Auto-ignition of liquid droplets of single and two component fuels under pressure.
Creators: name: Chen, Titus S.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Engineering, Automotive.

description: Experimental measurements and model predictions of ignition delay times for single component and two-component liquid fuels are presented. The methodology used is the suspended-droplet/moving-furnace technique, in which a droplet of fuel is suspended from the tip of a thin quartz fibre. A preheated electric furnace moves towards and encompasses the droplet locality, producing a sudden rise in ambient temperature, and thus initiating the ignition process. The entire apparatus is enclosed in a pressure vessel and is remotely operated. Data were collected for pressures up to 18 atm absolute and in a temperature range of 773 K to 973 K. Fuels tested comprised n-paraffins (decane, dodecane, and hexadecane), aromatics (mesitylene, o-xylene, and isobutylbenzene) and a cycloparaffin (decalin), as well as selected binary combinations: n-decane/n-dodecane, n-dodecane/n-hexadecane, n-decane/decalin, n-decane/isobutylbenzene, n-decane/mesitylene, and n-decane/o-xylene. Paraffin measurements at low pressures and high temperature revealed a monotonic decrease in ignition times with increasing pressure. However, higher pressure ignitions at lower temperatures showed more complex behaviour by the measurement of two or "twinned" ignition times for the same pressure and temperature condition, indicating a change in reaction mechanism, possibly from one-stage to two-stage ignition. Aromatic fuels did not show "twinned" ignition time behaviour and responded with a slight increase in ignition times with increasing pressure, owing to a weaker reaction rate dependence on pressure. The cycloparaffin behaved analogously to the n-paraffin family. The behaviour of mixtures was largely controlled by the more volatile component. (Abstract shortened by UMI.)

description: Directing the geometry of membranes is a goal shared by many disciplines. From designing drug delivery systems in bioengineering to understanding how membranes regulate their size and shape in physics, the study of structural transitions of membranes offers many potential insights into membrane assembly. However, biological membranes operate on small length and time scales that make it difficult to examine the physics behind biomembrane configuration using standard microscopy techniques. Here, we present an experimental model system consisting of colloidal membranes that can be used to study the universal physics driving membrane restructuring. These colloidal membranes are much larger than lipid membranes, making them easily accessible to standard microscopy techniques, such as confocal microscopy. Colloidal membranes are assembled from rod-shaped filamentous viruses through the depletion interaction. The preferred membrane configuration can be promoted by tuning the physical parameters of the filamentous viruses, such as length and chirality, through biomolecular techniques, as well as altering the environment surrounding the membranes. Primarily, we use the system to examine the universal physics governing vesicle formation, in which the membrane transitions from a two-dimensional flat sheet to a three-dimensional closed hollow shell. We find that vesicle formation in the colloidal membrane system depends on the thickness of the membrane, which is set by the virus length. Moreover, we record the transition via confocal microscopy, giving us a direct look at vesicle formation. Additionally, we study how heterogeneity affects in-plane membrane organization. Length asymmetry between two rod populations leads to the formation of domains within membranes, indicating that constituent length is an important physical characteristic in determining membrane configuration. Finally, we investigate transitions from flat sheets to one-dimensional twisted ribbons. We study the link between membrane constituent chirality and overall ribbon structure. Through this research, we find insights into the physics driving membrane reconfiguration and how the physical properties of membrane constituents affect membrane structure.
The nature of marriage as proposed in the codex iuris canonici and in the codex canonum ecclesiarum orientalium.
Creators: name: Connolly, Patrick J.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Law.

