Calcite and vaterite biosynthesis by nitrate dissimilating bacteria in carbonatogenesis process under aerobic and anaerobic conditions
Authors: Eltarahony Marwa , Zaki Sahar , Kamal Ayman , Abd-El-Haleem Desouky
Published: December 2019

Abstract. This study deals with 16S rDNA identified bacteria, Lysinibacillus sphaericus (71A), Raoultella planticola (VIP), and Streptomyces pluricolorescens (EM4) capable of precipitating CaCO3 through a nitrate reduction aerobically and anaerobically. The produced CaCO3 crystals were analyzed using XRD, EDX, and SEM. The results showed that the carbonatogenic bacteria served as nucleation sites for CaCO3 precipitation with distinct variation in polymorph and morphology; reflecting strain-specific property. Notably, the amount of precipitated CaCO3 recorded 3.27 (aerobic), 1.55 (anaerobic), 4.15 (aerobic), 3.75 (aerobic) and 1.87 (anaerobic) g/100 mL of strains 71A, EM4 and VIP, respectively, for 240 h of incubation. The study of changes in media chemistry during carbonatogenesis process revealed positive correlation between bacterial growth, nitrate reductase activity, pH, EC, amount of deposited CaCO3 and NO3− consumption. Therefore, the applications of these bacterial strains, which employed for the first time in carbonatogenesis process, are promising in the environmental, biomedical and civil engineering fields.
Acidification-vulnerable carbonate system of the East Sea (Japan Sea)

Published: December 2019

Abstract. The East Sea (Japan Sea) has its own deep overturning circulation, but this operates over a much shorter timescale than that in the open ocean. This allows the East Sea to be used as a natural laboratory in which to investigate potential future changes in the oceanic system. Dissolved inorganic carbon (DIC) and total alkalinity (TA) were measured in 2014 and 2017 to investigate the characteristics and temporal variability of the carbonate system of the East Sea. When the East Sea was compared with a site in the South Atlantic that has similar apparent oxygen utilization (AOU) values, it was also found to have similar DIC content of the deep waters. However, the TA levels in the East Sea were much lower than those recorded in the South Atlantic. Consequently, the DIC / TA ratio of the deep waters of the East Sea was high and similar to that in the North Pacific, which leaves the deep waters of the East Sea vulnerable to acidification by CO2 input. High export production of organic matter, together with low rates of CaCO3 export, are responsible for this high DIC / TA ratio. In the Ulleung Basin, in the southwest of the East Sea, the DIC and AOU of the deep waters increased between 1999 and 2014. pH decrease of the deep waters and shoaling of the carbonate saturation horizons was faster than that recorded in the oceans. Both slowed deep-water ventilation, and the intrusion of anthropogenic CO2 contributed to the acidification of the East Sea. However, a clear increase in DIC from the Japan Basin to the Ulleung Basin, accompanied by a commensurate increase in AOU, was observed in 2014, whereas the meridional gradient was absent in 1999. This observation appears to reflect recent changes in deep-water ventilation, such as the re-initiation of deep-water formation. The East Sea is extremely vulnerable to acidification and should be seen as a special case of ocean acidification rather than an example of how the oceans will respond to a slowdown in ventilation in the future.
Pattern and structure of microtopography implies autogenic origins in forested wetlands
Authors: Diamond Jacob S. , McLaughlin Daniel L. , Slesak Robert A. , Stovall Atticus
Published: December 2019

Abstract. Wetland microtopography is a visually striking feature, but also critically
influences biogeochemical processes at both the scale of its observation
(10−2–102 m2) and at aggregate scales (102–104 m2). However, relatively little is known about how wetland microtopography develops or the factors influencing its structure and
pattern. Growing research across different ecosystems suggests that reinforcing processes may be common between plants and their environment,
resulting in self-organized patch features, like hummocks. Here, we used
landscape ecology metrics and diagnostics to evaluate the plausibility of
plant–environment feedback mechanisms in the maintenance of wetland
microtopography. We used terrestrial laser scanning (TLS) to quantify the
sizing and spatial distribution of hummocks in 10 black ash (Fraxinus nigra Marshall) wetlands in northern Minnesota, USA. We observed clear elevation bimodality in our wettest sites, indicating microsite divergence into two states: elevated hummocks and low elevation hollows. We coupled the TLS dataset to a 3-year water level record and soil-depth measurements, and showed that hummock height (mean = 0.31±0.06 m) variability is
largely predicted by mean water level depth (R2=0.8 at the site scale, R2=0.12–0.56 at the hummock scale), with little influence of subsurface microtopography on surface microtopography. Hummocks at wetter sites exhibited regular spatial patterning (i.e., regular spacing of ca. 1.5 m,
25 %–30 % further apart than expected by chance) in contrast to the
more random spatial arrangements of hummocks at drier sites. Hummock size
distributions (perimeters, areas, and volumes) were lognormal, with a
characteristic patch area of approximately 1 m2 across sites. Hummocks
increase the effective soil surface area for redox gradients and exchange
interfaces in black ash wetlands by up to 32 %, and influence surface
water dynamics through modulation of specific yield by up to 30 %. Taken
together, the data support the hypothesis that vegetation develops and
maintains hummocks in response to anaerobic stresses from saturated soils,
with a potential for a microtopographic signature of life.
On fluctuating momentum exchange in idealised models of air–sea interaction
Authors: Wirth Achim
Published: December 2019

