description: We perform the BFV quantization of the 2+1 projectable and the 3+1 nonprojectable versions of the Horava theory. This is a Hamiltonian formalism, and noncanonical gauges can be used with it. In the projectable case, we show that the integration on canonical momenta reproduces the quantum Lagrangian known from the proof of renormalization of Barvinsky et al. This quantum Lagrangian is nonlocal, its nonlocality originally arose as a consequence of getting regular propagators. The matching of the BFV quantization with the quantum Lagrangian reinforces the program of quantization of the Horava theory. We introduce a local gauge-fixing condition, hence a local Hamiltonian, that leads to the nonlocality of the Lagrangian after the integration. For the case of the nonprojectable theory, this procedure allows us to obtain the complete (nonlocal) quantum Lagrangian that takes into account the second-class contraints. We compare with the integration in general relativity, making clear the relationship between the underlying anisotropic symmetry of the Horava theory and the nonlocality of its quantum Lagrangian.

An evaluation of a human relations training program for engineers
Creators: name: Wilson, Blair
Publisher: name: University of British Columbia
Year: 2010

description: Engineers have been presented, almost traditionally, as highly skilled specialists who tend to lack skills in the human relations area. This study evaluated a human relations training program for engineers which had been developed to fill the gap in their earlier training. The program is part of the Diploma in Administration for Engineers offered by the British Columbia Council on Continuing Education for Engineers in conjunction with the University of British Columbia. Three instruments were used in the study, namely the Leadership Opinion Questionnaire (LOQ), the Leadership: Employee Orientation and Differentiation Questionnaire (LEAD) and the Profile of Organizational Characteristics (Form-S). The LOQ is a well-established instrument which measures two variables identified as Consideration (C) and Structure (S). The LEAD instrument is relatively new and measures two variables, identified as Employee Orientation (E) and Differentiation (D), which are purported to be similar to the LOQ variables. The Form-S instrument was developed to establish profiles of the characteristics of an organization. On this study, it measured the subjects' perception of their organization at the time of the course (N = Now) and as they wanted it to be (L = Like). Matched control and experimental groups of engineers and technically-oriented personnel, each with fifteen subjects, were selected at a location in Northern British Columbia. The experimental group was exposed to approximately twenty-four hours of total course time, in two weekends spaced one month apart, of a structured human relations training course. The control group was not exposed to any training. Seven hypotheses were tested to determine the effects of the training course on the six variables of the LOQ, LEAD and Form-S instruments. Specifically, a positive increase for the C and E means of the experimental group was expected together with a positive correlation between these two variables. In addition, S and D for both the experimental and control groups were expected to remain unchanged and the two variables were expected to show positive correlation.
Superdevelopments for Weak Reduction

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: We study superdevelopments in the weak lambda calculus of Cagman and Hindley, a confluent variant of the standard weak lambda calculus in which reduction below lambdas is forbidden. In contrast to developments, a superdevelopment from a term M allows not only residuals of redexes in M to be reduced but also some newly created ones. In the lambda calculus there are three ways new redexes may be created; in the weak lambda calculus a new form of redex creation is possible. We present labeled and simultaneous reduction formulations of superdevelopments for the weak lambda calculus and prove them equivalent.
Portuguese women para-troop nurses (1961-1980)
Creators: name: Pereira, Américo
Publisher: name: Gaudium Sciendi
Year: 2022

description: Portugal had a group of military Para-Troop women composed by trained Nurses, whose main mission was to respond to evacuation calls for wounded soldiers, nursing them, keeping them alive until they could reach military hospitals in the rear. The idea, the path to convincing the men in power, the creation and development of this very small but very significant and effective force, along with the service it delivered, constitute a dramatic historical and noble part of the Portuguese Colonial War. The action of these paradigmatic women proved, beyond any honest doubt, the capacity of apparently common women to perform even the harshest and most difficult tasks, never losing, in their case, the profound sense of humane action that had been the ethic core of their formation as Nurses.

