Published: May 2015

It is always attractive and challenging to explore the intricate behavior data and uncover people's motivations, preference and habits, which can greatly benefit many tasks including link prediction, item recommendation, etc. Traditional work usually studies people's behaviors without time information in a static or discrete manner, assuming the underlying factors stay invariant in a long period. However, we believe people's behaviors are dynamic, and the contributing factors including the social influence and personal preference for behaviors are
varying continuously over time.
Such continuous dynamics convey important knowledge about people's behavior patterns; ignoring them would lead to inaccurate models.

In this work, we address the continuous dynamic modeling of temporal behaviors. To model the fully continuous temporal dynamics of behaviors and the underlying factors, we propose the DP-Space, a dynamic preference probability space, which can capture their smooth variation in various shapes over time with flexible basis functions. Upon that we propose a generative dynamic behavior model, ConTyor, which considers the temporal item-adoption behaviors as joint effect of dynamic social influence and varying personal preference over continuous time. We also develop effective inference methods for ConTyor and present its applications.
We conduct a comprehensive experimental study using real-world datasets to evaluate the effectiveness of our model and the temporal modeling. Results verify that ConTyor outperforms existing state-of-the-art static and temporal models in behavior predictions. Moreover, in our detailed study on temporal modeling, we show that temporal modeling is superior to static approaches and modeling over continuous time is further better than that over discrete time. We also demonstrate that the ancient behavior data can still become important and beneficial if modeled well.
Viral marketing meets social advertising

Published: May 2015

Social advertisement is one of the fastest growing sectors in the digital advertisement landscape: ads in the form of promoted posts are shown in the feed of users of a social networking platform, along with normal social posts; if a user clicks on a promoted post, the host (social network owner) is paid a fixed amount from the advertiser. In this context, allocating ads to users is typically performed by maximizing click-through-rate, i.e., the likelihood that the user will click on the ad. However, this simple strategy fails to leverage the fact the ads can propagate virally through the network, from endorsing users to their followers.
In this paper, we study the problem of allocating ads to users through the viral-marketing lenses. We show that allocation that takes into account the propensity of ads for viral propagation can achieve significantly better performance. However, uncontrolled virality could be undesirable for the host as it creates room for exploitation by the advertisers: hoping to tap uncontrolled virality, an advertiser might declare a lower budget for its marketing campaign, aiming at the same large outcome with a smaller cost.
This creates a challenging trade-off: on the one hand, the host aims at leveraging virality and the network effect to improve advertising efficacy, while on the other hand the host wants to avoid giving away free service due to uncontrolled virality. We formalize this as the problem of ad allocation with minimum regret, which we show is NP-hard and inapproximable w.r.t. any factor. However, we devise an algorithm that provides approximation guarantees w.r.t. the total budget of all advertisers. We develop a scalable version of our approximation algorithm, which we extensively test on four real-world data sets, confirming that our algorithm delivers high quality solutions, is scalable, and significantly outperforms several natural baselines.

Abstract
In the present study, ZP method for lean meat content (LMC) evaluation in pig carcasses was tested. The experiment was carried out on 141 pigs selected from animals delivered for slaughter to the SKIBA S.A. meat plant located in Chojnice. The selected pigs originated from three country regions, and differed in respect of subcutaneous fat thickness (7-32 mm), carcass weight (60-120 kg) and sex (50% gilts and 50% castrated males). The main result of the study was a rectilinear regression equation for lean meat content assessment. Two linear measurements were used in the equation, i.e. backfat thickness measured on sacral vertebra and thickness of the muscle layer located between the beginning of the cross section of gluteus medius and back edge of the spinal cord. The evaluation error RMSEP was 2.33% and did not exceed the limit defined in EU regulations. Based on the Commission Decision 2011/506/EU the ZP method was approved to be used for pig carcass grading in Poland. A special measuring template was developed for the industrial use of the ZP method.
Pig behaviour in relation to weather conditions – a review
Authors: Olczak Katarzyna , Nowicki Jacek , Klocek Czesław 
Published: May 2015

