Does like seek like?: The formation of working groups in a programming project
Authors: Sanou Gozalo Eduard , Hernandez-Fernandez Antonio , Arias Marta , Ferrer-i-Cancho Ramon
Published: June 2017

In a course of the degree of computer science, the programming project has changed from individual to teamed work, tentatively in couples (pair programming). Students have full freedom to team up with minimum intervention from teachers. The analysis of the couples made indicates that students do not tend to associate with students with a similar academic performance, maybe because general cognitive parameters do not govern the choice of academic partners. Pair programming seems to give great results, so the efforts of future research in this field should focus precisely on how these pairs are formed, underpinning the mechanisms of human social interactions.

Homicides of Mental Health Workers by Patients: Review of Cases and Safety Recommendations
Authors: Knable Michael B.
Published: June 2017

A systematic search for accounts describing homicides of mental health workers between 1981 and 2014 was conducted. Demographic characteristics of the mental health workers and clinical characteristics of the perpetrators were collected. These data revealed that homicides occurred at a frequency of approximately 1 per year. Young women caseworkers who were unaccompanied during visits to residential treatment facilities were the most common victims. Men with a diagnosis of schizophrenia were the most common perpetrators. The most likely method of homicide was by gunshot (42.4%), but 57.6% of homicides were committed by less lethal, and possibly preventable, means. Perpetrators often had a prior history of violence, criminal charges, involuntary psychiatric hospitalization, or nonadherence to medications. After their legal trial, perpetrators were more likely to be imprisoned than hospitalized. Strategies to accurately identify risk and to train acute care staff in possible prevention measures are much needed. Some policy and training recommendations are offered in conclusion.

Considerations for the Propagation and Conservation of Endangered Lake Suckers of the Western United States
Authors: Day Julie L. , Jacobs Jennifer L. , Rasmussen Josh
Published: June 2017

Decades of persistent natural and anthropogenic threats coupled with competing water needs have compromised numerous species of freshwater fishes, many of which are now artificially propagated in hatcheries. Low survival upon release is common, particularly in systems with substantial nonnative predator populations. Extensive sampling for Shortnose (Chasmistes brevirostris) and Lost River Suckers (Deltistes luxatus) in the Klamath River Basin on the California–Oregon border have failed to detect any new adult recruitment for at least two decades, prompting an investigation into artificial propagation as an extinction prevention measure. A comprehensive assessment of strategies and successes associated with propagation for conservation restocking has not been performed for any Catostomid. Here, we review available literature for all western lake sucker species to inform propagation and recovery efforts for Klamath suckers and summarize the relevance of these considerations to other endangered fishes.
Point process methods in epidemiology: application to the analysis of human immunodeficiency virus/acquired immunodeficiency syndrome mortality in urban areas
Authors: Quesada Jose Antonio , Melchor Inmaculada , Nolasco Andreu
Published: June 2017

The analysis of spatio-temporal patterns of disease or death in urban areas has been developed mainly from the ecological studies approach. These designs may have some limitations like the ecological fallacy and instability with few cases. The objective of this study was to apply the point process methodology, as a complement to that of aggregated data, to study HIV/AIDS mortality in men in the city of Alicante (Spain). A case-control study in residents in the city during the period 2004-2011 was designed. Cases were men who died from HIV/AIDS and controls represented the general population, matched by age to cases. The risk surfaces of death over the city were estimated using the log-risk function of intensities, and we contrasted their temporal variations over the two periods. High risk significant areas of death by HIV/AIDS, which coincide with the most deprived areas in the city, were detected. Significant spatial change of the areas at risk between the periods studied was not detected. The point process methodology is a useful tool to analyse the patterns of death by HIV/AIDS in urban areas.
Museums and Memories: Remembering the Past in Local and Community Museums
Authors: Wilton Janis
Published: June 2017

This article explores the memories created and promoted through museums. It pays attention to the roles of curators, communities and critics as they argue about who controls the memories put on display. It investigates the ways in which the memories and memorialising of founding collectors and collections influence the form and messages of museums. Finally, it ponders the nature and impact of the memorable museum moments which visitors take with them.
Red Dog, Horses and Bogong Moths: The Memorialisation of Animals in Australia
Authors: Searby Rose
Published: June 2017

In this article I examine ways in which animals are memorialised in Australia. By examining the narratives surrounding horses in the Snowy Mountains of New South Wales, ceremonies for Bogong moths, and touching upon the stories of Red Dog, I show how the intangible can be considered a memorial and a memorial landscape conceived as one that is co-constructed by humans and animals. Understanding memorialisation as intangible facilitates a repositioning of animals in relation to humans and the creation of a new framework of reference for memorialising animals.
Remembering Bonegilla: The Construction of a Public Memory Place at Block 19
Authors: Pennay Bruce
Published: June 2017

