Investigation of the Thermal State of Parts to Justify the Possibility of Additive Forming of Nitinol Blanks In Situ
Authors: Goncharov A.L. , Chulkov I.S. , Titarev E.K.
Published: May 2021

In this paper, the substantiation of the possibility of additive forming of nitinol billets by simultaneous surfacing of two titanium and nickel wires with an electron beam in vacuum is given. The method of mathematical modeling shows the possibility of forming several molten pools of liquid metal on the bead being deposited immediately behind the main pool for remelting the formed material. The modes of the electron beam for the formation of the main and two additional remelting pools due to the deflection of the beam are determined taking into account the technological capabilities of the installation. The residence time of the metal in the liquid state is calculated for various additive forming modes. Remelting makes it possible to increase the residence time in the liquid state by a multiple of the molten pools number. This significantly improves the conditions for mixing the raw materials and reduces the heterogeneity of the material.
System Analysis and Control of the Influence of a Mixed Type of Chemical Bond in Substances and Materials on their Structure and Properties
Authors: Sirotkin O.S. , Sirotkin R.O. , Perukhin M.Yu.
Published: May 2021

Nowadays, a lot of information on structure and properties of a wide variety of substances and materials has been accumulated. Yet, there is a lack of systemic universal approaches to assessing their structure and properties, including developing the effective approaches for monitoring and analysing various materials. It is of special interest in this respect to assess the effects of the chemical bond type on structure and properties of substances and materials. However, searching for necessary data on the effects of chemical bonds on structure of substances and materials is a rather laborious process. The authors, relying on the intermediate nature of chemical bonds of compounds of elements in any metallic and non-metallic material, as well as the system of chemical bonds and compounds developed by them in the form of a “Chemical Triangle”, produced an algorithm for creating a computer programme. It implies systematising of the database on the effect of chemical bond type on its length and energy, structure and various physicochemical and mechanical properties of homo-and heteronuclear compounds and materials. Development of such a specialised computer programme greatly simplifies this process, providing more efficient analysis and control of materials.

Authors: Tantia Mridul , Suryawanshi Pravin R. , Gupta Akshi , Rachakatla Praveen
Published: May 2021

Glomus tumours (GTs) are rare, mesenchymal neoplasms arising from the glomus body. Atypical sites, like the stomach, have been reported with extreme rarity since the usual location lies under the nail beds. We report a rare case of gastric GT in a 28-year-old female presenting with upper abdominal pain, intermittent haematemesis and melena. Contrast-enhanced computed tomography indicated a well-defined, heterogeneously enhancing lesion in the antral region of the stomach and a possibility of gastrointestinal (GI) stromal tumour (GIST). Upper GI endoscopy showed a wide-based lesion in the sub-mucosal plane with ulcerated mucosa. Laparoscopic excision of the tumour with primary closure of the defect was performed, with an uneventful post-operative course. Histopathological and immunohistochemical findings confirmed a gastric GT. Follow-up clinical and endoscopic examinations were normal. Gastric GTs should be a rare differential in patients with suspected GIST and upper GI bleed.
Models of true arithmetic are integer parts of models of real exponentation
Authors: Carl Merlin , Krapp Lothar Sebastian
Published: May 2021

Exploring further the connection between exponentiation on real closed fields and the existence of an integer part modelling strong fragments of arithmetic, we demonstrate that each model of true arithmetic is an integer part of an exponential real closed field that is elementarily equivalent to the real numbers with exponentiation and that each model of Peano arithmetic is an integer part of a real closed field that admits an isomorphism between its ordered additive and its ordered multiplicative group of positive elements. Under the assumption of Schanuel’s Conjecture, we obtain further strengthenings for the last statement.
Equidistribution on Kuga–Sato varieties of torsion points on CM elliptic curves
Authors: Khayutin Ilya
Published: May 2021

A connected Kuga–Sato variety

\mathbf{W}^r

parametrizes tuples of

r

points on elliptic curves (with level structure). A special point of

\mathbf{W}^r

is a tuple of torsion points on a CM elliptic curve. A sequence of special points is strict if any CM elliptic curve appears at most finitely many times and no relation between the points in the tuple is satisfied infinitely often. The genus orbit of a special point is the

