1D Atmosphere Models from Inversion of Fe i 630 nm Observations with an Application to Solar Irradiance Studies
Authors: Cristaldi Alice , Ermolli Ilaria
Published: May 2017

Present-day semi-empirical models of solar irradiance (SI) variations reconstruct SI changes measured on timescales greater than a day by using spectra computed in one dimensional atmosphere models (1D models), which are representative of various solar surface features. Various recent studies have pointed out, however, that the spectra synthesized in 1D models do not reflect the radiative emission of the inhomogenous atmosphere revealed by high-resolution solar observations. We aimed to derive observation-based atmospheres from such observations and test their accuracy for SI estimates. We analyzed spectropolarimetric data of the Fe i 630 nm line pair in photospheric regions that are representative of the granular quiet-Sun pattern (QS) and of small- and large-scale magnetic features, both bright and dark with respect to the QS. The data were taken on 2011 August 6, with the CRisp Imaging Spectropolarimeter at the Swedish Solar Telescope, under excellent seeing conditions. We derived atmosphere models of the observed regions from data inversion with the SIR code. We studied the sensitivity of results to spatial resolution and temporal evolution, and discuss the obtained atmospheres with respect to several 1D models. The atmospheres derived from our study agree well with most of the 1D models we compare our results with, both qualitatively and quantitatively (within 10%), except for pore regions. Spectral synthesis computations of the atmosphere obtained from the QS observations return an SI between 400 and 2400 nm that agrees, on average, within 2.2% with standard reference measurements, and within −0.14% with the SI computed on the QS atmosphere employed by the most advanced semi-empirical model of SI variations.
Discovery of a Luminous Radio Transient 460 pc from the Central Supermassive Black Hole in Cygnus A
Authors: Perley D. A. , Perley R. A. , Dhawan V. , Carilli C. L.
Published: May 2017

We report the appearance of a new radio source at a projected offset of 460 pc from the nucleus of Cygnus A. The flux density of the source (which we designate Cygnus A-2) rose from an upper limit of <0.5 mJy in 1989 to 4 mJy in 2016 (ν = 8.5 GHz), but is currently not varying by more than a few percent per year. The radio luminosity of the source is comparable to the most luminous known supernovae, it is compact in Very Long Baseline Array observations down to a scale of 4 pc, and it is coincident with a near-infrared point source seen in pre-existing adaptive optics and HST observations. The most likely interpretation of this source is that it represents a secondary supermassive black hole in a close orbit around the Cygnus A primary, though an exotic supernova model cannot be ruled out. The gravitational influence of a secondary SMBH at this location may have played an important role in triggering the rapid accretion that has powered the Cygnus A radio jet over the past 107 years.
Quantifying Supernovae-driven Multiphase Galactic Outflows
Authors: Li 李 Miao 邈 , Bryan Greg L. , Ostriker Jeremiah P.
Published: May 2017

Galactic outflows are observed everywhere in star-forming disk galaxies and are critical for galaxy formation. Supernovae (SNe) play the key role in driving the outflows, but there is no consensus as to how much energy, mass, and metal they can launch out of the disk. We perform 3D, high-resolution hydrodynamic simulations to study SNe-driven outflows from stratified media. Assuming the SN rate scales with gas surface density Σgas as in the Kennicutt–Schmidt relation, we find that the mass loading factor, η
m, defined as the mass outflow flux divided by the star formation surface density, decreases with increasing Σgas as

. Approximately Σgas ≲ 50 M
⊙ pc−2 marks when η
m ≳ 1. About 10%–50% of the energy and 40%–80% of the metals produced by SNe end up in the outflows. The tenuous hot phase (T > 3 × 105 K), which fills 60%–80% of the volume at the midplane, carries the majority of the energy and metals in the outflows. We discuss how various physical processes, including the vertical distribution of SNe, photoelectric heating, external gravitational field, and SN rate, affect the loading efficiencies. The relative scale height of gas and SNe is a very important factor in determining the loading efficiencies.
Program Outcomes Assessment Method for Multi-Academic Accreditation Bodies: Computer Science Program as a Case Study
Authors: Abdeljaber Hikmat Awad Mohammad , Ahmad Sultan
Published: May 2017

