Psychiatric Evaluation of Children and Adolescents With Left Ventricular Assist Devices

Objectives To evaluate the psychiatric symptoms of children equipped with a ventricular assist device (VAD) and follow them up for 6 months. With the shortage of donor hearts available for the treatment of end-stage heart failure, VADs have been used to provide temporary treatment until a heart becomes available. VADs provide external sources of power for mechanical circulatory support and are capable of sustaining life over weeks and months. This study provides preliminary details about the psychiatric symptoms and disorders of the first eight children equipped with a VAD in Turkey. Methods Eight pediatric patients who recently underwent VAD implantation, aged 1 to 16 years, were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia, Child Behavior Checklist, Children’s Depression Inventory, Beck Depression Inventory, and State-Trait Anxiety Inventory for Children and followed up for 6 months. Results In the first evaluation, five participants had a psychiatric disorder diagnosis. Two patients had adjustment disorder with depressive and anxiety symptoms; one had anxiety disorder, not otherwise specified; and two had major depressive disorder. The anxiety and depressive symptom levels in questionnaires were consistent with psychiatric diagnoses. Two patients had heart transplantation during the follow-up period. Conclusions To determine and treat psychiatric symptoms and disorders at an earlier stage, it is important for children and adolescents with a VAD and those who have undergone heart transplantation to be evaluated by a multidisciplinary consultation liaison team including psychiatrists, psychologists, consultant nurses, and counselors. Abbreviations VAD = ventricular assist device K-SADS = Kiddie Schedule for Affective Disorders and Schizophrenia CBCL = Child Behavior Checklist BDI = Beck Depression Inventory CDI = Children’s Depression Inventory STAI-C = State-Trait Anxiety Inventory for Children MDD = major depressive disorder AD = adjustment disorder PE.I = initial psychiatric evaluation PE.II = second psychiatric evaluation
The organizational career: not dead but in need of redefinition

The organizational career has been portrayed as increasingly irrelevant in a world where organizations are either unwilling or unable to offer job security, and where individuals are seeking greater independence and flexibility with regard to career development. In theory, new models of career, such as boundaryless or protean career, offer a better fit for both individuals and organizations. This paper argues, however, that not only does the organizational career still exist, but it is also still relevant and desirable. Rather than simply discarding it there is much to be learned from exploring how it has evolved and then redefining it to meet the needs of contemporary organizations.
A Note on Multi-Issue Two-Sided Bargaining: Bilateral Procedures

This note considers a two-sided multi-issue bargaining problem in which players that belong to the same "side" may have conflicting priorities regarding the different negotiated issues. The note examines different bilateral bargaining procedures and shows the different equilibrium settlement that they yield. In particular the note examines the posiibility that group heterogeneity (conflicting priorities) may be exploited in order to gain a better settlement.
A Qualitative Case Study of EFL Students' Affective Reactions to and Perceptions of Their Teachers' Written Feedback.

The present paper reports a qualitative case study of investigating EFL students’ affective reactions to and perceptions of their teachers’ written feedback. In addition, the study reported here also focuses on contextual factors that may influence students’ reactions to and perceptions of their teachers’ written feedback. Data were collected using multiple methods that included semi-structured interviews, think-aloud protocols, teachers’ written feedback, and students’ written essays. Results of data analysis revealed that EFL students showed some variations in their affective reactions to their teachers’ written feedback. The students perceived their teachers’ written feedback as useful and very important for the development of their writing skills. The students wanted their teachers to focus on all aspects of written texts when they provide written feedback. Contextual factors such as students’ past experience, teachers’ wording of written feedback, students’ acceptance of teachers’ authority, and teachers’ handwriting have their impact on EFL students’ affective reactions to and perceptions of their teachers’ written feedback.
An improved target tracking algorithm with two-phase

