Electronic Information Resource Optimisation in Academic Libraries: A Comparative Study on Licensing Provision of Commercial Publisher
Authors: Singh Arvind Kumar , Mukherjee Bhaskar
Published: June 2018

Electronic information resources are increasingly become an important component of the collection-building activities of libraries. This paper attempts to understand how far the licenses of commercial publishers support resource optimisation in general and what other important issues that are usually ignored by publishers, knowingly or unknowingly, but are essential for better resource optimisation. Five international publishers namely Elsevier, EBSCO, Sage, Springer, and Taylor & Francis were identified and analysed their agreements that are available in public domain with some model agreements like Liblicense model and model license developed by John Cox Associate. Study indicates that core part of the negotiations still remain price, IP access, display, ILL/document supply, etc. while important issues like perpetual access, archiving, self-archiving, copy of individual articles and share the same for non-commercial use by authorised users were minor issues of the contract. Furthermore, most of the obligations of the publishers that are identified as core issues in Liblicense model are also absent in commercial publishers’ license. A greater awareness of this to library managers is essential. They must be acquainted with the clause of the license agreement of commercial publishers and must negotiate to that extent so that the access should be uninterrupted.

Predatory Publishers using Spamming Strategies for Call for Papers and Review Requests : A Case Study
Authors: Petrisor Alexandru-Ionut
Published: June 2018

Spam e-mail and calls from the predatory publishers are very similar in purpose: they are deceptive and produce material losses. Moreover, the predatory publishers show evolving strategies to lure potential victims, as their number increases. In an effort to help researchers defending against their constant menace, this article aims to identify a set of common features of spam e-mail and calls from predatory publishers. The methodology consisted of a comparative analysis of data found on the Internet and e-mails received at several addresses during December 2017 – January 2018. The results indicate that concealed, fake or disguised identity of the sender and/or of the message, mass mailing, missing or useless opt-out option and an obvious commercial character are the most prominent common features. Moreover, the location of predatory publishers is well disguised; the analysis of the real location, found using web-based tools, suggests a joint management or at least a concerted action of several publishers, and raises additional questions related to the reasons of masking the true location. From a theoretical standpoint, the results show, once again, that predatory publishers are a part of the worldwide scam, and should be ‘convicted’ in a similar way, including the means of legal actions. From a practical perspective, distinct recommendations were phrased for researchers, policy makers, libraries, and future research.

Phytoremediation and Nanoremediation : Emerging Techniques for Treatment of Acid Mine Drainage Water
Authors: Das Pratyush Kumar
Published: June 2018

Drainage from mining sites containing sulfur bearing rocks is known as acid mine drainage (AMD). Acid mine drainage water is a serious environmental pollutant that has its effects on plants, animals and microflora of a region. Mine water drainage mainly occurs due to anthropogenic activities like mining that leave the sulfur bearing rocks exposed. This drainage water poses as a potent soil, water and ground water pollutant. Although a lot of remediation measures have been implemented in the past but, none of them have been able to solve the problem completely. This review intends to focus on new emerging and better techniques in the form of phytoremediation and nanoremediation for treatment of acid mine drainage water. Besides, the review also gives more importance to the phytoremediation technique over nanoremediation because of the cost effectiveness and eco-friendly nature of the first and the nascent status of the latter. A hypothetical model discussing the use of hyperaccumulator plants in remediation of acid mine water has been proposed. The model also proposes natural induction of the phytoremedial ability of the plants involved in the remediation process. The proposed model assisted by inputs from further research, may be helpful in proper treatment of acid mine drainage water in the near future.
Regulation of Food Intake : A Complex Process
Authors: Jain Swati , Singh Som Nath
Published: June 2018

Researchers have created a wealth of knowledge about the mechanisms that regulate food intake, appetite and therefore weight control. The control of appetite is a complex mechanism and involves the coordination of inputs from both physiological and environmental sources. Early theoretical approaches were based on the idea that the control mechanism was dedicated exclusively to signals from glucose metabolism, amino acids or proteins, or adipose tissue. However, a complex system of biologic and environmental factors regulates our appetite. The brain integrates chemical and nervous signals to control hunger and satiety. These controls include sensory and gastrointestinal signals, neurotransmitters and neuropeptides. This review paper summarizes the existing plethora of the highly convoluted process of appetite regulation and food intake.

