Rent appropriation of knowledge‐based assets and firm performance when institutions are weak: A study of Chinese publicly listed firms
Authors: Qian Cuili , Wang Heli , Geng Xuesong , Yu Yangxin
Published: March 2016

Research summary: A firm's strategic investments in knowledge‐based assets through research and development (R&D) can generate economic rents for the firm, and thus are expected to affect positively a firm's financial performance. However, weak protection of minority shareholders, weak property rights, and ineffective law enforcement can allow those rents to be appropriated disproportionately by a firm's powerful insiders such as large owners and top managers. Recent data on Chinese publicly listed firms during 2007–2012 were used to demonstrate that the expected positive relationship between knowledge assets and performance is weaker in transition economies when a firm's ownership is highly concentrated and its managers have wide discretion. Moreover, rent appropriation by insiders was shown to vary with the levels of institutional development in which a firm operates.

Managerial summary: Investing in knowledge‐based intangible assets (e.g.,R&D) is an important value‐creation activity for the firm. Such value creation process can be facilitated by large shareholders and powerful managers, who can then take an advantageous position with critical insider information on these valuable intangible assets and therefore enjoy more opportunities to appropriate more value from them, leaving less value for other minority shareholders. The value distribution becomes increasingly skewed against minority shareholders when the institutional protection for them is weak. Indeed, in a large sample of Chinese publicly listed firms, we found thatR&Dinvestment becomes less positively associated with firm financial performance with the presence of large shareholders, high managerial equity, orCEO/Chairman duality, especially in Chinese provinces with weak institutional development.

Smart Polymers with Special Wettability
Authors: Chang Baisong , Zhang Bei , Sun Taolei
Published: March 2016

Surface wettability plays a key role in addressing issues ranging from basic life activities to our daily life, and thus being able to control it is an attractive goal. Learning from nature, both of its structure and function, brings us much inspiration in designing smart polymers to tackle this major challenge. Life functions particularly depend on biomolecular recognition‐induced interfacial properties from the aqueous phase onto either “soft” cell and tissue or “hard” inorganic bone and tooth surfaces. The driving force is noncovalent weak interactions rather than strong covalent combinations. An overview is provided of the weak interactions that perform vital actions in mediating biological processes, which serve as a basis for elaborating multi‐component polymers with special wettabilities. The role of smart polymers from molecular recognitions to macroscopic properties are highlighted. The rationale is that highly selective weak interactions are capable of creating a dynamic synergetic communication in the building components of polymers. Biomolecules could selectively induce conformational transitions of polymer chains, and then drive a switching of physicochemical properties, e.g., roughness, stiffness and compositions, which are an integrated embodiment of macroscopic surface wettabilities.
Taking a wider view on climate governance: moving beyond the ‘iceberg,’ the ‘elephant,’ and the ‘forest’
Authors: Aykut Stefan C.
Published: March 2016

Attention in the literature on global climate politics has recently turned from a focus on intergovernmental negotiations to conceptualizing climate governance ‘beyond’ or ‘outside’ the UN regime. However, this literature differs on three key aspects: the underlying research paradigms, what is identified as the heart of the problem, and proposed solutions. One group of scholars calls for an attention shift from the ‘tip of the iceberg’ of climate governance to its much larger ‘hidden parts,’ conceptualized through notions such as the ‘climate change regime complex,’ a ‘fragmented climate governance architecture,’ and ‘transnational climate governance.’ A second set of authors points to the ‘elephant in the room,’ namely underlying power structures and material configurations in the international system that block effective responses to the climate crisis. A third group has argued that instead of looking at the individual ‘trees’ of climate negotiations, research should focus on the ‘forest’ of climate governance, made up of framings, norms, and emerging ‘climate governmentalities.’ The article proposes the concept of a ‘schism of reality’ as a means to overcome this fragmentation of the literature. This notion offers a new way of understanding interactions between the climate regime and its wider environment by focusing on discrepancies and contradictions. It accommodates different theoretical perspectives and provides common ground for future research: on how paradoxes and contradictions are dealt with in climate governance; how they can be overcome; how current developments in climate governance reduce the schism; and where and why aspects of the schism persist.

Industrial energy use and carbon emissions reduction: a UK perspective
Authors: Griffin Paul W. , Hammond Geoffrey P. , Norman Jonathan B.
Published: March 2016

