Tabulation of cubic function fields via polynomial binary cubic forms

We present a method for tabulating all cubic function fields over $\mathbb{F}_{q}(t)$ whose discriminant $D$ has either odd degree or even degree and the leading coefficient of $-3D$ is a non-square in $\mathbb_{q}^*$, up to a given bound $X$ on $|D| = q^{\deg(D)}$. Our method is based on a generalization of Belabas' method for tabulating cubic number fields. The main theoretical ingredient is a generalization of a theorem of Davenport and Heilbronn to cubic function fields, along with a reduction theory for binary cubic forms that provides an efficient way to compute equivalence classes of binary cubic forms. The algorithm requires $O(q^4 X^{1+\epsilon})$ field operations when $D$ has odd degree, and $O(q^5 X^{1+\epsilon})$ when $D$ has even degree. It performs quite well in practice. The algorithm, examples and numerical data for $q=5,7,11,13$ are included.
The importance of quality requirements in software platform development-a survey

This paper presents a survey where some quality requirements that commonly affect software architecture have been prioritized with respect to cost and lead-time impact when developing software platforms and when using them. Software platforms are the basis for a product-line, i.e. a collection of functionality that a number of products is based on. The survey has been carried out in two large software development organizations using 34 senior participants. The prioritization was carried out using the Incomplete Pairwise Comparison method (IPC). The analysis shows that there are large differences between the importance of the quality requirements studied. The differences between the views of different stakeholders are also analysed and it is found to be less than the difference between the quality requirements. Yet this is identified as a potential source of negative impact on product development cost and lead-time, and rules of thumb for reducing the impact are given.
When Fiction becomes Fact: Effect of Reverse Product Placement on Consumer Attitudes

ABSTRACT This exploratory study investigates the persuasive effects of reverse product placement (RPP)—subsequent commercialization of fictional brands from entertainment media into real world products—comparing it with product placement (PP). Persuasion Knowledge Model and Attribution theory were applied to frame hypotheses of effects on brand attitudes along with the constraining effect of skepticism. A mixed test design revealed presence of persuasion knowledge, recognition of persuasive intent, and negative effect of skepticism for PP, but not for RPP. RPP also had a stronger, positive effect on consumer attitudes. Potential application of RPP in new product development and adoption is discussed.
Elimination of intermediate species in multiscale stochastic reaction networks.

We study networks of biochemical reactions modelled by continuous-time Markov processes. Such networks typically contain many molecular species and reactions and are hard to study analytically as well as by simulation. Particularly, we are interested in reaction networks with intermediate species such as the substrate-enzyme complex in the Michaelis-Menten mechanism. These species are virtually in all real-world networks, they are typically short-lived, degraded at a fast rate and hard to observe experimentally. We provide conditions under which the Markov process of a multiscale reaction network with intermediate species is approximated in finite dimensional distribution by the Markov process of a simpler reduced reaction network without intermediate species. We do so by embedding the Markov processes into a one-parameter family of processes, where reaction rates and species abundances are scaled in the parameter. Further, we show that there are close links between these stochastic models and deterministic ODE models of the same networks.
See you at the match: Motivation for sport consumption and intrinsic psychological reward of premier football league spectators in South Africa

Orientation: Local football contributes significantly to the social- and economic welfare of South Africa through its spectators. Understanding the motives and experiences of football spectators could provide opportunities for capitalising on football as revenue stream feeding the South African economy. Research purpose: To investigate how motives for sport consumption predict intrinsic psychological reward of South African premier league football spectators. Motivation for the study: Sport - particularly football - is an untapped resource for stimulating economic development and growth through its consumers. Spectators, who often experience their investment in the sport as deeply rewarding and meaningful, should participate more frequently in purchasing products or services associated with the sport. Through understanding the motives for sport consumption of South African premier league football spectators and the impact of these motives on intrinsic psychological reward experiences, football clubs are able to provide a targeted experience or service to spectators in order to further stimulate economic growth. Research design, approach and method: A census sample of 806 football spectators attending various matches at a football stadium in Soweto was drawn. A cross-sectional research design was implemented. This research was exploratory and descriptive. Structural equation modelling was implemented to assess the factor structures of the constructs, to confirm composite reliability of the measures and to assess the structural paths between the variables. Main findings: A predictive model for intrinsic psychological rewards (life satisfaction and meaning) through the motivation for sport consumption (individual – and game related factors) was confirmed. It was further established that motivation for sport consumption is significantly positively a) related to and b) associated with the experience of intrinsic psychological reward by South African football spectators. Practical/managerial implications: Football clubs should tailor spectator experiences around both individual and game related spectator motives in order to develop experiences associated with intrinsic psychological reward. Contribution/value-add: The study contributes to consumer psychology research relating to the motives associated with the consumption of football within South Africa.
The Preferences of University Instructors Regarding Research and Teaching Duties

