Expectation Management in Mergers and Acquisitions
Authors: He Jie (Jack) , Liu Tingting , Netter Jeffry , Shu Tao
Published: November 2019

Takeover bidders in stock-for-stock mergers have strong incentives to increase their own premerger stock prices to lower their acquisition costs. We find that before announcements of stock mergers, bidders manage down analyst earnings forecasts prior to earnings releases. Such expectation management benefits bidders by increasing their own stock prices and saving on acquisition costs. Additionally, analysts who have close relations with stock bidders are more likely to participate in expectation management. For identification, we use an instrumental variable analysis, a pseudo-event analysis, and a propensity score-matching approach. Our paper provides evidence on expectation management as a previously underexplored opportunistic behavior by takeover bidders.

Caenidae (Caenis) is recorded from Goiás for the first time, as well as new records of 10 genera and 16 species. Key words: Cerrado; Checklist; Neotropics; Brazilian Savanna; mayfly; taxonomy
Extralimital Dynastinae (Coleoptera: Scarabaeidae) in Australia

Authors: ALLSOPP PETER GEOFFREY , HUTCHINSON PAUL
Published: November 2019

The identification, origin, introduction, establishment, spread and pest status of extralimital (introduced, those that naturally occur within and outside Australia, and possibly introduced but of uncertain origin) dynastines in Australia and its territories are reviewed. We examine likely introduction pathways and the species’ life histories and attempt to draw out factors that predispose some species to establish, naturalise and then become invasive. Six categories of extralimital dynastines are identified: established and have spread widely (invasive)—Cyclocephala signaticollis Burmeister, 1847, Heteronychus arator (Fabricius, 1775); established but have not spread widely (sleepers)—Oryctes rhinoceros (Linnaeus, 1758), Oryctoderus latitarsus Boisduval, 1835 (possibly), Papuana woodlarkiana (Montrouzier, 1855) (possibly), Temnorhynchus retusus (Fabricius, 1781); known from one or only a few specimens that have arrived but not established—H. parumpunctatus Burmeister, 1847, Or. centaurus Sternberg, 1910, Pa. angusta Arrow, 1914, Pentodon algerinus algerinus (Fuessly, 1778); with distributions that extend from New Guinea into northeastern Australia—Pa. woodlarkiana (possibly), Od. latitarsus (possibly), Xylotrupes carinulus Rowland, 2011; whose records within Australia are doubtful—Dipelicus integriceps (Fairmaire, 1877), D. montrouzieri (Reiche, 1860), Or. nasicornis (Linnaeus, 1758), Pa. tibialis Arrow, 1941, Phyllognathus degener Fairmaire, 1891; species whose identity is unclear—Carne’s (1981) enigmatic species. Characters that make a species an ideal tramp species are: adults feed and are active for an extended period after emergence; larval development is relatively quick; adults and larvae are associated with potted plants and lawn grasses; the native distribution is in the Southern Hemisphere so that life cycles are synchronised between original and introduced localities. Shipping ballast and potted plants were the probable major pathways of introduction, but now rapid air and land transport provide the means for movement into and within Australia of hitchhiker species. Key words: Dynastinae, introductions, exotic species, pest species, quarantine, biosecurity

Authors: Suryadi Ujang , Nugraheni Yudhi Ratna , Prasetyo Anang Febri , Awaludin Aan
Published: November 2019

Background and Aim: A local microorganism-based probiotic has been developed as an alternative to using antibiotic growth promoter and its effect on broiler meat quality has been studied, when supplemented with poultry feed at different concentrations. This study aimed to understand the effect of local microorganism-based probiotic sourced from cattle rumen and chicken intestine and added as feed supplement at different concentrations on broiler meat quality.

Materials and Methods: The local microorganism-based probiotic made from cattle rumen and chicken intestine contained Lactobacillus spp., Bifidobacterium spp., Streptococcus spp., and Bacillus spp. The experiments followed a completely randomized design. Treatments in the study were: P0, i.e., control (without probiotic), P1 (probiotic administered at 5 ml/kg feed), P2 (probiotic administered at 10 ml/kg feed), and P3 (probiotic administered at 15 ml/kg feed). Each treatment was repeated 5 times. Parameters examined in this study were pH, meat tenderness, fat content, and meat protein content.