\mathrm{Gal}(\bar{\mathbb{Q}}/\mathbb{Q}^{\mathrm{ab}})

-orbit. We show that genus orbits of special points in a strict sequence equidistribute in

\mathbf{W}^r(\mathbb{C})

, assuming a congruence condition at two fixed primes. A genus orbit can be very sparse in the full Galois orbit. In particular, the number of torsion points on each elliptic curve in a genus orbit is not bounded below by the torsion order. A genus orbit corresponds to a toral packet in an extension of

\mathbf{SL}_2

by a vector representation. These packets also arise in the study by Aka, Einsiedler and Shapira of grids orthogonal to lattice points on the 2-sphere. As an application we establish their joint equidistribution assuming two split primes.

Authors: Bobic S. , van Drunen C.M. , Callebaut I. , Hox V. , Jorissen M. , Fokkens W.J. , Hellings P.W.
Published: May 2021

BACKGROUND: Human nasal epithelial cells (hNECs) are the first line of immune defense and are able to produce mediators that recruit, activate and prolong survival of immune cells, among which IL-8 takes an important place. Studies on IL-8 and effects of dexamethasone on hNECs have been hampered by methodological shortcomings. The purpose of the study is to investigate the contribution of freshly isolated hNECs to IL-8 production in chronic rhinosinusitis with nasal polyps (CRSwithNP). Secondly, the effects of dexamethasone treatment on hNEC apoptosis and IL-8 production are investigated. METHODOLOGY: hNECs were freshly isolated from nasal polyp tissue and healthy inferior turbinate of NP patients (n=12) and from inferior turbinates of healthy donors (n=19) by protease treatment and two negative selection procedures. hNECs were incubated with IL-1β (10ng/ml), TNFα (10ng/ml) or dexamethasone (10, 100 and 1000 Amicrog/ml). After 24h, IL-8 levels were determined in the supernatants by ELISA. Finally, hNECs were incubated with increasing doses of dexamethasone and stained with trypan-blue and annexin-FITC/PI to study apoptosis. RESULTS: hNECs isolated from nasal turbinates of healthy and NP patients and polyp tissue from NP patients produced similar levels of IL-8. IL-1β induced higher levels of IL-8 production in all types of hNECs without differences between control and NP tissue. Dexamethasone induced apoptosis of hNECs concomitant with abrogation of IL-8 production by hNECs. CONCLUSIONS: IL-8 production by human nasal epithelial cells does not differ between NP and healthy tissue under baseline nor stimulatory conditions. Dexamethasone induces apoptosis of hNECs and abrogates IL-8 production.

Authors: Laudien M. , Dressel S. , Harder J. , Glaser R.
Published: May 2021

OBJECTIVE: The intact nasal barrier is a prerequisite for a functioning defense of the upper airway system, in particular the permanent threat by inhaled potentially harmful microorganisms. Antimicrobial peptides (AMP) play an important role in maintaining barrier function. There is few data about AMP in respect of nasal mucosa. This study is addressed to gain further insight into the differential AMP expression and secretion pattern according to defined anatomical regions of the vestibulum nasi and turbinates. PATIENTS AND METHODS: ELISA was applied to quantify concentrations of AMP RNase-7, psoriasin, hBD-2, hBD-3 and LL-37 in nasal secretions of 20 healthy volunteers. Immunohistochemistry was used to detect the local cellular sources of AMP in the vestibulum nasi (squamous epithelium) and compared to the mucosa of the turbinates (pseudostratified epithelium) in 10 healthy volunteers. RESULTS: Expression of RNase 7 and psoriasin was detected in all nasal secretion specimens, whereas LL-37 was detected in 16, hBD-2 in 5 and hBD-3 in 6 specimens. In the vestibulum nasi, luminal cell layers were demonstrated as local cellular sources for hBD-3 and RNase 7, whereas psoriasin was found in all layers of the stratified squamous epithelium. LL-37 was detected in 1 stroma cells sample, whereas hBD-2 was not detected at all. In turbinate biopsie,s hBD-3 and LL-37 were detectable in the epithelium, stroma cells and submucosal glands. RNase 7 was only present in submucosal glands. HBD-2 and psoriasin were not detected. CONCLUSION: These data demonstrate that the nasal epithelium contains a chemical defense shield through the expression and secretion of various AMP.

