Spatial variability of sedimentary assemblages reflects variations in bioerosion pressure of adjacent coral reefs.

The composition of coral-reef sediments is highly variable across space and time, and differences in the life histories of the dominant calcifying organisms on reefs contribute to the heterogeneity of reef sediments. Previous studies have suggested that variations in coral-reef bioerosion can influence spatial and temporal variations of sedimentary assemblages: elevated erosion rates of dead coral skeletons can trigger a pulse of coral-derived sediments and cause a shift in the dominance of sedimentary grains from coralline algae, such as Halimeda, to coral. We assessed the variability of the sedimentary composition and bioerosion rates of reefs at different spatial scales to determine the association between these two variables. We surveyed the benthic assemblages on reefs exhibiting different ecological states and collected samples of the associated sediments. We calculated the carbonate budget for each site and compared their variability at different hierarchical levels to the variability of their respective sedimentary assemblages. At the scale of sites (1-10 km), Halimeda cover was a significant predictor of the relative abundance of Halimeda grains. Both the relative abundance of coral grains and reef bioerosion rates varied significantly at the scale of locality (tens to hundreds of km), with high abundances of coral grains in the sediments coinciding with high rates of bioerosion. The main drivers of bioerosion at our localities were parrotfish assemblages dominated by large size classes of excavating species such as Sparisoma viride. Reef sediments may reflect the gross degree of bioerosion pressure that reefs experience, and historical changes in bioerosion rates could potentially be assessed by examining the sediments across temporal scales.

Historical Cohort Differences in Views on Aging in the US: A Trend Toward Longer Midlife but Older Felt Age.

This study compared equal age groups from two cohorts from the Midlife in the United States (MIDUS) study surveyed at different times to characterize societal changes in measures of subjective age and age threshold. Two successive MIDUS cohorts were utilized (1995-1996 and 2011-2014; age range 25-74). Outcomes included subjective age (felt age and desired age) and age threshold. Following multiple imputations of missing data and balancing methods, weighted linear regression measured associations between subjective age outcomes and cohort, sex, and chronological age. Individuals of the later MIDUS cohort reported older felt age and younger desired age in middle age groups (35-64 years old). An increase in age threshold was observed only in older age groups (65+). Possible underlying historical changes in health and societal age stereotypes are explored to explain the observed trend toward older felt age and age threshold, but a younger desired age.

Agricultural Productivity and Climate Mitigation

Agriculture will play a central role in meeting greenhouse gas (GHG) emission targets, as the sector currently contributes ∼22% of global emissions. Because emissions are directly tied to resources employed in farm production, such as land, fertilizer, and ruminant animals, the productivity of input use tends to be inversely related to emissions intensity. We review evidence on how productivity gains in agriculture have contributed to historical changes in emissions, how they affect land use emissions both locally and globally, and how investments in research and development (R&D) affect productivity and therefore emissions. The world average agricultural emissions intensity fell by more than half since 1990, with a strong correlation between a region's agricultural productivity growth and reduction in emissions intensity. Additional investment in agricultural R&D offers an opportunity for cost-effective (<US$30 per ton carbon dioxide) and large-scale emissions reductions. Innovations that target specific commodities or inputs could even further reduce the cost of climate mitigation in agriculture.

Spatial and historical patterns of sedimentary organic matter sources and environmental changes in the Ross Sea, Antarctic: implication from bulk and n-alkane proxies

