‘Acting Out’ and ‘Working Through’ Departure in Thomas Pynchon’s Bleeding Edge
Authors: Fernandez Santiago Miriam
Published: November 2020

The present article explores the literary means by which Pynchon’ Bleeding Edge (2013) approaches post-traumatic reactions to 9/11 at the personal and public levels. The posttraumatic reactions that LaCapra has defined as “acting out” and “working through” are explored in their aesthetic and ethical dimensions, mainly through the study of Pynchon’s construction of narrative anticipation and his use of the elegiac tradition. I conclude that the novel might suggest a realignment of postmodern predicaments in reconciliation with the modernist tradition as a means to work through social and aesthetic trauma. I also contend that Pynchon problematizes his typical luddite approach to the posthuman by means of an allegorical use of communication technologies as a site for ritual mourning.
A Qualitative Analysis of Fahrenheit 451°: Mapping the Linguistic Make-Up of Literary Texts
Authors: Gorlach Marina
Published: November 2020

This paper presents a qualitative analysis of a literary text, Ray Bradbury’s (1953, 1964) Fahrenheit 451°, by considering the role of word systems in conveying its message. The word system is a matrix of words within a spoken or written text with a common denominator that may be semantic, phonological, etymological, conceptual, or associative. The analysis is based on a semiotic theoretical and methodological approach and focuses on the non-arbitrary choice of lexical/phonological/syntactic/semantic forms by the author as a means of achieving textual cohesion. Bradbury’s Fahrenheit 451° is a lyrical anti-utopia portraying the massive attack of ‘consumer civilization’ standards on the traditional cultural values of society. The message is conveyed via an array of word systems: the phonological system based on the alliteration of [s] creating the impression of burning paper, the conceptual-associative field ‘dark-cold-empty’, the metaphoric-metonymic systems ‘hands and body parts’ and ‘show-carnival’, the use of internal dialogue and monologue, and such syntactic strategies as elliptical sentences, tag-questions, and more. The findings of this study obtained through a qualitative analysis show how the effect of Bradbury’s work is created by the author’s sophisticated use of multiple word systems at all levels of language structure.
Response to Anna Kristina Hultgren’s Global English: From “Tyrannosaurus Rex” to “Red Herring”
Authors: Block David
Published: November 2020

In this response to Anna Kristina Hultgren’s paper, ‘Global English: From “Tyrannosaurus Rex” to “Red Herring”’, I begin by aligning myself with the general thrust of Hultgren’s argument, namely that if Applied Linguists really want to help combat social injustice in the world, they will have to abandon the notion that language must be at the centre of all social analysis, realising that this focus is never going to be enough to ensure the achievement of their goal. In addition, they will need to engage with Marxist political economy in greater depth than they perhaps have done in the past. I then devote some space to clarifications of key terminology such as political economy, materialism and class, before moving back to the key idea I mean to convey, namely that a focus on language is not going to make much of a contribution to making world a better place when the real problem is the ongoing march of capitalism and the increasing inequality and the damage to the environment that it engenders.
Language and Social Justice: Using Language as a Lens for Investigating Inequalities
Authors: Lønsmann Dorte
Published: November 2020

This article argues that if we as applied linguists are interested in social justice, we need to look at language with the aim of uncovering underlying social injustices. We can do this by investigating how language practices, language policies and language ideologies are tied up with social and material inequalities. The two cases discussed in the article focus on the role of English as a global language in the context of international business. By critically examining how language practices, language policies and language ideologies are tied up with underlying ideologies of globalism and neoliberalism, we can see how English in the business world is commodified as a communicative resource important for its potential economic value, but also how this commodification and the neoliberal ideology of employability mean that workers are the ones who bear the cost of internationalisation. Taking a critical perspective on global English means that investigating language does not have to be a misdirection away from the real issues of social injustice and inequality. Instead we as applied linguists can use language as a lens for investigating social injustice.