Abstract. The dynamics of three local models, for momentum transfer at the air–sea interface, is compared.
The models differ by whether or not the ocean velocity is included in the shear calculation applied to the ocean and the atmosphere.
All three cases are employed in climate or ocean simulations.
Analytic calculations for the models with deterministic and random forcing (white and coloured) are presented.
The short-term behaviour is similar in all models, with only small quantitative differences,
while the long-term behaviour differs qualitatively between the models.
The fluctuation–dissipation relation, which connects the fast atmospheric motion to the slow oceanic dynamics, is established for all models with random forcing.
The fluctuation–dissipation theorem, which compares the response to an external forcing to internal fluctuations,
is established for a white-noise forcing and a coloured forcing when the phase space is augmented by the forcing variable.
Using results from numerical integrations of stochastic differential equations, we show that the fluctuation theorem,
which compares the probability of positive to negative fluxes of the same magnitude, averaged over time intervals of varying lengths,
holds for the energy gained by the ocean from the atmosphere.
Bayesian full-waveform inversion of tube waves to estimate fracture aperture and compliance
Authors: Hunziker Jürg , Greenwood Andrew , Minato Shohei , Barbosa Nicolas D. , Caspari Eva , Holliger Klaus
Published: December 2019

Abstract. The hydraulic and mechanical characterization of fractures is crucial for a wide range of pertinent applications, such as, for example, geothermal energy production, hydrocarbon exploration, CO2-sequestration, and nuclear waste disposal. Direct hydraulic and mechanical testing of individual fractures along boreholes does, however, tend to be slow and cumbersome. To alleviate this problem, we propose to estimate the effective hydraulic aperture and the mechanical compliance of isolated fractures intersecting a borehole through a Bayesian Markov chain Monte Carlo (MCMC) inversion of full-waveform tube-wave data recorded in a vertical seismic profiling (VSP) setting. The solution of the corresponding forward problem is based on a recently developed semi-analytical solution. This inversion approach has been tested for and verified on a wide range of synthetic scenarios. Here, we present the results of its application to observed hydrophone VSP data acquired along a borehole in the underground Grimsel Test Site in the Central Swiss Alps. While the results are consistent with the corresponding evidence from televiewer data and exemplarily illustrate the advantages of using a computationally expensive stochastic, instead of a deterministic, inversion approach, they also reveal the inherent limitation of the underlying semi-analytical forward solver.
Massive simplification of the wind farm layout optimization problem
Authors: Stanley Andrew P. J. , Ning Andrew
Published: December 2019

Abstract. The wind farm layout optimization problem is notoriously difficult to solve because of the large number of design variables and extreme multimodality of the design space.
Because of the multimodality of the space and the often discontinuous models used in wind farm modeling, the wind industry is heavily dependent on gradient-free techniques for wind farm layout optimization.
Unfortunately, the computational expense required with these methods scales poorly with increasing numbers of variables. Thus, many companies and researchers have been limited in the size of wind farms they can optimize.
To solve these issues, we present the boundary-grid parameterization. This parameterization uses only five variables to define the layout of a wind farm with any number of turbines. For a 100-turbine wind farm, we show that optimizing the five variables of the boundary-grid method produces wind farms that perform just as well as farms where the location of each turbine is optimized individually, which requires 200 design variables. Our presented method facilitates the study and both gradient-free and gradient-based optimization of large wind farms, something that has traditionally been less scalable with increasing numbers of design variables.
Promoting Pro-Social Skills to Reduce Violence Among Urban Middle School Youth
Authors: Risisky Deb , MacGregor James , Smith Deborah , Abraham Jamie , Archambault MaryJo
Published: December 2019

