Consumers' preference for eco-friendly packaged products: pride vs guilt appeal

PurposeThis paper aims to examine the influence of eco-friendly packaging on consumers' responses. A research framework is examined to identify significant antecedents of eco-friendly packaging behaviour, namely environmental responsibility, knowledge, attitudes, and message framing, to determine their relative importance.Design/methodology/approachA set of hypotheses is tested across two studies.FindingsStudy 1 (n = 160) shows that attitude is an important mediator between consumers' environmental responsibility and environmental knowledge and intentions when adopting eco-friendly packaging. Furthermore, study 2 (n = 132) finds that where eco-friendly packaging is concerned, the advertised message has to be framed with a particular emotional appeal congruent to a specific psychographic trait to stimulate pro-environmental behavioural intention.Practical implicationsBased on the findings of this research, advertisers and environmental practitioners can utilise the correct type of message appeals to implement pro-environmental campaigns and programs for appropriate consumer segments effectively.Originality/valueAligning with the United Nations Sustainable Development Goals (SDGs), in particular, SDGs 12 on ensuring “responsible consumption and production”, the research findings have highlighted the importance of individual's environmental knowledge (eco-literacy) and responsibility as they act as precursors toward sustainable and responsible consumption.
Range extension and distribution update of Hsunycteris cadenai (Chiroptera: Phyllostomidae)

We report the northernmost collecting locality for the nectar-feeding bat Hsunycteris cadenai in the Colombian Biogeographic Chocó. This record extends the range of the species to 224 km north of the species type locality in Zabaletas river, department of Valle del Cauca, and 75 km west of Santa Cecilia, Risaralda. The specimen was collected on May 5, 2010, in a primary forest in Pacurita, Central Chocó. Our specimen of H. cadenai (CMCH 883) exhibits all the diagnostic characteristics of the species including the lateral projections on the postorbital region, a skull length greater than 20.0 mm, and a forearm shorter than 34.5 mm. We also present an updated distribution map for the species.
Data Mining Methods for Extracting Rumors Using Social Analysis Tools

Rumors are typically described as remarks whose true value is unknown. A rumor on social media has the potential to spread erroneous information to a large group of individuals. Those false facts will influence decision-making in a variety of societies. In online social media, where enormous amounts of information are simply distributed over a large network of sources with unverified authority, detecting rumors is critical. This research proposes that rumor detection be done using Natural Language Processing (NLP) tools as well as six distinct Machine Learning (ML) methods (Nave Bayes (NB), random forest (RF), K-nearest neighbor (KNN), Logistic Regression (LR), Stochastic Gradient Descent (SGD) and Decision Tree (DT)). The data set size for the suggested experiment was 16,865 samples. For pre-processing tokenization was used to separates each one of the tokens from the others. Normalization that removes all non-word tokens, deleting stop words was utilized to remove all unnecessary words, and stemming was used to obtain the stem of the tokens. Prior to using the six classification algorithms, the major feature extraction approach Term Frequency- Inverse Document Frequency (TF-IDF) was applied. The RF classifier performed better compared to all other classifiers with an accuracy of 99%, according to the data. Keywords: Machine learning, Text classification, Naïve Byes, RF, KNN, DT, Natural language processing, SGD).
The Impact of Psychological Factors on Sleep Quality among Public University Students in Klang Valley, Malaysia

A good night's sleep is essential for human mental and physical health, and chronic sleep deprivation has been related to impaired neurobehavioral function. This study aims to determine the relationship between internet addiction, loneliness, and cognitive workload on sleep quality among public university students in Klang Valley. A total of 400 respondents involved from three public universities in Klang valley. A self-administered questionnaire was used as a tool for data collection. The result revealed that most of the respondents had moderate level of internet addiction, loneliness, and cognitive workload. Meanwhile, the result also showed that majority of the respondents scored low level severity of sleep quality. In addition, cognitive workload, loneliness and internet addiction were positively correlated with sleep quality issues. Multiple regression analysis showed that loneliness and cognitive workload were significant predictors of sleep quality issues among the students with cognitive workload as the strongest predictor. This study concluded that undergraduate students’ cognitive workload, loneliness and internet addiction were important in influencing the undergraduate students’ sleep quality issues. By understanding the impact of these psychological factors on sleep quality particularly among the undergraduate students, it helped to minimize the possibility of undergraduate students' sleep quality issues in order to promote and maintain a healthy lifestyle for them. Thus, the impact and implications of this study will be discussed.
London penetration depth and pair breaking