Who Profits From Global English? Reply to Hultgren
Authors: Haberland Hartmut
Published: November 2020

In my reply to Hultgren, I suggest introducing further aspects into the discussion of ‘global English’, like the question not only of ownership of a language but also of ownership and control of the communication channels, the problematic status of metaphors like ‘market’, the connection between global English and the narrowing of the base of available knowledge, the importance of a shared language, and the relevance of the ideology of globalism for discourses of global English.
Who’s Afraid of Multilingualism? Language and Intersectionality
Authors: Brutt-Griffler Janina
Published: November 2020

This contribution to the special issue addresses questions of social justice in the field of applied linguistics through the optics of multilingualism and intersectionality and from the standpoint of language teachers and learners. In monolingualist ideology, the multilingual speaker is transformed from the normal condition to the linguistic other, especially those without a clearly identifiable L1 or whose L1 does not conform to their presupposed linguistic identity. Linguistic theory contributes to this result by assigning an almost mystic quality to the “mother tongue” and its “native speakers,” when these questions can be and are quite fluid in our multilingual world. This article suggests the need for paradigm shifts in three areas. First, the too-frequent focus on how to best promote learning in the target language needs to make way for how to best promote multilingual proficiency up to advanced knowledge of several languages. Second, it is time to demystify the “mother tongue” or “native” or “first” language. Finally, the field needs to conceptualize “non-native speaking” teachers for their essential qualities—their multilingual proficiency—to form a better valuation of their actual language teaching skillset.

Imagining Gender in Nineteenth-Century Fairy Tales by Hans Christian Andersen and Richard Henry Stoddard
Authors: Holmgren Troy Maria
Published: November 2020

Fairy tales have often been controversial, and today much of the controversy appears to revolve around gender issues. With a focus on gendered appearances and relationships, this article examines Hans Christian Andersen’s ‘Tommelise’ and ‘The Snow-Queen’ as well as Adventures in Fairyland (1853), a book of fairy tales written by one of Andersen’s admirers and promoters in nineteenth-century USA, Richard Henry Stoddard. Depictions of female characters in these tales are varied, with protagonists not always adhering to the feminine beauty ideal. The portrayal of both girls and boys are sometimes influenced by the notion of the Romantic child, which seems to tone down gender differences in descriptions of characters. Some of Stoddard’s fairy tales have a masculinist bias, but on the other hand his tales often go beyond the happily-ever-after ending. Indeed, a few of his fairy tales are remarkably explicit about adult erotic love, physical attraction, and sexual desire. So, when viewed through the lens of gender, both Andersen’s and Stoddard’s nineteenth-century literary fairy tales offer a twenty-first-century reader quite a few surprises and much food for thought and discussion.
Commitment and Class: Female Working-Class Activists in Three Suffragette Novels
Authors: Paul Ronald
Published: November 2020

The article examines the relationship between social class and political commitment in three Suffragette novels written by women who were themselves actively engaged in the Women’s Social and Political Union. The novels are Elizabeth Robins’s The convert (1907), Gertrude Colmore’s Suffragette Sally (1911) and Constance Elizabeth Maud’s No surrender (1911). In these fictionalized depictions of Suffragette activism, I argue, it is the female working-class characters that support more politically uncompromising modes of action in the struggle for female emancipation. There is also a narrative progression throughout the three novels which, I claim, dramatizes the clash of personal loyalties and political commitment that reveals more clearly the fundamental contribution of working-class women in what has been previously viewed as a predominantly middle-class movement.
‘That little space’: Locating Abdulrazak Gurnah in the Global Literary Marketplace
Authors: Falk Erik
Published: November 2020

