Li, Xi. "Mergers and acquisitions : takeover efficiency, social connection and acquisition performance". Thesis, Durham University, 2018. http://etheses.dur.ac.uk/12460/.

Abstract (sommario):
This thesis develops a composite index to evaluate takeover efficiency and deal quality, and then examines the impact of social connection on takeover process and acquisition performance with U.S mergers and acquisitions (M&A). Initially, Chapter 2 constructs a composite indicator (“M&A index”) to measure takeover efficiency and evaluate the overall deal quality based on stochastic frontier analysis. The M&A index is computed for each takeover transaction and standardised between 0 and 1. Deals with a higher M&A index imply higher takeover efficiency. The empirical results show that the M&A index is significantly and positively associated with the probability of deal completion and post-acquisition performance in the short run and even in the long run, indicating that the M&A index is effective and forward-looking indicator. Then Chapter 3 examines social connections between bidders and targets and its impact on acquisition premium. Consequently, acquirers, who are closely connected with targets, pay significantly lower premium and tend to use stock as the method of payment. The findings indicate that social connection enhances information transfer and reduces information asymmetry between connected firms. Therefore, acquirers with social connections have better access to target information and enhanced bargaining power in negotiations. Finally, Chapter 4 addresses the connection between acquirers and their M&A advisors. Investment banks are further classified into full-service advisors and boutique advisors. Consequently, it is found that acquirers are more likely to hire closely connected boutique advisors, especially domestic boutique advisors, in takeover deals while connections between bidding firms and full-service advisors reduces the probability of full-service banks being appointed. Moreover, boutique advisors, who have strong social linkage with bidders, serve the interests of bidders, negotiate lower acquisition premiums and deliver higher deal quality. In contrast, full-service banks act against the interests of the connected acquirers, leading to higher premiums paid and inferior long-run acquisition performance.

Abstract (sommario):
This study examines the effect of using toeholds in domestic and cross-border acquisitionprocesses on the bidder’s acquisition performance. The sample constitutes 1,701 acquisitionsof European listed firms over the period 2003-2016. Results reveal significant evidence of anadverse effect of toeholds on the bidder’s acquisition performance. However, in cross-borderacquisitions, the use of toeholds results on average in significantly higher abnormal returns.Finally, the use of toeholds is found to be more efficient in target countries with a civil-lawsystem compared to countries with a common-law system. Overall, these findings increase ourunderstanding of management actions about the application of toeholds as an acquisitionstrategy.

Abstract (sommario):
This project investigates acquisition of a new language by example. Syntax induction has been studied widely and the more complex syntax associated with Natural Language is difficult to induce without restrictions. Chomsky conjectured that natural languages are restricted by a Universal Grammar. English could be used as a Universal Grammar and Punjabi derived from it in a similar way as the acquisition of a first language. However, if English has already been acquired then Punjabi would be induced from English as a second language.

Abstract (sommario):
The research, informed by the knowledge based view of the firm, explores the relation between pre-acquisition alliances between acquirer and target and post-acquisition innovation performance. Pre-acquisition alliances are a rare event and the work draws on an original dataset, incorporating financial, mergers and acquisitions, patents, and business news databases. The sample consists of 269 high technology M&As with pre-acquisition alliances, which is then compared with a matched sample of acquisitions without prior alliances. The research adopts ‘doubly robust’ matching and average treatment effect models to observe the causal effect of acquisitions with pre-acquisition alliances on innovation performance. The results show that acquisitions following pre-acquisition alliance between acquirer and target differ substantially from the pool of acquisitions without any pre-acquisition alliances. Further, the study looks into the variety of knowledge motivations in pre-acquisition alliances, such as: alliances motivated by exploration and exploitation with different levels of intensity. The result reveals that a distinction between the intensity of exploration and exploitation better explains the result. The study also focuses on knowledge relatedness (in particular, technology similarity and complementarity) between firms involved in acquisitions both with and without pre-acquisition alliances and the role it plays in post-acquisition innovation performance. The result shows that the presence of technology similarity in firms involved in acquisitions with pre-acquisition alliances makes the integration process smoother and more efficient. Therefore, the performance outcome can be observed more rapidly in such cases than that of acquisitions without pre-acquisition alliances. Conversely, in cases with technology complementary between firms engaged in acquisitions with pre-acquisition alliances, we observe less negative impact on post-acquisition innovation performance. This research contributes towards bringing strategic management and the knowledge based view of the firm closer together by focusing on the role of knowledge as motivation for acquisition in pre-acquisition alliances. The results illustrate a better understanding of the relation and effectiveness of pre-acquisition alliances and innovation performance, and a clearer operationalisation of concepts of post-acquisition innovation performance. The study findings suggest that managers developing both acquisitions and alliances, should also consider pre-acquisition alliances, and bear in mind the different nature and levels of intensity in knowledge motivations and knowledge relatedness between acquirer and target as a factor influencing innovation performance.

