Authors: Polak Rafał , Laskowski Dariusz
Published: December 2016

The article refers to the impact of damage and dynamic variables on operation of routing protocols and consequently to the whole network (Technical Object - TO) determining its reliability and effectiveness. On this purpose, there was introduced the characteristic of the routing protocols and both an internal and an exterior gateway. Then, it was built the network architecture based on the TCP/IP stack. In the stack, there were created three autonomous systems and one of them was the backbone of the network. What is more, reliability tests, which have been performed, consisted of a resistance to physical damage to the network and dynamically changing parameters of the network as well as performance test.
Micromorphology of modern tills in southwestern Spitsbergen – insights into depositional and post-depositional processes
Authors: Skolasińska Katarzyna , Rachlewicz Grzegorz , Szczuciński Witold
Published: December 2016

Textural properties and microstructures are commonly used properties in the analysis of Pleistocene and older glacial deposits. However, contemporary glacial deposits are seldom studied, particularly in the context of post-depositional changes. This paper presents the results of a micromorphological study of recently deposited tills in the marginal zones of Hansbreen and Torellbreen, glaciers in southwestern Spitsbergen. The main objectives of this study were to compare modern tills deposited in subglacial and supraglacial conditions, as well as tills that were freshly released from ice with those laid down several decades ago. The investigated tills are primarily composed of large clasts of metamorphic rocks and represent coarse-grained, matrix-supported diamictons. The tills reveal several characteristic features for ductile (e.g.turbate structures) and brittle (e.g.lineations, microshears) deformations, which have been considered to be indicative of subglacial conditions. In supraglacial tills, the same structures are common as in the subglacial deposits, which points to the preservation of the primary features, though the sediment was transferred up to the glacier surface due to basal ice layer deformation and redeposited as slumps, or to formation of similar structures due to short-distance sediment re-deposition by mass flows. This study revealed that it might not be possible to distinguish subglacial and supraglacial tills on the basis of micromorphology if the latter are derived from a subglacial position. The only noted difference was the presence of iron oxide cementation zones and carbonate dissolution features in supraglacial tills. These features were found in tills that were deposited at least a few years ago and are interpreted to be induced by early post-depositional processes involving porewater/sediment interactions.
Software Usability: Concepts, Attributes and Associated Health Problems
Authors: Grīnberga Sabīne
Published: December 2016

Digital technologies have opened a large set of opportunities for new electronic services (e-commerce, e-health, e-studies etc.). There are many considerations that need to be made when programmers are building new application software or system software. The software needs to be attractive enough that people want to look at it. It also needs to contain all necessary information that developers want to share with their readers (customers, users) in order to help them achieve the objective for which they came to their website, use their software, or interact with their teaching packages. The oversupply of e-services products has created a need for usability research and development. “Usability means making products and systems easier to use, and matching them more closely to user needs and requirements”. Usability is a key concept of the human-computer interface and is concerned with making computer systems easy to learn and easy to use through a user-centered design process. The in-depth understanding of usability concepts and processes are critical for large-scale acceptance of new e-services and knowledge productivity. Poorly designed software can be extremely annoying to users. Smith and Mayes state that „usability is now recognised as a vital determining factor in the success of any new computer system or computer-based service”. Studies have shown that the main health problems of computer users are repetitive strain injuries, visual discomfort and stress-related disorders. Beside other risk factors, such as poor workstation design, uncomfortable work postures, long hours of computer use every day, stress, etc., also poor design and usability of the computer systems, as well as computer technical problems, add to the pressure felt by the user, which may in turn cause stress-related disorders.
Trust and Mistrust as Stress Reducing and Increasing Factors in Working Life
Authors: Piippo Jukka
Published: December 2016

This paper is a theoretical attempt to investigate possible connections between trust and eustress and also mistrust and distress. The paper includes both empirical material and theoretical material. Empirical material was analysed by using Grounded Theory. According to analysis of both empirical and theoretical material there are connections between the phenomena mentioned. Trust is connected to eustress by several categories, such as mutual process, openness, and leadership of self and versatile interchange of knowing. Mistrust and distress are also connected by several categories: incomprehensibility and embarrassment, indifference, change, and depersonalisation. There were also categories identified as ambivalent categories, since they could be connected to either eustress or distress.

