Investigating Online Instructors' Experiences With Constructivist Pedagogy in a Private University
Authors: Beisser Sally R. , Sengstock Chuck A.
Published: June 2018

This study supports the significance of professional development for online instructors to design and develop online courses. Data collection from an e-survey of 100 instructors, a focus group, and review of online course syllabi revealed that instructors who teach fully online courses lack on-going university wide support for training in using the learning management system (LMS) to launch their courses, as well as knowledge of research-based pedagogies such as constructivism, to teach their courses. In particular, instructors want more training and support in order to teach effectively in an online environment. Results include the need for university wide training and support for online instructors, available centralized resources, software training for instructors, especially adjuncts, a course in online pedagogies such as constructivism, peer mentoring for instructors, formal and informal sharing opportunities, and support for the online students themselves.
A Theoretical Framework for IT Consumerization
Authors: Arpaci Ibrahim
Published: June 2018

The chapter provided a comprehensive review of previous studies on the adoption of information and communication technology (ICT). The study further conducted a qualitative study on the adoption of “bring your own device” (BYOD). The study systematically reviewed technology acceptance theories and models such as TAM, TPB, and UTAUT at the individual level and technology adoption theories such as “innovation diffusion theory,” “technology-organization-environment framework,” and “institutional theory” at the organizational level. Thereby, key factors predicting the ICT adoption at the individual, organizational, institutional, and environmental level were identified. A theoretical framework that explains the ICT adoption and the consumerization process was proposed based on the theories. The qualitative data collected by semi-structured interviews with senior-level managers was analyzed using the content analysis. The findings suggested that perceived financial cost, compatibility, privacy, and security concerns were significant factors in predicting the enterprise's adoption of BYOD.
Flexible Orchestration of Tools in E-Collaboration
Authors: Magnisalis Ioannis , Demetriadis Stavros
Published: June 2018

Relevant literature has emphasized the lack of a “tool orchestration” framework in e-collaboration environments (either for work or learning purposes). In this chapter, the MAPIS3 software architecture is suggested as a flexible solution to manage the key problem in tool orchestration, which is the efficient data transfer among various tools used in e-collaboration activities. The proposal is assessed by two case studies of flexible e-collaboration scenarios that cannot be implemented automatically with any known architectures or tools. These scenarios entail transfer and transformation of students' collaboration data through an IMS-LD compatible “player.” The data emerge originally to a specific tool and are transferred to another tool. The overall implementations were evaluated from the developers', the instructors', and the students' perspectives. Results indicate that MAPIS3 supports seamless data flow among tools efficiently and flexibly. In particular, teachers are supported in monitoring the e-collaboration process by flexible visualizations of peer/student interactions.
The Rate of Adoption in Households and Organizations
Authors: Vejlgaard Henrik
Published: June 2018

The aim of this study is to investigate if households or organizations are faster in their adoption of an innovation. There does not appear to be existing research on this area of diffusion of innovations research. In this comparative study, the study object is digital terrestrial television (DTT), specifically the implementation of DTT in Denmark. By taking a service theory approach, DTT can be categorized as a service innovation. The rate of adoption is a concept in diffusion of innovations theory, which is used as the study's theoretical framework. For both units of analysis, three surveys were carried out. Based on the data, the rate of adoption for households and for organizations was established. It is clear that organizations adopt an innovation faster than households during the entire adoption process. Based on this research, a predictive model is constructed conceptually.
Design Optimisation of Internally Reinforced Beams Subjected to Torsion Loading
Authors: Silva Hugo Miguel , de Meireles José Filipe Bizarro
Published: June 2018

In this work, novel types of internally reinforced hollow-box beams were structurally optimized using a Finite Element Updating code built in MATLAB. In total, 24 different beams were optimized under torsion loads. A new objective function was defined in order to consider the balance between mass and deflection on relevant nodal points. New formulae were developed in order to assess the efficiency of the code and of the structures. The efficiency of the code is determined by comparing the Finite Element results of the optimized solutions using ANSYS with the initial solutions. It was concluded that the optimization algorithm, built in Sequential Quadratic Programming (SQP) allowed to improve the effective mechanical. Therefore, the developed algorithm is effective in optimizing the novel FEM models under the studied conditions.

