Computer-related technostress in China

Technostress has been defined as any negative effect on human attitudes, thoughts, behavior, and psychology that directly or indirectly results from technology [8]. With the recent widespread application of IT and the Internet throughout China, technostress has become a serious issue for both users and IT professionals due to its potential effect on users' mental health and on-the-job productivity. Chinese employees are surrounded, often overwhelmed, by modern technology. The top 100 largest Chinese enterprises, accounting for 25% of China's GDP, are investing heavily ($10--$15 billion annually) in new IT applications, including enterprise resource planning systems. A 2002 report by the Chinese Ministry of Information Industry stated that there are 380 million mobile phone subscribers in China, making the country the world's largest mobile phone market. And a survey conducted in 2004 by the China Internet Network Information Center found that 87 million Chinese frequently accessed the Internet in 2004, an increase of 19 million, or 27.9%, over 2003.
Second Language Learning in an Immersion Programme: Factors Influencing Acquisition and Retention

This study investigated the relations of a series of attitude, motivation and aptitude variables to the acquisition and retention of French language skills. Subjects were drawn from a sample of 105 students registered in an intensive French language summer training programme in Trois-Pistoles, Quebec, who completed a series of tests at the beginning and end of the course. A factor analysis of data from the 89 students with complete data identified four factors, French Achievement, Integrative Motive, Self-confidence with French, and SelfPerception of French Competence. These results suggested that the roles played by language aptitude and attitudinal/motivational variables differed somewhat, and reflected the socio-cultural conditions under which language learning took place. Investigation of language loss suggested that language use and attitudinal/ motivational characteristics were major factors involved in the retention of second language skills in the period following intensive training.
Chapter XXX Holland's Vocational Theory and Personality Traits of Information Technology Professionals

Drawing on Holland’s (1985, 1996) vocational theory and based on a sample of 9,011 IT professionals, two research questions were investigated. On what personality traits do IT professionals differ from other occupations and which of these are also related to their career satisfaction? Five traits met both these criteria—Emotional Resilience, Openness, Tough-Mindedness, and Customer Service—for which IT professionals had higher scores, and conscientiousness, for which they had lower scores. IT career satisfaction was also positively related to E xtraversion, Agreeableness/Teamwork, Assertiveness, Optimism, Tough-Mindedness, Work Drive, and Visionary Style. Results are discussed in terms of the fit of these traits with IT work and the value of these insights for personnel-management functions like selection, training, professional development, and career planning.
Miss data reconstruction in remote sensing images with a double weighted tensor low rank model

Missing data reconstruction (e.g., dead pixel repair and cloud removing) in remote sensing images is a very important problem for the subsequent image analysis. It is well-known that missing data reconstruction is an ill-posed problem. In remote sensing images, there is a strong correlation in spectral frequencies or in temporal frames, and also there are a lot of self-similarity patterns in spatial domain. We can make use of these properties to derive low rank matrices according to their spectral, temporal and spatial dimensions. In this paper, we propose a tensor completion model based on these low rank matrices to deal with missing data reconstruction problem. We also present a weighting method for spectral, temporal and spatial dimensions and for their distribution of singular values. Our experimental results demonstrate that the weighting method can recover remote images very well. In particular, we show the effectiveness of the proposed method for both simulated and real data sets, and the performance of the proposed in terms of visual and quantitative measures is better than those of the other testing methods.
On the role of social factors in the loss of phonemic distinctions1

The article tests the generalisation of the curvilinear hypothesis and the tendency of females to lead linguistic change in vocalic mergers on the basis of two mergers currently in progress in Charleston, South Carolina: the low-back merger and the pin–pen merger. It is based on sociolinguistic interviews with 100 informants, aged 8–90, covering the socioeconomic spectrum of the city. The speech of 90 of the informants is analysed acoustically; it is supplemented with minimal-pair tests and word list reading. F1/F2 measurements and minimal-pair test results are subjected to a series of multiple linear regression analyses, with social class, gender, age and style as independent variables. While the low-back merger is a change from below showing a female lead and a curvilinear effect of social class, the pin–pen merger shows a decreasing monotonic relationship with social class and no female advantage. The difference is argued to be due to the two mergers being at different levels of social awareness.

