Secure Group Message Transfer Stegosystem
Authors: Bhatia Mahinder Pal Singh , Bhatia Manjot Kaur , Muttoo Sunil Kumar
Published: May 2016

Grid environment is a virtual organization with varied resources from different administrative domains; it raises the requirement of a secure and reliable protocol for secure communication among various users and servers. The protocol should guarantee that an attacker or an unidentified resource will not breach or forward the information. For secure communication among members of a grid group, an authenticated message transferring system should be implemented. The key objective of this system is to provide a secure transferring path between a sender and its authenticated group members. In recent times, many researchers have proposed various steganographic techniques for secure message communications. This paper proposes a new secure message broadcasting system to hide the messages in such a way that an attacker cannot sense the existence of messages. In the proposed system, the authors use steganography and image encryption to hide group keys and secret messages using group keys in images for secure message broadcasting. The proposed system can withstand against conspiracy attack, message modification attack and various other security attacks. Thus, the proposed system is secure and reliable for message broadcasting.
Growth and Knowledge Management Strategy of Indian Commercial Banks
Authors: Datta Nitish
Published: May 2016

In this paper the author derived short run and long run optimum growth paths from short run and long run growth frontiers using Data Envelopment Analysis (DEA) and investigated the contributing growth factors for all banks also banks segregated into different groups both in short run and long run perspective. The author's short run as well as long run findings strongly support the role knowledge capital as an important contributor to augment growth for all categories of banks. Knowledge capital forces the firms to adopt heterogeneous strategies results in heterogeneity in performance caused by barriers to imitation and inability of the firms to change the dynamic resource endowments quickly. On the contrary the finding supports the view that firm specific dynamic capabilities acquired through efficient knowledge management acts as a strategic variable for influencing performance of Indian commercial banks.
Dielectric Properties Measurement of Biological Materials Using Non-Destructive Sensors
Authors: Aouabdia N. , Belhadj-Tahar N. E. , Alquié Georges.
Published: May 2016

The authors' research work has for objective the study of a sensor with planar resonator for applications in the non-destructive control. In this context, two approaches were defined. In a first part, a conception, a modeling, a simulation with commercial software (HFSS, CST), a realization and measurements were treated on Rectangular Patch Resonators (RPR). The proposed theoretical analysis is based on the Moment Method (MoM) via the Galerkin's approach, in which three types of entire domain basis functions are used to expand the patch currents. While, the first two types of basic functions involve a set of sinusoidal cavity modes without edge conditions (sbf-wo-ec) and with edge conditions (sbf-w-ec), and in order to incorporate the edge conditions (cp-ec), the third one consists of Chebyshev polynomials combinations with weighting factors. These last ones as well as the Green Dyadic spectral functions are efficiently implanted with compact Fortran 90 codes. Two EM commercial software HFSS and CST was used to validate the proposed RPR prototypes. The exactness of the obtained results is estimated using four prototypes operating near 6 GHz, taking into account only the fundamental mode resonant frequency. The theoretical model is compared with the simulations and the measurement results. The second approach of the authors' work which is developed in this paper is focused on the characterization of biological materials in vitro using the RPR prototypes proposed as applicator in the non-destructive control and the medical domain to find the abnormalities of these tissues such as: eczema, psoriasis, cancer, etc. The authors' center of interest will be managed towards the dielectric properties of the biological material to extract the relative permittivity and the loss factor on several samples (liver, fat, chicken, butter, foie gras, etc.).
Parallel Skyline Computation Exploiting the Lattice Structure
Authors: Endres Markus , Kießling Werner
Published: May 2016

The problem of Skyline computation has attracted considerable research attention in the last decade. A Skyline query selects those tuples from a dataset that are optimal with respect to a set of designated preference attributes. Since multicore processors are going mainstream, it has become imperative to develop parallel algorithms, which fully exploit the advantages of such modern hardware architectures. In this paper, the authors present high-performance parallel Skyline algorithms based on the lattice structure generated by a Skyline query. For this, they propose different evaluation strategies and compare several data structures for the parallel evaluation of Skyline queries. The authors present novel optimization techniques for lattice based Skyline algorithms based on pruning and removing one unrestricted attribute domain. They demonstrate through comprehensive experiments on synthetic and real datasets that their new algorithms outperform state-of-the-art multicore Skyline techniques for low-cardinality domains. The authors' algorithms have linear runtime complexity and fully play on modern hardware architectures.

