Bridging a Survey Redesign Using Multiple Imputation: An Application to the 2014 CPS ASEC
Authors: Rothbaum Jonathan 
Published: February 2017

Abstract
The Current Population Survey Annual Social and Economic Supplement (CPS ASEC) serves as the data source for official income, poverty, and inequality statistics in the United States. In 2014, the CPS ASEC questionnaire was redesigned to improve data quality and to reduce misreporting, item nonresponse, and errors resulting from respondent fatigue. The sample was split into two groups, with nearly 70% receiving the traditional instrument and 30% receiving the redesigned instrument. Due to the relatively small redesign sample, analyses of changes in income and poverty between this and future years may lack sufficient power, especially for subgroups. The traditional sample is treated as if the responses were missing for income sources targeted by the redesign, and multiple imputation is used to generate plausible responses. A flexible imputation technique is used to place individuals into strata along two dimensions: 1) their probability of income recipiency and 2) their expected income conditional on recipiency for each income source. By matching on these two dimensions, this approach combines the ideas of propensity score matching and predictive means matching. In this article, this approach is implemented, the matching models are evaluated using diagnostics, and the results are analyzed.
Adjusting for Misclassification: A Three-Phase Sampling Approach
Authors: Sang Hailin , Lopiano Kenneth K. , Abreu Denise A. , Lamas Andrea C. , Arroway Pam , Young Linda J. 
Published: February 2017

Abstract
The United States Department of Agriculture’s National Agricultural Statistics Service (NASS) conducts the June Agricultural Survey (JAS) annually. Substantial misclassification occurs during the prescreening process and from field-estimating farm status for nonresponse and inaccessible records, resulting in a biased estimate of the number of US farms from the JAS. Here, the Annual Land Utilization Survey (ALUS) is proposed as a follow-on survey to the JAS to adjust the estimates of the number of US farms and other important variables. A three-phase survey design-based estimator is developed for the JAS-ALUS with nonresponse adjustment for the second phase (ALUS). A design-unbiased estimator of the variance is provided in explicit form.

Published: February 2017

AbstractBackground:The purpose of this study was to analyze the bone age and the upper extremity segmental lengths between the affected and the unaffected side and to reveal the correlation between the difference of bone age and the upper limb length discrepancy in the unilateral spastic cerebral palsy (CP). We also evaluated the relationship between difference of bone age and hand function.Methods:Seventy-eight patients participated in this study. The bone ages of hand-wrists of the patients were determined by the Greulich and Pyle atlas. Upper extremity segmental lengths were measured by radiograph. The side-to side length discrepancy was calculated as a percentage. Hand function was classified according to the Manual Ability Classification System (MACS).Results:There was significant difference in the bone age between the affected and unaffected side (p<0.001). Segmental lengths of the upper extremities showed significant differences between the affected and unaffected side (p<0.001). The hand function of 56 patients was evaluated by MACS and the MACS level showed correlation with difference of side-to-side bone age (r=0.29, p=0.03) and all segmental upper limb length discrepancies (p<0.05). The hand function in the bone-age-delayed group was significantly better than the hand function in the bone-age-symmetrical group (p<0.01).Conclusions:The bone age of the affected side compared to the unaffected side is delayed and the hand function of the affected side is correlated with the difference of side-to-side bone age and the upper limb length discrepancy. Hand function might be helpful for predicting potential limb shortness and delayed bone age.

Analysis of the Voting Behaviour of Czech Members of European Parliament in Areas of the Europe 2020 Strategy
Authors: Mocek Ondřej 
Published: February 2017

Abstract
Aim of this paper is to analyse the behaviour of Czech MEPs in the topics related to Europe 2020 Strategy. This Strategy is one of the most important documents of recent decade on the European level and it is not so often studied on the level of the European Parliament. The purpose of this text is to find out if Czech political parties in the European Parliament are cohesive or not. The second question is related to the voting patterns, whether Czech MEPs create some kind of voting coalitions or not and if these coalitions reflect the national coalition. Methodology is based on the analyses of roll-call votes. The research period is the first two years of the 8th term of the European Parliament.
Business‑Firm Parties and the Czech Party System after 2010
Authors: Just Petr , Charvát Jakub 
Published: February 2017

AbstractThe case study presented in this paper applies the business-firm party concept to two political entities active in the Czech party system after 2010: the Public Affairs Party (VV) and the Action of Dissatisfied Citizens (ANO 2011) movement. We assess whether these actors meet the criteria of the business-firm party model and, thus, whether they can be considered representatives of this type of political party in the Czech Republic. The study concludes with a comparison of VV and ANO 2011 as two possible variations on what is known as the business-firm party model.
Friends forever? The Role of the Visegrad Group and European Integration
Authors: Schmidt Andrea 
Published: February 2017