The transformation of the publishing world in recent decades—which includes, among other things, the increasing significance of large retail outlets, the emergence and establishment of literary agents, and the merger of publishing houses into large media corporations—has been amply documented. Among the consequences for postcolonial literary fiction, and African English-language fiction, which is the subject here, are increasing use of the author as a public figure and marketing device, and heightened expectations on cultural representativity that link authors to particular places and cultures. With a focus on the initial and middle phases of his career, this article discusses the ways in which East African author Abdulrazak Gurnah has responded to such pressures in his novels and in essays and articles. It shows how both the form and the content of Gurnah’s writing exemplify a double effort to complicate ideas which frame authors and their texts through culture-specific identities and the seemingly opposite, generalizing notion of the postcolonial’ author which flattens history—a strategy of ‘self-authorization’ which can be seen as Gurnah’s critical resistance towards received categories used in both book marketing and postcolonial authorship. In a further twist, this resistance is in some tension with Gurnah’s choice to write in English and use an unmarked linguistic style and register since these seemingly align with marketing interests and enable easy translation which facilitates the global circulation of his books.
Remembering the Future: Sion Sono’s Science Fiction Films
Authors: Jacobsson Andreas
Published: November 2020

This article focuses on two science fiction films by the Japanese film auteur Sion Sono: The Land of Hope (2012) and The Whispering Star (2015). The aim of the article is to analyse the two films as a critique of the aftermath to the 3/11 disaster in Fukushima in 2011; highlighting the potentially disastrous ecological effects that the meltdown of nuclear power plants can have on the future for humanity and life on earth. The analytical framework is based on the film philosophical concepts belief in images and time, the film studies concept slow cinema and the science fiction concept counter-futurism. The analysis of the films clarifies how time and duration is used to problematise a future without an actual future in relation to a nuclear disaster. One conclusion is that Sono’s entries in the genre can be regarded as a contemporary phase of the Japanese ‘imagination of disaster’, adding new counter-futurist critical ideas to the cross-section of film-philosophy and science fiction film.
The Art of Judgment: Postcritique and the Particular Case
Authors: Ullén Magnus
Published: November 2020

The present article critiques the so-called postcritical position for refusing to acknowledge the literariness of literature. As a case in point, it considers Toril Moi’s Revolution of the ordinary: literary studies after Wittgenstein, Austin, and Cavell, which has been greeted as a pivotal specimen of postcritique. Like other practitioners of postcritique, Moi would replace literary theory with an art of judgment, based upon good faith in, rather than suspicion of, the literary text. In theory, all that is needed to practice this art of judgment is a willingness to pay close attention to the specifics of the particular case. In practice, however, the postcritical claim to go beyond ‘the hermeneutics of suspicion’ is compromised by its refusal to confront the literariness of literary text, as the present essay demonstrates by subjecting Moi’s own reading of the particular cases of Paul de Man and Norwegian terrorist Anders Behring Breivik to rhetorical analysis.
The role of ultrasound in the differential diagnosis of liver tumors
Authors: Katrich A. N. , Polshikov S. V.
Published: November 2020

Background. Liver lesions are increasingly found in a huge number of patients. Ultrasound (US) is the method of choice in liver lesion characterization. The limitations of traditional US techniques are well known. Multiparametric ultrasound (MPUS) includes multiple facets of the US examination, and their combination can significantly improve the diagnostic capabilities of the method.

Objective. To evaluate the capabilities of MPUS in the differential diagnosis of liver tumors.

Material and Methods. A retrospective analysis included 172 patients with morphologically confirmed liver tumors. All patients underwent an MPUS examination.

Results. Traditional US techniques have a rather low specificity in the differential diagnosis of liver neoplasms: the sign of “contour clarity” was typical for hemangiomas, hepatocellular adenomas (HCA), liver metastases and was recorded in 82, 100, 96% cases, respectively; heterogeneous echostructure was noted in all nosological entities, groups of hepatocellular carcinomas (HCC), liver metastases and HCA were characterized by foci of various types of echogenicity. Specific symptoms were discovered in patients with liver metastases (32%) and focal nodular hyperplasia (FNH) (96%). Intratumoral blood flow was recorded in 34 (19.7%) cases. The study of spectral characteristics was possible only in 11 (6.4%) patients. Statistically significant differences in contrast-enhanced US parameters “contrasting onset in focus” were found between the groups “FNH & hemangioma” (р < 0.000046), “FNH & HCA” (р < 0.006293), “MTS & FNH” (р < 0.028125), “FNH & HCC” (р < 0.024933), “maximum fill-in time” – “FNH & hemangioma” (р < 0.012590), “FNH & HCC” (р < 0.007983), “MTS & HCC” (р < 0.000243). Statistically significant differences in the wash-out time were obtained in “MTS & HCC” and “MTS & HCA” groups.

