Cross-layer optimization of wireless networks using nonlinear column generation

We consider the problem of finding the jointly optimal end-to-end communication rates, routing, power allocation and transmission scheduling for wireless networks. In particular, we focus on finding the resource allocation that achieves fair end-to-end communication rates. Using realistic models of several rate and power adaption schemes, we show how this cross-layer optimization problem can be formulated as a nonlinear mathematical program. We develop a specialized solution method, based on a nonlinear column generation technique, and prove that it converges to the globally optimal solution. We present computational results from a large set of networks and discuss the insight that can be gained about the influence of power control, spatial reuse, routing strategies and variable transmission rates on network performance.
“It is like stepping into another world”: Exploring the possibilities of using appreciative participatory action research to guide culture change work in community and long-term care

This paper highlights the possibilities for transformation that exist when a diverse group of participants interested in working together to change the culture of dementia care in long-term care and community care settings use appreciative participatory action research to guide their culture change efforts. These transformations happened throughout the culture change process using appreciative participatory action research. For instance, using appreciative participatory action research to guide the culture change process provided participants with the opportunity to build stronger professional and personal relationships in their respective care communities. Culture change transformations also stemmed from the appreciative participatory action research process, as participants recognized the importance of finding ways to include persons with dementia/residents in the process and they developed an appreciation for the valuable contributions persons with dementia/residents can make to culture change work. These culture chance possibilities demonstrate the value in using appreciative participatory action research to guide culture change in long-term care and community care contexts. These possibilities also illustrate the importance of paying closer attention to the culture change process itself, rather than solely the outcomes of the process, given that the possibilities for transformation that can take place throughout the process can help to build momentum, propelling culture change efforts forward in healthcare contexts.
A Rule-Augmented Statistical Phrase-based Translation System

Interactive or Incremental Statistical Machine Translation (IMT) aims to provide a mechanism that allows the statistical models involved in the translation process to be incrementally updated and improved. The source of knowledge normally comes from users who either post-edit the entire translation or just provide the translations for wrongly translated domain-specific terminologies. Most of the existing work on IMT uses batch learning paradigm which does not allow translation systems to make use of the new input instantaneously. We introduce an adaptive MT framework with a Rule Definition Language (RDL) for users to amend MT results through translation rules or patterns. Experimental results show that our system acknowledges user feedback via RDL which improves the translations of the baseline system on three test sets for Vietnamese to English translation.
Lasker's coefficient of isonymy between and within 16 Sardinian villages in the periods 1825–1849, 1875–1899, and 1925–1949

Coefficients of relationship by isonymy, based on the frequency of common surnames, were used to estimate the biological affinity between (Rib) and within (Riw) 16 Sardinian villages in the periods 1825–1849, 1875–1899, and 1925–1949. The database for the surname analysis consisted of 13,515 marriages registered in the parishes of villages, all belonging to the Sardinian linguistic area. The values of Rib and Riw tend to decrease in time. In all three periods, the Rib values generally decrease as the geographical distance between villages increases. The negative values of the Bravais‐Pearson coefficient of correlation between the matrix of Rib values and the matrices of geographical distances (calculated both in a straight line and from road distances) are significant for each period (modified Mantel test), with slightly higher correlation coefficients for road distances. Moreover, the plots of isonymic relationships obtained by nonmetric multidimensional scaling for 1825–1849 and 1925–1949 show that the biological relationships between neighboring villages increase in the latter period. The positive values of the Bravais‐Pearson coefficients of correlation between Riw and altitude are significant in all three periods, while the correlation between Riw and population size is not significant, even when altitude is controlled for. Since altitude is considered an indicator of isolation, the results obtained with the coefficient of relationship by isonymy within villages also support the isolation‐by‐distance model. Rib values provided a reliable picture of the biological relationships between 16 Sardinian villages, while Riw values illustrated the biological affinity within the communities for a period of 100 years, from 1825–1849 to 1925–1949.

