AN INVESTIGATION ON RELATION AND PREDICTION OF PERCEIVED ORGANIZATIONAL SUPPORT (POS) ACCORDING TO 15 FOLD ORGANIZATIONAL VARIABLES

The aim of this article is to study the relation between perceived organizational support(POS) with 15 fold variables including cooperation in decision making, servicing the public, job vision, trust to supervisor, satisfaction with salary, promotion opportunity, inner provocation, quality of supervising, desire to remain, leaving the job, organizational trust, job interest, satisfaction with supervisor and satisfaction with colleagues. In order to achieve the foregoing aim, there were 198 people selected from all employed personnel in Rahpooyan Company and answered the questionnaires. The document related to validity and reliability of this investigation means were in an acceptable level. The data collected from these questionnaires was analysed via coefficient of Pierson correlation, analysis of step by step regression, analysis of structural equation (path analysis). The results indicate there was a significant correlation between perceived organizational support and including cooperation in decision making, servicing the public, job vision, trust to supervisor, satisfaction with salary, promotion opportunity, quality of supervising, desire to remain, leaving the job, organizational trust, satisfaction with supervisor and satisfaction with colleagues. But there was no significant correlation between inner provocation and job interest with perceived organizational support. In analysis of step by step regression, it was also indicated that cooperation in decision making, promotion opportunity, trust to supervisor, job interest and organizational trust can specify about 56% of the perceived organizational support variance. The results of the path analysis also indicated that cooperation in decision making, promotion opportunity, trust to supervisor, job interest have a coefficient of direct path on perceived organizational support.
3-D real-time gesture recognition using proximity spaces

A 3D segment tracking approach to recognition of human pose and gestures is presented. The author has previously developed and refined a stereo based method, called the proximity space method, for acquiring and maintaining the track of object surfaces in 3-space. This method uses LoG filtered images and relies solely on stereo measurement to spatially distinguish between objects in 3D. The objective of the work is to obtain useful state information about the shape, size, and pose of natural (unadorned) objects in their naturally cluttered environments. Thus, the system does not require or benefit from special markers, colors, or other tailored artifacts. Recently he has extended this method in order to track multiple regions and segments of complex objects. The paper describes techniques for applying the proximity space method to a particularly interesting system: the human. Specifically, he discusses the use of simple models for constraining proximity space behavior in order to track gestures as a person moves through a cluttered environment. It is demonstrated that by observing the behavior of the model, used to tract the human's pose through time, different gestures can be easily recognized. The approach is illustrated through a discussion of gestures used to provide logical and spatial commands to a mobile robot.
Incidence and outcome of schizophrenia in Whites, African-Caribbeans and Asians in London

Background. Several previous studies have indicated high rates of schizophrenia in African-Caribbeans in the UK compared to White population. Method. All people aged 18 to 64 years residing in two health districts in London who made contact with hospital or community services over a 1-year (Whites) or 2-year (ethnic minorities) period were screened for psychotic symptoms. Results. One hundred and twenty-three patients passed the screen, of whom 100 were assigned a schizophrenic class by the CATEGO program. Of these, 38 were White, 38 African-Caribbean and 24 Asian. The incidence rate for broad schizophrenia was significantly higher for African-Caribbeans than for Whites. Asians showed a high rate among people age 30 and over, particularly women. Poor outcome at 1-year follow-up was significantly more common for African-Caribbeans than for the other two groups. The proportion of African-Caribbeans with a poor outcome was two and a half times greater than that of Whites. On a range of seven socio-demographic variables, African-Caribbeans differed from the other two groups only on unemployment. Conclusions. A multitide of factors play a role in the aetiology of schizophrenia. Comparison of environmental factors in these groups may identify factors that contribute to the aetiology of schizophrenia.
Better Approximation Algorithms and Tighter Analysis for Set Splitting and Not-All-Equal Sat

We construct new approximation algorithms for Max Set Splitting and Max Not-All-Equal Sat, which when combined with existing algorithms give the best approximation results so far for these problems. Furthermore, when analyzing our combination of approximation algorithms, we introduce a novel technique, which improves the analysis of the performance ratio of such algorithms. In contrast with previous techniques we use a linear program to nd an upper bound on the performance ratio. This linear program can also be used to see which of the contributing algorithms it is possible to exclude from the combined algorithm without aaecting its performance ratio.
Incremental Trust in Grid Computing

This paper describes a comparative simulation study of some incremental trust and reputation algorithms for handling behavioural trust in large distributed systems. Two types of reputation algorithm (based on discrete and Bayesian evaluation of ratings) and two ways of combining direct trust and reputation (discrete combination and combination based on fuzzy logic) are considered. The various combinations of these methods are evaluated from the point of view of their ability to respond to changes in behaviour and the ease with which suitable parameters for the algorithms can be found in the context of Grid systems.