Progress in reducing industrial energy demand and carbon dioxide (CO2
) emissions is evaluated with a focus is on the situation in the United Kingdom (UK), although the lessons learned are applicable across much of the industrialized world. The UK industrial sector is complex, because it may be viewed as consisting of some 350 separate combinations of subsectors, devices and technologies. Various energy analysis and carbon accounting techniques applicable to industry are described and assessed. The contributions of the energy‐intensive (EI) and nonenergy‐intensive (NEI) industrial subsectors over recent decades are evaluated with the aid of decomposition analysis. An observed drop in aggregate energy intensity over this timescale was driven by different effects: energy efficiency improvements; structural change; and fuel switching. Finally, detailed case studies drawn from the Cement subsector and that associated with Food and Drink are examined; representing the EI and NEI subsectors, respectively. Currently available technologies will lead to further, short‐term energy and CO2 emissions savings in manufacturing, but the prospects for the commercial exploitation of innovative technologies by mid‐21st century are far more speculative. There are a number of nontechnological barriers to the take‐up of such technologies going forward. Consequently, the transition pathways to a low carbon future in UK industry by 2050 will exhibit large uncertainties. The attainment of significant falls in carbon emissions over this period depends critically on the adoption of a limited number of key technologies [e.g., carbon capture and storage (CCS), energy efficiency techniques, and bioenergy], alongside a decarbonization of the electricity supply.

Analysis of saliva and gingival crevice fluid by total reflection X‐ray fluorescence (TXRF)
Authors: Cleto Daniele Aparecida Maia , Andrello Avacir Casanova , Netto Ítalo José Vitorino , Appoloni Carlos Roberto
Published: March 2016

The study of liquid biological samples with the use of various techniques has become a routine task nowadays. Saliva has been a study object for the correlation of chemical elements with a disorder in human body. Saliva is an aqueous hypotonic fluid and transparent and produced by various secretory glands (parotid, submandibular, sublingual, and smaller glands).

This paper uses the technique of total reflection X‐ray fluorescence (TXRF) to analyze saliva samples collected in duct of the parotid gland and the gingival crevice between first (tooth 46) and second (tooth 47) grinding teeth of seven individuals. Using the TXRF technique, the main objective of this work was to assess the results obtained quali‐quantitatively.

The chemical elements identified in saliva samples of the parotid gland and the gingival crevice were P, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Se, Br, Rb, and Pb. Although different elements have been identified in the analyzed samples, the identified chemical elements have varied from one individual to another. Comparing the results obtained from the saliva samples of parotid gland and the gingival crevice, it could be observed in the gingival crevice other elements not found in the parotid gland. Therefore, the sampling strategy and the TXRF technique was able to differentiate chemical elements in the samples of the parotid gland and the gingival crevice.

Evaluation of thermal regimes for transported ambassador ectotherms: One size does not fit all
Authors: Tetzlaff Sasha J. , Tetzlaff Kristin E. , Connors Richard J.
Published: March 2016

Providing appropriate environmental temperatures for captive ectotherms should be a husbandry priority. This can be especially challenging for ectotherms that are routinely transported, such as those used in education programs at zoos, because they are unable to thermoregulate while confined in non‐temperature controlled, compact carriers. To assess if ectotherms used in the Fort Wayne Children's Zoo's outreach programs experienced appropriate transit temperatures during cold weather, we placed temperature loggers inside two sizes of transport carriers, half containing a heat source (bottle of hot water) and half not (control). While transport temperatures were appropriate for many ectotherms, this simple procedure failed to meet the thermal preferences of species with relatively low or high preferred temperatures such as the eastern tiger salamander (Ambystoma tigrinum) and the spiny‐tailed lizard (Uromastyx maliensis), respectively. We found large heated carriers were warmer than small heated carriers, but the temperatures of control carriers did not differ. Despite considerable interspecific variation, large heated carriers provided higher thermal quality environments than both small heated and control carriers for all species except eastern tiger salamanders. We suggest further thermal monitoring of ectotherms during transit with the aim of identifying appropriate heat sources and developing efficient and effective transportation protocols. This could be achieved by modifying transport carriers so that animals are able to thermoregulate. Limiting or ceasing their use when appropriate temperatures cannot be provided may be necessary. Particular attention should be given to species with temperature preferences markedly different than the majority of others in a given collection.

Stimuli Responsive Self‐Assembly of 3‐(Octyloxy)‐3‐Oxopropyl Acrylate‐Co‐Acrylic Acid Polymer in Aqueous Media
Authors: Kumar Pandari Phani , Nayak Rati Ranjan , Shivaraju Akula , Amarnath Narayana , Sreedhar Bojja , Chakrabarti Pradosh Prasad , Kanjilal Sanjit
Published: March 2016