Authors: Reddy G. P.
Published: May 2016

In order to know the impact of improved water management practices a study was conducted at Balipatna block under canal irrigation command to know the economic feasibility of water management through field channels. Data from 30 farmers practicing irrigation through field channels and 30 farmers who are irrigating fields without field channels were collected with help of specially designed questionnaire. In order to know the impact of field channels, a multiple stepwise regression analysis with dummy variable to catch impact of field channels was done. The results indicated that irrigation through field channels had positive impact on the yield of kharif paddy. The variables like application of fertilizers, irrigation cost, seed and labour cost had significant positive impact on the paddy yields. The marginal productivity of inputs indicated fertilizers and seeds are not efficiently utilized compared other inputs. Hence, extension should be under taken to improve application of fertilizer in a more scientific way and encourage the use of yielding varieties to improve yields of paddy.
Knowledge sharing-based strategic roles of subsidiaries of multinationals in China
Authors: Amarasinghe S. T. C. , Yunshi M.
Published: May 2016

In this study, multinational enterprise was conceptualized as an integrative unit for making localized knowledge global. Knowledge base of a Multi National Corporation was basically categorized into two groups; local and global knowledge according to accessibility of corporate units to the knowledge of the corporation rather than its location. It is argued that strategic roles of subsidiaries within the same MNC can differ in terms of magnitude and nature of involvement in sharing with the global knowledge base of the corporation. The paper moves away from the unidirectional flow of knowledge. Based on the knowledge sharing patterns, a four-cell classification matrix was developed to illustrate different strategic roles of subsidiaries. The cluster analysis revealed that there is a significant inter-subsidiary difference in knowledge sharing patterns of subsidiaries. The study shows the strategic active subsidiary as a special case of the problems of managing spatially separate knowledge sources.
Adapting crop varieties to environments and clients through decentralized - participatory approach
Authors: Gunasekare M. T. K.
Published: May 2016

Since 1990s, participatory approaches have became a driving force for agricultural research and rural development. The participatory approach in crop improvement involves the client-farmer in the cultivar selection or breeding and highly appropriate for increasing food security and improving livelihoods of subsistence farmers in developing countries. This has developed over the past decades as an alternative and complementary breeding approach to formal plant breeding to effectively address the needs of the farmers, especially in marginal or resource poor areas. In pursuit of this concept, this paper discusses the trends, advantages and challenges in this approach highlighting the contemporary evidence of success case studies commissioned by various authorities worldwide. While successful experiences are evident, the potential of such applications are still to be explored. Among the key challenges to the approach, this article pays attentions especially to technical, economic and institutional challenges that need to be overcome to integrate end-users based participatory approaches into the formal plant breeding systems. The paper concludes by describing synergies that can potentially be achieved by linking centralized and decentralized plant breeding models over biotechnological methods.

Authors: Weerasinghe S. S. , Siriwardana A. U.
Published: May 2016

The present study was conducted with the objective of producing more suckers from mother stems of pineapple as planting materials. They were sliced and raised in a sand media for 4 - 5 weeks till they force out suckers from lateral buds. These suckers were maintained in a secondary nursery till they reach the transplanting maturity. Thereafter these suckers were split across the epical bud and the resulted halves were established in a nursery. The suckers developed from the split halves were subjected for further multiplication by repeated splitting and following the same procedure. Survivability of the stem slices was 76% and each produced 3 – 5 suckers from lateral buds. After four months 35% of halves produced suckers with epical buds whereas, 65% produced more suckers with lateral buds. Accordingly, with stem slices and two multiplication cycles using lateral suckers a single stem can result 1050 suckers in 16 months. All the suckers formed in this technique are suitable for planting as these suckers derived from axillary buds located at the leaf bases of the stem. Therefore, fast propagation technique is an effective technique can easily be practiced by the pineapple growers.

