P6V2G: a privacy-preserving V2G scheme for two-way payments and reputation
Authors: Schwerdt Rebecca , Nagel Matthias , Fetzer Valerie , Gräf Tobias , Rupp Andy
Published: September 2019

The number of electric vehicles (EVs) is steadily growing. This provides a promising opportunity for balancing the smart grid of the future, because vehicle-to-grid (V2G) systems can utilize the batteries of plugged-in EVs as much needed distributed energy storage: In times of high production and low demand the excess energy in the grid is stored in the EVs’ batteries, while peaks in demand are mitigated by EVs feeding electricity back to the grid. But the data needed for managing individual V2G charging sessions as well as for billing and rewards is of a highly personal and therefore sensitive nature. This causes V2G systems to pose a significant threat to the privacy of their users. Existing cryptographic protocols for this scenario either do not offer adequate privacy protection or fail to provide key features necessary to obtain a practical system.

Based on the recent cryptographic toll collection framework P4TC, this work introduces a privacy-preserving but efficient V2G payment and reward system called P6V2G. Our system facilitates two-way transactions in a semi online and post-payment setting. It provides double-spending detection, an integrated reputation system, contingency traceability and blacklisting features, and is portable between EVs. The aforementioned properties are holistically captured within an established cryptographic security framework. In contrast to existing protocols, this formal model of a V2G payment and reward system allows us to assert all properties through a comprehensive formal proof.
State-based load profile generation for modeling energetic flexibility
Authors: Förderer Kevin , Schmeck Hartmut
Published: September 2019

Communicating the energetic flexibility of distributed energy resources (DERs) is a key requirement for enabling explicit and targeted requests to steer their behavior. The approach presented in this paper allows the generation of load profiles that are likely to be feasible, which means the load profiles can be reproduced by the respective DERs. It also allows to conduct a targeted search for specific load profiles. Aside from load profiles for individual DERs, load profiles for aggregates of multiple DERs can be generated. We evaluate the approach by training and testing artificial neural networks (ANNs) for three configurations of DERs. Even for aggregates of multiple DERs, ratios of feasible load profiles to the total number of generated load profiles of over 99% can be achieved. The trained ANNs act as surrogate models for the represented DERs. Using these models, a demand side manager is able to determine beneficial load profiles. The resulting load profiles can then be used as target schedules which the respective DERs must follow.
Distributed multi-objective scheduling of power consumption for smart buildings
Authors: Nebel-Wenner Marvin , Reinhold Christian , Wille Farina , Nieße Astrid , Sonnenschein Michael
Published: September 2019

Load management of electrical devices in residential buildings can be applied with different goals in the power grid, such as the cost optimization regarding variable electricity prices, peak load reduction or the minimization of behavioral efforts for users due to load shifting. A cooperative multi-objective optimization of consumers and generators of power has the potential to solve the simultaneity problem of power consumption and optimize the power supply from the superposed grid regarding different goals. In this paper, we present a multi-criteria extension of a distributed cooperative load management technique in smart grids based on a multi-agent framework. As a data basis, we use feasible power consumption and production schedules of buildings, which have been derived from simulations of a building model and have already been optimized with regard to self-consumption. We show that the flexibilities of smart buildings can be used to pursue different targets and display the advantage of integrating various goals into one optimization process.
Designing an integrated socio-technical behaviour change system for energy saving
Authors: Koroleva Ksenia , Melenhorst Mark , Novak Jasminko , Herrera Gonzalez Sergio Luis , Fraternali Piero , Rizzoli Andrea E.
Published: September 2019

Stimulating households to save energy with behaviour change support systems is a challenge and an opportunity to support efforts towards more sustainable energy consumption. The approaches developed so far, often either; do not consider the underlying behaviour change process in a systematic way, or do not provide a systematic linking of design elements to findings from behaviour change literature and the design of persuasive systems. This paper discusses the design and evaluation of a holistic socio-technical behaviour change system for energy saving that combines insights from behavioural theories and the persuasive system design in a systematic way. The findings from these two streams of research are combined into an integrated socio-technical model for informing the design of a behaviour change system for energy saving, which is then implemented in a concrete system design. The developed system combines smart meter data with interactive visualisations of energy consumption and energy saving impact, gamified incentive mechanisms, energy saving recommendations and attention triggers. The system design distinguishes between a version with non-personalized energy saving tips and a version with personalized recommendations that are deployed and evaluated separately. In this paper, we present the design and evaluation results of the non-personalized system in a real-world pilot. Obtained results indicate reduced energy consumption compared to a control group and a positive change in energy knowledge in the treatment group using the system, as well as positive user feedback about the suitability of the designed system to encourage energy saving.
Trust-less electricity consumption optimization in local energy communities
Authors: Knirsch Fabian , Langthaler Oliver , Engel Dominik
Published: September 2019