A novel copolymer based on 3‐(alkyloxy)‐3‐oxopropyl acrylate and acrylic acid was synthesized and characterized. Surface tension and fluorescence probe techniques (using N‐phenyl‐1‐naphthylamine as a probe) were employed to evaluate the surface properties of the amphiphilic copolymer. The copolymer was found to reduce the surface tension of water to 40–46 mN/m depending on the pH of the medium. The critical aggregation concentration of the copolymer determined by surface tension measurements was found to be 0.28 mg/ml at pH 4, 1.13 mg/ml at pH 8, and 1.44 mg/ml at pH 10, very close to those obtained by steady state fluorescence probe techniques (0.21, 1.13 and 1.48 mg/ml, respectively, at pH 4, 8, and 10). The pH‐induced structural transitions of the copolymer were also studied using steady state fluorescence with pyrene and 1,6‐diphenyl‐1,3,5‐hexatriene as probes, dynamic light scattering and transmission electron microscopy. The protonation of pendant carboxylate groups at acidic pH makes the aggregate compact and rigid. Conversely, ionization of the carboxylate groups under alkaline conditions resulted in larger aggregates.
Evidence vs. efficacy in allergen-specific immunotherapy: Considerations using the example of tradable products in Germany
Authors: Brehler Randolf , Klimek Ludger , Vogelberg Christian , Werfel Thomas , Pfaar Oliver , Hamelmann Eckard
Published: March 2016

The recently published S2k-guideline on (allergen-) specific immunotherapy (AIT) provides an excellent overview of the evidence on allergen preparations available for AIT in Germany based on the published efficacy studies. Publications based on the guideline are currently being used by the German associations of statutory health insurance physicians and German health insurance funds to open a discussion on the reimbursement status of allergen preparations. In our view, calling the reimbursement status of perscribable and tradable AIT preparations into question on the basis of an assessment of the current body of evidence in the guideline is to be rigidly opposed. In Germany the Paul Ehrlich Institute (PEI) is the only authority empowered to decide on the marketability of AIT preparations, and decisions on the reimbursement status of AIT products need to be based on cost-benefit analyses and not solely on an evaluation of the evidence. The present article aims to examine the relationship between the evidence, efficacy, tradability, and reimbursability of AIT preparations.
Clinical spectrum of α-Gal syndrome: from immediate-type to delayed immediate-type reactions to mammalian innards and meat
Authors: Fischer Jörg , Yazdi Amir S. , Biedermann Tilo
Published: March 2016

The term α-Gal syndrome describes a novel IgE-mediated immediate-type allergy to the disaccharide galactose-α-1,3-galactose (α-Gal). Its classification as a syndrome is proposed on the basis of its clinical relevance in three different fields of allergy: food, drugs, and tick bites. The main focus of the present article is on α-Gal as an eliciting allergen in food allergy. It was recently shown that immediate-type allergies to pork kidney and other mammalian innards belong to the spectrum of α-Gal syndrome. These allergic reactions manifest as classic immediate-type allergies with a typical latency of under 1 h. The phenomenon of a delayed-onset immediate-type allergy with a latency of 3–6 h following ingestion of mammalian meat is considered pathognomonic for α-Gal syndrome. This clinically distinct type of presentation can be explained using the concept of food-dependent exercise-induced anaphylaxis (FDEIA). However, clinical observations and challenge testing in this constellation reveal that individual sensitivity in α-Gal patients is highly variable and which broadens our basic understanding of α-Gal syndrome.
Dispersion reduction of artillery rockets guided by flight path steering method
Authors: Mandić S.
Published: March 2016

Artillery rockets are sensitive to disturbances (total impulse variation, wind, thrust misalignment, etc.). As the range of ground-to-ground rockets increases, the accuracy of free flight rockets decreases. Requirements for the increase of the range and minimisation of the impact point dispersions can be solved by adding guidance and control systems to rockets. Based on the differences between the measured flight parameters and the calculated parameters for the nominal trajectory, the flight path angle correction algorithm is obtained by adding the correction to the nominal value. The flight path steering guidance system with lateral acceleration autopilot in the inner loop, is used for the guidance of hypothetical artillery rockets. The guidance algorithm given in this paper eliminates the time correction due to rocket velocity variations. Efficiency of the proposed algorithm is illustrated by numerical simulation. There is no practical influence of the external disturbances on impact point dispersion. It is also shown that the measurement errors of the inertial measurement unit are the dominant factor affecting impact point dispersion of artillery rockets modified by adding a guidance system based on the flight path steering method.
Investigation of effects of compressibility, geometric and flow parameters on the simulation of a synthetic jet behaviour
Authors: Bazdidi-Tehrani F. , Abouata A. , Hatami M. , Bohlooli N.
Published: March 2016

The present paper focuses on a three-dimensional unsteady turbulent synthetic jet to assess the accuracy of a compressible simulation and some important parameters including the simulations of the actuator, cavity height and Reynolds number. The two-equationSST/k− ω turbulence model is used to predict the flow behaviour. Results show that the compressible simulation case is more accurate than the incompressible one and the dynamic mesh exhibits more reliable results than the mass flow inlet boundary in the compressible simulation. The compressible case displays a delay in the phase of instantaneous velocity for all three Reynolds numbers. Also, the maximum of mean velocity is less than the incompressible case. Moreover, an increase in the Reynolds number leads to an amplification of the peak of mean velocity magnitude. Finally, results demonstrate that a reduction in the cavity height regarding the compressible simulation case causes a reduction in the phase delay and rise in peak of instantaneous velocity magnitude.
An overview of flow control activities at Dassault Aviation over the last 25 years
Authors: Rosenblum J.-P.
Published: March 2016