A Hybrid Science-Guided Machine Learning Approach for Modeling and Optimizing Chemical Processes

Year: 2021
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: This study presents a broad perspective of hybrid process modeling and optimization combining the scientific knowledge and data analytics in bioprocessing and chemical engineering with a science-guided machine learning (SGML) approach. We divide the approach into two major categories. The first refers to the case where a data-based ML model compliments and makes the first-principle science-based model more accurate in prediction, and the second corresponds to the case where scientific knowledge helps make the ML model more scientifically consistent. We present a detailed review of scientific and engineering literature relating to the hybrid SGML approach, and propose a systematic classification of hybrid SGML models. For applying ML to improve science-based models, we present expositions of the sub-categories of direct serial and parallel hybrid modeling and their combinations, inverse modeling, reduced-order modeling, quantifying uncertainty in the process and even discovering governing equations of the process model. For applying scientific principles to improve ML models, we discuss the sub-categories of science-guided design, learning and refinement. For each sub-category, we identify its requirements, advantages and limitations, together with their published and potential areas of applications in bioprocessing and chemical engineering.We also present several examples to illustrate different hybrid SGML methodologies for modeling polymer processes.

description: We report new precision p(e,e' pi+})n measurements in the Delta(1232) resonance at Q2 = 0.127(GeV/c)2 obtained at the MIT-Bates Out-Of-Plane scattering facility. These are the lowest, but non-zero, Q2 measurements in the pi+ channel. The data offer new tests of the theoretical calculations, particularly of the background amplitude contributions. The chiral effective field theory and Sato-Lee model calculations are not in agreement with this experiment.
Jet-Medium Interactions with Identified Particles

Subjects: subject: Nuclear Experiment (nucl-ex)

description: Identified particles have long been of great interest at RHIC in large part because of the baryon/meson differences observed at intermediate $p_T$ and the implications for hadronization via quark coalescence. With recent high statistics data identified particles are also now central to understanding the details of the jet-medium interactions and energy loss and hadron formation at intermediate and high $p_T$. In particular, high $p_T$ identified particle spectra along with two-particle correlations triggered with direct photons, neutral pions or electrons from heavy flavor decay with hadrons can provide information about how medium modifications to jet fragmentation depend on parton type. I will review recent results with identified particles both in heavy ion systems and the reference measurements in p+p collisions.

description: Spitzer and Caltech Submillimeter Observatory (CSO) images and spectrophotometry of epsilon Eridani at wavelengths from 3.5 to 350 um reveal new details of its bright debris disk. The 350 um map confirms the presence of a ring at r = 11-28 arcsec (35-90 AU) observed previously at longer sub-mm wavelengths. The Spitzer mid- and far-IR images do not show the ring, but rather a featureless disk extending from within a few arcsec of the star across the ring to r ~ 34 arcsec (110 AU). The spectral energy distribution (SED) of the debris system implies a complex structure. A model constrained by the surface brightness profiles and the SED indicates that the sub-mm ring emission is primarily from large (a ~ 135 um) grains, with smaller (a ~ 15 um) grains also present in and beyond the ring. The Spitzer IRS and MIPS SED-mode spectrophotometry data clearly show the presence of spatially compact excess emission at lambda > 15 um that requires the presence of two additional narrow belts of dust within the sub-mm ring's central void. The innermost belt at r ~ 3 AU is composed of silicate dust. A simple dynamical model suggests that dust produced collisionally by a population of about 11 M_Earth of planetesimals in the sub-mm ring could be the source of the emission from both in and beyond the sub-mm ring. Maintaining the inner belts and the inner edge to the sub-mm ring may require the presence of three planets in this system including the candidate radial velocity object.

description: Older adults suffering from serious psychological distress (SPD) have higher health care utilization and expenditures. However, it is unknown whether living alone might further amplify differences in health care usage and costs among older adults with SPD. Using pooled data from 2007-2019 Medical Expenditure Panel Survey, we estimated the incremental care expenditures and utilization associated with SPD among older adults living alone and living with others. The results show that in both living arrangements, having SPD is associated with increases in emergency department visits, hospital admissions, and prescription fill-ups, which leads to higher total prescription expenditures. However, the incremental differences of SPD-related incremental usage and expenditures between older adults living alone and living with others were similar. Our findings call for targeted community programs for older adults that go beyond eliminating physical loneliness, and innovative care coordination strategies that prioritize mental health and preventative care among older adults.

