Gender dysphoria is linked to various psychosocial challenges in adolescence, underscoring the need to identify and support youth experiencing gender-related distress. Although gender identity exists on a spectrum beyond the binary, no validated tool currently exists in Turkey that uses inclusive, gender-neutral language to assess it in adolescents.
Aims
This study aimed to evaluate the psychometric properties of the Turkish adaptation of the Utrecht Gender Dysphoria Scale–Gender Spectrum (UGDS-GS) among clinical- and community-based adolescents.
Method
A total of 240 participants aged 12–23 years were included. The validity of UGDS-GS was assessed through content validity and confirmatory factor analysis. Reliability was measured using Cronbachʼs alpha and test–retest intraclass correlation coefficient (ICC). A sociodemographic data form, UGDS, UGDS-GS, Rosenberg Self-Esteem Scale (RSES) and Youth Self-Report (YSR) were utilised.
Results
Findings demonstrated strong content validity, with a content validity Index of 0.69, and robust construct validity, indicated by a comparative fit index of 0.993 and a root-mean-square error of approximation of 0.071 following the exclusion of three items. UGDS-GS effectively differentiated scores across demographic groups, showing significant variances based on assigned gender and age. The scale also exhibited excellent criterion validity, evidenced by an area under the curve of 0.947 in receiver operating characteristic analysis, with high sensitivity (80%) and specificity (95.9%) at an optimal cut-off value of 42.50. With a Cronbachʼs alpha of 0.935, UGDS-GS demonstrated strong internal consistency and substantial test–receiver operating characteristic retest reliability (ICC 0.884), alongside notable but weak correlations with several RSES subscales and low to moderate correlations with YSR scores.
Conclusions
These results affirm that tUGDS-GS is valuable and reliable in assessing gender dysphoria in Turkish adolescents. Further research is warranted to improve applicability in diverse contexts and populations.
Combining key elements of classical and constructivist approaches to representation, this article suggests a novel reconceptualisation of political representation. Developed through participatory agency research with people in socio-economically difficult situations and anchored in people’s lived experiences and sense-making processes, the representative relationship is redefined as a pragmatic and solution-oriented partnership between representatives and the represented. Expanding the classical Pitkinian model, it enables representatives to be better informed about how to address peoples’ concerns. In doing so, it advances the notion of dynamic political representation, where the represented are not passive principals but active partners in decision-making. While we uphold the classical principle of acting in the interests of the represented, we reconceptualise these interests as dynamic and continuously evolving – a perspective consistent with constructivist thought. This research aligns with scholarly calls to rethink representation and revise the roles of the representatives and the represented, fostering meaningful and effective engagement. Our empirical findings highlight the urgency of reform for people in socio-economically difficult situations and underscores the broader relevance of these insights, in a context of increasing legitimacy deficits and rising discontent with current modes of representation in contemporary democracies.
Harry Frankfurt claims that the object of love can be ‘almost anything’. Using Frankfurt’s conception of love, I argue that I could still love my girlfriend even if she were a worm. This conclusion can be motivated by three philosophical considerations: conceivability, anti-essentialism and the scope of what is volitionally possible. This apologia provides an introductory sketch of how the object of one’s love can change radically over time. A cautionary note: it does not provide sufficient resources for boyfriends everywhere to escape the force of this question.
The rise of remote work has reshaped organizational dynamics, necessitating a deeper understanding of its implications for leadership, employee motivation, and performance. This longitudinal study examined direct and indirect effects (via leadership behaviors) of remote work intensity on employee motivation and performance. Using three waves of survey data from 512 Norwegian employees, results indicate that higher remote work intensity positively predicted perceived need-supportive leadership and negatively predicted perceived controlling and laissez-faire leadership. Need-supportive leadership positively predicted intrinsic motivation, which in turn predicted adaptability and proactivity, whereas controlling leadership positively predicted extrinsic regulation and amotivation. Amotivation negatively predicted proficiency but was a positive predictor of proactivity. Laissez-faire leadership also positively predicted proactivity, suggesting that reduced managerial oversight may encourage initiative in certain remote work contexts. These results offer valuable insights for organizations navigating the future of work, highlighting the need for leadership strategies that enhance intrinsic motivation and adaptability in remote work settings.
