Colloquium 1 The Place of Pleasure and Knowledge in the Fourfold Ontological Model of Plato’s Philebus
Authors: Ionescu Cristina
Published: May 2015

Plato’s Philebus develops an ontological model in four terms to account for “all the things that are now in the all” (23c4). The fourfold model consists of Limit, the Unlimited, the Mixture of these two, and the Cause of the mixture. Traditional interpretations place pleasure in the class of the Unlimited and knowledge either in that of Limit or, sometimes, in that of the Cause of mixtures. The aim of my paper is twofold: (a) it challenges the received interpretation and defends instead the view that pleasures, insofar as they are true, are placed in the class of Mixtures, while knowledge and its cognates are among Causes of mixtures, and (b) it explores some of the major implications of the right placement of pleasure and knowledge on the metaphysical map. In particular, I argue that Socrates’ identification of pleasure as a Mixture and of knowledge as Cause of mixtures accounts for the fact that we witness throughout the dialogue a gradual progression from the initial absolutely unbridgeable distance between pleasure and knowledge to an intimate collaboration between them. I suggest that this shift reflects a transition from the Phileban conception of pleasure as thoughtless thrill or sensation to the Platonic understanding of pleasure as cognitively structured experience that depends on our beliefs not only about factual situations, but also about the meaning and value of such situations for life generally.
Colloquium 3 Commentary on Giannopoulou
Authors: Partridge John
Published: May 2015

In these comments I express doubts about the success of one aspect of Giannopoulou’s intertextual reading of the Theaetetus and Alcibiades I. I argue that the role of interpersonal eros in prompting or bringing about self-knowledge in another is not adequately accounted for; it is not clear what an eros adds to the dialectic in the Alcibiades. If a robust role for eros as a vehicle of self-knowledge is sought, then the Phaedrus is the more illuminating dialogue because it shows how the lover and beloved are transformed by their eros. But comparisons to the Phaedrus would draw the Alcibiades away from the view of self-knowledge found in the Apology and in Giannopoulou’s interpretation of the Theaetetus.
Colloquium 4 Commentary on Hyland
Authors: Gordon Jill
Published: May 2015

In response to, but in keeping with, Hyland’s attention to specific dramatic features of Platonic dialogues, the commentary explores the issue of temporality in these dialogues and its role in their portrayal of the philosophical life. The explicit discussion and portrayal in these dialogues of diachronic time, in particular, reveals important aspects Socrates’ practice of philosophy.
God and Story in the Church and in Doctrine
Authors: Fiddes Paul S.
Published: May 2015

The paper aligns theological discussion about narrative theology with an empirical study of story-telling in a congregational setting, drawing conclusions about the ecclesial basis of method in doctrinal theology. It proposes to develop a narrative theology in a form that is inclusive of non-biblical narratives, drawing deductively upon story in Scripture and the past tradition of the church in constructing regulative doctrinal concepts for the community, while insisting that these must always be shaped inductively by the stories which people inhabit inside the church today, and outside the church in cultures which interpenetrate it. The paper offers a particular case-study of reflecting on stories from the Bible, church tradition and modern life among a group of young people of mainly West African heritage in the uk. From a ‘thick’ account of ‘everyday theology’ in the church, it offers suggestions for a reciprocal relation between deductive and inductive movements in making doctrine, taking as an example the doctrinal issue of ‘naming’.
Blueprint Ecclesiology and the Lived
Authors: Ward Pete
Published: May 2015

Normativity in Ecclesiology has tended to be based on a particular understanding of theology as blueprint. In the Ecclesiology and Ethnography Conversation there has been some dispute around how theological normativity should operate. This paper argues that theological knowledge arises from an ecclesial context of ‘abiding.’ This abiding is pneumatological in nature ‘like the wind’ and as such it is perilous. This point is argued with resort to a critical realist epistemology.
Practising Ecclesiology: From Product to Process
Authors: Watkins Clare
Published: May 2015

This paper positions theological action research methods of ecclesiology within current debates around ecclesiology and ethnography, and within theological reflections on postmodern culture. In relation to the first, it responds to Nicholas Healy’s proposal of ethnographic methods, and his more recent questionings of this approach, before, secondly, engaging with Lieven Boeve’s account of postmodern theology as a non-correlative attentiveness to dialogue and interruption. In each case the nature of the difficulties for practical ecclesiological approaches are rooted in the modern moves away from integrative, pre-modern approaches, towards more rationalised, systematised accounts of reality. Such modern accounts are seen as failing the incarnational theological instincts of Christian theology generally, and the concrete theological concerns of ecclesiology in particular. Theological Action Research offers a response to these contemporary challenges, envisioning ecclesiology as a discursive practice, which finds its identity in process and pedagogy, rather than in the construction of an ecclesiological ‘product,’ or model.

