The European 2030 climate and energy package: do domestic strategy adaptations precede EU policy change?

The European Union’s 2030 climate and energy package introduced fundamental changes compared to its 2020 predecessor. These changes included a stronger focus on the internal market and an increased emphasis on technology-neutral decarbonization while simultaneously de-emphasizing the renewables target. This article investigates whether changes in domestic policy strategies of leading member states in European climate policy preceded the observed changes in EU policy. Disaggregating strategic change into changes in different elements (goals, objectives, instrumental logic), allows us to go beyond analyzing the relative prioritization of different goals, and to analyze how policy requirements for reaching those goals were dynamically redefined over time. To this end, we introduce a new method, which based on insights from social network analysis, enables us to systematically trace those strategic chances. We find that shifts in national strategies of the investigated member states preceded the shift in EU policy. In particular, countries reframed their understanding of supply security, and pushed for the internal electricity market also as a security measure to balance fluctuating renewables. Hence, the increasing focus on markets and market integration in the European 2030 package echoed the increasingly central role of the internal market for electricity supply security in national strategies. These findings also highlight that countries dynamically redefined their goals relative to the different phases of the energy transition.

     

Determination of Herbicides Paraquat,Glyphosate, and Aminomethylphosphonic Acid in Marijuana Samples by Capillary Electrophoresis

In this work, two methods were developed to determine herbicides paraquat, glyphosate, and aminomethylphosphonic acid (AMPA) in marijuana samples by capillary electrophoresis. For paraquat analysis, sample was extracted with aqueous acetic acid solution and analyzed by capillary zone electrophoresis with direct UV detection. The running electrolyte was 50 mmol/L phosphate buffer (pH 2.50). For glyphosate and AMPA, indirect UV/VIS detection was used, as these substances do not present chromophoric groups. Samples were extracted with 5 mmol/L hydrochloric acid. The running electrolyte was 10 mmol/L gallic acid, 6 mmol/L TRIS, and 0.1 mmol/L CTAB (pH = 4.7). The methods presented good linearity, precision, accuracy, and recovery. Paraquat was detected in 12 samples (n = 130), ranging from 0.01 to 25.1 mg/g. Three samples were positive for glyphosate (0.15–0.75 mg/g), and one sample presented AMPA as well. Experimental studies are suggested to evaluate the risks of these concentrations to marijuana user.     

Brazilian Regional Leadership Revisited: Testing the Long-Term Determinants of South American Followership (1995–2015)

Over the last twenty years, Brazil has staked successive claims to regional leadership, with varying explicitness and unclear success. What factors explain the acceptance or rejection of such claims by South American countries? This article summarises the literature on regional powers and frames regional powerhood as arising from geographical belonging, resources, and will to lead; and leadership/followership as stemming from exclusivity, hierarchy/influence, consensus, and provision. By analysing panel data on Brazil and South America from 1995 to 2015, the study concludes that Brasilia enjoyed higher followership in situations characterised by high exclusivity and consensus, and low hierarchy and provision. These conditions were present in South America in the 1990s, thus rendering that decade more receptive to Brazilian leadership.     

Age estimation through histological study of trabecular volume and cortical bone width of the iliac crest

There have been many methods proposed to estimate the age of human bones in forensic medicine or in forensic anthropology, including those that assess histological structures. In this study, age was evaluated through the histomorphometric study of trabecular volume and cortical width of the right iliac crest. A total of 25 samples A total of 66 samples (42 male and 24 female) were obtained from necropsies of judicial cases, with ages ranging from 13 to 58years, who had died a sudden or violent death. The samples were obtained using Bordier's trocar for bone biopsy, in a period not exceeding 24h after death. The samples were examined without decalcification, with 96° alcohol dehydration, embedding in methyl methacrylate, and sectioned with a microtome Reichert (3μm). The sections were fixed on microscope slides and stained using toluidine blue, Goldner trichrome and hematoxylin-eosin methods. The samples were studied under a Leica DM LB microscope and the images were digitally captured. The digital images were processed using an image analysis program and data were analyzed using the SPSS statistical package. The results demonstrated that the combination of the trabecular volume and cortical width acted as predictors of the age in subjects which did not suffer from any deterioration of bone and/or mineral metabolism.     

Searching the Soil: Forensic Importance of Edaphic Fauna After the Removal of a Corpse

Abstract: Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese–Tullgren funnels. Necrophagous fauna on the human remains was dominated by the fly Piophilidae: Stearibia nigriceps (Meigen, 1826), mites Ascidae: Proctolaelaps epuraeae (Hirschmann, 1963), Laelapidae: Hypoaspis (Gaeolaelaps) aculeifer (Canestrini, 1884), and the beetle Cleridae: Necrobia rufipes (de Geer, 1775). We confirm the importance of edaphic fauna, especially if the deceased is discovered in natural environs. Related fauna may remain for days after corpse removal and reveal information related to the circumstances of death. The species Nitidulidae: Omosita depressa (Linnaeus, 1758), Acaridae: Sancassania berlesei (Michael, 1903), Ascidae: Zerconopsis remiger (Kramer, 1876) and P. epuraeae, Urodinychidae: Uroobovella pulchella (Berlese, 1904), and Macrochelidae: Glyptholaspis americana (Berlese, 1888) were recorded for the first time in the Iberian Peninsula.     

Anxiety disorders and intimate partner violence: can the association be explained by coexisting conditions or borderline personality traits?

Intimate partner violence (IPV) is a serious, preventable public health problem. IPV perpetration is strongly associated with Anxiety disorders at the population level. We investigated whether the association could be explained by coexisting psychiatric conditions or Borderline personality traits, using a combined data-set of two National Household Surveys (n = 15,973). Results showed women were more likely to report perpetrating IPV than men. Anxiety disorders were associated with IPV. When coexisting psychiatric conditions together with a categorical diagnosis of Borderline Personality Disorder (BPD) were investigated as explanatory variables, 19.2% of the association between Anxiety disorders and IPV was explained. Using individual Borderline traits in place of a categorical diagnosis of BPD, 58.3% of the association was explained. In conclusion, the association between Anxiety disorders and IPV was partly, but not fully, explained by coexisting psychiatric conditions and individual Borderline traits. Perpetrators of IPV should be screened for Anxiety disorders and among those with Anxiety disorders, Borderline traits are important.     

Suicidal Smothering by Rubber Latex Gloves and Handkerchief

Asphyxial deaths are common in forensic practice, being sustained by a variety of mechanisms that cause an oxygen deficiency to the brain. Several classification models have been proposed in the literature, the most recent one being that of the International Network for Forensic Research Group (INFOR). This report describes an unusual case of suffocation where the obstruction of the airways was caused by a gag formed of three latex gloves and a handkerchief. The manner of death (differential diagnosis between homicide and suicide) and the different alternatives of classification are discussed.
