Spatio-temporal Ecological and Evolutionary Dynamics in Natural Butterfly Populations (2013 Field Season)
Authors: Gompert Zachariah , Lucas Lauren
Published: July 2020

The study of evolution in natural populations has advanced our understanding of the origin and maintenance of biological diversity. For example, long term studies of wild populations indicate that natural selection can cause rapid and dramatic changes in traits, but that in some cases these evolutionary changes are quickly reversed when periodic variation in weather patterns or the biotic environment cause the optimal trait value to change (e.g., Reznick et al. 1997, Grant and Grant 2002). In fact, spatial and temporal variation in the strength and nature of natural selection could explain the high levels of genetic variation found in many natural populations (Gillespie 1994, Siepielski et al. 2009). Long term studies of evolution in the wild could also be informative for biodiversity conservation and resource management, because, for example, data on short term evolutionary responses to annual fluctuations in temperature or rainfall could be used to predict longer term evolution in response to directional climate change. Most previous research on evolution in the wild has considered one or a few observable traits or genes (Kapan 2001, Grant and Grant 2002, Barrett et al. 2008). We believe that more general conclusions regarding the rate and causes of evolutionary change in the wild and selectionâs contribution to the maintenance of genetic variation could be obtained by studying genome-wide molecular evolution in a suite of natural populations. Thus, we have begun a long term study of genome-wide molecular evolution in a series of natural butterfly populations in the Greater Yellowstone Area (GYA). This study will allow us to quantify the contribution of environment-dependent natural selection to evolution in these butterfly populations and determine whether selection consistently favors the same alleles across space and through time.
Nutrient Limitation and Uptake Rates in Streams and Rivers of the Greater Yellowstone Ecosystem
Authors: Tank Jennifer , Reisinger Alexander
Published: July 2020

Nutrient pollution of aquatic ecosystems is a growing concern as the influence of human activities continues to increase on the landscape. Headwater streams have long been shown to process nutrients via the biofilm community growing on the bottom of streams. The growth and activity of these biofilms is often limited by the availability of nitrogen (N), phosphorus (P), or co-limited by both N and P. Although small stream nutrient dynamics are relatively well understood, comparatively little is known about larger, non-wadeable rivers. Biofilms on the river bottom are likely still nutrient limited, but there becomes an increased potential for light limitation as rivers increase in depth. In addition to biofilms on the bottom of rivers, free-living microbial communities suspended in the water column also occur in rivers and process nutrients - a component of nutrient processing largely ignored in streams. In summer 2013 we worked in streams and rivers of the Greater Yellowstone Area (GYA) to establish the nutrient limitation status of minimally-impacted rivers, as well as the role of the water column in processing nutrients as streams increase in size. For both the nutrient limitation and water column uptake studies, we are using the GYA sites in addition to systems from other regions of the US to establish what controls the various aspects of nutrient dynamics in rivers. Our results from the GYA, in addition to Midwest and Southwest US rivers, will provide water quality managers with new strategies for improving water quality downstream, and clarify mechanisms controlling nutrient retention in rivers.
Effects of Climate and Biotic Factors on Life History Characteristics and Vital Rates of Yellowstone Cutthroat Trout in Spread Creek, Wyoming
Authors: Uthe Patrick , Al-Chokhachy Robert
Published: July 2020

The Upper Snake River represents one of the largest remaining strongholds of Yellowstone cutthroat across its native range. Understanding the effects of restoration activities and the diversity of life-history patterns and factors influencing such patterns remains paramount for long-term conservation strategies. In 2011, we initiated a project to quantify the success of the removal of a historic barrier on Spread Creek and to evaluate the relative influence of different climate attributes on native Yellowstone cutthroat trout and non-native brook trout behavior and fitness. Our results to date have demonstrated the partial success of the dam removal with large, fluvial Yellowstone cutthroat trout migrating up Spread Creek to spawn, thus reconnecting this population to the greater Snake River metapopulation. Early indications from mark-recapture data demonstrate considerable differences in life-history and demographic patterns across tributaries within the Spread Creek drainage. Our results highlight the diversity of life-history patterns of resident and fluvial Yellowstone cutthroat trout with considerable differences in seasonal and annual growth rates and behavior across populations. Continuing to understand the factors influencing such patterns will provide a template for prioritizing restoration activities in the context of future challenges to conservation (e.g., climate change).
Dendrochronological Assessment of Whitebark Pine Response to Past Climate Change: Implications for a Threatened Species in Grand Teton National Park
Authors: McLauchlan Kendra , Kelly Kyleen
Published: July 2020