Adolescent violence is a significant public health problem. The goal of this evaluation was to determine whether communication skills, relationships with adults, and relationships with peers were enhanced through participating in an after-school program aimed at reducing violence-related behaviors among urban middle school youth. Elements that helped to foster success among our population were providing a program that enabled consistent choice in recreational activities in a safe place, and also providing busing home to increase safety. A non-experimental study was conducted with 115 students who participated in the program. Bivariate, ANOVA analysis, and Kruskal–Wallis tests were carried out. Results indicated that participating in the program significantly impacted student relationships with adults and their peers as well as positively impacted their communication skills. The program was designed with purposeful activities that would address pro-social behaviors, enhance youth interest, and increase attendance. The program specifically used recreation to help foster relationships with their peers and the adults in the program, with the intention of reducing conflict, and therefore violence among the students.
Youth Developmental Experiences Among Female Hockey Players: The Role of Relative Age
Authors: Chittle Laura , Dixon Jess C. , Horton Sean
Published: December 2019

Relative age differences can lead to varying sport participation opportunities; however, scant research has focused on the impact of relative age on experiences within sport. This study explored if youth developmental experiences differed by relative age among competitive female ice hockey players. Players within Ontario (n = 264) completed an online survey that contained the Youth Experience Survey for Sport (YES-S) along with additional demographic questions. The YES-S measures 5 dimensions of positive (i.e., personal and social skills, cognitive skills, goal setting, and initiative) and negative developmental experiences in sport. The results of the multivariate analysis of variance (MANOVA) suggested that the developmental experiences reported by athletes did not differ across birth quartiles (Wilks’ Lambda = 0.940, F (15, 707.105) = 1.061, p = .390). Although there was a relative age effect (RAE) trend within this sample of competitive female ice hockey players, the differences across birth quartiles were not statistically significant. It appears that relative age does not result in youth having different positive and negative sporting experiences. Exploring the characteristics of sport environments (e.g., coaches, practices) and personality traits of competitive athletes to better understand how relatively younger athletes continue their participation in sport despite being at a perceived disadvantage warrants further investigation.

Relationship Between Flexible Working Arrangements and Job Satisfaction Mediated by Work-Life Balance: Evidence From Public Sector Universities’ Employees of Pakistan
Authors: Aziz-Ur-Rehman Maha , Siddiqui Danish Ahmed
Published: December 2019

The research focused on relationship between flexible working arrangements, work-life balance and job satisfaction in Karachi’s public universities. To investigate the null hypothesis that there is no relationship between these variables. Research design is descriptive as we determine the association between dependent and independent variables. Independent variable is flexible working arrangements which include: flexi-time, contractual working, work shifts and telecommuting, that are provided to employees to improve their productivity and maintain work-life balance. A structured questionnaire is designed to collect approximately 200-sample size via online and by university visits. Survey forms were distributed using random sampling method among more than nine different public universities of Karachi. The research is quantitative in nature and analyzed through CFA and SEM, using smart PLS. Findings show that flexible arrangements are significantly correlated with work-life balance. It also revealed that work-life balance is a strong mediator between flexible arrangements and job satisfaction. Importance of flexible arrangements within an organization is highlighted in the recommendations to improve employees’ satisfaction, their performance, work to family enrichment hence to increase productivity. Research included both quantitative and qualitative data and examined the relationship of ﬂexible arrangements, work-life balance and job satisfaction from the view point of public universities.
Socio-Cultural Adjustment and Job Performance Among Expatriates: A Critical Overview
Authors: Uddin Sayed , Hussin Rosazman , Ab Rahman Badariah
Published: December 2019

The significant aspect of the migration process is the adjustment to the socio-cultural as well as work conditions of the host country. Expatriates’ by and large, come from quite different socio-cultural backgrounds and different work conditions. They are acquainted with different norms and used to different work ethics which have shaped their performance and relations with persons at work. They have to work in a new situation with new personnel and have to adjust to the entire new socio-cultural and working scenarios. It is interesting yet a problematic phenomenon to study their social life, their adjustment to the new socio-cultural milieu, work environment and adoption to innovation in professional arenas. Thus, if the expatriates in one hand can adjust to the situation, they may perform their job well and complete their assignment; otherwise, their stay in the host country will adversely be affected. Thus, socio-cultural adjustment along with innovation adoption is an important phenomenon that affects expatriates’ stay in the host country, their performance at work and relation with co-workers. The research will carry out using the secondary sources; an overview of existing literatures. It will help to rectify the factors associated to suitable candidates for the organizations/institutions to hire the competent and multiskilled expatriates to host country.
Sacrifices, Sidekicks, and Scapegoats: Black Characters and White Stories in Nora Roberts’s Romances
Authors: Ali Kecia
Published: December 2019

