Acute Toxicity of Chlorpyrifos on Histological Alterations in the Anomuran Crab, Emerita asiatica (H. Milne Edwards, 1837)

Acute toxicity of Chlorpyrifos on histological alterations in the different organs like gills, hepatopancreas and ovary of anomuran crab, Emerita asiatica was studied. Though Emerita asiatica is not a commercially viable crab, but it plays a vital role in the environment to maintain a stable marine ecosystem. Several steps and precautions measures should be taken to conserve these members of the marine food chain to have a stable ecosystem and also to protect this species from extinction. Thus, it can be concluded that the use of Chlorpyrifos which has been legally banned in India is justified. It has been proved by several workers and has been conformed in present investigation that use of this Chlorpyrifos causes serious damage to the vital organ of sand crabs gill, hepatopancreas and ovary. The application of Chlorpyrifos could be reduced in the agricultural field to nearby coastal regions.
Can a New Organization Mitigate Conflicts Among Multiple Institutions Managing a World Heritage Site?

This paper examines whether and to what extent a newly established public organization can facilitate coordination among existing organizations in a world heritage site by focusing on the Borobudur Tourism Authority Board (BOB). It was established in 2017 by the Indonesian government to reduce conflicts among the multiple organizations managing Borobudur World Heritage Site and to provide one-stop services in the area. The paper investigates how effective this newly created organization has been in achieving these goals by utilizing in-depth interviews of public officials and a survey of tourism service providers in the Borobudur area. Major findings include: (1) business conditions as perceived by service providers somewhat improved after the establishment of BOB; (2) however, existing authorities managing the Borobudur area bypass BOB as a coordinator; and (3) a result, conflicts among organizations involved in the Borobudur area remain.
Axial stretching and vortex definition

Four existing invariant criteria for defining a vortex are diagnosed analytically and demonstrated by the Burgers and Sullivan vortices. Two of the criteria are found disqualified as generally applicable, and one underestimates the core radius. The diagnosis leads to a general requirement for any possible criterion: it should be able to identify the vortex axis and allow for arbitrary axial strain.
Articulatory trade‐offs reduce acoustic variability in American English /r/ productions

Acoustic and articulatory recordings indicate that speakers utilize trade‐offs between different articulatory parameters to maintain acoustic stability during American English /r/ productions. Electromagnetic midsagittal articulometer data from seven subjects producing /r/ in five phonetic contexts were analyzed. Articulator configurations for /r/ in different contexts showed systematic trade‐offs between constriction length, constriction area, and front cavity volume. The hypothesized effects of these three parameters on F3, derived from acoustic theory, were verified using a 51‐tube model of the vocal tract derived from structural MRI scans of a speaker producing /r/. All seven subjects utilized a trade‐off between front cavity volume and the length of the constriction formed by the tongue. Further analysis of acoustic and articulatory variabilities indicates that the net effect of these articulatory covariances is a considerable reduction in acoustic variability, thus allowing large contextual variatio.
Offset magnetic dipoles in white dwarfs

Various authors have reported observations of the flux and circular polarization for the four stars KPD 0253 + 5052, PG 1658 + 441, PG 1533 - 057 and K 813 - 14. On the basis of the observational data, the stars were classified as magnetic white dwarfs. To place constraints on the magnetic field strengths and geometries of these stars, the relevant authors qualitatively compared the data with available theory and, in two cases, used a model of optically thin hydrogen threaded by a magnetic field. In this paper, a more detailed model for magnetic white dwarfs is used to assess the results previously obtained for these four stars. For one star (KPD 0253 + 5052), clear evidence is found for deviation from a centered dipole field structure. The observational data for the other stars are not uniquely explained by centered dipole models. The observations can be interpreted, however, through the additional use of dipole field geometries offset from the stellar center. 15 refs.
Satisfaction to Stay, Regret to Switch: Understanding Post-adoption Regret in Choosing Competing Technologies When Herding

Facing hundreds of similar alternatives in any technology adoption decision, users commonly take a shortcut in the decision making: following others in the herd! Although herding is found to be an influential force for technology adoption, this research sheds light on its distal on user staying power in post-adoption evaluations. Supplementing the dominant perspective that users will stay with the chosen technology when satisfactory with the technology performance, this research proposes a new regret perspective to account for users’ concerns about the competing technologies and the decision process in the technology adoption decision. A research model is accordingly constructed and tested in two longitudinal field studies on user adoption and post-adoption evaluations across competing technologies in both forms of free software and paid hardware, with samples collected in Asia and Europe. Based on the findings and insights, this research suggests to IT vendors on how to retain users in the new era with competing technologies by understanding how post-adoption regret, the predominant factor of user switching, is formed and how it can be lessened.

