Object-oriented software architecture recovery using a new hybrid clustering algorithm

In order to recover high-level software architecture from existing systems, we define Weighted Directed Class Graph(WDCG) to represent object-oriented software in this paper, which not only reflects static information of lowest level composition of software but also reflects dynamic information of software running. A new hybrid clustering algorithm based on hierarchical clustering and partition clustering is proposed for recovering high-level software architecture from WDCG. Four metrics are introduced to measure the effect of the new clustering algorithm for software architecture recovery. Experimental results show that our algorithm performs best in terms of software clustering quality, authoritativeness and extremity of cluster distribution.
An Efficient Dispersal Storage Scheme Based on Ring-LWE and NTT

We propose a novel dispersal storage scheme based on the ring learning with errors (Ring-LWE) problem. Our main technical contribution is a new systematic erasure code, called SNTT, to solve the problem of applying Ring-LWE in dispersal storage. SNTT is based on the number theoretic transform (NTT). To the best of our knowledge, SNTT is the first work that applies NTT to guarantee data availability. Analysis and experiments show that our new scheme with proper configurations outperforms the state of the art in encoding/decoding speed. Furthermore, we show that SNTT can also be used to optimize performance of existing schemes.
Individual investing in the familiar and the unfamiliar

Individual investors are faced with thousands of stocks from which to select from. Yet they often sell and then repurchase the same stock. Similar to Bernartzi’s (2001) findings in the context of employee allocations of their 401(k) plans to their company’s stock, I find that repurchases are driven by the interaction of investor preference for familiar stocks and extrapolation of prior roundtrip trade returns. There is no evidence that the repurchasing strategy outperforms a buy and hold strategy. I attribute the sub-optimality of repurchases to commission costs and under-diversification of portfolios, which are magnified for households repurchasing at higher frequencies.
Modeling of animal movement by AR process and effect of predictability of the behavior on perception of animacy and intentionality

We perceive animacy even on a simple dot traveling across a screen based on its movements. Research studies have pointed out several features of movement that are assumed to induce the perception of animacy; however, validations and discussions about these features are still insufficient. Meanwhile, other studies indicate that the perception of the intentionality is a prerequisite for the perception of animacy but these perceptions have not been differentiated clearly in the literature. In this study, we conduct an experiment with human participants to clarify the differences between animacy and intentionality in terms of the predictability of behavior. First, we model the behavior of goldfish using an autoregressive process and create several types of movies of a white dot moving on a black background where we change the fluctuation levels of its velocity and its rotation. The movies are presented to human participants and they are asked to chase the white dot using a pen tablet so that the predictability of the behavior can be quantified. The participants are also asked to rate the animacy and the intentionality of the moving dot. Our results reveal a negative correlation between the perception of animacy and intentionality.
Efficient analysis of magnetostatic surface waves in printed and suspended ferrite loaded strip lines

This paper analyzes the guidance of magnetostatic surface waves (MSSW) by a metallic strip printed on a ferrimagnetic slab or on a dielectric/ferrimagnetic structure (suspended configuration) in the frame of the magnetostatic approach. An integral spectral domain analysis (SDA) is used for this purpose. Shielding upper and/or lower ground planes are also considered. Some interesting new physical effects, such as backward and complex MSSWs in the suspended configuration are reported. Good agreement with previously published experimental and computed results confirms the validity of our approach.
Mite and cockroach sensitisation in patients with allergic rhinitis in the Free State.

BACKGROUND Studies in patients with allergic rhinitis living in the Free State have showed grass pollens to be the predominant allergens, with house-dust mite sensitisation being less prevalent than in the coastal areas and a low rate of sensitisation to the storage mite Lepidoglyphus destructor. No studies have been conducted on sensitisation to the other storage mites, spider mites or cockroaches. We aimed to determine the prevalence of sensitisation to various house-dust mites, storage mites, spider mites and cockroaches in patients with allergic rhinitis living in the Free State. METHODS Fifty consecutive patients with allergic rhinitis attending the ear, nose and throat clinic at Universitas Hospital underwent skin-prick testing and/or ImmunoCAP RAST testing for common aero-allergens, house-dust mites, storage mites, spider mites and cockroaches. RESULTS Forty-six per cent of patients were sensitised to one of the house-dust mites, with house mite sensitisation being significantly more common in patients who had previously lived at the coast. Storage mites were not common aero-allergens, while 46% of patients were sensitised to the spider mite Tetranychus urticae. Blatella germanica was the cockroach species to which patients were most commonly found to be sensitised on ImmunoCAP RAST testing, with 38% of patients being sensitised to this aero-allergen. CONCLUSIONS House-dust mites, T. urticae and the cockroach B. germanica appear to be important aero-allergens in the Free State. Storage mite sensitisation is not common.
A modified Mediterranean dietary intervention for adults with major depression: Dietary protocol and feasibility data from the SMILES trial

