Building a master sampling frame by linking the population and housing census with the agricultural census
Authors: Keita Naman , Gennari Pietro
Published: January 2025

The objective of the Global Strategy to Improve Agricultural and Rural Statistics is to enable developing countries to build a sound and comprehensive agricultural statistical system, that is sustainable, well integrated in the overall national statistical system and that is capable of responding to the information needs of the 21 ^{st} century. One of the three pillars of the Global Strategy is the integration of agriculture into the national statistical system which is obtained through three methodological tools: (i) an integrated survey framework, that defines the mix and frequency of data collection initiatives needed to meet the predefined data requirements; (ii) an integrated statistical data base, that provides data management system for different data sources (censuses, surveys, administrative data), using common definitions and classifications and ensuring that only one number is agreed as official statistics; (iii) a master sampling frame, that is the basis for selecting the sample of all agriculture-related surveys across the national statistical system, thus allowing coordinated data collections.

Little guidance is currently available on buiding a Master Sample Frame for agricultural surveys in different country contexts. The FAO and UNFPA Guidelines for Linking Population and Housing Censuses with Agricultura Censuses aim to fill this gap. This paper draws on the Guidelines and country reports to examine how the agricultural data collected through the Population Census can contribute to building a Master Sample Frame for agriculture censuses and surveys, with illustrations from the recent experience of Mozambique.
Agricultural Census 2010 in Hungary
Authors: Lengyel György
Published: January 2025

The agricultural censuses (AC) and farm structure surveys are the main data sources for designing, implementing and monitoring Common Agricultural Policy in the European Union. They have an important role in the system of agricultural statistics. They give an overall picture of the structure of agriculture in a given country, allowing its wide range analysis and provide one of the most used means for setting up the sampling frames for agricultural statistical surveys. Agricultural censuses have a long history in Hungary. The latest one was held in 2010. This presentation describes the legal background, the main differences compared to earlier censuses and some special topics as well. The use of administrative data sources is presented both during the preparation and processing phase together with the problems and solutions related to their use. The steps taken in order to assure data quality are also shown. The presentation contains information on data processing with special emphasis on the work done to be able to disseminate preliminary data 6 month after the reference day. The conversion of information on the location of the holding into geo-coordinates is presented in more detail.
Measuring indigenous populations across nations: Challenges for methodological alignment
Authors: Petry Bradley , Potts Erica
Published: January 2025

The social and political importance of the world's Indigenous peoples is highlighted by the United Nations and by a range of National Statistical Organisations and government agencies internationally who aim to identify and address some of the distinct social and economic characteristics observed in Indigenous populations. This paper outlines the historical and social context around enumeration and measurement of Indigenous peoples in Australia and offers an outline of current operational approaches across administrative and survey data. It also gives a comparative account of approaches taken by the United States of America, Canada and New Zealand, discussing historical contexts, their notions of Indigeneity and the collection methodology employed. Considerations are then offered toward the development of an internationally consistent approach to the measurement of Indigenous peoples. While Indigenous data is collected and compared across nations, collection methodologies differ, making comparisons less reliable and giving rise to the consideration for a standard international recording methodology. This preliminary review of current approaches and the documentation of known collection issues are of value in encouraging a wider strategic discussion around approaches to Indigenous statistics amongst nations.
SynLBD 2.0: Improving the synthetic Longitudinal Business Database
Authors: Kinney Satkartar K. , Reiter Jerome P. , Miranda Javier
Published: January 2025

In most countries, national statistical agencies do not release establishment-level business microdata, because doing so represents too large a risk to establishments' confidentiality. Agencies potentially can manage these risks by releasing synthetic microdata, i.e., individual establishment records simulated from statistical models designed to mimic the joint distribution of the underlying observed data. Previously, we used this approach to generate a public-use version – now available for public use – of the U.S. Census Bureau's Longitudinal Business Database (LBD), a longitudinal census of establishments dating back to 1976. While the synthetic LBD has proven to be a useful product, we now seek to improve and expand it by using new synthesis models and adding features. This article describes our efforts to create the second generation of the SynLBD, including synthesis procedures that we believe could be replicated in other contexts.
The evolving role of self-report surveys of criminal victimization in a system of statistics on crime and the administration of justice
Authors: Lynch James
Published: January 2025

