Research on The Influence Mechanism of Virtual Brand Community Participation on Users' Competitive Brand Attitude

This study explores the influence of virtual brand community participation on consumers' attitude towards competitive brands. This study took mobile phone industry community (huawei, xiaomi, apple) as the research object. The analysis results show that the participation of virtual brand community makes members perceive benefits. In addition, hedonic, social and learning benefits are the main factors forming community commitment, especially hedonic benefits. When members have community commitments,they increase negative perceptions of other competing brands.In addition, UGC level negatively moderates the relationship between community participation and perceived benefits of virtual brands. Finally, this study provides some effective Suggestions for enterprises to improve the community experience.
Scientific Merits and Analytical Challenges of Tree‐Ring Densitometry

X‐ray microdensitometry on annually resolved tree‐ring samples has gained an exceptional position in last‐millennium paleoclimatology through the maximum latewood density (MXD) parameter, but also increasingly through other density parameters. For 50 years, X‐ray based measurement techniques have been the de facto standard. However, studies report offsets in the mean levels for MXD measurements derived from different laboratories, indicating challenges of accuracy and precision. Moreover, reflected visible light‐based techniques are becoming increasingly popular, and wood anatomical techniques are emerging as a potentially powerful pathway to extract density information at the highest resolution. Here we review the current understanding and merits of wood density for tree‐ring research, associated microdensitometric techniques, and analytical measurement challenges. The review is further complemented with a careful comparison of new measurements derived at 17 laboratories, using several different techniques. The new experiment allowed us to corroborate and refresh “long‐standing wisdom” but also provide new insights. Key outcomes include (i) a demonstration of the need for mass/volume‐based recalibration to accurately estimate average ring density; (ii) a substantiation of systematic differences in MXD measurements that cautions for great care when combining density data sets for climate reconstructions; and (iii) insights into the relevance of analytical measurement resolution in signals derived from tree‐ring density data. Finally, we provide recommendations expected to facilitate futureinter‐comparability and interpretations for global change research.
Screening and Selection of Elite Plant Growth Promoting Rhizobacteria (PGPR) For Suppression of Rhizoctonia solani and Enhancement of Rice Seedling Vigor

Sheath blight (ShB) of rice, caused by Rhizoctonia solani is an economically significant disease throughout the world. Management of ShB using plant growth-promoting rhizobacteria (PGPR) is an ecologically-friendly and viable alternative to current use of chemical fungicides. To select efficacious PGPR strains, approximately 70 isolates were screened for their antagonistic activity on vegetative growth and sclerotial germination of R. solani using dual in-vitro antibiosis assays. The strains were also screened for enhancement of rice seedling emergence under in vitro conditions. Ten PGPR strains were screened in each assay. In dual culture assays, mycelial plug of actively growing culture of R. solani was grown in Petri dishes containing 10% TSA and the PGPR strain was streak inoculated at 2 CM away on opposite sides. Plates were incubated at 250 C for 5 days and observations on mycelial inhibition of R. solani by PGPR were taken. Surface sterilized sclerotia of R. solani were treated with liquid PGPR inoculum for 24 h and later plated onto Petri dishes containing PDA. There were five replications for each PGPR strain. Sclerotial germination and growth inhibition were observed after incubating for 5 days at 250 C. To study the effect of PGPR strains on rice seedling vigor, surface sterilized rice seeds of Cv. Cocodrie in bacterial suspensions at a concentration of 4 x 108 cfu/ml for 24 h. The seeds were later dried and incubated for 7 days. There were 3 replications and 25 seeds for each replication. In vitro antibiosis assays showed that the majority of the strains significantly suppressed the mycelial growth of R. solani compared to the control. Similarly, four out of 70 strains tested significantly suppressed sclerotial germination when the sclerotia were treated with PGPR suspensions. Majority of the strains significantly increased seedling vigor when tested as seed treatments under in vitro conditions. The strains Bacillus amyloliquefaciens AP 219, B. subtilis strains MBI 600 and AP 52 performed the best in these assays.
Shaft Whipping Due to Oil Action in Journal Bearings