Authors: Acharya Somen , Kumar Hitesh
Published: June 2018

A field experiment was conducted to investigate effects of four organic manure sources (vermicompost, poultry manure, sheep & goat manure and cattle FYM) on growth and yield attributing characters of garlic in greenhouse condition during extreme winter months (October to May) at Leh-Ladakh, India with three application rates of organic manures viz. 10, 20 and 30 tons ha-1.  The results revealed that, organic manure application enhanced plant growth, improved garlic yield and its components viz. no. of cloves per bulb, bulb diameter and weight. Also, with increasing rate of application of organic manures from 10 to 20 tons ha-1, all growth and yield characters of garlic were improved. Vermicompost and poultry manure had significant effects on plant growth characters viz. plant height, number of leaves per plant, length and width of leaves especially in the T3 and T6 treatments. Highest garlic yield (105.03q ha-1) was achieved in T6 treatment (poultry manure @ 20 tons ha-1). Overall, application of organic manures proved to be beneficial for garlic production and its application should be popularized for sustainable agriculture in fragile ecosystem of cold arid desert of Ladakh region.

Authors: Negi P. S. , Singh Ranjit , Dwivedi S. K.
Published: June 2018

Morphological and biochemical studies of Crataegus crenulata syn. Pyracantha crenulata fruits have been carried out and an herbal formulation was prepared from its fruit juice. The small sized berries weighing 250 mg each and 4000±32 fruits in 1kg weight contain 25% fruit juice. Biochemical analysis of fruit juice quantified flavonoides content (2-3%), Vitamin ‘A’ (289 IU/ 100g), vitamin B12 (110 µg/100g), Vitamin ‘C’ (57.8mg/100g), Vitamin ‘E’ (289mg/100g) protein (1.6%), calcium (3.79 mg/100g), magnesium (1.38 mg/100g), and potassium (1.39mg/100g). The present study was designed to investigate the efficacy of the herbal formulation from C. crenulata fruits in two forms of experimental hypertension: cadmium chloride induced and in normotensive control in animal module. Since the blood pressure fells down independently in the hypertensive and normotensive rats, the study strongly suggested C. crenulata possesses anti-hypertensive or hypotensive effects.

Authors: Hedayati Ehsan , Vahedi Mohammad
Published: June 2018

Performing various experimental, theoretical, and numerical investigations for better understanding of behavioural characteristics of metals under impact loading is of primary importance. In this paper, application of smoothed particle hydrodynamics (SPH) method in impact mechanics is discussed and effective parameters on impact strength of an aluminum plate are investigated. To evaluate the accuracy of smoothed particle hydrodynamics method for simulating impact, Recht and Ipson model is first provided thoroughly for both Rosenberg analytical model and smoothed particle hydrodynamics method, and then plots of initial velocity-residual velocity and initial velocity-absorbed energy for target of aluminum 6061-T651 are presented. The derived information and simulation results expresses that the maximum error percentage of smoothed particle hydrodynamics method in compared with Rosenberg analytical model is within an acceptable range. Therefore, the results of smoothed particle hydrodynamics method verify the Rosenberg analytical model with high accuracy. Results reveal that higher initial impact velocity decreases the time of projectile penetration, and so penetration depth and length as well as the local damage rate of plate increases.

Published: June 2018

In Aerospace applications, pressure measurement plays a vital role as it serves as one of the input to onboard controller to aid decision- making on initiating or terminating some of the critical events. In this paper, the design aspects of pressure sensor using linear eddy current displacement sensor (ECDS) are presented along with its performance evaluation. The static calibration is carried out to select the best position of ECDS in the proposed pressure sensor. The effect of target temperature on sensor output is presented with test results to aid compensation. A compensation algorithm is developed to minimise the error due to target temperature. The developed compensation algorithm is validated using thermal calibration. The designed pressure sensor is calibrated using Arson dynamic pressure calibrator to evaluate its bandwidth. The calibration results are analysed to aid future sensor design towards improvement of accuracy, bandwidth and miniaturisation.