Results: Based on a total of 200 chickens, the percentage of meat protein content in treatments P1, P2, and P3 showed an increase of 19.34%, 19.42%, and 19.64%, respectively, when compared with P0 that showed a protein content increase of 19.14%. The fat content of meat for P1, P2, and P3 was 21.54%, 21.46%, and 21.30%, respectively, which was less than the value for P0 (21.69%). The treatments did not significantly affect pH or meat tenderness when compared with the control. The usage of this novel probiotic as a feed supplement resulted in an increase in meat protein content and a decrease in fat content.

Conclusion: This study indicates that using the local microorganism-based probiotic sourced from cattle rumen and chicken intestine to supplement poultry feed did not have a significantly different effect (p>0.05) on meat pH; however, it had a significantly different (p<0.05) on protein and fat content of broiler meat.

Published: November 2019

Dada a necessidade de prover rodovias mais seguras aos usuários, este trabalho buscou identificar os impactos dos parâmetros geométricos na frequência e na severidade dos acidentes em curvas de rodovias de pista simples. Esta análise foi conduzida para 225 quilômetros de trechos rodoviários de pista simples da BR 116 no estado do Rio Grande do Sul. A reconstituição geométrica rodoviária viabilizou a construção de uma base de dados que reúne as características dos acidentes registrados entre 2007 e 2016 pela Polícia Rodoviária Federal (PRF) e os parâmetros geométricos, permitindo a modelagem da frequência e da severidade dos acidentes a partir desses parâmetros. Foram estimados os modelos econométricos: (i) binomial negativo (BN) para a modelagem da frequência; e (ii) logit ordenado (LO) para a severidade de acidentes. Os resultados indicam que o aumento da declividade e da superelevação impactam no aumento da frequência de acidentes e na redução da severidade.
Estimativa do volume de passageiros ao longo de uma linha de transporte público por ônibus a partir da geoestatística
Authors: Marques Samuel De França , Pitombo Cira Souza
Published: November 2019

A modelagem clássica da demanda por transportes ignora um importante aspecto normalmente presente na estrutura das variáveis de interesse: a autocorrelação espacial. Pesquisas recentes reconhecem e incluem tal característica à estimativa da demanda, mas há limitações referentes aos elementos básicos de tratamento utilizados nas abordagens. No intuito de superar alguns problemas e restrições associados aos estudos anteriores, o presente trabalho se valeu da dependência espacial entre as observações de Embarques e Desembarques, por ponto de parada, e Carregamento nos trechos, ao longo de uma linha de transporte público, a fim de gerar estimativas dessas variáveis em pontos e trechos que não seriam amostrados por ocasião da pesquisa sobe/desce. Tal previsão foi realizada por meio da aplicação de Krigagem Ordinária a uma linha de ônibus da cidade de São Paulo, Brasil. Os resultados obtidos confirmaram a adequabilidade do ferramental geoestatístico à estimativa de variáveis de demanda por transportes ao longo de uma linha de ônibus.

Validou-se essa relação em duas etapas: inicialmente, com base em um review das dimensões e indicadores de mobilidade urbana sustentável; depois, por meio de uma pesquisa de opinião de 26 especialistas trabalhada por três métodos: distribuição de pontos, ordenamento e discriminação de pesos por ranking. Validado, o rol revela seis grupos de importância, os dois mais relevantes compostos pelos elementos: prioridade e qualificação do transporte ativo e do transporte público; participação social permanente; e vinculação ao plano de desenvolvimento urbano.
TUNNEL PORTAL INSTABILITY IN LANDSLIDE AREA AND REMEDIAL SOLUTION: A CASE STUDY
Authors: Farhadi Ayoublou Farhad , Taromi Majid , Eftekhari Abbas
Published: November 2019