Optimizing energy consumption in local energy communities is one of the key contributions to the so-calledsmart grid. Such communities are equipped with rooftop photovoltaic power plants or other forms of small power plants for local energy production. In addition, a number of appliances allow for shiftable energy consumption, e.g., heat pumps or electric vehicle charging stations. The ability to shift is, however, dependent on customer preferences. In this paper, we present a trust-less approach for optimizing the electricity consumption in a local energy community given forecasts of energy production and customer demands, along with constraints for shiftable loads. In larger communities, appointing a single party for managing load curtailment requires a high level of trust. In the proposed trust-less approach, all parties can independently propose optimal solutions for this optimization problem and then globally agree one one solution that meets the defined requirements to the greatest extent.
Why We Care about (Non) fictional Places
Authors: von Mossner Alexa Weik
Published: September 2019

Cognitive ecocriticism draws on research in neuroscience and cognitive narratology to explore how literary reading can lead us to care about natural environments. Ann Pancake’s novel Strange as This Weather Has Been (2007) serves as an example of a novel that cues both direct and empathetic emotions for an actual environment—the Appalachian Mountains—that is wounded and scarred. I argue that the novel’s protagonists allow readers to imaginatively experience what it is like to love an environment and then witness its destruction by mountaintop removal mining. Pancake’s decision to relate large parts of the story through the consciousness of teenagers allows for highly emotional perspectives that have the potential to engage readers in the social and moral issues around resource extraction.
Representations of Students in Composition Scholarship
Authors: Johnson Kristine
Published: September 2019

Using methods from corpus linguistics, the author argues that the practice of making knowledge in composition studies is bound with the discursive act of representing students. Students are represented both in ways that align with disciplinary knowledge about writing and in ways that align with major intellectual shifts in composition studies.
VLA-4 phosphorylation during tumor and immune cell migration relies on its coupling to VEGFR2 and CXCR4 by syndecan-1
Authors: Jung Oisun , Beauvais DeannaLee M. , Adams Kristin M. , Rapraeger Alan C.
Published: September 2019

When targeted by the tumor-promoting enzyme heparanase, cleaved and shed syndecan-1 (Sdc1) then couples VEGFR2 (also known as KDR) to VLA-4, activating VEGFR2 and the directed migration of myeloma cells. But how VEGFR2 activates VLA-4-mediated motility has remained unknown. We now report that VEGFR2 causes PKA-mediated phosphorylation of VLA-4 on S988, an event known to stimulate tumor metastasis while suppressing cytotoxic immune cells. A key partner in this mechanism is the chemokine receptor CXCR4, a well-known mediator of cell motility in response to gradients of the chemokine SDF-1 (also known as CXCL12). The entire machinery necessary to phosphorylate VLA-4, consisting of CXCR4, AC7 (also known as ADCY7) and PKA, is constitutively associated with VEGFR2 and is localized to the integrin by Sdc1. VEGFR2 carries out the novel phosphorylation of Y135 within the DRY microswitch of CXCR4, sequentially activating Gαiβγ, AC7 and PKA, which phosphorylates S988 on the integrin. This mechanism is blocked by a syndecan-mimetic peptide (SSTNVEGFR2), which, by preventing VEGFR2 linkage to VLA-4, arrests tumor cell migration that depends on VLA-4 phosphorylation and stimulates the LFA-1-mediated migration of cytotoxic leukocytes.
Does Cheap Talk Affect Market Outcomes? Evidence from eBay
Authors: Elfenbein Daniel W. , Fisman Raymond , McManus Brian
Published: September 2019