Li, Lu. "The impact of pre-merger disclosure and acquisition experience on mergers and acquisitions". Thesis, Durham University, 2018. http://etheses.dur.ac.uk/12902/.

Testo completo
Abstract (sommario):
This thesis focuses on the effect of factors in the pre-acquisition planning stage on M&A outcomes. With three empirical chapters, the main findings provide compelling evidence that pre-acquisition factors are related to M&A fundamentals such as the motivation and incentives to carry out M&A transaction, and play significant roles in deal’s negotiation and post-acquisition integration. The first empirical chapter of this thesis investigates whether the voluntary disclosure at pre-acquisition issuance activities, i.e. the intended ‘use of proceeds’, has influence on subsequent M&A outcomes. The results show that firms disclosing acquisition intention at debt/equity issuance significantly raise more funds but fail to allocate capital efficiently on value-increasing M&A transactions. This evidence is consistent with the capital need theory. The second empirical chapter examines the wealth effect of mega corporate takeover and explores whether rich acquisition experience facilitate acquirers to generate shareholder value in mega-deals. The findings show that acquirer’s acquisition experience is positively related to mega-deals completion likelihood, stock performance in short- and long-run, and operating performance in the long-run following mega-mergers. The evidence indicates that acquirers are able to learn though experience and develop skills to deal with the complexity of mega-mergers. The final empirical chapter provides evidence on the relationship between target CEOs’ acquisition experience and takeover gains for target shareholders. The results show that target shareholders are likely to receive lower bid premiums and earn lower abnormal stock returns around deal announcement when they have a CEO with more acquisition experience. Additionally, target CEOs’ acquisition experience is positively related to stock payment. Our evidence suggests that more experienced target CEOs tend to bargain for more personal benefits related to the voting influence in the combined firm instead of helping their shareholders to gain bargaining advantage in the negotiation.

Abstract (sommario):

Based on Hofstede's findings, this study breaks down Kogut and Singh's index of cultural distance, examining implications for acquisition performance of each individual dimension. Hypotheses are formulated, and based on deal data covering 488 acquisitions with American companies as acquirers, tested through linear regression. We find support for a positive relationship between cultural distance of power distance and performance, and an inverse relationship between cultural distance of masculinity and performance. Significant results are not obtained for the remaining dimensions.

Abstract (sommario):
This thesis concerns the acquisition of newly developed production equipment in factories. Types of Manufacturing Technology Acquisition (MTA) can range from in-house development through to outright purchase from a supplier. MTA projects often fail because the new equipment fails to perform well enough or the expected financial benefits are not achieved. The purpose of this research has been to find out how to select the right manufacturing technology acquisition projects, and having chosen them, how to make them successful. Very little guidance on this subject was found in the literature. Therefore the approach taken was to adapt techniques widely used in the much more deeply researched field of New Product Development (NPD). The Success Factor method was applied by conducting interviews with managers in a number of factories to develop lists of factors thought to affect success or failure in their MTA projects. The Portfolio method from NPD was adapted to the case of managing a total MT`A budget, and developed through its use in three annual cycles of equipment acquisition in the researcher's Company. A formula for Expected Commercial Value in NPD was modified to become Expected Manufacturing Benefit, and tried out in practice. An important consideration in manufacturing equipment projects was discovered to be the replication of projects which had proved successful, and ways to incorporate this factor into the project selection procedure were developed. A detailed case study of a single project was carried out, which verified the validity of the findings at the level of a single project. This case study also revealed the considerable impact that corporate strategic events can have on technology acquisitions. This led to a case study on corporate strategy in the Company being carried out. Finally the findings were brought together to present a complete model for managing MTA.