description: When one quickly glances at the new 1990 Oriental Code, one gets the impression that the marriage legislation is substantially the same as that found in the 1983 Latin Code. This cannot be surprising since the canon law on Christian marriage concerns a sacrament of the Church and therefore one would expect that it should be much the same throughout the Catholic Church, in the Western and in the Eastern Churches. However, because of the diversity of traditions, there are differences in theological approach and matters of discipline in respect of marriage. One such difference concerns the description of the nature of marriage in each Code. This comparative study addresses a number of questions regarding the nature of marriage as proposed in the two legislations. What are the common elements in both Codes' descriptions of marriage's nature? Do both legislations fully reflect the teaching of Vatican II's Gaudium et spes? What precisely are the differences between the two Codes? What is the origin and significance of these differences? Is the Oriental legislation faithful to the tradition of the Eastern Churches? The dissertation begins by attempting a synthesis of the historical and theological background of the Church's thinking on marriage in East and West, which will help explain the different approaches found in the two Codes, and which will also assist in assessing to what extent the new Oriental Code is indeed faithful to authentic Eastern traditions. The thesis goes to thoroughly elucidate the contribution of the Second Vatican Council and to survey the post-conciliar magisterial documents and the jurisprudence of the Roman Rota. This is essential in order to evaluate the ways that the two new legislations reflect the teaching of the Council. There is then a detailed examination of the two Code Commissions' work in drafting the Church's new legislations on marriage, to try to ascertain the reasoning behind their choices of formulations. All of this enables the final part of the work to investigate the common and different approaches by the two Codes in describing marriage's nature; this involves an in-depth comparison and analysis of the relevant canons.
A data-based power transformation for compositional data

description: Compositional data analysis is carried out either by neglecting the compositional constraint and applying standard multivariate data analysis, or by transforming the data using the logs of the ratios of the components. In this work we examine a more general transformation which includes both approaches as special cases. It is a power transformation and involves a single parameter, α. The transformation has two equivalent versions. The first is the stay-in-the-simplex version, which is the power transformation as defined by Aitchison in 1986. The second version, which is a linear transformation of the power transformation, is a Box-Cox type transformation. We discuss a parametric way of estimating the value of α, which is maximization of its profile likelihood (assuming multivariate normality of the transformed data) and the equivalence between the two versions is exhibited. Other ways include maximization of the correct classification probability in discriminant analysis and maximization of the pseudo R-squared (as defined by Aitchison in 1986) in linear regression. We examine the relationship between the α-transformation, the raw data approach and the isometric log-ratio transformation. Furthermore, we also define a suitable family of metrics corresponding to the family of α-transformation and consider the corresponding family of Frechet means.

Campus Anti-Violence Resources: A Multi-Institutional Analysis of Student Awareness, Access, and Experience
Creators: name: Hagani, Alison
Publisher: name: Brandeis University
Year: 2022
Subjects: campus sexual violence, resource use, institutions, violence, campus agendas

description: Using quantitative methods, this research analyzes how college students in Connecticut who have experienced sexual violence evaluate and navigate campus resources. Survey respondents disclosed a greater use of non-punitive and non-institutionalized resources, with disclosure to friends as the most accessed resource. Despite this, respondents valued their college/university’s confidential support resources just as much. Students were also more likely to be aware of and value their college/university’s confidential support resource when housed on campus in the form of a university-specific confidential resource center rather than off-campus in the form of a state-governed memorandum of understanding. These findings expose a potential overburdening of peers as sources of support, where non-punitive, campus-sponsored confidential resources are both valued and needed. Furthermore, my research found that barriers to accessing resources were most pronounced for punitive resources, but were still evident among non-punitive, institutionalized resources. Students disclosed witnessing and experiencing conflicting university agendas that invalidated their experiences of alleged violence and attempts at seeking recourse. The array of resources available to students, all of which face differing levels of awareness and access, speaks to the multiple institutions that govern campus sexual violence and the ways their organizational frames and capabilities vary.