We study cheap talk by firms and responses by their consumers, focusing on unverifiable promises of charitable donations on eBay during 2005–2006. Cheap talk listings have lower sales probabilities but sell at higher prices when successful. The negative relationship between cheap talk and sales is concentrated in the months following Hurricane Katrina, a time when verifiable and unverifiable charity listings increased dramatically. Finally, we show that cheap talk sellers have lower quality ratings than those making verifiable donations. Our results suggest that buyers ( justifiably) avoid cheap talk listings when credible quality signals are available, thus limiting the extent of cheap talk. (JEL D12, D82, D83, L15, L31, M31)
High Trade Costs and Their Consequences: An Estimated Dynamic Model of African Agricultural Storage and Trade
Authors: Porteous Obie
Published: September 2019

Using a new intranational dataset of monthly grain prices and production and a new approach to identify cost parameters, I estimate and solve a dynamic model of agricultural storage and trade covering all 42 countries of continental sub-Saharan Africa. I find median trade costs over five times higher than elsewhere in the world. The potential welfare gains from reducing these costs are substantial, are driven by lower food prices, and can be achieved efficiently by investing in well-targeted trade corridors. A static annual model underestimates trade costs and welfare effects by failing to identify when trade occurs. (JEL F14, O13, O19, Q11, Q13, Q17)
The Local Economic and Welfare Consequences of Hydraulic Fracturing
Authors: Bartik Alexander W. , Currie Janet , Greenstone Michael , Knittel Christopher R.
Published: September 2019

Exploiting geological variation and timing in the initiation of hydraulic fracturing, we find that fracking leads to sharp increases in oil and gas recovery and improvements in a wide set of economic indicators. There is also evidence of deterioration in local amenities, which may include increases in crime, noise, and traffic and declines in health. Using a Rosen-Roback-style spatial equilibrium model to infer the net welfare impacts, we estimate that willingness-to-pay (WTP) for allowing fracking equals about $2,500 per household annually (4.9 percent of household income), although WTP is heterogeneous, ranging from more than $10,000 to roughly 0 across 10 shale regions.(JEL D12, K42, L71, Q35, Q51, Q53, R41)
Dealing with a soft tissue lesion that is scheduled for CT-guided biopsy and that has decreased in size on preprocedural planning CT
Authors: Yakar Derya , Kwee Thomas C
Published: September 2019

On planning CT before CT-guided biopsy, the target lesion may have decreased in size compared to previous imaging. Radiologists frequently face the dilemma of whether to biopsy these shrinking lesions or not. There is currently a lack of literature on how often such a situation is encountered in clinical practice, how it is dealt with, and if the perceived lesion size reduction always implies benignancy. This information would be valuable to develop evidence-based strategies for this specific clinical situation. We aimed to determine the frequency, radiologist’s management, and nature of lesions with size reduction on prebiopsy planning CT. In this retrospective study, we found that the incidence of lesions with size reduction on prebiopsy planning CT was 1.00% (11/1103). Biopsy was refrained from in most cases (9/11). Eight lesions proved to be benign, one malignant, one harboured both benign and malignant pathology, and one lesion remained of unclear nature. Soft tissue lesions with size reduction on prebiopsy planning CT are encountered infrequently and are usually not biopsied. Although most of these lesions are benign, lesion size reduction does not exclude malignancy. Therefore, clinical and imaging follow-up should be considered mandatory when biopsy is cancelled.
An unusual association of ulnar hemimelia with mesoaxial synostotic syndactyly
Authors: Özdemir Meltem , Kavak Rasime Pelin , Kaplanoğlu Hatice
Published: September 2019

Ulnar hemimelia, also referred to as post-axial longitudinal deficiency of the upper limb, is a very rare skeletal anomaly characterized by the partial or complete absence of the ulna. The majority of the reported cases are sporadic and more common in males. The disorder is mostly unilateral, right-sided and incomplete. A slight shortening of the forearm, radial bowing and ulnar-sided hand drift are the anomalies which often accompany ulnar hemimelia. Ulnar hemimelia may also be seen in association with complex wrist and hand anomalies. The absence of post-axial metacarpal and digital bones are frequent findings in patients with this rare disorder. Cases with additional digital abnormalities such as post-axial syndactyly and camptodactyly are also present in the literature. However, a case of ulnar hemimelia in association with mesoaxial synostotic syndactyly has never been reported to date.
Per Se Modality and Natural Implication – an Account of Connexive Logic in Robert Kilwardby