Determinants of skilled birth attendant utilization in Afghanistan: a cross-sectional study.

OBJECTIVES We sought to identify characteristics associated with use of skilled birth attendants where health services exist in Afghanistan. METHODS We conducted a cross-sectional study in all 33 provinces in 2004, yielding data from 617 health facilities and 9917 women who lived near the facilities and had given birth in the past 2 years. RESULTS Only 13% of respondents had used skilled birth attendants. Women from the wealthiest quintile (vs the poorest quintile) had higher odds of use (odds ratio [OR] = 6.3; 95% confidence interval [CI] = 4.4, 8.9). Literacy was strongly associated with use (OR = 2.5; 95% CI = 2.0, 3.2), as was living less than 60 minutes from the facility (OR = 1.5; 95% CI = 1.1, 2.0) and residing near a facility with a female midwife or doctor (OR = 1.4; 95% CI = 1.1, 1.8). Women living near facilities that charged user fees (OR = 0.8; 95% CI = 0.6, 1.0) and that had male community health workers (OR = 0.6; 95% CI = 0.5, 0.9) had lower odds of use. CONCLUSIONS In Afghanistan, the rate of use of safe delivery care must be improved. The financial barriers of poor and uneducated women should be reduced and culturally acceptable alternatives must be considered.
An Efficient Mechanism for Power Control Optimization in MBMS Enabled UTRAN

This paper proposes a power control mechanism for the efficient radio bearer selection in the Multimedia Broadcast/Multicast Service (MBMS) framework of Universal Mobile Telecommunications System (UMTS). The selection of the most efficient transport channel in terms of power consumption is a key point for MBMS enabled UMTS networks, since a wrong transport channel selection for the transmission of the MBMS data could result to a significant decrease in the total capacity of the network. Different UMTS transport channels and power saving techniques are examined and an algorithm that selects the most efficient combination of the above parameters is proposed. The proposed MBMS power control mechanism selects the transport channel that minimizes the base station's transmission power in every cell of the network that serves multicast users.

Buffer on Last Level Cache for CPU and GPGPU Data Sharing

With the rapid growth in demand of massive data processing and the limitation of process development in microprocessor, GPGPU gains more and more attentions to provide huge power of data parallelism. Tightly-coupled CPU and GPGPU that share the LLC (last level cache) enables fine-grained workload offload between CPU and GPGPU. In the paper, we focus on one data transfer pattern where the data are usually in form of independent element, each of which is to be processed by the other processor when it is ready. Traditionally, CPU prepares all the data that are to be processed by GPGPU before starting GPGPU. This creates long waiting time, and the shared LLC may suffer from cache trashing if the work set can not fit in the LLC. To alleviate these problems, we propose the LLC buffer as a data transfer mechanism between CPU and GPGPU on shared LLC. The LLC buffer exploits part of LLC storage to work as one or more stream buffers, and stashes each data element as an independent transfer unit. With the help of LLC buffer, we achieve an average speedup of 1.48x and eliminate 1346x memory writes (cache evictions) from LLC.
[Prognostic value of ECGs in patients with type-2 diabetes mellitus without known cardiovascular disease].

INTRODUCTION AND OBJECTIVES The predictive value of ECG abnormalities in patients with type-2 diabetes mellitus (DM2) has not been fully studied. Our objective was to assess the prognostic value of ECG abnormalities in patients with DM2 but without known cardiovascular disease. METHODS Overall, 412 patients with DM2 were identified at two primary care centers in the same city. Two hundred and twenty one patients younger 80 years without known cardiovascular disease were included in the study. An ECG was recorded at baseline and annually during follow-up. The ECGs were evaluated using a system based on the Minnesota code. The main study end-point during follow-up was the occurrence of a cardiovascular event, as defined in the Framingham study. RESULTS The mean follow-up duration was 5.9 years (1.1-8.5 years). At the beginning of the study, 24.9% of patients had ECG abnormalities; at the end, 44.3% had abnormalities. Cardiovascular events occurred in 65 patients (29.4%). The relative risk (RR) of a cardiovascular event in a patient with an ECG abnormality was 8.28 (95% confidence interval [CI], 3.36-20.42). Only hypertension (RR = 2.29; 95% CI, 1.24-4.22) and age were significantly related to the occurrence of a cardiovascular event. Multiple regression analysis that included classical risk factors and ECG findings showed that an ECG abnormality was a significant independent predictor, with adjusted RR = 5.95 (95% CI, 2.29-15.47). CONCLUSIONS The presence of an ECG abnormality can predict the occurrence of a future cardiovascular event in patients with DM2 more accurately than risk factors alone. This finding could be helpful in selecting subgroups of high-risk diabetic patients.
Clinical Study of Respiratory Function and Difference in Pneumonia History between Alzheimer’s Disease and Vascular Dementia Groups

