En la actualidad, las empresas basan su gestión en la utilización de la información, por lo cual necesitan el apoyo de los recursos tecnológicos para facilitar esta labor, sin importar la razón social o el sector productivo al que pertenezcan. Es por ello, que las Tecnologías de la Información juegan un papel muy importante para la toma de decisiones, brindando en el menor tiempo posible información organizada. Sin embargo, en muchas ocasiones por responder a necesidades internas o externas de manera precipitada, se adquieren tecnologías de información sin un adecuado proceso de análisis organizativo y establecimiento de requerimientos, lo que implica en algunos casos una errada selección de los proveedores o una adquisición de tecnología equivocada. Este modelo se fundamenta en unos referentes normativos tanto internos como externos, así como en unos componentes teóricos, asociados a cada una de las fases que lleva éste y que servirán para la comprensión del mismo. Además, el Modelo de Gestión para la Adquisición de Tecnologías de Información, servirá como base para llevar a cabo de forma organizada el proceso a seguir en la contratación de un servicio o producto en materia de Tecnologías de la Información.

Independent India continued with the land acquisition policy based on the doctrine of eminent domain.In the early two and three decades after independence, land acquisition has not been a major challenge Rights were limited, political and non-political organizations mobilizing the public against such acquisitions made them aware of the different provisions of the Land Acquisition Act. However, this situation has gradually changed and land acquisition for infrastructure and developmental works has become difficult. At places like Singer in West Bengal the government was forced to stop the land acquisition and have finally returned the land to the original owners based on court directions. Courts that have generally limited themselves to compensate for property acquired in the interest of society rather than the welfare of an individual have gradually begun to see land acquisition from different perspectives. Even after repeal of the colonial land acquisition act of 1894 and enactment of the new citizen friendly land acquisition act in 2013, the government continues to face major challenges in acquiring lands. At the same time there have been some initiatives in employing alternative land acquisition models and employing them successfully. This study traces the process of land acquisition in India and makes case studies of a few alternative land acquisition models and their reception by the people.

Aim/Purpose: Acquisitions play a pivotal role in the growth strategy of a firm. Extensive resources and time are dedicated by a firm toward the identification of prospective acquisition candidates. The Indian manufacturing sector is currently experiencing significant growth, organically and inorganically, through acquisitions. The principal aim of this study is to explore models that can predict acquisitions and compare their performance in the Indian manufacturing sector. Background: Mergers and Acquisitions (M&A) have been integral to a firm’s growth strategy. Over the years, academic research has investigated multiple models for predicting acquisitions. In the context of the Indian manufacturing industry, the research is limited to prediction models. This research paper explores three models, namely Logistic Regression, Decision Tree, and Multilayer Perceptron, to predict acquisitions. Methodology: The methodology includes defining the accounting variables to be used in the model which have been selected based on strong theoretical foundations. The Indian manufacturing industry was selected as the focus, specifically, data for firms listed in the Bombay Stock Exchange (BSE) between 2010 and 2022 from the Prowess database. There were multiple techniques, such as data transformation and data scrubbing, that were used to mitigate bias and enhance the data reliability. The dataset was split into 70% training and 30% test data. The performance of the three models was compared using standard metrics. Contribution: The research contributes to the existing body of knowledge in multiple dimensions. First, a prediction model customized to the Indian manufacturing sector has been developed. Second, there are accounting variables identified specific to the Indian manufacturing sector. Third, the paper contributes to prediction modeling in the Indian manufacturing sector where there is limited research. Findings: The study found significant supporting evidence for four of the proposed hypotheses indicating that accounting variables can be used to predict acquisitions. It has been ascertained that statistically significant variables influence acquisition likelihood: Quick Ratio, Equity Turnover, Pretax Margin, and Total Sales. These variables are intrinsically linked with the theories of liquidity, growth-resource mismatch, profitability, and firm size. Furthermore, comparing performance metrics reveals that the Decision Tree model exhibits the highest accuracy rate of 62.3%, specificity rate of 66.4%, and the lowest false positive ratio of 33.6%. In contrast, the Multilayer Perceptron model exhibits the highest precision rate of 61.4% and recall rate of 64.3%. Recommendations for Practitioners: The study findings can help practitioners build custom prediction models for their firms. The model can be developed as a live reference model, which is continually updated based on a firm’s results. In addition, there is an opportunity for industry practitioners to establish a benchmark score that provides a reference for acquisitions. Recommendation for Researchers: Researchers can expand the scope of research by including additional classification modeling techniques. The data quality can be enhanced by cross-validation with other databases. Textual commentary about the target firms, including management and analyst quotes, provides additional insight that can enhance the predictive power of the models. Impact on Society: The research provides insights into leveraging emerging technologies to predict acquisitions. The theoretical basis and modeling attributes provide a foundation that can be further expanded to suit specific industries and firms. Future Research: There are opportunities to expand the scope of research in various dimensions by comparing acquisition prediction models across industries and cross-border and domestic acquisitions. Additionally, it is plausible to explore further research by incorporating non-financial data, such as management commentary, to augment the acquisition prediction model.