Background: The SMILES trial was the first randomized controlled trial (RCT) explicitly designed to evaluate a dietary intervention, conducted by qualified dietitians, for reducing depressive symptomatology in adults with clinical depression. Objectives: Here we detail the development of the prescribed diet (modified Mediterranean diet (ModiMedDiet)) for individuals with major depressive disorders (MDDs) that was designed specifically for the SMILES trial. We also present data demonstrating the extent to which this intervention achieved improvements in diet quality. Methods: The ModiMedDiet was designed using a combination of existing dietary guidelines and scientific evidence from the emerging field of nutritional psychiatric epidemiology. Sixty-seven community dwelling individuals (Melbourne, Australia) aged 18 years or over, with current poor quality diets, and MDDs were enrolled into the SMILES trial. A retention rate of 93.9 and 73.5% was observed for the dietary intervention and social support control group, respectively. The dietary intervention (ModiMedDiet) consisted of seven individual nutrition counselling sessions delivered by a qualified dietitian. The control condition comprised a social support protocol matched to the same visit schedule and length. Results: This manuscript details the first prescriptive individualized dietary intervention delivered by dietitians for adults with major depression. Significant improvements in dietary quality were observed among individuals randomized to the ModiMedDiet group. These dietary improvements were also found to be associated with changes in depressive symptoms. Discussion/Conclusion: The ModiMedDiet, a novel and individually tailored intervention designed specifically for adults with major depression, can be effectively implemented in clinical practice to manage this highly prevalent and debilitating condition.

Does self-affirmation following ego depletion moderate restrained eaters’ explicit preferences for, and implicit associations with, high-calorie foods?

Objective: The difficulty for chronic dieters (i.e. restrained eaters) in regulating their food intake is a conflict between two apparently incompatible goals: eating enjoyment and weight control. The latter goal consistently relies on the deployment of cognitive resources, and very often on a significant amount of self-control. This study investigated whether self-affirmation might counteract the effect of ego depletion on restrained eaters’ motivation to consume high-calorie foods. Design: Participants (N = 183) were assigned to one of four conditions in a 2 × 2 (Ego depletion × Self-Affirmation) experimental design and were subsequently exposed to images of high- and low-calorie foods. Main outcome measures: Participants completed tasks assessing their implicit and explicit preferences for high vs. low-calorie foods, along with a measure of the perceived self-control required to resist foods. Results: Results indicated that, following ego depletion, self-affirmation facilitated restrained eaters’ perceptions of self-control and led to lower explicit preferences for high-calorie foods. This pattern was not apparent for implicit preferences. Conclusion: Self-affirmation interventions may be capable of restoring self-control resources among restrained eaters. Pointers for future research and practical applications are discussed.
Genes, Environment, and Orofacial Clefting: N-Acetyltransferase and Folic Acid

Nonsyndromic orofacial clefting has been the subject of intense studies, both genetic and epidemiological. The findings have frequently been controversial because of lack of reproducibility. Mouse models provide the potential both for genetic and environmental uniformity. We have chosen to study the role of genetic susceptibility to teratogen-induced orofacial clefting, using 2 drugs (dilantin and corticosteroid) and 1 nondrug teratogen (6-aminonicotinamide). The strongest single genetic influence we have found is N-acetyltransferase 2. Our recent work and that of others suggest that the influence of this locus is mediated through alterations in folate metabolism. Our results support epidemiological findings in humans and possibly implicate altered cytosine methylation, potentially caused by environmental factors, at least in the A/J model.
Measuring the Gap Between FPGAs and ASICs

This paper presents experimental measurements of the differences between a 90-nm CMOS field programmable gate array (FPGA) and 90-nm CMOS standard-cell application-specific integrated circuits (ASICs) in terms of logic density, circuit speed, and power consumption for core logic. We are motivated to make these measurements to enable system designers to make better informed choices between these two media and to give insight to FPGA makers on the deficiencies to attack and, thereby, improve FPGAs. We describe the methodology by which the measurements were obtained and show that, for circuits containing only look-up table-based logic and flip-flops, the ratio of silicon area required to implement them in FPGAs and ASICs is on average 35. Modern FPGAs also contain "hard" blocks such as multiplier/accumulators and block memories. We find that these blocks reduce this average area gap significantly to as little as 18 for our benchmarks, and we estimate that extensive use of these hard blocks could potentially lower the gap to below five. The ratio of critical-path delay, from FPGA to ASIC, is roughly three to four with less influence from block memory and hard multipliers. The dynamic power consumption ratio is approximately 14 times and, with hard blocks, this gap generally becomes smaller

