour and Self-Determination Theory. This thesis examined physical activity behaviour change in a community based-sample of middle-aged women by integrating concepts from these two conceptual frameworks. Specific objectives were (1) to examine the relative influence of social support, TPB variables, and SDT variables on intentions to increase physical activity; (2) to assess the relative influence of intentions and motivation on physical activity behaviour change over time by testing mediating and moderating models; and (3) to examine relationships among barriers, environmental characteristics, and change in physical activity behavior. To these ends, two empirical investigations were conducted. In the first study, French-speaking women (n=109) completed a questionnaire package assessing the aforementioned variables. In the second study, English-speaking women (n=149) complete similar questionnaire packages at baseline and at six months follow-up. All women were recruited from community-based facilities, including community centres and fitness clubs. Overall, results demonstrated that attitudes, perceived behavioural control, subjective norms, and autonomous motivation were associated with intentions to increase physical activity. Intentions were also related to reported physical activity behaviour change over time. Among the most commonly reported barriers to physical activity increase were daily activities and fatigue. Inactive women reported higher levels of barriers than women who remained active or increased their physical activity level over time. Environmental characteristics (e.g., enjoyable scenery and the presence of others exercising) were also associated with change in physical activity behaviour. Collectively, results support the utility of integrating concepts from different theoretical frameworks as a means of understanding physical activity behaviour change and physical activity behaviour change intentions. Findings also suggest a number of ways in which physical activity behaviour change could be fostered in middle-aged women.
Migration and in vivo transfection of cells in the regeneration caudal fin of zebrafish.
Creators: name: Brown, Christoper W.

Year: 1998
Subjects: subject: Biology, Molecular.

description: Limb regeneration has been most intensively studied in the urodele amphibians, however, the refinement of the danio rerio, zebrafish, as a genetic system permits the study of the genetic control of development and regeneration on a much larger scale. In addition, the epimorphic regeneration process of the zebrafish fin is very similar to the regeneration process of the tetrapod limbs, with the advantage that the fin presents a relatively simple anatomy, and complete restoration of the regenerate within a few weeks. Two specific aims have been studied. On a cellular level, in order to specify the origin of cells that contribute to the regenerate, we used the lipophilic carbocyanine dye, Di-I, to label and subsequently to characterize the epidermal and mesenchymal cell contributions from the stump tissue of the caudal fin to the regenerate. On a molecular level, we investigated a method to introduce genes of interest into the regenerating caudal fin. By injecting Green Fluorescent Protein (GFP) reporter constructs into the blastema of regenerating caudal fins, we successfully transfected blastemal cells. Using this approach, we try to misexpress the sonic hedgehog gene in the regenerating fin in order to further investigate the function of this gene in the formation and patterning of the dermal bone of the fin.

description: Background The aim was to estimate the impact of individual risk factors and treatment with various disease-modifying antirheumatic drugs (DMARDs) on the incidence of myocardial infarction (MI) in patients with rheumatoid arthritis (RA). Methods We analysed data from 11,285 patients with RA, enrolled in the prospective cohort study RABBIT, at the start of biologic (b) or conventional synthetic (cs) DMARDs. A nested case–control study was conducted, defining patients with MI during follow-up as cases. Cases were matched 1:1 to control patients based on age, sex, year of enrolment and five cardiovascular (CV) comorbidities. Generalized linear models were applied (Poisson regression with a random component, conditional logistic regression). Results In total, 112 patients developed an MI during follow-up. At baseline, during the first 6 months of follow-up and prior to the MI, inflammation markers (erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)) but not 28-joint-count disease activity score (DAS28) were significantly higher in MI cases compared to matched controls and the remaining cohort. Baseline treatment with DMARDs was similar across all groups. During follow-up bDMARD treatment was significantly more often discontinued or switched in MI cases. CV comorbidities were significantly less often treated in MI cases vs. matched controls (36 % vs. 17 %, p

The ethics of authenticity: Heidegger's retrieval of the Kantian ethic in "Being and Time"
Creators: name: Stephenson, Erik H
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Philosophy.

