Mechanical and thermal properties of glass fiber–vinyl ester resin composite for pipeline repair exposed to hot-wet conditioning
Authors: Shamsuddoha Md , Djukic Luke P , Islam Md Mainul , Aravinthan Thiru , Manalo Allan
Published: July 2016

Fiber-reinforced composites are a well-recognized option for repair and rehabilitation of the pipelines for the oil and gas industry. Infilled composite sleeve system provides an effective rehabilitation solution, where the sleeve acts as prime reinforcement without any direct contact with steel. However, the long-term performance of the repair is dependent, in part, on the effect of hygrothermal ageing of the composites. In this publication, glass transition temperature and mechanical properties are compared for glass-fiber reinforced vinyl ester composite, both as-manufactured and after hot-wet conditioning at 80℃. The tensile and shear strength reduced substantially during conditioning, whilst the elastic modulus was relatively stable. The average glass transition temperature of the composite dropped from the as-manufactured value of 110℃ to 97℃ and 101℃, after 1000 and 3000 h of conditioning, respectively, indicating that it is stable and that the composite is suitable for use as a pipeline repair material operating at 80℃. The results indicate that a 1000 h conditioning period, specified as a minimum period in ISO/TS 24817 is suitable for representing long-term properties for stiffness-based designs for the composite material and conditioning temperature investigated.

It is well known that exposure to maternal separation (MS) in early life causes plastic changes in the nervous system in adulthood, occasionally resulting in ubiquitous chronic pain. However, the pathogenic mechanisms of pain hypersensitivity remain unclear. Here, the authors examined the involvement of corticosterone in orofacial mechanical hypersensitivity induced by MS. To establish a rat model of MS, pups were placed in isolated cages 180 min/d and kept in a temperature-controlled environment at 22 ± 2 °C for 14 d. Mechanical allodynia in the whisker pad skin in adulthood was induced by MS and was significantly suppressed by successive postnatal subcutaneous administration of the glucocorticoid receptor antagonist mifepristone. Corticosterone levels were increased in the serum of MS rats, and successive postnatal administration of subcutaneous corticosterone to naive rats induced mechanical allodynia in the whisker pad skin. The number of P2X3 receptor-immunoreactive (P2X3R-IR) trigeminal ganglion (TG) neurons innervating the whisker pad skin was significantly increased in MS rats and decreased following subcutaneous administration of mifepristone. The number of P2X3R-IR TG neurons innervating the whisker pad skin was also significantly increased following successive postnatal administration of subcutaneous corticosterone in naive rats. Moreover, the mechanical allodynia was suppressed 30 min after administration of the P2X3R antagonist A317491 to the whisker pad skin in MS rats. These findings suggest that the increase in P2X3R-IR TG neurons innervating the whisker pad skin via enhanced neonatal corticosterone signaling by MS plays an important role in orofacial mechanical allodynia in adulthood.

Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or bracing or thrusting of the mandible. Recent advances have clarified the relationship between gastroesophageal reflux and sleep bruxism (SB). However, the influence of pharmacological elimination of gastric acid secretion on SB has not been confirmed. The authors aimed to assess the efficacy of a proton pump inhibitor (PPI) on SB and to examine the gastrointestinal (GI) symptoms and endoscopic findings of the upper GI tract in SB patients. The authors performed a randomized double-blind placebo-controlled crossover study at Kagoshima University Hospital. Twelve patients with polysomnography (PSG)–diagnosed SB underwent an assessment of GI symptoms using the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) and esophagogastroduodenoscopy. At baseline (i.e., before interventions), the mean frequencies of electromyography (EMG) bursts and rhythmic masticatory muscle activity (RMMA) episodes were 65.4 ± 49.0 bursts/h and 7.0 ± 4.8 episodes/h, respectively, and at least 1 RMMA episode with grinding noise was confirmed in all participants. The mean FSSG score was 8.4 ± 5.6, and 41.7% of patients were diagnosed with gastroesophageal reflux disease. Mild reflux esophagitis was confirmed in 6 patients. PSG, including EMG of the left masseter muscle and audio-video recording, was performed on days 4 and 5 of administration of 10 mg of the PPI (rabeprazole) or placebo. PPI administration yielded a significant reduction in the frequency of EMG bursts, RMMA episodes, and grinding noise. No significant differences were observed regarding the swallowing events and sleep variables. Since the clinical application of PPI for SB treatment should remain on hold at present, the results of this trial highlight the potential application of pharmacological gastroesophageal reflux disease treatment for SB patients. Larger scale studies are warranted to corroborate these findings. (UMIN Clinical Trials Registry: UMIN000004577).
An efficient method for density measurement for high-tightness woven fabrics
Authors: Zhang Jie , Pan Ruru , Wang Jingan , Gao Weidong , Han Yaobin
Published: July 2016