One of the keystone tree species in subalpine forests of the western United States â whitebark pine (Pinus albicaulis, hereafter whitebark pine) â is experiencing a significant mortality event (Millar et al. 2012). Whitebark pine occupies a relatively restricted range in the high-elevation ecosystems in the northern Rockies and its future is uncertain. The current decline of whitebark pine populations has been attributed to pine beetle infestations, blister rust infections, anthropogenic fire suppression, and climate change (Millar et al. 2012). Despite the knowledge that whitebark pine is severely threatened by multiple stressors, little is known about the historic capacity of this species to handle these stressors. More specifically, it is unknown how whitebark pine has dealt with past climatic variability, particularly variation in the type of precipitation (rain vs. snow) available for soil moisture, and how differences in quantity of precipitation have influenced the establishment and growth of modern stands. We propose to study the past responses of whitebark pine to paleoclimatic conditions, which would be useful to park ecologists in developing new conservation and regeneration plans to prevent the extinction of this already severely threatened high-elevation resource. The purpose of this study is to determine in great temporal and spatial detail the demographics of the current stand of whitebark pine trees in the watershed surrounding an unnamed, high-altitude pond (known informally as Whitebark Pine Moraine Pond) located approximately 3.06 miles NW of Jenny Lake in Grand Teton National Park (GTNP). The main objectives of this study were: 1.) To obtain the precise GPS locations of the current stand of whitebark pine trees in the watershed to generate a GIS map detailing their locations. 2.) To obtain increment cores of a subset of the trees in the watershed to estimate age and date of establishment for the current stand of whitebark pines, with particular attention to fire history. 3.) To analyze ring widths from core samples to identify climatic indicators that may influence the regeneration and survival of whitebark pine.

Field Research & Conservation emphasizes long-term field research experiences, examines ecosystem processes, and investigates the evolution of American perspectives about nature. Our time spent at the UW-NPS research station is divided between pursuing behavioral ecology research and exploring Grand Teton National Park and the surrounding area. These experiences help students gain understanding of how the region was shaped by geological, biological, and political processes that have been influenced by Americaâs evolving conservation ethic. After the summer field experience, my students assist in data analysis and the development of a poster project. We present our findings at the Phi Sigma Research Symposium at Illinois State University and the St. Louis Ecology, Evolution, and Conservation Retreat at Southern Illinois University Edwardsville.

Spiders Revisited: Retracing the Steps of Herbert and Lorna Levi's Historic Invertebrate Surveys of the Jackson Hole Region of Wyoming
Authors: Kariko Sarah , Rossman Daniel
Published: July 2020

In 1950, Herbert and Lorna Levi collected invertebrates in Yellowstone and Grand Teton National Parks and other localities in the region. Sixty-five years later and looking towards the centennial of the National Park Service, a preliminary reassessment of the biodiversity of spiders was conducted in a subset of localities that were collected by the Levis. Specimens have been collected and are in the process of being identified. Comparison of this new collection with the historical records is currently underway. As the arts have played a crucial role in the history of national parks, we are exploring how to partner art and science to share the beauty and wonder of spiders based on our fieldwork in celebration of the upcoming National Park Service centennial.
The 2015 Table Mountain Ice Patch Project: Grand Teton National Park, Teton County, WY
Authors: Peterson Marcia
Published: July 2020

Ice patches are permanent snow and ice fields that survive through the summer months but are not massive enough to become glaciers. Prehistorically, people used ice patches for hunting, and organic hunting-related artifacts have been recovered from them. As a result of global warming, the ice patches are melting and exposing artifacts and other material that were preserved under the ice for millennia. Once exposed, the organic artifacts deteriorate. Recovery of these artifacts before they are lost is critical to understanding the paleoecology of and the prehistoric people who used the Teton high elevations (Lee 2009, 2015). In 2015, I surveyed ice patches on Table Mountain pursuant to Section 110 of the National Historic Preservation Act. The work was conducted under OWSA permits 15-GRTE-01 and GRTE-2015-SCI-0040 and was partially funded by the UW-NPS Research Station. One historic archaeological site (48TE1983) was documented and four paleobiological specimens were collected.
Boom and bust of an aquatic invasive species? Population monitoring of the New Zealand mudsnail (Potamopyrgus antipodarum) and interactions with native species in Polecat Creek, WY
Authors: Greenwood Daniel , Krist Amy C.
Published: July 2020