A new species of the stingless bee Trichotrigona (Hymenoptera: Apidae, Meliponini)
Authors: PEDRO SILVIA R. M. , CORDEIRO GUARACI DURAN
Published: May 2015

Trichotrigona camargoiana sp. nov. from Candeias do Jamari, Rondônia, Brazil is described and illustrated, along with nesting and behavior, as the second species of the rare and unusual genus Trichotrigona Camargo & Moure, 1983. The new species differs from T. extranea Camargo & Moure, 1983 by having plumose setae on the face and mesepisterna, wing setae predominantly yellow and black metatibia. The diagnosis for Trichotrigona is updated. As believed for T. extranea, T. camargoiana sp. nov. apparently does not store food and is a cleptobiotic social bee associated with Frieseomelitta.

A further note on the scientific name of Bullocks’ Oriole
Authors: CHESSER R. TERRY
Published: May 2015

Chesser (2013) intended to introduce a justified emendation to Icterus bullockii under Article 32.5.1 of the Code (ICZN 1999), because the name honors both William Bullock, Sr., and William Bullock, Jr. However, the correction bullockorum is "incorrect" and therefore is an unjustified emendation (Article 33.2.3). Under the assumption that the name Bullock was latinized (cf. Article 31.1.1) to Bullockius (bullocki– + the nominative case ending –us) and therefore that the name bullockii comprises the stem bullocki– + the genitive case ending –i, the justified correction bullockiorum is required.
Why Do Things Move People? The Jerusalem Temple as Emotional Repository
Authors: Barton Stephen C.
Published: May 2015

This article brings social-scientiﬁc method to bear on a biblical subject by asking the Durkheimian question, ‘Why do things move people?’, and asking it in relation to the Jerusalem temple. More speciﬁcally, drawing upon anthropological study of the emotions, an apparently neglected aspect of temple studies is opened up, namely, whether or not, and if so how, the power of the temple to ‘move’ people arose in part at least from its function as an emotional repository, the latter understood as consisting of material objects, persons, beliefs and practices that, in a highly concentrated way, constitute a ‘place’ where a people’s sense of identity, value and order are focused. At relevant points, implications for interpreting the affective aspect of New Testament ‘temple’ texts are offered.
The Trajectory of Emergence of Shared Group-Level Constructs
Authors: Allen Natalie J. , O’Neill Thomas A.
Published: May 2015

By examining 20 years of research conducted on groups (and teams), in field, academic, and laboratory settings, we used statistical aggregation indices to evaluate arguments that in newly formed groups, (a) evidence of the emergence of group-level shared constructs should be minimal and (b) evidence of the emergence of such constructs should increase over time/interaction. Puzzlingly, we found relatively little evidence supporting these arguments. Instead, emergence of group-level shared constructs seems evident very soon after group formation and, to the extent that this was possible to evaluate, emergence trajectories seemed to vary little across time. This pattern of findings is discussed with respect to both methodological and substantive issues, and we propose mechanisms that might explain what appears to be the surprisingly early emergence of group-level shared constructs.
Value Promise versus Value Delivery
Authors: Rao Ajit
Published: May 2015

This article is about the inevitability for organizations to move away from offering ‘commodity' customer service to an ‘on brand’ customer service. This article focuses on the need for organizations to align the promises that they are making while communicating the benefits of their brand with their current and potential customers, with the actual delivery of that promise. The benefits of such an alignment will result in stronger brand equity, greater customer centricity, increased levels of loyalty and concrete differentiation in the marketplace. The article begins with a review of the current situation of ‘on brand’ service gauging some of the reasons as to why delivery is not aligned with the promises made by the brand, and showcases some success stories. The article then discusses a tool that provides organizations with the ability to translate the brand promise into service delivery at every customer interaction resulting in authentic and memorable ‘moments-of-truth’ for the customer. This article is based on the author's experiences, observations, empirical evidence, and formal and informal discussions with his clients and non-clients.
What Value Does the Pharmaceutical Industry Bring to Health Care?
Authors: Laws David
Published: May 2015

It is very rare indeed for an industry to successfully push back against the tide and resist a changing business environment, and rarer still for it to continue to be profitable through those turbulent times. In many ways the pharmaceutical industry is unique. It has indeed managed to maintain, even grow its profitability during a period of unprecedented change and uncertainty.

The forces at play are significant and varied and apply across all of health care yet the notion of ‘value’ stands out as a key-driving concept.

Pharma has typically relied on ‘science’ and ‘product innovation around the pill' as the focus for the value they deliver but this is fast becoming not enough.With health care as a whole struggling to adapt to this new, changing environment how will big pharma respond.