description: The random-field Ising model (RFIM), one of the basic models for quenched disorder, can be studied numerically with the help of efficient ground-state algorithms. In this study, we extend these algorithm by various methods in order to analyze low-energy excitations for the three-dimensional RFIM with Gaussian distributed disorder that appear in the form of clusters of connected spins. We analyze several properties of these clusters. Our results support the validity of the droplet-model description for the RFIM.

description: In this article we study the spectrum of totally geodesic surfaces of a finite volume hyperbolic 3-manifold. We show that for arithmetic hyperbolic 3-manifolds that contain a totally geodesic surface, this spectrum determines the commensurability class. In addition, we show that any finite volume hyperbolic 3-manifold has many pairs of non-isometric finite covers with identical spectra. Forgetting multiplicities, we can also construct pairs where the volume ratio is unbounded.

description: A high order linear $q$-difference equation with polynomial coefficients having $q$-Hahn multiple orthogonal polynomials as eigenfunctions is given. The order of the equation is related to the number of orthogonality conditions that these polynomials satisfy. Some limiting situations when $q\to1$ are studied. Indeed, the difference equation for Hahn multiple orthogonal polynomials given in \cite{Lee} is corrected and obtained as a limiting case.

description: A theory of citations should not consider cited and/or citing agents as its sole subject of study. One is able to study also the dynamics in the networks of communications. While communicating agents (e.g., authors, laboratories, journals) can be made comparable in terms of their publication and citation counts, one would expect the communication networks not to be homogeneous. The latent structures of the network indicate different codifications that span a space of possible 'translations'. The various subdynamics can be hypothesized from an evolutionary perspective. Using the network of aggregated journal-journal citations in Science & Technology Studies as an empirical case, the operation of such subdynamics can be demonstrated. Policy implications and the consequences for a theory-driven type of scientometrics will be elaborated.

description: The article focuses on trajectory design to the trans-Neptunian object (90377) Sedna for launch in 2029-2034. Sedna is currently moving to the perihelion at a distance of around 74 au from the Sun. The perihelion passage is estimated to be in 2073-74. That opens up of opportunities to study such a distant object. Known for its orbit and 10 thousand year period, Sedna is an exciting object for deep space exploration. The current research provides two possible scenarios of transfer to Sedna. A direct flight and flights including gravity assist manoeuvres are considered. The present study showed that a direct flight would be practically unrealistic due to the high total characteristic velocity and the time of flight value. Promising scenarios include gravity assist manoeuvres near Venus, Earth, Jupiter, Saturn and Neptune. The analysis of the close approach to asteroids during the flight to Sedna had been performed. Results of the research presented in this article show that the launch in 2029 provides the best transfer conditions in terms of minimum total characteristic velocity. The analysis shows that with a small additional impulses flybys of the large main-belt asteroids (16) Psyche for launch in 2034 and (20) Massalia for launch in 2029 are possible.
Non-linear Study of Bell's Cosmic Ray Current-driven Instability
Creators: name: Riquelme, Mario A.
name: Spitkovsky, Anatoly
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The cosmic ray current-driven (CRCD) instability, predicted by Bell (2004), consists of non-resonant, growing plasma waves driven by the electric current of cosmic rays (CRs) that stream along the magnetic field ahead of both relativistic and non-relativistic shocks. Combining an analytic, kinetic model with one-, two-, and three-dimensional particle-in-cell simulations, we confirm the existence of this instability in the kinetic regime and determine its saturation mechanisms. In the linear regime, we show that, if the background plasma is well magnetized, the CRCD waves grow exponentially at the rates and wavelengths predicted by the analytic dispersion relation. The magnetization condition implies that the growth rate of the instability is much smaller than the ion cyclotron frequency. As the instability becomes non-linear, significant turbulence forms in the plasma. This turbulence reduces the growth rate of the field and damps the shortest wavelength modes, making the dominant wavelength, λ_d, grow proportional to the square of the field. At constant CR current, we find that plasma acceleration along the motion of CRs saturates the instability at the magnetic field level such that v_A ~ v_{d,cr}, where v_A is the Alfven velocity in the amplified field, and v_{d,cr} is the drift velocity of CRs. The instability can also saturate earlier if CRs get strongly deflected by the amplified field, which happens when their Larmor radii get close to λ_d. We apply these results to the case of CRs in the upstream medium of supernova remnants. Considering only the most energetic CRs that escape from the shock, we obtain that the field amplification factor of ~10 can be reached. This confirms the CRCD instability as a potentially important component of magnetic amplification process in astrophysical shocks.

