description: A characteristic feature of the state-of-the-art of real-space methods in electronic structure calculations is the diversity of the techniques used in the discretization of the relevant partial differential equations. In this context, the main approaches include finite-difference methods, various types of finite-elements and wavelets. This paper reports on the results of several code development projects that approach problems related to the electronic structure using these three different discretization methods. We review the ideas behind these methods, give examples of their applications, and discuss their similarities and differences.

description: We investigate the star formation histories (SFHs) of massive red spiral galaxies with stellar mass $M_\ast>10^{10.5}M_\odot$, and make comparisons with blue spirals and red ellipticals of similar masses. We make use of the integral field spectroscopy from the SDSS-IV/DR15 MaNGA sample, and estimate spatially resolved SFHs and stellar population properties of each galaxy by applying a Bayesian spectral fitting code to the MaNGA spectra. We find that both red spirals and red ellipticals have experienced only one major star formation episode at early times, and the result is independent of the adopted SFH model. On average, more than half of their stellar masses were formed $>$10 Gyrs ago, and more than 90\% were formed $>6$ Gyrs ago. The two types of galaxies show similarly flat profiles in a variety of stellar population parameters: old stellar ages indicated by $D4000$ (the spectral break at around 4000Å), high stellar metallicities, large Mgb/Fe ratios indicating fast formation, and little stellar dust attenuation. In contrast, although blue spirals also formed their central regions $>$10 Gyrs ago, both their central regions and outer disks continuously form stars over a long timescale. Our results imply that, massive red spirals are likely to share some common processes of formation (and possibly quenching) with massive red ellipticals in the sense that both types were formed at $z > 2$ through a fast formation process.Possible mechanisms for the formation and quenching of massive red spirals are discussed.

description: This paper uses a simulation model to measure the size of the social welfare gains from price stabilisation within the general setting of a non-linear, multiplicative risk and lagged expectations model of the market. The size of the gains is found to be relatively small when producers plan on the basis of rational expectations, but it can be quite substantial for other types of expectations behaviour, including those commonly assumed in empirical supply analysis. We conclude that, in many cases, improved market information services may more economically provide the substantial part of the social benefits of price stabilisation.

description: We investigate the supervised machine learning of few interacting bosons in optical speckle disorder via artificial neural networks. The learning curve shows an approximately universal power-law scaling for different particle numbers and for different interaction strengths. We introduce a network architecture that can be trained and tested on heterogeneous datasets including different particle numbers. This network provides accurate predictions for all system sizes included in the training set and, by design, is suitable to attempt extrapolations to (computationally challenging) larger sizes. Notably, a novel transfer-learning strategy is implemented, whereby the learning of the larger systems is substantially accelerated and made consistently accurate by including in the training set many small-size instances.

description: Visual research has been gaining in importance in recent years. This can be seen most clearly in those methods that rely on various forms of visual representation and using photographs, films, or videos as main sources of data. While opening the door to a deeper understanding and interpretation of social realities, visual analysis continues to deliver methodological challenge to the social sciences. This article sheds light on the development of visual analysis and focuses on its relevance for social research. Starting with its first applications following the invention of still and moving cameras, it traces this development up to the current use of audio-visual digital camera technologies in social research, which has made the most noticeable theoretical and methodological progress in the social sciences in the fields of videography and interpretive video analysis.

Taxation and Consumption of Wine

Subjects: Food Consumption/Nutrition/Food Safety

description: In this article, the impact that a sales tax might have upon wine consumption and, hence, on the wine and grape growing industries, is analysed. Implications for government revenue are also considered. It is shown that the relative responsiveness of supply and demand, rather than the level in the marketing chain at which a tax is levied, determines where the tax burden finally falls. The imposition of a tax on wine might force certain sectors of the wine and grape industries to undergo a phase of adjustment. However, over the longer term, a tax would not necessarily alter the impact of other factors affecting the demand for wine. Additional taxes on wine of the form of a 10 per cent sales tax could be expected to increase government revenue from all indirect taxes by about 1 per cent.

description: The exact nondipole minimal-coupling Hamiltonian for an atom interacting with an explicitly time- and space-dependent laser field is transformed into the rest frame of a classical free electron in the laser field, i.e., into the Kramers-Henneberger frame. The new form of the Hamiltonian is used to study nondipole effects in the high-intensity, high-frequency regime. Fully three dimensional nondipole {\it ab initio} wavepacket calculations show that the ionization probability may decrease for increasing field strength. We identify a unique signature for the onset of this dynamical stabilization effect in the photoelectron spectrum.