Authors: Najim M. M. M. , Lee T. S. , Haque M. A. , Esham M.
Published: May 2016

As Asian rice demand is projected to increase by 30% in 2010, a sustainable approach of rice production has become important. In order to fulfill the rice demand for the growing population and with the target rice self-sufficiency of 65%, Malaysia has to increase its rice productivity. As the attainment of sustainability in rice farming is country and area specific, Malaysia has devised its own ways to achieve this goal within a prescribed time frame. The major problems faced by the rice sector have been identified and step-by-step solutions are sought through policy changes. Rice estates in Malaysia have already proven that commercial rice production is viable, economical and sustainable. FELCRA Seberang Perak, the first and largest rice estate in Malaysia, has proven the sustainability and viability of commercial rice farming by achieving a continuous cropping intensity of 200%. The keywords to sustainable rice production are doubling yields, estatization and private corporate sector investments. The strategies to be devised must include getting investments to make the present non-lucrative business a profitable venture, whilst balancing the country’s social obligation.

Authors: Dube Zorodzai
Published: May 2016

In view of the aftermath of the Afrophobic attacks in South Africa, this study regards Paul�s emphasis concerning common humanity and morality as a possible lacuna towards strengthening Ubuntu. Paul taught that both the Jews and the Gentiles have their common ancestor � Adam, and that good morality is a better identity marker than ethnicity. In view of the aftermath of the Afrophobic attacks in South Africa, this study suggests that similar arguments can be used to amend the Ubuntu social canopy.Intradisciplinary and/or interdisciplinary implications: This study is interdisciplinary in nature in that it uses perspectives from social sciences to seek solutions towards a more inclusive communityKeywords: Afrophobia; Xenophobia; Ubuntu; Social Canopy; Christ-like Anthropology

Authors: Berkenbrink Cordula , Hentze Luise , Wurpts Andreas
Published: May 2016

Abstract. The design height of coastal protection structures in Lower Saxony / Germany is determined by the design water level and the corresponding wave run up. For the calculation of these parameters several mathematical models are used which need to be verified for the conditions at the East Frisian Wadden Sea area. For this issue a wave measuring programme is operationally run, which includes various measurement locations and devices around the islands Norderney and Juist. The measurements are continuously extended and adapted in order to improve models and measurements. This paper shows a comparison between measured and calculated data for the storm surge of the 10.–11.01.2015 incorporating to new wave and water level gauges operated within COSYNA as well as a second research project dealing with wave attenuation behind barrier islands. Water levels within the investigation area were calculated by hydrodynamic models driven with a wind field originating from weather forecast and compared to water level measurements. The corresponding wave energy field was calculated by means of a third generation wave model and results compared to measurements of several devices located around the barrier Islands. The aim of the study shown here is to give a brief overview of possible error sources for model-data as well as data-data comparisons.
Mapping Information Literacy and Written Communication Outcomes in an Undergraduate Nursing Curriculum: A Case Study in Librarian-Faculty Collaboration
Authors: Miller Mindi , Neyer Linda
Published: May 2016

A syllabi study was conducted by the health science librarian and nursing faculty members in a baccalaureate nursing program to map information literacy and communication learning outcomes. Nursing course syllabi and assignments were examined for particular evidence of information literacy and communication learning outcomes in relationship to three sets of standards from the American Association of Colleges of Nursing and the Association of College & Research Libraries, and the rubrics of the Association of American Colleges & Universities. A crosswalk was created between the standards to identify areas where the librarian and nursing faculty could better collaborate to assist students in their achievement of these standards. The resulting analysis led to a change in the librarian’s practices with greater involvement with the nursing department. Information literacy skills are needed in a growing number of professions that value evidence-based practice, thus suggesting that similar curriculum mapping projects are useful for other academic disciplines. This project was supported by the Bloomsburg University Teaching and Learning Enhancement (TALE) Pedagogy-Related Research Grant.

Participação política em contextos de alta vulnerabilidade social: estudo exploratório em uma comunidade de Porto Alegre, Brasil
Authors: Costa Pedro de Almeida
Published: May 2016

This paper is under the field of Social Social studies and aims to discuss if the apparent political apathy of a socially vulnerable community is a condition to be overcome or if such condition means an inability to dialogue with the cultural matrix values ​​from which come modern Western rationality and its concepts. This questioning is made from the dialogue between empirical data from an ethnographic research with two years' duration, held in a community with such characteristics, and theoretical foundation which seeks to discuss what could be the causes of a perverse reproduction of unequal conditions in a country of peripheral modernity, especially from the notion of undercitizenship. The initial reflections on this subject point out that such a concept can explain, even in part, the difficulty of people in becoming effective political actors capable of fighting and demand change in its own condition, despite public policies designed to overcome this condition.