description: The purpose of this study is twofold: first, to unearth the ethic implicit in, or, better, the possible ethical implications of, Heidegger's Being and Time; and, second, to demonstrate the exact manner in which its latent ethic or ethical bearing, involves a retrieval of the Kantian ethic as Heidegger casts it. Specifically, it is argued that, in summoning Dasein to its authenticity, the call of conscience commands self-responsibility, respect for one's dignity as end-in-itself, preservation of one's ownmost potentiality-for-being as possibility, and 'philosophizing', understood as a radical and perpetual (self)questioning. Furthermore, it is shown that these self-directed imperatives entail certain obligations towards Others. Ultimately, the Heideggerian 'ethic of authenticity' is criticized for its excessive emphasis on the form of the will, as opposed to its content. While the study demonstrates how almost every one of the obligations to which Dasein is summoned by the call of conscience can be said to have been retrieved through Heidegger's appropriative reading of Kant, the study's chief conclusion is that the Heideggerian ethic's almost exclusive attention to the how of Dasein's being can be retraced to a certain, voluntaristic strand in the early Heidegger's interpretation of the Kantian ethic.

description: Depuis la fondation du club de hockey des Canadiens de Montréal, au début du XXe siècle, les Québécois se sont identifiés à cette équipe et plus particulièrement, au fil des époques, à certains joueurs, au premier rang desquels Maurice Richard, qui a atteint le statut de héros. Le hockey faisant partie de l'identité socioculturelle du Québec, nous nous sommes intéressée à la place qu'il occupe dans la littérature québécoise. Pour ce faire, nous avons choisi la perspective de l'imaginaire, défini notamment comme la manifestation d'un inconscient collectif d'où sont tirées des images servant de fondement à la création artistique. Ces images véhiculent ainsi des références culturelles propres à un peuple. Le choix de Roch Carrier et de Jacques Poulin s'est imposé à nous pour un certain nombre de raisons, la premiere étant, évidemment, la présence récurrente du hockey dans leurs romans publiés depuis les années 1960 jusqu'à aujourd'hui. Notre thèse met donc en relief les manières plurivoques de ces deux écrivains d'utiliser le hockey comme moteur de l'imaginaire dans leurs romans.

Year: 1999
Subjects: subject: Computer Science.

description: The rapid growth of new services for telecommunication and multimedia systems is being challenged by the feature interaction problem. A number of approaches for managing feature interaction have been proposed. A relational method for specifying software systems and detecting features interactions is presented. The method proposed allows features to be specified independently as well as detecting interactions between two or more features. This method is based on the lattice of relational specifications; a system is defined by the conjunction of the features and feature interaction is detected when such a conjunction does not exist. After reading this thesis a reader should be able to specify a simple system and detect interactions between its features.

A feminist content analysis of the popular and health professional literatures on infant feeding, 1960-1996.
Creators: name: Soklaridis, Sophie.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Women's Studies.

description: A feminist content analysis examines how the popular and health professional literatures discuss infant feeding practises from the 1960's to 1996. Three research questions were constructed to address women's role(s) and obligations as mothers with respect to infant feeding. The first research question examined the advantages and disadvantages associated with particular methods of infant feeding. The second research question examined how (if at all) a woman's time, energy, and bodily fluids are appropriated, and how the development of self-actualisation might be connected to infant feeding practise. The third research question examined how the popular and health professional literatures discussed the various support systems available to the mother in order to analyse the way in which the mother is situated culturally and socially. The results of the three were theorized and operationalized using the concepts of alienation, appropriation of women, self-actualisation, and diversity. These various concepts were found within socialist and materialist feminism and social psychology.
Educational Data Mining and the Validity of the Index of Learning Styles

description: Dr Shobbrook's research uses Educational Data Mining in a mixed method to investigate the validity of the Felder-Silverman Model of learning styles, a model developed for engineering education. The results show that for a minority of students there was some alignment between the model's predictions for one of their learning style's dimensions; however, the majority of student resource selections and perceptions did not correlate with the predictions of the model. This research concludes that this learning styles model has insufficient predictive power to be accepted as a strategy for improving learning outcomes.

description: We propose a novel localized sensor placement algorithm for wireless sensor networks, named Back-Tracking Deployment (BTD). Through simulation we show that BTD far outperforms the only competing algorithm LRV [2] in robot moves and robot messages at no additional cost in a failure-free environment and at minimal cost of sensor messages in a failure-prone environment. Further, we propose the first localized carrier-based sensor relocation algorithm for wireless sensor networks, named Randomized Robot-assisted Relocation of Static Sensors (R3S2). We also presented a grid-based variant, called G-R3S2 and a cluster-based variant, called C-R3S2 and C-G-R3S2. Through extensive simulation, the effectiveness and practicality is shown. The simulation results indicate in particular that robots following the LRV policy (G-R3S2 and C-G-R3S2) outperformed those that did not across all measured metrics. Further, the cluster-based variants outperformed their counterpart (C-G-R3S2 vs. G-R3S2 and C-R3S2 vs. R3S2) across all metrics.