A Triangular-shaped Quarter-mode Substrate Integrated Waveguide based Antenna for WBAN Applications
Authors: Chaturvedi Divya , Raghavan S.
Published: June 2018

In this study, a compact quarter-mode substrate integrated waveguide (QMSIW) based dual-band antenna is proposed for wireless body area network applications. A QMSIW resonator is realised by splitting the full-mode substrate integrated waveguide cavity along the perfect magnetic conductor walls. The proposed antenna preserves the fundamental mode TE110 and the third order mode TE220 of the square SIW cavity. The proposed antenna is linearly polarised in the lower band at 2.45 GHz and circularly polarised in the higher frequency band at 5.8 GHz. The on-body performance of the antenna is validated on a piece of pork muscle tissue and it has been found to be stable with respect to surroundings. The proposed antenna covers the ISM bands 44 MHz (2.445 GHz - 2.489 GHz) and 225 MHz (5.730 GHz - 5.955 GHz) at 2.45 GHz and 5.8 GHz, respectively. The measured gain of the antenna on pork tissue is 1.87 dBi and 5.5 dBi at two bands. In addition, the specific absorption rate is obtained of 0.65 mW/g and 1.51 mW/g at two bands (wext = 2 mm), averaged over 1 g of muscle with 100mW input power. Moreover, the simulated and experimental results demonstrate a good agreement.
Aerodynamic Parameters Estimation Using Radial Basis Function Neural Partial Differentiation Method
Authors: Sanwale Jitu , Singh Dhan Jeet
Published: June 2018

Aerodynamic parameter estimation involves modelling of force and moment coefficients and computation of stability and control derivatives from recorded flight data. This problem is extensively studied in the past using classical approaches such as output error, filter error and equation error methods. An alternative approach to these model based methods is the machine learning such as artificial neural network. In this paper, radial basis function neural network (RBF NN) is used to model the lateral-directional force and moment coefficients. The RBF NN is trained using k-means clustering algorithm for finding the centers of radial basis function and extended Kalman filter for obtaining the weights in the output layer. Then, a new method is proposed to obtain the stability and control derivatives. The first order partial differentiation is performed analytically on the radial basis function neural network approximated output. The stability and control derivatives are computed at each training data point, thus reducing the post training time and computational efforts compared to hitherto delta method and its variants. The efficacy of the identified model and proposed neural derivative method is demonstrated using real time flight data of ATTAS aircraft. The results from the proposed approach compare well with those from the other.

Authors: Mittal Gaurav , Pathak Nagendra Prasad
Published: June 2018

This paper presents the wideband bandpass filter (BPF) in the microwave frequency domain. The realisation approach is based on spoof surface plasmon polaritons (SSPPs) phenomenon using plasmonic metamaterial. A novel unit cell is designed for filter design using an LC resonator concept. Then SSPPs BPF is realised using an optimised mode converter and five unit cells. This paper includes a brief design detail of the proposed novel unit cell. The passband of BPF is achieved at approximately 1.20 - 5.80 GHz, 3dB bandwidth is tentatively 4.60 GHz and the insertion loss is less than 2 dB approximately over the passband. The overall dimension of fabricated filter is (90 x 45) mm. A basic schematic of transmission line representation is also proposed to evaluate the BPF structure.

Authors: Ramamurthy N. V. , Vinayagam B. K. , Roopchand J.
Published: June 2018

Military tracked vehicle and crew are modelled together in this paper as integrated man-machine lumped parameter model, by integrating the simplified 5 degrees of freedom (DoF) tracked vehicle model, including seat and 4 DoF human bio-dynamic model, thus resulting in a 9 DoF simplified vehicle-occupant model. Then the natural frequency of major mass segment namely the chassis mass is obtained through simulation study, for a known road input. The value obtained is compared with that of an earlier research work, for validation of said man-machine model. Then focusing our study locally at crew seat location, parameters of crew seat suspension for ride comfort are optimised using the optimal digital state space controller designed for this purpose by implementing it in a 2 DoF occupant - seat suspension model and its Simulink model constructed. Simulation results illustrate the attainment of the goal by meeting the controller design requirements.

