‘Doing what needs to be done’: Understandings of UK-based community music – reflections and implications
Authors: Rimmer Mark 
Published: June 2015

Abstract
This article discusses two key themes emerging from a recent research network funded by the Arts and Humanities Research Council (AHRC), the aim of which was to improve understanding of the historic, current, and potential roles that community music (CM) can play in promoting community engagement in the United Kingdom. The network’s activities consisted of a series of themed meetings held in 2013 and 2014, which brought together practitioners and managers as well as academics, researchers, funders and commissioners. The article is divided into two parts, each addressing issues that emerged with some prominence across the network’s deliberations. The first part considers the vexed question of contemporary understandings of CM and the ways in which it was figured by the stakeholders involved in the network. The second section addresses the status of CM’s current relationship to what are often described as its ‘radical’ roots. In presenting contemporary CM practice in the United Kingdom as a ‘chameleonic’ practice embodying what was figured as a ‘quiet radicalism’, the network delegates drew attention, however inadvertently, to a number of enduringly challenging issues facing CM.

Organochlorine contaminants (PCBs, DDTs, HCB & HBDE) in fish from the Lake Varna and Lake Beloslav, Bulgaria
Authors: Georgieva Stanislava , Stancheva Mona , Makedonski Lubomir 
Published: June 2015

Abstract
Concentrations of organochlorine compounds such as polychlorinated biphenyls (PCBs), DDT and its metabolites, hexachlorobenzene (HCB) and hexachlorobutadiene (HBDE) were determined in three fish species: goby (Neogobius melanostomus), golden grey mullet (Mugil auratus) and silverside (Atherina boyeri). Samples were collected from the Lake Varna and the Lake Beloslav in 2014. The edible fish tissues were analyzed in order to investigate the presence of pollutants in species from the lakes near Varna City, Bulgaria and compared the results to the levels in other aquatic ecosystems. The fifteen congeners of PCBs, HCB, HCBD, DDT and its two main metabolites DDE and DDD were determined by capillary gas chromatography system with mass spectrometry detection. The OCPs levels in the wild fish were found in the order DDTs > PCBs. The other contaminants HCB and HCBD were not detected or were below the analytical detection limit. Among the pesticides, essentially only the metabolites p, p’- DDE and p, p’- DDD were found.
The concentrations of DDTs were determined from 2.66 to 17.97 ng/g wet weight and PCBs concentrations were found from 0.43 to 8.05 ng/g ww (in goby and golden grey mullet, respectively). The sum of the six Indicator PCBs did not exceed the European maximum limit 75 ng/g wet weight. The concentrations of DDTs and PCBs were found lower compared to those in similar fish species from other aquatic ecosystems.

Abstract
Major part of healthy human diet consist of marine fish and seafood products. And it is not surprising that there are numerous studies based on metal accumulation in various fish species. Fish may also be used for heavy metal monitoring programs of marine environments due to their easy sampling, sample preparation and chemical analysis. Concentrations of lead, cadmium, nickel, copper, manganese, zinc, iron, chromium, total mercury and total arsenic were determined in edible part of two commercially valuable fish Greek aquaculture species European sea bass (Dicentrarchus labrax) and gilthead sea bream (Sparus aurata) purchased from Bulgarian market during 2011. The concentration of metals was measured by atomic absorption spectrophotometry (AAS). The concentration of the heavy metals in examined fish species ranged as follow: Pb 0.008 - 0.013; Cd 0.0017 - 0.022; Ni 0.007 - 0.012; Cu 0.054 - 0.115; Mn 0.043 - 0.09; Zn 0.14 - 0.15; Fe 0.17 - 0.19; Cr 0.05 - 0.07; Hg 0.11 - 0.13; As 1.6 - 1.8 mg kg-1 wet weight, respectively.
The concentration of the heavy metals obtained from this study is compared with the results of a Black Sea bluefish (Pomatomus saltatrix) caught during the same year. The concentration of metals was significantly affected by the sampling site and fish species. Difference in the heavy metal concentration between European sea bass, gilthead sea bream is observed for Cu, Mn, Zn and Fe. Although, the heavy metals in the edible parts of the investigated fish were in the permissible safety levels for human uses.