We present a formal reconstruction of the theories of the medieval logician Robert Kilwardby, focusing on his account of accidental and natural inferences and the underlying modal logic that gives rise to it. We show how Kilwardby’s use of an essentialist modality underpins his connexive account of implication.
Class, political economy and loyalist political disaffection: agonistic politics and the flag protests
Authors: Barry John
Published: September 2019

The flag protests in Northern Ireland (2012–13) offer an opportunity on the one hand to examine the politics of dispossession, national identity, decline and political violence in loyalist areas in Belfast. On the other, they are an opportunity to examine of hope, leadership and change within working class loyalism – not least, around the re-imagining of what Britishness can/could or perhaps should mean in post-Agreement Northern Ireland. This article offers an activist-academic perspective on and interpretation of the meaning and potential of those protests around how they reveal both a fracturing and potential for rethinking Britishness. It suggests the possibilities and limits of an inclusive, civic, rather than ethnic, national identity, and a sense of Britishness sufficient to the task of agonistic (as opposed to antagonistic) engagement and contestation with Irish nationalism and republicanism. By antagonistic I mean relations that are characterised in whole or part in terms of ‘friend-enemy’ thus containing within them the possibility of violence, while by agonistic I mean oppositional relations that do not contain this threat of violence. Agonism (from Greek agon, meaning ‘struggle’) emphasises the potentially positive aspects of certain (but not all) forms of political conflict. It accepts a permanent place for such conflict, but seeks to show how we might accept and channel this positively. It is also to affirm the legitimacy of one’s political adversary and their objectives even if one fundamentally disagrees with those objectives. The article argues that an agonistic conceptualisation of democracy and democratic change understood as non-violent disagreement (as opposed to consensus and agreement) is a more accurate and useful understanding than a conceptualisation of democracy and politics as either agreement or antagonism. In this way one can interpret the flag protests as vacillating between a legitimate democratic agonistic politics of struggle and contestation and an illegitimate, reactionary antagonistic politics of violence and threat.
The politics of neoliberalisation and resistance in post-crash Northern Ireland: a reply to Byers
Authors: Johnson Matthew
Published: September 2019

Seán Byers presents a comprehensive overview of the post-crash political landscape in Northern Ireland. His most significant contribution is, perhaps, the most understated: that the Blairite settlement is incapable of resolving the social cleavages that threaten any possibility of harmony. He highlights, again and again, the ways in which apparently divergent actors, such as Sinn Féin and the DUP are brought together through the demands of neoliberal governance and, in so doing, deprive their working class electorates of real change. In this reply, I argue that the current situation highlights the need for genuine transformative politics and that this is most likely to come from Britain, not the Republic.
Una nueva aproximación estadística al problema de homicidios en El Salvador
Authors: Valiente Thoresen Alberto
Published: September 2019

A pesar de la elevada atención prestada a la tasa de homicidios en El Salvador, no se han fundamentado cuantitativamente las correlaciones empíricas de esta variable con otras variables explicativas. Este estudio contribuye a atender esta carencia, calculando regresiones cuantílicas de la tasa de homicidios por 100.000 habitantes por municipio en El Salvador en el percentil 3, 50 y 98 respectivamente, con datos poblacionales de 2007. Los modelos resultantes demuestran que la tasa de homicidios está significativamente correlacionada: positivamente con la cantidad de pandillas por municipio, en el percentil 3 y 50; positivamente con el índice de urbanidad y negativamente con el acceso a agua potable, en el percentil 50; así como positivamente con la cantidad de pandilleros por 100.000 habitantes, en el percentil 98. Estos resultados pueden usarse para orientar las políticas, pero solo explican parte del problema. Urgen mejores estadísticas para subsanar algunas limitantes en futuros estudios.
América del Sur en la Política Exterior Brasileña de Lula Da Silva
Authors: GaviÃo Leandro , Gomes Saraiva Miriam
Published: September 2019