description: Current research focuses on designing fast trajectories to the trans-Neptunian object (TNO) (90377) Sedna to study the surface and composition from a close range. Studying Sedna from a close distance can provide unique data about the Solar System evolution process including protoplanetary disc and related mechanisms. The trajectories to Sedna are determined considering flight time and the total characteristic velocity ($ΔV$) constraints. The time of flight for the analysis was limited to 20 years. The direct flight, the use of gravity assist manoeuvres near Venus, the Earth and the giant planets Jupiter and Neptune, and the flight with the Oberth manoeuvre near the Sun are considered. It is demonstrated that the use of flight scheme with $ΔVEGA$ ($ΔV$ and Earth Gravity Assist manoeuvre) and Jupiter-Neptune gravity assist leads to the lowest cost of $ΔV$=6.13 km/s for launch in 2041. The maximum payload for schemes with $Δ$VEGA manoeuvre is 500 kg using Soyuz 2.1.b, 2,000 kg using Proton-M and Delta IV Heavy and exceeds $12,000$ kg using SLS. For schemes with only Jupiter gravity assist, payload mass is twice less than for ones with $Δ$VEGA manoeuvre. As a possible expansion of the mission to Sedna, it is proposed to send a small spacecraft to another TNO during the primary flight to Sedna. Five TNOs suitable for this scenario are found, three extreme TNOs 2012 VP113, (541132) Leleākūhonua (former 2015 TG387), 2013 SY99) and two classical Kuiper Belt objects: (90482) Orcus, (20000) Varuna.

description: The extension of the Standard Model (SM) with two Higgs triplets offers an appealing way to account for both tiny Majorana neutrino masses via the type-II seesaw mechanism and the cosmological matter-antimatter asymmetry via the triplet leptogenesis. In this paper, we classify all possible accidental symmetries in the scalar potential of the two-Higgs-triplet model (2HTM). Based on the bilinear-field formalism, we show that the maximal symmetry group of the 2HTM potential is ${\rm SO(4)}$ and eight types of accidental symmetries in total can be identified. Furthermore, we examine the impact of the couplings between the SM Higgs doublet and the Higgs triplets on the accidental symmetries. The bounded-from-below conditions on the scalar potential with specific accidental symmetries are also derived. Taking the ${\rm SO(4)}$-invariant scalar potential as an example, we investigate the vacuum structures and the scalar mass spectra of the 2HTM.

A pérola foi a pioneira das gemas na Antiguidade, uma preciosidade escondida sob uma capa - a concha, que requer esforço e cuidado para ser adquirida, o mesmo que é exigido para alcançar a Verdade ou o Conhecimento. Iremos argumentar no sentido da definição deste poema como, simultaneamente, uma alegoria e uma elegia. Adicionalmente, considerámos relevante estabelecer uma analogia com o significado e proeminência noutras obras e, por fim, concluiremos se existe ou não uma metamorfose do simbolismo ao longo dos tempos, assim como as disparidades e semelhanças em diferentes formas de representação desta gema.

Participation in continuing education by employed dental hygienists in British Columbia

description: The study reported on the participation patterns of dental hygienists in the Province of British Columbia during the period of March 1971 to March 1974. The study surveyed 163 dental hygienists registered and licenced with the College of Dental Surgeons of British Columbia in 1973 who were resident and employed in the Province at the time of the study. These 163 hygienists represented 76.2 per cent of dental hygienists registered and licenced in British Columbia in 1973. Eleven variables were selected for study: age, marital status, number of children, years of post-secondary education, year and place of graduation, place of residence, work towards further dental or non-dental qualifications, employment status and principal type of employment. Of these variables only three were found to differentiate between participants and non-participants which were: place of graduation, work towards non-dental qualifications and principal type of employment. The courses attended were grouped into four categories: clinical skills, patient evaluation, dental health education and practice management. The eleven variables were tested against the four course categories to determine whether any of the characteristics influenced participation in the different types of courses. In four instances significant differences were found: age was related to attendance in clinical skills courses; the number of years of post-secondary education was related to participation in clinical skills courses and patient evaluation courses; and marital status was related to participation in practice management courses. The findings of this study indicate that the socio-economic variables considered had little influence on the participation patterns of dental hygienists and emphasizes the need for future research concerning the role of psychological and other factors influencing participation in continuing education programs.