Authors: Bizzoni A. , Bolzoni Villaret A. , Lombardi D. , Tomenzoli D. , Danzi P. , Semeraro F. , Farina D. , Nicolai P.
Published: May 2021

We present a retrospective series of 11 patients treated for isolated sphenoid inflammatory disease (ISID) with visual impairment in the period between 1994 and 2008. The series included 7 females and 4 males. All patients, preoperatively assessed by CT or MR, underwent endoscopic sinus surgery and broad-spectrum antibiotic therapy. The procedure was always performed in an emergency setting, with an interval from the onset of visual impairment ranging between 1 and 40 days (mean 9 days). The possibility of recovery was related to both the modality of onset and severity of the deficit. All patients with reduction of the visual field reported significant improvement after surgery. Patients with decreased visual acuity obtained partial or complete resolution, while in patients with preoperative blindness no improvement was observed. Moreover, no postoperative improvement was noticed in the case of severe deficits with sudden onset, whereas the treatment of mild deficits was successful even some weeks after their occurrence. In conclusion, although some factors may predict the likelihood of recovery, any patient with ISID associated with visual impairment should receive immediate medical and surgical treatment. Endoscopic surgery should be considered the technique of choice.

Authors: Kurschel S. , Gellner V. , Clarici G. , Braun H. , Stammberger H. , Mokry M.
Published: May 2021

OBJECTIVE: Since endoscopic endonasal transsphenoidal surgery requires skills of both neurosurgeons and otorhinolaryngologists, and the nose is the primary corridor of approach, we favour the term `endoscopic rhino-neurosurgery` and report on our interdisciplinary experience treating non-adenomatous lesions with skull base extension. METHODS: Between 2004 and 2009, 58 patients with 21 different disease patterns underwent endoscopic rhino-neurosurgical procedures. Mean age was 39.9 years, 50% were female. Seven had undergone prior surgery. Clinically, 34.5% presented with visual field deficits and with nerve palsies. Preoperatively, 62.1% showed a normal pituitary function. RESULTS: Mean follow-up was 13.1 months. The surgical goal depended on type of lesion; the intended extent of resection was achieved in 81%. Recovery from visual field deficits occurred in 80%. Neither deteriorated nor new cranial nerve palsies were observed. A normal endocrinological function could be maintained in 94.4%. Permanent diabetes insipidus occurred in 7 patients. Surgical complications included cerebrospinal fluid (CSF) leaks in 6 patients and meningitis in 4. All complications were managed successfully. There was no surgery-related mortality. CONCLUSION: The endoscopic rhino-neurosurgical approach is applicable for a wide variety of lesions comprising sella and skull base. As our data prove, this technique can be performed with satisfying results in non-adenomatous lesions as well.

Authors: Myller J. , Dastidar P. , Torkkeli T. , Rautiainen M. , Toppila-Salmi S.
Published: May 2021

Endoscopic sinus surgery (ESS) is the main surgical approach in the treatment of chronic rhinosinusitis (CRS) after failure of medical treatment. ESS is based on the theory that obstruction of the maxillary sinus ostium is mainly behind the pathogenesis of CRS. Controversy remains concerning the enlargement of the natural maxillary sinus ostium. The aim of this study was to compare computed tomography (CT) findings after preservation or enlargement of the maxillary sinus ostium. Thirty patients with non-polypous CRS underwent randomized endoscopic sinus surgery with uncinectomy on one side and additional middle meatal antrostomy on the other side. Lund-Mackay (LM) scores and the ostium diameters were analysed from CT scans taken preoperatively and nine months postoperatively, and were used for comparison of the two operative techniques. In addition, the correlation between CT findings and subjective outcomes was studied. Comparison of the preoperative and postoperative CT scans revealed that significant reduction of LM score was achieved on both sides, regardless of the type of procedure performed. The postoperative area of the ostium remained significantly larger on the antrostomy side compared to the uncinectomy side. A large maxillary sinus ostium size seems to associate with lower postoperative LM score, but does not seem to provide superior symptom relief.