Conclusion. Conventional US should be used as basic screening, follow-up and navigation in the neoplastic biopsy. Contrast-enhanced US within MPUS is currently a well-established technique which allows a more precise and confident diagnosis of liver tumors.
Colorectal reconstructions following Hartmann’s procedure: challenges and solutions
Authors: Igolkin A. N. , Polovinkin V. V.
Published: November 2020

The availability of a stoma after Hartmann’s procedure significantly limits the patient’s ability to work and worsens the quality of his/her life, as it partially isolates him/her from society. Performing plastic colon surgeries is challenging due to the active formation of intestinal adhesions and low rectal stump. At present many different devices, equipment, operating methods, and techniques have been proposed for reconstructive surgery on the colon. However, the issues of access to the surgical area, providing constant visual control, both at the stage of isolation for the short stump of the rectum in the narrow pelvis and in formation process of low colorectal anastomosis, are not covered in the scientific publications.

Published: November 2020

With it being considered as avalue-added activity,theInternal Auditfunction (IAF)of a firm is one of the most important functionsin anorganization. During the last decade,the roleof this particular functionhas become very useful,especially in creating awareness regarding the Prevention, Detection and Assessment (PD&A) of fraudulent activities. In many countries, carrying out an Internal Audit isa legal compulsion for public companies, in orderto establish an effective,and efficient IAF.This study aims to explore the relationship between the various attributes of IAF(effectiveness, independence, staff training, qualification and experience),and the PD&A of fraudulent activitiesin Pakistan. For this purpose, the convenientsampling technique,for data collection,is used and the questionnaires are collected fromtherespondents belonging to Pakistan. The questionnaire has been prepared in the form of a Likert scale. Respondents for this study include (1) staff members working in the Internal Audit (IA),finance and accounting departments of the companies listed on the Pakistan Stock Exchange(PSX), and(2) staff members of firms that are engaged in external statutory audit in Pakistan. Descriptive statistics show the details regarding the demographic questions, IAFand PD&A ofthefraudulent activitiesthat take place in the companies. Moreover, in order to get to the effective and relevant results, the regression analysis is performed in order to find out if there exists any relationship between these variables. The results show that all five independent variables positively affect the PD&A of fraudulent activities. However, three of the independent variables (IAE, IAT, and IAQ) are statistically significant,whereas twoof thevariables taken into account (IAI, and IAE) are statistically insignificant. It is recommended thattheIAFshould be more independent,and effectiveso asto attainthe required results. Moreover, firms should also focus on the qualificationsand proper training of the staff that are responsible forexecutingthe IAF.
Noise Trading and Single Stock Futures: Modifying Sentana & Wadhwani’s Model
Authors: Riaz Malik Imran , Shah Attaullah
Published: November 2020

Derivatives,and their influence on the dynamics of underlying stock markets,is an interesting topic of debate, which predates their introduction. The unresolved influence of derivatives on their underlying stock markets still intrigues many. In this regard, researchers/stake holders are still curious about the (de)stabilizing influence of derivatives on the overall market. In disposition of these observations, two contradicting hypothesis have been studied widely and have remained the focus of attention in several theoretical and empirical studies. These hypotheses are explained in several ways. Among many, one explanation refers to the destabilizing influence of derivatives,due to the enhanced involvement of noise traders, after the introduction of derivatives.This aspect remains the topic of discussion for this study. After the formal introduction of the SSFs (Single Stock Futures) in Pakistan, this topic became a cause of concern for the stakeholders of this market as well. Hence, this study attempts to tap into this aspect of the de(stabilization) debate,by proposing a modified version of the famous Sentana & Wadhwani (1982)model. In order to tap the potential shortcomings of the S&W model, this study contributes to the extant literature in several ways: 1) It adds the feature of trading volume in the model to analyze and study the potential movement of noise traders from spot to futures market,due to the ease of trading that the futures markets offer, 2) the new, modified model adds a lagged term for returns in order to tap the potential asynchronous inefficiencies, 3) it considers the Generalized Error Distribution (GED) instead of the Gaussian Distribution, in order to realize the fact that returns are not normally distributed. Generally speaking, the modified version of the model not only extends the original model in terms of its explanation, but also empirically tests this aspect in the Single Stock Futures (SSFs) market of Pakistan. This model tested whether SSFs promote,or inhibit the noise trading post-SSFs. After putting it to test, the newer model did not report any negative or positive impact of the introduction of SSFs on the underlying stocks. This may conclude that the proclaimed (de)stabilizing role of the SSFs,in the context of Pakistan,is not justified.
Determining the Impact of Intangible Assets on Intellectual Capital and Competitive Advantage in Banking
Authors: Sadiq Ramla , Nosheen Safia
Published: November 2020

