description: Digital ecosystems, or IT-ecosystems (ITEs), are composed of multiple and independent entities such as individuals, organizations, services, software, and applications. Together, these elements create a number of new independent systems that operate and communicate with their own infrastructure (man to machine; machine to machine; person to person), sharing one or several missions. A better understanding of how ITEs and their interconnected components create benefits and added value for different types of consumers is of particular importance to the establishment of digital environments and to managing their resources. Considering different components of perceived trust in ITEs, we rely in this paper on a multi-dimensional framework of trust effects that includes system-centric as well as user-centric determinants of trust. Based on our conceptual model, we develop two sets of propositions. The first ones address technological drivers of trust in ITEs, whereas the second set of propositions considers individual as well as social drivers of trust. The model and propositions are discussed with reference to preliminary empirical results as well as to future research steps and business implications.

description: Assessment in the 2013 curriculum leads more to the assessment of knowledge and attitude. The ability of cooperation is categorized as part of the social skills and attitudes that learners need to develop. One approach to learning that can be used to develop the ability of cooperation is the CTL approach. The CTL approach links material to the real situation of learners and provides an opportunity to work together to solve problems. Android is one form of sophistication of Information and Communication Technology (ICT) which is generally owned by all circles including learners, and can be used as a media of learning. This study aims to measure the students’ cooperation ability during learning using the physics learning toolsof CTL approach assisted android. A type of pre-experimental research was used in this study. 32 students of XI MIA 4 were used as study subjects. The results showed: (1) the physics learning tools that are made feasible to use with the category of validity are very well grounded, (2) the students' cooperation ability is in a very good category after learning to use the CTL approach assisted android.

description: The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M dwarfs, despite their critical importance to predicting and interpreting the spectra of potentially habitable planets as they are obtained in the coming decades. Using observations from the Hubble Space Telescope, we present a study of the UV radiation fields around nearby M dwarf planet hosts that covers both FUV and NUV wavelengths. The combined FUV+NUV spectra are publically available in machine-readable format. We find that all six exoplanet host stars in our sample (GJ 581, GJ 876, GJ 436, GJ 832, GJ 667C, and GJ 1214) exhibit some level of chromospheric and transition region UV emission. No "UV quiet" M dwarfs are observed. The bright stellar Ly-alpha emission lines are reconstructed, and we find that the Ly-alpha line fluxes comprise ~37-75% of the total 1150-3100A flux from most M dwarfs; > 10^{3} times the solar value. The F(FUV)/F(NUV) flux ratio, a driver for abiotic production of the suggested biomarkers O2 and O3, is shown to be ~0.5-3 for all M dwarfs in our sample, > 10^{3} times the solar ratio. For the four stars with moderate signal-to-noise COS time-resolved spectra, we find UV emission line variability with amplitudes of 50-500% on 10^{2} - 10^{3} s timescales. Finally, we observe relatively bright H2 fluorescent emission from four of the M dwarf exoplanetary systems (GJ 581, GJ 876, GJ 436, and GJ 832). Additional modeling work is needed to differentiate between a stellar photospheric or possible exoplanetary origin for the hot (T(H2) \approx 2000-4000 K) molecular gas observed in these objects.

