ВЛИЯНИЕ КОМПЛЕКСНОЙ ХИМИКО-ТЕРМИЧЕСКОЙ ОБРАБОТКИ НА КОРРОЗИОННУЮ СТОЙКОСТЬ СТАЛЬНЫХ ИЗДЕЛИЙ
Authors: Соколов Александр Григорьевич , Бобылёв Эдуард Эдуардович , Марченко Вячеслав Дмитриевич
Published: October 2023

В статье рассматривается влияние комплексной химико-термической обработки (КХТО) стальных изделий, включающей в себя цементацию, диффузионное насыщение хромом и закалку на коррозионную стойкость стальных изделий в 30% водном растворе HCl и 3% NaCl. В качестве обрабатываемых материалов использовались стали Ст3, 40Х, 40Х13, 20Х13. Было выявлено, что КХТО позволяет получать покрытия толщиной от 7 до 27 мкм, при этом микротведрость поверхности покрытых образцов достигает 24000 МПа в зависимости от температуры КХТО. Было выявлено, что на скорость коррозии влияет элементный состав покрываемого материала, режимы КХТО, состав коррозионно-активной среды. Проведение испытаний образцов выявило, что стали без покрытий имеют более низкую коррозионную стойкость, чем материалы, подвергнутые КХТО. При этом, скорость коррозии материалов снижается пропорционально увеличению содержания хрома в и снижению содержания углерода в покрываемом материале. Наиболее эффективно скорость коррозии снижается в среде NaCl. Так, скорость коррозии образцов, изготовленных из стали Ст3, снизилась в 11,6 раз, из стали 40Х в 8,22 раза, 40Х13 в 4,56 раза, 20Х13 в 4,1 раз. В 30% водном растворе HCl скорость коррозии образцов, изготовленных из стали Ст3, снизилась в 4,6 раз, из стали 40Х в 4,4 раза, 40Х13 в 3,99 раз, 20Х13 в 3,84 раза. Также, было выявлено, что на коррозионную стойкость оказывает влияние температура КХТО. Так, при температуре КХТО 1000°С скорость коррозии в 3 % NaCl составляла 0,08 г/(м2*час). При увеличении температуры до 1070°С скорость коррозии уменьшалась до 0,059 г/(м2*час). Аналогично температура КХТО влияла и на другие исследуемые материалы.
Fixing flavins: hijacking a flavin transferase for equipping flavoproteins with a covalent flavin cofactor
Authors: Tong Yapei , Kaya Saniye , Russo Sara , Rozeboom Henriette , Wijma Hein , Fraaije Marco
Published: October 2023

Most flavin-dependent enzymes contain a dissociable flavin cofactor. We present a new approach for installing a covalent bond between a flavin cofactor and its hosting protein. By using a flavin transferase and carving a flavinylation motif in target proteins, we demonstrate that ‘dissociable’ flavoproteins can be turned into covalent flavoproteins. Specifically, three different FMN-containing proteins were engineered to undergo covalent flavinylation: a light-oxygen-voltage (LOV) domain protein, a mini singlet-oxygen-generator (miniSOG), and a nitroreductase (BtNR). Optimizing the flavinylation motif and expression conditions led to covalent flavinylation of all three flavoproteins. The engineered covalent flavoproteins retained function and often exhibited improved performance such as higher thermostability or catalytic performance. Crystal structures of all three covalent flavoproteins confirmed the designed threonyl-phosphate linkage. The targeted flavoproteins differ in fold and function, indicating that this method of introducing a covalent flavin-protein bond is a powerful new method to create flavoproteins which cannot lose their cofactor, boosting their performance.

