The process of downsizing a mental health hospital : an ethnography
Creators: name: Sage-Hayward, Wendy S.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the study was to identify and describe the approach and strategies used to downsize a mental health organization. This ethnographic study was conducted at a psychiatric hospital that is beginning the 4th year of a 10 year downsizing plan. Data were gathered through interviews, informal observations, and field documents. This research design facilitated an understanding of the phenomenon in the context of the practices and beliefs of the executive management team. Semistructured interviews were conducted with six executive and four middle managers who were involved in the downsizing decision making process. Freeman and Cameron's (1993) definition of downsizing was broadened to encompass not-for-profit reasons for downsizing. Cameron's (1994) downsizing model was supported and an additional best practice called alignment of purpose was proposed in which the leadership of an organization attempts to align the stakeholders with similar goals and objectives for downsizing. The emotional process of downsizing emerged as a key area to address concurrently with job security and other more pragmatic consequences of downsizing. Empathy was suggested as one method of dealing with the emotional process of downsizing.

description: The paper traces the debate that emerged during the "Mediterranean Urban Design & Regeneration Event" at the Italian Pavilion of Dubai Expo 2020, in which a representative of the Department of Architecture ("Gabriele d'Annunzio" University of Chieti-Pescara), together with Middle Eastern universities, discussed the future of public spaces in Dubai, retracing the history of its urban development and outlining strategic guidelines for the regeneration of some pilot areas, identified in the consolidated urban fabric. This initiative was promoted by the Ministry of Foreign Affairs and International Cooperation, following a call for proposals on the topic "Connecting Minds, Creating the Future", a focus on aspects related to opportunities, mobility sustainability both from a material point of view (infrastructures and environmental resources), and from an intangible point of view, through the sharing of creative content and experiences and the dissemination of innovative cultural and scientific projects.
Through online meetings (including with partners from the schools of architecture and engineering in Dubai and Abu Dhabi) and then over the course of six in-person panel discussions, our proposed intensive workshop sought to spark a dialogue between two different approaches to urban design, the Mediterranean and the Middle Eastern, using the context of Dubai, the global capital of capitalism and neoliberal urbanism, as a kind of "stress test" for the concept of public open space.

description: Σκοπός της διατριβής ήταν η διερεύνηση ζητημάτων που αναφύονται πάνω στην τομή υποκειμενικής ταυτότητας και ευθύνης, στην σύγχρονη νεωτερικότητα. Στα πλαίσια αυτά, εξετάστηκε η μετανεωτερική στάση απέναντι στη διαμόρφωση της ανθρώπινης υποκειμενικότητας και την υπόθεση της κοινωνικής προόδου, σε αντιπαραβολή με την λεγόμενη κληρονομημένη σκέψη της κλασικής νεωτερικότητας. Καταδείχθηκαν ιδιαίτερα οι τρόποι υποκειμενοποίησης σήμερα, τρόποι βασισμένοι στην ιδέα του «αποκεντροποιημένου» υποκειμένου και παράλληλα, σε αντιδιαστολή παρουσιάστηκαν μια σειρά “Λόγων”, οι οποίοι διεκδικούν να νοηματοδοτήσουν το πεδίο της υποκειμενικότητας και να αρθρώσουν για λογαριασμό του υποκειμένου, έναν κανονιστικό λόγο που το αφήνει απ΄έξω, ενώ καταπνίγουν τη διαφορά. Συγκεκριμένα, εξετάσαμε το ρόλο της πολιτικής εξουσίας, η οποία αποτελεί ένα πεδίο ταυτίσεων για το υποκείμενο, με ιδεολογίες που εγγράφονται στη γλώσσα και εσωτερικεύονται από το υποκείμενο, αποσπώντας την συναίνεσή του, με έναν τρόπο που δεν γίνεται αντιληπτός από το ίδιο. Όλη η προβληματική της υποκειμενικότητας και ευθύνης στην ύστερη νεωτερικότητα, στον βασικό κορμό της διατριβής, εξετάζεται μέσα από την παρουσίαση δυο θεωριών για την υποκειμενικότητα, του Κορνήλιου Καστοριάδη και της Judith Butler.
description: The purpose of the present thesis was the study of issues arising over the intersection of subjective identity and responsibility in contemporary modernity. In this context, we examined the postmodern attitude towards the formation of human subjectivity and the cause of social progress, in comparison with the so-called inherited thought of classical modernity. We particularly demonstrated, the ways of subjectification today, that are based on the idea of "the decentralized" subject while, in contrast presented a series of "discourses", who claim to sense-field of subjectivity and to articulate on behalf of the subject, one reason that the regulatory leaves it outside, while stifling the difference. Specifically, we examined the role of Political Power, which is a field of identifications of the subject, with ideologies entered in the field of Language and internalized by the subject, receiving the consent, in a way that is not perceived by itself. The whole issue of subjectivity and responsibility in late modernity, in the core of the Thesis is examined by presenting two Τheories on the field of subjectivity, of Cornelius Castoriadis and Judith Butler.
Green infrastructure and urban design as an adaptation strategy