This article traces the emergence of Block 19 Bonegilla as a heritage site. I examine shifts in official heritage value through three different heritage listings. I indicate how agencies, like the Bonegilla Steering Committee of which I am a member, are going about the task of interpreting the site using official, staff, resident and host society recall to explain the significance of the place. Disparate sources yield different insights into refugee and migrant arrival experiences, and we are trying to unravel the mix of stories that arise in a place that draws on living memory. We want to address host society experiences of post-war immigration. We want to attract and engage visitors. Such interpretation and presentation tasks involve us in constructing a public memory place.
Remembrance of Dutch War Dead in Southeast Asia, 1942-1945
Authors: Steijlen Fridus
Published: June 2017

Recognition of the war experience in Southeast Asia in the Netherlands was not easy. The Indisch community, those who had to leave the Netherlands East Indies after decolonization, did not feel that their war experience was accepted. Following the story of one man, a former POW, this article shows how unorthodox ways of protesting were used to command respect and acknowledgement. The arena for these actions was not only the Indisch monument in the Netherlands, but also the War cemetery in Thailand. The former Dutch POW ended up in a dispute with the Australian caretaker of that cemetery over the specific location of a camp. Both men, however, were motivated by the same urge to find the exact locations of camps along the Burma railway. The story of this POW shows how important official recognition is on a personal level.
Renewing the New Order?: Public History in Indonesia
Authors: Ashton Paul , Brahmantyo Kresno , Keaney Jaya
Published: June 2017

After the fall of the Suharto regime in 1988, public debates over the nature of history proliferated. While focusing on a number of key national events, most notably the 1965 coup and the killing of over half-a-million people, these debates have raised critical issues over the role or potential role of public history in contemporary Indonesian society. Questions of historical authority are paramount as Indonesian historians, public intellectuals and politicians struggle with a deeply entrenched historical paradigm and narratives of the old ‘New Order’ which continues to inform history in schools, cultural institutions, the media, literature, personal narratives, public rituals and the academy. This paradigm was based on an unquestioning acceptance of official accounts of the past. The demise of the New Order has left a historiographical vacuum which individuals and groups from a broad range of perspectives are trying to fill. Some, like Professor Azumardi Aza, are seeking to straddle the divide between professional and public history. Memory has emerged as a key issue in public debates, attempts have been made at reconciliation between the left and the right, though these faltered, and turf wars have broken out between historians and novelists such as Pramoedya Anata Toer. Women continue to remain relegated to a 'macabre footnote' in Indonesian public history. History in Indonesia is at a crossroads. One road could lead to a more democratic form of public or people’s history; the other to a modified version of the New Order history.
‘What better excuse for a real adventure’: History, Memory and Tourism on the Kokoda Track
Authors: Hawkins Jo
Published: June 2017

Rapidly growing numbers of Australian tourists visiting overseas battle sites associated with Australian military history have been met with enthusiastic academic interest by historians, yet the vast majority of studies focus on Gallipoli, rather than the Kokoda Track. Prior to 2001, few tourists had undertaken a journey along the narrow jungle pathway, which winds 96km through the Owen Stanley Ranges in Papua New Guinea. Just over a decade later, the track supports a competitive tourism industry, dominated by Australian companies, and attracts thousands of trekkers each year. This paper applies an interdisciplinary methodology to better understand the duality of locations of battlefield tourism as sites of commemoration and, unavoidably, sites of commerce. A survey of 107 trekkers suggests that, in addition to an expression of national identity, the mythology associated with the Kokoda Track has been appropriated by Australian tourists to represent individualistic goals of personal development and transformation: meanings that originate from the site’s history but extend beyond it.
Locating Archives within the Landscape: Records, Memory and Place
Authors: Bastian Jeannette
Published: June 2017

Linking archives, memory and landscape, this article considers a series of questions, and attempts to address some of them: How do archivists and scholars who concern themselves with archives think about place and its relationship to records? Why and how is place archival? How are those archival relationships expressed and what do they signify for the people inhabiting that space? What are the memory implications of the relationship between place, archives and community and how are traditional archives both the products of place as well as influencers themselves upon the landscape?
A novel method for deriving the aerosol hygroscopicity parameter based only on measurements from a humidified nephelometer system
Authors: Kuang Ye , Zhao Chunsheng , Tao Jiangchuan , Bian Yuxuan , Ma Nan , Zhao Gang
Published: June 2017

