Consumer responses were examined in an incomplete factorial design where Australian consumers evaluated 216 beef samples derived from 18 cattle killed in Australia and Korean consumers evaluated 216 samples from the same 18 cattle, plus 216 similar samples from 18 Korean cattle. Samples of the Mm. triceps brachii, longissimus dorsi and semimembranosus were cooked using grill and Korean barbeque methods. Each sample was sensory tested by 10 consumers, who scored it for tenderness, juiciness, like flavour, and overall liking. Consumers then graded each sample as either unsatisfactory (2 star), good every day (3 star), better than every day (4 star), or premium (5 star) quality. For those samples assessed by both Australian and Korean consumers, the Korean consumers graded a higher proportion of samples ‘unsatisfactory’ and a lower proportion of samples ‘premium’ grade product than Australian consumers. Using a composite meat quality score (MQ4) to predict grade, a discriminant analysis showed that the Korean consumers had boundary cut-offs for the lower grades, which were ~4–10 palatability units higher than the Australian consumers. Analysis of the residuals between actual and predicted palatability scores showed that the Meat Standards Australia (MSA) grading model produced relatively unbiased estimates within ±2 MQ4 units for the different consumer groups, muscle and carcass suspension treatments, with the exception of the M. semimembranosus samples. Implications of the results for both Korean and Australian beef markets through the use of an empirical grading model to predict palatability are discussed.

Abstract Background Accurate de novo genome assembly has become reality with the advancements in sequencing technology. With the ever-increasing number of de novo genome assembly tools, assessing the quality of assemblies has become of great importance in genome research. Although many quality metrics have been proposed and software tools for calculating those metrics have been developed, the existing tools do not produce a unified measure to reflect the overall quality of an assembly. Results To address this issue, we developed the de novo Assembly Quality Evaluation Tool (dnAQET) that generates a unified metric for benchmarking the quality assessment of assemblies. Our framework first calculates individual quality scores for the scaffolds/contigs of an assembly by aligning them to a reference genome. Next, it computes a quality score for the assembly using its overall reference genome coverage, the quality score distribution of its scaffolds and the redundancy identified in it. Using synthetic assemblies randomly generated from the latest human genome build, various builds of the reference genomes for five organisms and six de novo assemblies for sample NA24385, we tested dnAQET to assess its capability for benchmarking quality evaluation of genome assemblies. For synthetic data, our quality score increased with decreasing number of misassemblies and redundancy and increasing average contig length and coverage, as expected. For genome builds, dnAQET quality score calculated for a more recent reference genome was better than the score for an older version. To compare with some of the most frequently used measures, 13 other quality measures were calculated. The quality score from dnAQET was found to be better than all other measures in terms of consistency with the known quality of the reference genomes, indicating that dnAQET is reliable for benchmarking quality assessment of de novo genome assemblies. Conclusions The dnAQET is a scalable framework designed to evaluate a de novo genome assembly based on the aggregated quality of its scaffolds (or contigs). Our results demonstrated that dnAQET quality score is reliable for benchmarking quality assessment of genome assemblies. The dnQAET can help researchers to identify the most suitable assembly tools and to select high quality assemblies generated.

In the context of Poisson sampling, numerous adjustments to classical estimators have been proposed that are intended to compensate for inflated variance due to random sample size. However, such adjustments have never been applied to extensive forest inventories. This work investigates the performances of four estimators for the timber volume in one-phase two-stage forest inventories, where trees in the first stage are selected, at the plot level, by concentric circles or angle-count methods and a subset thereof are selected by Poisson sampling for further measurements to get a better estimation. The original two-stage estimator is the sum of two components: the first is the mean of Horwitz–Thompson estimators using simple volume approximations, based on diameter and species alone, of all first-stage trees in each inventory plot, and the second is the mean of Horwitz–Thompson estimators based on the differences between the simple volume approximations and refined volume determinations based on further diameter and height measurements on the second-stage trees within each inventory plot. This two-stage estimator is particularly useful because it provides unbiased estimates even if the simple prediction model is not correct, which is particularly important for small area estimation. The other three estimators rely on adjustments of the second component of the original estimator that are adapted from estimators proposed in the literature by L.R. Grosenbaugh and C.-E. Särndal. It turns out that these adjustments introduce a negligible bias and that the original simple estimator performs just as well or even better than the new estimators with respect to the variance.

Abstract Coda-duration τ at 42 of the stations in the U.S. Geological Survey's central California seismic network (CALNET) for earthquakes in five source regions of central California—the Parkfield and San Juan Bautista sections of the San Andreas fault, the Sargent fault, the Coyote Lake section of the Calaveras fault, and the Livermore area—are used to obtain empirical formulas relating local magnitude ML and seismic moment M0 to τ and epicentral distance Δ. Models with log2 τ fit the data better than those assuming a log τ dependence. For 55 earthquakes with 1.1. ≦ ML ≦ 5.3, ML = 0.92 + 0.607 (±0.005)log2 τ + 0.00268(± 0.00012)Δ. These ML assume a Wood-Anderson seismograph magnification of 2800; 0.15 should be subtracted from these ML for continuity with magnitudes obtained from or calibrated against typical (magnification ∼ 2000) Wood-Anderson seismographs. For 53 earthquakes with 18.4 ≦ log M0 ≦ 22.3, log M0 = 17.97 + 0.719(± 0.0007)log2 τ + 0.00319(±0.00013)Δ. These relations provide unbiased estimates of ML for 1.5 ≲ ML ≲ 5.3 and 19 ≲ log M0 ≲ 22.3. Station corrections can significantly improve the accuracy and precision of ML and log M0 estimates, particularly if τ from a small number of stations are used. Regional variations in station corrections reflect an increase in coda duration toward the south within the CALNET.