The construction of tunnel portals in mountainous or slope areas often involves problems, which are closely related to factors, such as slope topography, geology, geotechnics, construction geometry and the tunnel excavation method. The activation of landslides or the acceleration of these events is one of the main challenges faced in the construction of tunnel portals. In this paper, we address the instability problem in Sabzkuh tunnel portal that has been excavated with a complex geological profile and high seismicity in Iran’s High Zagros region. The complexity and intense heterogeneity in geological formations, land acquisition problems and the lack of appropriate monitoring programs led to the instability of the tunnel portal. The excavation process started without applying appropriate techniques for a ground stabilization. The use of inappropriate tunnel excavation methods for this unstable geological structure resulted in an activation of an old Solaghan fault and several collapses in the tunnel. Crossing the collapsed areas and reinforcing the tunnel portal took about 7 months and imposed heavy costs on the project. This case study deals with the importance of the choice of the site location, ground and underground monitoring, analysing and summarizing the collected data in order to prepare a geological model before and during the construction process.
AUTOMATIC RECONSTRUCTION OF ROOF MODELS FROM BUILDING OUTLINES AND AERIAL IMAGE DATA
Authors: Hron Vojtěch , Halounová Lena
Published: November 2019

The knowledge of roof shapes is essential for the creation of 3D building models. Many experts and researchers use 3D building models for specialized tasks, such as creating noise maps, estimating the solar potential of roof structures, and planning new wireless infrastructures. Our aim is to introduce a technique for automating the creation of topologically correct roof building models using outlines and aerial image data. In this study, we used building footprints and vertical aerial survey photographs. Aerial survey photographs enabled us to produce an orthophoto and a digital surface model of the analysed area. The developed technique made it possible to detect roof edges from the orthophoto and to categorize the edges using spatial relationships and height information derived from the digital surface model. This method allows buildings with complicated shapes to be decomposed into simple parts that can be processed separately. In our study, a roof type and model were determined for each building part and tested with multiple datasets with different levels of quality. Excellent results were achieved for simple and medium complex roofs. Results for very complex roofs were unsatisfactory. For such structures, we propose using multitemporal images because these can lead to significant improvements and a better roof edge detection. The method used in this study was shared with the Czech national mapping agency and could be used for the creation of new 3D modelling products in the near future.

Published: November 2019

Research in the field of underactuated systems shows that control algorithms which take the natural dynamics of the system’s underactuated part into account are more energy-efficient than those utilizing fully-actuated systems. The purpose of this paper to apply the two-degrees-of-freedom (feedforward/feedback) control structure to design a swing-up manoeuver that involves tracking the desired trajectories so as to achieve and maintain the unstable equilibrium position of the pendulum on the cart system. The desired trajectories are obtained by solving the boundary value problem of the internal system dynamics, while the optimal state-feedback controller ensures that the desired trajectory is tracked with minimal deviations. The proposed algorithm is verified on the simulation model of the available laboratory model actuated by a linear synchronous motor, and the resulting program implementation is used to enhance the custom Simulink library Inverted Pendula Modeling and Control, developed by the authors of this paper.

The paper presents a method of producing Circular Cross-Section Columns (CCSC), which can provide sufficiently precise dimensions, with longitudinal reinforcement securely fixed in special plugs. An investigation procedure for determining the capacity of CCSC at all the stages of their loading with eccentric pre-stressing has been presented. Based on the conducted experimental work, load carrying and deformation parameters of the strain-stress state of reinforced concrete CCSC have been obtained. The investigation results make it possible to define calculation prerequisites and fracture criteria of the deformation method of calculating compressed-bent elements of CCSC at transverse bending and reinforcement deformation below the yield point.

Planning in public domain in practice is seemingly seen as a utopian concept. Once the knowledge that becomes the basis of planning is built on the pure understandings to cope the problem objectively, in reality, it turns into inflexible and rigid approaches when dealing with various interests, namely political and social subjects. This is because of the distinct perspectives and understanding owned by people, the planning stakeholders which are divergent, and stirred by individual interest. What becomes an evident is that the plentiful of interest tends to trigger the opposite arguments. Accordingly, planning in public domain that hoped to have neutral position is like having a castle in the air, because the individual interests of the stakeholders of planning seems to be inseparable aspects. Planners are then required to have multi-skill of a wide range knowledge, indeed to find it like a search for demigods, albeit by involving many skill groups that ends on a new issue of integrating thinking. This article will therefore attempt to parse a possible problem resolution through the concept of consensus-building, by first explaining its relevance in the context of planning, complexity and commonly used methods, in order to achieve common goals of development, and thereby placing the planner and their plans becomes as a valuable works, its worhted.
Online Platforms and the Digital Turn in EU Contract Law: Unfair Practices, Transparency and the (pierced) Veil of Digital Immunity
Authors: Iamiceli Paola
Published: November 2019

The digital revolution has pervaded entire sectors of economy and society, creating new markets and new market intermediaries, able to aggregate massive demand and offer beyond any conceivable thresholds in the offline setting.