In France, the very first ideas on flow control were developed by Philippe Poisson-Quinton from the Office National d'Etudes et Recherches Aérospatiales (ONERA) in the 1950s. There was some renewal of this research topic in the early 1990s, first in the United States with scientists like Wygnanski and Gad-El Hak, and also in France at the initiative of Pierre Perrier from Dassault Aviation, who triggered a lot of research activities in this field both at ONERA and in the French National Centre for Scientific Research (CNRS) laboratories. The motivation was driven by the applications on Dassault Aviation military aircraft and Falcon business jets in order to contribute to the design, while facilitating performance optimisation and multi-disciplinary compromise. A few examples of flow control technologies, such as forebody vortex control, circulation control, flow separation control or boundary layer transition control using hybrid laminar flow control (HLFC), are presented to illustrate the applications and to explain the methodology used for the design of the flow control devices. The author also emphasises the current reaction of industry with respect to the integration of flow control technologies on an aircraft programme. The conclusion is related to the present status of the French research on this topic and to the next challenges to be addressed.
From “Occupy Central” to Democracy: Is a Referendum for Hong Kong Feasible and Desirable?
Authors: Lin Feng , Alati Daniel
Published: March 2016

This article seeks to utilize the existing literature on referendums to discuss the current situation in Hong Kong in order to make some theoretical and practical contributions to the field of constitutional studies. Theoretically, it attempts to situate and analyse Hong Kong’s current situation within Professor Tierney’s influential framework on constitutional referendums in order to further develop the constitutional theory in this area. Practically, it analyses, through comparative study, whether (and if so, how) referendums might provide a mechanism through which Hong Kong’s constitutional debate could productively move forward. It concludes by reiterating aspects of the Hong Kong experience that have aligned with, and further contributed to the constitutional theory on referendums and representative democracy. Moreover, it recommends that the Hong Kong Government begin consultations towards the tabling of legislation for a non-binding advisory referendum to be developed in accordance with the lessons learned from the jurisdictions discussed throughout the article.
Prototype Constitutional Supervision in China: The Lessons of the Hong Kong Basic Law Committee
Authors: IP Eric C.
Published: March 2016

Recurrent proposals to establish a constitutional supervisory committee have been pertinaciously rejected in spite of widespread recognition of the Chinese Constitution’s ineffectiveness. And yet, the Hong Kong Basic Law Committee has long epitomized in practice a prototypic form of constitutional supervision. Vested with quasi-judicial competences, the Committee seemed destined for a central role under the “One Country, Two Systems” arrangement. The tight secrecy imposed on its proceedings and the suppression of its potential to act consistently and with a distinct identity have fatally undermined the Committee’s ability to modulate constitutional tensions by way of coordinating expectations of the Basic Law’s proper meaning. The experience of the Basic Law Committee reveals the recalcitrance of the Party-state toward constitutional interpretation by any specialized body, even one whose powers are heavily circumscribed and whose membership is tightly controlled.
Rethinking Party System Nationalization in India (1952–2014)
Authors: Schakel Arjan H. , Swenden Wilfried
Published: March 2016

This article provides a new conceptual and empirical analysis of party system nationalization, based on four different measurements. Unlike previous nationalization studies, these measurements conceptualize party system nationalization on the basis of electoral performance in national (general or federal) and sub-national (state) elections. After introducing these measurements we apply them to 16 general and 351 state elections in India, the world’s largest democracy with strong sub-national governments. By incorporating state election results we are able to demonstrate that: (1) the pattern of denationalization in India has been more gradual than assumed in previous studies of party system nationalization; (2) denationalization in recent decades results less from dual voting (vote shifting between state and federal elections) than from the growing divergence among state party systems (in state and federal elections); (3) the 2014 general election result, although potentially transformative in the long run, provides more evidence of continuity than change in the short run.
Effects of side subsurface defects induced by CNC machine on the gain spatial distribution in neodymium phosphate glass
Authors: Wang Bingyan , Zhang Junyong , Shi Shuang , You Kewei , Zhu Jianqiang
Published: March 2016

The processing method applied to the side surface is different from the method applied to the light pass surface in neodymium phosphate glass (Nd:glass), and thus subsurface defects remain after processing. The subsurface defects in the side surface influence the gain uniformity of Nd:glass, which is a key factor to evaluate the performance of amplifiers. The scattering characteristics of side subsurface defects were simulated by finite difference time domain (FDTD) Solutions software. The scattering powers of the glass fabricated by a computer numerical control (CNC) machine without cladding were tested at different incident angles. The trend of the curve was similar to the simulated result, while the smallest point was different with the complex true morphology. The simulation showed that the equivalent residual reflectivity of the cladding glass can be more than 0.1% when the number of defects in a single gridding is greater than 50.
In Defense of the Situation: An Interactionist Explanation for Performance on Situational Judgment Tests
Authors: Harris Alexandra M. , Siedor Lane E. , Fan Yi , Listyg Benjamin , Carter Nathan T.
Published: March 2016

