Once You Know, You Are Responsible: The Road from Scholar to Activist
Authors: Siplon Patricia D. 
Published: December 2013

Abstract
Conventional wisdom usually argues that academic research should be conducted with the highest level of objectivity possible. I seek to turn that argument on its head and suggest that taking sides, even pursuing activist tactics, in support of our subjects' goals may be not only desirable but also the most ethical option. Drawing on my own experiences with research and activism in HIV/AIDS, first in the United States and later in East Africa, I present the case for the mutually beneficial relationship between scholarship and activism.
Seeds ofWeigela(Caprifoliaceae) from the Early Miocene of Weichang, China and the biogeographical history of the genus

Published: December 2013

AbstractSeeds of the genusWeigela(Caprifoliaceae) are described from the Early Miocene Hannuoba Formation of Weichang County, Hebei Province, China. They are flat, elliptic, with translucent membranous wings on three sides. Comparison with extant and fossil species ofWeigelaindicates that these seeds are different which therefore were assigned to a new species,Weigela weichangensis. On the basis of the fossil record, the distribution ofWeigelathrough geologic ages is shown on a series of palaeogeographic maps of the Northern Hemisphere. The oldest fossils ofWeigelaare seeds from the Oligocene of West Siberia, Asia. The genus later expanded into East Asia and Europe as well as into Arctic/Subarctic areas of North America via the North Atlantic Land Bridge and/or Bering Land Bridge in the Miocene.Weigeladisappeared from Europe and North America probably during the Pleistocene glaciations, but survived in Asia until now.

Authors: May Lin Ting , Siew Ping Then , Saptoro Agus , Freddie Panau 
Published: December 2013

Abstract
Bioactive compound, namely piperine, was extracted from Sarawak black pepper using supercritical carbon dioxide extraction. Experiments were carried outin the range of 3,000–5,000 psi (20.7–34.4 MPa) pressures, 318–328 K temperatures, 0.4–1 mm mean particle sizes and5–10 ml/min carbon dioxide flow rates. Experimental data analysis shows that extraction yield ismainly influenced by pressure, particle size and coupled-interactions between these two variables. Extraction process was modeled accounting for intraparticle diffusion and external mass transfer. The kinetics parameters for the internal and external mass transfers were evaluated and estimated. Mass transfer correlation was also developed. From simulation results, good agreement between experimental and simulated data has been found.
Preparation of graphene and inclusion in composites with poly(styrene-b-butadiene-b-styrene)
Authors: Czajka Michael , Shanks Robert A. , Kong Ing 
Published: December 2013

AbstractThe aim of this work was to prepare and characterize nanocomposites containing graphene from intercalated graphite. The graphene was produced by rapid thermal expansion using expandable graphite oxide or obtained commercially. The polymer used was poly(styrene-b-butadiene-b-styrene) (SBS). The SBS was dissolved in p-xylene and the graphene was ultrasonically suspended in the xylene solution. The morphology, dynamic mechanical, electrical, and thermal properties of composites were characterized. Graphene at 1% (w/w) (hydrogen atmosphere) was found to increase the storage modulus (68%) and loss modulus (147%) of the glassy state of polybutadiene in SBS. The damping factor of SBS was enhanced by 74% corresponding to the polystyrene phase of SBS using Cheap Tubes graphene. The composites were insulators at 1% (w/w). The styrene groups in SBS strongly adsorb onto the graphenes, preventing a percolation network that would enhance electrical permittivity. Graphene enhanced physical crosslinks of the polystyrene phase to increase the modulus at low concentration. Graphene dispersion using ultrasonic shear depended on π-π interactions between the aromatic rings of the solvent, graphene, and polystyrene. This is a simple, fast, cheap, and scalable way of making high-quality graphene and a new way of graphene dispersal in polymers.
Wenn Mülleimer sprechen können. Eine sprach- undmedienwissenschaftliche Analyse derWerbekampagne der Stadtreinigung Hamburg
Authors: Eggs Frederike 
Published: December 2013

Abstract
This paper analyses the clean-up campaign organised by Hamburg’s citycleaning service, SRH. Starting in May 2005, the SRH changed the colourof the city’s litter bins from mousey grey to signal red; they also used thelitter bins to advertise their own services using a variety of speech bubbleswhich were not immediately comprehensible, such as for example “Ihr Müllsieht rot.” (“Your rubbish sees red.”) oder “Ich steh’ frei.” (“I am free.”)These speech bubbles can be referred to as cryptic (litter-bin) utterances.The aim of this paper is to analyse the embedding of these cryptic utterancesin a specific space which is characterised by the presence of the redlitter bin. The analysis is intended to show that the two co-present elementsthat are communicatively relevant in this setting – the red litter bin on theone hand and the adhesive label bearing the cryptic utterance on theother – form a single entity in terms of their spatial-visual arrangement,but not in terms of their semiosis. On the contrary, the cryptic nature ofthese utterances – their ‘wittiness’ – is based on their linguistic “doublemeaning” (Freud 1905), which it is up to the recipient to decipher.