Change does not come easily to this powerful behemoth and with so much money at risk the pharma industry will no doubt seek to focus on maintaining the status quo.
Crystal chemical formula for sartorite homologues

The members of the sartorite homologous series are complex sulfidesMe2+8N–16–2XMe3+16+XMe+XS8N+8whereMe2+is Pb andMe3+is As and Sb, whereasMe+is Ag and/or Tl. This paper presents calculation formulae for the homologue order N and for the separate substitution percentages for Tl + (As,Sb) ↔ 2Pb and Ag + (As,Sb) ↔ 2Pb substitutions. This enables one to evaluate the crystal chemistry and build a systematic classification of the sartorite homologues.
Causes of anomalous mineralogical diversity in the Periodic Table
Authors: Christy Andrew G.
Published: May 2015

When crustal abundance (A, measured in atomic parts per million) of a chemical element is plotted vs. number of mineral species in which that element is an essential constituent (S), a significantly positive correlation is obtained, but with considerable scatter. Repeated exclusion of outliers at the 90% confidence level and re-fitting leads, after the sixth iteration, to a steady state in which 40 of the 70 elements initially considered define a trend with logS= 1.828 + 0.255 log a (r= 0.96), significantly steeper than the original. Three other methods for reducing the effect of outliers independently reproduce this steeper trend. The 'diversity index'Dof an element is defined as the ratio of observed mineral species to those predicted from this trend.Dseparates elements into three groups. More than half of the elements (40 of 70) haveD= 0.5–2.0. Apart from these 'typical' elements, a group of 15 elements (Sc, Cr, Ga, Br, Rb, In, Cs, La, Nd, Sm, Gd, Yb, Hf, Re and Th) form few species of their own due to being dispersed as minor solid solution constituents, and a hitherto unrecognized group of 15 elements are essential components in unusually large numbers of minerals. The anomalously diverse group consists of H, S, Cu, As, Se, Pd, Ag, Sb, Te, Pt, Au, Hg, Pb, Bi and U, with Te and Bi by far the most mineralogically diverse elements (D= 22 and 19, respectively). Possible causes and inhibitors of diversity are discussed, with reference to atomic size, electronegativity and Pearson softness, and particularly outer electronic configurations that result in distinctive stereochemistry. The principal factors encouraging mineral diversity are: (1) Particular outer electronic configurations that lead to a preference for unique coordination geometries, enhancing an element's ability to form distinctive chemical compounds and decreasing its ability to participate in solid solutions. This is particularly noteworthy for elements possessing geometrically flexible 'lone-pair cations' with ans2outer electronic configuration. (2) Siderophilic or chalcophilic geochemical behaviour and intermediate electronegativity, allowing elements to form minerals that are not oxycompounds or halides. (3) Access to a wide range of oxidation states. The most diverse elements can occur as anions, native elements and in more than one cationic valence state.
Fluor-tsilaisite, NaMn3Al6(Si6O18)(BO3)3(OH)3F, a new tourmaline from San Piero in Campo (Elba, Italy) and new data on tsilaisitic tourmaline from the holotype specimen locality
Authors: Bosi Ferdinando , Andreozzi Giovanni B. , Agrosi Giovanna , Scandale Eugenio
Published: May 2015

Fluor-tsilaisite, NaMn3Al6(Si6O18)(BO3)3(OH)3F, is a new mineral of the tourmaline supergroup. It occurs in an aplitic dyke of a LCT-type pegmatite body from Grotta d'Oggi, San Piero in Campo, Elba Island, Italy, in association with quartz, K-feldspar, plagioclase, elbaite, schorl, fluor-elbaite and tsilaisite. Crystals are greenish yellow with a vitreous lustre, sub-conchoidal fracture and white streak. Fluor-tsilaisite has a Mohs hardness of ∼7 and a calculated density of 3.134 g/cm3. In plane-polarized light, fluor-tsilaisite is pleochroic (O = pale greenish yellow and E = very pale greenish yellow), uniaxial negative. Fluor-tsilaisite is rhombohedral, space group R3m, a = 15.9398(6), c = 7.1363(3) Å, V = 1570.25(11) Å3, Z = 3. The crystal structure of fluor-tsilaisite was refined to R1 = 3.36% using 3496 unique reflections collected with MoKα X-ray intensity data. Crystal-chemical analysis resulted in the empirical formula: X(Na0.69〈0.29Ca0.02)Σ1.00Y(Mn2+1.29Al1.21Li0.56Ti0.03)Σ6.00ZAl6T(Si5.98Al0.03)Σ6.00B2.92O27V(OH)3W[F0.39(OH)0.25O0.36]Σ1.00.

Comparisons were performed between fluor-tsilaisite and a tsilaisitic tourmaline from the same locality as the holotype specimen. This latter tourmaline sample was selected for this study due to its remarkable composition (MnO = 11.63 wt.%), the largest Mn content found in tourmaline so far.