Aiming at the tracking failure in dynamic scene with fixed template and drift problem caused by using dynamic model in visual tracking, an improved target tracking algorithm with two-phrase is proposed. Dimension reduction on positive and negative samples is made in high dimension feature space using partial least squares (PLS), and then the appearance model of target is constructed in learned low dimension feature subspace. Target tracking is carried out within the Bayesian inference framework with two-phase: in first phase, the preliminary estimation of target location is achieved by using the principle of particle filter; in second phase, the adaptive benchmark model is adopted to determine the final target location. Experimental results demonstrate the effectiveness of the proposed algorithm.
Predictors of management accounting change in South Africa: Evidence from five retail companies

There is limited knowledge of management accounting practices and change in developing countries. This paper explores the processes of management accounting change in five South African retail companies by means of case studies. A number of factors have been identified from the contingency theory literature, which are applied in five cases to examine the management accounting changes and the reasons for them. The cases indicate considerable changes in the organisations’ management accounting practices during the last ten years. Recent environmental change in South Africa arising from government reform/deregulation policy and global competitive environments largely contributed to the management accounting change processes, which is consistent with contingency theory. This paper provides empirical evidence on which future research in less developed countries can be conducted.
Development of Back-Channel Etched In-W-Zn-O Thin-Film Transistors

Back-channel etched (BCE) thin-film transistors (TFTs) are developed using a novel oxide semiconducting material, In-W-Zn-O (IWZO). A bi-layer structure for the IWZO oxide semiconductor layer is proposed to realize both high resistance to back-channel etching damage and high TFT mobility. The developed IWZO BCE-TFTs exhibit high mobilities of up to 20.2 cm2/V·s.
Discussion of To Trade or Not To Trade: The Strategic Trading of Insiders around News Announcements

Korczak, Korczak and Lasfer (2010) (hereafter KKL) examine the likelihood and amount of corporate insider (company director) trading before a news announcement about a corporate event. The novel feature of the paper is that it examines insider trading after distinguishing between good and bad subsequent news announcements. The authors construct a unique dataset of 119,179 news announcements and 8,086 insider trades for 797 UK companies over the period 1999-2002. After separating out the non-confounding announcements, they divide the sample into 39,617 good news announcements and 38,634 bad news announcements, where the definition of good and bad news depends on the two-day stock market return around the day of the announcement. This good-bad classification is determined by how the stock market responds to the announcement relative to the value of the stock on the day prior to the announcement. They match these announcements with the shares traded by corporate insiders in the 30 days before the news announcement. This yields 4,083 good news events and 1,262 bad news events preceded by insider trading. KKL’s approach is then to use a logit analysis to examine the determinants of whether or not insiders trade before a news announcement (the occurrence of insider trading) and an OLS regression of the net quantity of insider trades in the month before the announcement to identify the determinants of the magnitude of insider trades. KKL record two major findings. First, corporate insider trading is more prevalent before good news than bad. Second, the quantity of insider trading before good news is a concave function of the information content (revealed at announcement of the corporate event). Insiders’ trades increase as the information content of the news increases, but it is argued due to regulatory scrutiny, for news announcements with large price impacts, the quantity of insider trading levels out.

A Theoretical Model of Cognitive Factors that Affect Auditors' Performance and Perceived Independence

Auditor independence is a guiding principle of the relationship between auditors and clients, and a key component of outsiders' acceptance of firms' financial statements. As recent accounting scandals have illustrated, the audit process is meaningless without the auditor's impartial judgement. While Kleinman, Palmon and various colleagues (1998, 2000a, 2001 and 2003) have developed a framework based on the behavioural science literatures to understand the auditor-client relationship, this framework excludes the effects of expertise, cognitive heuristics and affect on the outcomes of situations that might challenge auditor independence. This paper draws on the Mayer (2003) and Libby and Luft (1993) models and other literature to develop a cognitive model of factors that may affect perceived independence and auditor's performance. This model should help interested parties better understand situations that may impair the perceived independence of auditors. Suggestions for improving the auditor's reasoning process are presented, as are research suggestions.
A deep learning approach for optimizing content delivering in cache-enabled HetNet

