PurposeThe authors propose and test these boundary conditions to the relationship between voluntary collective turnover and unit performance: job and organizational tenure and the time clustering of turnover.Design/methodology/approachThe authors analyze longitudinal data obtained from 231 units of an international clothing retailer in Spain assessed during 36 months.FindingsThe authors show that when the remaining workforce has moderate, but not low or high, levels of job and organizational tenure, the negative effect of quits on performance is buffered. Furthermore, their results show that time-clustered voluntary turnover patterns have stronger negative effects on unit performance than turnover patterns spread over time.Originality/valueThe authors extend the collective turnover literature addressing two qualitative properties of the content of voluntary turnover, the experience of the workers that remain in the unit after the turnover events happen and how these events are clustered/dispersed over time.

Pride is a self-conscious emotion evoked when individuals perceive themselves attaining an outcome that is congruent with their goals and being responsible for achieving a socially valued outcome. The experience of pride can influence one’s own behaviors but the accompanying expressions can also elicit behavioral changes in observers. Although pride is a positive emotion and provides individuals with psychological rewards and pleasant feelings, accumulated empirical findings show a broad range of consequences in response to both the experience and expression of pride in organizations. In attempts to explain the various outcomes, pride researchers have conceptualized the construct in different ways. Some researchers examine pride as a unified emotion that arises from the attainment of positive outcomes; others adopt a multifaceted view to explain its divergent consequences. The multifaceted view suggests that pride can be authentic or hubristic depending on whether the achievement is assumed to arise from one’s efforts or abilities, and promotive or preventive depending on whether the achievement is assumed to result from promotion-related eagerness or prevention-related vigilance. Pride may also be differentiated into specific facets based on whether it is elicited by the achievement of performance or moral standards. Furthermore, as the individual self is embedded in social contexts, pride can arise from group belongingness. Thus, the conceptualization of pride can extend beyond the individual level to cover group and organizational pride. This article concludes that pride is an important source of motivation for both individuals who experience it and those who express it in organizations. Yet, what outcomes or behaviors result depends crucially on the source of pride because pride leads individuals to repeat behaviors attributed as the original cause of the positive feeling. Although pride is commonly engendered by achievements and socially desirable outcomes, it can also arise from immoral behaviors when those behaviors are assumed to benefit the organization. The outcomes of pride experience and expression are also contingent on individual and contextual boundary conditions.

Past work investigating the lingual articulation of devoiced vowels in Tokyo Japanese has revealed optional but categorical deletion. Some devoiced vowels retained a full lingual target, just like their voiced counterparts, whereas others showed trajectories that are best modelled as targetless, i.e., linear interpolation between the surrounding vowels. The current study explored the hypothesis that this probabilistic deletion is modulated by the identity of the surrounding consonants. A new EMA experiment with an extended stimulus set replicates the core finding of Shaw, Jason & Shigeto Kawahara. 2018b. The lingual gesture of devoiced [u] in Japanese. Journal of Phonetics 66. 100–119. DOI:https://doi.org/10.1016/j.wocn.2017.09.007 that Japanese devoiced [u] sometimes lacks a tongue body raising gesture. The current results moreover show that surrounding consonants do indeed affect the probability of tongue dorsum targetlessness. We found that deletion of devoiced vowels is affected by the place of articulation of the preceding consonant; deletion is more likely following a coronal fricative than a labial fricative. Additionally, we found that the manner combination of the flanking consonants, fricative–fricative versus fricative–stop, also has an effect, at least for some speakers; however, unlike the effect of C1 place, the direction of the manner combination effect varies across speakers with some deleting more often in fricative–stop environments and others more often in fricative–fricative environments.

Using the framework of role balance theory, the authors take a cross-national view of an employee’s engagement in the work and nonwork domains of life. Employing the World Values Survey (WVS) with a sample of 21,270 married employees from 53 nations, we find cross-national variations in the relationship of employees’ degree of work and nonwork domain engagements with their subjective health and satisfaction with life. To explore the impact of the national focus on motivation for economic productivity and innovation, we used a country’s global competitiveness index (GCI), predicting that a nation’s GCI would moderate the relationship of an employee’s work and nonwork domain engagements with both subjective health and life satisfaction. Overall, the results suggest that work–nonwork balance leads to better subjective health and higher life satisfaction only for married employees living in nations high in GCI; for married employees living in countries low in GCI, higher subjective health and life satisfaction resulted for those more highly engaged in nonwork life domains. Theoretical and methodological contributions are discussed, along with implications for future research on national culture concerning work and its impact on employed persons.

