Resumen

AbstractA multi-hierarchy simulation model aiming magnetic reconnection studies is developed and improved in which macroscopic and microscopic physics are computed consistently and simultaneously. Macroscopic physics is solved by mag-netohydrodynamics (MHD) algorithm, while microscopic dynamics is expressed by particle-in-cell (PIC) algorithm. The multi-hierarchy model relies on the domain decomposition method, and macro- and micro-hierarchies are interlocked smoothly by hand-shake scheme. As examination, plasma flow injection is simulated in the multi-hierarchy model. It is observed that plasmas flow from a macro-hierarchy to a micro-hierarchy across the magnetic field smoothly and continuously.

Resumen

Based on a 4 × 4 matrix spectral problem, a super Degasperis–Procesi (DP) equation is proposed. We show that under a reciprocal transformation, the super DP equation is related to the first negative flow of a super Kaup–Kupershmidt (KK) hierarchy, which turns out to be a particular reduction of a super Boussinesq hierarchy. The bi-Hamiltonian structure of the super Boussinesq hierarchy is established and subsequently produces a Hamiltonian structure, as well as a conjectured symplectic formulation of the super KK hierarchy via suitable reductions. With the help of the reciprocal transformation, the bi-Hamiltonian representation of the super DP equation is constructed from that of the super KK hierarchy. We also calculate a positive flow of the super DP hierarchy and explain its relations with the super KK equation. Infinitely many conservation laws are derived for the super DP equation, as well as its positive flow.

Resumen

This study aims to describe how a tool can be developed by assessing risk and cost within the supply chain of a company. By interviewing stakeholders of the chosen case company, and later analysing their answers with the help of a thematic analysis, we were able to isolate the risk criteria seen as significant. Quality, people, delivery, cost-variation, flexibility and information risk were then used in an AHP model, together with the addition of a cost criterion. By using the AHP methodology, we were able to establish the relation between risk and cost, the different risk criteria and the different product flows considered. The AHP resulted in a matrix which presents the internal relations which can be used as a tool when choosing between different product flows. The purpose of this tool is to help mitigate some of the uncertainties that can emerge when making decisions within the supply chain. The data used in this study is based on the input of the case company, the general application of the matrix have therefore not been tested.
Studien syftar till att beskriva hur ett verktyg kan utvecklas genom att risk och kostnad i ett företags logistikkedja tas i beaktning. Riskerna som behandlas i rapporten identifierades genom att intervjua nyckelpersoner inom det fallföretag som studien utgick ifrån. För att identifiera de risker som ansågs påverka valet av produktflöde, genomfördes en tematisk analys av intervjumaterialet där riskkriteriernas relativa frekvens uppmättes. Den tematiska analysen resulterade i en enkät där parvisa jämförelser mellan riskelement och produktflöden utfördes utefter en beslutshierarki som utarbetats. Resultatet från den tematiska analysen och enkäten visade att risker kopplade till, kvalité, kompetens, leverans, kostnadsvariationer, flexibilitet samt information skall ges en större vikt när produktflöden utvärderas relativt den kostnad som flödena ger upphov till. Resultatet har sammanställts i en matris, där förhoppningen är att matrisen skall hjälpa motverka en del av den osäkerhet som kan uppstå när produktflöden utvärderas. Matrisen i sig är framtagen med hjälp av fallföretaget och dess generella applicering har därför inte testats.

Resumen

Enterprise Resource Planning (ERP) systems have been in existence for over 2 decades yet businesses are still losing billions of dollars annually in the implementation of software designed to reduce costs and increase profitability. The inability to manage risks is an area that contributes to these losses, specifically due to uncertain outcomes when dealing with an interconnected construct such as risk, and a research gap at the tactical and operational levels between risks and controls. A comparative case study approach, encompassing 12 different organisations was adopted to explore emerging patterns at the project implementation level, and from this three contributions emerged. After observing risks behaving in a hierarchical fashion with predictable results, Hierarchy of Risk models representing different implementation stages were constructed. Although these models are still in their formative stages, it may prove useful in furthering our understanding of the close inter-relationship between different risks, where they occur in ERP implementations and the implications of managerial choice when determining risk prioritisation. A second finding is that no direct linear relationship appears to exist between risks and controls. Rather, this counter-intuitive finding suggests that it is additional factors including risk categories, implementation stages, prior control decision making and the hierarchical flow-on effect of impacts as a consequence of identified risks. Finally, by combining the Hierarchy of Risk models and the risk-to-impact-to-control relationship, a method of reverse engineering portfolios of control was discovered. This potentially offers an explanation as to how portfolios of control can be constructed, and why they are essential in ERP implementations.