Whereas Lievens and Motowidlo (2016) propose a model of situational judgment test (SJT) performance that removes the “situation” in favor of conceptualizing SJTs as a measure of general domain knowledge, we argue that the expression of general domain knowledge is in fact contingent on situational judgment. As we explain, the evidence cited by Lievens and Motowidlo against a situational component does not inherently exclude the importance of situations from SJTs and does overlook the strong support for a person–situation interaction explanation of behavior. Based on the interactionist literature—in particular, the trait activation theory (TAT) and situational strength literatures—we propose a model that both maintains the key pathways and definitions posited by Lievens and Motowidlo and integrates the situational component of SJTs.
Clearly Defined Constructs and Specific Situations Are the Currency of SJTs
Authors: Chen Lijun , Fan Jinyan , Zheng Lu , Hack Elissa
Published: March 2016

Although we echo Lievens and Motowidlo's (2016) view that situational judgment test (SJT) research should subscribe to the construct-driven approach, we disagree with their argument on two counts. First, we question whether measuring general domain knowledge represents the only way to advance SJT research. Second, we question whether it is appropriate to downplay the importance of situations in SJTs. In this commentary, we first briefly review construct-driven SJT studies and then share our own experience in developing an SJT for integrity in China using the construct-driven approach. Based on the review and reflection, we come to two major conclusions: (a) construct-driven SJT research has progressed well so far without the reconceptualization of SJTs as measures of general domain knowledge, and (b) specific situations are an important feature of SJTs that should not yet be dismissed.
It's Time To Examine the Nomological Net of Job Knowledge
Authors: Torres W. Jackeline , Beier Margaret E.
Published: March 2016

Lievens and Motowidlo (2016) argue compellingly that situational judgment tests (SJTs) measure job-relevant general domain knowledge, conceptualized as implicit trait policies (ITPs). ITPs are defined as a person's knowledge about the utility of expressing certain traits. They develop through the feedback a person receives when acting in accordance with their trait profiles in different environments (work, life, leisure). Positive feedback reinforces the knowledge that behavior in accordance with one's own traits is appropriate, and negative feedback reinforces the knowledge that an approach that differs from one's trait tendencies may be more effective. As such, ITPs represent a person's knowledge about the effectiveness of behaviors across a variety of contexts.
Scoring SJTs for Traits and Situational Effectiveness
Authors: Harvey Robert J.
Published: March 2016

Lievens and Motowidlo (2016) addressed three of the most important unanswered questions regarding situational judgment tests (SJTs): (a) Should we view them as tests that can assess relatively generic constructs that predict performance across settings, (b) what constructs can they assess, and (c) how should they be scored? They suggested fundamentally changing the SJT development process by targeting the specific constructs we measure, using scoring systems that address both the targeted traits and their situational effectiveness, examining construct validity, and evaluating the criterion-related validity of SJT traits (Lievens & Motowidlo, pp. 11–12). These recommendations are highly significant on both practical and conceptual grounds.

Who Are These Workers, Anyway?
Authors: Griggs Tracy L. , Eby Lillian T. , Maupin Cynthia K. , Conley Kate M. , Williamson Rachel L. , Griek Olivia H. Vande , Clauson Muriel G.
Published: March 2016

The focal article by Bergman and Jean (2016) raises an important issue by documenting the underrepresentation of nonprofessional and nonmanagerial workers in industrial and organizational (I-O) research. They defined workers as, “people who were not executive, professional or managerial employees; who were low- to medium-skill; and/or who were wage earners rather than salaried” (p. 89). This definition encompasses a wide range of employee samples: from individuals working in blue-collar skilled trades like electricians and plumbers to police officers, soldiers, and call center representatives to low-skill jobs such as fast food, tollbooth operators, and migrant day workers. Because there is considerable variability in the pay, benefits, skill level, autonomy, job security, schedule flexibility, and working conditions that define these workers’ experiences, a more fine-grained examination of who these workers are is necessary to understand the scope of the problem and the specific subpopulations of workers represented (or not) in existing I-O research.
How Journals Can Facilitate the Study of Underlying Situational Characteristics Distinguishing Worker and Professional Samples
Authors: Green Jennifer P. , Dalal Reeshad S.
Published: March 2016

Bergman and Jean's (2016) focal article decries the limited research attention of industrial and organizational (I-O) psychologists on “workers”—that is, employees such as wage earners, frontline workers, and contractors, who do not fill professional, managerial, or executive positions. We agree. In addition to the scientific and moral benefits of studying workers, there is a practical imperative. An academic discipline that comes across as being disinterested in workers may leave itself open to charges of being the “handmaiden” of management (Hulin, 2002, p. 12). Moreover, such an academic discipline may be ill prepared to provide evidence-based contributions to important societal debates on topics such as income inequality and immigration.
What Else Are We Missing? Additional Issues Associated With Sample Misrepresentation
Authors: DeSimone Justin A.
Published: March 2016

