Network Forum Investor Sentiment, Sentiment Volatility And Stock Market-- An Empirical Analysis Based on Multivariate GARCH-BEKK Model

Based on the text of posing on the network forum, we establish a set of keyword dictionary to measure the long and short investors' sentiment effectively, then we investigate the mutual relations between investor sentiment and the trading market through a Multivariable BEKK-GARCH model of abnormal long and short investors sentiment, returns and abnormal trading volume. The results show that abnormal sentiment of long investor has a negative impact on the returns and a positive impact on the abnormal trading volume; While abnormal sentiment of short investor has no impact on the return and a negative impact on the abnormal trading volume. Otherwise, there is the negative volatility effect from abnormal sentiment of long investor to returns and abnormal trading volume, the positive volatility effects from abnormal sentiment of short investor to returns, and no volatility effects from abnormal sentiment of short investor to abnormal trading volume. In addition, network forum investor sentiment is a factor affecting the trading market. The analysis of forum information plays a certain role in presenting market risk and improving efficiency in making investment decision.
Assessing the Resilience of ASEAN Banking Systems: the Case of the Philippines

Since the global financial crisis in 2008/09 there has been heightened concern about the resilience of banking systems in Southeast Asia. This paper proposes a methodology that uses a macroprudential perspective to assess the resilience of banking systems in member countries of the Association of Southeast Asian Nations. It then proceeds to apply this methodology to examine the resilience of the Philippine banking system. Data on financial soundness in the Philippine banking system are utilized in a vector autoregression model to study the dynamic relationships that exist among financial and macroeconomic indicators. Using impulse response functions, a simulation of financial ratios in the banking system is conducted by assuming unlikely but plausible stress scenarios to determine whether banking system credit and capital could withstand the impact of such circumstances. In the stress scenarios, the estimated impact of macroeconomic shocks on nonperforming loan and capital adequacy ratios is generally minimal. The results, however, do suggest that the Philippine banking system has some vulnerability to interest rate and stock market shocks. The results of such stress testing provide a better understanding of the level of preparedness required for managing risks in the financial system, especially in the wake of continuing global economic uncertainty.
Survival Analysis - Breast Cancer

Abstract. In this study we used the parametric survival approach to analyze the survival time of African American breast cancer patients. In research about the survival time of patients, the Cox Proportional Hazard model, a semiparametric method, is primarily used, but this approach does not rely on the distributional assumptions. The parametric method is more consistent with a theoretical approach compared to a semi-parametric approach. We observe that the survival time of African American breast cancer patients follows the Weibull Probability Distribution. First, we fitted the model to represent the survival ability of the general population (African American women diagnosed with breast cancer), treating everyone the same. Second, we incorporate other patient-specific covariate factors affecting the survival time to predict lifetime of a particular patient, given that her information is fully known.
Supply Chain Considerations for Electronic Grocery Shopping

The main hypothesis of the dissertation is that "e-grocery with home delivery can be more efficient than supermarket retailing handling a similar volume of sales". The e-grocery business should be seen as an assembly industry producing shopping baskets. Only in this way can the new electronic channel work efficiently. The e-grocery business is usually seen as a supermarket copied into an electronic form; it is seen only as an opportunity to buy products. Instead, the starting point of operational design should be the real needs of a household and take into account the possibility of adding new services for the customers. One of the conclusions of this research is that the operational costs of a distribution centre can be lower than those of a supermarket. Store-based order picking is less expensive than using a specialised distribution centre when turnover is less than one million euros. A turnover of more than 3 million euros means that a dedicated distribution centre appears to be more efficient than store-based picking. However, the distribution centre has to be purpose-built for shopping basket assembly with a reasonably stable workload. A combination of store-based picking and a specialised distribution centre has been introduced as an opportunity to create gradual low-risk growth in the e-grocery business. It seems that efficient home delivery can be achieved even with a moderate market share. Unattended reception is very important for the overall cost structure of the supply chain and enable service models that give flexibility in route planning and optimisation. However, the investments that unattended reception requires should also be taken into account. The cost efficiency of a home delivery service model can be described by the average mileage driven per order, which directly correlates with the number of stops per hour. New efficiency indicators are needed to measure the efficiency of the e-grocery business. Sales per distribution centre and sales per square kilometre are useful indicators when choosing home delivery service models and potential market areas. The most useful factor is sales per square kilometre. The critical sales volume appears to be 200,000 euros per square kilometre per annum. This sales volume can be achieved with 25 four-person households per square kilometre with 90 percent purchase loyalty. E-grocery retailing is a very local business and store-based picking is a good alternative if fast roll-out with a low level of investment is required. A distribution centre-based operation is potentially much more efficient, but it is a slower approach and needs more investment. Whatever service model is chosen, it should first be made to work in a fairly compact geographical area and then copied to new areas.
Location, governance, and strategic determinants of Japanese manufacturing investment in the United States