In educational community, assessment process focuses on learning, teaching and outcomes. It provides information for improving learning and teaching. Therefore, a well-established assessment process plays a vital role for improving program outcomes which, in turn, results in fulfilling program educational objectives. However, such a process entails setting well-defined courses learning objectives, program outcomes, and program educational objectives. In addition, an effective assessment method is needed for measuring the extent that program outcomes meet academic accreditation body criteria. This measurement is performed by mapping courses learning objectives with program educational objectives passing through program outcomes. Such mapping for just one academic accreditation body is a straightforward process and involves no complications. However, a coherent assessment method is required for multi academic accreditation bodies. The approach of mapping program outcomes across criteria of multi academic accreditation bodies is likely a promising key for addressing this issue. The proposed assessment method along with the assignments and practices used for evaluating students’ performance such as quizzes and exams, and the associated action plans and recommendations for improvements are crucial steps for the overall assessment process. Findings based on the results of samples taken from a number of students for some courses of computer science program show the flexibility and effectiveness of the proposed assessment method.
Strengthening Oral Language Skills in Mathematics for English Language Learners Through Desmos® Technology
Authors: Caniglia Joanne C , Borgerding Lisa , Meadows Michelle
Published: May 2017

A major focus of teaching English Language Learners (ELL) in mathematics classrooms is to provide multiple opportunities for students to use authentic language. Barrier games offer ELLs a balance between productive (speaking, writing) and receptive (listening, reading) language. In a barrier game, students work in pairs to complete an information gap activity where learners are missing the information they need to complete a task and need to talk to each other to find it. With Desmos®’ Polygraph program, students are provided online tools for transforming informal language into formal language similar to a Barrier Game. Following a background of barrier games in mathematics, this article will provide a detailed description of Polygraph and its potential for all students to learn and apply authentic mathematical language.
Post-Extractivism: From Discourse to Practice—Reflections for Action
Authors: Acosta Alberto
Published: May 2017

The predominant school of thought leads us to believe that an economy without growth is an impossibility and that the only means of achieving development is through economic growth. In turn, this growth requires ever-larger amounts of natural resources to sustain increasing global demand, while generating revenue for the global South to overcome its ‘underdevelopment’. Reality nevertheless tells us that moving beyond this vision is the most pressing challenge of our time: to overcome ‘the religion of economic growth’ and make room for new approaches that will enable us to escape the extractivism ‘trap’. This chapter proposes to move towards a non-capitalist society inspired by the visions, values, experiences and practices of the different forms of buen vivir that can be found among diverse indigenous populations across our planet.

The Optimal Checkpoint Interval for the Long-Running Application
Authors: Zhai Yongning , Li Weiwei
Published: May 2017

For the distributed computing system, excessive or deficient checkpointing operations would result in severe performance degradation. To minimize the expected computation execution of the long-running application with a general failure distribution, the optimal equidistant checkpoint interval for fault tolerant performance optimization is analyzed and derived in this paper. More precisely, the optimal checkpointing period to determine the proper checkpoint sequence is proposed, and the derivation of the expected effective rate of the defined computation cycle is introduced. Corresponding to the maximal expected effective rate, the constraint of the optimal checkpoint sequence can be obtained. From the constraint of optimality, the optimal equidistant checkpoint interval can be obtained according to the minimal fault tolerant overhead ratio. By the numerical results, the proposal is practical to determine a proper equidistant checkpoint interval for fault tolerant performance optimization.
We are the Game Changers
Authors: Arnab Sylvester , Morini Luca , Green Kate , Masters Alex , Bellamy-Woods Tyrone
Published: May 2017

This paper discusses the first iteration of Game Changers Programme hosted by Coventry University's Disruptive Media Learning Lab (DMLL), an open game design initiative. The Programme had the goal of facilitating new models of teaching and learning, new practices in cross-faculty learning/collaboration to make game design and development more culturally open and accessible to staff, students and the broader informal communities surrounding the University. The paper will discuss the theoretical foundation of the GameChangers Programme, grounded in a conceptualisation of design as a holistic, modular and creative process, and in an ethos of sharing, collaborating and remixing. The paper will present the outline of the Course and the Community that constituted the core elements of the Programme, and discuss a plural showcase of a variety of outcomes from the GameChangers Community, focusing on the Programme's cultural impact and on how the Programme as a whole disrupted established notions of game based pedagogy, and the customary hierarchical relations between producers and users of learning games.