A partir de la idea de que América del Sur ha ocupado un lugar destacado en la política exterior brasileña, este artículo analiza las especificidades de la política externa para la región durante el gobierno de Lula da Silva (2003-2010). A pesar de la línea de continuidad con proyectos iniciados por el gobierno anterior, la gestión de Lula presentó singularidades significativas, derivadas, sobre todo, de la prioridad otorgada a una mayor profundización de los lazos de cooperación y de integración regional en América del Sur, teniendo como principales ejemplos la creación de la unasur y el nuevo impulso experimentado por el mercosur. El artículo analiza las políticas exteriores hacia la región a la luz de la dinámica doméstica con el foco en la reorganización de las fuerzas políticas, y del contexto regional con la emergencia de gobiernos de izquierda y centroizquierda, así como de la aceleración los cambios económicos de los países del entorno. Finalmente, plantea la cuestión de la construcción de una identidad regional.

Специфичным соединением в листьях S. aemiliana является изокверцитрин, не идентифицированный у других близких видов. Хроматографические профили S. aemiliana и S. betulifolia в целом очень сходны. Это является дополнительным доказательством мнения учёных о таксономическом ранге S. aemiliana как подвида, вариации или формы S. betulifolia. По количественному содержанию фенольных соединений S. aemiliana (сумма фенольных соединений варьирует от 16,4 до 23,88 мг/г) более сходна с S. beauverdiana. Листья S. aemiliana содержат много гиперозида (до 9,50 мг/г), что практически в два раза больше, чем у S. beauverdiana (до 4,3 мг/г) и в 6 раз у S. betulifolia  (до 1,55 мг/г). Выявленная разница в содержании гиперозида между тремя таксонами Spiraea статистически достоверна.

Polyphonic Theology of the Fathers/polyphone Theologie der Kirchenväter. Bemerkungen zu einem Konzept und seiner Brauchbarkeit
Authors: Markschies Christoph
Published: September 2019

The contribution is presenting a new focus on the development of Christian theology in Antiquity: the idea of a polyphonic theology of the Fathers. This idea uses the term ›polyphony‹, well established in music theory and in certain forms of Literary criticism and Biblical theology, to describe a certain structured plurality in the concepts of certain individual ancient theologians and in the overall design of Christian theology in Antiquity. The first part gives certain details about the term ›polyphony‹ used to describe forms of thinking, like polyphony in music consists of two or more lines of melody of certain independence (opposed to homophony), the second part asks which new insights one can get using the new idea to analyze ancient Christian literature and the third part deals with certain problems of the approach.
Theodoret of Cyrus. An Access to the polyphonic context of Antiochia
Authors: Bergjan Silke-Petra
Published: September 2019

Polyphonie im Fall Theodorets lässt sich beziehen auf den vielstimmigen Kontext, den wir in seiner Wirkungsstätte Antiochia im 5. Jahrhundert antreffen. Polyphonie kann aber auch das Zusammenspiel der verschiedenen dogmatischen Themen bei Theodoret meinen. Im Folgenden sollen seine Äußerungen zur Providenz Gottes einen Einblick in seine Person geben und eine breitere Perspektive ermöglichen, die aus der Engführung auf cyrillische Themen herausführt. Die Christologie ist für Theodoret Teil der Providenz Gottes. Theodoret äussert sich in drei Schriften zur Providenz Gottes: Graecarum affectionum curatio, De providentia orationes decem und Haereticarum fabularum compendium. Die Texte zeigen, dass es in Antiochia eine Diskussion um die Rede vom Fleisch Christi als Hülle der Gottheit gegeben hat, dass Theodoret hiervon Distanz nimmt und sich ganz auf die Menschwerdung als Annahme der ganzen menschlichen Natur konzentriert.
Impulse aus der Augustinforschung
Authors: Henning Drecoll Volker
Published: September 2019

Research in Augustine is manifold. Recent scholarship in Germany focused upon Augustine‘s heresiology (esp. against Manichaeism, but also Pelagianism, Donatism, Priscillianism), the controversy with Neoplatonism, his exegesis (esp. in sermons and in de Genesi ad litteram), emotions (esp. for the description of sin and grace), and his widespread correspondence. As important impulses for modern theology, his concept of God may be of special interest. God establishes his will in time and history and cannot be urged against his will. This is the presupposition not only for Augustine’s christology and pneumatology, but also for his understanding of history and his doctrine of grace. The latter takes into consideration the social context of human beings, the emotional character of voluntary decisions and the ongoing development of individual identity. Furthermore, good and evil are not equal options, but the good is only possible if God enables the individual to act according to his insights and exerts a direct influence upon one's will. Insights or knowledge are not salvific by themselves, but belong to one’s development that leads to a better understanding of creation and revelation exactly when it is orientated towards God’s salvific operations.