Impact of time to cooling initiation and time to target temperature in patients treated with hypothermia after cardiac arrest

Purpose: Little is known about the role of time to initiation of therapeutic hypothermia and time to target temperature (TTT) in the prognosis of patients resuscitated from cardiac arrest. Methods: A retrospective analysis was performed in 145 survivors of cardiac arrest who underwent therapeutic hypothermia between January 2003 and January 2013. The objective was to identify predictors of survival free from significant neurological sequelae (Cerebral Performance Categories Scale (CPC): >2) six months after cardiac arrest. We evaluated the effect of faster and earlier cooling. Results: Overall survival at six months was 42.1% (61 patients); 59 of these were considered to have a good neurological status (CPC≤2), and in whom therapeutic hypothermia was initiated earlier (87±17 min vs. 111±14 min; p=0.042), and the target temperature was reached at an earlier time (TTT: 316 ± 30 min vs. 365 ± 27 min; p=0.017). Multivariate analysis selected longer duration of cardiac arrest (odds ratio (OR) =1.06 per min), a non-shockable initial rhythm (OR=13.8), severe acidosis (OR=0.009 per 0.01 unit), older age (OR=1.04 per year) and longer TTT (OR=1.005 per min) as associated with poor prognosis. Conclusion: The most important prognostic factors for death or lack of neurological recovery in patients with cardiac arrest treated with therapeutic hypothermia are initial-rhythm, time from cardiac arrest to return of spontaneous circulation and arterial-pH at admission. Although the speed of cooling initiation and the time to reach target temperature may play a role, its influence on prognosis seems to be less important.
Testing maternal depression and attachment style as moderators of early head start's effects on parenting

This study examined maternal depression, attachment avoidance, and attachment anxiety as moderators of Early Head Start's effects on four parenting outcomes assessed at age three. Participants (N = 947) were drawn from six sites of the Early Head Start National Research and Evaluation Project, a multi-site randomized trial. Findings suggest more positive program effects for mothers with less initial attachment avoidance or attachment anxiety. First, baseline attachment avoidance moderated Early Head Start program effects on observed maternal supportiveness, such that program mothers with lower baseline attachment avoidance were rated as more supportive of their three-year-olds than program mothers with higher baseline attachment avoidance. Second, program effects on spanking varied depending on mothers' baseline attachment anxiety.
Case Report of an Endovascular Repair of a Residual Type A Dissection Using a Not CE Not FDA-Approved Najuta Thoracic Stent Graft System

AbstractThis report describes an endovascular repair of a residual type A dissection using a medical device that is not marked by european conformity (CE) or Food and Drug Administration (FDA). The patient underwent ascending aortic surgery for acute type A dissection. The 2-year angio–computed tomography demonstrated patency of the residual false lumen with evolution into a 6 cm aneurysm, the extension of the dissection from the aortic arch to the aortic bifurcation with thrombosis of the right common iliac artery. There was no CE- or FDA-marked medical device indicated for this case or any other acceptable therapeutic alternative.We used the Najuta thoracic stent graft and successfully handled the pathology in a multiple-phase treatment.Technology is evolving with specific grafts for the ascending and fenestrated grafts for the aortic arch. In this single case the Najuta endograft, in spite of the periprocedural problems, was a valid therapeutic option.
Evaluation of Competing Stimuli within a DRO Contingency

Recent research has shown that preference assessments effectively identify stimuli that produce high levels of interaction relative to low levels of destructive behavior. In general, these stimuli identified through these means have been shown to reduce automatically-reinforced and socially-mediated destructive behavior when incorporated into noncontingent reinforcement treatment programs. However, the effects of high preference stimuli in other reinforcement-based procedures remain unclear. In this preliminary investigation, we evaluated a high preference stimulus in a DRO contingency without an extinction component. The stimulus reduced destructive behavior even when reinforcement was delayed for 60 s in the DRO. Results are discussed in terms of using alternative stimuli to reduce socially-mediated destructive behavior.
Hidden Markov Model Based Part of Speech Tagger for Sinhala Language