Organic carbon (OC) burial in the Antarctic marginal seas is essential for regulating global climate, particularly due to its association with ice shelf retreat. Here, we analyzed total OC (TOC), total nitrogen (TN), radiocarbon isotope, n-alkanes and relative indicators in surface and core sediments from the Ross Sea, West Antarctica. Our aim was to investigate spatial and historical changes in OC sources, and to explore the influencing factors and implications for ice shelf retreat since the last glacial maximum (LGM). Our results revealed distinct spatial patterns of OC sources as indicated by n-alkane indicators in surface sediments. In the Western Ross Sea, n-alkanes predominantly originated from phytoplankton and bacteria, as evidenced by their unimodal distribution, low carbon preference index (CPI) of short-chain n-alkanes (CPIL = 1.41 ± 0.30), and low terrestrial/aquatic ratio (TAR = 0.22 ± 0.14). In the Southwest Ross Sea, n-alkanes were derived from marine algae and terrestrial bryophytes, indicated by bimodal distribution, low ratio of low/high molecular-weight n-alkanes (L/H = 0.62 ± 0.21), low CPI of long-chain n-alkanes (CPIH = 1.18 ± 0.16), and high TAR (1.26 ± 0.66). In contrast, the Eastern Ross Sea exhibited n-alkanes that were a combination of phytoplankton and dust from Antarctic soils and/or leaf waxes from mid-latitude higher plant, as suggested by both unimodal and bimodal distributions, high L/H (1.60 ± 0.58) and CPIH (2.04 ± 0.28), and medium TAR (0.61 ± 0.30). Geologically, during the LGM (27.3 – 21.0 ka before present (BP)), there was an increased supply of terrestrial OC (TOC/TN = 13.63 ± 1.29, bimodal distribution of n-alkanes with main carbon peaks at nC17/nC19 and nC27). From 21.0 to 8.2 ka BP, as glaciers retreated and temperatures rose, the proportion of marine n-alkanes significantly increased (TOC/TN = 9.09 ± 1.82, bimodal distribution of n-alkanes with main carbon peaks at nC18/nC19 and nC25). From 8.2 ka BP to the present, as the ice shelf continued to retreat to its current position, the marine contribution became dominant (TOC/TN = 8.18 ± 0.51, unimodal distribution of n-alkanes with main carbon peak at nC17/nC18/nC19, and low TAR (0.41 ± 0.32)). This research has significant implications for understanding the variations in Antarctic OC sources and their climatic impacts in the context of accelerated glacier melting.

Game-based Learning for History: Student Perceptions and Preferences

With the rapid development of games in the 21st century, the panoply of games on history shows a wide variety. Backstories from most historical eras have been implemented in different game genres and modalities. Furthermore, a growing number of studies have pointed to the didactic potential of historical games as learning tools. This study aims at investigating university students' perceptions of gaming and their game preferences, with a particular focus on history. The research question to answer was: "What types of games do history students play, and how can games, in their view, contribute to learning in their subject?" Educational action research was used as the overall strategy in a study where data was collected from five different university course groups in general history at the basic level. Students answered questionnaires with open ended questions about gaming preferences and their perceptions of games. The answers were then analysed in an inductive thematic analysis. Findings show that the students play a mix of analogue board games, digital games and hybrid forms. In the transmedial array of games available, important genres include role playing games, strategy games, quizzes and first-person action games. The students frequently provide arguments for the use of games in history education, and they give reasons why they find a particular game useful for this purpose. They describe how these games have a potential to add value to history education. To some extent, they also discuss how this can be implemented. In conclusion, the authors argue that so-called technology tree games are particularly relevant to learning history from a structural perspective, while RPG:s can strengthen interpretive approaches through a subjective historical experience.

”Un compositeur d’un grand mêrite” i Paris – Laura Netzel och hennes kammarmusik vid ingången till kvinnornas århundrade

An interest in women in Nordic music history and a fascination with Laura Netzel's (1839–1927) chamber music characterises this article. In addition to focusing on works, reception, and context, the article examines the question of what role did gender play in the reception of Netzel's and her women colleagues' chamber music? How is the reviewers' understandings of gender and originality intertwined into their texts in daily newspapers and music magazines? And finally: Do possibilities for a transformation towards a more equal chamber music repertoire and more equal music history books exist? Despite Anna Rogstad's (1854–1938) predictions that the 20th century would become "the women's century," the concert scene, and the chamber music environment in particular, was characterized by gender-related prejudices. Still, Laura Netzel received recognition for her great originality and captivating musicality when she stayed in Paris at the turn of the century. In contrast to her male Nordic colleagues, she received glowing reviews where the works are described as bold and permeated with a Nordic tone. The article focuses on two chamber music works from one of her stays in Paris: Cello Sonata, opus 66 and Piano Trio in D minor, opus 78. In the Sonata for Cello and Piano, we encounter a very expressive and mature, but also bold, forward rushing and adventurous Netzel. The style is late Romantic, but also clearly influenced by contemporary French music and in constant development. The harmonics are exploratory, but never proved too demanding for the audience and critics of the time. The Trio for Violin, Cello and Piano in D minor was premiered in 1903 at La société Musique Nouvelle with Netzel herself at the piano. Enthusiastic Scandinavians in the audience were seated together with several famous music authorities of the French capital. Le Monde musical praised it for being written with such great confidence.