Authors: Otarkhani Ali , Shokouhyar Sajad , Pour Sajad Salehi
Published: May 2017

A gap exists in the extant literature on linking information technology governance vis-à-vis hospital performance. Specifically, this work offers insights to fill this gap by adopting the COBIT 5 framework and ISO 38500 standards in examining the relationship between IT governance principles and balanced scorecard (BSC) dimensions of hospital performance. The proposed study investigated the influence of IT governance on Tehran's hospitals' performance. Data were gathered and analyzed from fifty-three (53) questionnaires administered to Health Information Systems (HIS) professionals and IT managers. Results showed that all IT governance dimensions have a positive correlation with hospital performance and IT governance has a significant positive impact on Tehran's hospitals' performance.

Published: May 2017

This paper presents the concept of including the energy cost as a part of the total cost of manufacturing using machining processes in the development of computer aided process plans. The research objective is to index and evaluate the process plans based upon the energy consumption of the machining operations while considering machining cost and to rank or index the process plans based on energy consumption for purposes of decision support in process plan selection. The paper also discusses energy evaluation of process plans and their subsequent effectiveness in terms of overall cost associated with the utilization of effective machining parameters. The MPSEL system, which is an expert system based application, was used to develop alternative process plans. The MACH program, which is a spreadsheet based system, was used to determine the cost associated with machining. The developed process plans are compared based upon the cost associated with utilized energy and machining.
Establishing A-Priori Performance Guarantees for Robot Missions that Include Localization Software
Authors: Lyons Damian , Arkin Ronald C , Jiang Shu , O'Brien Matthew J , Tang Feng , Tang Peng
Published: May 2017

One approach to determining whether an automated system is performing correctly is to monitor its performance, signaling when the performance is not acceptable; another approach is to automatically analyze the possible behaviors of the system a-priori and determine performance guarantees. Thea authors have applied this second approach to automatically derive performance guarantees for behavior-based, multi-robot critical mission software using an innovative approach to formal verification for robotic software. Localization and mapping algorithms can allow a robot to navigate well in an unknown environment. However, whether such algorithms enhance any specific robot mission is currently a matter for empirical validation. Several approaches to incorporating pre-existing software into the authors' probabilistic verification framework are presented, and one used to include Monte-Carlo based localization software. Verification and experimental validation results are discussed for real localization missions with this software, showing that the proposed approach accurately predicts performance.
A Conceptual Framework for Rock Data Integration in Reservoir Models Based on Ontologies
Authors: Garcia Luan Fonseca , Graciolli Vinicius , De Ros Luiz Fernando , Abel Mara
Published: May 2017

In the domain of E&P petroleum chain, the authors have developed a study and proposed a conceptual framework for inserting direct rock data into reservoir models, through calibration of well logs. This type of data is often ignored or manual processed in actual petroleum reservoir modeling activities, due to its high cost of acquisition, or due to the high complexity for its modeling, interpretation and extrapolation. Direct rock data is the data that is acquired by direct observation of the rock, like descriptions of well cores, instead of indirect data, like seismic, well logs, etc. Directly observed data is important because it allows calibration of indirect interpretation methods, detection of errors in their evaluations and also to verify rock properties that is not possible when using indirect data. The authors claim that a well defined ontology can help in describing reservoir petrofacies, which are aggregates of rock data that can be detected through a special signature in the registers of indirectly collected rock data and, therefore, they can use to integrate rock data in reservoir models.
Overcoming Conflict Between Religious and Cultural Freedom and Women's Rights in Africa
Authors: Essien Essien D.
Published: May 2017

