Effects of different methionine sources on growth performance, meat yield and blood characteristics in broiler chickens

ABSTRACT Three graded levels of MHA (methionine hydroxyl analogue) added into the broilers’ diets were based on the assumption that the relative bioavailability of MHA sources to DL-methionine (DLM) on a molar basis was 100%, 90% or 80% to meet the requirement of total sulphur amino acids. DLM was used as the reference control group. Live body weight at 21 and 35 days was retarded (p < 0.05) in chicks fed a diet containing 100% equivalent MHA-FA (methionine hydroxyl analogue free acid) across dietary treatments. Chicks fed the diet containing MHA-Ca vs. MHA-FA grew faster at 35 days (p < 0.05). Chicks consumed least (p < 0.05) when 100% equivalent MHA-FA was added during 1–21 days. FCR was enhanced in MHA-Ca (methionine hydroxyl analogue calcium salt) vs. MHA-FA at all days measured. MHA effect on mortality, being higher (p < 0.05) in chicks on MHA-FA vs. MHA-Ca, was noted. Serum concentration of total cholesterol was lowest (p < 0.05) in chicks fed on DLM-added diet, but highest (p < 0.05) in those fed 100% equivalent MHA-Ca. Serum concentration of immunoglobulin A was low (p < 0.05) in chicks fed on 100% or 80% equivalent MHA-Ca compared with the rest of treatments. Collectively, MHA-Ca performed better than MHA-FA as to performance traits.
Dynamic load balancing algorithm based on HEVC tiles for just-in-time video encoding for heterogeneous architectures

ABSTRACT This paper proposes a novel algorithm for dynamic tile partitioning to achieve the optimal workload balance for parallel processing architectures in just-in-time HEVC encoding. Tile boundaries are dynamically shifted depending on the tile cost, a value that denotes predicted computational complexity of a single tile in a frame. The overall cost of a tile is determined as a combination of costs of three computationally most expensive and resource-hungry operations in HEVC encoding: prediction, transformation, and entropy coding. The algorithm aims at exploiting different types of processing architectures, from homogeneous multicore CPU architectures to heterogeneous architectures in the actual conditions in which streaming servers operate. The experimental results show that the proposed algorithm outperforms uniform tiling, by up to 5.5% in processing time, while maintaining the same video quality and bitrate. Compared to the state-of-the-art algorithms, the proposed algorithm achieves up to 8.85% speedup depending on the number of videos that are being encoded concurrently on a video streaming server.
Detailed alluvial fan geomorphology in a high-arctic periglacial environment, Svalbard: application of unmanned aerial vehicle (UAV) surveys

ABSTRACT A 1:850 detailed map of the geomorphology of the Dynamisk Creek alluvial fan on Svalbard was produced based on very high-resolution data collected using an unmanned aerial vehicle (UAV) in 2014. The map documents features within the surface of the fan (0.35 km2), emphasizing their relative temporal activity. Fluvial flows were the most important geomorphological processes responsible for aggradation and modification of the fan surface. However, at present most of the fan area is inactive (about 75% of the whole fan surface) and stabilized by vegetation and mosses. Furthermore, in some places, niveo-aeolian (6% of the fan surface) and snow avalanches (1.5% of the fan surface) deposits have been noticed. In addition to the map, detailed morphometric characteristics of the fan and its catchment are also provided. The presented work illustrates the enormous usefulness of small UAVs for the study of fan surfaces in periglacial environments.
Sentiment disagreement and bitcoin price fluctuations: a psycholinguistic approach

ABSTRACT We investigate the extent to which Bitcoin price fluctuations are associated with investors’ sentiment disagreement. We employ three textual sentiment analysis techniques: 1) a Python library offered by the Computational Linguistics and Psycholinguistics Research Center; 2) Loughran and McDonald’s (2011) dictionary; and 3) semantic orientation by the point-wise mutual information method. The results show that investors’ attention and sentiment disagreement induce extremely high volatility and jumps in Bitcoin prices. These findings complement existing studies on how investors’ sentiment manifests in asset prices.
Investigation of control of power flow by using phase shifting transformers: Turkey case study