The photogrammetric acquisition of 3D object models can be achieved by Structure from Motion (SfM) computation of photographs taken from multiple viewpoints. All-around 3D models of small artefacts with complex geometry can be difficult to acquire photogrammetrically and the precision of the acquired models can be diminished by the generic application of automated photogrammetric workflows. In this paper, we present two versions of a complete rotary photogrammetric system and an automated workflow for all-around, precise, reliable and low-cost acquisitions of large numbers of small artefacts, together with consideration of the visual quality of the model textures. The acquisition systems comprise a turntable and (i) a computer and digital camera or (ii) a smartphone designed to be ultra-low cost (less than $150). Experimental results are presented which demonstrate an acquisition precision of less than 40 μ m using a 12.2 Megapixel digital camera and less than 80 μ m using an 8 Megapixel smartphone. The novel contribution of this work centres on the design of an automated solution that achieves high-precision, photographically textured 3D acquisitions at a fraction of the cost of currently available systems. This could significantly benefit the digitisation efforts of collectors, curators and archaeologists as well as the wider population.

Purpose Academic libraries continue to invest in eBooks to ensure access to content in various formats. This paper aims to examine eBook acquisition models, including patron-driven acquisitions, one-time purchases, focused collection subscriptions or large-scale subscriptions, to better understand how users engage with this content based on usage data. Design/methodology/approach Usage data provide insights into eBook acquisition and how access models influence use. This study defines the acquisition model for each eBook purchase. Data were examined to determine usage by acquisition model and cost-per-use. Findings This paper finds that for a large suburban community college, a large-scale subscription model has the lowest cost-per-use and serves the largest portion of students. Focused collection subscriptions supported small, specialized programs in the Allied Health, Emergency Services, and Nursing fields. Originality/value This paper examines how eBooks are acquired to determine which model best serves an academic library community, specifically a community college library, which is currently underrepresented in the literature.

Merger and acquisition (M&A) transactions are often associated with increasing market share, improved operational efficiency and the ability to create value. Nevertheless, many studies have presented the drawbacks of M&A transactions, including an increase in the risk of bankruptcy. A significant number of companies go bankrupt in Hungary every year, even in non-recession periods. The goal of our analysis is to examine how the risks of companies, especially their bankruptcy risks, were affected by acquisitions in Hungary between 2008 and 2017. The results of our study with a focus on Hungarian companies confirm the research published in the international literature, according to which M&A transactions are unsuccessful in many cases, and the transactions are often followed by adverse effects. Our research results may change the perspectives associated with the allegedly well-known benefits and expectations of acquisitions. Based on our research, we recommend that companies planning to merge or acquire should also consider the possible failure of such transactions.