Authors: Morini Cristiano
Published: May 2016

This work focuses on the competitiveness seen by the customs procedures involved. Customs can be considered as a bottleneck in international logistics in some countries. Through an exploratory and bibliographical research, we could understand the main characteristics of the customs procedures in Brazil compared with the characteristics of countries considered as world reference. The analysis was based on information drawn from websites of the customs administrations of the countries that initiated the implementation of internationally accepted "good practices’, according to criteria of the World Bank and other international organizations. It is crucial to note the best practices and benchmarking in the customs environment. Among the best practices observed, we highlight the electronic transmission of data, the analysis of risk based on prior information, cooperation at various levels, the use of information technology in transmission and registration procedures, compliance with the Revised Kyoto Convention, among others. Brazil has some actions targeted at best practices, but we need greater agility and coordination in the implementation of most of them.

Published: May 2016

The study on tourist behavior has aroused increasing interest in the areas of consumer behavior and sustainability, since this is seen as an agent that directly influences the sustainability of the destination. In light of environmental psychology, specifically the SOR of Mehrabian and Russell (1974) model, it is understood that the tourist can be influenced by stimuli in the environment. Apprehends that environmental stimuli, represented by features and other information concerning the dimensions of sustainability, arranged in a tourist destination, corresponding to the variables that can influence the behavior of tourists. In this sense, this essay proposes to discuss the relationship between the characteristics of sustainable tourism destinations and tourist behavior. It is believed that the tourist destination can stimulate behaviors towards sustainability, provided that it can properly utilize the characteristics of the environment to inform and educate tourists, especially those related to the dimensions of sustainability. The paper also proposes a framework in an attempt to better understand the relationship discussed and subsequent empirical studies suggest that share the same intent.

Authors: Vogel Gabriel , Azevedo André Filipe Zago
Published: May 2016

Nowadays, there is an intense debate about the process of reprimarization of Brazilian exports and its effects on the economy. This paper aims at contributing to this debate, aiming at identifying the technological intensity of Brazilian and its main states exports, between 2000 and 2010, to its main destinations. The study is based on secondary and official data, provided by the Ministry of Development, Industry and Foreign Trade (MDIC).  The results show that in this period, despite the increase in total exports, there was a drop in the share of high and medium-high technological intensity products on total exports, with a concentration of exports on low technological intensity and primary products, corroborating the hypothesis of the continuation of reprimarization of exports, observed originally in de 1990s. This situation was also observed in all main export states. With regard the states export destination, there was a high share of commodities and low intensity products in total exports to China, while Mercosur showed a higher concentration on medium-high and high technological products.

Published: May 2016

The present study aims at investigating disclosure practices from a sustainability point of view in major Brazilian companies according to guidelines by GRI, Global Reporting Initiative. Additionally, disclosure is verified by taking into consideration the nature of company activities in relation to their potential for environmental impact, according to disposition by law number 10.165/2000. In order to do that, there was a qualitative research with an analysis of content of sustainability reports by 33 companies which published GRI reports in the 2009-2010 period. The results showed a high level of disclosure with a highlight on companies considered to have great potential for pollution. Besides that, it was perceived that the social indicators are the ones that provide companies with the most opportunities to talk over their practices towards collaborators and society while economic and environmental indicators proved more objective, being generally presented as illustrations. It is possible to identify the companies’ search for market legitimacy, since it is through the announcement of such information that these companies display their main measures towards the improvement of people’s lives as well as environmental preservation, which directly affect their image before stakeholders.

This study aimed to examine the relationships between the bases of the constructs Organizational Commitment and Organizational Entrenchment. For this, we carried out a survey of a quantitative character with 392 servers administrative staff of a Federal University, to which a questionnaire containing validated scales for the Brazilian context was applied. Data were analyzed using correlation analysis to verify the relationship between the constitutive dimensions of the two constructs. The main results showed a moderate correlation of instrumental and normative bases of commitment revealing the ambiguity surrounding the definition of these bases proposed by Meyer and Allen (1991) model. The bases instrumental and affective showed low correlation reinforcing the idea that it should not be treated as two dimensions of the same construct. Moreover, affective commitment was not correlated with the entrenchment, showing that they are separate bond. These results support the proposal that the commitment must be treated as a unidimensional construct (restricted to affective base), while the instrumental or continuing base shall be considered a separate construct called organizational entrenchment.

