Does the Unemployment Benefit Institution Affect the Productivity of Workers? Evidence from the Field
Authors: Blanco Mariana , Dalton Patricio S. , Vargas Juan F. 
Published: August 2016

This paper studies the effects of unemployment benefit schemes on individual productivity. We created employment and unemployment in the field and compared workers’ productivity under no unemployment benefits to productivity under two different unemployment schemes. In one scheme, the unemployed received an unconditional monetary transfer. In the other, the monetary transfer was obtained conditional on the unemployed spending some time on an ancillary activity. Our results challenge the standard economic theory prediction that unemployment benefits, especially unconditional compensations, hinder workers’ effort. We find that workers employed under the unconditional scheme are more productive than workers under the conditional one, and both schemes make workers more productive than having no unemployment benefit. We discuss two possible explanations for our results based on reciprocity and differential psychological costs of unemployment across unemployment benefit schemes.

Lactic acidosis: an update
Authors: Seheult Jansen , Fitzpatrick Gerard , Boran Gerard 
Published: August 2016

AbstractLactate is one of the most crucial intermediates in carbohydrate and nonessential amino acid metabolism. The complexity of cellular interactions and metabolism means that lactate can be considered a waste product for one cell but a useful substrate for another. The presence of elevated lactate levels in critically ill patients has important implications for morbidity and mortality. In this review, we provide a brief outline of the metabolism of lactate, the pathophysiology of lactic acidosis, the clinical significance of D-lactate, the role of lactate measurement in acutely ill patients, the methods used to measure lactate in blood or plasma and some of the methodological issues related to interferences in these assays, especially in the case of ethylene glycol poisoning.

Published: August 2016

AbstractBackground:The systematic evaluation of the clinical concordance of various 25-hydroxyvitamin D (25OHD) testing methods is presented. The need for this approach is raised by the discrepancies in the analytical performance of the available assays.Methods:The analytical and clinical performance of six automated 25OHD assays and an in-house liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was investigated. Leftover serum samples (n=162, SA: n=114) were analyzed and all 21 assay combinations were evaluated. The utility of Cohen’s κ values was assessed by transforming them into minimum percentage agreement (MPA). McNemar’s hypothesis test was employed for testing the symmetry of the disagreeing classification outcomes within each method pair.Results:Depending on the assay method, the ratio of results classified as positive (<20 ng/mL) was 13.5%–40.0%. The percentage agreement (PA) was 74.1%–92.6%. Compared to other methods, significantly more hypovitaminosis cases were delivered by DiaSorin Liaison® 25 OH vitamin D Total (DL) and significantly fewer by IDS-iSYS 25-Hydroxy Vitamin DS (II). The strongest clinical concordance was exerted by II vs. LC-MS/MS. The κ-derived MPA showed close similarity to the PA scores. McNemar’s tests confirmed the asymmetry of the disagreement in the classification in 14 method combinations.Conclusions:The presented approach allows the prediction of the clinical consequences of a 25OHD method transfer. Differences in the clinical classification of assay results are likely encountered when transferring to a new method, even between assays standardized according to the Vitamin D Standardization Program (VDSP) Reference Method Procedure (RMP).

Abstract
Plastic solid waste (PSW) presents challenges and opportunities to society regardless of their sustainability awareness and technological advances. A special emphasis is paid on waste generated from polyolefin sources, which makes up a great percentage of our daily commodities’ plastic products. In Mexico 7.6 millions of tons of plastic in 2012 were wasted, which low density polyethylene LDPE, and high density polyethylene HDPE were the most abundant. Increasing cost, and decreasing space of landfills are forcing considerations of alternative options for PSW disposal. Years of research, study and testing have resulted in a number of treatment, recycling and recovery methods for plastics that can be economically, and environmentally viable. The following work studies the possibilities of polyethylene recycling. Nowadays, non-catalytic thermal cracking (Pyrolysis) is receiving renewed attention, due to the fact of added value on a crude oil barrel and its very valuable yielded products, but a fact remains that advanced thermo-chemical recycling of polyolefin still lacks the proper design, and kinetic background to target certain desired products and/or chemicals. On the other hand some research have shown a good performance that can be used in a real plant. ASPEN Plus is used to simulate a non-catalytic thermal cracking process. The process behavior of simulation is similar to the experimental data from other authors. Using gibbs free energy to identify the chemical equilibrium in system, its global minimization allows identifying the amount of substances present in the process. The simulation results demonstrate that it could be produced 49 % and 34 % wt of ethylene and propylene respectively from gas yield at 850 °C. Then scale the plant to produce ethylene and propylene from the pyrolysis and ethanol from a direct hydration of ethylene. Aspen Process Economics Analyzer is used in order to find the feasibility of the pyrolysis and ethanol production. The total sales/total production cost ratio obtained for the integrated process approaches was 2.55.