Routinely collected statistics on crime and the administration of justice are essential for developing laws and policies that are responsive to the crime problem and for holding criminal justice agencies accountable in the execution of those policies. Any statistical system on crime and the administration of justice should include the opportunity for the direct participation of citizens in providing information on the crime problem. This direct participation enhances our ability to check on administrative record data and bolsters the legitimacy of these statistics more generally. Victimization surveys allow citizens to have this direct participation. The specific role of victimization surveys in a statistical system will depend upon the credibility and technical proficiencies of the police, court and correctional agencies. This paper describes the preferred role of victimization surveys and the technological challenges in playing that role under different conditions of legitimacy and technical capabilities.
Methodology and technology directions at Statistics New Zealand
Authors: Seyb Allyson J.
Published: January 2025

Statistics NZ aims to produce statistics that are fit for purpose in an efficient, sustainable and adaptive manner. However, balancing sound methodological solutions and agility is challenging. Statistics NZ has taken advantage of well-developed IT environments and clear strategic directions in terms of statistical architecture to develop and implement production systems that support the organisation's goals. Production systems are composed of standard methods, tools and processes. Outputs that use similar production methods are processed on common platforms. The platforms also offer analysts the opportunity to create new production systems without the help of IT teams. The new platforms have encouraged standardisation and provide methods and tools that can be used to process and analyse data collected from traditional sample surveys or from an administrative source. When processing large volumes of data, the focus is on error reduction and automation of standard methods for each of the steps in the business process model. Centralised governance systems and a constructive culture of innovation make these changes possible by creating an environment conducive to managing change.
Towards an international framework for statistical councils of national statistical systems
Authors: Alldritt Richard
Published: January 2025

The number, variety and importance of statistical council bodies at national level has continued to grow over the years since this trend was recognised in the UN Handbook of Statistical Organization ^1 in 2003. This article brings together some ideas and arguments about the role and future of such bodies, as presented at a Special Topic Session on this theme at the World Statistics Congress in Hong Kong in August 2013.

The article summarises the main points from three papers presented at the session, each of which approaches the topic from a different perspective, and offers some further observations and conclusions. As well as the three contributing authors identified in the article, particular thanks are due to Margarita Guerrero, Director of the Statistical Institute for Asia and the Pacific who acted as discussant for the session.

Whilst the discussion at the WSC session tended to reject the concept of an internationally agreed set of standards that a statistical council body should demonstrate in order to achieve international recognition as a national statistical council, there was nonetheless wide support for an open dialogue between such bodies to share information about their roles and experience.
Challenges of data collection in developing countries – the Pakistani experience as a way forward
Authors: Elahi Asad
Published: January 2025

In developing countries like Pakistan data collection is restricted to state institutions. These state based statistical departments face internal as well as external problems. The internal problems include lack of institutional setup and weak infrastructure while the external ones are the low literacy ratio as well as lack of awareness regarding the data collection. However in order to address these problems the traditional approach is insufficient and hence a nuanced approach is needed which is also the prime focus of the paper. This includes providing autonomy to the statistics department, decentralization of data entry, and training of the statisticians, standardization of statistics as well as implementation of PARIS21 recommendations. The paper addresses some of the measures taken by Pakistan like the creation of the Statistical Training Institute, which might be useful in context of other developing countries.
Informing the nation – open access to statistical information in Australia
Authors: Tam Siu-Ming
Published: January 2025

The Australian Bureau of Statistics (ABS) has a legislative, and a strongly held organisational commitment to the Australian community to publish the results of all statistical collections that it conducts, and make them accessible by all. In 2005, the ABS introduced free statistics on the ABS website. Since then, there has been exponential growth in the on-line access of ABS statistics. Aiming to take advantage of the opportunities available from Web 2.0 technologies, in late 2008, the ABS adopted Attribution 2.5 Australia licence of Creative Commons. This initiative is expected to lead to better decision making through high value-added information products created by re-using, sharing, mixing and matching of ABS data with other data sets.