The Journal of Management editorial team challenged us to consider how the COVID-19 pandemic impacted and altered the employer–employee relationship. In this guest editorial, we take stock of the pandemic-related lessons learned for human resources research and practice. We highlight three insights that many organizations made as the result of pandemic-related changes and describe how these lessons are likely to alter the employee–employer landscape for the foreseeable future. The lessons are (a) understanding that organizational communication practices should be authentic, continuous, and two-way in nature; (b) accepting that the virtual workforce brings unique challenges that do not yet have solutions; and (c) recognizing that success for stakeholders beyond just investors will require continual attention and intention. We also highlight needs and opportunities for future research that will inform theory and practice and lead to the betterment of organizations and society.

The relationship between syntactic structure and prosodic structure has received increased theoretical attention in recent years. Richards (2010) proposes that Japanese allows wh-elements to stay in situ because of a certain aspect of its prosodic system. Specifically, in contrast to some other languages like English, Japanese can prosodically group wh-elements together with their licensers. This prosodic grouping is phonetically signaled by eradication or reduction of the lexical pitch accents of intervening words. In this theory, a question still remains as to whether each syntactic derivation is checked against its phonetic realization, or what allows Japanese wh-elements to stay in situ is more abstract phonological prosodic structure, whose phonetic manifestations can potentially be variable. This paper reports an experiment which addressed this question, by testing whether there is eradication or reduction of lexical pitch accents based on the detailed analysis of F0 contours. Our analysis makes use of a computational toolkit that allows us to assess the presence of tonal targets on a token-by-token basis. The results demonstrate that almost all speakers produce some wh-sentences which show reduction or eradication of the lexical pitch accents, as well as some that do not. Those tokens that show reduction or eradication directly support the prediction of Richards’ (2010) theory. The variability observed in the results suggests that the property of Japanese that allows their wh-elements to stay in situ must be abstract, phonological prosodic structure, whose phonetic realizations can vary within and across speakers. We discuss several possible mechanisms through which such phonetic variation can arise.

Vowel contrasts tend to be perceived independently of pitch modulation, but it is not known whether pitch can be perceived independently of vowel quality. This issue was investigated in the context of a lexical tone language, Mandarin Chinese, using a printed word version of the visual world paradigm. Eye movements to four printed words were tracked while listeners heard target words that differed from competitors only in tone (test condition) or also in onset consonant and vowel (control condition). Results showed that the timecourse of tone recognition is influenced by vowel quality for high, low, and rising tones. For these tones, the time for the eyes to converge on the target word in the test condition (relative to control) depended on the vowel with which the tone was coarticulated with /a/ and /i/ supporting faster recognition of high, low, and rising tones than /u/. These patterns are consistent with the hypothesis that tone-conditioned variation in the articulation of /a/ and /i/ facilitates rapid recognition of tones. The one exception to this general pattern-no effect of vowel quality on falling tone perception-may be due to fortuitous amplification of the harmonics relevant for pitch perception in this context.

Management scholars have examined various kinds of workplace mistreatment. These investigations and empirical summaries of the literature show that personal experience of mistreatment at work creates a variety of deleterious problems such as more negative job attitudes, lower performance, and poorer health. The bulk of the literature assumes that the key cause-effect relationship resides at the individual level. However, individuals do not experience mistreatment in a vacuum, but rather in a complex social environment that shapes interpretations of, and reactions to, individual mistreatment. In this integrative review, we depart from prior reviews that focus primarily on personal experiences of mistreatment and instead evaluate the literature on mistreatment in the context of others’ negative experiences. Analyzing 64 empirical articles on own and others’ mistreatment at work, we identify six key theoretical perspectives concerning how others’ experiences shape individual reactions to mistreatment. We then develop a sensemaking and social information processing framework for understanding mistreatment in context. We conclude the article by discussing theoretical and methodological recommendations for future research.

Every field of surgery has seen an explosion of new technologies aimed at improving surgical technique and reducing complications. The use of near-infrared (NIR) fluorescence to assess perfusion has been described in several surgical disciplines. NIR provides the surgeon with real-time perfusion assessment of a target organ or anastomosis and can be invaluable in aiding decision-making during the index operation. In the following article we discuss the use of fluorescence-guided perfusion assessment during colonic interposition for esophageal replacement. To our knowledge this is the first description of the use of fluorescence-guided perfusion assessment during colonic interposition.

We review research on the organizational causes (how do organizations contribute?) and consequences (how are organizations affected?) of economic inequality. Our review of 151 conceptual and empiri...

Few topics have received as much recent attention from researchers across disciplines, practitioners, policymakers, and popular media as “big data”. Yet, from our experiences on the Academy of Management Journal editorial team, we believe a great deal of ambiguity and even confusion still prevails around key questions such as: What does big data encompass? Does big data mean the end of theory? In what ways does big data research differ from conventional scientific methods of inquiry in management research? What does it take to publish a big data study in management journals?

