Valuing Diversity: A Group-Value Approach to Understanding the Importance of Organizational Efforts to Support Diversity

Using Leventhal’s rules as well as the group-value model of procedural justice, we first examined how the negative effects of perceived racial discrimination on procedural justice judgments can be attenuated by perceived organizational efforts to support diversity. Secondly, we examine how these effects ultimately impact affective commitment and organizational citizenship behavior. We found that employees who believe some individuals in the workplace are discriminating against them on the basis of race tend to report lower levels of procedural justice from the organization. However, this negative relationship was attenuated when employees perceived that their organization was making efforts to support diversity. Results suggest that individuals’ perceptions of organizational efforts to support diversity can help restore perceptions of procedural justice for employees who experience racial discrimination at work. Improving procedural justice also positively impacts affective commitment and organizational citizenship behavior directed at the organization. Copyright # 2009 John Wiley & Sons, Ltd.

Optimal Planning of Electric-Vehicle Charging Stations in Distribution Systems

With the progressive exhaustion of fossil energy and the enhanced awareness of environmental protection, more attention is being paid to electric vehicles (EVs). Inappropriate siting and sizing of EV charging stations could have negative effects on the development of EVs, the layout of the city traffic network, and the convenience of EVs' drivers, and lead to an increase in network losses and a degradation in voltage profiles at some nodes. Given this background, the optimal sites of EV charging stations are first identified by a two-step screening method with environmental factors and service radius of EV charging stations considered. Then, a mathematical model for the optimal sizing of EV charging stations is developed with the minimization of total cost associated with EV charging stations to be planned as the objective function and solved by a modified primal-dual interior point algorithm (MPDIPA). Finally, simulation results of the IEEE 123-node test feeder have demonstrated that the developed model and method cannot only attain the reasonable planning scheme of EV charging stations, but also reduce the network loss and improve the voltage profile.
Angle Estimation of Simultaneous Orthogonal Rotations from 3D Gyroscope Measurements

A 3D gyroscope provides measurements of angular velocities around its three intrinsic orthogonal axes, enabling angular orientation estimation. Because the measured angular velocities represent simultaneous rotations, it is not appropriate to consider them sequentially. Rotations in general are not commutative, and each possible rotation sequence has a different resulting angular orientation. None of these angular orientations is the correct simultaneous rotation result. However, every angular orientation can be represented by a single rotation. This paper presents an analytic derivation of the axis and angle of the single rotation equivalent to three simultaneous rotations around orthogonal axes when the measured angular velocities or their proportions are approximately constant. Based on the resulting expressions, a vector called the simultaneous orthogonal rotations angle (SORA) is defined, with components equal to the angles of three simultaneous rotations around coordinate system axes. The orientation and magnitude of this vector are equal to the equivalent single rotation axis and angle, respectively. As long as the orientation of the actual rotation axis is constant, given the SORA, the angular orientation of a rigid body can be calculated in a single step, thus making it possible to avoid computing the iterative infinitesimal rotation approximation. The performed test measurements confirm the validity of the SORA concept. SORA is simple and well-suited for use in the real-time calculation of angular orientation based on angular velocity measurements derived using a gyroscope. Moreover, because of its demonstrated simplicity, SORA can also be used in general angular orientation notation.
Applying WebTables in Practice

We started investigating the collection of HTML tables on the Web and developed the WebTables system a few years ago [4]. Since then, our work has been motivated by applying WebTables in a broad set of applications at Google, resulting in several product launches. In this paper, we describe the challenges faced, lessons learned, and new insights that we gained from our efforts. The main challenges we faced in our efforts were (1) identifying tables that are likely to contain high-quality data (as opposed to tables used for navigation, layout, or formatting), and (2) recovering the semantics of these tables or signals that hint at their semantics. The result is a semantically enriched table corpus that we used to develop several services. First, we created a search engine for structured data whose index includes over a hundred million HTML tables. Second, we enabled users of Google Docs (through its Research Panel) to find relevant data tables and to insert such data into their documents as needed. Most recently, we brought WebTables to a much broader audience by using the table corpus to provide richer tabular snippets for fact-seeking web search queries on Google.com.

Economic history and the modern economist

In this book, nine economists and economic historians express their concern for the present state of economics and its development in the future. From a variety of different approaches, these scholars reassert the importance of economic history in the training of economists and urge that this perspective should not be lost in the future.
Clinical, radiographic and immunogenic effects after 1 year of tocilizumab-based treatment strategies in rheumatoid arthritis: the ACT-RAY study

OBJECTIVE
To assess the 1-year efficacy and safety of a regimen of tocilizumab plus methotrexate or placebo, which was augmented by a treat-to-target strategy from week 24.