The London penetration depth is evaluated for isotropic materials for any transport and pair-breaking Born scattering rates. Besides known results, a number of new features are found. The slope $|d\rho/d\theta |$ of the normalized superfluid density $\rho=\lambda^2(0)/\lambda^2(\theta)$ at the transition $\theta=T/T_c=1$ has a minimum near the value of the pair-breaking parameter separating gapped and gapless states. The low-$T$ exponentially flat part of $\rho$ for the s-wave materials is suppressed by increasing pair breaking. For strong $T_c $ suppression by magnetic impurities the "Homes scaling" $\lambda^{-2}(0) \propto \sigma T_c$ with $\sigma$ being the normal conductivity gives way to $\lambda^{-2}(0) \propto \sigma T_c^2$. For the d-wave order parameter, the transport and spin-flip Born scattering rates enter the theory only as a sum, in particular, they affect the $T_c$ depression in the same manner. We confirm that the linear low temperature behavior of $\rho$ in a broad range of the combined scattering parameter turns to the $T^2$ behavior only when the critical temperature is suppressed at least by a factor of 3 relative to the clean limit $T_{c0}$. Moreover, in this range, $\rho (\theta)$ is only weakly dependent on the scattering parameter, i.e. it is nearly universal.
Psychological Factors Associated With Return to Play After Ulnar Collateral Ligament Reconstruction: A Systematic Review

Background: The role of psychological factors in return to play (RTP) after ulnar collateral ligament (UCL) reconstruction remains unclear. Purpose: To perform a systematic review of the literature to (1) identify the specific psychological factors that affect RTP after UCL reconstruction and (2) determine the proportion of failures to RTP after UCL reconstruction because of psychological factors. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted. We queried the Cochrane Database of Systematic Reviews, Ovid/Embase, PubMed, and Web of Science databases to identify studies examining psychological factors and RTP after UCL reconstruction. Data pertaining to study characteristics and design, clinical and demographic characteristics, and psychological factors were collected. Patients were pooled across included studies, weighted means were calculated, and descriptive statistical analysis was performed. Results: A total of 8 studies consisting of 378 patients were included for analysis. The mean time to RTP was 12.2 months, and the overall RTP rate was 89.4%. Psychological factors affecting RTP included loss of interest, fear of reinjury, individual personality traits, personal reasons, and psychological concerns. While clinical factors accounted for 46.2% (n = 24) of failures to RTP, psychological factors comprised 40.4% (n = 21) of the reasons for failure to RTP. The most commonly cited psychological factors affecting RTP were loss of interest (n = 15 [28.8%]) and fear of reinjury (n = 3 [5.8%]). Conclusion: Psychological factors represented a substantial proportion of failures to RTP after UCL reconstruction, especially in adolescent athletes. Future prospective studies and multicenter initiatives are needed to more thoroughly evaluate the psychological concerns of patients before and after UCL reconstruction.
FOUR HIGHLY LUMINOUS MASSIVE STAR-FORMING REGIONS IN THE NORMA SPIRAL ARM. I. MOLECULAR GAS AND DUST OBSERVATIONS

We report molecular line and dust continuum observations, made with the Swedish-ESO Submillimeter Telescope, toward four young high-mass star-forming regions associated with highly luminous ( 6\times 10^5\,{\cal L}_{\odot }$? >) Infrared Astronomical Satellite sources (15290−5546, 15502−5302, 15567−5236, and 16060−5146). Molecular emission was mapped in three lines of CS (J = 2 → 1, 3 → 2, and 5 → 4), two lines of SiO (J = 2 → 1 and 3 → 2), two rotational transitions of CH3OH (Jk = 3k → 2k and 2k → 1k), and in the C34S(J = 3 → 2) line. In addition, single spectra at the peak position were taken in the CO(J = 1 → 0), 13CO(J = 1 → 0), and C18O(J = 1 → 0) lines. We find that the luminous star-forming regions are associated with molecular gas and dust structures with radii of typically 0.5 pc, masses of ∼5 × 103 M☉, column densities of ∼5 × 1023 cm−2, molecular hydrogen densities of typically ∼2 × 105 cm−3, and dust temperatures of ∼40 K. The 1.2 mm dust continuum observations further indicate that the cores are centrally condensed, having radial density profiles with power-law indices in the range 1.9–2.3. We find that under these conditions dynamical friction by the gas plays an important role in the migration of high-mass stars toward the central core region, providing an explanation for the observed stellar mass segregation within the cores. The CS profiles show two distinct emission components: a bright component, with line widths of typically 5 km s−1 (FWHM), and a weaker and wider velocity component, which typically extends up to ±13 km s−1 from the ambient cloud velocity. The SiO profiles also show emission from both components, but the intensity of the pedestal feature relative to that of the bright component is stronger than for CS. The narrow SiO component is likely to trace warm ambient gas close to the recently formed massive stars, whereas the high velocity emission indicates mass outflows produced by either the expansion of the H ii regions, stellar winds, and/or collimated outflows. We find that the abundances of CS, CH3OH, and SiO, relative to H2, in the warm ambient gas of the massive cores are typically 4 × 10−8, 6 × 10−9, and 5 × 10−11, respectively.
PATCHY BLAZAR HEATING: DIVERSIFYING THE THERMAL HISTORY OF THE INTERGALACTIC MEDIUM