Publisher: name: UPLanD - Journal of Urban Planning, Landscape & environmental Design
Year: 2023

description: The essay intends to spread the scientific importance of the relationship between environment and built space, focusing on the green space of the city that conceived as a green infrastructure (Green Infrastructure GI) can contribute to improving the quality of natural capital, to the well-being of men and ensuring biodiversity and improving urban resilience to extreme phenomena. In particular, the aim is to deepen the meaning of the term GI, an analysis of the policies that encourage and enhance its use. The intention is to extrapolate the fundamental characteristics including the multifunctional aspect, which attributes the ability to improve ecosystem services and therefore contain the vulnerability and increase the resilience of the urban system. Environmental design can define the boundaries and determine limits and goals related to the complex relationship between inhabitants and the environment and solve it in the valorization of GI. Starting from these considerations it tries to answer how governance policies at the local level acknowledge the importance of the GI, and through some contemporary examples an explanation of the urban project strategies that allow their applicability in response to the challenges of the climate changes.

description: Cobalt oxide superconductor NaxCoO2.yH2O is studied by angle-resolved photoemission spectroscopy (ARPES). We report the Fermi surface (FS) topology and electronic structure near the Fermi level (EF) of NaxCoO2.yH2O. Our result indicates the presence of the hexagonal FS centered at G point, while the small pocket FSs along G-K direction are absent similar to NaxCoO2. The top of the eg' band, which is expected in band calculations to form the small pocket FSs, extends to within 20 - 50 meV below EF, more closer to EF than in NaxCoO2. We discuss its possible role in superconductivity, comparing with other experimental and theoretical results.

description: A potassium-ion electret, which is a key element of vibration-powered microelectromechanical generators, can store negative charge almost permanently. However, the mechanism by which this negative charge is stored is still unclear. We theoretically study the atomic and electronic structures of amorphous silica (a-SiO2) with and without potassium atoms using first-principles molecular-dynamics calculations. Our calculations show that a fivefold-coordinated Si atom with five Si-O bonds (an SiO5 structure) is the characteristic local structure of a-SiO2 with potassium atomsm, which becomes negatively charged and remains so even after removal of the potassium atoms. These results indicate that this SiO5 structure is the physical origin of the robust negative charge observed in potassium-ion electrets. We also find that the SiO5 structure has a Raman peak at 1000cm-1.