The invasive New Zealand mudsnail (Potamopyrgus antipodarum) has been found to reach densities exceeding 500,000 individuals/m2 in Polecat Creek, located in the Greater Yellowstone Ecosystem in Wyoming. The biomass of P. antipodarum in Polecat Creek has declined in recent years, suggesting the population “boomed and busted”; the population was booming in 2000-2001, but in 2011 the biomass had decreased by ~93%, suggesting a “bust” period for P. antipodarum. Native, net-spinning caddisflies (Hydropsyche spp.) have increased dramatically in biomass from 2001-2010, which may indicate that some native macroinvertebrates have increased in biomass due to release of suppression by P. antipodarum. I collected macroinvertebrate core samples in Polecat Creek to monitor any changes in macroinvertebrate biomass and performed field experiments to determine a possible mechanism by which P. antipodarum may have suppressed Hydropsyche caddisfly populations. I allowed Hydropsyche larvae to establish and build nets on tiles within experimental chambers in Polecat Creek and added “boom” and “bust” densities of P. antipodarum to chambers. Preliminary results showed no significant difference between the number of nets present in control chambers excluding P. antipodarum and chambers containing “boom” and “bust” densities of P. antipodarum. This suggests that P. antipodarum do not actively destroy nets, but may interfere with feeding by clustering upon nets.

Factors influencing American Pika (Ochotona princeps) distributions in the Beartooth Mountains and implications of a warming climate
Authors: Tonkyn David , Hanley Kaitlyn , Quakenbush Katie
Published: July 2020

Over the next century, temperatures are expected to rise by 1-4°C in the Greater Yellowstone Region. This will force alpine species such as the American pika (Ochotona princeps) to compensate, shift in distribution, or disappear. If pika are limited by temperatures, they may disappear from warmer, lower elevation southwest-facing sites and find refuge in cooler, higher elevation northeast-facing sites. However, populations have been found across a range of elevations, suggesting they are instead limited by food or a need for large talus slopes. We explored these possibilities in the Beartooth Mountains, near Yellowstone, by surveying 31 pika populations and asking whether pika density varied with elevation, food availability, or aspect, all related to temperatures, or with talus area, which is not. Pika density was estimated by latrine density, which ranged from 14.6 to 167.4 per ha and declined slightly with elevation but was unrelated to vegetation. From a preliminary analysis of 61 sites, we estimated an occupancy probability of 0.89, with occupancy most strongly related to talus area. We will test and refine these results by predicting the locations of additional colonies, and by incorporating microclimate data into an ecophysiological model of temperature dependence in pika, with the long-term goal of predicting the fate of pika under a warming climate.

A growing body of evidence suggests that traffic noise negatively affects wildlife. Protected natural areas are not free from noise exposure, both external to and within park boundaries. Natural soundscapes are important in many aspects of animal life histories, for increasing positive visitor experiences, and for providing psychological ecosystem services. To examine the use of signs as an effective traffic noise mitigation strategy, we experimentally altered speed limits from 45 mph to 25 mph, with additional educational signage, along the Oxbow Bend traffic corridor in Grand Teton National Park, USA. We continuously recorded sound levels between alternating week-long blocks while conducting avian point counts at each station. We detected 2,217 individuals of 48 species across all stations throughout the study. To assess visitor experiences with the soundscapes and visitor attitudes towards sign use and management strategies, we conducted stated-choice intercept surveys along a park turnout within the experimental corridor. We administered 471 surveys at an 82% response rate. Future data will evaluate impacts of traffic noise on avian abundance and distributions, visitor attitudes towards mitigation strategies, and the potential coupling between human and natural systems via the soundscape.

