description: We define a quasiclassical limit of the Lian-Zuckerman homotopy BV algebra (quasiclassical LZ algebra) on the subcomplex, corresponding to "light modes", i.e. the elements of zero conformal weight, of the semi-infinite (BRST) cohomology complex of the Virasoro algebra associated with vertex operator algebra (VOA) with a formal parameter. We also construct a certain deformation of the BRST differential parametrized by a constant two-component tensor, such that it leads to the deformation of the $A_{\infty}$-subalgebra of the quasiclassical LZ algebra. Altogether this gives a functor the category of VOA with a formal parameter to the category of $A_{\infty}$-algebras. The associated generalized Maurer-Cartan equation gives the analogue of the Yang-Mills equation for a wide class of VOAs. Applying this construction to an example of VOA generated by $β$-$γ$ systems, we find a remarkable relation between the Courant algebroid and the homotopy algebra of the Yang-Mills theory.

description: Intracerebral hemorrhage (ICH) is a severe form of stroke characterized by high mortality and disability rates. Understanding the molecular and cellular mechanisms underlying ICH is critical for developing effective therapies. In this study, we utilized single-nucleus Assay for Transposase-Accessible Chromatin using sequencing (snATAC-seq) to explore the dynamics of chromatin accessibility within the first month post-ICH in mice. We analyzed 262,506 single cells, identifying 77,978 upregulated and 35,023 downregulated unique candidate cis-regulatory elements (cCREs) across specific time points post-ICH (days 1, 3, 7, 14, and 28). Our results uncover the dysregulation of multiple super-enhancers in microglia/macrophages and detail the transition of reactive astrocytes from a protective state to a neurotoxic profile. Moreover, we observed a marked upregulation of genes involved in hypoxia response and lipid metabolism within the remyelination pathways post-ICH. This study sheds light on the epigenetic alterations following ICH, providing a foundation for future research and potential therapeutic interventions.

description: The amniote pallium, a vital component of the forebrain, has undergone considerable evolutionary divergence across species and is critical for a variety of functions including sensation, memory and learning. The relationship between pallial subregions in different species remain elusive, particularly regarding the identification of homologous neurons and their similar or distinct signatures. Here, we utilized single-nucleus RNA sequencing to examine over 130,000 nuclei from macaque (Macaca fascicularis) neocortex, alongside datasets from human (Homo sapiens), mouse (Mus musculus), zebra finch(Taeniopygia guttata), turtle (Chrysemys picta bellii), and lizard (Pogona vitticeps), for a cross-species comparison.

description: Using Fe/GaAs Schottky tunnel barriers as electrical spin detectors, we show that the magnitude and sign of their spin-detection sensitivities can be widely tuned with the voltage bias applied across the Fe/GaAs interface. Experiments and theory establish that this tunability derives not just simply from the bias dependence of the tunneling conductances $G_{\uparrow,\downarrow}$ (a property of the interface), but also from the bias dependence of electric fields in the semiconductor which can dramatically enhance or suppress spin-detection sensitivities. Electrons in GaAs with fixed polarization can therefore be made to induce either positive or negative voltage changes at spin detectors, and some detector sensitivities can be enhanced over ten-fold compared to the usual case of zero-bias spin detection.

Long-term Evolution of the Short-term X-ray Variability of the Jetted TDE Swift J1644+57

description: The short-term X-ray variability of tidal disruption events (TDEs) and its similarities with active galactic nuclei (AGN) are poorly understood. In this work, we show the diversity of TDE's short-term X-ray variability, and take Swift J1644+57 as an example to study the evolution of various properties related to the short-term X-ray variability, such as the X-ray flux distribution, power spectral density (PSD), rms variability, time lag and coherence spectra. We find that the flux distribution of Swift J1644+57 has a lognormal form in the normal state, but deviates from it significantly in the dipping state, thereby implying different physical mechanisms in the two states. We also find that during the first two XMM-Newton observations in the dipping state, Swift J1644+57 exhibited different variability patterns, which are characterized by steeper PSDs and larger rms than the normal state. A significant soft X-ray lag is detected in these two observations, which is ~50 s between 0.3-1 keV and 2-10 keV with a high coherence. Using the 2-10 keV rms of 0.10-0.50, the black hole mass of Swift J1644+57 is estimated to be $(0.6-7.9)\times10^{6}M_{\odot}$, but the variation of rms as the TDE evolves introduces a large uncertainty. Finally, we discuss the value of conducting similar studies on other TDEs, especially in the coming era of time-domain astronomy when a lot more TDEs will be discovered in X-rays promptly. This also heralds a significant increase in the demand for deep follow-up observations of X-ray selected TDEs with X-ray telescopes of large effective areas and long orbital periods.