Changes in Rural Land Use and Part-time Farming, Central Victoria, 1974 to 1978

Subjects: Land Economics/Use

description: Successive surveys of 376 rural holdings near Melbourne, in 1974-75 and 1978-79, revealed a substantial increase in part-time farming at the expense of full-time farming, but little change in overall land use and area farmed. Few of the part-time farms surveyed were profitable in the mid-1970's, but most farmers put their farming way of life ahead of financial considerations, and the blow was softened by capital gains on farm land and the tax deductibility of farm losses. Part-time farms were a little less productive than neighbouring full-time farms, but there was little evidence that small part-time farms were neglected or badly managed. In any case, the relative insignificance of small holdings in the survey areas suggests that concern about the adverse land-use consequences of "hobby farms" and "rural retreats" may be overstated.

The Factual Treatment of Actuality: The Emergence of Educational Film in the 1920s and its Relation to Documentary Film Proper
Creators: name: Ahnert, Laurel E.
Publisher: name: InterDisciplines. Journal of History and Sociology
Year: 2013

description: This paper looks at the relatively unexamined relationship between so-called educational films of the 1920s and films of the 1930s American and British Documentary Film Movement, which includes such canonized works as The City (Ralph Steiner and Willard Van Dyke, 1939) and The Plough That Broke the Plains (Pare Lorentz, 1936). Rather than seeing a historical break between nonfiction films of the pre- and post-sound era, this paper argues that the 1920s served as a kind of gestational period for the renaissance of documentary films that would occur during the 1930s and 1940s. It is the discursive, institutional, and exhibition contexts of early educational film that establishes the foundation for later documentaries, while simultaneously allowing for slippages in how society understood the changing purpose and possibilities of cinema during the period. To make this argument, this paper uses as its primary case study a series of films made in the early 1920s that were produced through a partnership between the Illinois state government and the dairy industry and exhibited in a range of venues from state fairs to classrooms. These films demonstrate the fluidity between early, simple educational films and their supposedly more complex descendants lauded by the film studies discipline.

FARMERS' DECISION PROCESSES AND ADOPTION OF CONSERVATION TILLAGE

Subjects: Crop Production/Industries

description: In a transect survey of crop residue levels in 1995 and 1996, two Minnesota counties had very different percentages of cropland with desired residue cover even though the soil types were similar. To gain a better understanding of the reasons behind this difference, the farmers in these two counties were surveyed about their use or lack of use of conservation tillage practices. A statistical logit analysis of survey responses showed farmers are more apt to adopt conservation tillage if they are larger; are more concerned about erosion on their land; have made a recent major investment in the farm; use other producers for tillage information; have the management skill for conservation tillage; and believe conservation tillage will fit with their production goals and the physical setting of their farm. Two counterintuitive findings are the negative effects of the ease of finding information and the degree of control of the adoption decision. The costs and labor requirements of conservation tillage were important but not as statistically significant as those factors just listed. Some variables, that are often listed as potentially important factors, were not found to be important in this survey. These included the long-term viability of the farm; the age, education, and experience of the farmer; the debt level of the farm; whether a family member wanted to continue farming; the proportion of land rented; the use of other sources for tillage information; the complexity of conservation tillage practices; the producer's planning horizon; the risk of negative returns; the availability of support for conservation tillage systems; and the quality of conservation tillage information.
Documentary Film in Media Transformation
Creators: name: Weber, Thomas
Publisher: name: InterDisciplines. Journal of History and Sociology
Year: 2013

description: My contribution focuses on the difficulty of defining and classifying the various forms of the documentary film in different media environments. My argument consists of three central points:

1. An essentialist definition of the documentary (for example as the opposite of fictional film) leads us into a trap, as this kind of definition is closely linked to the idea of an inherent structure underlying all documentary films. Hence, this creates misunderstandings, or insufficient notions such as »hybridization.«

2. In the theoretical discourse on documentary film, we can observe a shift from essentialist definitions to observations of procedures of reading, producing or even distributing the documentary. These procedures also mark a difference to fictional genres.

3. The central criterion for the documentary is the stability of its reference to reality. Therefore, the most obvious way to classify the different forms of documentary films is an analysis of the variance of this stability due to the play of various actors in different milieus.

