Organizational Form and the Economic Impact of Corporate New Product Strategies
No full textThis paper examines the role of organizational form in explaining the economic impact of corporate new product strategies. I find that the wealth effects associated with the announcements of new product introductions are more favorable for introducing firms with focused activities than for those with diversified activities. The results hold even after controlling for other factors suggested in the literature that could affect the value of new product introductions. The findings in this study suggest that the efficient investment hypothesis dominates the internal capital markets hypothesis in terms of the net economic impact of new product introductions on the introducing firms.

Our work is everywhere an illustrated oral history of queer & trans resistance
No full text"A visually stunning graphic non-fiction book on queer and trans resistance. Over the past ten years, we have witnessed the rise of queer and trans communities that have defied and challenged those who have historically opposed them. Through bold, symbolic imagery and surrealist, overlapping landscapes, queer illustrator and curator Syan Rose shines a light on the faces and voices of these diverse, amorphous, messy, real, and imagined queer and trans communities. In their own words, queer and trans organizers, artists, healers, comrades, and leaders speak honestly and authentically about their own experiences with power, love, pain, and magic to create a textured and nuanced portrait of queer and trans realities in America. The many themes include Black femme mental health, Pacific Islander authorship, fat queer performance art, disability and health care practice, sex worker activism, and much more. Accompanying the narratives are Rose's startling and sinuous images that brings these leaders' words to visual life. Our Work Is Everywhere is a graphic non-fiction book that underscores the brilliance and passion of queer and trans resistance. Includes a foreword by Lambda Literary Award-winning author and activist Leah Lakshmi Piepzna-Samarasinha, author of Care Work : Dreaming Disability Justice."-
Conception Originality of the Epoch and the Personality in the Poem by Khasyr Syan-Belgin «Fighter Orphan» (1935 )
No full textThe article is devoted to the study of the early poetry by Khasyr Syan-Belgin. In his early poetry he criticizes the social conditions surrounding people in the pre-Soviet era, putting social issues in the forefront. In the poem «Өnchn bөk» ("Fighter orphan") artistic conception of personality reveals the strength of national character in the history of the Kalmyk people. Created by the poet the conception of personality includes the basic traits of a true national hero, a loner hero with a new outlook, acting against the social system. Carefully designed and recreated the era of artistic painting and its ideological content confirms the importance of issues raised by the author in consonance with the time of his creative development
The Valuation of New Product Introductions under Uncertain Competition: A Real Option Approach
No full textDifferential identity of Filopodia and Tunneling Nanotubes revealed by the opposite functions of actin regulatory complexes
No full textTunneling Nanotubes (TNTs) are actin enriched filopodia-like protrusions that play a pivotal role in long-range intercellular communication. Different pathogens use TNT-like structures as "freeways" to propagate across cells. TNTs are also implicated in cancer and neurodegenerative diseases, making them promising therapeutic targets. Understanding the mechanism of their formation, and their relation with filopodia is of fundamental importance to uncover their physiological function, particularly since filopodia, differently from TNTs, are not able to mediate transfer of cargo between distant cells. Here we studied different regulatory complexes of actin, which play a role in the formation of both these structures. We demonstrate that the filopodia-promoting CDC42/IRSp53/VASP network negatively regulates TNT formation and impairs TNT-mediated intercellular vesicle transfer. Conversely, elevation of Eps8, an actin regulatory protein that inhibits the extension of filopodia in neurons, increases TNT formation. Notably, Eps8-mediated TNT induction requires Eps8 bundling but not its capping activity. Thus, despite their structural similarities, filopodia and TNTs form through distinct molecular mechanisms. Our results further suggest that a switch in the molecular composition in common actin regulatory complexes is critical in driving the formation of either type of membrane protrusion
Development of a manufacturing engineering system for the motor industry : executive summary
No full textManufacturing Engineering is concerned with converting a product specification
into the most appropriate method of manufacture to produce the product to the
correct cost and quality. Lack of integration and 'over the wall' engineering
between design and manufacturing engineering adds to the time and cost of
product development, and has significant effects on the subsequent cost and quality
of the product. Because of the size and complexity of manufacturing engineering
within the motor industry, the task is often divided between disparate, isolated,
departments that traditionally have their own goals and objectives, supported by
different business processes and systems. The adverse effects of the lack of
integration between design and manufacturing engineering re-emerge within
manufacturing engineering itself.
