description: Chromospheric umbral oscillations produce periodic brightenings in the core of some spectral lines, known as umbral flashes. They are also accompanied by fluctuations in velocity, temperature, and, according to several recent works, magnetic field. In this study, we aim to ascertain the accuracy of the magnetic field determined from inversions of the Ca II 8542 Å line. We have developed numerical simulations of wave propagation in a sunspot umbra. Synthetic Stokes profiles emerging from the simulated atmosphere were computed and then inverted using the NICOLE code. The atmospheres inferred from the inversions have been compared with the original parameters from the simulations. Our results show that the inferred chromospheric fluctuations in velocity and temperature match the known oscillations from the numerical simulation. In contrast, the vertical magnetic field obtained from the inversions exhibits an oscillatory pattern with a $\sim$300 G peak-to-peak amplitude which is absent in the simulation. We have assessed the error in the inferred parameters by performing numerous inversions with slightly different configurations of the same Stokes profiles. We find that when the atmosphere is approximately at rest, the inversion tends to favor solutions that underestimate the vertical magnetic field strength. On the contrary, during umbral flashes, the values inferred from most of the inversions are concentrated at stronger fields than those from the simulation. Our analysis provides a quantification of the errors associated with the inversions of the Ca II 8542 Å line and suggests caution with the interpretation of the inferred magnetic field fluctuations.

description: We investigate localization phenomena and stability properties of quasiperiodic oscillations in $N$ degree of freedom Hamiltonian systems and $N$ coupled symplectic maps. In particular, we study an example of a parametrically driven Hamiltonian lattice with only quartic coupling terms and a system of $N$ coupled standard maps. We explore their dynamics using the Generalized Alignment Index (GALI), which constitutes a recently developed numerical method for detecting chaotic orbits in many dimensions, estimating the dimensionality of quasiperiodic tori and predicting slow diffusion in a way that is faster and more reliable than many other approaches known to date.

title: A Comparison of the Ecology of Resident and Translocated Beavers Used for Passive Restoration in Degraded Desert Rivers
Creators: name: Doden, Emma
Publisher: name: Utah State University
Year: 2021

