Initial Coin Offerings (ICOs) als Instrumente der Unternehmensfinanzierung und deren Einordnung in die bestehende finanzwirtschaftliche Taxonomie

Initial Coin Offerings (ICOs) haben in jüngerer Vergangenheit ein bedeutsames Volumen im Rahmen der Emissionsfinanzierung erlangt. Sie basieren im Wesentlichen auf der Blockchain-Technologie, besitzen aber gleichzeitig typische Charakteristika von Finanzierungsinstrumenten aus der „analogen Welt“. Dieser Beitrag stellt die Varianten von Coins bzw. Token zunächst dar und zeigt darauf aufbauend die inhaltliche Verbindung zu analogen Finanzierungsinstrumenten und deren Systematisierung im Kontext der Unternehmensfinanzierung auf. Dies ermöglicht sowohl Investoren als auch Emittenten einen Vergleich zwischen diesen neuartigen Finanzierungsalternativen und den klassischen Finanzierungsinstrumenten. Unser Beitrag zeigt, dass auch in der Welt der Token der Dreigliederung aus Eigen-, Fremdund Mezzaninfinanzierung im Hinblick auf ihre Ausgestaltung gefolgt werden kann, die Instrumente jedoch durchgehend der Außenfinanzierung zuzuordnen sind. Eine besondere hybride Stellung nehmen Nutzungstoken ein, die bereits aufgrund ihrer Grundstruktur im Vorhinein nicht eindeutig einer Kapitalart zugeordnet werden können.
Dynamics of hard and soft colloids at aqueous interfaces

This thesis examines interfacial colloidal dynamics in two separate aqueous systems. The first part aims to improve understanding of thermoresponsive microgel-stabilised emulsions. Many emulsion properties are determined by the behaviour and drainage dynamics of the thin films that form between droplets. This study reveals these drainage dynamics, achieved through observing a model thin film of PNiPAM microgel solution in air. We explore why, as other studies have shown, less cross-linked microgels stabilise emulsions more effectively than more cross-linked microgels, concluding that both adsorption dynamics and particle rearrangement under pressure play a role. Through a simple calculation, we are able to estimate the conformation of microgels at the interface, showing that microgel concentration in bulk determines the concentration at interface due to differences in adsorption kinetics, and microgel excess does not play a role. The second part of the thesis investigates behaviour of spherical colloidal particles within an Aqueous Two-Phase System (ATPS) composed of non-mixing polymer solutions of fish gelatin and dextran, with applications in low-fat foods. Additionally, the very low surface tension of these systems allows studing fast interfacial processes at experimentally accessible timescales. In this work, we examine adsorption dynamics of spherical particles, observing for the first time the theoretically-predicted exponential ‘snap-in’ stage of particle adsorption. Surprisingly, even at this low surface tension, a slower logarithmic relaxation is subsequently observed which at the oil/water interface is ascribed to pinning of the contact line on surface defects.

Social Media Browsing and Adolescent Well-Being: Challenging the “Passive Social Media Use Hypothesis”

A recurring hypothesis in the literature is that “passive” social media use (browsing) leads to negative effects on well-being. This preregistered study investigated a rival hypothesis, which states that the effects of browsing on well-being depend on person-specific susceptibilities to envy, inspiration, and enjoyment. We conducted a three-week experience sampling study among 353 adolescents (13-15 years, 126 assessments per adolescent). Using an advanced N=1 method of analysis, we found sizeable heterogeneity in the associations of browsing with envy, inspiration, and enjoyment (e.g., for envy ranging from β = -.44 to β = +.71). The Passive Social Media Use Hypothesis was confirmed for 20% of adolescents and rejected for 80%. More adolescents with browsing-induced envy experienced negative effects on affective well-being (25%) than adolescents with no browsing-induced envy (13%). Conversely, more adolescents with browsing-induced enjoyment experienced positive effects on affective well-being (47%) than adolescents with no browsing-induced enjoyment (9%).
Robust Localization With Distance-Dependent Noise and Sensor Location Uncertainty