Release of European Union microdata, ESS projects on remote access
Authors: Bujnowska Aleksandra , Museux Jean-Marc
Published: January 2025

This paper outlines microdata access methods at the European level, and specifically to data governed by European Union (EU) Regulation 831/2002 or where explicit approval of the EU Members is given on the access to particular datasets via Eurostat safe centre.

Access to EU microdata for research purposes was enabled in 2002 when the Commission Regulation (EC) No 831/2002 came into force. Since then more than 100 contracts have been signed each year with research organisations for the provision of microdata for scientific purposes. The current Regulation foresees two ways of access to microdata: access to anonymised microdata files, and access to confidential data in the safe centre in Eurostat premises in Luxembourg.

The first part of the paper outlines the legal framework at the EU level. The second part discusses the different modes and conditions of access as well as practical issues related to access to microdata in general. The final part provides an overview of the projects currently carried out in the domain of remote access at the European level.

The situation with regards to the access to EU microdata will evolve in the near future with the new regulatory framework and subsequent changes in the governance structure for statistical confidentiality in the European Statistical System.
Supporting research and protecting confidentiality. ABS microdata access: Current strategies and future directions
Authors: Tam Siu-Ming , Farley-Larmour Kim , Gare Melissa
Published: January 2025

Access to microdata for social and economic research and analysis is a key part of the Australian Bureau of Statistics (ABS) mission to encourage informed decision making, research and discussion. Since 1985, the ABS has been making microdata available for statistical purposes in the form of Confidentialised Unit Record Files (CURFs).

Microdata use is governed by the requirement to protect respondent confidentiality, as enshrined in the Australian Census and Statistics Act 1905. Confidentialisation of the data prior to its release is the foremost ABS strategy to protect respondent confidentiality.

To date, ABS policy provides that the most highly confidentialised Basic CURFs are available through the least controlled CD-ROM mode; the more detailed Expanded CURFs are accessible through the more controlled Remote Access Data Laboratory (RADL); and the most detailed Specialist CURFs are available only through the ABS Data Laboratory (ABSDL) in ABS Offices.

In 2009 ABS commenced a long term project that will meet user demand for access to more detailed unit record data, across a wider array of datasets and through means that are more flexible than the current services. Development of a Survey Table Builder is underway, to be followed by a new microdata analysis service.
How relevant are the United Kingdom's official measures of price change?
Authors: Ward Michael , Blades Derek , Carson Carol
Published: January 2025

This paper argues that the official price indices currently available for the United Kingdom are misleading the general public and are of doubtful relevance for policy purposes. This is not an ethical issue in the sense that government statisticians or politicians are deliberately misleading the British public about inflation. What has happened is that the statisticians have given more weight to questionable economic theory than to the public's need for a clear and transparent measure of price inflation. The end result is that politicians may make bad decisions because they are using bad statistics and the general public loses faith in the statisticians because of the gap that they see between their own daily shopping experience and the official measure of inflation.
Ethics, laws and practices dealing with the protection of confidentiality of statistical data: Some experiences from Spain
Authors: Martín-Guzmán Pilar , Villán Ildefonso
Published: January 2025

Confidentiality is one of the basic pillars sustaining public trust in official statistics, and has a prominent place in all declarations of ethical principles. Rules for the preservation of confidentiality in Spain go back as far as 1787. The legislation protecting these rules has evolved under the influence of the political changes undergone by the country since then. In particular, the establishment of a democracy in 1978, and the adoption of a Constitution, after forty years of a totalitarian government, stimulated significant changes in the legislation on statistical confidentiality. New laws on the Protection of Personal Data were also passed in 1992. Also, Spain is since 1986 a European Union (E.U.) Member State, and is consequently subject to the E.U. regulations on confidentiality and data protection. This paper reviews the current legislation and practice on confidentiality in Spain, and its incidence in statistical operations. The challenges arising, in connection with confidentiality issues, from the specific political organisation of the country are also described, as well as the connections between the Statistical Act and the Laws on Personal Data Protection and the cooperation schemes between the Statistical Office and the Data Protection Authority. The paper also includes some comments on specific confidentiality issues related to operations that, although implemented by the National Statistical Office, are not regulated by the Statistical Act, and the solutions that have been adopted in order to deal with them are described. Some conclusions follow.

