We study dynamic bargaining with asymmetric information and arrival of exogenous events, which represent arrival of traders or information. We characterize the unique limit of stationary equilibria with frequent offers. The possibility of arrivals changes equilibrium dynamics. There is delay in equilibrium, and the seller slowly screens out buyers with higher valuations. The seller payoff equals what he can achieve by simply awaiting an arrival. In applications, when buyer valuations fall, average prices drop and delay increases. Surplus division depends on relative arrival rates of buyers/sellers and expected time to trade is a nonmonotonic function of the arrival rate. (JEL C78, D82)

Between “the one who arrives” (and triggers the new age of migrations), and “what happens” (an expression used in some instances by Derrida to refer to deconstruction), there is an eventuality to think about. This brings out a concept of unconditional hospitality which is defined as “hospitality to reality,” “hospitality to the event.” The ethical and political analyses that criticize this notion are far from tackling within this perspective, an aspect on which Derrida himself has not been always clear enough. Furthermore, the “arrivant” (Derrida) shall be understood in the light of the “arrivage” (Marion). The phenomenality expressed by the phenomenon of migration calls for a description to the extent of unconditional eventuality that seems to saturate such phenomenon.

Range estimation based on the array invariant concept exploits the inherent properties of shallow-water waveguide propagation. Multipath arrivals observed on a vertical line array, indexed on vertical arrival angle and time difference of arrival, form what is known as a beam migration pattern in the shape of an ellipse that is a function of source range and the acoustic invariant beta. Fitting the beam migration pattern to an ellipse yields the source range. A property of this beam migration pattern is that it is independent of source depth. Source depth determines how the multipath arrivals are distributed along that ellipse. We will extend previous work on estimating range and present how to estimate depth. This decouples the two estimates and reduces a 2D search process to two 1D processes. We will explore the CRLB structure of the range and depth estimates and demonstrate the results of processing experiment data from the RADAR 2007 experiment in shallow water off the coast of Portugal.

The runway configuration management (RCM) problem governs what combinations of airport runways are in use at a given time, and to what capacity. Runway configurations (groupings of runways) operate under runway configuration capacity envelopes (RCCEs) which limit arrival and departure capacities. The RCCE identifies unique capacity constraints based on which tarmacs are used for arrivals, departures, or both, and their direction of travel. When switching between RCCEs, some decrement in arrival and departure capacities is incurred by the transition. A previous RCM model (Frankovich et al., 2009) accounted for this cost through a required period of inactivity. In this paper, we instead focus on the introduction and assessment of a model capable of marginally decreasing RCCE capacities during configuration transitions. A transition penalty matrix is introduced, specifying the relative costs (in terms of accepted arrival and departure capacities) for switching between RCCEs. The new model benefits from customizable transition penalties which more closely represent real-world conditions, at a reasonable computational cost.

The Runway Configuration Management problem governs what combinations of airport runways are in use at a given time for an airport or a collection of airports. Runway configurations (groupings of runways), operate under Runway Configuration Capacity Envelopes (RCCEs) which limit arrival and departure capacities. The RCCE identifies unique capacity constraints based on which runways are used for arrivals, departures, and their direction of travel. When switching between RCCEs, due to a change in weather conditions or a change in the demand pattern, a decrement in arrival and departure capacities is incurred during the transition. This paper reports computational experience with two distinct models—a robust optimization model that addresses uncertainty in the arrival demand, and a previously studied model that does not include uncertainty in any of the parameters. Test case scenarios are based on data from the John F. Kennedy international airport in New York.

We examine the time-dependent behavior of a birth–death process, whose birth rates and death rates are decreasing and increasing, respectively, with respect to the current state. Such models can be used to describe Markovian queueing systems with exponential reneging, where potential arrivals balk with a certain probability that depends on the number of customers observed upon arrival. Our results are derived by interpreting the birth–death process as the queue-length process of what we refer to as the “knockout queue.”

