Assessment of a data-limited, multi-species shark fishery in the Great Barrier Reef Marine Park and south-east Queensland

The status of five species of commercially exploited sharks within the Great Barrier Reef Marine Park (GBRMP) and south-east Queensland was assessed using a data-limited approach. Annual harvest rate, U, estimated empirically from tagging between 2011 and 2013, was compared with an analytically-derived proxy for optimal equilibrium harvest rate, UMSY Lim. Median estimates of U for three principal retained species, Australian blacktip shark, Carcharhinus tilstoni, spot-tail shark, Carcharhinus sorrah, and spinner shark, Carcharhinus brevipinna, were 0.10, 0.06 and 0.07 year-1, respectively. Median U for two retained, non-target species, pigeye shark, Carcharhinus amboinensis and Australian sharpnose shark, Rhizoprionodon taylori, were 0.27 and 0.01 year-1, respectively. For all species except the Australian blacktip the median ratio of U/UMSY Lim was <1. The high vulnerability of this species to fishing combined with life history characteristics meant UMSY Lim was low (0.04-0.07 year-1) and that U/UMSY Lim was likely to be > 1. Harvest of the Australian blacktip shark above UMSY could place this species at a greater risk of localised depletion in parts of the GBRMP. Results of the study indicated that much higher catches, and presumably higher U, during the early 2000s were likely unsustainable. The unexpectedly high level of U on the pigeye shark indicated that output-based management controls may not have been effective in reducing harvest levels on all species, particularly those caught incidentally by other fishing sectors including the recreational sector. © 2016 Elsevier B.V.

National Myths and Heroes: a Case of Vytautas the Great in Lithuania

The main focus of the thesis concentrates on nationalism and how it is expressed through national myth and a hero. As a case study for Lithuania the cult of Vytautas the Great is used. Theses present how the myth of Vytautas the Great was created and why particularly the Grand duke became a national symbol. It also examines how main nationalism theories are reflected in this case. The main purpose of the thesis is to find out how this myth matches the needs of the current Lithuanian society – the last year schoolchildren (eighteen – nineteen years old) in particular. The main method used in the empirical part of the thesis is qualitative analysis: primary source material was gathered by using semi – structured interviews and the results were analyzed by employing thematic analysis. The theoretical part of the study presents the core nationalism and ethnic identity theories and describes the concepts of national myth and hero as well as their connection and influence for the society and Lithuanians precisely. In this study nationalism is understood as a phenomenon that holds a nation together and is reflected via certain national symbols such as national myths and heroes by forming a national identity the meaning of which is different for each generation. The analysis of the results in this study has showed that the idea of Vytautas the Great as a national hero – symbol, created in the interwar Lithuanian society has lost its significance for the current schoolchildren and has been replaced by other images. However, at the same time the Grand duke is still perceived as an embodiment of the main national Lithuanian virtues.

SYSTEM DYNAMICS MODELING AS A QUANTITATIVE-QUALITATIVE FRAMEWORK FOR SUSTAINABLE WATER RESOURCES MANAGEMENT: INSIGHTS FOR WATER QUALITY POLICY IN THE GREAT LAKES REGION