Electromigration theory unified

description: The starting formula of Bosvieux and Friedel for the force on an ion in a metal due to an applied voltage is shown to lead to the same description as the linear-response approach used in the field since its introduction by Kumar and Sorbello. By this electromigration theory has become a unified theory. It follows after accounting for a treacherous trap term, which at first sight seems to be zero. Up to now Bosvieux and Friedel claimed to predict a completely screened direct force, which means that only a wind force would be operative. In addition the amount of screening has been calculated up to second order in the potential of the migrating impurity, using a finite temperature version of the screening term derived by Sham. For a proton in a metal modeled as a jellium the screening appears to be about 15%, which is neither negligible nor reconcilable with the old full-screening point of view.

What helps and what hinders in cross-cultural supervision : a critical incident study
Creators: name: Wong, Lilian Chui Jan
Publisher: name: University of British Columbia
Year: 2009

description: The present study investigated what helped and what hindered multicultural supervision. The participants consisted of 19 females, and 6 males, including Asian-Canadians, Indo- Canadians, First Nations, Latin-Canadian and Afro-Canadian. They were individually interviewed, following an expanded version of Flanagan's (1954) Critical Incident Technique. There were 340 relevant meaning units related to positive incidents and 386 meaning units related to negative incidents. Forty-two meaning units were associated with coping efforts, and 87 meaning units were on recommendations. Categories extracted from these meaning units were grouped as follows: (a) 20 positive categories, (b) 15 negative categories, (c) 15 coping categories, and (d) 33 recommendations. The reliability of classifying meaning units according to these categories was satisfactory, based on inter-judge agreement (80% and higher). The validity of content analysis was established by (a) confirmation by participants, (b) crossvalidation by other participants, (c) cross-validation by an independent judge, and (d) cross-validation by other researchers. The most frequently cited positive categories were subsumed under five key areas: (a) personal attributes of the supervisor, (b) supervision competencies, (c) mentoring, (d) relationship, and (e) multicultural supervision competencies. The most frequently reported negative categories were associated with the following five areas: (a) personal difficulties as a visible minority, (b) negative personal attributes of the supervisor, (c) lack of a safe and trusting relationship, (d) lack of multicultural supervision competencies, and (e) lack of supervision competencies. The coping efforts employed were grouped into four areas: (a) help seeking, (b) existential coping, (c) active coping, and (d) emotional coping. Finally, recommendations were also grouped into four broad areas: (a) needs to improve the quality of supervision, (b) needs to improve multicultural supervision competencies, (c) needs for educational institutions to make changes, and (d) needs for minority students to make changes. The study provided a comprehensive picture of what works and what does not work in multicultural supervision. The results support a mentoring model, which posits that supervision is effective to the extent that the supervisor takes on the role of a mentor. The practical implications of the study include the need for cross-cultural supervision competencies and mentoring graduate students.

description: Stimulated by recent experimental observation of $X_1(2900)$ just below the $\bar D_1K$ threshold, we extend our previous study of $\bar D_1D$ S-wave bound state by vector meson exchange to $\bar D_1K$ system as well as similar $\bar DK_1$, $D_1K$ and $DK_1$ systems to look for possible bound states. We find that the potential of $D K_1$ is attractive and strong enough to form bound states with mass around 3110 MeV for $DK_1(1270)$ and 3240 MeV for $DK_1(1400)$. $D_1 K$ is also attractive but weaker, hardly enough to form bound states. While $\bar DK_1$ becomes further less attractive, the potential between $\bar D_1 K$ is the weakest, definitely too weak to form any bound state, which excludes the recently observed $X_1(2900)$ to be a $\bar D_1 K$ bound state. We also give the decay properties of the predicted $D K_1$ bound states.

description: We investigate the running gauge couplings of U(N) noncommutative gauge theories with compact extra dimensions. Power law running of the trace-U(1) gauge coupling in the ultraviolet is communicated to the infrared by ultraviolet/infrared mixing, whereas the SU(N) factors run exactly as in the commutative theory. This results in theories where the experimentally excluded trace-U(1) factors decouple with a power law running of the momentum in the extreme infrared, effectively hiding them from detection.