A firm's decision to manufacture abroad depends on location, governance, and strategic factors. Governance factors are firm‐specific. In spite of this, most empirical studies of foreign direct investment (FDI) have been conducted at the industry level (making it impossible to look at firm‐specific determinants), and only a handful have considered governance, location, and strategic factors simultaneously. This paper is the first large sample study of the determinants of foreign direct investment at the product and firm‐level. It examines the impact of location and governance factors, and of four types of strategic interactions, on a Japanese firm's propensity to manufacture in the U.S. The results support the view that foreign direct investment is explained by location, governance, and strategic variables. Economies of scale and trade barriers encourage Japanese FDI in the U.S. The larger a Japanese firm's R & D expenditures, the greater the probability it will manufacture in the U.S., but this is not the case for advertising expenditures. Some strategic factors are also important: Japanese firms with medium domestic market shares have the highest propensity to invest in the U.S. There is evidence of follow‐the‐leader behavior between firms of rival enterprise groups, but none of ‘exchange‐of‐threat’ between American and Japanese firms. Japanese investors are also attracted by concentrated and high‐growth U.S. industries.
Fat Mobilization in Adipose Tissue Is Promoted by Adipose Triglyceride Lipase

Mobilization of fatty acids from triglyceride stores in adipose tissue requires lipolytic enzymes. Dysfunctional lipolysis affects energy homeostasis and may contribute to the pathogenesis of obesity and insulin resistance. Until now, hormone-sensitive lipase (HSL) was the only enzyme known to hydrolyze triglycerides in mammalian adipose tissue. Here, we report that a second enzyme, adipose triglyceride lipase (ATGL), catalyzes the initial step in triglyceride hydrolysis. It is interesting that ATGL contains a “patatin domain” common to plant acyl-hydrolases. ATGL is highly expressed in adipose tissue of mice and humans. It exhibits high substrate specificity for triacylglycerol and is associated with lipid droplets. Inhibition of ATGL markedly decreases total adipose acyl-hydrolase activity. Thus, ATGL and HSL coordinately catabolize stored triglycerides in adipose tissue of mammals.
Distinguishing Fast and Slow Processes in Accuracy - Response Time Data

We investigate the relation between speed and accuracy within problem solving in its simplest non-trivial form. We consider tests with only two items and code the item responses in two binary variables: one indicating the response accuracy, and one indicating the response speed. Despite being a very basic setup, it enables us to study item pairs stemming from a broad range of domains such as basic arithmetic, first language learning, intelligence-related problems, and chess, with large numbers of observations for every pair of problems under consideration. We carry out a survey over a large number of such item pairs and compare three types of psychometric accuracy-response time models present in the literature: two ‘one-process’ models, the first of which models accuracy and response time as conditionally independent and the second of which models accuracy and response time as conditionally dependent, and a ‘two-process’ model which models accuracy contingent on response time. We find that the data clearly violates the restrictions imposed by both one-process models and requires additional complexity which is parsimoniously provided by the two-process model. We supplement our survey with an analysis of the erroneous responses for an example item pair and demonstrate that there are very significant differences between the types of errors in fast and slow responses.
Parallel multi‐level 2D‐DWT on CUDA GPUs and its application in ring artifact removal

This paper presented two schemes of parallel 2D discrete wavelet transform (DWT) on Compute Unified Device Architecture graphics processing units. For the first scheme, the image and filter are transformed to spectral domain by using Fast Fourier Transformation (FFT), multiplied and then transformed back to space domain by using inverse FFT. For the second scheme, the image pixels are convolved directly with filters. Because there is no data relevance, the convolution for data points on different positions could be executed concurrently. To reduce data transfer, the boundary extension and down‐sampling are processed during data loading stage, and transposing is completed implicitly during data storage. A similar skill is adopted when parallelizing inverse 2D DWT. To further speed up the data access, the filter coefficients are stored in the constant memory. We have parallelized the 2D DWT for dozens of wavelet types and achieved a speedup factor of over 380 times compared with that of its CPU version. We applied the parallel 2D DWT in a ring artifact removal procedure; the executing speed was accelerated near 200 times compared with its CPU version. The experimental results showed that the proposed parallel 2D DWT on graphics processing units can significantly improve the performance for a wide variety of wavelet types and is promising for various applications.