Two recent focal articles in this journal have addressed issues related to sample selection and generalizability of results (Bergman & Jean, 2016; Landers & Behrend, 2015). If Bergman and Jean are correct, gone are the days of the Hawthorne studies in which research focused on the majority of the human workforce: the working class. Instead, researchers are allegedly two to three times as likely to exclusively sample managers as they are to exclusively sample workers. Assuming this is true, Bergman and Jean are correct to address why this occurs and how it may impact the field. However, there are two critical issues that must be considered alongside these questions: ongoing changes in how work is conducted and temporal trends in work. A consideration of these issues should yield additional insights that may supplement the recommendations made by Bergman and Jean.
News Flash! Work Psychology Discovers Workers!
Authors: Lefkowitz Joel
Published: March 2016

Bergman and Jean (2016) have contributed an important essay to the continuing self-reflection and maturation of the field of industrial–organizational (I-O) psychology—or as it is known in much of the world outside the United States, work psychology.1They clearly and adequately document that the field has relatively neglected to study the world of (largely lower-level) workers who are not managers, executives, professionals, or students and that this has affected adversely the validity of our science and the relevance of our professional practice in a number of not-so-intuitively obvious ways. But as critical as those observations are, I believe the most important aspect of their piece has to do with the inferences they offer as towhyour published literature is so skewed. They suggest six potential, not mutually exclusive, explanations, including the possibility of personal biases among I-O psychologists. However, before focusing on those explanations, it should be informative to place the Bergman/Jean thesis in context. There is a growing, recent body of critical evidence and/or commentary concerning this and similar issues—although less consideration generally has been given to their likely causes.
Where in the World Are the Workers? Cultural Underrepresentation in I-O Research
Authors: Myers Christopher G.
Published: March 2016

Few would dispute that the nature of work, and the workers who perform it, has evolved considerably in the 70 years since the founding of the Society for Industrial and Organizational Psychology (SIOP) as the American Psychological Association's (APA's) Division 14, focused on industrial, business, and organizational psychology. Yet, in many ways the populations sampled in industrial–organizational (I-O) psychology research have failed to keep pace with this evolution. Bergman and Jean (2016) highlight how I-O research samples underrepresent (relative to the labor market) low- or medium-skill workers, wage earners, and temporary workers, resulting in a body of science that is overly focused on salaried, professional managers and executives. Though these discrepancies in the nature of individuals’ work and employment are certainly present and problematic in organizational research, one issue that should not be overlooked is that of adequately representing nationality and culture in I-O research samples.
Examining Worker Underrepresentation in Selection Research: The Domain Matters
Authors: Huffcutt Allen H. , Culbertson Satoris S.
Published: March 2016

We concur with Bergman and Jean (2016) that worker samples tend to be underrepresented in organizational research, which could have deleterious effects on the conclusions and practices derived from this research. However, we argue that the effects of underrepresentation could vary considerably by organizational domain (e.g., selection vs. leadership vs. satisfaction). Our focus with this commentary is to address its effects on organizational selection, particularly with employment interviews, including issues such as criterion-related validity, prevalence of student samples, and the four criteria outlined by the focal authors (overlooked phenomena, differences in construct meaning, worker status, and human capital patterns).
View From the Trenches: Practitioners’ Perspectives on Key Issues and Opportunities in Low-Wage and Frontline Jobs
Authors: Sliter Michael , Holland Brent , Sliter Katherine , Jones Morgan
Published: March 2016

Bergman and Jean (2016) rightly argue that published research in industrial–organizational (I-O) psychology often underrepresents low-wage and frontline employees in favor of professional workers and management. One possible consequence of this bias is that I-O research may unintentionally marginalize workplace phenomena that impact employees professionally and personally. One example offered by Bergman and Jean is economic tenuousness, a work–life stressor that is more likely to be experienced by low-income and frontline employees. The recent growth in the proportion of individuals employed in low-wage jobs (Albelda & Carr, 2012) reinforces the need to explore the impact of the publication rift between the science and practice of I-O psychology.
Answer: They're Everywhere and We Know Quite a Bit About Them
Authors: Vanhove Adam J.
Published: March 2016

Bergman and Jean (2016) suggest that an underrepresentation of nonmanagerial workers in industrial and organizational (I-O) research is hindering our contribution to practice and ultimately our legitimacy as a discipline. I agree with the target article authors’ overarching message insomuch as it serves as a reminder that we, as I-O psychologists, have responsibilities to understand and improve the work experience of a diverse range of populations. However, I also believe the authors’ claim that nonmanagerial workers are underrepresented may be overstated. Moreover, I offer a perspective suggesting that the current supply of research being produced in the name of I-O psychology is driven by real world demand, that this naturally occurring phenomenon is what maximizes our impact on practice, and that ignoring this phenomenon is actually what hinders the legitimacy of applied disciplines.
Sample Adequacy and Implications for Occupational Health Psychology Research
Authors: Michel Jesse S. , Hartman Paige , O'Neill Sadie K. , Lorys Anna , Chen Peter Y.
Published: March 2016