Smetana's “Vyšehrad” and Mythologies of Czechness in Scholarship
Authors: Pierre Kelly St. 
Published: December 2013

Abstract
Scholars have long framed similarities between Bedřich Smetana's “Vyšehrad” (the first movement of Má vlast) and Zdeněk Fibich's symphonic poem Záboj, Slavoj, and Luděk as a threat to Smetana's originality. In his biography of the composer, for example, Brian Large moved to “exonerate” Smetana from charges of “plagiarism” by arguing that Smetana began “Vyšehrad” at least two years before Záboj's premiere in 1874; not six months later as Smetana's diary attests. Rather than regarding these works' similarities as a problem, this discussion embraces their close relationships as a starting point. Situating both symphonic poems and their reception within the discourses generated by a powerful organization called the “Umělecká beseda” (“Artistic Society,” or UB, in which both Smetana and Fibich participated) illuminates the larger intellectual and aesthetic space from which they emerged. Such a process of contextualization reveals how both composers' works constructed each other and uncovers Smetana not as a “lone genius”—a composer untainted by influence—but as a participant in a shared conversation. Ultimately, this examination opens up new understandings of Smetana and his “Vyšehrad” and invites scholars to reengage with the deliberate subjectivity of Czechness and historiography more broadly.
Vitamin B12 Supplementation in Treating Major Depressive Disorder: A Randomized Controlled Trial
Authors: Syed Ehsan Ullah , Wasay Mohammad , Awan Safia 
Published: December 2013

Background/Objective:
Recent literature has identified links between vitamin B12 deficiency and depression.We compared the clinical response of SSRI-monotherapy with that of B12-augmentation in a sample of depressed patients with low normal B12 levels who responded inadequately to the first trial with the SSRIs.

Methods:
Patients with depression and low normal B12 levels were randomized to a control arm (antidepressant only) or treatment arm (antidepressants and injectable vitamin B12 supplementation).

Results:
A total of 199 depressed patients were screened. Out of 73 patients with low normal B12 levels 34 (47%) were randomized to the treatment group while 39 (53%) were randomized to the control arm. At three months follow up 100% of the treatment group showed at least a 20% reduction in HAM-D score, while only 69% in the control arm showed at least a 20% reduction in HAM-D score (p<0.001). The findings remained significant after adjusting for baseline HAM-D score (p=0.001).

Conclusion:
Vitamin B12 supplementation with antidepressants significantly improved depressive symptoms in our cohort.
Discussing Variance Analysis with the Performance of a Basketball Team
Authors: Strawser William R. , Strawser Jeffrey W. 
Published: December 2013

ABSTRACT
While current cost and managerial accounting texts devote extensive coverage to comparisons of actual and expected costs, relatively scant attention is devoted to analyzing comparable differences in revenues. Methods commonly used to identify differences between actual and expected revenues include the calculation of variances such as the sales price (SPV), sales quantity (SQV), and the sales mix (SMV) variances. We decided to approach the discussion of these variances in an innovative setting by presenting the SQV and SMV in the context of analyzing the performance of a basketball team, providing a setting that is both appropriate and interesting for illustrating revenue variances. Also, there are trade-offs in the choice between two of these “revenue” sources, for example, should the shooter attempt a two- or a three-point shot? Other relevant questions propel the decomposition of the SQV into the market size (MSV) and market share (MShV) variances. Was the game an offensive showdown, tallying numerous shots, or a defensive lock-down with relatively few shots? How effective was the team in controlling the ball and scoring a dominant proportion of shots? Feedback from students indicates that this illustration provides an interesting and comprehensive discussion of revenue variances. Using this and similar settings, a better understanding of quantity and mix variances, and the impact of these variances on improving performance, may be obtained.
Evaluation of Symmetric Neutral-Atmosphere Mapping Functions Using Ray-Tracing Through Radiosonde Observations
Authors: Souri A.H. , Sharifi M.A. 
Published: December 2013