Resumen

In order to satisfy the global requirement for transport fuel sustainably, renewable liquid biofuels must be developed. Currently, two biofuels dominate the market; bioethanol for spark ignition and biodiesel for compression ignition engines. However, both fuels exhibit technical issues such as low energy density, poor low temperature performance and poor stability. In addition, bioethanol and biodiesel sourced from first generation feedstocks use arable land in competition with food production, and can only meet a fraction of the current demand. To address these issues it is vital that biofuels be developed from truly sustainable sources, such as lignocellulosic waste resources, and possess improved physical properties. To improve and control the physical properties of a fuel for specific application, one must be able to tailor the products formed in its production process. All studies within this thesis, therefore, have the aim of assessing the fuels produced for their variability in physical property, or the aim of directing the process considered to specific fuel molecules. In Chapter 2, spent coffee grounds from a range of geographical locations, bean types and brewing processes were assessed as a potential feedstock for biodiesel production. While the lipid yield was comparable to that of conventional biodiesel sources, the fatty acid profile remained constant irrespective of the coffee source. Despite this lack of variation, the fuel properties varied widely, presumably due to a range of alternative biomolecules present in the lipid. Though coffee biodiesel was produced from a waste product, the fuel properties were found to be akin to palm oil biodiesel, with a high viscosity and pour point. The blend level would therefore be restricted. In Chapter 3 the coffee lipid, as well as a range of microbial oils potentially derived from renewable sources were transformed into a novel aviation and road transport fuel through cross-metathesis with ethene. Hoveyda-Grubbs 2nd generation catalyst was found to be the most suitable, achieving 41% terminal bond selectivity under optimum conditions. Metathesis yielded three fractions: an alkene hydrocarbon fraction suitable for aviation, a shorter chain triglyceride fraction that upon transesterification produced a short chain biodiesel fuel, and a multifunctional volatile alkene fraction that could potentially have application in the polymer industry. Though there was variation for the road transport fuel fraction due to the presence of long chain saturates, the compounds fell within the US standard for biodiesel. The aviation fraction lowered the viscosity, increased the energy density, and remained soluble with Jet A-1 down to the required freezing point. Oleaginous organisms generally only produce a maximum of 40% lipid, leaving a large portion of fermentable biomass. In Chapter 4, a variety of ethyl and butyl esters of organic acids – potentially obtainable from fermentation – were assessed for their suitability as fuels in comparison to bioethanol. One product, butyl butyrate, was deemed suitable as a Jet A-1 replacement while four products, diethyl succinate, dibutyl succinate, dibutyl fumarate and dibutyl malonate, were considered as potential blending agents for diesel. Diethyl succinate, being the most economically viable of the four, was chosen for an on-engine test using a 20 vol% blend of DES (DES 20) on a chassis dynamometer under pseudo-steady state conditions. DES20 was found to cause an increase in fuel demand and NOx emissions, and a decrease in exhaust temperature, wheel force, and CO emissions. While fermentation is generally directed to one product, producing unimolecular fuels, they do not convert the entirety of the biomass available. An alternative chemical transformation is pyrolysis. In Chapter 5, zeolite-catalysed fast pyrolysis of a model compound representative of the ketonic portion of biomass pyrolysis vapour – mesityl oxide – was carried out. The aim of this study was to understand the mechanistic changes that occur, which could lead to improved bio-oil yields and more directed fuel properties of the pyrolysis oil. While HZSM-5 and Cu ZSM-5 showed no activity for hydrogenation and little activity for oligomerisation, Pd ZSM-5 led to near-complete selective hydrogenation of mesityl oxide to methyl isobutyl ketone, though this reduced at higher temperatures. At lower temperature (150-250 °C), a small amount of useful oligomerisation was observed, which could potentially lead to a selective pyrolysis oligomerisation reaction pathway.