description: Background International phytosanitary standards ISPM 15 require (since 2007) fumigation or heat treatment for shipping and storage. Those dealing with fumigated freight might be accidentally exposed. In this paper we report a series of three accidents of six storage room workers in a medium sized company regularly importing electronic production parts from abroad. Methods Patients (n = 6, aged from 32–54 yrs.) and control group (n = 30, mean 40 yrs.) donated blood and urine samples. The fumigants: ethylene oxide, methyl bromide, chloropicrin, ethylene dichloride, other halo-alkanes and solvents were analyzed by headspace gas chromatography/mass spectrometry (GCMS). For the quantitation of long term exposure/s, macromolecular reaction products (hemoglobin adducts) were used (with GCMS) as molecular dosimeter; additionally 8-OHdG and circulating mtDNA (cmtDNA) were analyzed as nonspecific biological effect markers. Results The hemoglobin adducts N-methyl valine (MEV) and N-(2-hydroxy ethyl) valine (HEV) were elevated after exposure to the alkylating chemicals methyl bromide and ethylene oxide. Under the consideration of known elimination kinetics and the individual smoking status (biomonitored with nicotine metabolite cotinine and tobacco specific hemoglobin adduct: N-(2 cyan ethyl) valines, CEV), the data allow theoretical extrapolation to the initial protein adduct concentrations at the time of the accident (the MEV/CEV levels were from 1,616 pmol/g globin to 1,880 pmol/g globin and HEV/CEV levels from 1,407 pmol/g globin to 5,049 pmol/g globin, and correlated with inhaled 0.4-1.5 ppm ethylene oxide. These integrated, extrapolated internal doses, calculated on the basis of biological exposure equivalents, confirmed the clinical diagnosis for three patients, showing severe intoxication symptoms. Both, cmtDNA and 8-OHdG, as non-specific biomarkers of toxic effects, were elevated in four patients. Conclusion The cases reported here, stress the importance of a suitable risk assessment and control measures. We put emphasis on the necessity of human biomonitoring guidelines and the urgency for the relevant limit values.

Repondant a cette valeur dominante, l'industrie sportive s'implique dans le rationnel de cette guerre a la drogue en developpant un controle "para-judiciaire", c'est-a-dire des politiques et des sanctions internes au milieu sportif en matiere de drogues illicites. Pour mieux comprendre le fondement de ces controles dans l'industrie sportive, a la suite de ma revue de litterature, j'ai fait une recension journalistique de tout les cas mediatises de joueurs professionnels, qui ont avoue ou ont ete pris a consommer des drogues illicites, depuis 1986 a 1991. L'analyse de ces cas nous a permis de constater que non seulement les industries impliquees dans le sport professionnel avaient interet a repondre a la valeur dominante du "drug-free nation" pour proteger la rentabilite du sport-spectacle, mais que cela leur permet de mettre en place des mecanismes de controle sur leurs employe-e-s qui vont bien au-dela de la question des drogues et ce, plus particulierement par l'implantation des tests de depistage des drogues illicites.

Role and production of secretoneurin (SN) in the goldfish pituitary
Creators: name: Zhao, E
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: Biology, Genetics.

description: Secretoneurin (SN) is a 33--34 amino acid neuropeptide derived from secretogranin II (SgII), a protein belonging to the chromogranin family. In static incubation studies, SN (10--500 nM) had a direct effect on pituitary fragments to increase luteinizing hormone (LH) release after 3-hour treatment. SN also induced a specific 2.6-fold increment of LHbeta subunit messenger RNA levels after 6-hour treatment. Using a western blot analysis with a polyclonal rabbit anti-SN antibody, two intermediate proteins (∼57 kDa and ∼30 kDa) likely processed from the 69.6-kDa SgII precursor were detected in the goldfish pituitary. Levels of the ∼57-kDa SN-immunoreactive protein were ∼5-fold higher in the pars distalis than the neurointermediate lobe. In summary, SN has a direct stimulatory action on LH release and synthesis. High production of SN-containing proteins in the pars distalis of the pituitary suggests the existence of a local SN-mediated mechanism to regulate LH in goldfish.
Establishing and validating a measure of the Japanese concept of self
Creators: name: Mizuno, Hitomi
Publisher: name: Swinburne
Year: 2024

description: The thesis established a scale to measure the Japanese concept of self, based on traditional Japanese self-concept theories. Statements from these theories were developed into a self-report questionnaire which was administered to 500 Japanese participants. Exploratory factor analysis produced four factors: lnterpersonal Anxiety, Harmony, Self-Centredness, and connectedness. A second questionnaire using this scale was administered to both Japanese and Australian participants for validation and comparison. Confirmatory factor analysis supported the scale structure and comparison with existing widely used measures validated its content. The scale presents opportunities for scholars to compare the Japanese concept of self with a wide variety of behaviours.

