Comparing Election Methods Where Each Voter Ranks Only Few Candidates

Election rules are formal processes that aggregate voters' preferences, typically to select a single winning candidate. Most of the election rules studied in the literature require the voters to rank the candidates from the most to the least preferred one. This method of eliciting preferences is impractical when the number of candidates to be ranked is large. We ask how well certain election rules (focusing on positional scoring rules and the Minimax rule) can be approximated from partial preferences collected through one of the following procedures: (i) randomized—we ask each voter to rank a random subset of ℓ candidates, and (ii) deterministic—we ask each voter to provide a ranking of her ℓ most preferred candidates (the ℓ-truncated ballot). We establish theoretical bounds on the approximation ratios and complement our theoretical analysis with computer simulations. We find that it is usually better to use the randomized approach.
Unsupervised Scalable Representation Learning for Multivariate Time Series

Time series constitute a challenging data type for machine learning algorithms, due to their highly variable lengths and sparse labeling in practice. In this paper, we tackle this challenge by proposing an unsupervised method to learn universal embeddings of time series. Unlike previous works, it is scalable with respect to their length and we demonstrate the quality, transferability and practicability of the learned representations with thorough experiments and comparisons. To this end, we combine an encoder based on causal dilated convolutions with a novel triplet loss employing time-based negative sampling, obtaining general-purpose representations for variable length and multivariate time series.
On function field Mordell-Lang and Manin-Mumford

We present a reduction of the function field Mordell-Lang conjecture to the function field Manin-Mumford conjecture, in all characteristics, via model theory, but avoiding recourse to the dichotomy theorems for (generalized) Zariski structures. In this version 2, the quantifier elimination result in positive characteristic is extended from simple abelian varieties to all abelian varieties, completing the main theorem in the positive characteristic case. In version 3, some corrections are made to the proof of quantifier elimination in positive characteristic, and the paper is substantially reorganized.
Thermal contact resistance in carbon nanotube enhanced heat storage materials

Solid-liquid phase change is one of the most favorable means of compact and economical heat storage in the built environment. In such storage systems, the vast available solar heat is stored as latent heat in the storage materials. Recent studies suggest using sugar alcohols as seasonal heat storage materials for their large storage capacity, moderate melting point, and evident supercooling effects. However, the heat transfer in such materials is sluggish and hence carbon structures are proposed to enhance their overall heat conductivity. In this work, we focus on sugar alcohol - carbon nanotube system, analyze the heat transfer in the radial direction of the nanotube using molecular dynamics simulations. The thermal contact resistance is calculated using Nos´e-Hoover dynamics and is found dependent on the diameter of the tubes. We validate our results using water - nanotube simulations. Then the simulation method is extended to sugar alcohol - nanotube systems.
Gynaecomazia in a HIV, Hepatitis B and C affected middle aged male: a case report

Gynaecomazia is defined as a benign proliferation of male breast tissue. Asymptomatic gynaecomazia is very common and has a trimodal age distribution, occurring in neonatal, pubertal, and elderly males. In Nepal, gynaecomazia comprises 2.5% of all breast lumps. It is usually caused by increased estrogen activity, decreased testosterone activity, or by the use of numerous medications and can cause considerable anxiety to the patients.
The peculiarities of gene expression of medullary breast carcinoma tumor-associated antigensin different types of breast tumors

Aim. To investigate gene expression profile of human medullary breast carcinoma's tumor-associated antigens in different histological types of breast tumors. To analyze a correlation between alterations in gene expression level and induction of immune response against the cor responding antigens. Methods. Real-time polymerase chain reaction. Results. Differential gene expression profile of 6 (RAD50, HMGN2, RBPJ, PABPC4, BRAP, DEK) medullary breast carcinoma tumor- associated antigens have been revealed in breast tumors of different histological types. Correlation between changes in tumor-associated antigens gene expression level and induction of immune response has not been found. Conclusions. The genes of human medullary breast carcinomatumor-associatedantigenswithdifferentialexpression pro-fileindifferenthistologicaltypesofbreast tumors are potential diagno- stic markers of breast cancer. Alteration of tumor-associated antigens gene expression level is not a prelude to an immune response against their corresponding protein products.
Beyond the “Toolkit Approach”: Arts Impact Evaluation Research and the Realities of Cultural Policy‐Making