Year: 2023

description: The National Recovery and Resilience Plan, together with the European Green Deal and the new Leipzig Charter on sustainable cities, has set the "green" transition as a reference for implementing interventions aimed at reducing carbon emissions. This transition was further strengthened in 2022 by REPowerEU, which includes measures on energy savings, diversification of energy supplies, and an accelerated roll-out of renewable energy to replace fossil fuels in homes, industry, and power generation. In response, large cities with populations over 50’000 have accelerated their transition by implementing adaptation and mitigation actions to climate change, in line with the European vision of achieving "net-zero emissions by 2050". However, the contribution of small municipalities (i.e., those with populations below 10’000) towards achieving this vision has only been partially considered. This research aims to highlight the role of small municipalities in achieving the net-zero emissions vision through the European initiative of the Covenant of Mayors for Climate and Energy (CoM). In this research, the actions developed by the small Italian CoM municipalities were analyzed, remarking some relevant best practices. The proposed evaluation highlights the effectiveness of the actions in reducing carbon emissions and promoting sustainable development. The findings of this research represent a contribution in supporting the implementation of decision-making process and identify best practices that can be replicated in other small municipalities.

description: This paper refers to the key issues of the crime of fraud, which is criminalized at article 386 of the Penal Code. The crime of fraud is a particularly complicated one and the interpretation of certain issues has divided both academics and case law. Initially, the legally protected good of property is examined and the relevant theories are presented. Then, the objective side of the crime is analyzed, through the presentation and interpretation of the deceptive conduct of the offender and the consecutive results that are included in the actus reus. Particular emphasis is given to the crucial concept of fact. Furthermore, the mens rea and particularly the required additional purpose are examined. Finally, after references to matters of attempt and accessory, certain characteristic cases of concurrence are presented.
Collimation, Proper Motions, and Physical Conditions in the HH 30 Jet From HST Slitless Spectroscopy

description: We present Space Telescope Imaging Spectrograph (STIS) spectral images of the HH~30 stellar jet taken through a wide slit over two epochs. The jet is unresolved spectrally, so the observations produce emission-line images for each line in the spectrum. This rich dataset shows how physical conditions in the jet vary with distance and time, produces precise proper motions of knots within the jet, resolves the jet width close to the star, and gives a spectrum of the reflected light from the disk over a large wavelength range at several positions. We introduce a new method for analyzing a set of line ratios based on minimizing a quadratic form between models and data. The method generates images of the density, temperature and ionization fraction computed using all the possible line ratios appropriately weighted. In HH 30, the density declines with distance from the source in a manner consistent with an expanding flow, and is larger by a factor of two along the axis of the jet than it is at the periphery. Ionization in the jet ranges from ~ 5% to 40%, and high ionization/excitation knots form at about 100 AU from the star and propagate outward with the flow. These high-excitation knots are not accompanied by corresponding increases in the density, so if formed by velocity variations the knots must have a strong internal magnetic pressure to smooth out density increases while lengthening recombination times.

description: We present 1.5D Vlasov code simulations of the dynamics of electron holes in non-uniform magnetic and electric fields typical of current sheets and, particularly, of the Earth's magnetotail current sheet. The simulations show that spatial width and amplitude of electron holes do not substantially vary in the course of propagation, but there arises a double layer localized around the electron hole and manifested as a drop of the electrostatic potential along the electron hole. We demonstrate that electron holes produced around the neutral plane of a current sheet slow down in the course of propagation toward the current sheet boundaries. The leading contribution to electron hole braking is provided by the non-uniform magnetic field, though electrostatic fields typical of the current sheets do provide a noticeable contribution. The simulations also show that electron holes with larger amplitudes are slowed faster. The simulation results suggest that some of slow electron holes recently reported in the Earth's plasma sheet boundary layer may appear due to braking of initially fast electron holes in the course of propagation in the current sheet.
Exploring the dream life of First Nations children from recovering alcoholic homes

