A new type of “Third Place”?
Authors: Slater Alix , Jung Koo Hee 
Published: July 2010

PurposeThe purpose of this paper is to explore the notion of “Third Place” in an arts context by exploring the consumption of two arts venues, Tate Modern and the Southbank Centre (SBC) on the regenerated South Bank in London, UK.Design/methodology/approachAn interpretative phenomenological approach was taken drawing on 45 qualitative interviews that were conducted in and around Tate Modern and the SBC during Autumn 2009.FindingsFour audience groups were identified segmented by their motivations, experiences and feelings about the two buildings. The first group “Place to see” visit Tate Modern and the SBC to attend exhibitions and performances. The second meet friends and spend time in the cafes and bars using them as a “Place to hang‐out and meet”. The third group use the buildings as a “Place to drop‐in” on their way to somewhere else. The fourth group use the SBC as a “Third Place”, to study, for meetings, to read, escape and rejuvenate.Research limitations/implicationsThis was an exploratory paper. Further research is required to test the findings in other art museums, arts venues, libraries, parks and other public and private spaces within communities.Originality/valueThe paper fills a gap by drawing on the “Third Place” literature to explore the consumption of art museums and venues. It provides us with a better understanding of the meanings these public buildings have to individuals, the way they are used by the public and how arts managers might attract new audiences from their communities. It also provides insights for planners and town centre managers as to the types of places individuals are seeking during their daily lives.

It is now a place where community gathers, and enormous attention is given to staying in touch with the sentiment of the community. This has been achieved through effective strategic management, which has encouraged the community to play the part of creative leaders through the use of a number of key tactics.Originality/valueFederation Square has become a successful place thanks to the involvement of the community – the management of the square presents a model which other similar schemes could replicate/take pointers from.
“Shotgun partnership”: a Systems‐Centered™ case study analysis
Authors: Farrier Alan , Davis Rowena , Froggett Lynn , Poursanidou Konstantina 
Published: July 2010

PurposeThis case study aims to explore the relationship between identity and locality in two groups of young people from different environments working with a community artist to explore representations and perceptions about their environment, culminating in an exchange visit. The paper seeks to explore the challenges and complexities of partnership working in community regeneration in order to move beyond prevalent idealised views of partnership as a policy tool.Design/methodology/approachThe multi‐method qualitative evaluation included filming, direct observations of project sessions and interviews with key professionals. A systems analysis was then conducted using the Systems‐Centered® Training framework.FindingsThe extent to which multi‐agency partnerships in community regeneration are likely to be effective and sustainable is related to the development of the partnership systems. Shared goals, clear roles and a common understanding of the context of the collaborative work are critical for developing multi‐agency systems.Practical implicationsThe paper highlights the complex issues that need to be addressed when working with young people on issues of identity and territory. It also presents a systems viewpoint on partnership that has wider policy and practice implications for multi‐agency partnerships.Originality/valueDrawing on a systems‐centered perspective, the paper expands the conceptual understanding of multi‐agency partnerships to seeing such partnerships as dynamic living human systems, which can then be understood in terms of the variables that affect their functioning and effectiveness. This provides a tool for analysis and reflection on partnership that is of value to both academics/researchers and managers/practitioners.
Can international acquisition be an effective way to boost innovation in developing countries?
Authors: Liu Xielin 
Published: July 2010

PurposeThe purpose of this paper is to examine the effects of international acquisition activities on performance and its role in innovation build‐up in developing countries.Design/methodology/approachA case study was used to understand the deep integration process of acquisition process. The theory behind the study is the relationship of innovation management and merger and acquisition activities.FindingsAcquiring a company with higher technologies has more risks and it requires the acquiring company to master a fast learning capability. The key to a successful international technology acquisition for a developing country is to leverage technology dynamics and build up a high‐level learning capability to absorb tacit knowledge.Research limitations/implicationsAn in‐depth case study was adopted. Further quantitative research may be needed to test our research outcome here.Practical implicationsThe case study may provide valuable reference for the companies aiming to catch up via international acquisition in the developing countries.Originality/valueFirst, this paper is to enrich literature on acquisition research from a technological perspective. Second, fast learning capability, especially the capability to absorb tacit knowledge, is the key to a successful acquisition when a lagging‐behind company in the developing country wants to catch up a leading one.
The development strategy of electronic commerce in China
Authors: Ma Hui‐min , Meng Cheng‐cheng , Xiao Jun‐yong 
Published: July 2010

