Magistro darbe "Frazeologizmai lietuvių prozos autorių tekstuose ir žodynuose" analizuojami 14 lietuvių autorių 35 – prozos, eseistikos, kritikos – tekstų, kuriuose užfiksuoti 1074 frazeologizmai (3005 jų pavartojimo atvejai). Šio darbo tikslas – nustatyti, kokie frazeologizmų tipai vyrauja lietuvių autorių tekstuose, aptarti jiems būdingus sisteminius požymius (polisemiją, sinonimiją, antonimiją, variantų įvairovę, dažnumą bei sudaromąją leksiką), tuo tikslu lyginant autorių vartojamus frazeologizmus su specializuotuose frazeologizmų žodynuose pateiktais duomenimis. Magistro darbe aptariama autorių frazeologizmų semantinė klasifikacija, jų funkcijos, analizuojami sintaksinės frazeologizmų sandaros tipai ir modeliai, apžvelgiama kilmė. Pateikiamose išvadose teigiama, kad frazeologizmai yra moderniosios prozos autorių kalbinės raiškos sudedamoji dalis, tačiau ji nesudaro specifinio grožinės literatūros frazeologijos posistemio. / Master of Art thesis deals with Phraseological units in Lithuanian prose authors’ texts and dictionaries. There have been analysed 35 prose, essayist, and critics texts written by 14 Lithuanian authors. In the texts, 1074 phraseological units have been found (3005 cases of their usage). This paper aims at identifying the types of phraseological units used in the texts by Lithuanian authors, discussing the most typical systematic features (polysemy, synonymy, antonymy, diversity of variants, frequency, and lexis). In order to achieve this aim, the phraseological units used by the authors have been compared with the data found in specialised phraseology dictionaries. In this paper, the semantic classification of phraseological units and their functions are described, the types and models of syntactic structures of phraseological units are analysed, and their origin is discussed. The conclusion shows that phraseological units are the part of language expression used by modern prose writers. However, this part does not compose a specific subsystem.

The concept of hyperreflexivity has previously been defined for subspaces of $B(X,Y)$, where $X$ and $Y$ are Banach spaces. We extend this concept to the subspaces of $B^n(X,Y)$, the space of bounded $n$-linear maps from $X\times\cdots\times X=X^{(n)}$ into $Y$, for any $n\in \mathbb{N}$. If $A$ is a Banach algebra and $X$ a Banach $A$-bimodule, we obtain sufficient conditions under which $\Zc^n(A,X)$, the space of all bounded $n$-cocycles from $A$ into $X$, is hyperreflexive. To do so, we define two notions related to a Banach algebra: The strong property $(\B)$ and bounded local units (b.l.u). We show that there are sufficiently many Banach algebras which have both properties. We will prove that all C$^*$-algebras and group algebras have the strong property $(\B).$ We also prove that finite CSL algebras and finite nest algebras have this property. We further show that for an arbitrary Banach algebra $A$ and each $n\geq 2$, $M_n(A)$ has the strong property $(\B)$ whenever it is equipped with a Banach algebra norm. In particular, this implies that all Banach algebras are embedded into a Banach algebra with the strong property $(\B)$. With regard to bounded local units, we show that all $C^*$-algebras and many group algebras have b.l.u. We investigate the hereditary properties of both notions to construct more example of Banach algebras with these properties. We apply our approach and show that the bounded $n$-cocycle spaces related to Banach algebras with the strong property $(\B)$ and b.l.u. are hyperreflexive provided that the space of the corresponding $n+1$-coboundaries are closed. This includes nuclear C$^*$-algebras, many group algebras, matrix spaces of certain Banach algebras and finite CSL and nest algebras. We finish the thesis with introducing {\it the hyperreflexivity constant}. We make our results more precise with finding an upper bound for the hyperreflexivity constant of the bounded $n$-cocycle spaces.

Patient satisfaction is an outcome of care that represents the patient's judgment on the quality of care. An important aspect of quality affecting patient's judgment can be attributed to patients' expectations and experiences regarding nursing care according to type of unit. The purpose of this study was to examine differences between patients' perceptions of satisfaction with nursing care in critical care units and medical units in one Midwestern hospital.The conceptual framework was "A Framework of Expectation" developed by Oberst in 1984, which asserted that patients have expectations of hospitals and health care professionals regarding satisfaction and dissatisfaction with care. The instrument used to measure patient satisfaction was Risser's Patient Satisfaction Scale, with three dimensions of patient satisfaction: (a) Technical-Professional, (b) Interpersonal-Educational, (c) Interpersonal-Trusting. The convenience sample included 99 patients50 from critical care units and 49 from medical wards. Participation was voluntary. The study design was comparative descriptive and data was analyzed using a t-test.The demographic data showed that the majority of patients had five or more admission. About one-third of the patients were 45-55, 56-65, 66-75, respectively. Findings related to the research questions were that: (a) 84 percent of the respondents rated overall satisfaction in the satisfactory to excellent range, (b) results of a t-test showed significant differences in overall patient satisfaction with patients being more satisfied with care in critical care units. Significant differences were found in three subscales with critical care being more satisfied. No relationship was found between patient satisfaction and age/and/or type of unit.Conclusions were that in both medical and critical care units patients were more satisfied with Technical-Professional and Interpersonal-Trusting than with Interpersonal-Educational. Also noted was that patients in the units where nurse-to-patient ratio was higher participants perceived that nurses had more time, energy and ability to meet patient expectation. Implications call for analysis of nurse/patient ratio in relation to patient satisfaction and nurses in relation to patient education as well as patient's perceptions of getting their needs met. / School of Nursing

