IPOs, the Level of Private Equity Engagement and Stock Performance Matters: Empirical Evidence from Germany

We extend the existing IPO literature by focusing on stock performance matters combined with companies’ ownership structures and, in particular private equity ownerships capital engagement, for the first time. The unique dataset on German IPOs from 2004 to 2014 allows us to identify companies’ ownership structures before and after the IPO. We address on mainly two questions in our work. First, do companies that were (partially) owned by private equity investors prior the IPO show lower short-term stock returns after the IPO than companies without prior investments of private equity investors? Second, is the companies’ long-term stock performance after the IPO better when private equity investors’ involvement is higher at the IPO? We find that the level of private equity investors’ shareholding prior the IPO predicts future returns, particularly in the longer run. Furthermore, we document that the stronger the private equity investors reduce their engagement the stronger is the performance of the issued stock. Our findings are robust to IPOs’ industrial sectors.
The Impact of a Living Learning Center on Students' Academic Success and Persistence

Beginning in the 1980s and continuing into the new century, internal and external critics of higher education have focused on the quality of undergraduate education in colleges and universities in the United States (Boyer, 1987, 1990; Astin, 1993; Wingspread Group, 1993). In a three-year span in the mid-1980’s, more than 30 national reports and approximately 300 task forces called for changes to improve the quality of undergraduate education (Cross, 1993). Today, legislators, the public, and those within the academy criticize the quality of undergraduate education based on student learning, retention, and graduation rates. As a response to such criticism, many institutions have sought to regain public confidence by improving undergraduate education (Schroeder and Hurst, 1996). Residential life departments at colleges and universities across the country have responded to this focus on undergraduate education by increasing their focus on student learning through the implementation of programs to bridge the gap between curricular and cocurricular education. These programs, generally referred to as learning communities or living learning centers (LLCs), resemble a return to the early roots of American higher education and the Oxford and Cambridge models of residential living The Impact of a Living Learning Center on Students’ Academic Success and Persistence
A Review: Thermoelectric Generators in Renewable Energy

In this paper, the role of thermoelectric generators (TEGs) in conversion of geothermal energy into electrical energy has been presented. In addition, the structures of the TEGs used in the electrical energy production have been reported. The TEGs directly convert the thermal energy into the electrical energy. The thermoelectric (TE) technology is used in both the air–conditioning and the electrical energy generation. Also, the TE technology is eco–friendly as it has no greenhouse gas emissions, durable due to the absence of moving parts and is silent. However, the conversion efficiency of the thermoelectric modules (TEMs) used commercially is less than about 10%.
Sarcotoxin II from the flesh fly Sarcophaga crassipalpis (Diptera): A comparison of transcript expression in diapausing and nondiapausing pupae

Many stress-induced genes, including those related to the insect humoral immune response, are upregulated during diapause even in the absence of stress. We further test the relationship between stress genes and diapause in Sarcophaga crassipalpis by cloning sarcotoxin II, a member of the attacin family, and examining its expression pattern in relation to pupal diapause. Unlike several other stress-related genes, sarcotoxin II is not developmentally upregulated during diapause, but it remains fully responsive to immune challenge. Interestingly, the elevation of sarcotoxin II mRNA in response to body wall injury, but not immune challenge, is initiated more slowly and persists longer in diapausing pupae than in nondiapausing individuals.
Comorbid Disorders in Outpatients with Major Depressive Disorder and Their Sociodemographical Aspects

