Marketing Problems

The ability relating to problem identification and problem solving play an important role in the thinking process of managers. An important part of this process is problem formulation, which involves problem categorization. How the problem is classified and defined is crucial to the solution of the problem as it guides further action by the manager. This study reports a ranking of problems perceived as important by different levels of managers in an organization, which are then categorized along the strategic-operational and internal-external dimensions. The hypothesis that strategic problems are perceived to be more important than operational problems by higher-level managers is empirically tested. The results partially supported the hypothesis and suggested an internal and operational focus in the organization. There seems to be a lack of marketing orientation. The paper also creates insight into how problems are defined and labeled by managers and staff of an organization. The focus of this study is on marketing problems of a Fertilizer Co-operative of India operating at all India level and involved in complete value chain of fertilizer product category but which has been facing declining sales in the past two years.

Some problems exist in the way in which children with language disorders are classified, diagnosed, and treated. To help resolve these problems, clinicians need to function as clinical scientists in the diagnostic and therapeutic process. The classification, diagnosis, and treatment of children with language disorders should reflect hypotheses about the different levels of cause-effect relationships that exist among the structures, processes, and behaviors involved in language. Specifically, hypotheses about the primary and secondary deficits that characterize language disorders need to be made. That is, symptoms that reflect the underlying deficit must be differentiated from symptoms that reflect secondary and compensatory deficits. Clinical examples are presented to illustrate the way in which classification, diagnosis, and treatment of language-disordered children would proceed using these notions.

The contemporary condition of soil cover in Ukraine is characterized. The attention is focused onto widespread degradation processes in soils. The causes that determine the development of these negative processes are considered. The contemporary informational support for the condition of soil cover in Ukraine is estimated. In general, the current available information is of narrow-departmental nature, obtained by different methods and non-correlated monitoring programs. As a rule, it is stored in under-structured databases, incompatible with other information systems; mainly recorded on paper media unusable with modern technologies, whereby such information resources are diffi cult to be compiled together. These disadvantages are strong constraints against consistent usage of materials for evaluation, forecast and management of changes in the soil cover. The Soil Observation program should thereby be combined with Agrochemical Passportization and ecology-ameliora- tive monitoring; in other words, the application of innovative soil-agrochemical methodology is considered. Each individual type of surveys shall complement the others, and taken altogether, they shall constitute a con- sistent Information System, capable of solving the problems of assessing the condition, forecasting, manage- ment, usage and protection of soil resources. The monitoring procedures should be conducted on the basis of a new soil concept in line with unifi ed programs and methods, so as to meet European approaches to the maxi- mum extent. Such a technical composition enables getting information on present-day processes in soils, and is the only combination that actually helps us to “ecologize” our knowledge of soils, which is the leading trend in the scope of global soil-science. Thus obtained results will serve as a State-owned tool which would subse- quently facilitate the use and protection of soil resources all over the country, to be involved in a united global soil-information scope. The attention is focused onto social signifi cance of the information on soils and their fertility in terms of land resources optimization, as well as the formation of sustainable land use in Ukraine. Aim. To demonstrate the long-term effect of different ways of tillage of typical low-humus chernozem on the change in humus content and composition and the direction of transformation processes of organic fertili- zers. To study the changes in the structure of energy reserves in group and fractional composition of humus in typical low-humus light-loamy chernozem of the Forest-Steppe of Ukraine. Methods. Field, laboratory, microbiological, computational, mathematical and statistical. Results. It was determined that in conditions of long-term subsurface tillage the most effi cient humus accumulation occurs in the 0–20 cm layer of chernozem with simultaneous increase in its content in the lower part of the processed layer without any accumulation differentiation. Surface tillage leads to expressed differentiation in humus accumulation in the 0–20 cm layer of soil (0.005 % per year). When 6 t/ha of humus are replaced by 7 t/ha of by-products the intensity of humus accumulation is decreasing regardless of the way of tillage, but humus accumulation was found to be the most effi cient for subsurface tillage. The application of subsurface tillage leads to the increase in the ratio of C HA : C FA , which is conditioned by the increase in the humifi cation of plant remains of by-products in the 0−20 cm layer of soil by 110–112 % – for subsurface tillage, and by 105 % – for surface tillage. Conclusions. It was established that systematic subsurface tillage of typical chernozem of the Left-Bank Forest-Steppe of Ukraine leads to the structuring both of the total reserves of energy С org , and its quality content, aimed at the increase in the intensity of the processes of humifi cation and accumulation of organic carbon, and the decrease in miner- alization. The ratio of energy reserves С org of humic acids to fulvic acids in the 0−30 cm layer of chernozem is 1.85−1.87 regardless of the way of tillage, which testifi es to the repeatability of humus accumulation, but the total reserves of energy С org was higher for subsurface tillage (+ 31 Teracalorie/ha) compared to deep plough- ing. As for the surface tillage, the energy enrichment was at the level of deep ploughing.

