Emergent interorganizational forms intent on long-term competitive performanceat the network level are affecting markets and gaining scholarly attention.Whole networks are an example of such organizations. Managerial paradoxes resultfrom these informal, non-hierarchical structures when they seek long-term competitiveadvantage. Applying paradox theory and research on ambidexterity, we concludethat, counter intuitively, formalized governance is necessary to sustain informalcompetitive entity success. Contrary to traditional network theory, social capitalmechanisms and trust are not solely adequate. We examine challenges facing wholenetworks and propose three governance strategies to address them: (1) formalizedgovernance with adequate authority; (2) centralized leadership with decentralizeddecision-making; and (3) provisions for managing membership composition. Wediscuss implications for practitioners and scholars and suggest research paths forvalidating and extending this theory.

Recently, membrane distillation (MD) has emerged as a versatile technology for treating saline water and industrial wastewater. However, the long-term use of MD wets the polymeric membrane and prevents the membrane from working as a semi-permeable barrier. Currently, the concept of antiwetting interfaces has been utilized for reducing the wetting issue of MD. This review paper discusses the fundamentals and roles of surface energy and hierarchical structures on both the hydrophobic characteristics and wetting tolerance of MD membranes. Designing stable antiwetting interfaces with their basic working principle is illustrated with high scientific discussions. The capability of antiwetting surfaces in terms of their self-cleaning properties has also been demonstrated. This comprehensive review paper can be utilized as the fundamental basis for developing antiwetting surfaces to minimize fouling, as well as the wetting issue in the MD process.

This work describes a simple and cost-effective aqueous-phase synthesis of Cu nanowires with long-term stability. Chloride ions and branched polyethyleneimine (BPEI) were found to be of great importance to the formation and stabilization of Cu nanowires.

n the long-term development of human geography we can observe a tendency to combine ideas from an intradisciplinary debate and those imported from outside the discipline. It is profoundly influenced by a number of impulses from the rapidly changing world. This paper provides a brief survey of challenges for human geography setting them within the context of paradigmatic development and economic, social, cultural, environmental, political, and technological changes. It briefly focuses on the debates of human geographers what their discipline could or should study in the near future and how it could be done. Part of the paper is devoted to a few reflections of authors from the Visegrad Four countries concentrating attention to further direction of human geography. Human geography is unlikely to be characterised by a mono-paradigm dominance in the next few decades, but a discussion on how to find a common base for the integration of paradigms in geography is likely to continue. Changing hierarchical structures, significant modernization processes, as well as local, regional and global changes influencing space-time behavioural patterns of humans can be expected among the main sources of inspiration for the human geographic research.

The year 2000 Young Professionals Seminar focused on long-term intergenerational challenges. Water related problems are symptoms of complex and ultimately societal problems linked to human behaviour, political support and managerial and institutional structures. Although integrated water resources management is presented as a solution, it is not always well understood, and can create a sense of hopelessness among professionals. To make it operational requires long-term commitments among various professionals and the involvement of new actors. A number of key topics crystallised as needing further attention, including ethical dimensions in policy making, the development of a framework for a 'Future Generation Impact Assessment' (FGIA), and efforts to achieve true dialogue among stakeholders. Young water professionals must become more involved in political processes and take active part in institutional changes. Such engagement will require changes in the working environment facing many young professionals that causes frustration due to inefficient and conservative hierarchical structures and the lack of transparency

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.