“I Hope That the People Caring for Me Know About Me”: Exploring Person-Centred Care and the Quality of Dementia Care

Background Person-centred care is at the core of high-quality dementia care but people living with dementia are often excluded from quality improvement efforts. We sought to explore person-centred care and quality of care from the perspectives of persons living with dementia in the community and their care partners. Methods We used a qualitative descriptive approach with in-person, semi-structured interviews with 17 participants (9 persons living with dementia and 8 care partners) from Ontario, Canada. Results Participants report that person-centred care is essential to the quality of dementia care. Three themes were identified that describe connections between person-centred care and quality of care: 1) “I hope that the people looking after me know about me”, 2) “I just like to understand [what’s happening] as we go down the road”, and 3) “But the doctor doesn’t even know all the resources that are available. ” Participants perceived that quality indicators over-emphasized technical/medical aspects of care and do not entirely capture quality of care. Conclusions Persons living with dementia and their care partners provide important insights into person-centredness and quality of care. Their perspectives on “quality” may differ from clinicians and researchers. Research is needed to better integrate their perspectives in quality improvement and person-centred care.
Splitting rules for the electronic spectra of two-dimensional Fibonacci-class quasicrystals with one kind of atom and two bond lengths

On the basis of the substitution rules for a one-dimensional Fibonacci-class chain, we construct two-dimensional Fibonacci-class quasierystals with one kind of atom and two bond lengths. In the framework of the single-electron tight-binding nearest-interaction transfer model, we study the splitting rules of the electronic energy spectra for two-dimensional Fibonacci-class quasicrystals by means of a decomposition-decimation method based on a renormalization-group technique, and we also calculate the electronic energy spectra numerically. It is found that there exist only three kinds of clusters-n×n, n×(n+1), and (n+1)×(n +1)-for all classes of two-dimensional quasilattices, and that the electronic energy bands split as Y m - n - f . The general formula of the number for energy levels is obtained. We discover that there is a kind of so-called Fibonacci-class-number set for the parameters used to describe the energy-level number, and we obtain the set formulas. The experienced formula are sought out. The analytical results are confirmed by numerical simulations.
Let’s All Go to the Movies, Together: A Social Cognitive Perspective on Diversity, Equity, and Inclusion in Management Education Video Clips

While video clips have undoubtedly advanced the practice of management education, social cognitive theory suggests that new sources of video clips may augment ongoing diversity, equity, and inclusion (DE&I) efforts in management classrooms and organizations. In this article, we begin by reviewing social cognitive theory research that points to links between video clips and DE&I outcomes that are part of many management classes and training curricula. Based on this social cognitive theory perspective, we discuss how management educators might foster learning and inclusion in management classrooms and organizations by incorporating video clips with a greater variety of demographic populations in managerial and organizationally impactful roles. To this end, we also provide a list of video resources that can be used to refresh or supplement the resources currently being used in undergraduate, graduate, online (synchronous and asynchronous), executive education, and corporate training courses that may present more homogeneous casts.

The ‘inner-horizon thermodynamics’ of Kerr black holes

For Kerr black holes, it is argued that the thermodynamics of the event horizons and of the inner horizons are described in a unified manner by using a dimensionless parameter h. It is defined by h=a/r H ≡h + on the event horizons and varies in the range of 0≤h≤1, while it is also given by h=r H /a=a/r − ≡h − on the inner horizons in the range of 1≤h≤∞, where a=J/Mc is the angular momentum radius and r H ≡r + , r − are the radii of the outer and inner horizons respectively. Every thermodynamic variable, other than the mass M and the angular momentum J, is also defined on both the outer and inner horizons, and its values form a pair of the roots of a quadratic equation with M and J contained in the coefficients, similar to the horizon radii r ± and h ±
The Experiences of Children with Exceptionalities in Two Mainstream Primary Schools in Postcolonial Guyana

This paper is an outcome from the investigation into the learning and socializing experiences and opportunities of children with Special Education Needs and/or Disabilities (SEN/D) in the two mainstream primary schools in Guyana. This study was conducted using an ethnographic approach over two semesters in 2018 employing participant observation and unstructured interviews. The data gathered was analyzed using situational analysis as posited by Adele Clarke. It revealed that children with exceptionalities also find the two mainstream schools challenging while dealing with marginalization, discrimination and stay in your lane directives differently than their peers who were perceived as unteachable and unwanted in mainstream schools. The data reveals the innovativeness and resilience of the children with exceptionalities as they navigate the barriers, they face in the two mainstream schools. Finally, I reveal through the data the power interplay among the individual children with exceptionalities, children without SEN/D and their mainstream teachers.
Molecular gas at high galactic latitudes