With the revamping of the Canada Immigration Act in 1985, the demographic profile of new arrivals to Canada took a marked shift to place a priority on better educated, business-class immigrants. Most of these immigrants are from the Pacific Rim, and they have high expectations for the academic achievement of their children in the Canadian school system. The purpose of this study was to look at age on arrival and first-language proficiency of these children, as these factors interact with instructed ESL support on achievement measures in grade 12. Analysis of the data reveals that although all learners benefit from structured ESL support, it is the younger-arriving ESL learners who have the most to gain, even after many years of little or no support. We note that all ESL learners, regardless of age on arrival, struggle to acquire the cultural and metaphoric competence that is beyond the linguistic threshold required for success, but nevertheless central to successful engagement in a literature-based program of studies.

The effect of crop height on the epidemics of Septoria tritici and Stagonospora nodorum was investigated using visual assessment and PCR-based assays. Based on the results of our study, the primary mechanism of disease escape in tall crops is through a reduction of spore arrival. Real-time PCR is an important tool to quantify spore arrival and can, in combination with visual assessment, identify factors involved in the onset and extent of disease development.

Science fiction is often held up as a particularly philosophical genre. For, beyond actualising mind-experiment-like fantasies, science fiction films also commonly toy with speculative ideas, or else engineer encounters with the strange and unknown. Denis Villeneuve's Arrival (2016) is a contemporary science fiction film that does exactly this, by introducing Lovecraft-esque tentacular aliens whose arrival on Earth heralds in a novel, but ultimately paralysing, inhuman perspective on the nature of time and reality. This article shows how this cerebral film invites viewers to confront a counterintuitive model of time that at once recalls and reposes what Gilles Deleuze called a “third synthesis” of time, and that which J. M. E. McTaggart named the a-temporal “C series” of “unreal” time. We finally suggest that Arrival's a-temporal conception of the future as having already happened can function as a key to understanding the fate of humanity as a whole as we pass from the anthropocene, in which humans have dominated the planet, to the “chthulucene,” in which humans no longer exist on the planet at all.

How do air traffic controllers, or ATCos, distribute visual attention and can it vary between controllers? In this study, using primarily eye-tracking data and a couple of on-site interviews, these questions are explored. Two ATCos, with the most similar landings, had their eye-movements recorded with Tobii pro glasses 2 and further analysed by categorizing every fixation into different areas of interest during four landings. Two more ATCos were interviewed briefly during an observational visit to the control tower. The results showed that the ATCos distributed their attention fairly equally between the outside of the control tower and the inside. When attending to something outside the runway was the focus and when attention was inside the control tower the radar was usually the focus. The ATCos differed in their attention distribution by the presumably more experienced ATCo distributing their attention more outside the control tower than the presumably less experienced ATCo. A large number of fixations were not categorized bringing the method of dividing the ATCos eye-tracking view into areas of interest into question.

Timely disseminating marketing related information of agricultural commodities throughout the country is essential in today’s scenario. AGMARKNET portal is one such initiative to collect, compile and disseminate prices and arrival data of agricultural commodities. The information that this portal provides is critical to all the stakeholders associated with agriculture. AGMARKNET aims to deliver correct and complete information to the farmers in order to strengthen their economic position. Farmers can know before going to the markets the price at which the crop can be sold which brings them in a better bargaining position. Consumers can benefit too as this will bring transparency in arrivals, curbing hoarding.
This study aims to develop a diagnostic for major markets where wheat arrivals are high. This diagnostic tool will help the data entry operators to have various checks on the entire process of data entry. Thereby, improving the data quality by monitoring the data reporting process continuously. Statistical Process Control (SPC) can help the correct reporting of data. Microsoft Excel 2016 was used for diagnostic tool development.
The second objective of the study is to forecast the modal prices of wheat for a particular variety using time series modeling. Data filtering, sorting and cleaning are the essential tasks conducted as part of this process. The time series modeling has been attempted to forecast wheat prices in 2017. Microsoft Excel 2016 and Eviews 9 have been used for time series analysis.