Published: December 2016

Humans are exposed to chemicals and PM (particulate matter), including ultrafine particles (nanoparticles), mainly through inhalation. This creates a risk to their health. Another effect to exposure is expression of cytokines and their role in lung inflammation and morphpathogenesis. We conducted a pilot project based on testing of realistic exposure scenarios by describing morphological changes of the respiratory tract in Wistar rats (male) during a 30-day exposure in office where there was high intensity of printing activities. Tracheal tissue of experimental animals had increasing concentrations of inflammatory interleukin IL-1 and decreasing concentrations of IL-6 and TNF-α. The lungs of the experimental animals tended to show focal infiltration of inflammatory cells, vascular plethora, focal and/or diffuse localisation of lymphatic nodules, and also vascular sclerosis and focal emphysema. The results suggested potential dangerous and adverse effect of poor indoor air quality (particles, including nanoparticles, and chemical compounds) on respiratory tract tissue of rats.
Political Instability and Economic Growth: Evidence from Jordan
Authors: Sweidan Osama D.
Published: December 2016

This paper explores the link between political instability and economic growth in Jordan, which is a lower middle-income country located at the heart of the Middle East. Historically, this region has been living under protracted wars, clashes, violence and terrorist attacks. We can expect these events to influence economic growth via their effect on government spending. We employ two econometric techniques: ARDL model (OLS) and Kalman filter (ML) and use data over the period 1967–2009. We find political instability has a statistically significant negative effect on economic growth as well as on real government expenditures.
Biochar as a soil amendment
Authors: Medyńska-Juraszek Agnieszka
Published: December 2016

Biochar is a carbonaceous product of biomass pyrolysis under limited oxygen conditions. Due to the very good sorption properties material is used as a soil amendment. In recent years, much attention has been paid to biochar as a potential tool improving soil properties and fertility. The most important benefits of its use in agriculture is a significant increase of sorption capacity, reduced nutrient leaching, as well as slow release of macro- and microelements essential for plant growth, liming effect, increased water holding capacity, improved biological properties, resulting in an increase in crop yields. The aim of the study is to summarize the knowledge about the impact of biochar on soil environment, as well as identify areas and directions for future research on biochar application in soils impacted by human activities

Published: December 2016

For decades, electroencephalography (EEG) has been a useful tool for investigating the neural mechanisms underlying human psychological processes. However, the amount of time needed to gather EEG data means that most laboratory studies use relatively small sample sizes. Using the Muse, a portable and wireless four-channel EEG headband, we obtained EEG recordings from 6029 subjects 18–88 years in age while they completed a category exemplar task followed by a meditation exercise. Here, we report age-related changes in EEG power at a fine chronological scale for δ, θ, α, and β bands, as well as peak α frequency and α asymmetry measures for both frontal and temporoparietal sites. We found that EEG power changed as a function of age, and that the age-related changes depended on sex and frequency band. We found an overall age-related shift in band power from lower to higher frequencies, especially for females. We also found a gradual, year-by-year slowing of the peak α frequency with increasing age. Finally, our analysis of α asymmetry revealed greater relative right frontal activity. Our results replicate several previous age- and sex-related findings and show how some previously observed changes during childhood extend throughout the lifespan. Unlike previous age-related EEG studies that were limited by sample size and restricted age ranges, our work highlights the advantage of using large, representative samples to address questions about developmental brain changes. We discuss our findings in terms of their relevance to attentional processes and brain-based models of emotional well-being and aging.
Gourmet Samurai: Changing Food Gender Norms in Japanese TV
Authors: Stalker Nancy K.
Published: December 2016