Abstract. Aerosol hygroscopicity is crucial for understanding roles of aerosol particles in atmospheric chemistry and aerosol climate effects. Light-scattering enhancement factor f(RH, λ) is one of the parameters describing aerosol hygroscopicity, which is defined as f(RH, λ) = σsp(RH, λ)∕σsp(dry, λ), where σsp(RH, λ) or σsp(dry, λ) represents σsp at wavelength λ under certain relative humidity (RH) or dry conditions. Traditionally, an overall hygroscopicity parameter κ can be retrieved from measured f(RH, λ), hereinafter referred to as κf(RH), by combining concurrently measured particle number size distribution (PNSD) and mass concentration of black carbon. In this paper, a new method is proposed to directly derive κf(RH) based only on measurements from a three-wavelength humidified nephelometer system. The advantage of this newly proposed approach is that κf(RH) can be estimated without any additional information about PNSD and black carbon. This method is verified with measurements from two different field campaigns. Values of κf(RH) estimated from this new method agree very well with those retrieved by using the traditional method: all points lie near the 1 : 1 line and the square of correlation coefficient between them is 0.99. The verification results demonstrate that this newly proposed method of deriving κf(RH) is applicable at different sites and in seasons of the North China Plain and might also be applicable in other regions around the world.
An improved water correction function for Picarro greenhouse gas analyzers
Authors: Reum Friedemann , Gerbig Christoph , Lavric Jost V. , Rella Chris W. , Göckede Mathias
Published: June 2017

Abstract. Measurements of dry air mole fractions of atmospheric greenhouse gases are widely used in inverse models of atmospheric tracer transport to quantify the sources and sinks of the gases. The measurements have to be calibrated to a common scale to avoid bias in the inferred fluxes. The World Meteorological Organization (WMO) has set requirements for the inter-laboratory compatibility of atmospheric greenhouse gas measurements to ±0.1 ppm for CO2 (Southern hemisphere ±0.05 ppm) and to ±2 ppb for CH4. An established series of devices for measurements of greenhouse gas (GHG) mole fractions are the trace gas analyzers manufactured by Picarro, Inc. These have been shown to deliver dry air mole fractions with accuracies within the WMO goals when trace gas signals are measured in wet air and the effects of water vapor are corrected for. Here, we report for the first time on sensitivity of the pressure inside the measurement cavity of Picarro GHG analyzers to water vapor. This sensitivity induces biases in the inferred dry air mole fractions of CO2 and CH4 if they are obtained using the traditional water correction function. To correct for the pressure effect, we add a pressure-related term to the traditional water correction function, and consider differences between the traditional and enhanced water correction function to be biases of the traditional model. The effect primarily affects low water vapor mole fractions from about 0.05 to about 0.5 %, a domain that has gone undersampled in previous studies of the water correction for Picarro GHG analyzers. We observed biases up to about 40 % of the WMO tolerances (80 % for CO2 in the southern hemisphere). The magnitude of the effect varied across instruments and appeared to be negligible for some, and our experimental results were more robust for CH4 than for CO2. Thus, correction coefficients should be determined for each analyzer individually. Applying our enhanced water correction function improves the accuracy of measurements of dry air mole fractions of CO2 and CH4 in humid air with Picarro GHG analyzers on a scale important for keeping the measurement accuracy within the WMO requirements.
Dead Sea evaporation by eddy covariance measurements versus aerodynamic, energy budget, Priestley–Taylor, and Penman estimates
Authors: Metzger Jutta , Nied Manuela , Corsmeier Ulrich , Kleffmann Jörg , Kottmeier Christoph
Published: June 2017