description: Based on our previous finding of a seven-miRNA (hsa-miR-34a, miR-449a, miR-564, miR-432, miR-548d, miR-572 and miR-652) signature as a potential biomarker for schizophrenia, this study aimed to examine if hospitalization could affect expressions of these miRNAs. We compared their expression levels between acute state and partial remission state in people with schizophrenia (n=48) using quantitative PCR method. Further, to examine whether the blood and brain show similar expression patterns, the expressions of two miRNAs (hsa-miR-34a and hsa-miR-548d) were examined in the postmortem brain tissue of people with schizophrenia (n=25) and controls (n=27). The expression level of the seven miRNAs did not alter after ~2 months of hospitalization with significant improvement in clinical symptoms, suggesting the miRNAs could be traits rather than state-dependent markers. The aberrant expression seen in the blood of hsa-miR-34a and hsa-miR-548d were not present in the brain samples, but this does not discount the possibility that the peripheral miRNAs could be clinically useful biomarkers for schizophrenia. Unexpectedly, we found an age-dependent increase in hsa-miR-34a expressions in human cortical (Brodmann area 46 (BA46)) but not subcortical region (caudate putamen). The correlation between hsa-miR-34a expression level in BA46 and age was much stronger in the controls than in the cases, and the corresponding correlation in the blood was only seen in the cases. The association between the miRNA dysregulations, the disease predisposition and aging warrants further investigation. Taken together, this study provides further insight on the candidate peripheral miRNAs as stable biomarkers for the diagnostics of schizophrenia.

description: This thesis describes the design and the implementation of a security architecture for an e-hospital. The e-hospital uses mobile agent technologies in its function implementation. The mobile agent technology has notable advantages over the traditional client/server technology. However, its advantages make it more vulnerable to threats. We use ISO17799, an international standard for Information security management, as our guide to approach the security problems in this e-hospital. We reach the security objectives for this e-hospital by risk assessments of the current system, compliance with the patients' privacy protection regulations and the consideration of end users' requirements. We divide the whole e-hospital into different domains according to their security levels and propose protections for each domain. We use identity-based two party key agreement protocols to address the network security in this e-hospital. Finally, we extend Bagga and Molva's policy-based cryptographic scheme to address the end user's access control and non-repudiation. Our proposed cryptographic scheme is based on the hardness of the Generalized Bilinear Diffie-Hellman Problem (GBDH problem) in groups. We implement our proposed cryptographic scheme in Java. The test results show that the performance of our proposed cryptographic scheme is acceptable using the elliptic curve defined over large prime fields.

description: Barth Syndrome (BTHS) is a rare X-linked genetic disease in which the specific biochemical deficit is a reduction in the mitochondrial phospholipid cardiolipin (CL) as a result of a mutation in the CL transacylase tafazzin. We compared the phosphokinome profile in Epstein-Barr-virus-transformed lymphoblasts prepared from a BTHS patient with that of an age-matched control individual. As expected, mass spectrometry analysis revealed a significant (>90%) reduction in CL in BTHS lymphoblasts compared to controls. In addition, increased oxidized phosphatidylcholine (oxPC) and phosphatidylethanolamine (PE) levels were observed in BTHS lymphoblasts compared to control. Given the broad shifts in metabolism associated with BTHS, we hypothesized that marked differences in posttranslational modifications such as phosphorylation would be present in the lymphoblast cells of a BTHS patient. Phosphokinome analysis revealed striking differences in the phosphorylation levels of phosphoproteins in BTHS lymphoblasts compared to control cells. Some phosphorylated proteins, for example, adenosine monophosphate kinase, have been previously validated as bonafide modified phosphorylation targets observed in tafazzin deficiency or under conditions of reduced cellular CL. Thus, we report multiple novel phosphokinome targets in BTHS lymphoblasts and hypothesize that alteration in the phosphokinome profile may provide insight into the pathophysiology of BTHS and potential therapeutic targets.