Published: January 2025

Context and objective: In France, national estimates of the incidence of cancers are based on mortality data by extrapolating the ratio between observed incidence and mortality in areas covered by cancer registries. The objective of this study is to determine the interest of using the discharge abstracts database gathered in hospitals to estimate breast cancer incidence in two French departments: Côte d'Or and Doubs.

Methods: This study concerns the incident breast cancer cases identified in 2004 and 2005 through Côte d'Or and Doubs cancer registries and potential incident breast cancer cases selected through two algorithms in the Medical Information System Program(PMSI – Programme de Médicalisation des Systèmes d'Information) databases. The value of these algorithms was evaluated by probabilistic linkage between data from the anonymous registry and from the PMSI.

Results: The first algorithm provides an estimated incidence close to those given by registries, and has a good sensitivity and positive predictive value; the second algorithm overestimates the incidence by about 100%, and has a poor positive predictive value.

Conclusion: This study shows the usefulness of the PMSI databases and underlines the interest and difficulties of using these data to estimate cancer incidence. The PMSI database cannot be used as a unique source to estimate breast cancer incidence.
Conceptual thinking in national statistics offices
Authors: Forbes Sharleen , Brown Denise
Published: January 2025

This paper attempts to define the conceptual thinking skills needed by staff producing statistics within a National Statistics Office. The overarching concepts of responsibility or utility that are specific to official statistics are discussed as well as what is needed to understand or develop the conceptual and measurement frameworks that form the basis of official statistics. It is argued that conceptual thinkers not only need to be able to translate the real world into models that simplify reality and make it measurable for statistical purposes but they also need to be able to reason with statistics and communicate what they mean to others. Conceptual thinking and the skills needed to create new conceptual frameworks are developed primarily through experience which can be accelerated by exposure to those conceptual frameworks already in use and provision of opportunities to `practice' the process of developing conceptual frameworks. Survey specific concepts are not discussed except to illustrate some of our proposals.
Which Gene Combination to Test in Wet Lab? A Pedagogical Walkthrough of R Code Mechanics of ML-Based Search Engine for Biologists/Oncologists
Authors: Sinha Shriprakash
Published: January 2025

BACKGROUND: In biology/oncology, one is faced with the problem of exploring relevant unknown biological hypotheses in the form of a myriad of combinations of factors that might be affecting the pathway under certain conditions. If discovered, these are potential breakthroughs that could help understand the mechanism of cell biology, leading to scientific discoveries and therapeutic interventions. Currently, a major persisting problem is to cherry-pick the combinations based on expert advice, literature survey, or guesses for investigation. This entails investment in time, energy, and expenses at various levels of research.

RESULTS: To address these issues, a search engine design was recently published, which showed promise by revealing existing confirmatory published wet lab results. Additionally, and of import, an adaptation of the published engine mined up a range of unexplored/untested/unknown combinations of genetic factors in the cell signaling pathways that were affected by ETC-1922159 enantiomer, a PORCN-WNT inhibitor, after the colorectal cancer cells were treated with the drug.

CONCLUSIONS: Here, a pedagogical walkthrough of the R code of the machine learning-based search engine is elucidated. This will help biologists/oncologists to locate gene combinations ranked/revealed by using the advanced machine learning-based search engine, instead of wandering in a vast combinatorial forest and later testing the combinations of choice in a wet lab. The article ends with an example of a ranking of a \(3^{rd}\) order combination that has recently been established in another wet lab experiment.
SafeSynthDP: Leveraging Large Language Models for Privacy-Preserving Synthetic Data Generation Using Differential Privacy
Authors: Nahid Md Mahadi Hasan , Hasan Sadid Bin
Published: January 2025