Abstract. The Dead Sea water budget is no longer in equilibrium. The lake level decline exceeds 1 m a−1 and causes severe environmental problems, such as a shifting of the fresh/saline groundwater interface and climatic changes. As the Dead Sea is a terminal lake, located in an arid environment, evaporation is the key component of the Dead Sea water budget and accounts for the main loss of water. However, the actual amount of evaporation as well as the governing factors are unknown. Therefore, for the first time, long-term eddy covariance measurements were performed for a period of one year, starting in March 2014. The total annual amount measured at this location was 994 ± 81 mm a−1. The median daily evaporation rate reaches 4.3 mm d−1 in July and only 1.1 mm d−1 in December. The wind velocity and vapour pressure deficit were identified as the main governing factors of evaporation throughout the year. Consequently, the local wind systems define the diurnal evaporation cycle. In the evening, strong downslope winds govern the wind field and cause evaporation amounts which are up to 100 % higher than during daytime, and also during the night evaporation rates are accelerated compared to daytime evaporation, due to strong northerly along-valley flows. Furthermore, a robust and reliable regression model is presented to calculate sub-daily and multiday evaporation values with a linear function of wind velocity and vapour pressure deficit. An overall correlation coefficient of 0.8 is achieved and the cross validation results in a prediction error of 4.8 %. Finally, indirect evaporation approaches were tested for their applicability for the Dead Sea and compared to the measurements. The aerodynamic approach is applicable for sub-daily and multi-day calculations and attains correlation coefficients between 0.85 and 0.99. For the application of the Bowen-Ratio-Energy-Balance (BREB) method and the Priestley–Taylor method, measurements of the heat storage term are inevitable to calculate evaporation on time scales up to one month. Without the heat storage term, the equations yield strong seasonal biases and over- or underestimate daily evaporation rates by up 100 %. The usage of an empirically gained linear function or a hysteresis model depending on the net radiation to estimate the heat storage term was not accurate enough to provide reliable evaporation amounts. The Penman equation was adapted to calculate realistic evaporation amounts, by using an empirically gained linear function for the heat storage term. The correlation coefficients are above 0.9, the daily mean difference is only 0.5 mm d−1 and the estimated annual amount is within the range of the measurement uncertainties. In summary, this study provides the first directly measured amounts of Dead Sea evaporation and applicable methods to calculate evaporation.

Marketing Communication Strategies for Generation Y – Millennials
Authors: Naumovska Ljupka
Published: June 2017

The marketing academics and researchers have studied members of Generation Y, recognized as Millennials who are born between the late ‘70s and middle ‘90s. This particular interest for research of Millennials continues due to questions concerning buying habits, consumer psychology and other related specifics, shaping this group as noticeably different in various means from its predecessors.Generation Y is a distinctive and dominant consumer group whose behavior, habits and consumers’ psychology is often discussed but not fully comprehended yet. Severely influenced by the technology revolution, the digital media development and the Internet, this market segment has developed differently from previous generations making it an interesting group for targeting for advertisers and brands. At this point, Generation Y is the largest market segment; hence the increased interest in categorizing and understanding characteristics of Generation Y from marketers. A contribution to the marketing theory and industry can be made with this paper, providing useful data for the consumer behavior of Generation Y, deeper understanding for their buying habits and consumer’s profile and most importantly media preferences as a basis for deeper and qualitative consideration of this marketing segment.
Investigating an Equitable Approach to Individualising Grades for Wiki-focused Project-based Learning in an English for Academic Purposes Context
Authors: Kebble Paul , Williams Simon
Published: June 2017

Project-based learning has enduring concerns with an individual contributor’s grade allocation. An individual’s final grade can be attained through whole group product assessment, individualised contribution assessment, or a combination of the two. Assessment can be achieved through external (teacher) product evaluation, internal (participant) process evaluation, or a combination of the two. If combination assessment is used, weighting of each element becomes an addressable issue. If a project utilises digital technologies, with a wiki being the predominant output format, the inherent software adds a further dimension to the assessment process. When the project is conducted by English language learners preparing for English-medium undergraduate studies, assessment becomes both linguistic and topic-focused. A limited two-cycle action research study was conducted at an English medium international university to investigate assessment methods utilising external and internal evaluations, on which the design of an assessment framework could be based. Results from this study include a design approach to the allocation of individual grades, with an informed discussion of group assessment, including free-rider issues, co-created assessment, and score weightage.

Authors: Dasopang Aisyah Fitriani
Published: June 2017

This study is aimed to analyze the interrelation of semantic and semiotic meaning in traditional Mandailingnese wedding song. The researcher studied lexical meaning and metaphor meaning in the song and the bridal gift which indicates has semiotic meaning. This study was a descriptive qualitative research. In conducting the research, the researcher has chosen Rere Mana Rere song. The result of the data analysis showed that the lexical and the metaphor meanings were used in Rere Mana Rere as traditional Mandailingnese wedding song. There were terminologies in lyrics that have interrelation of semantic and semiotic meaning. The speech function which dominantly used was noun. Understanding the relation of semantic and semiotic meaning of the song is important to listeners so they will get real meaning of the song. This study provided the analysis of both kinds of semantic and semiotic meaning and their relation were found in the Rere Mana Rere song.
The Bantu Preprefix, Morphology, Phonology or Syntax?
Authors: Goodness Devet
Published: June 2017