The objectives of the study were to identify, classify, describe and map the plant communities in the proposed Highveld National Park, including the degraded Spitskop areas. Vegetation sampling was done by means of the Braun-Blanquet method and a total of 108 stratified random relevés were sampled. A numerical classification technique (TWINSPAN) was used and the result was refined by Braun-Blanquet procedures. The final results of the classification procedure were presented in the form of phytosociological tables and twelve plant communities were described. For indirect ordination, a Detrended Correspondence Analysis (DCA) algorithm was applied to the data set to confirm the phytosociological association and to assess floristic relations between communities. For direct environmental gradient analysis the Canonical Correspondence Analysis (CCA) was applied to the data using the CANOCO software program. The plant communities were combined into six management units based on similarities regarding vegetation composition, habitat, topography and soil characteristics. Characterization of land degradation was done by grouping erosion into different classes and different degrees of severity. Degraded areas in need of rehabilitation and restoration were identified and described. Recommendations were made with regard to rehabilitation and monitoring of all degraded areas in the HNP. / Thesis (M.Sc. (Botany))--North-West University, Potchefstroom Campus, 2008.

Graph traversal represents an important class of graph algorithms that is the nucleus of many large scale graph analytics applications. While improving the performance of such algorithms using GPUs has received attention, understanding and managing performance under power constraints has not yet received similar attention. This thesis first explores the power and performance characteristics of breadth first search (BFS) via measurements on a commodity GPU. We utilize this analysis to address the problem of minimizing execution time below a predefined power limit or power cap exposing key relationships between graph properties and power consumption. We modify the firmware on a commodity GPU to measure power usage and use the GPU as an experimental system to evaluate future architectural enhancements for the optimization of graph algorithms. Specifically, we propose and evaluate power management algorithms that scale i) the GPU frequency or ii) the number of active GPU compute units for a diverse set of real-world and synthetic graphs. Compared to scaling either frequency or compute units individually, our proposed schemes reduce execution time by an average of 18.64% by adjusting the configuration based on the inter- and intra-graph characteristics.

As the further development of single-core architectures faces seemingly insurmountable physical and technological limitations, computer designers have turned their attention to alternative approaches. One such promising alternative is the use of several smaller cores working in unison as a programmable hardware accelerator. It is clear that the vast – and, as yet, largely untapped – potential of hardware accelerators is coming to the forefront of computer architecture. There are many challenges that must be addressed for the programmable hardware accelerator to be realized in practice. In this thesis, load-balancing, on-chip communication, and an execution model are studied. Imbalanced distribution of workloads across the processing elements constitutes wasteful use of resources, which results in degrading the performance of the system. In this thesis, a hardware-based load-balancing technique is proposed, which is demonstrated to be more scalable than state-of-the-art loadbalancing techniques. To facilitate efficient communication among ever increasing number of cores, a scalable communication network is imperative. Packet switching networks-on-chip (NoC) is considered as a viable candidate for scalable communication fabric. The size of flit, which is a unit of flow control in NoC, is one of important design parameters that determine latency, throughput and cost of NoC routers. How to determine an optimal flit size is studied in this thesis and a novel router architecture is proposed, which overcomes a problem related with the flit size. This thesis also includes a new execution model and its supporting architecture. An event-driven model that is an extension of hardware description language is employed as an execution model. The dynamic scheduling and module-level prefetching for supporting the event-driven execution model are evaluated.

The demand for heterogeneous computing, because of its performance and energy efficiency, has made on-chip heterogeneous chip multi-processors (HCMP) become the mainstream computing platform, as the recent trend shows in a wide spectrum of platforms from smartphone application processors to desktop and low-end server processors. The performance of on-chip GPUs is not yet comparable to that of discrete GPU cards, but vendors have integrated more powerful GPUs and this trend will continue in upcoming processors. In this architecture, several system resources are shared between CPUs and GPUs. The sharing of system resources enables easier and cheaper data transfer between CPUs and GPUs, but it also causes resource contention problems between cores. The resource sharing problem has existed since the homogeneous (CPU-only) chip-multi processor (CMP) was introduced. However, resource sharing in HCMPs shows different aspects because of the different nature of CPU and GPU cores. In order to solve the resource sharing problem in HCMPs, we consider efficient shared resource management schemes, in particular tackling the problem in shared last-level cache and interconnection network. In the thesis, we propose four resource sharing mechanisms: First, we propose an efficient cache sharing mechanism that exploits the different characteristics of CPU and GPU cores to effectively share cache space between them. Second, adaptive virtual channel partitioning for on-chip interconnection network is proposed to isolate inter-application interference. By partitioning virtual channels to CPUs and GPUs, we can prevent the interference problem while guaranteeing quality-of-service (QoS) for both cores. Third, we propose a dynamic frequency controlling mechanism to efficiently share system resources. When both cores are active, the degree of resource contention as well as the system throughput will be affected by the operating frequency of CPUs and GPUs. The proposed mechanism tries to find optimal operating frequencies for both cores, which reduces the resource contention while improving system throughput. Finally, we propose a second cache sharing mechanism that exploits GPU-semantic information. The programming and execution models of GPUs are more strict and easier than those of CPUs. Also, programmers are asked to provide more information to the hardware. By exploiting these characteristics, GPUs can energy-efficiently exercise the cache and simpler, but more efficient cache partitioning can be enabled for HCMPs.

