The paper identifies and explores the solutions to certain underdeveloped and lacking legislative solutions and issues in the practice of the national data protection authority (CPDPA), which affect the aims of effective GDPR enforcement and transparency. On a broader level it contributes to the EDPB initiatives toward the harmonization of certain procedural provisions and overcoming the differences in the conduct of cross-border proceedings. Most of the research considerations are supported by a study of the case that received much public attention and involves the first administrative fine in Croatia. Arguments are provided toward prescribing time limits for the resolution of data protection administrative disputes and toward appropriate addressal of the closely related issues of publishing CPDPA rulings, with the concerns of their accessibility worked out through a comprehensive policy. This includes also the particular considerations on the corrective measures issued to public authorities, which cannot be fined, and on the underdeveloped fine-limitation rule for certain other public sector bodies. Public interest concerns should be closely examined in the assessment of communicating information on relevant data protection cases and CPDPA decisions, as well as the interrelation with the freedom of information requests. The publishing of non-anonymous final rulings should be recognized as a form of additional sanction and power of the data protection authority and as such further explored also at the EU level. In terms of more efficient CPDPA functioning it is argued that the prescribed time limits for issuing expert opinions are extended. At the same time resources should be utilized toward better inclusivity and accessibility of relevant information, primarily rulings, on its website.

A dynamic structural model of labor supply, welfare participation, and food stamp participation is estimated using the 1992, 1993, and 1996 panels of the Survey of Income and Program Participation. Details of various policies including welfare time limits, work requirements, and Earned Income Tax Credit (EITC) are incorporated formally in the budget constraint. Policy simulations reveal that the economy accounts for half of the increase in the labor supply of female heads of family between 1992 and 1999. A time limit results in a larger efficiency gain than a work requirement or a direct reduction in welfare benefits. A reform package can lead to both a reduction in the government expenditure and an improvement in utility. The EITC expansion results in a substantial efficiency gain among individuals with the lowest expected wage. These individuals are almost unaffected by the economic expansion, but their income and utility increase significantly under the reform package.

•A meta-analysis across 131 studies shows not all scarcity effects are equal.•Demand-based scarcity is most effective for utilitarian products.•Supply-based scarcity has large effects on the purchase intentions of experiences.•Time-based scarcity has the greatest effect on high involvement products.•Managers need to consider these factors to maximize the success of scarcity tactics. Scarcity tactics are an essential tool for marketers. Cues that signal the current or potential unavailability of a product generally enhance its value and desirability and in turn increase purchase intentions. While there have been earlier reviews, the fragmented nature of the research to date means there is no cohesion across findings. Given that retailers employ a variety of scarcity cues in a diversity of settings, it is important to identify the magnitude of the effect of scarcity cues and how the effect on consumers’ purchase intentions changes across conditions. This research presents a meta-analysis of 416 effect sizes from 131 studies. Results show that demand-based scarcity is most effective for utilitarian products, supply-based scarcity for experiences, and time-based scarcity for high involvement products. The results show that managers need to consider the above factors to maximize the success of scarcity tactics in their marketing campaigns. [Display omitted]

Nanostructures proved to be versatile platforms to control the electromagnetic field at subwavelength scale. Indeed, high-quality-factors nanocavities have been used to boost and control nonlinear frequency generation by increasing the light–matter interaction. However, nonlinear processes are triggered by high-intensities, which are provided by ultrashort laser pulses with large bandwidth, which cannot be fully exploited in such devices. Time-varying optical systems allow one to overcome the time-bandwidth limit by modulating the cavity external coupling. Here we present a general treatment, based on coupled mode theory, to describe second harmonic generation in a doubly resonant cavity for which the quality-factor at the fundamental frequency is modulated in time. We identify the initial quality factor maximizing second harmonic efficiency when performing -boosting and we predict a theoretical energy conversion efficiency close to unity. Our results have direct impact on the design of next generation time-dependent metasurfaces to boost nonlinear frequency conversion of ultrashort laser pulses.

We propose that externally induced time limits on a task overly affect predictions of other people’s completion times for that task, due to an over-generalized association between the time available and inferred task scope. We find higher estimates of the time needed to complete a given task by another person when the time limit is longer. While such predictions could be normative when time limits are informative, the effect persists even when the decision-maker knows that the limit is arbitrary and is unknown to the other person, and therefore, cannot affect behavior. Perception of task scope mediates the relationship between time limits and completion time estimates, and weakening the association between time limits and task scope attenuates the effect. The over-learned cognitive bias persists even among experienced decision-makers making estimates in a familiar setting. Our findings have implications for people who make decisions that use judgments of others’ task completion time as an input.

