This study presents a novel framework that examines the integration of Policies, Institutions, and Regulations (PIR), uncovers existing gaps, provides insights into policy implementation, to enhance wastewater reuse practices. The research aims answer two key questions: 1) What are barriers PIR alignment hinder advancements reuse; 2) which reforms can be prioritized according their "implementability"? Using Portugal as case study, this demonstrates framework's applicability in identifying...
Remarkable progress has occurred over the years in performance evaluation of bank branches. Even though financial measures are usually considered most important assessing branch viability, we posit that insufficient attention been given to other factors affect branches’ potential profitability and attractiveness, such as: location features, trade area characteristics facilities management. Based on integrated use cognitive maps multiple criteria decision analysis, propose a framework adds...
Standard tests based on predictive regressions estimated over the full available sample data have tended to find little evidence of predictability in stock returns. Recent approaches analysis subsamples suggest fact that where it occurs might exist only within so-called "pockets predictability" rather than across entire sample. However, these methods are prone criticism subsample dates endogenously determined such use standard critical values appropriate for will result incorrectly sized...
The sources of economic growth are a recurrent theme in literature. However, the full range factors behind remains elusive. We still somewhat ignorant about forces that drive growth. A large part unexplained through typical analysis based on productive labor and capital. original idea this research is it moves away from traditional examines countries business perspective. If, company, we tend to look at various sectors, why not determinants country's same way? Therefore, embrace our...
As a consequence of the international financial crisis in 2007, region Algarve, where tourism plays an important economic and social role, suffered decrease demand, while unemployment increased sharply. Although activities registered quick recovery, levels continued to grow. This article examines impacts on sectorial structure regional economy, using Bayesian vector autoregressive model. The results reveal that growth did not automatically create expected positive performance other sectors,...
Introduction HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with MSM population newly diagnosed Portugal between 2014 and 2019. Methods included 391 HIV-1 Men who have Sex (MSM), from BESTHOPE project, 17 countrywide Portuguese hospitals. The data clinical socio-behavioral questionnaires viral genomic sequence obtained drug resistance test before starting antiretrovirals (ARVs). subtypes epidemiological surveillance mutations were...
The authors use the non-parametric method proposed by Harding and Pagan (2003) to date tourism growth cycles. This study is among first robust, transparent replicable dating rules in context of economic activity On basis a cycle indicator function, are able establish greater degree synchronization demand than that observed at level, and, means recursive correlation coefficient, they conclude this has increased over years. To analyse presence time lag between turning points cycles demand,...
Nevirapine is widely used for the treatment of HIV-1 infection; however, its chronic use has been associated with severe liver and skin toxicity. Women are at increased risk these toxic events, but reasons sex-related differences unclear. Disparities in biotransformation nevirapine generation metabolites between men women might be underlying cause. The present work aimed to explore sex as a potential factor nevirapine-induced All included subjects were adults who had receiving 400 mg once...
We propose a family of least-squares–based testing procedures that look to detect general forms fractional integration at the long-run and/or cyclical component time series, and are asymptotically equivalent Lagrange multiplier tests. Our setting extends Robinson’s (1994) results allow for short memory in regression framework generalizes Agiakloglou Newbold (1994), Tanaka (1999), Breitung Hassler (2002) by allowing single or multiple unit roots any frequency [0, π ]. procedure can be easily...
This paper presents an open-source watertight multirotor Unmanned Aerial Vehicle (UAV) capable of vertical takeoff and landing on both solid terrain water for environmental monitoring. The UAV's propulsion system has been designed so as to also enable the active control drift along surface. low power locomotion method, novel such a vehicle, aims extend available operation time bodies' surveys. ability take-off from allows UAV overcome any obstruction that appears its path, dam. A set field...
Integrase strand transfer inhibitor-based regimens are recommended for first-line therapy in human immunodeficiency virus type 2 (HIV-2). Nonetheless, dolutegravir (DTG) clinical trial data lacking.We conducted a phase 2, single-arm, open-label to evaluate the safety and efficacy of triple regimen that included DTG persons with HIV-2 (PWHIV-2) Portugal. Treatment-naive adults receive combination nucleoside reverse transcriptase inhibitors (NRTIs). Treatment was evaluated by proportion...
Abstract In this paper, we analyse the impact of persistent cycles on well‐known semi‐parametric unit root tests Phillips and Perron (1988, Biometrika , Vol. 75, pp. 335–346). It is shown, both analytically through Monte Carlo simulations, that presence complex (near) roots can severely bias size properties these tests. Given popularity with applied researchers their routine in most econometric software packages, results presented paper suggest practitioners should treat outcomes some...
Many electricity markets are experiencing profound changes due to the large-scale deployment of renewable energy. This paper analyzes effect wind and hydro power on wholesale prices. We focus Spanish market high penetration hydro, also availability data water stored in dams. estimate impact generation price level volatility through an ARX-GARCHX model. The results show that these two different renewables have impacts prices: intermittent increases volatility, while dispatchable reduces it....
This paper presents a robotic team suited for bottom sediment sampling and retrieval in mudflats, targeting environmental monitoring tasks. The encompasses four-wheel-steering ground vehicle, equipped with drilling tool designed to be able retain wet soil, multi-rotor aerial vehicle dynamic imagery acquisition. On-demand imagery, properly fused on an mosaic, is used by remote human operators specifying the mission supervising its execution. crucial success of study, as often it depends...
We extend the ${\cal M}$ class of unit root tests introduced by Stock (1999, Cointegration, Causality and Forecasting. A Festschrift in Honour Clive W.J. Granger . Oxford University Press), Perron Ng (1996, Review Economic Studies 63, 435–463) (2001, Econometrica 69, 1519–1554) to seasonal case, thereby developing semi-parametric alternatives regression-based augmented Hylleberg, Engle, Granger, Yoo (1990, Journal Econometrics 44, 215–238). The success this deliver good finite sample size...
Terrains of different nature exhibit distinct structural dynamics when exposed to wind due their own intrinsic material composition. This translates into peculiar optical flow patterns that can be used identify the terrain type. In this sense, paper proposes an active vision-based water detection model exploits predictable induced by downwash effect vertical take-off and landing Unmanned Aerial Vehicles (UAV). To determine whether a surface is below UAV, system tracks in video feed captured...
To describe and analyze transmitted drug resistance (TDR) between 2014 2019 in newly infected patients with HIV-1 Portugal to characterize its transmission networks.Clinical, socioepidemiological, risk behavior data were collected from 820 diagnosed September December 2019. The sequences obtained testing used for subtyping, TDR determination, cluster (TC) analyses.In Portugal, the overall prevalence of was 11.0%. presented a decreasing trend 16.7% 9.2% 2016 (p for-trend = 0.114)....
