Questioning the Universality of Institutional Transformation Theories in Spatial Planning: Shopping Mall Developments in Palermo

Theories about institutional transformation in spatial planning, although mainly based on the Anglo-Saxon context, have assumed a dominant role in planning research and theory as means to understand the transformations that have been restructuring planning systems in recent decades in the Western world and beyond. The article, looking at transformations of planning practice through the lenses of the concept of planning cultures, debates the utility of building ‘universal’ theories for spatial planning and advocates for the need for a de-provincialization of planning theories. This is done through a case-study approach applied to the history of the transformation of the retail system in a context characterized by the specificities of the Italian planning context and Southern European cities, namely: the planning processes for, and power relationships underlying, the first shopping malls opened in Palermo, Italy, since 2009 — some decades later than most of Western cities.

Reallocation of resources between the tradable and non-tradable sector in Portugal: Assessing the degree of structural transformation in the Portuguese economy

Portugal implemented a large number of structural reforms in the recent years, which are expected to enhance the allocation of resources in the economy, namely from the non-tradable to tradable sector. We argue that the methodology to identify the tradable sector used by some international institutions is outdated and may hamper an accurate assessment of the progress achieved so far. Based on an enhanced methodology to identify the tradable sector, we are able to provide a more accurate, clearer picture of the recent structural developments of the Portuguese economy.

Stages of organizational transformation in transition economies: A dynamic capabilities approach

How do organizations previously dominated by the state develop dynamic capabilities that would support their growth in a competitive market economy? We develop a theoretical framework of organizational transformation that explains the processes by which organizations learn and develop dynamic capabilities in transition economies. Specifically, the framework theorizes about the importance of, and inter-relationships between, leadership, organizational learning, dynamic capabilities, and performance over three stages of transformation. Propositions derived from this framework explain the pre-conditions enabling organizational learning, the linkages between types of learning and functions of dynamic capabilities, and the feedback from dynamic capabilities to organizational learning that allows firms in transition economies to regain their footing and build long-term competitive advantage. We focus on transition contexts, where these processes have been magnified and thus offer new insights into strategizing in radically altered environments.

Review: intellectual property aspects of plant transformation

One of the recurring themes of the debates concerning the application of genetic transformation technology has been the role of Intellectual Property Rights (IPR). This term covers both the content of patents and the confidential expertise usually related to methodology and referred to as 'Trade Secrets'. This review explains the concepts behind patent protection, and discusses the wide-ranging scope of existing patents that cover all aspects of transgenic technology, from selectable markers and novel promoters to methods of gene introduction. Although few of the patents in this area have any real commercial value, there are a small number of key patents that restrict the 'freedom to operate' of new companies seeking to exploit the methods. Over the last 20 years, these restrictions have forced extensive cross-licensing between ag-biotech companies and have been one of the driving forces behind the consolidation of these companies. Although such issues are often considered of little interest to the academic scientist working in the public sector, they are of great importance in any discussion of the role of 'public-good breeding' and of the relationship between the public and private sectors.

Use of in situ FT-Raman spectroscopy to study the kinetics of the transformation of carbamazepine polymorphs

The solid-state transformation of carbamazepine from form III to form I was examined by Fourier Transform Raman spectroscopy. Using a novel environmental chamber, the isothermal conversion was monitored in situ at 130◦C, 138◦C, 140◦C and 150◦C. The rate of transformation was monitored by taking the relative intensities of peaks arising from two C H bending modes; this approach minimised errors due to thermal artefacts and variations in power intensities or scattering efficiencies from the samples in which crystal habit changed from a characteristic prism morphology (form III) to whiskers (form I). The solid-state transformation at the different temperatures was fitted to various solid-state kinetic models of which four gave good fits, thus indicating the complexity of the process which is known to occur via a solid–gas–solid mechanism. Arrhenius plots from the kinetic models yielded activation energies from 344 kJ mol−1 to 368 kJ mol−1 for the transformation. The study demonstrates the value of a rapid in situ analysis of drug polymorphic type which can be of value for at-line in-process control.