Obiajulu’s Children and the Wicked Sons of Eli (1 Sam 2:11–17)

The two sons of Eli, Hophni and Phinehas (1 Sam 2:11-36), served along with their father as priests at Shiloh in the tabernacle, where the ark of the covenant was housed (11am 1:3). While in service, Eli’s children became sons of worthlessness (bənȇ-bəliyyaʿal), dishonest, wicked and corrupt, as well as refused to know the Lord (lō’ yāḏə‘û ՚eṯ-ʾădōnāi) and his teachings. They were unrighteous, greedy, intimidating, immoral, and abusive to women at the entrance of the temple (vv. 12-22). Eli did little to correct them, leading to God’s punishment. Some scholars have examined this narrative with Western historical models, lacking African stories, cultures, customs, and experiences, where there are similar incidences of children’s misbehaviors and challenges of their upbringing in the African context. Using an African Biblical Hermeneutical approach with illustrative stories from Zain E. Asher’s memoir, “Where the Children Take Us: How One Family Achieved the Unimaginable,” this work contextually examines 1 Sam 2:11-17, within the theological contexts of the Books of Samuel and Deuteronomistic History (Josh–2 Kings). It compares Obiajulu’s disciplined and trained children (Obinze, Chiwetel, Zain, Kandibe) and the obedient boy, Samuel (vv. 18-22), with the consequences of the blasphemies and corruption of Eli’s children (vv. 11-17). It proposes lessons that no matter how we perform our duties in the church, schools and families, sadness may still come if we neglect to train our children responsibly in righteousness, integrity, hard work, and in the fear of the Lord.

Prevalence of anemia and related factors among Tabari cohort population: a cross-sectional study

BackgroundAnemia presents a considerable public health challenge, standing as a leading contributor to elevated rates of mortality and morbidity. Therefore, this study aimed to investigate the prevalence of anemia and related factors among Tabari cohort population.MethodsThis study involved a cross-sectional investigation carried out during the enrollment phase of the Tabari cohort. The Tabari cohort is a subset of the larger nationwide cohort study known as the “Prospective Epidemiological Research Studies in IrAN” (PERSIAN) cohort. The collected data included general information, anthropometric measurements, medical history and blood samples. Anemia was defined as a hemoglobin level less than 13 mg/dL for men and less than 12 mg/dL for women. Data were analyzed using SPSS V.16.ResultsOut of the 10,073 participants included in the analysis, 1,352 individuals (13.4%) were diagnosed with anemia. In the multiple regression analysis, the odds of anemia were significantly 2.31 times in females compared to males, 3.69 times in urban residents compared to rural residents, 1.41 times in social economic categories of IV and 1.35 in social economic categories of V compared to social economic categories of I, 1.70 times in drug abuse compared to non-drug abuse, 0.71 times in body mass index (BMI) categories of 25–29.9 kg/m² and 0.70 in BMI ≥ 30 kg/m² compared to BMI < 25, 0.77 times for triglycerides(TG) > 150 compared to below 150, 0.76 times for total cholesterol(TC) > 200 compared to below 200, 0.83 times for high waist-to-hip ratio (WHR) compared to low WHR, 1.33 times in low High-density Lipoprotein (HDL) compared to high HDL, 1.18 times in diabetics (DM) compared to non-DM, and 1.37 times in individuals with coronary heart diseases (CHD) compared to healthy individuals.ConclusionAnemia was a prevalent condition among Tabari cohort population. Several conditions including female gender, urban residence, Social economic level of IV and V, drug abuse, low HDL, high WHR, DM, and CHD conditions were significantly associated with increased odds of anemia. Furthermore, BMI categories of 25–29.9 kg/m² and ≥ 30 kg/m², high TC and high TG were significantly associated with decreased odds of anemia among this population.

Historical change in associations between perceived risk, disapproval, and use of cannabis among young adults ages 19–30, 2011–2022