description: In this paper we analyse a setup where consumers are heterogeneous in the perception of environmental quality. The equilibrium is verified in a setting with horizontal and vertical (green) differentiation. Profits are increasing in the misperception of quality, while, the investment in green quality decreases the more the goods are substitutes. We further consider the introduction of either an emission tax or an environmental standard. The former rises the investment in environmental quality due to the higher cost of production, whereas in equilibrium quality always improves after the introduction of the latter. We show that an optimal environmental standard is an effective regulatory instrument against greenwashing and that the efficacy of the interventions is conditioned to the damage distribution and the aggregate level of emission.

description: We calculate potentials between a proton and a $Ξ^0$ (hyperon with strangeness -2) through the equal-time Bethe-Salpeter wave function, employing quenched lattice QCD simulations with the plaquette gauge action and the Wilson quark action on (4.5 fm)^4 lattice at the lattice spacing $a \simeq 0.14$ fm. The ud quark mass in our study corresponds to $m_π\simeq 0.37$ and 0.51 GeV, while the s quark mass corresponds to the physical value of $m_K$. The central $p Ξ^0$ potential has a strong (weak) repulsive core in the $^1S_0$ ($^3S_1$) channel for $r \lsim 0.6$ fm, while the potential has attractive well at the medium and long distances (0.6 fm $\lsim r \lsim 1.2$ fm) in both channels. The sign of the $p Ξ^0$ scattering length and its quark mass dependence indicate a net attraction in both channels at low energies.

Light Pseudoscalar Higgs boson in Neutralino Decays in the Next-to-Minimal Supersymmetric Standard Model

description: We point out another important production channel of a light pseudoscalar Higgs boson $a_1$ via the decays of neutralinos, including $\widetildeχ_{2,3}^0 \to \widetildeχ_{1}^0 a_1$, in the framework of the NMSSM. We scan the whole parameter space using the most up-to-date version of NMHDECAY and search for regions where $B(\widetildeχ_{2,3}^0 \to \widetildeχ_{1}^0 a_1) > 0.5$. If the gluino and squarks are light enough for copious production of SUSY events at the LHC, there would be numerous number of $\widetildeχ_{2,3}^0$ in subsequent decays of gluinos and squarks. Therefore, the production rates of $a_1$ via neutralino decays would be more important than $h \to a_1 a_1$ and others. Potentially, the final state is filled with many $τ$ leptons, which can be reconstructed at the mass of $a_1$. This is a clean, observable, and distinguishable signature for NMSSM.

MICHEL FOUCAULT'S DEATH SPACE

subject: Philosophy of specific cultures (incl. comparative philosophy)

description: The problem of death and immortality has always been one of the central themes in philosophy, it has many aspects and can be considered from different points of view. Most people desire to continue their existence after death, and this desire can be driven by various factors, such as fear of the unknown after life, the desire to preserve one's identity or achievements, and the belief in continued life in another world. Studying death and its impact on our lives helps us better understand ourselves and the world around us. A person is afraid of death and does not want to die, so death remains a mystery to him. M. Foucault also says that we need to understand how death affects daily life, our behavior and the way we communicate. Our attitude towards death determines our outlook on life, on values, and on what we consider important. M. Foucault, in turn, notes that in modern society, death has become a hidden and taboo topic that is not talked about openly. This is due to the fact that death has ceased to be a part of life, but has become something that should be excluded from it. In this regard, M. Foucault introduces the concept of heterotopias as places that do not correspond to the general rules and laws of the social order, but are a kind of «cutouts» in the social structure. These places are both remote and present in the public space at the same time. They represent a kind of «mirror» of social reality and at the same time differ from it. Contemporary space contains many heterotopias that reflect diverse practices and cultural meanings. He notes that in our time, death is taken out of the public space; people try to avoid death and discuss it, preferring to do more pleasant things.He notes that heterotopias are not static and closed spaces, but rather dynamic and changing places that are constantly being rethought and redefined in a social context. Beyond any doubt is the obvious fact that the concept of «body» is directly related to death. Despite the most diverse interpretations of death (religious, atheistic, mythological, materialistic or idealistic), they all agree on one point – death is the cessation of the life of the organism, that is, it is the end of the human body.
Numerical Simulations of a Protostellar Outflow Colliding with a Dense Molecular Cloud