Authors: Sudarsan N. V. , Sarsar R. B. , Das S. K. , Naik S. D.
Published: June 2018

Determination of short start pressure (SSP) for gun system has always been of paramount interest for gun designers. In this paper, a generalised model has been developed for theoretical prediction of SSP for rifled gun system using dimensional analysis approach. For this, parameters affecting the SSP of the gun like rifling dimensions, driving band dimensions, material properties of driving band, projectile mass and diameter are taken into consideration. For a particular case of large caliber rifled gun system, the model is established using linear relations among dimensionless groups of parameters. The model has been validated by data available from the open literature.
Spectroscopic Evaluation of Optical Parameters of a Transition Metal Salt Filled Polymer Material
Authors: Banerjee M. , Jain Amit , Mukherjee G. S.
Published: June 2018

Transition metal salt, manganese chloride was incorporated into polyvinyl alcohol (PVA) to prepare metal salt filled polymer material (M-PVA) and their optical properties were evaluated. XRD, UV-vis, and FTIR analyses reveal that there is strong interaction between PVA and the manganese chloride salt. From XRD analysis, the inter-chain separation in pristine PVA and M-PVA was found to be 5.62 Ǻ and 4.70 Ǻ, respectively; thus indicating that the packing of polymer chains is more compact under the influence of manganese chloride. Optical band gap of PVA was found as 5.06 eV but such band gap was reduced on incorporation of manganese chloride into the PVA matrix system with corresponding increase in optical conductivity. Spectral evaluation indicates that refractive index of M-PVA decreases faster than that of PVA in the visible range. Abbe Number was found to have decreased on incorporation of manganese chloride into the PVA matrix system indicating increase in optical dispersion in conformity with the trend of increase in dispersion energy (Ed). The average interband oscillator wavelength was found close to the respective values of absorption edges.

Shape cumulative charge is a set of explosive components that uses directional energy accumulation. The water cumulative charges are filled with water, which forms a water-directed beam that has the ability to effectively counteract the intense flame that is induced by gaseous flammable gas or liquid from the damaged gas duct and extinguishes it. Study contains description of the experimentally constructed cumulative charge as well as the analysis of results of experiments carried out in real conditions. Based on the facts gained from the experiments we can conclude that the cumulative water charge has a significant potential and possibilities to extinguish an intense flame.
Discourse Analysis of the Communicative Approaches Used by The Pre-service Teachers
Authors: Uçak Esra , Bağ Hüseyin
Published: June 2018

The
purpose of the study is to determine the communicative approach used by
pre-service teachers in science teaching. For this purpose, 7-week
instructional program was developed and applied to raise the pre-service
teachers’ awareness of dialogic teaching and communicative approach. Before and
after this instructional program, one lesson of each pre-service teacher was
video-recorded. These videos were analyzed on the basis of four classes of
communicative approach developed by Mortimer and Scott (2003). In line with the purpose of
the study, the discourse analysis method was employed to determine the
communicative approach used by the pre-service teachers. For this discourse analysis, the lessons of the pre-service teachers
were used as sample cases. Moreover, the pre-service teachers were asked to
watch their lessons video-recorded before and after the implementation of the
instructional program and to write which communicative approach they used in
these lessons and why they used this approach. The findings of the current
study revealed that the pre-service teachers mostly preferred the authoritative
approach before the instructional program; yet, after the instructional
program, besides the authoritative approach, they started to use dialogic interaction-based
communicative approach in their lessons. Their reasons for using this
communicative approach were also elicited.

Published: June 2018

Cowpea mild mottle virus (CPMMV) is one of important virus which infects soybean and become an endemic disease since the first time reported in Java and Sumatra. Research was conducted to study the host range of CPMMV and to evaluate response of new type soybean varieties to CPMMV specific isolate.  Host range study of CPMMV CR16 isolate was conducted by sap transmission method to 11 species of indicator plants, whereas evaluation of soybean response involved 10 varieties.  The resistance response of soybean variety was based on incubation period, and of either  the disease incidence or severity. Virus infection on test plants were confirmed by dot immunobinding assay (DIBA) using specific CPMMV antisera. The CPMMV CR16 isolate was able to infect systemically 8 plant species belongs to Leguminoceae, and Solancaeae; while the virus caused local infection on Amaranthaceae. All plant species infected systemically proved to become sources of inoculum for CPMMV when they used in back inoculation to soybean.  Response of soybean varieties to CPMMV CR16 isolate can be categorized into susceptible (Detam 1, Detam 2, Detam 3, Anjasmoro, Wilis), moderated (Detam 4, Malika, Dena 1) and resistant (Argomulyo and Grobogan).