To measure the warp and weft densities of high-tightness fabrics, an efficient inspection method utilizing a novel density–texture formulation is developed. The density–texture relationship of twill and satin weaves is analyzed, and a formulation based on the weft and wale densities is developed and applied to calculate the warp density. In the experiment, the weft and wale densities are detected using a projection method on separately acquired transmittance images, and the warp density is calculated using the density–texture formulation. Experimental results proved that the proposed method is effective for measuring yarn densities of high-tightness fabrics with twill and satin weaves under realistic production conditions and can satisfy the requirement for production practice.
Spacer fabric-based exuding wound dressing – Part I: Structural design, fabrication and property evaluation of spacer fabrics
Authors: Yang Yadie , Hu Hong
Published: July 2016

Exuding wound dressing is used to help wound healing. Currently, commercial dressings for heavily exuding wounds still have some drawbacks, such as poor integrity, poor air permeability, low water vapor transmission, and the need for a secondary dressing on the top. To overcome these drawbacks, a new type of wound dressing based on the three-layer spacer fabric structure is proposed in this study. The study includes two parts. The first part focuses on the design, fabrication, and property evaluation of spacer fabrics that can be used for wound dressing. Twelve different types of spacer fabrics were first fabricated. Then, different properties, including wettability, absorbency, permeability, and thermal insulation, were tested and evaluated. A statistical analysis was also conducted to evaluate the effects of structural and yarn parameters on the properties of the spacer fabrics. Based on the testing results, two suitable spacer fabrics were finally selected as the basis for wound dressing material. It is expected that this study could promote the application of spacer fabrics in the medical area.
A novel method for natural dyeing of cotton fabrics with anthocyanin pigments from Morus rubra fruits
Authors: Wang Huayin , Hussain Munir , Zhou Wenlong
Published: July 2016

A novel pathway to improve the substantivity of anthocyanin pigments from Morus rubra fruits onto cotton fabrics is proposed by preparing and applying an anionic agent (sodium, 4-(4,6-dichloro-1,3,5-triazinylamino)-benzenesulfonate) to fabrics. Successful modification of cotton fabrics with few negative effects was carried out and evidenced by the results of Fourier transform infrared spectroscopy, tensile strength and the whiteness index. The optimum amount of anionic agent was identified to be about 70 mg/g under the following conditions: 20% (owf) anionic agents, 1:20 material-to-liquor ratio, 100 g/L sodium sulfate, 30℃ for 60 min and pH 11.0. A temperature of 40℃ and a time of 60 min were found to be the optimal conditions for cotton fabrics dyeing with anthocyanin pigments. Dyed cotton fabrics had a shade of brilliance and saturation red with acceptable fastnesses for potential commercial applications. The influences of pH and temperature on the stabilities of the extracts were also investigated.
A Coasian perspective on informal rights assignment among waste pickers in the Philippines
Authors: Chua Mark Hansley
Published: July 2016

This paper examines in light of the Coase Theorem how delineation of a degree of enforceable rights for a previously open-access dumpsite in the Philippines would affect market transactions of waste pickers. It shows that a simplistic exclusion solution was not enough to constrain rent dissipation of recyclables in the primeval land fill. Some intervention of non-government organisations backed by some initial government assistance were found helpful in reducing transaction costs to sustain operations and promote innovations and initiatives from the scavengers themselves despite obvious external economic difficulties.
Protest in the city: Urban spatial restructuring and dissent in New York, 1960–2006
Authors: Rafail Patrick
Published: July 2016

Accessible space is a necessary component of urban protest. Little research, however, has examined the spatial evolution of protest activity over time. Much of the existing research emphasises the legal right to protest, however, less effort has been made to examine how micro-contexts may facilitate or impede dissent. This research focuses on how the built environment of cities can serve as either attractors or detractors of protest using a unique geocoded sample of 6217 protest events taking place in New York City between 1960 and 2006. I use a spatial count model to examine the relationship between the built environment and protest intensity. The results point to significant shifts in where protests have occurred over time. Protests become increasingly spatially concentrated, with a disproportionate amount of activism taking place on or in close proximity to privately owned public spaces. Spaces in close proximity to powerful organisational or institutional targets also experience heightened protest activity. Overall, I show that the built environment, and the social relationships creating it, powerfully influence where dissent occurs. This is consistent with the advent of neoliberal policies directing urban spatial restructuring, which have brought about a process of structural funnelling for protest, ultimately making events more likely to occur in spaces that are hostile to mobilisation.
Child Deprivation in Gujarat
Authors: Chaurasia Aalok Ranjan
Published: July 2016

