Comparison of human resource management practices and perceptions of agri -business employees across three Indonesian subcultures

Comparison of Human Resource Management Practices and Perceptions of Agri-Business Employees Across Three Indonesian Subcultures. (May 2008) Mark Christopher Kelly, B.S.; B.A., University of North Carolina Wilmington; M.S., Texas A&M University Co-Chairs of Advisory Committee: Dr. Kim E. Dooley Dr. Michael J. McCormick Prior research has shown that differences in human resource management (HRM) perception/practices do exist between nations. These differences have been attributed to variations in culture. The fundamental purpose of this study was to determine whether subcultures differing in location, religion, and ethnicity significantly affect perception/ practices of human resource management within a common national context (Indonesia). A secondary purpose of the current study was to compare with those found within Indonesia by the Best International Practices Consortium or Best Practices Project (BPP). Participants in the present study were 762 agri-business employees who were members of three distinctly separate subcultures within Indonesia; Sundanese/ Javanese, Balinese, and Minahasan. Data are obtained through the distribution of written questionnaires modeled after those employed by the BPP.
The maturation of auditory responses in infants and young children: a cross-sectional study from 6 to 59 months

Background: An understanding of the maturation of auditory cortex responses in typically developing infants and toddlers is needed to later identify auditory processing abnormalities in infants at risk for neurodevelopmental disorders. The availability of infant and young child magnetoencephalography (MEG) systems may now provide near optimal assessment of left and right hemisphere auditory neuromagnetic responses in young populations. To assess the performance of a novel whole-head infant MEG system, a cross-sectional study examined the maturation of left and right auditory cortex responses in children 6- to 59-months of age. Methods: Blocks of 1000 Hz (1st and 3rd blocks) and 500 Hz tones (2nd block) were presented while MEG data were recorded using an infant/young child biomagnetometer (Artemis 123). Data were obtained from 29 children (11 males; 6- to 59-months). Latency measures were obtained for the first positive-to-negative evoked response waveform complex in each hemisphere. Latency and age associations as well as frequency and hemisphere latency differences were examined. For the 1000 Hz tone, measures of reliability were computed. Results: For the first response—a response with a “P2m” topography—latencies decreased as a function of age. For the second response—a response with a “N2m” topography—no N2m latency and age relationships were observed. A main effect of tone frequency showed earlier P2m responses for 1st 1000 Hz (150 ms) and 2nd 1000 Hz (148 ms) vs. 500 Hz tones (162 ms). A significant main effect of hemisphere showed earlier N2m responses for 2nd 1000 Hz (226 ms) vs. 1st 1000 Hz (241 ms) vs. 500 Hz tones (265 ms). P2m and N2m interclass correlation coefficient latency findings were as follows: left P2m (0.72, p < 0.001), right P2m (0.84, p < 0.001), left N2m (0.77, p < 0.001), and right N2m (0.77,p < 0.01). Conclusions: Findings of strong age and latency associations, sensitivity to tone frequency, and good test-retest reliability support the viability of longitudinal infant MEG studies that include younger as well as older participants as well as studies examining auditory processing abnormalities in infants at risk for neurodevelopmental disorders.
Rapid Alkalinization Factors in Poplar Cell Cultures. Peptide Isolation, cDNA Cloning, and Differential Expression in Leaves and Methyl Jasmonate-Treated Cells1

A family of peptides inducing rapid pH alkalinization in hybrid poplar (Populus trichocarpa × Populus deltoides) cell culture medium was isolated from hybrid poplar leaves. Five related approximately 5-kD peptides were purified by high-performance liquid chromatography and analyzed by matrix-assisted laser desorption ionization-mass spectrometry. The N-terminal sequence of one of the isolated peptides was very similar to a previously characterized peptide from tobacco (Nicotiana tabacum), rapid alkalinization factor (RALF), which causes a rapid increase in culture medium pH when added to tobacco cell cultures (G. Pearce, D.S. Moura, J. Stratmann, C.A. Ryan [2001] Proc Natl Acad Sci USA 98: 12843–12847). Two unique poplar RALF cDNAs (PtdRALF1 and PtdRALF2) were isolated from a poplar cDNA library and used to study RALF expression in poplar saplings and cultured poplar cells. Both genes were found to be expressed constitutively in poplar saplings and cultured cells. However, PtdRALF2 was expressed in leaves at very low levels, and its expression in suspension culture cells was transiently suppressed by methyl jasmonate (MeJa). Although the function of these novel peptides remains enigmatic, our experiments suggest their role may be developmental rather than stress related. Overall, our study confirms the presence of active RALF peptides in other plants, and provides new data on the complexity of the RALF gene family in poplar.
Modeling, Deploying, and Controlling Volatile Functionalities in Web Applications