We consider some aspects of the global evolution problem of Hamiltonian homogeneous, anisotropic cosmologies derived from a purely quadratic action functional of the scalar curvature. We show that models can isotropize in the positive asymptotic direction and that quadratic diagonal Bianchi IX models do not recollapse and may be regular initially. Although the global existence and isotropization results we prove hold quite generally, they are applied to specific Bianchi models in an attempt to describe how certain dynamical properties uncommon to the general relativity case, become generic features of these quadratic universes. The question of integrability of the models is also considered. Our results point to the fact that the more general models are not integrable in the sense of Painlevé and for the Bianchi IX case this may be connected to the validity of a BKL oscillatory picture on approach to the singularity in sharp contrast with other higher order gravity theories that contain an Einstein term and show a monotonic evolution towards the initial singularity.
The HLA A*0201–restricted hTERT540–548 peptide is not detected on tumor cells by a CTL clone or a high-affinity T-cell receptor

Tumor-associated human telomerase reverse transcriptase (hTERT) is expressed in >85% of human tumors but not in most normal cells. As a result, this antigen has received considerable attention from those interested in cancer immunotherapy. Specifically, there has been strong interest in MHC class I–associated peptides derived from hTERT because these are expressed on the cell surface and thus may enable the targeting of tumor cells. Much of this interest has focused on peptide 540–548, ILAKFLHWL, which was predicted to exhibit the strongest binding to the common HLA A*0201 presenting molecule. The hTERT540–548 peptide is currently being assessed in therapeutic vaccination trials; however, there is controversy surrounding whether it is naturally processed and presented on the surface of neoplastic cells. Here, we generate two highly sensitive reagents to assess the presentation of hTERT540–548 on tumor cells: (a) a CD8+ CTL clone, and (b) a recombinant T-cell receptor (TCR) that binds with picomolar affinity and a half-life exceeding 14 h. This TCR enables the identification of individual HLA A2-hTERT540–548 complexes on the cell surface. The use of both this TCR and the highly antigen-sensitive CTL clone shows that the hTERT540–548 peptide cannot be detected on the surface of tumor cells, indicating that this peptide is not a naturally presented epitope. We propose that, in future, rigorous methods must be applied for the validation of peptide epitopes used for clinical applications. [Mol Cancer Ther 2007;6(7):2081–91]
Acute psychotic reactions in Caribbean-born patients

Synopsis A prospective study of patients with religious delusions identified 24 West Indian and West African patients. Those who had none of Schneider's first-rank symptoms of schizophrenia (principally West Indians) differed from those who did by virtue of early religious commitment, life-long religious experiences, an acute admission precipitated by social events, a greater chance of having their diagnosis changed, less than 10 different PSE syndromes, the absence of ‘twentieth-century’ delusions, and the presentation of malevolent witchcraft as the sole explanation of the episode. It is suggested that this group can usefully be considered as demonstrating an acute psychotic reaction of the type previously described in Africa and the Caribbean.
Police Workforce Structures

Research has long focused on the size of police agencies, giving little attention to the composition of the workforce itself. Literature in fields such as the military, healthcare, organizational psychology, and business, highlights the importance of workforce structures in meeting both organizational and staff needs. Using data from a national survey, we examine personnel cohorts (i.e., distribution of junior, midlevel, and senior sworn staff) as an element of workforce structure in the largest, U.S. municipal police organizations. We describe the importance of cohort structures for enhancing performance (meeting both organizational and individual needs) and assess variation in cohort structures. We discuss the cohorts in light of their effects on personnel management, and highlight the importance of existing cohort structures when considering major personnel decisions such as hiring freezes, furloughs, layoffs, and buyouts. We summarize future research that could advance theory and policy regarding workforce structures in police and other criminal justice organizations.
Nest Poaching in Neotropical Parrots

Abstract: Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortality due to nest poaching in 23 studies of Neotropical parrots, representing 4024 nesting attempts in 21 species and 14 countries. We also examined how poaching rates vary with geographic region, presence of active protection programs, conservation status and economic value of a species, and passage of the U.S. Wild Bird Conservation Act. The average poaching rate across all studies was 30% of all nests observed. Thirteen studies reported poaching rates of ≥20%, and four reported rates openface> 70%. Only six studies documented no nest poaching. Of these, four were conducted on islands in the Caribbean region, which had significantly lower poaching rates than the mainland Neotropics. The other two studies that showed no poaching were conducted on the two species with the lowest economic value in our sample ( U.S. retail price). In four studies that allowed direct comparison between poaching at sites with active nest protection versus that at unprotected sites, poaching rates were significantly lower at protected sites, suggesting that active protection efforts can be effective in reducing nest poaching. In those studies conducted both before and after the passage of the U.S. Wild Bird Conservation Act, poaching rates were found to be significantly lower following its enactment than in the period before. This result supports the hypothesis that the legal and illegal parrot trades are positively related, rather than inversely related as has been suggested by avicultural interests. Overall, our study indicates that poaching of parrot nestlings for economic gain is a widespread and biologically significant source of nest mortality in Neotropical parrots.
Updated mortality study of a cohort of asbestos textile workers