SUMMARYIntroduction: The nursing professional is a participant in social, economic and cultural changes at present; as well as the well-being of people in terms of health. This activity involves the training of professionals in care for the diagnosis and treatment of diseases, through knowledge and study in this field. To do this, it must establish a proposal for awareness, prevention, and intervention in individual and collective health problems, characterized by a humanist position where critical thinking models the new challenges in quality management of health services and medical care. Objective: The objective is the theoretical analysis of critical thinking in nursing, through the review of literature with expression of this concept Materials and methods: It consists of a study with a qualitative-descriptive approach, with an analysis of the information related to the descriptors under study. Results: The challenges facing nursing in the 21st century are demanding due to historical, political, demographic, cultural, economic and technological events. And it is the transformative vision of critical thinking that manages the strengthening of the development of skills and abilities of nurses for the provision of health services and medical care. Conclusions: Critical thinking is a valuable tool for the training of nursing professionals, since it models the change of thought and theoretical practical actions, for the acquisition of new knowledge and quality management in health services and medical care. Despite the advances in health science, critical thinking shows low levels in terms of the education and training of these professionals

Abstract. Small satellites play an increasing role in earth observation. This article evaluates different possibilities of utilizing data from Planet’s SkySat and PlanetScope satellites constellations for derivation of digital elevation models. While SkySat provides high resolution image data with a ground sampling distance of up to 50 cm, the PlanetScope constellation consisting of Dove 3U cubesats provide images with a resolution of around 4 m. The PlanetScope acquisition strategy was not designed for stereo acquisitions, but for daily acquisition of nadir viewing imagery. Multiple different products can be acquired by the SkySat satellites: Collects covering an area of usually 12 by 6 km, tri-stereo collects and video products with a framerate of 30 Hz. This study evaluates DSM generation using a Semi-Global Matching from multi date stereo pairs for SkySat and PlanetScope, and the dedicated Video and tri-stereo SkySat acquisitions. DSMs obtained by merging many PlanetScope across track stereo pairs show an normalized median deviation against LiDaR first pulse data of 5.2 meter over diverse landcover at the test sites around the city of Terrassa in Catalonia, Spain. SkySat tri-stereo products with 80 cm resolution reach an NMAD of 1.3 m over Terrassa.

Background Complex transmission models of healthcare-associated infections provide insight for hospital epidemiology and infection control efforts, but they are difficult to implement and come at high computational costs. Structuring more simplified models to incorporate the heterogeneity of the intensive care unit (ICU) patient-provider interactions, we explore how methicillin-resistant Staphylococcus aureus (MRSA) dynamics and acquisitions may be better represented and approximated. Methods Using a stochastic compartmental model of an 18-bed ICU, we compared the rates of MRSA acquisition across three ICU population interaction structures: a model with nurses and physicians as a single staff type (SST), a model with separate staff types for nurses and physicians (Nurse-MD model), and a Metapopulation model where each nurse was assigned a group of patients. The proportion of time spent with the assigned patient group (γ) within the Metapopulation model was also varied. Results The SST, Nurse-MD, and Metapopulation models had a mean of 40.6, 32.2 and 19.6 annual MRSA acquisitions respectively. All models were sensitive to the same parameters in the same direction, although the Metapopulation model was less sensitive. The number of acquisitions varied non-linearly by values of γ, with values below 0.40 resembling the Nurse-MD model, while values above that converged toward the Metapopulation structure. Discussion Inclusion of complex population interactions within a modeled hospital ICU has considerable impact on model results, with the SST model having more than double the acquisition rate of the more structured metapopulation model. While the direction of parameter sensitivity remained the same, the magnitude of these differences varied, producing different colonization rates across relatively similar populations. The non-linearity of the model’s response to differing values of a parameter gamma (γ) suggests simple model approximations are appropriate in only a narrow space of relatively dispersed nursing assignments. Conclusion Simplifying assumptions around how a hospital population is modeled, especially assuming random mixing, may overestimate infection rates and the impact of interventions. In many, if not most, cases more complex models that represent population mixing with higher granularity are justified.