In several of the scores of romance novels she published between the 1980s and the early 2000s, bestselling American author Nora Roberts limns whiteness by deploying black characters as sacrifices or sidekicks. In her recent novels (2016-19), villainous white characters who express racist sentiments become scapegoats, obscuring racism’s broader structural and cultural dimensions. At a time when discrimination within romance publishing and award-giving has gained attention, it is vital to explore how the genre continues to center white readers and white identities, even while explicitly condemning racism.
New Insights into the Evolution and Age of the Neoproterozoic Jebel Ohier Porphyry Copper Deposit, Red Sea Hills, Northeastern Sudan

Published: December 2019

New SHRIMP U-Pb data from dioritic to granodioritic synmineral intrusions associated with the Jebel Ohier porphyry copper deposit (mineral inventory, including NI43-101-compliant total inferred and indicated resources, of 593 million tonnes [Mt] at 0.33% Cu and 0.05 ppm Au, for 1.953 Mt of contained Cu and 933,600 oz of Au at 0.15% Cu cutoff) in the Red Sea Hills of northeastern Sudan have bracketed the age of mineralization to ca. 816 to 812 Ma. This age range, as well as constraints from new and existing lithogeochemical data, is consistent with the deposit’s formation from a productive parental magma source during the early stages in the evolution of an intra-Mozambique Ocean island arc. The Jebel Ohier porphyry copper deposit bears many similarities to well-documented Phanerozoic analogues elsewhere in terms of (1) the mapped style and zonation of hydrothermal alteration (i.e., proximal K-silicate–dominated, to sericitic, to distal propylitic alteration), (2) the occurrence of intense Cu-bearing A- and B-type vein stockwork, as well as sulfide-only C-type veins, anhydrite veins, and younger, peripheral D-type veins, and (3) the geochemical fingerprint of the associated porphyry, which is akin to those of ore-related Tertiary porphyries in the Escondida area in northern Chile. The multiphase intrusion hosting the Jebel Ohier porphyry copper deposit has been intruded by several generations of mafic to felsic postmineralization dikes and voluminous plutons, with a peak in magmatic activity coinciding with the suturing of the Gebeit terrane at ca. 724 Ma. In spite of, or perhaps because of, the occurrence of extensive postmineralization magmatism, and regardless of subsequent deformation, regional metamorphism, uplift, and erosion, the deposit has remained remarkably intact. The discovery of a relatively ancient, yet well-preserved porphyry copper deposit in the Neoproterozoic Arabian-Nubian Shield has major implications for the exploration potential of this resource-rich geologic terrain.

Published: December 2019

This study aims at examining the impact of infrastructure advancement of Southern Cross Lane (JLS) in Malang, Indonesia toward households’ economic activities. Furthermore, this study intended to understand the presence of new road infrastructure and tourism sectors toward households’ economic activities. This research applied a descriptive study by conducting focus group discussions with stakeholders and the local community in Malang, Indonesia. In addition, semi-structured questionnaires were implemented to obtain a better understanding of the existing phenomenon. The findings of the study showed that in the short term, the presence of a new road in Southern Cross Lane changes the economic activities of the household while in the long term, it provides various opportunities to be developed such as tourism sectors, hotels, and restaurants. However, the development efforts from each region depend on the plan of the local community. Furthermore, the existence of a new road in Southern Cross Lane contributes to greater access between cities in the south of East Java in Indonesia.
Understanding Financial Inclusion in Vietnam
Authors: Son Tran Hung , Liem Nguyen Thanh , Ly Huynh Thi Ngoc
Published: December 2019

The objective of this paper is to analyze the factors that affect the financial inclusion in Vietnam using the World Bank's Global Findex dataset. Analytical results show that income affects the use of official accounts and official savings. Education is positively correlated with official accounts and official savings, but is negatively correlated with the use of formal credit. Age influences official savings and the use of formal credit and this relationship is nonlinear. Sex does not impact the use of official and official savings accounts. However, being a woman tends to use formal financial channels more. The reason for not owning official accounts of individuals in Vietnam is mainly subjective (related to personal income). Being a woman and being older are less likely to use informal credit, while the lowest income-group people tend to use informal credit. From the results of this research, some policy implications are outlined to promote financial inclusion in Vietnam.

