Paper or Screen -- Differences in Customer Preferences and Willingness to Pay between Traditional and Digital Content Services

The digitalization and the diffusion of connected mobile devices have urged media companies to deliver their content in digital formats such as apps. We evaluate differences in customers' preferences and willingness to pay between traditional and digital content services conducting an adaptive conjoint analysis. Within this analysis we compare subscriptions to a printed newspaper with subscriptions to the website, e-paper, smartphone app or tablet app of this newspaper. Our results show that customers still prefer the printed newspaper over any digital format. The acceptance of digital newspaper formats depends on device ownership but the website is most popular in general. Our findings have profound implications for multi-platform publishing strategies. Content providers have to examine carefully in in which situations their products might be used and which devices their potential customers own in order to choose the right formats and prices.
From situation modelling to a distributed rule-based platform for situation awareness: an ontological framework for disaster management applications

Situation-aware (SA) applications are particularly useful for disaster management. The complex nature of emergency scenarios presents challenges to the development of collaborative and distributed SA solutions. These challenges concern the whole lifecycle, from specification to implementation phases, such as how to model the reaction behavior of a detected situation and how to provide an interoperable situation notification service. In addition, treating unforeseen situations, i.e. situations not modeled at design-time, is an open topic. In this PhD research we intend to deal with these issues by proposing a framework for SA application development, which is applicable in different emergency scenarios and covers the conceptual, specification and implementation aspects, through an ontological model-driven methodology. The conceptual requirements can be addressed by adopting an appropriate foundational ontology. The specification aspects include the design of the context, the situation types of interest and the decision to be performed by the application when a situation is detected. For supporting the implementation of the SA application, we intend to improve the interoperability and performance of an existing rule-based situation notification platform, which is based on service oriented architecture and complex event processing. A separate module takes advantage of predictive analysis techniques to detect unforeseen situations. We plan to evaluate our framework with SA application prototypes and proofs-of-concept.
Implementation of a Written Protocol for Management of Central Venous Access Devices: A Theoretical and Practical Education' Including Bedside Examinations

The objectives of this study were to evaluate registered nurses' (RN) compliance with a local clinical central venous access device (CVAD) protocol after completing an educational program and to determine RNs' perception of the program. Seventy-five RNs working in hematology participated in the educational part of the program. Sixty-eight RNs were examined while changing CVAD dressings or placing a Huber needle into a port on actual patients. Sixty percent of the RNs passed the examination and reported that the program increased their knowledge. The results indicated that the educational program could be recommended for use when implementing a new clinical protocol.
A maximum power point tracking control scheme for magnetically coupled resonant wireless power transfer system by cascading SEPIC converter at the receiving side

Variation of spatial scales and load resistances have significant effects on the transmission power of magnetically coupled resonant (MCR) wireless power transfer (WPT) system. To realize maximum power transmission under arbitrary spatial scale and different load resistances, a control scheme for automatic maximum power point tracking (MPPT) operation was presented in this paper. Based on the transmission power characteristics of a two-coil WPT system with a series resonant topology, a SEPIC converter was introduced to cascade at the receiving side to achieve MPPT for MCR WPT system. Adopting perturbation and observation (P&O) method to adjust equivalent input resistance of SEPIC converter dynamically, the proposed scheme tracked the maximum transmission power operating point by matching the corresponding mutual inductance with varying spatial scales. The experimental results had shown the validity of the theoretical analysis and the feasibility of the proposed scheme.
A 120GHz in-band full-duplex PMF transceiver with tunable electrical-balance duplexer in 40nm CMOS

A 120GHz in-band full-duplex PMF transceiver with tunable electrical-balance duplexer with on-chip antenna is implemented in a 40nm bulk CMOS tech-nology. The self-interference (SI) cancellation is performed with a fully-differential transformer-based electrical-balance duplexer, resulting in a SI suppression of 30dB over a bandwidth of more than 14GHz. The insertion loss of the duplexer is less than 11dB from TX to fiber and less than 12dB from fiber to RX at a frequency of 120GHz. The balancing network impedance can tolerate load impedances from 45Ω to 93Ω and 38fF to 266fF at 120GHz. For in-band full-duplex operation, the maximum measured data rate is 6.2Gbps. The transceiver with integrated antenna occupies an area of 1.8mm × 1.53mm and has a DC power consumption of 73mW in total.
Hemorrhagic Necrosis of Pheochromocytoma Associated with Phentolamine Administration

