Two sprout-damaged wheat lots with the falling number values of 91 and 65 were heat-treated by immersing the grain in water of temperatures of 80, 85, 90 and 100°C, followed by rapid chilling in water. The purpose of the treatment was to suppress the excess a-amylase activity in the outer layers of the kernels. The a-amylase activity following the treatment was measured by the falling number test. The increase in the falling number value was the greater the longer the treatment lasted and the higher the water temperature was. Processing lasting 30 sec at 80, 85, 90 and 100°C increased the falling number value of the one lot from 91 to 105, 117, 133 and 238 and of the other lot from 65 to 69, 70, 98, 163, respectively. As the falling numbers increased the wet gluten content of the samples decreased. These changes had a negative correlation. The gluten quality showed heat damage when the amount of gluten had dropped by about 5 and 2 precentage units in the lots with the falling numbers 91 and 65, respectively. This occurred at processing of the lot of better quality for 70, 20, 13 and 6 sec in the order of increasing temperature. The corresponding durations for the other lot were above 60, 30, 20 and 6 sec. During these treatments the falling number values rose from 91 to 104—129 and from 65 to 70—71. These results were confirmed by farinogram and extensigram determinations and by baking tests. The same processing conditions affected more severely the lot having the better initial quality than the lot with greater sprout damages.

Sprout-damaged rye with the falling number of 87 was heat-treated by immersing the grain in water having temperatures of 80, 90 and 100°C. The treatment lasted at the most 60 sec and was followed by an immediate chilling process. The aim of the treatment was to suppress the excess of a-amylase activity in the outer layers of the kernels. The changes in the quality of the rye were determined by the falling number test, amylograph test and baking tests in which yeast and no acid was added. All the performed treatments affected the results of the quality determinations. Treatment at 80, 90 and 100°C lasting 30 sec raised the falling number values to 102, 117 and 155, respectively. After treatment for 60 sec the values were 101, 142 and 223. In the amylograms the peak viscosity increased markedly. Processing at 100 and 90°C for more than 20 sec resulted in an increase of the peak viscosity beyond 1000 B.U. The peak temperature of all the samples was rather low and some decrease in the peak temperature was indicated at the processing temperatures of 80 and 90° C. The loaf volumes of loaf made from the treated samples were all lower than the volume of the loaf from the untreated sample. The samples treated for 30 and 60 sec at 100°C gave lowest volumes. Stickiness of the doughs was diminished by the more severe processing conditions, as also were dampness and elasticity of the crumb. All loaves except the ones made of grain heated at 100“C for 30 and 60 sec had a rather large cavity beneath the crust. The samples processed at 90 and 100°C for 30 and 60 sec gave a lighter brown crust colour than the rest of the samples.

Starting from previous studies in professional caregivers of people with dementia and other diseases in institutionalized centers of different regions, the aim of this study was to compare burnout levels that workers present depending on the center, to create a caregiver profile with high professional accomplishment and to describe the quality of life that residents perceive Murcia and Barcelona. The instruments used were the Maslach Burnout Inventory (MBI), the Professional Caregiver Survey developed ad hoc and the Brief Questionnaire of Quality of Life (CUBRECAVI in Spanish) on residents. The results show, on the one hand, that levels of professional accomplishment may be paradoxically higher in the case of catastrophe and, on the other hand, the 98.2% of users are satisfied with the residence in which is located and 81.8% with the manner in which occupy the time. The conclusions that are extrapolated from the study shed light on the current situation of workers and residents and the influence that an earthquake can have on them.

Integrating the art appreciation course into the talent cultivation plan of tobacco profession has become the major way for colleges and universities to implement aesthetic education. This is also one of the reform measures of public curriculum in colleges and universities in the new era. By clarifying the concept connotation and policy requirements of the art appreciation course, and combining the talent training characteristics of tobacco profession, the construction of tobacco profession can be promoted. By doing this, on the one hand, it is conducive to consolidating the talent training plan of tobacco profession. On the other hand, it can cultivate the artistic ability of students majoring in tobacco, expand their artistic knowledge, and effectively build up their aesthetic quality and artistic level. As the consequence, the talent training quality of tobacco profession can be improved.