Abstract
The aim of this paper is to compare the validity of six recent symmetric mapping functions. The mapping function models the elevation angle dependence of the tropospheric delay. Niell Mapping Function (NMF), Vienna Mapping Function (VMF1), University of New Brunswick- VMF1 (UNB-VMF1) mapping functions, Global Mapping Function (GMF) and Global Pressure and Temperature (GPT2)/GMF are evaluated by using ray tracing through 25 radiosonde stations covering different climatic regions in one year. The ray-traced measurements are regarded as “ground truth”. The ray-tracing approach is performed for diverse elevation angle starting at 5° to 15°. The results for both hydrostatic and non-hydrostatic components of mapping functions support the efficiency of online-mapping functions. The latitudinal dependence of standard deviation for 5° is also demonstrated. Although all the tested mapping functions can provide satisfactory results when used for elevation angles above 15°, for high precision geodetic measurements, it is highly recommended that the online-mapping functions (UNBs and VMF1) be used.The results suggest that UNB models, like VMF have strengths and weaknesses and do not stand out as being consistently better or worse than the VMF1. The GPT2/GMF provided better accuracy than GMF and NMF. Since all of them do not require site specific data; therefore GPT2/GMF can be useful as regards its ease of use.
Monitoring of the Aquatic Environment of an Industrial Area with Multiple Sources of Pollution
Authors: Pietrucin Dorota 
Published: December 2013

Abstract
Chemical plants are important objects of hydrogeological research, due to their potentially large impact on the soil and water environment. The topic of this paper is one of the oldest chemical plants in northern Poland, owned by the ‘Zachem’ company and located in the city of Bydgoszcz. The plant is located on a 500 ha property. This area has isolated about a dozen landfills for different types of wastes. In order to make a proper estimation of the influence of a chemical plant on its environment we must first identify the geological and hydrogeological conditions, and also the character of its land-use. Field investigations must be preceded by in-depth historical studies of the plant’s development and the technologies used within, and an identification of historical and present contamination sources. The author describes the current condition of the plant’s groundwater monitoring and indicates the direction of modernization and further development. This paper presents the problems faced when designing a groundwater monitoring network for industrial areas.
EOQ Revisited with Sustainability Considerations
Authors: Arslan M. Can , Turkay Metin 
Published: December 2013

Abstract
The economic order quantity (EOQ) model is a pure economic model in classical inventory control theory. The model is designed to find the order quantity so as to minimize total cost under a deterministic setting. In this study, we revise the standard EOQ model to incorporate sustainability considerations that include environmental and social criteria in addition to the conventional economic considerations. We propose models for a number of different policies and analyze these revised models. Based on our analysis, we show how the triple bottom line considerations of sustainability be appended to traditional cost accounting in EOQ model. We also provide a number of useful insights for decision and policy making practices.
Primal–Dual Type Evolutionary Multiobjective Optimization
Authors: Kaliszewski Ignacy , Miroforidis Janusz 
Published: December 2013

Abstract
A new, primal-dual type approach for derivation of Pareto front approximations with evolutionary computations is proposed.
At present, evolutionary multiobjective optimization algorithms derive a discrete approximation of the Pareto front (the set of objective maps of efficient solutions) by selecting feasible solutions such that their objective maps are close to the Pareto front. As, except of test problems, Pareto fronts are not known, the accuracy of such approximations is known neither.
Here we propose to exploit also elements outside feasible sets with the aim to derive pairs of Pareto front approximations such that for each approximation pair the corresponding Pareto front lies, in a certain sense, in-between. Accuracies of Pareto front approximations by such pairs can be measured and controlled with respect to distance between such approximations.
A rudimentary algorithm to derive pairs of Pareto front approximations is presented and the viability of the idea is verified on a limited number of test problems.
Genetic Algorithm Modification for Production Scheduling
Authors: Brzęczek Tomasz , Nowak Dariusz 
Published: December 2013

Abstract
Scheduling of production soundly affects its capacity especially if system does complex production jobs. In the theoretical part of the article an overview of the scheduling methods proposed in the literature was presented. In this paper it was stated a variant of job shop problem, in which jobs can overlap in some machines and omit others. Authors designed and presented here genetic algorithm to optimize solution of such a problem. The algorithm finds jobs sequence priority and in accordance with it schedules operations and calculates their completion time. An adequate problem was met in an examined plant, where 20 production jobs consisted of 11 to 20 operations assigned to at most 15 machines. Such big parameter numbers are crucial for big formal models and their solution algorithms. The designed algorithm proved to deal with parameters scale, as it found the schedule with 23,8% shorter jobs completion time in comparison with FIFO heuristic, that has been used so far by the plant.