[Purpose] This study compared respiratory function and differences in pneumonia history between Alzheimer’s disease and vascular dementia groups. [Subjects] Fifty-eight inpatients in the dementia treatment ward in a psychiatric facility were enrolled. [Methods] Patients underwent respiratory function testing twice using an 80-cm party horn. The Mini-Mental State Examination was also performed and motor functions were evaluated. Patient characteristics were obtained from medical records. [Results] Significant differences were noted between Alzheimer’s disease and vascular dementia groups in the ability to blow the party horn to full length, pneumonia history, and presence of impaired mobility. [Conclusion] Party horn evaluation may be useful for determining the risk of pneumonia in patients with dementia.
Activity in prelimbic cortex subserves fear memory reconsolidation over time

The prelimbic cortex has been implicated in the consolidation of previously learned fear. Herein, we report that temporarily inactivating this medial prefrontal cortex subregion with the GABAA agonist muscimol (4.0 nmol in 0.2 μL per hemisphere) was able to equally disrupt 1-, 7-, and 21-d-old contextual fear memories after their brief retrieval in rats. In all cases, this effect was prevented when memory reactivation was omitted. These results indicate that recent and remote fear memories are susceptible to reconsolidation blockade induced by prelimbic cortex inactivation. It was also demonstrated that the disrupting effect of prelimbic cortex inactivation on fear memory persisted over 11 d, and did not show extinction-related features, such as reinstatement. Infusing the same dose and volume of muscimol bilaterally into the infralimbic cortex after brief retrieval/reactivation of the fear memory did not disrupt it, as seen in prelimbic cortex-inactivated animals. The expression of Zif268/Egr1, the product of an immediate early gene related to memory reconsolidation, was also less pronounced in the infralimbic cortex than in prelimbic cortex following memory retrieval/reactivation. Altogether, the present findings highlight that activity in the prelimbic cortex may reestablish reactivated aversive memories and, therefore, contribute to their maintenance over time.
Analysis of MRI-based cortical surface structure complexity in dementia by sample entropy

Dementia is a most common neurodegenerative disorder. Previous researches have attempted to relate the impairment of cognition to volumes or thickness changes of the cortical regions, with relatively few studies investigating other features such as cortical surface anatomy. In the present study, we report for the first time to use sample entropy (SampEn) to assess the complexity of cortical surface structure in early stage of dementia compared to healthy controls. Whole brain structural T1-weighted MRI scans were collected from 192 subjects including patients with very mild and mild dementia (age = 77 ± 7, male/female = 41/55, CDR = 0.5 or 1, n = 96), and healthy subjects (aged = 76 ± 9, male/female= 25/70, CDR = 0, n = 96). SampEn was applied to each transection and averaged. Comparisons were made between control and dementia for the whole brain as well as for each sub-section of all layers. Results show an overall larger SampEn in demented group compared with non-demented group(p <; 0.05) which indicate an increase of structural irregularity of cortical surface in dementia. Our findings offer a novel approach for studying cortical atrophy patterns and can potentially be used to develop novel biomarkers of dementia.
Gestures in human-robot interaction: development of intuitive gesture vocabularies and robust gesture recognition