SOURCES: waterborne contamination in the oil sands region
Authors: Gammon P
Published: June 2018

The aim of the Sources Project is to quantify the environmental risks associated with the large extractive Athabasca oil sands industry, including the development of methods to apportion emissions to their original source. To accomplish either of these tasks for
waterborne emissions requires knowing two principle characteristics: the flux (amount) of the emissions and the reactions those emissions undergo within the receiving environment. A Reactive Transport Model (RTM) defines both of these through coupled hydrologic and geochemical models. An RTM is
under development for a wetland test site that is down hydraulic gradient from a large, long?lived oil sands tailings pond (TP). Waterborne emissions enter the test site from the western edge and then flow southward along a preferred conglomeratic subsurface conduit. From the conduit emissions
spread both laterally and rise to the surface then spread laterally into wetland surface environments. The identification and apportionment of these emissions indicates that multiple metals and isotopic signatures identify the extent of the emissions. However, chloride is the traditional ion used to
identify emissions in oil sands monitoring, but it fails to distinguish emissions sources in the test area due to the plethora of potential saline inputs. The geochemical model indicates metal constituents undergo sorption and attenuation along the flow path, with organometallic complexes playing an
important but previously unrecognized role. Fluxes will be calculated once the hydraulic model has completed numerical verification. The organic constituents within emissions, primarily napthanic acids (NAs), are commonly regarded as posing the greatest environmental risk from waterborne emissions.
However, defining their geochemical behaviour in environmental systems remains problematic. To address this issue an experiment was performed to see if biodegradation was attenuating NAs. Biotraps were installed with an isotopically labelled adamantine structured NA. Extracted phospholipids from the
microbes that populated the biotraps demonstrated strong evidence for methanotrophic metabolic pathways, with no evidence the microbiome were biodegrading the NA. This suggests that these adamantine-structured Nas would persist within the Athabasca environment.
The analysis of data errors in financial information databases: New evidence from the Korean financial markets
Authors: Jung Hyung-Chan , Nam Hyun-Jung
Published: June 2018

Background: As financial professionals including policy-makers tend to base decisions on research performed using large machine-readable financial databases, the accuracy of the financial data provided by database companies has a direct impact on the quality of their decisions. Objectives: The objective of this study was to examine data errors in the DataGuide and KisValue databases which are both primary sources of stock prices and return data for Korea Exchange securities in Korea. This article also discussed the methodological implications of erroneous data on monthly stock returns in empirical studies on Korean financial markets. Methods: A cross-checking technique was used in this study. Results: The results suggest that there are material discrepancies between the DataGuide and KisValue databases in monthly stock returns, most of which are attributable to the mishandling of split events and of missing values. The results also indicate that DataGuide provides a more reliable service than KisValue in terms of monthly stock returns. Conclusion: The results show that extreme monthly returns resulting from serious data errors in the DataGuide and KisValue databases may be enough to sharply change the properties of monthly stock return distributions and to over- or underestimate long-term abnormal stock returns.

Published: June 2018

Abstract. With the fast development of seaborne trade and relatively more efforts on reducing emissions from other sources in China, shipping emissions contribute more and more significantly to air pollution. In this study, based on a shipping emission inventory with high spatial and temporal resolution within 200 nautical miles (Nm) to the Chinese coastline, the Community Multiscale Air Quality (CMAQ) model was applied to quantify the impacts of the shipping sector on the annual and seasonal concentrations of PM2.5 for the base year 2015 in China. Emissions within 12 Nm accounted for 51.2 %–56.5 % of the total shipping emissions, and the distinct seasonal variations in spatial distribution were observed. The modeling results showed that shipping emissions increased the annual averaged PM2.5 concentrations in eastern China up to 5.2 μg/m3, and the impacts in YRD (Yangtze River Delta) and PRD (Pearl River Delta) were much greater than those in BTH (Beijing-Tianjin-Hebei). Shipping emissions influenced the air quality in not only coastal areas but also the inland areas hundreds of kilometers (up to 960 km) away from the sea. The impacts on the PM2.5 showed obvious seasonal variability, and patterns in the north and south of the Yangtze river were also quite different. In addition, since the onshore wind can carry ship pollutants to inland areas, the daily contributions of shipping emissions in onshore flow days were about 1.8–2.7 times higher than that in rest of days. A source-oriented CMAQ was used to estimate the contributions of shipping emissions from maritime areas within 0–12 Nm, 12–50 Nm, 50–100 Nm and 100–200 Nm to PM2.5 concentrations. The results indicated that shipping emissions within 12 Nm were the dominant contributor with contributions 30–90 % of the total impacts induced by emissions with 200 Nm. While a relative high contribution (40–60 %) of shipping emissions within 20–100 Nm was observed in the north of PRD region and south of Lianyungang, due to the major water traffic lanes far from land.
Evaluation of cation exchange membrane performance under exposure to high Hg0 and HgBr2 concentrations
Authors: Miller Matthieu B. , Gustin Mae S. , Dunham-Cheatham Sarrah M. , Edwards Grant C.
Published: June 2018