Published: October 2023

The article discusses the essence and distinctive features of marketing activities of an enterprise operating in the service sector, demonstrates the need to study its specifics, as well as analyze the marketing tools used. Marketing is a system of organizing and managing the production and sales work of an enterprise, analyzing the market in order to develop and meet the demand for products and services, as well as generating income. The main principles follow from the essence of marketing, namely, taking into account the needs of the market, the state and dynamics of demand, as well as market conditions when making economic decisions, creating conditions for adapting production to market conditions, to the structure of demand, influencing the market, the consumer, along with supporting all available means, primarily advertising. To date, the main task of the company's marketing activities in the service sector is to attract the maximum number of customers, which is achieved through a well-thought-out promotion program.

The ability to predict further development prospects, determine tactics and develop strategies is one of the main sources of building a new type of enterprise activity. A significant number of strategic developments are carried out on the basis of marketing decisions. At the present stage, such types of marketing as traditional (external) marketing, internal marketing and interaction (relationship) marketing are used in the service sector. The service market successfully uses both traditional and innovative marketing tools, primarily various internet technologies. The company's own website, presence in social networks, use of chatbots and video blogs is a necessary prerequisite for promoting services and attracting as many customers as possible. In addition, it is concluded that the problem of the effectiveness of marketing activities of organizations is also becoming more and more relevant for non-production organizations.
Examining the Effects of a Group-Based Educational Intervention on Young People’s Understanding of Legal Rights in New Zealand
Authors:   , Stewart Kennedy
Published: October 2023

In New Zealand, when a young person is arrested, detained, or questioned by a police officer, they must first be informed of their legal rights with police via the Child/Young Persons version of the New Zealand Rights Caution (New Zealand Police, 2011). Research has found young people do not have a complete understanding of their legal rights (e.g., Gaston, 2017; Grisso, 1980; Rogers et al., 2014; Strachan, 2008), which may be attributed to the fact that legal rights are not delivered in a developmentally appropriate way (Rogers et al., 2008; Ryan, 2020). This thesis explored two key research questions: 1) What is the level of legal rights understanding among young people in New Zealand? and 2) can their understanding be improved by participating in a group-based educational intervention? The sample consisted of 62 young people (aged 12 – 15 years) who had been recruited through high schools and community groups in the North Island of New Zealand. Young people were quasi-randomly assigned to one of two conditions. The first condition was exposed to the Child/Young Person’s version of the New Zealand Rights Caution, and the second condition received a group-based educational intervention about their legal rights. Subsequently, participants were assessed on their legal rights understanding using an adapted version of the New Zealand Rights Caution Competency Questionnaire (Fortune et al., 2017). Results showed young people had gaps in their understanding and held several misconceptions about their legal rights. The educational intervention led to significant improvements in some aspects, such as young people’s ability to define legal terms and comprehend key statements in the Child/Young Persons version of the New Zealand Rights Caution. Such results indicate the use of a group-based educational intervention may enhance young people’s legal rights understanding, but also that there are other contributing factors. The implications of this study’s findings for policy and practice are considered, as are recommendations for future research in this field.

Published: October 2023

Objective: To explore the pathologic response rate to primary progesterone treatment in patients with Endometrial Intraepithelial Neoplasia (EIN) and early-stage endometrioid-type Endometrial Adenocarcinoma (EAC). Methods: Retrospective chart data were collected for patients with either EIN or EAC receiving primary progesterone treatment between 2015 and 2022. The presence of complete or partial response, time to response, and other demographic and treatment factors were recorded to determine independent predictors of response to progestin treatment. Results: In total, 112 women who were diagnosed with EIN or EAC were treated with upfront progestin therapy, of whom 79 had sufficient follow-up to assess response. Fifty patients (63%) responded, of whom 10 (20%) ultimately relapsed. Response was more robust among patients with EIN (79%, n = 33) compared with patients who had cancer (46%, n = 17). The median time to respond was 5.8 months overall. Diagnosis of EIN, younger age at diagnosis, and any pathologic evidence of progesterone effect were all predictors of treatment response. Younger patients had a significantly shorter time to partial or complete response with a median time to response of 5.9 months in patients ≤ 45 and 13.8 months in patients > 45. Conclusion: Our study demonstrated a lower overall response rate (63%) than reported in previous studies, especially for patients with cancer (46%). Younger patients had a significantly shorter time to respond than older patients. Pathologic progesterone effect observed at any time during treatment was a significant predictor of treatment response regardless of diagnosis and could serve as an early predictor of response to therapy.
Rediscovering Aleck: The Forgotten Origins and Memorial History of a Fictional Slave Sale Advertisement
Authors: Breeden Edwin C.
Published: October 2023