Resumen

Sverige idag genererar byggbranschen 12 miljoner ton avfall per år. Enligt svensk lag ska avfallet sorteras för att öka möjligheten till återvinning och återbruk. Byggbranschen står för drygt 20 procent av växthusgasutsläppen i Sverige och genom att återbruka byggmaterial kan denna siffra reduceras. Avsikten med detta examensarbete är att lyfta ett antal möjligheter för att minska klimatavtrycket från byggbranschen. Föreliggande studie syftar därför till att fokusera på de framgångsfaktorer som identifierats hos utmärkande projekt på Skanska gällande återbruk av byggmaterial och produkter. Syftet med studien är att undersöka och belysa de utmaningar som finns med att återbruka samt att uppmärksamma tillvägagångssätt för hur arbete med att återbruka kan ökas.Studien har baserats på intervjuer samt litteratursökning inom ämnet återbruk. Fem deltagare i olika projekt hos Skanska har intervjuats där återbruk varit en del av processen. Arbetet har begränsats till fem intervjudeltagare då det ansågs vara tillräckligt för att besvara studiens syfte. Studien har avgränsats till återbrukat byggmaterial och produkter från byggnader, där material från anläggningsarbeten inte inkluderas. Arbetet skrivs i samarbete med Skanska.De framgångsfaktorer som har identifierats i resultatet är att det är betydelsefullt att lägga god tid på materialinventering och att systematiskt dokumentera de material som finns att tillgå, samt att planering av återbruk sker tidigt i processen. En annan framgångsfaktor för att lyckas med återbruk är att involvera externa aktörer som kan förmedla materialet vidare. De utmaningar som finns med att återbruka byggmaterial och produkter är de krav som ställs genom myndigheter och i lagar. Även kunskapsnivån är bristfällig när det kommer till återbruk i branschen och därmed problematiseras processen. För att anamma återbruk i framtiden kommer det cirkulära byggandet och det långsiktiga perspektivet vara av betydelse inom byggbranschen. Ett sätt för att arbeta med återbruk är att involvera projektörer tidigt i processen genom att förse dem med återbrukat material som går att projektera in i projektet. Vid projekteringen av byggnader bör även materialens framtida återbruk finnas i åtanke. När återbruk blir en del av fler byggprojekt kommer det medföra att avfallet minimeras, det kommer främja företagens hållbarhetsarbete samt att klimatpåverkan från branschen med största sannolikhet kommer minska.
The construction industry generates 12 million tons of waste annually in Sweden alone. The waste according to Swedish law has to be sorted in order to increase the possibility of recycling and reuse. The construction industry produces 20 percent of the Swedish greenhouse gas emissions and by reusing building materials this number can be reduced. The intention of this bachelor's thesis is to illustrate possibilities for reducing the industry's climate footprint. Following thesis intends to focus on identifying the success factors of prominent projects regarding reuse of building materials and products at Skanska. The purpose of the thesis is to explore and illuminate the challenges that come with reusing and detect approaches on how to increase work with reused materials.The thesis is based on interviews and literature in the subject of reuse. Five participants from different projects at Skanska where reuse was a part of the process was interviewed. The interviews were limited to five participants because it was considered to be enough to answer the purpose of the study. The study is limited to reuse of materials and products from buildings, waste from other parts of the industry is not included. This study is written in a collaboration with Skanska.The success factors that were found in this study is that it is important to assign the material listing phase a good amount of time, to systematically document the materials at hand and to plan to reuse early in the process. Another success factor to reusing is to involve external vendors that can help assign the material to new proprietors. The challenges that come with reusing building materials and products are the requirements set by authorities and laws. Also the level of knowledge in the industry about reuse is inadequate which complicates the process. The circular flow and long-time perspective will be of importance in order to appropriate reuse in the building industry in the future. One way to initiate this is by involving architects early in the process by providing them reused materials to plan into their project. In the design of new buildings, the future reuse of the materials should be kept in mind. When reuse becomes a part of more building projects it will result in less waste, the business’ sustainability work will advance and the climate footprint from the industry will most likely get reduced.