description: Ecosystem engineers are species that create, destroy, modify, or maintain habitat. As ecosystem engineers, beavers have the potential to assist in stream restoration. Translocation is the capture and relocation of an animal to another area. Translocation of nuisance beavers has become a popular method to reduce human-wildlife conflict and restore waterways. However, few projects monitor beavers after release and compare behavior to naturally occurring resident beavers. Translocations to desert rivers are also rare. We captured, tagged, and monitored 47 beavers which we translocated to desert river restoration sites on the Price and San Rafael Rivers, Utah, USA. We compared translocated beaver behavior and activity to 24 resident beavers we also captured and tagged for monitoring. We found high survival rates for resident adult beavers and lower survival rates for resident subadult, translocated adult, and translocated subadult beavers. There were many more river reaches with dams after beaver translocations than before translocations, although we were unable to determine which beavers were responsible for dam building. In general, resident subadult and translocated adult and subadult beavers used ten times longer stretches of river than resident adult beavers. Translocated and resident subadult beavers moved farther from release sites and faster than resident adult beavers in the first six months after release. In contrast, all beavers had similar short-term activity levels, indicating day-to-day activities such as searching for food and resting may not be changed by translocation. Our findings suggest translocated beavers exhibited survival rates, dam building behavior, and movement patterns most similar to resident subadult beavers during dispersal, which is the movement away from the location where a beaver was born. Many translocated beavers left the study sites in search of a suitable area in which to settle, but even those beavers that left the restoration areas may still be benefiting other degraded stretches of river. Further, translocations led to additional beaver dams in the restoration sites, the common goal of beaver-assisted restoration. Low probability of staying near release sites, a high death rate, and wide-ranging movement patterns should be anticipated when translocating beavers. Multiple beaver releases at targeted restoration sites may eventually result in some settlement and dam-building. Resident beavers did not appear to be negatively affected by translocated beavers introduced into the rivers, indicating that translocations can be used to increase low beaver populations to potentially help reach restoration goals more quickly. Improving methods of restoring healthy ecosystems, such as beaver-assisted restoration, is important to maintaining diverse, abundant life globally.
Edward Bond’s theatre for social change : its development in relation to a Brechtian standard
Creators: name: Tully, Betty Marie
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is primarily concerned with Edward Bond's attempt to use the theatre to change society. Bertolt Brecht attempted to use the theatre in the same way and, indeed, to many observers, Bond's work appears to resemble that of Brecht. Therefore as a critical device to understand Bond better, Brecht, with the qualifications outlined in the introduction, is set up as a kind of standard against which Bond's development can be measured. In attempting to use the theatre to change society, Brecht and Bond are obliged to write plays which achieve at least three basic theatrical goals. First, the plays must engage the spectator. To do this, Brecht and Bond rely on techniques familiar to all playwrights. Thus the plays have characters with whom the spectator can feel empathy, a growing sense of aesthetic wholeness, and a wide range of sensuous stimulation. In engaging the spectator, however, Brecht and Bond are always aware that engagement itself is not an end. It is a means of getting the spectator's attention in order to guide him towards something more. All of this material constitutes chapter one. Chapter two concentrates on the second theatrical goal. The plays must expose the fundamental problem of society in such a way as to convince the spectator that social change is necessary and possible. Brecht and Bond agree on the fundamental problem of society: it is the class structure. Their plays are intended as a accurate characterization of society, stressing both its evilness and it's changeability. The third chapter, and the most important in an appreciation of Brecht and Bond, deals with the third goal. The plays must provide behavioural models the spectator can use in working for social change. Brecht and Bond work with "attitude models" and "action models". The proper functioning of the attitude model results in the ideal response both playwrights want: Brecht calls his a critical attitude, Bond, a rational understanding. This response begins to develop in the theatre and is expected to carry over into the life situation when the performance is over. Action models are intended to influence the spectator's life behaviour more directly, providing him with actual models he can imitate or reject. Both Brecht and Bond try to encourage the transfer of these models from the theatre to the life situation by considerably modifying the conventional resolution. In the conclusion the influence of Brecht and Bond on the development of dramatic literature and the theatre is discussed. Finally, some effort is made to evaluate the success of their attempt to use the theatre to change society.

description: This study is concerned wit hthe Patani Fatāwā: A Case Study of the Kitāb al-Fatāwā al-Fatāniyyah of Shaykh Ahmad bin Muhammad Zain bin Mustafa al-Fatāni. The Introduction of the thesis provides a large discussion on the Fatāwā in Islam. The meaning of fatāwā and its development as well as the variation of the fatāwā in the four Islamic schools of thought are widely dealt with. The modern movement on this matter is also discussed. In this work, the Patani historical background beginning from the founding of the Malay Kingdom of Patani in the 14th century to its final incorporation into the Kingdom of Thailand is clearly mentioned. The fall of Patani and the signing of the Anglo-Siamese treaty of 1909 is included. The arrival of Islam into Patani is also described. The traditional Islamic institutions of two main streams are discussed. The Patani 'Ulamā' and their works as well as their biographies are considered. In this study, the Patani Pondok or religious school in Patani has been divided into three periods. Islamic education under Patani 'Ulamā' its writers is one focus. Patani's emergence as a centre of Islamic education in the Malay peninsula shows the Muslim world how important this region is in providing Islamic education to the people of Malay-speaking groups in particular and for interested people in general. The critical declination of the traditional Islamic education in Patani and the nearby area is treated. A deep discussion is also paid to the author of Kitāb al-Fatāwā al-Fatāniyyah: the extent to which the period of his life, his family, his works, his role and his religio-political activities as well as his followers are important is discussed. The final chapter of this work is devoted to an analysis of the Kitāb al-Fatāwā al-Fatāniyyah in several issues including his opinions on legal matters. It is important to mention that the Kitāb al-Fatāwā al-Fatāniyyah is the only well-known book on the classical fatāwā mainly in the Malay language to serve the Malay-speaking groups. Another interesting feature of this book is that its contents cover the problems involved not only of the Muslims in Patani but also those of its neighbouring countries like Malaysia and Cambodia.