Abstract: This article examines the fictional origins of a widely reproduced broadside for an 1852 slave auction in Charleston, South Carolina, that has for the last century been accepted as an authentic relic of the slave trade. Close analysis of the document's content and the local history of Charleston reveals numerous discrepancies that establish the document's inauthenticity and illustrate the value of basic corroboration and contextualization to historical inquiry. Tracing the document's actual origins to an 1892 fictional illustration, the article shows how its long career as an object of historical memory can shed light on the shifting and contested ways in which Americans have remembered the role of slavery and African Americans in the nation's past.
Slavery, Collective Memory and the Urban Landscape: The Rise, Fall and Rise of Liverpool's Statue of William Huskisson
Authors: Millington Richard
Published: October 2023

Abstract: In 1982, residents of Liverpool pulled a statue of William Huskisson from its plinth. Today, a plaque at the site states that the sculpture was removed by "activists offended at Huskisson's role in supporting slavery." Less than a mile away, however, one finds Huskisson's effigy, reerected, with no reference to slavery. This article traces the history of the rise, fall and rise of the Huskisson statue in order to examine how collective memory shapes the urban landscape and informs local communities' interaction with it. It also reflects on the nature of memory conflicts and the processing of unresolved events in the past.

Joyce, Nussbaum, and the Value of Disgust
Authors: Eichholz Patrick
Published: October 2023

Abstract: James Joyce's Ulysses is a famously obscene novel. What is the purpose and emotional effect of the novel's obscenity? In court, Morris Ernst defended Ulysses as an emotionally static work of high art that was only to be accessed intellectually. After the legal battle had been won, critics became more forthright about the novel's broader emotional appeal. Martha Nussbaum ends Upheavals of Thought (2001) celebrating Ulysses as the apotheosis of an aesthetic tradition progressing toward the frank acknowledgment of all our everyday emotions—all except for disgust. A central tenet of Nussbaum's theory of the emotions is that disgust is per se morally suspect. Joyce, however, admitted that he had disgusted himself writing Ulysses , a novel that demonstrates the hidden value of our most irrational emotion.

Stable soil is needed in a construction development. There are many ways and materials that can be used to improve soil properties that are less stable. Sulfur as one of the natural products in Indonesia has not been used optimally in the field of civil engineering, especially geotechnical engineering. Therefore, in-depth research is needed regarding the benefits of this sulfur in the world of civil engineering. The purpose of this study was to find out how the effect of mixing sulfur on the shear strength of the soil in the direct shear strength test and to find out at what ratio the sulfur mixture produced the greatest soil shear strength. This research was conducted on chemically stabilized soil samples in the form of addition of sulfur with various mixture variations. The results showed that the addition of sulfur at the percentage of 2%, 3% and 5% increased the cohesion value of the soil compared to the original soil. The addition of sulfur with a percentage of 6% and 7% decreases the soil cohesion value. The greatest increase in soil cohesion occurred in the 2% mixture with an increase of 86.95%. The percentage of 2% increases the value of the largest soil shear strength which is equal to 52.953 kPa from the original soil shear strength value of 48.716 kPa.