In ultra-dense heterogeneous networks, caching popular contents at small base stations is considered as an effective way to reduce latency and redundant data transmission. Optimization of caching placement/replacement and content delivering can be computationally heavy, especially for large-scale networks. The provision of both time-efficient and high-quality solutions is challenging. Conventional iterative optimization methods, either optimal or heuristic, typically require a large number of iterations to achieve satisfactory performance, and result in considerable computational delay. This may limit their applications in practical network operations where online decisions have to be made. In this paper, we provide a viable alternative to the conventional methods for caching optimization, from a deep learning perspective. The idea is to train the optimization algorithms through a deep neural network (DNN) in advance, instead of directly applying them in real-time caching or scheduling. This allows significant complexity reduction in the delay-sensitive operation phase since the computational burden is shifted to the DDN training phase. Numerical results demonstrate that the DNN is of high computational efficiency. By training the designed DNN over a massive number of instances, the solution quality of the energy-efficient content delivering can be progressively approximated to around 90% of the optimum.
Temporary Chinese Migration to Madagascar: Local Perceptions, Economic Impacts, and Human Capital Flows

Adopting a human capital perspective with which to analyse the economic impacts of Chinese migration to Africa, this article investigates how temporary Chinese migrants are affecting domestic producers in Antananarivo, Madagascar. Since the first Chinese retailer opened a shop in Behoririka, Antananarivo’s ‘Chinatown’, in the mid-1990s, Madagascar’s capital has experienced an accelerating influx of temporary Chinese migrants. The majority of them earn their livelihoods by selling manufactured consumer items imported from China, many of which compete with locally produced goods. This has driven the formation of negative perceptions regarding the impacts of low-cost Chinese imports on Malagasy production. This article fills a knowledge-gap in the literature on China in Africa by exploring local perceptions of temporary Chinese migrants in Madagascar, the growth of small-scale Chinese-owned import and retail businesses in the capital, and their impacts on Malagasy producers, utilizing the country’s blanket and paper industries as case studies. Primarily based on empirical data gathered through extensive fieldwork, it is argued that while in some cases Chinese traders are displacing indigenous producers, in other instances they are enhancing economic opportunities for Malagasy entrepreneurs through their more indirect and fluid impacts resulting from the flow of human capital from China to Madagascar. Keywords : Chinese migration, Madagascar, human capital, perceptions, impacts
Singularity analysis and derivative scale-space

The scale-space representations and wavelet transform theory have provided us with good singularity detection frameworks. Thanks to such methods, image understanding processes have become more and more powerful. Some computer vision tasks also require a knowledge on the nature of detected singularities. We propose, in this paper, to take into account these requirements, and we present a singularity detection method based on fractional calculus arguments. <<ETX>>
Oil and Protein Accumulation in Developing Seeds Is Influenced by the Expression of a Cytosolic Pyrophosphatase in Arabidopsis[C][W][OA]