In this paper we present a fundamental lexical semantics of Sinhala language and a Hidden Markov Model (HMM) based Part of Speech (POS) Tagger for Sinhala language. In any Natural Language processing task, Part of Speech is a very vital topic, which involves analysing of the construction, behaviour and the dynamics of the language, which the knowledge could utilized in computational linguistics analysis and automation applications. Though Sinhala is a morphologically rich and agglutinative language, in which words are inflected with various grammatical features, tagging is very essential for further analysis of the language. Our research is based on statistical based approach, in which the tagging process is done by computing the tag sequence probability and the word-likelihood probability from the given corpus, where the linguistic knowledge is automatically extracted from the annotated corpus. The current tagger could reach more than 90% of accuracy for known words.
Lymphocyte isoforms of mouse p50 LSP1, which are phosphorylated in mitogen-activated T cells, are formed through alternative splicing and phosphorylation.

p50 is phosphorylated in mitogen-stimulated T cells, and translocated from the membrane to the cytosol after activation of protein kinase C. Sequence analysis of p50 revealed that it is identical with LSP1, a putative calcium-binding and actin-binding protein. lymphocyte form of p50 exhibits heterogeneity in the apparent molecular mass on SDS-PAGE, 50 and 52 kDa (pp50 and pp52), and each isoform exhibits heterogeneity in the isoelectric point, when examined by two-dimensional PAGE. When the two molecular mass variants of p50 were dephosphorylated with alkaline phosphatase, both isoforms showed the same apparent molecular mass of 50 kDa on SDS-PAGE, but could be distinguished by their distinct isoelectric points. Dephosphorylated pp50 (p50a) has an acidic pI compared with dephosphorylated pp52 (p50b). Comparison of the peptide maps of purified p50a and p50b on HPLC revealed that the difference was limited to one peptide peak. NH2-terminal sequence and mass spectrometric analyses of these peptides showed that the peptides derived from p50a and p50b had the same NH2-terminal amino acid sequence up to eight residues, but had distinct molecular masses, 5,533.4 and 6,318.6 Da, respectively. These data suggested that pp52 (p50b) is the product of the previously cloned cDNA and the reduction in the molecular mass of the p50a-derived peptide could be explained by deletion of six amino acid residues, EHLIRH or HLIRHQ.

Sharing, Caring, and Surveilling: An Actor-Partner Interdependence Model Examination of Facebook Relational Maintenance Strategies

Abstract Relational maintenance is connected to high quality friendships. Friendship maintenance behaviors may occur online via social networking sites. This study utilized an Actor-Partner Interdependence Model to examine how Facebook maintenance and surveillance affect friendship quality. Bryant and Marmo's (2012) Facebook maintenance scale was evaluated, revealing two factors: sharing and caring. Facebook surveillance was also measured. For friendship satisfaction and liking, significant positive actor and partner effects emerged for caring; significant negative actor, partner, and interaction effects emerged for sharing; and significant positive actor effects emerged for surveillance. For friendship closeness, significant positive actor effects emerged for caring and surveillance.
[Effects of volume-controlled ventilation and pressure-controlled volume- guaranteed mode during one-lung ventilation on circulation, pulmonary function and lung injury].