PurposeThe purpose of this paper is to explore e‐commerce development strategy from the consumer loyalty perspective in a Chinese context and to examine the impact of some key factors that affect e‐commerce development in China. The policy implications are also presented.Design/methodology/approachData were collected by the wide surveying of trained MBAs with different professional backgrounds. Confirmatory factor analysis and reliability analysis were then used to explore whether the “7C” model of consumer loyalty in electronic commerce is acceptable.FindingsThe results show that security and reputation have the most positive impact on consumer loyalty, and playfulness is not significantly related to the potential variable it belongs to. To those enterprises planning to implement e‐business in China, some advice is given; such as increasing the security and reputation of web sites and enhancing communications between buyers and sellers.Practical implicationsThe paper gives directions to the e‐commerce enterprises in developing countries about how to improve consumer loyalty and enhance business competence. Online enterprises can build consumer loyalty by improving their web sites and learning about consumers' behaviors to provide customized products and services. The specific policy measures in China are suggested.Originality/valueWhile it is known that consumer loyalty is critical to online enterprises' success, little is known about how to build and improve e‐loyalty in the emerging markets. This paper tries to bridge this gap by examining what affects e‐loyalty, to help better understand consumer loyalty in the emerging markets like China.

R&D and resource allocation capabilities can also significantly improve new product introduction.Research limitations/implicationsThe paper contributes to existing literature by studying the impact of TIC on innovation performance in HK. It also explores two out of seven TIC – R&D and resource allocation capabilities – to improve firms' innovation performance in the region.Originality/valueThis paper is one of very few that provide empirical evidence of the TIC and innovation performance in HK. It also revisits the audit framework proposed by recent innovation studies, which helps theoretical development.
STATISTICAL METHODS IN CERAMIC RESEARCH1
Authors: WESTMAN A. E. R. 
Published: July 2010

ABSTRACTIt is the fundamental object of ceramic research to build up a science of ceramics which will enable us to produce, in the most efficient manner and from a certain group of raw materials, finished products which will have prescribed sets of physical properties. In attempting to reach this objective, it is of importance that we develop new methods of research which are particularly fitted to solve our fundamental problems, and apply, as effectively as possible, the research methods which are now available. These research methods can be divided, on a working basis, into two classes, (1) exact methods in which the relationship existing between any two variables is determined by experiments in which the effects of all the other variables are rendered negligible by careful control of the experimental conditions, (2) statistical methods, which are used when it is impossible or impracticable to obtain such close control of the experimental conditions or when sampling errors are important and it is possible to repeat the experiments many times. It is the purpose of this paper to draw attention to the fact that we, as ceramists, have almost entirely neglected this second group of methods; to give a brief description, with examples, of some of the modern statistical methods, especially those used by the biometrists; and to point out a few of the situations in which these methods could be used to advantage in ceramic research, especially in investigations of refractory materials.
EFFECTS OF COMPOSITION ON THE PROPERTIES OF GROUND COAT ENAMELS FOR SHEET STEEL1
Authors: HARRISON W. N. , WOLFRAM H. G. 
Published: July 2010

ABSTRACTA series of ground coats was developed about each of three refractory bases, one of which consisted of flint and feldspar in a ratio frequently used commercially, another consisting of feldspar only, and the third of flint only. In each case the refractory portion was 58.5 parts of the whole. Besides the refractory, a “fixed addition” of 11.5 parts, comprised of 0.5 cobalt oxide, 1.0 manganese oxide, 5.0 boric oxide and 5.0 sodium oxide, was used in every enamel, bringing the basic constant portion for each series to 70 parts of the whole. The variable portion in each series was made up of equal parts of three constituents commonly used in enameling, chosen from a total of six in such a way that every possible combination was employed, making a total of twenty enamels in each series. All were given two cover coats of a standard white and tested for resistance to mechanical and thermal shock. In general the ingredients which were most conducive to resistance to the test treatments were flint in the refractory portion, and sodium oxide in the variable portion, constituted of fluxes. Also, boric oxide favorably influenced resistance to mechanical shock in the series containing both flint and feldspar. Resistance to mechanical and thermal shock in ground coats was considerably less affected by variations in expansivity than is the case in cover coats, the influence of that factor appearing to be partially obscured by other factors.
THE INFLUENCE OF DIFFERENT FELDSPARS ON THE “FREEZING” BEHAVIOR OF CONES1
Authors: Orton Edward , Krehbiel J. F. 
Published: July 2010