Machine learning (ML) models frequently rely on training data that may include sensitive or personal information, raising substantial privacy concerns. Legislative frameworks such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) have necessitated the development of strategies that preserve privacy while maintaining the utility of data. In this paper, we investigate the capability of Large Language Models (LLMs) to generate synthetic datasets integrated with Differential Privacy (DP) mechanisms, thereby enabling data-driven research and model training without direct exposure of sensitive information. Our approach incorporates DP-based noise injection methods, including Laplace and Gaussian distributions, into the data generation process. We then evaluate the utility of these DP-enhanced synthetic datasets by comparing the performance of ML models trained on them against models trained on the original data. To substantiate privacy guarantees, we assess the resilience of the generated synthetic data to membership inference attacks and related threats. The experimental results demonstrate that integrating DP within LLM-driven synthetic data generation offers a viable balance between privacy protection and data utility. This study provides a foundational methodology and insight into the privacy-preserving capabilities of LLMs, paving the way for compliant and effective ML research and applications.
Los avatares emocionales de Thatgamecompany: la conexión humana digital a través de los mundos video lúdicos
Authors: Ruiz Cañero Adrian
Published: January 2025

Poseemos una imagen mental preconcebida sobre lo que es un avatar, una especie de marioneta digital que se suele personalizar a nuestro gusto o semejanza, para recorrer un entorno virtual a través de una pantalla. Este discurso, aplicable a los videojuegos y a las diferentes identidades digitales que nos rodean, suele centrarse en esos dos pilares de la personalización estética y la creación de unos entes digitales más realistas. Pero ¿qué sucede cuando enfocamos la experiencia en lo emocional, en las conexiones humanas que nos permiten realizar? Esta investigación examina el concepto proporcionado por la compañía desarrolladora Thatgamecompany, siendo un caso específico y único, que explora al avatar desde lo emocional y pretende crear un impacto inolvidable en la experiencia del jugador.
Flower (2009), Journey (2012) o su más reciente obra Sky: Children of the Light (2019), ponen en los mandos de los jugadores unos avatares minimalistas, casi conceptuales, que, combinados con unos movimientos fluidos y unos gestos sutiles, que hacen entrar al usuario en un estado que han denominado “flow”, para que desgranen una emotiva narrativa envuelta con una sensible banda sonora en todos sus juegos. Así convierten a sus avatares en un potente vehículo emocional, que fomentan además encuentros anónimos con otros jugadores en línea, donde la comunicación se basa en gestos en lugar de palabras. Estas breves y casi efímeras interacciones crean sin embargo profundos momentos de conexión y colaboración, trascendiendo cualquier barrera cultural o de lenguaje.
Estas obras emocionales encarnan con sus personajes la vulnerabilidad y la soledad del viaje, invitando a los jugadores a una búsqueda interior de su propio significado, recorriendo el camino hasta el objetivo final del juego. La interacción anónima con otros jugadores, fuerza el sentido de comunidad y apoyo mutuo, recordándonos la importancia de la conexión humana incluso en los entornos digitales más abstractos. A través de esos bellos pero impresionistas paisajes, el viaje interior del jugador con su avatar, permite explorar temas universales como la pérdida, la esperanza y la trascendencia. Todo esto se ha potenciado en su última obra, Sky, donde su mundo persistente otorga desafíos comunitarios y eventos para dar sentido a la narrativa que subyace en la experiencia.
Por tanto, el análisis para esta investigación se centra en cómo los elementos de sus juegos (diseño, narrativa y mecánicas) contribuyen a la creación de una experiencia emocionalmente significativa, facilitando las interrelaciones humanas sencillas pero únicas, tratando temas universales a través de dichos personajes digitales, que no son más que una extensión de nuestro propio ser.