description: We present a study of the chemistry of a dense photon-dominated region (PDR) using a time-dependent chemical model. Our major interest is to study the spatial distribution of complex molecules such as hydrocarbons and cyanopolyynes in the cool dense material bordering regions where star formation has taken place. Our standard model uses a homogeneous cloud of density 2x10e4 cm-3 and temperature T=40 K, which is irradiated by a far-ultraviolet radiation field of intermediate intensity, given by X=100. We find that over a range of times unsaturated hydrocarbons (e.g., C2H, C4H, C3H2) have relatively high fractional abundances in the more external layers of the PDR, whereas their abundances in the innermost layers are several orders of magnitudes lower. On the other hand, molecules that are typical of late-time chemistry are usually more abundant in the inner parts of the PDR. We also present results for models with different density, temperature, intensity of the radiation field and initial fractional abundances. Our results are compared with both high- and moderate-angular resolution observations of the Horsehead nebula. Our standard model is partially successful in reproducing the observations. Additional models run with different physical parameters are able to reproduce the abundance of many of the observed molecules, but we do not find a single model that fits all the observations at the same time. We discuss the suitability of a time-dependent model of a dense PDR such as ours as an estimator of the age of a PDR, provided that enough observational data exist.

description: We consider classical and quantum propagators for two different time intervals. If these propagators follow one another in a Fibonacci sequence we get a discrete quasiperiodic system. A theorem due to Nielsen provides a novel conserved quantity for this system. The Nielsen quantity controls the transition between commutative and non-commutative propagation in time. The quasiperiodically kicked oscillator moreover is dominated by quasiperiodic analogues of the Floquet theorem.

Examination of urban sprawl characteristics and of the role of soil quality in peripheral land use changes - Greater Vancouver
Creators: name: Westover, Dennis M.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines some of the problems associated with urban sprawl, and attempts to determine the role of soil quality with respect to land use changes on four rural-urban fringe sites in the metropolitan Vancouver area. Part I describes various characteristics of, and problems created by, urban sprawl, its effects on the countryside, and reasons why it occurs. In Part II, the study sites are described in terms of soils, parent materials, drainage, and topography. In addition, physical and cultural information regarding the regions surrounding each site is given to portray each site in its larger context. Details and evaluation of the research results follow. Four sites, one in each of the municipalities of Delta and Langley and two in the Municipality of Richmond, were selected with features reflecting the physical heterogeneity of the Lower Fraser Valley and for their proximity to urban centres. Four series of air photographs were assembled and examined, in conjunction with soils maps, to determine what land use modification had occurred over a period of about twenty years. Land use changes were correlated with soils data to determine which soils were most affected by urban development. The results of this study appear to indicate that soil quality (for agriculture) by itself is insufficient to delay urbanization of fringe land. Other factors, such as isolation from urban centres, zoning provisions, and economic viability, are as important as soil quality in determining the fate of agricultural land on the rural-urban fringes of Greater Vancouver.
title: Classical Venturi Meter Performance Downstream of the Through Leg of a Tee Junction
Creators: name: Day, Matthew P.
Publisher: name: Utah State University
Year: 2021