METHODS
ACT-RAY was a double-blind, 3-year trial. Adults with active rheumatoid arthritis despite methotrexate were randomised to add tocilizumab to ongoing methotrexate (add-on strategy) or to switch to tocilizumab plus placebo (switch strategy). Tocilizumab 8 mg/kg was administered every 4 weeks. Conventional open-label disease-modifying antirheumatic drugs (DMARDs) other than methotrexate were added at week 24 or later in patients with DAS28>3.2.


RESULTS
556 patients were randomised; 85% completed 52 weeks. The proportion of patients receiving open-label DMARDs was comparable in the add-on (29%) and switch (33%) arms. Overall, week 24 results were maintained or further improved at week 52 in both arms. Some endpoints favoured the add-on strategy. Mean changes in Genant-modified Sharp scores were small; more add-on (92.8%) than switch patients (86.1%) had no radiographic progression. At week 52, comparable numbers of patients had antidrug antibodies (ADAs; 1.5% and 2.2% of add-on and switch patients, respectively) and neutralising ADAs (0.7% and 1.8%). Rates of serious adverse events and serious infections per 100 patient-year (PY) were 11.3 and 4.5 in add-on and 16.8 and 5.5 in switch patients. In patients with normal baseline values, alanine aminotransferase elevations >3× upper limit of normal were observed in 11% of add-on and 3% of switch patients.


CONCLUSIONS
Despite a trend favouring the add-on strategy, these data suggest that both tocilizumab add-on and switch strategies led to meaningful clinical and radiographic responses.
MACHINE TRANSLATION The process of translating comprises in its essence the whole secret of human understanding and social communication

The process of translating comprises in its essence the whole secret of human understanding and social communication. This chapter introduces techniques for machine translation (MT), the use of MACHINE TRANSLATION MT computers to automate some or all of the process of translating from one language to another. Translation, in its full generality, is a difficult, fascinating, and intensely human endeavor, as rich as any other area of human creativity. Consider the following passage from the end of Chapter 45 of the 18th-century novel The Story of the Stone, also called Dream of the Red Chamber, by Cao Xue Qin (Cao, 1792), transcribed in the Mandarin dialect: Fig. 24.1 shows the English translation of this passage by David Hawkes, in sentences labeled E 1-E 4. For ease of reading, instead of giving the Chinese, we have shown the English glosses of each Chinese word IN SMALL CAPS. Words in blue are Chinese words not translated into English, or English words not in the Chinese. We have shown alignment lines between words that roughly correspond in the two languages. Consider some of the issues involved in this translation. First, the English and Chinese texts are very different structurally and lexically. The four English sentences (notice the periods in blue) correspond to one long Chinese sentence. The word order of the two texts is very different, as we can see by the many crossed alignment lines in Fig. 24.1. The English has many more words than the Chinese, as we can see by the large number of English words marked in blue. Many of these differences are caused by structural differences between the two languages. For example, because Chinese rarely marks verbal aspect or tense; the English translation has additional words like as, turned to, and had begun, and Hawkes had to decide to translate Chinese tou as penetrated, rather than say was penetrating or had penetrated. Chinese has less articles than English, explaining the large number of blue thes. Chinese also uses far fewer pronouns than English, so Hawkes had to insert she and her in many places into the
What Is Social Software?

The first third (roughly) of the XXth century saw two important developments. One of these was Ramsey's tracing of personal probabilities to an agent's choices. This was a precursor to the work of de Finetti, von Neumann and Morgenstern, and Savage. The other one was Turing's invention of the Turing machine and the formulation of the Church-Turing thesis according to which all computable functions on natural numbers were recursive or Turing computable. Game theory has depended heavily on the first of these developments, since of course von Neumann and Morgenstern can be regarded as the fathers of Game theory. But the other development has received less attention (within Game theory itself). This development led to the design of computers and also to fields like logic of programs, complexity theory and analysis of algorithms. It also resulted in much deeper understanding of algorithms, but only computer algorithms. Social algorithms remain largely unanalyzed except in special subfields like social choice theory or fair division [5]. These fields do not tend to analyze complex social algorithms as is done in computer science. This paper illustrates the different ingredients that make up social software: logical structure, knowledge and incentives.
Sentiment Analysis: Detecting Valence, Emotions, and Other Affectual States from Text