The author assesses the preferences of the faculty and teaching staff at Russian universities with regard to their research and teaching duties. She investigates how they structure their work schedule and academic productivity, and how universities with and without special status differ. The study is based on data from two international studies conducted in Russia and other countries: International Academic Profession (1991–93) and Changing Academic Profession (2007–12). In Russia, most university instructors prefer teaching to research, in contrast to the preferences of academics in many other countries. The distribution of the preferences of instructors at institutions with “research university” status is no different from that of instructors at institutions without special status. Although the research workload of instructors who prefer to conduct research is greater and the tasks they perform are less routine, they experience less stress and have greater job satisfaction. The author concludes that the distribution of instructors' preferences reflects the peculiarities of the higher education system in the USSR and the Russian Federation, including the focus of its universities on teaching, the allocation of research functions to institutions that are separate from universities, and the poor funding of universities in general and their research functions in particular.
Relationship Between Depression and Life Event in Early Adolescents: A Cross-lagged Regression Analysis

Objective: To explore the causality between life event and depression in early adolescents and its dynamic change.Methods: A total of 598 middle school students from Nanjing were measured with Adolescent Self-rating Life Events Check List and Children's Depression Inventory-Short Version once every year for three years.Results: For total samples,life event,interpersonal relationship and study pressure at Grade 1 predicted depression at Grade 2;depression at Grade 2 predicted life event,interpersonal relationship and study pressure at Grade 3.There was significant gender difference in the causality between life event,interpersonal relationship,study pressure and depression in early adolescents.For girls,life event and interpersonal relationship at Grade 1 and Grade 2 predicted depression at Grade 2 and Grade 3,respectively.For boys,depression at Grade 2 predicted life event,interpersonal relationship and study pressure at Grade 3.Conclusion: There is a dynamic transformation in the causality between depression and life event in early adolescents.Depression is not always the outcome variable,sometimes depression is the cause of life event.
Trait Intellect Predicts Cognitive Engagement: Evidence from a Resource Allocation Perspective

Trait Intellect, one of the two ‘aspects’ of the broader Openness/Intellect ‘domain’, predicts performance on a range of cognitive tasks including tests of intelligence and working memory. This has been explained in terms of the tendency for high–Intellect individuals to explore, or engage more effortfully with, abstract information. This theoretical perspective can be framed in the language of Resource Allocation Theory, in terms of high–Intellect individuals allocating more of their available cognitive resources to abstract cognitive tasks. In two experiments (total N = 160), we examined the relation between Intellect and cognitive engagement during a primary word–search task under conditions of both high and low secondary cognitive load. Both experiments revealed that high–Intellect individuals were more vulnerable to the impact of the secondary cognitive load on primary task performance. This suggests that, under low secondary load, such individuals were indeed allocating more of their available cognitive resources to the primary task. These results held after controlling for trait Openness, trait Industriousness (an aspect of Conscientiousness) and a measure of working memory capacity (N–back task). Our findings provide novel support for the cognitive mechanisms proposed to underlie trait Intellect. Copyright © 2016 European Association of Personality Psychology
User perceptions of and willingness to pay for household container-based sanitation services: experience from Cap Haitien, Haiti

Household-level container-based sanitation (CBS) services may help address the persistent challenge of providing effective, affordable sanitation services for which low-income urban households are willing to pay. Little is known, however, about user perceptions of and demand for household CBS services. This study presents the results of a pilot CBS service programme in Cap Haitien, Haiti. One hundred and eighteen households were randomly selected to receive toilets and a twice-weekly collection service. After three months, changes in these households’ satisfaction with their sanitation situation, along with feelings of pride, modernity and personal safety, were compared to 248 households in two comparison cohorts. Following the service pilot, 71 per cent of participating households opted to continue with the container-based sanitation service as paying subscribers. The results from this study suggest that, in the context of urban Haiti, household CBS systems have the potential to satisfy many residents’ desire for safe, convenient and modern sanitation services.
Building a free French wordnet from multilingual resources