This paper carries out the empirical tests in order to validate the hypothesis that resource intangibility, in the form of intangible assets, contributes towards the intellectual capital, and the competitive advantage in the banking sector. Furthermore, it also determines whether the intangibility of a banks' resources contribute towards the sustainability of the competitive advantage. Finally, it determines which aspects of the banking performance, the intangible assets actually contribute to. In this context, this research utilizes the secondary data, which is extracted from the annual reports of commercial banks that are listed on the primary stock exchanges of Pakistan. The sample that is taken into consideration is divided into two main categories in order to carry out the analysis. These categories include the classification into the Islamic banks and the conventional banks. The Islamic window operations have not been included in the analysis,as the details required for the variable calculations are not consistently available. Moreover, this bifurcation in the sample is also a unique aspect of this research,as the prior literature primarily focuses on the determinants of the intellectual capital in the banking sector. However though, there is no direct study regarding the differences in the resource intangibility in the Islamic banks and the conventional banks, and their subsequent impact on the intellectual capital and competitive advantage. The time frame for the analysis is taken from the year FY2008-FY2018 .Also,the findings of this study lead to striking implications for both the Islamic banking theory and the managerial practices in the banking sector of Pakistan. The resource intangibility is to be managed very differently across both categories. Where the intangible assets represent a significant contribution to both the intellectual capital and the competitive advantage for Islamic banks, the yal sore present a negligible impact on the intellectual capital,and the competitive advantage for conventional banks. This holds true for the conventional performance measures that are taken for the banking sector as well, as shown in the robustness analysis.

MODELLING THE RELATIONSHIP BETWEEN POPULATION GROWTH AND INDUSTRIAL OUTPUT IN NIGERIA: AN AUTO-REGRESSIVE DISTRIBUTIVE LAG APPROACH (1980-2017)
Authors: Egbulonu K. G. , Duru Erasmus E. , Dim Henry C.
Published: November 2020

This research work focuses on the relationship between population growth and industrial output in Nigeria for the period 1980 to 2017. It is particularly interesting to study the relationship between population growth and industrialization in Nigeria because at present, Nigeria is making rapid effort to advance her economy while undergoing a demographic transition that has been projected to be geometric in nature. This research developed an Auto-regressive Distributive Lag (ARDL) model using Index of Industrial Output as the dependent variable and Population growth rate, Birth rate, Total Labour Force (as a percentage of total population that are employed), Capacity Utilization and Manpower Development Index as the independent variables. The data was obtained from the World Bank, the National Population Commission and the Central Bank of Nigeria Statistical Bulletins (various issues). The findings reveal that Population Growth Rate has an inverse relationship with Industrial Output both in the short run and in the long run while Total Labour Force and Capacity Utilization also decrease Industrial Output both in the short and long-run periods. Since the Bounds test reveals a long-run relationship between population and Industrial Output, we recommend a renewed determination and political will to implement the National Policy on Population for sustainable development that outlines a sectoral strategy to manage our rising population.