Resumen

Le Cloud Computing a bouleversé la façon dont sont développés et déployées les logiciels. De nos jours, les applications Cloud sont conçues comme des systèmes distribués, en constante évolution, hébergés dans des data~center gérés par des tiers, et potentiellement même dispersés dans le monde entier. Ce changement de paradigme a également eu un impact considérable sur la façon dont les logiciels sont monitorés : les applications cloud se sont développées pour atteindre l'ordre de centaines de services, et les outils de monitoring ont rapidement rencontré des problèmes de mise à l'échelle. De plus, ces outils de monitoring doivent désormais également traiter les défaillances et les pannes inhérentes aux systèmes distribués, comme par exemple, les pannes partielles, les configurations incohérentes, les goulots d'étranglement ou même la vampirisation de ressources. Dans cette thèse, nous présentons une approche basée sur une nouvelle source de télémétrie qui s'est développée dans le domaine du monitoring des applications Cloud. En effet, en nous appuyant sur le récent standard OpenTelemetry, nous présentons un système qui convertit les données de "traces distribuées" en un graphe de propriétés hiérarchique. Grâce un tel modèle, il devient possible de mettre en évidence la topologie des applications, y compris la répartition sur les différentes machines des programmes, y compris sur plusieurs data-centers. L'objectif de ce modèle est donc d'exposer le comportement des fournisseurs de service Cloud aux développeurs qui maintiennent et optimisent leur application. Ensuite, nous présentons l'utilisation de ce modèle pour résoudre certains des défis majeurs des systèmes distribués~: la détection des communications inefficaces entre les services et l'anticipation des goulots d'étranglement. Nous abordons ces deux problèmes avec une approche basée sur la théorie des graphes. La composition inefficace des services est détectée avec le calcul de l'indice de hiérarchie de flux. Une plateforme Proof-of-Concept représentant un cluster Kubernetes zonal pourvu d'une instrumentation OpenTelemetry est utilisée pour créer et détecter les compositions de services inefficaces. Dans une dernière partie, nous abordons la problématique de la détection des goulots d'étranglement dans un réseau de services au travers de l'analyse de centralité du graphe hiérarchique précédent. Ce travail s'appuie sur un programme de simulation qui a aussi été instrumenté avec OpenTelemetry afin d'émettre des données de traçage. Ces traces ont été converties en un graphe de propriétés hiérarchique et une étude sur les algorithmes de centralité a permis d'identifier les points d'étranglement. Les deux approches présentées dans cette thèse utilisent et exploitent l'état de l'art en matière de monitoring des applications Cloud. Elles proposent une nouvelle utilisation des données de "distributed tracing" pas uniquement pour l'investigation et le débogage, mais pour la détection et la réaction automatiques sur un système réel
Cloud Computing has changed how software is now developed and deployed. Nowadays, Cloud applications are designed as rapidly evolving distributed systems that are hosted in third-party data centre and potentially scattered around the globe. This shift of paradigms also had a considerable impact on how software is monitored: Cloud application have been growing to reach the scale of hundreds of services, and state-of-the-art monitoring quickly faced scaling issues. In addition, monitoring tools also now have to address distributed systems failures, like partial failures, configuration inconsistencies, networking bottlenecks or even noisy neighbours. In this thesis we present an approach based on a new source of telemetry that has been growing in the realm of Cloud application monitoring. Indeed, by leveraging the recent OpenTelemetry standard, we present a system that converts "distributed tracing" data in a hierarchical property graph. With such a model, it becomes possible to highlight the actual topology of Cloud applications like the physical distribution of its workloads in multiple data centres. The goal of this model is to exhibit the behaviour of Cloud Providers to the developers maintaining and optimizing their application. Then, we present how this model can be used to solve some prominent distributed systems challenges: the detection of inefficient communications and the anticipation of hot points in a network of services. We tackle both of these problems with a graph-theory approach. Inefficient composition of services is detected with the computation of the Flow Hierarchy index. A Proof of Concept is presented based on a real OpenTelemetry instrumentation of a Zonal Kubernetes Cluster. In, a last part we address the concern of hot point detection in a network of services through the perspective of graph centrality analysis. This work is supported by a simulation program that has been instrumented with OpenTelemetry in order to emit tracing data. These traces have been converted in a hierarchical property graph and a study on the centrality algorithms allowed to identify choke points. Both of the approaches presented in this thesis comply with state-of-the-art Cloud application monitoring. They propose a new usage of Distributed Tracing not only for investigation and debugging but for automatic detection and reaction on a full system

Resumen

The flipside of misogyny’s punishment of women is exonerating the privileged men who engage in misogyny. This chapter canvasses this phenomenon, along with the flow of sympathy up the social hierarchy, away from the female victims of misogyny toward its (again, privileged) male perpetrators. This is dubbed “himpathy.” These phenomena are connected to epistemic injustice and epistemic oppression, theorized by Miranda Fricker and Kristie Dotson, among others. As a contrast with the much-discussed Isla Vista killings, the chapter considers the far less publicized case of the serial rapist police officer in Oklahoma City, who preyed on black women who had criminal records, in the belief that these women would have no legal recourse. This is an instance of systemic “misogynoir”—Moya Bailey’s term for the distinctive, in some ways sui generis form of misogyny to which black women in the United States are subject, given misogyny’s interaction with racism and white supremacy.