Bantu languages are characterized with the presence of an initial element that appears after a noun class prefix. This initial element (also known as initial vowel, pre-prefix or augment) has attracted the attention of most Bantuists. One issue of concern with regard to this initial element (hereafter called the preprefix) is related to its form, its distribution and its function. A question often asked is concerned with what triggers its occurrence in Bantu languages. This paper seeks to examine the preprefix in Bantu so as to come to grips with what triggers its occurrence in different Bantu languages. The findings indicate that the preprefix in Bantu may be associated with phonology, morphology and syntactic contexts. It has been revealed that in some cases, the preprefix in Bantu is triggered by its phonological context, morphology in some contexts and syntax in other contexts. It has been revealed that of all these three criteria (i.e morphology, phonology and syntax) syntax plays a greater role in the manifestation of the preprefix. However, in this paper it is concluded that the occurrence of the preprefix cannot be associated with a single aspect.
Microecology of Monogenean Gill Parasites of Tilapia Rendalli Boulenger, 1897 From Bamendjing Lake, Cameroon
Authors: Jeannette TOMBI , Miriane TCHIEGNO Joëlle , Francis AKOUMBA John
Published: June 2017

The present work aimed to study preferences for microhabitat by the monogenean gill parasites of Tilapia rendalli Boulenger, 1897. Fifty-four specimens were sampled using gill net in February 2014 at Bamendjing Lake. Each gill arch was removed and examined to both quantify the number of parasites and their distribution on the gills. This examination enabled us to find 6583 specimens of monogeneans belonging to 5 different species, Cichlidogyrus arthracanthus, C. dossoui, C. quaestio, C. tiberianus and C. tilapiae with 3708, 1708, 858, 210 and 99 individuals respectively. All species were aggregated within the host population. The spatial distribution of each parasite species was studied on different partitions of the gill arches. This study supports the hypothesis that gill site preference is a result of water flow over gills during respiration and mate finding habitat. There was no evidence of competition among the various species.
A Historical Review of the Benefits and Hypothetical Risks of Disinfecting Drinking Water by Chlorination
Authors: Cheung Philip C.W.
Published: June 2017

This review examines the benefits and alleged risks associated with the disinfection of drinking water by chlorination, through critical appraisal of the historical saga of chloroform as the main disinfection by-product (DBP). The author maintains that the provision of clean drinking water is a survival issue for humankind and supports unreservedly the recommendation by the World Health Organization (WHO) of the United Nations to disinfect by chlorination, for the reasons stated herein. The author aims to lead water professionals to a deeper understanding of the public health issues concerning chloroform and how the corpus of knowledge was attained by colossal multi-disciplinary effort on a global scale.Origins of the alleged risks of chlorination are traced and the assumptions behind these allegations are questioned. The author welcomes and encourages innovations for improved methods of water treatment insofar that the standards of potability set out by the WHO are met in the very least, but argues that the commencement point of research into new techniques should be an acknowledgment of the development of disinfection up to contemporary times, on the part of water engineers and policy makers. There must be a clear recognition of the horrific consequences of failure to eliminate pathogens and toxic substances. To this effect, landmark tragedies are described to emphasize the point.Significantly, this work addresses topics which are sine quo non to the debate over chlorination but which are often lacking in public discourse, namely: differences in the way cytochrome P450 enzymes oxidize carbon tetrachloride which is not normally a product of chlorination, and chloroform, which is a disinfection by-product; the role of free radical scavengers in protecting the human body; the difficulties of extrapolating experimental results from rodents to humans; the awareness of the complex relationship between governments, chemical industries, special interest groups and the public. Also introduced are the aetiologies of some cancers (e.g., Hepatitis B and C viruses as the instigators for hepatocellular carcinoma) to juxtapose claims that chloroform in drinking water is the sole culprit responsible for liver, bladder, colorectal cancers and birth defects etc. Other well known human carcinogens and a few inorganic compounds known to cause harm are also depicted. Lastly, a structured approach towards integrating the overarching concepts in the analysis of alleged carcinogenicity is applied to chloroform and the inferences discussed.The literature reviewed spanned the years 1848 – 2017.