Polarization-sensitive transfer matrix modeling for displacement measuring interferometry
Authors: Bridges Angus , Yacoot Andrew , Kissinger Thomas , Tatam Ralph P.
Published: July 2020

The use of polarizing optics for both beam steering and phase measurement applications in displacement measuring interferometer designs is almost universal. Interferometer designs that employ polarizing optics in this manner are particularly sensitive to the effects of unwanted optical cavities that form within the optics due to polarization leakage and back reflections from material interfaces. Modeling techniques commonly employed in the design of such interferometers are poorly suited to the analysis of multiple passes through polarizing optics. A technique, along with an accompanying software implementation, is presented here that is capable of modeling the propagation of monochromatic plane waves through an arbitrary network of linear planar optical components.

We report a full experimental comparison study on the injection of a Ti:Sa multi-terawatt amplifier chain with a standard 15 fs Ti:Sa oscillator and 35 fs frequency-doubled fiber oscillator. The study highlights that the Ti:Sa oscillator, with high performance in terms of pulse duration and spectral width, can be replaced by the frequency-doubled fiber oscillator to seed Ti:Sa amplifier chains almost without any compromise on the output pulse duration and picosecond contrast. Finally, we demonstrate for the first time to our knowledge a 30 TW and 33 fs Ti:Sa amplifier injected by a fiber oscillator.
Foundry-compatible thin film lithium niobate modulator with RF electrodes buried inside the silicon oxide layer of the SOI wafer
Authors: Safian Reza , Teng Min , Zhuang Leimeng , Chakravarty Swapnajit
Published: July 2020

Ever-increasing complexity of communication systems demands the co-integration of electronics and photonics. But there are still some challenges associated with the integration of thin film lithium niobate (TFLN) electro-optic modulators with the standard and well-established silicon photonics. Current TFLN platforms are mostly not compatible with the silicon photonics foundry process due to the choice of substrate or complicated fabrication requirements, including silicon substrate removal and formation of radio-frequency (RF) electrodes on the top of the TFLN. Here, we report on a platform where all the optical and RF waveguiding structures are fabricated first, and then the TFLN is bonded on top of the silicon photonic chip as the only additional step. Hence, the need for substrate removal is eliminated, and except for the last step of TFLN bonding, its fabrication process is silicon foundry compatible and much more straightforward compared to other fabrication methods.

Published: July 2020

In this Letter, we investigate the resolution of two-photon polymerization (2PP) with an amplified mode-locked external cavity diode laser with adjustable pulse length and a high repetition rate. The experimental results are analyzed with a newly developed 2PP model. Even with low pulse peak intensity, the produced structural dimensions are comparable to those generated by traditional 2PP laser sources. Thus, we show that a compact monolithic picosecond laser diode without amplification and with a repetition rate in the GHz regime can also be applied for 2PP. These results show the high application potential of compact mode-locked diode lasers for low-cost and compact 2PP systems.

Icons of colonial injustice: From photographs to public art
Authors: Palmer Daniel
Published: July 2020

In the archive of Australian photography, few images point to the gross injustices experienced by Indigenous Australians more forcefully than a 1906 photograph depicting a group of Aboriginal people in neck chains. More recently, few images point to Indigenous self-empowerment more powerfully than a 1993 press photograph of footballer Nicky Winmar lifting his jumper to point proudly to his dark skin. This article explores the extraordinary legacy of these two images and specifically their translation into prominent contemporary public artworks – respectively, a street mural in inner Melbourne and a statue located outside a major football stadium in Perth. I argue that by drawing on, but also extending, the original content of the images, these public translations of the photographs, and the story of their coming into being, become another chapter in the lives of the images. Moreover, in the shift from print to pavement, they transform public spaces into sites of public pedagogy.
Who is afraid of public space? Public art in a contested, secured and surveilled city
Authors: McQuilten Grace
Published: July 2020

In the wake of multiple global crises, fears of terrorism, rising nationalistic sentiments globally and the pervasive impacts of gender-based violence in public spaces, contemporary urban cities are permeated with surveillance, anxiety, fear and division. In this context, what role can (and should) public art be playing? This article explores this question in the context of Melbourne, a major metropolitan centre in Australia, which has been ruptured by the multiplying effects of highly publicized episodes of street violence, isolated terrorist attacks, high-profile murders and politically driven narratives about youth gangs. Looking at the work of female artists Maryann Talia Pau, Amy Spiers and Catherine Ryan, and artists from African Australian communities including Ez Deng, Atong Atem and Asia Hassan, the article addresses questions about agency and marginalization for artists working in public space, and considers how marginalized community groups may face barriers to creating artworks that engage directly in mainstream public spaces.