Fast and simple dataset selection for machine learning
Authors: Peter Timm J. , Nelles Oliver
Published: September 2019

The task of data reduction is discussed and a novel selection approach which allows to control the optimal point distribution of the selected data subset is proposed. The proposed approach utilizes the estimation of probability density functions (pdfs). Due to its structure, the new method is capable of selecting a subset either by approximating the pdf of the original dataset or by approximating an arbitrary, desired target pdf. The new strategy evaluates the estimated pdfs solely on the selected data points, resulting in a simple and efficient algorithm with low computational and memory demand. The performance of the new approach is investigated for two different scenarios. For representative subset selection of a dataset, the new approach is compared to a recently proposed, more complex method and shows comparable results. For the demonstration of the capability of matching a target pdf, a uniform distribution is chosen as an example. Here the new method is compared to strategies for space-filling design of experiments and shows convincing results.
Nonlinear dynamic behaviors of outer shell and upper deck structures subjected to impact loading in maritime environment
Authors: Prabowo Aditya Rio , Sohn Jung Min
Published: September 2019

Ship collision appears as the most threatening loading accounting for structural casualties and numbers of casualties after impact on the target ship. In order to avoid such losses against collision, better safety during activities in maritime environment is demanded. Therefore, assessment of ship structure is needed to understand dynamic effect of the impact and quantify nonlinear behavior of local members. This study is conducted to achieve those aims by deploying nonlinear finite element analysis (NLFEA) to idealized ship collision event. Validation of the numerical method is performed by comparing results of a modeled collision case with various empirical calculations. Design for impact loading in main analysis considers side collision to main hull structure, which single side skin (SSS) and double side skin (DSS) types are modeled. Investigation is also directed to influence of the target members on the main hull to capacity of absorbed energy and characteristic of structural resistance. Analysis results indicate that good understanding is successfully obtained in terms of structural damage-energy relation. Confirmation of the current calculation using numerical calculation is also confirmed considering the modeled cases and empirical results agree well. Tendency of hull responses concluded that the longitudinal members contribute more to structural resistance against side collision.
Experimental and simulation investigation on spring-in deformation for L-shape component
Authors: Gajjar Tushar , Shah Dhaval B. , Joshi S. J. , Patel K. M.
Published: September 2019

The angular deformation is key parameter in composite manufacturing for curvature surfaces. Process Induced Distortions (PID’s) are a major problem while manufacturing a composite part using autoclave process. Spring-back or spring-in is one of the PID in autoclave process. Spring-in effect either increase or decrease at angled section during curing of composite laminates. In this paper, L-shaped composite part has been manufactured using autoclave process. The material properties like glass transition temperature, heat reaction, crystallization temperature, Coefficient of Thermal Expansion have been measured for the cured component by using various testing techniques. Spring-in angle has been found for various number of layers and layup orientation. The simulation has been performed in ABAQUS software along with the COMPRO plug-in for each component. The variation of spring-in angle has been observed with changing material properties. The experimental results have been compared with simulation results. The percentage variation of spring-in deformation for experimental and simulation results has been found in the range of 5-7%.
An Investigation into the Underpinning Factors of Plagiarism among Universities in Iran
Authors: Shaghaghi Mahdi , Vasfi Mohammad-Reza
Published: September 2019