Son yıllarda, major depresif bozukluk (MDB) kronikleşmeye eğilimi, tedaviye direnci, etkilediği kişi üzerindeki tüketici semptomatolojisi ve bunlara bağlı yüksek sağlık harcamalarına yol açması nedeniyle, sağlık sistemi üzerinde giderek artan bir yük olmaya başlamıştır. Major depresyon ile birlikteliği bildirilen, diğer ekhastalıkların da bu yüke katkıda bulunduğu düşünülmektedir. Bu çalışmanın amacı major depresyon ile ilgili veri havuzuna, sonraki muhtemel MDB etyolojisine yönelik çalışmalara katkıda bulunmak ve MDB’e ait sağlık harcamaları için bir zemin hazırlamaktır. Bu makale ile Türkiye’de yer alan bir kıyı kenti olan Mersin yöresinde bulunan MDB hastalarının sosyodemografik özellikleri ve bu hastalarda izlenen ekhastalıklara ait verilerimizin değerlendirilmesini sunmaktayız. Bu çalışmada, Mersin Üniversitesi Tıp Fakültesi Ruh Sağlığı ve Hastalıkları Anabilim Dalının arşivleri detaylı bir şekilde taranmış ve MDB tanısı alan hastaların kayıtlarından yaş, cinsiyet, medeni durum, eğitim durumu, meslek, HAM-A (Hamilton Anksiyete Ölçeği) ve HAM-D (Hamilton Depresyon Derecelendirme Ölçeği) değerleri ve ekhastalık verileri elde edilmiştir. 64 (%20) erkek, 247 (%80) kadın olmak üzere toplam 311 hasta kaydı çalışmaya dahil edilmiştir. Sonuçlarımız hastaların %80.7 (251)’inde sadece major depresif bozukluk olduğunu, kalan %19.3 (60)’ında da bir ekhastalık olduğunu açığa çıkarmıştır. Ayrıca eğitim seviyesinde düşüşle beraber konulan MDB tanısın oransal olarak azaldığı ve MDB’a en sık görülen ekhastalığın panik bozukluk olduğu saptanmıştır. Depresif bozukluktaki ekhastalık depresif hecmenin süresini, genel işlevselliği ve tedaviye yanıtı etkiler. Bu nedenle major depresif bozukluk ve ekhastalıkları tanımak önemlidir.
LLAMA : nuclear stellar properties of Swift-BAT AGN and matched inactive galaxies.

In a complete sample of local 14–195 keV selected active galactic nuclei (AGNs) and inactive galaxies, matched by their host galaxy properties, we study the spatially resolved stellar kinematics and luminosity distributions at near-infrared wavelengths on scales of 10–150 pc, using SINFONI on the VLT. In this paper, we present the first half of the sample, which comprises 13 galaxies, eight AGNs and five inactive galaxies. The stellar velocity fields show a disc-like rotating pattern, for which the kinematic position angle is in agreement with the photometric position angle obtained from large scale images. For this set of galaxies, the stellar surface brightness of the inactive galaxy sample is generally comparable to the matched sample of AGN, but extends to lower surface brightness. After removal of the bulge contribution, we find a nuclear stellar light excess with an extended nuclear disc structure, which exhibits a size-luminosity relation. While we expect the excess luminosity to be associated with a dynamically cooler young stellar population, we do not typically see a matching drop in dispersion. This may be because these galaxies have pseudo-bulges in which the intrinsic dispersion increases towards the centre. And although the young stars may have an impact in the observed kinematics, their fraction is too small to dominate over the bulge and compensate the increase in dispersion at small radii, so no dispersion drop is seen. Finally, we find no evidence for a difference in the stellar kinematics and nuclear stellar luminosity excess between these active and inactive galaxies.
Human Capital and Development Accounting: New Evidence from Immigrant Earnings

This paper constructs quality adjusted labor inputs for 50 countries, disaggregated into 7 school levels. Our estimates of labor qualities are based on the wages of immigrants observed in 11 host countries. Based on these estimated labor inputs, we address two questions. First, we estimate the contribution of human capital to variation in output per worker across countries. We find that labor quality accounts for 12% of this variation, while capital and labor inputs jointly account for 43%. Second, we study the cross-country variation in the relative productivities of skilled and unskilled workers. Since we find little evidence of variation in the relative qualities of skilled versus unskilled workers, we conclude that more educated countries employ more skill biased technologies.
Estimating Body Mass from the Astragalus in Mammals