The term sentiment analysis can be used to refer to many different, but related, problems. Most commonly, it is used to refer to the task of automatically determining the valence or polarity of a piece of text, whether it is positive, negative, or neutral. However, more generally, it refers to determining one’s attitude towards a particular target or topic. Here, attitude can mean an evaluative judgment, such as positive or negative, or an emotional or affectual attitude such as frustration, joy, anger, sadness, excitement, and so on. Note that some authors consider feelings to be the general category that includes attitude, emotions, moods, and other affectual states. In this chapter, we use ‘sentiment analysis’ to refer to the task of automatically determining feelings from text, in other words, automatically determining valence, emotions, and other affectual states from text. Osgood, Suci, and Tannenbaum (1957) showed that the three most prominent dimensions of meaning are evaluation (good–bad), potency (strong–weak), and activity (active– passive). Evaluativeness is roughly the same dimension as valence (positive–negative). Russell (1980) developed a circumplex model of affect characterized by two primary dimensions: valence and arousal (degree of reactivity to stimulus). Thus, it is not surprising that large amounts of work in sentiment analysis are focused on determining valence. (See survey articles by Pang and Lee (2008), Liu and Zhang (2012), and Liu (2015).) However, there is some work on automatically detecting arousal (Thelwall, Buckley, Paltoglou, Cai, & Kappas, 2010; Kiritchenko, Zhu, & Mohammad, 2014b; Mohammad, Kiritchenko, & Zhu, 2013a) and growing interest in detecting emotions such as anger, frustration, sadness, and optimism in text (Mohammad, 2012; Bellegarda, 2010; Tokuhisa, Inui, & Matsumoto, 2008; Strapparava & Mihalcea, 2007; John, Boucouvalas, & Xu, 2006; Mihalcea & Liu, 2006; Genereux & Evans, 2006; Ma, Prendinger, & Ishizuka, 2005; Holzman & Pottenger, 2003; Boucouvalas, 2002; Zhe & Boucouvalas, 2002). Further, massive amounts of data emanating from social media have led to significant interest in analyzing blog posts, tweets, instant messages, customer reviews, and Facebook posts for both valence (Kiritchenko et al., 2014b; Kiritchenko, Zhu, Cherry, & Mohammad, 2014a; Mohammad et al., 2013a; Aisopos, Papadakis, Tserpes, & Varvarigou, 2012; Bakliwal, Arora, Madhappan, Kapre, Singh, & Varma, 2012; Agarwal, Xie, Vovsha, Rambow, & Passonneau, 2011; Thelwall, Buckley, & Paltoglou, 2011; Brody & Diakopoulos, 2011; Pak & Paroubek, 2010) and emotions (Hasan, Rundensteiner, & Agu, 2014; Mohammad & Kiritchenko, 2014; Mohammad, Zhu, Kiritchenko, & Martin, 2014; Choudhury, Counts, & Gamon, 2012; Mohammad, 2012a; Wang, Chen, Thirunarayan, & Sheth, 2012; Tumasjan, Sprenger, Sandner, & Welpe, 2010b; Kim, Gilbert, Edwards, &
Evaluating the Cost of Software Quality

There is some confusion about the business value of quality even outside the software development context. On the one hand, there are those who believe that it is economical to maximize quality. This is the “quality is free” perspective espoused by Crosby [7], Juran and Gryna [8], and others. Their key argument is that as the voluntary costs of defect prevention are increased, the involuntary costs of rework decrease by much more than the increase in prevention costs. The net result is lower total costs, and thus quality is free. On the other hand, there are those who believe it is uneconomical to have high levels of quality and assume they must sacrifice quality to achieve other objectives such as reduced development cycles. For example, a study of adoption of the Software Engineering Institute’s Capability Maturity Model (CMM) reports the following quote from a software manager: “I’d rather have it wrong than have it late. We can always fix it later” [11]. Experiences in manufacturing relating to the cost
Tracking speech-presence uncertainty to improve speech enhancement in non-stationary noise environments

Speech enhancement algorithms which are based on estimating the short-time spectral amplitude of the clean speech have better performance when a soft-decision gain modification, depending on the a priori probability of sp eech absence, is used. In reported works a fixed probability, q, is assumed. Since speech is non-stationary and may not be present in every frequency bin when voiced, we propose a method for estimating distinct values of q for different bins which are tracked in time. The estimation is based on a decision-theoretic approach for setting a threshold in each bin followed by short-time averaging. The estimated q's are used to control both the gain and the update of the estimated noise spectrum during speech presence in a modified MMSE log-spectral amplitude estimator. Subjective tests resulted in higher scores than for the IS-127 standard enhancement algorithm, when pre-processing noisy speech for a coding application.
Zygomatic-maxillary buttress reconstruction of midface defects with the osteocutaneous radial forearm free flap.

BACKGROUND
The purpose of this study was to evaluate morbidity, functional, and aesthetic outcomes in midface zygomatic-maxillary buttress reconstruction using the osteocutaneous radial forearm free flap (OCRFFF).