Speech is by far the most natural form of communication between human beings. It is intuitive, expressive and contains information at several cognitive levels. We as humans, are perceptive to several of these cognitive levels of information, as we can gather the information pertaining to the identity of the speaker, the speaker's gender, emotion, location, the language, and so on, in addition to the content of what is being spoken. This makes speech based human machine interaction (HMI), both desirable and challenging for the same set of reasons. For HMI to be natural for humans, it is imperative that a machine understands information present in speech, at least at the level of speaker identity, language, location in space, and the summary of what is being spoken.
Although one can draw parallels between the human-human interaction and HMI, the two differ in their purpose. We, as humans, interact with a machine, mostly in the context of getting a task done more efficiently, than is possible without the machine. Thus, typically in HMI, controlling the machine in a specific manner is the primary goal. In this context, it can be argued that, HMI, with a limited vocabulary containing specific commands, would suffice for a more efficient use of the machine.
In this thesis, we address the problem of ``Who spoke what and where", in the context of a machine understanding the information pertaining to identities of the speakers, their locations in space and the keywords they spoke, thus considering three levels of information - speaker identity (who), location (where) and keywords (what). This can be addressed with the help of multiple sensors like microphones, video camera, proximity sensors, motion detectors, etc., and combining all these modalities. However, we explore the use of only microphones to address this issue. In practical scenarios, often there are times, wherein, multiple people are talking at the same time. Thus, the goal of this thesis is to detect all the speakers, their keywords, and their locations in mixture signals containing speech from simultaneous speakers. Addressing this problem of ``Who spoke what and where" using only microphone signals, forms a part of acoustic scene analysis (ASA) of speech based acoustic events.
We divide the problem of ``who spoke what and where" into two sub-problems: ``Who spoke what?" and ``Who spoke where". Each of these problems is cast in a generic latent variable (LV) framework to capture information in speech at different levels. We associate a LV to represent each of these levels and model the relationship between the levels using conditional dependency.
The sub-problem of ``who spoke what" is addressed using single channel microphone signal, by modeling the mixture signal in terms of LV mass functions of speaker identity, the conditional mass function of the keyword spoken given the speaker identity, and a speaker-specific-keyword model. The LV mass functions are estimated in a Maximum likelihood (ML) framework using the Expectation Maximization (EM) algorithm using Student's-t Mixture Model (tMM) as speaker-specific-keyword models. Motivated by HMI in a home environment, we have created our own database. In mixture signals, containing two speakers uttering the keywords simultaneously, the proposed framework achieves an accuracy of 82 % for detecting both the speakers and their respective keywords.
The other sub-problem of ``who spoke where?" is addressed in two stages. In the first stage, the enclosure is discretized into sectors. The speakers and the sectors in which they are located are detected in an approach similar to the one employed for ``who spoke what" using signals collected from a Uniform Circular Array (UCA). However, in place of speaker-specific-keyword models, we use tMM based speaker models trained on clean speech, along with a simple Delay and Sum Beamformer (DSB). In the second stage, the speakers are localized within the active sectors using a novel region constrained localization technique based on time difference of arrival (TDOA). Since the problem being addressed is a multi-label classification task, we use the average Hamming score (accuracy) as the performance metric. Although the proposed approach yields an accuracy of 100 % in an anechoic setting for detecting both the speakers and their corresponding sectors in two-speaker mixture signals, the performance degrades to an accuracy of 67 % in a reverberant setting, with a $60$ dB reverberation time (RT60) of 300 ms. To improve the performance under reverberation, prior knowledge of the location of multiple sources is derived using a novel technique derived from geometrical insights into TDOA estimation. With this prior knowledge, the accuracy of the proposed approach improves to 91 %. It is worthwhile to note that, the accuracies are computed for mixture signals containing more than 90 % overlap of competing speakers.
The proposed LV framework offers a convenient methodology to represent information at broad levels. In this thesis, we have shown its use with three different levels. This can be extended to several such levels to be applicable for a generic analysis of the acoustic scene consisting of broad levels of events. It will turn out that not all levels are dependent on each other and hence the LV dependencies can be minimized by independence assumption, which will lead to solving several smaller sub-problems, as we have shown above. The LV framework is also attractive to incorporate prior knowledge about the acoustic setting, which is combined with the evidence from the data to derive the information about the presence of an acoustic event. The performance of the framework, is dependent on the choice of stochastic models, which model the likelihood function of the data given the presence of acoustic events. However, it provides an access to compare and contrast the use of different stochastic models for representing the likelihood function.