Japan's obsession with food TV is rooted in its gourmet boom, beginning in the 1980s, when the strong economy encouraged mass consumption of expensive foods and foreign cuisines. Gourmet TV dramas are often based on a popular manga comic and typically reproduce hegemonic gendered food norms, with professional male chefs embodying food authority and expertise often acting as protagonists. In recent years, however, several popular new TV series have introduced a new gender archetype: masculine loners who care deeply about traditional or home-style foods, so-called B-kyū gurume (second-class gourmet) cuisine. This article analyzes four such recent programs and argues that the emerging “gourmet samurai” archetype resonates with audiences because of the recent elevation of B-kyū cuisine and, more fundamentally, the steep decline in the marriage rate, a topic of intense media speculation. The expanding ranks of Japanese singles suggest that many men now face increased responsibilities for choosing or preparing their own meals. The everyman heroes of these shows offer role models to the growing cadres of unmarried men, encouraging them to become manly connoisseurs or cooks of simple, traditional foods and conveying the message that food knowledge and pleasure is as acceptable and satisfying a pursuit as romance, career, or family.
The Effects of Human Rights on Economic Growth, 1965 to 2010
Authors: Cole Wade M.
Published: December 2016

A long-standing research question asks whether democracy promotes or inhibits development, but relatively few studies explore the developmental consequences of human rights. I analyze the effect of respect for bodily integrity rights and civil liberties on economic growth rates, measured as percentage changes in gross domestic product over pooled five-year intervals, for 138 countries between 1965 and 2010. Bodily integrity rights entail fundamental protections against torture, political imprisonment, extrajudicial killing, and disappearances. Civil liberties include the freedoms of speech, assembly, religion, and movement. The analyses make use of estimators designed to isolate causal directionality. I find that improvements in countries’ rated bodily integrity practices boost economic growth rates, even after accounting for other important explanatory factors and the possibility of reverse causality. Additional analyses suggest that this effect operates largely through increased domestic investment. Static levels in bodily integrity scores, conversely, have no effect on growth; neither do static levels of or dynamic changes in civil liberties.
“Mestizagem’ y ‘Transculturación” como políticas y prácticas de convivencia: Gilberto Freyre (Casa-grande & senzala, 1933) y Fernando Ortiz (Contrapunteo cubano del tabaco y del azúcar, 1940)
Authors: Nitschack Horts
Published: December 2016

En este artículo se comparan dos textos clásicos sobre la sociedad de plantación: Casa-grande & senzala (1933), del brasileño Gilberto Freyre, y Contrapunteo cubano del tabaco y el azúcar (1940), del cubano Fernando Ortiz. Los dos autores describen y analizan la convivencia de los grupos y sujetos de distintas proveniencias étnicas, culturales y sociales con dos conceptos que significan valoraciones profundamente diferentes: ‘mestizaje’ (Gilberto Freyre) y ‘transculturación’ (Fernando Ortiz). En el ‘mestizaje’ se mantiene el ‘mito de las tres razas’. El fundamento de la convivencia es, en última instancia, el mestizaje biológico bajo las condiciones de la sociedad colonial cuyas leyes y orden el proceso de mestizaje no pone en cuestión. La convivencia del mestizaje está marcada por la ambivalencia entre represión y protección. La ‘transculturación’ de Fernando Ortiz define los sujetospor sus prácticas sociales y por su posición en las configuraciones de poder económico y social. En consecuencia, se trata de procesos complejos de negociación en los cuales tanto el sujeto de dominación como el dominado están involucrados. A pesar de sus diferencias, los dos conceptos contribuyen significativamente a una revaluación de las culturas latinoamericanas en comparación con las culturas nórdicas.

De la insularidad a la continentalización: el neopolicial cubano de Leonardo Padura
Authors: Sarabia Rosa
Published: December 2016

Este estudio se centra en el recorrido y desarrollo de Mario Conde, detective  protagonista de las ocho novelas policiales del escritor cubano Leonardo Padura. De la tetralogía que se inicia con Pasado Perfecto,en 1991, hasta la ambiciosa y última entrega de Herejes, en 2013, Conde actúa mayormente dentro del “período especial” cubano marcado por la debacle de la Unión Soviética, para arribar a la primera década del siglo XXI. Dicho “período especial” produjo un quiebre en el desarrollo del género policial en Cuba. Por lo tanto, el género policial revolucionario, con apoyo oficial que nace a comienzos de la década de los 70, se transforma en los 90 para insertarse en la vertiente neopolicial que el resto de Latinoamérica venía desarrollando desde una década antes.Lejos de los personajes modélicos revolucionarios del género en su origen, el neopolicial de Padura crea personajes que resuelven crímenes y delitos pero a la vez delinquen y evaden la ley. A partir de los casos que investiga, Conde se mueve dentro de esa paradójica conducta, al mismo tiempo que deconstruye y desmitifica las grandes políticas y discursos revolucionarios.
¿Haití es aquí? El mar sin fronteras
Authors: Reis Lívia
Published: December 2016