description: Phase stability and properties of two-dimensional phosphorus carbide, P$_x$C$_{1-x}$, are investigated using the first-principles method in combination with cluster expansion and Monte Carlo simulation. Monolayer P$_x$C$_{1-x}$ is found to be a phase separating system which indicates difficulty in fabricating monolayer P$_x$C$_{1-x}$ or crystalline P$_x$C$_{1-x}$ thin films. Nevertheless, a bottom-up design approach is used to determine the stable structures of P$_x$C$_{1-x}$ of various compositions which turn out to be superlattices consisting of alternating carbon and phosphorus nanoribbons along the armchair direction. Results of first-principles calculations indicate that once these structures are produced, they are mechanically and thermodynamically stable. All the ordered structures are predicted to be semiconductors, with band gap ranging from 0.2 to 1.2 eV. In addition, the monolayer P$_x$C$_{1-x}$ are predicted to have high carrier mobility, and high optical absorption in the ultraviolet region which shows a red-shift as the P:C ratio increases. These properties make 2D P$_x$C$_{1-x}$ promising materials for applications in electronics and optoelectronics.
A large HI cloud near the centre of the Virgo cluster

description: We report the discovery of a large HI cloud in the central regions of the Virgo cluster. It is 110 x 25 kpc in size and contains 3.4 x 10^8 Msol of HI. The morphology and kinematics of this cloud strongly suggest that it consists of HI removed from the galaxy NGC 4388 by ram-pressure stripping. It is more likely the result of an interaction of the ISM of NGC 4388 with the hot halo of the M86 group and not with the ICM centred on M87. The large extent of the plume suggests that gas stripped from cluster galaxies can remain neutral for at least 10^8 yr. Locally, the column density is well above 10^20 cm^-2, suggesting that the intra-cluster HII regions known to exist in Virgo may have formed from gas stripped from cluster galaxies. The existence of the HI plume suggests that stripping of infalling spirals contributes to the enrichment of the ICM. The HI object in the Virgo cluster recently reported by Minchin et al. may have a similar origin and may therefore not be a ``dark galaxy''.

description: A longitudinal mode-locked state can be converted to a transverse mode-locked state by exploiting the spectral and spatial filtering of an empty optical resonator. Carrier and amplitude modulation sidebands were simultaneously transmitted by the conversion resonator, yielding phase-locked superpositions of up to five transverse modes. Equivalently, an amplitude-modulated beam was converted into a beam that periodically moved across the transverse plane. Precise control over the spatial beam shape during oscillation was gained by independently altering the set of transverse modes and their respective powers, which demonstrated an increased level of control in the generation of transverse mode-locked states.

description: String theory provides numerous examples of duality between gravitational theories and unitary gauge theories. To resolve the black hole information paradox in this setting, it is necessary to better understand how unitarity is implemented on the gravity side. We argue that unitarity is restored by nonlocal effects whose initial magnitude is suppressed by the exponential of the Bekenstein-Hawking entropy. Time-slicings for which effective field theory is valid are obtained by demanding the mutual back-reaction of quanta be small. The resulting bounds imply that nonlocal effects do not lead to observable violations of causality or conflict with the equivalence principle for infalling observers, yet implement information retrieval for observers who stay outside the black hole.

description: Ancient Chinese is the essence of Chinese culture. There are several natural language processing tasks of ancient Chinese domain, such as ancient-modern Chinese translation, poem generation, and couplet generation. Previous studies usually use the supervised models which deeply rely on parallel data. However, it is difficult to obtain large-scale parallel data of ancient Chinese. In order to make full use of the more easily available monolingual ancient Chinese corpora, we release AnchiBERT, a pre-trained language model based on the architecture of BERT, which is trained on large-scale ancient Chinese corpora. We evaluate AnchiBERT on both language understanding and generation tasks, including poem classification, ancient-modern Chinese translation, poem generation, and couplet generation. The experimental results show that AnchiBERT outperforms BERT as well as the non-pretrained models and achieves state-of-the-art results in all cases.