description: This collection of poetry explores the multiple tipping points facing humanity at the opening of the 21st century and the end of the industrial age. Resource depletion, species loss and global warming are just a few of the existential threats examined in this work. I believe that the way beyond these crises requires examining the narratives we're inherited and imagining new tales of people, place and planet that can deliver us to a more ecologically just future. This thesis is an offering toward that end. At the Unmaking is a lament for what we have lost and are losing. It is also a prayer calling up the wisdom required to remake our lives in a more interconnected and whole way. All unmaking and making demands stories about where we have been and where we might go. I have written these poems not to mark an end, but to mark the eternal return to a new beginning.

description: In 264 BCE, the Etruscan city of Velzna fell to the Romans, who destroyed the homes and other structures on top of the tufa plateau now known as Orvieto, Italy. Orvieto’s unique soft-rock plateau allowed its Etruscan inhabitants to dig wells, cisterns, and tunnels and today 1,200 artificial cavities are documented beneath the city. Archaeologists investigating these structures hope to uncover what the Etruscan city of Velzna looked like prior to its demise. This thesis examines Cavità 254 a unique type of underground structure found beneath Orvieto. Cavità 254 is the first Etruscan pyramidal hypogeum structure to be systematically excavated beneath the city of Orvieto. Since the discovery of Cavità 254 in 2012, the site has enthralled and motivated archaeologists to determine the original function of the site. This thesis presents new excavation evidence of quarrying techniques uncovered on the walls of Cavità 254 and the use of the site as a quarry in Etruscan Velzna. Cavità 254 was filled with various types of materials from the Etruscan occupation of Orvieto at the end of the fifth century BCE. The Fifth century in Etruria was a time of change in political structure that replaced the rule of kings with magistrates. As political culture shifted, efforts to appease a population governed by its own peers began. New buildings were constructed for public use as older buildings were torn down erasing the kingship in Etruria. This major social shift is precisely what occurred in Velzna in the fifth century BCE. Political changes motivated new building efforts and Cavità 254 and other quarries used for now out of date buildings were filled in the fifth century to make way for new public structures.

description: Autonomous robot navigation is a complex processing task which can be broken down in several levels. These levels are Robot Control, Sensor Interpretation, Sensor Integration, Real-World Modelling, Navigation, Global Planning and Control. The work done in this thesis addresses the first four of these levels in order to generate an accurate environment model from sensory data. A real world mapping system was developed and implemented for a mobile platform evolving in an unstructured environment. The system uses sonars as the source of sensory data. A certainty-grid based mapping method is used to map and merge the sonar data onto a pixel representation. For the purpose of this research, a user-friendly application is used to provide a test platform and demonstrate the system capabilities.

description: Therapeutics Letter 106 examines Cochrane systematic review evidence on antihypertensives for treatment of high blood pressure. Conclusions: Antihypertensive drug treatment modestly reduces mortality and morbidity in people ≥ 60 with moderate to severe hypertension (>160/100). Low-dose thiazide diuretics are the best drug class for starting therapy. In mild hypertension (140-159/90-99) antihypertensive drugs have not been proven to reduce mortality and morbidity. Blood pressure treatment targets should be those used in RCTs (<140-160/90-100), as lower BP targets have not been shown to have a net health benefit.

For protocol I, ACE mRNA and activity in the hypothalamus and pons, as well as in the left ventricle (LV) and right ventricle (RV); angiotensin I and II (Ang I, II) in the hypothalamus and pons, as well as in the ventricle and plasma, and plasma renin activity (PRA) were assessed in Dahl salt-sensitive (Dahl S) and salt-resistant (Dahl R) rats on high (1370 mumol/g) or regular salt (120 mumol/g) diet for 2 or 4--5 weeks. For protocol II, ACE mRNA and activity in the hypothalamus and pons, and in the LV and RV were measured in Dahl S rats on high salt with either icv Fab fragments binding brain "ouabain" or gamma-globulins as control, or, regular salt with icv gamma-globulins; and in Dahl R rats on high or regular salt diet for 4--5 weeks.