The major essays of the distinguished and prolific Australian-born film critic Adrian Martin have long been difficult to access, so this anthology, which collects highlights of his work in one volume, will be welcomed throughout film studies. Martin offers indepth analysis of many genres of films while providing a broad understanding of the history of cinema and the history of film criticism and culture. These vibrant, highly personal essays, written between 1982 and 2016, balance breadth across cinema theory with almost encyclopedic detail, ranging between aesthetics, cinephilia, film genre, criticism, philosophy, and cultural politics. Mysteries of Cinema circumscribes a special cultural period that began with the dream of critique as a form of poetic writing, and today arrives at collaborative experiments in audiovisual essays. Throughout these essays, Martin pursues a particular vision of what cinema has been, what it is, and what it still could be.

AbstractIn the past decades, South Tyrol, an Italian autonomous province with a German- and Ladin-speaking population and a power-sharing system to protect their cultural features, has witnessed the arrival of many migrants from foreign countries. In addition, as result of the increase in the refugee flows in recent years, thousands of asylum-seekers have passed through and settled in the province. Situated within the ‘local turn’ in migration studies and in the interplay between the fields of migration and security studies, this chapter analyses processes of (de)securitisation vis-à-vis migration in South Tyrol. Adopting the Copenhagen School’s understanding of securitisation as a speech act in combination with a sociological variant that highlights the role of practices, the chapter reveals how, to what extent and in what terms (de)securitisation dynamics have unfolded in South Tyrol regarding the settlement of migrant communities and recent refugee flows. I use a qualitative methodology that looks at discourses and practices as they have emerged in party programmes, political speeches, policy and legal documents. In this way, the chapter will offer a genealogy of (de)securitising discourses and practices at the substate level, revealing the anxieties and problems of dealing with migration when the arrival of migrants meets the presence of old minorities.

AbstractThe coexistence of different cultures in the same legal system is a given fact of contemporary ‘Western’ societies, produced by structural migratory phenomena that are not realistically reversible and that brought about the advent of the so-called ‘multicultural state’. In a multicultural state, a cultural majority lives side-by-side with one or more cultural, ethnic or religious minorities, who sometimes identify themselves with a set of values and principles that could be regarded as incompatible with those of the host country’s legal system, thus generating what has been described by scholars as a ‘meeting’ (or a ‘clash’) of cultures. This chapter documents the shift in Italian legal rulings on specific issues of migrant cultural practices in Italy towards a more assimilationist stance, reflecting the wider political dynamics of migrant and refugee arrivals in Italy.

AbstractIrregular migrants lack the formal authorisation to reside in the country in which they live; therefore, they are at risk of being detained and deported. This chapter will examine the ways in which states respond to irregular migration. It will first consider the various forms of detention and removal of irregular migrants. Return policies for irregular migrants include forced deportation and (semi) voluntary return. The chapter will also discuss push-backs as forms of ‘pre-arrival deportation’, the time that irregular migrants spend in immigrant detention, and what happens after they have been deported. It will then explore the alternative solution, namely regularisation policies, discussing regularisation programmes, like mass amnesties, and regularisation mechanisms through which irregular migrants can regularise themselves on an individual basis.

AbstractFriendships can be interpreted as voluntary relationships between individuals and characterised as relatively amorphous bond. Since migration usually diversifies people’s social bonds, it can be suggested that in this context friendships have to be reconfigured. Even though friendships are important for societal integration and related to individual well-being, migration research has treated friendships as a side issue. This chapter aims to narrow this gap by answering three questions: Are there significant differences between emigrants and non-mobiles in their number of close friends? What are important factors influencing emigrants’ number of close friends abroad? How does this number develop during the first years after emigration? Based on data from the German Emigration and Remigration Panel Study and the German Socio-Economic Panel, the results show that emigrants have more friends than non-mobiles. Additionally, we find that individual characteristics and cultural distance between emigrant and host society or the intension to stay in the emigration country are significantly related to emigrants’ friendship network size. Furthermore, we find that identification with the emigration country is the most influential factor on the size of the friendship networks during the first 2 years after arrival. Our results also provide some evidence that there is an optimal size of the close-friendship-network.