Astragalar fossils have been intensively studied as an indicator of the functional morphology and phylogenetic relationships of mammals. However, relatively few studies have investigated the relationship between astragalar size and body mass, usually with a focus on a particular taxonomic group. Here, univariate and multiple regression models are used to analyze the relationship between astragalar size and body mass based on an extensive sample of extant land mammals (11 orders, 48 species, 80 individuals; body mass ranging from 18 g to 3.4 t). The analyses revealed the size of the tibial trochlea to be a better predictor of body mass than the total size of the astragalus. Based on these results, estimates of the body mass of several Paleogene land mammals were calculated and compared to those of previous studies. Thus, for example, the body mass of “Baluchitherium”, the largest terrestrial mammal known to date, was estimated at about 10–15 t.
A Preliminary Performance Assessment for Salt Disposal of High-Level Nuclear Waste - 12173

A salt repository is one of the four geologic media currently under study by the U.S. DOE Office of Nuclear Energy to support the development of a long-term strategy for geologic disposal of commercial used nuclear fuel (UNF) and high-level radioactive waste (HLW). The immediate goal of the generic salt repository study is to develop the necessary modeling tools to evaluate and improve the understanding of the repository system response and processes relevant to long-term disposal of UNF and HLW in a salt formation. The current phase of this study considers representative geologic settings and features adopted from previous studies for salt repository sites. For the reference scenario, the brine flow rates in the repository and underlying interbeds are very low, and transport of radionuclides in the transport pathways is dominated by diffusion and greatly retarded by sorption on the interbed filling materials. I-129 is the dominant annual dose contributor at the hypothetical accessible environment, but the calculated mean annual dose is negligibly small. For the human intrusion (or disturbed) scenario, the mean mass release rate and mean annual dose histories are very different from those for the reference scenario. Actinides including Pu-239, Pu-242 and Np-237 are major annual dose contributors, and the calculated peak mean annual dose is acceptably low.
The Savannas: An integrated synthesis of three major competing paradigms

The coexistence between trees and grasses in the savannas is a contentious issue. Although necessary scientific efforts have been done, unfortunately such efforts have given rise to contrasting theories and models. This review provides a synthesis of these theories how they influenced our understanding of the savannas over time. The review found that while the equilibrium theory predicts savannas as stable ecosystems regulated by natural mechanisms such as root niche partitioning, such ideas have been disputed in favour of non-equilibrium framework. The latter suggests that savannas are unstable ecosystems largely regulated by stochastic dynamics such as inter annual rainfall variations and episodic environmental shocks such as fire and overgrazing which result in an ecosystem oscillation between grass dominated and woody dominated phases in time and space. On the other hand the disequilibrium paradigm argues that savannas are unnatural ecosystems formed as a result of anthropogenic disturbances such as fire and grazing that buffer the ecosystem from complete domination by either trees or grasses. This review demonstrates that the savannas still lack a unifying theoretical framework. The current one is characterized by conflicting, contradictory, diverging ideas. Such revelations call for a need to develop a unifying theoretical framework for the savannas.
Evaluation of phenolic compounds of two Lygeum spartum L. cytotypes

Lygeum spartum represents a natural barrier in the Algerian high plateaus against the advance of sand and the desertification. The plant is of interest due to its tolerance to environmental stress. There are two levels of ploidy in this species; the diploid cytotype 2n = 16 which is confined in the locality of Ain Benkhllil and the polyploid cytotype 2n = 40 which thrives in semi-arid climates and has a large ecologic plasticity. The The aim of this study was the evaluation of the phenolic compounds and flavonoids in both cytotypes. The antioxidant activity was also measured with results showing differences in the level of phenolic compounds; thus, these compounds could serve as biomarkers to distinguish the two cytotypes. Key words: Lygeum spartum L, total phenols, flavonoids, 2,2-diphenylpicrylhydrazyl (DPPH), lipid peroxidation.