OBJECTIVE To compare the effects of volume-controlled ventilation (VCV) and pressure-controlled volume-guaranteed (PCV-VG) mode during one-lung ventilation (OLV) on circulation, pulmonary function and lung injury. METHODS 2012 February to 2013 March in Ningbo No2. Hospital cardiothoracic surgery, 30 patients aged 52 to 76 years (ASA grade II-III) undergoing elective thoracoscopic lobectomy were randomly divided into VCV group and PCV-VG group, with 15 cases in each group. After anesthesia induction and endotracheal intubation, endobronchial blocker was inserted to start OLV. Heart rate (HR), mean arterial pressure (MAP), measured tidal volume (TV), peak airway pressure (Ppeak), airway resistance (Raw), chest compliance (Cdyn) and the end-tidal carbon dioxide pressure (PetCO(2)) were recorded at the time point of 15 minutes after turning to the lateral position, 15 minutes and 60 minutes after OLV, and 15 minutes after the resumption of two lung ventilation. In the meanwhile, arterial blood gas analysis was conducted to measure indicators of pH, oxygen tension (PaO(2)) and carbon dioxide partial pressure (PaCO(2)). Blood was drawn before induction, 1 hour after OLV and 1 hour after the end of surgery, and the concentration of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS HR, MAP, TV, PetCO(2), pH and PaCO(2) in two groups at the time point of 15 minutes after turning to the lateral position, 15 minutes and 60 minutes after OLV, and 15 minutes after the resumption of two lung ventilation showed no significant difference (P > 0.05). At the point of 15 minutes after turning to the lateral position and 15 minutes after two lung ventilation, Ppeak and Cdyn of two groups were significantly different (P < 0.05) (Ppeak:16 ± 3 cmH(2)O, 16 ± 3 cmH(2)O for VCV group and 14 ± 2 cmH(2)O, 14 ± 2 cmH(2)O for PCV-VG group; Cdyn: 43.5 ± 5.9 ml/cmH(2)O, 43.8 ± 6.7 ml/cmH2O for VCV group and 49.7 ± 7.1 ml/cmH(2)O, 53.3 ± 9.6 ml/cmH(2)O for PCV-VG group). Compared with VCV group, PCV-VG group showed a lower Ppeak 15 minutes and 60 minutes after OLV [ (17 ± 2 cmH(2)O) vs (22 ± 4 cmH(2)O) and (18 ± 4 cmH(2)O) vs( 23 ± 3 cmH(2)O) with a higher Cdyn at the same point (38.6 ± 6.3 ml/cmH(2)O) vs (29.6 ± 3.2 ml/cmH(2)O) and 37.3 ± 6.0 ml/cmH(2)O) vs (30.3 ± 3.8 ml/cmH(2)O)] (P < 0.01). Compared with VCV group,IL-6 and TNF-α of PCV-VG group 1 hour after OLV and 1 hour after the end of surgery were significantly lower (P < 0.01) (IL-6: 52.32 ± 3.59 vs 62.65 ± 4.17 pg/ml and 63.57 ± 4.98 vs 82.38 ± 4.10 pg/ml; TNF-α: 3.23 ± 0.27 vs 4.19 ± 0.38 pg/ml and 4.01 ± 0.28 vs. 5.49 ± 0.31 pg/ml). CONCLUSION During one-lung ventilation in thoracoscopic lobectomy, PCV-VG mode has a competitive advantage over VCV mode in terms of pulmonary function and lung protection.
Novel Relevance Feedback Approach to Content-Based Image Retrieval

In content-based image retrieval systems, relevance feedback is an important way to narrow the gap between low-level features and high-level conception. Relevant images were often considered in traditional relevant feedback. But irrelevant images weren't considered. The method of moving query vector and method of updating weight factor are only separately used in content-based image retrieval. A new approach is proposed by combining moving query vector with updating weight and the influence of both relevant and irrelevant images are considered for image retrieval. The results demonstrate that retrieval performance is obviously improved. It is positive meaning for the development of relevance feedback.
An exploration of the relationship between readiness for change and organizational trust in Turkish public schools