When transporting multiple products in a pipeline, it is important to always understand the location of the head and tail of each batch. The operator will know where batch interfaces are in real-time and be ready to swing the valve at the exact time a batch arrives at a station to deliver product to the right storage tank or an end-customer with minimal contamination. It is relatively easy to track multiple batches in a pipeline with no elevation changes, and a fixed internal diameter. However, it is far more complex to track multiple batches in a pipeline with drastic elevation changes and different sizes in diameter. Column separation of the liquid, also known as slack, occurs when the pipeline pressure drops below the vapor pressure calculated at the liquid temperature in a specific area of the pipeline. This effect reduces the amount of liquid volume contained within the pipeline region, changing the actual physical position of the batch head and tail interfaces, and reducing the accuracy of the volume within the region and the corresponding Estimated Times of Arrival at stations. Draining or filling a pipeline section by delivering product at a different rate from what injected causes the same effect. A scientific approach to calculate the areas of slack and volume contained within a pipeline should provide sufficient information to track batches with a high degree of accuracy. However, it is neither simple nor straightforward to simulate this phenomenon offline, and it is much more challenging in an online, real-time environment. Online, additional complexities affect how batches and their interfaces are tracked, causing a big discrepancy between Estimated and Actual Time of Arrivals. This paper discusses an empirical approach developed to calculate the volume contained within a pipeline region by tracking the volume entering and leaving the region. Estimated and Actual Times of Arrival are within a 15-minute time window after a batch has traveled a total distance of 1,200km with drastic elevation changes along the route. This method has proven that batch tracking can be highly accurate and reliable with less of the theoretical assumptions used in a hydraulic simulation package, with no need to model every single characteristic of the pipeline in detail. This removed the uncertainties that attend those assumptions and allowed this system to perform well on a pipeline with severe slack flow and draining/filling operations.

Aim/Purpose: How does heterogeneous valuation of service affect optimal control of queues? Background We analyze this heterogeneity by adding a component of travel costs, which differ with distance from the service point. Methodology: Mathematical analysis of queuing theory. Analyzing the anarchy function. Contribution: Enabling consumers to make optimal choices based on knowledge about their status, and enabling better control of the organizer. Findings: In the arrival rate is bounded, there is no need of interference. If it is unbounded then in many cases the organizer should impose the socially optimal queue length. Recommendations for Practitioners: In the arrival rate is bounded, there is no need of interference. If it is unbounded then in many cases the organizer should impose the socially optimal queue length. Recommendations for Researchers: Explore the following points: What happens when there are more than one server, located at different point. How should consumers behave, and what is the best way to locate service points. Impact on Society: Handling queues taking into account social welfare. Future Research: What happens when there are more than one server, located at different point. How should consumers behave, and what is the best way to locate service points.

Abstract Microseismic and cross-well strain are both high-end diagnostic tools that provide insight into hydraulic fracture geometry and stimulation effectiveness. However, both datasets have limitations: for example, microseismic can over or underestimate the true fracture geometry, while cross-well strain is restricted to describing a portion of the fracture geometry it is situated to measure. Furthermore, both datasets can show not only the creation of new hydraulic fractures but also the reactivation of previously created hydraulic fractures. The focus of this study is two projects in which both cross-well strain and microseismic were integrated to characterize the geometry of new hydraulic fractures and understand the interaction with pre-existing fractures during well stimulation. The first project is a multi-well development in the Meramec formation of the Anadarko Basin. The second project is the Hydraulic Fracturing Test Site 2 (HFTS2) in the Wolfcamp formation of the Delaware Basin. Both projects collected low-frequency DAS using permanent fibers in offset wells and were monitored with borehole microseismic arrays during stimulations. Organizing the data relative to distance from the active stage and time since stage start, i.e., spatiotemporally, was a key step in understanding what the diagnostics measured during stimulation. Both projects tell a similar story, where wells have extensive interactions with previously created fractures originating from both parent wells and recently completed child wells. This interaction manifests as a quicker arrival and muted strain response in cross-well strain and a more rapid and linear move-out of the triggering front over time in the microseismic. We interpret these signatures to be showing re-dilation of pre-existing fractures. Also visible in the diagnostics are arrivals with slower growth, generating microseismicity with a parabolic move-out of the triggering front over time, and typical strain response with heart-shaped tensional front leading the arrival. This signature is interpreted to be new hydraulic fracture creation and growth. Once this reactivation mechanism is understood for a basin, it can also be noted and described using lower-cost techniques, such as sealed-wellbore pressure monitoring (SWPM). The main motivation for most microseismic and cross-well strain studies is understanding hydraulic fracture geometry; however, interactions with failed media and analysis of either datatype in isolation can cause misinterpretations far from reality. Understanding the range of possible mechanisms measured by these advanced diagnostics is key not just in accurately characterizing fracture geometry but also in understanding the impact of failed media on hydraulic fracture growth. Once understood, these observations can also be used as a baseline to measure success or failure of mitigation trials.

