Pulsed laser deposition films from a Ba2FeMoO6 target onto SrTiO3[001]: Chemical and magnetic inhomogeneity.

Pulsed laser deposition films from Ba2FeMoO6 (BFMO) targets onto SrTiO3[001] (STO) substrates have been reported previously to have non-zero magnetism at 300 K, a majority of magnetic ordering at 240 K that is less than the 370 K ordering temperature of polycrystalline BFMO, and suppressed saturation magnetization compared to polycrystalline BFMO. To interrogate these previously reported observations of BFMO on STO, we have used a combination of x-ray diffraction, atomic force microscopy, x-ray and neutron reflectivity, and x-ray photoelectron spectroscopy that shows inhomogeneities. The present results show off-stoichiometry on the A-site by incorporation of Sr from the substrate and on the B-site to have %Fe/%Mo > 1 by evolution of BaMoO4. There is an enhanced ordering temperature and magnetic response nearer to the SrTiO3 interface compared to the air interface. Depth dependent strain and microstructure are needed to explain the magnetic response. Holistic considerations and implications are also discussed.

Measurement of band offsets in Y2O3/InGaZnO4 heterojunctions.

The valence band discontinuity (ΔE(v)) of Y2O3/InGaZnO4 (IGZO) heterojunctions was measured by a core-level photoemission method. The Y2O3 exhibited a band gap of -6.27 eV from absorption measurements. A value of ΔE(v) = 0.44 ± 0.21 eV was obtained by using the Ga 2p3/2, Zn 2p3/2 and in 3d5/2 energy levels as references. Given the experimental bandgap of 3.2 eV for the IGZO, this would indicate a conduction band offset ΔE(c) of - 2.63 eV in the Y2O3/IGZO heterostructures and a nested interface band alignment.

Mastering the management system.

Companies have always found it hard to balance pressing operational concerns with long-term strategic priorities. The tension is critical: World-class processes won't lead to success without the right strategic direction, and the best strategy in the world will get nowhere without strong operations to execute it. In this article, Kaplan, of Harvard Business School, and Norton, founder and director of the Palladium Group, explain how to effectively manage both strategy and operations by linking them tightly in a closed-loop management system. The system comprises five stages, beginning with strategy development, which springs from a company's mission, vision, and value statements, and from an analysis of its strengths, weaknesses, and competitive environment. In the next stage, managers translate the strategy into objectives and initiatives with strategy maps, which organize objectives by themes, and balanced scorecards, which link objectives to performance metrics. Stage three involves creating an operational plan to accomplish the objectives and initiatives; it includes targeting process improvements and preparing sales, resource, and capacity plans and dynamic budgets. Managers then put plans into action, monitoring their effectiveness in stage four. They review operational, environmental, and competitive data; assess progress; and identify barriers to execution. In the final stage, they test the strategy, analyzing cost, profitability, and correlations between strategy and performance. If their underlying assumptions appear faulty, they update the strategy, beginning another loop. The authors present not only a comprehensive blueprint for successful strategy execution but also a managerial tool kit, illustrated with examples from HSBC Rail, Cigna Property and Casualty, and Store 24. The kit incorporates leading management experts' frameworks, outlining where they fit into the management cycle.

Pediatrician characteristics associated with child abuse identification and reporting: results from a national survey of pediatricians.

Pediatrician experience with child protective services (CPS) and factors associated with identifying and reporting suspected child physical abuse were examined by a survey of members of the American Academy of Pediatrics (AAP). Respondents provided information about their demographics and experience, attitudes and practices with child abuse. They indicated their diagnosis and management of a child in a purposely ambiguous clinical vignette. Pediatricians who had received recent child abuse education were more confident in their ability to identify and manage child abuse. High confidence in ability to manage child abuse and positive attitude about domestic violence screening and value of anticipatory guidance predicted that pediatricians would have high suspicion that the child in the vignette was abused and that they would report the child to CPS. Future efforts to improve medical intervention in child abuse should focus on physician attitudes and experience, as well as cognitive factors.

How to implement a new strategy without disrupting your organization.

Throughout most of modern busi ness history, corporations have attempted to unlock value by matching their structures to their strategies: Centralization by function. Decentralization by product category or geographic region. Matrix organizations that attempt both at once. Virtual organizations. Networked organizations. Velcro organizations. But none of these approaches has worked very well. Restructuring churn is expensive, and new structures often create new organizational problems that are as troublesome as the ones they try to solve. It takes time for employees to adapt to them, they create legacy systems that refuse to die, and a great deal of tacit knowledge gets lost in the process. Given the costs and difficulties involved in finding structural ways to unlock value, it's fair to raise the question: Is structural change the right tool for the job? The answer is usually no, Kaplan and Norton contend. It's far less disruptive to choose an organizational design that works without major conflicts and then design a customized strategic system to align that structure to the strategy. A management system based on the balanced scorecard framework is the best way to align strategy and structure, the authors suggest. Managers can use the tools of the framework to drive their unit's performance: strategy maps to define and communicate the company's value proposition and the scorecard to implement and monitor the strategy. In this article, the originators of the balanced scorecard describe how two hugely different organizations--DuPont and the Royal Canadian Mounted Police-used corporate scorecards and strategy maps organized around strategic themes to realize the enormous value that their portfolios of assets, people, and skills represented. As a result, they did not have to endure a painful series of changes that simply replaced one rigid structure with another.