This letter investigates the localization problem with distance-dependent noise and sensor location uncertainty. The formulated localization problem is very challenging and non-convex due to the coupled distance-dependent noise variance and the location uncertainty, as well as the nonlinearity in the distance function. A low complexity two-step algorithm that incorporates maximum likelihood and Gaussian message passing (ML-GMP) algorithms is proposed to estimate the target location. It first transforms the distance-dependent noise into distance-independent one by introducing the distance as an intermediate parameter and adopting ML criterion for estimation. A low complex GMP algorithm is then followed to deal with the sensor location uncertainties and estimate the target location. Convergence of the proposed algorithm is proved, and simulation results show the proposed ML-GMP algorithm can approach the Bayesian Cramer-Rao bound (BCRB) and outperforms the other existing algorithms.
Graduates Employability: Has the Expansion of the University Sector in Uganda improved Employment Prospects for Graduates? Employers and Lecturers Perspective

Given the increasing private and public cost of university education, households and nations are getting more interested in that type of education which has high potential for employment. This study explores how the expansion of the university sector in Uganda is related to graduates’ employability. The study was guided by three objectives, namely: To find out whether expansion of the university sector in Uganda is related to available options of employment for graduates; To establish whether the expansion of the university sector in Uganda is related to adequacy of skills which graduates need in the world of work; To examine whether the expansion of the university sector in Uganda is related to the duration which graduates take before getting employed after graduation. Mainly relying on the constructivist research paradigm, the study used a cross sectional and correlational research design. Both qualitative and quantitative approaches were used in data collection and data analysis. Using a questionnaire and interviews, data were collected from 244 university lecturers, 9 Deans of Faculty, 18 Heads of Department, and 9 Human Resource Managers who represented employers. The study found out that expansion of the university sector in Uganda has a relationship with options for employment of graduates in the world of work. The expansion of the university sector in Uganda is associated with adequacy of skills for employment which are acquired by university graduates. These findings also show that expansion of the university sector in Uganda is related to the duration which graduates take to get employment after graduation. Key words: Expansion, university sector, graduates’ employability, labour markets.
Evaluation of immunohistochemical expression of epithelial– mesenchymal transition markers E-cadherin, Twist and Snail in oral submucous fibrosis and their possible association with malignant transformation

Background: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition of the oral mucosa, predominantly seen in people of Asian descent. The reported malignant transformation rate of OSMF is 7%–13%. In the context of the understanding progression of OSMF, the study of prime molecular expressions is essential. Various markers have received more attention, one of them is E-cadherin. Various factors which promote epithelial–mesenchymal transition (EMT) and inhibit E-Cadherin include Snail1, Snail2, Twist and EF1/ZEB1. The intended study was undertaken to evaluate the possible role of E-cadherin and its regulatory markers Twist1 and Snail1 in OSMF. Aims and Objectives: To evaluate the expression of E-cadherin, Twist1 and Snail1 in OSMF To evaluate their possible association with malignant transformation of OSMF. Materials and Methods: Histologically proven 20 cases of each OSMF with and without dysplasia were taken as the study group, 20 normal mucosa as control group and were subjected for immunohistochemical (IHC) expression with E-cadherin, Twist1 and snail1. Results: Immunohistochemical expression of all the three markers showed statistically significant expression of all the three markers. Intensity and percentage of staining between the groups were statistically significant for E-cadherin between normal oral mucosa (NOM) and OSMF with dysplasia (OSMFD), no significance was found between NOM and OSMF, whereas Snail1 and Twsit1 were statistically significant between NOM and OSMF and also between NOM and OSMFD. However, no significance was found for all the three markers when compared between the groups OSMF and OSMFD. Conclusion: The increased expression of Snail1 and Twist1 with concomitant loss of E -cadherin in OSMF suggests the role of the EMT.
Energy forecast for mobile photovoltaic systems with focus on trucks for cooling applications

For a viable and commercial attractive integration of vehicle integrated photovoltaic applications (ViPVs) energy forecasting is required as a foundation for business case calculation. The developed algorithm facilitates the forecast of annual power distribution and solar energy yield along any given track tested on a German use case. A high temporal and spatial resolution of the meteorological database providing ambient temperature, wind speed, and global horizontal irradiance was determined as a necessity to preserve the irradiance distribution and consequently the power distribution available throughout the year. For ViPV module temperature, respectively, module efficiency benefits strongly from head wind. As a consequence, the performance of ViPV under motion was identified as superior to non‐mobile PV installations. The potential annual energy yield of the three showcasing commercial semi‐trailer lorries operating in Germany is identified to be 3–7 MWh depending on the used cell technology. The potential energy gain due to head wind cooling is estimated to be 20–75 kWh per trailer and year. Copyright © 2017 John Wiley & Sons, Ltd.