A case of ruptured pheochromocytoma is presented, the pathophysiology discussed, and the literature reviewed. Evidence is presented that the use of alpha-adrenergic blockade in general, and phentolamine in particular, may predispose to this complication. Twelve cases of massive hemorrhagic necrosis with or without rupture were found in the literature, including the present case. Six had no operation; one survived. Six had immediate operation; 4 survived. An additional case of hemorrhage into a small pheochromocytoma following phentolamine is presented. This tumor was neither ruptured nor massively necrotic, but the case supports the hypothesis that alpha-adrenergic blockade may cause hemorrhage within the pheochromocytoma.
Acute acetaminophen ingestion does not alter core temperature or sweating during exercise in hot–humid conditions

Acute acetaminophen (ACT) ingestion has been reported to reduce thermal strain during cycling in the heat. In this study, nine active participants ingested 20 mg of ACT per kg of total body mass (ACT) or a placebo (PLA), 60 min prior to cycling at a fixed rate of metabolic heat production (ACT: 8.3 ± 0.3 W/kg; PLA: 8.5 ± 0.5 W/kg), which was equivalent to 55 ± 6% VO2max, for 60 min at 34.5 ± 0.1 °C, 52 ± 1% relative humidity. Resting rectal temperature (Tre; ACT: 36.70 ± 0.17 °C; PLA: 36.80 ± 0.16 °C, P = 0.24), esophageal temperature (Tes; ACT: 36.54 ± 0.22 °C; PLA: 36.61 ± 0.17 °C, P = 0.50) and mean skin temperature (Tsk; ACT: 34.00 ± 0.14 °C; PLA: 33.96 ± 0.20 °C, P = 0.70) were all similar among conditions. At end‐exercise, no differences in ΔTre (ACT: 1.12 ± 0.15 °C; PLA: 1.11 ± 0.21 °C, P = 0.92), ΔTes (ACT: 0.90 ± 0.28 °C; PLA: 0.88 ± 0.23 °C, P = 0.84), ΔTsk (ACT: 0.80 ± 0.39 °C; PLA: 0.70 ± 0.46 °C, P = 0.63), mean local sweat rate (ACT: 1.02 ± 0.15 mg/cm2/min; PLA: 1.02 ± 0.13 mg/cm2/min, P = 0.98) and whole‐body sweat loss (ACT: 663 ± 83 g; PLA: 663 ± 77 g, P = 0.995) were evident. Furthermore, ratings of perceived exertion and thermal sensation and thermal comfort were not different between ACT and PLA conditions. In conclusion, ACT ingested 60 min prior to moderate intensity exercise in hot–humid conditions does not alter physiologic thermoregulatory control nor perceived strain.

On optimization of CI/MC-CDMA system

This paper proposes a new model of high capacity carrier interferometry/multicarrier code division multiple access (CI/MCCDMA) system through the simultaneous support of high and low data rate transmission using odd and even subcarriers. Reduction in peak-to-average power ratio (PAPR) is achieved through the phase shift of even (odd) CI code using odd (even) sub-carriers by an amount of π/2 and odd (even) CI code using odd (even) sub-carriers by −π/2, all angles measured with respect to the orthogonal codes supporting high data rate transmission. The CI code optimization is done for further reduction in PAPR values. Specifically, assuming a frequency selective Rayleigh-fading channel, bit error rate (BER) at receiver is improved through the cancelation of MAI (multiple access interference) at subcarriers level using PIC (parallel interference cance-lation) at reduced computation cost. Finally, the system is optimized with respect to the number of subcarriers, number of users (capacity) and signal-to-noise ratio (SNR) using GAs (Genetic Algorithms) to achieve an acceptable set of values for BER, PAPR and average data rate (ADR).

Using Coh-Metrix to Analyze Chinese ESL Learners’ Writing

Scoring essays is a costly, laborious and time-consuming effort. Automated scoring of essays is a promising approach to face this challenge. Coh-Metrix is a computer tool which reports on a wide range of linguistic features and several dimensions of cohesions. It has been widely used to analyze essays written by native English speakers. However, few studies have been conducted to use Coh-Metrix for analyzing essays written by English as a Second Language (ESL) students. In this study, we analyzed the correlation between several Coh-Metrix features combined with a set of newly proposed features and the quality of essays, written by Chinese university students, both English and non-English majors. This study shows that each group of students tend to write essays that have their own signature features. The quality of essays written by English majors are highly correlated to importance of introduction, conclusion and cohesion at sentence level, while the quality of essays written by chemistry majors are highly related to mechanics errors, sentence complexity and cohesion at paragraph level.
Trophic effect of cholera toxin B subunit in cultured cerebellar granule neurons: Modulation of intracellular calcium by GM1 ganglioside