Published: December 2019

The purpose of this study is to examine and to explore the influence of website navigational design as a part of ICT, on decision to choose off road adventure service provider, as a sport tourism provider. The sample is 125 companies from varieties of type and category, by using purposive sampling. Data collected through literature review, observation and questionnaires. Path analysis is used as a data analysis technique with SPSS 20. Results shows that only search options influenced decision to choose off road adventure service provider. The other three dimensions don’t have influence in decision to choose off road adventure service provider. It shows that majority of people use website only to find information and tend to see navigation bar, individual hyperlink and image maps as not important. This means that the level of website literacy among consumer is still low. It is important for companies to educate their consumers on how website could benefit them.
Governance Innovation and Enhancement: The New One-Tier Model of UBI Banca
Authors: Magli Francesca , Nobolo Alberto
Published: December 2019

On the basis of their experience and capitalism model, every country has developed different systems of corporate governance. For many years, in various European countries, there were debates on the opportunities and methods of harmonising European company law; in Italy, one of the most important change was the possibility for limited companies to choose between three management and supervision models: the Italian traditional model, the two-tier model (of German origin), and the one-tier model (of Anglo-Saxon origin). In our study we analyse one-tier and two-tier systems, first theoretically and legislatively and theirs application in Italian quoted companies in the banking sector. We selected this sector because limited banking companies were created in Italy in a recently period (2006-2007), as a result of national amalgamation and merger operation. We illustrate an important case in depth, namely the governance system at UBI Banca as a phenomenological case. Main study’s objective is to analyse transition of UBI Banca from the two-tier model (2007) to the one-tier model (2018), identifying the main causes and reasons for this choice.
The Perceptions of Foreign Language Pre-Service Teachers Towards Multicultural Education: Case of the Faculty of Education, TIU-Erbil, Iraq
Authors: Celik Bunyamin
Published: December 2019

This study was conducted to investigate the perceptions of pre-service teachers majoring in English at the department of English Language Teaching (ELT)—Tishk International University Education Faculty in Iraq at the level of knowledge and attitude. Studies related to the concept of multiculturalism are significant as being discussed recently in our globalized world and Mesopotamia in Iraq. The present study was planned in 2018–2019 academic year by using case study design within the framework of qualitative research method. The study was carried out with 90 final year students (48 females and 42 males). The subject participated in the study on a voluntary basis. The data of the study were obtained by using semi-structured interview technique. The data obtained from the study was collected under certain codes and themes by content analysis. As a result of the analysis of the data, it was determined that pre-service teachers had both right and wrong learning about the concepts of multiculturalism and multicultural education, and their attitude levels were both positive and negative. In this regard, it is thought that it may be beneficial for prospective teachers to receive a training in the vocational education process related to multiculturalism and multicultural education. Conducting the studies to be planned for multicultural education applications by revealing different variables will enable the subject to be evaluated from different perspectives and will be beneficial for the enrichment of the literature on the subject.
Tweaking Harassment Through Tweets: A Critical Discourse Study of #MeToo
Authors: Akhtar Amir , Liu Kanglong , Jabeen Tahira , Afzaal Muhammad
Published: December 2019

The study aims to conduct an analysis of the discourse on #MeToo which the study takes to be the unmediated voice of the victims of sexual harassment to determine the ideology imbibed in the discourse. Teun A. van Dijk’s Ideology and discourse: A multidisciplinary introduction (2000) serves as the theoretical basis for the study as it attempts to categorize what constitutes harassment for the victims by looking at 3000 tweets posted over thirty days. The critical analysis of the data reveals that one of the most lacking elements in the life of the victims of sexual harassment is an acknowledgment of harassment as harassment. Most of the victims are abused, shamed and silenced when they try to share their panic experiences of life. The study shows that sexual harassment is a widespread social epidemic and can occur to a person of any age group, at any place and in any type of relationship. The study is significant as it presents the unmediated view of the victims of sexual harassment and compares it with the existing view of harassment. The significance of the study also lies in the fact that it analyzes the features of Twitter to determine their role in shaping the discourse. Previous studies on harassment talk about the issue or explore its features and types through various angles, but none of them focuses on the voice of the victims themselves.
Hidden Curriculum in Schools: A Comparison of Religious Otherness in Pakistani ELT Textbooks
Authors: Waqar Sajid , Burki Anita Bilal , Jahan Musarrat
Published: December 2019