Published: June 2015

AbstractAnimal studies have shown a neuroprotective effect of human serum albumin (sAlb) in ischemic stroke (IS). Previous studies have shown an association of high sAlb with better outcome. Our aim is to investigate the kinetics of sAlb in acute IS and its possible correlation with outcome taking into account the analytical and biological variation of sAlb measurement.In a prospective observational study, we enrolled 105 patients with acute IS. sAlb was measured upon admission, at 24 h, 48 h, 72 h and Day 7 thereafter. Stroke severity was assessed upon admission and at 72 h, and functional outcome on Day 7. Patients were divided into two groups according to functional outcome on discharge. Calculation of reference change value was used to assess the clinical significance of sAlb changes and multiple logistic regression to assess the independent association between variables and outcome.Fifty-one patients (48.6%) had poor outcome. Their sAlb levels exhibit a significant daily decrease until 72 h (35.9 g/L) compared to baseline (41.1 g/L) and remained low until Day 7 (36.0 g/L). These changes were clinically significant only from 72 h on. Among non-poor outcome patients a significant daily decrease until 72 h (40.9 g/L) was followed by recovery on Day 7 (41.2 g/L), but these changes were not clinically significant. sAlb was not independently associated with the functional outcome at any time-point.This study shows that sAlb levels might change during the first days after an acute IS, but these changes although statistically significant are not clinically significant if we take into account the analytical and biological variation of sAlb.
HsOrc4-dependent DNA remodeling of the ori-β DHFR replicator
Authors: Tomic Branko , Kusic-Tisma Jelena 
Published: June 2015

AbstractReplication of DNA in multicellular organisms initiates from origin of replication (ori) sequences, which significantly differ in length and complexity. One of the best characterized is hamster dihydrofolate reductase (DHFR), which contains the ori-β sequence with several functionally relevant domains, such as an AT-rich region, dinucleotide repeat element (DNR), sequence-induced bend DNA (BEND) and a RIP60 protein-binding site (RIP60). Prior to initiation, ori sequences are recognized by origin recognition complex (ORC), which is a hetero hexamer complex that serves as the landing pad for proteins of the pre-replication complex. The function of each ORC subunit is still unclear. In this study, we analyze the function of subunit 4 of the human ORC complex (HsOrc4) in interaction with a plasmid bearing the ori-β DHFR sequence. We show that the topologically closed DHFR ori-β replicator contains a bubble-like structure within its AT-rich region and that it is reversibly modified in the interaction with HsOrc4. The non-canonical structure of the AT-rich region in the topologically closed ori sequence is recognized and changed by HsOrc4 using the energy of supercoiled DNA. These findings could help to further elucidate DNA replication and its possible association with human genetic diseases.
Judgment evidence for statistical preemption: It is relatively better to vanish than to disappear a rabbit, but a lifeguard can equally well backstroke or swim children to shore
Authors: Robenalt Clarice , Goldberg Adele E. 
Published: June 2015

AbstractHow do speakers know when they can use language creatively and when they cannot? Prior research indicates that higher frequency verbs are more resistant to overgeneralization than lower frequency verbs with similar meaning and argument structure constraints. This result has been interpreted as evidence for conservatism via entrenchment, which proposes that people prefer to use verbs in ways they have heard before, with the strength of dispreference for novel uses increasing with overall verb frequency. This paper investigates whether verb frequency is actually always relevant in judging the acceptability of novel sentences or whether it only matters when there is a readily available alternative way to express the intended message with the chosen verb, as is predicted by statistical preemption. Two experiments are reported in which participants rated novel uses of high and low frequency verbs in argument structure constructions in which those verbs do not normally appear. Separate norming studies were used to divide the sentences into those with and without an agreed-upon preferred alternative phrasing which would compete with the novel use for acceptability. Experiment 2 controls for construction type: all target stimuli are instances of the caused-motion construction. In both experiments, we replicate the stronger dispreference for a novel use with a high frequency verb relative to its lower frequency counterpart, but only for those sentences for which there exists a competing alternative phrasing. When there is no consensus about a preferred way to phrase a sentence, verb frequency is not a predictive factor in sentences’ ratings. We interpret this to mean that while speakers prefer familiar formulations to novel ones, they are willing to extend verbs creatively if there is no readily available alternative way to express the intended meaning.

