description: In vitro pre-vascularization is one of the main vascularization strategies in the tissue engineering field. Culturing cells within a tissue-engineered construct (TEC) prior to implantation provides researchers with a greater degree of control over the fate of the cells. However, balancing the diverse range of different cell culture parameters in vitro is seldom easy and in most cases, especially in highly vascularized tissues, more than one cell type will reside within the cell culture system. Culturing multiple cell types in the same construct presents its own unique challenges and pitfalls. The following review examines endothelial-driven vascularization and evaluates the direct and indirect role other cell types have in vessel and capillary formation. The article then analyses the different parameters researchers can modulate in a co-culture system in order to design optimal tissue-engineered constructs to match desired clinical applications.
Generalised Uncertainty Principle, Remnant Mass and Singularity Problem in Black Hole Thermodynamics

description: We have derived a new Generalised Uncertainty Principle (GUP) based on certain general assumptions. This GUP is consistent with predictions from string theory. It is then used to study Schwarzschild black hole thermodynamics. Corrections to the mass-temperature relation, area law and heat capacity are obtained. We find that the evaporation process stops at a particular mass, referred as the remnant mass. This is instrumental in bypassing the well known singularity problem that occurs in a semiclassical approach.

title: On the Complexity of Collecting Items With a Maximal Sliding Agent
Creators: name: Tejada, Pedro J.
Publisher: name: Utah State University
Year: 2014

description: We study the computational complexity of collecting items inside a grid map with obstacles, using an agent that always slides to the maximal extend, until it is stopped by an obstacle. An agent could be, for example, a robot or a vehicle, while obstacles could be walls or other immovable objects, and items could be packages that need to be picked up.
This problem has very natural applications in robotics. The restricted type of motion of the agent naturally models movement on a frictionless surface, and movement of a robot with limited sensing capabilities and thus limited localization. For example, if a robot cannot determine the distance traveled once it starts moving, then it makes sense to keep moving until an obstacle is reached, even if the robot has a map of the environment.
With today’s technology it is possible to create sophisticated robots but, since the complexity and the costs of such robots are high, it is sometimes better to use simple inexpensive robots that can still solve relatively complex tasks. In fact, simple robots are quite common and usually built using simple sensors that have limited capabilities, but that are easy to use and are considerably cheaper than more sophisticated ones.
The computational complexity of numerous problems with movable objects has been extensively studied before. However, only a few of them have maximal sliding agents, and they usually do not have the goal of collecting items. We show that the problem of deciding if all the items can be collected by a maximal sliding agent can be solved efficiently when the agent is the only moving object in the map. However, we show that optimization problems such as determining the minimum number of moves required to collect all the items, and also variants in more complex environments are computationally intractable. Hence, for those problems it is better to focus on using heuristics than on finding optimal solutions.

description: The coincidence detection efficiency of the TUNL--ITEP apparatus designed for measuring half-life times of two-neutrino double-beta decay transitions to excited final states in daughter nuclei has been measured with a factor of 2.4 improved accuracy. In addition, the previous measuring time of 455 days for the study of the Mo-100 two-neutrino double-beta decay to the first excited 0+ state in Ru-100 has been increased by 450 days, and a new result (combined with the previous measurement obtained with the same apparatus) for this transition is presented: T_(1/2) = [5.5 (+1.2/-0.8) (stat) +/- 0.3 (syst)] x 10^20 y. Measured two-neutrino double-beta decay half-life times to excited states can be used to test the reliability of nuclear matrix element calculations needed for determining the effective neutrino mass from zero-neutrino double-beta decay data. We also present new limits for transitions to higher excited states in Ru-100 which, if improved, may be of interest for more exotic conjectures, like a bosonic component to neutrino statistics.