In this study, first results of retrieving plant heights of maize fields from multitemporal TanDEM-X images are shown. Three TanDEM-X dual polarization spotlight acquisitions were taken over a rural area in Germany in the growing season 2014. By interferometric processing, digital terrain models (DTM) were derived for each date with 5m resolution. From the data of the first acquisition (June 1st) taken before planting, a DTM of the bare ground is generated. The data of the following acquisition dates (July 15th, July 26th) are used to establish crop surface models (CSM). A CSM represents the crop surface of a whole field in a high resolution. By subtracting the DTM of the ground from each CSM, the actual plant height is calculated. Within these data sets 30 maize fields in the area of interest could be detected and verified by external land use data. Besides the spaceborne measurements, one of the maize fields was intensively investigated using terrestrial laser scanning (TLS), which was carried out at the same dates as the predicted TanDEM-X acquisitions. Visual inspection of the derived plant heights, and accordance of the individually processed polarisations over the maize fields, demonstrate the feasibility of the proposed method. Unfortunately, the infield variability of the intensively monitored field could not be successfully captured in the TanDEM-X derived plant heights and merely the general trend is visible. Nevertheless, the study shows the potential of the TanDEM-X constellation for maize height monitoring on field level.

Cette these a pour objet d'etablir le role respectif de differents parametres dans un modele de l'acquisition de quelques prepositions par l'enfant francophone de 2 a 10, 11 ans : a, de, dans, pres de, sur et entre. D'une part, elle se propose de tester la validite d'une dichotomie des prepositions selon leur valeur (spatiale ou casuelle). D'autre part, elle tente de determiner quel modele d'acquisition (perceptivo-semantique et ou cognitif) est le plus pertinent pour expliquer la maitrise de ces elements. Apres un resume des theories proposees sur la preposition et sur l'apprentissage, elle presente un protocole en quatre taches : deux epreuves de comprehension et deux de production. Les resultats montrent que la valeur spatiale ou casuelle des prepositions n'est pas un facteur facilitant l'apprentissage bien qu'il semble que les enfants en aient une certaine conscience tres tot. La maitrise des prepositions se fait d'abord en comprehension avant de se faire en expression. Cependant, en comprehension, les resultats ne nous premettent pas de nous prononcer de maniere categorique en faveur de l'un ou l'autre des modeles. Par contre, en expression, les choses paraissent plus claires : un modele fonde sur le developpement cognitif parait pertinent pour expliquer la maniere dont les enfants maitrisent ces elements. En effet, ils commencent par exprimer les prepositions "pres de" et "dans" faisant appel a des notions d'espace topologique (entourage, voisinage. . . ). Avec l'apparition de la droite projective vers 6 ans, apparaissent les prepositions faisant intervenir l'espace projectif. En conclusion, il est fort possible que la "verite" se trouve dans un modele "mixte", integrant des faits semantico-perceptifs et des concepts cognitifs, sans oublier la part des strategies utilisees
The aim of this thesis is to study different components in the acquisition of prepositions among french-speaking children aged from 2 to 10. 11 : a, de, dans, pres de, sur, entre. First, it assesses the redevance of a dichotomy between prepositions : spatial or casual. Second, it tries to define wich model (sementically-perceptive and or cognitive) is the best to explain this acquisition. After a synthetic presentation of theories on preposition acquisition, it offers an investigation with 4 tasks (2 production and 2 comprehension). Results show that the dichotomy is not pertinent ot explain acquisition although young children seem to have a certain "conscience" of it. Acquisition begins by comprehension ; but the results of this part don't permit to determine wich model is the more adapted. On the other hand, in production, we can assume that a model based on cognitive development is pertinent. Children begin to produce prepositions ("pres de", "dans") involving topologic space (encirclement, proximity. . . ). With projective right's apparition, at 6, they produce prepositions involving pronective space. To conclude, it's likely that the "thruth" is a mixed model including semanticallyperceptive facts, cognitive notions togother with strategies used by choldren

