Ward-level leadership quality and prospective low-back pain of eldercare workers: do resident handlings mediate the association?
We investigated the extent to which ward-level leadership quality was associated with prospective low-back pain among eldercare workers, and how this association was mediated by observed resident handlings.
This research concerns the use of warped ruled surfaces in the load bearing structures of 19th century stone bridges in Prague. The descriptions of a skew arch used at The Negrelli Viaduct and a special surface called “corne de vache” used at The Legion Bridge are based not only on historical survey, archival materials and period publications, but also on contemporary measurements.
This contribution intends to shed light on the development of the rule of law, particularly by questioning the existence of such rule of law in early modern Amsterdam. In literature, thinner and thicker definitions are given, mostly presented as a continuum. This contribution will focus on mercantile customary law as it is a legal source that hardly fits in the literature-based categories. The importance of customary law seems to have decreased parallel with the bureaucratization of law; similarly this legal source can be considered as relatively democratic as it was based on the consent of a certain community. This ambiguity was also part of an old debate among legal historians.
Geopolymer concrete (GPC) was developed using one-part binders made from a mixture of waste clay brick (WCB) powder, fly ash, and slag in the precursor. Its suitability for use in rigid pavement construction was evaluated based on fresh properties, hardened properties, and durability characteristics. The effects of sealed and unsealed ambient curing and the size of the WCB particles on the strength of the GPC were also examined. Sealed ambient curing significantly increased the strength of the GPC, with longer sealing periods resulting in even stronger concrete. Sealing prevented water loss from the samples and reduced carbonation, protecting the concrete from microcracks caused by de...
This research presents a highly transparent concentrator photovoltaic system with solar spectral splitting for dual land use applications. The system includes a freeform lens array and a planar waveguide. Sunlight is first concentrated by the lens array and then reaches a flat waveguide. The dichroic mirror with coated prisms is located at each focused area at the bottom of a planar waveguide to split the sunlight spectrum into two spectral bands. The red and blue light, in which photosynthesis occurs at its maximum, passes through the dichroic mirror and is used for agriculture. The remaining spectrums are reflected at the dichroic mirror with coated prisms and collected by the long ...
“We’re not there yet” but it’s not “pie-in-the-sky”: Legal Consciousness, Decertification and the Equality Sector in England and Wales
Drawing on 38 in-depth, qualitative interviews, this article explores how people working in the equality sector in England and Wales view and use the current law around sex and gender, and how they imagine law’s future, particularly potential decertification, where the state would withdraw from certifying and regulating a person’s sex/gender. Whilst situated in the bureaucratic strand of the literature, the paper also contributes to wider legal consciousness studies. This literature has generally focused on people’s relationships to law in terms of domination, alienation and game-playing. Drawing on idioms and the language of touch, the paper unpacks the way in which equality actors t...
Wear Mechanisms of Cold-Sprayed Stellite-6 During Reciprocated Dry Sliding Under Different Sliding Speeds
Cobalt–chromium alloys are often employed in those environments that require reliable wear and friction properties. Cold Gas Dynamic Spray offers the opportunity to obtain good quality deposits of Stellite-6, that can be successfully used in harsh environments, where good surface performance, in terms of wear resistance, is required. It is also well-known that Stellite-6 is subjected to several physical changes at the interface during dry sliding, that are often related to the loading conditions. As a consequence, wear behavior of this alloy can undergo some variations that linear models are not able to capture, since micro-structural modifications occur during operation.
Wear monitoring method of water-lubricated polymer thrust bearing based on ultrasonic reflection coefficient amplitude spectrum
The water-lubricated thrust bearings of the marine rim-driven thruster (RDT) are usually composed of polymer composites, which are prone to serious wear under harsh working conditions. Ultrasonic is an excellent non-destructive monitoring technology, but polymer materials are characterized by viscoelasticity, heterogeneity, and large acoustic attenuation, making it challenging to extract ultrasonic echo signals. Therefore, this paper proposes a wear monitoring method based on the amplitude spectrum of the ultrasonic reflection coefficient. The effects of bearing parameters, objective function, and algorithm parameters on the identification results are simulated and analyzed. Taking th...

A response is needed to the numerous issues spurred by the expansion of the gig economy, where flexible patterns of employment prevail in contrast to permanent jobs. In this context of the exponential growth of the digital economy and underlying business models the largest nationwide study of its kind into the impact of the working conditions in the UK music industry 'Can Music Make You Sick?' has been conducted by MusicTank/University of Westminster. This research suggests the need to consider the future of work not only from an economic or employment law perspective but from a mental health one too. What are the psychological implications of precarious work and how are factors such ...