The 1994 Egyptian Arbitration Act has conferred the jurisdiction to terminate arbitral proceedings, if the time limit for the award expires, on Egypt's courts. The Egyptian courts have wrongfully terminated two International Chamber of Commerce arbitration proceedings. Egypt's Court of Cassation has ultimately reversed the decisions of the Egyptian lower courts, so the two icc arbitration awards have survived. This article examines the manner in which the Egyptian courts were asked to grant, recognise or refuse to recognise the termination orders, and clarifies how arbitrators, the icc Court and parties reacted to them.

There is little empirical understanding of how young children's screen engagement links to their well‐being. Data from 19,957 telephone interviews with parents of 2‐ to 5‐year‐olds assessed their children's digital screen use and psychological well‐being in terms of caregiver attachment, resilience, curiosity, and positive affect in the past month. Evidence did not support implementing limits (< 1 or < 2 hr/day) as recommended by the American Academy of Pediatrics, once variability in child ethnicity, age, gender, household income, and caregiver educational attainment were considered. Yet, small parabolic functions linked screen time to attachment and positive affect. Results suggest a critical cost–benefit analysis is needed to determine whether setting firm limits constitutes a judicious use of caregiver and professional resources.

Employee task performance is considered to be of crucial importance for organizational survival and growth, at the same time, the struggle for organizational survival and growth most especially in the current economic climate gives rise to perceptions of job insecurity among employees thereby making the perception of job insecurity a relevant topic. This study examined the effect of perceived job insecurity on task performance. In addition, the effect of both quantitative and qualitative facets of job insecurity on the different components of task performance, was investigated. By making use of the multi-stage sampling technique, a total of 342 employees with age range of 23 to 46 years were proportionately selected from the cluster that represents each bank. Furthermore, the close ended and structured questionnaire was utilized in a descriptive cross-sectional research design to elicit responses from these employees. Based on the regression analysis conducted, it was revealed that while perceived job insecurity as a uni-dimensional construct exercise a significant and negative effect on task performance, both quantitative and qualitative job insecurity also have a significant and negative effect on this performance with the later, found to exercise a stronger negative impact. Furthermore, results also indicate that while quantitative job insecurity is more negatively related with the job quality component of performance, both job quantity and job time limit are more negatively related with qualitative job insecurity. To conclude, recommendations were made on the need for organizations to focus intervention on antecedents of job insecurity which have been classified as macro level, micro level and personality factors with the view of reducing the incidence of perceived job insecurity. It was also recommended that managers should endeavor to concentrate more resources on those employees who suffer from qualitative job insecurity whenever there is a need to make use of these interventions, while also being in cognizant of the fact that a different level of intervention is required for employees with different level of job quality, job quantity and job time limit.

Experiments comparing intuitive and reflective decisions provide insights into the cognitive foundations of human behavior. However, the relative strengths and weaknesses of the frequently used experimental techniques for activating intuition and reflection remain unknown. In a large-scale preregistered online experiment ( N  = 3667), we compared the effects of eight reflection, six intuition, and two within-subjects manipulations on actual and self-reported measures of cognitive performance. Compared to the overall control, the long debiasing training was the most effective technique for increasing actual reflection scores, and the emotion induction was the most effective technique for increasing actual intuition scores. In contrast, the reason and the intuition recall, the reason induction, and the brief time delay conditions failed to achieve the intended effects. We recommend using the debiasing training, the decision justification, or the monetary incentives technique to activate reflection, and the emotion induction, the cognitive load, or the time pressure technique to activate intuition.

The unavoidable interaction of an open quantum system with its surrounding environment may follow non-Markovian dynamics behavior, which causes its memory effects to play a key role in many quantum technologies. In this work, we first consider the dynamics control of a spin-1/2 system that simultaneously interacts with two magnets. Subsequently, we study in detail the evolution of a classically driven spin-1/2 system that is coupled with a magnet. Two dynamical crossovers of the spin system, namely, from Markovian dynamics to non-Markovian dynamics and from no-speedup evolution to speedup evolution, can be controlled in these two models. Slightly different from the previous quantum speedup scenarios with controllable non-Markovianity, the stronger non-Markovianity does not necessarily lead to the quantum speedup dynamics process of the spin system in our spin-magnet schemes.