With the implementation of the European ATM Master Plan (SESAR, 2012) job requirements for air-traffic controllers (ATCOs) will alter significantly. Especially the introduction of time-based operations is considered to impose large changes in task operations. A controller-in-the-loop simulation study was designed to assess experts’ judgments on the main human abilities required for working in time-based arrival scenarios with different levels of assistance by an arrival-management system. Five male controllers (mean age: 32.5 years; mean job experience: 10.8 years) licensed for the simulated sector performed on one baseline scenario and four future scenarios. Gaze-data were tracked and questionnaires on situation awareness and workload, as well as a modified Fleishman Job Analysis Survey (F-JAS) were applied. The experts judged the ability to identify problems produced by automation, as well as the ability to stay vigilant as being increasingly required in a highly automated time-based environment. The high number of gaze transitions between aircraft-targets adds objective indication: Under the simulated future conditions ATCOs were hardly able to build up attention guiding expectations which are necessary to keep up with the system- and traffic-parameters. This was also reflected in low situation awareness and high workload ratings.

Purpose – The existence of accommodation capacity is an indispensable condition for carrying out tourist activities. Therefore, the purpose of this research is to find out the influence of accommodation capacity on the number of tourists, the number of overnight stays and the average stay, so as to highlight the importance of this indicator for the tourist potential of Calarasi County. Methodology – In order to analyze the influence of the existing accommodation capacity on the number of tourists, the number of overnight stays and the average stay, the simple regression model was used, so as to find out what percentage of the dependent variables is explained by the dependent variable. The Eviews program was used to create the simple regression model. Findings – Following the application of regression, we found out that in Calarasi County, 30% of the variation in the number of tourists is explained by the variation in existing accommodation capacity. There is also a weak link between existing accommodation capacity and the number of nights spent. Contribution – The present study focused on the influence of accommodation capacity on some indicators of tourist traffic, and the results could meet the decisions that local authorities could take regarding the support of accommodation units in the county.

Facebook news feed personalization algorithm has a significant impact, on a daily basis, on the lifestyle, mood and opinion of millions of Internet users. Nonetheless, such algorithms lack transparency challenging researchers to improve their fairness and accountability. In this paper, we propose a model to capture the dynamics of contents over a timeline (also known as news feed). The input to our model is a fundamental quantity associated to timelines, which we show that can be easily parameterized using real world data: the arrival rate of posts of a given publisher followed by the user. Using real world Facebook traces from the latest elections in Italy, we validate the accuracy of the proposed model and use the model for conterfactual what-if analysis.

The Covid-19 virus pandemic has so far affected all aspects of human life and activity around the planet in an extremely invasive way. What has significantly attracted the attention of the general public is the impact of Covid-19 on the tourism sector, which, last year, suffered daily immeasurable losses. During the crisis caused by the Covid-19 pandemic, areas with relatively low population density came to the forefront in the domain of creating a tourism offer. In times of crisis, rural areas with open, unpolluted spaces, such as protected natural areas, become very attractive and sought after. Bearing in mind that, rural areas are those parts of the territory that has a relatively low population density, but may also have certain characteristics in terms of natural, geographical, and climate specifics, also in terms of the economy, etc. The research part of this paper will deal with the ratio of tourist arrivals and overnight stays, and indexes of tourist demand in 2020 in comparison to 2019, as well as the analysis of the frequency of visitation of tourist spots in Serbia.