When the resource state is Gaussian, our method makes the approach to the transfer of quantum correlations much more flexible than in previously considered schemes and allows the straightforward inclusion of the effects of noise affecting the CV system. Moreover, the proposed method reveals that the use of de-Gaussified two-mode states is almost never advantageous for transferring entanglement with respect to the full Gaussian picture, despite the entanglement in the non-Gaussian resource can be much larger than in its Gaussian counterpart. We can thus conclude that the entanglement-transfer map overthrows the "ordering" relations valid at the level of CV resource states.

Le strategie del camaleonte. Dispositivi mimetici nell'arte contemporanea

description: Inizialmente teorizzato a partire dall’osservazione degli animali negli studi di etologia di fine Ottocento, il mimetismo si è sviluppato come tekné in una interessante sinergia fra pratica artistica e necessità militare in occasione dei due conflitti mondiali. Attraverso una lettura critica dei testi di Roger Caillois e di Georges Bataille, questa ricerca posiziona il mimetismo nell’ambito della teoria della antivisione e lo inserisce all’interno del discorso anti-oculocentrico che scorre nei canali sotterranei dell’arte del Novecento. Il mimetismo destabilizza il dogma modernista della visualità pura operando un oltrepassamento dei confini identitari e il collasso della logica binaria dell’estetica occidentale fondata sulla opposizione fra soggetto e oggetto, interiorità ed esteriorità, corpo e ambiente. Articolato in tre diverse declinazioni del fare artistico - il paradigma spaziale, il paradigma aptico e il paradigma performativo – il mimetismo veicola un tipo di “presenza” che mette in gioco il corpo ed il contesto extracorporeo in un recupero estetico del valore fenomenologico dell’essere al mondo.

description: Fully understanding the average core-collapse supernova requires detecting the diffuse supernova neutrino background (DSNB) in all flavors. While the DSNB $\barν_e$ flux is near detection, and the DSNB $ν_e$ flux has a good upper limit and prospects for improvement, the DSNB $ν_x$ (each of $ν_μ, ν_τ, \barν_μ, \barν_τ$) flux has a poor limit and heretofore had no clear path for improved sensitivity. We show that a succession of xenon-based dark matter detectors -- XENON1T (completed), XENONnT/LUX-ZEPLIN (running), and DARWIN (proposed) -- can dramatically improve sensitivity to DSNB $ν_x$ the neutrino-nucleus coherent scattering channel. XENON1T could match the present sensitivity of $\sim 10^3 \; \mathrm{cm}^{-2}~\mathrm{s}^{-1}$ per $ν_x$ flavor, XENONnT/LUX-ZEPLIN would have linear improvement of sensitivity with exposure, and a long run of DARWIN could reach a flux sensitivity of $\sim 10 \; \mathrm{cm}^{-2}~\mathrm{s}^{-1}$. Together, these would also contribute to greatly improve bounds on non-standard scenarios. Ultimately, to reach the standard flux range of $\sim 1 \; \mathrm{cm}^{-2}~\mathrm{s}^{-1}$, even larger exposures will be needed, which we show may be possible with the series of proposed lead-based RES-NOVA detectors.

description: In this work, we demonstrate that cutting diamond crystals with a laser (532~nm wavelength, 0.5~mJ energy, 200~ns pulse duration at 15~kHz) produces a $\lesssim 20~$nm thick surface layer with magnetic order at room temperature. We have measured the magnetic moment of five natural and six CVD diamond crystals of different size, nitrogen content and surface orientations with a SQUID magnetometer. A robust ferromagnetic response at 300~K is observed only for crystals that were cut with the laser along the (100) surface orientation. The magnetic signals are much weaker for the (110) and negligible for the (111) orientations. We attribute the magnetic order to the disordered graphite layer produced by the laser at the diamond surface. The ferromagnetic signal vanished after chemical etching or after moderate temperature annealing. The obtained results indicate that laser treatment of diamond may pave the way to create ferromagnetic spots at its surface.