This study describes a dominant low-seed-oil mutant (lo15571) of Arabidopsis (Arabidopsis thaliana) generated by enhancer tagging. Compositional analysis of developing siliques and mature seeds indicated reduced conversion of photoassimilates to oil. Immunoblot analysis revealed increased levels of At1g01050 protein in developing siliques of lo15571. At1g01050 encodes a soluble, cytosolic pyrophosphatase and is one of five closely related genes that share predicted cytosolic localization and at least 70% amino acid sequence identity. Expression of At1g01050 using a seed-preferred promoter recreated most features of the lo15571 seed phenotype, including low seed oil content and increased levels of transient starch and soluble sugars in developing siliques. Seed-preferred RNA interference-mediated silencing of At1g01050 and At3g53620, a second cytosolic pyrophosphatase gene that shows expression during seed filling, led to a heritable oil increase of 1% to 4%, mostly at the expense of seed storage protein. These results are consistent with a scenario in which the rate of mobilization of sucrose, for precursor supply of seed storage lipid biosynthesis by cytosolic glycolysis, is strongly influenced by the expression of endogenous pyrophosphatase enzymes. This emphasizes the central role of pyrophosphate-dependent reactions supporting cytosolic glycolysis during seed maturation when ATP supply is low, presumably due to hypoxic conditions. This route is the major route providing precursors for seed oil biosynthesis. ATP-dependent reactions at the entry point of glycolysis in the cytosol or plastid cannot fully compensate for the loss of oil content observed in transgenic events with increased expression of cytosolic pyrophosphatase enzyme in the cytosol. These findings shed new light on the dynamic properties of cytosolic pyrophosphate pools in developing seed and their influence on carbon partitioning during seed filling. Finally, our work uniquely demonstrates that genes encoding cytosolic pyrophosphatase enzymes provide novel targets to improve seed composition for plant biotechnology applications.
Peripheral blood flow changes in response to postexercise cold water immersion

This study compared the effect of postexercise water immersion (WI) at different temperatures on common femoral artery blood flow (CFA), muscle (total haemoglobin; tHb) and skin perfusion (cutaneous vascular conductance; CVC), assessed by Doppler ultrasound, near‐infrared spectroscopy (NIRS) and laser Doppler flowmetry, respectively. Given that heat stress may influence the vascular response during cooling, nine men cycled for 25 min at the first ventilatory threshold followed by intermittent 30‐s cycling at 90% peak power until exhaustion at 32·8 ± 0·4°C and 32 ± 5% RH. They then received 5‐min WI at 8·6 ± 0·2°C (WI9), 14·6 ± 0·3°C (WI15), 35·0 ± 0·4°C (WI35) or passive rest (CON) in a randomized, crossover manner. Heart rate (HR), mean arterial pressure (MAP), muscle (Tmu), thigh skin (Tthigh), rectal (Tre) and mean body (Tbody) temperatures were assessed. At 60 min postimmersion, decreases in Tre after WI35 (−0·6 ± 0·3°C) and CON (−0·6 ± 0·3°C) were different from WI15 (−1·0 ± 0·3°C; P<0·05), but not from WI9 (−1·0 ± 0·3°C; P = 0·074–0·092). WI9 and WI15 had reduced Tbody, Tthigh and Tmu compared with WI35 and CON (P <0·05). CFA, tHb and CVC were lower in WI9 and WI15 compared with CON (P<0·05). tHb following WI9 remained lower than CON (P = 0·044) at 30 min postimmersion. CVC correlated with tHb during non‐cooling (WI35 and CON) (r2 = 0·532; P<0·001) and cooling recovery (WI9 and WI15) (r2 = 0·19; P = 0·035). WI9 resulted in prolonged reduction in muscle perfusion. This suggests that CWI below 10°C should not be used for short‐term (i.e. <60 min) recovery after exercise.
A Design Procedure for Optimizing the LLC Resonant Converter as a Wide Output Range Voltage Source

LLC resonant converter is one of the most suitable circuit topologies that have been introduced for designing constant output voltage switched-mode power supplies. In this paper, a design procedure is introduced for using this converter as a wide output range voltage source. Unlike constant output voltage applications which need small converter inductance ratio and narrow switching frequency variations, for wide output range applications, large values of these parameters are needed simultaneously and should be optimized. Instead of minimizing the components stresses, leading to a great value of the inductance ratio, proper choice of the converter parameters resulting in a smaller inductance ratio has been done. Maximum value of the capacitor in parallel with the power MOSFETs drain-sources has been derived to realize the zero voltage switching operation in the converter inductive region. Soft switching is achieved for all power devices under all operating conditions. A prototype of the converter has been tested for different regulated output voltages (35-165 Vdc) under different loads (0-3 Adc) and input voltages (320-370 Vdc) for using an ion implanter arc power supply, with maximum efficiency value of 94.7%. Experimental results confirm the high performance of the wide output range LLC resonant converter even under the worst case conditions.
Integrating Values into Public Service: The Values Statement as Centerpiece