description: The purpose of this research was to analyze the accuracy of a Classical Venturi meter installed downstream of the through leg of a tee junction. A flowmeter that functions inaccurately due to improper installation may cause revenue loss for any company or organization involved in extraction, transportation, production, or purchasing of fluid resources and products. This research used physical data coupled with data produced by numerical models to determine how to correct the Classical Venturi meter’s inaccuracies created by this particular installation.
Results show the capability of measuring the flow rate accurately was greatly affected when most of the flow was directed through the branch of the tee junction. As a greater ratio of water is directed through the meter, the accuracy increases. While physical laboratory calibrations remain the most effective way to ensure best metering accuracy, correction factors may be used to account for such installations if laboratory testing is not possible.
$α$-Symmetries, Coloured Dimensions and Gauge-String Correspondence
Creators: name: Polyakov, Dimitri
Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We propose a scenario of gauge-string correspondence by relating the SU(3) colour group to hidden space-time isometries originating from extra dimensions. These isometries ($α$-symmetries) are the special symmetries of RNS superstring theories under global non-linear space-time transformations. The vertex operators for the octet of gluons are constructed by the procedure of ``photon painting'', that is, with the SU(3) subgroup of the $α$-symmetry generators acting on a regular open string photon, so the corresponding open string excitations are in the adjoint of SU(3). Remarkably, the operator algebra of these massless gluon vertices is closed and possesses the full zigzag symmetry, crucial for the isomorphism between open strings and QCD. As a result, the scattering amplitudes of the constructed open string vertex operators have a field-theoretic rather than a stringy structure, including the absense of standard tower of massive intermediate states.Our model also suggests that the total number of underlying hidden dimensions is three, with each extra dimension carrying its appropriate SU(3) colour and anticolour.

title: The theatricality of Edward Bond's plays
Creators: name: Barakat, Mohsen Mosilhi A
Publisher: name: University of Kent
Year: 1990

description: This thesis examines the theatricality of Edward Bond's plays, the devices, methods and aspects of characterisations, and the dramatic strategies and structure that emphasise the political consciousness behind them. It investigates the relationship between Bond's drama and social reality through the mentioned aspects, concentrating on the technicality of the playwriting. Apart from the Introduction and Conclusion, the thesis is divided into three parts. Part One investigates Bond's main anti-illusory devices. Chapter One discusses the topic of the histrionic words and actions. Chapter Two discusses the trial scenes in the plays and concludes that with the exception of Human Cannon, all Bond's courtrooms are diegetic, occurring within the narration. Chapter Three investigates three dramatic devices which are connected in the plays: 1) the atmosphere of playfulness or the sequences of horseplay, 2) the divided focus of aggro-effect which developed into 3) simultaneous action. Chapter Four focuses on the play-within-the-play especially when it is used as a detaching/detached device. Chapter Five investigates Bond's dramatic lyrics and songs. Part Two concentrates on Bond's methods of characterisation. As part of his schematic structure, Bond uses some figures to represent an abstract notion. Chapter One investigates the phenomenon of father figures (or "Wise Fools") which develop into the ultimate father figure/artist. These father figures are always portrayed in relation to young figures who are split into two halves. One of these halves represents the submission to socialised morality and the other represents the search for an alternative political system to the dehumanising one of the father figure. This oppositional configuration of the Siamese twins is the topic of Chapter Two. Chapter Three looks at Bond's employment of ghost figures, some of which die a second lime in the play. The chapter links these life-in-death representatives to other sorts of figures who represent death-in-life. These latter figures are called corpora, metaphorically dead characters. The possessed figures are the subject of Chapter Four which concludes that Bond's uses of mad figures is theatrical and gives little attention to illusion. Part Three is divided superficially into three chapters to deal with Bond's plays and their structure: Chapter One deals with the plays from The Pope's Wedding to The Sea, Chapter Two from Bingo to The Bundle, and Chapter Three from The Worlds to The War Plays. This part uses the findings of the earlier parts to facilitate an overview of the plays in order to specify the principal features of Bond's increasing theatricality, a theatricality which he uses as a vehicle to cany his own political analysis of the situation presented on the stage.

description: The human resource (HR) domain contains various types of privacy-sensitive textual data, such as e-mail correspondence and performance appraisal. Doing research on these documents brings several challenges, one of them anonymisation. In this paper, we evaluate the current Dutch text de-identification methods for the HR domain in four steps. First, by updating one of these methods with the latest named entity recognition (NER) models. The result is that the NER model based on the CoNLL 2002 corpus in combination with the BERTje transformer give the best combination for suppressing persons (recall 0.94) and locations (recall 0.82). For suppressing gender, DEDUCE is performing best (recall 0.53). Second NER evaluation is based on both strict de-identification of entities (a person must be suppressed as a person) and third evaluation on a loose sense of de-identification (no matter what how a person is suppressed, as long it is suppressed). In the fourth and last step a new kind of NER dataset is tested for recognising job titles in texts.