Survival of cerebellar granule cells (CGC) in culture was significantly improved in the presence of cholera toxin B subunit (Ctx B), a ligand which binds to GM1 with specificity and high affinity. This trophic effect was linked to elevation of intracellular calcium ([Ca2+]i), and was additive to that of high K+. Survival was optimized when Ctx B was present for several days during the early culture period. 45Ca2+ and cell survival studies indicated the mechanism to involve enhanced influx of Ca2+ through L‐type voltage‐sensitive channels, since the trophic effect was blocked by antagonists specific for that channel type. Inhibitors of N‐methyl‐D‐aspartate receptor/channels were without effect. During the early stage of culture Ctx B, together with 25 mM K+, caused [Ca2+]i to rise to 0.2–0.7 μM in a higher proportion of cells than 25 mM K+ alone. A significant change in the nature of GM1 modulation of Ca2+ flux occurred after 7 days in culture, at which time Ctx B ceased to elevate and instead reduced [Ca2+]i below the level attained with 25 mM K+. GM1 thus appears to serve as intrinsic inhibitor of one or more L‐type Ca2+ channels during the first 7 days in vitro, and then as intrinsic activator of (possibly other) L‐type channels after that period. This is the first demonstration of a modulatory role for GM1 ganglioside affecting Ca2+ homeostasis in cultured neurons of the CNS. © 1996 Wiley‐Liss, Inc.
DOIS MODELOS CONTEMPORÂNEOS DE DIVULGAÇÃO FINANCEIRA NA INDÚSTRIA BANCÁRIA BRASILEIRA: QUAL É MAIS CONSERVADOR?

No âmbito do Sistema Financeiro Nacional [SFN], mesmo apos o Conselho Monetario Nacional [CMN] ter referendado alguns pronunciamentos do Comite de Pronunciamentos Contabeis [CPC], foi mantido o modelo contabil editado pelo Banco Central do Brasil [BCB], fundamentado no Plano Contabil das Instituicoes do Sistema Financeiro Nacional (Cosif). Em contrapartida, a Resolucao CMN no 3.786, de 2009, determinou que as instituicoes financeiras constituidas sob a forma de companhia aberta ou obrigadas a constituir comite de auditoria divulgassem, a partir de 2010, suas demonstracoes segundo os padroes definidos pelo IASB. Assim, essas instituicoes passaram a divulgar dois conjuntos de demonstracoes, elaboradas com base em padroes distintos. Este estudo teve como objetivo identificar qual dos modelos contabeis adotados por essas instituicoes – Cosif ou IFRS – apresenta de forma mais relevante a caracteristica do conservadorismo contabil condicional . Para isso, foi utilizado o modelo de componentes transitorios, desenvolvido por Basu (1997), tendo como amostra dados das demonstracoes financeiras anuais de 2010 a 2014, de 41 instituicoes. Os resultados dos testes empiricos demonstraram que nas demonstracoes elaboradas com base no padrao Cosif as variacoes relativas aos ganhos economicos nao eram persistentes, contrariando as premissas do conservadorismo condicional. Por outro lado, foram constatadas as caracteristicas do conservadorismo contabil condicional nas demonstracoes no padrao IFRS. A combinacao dessas evidencias conduziu a nao rejeicao da hipotese de pesquisa que previa que as demonstracoes financeiras anuais das instituicoes bancarias brasileiras apresentadas em padrao IFRS apresentam maior conservadorismo que as elaboradas no padrao Cosif.
A learning algorithm with a gradient normalization and a learning rate adaptation for the mini-batch type learning

The development of a high-performance optimization algorithm to solve the learning problem of the neural networks is strongly demanded with the advance of the deep learning. The learning algorithms with gradient normalization mechanisms have been investigated, and their effectiveness has been shown. In the learning algorithms, the adaptation of the learning rate is very important issue. The learning algorithms of the neural networks are classified into the batch learning and the mini-batch learning. In the learning with vast training data, the mini-batch type learning is often used due to the limitation of memory size and the computational cost. The mini-batch type learning algorithms with gradient normalization mechanisms have been investigated. However, the adaptation of the learning rate in the mini-batch type learning algorithm with the gradient normalization has not been investigated well. This study proposes to introduce a new learning rate adaptation mechanism based on sign variation of gradient to a mini-batch type learning algorithm with the gradient normalization. The effectiveness of the proposed algorithm is verified through applications to a learning problem of the multi-layered neural networks and a learning problem of the convolutional neural networks.
Costs of illness for melanoma and nonmelanoma skin cancer in Denmark