The emphasis of this research was religious otherness depiction in high school English textbooks issued by four State controlled Pakistani textbook boards of i.e., BTB Quetta, STB Jamshoro, KTB Peshawar and PTB Lahore. It besets a broad contrast among the religious otherness descriptions as depicted in provincial ELT textbooks and the otherness related notions of their corresponding students. To achieve the goals, the study was alienated in 2 phases: In phase 1, the textbooks of government textbook publishing boards were investigated and in the second phase their corresponding readers’ religious otherness ideas were obtained and evaluated. The research devised a modified model of analysis by blending Van Dijk (1998) and Fairclough (2001) CDA model for interpretation and explanation of religious otherness in representative text extracted from textbooks’ discourse. The study discovered the prevalence of religious otherness- related themes in all ELT textbooks. It was also found that STB discourse had improved religious otherness images and students’ otherness ideas than other provincial textbook boards and their respective readers. The study also revealed that Muslim male and female students had peculiar otherness notions about minority religious communities. The readers’ responses to questionnaire items in phase 2 of research suggested that textbooks had a significant part in molding otherness related notions of young readers. The study recommended an otherness-based investigation of the textbooks prior to publication at federal government level to ensure citizenship equality as envisioned by founder of the nation.
Optimization of Micro-Electrical Discharge Machining Parameters of Ti6AL4V Component: A Mapping Study
Authors: Apostolopoulou Christina , Al-Juboori Laith Abdullah
Published: December 2019

The micro-Electrical Discharge Machining (micro-EDM) is a non-conventional machining process which utilizes electro-thermal, non-contact effects to remove material from the workpiece. Micro-EDM is controlled by many machining parameters and its accuracy is evaluated by performance measures. It is employed when high accuracy and precision are required, especially when difficult-to-machine materials, like titanium alloy Ti6Al4V, are involved. Given the tremendous applications of Ti6Al4V in biomedical devices, automotive, aerospace and microelectromechanical systems, it is valuable to examine thoroughly the micro-EDM of Ti6Al4V component. This work reports a systematic mapping study of 36 papers published in journals and proceedings of conferences in the nearly two decades 2000-2018. First, we divide the papers into categories according to the various optimization techniques applied for the enhancement of micro-EDM machining process of Ti6Al4V component. Then, we discuss the techniques most used and give insight into the current research trends in micro-EDM. Accompanying comments about the use of the mentioned studies for teaching purposes may be of considerable interest for educators.
Landmilitärische oder seemilitärische Expertise? Transformationen der Legitimationsbasis der Kaiserlichen Marine, ca. 1871–1900 / Expertise by Land or Sea? Changing Patterns of Legitimation of the German Navy, c. 1871–1900
Authors: Rojek Sebastian
Published: December 2019

Unmittelbar vor dem Ersten Weltkrieg hatte die deutsche Marine eine enorme politische und kulturelle Bedeutung. Ihre von souveränen Experten gebauten Kriegsschiffe galten als hochmoderne Spitzentechnik, die die nationale Leistungsfähigkeit symbolisierten und einen weltpolitischen Aufstieg Deutschlands zu verbürgen schienen. Wie hatten die Seestreitkräfte eine solch starke Stellung erlangt? Diese Frage drängt sich umso mehr auf, bedenkt man, dass die Marine in den frühen 1870er Jahren als recht unbedeutend galt und weit hinter der Armee zurückblieb, ja tatsächlich unter der Kontrolle von Generälen stand. Der Aufsatz verfolgt, wie der rasche technische Wandel im Schiffbau dazu führte, dass im Zuge der öffentlichen Verhandlungen um ein schweres Schiffsunglück die neue normative Erwartung entstand, dass die Marine von seemilitärischen Experten geführt werden müsse. Obwohl die Seestreitkräfte noch längere Zeit von Armeegenerälen geleitet wurden, begann doch eine schrittweise Wahrnehmungsveränderung, die die Institution schließlich aus dem Schatten der Armee führte. In dem Maße, in dem es den Akteuren der Marine gelang, sich erfolgreich als Experten zu inszenieren und legitimieren, vergrößerte sich auch ihr politischer Handlungsspielraum. Der Bedeutungszuwachs der Marine ergab sich also nicht von selbst, sondern erst, als der technische Wandel in Bezug auf die seemilitärische Expertise der Leitung der Flotte öffentlich verhandelt wurde. Im Sinne einer Kulturgeschichte der Technik geht der Beitrag also am Beispiel der Seestreitkräfte der Frage nach, wie über die politische Bedeutung technischer Herausforderungen gesellschaftlich kommuniziert wurde.
Von der Rechtsgemeinschaft zur Verweigerungsunion?
Authors: Wunderlich Nina
Published: December 2019