Publisher: name: University of British Columbia

description: In studying the dreams of First Nations children, I honoured Native culture through gaining knowledge to plan for future generations and by acknowledging dreams, I hoped to revive the Native belief that empowerment and guidance could be obtained from dreams. The literature on children's dreams and the experiences of children of alcoholics was minimal. In this qualitative exploratory study, I analyzed the dreams of a Native boy and girls between the ages of 9 and 13. The child participants were from home environments where the mother was recovering from alcoholism. I examined the dreamer's perceptions in the dreams collected and the results indicated that dreams did not reveal direct evidence of alcohol, or First Nations themes. The dreams however did expose other issues that the children were dealing with, which were sometimes connected to alcoholism. Some of these concerns were: domestic violence, neglect, and abuse. Along with these grave issues, the children also dealt with less serious concerns in their dreams, such as quarrels with friends. The children's resiliency varied, individually, according to their dream perceptions of themselves, and others. The findings suggest that collecting a series of dreams could enable a counsellor to gain information about the child's situation that the child may not otherwise convey. This assessment from dreams can assist in planning interventions for the child and family.

description: We discuss the Palatini formulation of modified gravity including a Yukawa-like term. It is shown that in this formulation, the Yukawa term offers an explanation for the current exponential accelerated expansion of the universe and reduces to the standard Friedmann cosmology in the appropriate limit. We then discuss the scalar-tensor formulation of the model as a metric theory and show that the Yukawa term predicts a power-law acceleration at late-times. The Newtonian limit of the theory is also discussed in context of the Palatini formalism.

We use a multivariate extension of Szego's theorem to show the existence of the mean Chernoff and Hoeffding bounds and the mean relative entropy, and show that these quantities arise as the optimal error exponents in suitable settings.

Year: 2023

description: The contemporary city is currently experiencing a transition between a phase of growth and expansion and one of stasis or decline in most of the urban contexts of economically developed countries. This transition is also connected to the urban shrinkage phenomenon which arose at the beginning of the century, due to the economic and demographic crisis, and is radically changing the consolidated city' shapes and uses. The aleatory nature of material and immaterial manifestations of an occurrence like urban shrinkage and the inadequacy of a planner's “tools”, when facing the challenge to work on the city at loss, leads to identify the flexibility of urban plans as one of the most suitable and structural response to this type of city's condition. In such a context, the contribution aims to investigate how reversibility in urban planning, it is intended not only as the change of an object’ state from its current state, but also as the possibility of the object's return to its prior state before a certain event occurred as in the case of "downgrading" from urban to non-urban uses.
Through a comparative examination of the regional legislative framework, the article outlines the main aspects of reversibility of urban planning in the Italian context, eventually highlighting some attention points.

description: The effective action in quantum general relativity is strongly dependent on the gauge-fixing and parametrization of the quantum metric. As a consequence, in the effective approach to quantum gravity, there is no possibility to introduce the renormalization-group framework in a consistent way. On the other hand, the version of effective action proposed by Vilkovisky and DeWitt does not depend on the gauge-fixing and parametrization off-shell, opening the way to explore the running of the cosmological and Newton constants as well as the coefficients of the higher-derivative terms of the total action. We argue that in the effective framework the one-loop beta functions for the zero-, two- and four-derivative terms can be regarded as exact, that means, free from corrections coming from the higher loops. In this perspective, the running describes the renormalization group flow between the present-day Hubble scale in the IR and the Planck scale in the UV.

description: For children displaced from conflict, attending school can be a lifeline, providing stability, learning and opportunities for socialisation. In such contexts, teachers become more than facilitators of learning as they find themselves providing social-emotional support and guidance to traumatised students and their families. Yet, teachers of refugees and other vulnerable children are often the least supported, compromising their ability to teach effectively and provide high-quality education to students. This is the case in Jordan where most Syrian refugees are taught by temporary contract teachers (TCTs), who are Jordanian nationals and typically begin teaching with little to no training or classroom experience. Although nearly all hold bachelor degrees, TCTs are precariously employed and usually paid the national minimum wage, which is a fraction of the salaries their permanently employed counterparts receive.This study’s overall research objective was to understand the effects of current hiring, training and evaluation policies and practices on TCTs’ motivation to work and their perceptions of teacher management policies, system practices and working conditions in Jordan. The study is primarily descriptive in that it assesses TCTs’ perspectives and needs, current practices and possible solutions, laying the groundwork for intervention design and testing in a later phase. The following research questions (RQs) guided the study:RQ1: What are TCTs’ motivations, challenges and experiences with hiring processes (recruitment, selection and deployment) under the current policies?RQ2: What are TCTs’ motivations, challenges and experiences with the application (or lack thereof) of current teacher evaluation and training protocols and practices?RQ3: What interventions (strategy, policy or programme) do teachers and system-level stakeholders perceive to be desirable and potentially cost-effective and scalable to improve motivation, management and support?While an associated technical brief focuses on the quantitative findings1 of the study, this brief focuses on the outcomes of the qualitative components of the study and hence focuses on the qualitative sample and results, which relate to research question 3.