The article moves from the recent adoption of the EU/2019/1150 Regulation on fairness and transparency for business users of online intermediation services and the pending reform of several consumer directives under the auspices of the Digital Agenda and the New Deal for Consumers. It focuses on the role of online platforms and addresses two main policy issues: (i) whether EU legislation should go beyond the adaptation of existing rules opting for a sharper turn towards dedicated regulatory tools in the field of digital law, and (ii) whether the digital dimension of trade should lead to revise the current focus on consumer protection and, more broadly, the current divide between BtoC and BtoB law.

Digital private law is taking the first steps into the internal market. Whereas national private law will continue to provide the general framework for private law matters arising in the internet and may certainly contribute to define model rules for ad hoc legislation on digital trade, the EU legislation is due to play a major role and to find new balances between the fundamental freedoms and the protection of digital users. The digital challenge will enable EU institutions to take part in a global venture well beyond the boundaries of the internal market.
Larch-derived hierarchical nitrogen-doped carbon with echinus-like architecture for supercapacitor applications
Authors: Chen Honglei , Sha Lei , Zhang Yujie , Wang Shoujuan , Kong Fangong , Muench Falk , Zhao Xin
Published: November 2019

Echinus-like nitrogen-doped carbon with a hierarchical porous structure was synthesized from green larch waste and urea via liquid in situ doping and high-temperature carbonization. Benefitting from a large specific surface area (649 m2 g−1) and hierarchical porous structure, the nitrogen-doped carbon exhibited excellent electrochemical performance for supercapacitors. Remarkably, the echinus-like nitrogen-doped carbon achieved a high specific capacitance of 340 F g−1 at a current density of 1 A g−1 in 6 M KOH electrolyte as well as a good performance rate and stability (with a capacitance retention of 98% after 5000 cycles). This capacitance was almost 1.5 times higher than that of undoped carbon due to the contribution of the pseudocapacitance from the nitrogen doping. Larch sawdust is a promising carbon source for fabricating inexpensive, sustainable and high-performance supercapacitor materials.
Determination of the frequency of β-lactamase genes (bla SHV, bla TEM, bla CTX-M) and phylogenetic groups among ESBL-producing uropathogenic Escherichia coli isolated from outpatients

Published: November 2019

Background

Escherichia coli accounts for 70–95% of community-acquired urinary tract infections (UTIs). Recently, there has been an increase in the prevalence of extended-spectrum β-lactamase (ESBL) in the community which required an accurate identification for better management. Therefore, the current study was performed to determine the antimicrobial resistance pattern, investigate ESBL phenotypes and genotypes (blaCTX-M, bla TEM and bla SHV genes) and determine the phylogenetic groups among ESBL-positive isolates from outpatients.

Methods

One hundred and eighty-three positive urine samples were collected from 4450 outpatient clinic attendees. Antibiotic susceptibility was determined and ESBL phenotype screening was carried out using disk diffusion agar and combination disk techniques, respectively. The assessment of the presence of the blaCTX-M, bla TEM and blaSHV genes and phylogenetic grouping were performed using the polymerase chain reaction (PCR) method.

Results

Out of 183 E. coli isolates, 59 (32.2%) showed a positive ESBL phenotype. The prevalence of ESBL-producing E. coli was higher in males (57.4%). Fifty-seven of the ESBL-producing strains carried at least one of the β-lactamase genes (bla CTX-M, bla TEM, bla SHV). Phylotyping of multi-drug resistant isolates indicated that the isolates belonged to B2, A and D phylogroups. Analysis of resistance patterns among these phylogroups revealed that 74.4%, 55.3% and 29.7% of the isolates in the B2 group were resistant to trimethoprim-sulfamethoxazole, ciprofloxacin and gentamicin, respectively. Most of the strains in the phylogroup B2 carried the bla CTX-M gene.

Conclusions

All the ESBL-producing isolates were placed in one of the four phylogenetic groups. The presence of CTX-M and resistance to quinolones were more frequent in B2 strains than in non-B2 strains.