Abstract (sommario):
The purpose of this project was to develop control software for a multi-spectral imaging system. The multi-spectral imaging system used by the colour Lab consists of a camera (Alta USB camera) and a filter (VariSpec liquid crystal tuneable filter). The camera and the filter were delivered by two different manufacturers and therefore have two separate stand-alone control programs. The fact that the hardware had to be controlled by two separate pieces of software meant that the image capturing procedure was very time-consuming and needed an unrealistic amount of user input. The project resulted in a C++ console program with all the required and necessary functionsas those provided by the individual software, camera and filter; and operated both the camera and the filter simultaneously and conveniently. The project was performed at the Norwegian colour Laboratory in Gjøvik University College.

Brink, Jaco. "Do large South African acquisitions result in post-acquisition improvements in cash flow returns?" Master's thesis, University of Cape Town, 2016. http://hdl.handle.net/11427/20978.

Testo completo
Abstract (sommario):
The purpose of this study is to evaluate whether South African acquisitions result in success, with success measured as post-acquisition improvements in cash flow returns. The reason for this approach is the view that a firm's intrinsic value is coupled to its long-term cash-generating ability. Post-acquisition change in cash flow returns for large acquisitions made by JSE-listed firms over the period 1995 - 2009 were analysed. Cash flow returns were measured as free cash flow to the firm over capital employed. This measurement of cash flow return is neutral to the firm's financing decision and capital structure, thus facilitating a comparison between different firms. Changes in annual cash flow returns were measured over the period covering five years preceding and five years following completion of acquisitions. The cash flow returns of the acquiring firms were compared to benchmark returns of firms in the same sector which did not undertake major acquisitions. The study found in 22 of 24 tests that the benchmarked post-acquisition cash flow returns and EBITDA returns were not significantly different in relation to the benchmarked pre-acquisition returns. However, in two tests which adjusted for operating leases and used total returns over the pre-acquisition and post-acquisition periods, it was found that the difference in returns were significant. The sample of eleven firms is relatively small and any inferences about South African acquisitions in general should therefore be approached with care. The divergence in results between the individual firms within the sample, as well as the outlined sensitivities of observed results lend further support for this cautionary approach. Despite the limited number of acquisitions that occurred over the period, this study should contribute towards a better understanding of the overall value proposition of large South African acquisitions, as well as provide impetus for related future research.

Abstract (sommario):
Through an investigation of the acquisition of feature geometric representations in first and second language acquisition, this dissertation demonstrates how the Feature Geometry theory contained in Universal Grammar actively guides and constrains the acquisition of segmental representations by children. In addition, it demonstrates how the mature feature geometry in a speaker's mental grammar restricts the range of nonnative phonemic contrasts that he or she will be sensitive to in the input and, hence, able to acquire as an L2 learner.
Three related areas of research are explored and integrated in this work: first, a theoretical study explores the feature-geometric representation of sonorant and non-sonorant laterals, based on their behavior in a variety of phonological processes cross-linguistically, and suggests that [lateral] is not a phonological feature, but rather that laterality is a phonetic property that derives from a specific feature-geometric representation; second, an experimental study investigates the acquisition of phonemic contrasts by English children and demonstrates that segmental representations are acquired in a uniform order that is consistent with properties of Feature Geometry; finally, a series of experimental studies examines the perception and acquisition of the English /l-r/, /b-v/, /p-f/, /f-v/ and /s-theta/ contrasts by native speakers of Japanese, Mandarin Chinese and Korean.
The findings from each of these studies are synthesized to obtain a comprehensive picture of how segmental representations are acquired and how this L1 knowledge impinges on the acquisition of L2 phonemes: it is argued that the monotonic acquisition of feature-geometric structure by young children restricts their sensitivity to particular non-native contrasts, and the continued operation of this existing feature geometry in adult speech perception constrains which non-native contrasts adult learners will be sensitive to in the L2 input and, therefore, capable of acquiring; the circumstances in which the native grammar facilitates perception of non-native contrasts and in which acquisition is possible are also discussed.

