This paper focuses on the Dirichlet and the Dirichlet-multinomial distributions to analyze one definition of the cycle based on three economic performance regimens: augmentation, stagnation and diminution. We use data from 142 economies grouped in seven clusters during the second half of the last century, a period which has witnessed various structural changes. Furthermore, this paper advances to investigate what the probabilities are of reaching significant  positive  growth  rates  ⎯the  frequency  of  the  augmentation  regimen⎯  which  prevailed  during     the decade from 1950 to 1960, using Bayesian statistics.

The article summarizes the approaches to the definition of specialization in agriculture. The factors and conditions for the optimal location of agricultural production in the region are shown. Unlike the pre-reform period, when the main link in the specialization of agricultural production were collective and state farms, to a lesser extent - subsidiary farms of industrial enterprises, today territorial specialization at the level of municipal production volumes and create the necessary infrastructure for this. Specialization should be viewed as a process of structural changes in production, when resources are redistributed between the production of various types of products, new proportions are formed, in agriculture - primarily in land use. In this case, it is proposed to determine the specialization of municipal districts based on their contribution to the production of specific types of products in the region and average annual growth rates. Based on the ratio of these indicators, the following types of municipalities were identified in the areas of specialization - growth points (with a high share in the volume of production and high growth rates) and stagnating territories (when a high share in the volume is combined with low growth rates). Compiled maps of the specialization of agricultural production in the municipal districts of the Republic of Bashkortostan for today and for the future, for the period up to 2030. Determination of the specialization of agricultural production in municipal districts for the future, allows you to create the necessary infrastructure in them, taking into account the changed conditions, to make fuller use of the existing potential.

ABSTRACT Frustrated magnetic phases have been a perennial interest to theoreticians wishing to understand the energetics and behavior of quasi-chaotic systems at the quantum level. This behavior also has potentially wide applications to developing quantum data-storage devices. Several minerals are examples of such phases. Since the definition of herbertsmithite, Cu3ZnCl2(OH)6, as a new mineral in 2004 and the rapid realization of the significance of its structure as a frustrated antiferromagnetic phase with a triangular magnetic lattice, there has been intense study of its magnetic properties and those of synthetic compositional variants. In the past five years it has been recognized that the layered copper hydroxyhalides barlowite, Cu4BrF(OH)6, and claringbullite, Cu4FCl(OH)6, are also the parent structures of a family of kagome phases, as they also have triangular magnetic lattices. This paper concerns the structural behavior of claringbullite that is a precursor to the novel frustrated antiferromagnetic states that occur below 30 K in these minerals. The reversible hexagonal (P63/mmc) ↔ orthorhombic (Pnma or Cmcm) structural phase transition in barlowite at 200−270 K has been known for several years, but the details of the structural changes that occur through the transition have been largely unexplored, with the focus instead being on quantifying the low-temperature magnetic behavior of the orthorhombic phase. This paper reports the details of the structural phase transition in natural claringbullite at 100−293 K as studied by single-crystal X-ray diffraction. The transition temperature has been determined to lie between 270 and 293 K. The progressive disordering of Cu at the unusual trigonal prismatic Cu(OH)6 site on heating is quantified through the phase transition for the first time, and a methodology for refining this disorder is presented. Key changes in the behavior of Cu(OH)4Cl2 octahedra in claringbullite have been identified that suggest why the Pnma structure is likely stabilized over an alternative Cmcm structure. It is proposed that the presence of a non-centrosymmetric octahedron in the Pnma structure allows more effective structural relaxation during the phase transition than can be achieved by the Cmcm structure, which has only centrosymmetric octahedra.