Archaeological Survey Data Quality, Durability, and Use in the United States
Authors: Wilshusen Richard H. , Heilen Michael , Catts Wade , de Dufour Karyn , Jones Bradford
Published: May 2016

High-quality archaeological surveys and data are vital to preservation planning and mitigation efforts. Federal and state historic preservation offices (SHPOs) are accumulating and reviewing more data at an ever-faster pace. Given the critical nature of this information, a SAA task force was charged with assessing current survey practices and concerns. Our review indicates that survey policies and archaeological standards have improved substantially over the last two decades, but SHPOs remain challenged by insufficient professional training for field archaeologists, the need for standardization and integration of new technologies in field work, reporting, and review, as well as the sheer quantity and variety of digital data. A number of analytical tools and metrics are available to assess data quality, but seemingly there is not time or money for states to evaluate how to improve existing and future survey data. We draw upon a survey of SHPOs, a review of current literature, and our own experience to assess archaeological survey quality, data utility and durability for current and anticipated future uses. We offer suggestions on how to move forward, including consideration of an e-106 system for streamlining transfer and exchange of digital data and upgrading current approaches to survey and planning.

Are you an avid fan of Instagramed excavation finds, or YouTube clips of archaeologists? Ever visited an archaeologically-themed virtual museum? Or have you taken a tour of a historic site with a mobile app as your guide? Have you searched for the best Minecraft games deployed in the name of heritage? Or are you regularly on the lookout for blogs to keep you up-to-date on new archaeological thinking?

Beginning with our next issue, Advances in Archaeological Practice (AAP) will become the first major archaeological journal in the English-speaking world to to regularly review the highs and lows, the practicalities, personal experiences and audience impacts of the full range of digital media applied to our discipline. Moving beyond standard book or exhibition reviews, here we will explore any (and all) current digital initiatives produced to engage both general and specialist audiences. Our concern is to push on the boundaries of the review format, turning it into a space where the increasing array of digital outputs being developed and marketed in archaeology are compared and subjected to critical reflection.

Published: May 2016

A sensor chip design for the V-trench biosensor, which is an instrument for highly sensitive fluorescence assay, was investigated to increase its sensitivity. A simulation based on the transfer matrix method revealed that the vertex angle and electric field enhancements of the V-trench biosensor chip are increased by employing a high-refractive-index material for the chip. It was proved that a chip made of high-refractive-index glass for press molding exhibited a 1.4-fold larger electric field enhancement than that made of polystyrene. Influenza virus detection was also demonstrated using glass chips, and a detection limit of 104 pfu/mL was obtained with a sample volume of 15 µL.
Toward physiological indices of emotional state driving future ebook interactivity

Published: May 2016

Ebooks of the future may respond to the emotional experience of the reader. (Neuro-) physiological measures could capture a reader’s emotional state and use this to enhance the reading experience by adding matching sounds or to change the storyline therewith creating a hybrid art form in between literature and gaming. We describe the theoretical foundation of the emotional and creative brain and review the neurophysiological indices that can be used to drive future ebook interactivity in a real life situation. As a case study, we report the neurophysiological measurements of a bestselling author during nine days of writing which can potentially be used later to compare them to those of the readers. In designated calibration blocks, the artist wrote emotional paragraphs for emotional (IAPS) pictures. Analyses showed that we can reliably distinguish writing blocks from resting but we found no reliable differences related to the emotional content of the writing. The study shows that measurements of EEG, heart rate (variability), skin conductance, facial expression and subjective ratings can be done over several hours a day and for several days in a row. In follow-up phases, we will measure 300 readers with a similar setup.
Empreendedorismo por estilo de vida: estudo exploratório sobre fatores motivacionais, características e gestão
Authors: Ribeiro Artur Tavares Vilas Boas , Krakauer Patricia Viveiros de Castro
Published: May 2016