The implementation of monitoring the performance parameters of the PLTS system in several regions is still done manually so that the data obtained is also limited. In this study the PLTS monitoring system is based on Arduino Uno so that monitoring on PLTS can be monitored with telegram media. The monitoring system has two inputs, namely for PV and for the battery. To monitor the value of the electrical energy parameter, the INA219 sensor is used. The sensor reading results are displayed on the 16x2 LCD and mobile phone by sending the "STATUS" message command to the ESP8266 wifi module. Retrieval of current and voltage data on INA219 sensor readings and standard measuring instruments is carried out every 5 minutes. The system can monitor via an Android smartphone using Telegram. The test results show that the Telegram application can display and monitor photovoltaic and batteries in real time. The average error during sensor monitoring at photovoltaic output is 0.16% for voltage and 1.25% for current. The sensor reading results have an average error when charging the battery of 1.36% for voltage and 2.04% for current. The characteristics of the results of this measurement meet the requirements of IEC standard no. 13B-23.

Province XYZ Government has several application systems to support financial management and reporting system like budgeting and treasury system, asset management system and accounting system. All systems are working separately which may cause data to exist only in one of those systems when another system is needed for those data. They need integration among those systems to have more beneficiaries from the systems. This research used Enterprise Application Integration (EAI) to confront the problem. We used data level integration to integrate the asset management system and accounting system and application interface level integration using APIs to integrate the budgeting and treasury system and accounting system. Our experiment results that data-level integration is simpler to develop than application interface-level integration. Application interface level integration needed more prerequisite requirements and is more difficult to develop but more flexible and secure to connect and integrate into another system. Our performance test shows that integration using APIs needs more resources and probably gives a problem when the text data that is interchanged is too big. When all systems are owned by one institution that does not need restricted security constraints, data level integration gave more benefit for institution system integration.

Published: October 2023

Acne is among the most common conditions encountered in dermatological practice. In recent decades, there has been an increase in severe, complicated forms of acne.
Objective — to analyze the factors that affect the deterioration of the clinical course of acne and stimulate the development of moderate and severe forms of acne.
Materials and methods. For 3 years (2020—2023) we monitored 95 patients aged 18 to 35 years (45 men and 50 women), suffering from moderate to severe forms of acne. Before starting treatment, all patients completed a special questionnaire developed by us and taking into account known trigger factors.
Results and discussion. Factors stimulating the transformation of mild acne into moderate and severe forms of the disease differ in groups of men and women. Among men, stress worsened the clinical course of dermatosis in 5 (11.1 %) cases, in women — in 9 (18 %). Among the factors that influenced the course of acne in women, we can distinguish the use of contraceptives 2 (4 %) and dysmenorrhea in 4 (8 %) people. 2 (4 %) patients clearly noted an improvement in the course of acne after withdrawal of contraceptives. Alcohol stimulated exacerbation of acne in 3 (6.7 %) men. Not sticking to the diet more often contributed to the exacerbation of acne in women — 9 (18 %), compared to only 6 (13.3 %) in men. A significant role in the stimulation of acne activity was played by irrational antibacterial topical therapy: 2 (4.4 %) men and 4 (8 %) women used topical drugs with clindamycin and erythromycin for a long time. There were cases of prolonged use of topical corticosteroids (for more than 3 months), which significantly worsened the clinical course of acne, in one case led to the development of steroid rosacea. 7 (14 %) women and 3 (6.7 %) men associated exacerbation of the disease with the intervention of a cosmetologist who did mechanical cleaning during the activation of acne. 5 (11.1 %) men and 3 (6 %) women were associated with worsening of the course of acne after SARS-CoV-2 infection. Also, the most common factor in acne exacerbation was self-medication: 7 (15.5 %) men and 6 (12 %) women. Some patients were unable to isolate any of the known trigger factors of acne: 9 (20 %) men, 3 (6 %) women.
Conclusions. The study made it possible to identify a number of factors that affect the severity of the clinical course of acne. The most common triggers were psycho-emotional stress (18.0 % of women and 11.1 % of men), diet disorders (18 % of women and 13.3 % of men), self-treatment (15.5 % of men and 12 % of women), the COVID-19 pandemic (11.1 % of men and 6.0% of women), the intervention of cosmetologists with irrational aesthetic procedures (6.7 % of men and 14.0 % of women). Thus, the identified trigger factors of acne have gender, nutritional, behavioral characteristics, which requires further study and development of algorithms for their elimination and correction.