This article analyses the deprivation faced by children below five years of age in Gujarat, one of the most economically developed states of India, on the basis of a child deprivation index that has been constructed for the purpose. The analysis reveals that the deprivation faced by the children of the state is quite pervasive and there are significant within state variation with the situation appearing alarming in some districts. The analysis calls for a district-based approach of addressing the deprivation faced by the children of the state with a focus on building the capacity of women.
Everyday Deeds: Enactive Protest, Exit, and Silence in Deliberative Systems
Authors: Rollo Toby
Published: July 2016

The deliberative systems approach is a recent innovation within the tradition of deliberative democratic theory. It signals an important shift in focus from the political legitimacy produced within isolated and formal sites of deliberation (e.g., Parliament or deliberative mini-publics), to the legitimacy produced by a number of diverse interconnected sites. In this respect, the deliberative systems (DS) approach is better equipped to identify and address defects arising from the systemic influences of power and coercion. In this article, I examine one of the least explored and least understood defects: the exclusion of non-speaking political actors generated by the uniform privileging of speech in all sites within a system. Using the examples of prefigurative protest, Indigenous refusal to deliberate, and the non-deliberative agency of disabled citizens, I argue that the DS approach allows theorists to better understand forms of domination related to the imposition of speech on those who are either unwilling or unable to speak.
Harm Reduction From Below
Authors: Van Schipstal Inge , Mishra Swasti , Berning Moritz , Murray Hayley
Published: July 2016

This article focuses on how recreational drug users in the Netherlands and in online communities navigate the risks and reduce the harms they associate with psychoactive drug use. To do so, we examined the protective practices they invent, use, and share with their immediate peers and with larger drug experimenting communities online. The labor involved in protective practices and that which ultimately informs harm reduction from below follows three interrelated trajectories: (1) the handling and sharing of drugs to facilitate hassle-free drug use, (2) creating pleasant and friendly spaces that we highlight under the practices of drug use attunements, and (3) the seeking and sharing of information in practices to spread the good high. We focus not only on users’ concerns but also on how these concerns shape their approach to drugs, what young people do to navigate uncertainties, and how they reach out to and create different sources of knowledge to minimize adversities and to improve highs. Harm reduction from below, we argue, can best be seen in the practices of sharing around drug use and in the caring for the larger community of drug-using peers.
Sexually Objectifying Pop Music Videos, Young Women’s Self-Objectification, and Selective Exposure: A Moderated Mediation Model
Authors: Karsay Kathrin , Matthes Jörg
Published: July 2016

There is intense discussion among experts about the potential negative impact of sexually objectifying media content on young women. This article presents an experimental study in which young women were either exposed to pop music videos high in sexual objectification or to pop music videos low in sexual objectification. Women’s self-objectification and their subsequent media selection behavior were measured. The results indicate that exposure to sexually objectifying media increased self-objectification, which in turn increased the preference for objectifying media content. Self-esteem, the internalization of appearance ideals, and body mass index (BMI) did not influence these relationships. Implications of these findings are discussed.
Robust supervisory control policy for automated manufacturing systems with a single unreliable resource
Authors: Luo Jianchao , Xing Keyi , Wu Yunchao
Published: July 2016

Over the past two decades, the development of supervisory controllers that guarantee deadlock-free operation for automated manufacturing systems (AMSs) has been an active area of research. Most work to date assumes that the system resources are reliable. This paper focuses on the robust supervisory control problem of AMSs with a single unreliable resource. Our objective is to develop a robust supervisory control policy under which the system can continue producing in the face of the unreliable resource’s failure or recovery. To do so, we integrate an optimal deadlock avoidance policy based on a Petri net with a modified Banker’s Algorithm and present a novel robust supervisory control policy. It is proven to be of polynomial complexity and more permissive than two existing policies. Also, experimental results on a set of AMSs generated randomly indicate its superiority over all other existing policies.
Finite time attitude tracking control of an autonomous airship
Authors: Wang Yueying , Zhou Pingfang , Chen Ji-An , Duan Dengping
Published: July 2016