Shaft whipping is a form of vibration or whirling developed under certain conditions in shafts running above their critical speeds. The authors have produced this phenomenon with models, and have traced the cause to the action of the oil film in the bearings. They find that the phenomenon when produced in this way does not occur at running speeds lower than about double the critical speed of the rotor. To prevent trouble from this source the authors suggest that very low unit bearing pressures be avoided or that a friction­ damped spring be used. A previous investigation reported in this magazine dealt with a similar phenomenon caused by internal friction of the rotor. The article by A. L. Kimball in this issue details the measurement of the internal friction of shafts, which also has been found to-be a cause of whipping. -EDITOR.
Investigation into the Specifics of the use of STT- RAM and SRAM in Cache Hierarchies

the objective of this paper is to investigate the implementation of different types of cache hierarchies. The most interesting to me being the use of buffers to delay writing data to memory unless it is needed immediately. Another interesting method for optimization was the use of MLC in STT-RAM to further increase the capacity of the cache and hopefully offsetting the disadvantages of STT-RAM to SRAM. This paper also breaks down the exact numbers of energy usage, read/write latency, area overhead, and IPC associated with each type of memory to hopefully give the reader an idea of the challenged that engineers face when having to deal with optimizing cache hierarchies. Keywords— MLCMulti Level cell, STT-RAM-Spin-Transfer Torque Random Access Memory, SRAM-Static Random Access Memory, Non-Volatile memory – memory that doesn’t need power to store bits, Volatile Memory – memory that needs to have power in order to store bits, MTJ – magnetic tunnel junction
A Reinforcement Learning Based Algorithm for Multi-hop Ride-sharing: Model-free Approach

The growth of autonomous vehicles and self driving technology will bring a shift in the way ride hailing platforms plan out their services. In this paper, we propose a novel multi-hop ride-sharing (MHRS) algorithm that uses deep reinforcement learning to learn optimal vehicle dispatch and matching decisions by interacting with the external environment. By allowing customers to transfer between vehicles, i.e
University of Groningen Mental slowness in patients with Parkinson's disease

Introduction: Motor slowness (bradykinesia) is a core feature of Parkinson’s disease (PD). It is often assumed that patients show mental slowness (bradyphrenia) as well; however, evidence for this is debated. The aims of this study were to determine whether PD patients show mental slowness apart from motor slowness and, if this is the case, to what extent this affects their performance on neuropsychological tests of attention, memory, and executive functions (EF). Method: Fifty-five nondemented PD patients and 65 healthy controls were assessed with a simple information-processing task in which reaction and motor times could be separated. In addition, all patients and a second control group (N = 138) were assessed with neuropsychological tests of attention, memory, and EF. Results: While PD patients showed significantly longer reaction times than healthy controls, their motor times were not significantly longer. Reaction and motor times were only moderately correlated and were not related to clinical measures of disease severity. PD patients performed significantly worse on tests of attention and EF, and for the majority of neuropsychological tests 11–51% of the patients showed a clinically impaired performance. Reaction times did not, however, predict patients’ test performance, while motor times were found to have a significant negative influence on tests of attention. Conclusions: PD patients show mental slowness, which can be separated from motor slowness. Neuropsychological test performance is not influenced by mental slowness; however, motor slowness can have a negative impact. When interpreting neuropsychological test performance of PD patients in clinical practice, motor slowness needs to be taken into account.

Web Médica Acreditada Guidelines: Reliability and Quality of Health Information on Spanish-Language Websites

The number of websites providing health information and services on the Internet increases day by day. The quality of these websites is very variable and difficult to assess. There are many self-regulatory initiatives in the English-speaking world to develop quality and ethical standards for health information on the Internet, but few similar Spanish-language initiatives have emerged whilst some studies suggest that quality standards are lower in the Spanish-language sites. A Spanish initiative to improve the quality of these websites would, therefore, seem to be a very important initiative. In Spain, Web Médica Acreditada (WMA) is an initiative to develop quality and ethical standards for health information. The aim of these standards is to improve websites providing such health related-content and services. In this article we present the WMA Guidelines and explain how WMA applies its quality criteria. Quality of Internet health information is essential because it has the potential to benefit or harm a large number of people and it is therefore essential to provide consumers with some tools to aid them in assessing the nature of the information they are accessing and how they should use it without jeopardizing their relationship with their doctor.
Passively Track WiFi Users with an Enhanced Particle Filter using Power-based Ranging

Passive positioning systems produce user location information for thirdparty providers of positioning services. Since the tracked wireless devices do not participate in the positioning process, passive positioning can only rely on simple, measurable radio signal parameters, such as timing or power information. In this work, we provide a passive tracking system for WiFi signals with an enhanced particle filter using fine-grained powerbased ranging. Our proposed particle filter provides an improved likelihood function on observation parameters and is equipped with a modified coordinated turn model to address the challenges in a passive positioning system. The anchor nodes for WiFi signal sniffing and target positioning use software defined radio techniques to extract channel state information to mitigate multipath effects. By combining the enhanced particle filter and a set of enhanced ranging methods, our system can track mobile targets with an accuracy of 1.5m for 50% and 2.3m for 90% in a complex indoor environment. Our proposed particle filter significantly outperforms the typical bootstrap particle filter, extended Kalman filter and trilateration algorithms.
Examining the Financial Attitudes and Behaviors of Y Generation via Structural Equation Modeling