The pharmaceutical industry is now confronted with a discontinuous time period, especially in terms of its technology. In order to maintain their advantageous positions in the industry, pharmaceutical companies have to invest not only in internal R&D but also in external sources, since technologies in the industry are too broad to enable a company to cover all of the new technologies. Allotment of investment in internal and external R&D, however, is hard to determine; moreover, the selection of targets and styles of external technology acquisition by pharmaceutical companies requires deep deliberation on all the scientific and business aspects. In this thesis, I have analyzed the correlation between technology acquisition activities and the internal technological strength, or product development, in nine pharmaceutical companies in three countries: U.S., Japan, and Germany. Styles of technology acquisition deals vary among the three countries. German companies showed the most aggressive technology acquisition strategies in overall technology deals. U.S. companies exhibit strong technology acquisition strategies with prominent equity investment deals. Japanese companies were discreet about their technology acquisition deals, although they showed a similar degree of eagerness for product acquisition. The number of technology acquisition deals by Japanese companies, however, has increased during the past two or three years. A positive correlation between the number of all deals and product development (the number of pre-clinical drug candidates) was detected. On the other hand, there is no clear correlation between technology creation deals or technology frontier deals and product development. In order to assimilate the growing amount of external property, pharmaceutical companies must consider setting up an appropriate management organization because the deals between biotech enterprises and pharmaceutical companies involve dissimilar organizations in terms of culture, size, power, and expertise. I studied the organization of alliance management in Eli Lilly as an example.

Abstract (sommario):

PAN, Personal Area Network, may be described as the connection of personal devices, allowing information exchange over short ranges. This term is used on several of todays short range wireless technologies like Bluetooth, ZigBee, Infrared etc. In this thesis we look in to how Bluetooth as a PAN technology may be used to enrich context information to a person. Context is information that can be used to characterize the situation of an entity. It may be acquired in many ways, e.g. from user input (status in an IM client), sensed (temperature, location, heart rate), or derived (e.g. combination of location and time of day). Several scenarios showing the benefits of context aware computing will be presented, and proposals on how Bluetooth may fit in as an enabling technology will be evaluated. In the end, a design and implementation showing Bluetooth in context acquisition will be presented.

Al-Jabir, Shaikha. "Terminology-based knowledge acquisition". Thesis, University of Surrey, 1999. http://epubs.surrey.ac.uk/843300/.

Testo completo
Abstract (sommario):
A methodology for knowledge acquisition from terminology databases is presented. The methodology outlines how the content of a terminology database can be mapped onto a knowledge base with a minimum of human intervention. Typically, terms are defined and elaborated by terminologists by using sentences that have a common syntactic and semantic structure. It has been argued that in defining terms, terminologists use a local grammar and that this local grammar can be used to parse the definitions. The methodology has been implemented in a program called DEARSys (Definition Analysis and Representation System), that reads definition sentences and extracts new concepts and conceptual relations about the defined terms. The linguistic component of the system is a parser for the sublanguage of terminology definitions that analyses a definition into its logical form, which in turn is mapped onto a frame-based representation. The logical form is based on first-order logic (FOL) extended with untyped lambda calculus. Our approach is data-driven and domain independent; it has been applied to definitions of various domains. Experiments were conducted with human subjects to evaluate the information acquired by the system. The results of the preliminary evaluation were encouraging.

Spread-spectrum systems with large transmission bandwidth present significant challenges from the standpoint of achieving synchronization before communication commences. This research investigates a rapid acquisition procedure that exploits the multipath to aid the synchronization. In particular, we consider a class of serial search strategies and determine the optimal search procedure for the uncertainty space consisting of N[sub]s total cells and N[sub]Q correct cells. We derive closed-form expressions for both the minimum and maximum mean acquisition times (MATs) and the conditions for achieving these limits. We prove that the fixed-step serial search (FSSS), with the step size N[sub]Q, achieves the near-optimal MAT. We also prove that the conventional serial search, in which consecutive cells are tested sequentially, and the FSSS with the step size N[sub]s - 1 should be avoided as they result in the maximum MAT. Analytical tools used in the research include Markov chain diagrams, the transformation of feasible spaces, and convexity theory. Our results apply to all signal-to-noise ratio values, regardless of the detection-layer decision rule and the fading distribution. The impact of this research is significant for the design, implementation, and deployment of spread-spectrum systems.