description: We present a study of the prevalence of optical and radio nuclear activity with respect to the environment and interactions in a sample of SDSS galaxies. We defined a local density parameter and a tidal forces estimator and used a cluster richness estimator from the literature. The possible correlations between these parameters were removed using a principal component analysis. We applied a stratified statistical method that takes into account the effect of possible confounding factors like the galaxy mass. We found that the prevalence of optical AGN is a factor 2-3 lower in the densest environments, but increases by a factor of ~2 in the presence of strong one-on-one interactions. The importance of galaxy interactions decreases from star-forming nuclei (SFN) to Seyferts to LINERs to passive galaxies, in accordance with previous suggestions of an evolutionary time-sequence. The fraction of radio AGN increases strongly towards denser environments, and is enhanced by galaxy interactions. Overall, the results agree with a scenario in which the mechanisms of accretion into the black hole are determined by the presence and nature of a supply of gas, which in turn is controlled by the local density of galaxies and their interactions. A plentiful cold gas supply is required to trigger SFN, optical AGN and radiatively-efficient radio AGN. This is less common in the cold-gas-poor environments of groups and clusters, but is enhanced by one-on-one interactions which result in the flow of gas into nuclear regions; these two factors compete against each other. In the denser environments where cold gas is rare, cooling hot gas can supply the nucleus at a sufficient rate to fuel low-luminosity radiatively-inefficient radio AGN. However, the increased prevalence of these AGN in interacting galaxies suggests that this is not the only mechanism by which radiatively-inefficient AGN can be triggered.

description: CELLO is a new learning method resulting from the integration of the CLL method and a mobile app called Orai. It is applied in teaching and learning of speaking especially in fostering students’ confidence and speaking ability. This research is intended to explore the use of CELLO in assisting students to increase their speaking ability. The obtained data that were gathered from questionnaire and tests showed that the CELLO method could improve EFL students’ speaking ability. Based on the findings, implementing the CELLO method is strongly recommended in teaching speaking and it shoul be extended for teaching-learning other language skills, such as phonology, conversation skills, reading aloud, and interpreting.

description: The purpose of the study was to assess the influence of real-time auditory feedback on knee proprioception. Thirty healthy participants were randomly allocated to control (n = 15), and experimental group I (15). The participants performed an active knee-repositioning task using their dominant leg, with/without additional real-time auditory feedback where the frequency was mapped in a convergent manner to two different target angles (40 and 75°). Statistical analysis revealed significant enhancement in knee re-positioning accuracy for the constant and absolute error with real-time auditory feedback, within and across the groups. Besides this convergent condition, we established a second divergent condition. Here, a step-wise transposition of frequency was performed to explore whether a systematic tuning between auditory-proprioceptive repositioning exists. No significant effects were identified in this divergent auditory feedback condition. An additional experimental group II (n = 20) was further included. Here, we investigated the influence of a larger magnitude and directional change of step-wise transposition of the frequency. In a first step, results confirm the findings of experiment I. Moreover, significant effects on knee auditory-proprioception repositioning were evident when divergent auditory feedback was applied. During the step-wise transposition participants showed systematic modulation of knee movements in the opposite direction of transposition. We confirm that knee re-positioning accuracy can be enhanced with concurrent application of real-time auditory feedback and that knee re-positioning can modulated in a goal-directed manner with step-wise transposition of frequency. Clinical implications are discussed with respect to joint position sense in rehabilitation settings.

description: Rapidly cooling a liquid may result in a glass transition, creating an amorphous solid whose shear and bulk moduli are finite. Even when done with constant density, these resulting moduli depend strongly on the rate of cooling. Understanding this phenomenon calls for analyzing separately the "Born term" that exists also in perfectly ordered materials and the contributions of the "excess modes" that result from glassy disorder. We show that the Born term is very insensitive to the cooling rate, and all the variation in the shear modulus is due to the excess modes. We argue that this approach provides a quantitative understanding of the cooling rate dependence of a basic linear response coefficient, i.e. the shear modulus.

description: This paper presents a small theoretical model to compare school systems that segregate students by ability ("tracking") with comprehensive ones, which allow for mixing of differently skilled students into same classes. The outcomes of interest are the achievement levels of weaker and better students, and the average achievement of all students. In the model, the instructional pace is tailored to the skill distribution of a class, and higher-Achieving peers are an additional source of learning. The results show that differences in both the share of high-Achievers and degree of interaction between student types can explain the mixed (quasi-)experimental evidence on the effect of de-Tracking on student achievement. As changes in peer quality affect good and weak students' achievement in very different ways, the term "peer effect" should be used with caution. © 2017 Walter de Gruyter GmbH, Berlin/Boston.