In recent years, we have seen the emergence of new compute-intensive and delay-critical mobile applications, such as virtual/augmented reality, online gaming, ultra-high-definition video streaming and autonomous driving. Multi-access edge computing (MEC) has become a key technology in 5G networks to shift computational tasks from resource-limited mobile devices to nearby servers placed at the edge of the network. The resulting computation offloading mechanism enables peripheral mobile devices to save battery energy and makes simple devices, as in the Internet-of-Things scenario, able to run sophisticated applications.

The energy resolution measured by electrons is Delta{E}/E=2.8%/\sqrt{E} + 1.3%. The position resolution for electrons is Delta{x}=3.1 + 15.4/sqrt{E} mm in the center of the cell. The lateral non-uniformity of the prototype energy response to electrons and MIPs has turned out to be negligible. Obtained experimental results are in a good agreement with Monte-Carlo simulations.

It involves a threshold cusp interfering constructively with either or both (i) a resonance produced via confinement, (ii) attractive t- and u-channel exchanges. More generally, it is suggested that resonances are eigenstates generated by mixing between confined states and long-range meson and baryon exchanges.

Creators: name: Dong, Mengyi
Publisher: name: University of Glasgow
Year: 2025

description: The Chinese society has experienced great changes after the establishment of PRC in 1949, and especially after the economic reform in 1978. Its achievement has been an amazing success and quite unanticipated in many respects. However, inequality problems, such as the income gap between the rich and poor, rural and urban areas, eastern and western regions, are also coming up and becoming significant in the society.

Most sociological analysis of the different ways of justification, in the meanwhile, is rooted in the western values, and needs to be developed into the Chinese context.

Based on newspaper articles collected from seven Chinese newspapers over 12 years, the justification framework was studied in a Chinese context. The analysis of justification of Boltanski and Thévenot (2006) was explored through the dispute of working hours and pay in China. In this study, it was found that justifications in the Chinese society was influenced by its own culture and socialist attributes, and variations are recognised in the Chinese mode of justification compared with the Boltanski and Thévenot original work. A new logic of justification also emerged from the unique Chinese context. In the dispute, it also found that the justifications are changing over the years, and the preference of the logics varies between different actors. Moreover, this study also found a dialectical relationship between the discourse and practice of justification in the Chinese society.

The study contributes to the work of Boltanski and Thévenot (2006) by expanding it to a new context, and by identifying a new logic of justification of significance in the Chinese context.

description: The sodium laser guide star (sLGS) adaptive optics (AO) system has become an essential component for large ground-based optical/infrared telescope. The performance of the AO system can be significantly hindered if the on-sky spot profile of its sLGS is degraded by the turbulence along the laser launching uplink path. One effective method to overcome this problem is to perform real-time pre-correction on the laser before it is launched onto the sky to counter this turbulence effect especially for the lower altitude where turbulence is stronger. The by-product Rayleigh backscatter generated by large molecule and aerosols at low altitude when projecting sLGS is a perfect candidate for real time detection of low altitude turbulence. It is therefore important to evaluate whether this by-product of a sodium laser guide star could achieve suitable performance for wavefront sensing. In this paper, we attempt to answer the question regarding to the achievable photon return of such Rayleigh backscattered plume. A comparison between results from our field test and theoretical model of MSISE-90 was presented. We showed that the greatest differences is less than 20% which hints the applicability of using the defocused Rayleigh plume as wavefront sensing signal for different turbulence strengths. The result also showed that in case of strong (Fried parameter (r0) of 5 cm) or moderate (r0 of 10 cm) turbulence, the optimum center for range gating is 9 km, and the corresponding value of range gate depths are 3 km, 1.1 km, 0.56 km and 0.28 km when subaperture sizes are 3 cm, 5 cm, 7 cm and 10 cm, with the maximum pulse repetition frequency at 1500 Hz.
title: The Effect of Bit Depth on High Temperature Digital Image Correlation Measurements
Creators: name: Jarrett, Steven Robert
Publisher: name: Utah State University
Year: 2021