FPGA Based Real-Time Tracking Approach with Validation of Precision and Performance

This paper presents the implementation and validation of a tracking approach for image processing in hardware. It compares the implementation for the addressed problem on a Field Programmable Gate Array (FPGA) with a software implementation for a General Purpose Processor (GPP) architecture. For both solutions the implementation costs for their development is an important aspect in the validation. This research project is motivated by the MI6 project of the Computer Vision research group, which is located at the Bonn-Rhein-Sieg University of Applied Sciences. The intent of the MI6 project is the tracking of a user in an immersive environment. In this research work the development and validation of a detection system for BLOBs on a Cyclone II FPGA from Altera has been implemented. The analysis of the hardware solution showed a similar precision for the tracking as the software approach. One problem is the large increase of allocated resources when extending the system to process more objects. The implementation of the tracking approach in hardware required much more effort than the software solution. The design of high level problems in hardware for this case are more expensive than the software implementation. The results of the implementation indicate that a mixed hardware/software solution would provide optimal results.
Addressing the role of personality, ability, and positive and negative affect in positive psychology interventions: Findings from a randomized intervention based on the authentic happiness theory and extensions

The present study explores the role of personality, ability, and affect in a randomized, group-based positive psychology intervention program based on Seligman’s authentic happiness theory and extensions. A total of 100 adults (M = 45.7, SD = 12.8) were randomly assigned to the 12-week intervention program (five training sessions) or a waiting list control group. The intervention consisted of basic information, group activities, and homework assignments. Participants in the intervention group demonstrated higher levels of happiness, pleasure, and engagement after completion of the program. Baseline levels of psychometric intelligence moderated the intervention effectiveness (greater effects for those higher in reasoning, vocabulary, and general intelligence). There were no effects for the big five personality traits. Finally, increases in positive affect before and after the homework assignment were associated with greater levels of happiness after the program. The relevance of these findings for the development of new programs is discussed.
Soy food intake and breast cancer survival.

CONTEXT Soy foods are rich in isoflavones, a major group of phytoestrogens that have been hypothesized to reduce the risk of breast cancer. However, the estrogen-like effect of isoflavones and the potential interaction between isoflavones and tamoxifen have led to concern about soy food consumption among breast cancer patients. OBJECTIVE To evaluate the association of soy food intake after diagnosis of breast cancer with total mortality and cancer recurrence. DESIGN, SETTING, AND PARTICIPANTS The Shanghai Breast Cancer Survival Study, a large, population-based cohort study of 5042 female breast cancer survivors in China. Women aged 20 to 75 years with diagnoses between March 2002 and April 2006 were recruited and followed up through June 2009. Information on cancer diagnosis and treatment, lifestyle exposures after cancer diagnosis, and disease progression was collected at approximately 6 months after cancer diagnosis and was reassessed at 3 follow-up interviews conducted at 18, 36, and 60 months after diagnosis. Annual record linkage with the Shanghai Vital Statistics Registry database was carried out to obtain survival information for participants who were lost to follow-up. Medical charts were reviewed to verify disease and treatment information. MAIN OUTCOME MEASURES Total mortality and breast cancer recurrence or breast cancer-related deaths. Cox regression analysis was carried out with adjustment for known clinical predictors and other lifestyle factors. Soy food intake was treated as a time-dependent variable. RESULTS During the median follow-up of 3.9 years (range, 0.5-6.2 years), 444 deaths and 534 recurrences or breast cancer-related deaths were documented in 5033 surgically treated breast cancer patients. Soy food intake, as measured by either soy protein or soy isoflavone intake, was inversely associated with mortality and recurrence. The hazard ratio associated with the highest quartile of soy protein intake was 0.71 (95% confidence interval [CI], 0.54-0.92) for total mortality and 0.68 (95% CI, 0.54-0.87) for recurrence compared with the lowest quartile of intake. The multivariate-adjusted 4-year mortality rates were 10.3% and 7.4%, and the 4-year recurrence rates were 11.2% and 8.0%, respectively, for women in the lowest and highest quartiles of soy protein intake. The inverse association was evident among women with either estrogen receptor-positive or -negative breast cancer and was present in both users and nonusers of tamoxifen. CONCLUSION Among women with breast cancer, soy food consumption was significantly associated with decreased risk of death and recurrence.

Assigning Function Labels to Unparsed Text

In this paper, we propose a novel solution to the problem of assigning function labels to syntactic constituents. This task is a useful intermediate step between syntactic parsing and semantic role labelling. What distinguishes our proposal from other attempts in function or semantic role labelling is that we perform the learning of function labels at the same time as parsing. We reach state-of-the-art performance both on parsing and function labelling. Our results indicate that function label information is located in the lower levels of the parse tree, and that, similarly to other function and semantic labelling results, the main difficulty lies in distinguishing constituents that bear a function label from constituents that do not.
Sonographic findings in muscle strain injury: clinical and MR imaging correlation.