Abstract
A soil moisture content map is important for providing information about the distribution of moisture in a given area. Moisture content directly influences agricultural yield thus it is crucial to have accurate and reliable information about moisture distribution and content in the field. Since soil is a porous medium modified generalized Archie’s equation provides the basic formula to calculate moisture content data based on measured ECa. In this study we aimed to find a more accurate and cost effective method for measuring moisture content than manual field sampling. Locations of 25 sampling points were chosen from our research field as a reference. We assumed that soil moisture content could be calculated by measuring apparent electrical conductivity (ECa) using the Veris-3100 on-the-go soil mapping tool. Statistical analysis was carried out on the 10.791 ECa raw data in order to filter the outliers. The applied statistical method was ±1.5 interquartile (IRQ) distance approach. The visualization of soil moisture distribution within the experimental field was carried out by means of ArcGIS/ArcMAP using the inverse distance weighting interpolation method. In the investigated 25 sampling points, coefficient of determination between calculated volumetric moisture content data and measured ECa was R2 = 0.87. According to our results, volumetric moisture content can be mapped by applying ECa measurements in these particular soil types.
Towards a Participatory, Co-operative and Sustainable Information Society?
Authors: Verdegem Pieter , Fuchs Christian 
Published: December 2013

Abstract
Sweden - like the other Nordic countries - is recognized as a leading IT nation. For this reason it is important to evaluate the specificities of Swedish policy discourses on the information society. The development of the information society has been a key topic in policy debates since the mid-1990s. More recently, new concepts such as ‘sustainable’ or ‘green knowledge society’ have emerged. This puts forward new questions about which type of information society we aim to achieve.
The present article contributes to the theoretical foundations of information society policies by introducing the notion of a participatory, co-operative, and sustainable information society (PCSIS). We apply this notion to Swedish policymaking by investigating ICT policy discourses. We also make a comparison with the recently launched Digital Agenda, the grand vision of the European Commission regarding the future of the information society.
Our overall conclusion is that Swedish and European visions can be labeled as dualistic and reductionist approaches, respectively. This means that both approaches fail to come up with a more elaborated perspective on the information society that links the key aspects participation, co-operation and sustainability in a convincing way. A dialectical approach, i.e. an approach that considers sustainability in multidimensional and interdependent aspects, is currently lacking in both Swedish and European policymaking.
Ironic Crisis Communication?
Authors: Vigsø Orla 
Published: December 2013

Abstract
Humour and irony are normally not recommended within crisis communication. So when the main Swedish rail company SJ in January 2011 issued three short videos taking an ironical stance on the company and its damaged reputation, it attracted a great deal of attention. But the good will generated by this unexpected irony was apparently never fully understood by the management, and was thus lost or directly undermined by their subsequent communication.
This article addresses the specific case of SJ’s crisis communication in early 2011, with particular interest in the question of the use of humour and irony in a crisis situation.
Changes of Physically-Chemical Parameters of 'Nante' Carrot Hybrids During Storage in Traditional Conditions
Authors: Augšpole Ingrīda , Rakčejeva Tatjana , Grāmatiņa Ilze 
Published: December 2013

Abstract
The current research focuses on changes of physically-chemical parameters of 'Nante' carrot hybrids during storage in traditional conditions. Quality parameters during carrot storage for six months at temperature 8 ± 2 oC and relative air humidity 85 ± 1 % were evaluated using standard methods: soluble solids (digital refractometer), dietary fibre (AOAC 985.29), ascorbic acid (iodometric) and firmness (TA.XT.plus Texture Analyser). Before storage, hybrids 'Nante/Berlikum', 'Nante/Maestro' and 'Nante/Bolero' had higher soluble solid content: 1.6 times higher comparing with hybrid 'Nante/Forto' and 1.2 times higher compared with hybrid 'Nante/Champion'. These hybrids also had higher ascorbic acid content: 2.0 times higher than in 'Nante/Forto' and 'Nante/Champion'. Significant differences were not found in dietary fibre content and firmness of non-stored carrots. Substantial differences were observed in soluble solid content in the hybrid 'Nante/Berlikum' during six-month storage - the content decreased 2.0 times. However, nonsignificant decrease of soluble solids content decreases was found for the hybrid 'Nante/Forto'. Changes in hybrid firmness and dietary fibre amount were not significant during storage for four months. Ascorbic acid content of the carrot hybrids during storage decreased by 3.4 times.