Wpływ właściwości fizykochemicznych stałych pozostałości z termicznego przekształcania osadów ściekowych na możliwość ich wykorzystania w ceramice czerwonej / The Influence of Incinerated Sewage Sludge Ashes Physical and Chemical Properties in Posibility of Usage in Red Ceramic
Authors: Stempkowska Agata , Kępys Waldemar , Pietrzyk Jacek 
Published: June 2015

Streszczenie
Przedmiotem niniejszej pracy jest przedstawienie właściwości fizykochemicznych stałych pozo- stałości z termicznego przekształcania komunalnych osadów ściekowych w aspekcie wykorzystania ich w produkcji ceramiki czerwonej. Wykorzystanie tego rodzaju odpadów jest sposobem na ich zagospodarowanie, a ponadto może wpłynąć na redukcję kosztów produkcji cegieł, przy zachowaniu założonych parametrów użytkowych oraz walorów estetycznych. Określono skład chemiczny i mine- ralny stałych pozostałości, zawartość naturalnych izotopów promieniotwórczych, skład granulo- metryczny oraz wymywalność soli rozpuszczalnych, mogących stanowić potencjalne zagrożenie oraz powodować wady materiałowe.
Kwarc stanowi główny składnik fazowy analizowanych materiałów, a jego zawartość dochodzi do 43% wag. Ilość ta z punktu widzenia właściwości ograniczających nadmierną plastyczność, powodującą odkształcenia materiału podczas procesu suszenia i wypalania, jest korzystna a popiół może być wykorzystany jako materiał schudzający, czyli substytut piasku.
Jedną z najczęstszych wad materiałowych ceramiki budowlanej jest powstawanie wykwitów solnych podczas kontaktuz wilgocią. Wykwity te spowodowane są obecnością w surowcach rozpusz- czalnych w wodzie jonów siarczanowych, które podczas użytkowania wyrobów migrują w porach i krystalizują na powierzchni w postaci białych osadów. Popioły KN1 i LN1 charakteryzują się bardzo wysoką zawartością tych jonów, wynikającą z procesu oczyszczania spalin (stosowanie wodoro- węglanu sodu), mogą być poważnym utrudnieniem w technologii produkcji cegieł, wręcz wyklu- czającym ich stosowanie w tym kierunku.
Popioły zawierają w swoim składzie metale, które potencjalnie mogą stanowić zagrożenie śro- dowiska, szczególnie wysoką koncentrację zaobserwowano w przypadku kationów miedzi i cynku. Badania wykazały, że tworzą one związki nierozpuszczalne, a ich wymywalność jest znacznie niższa niż wartości graniczne, a więc nic ma zagrożeń migracji szkodliwych kationów do gleby i wód gruntowych.

AbstractThe heating behavior and effect of experimental parameters like holding time, calcination temperature and microwave power on the weight loss of the mixed rare earth carbonate using microwave heating have been studied, also characterized by X-ray diffraction, thermogravimetry-differential scanning calorimetry, scanning electron microscopy (SEM), particle analysis and Fourier transform infrared (FT-IR). The results show the following: rare earth oxides are obtained at 850°C for holding 1 h; FT-IR analysis indicates that the vibration absorption peak of carbonate disappears after calcination using microwave, confirming the feasibility of microwave calcination for the rare earth carbonates; SEM shows that the rare earth oxides have the characteristics of better and finer particles, have better dispersion and have surface that is more loose and porous than that of products using conventional calcination; particle analysis indicates that average size (D

Published: June 2015

Abstract
Stilbenes are abundant in the heartwood of Scots pine (Pinus sylvestris L.) and are known to have strong antifungal efficiency. In this study, Scots pine sapwood blocks were impregnated with crude heartwood extract containing the stilbenes pinosylvin (PS) and the pinosylvin monomethyl ether (PSM). Impregnated blocks were submitted to brown-rot fungi, Coniophora puteana, Gloeophyllum trabeum, and Rhodonia (Poria) placenta, and fungal growth test and decay test were performed. Both tests showed that the impregnation with a high concentration of stilbenes (60 mg g-1 dry wood) significantly suppressed the growth of fungi and slowed down the decay process of wood blocks, especially in case of G. trabeum. However, chemical analysis showed that PS and PSM were degraded by all the three types of fungi, obviously via modification to resveratrol and methylresveratrol. Rhodonia placenta displayed the fastest rate of degradation. Thus, impregnation with biodegradable stilbenes could be a viable alternative for wood preservation only in service situations with low or transient risk of decay.