Graceful degradation of the quality of control through data drop policy

Sharing a network link in a networked control system (NCS) may result in the network overload leading to the non respect of the specified periodicity of control system, this may cause an unpredictable performance degradation of the system. In this paper, we consider an overload management technique which selectively drops the data packets of the NCS to avoid network overload. The investigated problems are: how to design the controller under packet drops and how to distribute the packet drops in a packet delivery sequence so that the quality of control (QoC) is optimized. The paper first gives the optimal LQ-controller using the conventional technique to reduce the deterioration in QoC due to packet drops. Then, the paper proposes a methodology for deriving a distribution of the packet drops in the packet delivery sequence so that the QoC is optimal. Finally, an efficient algorithm is given to reduce the computation complexity of the proposed methodology. This proposal contributes to the co-design of the controller and the resource performance management process at the implementation level.
Polarimetric SAR Denoising Using Adaptive Prediction Technique

In this paper, we propose a new filtering scheme based on adaptive predictive technique that operates simultaneously in polarisation and spatial domains. The weighting coefficients of the proposed filter are computed adaptively using the least mean square (LMS) algorithm. The LMS algorithm introduces a new parameter which is the updating step size. This parameter controls the performance of the proposed filtering algorithm. The optimal step size should satisfy a good compromise between speckle reduction and preservation of the texture and the polarimetric information. The experimental results show that, using both spatial and polarisation information, we get filtering performances better than using only the multipolarisation or the spatial information.
Wireless Handhelds to Support Clinical Nursing Practicum

This paper reports our implementation and evaluation of a wireless handheld learning environment used to support a clinical nursing practicum course. The learning environment was designed so that nursing students could use handhelds for recording information, organizing ideas, assessing patients, and also for interaction and collaboration with peers during an on-site clinical practicum. Our wireless handheld learning environment was field tested during a three-week practicum session. Analysis of data showed that both the instructor and the student benefited from using the Personal Digital Assistant (PDA) environment. The handhelds not only provided students with scaffolds to enhance learning but also facilitated peer cooperation and interaction with the instructor. Issues resulted from our implementation included things like the capacity of handhelds, network access, and participants’ preconceptions on using PC-based systems.
Title Collision-Free Asynchronous Multi-Channel Access in Ad Hoc Networks Permalink

In this paper, we present a collision-free asynchronous multi-channel access protocol for Ad Hoc wireless networks using a single transceiver. Our protocol, dubbed AM-MAC for Asynchronous Multi-channel Medium Access Control, targets low-cost, low-power deployments where nodes are equipped with a single transceiver. Other distinguishing features of AM-MAC include its simplicity and the fact that it does not require temporal synchronization among nodes. This is accomplished through an asynchronous split phase together with an observation phase as well as an unique handshake. Nodes observe the control channel for a period of time before asynchronously switching to the negotiated channel. Protocol correctness and collision-freedom in a multi-channel environment are verified. We also provide an analytical throughput assessment for our multichannel approach. Simulation results show that AM-MAC improves performance significantly when compared to IEEE 802.11. Our simulations also show that AM-MAC exhibits comparable performance to MMAC, a well-known multi-channel medium access control protocol, without the need for temporal synchronization.
Semantic interface for machine-to-machine communication in building automation

Current trends and advancements in the Internet of Things and the Semantic Web have already found their way into the domain of building automation. As machine-to-machine communication and integration of heterogeneous building automation technologies are of increasing importance, interoperability is a necessary precondition. In order to support building automation communication, a customized set of services needs to be available. Additionally, semantics of exchanged information has to be described in a machine-readable way to enable automatic interpretation of message contents. In this work, an interface based on Web technologies and Semantic Web standards is presented, which supports platform-independent machine-to-machine communication for building automation. A requirements analysis for such an interface leads to the definition of a service-oriented architecture. The semantics of exchanged message contents is described in an ontology that provides the basis for a common understanding. Moreover, feasibility and hardware requirements of the proposed approach are evaluated.
Segmentation of Bank Customers by Age

Viewing customers on the basis of age groupings is valuable in terms of product development, promotion and evaluation of delivery systems. The close association between customer age and product usage suggests a life cycle rather than a strict segmentation approach to marketing. A bank must realise that financial needs change as a customer matures, and anticipate and provide for these changing needs in order to build a solid customer base. Research into the users of 31 retail banks in a Midwestern US state indicates that there is a greater chance of success in promoting certain products to a particular age group, and that product usage tends to support the assumption that user age is a primary factor in bank product selection.
Towards an Understanding of the Evolution of the Chorioallantoic Placenta: Steroid Biosynthesis and Steroid Hormone Signaling in the Chorioallantoic Membrane of an Oviparous Reptile1