Transmission systems are needed to be upgraded based on expected/unexpected load growth factor by years. However, it is not so easy to install and upgrade the transmission system, which requires transmission planning calculation ahead of time. Traditionally, transmission companies built extra transmission lines to meet that load growth, but it is not easy and cost-effective to upgrade the system every time loads increase. Some unexpected load growth may occur for some load points that is not in the part of planning calculation. For those situations, the transmission system may face serious congestion problems. Transmission companies have been looking for a way to control power flow rather than building extra electricity capacity. With the development of technology, more complex and integrated flexible alternating current transmission system technologies that can control power flows by changing the voltage amplitude, the angle, and the impedance of the transmission line are now widely used. Phase-shifting transformer (PST) is one of the most widely used devices that can be used for controlling power flow. PST can vary the amount or direction of the active power flow by injecting voltage at different phases into the transmission line on which PSTs are installed. In this study, possible location case studies of PST in the Turkish transmission network will be investigated. Static analyses will be performed using the PSS/E and Python programs. The maximum and minimum production status of distributed wind power plants will be analyzed comparatively in the energy corridor with PST. Capacity improvement and power flow dispatch from each case study with and without PST will be compared. Finally, we propose a mathematical model to suitably determine the angle of PST in order to minimize real power losses that are caused by PST and provide N-1 security.
Validation of Anisotropic Electron Fluid Closure Through In Situ Spacecraft Observations of Magnetic Reconnection

A valid fluid model for electrons in collisionless space plasmas is desirable for understanding the structure and evolution of magnetic reconnection geometries. Additionally, such a fluid model would be useful for the simulation of systems too large to be tractable in a fully kinetic model. Using Magnetospheric Multiscale spacecraft observations, we provide direct confirmation of the Lê et al., 2009 (https://doi.org/10.1103/PhysRevLett.102.085001) equations of state for the electron pressure tensor during guide field reconnection and demonstrate how the closure can be applied in efficient numerical simulation, yielding new physical insight to the electron heating problem. Furthermore, we use the Lê et al., 2009 equations of state to predict a scaling of electron heating in the exhaust comparable to the available observational data.
The Role of Gender in Artisanal Fisheries of the Tono Reservoir

The 1,860 ha Tono reservoir is the largest source of water for irrigation and freshwater fisheries production in the Upper East Region of Ghana. The current status of the fisheries was investigated in this study, with emphasis on the role of gender. The reservoir’s fisheries have made a significant contribution to food security and livelihoods. The artisanal fisheries produce an estimated 61.2 metric tons of fish annually and offer employment and income for not less than 480 indigenous households. Participation in the fisheries value chain during the study was gender biased: the ratio of males to females was 104 to 376. The men do the fishing (actual extraction) and mending of the fishing gears, while the women traditionally dominate the downstream post-harvest enterprises. More importantly the women command a considerable influence on the fisheries exploitation as financiers or employers of majority of the fishers.
Do hospitals with electronic health records have lower costs? A systematic review and meta-analysis

ABSTRACT The electronic health record (EHR) recently emerged as a new tool for delivering care to patients in hospitals. Cost savings due to EHR adoption were projected from reduced length of stays from streamlining processes, fewer preventable errors due to clinical decision support, and a general increase in the efficiency of care delivery. I conducted a systematic review and meta-analysis of quantitative research that evaluated the relationship between EHRs and hospital costs. I find hospitals with EHRs with basic capabilities were found to have 12% lower average costs than comparable hospitals, whereas hospitals with more advanced EHRs did not have significantly lower costs. These results may allude to marginal declines in the cost-effectiveness of advanced EHR capabilities.
The Role of Just in Time, Total Quality Management, and Supply Chain Management toward Better Operational Performance

