Sleeper weeds are weeds at the early stage of invasion exotic species that have become naturalised and are highly likely to turn invasive in due course New Zealand has more naturalised exotic vascular plant species than natives many of which are considered sleeper weeds Biological control is more likely to succeed on weeds that have not yet fulfilled their invasive potential hence its significance in management of sleeper weeds Multitargeting is suggested here as a new approach for safe and effective management of multiple closely related invasive and sleeper weed species from groups not represented in the native flora using agents with a relatively wide host range While specifically targeting an invasive species in the group such agents could prevent closely related sleeper weeds from becoming a problem in the first place Thistles were used as a case study and strong support was found for the multitargeting approach Thus three nontarget less preferred thistle species were attacked and damaged by the biocontrol agent Rhinocyllus conicus more in the presence of its preferred host Carduus nutans (nodding thistle) than in its absence both in a field experiment and in a field survey

Dynamic Case

Entrepreneurship, as applied here, involves helping students develop an entrepreneurial mindset by working in a university-supported startup that lacks the artificiality of a simulation or the safety net of heavy financial subsidization. This article chronicles an organizational-wide change at a private Midwestern university and the development of a new “artifact”—the dynamic case study—to complement a new approach to business and entrepreneurial education. After reviewing the function of case studies in a teaching and research context, I consider this new kind of case study as a boundary object and means for making sense of early stage entrepreneurial activity.

Uncertainty and change are two features of modern project management. They strongly influence the project management needs to operate in such contexts. This is the case when a complete and accurate definition of the scope of a project is not available. Those situations require a project management approach capable of dealing with the special conditions that characterise said contexts. This study focuses on the application of the progressive elaboration approach and the Critical Chain method. We analysed the implementation process of the new procedure in a company that produces capital goods for the automotive industry. The work’s main focus is on the effect of this change from the multi-project perspective. We found that the change had a larger impact than was expected by the company. Firstly, we found that the new approach provided an opportunity to improve the performance of the company. Besides, the new approach uncovered significant problems that previously were ignored, as well as problems and obstacles to the change. Based on the results and findings of this work, we conclude that shifting to this kind of approach requires a global managerial perspective, and strong support from the management.

This study used the Segment Tracing Algorithm (STA) to extract lineaments from remotely sensed images. A computer program was then written to calculate the lineament densities and lengths. In Gaosong field, 3,233 lineaments were extracted based on a 200 m × 200 m grid size. The results indicate that most lineaments lengths are between 30 m and 50 m, and the number of lineaments within each cell ranges from 1 to 6. Areas with high distributions exist on both sides of the central region. According to the contour map of lineament length, the maximum lineament length is 380 m, and the minimum length is 30 m. The contours mainly extend in two directions, including NE and NW trends. This is consistent with the prominent NE and NW strike faults that prevail in the mining area. The results are similar to those obtained in the Machishui ore block, which has become a mine production area. High values of lineament length and density in the contour map of Gaosong field may be associated with hydrothermal tin mineralization in the study area. The results of this study potentially provide a new approach to mineral exploration in the early stage of geological prospecting.

Abstract Inclusion of cerium (Ce) oxide particles as an abrasive into chemical mechanical planarization (CMP) slurries has become popular for wafer fabs below the 45nm technology node due to better polishing quality and improved CMP selectivity. Transmission electron microscopy (TEM) has difficulties finding and identifying Ce-oxide residuals due to the limited region of analysis unless dedicated efforts to search for them are employed. This article presents a case study that proved the concept in which physical evidence of Ce-rich particles was directly identified by analytical TEM during a CMP tool qualification in the early stage of 20nm node technology development. This justifies the need to setup in-fab monitoring for trace amounts of CMP residuals in Si-based wafer foundries. The fact that Cr resided right above the Ce-O particle cluster, further proved that the Ce-O particles were from the wafer and not introduced during the sample preparation.

Governance Disclosure

AbstractOver the last decades, Benefit Corporations arouse as a new corporate structure, alternative to traditional ones and pointing to offer a new approach to the management of business and sustainability issues. These companies' activities are statutory aimed at bridging for-profit and no-profit activities; thus, they intentionally and statutory pursue economic purposes together with social and environmental ones, to create a positive impact on economy, society and environment. Even though, Italian and other national laws set some specific disclosure duties for Benefit Corporations, especially in terms of Environmental, Social and Governance (ESG) issues, the literature still calls for further research on the topic. Therefore, this paper is aimed at contributing to bridge this gap, investigating the way Italian Benefit Corporations approach ESG disclosure. To this end, an exploratory analysis has been conducted, implementing a qualitative method, based on a multiple case study strategy. Even though the descriptive nature of the study, the achieved findings pointed out that the Benefit Corporation structure not necessarily implies a better approach to ESG.

Cities and nations worldwide are pledging to energy and carbon neutral objectives that imply a huge contribution from buildings. High-performance targets, either zero energy or zero carbon, are typically difficult to be reached by single buildings, but groups of properly-managed buildings might reach these ambitious goals. For this purpose we need tools and experiences to model, monitor, manage and optimize buildings and their neighborhood-level systems. The paper describes the activities pursued for the deployment of an advanced energy management system for a multi-carrier energy grid of an existing neighborhood in the area of Milan. The activities included: (i) development of a detailed monitoring plan, (ii) deployment of the monitoring plan, (iii) development of a virtual model of the neighborhood and simulation of the energy performance. Comparisons against early-stage energy monitoring data proved promising and the generation system showed high efficiency (EER equal to 5.84), to be further exploited.