BackgroundThe current study used U.S. young adult data to examine overall and age group-specific historical trends in (a) mean perceived risk and disapproval of cannabis use, and (b) risk/use and disapproval/use associations. MethodsData were collected from 2011 to 2022 from 16,492 respondents aged 19–30 in the national Monitoring the Future panel study. Trends in mean risk and disapproval overall and by age group (19–22, 23–26, 27–30) were modeled. Models regressing any past 30-day cannabis use on risk and disapproval controlled for sex, race/ethnicity, college education, population density, state cannabis policy, region, and year. Age group differences and historical trends in regression estimates from year-specific models were examined. ResultsFrom 2011 to 2022, overall mean perceived risk decreased from 3.08 (just over moderate) to 2.50 (between slight and moderate); mean disapproval decreased from 2.21 (between disapprove and strongly disapprove) to 1.66 (between don’t disapprove and disapprove). Higher risk and disapproval were independently associated with lower odds of past 30-day cannabis use overall (AORs 0.86 and 0.76, respectively); controlling for sociodemographics and state policy had virtually no impact on association strength. There were no significant age-related association differences. The risk/use association weakened from AOR 0.84 in 2011 to AOR 0.91 in 2022; the disapproval/use association remained stable (AORs 0.753 and 0.749). ConclusionsYoung adults now perceive cannabis as less risky and are less disapproving of using than they were a decade ago. Perceived risk has weakened as a cannabis use risk factor over time; disapproval has remained a stable risk factor.

Sedimentary antimony stable isotope record of anthropogenic contamination in a karst lake in southwestern China

Anthropogenic sources of antimony (Sb) are an important driver of pollution in the Earth environment, but their roles in the historical changes of Sb pollution in lake ecosystems are currently poorly understood. This study documents the sedimentary Sb deposition fluxes in Hongfeng lake (HFL), in southwestern China during 1958–2021 and quantifies the changes of anthropogenic contributions to sediments using Sb stable isotopes. Mean Sb concentration (mean: 1.89 mg kg−1) and deposition flux (mean: 302.1 ng cm−2 a−1) in lake sediments remained relatively stable from 1958 to 1980. Sb deposition fluxes increased rapidly since 1980, peaked at 990.8 ng cm−2 a−1 in 2000, and then decreased consistently, reaching 306.9 ng cm−2 a−1 in 2021. Generally, the historical changes in Sb isotopes were anticorrelated with Sb deposition fluxes and enrichment factors, suggesting a lower ε123Sb signature in anthropogenic loading sources, and highlight the ability of Sb isotopes to distinguish anthropogenic signatures from natural processes in complex hydrological systems. Using a binary end-member mixing model, the contributions of anthropogenic sources to the accumulated of Sb in the lake sediments were estimated to be 20 % before 1980s and increased approximate 58 % during 2000–2015, then decreased to 24 % in 2021, likely reflecting the changes of degree in regional industrial activities. Our results help to better understand the response of Sb pollutions to anthropogenic activities and would in turn benefit the controls Sb contamination in lake ecosystems.

Morfológiai vizsgálatok Magyarország délnyugati határfolyóin = Morphological Studies on South-Western Border Rivers in Hungary

Nowadays, the preservation and sustainable use of our natural values are increasingly coming to the fore, and this has implications not only for economic and field development but also for ecological aspects. In recent years, attention has shifted towards river morphological studies, which were previously relegated to the background. Understanding long-term changes and assessing the current state is essential to estimate future processes. In this article, we present our morphological studies on the Hungarian–Croatian border sections of the Mura and the Drava rivers. Historical changes were analyzed through a comparative study of historical maps from earlier periods, while the evaluation of the current state was conducted based on a detailed terrain model from a recent survey. GIS evaluation was also compared with sediment transport and flow measurement results. This comparison suggests that the morphological status of the river section under study is consistent with the typical parameters of transport processes.

The genetic consequences of historic climate change on the contemporary population structure of a widespread temperate North American songbird

Studies of widely distributed species can inform our understanding of how past demographic events tied to historic glaciation and ongoing population genetic processes interact to shape contemporaneous patterns of biodiversity at a continental scale. In this study, we used whole-genome resequencing to investigate the current population structure and genetic signatures of past demographic events in the widespread migratory American goldfinch (Spinus tristis). Phylogenetic relationships inferred from whole mitochondrial genomes were poorly resolved. In contrast, a genome-wide panel of > 4.5 million single nucleotide polymorphisms (SNPs) strongly supported the existence of eastern and western populations separated by western mountain ranges and additional population structuring within the western clade. Demographic modeling estimated that the eastern and western populations diverged approximately one million years ago, and both populations experienced subsequent population bottlenecks during the last glacial period. Species distribution models showed a severe contraction of suitable habitat for the American goldfinch during this period, with predicted discontinuities that are consistent with multiple, isolated glacial refugia that coincide with present-day population structure. Low overall genetic differentiation between the eastern and western populations (FST ∼ 0.01) suggests ongoing gene flow accompanied divergence, and individuals with admixed genomic signatures were sampled along a potential contact zone. Nevertheless, outlier SNPs were identified near genes associated with feather color, song, and migratory behavior and provide strong candidates for further study of the mechanisms underlying reproductive isolation and speciation in birds.