This work investigates a computational model of first language acquisition; the Categorical Grammar Learner or CGL. The model builds on the work of Villavicenio, who created a parametric Categorical Grammar learner that organises its parameters into an inheritance hierarchy, and also on the work of Buszkowski and Kanazawa, who demonstrated the learnability of a k-valued Classic Categorial Grammar (which uses only the rules of function application) from strings. The CGL is able to learn a k-valued General Categorial Grammar (which uses the rules of function application, function composition and Generalised Weak Permutation). The novel concept of Sentence Objects (simple strings, augmented strings, unlabelled structures and functor-argument structures) are presented as potential points from which learning may commence. Augmented strings (which are stings augmented with some basic syntactic information) are suggested as a sensible input to the CGL as they are cognitively plausible objects and have greater information content than strings alone. Building on the work of Siskind, a method for constructing augmented strings from unordered logic forms is detailed and it is suggested that augmented strings are simply a representation of the constraints placed on the space of possible parses due to a sting’s associated semantic content. The CGL make crucial use of a statistical Memory Module (constructed from a type memory and Word Order Memory) that is used to both constrain hypotheses and handle data which is noisy or parametrically ambiguous. A consequence of the Memory Module is that the CGL learns in an incremental fashion. This echoes real child learning as documented in Brown’s Stages of Language Development and also as alluded to by an included corpus study of child speech. Furthermore, the CGL learns faster when initially presented with simpler linguistic data; a further corpus study of child-directed speech suggests that this echoes the input provided to children. The CGL is demonstrated to learn from real data. It is evaluated against previous parametric learners (the Triggering Learning Algorithm of Gibson and Wexler and the Structural Triggers Learner of Fodor and Sakas) and is found to be more efficient.

Discovering a word’s part of speech is an essential step in acquiring the grammar of a language. In this thesis we examine a variety of computational Bayesian models that use linguistic input available to children, in the form of transcribed child directed speech, to learn part of speech categories. Part of speech categories are characterised by contextual (distributional/syntactic) and word-internal (morphological) similarity. In this thesis, we assume language learners will be aware of these types of cues, and investigate exactly how they can make use of them. Firstly, we enrich the context of a standard model (the Bayesian Hidden Markov Model) by adding sentence type to the wider distributional context.We show that children are exposed to a much more diverse set of sentence types than evident in standard corpora used for NLP tasks, and previous work suggests that they are aware of the differences between sentence type as signalled by prosody and pragmatics. Sentence type affects local context distributions, and as such can be informative when relying on local context for categorisation. Adding sentence types to the model improves performance, depending on how it is integrated into our models. We discuss how to incorporate novel features into the model structure we use in a flexible manner, and present a second model type that learns to use sentence type as a distinguishing cue only when it is informative. Secondly, we add a model of morphological segmentation to the part of speech categorisation model, in order to model joint learning of syntactic categories and morphology. These two tasks are closely linked: categorising words into syntactic categories is aided by morphological information, and finding morphological patterns in words is aided by knowing the syntactic categories of those words. In our joint model, we find improved performance vis-a-vis single-task baselines, but the nature of the improvement depends on the morphological typology of the language being modelled. This is the first token-based joint model of unsupervised morphology and part of speech category learning of which we are aware.

Annotation:

Most of the current research in L2 vocabulary acquisition has been too focused on what it is to learn a word, and has neglected how whole vocabularies grow or decline. In general, it is assumed that vocabulary gains and losses are incremental and follow a linear progression. This thesis postulates a model which considers several discrete stages of knowledge and accounts for the unstable nature of vocabulary knowledge, where words can change from one state to any other. Matrix algebra is a tool capable to operate with such a model and produce long-term forecasts of vocabulary size. Our experimental work describes the retention and the overall growth of the vocabulary of advanced learners of Spanish. These experiments show that forecasts of vocabulary size generated by the matrix model are far more accurate than those generated by a linear model. With data from two self-rating tasks containing a large number of words completed within a given lapse we build matrices which generate forecasts of vocabulary knowledge. These forecasts highly correlate to the actual knowledge measured three and four months later. This methodology is tested with subjects of various groups, using words from different frequency bands, and different measurement scales. In addition, we indicate ways of identifying matrices likely to generate inaccurate predictions. This methodology is considered one step forward towards the establishment of a model for L2 vocabulary acquisition.