This paper describes automatic construction a freely-available wordnet for French (WOLF) based on Princeton WordNet (PWN) by using various multilingual resources. Polysemous words were dealt with an approach in which a parallel corpus for five languages was word-aligned and the extracted multilingual lexicon was disambiguated with the existing wordnets for these languages. On the other hand, a bilingual approach sufficed to acquire equivalents for monosemous words. Bilingual lexicons were extracted from Wikipedia and thesauri. The results obtained from each resource were merged and ranked according to the number of resources yielding the same literal. Automatic evaluation of the merged wordnet was performed with the French WordNet (FREWN). Manual evaluation was also carried out on a sample of the generated synsets. Precision shows that the presented approach has proved to be very promising and applications to use the created wordnet are already intended.
Feto-Maternal : Communication in Broiler Chickens (Gallus gallus domesticus)

Bird incubation is a natural phenomenon that balances the needs of the parents for nourishment with the needs of the fetus for heat provision and protection. In this context, any means of communication between the fetus and the parents would have an adaptive value. The aim of the study was to investigate whether putative means of fetomaternal communication would correlate to physiological changes caused by environmental alterations. Oxygen consumption was used to measure fetal well being and six independent variables associated with fetal vocalizations and fetal movements were used to evaluate their potential for communicating the fetus statu quo. Broiler fetuses (Gallus gallus domesticus) of three developmental stages (day 18, internally pipped and externally pipped) were challenged by a stepwise reduction in ambient temperature down to 30oC. A linear drop in oxygen consumption in response to lowered temperatures was found in all three developmental stages indicating that the fetus was affected by the temperature changes. No differences correlating with temperature variations were found in any of the variables associated with fetal vocalization. Fetal vocalizations are consequently not used to communicate the thermal status of the fetus. Movement occurrence, movement intensity and ventilation frequency, however, followed a “maximum peak” trend, with a highest response at the third temperature interval (35.0-35.5oC). Considering that the lower limit of optimal development is between 35-36oC, the results suggest that fetal movements can be of potential use to the incubating parent to assess the well-being of the fetus.
[Comparison of an immature platelet fraction and reticulated platelet in liver cirrhosis].

BACKGROUND The main causes of thrombocytopenia in cirrhosis are thought to be platelet destruction and the reduction of thrombopoietin (TPO) expression in the liver. Immature platelet fraction (IPF) has been measured by a fully automated analyzer (Sysmex XE-2100, Japan) as reticulated platelet (RP), which is reflected with thrombopoiesis in bone marrow. In this study, we tried to compare the percentage of IPF (IPF) with that of RP (RP) in patients with liver cirrhosis (LC) and controls. METHODS We compared IPF to RP in 72 liver cirrhosis patients and 30 healthy normal controls. RP was stained with acridine orange, followed by FC500 (Beckman Coulter, USA) analysis and the IPF was identified by flow cytometry with the use of a nucleic acid specific dye in the reticulocyte channel on the Sysmex XE-2100 (TOA Medical Electronics Co., Ltd., Japan). RESULTS IPF value in the healthy control was 2.2% (1.7-5.2). RP and IPF were significantly higher in the patients with liver cirrhosis (P<0.05). IPF appeared to be correlated with RP (y=0.19x+3.35, r=0.34, P<0.05). In ROC for diagnosis of LC, IPF was significantly more useful than RP. CONCLUSIONS This results show that a rapid, inexpensive automated method for measuring the IPF is feasible and should become a standard parameter in evaluating reticulated platelets.
Object and Event Extraction for Video Processing and Representation in On-Line Video Applications

As the use of video becomes increasingly popular, and wide spread through, for instance, broadcast services, Internet, and security-related applications, providing means for fast, automated, and effective techniques to represent video based on its content, such as objects and meanings, are important topics of research. In a surveillance application, for instance, object extraction is necessary to detect and classify object behavior, and with video databases, effective retrieval must be based on highlevel features and semantics. Automated content representation would significantly facilitate the use and reduce the costs of video retrieval and surveillance by humans. Most video representation systems are based on low-level quantitative features or focus on narrow domains. There are few representation schemes based on semantics; most of these are context-dependent and focus on the constraints of a narrow application and they lack, therefore, generality and flexibility. Most systems assume simple environments, for example, without object occlusion or noise. The goal of this thesis is to provide a stable content-based video representation rich in terms of generic semantic features and moving objects. Objects are represented using quantitative and qualitative low-level features. Generic semantic features are represented using events and other high-level motion features. To achieve higher applicability, content is extracted independently of the type and the context of the input video. The proposed system is aimed at three goals: flexible content representation, reliable stable processing that foregoes the need for precision, and low computational cost. The proposed system targets video of real environments such as those with object occlusions and artifacts. To achieve these goals, three processing levels are proposed: video enhancement to estimate and reduce noise, video analysis to extract meaningful objects and their spatio-temporal features, and video interpretation to extract context-independent semantics such as events. The system is modular, and layered from low-level to middle-level to high-level where levels exchange information. The reliability of the proposed system is demonstrated by extensive experimentation on various indoor and outdoor video shots. Reliability is due to noise adaptation and due to correction or compensation of estimation errors at one step by processing at subsequent steps where higher-level information is available. The proposed system provides a response in real-time for applications with a rate of up to 10 frames per second on a shared computing machine. This response is achieved by dividing each processing level into simple but effective tasks and avoiding complex operations.
Pulmonary Rehabilitation Outcomes after Single or Double Lung Transplantation in Patients with Chronic Obstructive Pulmonary Disease or Interstitial Lung Disease