Esse artigo tem como proposta compreender o empreendedorismo por estilo de vida, temática contemporânea e considerada de fronteira do conhecimento, dada a não homogeneidade entre os estilos de empreendedores e a consequente falta de convergência de dados empíricos. Considerado como um tipo que nasce do contexto da atualidade, o empreendedorismo por estilo de vida considera o empreendedor em sua individualidade e o negócio por ele iniciado voltado para a paixão pela própria atividade em si, e não apenas para o propósito financeiro como ocorre com outros empreendimentos. A partir de tal percepção, questiona-se quais as motivações e características de gestão de indivíduos que se engajam em um projeto com esta natureza, objetivando comparar as motivações e características listadas na literatura para esse estilo com as encontradas através da pesquisa de campo. Trata-se de um estudo exploratório, qualitativo que utilizou como método o estudo de caso único. Selecionou-se para o estudo a Worldpackers, por ser uma empresa nova e aderente, à luz da teoria investigada, ao lifestyle entrepreneurship. Os principais resultados mostraram que a principal motivação para o engajamento das pessoas é o envolvimento com a proposta do negócio e várias características foram elencadas, entre elas: a criatividade, habilidade para lidar com conteúdo e situações novas e curiosidade para se aprofundar em temas multidisciplinares.

Objectives

The purpose of this study was to systematically investigate the feasible echocardiographic views for human transthoracic cardiac shear wave elastography (SWE) and the impact of myocardial anisotropy on myocardial stiffness measurements.

Methods

A novel cardiac SWE technique using pulse inversion harmonic imaging and time‐aligned sequential tracking was developed for this study. The technique can measure the quantitative local myocardial stiffness noninvasively. Ten healthy volunteers were recruited and scanned by the proposed technique 3 times on 3 different days.

Results

Seven combinations of echocardiographic views and left ventricular (LV) segments were found to be feasible for LV diastolic stiffness measurements: basal interventricular septum under parasternal short‐ and long‐axis views; mid interventricular septum under parasternal short‐ and long‐axis views; anterior LV free wall under parasternal short‐ and long‐axis views; and posterior LV free wall under a parasternal short‐axis view. Statistical analyses showed good repeatability of LV diastolic stiffness measurements among 3 different days from 70% of the participants for the basal interventricular septum and posterior LV free wall short‐axis views. On the same LV segment, the mean diastolic shear wave speed measurements from the short‐axis view were statistically different from the long‐axis measurements: 1.82 versus 1.29 m/s for the basal interventricular septum; 1.81 versus 1.45 m/s for mid interventricular septum; and 1.96 versus 1.77 m/s for the anterior LV free wall, indicating that myocardial anisotropy plays a substantial role in LV diastolic stiffness measurements.

Conclusions

These results establish the preliminary normal range of LV diastolic stiffness under different scan views and provide important guidance for future clinical studies using cardiac SWE.

Friedel–Crafts reactions of phloroglucinol and anthracene with terephthaldehyde and the varying content of 4, 4′‐bis ((chloromethyl)‐1, 1′‐ biphenyl) (BCMB) yielded novel hypercross‐linked polymers (HCPs). The polymer matrix carries rigid, conjugated, quinonoid blocks; they are tiny semiconducting graphene sheets, whose organization creates micropores. The reaction involves Friedel–Crafts alkylation and the subsequent dehydrogenation of ‐CH2‐ and –CH‐ bridges by the catalyst, FeCl3. Heating the reaction product between 500 and 600°C completes dehydrogenation of residual bridges. Their FTIR spectra and DRS UV‐Vis spectra confirm such results. As a result of heating, the absorption maximum shifted toward longer wavelength, and absorbance was raised. It absorbs light like semiconducting graphene covering the entire ultraviolet, visible, and partly near infrared region. The band gap of synthesized materials is close to 1.2 eV. All the HCPs are amorphous and showed CO2 capture close to 6 wt% at room temperature. The obtained materials are hydrophobic and decompose above 300°C in air atmosphere. So, in addition to its application to sorption of CO2, they are also the right choice of materials for the fabrication of organic solar cells.

TiO2 greatly enhances the densification of Al2O3 in the initial and intermediate stages of sintering, but there is a slight difference between the final densities (97%‐98% of the theoretical value) of undoped and TiO2‐doped Al2O3 sintered at 1600 °C for 1 h. MgO has inappreciable influence on the shrinkage rate of alumina in the same stages, but the resultant density is 99%.

The catalytic activity of nonstoichiometric Pb and Bi ruthenates having the pyrochlore or a related structure in the electrooxidation of olefins is found to be not related to the ability to exchange lattice oxygen, but is associated with the presence of a Ru(V) surface state, which can be oxidized to Ru(VI) at higher potentials.