El objetivo de este texto es proponer una reflexión sobre las teorías sobre la cultura o de la literatura originaria en los diferentes países del Caribe y su presencia en los estudios literarios y culturales del continente. Dibujado con amplias pinceladas, tiene el objetivo de poner en claro el ensayo titulado La isla que se repite (1998) del cubano Antonio Benítez Rojo y, a partir de su lectura, nos aproximamos de la canción Haití, de Caetano Veloso y Gilberto Gil, grabada originalmente en el CD Tropicalia II, de 1993.Los planteos de Benítez Rojo traen elementos que se encuentran en la base de  nuestra cultura, marcada por la presencia de los negros y de su cultura por toda América. De cada área y de cada región brotó un tipo de música y ritmo que tiene como rasgo común constituirse en una voz contra la tiranía. El negro spiritual, entonado en las iglesias de América del norte, el jazz, el blues, el samba, el son, el tango, la rumba, la salsa, el merengue, la cumbia, prácticamente todas las expresiones musicales de América, están relacionadas con la música y el ritmo producido por los negros desde que, por primera vez, pusieron los pies en nuestro continente
Demographic and occupational determinants of the work ability of firemen

Published: December 2016

Objectives

Firefighters tackle various stressors that affect their health and job performance; therefore, assessment of their work ability is necessary. This study aimed to investigate the demographic and occupational determinants of the work ability of firemen.

Methods

In this cross-sectional study, 375 firemen working in Tehran Fire Department were randomly selected. Demographic, occupational, and work ability index (WAI) questionnaires were applied as research tools.

Results

The mean firemen’s WAI score was relatively high. There were significant relationships between WAI and age, body mass index, work experience, and weekly leisuretime physical exercise hours. Single employees, those who did not have extra jobs and did not smoke, had greater scores compared to their counterparts. Poisson regression revealed that age and weekly leisure-time physical exercise hours could affect WAI significantly.

Conclusions

Although Iranian firemen revealed good work ability, recognizing factors affecting this ability and preparing facilities to promote their function is necessary.
Directly Comparing Handoff Protocols for Pediatric Hospitalists
Authors: Lazzara Elizabeth H. , Riss Robert , Patzer Brady , Smith Dustin C. , Chan Y. Raymond , Keebler Joseph R. , Fouquet Sarah D. , Palmer Evan M.
Published: December 2016

BACKGROUND AND OBJECTIVES:

Handoff protocols are often developed by brainstorming and consensus, and few are directly compared. We hypothesized that a handoff protocol (Flex 11) developed using a rigorous methodology would be more favorable in terms of clinicians’ attitudes, behaviors, cognitions, or time-on-task when performing handoffs compared with a prevalent protocol (Situation Background Assessment Recommendation [SBAR]).

METHODS:

Using a between-groups, randomized control trial design (Flex 11 versus SBAR) during a pilot study in a simulated environment, 20 clinicians (13 attending physicians and 7 residents) received 3 patient handoffs from a standardized physician, managed the patients, and handed off the patients to the same standardized physician. Participants completed surveys assessing their attitudes and cognitions, and behaviors and handoff duration were assessed through observations.

RESULTS:

All data were analyzed using independent samples t tests. For attitudes, “ease of use” ratings were lower for SBAR participants than Flex 11 participants (P < .01), and “being helpful” ratings were lower for SBAR participants than Flex 11 participants (P = .02). For behaviors, results indicate no significant difference in the information acquired between the SBAR and Flex 11 protocols. However, SBAR participants gave significantly less information than Flex 11 participants (P < .01). For cognitions, SBAR and Flex 11 participants reported similar workload except for frustration. For handoff duration, there were no significant differences between the protocols (P = .36).