Gestures consist of movements of body parts and are a mean of communication that conveys information or intentions to an observer. Therefore, they can be effectively used in human-robot interaction, or in general in human-machine interaction, as a way for a robot or a machine to infer a meaning, e.g., a person’s particular intention or state. In order for people to intuitively use gestures and understand robot gestures, it is necessary to define mappings between gestures and their associated meanings – a gesture vocabulary. The task is to determine human and robot gesture vocabularies. In the former case, the vocabulary defines which gestures a group of people would intuitively use to convey information, while in the latter case, it displays which robot gestures are deemed as fitting for a particular meaning. Once these vocabularies are defined, their effective use depends on techniques for gesture recognition, which considers classification of body motion into discrete gesture classes, relying on pattern recognition and machine learning. This thesis addresses both research areas, presenting development of gesture vocabularies as well as gesture recognition techniques, focusing on hand and arm gestures. Prior to the gesture vocabularies and recognition, attentional models for humanoid robots were developed as a prerequisite for human-robot interaction and a precursor to gesture recognition. A method for defining gesture vocabularies for humans and robots, based on user observations and surveys, is explained and experimental results are presented. As a result of the robot gesture vocabulary experiment, an evolutionary-based approach for refinement of robot gestures is introduced, based on interactive genetic algorithms. A robust and well-performing gesture recognition algorithm based on dynamic time warping has been developed. Most importantly, it employs one-shot learning, meaning that it can be trained using a low number of training samples and employed in real-life scenarios, lowering the effect of environmental constraints such as relative positions and orientations of the sensor and the person, and gesture features. Finally, an approach for learning a relation between self-motion and pointing gestures is presented.
Parents' safety beliefs and childhood agricultural injury.

BACKGROUND This study examined potential associations between parental safety beliefs and children's chore assignments or risk of agricultural injury. METHODS Analyses were based on nested case-control data collected by the 1999 and 2001 Regional Rural Injury Study-II (RRIS-II) surveillance efforts. Cases (n = 425, reporting injuries) and controls (n = 1,886, no injuries; selected using incidence density sampling) were persons younger than 20 years of age from Midwestern agricultural households. A causal model served as the basis for multivariate data analysis. RESULTS Decreased risks of injury (odds ratio [OR] and 95% confidence intervals [CI]) were observed for working-aged children with "moderate," compared to "very strict" parental monitoring (0.60; 0.40-0.90), and with parents believing in the importance of physical (0.80; 0.60-0.95) and cognitive readiness (0.70, 0.50-0.90, all children; 0.30, 0.20-0.50, females) when assigning new tasks. Parents' safety beliefs were not associated with chore assignments. CONCLUSIONS Parents' safety beliefs were associated with reduced risk of childhood agricultural injury; the association was not mediated by chore assignments.

Effect of seeding during thermophilic composting of sewage sludge

The effect of seeding on the thermophilic composting of sewage sludge was examined by measuring the changes in CO2 evolution rates and microbial numbers. Although the succession of thermophilic bacteria and thermophilic actinomycetes clearly reflected the effect of seeding, no clear difference was observed in the overall rate of composting or quality of the composted product.
Who is Afraid of Reg Fd? The Behavior and Performance of Sell-Side Analysts Following the Sec's Fair Disclosure Rules

We examine Regulation FD's impact on the accuracy and dispersion of sell-side analysts' earnings forecasts. Using a large sample of quarterly forecasts made over a nearly 10-year period surrounding FD's adoption, we uncover two main sets of findings. First, individual and consensus forecasts become less accurate post-FD, particularly for early forecasts and for smaller companies. Second, forecast dispersion increases post-FD. This effect is stronger for early forecasts and has increased with the passage of time. These results, which are quite robust to alternative empirical methodologies, suggest that there has been a reduction in both selective guidance and forecast quality post-FD.
Credit Spread Specification and the Pricing of Spread Options

This paper presents a simple approach to the pricing of options on spread and some arguments in favor of modelling the spread using its two components instead of the spread itself. We show that, even in a simple Gaussian setting, the spread should not be modelled directly, and that convergence speeds of the two components are crucial parameters. There exist conditions, discussed in this paper, under which the analysis can be reduced to a two-factor model based on the dynamics of the spread itself. Hence, we propose a three-factor model based on the dynamics of the riskless rate and of the two components of the spread. This is done by following the Longstaff (1990) methodology and with the assumption that both the riskless rate and the spread or its two components follow correlated Ornstein-Uhlenbeck processes. Greeks analysis shows that spread options have some very specific features compared to the Black-Scholes-Merton (1973) option model. Moreover, the results show that the mispricing is important and not systematic when one chooses a spread option model based on the dynamics of the spread instead of using the dynamics of its two components. We finally show how the spread option model allows us to price other yield derivatives, like options to exchange a yield for another or the options on the maximum or the minimum of two yields.