Fluor-tsilaisite is related to tsilaisite through the substitution WF ↔ W(OH) and with fluor-elbaite through the substitution Y(Al + Li) ↔ 2YMn2+, and appears to be a stepwise intermediate during tourmaline evolution from tsilaisite to fluor-elbaite.
Temperature- and moisture-dependent powder X-ray diffraction studies of kanemite (NaSi2O4(OH)·3H2O)

Published: May 2015

The high-temperature- and moisture-dependent behaviour of synthetic kanemite (NaSi2O4(OH)·3H2O orSKS-10) has been studied byin situpowder X-ray diffraction. Heating experiments in the range between ambient temperatures and 250°C confirm earlier investigations that the dehydration of kanemite occurs in two steps. According to our results the two different reactions start at ∼30 and 75°C. The dehydration products have the following compositions: NaSi2O4(OH)·H2O (monohydrate) and NaSi2O4(OH), respectively. The crystal structures of both phases have been solved at ambient conditionsab initiofrom laboratory powder diffraction data using samples that have been carefully dehydrated at 60 and 150°C, respectively, and refined subsequently by the Rietveld method. Basic crystallographic data are as follows: NaSi2O4(OH)·H2O: orthorhombic, space groupPna21,a= 7.2019(1),b= 15.3252(2),c= 4.8869(1) Å,V= 539.37(1) Å3,Z= 4; NaSi2O4(OH): monoclinic, space groupP21,a= 6.3873(1),b= 4.8876(1),c= 7.1936(1) Å, β = 93.36(1)°,V= 224.19(1) Å3,Z= 2. Both compounds belong to the group of single-layer silicates based on Si2O4(OH) sheets. The sodium cations are located between the tetrahedral sheets and are surrounded by oxygen atoms from silicate anions and/or water molecules. Depending on the dehydration step the coordination numbers of the alkali ions vary between six (kanemite) and five (NaSi2O4(OH)). Kanemite and its two dehydration products show structural similarities which are discussed in detail. Moisture-dependent diffraction studies at ambient temperatures indicate that kanemite is stable between 10% and at least 90% relative humidity. Below the lower threshold a transformation to the monohydrate phase was observed. Dehydration and rehydration as a function of humidity is reversible. However, this process is combined with a significant loss of crystallinity of the samples.
As-bearing new mineral species from Valletta mine, Maira Valley, Piedmont, Italy: II. Braccoite, NaMn2+5 [Si5AsO17(OH)](OH), description and crystal structure

Published: May 2015

The new mineral species braccoite, ideally NaMn2+5[Si5AsO17(OH)](OH), has been discovered in the Valletta mine dumps, in Maira Valley, Cuneo province, Piedmont, Italy. Its origin is probably related to the reaction between ore minerals and hydrothermal fluids. It occurs as subhedral crystals in brown-red coloured thin masses, with a pale-yellow streak and vitreous to resinous lustre. Braccoite is associated with tiragalloite, for which new data are provided, as well as gamagarite, hematite, manganberzeliite, palenzonaite, quartz, saneroite, tokyoite, unidentified Mn oxides, organic compounds, and Mn arsenates and silicates under study.

Braccoite is biaxial positive with refractive indices α = 1.749(1), β = 1.750(1), γ = 1.760(1). It is triclinic, space group P1̄, with a = 9.7354(4), b = 9.9572(3), c = 9.0657(3) Å, α = 92.691(2), β = 117.057(4), γ = 105.323(3)°, V = 740.37(4) Å3 and Z = 2. Its calculated density is 3.56 g/cm3. The ten strongest diffraction lines of the observed powder X-ray diffraction (XRD) pattern are [d in Å, (I), (hkl)]: 3.055 (69)(22̄1), 3.042 (43)(102), 3.012 (65)(32̄1̄), 2.985 (55)(23̄1̄), 2.825 (100)(213̄), 2.708 (92)(220), 2.627 (43)(23̄2̄), 2.381 (58)(41̄1̄), 2.226 (25)(214̄) and 1.680 (433̄)(36). Chemical analyses by wavelength-dispersive spectroscopy electron microprobe gave (wt.%): Na2O 4.06, CaO 0.05, MnO 41.76, MgO 0.96, Al2O3 0.04, CuO 0.02, SiO239.73, As2O5 6.87, V2O5 1.43, SO3 0.01 and F 0.04. H2O 2.20 was calculated on the basis of 2OH groups p.f.u. Raman spectroscopy confirmed the presence of (SiO4)4–, (AsO4)3– and OH groups. The empirical formula, calculated on the basis of Σ cations-(Na,K) = 11 p.f.u., in agreement with the results of the crystal structure, is Na1.06(Mn2+4.46Mn3+0.32Mg0.19V3+0.01Al0.01Ca0.01)[Si5(As0.48Si0.37V5+0.15)O17(OH)](OH0.98F0.02); the simplified formula is Na(Mn,Mg,Al,Ca)5[Si5(As,V,Si)O17(OH)](OH,F).

Single-crystal XRD allowed the structure to be solved by direct methods and revealed that braccoite is the As-dominant analogue of saneroite. The structure model was refined on the basis of 4389 observed reflections to R1 = 3.47%. Braccoite is named in honour of Dr Roberto Bracco (b. 1959), a systematic minerals collector with a special interest in manganese minerals. The new mineral was approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification (IMA 2013-093).

Background

Next-generation sequencing technologies provide new opportunities to identify the genetic components responsible for trait variation. However, in species with large polyploid genomes, such as bread wheat, the ability to rapidly identify genes underlying quantitative trait loci (QTL) remains non-trivial. To overcome this, we introduce a novel pipeline that analyses, by RNA-sequencing, multiple near-isogenic lines segregating for a targeted QTL.