This work serves as the first comprehensive investigation into typically developing children's acquisition of subject-to-subject (StS) raising. In particular, it asks how English-speaking children come to comprehend a StS raised sentence like (1) versus its semantically equivalent unraised counterpart (2), and how the presence of an experiencer-phrase affects interpretation (3): (1) John[subscript i] seems [t[subscript i] to be dancing]. (2) It seems that John is dancing. (3) John[subscript i] seems to Mary [t[subscript i] to be dancing]. The acquisition of StS raising is of particular bearing given renewed interest in the acquisition of verbal passives, which share syntactic traits with StS raising and which have been argued to develop late under genetic guidance. Using sentence-picture matching and truth-value judgment experiments, the following comprehension results obtain: e Unraised sentences are acquired early, with most three-year-old children demonstrating mastery. - Sentences involving StS raising over an experiencer (ROE) are delayed until around age seven, with many children incorrectly interpreting them as involving raising-to-object (RtO) syntax. e Sentences involving StS raising with no experiencer (RNE) are likewise delayed until around age seven, with many children incorrectly interpreting them as involving either subject control or copular syntax. - Subject control sentences are acquired early, by at least age three. - The delayed acquisition of StS raising (ROE and RNE) appears to be developmentally linked with the delayed acquisition of verbal passives. The noted delay in comprehension of StS raising occurs despite the fact that StS raising sentences are found to be relatively common in child-directed speech. These data serve to rule out several grammatical acquisition accounts in the literature that have attempted to capture children's delayed comprehension of verbal passives (e.g. External Argument Requirement Hypothesis, Canonical Alignment Hypothesis, and Universal Freezing Hypothesis). The data, however, are both compatible with and predicted by the Universal Phase Requirement (UPR; Wexler, 2004), a grammatical account on which children are claimed to take all vPs to define strong phases for maturational reasons. Only UPR correctly predicts delay for StS raising (with and without an experiencer-phrase) in early child grammar, and a positive correlation with the acquisition of verbal passives.

Economic agents often do not interact on the basis of some fixed prior information: choosing what to know is a central part of their interaction. The essays composing this thesis provide and apply theoretical tools to understand information as a choice variable. In the first essay on "Unrestricted Information Acquisition," I study costly information acquisition in games where players can acquire information not only about the state, but also about one another's information in a flexible way. Two main patterns emerges. First, in coordination games, players have a strong incentive to learn what others know: for instance, I show that this can explain the onset of phenomena such as bank runs or currency crises. Second, this incentive weakens as the game gets large and players small: for instance, I show that this leads nonfundamental volatility to vanish in many canonical large games. In the second essay on "Endogenous Informational Smallness," I deepen the investigation of unrestricted information acquisition in large games and show that players end up being informationally small in equilibrium. Information is valuable, but also costly: this is the tradeoff that makes information an economic good. Understanding the cost of information is challenging, since it usually reflects unobservable factors such as time, effort, and cognitive resources. In the third co-authored essay on "Rationally Inattentive Preferences," I highlight basic properties of the cost of information that can be assumed without loss of generality and are necessary and sufficient for identification from observable menu-choice data.