Published: May 2021

OBJECTIVES: The aim of our study was to measure CCL24 (eotaxin-2) levels in nasal lavage fluid of patients with different forms of sinonasal chronic eosinophilic inflammation to verify the relationship with nasal hypereosinophilia and symptoms. METHODS: Patients with nasal hypereosinophilia were randomly recruited and grouped in persistent allergic rhinitis, non-allergic rhinitis with eosinophilia syndrome (NARES) and chronic rhinosinusitis with polyps. Non rhinitic volunteers were recruited as controls. CCL24 concentration was measured by `Quantikine Human CCL24 Immunoassay`. Differential cell counts were performed by microscopic cytological examination of nasal tissue scraped by inferior turbinate. RESULTS: CCL24 levels measured in patient groups were significantly higher compared to control group with the highest levels in NARES patients. Eotaxin- 2 levels were significantly correlated to severity of symptoms and to the percentage of eosinophils in nasal tissue. CONCLUSIONS: We revealed high levels of CCL24 in all patient groups showing a significant correlation with the degree of eosinophilia and clinical symptoms. A prolonged accumulation of CCL24 inside the nasal mucosa may sustain the process of unspecific self-perpetuating eosinophil recruitment pathognomonic of these patients.
Using dynamic analysis of Laser-Doppler blood flowmetry to measure nasal mucosa bloody flow in postural changes
Authors: Tsai K.-K. , Yen C.-F. , Chu Y.-H. , Wang H.-W.
Published: May 2021

BACKGROUND: The regulation of nasal mucosa blood flow (NMBF) is affected by multiple factors, such as the autonomic nervous system, medications, temperature, humidity, endocrine, even emotional stress and vision. The effects of postural changes on NMBF have been described in numerous studies. However, the results are far from consistent due to different experimental designs. OBJECTIVE: Dynamic analysis of Laser-Doppler blood flowmetry (LDBF) is employed to recognize the effect of postural changes on NMBF. METHODS: NMBF was continuously measured by LDBF in 14 participants with changing postures (sitting and supine). NMBF was measured in Blood Perfusion Unit (BPU), equivalent to the number of red blood cells multiplied by their mean velocity in a measured volume. RESULTS: NMBF increases significantly in a supine posture compared with that in a sitting posture. CONCLUSION: Our study demonstrates that NMBF is significantly influenced after initial postural change, suggesting that changes in posture may be regarded as an important factor regulating NMBF.

Published: May 2021

Purpose: To study the role of heart and neural crest derivatives expressed 1 (HAND1) and cystathionine-beta-synthase (CBS) in the maintenance of cardiac architecture following high fat dietinduced obesity.

Methods: Mouse models of initial and critical heart disease were established by continuous feeding of high fat diet for 7 and 12 months, respectively. The expression of HAND1 and CBS were assayed using immunohistochemistry and Western blotting.

Results: Obesity led to mild and severe forms of heart disease which were confirmed through histological imaging. Initial obesity resulted in cardiac tissue remodeling along with initial degeneration, while critical obesity resulted in tissue hardening. The expression of HAND1 was upregulated 4.3 folds in the mild form of cardiac failure, relative to marginal expression pattern of HAND1 in control tissue. However, as the disease progressed, the expression of HAND1 was limited in serve form of cardiac failure. Moreover, the expression of cystathionine beta-synthase (CBS) was upregulated 3.7-fold in the initial form of heart failure, but was subsequently reduced in serve form of heart disease.

Conclusion: These results reveal that in high fat diet-induced cardiac stress, the over-expressions of HAND1 and CBS at the initial stages induce extensive alterations in cardiac architecture.