description: Transitioning to a net-zero-emission future will require a transformation of New Zealand’s economy and society. The costs of meeting the Government’s emissions reduction targets could be large, and new technologies will be required. In coming decades, petroleum products will continue to play an important role in society, both for transportation and petrochemicals (and potentially some industrial heat applications). The dilemma we face is that our current petroleum and natural gas resources will only last for around another decade at current rates of extraction, new exploration opportunities are limited and global competition for the labour and capital to develop new resources is fierce. Without a continued supply of natural gas and other petroleum products, New Zealand may not be able to engineer and afford the transition to a net-zero carbon economy. A workshop was held in Dunedin on the 7th August 2019 to explore the role that a hypothetical, large gas discovery offshore of Te Waipounamu / South Island would have on the transition to a low-emissions economy. The goal was to provide a clearer understanding around where the experts agree, and where there is a need for more research and debate. The small-group session was based around decision trees and timelines. It identified a series of conditions whereby future natural gas development in New Zealand would be more likely to receive social licence and be publicly acceptable. These include:
feasible and cost-effective carbon dioxide capture and storage;
production of New Zealand natural gas reserves that would reduce overall global emissions by offsetting coal (that produces more CO2 per unit of useful energy), both internationally and locally;
sufficient demand for natural gas, both internationally and locally;
an economically feasible domestic distribution network (presently only on the North Island)
adaptability of utilising natural gas infrastructure for hydrogen in the future;
opportunities for the government to influence development through contracts and licenses;
effective management of local environmental risks;
social license to produce and consume, or to export, natural gas after 2030; and
decision-making processes consistent with the principles of Te Tiriti o Waitangi. (auth)

description: To analyze contemporary costs of HIV health care and the cost distribution across lines of combination antiretroviral therapy (cART). To identify variations in expenditures with patient characteristics and to identify main cost determinants. To compute cost ratios between patients with varying characteristics.Empirical data on costs are collected in Germany within a 2-year prospective observational noninterventional multicenter study. The database contains information for 1154 HIV-infected patients from 8 medical centers.Means and standard deviations of the total costs are estimated for each cost fraction and across cART lines and regimens. The costs are regressed against various patient characteristics using a generalized linear model. Relative costs are calculated using the resultant coefficients.The average annual total costs (SD) per patient are &OV0556;22,231.03 (8786.13) with a maximum of &OV0556;83,970. cART medication is the major cost fraction (83.8%) with a mean of &OV0556;18,688.62 (5289.48). The major cost-driving factors are cART regimen, CD4-T cell count, cART drug resistance, and concomitant diseases. Viral load, pathology tests, and demographics have no significant impact. Standard non-nucleoside reverse transcriptase inhibitor-based regimens induce 28% lower total costs compared with standard PI/r regimens. Resistance to 3 or more antiretroviral classes induces a significant increase in costs.HIV treatment in Germany continues to be expensive. Majority of costs are attributable to cART. Main cost determinants are CD4-T cells count, comorbidity, genotypic antiviral resistance, and therapy regimen. Combinations of characteristics associated with higher expenditures enhance the increasing effect on the costs and induce high cost cases.

description: To reduce potential food hazards and increase the image of Thai horticultural products abroad, the Thai government introduced public standards of Good Agricultural Practices (Q-GAP). What makes orchid and mango producers in Thailand adopt Q-GAP standards and how do these affect their income and export shares? Primary data from 400 certified and non-certified orchid and mango producers was collected from main exporting provinces in Thailand. The binary probit model estimations show that it is the orchid and mango producers with higher education, and more physical and social capital who tend to comply with Q-GAP standards. Results from the Propensity Score Matching approach reveal that adoption of public GAP standards results in positive income effects for mango producers, but not for orchid producers. This can be explained by the fact that certified mango producers can sell their products to high-value retail chains which offer higher prices for their products, while certified and non-certified orchid producers cooperate with traders from the same value chain.
MITIGATING CORPORATE FAILURES IN LISTED CONSUMER GOODS FIRMS: THE INFLUENCE OF AUDIT FIRM ATTRIBUTES IN NIGERIA