Abstract (sommario):
The cost of off-chip memory access (in bandwidth, time and energy consumption) has become a major concern in the design of many hardware systems. Due to reasons such as the increasing performance gap between computing engines and memory systems, the process of data acquisition from memory has an increasingly dominant impact to the overall of the system performance. The cost in memory communication bandwidth and time consumption of data acquisition has become more significant, stalling the application and reducing its execution. Energy consumption has also become one of the main concerns to modern hardware systems, especially for embedded applications, and the energy spent on memory accessing has been reported to occupy a large proportion of the overall energy consumption of the system. All these lead to the research topic of reducing the cost of memory access in hardware systems. Particularly for image processing systems, due to the ever growing size of image data, the task of image data acquisition poses an increasing challenge to the design of the systems. Various researches have addressed this problem of image data acquisition by exploiting the characteristics of memory structures and image processing applications. Some methods approach this problem from software perspective, changing for example the source code of the application so that the off-chip memory access is minimized; other methods approach this problem from hardware perspective, modifying the structure of memories and reorganizing the order of data transmission sequences. This thesis provides an alternative way of dealing with this problem and proposes the framework of ``Context-based Image Acquisition'' (CbIA) for hardware systems. Instead of accessing from the off-chip memory all image data requested by the application, the proposed framework accesses only fractions of the image and by utilizing image processing algorithms it reconstructs the missing part. This allows the proposed framework to trade computational effort for reduced cost of memory access, and ultimately trade image quality with reduced overall cost of the image acquisition process. On top of this, the proposed framework has the advantage of being independent from both the memory and the image processing application, and therefore can be seamlessly integrated into existing image processing systems. The thesis elaborates on the proposed framework from both the algorithmic perspective and the hardware architectural perspective. A designed and implemented CbIA architecture is evaluated on reconfigurable hardware, reporting a reduction of up to 88\% of communication bandwidth, 68\% of time consumption, and 50\% of energy consumption of the image acquisition process, at the expense of reduced image quality (about 33 dB of PSNR on chosen benchmark images). Based on this design, this thesis also investigates on more complex algorithms at simulation level for CbIA procedures, including that for generic images as well as for specific image class. The use of more detailed modelling of images and/or domain-specific knowledge improves the ability of the CbIA procedure to trade image quality for bandwidth reduction (an increase of about 2 dB of PSNR with the same bandwidth used), with additional expenses on the computational cost. Finally, the thesis explores the impact brought by the proposed CbIA framework to the future development of hardware system.

Telemetry & Instrumentation, in conjunction with NASA’s Kennedy Space Center, has developed a commercial, intelligent, data acquisition module that performs all functions associated with acquiring and digitizing a transducer measurement. These functions include transducer excitation, signal gain and anti-aliasing filtering, A/D conversion, linearization and digital filtering, and sample rate decimation. The functions are programmable and are set up from information stored in a local Transducer Electronic Data Sheet (TEDS). In addition, the module performs continuous self-calibration and self-test to maintain 0.01% accuracy over its entire operating temperature range for periods of one year without manual recalibration. The module operates in conjunction with a VME-based data acquisition system.

Gram-positive bacteria are characterized by a single lipid bilayer with a thick peptidoglycan layer. This group of organisms contains bacteria commonly associated with human infection, including: Staphylococcus aureus, Listeria monocytogenes, Bacillus anthracis and Streptococcus pneumoniae among others. These bacteria have a common system for importing iron in the form of heme, which is acquired by proteins containing heme-binding NEAT (NEAr iron Transporter) domains. The heme acquisition system in S. aureus is termed the Iron Surface Determinant (Isd) system and in L. monocytogenes is termed Heme Binding Protein (Hbp) and Heme/Hemoglobin Uptake Protein (Hup). These proteins work together to obtain heme from hemoglobin and then transport the heme into the cytoplasm via well characterized ABC-transporters. Although there have been clinical trials with antibodies directed against Isd proteins, there are currently no antibiotics targeting iron uptake systems in bacteria in general. Building upon fluorescent approaches for detection of iron uptake in Gram negative organisms, this work develops fluorescent heme acquisition detection in Gram positive organisms. The spectrofluorimetric methodology facilitates the understanding of heme acquisition protein interactions and mechanisms in bacteria. This work could subsequently be used to identify inhibitors of Gram positive bacterial iron uptake systems, and develop a new target for antibiotic action.