Limited information is available on risk of peritoneal mesothelioma after asbestos exposure, and in general on the risk of cancer after cessation of asbestos exposure. We updated to 2013 the follow‐up of a cohort of 1083 female and 894 male textile workers with heavy asbestos exposure (up to 100 fb/mL), often for short periods. A total of 1019 deaths were observed, corresponding to a standardized mortality ratio (SMR) of 1.68 (95% confidence interval [CI]: 1.57–1.78). SMRs were 29.1 (95% CI: 21.5–38.6) for peritoneal cancer, 2.96 (95% CI: 2.50–3.49) for lung cancer, 33.7 (95% CI: 25.7–43.4) for pleural cancer, and 3.03 (95% CI: 1.69–4.99) for ovarian cancer. For pleural and peritoneal cancer, there was no consistent pattern of risk in relation to time since last exposure, whereas for lung cancer there was an indication of a decline in risk after 25 years since last exposure. The findings of this unique cohort provide novel data for peritoneal cancer, indicating that – as for pleural cancer – the excess risk does not decline up to several decades after cessation of exposure.
An Empirical Assessment of Impact of Organizational Climate on Organizational Citizenship Behaviour

Successful organizations need their employees to perform more than their usual job responsibilities and this can be possible if the environment at workplace is supportive and conducive for them. The present study is focused on organizational citizenship behaviour (OCB) and its most influencing antecedent “organizational climate”. The sample consisted of 509 respondents working in a large-scale food processing industry of Punjab. The data were collected through a structured questionnaire and were analyzed using Pearson product–moment correlation and multiple regression analysis. The findings of the study indicated a strong positive correlation between organizational climate and OCB. The results of multiple regression analysis indicated that 67.6 per cent of the variance in OCB is explained by the dimensions of organizational climate. Further, organizational climate dimensions such as supervisory support, performance feedback, clarity of organizational climate, autonomy, pressure to produce, welfare and participation are found to have a significant impact on OCB. The research provides the implications for managers to engross themselves into the activities that improve organizational climate to ensure that the desired extra-role behavioural outcomes can be met.
The determination of myocardial viability using Gd‐DTPA in a canine model of acute myocardial ischemia and reperfusion

The partition coefficient of Gd‐DTPA was thought to vary with the amount of cellular membrane damage after an acute myocardial infarction. The relationship between the partition coefficient of Gd‐DTPA (λ) and the uptake of 201TI (as a marker of tissue viability) was studied 2 h to 3 weeks after reperfusion of a 2‐h occlusion to the left anterior descending coronary artery in a canine model. Gd‐DTPA was infused as a bolus followed by a prolonged constant infusion, and this infusion protocol was optimized such that the concentration of Gd‐DTPA was directly related to λ. After this infusion, MR images of excised hearts showed regions of increased signal intensity corresponding to increased Gd‐DTPA concentration. At all time points, λ and 201TI uptake were strongly negatively correlated indicating that λ is an accurate indicator of myocardial viability. Furthermore, λ in the infarcted regions was increased relative to normal regions after 2 h of reperfusion and stayed elevated up to 3 weeks. At all time points, λ in the infarcted and normal regions were significantly different. As well, this data showed a trend that λ in infarcted regions decreased monotonically from 1 day to 3 weeks. This trend was confirmed with MR imaging by examining the change in signal intensity of in vivo images from 4 days to 3 weeks in two animals. These results suggest that MRI with Gd‐DTPA could be used to measure the extent of myocardial damage after an acute myocardial infarction.
Dimensions of Aspirations, Work Roles, and Decision-Making of Farm Husbands and Wives in Wisconsin

Dimensions of aspirations, work roles, and decision-making are delineated by the use of factor analysis. The rotated factors indicate that the instrumental-task and decision-making structure of the farm family is multidimensional. Intercorrelations of husband and wife measures indicate that there is a specialization in decision-making as well as in the performance of tasks with joint involvement in certain areas. While there is a consensus upon family goals, the value placed upon specific goals by the spouses also reflects their own interests and involvement in different areas.