Bergman and Jean (2016) skillfully summarize how the industrial and organizational (I-O) psychology literature generally overrepresents salaried, core, managerial, professional, and executive employees. We concur that that the underrepresentation of traditional workers (i.e., wage earners, laborers, first-line personnel, freelancers, contract workers, and other workers outside managerial, professional, and executive positions) can negatively affect our science. In our commentary we extend the arguments of Bergman and Jean by (a) discussing the appropriate use of samples, which are determined by study goals and hypotheses, and (b) further examining samples in occupational health psychology (OHP) and related journals, which generally require worker samples.
The Importance of Sample Composition Depends on the Research Question

Bergman and Jean (2016) compare published industrial and organizational (I-O) literature with labor statistics, demonstrating an underrepresentation of “workers” (i.e., “wage earners, laborers, first-line personnel, freelancers, contract workers”) relative to managerial, professional, and executive positions. They note that one of four ways in which worker underrepresentation undermines the utility of I-O psychology research is that we could miss the role of worker status as a main effect on important variables and/or a moderator of key relationships, which could hinder understanding of important phenomena as they relate to workers. We applaud the emphasis on workers and agree with this basic premise.
Solute dispersion in pulsatile Casson fluid flow in a tube with wall absorption

The analysis of axial dispersion of solute is presented in a pulsatile flow of Casson fluid through a tube in the presence of interfacial mass transport due to irreversible first-order reaction catalysed by the tube wall. The theory of dispersion is studied by employing the generalized dispersion model proposed by Sankarasubramanian & Gill (Proc. R. Soc. Lond. A, vol. 333 (1592), 1973, pp. 115–132). This dispersion model describes the whole dispersion process in terms of three effective transport coefficients, i.e. exchange, convection and dispersion coefficients. In the present study, the effects of yield stress of Casson fluid ${\it\tau}_{y}$, wall absorption parameter ${\it\beta}$, amplitude of fluctuating pressure component $e$ and Womersley frequency parameter ${\it\alpha}$ on the dispersion process are discussed under the influence of pulsatile pressure gradient. In a pulsatile flow, the plug flow radius changes during the period of oscillation and it has an effect on the dispersion process. Even with the Casson fluid model also, in an oscillatory flow, for small values of ${\it\alpha}$, the dispersion coefficient $K_{2}$ is positive, but when the value of ${\it\alpha}$ is as large as 3, $K_{2}$ takes both positive and negative values due to the fluctuations in the velocity profiles. This nature becomes more predominant for ${\it\tau}_{y}$, $e$ and ${\it\beta}$. It is observed that initially, for small time, the amplitude and magnitude of fluctuations of $K_{2}$ becomes more rapid and increases with time but it decreases after certain time and reaches a non-transient state for large time. Like in the case of Newtonian model, double frequency period for $K_{2}$ is observed at small time for large values of ${\it\alpha}$ with the Casson model for blood. It is seen that critical time for which $K_{2}$ reaches a non-transient state is independent of ${\it\tau}_{y}$ and $e$ but is dependent on ${\it\alpha}$. It is also observed that the axial distribution of mean concentration $C_{m}$ of solute depends on ${\it\tau}_{y}$ and ${\it\beta}$. But the effect of $e$ and ${\it\alpha}$ on $C_{m}$ is not very significant. This dispersion model in non-Newtonian pulsatile flow can be applied to study the dispersion process in the cardiovascular system and blood oxygenators.
On turbulent particle fountains
Authors: Mingotti Nicola , Woods Andrew W.
Published: March 2016