Abstract (sommario):
This dissertation contrasts two theories of language acquisition. The first theory (Universal Grammar Hypothesis - UGH), which has been dominant in generative linguistics, argues that acquisition is primarily mediated by innate properties of language provided by UG. The opposing view (General Pattern Learning Hypothesis - GPLH) is that language is acquired according to the patterns in the ambient language or input. These theories are contrasted by examining children's acquisition of coda consonants in CVC words. The UGH was based on the universally preferred codas. These data came from previous research and from frequency analyses of codas in CVC words from 35 languages. Results showed that languages prefer coronal codas and sonorant codas. These cross-linguistic preferences are interpreted as reflecting UG. Predictions of the GPLH were established through an examination of English codas in CVC words from a number of different sources. This examination revealed the frequency of codas in the input, upon which the GPLH was based. In order to determine which hypothesis better predicts children's coda acquisition, data were then collected from previously published research, from CHILDES, and from an experiment designed to test children's productions of English codas. To evaluate the UGH, children's coda productions were analysed to determine whether the preferred codas were coronals or sonorants. Results showed that neither of these codas were favoured. To evaluate the GPLH, analyses determined whether there were significant correlations between children's coda productions and the frequency of codas in English. Results showed that these relationships were significant. The role of the input was further examined in an experiment designed to test children's productions of the identical coda in non-words controlled for phonotactic probabilities. Results showed that phonotactic probabilities played a significant role in accounting for children's productions of the identical coda in different words. The results support an input-based account of phonological acquisition. Thus, language acquisition is best characterised with respect to patterns in the ambient language, where frequently occurring properties of the input serve to organise children's linguistic representations. The research here illustrates the importance of considering the input in children's acquisition of phonological structures.

Abstract (sommario):
In the last decade, the number of mergers and acquisitions (M&A) activities by emerging market firms has rapidly increased to exploit growing markets at home and abroad. In order to be successful in their M&A goals, these firms need to develop a specific M&A capability and manage post-M&A processes effectively. Drawing on the dynamic capabilities view, I develop a theoretical framework for emerging market acquirers that outlines the development of the acquisition capability mechanisms. I first examine the influence of prior acquisition experience on acquisition performance. I then go on to study the integration capability of emerging market firms and examine the effect of post-M&A integration strategies on the performance of acquisitions by emerging market firms. The overall results indicate that a firm‘s focal acquisition performance positively relates to prior acquisition experience that is similar to the focal acquisition. Moreover, post-M&A integration strategies vary depending on the geographical similarity of the focal acquisition. Replacing the target‘s top manager is a particularly important determinant of acquisition performance in domestic M&A. Finally, in this research, I also extend the organisational learning view and develop a multi-level analysis that examines the role of business groups alongside firm-level learning from acquisitions. The usual focus in emerging market studies is on the big emerging economies of Brazil, Russia, India and China (BRIC). I focus instead on the country case of Turkey, one of the second tier of ―biggish‖ growing economies of ―MIST‖ (Mexico, Indonesia, South Korea and Turkey). The empirical results are based on a unique hand-collected dataset of acquisitions in Turkey culled from publicly available data. The final dataset consists of 279 acquisitions between 1998 and 2011.

Abstract (sommario):

The accelerating globalisation has led to an increased number of acquisitions and mergers. This implies changes within the organisation and problems with the implementation process of the new organisation that is taken form. The integration of the companies involved makes it essential to identify and to be aware of the characteristics of different management cultures. Management culture is the way a company is managed influenced by the surrounding culture. Management culture is something that has often been developed since the origin and is permeating the company spirit. This dissertation focuses on the characteristics of American and Swedish management cultures. Ford acquired Volvo Cars in 1999 and in this study Ford is representing the American management culture whereas Volvo is representing the Swedish management culture. The two companies are considered to possess typical characteristics of the management cultures examined. The intention was to analyse how a company’s management culture is affected by an acquisition and if the possible effects are reflected outside the organisation. Examined theories were concentrated into the Management culture model containing five dimensions; Relations, Orientation, Decision-making, Motivation and Loyalty. Hypotheses were developed from the model and the perceptions of Volvo’s suppliers were evaluated through a survey. The results show conformity with the Management culture model, which indicates that Volvo has absorbed distinctive elements of Ford’s management culture. This might indicate that acquisitions between a bigger American company and a smaller Swedish company would imply consequences in the management culture.