The Tool Noun and Tool Verb Alternation in Gesture
Authors: Wu Suwei
Published: November 2019

In recent years, increasing attention has been devoted to investigating what aspects of grammar in spoken language are coordinated with gesture. However, previous studies have focused on gesture use in relation to other grammatical categories rather than the basic grammatical categories of nouns and verbs. Against this background, this study, taking the tool noun and tool verb alternation as a starting point, considers to what extent gesture relates to the tool frame and to what extent it relates to the choice of nouns or verbs and accordingly the means of construal afforded by nouns and verbs. It is found that the number of gestures produced and the dominant gesture mode are largely dependent on the tool frame, but some other aspects in gesture do vary depending on the choice of nouns or verbs in speech, and these differences in gesture seem to correlate with the difference between how speakers conceptualize nouns and verbs, as hypothesized in the theory of cognitive grammar: nouns profile THINGS while verbs profile PROCESSES. This finding adds to previous studies about which aspects of grammar relate to gesture and how they do so, thereby furthering our understanding of the integrated nature of speech and gesture.
Using College Football as an Analogy in Teaching College Diversity Courses
Authors: Jones Adam C. , Krupitzer Kelsie , Watts Kiarra , McCrory Gary
Published: November 2019

Diversity can be a difficult subject to teach in higher education, especially in settings where exposure to diverse cultures can be limited The use of analogies or metaphor can be particularly useful to provide students with opportunities to think critically about new topics while relating the material to familiar subjects. In this article, we propose the use of an analogy of college football as a way to better integrate diversity topics into college classrooms. The broad appeal of college football on college campuses lends itself as a great platform to discuss otherwise challenging topics such as privilege, racism, sexism, sexuality, and power in the United States. The use of analogies can create a non-confrontational and less defensive environment in college classrooms. We outline the potential use of this analogy with a fictional case study in a university setting. Potential benefits and limitations of the approach are discussed.
Photonic bands, superchirality, and inverse design of a chiral minimal metasurface

Published: November 2019

Photonic band structures are a typical fingerprint of periodic optical structures, and are usually observed in spectroscopic quantities such as transmission, reflection, and absorption. Here we show that the chiro-optical response of a metasurface constituted by a lattice of non-centrosymmetric, L-shaped holes in a dielectric slab shows a band structure, where intrinsic and extrinsic chirality effects are clearly recognized and connected to localized and delocalized resonances. Superchiral near-fields can be excited in correspondence to these resonances, and anomalous behaviors as a function of the incidence polarization occur. Moreover, we have introduced a singular value decomposition (SVD) approach to show that the above mentioned effects are connected to specific fingerprints of the SVD spectra. Finally, by means of an inverse design technique we have demonstrated that the metasurface based on an L-shaped hole array is a minimal one. Indeed, its unit cell geometry depends on the smallest number of parameters needed to implement arbitrary transmission matrices compliant with the general symmetries for 2d-chiral structures. These observations enable more powerful wave operations in a lossless photonic environment.
Grating-assisted coupling enhancing plasmonic tip nanofocusing illuminated via radial vector beam

Published: November 2019

Tip-enhanced Raman spectroscopy (TERS) is a very useful method to achieve label-free and super-resolution imaging, and the plasmonic tip nanofocusing plays a decisive role for TERS performance. Here, we present a method to enhance the nanofocusing characteristic of a plasmonic tip integrated in a grating near the tip apex. Simulation results show that the grating near the tip apex can significantly improve the electric field intensity of the nanofocusing field compared with a conventional bare tip, under axial excitation of a tightly focused radial vector beam. The electric field enhancement characteristic is quantified in relation with the groove number of grating, excitation wavelength, period of grating, and numerical aperture of the micro-objective (MO). These simulation results could be a good reference to fabricate a plasmonic tip for TERS applications, which is an effective way to promote the development of tip-enhanced near-field optical microscopy.
Greatly amplified spontaneous emission of colloidal quantum dots mediated by a dielectric-plasmonic hybrid nanoantenna
Authors: Yang Guoce , Niu Yijie , Wei Hong , Bai Benfeng , Sun Hong-Bo
Published: November 2019