Abstract. Reactive mercury (RM) is an important component of the global atmospheric mercury cycle, but measurement currently depends on un-calibrated, operationally defined methods with large uncertainty and demonstrated interferences and artifacts. Cation exchange membranes (CEM) provide a promising alternative methodology for quantification of RM, but method validation and improvement are ongoing. For the CEM material to be reliable, uptake of gaseous elemental mercury (GEM) must be negligible for all conditions, and RM compounds must be captured and retained with high efficiency. In this study the performance of CEM material under exposure to high concentrations of GEM (1.43 × 106–1.85 × 106 pg m−3) and reactive gaseous mercury bromide (HgBr2 ~ 5000 pg m−3) was explored, using a custom-built mercury vapor permeation system, with quantification of total permeated Hg accomplished via pyrolysis at 600 °C and detection using a Tekran® 2537A. Permeation tests were conducted for 24 to 72 hours in clean laboratory air, with absolute humidity levels ranging from 0.1–10 g m−3 water vapor. Gaseous elemental mercury uptake by the CEM material averaged no more than 0.004 % of total exposure for all test conditions, which equates to a non-detectable GEM artifact for typical ambient air sample concentrations. Recovery of HgBr2 on CEM filters was > 100 % compared to calculated total permeated HgBr2, suggesting incomplete thermal decomposition at the pyrolyzer, as the CEM material collected HgBr2 with less than 1 % downstream breakthrough on average, implying a high collection efficiency.
Estimation of isotope variation of N2O during denitrification by Pseudomonas aureofaciens and Pseudomonas chlororaphis: implications for N2O source apportionment
Authors: Haslun Joshua A. , Ostrom Nathaniel E. , Hegg Eric L. , Ostrom Peggy H.
Published: June 2018

Abstract. Soil microbial processes, stimulated by agricultural fertilization, account
for 90 % of anthropogenic nitrous oxide (N2O), the leading
source of ozone depletion and a potent greenhouse gas. Efforts to reduce
N2O flux commonly focus on reducing fertilization rates. Management
of microbial processes responsible for N2O production may also be
used to reduce N2O emissions, but this requires knowledge of the
prevailing process. To this end, stable isotopes of N2O have been
applied to differentiate N2O produced by nitrification and
denitrification. To better understand the factors contributing to isotopic
variation during denitrification, we characterized the δ15N,
δ18O and site preference (SP; the intramolecular distribution of
15N in N2O) of N2O produced during
NO3- reduction by Pseudomonas chlororaphis subsp. aureofaciens and P. c. subsp. chlororaphis. The terminal product of
denitrification for these two species is N2O because they lack the
gene nitrous oxide reductase, which is responsible for the reduction of
N2O to N2. In addition to species, treatments included
electron donor (citrate and succinate) and electron donor concentration
(0.01, 0.1, 1 and 10 mM) as factors. In contrast to the expectation of a
Rayleigh model, all treatments exhibited curvilinear behaviour between
δ15N or δ18O and the extent of the reaction. The
curvilinear behaviour indicates that the fractionation factor changed over
the course of the reaction, something that is not unexpected for a multi-step
process such as denitrification. Using the derivative of the equation, we
estimated that the net isotope effects (η) vary by as much as
100 ‰ over the course of a single reaction, presenting challenges
for using δ15N and δ18O as apportionment tools. In
contrast, SP for denitrification was not affected by the extent of the
reaction, the electron donor source or concentration, although the mean SP of
N2O produced by each species differed. Therefore, SP remains a
robust indicator of the origin of N2O. To improve apportionment
estimates with SP, future studies could evaluate other factors that
contribute to the variation in SP.
Analysis of the disaster characteristics and emergency response of the Jiuzhaigou earthquake
Authors: Wang Wei , Chen Hong , Xu Aihui , Qu Minhao
Published: June 2018