Members of Y generation composed of individuals born between 1980-2000, is a generation that has to work for living. In their lives, technology is one of the most important things. This generation, which does not like to work, loves entertainment and winning, acts aggressive to authority, consumes fast and has dissatisfied manner. Their most important characteristics are freedom, technology and loneliness. One other characteristics of this generation is having much self-confidence. The purpose of this study is to model the financial attitudes and behaviors of Y generation via structural equation modeling. With this purpose a Likert scale type questionnaire, ranging from 1 ‘strongly disagree’ to 5 ‘strongly agree’ is applied to 372 individuals via Computer Assisted Personal Interviewing (CAPI) on Pollyfy application. The data set is analyzed by SPSS and LISREL software. Results of the study indicate that, while the individuals of Y generation consider having an emergency funds a financial attitude, they mentioned that the financial issues do not confuse or depress them as a financial behavior.
Autonomic Nervous System Response to Heat Stress Exposure by Means of Heart Rate Variability

In this study, a heart rate variability (HRV) analysis guided by respiration is conducted to assess changes in autonomic nervous system (ANS) regulation during pronounced heat stress induced by repetitive exposures to dry sauna in 13 young healthy subjects. The spectral power at the low frequency (LF) band [0 . 04 , 0 . 15] Hz and at the high frequency band centered around the mean respiratory rate, estimated from ECG-derived respiration signals, are studied. The mean heart rate (HR), the total power of HRV, and the normalized LF power are also analyzed. Results show that mean HR and normalized LF power increase signiﬁcantly after basal stage, not only during the sauna sessions, but also at the intermediate short rest stages and recovery phase after 30 min. A signiﬁcant reduction in the total power of HRV during all sauna sessions is observed, while an increased power in LF band is shown only during recovery which might be related to improved cardiac function (increased cardiac output and reduced peripheral vascular resistance) after heat exposure. Respiratory rate does not change signiﬁcantly during the protocol but a negative trend at stress stages may indicate a reverse reaction against an over-activation of the sympathetic branch. In conclusion, exposure to heat stress shifts sympathovagal balance of ANS toward sympathetic dominance that increases HR and diminishes
R&D Investments, Technology Spillovers, and Stock Returns*

I demonstrate that R&D investment is crucial for firms to effectively absorb and benefit from potential technology spillovers. In the presence of large spillovers, I find that firms with higher R&D earn significantly higher subsequent equity returns. Importantly, when exposed to large spillovers, higher R&D firms generate more patents (citations) per available spillover and exhibit higher operating performance. I further demonstrate that the complementary relation between R&D and spillovers is most pronounced among low investor attention stocks. My findings suggest that the market appears to undervalue the complementary role of R&D, and that limited investor attention contributes to this undervaluation.

Student Teachers ' Stereotyping and Typification AARE Conference of Aborigines and Australians : Consequences and November , 1990 Implications for the Construction of Aboriginal Identity

This paper investigates pre-service teacher education students' stereotyping and typifying of Aborigines and Australians. This investigation is located in the context of the construction of Aboriginal social identity and in particular the role of the teacher in this social process. The assumption made is that the meanings teachers take into their classrooms re different racial and ethnic groups are fairly clearly represented in the way in which they define, stereotype and typify those respective racial and ethnic groups. Particularly for children, these stereotypes and typifications held by the teacher, by groups of teachers, and school principals, will be important determinants of the child's construction of his social identity(self), his self-respect and his self-esteem. When linked to the data on self, school achievement and life chances the consequences would seem to be significant. In this study a sample of eighty second and fourth semester preservice teacher education students were asked to typify Aborigines and Australians in relation to seventeen traits. Of the ten stereotypes attributed to Aborigines all but one were negative. By contrast of the thirteen stereotypes attributed to Australians only three were negative. It is highly likely that these students, on graduating, will take their theorizing about these categories of people to their classrooms and construct their interactions with their pupils and pupils' parents around these theories. The paper suggests that the difficulties these student teachers will have in constructing positive expectations and interactions with Aboriginal students is considerable and likely to be overwhelming. The context which they enter will provide social, professional and academic interactions which will reinforce the already constructed stereotypes and typifications. This is clearly to the detriment of Aboriginal pupils. The outcomes of this study have important ramifications for the preservice and inservice education of teachers. The stereotypes found to exist and their likely consequences would suggest that there is a need for teacher education programs to confront and respond to the enthnocentric attitudes that many students arrive with and maintain during their programs. The question that emerges is, "How do we break down the stereotypes and typifications student teachers (and teachers) have ? " There would appear to be little in most current teacher education programs that successfully respond to this task.
NUMERICAL COMPARISON OF STEADY DISTURBANCES IN THE WAKE OF PERIODIC BLOW– SUCTION AND ROUGHNESS ELEMENTS