title: Improving Reuse and Maintainability of Communication Software With Conversation-Aware Aspects
Creators: name: Raza, Ali
Publisher: name: Utah State University
Year: 2014

description: Inter-process communications (IPC) are ubiquitous in today’s software systems, yet they are rarely treated as first-class programming concepts. Implementing crosscutting concerns for message-based IPC are difficult, even using aspect-oriented programming languages (AOPL) such as AspectJ. Many of these challenges are because the context of a communication-related crosscutting concern is often a conversation consisting of message sends and receives. Hence, developers typically have to implement communication protocols manually using primitive operations, such as connect, send, receive, and close. This dissertation describes an extension to AspectJ, called CommJ, with which developers can implement communication-related concerns in cohesive and loosely coupled aspects. It then presents preliminary, but encouraging results from a subsequent study that begin by defining a reuse and maintenance quality model. Subsequently the results show seven different ways in which CommJ can improve the reusability and maintainability of applications requiring network communications.

description: Cooper pairs formed by two electrons with different effective masses are common in multiband superconductors, pair density wave states, and other superconducting systems with multiple degrees of freedom. In this paper, we show that there are paramagnetic contributions to the superfluid stiffness in superconductors with different-mass Cooper pairs. This paramagnetic response is owing to the relative motion between two electrons with different mass. Additionally, we identify a particle-hole dichotomy effect related to this mass difference. We investigate the paramagnetic contributions based on the linear-response theory in two-band superconductors with interband pairings and in pair density wave states, respectively. Our results offer a different perspective of the electromagnetic superfluid stiffness in unconventional superconductors beyond the traditional BCS response.

Let $h^ω(\mathbb{N})$ be a Hilbert space of weighted sequences. It is proved that $$ \{\hat{q}(\cdot)\}\in h^ω(\mathbb{N})\Leftrightarrow\{γ_{q}(\cdot)\}\in h^ω(\mathbb{N}) \leqno(\ast) $$ if a positive, in general non-monotonic, weight $ω=\{ω(k)\}_{k\in \mathbb{N}}$ is inter-power one. In the case $q\in L^{2}(\mathbb{T})$, and $ω(k)=(1+2k)^{s}$, $s\in \mathbb{Z}_{+}$, the statement $(\ast)$ is due to Marchenko and Ostrovskii (1975).

title: Incentivizing Children's Fruit and Vegetable Consumption: Evaluation and Modification of the Food Dudes Program for Sustainable Use in U. S. Elementary Schools
Creators: name: Jones, Brooke A.
Publisher: name: Utah State University
Year: 2014

description: Researchers in the Psychology Department and the Nutrition, Dietetics, and Food Sciences Department sought to improve elementary school children’s in-school fruit and vegetable (FV) consumption. To achieve this goal, a program that has proven effective in the UK called the Food Dudes (FD) program was implemented in six local schools. Schools were assigned to either experience the traditional FD program (with prize rewards, such as pencil cases and bubbles), a modified version of the FD program (with praise rewards replacing the prize rewards), or no FD program (the control group). Students who consumed a pre-specified amount of FV each day during the intervention earned a reward according to the program’s schedule. Results showed that students in the Prize schools were consuming more FV than students in the Praise schools and the Control schools at follow-up when the intervention had been removed for six months.
While the success of the FD program with prize rewards (i.e., incentives) was encouraging, many teachers reported issues with its implementation. An incentive-based intervention may be difficult for schools to implement due to high labor and material costs, especially without outside assistance. Therefore, we aimed to reduce these costs while maintaining the use of incentives. We developed an intervention based on the principles of gamification in which students earned in-game, virtual rewards for meeting their FV consumption goals each day at school. This intervention was rated favorably by teachers and parents and showed significant increases in school-wide and individual FV consumption in two schools in Logan, UT, but long-term increases were not obtained.
Improving children’s dietary decisions, namely FV consumption, is an important goal that can positively impact future health. Sustainable, incentive-based interventions, like the school-wide gamification model developed in this project, represent a promising step toward achieving this goal.
Electrostatic spherically symmetric configurations in gravitating nonlinear electrodynamics