The medical sector has entered an epoch of rapid innovation and strengthened competition that demands more creativity. That rapidly changing environment demand more flexibility for the operations. Although, various studies are available on the effects of multiple approaches on operational flexibility still JIT, TQM, and SCM never have been verified in the same study. This is empirically varification, a questionnaire has been distributed by convenience sampling in the medical sector of Jordan. Total 318 responses received and SPSS have been applied for multiple regression analysis. It has found that all three approaches have positive effects on operational flexibility but very minor even no approach has significant effects. This study is unique because it applies three diversified approaches in the same study and findings are unique. It is recommended for all managers of a medical sector that JIT, TQM, and SCM are not beneficial for operational flexibility for developing countries due to lack of resources, technology, and education. This study will help the researches that more studies need to verify for Jordan hospitals. Moreover, future studies can be done to identify the reasons behind these unique findings.
On the Optimality of Financial Repression

When is financial repression—namely, policies that force banks to hold government debt—optimal? With commitment, such policies are never optimal because they crowd out banks’ productive investments. Without commitment, they are optimal when governments need to issue unusually large amounts of debt, such as during wartime. In such times, repression allows governments to credibly issue more debt. Repression increases credibility because when banks hold government debt, defaults dilute net worth, reduce investment, and are thus costly ex post. Forcing banks to hold debt endogenously increases these ex post costs but has ex ante costs because doing so crowds out investments.
Do salespeople matter in competitive tenders?

Abstract Organizational buyers are increasingly employing competitive tenders with objective buying criteria to mitigate the influence of personal relationships with suppliers and reduce the overall cost of buying. This paper investigates the role of salespeople’s relationships with buyers (i.e., purchasing managers) and how they affect supplier selection in such contexts. Drawing on data from 428 tenders across different buying organizations, this study shows that the quality of the salesperson’s relationship with the buyer influences the buyer’s evaluation of the tender proposal, which, in turn, affects supplier selection. Thus, the results support an indirect effect of salesperson relationship on supplier selection even in a tender context. In addition, the results indicate that the effect of a salesperson’s relationship on buyer’s proposal evaluation is contingent on the comprehensibility of suppliers’ proposals and buyer’s product knowledge. These results have significant theoretical and managerial implications for both buyers and suppliers in business-to-business (B2B) tender contexts.
Revealing The Colourful Side of Birds: Spatial Distribution of Conspicuous Plumage Colours on The Body of Australian Birds

In many species of birds, different body parts often display very different colours. This spatial distribution of coloured plumage patches may be determined by the balance between being cryptic to predators, and conspicuous to intended receivers. If this is the case, ventral and anterior body parts in birds–which are less visible to predators but more prominent to conspecifics– should present more conspicuous and sexually dichromatic plumage colours. Here I test these predictions using reflectance spectrometric measurements of standardised plumage patches across males and females for nearly an entire avifauna (Australian landbirds, N = 538 species). My data show that, as predicted, conspicuous colours are mainly located near the head, while the plumage of the back is the most cryptic. However, there is considerable variation across species, and this makes position on the body a relatively modest predictor of plumage elaboration (R2 = 0.15-0.19). One clear exception to this pattern is the conspicuous rump coloration. In many species, this patch can be concealed by wings, and therefore exposed only when necessary. In addition, conspicuous rump coloration could deflect or confuse predators in case of attack. Finally, patterns for sexual dichromatism were much weaker (R2 = 0.02), whereby wing and tail showed lower levels of dichromatism than the rest of the body.
The Relationship Between Malaysian Supermarket In-Store Shopping Experiences and Positive Word-of-Mouth