This article presents a reflection on the possibility and potential advantages of the development of a humanities‐based approach to assessing the impact of the arts, which attempts to move away from a paradigm of evaluation based on a one‐size‐fits‐all model usually reliant on empirical methodologies borrowed from the social sciences. A “toolkit approach” to arts impact assessment, as the article argues, demands excessive simplifications, and its popularity is linked to its perceived advocacy potential rather than to any demonstrable contribution it may make to a genuine understanding of the nature and potential effects of artistic engagement. The article also explores the relationship between research, advocacy and the actual realities of policy‐making with a view to proposing a critical research agenda for impact evaluation based on Carol Weiss’s notion of the “enlightenment” function of policy‐oriented research. In particular, the article attempts to highlight the contribution that cultural policy scholars working within the humanities could make to this area of policy research.
Perceived Arsenic‐Related Mortality Risks for Smokers and Non‐Smokers

Prolonged ingestion of arsenic in drinking water can increase the risks of dying of lung and bladder cancer, particularly for smokers. In a survey of arsenic hotspots in the United States, we elicited individuals' subjective mortality risks related to the presence of arsenic in drinking water. Using this data, we address whether smokers perceive mortality risks from this source differently from non‐smokers. We find that those who have smoked at some point in their life have significantly higher perceived arsenic mortality risks than those who have never smoked, on average. We also find that the sample group of current smokers has higher average perceived arsenic mortality risks than those who have quit smoking. We model the decision to treat water for arsenic and find some evidence that current smokers are less likely to engage in this mitigating behavior than are ex‐smokers or non‐smokers even though their perceived risk is higher. We infer that smokers are either less risk averse or have a higher rate of time preference than non‐smokers and ex‐smokers.
Higher-order models versus direct hierarchical models: g as superordinate or breadth factor?

Intelligence research appears to have overwhelmingly endorsed a superordinate (higher-order model) conceptualization of g, in comparison to the relatively less well-known breadth conceptualization of g, as represented by the direct hierarchical model. In this paper, several similarities and distinctions between the indirect and direct hierarchical models are delineated. Based on the re-analysis of five correlation matrices, it was demonstrated via CFA that the conventional conception of g as a higherorder superordinate factor was likely not as plausible as a first-order breadth factor. The results are discussed in light of theoretical advantages of conceptualizing g as a first-order factor. Further, because the associations between group-factors and g are constrained to zero within a direct hierarchical model, previous observations of isomorphic associations between a lower-order group factor and g are questioned.
Impacts of Information Technology on Mass Customization Capability of Manufacturing Plants

Purpose – The impact of information technology (IT) on mass customization (MC) capability has been implied in the literature but seldom subjected to empirical examination. This study theoretically relates four types of IT applications with MC capability and empirically examines these relationships. Design/methodology/approach – This study identifies four types of IT that potentially support MC capability, including product configurator IT, new product development IT, manufacturing IT, and supplier collaboration IT. Drawing on organizational information processing theory, this study associates the four IT types with a manufacturer’s MC capability. A structural equation model is tested using survey data collected from a sample of manufacturing plants that focus on product customization. Findings – The empirical results indicate that three of the four IT types either strongly or marginally support a manufacturer’s MC capability. Research limitations/implications – Data used in this study are cross-sectional in nature. Also, a set of refined IT measures should be developed in future studies. Practical implications – The paper identifies managerial opportunities for investing in IT to support or enhance MC capability.Originality/value – The study is one of the first efforts to empirically examine the impact of multiple types of IT applications on MC capability. The study also develops a classification framework of IT applications in manufacturing plants.
Full trispectrum in single field DBI inflation

We compute the tree-level connected four-point function of the primordial curvature perturbation for a fairly general minimally coupled single field inflationary model, where the inflaton's Lagrangian is a general function of the scalar field and its first derivatives. This model includes K inflation and DBI inflation as particular cases. We show that, at the leading order in the slow-roll expansion and in the small sound speed limit, there are two important tree-level diagrams for the trispectrum. One is a diagram where a scalar mode is exchanged and the other is a diagram where the interaction occurs at a point, i.e. a contact interaction diagram. The scalar exchange contribution is comparable to the contact interaction contribution. For the DBI-inflation model, in the so-called equilateral configuration, the scalar exchange trispectrum is maximized when the angles between the four momentum vectors are equal and in this case the amplitude of the trispectrum from the scalar exchange is 1 order of magnitude higher than the contact interaction trispectrum.
Associations of Insertion-deletion Polymorphism of Angiotensin-converting Enzyme with the Risk of Preeclampsia Development among Pregnant Women in Central Russia

