Urban and suburban grids should be flexible, and adaptable to historic changes. The Kagome net is compared with a Cartesian and a polar one, and in three dimensions a cuboctahedral/cubic space frame is compared with an orthogonal one and with an octet frame. The interactions between demographic distributions and geometry generated a cybernetic system in which changes in one constantly engender forces which in turn modify the other.

In this paper an extensive study is reported of the very remarkable, and thus far apparently unique, case of the deformation in three dimensions of protocatechuic acid, to which attention was drawn many years ago by Otto Lehmann. The deformations are spontaneous, and are probably due to progressive gliding of the lattice planes, which exist in two configurations, one stable and the other unstable, the latter being the condition of the long prismatic rods when they first form. Such a prism presently deforms into a zigzag crystal, with stable and unstable sections in alternation which, with continuation of the deformation, becomes again straight, but now in the stable configuration. The bending is progressive, like that of an umbrella case, pendant from the end of an oblique cane pointed down, when the latter is pushed into it. The movements are so rapid that motion pictures, made with a microscope, were necessary for the observation of certain stages of the deformation. The deformations have been shown to many chemists and physicists during the past decade or more, none of whom had ever seen or heard of this remarkable type of crystal movement. The deformations are usually observed as the warm saturated solution cools, but they also occur after the crystal has been dried for many hours.

Nowadays, mobile phones provide not just voice call and messaging services, but plethora of other services. Those computational capabilities allow mobile phones to serve people in various areas including education, banking, commerce, travelling, and other daily life aspects. Meanwhile, the number of mobile phone users has increased dramatically in the last decade. On the other hand, the usability of an application can usually be verified through the user interface. Therefore, this paper aims to design a measurement tool to evaluate the usability of mobile applications based on the usability attributes and dimensions that must be considered in the interface. To obtain the appropriate attributes, a Systematic Literature Review (SLR) has been conducted and the Goal Question Metric (GQM) has been used to design the tool. From 261 related works only 18 most relevant ones were selected, through four SLR. 25 dimensions were found through the SLR, but some of these dimensions are synonymous or a part of other dimensions. Consequently, three dimensions must be included in any usability evaluation instrument, which is broken down into ten sub dimensions.

Purpose Although the literature has established the effect of online reviews on customer purchase intentions, the influence of psychological factors on online ratings is overlooked. This paper aims to examine these factors under the perspective of construal level theory (CLT). Design/methodology/approach Using review data from TripAdvisor and Booking.com, the authors study three dimensions of psychological distances (temporal, spatial and social) and their direct and interaction effects on review valence, using regression analysis. The authors examine the effect of these distances on the information content of online reviews using a novel bag-of-words model to assess its concreteness. Findings Temporal distance and spatial distance have positive direct effects on review valence. Social distance, on the other hand, has a negative direct effect. However, its interaction with the other two distances has a positive effect, suggesting that consumers tend to “zoom-out” to less concrete things in their ratings. Practical implications The findings provide implications for the interpretation of review ratings by the service providers and their information content. Originality/value This study extends the CLT and electronic word-of-mouth literature by jointly exploring the effect of all three psychological distances that are applicable in post-purchase evaluations. Methodologically, it provides a novel application of the bag-of-words model in evaluating the concreteness of online reviews.

The presence of contemporary entities in the cyber-space shows that IT offers unlimited possibilities of running a business and developing an organisation. On the other hand, it involves a greater number of internal and external threats in the area of accounting information resources security. The objective of the paper is to diagnose the current level of accounting information resources security (AIRS) assurance in Polish business entities. The paper analyses two research hypotheses. In accordance with the first one, the AIRS assurance level in various entity groups may be different, even though all entities should have implemented the same requirements of the Accounting Act in the analyzed area. The identified differences may result from the effect of additional, industry-specific regulations. The other hypothesis claims that in the private business area, accounting and auditing companies adhere to AIRS regulations more strictly than other small and medium enterprises. The paper defines the fundamental factors affecting the functioning of corporate accounting systems in the three dimensions of the cyber-space. Subsequently, the author presents the results of empirical research on how corporate information security is ensured in the context of internal accounting control systems and the requirements of the Polish Accounting Act. The results of the empirical research show how the management of the analysed entities crafts the basic elements of their internal environment as well as internal communication and control processes connected with ensuring information resources security. The results also show the management’s approach to various aspects of risk management of accounting information resources security, as well as to adherence to organisational and administrative procedures, and to hardware and software safeguards in the IT environment of the accounting system. The issues analysed in the present paper open a scholarly discussion that should lead to the development of theoretical models, recommendation of efficient methods and tools, as well as indication of adequate legislative initiatives. Research methods used by the author include analysis of literature and legislation, analysis of survey results, deduction and inference.

The Impact

This research explored the impact of job satisfaction, the ethical behavior of coworkers, successful managers, and employees themselves. Also explored were six types of ethical climate on organizational commitment and its three dimensions, including affective, continuance, and normative commitment through an investigation on 476 Chinese insurance agents. The empirical results showed that ethical behavior of coworkers and a caring climate had a significantly positive impact on both organizational commitment and its three dimensions, while independence climate had no significant influence on overall organizational commitment or its three dimensions. Job satisfaction, ethical behavior of successful managers and employees themselves, and the other five types of ethical climates only had a significant impact on organizational commitment or some of its dimensions.

