Trust in the Digital World The Return of the Kings of Old
No full textDrawing principally on examples and literature from the Anglosphere, the author argues that the high salience given to "trust" and "trustworthiness" in recent scholarly literature, and which (notably in Putnam's work) attributes declining trust to a widely mistrusted mass media does not acknowledge the trustbuilding potential (realised in some instances) of interactive "Web 2.0" applications. Drawing on O'Neill's proposal that trust inheres in dialogue and mutual checking and verification, the author argues that "Web 2.0" media provide a variety of instances where the "dialogic" character of "Web 2.0" has established and enhanced trustworthiness. He argues normatively for a combination of "Web 2.0" interactivity and the adoption and implementation of selfregulatory codes in order to enhance the trustworthiness of the media.trust, mass media, Web 2.0, self-regulation, trustworthiness.
Gaming market saturation and location growth potential: the case of Atlantic City
No full textCompeting casinos in Delaware, Pennsylvania, and New York State continue to erode revenues at Atlantic City’s casinos. Yet, recent evidence from nascent aspects of New Jersey gaming industry (sports betting and Internet gaming) suggest that the Atlantic City market might not be saturated. To assess whether the market is saturated or not, we first draw on the greater region’s casino gaming revenue history as well as county aggregate personal income and empirically derive the spatial extent of Atlantic City’s market. We then find a measure—regional gross gaming revenues (GGR) as a share of regional aggregate personal income—that suggests the market has been fairly saturated since at least 1990. We then apply two models—Huff’s and a time-series regression—to estimate impact of the addition of new casinos upon those in Atlantic City. Both suggest diminishing returns to scale of additional city slot machines upon the GGR within New Jersey. They also both show that new casinos in competing states would further erode Atlantic City’s share of regional GGR. This, of course, assumes that the greater economy continues apace

Erosion of sediment through cellular revetment blocks applied as slope protection along coasts and inland waterways
No full textErosion of banks and dikes subjected to water motion can be prevented, for instance by application of cellular concrete revetment blocks. This type of revetment combined the merits of a closed block revetment and a slope revetment consisting of loose materials. Advantages are high permeability, high stability against wave attack and low block weight. On top of this, cellular blocks are appealing because they allow the growth of vegetation. It is of vital importance that the granular material in the holes does not erode completely. Therefore physical model tests were carried out. The paper describes these tests and gives results.Steenzettinge
Predatory Publishers Threaten to Erode Scholarly Communication
No full textPredatory open-access (OA) publishers—the ones that exploit the gold (author pays)publishing model for their own profit—
threaten the reputation of rigorously peer-reviewed OA journals. Many OA advocates singularly champion the open
licensing of scholarly works but largely ignore the emerging serious quality issues. The result is an ever-increasing number of low-quality and even corrupt publishers, many of whom self-identify as noble for merely functioning as OA publishers—an identification that far too many OA advocates

Joint Tenancy with Right of Survivorship: A Legacy from Thirteenth Century England
No full textExamines joint tenancy with rights of survivorship in the thirteenth century. The author makes comparisons between thirteenth century and twentieth-century lawyers practicing in this area. The author analyzes joint tenancy today and the history of joint tenancy with rights of survivorship to show how family-oriented considerations can erode and change legal frameworks
Toward a Dignified Theory of Children: Prohibition of Collaborative Reproduction
No full textThis comment argues for the abolition of surrogacy agreements. The author maintains that such agreements are patently immoral, adversely affect the rights and interests of unborn children, and erode the value society places on the dignity of human life generally
High-Velocity Erosion of Sand
No full textDredging is the relocation of soil. Before the soil can be transported, it has to be loosened. This can be done hydraulically (jetting) or mechanically (cutting). Often, water jets are used to erode the soil layer. Over time, pickup functions have been derived to predict the amount of erosion corresponding to the flow conditions. However, existing pickup functions are inaccurate at high flow velocities. During the current study, erosion experiments have been done at high flow velocities (up to 4.7 m/s) corresponding to a bed shear stress of up to 60 Pa and a Shields parameter (θ) of up to 30. The results of these experiments were compared with a number of well-known data sets and pickup functions.

Dune erosion near sea walls; XBeach validation
No full textDuring a storm dunes erode and provide sediment to the beach. The foreshore rises and the wave height decreases. Subsequently the wave-induced water level setup increases. Seawalls do not erode. The waves in front of the seawall remain high throughout the storm and the wave-induced water level setup hardly changes. Over a dune-dike connection a water level gradient drives a current which transports sediment from the dunes to the seabed in front of the seawall. The loss of sediment to the dike causes the foreshore of dunes near the connection to rise slower resulting in more erosion. The amount of additional erosion near structures depends on the angle of wave incidence w.r.t. the shore. Dunes situated downstream of the connection experience a significant increases in erosion. Near the upstream connection sediment is deposited on the seabed in front of the structure. Sediment will pile up against the structure resulting in less erosion near the connection. The influence of structures on dune erosion was investigated in a series of experiments and were aimed at 4 different connections between a dune and a structure. Two configurations of dunes and structures were investigated with 2 different wave periods. In XBeach the erosion in a dike breach is a function of the breach width and the wave period. The erosion increases for a smaller breach width and an increasing wave period. XBeach underestimates the erosion above the dune revetment. The erosion in the revetment breach is predicted well. For experiments V1 & V3 the predictive capabilities of XBeach in dune sections are very good. The performance of XBeach for experiments V2 & V4 is relatively good. The effect of the wave period for 2DH models with a large depth scale (nd = 60) is not properly simulated by XBeach.Coastal MorphologyHydraulic EngineeringCivil Engineering and Geoscience
COVID-19 and Labour Law: Bosnia and Herzegovina
No full textIn this national report, the author presents an overview of the measures enacted to support the economy and govern the labour relations in Bosnia and Herzegovina in the wake of the COVID-19 pandemic. Measures are briefly discussed; the main findings are that they are skewed toward employers with the potential to erode employees’ rights and bargaining power