OBJECTIVEUsing an imaging-based prospective comparative study of 709 eligible patients that was designed to assess lumbar spinal stenosis (LSS) in the ages between 16 and 82 years, the authors aimed to determine whether they could formulate radiological structural differences between the developmental and degenerative types of LSS.METHODSMRI structural changes were prospectively reviewed from 2 age cohorts of patients: those who presented clinically before the age of 60 years and those who presented at 60 years or older. Categorical degeneration variables at L1–S1 segments were compared. A multivariate comparative analysis of global radiographic degenerative variables and spinal dimensions was conducted in both cohorts. The age at presentation was correlated as a covariable.RESULTSA multivariate analysis demonstrated no significant between-groups differences in spinal canal dimensions and stenosis grades in any segments after age was adjusted for. There were no significant variances between the 2 cohorts in global degenerative variables, except at the L4–5 and L5–S1 segments, but with only small effect sizes. Age-related degeneration was found in the upper lumbar segments (L1–4) more than the lower lumbar segments (L4–S1). These findings challenge the notion that stenosis at L4–5 and L5–S1 is mainly associated with degenerative LSS.CONCLUSIONSIntegration of all the morphometric and qualitative characteristics of the 2 LSS cohorts provides evidence for a developmental background for LSS. Based on these findings the authors propose the concept of LSS as a developmental syndrome with superimposed degenerative changes. Further studies can be conducted to clarify the clinical definition of LSS and appropriate management approaches.

In modern conditions of development of integration processes in the world economy, special importance is attached to the transport sector. The formation of a single transport space (STS) in the regions creates additional opportunities for the economic development of the integrating countries. At the same time, the literature does not pay enough attention to the definition of the essence of the single transport space and the classification of integration associations according to the degree of its development. Therefore, there is a need to develop such a classification. The article substantiates the expediency of classification of integration associations according to the degree of development of a single transport space. The author's formal-logical classification is developed, which is based on three basic types of a single transport space: transport and logistics type provide a positive multiplier of integrated economic growth for all participating countries; innovative-logistic and customs-logistic types cause polarization in the action of the multiplier of integrated economic growth (in particular, both positive and negative growth rates of GDP values of the participating countries are possible); industrial and logistics type provide a zero multiplier of integrated economic growth for all participating countries. The conclusion is made about the possibility of unification and harmonization of transport space in the practice of integration associations on the basis of the developed classification.

The process of financial liberalization draws attention as a process that took place after the 1980s and led by the strong countries, in order to overcome the narrowing in the economies of the world countries which have become polarized because of the Second World War and the Cold War period immediately following the Second World War. In this chapter, firstly, the definition of the financial liberalization period and the effects according to the countries are examined, while the risk and crisis issues are also evaluated. Economic and political crises that have occurred in Turkey after the financial liberalization process in ongoing part of the study also were assessed by considering the effects on the economy. In this context, the economic and political crisis in Turkey are analyzed as to their effects on the country's economic performance. Accordingly, every 10 years, an economic and political crisis in Turkey took place. The country's economy is affected negatively in the macro-frame.

The agenda for marketing research in the 1980s, to a great extent, has already been set by the events of the 1970s. Agriculture is in a period of transition in which commodity surpluses are expected to be less of a problem area. International markets are expanding, and the delivery systems have become complex in both structure and in the functions performed. The dynamics of the marketplace obviously influence the research agenda.Before looking at the changing research needs for agricultural marketing, a definition of the concept is needed. For the context of this paper, marketing research is defined to be the process of assimilation and creation of information on the economic performance of potential and existing arrangements that facilitate the assembling, distribution, and consumption of foods, fibers, and ornamentals.

The Eu

Activity picked up markedly in the EU area last year; growth was estimated to have been 2.6 per cent compared with 1.8 per cent recorded in 1996. However the aggregate movement masks some significant divergences in economic performance. Growth was relatively modest, at between 2–2½ per cent in Germany, France and Austria, whilst Italy and Sweden recorded growth rates below 2 per cent for the second year running. The fastest growth was achieved in the Irish Republic where output expanded by over 10 per cent last year, following cumulative growth of 27 per cent in the previous three years. Finland also recorded rapid growth of nearly 6 per cent and nearly all the remaining EU countries enjoyed growth rates of 3 per cent or above. Outside the EU, activity remained robust in Norway, Poland and Hungary but was markedly weaker in the Czech Republic and Switzerland. Indeed real GDP has barely changed in Switzerland since 1990, partly reflecting the strength of the Swiss franc, although there are now signs that growth will be stronger in 1998 as the franc has depreciated since the end of 1995.