Background: Pyroptosis-related genes (PRG) are closely associated with the progression and metastasis of hepatocellular carcinoma (HCC). The predictive power of PRGs could be used to assess the clinical outcomes of HCC. Methods: The Cancer Genome Atlas (TCGA) RNA-seq data and clinical information from patients with liver hepatocellular carcinoma (LIHC) were used to identify PRG with differentially expressed between HCC and normal samples. Univariate Cox regression, least absolute shrinkage and selection operator (LASSO) Cox method, and multivariate Cox regression analysis were used to develop a prognostic model that included three PRGs. Gene set enrichment analysis (GSEA) was performed to identify differential immune cells and their associated pathways. The expression of Gasdermin C (GSDMC) in the HCC samples was detected by western blotting, and the function of GSDMC in HCC proliferation and metastasis was detected by the Cell Counting Kit-8 (CCK-8), colony formation, cell invasion, and wound healing assays. Results: Of 52 PRGs, GSDMC, Bcl-2 homologusantagonist/ killer 1 (BAK1), and NOD-like receptor thermal protein domain associated protein 6 (NLRP6) were selected to establish a prognostic model. The model successfully differentiated HCC patients with varied survival in the TCGA training and test cohorts, as well as the International Cancer Genome Consortium (ICGC) validation cohorts. The risk score was proven to be an independent prognostic factor. In addition, we also reported a marked upregulation of GSDMC in HCC tissues, which could be induced by CD274 (PD-L1). Overexpression of GSDMC contributes to HCC cells invasion, proliferation, and migration. Conclusions: The three PRGs signatures containing GSDMC independently predicted HCC prognosis. As a new driver molecule, GSDMC could play a tumor-promoting role by facilitating HCC growth and metastasis.

Türk Yerel Yönetim Yapısında Kırsal Mahallelerin Sorunları
Authors: KAVUNCU Ayşe
Published: October 2023

1970’lerden itibaren ortaya çıkan yerelleşme bağlamında metropollerdeki yerel yönetim yapısının nasıl olması gerektiği önemli bir tartışma alanı haline gelmiştir. İlk yıllarda, tercihen çok aktörlü/parçalı bir yerel yönetim kademelenmesi öne çıkarken; kısa süre içerisinde yönetişimin bu temel anlayışı yerini tek ya da iki kademeli daha büyük ölçekli yerel yönetim yapısı ortaya koymayı amaçlayan yerel yönetimleri birleştirme/bütünleştirme anlayışına bırakmıştır. Türkiye de 1980’lerin başında ortaya koyduğu ilk büyükşehir belediye kanunundan itibaren tercihini yerel yönetimlerin birleştirilmesi/bütünleştirilmesinden yana kullanmıştır. Aralık 2012 tarihinde kabul edilen 6360 sayılı kanun ile bir kez daha büyükşehirlerde konsolidasyon gerçekleştirilmiş ve büyükşehirlerde kırsal yerleşim alanları (köy), büyükşehir belediyelerinin yetki alanlarının il sınırına kadar genişletilmesiyle kentsel yerleşim alanlarına (mahalle daha sonra kırsal mahalle) dönüştürülmüştür. Bu makalede, Türkiye’de büyükşehirlerdeki kırsal yerleşim alanlarının kentsel alanlarla birleştirilmesi ve bu dönüşümün yarattığı sorunlar tartışılmaktadır. Özellikle kırsal mahallelerin tüzel kişiliklerini kaybetmesi, ekonomik stratejilerin değişmesi ve kamusal hizmetlere ulaşımın zorlaşması gibi sorunlar vurgulanmaktadır. Ayrıca, kırsal alanların tespiti meselesi ve bunun sağlıklı bir şekilde yapılması gerekliliği üzerinde durulmaktadır. Bu süreçte kullanılan Mekânsal Adres Kayıt Sistemi'nin (MAKS) önemi belirtilirken, uluslararası düzeyde karşılaştırmaların yapılabilmesi için standart bir modelin kullanılmasının iç politika yapım sürecinde yetersiz kalabileceği vurgulanmaktadır. Bu nedenle her ülkenin kendi koşullarına uygun ek kriterler kullanması gerektiği ifade edilmektedir.
Lambert’in Erzurum Planı