Intensive care units (ICUs) emerged across Canada during the early 1960s, significantly contributing to the image of Western hospitals as places of scientific advancement that predominated over much of the twentieth century. ICUs rapidly became both a resource intensive and expensive type of care as the number and size of units increased to accommodate diverse patient populations and treatment options. Nurses enabled the formation and growth of ICUs through their constant presence and skilled care. There has been limited research, however, regarding the historical development of Canadian ICUs, the relationships between nurses and other personnel in such units, how they developed an identity as ICU nurses, or how ICU nursing became a specialty practice. Situated within the broader histories of hospitals, healthcare, and nursing, this study uses a social history approach to examine nurses’ experiences within Canadian ICUs between 1960 and 2002. Berger and Luckmann’s Social Construction of Reality provided a lens for analysis and interpretation of oral histories, photographs, professional literature of the time period under study, and both archival and organizational records. This thesis argues that ICU nurses’ relationships with one another, in the context of a technologically complex environment, socially constructed their knowledge and skill acquisition, their socialization as ICU nurses, and the development of a specialized body of knowledge that ultimately led to formal recognition of ICU nursing as a specialty in Canada.

Research indicates that large numbers of young people are underachieving in UK schools, and that school exclusion levels are unacceptably high. In addition, there are increased numbers of students unable to secure a place in mainstream schools. These unplaced and excluded young people are described by New Labour as `vulnerable', `disaffected' or at risk of disaffection (Social_Exclusion_Unit 1998b). The numbers of young people considered `disaffected' indicates a national problem and so, in response to this, there is a government led drive to `socially include' `excluded' young people and young people considered `at risk' of `exclusion'. This UK study examines the principles and practices of practitioners working with identified `at-risk' and `hard to reach' populations. This thesis seeks to unpack this complex situation of social `exclusion' and `inclusion' as it relates to education by asking; who are the `actors' in this expanding world of `social inclusion'? How can some practitioners `reach' and `include' so called `hard to reach' `disaffected' young people? This research explores socially inclusive practice. It aims to investigate whether a model of socially inclusive practice exists or can be established that could be used by educators, parents, human resource (HR) professionals and others concerned with client services in the helping professions. Social exclusion is one of the key concerns of the New Labour agenda. Inclusive education is perceived as central to promoting social inclusion (Social_Exclusion_Unit 1998b) and as a result there are a number of social inclusion projects operating throughout the UK. These projects generally offer provision for young people who, in the judgement of excluding mainstream practitioners, should be placed outside of their responsibility. These excluding practices reflect the values and ideal of the institution and how they perceive their own ability to respond to the total needs of the learner in their care. Excluded young people are typically referred to pupil referral units (PRU's), study centres or other education provision established to meet the statutory requirement of the education authority to maintain education provision. The practitioner is the focus of this investigation and preliminary issues associated with an investigation into social inclusion practice will be considered in an attempt to identify `what works' in opening up educational opportunities to an inclusive culture. This study then, examines the practice and rationale employed by staff at a project providing education otherwise than at school (EOTAS) to young people unplaced, excluded or at risk of exclusion from mainstream school by analysing empirical data collected over a 3-year period using qualitative instruments. Grounded Theory is the methodological approach used to elicit data and the findings provide valuable insights into inclusive education practices. In addition, a number of relevant and important issues are identified. The theoretical model that emerges is informed by the insights and issues that emerge in this, the first major UK study, into inclusive practice in education where the practitioner is the main focus of the study. This research puts forward a model of professional understanding for inclusive education and makes a contribution to the development of new approaches. The results offer clear indicators for a transferable framework of socially inclusive practice.

The goal of this research is to disclose constitutional elements of local governance. In reference to the second tier – county, the Lithuanian constitution stipulates that the government according to procedures established by law organizes higher level administrative units. The point of analysis is Lithuanian local government concept and system, territorial administrative reforms, relationship between local self-government and the second tier of the state government. The same point of view is used to review and compare Lithuanian and Slovenian territorial administrative organization, implemented in both constitutions. The study although provides analysis of Lithuanian county policy, its formation and implementation prior restoration of independence.