Results

We use this approach to characterize a major and widely utilized seed dormancy QTL located on chromosome 4AL. It exploits the power and mapping resolution afforded by large multi-parent mapping populations, whilst reducing complexity by using multi-allelic contrasts at the targeted QTL region. Our approach identifies two adjacent candidate genes within the QTL region belonging to the ABA-induced Wheat Plasma Membrane 19 family. One of them, PM19-A1, is highly expressed during grain maturation in dormant genotypes. The second, PM19-A2, shows changes in sequence causing several amino acid alterations between dormant and non-dormant genotypes. We confirm that PM19 genes are positive regulators of seed dormancy.

Conclusions

The efficient identification of these strong candidates demonstrates the utility of our transcriptomic pipeline for rapid QTL to gene mapping. By using this approach we are able to provide a comprehensive genetic analysis of the major source of grain dormancy in wheat. Further analysis across a diverse panel of bread and durum wheats indicates that this important dormancy QTL predates hexaploid wheat. The use of these genes by wheat breeders could assist in the elimination of pre-harvest sprouting in wheat.
Biomonitoring of metal contamination in estuarine ecosystem using seagrass
Authors: Ahmad Faridahanim , Azman Shamila , Said Mohd Ismid Mohd , Baloo Lavania
Published: May 2015

Metals concentrations (As, Cd, Cu, Hg and Pb) in seawater, sediment and the seagrass (Enhalus acoroides) were analysed at Pulai River estuary, Johor Straits, Malaysia. In this research, Enhalus acoroides was used in order to find it’s efficiency in up taking metals with a role in phytoremediation. Seawater, sediment and Enhalus acoroides samples were collected, and data of Pearson’s correlation coefficients were analysed using SPSS 16 software. Results show that lead levels were the highest metal content in Enhalus acoroides (202 ± 102 μg/gDW), seawater (268 ± 190 μg/L) and sediment (248 ± 218 μg/gDW), compared to other metals. There was a positive correlation for metal concentrations between Enhalus acoroides and sediment, but no correlation was found between Enhalus acoroides with seawater at estuarine area may be caused by inconsistent metal concentrations in seawater due to the influences of tidal changes and stormy waves. This indicates that Enhalus acoroides is a species possessing the capabilities to uptake metals from sediment, and suitable to act as both a phytoremediator and biomonitor in estuarine ecosystems due to sharp sensitivity to variation in the environment.
Pressure Overload-Induced Cardiac Dysfunction in Aged Male Adiponectin Knockout Mice Is Associated With Autophagy Deficiency
Authors: Jahng James Won Suk , Turdi Subat , Kovacevic Vera , Dadson Keith , Li Ren-Ke , Sweeney Gary
Published: May 2015

Heart failure is a leading cause of death, especially in the elderly or obese and diabetic populations. Various remodeling events have been characterized, which collectively contribute to the progression of heart failure. Of particular interest, autophagy has recently emerged as an important determinant of cardiac remodeling and function. Here, we used aged, 13-month-old, male adiponectin knockout (Ad-KO) or wild-type (wt) mice subjected to aortic banding to induce pressure overload (PO). Cardiac strain analysis using speckle tracking echocardiography indicated significant dysfunction at an earlier stage in Ad-KO than wt. Analysis of autophagy by Western blotting for Light Chain 3 or microtubule-associated proteins 1B and Sequestosome 1 together with transmission electron microscopy of left ventricular tissue indicated a lack of PO-induced cardiac autophagy in Ad-KO compared with wt mice. Associated with this was mitochondrial degeneration and evidence of enhanced endoplasmic reticulum stress. Western blotting for Light Chain 3 or microtubule-associated proteins 1B, examination of flux using tandem fluoresent tagged-Light Chain 3, and analysis of lysosomal activity in H9c2 cardiac myoblasts treated with adiponectin indicated that adiponectin enhanced autophagy flux. In conclusion, adiponectin directly stimulates autophagic flux and the lack of autophagy in response to PO in aged mice lacking adiponectin may contribute to cellular events which exacerbate the development of cardiac dysfunction.

Generalized friezes and a modified Caldero–Chapoton map depending on a rigid object
Authors: Holm Thorsten , Jørgensen Peter
Published: May 2015

The (usual) Caldero–Chapoton map is a map from the set of objects of a category to a Laurent polynomial ring over the integers. In the case of a cluster category, it maps reachable indecomposable objects to the corresponding cluster variables in a cluster algebra. This formalizes the idea that the cluster category is a categorification of the cluster algebra. The definition of the Caldero–Chapoton map requires the category to be 2-Calabi-Yau, and the map depends on a cluster-tilting object in the category. We study a modified version of the Caldero–Chapoton map which requires only that the category have a Serre functor and depends only on a rigid object in the category. It is well known that the usual Caldero–Chapoton map gives rise to so-called friezes, for instance, Conway–Coxeter friezes. We show that the modified Caldero–Chapoton map gives rise to what we call generalized friezes and that, for cluster categories of Dynkin type A, it recovers the generalized friezes introduced by combinatorial means in recent work by the authors and Bessenrodt.
Ti-Ni-O Reactive Nanocomposite Electrodeposition Using Ti Nanoparticles and Annealing
Authors: Arakawa Tomiyuki , Watanabe Nobuaki , Haijima Yuki , Matsumura Ayaka , Koiwa Ichiro
Published: May 2015