The study investigated digital literacy of university students as a pointer to use of library database e-resources in Nigeria. Two objectives and two hypotheses where formulated which are: Find out the relationship between digital literacy and use of library electronic resources, to find out the relationship between digital literacy of undergraduate students in federal university and their use of library electronic resources, there is no significant relationship between digital literacy of undergraduate students and their use of library electronic resources and there is no significant relationship between digital literacy of undergraduate students in Federal university and their use of library electronic resources. The design of the study is correlational survey. The population of this study is 18,862 undergraduate students who are registered library users of the three selected universities for this study. The sample for the study comprised one thousand eight hundred and eighty-seven (1,887) undergraduate students. Purposive sampling was used to select one federal, state and private university in Edo state. Descriptive statistics (frequency count, percentages and pearson coefficient, weighted response average) was used to answer all the research questions and Pearson correlation was used in testing the hypotheses. The null hypotheses were tested at 0.05 level of significance. The decision rule was: reject null hypotheses if probability value (Sig-value) is less than 0.05, otherwise, do not reject null hypotheses. Findings show that … There is a significant low positive relationship between digital literacy of undergraduate students and their use of library electronic resources and there is a significant low positive relationship between digital literacy of undergraduate students in Federal university and their use of library electronic resources. Recommendations are… Orientation services should be organized for fresh students on how to effectively access the available electronic digital resources in the university. The orientation should be aimed at improving students’ digital literacy and helping them to acquire the requite abilities needed to effectively use e-resources and librarians in Federal universities should guide students and other library visitor in the use of library electronic resources. Standby librarians should be allotted to the digital section of the library for such purpose.
induced sarcoplasmic reticulum Ca 2+ release kinetics during β- adrenergic stimulation

We aimed to define the relative contribution of both PKA and Ca 2+ /calmodulin-dependent protein kinase II (CaMKII) cascades to the phosphorylation of RyR2 and the activity of the channel during β-adrenergic receptor (βAR) stimulation. Rat hearts were perfused with increasing concentrations of the β-agonist isoproterenol in the absence and the presence of CaMKII inhibition. CaMKII was inhibited either by preventing the Ca 2+ influx to the cell by low [Ca]o plus nifedipine or by the specific inhibitor KN-93. We immunodetected RyR2 phosphorylated at Ser2809 (PKA and putative CaMKII site) and at Ser2815 (CaMKII site) and measured [ 3 H]-ryanodine binding and fast Ca 2+ release kinetics in sarcoplasmic reticulum (SR) vesicles. SR vesicles were isolated in conditions that preserved the phosphorylation levels achieved in the intact heart and were actively and equally loaded with Ca 2+ . Our results demonstrated that Ser2809 and Ser2815 of RyR2 were dose-dependently phosphorylated under βAR stimulation by PKA and CaMKII, respectively. The isoproterenolinduced increase in the phosphorylation of Ser2815 site was prevented by the PKA inhibitor H-89 and mimicked by forskolin. CaMKII-dependent phosphorylation of RyR2 (but not PKA-dependent phosphorylation) was responsible for the β-induced increase in the channel activity as indicated by the enhancement of the [ 3 H]-ryanodine binding and the velocity of fast SR Ca 2+ release. The present results show for the first time a dose-dependent increase in the phosphorylation of Ser2815 of RyR2 through the PKA-dependent activation of CaMKII and a predominant role of CaMKII-dependent phosphorylation of RyR2, over that of PKA-dependent phosphorylation, on SR-Ca 2+ release during βAR stimulation.
Social Media Use in Emerging Adults: Investigating the Relationship With Social Media Addiction and Social Behavior

Online interactions are becoming ubiquitous as the technological era progresses, especially for young people who have grown up in the digital age. As of 2018, 45% of teenagers claimed to be online “almost constantly” (Anderson & Jiang, 2018). Researchers are beginning to investigate how using online platforms for social interactions may be shaping people’s personal and social lives. The present study focused particularly on the social lives of emerging adults and explored whether and how individual’s time spent on social media impacts social behaviors and tendencies as well as whether these altered social behaviors lead to social media addiction.
Continuous power flow for hybrid AC/DC microgrid considering uncertainty of intermittent DG output