Abstract
Weather conditions (temperature, humidity, solar radiation, air pressure, wind strength, wind direction and precipitation) have a significant impact on the behaviour of farm animals. Pigs have developed a wide range of thermoregulatory behaviours that are particular for this species. With increases in temperature the most characteristic behaviour for pigs is decreased activity and increased wallowing in wet surfaces. In addition to this, rooting and wallowing are highly influenced by temperature and humidity. The lack of possibility to express these behaviours leads to development of stereotypies. Interestingly, low temperatures do not increase the use of shelter if not in combination with wind or precipitation. Furthermore, wild pigs build stronger nests in severe conditions. Also, resting behaviour and reproduction may be disturbed by high temperatures. There is a negative impact of foehn wind on boars’ libido and semen parameters.

Published: May 2015

Abstract
The aim of this study was monitoring the iodine concentration in Polish consumer milk in the years 2011-2012. The test material used in this study consisted of consumer UHT pasteurized milk with extended shelf life. Six randomly selected cartons of milk with different fat content (from 0.5% to 3.2%) were each purchased from large-sized stores located in 16 cities during the summer and in 13 cities during the cow’s winter feeding period. In total, 167 milk samples were collected. During the summer season, the milk’s iodine content averaged 143 μg iodine kg-1 and ranged from 103 to 196 μg iodine kg-1 (n=96 samples), with a standard deviation (SD) of ±31 and coefficient variability (CV) of 44%. During the winter season, the milk’s iodine content averaged 183 μg iodine kg-1 and ranged from 141 to 236 μg iodine kg-1 (n=77 samples), with a standard deviation (SD) of ±5 and coefficient of variability (%) (CV) of 26%. Iodine levels in Polish consumer milk increased from the last monitoring (2007-2008) from 100 to 143 μg iodine kg-1 in the summer season, and from 147 to 183 μg iodine kg-1 in the winter season (increases of 47% and 24%, respectively).

Published: May 2015

Abstract
The aim of this study was to investigate, under conditions similar to commercial broiler production, the effect of the herbal extract blend (HE) at a quantity of 1 g per kg feed (200 mg of each herbal extract, Allium sativum, Salvia officinalis, Echinacea purpurea, Thymus vulgaris and Origanum
vulgare), used individually or in combination with mannan oligosaccharide (MOS; 1 g per kg feed) or chitosan (3 ml containing 2% deacetylated chitin per kg feed) on the performance parameters of broiler chickens, the results of the slaughter analysis, litter moisture and the number of oocysts excreted in feces. The experiment was conducted on 4,500 broiler chickens of both sexes kept in straw-bedded pens. Chickens were randomly assigned to 5 experimental treatments with 5 replicates (pens) of 180 birds. The experimental design included negative and positive (diclazuril, 1 mg per kg feed) control groups. The examined herbal extract blend used individually during natural exposure to the coccidia improved, compared to the negative control diet, the performance parameters to a greater extent than coccidiostat, lowered the litter moisture content and reduced the oocyst output. Combined dietary supplementation with a herbal extract blend of chitosan or mannan oligosaccharide did not result in further improvement.

Published: May 2015

Abstract
Meiotic gynogenetic development of the rainbow trout (Oncorhynchus mykiss, Walbaum 1792) was induced in the course of egg activation performed by the UV-irradiated homologous and heterologous (European grayling Thymallus thymallus Linnaeus, 1758) spermatozoa. To recover diploidy in the gynogenetic zygotes, activated eggs were subjected to the high pressure shock in order to inhibit extrusion of the second polar body. Gynogenetic rainbow trout progeny hatched from the eggs activated by the irradiated rainbow trout and grayling milt with similar hatching rates of 28.19% and 29.22%, respectively. However, gynogenetic rainbow trout produced with grayling semen had shown lower survival than gynogenotes provided with the homologous spermatozoa during two years of rearing. Viable hybrids are not produced between rainbow trout and grayling which ensured that fish obtained in this experiment were true gynogenetic progenies. A Robertsonian polymorphism characteristic for the rainbow trout from the studied strain was also observed among the gynogenetic specimens that exhibited diploid chromosome number ranging from 58 to 62 and stable chromosome arm number (FN= 104). No radiation-induced fragments of the paternal chromosomes were observed in the gynogenetic individuals. Fish produced in both experimental variants were genotypic (XX) and phenotypic (gonads) females. The results confirmed that the gynogenetic protocol used in the present research is an efficient means of producing all-female gynogenetic rainbow trout stocks.
Cognition-based multimedia classifier learning
Authors: Kuo Jenny Yichun 
Published: May 2015