description: We have fabricated Na_xCoO_2 thin films via lateral diffusion of sodium into Co_3O_4 (111) epitaxial films (reactive solid-phase epitaxy: Ref. 4). The environment of thermal diffusion is key to the control of the sodium content in thin films. From the results of x-ray diffraction and in-plane resistivity, the epitaxial growth and the sodium contents of these films were identified. The thermoelectric measurements show a large thermoelectric power similar to that observed in single crystals. The quasiparticle scattering rate is found to approach zero at low temperatures, consistent with the small residual resistivity, indicating high quality of the Na_xCoO_2 thin films.

Through and beyond the Poli(s)crisis: Guiding the Eco-Social Transition in UE
Creators: name: Pultrone, Gabriella
Publisher: name: UPLanD - Journal of Urban Planning, Landscape & environmental Design
Year: 2023

description: The word crisis indicates a polysemic concept that has become pervasive following the Covid-19 emergency. If it is essential to know how to manage emergencies, it is undoubtedly a priority to increase the resilience of cities, territories, and communities with innovative projects for a fair and sustainable future beyond crises, to adequately face the priority challenge of climate change. The ongoing polychrisis (health, economic, ecological, political, social, cultural, spiritual) can therefore be considered a driver that has triggered an acceleration in the process of ecological, social, energy and digital transition at the heart of EU policies.
The word poli(s)crisis, instead of the literal translation polychrisis, highlights the central and decisive dual role of cities as a sphere of concentration and amplification of the crisis and, at the same time, a privileged sphere of experimentation and acceleration of the aforementioned multiple transition process underway. Indeed, internationally, many cities are rethinking urban space promoting inclusive planning and the importance of Nature-Based Solutions (NBSs) that can increase environmental value across the urban-rural continuum with an integrated approach. Therefore, referring to some case studies in the EU panorama, the article aims to highlight the inevitable need to pursue the goals of eco-social transition by integrating NBSs into multi-level planning and regeneration strategies.

This is enabled by high harmonic generation of two temporally delayed driving pulses, resulting in a tuning range of 0.8 eV at the 19th harmonic at 22.8 eV. The implemented approach allows for fast tuning of the spectrum, is highly flexible and is scalable towards full spectral coverage at higher photon energies.

We found that any system (without monopoles) admitting the separation of variables in the elliptic or parabolic coordinates can be extended to the integrable system with the Dirac monopoles located at the foci of the corresponding coordinate systems. Particular cases of this class of system are the two-center MICZ-Kepler system in the Euclidean space, the limiting case when one of the background dyons is located at the infinity as well as the model of particle in parabolic quantum dot in the presence of parallel constant uniform electric and magnetic fields.

description: The aim of the paper is to point out the role of resilient public spaces in ensuring public health and safety in the time of pandemic and in multi-risk scenarios. The investigation of urban strategies – that guarantee accessibility and flexibility of public spaces – is framed in opposition to the policies of closure and forbiddance of use which have largely been applied during the COVID-19 pandemic in the years 2020-2022, especially in Italy. Through a review of current policies on the topic of multi-risk exposure and emergency management at the global, European, national, and local level (with the case of the Campania Region, in South Italy), the paper underlines the weaknesses of urban planning and design instances in emergency decision-making processes. A selection of initiatives that experimented new spatial uses and configurations of public spaces is used to reflect on how recent practices reacted to the pandemic, as an alternative to restrictive, non-resilient approaches. The results are discussed and interpreted as relevant components to build back better, reinterpreting the role of public spaces towards an innovative research agenda for more sustainable and resilient planning and design.