Authors: Togatorop Andreas , Lahay Ratna Rosanty
Published: January 2025

The age of transplanting is quite important in the cultivation of mustard greens. This research aims to know the best transplanting, which was carried out on farmer's land in Tanjung Sari Village, Medan Selayang District, Medan, North Sumatra with an altitude of about 25 meters above sea level (masl) starting from February to April 2023. This study used a factorial randomized block design (RBD) which consisted of 2 factors: factor 1 was the age of transplanting (U) which consisted of 3, namely: U1 = 10, U2 = 15, U3=20 DAS (Day After Sowing). Factor2 wasthe addition of the type of organic fertilizer (O), which consisted of 4, namely: O0=Soil, O1=Soil+Kacing Fertilizer (25 tons/ha or 62.5 grams/polybag), O2=Soil + Chicken Manure (25 tons/ ha or 62.5 gram/polybag), O3=Soil+Cow Manure (25 ton/ha or 62.5 gram/polybag). The results showed that the best transplanting age was 20 DAS which was significantly different from the other treatments on the parameters of plant length, number of leaves, diameter of pseudo stems, and weight of biomass per sample. The best organic fertilizer in this study was chicken manurewhich was not significantly different from vermicompost fertilizer and had asignificant effect on the parameters of plant length, number of leaves, pseudo stem diameter, and weight of biomass per sample. The best treatment interaction was obtained in the combination treatment of transplanting 20 DAS with the application of vermicompost fertilizer which had the highest pseudo stem diameter.

Authors: Erwina Surbakti  , Irsal
Published: January 2025

Several climate components influence the decline and rise in tea plant productivity. This research aims to determine the influence of climate elements on the productivity of tea plants in the Bah Butong PTPN IV plantation. The hypothesis in this research is that there is a real influence of rainfall, rainy days, amount of sunlight, temperature, and humidity partially or simultaneously and their correlation on tea productivity. This research was carried out from September 2023 to December 2023 using data collection methods through field surveys with secondary data collection at related agencies. The data taken includes rainfall data, rainy days, amount of sunlight, temperature and humidity as well as tea production. The analysis method used is multiple linear regression analysis and correlation analysis using SPSS.v.22 for Windows. The results of the partial t-regression analysis show that rainfall and temperature have a significant effect, while rainy days, amount of sunlight, and humidity have no significant effect and simultaneously rainfall, rainy days, amount of sunlight, temperature and humidity has no significant impact on increasing tea production. The correlation of rainfall, rainy days, amount of sunlight, temperature and humidity on tea plants has a weak and very weak influence on the interpretation of the r value in achieving tea productivity.

Published: January 2025

The abundance of biomass in Indonesia can be a big threat if not managed properly with the principle of carbon retention. The loss of large amounts of carbon into the air in the form of C02 has become a concern for the increase in global temperatures. Biochar is one of the solutions to maintain carbon on earth for a long period of time. Biochar is an amendment that today has been around the world for more than 10 years, and has been the subject of many studies, the quality of biochar is highly determined by the techniques used. The manufacture of biochar is the same as the manufacture of charcoal but there is a slight difference other than in its utilization, because the manufacture of charcoal uses 1 technique of making biochar. The Pyrolysis method is a method of making biochar, and the technique is 2 ways, namely by using Kiln and Retort. The Klin technique is a heating technique with a heat source coming from the material itself, namely combustion with limited oxygen, while the heating retort with a heat source is not from biomass but from other sources.

TUTELA DA DIGNIDADE LGBTQIAPN+
Authors: Souza Poliana Tomaz , Pamplona Laura Rodrigues Paim
Published: January 2025

Este artigo aborda a proteção da comunidade LGBTQIAPN+ sob os princípios bioéticos, consentâneo aos papéis do Supremo Tribunal Federal, na defesa dos direitos e garantias fundamentais para a ordenação de uma vida boa. Também destaca a resistência dos demais poderes republicanos no combate à intolerância, opressão e violência praticados em desfavor deste grupo identitário. Para tanto, buscando compreender as decisões do STF, dada a persistência de crimes, foi feita uma revisão bibliográfica, incluindo legislações e decisões do STF sobre a necessidade de mandados protetivos garantidores para a comunidade LGBTQIAPN+. Neste lume, destaca-se o papel da Corte Constitucional brasileira no reconhecimento de direitos básicos, como a união estável homoafetiva, a equiparação de regimes sucessórios, a alteração de nome e sexo de pessoas transgênero no registro civil de pessoas naturais, desvencilhado de procedimentos cirúrgicos, a criminalização da homofobia e transfobia como crimes de racismo, a permissão para divulgação de materiais e ensino sobre gênero e orientação sexual, e a discussão sobre o uso da linguagem neutra. Em epítome, destaca-se a importância de se recorrer às perspectivas kantiana e bioética no desenvolvimento de ações encadeadas para a proteção da comunidade LGBTQIAPN+, a necessidade de popularizar a atuação do Ministério Público como órgão instrumental de políticas de valorização da diversidade, e a elevação da dignidade substantiva.