Objectives: The associations of the insertion-deletion angiotensin-converting enzyme (I/D ACE) genetic polymorphism with the risk of preeclampsia development were studied. Materials and Methods: The study group included 350 women: 100 women with a physiological pregnancy and 250 pregnant women with preeclampsia. All women underwent the typing of I/D polymorphism of the ACE gene. Results: The pregnant women with the preeclampsia of the 2nd degree of severity showed the lowest concentration of genotype II ACE (11.00%) as compared with pregnant women without preeclampsia (25.00%; odds ratio [OR] = 0.37; P = 0.017; Pcor = 0.051). With the preeclampsia of the 3rd degree of severity, the minimum frequency of the genotype II ACE (7.27%) and the maximum frequency of the allele D ACE (62.73%) are recorded among pregnant women as compared with the pregnant women without preeclampsia (25.00%; OR = 0.24; P = 0.01; Pcor = 0.03 and 49.50%, OR = 1.72, P = 0.03, respectively). Conclusions: Thus, the D ACE allele is associated with the risk of preeclampsia development of the 3rd degree of severity, and the ACE genotype II is a protective factor of preeclampsia development of the 2nd and the 3rd degree of severity.
Gelatin extraction from the indigenous Pangasius catfish bone using pineapple liquid waste

Gelatin extraction from fish bone has traditionally involved hydrogen chloride and/or sodium hydroxide during pre-treatment. However, these chemicals have begun to be abandoned because of their associated safety and environmental issues. Several studies have looked at the use of citric acid as a safer alternative in fish bone gelatin extraction. The aim of this research was to extract gelatin from the bone of Pangasius catfish with pineapple liquid waste. The extraction was performed in two steps: pre-treatment followed by main extraction at various times (24–56 h) and temperatures (45–75°C). Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was used as a confirmation test and showed a band for gelatin at ~120 kDa. Gelatin yields were calculated as the ratio of weight of dried gelatin to the total weight of fish ossein . The results indicated that pineapple liquid waste can be used for fish bone gelatin extraction. The recommended conditions for extraction of fish bone gelatin using pineapple liquid waste are 56 h of pre-treatment and 5 h of main extraction at a temperature of 75°C. The gelatin yield was 6.12% and the protein concentration 4.00 g/100 g.
GENDER CONTRIBUTION TO HIGHLAND TEA FIELD AGRONOMIC PRACTICES IN TARABA STATE, NIGERIA

Agbongiarhuoyi AE, Daniel MA (2010) Gender contribution to highland tea field agronomic practices in Taraba state, Nigeria. Int. J. Sustain. Crop Prod. 5(4), 71-75. Tea cultivation is a labour demanding activity especially in most of the farm operations. These operations are carried out by both male and female farmers. There is no empirical data on the specific gender roles of tea agronomic practices in Nigeria. The objective of this study was to assess the contribution of gender in tea field farming activities in Taraba State during 2008. One hundred respondents were selected using multi-stage sampling technique. Out of five blocks, one block was purposively chosen and five villages were purposively selected. In the next stage, 50 male farmers and 50 female farmers from the villages with 20 from each village were randomly selected and interviewed using structured questionnaire. Results were analyzed using descriptive statistics and chi-square. About 57% of the respondents were between 30-40 years. Their highest literacy level was Islamic education (28%) meaning they attended Islamic school while (47%) had 12-18 years of farming experience. About 48% of the respondents had an annual output of 1000–1200 kg/ha value at $266.54-398.81 at $0.15/kg of tea. In tea field establishment practices, 39.0-78.3% of the adult males carried out land clearing, pegging, digging of planting holes, transplanting of seedlings, fertilizer application and pruning while 37.6-42.3% of the adult females were involved in weeding, harvesting/plucking as well as fertilizer application. The boys and girls participated least in field practices. Males tend to contribute more in field management practices than their female counterparts in tea production. However, females contribute actively in plucking; this is very vital in tea income generation. Over 90% of the respondents obtained information on tea practices from the Nigeria Beverages Production Company (NBPC) Limited and 98% from CRIN. Gender had a significant effect on tea field practices (p<0.01).