Subjects: Audit Firm Physiognomies, Corporate Failures, Audit Fee, Audit Firm Size, Audit Firm Tenure and Altman's Z-score

description: The study examined audit firm physiognomies as a contrivance for mitigating corporate failures in listed consumer goods firms in Nigeria. The specific objective of the study was to ascertain the extent to which audit fee, audit firm size and audit firm tenure help to prevent the likelihood of corporate failure. The likelihood of corporate failure was measured using Altman’s Z-score framework. The study employed an ex-post facto research design. All twenty-one firms listed under the consumer goods sector of the Nigerian Exchange Group comprised the population of the study. The study utilized purposive sampling to select 16 firms that made up the sample size. Secondary data were sourced from the audited financial statements and annual reports of the firms over a 10 year period, from 2012 to the 2021. In addition to the descriptive analysis, the study employed ordinary regression method to test the hypotheses. The findings revealed that: larger audit fee significantly helps to mitigate the likelihood of corporate failure (p-value = 0.0000); larger audit firm size significantly helps to mitigate the likelihood of corporate failure (p-value = 0.0036); but higher audit firm tenure worsens the likelihood of corporate failure although this effect is not significant (p-value = 0.0923). In conclusion, a high-quality audit can help companies to identify potential risks and take necessary measures to mitigate them, thereby reducing the likelihood of financial distress. The study recommends that firms in Nigeria should consider investing in high-quality audits, even if it means incurring higher audit fees which can help to enhance the accuracy and credibility of their financial statements, thereby fostering greater investor confidence and securing longterm financial stability

Using an analytical stub formalism, we show the emergence of a depletion/amplification of conductance fluctuations as a function of tunnel barriers, for both parametric variations of electron energy or magnetoconductance fields. Furthermore, even for pure Dyson ensembles, correlation functions of conductance fluctuations in chaotic quantum dots can exhibit anti-correlation. Experimental support to our findings is pointed out.

description: In this paper we investigate a method to reduce the number of computations and associated activations in Convolutional Neural Networks (CNN) by using bitmaps. The bitmaps are used to mask the input images to the network that fall within a rectangular window but do not fall within the boundaries of the objects the network is being trained upon. The mask has the effect of rendering the operations on these portions of the training images trivial. The thesis is that applying this approach to CNNs will not degrade accuracy while at the same time reducing the computational workload and reducing memory footprint. We found that we can remove up to 60% of the input images and see no decrease in accuracy. This leads to activation sparsity that can be exploited using a hardware accelerator to speedup training and inference, and decrease energy consumed.

description: In contrast to mineral topsoils, in subsoils the origin and processes leading to the formation and stabilization of organic matter (OM) are still not well known. This study addresses the fate of litter-derived carbon (C) in whole soil profiles with regard to the conceptual cascade model, which proposes that OM formation in subsoils is linked to sorption–microbial processing–remobilization cycles during the downward migration of dissolved organic carbon (DOC). Our main objectives were to quantify the contribution of recent litter to subsoil C stocks via DOC translocation and to evaluate the stability of litter-derived OM in different functional OM fractions. A plot-scale stable isotope-labeling experiment was conducted in a temperate beech forest by replacing the natural litter layer with 13C enriched litter on an area of 20 m2 above a Dystric Cambisol. After 22 months of field exposure, the labeled litter was replaced again by natural litter and soil cores were drilled down to 180 cm soil depth. Water extraction and density fractionation were combined with stable isotope measurements in order to link the fluxes of recent litter-derived C to its allocation into different functional OM fractions. A second sampling was conducted 18 months later to further account for the stability of translocated young litter-derived C. Almost no litter-derived particulate OM (POM) entered the subsoil, suggesting root biomass as the major source of subsoil POM. The contribution of aboveground litter to the formation of mineral-associated OM (MAOM) in topsoils (0–10 cm) was 1.88±0.83 g C m−2 and decreased to 0.69±0.19 g C m−2 in the upper subsoil (10–50 cm) and 0.01±0.02 g C m−2 in the deep subsoil >100 cm soil depth during the 22 months. This finding suggests a subordinate importance of recent litter layer inputs via DOC translocation to subsoil C stocks, and implies that most of the OM in the subsoil is of older age. Smaller losses of litter-derived C within MAOM of about 66 % compared to POM (77 %–89 %) over 18 months indicate that recent carbon can be stabilized by interaction with mineral surfaces; although the overall stabilization in the sandy study soils is limited. Our isotope-labeling approach supports the concept of OM undergoing a sequence of cycles of sorption, microbial processing, and desorption while migrating down a soil profile, which needs to be considered in models of soil OM formation and subsoil C cycling.