Both sonography and magnetic resonance imaging were performed in 57 patients with clinically suspected strain injury in lower extremity muscles. Sonography demonstrated normal findings in nine patients (16%), hyperechoic infiltration in 31 patients (54%), mass in nine patients (16%), and compound lesions of infiltration and mass in eight patients (14%). Clinically grade 2 lesions ranged from small infiltration to large compound lesions on both sonography and magnetic resonance imaging. Hyperechoic infiltration was not demonstrated on T1‐weighted magnetic resonance images and with less than 50% cross‐sectional muscle involvement. The mass and compound lesions were ascertained to be moderate or severe injury because the masses of the lesions had obvious hemorrhage or hematoma on magnetic resonance images.
Neuropeptide release from airways of young and fully‐grown rabbits

Nerve growth factor (NGF), a neurotrophin that regulates neuronal development, enhances production of neuropeptides that control airway caliber including substance P (SP). Little is known about the developmental interplay between neurotrophins and neuropeptides. Our goal was to assess release of NGF, SP, and vasoactive intestinal peptide (VIP) from tracheal segments of young (2‐week‐old) and fully‐grown (13‐week‐old) rabbits, and ascertain location of neuropeptides in airways with mechanical denudation of epithelium and immunohistochemistry. After electrical field stimulation of nerves, bath solutions were collected and immunoassays performed to quantify NGF, SP, and VIP release. There were significant decreases in NGF, SP, and VIP release from airways in 13‐ versus 2‐week‐old rabbits. There were also significant decreases in SP and VIP release from denuded versus normal tissues at 2 weeks of age. A similar pattern for SP was seen in 13‐week‐old rabbits. Immunohistochemistry demonstrated increased neuropeptides in airways from younger rabbits. Although SP was seen in the epithelium and submucosal nerves in the younger group, it was localized to the latter location in fully‐grown rabbits. VIP was seen in only submucosal nerves at both ages. Thus, release of NGF, SP, and VIP with neural stimulation decreases in rabbit tracheal segments with age. Decreases in SP with maturation and epithelial denudation appear related in part to decreases in epithelial SP with growth. However, decreases in VIP that occur normally and with epithelial denudation are not explained by location of VIP within the epithelium. The epithelium may be a source of factors that inhibit release of neuropeptides. Pediatr Pulmonol. 2006; 41:1242–1249. © 2006 Wiley‐Liss, Inc.
Baton: a service manager for better sustaining agent coordination in smart spaces

Purpose – Smart spaces are open complex computing systems, consisting of a large variety of cooperative smart things. Central to building smart spaces is the support for sophisticated coordination among diverse smart things collaborating to accomplish specified tasks. Multi‐agent systems are often used as the software infrastructures to address the coordination issue in smart spaces. However, since agents in smart spaces are dynamic, resource‐bounded and have complicated service dependencies, current approaches to coordination in multi‐agent systems encounter new challenges when applied in smart spaces. The purpose of this paper is to address these issues.Design/methodology/approach – The paper presents Baton, a service management system to explicitly resolve the particular issues stemming from smart spaces when coordinating agents. Baton is designed as a complement to coordination approaches in multi‐agent systems with a focus on mechanisms for service discovery, composition, request arbitration and depe.
Psychometric Properties of a Portuguese Version of the Revised Sociosexual Orientation Inventory

Sociosexuality refers to the propensity to engage in sexual relations without closeness or commitment, varying from a restricted to an unrestricted orientation. The aim of this research was to scrutinise the psychometric properties of a Portuguese version of the revised Sociosexual Orientation Inventory (SOI-R; Penke & Asendorpf, 2008). The study included 549 persons (50% women) aged 18–75 years (M = 38.73; SD = 17.77). The psychometric properties of the SOI-R were analysed by means of confirmatory factor analysis, internal consistency, and validity. Confirmatory factor analysis showed the expected three-factor structure of the measure. The SOI-R presented adequate internal consistency. Women were less unrestricted than men in all facets of sociosexuality. This Portuguese version of the SOI-R seems to be reliable and valid for evaluating sociosexuality in a Portuguese-speaking population, and can be utilised for experimental and applied works. The significance and limitations of the results are discussed.
GDC: An efficient tag recommendation algorithm

Diversifying the query results is an effective approach to obtain an user's underlying query information. Tag as an important recommendation information has drawn more and more attentions, which is also extensively exploited in SN(Social Network). The results generated by the current algorithms often ignore diversity in the recommended results, which seriously affecting the user's experience. In this paper, we address the problem of diversified coverage based tag recommendation. To our best knowledge, it is first proposed in the context of tag recommendation. Since the NP-hardness of the problem, a greedy based diversified coverage tag recommendation algorithm, namely GDC, is proposed. First, it constructs a semantic similarity graph based on the local and global tag co-occurrence matrices, which improves the recommendation accuracy by incorporating both the user's interests and the popularity of tags. Further, GDC recursively searches the MIDS (Minimum Independent Dominating Set) in an efficient manner together with an effective pruning rule. The experiments conducted on the real datasets of MovieLens and Last.fm show that the proposed GDC improve the diversity significantly.
THE NORM OF EVEN-HANDEDNESS IN SURVEYS AS IN LIFE*