Abstract. China's earthquake emergency response system has been improved by lessons learned
from multiple earthquakes. This paper focuses on the Ms 7.0
earthquake that occurred in Jiuzhaigou County, Sichuan Province, China, on
8 August 2017 and assesses the emergency response activities of all levels of
government as well as various departments, rescue teams, enterprises and
public institutions and social organizations. The emergency response is
compared to other large earthquakes that occurred in China in recent years.
The lessons learned from these experiences can inform the emergency response
to future disasters. The characteristics of the Jiuzhaigou earthquake and the
emergency responses after the event are analysed. The response level and
resource mobilization were appropriately adjusted as the disaster developed,
and various departments worked together to conduct multi-sector joint rescue
efforts. Additionally, professional rescue forces and participating social
organizations were more rationally mobilized than during past earthquake
emergency responses. A set of effective disaster relief command and
coordination mechanisms was established to facilitate cooperation between
multiple departments and social organizations under the leadership of the
local government. Finally, new and more effective technologies played an
important role in the emergency response and rescue efforts following the
earthquake.
A three year time-series of volatile organic iodocarbons in Bedford Basin, Nova Scotia: a Northwestern Atlantic fjord
Authors: Shi Qiang , Wallace Douglas
Published: June 2018

Abstract. We report weekly observations of volatile organic iodocarbons (CH3I, CH2ClI and CH2I2) over the time-period May 2015 to December 2017 from 4 depths in Bedford Basin, a coastal fjord (70 m deep) on the Atlantic coast of Canada. The fjord is subject to winter-time mixing, seasonal stratification and bloom dynamics, subsurface oxygen depletion, local input of freshwater and occasional intrusions of higher density water from the adjacent continental shelf. Near-surface concentrations showed strong seasonal and sub-seasonal variability which is compared with other coastal time-series. Relationships with other properties lead to the hypothesis that near-surface iodocarbon production is linked to reduction of iodate to iodide under conditions of post-bloom phytoplankton senescence, nutrient stress or viral lysis following seasonal disappearance of nutrients. The vertical variation of CH2I2 and CH2ClI within the upper 10m is consistent with rapid photolysis of CH2I2. Average annual sea-to-air fluxes (62 nmol m−2 day−1) of total volatile organic iodine were slightly higher than observed in other coastal and shelf time-series and polyiodinated compounds contributed 85 % of the total flux. Fluxes were subject to strong interannual variability (2–3X) as a result, mainly, of wind-speed variability. Near-surface net production of CH3I averaged 1.0 pmol L−1 day−1 and was similar to rates in the English Channel but an order of magnitude higher than in shallow waters of the Kiel Fjord, Germany, possibly due to higher microbial degradation in the latter. The near-bottom (60 m) time-series showed evidence for CH3I production associated with organic matter degradation, and a possible switch from production of CH3I via an alkylation pathway to production of CH2I2 by a haloform-type reaction. Near-bottom CH3I production varied strongly between years but was generally ca. 20 times lower than near-surface production. Post-intrusion decreases of iodocarbons at 60 m suggested removal timescales of 14, 65 and 70 days for CH3I, CH2I2 and CH2ClI respectively.

Published: June 2018

Urban revitalization is the process of the city to restore its vibrancy, bringing the city to life, expanding profitable activities, increase in land and economic values and start-up new business ventures. The importance of revitalization can help improve the development to the city in terms of economic, social and cultural. Strategies of revitalization have been implemented through investments, conservation and regeneration that emphasizes to promote tourism, strengthen the capabilities and increase employment opportunities. The aim of this research paper is to revitalize the city of Bandar Seri Begawan into a sustainable environment integrating the interest of residents, businesses and tourists. Subsequently is to investigate the cause and effect of revitalization towards tourism, cultural and social activities. The study focuses on Bandar Seri Begawan, the capital city of Brunei which does not have the usual characteristic of a busy, key economic centre or ‘life’ of a country which suffers from lack of vitality that it loses out to other cities. Interviews and on-site observations methods were used for this study. The findings demonstrate that revitalization of Bandar Seri Begawan is closely related to the Water Village - Kampong Ayer as it represents the identity of Bandar Seri Begawan. This paper highlights the development of a conceptual framework that can be served as guidelines to revitalize the Bandar Seri Begawan (BSB) into a sustainable city environment integrating all the factors – the diversity of needs of residents, tourists and businesses which also help to understand the cause and effect of revitalization towards tourism, cultural and social activities.Socio-Economic Impact of Revitalization: The Case of Bandar Seri Begawan, Brunei Darussalam
Understanding Political – Administrative Relations in Local Governments in Tanzania: A Case of Tanga City Council
Authors: Njunwa Kelvin M.
Published: June 2018