TeV-blazars potentially heat the intergalactic medium (IGM) as their gamma rays interact with photons of the extragalactic background light to produce electron–positron pairs, which lose their kinetic energy to the surrounding medium through plasma instabilities. This results in a heating mechanism that is only weakly sensitive to the local density, and therefore approximately spatially uniform, naturally producing an inverted temperature–density relation in underdense regions. In this paper we go beyond the approximation of uniform heating and quantify the heating rate fluctuations due to the clustered distribution of blazars and how this impacts the thermal history of the IGM. We analytically compute a filtering function that relates the heating rate fluctuations to the underlying dark matter density field. We implement it in the cosmological code GADGET-3 and perform large-scale simulations to determine the impact of inhomogeneous heating. We show that because of blazar clustering, blazar heating is inhomogeneous for z ≳ 2. At high redshift, the temperature–density relation shows an important scatter and presents a low temperature envelope of unheated regions, in particular at low densities and within voids. However, the median temperature of the IGM is close to that in the uniform case, albeit slightly lower at low redshift. We find that blazar heating is more complex than initially assumed and that the temperature–density relation is not unique. Our analytic model for the heating rate fluctuations couples well with large-scale simulations and provides a cost-effective alternative to subgrid models.
NEW X-RAY OBSERVATIONS OF THE GEMINGA PULSAR WIND NEBULA

Previous observations of the middle-aged pulsar Geminga with XMM-Newton and Chandra have shown an unusual pulsar wind nebula (PWN), with a 20″ long central (axial) tail directed opposite to the pulsar's proper motion and two 2′ long, bent lateral (outer) tails. Here, we report on a deeper Chandra observation (78 ks exposure) and a few additional XMM-Newton observations of the Geminga PWN. The new Chandra observation has shown that the axial tail, which includes up to three brighter blobs, extends at least 50″ (i.e., 0.06d250 pc) from the pulsar (d250 is the distance scaled to 250 pc). It also allowed us to image the patchy outer tails and the emission in the immediate vicinity of the pulsar with high resolution. The PWN luminosity, L0.3-8 keV ∼ 3 × 1029d2250 erg s−1, is lower than the pulsar's magnetospheric luminosity by a factor of 10. The spectra of the PWN elements are rather hard (photon index Γ ∼ 1). Comparing the two Chandra images, we found evidence of PWN variability, including possible motion of the blobs along the axial tail. The X-ray PWN is the synchrotron radiation from relativistic particles of the pulsar wind (PW); its morphology is connected with the supersonic motion of Geminga. We speculate that the outer tails are either a sky projection of the limb-brightened boundary of a shell formed in the region of contact discontinuity, where the wind bulk flow is decelerated by shear instability, or polar outflows from the pulsar bent by the ram pressure from the interstellar medium. In the former case, the axial tail may be a jet emanating along the pulsar's spin axis, perhaps aligned with the direction of motion. In the latter case, the axial tail may be the shocked PW collimated by ram pressure.
The seismic properties of low-mass He-core white dwarf stars

Context. In recent years, many low-mass (0.45 M� ) white dwarf stars expected to harbor He cores have been detected in the field of the Milky Way and in several galactic globular and open clusters. Until recently, no objects of this kind showed pulsations. This situation has changed recently with the exciting discovery of SDSS J184037.78+642312.3, the first pulsating low-mass white dwarf star. Aims. Motivated by this extremely important finding, and in view of the very valuable asteroseismological potential of these objects, we present here a detailed pulsational study applied to low-mass He-core white dwarfs with masses ranging from 0.17 to 0.46 M� , based on full evolutionary models representative of these objects. This study is aimed to provide a theoretical basis from which to interpret future observations of variable low-mass white dwarfs. Methods. The background stellar models on which our pulsational analysis was carried out were derived by taking into account the complete evolutionary history of the progenitor stars, with special emphasis on the diffusion processes acting during the white dwarf cooling phase. We computed nonradial g-modes to assess the dependence of the pulsational properties of these objects with stellar parameters such as the stellar mass and the effective temperature, and also with element diffusion processes. We also performed a g -a ndp-mode pulsational stability analysis on our models and found well-defined blue edges of the instability domain, where these stars should start to exhibit pulsations.
The Chamaeleon II low-mass star-forming region: radial velocities, elemental abundances, and accretion properties