System dynamics simulation of a thermal water quality trading market
Creators: name: Bier, Asmeret Brooke
Publisher: name: Washington State University
Year: 2009
Subjects: Water quality trading -- Economic aspects

description: Thermal water quality trading is an emerging policy tool for managing water temperature. Temperature trading programs give point source thermal polluters the option to comply with effluent restrictions by paying nearby landowners to plant shade trees. The shade trees cool the water, offsetting the thermal pollution emitted by the point source. Thermal trading has the potential to create greater environmental benefits at a lower cost than traditional regulation. However, only one thermal trading program has been implemented to date. The Riparian Shading Simulator is a system dynamics model of a hypothetical thermal water quality trading program. Three distinct uses of the Riparian Shading Simulator are described here. First, it is used as part of a classroom exercise meant to teach participants about the structure, dynamics, and potential benefits and drawbacks of a thermal water quality trading market. In this exercise, players negotiate with each other to initiate trades, and are informed about shading and water temperature through a model interface. The simulation and subsequent discussion help to teach participants about policy design issues and sources of uncertainty. Second, the Riparian Shading Simulator is used to explore the consequences of trading policy designs with varying trading ratios and upstream-only rules. Results from this analysis can be used to help choose a trading ratio that balances the goals of enhancing ecosystem services and reducing costs. Finally, the model is used to conduct an uncertainty analysis of a thermal water quality trading program. The analysis considers uncertainties about climate change, environmental stochasticity, and trading behavior, and looks at the effects of each of these separately, as well as how they might affect program outcomes when combined. Results of the uncertainty analysis indicate that even with a high trading ratio, it might not be possible to reduce river temperatures sufficiently to comply with water quality standards. However, the use of trading ratios means that trading programs are likely to create larger temperature reductions than would be achieved with conventional regulation strategies.

title: From Church Work to Social Work and Beyond: A Study of the Involvement of the Churches in the Social Work Profession in Britain
Creators: name: Whiting, Russell Lewis
Publisher: name: Goldsmiths, University of London
Year: 2003

description: The study is an examination of the professional social work carried out under the auspices of the churches in Britain. Research is based on a literature review, a small number of unpublished documents and for the most part on material obtained from 28 interviews with church social workers and church social work managers, some of whom are now retired, many of whom are still active in their places of work. The time frame is within the living memory of the interviewees, the last 40 years or so, although the study is very much concerned with how the earlier history shaped different aspects of the work. Part One begins, through the literature review, by tracing the origins of church social work in late 19th and early 20th Century church philanthropy. It moves on to survey what is suggested was the core manifestation of church social work in Britain in the mid 20th Century, moral welfare work. The review concludes with an examination of what has happened to church social work since the demise of moral welfare work. Published material on church social work dries up after the early 1970s. A central aim of the study is therefore to provide updated information on the current situation and the second chapter, a collection of extended interview extracts, allows space for church social workers to do this themselves. Part Two of the study consists of analysis of four different aspects of church social work: its reputation, its organisation, its theology and its place within modern society. Material drawn from the interviews is used to supplement and update analysis of published works. Part Three is a review of the study. It contains an outline of the methodological framework and a self-critique of choices made. A final chapter draws together the conclusions of the study.

description: Introduction Volumetric muscle loss (VML) is one of the most severe and debilitating conditions in orthopedic and regenerative medicine. Current treatment modalities often fail to restore the normal structure and function of the damaged skeletal muscle. Bioengineered tissue constructs using the patient’s own cells have emerged as a promising alternative treatment option, showing positive outcomes in fostering new muscle tissue formation. However, achieving timely and proper innervation of the implanted muscle constructs remains a significant challenge. In this study, we present a clinically relevant strategy aimed at enhancing and sustaining the natural regenerative response of peripheral nerves to accelerate the innervation of biofabricated skeletal muscle implants. Methods We previously developed a controlled-release neurotrophic factor delivery system using poly (lactic-co-glycolic acid) (PLGA) microspheres encapsulating ciliary neurotrophic factor (CNTF) and glial cell line-derived neurotrophic factor (GDNF). Here, we incorporate this neurotrophic factor delivery system into bioprinted muscle constructs to facilitate innervation in vivo. Results Our results demonstrate that the neurotrophic factors released from the microspheres provide a chemical cue, significantly enhancing the neurite sprouting and functional innervation of the muscle cells in the biofabricated muscle construct within 12 weeks post-implantation. Discussion Our approach provides a clinically applicable treatment option for VML through accelerated innervation of biomanufactured muscle implants and subsequent improvements in functionality.
Investigating speed issues in acoustic-phonetic models for continuous speech recognition