ABSTRACTThe term “freezing,” in ceramic parlance, means the increased resistance to viscous fusion, which ceramic bodies often show when their heat treatment is interrupted by chilling or the temperature is held static too long and not allowed to progress upward at the usual or proper rate. A body so treated often becomes distinctly more refractory and cannot be softened to viscous fusion without use of a higher temperature than would otherwise have been necessary. In this condition, it is said to be “frozen.” This freezing behavior may occur in the firing of cones as in other ceramic products, and, because of the use to which they are put and their shape which facilitates accurate comparisons, is more serious in its consequences and more easily detected than in other ceramic products.The present study was undertaken (a) to get some definite quantitative measurements of just what this lag in fusion amounts to under a given set of conditions, (b) to determine whether it is a peculiarity due to some one ingredient or combination of ingredients, or whether it is a generic quality applying to all ceramic mixtures of a given range, and (c) to get any new light that could be had as to the ultimate nature or cause of the phenomenon.The amount of the lag has been quantitatively determined for cone 10 as furnished by the Germans and our own factory, and the influence of different feldspars and clays in producing this lag has been experimentally studied. Different feldspars are shown to produce characteristic effects. No important light is thrown upon the ultimate cause of the phenomenon.
THE EFFECT OF TEMPERATURE ON THE OPTICAL PROPERTIES OF KAOLINITE1
Authors: McVay T. N. 
Published: July 2010

ABSTRACTEuhedral crystals of kaolinite sere heated to various temperatures, draw trials made at frequent intervals, and the effect of temperature was studied microscopically. The results obtained indicate three classes of kaolinite: (1) the natural kaolinite, (2) the uniaxial form produced at 625°C, the metanacrite of Rinne, and (3) the change of the metanacrite into what is probably mullite and glass at 1450°C.

PHYSICAL AND CHEMICAL PROPERTIES OF OILS AND PROBLEMS OF THEIR REMOVAL1
Authors: Guernsey F. H. 
Published: July 2010

ABSTRACTTool lubrication in sheet metal working is principally a matter of rapid development of a stable but deformable film. Viscosity is of lesser importance. Structure of the film is more important than thickness. Removal problems involve neutralization, wetting, emulsification, and direct counter colloidal pull to disrupt and disperse the film completely. Free rinsing of detergents and suspensions is necessary.

MINERALOGY OF TYPICAL NORTH CAROLINA CLAYS AND SHALES*
Authors: Fabianic W. L. , Stoltb N. H. 
Published: July 2010

ABSTRACTA microscopic examination was made on those clays and shales of North Carolina which gave most promise of future development in the structural clay products industry. The more common minerals were determined rather than the rare ones which did not occur in sufficient quantity to affect the quality of the clay. The work showed clay substance to be the most abundant material present, followed by quartz, red and yellow iron oxides, muscovite through sericite to hydromica, and epidote, with smaller amounts of rutile, biotite, titanite, tourmaline, and zircon. Diatoms were found in two cases and kaolinite in one.
CONSTITUTION AND THERMAL EXPANSION OF SILICA COKE‐OVEN BRICK AFTER SERVICE*
Authors: Austin J. B. , Piercs R. H. H. 
Published: July 2010

ABSTRACTTwo silica brick which were in service in a coke oven for over ten years have been examined under the petrographic microscope. At the flue side the brick were almost completely converted to cristobalite, next comes a relatively thick layer which is mainly tridyinite, and finally mar the coke side quartz is found in addition. Measurements on small specimens taken from one of the brick show that the several layers have very different expanions. I t is concluded that in cooling a battery of ovens great care should be taken to cool slowly through the temperature range 200 to 300deg;C.
SELENIUM RUBY GLASS: PREPARATION AND X‐RAY STUDY*
Authors: Bigelow Maurice H , Silverman Alexander 
Published: July 2010