description: High-resolution SiO observations of the NGC 1333 IRAS 4A star-forming region showed a highly collimated outflow with a substantial deflection. The deflection was suggested to be caused by the interactions of the outflow and a dense cloud core. To investigate the deflection process of protostellar outflows, we have carried out three-dimensional hydrodynamic simulations of the collision of an outflow with a dense cloud. Assuming a power-law type density distribution of the obstructing cloud, the numerical experiments show that the deflection angle is mainly determined by the impact parameter and the density contrast between the outflow and the cloud. The deflection angle is, however, relatively insensitive to the velocity of the outflow. Using a numerical model with physical conditions that are particularly suitable for the IRAS 4A system, we produce a column-density image and a position-velocity diagram along the outflow, and they are consistent with the observations. Based on our numerical simulations, if we assume that the initial density and the velocity of the outflow are $\sim 10 \cm3$ and $\sim 100 \kms$, the densities of the dense core and ambient medium in the IRAS 4A system are most likely to be $\sim 10^5 \cm3$ and $\sim 10^2 \cm3$, respectively. We therefore demonstrate through numerical simulations that the directional variability of the IRAS 4A outflow can be explained reasonably well using the collision model.

description: We present the ALMA view of 11 main-sequence DSFGs, (sub-)millimeter selected in the GOODS-S field, and spectroscopically confirmed to be at the peak of Cosmic SFH (z = 2-3). Our study combines the analysis of galaxy SED with ALMA continuum and CO spectral emission, by using ALMA Science Archive products at the highest spatial resolution currently available for our sample (< 1 arcsec). We include galaxy multi-band images and photometry (in the optical, radio and X-rays) to investigate the interlink between dusty, gaseous and stellar components and the eventual presence of AGN. We use multi-band sizes and morphologies to gain an insight on the processes that lead galaxy evolution, e.g. gas condensation, star formation, AGN feedback. The 11 DSFGs are very compact in the (sub-)millimeter (median r(ALMA) = 1.15 kpc), while the optical emission extends tolarger radii (median r(H)/r(ALMA) = 2.05). CO lines reveal the presence of a rotating disc of molecular gas, but we can not exclude either the presence of interactions and/or molecular outflows. Images at higher (spectral and spatial) resolution are needed to disentangle from the possible scenarios. Most of the galaxies are caught in the compaction phase, when gas cools and falls into galaxy centre, fuelling the dusty burst of star formation and the growing nucleus. We expect these DSFGs to be the high-zstar-forming counterparts of massive quiescent galaxies. Some features of CO emission in three galaxies are suggestive of forthcoming/ongoing AGN feedback, that is thought to trigger the morphological transition from star-forming disks to ETGs.

Prospect of Flood-Friendly Housing in Sunderbans: Future Directions

Year: 2023
Subjects: Flood-friendly housing, Sunderbans, climate change, resilience

description: Sunderbans is located in the delta region of Bay of Bengal, which is a vulnerable area to the impacts of climate change; particularly flooding. Increasing frequency and intensity of floods have resulted in massive loss of lives and properties and severely affected the socio-economic well-being of the local population.  In this research, flood-friendly housing is presented as a promising solution to mitigate the impact of floods. The literature review aims to explore the prospects of flood-friendly housing, and identify future directions for research and action. It highlights that flood- resilient housing technologies have evolved significantly in recent years and several prototypes have been developed and tested. However, implementation of flood-friendly housing remains scanty due to lack of financial, institutional support, technical expertise, and community participation. The research also identifies the gaps in literature related to the socio-cultural, economic, and environmental dimensions of flood-friendly housing in Sunderbans. Future directions suggested in this review include developing innovative financing schemes, promoting community participation, integrating local knowledge and practices, and assessing long-term sustainability of flood-friendly housing in the target area. Further, it establishes that flood-friendly housing has huge potential to provide viable solution to the challenges of flooding, if implemented through ‘multi-stakeholder and participatory’ approach, for which Indian context is appropriate.