The management of end-of-life electronic waste (e-waste) attracts significant attention due to environmental concerns, legislative requirements, consumer interests in green products and market image of manufacturers. However, managing e-waste is complicated by some factors including the high degree of uncertainty of quantity, timing of arrival and quality of the returned products. The variability in the stream of returned end of life (EOL) products makes it difficult to plan for facility materials, equipment and human resource requirements. The aim of this research is to tackle the uncertainty associated with the quantity of received used products. A stochastic programming model for waste stream acquisition systems (compare to market driven systems) is introduced. The model considers the quantity of returned product as an uncertain parameter and determines to what extend the product should be disassembled and what is the best end of life option for each subassembly. The stochastic model is defined in a form of chance constrained programming and is then converted to a mixed integer linear programming. An example is provided to show the application of the model for an uncertain stream of CPUs received in a refurbishing company. Remanufacturers must then decide which proportion of disassembled modules should be processed given specific remanufacturing options.

To increase our understanding of induced seismicity, we develop and implement methods to enhance seismic monitoring capabilities in northeastern British Columbia (NE BC). We deploy two different machine learning models to identify earthquake phases using waveform data from regional seismic stations and utilize an earthquake database management system to streamline the construction and maintenance of an up-to-date earthquake catalogue. The completion of this study allows for a comprehensive catalogue in NE BC from 2014 to 2020 by building upon our previous 2014-2016 and 2017-2018 catalogues. The bounds of the area where earthquakes were located were between 55.5°N-60.0°N and 119.8°W-123.5°W. The earthquakes in the catalogue were initially detected by machine learning models, then reviewed by an analyst to confirm correct identification, and finally located using the Non-Linear Location (NonLinLoc) algorithm. Two distinct sub-areas within the bounds consider different periods to supplement what was not covered in previously published reports - the Northern Montney Trend (NMT) is covered from 2017 to 2020 while the Kiskatinaw Seismic Monitoring and Mitigation Area (KSMMA) is covered from 2019 to 2020. The two sub-areas are distinguished by the BC Oil & Gas Commission (BCOGC) due to differences in their geographic location and geology. The catalogue was produced by picking arrival phases on continuous seismic waveforms from 51 stations operated by various organizations in the region. A total of 17,908 events passed our quality control criteria and are included in the final catalogue. Comparably, the routine Canadian National Seismograph Network (CNSN) catalogue reports 207 seismic events - all events in the CNSN catalogue are present in our catalogue. Our catalogue benefits from the use of enhanced station coverage and improved methodology. The total number of events in our catalogue in 2017, 2018, 2019, and 2020 were 62, 47, 9579 and 8220, respectively. The first two years correspond to seismicity in the NMT where poor station coverage makes it difficult to detect small magnitude events. The magnitude of completeness within the KSMMA (ML = ~0.7) is significantly smaller than that obtained for the NMT (ML = ~1.4). The new catalogue is released with separate files for origins, arrivals, and magnitudes which can be joined using the unique ID assigned to each event.

The rapid arrival of hundreds of thousands of migrants into the European Union (EU) from the Middle East, South Asia, and Africa beginning in 2015 coincided with an increase in support for anti-immigrant rhetoric and the far-right in many European countries. A substantial number of these migrants came to the EU through what became known as the “Balkan Route” a major transit land route cutting through the Western Balkans. In 2016, however, the Route officially “closed,” leaving many of those people attempting to reach Europe effectively stranded within the Balkans. In 2020, for example, approximately 7,000 migrants and refugees were present within the borders of Serbia at any given time. This presence of migrants within the Balkans did not go unnoticed and, in some cases, even spurred increased activity within and mobilization among far-right actors opposed to their presence in the region. Exploring this phenomenon, this report focuses on dynamics surrounding migration and responses to it from the far-right in Serbia, one of the countries on the Balkan Route.