Published: June 2017

Deformities of non biting midge larvae’s mouthparts are considered as indicators of environmental degradation that caused by water pollutants like pesticides, heavy metals, organic contaminants etc. The present investigation was aimed to assess the effects of 3 pesticides, viz. Cartap Hydrochloride, Carbofuran and Fipronil on deformities of chironomid larvae of the Rice fields of Village Dhunui; Memari Block-II of Burdwan district in West Bengal. The study area is dominated by the species of the genus Chironomus of chironomid community. Concurrently six (6) species were considered. The average percentage of mouthpart deformities was 14% in all chironomid larvae. Highest degree of malformation was noticed in Chironomus circumdatus in which more than 18.90% of all specimens were affected. However, further investigative efforts are essential to investigate the actual explanation in support of the occurrence of high degree of deformities in chironomid.
The Effectiveness of a Blended Strategy based on Concept Mapping and Text Structure in Enhancing EFL Learners’ Writing Performance
Authors: Kassem Hassan Mohammed
Published: June 2017

The current study investigated the effect of a blended strategy based on concept mapping and text structure on EFL learners’ writing performance. An intact group (N = 42) of seventh level English majors at Thadiq Sciences and Humanities College, Shaqra University, KSA participated in the study in the first semester of the academic year 2016-2017. They were assigned to an experimental group and a control group, each consisting of 21 students. A writing pretest was administered to the two groups and scored by two raters using the Weir’s TEEP attribute writing scale (1990). An independent samples t-test performed on the pretest mean scores of the two groups showed that they were homogenous prior to the experiment. Concept mapping and text formatting (the proposed blended strategy) were integrated in the Advanced Writing course (Eng 413) for experimental group students. The control group received conventional instruction that did not include the proposed strategy. Independent and paired samples t-tests revealed that the experimental group outperformed the control group in all the sub-scales of Weir’s TEEP attribute writing scale, hence supporting the positive effect of concept mapping and text formatting on EFL learners’ writing performance. Pedagogical implications are offered.
The Eye of the Beholder: Voyeurism and Surveillance in Williams’s Speaker/Reader Matrix
Authors: Praitis Irena
Published: June 2017

This article underlines how Williams explores a range of ideologies associated with observation, inviting readers to consider how ideological frames of reference impact what we see. Williams’s work on seeing and the positioning of the viewer is here aligned with the work of painters, Degas in particular, occasionally positioning the viewer as an observer, a voyeur, of people unaware of that observation. Williams’s poem “The Young Housewife,” is analyzed for its voyeuristic frames of reference, while the power dynamics of seeing and surveillance are examined in Paterson through Williams’s inclusion of the Cress letters. The article considers Williams’s relationship to such dynamics and asks what we sacrifice when we cease to question the parameters of surveillance and the potential abuses of power associated with it.

Los Matagalpa: indígenas en pie de lucha
Authors: Castro Arias Omar Santiago
Published: June 2017

La lucha indígena en Nicaragua, posee grandes matices en toda su historia.  Cuando se habla de pueblos originarios  los primeros nombres que surgen en el imaginario de las personas son: Subtiava,  Monimbo y grupos étnicos de la Costa Caribe. Este artículo da a conocer a uno de los grupos posiblemente más antiguos y con una no muy clara procedencia étnica. Ubicados en el Centro-Norte del territorio nacional, los Matagalpa como pueblo indígena poseen una estructura, que funciona con dos autoridades, la tradicional y una administrativa, ambas ejercen un trabajo  liderazgo que articula el trabajo político-administrativo y lo canaliza en los territorios a través de la autoridad tradicional y ancestralmente según sus estatutos. La cultura Matagalpa es una de las más importantes en el desarrollo histórico del territorio Nicaragüense. Son conocidos como indios flecheros,  por protagonizar a lo largo de su historia rebeliones e insurgencias en diferentes acciones armadas en defensa de sus derechos. Es así que el arco y la flecha se han convertido en símbolo de resistencia y defensa del territorio. En la actualidad la lucha por la tierra, el respeto y reconocimiento a sus creencias,  incursión en la toma de decisiones  en  gobiernos localesson demandas conducidas por el pueblo indígena como un compromiso histórico con cada mujer y hombre indígena. Las representaciones sociales mestizas castigan de forma negativa al indígena: ser líder e indígena no es digerible para los centros de poder local, y con esta realidad la familia se aferra a sus procesos de luchas para consolidar el frente único y mantener la resistencia indígena con sus mecanismos de liderazgo y gobernanza en cada territorio para el bienestar común.
Comparing Mediation Role of Cultural Intelligence and Self-Efficacy on the Performance of International Business Negotiation
Authors: Thi Hong Lam Nong , Liaw Shu-Yi
Published: June 2017