Purpose: To investigate in vitro antioxidant and anti-diabetic potentials of Fagonia indica Burm.f. Var. indica in order to provide scientific evidence for its traditional use.

Methods: Cold maceration method was employed for the preparation of extracts of aerial parts of the plant using chloroform, n-hexane, methanol and water as solvents. Total flavonoid and polyphenolic content of various extracts were determined by standard methods. The antioxidant and anti-diabetic activities of the extracts were determined using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and in vitro αglucosidase (maltase) inhibitory assays, respectively.

Results: Preliminary results indicated the presence of various phytochemicals in the extracts. The chloroform extract exhibited the highest contents of total flavonoids (65.98 ± 1.63 mg QE/g) and polyphenols (26.75 ± 1.09 mg GAE/g). This extract also showed the highest free radical scavenging (64.74 ± 1.43 %) with IC50 value of 34.18 ± 5.57 µg/mL while the methanol extract exerted the highest αglucosidase (maltase) inhibitory activity (45.22 ± 0.46 %) with half-maximal concentration (IC50) of 220.4 ± 0.41 µg/mL.

Conclusion: The extracts of the aerial parts of Fagonia indica possess significant anti-diabetic and antioxidant effect, thus justifying the traditional use of the plant for treatment of diabetes.

Published: May 2021

Purpose: To investigate the effect of temozolomide (TMZ) combined with radiotherapy (RT) on O-6- methylguanine-DNA methyltransferase (MGMT) protein and survival of recurrent malignant glioma patients.

Methods: Ninety-two patients with malignant glioma in our hospital from January 2014 to January 2015 were assigned to study and control groups using the random table method. Subjects in the control group received radiotherapy (total dose in the range of 60 – 75 Gy), while those in the study group were given TMZ orally (75 mg/m2) daily in addition to radiotherapy, as well as TMZ at 150 – 200 mg/m2. After treatment, clinical effectiveness was compared for the two groups. Changes in methylation of MGMT gene were determined in the two groups. The patients were followed up for 3 years, and the degrees of survival and recurrence were recorded.

Results: Total effectiveness of clinical treatment was markedly higher in the study group (76.09 %) than in the control group (45.65 %; p < 0.05). One month after radiotherapy, significant decrease in MGMT gene methylation was seen in patients in the study group, relative to control patients (p < 0.05). Patients in the study group had lower median recurrence but higher degree of survival in the 2nd and 3rd years, relative to control patients (p < 0.05).

Conclusion: The combination of temozolomide and radiotherapy is more effective than radiotherapy in the treatment of recurrent malignant glioma. The combined treatment significantly inhibits tumor recurrence in patients, and improves their prognosis and standard of life.

Published: May 2021

In humans, cognitive functions are controlled by the central nervous system, which is controlled by the brain. Any damage to the neuronal system causes serious impairment to the host as it may lead to neurodegenerative diseases like Parkinson’s, Alzheimer’s, autism and epilepsy. The physical and mental health of an individual is associated with food habits and brain health. The hypothalamus is the region of the brain that initiates a response to different types of stress. However, recent findings have revealed that food play a major role in regulating stress and mental health. In this regard, probiotics are beneficial microbes that are claimed to offer health benefits when consumed in adequate quantities. Probiotics alter the gut microbial composition in a positive way. Several in vitro, in vivo and pre-clinical studies have been conducted to determine the effects of probiotics or probiotic based food supplementation on the cognitive function of model system and human volunteers. Most of the studies suggest that the consumption of probiotic formulations improves cognitive function, stress management, and decision-making. This paper reviews recent findings regarding the influence of probiotic supplementation on cognitive function, especially in human subjects. The role of probiotics in maintaining healthy gut microbiota and detailed outcomes of clinical trials are here reported for easy understanding of the concept. However, more studies involving clinical trials are still required in the field of probiotics and cognitive function.
Military History and Strategic Studies as Imperatives for National Security Development in Nigeria
Authors: Wambu Chiemela Godwin , Ehimatie Amaechi
Published: May 2021