High performance sport has a major impact on the physiological adaptations of the respiratory system. The importance of the optimal functioning of this system is essential to achieve top results in high performance sport but also in maintaining a long term health status. Science journals present numerous studies that highlight the benefits of practicing Tai Chi on the general population, with effects ranging from improving cardiac function, to influencing the immune system. The purpose of this study is to identify whether by practicing Tai Chi forms a athlete can change their breathing pattern and develop their respiratory amplitude. The subjects of the study were 22 fencing practitioners, accredited at the Iași Municipal Sports Club (C.S.M. Iași), aged between 14 and 18 years, with over 3 years of competitive activity. Materials and method: The study participants were evaluated initially and at the end of 7 months of practice. The frequency was 3 sessions per week, and the duration of each session was 20-30 minutes. The evaluation consisted in measuring the circumference of the thorax at 3 different levels: subaxillary, medial thorax (T6-T7) and lower rib (diaphragmatic) in maximal inspiration and expiration. Conclusions: A constant evolution is observed in most of the exposed cases. In cases where this evolution is not visible, a change in the breathing mode can be noticed, transforming from an upper rib breathing into a thoracic or abdominal breathing. With the exception of one case, all subjects had an improvement of the value in the lower rib level.

Henry VIII fought many wars, against the French and Scots, against rebels in England and the Gaelic lords of Ireland, even against his traditional allies in the Low Countries. But how much did they really affect his subjects? And what role did Henry’s reign play in the long-term transformation of England’s military capabilities? This book searches for the answers to these questions in parish and borough account books, wills and memoirs, buildings and paintings, letters from Henry’s captains, and the notes readers wrote in their printed history books. It looks back from Henry’s reign to that of his grandfather, Edward IV, who in 1475 invaded France in the afterglow of the Hundred Years War, and forwards to that of Henry’s daughter Elizabeth, who was trying by the 1570s to shape a trained militia and a powerful navy to defend England in a Europe increasingly polarized by religion. War, it shows, marked Henry’s England at every turn: in the news and prophecies people discussed, in the money towns and villages spent on armour, guns, fortifications, and warning beacons, in the way noblemen used their power. War disturbed economic life, made men buy weapons and learn how to use them, and shaped people’s attitudes to the king and to national history. War mobilized a high proportion of the English population and conditioned their relationships with the French and Scots, the Welsh and the Irish. War should be recognized as one of the defining features of life in the England of Henry VIII.

Many companies are forming data analytics teams to put data to work. To enhance procurement practices, chief procurement officers (CPOs) must work effectively with data analytics teams, from hiring and training to managing and utilizing team members. This chapter presents the findings of a study on how CPOs use data analytics teams to support the procurement process. Surveys and interviews indicate companies are exhibiting different levels of maturity in using data analytics, but both the goal of CPOs (i.e., improving performance to support the business strategy) and the way to interact with data analytics teams for achieving that goal are common across companies. However, as data become more reliably available and technologies become more intelligently embedded, the best practices of organizing and managing data analytics teams for procurement will need to be constantly updated.

This research was instigated by the fact that during the last decade annually repeated shallow disk tillage on the same field became frequent practice in Hungary. In order to study the changes of soil condition associated with disk tillage and to assess it is consequences, long-term tillage field experiments with different levels of nutrients were set up in 1991 (A) and in 1994 (B) on Chromic Luvisol at Gödöllö. The effects of disk tillage (D) and disk tillage combined with loosening (LD) on soil condition, on yield of maize and winter wheat, and on weed infestation were examined. The evaluation of soil condition measured by cone index and bulk density indicated that use of disking annually resulted in a dense soil layer below the disking depth (diskpan-compaction). It was found, that soil condition deteriorated by diskpan-compaction decreased the yield of maize significantly by 20 and 42% (w/w), and that of wheat by 13 and 15% (w/w) when compared to soils with no diskpan-compaction. Averaged over seven years, and three fertilizer levels, the cover % of the total, grass and perennial weeds on loosened soils were 73, 69 and 65% of soils contained diskpan-compaction.

Socioeconomic Issues

We explore the factors behind the long-term erosion of National Social Dialogue Institutions (NSDIs) to provide insights about the conditions for their revitalization. By applying policy analysis insights into the industrial relations field, we argue that limited policy effectiveness goes a long way towards explaining the erosion experienced by many NSDIs worldwide in recent years. Drawing on a global survey and on case studies of NSDIs in Brazil, Italy and South Korea, we show that these institutions’ policy effectiveness crucially depends on combinations of their problem-solving capacity, an encompassing mandate to deal with relevant socioeconomic issues and an enabling environment that grants the inclusion of social dialogue into decision making. With regard to rekindling their role, the article provides substantial evidence that two sub-dimensions of effectiveness are key: enjoying political support and having an ‘effective mandate’ as opposed to relying on just a formal remit to deal with socioeconomic issues of interest.