The study examines the direct and mediating effects of personality factors of Vietnamese negotiators on international business negotiation performance. The theory is developed regarding the three elements: Quality of communication experience, cultural intelligence and negotiation self-efficacy. This study found that quality of communication experience has a strongly positive impact on the performance. Cultural intelligence and negotiation self-efficacy have strongly mediating effects on the performance. Additionally, cultural intelligence and negotiation self-efficacy have reciprocal positive effects. Overall, this study concludes that the tested personality factors have a significance effect on the performance of Vietnamese negotiators in international business negotiation. Therefore, negotiators should focus on enhancing more experience in communication, this is vital and the first priority factor which negotiators need to gain and improve. Furthermore, they have to improve their level of cultural intelligence through accumulating more cultural knowledge and behavior interaction with unfamiliar cultural backgrounds. Cultural intelligence appears to be an indispensable factor in an international context which helps negotiators to deal with cultural barrier issues effectively. Finally, negotiation self-efficacy is important to obtain a better performance which will be ameliorated along with the support of quality of communication experience and cultural intelligence.
Effectual Gold Nanoprobe Sensor for Screening Horse Adulteration in Meat Products

Published: June 2017

A gold nanoparticle (AuNP) probe strategy for testing meat authenticity was developed, which relies on the colorimetric differentiation of a particular DNA sequence, due to the differential aggregation profiles exhibited by the AuNPs in the presence or absence of specific target hybridization. Gold nanoparticles were conjugated with thiolated oligonucleotides for specifically identifying a 69 bp fragment of the horse cytochrome b gene. In the presence of a complementary target preventing aggregation of the AuNPs when acid was added, the reaction mixtures retained the original pink colouration of the colloidal particles, whereas they turned purple in the opposite event. Fresh meatballs, prepared using pure bovine meat, were used as blanks, producing a purplish coloured solution with a peak at ≥570nm. Horse meat was used as positive control and the pink colour obtained after hybridization exhibited maximum absorption at 524 nm. Both the specificity and sensitivity of the tests performed were 100%. Visual observations and spectroscopic data indicated that the coloration produced by the AuNPs (positive-pink, negative-purple) was very stable, showing no change under normal laboratory conditions. The use of AuNPs for the colorimetric detection of DNA targets from undeclared species in meat products provides an inexpensive and easy-to-perform alternative to common molecular assays. The technology described here can be further developed to accommodate detection of many cases of adulteration and fraudulent practices.

Consumers’ increasing concerns toward nutrition, health, and sustainable food have influence food industry. Practitioners in the meat product industry and retailers are focusing on premium labeled meat products, such as Certified Angus Beef and grass-fed beef, to meet consumers’ demand. Although many consumers assume the premium has better taste and texture, there is little research comparing the sensory attributes of the premium and non-premium burgers. This study compared the sensory attributes of three different hamburger patties: flame broiled pre-cooked beef (non-premium, standard patties), Angus beef, and grass-fed beef patties (premium patties). The results show that participants prefer pre-cooked hamburger patties significantly than Angus and grass-fed patties in initial taste and flavor. Also, this pre-cooked hamburger patties are significantly preferred compared to grass-fed patties in overall quality and overall liking attributes. Other sensory attributes, such as appearance, texture, juiciness, and seasoning, show no significant difference among three different patties. This indicates that the pre-cooked hamburger patties can be preferred than (or compatible to) Angus or grass-fed patties.

Levels of aluminium, arsenic, cadmium, chromium, copper, iron, mercury, manganese, nickel, lead and zinc in tap water, groundwater-fed protected spring and bottled water were determined. The cancer and non-cancer risks associated with ingestion of heavy metals (HM) were also assessed for both children and adults. Forty seven water samples obtained from five divisions of Kampala city were analyzed using atomic absorption spectrophotometry. Cancer and non-cancer risks were determined using incremental lifetime cancer risk (ILCR) and non-carcinogenic hazard quotient (HQ), respectively. Lead content was higher than permissible limits (PL) according to East African Standard, World Health Organization, European Union and United States Environmental Protection Agency (USEPA). Arsenic showed minor exceedances above guideline values in tap water and groundwater-fed protected spring, whereas mercury, manganese and nickel were higher than PL. Levels of aluminium, cadmium, chromium, copper, iron, and zinc were below the PL. The lifetime risk of developing cancer through the oral route was greater than the USEPA acceptable level for both children and adults, revealing that exposure to HM in drinking water posed an unacceptable potential cancer risk. Arsenic contributed ca. 90% of the ILCR in tap water and groundwater-fed protected spring. The combined non-cancer risk of the HM expressed as hazard index (HI) was greater than one, with values for children being higher than those for adults. Lead contribution towards HI was in all cases above 90%. These results demonstrate the presence of alarming non-cancer risks for children.
Key Factor of Graphene Localization on Electrical Conductive Properties of Graphene Filled Polyethylene/Polypropylene Composites during Melt Blending
Authors: Tu Ce , Nagata Kenji , Yan Shouke
Published: June 2017