The present quantitative results of a CO survey of high latitude molecular gas shows 57 clouds in 35 complexes at absolute values of b not smaller than 25 deg. Maps of 33 clouds are presented, together with C-13O and CO(J = 2-1) observations. The clouds, 70 percent of which are associated with optical emission, are noted to be distributed asymmetrically with respect to b = 0 deg; this is consistent with a displacement of the sun of 30 pc above the midplane. Since the mean distance to the clouds is about 100 pc, they are the nearest clouds to the sun and may contain the nearest regions of star formation. 51 references.
An extension of a result of Liapounoff on the range of a vector measure

Liapounoff2 established in 1940 that the range of a countably additive finite measure with values in a finite-dimensional real vector space is bounded and closed and in the nonatomic case convex. A simplified proof of this result was given by Halmos' in 1948. The aim of the present paper is to extend this result to the following case. Let pit, 1 0 there exist a a>0 such that g*(E) <e for all ECS so that v*(E) <8. {Ei}, i= 1, 2, . , k, is said to be a decomposition of F if the Es are pairwise disjoint measurable subsets of X and UiEi= F. Let pit,
LA INTELIGENCIA EMOCIONAL Y EL SISTEMA DE CREENCIAS EN EL APRENDIZAJE DE LA MATEMÁTICA

La escuela debe constituir un espacio de participación e integración donde las emociones ocupen un lugar significativo y su influencia facilite la efectividad de cualquier actividad; sin embargo, al estudiar matemática los estudiantes experimentan emociones positivas o negativas originadas por docentes y compañeros. La investigación identificó los niveles de inteligencia emocional que poseen los estudiantes de bachillerato y su sistema de creencias en el aprendizaje de la matemática. Se asumió una metodología cuantitativa, sustentada en una investigación de campo de carácter descriptivo. La muestra estuvo conformada por 157 estudiantes de Primer Año BGU de la Unidad Educativa Santo Tomás Apóstol. Un porcentaje considerable de estudiantes mostró debilidades en cuanto a su inteligencia emocional percibida, y, por lo tanto, insuficiente dominio de sus habilidades emocionales, por lo que deben mejorar su atención, claridad y reparación emocional. Asimismo, en relación con el sistema de creencias se considera urgente un cambio en el accionar docente, para fomentar en los estudiantes el gusto por la matemática a través de nuevas metodologías que atiendan los componentes emocional, social y cognitivo de su quehacer diario.
The Far-Ultraviolet Spectrum of Z Camelopardalis in Quiescence and Standstill

We have obtained FUSE (905-1187 Å) spectra of the nonmagnetic cataclysmic variable Z Cam during a period of quiescence. The spectrum resembles that of a hot (57,000 K) metal-enriched white dwarf. A high effective temperature is consistent with the expectation that dwarf nova systems that show standstills, as Z Cam does, have higher than normal time-averaged mass accretion rates. It is also consistent with current estimates for the mass and distance to Z Cam. A white dwarf model in which 29% of the surface has a temperature of 72,000 K and the rest of the surface is at 26,000 K also reproduces the spectral shape and the continuum flux level at the nominal distance and white dwarf mass, and is a somewhat better statistical fit to the data. A second component could be due to a rotating accretion belt, a remnant of an outburst that ended 11 days prior to the FUSE observation, or ongoing accretion. We favor the uniform-temperature model for Z Cam, largely because the data do not require anything more complicated. We have compared the quiescent spectrum with an archival spectrum of Z Cam in standstill, obtained with ORFEUS. The standstill spectrum is described well by a disk accreting at disk = 7 × 1016 g s-1, where the errors depend on the assumed inclination. The quiescent spectra cover a full orbital period and are time-resolved to ~500 s. No variability was observed in the continuum during the observation, but the depth of many of the absorption lines increased between orbital phases 0.65 and 0.81. We attribute this effect to absorption by material associated with the accretion stream, which is easier to understand if the inclination is near the maximum allowed value of 68°.
Study of a Toroidal Lens