description: Strongly correlated quantum systems can exhibit exotic behavior controlled by topology. We predict that the ν=1/2 fractional Chern insulator arises naturally in a two-dimensional array of driven, dipolar-interacting spins. As a specific implementation, we analyze how to prepare and detect synthetic gauge potentials for the rotational excitations of ultra-cold polar molecules trapped in a deep optical lattice. While the orbital motion of the molecules is pinned, at finite densities, the rotational excitations form a fractional Chern insulator. We present a detailed experimental blueprint for KRb, and demonstrate that the energetics are consistent with near-term capabilities. Prospects for the realization of such phases in solid-state dipolar systems are discussed as are their possible applications.

description: Methane is produced in the rumen of ruminant livestock by methanogens, accounting for approximately 14.5% of anthropogenic greenhouse gas emissions in terms of global warming potential. The rumen contains a diversity of methanogens species, and only a few of these have been cultured. Immunomagnetic capture technology (ICT) is a simple and effective method to capture and concentrate target organisms in samples containing complex microflora. We hypothesized that antibody-coated magnetic beads could be used to demonstrate antibody specificity and cross-reactivity to methanogens in rumen samples. Sheep polyclonal antibodies raised against four isolates of rumen dwelling methanogens, Methanobrevibacter ruminantium strain M1, Methanobrevibacter sp. AbM4, Methanobrevibacter sp. D5, and Methanobrevibacter sp. SM9 or an equal mix of all four isolates, were used to coat paramagnetic beads. ICT was used together with flow cytometry and qPCR to optimize key parameters: the ratio of antibody to beads, coupling time between antibody and paramagnetic beads to produce immunomagnetic beads (IMBs), and optimal incubation time for the capture of methanogen cells by IMBs. Under optimized conditions, IMBs bound strongly to their respective isolates and showed a degree of cross-reactivity with isolates of other Methanobrevibacter spp. in buffer and in rumen fluid, and with resident methanogens in rumen content samples. The evidence provided here indicates that this method can be used to study the interaction of antibodies with antigens of rumen methanogens, to understand antigen cross-reactivity and antibody binding efficiency for the evaluation of antigens used for the development of a broad-spectrum anti-methanogen vaccine for the abatement of methane production.

description: Stimulated Raman scattering (SRS) in its strongly nonlinear, kinetic regime is controlled by a technique of deterministic, strong temporal modulation and spatial scrambling of laser speckle patterns, called Spike Trains of Uneven Duration and Delay (STUD pulses) [B. Afeyan and S. Hüller, Phys. Rev. Lett. (submitted)]. Kinetic simulations show that use of STUD pulses may decrease SRS reflectivity by more than an order of magnitude over random-phase-plate (RPP) or induced-spatial-incoherence (ISI) beams of the same average intensity and comparable bandwidth.