CONCLUSIONS:

The results suggest that Flex 11 is an efficient, beneficial tool in a simulated environment with pediatric clinicians. Future studies should evaluate this protocol in the inpatient setting.
Congenital Diaphragmatic Hernia: Maximizing Survival
Authors: Weems Mark F. , Jancelewicz Tim , Sandhu Hitesh S.
Published: December 2016

Congenital diaphragmatic hernia occurs when a portion of the fetal diaphragm is absent, allowing abdominal contents to enter the thorax, and is associated with impaired pulmonary development. Although overall mortality is near 30%, a mortality rate less than 15% may be possible by following a standardized multidisciplinary care plan. Fetal diagnosis and evaluation can improve coordination of care, but there is no clear role for fetal intervention. After birth, gentle ventilation with permissive hypercapnia supports the infant while minimizing lung injury. Appropriate cardiovascular support, treatment of pulmonary hypertension, and extracorporeal membrane oxygenation may benefit some patients. Timing of surgical repair depends on disease severity. All patients should have close follow-up after discharge.

Authors: Noritz Garey , Madden Melissa , Roldan Dina , Wheeler T. Arthur , Conkol Kimberly , Brilli Richard J. , Barnard John , Gleeson Sean
Published: December 2016

BACKGROUND AND OBJECTIVES:

Children with medical complexity experience frequent interactions with the medical system and often receive care that is costly, duplicative, and inefficient. The growth of value-based contracting creates incentives for systems to improve their care. This project was designed to improve the health, health care value, and utilization for a population-based cohort of children with neurologic impairment and feeding tubes.

METHODS:

A freestanding children’s hospital and affiliated accountable care organization jointly developed a quality improvement initiative. Children with a percutaneous feeding tube, a neurologic diagnosis, and Medicaid, were targeted for intervention within a catchment area of >300 000 children receiving Medicaid. Initiatives included standardizing feeding tube management, improving family education, and implementing a care coordination program.

RESULTS:

Between January 2011 and December 2014, there was an 18.0% decrease (P < .001) in admissions and a 31.9% decrease (P < .001) in the average length of stay for children in the cohort. Total inpatient charges were reduced by $11 764 856. There was an 8.2% increase (P < .001) in the percentage of children with weights between the fifth and 95th percentiles. The care coordination program enrolled 58.3% of the cohort.

CONCLUSIONS:

This population-based initiative to improve the care of children with medical complexity showed promising results, including a reduction in charges while improving weight status and implementing a care coordination program. A concerted institutional initiative, in the context of an accountable care organization, can be part of the solution for improving outcomes and health care value for children with medical complexity.

Seaweed is one of resourceful plants in Indonesia. Some researchers suggested that brown seaweed has a potential to be an anti-inflammatory agent because it contains polysaccharide sulfate, PUFA, and fuchosantin. Punaga Village that is located in South Sulawesi is an area where most people work as seaweed farmer and cultivation of seaweed. This is why researcher found it interest to use natural sources as an alternative of herbal medicine especially as an anti-inflammatory. The objective of this study was to evaluate the difference of anti-inflammatory effect of brown algae extract Padina sp. and Sargassum sp. that is derived from Punaga Beach, South Sulawesi toward mice. Twenty male mice were used as sample in this study weighing 14-35 g and divided into four groups. Thirty minutes after injection of test material, 0.5 ml pepton 1% is injected into mice leg. The assessment of mice leg use plethysmometer that is taken on the first hour until fourth hour after injection of pepton 1%. Data analysis use T-test to find out the difference of anti-inflamatory effect of brown algae extract Padina sp. and Sargassum sp. The result of this study showed that brown algae extract Padina sp has p<0.05 and brown algae extract Sargassum sp. has p< 0.05 which means that there are anti-inflammatory effect found in both test materials. It is found that brown algae extract Padina sp.has longer anti inflammatory effect half time than in brown algae extract Sargassum sp.
Remote Measurement of Linear Polarization Resistance In Concrete Structures

The monitoring of corrosion in reinforced concrete structures is considered an important preventive factor against the corrosive damage. The present paper shows the design and construction of a device which performs remote measurements of the polarization resistance of reinforcing steel, this was made using the electrochemical technique of linear polarization resistance as a method to obtain the information of the corrosive process. The development was carried out by implementing a potentiostat based on a free development platform. The design allows to store all the data on a physical memory and to send the results through the mobile network to a web server, where the measured values can be analyzed using an internet connection.