Research Summary An initial public offering (IPO) ushers in many changes to the organization's boards of directors, including the installation of a formal and comprehensive board leadership structure. This paper shows that higher board undervaluation, that is, the average degree to which directors' qualifications based on normatively accepted criteria for board leadership are not duly reflected in their appointments to the board chair and committee chair positions, is associated with higher director turnover, and with lower qualifications among new directors in the subsequent years. Further, the effect of board undervaluation on firm performance is mediated both by director turnover and new directors' qualifications. But these two mediators operate as opposite forces on performance—director turnover is associated with lower firm performance, but counter‐intuitively lower new‐director‐qualifications are associated with higher firm performance. Managerial Summary How should a privately‐held entrepreneurial firm design its board leadership structure at IPO? What are the implications for board evolution and even firm performance? We find that higher board undervaluation, that is, the average degree to which directors' qualifications based on normatively accepted criteria for board leadership are not duly reflected in their appointments to the board chair and committee chair positions, is associated with higher director turnover, and with lower qualifications among new directors in the subsequent years. These two evolutionary paths act in opposite ways on performance—director turnover lowers firm performance, but lower new‐director‐qualifications improve firm performance. This has important implications for boards, investors, and stock exchange guidelines on board leadership structure.

In Tokyo Japanese, high vowels /i/ and /u/ are frequently devoiced when they are surrounded by voiceless obstruents. Controversy remains over whether vowel gestures in devoiced vowels are retained or instead deleted. Both static (Iwasaki et al., 2020) and dynamic (Iwasaki et al., 2022) ultrasound data have indicated that vowel-specific lingual gestures can persist even when vowels are devoiced. This study focuses on the lip articulation of devoiced vowels by examining lateral lip aperture, where lower values index a greater degree of the rounding of vowels. Native speakers of Tokyo Japanese produced nonce word pairs with the form of /C1VC2V2toko/. V1 was either /i/ or /u/. C1 and C2 were either voiced or voiceless, which determined the voicing of V1. Lateral lip aperture during the first mora was calculated by identifying facial landmarks using OpenFace 2.0 (Baltrusaitis et al., 2018), and compared across vowel quality (/i/ vs./u/) and vowel voicing (devoiced vs. voiced). Preliminary results show that lateral lip aperture is larger for /i/ than for /u/ in both devoiced and voiced environments, indicating that these vowels maintain their labial specifications even when devoiced, providing additional evidence that devoiced vowels can retain their articulatory gestures.

Explained pay dispersion theory (Shaw, Gupta, & Delery, 2002) contends that the consequences of pay dispersion depend on two critical contingencies: (1) the presence of legitimate or normatively acceptable dispersion-creating practices, and the (2) identifiability of individual contributions. In this chapter, the first 20 years of empirical evidence and theoretical offshoots of this theory are reviewed. Other recent studies on the outcomes of horizontal and vertical pay dispersion are also evaluated. The review concludes with an evaluative summary of the literature and the identification of several potential fruitful areas for future research.

This study tests whether Australian English (AusE) and European Spanish (ES) listeners differ in their categorisation and discrimination of Brazilian Portuguese (BP) vowels. In particular, we investigate two theoretically relevant measures of vowel category overlap (acoustic vs. perceptual categorisation) as predictors of non-native discrimination difficulty. We also investigate whether the individual listener’s own native vowel productions predict non-native vowel perception better than group averages. The results showed comparable performance for AusE and ES participants in their perception of the BP vowels. In particular, discrimination patterns were largely dependent on contrast-specific learning scenarios, which were similar across AusE and ES. We also found that acoustic similarity between individuals’ own native productions and the BP stimuli were largely consistent with the participants’ patterns of non-native categorisation. Furthermore, the results indicated that both acoustic and perceptual overlap successfully predict discrimination performance. However, accuracy in discrimination was better explained by perceptual similarity for ES listeners and by acoustic similarity for AusE listeners. Interestingly, we also found that for ES listeners, the group averages explained discrimination accuracy better than predictions based on individual production data, but that the AusE group showed no difference.