Subjects: subject: Engineering, Electronics and Electrical.

description: Automatic Speech Recognition applications face two challenges: accuracy and speed. For good accuracy, Dynamic Programming and Hidden Markov Model algorithms are widely used despite their heavy computational load. To solve the speed problem, this thesis uses a Three-Stage-Architecture (TSA) in which Stage.1 is to enhance and extract features from the input speech signal, Stage.2 does a phonetic-acoustic level recognition to output strings of phonemes to Stage.3 that completes the recognition into valid words using HMM on strings rather than utterances processing. We designed two algorithms for Stage.2: Fast Two-Level Dynamic Programming (FTLDP) that is 20 times faster than a standard Two-Level DP and ParrallelRecognizer that performs 320 times faster than the standard Two-Level DP. Both algorithms are combined with a heuristic feature called Cepstrum Gain Envelop Profile (CGEP) based Silence Detection to shorten the input speech and clustering to reduce the search space in the reference phonetic models.
Protocol validation and implementation: A design methodology using LOTOS and ROOM.
Creators: name: Hart, Neil Darren.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Computer Science.

description: Formal methods have been proposed as a means of expediting the creation of reliable software. The use of formal methods allows for clear and unequivocal specification of a system's design, and makes possible a form of prototyping that allows for formal validation against system requirements. However, the adoption of formal methods by industry has so far been slow. It is proposed that one of the obstacles to the adoption of formal methods is the difficulty of bridging the gap between a formally-specified system and a working implementation. If this gap is too wide, the advantages of formal specification will be lost in the transition to implementation. The methodology described in this thesis attempts to close this gap by demonstrating how a system may be described using LOTOS (Language Of Temporally-Ordered Specifications) and validated against requirements using two techniques: composition with agent scenarios and temporal logic model checking. The methodology then allows for the derivation of a model in the ROOM (Real-Time Object-Oriented Modelling) notation, which may be automatically converted to an implementation in the C++ programming language. The methodology is illustrated with two small case studies. The first is the GPRS Tunnelling Protocol, used for transmitting protocol data units within the network of the General Packet Radio Service. The second study concerns authentication of users of the POP3 Internet mail protocol and demonstrates inheritance in LOTOS. Together, these case studies illustrate the salient points of the design methodology.
Distributed algorithms for file sorting and shortest path finding.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Computer Science.

description: The thesis consists of four chapters. Chapter one lays out the foundations of distributed computing. Chapter two presents new decentralized algorithms for sorting files of integers stored in a distributed and asynchronous network. An optimal communication complexity O(n log$\sb2$d) is obtained under the assumption that extra memory is available at each site in an almost balanced binary tree network, where n is the file size and d is the number of nodes in the network. When extra memory is removed from the nodes, our algorithm still manages to have a very good complexity of O(n log$\sb2\sp2$d). Chapter three presents a new decentralized algorithm in shortest path finding in a distributed and synchronous network, in particular we focus on the termination detection problem. The analysis of this algorithm shows an improved complexity over previous methods. Moreover, in chapters two and three we discuss some tradeoffs in the design of these two algorithms. Finally in chapter four we summarize our results and present some unsolved problems arising from this work. (Abstract shortened by UMI.)
To Be or Not to Be (Disabled): Identity Formations of Students with Learning Disabilities in Higher Education