description: In the last centuries, urban areas have been increasingly facing climate change-related thermal stresses and extreme events. Within this context, soil de-sealing might become a relevant part of urban adaptation processes, as well as an opportunity to activate citizens’ participation, in a bottom-up logic that virtuously integrates top-down interventions.
This paper reflects on the outcomes of the applied research experiences with Third Mission traits carried out within the project “Green in Parma”, with the purpose to investigate the role of soil de-sealing in participatory processes, and to face the impacts of climate change with a bottom-up logic. These experiences allowed to gain insight about the role of academic research in this context and to link it to the more traditional Italian top-down urban planning tools.
“Green in Parma” was promoted in 2021 by voluntary organizations, private companies, and the University of Parma. The initiative can be divided into a first dissemination module about the multifunctional benefits of green at urban scale, followed by a participatory and co-design module which aims at a bottom-up desealing intervention. Within this second module, several activities are taking place or are being planned.
This contribution presents the first phases of these applied experiences, as well as a discussion about the first results and some of the outcomes of the questionnaire proposed to the citizens of Parma on their perception of the local climate change effects.

description: We review recent results concerning the renormalization group (RG) transformation of Dyson's hierarchical model (HM). This model can be seen as an approximation of a scalar field theory on a lattice. We introduce the HM and show that its large group of symmetry simplifies drastically the blockspinning procedure. Several equivalent forms of the recursion formula are presented with unified notations. Rigorous and numerical results concerning the recursion formula are summarized. It is pointed out that the recursion formula of the HM is inequivalent to both Wilson's approximate recursion formula and Polchinski's equation in the local potential approximation (despite the very small difference with the exponents of the latter). We draw a comparison between the RG of the HM and other RG equations in the local potential approximation. The construction of the linear and nonlinear scaling variables is discussed in an operational way. We describe the calculation of non-universal critical amplitudes in terms of the scaling variables of two fixed points. This question appears as a problem of interpolation between these fixed points. Universal amplitude ratios are calculated. We discuss the large-N limit and the complex singularities of the critical potential calculable in this limit. The interpolation between the HM and more conventional lattice models is presented as a symmetry breaking problem. We briefly introduce models with an approximate supersymmetry. One important goal of this review article is to present a configuration space counterpart, suitable for lattice formulations, of other RG equations formulated in momentum space (sometimes abbreviated as ERGE).

description: Low propagation loss in high confinement waveguides is critical for chip-based nonlinear photonics applications. Sophisticated fabrication processes which yield sub-nm roughness are generally needed to reduce scattering points at the waveguide interfaces in order to achieve ultralow propagation loss. Here, we show ultralow propagation loss by shaping the mode using a highly multimode structure to reduce its overlap with the waveguide interfaces, thus relaxing the fabrication processing requirements. Microresonators with intrinsic quality factors (Q) of 31.8 $\pm$ 4.4 million are experimentally demonstrated. Although the microresonators support 10 transverse modes only the fundamental mode is excited and no higher order modes are observed when using nonlinear adiabatic bends. A record-low threshold pump power of 73 $μ$W for parametric oscillation is measured and a broadband, almost octave spanning single-soliton frequency comb without any signatures of higher order modes in the spectrum spanning from 1097 nm to 2040 nm (126 THz) is generated in the multimode microresonator. This work provides a design method that could be applied to different material platforms to achieve and use ultrahigh-Q multimode microresonators.