Nigerian military history is an aspect of Nigerian history that reconstructs the philosophies, beliefs, life and times of military personnel in relation to time and place. On the other hand, strategic studies involve a study of the security policies and political conduct of states in their interaction within the international system. Since it is the military institution that implements these security policies, itself central to the objectives of states in international politics, it is logical  to view military history and strategic studies as pivotal to the securitydevelopment of the Nigerian nation as it is for every other nation. Given this understanding, this study attempts to situate Nigerian military history and strategic studies as imperatives for national security development in Nigeria. To achieve its goal, the paper employs mostly secondary and but a few primary sources subjected to content historical analysis from which it was deduced that military history and strategic studies are important for the advancement of security development in Nigeria.

National Security and Wealth Creation: The Nigerian Sustainable Growth Nightmare
Authors: Azu Benedict , Uduh Dominic Mario , Mobosi Andrew I.
Published: May 2021

Insecurity has been one of the many challenges implicated as the biggest developmental and growth obstacle facing Nigeria as a nation. Since the independent in 1960, the country developmental strides have been hampered by one form of insecurity or the other. The country over the decades has experienced high rate of poverty, youth unemployment, widening income disparity, clashes and conflict, and violence among others with over 70% of her population living below poverty line. Security is undoubtedly the pillar upon which  every meaningful development could be achieved and sustained. Lend credence to this assertion, most advanced nations of the world place  high premium on security. Whilst Nigeria is richly blessed with abundant natural resources and human capital, negligence to numerous challenges of insecurity of the environment appears to have created porous security condition that engendered violence and retards growth and development. This paper is designed to empirically establish the nexus between national security and wealth creation in Nigeria. It also estimates the effect of national security on sustainable growth in Nigeria. Noting that insecurity affect growth with time lag, an Autoregressive Distributed Lag (ARDL) Model is built for the analysis. It is expected that security exacts positive time lag effects on growth, whilst insecurity negates sustainable growth.

Published: May 2021

The development of Web 2.0 technologies has led to the expansion of new technologies and services such as social media, which has become a new tool for public participation and alternative service delivery based on higher G2C (government to citizens) responsiveness. This ongoing development has caused governments to face expectations to adapt their communication channels to the changing environment of online social interactions. The main purpose of this paper is to investigate how local governments in the Czech Republic use social media in their communications with the public and the effects of these communications. To do so, this paper presents a comprehensive analysis of the Facebook communications of Czech regional capitals using multiple methodological approaches, including a survey, statistical analysis and an OLS model. The Facebook social networking site was chosen for this research because of its prevalent popularity over all relevant social media and the frequency of use in the Czech Republic both in general and by local governments, and because of its higher complexity of G2C interactions. The outcomes are given in the context of the relevant previous research.
The Importance of Applying Lean Innovation for Enhancing Harmonization of Customs Procedures in context of Digitalization of Customs Administration – A Case Study of Serbia
Authors: Dalton Sanja , Stosić Biljana
Published: May 2021

As a part of the Strategy for modernization, customs administrations face a need for the introduction of new communication information technologies (ICTs) that builds on a long and successful European history on technology and innovation. Hence, apart from compliance of legislation that prescribes customs procedures, customs authorities face important decisions regarding design and implementation. In that context, this empirical research explores the extent to what digitalization of the Customs Administration of Serbia can improve the customs transit performances, in terms of enforcement of trading policy, without applying certain managerial tools, such as process thinking in lean innovation. The final data analysis of the research indicates that managing the organization through the functional units, rather than the processes, and without applying lean principles to the digital transformation initiative would not completely standardize the customs transit procedure.