Abstract
To screen ionic liquid (IL) candidates for wood ionosolv pulping, swelling and viscoelastic studies on Norway spruce wood treated with ionic liquids have been conducted. In particular, the temperature dependency and kinetics of swelling in 1-butyl-3-methylimidazolium acesulfamate ([BMIM]Ace) and in 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc) were in focus. The kinetics of volumetric swelling in [BMIM]Ace yielded an E

a
of 54 kJ.mol-1 compared to 23 kJ.mol-1 in [EMIM]OAc. The viscoelastic behavior of IL-swollen wood was studied by dynamic mechanical analysis, and the lowest in situ glass transition temperature (T

g
) of lignin was ∼58°C and ∼65°C in [BMIM]Ace and in [EMIM]OAc, respectively. These T

g
values are lower than that found in water. Higher T

g
was calculated by the Gordon-Taylor equation, which means that swelling is not only due to the plasticizing effect of the ILs. SEM images showed that [EMIM]OAc has a stronger plasticizing effect than [BMIM]Ace. Overall, [EMIM]OAc is the most efficient agent for wood swelling, softening, and disintegration and, thus, it is the most promising candidate for ionosolv pulping.
On the Structure and Some Properties of LaCo Co-substituted NiZn Ferrites Prepared Using the Standard Ceramic Technique

Published: June 2015

AbstractZn0.5Ni0.5-xCoxFe2-yLayO4 ferrites (with x=0, 0.02 and y=0, 0.02) were prepared by an industrial method using the standard ceramic technique and sintered at 1,250°C in air. X-ray diffraction (XRD) was used to obtain the phase formation of the NiZn ferrites. The microstructure of ferrites was investigated by scanning electron microscopy (SEM). The XRD reveals that lattice parameter (a) is decreased and a secondary phase (LaFeO3) is formed in the La–Co co-substituted NiZn ferrite sample, meanwhile, the grain size (D) of this sample decreased obviously by observing SEM photographs. Vibrating sample magnetometry (VSM), B-H analyzer, impedance analyzer and electrometer were carried out in order to characterize some properties of the ferrites. This investigation indicates that, La–Co co-substituted NiZn ferrite sample has higher power loss (Pcv) than other samples at low frequency with an increase in coercive field (Hc) and magnetocrystalline anisotropy (K1), a decrease in initial permeability (μi) and saturation magnetization (Ms). However, at high frequency, the power loss of La–Co co-substituted sample is low, which is attributed to high resistivity (ρ), small grain size (D), less number of Fe2+ ions and low porosity (P).

Published: June 2015

Abstract
Iranian paddy (Fajr) is the most popular rice for export and consumption in Iran but it has poor milling yield. To solve this problem, parboiling has been used for improving its milling quality. In this study, the effect of various parboiling conditions (soaking at temperatures of 55–75°C and steaming times for 2–10 min) on some quality properties of Fajr paddy was investigated. After parboiling, the physical properties (degree of milling, head rice yield, lightness and color value) and mechanical properties (rupture force) of parboiled rice were measured. Head rice yield and mean value of rupture force increased significantly (p < 0.05) from 50.10% to 62.11–67.05% and from 108.6 to 128.93–227.30 N, respectively. Also, the color value of parboiled rice increased significantly (p < 0.05) by increasing the length of steaming time. The milling degree of unparboiled rice (17.03%) was significantly (p < 0.05) higher than that of the parboiled rice (15.1–16.9% range). Soaking at 65°C and 4 min steaming time gave the highest values of head rice yield, lightness and rupture force. So, this treatment was found to provide the most desirable quality of Fajr parboiled rice.
Exploring Links Between Dynamic Capabilities Perspective and Resource-Based View: A Literature Overview
Authors: Wójcik Piotr 
Published: June 2015

Abstract
The dynamic capabilities view posits that a firm’s success is largely driven by its ability to adapt to a changing environment to secure value creating potential and, thus achieve a competitive advantage. The dynamic capabilities perspective has attracted much scholarly attention in the last two decades, as reflected in the proliferation of conceptual and research articles in the strategic management literature. Knowledge about the relationship between dynamic capabilities and other theoretical concepts within the strategic management field remains limited. This paper therefore synthesizes the literature and uses it to develop a more clear relationship between notions of dynamic capabilities, resources, assets, competencies and static capabilities. Potential areas of future research are also outlined.