Scholarship is generally divided between those who view female circumcision as a religious ritual to be observed, and those who consider the practice as cruel and human right abuse. This lends credence to the ethical question: what should be done when the exercise of the rituals of female circumcision, which is central to African Traditional Religion, entails transgression of fundamental rights? Relying on John Rawls' model and rights based approach. This study examines African religious landscape characterized with this disagreement. With an insight provided into understanding this conflict, a criterion on what should constitute an appropriate interaction is thus supplied.
Corporate Social Responsibility: An Integrative Approach in the Mining Industry
Authors: Alves Maria do Céu Gaspar , Rodrigues Margarida Maria Mendes
Published: May 2017

The mining industry has a huge environmental and social impact in the country/region where is located, consequently its contribution for sustainable development has been widely discussed. Corporate social responsibility (CSR) represents a challenge for this industry, namely, its inclusion as a common management practice integrated in the company´s management control system. For such, it´s imperative that there is a balance between the economic, environmental and social company's concerns. The aim of this article is to study that challenge in a Portuguese subsidiary belonging to a Japanese economic group. The data were collected through interviews and document analysis. The results suggest that CSR practices are not integrated in the management control system, are not part of a long-term environment strategy, and only reflect compliance with Portuguese legislation. It is expected, with this study, to contribute for the literature enrichment about CSR in multinationals companies operating in the extractive industry.

Published: May 2017

There has been increasing recognition that for regional competitiveness in rural areas there needs to be a focus on sustainable farming initiatives especially for family farms that are competing with global conglomerates. Family farms, whilst declining in number, are the purpose of this paper studying the rural entrepreneurship in family farms as they are at the heart of rural communities and the overall agricultural industry and comprise a high percentage of total farms. This paper takes a case study approach using in-depth semi structured interviews to delve into the types of entrepreneurial strategies that are distinctive of family farms in terms of their sustainability approach to farming. Dairy farms in the West Victorian area of Australia are studied and the findings suggest that family farms can increase their regional competitiveness and international standing by focusing on their collaborative, social and sustainable entrepreneurial strategies.
The Library Big Data Research: Status and Directions
Authors: Xu Shaochun , Du Wencai , Wang Chunning , Liu Dapeng
Published: May 2017

Libraries are widely used by government, universities, research institutes, and the public since they are storing and managing intellectual assets. The library information directly stored in libraries and about the people interaction with libraries can be transformed into accessible data which then will be used by researchers to help library better serve users. Librarians need to understand how to transform, analyze, and present data in order to facilitate such knowledge creation. For example, the challenges they face include how to make big datasets more useful, visible and accessible. Fortunately, with new and powerful analytics of big data, such as information visualization tools, researchers/users can look at data in new ways and mine it for information they intend to have. Moreover, interaction of users and stored information has been taken into librarian's consideration to improve library service quality. In this work, the authors discuss the characteristics of datasets in library and argue against a popular confusion that data involved in library research is not big enough, conduct a review for the research work on library big data and then summarize the applications and research directions in this field. The status of big data research in library in China is discussed. The challenges associated with it are also discussed and explored.
Scaling Up Software Birthmarks Using Fuzzy Hashing
Authors: Tsuzaki Takehiro , Yamamoto Teruaki , Tamada Haruaki , Monden Akito
Published: May 2017

To detect the software theft, software birthmarks have been proposed. Software birthmark systems extract software birthmarks, which are native characteristics of software, from binary programs, and compare them by computing the similarity between birthmarks. This paper proposes a new procedure for scaling up the birthmark systems. While conventional birthmark systems are composed of the birthmark extraction phase and the birthmark comparison phase, the proposed method adds two new phases between extraction and comparison, namely, compression phase, which employs fuzzy hashing, and pre-comparison phase, which aims to increase distinction property of birthmarks. The proposed method enables us to reduce the required time in the comparison phase, so that it can be applied to detect software theft among many larger scale software products. From an experimental evaluation, the authors found that the proposed method significantly reduces the comparison time, and keeps the distinction performance, which is one of the important properties of the birthmark. Also, the preservation performance is acceptable when the threshold value is properly set.
Understanding the Mediation Effect of Cloud Computing Adoption in Indian Organization
Authors: Raut Rakesh , Priyadarshinee Pragati , Jha Manoj
Published: May 2017