description: In several searches for additional Higgs bosons at the LHC, in particular in a CMS search exploring decays to pairs of top quarks, $t \bar t$, and in an ATLAS search studying tau leptons, $\tau^+\tau^-$, local excesses of about $3\,\sigma$ standard deviations or above have been observed at a mass scale of approximately $ 400$GeV. We investigate to what extent a possible signal in these channels could be accommodated in the Next-to-Two-Higgs-Doublet Model (N2HDM) or the Next-to Minimal Supersymmetric Standard Model (NMSSM). In a second step we analyze whether such a model could be compatible with both a signal at around $400$GeV and $96$GeV, where the latter possibility is motivated by observed excesses in searches for the $b \bar b$ final state at LEP and the di-photon final state at CMS. The analysis for the N2HDM reveals that the observed excesses at $400GeV$ in the $t \bar t$ and $\tau^+\tau^-$ channels point towards different regions of the parameter space, while one such excess and an additional Higgs boson at around $96$GeV could simultaneously be accommodated. In the context of the NMSSM an experimental confirmation of a signal in the $t \bar t$ final state would favour the alignment-without-decoupling limit of the model, where the Higgs boson at $125$GeV could be essentially indistinguishable from the Higgs boson of the standard model. In contrast, a signal in the $\tau^+\tau^-$ channel can only be accommodated outside of this limit, and parts of the investigated parameter space could be probed with Higgs signal-rate measurements at the (HL-)LHC.
Geometrical and Physical Properties of Circumbinary Discs in Eccentric Stellar Binaries

description: In a previous work (Pichardo et al. 2005), we studied stable configurations for circumstellar discs in eccentric binary systems. We searched for "invariant loops": closed curves (analogous to stable periodic orbits in time-independent potentials) that change shape with the binary orbital phase, as test particles in them move under the influence of the binary potential. This approach allows us to identify stable configurations when pressure forces are unimportant, and dissipation acts only to prevent gas clouds from colliding with one another. We now extend this work to study the main geometrical properties of circumbinary discs. We have studied more than 100 cases with a range in eccentricity 0 .le. e .le. 0.9, and mass ratio 0.1 .le. q .le. 0.9. Although gas dynamics may impose further restrictions, our study sets lower stable bounds for the size of the central hole in a simple and computationally cheap way, with a relation that depends on the eccentricity and mass ratio of the central binary. We extend our previous studies and focus on an important component of these systems: circumbinary discs. The radii for stable orbits that can host gas in circumbinary discs are sharply constrained as a function of the binary's eccentricity. The circumbinary disc configurations are almost circular, with eccentricity e_d < 0.15, but if the mass ratio is unequal the disk is offset from the center of mass of the system. We compare our results with other models, and with observations of specific systems like GG Tauri A, UY Aurigae, HD 98800 B, and Fomalhaut, restricting the plausible parameters for the binary.

Scale-free patterns at a saddle-node bifurcation in a stochastic system

description: We demonstrate that scale-free patterns are observed in a spatially extended stochastic system whose deterministic part undergoes a saddle-node bifurcation. Remarkably, the scale-free patterns appear only at a particular time in relaxation processes from a spatially homogeneous initial condition. We characterize the scale-free nature in terms of the spatial configuration of the exiting time from a marginal saddle where the pair annihilation of a saddle and a node occurs at the bifurcation point. Critical exponents associated with the scale-free patterns are determined by numerical experiments.

description: We survey the cohomology jumping loci and the Alexander-type invariants associated to a space, or to its fundamental group. Though most of the material is expository, we provide new examples and applications, which in turn raise several questions and conjectures. The jump loci of a space X come in two basic flavors: the characteristic varieties, or, the support loci for homology with coefficients in rank 1 local systems, and the resonance varieties, or, the support loci for the homology of the cochain complexes arising from multiplication by degree 1 classes in the cohomology ring of X. The geometry of these varieties is intimately related to the formality, (quasi-) projectivity, and homological finiteness properties of π_1(X). We illustrate this approach with various applications to the study of hyperplane arrangements, Milnor fibrations, 3-manifolds, and right-angled Artin groups.

It includes "in-parcel" trees and trees on parcel boundaries (e.g. lines of trees and hedges).  Small groups of trees are counted as agroforestry provided that they are smaller or thinner than the size or width definitions used by Member States for "forest", as defined in Annex II of the LULUCF Regulation (see EURAF Policy Briefings #17 and #15). Agroforestry also includes woody landscape features,  as defined in CAP legislation (Policy Briefing #21) and in the Nature Restoration Regulation (Policy Briefing #18).  These landscape features are recorded in the Land Parcel Identification Systems (LPIS) of almost all Member States, and are reported as CAP Impact Indicator 21.