Introduction: Pneumomediastinum (PM) is characterized by the presence of air within the mediastinum. The association between PM and coronavirus 2019 (COVID-19) has not been well established in the current literature. We sought to summarize the limited body of literature regarding PM in patients with COVID-19 and characterize the presentation and clinical outcomes of PM in patients with severe acute respiratory syndrome (SARS)-COV-2 pneumonia at our institution to better define the incidence, prognosis, and available treatment for this condition. Materials and Methods: All patients with a proven diagnosis of COVID-19 and PM between March 18, 2020 and May 5, 2020 were identified through hospital records. Retrospective analysis of radiology records and chart review were conducted. Clinical characteristics and outcomes were collected and descriptive statistics was analyzed. Results: Thirty-six patients met inclusion criteria. Out of the 346 intubated COVID-19 patients, 34 (10%) had PM. The incidence of PM increased for the first 4 weeks of the pandemic, and then began to decrease by week 5. At the endpoint of the study, 12 (33.33%) patients were alive and 24 patients (66.67%) had died. Conclusion: PM, although a rare phenomenon, was more prevalent in COVID-19 patients compared with historical patients with adult respiratory distress syndrome. The etiology of this condition may be attributed to higher susceptibility of patients infected with SARS-CoV-2 to a combination of barotrauma and airway injury.

Barney’s elaboration on the resource-based view had a major impact on research in strategic human resource management (SHRM) and beyond. In this article, I reflect on its influence and use in SHRM research and analyze the strengths and limitations of the original work. I also review various spinoffs and expansions of the original work as well as trends in empirical SHRM research.

‘Vocalization’ is a label commonly used to describe an ongoing change in progress affecting coda /l/ in multiple accents of English. The label is directly linked to the loss of consonantal constriction observed in this process, but it also implicitly signals a specific type of change affecting manner of articulation from consonant to vowel, which involves loss of tongue lateralization, the defining property of lateral sounds. In this study, we consider two potential diachronic pathways of change: an abrupt loss of lateralization which follows from the loss of apical constriction, versus slower gradual loss of lateralization that tracks the articulatory changes to the dorsal component of /l/. We present articulatory data from seven speakers of New Zealand English, acquired using a combination of midsagittal and lateral EMA, as well as midsagittal ultrasound. Different stages of sound change are reconstructed through synchronic variation between light, dark, and vocalized /l/, induced by systematic manipulation of the segmental and morphosyntactic environment, and complemented by comparison of different individual articulatory strategies. Our data show a systematic reduction in lateralization that is conditioned by increasing degrees of /l/-darkening and /l/-vocalization. This observation supports the idea of a gradual diachronic shift and the following pathway of change: /l/-darkening, driven by the dorsal gesture, precipitates some loss of lateralization, which is followed by loss of the apical gesture. This pathway indicates that loss of lateralization is an integral component in the changes in manner of articulation of /l/ from consonantal to vocalic.

In this article, we aim to address 2 important questions: (a) Are women less likely than men to occupy network brokerage positions? And if so, (b) what mechanisms may explain their fewer brokerage roles? Study 1, a meta-analysis examining gender differences in network brokerage, analyzed a cumulative sample of 15,743 individuals (69 independent samples) to show that women were less likely to be brokers in both instrumental and expressive networks, which partly explained their lower career success. Study 2, a follow-up study with 2 independent samples of new employees (n = 150 and 245, respectively), examined both structural opportunity (job-based opportunity and workplace discrimination) and individual agency (proactive networking) as potential mechanisms underlying the relationship between gender and network brokerage. Results of these 2 samples consistently show that proactive networking mediated gender's effect on network brokerage that was measured 6 months after the new employees entered their organizations. The predictions regarding the mediation effects of job-based opportunity and workplace discrimination were not supported. Our findings offer valuable insights into the relative positions of women and men in informal structures of organizational networks, advance our understanding of gender inequality in career outcomes, and shed new light on the relative importance of individual agency and structural opportunity in explaining individuals' occupancy of advantageous network positions.

Composite plating with particles embedded into the metal matrix can enhance the properties of the metal coating to make it more or less conductive, hard, durable, lubricated or fluorescent. However, it can be more challenging than metal plating, because the composite particles are either 1) not charged so they do not have a strong electrostatic attraction to the cathode, 2) are hygroscopic and are blocked by a hydration shell, or 3) too large to remain stagnate at the cathode while stirring. Here, we describe the details of a bathless plating method that involves anode and cathode nickel plates sandwiching an aqueous concentrated electrolyte paste containing large hygroscopic phosphorescent particles and a hydrophilic membrane. After applying a potential, the nickel metal is deposited around the stagnant phosphor particles, trapping them in the film. The composite coatings are characterized by optical microscopy for film roughness, thickness and composite surface loading. In addition, fluorescence spectroscopy can be used to quantify the illumination brightness of these films to assess the effects of various current densities, coating duration and phosphor loading.