The problem of station-keeping attitude tracking control for an autonomous airship with system uncertainties and external disturbances is investigated. Adaptive laws are applied to estimate the upper bounds of uncertainties and disturbances, and a nonlinear finite time control scheme is proposed by combing input/output feedback linearization with integral sliding mode technique. Different from the existing works on attitude control of airship, the developed controller can guarantee the yaw, pitch and roll angle trajectories track the desired attitude in finite time in spite of uncertain system uncertainties and external disturbances. Simulation results are provided to illustrate the attitude tracking performance.
Adaptive prescribed performance sliding mode control of MEMS gyroscope
Authors: Lu Cheng , Fei Juntao
Published: July 2016

An adaptive prescribed performance sliding mode control (APPSMC) of Micro-Electro-Mechanical System gyroscopes is proposed for the trajectory tracking in the presence of parameter variations and external disturbances. Steady-state error, transient error and convergence rate are important performance indexes in gyroscope systems. However, these indexes have not been investigated and corresponding control methods are not investigated as well. The proposed APPSMC scheme can guarantee that the tracking error is strictly within a predefined performance bound and the convergence rate is no less than a predefined value. All the gyroscope parameters including the angular velocity can be correctly estimated by adaptive laws and the disturbance bound is estimated by a neural network estimator to alleviate the chattering problem. Simulation results demonstrate the effectiveness of the proposed adaptive prescribed performance sliding mode controller.
Sliding mode based fractional-order iterative learning control for a nonlinear robot manipulator with bounded disturbance
Authors: Ghasemi Iman , Ranjbar Noei Abolfazl , Sadati Jalil
Published: July 2016

In this paper a new type of sliding mode based fractional-order iterative learning control (ILC) is proposed for nonlinear systems in the presence of uncertainties. For the first time, a sliding mode controller is combined with fractional-order ILC. This sliding mode based [Formula: see text] and [Formula: see text]-type ILC is applied on a nonlinear robot manipulator. Convergence of the proposed method is investigated when the stability is also proved. In this method, the control signal at any iteration is generated in two parts. The first section comes from the sliding mode controller while the second part is output of the fractional-order ILC. The latter signal is assessed using its previous amount and the sliding mode error signal. The achieved control law is capable of controlling nonlinear iterative processes, perturbed by bounded disturbances with high accuracy. The same frequent disturbance is eliminated by the iterative learning part, while the effect of nonrepetitive uncertainty is improved by the sliding mode part. The sliding mode based [Formula: see text]-type ILC (as an adaptive control law) is proposed to control a single-link arm robot. The controller is then improved to sliding mode based [Formula: see text]-type ILC. The effectiveness of the proposed method is again investigated on a single-link robot manipulator through a simulation approach. It is shown that the controller for [Formula: see text] provides performance by means of faster response together with more accuracy with respect to a conventional ILC.
Which emotional profiles exhibit the best learning outcomes? A person-centered analysis of students’ academic emotions
Authors: Ganotice Fraide A. , Datu Jesus Alfonso D. , King Ronnel B.
Published: July 2016

Previous studies on academic emotions have mostly used variable-centered approaches. Although these studies have elucidated the relationships between academic emotions and key academic outcomes, they cannot identify naturally-occurring groups of students defined by distinct academic emotion profiles. In this study, we adopted a person-centered approach to explore whether students can be grouped in terms of distinct academic emotion profiles and whether these groups differed in terms of key academic outcomes. Cluster analyses showed four distinct profiles across both domain-general (Study 1) and domain-specific (Study 2) academic emotions. Students with high levels of positive academic emotions and low levels of negative academic emotions exhibited the most adaptive educational outcomes followed by students characterized by high levels of positive emotions and moderately high levels of shame. The most maladaptive profile was exhibited by students who are low in positive academic emotions and high in negative academic emotions. Theoretical and practical implications are discussed.