Reconstructing the past environmental conditions of southwestern India using estuarine sediment core

Geological archives can be examined via multiple proxies to uncover significant information about historical environmental changes. In comparison to single proxy approach, the use of multiple proxies can provide better resolution of the paleoenvironmental record. Thus, in the present study, to understand the paleoenvironmental conditions in the Kali coast in southwestern India, sedimentological, geochemical and isotopic (210Pb, 137Cs) proxies were used. The findings demonstrated that, in previous decades, the sedimentation rate varied from 0.5 to 1.0 cm/year under conditions with relatively higher hydrodynamic energy that were more common and fluctuating, allowing for larger sand particle deposition. However, in more recent years, finer particle deposition towards the surface has been observed under conditions with lower and more stable hydrodynamic energy, with a sedimentation rate of 1.87 cm/year. Additionally, the finer fractions displayed a strong correlation with the metal distribution, which was mostly governed by Fe-Mn oxides. Furthermore, it can be revealed that the environment was warm, humid, and marine-like between 1995 and 2000 based on chemical weathering intensity values and Rb/K ratios. A subtle shift to a freshwater habitat with relatively less warm, less humid climate occurred between 2000 and 2020. Therefore, similar research with longer depositional histories coupled with multiple proxies can help predict the future climatic shifts in decadal time scales.

Practitioners’ Experiences of School Readiness in Rural Early Childhood Centres in QwaQwa Free State, South Africa

The analysis of the school preparation experiences of rural early childhood practitioners. Multiple complex issues exist regarding school preparedness in South Africa. Research has found that many South African children are unprepared for formal schooling. Some of the challenges experienced by these young learners were low reading strength, learning setbacks and complications, and sluggish general development. As a result of these issues, young children face long-term repercussions. These include the inability to escape the cycle of poverty, lack of educational support, and poor socioeconomic conditions within their environment. Therefore, it can be argued that teaching within the South African public schooling context is marred with difficulties and unforeseen challenges. It is difficult to imagine how to modify South African infrastructure so all children can reach their full potential. Given that our ancient past is still rife with historical and power changes, the government must consider several factors while developing ways to aid transformation. This study investigated the perspectives of practitioners on school preparedness. At the same time, it investigates the significant learning at the grass-roots level that emerged from participation in a critical paradigm-based participatory action research project. The study is anchored in a philosophical methodology that leverages Practitioners’ idea that early childhood learners are ready for formal school. They do not emphasize play as a pedagogy for learning in preparation for school readiness. This paper is grounded in constructivism, which helps comprehend how school readiness knowledge improves formal education for young students. The author used the qualitative research approach with an interpretive paradigm to explore practitioners’ school readiness experiences. The author developed a semi-structured interview schedule to collect data from six practitioners in the Thabo-Mofutsanyana district in the Free State Province. The findings revealed practitioners lacked appropriate training and support in preparing young learners in ECD centres. Furthermore, practitioners lacked appropriate pedagogical skills to strengthen teaching and learning. The study recommended that practitioners receive ongoing professional teacher development in school readiness and use various teaching and learning strategies such as play pedagogy.

Paleoenvironmental characterization and historical trends of polycyclic aromatic hydrocarbons (PAHs) of Nutrias Lagoon, Uruguay

Concentrations of polycyclic aromatic hydrocarbons were assessed in a sediment core retrieved from Nutrias Lagoon, located within the Rocha Lagoon Protected Area along the SE Uruguayan coast. Using a 210Pb chronology, we reconstructed the historical accumulation of polycyclic aromatic hydrocarbons over the past 123 years (1895-2018). This study, the first of its kind in Uruguay, fills a research gap in understanding historical PAH accumulation and source changes. Our examination of dating, geochemical, and sedimentological data unveiled four main events, with minor instances in 1956±5 and 1964±4, and more significant occurrences in 1914±9 and 1997±2. Additionally, two prominent trend shifts were identified, one predating 1900 and the other in 1986±2. Before 1900, a dry spell was apparent, supported by all proxies, alongside a notable surge in heavy polycyclic aromatic hydrocarbons, likely attributed to fires during this arid period. Post-1986±2, a rise in sedimentation rates in the lagoon was observed, possibly due to increased rainfall. Also, the eutrophication of the lagoon over the years can be observed. Furthermore, a recent increase in polycyclic aromatic hydrocarbons influx at the core's surface was linked to the construction of a nearby lagoon bridge and associated roadwork. Our findings suggest that atmospheric deposition constitutes the primary source of polycyclic aromatic hydrocarbons in the lagoon, offering insights into its recent environmental history and basin dynamics. This study establishes a critical baseline for future research in the region and facilitates the development of effective and sustainable environmental management strategies.