Determinants of dietary behaviour during pregnancy
Authors: Doyle Ina-Merle , Spallek Jacob 
Published: August 2016

Abstract:
Diet is crucial for maternal and child health, and pregnancy may be a good time for initiating behaviour change. Research from developed countries indicates inadequate diets despite food abundance. Dietary behaviour in pregnancy appears to be determined by socio-demographic, lifestyle, pregnancy-related and environmental factors. Practitioners should pay particular attention to younger and less educated women as well as those showing low levels of health consciousness.

Published: August 2016

Abstract
Alzheimer’s disease (AD) is a common health problem in elderly people. There has been considerable research toward the diagnosis and early detection of this disease in the past decade. The sensitivity of biomarkers and the accuracy of the detection techniques have been defined to be the key to an accurate diagnosis. This paper presents a state-of-the-art review of the research performed on the diagnosis of AD based on imaging and machine learning techniques. Different segmentation and machine learning techniques used for the diagnosis of AD are reviewed including thresholding, supervised and unsupervised learning, probabilistic techniques, Atlas-based approaches, and fusion of different image modalities. More recent and powerful classification techniques such as the enhanced probabilistic neural network of Ahmadlou and Adeli should be investigated with the goal of improving the diagnosis accuracy. A combination of different image modalities can help improve the diagnosis accuracy rate. Research is needed on the combination of modalities to discover multi-modal biomarkers.
Exemplarbasierte Annäherungen an das Silbengelenk

Published: August 2016

Abstract
Using elicited experimental data from 35 kindergartners, this article investigates the ability of children aged 3–6 to deal with German ambisyllabic consonants. In this age group – yet without structured tuition in reading and writing, the development of the phonologic system still in progress – both intra- and inter-subject variation appears to be greater than previous studies conducted on school children revealed. It is argued that this variability supports the view of an exemplar-based theory on language acquisition; stable analytic knowledge on this specific syllable structure emerges as a function of age and frequency. Simultaneously, the data suggest a second kind of underlying variation, stemming from the contact of two conflicting typological syllable systems.

Published: August 2016

BACKGROUND:
There has been a dramatic increase in the off-label use of ophthalmic timolol maleate, a β-blocker used for infantile hemangioma (IH) treatment as a topical counterpart to oral propranolol. Its safety and efficacy in a pediatric population with IH have not been evaluated in a large cohort. Our goal was to retrospectively assess timolol’s effectiveness, discern characteristics associated with response, and document reported adverse events.

METHODS:
A multicenter retrospective cohort study of 731 patients treated with topical timolol was completed at 9 centers. Inclusion required an IH suitable for timolol in the treating physician’s judgment and access to clinical details including photographs. Logistic regression analysis and descriptive statistics were performed. Primary outcome measures were efficacy assessed by using visual analog scales for color and for size, extent, and volume from review of digital photographs taken as standard of care.

RESULTS:
Most IHs were localized (80.1%) and superficial (55.3%). Risk of disfigurement was the most common indication for therapy (74.3%). Duration of therapy (P &lt; .0001), initial thinness (P = .008), and subtype (P = .031) were significant predictors of response. Best response occurred in superficial IHs &lt;1 mm thick. Fifty-three (7.3%) required subsequent therapy with systemic β-blocker. Adverse events were mild, occurring in 25 (3.4%) patients. No cardiovascular side effects were documented.

CONCLUSIONS:
Timolol seems to be a well-tolerated, safe treatment option with moderate to good effectiveness, demonstrating best response in thin, superficial IHs regardless of pretreatment size. Timolol can be recommended as an alternative to systemic β-blockers and watchful waiting for many patients.
Nocturnal Video Assessment of Infant Sleep Environments

Published: August 2016

BACKGROUND AND OBJECTIVE:
Reports describing factors associated with sleep-related infant death rely on caregiver report or postmortem findings. We sought to determine the frequency of environmental risk factors by using nocturnal sleep videos of infants.