Published: July 2016

The present study was designed to understand differences between unaccompanied refugees who retained or achieved good mental health ( healthy or resilient) and those who maintained or developed poor mental health ( clinical and vulnerable). Using person-based analyses, the role of pre-migration traumatic exposure and acculturation-related factors in long-term trajectories of psychological adjustment among unaccompanied refugees was explored. This study included three waves of data collection in a population-based sample. The participants were 918 unaccompanied refugees who had received asylum and residence status in Norway. The pattern of change in depression symptoms over time was used to characterize subgroups displaying resilient, vulnerable, clinical or healthy trajectories. Results indicated that the extent of post-migration acculturation hassles and heritage culture competence, as well as pre-migration traumatic events and gender, distinguished the refugee groups in terms of mental health trajectories. The implications for clinical practice and immigration policy are discussed.
Trusted to Deceive: A Case Study of ‘Strategic Deception’ and the Normalization of Lying at Work
Authors: Jenkins Sarah , Delbridge Rick
Published: July 2016

Lying is an endemic feature of social life but has remained under-researched in organization studies. This paper examines the case of VoiceTel, a market leader in the high-quality virtual reception business that practised ‘strategic deception’ (Patwardhan et al., 2009). Receptionists concealed that they were not physically located in their clients’ premises and lying was an intrinsic and enduring feature of their work. We adapt and extend Ashforth and Anand’s (2003) ‘normalization of corruption’ framework to develop a new model of the ‘normalization of lying’. We examine how lying becomes institutionalized, rationalized and socialized into the structure and culture of an organization such that it becomes embedded, maintained and strengthened over time as a legitimate and integral part of the job. Our model of normalization integrates organizational and group levels to examine the significance and interaction of ‘bottom-up’ as well as ‘top-down’ processes. Employees gained recognition from their proficiency in deception and drew considerable satisfaction, self-esteem and status as employees who are ‘trusted to deceive’.
Identity Paradoxes: How Senior Managers and Employees Negotiate Similarity and Distinctiveness Tensions over Time
Authors: Cuganesan Suresh
Published: July 2016

Employee identity is shaped by a need to feel similarity to, as well as distinctiveness from, others in organizations. While this paradoxical tension is important we know little about how it is managed over time, especially when senior managers prioritize one element of the paradox over the other. Consequently I investigate how senior managers and employees negotiate the similarity–distinctiveness identity paradox over time, doing so through a longitudinal case study of a police organization undergoing change. The study contributes to prior paradox literature in two significant ways. First, it reveals how senior managers and employees negotiate tensions in employee identity between similarity and distinctiveness as an emergent and cyclical process of identity regulation and heterogeneous identity work. This shows how the balance between similarity and distinctiveness is both elusive to achieve for all organizational participants and difficult to sustain over time. Second, it highlights how defensive approaches to identity paradox may lead to positive outcomes, with this contingent on organizational participants’ ability to make strong claims about the importance of the paradox element they favour for the organization’s future.
The Interplay between Intuition and Rationality in Strategic Decision Making: A Paradox Perspective
Authors: Calabretta Giulia , Gemser Gerda , Wijnberg Nachoem M.
Published: July 2016

Both intuition and rationality can play important roles in strategic decision making. However, a framework that specifically accounts for the interplay between intuition and rationality is still missing. This study addresses this gap by using a paradox lens and conceptualizes the intuition–rationality duality as a paradoxical tension. We draw on seven case studies of innovation projects to empirically derive a three-step process for managing this intuition–rationality tension through paradoxical thinking. Our empirical data suggest that management of the tension starts with preparing the ground for paradoxical thinking by creating managerial acceptance for the contradictory elements of rational and intuitive approaches to decision making. The process then continues by developing decision-making outcomes through the integration of intuitive and rational practices. Finally, the outcomes of paradoxical thinking are embedded into the organizational context. For each step of the model, we indicate a set of practices that, by leveraging intuitive or rational characteristics of decision making, practitioners can use to deal with this cognitive tension in the different steps of our model.
In the Shadows of Time: A Case Study of Flexibility Behaviors in an Interorganizational Project
Authors: Ligthart Rik , Oerlemans Leon , Noorderhaven Niels
Published: July 2016