The paper attempts to answer the question of what outcomes this challenge produces.
Budżet partycypacyjny jako nowa forma współdecydowania o finansach lokalnych
Authors: Rachwał Marcin
Published: June 2018

Jednym z pomysłów na szersze włączenie obywateli (mieszkańców) wspólnot lokalnych w życie polityczne jest idea budżetu partycypacyjnego. Wskazane rozwiązanie to oddolny proces określania priorytetów budżetowych i wskazywania przez obywateli, które inwestycje i projekty należy realizować w ich miejscowości. Po raz pierwszy budżet partycypacyjny został wprowadzony w mieście Porto Alegre (Brazylia) w 1989 roku. Tak więc jest to nowy projekt, który dość szybko został rozpowszechniony w innych wspólnotach lokalnych, przede wszystkim Ameryki Łacińskiej i Europy. Budżet partycypacyjny pokazuje konkretne możliwości stworzenia przestrzeni decyzyjnej dla zwykłych obywateli, którzy okazują się zdolni do zarządzania zasobami publicznymi. Warto również zwrócić uwagę na fakt, iż omawiane rozwiązanie skłania do wspólnotowego myślenia o społeczeństwie, gdyż nie ogranicza się do ustalenia przez każdego obywatela własnych potrzeb, lecz zmusza uczestników do rozważenia swoich postulatów w kontekście propozycji innych mieszkańców.
Mieszany system wyborczy w wersji „kombinacyjnej”, jako sposób wzmocnienia dużych partii politycznych na przykładzie Litwy
Authors: Jarentowski Marek
Published: June 2018

Na Litwie, pomijając pierwsze tranzycyjne wybory, w wyborach do Sejmu od 1992 r. stosuje się mieszany system wyborczy w odmianie zwanej kombinacją lub superpozycją. Połowa mandatów obsadzana jest wedle formuły większości bezwzględnej, a druga połowa wedle formuły proporcjonalnej. Wyborca ma dwa głosy. W opracowaniu opisano też inne elementy systemu wyborczego i ich ewolucję. Głównym jednak pytaniem w badaniu było to czy wyniki wyborów w puli proporcjonalnej wprowadzają do parlamentu więcej partii, niż wyniki wyborów z puli większościowej. Okazuje się, że więcej partii i mniejsze partie dostają się do Sejmu właśnie dzięki formule większościowej. Przeczy to powszechnej tezie o tym, że formuła większościowa przyczynia się do zmniejszenia rozdrobnienia parlamentu i ułatwia utworzenie większościowego rządu. Ponadto, z obliczeń wynika, że druga tura, stosowana w puli większościowej, w 75% okręgów i tak potwierdza zwycięstwo kandydata, który zajął pierwsze miejsce w pierwszej turze.
Odnajdywanie prostoty w złożoności. Wybrane zastosowania gier 2×2 w badaniach zjawisk politycznych
Authors: Wajzer Mateusz
Published: June 2018