Não é um tratamento completo do título aristotélico, mas as suas nove disputas formam um breve compêndio no qual é possível ver a relevância da Summa theologiae de Tomás de Aquino. Tal como aconteceu com os outros títulos de Coimbra, a Ethica espalhou-se rapidamente pelas Universidades e Colégios europeus, e chegou aos territórios sul-americanos e à China. O presente volume, o segundo volume da série que o IUC está actualmente a publicar, introduz o texto de Coimbra e fornece uma edição moderna do latim original com uma tradução portuguesa.
Mapping Understory Invasive Plants in Urban Forests with Spectral and Temporal Unmixing of Landsat Imagery
Authors: Singh Kunwar K. , Gray Josh
Published: July 2020

Successful eradication and management of invasive plants require frequent and accurate maps. Detection of invasive plants is difficult at moderate resolution because target species are often located in the forest understory among other vegetation types, and so produce mixed spectral
signatures. Spectral unmixing approaches can help to decompose these spectral mixtures; however, they are typically applied to only one or a few images, and thus neglect phenological variability that may improve invasive species discrimination. We compared two approaches to multiple endmember
spectral mixture analysis for detecting Ligustrum sinense in the southeastern United States: the use of temporal signatures of endmembers from full and select-date normalized difference vegetation index time series, and conventional spectral unmixing using a single image date. Our results
suggest that using temporal signatures from all available imagery may be a good choice, with minimal impact to achievable accuracy, if a priori information on phenological differences between endmembers is unavailable, or imagery for periods of high phenological difference are unavailable.

Analysis on the influencing factors of spatial correlation of haze pollution in North China
Authors: Wang Linshan , Liu Chuanming , Xi Yang
Published: July 2020

Based on the AQI daily data of Northern China from January 1, 2016 to December 31, 2018, this paper uses nonlinear Granger causality test technology to identify the spatial correlation of haze pollution, and from the perspective of relational data, adopt Quadratic Assignment Procedure (QAP) to investigate the influencing factors of the spatial correlation of haze pollution in northern China. This study finds that：(1) QAP correlation analysis shows that geographical distance matrix, difference in the development level of the tertiary industry and difference in the green space area of urban construction are correlated with haze pollution. (2) QAP regression analysis results show that geographic distance matrix, economic development level and environmental regulation level can explain why the adjustment factor of spatial correlation of haze pollution is 2.6%. The influence of geographical distance matrix on the spatial correlation network of haze pollution within the range of 0~300km has passed the significance test, which indicates that haze pollution has broken through the geographical proximity effect, and more distant cities also have spatial correlation of haze pollution.

CHUKWUMA NZEOGWU IN THE THROES OF CONTEMPORARY NIGERIAN HISTORY
Authors: Wambu Chiemela , Ecoma Chinyere
Published: July 2020

For the greater part of its existence as a sovereign state, Nigeria has witnessed more years of military than civilian rule. An excursion into this very important aspect of our national history must, of necessity, interrogate the circumstances and dramatis personae that led to the military’s intervention in national politics. One name that has never escaped the scrutiny in this effort is that of Major Chukwuma Kaduna Nzeogwu. Though a posthumous research, the intention of this paper is to attempt a reappraisal of the often ignored, misinterpreted and maligned intentions of the principal actors of the January 15, 1966 military coup d’etat, especially the role of Nzeogwu. In order to achieve this objective, the research made use of both primary and secondary sources of data. These were subjected to initial qualitative analysis. The research concludes that part of the reasons for the misinterpretation of Nzeogwu’s role is the need to justify the failure of the government of the First Republic to satisfy the basic human and material needs of Nigeria. In addition, it establishes the fact that subsequent political equations and configurations in Nigeria have evidently been to the benefit of those who have been at pains to justify the brutality that attended the January 1966 coup d’etat.
A Relational Sociological Analysis of Instagram in Turkey
Authors: Bal Nazar , Kasapoglu Aytul
Published: July 2020