We use a longitudinal examination of the production of a complex vessel to develop theory concerning operational flexibility behaviors within interorganizational projects. We find that operational flexibility behaviors are enabled by trust between project participants, sense of urgency, and the availability of resources. These enablers are in turn positively influenced by positive experiences in previous interactions (“shadow of the past”) and expectations of possible future collaboration (“shadow of the future”), the temporary nature of interorganizational projects and slack in project tasks, respectively. The positive effect of enablers on operational flexibility is weakened by the time pressure project participants experience. The latter is also caused by the temporariness of interorganizational projects. Based on our findings, we propose that the different time dimensions play a crucial role in explaining flexibility behaviors in interorganizational projects: the temporariness that is an essential characteristic of interorganizational projects has two potentially opposite effects on the behavior of its participants, and we argue that shadows of the past and future play a decisive role in which of the two effects will dominate. The theoretical framework based on our case study suggests that the temporariness of interorganizational projects is indeed important—as acknowledged in the literature—but that its effect is contingent on shadows of past and future.
Clash of the Titans: Temporal Organizing and Collaborative Dynamics in the Panama Canal Megaproject
Authors: van Marrewijk Alfons , Ybema Sierk , Smits Karen , Clegg Stewart , Pitsis Tyrone
Published: July 2016

Recent studies of temporary organizing and project-based work explain how organizational actors establish and maintain clear role structures and harmonious relations in the face of precariousness by engaging in stabilizing work practices. This focus upon ‘order’ undervalues conflict-ridden negotiations and power struggles in temporary organizing. This paper demonstrates that in temporary organizing conflict and order may exist in tandem. Drawing close to the collaborative dynamics in a large-scale global project, we analyse the political struggles over role patterns and hierarchic positioning of client and agent in the temporary organization of the Panama Canal Expansion Program (PCEP). In such projects, the agent typically takes the position of project leader. In this case however, the client was formally in charge, while the agent was assigned the role of coach and mentor. The diffuse hierarchy triggered project partners to engage in both harmony-seeking social and discursive practices and to enter into conflict-ridden negotiations over authority relations in the everyday execution of the PCEP project. Our study contributes to existing literatures on temporal organizing by presenting a case of simultaneous practices of harmonization and contestation over mutual roles and hierarchic positions. We also show that studying collaboration between project partners involves, not merely analysing project governance structures, but also offering a context-sensitive account of everyday social and discursive practices. Finally, we reflect on a view of ‘permanence’ and ‘temporariness’ as themselves contested categories and symbolic sites for struggle.
To Continue or not to Continue? Drivers of Recurrent Partnering in Temporary Organizations
Authors: Ebers Mark , Maurer Indre
Published: July 2016

While research has provided ample evidence that temporal (dis-)continuity in partnering is highly consequential for the governance and performance outcomes of temporary organizations, we know much less about the conditions that drive the members of temporary organizations to engage in recurrent partnering. Focusing on project organizations, the present research offers theoretical arguments and related empirical evidence that illuminate when and why project-leading organizations expect to continue collaboration with the same project partner in future projects. Specifically, we show that expectations of recurrent collaboration are a function of backward-looking experiential learning and forward-looking opportunity cost assessments. Our findings contribute to better understanding of temporality in temporary organizations by uncovering a set of factors conducive to explaining when and why the same partners engage in temporary sequences of projects.
‘It Sends a Cold Shiver down my Spine’: Ghostly Interruptions to Strategy Implementation
Authors: Pors Justine Grønbæk
Published: July 2016

This paper offers new theoretical and empirical understanding of interruptions to strategy implementation by drawing attention to their ghostly nature. The paper proposes a theoretical framework for thinking about the ghostly by combining Freud’s concept of the uncanny with theorizing in cultural geography on collapses of linear time as well as with Avery Gordon’s sociological work on ghostly matters. Empirically, the paper examines the ghostly nature of strategy interruptions through a detailed analysis of conversations between middle managers at a strategy seminar in a Danish local government. I portray the uncanny moments where the familiar account of organizational purposes is not so self-evident anymore, but all of a sudden appears rather disturbing. I show how middle managers envision other, darker futures and express the feeling that something else, something different from before, must be done, although they cannot say exactly what. Going beyond previous accounts of strategy interruption, for example as deliberate resistance by middle managers, the paper contributes with new insight into the moments where the neat ordering of organizational realities performed by corporate strategies breaks down and middle managers come into contact with the broader social and political stakes of their work.
Naturalizing Gender through Childhood Socialization Messages in a Zoo
Authors: Garner Betsie , Grazian David
Published: July 2016

We draw on public observations conducted in a zoo to identify three instances in which adults make use of its specific spatial and symbolic resources to transmit socialization messages to children according to “naturalized” models of hegemonic gender difference. First, adults attribute gender to zoo animals by projecting onto them human characteristics associated with feminine and masculine stereotypes. Second, adults mobilize zoo exhibits as props for modeling their own normative gender displays in the presence of children. Third, adults discipline boys and girls differently in the context of the zoo’s built environment, and in doing so, they communicate socialization messages to children regarding how to behave in conventionally gendered ways. In emphasizing the context of the zoo as a site for the naturalization of gender categories, we identify how adults transmit gender socialization messages to children that promote gender stereotypes associated with the biological determinism of the natural living world.
Risk and Emotion Among Healthy Volunteers in Clinical Trials
Authors: Cottingham Marci D. , Fisher Jill A.
Published: July 2016