The work is motivated by non-holonomic and sub-Riemannian geometry of mechanical systems on finite dimensional manifolds.Two examples are given.
Economic sentiment and the recession depth in Croatia: a structural break analysis

This paper aims to shed some light on the cause-and-effect relationship between economic sentiment and the GDP growth rates in Croatia. The authors focus on the Economic Sentiment Indicator data gathered from Business Surveys and question whether its comovement with GDP is time-stable. Applying the Andrews-Quandt and Bai-Perron structural break tests, it is found that the interdependence between the two observed variables changes substantially in the dawn of the economic crisis in 2008. That way the sample period is split into two subparts. The pre-recession period offers no evidence of Granger causality in any direction, while the recession period strongly confirms economic sentiment as a valuable predictor of actual economic tendencies.
Update on evaluation of enhanced darkfield microscopy and hyperspectral mapping for analysis of airborne nanoparticulate collected on filter-based media

Current best-known methods for engineered nanomaterial (ENM) exposure assessment in occupational environments include the capture of airborne ENMs onto filter media. The current standard method for the analysis of filter media is direct visualization via transmission electron microscopy (TEM) for particle sizing, count, and morphology, often coupled with energy-dispersive x-ray spectroscopy (EDS) for compositional analysis. This method is low-throughput, expensive, and timeand resource-intensive. Enhanced darkfield microscopy (EDFM) with hyperspectral imaging (HSI) and mapping analysis is being evaluated as a high-throughput screening technique to rapidly identify ENMs of interest on filter media samples. We are exploing use of EDFM-HSI for the detection, characterization, and quantitation of ENMs caputred on filters with the intent to develop a standardized method and analytical protocols.
Long-term ensemble forecast of snowmelt inflow into the Cheboksary Reservoir under two different weather scenarios

Abstract. A long-term forecasting ensemble methodology, applied to water inflows into the Cheboksary Reservoir (Russia), is presented. The methodology is based on a version of the semi-distributed hydrological model ECOMAG (ECOlogical Model for Applied Geophysics) that allows for the calculation of an ensemble of inflow hydrographs using two different sets of weather ensembles for the lead time period: observed weather data, constructed on the basis of the Ensemble Streamflow Prediction methodology (ESP-based forecast), and synthetic weather data, simulated by a multi-site weather generator (WG-based forecast). We have studied the following: (1) whether there is any advantage of the developed ensemble forecasts in comparison with the currently issued operational forecasts of water inflow into the Cheboksary Reservoir, and (2) whether there is any noticeable improvement in probabilistic forecasts when using the WG-simulated ensemble compared to the ESP-based ensemble. We have found that for a 35-year period beginning from the reservoir filling in 1982, both continuous and binary model-based ensemble forecasts (issued in the deterministic form) outperform the operational forecasts of the April–June inflow volume actually used and, additionally, provide acceptable forecasts of additional water regime characteristics besides the inflow volume. We have also demonstrated that the model performance measures (in the verification period) obtained from the WG-based probabilistic forecasts, which are based on a large number of possible weather scenarios, appeared to be more statistically reliable than the corresponding measures calculated from the ESP-based forecasts based on the observed weather scenarios.
Higher Education Lecturers’ Lived Experience of Going Public in MOOCs

Academics in higher education are used to having their research publications reviewed and openly scrutinized. Teaching in higher education has traditionally been an individual academic’s activity that has taken place in a closed classroom. However, the introduction of open education, particularly massive open online courses (MOOCs) has challenged this. In MOOCs, lectures are recorded and made public for thousands of course participants to view. This study investigates, via semi-structured interviews, how 20 lecturers of 10 MOOCs at six Swedish Universities have experienced this. All have joined the projects voluntarily, but a few have done so with some ambivalence. For them, standing in front of the camera, publishing material and, to some extent, losing control of the course content was scary at the beginning of the projects. Overall, the lecturers overcame this and thought that it was a good opportunity to reach many students, as well as a way to keep up with the changing requirements for teaching in higher education.
A Review On Data Mining Process In Healthcare Department To Identify The Frequently Occurring Diseases

Data mining is a process of analyzing large volumes of data to extract the useful knowledge from it. Data mining techniques is applied on medical data to improve the service in healthcare department. Availability of electronics data in the medical institutions are a good opportunity to the researchers to develop in all the aspects. It helps to know the diseases which are occurring frequently and how to solve it with out disturbing the other related work. This paper discussed a novel technique to identify the frequently occurring diseases using different visualized aids.
Disruption of Dark Matter Substructure: Fact or Fiction?