METHODS:
Healthy, term newborns were recruited for a parent study examining the role of parenting in the development of nighttime infant sleep patterns. For 1 night at ages 1, 3, and 6 months, video recordings were conducted within family homes. Videos were coded for sudden infant death syndrome risk factors in post hoc secondary analyses after the parent study was completed.

RESULTS:
Among 160 one-month-olds, initially 21% were placed to sleep on nonrecommended sleep surfaces and 14% were placed nonsupine; 91% had loose/nonapproved items on their sleep surface, including bedding, bumper pads, pillows, stuffed animals, and sleep positioners. Among 151 three-month-olds, 10% were initially placed on a nonrecommended sleep surface, 18% were placed nonsupine, and 87% had potentially hazardous items on their sleep surface. By 6 months, 12% of the 147 infants initially slept on a nonrecommended surface, 33% were placed to bed nonsupine, and 93% had loose/nonrecommended items on their surface. At 1, 3, and 6 months, 28%, 18%, and 12% changed sleep locations overnight, respectively, with an increased likelihood of bed-sharing and nonsupine position at the second location at each time point.

CONCLUSIONS:
Most parents, even when aware of being recorded, placed their infants in sleep environments with established risk factors. If infants were moved overnight, the second sleep environment generally had more hazards.

Objetivou-se avaliar o estresse, auto-percepção de estresse e de fatores estressantes em cuidadores de crianças com Transtorno do Déficit de Atenção e Hiperatividade (TDAH). Participaram 40 cuidadores, divididos em: Grupo clínico (G1) – 20 cuidadores de crianças diagnosticadas com TDAH; Grupo de comparação (G2) – 20 cuidadores de crianças sem TDAH. Utilizaram-se os instrumentos: Questionário de Capacidades e Dificuldades, Inventário de Sintomas de Stress para Adultos de Lipp, Questionário de Auto-Percepção de estresse. Os resultados apontaram percentual de cuidadores com indicadores de estresse significativamente maior no G1 do que encontrado no G2 (p = 0,001). No G1 houve maior percepção de estresse no convívio com a criança (p < 0,001), no cuidado com a criança (p < 0,001) e maior percepção de estresse (p = 0,003) quando comparados ao G2. Destaca-se a necessidade de cuidado ao cuidador, pois a vivência de estresse afeta a qualidade de vida, bem como a relação e o vínculo entre este e a criança.

Published: August 2016

Bobbin tool friction stir welding (BTFSW) is a new solid-state welding technology that has been developed successfully in many joining applications, such as thick plate and hollow component welding. The existence of the gap can possibly cause an unstable welding, and the variety of the torque is closely related to the existence of the gap. Compared with the conventional friction stir welding (FSW), BTFSW has the different tool and welding process, especially some new feature of the periodic vibration signal arises when welding two sheets in the presence of gaps. Compared with vibration-accelerated signal, torque signal is capable of reflecting the vibration of the welding process. The aim of this study was to develop an effective algorithm to detect gaps in BTFSW operations. Experimental studies were conducted to determine the features of welding process parameters and the gap. Time-frequency (TF) analysis provides a display of subtle torque features, shows the corresponding duration of low frequency signal clearly. Followed by a low-pass filter, gauss wavelet transform (WT) algorithm would improve the detection and identification of the gap presence. Several experimental studies with a variety of process parameters and proposed algorithm was shown to be able to reliably detect the presence of gaps in BTFSW operations for traverse speeds below 200 mm/min and gap sizes above 0.3 mm. This gauss WT algorithm could become a useful noninvasive tool for welding quality assessment in practice.

O objetivo do presente artigo é analisar o impacto da rede social Facebook no comportamento de compra do consumidor curitibano. Especificamente, a pesquisa procurou entender como o público-alvo busca o produto e até que ponto informações nas redes sociais tem influência sobre seus comportamentos, ou sejam se compram mais ou se têm lembrança da marca em momentos decisivos. Os dados foram coletados por meio de uma amostra de 100 consumidores em Curitiba/PR e analisados a partir da interpretação da descrição estatística dos dados. Concluiu-se, a partir dos dados, que as marcas que mantém seus perfis ativos no Facebook não influenciam o comportamento do consumidor e não estimulam diretamente a compra, porque os consumidores buscam lazer, informação e conteúdos relevantes no Facebook, mas têm oportunidades de estabelecer e estreitar relacionamento com seus consumidores.