Study of phase transformation and work hardening phenomenon during drilling of Ti-5553 and Ti-64

Titanium 5553 is a recently developed modification of Russian near-β titanium alloy VT-22 which has applications and potential particularly in the aerospace industry for such key components as landing gear. However, indications are that Ti-5553 has poorer machinability characteristics than other Ti alloys and a comprehensive and far-reaching analysis is a necessary research imperative. This paper presents the result of phase transformation and work hardening during drilling of Ti-5553 compared with Ti-64. The aim of this research work is to optimise the machining condition for Ti-5553, in which the β to a phase transformation, together with material work hardening could be fully understood. Analysis of machinability indicators, such as subsurface micrograph and hardness of drilled samples and drilling forces and torques, demonstrated that Ti-5553 generally has poorer machinability characteristics than Ti-64 and to some extent this variation has been quantified to allow for further and more detailed investigation.

Experiment and theoretical prediction of martensitic transformation crystallography in a Ni–Mn–Ga ferromagnetic shape memory alloy

A detailed study of martensitic transformation crystallography and microstructural characteristics in the Ni53Mn25Ga22 ferromagnetic shape memory alloy (FSMA) was performed by both experimental observation and theoretical calculation. It is revealed that there are two microscopically twin-related martensitic variants with a misorientation of ∼82° around the 〈1 1 0〉_M axis in each initial austenite grain. The twin interface plane was determined to be {0.399 0.383 0.833}_M (1.79° away from {1 1 2}_M). The ratio of the amounts of the two variants inherited from one single austenite grain is about 1.70. The prevalent orientation relationship between austenite and martensite was found to be Kurdjumov–Sachs (K–S) relationship with (1 1 1)_A//(1 0 1)_M, [110]A//[111]_M. A successful explanation of the crystallographic features during martensitic transformation will shed light on the development of FSMAs with optimal performance.

MidiCities : test beds for innovative delivery of urban transformation

Cities globally and nationally are facing a range of daunting challenges to respond to a suite of emerging imperatives including a low carbon future, oil vulnerability, demographic re-composition, and the prospect of unpredictable economic shocks. To pursue a future that is sustainable and resilient requires substantial transformation of existing urban areas and creation of new mechanisms to guide and manage delivery of physical, economic and social changes.

Mid-sized cities provide legible, nimble test beds for exploring cross-disciplinary models and innovative governance and delivery techniques. Australia’s ‘MidiCities’ – home to 4 million urban dwellers frequently overlooked by urban policy or research effort – are emerging as crucibles of innovation and experimentation. Most of these cities retain that essential key ingredient for sustainable urbanism, economic resilience and community identity: a strong, highly legible city centre with a tightly clustered diversity of facilities and functions – the multi-functional activity centre that metropolitan suburban hubs yearn to grow up to become!

These diverse MidiCities are passing a threshold of self-confident sophistication, and are now providing valuable lessons for each other, which could be adopted or adapted by metropolitan cities where scale and complexity can often overwhelm the search for new and appropriate approaches to delivery of rapid change while maintaining clear guidance toward the vision of a ‘preferred’ future. A network of professionals working with Australian and New Zealand MidiCities is coalescing toward a cross-disciplinary platform for exchange of experiences and information, mutual support, improved research and understanding, capacity-building and the refinement of new specialist skills and structures.

Phase and crystal orientation study of a TRansformation Induced Plasticity steel subjected to cyclic load induced fatigue

An electron backscatter diffraction (EBSD) study of the microstructure of TRIP steel during fatigue failure. Phase and crystal orientation study of a TRIP steel subjected to cyclic load induced fatigue. The relative fractions of austenite, ferrite and martensite are quantified within the strain field of a fatigue crack tip. This data is a subset of data supporting a wider study of the fatigue properties of multiphase steels used in the automotive industry. The different microstructural phases present in these steels can influence the strain life and cyclic stabilized strength of the material due to the way in which these phases accommodate the applied cyclic strain. Fully reversed strain-controlled low-cycle fatigue tests have been used to determine the mechanical fatigue performance of a dual-phase (DP) 590 and transformation induced plasticity (TRIP) 780 steel, with transmission electron microscopy (TEM) and scanning electron microscopy (SEM-EBSD) used to examine the deformed microstructures .