Political-administrative relations are attracting the attention of researchers in the current public administration domain in developing countries. Local governments in Tanzania operate based on two types of officials namely; politicians and administrators and whose performance is largely dependent on the relationship of the two. The purpose of the paper was to provide a clear picture of the political-administrative relation in local governments. The study adopted a case study design by purposefully selecting Tanga City Council. A total of fifty (50) respondents were selected purposefully based on their knowledge and experience in working with the elected officials. The methods of data collection used include, survey method, interview, observation, Focus Group Discussion and Key Focus Interview (KFIs). Qualitative data were analysed using content analysis and quantitative data were analysed using SPSS whereby descriptive statistics were computed. The study revealed that the relationship between the elected and the appointed officials is characterized by conflict, distrust and interference that negatively affect employee’s performance in local government. Further, the study revealed that poor relations is highly associated with conflict of interests, distrust, task interdependence, political interference, lack of education on the side of politicians, poor communication and partisan politics. The study recommends that the government should have a regular monitoring of the relations between the two and encourage cooperation. Also the elected officials need to be trained on how to perform their roles in their areas of jurisdiction. The study recommend further that the elected and the appointed officials should  perform their duties for public interests, increase the level of trust and do away with partisan politics in performing local government functions.
The Impact of Talent Management on Resident Doctor Performance at Jordanian Ministry of Health Educational Hospitals
Authors: Atoom Dirgham Ameen
Published: June 2018

This study aims to identify the impact of talent management on medical physician performance at the Jordan ministry of health educational hospitals. However, the population of study was the resident physicians at the three educational hospitals (Prince HAMZA, Princess BASMA and AL-Karak), and the number of population was (478) male and female doctors, and the study sample consisted of (77) male and female resident physicians at the educational hospitals, forming (16%) of the study population. On the other hand, the two researchers relied on the questionnaire in order to collect data on the study sample, and they relied on the descriptive approach and single and multiple regression to analyze the data. The results of study show the following: that the level of talent management application at the three educational hospitals came with moderate level, and the arithmetic mean for the estimates of sample individuals on resident doctors areas was moderate at large, also, there is a significant statistically impact at (α≤0.05) for the management of talents in its dimensions on the resident physician performance, but with moderate level, also there is impact of talent management on all physician performance dimensions (morning report presentation, doing morning round, examining and admitting the patients at night and evening shift and coordinating with other departments in hospital for diagnostic procedures).So, the study recommended that education hospitals should develop systems and programs to attract, select, develop, evaluate the talent and make available all tools necessary to retain talent physician and keep abreast with modern management thought in talent management practice at the educational Jordanian hospitals.
Review of Strategic Planning Model in Higher Education: The OMC Model
Authors: Pasha Mubarak , Bhupathyraaj Mullaicharam
Published: June 2018

The concept of strategic planning has extensively been used to formulate institutional objectives of higher education institutions into time bound deliverables. Although there is a general agreement on the conceptual note on the strategic planning process, the differences are conspicuous in its internal process of transformation from strategic formulation to implementation. Consequently, models that apply to higher education institutions have been drawn up in the management sciences in the last quarter of the twentieth century. However, the format for institutional review of strategic planning is still in its infancy although its review constitutes a conspicuous phase of institutional planning. The foregoing discussion is intended to prescribe a general format for an institutional review of a strategic planning model. It runs on the hypothesis that the review has three phases, though not mutually exclusive, viz. review of the framework, review of the process, and review of the outcome. The paper under discussion is an attempt to develop a new logical framework for the review of the strategic plan of an educational institution. The model is labelled as the OMC model as it was developed for and subsequently used in Oman Medical College.