Early water resources modeling efforts were aimed mostly at representing hydrologic processes, but the need for interdisciplinary studies has led to increasing complexity and integration of environmental, social, and economic functions. The gradual shift from merely employing engineering-based simulation models to applying more holistic frameworks is an indicator of promising changes in the traditional paradigm for the application of water resources models, supporting more sustainable management decisions. This dissertation contributes to application of a quantitative-qualitative framework for sustainable water resources management using system dynamics simulation, as well as environmental systems analysis techniques to provide insights for water quality management in the Great Lakes basin. The traditional linear thinking paradigm lacks the mental and organizational framework for sustainable development trajectories, and may lead to quick-fix solutions that fail to address key drivers of water resources problems. To facilitate holistic analysis of water resources systems, systems thinking seeks to understand interactions among the subsystems. System dynamics provides a suitable framework for operationalizing systems thinking and its application to water resources problems by offering useful qualitative tools such as causal loop diagrams (CLD), stock-and-flow diagrams (SFD), and system archetypes. The approach provides a high-level quantitative-qualitative modeling framework for "big-picture" understanding of water resources systems, stakeholder participation, policy analysis, and strategic decision making. While quantitative modeling using extensive computer simulations and optimization is still very important and needed for policy screening, qualitative system dynamics models can improve understanding of general trends and the root causes of problems, and thus promote sustainable water resources decision making. Within the system dynamics framework, a growth and underinvestment (G&U) system archetype governing Lake Allegan's eutrophication problem was hypothesized to explain the system's problematic behavior and identify policy leverage points for mitigation. A system dynamics simulation model was developed to characterize the lake's recovery from its hypereutrophic state and assess a number of proposed total maximum daily load (TMDL) reduction policies, including phosphorus load reductions from point sources (PS) and non-point sources (NPS). It was shown that, for a TMDL plan to be effective, it should be considered a component of a continuous sustainability process, which considers the functionality of dynamic feedback relationships between socio-economic growth, land use change, and environmental conditions. Furthermore, a high-level simulation-optimization framework was developed to guide watershed scale BMP implementation in the Kalamazoo watershed. Agricultural BMPs should be given priority in the watershed in order to facilitate cost-efficient attainment of the Lake Allegan's TP concentration target. However, without adequate support policies, agricultural BMP implementation may adversely affect the agricultural producers. Results from a case study of the Maumee River basin show that coordinated BMP implementation across upstream and downstream watersheds can significantly improve cost efficiency of TP load abatement.

Pesky Pests of the Great Lakes State: Is Public Participation Influenced by Geographic Differences?

In Michigan, environmental issues, such as invasive species, are not geographically constrained, affecting citizens throughout the state. Regulations and management plans organized by scientists and officials are intended to address issues statewide, but these policies may not adequately tackle the threat from invasive species as it impacts different parts of the state at different times. Participation and contributions from citizens can offer insight into the impacts and changes non-native species have on the local ecosystem. However, chances to participate and contribute may be influenced by geographic location in the state. To understand if this was the case, this research studied publicly available documents and completed participant observations and semistructured interviews with participants, leaders, and officials included in invasive species management. Between the two study locations, Metro Detroit and the Western Upper Peninsula of Michigan, locational differences had some impact on opportunities to contribute to invasive species management. Population and the differences in the type of advertising used to alert citizens about events influenced access to participation opportunities. This research also revealed that this public policy issue lacks public involvement and contributions. Between the two locations, more involvement opportunities and organizations were present in Metro Detroit. However, it was the organizations themselves and their limited political involvement, and not geographic location, which had a greater impact on citizens' lack of participation in invasive species management.

Development of measurement and modeling techniques to quantify atmospheric deposition of persistent, bioaccumulative and toxic chemicals in the Great Lakes

Measurement and modeling techniques were developed to improve over-water gaseous air-water exchange measurements for persistent bioaccumulative and toxic chemicals (PBTs). Analytical methods were applied to atmospheric measurements of hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Additionally, the sampling and analytical methods are well suited to study semivolatile organic compounds (SOCs) in air with applications related to secondary organic aerosol formation, urban, and indoor air quality. A novel gas-phase cleanup method is described for use with thermal desorption methods for analysis of atmospheric SOCs using multicapillary denuders. The cleanup selectively removed hydrogen-bonding chemicals from samples, including much of the background matrix of oxidized organic compounds in ambient air, and thereby improved precision and method detection limits for nonpolar analytes. A model is presented that predicts gas collection efficiency and particle collection artifact for SOCs in multicapillary denuders using polydimethylsiloxane (PDMS) sorbent. An approach is presented to estimate the equilibrium PDMS-gas partition coefficient (Kpdms) from an Abraham solvation parameter model for any SOC. A high flow rate (300 L min-1) multicapillary denuder was designed for measurement of trace atmospheric SOCs. Overall method precision and detection limits were determined using field duplicates and compared to the conventional high-volume sampler method. The high-flow denuder is an alternative to high-volume or passive samplers when separation of gas and particle-associated SOCs upstream of a filter and short sample collection time are advantageous. A Lagrangian internal boundary layer transport exchange (IBLTE) Model is described. The model predicts the near-surface variation in several quantities with fetch in coastal, offshore flow: 1) modification in potential temperature and gas mixing ratio, 2) surface fluxes of sensible heat, water vapor, and trace gases using the NOAA COARE Bulk Algorithm and Gas Transfer Model, 3) vertical gradients in potential temperature and mixing ratio. The model was applied to interpret micrometeorological measurements of air-water exchange flux of HCB and several PCB congeners in Lake Superior. The IBLTE Model can be applied to any scalar, including water vapor, carbon dioxide, dimethyl sulfide, and other scalar quantities of interest with respect to hydrology, climate, and ecosystem science.