Abstract
The Visegrad Group celebrated its 25th anniversary in February 2016. Established as an initiative of three statesmen from the Central and Eastern European (CEE) region, this cooperation has experienced booms and crises. The aim of this paper is to analyse the function of this regional integration in the years following the end of bipolar system as Visegrad Group members headed down the road to Euro-Atlantic integration. To this end, I apply different theoretical approaches and attempt to explain the influence of key former politicians as well as new scenarios for the Visegrad Group’s position in the European Union. This analysis also covers the latest foreign policy changes and challenges facing CEE due to the involvement of a wider region that creates a counter-balance to the core EU. Statistical data and official documents from the Visegrad Group’s website strengthen these findings.
Two novel thorium organic frameworks constructed by bi- and tritopic ligands
Authors: Chen Fei , Wang Congzhi , Lan Jianhui , Ji Yanqin , Chai Zhifang 
Published: February 2017

Abstract
Two thorium organic frameworks, Th(BDC)2 and Th(OH)(BCPBA) have been hydrothermally synthesized using 1,4-benzenedicarboxylic acid (H2BDC) and 3,5-bi(4-carboxyphenoxy)benzoic acid (H3BCPBA), respectively. The obtained two compounds were determined by single-crystal XRD, and they exhibited two new topologies. Th(BDC)2 shows a 3-dimensional (4,4,8)-connected framework with the Schläfli symbol of (414·612·82)(42·63·8)(44·62), and it is a mononuclear thorium(IV) complex. Th(OH)(BCPBA) possesses a (4,6)-connected topology with the Schläfli symbol of (415)2(46)3, and it has a dinuclear thorium(IV) asymmetric unit with the shortest Th–Th distances. Viewing along suitable directions, channels with different shapes can be found in the obtained two frameworks. Based on calculation with PLATON, the amount of void space is 21.9% and 13.5% in Th(BDC)2 and Th(OH)(BCPBA), respectively. Density functional theory (DFT) studies revealed that the metal-ligand interactions were mainly of ionic character in both compounds and the hydroxyl ions might play an important role in the stability of dinuclear thorium(IV) of Th(OH)(BCPBA).
Prognostic significance of uPA/PAI-1 level, HER2 status, and traditional histologic factors for survival in node-negative breast cancer patients
Authors: Dovnik Nina Fokter , Takac Iztok 
Published: February 2017

Abstract

Background
The association of HER2 status with urokinase plasminogen activator (uPA) and plasminogen activator inhibitor 1 (PAI-1) levels raises the question whether uPA/PAI-1 level carries additional clinically relevant prognostic information independently from HER2 status. The aim of our study was to compare the prognostic value of uPA/PAI-1 level, HER2 status, and traditional prognostic factors for survival in node-negative breast cancer patients.

Patients and methods
A retrospective analysis of 858 node-negative breast cancer patients treated in Maribor University Clinical Center, Slovenia, in the years 2000–2009 was performed. Data were obtained from patient medical records. The median follow-up time was 100 months. Univariate and multivariate analyses of disease-free (DFS) and overall survival (OS) were performed using the Cox regression and the Cox proportional hazards model.

Results
In univariate analysis, age, tumor size, grade, lymphovascular invasion, HER2 status and UPA/PAI-1 level were associated with DFS, and age, tumor size, grade, and uPA/PAI-1 level were associated with OS. In the multivariate model, the most important determinants of DFS were age, estrogen receptor status and uPA/PAI-1 level, and the most important factors for OS were patient age and tumor grade. The HR for death from any cause in the multivariate model was 1.98 (95% CI 0.83–4.76) for patients with high uPA and/or PAI-1 compared to patients with both values low.

Conclusions
uPA/PAI-1 level clearly carries an independent prognostic value regardless of HER2 status in node-negative breast cancer and could be used in addition to HER2 and other markers to guide clinical decisions in this setting.
Echocardiography and cardiac biomarkers in patients with non-small cell lung cancer treated with platinum-based chemotherapy
Authors: Omersa Daniel , Cufer Tanja , Marcun Robert , Lainscak Mitja 
Published: February 2017

Abstract

Background
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and remains an important cause of cancer death worldwide. Platinum-based chemotherapy (PBC) for NSCLC can modify outcome while the risk of cardiotoxicity remains poorly researched. We aimed to evaluate the incidence and severity of cardiac injury during PBC in patients with NSCLC and to identify patients at risk.