The office of strategy management.

There is a disconnect in most companies between strategy formulation and strategy execution. On average, 95% of a company's employees are unaware of, or do not understand, its strategy. If employees are unaware of the strategy, they surely cannot help the organization implement it effectively. It doesn't have to be like this. For the past 15 years, the authors have studied companies that achieved performance breakthroughs by adopting the Balanced Scorecard and its associated tools to help them better communicate strategy to their employees and to guide and monitor the execution of that strategy. Some companies, of course, have achieved better, longer-lasting improvements than others. The organizations that have managed to sustain their strategic focus have typically established a new corporate-level unit to oversee all activities related to strategy: an office of strategy management (OS M). The OSM, in effect, acts as the CEO's chief of staff. It coordinates an array of tasks: communicating corporate strategy; ensuring that enterprise-level plans are translated into the plans of the various units and departments; executing strategic initiatives to deliver on the grand design; aligning employees' plans for competency development with strategic objectives; and testing and adapting the strategy to stay abreast of the competition. The OSM does not do all the work, but it facilitates the processes so that strategy is executed in an integrated fashion across the enterprise. Although the companies that Kaplan and Norton studied use the Balanced Scorecard as the framework for their strategy management systems, the authors say the lessons of the OSM are applicable even to companies that do not use it.

The passive-aggressive organization.

Passive-aggressive organizations are friendly places to work: People are congenial, conflict is rare, and consensus is easy to reach. But, at the end of the day, even the best proposals fail to gain traction, and a company can go nowhere so imperturbably that it's easy to pretend everything is fine. Such companies are not necessarily saddled with mulishly passive-aggressive employees. Rather, they are filled with mostly well-intentioned people who are the victirms of flawed processes and policies. Commonly, a growing company's halfhearted or poorly thought-out attempts to decentralize give rise to multiple layers of managers, whose authority for making decisions becomes increasingly unclear. Some managers, as a result, hang back, while others won't own up to the calls they've made, inviting colleagues to second-guess or overturn the decisions. In such organizations, information does not circulate freely, and that makes it difficult for workers to understand the impact of their actions on company performance and for managers to correctly appraise employees' value to the organization. A failure to accurately match incentives to performance stifles initiative, and people do just enough to get by. Breaking free from this pattern is hard; a long history of seeing corporate initiatives ignored and then fade away tends to make people cynical. Often it's best to bring in an outsider to signal that this time things will be different. He or she will need to address every obstacle all at once: clarify decision rights; see to it that decisions stick; and reward people for sharing information and adding value, not for successfully negotiating corporate politics. If those steps are not taken, it's only a matter of time before the diseased elements of a passive-aggressive organization overwhelm the remaining healthy ones and drive the company into financial distress.

Measuring the strategic readiness of intangible assets.

Measuring the value of intangible assets such as company culture, knowledge management systems, and employees' skills is the holy grail of accounting. Executives know that these intangibles, being hard to imitate, are powerful sources of sustainable competitive advantage. If managers could measure them, they could manage the company's competitive position more easily and accurately. In one sense, the challenge is impossible. Intangible assets are unlike financial and physical resources in that their value depends on how well they serve the organizations that own them. But while this prevents an independent valuation of intangible assets, it also points to an altogether different approach for assessing their worth. In this article, the creators of the Balanced Scorecard draw on its tools and framework--in particular, a tool called the strategy map--to present a step-by-step way to determine "strategic readiness," which refers to the alignment of an organization's human, information, and organization capital with its strategy. In the method the authors describe, the firm identifies the processes most critical to creating and delivering its value proposition and determines the human, information, and organization capital the processes require. Some managers shy away from measuring intangible assets because they seem so subjective. But by using the systematic approaches set out in this article, companies can now measure what they want, rather than wanting only what they can currently measure.

X-ray microdiffraction study of growth modes and crystallographic tilts in oxide films on metal substrates.

The crystallographic texture of thin-film coatings plays an essential role in determining such diverse materials properties as wear resistance, recording density in magnetic media and electrical transport in superconductors. Typically, X-ray pole figures provide a macroscopically averaged description of texture, and electron backscattering provides spatially resolved surface measurements. In this study, we have used focused, polychromatic synchrotron X-ray microbeams to penetrate multilayer materials and simultaneously characterize the local structure, orientation and strain tensor of different heteroepitaxial layers with submicrometre resolution. Grain-by-grain microstructural studies of cerium oxide films grown on textured nickel foils reveal two distinct kinetic growth regimes on vicinal surfaces: ledge growth at elevated temperatures and island growth at lower temperatures. In addition, a combinatorial approach reveals that crystallographic tilting associated with these complex interfaces is qualitatively described by a simple geometrical model applicable to brittle films on ductile substrates. The sensitivity of conducting percolation paths to tilt-induced texture improvement is demonstrated.