We are living in a time where plagiarism is a highly critical issue in the publish-or-perish stage of academic life. There have been many efforts to address this issue by holistic socio-cognitive variables but they do not seem explanatory enough in context-specific areas. Therefore, we aimed to investigate the root causes of plagiarism in a specific context, i. e. Iranian universities, by offering a structural model to reveal the building blocks of this phenomenon. Setting the goal, we chose Corbin and Strauss’s (2008) Grounded Theory (GT) approach, avoiding its paradigmatic cliché that a theoretical model emerges only from data without any pre-assumption. The research population included faculty members, PhD candidates and master’s students selected from universities in Tehran, Iran. Open theoretical sampling and, then, discriminative sampling were used. Fifty-one interviews, two newspaper interviews, and three focus groups were conducted. The interviewees were accessed through universities’ library and information centers. Taken together, 56 interviews were transcribed and codified. Lincoln and Guba’s (2008) criteria were used to control the quality of the research process. “Indifference” to plagiarism is the central phenomenon and “cultural depositories” plus “governmental capitalism” were found to be the root factors. These two factors may lead to “Bureaucratic university” (Moodie 2006) as a context for the emergence of “research formalism”, “uncritical education” and “scholastic habitus”. All these factors, together with direct reflexive elements including bad exemplars, the irresponsibility of professors, immoral trade-off, unscientific evaluation, insignificant differentiation, and vindications, lead to “indifference”. One of the research’s implications is that plagiarism in Iran seems not to result from individual-psychological factors but from cultural, economic, legal and organizational factors. Another implication is that in the investigation of social or organizational problems we should take a look at the concept of normality. We explored the factors tending to make a problem a normal phenomenon. We also pinpointed the things making people indifferent to a problem, factors pushing abnormal phenomenon to the realm of normality, and elements constituting the origins of the current order of things which are mysteriously silenced and practically behaved.
Promoting Equal Access to Public Digital Cultural Services in China: Efforts and Challenges
Authors: Wanyan Dengdeng , Dai Yanqing
Published: September 2019

With the development of information technology and the advent of the digital era, the digitization of cultural heritage and the internet-based equal access to the digitized heritage have received worldwide attention. Taking China as a case study, this paper reviews its efforts and challenges to promote equal access to public digital cultural services (PDCS). It starts by introducing the efforts, including PDCS-related legislations, policies and standards issued by the government, and major government-initiated PDCS projects. They are followed by an analysis of its challenges, including deficiencies in government funding, internet penetration, broadband access rates in the Central and Western regions and rural areas, and the limited digital literacy, cultural knowledge, and income levels of certain population groups. This study concludes with the suggestion that promoting equal access to PDCS in less developed regions, rural areas, and vulnerable groups is still an important task in China, and the government needs to work with private sector partners to overcome the challenges.
Changes in Scholarly Reading in Finland Over a Decade: Influences of E-Journals and Social Media
Authors: Tenopir Carol , Late Elina , Talja Sanna , Christian Lisa
Published: September 2019

Nationwide surveys of researchers in Finland in 2007 and 2016 distributed with the assistance of FinELib, the Finnish national consortium, show that researchers use a growing range of sources to find and access scholarly articles and that some reading patterns are changing. The percentage of articles found by searching and browsing are decreasing, while researchers are using more social ways to locate articles. Research social networking sites are rated as important to their work. They read more on-screen, although still print some material out for final reading. Reading patterns for books are different, as researchers still rely more on printed books than e-books, in spite of an increase in e-book collections through their libraries. This study shows a continuous process of incremental change, enabled by changes in scholarly publishing, social networking, and library collection decisions. More changes can be expected, as researchers adopt systems and patterns that fit with their work patterns and make the finding, locating, and reading of scholarly materials easier. Libraries must both lead and adapt to these new reading patterns by providing links and access to a variety of journal services and by maintaining a balance of print and e-book collections.

Towards Computer Simulations of Virtue Ethics
Authors: Lasquety-Reyes Jeremiah A.
Published: September 2019

This article presents two approaches for computer simulations of virtue ethics in the context of agent-based modeling, a simple way and a complex way. The simple way represents virtues as numeric variables that are invoked in specific events or situations. This way can easily be implemented and included in social simulations. On the other hand, the complex way requires a PECS framework: physical, cognitive, emotional, and social components need to be implemented in agents. Virtue is the result of the interaction of these internal components rather than a single variable. I argue that the complex way using the PECS framework is more suitable for simulating virtue ethics theory because it can capture the internal struggle and conflict sometimes involved in the practice of virtue. To show how the complex way could function, I present a sample computer simulation for the cardinal virtue of temperance, the virtue that moderates physical desires such as food, drink, and sex. This computer simulation is programmed in Python and builds upon the well-known Sugarscape simulation.1
Indikatorensystem zur Förderung der Ergebnisqualität in der stationären Langzeitpflege
Authors: Kelleter Heidemarie
Published: September 2019