description: In this study, I examined the ways in which students with LDs navigate identity formation in higher education—a meritocratic environment in which the ability to learn is valued above all else. I conducted eight semi-structured interviews with students with LDs at Brandeis University. Additionally, I interviewed two staff members at the University’s department for disability and accessibility services and observed a meeting of a student-run disability advocacy group. My findings show that students with LDs in post-secondary schools create their identities in two tiers: (1) through the navigation of their disability within the academic sector, and (2) through the negotiation of their social network in relation to their disability. From this research, it is clear that any policy changes made to address barriers against students with LDs must do so by jointly addressing both the social and medical models of disability. For LDs specifically, this means addressing the social impacts of academia as an institution and the medicalization of LDs from the medical field.

description: A Newspoll indicating a 54-46 two-party-preferred lead for Labor less than four weeks before the Victorian election is obviously bad news for the Liberal–National opposition. Other recent polling has told a similar story of steady or increased support for Labor since the last election, suggesting that opposition leader Matthew Guy lacks the momentum needed to win office on 24 November.

description: Following lesions that elevate frequency thresholds for medial forebrain bundle self-stimulation, thresholds often rapidly return toward pre-lesion levels. Why the stimulation's rewarding effect recovers has not been well understood. Small radiofrequency lesions were made through the stimulating electrode to explore some of the mechanisms that could underlie the functional recovery. By tracking post-lesion thresholds under different stimulation regimens, results of Experiment 1 indicated that the electrical stimulation itself did not promote the recovery. Experiment 2 studied the reaction of thresholds at bilateral stimulating electrodes following a unilateral lesion to determine whether a dopamine receptor supersensitivity or another distally-occurring compensation might underlie the recovery. Injection of apomorphine (0.5 mg/kg) after thresholds had returned to pre-lesion levels showed that dopamine receptor supersensitivity did not explain the recovery. As recovery took place at lesioned electrodes, thresholds at intact sites did not decrease, indicating that the recovery may not have been due to a post-lesion compensation occurring distal to the lesion site. In Experiment 3, regional post-lesion decreases in tissue resistance indicated that applying a lesion stimulus induced a change that altered resistance and accounted for threshold increases. Experiment 4 extended that investigation by comparing the effects of lesions on thresholds under constant-current and constant-voltage sources of stimulation. Post-lesion threshold increases seen under constant-current stimulation were not evident when voltage levels were not permitted to vary, indicating that when resistance was altered following a lesion, the effectiveness of the stimulation was reduced. Results of Experiment 5 showed that the refractoriness was not altered after a lesion. A sustained increase in local potential summation was noted, indicating that the lesions affected cells close to the tip of the electrode more than those further away in the stimulation field. The post-lesion recovery of thresholds may be due to local changes in ionic concentration or the occurrence of edema in the tissue around the electrode that temporarily reduces resistance before normalizing over time.

Artin groups

description: We define the 2-complete Artin complex and show that it is systolic for locally reducible Artin groups. The stabilizers of simplices in this complex are exactly the proper parabolic subgroups which are "2-complete." We use this systolicity to show that parabolic subgroups, with 2-completions that are not the whole Artin group, are weakly malnormal. This allows us to conclude that many locally reducible Artin groups are acylindrically hyperbolic.

description: Despite the availability of a wide range of tools, measuring and explaining changes in land cover and land use in tropical regions can be extremely challenging. Kerala, India, is a biodiversity hotspot with a high population density and a long history of complex agricultural land-use patterns. Some reports suggest that agriculture in Kerala, which historically is rice paddy-wetland and agroforestry-based, is on the decline. However, the evidence is often anecdotal, especially with regards to smallholding homegarden agriculture. In this study we employ mixed methods, including remote sensing, quantitative household surveys, and semi-structured interviews, to unravel the complex land-cover and land-use changes occurring in Kerala. Results indicate that, from a land-cover change perspective, agroforests are in dynamic equilibrium with other land covers, being cleared for roads and new buildings, but offset by the expansion of younger, less diverse agroforests into paddy wetlands. Yet beneath the canopy, agroforests are undergoing rapid land-use change not discernible using remote sensing. These changes include a reported decrease in the cultivation of 80% of Kerala’s primary crop species during 2003-2013, alongside a dramatic decline in chickens (from 12.5 to 2.6 per homestead on average) and cows (from 1.7 to 0.8). Over this period, no crop increased in cultivation. According to farmers, the primary drivers of this shift were declining profitability of agriculture in Kerala, labour shortages, unreliable weather, unfamiliar pests and diseases, and government policy. Despite the undeniable move away from agricultural activity in homegardens, we conclude that these ecologically and culturally important systems are not disappearing, but rather evolving to meet the needs of a less agricultural Kerala. Our research highlights the value of using mixed methods for characterizing land-use and land-cover histories in tropical regions.