As a part of this research, the author analysed the existing information flows
through manufacturing engineering within Rover Group, and showed that the
business processes and systems generated a high duplication of effort and data, and
reinforced functional demarcation between the departments. The new Rover
Integrated Manufacturing Engineering System (RIMES) has been developed to
address these issues. RIMES has been developed using TQM techniques and
evolutionary delivery, new to Rover, to involve the manufacturing engineering
customer in all aspects of business analysis and system development. The resultant
system deliverables have therefore more closely met the customer requirements
and have consequently been implemented with greater customer support. The
subsequent changes to manufacturing engineering culture have been promoted
from within manufacturing engineering, with the RIMES system acting as a lever
for the change.
The research has been primarily concerned with the analysis and development of
appropriate solutions in three main areas: integration of design and manufacturing
engineering, change control procedures to maintain data integrity, and business
processes to improve efficiency of manufacturing engineering and the quality of its
output. These are all issues that are important for supporting concurrent
engineering but were found not to have been adequately addressed, either in the
research literature or in commercial systems, for applications involving large,
complex products.
The new system provides support for the electronic integration of design and
manufacturing engineering information, which is based on a technique developed
that combines data 'push' and 'pull' principles, and enables the efficient
communication of product specification to manufacturing engineering. It provides
a single system and repository of manufacturing engineering knowledge, a common
fundamental business process, and a common and consistent way of presenting
manufacturing engineering information and reports. Concurrent engineering is
promoted through early availability of information for downstream processes and
strict change control procedures have been developed to maintain data integrity.
The previously disparate departments of process engineering and industrial
engineering are now working concurrently from the same data which has improved
the accuracy, consistency and understanding of information both internally and in
external reporting. The time to market has been reduced because product
specification information is provided earlier and simultaneously to all
manufacturing engineering functions. The manufacturing engineering process and
its output have been redesigned. New working methods introduced through the
RIMES system have promoted reorganisation and the elimination of demarcation
within manufacturing engineering to further facilitate concurrent engineering.
Newly designed multi media forms for communication of process information to
manufacturing, developed in consultation with the RIMES user community, has
promoted team working on the shop-floor
Distributed routing and task allocation in multicomputer systems.
No full textIn this dissertation, we propose and analyze several strategies for routing and task allocation in multicomputer systems. The reduction and elimination of looping effects in computer networks is investigated. It is shown that the network's adaptability is improved by incorporating more information in routing messages. Depending on the network structure, the order of a routing strategy required for each node to eliminate looping completely can be determined. Routing in multicomputer networks with regular topology is also addressed. We present a systematic method for wrapping hexagonal meshes to achieve the homogeneity of the network and propose a new addressing scheme for wrapped H-meshes. Efficient routing and broadcasting algorithms under the new addressing scheme are developed. In addition, we develop two fault-tolerant routing schemes for hypercube multicomputers on the basis of depth-first search and network delay tables. An assignment from a task graph to a processor graph is said to be acceptable if every two adjacent task nodes are assigned to two processor nodes whose distance from each other is no more than a prespecified integer value. We address the problem of obtaining the number of acceptable task assignments for given task and processor graphs, and use it to simplify state-space search as well as reduce the size of the state-space to be searched. Two subcube allocation strategies, the buddy strategy using the buddy system and the GC strategy using the binary reflected Gray code, are investigated. Both strategies are proven to be statically optimal. We show that the number of subcubes recognizable by the GC strategy is twice that recognizable by the buddy strategy. Furthermore, we prove that the GC strategy is optimal in terms of the subcube recognition ability of a sequential search. A tight upper bond for the number of Gray codes required for complete subcube recognition is derived. Also, we propose the procedure for task migration under the GC strategy to eliminate fragmentation in a hypercube. We drive the goal configuration, the node-mapping between the source and destination subcubes, and a shortest deadlock-free routing scheme for task migration.PhDComputer scienceUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/162025/1/8907010.pd

No full textThis article is devoted to the analysis of Kazakhstan’s transit potential in the Silk Road Economic Belt. The transit potential of the country is part of the market infrastructure that must be developed for the successful functioning of the entire economy of the country. Kazakhstan is one of the largest countries in the world that has no access to the sea, but it has the capacity and should develop its transit and transport potential. The author studies opportunities, problems and benefits of the country from use of the transit potential, shows the real need for its effective realization. In conditions of globalization of world economy transit becomes the most important condition for country’s active participation in the international trade, a factor of development of transport branch and a source of replenishment of the state budget. Effective realization of transit potential of the RK in the international transport system is promoted by the international transport corridors passing through the territory of the country diversely. Important advantage of transit through the RK territory is the stable political situation and favorable investment climate. Nowadays, transit potential of Kazakhstan is not involved fully.
Key words: transit potential, transport corridors, Eurasian integration, international trade. China’s initiative, the economic belt of the Silk Road is a project that enables Kazakhstan to become a full participant in international transportation at the present time