The aim of this paper is to measure the business performance by taking Cloud computing adoption as a mediating variable in Indian industries. A conceptual model is framed using the concept of a TAM-TOE framework which is combined with some new constructs of ‘Risk'. Partial and full mediation are used from the umbrella concept of SEM (Structural Equation Modelling) to test the hypotheses. The study identified that Technological variables ‘Technology Innovation (TI)' and ‘Usage of Technology (UT)' positively mediates the relationship, Organizational variable ‘Industry Usage (IU)' negatively mediates the relationship and Environmental variables ‘Management Style (MS)' positively mediates the relationship whereas ‘Trust (T)' has no mediation effect. The ‘Risk' factors ‘Risk Analysis (RA)' positively influences the mediation process and ‘Perceived IT Security Risk (PITR)' has no mediation effect on the dependent variable ‘Business performance (BP)'. The findings of the study have some important implications. As the constructs ‘Risk (Perceived IT Security Risk)' and ‘Trust' have no mediation effect, it implies industries do not give importance on these factors while adopting Cloud computing. Hence, risk and trust resulted as the barriers for technology adoption, and organizations should verify these criteria during Cloud computing adoption of a better performance in the business. The study tests indirect effect and direct effect on business performance considering Cloud computing adoption as the mediating variable.
On the Use of Similarity or Query Languages in Cloud Discovery Based on Ontology
Authors: Guerfel Rawand , Sbaï Zohra , Ben Ayed Rahma
Published: May 2017

Cloud computing is increasingly used so that the number of providers offering services is rapidly increasing. Thus, a need to organize these services and to express relations between them arises. To answer this need, ontologies are used. To query these services, the authors use query languages, such as SPARQL, that return two types of results: either a list of required services, or an empty list. However, the second result is not desired. In fact, if the required service is not available, users want to be offered by a list of similar ones instead of the empty list. It is in this sense that the similarity, which provides more results ranked according to their utilities, is used. This paper first presents the Cloud ontology on which the authors' work is based. It then defines and compares between two Cloud service discovery methods which are: the discovery based on query languages and the discovery based on similarity. To show the efficiency of the search based on similarity, the authors propose a search engine that allows the users to query services using a simple to use interface.
Big Data and Analytics
Authors: Krimpmann Dominik , Stühmeier Anna
Published: May 2017

Big Data and Analytics have become key concepts within the corporate world, both commercially and from an information technology (IT) perspective. This paper presents the results of a global quantitative analysis of 400 IT leaders from different industries, which examined their attitudes toward dedicated roles for an Information Architect and a Data Scientist. The results illustrate the importance of these roles at the intersection of business and technology. They also show that to build sustainable and quantifiable business results and define an organization's competitive positioning, both roles need to be dedicated, rather than shared across different people. The research also showed that those dedicated roles contribute actively to a sustainable competitive positioning mainly driven by visualization of complex matters.

Septic Thrombophlebitis with Persistent Methicillin-Resistant Staphylococcus aureus Bacteremia and de novo Resistance to Vancomycin and Daptomycin
Authors: Koton Yael , Or Zafrir , Bisharat Naiel
Published: May 2017

Persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with significant risk of mortality, especially when it occurs while on appropriate antimicrobial therapy. We herein describe an unusual case of a patient with prosthetic aortic tissue valve, who suffered from central venous catheter related MRSA bacteremia with septic thrombus formation in the superior vena cava. MRSA bacteremia persisted despite removal of the catheter and appropriate antimicrobial therapy including vancomycin, rifampin, and daptomycin. Subsequently, the MRSA strain exhibited de novo resistance to vancomycin, rifampin and daptomycin. Eventually, salvage combination therapy with high dose daptomycin and trimethoprim-sulfamethoxazole was successful and achieved clearance of MRSA bacteremia. The case illustrates the growing complexity of treating MRSA infections.
Sex Differences in High School Athletes' Knowledge of Sport-Related Concussion Symptoms and Reporting Behaviors
Authors: Wallace Jessica , Covassin Tracey , Beidler Erica
Published: May 2017

Context: 

Recent researchers have reported that athletes' knowledge of sport-related concussion (SRC) has increased but that athletes still lack knowledge of all the signs and symptoms of SRC. Understanding the signs and symptoms of SRC and the dangers of playing while symptomatic are critical to reporting behaviors in high school athletes.