Published: October 2023

Erzurum, Cumhuriyet dönemine geçişle birlikte imar planı yapılarak modern bir yapıya kavuşturulmak istenen kentlerimizdendir. 1939 yılında Fransız plancı J. H. Lambert tarafından yapılmış olan plan, bugüne kadar detaylarıyla incelenmemiş ve mekânsal kurgusu yeterince anlaşılmamış bir plandır. Bu çalışmada Lambert planının kentin günümüz dokusu üzerindeki etki düzeyi sorgulanmıştır. Plan görseli ve açıklama raporu irdelenerek planının kararları çözümlenmiş, ardından kentin bugünkü mekânsal yapısı ile eşleştirilmiş, plana uygun ve uygun olmayan gelişmeler belirlenmiştir. Analizler için veri toplama ve değerlendirme amacıyla belge inceleme (plan ve açıklama raporu), içerik inceleme ve gözlem (arazi kullanımı ve mevcut durum analizi) gibi alt yöntemler kullanılmıştır. Cumhuriyet döneminin tasarım ve planlama ilkeleri ile yüzyıllık dönemde gerçekleşen kentleşme süreçleri arasındaki ilişki ortaya konmuştur. Bulgular Erzurum’un kent merkezini şekillendiren temel unsurların bu plandan miras kaldığını göstermiştir. Bunlar, Cumhuriyet Caddesi, istasyon alanı, istasyon mahallesi, Gürcükapı, Mahallebaşı ve Gölbaşı ticari merkezleri, Taş Mağazalar Caddesi, kale surlarının yola dönüşümü, ring sistemi, aks yolları, çevre transit yolları ve idari bölgedir. Cumhuriyet ideolojisinin mekân kurgusu plan yoluyla oluşturulmaya çalışılmıştır. Ancak planın uygulanamayan yönleri (merkezi park, kenti çevreleyen yeşil sistem, mahalle bahçeleri ve kültür merkezleri, sanatkâr atölyeleri, sanayi alanı, çocuk oyun alanları ve spor alanları ile farklı nitelikteki konut bölgeleri) Erzurum için arzu edilen çevrenin ve modernleşmenin yaratılamadığını göstermektedir.

Published: October 2023

Bu çalışma, İstanbul’da yaşayan 65 yaş ve üzerindeki nüfusun COVID-19 pandemisine karşı toplumsal dayanıklılık kaynaklarını ve bu grubun pandemi gibi bir toplumsal kriz ile baş etme mekanizmalarını irdelemektedir. Veri setinin elde edildiği saha çalışması nicel ve nitel olarak karma yöntem ile uygulanmıştır. Nicel veri, İstanbul’un farklı ilçelerinde farklı gelir gruplarının yoğunlaştığı mahallelerde 65 yaş ve üzerindeki kadın ve erkeklerden oluşan 502 katılımcıya 95 sorudan oluşan tam yapılandırılmış soru kâğıdı ile elde edilmiştir. Araştırmanın nitel verisi, tam yapılandırılmış soru kağıdının uygulandığı kişiler arasındaki 50 kişiyle yapılan mülakatlara dayanmaktadır. Bu makalenin amacı doğrultusunda araştırmanın toplumsal dayanıklılık ve baş etme mekanizmalarını içeren bulgularına odaklanılmıştır. Bu bağlamda, 65 yaş ve üzerindeki nüfus için dayanıklılık kaynakları arasında temel olarak aile ilişkileri, yerel ve toplumsal aktörler ve bu kuşağın sahip olduğu sosyal güvence ve ekonomik birikimlerin yer aldığı görülmüştür. Özellikle kamusal ve kurumsal desteklerin zayıf olduğu pandemi sürecinde, yaşlı nüfusun temel ihtiyaçlarını karşılamasında ve pandemide büyük sosyal yıkımlar yaşamamasında bu mekanizma ve aktörlerin kritik düzeyde etkili olduğu anlaşılmaktadır.
Guidelines for quantifying leaf chlorophyll content via non-destructive spectrometry
Authors: Chiarenza Giancarlo Maria , Slavich Eve , Moles Angela T
Published: October 2023