Numerical simulations of the effect of Gӧrtlerlike vortices is investigated for a laminar Mach 8 15 compression corner flow for Reynolds number Re∞,L=3.71×10 based on flat plate length. Two ways of seeding the vortices of various intensity ahead of separation bubble are considered. The first deals with periodic blow– suction with controllable spanwise amplitude of the normal-to-wall mass rate. The second deals with periodic cylindrical roughness elements of various heights. Both ways are compared in terms of flow patterns and surface heat flux.
Interactive Visualizations for Deep Learning

Fig. 1. This SentimentTree visualization shows how word-level sentiments build up over multi-word phrases to produce the overall sentiment associated with a sentence. Leaf nodes represent individual words such as Steven, Solaris, and failure. Non-terminal nodes represent phrases such as glorious failure. The root node represents the full sentence: If Steven Soderbergh’s ‘Solaris’ is a failure it is a glorious failure. Colors encode sentiment ratings given by human subjects, where blue is positive and red is negative. Human raters find the majority of words in this sentence to be neutral with the exceptions of failure being negative and glorious being positive. Sentiment compositionality comes from combining words or phrases to form longer text, but the resulting ratings can take many forms. The phrase glorious failure is rated as negatively as the word failure itself. However, while the two main clauses of this sentence, Steven Soderbergh’s ‘Solaris’ is a failure and it is a glorious failure are both negatively rated, their concatenation suggests an overall positive view about the film Solaris. Our algorithm produces the current state-of-the-art accuracy on sentence-level sentiment predictions.
THE CONTRIBUTION OF LINGUISTICS TO UNDERSTANDING THE FORAGING/FARMING TRANSITION IN NE INDIA

The archaeology of NE India is poorly developed, and in particular there are no direct dates to establish the date or process of the transition from foraging to agriculture. Ethnographic evidence suggests this might be quite late in some regions, with hunting and gathering remaining an important element in subsistence until recently. Linguistic methods can be used to contribute to hypotheses concerning the nature of this process. The paper explores regional linguistic ethnohistory, contributing a new and more accurate map of languages. It then looks at evidence for subsistence, in particular the significance of the mithun and vegetative crops such as taro and the Musaceae. Finally, because the introduction of iron is clearly of great significance and some the published statements concerning linguistic reconstruction are highly misleading it looks at iron terminology.

A simple and rapid molecular detection of Staphylococcus aureus A simple and rapid molecular detection of Staphylococcus aureus strain B using multiplex PCR (P. 13) strain B using multiplex PCR (P. 13)

Background: Staphylococcucs aureus (S. aureus) is one of the most important and pathogenic species from the Staphylococcaceae family. S. aureus is capable of producing several enterotoxins (SEs) that are classified in different groups from A-R. Objective: The present study aimed to set up simple and rapid detection of S. aureus strain B to develop a multiplex polymerase chain reaction (PCR) assay for the identification of genus and strain B of this bacterium. Methods: In this work, after designing specific primers for 23S rRNA and SEB, one step multiplex PCR was carried out and the PCR product analyzed by agarose gel electrophoresis. The specificity of this method was determined using different strains of S. aureus A (SEA), S.aureus C (SEC), Bacillus subtilis , Bacillus cereus , and Listeria monocytogenes . Also, the sensitivity was distinguished by serial dilution of the DNA genome from S. aureus . Results: The PCR product was indicated at 226 and 1,250 bp specific amplified fragments according to amplification of SEB and 23SrRNA, respectively. The sensitivity of this method determined about 2  10 3 CFU/ml and also the results showed that according to specific primers, the PCR is very specific. Conclusion: This multiplex PCR assay can be used as a simple diagnostic test in clinical laboratories for identification of S. aureus .
Multi-PoP Network Slice Deployment: A Feasibility Study

Network slicing is seen as a key enabler for meeting the diverse network service requirements, which stem from the transition to 5G. Furthermore, network slicing provides inherent support for multi-tenancy, enabling network providers to slice their infrastructure and resell it to a large number of tenants. Most existing work on slicing has been focused on certain mechanisms (e.g., slice embedding) and architecture specifications. As such, the performance and scalability with network slice instantiation has not been studied in depth. These aspects are even more critical in the case of slice deployments across multiple Points-of-Presence (PoP), since the various slice components should be stitched together for the end-to-end slice instantiation. In this paper, we present the design and prototype implementation of a network slicing architecture, based on which we perform a feasibility study of network slicing using multiple experimental infrastructures. Our prototype implementation supports all the required functionality for slice instantiation, such as resource discovery, slice embedding, resource provisioning, link setup, and inter-PoP slice segment stitching. Our experimental results corroborate the feasibility of multi-PoP network slicing. We further gain useful insights on slice instantiation performance and scalability.
