Nuts are high in fat but have a fatty acid profile that may be beneficial in relation to risk of coronary heart disease. Nuts also contain other potentially cardioprotective constituents including phytosterols, tocopherols and squalene. In the present study, the total oil content, peroxide value, composition of fatty acids, tocopherols, phytosterols and squalene content were determined in the oil extracted from freshly ground walnuts, almonds, peanuts, hazelnuts and the macadamia nut. The total oil content of the nuts ranged from 37.9 to 59.2%, while the peroxide values ranged from 0.19 to 0.43 meq O2/kg oil. The main monounsaturated fatty acid was oleic acid (C18:1) with substantial levels of palmitoleic acid (C16:1) present in the macadamia nut. The main polyunsaturated fatty acids present were linoleic acid (C18:2) and linolenic acid (C18:3). alpha-Tocopherol was the most prevalent tocopherol except in walnuts. The levels of squalene detected ranged from 9.4 to 186.4 microg/g. beta-Sitosterol was the most abundant sterol, ranging in concentration from 991.2 to 2071.7 microg/g oil. Campesterol and stigmasterol were also present in significant concentrations. Our data indicate that all five nuts are a good source of monounsaturated fatty acid, tocopherols, squalene and phytosterols.

Nuts contain bioactive constituents that elicit cardio-protective effects including phytosterols, tocopherols and squalene. The objective of the present study was to determine the total oil content, peroxide value, fatty acid composition and levels of tocopherols, squalene and phytosterols in oil extracted from freshly ground brazil, pecan, pine, pistachio and cashew nuts. The total oil content of the nuts ranged from 40.4 to 60.8% (w/w) while the peroxide values ranged from 0.14 to 0.22 mEq O2/kg oil. The most abundant monounsaturated fatty acid was oleic acid (C18:1), while linoleic acid (C18:2) was the most prevalent polyunsaturated fatty acid. The levels of total tocopherols ranged from 60.8 to 291.0 mg/g. Squalene ranged from 39.5 mg/g oil in the pine nut to 1377.8 mg/g oil in the brazil nut. beta-Sitosterol was the most prevalent phytosterol, ranging in concentration from 1325.4 to 4685.9 mg/g oil. In conclusion, the present data indicate that nuts are a good dietary source of unsaturated fatty acids, tocopherols, squalene and phytosterols.

In this study we argue that the approach to strategy formation reflects organizational and individual influences. The study, based on questionnaire responses from 359 firms, examines a number of organizational and individual factors influencing the type of strategy formation process adopted. The constructs of strategic posture, organization structure, management ownership, and Chief Executive Officer (CEO) experience are measured. Three models predicting strategy formation approaches are explored. First, an organizational model emphasizing the impact of strategic posture and organization structure is analyzed. Second, a model is tested dealing with CEO and top management team characteristics reflecting the effects of agency costs and experience base. Finally, an integrative model combining both organizational and individual factors is evaluated. The results highlight the importance of organizational factors and show, for instance, that entrepreneurial firms tend to adopt more formal strategic planning approaches, while conservative firms adopt more incremental approaches. In addition, both management shareholding and CEO experience are negatively related to formal strategic planning activities. IntroductionStrategy development has received renewed attention from both practitioners and scholars as environments become more competitive (Bettis and Hitt 1995) and as academics and consultants advocate the necessity of enhancing strategic thinking within firms (for example, Hamel and Prahalad 1994). One specific modality of strategy development, namely strategic planning, has received significant research attention.Dr. Gibbons is Jefferson Smurfit Professor of Corporate Planning at University College Dublin in Ireland. Current areas of research interest include strategy processes, firm-level technology policy, and corporate entrepreneurship.Dr. O'Connor is management consultant in the areas of strategy and operations management and also lectures at University College Dublin in these topics. Current areas of research interest include the strategy formation process, technology policy, entrepreneurship, and the strategic objectives adopted by high technology startup operations. *The authors thank the National Institute of Technology Management for assistance in making this research possible and Colm O'Gorman for helpful comments on an earlier version of this paper.The evaluation of the performance effects of strategic planning has been a central concern of researchers over the past three decades (for example, Brews and Hunt 1999;Bracker, Keats, and Pearson 1988;Robinson and Pearce 1984). While results have varied, evidence suggests that formal strategic planning is related to superior performance. For example, Schwenk and Schrader (1993) conducted a metaanalysis of studies into the effects of formal strategic planning on the financial performance of small firms and concluded that strategic planning has a significant, positive association with financial performance.