The impacts of COVID-19 on workers and workplaces across the globe have been dramatic. This broad review of prior research rooted in work and organizational psychology, and related fields, is intended to make sense of the implications for employees, teams, and work organizations. This review and preview of relevant literatures focuses on (a) emergent changes in work practices (e.g., working from home, virtual teamwork) and (b) emergent changes for workers (e.g., social distancing, stress, and unemployment). In addition, potential moderating factors (demographic characteristics, individual differences, and organizational norms) are examined given the likelihood that COVID-19 will generate disparate effects. This broad-scope overview provides an integrative approach for considering the implications of COVID-19 for work, workers, and organizations while also identifying issues for future research and insights to inform solutions. (PsycInfo Database Record (c) 2021 APA, all rights reserved) Public Significance Statement—COVID-19 has disrupted work and organizations across the globe. This overview integrates and applies prior research in work and organizational psychology as well as related fields in its examination of emergent changes for work practices as well as workers. This article also acknowledges and considers the disproportionate impacts that COVID-19 may have on workers depending on demographic characteristics, individual differences, and relevant organizational norms. In addition to helping make sense of the implications of COVID-19 for employees, teams, and work organizations, this review features roadmaps for future research and action.

Increased fall risk has been linked to age, being female, and age-related changes in the postural control system. The purpose of this study was to determine if a portable balance system could predict fall risk by determining the relationship among the modified Clinical Test for Sensory Interaction on Balance (mCTSIB) scores, age, the Activities-specific Balance Confidence Scale (ABC) score, and the Berg Balance Scale (BBS) score in community-dwelling older women. Insight into these relationships may facilitate early intervention and decrease fall risk in older women.This study was a non-experimental, prospective, cross-sectional, exploratory analysis to determine the relationship among the mCTSIB, age, ABC, and BBS. Women aged 65 years and over were selected from two independent living facilities using a sample of convenience (n=42).The mCTSIB firm surface, eyes open and the ABC predicted fall risk (BBS) scores, F(2, 36)=35.72, p0.001, R2=0.67, but adding age did not significantly improve the model, b= -0.17, t(36)= -1.71, p=0.10.A portable balance system may be an effective screening tool to predict fall risk in community-dwelling older women and may be used by a variety of allied health professionals. Postural sway, and perceived balance, predicted fall risk scores (BBS). More specifically, data obtained from the mCTSIB firm surface, eyes open test condition when combined with ABC scores could lead to identification of increased fall risk, allowing clinicians to recommend early treatment intervention to prevent future falls.

The average predictability (aka informativity) of a word in context has been shown to condition word duration (Seyfarth, 2014). All else being equal, words that tend to occur in more predictable environments are shorter than words that tend to occur in less predictable environments. One account of the informativity effect on duration is that the acoustic details of probabilistic reduction are stored as part of a word's mental representation. Other research has argued that predictability effects are tied to prosodic structure in integral ways. With the aim of assessing a potential prosodic basis for informativity effects in speech production, this study extends past work in two directions; it investigated informativity effects in another large language, Mandarin Chinese, and broadened the study beyond word duration to additional acoustic dimensions, pitch and intensity, known to index prosodic prominence. The acoustic information of content words was extracted from a large telephone conversation speech corpus with over 400,000 tokens and 6,000 word types spoken by 1,655 individuals and analyzed for the effect of informativity using frequency statistics estimated from a 431 million word subtitle corpus. Results indicated that words with low informativity have shorter durations, replicating the effect found in English. In addition, informativity had significant effects on maximum pitch and intensity, two phonetic dimensions related to prosodic prominence. Extending this interpretation, these results suggest that predictability is closely linked to prosodic prominence, and that the lexical representation of a word includes phonetic details associated with its average prosodic prominence in discourse. In other words, the lexicon absorbs prosodic influences on speech production., 41 pages, 1 figure

Purpose: The purpose of this study is to retrospectively evaluate the technical efficacy, safety, and treatment outcomes of percutaneous radiofrequency ablation (RFA) of lung tumors in patients not amenable to surgery at an urban community hospital. Materials and Methods: Informed consent and IRB approval was obtained. Eligible tumors were defined as those in patients deemed poor surgical candidates by multidisciplinary consensus or those refusing surgery. Response to treatment was assessed by computed tomography (CT) performed immediately postprocedure and regular intervals up to 36 months later. Complete response was measured as a 30% decrease in mean tumor diameter without evidence of contrast enhancement or tumor growth within the ablation zone as defined by the response evaluation in solid tumors. Patient demographics, technical success, postprocedure complications, and survival were assessed and compared with data available in literature. Results: Twenty-four patients with a total of 29 tumors underwent percutaneous CT guided RFA for biopsy-proven lung malignancies between 2010 and 2016. Complete response was achieved in 82% (14/17) of treated tumors in patients who complied with postprocedure imaging recommendations. Immediate postprocedure complications occurred following 27.6% (8/29) ablations with pneumothorax being the most common, 17.2% (6/29). Mean survival is 28.5 months (95% confidence interval: 19.7–37.3). Progressive disease was seen in 18% (3/17) patients. No immediate treatment mortality was found. No significant difference was found in survival in patients with multiple comorbidities as measured by the Charlson Comorbidity Index. Conclusions: RFA of lung tumors is a well-tolerated procedure with low incidence of minor complications, a good tumor response and survival benefit in selected patients in the community setting. This is a positive endorsement of the potential success of tumor RFA programs outside of the academic setting. In addition, patients with multiple comorbidities should still be considered candidates for RFA as no difference was seen in survival in patients with multiple medical comorbidities.