Asian Americans are the fastest growing ethnic group in U.S. However, they represent only 1.7% of U.S. cancer clinical trial participants. This pilot study describes findings on barriers, promoters and recommendations related to cancer clinical trial participation from Asian Americans. The research team conducted 3 focus groups comprised of 21 community members and 4 key informant interviews with healthcare providers. Qualitative methodology was used to identify themes about cancer clinical trial participation. Barriers and promoters were categorized based on themes identified and previous study findings. Eight major themes and 5 recommendations were identified from the focus group data. Five major themes and 7 recommendations were identified from the key informant data. Asian Americans’ decision to participate in cancer clinical trials is largely influenced by their cultural values and practices such as altruism and family-based decision making process. Technology platforms provide promising venues to reach Asian Americans. Family-based decision making process, altruism, and the use of technology platforms may need to be considered when outreaching to Asian Americans on cancer clinical trial participation.

Onderzoek naar de mogelijke juridische integratie van de Elektriciteits-, Gas- en Warmtewet en een uniform toezicht op de energiesector

Deze bijdrage geeft de belangrijkste bevindingen weer van een onderzoek naar de vraag in hoeverre integratie van de Nederlandse Gas-, Elektriciteits- en Warmtewet en de stroomlijning van het toezicht hierop mogelijk is. Op basis van de bevindingen van dit onderzoek zijn drie belangrijke conclusies te trekken. Allereerst bestaan grote mogelijkheden tot integratie van de Gaswet en Elektriciteitswet 1998 en de uniformering van het toezicht hierop. Desalniettemin bestaan ook barrières tot integratie. Zo leiden de begripsomschrijvingen van de kernbegrippen tot problemen voor integratie. Dit probleem wordt verergerd door de recente inwerkingtreding van de Europese netwerkcodes door de Europese Commissie, die buiten het bestek van dit onderzoek vallen. Daarnaast bestaan grote verschillen tussen de Warmtewet enerzijds en de Gas- en Elektriciteitswet anderzijds, omdat de bepalingen uit de Warmtewet een gebrek aan vergelijkbare artikelen vertonen. Daarom kan worden geconcludeerd dat de huidige Warmtewet nog niet te integreren is met de huidige Elektriciteitswet 1998 en Gaswet. Ten derde komen de meeste belemmeringen voort uit Nederlands beleid. Dit betekent dat de Nederlandse wetgever de ruimte heeft om de verschillende bepalingen aan te passen en te integreren. Op basis van bovenstaande conclusies en wanneer er speciale aandacht aan het begrippenkader wordt gegeven lijkt het mogelijk om een integrale energiewet met geharmoniseerd toezicht door de Autoriteit Consument en Markt in de elektriciteits- en gasmarkt te creëren, mits de grenzen van het Europees recht en technologische kenmerken van de markten worden gerespecteerd.
Sobre el origen de los derechos naturales en los juristas del siglo XII || On Natural Rights’ Origin in the Jurists of the XIIth Century
Authors: Megías Quirós José Justo
Published: June 2018

RESUMEN: Ha sido frecuente últimamente atribuir a los decretistas del siglo XII la primera formulación de los derechos naturales. Brian Tierney ha situado su origen en las obras de Rufino y Huguccio al comentar la parte “demostrativa” del derecho natural. Esta tesis supondría adelantar su nacimiento a una época dominada por la concepción objetivista del Derecho. Examinamos aquí la concepción del Derecho en los decretistas más importantes de la segunda mitad del siglo XII, Paucapalea, Rufino, Esteban de Tournai, Simón Bisiniano y Huguccio, así como la relevancia que otorgaron estos juristas al Derecho desde una perspectiva subjetiva.
 
ABSTRACT: Recently, it has often been attributed to the 12th century decretists the first formulation of natural rights. In this sense, Brian Tierney placed his origin in the works of Rufino and Huguccio, when they commented on the "demonstrative" part of natural law. This thesis would mean bringing forward his birth to an era dominated by the objectivist conception of Law. We examine here the conception of Law in the most important decretists of the second half of the 12th century (Paucapalea, Rufino, Esteban de Tournai, Simón Bisiniano and Huguccio) as well as the relevance that these jurists gave the law from a subjective perspective
Los derechos humanos en la sociedad del riesgo. Crisis del Estado, justicia intergeneracional y medio ambiente || Human rights in risk society. State crisis, intergenerational justice and environment
Authors: De Julios-Campuzano Alfonso
Published: June 2018