The Great Escape: A Modern Charismatic Movement within the Presbyterian Church

The present thesis examines the relationship between Youth Conference Ministries (YCM) and the Presbyterian Church. YCM is a charismatic organization that organizes youth retreats for students in middle school and high school, with the goal of charismatically educating the youth of America. The focus of this thesis is on the Great Escape Southwind, a middle school retreat that caters to the southern portion of United States. My thesis first traces the biblical and historical underpinnings of charismatic Christianity. Next it provides an ethnographic case study of the Great Escape, focusing on its ability to foster spiritual growth of students through an enthusiastic response to the Holy Spirit. Finally it examines the relationship between YCM and the Presbyteries that populate its retreats. Overall this thesis shows how YCM provides a charismatic service to the local Presbyterian Churches, allowing for its adolescent parishioners to remain enthusiastically active as they progress towards adulthood.

Lions and Roses: An Interpretive History of Israeli-Iranian Relations

This multi-disciplinary research project explores the religious and cultural foundations within the “master commemorative narratives” that frame Israeli and Iranian political discourse. In articulating their grievances against one another, Israeli and Iranian leaders express the tensions between religion, nationalism, and modernity in their own societies. The theoretical and methodological approach of this dissertation is constructivist-interpretivist. The concept of “master commemorative narratives” is adapted from Yael Zerubavel’s study of ritualized remembrance in Israeli political culture, and applied to both Israeli and Iranian foreign policy. Israel’s master commemorative narrative draws heavily upon the language of the Hebrew Bible, situating foreign policy discourse within a paradigm of covenantal patrimony, exile, and return, despite the unrelenting hostility of eternal enemies and “the nations.” Iran’s master commemorative narrative expresses Iranian suspicion of foreign encroachment and interference, and of the internal corruption that they engender, sacralizing resistance to the forces of evil in the figurative language and myths of pre-Islamic tradition and of Shi‘a Islam. Using a constructivist-interpretive methodological approach, this research offers a unique interpretive analysis of the parallels between these narratives, where they intersect, and where they come into conflict. It highlights both the broad appeal and the diverse challenges to the components of these “master” narratives within Israeli and Iranian politics and society. The conclusion of this study explains the ways in which the recognition of religious and cultural conflicts through the optic of master commemorative narratives can complement the perspectives of other theoretical approaches and challenge the conventions of Security Studies. It also suggests some of the potential practical applications of this research in devising more effective international diplomacy.

The genus Deretrema Linton, 1910 (Digenea : Zoogonidae) from southern Great Barrier Reef fishes, with a description of Deretrema woolcockae n. sp.

Two species of Deretrema (Zoogonidae) are reported from labrid fishes from the Great Barrier Reef. D. nahaense Yamaguti, 1942 is recorded from the gall-bladders of the labrids Thalassoma hardwicke (Bennett), T. jansenii (Bleeker), T. lunare (Linnaeus) and T. lutescens (Lay & Bennett). This species is recognised, despite having been formerly synonymised with D. pacificum Yamaguti, 1942. In addition to morphological distinction, D. nahaense appears to have strict host-specificity for the genus Thalassoma. D. woolcockae n.sp. is described from the gall-bladder of Hemigymnus fasciatus (Bloch). The new species is close to D. acutum Pritchard, 1963 and D. plotosi Yamaguti, 1940, but differs slightly in the distribution of the vitelline follicles, the sucker-ratio and the position of the cirrus-sac. In addition, this species also appears to have a distinct host-specificity, being restricted to one labrid species.