description: Nanofiltration (NF) and tight ultrafiltration (tight UF) membranes are a viable treatment option for high quality drinking water production from sources with high concentrations of contaminants. To date, there is limited knowledge regarding the contribution of concentration polarization (CP) and fouling to the increase in resistance during filtration of natural organic matter (NOM) with NF and tight UF. Filtration tests were conducted with NF and tight UF membranes with molecular weight cut offs (MWCOs) of 300, 2000 and 8000 Da, and model raw waters containing different constituents of NOM. When filtering model raw waters containing high concentrations of polysaccharides (i.e., higher molecular weight NOM), the increase in resistance was dominated by fouling. When filtering model raw waters containing humic substances (i.e., lower molecular weight NOM), the increase in filtration resistance was dominated by CP. The results indicate that low MWCO membranes are better suited for NOM removal, because most of the NOM in surface waters consist mainly of humic substances, which were only effectively rejected by the lower MWCO membranes. However, when humic substances are effectively rejected, CP can become extensive, leading to a significant increase in filtration resistance by the formation of a cake/gel layer at the membrane surface. For this reason, cross-flow operation, which reduces CP, is recommended.

description: Between 2008 and 2012, undocumented immigrants who entered the United States as children acquired a new sense of collective self and status as they pushed for the passage of the Development, Relief and Education for Alien Minors (DREAM) Act. In so doing, they became a new political group known as “DREAMers.” To assess how and why undocumented immigrant students were constituted as political actors, I draw on in-depth ethnographic observations with one undocumented immigrant student social movement organization in Massachusetts, which went from a struggling group of young people to an established social movement organization in a period of two years. Defining actor constitution as a combination of collective identity and legitimacy, I argue that undocumented immigrant students became political actors as a result of: (1) biographical resources based in their life experiences of being partially incorporated and partially expulsed from society; (2) the construction of public narratives from these life experiences; (3) the acquisition of material and cultural resources in organizations; (4) opportunities and threats within the national and Massachusetts immigration policy arenas, and (5) innovative strategies and tactics that deployed identity in these political arenas. As a result, this group constructed a collective identity centered on the name “DREAMers,” and gained standing in both state and national political arenas. By bringing theories from contentious politics to the study of undocumented immigrant students, this work advances understanding of the dynamic processes that explain how this group established a collective identity and gained standing in policy-making arenas.

description: Atypical responses to direct gaze are one of the most characteristic hallmarks of autism spectrum disorder (ASD). The cause and mechanism underlying this phenomenon, however, have remained unknown. Here we investigated whether the atypical responses to eye gaze in autism spectrum disorder is dependent on the conscious perception of others’ faces. Face stimuli with direct and averted gaze were rendered invisible by interocular suppression and eye movements were recorded from participants with ASD and an age and sex matched control group. Despite complete unawareness of the stimuli, the two groups differed significantly in their eye movements to the face stimuli. In contrast to the significant positive saccadic index observed in the TD group, indicating an unconscious preference to the face with direct gaze, the ASD group had no such preference towards direct gaze and instead showed a tendency to prefer the face with averted gaze, suggesting an unconscious avoidance of eye contact. These results provide the first evidence that the atypical response to eye contact in ASD is an unconscious and involuntary response. They provide a better understanding of the mechanism of gaze avoidance in autism and might lead to new diagnostic and therapeutic interventions.