Background: Pulmonary rehabilitation (PR) following lung transplantation (LTx) has been shown to be effective with regard to exercise capacity and health-related quality of life (HRQL). However, outcome data is limited with respect to LTx as a population. Differences concerning the effects of PR in patients with single LTx (SLTx) or double LTx (DLTx) have not been studied yet. Objectives: The aim was to compare possible differences concerning PR outcomes between SLTx and DLTx. Methods: In a retrospective analysis (period: 1997-2016), data from 722 patients with either chronic obstructive pulmonary disease (COPD; SLTx: n = 129, FEV1 51 ± 17% pred.; DLTx: n = 204, FEV1 74 ± 20% pred.) or interstitial lung disease (ILD; SLTx: n = 135, FVC 58 ± 18% pred.; DLTx: n = 254, FVC 63 ± 18% pred.) after LTx were included. All patients underwent a specialized inpatient PR program. The data of the 6-minute walk distance (6MWD) and HRQL (physical [PCS] and mental [MCS] component summary of the SF- 36 questionnaire) were analyzed. Results: Independently from the procedure and pretransplant diagnosis, patients significantly (p < 0.05) improved the 6MWD without any differences between SLTx and DLTx (COPD: SLTx: +109 ± 68 m, DLTx: +117 ± 82 m; ILD: SLTx: +115 ± 80 m, DLTx: +132 ± 77 m). The PCS (COPD: SLTx: +9 ± 9 points, DLTx: +7 ± 9 points; ILD: SLTx: +6 ± 9 points, DLTx: +9 ± 9 points) and MCS (COPD: SLTx: +8 ± 15 points, DLTx: +7 ± 15 points; ILD: SLTx: +10 ± 13 points, DLTx: +8 ± 12 points) also improved significantly without any group differences. Conclusions: LTx patients with a pretransplant diagnosis of COPD or ILD all benefitted significantly and with clinical relevance with regard to exercise capacity and HRQL from an inpatient PR performed within 1 year postoperatively. PR outcomes were similar regardless of SLTx or DLTx.
Amphotericin B and Fluconazole, a Potent Combination Therapy for Cryptococcal Meningitis

ABSTRACT We evaluated the antifungal activities of amphotericin B, fluconazole, and flucytosine, alone and in combination, in a murine model of cryptococcal meningitis. The objectives were to determine the greatest antifungal effects achievable with these drugs alone or in combination. Meningitis was established in male BALB/c mice weighing 23 to 25 g by intracerebral injection of Cryptococcus neoformans. Treatment was started on day 2. Amphotericin B was tested at 0.3 to 1.3 mg/kg of body weight/day by slow intravenous injection. Fluconazole at 10 to 40 mg/kg/day and flucytosine at 20 to 105 mg/kg/day were administered in the sole source of drinking water. The mice were killed at 16 days, and the numbers of fungal colonies in the brain were quantified. The association between the response and the dose combination was evaluated by local nonparametric response surface methods; 99% confidence intervals were used to evaluate the antifungal effects. Ninety-five percent of the mice treated with amphotericin B at 0.5 mg/kg survived to the end of the experiment, regardless of the fluconazole or flucytosine dose used. The greatest activity was seen with amphotericin B plus fluconazole with or without flucytosine. However, the addition of flucytosine did not increase the antifungal activity. Given the widespread availability of amphotericin B and fluconazole and the relative safety profile of fluconazole compared to that of flucytosine, the full potential of this two-drug combination deserves further evaluation.