Der vorliegende Aufsatz widmet sich der Frage, ob sich die Europäische Rechtsgemeinschaft aufgrund einer etwaigen Verweigerungshaltung der EU-Mitgliedstaaten in einer Krise befindet, wie kritische Stimmen es zum Teil nahe legen. Anhand einer allgemeinen Bestandsaufnahme zu den Vertragsverletzungsverfahren, die die Europäische Kommission in den letzten Jahren eingeleitet hat, sowie einer Betrachtung mitgliedstaatlichen Handelns im Rahmen der Finanz- und Wirtschaftskrise sowie der Migrationskrise, nähert sich der Beitrag der Frage, ob sich die Mitgliedstaaten im Grundsatz rechtstreu verhalten. Gegenstand der Untersuchung ist dabei auch, ob Verstöße gegen das in Art. 2 EUV verankerte Rechtsstaatsprinzip durch Vertragsverletzungsverfahren - ggf. neben Verfahren nach Art. 7 EUV - geahndet werden können.
Neues zum einstufigen Vertragsverletzungsverfahren gem. Art. 260 Abs. 3 AEUV – zugleich Anmerkung zum Urteil des EuGH v. 8.7.2019, Rs. C-543/17 (Kommission/Belgien)
Authors: Wendenburg Albrecht
Published: December 2019

Der EuGH (Große Kammer) hat am 8.7.2019 sein erstes Urteil zum einstufigen Vertragsverletzungsverfahren gem. Art. 260 Abs. 3 AEUV verkündet. Dieses Verfahren wurde erst 2009 mit dem Vertrag von Lissabon in das Unionsrecht eingefügt. Mit dem Urteil klärt der EuGH eine Reihe zuvor umstrittener Rechtsfragen. Die Konsequenzen für die Mitgliedstaaten dürften beträchtlich sein: Sie werden ihre Anstrengungen bei der fristgerechten und vollständigen Richtlinienumsetzung verstärken müssen, um künftig Sanktionen zu vermeiden. Diese Herausforderung gilt für föderal organisierte Mitgliedstaaten wie Deutschland in besonderem Maße. Nur „artikelscharfe“, das gesamte Territorium des Mitgliedstaats umfassende Mitteilungen über die erfolgte Richtlinienumsetzung können Sanktionen künftig sicher verhindern.

Published: December 2019

This contribution examines the process of appointing the President of the European Commission in the aftermath of the European elections 2019. It analyses the interests of the players involved and mirrors these against the backdrop of patterns of earlier nominations. In addition, the article reflects on consequences for the political system of the European Union as a whole, especially with regard to the role of European political parties. The contribution finally develops possible scenarios for future appointments: In general, these could take cooperative or competing formats. In case of furthering supranational elements transnational lists could be used in combination with the “Spitzenkandidaten process”. This would still require a “saut qualitatif” by the European party families.

El Libro de los Juramentos del Ayuntamiento de Toledo es considerado uno de los códices más importantes custodiados en el Archivo Municipal de la ciudad, si bien, aunque los estudios referentes a su contenido se han tenido en cuenta desde hace décadas, no ha sido el caso en lo referente a su aportación artística. Los folios iluminados y enmarcados con bellas orlas han fascinado a todos los que, por alguna razón, se acercaron al manuscrito toledano, por lo que nuestro principal objetivo ha sido analizar desde el punto de vista estético, estilístico e iconográfico el conjunto de repertorios iluminados.En el proceso de estudio ha sido fundamental el análisis comparativo con otros códices que hemos considerado contemporáneos, pues en base a la fecha de renovación del volumen manuscrito, la diligencia del último folio apunta al año de 1594. De igual manera hemos podido concluir una importante conexión estilística y técnica con las nuevas fórmulas de iluminación, iniciadas en el scriptorium del monasterio de El Escorial desde el último cuarto del quinientos.AbstractThe Book of Vows of the City Hall of Toledo is considered one of the most important codex kept in the Archive of the city. The studies regarding its content have been already analyzed for decades, but its artistic contribution has been neglected. The illuminated pages, beautifully framed, have fascinated all those who have approached the Toledo manuscript. Our main objective has been to analyze from the aesthetic, stylistic and iconographic point of view the set of illuminated repertoires.This article will stablish new relations with other codices that we have considered contemporary, according to the date of renewal of the book: the year 1594. We have been able to link this work stylistically and technically with the new formulas of illumination, started at the scriptorium of the monastery of El Escorial during the last quarter of the five hundred.

Este estudo objetivou analisar como os estudantes estabelecem suas decisões para a escolha de uma instituição de Ensino Superior, na perspectiva de alunos em curso do terceiro ano do Ensino Médio. Foram entrevistados 26 estudantes, a partir de um roteiro previamente elaborado, contendo as seguintes dimensões: grupos de referência, marca, programas de incentivo do governo, infraestrutura e preço. Os grupos de referência se mostraram a principal influência recebida dos estudantes na escolha da IES, sendo que parece haver um consenso sobre a formação da percepção à cerca da marca, a partir de compartilhamento de experiências com parentes e amigos próximos. Ainda, o artigo abre espaço para o questionamento à cerca do que seria a qualidade de ensino para os estudantes, considerando-se a intangibilidade do serviço e a dificuldade para o público discente avaliar aspectos pertinentes ao que seria uma estrutura que oferta serviços de qualidade. Destaca-se, como implicação gerencial, a importância de as IES formarem uma identidade da marca, que pode ser reconhecida por toda a comunidade de interesse.

