The Svensson versus McCallum and Nelson Controversy Revisited in the BMW Framework: A Clarification
Authors: Bofinger Peter , Mayer Eric 
Published: April 2016

Zusammenfassung
Svensson auf der einen und McCallum und Nelson auf der anderen Seite haben in einer Reihe von Beiträgen kontrovers diskutiert, an welcher geldpolitischer Regel sich eine Notenbank orientieren sollte (vgl. Svensson, L., 2003a, 2003b, 2005, Svensson L., u. Woodford, M. 2005). Hierbei plädiert Svensson für so genannte Targeting Regeln. Allgemein kann man diese definieren als Reaktionsfunktion der Notenbank, die eine Regel in den Zielvariablen der Geldpolitik (Inflationslücke und Outputlücke) definiert und unmittelbar aus dem Optimierungsproblem ableitbar ist; sie stellt sozusagen eine Bedingung erster Ordnung dar. McCallum und Nelson hingegen befürworten die Orientierung an einfachen Regeln, die sich an wenigen, beobachtbaren makroökonomischen Zielgrößen orientieren und nicht fein abgestimmt sind auf eine konkrete Zielfunktion oder aber ein Modell. McCallum und Nelson haben im Rahmen dieser Debatte hybride eine Regel vorgeschlagen, die als Spezialfall sowohl eine einfache Regel wie die Taylor Regel (Taylor, J. 1993) als auch die optimale Regel beinhaltet. Im Rahmen unseres Beitrages haben wir analytisch und grafisch nachgewiesen, dass im Grenzfall die Regel von McCallum und Nelson und die optimale Targeting Regel von Svensson identische Politikergebnisse liefern und somit je nach Kalibrierung kein Unterschied zwischen beiden Regeln besteht. Svensson argumentiert im Rahmen der Debatte, dass insbesondere die Existenz von verrauscht gemessenen Daten die Regel von McCallum und Nelson obsolet werden lässt, da sie die Ökonomie einer enormen Zinsvolatilität aussetzen würde. Wir haben jedoch analytisch und grafisch dargestellt, dass gerade unter Datenunsicherheit die Regel von McCallum und Nelson unabhängig von der konkreten Kalibrierung bessere Politikergebnisse liefert als die Targeting Regel von Svensson. Als Ursache dafür, dass es uns gelungen ist, das Argument von Svensson zu widerlegen, ist anzuführen, dass die einfache Regel weniger aggressiv auf Datenänderungen reagiert als die optimale Regel. Reagiert die Notenbank nun aber fälschlicherweise auf verrauscht gemessene Daten, so entpuppt sich dieser Nachteil in normalen Zeiten als Vorteil in einem solchen Szenario. Die Zinsvolatilität einer Targeting Regel ist also höher als die unter einer einfachen Regel.
Internationaler Steuerwettbewerb um Direktinvestitionen bei überfüllbaren Infrastrukturgütern
Authors: Pauser Johannes , Nguyen Tristan 
Published: April 2016

SummaryIn this contribution, we analyze the provision of productive infrastructure goods (e. g. traffic facilities or results of scientific research) in the context of international tax competition for foreign direct investments (FDI). Mostly, these public inputs have two characteristics: on the one hand, firms who are unwilling to pay a user fee can be excluded. On the other hand, congestion externalities arise if many firms occupy the infrastructure good at the same time.We find out that local governments competing for international mobile capital should implement a user fee as an additional policy parameter in order to maintain efficiency. Otherwise, if local governments rely on a source-based tax on capital and a non-distortionary tax on local labour only, the decentralized equilibrium is socially inefficient. The derived condition for the optimal use of the available infrastructure is not fulfilled and firms will over-use the infrastructure. If, in addition, firms are charged a user fee, the decentralized equilibrium can be shown to be efficient. However, a selffinancing of infrastructure goods by user fees cannot be expected.
Hauptrefinanzierungszins, Interbankenmarkt und Geldangebot im Euroraum