Year: 2009

description: We perform a study of the gravitating electrostatic spherically symmetric (G-ESS) solutions of Einstein field equations minimally coupled to generalized non-linear abelian gauge models in three space dimensions. These models are defined by lagrangian densities which are general functions of the gauge field invariants, restricted by some physical conditions of admissibility. They include the class of non-linear electrodynamics supporting ESS non-topological soliton solutions in absence of gravity. We establish that the qualitative structure of the G-ESS solutions of admissible models is fully characterized by the asymptotic and central-field behaviours of their ESS solutions in flat space (or, equivalently, by the behaviour of the lagrangian densities in vacuum and on the point of the boundary of their domain of definition, where the second gauge invariant vanishes). The structure of these G-ESS configurations for admissible models supporting divergent-energy ESS solutions in flat space is qualitatively the same as in the Reissner-Nordström case. In contrast, the G-ESS configurations of the models supporting finite-energy ESS solutions in flat space exhibit new qualitative features, which are discussed in terms of the ADM mass, the charge and the soliton energy. Most of the results concerning well known models, such as the electrodynamics of Maxwell, Born-Infeld and the Euler-Heisenberg effective lagrangian of QED, minimally coupled to gravitation, are shown to be corollaries of general statements of this analysis.

title: Barriers to Curricular Change in General Education Mathematics at a Large Public Institution
Creators: name: Jorgensen, Marcus
Publisher: name: Utah State University
Year: 2014

description: This qualitative study looked for barriers to curricular change in general education mathematics at a large public university (LPU) in the Western United States. The literature showed that a number of national organizations dealing in math education have recommended alternatives to the traditional algebra-intensive curriculum. LPU still relies predominantly on traditional College Algebra as its quantitative literacy (QL) course. With such an algebra-heavy emphasis, students may be missing more relevant and useful mathematics. In addition, the College Algebra course has a low success rate, which becomes a barrier to student retention and graduation. Interviews were conducted with 14 participants who included faculty, staff, and administrators. Analysis of the data showed 12 barriers that were grouped into four clusters: goals, control, quality, and communications. Finally, recommendations in each of the four clusters are offered for removing barriers, considering alternative curricula, and designing an intentional curriculum around QL learning outcomes.
QCD Corrections in two-Higgs-doublet extensions of the Standard Model with Minimal Flavor Violation

description: We present the QCD corrections to R_b and to the Delta B=1 effective Hamiltonian in models with a second Higgs field that couples to the quarks respecting the criterion of Minimal Flavor Violation, thus belonging either to the (1,2)_1/2 or to the (8,2)_1/2 representation of SU(3)xSU(2)xU(1). After the inclusion of the QCD corrections, the prediction for R_b becomes practically insensitive to the choice of renormalization scheme for the top mass, which for the type-I and type-II models translates in a more robust lower bound on tan(beta). The QCD-corrected determinations of Rb and BR(B->Xs gamma) are used to discuss the constraints on the couplings of a (colored) charged Higgs boson to top and bottom quarks.

description: In previous work we have shown the existence of a dynamical horizon or marginally trapped tube (MOTT) containing a given strictly stable marginally outer trapped surface (MOTS). In this paper we show some results on the global behavior of MOTTs assuming the null energy condition. In particular we show that MOTSs persist in the sense that every Cauchy surface in the future of a given Cauchy surface containing a MOTS also must contain a MOTS. We describe a situation where the evolving outermost MOTS must jump during the coalescence of two seperate MOTSs. We furthermore characterize the behavior of MOTSs in the case that the principal eigenvalue vanishes under a genericity assumption. This leads to a regularity result for the tube of outermost MOTSs under the genericity assumption. This tube is then smooth up to finitely many jump times. Finally we discuss the relation of MOTSs to singularities of a space-time.