Attitudinal loyalty such as customers’ willingness to spread positive words of mouth has received less attention compared to behavioural loyalty (e.g., reptronage intention) in retail studies, particularly in the context of supermarket. It is argued that supermarket consumers should be willingly share positive words of mouth when they are satisfied. The effect of Malaysian supermarket in-store experiences (convenience, merchandise value, internal shop environment, interaction with staff, merchandise variety, presence interaction with other customers, in-shop emotion) on customer satisfaction and mediating effect of customer satisfaction on the relationship between in-store experiences and positive WoM were examined. The results show significant relationship between customer satisfaction and willingness to spread positive WoM. Convenience and in store emotion have significant relationships with customer satisfaction, while the other in-store experiences have no significant effects on satisfaction. Customer satisfaction played mediation roles between the relationships between convenience, merchandise variety, interaction with staff and in store emotion with positive WoM. The findings provide useful insights to Malaysian supermarket retailers in understanding their target markets to encourage more positive WoM.
Genetic diversity of Symplocos paniculata of Hunan province revealed by inter-simple sequence repeat (ISSR)

The natural populations’ genetic diversity of Symplocos paniculata in Hunan province was evaluated by using Intersimple sequence repeat (ISSR) markers. In all 122 loci were identified in 149 individual plants of six populations using nine selected ISSR primers (UBC815, UBC817, UBC824, UBC835, UBC845, UBC853, UBC862, UBC873 and UBC879) and 92.2% loci were polymorphic. Nei’s gene diversity (H) and shannon information index (I) were 0.3264 and 0.4873, respectively. The coefficient of gene differentiation (Gst) was 0.5397. Gene flow among populations (Nm) was 0.4763. Analysis of molecular variance (AMOVA) demonstrated that the genetic differentiation among S. paniculata populations was relatively high (p<0.001). The among-population component accounted for 51.1% of the total variation, while the within-population component accounted for 49.8%. Six populations were clustered into three groups by the unweighted pair-group method arithmetic average (UPGMA). The results showed that populations of Da Wei Shan A (DWSA), Da Wei Shan B (DWSB) and Xiang Xi Long Shan (XXLS) were in the first group, populations of Yue Yang Jun Shan (YYJS) and Yong Zhou Dao Xian (YZDX) were in another group, and Heng Yang Hen Shan (HYHS) population separated from all the populations in the dendrogram. The cluster results were mutually related to the geographical elevation, but not to geographical distribution.
Immediate loading of Brånemark System® TiUniteTM and turned-surface implants in the anterior mandible

The purpose of the present study was to compare the treatment outcome of TiUniteand machined-surfaced Brånemark System implants when applying immediate loading of cross-arch designed FPDs in the anterior mandible. Fifteen patients with edentulous mandibles participated in the study. In one half of the jaw, between the exit of the nerve-vessel bundle and the midline, one type of implants was placed and in the remaining half the other type. The implants were loaded the day of surgery via a fixed, temporary supraconstruction (Schnitman et al. 1997). Ten days later the permanent one was screw retained to the implant pillars. The present 18-month clinical trial failed to demonstrate any differences regarding healing and cumulative success rate of an an-oxidized implant surface (TiUnite) and a machined (turned) one when implants in the anterior mandible were exposed to functional load within 24 hours after installation. In conclusion, a high predictability regarding the treatment outcome for immediately loaded Brånemark implants in the anterior mandible was observed. Furthermore, no difference between the traditional turned and the an-oxidized implant surface (TiUnite) could be observed. However, it has to be stressed that all implants (irrespective of surface) were placed in the
Role of transnational and national education policies in realisation of critical thinking: the cases of Sweden and Kosovo