One of the main characteristics of most Web applications is their high dynamism. Once implemented and deployed for the first time, new functionalities are added to meet new or changed requirements. Some of these functionalities may appear on the Web in response to an unexpected event, or phenomena (such as a natural calamity) after which they are removed. Some others are activated periodically, to coincide with a particular date, or period of the year (such as, return to school, Christmas holidays, etc.). Implementing such volatile functionalities usually impacts on a number of aspects of a Web application, including content, navigation, presentation, business processes, and user operations. Their cyclic activation/deactivation, which requires repetitive changes in the application code, may be the cause of waste of effort and application quality deterioration, up to incorrect functioning. In this paper, we present an approach to decouple the design and implementation of volatile functionalities from that of stable ones, i.e. the core functionalities of the application. The approach is instantiated in the context of the Object-Oriented Hypermedia Design Method (OOHDM), but its principles and related techniques are generally applicable to any other Web engineering method. We show how our approach enables the deployment and removal of these functionalities in a cost-effective and safe way and at runtime, thus providing business agility. A framework to classify volatile functionalities and a number of examples are also reported.
Policy Incentives for Dangerous (But Necessary) Operations

In industries where firms perform dangerous (but necessary) operations, liability costs—due to potential harm to third parties—can be significant. Firms may therefore find it optimal to exit the market, and this may lead to an inefficiently low number of incumbents. A social planner can discourage exit by offering appropriately designed subsidies. Ex ante subsidies defray the costs associated with making operations safer (e.g., funds to subsidize the purchase of safety equipment). Ex post subsidies mitigate the financial damages caused by an accident (e.g., funds to defray the cost of cleaning up a toxic spill). We consider a model where (i) firms have private information about their ability to improve reliability and (ii) reliability investments are unobservable. We demonstrate that when the social value of reliability outweighs the benefit of increased competition, it is optimal to offer ex ante subsidies alone (i.e., to subsidize the cost of making operations safer). Conversely, when the benefits of competition outweigh the benefits of reliability, a combination of ex ante and ex post subsidies is optimal (i.e., not only to subsidize safer operations, but also to share the costs of a potential accident).
Aspect-Level Cross-lingual Sentiment Classification with Constrained SMT

Most cross-lingual sentiment classification (CLSC) research so far has been performed at sentence or document level. Aspect-level CLSC, which is more appropriate for many applications, presents the additional difficulty that we consider subsentential opinionated units which have to be mapped across languages. In this paper, we extend the possible cross-lingual sentiment analysis settings to aspect-level specific use cases. We propose a method, based on constrained SMT, to transfer opinionated units across languages by preserving their boundaries. We show that cross-language sentiment classifiers built with this method achieve comparable results to monolingual ones, and we compare different cross-lingual settings.
An Overview of Learning to Rank for Information Retrieval

This paper presents an overview of learning to rank. It includes three parts: related concepts including the definitions of ranking and learning to rank; a summary of pointwise models, pairwise models, and listwise models; estimation measures such as Normalized Discount Cumulative Gain and Mean Average Precision, respectively. Considering the deficiency that current learning to rank models lack of continual learning ability, we present a new continual learning idea that combines multi-agent autonomy learning mechanism with molecular immune mechanism for ranking.
Investigation of the THOR Anthropomorphic Test Device for Predicting Occupant Injuries during Spacecraft Launch Aborts and Landing

The objective of this study was to investigate new methods for predicting injury from expected spaceflight dynamic loads by leveraging a broader range of available information in injury biomechanics. Although all spacecraft designs were considered, the primary focus was the National Aeronautics and Space Administration Orion capsule, as the authors have the most knowledge and experience related to this design. The team defined a list of critical injuries and selected the THOR anthropomorphic test device as the basis for new standards and requirements. In addition, the team down-selected the list of available injury metrics to the following: head injury criteria 15, kinematic brain rotational injury criteria, neck axial tension and compression force, maximum chest deflection, lateral shoulder force and displacement, acetabular lateral force, thoracic spine axial compression force, ankle moments, and average distal forearm speed limits. The team felt that these metrics capture all of the injuries that might be expected by a seated crewmember during vehicle aborts and landings. Using previously determined injury risk levels for nominal and off-nominal landings, appropriate injury assessment reference values (IARVs) were defined for each metric. Musculoskeletal deconditioning due to exposure to reduced gravity over time can affect injury risk during landing; therefore a deconditioning factor was applied to all IARVs. Although there are appropriate injury data for each anatomical region of interest, additional research is needed for several metrics to improve the confidence score.
Evaluation comparison of AODV DSR and OLSR in ad hoc networks routing protocols