Readiness for change is one of the constructs that fosters positive behaviours, attitudes and thinking towards new adjustments on the part of employees. As one of the internal context variables, trust acts as a catalyst for supportive behaviours in times of change and uncertainty by reducing change related resistance and stress. Based on this understanding, this study explores the predictive value of organizational trust for cognitive, emotional and intentional readiness for change among a group of primary and secondary school teachers in Turkey. The data from 603 public school teachers were collected using the Omnibus T-Scale and Readiness for Change-Cognitive Emotional Intentional Scale. Taking each dimension of readiness for change as a criterion variable, three sets of predictors were defined for three separate hierarchical regression analyses. The results provided empirical evidence concerning the relationship between intentional, emotional and cognitive readiness for change and perceived faculty trust in colleagues and in the principal after statistically controlling for the school level and teacher demographics at primary and secondary level public schools. The results were interpreted within the scope of the current literature as well as structural and functional characteristics of Turkish education system.
The S3 State of the Oxygen-Evolving Complex: Overview of Spectroscopy and XFEL Crystallography with a Critical Evaluation of Early-Onset Models for O–O Bond Formation

The catalytic cycle of the oxygen-evolving complex (OEC) of photosystem II (PSII) comprises five intermediate states Si (i = 0–4), from the most reduced S0 state to the most oxidized S4, which spontaneously evolves dioxygen. The precise geometric and electronic structure of the Si states, and hence the mechanism of O–O bond formation in the OEC, remain under investigation, particularly for the final steps of the catalytic cycle. Recent advances in protein crystallography based on X-ray free-electron lasers (XFELs) have produced new structural models for the S3 state, which indicate that two of the oxygen atoms of the inorganic Mn4CaO6 core of the OEC are in very close proximity. This has been interpreted as possible evidence for “early-onset” O–O bond formation in the S3 state, as opposed to the more widely accepted view that the O–O bond is formed in the final state of the cycle, S4. Peroxo or superoxo formation in S3 has received partial support from computational studies. Here, a brief overview is provided of spectroscopic information, recent crystallographic results, and computational models for the S3 state. Emphasis is placed on computational S3 models that involve O–O formation, which are discussed with respect to their agreement with structural information, experimental evidence from various spectroscopic studies, and substrate exchange kinetics. Despite seemingly better agreement with some of the available crystallographic interpretations for the S3 state, models that implicate early-onset O–O bond formation are hard to reconcile with the complete line of experimental evidence, especially with X-ray absorption, X-ray emission, and magnetic resonance spectroscopic observations. Specifically with respect to quantum chemical studies, the inconclusive energetics for the possible isoforms of S3 is an acute problem that is probably beyond the capabilities of standard density functional theory.
Optimal Operation and Services Scheduling for an Electric Vehicle Battery Swapping Station

For a successful rollout of electric vehicles (EVs), it is required to establish an adequate charging infrastructure. The adequate access to such infrastructure would help to mitigate concerns associated with limited EV range and long charging times. Battery swapping stations are poised as effective means of eliminating the long waiting times associated with charging the EV batteries. These stations are mediators between the power system and their customers. In order to successfully deploy this type of stations, a business and operating model is required, that will allow it to generate profits while offering a fast and reliable alternative to charging batteries. This paper proposes an optimization framework for the operating model of battery swapping stations. The proposed model considers the day-ahead scheduling process. Battery demand uncertainty is modeled using inventory robust optimization, while multi-band robust optimization is employed to model electricity price uncertainty. The results show the viability of the proposed model as a business case, as well as the effectiveness of the model to provide the required service.
Top-k spatial keyword queries on road networks

With the popularization of GPS-enabled devices there is an increasing interest for location-based queries. In this context, one interesting problem is processing top-k spatial keyword queries. Given a set of objects with a textual description (e.g., menu of a restaurant), a query location (latitude and longitude), and a set of query keywords, a top-k spatial keyword query returns the k best objects ranked in terms of both distance to the query location and textual relevance to the query keywords. So far, the research on this problem has assumed Euclidean space. In order to process such queries efficiently, spatio-textual indexes combining R-trees and inverted files are employed. However, for most real applications, the distance between the objects and query location is constrained by a road network (shortest path) and cannot be computed efficiently using R-trees. In this paper, we address, for the first time, the challenging problem of processing top-k spatial keyword queries on road networks where the distance between the query location and the spatial object is the shortest path. We formalize the new query type, and present novel indexing structures and algorithms that are able to process such queries efficiently. Finally, we perform an experimental evaluation that shows the efficiency of our approach.