Changes in heron and egret populations on the Laurentian Great Lakes and connecting channels, 1977-2009

Canadian and U.S. federal wildlife agencies completed four decadal surveys, spanning the years 1977 to 2009, to census colonial waterbirds breeding on the Great Lakes and adjoining bodies of water. In this paper, we reports abundance, distribution, and general population trends of three species: Black-crowned Night-Heron (Nycticorax nycticorax), Great Egret (Ardea alba), and Great Blue Heron (Ardea herodias). Estimates of nest numbers ranged from approximately 4000-6100 for the Black-crowned Night-Heron, 250-1900 for the Great Egret, and 3800-6400 for the Great Blue Heron. Average annual rates of change in nest numbers between the first (1977) and fourth (2008) census were −1% for the Black-crowned Night-Heron, +23% for the Great Egret, and −0.27% for the Great Blue Heron. Across the 30-year census, Black-crowned Night-Heron estimates decreased in U.S. (−57%) but increased (+18%) in Canadian waters, Great Egret nests increased 1381% in Canadian waters with a smaller, but still substantial increase in the number of nests at U.S. colonies (+613%), and Great Blue Heron numbers increased 148% in Canadian waters and 713% in U.S. waters. Although a single factor cannot be clearly linked to changes observed in each species’ distribution, hydrological variation, habitat succession, nest competition with Double-crested Cormorants (Phalacrocorax auritus), and land use changes likely all contributed. Management activities should support both breeding and foraging conditions including restoration of early successional habitats and anticipate continued northward expansions in the distributions of these waterbirds.

The re-identification of great bustard (Otis tarda) from Fishbourne Roman Palace, Chichester, West Sussex, as common crane (Grus grus)

This paper details the results of recent reanalysis of the animal remains from the 1960s excavations at Fishbourne Roman Palace, West Sussex. It argues that specimens originally identified as belonging to the great bustard are, in fact, misidentified remains of common crane. This discovery has important connotations. First, these findings need to be reported so that the avian archaeological record can be updated to avoid future syntheses of Romano-British faunal remains incorrectly including great bustard. Secondly, interpretations of the zooarchaeological remains at Fishbourne Palace will alter, due to the differing ecological histories of bustards and cranes.

Economic recovery from the Argentine great depression : institutions, expectations, and the change of macroeconomic regime

This work explores how Argentina overcame the Great Depression and asks whether active macroeconomic interventions made any contribution to the recovery. In particular, we study Argentine macroeconomic policy as it deviated from gold-standard orthodoxy after the final suspension of convertibility in 1929. As elsewhere, fiscal policy in Argentina was conservative, and had little power to smooth output. Monetary policy became heterodox after 1929. The first and most important stage of institutional change took place with the switch from a metallic monetary regime to a fiduciary regime in 1931; the Caja de Conversión (Conversion Office, a currency board) began rediscounting as a means to sterilize gold outflows and avoid deflationary pressures, thus breaking from orthodox "mIes of the game." However, the actual injections of liquidity were small' and were not enough to fully offset the incipient monetary contractions: the "Keynes" effect was weak or negative. Rather, recovery derived from changes in beliefs and expectations surrounding the shift in the monetary and exchange-rate regime,and the delinking of gold flows and the money base. Agents perceivod a new regime, as shown by the path of consumption, investment, and estimated ex ante real interest rates: the "Mundell" effect was dominant. Notably, this change of regime predated a later, and supposedly more significant, stage of institutional reform, namely the creation of the central bank in 1935. Still, the extent of intervention was weak, and insufficient to fully offset externaI shocks to prices and money. Argentine macropolicy was heterodox in terms of the change of regime, but still conservative in terms of the tentative scope of the measures taken .