ABSTRACT Amniotes, mammals, reptiles, and birds form common extraembryonic membranes during development to perform essential functions, such as protection, nutrient transfer, gas exchange, and waste removal. Together with the maternal uterus, extraembryonic membranes of viviparous (live-bearing) amniotes develop as an endocrine placenta that synthesizes and responds to steroid hormones critical for development. The ability of these membranes to synthesize and respond to steroid hormone signaling has traditionally been considered an innovation of placental amniotes. However, our laboratory recently demonstrated that this ability extends to the chorioallantoic membrane (CAM) of an oviparous (egg-laying) amniote, the domestic chicken, and we hypothesized that steroidogenic extraembryonic membranes could be an evolutionarily conserved characteristic of all amniotes because of similarities in basic structure, function, and shared evolutionary ancestry. In this study, we examined steroid hormone synthesis and signaling in the CAM of another oviparous amniote, the American alligator (Alligator mississippiensis). We quantified mRNA expression of a steroidogenic factor involved in the regulation of steroidogenesis (NR5A1), the key steroidogenic enzymes involved in the synthesis of progestins (HSD3B1), androgens (CYP17A1), and estrogens (CYP19A1), and the receptors involved in the signaling of progestins (PR), androgens (AR), estrogens (ESR1 and ESR2), and glucocorticoids (GR). Furthermore, we performed protein immunolocalization for PR and ESR1. Collectively, our findings indicate that the alligator CAM has the capability to regulate, synthesize, and respond to steroid hormone signaling, thus, supporting our hypothesis that the extraembryonic membranes of Amniota share a unifying characteristic, that is, the ability to synthesize and respond to steroid hormones.
A Conceptual Model for Investigating the Possibility Effect of Environmental Uncertainty on the Relationship between Supply Chain Operational Capabilities and Business Performance

This paper expands previous research by modelling the contingency effect of environmental uncertainty on the relationship between supply chain operational capabilities (SCOC) and business performance. Previous research found that there is strong relationship between SCOC and business performance. However, the contingency effect of environmental uncertainty is not included. In addition, the last research was focused on SMEs, but similar study related to creative industries is rarely to find. Even, creative industries have similarities to SMEs. Therefore, focusing on creative industries and adding environmental uncertainty in different country (Indonesia) would enrich the generalization, especially the issue in supply chain management. This paper also contributes to provide guidance in terms of relationship among the constructs in theoretical model for the managers of creative industries.
The Paf1 Complex Is Essential for Histone Monoubiquitination by the Rad6-Bre1 Complex, Which Signals for Histone Methylation by COMPASS and Dot1p*

Monoubiquitination of histone H2B, catalyzed by Rad6-Bre1, is required for methylation of histone H3 on lysines 4 and 79, catalyzed by the Set1-containing complex COMPASS and Dot1p, respectively. The Paf1 protein complex, which associates with RNA polymerase II, is known to be required for these histone H3 methylation events. During the early elongation stage of transcription, the Paf1 complex is required for association of COMPASS with RNA polymerase II, but the role the Paf1 complex plays at the promoter has not been clear. We present evidence that the Paf1 complex is required for monoubiquitination of histone H2B at promoters. Strains deleted for several components of the Paf1 complex are defective in monoubiquitination of histone H2B, which results in the loss of methylation of lysines 4 and 79 of histone H3. We also show that Paf1 complex is required for the interaction of Rad6 and COMPASS with RNA polymerase II. Finally, we show that the Paf1 complex is required for Rad6-Bre1 catalytic activity but not for the recruitment of Rad6-Bre1 to promoters. Thus, in addition to its role during the elongation phase of transcription, the Paf1 complex appears to activate the function but not the placement of the Rad6-Bre1 ubiquitin-protein ligase at the promoters of active genes.
The Evolution of Marketing in Small Firms

Considers the characteristics of small firms from a marketing perspective. Examines the marketing undertaken by firms at different stages of development from start‐up to the medium‐sized firm. Proposes that this normally consists of four stages: initial marketing strategy; reactive selling; the DIY Marketing approach; and integrated proactive stages. Looks at these stages, suggesting that these provide a framework and starting point for further analyses of small businesses.