High vowels in Tokyo Japanese are typically devoiced between voiceless obstruents, but controversy remains over whether vowel gestures persist when devoiced or are instead deleted. A previous ultrasound study (Iwasaki et al ., 2020) showed that the lingual articulation of the release burst of /kV/ differs by vowel context even when the vowels are devoiced. This study uses tongue surface contours derived from midsagittal ultrasound images to investigate the effects of vowel devoicing on changes in quantified tongue shape over time. Native speakers of Tokyo Japanese produced word pairs (/C1VC2e/) that contrasted in the voicing of V, which was either /i/ or /u/. Tongue shape was characterized by Fourier transforming tangent angles along each contour (Dawson et al., 2016). Time-normalized trajectories over the /C1VC2e/ sequence were compared by vowel context (/i/ versus /u/) and voicing environment (devoiced versus voiced). Preliminary results show that the real component of the first Fourier coefficient is sensitive todetecting evolving shape differences between the two vowel contexts over the sequence, not just when the vowels are voiced, but also when they are devoiced. Based on these results, the high vowel contrast persists even in the devoiced environment, suggesting that devoiced vowels are not deleted.

Background and purpose An accurate fall risk assessment is an important component of fall prevention, though a fall could occur during testing. To minimize this risk, different guarding methods are used, though there is disagreement regarding the optimal method. The purpose of this study was to compare the effect of 2 guarding methods, contact guarding (CG) and standby guarding (SG), on performance during the Functional Gait Assessment (FGA). We hypothesized that (1) there would not be a significant difference in FGA scores when comparing CG with SG, and (2) participants would not perceive a difference between the 2 guarding methods. Methods Twenty-three community-dwelling older adults, mean age 73.6 (SD = 6.2) years, participated in this study. Each participant completed 2 trials of the FGA, one with CG and another with SG. Guarding for all trials was provided by the same experienced physical therapist (PT) for this within-subjects design. All trials were video recorded for review by 2 PT raters who were blinded to the purpose of the study. Results and discussion Functional Gait Assessment scores for the 2 PT raters indicated high internal agreement for both CG and SG conditions (CG: intraclass correlation coefficient [ICC] = 0.949; SG: ICC = 0.935), and CG FGA scores did not significantly differ from SG FGA scores (t22 = 0.15, P = .882). Furthermore, none of the participants perceived a difference in guarding methods. Conclusions The results of this study indicate that hands-on guarding does not significantly influence performance on the FGA when the guarding is provided by an experienced PT and the participant is a community-dwelling older adult.

Many previous studies have argued that phonology may leave some phonetic dimensions unspecified in surface representations. We introduce computational tools for assessing this possibility though simulation and classification of phonetic trajectories. The empirical material used to demonstrate the approach comes from electromagnetic articulography recordings of high-vowel devoicing in Japanese. Using Discrete Cosine Transform, tongue-dorsum movement trajectories are decomposed into a small number of frequency components (cosines differing in frequency and amplitude) that correspond to linguistically meaningful signal modulations, i.e. articulatory gestures. Stochastic generators of competing phonological hypotheses operate in this frequency space. Distributions over frequency components are used to simulate (i) the vowel-present trajectories and (ii) the vowel-absent trajectories. A Bayesian classifier trained on simulations assigns posterior probabilities to unseen data. Results indicate that /u/ is optionally produced without a vowel-height specification in Tokyo Japanese and that the frequency of such targetlessness varies systematically across phonological environments.