description: In order to evaluate the suitability of graphite composite materials for use as bipolar plates in fuel cells, polypropylene (PP) was melt compounded with expanded graphite as conductive filler to form composites with different filler contents of 10–80 wt %. Electrical resistivity, thermal conductivity, and mechanical properties were measured and evaluated as a function of filler content. The electrical and thermal conductivities increased with filler content. Tensile and flexural strengths decreased with the incorporation of expanded graphite in PP. With higher graphite contents, however, both strength values remained more or less unchanged and were below the values of pure PP. Young’s-modulus and flexural modulus increased almost linearly with increasing filler content. The results of the thermogravimetric analysis confirmed the actual filler content in the composite materials. In order to evaluate the wettability and suitability for adhesive joining of graphite composites, contact angle measurements were conducted and surface tensions of composite surfaces were calculated. The results showed a significant increase in the surface tension of graphite composites with increasing filler content. Furthermore, graphite composites were adhesively joined and the strength of the joints was evaluated in the lap-shear test. Increasing filler content in the substrate material resulted in higher tensile lap-shear strength. Additionally, the influence of surface treatment (plasma and chemical) on surface tension and tensile lap-shear strength was investigated. The surface treatment led to a significant improvement of both properties.
Study to determine the need for formal speech education for teachers in training
Creators: name: Elliott, Kathleen N.
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to seek evidence as to whether formal training in oral communication is necessary for British Columbia teachers during their preparation for teaching and whether this training, when given, can have observable benefits. A further purpose was to report for teachers a study which could stimulate them to undertake further systematic investigation of the problems which have been probed and opened to inquiry in this study. The study quotes informed opinions to the effect that oral communication is of increasing importance in today's world; that this fact is recognized by leading educators; that some degree of sophistication is needed before profitable evaluation and training can take place. The study includes a survey of comments made on the speech of teachers in training in the Faculty of Education at the University of British Columbia during the year 1965-66. Two groups of teachers in training were involved: student teachers in elementary schools and student teachers in secondary schools. Three groups of commentators were involved: elementary school sponsor teachers, secondary school sponsor teachers, and Faculty of Education personnel. Three thousand specific comments were examined in order to identify areas of strength and weakness. A tentative classification was made of areas where professional help of a more or less technical kind could profitably be given as, for example, with problems of excessive speed or articulatory difficulty. A second classification was made of those areas where poor communication might indicate the need for assistance with personal problems on a deeper level. An example of this latter type might be poor projection. The thesis also describes a study using forty students in Education 416, Speech Education, during the summer session of 1966 at the University of British Columbia. The aim of this study was to point out that although many weaknesses can and do exist concurrently, strengths may be reinforced and a significant number of weaknesses eliminated through a definite programme undertaken with general and specific improvement in mind. Some conclusions resulting from the study are: i. that sponsors think some improvement in speech is needed in the case of approximately 80% of teachers in training; ii. that standards of speech can be raised through courses designed for this purpose; iii. that further research is needed with regard to: a) categorization of speech problems as being psychologically or physiologically based. b) clarification of terminology used in describing speech. Finally, this study tends to be open-ended and to regard speech as an art in human relations rather than as a science, though it may eventually lead into the new field of psycholinguistics when pursued in depth.

description: The theory of causal dynamical triangulations (CDT) attempts to define a nonperturbative theory of quantum gravity as a sum over space-time geometries. One of the ingredients of the CDT framework is a global time foliation, which also plays a central role in the quantum gravity theory recently formulated by Hořava. We show that the phase diagram of CDT bears a striking resemblance with the generic Lifshitz phase diagram appealed to by Hořava. We argue that CDT might provide a unifying nonperturbative framework for anisotropic as well as isotropic theories of quantum gravity.