Optical nanoantennas can efficiently harvest electromagnetic energy from nanoscale space and boost the local radiation to the far field. The dielectric-metal nanogap is a novel design that can help to overcome the core issue of optical loss in all-metal nanostructures while enabling photon density of states larger than that in all-dielectric counterparts. This article reports that a crystalline spherical silicon nanoparticle on metal film (SiNPoM) nanoantenna can largely enhance the spontaneous emission intensity of quantum dots by an area-normalized factor of 69 and the decay rate by 42-fold compared with quantum dots on glass. A high total quantum efficiency of over 80%, including ~20% for far-field radiation and ~60% for surface plasmon polaritons, is obtained in simulation. Thanks to not only the low optical loss in dielectric nanoparticles but also the appropriate gap thickness which weakens the non-radiative decay due to the quenching from metal. Mie resonant modes additionally provide the flexible control of far-field emission patterns. Such a simple optical nanoantenna can be combined with various nanoscale optical emitters and easily extended to form large area metasurfaces functioning as active regions in light-emitting devices in applications such as advanced display, wireless optical communication, and quantum technology.

Published: November 2019

Background

Patients with peritoneal malignancy treated by cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) are prone to develop postoperative paralytic ileus (POI). POI is associated with significant increase in both morbidity and mortality. CRS and HIPEC commonly result in prolonged POI (PPOI). The objective was to clarify the extent of PPOI in patients treated by CRS and HIPEC for peritoneal malignancy.

Methods

This was a prospective multicenter study including patients operated with CRS and HIPEC at the Department of Surgery, Aarhus University Hospital, Denmark and the Peritoneal Malignancy Institute, Basingstoke, United Kingdom. A total of 85 patients were included over 5 months. Patients prospectively reported parameters of postoperative gastrointestinal function in a diary from post-operative day 1 (POD1) until discharge. PPOI was defined as first defecation on POD6 or later.

Results

Median time to first flatus passage was 4 days (range 1–12). Median time to first defecation was 6 days (1–14). Median time to removal of nasojejunal tube was 4 days (3–13) and 7 days (1–43) for nasogastric tube. Forty-six patients (54%) developed PPOI. Patients with PPOI had longer time to first flatus (p<0.0001) and longer time to removal of nasojejunal tube (p=0.001). Duration of surgery correlated to time to first flatus (p=0.015) and time to removal of nasogastric or nasojejunal tube (p<0.0001) but not to time to first defecation (p=0.321).

Conclusions

Postoperative gastrointestinal paralysis remains a common and serious problem in patients treated with CRS and HIPEC.

It argues that these four tablets are the oldest documents of the Hittite corpus, and that they were not created in Ḫattuša, but have been imported from elsewhere. Originally, they belonged to an older writing tradition, predating the establishment of Ḫattuša as the Hittite capital. This implies that the royal tablet collections in Ḫattuša do not reflect the very first beginnings of Hittite cuneiform, but only the start of a royal administration there. The typical Hittite ductus was already created in the 18th century BCE – in Kuššara, Nēša or elsewhere in Anatolia.
Das dritte und vierte Relief von Gundük
Authors: Aguilar Juan , Miglus Peter A.
Published: November 2019

The Gundük rock relief ensemble in a cave located in the northern highlands of Iraq is probably the oldest known example of its kind in the Near East. First reported in the 19th century but never accurately documented, unfortunately two of the three known reliefs were intentionally damaged beyond repair in the decades to follow. This article presents a new art-historical analysis of the preserved third relief as well as a fourth previously unknown carving, based on recent photogrammetric capture. The images can be dated to the Early Dynastic III or Early Akkadian period with motifs, stylistic details and a composition obviously deriving from then-contemporaneous art in southern Mesopotamia.
La prostitución en España: el limbo de la alegalidad
Authors: Boza Moreno Elena
Published: November 2019

El fenómeno de la prostitución es abordado desde diferentes perspectivas de la política criminal, sin embargo, en España el tratamiento que recibe el ejercicio de la prostitución, por personas mayores de edad y que prestan su consentimiento, dista mucho del de otros países que adoptan políticas abolicionistas o prohibicionistas. En este estudio, se muestra la realidad por la que atraviesa este sector, un vacío legal, que lo estigmatiza aún más. Si bien la explotación sexual de un tercero o el lucro proveniente del desempeño de este oficio por otra persona, está penado y perseguido, el libre ejercicio no está regulado a nivel estatal, quedando así en manos de los municipios su regulación a través de ordenanzas municipales que no hacen más que agravar la difícil situación que viven aquellas personas que ejercen la prostitución.