description: We report the discovery of a $M=67\pm2~\mathrm{M_J}$ brown dwarf transiting the early M dwarf TOI-2119 on an eccentric orbit ($e=0.3362 \pm 0.0005$) at an orbital period of $7.200861 \pm 0.000005$ days. We confirm the brown dwarf nature of the transiting companion using a combination of ground-based and space-based photometry and high-precision velocimetry from the Habitable-zone Planet Finder. Detection of the secondary eclipse with TESS photometry enables a precise determination of the eccentricity and reveals the brown dwarf has a brightness temperature of $2100\pm80$ K, a value which is consistent with an early L dwarf. TOI-2119 is one of the most eccentric known brown dwarfs with $P<10$ days, possibly due to the long circularization timescales for an object orbiting an M dwarf. We assess the prospects for determining the obliquity of the host star to probe formation scenarios and the possibility of additional companions in the system using Gaia EDR3 and our radial velocities.

description: The Universal Extra Dimensions model has been implemented in the Pythia generator from version 6.4.18 onwards, in its minimal formulation with one inverse-TeV-sized extra dimension. The additional possibility of gravity-mediated decays, through a variable number of inverse-eV-sized extra dimensions into which only gravity extends, is also available. The implementation covers the lowest-lying Kaluza-Klein (KK) excitations of Standard Model particles, except for the excitations of the Higgs fields, with the mass spectrum calculated at one loop. 2 -> 2 tree-level production cross sections and KK number conserving 2-body decays are included. Mixing between iso-doublet and -singlet KK excitations is neglected thus far, and is expected to be negligible for all but the top sector.

description: We report on the possibility for a spin valve effect driven by edge defect engineering of zigzag graphene nanoribbons. Based on a mean-field spin unrestricted Hubbard model, electronic band structures and conductance profiles are derived, using a self-consistent scheme to include gate-induced charge density. The use of an external gate is found to trigger a semiconductor-metal transition in clean zigzag graphene nanoribbons, whereas it yields a closure of the spin-split bandgap in the presence of Klein edge defects. These features could be exploited to make novel charge and spin based switches and field effect devices.

description: Magnetars are the most promising progenitors of Fast Radio Bursts (FRBs). Strong radio waves propagating through the magnetar wind are subject to non-linear effects, including modulation/filamentation instabilities. We derive the dispersion relation for modulations of strong waves propagating in magnetically-dominated pair plasmas focusing on dimensionless strength parameters $a_0\lesssim 1$, and discuss implications for FRBs. As an effect of the instability, the FRB radiation intensity develops sheets perpendicular to the direction of the wind magnetic field. When the FRB front expands outside the radius where the instability ends, the radiation sheets are scattered due to diffraction. The FRB scattering timescale depends on the properties of the magnetar wind. In a cold wind, the typical scattering timescale is $τ_{\rm sc}\sim{\rm\; μs-ms}$ at the frequency $ν\sim 1{\rm\; GHz}$. The scattering timescale increases at low frequencies, with the scaling $τ_{\rm sc}\proptoν^{-2}$. The frequency-dependent broadening of the brightest pulse of FRB 181112 is consistent with this scaling. From the scattering timescale of the pulse, one can estimate that the wind Lorentz factor is larger than a few tens. In a warm wind, the scattering timescale can approach $τ_{\rm sc}\sim{\rm\; ns}$. Then scattering produces a frequency modulation of the observed intensity with a large bandwidth, $Δν\sim 1/τ_{\rm sc}\gtrsim 100{\rm\; MHz}$. Broadband frequency modulations observed in FRBs could be due to scattering in a warm magnetar wind.

description: Project Raijin is an NSF EarthCube-funded effort whose goal is to develop community-owned tools that facilitate operating on unstructured climate and global weather data. We plan to: (1) develop extensible, scalable tools supporting fundamental analysis and visualization methods capable of operating directly (without resampling) on unstructured grid model outputs at global storm resolving resolutions; and (2) establish an active, vibrant community of user-contributors, committed to extending our work beyond the scope of this NSF award. The primary environment for Project Raijin is the Scientific Python Ecosystem. We will leverage, in particular, the open development Xarray and Dask packages, and the Pangeo community. This presentation will provide an overview of Project Raijin, and discuss how you can get involved.