The public administration community needs to focus more attention on how values can be integrated into the structures, processes, and systems of public organizations. In particular, greater emphasis should be placed on the values statement as the central component of a values regime. This article examines the content and format of values statements in four Westminster-style governments, initiatives to make values a pervasive influence in public-service operations, and learning points for other countries. Each government's values statement should capture the essence of public service. Leaders must serve as both exemplary models of values-based behavior and skillful practitioners of the art of values management. A values statement expressing values that are shared at all organizational levels—combined with the dispersal of leadership roles throughout the organization—provides an especially strong foundation for integrating values into public service.
Fluorescence Lifetime Spectroscopy of a pH‐Sensitive Dye Encapsulated in Hydrogel Beads

A pH‐sensing dye, carboxy seminaphthofluorescein‐1 (C‐SNAFL‐1), was immobilized in poly(ethylene glycol) (PEG) microparticles via ester‐amine reaction. Following photopolymerization, the hydrogel particles were then immersed in buffered pH solutions of varying pH with added polystyrene. Measurements of phase shift and amplitude attenuation of the generated and multiply scattered fluorescent light were attained as a function of modulation frequency of the incident excitation light. Upon regressing the measured data to the coupled optical diffusion equations, the average lifetimes of protonated and deprotonated forms of C‐SNAFL‐1 were obtained and compared to the values acquired from conventional fluorescence lifetime spectroscopy in nonscattering media. The results demonstrate the ability to perform analyte sensing with fluorescence lifetime without the confounding effect of fluorophore loading or the use of a “reference” measurement within multiply scattering systems. When extended to the immobilized fluorophore‐enzymatic systems, fluorescence lifetime spectroscopy with multiply scattered light may provide a new ultrasensitive approach for analyte or toxin screening.
Functional Literacy, Heterogeneity and the Returns to Schooling: Multi-Country Evidence

Little is known about which of the skills that make up workers' human capital contribute to higher earnings. Past empirical evidence suggest that most of the return to schooling is generated by effects or correlates unrelated to the skills measured by the available tests. This paper uses the International Adult Literacy and the Adult Literacy and Life Skills surveys to obtain multi-country estimates of the components of the return to schooling. The results reveal considerable heterogeneity and a dichotomy between two groups of countries. For a subgroup of educationally advanced countries, nearly half of the return to schooling can be attributed to labor marker-relevant functional literacy skills associated with schooling, while for a subgroup of less educationally advanced countries, such skills account for just over 20 percent of the return to schooling, while the return to schooling mostly reflects the signaling value of schooling.
SAT02-1: Iterative Frequency and Channel Estimation Coupled with Multiuser Detection in Multibeam Satellite Communications

This paper introduces an iterative multiuser detection scheme, including channel estimation, for the reverse link of (narrowband) multibeam satellite communication systems with convolutional coding. After a derivation of the algorithm on a symbol-asynchronous time-invariant channel, we discuss and evaluate possible adaptations to the more realistic case of frequency offsets affecting user terminals.
Implementation of low-power and high-performance asynchronous dual-rail join using domino logic gates in 16-nm technology

This paper presents a transistor level circuit design for an Asynchronous Dual-Rail Domino Join (ADRDJ) using PTM 16-nm model at 0.7 V power supply. The ADRDJ scheme is a low-power and high-performance weakly indicating functional block. Also, it is reduced the layout congestion due to removing the clock distribution network. Simulation results for a wide sequence of inputs are shown that comparing with the synchronous counterpart, the latency and power consumption improvements are 6% and 51.8%, respectively. Also, the ADRDJ scheme is consumed 46.7% more silicon with respect to synchronous dual-rail domino join (SDRDJ). However, since the clock distribution network is removed, the overall area overhead will be reduced.