Incidences of melanoma and nonmelanoma skin cancer are high and increasing in many countries including Denmark. The diseases are highly preventable. We have estimated the healthcare costs of these cancers by comparing costs for cohorts of patients and matched controls in a national register-based study in Denmark. All incident patients with a diagnosis of melanoma, basal cell carcinoma, or squamous cell carcinoma in the period 2004–2008 were included. Four control individuals for each case were matched in terms of sex, age, and area of residence. Healthcare costs and productivity loss for patients and controls were estimated using Danish health and social registries 3 years before and 3 years after diagnosis. The healthcare costs of melanoma and nonmelanoma skin cancer were &OV0556;33.3 million in the 3-year period after diagnosis, with male patients inducing the highest costs for all three cancers and costs increasing with age. The diagnoses of basal cell carcinoma and melanoma had almost the same healthcare costs, but per patient average healthcare costs were higher for melanoma. The costs of melanoma and nonmelanoma skin cancers, which can be prevented by sensible sun habits, exceed the costs of the preventive measures of the Danish SunSmart campaign manifold. Costs of melanoma and nonmelanoma skin cancer are expected to increase in the future with populations aging in the western world. The analyses provide a strong argument for the societal rationale of skin cancer prevention in Denmark.
Making Your Wishes Known: Who Completes an Advance Directive and Shares It With Their Health Care Team or Loved Ones?

Using Andersen’s health behavioral model as a framework, this study examined factors associated with the completion of advance directives and the behavior of sharing them with one’s family and health care providers. Data were from the 2014 United States of Aging Survey (N = 1,153; aged 60 or older), and multinomial logistic regression was used for analysis. We found that 73% of respondents had advance directives. However, 28% have not shared their advance directives with anyone. The sense of having completed a great deal of preparation for the future and the number of illnesses were found to be relevant to the behavior of sharing advance directives. Existing educational training and interventions can be expanded to increase public awareness and encourage people to share their completed advance directives with others. Policies mandating physicians to engage in advance directive conversations with patients during annual checkups might improve completion and sharing of advance directives.
Mother-Child Relations and Adolescent Sexual Attitudes and Behavior

We hypothesize that children who are close to their parents are more likely to have attitudes and behavior that are consistent with their parents' values than children who are not close to their parents. Using data from a probability sample of 888 mother-child pairs of white women in the Detroit metropolitan area, we tested this hypothesis, using both mother's and child's attitudes toward premarital sexual intercourse and the child's report of whether he or she had engaged in premarital sexual intercourse. Unlike most previous work in this area, which has posited a direct association between the closeness of the mother-child relation and the child's attitudes and behavior, we found that the quality of the relation interacted with the mother's attitudes in its effects on the child's attitudes and behavior. Children with close relations with their mothers were more likely to hold attitudes and behave in a manner consistent with their mothers' own attitudes than children with more distant relations.
Sites and modes of action of proctolin and the FLP F2 on lobster cardiac muscle

SUMMARY At the threshold concentration (1-10 pmol l-1), the neuropeptide hormones proctolin (PR) and the FLRFamide-like peptide (FLP) F2 cause an increase in amplitude of electrically evoked contractions (each contraction is a brief tetanus) of lobster heart ostial muscle. At higher concentrations each peptide also induces an increase in tonus (contracture). The PR-induced contracture and augmentation of tetani are proportional to increases in [Ca2+]i. The rate of onset and recovery of peptide-induced effects on both tetani and contracture appeared to reduced by Ca2+ storage by the sarcoplasmic reticulum (SR). Enhanced tetani following a contracture may be due to enhanced voltage-gated Ca2+ current and sarcoplasmic reticular (SR) Ca2+ loading. The SR Ca2+ loading appears to be specific for PR and F2, since glutamic-acid-induced contractures are not followed by increased tetani. The prolonged elevation of [Ca2+]i during contracture causes a right-ward shift in the force-pCa curve indicating a decrease in myofibrillar sensitivity to Ca2+. Blocking voltage-gated Ca2+ channels with Cd2+, nifedipine or verapamil, while reducing tetani, does not prevent peptide-induced contracture and enhanced tetani. Opening SR Ca2+ channels and depleting SR Ca2+ with either caffeine or ryanodine blocked tetani but permitted accelerated peptide-induced contractures. We conclude that PR and F2 at low concentration enhance voltage-dependent Ca2+ induced Ca2+ release from the SR, while higher hormone levels directly gate Ca2+ entry across the sarcolemma.