Az Egyesült Államok, mint globális nagyhatalom világszerte kiterjedt nemzetközi kapcsolatokkal rendelkezik. Érdekeinek érvényesítésében pedig nagy szerepet játszik, hogy a világ különböző pontjain jelentős gazdasági és katonai jelenlétet tart fenn. Ezzel szemben a Magyarországgal szomszédos Románia, a világpolitikában kisállamnak minősül. Ugyanakkor nem alábecsülendő, hogy jelentős szerepet játszik Kelet-Közép Európa biztonságának garantálása szempontjából. Magyarország keleti szomszédjaként, illetve NATO és EU szövetséges tagállamként sokkal nagyobb figyelmet érdemel hazai szintéren is, mint amilyet az elmúlt évtizedekben kapott. Egyrészt az említett biztonsági kockázatok kivédésében, másrészt a Magyarországot és Romániát egyaránt érintő vitás és egyéb kérdések kooperatív rendezése végett. Jelen elemzést az elmúlt évtizedekben felélénkült, sikeresnek mondható amerikai-román kapcsolatok eredményei ihlették.

Published: November 2020

Számos – általában geopolitikai indíttatású – kísérlet irányult már a történelem során a Közép-Európa fogalom meghatározására. Cikkünkben mi is egy új lehatárolás létrehozatalára törekszünk, azonban történelmi és geopolitikai megközelítés helyett statisztikai módszerekkel alakítottuk ki a térség határait. Először a térséghez kapcsolódó koncepciók gyökereit és jelenkori értelmezéseit mutatjuk be. Ezt statisztikai elemzés követi, amely során jóléti, életmódbeli és attitűdbeli adatok mentén vizsgáljuk Európa országait, és K-közép klaszteranalízissel osztjuk őket csoportokra. Az így kapott klaszterek segítségével határozzuk meg Európa legfőbb belső határvonalait és alakítjuk ki saját Közép-Európa fogalmunkat. Konklúziónk, hogy mivel ez számos téren eltér a korábbi koncepcióktól, így javasolt a Közép-Európa fogalom újragondolása.

The borehole shrinkage of swelling rock in coalmine is a complex problem affected by the combination of multiple fields, such as humidity field and stress field. By establishing the equilibrium equation of swelling rock borehole in coalmine, considering the expansion and softening properties, an elastic-plastic mechanics analysis was carried out, and the plastic zone radius and radial displacement of swelling rock borehole in coalmine were determined under the combination of humidity field and stress field. Taking the floor rock roadway in the 8# coal seam of Songzao Coalmine in Chongqing as an example, the influence laws of water content, ground stress, and water pressure in the hole on the borehole shrinkage were studied. The results show that, with the increase of water content of the surrounding rock, the radius of plastic zone and radial displacement of borehole wall gradually increase. Both the humidity expansion and softening have an important influence on borehole shrinkage in coalmine, and the radial displacement of borehole wall under the combination of swelling and softening is greater than that of only considering expansion or softening. With the increase of ground stress, the radius of plastic zone and radial displacement of borehole wall gradually increase, showing a nonlinear increasing relation. The larger the water pressure in the borehole, the smaller the radius of plastic zone and radial displacement of borehole wall, and properly increasing the water pressure in the borehole can effectively control the borehole shrinkage. The accuracy of theoretical analysis was further r verified by similar model tests. The results can provide a theoretical basis for solving the problem of borehole shrinkage in the swelling rock of coalmine.

Since pricing is recognized as one of the most important tools for profit optimization, price competition is one of the major issues facing companies. Determining the appropriate inventory control policy and optimal selling price of various products is a major subject of scientific and industrial research in recent years. On the other hand, today, some of the products on the market have the potential to become obsolete, which means that their demand is reduced at once with the development of new technology. Therefore, determining the optimal price and inventory policies for these types of products is very crucial. In this research, an inventory control model for a retailer is formulated to optimize the inventory and pricing decisions for profit maximization simultaneously. According to the problem assumptions, demand is price-dependent, the time that product becomes obsolete has an exponential distribution, the type of product obsolescence is also sudden, and the retailer determines the optimum price and order quantity of replenishment. The proposed model has a nonlinear profit function, in which the partial derivatives of the objective function are used to reach the optimal value. Finally, the effects of various parameters such as the speed of obsolescence, the holding cost of each item unit, the cost of selling obsolete items, and the purchasing price were studied on the total profit. For this purpose, a numerical example is solved along with a sensitivity analysis to evaluate the validity of the model and investigate the effect of parameters on the optimal solution. The key achievement of this study was the development of a new model and providing a solution to determine the optimal values of product sales price and retailer order quantity with maximum profit.