Theorized as objective or constructed, risk is recognized as unequally distributed across social hierarchies. Yet the process by which social forces shape risk and risk emotions remains unknown. The pharmaceutical industry depends on healthy individuals to voluntarily test early-stage, investigational drugs in exchange for financial compensation. Emblematic of risk in late modernity, Phase I testing is a rich site for examining how class and race shape configurations of emotion and risk. Using interview data from 178 healthy trial participants, this article examines emotion and risk as mutually constituting processes linked to biographical context and social structure. Biographical events like economic insecurity and incarceration influence how risk is felt by providing comparative experiences of felt risk and felt benefits. Such events, in turn, are structured by class-based and racial inequalities, linking class and race positions to primary emotional experiences of risk.
Civil disobedience and conscientious objection
Authors: Cooke Maeve , Petherbridge Danielle
Published: July 2016

The question of civil disobedience has preoccupied philosophical discourse at least since Thoreau's articulation of disobedience as a form of non-compliance and Rawls' classic definition outlined in the wake of the civil rights and student protest movements of the 1960s. It has become increasingly clear, however, that these classic definitions are being challenged and rethought from a variety of traditions in the wake of contemporary protests. These articles engage with the most recent debates surrounding civil disobedience and conscientious objection, opening up original new paths for thinking about forms of protest. They also reveal disagreements about how to understand civil disobedience and about the place of conscience in political protest, inviting further discussion on these questions and issues.
Preparation of High-quality Hematoxylin and Eosin–stained Sections from Rodent Mammary Gland Whole Mounts for Histopathologic Review
Authors: Tucker Deirdre K. , Foley Julie F. , Hayes-Bouknight Schantel A. , Fenton Suzanne E.
Published: July 2016

Identifying environmental exposures that cause adverse mammary gland outcomes in rodents is a first step in disease prevention in humans and domestic pets. “Whole mounts” are an easy and inexpensive tissue preparation method that can elucidate typical or abnormal mammary gland morphology in rodent studies. Here, we propose procedures to facilitate the use of whole mounts for histological identification of grossly noted tissue alterations. We noted lesions in mammary whole mounts from 14-month-old CD-1 mice that were not found in the contralateral gland hematoxylin and eosin (H&E)-stained section. Whole mounts were removed from the slide and carefully processed to produce high-quality histological sections that mirrored the quality of the original H&E-stained section in order to properly diagnose the unidentified gross abnormalities. Incorporation of this method into testing protocols that focus on human relevant chemical and endocrine disruptors exposure will increase the chances of identifying lesions in the gland and reduce the risk of false negative findings. This method can be especially invaluable when lesions are not always palpable during the course of the study or visible at necropsy, or when a single cross section of the mammary gland is otherwise used for detecting lesions.
Biopolitics, Thanatopolitics and the Right to Life
Authors: Nasir Muhammad Ali
Published: July 2016

This article focuses on the interrelationship of law and life in human rights. It does this in order to theorize the normative status of contemporary biopower. To do this, the case law of Article 2 on the right to life of the European Convention on Human Rights is analysed. It argues that the juridical interpretation and application of the right to life produces a differentiated governmental management of life. It is established that: 1) Article 2 orients governmental techniques to lives in order to ensure that both deprivation and protection of lives is lawful; 2) A proper application of Article 2 grounds itself on a proper discrimination of lives which causes Article 2 to be applied universally but not uniformly to all juridical subjects; 3) The jurisprudence of Article 2 is theoretically appreciable only in a ‘politics of life’. Finally, the article ends with a plea to analyse other fundamental human rights in the context of ‘biopolitical governmentality’.
Tibetan Diaspora, Mobility and Place: ‘Exiles in Their Own Homeland’
Authors: Vasantkumar Chris
Published: July 2016

This article elaborates a theoretical framework for making sense of Tibetans in Tibet who live as ‘exiles in their own homeland’. Placing questions of mobility at the centre of anthropological approaches to diaspora, it subjects ‘the fact of movement’ to critical scrutiny. In so doing it calls into question three fundamental assumptions of recent work in both ‘new mobilities’ and the study of diaspora more broadly: first, that people move and territory does not; second, that ‘place(s)’ and ‘movement(s)’ are different sorts of things, and clearly distinguishable; and, third, that movement takes places only in Euclidean space. Beginning by placing recent Tibetan experiences of exile and diaspora in comparative context, it then works through recent deconstructions of the boundary between movement and place, a critique of Western ethno-epistemologies of movement, and Law and Mol’s work on social topology as theoretical orientations that might allow us to make sense of mobile homelands and diasporas in situ.