Researchers once lamented the paucity of multilevel theory, models, and research in the literature (e.g., O’Reilly, 1990; Staw, 1984), but now management journals are replete with such studies. Around a decade ago, Hitt, Beamish, Jackson, and Mathieu (2007) noted that about a quarter of recent management publications were multilevel—undoubtedly, the trajectory remains positive. The proliferation may provide support for the adage that “the squeaky wheel gets the grease,” but it likely also reflects the field’s desire to develop more comprehensive, context-rich theory and findings. Moreover, the availability of “how to” volumes for developing multilevel theory and analyzing the associated data (e.g., Johns, 2001, 2006; Kozlowski & Klein, 2000), as well as the widespread availability of accessible statistical packages, contributes to the movement. The shift is both symbolic and substantive. The multilevel context—once treated as an unknown or messy source of error variance that needed to be controlled—is frequently at the heart of theorizing on a variety of topics. This is perhaps most evident in the teams literature (see Mathieu, Maynard, Rapp, & Gilson, 2008, for a review) where multilevel studies examine direct cross-level effects as well as contextual moderators that influence lower-level processes and outcomes (e.g., Yu & Zellmer-Bruhn, 2018).1But, the influence is apparent in other streams as well, including strategic human resource management (Ployhart,Weekley, & Ramsey, 2009), emotions (Scott, Barnes, & Wagner, 2012), social networks (Brass, Galaskiewicz, Greve, & Tsai, 2004), and many others.

Does our research impact management practice? That is, does it influence how practitioners think, talk, or perform their work?

In Tokyo Japanese, /u/ is typically devoiced between two voiceless consonants. Whether the lingual vowel gesture is influenced by devoicing or present at all in devoiced vowels remains an open debate, largely because relevant articulatory data has not been available. We report ElectroMagnetic Articulography (EMA) data that addresses this question. We analyzed both the trajectory of the tongue dorsum across VC1uC2V sequences as well as the timing of C1 and C2. These analyses provide converging evidence that /u/ in devoicing contexts is optionally targetless—the lingual gesture is either categorically present or absent but seldom reduced. When present, the magnitude of the lingual gesture in devoiced /u/ is comparable to voiced vowel counterparts. Although all speakers produced words with and without a vowel height target for /u/, the frequency of targetlessness varied across speakers and items. The timing between C1 and C2, the consonants flanking /u/ was also effected by devoicing but to varying degrees across items. The items with the greatest effect of devoicing on this inter-consonantal interval were also the items with the highest frequency of vowel height targetlessness for devoiced /u/.

Merger between a voiceless labiodental fricative, [f], and a voiceless velar fricative, [x], is common across languages, including many varieties of Chinese, particularly those spoken in Southwestern China. The sound changes that lead to merger in Southwestern Mandarin varieties are bidirectional: in some, [f] becomes [x]; in others [x] becomes [f]. We conducted a study of phonetic variation in one such variety, Zhongjiang (中江) Chinese, which has been reported to merge labialized [x], i.e., [xw], to [f]. Our results confirm this basic pattern while revealing additional nuances, including a new environment, [_oŋ], which conditions merger in the opposite direction, [x] becomes [f], and new phonetic details. In particular, [x] exhibits a particularly low spectral Center of Gravity (CoG) and [f] exhibits a wide range of spectral variation, including tokens with low CoG, characteristic of a velar constriction. We interpret these patterns in the context of areal variation, proposing a pathway to change that relates spectral variation attributable to gestural overlap to diachronic observations of labio-velar merger.

Research on English and other languages has shown that syllables and words that contain more information tend to be produced with longer duration. This research is evolving into a general thesis that speakers articulate linguistic units with more information more robustly. While this hypothesis seems plausible from the perspective of communicative efficiency, previous support for it has come mainly from English and some other Indo-European languages. Moreover, most previous studies focus on global effects, such as the interaction of word duration and sentential/semantic predictability. The current study is focused at the level of phonotactics, exploring the effects of local predictability on vowel duration in Japanese, using the Corpus of Spontaneous Japanese. To examine gradient consonant-vowel phonotactics within a consonant–vowel-mora, consonant-conditioned Surprisal and Shannon Entropy were calculated, and their effects on vowel duration were examined, together with other linguistic factors that are known from previous research to affect vowel duration. Results show significant effects of both Surprisal and Entropy, as well as notable interactions with vowel length and vowel quality. The effect of Entropy is stronger on peripheral vowels than on central vowels. Surprisal has a stronger positive effect on short vowels than on long vowels. We interpret the main patterns and the interactions by conceptualizing Surprisal as an index of motor fluency and Entropy as an index of competition in vowel selection.

Background: Almost 25% of thyroid goiters have an intrathoracic component. Although the majority of mediastinal goiters may be approached through a cervical approach, up to a third of substernal goiters require a sternotomy or thoracotomy for resection. As an alternative to conventional sternotomy, we herein describe a combined anterior thoracoscopic and transcervical approach to large mediastinal thyroid goiters. Methods: Between 2012 and 2015, seven patients with symptomatic thyroid goiters with significant intrathoracic extension were approached via simultaneous cervical exploration and anterior thoracoscopy. Thoracoscopy was performed on the side of maximal goiter extension. Results: Simultaneous thoracoscopy and transcervical thyroidectomy was technically successful in all patients. No patients required conversion to open approach and one patient required reoperation for hemorrhage. Conclusions: Simultaneous anterior thoracoscopy and cervical exploration is a safe and effective approach to large mediastinal thyroid goiter. Patients with significant intrathoracic goiter extension may benefit from preoperative thoracic surgical evaluation and planned thoracoscopy at the time of thyroidectomy.