Ti-Ni-O nanocomposites were prepared by electrodeposition using Ti nanoparticles of 100 nm in diameter, and subsequent annealing at 600 °C in a vacuum of 1 × 10−4 Pa for one hour. Scanning electron microscopy revealed that clusters of 2 to 15 µm were observed on the surface of Ti-Ni-O nanocomposites. The number of clusters increased with increasing the concentration of Ti nanoparticles in electrodeposition baths. Glow discharge-optical emission spectroscopy showed that Ti concentration in Ti-Ni-O nanocomposites increased with increasing Ti nanoparticles in baths, and the Ti concentration was saturated for Ti nanoparticles of more than 20 g dm−3. Ti atoms of approximately 18 wt % were distributed in Ti-Ni-O nanocomposites. Furthermore, although a Ni(200) peak from Ni electrodeposits was increased by annealing, the increase in Ni(200) peak from Ti-Ni-O nanocomposites was suppressed. X-ray photoelectron spectroscopy analysis indicated that the dominant structure was changed from Ni oxides, Ni(OH)2 and Ni to TiO2 on the surface of Ti-Ni-O nanocomposites by annealing. In fact, Ti-Ni-O nanocomposites in methylene blue reduced the absorbance with wavelength of 664 nm after UV irradiation with the wavelength of 350 nm. It is possible that proposed reactive nanocomposites formation offers a novel TiO2 coated Ti-Ni-O system.
The five deadly sins of science publishing
Authors: Tracz Vitek
Published: May 2015

Science cannot progress without scientists reporting their findings. And yet researchers have given control of this central pillar of the scientific process to science publishers, who are in the business of serving the interests of their journals; these are not always the same as the interests of science. This editorial describes the problems with the process of preparing and publishing research findings, and with judging their veracity and significance, and then explains how we at Faculty of 1000 are starting to tackle the ‘deadly sins’ of science publishing.
The impact of minor injury unit closures on travel time and attendances
Authors: Chalk Daniel , Pltt Martin
Published: May 2015

Geographic modelling techniques provide a means of optimising the location of services, or understanding the potential impact of geographic service reconfigurations. In response to commissioner queries, we assessed the potential impact on patient travel time and attendances of the closure of four minor injury units (MIUs) in a locality of South West England. We used the MPMileCharter add-in for Microsoft MapPoint and the attendance records of 90 252 minor injury unit patients to calculate car travel time data to the units in the locality. We then built a geographic model of the existing configuration of MIUs in Microsoft Excel, and used ‘what if’ analysis to determine the potential impact of the proposed closures. The model predicted that if the four MIUs were closed, there would be only a trivial increase in average travel time across all patients, but a significant increase of around 20 minutes per patient for those whose nearest unit was closed. The model also predicted that the closure of one of the MIUs could lead to significant increased demand at the walk-in centre located at the acute hospital. Using these results, the local commissioners decided to close only three of the four units.

Published: May 2015

O estudo objetiva identificar a área de abrangência da contabilidade gerencial na visão dos docentes que atuam nos cursos de ciências contábeis das Instituições de Ensino Superior (IES) do sistema ACAFE (Associação Catarinense das Fundações Educacionais) de Santa Catarina - Brasil. Pesquisa descritiva quantitativa foi realizada por meio de uma survey, com aplicação de um questionário de perguntas fechadas. A população compreende os docentes dos cursos de ciências contábeis das 15 IES ligadas ao sistema ACAFE e a amostra dos 40 docentes de nove universidades que responderam ao questionário. Os resultados mostram que na visão dos docentes pesquisados, as principais temáticas de abrangência da contabilidade gerencial são: informações contábeis para tomada de decisão; custos para avaliação, controle e tomada de decisão; controle gerencial por áreas de responsabilidade; avaliação de desempenho e lucro empresarial. Comparando-se os resultados com pesquisa idêntica realizada no estado do Paraná, constatou-se que as informações contábeis para tomada de decisão e custos para avaliação, controle e tomada de decisão foram itens convergentes, considerados muito importantes.
ESTRATÉGIAS COMPETITIVAS E POTENCIAL DE BARREIRAS DE ENTRADA EM SERVIÇOS: UMA PROPOSTA DE ABORDAGEM TEÓRICA
Authors: Meirelles Dimária Silva e
Published: May 2015