The research problem with the study that underpins this article is that Instagram manipulates the consumption habits of daily life in an intense manner. In this context, the main purpose of the article is to examine how people change their consumption habits by being affected by Instagram in daily life. In this context, answers to the questions of what Instagram and consumption mean in daily life and what are their effects were sought. Along with the globalization process and capitalism, Instagram, which is one of the popular social media tools especially in recent years, has started to affect people positively and negatively in cultural, social and economic terms. One of these effects is consumption habits. However, people's lifestyles and social identities are changing. The theoretical basis of this study is relational sociology and Pierre Bourdieu's (1984) concepts of “habitus”, “field” and “taste”. How Instagram manipulates consumption habits has been tried to be put forward with a Grounded Theory approach. In the empirical part of the study, in-depth interviews were made with 14 women who are Instagram users. Research findings reveal that the consumption habits of individuals change from utilitarian consumption to hedonist consumption. These hedonist consumption habits, on the other hand, can be said to lead people away from their own social realities and to alienate themselves and society.
Perceptions of Russian-Speaking Immigrants: A Case Study in Australia
Authors: Cohan Shovkovyy Oleg
Published: July 2020

This research was conducted in response to one of the most pressing and challenging questions on the agenda of many government offices around the world - “What can be done to better integrate and assimilate immigrants into host communities?” The qualitative study employed ethnographic methods of gathering data, where 170 Russian-speaking immigrants were observed by the insider in their natural settings, for eight months, and at different locations in Brisbane region of Australia; informal, unstructured interviews were conducted with 27 individuals. During observations, it was noticed that many immigrants had experienced one or another sort of difficulties that prevent them from smooth integration into the host society. The further analysis of data derived from immigrants narratives revealed emerging themes, which allowed identifying five factors that, perceived by immigrants as obstacles to integration: (1) employment, (2) education, (3) healthcare, (4) government assistance, and (5) discrimination. Following the logic of inductive reasoning and assumptions of grounded theory, that is seen as a research method in which the theory is developed from the data, the researcher uses research findings to build behavioral Model of Assimilation/ Integration of immigrants. Developed model not only accurately explains why immigrants resist integration but also offers the pathway to further quantification for the measurement of assimilation.

The necessity for human solidarity in Arthur Miller’s All My Sons
Authors: Mowaad Mostafa Saber Abdel-Hamid
Published: July 2020

Arthur Miller’s All My Sons depicts the human tendency of self-deception, betrayal and guilt which leads to the deterioration and the collapse of human values. The intensity of these elements may vary but they run through all of his plays. In All My Sons, Joe, a selfish businessman, in order to save his business from ruin, supplies defective cylinder heads to the American Air Force which results in the death of 21 fighter plane pilots. Joe atones for his crime by committing suicide. According to Miller, the American Dream creates false hopes that prevent people from being proud of what they have accomplished to make their lives better than they would be elsewhere, and eventually fail at achieving anything. Guilt is fundamentally a prosocial behavior because it strengthens interpersonal relationships. It is a kind of regretful, remorseful, painful, and aversive feeling aroused by one’s own actions or inactions. Guilt is different from regret in that guilt is more related to interpersonal harm whereas regret is more related to intrapersonal harm. Guilt is usually related to and is operationalized as the acceptance of responsibility for harm. Guilt has long been related to prosocial behavior. People tend to use altruistic means when under the stress of guilt.1
Freshwater Resource Exploitation: New Security Challenge for Africa

Population growth and human activities such as freshwater resource exploitations continue to have shattering effects on ecological dynamics. These effects are likely not unrelated to issues emanating from climate change and global warming. There is adequate scientific evidence that supports shifting trends in the ecosystem and specifically relating to increased water use and loss of wetlands; that poses a new security challenge for Africa especially, and which without proper intervention, could be catastrophic; resulting in food shortage and profound implications on biodiversity conservation. Many measures have been put in place intended to arrest excessive water extraction; the measures include co-management, encouragement of local community adaptation methods, and good governance. It is unclear whether these methods can catch up with the speed of depletion of the water resources. There is fear that future scarcity in water resources could compound with other issues plaguing Africa to result in conflicts.
Changes in the Described Elements of Sensoji Temple following its Park Designation
Authors: Ito Hiromu
Published: July 2020