Objective: 

To examine sex differences in knowledge of SRC symptoms and reasons for not reporting a suspected SRC to an authoritative figure in high school athletes.

Design: 

Cross-sectional study.

Setting: 

Survey.

Patients or Other Participants: 

A total of 288 athletes across 7 sports (198 males [68.8%] and 90 females [31.2%]).

Main Outcome Measure(s): 

A validated knowledge-of-SRC survey consisted of demographic questions, a list of 21 signs and symptoms of SRC, and reasons why athletes would not report their SRC. The independent variable was sex. Athlete knowledge of SRC symptoms was assessed by having participants identify the signs and symptoms of SRC from a list of 21 symptoms. Knowledge scores were calculated by summing the number of correct answers; scores ranged from 0 to 21, with a score closer to 21 representing greater knowledge. Reporting-behavior questions asked athletes to choose reasons why they decided not to report any possible SRC signs and symptoms to an authoritative figure.

Results: 

A sex difference in total SRC symptom knowledge was found (F286 = 4.97, P = .03, d = 0.26). Female high school athletes had more total SRC symptom knowledge (mean ± standard deviation = 15.06 ± 2.63; 95% confidence interval = 14.54, 15.57) than males (14.36 ± 2.76; 95% confidence interval = 13.97, 14.74). Chi-square tests identified significant relationships between sex and 8 different reasons for not reporting an SRC.

Conclusions: 

High school males and females had similar SRC symptom knowledge; however, female athletes were more likely to report their concussive symptoms to an authoritative figure.

No. 39, 1973) is analysed numerically and a brief comparison is made with the total number of families, genera and species recorded by Bews in his Flora of Natal and Zululand (1921). A number of diagrams illustrating the proportional representation of certain elements of the Flora are provided. The families whose species constitute more than 0 ,5% of the total number of species in Natal, and those genera containing 15 or more species, are tabulated. The marked inverse relationship between numbers of genera and families is illustrated. Brief mention is made of some of the elements contributing to the richness of the flora.
Towards a Classification of the African Acacias
Authors: Ross J. H.
Published: May 2017

Some of the first attempts to subdivide the genus Acacia Mill, as a whole are discussed briefly. Bentham’s work, in which the subdivisions of the genus were for the first time given names, is considered and his two series into which the African species fall are reproduced. The characters employed by various workers to divide the African species into two main groups are mentioned and the advantages of using each of these characters for the first dichotomy in a key are discussed. Recent work on pollen morphology and seedling morphology is correlated with general morphology. A proposal put forward by Guinet to divide Acacia into three large genera on the basis of pollen morphology is briefly discussed. Certain modifications to Bentham's series Vulgares and Gummiferae are suggested.

Relationship value antecedents in the South African automotive component supply chain
Authors: Tolmay Aletta S. , Venter Peet
Published: May 2017

Orientation: Although literature agrees on the importance of ‘relationship value’, the term is still seen as ambiguous and authors fail to agree on its antecedents. Within a challenging global arena, relationship value is believed to result in business retention. It is therefore critical to have a better understanding of this value to ensure business sustainability within supply chains. Literature suggests that relationship value drivers comprise three dimensions, namely a core offering, sourcing process and customer operations.Research purpose: The contribution of the research reported on in this paper is an enhanced conceptual understanding of relationship value and its salient drivers within the South African automotive supply chains.Motivation for the study: Literature invites more research on relationship value and its drivers. Therefore, the research reported on tested the antecedents of relationship value.Research design, approach and method: Relationship value drivers were tested through empirical research within the South African automotive supply chains by means of a path analysis. The research utilised a closed-ended questionnaire, and targeted managers among Tier 1 buyers and asked them about the relationship value traits of their best Tier 2 suppliers.Main findings: It was found that personal interaction, which forms part of the sourcing process, is viewed as the strongest antecedent of relationship value within the South African automotive supply chains, followed by product quality and delivery.Practical/managerial implications: It is suggested that superior supply chain practices within the South African automotive industry might secure business retention. Automotive component suppliers are therefore advised to implement relationship value strategies to promote higher value through personal interaction.
Morphometric Wings Similarity among Sylvatic and Domestic Populations of Triatoma infestans (Hemiptera: Reduviidae) from the Gran Chaco Region of Paraguay