METHODS
A retrospective review of 24 consecutive patients that underwent midface reconstruction using the OCRFFF was performed. All patients had variable extension of maxillectomy defects that requires restoration of the zygomatic-maxillary buttress. After harvest, the OCRFFF was fixed transversely with miniplates connecting the remaining zygoma to the anterior maxilla. The orbital support was given by titanium mesh when needed that was fixed to the radial forearm bone anteriorly and placed on the remaining orbital floor posteriorly. The skin paddle was used for intraoral lining, external skin coverage, or both. The main outcome measures were flap success, donor-site morbidity, orbital, and oral complications. Facial contour, speech understandability, swallowing, oronasal separation, and socialization were also analyzed.


RESULTS
There were 6 women and 18 men, with an average age of 66 years old (range, 34-87). The resulting defects after maxillectomy were (according to the Cordeiro classification; Disa et al, Ann Plast Surg 2001;47:612-619; Santamaria and Cordeiro, J Surg Oncol 2006;94:522-531): type I (8.3%), type II (33.3%), type III (45.8%), and type IV (12.5%). There were no flap losses. Donor-site complications included partial loss of the split thickness skin graft (25%) and 1 radial bone fracture. The most significant recipient-site complications were severe ectropion (24%), dystopia (8%), and oronasal fistula (12%). All the complications occurred in patients with defects that required orbital floor reconstruction and/or cheek skin coverage. The average follow-up was 11.5 months, and over 80% of the patients had adequate swallowing, speech, and reincorporation to normal daily activities.


CONCLUSIONS
The OCRFFF is an excellent alternative for midface reconstruction of the zygomatic-maxillary buttress. Complications were more common in patients who underwent resection of the orbital rim and floor (type III and IV defects) or external cheek skin.
Attitudes of People in the UK with HIV Who Are Antiretroviral (ART) Naïve to Starting ART at High CD4 Counts for Potential Health Benefit or to Prevent HIV Transmission

OBJECTIVE
To assess if a strategy of early ART to prevent HIV transmission is acceptable to ART naïve people with HIV with high CD4 counts.


DESIGN
ASTRA is a UK multicentre, cross sectional study of 3258 HIV outpatients in 2011/12. A self-completed questionnaire collected sociodemographic, behavioral and health data, and attitudes to ART; CD4 count was recorded from clinical records.


METHODS
ART naïve participants with CD4 ≥350 cells/µL (n = 281) were asked to agree/disagree/undecided with the statements (i) I would want to start treatment now if this would slightly reduce my risk of getting a serious illness, and (ii) I would want to start treatment now if this would make me less infectious to a sexual partner, even if there was no benefit to my own health.


RESULTS
Participants were 85% MSM, 76% white, 11% women. Of 281 participants, 49.5% and 45.2% agreed they would start ART for reasons (i) and (ii) respectively; 62.6% agreed with either (i) or (ii); 12.5% agreed with neither; 24.9% were uncertain. Factors independently associated (p<0.1) with agreement to (i) were: lower CD4, more recent HIV diagnosis, physical symptoms, not being depressed, greater financial hardship, and with agreement to (ii) were: being heterosexual, more recent HIV diagnosis, being sexually active.


CONCLUSIONS
A strategy of starting ART at high CD4 counts is likely to be acceptable to the majority of HIV-diagnosed individuals. Almost half with CD4 >350 would start ART to reduce infectiousness, even if treatment did not benefit their own health. However a significant minority would not like to start ART either for modest health benefit or to reduce infectivity. Any change in approach to ART initiation must take account of individual preferences. Transmission models of potential benefit of early ART should consider that ART uptake may be lower than that seen with low CD4 counts.
Green Cognitive Mobile Networks With Small Cells for Multimedia Communications in the Smart Grid Environment

High-data-rate mobile multimedia applications can greatly increase energy consumption, leading to an emerging trend of addressing the “energy efficiency” aspect of mobile networks. Cognitive mobile networks with small cells are important techniques for meeting the high-data-rate requirements and improving the energy efficiency of mobile multimedia communications. However, most existing works do not consider the power grid, which provides electricity to mobile networks. Currently, the power grid is experiencing a significant shift from the traditional grid to the smart grid. In the smart grid environment, only considering energy efficiency may not be sufficient since the dynamics of the smart grid will have significant impacts on mobile networks. In this paper, we study green cognitive mobile networks with small cells in the smart grid environment. Unlike most existing studies on cognitive networks, where only the radio spectrum is sensed, our cognitive networks sense not only the radio spectrum environment but also the smart grid environment, based on which power allocation and interference management for multimedia communications are performed. We formulate the problems of electricity price decision, energy-efficient power allocation, and interference management as a three-stage Stackelberg game. A homogeneous Bertrand game with asymmetric costs is used to model price decisions made by the electricity retailers. A backward induction method is used to analyze the proposed Stackelberg game. Simulation results show that our proposed scheme can significantly reduce operational expenditure and CO2 emissions in cognitive mobile networks with small cells for multimedia communications.