This letter presents a study of a toroidal-shaped lens following a Luneburg-like distribution of refractive index intended to multibeam radio frequency front ends. Due to its toroidal shape, this is a new model of lens that does not present any blind spot, as an opposite to any other kind of either spherical or cylindrical lens when adding both antennas and associated electronics. A sidelobe level reduction is proposed based on interface intrinsic impedance matching with magnetic–dielectric composite materials. It also proposed a set of numerical approximations of the main electromagnetic parameters, such as the half-power beamwidth in both the E- and H-planes, and the sidelobe level, and the directivity, in order to provide some basic guidelines for such a lens project. Given the new shape, the impacts of the curvature of the torus on the radiation pattern are also carried out. In order to prototype a toroidal lens with 3-D printing technology, a material has been fully characterized electromagnetically considering infill ratio variations in some effective dielectric constant models for multimaterial mixtures. The resulting toroidal lens has been characterized in far field, demonstrating a good agreement with the model and confirming its great potential for multibeam applications.
Dynamical (harmonic) interface stress field in the half-plane covered by the prestretched layer under a strip load

Within the framework of the piecewise homogeneous body model, by employing the three-dimensional linearized theory of elastic waves in initially stressed bodies the dynamical problem of the stress distribution in a half-plane covered with a prestretched layer is investigated. It is assumed that the free face plane of the covered layer is subjected to a uniformly distributed harmonic load acting on a strip extending to infinity in the x3 direction, which is perpendicular to the x1-x2 plane and is of width 2a in the x1 direction. The plane-strain state in the x1-x2 plane is analysed. The corresponding boundary-value problems are investigated by employing the exponential Fourier integral transformation. The numerical results regarding the interface normal stress distribution are presented. The influences of the problem parameters and pre-stretching of the covered layer on this distribution are analysed. Practical engineering application fields of the results are suggested.
Artificial Synaptic InGaZnO Thin-Film Transistor With Long Retention Behavior Using Al2O3/SiO2 Gate Insulator

We present a coplanar amorphous InGaZnO (a-IGZO) synaptic thin film transistor (TFT) with counterclockwise hysteresis using an aluminum oxide (Al2O3)/SiO2 gate insulator (GI). The excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), short-term plasticity (STP), and long-term plasticity, which are biological synaptic characteristics, are demonstrated by positive charge trapping in the Al2O3 layer. Long retention time can be possible by surface charge in the SiO2, a charge-blocking layer. As a result, multi-level channel conductance can be modulated with positive and negative gate pulses. These results prove synaptic a-InGaZnO TFT with Al2O3/SiO2 stack GI for high-density neuromorphic devices.
On Tests for Detecting Change in Mean

Procedures are considered for testing whether the means of each variable in a sequence of independent random variables can be taken to be the same, against alternatives that a shift might have occurred after some point r. Bayesian test statistics as well as some statistics depending on estimates of r are presented and their powers compared. Exact and asymptotic distribution functions are derived for some of the Bayesian statistics.
4-O-Methylascochlorin-Mediated BNIP-3 Expression Controls the Balance of Apoptosis and Autophagy in Cervical Carcinoma Cells

4-O-methylascochlorin (MAC) is a 4-fourth carbon-substituted derivative of ascochlorin, a compound extracted from a phytopathogenic fungus Ascochyta viciae. MAC induces apoptosis and autophagy in various cancer cells, but the effects of MAC on apoptosis and autophagy in cervical cancer cells, as well as how the interaction between apoptosis and autophagy mediates the cellular anticancer effects are not known. Here, we investigated that MAC induced apoptotic cell death of cervical cancer cells without regulating the cell cycle and promoted autophagy by inhibiting the phosphorylation of serine-threonine kinase B (Akt), mammalian target of rapamycin (mTOR), and 70-kDa ribosomal protein S6 kinase (p70S6K). Additional investigations suggested that Bcl-2/adenovirus E1B 19 kDa protein-interacting protein 3 (BNIP-3), but not Hypoxia-inducible factor 1 alpha (HIF-1α), is a key regulator of MAC-induced apoptosis and autophagy. BNIP-3 siRNA suppressed MAC-induced increases in cleaved- poly (ADP-ribose) polymerase (PARP) and LC3II expression. The pan-caspase inhibitor Z-VAD-FMK suppressed MAC-induced cell death and enhanced MAC-induced autophagy. The autophagy inhibitor chloroquine (CQ) enhanced MAC-mediated cell death by increasing BNIP-3 expression. These results indicate that MAC induces apoptosis to promote cell death and stimulates autophagy to promote cell survival by increasing BNIP-3 expression. This study also showed that co-treatment of cells with MAC and CQ further enhanced the death of cervical cancer cells.