Published: May 2017

Despite sustained efforts for eliminating Triatoma infestans, reinfestation still persists in large part of the endemic area of Chagas disease from the Gran Chaco region. Sylvatic T. infestans populations seem to threat success of control programs of domestic T. infestans. In this study, we analyze whether T. infestans collected after a community-wide spraying were survivors or were immigrants from elsewhere using geometric morphometric tools. We used 101 right wings of female T. infestans captured before and after intervention program carried out in 12 de Junio and Casuarina, villages from Paraguayan Chaco, and in Puerto Casado during presprayed collection. There were no significant differences in wing size of domestic T. infestans between pre- and postspraying populations, and between domestic and sylvatic ones. When shape variables originating from postintervention individuals from 12 de Junio were introduced one by one into a discriminant analysis, the greatest weight (53%) was allocated to the sylvatic group. Furthermore, from the prespraying population, 25% were reallocated as postintervention individuals. Only 11% of the insects were reassigned to other groups Puerto Casado and Casuarina. These results suggest that postspraying individuals appear to have different origins. Half of the postspraying individuals from 12 de Junio were similar to the sylvatic ones and 25% of these were similar to those captured in the prespraying period. This remarkable morphometric wings similarity between sylvatic and domestic populations is new evidence suggesting that they could be highly related to each other in the Paraguayan Chaco; human-fed bugs from sylvatic area also support this.
Entitlement attitude in the workplace and its relationship to job satisfaction and organizational commitment
Authors: Dragova-Koleva Sonya Asenova
Published: May 2017

Background
 This article is focused on the entitlement attitude in an organizational context. Its purpose was to examine the relationship of entitlement and its 3 components (active, passive and revengefulness) with job satisfaction and organizational commitment.

 Participants and procedure
 Two independent studies were conducted to examine the discussed relationships. In study 1 and study 2 there participated respectively 110 and 95 full-time employees from both genders working in public and private organizations. The 30-item Bulgarian version of the Entitlement Questionnaire was used. Job satisfaction measurement included employees’ affective response to their overall job and to various aspects of their job. The three aspects of organizational commitment (affective, instrumental and normative) were measured.

 Results
 Active entitlement had a positive effect on satisfaction with results, satisfaction with supervisor, pay satisfaction and overall job satisfaction. It was not related to organizational commitment. Passive entitlement had a positive effect on satisfaction with tasks, but it correlated negatively with pay satisfaction. Higher level of passive entitlement predicted instrumental commitment. Revengefulness was negatively related to task satisfaction, satisfaction with supervisor and overall satisfaction, and had a negative effect on affective commitment.

 Conclusions
 Different forms of entitlement have a diverse influence on the various aspects of job satisfaction and components of organizational commitment. Active and passive types of entitlement are more adaptive, whereas revengefulness is a maladaptive and dysfunctional attitude.

Evaluating the risk of falling of a geriatric rheumatic patient plays an essential role not only in planning and carrying out the physiotherapeutic process. The consequences of falls may be different and, although they do not always result in serious repercussions such as fractures or injuries, it is sufficient that they generate the fear of falling and cause a significant reduction in physical activity. Assessing functional capacity to define the risk of falling is of utmost importance in the case of patients after joint arthroplasty surgeries. The specificity of rheumatic patient’s falls is determined by numerous factors. It is not always possible to avoid them. However, it becomes vital to include fall prevention in the rehabilitation process as well as to prepare the house for the needs of an elderly person so that they are safe and as self-dependent as possible.
The human body as an energetic hybrid? New perspectives for chronic disease treatment?