Accurately predicting the demographics of dark matter (DM) substructure is of paramount importance for many fields of astrophysics, including gravitational lensing, galaxy evolution, halo occupation modelling, and constraining the nature of DM. Because of its strongly non-linear nature, DM substructure is typically modelled using N-body simulations, which reveal that large fractions of DM subhaloes undergo complete disruption. In this paper, we use both analytical estimates and idealized numerical simulations to investigate whether this disruption is mainly physical, due to tidal heating and stripping, or numerical (i.e. artificial). We show that, contrary to naive expectation, subhaloes that experience a tidal shock Delta E that exceeds the subhalo's binding energy, vertical bar E-b vertical bar, do not undergo disruption, even when Delta E/vertical bar E-b vertical bar is as large as 100. Along the same line, and contrary to existing claims in the literature, instantaneously stripping matter from the outskirts of a DM subhalo also does not result in its complete disruption, even when the instantaneous remnant has positive binding energy. In addition, we show that tidal heating due to high-speed (impulsive) encounters with other subhaloes ('harassment') is negligible compared to the tidal effects due to the host halo. Hence, we conclude that, in the absence of baryonic processes, the complete physical disruption of CDM substructure is extremely rare and that most disruption in numerical simulations therefore must be artificial. We discuss various processes that have been associated with numerical overmerging and conclude that inadequate force softening is the most likely culprit.
Todd’s Syndrome: An Arabic Single Case of Prolonged Motor Impairment Presentation with Neuropsychological Tests Validation

This paper presents a rare case of postictal hemiplegia for a prolonged period. The patient has no brain abnormality of vascular nature or any evidence of abnormality on MRI and EEG, but he had a single GTC seizure two months ago. This is the first Arabic case report of prolonged Todd’s syndrome. The patient has no psychological problems either. We tested the hypothesis that there is no motivation factor in his presentation. The patient was totally normal on cognitive neuropsychological tests and on two Symptoms Validity Tests (SVT). This is also the first time SVTs are used with Todd’s syndrome, as far as we are aware. This rare case raises awareness and enhances our knowledge of clinical presentations, reducing the amount of diagnostic procedures and unnecessary therapies. It also helps clinicians to avoid ‘psychologising’ the clinical presentation as hysteria or psychogenic hemiplegia, in the absence of such evidence.
The value of Kikuyu foggage for overwintering dry ewes

Kikuyu (Pennisetum clandestinum) is a summer growing tropical pasture species well adapted to the Midlands of KwaZulu-Natal. Kikuyu foggage (standing hay) could play an important role in a fodder flow programme to sustain dry ewes during late winter after their lambs have been weaned in mid-winter. The potential of kikuyu foggage to supply in the feed requirements of dry ewes was evaluated over four winter periods. The foggage was obtained by closing off the kikuyu to grazing during either late January or late February. The foggage was grazed for eight weeks, from mid-July to mid-September, using either strip or continuous grazing systems. Closing off date did not significantly influence the chemical composition of the material on offer. The ewes in the different treatments lost between 4.7 and 10.3% of their initial body weight over the grazing period. In vitro digestible organic matter (IVDOM) of the foggage declined as winter progressed and was positively correlated with the body weight loss of the ewes. Foggage utilization varied between 36.7 and 43.5%, indicating a high proportion of fodder wastage. The body weight loss of the dry ewes during the grazing period suggested that kikuyu foggage in the KwaZulu-Natal Midlands was unable to sustain the body weight of the dry ewe.