Mobile ad hoc networks (MANETs) are categorized by multi-hop wireless connectivity, frequently varying network topology and the need for efficient dynamic routing protocols plays an important role. A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication among these mobile nodes is carried out without any centralized control. MANET is a self-configurable andself-organized network where the mobile nodes move randomly. The mobile nodes can accept and forward packets as a router. Routing is a serious issue in MANET and hence the focus of this thesis along with the performance analysis of routing protocols. A variety of routing protocols targeted specifically at this environment have been developed and some performance simulations are made on numbers of routing protocols like Ad hoc OnDemand Distance Vector Routing (AODV), Dynamic Source Routing (DSR) and Open Link State Routing (OLSR). We compared three routing protocols i.e. AODV, OLSR andDSR. Our simulation tool will be OPNET modeller. The presentation of these routing protocols is examined by three metrics: delay,throughput andnetwork load. All the three routing protocols are explained in a deep way with metrics. The comparison study will be carrying out about these protocols and in the last the conclusion will be presented, that which routing protocol is the finest one for mobile ad hoc networks.
Modelled polarimetric backscattering response from single pine trees and pine canopies

In this work a coherent backscattering model has been employed to simulate L-band polarimetric backscattering from a single pine tree and a small pine forest stand. The recently developed 'Electromagnetic Scattering Model for Forest Remote Sensing' has been employed in calculations. The backscattering model uses the discrete particle approach and it can handle first order direct scattering, single and double ground bounce terms, and first order interaction between the trunk and branches. The model computes fully coherent polarimetric quantities for any construction made of cylinders. Tree cylinder models for simulations are created with the LIGNUM tree growth model. The polarimetric covariance matrix for the tree has been calculated as an average over tree azimuth angles. The target entropy and alpha angle are examined as a function of tree stem volume. EMISAR images from 1995 from Finland are used in comparison . Results indicate that the model can predict correctly behaviour of direct backscattering, but the ground bounce terms suffer from simplifications made as ground is modelled as a perfectly smooth surface. However, the model is able to predict correctly scattering mechanism change as a function of stem volume.
Sneaky side effects and ineffectiveness of an immunotherapy with ipilimumab in a case of metastatic melanoma

ABSTRACT Ipilimumab is an anti-CTLA-4 antibody that is approved for the treatment of metastatic malignant melanoma. Side-effects are mostly immune-mediated and in many cases the lack of specific symptoms leads to delayed diagnosis and treatment of adverse events. We present the case of a female patient who experienced an uncommon combination of adverse reactions while undergoing therapy with ipilimumab and where the absence of specificity of the symptoms led to late diagnosis and treatment of side effects. Autoimmune disease was neither associated with tumor response nor with prolonged survival.
Structured Coupon Collection over Cliques for P 2 P Load Balancing

We study Structured Coupon Collection, a problem introduced by Adler et al [AHKV03] in STOC 2003, over n/b disjoint cliques with b nodes per clique. Nodes are initially uncovered. At each step, we choose d nodes independently and uniformly at random. If all the nodes in the corresponding cliques are covered, we do nothing. Otherwise, from among the chosen cliques with at least one uncovered node, we select one at random and cover an uncovered node within that clique. We show that as long as bd ≥ c log n, O(n) steps are sufficient to cover all nodes w.h. p. and each of the first Ω(n) steps succeed in covering a node w.h. p. These results are then utilized to analyze a stochastic process for growing binary trees that are highly balanced – the leaves of the tree belong to at most four different levels w.h. p. The stochastic process constitutes the core idea underlying a practical P2P load balancing scheme that beats earlier proposals for the same, in terms of message complexity.
Increasing the efficiency of the Persian Sign Language system based on new preprocessing method

In this paper, a systems is presented to recognize static gesture of alphabets in Persian Sign Language (PSL). The implemented system does not need any gloves or visual marking system, and just uses images captured by camera to recognize PSL alphabets. This system contains three principal phase: preprocessing, feature extraction, and classification. Preprocessing phase includes using several preprocessing methods on the image which reduces the difference among the hand gesture in the same letter group. In the second phase, Hough Transform function is used for feature extraction from images and MLP NN is used for image classification in the third phase. Results of the paper show that in spite of applying several preprocessing methods on images, the time of neural network training is reduced. Furthermore the recognition rate of PLS improves considerably. This system is able to recognize every 37 PSL alphabet by 98.91% accuracy.
The impact of corporate social responsibility and risk management on financial performance: The case of Vietnamese textile firms