Here, we localize Plasmodium falciparum patatin-like phospholipase 2 (PfPNPLA2, PF3D7_1358000) to the mitochondrion and reveal that disruption of the PfPNPLA2 gene impairs asexual replication. PfPNPLA2-null parasites are hypersensitive to proguanil and inhibitors of the mitochondrial ETC, including atovaquone. In addition, PfPNPLA2-deficient parasites show reduced mitochondrial respiration and reduced mitochondrial membrane potential, indicating that disruption of PfPNPLA2 leads to a defect in the parasite ETC. Lipidomic analysis of the mitochondrial phospholipid cardiolipin (CL) reveals that loss of PfPNPLA2 is associated with a moderate shift toward shorter-chained and more saturated CL species, implying a contribution of PfPNPLA2 to CL remodeling. PfPNPLA2-deficient parasites display profound defects in gametocytogenesis, underlining the importance of a functional mitochondrial ETC during both the asexual and sexual development of the parasite. IMPORTANCE For their proliferation within red blood cells, malaria parasites depend on a functional electron transport chain (ETC) within their mitochondrion, which is the target of several antimalarial drugs. Here, we have used gene disruption to identify a patatin-like phospholipase, PfPNPLA2, as important for parasite replication and mitochondrial function in Plasmodium falciparum. Parasites lacking PfPNPLA2 show defects in their ETC and become hypersensitive to mitochondrion-targeting drugs. Furthermore, PfPNPLA2-deficient parasites show differences in the composition of their cardiolipins, a unique class of phospholipids with key roles in mitochondrial functions. Finally, we demonstrate that parasites devoid of PfPNPLA2 have a defect in gametocyte maturation, underlining the importance of a functional ETC for parasite transmission to the mosquito vector.

description: The prediction of aircraft aerodynamic quantities of interest remains among the most pressing challenges for computational fluid dynamics. The aircraft aerodynamics are inherently turbulent with mean-flow three-dimensionality, often accompanied by laminar-to-turbulent transition, flow separation, secondary flow motions at corners, and shock wave formation, to name a few. However, the most widespread wall models are built upon the assumption of statistically-in-equilibrium wall-bounded turbulence and do not faithfully account for the wide variety of flow conditions described above. This raises the question of how to devise models capable of accounting for such a vast and rich collection of flow physics in a feasible manner. In this work, we propose tackling the wall-modeling challenge by devising the flow as a collection of building blocks, whose information enables the prediction of the stress as the wall. The model relies on the assumption that simple canonical flows contain the essential flow physics to devise accurate models. Three types of building block units were used to train the model: turbulent channel flows, turbulent ducts and turbulent boundary layers with separation. This limited training set will be extended in future versions of the model. The approach is implemented using two interconnected artificial neural networks: a classifier, which identifies the contribution of each building block in the flow; and a predictor, which estimates the wall stress via non-linear combinations of building-block units. The output of the model is accompanied by the confidence in the prediction. The latter value aids the detection of areas where the model underperforms, such as flow regions that are not representative of the building blocks used to train the model. The model is validated in a unseen case representative of external aerodynamic applications: the NASA Juncture Flow Experiment.

description: In the beginning of the 1950's, Wigner introduced a fundamental deformation from the canonical quantum mechanical harmonic oscillator, which is nowadays sometimes called a Wigner quantum oscillator or a parabose oscillator. Also, in quantum mechanics the so-called Wigner distribution is considered to be the closest quantum analogue of the classical probability distribution over the phase space. In this article, we consider which definition for such distribution function could be used in the case of non-canonical quantum mechanics. We then explicitly compute two different expressions for this distribution function for the case of the parabose oscillator. Both expressions turn out to be multiple sums involving (generalized) Laguerre polynomials. Plots then show that the Wigner distribution function for the ground state of the parabose oscillator is similar in behaviour to the Wigner distribution function of the first excited state of the canonical quantum oscillator.

Legend of science. External constructions by the extended ›family‹ – the biography of Paul Ehrlich
Creators: name: Hüntelmann, Axel C.
Publisher: name: InterDisciplines. Journal of History and Sociology
Year: 2010

description: Axel Hüntelmann sketches the early attempts of Paul Ehr­lich’s family, who started to commission a biography after his death. By these early efforts to produce a biography of »Ehrlich the Nobelprize winner«, Huentelmann illustrates the inherent modes which then created legends. Similar to other scientists – like Robert Koch and Louis Pasteur – the early biographies on Ehrlich portrayed a genius searching for the scientific truth in his laboratory rather than a realistic picture of his life and career. In his article Huentelmann demonstrates the process of myth-construction by means of the alleged chemical talent of Ehrlich. His early chemical experiments during his years of studying were gradu­ally moved to his school days and associated with the scientific interest of his grandfather. Thus, through this genealogical link, Ehrlich’s career and his success appeared as the inevitable endpoint of a natural predis­position.