ABSTRACTA study has been made of color produced by selenium and accessory substances in sodium oxide‐zinc oxide‐silica glasses. Most desirable reds were obtained by adding selenium, cadmium sulfide, arsenic trioxide, and carbon to a foundation batch. X‐ray examination indicates that the red color produced is probably due to a solid solution of CdS in CdSe.

EFFECT OF ZINC OXIDE ON SHEET‐IRON COVER‐ENAMEL PROPERTIES*
Authors: Fetterolf L D 
Published: July 2010

ABSTRACTThe effect of ZnO on sheet‐iron cover‐enamel properties was studied by evaluation of the propcrties of a typical sheet‐iron cover enamel in which ZnO was used as single‐ and double‐partial replacements for the various ingredients. The fluxing action of ZnO was found to bc pronounced and i i was markedly effective in decreasing frit solubility in the mill liquor. Improvement in gloss resulted from its use without any adverse effect on enamel extensibility and resistance to thermal shock.
COLOR CHANGES IN FLINT GLASS*
Authors: Lyle A. K. , Sharp Donald E. 
Published: July 2010

ABSTRACTDecolorized glasses vary in their approach to neutral color depending upon their use and custom of manufacture. Iron, the chief coloring agent in colorless glass, produces several colors. The iron color is first controlled and then neutralized with its complementary color or colors furnished by a variety of oxides. The final tint may be neutral or not, depending upon the method of examination, and varies with changing conditions.The decolorizing materials are subject to change after the glass is made. These changes are caused by heat and light radiations. Much research on color change is incomplete. The glass composition should be accurately known and the color should be represented by spectral transmissions.
A PECULIARITY OF SHEET‐IRON ACID RESISTING COVER COAT ENAMELS*
Authors: Ebright H. E. , Hansen J. E. 
Published: July 2010

ABSTRACTIt has been demonstrated that the small bare spots evident in the first coat of acid‐resisting enamel applied directly upon the ground coat are not necessarily the result of a process fish scaling in the ground coat during the firing operation, but are more often the result of reboiling of the ground‐coat enamel and lack of film strength in the yet unfused layer of acid‐resisting enamel. Reboiling, or other mechanical movements of the ground coat, may promote defects in acid‐resisting enamels which would not be visible in those of the nonacid‐resisting type, particularly when these enamels are applied directly upon the ground coat. The electrolytes used with acid‐resisting enamels are directly connected with the popping condition noted. A choice of the proper kinds and amounts of electrolytes for “setting‐up” the enamel can, in some cases, eliminate or minimize this trouble. The use of a nonacid‐resisting enamel, properly set up as an intermediate layer between the ground coat and the finish coat of acid‐resisting enamel, will also prevent troubles of this kind. The tendency for this peculiar defect to occur depends also upon the type of enameling base metal used and its tendency to reboil.
NOTES ON THE X‐RAY DIFFRACTION PATTERNS OF MULLITE*
Authors: Posnjak E. , Greig J. W. 
Published: July 2010

ABSTRACTA wide range of artificial alumina‐silica products has been examined by the X‐ray powder method. In each case in which the pattern has been sufficiently clear to permita decision the pattern has been that of mullite, not that of sillimanite. The examination included a number of preparations made by heating clay minerals and clays at 1000°.Mullite crystals containing alumina or the oxides of iron or titanium in solid solution give diffraction patterns in which the lines are slightly displaced toward the origin with respect to the corresponding lines in the diffraction pattern of the standard mullite (3A12O3.2SiO2).Mullite crystals, freed by HF treatment from the matrix in which they grew, often give diffraction patterns in which the intensities of certain lines are strikingly different from normal. This is due to the orientation of the minute elongated crystals when mounted for photographing.Finally, two recent papers proposing special names for certain similar materials are discussed and, on the basis of published data and the evidence presented here, these proposals are found to be unwarranted.