Summary
In macroeconomic models, the nominal money supply, the long-term nominal interest rate, or even the inflation rate usually serves as the monetary policy variable. In practice, however, none of these variables is directly controlled by the central bank. Consequently, these models do not accurately reflect the implementation of monetary policy. Based on a theoretical model which incorporates the main institutional features of the euro area, this paper analyzes the transmission of monetary policy impulses from their implementation (setting the interest rate at which banks can obtain liquidity from the central bank) via the interbank market to the aggregate money and credit supply in an economy. Building on this analysis, we discuss the ability of the central bank to steer its operating target, the interbank market interest rate, and the money supply.
Anthropometric within-country Inequality and the Estimation of Skill Premia with Anthropometric Indicators
Authors: Baten Jörg , Blum Matthias 
Published: April 2016

Summary
We provide a literature review of anthropometric studies of within-country inequality. Then we discuss the relationship between skill premia and inequality indicators based on height variation. Skill premia describe the wage gap between an unskilled and a skilled building worker, while height CVs (coefficient of height variation) display the variance in net nutrition. We find that the two measures are correlated and that CV values are suitable to estimate skill premia. We supplement the existing literature by an additional tool, namely the estimation of skill premia based on the coefficient of height variation.

Published: April 2016

Abstract
The work presented in this paper addresses various techniques for automated preforming of profiles for structural components made from fiber-reinforced polymer composites. After reviewing the existing preforming techniques, a quantitative comparison with respect to two different application scenarios is presented. The technology comparison is conducted individually for the two application scenarios by means of a weighted decision matrix approach incorporating a list of technical and economic criteria. The preforming costs are derived by means of a bottom-up cost estimation model and are incorporated in the technology comparison.

Abstract
The aim of this study is to examine the technical quality of root canal fillings in an adult population in the Republic of Srpska, Bosnia and Herzegovina, who were treated in public dental institutions and private dental clinics.
Radiographs of faculty patients, aged 25-60 years old, who came for the first time were examined for the technical quality of root canal fillings. Patients with endodonticallytreated teeth were invited for an interview to reveal the providers of the endodontic treatment.
The percentages of teeth with adequate length (p<0.01) and taper (p<0.01) in institutions of public health cases were significantly greater than those in private clinic cases. In addition, the frequency of teeth with adequate root canal fillings in patients treated in public dental institutions was significantly greater than those treated in private dental clinics (p<0.01).
A significantly higher percentage of adequate canal fillings is present in teeth where endodontic treatment was performed in public dental institutions compared to private dental clinics. This result indicates the need to improve the quality of endodontic treatment through more intensive training for dentists in private practice.
Efficacy and Tolerability of a Fixed Combination of Perindopril/Amlodipine/Indapamide in Patients with Essential Hypertension: Pilot Study / Efikasnost I Tolerabilnost Fiksne Kombinacije Perindopril/Amlodipin/Indapimida Kod Pacijenata Sa Esencijalnom Hipertenzijom: Pilot Studija

Abstract
Hypertension is the major risk factor in Serbia and worldwide for the morbidity and mortality from cardiovascular and cerebrovascular diseases. A majority of patients need two or more antihypertensive drugs to adequately control blood pressure.
Our study group consisted of 12 patients with uncontrolled essential hypertension, without comorbidities, divided in two groups and followed for 12 weeks. The first group was treated with a single-pill of fixed-combination Perindopril 5 mg/Indapamide 1.25 mg and an additional tablet of Amlodipine 5 mg. The second group received a single-pill fixed-combination of Perindopril 5 mg/Indapamide 1.25 mg/Amlodipine 5 mg. Our research showed significant decreases in systolic (p=0,05) and diastolic (p<0,05) blood pressure in both groups after 12 weeks of treatment. The study also showed a higher percentage of patients who achieved the targeted blood pressure (< 140/90 mmHg) on the single-pill triple combination drug (69.7%) in comparison with the other group (50%). No adverse effects were recorded in both groups.
Our results revealed significant efficacy and tolerability of a single-pill triple-fixed combination Perindopril/Amlodipine/ Indapamide in patients with uncontrolled essential hypertension without comorbidities.