Results from four past split-ballot experiments are drawn on to show that a norm of even-handedness operates in surveys much as it does in the rest of life: contextual linkage leads to greater consistency in the treatment of two competing parties than would occur if each were considered in isolation. A fifth experiment, developed to test this theory, provides partial confirmation but also evidence that the norm can create effects in one direction only. In addition, a sixth experiment is reviewed which emphasizes the fact that a presumed needfor psychological consistency is too vague a description of the Jorces at work. Only where consistency receives normative definition and direction does the context effect occur. Finally, an attempt is made to specify types of persons most susceptible to the context effect, but further evidence will be needed in order to achieve more complete understanding on this point.
Demographic and psychosocial factors associated with appointment attendance among HIV-positive outpatients

Abstract Non-adherence to medical regimens is a critical threat to HIV-infected individuals. Persons living with HIV/AIDS must adhere to their outpatient medical appointments to benefit from continually improving HIV care regimens. The primary purpose of the present study was to identify individual and psychosocial characteristics associated with HIV-related medical appointment non-attendance. One hundred seventy eight adult participants attending the Outpatient Adult HIV/AIDS Immunology Clinic at Jackson Memorial Hospital (JMH) in Miami, Florida participated in the study. Scheduled and missed appointments obtained retrospectively over a 12-month period indicated that medical appointment non-attendance was a significant problem. Overall, 27.9% of scheduled appointments were missed during the study period. Young age and limited family support were predictors of non-attendance. These findings support those of others and highlight targeted intervention efforts to reduce appointment non-attendance among persons living with HIV/AIDS.
Dynamic user profiling approach for services discovery in mobile environments

User profiling is commonly used to support personalization as well as to enhance usability of software systems by automatically adapting to the needs and preferences of their users. This paper presents an approach to dynamically update mobile users' profiles so that they can be provided with appropriate services while moving from one location to another. We propose an XML generic user profile structure that is dynamically updatable as the user experiences new services and that can be used by different software systems and applications. The proposed profile learning mechanism makes use of clustering users with a subset of similar attributes to predict appropriate services to a new user, and segmenting services with a subset of similar usage to discover and recommend new services that might be of interests to a mobile user. We demonstrated the feasibility of our approach by presenting a case study in tourism where tourists are assisted during their travels by providing them with services and information of interest. The tourist preferences and her/his current location are incorporated in the proactive formulation of suggestions on the tourist mobile devices about nearby points of interests (e.g. museums, restaurants.).
Comparative evaluation of 0.75% ropivacaine with clonidine and 0.5% bupivacaine with clonidine in infraclavicular brachial plexus block

Background: Infraclavicular brachial block with coracoids approach has gained popularity because of consistent bony landmarks and less chances of vascular puncture and pneumothorax. Aim: The aim of this study was to evaluate the effect of adding clonidine to bupivacaine or ropivacaine on the onset and duration of sensory and motor block and duration of analgesia in infraclavicular block. Materials and Methods: In a prospective randomized double-blind study, 60 patients of 18-65 years were randomly divided in to two groups of 30 each. Infraclavicular block was performed with 30 ml of 0.75% ropivacaine + 150 μg clonidine in group R and 30 ml of 0.5% bupivacaine + 150 μg clonidine in group B and were compared for onset and duration of sensory and motor block, postoperative analgesia, side-effects and complications. Results: Significant differences were observed in the time for onset of sensory block (5.80 ± 5.12 min in group R and 4.87 ± 1.46 min in group B, P < 0.05); onset of motor block (11.37 ± 2.66 min in group R and 9.60 ± 1.78 min in group B, P < 0.05); duration of sensory and motor block (10.07 ± 0.91 and 9.03 ± 0.89 h in group R and 12.50 ± 1.14 and 10.67 ± 1.18 h in group B respectively, P < 0.01) and duration of analgesia (15.30 ± 1.39 h in group R and 18.07 ± 1.66 h in group B). No significant difference was observed in hemodynamics, sedation, side-effects and complications. Statistical Analysis: Variables were compared using Chi-square test for nonparametric data and Student′s t-test for parametric data. Conclusion: Addition of clonidine to bupivacaine lead to early onset and prolonged duration of sensory and motor block with prolonged analgesia as compared to the addition of clonidine to ropivacaine.