Inflammatory response is accompanied by changes in cellular energy metabolism. Proinflammatory mediators like plasma C-reactive protein, IL-6, plasminogen activator inhibitor-1, TNF- or monocyte chemoattractant protein-1 released in the site of inflammation activates immune cells and increase energy consumption. Increased demand for energy creates local hypoxia and lead in consequence to mitochondrial dysfunction. Metabolism of cells is switched to anaerobic glycolysis. Mitochondria continuously generate free radicals that what result in imbalance that causes oxidative stress, which results in oxidative damage. Chronic energy imbalance promotes oxidative stress, aging, and neurodegeneration and is associated with numerous disorders like Alzheimer’s disease, multiple sclerosis, Parkinson’s disease or Huntington’s disease. It is also believed that oxidative stress and the formation of free radicals play an important role in the pathogenesis of rheumatoid diseases including especially rheumatoid arthritis. Pharmacological control of energy metabolism disturbances may be valuable therapeutic strategy of treatment of this disorders. In recent review we sum up knowledge related to energy disturbances and discuss phenomena such as zombies or hibernation which may indicate the potential targets for regulation of energy metabolism.

What Do We Rank When We Rank Colleges? Who Determines How and Who Benefits?: Student Empowerment and the Development of Alternative College Rankings
Authors: Schuler Douglas
Published: May 2017

This article describes the life-cycle thus far about how a class of undergraduates and their professor have been developing a new college ranking approach based on the college's cultivation of civic intelligence. The approach was educational in that we learned by doing what it might take to actually develop a rubric in general (although specifically for ranking colleges). We also found it to be empowering since it was largely a student inspired and directed project. it also fostered critical thinking and social critique based on a bottom-up approach to evaluating orthodox higher education.
Inventing Our University: Student-Faculty Collaboration in Critical University Studies
Authors: Steffen Heather
Published: May 2017

In this article, Heather Steffen reflects on her recent participation in a student-faculty collaborative research project, All Worked Up: A Project about Student Labor, and her experience teaching critical university studies. She considers the questions: What does critical university studies offer to students? What can students contribute to critical university studies? And how might such exchanges lead us beyond scholarship, enable us to build solidarity, and empower us to invent a new university, our university, that serves students, scholar-teachers, and its diverse publics rather than the imperatives of neoliberal capital? Because critical university studies has both scholarly and social justice goals, Steffen argues, we must continually look for ways to connect our research and writing to collective action. Research collaborations involving students, faculty, staff, and community members are not only important sites for learning and teaching, but also for creating the personal relationships, networks, knowledge base, and skills required to build solidarity and enact change in higher education.

Locating the Judge within Sentencing Research
Authors: Roach Anleu Sharyn , Brewer Russell , Mack Kathy
Published: May 2017

Research into sentencing is undertaken from a range of theoretical, disciplinary and methodological perspectives. Each approach offers valuable insights, including a conception of the judge, sometimes explicit, often implicit. Little scholarly attention has been paid to directly interrogating the ways in which different research traditions construct the judge in the sentencing process. By investigating how different research approaches locate the judge as an actor in sentencing, theoretically and empirically, this article addresses that gap. It considers key examples of socio-legal scholarship which emphasise the judge as operating within experiential, emotional and social, as well as legal dimensions. This growing body of research offers a more social, relational and interactive understanding of the judge in sentencing, extending and complementing the valuable, but necessarily limited, insights of other research approaches about the place of the judge in sentencing.

A utilização das plantas para fins medicinais é algo que remota aos primórdios da humanidade. Nas últimas décadas, a utilização de plantas medicinais tem se tornado cada vez mais popular, sendo utilizada com diferentes finalidades tanto em países ricos quanto naqueles considerados pobres. É importante destacar que na área da Veterinária esta realidade não é diferente. Pois, criadores, em muitas partes do mundo, utilizam práticas e saberes populares para prevenir e tratar doenças nos seus rebanhos e animais de estimação. Objetivou-se com esse trabalho avaliar a utilização do Etnoconhecimento e da Etnoveterinária  no município de Catolé do Rocha – PB. Os dados coletados demonstram que os produtores rurais entrevistados, no município de Catolé do Rocha - PB, possuem um significativo conhecimento sobre a utilização das plantas medicinais no tratamento das doenças que acometem os animais. A parte da planta mais utilizada na produção de remédios caseiros é a folha em seu estado verde, para o tratamento de doenças em animais. As plantas medicinais mastruz e limão são mais utilizados entre os produtores rurais. O sumo é a forma mais utilizada na preparação dos remédios caseiros no tratamento das doenças em animais.