This article suggests that Facebook embodies a new logic of capitalist governance, what has been termed the ‘social logic of the derivative’. The logic of the derivative is rooted in the now dominant financial level of the capitalist economy, and is mediated by social media and the algorithmic processing of large digital data sets. This article makes three precise claims: First, that the modus operandi of Facebook mirrors the operations of derivative financial instruments. Second, that the algorithms that Facebook uses share a genealogy with those of derivative financial instruments – both are outcomes of the influence of the ‘cyber sciences’ on managerial practice in the post-war years. Third, that the future potential of Facebook lies in its ability to apply the logic of derivatives to the financial valuation of ordinary social relations, thus further extending the process of financialization of everyday life.
High-growth firms in New Zealand: Superstars or shooting stars?
Authors: Satterthwaite Sara , Hamilton RT
Published: July 2016

This is an empirical study of the origin, demographics and fate of two cohorts of high-growth firms in New Zealand. Customised data on high-growth firms, covering 1125 and 1067 firms in the 2005 and 2008 cohorts, respectively, came from government sources. High-growth firms are smaller, more likely to emerge in service industries and grow through the creation of multiple separate establishments. The ability to sustain high-growth is independent of pre-growth age and employment size. High-growth firms have death rates up to four times greater than other contemporary firms, but the survivors do retain their employment size, continuing to contribute disproportionately to employment for some years beyond their initial high-growth phase. The demonstrated inability of high-growth firms to sustain high growth suggests a rethink on how ‘high growth’ is defined, with future research focusing on sustained growth firms.
The effect of ensemble and solo performance on affective experiences induced by music

Scherer and Zentner (2001) propose that affective experiences might be the product of a multiplicative function between structural, performance, listener, and contextual related features. Yet research on the effects of structure, and particularly texture, has mostly focused on perceived emotions. We therefore sought to test the effects of structural features on subjective musical experiences in a listening study by manipulating the performance, solo versus ensemble, of five segments of a piece for string quartet, while also exploring the impact of listener features such as musical training, listening habits and stable dispositions such as empathy. We found that participants ( N = 144, 78% female; Mage = 22.74 years, SD = 5.13) felt like moving more (ME) and perceived their physiological rhythms change more (VE) during ensemble compared to solo conditions. Moreover, ME significantly predicted positive emotions, such as Wonder and Power, while VE significantly predicted both positive and negative emotions, such as Tension and Nostalgia. We also found direct main and interaction effects of both segment and performance factors on all four emotion models. We believe these results support Scherer and Zentner’s model and show the importance of considering the interaction between compositional and instrumental texture when studying music-induced emotions.
If you’re happy and you know it: Music engagement and subjective wellbeing
Authors: Weinberg Melissa K. , Joseph Dawn
Published: July 2016

Experiencing and engaging with music have been fundamental to all societies across the ages. This study explores the connection between habitual music engagement and subjective wellbeing. Subjective wellbeing (SWB) comprises individual evaluations of life satisfaction, and is internationally regarded at policy and government levels. The present study uses data gathered in 2014 as part of the 31st survey of the Australian Unity Wellbeing Index to provide insight into the relationship between music engagement and SWB. A stratified random sample of 1,000 participants was interviewed via telephone. The findings revealed that engaging with music by dancing or attending musical events was associated with higher SWB than for those who did not engage with music in these forms. The findings also emphasised the important role of engaging with music in the company of others with regard to SWB, highlighting an interpersonal feature of music. The study provides an overview of the general relationship between music and SWB at a population level, by contrast to most research in the area that has focused on evaluating clinical interventions involving music. The insight gained from these findings can be used to inform future interventions and to better understand how music is involved in emotional regulation.
Multiple Past Concussions in High School Football Players

Background:

There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population.

Purpose:

To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale.

Results:

There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines).

Conclusion:

In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting.