The linear polarization resistance measurements were made in cylindrical concrete specimens with rebars of ½ ”, each one instrumented with embedded electrodes of Copper/Copper sulfate and graphite. The specimens were subjected to a saturated environment of chlorides (3.5%) where the corrosive process was monitored with the developed system. The results were compared with tests performed on a commercial potentiostat / galvanostat, where the values obtained have an mean of 4.83%.

This paper describes a new concept of flight crew assessment based on flight simulators training result. It is based on representation of pilot gaze movement with the aid of continuous-time Markov processes with discrete states. Considered are both the procedure of model parameters identification provided with goodness-of-fit tests in use and the classifier-building technique, which makes it possible to estimate degree of correspondence between the observed gaze motion distribution under study and reference distributions identified for different diagnosed groups. The final assessing criterion is formed on the basis of integrated diagnostic parameters, which are determined by the parameters of the identified models. The article provides a description of the experiment, illustrations, and results of studies aimed at assessing the reliability of the developed models and criteria, as well as conclusions about the applicability of the approach, its advantages and disadvantages.
A orixe literaria do nome da Coruña
Authors: Navaza Gonzalo
Published: December 2016

O nome actual da cidade naceu en 1208 para substituír o de Faro, que á súa vez substituíra o antigo de Brigantium. A institucionalización medieval do novo nome foi un acto administrativo do rei Afonso IX coincidente coa concesión aos veciños de Faro dunha carta foral que segue o modelo da concedida polo seu pai Fernando II aos de Benavente (Zamora), modelo que se aplicou noutras vilas reguengas dos reinos de Galicia e de León, ás veces con mudanza do nome do lugar. Cando se produce esta mudanza, as motivacións que levan os monarcas a escolleren os novos topónimos non son arbitrarias, senón que responden a criterios definidos, guiados por unha vontade augural ou de prestixio. De acordo con iso, deféndese a idea de que o nome que comeza rexistrándose en latín como Crunia en 1208 é un nome de orixe literaria, tomado dun topónimo que aparece na Historia Turpini, tamén coñecida como Historia Karoli Magni et Rotholandi ou Pseudo Turpín, isto é, o libro IV do Codex Calixtinus.

Published: December 2016

The Faculty of Agriculture (FoA) (University of Mauritius) is the only tertiary Education Institution in the country providing graduate training in Agriculture with an annual enrolment of about 100-125 students. Although the relative contribution of the Agricultural sector to the economy has declined over the past decade — share to GDP: 3.0% in 2014 as compared to 6.4% in 2004[1] the introduction of new schemes in support of Bio- Farming, food processing and value-addition will attract new entrepreneurs to Agriculture. This transformation in the Agriculture sector will create new job opportunities, but has to leverage on skilled human capital. Graduates with good employability skills are of strategic importance to the FoA, in line with the government’s vision to develop a knowledge-based economy. This study aimed at mapping out the set of skills, understandings and personal attributes that will increase the job prospects of the fresh graduate from FoA in Agriculture. The main research question centred on the perceptions of employers, alumni and students of the FoA, concerning the most relevant competences for the Subject Area (key general and key subject specific competences), understandings and personal attributes, which enhance the employability of graduates in Agriculture. Using semi-structured interviews, the study explored and triangulated the perceptions from four key stakeholders’ perspectives, namely: a range of employers, Industry Placement Supervisors, alumni of the FoA and current students. Both quantitative and qualitative insights of the perceptions on the employability skills of FoA undergraduates were obtained from a wide range of employers from the private and public sector. An analysis of data from the interviews and responses was carried out using SPSS. The key attributes that were valued by the key stakeholders have been used to inform the ‘Employability Skills Subject Area Framework’, and the ‘Curriculum Mapping’, proposed for the degree of BSc (Hons) Agriscience and Technology of the FoA.