This chapter relies on a case study featuring the business network around Stella, an Italian home textile manufacturer, to illustrate the challenging issue of engaging other firms into complex “Network Process Re-engineering” (NPR) projects. While the strict technological dimension of selecting, developing, and implementing ICT solutions is certainly very important and poses several challenges to this type of projects, this chapter focuses on other types of challenges, namely those pertaining to the nature and quality of relationships between the actors taking part in a NPR project. We stress the importance of the connection between the specific inter-organizational activities that need to be redesigned and coordinated in better ways, on the one hand, and the bonds existing among the actors, on the other hand. We suggest that very advanced and complex coordination tasks, entailing sensitive communication patterns, can be tackled only if supported by strong, integrative relationships characterized by high trust and commitment between the involved parties. We conclude by discussing how the pivotal firms or the “strategic centers” of a network can support and facilitate complex change projects like NPR by carefully combining different strategies, whereby they both exert coercive power and make concessions to their counterparts in the network.

The European Higher Education Area, created to contribute to the development of quality education and encourage cooperation between Member States of the European Union, has created an opportunity for reflection on teaching methods in universities. These circumstances provide momentum for the use of learning strategies. Along these lines, this chapter presents work done on concept mapping, one of the methods that could significantly help prepare both students and teachers for the new roles expected of them. The results of two lines of study are presented: on the one hand, research that analyses the influence of the differential use of concept maps on the quality of learning; and on the other, an innovation in the use of concept maps in a course developed in the area of initial teacher training. Both initiatives serve to highlight increased interest in concept mapping in the field of learning and especially in collaborative learning.

What insights and advantages do rhetorical approaches offer over other methods of exploring social and political discourse? This article aims to clarify the contribution of rhetorical analysis by exploring its distinctive, hermeneutic attention to public speech. Public speaking is, accordingly, viewed as a practice of assembling meaningful interpretations in specific situations. Central here is a temporal dimension. Analysing rhetoric involves grasping discourse, on the one hand, as concretely situated in response to proximate constraints and, on the other hand, as a medium to move beyond the situation towards a future. Following John Caputo’s reading of Derrida, I argue that, examined rhetorically, public speech enacts a ‘negotiation’ of past and future, intertwining conditional – and hence partially calculable – positions with an ‘unconditional promise’ to prepare for what comes. Although compatible with other approaches, rhetorical analysis is uniquely attuned to this intrinsically ethical and political quality of discursive action.

This study compares the development and use of evaluative expressions in the English narratives elicited from 80 Chinese–English bilinguals and 80 American monolingual peers at four ages – five, eight, ten, and young adults – using the wordless picture book Frog, where are you? (Mayer, 1969). Results revealed both similarities and differences between monolingual and bilingual groups. On the one hand, regardless of bilingual status, there is a clear age-related growth in the development and use of evaluative expressions. On the other hand, bilingual children in our study differed from monolingual children in the quantity and quality of evaluative clauses used. The results are discussed with respect to linguistic and cultural differences between English and Chinese.

Nearly 30 years of transformation of the sociopolitical and legal, socioeconomical and financial, sociocultural and welfare, and socioenvironmental dimensions in both Central and Eastern Europe, including Ukraine, has led to a change of the social quality of daily circumstances. On the one hand, the interconnection and reciprocity of these four relevant dimensions of societal life is the underlying cause of such changes, and on the other, the state as main actor of the sociopolitical and legal dimension is the initiator of those changes. Applying the social quality approach, I will reflect in this article on the consequences of these changes, especially in Ukraine. In comparison, the dominant Western interpretation of the “welfare state” will also be discussed.

This paper argues that inflation targeting is a strategy that can be under certain conditions adopted by central banks in countries in transition even though their typical goal is to disinflate instead of stabilising low inflation. On the one hand, according to the Czech experience, inflation targeting offers several benefits, such as increasing control over expectations and short-term flexibility of monetary strategy, that are attractive for economy in transition. On the other hand, constraints imposed by period of transition as well as by openness of economy are present no matter which monetary strategy is chosen by the central bank. Implied costs should not be attributed to a particular monetary strategy. Inflation targeting has made various factors constraining monetary policy more visible and, as a result, requirements on the quality of decisions as well as on communication strategy have increased.