W artykule poruszono problematykę wykorzystania gier 2×2 w badaniach zjawisk politycznych. Omówiono zarówno podstawowe zagadnienia teoretyczne, jak i przykładowe zastosowania. Wśród zagadnień teoretycznych wyróżniono: równowagę Nasha, optymalność w sensie Pareto oraz aksjomaty charakteryzujące schemat arbitrażowy Nasha. Przykłady użycia gier 2×2 w badaniach politologicznych zaprezentowano, stosując podział na gry o wypłatach symetrycznych i gry o wypłatach asymetrycznych. W tych pierwszych relacje między poszczególnymi wypłatami są takie same dla obu graczy, natomiast w tych drugich są ustalane osobno dla każdego z uczestników gry. W analizach wykorzystano gry o schematach interakcji typu: chicken i polowanie na jelenia. Modele gier przyjęły postać strategiczną. Wypłaty graczy odzwierciedlono graficznie (w formie wieloboków) na układach współrzędnych. Przeprowadzone analizy ukazują niewątpliwe zalety stosowania modeli teoriogrowych w badaniach politologicznych. Po pierwsze, modele teoriogrowe redukują analizowane zjawiska do niezbędnego minimum, pozwalając tym samym skoncentrować się badaczom na kluczowych aspektach zjawisk. Po drugie, język matematyki, którym posługuje się teoria gier, odznacza się niezwykłą precyzją oraz intersubiektywną komunikowalnością. Po trzecie wreszcie, stosowanie narzędzi teorii gier nie wymaga od badaczy znajomości rozbudowanego i skomplikowanego aparatu matematycznego.

On dynamic network security: A random decentering algorithm on graphs
Authors: Trobajo M.T. , Cifuentes-Rodríguez J. , Carriegos M.V.
Published: June 2018

Random Decentering Algorithm (RDA) on a undirected unweighted graph is defined and tested over several concrete scale-free networks. RDA introduces ancillary nodes to the given network following basic principles of minimal cost, density preservation, centrality reduction and randomness. First simulations over scale-free networks show that RDA gives a significant decreasing of both betweenness centrality and closeness centrality and hence topological protection of network is improved. On the other hand, the procedure is performed without significant change of the density of connections of the given network. Thus ancillae are not distinguible from real nodes (in a straightforward way) and hence network is obfuscated to potential adversaries by our manipulation.
Giving for Girls: Reconsidering Colonial Civilizing Missions in the Dutch East Indies through Charitable Girls’ Education
Authors: Kamphuis Kirsten
Published: June 2018

This article compares two Protestant schools for elite indigenous girls in the Dutch East Indies. While both schools were financially supported by the colonial government, they emerged from Christian organizations and were partly dependent on voluntary gifts from the Netherlands and the colony. The article proposes to look at such philanthropic initiatives as integral parts of a larger colonial civilizing mission which was not limited to the colonial state. On the contrary, discourses about the implementation of “civilized” gender roles within indigenous families through girls’ education first emerged among philanthropists, and eventually influenced state-driven educational policies for girls. It is argued that philanthropical initiatives for girls’ education such as the two schools presented here are best understood as attempts to gain control over, and ultimately reform, the domestic lives of the indigenous population in the Dutch East Indies

J Strength Cond Res 34(11): 3190–3198, 2020—The second lactate threshold (LT2) has previously been associated with endurance performance; however, comparisons between sexes are lacking regarding its efficacy. The aim of this study was to compare LT2 between men and women, specifically regarding its (a) relationship with endurance performance and (b) capacity to establish training and competition intensities. Competitive male (mean ± SD: age, 27.7 ± 4.7 years; V̇o
2max, 59.7 ± 5.2 ml·kg·min−1; n = 10) and female (mean ± SD: age, 27.3 ± 6.2 years; V̇o
2max, 54.5 ± 5.3 ml·kg−1·min−1; n = 12) cyclists and triathletes completed an incremental cycle trial to volitional fatigue (for determination of V̇o
2max and LT2 via the modified D-max method), a constant load (±5%) exercise trial of 30 minutes at LT2 power output, and a 40-km cycle time trial. The LT2 significantly correlated with 40-km cycling performance in both men (r = −0.69 to −0.77; p < 0.01–0.05) and women (r = −0.63 to −0.75; p < 0.01–0.05). All men sustained LT2 power output for 30 minutes, compared with 82% of women. Despite LT2 reflecting a similar heart rate, V̇o
2, and [La−] to those elicited during a 40-km time trial in both men and women, power output at LT2 was 6% higher (p < 0.05) than mean time trial power output in women, with no significant difference in men. Based on these findings, sex-specific recommendations have been suggested in regard to the use of LT2 for establishing performance potential, prescribing endurance training intensities and setting 40-km performance intensity.