Abstract
The article analyses theoretical aspects of the qualitative assessment of logistics and transport specialists’ potential, as well as provides research results on competence and capacity-building process in preparation of logistics and transport specialists. The results enabled to identify problematic areas of graduate integration in the labour market and foresee the possible requirements for professional development. In some cases, internal motivation is related to problematic points or negative view from the environment, as well as poor understanding of knowledge benefits in the person’s practical life. Training and education is objectively at the meeting point between research, technological and organisational systems. In such conditions the objective of the education on logistics is to offer the customers the best possible service in the field of the transfer of knowledge in harmony with the trend in logistics programme development. The main problems and perspectives of logistics education and training process are discussed in this article.
Methods of Evaluating Transportation and Logistics Operations in Supply Chains
Authors: Lukinskiy Valery , Dobromirov Viktor 
Published: April 2016

Abstract
The paper considers some issues related to different approaches to estimation of transport and logistic(s) operations in supply networks; analysis is made of the methods and models of analytical description of those operations; it is shown that the works under consideration have no single approach to their accounting, which makes it impossible to form a model of a simple logistic network including such basic operations as transportation and storage; based on the classical model of Harris-Wilson, six versions have been obtained for a simple supply network showing, in particular, value added to the product price stemming from the previously performed logistic operations as well as restrictions associated with the load capacity (cargo capacity) of the vehicle. The choice of an optimum version of the supply network is made based on the criterion of minimum total costs; there are supplied the examples of calculations for different versions of the developed models enabling estimation of the influence of transport and logistic operations on the efficiency of the supply network.
Interaction between Interfacial Collinear Griffith Cracks in Composite Media under Thermal Loading
Authors: Mishra P.K. , Das S. 
Published: April 2016

AbstractThis article deals with the interactions between a central crack and a pair of outer cracks situated at the interface of orthotropic elastic half planes under thermo-mechanical loading. The mixed boundary value problem has been reduced to a pair of singular integral equations which has been solved numerically using Jacobi polynomial method. The interaction effects have been obtained in terms of stress magnification factors depending on the crack spacing and crack length. The phenomena of crack shielding and crack amplification have been depicted through graphs for different particular cases.
The Integrability of an Extended Fifth-Order KdV Equation in 2+1 Dimensions: Painlevé Property, Lax Pair, Conservation Laws, and Soliton Interactions
Authors: Xu Gui-qiong , Deng Shu-fang 
Published: April 2016

Abstract
In this article, we apply the singularity structure analysis to test an extended 2+1-dimensional fifth-order KdV equation for integrability. It is proven that the generalized equation passes the Painlevé test for integrability only in three distinct cases. Two of those cases are in agreement with the known results, and a new integrable equation is first given. Then, for the new integrable equation, we employ the Bell polynomial method to construct its bilinear forms, bilinear Bäcklund transformation, Lax pair, and infinite conversation laws systematically. The N-soliton solutions of this new integrable equation are derived, and the propagations and collisions of multiple solitons are shown by graphs.