description: Digital Image Correlation (DIC) is a camera-based method of measuring mechanical displacement and strain which is commonly used in high-temperature experiments due to its ability to take contactless measurements. High-temperature DIC is challenging due to light emitted from the sample which can saturate the camera sensor. Blue-DIC and UV-DIC have been developed to minimize this effect, but the maximum sample temperature range of DIC remains a function of the camera and camera settings. Bit depth, also referred to as color depth or number of bits, is an important camera setting which affects the dynamic range of an image, but which has received insufficient attention in DIC literature. In this work, the effect of bit depth on DIC measurements is investigated both analytically and experimentally. If image noise is sufficiently low, increasing bit depth reduces DIC random error. Using increased bit depth and reduced exposure time, the maximum sample temperature for DIC measurements was shown to increase without negative impact on measurement precision.

description: We demonstrate theoretically that it is possible to manipulate electron or hole spins all optically in semiconducting carbon nanotubes. The scheme that we propose is based on the spin-orbit interaction that was recently measured experimentally; we show that this interaction, together with an external magnetic field, can be used to achieve optical electron-spin state preparation with a fidelity exceeding 99%. Our results also imply that it is possible to implement coherent spin rotation and measurement using laser fields linearly polarized along the nanotube axis, as well as to convert spin qubits into time-bin photonic qubits. We expect that our findings will open up new avenues for exploring spin physics in one-dimensional systems.

description: Viscous fluid exiting a long horizontal circular pipe develops a complex structure comprising a primary jet above and a smaller secondary jet below with a thin fluid curtain connecting them. We present here a combined experimental, theoretical and numerical study of this 'Torricelli's curtain' phenomenon, focusing on the factors that control its morphology. We propose a theoretical model for the curtain in which particle trajectories result from the composition of two motions: a horizontal component corresponding to the evolving axial velocity profile of an axisymmetric viscous jet, and a vertical component due to free fall under gravity. The model predicts well the trajectory of the primary jet, but somewhat less well that of the secondary jet. We suggest that the remaining discrepancy may be explained by surface tension-driven (Taylor-Culick) retraction of the secondary jet. Finally, direct numerical simulation reveals recirculating 'Dean' vortices in vertical sections of the primary jet, placing Torricelli's curtain firmly within the context of flow in curved pipes.

description: We consider a unitary coupled channel model to describe the low energy proton-antiproton scattering and the lower Coulomb-like protonium states. The existence of deeper quasi-bound states of nuclear nature is found to be a consequence of the experimental data. The properties of these states as well as the protonium annihilation densities are described and the difference with respect to the optical models description are manifested.

description: We study charged fluid spheres under the 4-dimensional Einstein-Maxwell space-time. The solutions thus obtained admitting conformal motion. We also investigate whether the solutions set provide electromagnetic mass models such that the physical parameters including the gravitational mass arise from the electromagnetic field alone. In this connection three cases are studied here in detail with the propositions: (1) $p = - ρ$, (2) $σe^{λ/2} = σ_0$ and (3) $8 πp - E^2 = p_0$ where $ρ$, $p$, $σ$ are respectively the usual matter density, fluid pressure and charge density of the spherical distribution. Based on these assumptions several features are explored which seems physically very interesting.

