    University of Minnesota Master of Science thesis. March 2015. Major: Food Science. Advisor: Dr. Zata Vickers. 1 computer file (PDF); vi, 34 pages.Increasing interest in whey protein beverages stems from the wide range of nutritional benefits whey proteins have to offer. A useful characteristic of whey proteins is their solubility over a wide pH range, however in order to ensure clarity of a ready-to-drink whey protein beverage, it needs to be manufactured at a pH of approximately 3.4. At an acidic pH of 3.4, the beverages become astringent and can lead to consumer acceptability issues. The main objective of this research was to determine which, if any, of four different acids (hydrochloric, malic, phosphoric, tartaric) achieved the lowest perceived astringency rating when used to acidify a 4% (w/v) whey protein isolate (WPI) solution to pH 3.4. A secondary objective was to identify the buffer capacities of each acid in both a water solution and WPI solution, in efforts to detect a relationship between buffer capacity and perceived astringency. Sourness ratings for each sample were also gathered. A 4% (w/v) WPI solution acidified with hydrochloric acid generated the lowest perceived astringency and sourness ratings. Conversely, the malic acid WPI sample produced the highest perceived astringency rating. Additionally, hydrochloric and phosphoric acid samples buffered the least within the pH range of interest (3.4-7.0). This research indicates a potential relationship between the perceived astringency of an acidified-WPI solution and the buffer capacity of the acidulant used

    International capital mobility in an era of globalisation: adding a political dimension to the 'Feldstein–Horioka Puzzle'

    Get PDF
    The debate about the scope of feasible policy-making in an era of globalisation continues to be set within the context of an assumption that national capital markets are now perfectly integrated at the international level. However, the empirical evidence on international capital mobility contradicts such an assumption. As a consequence, a significant puzzle remains. Why is it, in a world in which the observed pattern of capital flows is indicative of a far from globalised reality, that public policy continues to be constructed in line with more extreme variants of the globalisation hypothesis? I attempt to solve this puzzle by arguing that ideas about global capital market integration have an independent causal impact on political outcomes which extends beyond that which can be attributed to the extent of their actual integration

    And the first shall be the last

    This study analyzes the puzzle of Hungarian economic drifting in a long run perspective. The underlying puzzle for the investigation is why bad policies are invariably popular and good policies unpopular, thus why political and economic rationality never overlap. The first part of the article summarizes in eight points the basic features of the postwar period. Then six lessons are offered, which might be useful for other countries in transition or for students of comparative economics and politics, lessons that can be generalized on the basis of the individual country experience

    Organizational Evaluation and Authority

    Get PDF
    The authors describe four kinds of authority rights (legitimate attempts to control others) and analyze organizational authority systems in terms of the process by which participants’ performances are evaluated. They present theoretical ideas including a prediction that certain incompatible authority systems can block participants' ability to attain satisfactory evaluations. That problem, in turn, causes instability of the organizational system

    PRIVATE SAVINGS IN TRANSITION ECONOMIES: ARE THERE TERMS OF TRADE SHOCKS?

    Get PDF
    The paper examines the impact of terms of trade shocks on private savings in the transition economies after accounting for the effect of other determinants. Economic agents in the transition economies are subject to tight credit constraints which are more pronounced during bad state of nature. Thus, adverse shocks to commodity prices in the world market can force them to reduce savings by a larger amount than they would otherwise have. Empirical analysis using a dynamic panel model and data from twenty one transition economies confirm that most of the determinants of savings identified in the literature also apply to the transition economies. Favorable movements in both the permanent and transitory components of the terms of trade have a significant positive impact on private savings with transitory movements having a larger impact than the permanent component. This reflects the lack of access to foreign borrowing that many of the transition economies have faced during the last decade. Although the impact of terms of trade shocks are found to be asymmetric, the magnitude of the impact appears to be small. The results are robust for alternative estimators, determinants, and country groupings.http://deepblue.lib.umich.edu/bitstream/2027.42/39958/3/wp572.pd

    Economic liberalization and the antecedents of top management teams: evidence from Turkish 'big' business

    Get PDF
    There has been an increased interest in the last two decades in top management teams (TMTs) of business firms. Much of the research, however, has been US-based and concerned primarily with TMT effects on organizational outcomes. The present study aims to expand this literature by examining the antecedents of top team composition in the context of macro-level economic change in a late-industrializing country. The post-1980 trade and market reforms in Turkey provided the empirical setting. Drawing upon the literatures on TMT and chief executive characteristics together with punctuated equilibrium models of change and institutional theory, the article develops the argument that which firm-level factors affect which attributes of TMT formations varies across the early and late stages of economic liberalization. Results of the empirical investigation of 71 of the largest industrial firms in Turkey broadly supported the hypotheses derived from this premise. In the early stages of economic liberalization the average age and average organizational tenure of TMTs were related to the export orientation of firms, whereas in later stages, firm performance became a major predictor of these team attributes. Educational background characteristics of teams appeared to be under stronger institutional pressures, altering in different ways in the face of macro-level change