O objetivo deste artigo é discutir, a partir do cinema hollywoodiano, as visões distópicas sobre o futuro, tomando como base o imaginário sobre o fim do mundo a partir da perspectiva de crise ambiental oriunda na segunda metade do século XX. A crise ambiental demonstra que os efeitos da ação humana, sob a égide do sistema capitalista, não apenas promoverão o esgotamento dos recursos naturais, como a transformação radical do clima, especialmente o aquecimento global, tornando o planeta inabitável para todas as espécies. Diversos filmes do gênero ficção científica trouxeram direta ou indiretamente em seus enredos a discussão da degradação ambiental e suas consequências para a humanidade. Nossa discussão se dará a partir de três filmes: 2012 (2009), Elysium (2013) e Interstellar (2014), obras cinematográficas representativas do argumento defendido, ou seja, a relação entre ficção científica, cinema e meio ambiente.

Verbesserung von Konjunkturprognosen mittels des OECD Composite Leading Indicators und den Ergebnissen der ifo World Economic Survey - eine empirische Untersuchung für die G7-Staaten
Authors: Scheier Johannes
Published: May 2021

An Konjunkturprognosen werden die verschiedensten Forderungen gestellt. Die Hauptforderung ist zunächst einmal eine gute Qualität, damit Sie als Planungsgrundlage für Staaten, Unternehmen und Akteure an den Finanzmärkten dienen können. Der Fokus liegt bei dieser Untersuchung auf Frühindikatoren mit einem hohen qualitativen Anteil. Einen frühen Hinweis auf ihren Nutzen liefert Kirchgässner (1982), der die Ergebnisse der Neujahrsumfrage des Allensbach-Instituts für die Wirtschaftsentwicklung in Deutschland mit der Konjunkturprognose des Sachverständigenrats der Bundesregierung vergleicht. Die Umfrageergebnisse weisen dabei einen stärkeren Zusammenhang zur Wirtschaftsentwicklung des Folgejahres auf als die professionellen Konjunkturprognosen. Der Nutzen qualitativer Frühindikatoren wird vor allem für die rechtzeitige Erkennung konjunktureller Wendepunkte immer wieder festgestellt (Fritsche 1999, Hüfner / Schröder 2002, Kunkel 2003, Abberger / Nierhaus 2007, Seiler 2009, Ziegler 2009). Claveria, Pons und Ramos (2007) testen die Verwendung solcher Indikatoren in ökonometrischen Prognosemodellen. Ein Vergleich mit tatsächlich abgegebenen Konjunkturprognosen für die Wirtschaftsentwicklung auf Jahresbasis liegt jedoch nicht vor. Ein solcher Vergleich erfolgt in dieser Studie mittels zweier Datenreihen, die auf ihre Relevanz für die Konjunkturprognosen hin untersucht werden. Zum einen erfolgt eine Betrachtung des monatlich von der OECD veröffentlichten Composite Leading Indicators (CLI). Dieser wird für jede Volkswirtschaft individuell konstruiert und beinhaltet sowohl quantitative als auch qualitative Frühindikatoren. Zum anderen erfolgt eine Überprüfung einer weltweiten Umfrage des Münchener ifo-Instituts, der World Economic Survey (WES). Dabei werden weltweit Wirtschaftsexperten unter anderem hinsichtlich ihrer Einschätzung zur Lage der Weltkonjunktur in den nächsten 6 Monaten befragt. Stellvertretend für die Konjunkturprognosen werden Konsensprognosen der britischen Fachzeitschrift Consensus Forecasts als Datenbasis verwendet. Ihre Veröffentlichung erfolgt monatlich, wobei sich je eine Prognose auf das laufende und eine auf das kommende Jahr bezieht. Für jedes Jahr liegen also 24 separate Prognosen vor. Die Untersuchung erstreckt sich auf den Zeitraum 1991 – 2009 und umfasst die G7-Staaten. Der 2. Abschnitt dieser Untersuchung dient der Beurteilung der Qualität der untersuchten Konjunkturprognosen. Im 3. Abschnitt erfolgt ein Vergleich des Zukunftsbezugs der Prognosen mit den Zeitreihen der OECD und des ifoInstituts. Der 4. Abschnitt zeigt schließlich, dass die Berücksichtigung dieser Zusatzinformationen mit hoher Wahrscheinlichkeit zu einer Verbesserung der Konjunkturprognosen beigetragen hätte.