Los ríos profundos es considerada una de las obras más hermosas de la literatura no únicamente hispanoamericana sino universal. En este caso se interrelaciona otro elemento igualmente hermoso en la vida del hombre: la poesía, específicamente el yo poético, con la intención de demostrar que éste está presente a través de dos elementos: uno que la novela es autobiográfica, y otro que el quechua juega un rol interesante en cuanto a manera de comprender la vida.

W publikacjach dotyczących pracy zdalnej brakuje badań dotyczących postrzegania jej przez pracowników z Pokolenia Z, co stanowi problem dla nauki i praktyki oraz oznacza, że w tym obszarze występuje luka badawcza. Celem artykułu jest określenie postrzegania przez przedstawicieli pokolenia Z w Polsce wad pracy zdalnej. W badaniu sformułowano następujące pytania badawcze: Które wady pracy zdalnej według pracowników z pokolenia Z w Polsce można uznać za najważniejsze w kontekście zainteresowania wykonywaniem tej formy pracy? W jakie grupy można połączyć wady pracy zdalnej z perspektywy pokolenia Z? Realizację obranego celu oraz udzielenie odpowiedzi na pytania badawcze umożliwiły: przegląd literatury, przeprowadzone badanie ankietowe oraz zastosowanie wybranych instrumentów analizy statystycznej. Próba badawcza została dobrana w sposób celowy.
Z przeprowadzonego badania wynika, że badani przedstawiciele pokolenia Z za największe wady pracy zdalnej uznali: wzrost stresu, świadomość braku fizycznej interakcji, izolację, niewystarczającą infrastrukturę techniczną, konieczność samodzielnego wykonywania zadań przy braku bezpośredniego wsparcia, a także zachwianie równowagi pomiędzy pracą i życiem prywatnym. W wyniki analizy uzyskanych danych wady zostały zaliczone do trzech grup: stanowiących o istocie pracy zdalnej, efektywności jej zorganizowania przez zarządzających oraz związanych z jej bieżącą realizacją.

Objective

This study aimed to develop and validate a nomogram for predicting the risk of 3 months adverse outcomes among young adults with acute ischemic stroke (AIS).

Methods

Patients aged between 18 and 50 with acute ischemic stroke (AIS) at the Shenyang First’s People Hospital, between January 1st 2017 to May 30th 2023 were included in this retrospective study. The primary outcome was a three-month unfavorable outcome, evaluated with modified Rankin Scale (mRS > 2). Univariate logistic regression was used to select the independent factors of prognosis and multivariate logistic regression to establish a new nomogram model. We used the area under the receiver-operating characteristic curve (ROC) to evaluate the discriminative performance and used the calibration curve with Hosmer-Lemeshow goodness of fit test to assess the calibration performance of the risk prediction model. Decision curve analysis (DCA) was applied to assess the clinical utility of the nomogram.

Results

A total of 1,015 patients were enrolled. Gender (male vs. female; Odds ratio[OR], 0.5562[95% Confidence Interval (CI), 0.3104–1.0478]; p = 0.053), family history of stroke (OR, 3.5698[95%CI 1.5632–8.0329], p < 0.001), prior stroke (OR, 2.1509[95%CI 1.2610–3.6577], p < 0.001), previous heart disease (OR, 3.4047[95%CI, 1.7838–6.6976], p < 0.01) toast type (cardio-embolism stroke vs. large-artery atherosclerosis (LAA), OR, 0.0847[0.0043–0.5284], p < 0.01), toast type (stroke of undetermined etiology vs. LAA, OR, 0.0847[0.0439–0.5284], p < 0.01), mRS at admission (OR, 15.2446 [9.1447–26.3156], p < 0.0001), adherence to medication (OR, 2.1197[95%CI, 1.1924–3.7464], p < 0.001), systolic blood pressure (SBP; OR, 1.0145[1.0041–1.0250], p < 0.001), and lactate dehydrogenase (LDH; OR, 1.0060[1.0010–1.0111], p < 0.01) were related to 3 months adverse outcomes among young adults with AIS. The nomogram displayed excellent calibration and discrimination. DCA confirmed the clinical applicability of the model.