Resumen

There are more than 600 Federal district judges serving today, and they decide some 230,000 civil cases each year. About 90% of the decisions they reach are final. Lyles argues that these lower court judges not only influence the flow of information to the judicial hierarchy, but they formulate questions that influence how higher courts, including the Supreme Court, respond. As such they are key elements in the formulation and implementation of public policy. To cite a few examples, they desegregate school districts, run mental institutions and prisons, break up monopolies, and reapportion legislatures. Lyles begins by examining the structure and function of federal courts and detailing the history, operation, and purpose of the district courts. He then turns to the selection, nomination, and appointment of district judges. Lyles then analyzes the extent to which presidents might advance policy objectives through their judicial appointments to the district courts. After examining how African-American, Latino, and white judges, male and female, view their roles as policy actors, Lyles concludes with a discussion of the implications of the study. Important for students and scholars of contemporary public policy and the court system.

Resumen

This collection of essays explores the metaphysical thesis that the living world is not ontologically made up of substantial particles or things, as has often been assumed, but is rather constituted by processes. The biological domain is organized as an interdependent hierarchy of processes, which are stabilized and actively maintained at different timescales. Even entities that intuitively appear to be paradigms of things, such as organisms, are actually better understood as processes. Unlike previous attempts to articulate processual views of biology, which have tended to use Alfred North Whitehead’s panpsychist metaphysics as a foundation, this book takes a naturalistic approach to metaphysics. It submits that the main motivations for replacing an ontology of substances with one of processes are to be looked for in the empirical findings of science. Biology provides compelling reasons for thinking that the living realm is fundamentally dynamic and that the existence of things is always conditional on the existence of processes. The phenomenon of life cries out for theories that prioritize processes over things, and it suggests that the central explanandum of biology is not change but rather stability—or, more precisely, stability attained through constant change. This multicontributor volume brings together philosophers of science and metaphysicians interested in exploring the consequences of a processual philosophy of biology. The contributors draw on an extremely wide range of biological case studies and employ a process perspective to cast new light on a number of traditional philosophical problems such as identity, persistence, and individuality.

Resumen

This chapter provides a background on the Euler-Reynolds system, starting with some of the underlying philosophy behind the argument. It describes low frequency parts and ensemble averages of Euler flows and shows that the average of any family of solutions to Euler will be a solution of the Euler-Reynolds equations. It explains how the most relevant type of averaging to convex integration arises during the operation of taking weak limits, which can be regarded as an averaging process. The chapter proceeds by focusing on weak limits of Euler flows and the hierarchy of frequencies, concluding with a discussion of the method of convex integration and the h-principle for weak limits. The method inherently proves that weak solutions to Euler may fail to be solutions.

Resumen

This chapter explores the representation of gender in UN peacebuilding discourse, developing the argument that the discourse says “gender” but means “women,” meaning that the concept of gender becomes associated with women in not entirely positive and productive ways. The function of these discursive practices is precisely to circumscribe the agency of women and to position the subject of “women” as subordinate to “men” in a hierarchy of gendered power. This construction in turns leads to diminish resource flows to programs and services that cater to women, the exclusion of women from formal and informal political spaces, and the perpetuation of economic, cultural, and political discrimination and violence against women. In these ways, the United Nations is creating not so much “conditions of possibility,” per Foucault, but “conditions of impossibility” structuring gender-responsive peacebuilding at the UN.

Resumen

Food is an important indicator of social differentiation, which defines the boundaries between social groups, and social hierarchy, which entails class, status, and power inequality. Because food is a basic element of material culture and social life, it has occupied a central place in the discipline of anthropology from its earliest days. Anthropologists view food and foodways as tools with which to understand individual cultures and societies, especially when they are situated in the context of global and historical flows and connections. Ethnography, the methodology used by anthropologists and by some other social scientists, relies on a holistic and empathetic approach based on lived experience among the people being studied. Anthropologists have long been interested in commensality as both a source and an expression of group identities. Another way to probe sociality is to analyze gifts and manners.