description: Cold physical plasmas modulate cellular redox signaling processes, leading to the evolution of a number of clinical applications in recent years. They are a source of small reactive species, including reactive nitrogen species (RNS). Wound healing is a major application and, as its physiology involves RNS signaling, a correlation between clinical effectiveness and the activity of plasma‐derived RNS seems evident. To investigate the type and reactivity of plasma‐derived RNS in aqueous systems, a model with tyrosine as a tracer was utilized. By high‐resolution mass spectrometry, 26 different tyrosine derivatives including the physiologic nitrotyrosine were identified. The product pattern was distinctive in terms of plasma parameters, especially gas phase composition. By scavenger experiments and isotopic labelling, gaseous nitric dioxide radicals and liquid phase peroxynitrite ions were determined as dominant RNS. The presence of water molecules in the active plasma favored the generation of peroxynitrite. A pilot study, identifying RNS driven post‐translational modifications of proteins in healing human wounds after the treatment with cold plasma (kINPen), demonstrated the presence of in vitro determined chemical pathways. The plasma‐driven nitration and nitrosylation of tyrosine allows the conclusion that covalent modification of biomolecules by RNS contributes to the clinically observed impact of cold plasmas. © 2020 by the authors.

title: The Role of the Transcendent in Landscapes
Creators: name: Sonntag, Kathryn E.
Publisher: name: Utah State University
Year: 2014

description: Studies suggest the need for landscapes of contemplation is as real as ever, despite the seeming lack of spaces designed to provide the possibility of transcendent connection. Reintroducing commonly held physical attributes and characteristics of contemplative spaces, repeated through space and time, is a fundamental and necessary way to reflect renewed interest in and need for integrated ways of knowing in the landscape. This study ultimately shows that the contemplative powers of a site exist on a spectrum and reinforces the belief that every landscape architecture project can successfully incorporate some degree of contemplative design, the individual benefits of which can be great, and as a community continue to be explored. Case studies of three sites reveal that certain combinations of criteria seem to have the potential of being more effective than others. This study contributes to the overarching goal of restorative design by addressing the user need of experiencing cosmologically aligned space, the presence of which contributes to a greater sense of place and, by extension, personal identity, orientation, perspective, and purpose. This study also adds to a postmodern understanding of contemplative space, that is, the notion of an ancient framework and its contemporary application and possible contributions to the current and future betterment of individuals and communities.
title: Adolescent Self-Described Volume of Texting: Discovering Relationships with Psychosocial Development and Interpersonal Relationships
Creators: name: Cutler, Tessa
Publisher: name: Utah State University
Year: 2014

description: Researchers explored the relationship among adolescent self-reported amounts of texting and self-esteem, self-construal, autonomy, and attachment. Data were collected from a high school in an urban area in the Mountain West. Participants included 180 students (53% female). Participants were asked to self-describe their volume of texting as high, medium, or low. Participants were also asked to complete the following scales: Rosenberg Self-Esteem Scale, the Self-Construal Scale, the Case Inventory, The Adolescent Autonomy Questionnaire, and The Modified Inventory of Parent and Peer Attachment.
It is suggested that text messaging is more strongly related to self-esteem when texting is placed as the dependent variable for both males and females. Results showed that this was the pattern for each variable in question. Results also showed that Cognitive Autonomy mean scores were lower for females on four out of the five subscales of the autonomy measure. This finding was opposite from the mean scores of attachment, which revealed that females tend to have higher parental attachment scores than males.

Social consequences of contemporary financial markets and the case for a financial transaction tax
Creators: name: Willans, PS
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis considers the social effects of unprecedented growth in financial trades and speculation. The key claim is that speculative finance capital markets have caused widespread economic and social pressures. An argument is advanced that socio-economic inequalities are resultant of overleveraged, unregulated finance, and market integration over the last three decades. Pressures on civil society have arisen through governments transferring state-based funds to bail out private institutions, and stimulate economies. Socialisation of debt is used to strengthen the private sector. Central to this argument is the consideration that two economies have emerged in parallel throughout the developed world. The \real economy\" of developed nation states has been depleted by protracted global economic crises. The second \"shadow economy\" has re-emerged as a concentrated economic force with speculative daily global financial trades of over US$ 4 trillion including AU$41 billion in trades every day in Australia. The majority of trades are enabled by sophisticated high frequency trading corridors between Wall Street and the City of London. The consequences are felt worldwide. Two key questions are addressed in this thesis. First given the social consequences emanating from global financial markets and the concomitant socialisation of debt in developed economies is the introduction of a financial transaction tax a feasible progressive economic and social reform to partially ameliorate the negative effects of speculative finance capital on nation states? Second could a miniscule tax on trades recalibrate the relationships between governments and markets and provide accountability oversight and stability? This thesis concludes in the affirmative. Additionally this thesis posits an argument that transaction tax revenues in Australia the eighth largest derivatives transaction-trading nation in the world should be used specifically to strengthen national social policy commitments to homelessness and provide a targeted resource for sustainable social housing provision."