Article history: Received: March 3, 2019 Received in revised format: March 8 2019 Accepted: April 5, 2019 Available online: April 5, 2019 The objective of this study is to assess the impact of corporate social responsibility (CSR) and risk management (RM) on financial performance (FP), and evaluate the moderate role of firm size in the relationship between risk management and financial performance. The study was conducted on a research sample of 389 Vietnamese textile firms. The results show that corporate social responsibility (CSR) was an optimal measure to minimize risks and improves financial performance. The good CSR policy reduces corporate risk and improves financial performance. Other way, the bad CSR policy increases corporate risk and impacts negatively on financial performance. In addition, the moderate role of firm size in the relationship between risk management and financial performance is statistically significant. © 2019 by the authors; licensee Growing Science, Canada
Endogenous radial glial cells support regenerating axons after spinal cord transection

During the development of central nervous system, radial glial cells support target-specific neuronal migration. We recently reported that after implantation of chitosan channels with complete spinal cord transection, the tissue bridging the spinal cord stumps contained axons and radial glial cells. The purpose of this study was to clarify the role of the radial glial cells in the tissue bridges. Chitosan channels were implanted in rats with thoracic spinal cord transection. After 14 weeks, all animals had tissue bridges in the channels that contained many radial glial cells in longitudinal arrangement, some of which were in contact with axons in the bridges. We suggest that radial glial cells can guide regenerating axons across the bridge in the channel after spinal cord transection.
Determinants of Initial Satisfaction with the Succession Process in Family Firms: A Conceptual Model

Leadership succession continues to form the core of the family business literature. Numerous studies have suggested factors that influence family members' initial satisfaction with the succession process, but this body of work is highly fragmented and lacks a unifying framework. In this paper, we draw on stakeholder theory and other organizational, behavioral, and economic theories to develop a conceptual model that integrates the findings from the literature. The research and practical implications of this integrative, ready-to-test, model are discussed.
Bousfield ’ s E 2 model theory for simplicial objects

are weak equivalences of simplicial groups. This definition amounts to a comparison of E2-terms in homotopy group spectral sequences for the simplicial spaces at hand, hence the name. The point of the construction is to develop a flexible theory of simplicial resolutions for spaces. There is a remark in [2] that the methods of that paper should work for any category of simplicial objects in a closed simplicial model category M in which every object is fibrant. This is worked out by Goerss and Hopkins in [3], for simplicial objects in a cofibrantly generated topological model categoryM in which every object is fibrant. There is a further departure in [3] which was triggered by the intended applications, in that they take a small diagram B of cogroup objects i 7→ Bi in M, and say that a map f : X → Y of simplicial objects in M is a B-equivalence if the comparison
Heuristics for Scheduling I/O Operations

The I/O bottleneck in parallel computer systems has recently begun receiving increasing interest. Most attention has focused on improving the performance of I/O devices using fairly low level parallelism in techniques such as disk striping and interleaving. Widely applicable solutions, however, will require an integrated approach which addresses the problem at multiple system levels, including applications, systems software, and architecture. We propose that within the context of such an integrated approach, scheduling parallel I/O operations will become increasingly attractive and can potentially provide substantial performance benefits. We describe a simple I/O scheduling problem and present approximate algorithms for its solution. The costs of using these algorithms in terms of execution time, and the benefits in terms of reduced time to complete a batch of I/O operations, are compared with the situations in which no scheduling is used, and in which an optimal scheduling algorithm is used. The comparison is performed both theoretically and experimentally. We have found that, in exchange for a small execution time overhead, the approximate scheduling algorithms can provide substantial improvements in I/O completion times.
Multistage IIR filter design using convex stability domains defined by positive realness

In this paper, we consider infinite impulse response (IIR) filter design where both magnitude and phase are optimized using a weighted and sampled least-squares criterion. We propose a new convex stability domain defined by positive realness for ensuring the stability of the filter and adapt the Steiglitz-McBride (SM), Gauss-Newton (GN), and classical descent methods to the new stability domain. We show how to describe the stability domain such that the description is suited to semidefinite programming and is implementable exactly; in addition, we prove that this domain contains the domain given by Rouche/spl acute/'s theorem. Finally, we give experimental evidence that the best designs are usually obtained with a multistage algorithm, where the three above methods are used in succession, each one being initialized with the result of the previous and where the positive realness stability domain is used instead of that defined by Rouche/spl acute/'s theorem.
General expansion-shifting model for reversible data hiding

Reversible data hiding (RDH) is a specific information hiding technique in which both the embedded data and the original cover medium can be exactly extracted from the marked data. In this paper, we present a general expansion-shifting model for RDH by introducing the so-called reversible embedding function (REF) which maps each point of Zn to a nonempty subset of Zn. Moreover, to guarantee the reversibility, the mapped subsets of distinct points should be disjoint from each other. With REF, RDH can be designed and the corresponding rate-distortion formulations can be established, providing a possibility to optimize the reversible embedding performance. Some examples of REF are given, and a preliminary theoretical investigation on REF is conducted as well.