Abstract
Tanaka, H, Ikezoe, T, Umehara, J, Nakamura, M, Umegaki, H, Kobayashi, T, Nishishita, S, Fujita, K, Araki, K, and Ichihashi, N. Influences of fascicle length during isometric training on improvement of muscle strength. J Strength Cond Res 30(11): 3249–3255, 2016—This study investigated whether low-intensity isometric training would elicit a greater improvement in maximum voluntary contraction (MVC) at the same fascicle length, rather than the joint angle, adopted during training. Sixteen healthy women (21.8 ± 1.5 years) were randomly divided into an intervention group and a control group. Before (Pre) and after (Post) training, isometric plantarflexion MVCs were measured every 10° through the range of ankle joint position from 20° dorsiflexion to 30° plantarflexion (i.e., 6 ankle angles). Medial gastrocnemius fascicle length was also measured at each position, using B-mode ultrasound under 3 conditions of muscle activation: at rest, 30%MVC at respective angles, and MVC. Plantarflexion resistance training at an angle of 20° plantarflexion was performed 3 days a week for 4 weeks at 30%MVC using 3 sets of twenty 3-second isometric contractions. Maximum voluntary contraction in the intervention group increased at 0 and 10° plantarflexion (0°; Pre: 81.2 ± 26.5 N·m, Post: 105.0 ± 21.6 N·m, 10°; Pre: 63.0 ± 23.6 N·m, Post: 81.3 ± 20.3 N·m), which was not the angle used in training (20°). However, the fascicle length adopted in training at 20° plantarflexion and 30%MVC was similar to the value at 0 or 10° plantarflexion at MVC. Low-intensity isometric training at a shortened muscle length may be effective for improving MVC at a lengthened muscle length because of specificity of the fascicle length than the joint angle.

Abstract
Johnston, MJ, Cook, CJ, Drake, D, Costley, L, Johnston, JP, and Kilduff, LP. The neuromuscular, biochemical, and endocrine responses to a single-session vs. double-session training day in elite athletes. J Strength Cond Res 30(11): 3098–3106, 2016—The aim of this study was to compare the acute neuromuscular, biochemical, and endocrine responses of a training day consisting of a speed session only with performing a speed-and-weights training session on the same day. Fifteen men who were academy-level rugby players completed 2 protocols in a randomized order. The speed-only protocol involved performing 6 maximal effort repetitions of 50-m running sprints with 5 minutes of recovery between each sprint, whereas the speed-and-weights protocol involved the same sprinting session but was followed 2 hours later by a lower-body weights session consisting of 4 sets of 5 backsquats and Romanian deadlift at 85% one repetition maximum. Testosterone, cortisol, creatine kinase, lactate, and perceived muscle soreness were determined immediately before, immediately after, 2 hours after, and 24 hours after both the protocols. Peak power, relative peak power, jump height, and average rate of force development were determined from a countermovement jump (CMJ) at the same time points. After 24-hours, muscle soreness was significantly higher after the speed-and-weights protocol compared with the speed-only protocol (effect size η2 = 0.253, F = 4.750, p ≤ 0.05). There was no significant difference between any of the CMJ variables at any of the posttraining time points. Likewise, creatine kinase, testosterone, and cortisol were unaffected by the addition of a weight-training session. These data indicate that the addition of a weight-training session 2 hours after a speed session, whereas increasing the perception of fatigue the next day does not result in a difference in endocrine response or in neuromuscular capability.

Abstract
Beyer, KS, Fukuda, DH, Redd, MJ, Stout, JR, and Hoffman, JR. Player selection bias in National Football League draftees. J Strength Cond Res 30(11): 2965–2971, 2016—Relative age effects (RAEs) have been studied as a potential factor associated with player selection bias in numerous sports. However, little research has examined the role of RAEs among National Football League (NFL) draftees. The purpose of the current study was to determine the existence of RAEs in NFL draftees from the last 10 NFL drafts. Draftee birth dates were collected and divided into calendar and scholastic quarters (SQ1–SQ4). To determine the presence of RAEs in specific subsets, NFL draftees were grouped according to round drafted, position, level of conference play, and age at the time of the draft. Significant χ2 tests (p ≤ 0.05) comparing observed birth-date distributions vs. the expected birth-date distribution from the general population were followed up by calculating the standardized residual for each quarter (z > ±2.0 indicating significance). Overall, no RAEs were seen when birth-date distribution was assessed using calendar quarters (p = 0.47), but more draftees were born in SQ2 (December–February) than expected (p < 0.01; z = +2.2). Significantly more draftees were born in SQ2 than expected for middle-round draftees (p = 0.01; z = +2.4), skill positions (p = 0.03; z = +2.3), Power Five college draftees (p < 0.01; z = +2.6), and early draftees (p < 0.01; z = +3.1). However, reverse RAEs were seen among late draftees, with fewer draftees being born in SQ2 (z = −3.6) and more being born in SQ4 (June–August; z = +2.6) than expected. In contrast to previous research, the current study observed significant RAEs in NFL draftees from the last 10 years. This player selection bias should be considered when evaluating long-term athlete development models in American football.