Published: November 2019

Jährlich wertet das WEF neben vielen anderen wettbewerbsrelevanten Faktoren auch die Infrastrukturqualität der Länder aus. Deutschland ist hier während der letzten zehn Jahre von Platz 1 (von etwa 140 berücksichtigten Ländern) auf Platz 10 zurückgefallen. Auch Dänemark verzeichnet eine Verschlechterung, die Polen können sich dagegen über einen deutlichen Qualitätszuwachs bei der Infrastruktur freuen.
Risikoloses Risiko
Authors: Bieta Volker , Milde Hellmuth
Published: November 2019

Gegenstand des Beitrages ist das Risikomanagement im Finanzsektor. Wir zeigen, wie man sich aus vielen riskanten Börsenwerten ein risikofreies Wertpapierportefeuille zusammen bauen kann. Dazu muss man zu jedem Börsenwert die maßgeschneiderte Gegenposition finden. Wenn diese Gegenposition in der Gesamtheit der existierenden Wertpapiere jedoch fehlt, muss sie neu produziert werden. Das nennt man „financial engineering“. Erfahrungsgemäß gibt es gute und schlechte Ingenieure. Alle Finanzmanager halten sich für Top-Experten. Dass sich viele dieser Leute stark überschätzt haben, trat in der Finanzkrise offen zu Tage. Ein Hinweis für den Leser: Im Anhang des Beitrages werden alle verbal abgeleiteten Ergebnisse auch mathematisch bestätigt.

Other-repetitions in Mandarin Chinese
Authors: Xiong Xiuzhen , Quan Lihong
Published: November 2019

It is generally acknowledged that other-repetitions have various functions in daily conversation. However, no research has yet been done to explore the relationship between their functions and responses. This study sets out to bridge this gap by investigating the functions of other-repetitions in Mandarin Chinese conversations as well as the relationships between the functions and the responses. Adopting the method of conversation analysis, the study shows that other-repetitions may be accomplished by no response, minimal response, and expanded response, which are highly related with the functions that other-repetitions fulfil. Specifically, (i) for other-repetitions serving as reactive tokens to show listenership, alignment, and registering of receipt, no response is needed; (ii) for other-repetitions indicating recipients’ understanding of the previous utterance, a further confirmation or minimal response is generally needed; and (iii) for other-repetitions with a rising intonation or particular stress of certain words indicating recipients’ failure in understanding what is uttered, they will be accomplished by expanded responses.
Medical experts as health knowledge providers
Authors: Shen Xingchen
Published: November 2019

The rise of wemedia in China has brought challenges to public health communication(PHC), such as the change in doctor-patient relations and the vulnerabilityof trust. As few researchers have touched upon the issue of identity constructionduring PHC in Weibo, this study aims to fill this gap and investigate one health informationprovider’s discursive construction of multiple identities in Weibo and itspragmatic effect on trust building. Through this study the author attempts to contributeto the existing scholarship on the dynamics of identity-relation constructionin wemedia and the pragmatic construction of trustworthiness in a PHC context.

El turismo rural una visión desde el ámbito internacional, nacional y del estado Táchira –Venezuela.
Authors: Zambrano Fernando , González Delymar , Peñaloza Rossy
Published: November 2019

El objetivo de esta investigación documental es identificar los principales elementos conceptuales del turismo rural en la

actualidad a nivel internacional, nacional y regional para promoverlo en el Estado Táchira. Internacionalmente es un generador de ingresos y  vector de intercambios entre el mundo rural y urbano mostrando los requisitos, estrategias y actividades concernientes. Latinoamérica se ha venido desarrollando para el progreso económico; Venezuela tiene una escasa tradición como país receptor de turistas; existen limitantes sociopolíticas, económicas y falta

de integración entre la comunidad, gobierno y empresa privada. El Táchira no se ha desarrollado en éste ámbito; es un Estado agrícola con diversos atractivos, que por su posición geográfica posee la frontera más viva de Latinoamé rica, esto explica su potencial para convertirse en un destino turístico una vez realizados los diagnósticos y proyectos para el desarrollo rural sostenible y sustentable entre la comunidad, los entes públicos y privados para el crecimiento del Estado.