description: We present GeMS/GSAOI observations of five fast radio burst (FRB) host galaxies with sub-arcsecond localizations. We examine and quantify their spatial distributions and locations with respect to their host galaxy light distributions, finding a median host-normalized offset of 2.09 r_e and in fainter regions of the host. When combined with the FRB sample from Mannings et al. (2021), we find that FRBs are statistically distinct from Ca-rich transients in terms of light and from SGRBs and LGRBs in terms of host-normalized offset. We further find that most FRBs are in regions of elevated local stellar mass surface densities in comparison to the mean global values of their hosts. This, in combination with the combined FRB sample trace the distribution of stellar mass, points towards a possible similarity of the environments of CC-SNe and FRBs. We also find that 4/5 FRB hosts exhibit distinct spiral arm features, and the bursts originating from such hosts tend to appear on or close to the spiral structure of their hosts, with a median distance of 0.53 kpc. With many well-localized FRB detections looming on the horizon, we will be able to better characterize the properties of FRB environments relative to their host galaxies and other transient classes.

description: A nanostructured linear triblock copolymer based on styrene and butadiene with lamellar morphology is filled with multiwalled carbon nanotubes (MWCNTs) of up to 1 wt% by melt compounding. This study deals with the dispersability of the MWCNTs within the nanostructured matrix and its consequent impact on block copolymer (BCP) morphology, deformation behavior, and the electrical conductivity of composites. By adjusting the processing parameters during melt mixing, the dispersion of the MWCNTs within the BCP matrix are optimized. In this study, the morphology and glass transition temperatures (Tg) of the hard and soft phase are not significantly influenced by the incorporation of MWCNTs. However, processing-induced orientation effects of the BCP structure are reduced by the addition of MWCNT accompanied by a decrease in lamella size. The stress-strain behavior of the triblock copolymer/MWCNT composites indicate higher Young’s modulus and pronounced yield point while retaining high ductility (strain at break ~ 400%). At a MWCNT content of 1 wt%, the nanocomposites are electrically conductive, exhibiting a volume resistivity below 3 × 103 Ω·cm. Accordingly, the study offers approaches for the development of mechanically flexible functional materials while maintaining a remarkable structural property profile.
title: Are Experimentally Derived Estimates of Thermal Tolerance Useful in Interpreting Species Distribution Models
Creators: name: Sokolovska, Iva

description: Species distribution models are frequently used in ecology to predict the spatial and temporal occurrence of organisms. Direct interpretation of these models assumes that the relationships between the organisms and their environment are manifestations of causal mechanisms. However, in general, the mechanisms producing these associations have not been experimentally validated, which questions our confidence in their interpretation and application. Temperature is one of the most important factors influencing the fitness and distribution of aquatic organisms, and studying the thermal physiology of aquatic invertebrates could provide a useful approach for validating predictions of the species distribution models.
Experimental thermal tolerance studies, which assess the physiological limits to temperature, should be useful in interpreting the causal basis for species distribution model predictions. Critical Thermal Maxima experiments are frequently used to measure the thermal tolerance of ectothermic organisms. They represent the temperature at which organisms exhibit disorganized locomotor activity to the point that they lose their ability to escape conditions that will promptly lead to death. Critical Thermal Maxima experiments could, therefore, provide a useful test of the inferred mechanisms of species distribution models.
The objective of my study was to determine if Critical Thermal Maxima experiments are associated with the thermal limits inferred from species distribution models. If the models accurately describe causal relationships between predicted distributions of organisms and environmental temperatures, and if the thermal maxima are associated with the limits to organism fitness, I expected to see a strong correspondence between model-derived and experimentally-derived thermal limits. A strong correspondence between model predictions and experimentally obtained thermal maxima would both validate a physiological interpretation of the species distribution models and justify the use of Critical Thermal Maxima experiments alone in predicting species distributions and responses to climate change.