The Relationship

The fields of frugal and reverse innovation as well as sustainability and its management have received tremendous interest in recent times. However, there is little literature on how both fields are related to each other. Hence, this paper gives an overview of research in both areas and provides a view of the relationship between frugal and reverse innovation, sustainability management and performance constructs. The link between frugal and reverse innovation on the one hand and sustainability performance on the other hand is established through a differentiated perspective on dimensions representing different fields of sustainability management, i.e. the sustainability of resources used in value creation, the sustainability of the actual value creation processes, and the sustainability of the outcomes of value creation processes. Moreover, we also argue for a positive link between the three dimensions of sustainability management and a company’s market performance.

AbstractWe study an $$SO(2)\times SO(2)\times SO(2)\times SO(2)$$ S O ( 2 ) × S O ( 2 ) × S O ( 2 ) × S O ( 2 ) truncation of four-dimensional $$N=4$$ N = 4 gauged supergravity coupled to six vector multiplets with $$SO(4)\times SO(4)$$ S O ( 4 ) × S O ( 4 ) gauge group and find a new class of holographic RG flows and supersymmetric Janus solutions. In this truncation, there is a unique $$N=4$$ N = 4 supersymmetric $$AdS_4$$ A d S 4 vacuum dual to an $$N=4$$ N = 4 SCFT in three dimensions. In the presence of the axion, the RG flows generally preserve $$N=2$$ N = 2 supersymmetry while the supersymmetry is enhanced to $$N=4$$ N = 4 for vanishing axion. We find solutions interpolating between the $$AdS_4$$ A d S 4 vacuum and singular geometries with different residual symmetries. We also show that all the singularities are physically acceptable within the framework of four-dimensional gauged supergravity. Accordingly, the solutions are holographically dual to RG flows from the $$N=4$$ N = 4 SCFT to a number of non-conformal phases in the IR. We also find $$N=4$$ N = 4 and $$N=2$$ N = 2 Janus solutions with $$SO(4)\times SO(4)$$ S O ( 4 ) × S O ( 4 ) and $$SO(2)\times SO(2)\times SO(3)\times SO(2)$$ S O ( 2 ) × S O ( 2 ) × S O ( 3 ) × S O ( 2 ) symmetries, respectively. The former is obtained from a truncation of all scalars from vector multiplets and can be regarded as a solution of pure $$N=4$$ N = 4 gauged supergravity. On the other hand, the latter is a genuine solution of the full matter-coupled theory. These solutions describe conformal interfaces in the $$N=4$$ N = 4 SCFT with $$N=(4,0)$$ N = ( 4 , 0 ) and $$N=(2,0)$$ N = ( 2 , 0 ) supersymmetries.

AbstractThis paper examines judicial leadership on the UK Supreme Court. It does not confine itself to the formal roles of the President and Deputy President. Rather, building on existing categories of judicial leadership, including administrative, jurisprudential and community leadership, it considers the contributions of all 12 Justices. In so doing, it provides a significant compilation of quantitative data on the activities of the Justices of the Supreme Court both on and off the bench from the the Court's inception in 2009 to the end of the 2014-2015 legal year. From this, we suggest that while a number of the Justices engaged in one or two broad forms of leadership – with Lady Hale in particular demonstrating a substantial degree of leadership across all three dimensions – at the other end of the spectrum, at least on the measures used in this paper, a significant minority did not. In the light of this, and the significant number of recent and forthcoming retirements from the Court, the paper concludes by considering the implications of our findings for the future of the Court. We argue that these retirements will result in gaps in both formal and informal judicial leadership, and it is vital that these gaps are filled by appointees who are capable of, and prepared to step up to, diverse and varied forms of judicial leadership.

The purpose of this study is to examine and to explore the influence of website navigational design as a part of ICT, on decision to choose off road adventure service provider, as a sport tourism provider. The sample is 125 companies from varieties of type and category, by using purposive sampling. Data collected through literature review, observation and questionnaires. Path analysis is used as a data analysis technique with SPSS 20. Results shows that only search options influenced decision to choose off road adventure service provider. The other three dimensions don’t have influence in decision to choose off road adventure service provider. It shows that majority of people use website only to find information and tend to see navigation bar, individual hyperlink and image maps as not important. This means that the level of website literacy among consumer is still low. It is important for companies to educate their consumers on how website could benefit them.

Laminate Thickness

A computational model is developed to predict the performance of phase change materials(PCMs) for passive thermal control of electronic modules during transient power variations or following an active cooling system failure. Two different ways of incorporating PCM in the module are considered. One is to place a laminate of PCM outside the multichip module, and the other is to place the PCM laminate between the substrate and the cold plate. Two different types of PCMs are considered. One is n-Eicosene, which is an organic paraffin, and the other one is a eutectic alloy of Bi/Pb/Sn/In. Computations are performed in three dimensions using a finite volume method. A single domain fixed grid enthalpy porosity method is used to model the effects of phase change. Effects of natural convection on the performance of PCM are also examined. Results are presented in the form of time-wise variations of maximum module temperature, isotherm contours, velocity vectors, and melt front locations. Effects of PCM laminate thickness and power levels are studied to assess the amount of PCM required for a particular power level. The results show that the PCMs are an effective option for passive cooling of high density electronic modules for transient periods.
