Dynamic Activity Analysis Model Based Win-Win Development Forecasting Under the Environmental Regulation in China
No full textPorter Hypothesis states that environmental regulation may lead to win-win opportunities, that is, improve the productivity and reduce the undesirable output simultaneously. Based on directional distance function, this paper proposes a novel dynamic activity analysis model to forecast the possibilities of win-win development in Chinese Industry between 2009 and 2049. The evidence reveals that the appropriate energy-saving and emission-abating regulation will result in both the improvement in net growth of potential output and the steadily increasing growth of total factor productivity. This favors Porter Hypothesis.Dynamic Activity Analysis Model, Energy-Saving and Emission-Abating, Environmental Regulation, Win-Win Development
Conversational noise reduction as a win-win for ecotourists and rain forest birds in Peru
No full textFor all its positive attributes, the recent expansion of ecotourism has resulted in greater influxes of people into natural areas, causing a range of impacts including behavioral disruptions among wildlife. How animals respond to conversation is poorly understood, but noise reduction may reduce the impact of ecotourists while simultaneously enhancing their experience with higher wildlife encounter rates. We tested the response of a rain forest bird community to noise by playing a recorded conversation while conducting point censuses in a terra firme forest in Tambopata, Peru. Fifty decibel conversation (approximately library speaking volume) caused declines of 35 percent in total detections and 33 percent in detected species richness. Birds reacted similarly to 60 dB (approximately the volume of an excited child): average detections declined by 39 percent and detected species richness by 37 percent. Specifically, noise-induced detection declines were manifest both in decreased vocalizations (37% decline) and decreased physical sightings (44% decline). Lowered detection frequencies indicate behavioral shifts. As vocalization is involved in territory defense, breeding behavior, and predator detection, strong noise responsiveness indicates potential harm for birds. Insectivores were the most affected bird guild, raising conservation concerns, as insectivorous birds are sensitive to habitat modification. Birds reacted strongly to noise both near an established ecotourist lodge and in an intact reserve, indicating an absence of habituation. Thus, as a method for reducing ecotourism?s footprint on native fauna and improving tourist satisfaction with increased wildlife sightings, noise reduction seems promising, even for well-established ecotourist lodges

No full textDifferences in male and female athletes and their perceptions of an ideal coach with respect to locus of control, competitiveness, goal-orientation and win-orientation
No full textPlan BThe current study examined differences between male and female athletes and their perceptions of an ideal coach. The study focused on internal vs. external locus of control, competitiveness, goal-orientation and win-orientation as a basis to determine possible differences in an ideal coach. An paired-samples t-test was run to test the similar-to-me effect that states that people will choose a leader or manager like themselves. 104 female and 98 male athletes participated in the study from track and field, baseball, softball and basketball. Results indicated that men preferred a more internal locus, competitive and win-oriented coach than women did. Analysis of the self-reports of the athletes reflected these same findings with men scoring significantly higher on internal locus of control, competitiveness and win-orientation. Analysis of the similar-to-me effect indicated that the athletes did not prefer a coach that is similar to themselves. Each variable in this analysis was significantly different at the .001 level from the ideal coach scale to the self-report scale. Findings thus indicate that men and women will prefer different coaches, but will not choose that ideal coach according to their own personality
Establishing High-Fidelity Entanglement in Quantum Repeater Chains
No full textEntanglement is crucial for many applications such as quantum computing, quantum sensing, and quantum communication. Establishment of entanglement between remote nodes, referred to as remote entanglement establishment (REE), is a key element of the quantum internet. This paper develops a theoretical framework for establishing high-fidelity entanglement between two remote nodes of a quantum repeater chain via entanglement generation, distillation, and swapping operations. In particular, an upper bound on the optimal REE rate under minimum fidelity requirements is established, and an REE policy that achieves such a bound asymptotically is presented. Results in this paper provide guidelines for protocol design in the quantum internet

No full textSoft information for localization-of-things
No full textLocation awareness is vital for emerging Internetof-
Things applications and opens a new era for Localizationof-
Things. This paper first reviews the classical localization
techniques based on single-value metrics, such as range and
angle estimates, and on fixed measurement models, such as
Gaussian distributions with mean equal to the true value of the
metric. Then, it presents a new localization approach based
on soft information (SI) extracted from intra- and inter-node
measurements, as well as from contextual data. In particular,
efficient techniques for learning and fusing different kinds of SI
are described. Case studies are presented for two scenarios in
which sensing measurements are based on: 1) noisy features
and non-line-of-sight detector outputs and 2) IEEE 802.15.4a
standard. The results show that SI-based localization is highly
efficient, can significantly outperform classical techniques, and
provides robustness to harsh propagation conditions.RYC-2016-1938
The win odds: statistical inference and regression
No full textGeneralized pairwise comparisons and win statistics (i.e., win ratio, win odds and net benefit) are advantageous in analyzing and interpreting a composite of multiple outcomes in clinical trials. An important limitation of these statistics is their inability to adjust for covariates other than by stratified analysis. Because the win ratio does not account for ties, the win odds, a modification that includes ties, has attracted attention. We review and combine information on the win odds to articulate the statistical inferences for the win odds. We also show alternative variance estimators based on the exact permutation and bootstrap as well as statistical inference via the probabilistic index. Finally, we extend multiple-covariate regression probabilistic index models to the win odds with a univariate outcome. As an illustration we apply the regression models to the data in the CHARM trial.The author(s) reported there is no funding associated with the work featured in this article
Nobel win: spotlight on the attrition of women in science
No full textKatalin Karikó’s joint win of this year’s Nobel Prize in Physiology or Medicine helps to redress the history of gender bias in Nobel awards (see Nature 622, 228–229; 2023). Yet her achievement is not so much a win for female researchers as a warning of how much is being lost through the continued attrition of women in science
Dematerialisation of consumption: a win-win strategy?
No full textA dematerialisation of the economy can provide a crucial contribution toward sustainable devel-opment. It can take place in the production sphere through technological change or in the con-sumption sphere through altered consumer behaviour. This paper focuses on the second case, a shift of expenditure from material consumption (e.g. manufactured products) to non-material consumption (e.g. services). Since all production requires material, an input-output model is used to account for indirect material use. The model features post-Keynesian macroeconomic founda-tions, which make it possible to study the effects of altered consumption patterns on total con-sumption, output, and income distribution. The empirical application for the case of Germany shows that a dematerialisation of consumption might be considered a win-win strategy from an ecological and economic viewpoint. However, its effects on the distribution of income and inter-national trade may be problematic.Sustainable consumption, input-output model, social sustainability, income distribution