Conclusion

The nomogram comprised of gender, family history of stroke, prior stroke, previous heart disease, toast type, mRS score at admission, adherence to medication, SBP and LDH may predict 3 months adverse outcomes among young adults with AIS.

Microglia, the immune cells of the central nervous system, activate neuroinflammatory pathways in response to homeostatic disturbances, a process implicated in the pathogenesis of various neurodegenerative diseases. Emerging evidence identifies abnormal microglial activation as a causal factor at the onset of peroxisomal leukodystrophies, including X-linked adrenoleukodystrophy (X-ALD). This study investigates how primary peroxisomal deficiencies influence oxidative properties of microglia and examines the subsequent impact on neurons and oligodendrocytes. Using BV-2 microglial cells lacking ABCD1, ABCD2, or ACOX1, peroxisomal proteins that play key roles in the very-long-chain fatty acid beta-oxidation, we analyzed their response under basal condition and after stimulation by lipopolysaccharide (LPS). Transcriptomic analysis of the mutant microglial cells revealed numerous differentially expressed genes, particularly in redox-related pathways following LPS exposure. These changes are consistent with the increased production of reactive oxygen species (ROS) and nitric oxide (NO). Conditioned media (CM) from the mutant cells were then applied to cultures of neuron and oligodendrocyte cell lines. Exposure to CM from LPS-stimulated mutant microglial cells significantly increased apoptosis in both cell types. Furthermore, treated neurons exhibited a reduction in cell complexity and an increased ability to secrete neuropeptides. These findings demonstrate that peroxisomal impairments in microglia exacerbate inflammatory response and ROS/NO production, affecting the survival of neurons and oligodendrocytes, as well as neuronal morphology and function. This dysfunction might contribute to the early neurodegenerative events in X-ALD by triggering and sustaining neuroinflammatory cascades. Therapeutic strategies that target microglial activation and secretion profiles could hold promise in managing peroxisomal disorders such as X-ALD.

Published: January 2025

Background

Water, coffee and tea are the primary sources of daily hydration. However, the sex-specific relationship between these beverages and cardiovascular disease (CVD) among remains unclear.

Methods

In total, 210,239 men and 251,383 women from the UK Biobank were included. The consumption of water, coffee and tea were self-reported. CVDs, including coronary heart disease (CHD), stroke and heart failure (HF) were followed till March 1st, 2023. Sex-specific Cox models were utilized to evaluate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations.

Results

During a median follow-up of 8.7 years, 11,098 (2.40%) participants developed new-onset HF, 33,426 (7.24%) participants developed new-onset CHD, and 9,706 (2.10%) participants developed new-onset stroke. After adjustments, higher water consumption was generally associated with reduced risk of CVDs among both men and women. In contrast, heavy coffee consumption (particularly ≥6 cups/day) was associated with a greater risk of HF [1.16 (1.03–1.31) in men vs. 1.25 (1.12–1.40) in women], a greater risk of CHD [1.27 (1.18–1.36) in men vs. 1.21 (1.14–1.29) in women] and a greater risk of stroke [1.13 (0.99–1.29) in men vs. 1.20 (1.03–1.31) in women]. Similarly, heavy tea consumption was associated with an increased risk of HF (men: HR 1.19 [1.08–1.31]; women: HR 1.12 [1.02–1.23]) and CHD (men: HR 1.12 [1.05–1.18]; women: HR 1.18 [1.12–1.24]).

Conclusion

Our study revealed that water consumption was associated with a lower risk of CVDs, with a lower risk of CVDs, while heavy coffee or tea consumption was linked to a higher risk. Notably, coffee and tea consumption partially attenuated the protective association of water intake with CVDs. Furthermore, significant sex differences were observed in the associations between coffee or tea consumption and CHD incidence.