description: We report on 2.4 yr of radio timing measurements of the magnetar PSR. J1622-4950 using the Parkes Observatory, between 2011 November and 2014 March. During this period the torque on the neutron star (inferred from the rotational frequency derivative) varied greatly, though much less erratically than during the 2 yr following its discovery in 2009. During the last year of our measurements the frequency derivative decreased in magnitude monotonically by 20%, to a value of -1.3. x. 10(-13) s(-2), a factor of 8 smaller than when it was discovered. The flux density continued to vary greatly during our monitoring through 2014 March, reaching a relatively steady low level after late 2012. The pulse profile varied secularly on a similar timescale as the flux density and torque. A relatively rapid transition in all three properties was evident in early 2013. After PSR. J1622-4950 was detected in all of our 87 observations up to 2014 March, we did not detect the magnetar in our resumed monitoring starting in 2015 January and have not detected it in any of the 30 observations conducted through 2016 September.

description: The peritoneum plays an essential role in preventing abdominal frictions and adhesions and can be utilized as a dialysis membrane. Its physiological ultrastructure, however, has not yet been studied systematically. 106 standardized peritoneal and 69 omental specimens were obtained from 107 patients (0.1–60 years) undergoing surgery for disease not affecting the peritoneum for automated quantitative histomorphometry and immunohistochemistry. The mesothelial cell layer morphology and protein expression pattern is similar across all age groups. Infants below one year have a thinner submesothelium; inflammation, profibrotic activity and mesothelial cell translocation is largely absent in all age groups. Peritoneal blood capillaries, lymphatics and nerve fibers locate in three distinct submesothelial layers. Blood vessel density and endothelial surface area follow a U-shaped curve with highest values in infants below one year and lowest values in children aged 7–12 years. Lymphatic vessel density is much lower, and again highest in infants. Omental blood capillary density correlates with parietal peritoneal findings, whereas only few lymphatic vessels are present. The healthy peritoneum exhibits major thus far unknown particularities, pertaining to functionally relevant structures, and subject to substantial changes with age. The reference ranges established here provide a framework for future histomorphometric analyses and peritoneal transport modeling approaches.

description: Immer mehr Menschen wollen, dass für von ihnen verursachte klimaschädliche Emissionen an anderer Stelle entsprechende Treibhausgase vermieden werden. Ein Beispiel sind Kompensationen für Flugreisen, die Reisebüros und Fluggesellschaften ihren Kunden schon bei der Buchung anbieten. Allerdings gibt es für freiwillige Kompensation kein zentrales Anerkennungsverfahren und keinen einheitlichen, verbindlichen Standard. Dies kann zu schwankender Qualität auf einem für VerbraucherInnen unübersichtlichem Markt führen. Die Marktanalyse zeigt: Der Markt für freiwillige Kompensation von Treibhausgasen erweist sich als krisenfest. Während der Verpflichtungsmarkt sich zum Teil schwierigen Marktbedingungen ausgesetzt sieht, hat sich der Markt für freiwillige Kompensationen in den letzten Jahren dynamisch weiter entwickelt und ausdifferenziert.

description: The fate and persistence of the pesticide, fenitrothion (O,O-dimethyl-O (3-methyl-4-nitrophenyl)phosphorothioate) was monitored in the presence of the alga Chlamydomonas segnis Ettl. Under natural sunlight (800 w m$\sp{-2}$) and Vita Lite$\sp{\rm R}$ high intensity fluorescent lamps (Dura Test, 50 w m$\sp{-2}$, 290-700 nm), there was 10 to 20 times the uptake of $\sp $C ring-labelled fenitrothion into live and freeze-killed algae as compared to dark conditions. The accumulated label in both the live and freeze-killed algae (with nonfunctioning electron transport systems) was identified as polar metabolites of fenitrothion, their identical percentages suggesting photophysical reactions. As a consequence of increased uptake and degradation of fenitrothion by live algae, the fenitrothion half-life in the media decreased by approximately one half in the presence of algae and light, as compared to lighted media controls. When accumulation experiments were repeated under anaerobic conditions, polar metabolites were reduced by 50%. Further, as increased pigment chlorosis correlated with increased polar metabolites, it is suggested that photooxidation of fenitrothion by singlet oxygen could have been a degradation route. Fenitrothion photolysis was accelerated by the aquatic alga, Chlamydomonas segnis.
