How to Handle an Internal Venture? : The Effect of Relatedness on the Outcomes of Corporate Venturing

Budryk, Michal, Schmuck, Alice January 2014 (has links)
This paper uses event history analysis to investigate the effects of relatedness on three different outcomes of corporate venturing, identified as retention, termination, and spin-off. For this purpose, relatedness is defined as the degree to which the venture’s activity matches or overlaps with the parent’s activity. Drawing from literature on relational fit, we argue that highly related ventures would be retained, moderately related ones spun off, and unrelated ones would be probable candidates for termination. However, highly related ventures may be likely to pose internal threat to the parent, and consequently be candidates for termination for political reasons as well. This raises the average level of relatedness of terminated ventures above the average of spin-offs. The empirical findings derived from a sample consisting of 78 ventures launched and developed by a number of companies across the Swedish economy give support to our expectations. The highly related ventures were found to be either terminated or retained, moderately related ones were likely to be spun off, and unrelated ones typically faced termination. This supports our hypothesis that relatedness has an impact on how the internal venture is dealt with. We follow with implications for the practice of corporate venturing management.

Scheme-based theorem discovery and concept invention

Montano-Rivas, Omar January 2012 (has links)
In this thesis we describe an approach to automatically invent/explore new mathematical theories, with the goal of producing results comparable to those produced by humans, as represented, for example, in the libraries of the Isabelle proof assistant. Our approach is based on ‘schemes’, which are formulae in higher-order logic. We show that it is possible to automate the instantiation process of schemes to generate conjectures and definitions. We also show how the new definitions and the lemmata discovered during the exploration of a theory can be used, not only to help with the proof obligations during the exploration, but also to reduce redundancies inherent in most theory-formation systems. We exploit associative-commutative (AC) operators using ordered rewriting to avoid AC variations of the same instantiation. We implemented our ideas in an automated tool, called IsaScheme, which employs Knuth-Bendix completion and recent automatic inductive proof tools. We have evaluated our system in a theory of natural numbers and a theory of lists.

Biochemical and genetic analysis of RNA processing and decay

Ghazal, Ghada January 2009 (has links)
Gene expression is the conduit by which genetic information is connected into cellular phenotypes. Recently, it was shown that gene expression in mammalian cells is governed, at least in part, by the expression of short double stranded RNA (dsRNA). This mode of gene regulation is influenced by a large group of dsRNA binding proteins that could either stabilize or trigger the degradation of dsRNA. Indeed, double stranded RNA (dsRNA) specific ribonucleases (RNases) play an important role in regulating gene expression. In most eukaryotes, members of the dsRNA specific RNase III family trigger RNA degradation and initiate cellular immune response. Disruption of human . RNase III (Dicer) deregulates fetal gene expression and promotes the development of cancer. However, very little is known about the housekeeping function of eukaryotic RNase III and the mechanism by which they distinguish between exogenous and endogenous cellular RNA species. This thesis elucidates how dsRNAs are selected for cleavage and demonstrates their contribution to RNA metabolism in yeast as model eukaryote. Initially, the reactivity determinants of yeast RNase III (Rnt1p) were identified in vitro and used to study the global impact of Rnt1p on the processing of non-coding RNA. The results indicate that Rnt1p is required for the processing of all small nucleolar RNAs (snoRNAs) involved in rRNA methylation and identify a new role of Rnt1p in the processing of intronic snoRNAs. It was shown that Rnt1p cleavage helps to coordinate the expression of some ribosomal protein genes hosting intronic snoRNAs. Direct snoRNA processing from the pre-mRNA blocks the expression of the host gene, while delayed snoRNA processing from the excised intron allows the expression of both genes. In this way, the cell can carefully calibrate the amount of snoRNA and ribosomal proteins required for ribosome biogenesis. In addition, a global analysis of snoRNA processing identified new forms of Rnt1p cleavage signals that do not exhibit a conserved sequence motif but instead use a new RNA fold to recruit the enzyme to the cleavage site. This finding led to the conclusion that Rnt1p may use a wide combination of structural motifs to identify its substrates and thus increases the theoretical number of potential degradation targets in vivo . To evaluate this possibility, a new search for snoRNA independent Rnt1p cleavage targets was performed. Interestingly, many Rnt1p cleavage signals were identified in intergenic regions devoid of known RNA transcripts. In vivo , it was shown that Rnt1p induce the termination of non-polyadenylated transcripts and functions as a surveillance mechanism for transcription read-through. This finding directly links Rnt1p to the transcription machinery and provides a new mechanism for polyadenylation independent transcription termination. Together the work described in this thesis presents an example of how eukaryotic RNase III may identify its substrates and present a case study where transcription, RNA processing and stability are linked.