Ihsan, M, Yeo, V, Tan, F, Joseph, R, Lee, M, and Aziz, AR. Running demands and activity profile of the new four-quarter match format in men's field hockey. J Strength Cond Res 35(2): 512–518, 2021—This study determined the running demands of men's field hockey with regards to the revised four-quarter match format. Twenty-eight male field hockey players were equipped with global positioning system units while competing in 14 competitive international games over a 1-year period. All matches allowed for unlimited substitutions, and consisted of four 15-minute quarters (i.e., Q1—Q4). A progressive decline in total distance (TD) was observed in Q2 (2,072 ± 141 m) to Q4 (2,055 ± 212 m) compared with Q1 (2,171 ± 195 m, p < 0.05). However, the decline in TD was due to decreases in low-intensity activity (<15 km·h−1, p < 0.05), as high-intensity running (HIR; >15 km·h−1) distances were similar throughout Q1—Q4 (p = 0.263). Positional data demonstrated a similar profile, where significant decreases in TD, but not in HIR, was observed across all playing positions at some point over the 4 quarters (p < 0.05). DEF accumulated the lowest amount of TD (7,631 ± 753 m), HIR (2,257 ± 498 m), and high-intensity decelerations (60 ± 9, >−2m·s−2) compared with MID and FWD (p < 0.05). By contrast, FWD performed the highest amount of HIR (3,090 ± 565 m) and high-intensity accelerations (110 ± 9, >2 m·s−2) compared with MID and DEF (p < 0.05). In conclusion, our results showed that although there was a progressive decline in TD over the 4 quarters of match play, high-intensity running performance (i.e., HIR and high-intensity acceleration) was maintained throughout the match regardless of playing position.
Les Grecs en Adriatique
Authors: Castiglioni Maria Paola
Published: June 2018

Située au carrefour entre les péninsules balkanique et italienne et reliant les espaces méditerranéens aux régions de l’Europe centrale et septentrionale, la mer Adriatique a connu une importante fréquentation grecque à partir au moins du IXe s. av. J.-C. Attirés par les opportunités commerciales auxquelles les littoraux de cette mer permettaient d’avoir accès, les Grecs ne s’y sont cependant qu’exceptionnellement installés de façon permanente dans le cadre de l’apoikía. À travers une présentation synthétique, cette contribution vise à mettre en évidence comment la « mobilité » grecque dans cette mer s’est insérée dans des contextes historiques plus vastes et complexes (la « tyrannie » de Périandre, les projets hégémoniques de Denys de Syracuse) et à souligner l’impact des implantations coloniales ou emporiques grecques sur les populations locales.

Phoenicians in the Mediterranean: diversified forms of contact
Authors: Nicolau Kormikiari Maria Cristina
Published: June 2018

In this article we approach the most recent developments on the research regarding the Phoenicians, a people who inhabited the coastal plains of eastern Mediterranean. We also approach the developments regarding their territorial expansion, especially towards the very opposite region in relation to their homeland: the western shores of the Mediterranean. We also discuss the pertinence of the use of such concepts as pre-colonization and colonization and present the position of some archaeologists drawn out of the Post-Colonial Theories.
Urbanismo regular, ocupação das terras e relações interétnicas na Magna Grécia
Authors: Pollini Airton
Published: June 2018

O Sul da Itália é provavelmente a região mais bem conhecida do Mundo Grego Antigo. Algumas fontes escritas, mas principalmente os estudos arqueológicos realizados desde um longo tempo permitiram o desenvolvimento de pesquisas em vários aspectos no cerne da temática da colonização grega. Este trabalho se concentra sobre três aspectos essenciais: a apropriação do espaço colonial, a interação com as populações indígenas e a urbanização das novas instalações.
The organization of the khora in southeastern Greek Sicily: Syracuse and its hinterland (733 -598 BC)
Authors: Florenzano Maria Beatriz Borba
Published: June 2018

Founded by Corinthians in Sicily in the 8th century, Syracuse soon became one of the biggest and more powerful poleis of the Greek world. During the first century of life in Sicily, the Syracusans founded in the hinterland four other settlements: Heloros, Akrai, Kasmene and Kamarina. This article intends to demonstrate, through the description of material data, that: 1. These foundations were enabled thanks to negotiation with local people and that Syracusan expansion was not exclusively a military/violent one; 2. Through these foundations, Syracuse established boundaries for its initial territorial expansion; 3. The empty space between Syracuse and these boundaries were filled up by degrees and in different conditions; 4. That this movement made by Syracuse allows us to better understand an inherent characteristic of the Greek ‘way of being’, i.e., territorial control