Top height is one of the most useful variables provided by sample plot measurements conducted during forest inventory programs. Combined with tree age, it allows the determination of site index, a common measure of forest site productivity. Unfortunately, there are cases where the number of site trees is suboptimal; this potential problem can lead to imprecise estimates of top height and site index. We approached this problem using ratio estimation techniques and incomplete data sets from forest inventory plots in Québec. We tested different combinations of suboptimal sampling of site trees to estimate top height based on their diameters, using only 2 or 3 site trees per 0.04-ha plot, instead of 4. The results show that suboptimal sampling of site trees should not be conducted randomly, and that some combinations consistently performed better than others. Also, some combinations never outperformed others and should be avoided when estimating top height of some important tree species in Québec using suboptimal sampling of site trees. Finally, for the best combinations, we concluded that the ratio estimation technique generally provided precise and unbiased estimates of top height. Key words: top height, site index, site trees, ratio estimation, forest inventory

The present research demonstrates how consumer responses to negative and positive offers are influenced by whether the administering marketing agent is an Artificial Intelligence (AI) or a human. In the case of a product or service offer that is worse than expected, consumers respond better when dealing with an AI agent in the form of increased purchase likelihood and satisfaction. In contrast, for a better than expected offer, consumers respond more positively to a human agent. We demonstrate that AI agents, in comparison to human agents, are perceived to have weaker intentions when administering offers, which accounts for this effect. That is, consumers infer that AI agents lack selfish intentions in the case of an offer that favors the agent and lack benevolent intentions in the case of an offer that favors the customer, thereby dampening the extremity of consumer responses. Moreover, we demonstrate a moderating effect such that marketers may anthropomorphize AI agents to strengthen perceived intentions, providing an avenue to receive due credit from consumers when providing a better offer and mitigate blame when providing a worse offer. Potential ethical concerns with the use of AI to bypass consumer resistance to negative offers are discussed.

Background: A high rate of cardiac arrest requires high-quality CPR. A valuable CPR rescuer has lower success than two or more rescuers, especially with the use of BVM. There is a complexity encountered with lateral CPR position as a commonly used position, which is the difficulty of position movement from compression to ventilation. On the other hand, Over the Head CPR position is used as an alternative position, which is considered more effective than a lateral position. It is also considered to be able to overcome the obstacles found in CPR with a single rescuer using BVM ventilation in the lateral position so that study is required to compare the quality of CPR between the two CPR positions.Technique: The quality of CPR between Over the Head position CPR and Lateral position CPR is compared. The technique testing was carried out on 24 students using a mannequin. CPR quality components include compression ratios: ventilation, speed, depth, hand placement, chest recoil, and the amount of time of chest compression interruption were observed strictly. The overall CPR quality score, particularly in terms of compression speed and the minimum interruption time of chest compression on Over the Head position, is better than lateral position CPR.Conclusion: Over the Head position, CPR significantly produces a better quality of CPR than Lateral position CPR.

Abstract We investigated the effects of feeding beet pulp (BP) instead of corn flake (CF) on growth performance, beef quality, ruminal fermentation, and blood parameters in Korean cattle steers. Eighteen Korean cattle steers (body weight, 732 ± 12.6 kg; age, 31.2 ± 0.16 months) were divided into the CF and BP groups. The approximately 92% of dry matter of the requirement was offered as a concentrate portion, and the 8% was offered as an oat straw. The 85% of concentrate portion was provided by the pelleted basal concentrate, and the remaining 15% with CF or BP for 12 weeks. Average daily gain, feed efficiency, and carcass traits were not affected by feeding BP. The proportion of ruminal iso-butyrate (P = 0.004), iso-valerate (P = 0.001), and valerate (P = 0.01) were lower in the BP group compared to the CF group. Blood glucose (P = 0.06) and non-esterified fatty acids (P = 0.09) concentrations tended to be higher in the BP group than in the CF group. The results suggest that BP could be a good energy source without affecting the growth performance and beef quality in Korean cattle steers.

The quality characteristic of High Rib (HR), Striploin (SL), Brisket (BK) and Rump (RP) from Songjiang cattle was investigated. The water content, crude protein, intramuscular fat (IMF), color, shear force, pH, cooking loss and sensory evaluation of samples were analyzed. The results showed that, HR sample had the highest (P < 0.05) IMF and RP sample had the highest (P < 0.05) water content. Although crude protein contents among different of samples had significant difference (P < 0.05), its difference was not large as IMF and water content. Cooking loss and hardness value of HR were both lower than other cuts, whereas a* values was not the highest one (P < 0.05). Hardness and cooking loss were both lowest (P < 0.05) in SL, and highest in RP and BK, respectively. The results demonstrated that quality of HR and SL was better than other cuts, and IMF was the key factor that induced the beef quality difference.