How the elements of a religious facility became recognized after its designation as a park was clarified in this study based on the changes in the descriptions of the facility in guidebooks and pictorial charts. Immediately after the facility was designated as a park, the image of a park was merely added to the idea of the temple. However, Kinryusan Sensoji Temple clearly became considered one of the park components only after the full-scale maintenance and division of the park in 1884. These changes were greatly influenced by the changes in the physical environment based on the institutional meaning of the park in addition to the background of the existence and use of the park becoming widely established from the period when it was designated as a park to the period when it was developed into a tourist attraction. While the extent of recognition of Sensoji Temple as a park increased, the extent of recognition of the site as a temple diminished and became limited. Tourists perceived that Sensoji Temple was composed only of Kannondo Hall and spatially considered the entire park as a collection of sections. As a result, the area recognized as a temple was limited to the central part of the Sensoji Temple precinct, while the spatial functions that Sensoji Temple originally possessed were divided and removed. Thus, the characteristics of the temple as a tourist site also changed.
Deteminants of Tax Burden in Vietnam
Authors: Cung Nguyen Huu
Published: July 2020

Taxation is an important tool for each country's government to regulate the economy, distribute income fairly and contribute largely to the state budget. Tax revenue is related to the tax burden. How to achieve tax revenue to ensure an appropriate tax burden rate for the economy and the people is a relatively difficult task for each country. The empirical method is employed on a secondary time series data set during the period 1999-2016 to determine the impact of GDP at current prices, tax revenue, index of economic freedom on tax burden in Vietnam by using a linear approach. The empirical results find that the relationship between gross domestic product and tax burden is a negative sign at 1% significant level. Tax revenue has a positive effect on tax burden at 1% significant level. Economic freedom index has a positive effect on tax burden at 1% significant level. Based on the findings, the article recommends that Vietnam continues to seek positive solutions to enhance the economic growth rate, reducing tax revenue through the transfer of some socio-economic development tasks to the private sector which may be undertaken, strongly equitizing state-owned enterprises, retaining a number of businesses with economy regulatory function and social security.

Optical Potts machine through networks of three-photon down-conversion oscillators
Authors: Honari-Latifpour Mostafa , Miri Mohammad-Ali
Published: July 2020

In recent years, there has been a growing interest in optical simulation of lattice spin models for applications in unconventional computing. Here, we propose optical implementation of a three-state Potts spin model by using networks of coupled parametric oscillators with phase tristability. We first show that the cubic nonlinear process of spontaneous three-photon down-conversion is accompanied by a tristability in the phase of the subharmonic signal between three states with 2π/3 phase contrast. The phase of such a parametric oscillator behaves like a three-state spin system. Next, we show that a network of dissipatively coupled three-photon down-conversion oscillators emulates the three-state planar Potts model. We discuss potential applications of the proposed system for all-optical optimization of combinatorial problems such as graph 3-COL and MAX 3-CUT.
Rock Art and Trade Networks: From Scandinavia to the Italian Alps
Authors: Melheim Lene , Sand-Eriksen Anette
Published: July 2020

This article uses rock art to explore potential bonds between Scandinavia and Italy, starting in the second half of the third millennium BCE with the enigmatic Mjeltehaugen burial monument in coastal western Norway and its striking rock art images, and ending in the first millennium BCE with ship motifs in inland Val Camonica, Italy. While the carved dagger on the Mjeltehaugen slab is unique in its Nordic setting, such weapon depictions are frequently seen on the Continent, e.g. in South Tyrol, and more often in later Nordic rock art. Strong evidence of trade relations between the Italian Alps and Scandinavia is found c. 1500–1100 BCE when the importation of copper from South Tyrol coincided with two-way transmission of luxury items, and again in a different form, c. 1000–700 BCE when strong similarities in burial traditions between the two areas may be seen as evidence of direct cultural connections or a shared cultural koiné. In order to understand the social fabric of these relations and how they unfolded through time, the authors discuss several different models of interaction. It is hypothesised that rock art practices played a role in establishing and maintaining durable social relations, through what we consider to be a two-way transmission of symbolic concepts and iconography during seasonal meetings related to trade and travel.