Determinants of Cash Holdings in Developed and Developing Countries
Authors: Rafinda Ascariena
Published: June 2018

This paper aims to find out the determinants of amount of cash holdings in developed and developing countries. One of the reason is because majority of studies that exist only focus on developed countries such as US or UK. Therefore, it is important to study cash holdings in the context of developing countries as well. Samples are drawn from DataStream Database using a sample period between 2009-2014 by including recent output with firm selection criterion based on data availability of firms (Al-Najjar, 2013), whereas financial firms with SIC codes 6000-6799 were not included as well as utility firms with SIC codes 4000-4999, resulting in total sample of 5402 observations from 23 countries. EViews was employed for the regression analysis with amount of cash holdings as the dependent variable. The results show that most of the hypotheses are not confirmed because of insignificant results and/or unexpected signs of coefficients. As the research about cash holdings in developing countries is not extensive yet, it is possible that there are differences to be found between developed and developing countries.

Published: June 2018

This study aims to analyze the effects of market power and type of ownership on bank’s income diversification in Indonesia, Malaysia, the Philippines, Thailand, and China. Banks diversifies their source of income to stabilize profitability level. Bank’s market power is a critical factor which affect its income diversification efforts. This study uses Lerner Index as a proxy for banks’ market power. By using a sample of 80 banks in five countries from 2012 to 2016 and operating Fixed Effect Model and Generalized Least Square, the result shows that banks with greater market power earn more non-interest income, except in the Philippines. Also, government ownership is proven to heighten the relation between market power and income diversification, with consistent results shown in each subsamples. Foreign ownership also heighten the relation between market power and income diversification, except in Thailand.

The purpose of this study are to analyze the performance of Universitas Negeri Gorontalo (UNG) in the financial and academic aspects; to analyze the gaps in financial performance and academic performance; and to know the differences in financial performance and academic performance before and after transformation into a State Universities Public Service Agency (PTN BLU). The analysis method used are descriptive analysis, gap analysis by calculating the average expected service level, and average calculation for perceived service actual performance, and t-test. The result of the research shows that the implementation of governance especially in the case of service is increasing and efficient. Besides that, after the transformation into BLU,UNG shows various progress, especially the improvement of financial performance as measured from income level from Non-Tax Revenue (PNBP), and from Revenue Budget and State Expenditure (APBN), while the academic performance, measured from 12 indicators covering tri darma of higher education, has increased significantly compared to when UNG is still part of the Work Unit (SATKER). While the results of gap analysis show that the academic and financial performance perceived by lecturers and UNG employees is higher than the quality of expectedservice. The financial performance of UNG before and after BLU has significant differences, as well as the academic performance.
Barrier in Design Innovation of Fashion Business: Evidence from Indonesian Moslem Fashion SME
Authors: Sari Rora P. , Asad Nabila
Published: June 2018

This paper aims to explore barriers that prevent Moslem fashion industry to adopt and indulge more innovative apparel and accesories design. As Moslem fashion gains more popularity in Indonesia, Moslem fashion is now adapting a more modern and contemporary approach rather than using the traditional method in designing the apparel and accessories product lines for the customers. Nevertheless, Moslem fashion industry also faced barriers in pursuing and creating an innovative product design in order to gain the competitive advantage in the industry. There were 70 personal communications conducted from SME Moslem fashion key personnels across Indonesia. This research applied qualitative approach, mostly using semi-structured interview’s techniques in exploring the barriers of innovation from each SMEs. As the result, it was found that human resource barrier (lack of skills and shortage of skilled staffs), operational resource barrier (rare raw materials and difficculties to find a high-quality material), financial problem (high cost in innovation, lack of fund and poor financial management) and imitations from competitors were the most prominent factors that prevent Moslem fashion SME brands to create innovative apparel design and innovative fashion product lines.