Impact of Clinician Expectations on Termination Status and Therapeutic Outcome

Connor, Dana R. 05 1900 (has links)
Given the high rates of premature termination in training clinics, research aimed at understanding client attrition is urgently needed. Recent investigations in this area have implicated expectations of psychotherapy as a strong predictor of premature termination; however, this phenomenon has only been studied from the perspective of client expectations to date. There is reason to believe clinician expectations for the duration and effectiveness of psychotherapy may further impact the likelihood of their clients terminating prematurely. This study sought to address this gap in the literature by examining the association of clinicians' expectations to clients' psychotherapy outcomes and termination status in a training clinic setting. Clinicians were found to hold significantly higher expectations for client improvement than would be expected, and these high expectations were found to be positively correlated with clinically significant change in clients. Implications for improving client retention and treatment outcome in training clinics are discussed.

Komparace právní úpravy zániku nájmu bytu v České republice a Polsku / A comparison of legal regulation of termination of flat lease in the Czech Republic and Poland

Hanusek, Viktor January 2015 (has links)
Housing is one of the basic needs of everyone. If this need is not satisfied, one does not feel safe. In fact, one suffers in other respects, does not have privacy and is not able to engage in other activities. There are various ways how to realize the need of housing. Nevertheless, the biggest limiting factor is the financial situation of the person. Therefore, the vast majority of the population lives in a leased flat these days. The lessee is in the position of the weaker party regarding the contract. Therefore, the law provides a special legal protection for the lessee. I decided to write a diploma thesis that would concern the housing law. It happened after passing optional subject called Housing law and I have gained valuable knowledge about legal issue of lease housing. Frankly, I was impressed by its dynamics and frequency. I chose a comparative topic thanks to my study abroad in Wrocław within the Erasmus programme. That programme provided me an access to Polish literature. Moreover, I had a great opportunity to consult the Polish law with lawyers teaching me at the University of Wrocław. The main aim of my diploma thesis is to analyse the ways of the legal regulation of termination of flat lease in the Czech Republic and Poland. This corresponds to the structure of the thesis. The first...

Exclusion And Withdrawal of Members And Cancellation of Their Membership In a Limited Liability Company Abstract This thesis aims to analyze current legislation of exclusion and withdrawal of members and cancellation of their membership in a limited liability company. Although comparing the current legislation with the previous one is not the purpose of the thesis, such comparison is provided in several places. The purpose is to show the same or, conversely, different features of both, particularly in relation to the applicability of existing case law and doctrinal interpretation. The work consists of three main chapters that form a coherent wholes. The first chapter is devoted to the withdrawal of a member of a limited liability company and is further divided into several sub-chapters. It deals with the legal aspects of the withdrawal of a member under the Czech legislativ. It describes in detail the various reasons of the withdrawal and also offers some suggestions de lege ferenda. The second chapter focuses on the exclusion of a shareholder of a limited liability company by the general meeting. It brings an analysis of legislation, describes the procedure of exclusion and analyzes the available case law. The third chapter, entitled "Termination of participation of a member of a limited liability company...

Zánik nájmu bytu / Apartment lease termination

Vacek, Aleš January 2016 (has links)
The diploma thesis is focused on the apartment lease termination. The goal of the thesis is to analyse legislation of the ways of apartment lease termination which are the most important in practice. Specifically it includes an agreement, an expiry of the period, a notice and a death of a lessee. Another goal of the thesis is to identify and aim at shortcomings of the current legislation and also to propose their suitable solutions. The thesis consists of introduction, three parts and conclusion. It draws information from legal regulations, legal literature, case law and other. The first part of the thesis deals with general characteristics of apartment lease and its termination. The legislation, basic features of apartment lease and its termination are described there and also the classification of the ways of apartment lease termination is done there. The second part of the thesis describes the ways of apartment lease termination except notice. At first the attention is concentrated on an agreement about apartment lease termination, mainly its form and consequences followed from a breach of the form. Then the thesis is focused on apartment lease termination by expiry of the period and also on renewal of lease which relates to it. Subsequently problems of a death of the lessee and the passage of...

Právní úkony vedoucí ke skončení pracovního poměru / Legal acts aimed at the termination of employment

Benešová, Anna January 2012 (has links)
Legal acts aimed at the termination of employment Abstract The aim of this thesis is to provide a comprehensive picture of the current and future new regulations on legal acts leading to the termination of employment. The thesis consists of seven chapters, each of them dealing with different issues. The first chapter is devoted to legal acts in general, to the employment relationship and its termination. It specifies what a legal act is and defines its requisites. The definition of the employment relationship and its termination are dealt with in its two subchapters. The second chapter concentrates on one of the legal acts leading to the termination of employment - the mutual termination agreement. This chapter consists of two subchapters, the first one specifying the requisites of the mutual termination agreement, the second one containing a concluding interpretation of this kind of agreement. The third chapter is devoted to the notice of termination of employment, the unilateral legal act resulting in the termination of the employment relationship. This chapter contains five subchapters. The first one deals with the notice period, mainly with its length, its course and its regulation in the conceptual amendment to the Czech Labour Code. The second subchapter concentrates on the notice of termination of...