This paper aims at studying a generalized Camassa–Holm equation under random perturbation. We establish a local well-posedness result in the sense of Hadamard, i.e., existence, uniqueness and continuous dependence on initial data, as well as blow-up criteria for pathwise solutions in the Sobolev spaces Hs with s>3/2 for x∈R . The analysis on continuous dependence on initial data for nonlinear stochastic partial differential equations has gained less attention in the literature so far.
What are you reading? From core journals to trendy journals in the Library and Information Science (LIS) field
In this study, we present an objective, replicable methodology to identify trendy journals in any consolidated discipline. Trendy journals are those most read by authors who are currently publishing within the scope of the discipline. Trendy journal lists differ from consolidated lists of top core journals; the latter are very stable over time, mainly reflecting reputational factors, whereas the former reveal current influences not yet captured by studies based on bibliometric indicators or expert surveys. We apply our methodology to identify trendy journals among 167 titles indexed in the Web of Science category of the Information Science & Library Science (LIS) research area.
What Can Restructuring Laws Do? Geopolitical Shocks, the New German Restructuring Regime, and the Limits of Restructuring Laws
In this article, I discuss the possibilities and limitations of restructuring laws against the background of geopolitical shocks such as the Covid-19 pandemic and the current energy crisis. I make two claims, one narrow and focused on German bankruptcy law, and one broad with a cross-jurisdictional reach. My narrow claim relates to ‘StaRUG’, the new German restructuring regime. I argue that this law is a superfluous and flawed instrument. It should be repealed. My second claim is much broader. I argue that bankruptcy laws, including restructuring laws, are generally ill-suited to deal with the economic consequences of geopolitical or macroeconomic shocks as a ‘first line of defence’. ...
Many frameworks exist across the sciences and science-policy interface, but it is not always clear how they are developed or can be applied. It is also often vague how new or existing frameworks are positioned in a theory of science to advance a specific theory or paradigm. This article examines these questions and positions the role of frameworks as integral but often vague scientific tools, highlighting benefits and critiques. While frameworks can be useful for synthesizing and communicating core concepts in a field, they often lack transparency in how they were developed and how they can be applied.
Contemporary public discourse is saturated with speech that vilifies and incites hatred or violence against vulnerable groups. The term “hate speech” has emerged in legal circles and in ordinary language to refer to these communicative acts. But legal theorists and philosophers disagree over how to define this term. This paper makes the case for, and subsequently develops, the first corpus-based analysis of the ordinary meaning of “hate speech.” We begin by demonstrating that key interpretive and moral disputes surrounding hate speech laws—in particular, surrounding their compatibility with the rule of law, democracy, and free speech—depend crucially on the ordinary meaning of “hate s...
This open access book questions the stereotype depicting all Gulf (GCC) economies as not sustainable, and starts a critical discussion of what these economies and polities should do to guarantee themselves a relatively stable future. Volatile international oil markets and the acceleration of the energy transition has challenged the notion that oil revenues are sufficient to sustain oil economies in the near to medium term. But what is the meaning of economic sustainability? The book discusses the multiple dimensions of the concept: economic diversification, continuing value of resources, taxation and fiscal development, labor market sustainability, sustainable income distribution, env...
When is Disbelief Epistemic Injustice? Criminal Procedure, Recovered Memories, and Deformations of the Epistemic Subject
People can be treated unjustly with respect to the level of credibility others accord to their testimony. This is the core idea of the philosophical idea of epistemic justice. It should be of utmost interest to criminal law which extensively deals with normative issues of evidence and testimony. It may reconstruct some of the long-standing criticisms of criminal law regarding credibility assessments and the treatment of witnesses, especially in sexual assault cases. However, philosophical discussions often overlook the intricate complexities of real procedural law and its underlying considerations. In its present form, the philosophical notion of epistemic injustice provides limited i...
When nudges promote neutral behavior: an experimental study of managerial decisions under risk and uncertainty
Managers often make decisions in situations involving risk and uncertainty. To ensure the prosperity of the company, neutral behavior is desirable in such situations. However, when evaluating future-oriented managerial actions, cognitive biases can arise that are manifested as aversions towards risky and uncertain situations, leading to non-optimal decisions. In an online experiment with a convenience sample of 298 US participants, we investigate deviations from risk- and uncertainty-neutral managerial decisions and apply neutrality-promoting behavioral interventions in a business venture setting. We find that using a recommendation nudge before as well as after making an initial deci...
Respondeat superior is a legal doctrine conferring liability from one party onto another because the latter stands in some relationship of authority over the former. Though originally a doctrine of tort law, for the past century it has been used within the criminal law, especially to the end of securing criminal liability for corporations. Here, I argue that on at least one prominent conception of criminal responsibility, we are not justified in using this doctrine in this way. Firms are not answerable for the crimes committed by their employees, because firms cannot answer as to why the crime was committed; they lack the authority to offer the employee’s reasons for action. Though th...