Abstract
In a classifier language like Chinese, all the noun phrases with numerals or demonstratives must go with classifiers, for example, liǎng zhī bǐ 兩枝筆 ‘two CL pen.’ Classifiers vary depending on the nouns. This poses a big challenge for learners of Chinese as second language. Cognition-based multimedia and paper materials for Chinese material classifiers were developed and proved to be effective for learners of Chinese as a second language. The experimental group (N = 15) used the multimedia program and the control group (N= 20) received the same information on paper. Both groups made significant progress after a 10-week treatment. The results suggest cognitive principles are helpful for classifier learning in either multimedia or paper format.
Demand-Side Factors Associated with the Purchase of Long-Term Care Insurance

Published: May 2015

Abstract
Demand-side barriers are known to be important toward explaining the limited purchase of private long-term care insurance (LTCI). In this study, we examine several factors associated with the demand for LTCI including the availability of less costly substitutes (e.g., Medicaid, family), consumer information, and risk perception. Using buyer surveys from 2000, 2005, and 2010, our results suggest that, among individuals not eliminated through medical underwriting, consumer risk perception and the presence of lower cost, imperfect substitutes are strongly associated with the limited purchase of LTCI. These factors were also predictive of the generosity of coverage purchased. If policymakers seek to stimulate demand for LTCI, new public policies might include Medicaid reform, integrating LTCI with Medicare Advantage plans, enhanced LTCI offerings through employers, and targeted informational campaigns.
Health Care Provision in a Swiss Urban Walk-In-Clinic. Is Advanced Nursing Practice a Solution for a New Model in Primary Care? / Gesundheitsversorgung in einer städtischen Walk-In-Praxis in der Schweiz. Ist Advanced Nursing Practice ein neues Modell in der Grundversorgung?
Authors: Kambli Katrin , Flach Daniel , Schwendimann René , Cignacco Eva 
Published: May 2015

Abstract
Background: Changing demographic and economic factors are producing serious challenges to Switzerland’s primary care providers: meeting the population’s growing needs will require redevelopment and reorganization. Large-scale community-based care can be expanded via alternative care models, including walk-in-clinics (WIC) stuffed by interdisciplinary teams, with Advanced Practice Nurses (APNs) playing key roles in the treatment of minor complaints.
Aims: To reveal the proportion of adult patients within five exemplary diagnostic groups (respiratory tract infections, earaches, hearing impairments, urinary tract infections and wounds) who could be treated by APNs in a Swiss urban WIC in order to develop a future model of multidisciplinary collaboration between APN and physicians.
Methods: A retrospective data analysis was performed on WIC’s medical records. Reflecting seasonal variations, a one-month patient data sample was collected for each of four consecutive seasons (July and October 2010, January and April 2011). Data analyses included calculations of frequencies of individual diagnoses and of diagnostic groups.
Results: Of a combined sample of 5,130 patient consultations, 53% (n=2,733) fit within the scope of APN competencies. The most common diagnoses concerned minor wounds (24%; n=1,240) and upper respiratory tract infections (18%; n=926).
Conclusion: Based on this study’s results, we conclude that assigning APNs to primary care clinics would contribute a meaningful new professional role to Switzerlands healthcare system. Further research will be necessary to evaluate the effects of such implementation on inter-professional collaboration and patient outcomes.
Amniotic fluid LPCAT1 mRNA correlates with the lamellar body count
Authors: Welch Robert A. , Shaw Michael K. , Welch Kathryn C. 
Published: May 2015