O objetivo deste artigo é apresentar uma proposta de abordagem teórica para estratégias competitivas e barreiras de entrada em serviços. Utiliza-se uma definição de serviços baseada no pressuposto de que o processo de trabalho pode ser humano ou mecânico, com a utilização tanto de recursos humanos quanto máquinas e equipamentos. Dessa perspectiva propõe-se uma matriz de classificação das estratégias competitivas em serviços baseada em duas variáveis: grau de intensidade de capital e escala de operação. Quatro possibilidades de prestação do serviço e as respectivas estratégias competitivas são identificadas: i) baixa intensidade de capital e pequena escala de operação – estratégias voltadas para a reputação e fidelização de clientes; ii) baixa intensidade de capital e larga escala de operação – estratégias baseadas no controle e padronização de procedimentos; iii) alta intensidade de capital e pequena escala de operação – estratégias de inovação e aumento do conteúdo tecnológico; e iv) alta intensidade de capital e larga escala de operação – estratégias de exploração de economias de escala. Em seguida, propõe-se uma matriz que conecta essas estratégias com barreiras de entrada, as quais podem ser relacionais, de custo, tecnológicas e de escala.

Published: May 2015

Este artigo aborda a relevância da questão ambiental no processo de tomada de decisão de compras organizacionais no setor de papel e celulose. Discute-se a relação entre questão ambiental e decisão de compra. Após a apresentação e discussão do conceito de tomada de decisão, discute-se o Marketing Verde como estratégia organizacional para informar o mercado sobre as iniciativas ambientais da organização. Esse conceito tem sido abordado como parte dos esforços para compreender o lugar da variável ambiental nas dinâmicas organizacionais e sociais. Com base na relação de empresas disponibilizadas pela Federação das Indústrias dos Estados, foram coletados dados de 36 empresas compradoras do setor de papel e celulose. Os dados coletados e sua posterior análise mostraram fortes evidências de que a questão ambiental parece não afetar as preferências dos compradores institucionais do setor no momento da decisão de compra. Na mesma linha, conclui-se que não há conhecimento satisfatório das práticas ambientais reais das empresas por parte dos compradores.

O recrudescimento da competição e o crescimento de vagas não ocupadas caracterizam a situação de algumas instituições que oferecem o curso de Administração. Essa condição é agravada pela deficiência de dados sobre condicionantes para a escolha dessa carreira e de uma dada instituição de ensino. O presente trabalho, considerando esse cenário competitivo, se propôs desenvolver uma investigação dirigida ao mapeamento de aspectos associados à seleção de Administração como curso superior e à escolha da instituição de ensino superior como ofertante do serviço, focalizando a pesquisa na região do ABC Paulista. Numa primeira fase, de caráter exploratório, por meio de entrevistas com especialistas, levantaram-se motivos vinculados às escolhas. Seguiu-se uma investigação descritiva, com entrevistas a 1635 estudantes. Empregando-se instrumental multivariado, foram identificados cinco fatores para a opção pelo Curso de Administração: potencialidade, afinidade, continuidade, acessibilidade e familiaridade com a carreira. Para a escolha da instituição, quatro fatores foram levantados: infra-estrutura, imagem, indicação e acessibilidade, oferecendo-se dados efetivos para decisões de operação, de oferta de serviços e de comunicação junto às instituições.

Published: May 2015

Este trabalho, de caráter exploratório, tem como objetivo estudar o que é valor em serviços educacionais à distância na perspectiva do aluno. Visando conhecer o comportamento do aluno, foi utilizada como base a teoria de means-end, que representa hierarquicamente as conexões entre atributos (A), consequências (C) e valores (V), com o apoio da técnica laddering. A amostra configurou-se em 36 questionários aplicados a alunos de pós-graduação à distância do curso de Especialização em Administração Pública, oferecido pela Universidade Castelo Branco (UCB), em parceria com o Departamento de Ensino e Pesquisa do Centro de Estudos de Pessoal do Exército Brasileiro (DEP/CEP/EB). Os resultados incluem a construção de um mapa hierárquico de valor, no qual se identificam como elementos da cadeia dominante: Material Didático (como atributo), Aprendizagem (como consequência de uso) e Desenvolvimento Profissional e Desenvolvimento Pessoal (como valores).

Published: May 2015

Esta investigação desenvolve estudo exploratório descritivo sobre o ensino de administração em quatro universidades, duas brasileiras e duas estrangeiras. Caracteriza as atividades relacionadas à gestão acadêmica e organizacional do ensino nessas universidades. O procedimento metodológico de pesquisa fundamenta-se em abordagem interpretativa, envolvendo estudantes, professores e gestores universitários que conhecem ambas as realidades envolvidas na investigação e levando-se em conta apenas as informações da pesquisa consideradas como unânimes pelos participantes. Compreendeu-se, pelos indícios, que o ensino de administração nas duas universidades brasileiras é percebido por cometer falha significativa nos processos pesquisados, comprometendo, inclusive, o preparo na profissionalização dos alunos. Verifica-se, portanto, a necessidade de repensar a institucionalização e os diferentes papéis da gestão acadêmica, principalmente no que diz respeito não apenas ao conteúdo e aos processos de ensino, mas também à dinâmica da estrutura acadêmica e da avaliação
IMAGINAÇÃO ADMINISTRATIVA: A CIDADE COMO ESPAÇO E FONTE DA APRENDIZAGEM
Authors: Medeiros Cintia Rodrigues de Oliveira , Borges Jacquelaine Florindo
Published: May 2015