Abstract
Parsonage, JR, Secomb, JL, Tran, TT, Farley, ORL, Nimphius, S, Lundgren, L, and Sheppard, JM. Gender differences in physical performance characteristics of elite surfers. J Strength Cond Res 31(9): 2417–2422, 2017—The purpose of this study was to describe and compare the gender differences in physical performance characteristics of elite surfers. Twenty competitive female surfers (CFS) and 20 competitive male surfers (CMS) performed a battery of physical performance tests: squat jump (SJ), isometric midthigh pull (IMTP), 15-m sprint paddle, and 400-m endurance paddle during a single testing session. All performance measures were significantly different between CFS and CMS (p < 0.01). Specifically, CMS produced greater peak force production (28.5%) and jumped higher (27.7%) in the SJ and produced greater normalized peak force during the IMTP (18.9%) compared with CFS. For paddling performance, CMS were faster over 5, 10, and 15 m (12.4%, 9.7%, and 10.9%), possessed a higher peak paddling velocity (11.3%), and recorded faster paddle times over 400 m (11.8%). The results of this study suggest that CMS exhibit superior physical performance characteristics than CFS, in relation to both the lower and upper body. Strength and conditioning practitioners should therefore implement a structured and periodized program to facilitate strength qualities that underpin surfing performance for all participants, but as highlighted in the current investigation, female surfers may have a greater window for adaptation and therefore vast benefit of targeting their underdeveloped physical qualities.

Abstract
Read, P, Oliver, JL, Croix, MD, Myer, GD, and Lloyd, RS. Consistency of field-based measures of neuromuscular control using force-plate diagnostics in elite male youth soccer players. J Strength Cond Res 30(12): 3304–3311, 2016—Deficits in neuromuscular control during movement patterns such as landing are suggested pathomechanics that underlie sport-related injury. A common mode of assessment is measurement of landing forces during jumping tasks; however, these measures have been used less frequently in male youth soccer players, and reliability data are sparse. The aim of this study was to examine the reliability of a field-based neuromuscular control screening battery using force-plate diagnostics in this cohort. Twenty-six pre–peak height velocity (PHV) and 25 post-PHV elite male youth soccer players completed a drop vertical jump (DVJ), single-leg 75% horizontal hop and stick (75%HOP), and single-leg countermovement jump (SLCMJ). Measures of peak landing vertical ground reaction force (pVGRF), time to stabilization, time to pVGRF, and pVGRF asymmetry were recorded. A test-retest design was used, and reliability statistics included change in mean, intraclass correlation coefficient, and coefficient of variation (CV). No significant differences in mean score were reported for any of the assessed variables between test sessions. In both groups, pVGRF and asymmetry during the 75%HOP and SLCMJ demonstrated largely acceptable reliability (CV ≤ 10%). Greater variability was evident in DVJ pVGRF and all other assessed variables, across the 3 protocols (CV range = 13.8–49.7%). Intraclass correlation coefficient values ranged from small to large and were generally higher in the post-PHV players. The results of this study suggest that pVGRF and asymmetry can be reliably assessed using a 75%HOP and SLCMJ in this cohort. These measures could be used to support a screening battery for elite male youth soccer players and for test-retest comparison.