O curso de Ciências Contábeis no Brasil vem ganhando cada vez mais espaço por diversos fatores. Assim, alinhar as expectativas desses estudantes com as necessidades do mercado de trabalho é fundamental para o sucesso dessas instituições. Esta pesquisa busca investigar as expectativas dos alunos de Ciências Contábeis de um Centro Universitário no litoral norte do Rio Grande do Sul sobre o mercado de trabalho, avaliando suas pretensões para a área de atuação após a graduação. Para isso, foi realizado um estudo quantitativo e descritivo, com utilização de questionário aplicado aos estudantes do referido curso da Instituição de Ensino, com perguntas fechadas sobre as características pessoais e áreas que desejavam atuar no início do curso e atualmente. As respostas obtidas foram colocadas no programa estatístico SPSS (Statistical Package for the Social Sciences), a fim de usar a ferramenta Tabelas de Referência Cruzada e analisar se as características pessoais afetam na escolha da área de atuação. Foram obtidos como resultados que gênero, idade ou semestre não afetam na escolha da área de atuação e que a Contabilidade Pública e Contabilidade Geral foram as áreas mais escolhidas entre os entrevistados, além de que no início do curso os alunos pouco conhecem sobre as áreas de atuação da contabilidade.

Vivemos numa sociedade que tem sua base de funcionamento e sobrevivência na mobilidade, na possibilidade de movimentação, no direito de ir e vir, de enviar e receber. Sendo assim, o objetivo deste artigo é analisar os impactos ambientais dos quatro veículos mais vendidos em 2018. Para isso, utilizou-se a metodologia de dinâmica de sistemas através da aplicação de modelagem e simulação computacional. A partir da elaboração de um modelo, construíram-se cenários de cada veículo que foram avaliados em um horizonte de dez anos, verificando, em cada situação, os impactos ambientais.

Este artigo traz uma parte dos resultados de uma pesquisa aplicada pelo Projeto Ideando, da Univille, a empresas participantes do ENIT - Feira e Encontro de Negócios, Inovação e Tecnologia, realizado em 2018, no munícipio de São Bento do Sul – SC. A abordagem quantitativa ofereceu dados sob a ótica de ambientes criativos, uso de ferramentas de gestão de ideias e a percepção sobre a relação entre gestão de ideias e inovação. Como resultado, destaca-se que a cultura organizacional e suas práticas de geração e gestão de ideias parecem carecer de estruturação e que a cultura da inovação ainda é fator estratégico a ser melhor compreendido pelas empresas da região, necessitando portanto de pesquisas mais aprofundados e abrangentes.
Practical Guide to the Design, Fabrication, and Calibration of NIST
Nanocalorimeters
Authors: Yi Feng , Grapes Michael D. , LaVan David A.
Published: December 2019

We report here on the design, fabrication, and calibration of nanocalorimeter
sensors used in the National Institute of Standards and Technology (NIST)
Nanocalorimetry Measurements Project. These small-scale thermal analysis instruments
are produced using silicon microfabrication approaches. A single platinum line
serves as both the heater and temperature sensor, and it is made from a 500 μm wide,
100 nm thick platinum trace, suspended on a 100 nm thick silicon nitride membrane
for thermal isolation. Supplemental materials to this article (available online)
include drawing files and LabVIEW code used in the fabrication and calibration
process.
Panta rhei? Space of flows in the era of anthropocene and outlooks into a multi-coloured future
Authors: Meier-Dallach Hans-Peter , Heinickel Gunter
Published: December 2019

The modern social, economic and communication flows change profoundly the development of spaces, their borders and boundaries, and affect the channels of flow between regions and the national, transnational and global society. The paper offers a reflection about the developments at the top of geographic and social scientific research as well as a reference to the agenda of spatial planning and politics. Therefore this article focuses on theoretical aspects of the “fluid society” but emphasizes also the need to learn from empirical insights and practical issues in the context of Polish-Swiss cooperation projects. It concludes however, that regional spaces under the auspices of modern flows are not unicoloured. That wants to say: they are not passive entities of modernisation, but keep their manifold, multicoloured characteristics – and these characteristics interact in the form of identities, cohesion and the natural backdrop with significant effects on those flows, enabling and steering modernisation strategies, and deciding about successes or failures of investments into traffic, tourism and economies. By that they shape the flows from and into peripheral regions.