Similar disease progression in nonsense Duchenne Muscular Dystrophy boys as general natural history: single Brazilian center 15 years registry view.

Duchenne muscular dystrophy is a progressive and fatal X-linked neuromuscular disease. Emergent disease-modifying therapy (DMT) in nonsense Duchenne muscular dystrophy (nmDMD) has brought new perspectives to slow down functional decline in this fatal disease. To investigate if there are differences in natural history between nmDMD and other genotypes, we described a retrospective cohort analysis of 25 nonsense mutation DMD (nmDMD) boys without disease-modifying therapy, aged between 1 and 22 years, over the last 15 years (2007-2022) in a single neuromuscular center in Rio de Janeiro and use published data on DMD natural history for comparison. Regarding prognostic factors, there were remarkable and statistically significant early loss of ambulation (at 9.1y ±2.1) and shortening of life expectancy (17.6y ±2.1) in our nmDMD group. Late acquisition of neurodevelopmental milestones and annual rates of decline in respiratory, cardiac, and timed motor function tests are the same between nmDMD patients with standard care and other DMD genotypes as described in the literature. Our data indicates the similarity of natural history and disease progression among DMD boys with nmDMD mutations compared to different mutations.

Influence of Osteoporosis on the Course of Apical Periodontitis.

Osteoporosis is a disease characterized by disruption of the bone microarchitecture. It is observed in both sexes, but to a greater extent in women. It affects the whole body, including the jaws. The main indicator of the presence of osteoporosis accepted by the World Health Organization is bone mineral density. The aim of this article is to find data on the influence of osteoporosis on apical periodontitis, to investigate how the intake of osteoporosis drugs affects apical periodontitis, and to establish various data that may be of benefit to the dental practitioner when treating patients with osteoporosis and apical periodontitis. Open-access publications are included. The presence of osteoporosis is important to the dentist. Apical periodontitis in these patients has a faster progression. They are characterized by inflammation and destruction of the tissues located around the tooth root. Osteoporosis has a destructive effect on bone tissue through different mechanisms: nuclear factor-κβ ligand and NLRP3/Caspase-1/IL-1β cascade. It is also associated with low estrogen levels. Various medications such as corticosteroids, bisphosphonates (alendronate, zoledronate (Zoledronic acid), calcitonin, raloxifene, and strontium used to treat osteoporosis can affect the course of apical periodontitis. When treating patients with periapical lesions, the dentist must take a proper medical history and general medical history. In cases of osteoporosis or taking bisphosphonates and other medications, consideration should be given to whether consultation with a specialist is necessary, what treatment approach would be most appropriate, and what the prognosis will be. Chronic diseases affect both the general state of the body and dental health. It has been found that in patients with osteoporosis, inflammation of the apical periodontium develops with faster bone resorption. Before starting dental treatment, it is important to specify the etiology of osteoporosis, the bone density of each patient, as well as the medications they are taking.

Business Cycle Dynamics in the Romanian Economy: Phases and Developments

Romania's economy is not yet sufficient / complete and competitive connected to the developed European economy and the global one. In recent economic and general political history, the political, institutional and economic changes that have taken place since 1990 in Central and Eastern Europe, including Romania, are already recognized. The article deals with the evolutionary situational stages towards the New Economy of Romania. It also describes the post-transformation horizon for achieving quasi-constant inverted levels between “tangible-intangible” for the transition to a new business cycle in the New Knowledge-Based Economy and Risk. It follows that if GDP reflects the sum of the market value of all goods and services intended for final consumption, not intermediate ones, produced in all branches of the economy within Romania within a year, by way of investigative proximity, business and cycles of manifestation of these were closely followed by dimensional evolutionary trends of similarity and aggregation with GDP. In fact, the New Knowledge-Based Economy has radically and positively changed Romania's advance towards the digitalized society, based more and more on the operationalization of intangible assets. The problem of vision, strategy and development tactics through new business cycles is found in the search for the optimal structural ratio between tangible and intangible assets (knowledge) insurers for competitiveness and sustainability.