description: As an anthropological historian rather than a political scientist, my understanding of the constructs “nation”, “state”, their hybrid, “nation state”, and their ideology, “nationalism” is always historicised and draws on recent anthropological theory, as well as specific ethnohistorical research in the new states and remaining colonies of Melanesia. In terms of my work as a fellow in the Australian National University’s State, Society and Governance in Melanesia Project, this means that I do not regard “state” and “society” as opposed real entities, but as highly general concepts that describe collective human actions. I take “governance” to refer not just to “government”, but to the myriad ways in which people organize themselves, attempt to control each other, and represent what they do in the process. This paper starts with theory, in the shape of a comparative critique of certain programmatic propositions about the concepts “state”, “nation”, “nation state” and “nationalism”. I then shift to recent work, mainly by anthropologists, on the ambiguities of nation making in the highly diverse settings of postcolonial Melanesia, where “custom”/“tradition” and indigenised Christianity are brought together politically to build national consciousness and cohesion, but also elude national encompassment to fuel longstanding local particularisms and a variety of alternative or “negative” nationalisms. Christianity is doubly resistant to nationalist appropriation, since it has long been seen by Melanesians to offer membership in pan-Pacific and global moral communities transcending the often dubious legitimacy of colonial and national states. In the guise of “the Melanesian Way”, custom arguably has similar region-wide identificatory potential, but in official discourses “the Melanesian Way” is usually also Christian. The paper alludes to, but does not specifically address, the current crises of the nation state in Fiji and Solomon Islands, and concludes with specific reflections on gendered experiences of citizenship in Vanuatu.

Population energetics of two amphipod species in Marion Lake

description: The population energetics of two species of amphipods was studied at several depths in Marion Lake, BC. Hyalella azteca was abundant at a depth of 1.0 m, (mean summer standing crop, 1952 animals/m2 but became rare (75 animals/m2 at depths greater than 2.5 m. Growth rates, res- piration rates, and hence energy flow were decreased by the lower ambient temperatures of deeper water, On an annual basis, a mean standing crop of 1.1 Kcal/m2 of Hyalella assimilated 18.1 Kcal/m2 respired 14.1 Kcal/m2 and used 4.0 Kcal/m2 in production of growth, molts and eggs, Approximately 3/4 of the annual energy flow was completed between June and October, The ecological efficiency of Hyalella populations was 10, the net production efficiency, 22%, and the net population growth efficiency, 12%-13%, The mean summer density of Crangonyx remained constant with depth (about 249 animals/m2). Annual energy flow and production were not appreciably affected by lower temperatures in deeper water. On an annual basis, a mean standing crop of 0.7 Kcal/m2 assimilated 7.7 Kcal/m2 respired 6.3 Kcal/m2 and used 1.4 Kcal/m2 in production Crangonyx energy flow was fairly constant throughout the year. The ecological efficiency of Crangonyx was 8%, the net production efficiency, 17%-19%, and the population growth efficiency, 14%-15%. Annually, Hyalella populations assimilated only twice as much and produced about 3 times as much energy as did Crangonyx populations, but during the summer, Hyalella energy flow was 4 times that of Crangonyx. A synthesis of existing data on poikilotherm energetics suggests that life history phenomena are important in determining the relationship between annual population respiration and production. Also, annual production and assimilation were found to be closely related to the mean standing crop of various organisms.