This presentation was made at a joint Refrescar and CAP Network event in the Cork Oak and Cork Competence Centre, Coruche, Portugal, 25.9.24.  It focused on agroforestry policies in Belgium-Flanders, Czechia, Germany, Greece, Spain, Italy, Poland, Portugal, Slovakia.  These are the only nine EU Member States with specific CAP agroforestry measures. Other countries (e.g. Ireland and France) support agroforestry from national budgets ourside the CAP.  These follow conditions in the Agricultural Block Exemption Reguliation (see EURAF Policy Briefing #19).  Agroforestry has been supported in the CAP since 2007 (see Policy Briefing #11), but its uptake is still very limited. In the CAP 2014-2022 around 80k ha were planned by Member States, but only 5k ha has been established.   Reasons include:  a) late or only partial advertising of agroforestry schemes by managing authorities; b) farmers having limited information and few concrete examples, c) low establishment and maintenance rates; d) annual support given for fewer years than conventional afforestation; e) high levels of bureaucracy, with many limitations over eligible costs, tree species eligibility and whether shrub species can be used;  f) difficulties combining ("stacking") with other grants (e.g. organic farming); g) problems entering tree rows into the geospatial aid application systems - since farmers are not allowed to do this themselves;  h) managing authorities lack knowledge of agroforestry and perceive a high administrative burden; i) farmers are uncertain of their future eligibility for direct payments; j) management contracts are not available to allocate costs and benefits between owners and tenant-farmers; k) auditors don´t fully understand the  "pro-rata reduction rules" in silvopastoral area payments, and have fined countries in the past (e.g. Greece, Latvia) for perceived over-payments.

description: The detection of pairs of sleptons, charginos and charged higgs bosons produced via photon-photon fusion at the LHC is studied, assuming a couple of benchmark points of the MSSM model. Due to low cross sections, it requires large integrated luminosity, but thanks to the striking signature of these exclusive processes the backgrounds are low, and are well known. Very forward proton detectors can be used to measure the photon energies, allowing for direct determination of masses of the lightest SUSY particle, of selectrons and smuons with a few GeV resolution. Finally, the detection and mass measurement of quasi-stable particles predicted by the so-called sweet spot supersymmetry is discussed.

description: Growing evidence indicate supermassive black holes (SMBHs) in a mass range of $M_{\rm BH}$$\sim 106-10^{10}M_{\odot}$ lurking in central stellar bulges of galaxies.Extensive observations reveal fairly tight power laws of $M_{\rm BH}$ versus the mean stellar velocity dispersion $σ$ of the host stellar bulge.Together with evidence for correlations between $M_{\rm BH}$ and other properties of host bulges, the dynamic evolution of a bulge and the formation of a central SMBH should be linked. In this Letter, we reproduce the empirical $M_{\rm BH}-σ$ power laws based on our recent theoretical analyses (Lou & Wang; Wang & Lou; Lou, Jiang & Jin) for a self-similar general polytropic quasi-static dynamic evolution of bulges with self-gravity and spherical symmetry and present a sensible criterion of forming a central SMBH. The key result is $M_{\rm BH}={\cal L}σ^{1/(1-n)}$ where $2/3

description: A detailed computational study was performed to investigate the conformational changes of flap region and the mechanism underlying the binding of the inhibitor TMC-126 to HIV-1 protease (PR1) and its mutant variants through molecular dynamics simulations in conjunction with the molecular mechanics Poisson–Boltzmann (MM-PBSA) free energy calculation. Further, we have studied the effectiveness of the inhibitor against HIV-2 protease (PR2). The MM-PBSA calculation suggests that TMC-126 loses its potency against mutant variants and PR2 compared to wild-type PR1 mainly due to the loss in intermolecular electrostatic interactions. The potency of the inhibitor decreases in the order: wild type PR1 > M46L > MDR20 > I50V > PR2 > V32I > A28S. Our study reveals that the flap of PR1 adopts a semi-open conformation due to the mutation I50V or MDR20. The dissimilar nature of the movement of the flap tip of both monomers is evident from the dynamic cross-correlation map. The protein structural network analysis displays that mutation causes structural rearrangements and changes the communication path between residues. Overall, we believe our study may help explore and accelerate the development of novel HIV-1/HIV-2 protease inhibitors with better potency.