This thesis develops a range of prediction models for the purpose of predicting the acquisition of commercial banks in the European Union using publicly available data. Over the last thirty years, there have been approximately 30 studies that have attempted to identify potential acquisition targets, all of them focusing on non-bank sectors. We consider that prediction models developed specifically for the banking industry are essential due to the unusual structure of banks' financial statements, differences in the environment in which banks operate and other specific characteristics of banks that in general distinguish them from non-financial firms. We focus specifically on the EU banking sector, where M&As activity has been considerable in recent years, yet academic research relating to the EU has been rather limited compared to the case of the US. The methodology for developing prediction models involved identifying past cases of acquired banks and combining these with non-acquired banks in order to evaluate the prediction accuracy of various quantitative classification techniques. In this study, we construct a base sample of commercial banks covering 15 EU countries, and financial variables measuring capital strength, profit and cost efficiency, liquidity, growth, size and market power, with data in both raw and country-adjusted (i.e. raw variables divided by the average of the banking sector for the corresponding country) form. In order to allow for a proper comparative evaluation of classification methods, we select common subsets of the base sample and variables with high discriminatory power, dividing the sample period (1998-2002) into training sub-sample for model development (1998-2000), and holdout sub-sample for model evaluation (2001-2002). Although the results tend to support the findings of studies on non-financial firms, highlighting the difficulties in predicting acquisition targets, the prediction models we develop show classification accuracies generally higher than chance assignment based on prior probabilities. We also consider the use of equal and unequal matched holdout samples for evaluation, and find that overall classification accuracy tends to increase in the unequal matched samples, implying that equal matched samples do not necessarily overstate the prediction ability of models. The main goal of this study has been to compare and evaluate a variety of classification methods including statistical, econometric, machine learning and operational research techniques, as well as integrated techniques combining the predictions of individual classification methods. We found that some methods achieved very high accuracies in classifying non-acquired banks, but at the cost of relatively poor accuracy performance in classifying acquired banks. This suggests a trade-off in achieving high classification accuracy, although some methods (e.g. Discriminant) performed reasonably well in terms of achieving balanced overall classification accuracies of above chance predictions. Integrated prediction models offer the advantage of counterbalancing relatively poor performance of some classification methods with good performance of others, but in doing so could not out-perform all individual classification methods considered. In general, we found that the outcome of which method performed best depended largely on the group classification accuracy considered, as well as to some extent on the choice of the discriminatory variables. Concerning the use of raw or country-adjusted data, we found no clear effect on the prediction ability of the classification methods.

Annotation:

Water vapor sorption is a fundamental characteristic of wood as a building material. Apart from empirical prediction, models are often used to interpret the time-dependent process of water vapor uptake (sorption kinetics) and equilibrium states of water in wood (sorption isotherms). This paper summarizes our recent investigations into measurement methods and popular models that are widely used for interpreting these physical phenomena. Commonly used criteria for determining equilibrium moisture content with the dynamic vapor sorption technique yield much larger errors than previously thought. A more rigorous equilibrium criterion and a method to reduce data acquisition time are proposed. Evaluation of the parallel exponential kinetics model with improved data and multi-exponential decay analysis indicates that this model is unable to characterize the full sorption kinetic response following a step change in relative humidity. Fitting of common sorption isotherm models to high-quality equilibrium data for wood gives model predicted physical quantities such as monolayer capacity and enthalpy of sorption that are far from agreement with independently measured data. Thus, these models are not valid for water vapor sorption in wood. New theoretical models are needed that correctly describe the physical phenomena.