In studies of dialect variation, the articulatory nature of vowels is sometimes inferred from formant values using the following heuristic: F1 is inversely correlated with tongue height and F2 is inversely correlated with tongue backness. This study compared vowel formants and corresponding lingual articulation in two dialects of English, standard North American English, and Australian English. Five speakers of North American English and four speakers of Australian English were recorded producing multiple repetitions of ten monophthongs embedded in the /sVd/ context. Simultaneous articulatory data were collected using electromagnetic articulography. Results show that there are significant correlations between tongue position and formants in the direction predicted by the heuristic but also that the relations implied by the heuristic break down under specific conditions. Articulatory vowel spaces, based on tongue dorsum position, and acoustic vowel spaces, based on formants, show systematic misalignment due in part to the influence of other articulatory factors, including lip rounding and tongue curvature on formant values. Incorporating these dimensions into dialect comparison yields a richer description and a more robust understanding of how vowel formant patterns are reproduced within and across dialects.

Companies invest enormous financial resources in reward systems and practices to attract, retain, and motivate employees and thereby ensure and improve individual, team, and organizational effectiveness. Organizational rewards comprise financial and nonfinancial rewards, such as appreciation, job security, and promotion. Financial rewards, also called tangible rewards, include direct forms (such as fixed and variable pay and share ownership) as well as indirect and/or deferred forms (such as benefits and perquisites). Fixed or base pay refers to the amount of money one receives in return for fulfilling one’s job requirements, the job’s grade, or the skill or competence level required to perform the tasks. Variable pay (such as cash bonuses and commissions as forms of short-term incentives, or stocks or stock options as forms of long-term incentives) depends, for example, on individual, team, and/or company performance or outcomes, and is based on quantitative and/or qualitative criteria. Benefits (such as pension plans or health programs) and perquisites (such as onsite fitness centers, medical care or health facilities, and company cars), among other forms, are indirect financial rewards (Milkovich, Newman, & Gerhart, 2016). Both qualitative reviews (Gerhart & Fang, 2014; Shaw & Gupta, 2015) and meta-analytic studies (Cerasoli, Nicklin, & Ford, 2014; Garbers & Konradt, 2014; Jenkins, Mitra, Gupta, & Shaw, 1998) have shown that extrinsic rewards (such as financial incentives) can improve employee motivation and performance and shape employee health (Giles, Robalino, McColl, Sniehotta, & Adams, 2014) and safety behavior (Mattson, Torbiörn, & Hellgren, 2014). However, empirical evidence regarding under which conditions particular rewards are most effective or lead to unintended consequences is still scarce. In short, compensation and incentive systems remain one of the most under-researched areas in personnel psychology and human resource management (Gupta & Shaw, 2015). \ud \ud This state of affairs poses risks. Reward management approaches may waste both money and effort, and may be ineffective in attracting, retaining, and motivating target personnel, if not grounded in a base of evidence. Added to this, in the face of the recent financial crisis and of serious cases of employee and company unethical behavior, company’s financial incentives, especially bonus and pay-for-performance (pfp) systems, have been widely criticized for their detrimental effects on individuals, companies, and society (Larcker, Ormazabal, Tayan, & Taylor, 2014). These examples of the dark sides of incentives highlight the importance of reward management research, not only from a human resources management (HRM) but also from a societal perspective. They also illustrate the need to understand the underlying mediating and moderating mechanisms linking reward systems and practices to individual, team, and organizational behavior and outcomes. This special issue contributes to the research on reward management by focusing on the contextual effects of financial rewards on employee motivation, behavior, and performance, and by analyzing the mediating mechanisms of different types of financial and nonfinancial rewards. \ud \ud The four studies included in this special issue address different issues of reward management research and take different theoretical perspectives. The first two studies analyze the interaction effects of financial incentives and individual factors, such as employee perceptions of distributive justice, and then how individual competitiveness moderates the effects of pay-for-performance (pfp) on employee motivation, behavior, and performance. These studies show which and how intended or unintended consequences of pfp occur. The other two studies differentiate the effects of tangible and intangible rewards on employee turnover and risk taking; they disentangle underlying mediating and moderating mechanisms by comparing the effects of benefits and perquisites, and of esteem, security, and promotion as nonfinancial rewards. In the following passages, we present a short overview of these four papers before we discuss their contribution and their implications for further research.