Abstract Against the backdrop of the push from the European Commission and the Organisation for Economic Cooperation and Development for competence-based curricula, this article problematises the complexity of developing twenty-first century skills, such as critical thinking, by addressing the role transnational and national policy contexts play in realising critical thinking in the national contexts of Sweden and Kosovo. The article distinguishes between policy-critical thinking and civic-critical thinking. Relying on analyses of curriculum and policy documents, it is concluded that while in the Swedish context critical thinking competence (or ability) seems to be much more implicit than explicit, in Kosovo, the national curriculum makes explicit references to thinking competences as a form of policy-critical thinking and civic competencies as a form of civic-critical thinking. Thus, students in both contexts have opportunities to develop critical thinking skills. Furthermore, Sweden emerges as a divergent case and Kosovo as a convergent case with regard to transnational policy flow research paradigms.
PENGUNGKAPAN EMISI KARBON SEBAGAI MEKANISME PENINGKATAN KINERJA UNTUK MENCIPTAKAN NILAI PERUSAHAAN

The purpose of this research was to investigate the effect of carbon emissions disclosure on financial performance, operational performance and cost of equity, the influence of financial performance, operational performance, and cost of equity on firm value, and to investigate the effect of carbon emissions disclosure on firm value mediated by financial performance, operational performance, and cost of equity. Population used is the whole company public listed in Indonesia Stock Exchange period 2013- 2015. Number of samples are 86 firms each year, was selected by purposive sampling method and using secondary data, i.e. the annual report. The analytical method used is path analysis and hypothesis mediation analysed by using Sobel test. The result of analysis show that carbon emissions disclosure have positive and significant effect on financial performance, operational performance and cost of equity. While financial performancebhave positive but not significant effect on firm value, operational performance have positive and significant effect onfirm value, and cost of equityhave negative and significant effect on firm value. This research also shows that the operational performance and cost of equity plays a role in mediating carbon emissions disclosure on firm value, while financial performance do not mediate the effect of carbon emissions disclosure on firm value. The implication is the firms should pay more attention to the company's relationship with the surrounding environment so that the company's image can be improved because the firm’s sustainability are not only determined by the level of profitability, but also they have to combine economic performance, the concentration of social justice, and responsibility towards environmental sustainability. Keywords: carbon emissions disclosure, financial performance, operational performance, cost of equity and firm value
Predicting future distributions of lanternfish, a significant ecological resource within the Southern Ocean

Lanternfish (Myctophidae) are one of the most abundant and ecologically important families of pelagic teleosts, yet how these species will respond to climate change is unclear, especially within polar regions. The aim of this study was to predict the impact of climate change on the distribution of Southern Ocean lanternfish and to relate these predicted responses to species traits.
Sensitivity and specificity of the Vectraplex electrocardiogram system with a cardiac electric biomarker in the diagnosis of ST-elevation myocardial infarction

Abstract ST-elevation myocardial infarction (STEMI) is a clinical diagnosis based on a compatible history and characteristic electrocardiographic changes. In the current era, STEMI is treated emergently with angiography, leading to percutaneous coronary intervention. However, false-positive electrocardiograms (ECGs) occur, resulting in unnecessary emergent catheterizations. We hypothesized that the Vectraplex cardiac electrical biomarker (CEB) would increase the specificity for the diagnosis of STEMI. We studied 50 patients who were identified by standard of care (clinical history, physical exam, and 12-lead ECG) as suspected to have STEMI and tested the sensitivity and specificity of the Vectraplex ECG system. Using the final clinical diagnosis (based on history, ECGs, troponin values, and angiographic findings) as the gold standard, we found the CEB value to be quite dynamic, with a reasonable sensitivity and a good positive predictive value but generally poor specificity and negative predictive value. It offered only a 20% improvement compared to 50-50 performance on receiver operator curves.
Crowded Trades and Tail Risk

Hedge fund positions are an important component of crowded trades. These vehicles are particularly active, take highly concentrated positions, and utilize leverage and short sales. Using a database of hedge fund holdings, we measure the degree of security-level crowdedness. The difference between the average returns on portfolios sorted by high versus low crowdedness portfolios is sizable, and the variation in the realized portfolio returns is distinct from other traditional risk factors. Further, hedge fund exposures to crowdedness are often significant, and they help to explain downside “tail risk,” as funds with higher exposures experience relatively larger drawdowns during periods of industry distress.