Premise: Leaf chlorophyll is a fundamental bioindicator used in several fields. However, we lack clear guidelines for optimizing sampling efforts and produce comparable studies.Methods: We estimated chlorophyll for ten plant species content using spectrometry. We stored half of the leaves at 4°C and half at room temperature to assess the role of storage in chlorophyll degradation rate.Results: Refrigerated mature leaves maintain chlorophyll content within 5% of the original value for ~1.5 d, while unrefrigerated mature leaves need to be measured within 4 h. When refrigerated, expanding leaves remained within 5% of their original chlorophyll content for at least 5 d, but we suggest analysing them within 3 d. In mature leaves, 73% of the variation in chlorophyll content lies at the species level, 15% between individuals, and variation within leaves is negligible (< 1%). Measuring one mature leaf each from eight individuals is enough to provide a species chlorophyll estimate within 5% of the true value at least 80% of the time.Discussion: We advise researchers to prioritise sampling more individuals rather than repeating measures within leaves or individuals. Our findings will help researchers to optimise their time and research efforts, and to obtain more robust ecological data.
Introspective access to value-based multi-attribute choice processes

People routinely choose between options varying on multiple attributes – homes to rent, movies to watch, and so on. How much awareness do people have of the mental processes underlying their choices? Here, we develop a method to quantify awareness of value-based multi-attribute choice processes that accounts for diverse choice strategies. Across five studies, participants made choices and then reported how they believed they made them. We used computational modeling to identify the process revealed in their choices, and compared it to their self-reports to quantify individuals’ accuracy about their choice process. While we observed substantial variation in accuracy, participants were often highly accurate about their choice process – more accurate than predicted by a sample of decision scientists – and more accurate than informed third-party observers, suggesting evidence for introspection. These results challenge notions that we are “strangers to ourselves” and instead suggest that people often know how they made value-based choices.
Testing the convergent validity, domain generality, and temporal stability of selected measures of people’s tendency to explore.

Given the ubiquity of exploration in everyday life, researchers from many disciplines have developed methods to measure exploratory behaviour. There are therefore many ways to quantify and measure exploration. However, it remains unclear whether the different measures (i) have convergent validity relative to one another, (ii) capture a domain general tendency, and (iii) capture a tendency that is stable across time. In a sample of 678 participants, we found very little evidence of convergent validity for the behavioural measures (Hypothesis 1); most of the behavioural measures lacked sufficient convergent validity with one another or with the self-reports. In psychometric modelling analyses, we could not identify a good fitting model with an assumed general tendency to explore (Hypothesis 2); the best fitting model suggested that the different behavioural measures capture behaviours that are specific to the tasks. In a subsample of 254 participants who completed the study a second time, we found that the measures had stability across an 1-month timespan (Hypothesis 3). Therefore, although there were stable individual differences in how people approached each task across time, there was no generalizability across tasks, and drawing broad conclusions about exploratory behaviour from studies using these tasks may be problematic.