In this study, a real-world isolated signalized intersection with a fixed-time signal control system is considered. The signal timing plans are arranged regardless of the traffic density, and these plans cause delays in vehicle queues. To increase the efficiency of the intersection, an adaptive traffic signal control system is proposed to manage the intersection. To find the appropriate adaptive green times for each lane, simulations are performed by traffic simulation software using vehicle arrivals and other information about vehicle movements gathered from the real-world intersection. Then, a hybrid radial basis function neural network is developed to forecast the adaptive green times, which is trained and tested with historical arrivals and simulation results. The performance of the proposed network is compared with well-known data mining classification methods, such as support vector regression, k-nearest neighbors, decision tree, random forest, and multilayer perceptron methods, by different evaluation parameters. The comparison results provide that the developed radial basis function neural network outperforms other classification methods and can be successfully used for forecasting adaptive green times as an alternative to complex unsupervised classification methods.

The digital level (SOKKIA SDL-30) and total station (SOKKIA CX-105) are highlighted as examples of digital surveying instruments. In this study, it is clarified how some surrounding factors can affect their efficiency such as vibration, sunlight, and its direction, temperature, and battery capacity. Through vibration testing as one of these factors ,both the digital level and the total station using the reflector-less were exposed to vibration up to 25 KHZ/Sec, the average and the standard deviations elevation error for the digital level increased by 2 times at 80 m distance , and the average and the standard deviations positioning error increased 3 times for the total station using the reflector-less total at 80 m distance between the instrument and bar code. 64.3% and 51.25% are the increasing ratios in average error for digital level and total station with reflector-less prism by testing the effect of sunlight and its position. The increase in temperature leads to an increase in the average error with 150 % and 66.6% for digital level and reflectorless total station. Finally, the lack of battery efficiency led to a shortage of accuracy of the Surveying Instruments.

The paper deals with regional and structural analysis of internal migration of the population in southern Bohemia between 1992-1998 in relation to the developments in the whole Czech Republic. As southern Bohemia, we understand the area of the contemporary Southern Bohemia Region. When evaluating migration in the given area, we used some basic indicators of demographic statistics, such as number of immigrants, number of emigrants, migration turn-over and net migration. The analysis also includes identification of main migration flows, the issue of migration motivation and an evaluation of the impact of migration on some structural characteristics of population, such as sex, age and educational structure.

O presente estudo teve o objetivo de comparar a autonomia funcional de mulheres idosas, praticantes e não praticantes de hidroginástica. A amostra foi composta por 19 mulheres, com idades entre 61 e 80 anos, divididas em dois grupos (GPH – grupo praticante de hidroginástica, GNPH – grupo não praticante de hidroginástica). A avaliação da autonomia funcional foi realizada utilizando o protocolo GDLAM (Vale et al., 2006), constituído pelos testes de caminhar 10 metros (C10m), levantar-se da posição sentado (LPS), levantar-se da posição decúbito ventral (LPDV), levantar-se da cadeira e locomover-se pela casa (LCLC). A análise estatística foi realizada por meio do teste t-Student para amostras independentes, com o nível de significância de α<0,05. O GNPH levou o dobro do tempo para realizar as tarefas de LPS, LPDV e LCLC ao ser comparado com o GPH (p<0,05). Contudo, ao desempenhar o teste de C10m, o mesmo não se revelou diferente estatisticamente (p>0,05). Conclui-se, baseado nos dados revelados, que a hidroginástica pode ser uma atividade física utilizada para prevenir o declínio funcional, e, ainda, conservar a autonomia funcional de mulheres idosas.