We describe new experiments in which particle-laden turbulent fountains with source Froude numbers $20>Fr_{0}>6$ are produced when particle-laden fresh water is injected upwards into a reservoir filled with fresh water. We find that the ratio $U$ of the particle fall speed to the characteristic speed of the fountain determines whether the flow is analogous to a single-phase fountain ($U\ll 1$) or becomes a fully separated flow ($U\geqslant 1$). In the single-phase limit, a fountain with momentum flux $M$ and buoyancy flux $B$ oscillates about the mean height, $h_{m}=(1.56\pm 0.04)M^{3/4}B^{-1/2}$, as fluid periodically cascades from the maximum height, $h_{t}=h_{m}+{\rm\Delta}h$, to the base of the tank. Experimental measurements of the speed $u$ and radius $r$ of the fountain at the mean height $h_{m}$, combined with the conservation of buoyancy, suggest that $Fr(h_{m})=u(g^{\prime }r)^{-1/2}\approx 1$. Using these values, we find that the classical scaling for the frequency of the oscillations, ${\it\omega}\sim BM^{-1}$, is equivalent to the scaling $u(h_{m})/r(h_{m})$ for a fountain supplied at $z=h_{m}$ with $Fr=1$ (Burridge & Hunt, J. Fluid Mech., vol. 728, 2013, pp. 91–119). This suggests that the oscillations are controlled in the upper part of the fountain where $Fr\leqslant 1$, and that they may be understood in terms of a balance between the upward supply of a growing dense particle cloud, at the height where $Fr=1$, and the downward flow of this cloud. In contrast, in the separated flow regime, we find that particles do not reach the height at which $Fr=1$: instead, they are transported to the level at which the upward speed of the fountain fluid equals their fall speed. The particles then continuously sediment while the particle-free fountain fluid continues to rise slowly above the height of particle fallout, carried by its momentum.
Transcultural Aesthetics and Postcolonial Memory: the Practices and Politics of Remembering in Tan Twan Eng’sThe Garden of Evening Mists
Authors: Poon Angelia
Published: March 2016

The tension between the use of postcolonial memory to bear witness to the past and the aestheticization of memory lies at the center of Malaysian-born writer Tan Twan Eng’s second novel,The Garden of Evening Mists(2012), a work that features the Japanese occupation of Malaya during World War II and the postwar period of the Malayan Emergency. The main protagonist is a former judge named Yun Ling who, faced with the prospect of eventual memory and speech loss, is moved to record her past experiences including the time she was a prisoner of war interred and when she was an apprentice to the gardener, Aritomo. In this article, I examine the novel’s self-conscious musings about the nature of memory and the ways in which memory may be represented and preserved. Tan’s novel attempts to provide a meditation on the transcultural mediation and aestheticization of memory by deliberately intermingling and overlaying various cultural features, artistic traditions and ethno-cultural subjectivities when it comes to processes of remembering. The attempt to transculturally aestheticize memory is on one level a metafictional and ostensibly inclusive move to affirm the plurality of stories and multiple perspectives. Yet, this is undermined by the novel’s very strategies of aestheticization, which run the risk of making memory an artistic object so “precious” and rarefied as to counter the more avowedly political function of memory—that of bearing witness to history.
SAVARIC, GLASTONBURY AND THE MAKING OF MYTHS: A REAPPRAISAL
Authors: Stout Adam
Published: March 2016

Historians have long been aware that the vicious feud between the monastery of Glastonbury and its bishop in the early thirteenth century was responsible for turning Glastonbury’sscriptoriuminto the most astonishing and inventive manufacturer of forged documents. In what Julia Crick has memorably termed ‘the marshalling of antiquity’, new documents were produced and older ones annotated, all tending to demonstrate the antiquity of Christian Glastonbury, and its right to self-government and autonomy, free from external interference. The monastery’s chroniclers were equally partisan, but historians and archaeologists alike have tended to accept their account of Glastonbury’s more recent history at face value. Correcting the chroniclers’ anti-Savaric bias allows for some fresh thinking on the construction of both the Glastonburymythosand of the abbey building itself. It also raises questions about the remarkable reverence with which scholars continue to treat Glastonbury’s ancient texts.
Flashes of Trading Intent at NASDAQ

We use the introduction and subsequent removal of the flash-order functionality from NASDAQ as a natural experiment to investigate the impact of voluntary disclosure of trading intent on market quality. We find that flash orders significantly improve liquidity in NASDAQ. Furthermore, overall market quality improves (deteriorates) when flash functionality is introduced (removed). This result can be attributed to increased competition among liquidity suppliers across competing trading venues. Alternatively, flash orders attract responses from reactive traders immediately after the announcement, attracting more “hidden liquidity” and lowering risk-bearing costs for the overall market.
Implicit role of Cairns distributed ions and weak relativistic effects of electrons in the formation of dust acoustic waves in plasma
Authors: Kalita Bhaben Chandra , Kalita Rekha
Published: March 2016

In this model of a dusty plasma, we have investigated dust acoustic waves consisting of electrons with weak relativistic effects, Cairns distributed cold ions and negatively charged mobile dust. Dust acoustic (DA) compressive and rarefactive solitons of various amplitudes are established. The parameter ${\it\beta}$ involved in Cairns distribution is related to the non-thermal parameter ${\it\alpha}$. However, the increase of ${\it\beta}$, which is independent of temperature, becomes instrumental for complete linear increase or decrease of the amplitudes of both the compressive and rarefactive relativistic solitons. Hence it is worthwhile to note that the increase of ${\it\beta}$ is solely due to the rest energy and not due to kinetic energy in this relativistic plasma. This is one of the most significant results of our investigation. Also, the flux of negative charges from the dust particles, together with the effect of the relativistic electrons, appears to balance the positive charges of Cairns distributed ions for nearly constant growth of amplitudes.