Transformers and Graph Neural Networks for Spell Checking
Creators: name: Walter, Sebastian
Publisher: name: Zenodo
Year: 2022

description: Spell checking is a general term for methods that detect or correct spelling errors in natural language text. Such methods can not only help with correcting human written text, they can also improve the performance and robustness of natural language processing systems dealing with misspelled text, when applied as a preprocessing or postprocessing step. We study the usage of Transformers and graph neural networks for spelling error detection on sequence and word level, as well as spelling error correction. We show that open vocabulary sequence-to-sequence Transformers can perform well for spelling correction. We also experiment with ways to represent text not as sequences of tokens, but rather as word graphs to be processed with graph neural networks. As a simple way to boost spelling error detection performance we propose to enrich misspelled input texts with additional word features. Our models perform better than most of the strong baselines for both artificially generated benchmarks and benchmarks built from real data. They achieve word accuracies of over 98% for word-level spelling error detection and F1 scores of over 80% for spelling error correction, while running fast enough to be used in practice.

description: Automatic sentiment analysis play vital role in decision making. Many organizations spend a lot of budget to understand their customer satisfaction by manually going over their feedback/comments or tweets. Automatic sentiment analysis can give overall picture of the comments received against any event, product, or activity. Usually, the comments/tweets are classified into two main classes that are negative or positive. However, the negative comments are too abstract to understand the basic reason or the context. organizations are interested to identify the exact reason for the negativity. In this research study, we hierarchically goes down into negative comments, and link them with more classes. Tweets are extracted from social media sites such as Twitter and Facebook. If the sentiment analysis classifies any tweet into negative class, then we further try to associates that negative comments with more possible negative classes. Based on expert opinions, the negative comments/tweets are further classified into 8 classes. Different machine learning algorithms are evaluated and their accuracy are reported.

description: We investigate the connection between dark energy and fourth order gravity by analyzing the behavior of scalar perturbations around a Friedmann-Robertson-Walker background. The evolution equations for scalar perturbation are derived using the covariant and gauge invariant approach and applied to two widely studied $f(R)$ gravity models. The structure of the general fourth order perturbation equations and the analysis of scalar perturbations lead to the discovery of a characteristic signature of fourth order gravity in the matter power spectrum, the details of which have not seen before in other works in this area. This could provide a crucial test for fourth order gravity on cosmological scales.

ASEAN’s Environmental Challenges and Non-Traditional Security Cooperation: Towards a Regional Peacekeeping Force?
Creators: name: Borchers, Henning
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2014

description: This article reflects on the prospect for an ASEAN peacekeeping force and regional security cooperation. I argue that progress on ‘soft’ security issues stands to facilitate a slow deepening of ‘hard’ security cooperation at the ASEAN level. Governments of ASEAN member states are still reluctant to develop a regional mechanism for conflict resolution, which they perceive to be a challenge to the norms of non-interference and state sovereignty. Yet, these norms are subject to dynamic shifts in the security environment that regional governments now have to manage. The establishment of mechanisms to address politically less controversial non-traditional security issues such as environmental challenges stands to further develop and consolidate military-to-military ties and deepen political trust among member states. An ASEAN standby force for emergency response and disaster relief has become a politically acceptable initiative and could set the stage for the development of an ASEAN peacekeeping force.

Separatist Conflicts in the ASEAN Region: Comparing Southern Thailand and Mindanao
Creators: name: Rupprecht, Kathrin
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2014

description: This paper examines two cases of separatist conflict, namely the conflict in Southern Thailand and the conflict in the southern Philippines. Both conflicts have been long-lasting, extremely violent, and embedded in ethnic and religious sentiments. The comparison shows that there are structural analogies in both conflict cases that indicate similar root causes. State-internal conflicts of this scale are not purely a matter of national politics. States and non-state actors have influenced – and are still influencing – both separatist conflicts in various ways and towards different outcomes. It becomes apparent that non-traditional security issues that are linked to state-internal conflicts demand a more proactive role of ASEAN in the field of conflict management.