RESUMEN: Esta era de la globalización es, como Beck ha apuntado, la era del riesgo global, que se caracteriza por el creciente nivel de riesgo en el manejo de los medios técnicos que amenaza la preservación del planeta y la supervivencia de la especie. En ese contexto, resulta cada vez más notoria la insuficiencia de un modelo de comprensión de los derechos humanos vinculado a la primera modernidad, que concibió los derechos ligados al marco espacial del Estado-nación y a una concepción de la temporalidad como tiempo presente.  Frente a ello, reivindicamos un nuevo paradigma de los derechos humanos que, a partir de la dimensión global de los problemas y de una concepción intergeneracional de la justicia, trascienda los límites territoriales del Estado e incorpore la dimensión del futuro en la protección de los bienes jurídicos.
 

ABSTRACT: The globalisation era is, as Beck has pointed out, the age of global risk, characterized by the increasing level of risk in the management of technical means. In this context, the insufficiency of a model of understanding human rights linked to the first modernity becomes increasingly evident. Against this, we demand a new paradigm of human rights that, from the global dimension of problems and from an intergenerational conception of justice, transcend the territorial limits of the State and incorporate the dimension of future in the protection of legal assets.

Biological control constitutes one of the world’s prime ecosystems services, and can provide long-term and broad-scale suppression of invasive pests, weeds and pathogens in both natural and agricultural environments. Following (very few) widely-documented historic cases that led to sizeable environmental up-sets, the discipline of insect biological control has -over the past three decades- gone through much-needed reform. Now, by deliberately taking into account the ecological risks associated with insect biological control, immense environmental and societal benefits can be gained. In this study, we document and analyze a rare, successful case of biological control against the invasive mealybug, Phenacoccus manihoti (Hemiptera: Pseudococcidae) which invaded Southeast Asia in 2008, where it caused substantial crop losses and triggered 2- to 3-fold surges in agricultural commodity prices. In 2009, the host-specific parasitoid Anagyrus lopezi (Hymenoptera: Encyrtidae) was released in Thailand and subsequently introduced into neighboring Asian countries. Drawing upon continental-scale insect surveys, multi-year population studies and (field-level) experimental assays, we show how A. lopezi attained intermediate to high parasitism rates across diverse agro-ecological contexts. Driving mealybug populations below non-damaging levels at a continental scale, A. lopezi allowed yield recoveries up to 10.0 t/ha and provided biological control services worth several hundred dollars per ha (at local farm-gate prices) in Asia’s 4-million ha cassava crop. Our work provides lessons to invasion science and crop protection worldwide, heralds a new era for insect biological control, and highlights its potentially large socio-economic benefits to agricultural sustainability in the face of a debilitating invasive pest. In times of unrelenting insect invasions, surging pesticide use and accelerating (invertebrate) biodiversity loss across the globe, this study unequivocally demonstrates how biological control – as a pure public good – constitutes a powerful, cost-effective and environmentally-responsible solution for invasive species mitigation.

Right to equal healthcare is statutory in Norway, but there is little knowledge of immigrant women's experiences of health- and welfare services during pregnancy and the portnatal period. Immigrant women are at higher risk for a number of complications related to this period. The purpose of this study was to acquire deeper insight into immigrant women's needs and experiences during their pregnancy, childbirth and the postnatal period in Norway. The study has a qualitative design using in-depth interviews of immigrant women during pregnancy and the postnatal period. The results are divided into four categories; networks, health professionals have different approaches, the father`s role, and knowledge and information. Results show that language is an important prerequisite for equitable and culture-sensitive health services. Mutual understanding has to be established for the woman's needs to be met and to experience co-determination and recognition. More attention to the father's role is suggested.  equal healthcare; immigrant women; qualitative design; birth; postnatal periodlikeverdige helsetjenester; innvandrerkvinner; kvalitativt design; fødsel; barseltid