Methods
This was a single-centre, prospective, observational study of patients with early and advanced stage NSCLC referred for PBC. In addition to standard care, patients were examined and evaluated for cardiotoxicity before the first dose (visit 1), at the last dose (visit 2) and 6 months after the last dose of PBC (visit 3). Cardiotoxicity (at visit 2 and 3) was defined as increase in the ultrasensitive troponin T, N-terminal pro-B type natriuretic peptide or decrease in left ventricular ejection fraction (LVEF).

Results
Overall, 41 patients (mean age 61 ± 9; 54% men; 68% advanced lung cancer) were included. The median number of PBC cycles was 4. During the study period, there were no incidents of heart failure, and 3 deaths caused by tumour progression were recorded. The mean values of biomarkers and LVEF did not change significantly (p > 0.20). However, 10 (25%) had cardiotoxicity which was independently associated with a history of ischemic heart disease (p = 0.026).

Conclusions
In NSCLC, cardiac assessment and lifestyle modifications may be pursued in patients with a history of cardiac disease and in patients with longer life expectancy.

Abstract

Background
The aim of the study was to retrospectively evaluate the symptom control, tumour response, and complication rate in patients with liver-predominant metastatic neuroendocrine tumours treated with transarterial chemoembolization using doxorubicin-eluting superabsorbent polymer (SAP) microspheres.

Patients and methods
Patients with neuroendocrine liver metastases who underwent hepatic transarterial chemoembolization using doxorubicin-eluting SAP-microspheres (50–100 μm Hepasphere/Quadrasphere Microsphere® particles, Merit Medical, South Jordan, Utah, USA) were included in this study. Pre-and post-procedure imaging studies were evaluated to assess short and intermediate-term tumour response using modified RECIST criteria. Symptom relief and procedure-related complications were evaluated.

Results
A total of 27 embolization procedures were performed on 17 patients. Twelve of 17 patients (70%) were symptomatic, including carcinoid syndrome (n = 8) and severe, uncontrollable hypoglycemia (n = 4). Eight of 12 patients (67%) had complete symptom relief, and the remaining 4 (33%) had partial relief. One patient developed ischemic cholecystitis (6%). No other hepatobiliary complications occurred. Short-term and intermediate-term imaging follow-up was available for 15/17 patients (88%) and 12/14 patients (86%) respectively. At short-term follow-up (< 3 months), 14 patients (93%) showed partial response and the remaining patient had progressive disease (7%). At intermediate-term imaging follow-up (> 3 months), partial response, stable disease and progressive disease were found respectively in 7 (58%), 3 (25%) and 2 (17%) patients.

Conclusions
Chemoembolization with doxorubicin-eluting SAP-microspheres is a safe and effective treatment option for neuroendocrine liver metastases and is associated with a low complication rate. In particular, no clinically evident liver necrosis or bile duct complications were encountered.
School Mediators in the Romanian Education System. A Discussion on Their Role in Addressing Educational Inequalities
Authors: Pop Florina , Balea Bianca 
Published: February 2017

Abstract
Based on findings from the project ‘Socio-graphic mapping of the Roma Communities in Romania for a community-level monitoring of changes with regard to Roma integration’, the article analyses the role of school mediators in influencing school practices for the reduction of the inequalities Roma students face within the education system. This study investigates the school mediators’ perception of causes and solutions for the difficulties Roma students face within the education system, while keeping in mind the current legislation and the public discourse on Roma. In order to gain a comprehensive understanding, we also investigate school mediators’ perception towards their work, as well as the manner they evaluate collaboration with colleagues, Roma families and other local stakeholders. Our findings illustrate that the school mediator carries out a multitude of tasks sometimes only partly related to the field of school mediation. At the same time, school mediators engage in a type of public discourse with regard to Roma which highlights individual responsibility and merits as solutions in order to overcome disadvantage. With regard to work satisfaction, although school mediators are poorly trained and they deal with a difficult and high amount of work, they report being highly satisfied with some aspects of their work.
Saying it again: enhancing clarity in English as a lingua franca (ELF) talk through self-repetition
Authors: Kaur Jagdish 
Published: February 2017