Resumen

Companies across all industries are engaging in digital transformation to harness the power of advanced information technologies. Building on interviews and diverse case studies, this book describes how data and algorithms are reshaping management practices, organizational structures, corporate culture, and work roles. The book develops a broad framework for understanding digitalization not as a technological change, but as a new normative mindset, ‘the data imperative’. New managerial ideals compel companies to pursue digital omniscience and omnipotence—the abilities to represent and understand the world through real-time data flows and to control customer experiences, physical equipment, and workers with software. The efforts to complement and replace human expertise with data and smart algorithms are associated with shifts in strategic priorities, adoption of powerful modular architectures, new organizational structures, and introduction of artificial intelligence into diverse work roles. Surveying the changes in management and the workplace, this book offers an integrative and balanced account of the ongoing changes. It elaborates how artificial intelligence is changing work at all levels of the hierarchy and envisions how the emerging artificially intelligent organization will change how professionals work. The frameworks and ideas espoused in this book will help the reader understand the ongoing changes in the workplace that affect everyone from executives and professionals to frontline workers.

Resumen

AbstractAccording to new mechanists, mechanisms explain how specific biological phenomena are produced. New mechanists have had little to say about how mechanisms relate to the organism in which they reside. A key feature of organisms, emphasized by the autonomy tradition, is that organisms maintain themselves. To do this, they rely on mechanisms. But mechanisms must be controlled so that they produce the phenomena for which they are responsible when and in the manner needed by the organism. To account for how they are controlled, we characterize mechanisms as sets of constraints on the flow of free energy. Some constraints are flexible and can be acted on by other mechanisms, control mechanisms, that utilize information procured from the organism and its environment to alter the flexible constraints in other mechanisms so that they produce phenomena appropriate to the circumstances. We further show that control mechanisms in living organisms are organized heterarchically—control is carried out primarily by local controllers that integrate information they acquire as well as that which they procure from other control mechanisms. The result is not a hierarchy of control but an integrated network of control mechanisms that has been crafted over the course of evolution.

Resumen

AbstractThe United Nation’s 17 Sustainable development Goals (SDG) can be considered as the lighthouse of the great challenges which humanity will be confronted with. Many of these goals are related to our behaviors and our “take, make, and dispose,” namely, the linear dominant economic model that, in the last centuries, is leading to an ongoing increase of resource consumption and, consequently, a huge generation of waste. In fact, the rate of both natural resource consumption and waste generation are urgent issues, especially in the urban and peri-urban areas that will require proper solutions. The city is and will be even more in the future the most affected and the major drivers of resource consumption since it is expected that by 2050 more than 70% of the population will live in urbanized areas, and cities will grow in number and size. It means that land, water, food, energy, and other natural resource are increasingly necessary, but because resources are limited, it is required to change the linear consumption model in a new circular model of use and consumption where waste is avoided. In the last few years, emerged that waste management practices are improving according to the European Waste Hierarchy guidance, but there is still a wide possibility of improvement. This chapter explores, on one hand, what means the circular city, and on the other hand how to build it suggesting some policy recommendations. Considering urban and peri-urban areas as the space of material and people flows, thus optimizing the space used by flows and improving their interactions, it will be possible to construct another step toward circularity. In that view, the circular city acquires an urban and territorial perspective that can be managed with the urban and territorial tools, measures, policies, and plans, able to link also issues like climate adaptation, resilience, and sustainability. Finally, we argue that important work must be done in the immediate future in order to re-think and re-design urban spaces, urban practices, and infrastructures, thus shift from linear to circular city.

Resumen

River ecosystems are highly dependent on and responsive to hydrologic variability over multiple time scales (e.g., hours, months, years). Fluctuating river flows present a key challenge to river managers, who must weigh competing demands for freshwater. Environmental flow recommendations and regulations seek to provide management targets balancing socio-economic outcomes with maintenance of ecological integrity. Often, flow management targets are based on average river conditions over temporal windows such as days, months, or years. Here, three case studies of hydrologic variability are presented at each time scale, which demonstrate the potential pitfalls of mean-based environmental flow criteria. Each case study shows that the intent of the environmental flow target is not met when hydrologic variability is considered. While mean discharge is inadequate as a single-minded flow management target, the consequences of mean flow prescriptions can be avoided in environmental flow recommendations. Based on these case studies, a temporal hierarchy of environmental flow thresholds is proposed (e.g., an instantaneous flow target coupled with daily and monthly averages), which would improve the efficacy of these regulations.