Evaluation of relative (allometric) growth provides useful information to understand the development of organisms, as well as to aid in the management of fishery-exploited species. Usually, relative growth analyses use classical models such as the linear equation or the power function (allometric equation). However, these methods do not consider discontinuities in growth and may mask important biological information. As an alternative to overcome poor results and misleading interpretations, recent studies have suggested the use of more complex models, such as non-linear regressions, in conjunction with a model selection approach. Here, we tested differences in the performance of diverse models (simple linear regression, power function, and polynomial models) to assess the relative growth of the trigonal clam Tivela mactroides, an important fishing resource along the South American coast. Regressions were employed to relate parameters of the shell (length (L), width (W), height (H) and weight (SW)) among each other and with soft parts of the organism (dry weight (DW) and ash-free dry weight (ASDW)). Then, model selection was performed using the information theory and multi-model inference approach. The power function was more suitable to describe the relationships involving shell parameters and soft parts weight parameters (i.e., L vs. SW, DW, and AFDW, and SW vs. DW). However, it failed in unveiling changes in the morphometric relationships between shell parameters (i.e., L vs. W and H; W vs. H) over time, which were better described by polynomial functions. Linear models, in turn, were not selected for any relationship. Overall, our results show that more complex models (in this study polynomial functions) can unveil changes in growth related to modifications in environmental features or physiology. Therefore, we suggest that classical and more complex models should be combined in future studies of allometric growth of molluscs.
Multiple Bonding in Actinide Chemistry

Published: June 2018

The field of actinide–ligand multiple bonds has flourished in recent years, with many new types of complexes only first having been isolated within the past decade. The structure and bonding in many of these species highlight the unique chemistry of the actinide elements. Synthetic routes to actinide–ligand multiple bonds are diverse; this article provides an overview of the methods for preparing actinide nitrido, imido, and terminal mono‐oxo compounds, as well as their heavier pnictogen and chalcogen analogs. Carbene complexes of thorium and uranium are also discussed. Many of these classes of compounds tend to display short An–L bonds, providing structural evidence for multiple bond character. Nevertheless, An–L multiple bonds are generally strongly polarized as established by reactivity studies of these often highly reactive species. Calculations have provided additional insight into the nature of the An–L bond with results ranging from strong triple bond character in
trans
‐bis(imido) and nitrido complexes of uranium to substantial ionic interactions in carbene complexes of thorium.
Mössbauer Spectroscopy of Actinide Compounds
Authors: Gaczyński Piotr
Published: June 2018

Mössbauer spectroscopy is a microscopic element‐specific technique that is a well‐established tool for probing aspects of electronic structure, especially those reflected in magnetic properties. Even though the properties of a sample material may well depend on long‐range behavior, Mössbauer spectroscopy does not require the probe atoms or nuclei to be polarized and it hence can be performed in zero applied field. Even so, special external conditions such as high pressure, high magnetic fields, or ultralow temperatures are fairly easily applied. The most distinctive feature of Mössbauer spectroscopy is the possibility to gain rather direct information on the charge state of the resonant atom via the so‐called isomer shift. The needed information is gained by determination of hyperfine interaction energies, that is, the coupling between the electron shell and its nucleus. The signal is given only by solid materials; however, they need not be crystalline, meaning that glasses, frozen solutions, and amorphous solids can be studied. Two examples are presented to demonstrate the power of Mössbauer spectroscopy in the study of magnetic and electronic properties of materials with 5f‐electrons. Both of them are counterparts of superconducting materials. NpFeAsO is a counterpart of a rare‐earth iron oxypnictide, and NpTGa5is a counterpart of the plutonium superconductor PuCoGa5.

Sustainable remediation has been increasingly regarded as a promising alternative in recent years. It considersnet environmental impactssuch as energy use, greenhouse gas emission, and waste reduction. Passivein situremediation or natural attenuation are the key component of sustainable remediation often intended to minimize the net environmental impacts. However, leaving contaminants in the subsurface requires the increased burden of proof to show that plumes are stable and residual contaminants do not pose a significant health risk. Particularly in complex geological environments and for actinide species with complex geochemical behaviors, it is difficult to ensure the system stability as well as to predict the future plume conditions. This article presents recent scientific advances to support sustainable remediation in complex geological systems, including site characterization techniques, hydrological and geochemical model developments, and numerical simulations. In particular, we highlight the recent developments in non‐invasive geophysical characterization as well as computationally efficient geochemical models for describing uranium and other reactive species. We demonstrate this approach using the extensive data and models from the Savannah River Site F‐area, which has been contaminated by low‐level radioactive waste solutions including uranium, tritium, and other radionuclides.