AbstractLysophosphatidylcholine acyltransferase 1 (LPCAT1) is required in the biosynthesis of pulmonary surfactant. This short communication describes our assessment of LPCAT1 mRNA levels in human amniotic fluid. We found a direct correlation between LPCAT1 mRNA copies and the amniotic fluid lamellar body count (LBC). This finding corroborates an association between LPCAT1 and surfactant phospholipid biosynthesis in humans. It may provide a model for future research in perinatal medicine.
Modeling spatial batting ability using a known covariance matrix
Authors: Cross Jared , Sylvan Dana 
Published: May 2015

AbstractIn baseball, heat maps, which visualize a batter’s ability across regions in and around the strike zone, play an important role in baseball commentary and scouting reports. We represent the stochastic process underlying these heat maps as a spatial Gaussian field with isotropic covariance. Spatial interpolation (kriging) relies on the assumption of a known covariance function, but in reality the parameters of the covariance are typically estimated from the data. Our simulation study, based on a known covariance function, helps to understand and explain the spatial dependence of the process and allows us to produce improved heat maps.
Throughput Maximization with S-graph Framework using Global Branching Tree
Authors: Holczinger Tibor , Orosz Ákos 
Published: May 2015

Abstract
Majozi and Friedler [3] developed the first approach for throughput maximization, which has no need for the optimal number of time points a-priori. The feasibility of a sequence of subproblems is examined with guided search driven S-graph based approach. Although, the approach has proved to be efficient for several problems [1], it can be developed further to increase the size of addressable cases.
In the original approach, a branching tree is generated for each subproblem separately, even though these trees can have significantly large overlaps. The presented approach exploits this redundancy to reduce the computational needs for industrial scale problems.
Sensor Fusion for Intrusion Detection With Sensor Networks
Authors: Koszteczky Bence , Simon Gyula 
Published: May 2015

Abstract
A sensor fusion algorithm is proposed, which can be used to fuse measurements from a distributed sensor network, containing inexpensive, easily deployable and energy efficient magnetic sensor devices. The sensor measurements are collected and transferred to a central base station, where the sensor fusion is performed, using the sensor location. The algorithm provides location, direction, and speed information about the detected vehicles. The paper describes the sensor technology and the fusion method, and the performance of the system is illustrated by real test measurements.
Chromosomal abnormalities in a decade of prenatal testing at the Department of Obstetrics and Pathology of Pregnancy Medical University of Lublin
Authors: Krzyżanowski Arkadiusz , Gęca Tomasz , Kwiatek Maciej , Kwaśniewska Anna 
Published: May 2015

Abstract
Introduction. Chromosomal abnormalities, one of the leading causes of pregnancy complications, attract attention of both researchers and clinicians. They use two approaches to identify chromosomal abnormalities, namely screening and diagnostic tests. Ultrasonography is a very reliable screening and diagnostic tool, but the only way to determine if there are any chromosomal defects in the fetus, is performing one of invasive diagnostics tests chorionic villus sampling (CVS), cordocentesis or amniocentesis. Unfortunately, these invasive diagnostic procedures carry a potentially high risk of complications. Using amniocentesis means a procedure-related miscarriage risk at a rate of about 0.5-1%.
Aim. The aim of this paper was to present our own experience, results in performing amniocentesis and a review of the literature.
Material and methods. During a 10-year period 237 mid-trimester, transabdominal amniocenteses were performed.
Results. The follow-up revealed one spontaneous abortion within seven days after the procedure. Premature delivery occurred in fourteen cases (two of them with chromosomal abnormalities). No neonatal deaths related to amniocentesis were noticed. Chromosomal abnormalities were detected in 33 patients.
Conclusions. In the group with chromosomal abnormalities the main indications to perform amniocentesis were: improper ultrasound scan and the first trimester biochemical, noninvasive screening tests. This is a proof that modern, non-invasive procedures like the first-trimester ultrasound scan and biochemical tests should be made available to every pregnant woman and not only to mothers’ aged >35 years or those with a poor obstetrics history.

