The Reluctant President.

Coaching CEO successor candidates is challenging and deeply nuanced in the best of circumstances. The stakes rise exponentially when the sitting CEO owns the company, resents having "anointed" an eventual successor, and has been phenomenally successful despite the bruising effects of his narcissism and toxic micromanagement. This case study describes how a data-driven, insight-oriented coaching methodology helped the CEO candidate accelerate his effectiveness, instill hope in the organization, and forge a more stable relationship with the CEO--a sufficiently functional relationship for the future CEO to decide to remain with the company. Furthermore, this work highlights the importance of clinical skills and 3 coaching meta principles (traction, trust, and truth-telling). Finally, this longer term coaching engagement illustrates the dynamic role shift from coach to trusted advisor. Through this deepened relationship, coaching gains were consolidated and an objective sounding board was retained for both the CEO and his eventual successor.

肉桂精油抗氧化性能及清除自由基能力的研究

对肉桂精油(CEO)的抗氧化和清除游离基活性的比较是基于总体抗氧化能力、清除超氧阴离子自由基能力、清除羟基自由基能力、抗亚油酸脂质过氧化能力、清除DPPH自由基5个方面,并与其他的合成抗氧化剂如BHT、PG做比较。实验结果表明,在一定浓度范围内,CEO的羟自由基清除能力强于BHT和PG;清除超氧阴离子自由基的能力强于PG;清除DPPH自由基能力、抗氧化活性比BHT和PG弱;CEO抑制亚油酸的过氧化能力比BHT和PG略弱。实验表明了CEO在某些方面具有良好的抗氧化效果。     

Relationship between Chief Executive Officer characteristics and corporate environmental information disclosure in Thailand

This study focuses on the influence of Chief Executive Officer (CEO) characteristics on environmental information disclosure (EID) in the annual reports of companies listed on the Stock Exchange of Thailand. A regression analysis method is used to explore the relationship between CEO characteristics and corporate environmental disclosure. Pollution-intensive companies are taken as the samples in this study. Results show that financial expertise, educational level, and tenure of CEOs are positively correlated with corporate EID. By contrast, age or gender of CEOs is insignificantly related to EID.     

Strategic maintenance-management in Nigerian industries

A developing society needs to adapt to change and foster creativity. In the pursuit of continual improvement (e.g., reducing fossil-fuel consumption and waste, better service performance, greater availability and improved reliability), implementing wise maintenance-schedules is essential for contemporary organisations. Several studies of a wide range of Nigerian industries indicate that indigenous low availability and low productivity are endemic. The resulting closure of some of these industries has triggered off a realisation of the strategic challenges in maintenance management. In addition, the increasingly-competitive business environment in Nigeria has raised the strategic importance of maintenance functions, especially in organisations with significant investments in physical assets. Five strategic aspects of maintenance management have been identified, namely: maintenance methodology; support processes; organisation and work structuring; comparable culture; and general management policy. Three factors that permeate these dimensions are wise leadership, excellent communications and an understanding of the human factors involved.     

Technical note Pitting corrosion of steel pipeline in oil–water–gas multiphase flow system

Abstract

Severe pitting corrosion occurred in a horizontal steel pipeline used to transport multiphase fluid, including water, oil, and natural gas, after 2 months of service. The pitting corrosion rate was up to 42 mm/year. Chemical analysis, X-ray diffractometry, and EDAX showed that the corrosion products mainly consisted of Fe₉ S₈, FeCO₃ , and NaCl. Calcium containing inclusions were also found in the matrix of the steel, which may accelerate corrosion. The early failure was attributed to the high proportion of water, the slow flow velocity, and the use of unqualified material.

Crystal Energy Optimization Algorithm

Nature has always been a muse for those who dream in art or science. As it goes, optimization algorithms inspired by nature have been widely used to solve various scientific and engineering problems because of their intelligence and simplicity. As a novel nature‐inspired algorithm, the crystal energy optimizer (CEO) is proposed in this article. The proposed CEO is motivated by the following general observation on lake freezing in nature: the dynamics of crystals have possession of parallelism, openness, local interactivity, and self‐organization. It stimulates us to extend a crystal dynamic model in physics to a generalized crystal energy optimizer for traveling salesman problems, so as to exploit the advantages of crystal dynamic system and to realize the aforementioned purposes. The proposed CEO has these advantages: (1) it has the ability to perform large‐scale distributed parallel optimization; (2) it can converge and avoid local optimum; and (3) it is flexible and easy to adapt to a wide range of optimization problems.     

The impact of transformational CEOs on the performance of small- to medium-sized firms: Does organizational context matter?

Although theory suggests that CEOs who engage in transformational leadership should have a positive effect on firm performance, most empirical examinations using data drawn from larger firms have failed to find support for this linkage. Given that the organizational complexity associated with larger firms has been viewed as a central obstacle to establishing this important link, the authors examined the impact of CEO transformational leadership on firm performance in smaller, privately held firms. After first explaining why the less complex context of these firms provides a setting for transformational CEOs to play a more direct role in enhancing firm performance, they then further clarified the nature of this link by hypothesizing 3 contingencies that they argued are particularly salient: firm size, CEO founder status (founder or nonfounder), and CEO tenure. Results from a multisource survey of CEOs and their top management teams in 121 firms and 2 time-lagged measures of performance, 1 objective and 1 perceived, provided consistent support for these hypotheses.

上市公司治理结构、企业绩效与总经理更换

为了研究导致我国上市公司总经理更换的影响因素,对总经理更换、公司治理结构以及企业绩效之间的关系进行了实证分析.基于我国上市公司1995～2003年的面板数据,首次利用随机效应Probit模型,按照总经理更换的不同类型进行了实证分析.研究发现,总经理被迫更换概率与企业绩效显著相关,但常规更换则不受此影响.另外,公司治理结构、企业绩效与总经理被迫更换概率有交互效应.企业的法人股东有积极性对经理人员实施监督和约束,在企业绩效下滑时更换总经理,但总经理兼任董事长的情况下,这种影响大为减弱.     

壳聚糖-肉桂精油复合涂膜的制备及其对核桃贮藏品质的影响

目的 研究壳聚糖（Chitosan,CS）浓度和肉桂精油（Cinnamon Essential Oil,CEO）添加量对复合膜性能（力学性能、透氧率、吸湿率、抗氧化性）的影响及最佳复合涂膜对核桃贮藏品质的作用效果。方法 采用不同质量分数（1%、1.5%、2%）的CS与不同质量分数（0.1%、0.2%、0.3%、0.4%）的CEO制备复合涂膜，对涂膜的各项性能进行表征，采用最佳比例的复合涂膜处理核桃，测定核桃在贮藏期间的营养及氧化相关指标的变化。结果 质量分数为1.5%的CS和质量分数为0.3%的CEO制备的复合膜具备良好的机械与抗氧化性能，经过涂膜处理后的核桃相较于对照组和纯CS处理组能够有效保持核桃在贮藏期间含水量、可溶性蛋白、脂肪的含量及较高的过氧化物酶（Peroxidase,POD）活性；同时抑制了核桃在贮藏期间酸价、丙二醛含量、多酚氧化酶（Polyphenol Oxidase,PPO）活性的增加。结论 添加CEO能够有效提升壳聚糖涂膜的性能，最佳比例制备的CS-CEO复合涂膜可以较好地保持核桃在贮藏期间的营养与抗氧化品质。