Em estudo clássico, em 1954, Mills (1975) chamou de imaginação sociológica uma qualidade de espírito imprescindível para que os indivíduos pudessem, a despeito da agitação de sua experiência diária, superar a falsa consciência de suas posições sociais. Nós nos inspiramos
no conceito de Mills, nos estudos da pedagogia crítica e nos Critical Management Studies para propor o conceito imaginação administrativa: uma habilidade requerida dos administradores que lhes permite conhecer, sentir, refletir, aprender e ter esperança sobre a sua condição histórica, sua posição social, suas perturbações pessoais e sua participação cidadã nas
questões públicas da estrutura social. Neste artigo, descrevem-se a utilização e os resultados de uma prática pedagógica sustentada nesse conceito. Para a condução dessa atividade pedagógica, os estudantes de uma turma do curso de graduação em Administração são estimulados e orientados a utilizar a arte fotográfica, a pesquisa de campo e o arcabouço
conceitual da área de formação para analisar situações reais da cidade em que vivem. Os resultados deste estudo mostram que essa atividade promoveu a imaginação administrativa dos estudantes ao estimular a reflexão sobre o compromisso do gestor com a sociedade e seu papel social.

O artigo discute os Mestrados Profissionais (MPs) tento como referência os Mestrados Acadêmicos (Mas). Entende-se que pesquisas desenvolvidas a respeito dos MPs podem contribuir para a compreensão e desenvolvimento desse tipo de curso. Para isso, verificou-se a necessidade de traçar algumas considerações e contraposições em relação às ideias
que perpassam as modalidades de MP e MA com o objetivo compreender suas convergências, divergências e desafios. O foco da análise foi direcionado aos cursos da área de Administração. Assim, com base na literatura disponível, na legislação, em dados obtidos por meio da internet
sobre os programas de mestrado em Administração no Brasil reconhecidos pela CAPES, e dados obtidos por contato eletrônico e telefônico, foi possível identificar as características, o histórico e a regulamentação de mestrado profissional e acadêmico no Brasil. Evidenciaram-se alguns pontos relevantes que caracterizam os cursos tais como o perfil discente e docente, o formato do trabalho de conclusão, o destino do egresso, o financiamento dos cursos e a forma de avaliação. A análise revelou o papel relevante do governo brasileiro na constituição e
consolidação dos MAs e MPs. 
ESTRATÉGIA: ACORDOS, DESACORDOS E REVISÕES SOBRE O TEMA
Authors: Meirelles Anthero de Moraes , Gonçalves Carlos Alberto
Published: May 2015

Amplamente utilizado nas teorias organizacionais e gerenciais contemporâneas, e no universo discursivo da consultoria empresarial, o termo estratégia se tornou alvo de atenção e de significados, definições e modelos diversos. Autores celebram esta diversidade, ou pelo menos a
consideram inevitável, em função da riqueza semântica do vocábulo e da natureza intrinsecamente complexa e mutável daquilo que se acostumou tratar como estratégia no contexto das organizações (MINTZBERG; LAMPEL; AHLSTRAND, 2000; SMIRCICH; STUBBART, 1985; SNOW; HREBINIAK, 1980). Outros defendem alguma disciplina no campo, sobretudo, para facilitar o acúmulo de conhecimento, por meio da utilização sistemática de um conjunto de conceitos – e alternativas para sua operacionalização – razoavelmente aceito (VENKATRAMAN;
GRANT, 1986). Este artigo teve por objetivo revisitar o conceito de estratégia e seu uso corrente na administração, desde o seu uso específico, tais como em gestão estratégica de pessoas, estratégia de comunicação, ou sua aplicação geral, como no posicionamento organizacional, que é a alma, a personalidade, a razão de ser da empresa.

O objetivo deste trabalho é o de ampliar o entendimento sobre as percepções e opiniões dos alunos a respeito do ensino da Ética nas escolas de Administração. Com base em estudo junto a um grupo de alunos de curso de graduação em Administração de uma faculdade privada do Rio de Janeiro, buscou-se investigar: qual a concepção dos alunos sobre o termo Ética; qual a importância que eles atribuem ao estudo da Ética e como deve ser o ensino da Ética nas escolas de Administração. A revisão bibliográfica trata da definição deste constructo e das contribuições de estudos sobre o ensino da Ética em Administração. Para se atingir o
objetivo proposto, utilizou-se uma abordagem qualitativa, por meio de sete grupos focais, totalizando 74 participantes. Os resultados evidenciaram a importância que os alunos conferem ao ensino da Ética na faculdade de Administração, a ênfase em métodos de ensino participativo
em um ambiente favorável bem como as críticas ao enfoque dado pela faculdade ao ensino da Ética. As conclusões apontam caminhos para o ensino de Ética nas faculdades de Administração.