description: For children displaced from conflict, attending school can be a lifeline, providing stability, learning and opportunities for socialisation. In such contexts, teachers become more than facilitators of learning as they find themselves providing social-emotional support and guidance to traumatised students and their families. Yet, teachers of refugees and other vulnerable children are often the least supported, compromising their ability to teach effectively and provide high-quality education to students. This is the case in Jordan where most Syrian refugees are taught by temporary contract teachers (TCTs), who are Jordanian nationals and typically begin teaching with little to no training or classroom experience. Although nearly all hold bachelor degrees, TCTs are precariously employed and usually paid the national minimum wage, which is a fraction of the salaries their permanently employed counterparts receive.This study’s overall research objective was to understand the effects of current hiring, training and evaluation policies and practices on TCTs’ motivation to work and their perceptions of teacher management policies, system practices and working conditions in Jordan. The study is primarily descriptive in that it assesses TCTs’ perspectives and needs, current practices and possible solutions, laying the groundwork for intervention design and testing in a later phase. The following research questions (RQs) guided the study:● RQ1: What are TCTs’ motivations, challenges and experiences with hiring processes (recruitment, selection and deployment) under the current policies?● RQ2: What are TCTs’ motivations, challenges and experiences with the application (or lack thereof) of current teacher evaluation and training protocols and practices?● RQ3: What interventions (strategy, policy or programme) do teachers and system-level stakeholders perceive to be desirable and potentially cost-effective and scalable to improve motivation, management and support?While an associated technical brief focuses on the qualitative findings of the study, this technical brief focuses on the quantitative findings
Misty water coloured misogyny : The politics of "false memory syndrome"
Creators: name: Webb, Annabel N.
Publisher: name: University of British Columbia

description: Over the past 20 years feminism has clearly altered popular consciousness about sexual abuse and record numbers of women have come forward to expose the men who sexually assaulted them. It is in this context that the notion of false memory syndrome (FMS) has arisen signifying a debate about the scientific validity of repression and memory of sexual abuse. In order to challenge the notion of FMS, which I argue in part of a right wing attack against feminism, and particularly in the psychotherapeutic realm, I critically analyze 4 volumes of False Memory Syndrome Foundation Newsletters. I argue that the False Memory Syndrome Foundation, a Pennsylvania based lobby group, masterminded the notion of FMS as part of a political and legal strategy to deny women's allegations of sexual abuse against powerful white men. I argue further that this movement employs rhetoric and organizing tactics that are consistent with neoconservative movements more generally.
title: The Effects of Communicating Inflation Uncertainty on Household Expectations

description: This paper examines the value of direct communication to households about inflation and the uncertainty around inflation statistics. All types of information about inflation are effective at immediately managing inflation expectations, with information about outlooks being more effective and more relevant than that about recent inflation and Bank targets. We observe no downside to communicating about inflation with uncertainty on two measures: the level of expected inflation and uncertainty about it. On a third measure—probabilistic inflation expectations—we observe positive effects: they become more centered around the communicated ranges. However, communication with uncertainty weakens the link between expected inflation and spending plans, a key channel in the transmission of monetary policy. Communicating precise inflation outlooks can lengthen the effects of these communications on households.
description: Cette étude examine la valeur d’une communication directe avec les ménages au sujet de l’inflation et de l’incertitude entourant les statistiques sur l’inflation. Toute information sur l’inflation permet de gérer immédiatement les attentes, mais l’information sur les perspectives est plus efficace et plus pertinente que celle sur la tenue récente de l’inflation et les cibles de la Banque. Selon nos observations, la communication de données sur l’inflation empreintes d’incertitude n’a aucun effet négatif sur les deux mesures suivantes : le niveau d’inflation attendu et l’incertitude entourant l’inflation. Sur une troisième mesure – les attentes probabilistes relativement à l’inflation –, nous constatons des effets positifs : ces attentes se concentrent davantage autour des fourchettes communiquées. Toutefois, le fait de communiquer des données empreintes d’incertitude affaiblit le lien entre l’inflation anticipée et les dépenses prévues, un important canal de transmission de la politique monétaire. Par ailleurs, la communication de perspectives d’inflation précises peut prolonger les effets de ces messages sur les ménages.