Isolation, imposture and the impact of the ›Taboo‹ in Stalinist society.  A diarist on the verge of loneliness
Creators: name: Griesse, Malte
Publisher: name: InterDisciplines. Journal of History and Sociology

description: The article reconsiders the significance of atomization in Stalinist society and reassesses the phenomenon of imposture as a constituent part of the system’s functioning. In historiography, impostors have been regarded as subverters who perfectly mastered Bolshevik language and behavioral codes to take advantage of the revolutionary chaos and the system’s dysfunctions: thus they revealed the regime’s incapacity to establish totalitarian control. This view overlooks that parallel to its campaigns for transparency and unambiguity the Stalinist regime systematically pushed large segments of the population into double-dealing, i.e. into hiding central aspects of their (past) lives. The impact of such dissimulation is explored on the basis of an unedited personal diary written by a former Menshevik converted to Bolshevism who silenced his former political allegiance and committed to paper his sufferings from loneliness and political guilt. His diary served him to “leave a trace” and to “find consolation” in “conversations with himself”. It is a liminal document that perfectly illustrates Arendt’s distinction between solitude as a domain of dialogical thinking and loneliness as a state of readiness to succumb to purely deductive logical (or totalitarian) thinking, a distinction that is developed with the aid of the multiple-personality-model as proposed in ego-states-psychology.

Fundamental Groups of Galois Closures of Generic Projections

description: For the Galois closure $\Xgal$ of a generic projection from a surface $X$, it is believed that $π_1(\Xgal)$ gives rise to new invariants of $X$. However, in all examples this group is surprisingly simple. In this article, we offer an explanation for this phenomenon: We compute a quotient of $π_1(\Xgal)$ that depends on $π_1(X)$ and data from the generic projection only. In all known examples except one, this quotient is in fact isomorphic to $π_1(\Xgal)$. As a byproduct, we simplify part of the computations of Moishezon, Teicher and others.

The writing self. Rousseau and the author’s identity
Creators: name: Jung, Theo
Publisher: name: InterDisciplines. Journal of History and Sociology

description: In 1749, while on the road to Vincennes to visit his friend Diderot in prison, Rousseau had an inspirational experience that prove to be a deciding moment in his life story. In his many autobiographical writings, he would time and again interpret this event as the seminal point of his identity as a writer. Taking the conflicting contemporary interpretations of the Vincennes episode as a starting point, this article asks in what way modern, post-subjectivist theories of the self can enrich our understanding of historical events, while at the same time providing answers to wider questions concerning the ways in which historically changing and contextually specific forms of what it means to be a self are constructed, intepreted, articulated and ›put into practice‹. To this end, Rousseau’s ›illumination‹ and its subsequent interpretations are interpreted in the light of contemporary controversies over the identity of the writer that developed against the background of fundamental changes in the social and economic structure of the literary field.

description: Possibility of beam combining and clean-up using Orientational Stimulated Scattering in a Nematic Liquid Crystal is considered. We numerically study the dynamics of the process and find that back-conversion process tends to limit the effective interaction strength. Instability of the steady state of cross-phase modulation is demonstrated, when both waves have the same frequency. We show that high conversion efficiency can be achieved, and that the shape and wave-front of the amplified output signal are robust with respect to amplitude and phase distortions of the input pump.

description: The purpose of this paper is to present some elements of one or more paradigms for assessing a region's economic growth prospects and related infrastructure requirements. These concerns are central to a regional policy that offers guidance for individual decision makers of local governments and their resident populations. A paradigm for regional policy is a model of regional structure and activity that provides a basis for understanding and foresight about regional growth and change. It is a framework for well-targeted infrastructure investments, vigorous and sustained capacity-building, and continuing efforts in intra-regional cooperation. Critical infrastructure for globally-competitive business enterprise includes air transportation and the accompanying distribution system that brings together all transportation modes to provide access to regional and global markets. Capacity-building refers to the successful application and integration of the means of control and foresight - good management coupled with realistic anticipation about the future - in both private and public management. Intra-regional cooperation starts with the public agencies engaged in infrastructure planning. We focus on implications of a new paradigm for regional policy on investment in growth-influencing resources and facilities, and their location. We relate these decision variables to the recurring themes that apply to any region with high hopes of sustainability.