Radial velocities, elemental abundances, and accretion properties of members of star-forming regions (SFRs) are important for understanding star and planet formation. While infrared observations reveal the evolutionary status of the disk, optical spectroscopy is fundamental to acquire information on the properties of the central star and on the accretion characteristics. 2MASS archive data and the Spitzer c2d survey of the Chamaeleon II dark cloud have provided disk properties of a large number of young stars. We complement these data with spectroscopy with the aim of providing physical stellar parameters and accretion properties. We use FLAMES/UVES+GIRAFFE observations of 40 members of Cha II to measure radial velocities through cross-correlation technique, Li abundances by means of curves of growth, and for a suitable star elemental abundances of Fe, Al, Si, Ca, Ti, and Ni using the code MOOG. From the equivalent widths of the Halpha, Hbeta, and the HeI-5876, 6678, 7065 Angstrom emission lines, we estimate the mass accretion rates, dMacc/dt, for all the objects. We derive a radial velocity distribution for the Cha II stars ( =11.4+-2.0 km/s). We find dMacc/dt prop. to Mstar^1.3 and to Age^(-0.82) in the 0.1-1.0 Msun mass regime, and a mean dMacc/dt for Cha II of ~7*10^(-10) Msun/yr. We also establish a relationship between the HeI-7065 Angstrom line emission and the accretion luminosity. The radial velocity distributions of stars and gas in Cha II are consistent. The spread in dMacc/dt at a given stellar mass is about one order of magnitude and can not be ascribed entirely to short timescale variability. Analyzing the relation between dMacc/dt and the colors in Spitzer and 2MASS bands, we find indications that the inner disk changes from optically thick to optically thin at dMacc/dt~10^(-10) Msun/yr. Finally, the disk fraction is consistent with the age of Cha II.
THE CHALLENGE OF THE LARGEST STRUCTURES IN THE UNIVERSE TO COSMOLOGY

Large galaxy redshift surveys have long been used to constrain cosmological models and structure formation scenarios. In particular, the largest structures discovered observationally are thought to carry critical information on the amplitude of large-scale density fluctuations or homogeneity of the universe, and have often challenged the standard cosmological framework. The Sloan Great Wall (SGW) recently found in the Sloan Digital Sky Survey (SDSS) region casts doubt on the concordance cosmological model with a cosmological constant (i.e., the flat ΛCDM model). Here we show that the existence of the SGW is perfectly consistent with the ΛCDM model, a result that only our very large cosmological N-body simulation (the Horizon Run 2, HR2) could supply. In addition, we report on the discovery of a void complex in the SDSS much larger than the SGW, and show that such size of the largest void is also predicted in the ΛCDM paradigm. Our results demonstrate that an initially homogeneous isotropic universe with primordial Gaussian random phase density fluctuations growing in accordance with the general relativity can explain the richness and size of the observed large-scale structures in the SDSS. Using the HR2 simulation we predict that a future galaxy redshift survey about four times deeper or with 3 mag fainter limit than the SDSS should reveal a largest structure of bright galaxies about twice as big as the SGW.

The best formula F5 was 10% oil and 90% surfactant -co surfactant mixture (S mix) in ratio 4:1 (tween/ Propylene glycol), showed 25 nm particle size, 0.098 polydispersity index, 10 times improvement in drug release rate than pure drug powder, and about 10 time prolongation of drug clotting time in the in-vivo study. Conclusion: the preparation of Ticagrelor as self-nano emulsion improve both the aqueous solubility of drug and the bioavailability.
Metabolism of Arsenic in Human by AS3MT Gene

The AS3MT may be the most significant protein for the methylation of chemical elements species. The transfer of methyl radical from S-adenosyl-L-methionine (AdoMet) to powerfulness arsenical (AsIII) is catalyzed by the AS3MT that is critical for arsenic metabolism in humans. Since the AS3MT genetic polymorphism is linked to arsenic resistance, the association between the single ester polymorphism (SNP) and AS3MT inorganic arsenic (iAs) metabolism is being studied. Additionally, we tend to compared chemical action properties of recombinant human AS3MT and AS3MT/M287T. In reaction S-adenosylmethionine, arsenite, or methylarsonous acid (MAsIII) as substrates and endogenous reductants, together with glutathione (GSH), a thioredoxin enzyme (TR) system and tris(2-carboxyethyl) pesticide complex (TCEP). By victimization of either TR or Trx or NADPH or TCEP, AS3MT catalyzes the conversion of iAsIII to MAsIII then to methyl radical sonic acid (MAsV), dimethylarsinous acid (DMAsIII), and diethylarsinic acid (DMAsV). The Cys156 and Cys206 gift in similarity model forms the binding website for AsIII. Cys32 and Cys61 are linked by disulphidebond. The most important product in the initiative of methylation is MAsIII which remains sure to protein until it gets methylated. The product is a lot of hepatotoxic and more malignant neoplastic disease powerfulness methyl arsenicals, however, arsenic undergoes oxidation and reduction as enzyme-bound intermediates.