description: Phosphodiesterase 5 (PDE5) falls under a broad category of metallohydrolase enzymes responsible for the catalysis of the phosphodiesterase bond, and thus it can terminate the action of cyclic guanosine monophosphate (cGMP). Overexpression of this enzyme leads to development of a number of pathological conditions. Thus, targeting the enzyme to develop inhibitors could be useful for the treatment of erectile dysfunction as well as pulmonary hypertension. In the current study, several molecular modelling techniques were utilized including Bayesian classification, single tree and forest tree recursive partitioning, and genetic function approximation to identify crucial structural fingerprints important for optimization of tri-substituted pyrazoline derivatives as PDE5 inhibitors. Later, various machine learning models were also developed that could be utilized to predict and screen PDE5 inhibitors in the future.

description: We calculate the leading order diphoton generalized distribution amplitude by calculating the amplitude of the process gamma* gamma -> gamma gamma in the low energy and high photon virtuality region at the Born order and in the leading logarithmic approximation. As in the case of the anomalous photon structure functions, the gamma gamma generalized distribution amplitude exhibits a characteristic \ln Q^2 behaviour and obeys inhomogeneous evolution equations.

description: HIV-1 protease (PR) is thought to be efficient targets of anti-AIDS drug design. Molecular dynamics (MD) simulations and multiple post-processing analysis technologies were applied to decipher molecular mechanism underlying binding of three drugs Lopinavir (LPV), Nelfinavir (NFV) and Atazanavir (ATV) to the PR. Binding free energies calculated by molecular mechanics generalized Born surface area (MM-GBSA) suggest that compensation between binding enthalpy and entropy plays a vital role in binding of drugs to PR. Dynamics analyses show that binding of LPV, NFV and ATV highly affects structural flexibility, motion modes and dynamics behaviour of the PR, especially for two flaps. Computational alanine scanning and interaction network analysis verify that although three drugs have structural difference, they share similar binding modes to the PR and common interaction clusters with the PR. The current findings also confirm that residues located interaction clusters, such as Asp25/Asp25ʹ, Gly27/Gly27ʹ, Ala28/Ala28ʹ, Asp29, Ile47/Ile47ʹ, Gly49/Gly49ʹ, Ile50/Ile50ʹ, Val82/Val82ʹ and Ile84/Ile84, can be used as efficient targets of clinically available inhibitors towards the PR.

description: This thesis investigates strategies to overcome the limitations of Neural Audio Synthesis (NAS) approaches in procedural audio, with a particular focus on enhancing conditional synthesis techniques. Contrary to previous assertions regarding limited control over meaningful conditioning parameters in neural approaches, we show that codec-based audio language modeling is a promising approach for procedural audio, both for its conditioning possibilities and the high quality of the sounds it produces. We concentrate on "environmental sounds", an underexplored area in neural audio synthesis, utilizing five distinct datasets of contact and texture sounds. The methodology employs the Improved RVQGAN neural audio compression codec (Descript Audio Codec) to compress audio waveforms into hierarchical sequences of discrete latent representations, thereby enabling the use of autoregressive Transformer models for sequence modeling. A total of 64 autoregressive decoder-only Transformer neural network were trained using three different conditioning strategies, as well as unconditional synthesis. Finally, we report a comprehensive quantitative and qualitative analysis of these models.

Parents’ beliefs, attitudes, and values and their relationship to the home environments provided for developmentally delayed infants involved in a home-based intervention program

description: The home environment has been shown to be of critical importance for optimal child development, particularly for infants demonstrating developmental delays with or without organic cause. Successful intervention programs for these children have been linked to parent involvement and to concomitant changes in the home environment. Little research, however, has concerned itself with parental beliefs, attitudes and values which may be reflected in the kinds of home environments provided for these delayed children. The present study, therefore, provides an initial investigation into several of these parental factors as they relate to the child's early environment. Fifty-nine families involved in a home-based intervention program for developmentally delayed infants were visited. Home environments were assessed by means of the HOME, a statistically reliable scale developed by Bettye Caldwell (1972) to measure important aspects of the quantity and quality of social, emotional, and cognitive support available to the young child within the home. Parents of these families were asked to complete a questionnaire containing various belief, attitude, and value scales. Parental beliefs, attitudes and values were found to significantly relate to the kinds of home environments experienced by the developmentally delayed infants in the Program sample. In general, parents providing the most optimal home environments were those who believed in their ability to influence their children's development, felt a personal sense of responsibility towards that development, accepted their children for who they were and felt warmly towards them, and who endorsed such relational values as family security and loving. Results were more striking for mothers than for fathers, perhaps due in part to their greater involvement with Program staff and activities. Further research is needed in order to clarify the complex relationship observed between Program impact and these various parental beliefs, attitudes, and values.