AbstractRecent research into the use of English as a lingua franca (ELF) in international settings reveals that its multilingual, multicultural participants rely on various interactional practices to negotiate meaning and arrive at shared understanding. In this regard, repetition, which has been identified as a widely used multifunctional procedure that facilitates the production, comprehension, and interaction processes in communication, has been shown to play a crucial role both in pre-empting and resolving understanding problems. This paper reports on a study conducted to investigate further how same-speaker repetition in an ongoing turn may be used to manage the lingua-cultural diversity inherent in the ELF situation and promote effective communication. Fifteen hours of audio-recorded naturally occurring ELF conversations in an academic setting were analyzed using conversation-analytic procedures. Fine-grained analyses of the data show that speakers repeat their speech in ways that can enhance the clarity of expression, which may contribute to increased recipient understanding. Specifically, the speakers employ parallel phrasing, key word repetition, combined repetition and repaired repetition that result not only in redundancy but more importantly in added prominence or the foregrounding of segments of talk that are oriented to as crucial in the meaning-making process.
Pointing gestures in video blogs
Authors: Frobenius Maximiliane 
Published: February 2017

AbstractVideo blogs are a form of CMC (computer-mediated communication) that feature speakers who talk into a camera, and thereby produce a viewer-directed performance. Pointing gestures are part of the resources that the medium affords to design vlogs for the absent recipients. Based on a corpus of 40 vlogs, this research categorizes different kinds of common pointing actions in vlogs. Close analysis reveals the role multimodal factors such as gaze and body posture play along with deictic gestures and verbal reference in the production of a viewer-directed monologue. Those instances where vloggers point at referents outside the video frame, e.g., elements of the Web site that represent alternative modes of communication, such as written comments, receive particular attention in the present study, as they require mutual knowledge about the shared virtual context the vlog is situated in.
Making learning ordinary: ways undergraduates display learning in a CMC task
Authors: Paulus Trena M. , Lester Jessica N. 
Published: February 2017

AbstractWe report findings from a discourse analysis study situated within a discursive psychology framework that examined how undergraduate nutrition science students took up a computer-mediated communication task in which they were asked to write about what they learned after attending a lecture. Students made learning displays by orienting to the lecture as a news receipt and making assessments of this new information in variable ways. Some did this by marking an extreme change of state through surprise tokens and realization patterns, functioning to position the new information as so extreme that anyone would have learned something new. Others displayed more neutral assessments of the information or claimed no change of state at all, functioning to distance themselves from having learned anything. Both strategies are ways of “doing being ordinary,” while completing a delicate task that presented them with a potential dilemma of displaying their learning for an invisible audience of their peers.
Papers, documents, and the opening of an academic supervision encounter
Authors: Svinhufvud Kimmo , Vehviläinen Sanna 
Published: February 2017

AbstractDespite a growing interest in the interaction in academic pedagogical settings, the role of texts in the actual interaction has not been systematically addressed. This article examines the practices and orientations through which written documents have a significant role in the openings of supervision encounters. We use videotaped recordings of supervision encounters and adopt conversation-analytical methodology to analyze the data.The analysis consists of two main foci: (i) the initial moments of the encounter prior to the actual supervisory activity, and (ii) the launching of the supervisory activity and the negotiation of what that activity will entail. We analyze the orientations toward the document as the necessary object of the joint activity and the prominent bodily orientation toward the papers during the initial moments of the encounter. Furthermore, when the participants move from the initial moments of the encounter toward the main activity, the paper document plays a major role in that interaction.In our conclusions, we summarize our observations as shared, implicit orientations related to the role of the document. These assumptions constitute the “implicit pedagogy” of the supervisory encounter. We will discuss some of the consequences of this type of pedagogy.
Words as weapons for mass persuasion: dysphemism in Churchill's wartime speeches
Authors: Crespo-Fernández Eliecer 
Published: February 2017

AbstractPoliticians and orators employ words as weapons in order to exert ideological control and make an audience believe something in an ostensive way. In this regard, taking critical-political discourse analysis and appraisal theory as theoretical frameworks, it is the purpose of this paper to shed some light on the dysphemistic words and expressions identified in some of the memorable wartime speeches over a crucial two-year period for the outcome of the Second World War (1940–1941) by one of the most outstanding British politicians and statesmen, Winston Churchill. As metaphors are pervasive in political discourse and vital to the language of leadership, special attention is given to the analysis of dysphemistic figurative language within Lakoff and Johnson's conceptual metaphor theory and Charteris-Black's critical metaphor analysis. The results obtained support the idea that Churchill's skillful use of dysphemism is closely connected with his overall political goals of instilling courage and inspiring confidence in his fellow countrymen in such difficult times for Britain as those of a war against the powerful Nazi Germany.