A Spitzer View of Mon OB1 East/NGC 2264

We present Spitzer 3.6, 4.5, 5.8, 8.0, and 24 micron images of the Mon OB1 East giant molecular cloud, which contains the young star forming region NGC 2264, as well as more extended star formation. With Spitzer data and 2MASS photometry, we identify and classify young stellar objects (YSOs) with dusty circumstellar disks and/or envelopes in Mon OB1 East by their infrared-excess emission and study their distribution with respect to cloud material. We find a correlation between the local surface density of YSOs and column density of molecular gas as traced by dust extinction that is roughly described as a power law in these quantities. NGC 2264 follows a power law index of ~2.7, exhibiting a large YSO surface density for a given gas column density. Outside of NGC 2264 where the surface density of YSOs is lower, the power law is shallower and the region exhibits a larger gas column density for a YSO surface density, suggesting the star formation is more recent. In order to measure the fraction of cloud members with circumstellar disks/envelopes, we estimate the number of diskless pre-main sequence stars by statistical removal of background star detections. We find that the disk fraction of the NGC 2264 region is 45%, while the surrounding more distributed regions show a disk fraction of 19%. This may be explained by the presence an older, more dispersed population of stars. In total, the Spitzer observations provide evidence for heterogenous, non-coeval star formation throughout the Mon OB1 cloud.
Aggressiveness of Fusarium langsethiae isolates towards wheat, barley and oats in an in vitro leaf assay

Aggressiveness of Fusarium langsethiae isolates towards wheat, barley and oats in an in vitro leaf assay Fusarium langsethiae has been identified as the primary producer of HT-2 and T-2 in European cereals. HT-2 and T-2 are considered as two of the most potent trichothecenes mycotoxins and a public health concern in Europe. There is currently no legislation on HT-2 and T-2, however, there is a discussion limit of 500 μg kg-1 in unprocessed oats, 200 μg kg-1 for oat products and 50 μg kg-1 for infant food. There are limited data regarding F. langsethiae's pathogenicity and mycotoxin production, but it is evident that its behaviour deviates from traditional trichothecene-producing Fusarium species. This experiment was aimed at assessing the aggressiveness (measured by lesion length) of 20 different F. langsethiae isolates on wheat, barley and oats using an in vitro detached leaf assay. There was a significant (P<0.001) difference between lesion lengths formed by different F. langsethiae isolates used. Isolate Fl/2004/17(a) caused the shortest lesion on all cereals and this was significantly (P<0.001) different from that caused by isolate Fl/0/08/009/1 which caused the longest lesion on all cereals used. A highly significant difference (P<0.001) was also observed between lesions on the different cereals (wheat, barley and oats). Lesions on oats were the longest, followed by barley with wheat showing the shortest lesions.
Quality of Commercial Flavoured Oils and Seed Oils Using a Widespread Analytical Protocol

Commercial flavoured olive and olive-sunflower oils and seed oils with particular nutritional properties (e.g. linseed, safflower, sunflower, sesame and rice oils) were analysed using a widespread analytical protocol to have information on their quality and chemical composition. The protocol involved traditional determinations (free acidity, peroxide value, UV and VIS spectrophotometric indices, and fatty acid composition) along with 1 H and 13 C NMR analyses. Most of flavoured olive oils turned out to be lampante olive oils and not extra virgin as declared in the label on the bottle. In the case of olive-sunflower oils only a minor fraction of olive oil was revealed although these products are particularly expensive and the presence of olive oil is emphasized on the label. In some seed oils, refinement processes, not indicated on the bottle, were highlighted. Some compounds characteristic of specific seed oils were identified in the 1 H spectra.

Estimates of genetic parameters and expected gains from selection of yield traits in sugarcane families

It is essential to have basic information on the genetic nature of variation of various metric traits in plantation crops for the proper planning of breeding strategies. The objective of this paper was to estimate the variability for five yield traits in sugarcane (Saccharum spp.) families. Eighteen controlled pollination families were evaluated in a randomized complete block trial having 16 plants per linear plot at Jau Development and Research Station (DDD/APTA/SAA), in Jau city, Sao Paulo State, Brazil. In the second year, families were assessed and harvested six months after the first ratoon, and evaluated for the following characters: stalk height, stalk diameter, average Brix, stalk number and stalk weight. The results showed highly significant (p<0.01) genetic differences among families for most traits. The genotypic variance component accounted for 4.27, 3.55, 15.87, 3.32 and 51.68% of the phenotypic variance for stalk height, stalk number, stalk diameter, stalk weight and average Brix, respectively. Heritabilities at individual plant level for the above traits were 56.57, 76.59, 67.40, 72.73 and 54.11%, respectively. Negative significant genotypic and phenotypic correlations were found between Brix and stalk height (r g = -0.78**, r p = -0.56**) and stalk diameter (r g = -0.81**, r p = -0.75**). Selecting the best two families out of 18 families would result in a genetic gain of 4.92% and 10.82% for stalk height and stalk diameter, respectively. The best two selected individual seedlings within each family would result in a genetic gain of 18.61% and 16.94% with a total gain of 23.57 % and 27.76 % for these two traits, respectively.