The effect of surfactant-exfoliated graphene (SEG) on the morphology of SEG-filled polyethylene (PE)/ polypropylene (PP) blends has been investigated by image analysis of transmission electron microscope. The electrical conductivity of SEG-filled PE/PP composites strongly depends on the localization of SEG. From theoretical considerations of a previous paper by one of the authors, it is found that the transfer dynamics as well as the stability of different solid nano-fillers at the blends interface reveals a strong dependence on the nano-filler’s aspect ratio. The appropriate control of processing conditions and the selective localization of SEG in the PE/PP composites are key tools to design conducting polymer composites. When the selective localization of SEG is optimized at the PE/PP blends interface, the electrical conductivity reaches 1.86 × 10-5 S/m for a low percolation at 1 wt %, in sharp compared to 7 wt % if the localization of SEG has not been optimized.
Introducción a un método para la conducción y análisis de diálogos didácticos basado en la evaluación de modelos mentales
Authors: Aliberas Joan , Gutiérrez Rufina , Izquierdo Mercè
Published: June 2017

Hemos desarrollado un método de análisis y conducción de diálogos didácticos en las clases de ciencias utilizando como marco teórico el modelo ONEPSI (ONtológico, EPistemológico, PSIcológico). También hemos usado el mismo método tanto en la regulación de un diálogo entre profesor y alumno, como en su posterior análisis. La regulación, efectuada mediante la técnica teachback, basada en el trabajo de Pask, se ha mostrado plenamente compatible con el modelo ONEPSI, y ha mostrado su efectividad tanto para conseguir que el alumno identifique sus dificultades y sea capaz de superarlas, como para lograr que termine razonando de manera compatible con el conocimiento científico. Finalmente se discuten algunas de las posibles consecuencias de su utilización en las clases de ciencias de ESO.
Simulaciones computacionales en la enseñanza de la física: una revisión crítica de los últimos años
Authors: Velasco Juan , Buteler Laura
Published: June 2017

Numerosos artículos fueron publicados en el campo de las simulaciones computacionales en los últimos veinte años. Sin embargo, la extensión de esta área y la diversidad de resultados dificultan la iniciación en ella. A pesar de la existencia de algunas revisiones en simulaciones computacionales, no resultan iluminadoras ya que los aspectos metodológicos son excluidos. Con el fin de atender estas necesidades, se realiza una revisión bibliográfica de investigaciones sobre simulaciones computacionales en enseñanza de la física de los últimos diecisiete años. La información se clasificó de acuerdo con categorías según las características de las investigaciones recabadas. Los resultados muestran una fuerte tendencia de los artículos por analizar el impacto que tiene la utilización de simulaciones en el desempeño de los estudiantes. Se destacan diversos puntos de consenso y disenso en la comunidad para los principales temas en discusión.
Un esquema de transformación lineal: construcción de objetos abstractos a partir de la interiorización de acciones concretas
Authors: González Rojas Doris Evila , Roa Fuentes Solange
Published: June 2017

En este artículo se expone un modelo cognitivo denominado por la teoría APOE (acrónimo de Acción, Proceso, Objeto, Esquema) descomposición genética, que describe las estructuras y mecanismos mentales que un individuo debe desarrollar para comprender el concepto de transformación lineal. Se analiza cómo la definición funcional de la transformación lineal, su representación matricial y geométrica se relacionan a través del concepto de base ordenada. El esquema descrito a través de las diferentes relaciones entre estructuras y mecanismos mentales señala la importancia de realizar acciones sobre objetos concretos (representaciones gráficas de funciones del plano en él mismo) para lograr objetos abstractos. Este modelo permite la construcción de un esquema que puede evolucionar gracias a las diferentes experiencias de un individuo con situaciones matemáticas más sofisticadas.

Life of Polish community abroad is hard to define, due to globalization and another process, which are creating the culture and civilization reality. Polish immigrants in the Netherlands are the representatives of specific migration waves. Young Polish emigration come to the Netherlands thanks to job agencies. Polish immigrants works in agriculture, architecture or they are self-employed. In Dutch people opinion Polish immigrants are considered to be drinkers, bad drivers, people, who don’t speak Dutch. 30% of Dutch society have skeptic view of Polish immigrants. In 2014 28% of European citizens are Polish.