The uncertainty of intermittent distributed generator (DG), lack of a slack bus and the bidirectional flow of AC/DC subsystems are unfavourable to security and stability of island AC/DC hybrid microgrid, making the traditional power flow methods difficult to apply. To this end, this study proposes a continuous power flow (CPF) method for this microgrid considering intermittent DG. Firstly, the discrete method based on Wasserstein optimal distance metric is proposed to construct joint scenarios of wind and photovoltaic generation output. Further, a unidirectional prediction-correction CPF is proposed according to the different regions of changing load. This method only needs prediction-correction calculation for the subsystem where the load is changed, while another subsystem uses conventional power flow. Moreover, the key points of initial point and the correction calculation are summarized as determined equations, and accelerated LM algorithm with non-monotone linear search (ALMNL) is proposed to reduce calculation complexity and improve the convergence speed. Finally, the simulation results on the test system prove the feasibility and effectiveness of the proposed method The algorithm provides a new method and theoretical support for CPF of power system with intermittent DG, and the voltage stability analysis and operation of AC/DC hybrid system and narrow flow solution microgrid system. The proposed method greatly reduces the complexity of CPF while considering the influence of DG output, ensures the calculation accuracy and greatly reduces the calculation time. The uniformity of the solution of the tidal equations has global convergence and faster local convergence speed simultaneously.
The forms and meanings of grammatical markers support efficient communication

Significance Grammatical marking of features such as number, tense, and evidentiality varies widely across languages. Despite this variation, we show that grammatical markers support efficient information transfer from speakers to listeners. We apply a formal model of communication to data from dozens of languages and find that grammatical marking achieves a near-optimal balance between maximizing informativeness and minimizing code lengths. Our approach shows how general information-theoretic principles can capture variation in both form and meaning across languages. Functionalist accounts of language suggest that forms are paired with meanings in ways that support efficient communication. Previous work on grammatical marking suggests that word forms have lengths that enable efficient production, and work on the semantic typology of the lexicon suggests that word meanings represent efficient partitions of semantic space. Here we establish a theoretical link between these two lines of work and present an information-theoretic analysis that captures how communicative pressures influence both form and meaning. We apply our approach to the grammatical features of number, tense, and evidentiality and show that the approach explains both which systems of feature values are attested across languages and the relative lengths of the forms for those feature values. Our approach shows that general information-theoretic principles can capture variation in both form and meaning across languages.
Facile and clean electrochemical synthesis of new acetaminophen derivatives through electrochemical oxidation of acetaminophen in the presence of thiouracil derivatives

ABSTRACT The electrochemical oxidation of acetaminophen (1a) is carried out in the presence of thiouracil derivatives (3a–c), as nucleophiles, in an acetate buffer solution (0.15 M, pH 5) mixed with Dimethylformamide (DMF) using cyclic voltammetry and coulometry under a constant potential. The results obtained indicate that N-acetyl-p-benzoquinone-imine derived from acetaminophen participates in a 1,4-Michael-type addition reaction with thiouracils to form the corresponding acetaminophen derivatives (4a–c) in good yields and with high purities using a facile, catalyst-free, and one-pot electrochemical method using three carbon electrodes in an undivided cell under mild conditions. The products obtained were characterized after purification by IR, 1H NMR, and 13C NMR spectroscopies, and by the elemental analysis method. GRAPHICAL ABSTRACT
HAND EXERCISE USING A RUBBER BALL INCREASES GRIP STRENGTH IN PATIENTS WITH NON-HAEMORRHAGIC STROKE

Stroke can cause various degrees of disturbance, such as decreased muscle tone, loss of sensibility in some parts of the body, limits the ability to move the affected limbs and incapacity in certain activities. This study aimed to identify the effect of hand exercises using a rubber ball on muscle strength in patients with non-haemorrhagic stroke. we measure handgrip strengths of the respondents as it reflects the muscle strength and integrity functions of the upper limbs. The sample in this study was 40 patients with one-sided upper extremity paresis causing by ischaemic stroke. A pre-experimental method with one group pre-post-test design was used in this study. The respondents were given hand exercise using a ragged rubber ball for seven days twice a day. Handgrip strength of were measured by a handgrip dynamometer before and after the interventions. The Wilcoxon signed-rank test was performed with p -value of 0.000 (ά<0, 05) which means that hand exercises using a rubber ball does increase the muscle strengths of the upper extremity. We suggest that hand therapy using a ragged rubber ball can be used as an alternative for motor exercise in post-stroke patients.