Abstract
Introduction. Increased suicide rates, both among adults and adolescents, have been seen in Poland over recent years.
Aim. The aim of the study was to determine the prevalence of self-injury, suicide ideation, plans and attempts in adolescents aged 13 to 19 years.
Material and methods. The study encompassed the total number of 6883 individuals aged 13 to 19 years, 69% of them being girls and 31% - boys. All respondents lived in Lubelskie Province. The research was conducted using a questionnaire designed by the authors.
Results. In the group composed of 6883 adolescents living in Lublin Province, suicide ideation was reported by 47.65% of the respondents, suicide plans by 32.35%, suicide attempts were carried out by 10% of adolescents and self-injury by 24.91% of the respondents aged 13 to 19 years.
Conclusions. The greatest prevalence of suicide ideation, plans and attempts, as well as self-injuries, were recorded in the group of adolescents aged 17. The adolescents living in the urban areas are more likely to inflict self-injury than those living in rural areas. Furthermore, adolescents with suicidal tendencies, e.g. attempting suicide and self-injury, are more prone to alcohol and substance abuse. It needs emphasizing that many adolescents with suicidal tendencies, compared against those who did not carry them out, have past experience of psychological, physical and sexual violence in the family, have been raised by a single parent or in families, where one of the parents abused alcohol.

Streszczenie
Wstęp: Choroba zwyrodnieniowa stawów biodrowych stanowi u osób starszych jedną z głównych przyczyn dysfunkcji narządu ruchu oraz jest najczęstszą przyczyną wykonywania endoprotezoplastyki stawów biodrowych u osób po 65 r.ż. Postęp medycyny i rehabilitacji pozwala osobom starszym na utrzymanie wysokiej sprawności funkcjonalnej oraz samodzielności w wykonywaniu czynności życia codziennego.
Cel pracy: Przedstawienie najczęstszych problemów z zakresu czynności dnia codziennego po zabiegu endoprotezoplastyki stawu biodrowego u pacjentów geriatrycznych.
Materiał i metody: Zbadano 189 pensjonariuszy placówek opieki instytucjonalnej w wieku 70-98 lat (MEAN 81,77; SD 6,5), w tym 123 kobiety i 66 mężczyzn. Do oceny funkcjonalnej zastosowano skalę oceny podstawowych czynności życia codziennego ADL oraz skalę złożonych czynności życia IADL. Wykonano stratyfikację na wiek (Gr I: 70-79 r.ż., Gr II- >80 r.ż.). Analizę statystyczną wykonano w programie STATISTICA v10. Weryfikację hipotez podjęto na podstawie testu Manna-Whitneya przy założeniu α=0.05.
Wyniki: Wszystkie badane osoby miały największe problemy w ADL w zakresie czynności samodzielnego kąpania się (43%) oraz kontrolowaniu wydalania moczu i stolca (66,66%). W skali IADL największe trudności badani mieli z gospodarowaniem pieniędzmi (71%), ponad połowa nie była w stanie wyjść poza odległość spaceru (54%). Po wprowadzeniu stratyfikacji na wiek, wynik główny ADL nie różnił się istotnie pomiędzy grupami (5 pkt. vs 5 pkt., p>0.05), istotne statystycznie różnice wykryto w skali IADL pomiędzy grupami (Gr I 20 pkt vs Gr II 18pkt., p<0.05).
Wnioski: W 4 tygodnie po endoprotezoplastyce osoby objęte opieką instytucjonalną prezentują ubytki funkcjonalne w zakresie pielęgnacji. Treningi aktywności podstawowych i złożonych czynności dnia codziennego powinny być podstawowym elementem postępowania interdyscyplinarnego w geriatrii.