description: The experimental determination of freeze-out temperatures and densities from the yields of light elements emitted in heavy ion collisions is discussed. Results from different experimental approaches are compared with those of model calculations carried out with and without the inclusion of medium effects. Medium effects become of relevance for baryon densities above $\approx 5 \times 10^{-4}$ fm$^{-3}$. A quantum statistical (QS) model incorporating medium effects is in good agreement with the experimentally derived results at higher densities. A densitometer based on calculated chemical equilibrium constants is proposed.

description: The IMACS Cluster Building Survey uses the wide field spectroscopic capabilities of the IMACS spectrograph on the 6.5m Baade Telescope to survey the large-scale environment surrounding rich intermediate-redshift clusters of galaxies. The goal is to understand the processes which may be transforming star-forming field galaxies into quiescent cluster members as groups and individual galaxies fall into the cluster from the surrounding supercluster. This first paper describes the survey: the data taking and reduction methods. We provide new calibrations of star formation rates derived from optical and infrared spectroscopy and photometry. We demonstrate that there is a tight relation between the observed star formation rate per unit B luminosity, and the ratio of the extinctions of the stellar continuum and the optical emission lines. With this, we can obtain accurate extinction-corrected colors of galaxies. Using these colors as well as other spectral measures, we determine new criteria for the existence of ongoing and recent starbursts in galaxies.

Thermodynamics of the apparent horizon in infrared modified Horava-Lifshitz gravity

description: It is well known that by applying the first law of thermodynamics to the apparent horizon of a Friedmann-Robertson-Walker universe, one can derive the corresponding Friedmann equations in Einstein, Gauss-Bonnet, and more general Lovelock gravity. Is this a generic feature of any gravitational theory? Is the prescription applicable to other gravities? In this paper we would like to address the above questions by examining the same procedure for Horava-Lifshitz gravity. We find that in Horava-Lifshitz gravity, this approach does not work and we fail to reproduce a corresponding Friedmann equation in this theory by applying the first law of thermodynamics on the apparent horizon, together with the appropriate expression for the entropy in Horava-Lifshitz gravity. The reason for this failure seems to be due to the fact that Horava-Lifshitz gravity is not diffeomorphism invariant, and thus, the corresponding field equation cannot be derived from the first law around horizon in the spacetime. Without this, it implies that the specific gravitational theory is not consistent, which shows an additional problematic feature of Horrava-Lifshitz gravity. Nevertheless, if we still take the area formula of geometric entropy and regard Horava-Lifshitz sector in the Friedmann equation as an effective dark radiation, we are able to extract the corresponding Friedmann equation from the first law of thermodynamics.

description: Auckland is the largest city in New Zealand with 1.6 million residents. This major metropolitan region is situated upon the Auckland Volcanic Field (AVF), posing a considerable risk to the city’s population and essential services. On 17 December 2018, a workshop jointly run by DEVORA (Determining Volcanic Risk in Auckland) and Auckland Emergency Management (AEM) was held to discuss evacuation decision-support options in the event of a volcanic crisis in Auckland. The workshop brought together emergency management officials, members of the emergency services, transportation managers, academics and researchers. Participants discussed existing decision-making processes and communication pathways before being presented with how ongoing research could support decision-makers with volcanic crisis planning and management. An exercise was conducted to learn the types of decisions and related information requirements of different groups at different stages of a crisis. The exercise focused on three early stages of an existing AVF eruption crisis scenario centred on Birkenhead: Initial unrest; heightened unrest; and initial eruption phase. Each stage of the scenario was presented to groups along with a series of questions relating to their likely actions based on the information presented. The purpose of the exercise was to learn what type of information would be required at each step, and to identify how ongoing research into a quantitative decision-support framework using cost-benefit analysis could support decision-makers in a future AVF eruption. The exercise revealed that risk to life is a primary consideration for making an evacuation decision; the declaration of a state of emergency is critical before making an evacuation call; key locations and services critical for crisis management exist and can be identified in advance of a crisis; and a staged evacuation would likely be recommended. The findings from this workshop will support ongoing research exploring how hazard and risk information can best be presented to support decision-makers in the event of an evacuation during an AVF event.