Durch eine Neuregelung in der Pflegeversicherung soll die Qualität in der stationären Langzeitpflege durch Indikatoren vergleichbar werden. Anhand der Umsetzung des webbasierten Lernkonzepts zur indikatorengestützen Qualitätsförderung (inQS) kann dieser Effekt der Vergleichbarkeit bereits aufgezeigt werden. Wirkungen sind dabei in der digitalisierten Einführung der Indikatoren, dem Umgang mit Routinedaten sowie der Interpretation von Qualitätskennzahlen ersichtlich.
Neue Konzeption für Qualitätsbeurteilungen und die öffentliche Qualitätsdarstellung in der Langzeitpflege

Qualitätsmanagement in der Gesundheitsförderung – Das Gute besser machen
Authors: Hillenbrand Ann-Katrin , Walentzak Bettina , Heyn Martin
Published: September 2019

Qualität bezieht sich darauf, wie Standards, Anforderungen und Kriterien, die zuvor definiert wurden, erfüllt werden. Qualität ist damit auch immer eine Frage der Perspektive, denn Kriterien können unterschiedlich gewichtet werden [Bayerisches Landesamt für Gesundheit und Lebensmittelsicherheit (LGL) Herausgeber. Qualität in Gesundheitsförderung und Prävention. Dokumentation der Workshopreihe 2017 mit Prof. Dr. Petra Kolip. Band 7 der Schriftenreihe des ZPG. 2018]. Der vorliegende Beitrag beleuchtet das Verständnis von Qualitätskriterien insbesondere aus Landeszentrumsperspektive – hier mit Bezug zum Aufgabenspektrum und zu den Tätigkeitsfeldern des Bayerischen Zentrums für Prävention und Gesundheitsförderung (ZPG).

Effect of surfactants on mass transfer coefficients in bubble column contactors: an interpretative critical review study
Authors: Nekoeian Sahand , Aghajani Masoud , Alavi Seyed Mehdi , Sotoudeh Fatemeh
Published: September 2019

Since surfactants have been recognized as the most frequently faced contaminants of bubble column-related processes over time, their impact on the mass transfer operation of these columns has become a demanding research interest for two recent decades. Despite the similarities expressing the overall negative and positive influence of these chemicals on mass transfer coefficients and specific interfacial area, respectively, the discrepancies and, sometimes, paradoxical results are still under debate in the literature. To make a more comprehensive recognition of the mentioned subject, the current paper has tried to pave the path by reviewing all the major methods utilized in related research works. Thereafter, an interpretative argumentative comparison of the main findings of relevant studies has also been proposed, enlightening some of the research gaps which can be the potential candidates for future studies.

Three chlorinated theinyl chalcone derivatives, namely (E)-1-(5-chlorothiophen-2-yl)-3-(4-(methylthio)phenyl)prop-2-en-1-one (I), (E)-1-(5-chlorothiophen-2-yl)-3-(4-(dimethylamino)phenyl)prop-2-en-1-one (II) and (E)-1-(5-chlorothiophen-2-yl)-3-(2,3-dihydrobenzofuran-5-yl)prop-2-en-1-one (III), were synthesized and their crystal structures were determined by single-crystal X-ray diffraction analysis. CompoundsI,IIandIIIcrystallize in the monoclinic space groupsP 21/c(centrosymmetric),P 21/n(centrosymmetric) andPc(non-centrosymmetric), respectively. In all three compounds, the molecules are in a relatively planar conformation and adopt atransconfiguration with respect to the C=C double bond. The crystal packings are stabilized by weak hydrogen-bonds, π · · · π, C–H · · · π and C–Cl · · · π interactions. The intermolecular contacts and lattice energies were further analyzed by Hirshfeld surface analysis. The third-order nonlinear optical properties of these chalcone derivatives were investigated using the single beam Z-scan technique with a 5 mW continuous wave diode laser operating at 635 nm, where compoundIshowed the highest potential for optical application with its exclusive nonlinear refractive index and nonlinear susceptibility.