Particle motions under nonlinear gravity waves at the free surface of a two-dimensional incompressible and inviscid fluid are considered. The Euler equations are solved numerically using a high-order spectral method based on a Hamiltonian formulation of the water-wave problem. Extending this approach, a numerical procedure is devised to estimate the fluid velocity at any point in the fluid domain given surface data. The reconstructed velocity field is integrated to obtain particle trajectories for which an analysis is provided, focusing on two questions. The first question is the influence of a wave setup or setdown as is typical in coastal conditions. It is shown that such local changes in the mean water level can lead to qualitatively different pictures of the internal flow dynamics. These changes are also associated with rather strong background currents which dominate the particle transport and, in particular, can be an order of magnitude larger than the well-known Stokes drift. The second question is whether these particle dynamics can be described with a simplified wave model. The Korteweg–de Vries equation is found to provide a good approximation for small- to moderate-amplitude waves on shallow and intermediate water depth. Despite discrepancies in severe cases, it is able to reproduce characteristic features of particle paths for a wave setup or setdown.
Whether an issue estoppel arises over foreign decisions on the governing law of the claim has not been directly considered by an English court, but decisions in other jurisdictions show that this question is increasingly being raised in litigation. Is there identity of issue if the two courts apply different choice of law rules? The answer turns on whether a broad or narrow framing of the issue is adopted. It is suggested that, absent an issue which is subject to forum international public policy, forum overriding mandatory rules or which is one that the forum court retains the prerogative to determine for itself, a broad framing ought to be adopted. Thus, in principle, an issue estoppel should arise over the identity of the governing law of the claim. However, issue estoppel should not operate where the choice of law category involved is underpinned by public policy considerations. The consideration of the specific issue of the governing law of the claim also feeds into broader questions on the applicability of issue estoppel whenever the two courts would apply different laws or frameworks to decide the issue. In general, whether a plea of issue estoppel ought to succeed depends on balancing the principles underlying res judicata against the considerations arising in each specific context.
In Reciprocal Freedom, Weinrib offers a neat and powerful explanation of the relationship between private law, corrective justice, public law, and distributive justice. In the Kantian view, private law and corrective justice are conceptually prior to public law and distributive justice. The primary function of public law is to publicly determine and enforce private rights. Institutions of distributive justice are required to legitimize a system of private rights that creates the possibility of subordination. In this comment, I argue that Reciprocal Freedom is a justification for what I will call ‘orthodox private law’ that, because it neglects the place of distributive justice within private law, fails to secure genuine independence for all persons.
In the preceding article, Terence Moore argues that the meanings of words are private and hidden, and that using language meaningfully involves private processes that are ‘little understood’. In this response I explain why Wittgenstein would, I believe, reject this way of thinking about meaning.
This article traces the figure of the lūṭī in the writings of Ibn Qayyim al-Jawziyyah (d. 1350) and Ibn Kathīr (d. 1373). These two fourteenth-century scholars adopted a harsh and uncompromising view of the lūṭī as a sexual actor, repeatedly depicting the horrific afterlife punishments awaiting him in Hell. As part of their hyperbolic and extreme depiction of the lūṭī as a damned sexual figure, they imagine him through his communal relationship to his forebears, both among the Qur’anic People of Lūṭ and those like him in his present day. They thereby construct a sexual community of sorts, framing the lūṭī through a parodic repurposing of a strikingly Islamic idiom of belonging and community-building. In doing so, I argue, these texts open up broad possibilities for us to rethink how medieval authors theorised what we might call ‘sexual identity’ and understood sex to construct ways of being in the world around them.
The functional outcome of patients with psychotic disturbances is associated with several overlapping premorbid, societal, neuropsychological, and clinical factors. Extracting the factors associated with functional outcomes is important for designing effective mental health interventions.
Methods
In a naturalistic prospective European multicentre study, we analysed the effects of sociodemographic, preadmission, admission, and postadmission precursors on functional outcomes in 296 patients with recent-onset psychosis (ROP) and 262 patients at clinically high risk of psychosis (CHR-P). Functioning was assessed with the Global Assessment of Functioning—symptoms and deficits version—at baseline and at the 9- and 18-month follow-ups.
Results
In the overall sample, male sex, childhood adversities, poor sociability, scholastic problems, neurocognitive deficits, and greater severity of baseline and follow-up symptoms were associated with poor functional outcomes. In contrast, a favourable work/educational situation and preadmission treatment for nonpsychotic disorders were associated with better functional outcomes. Among ROP patients, neurocognitive deficits and the severity of baseline and follow-up affective and psychotic symptoms were strongly associated with functional outcomes. Among CHR-P patients, premorbid sociability, previous treatment for affective disorders, and follow-up affective symptoms played more significant roles.
Conclusions
To improve functioning in patients in the early stages of psychosis, several factors should be considered, such as sex, childhood adversities, psychosocial development, baseline neurocognitive deficits, work/educational situation, clinical presentations, and follow-up symptoms. Personalized and integrated treatment and rehabilitation measures should be actively continued beyond the first admission period, with a particular focus on addressing both baseline and follow-up affective disturbances.
Bounding energetic growth of gyrokinetic instabilities is a complementary approach to linear instability analyses involving normal eigenmodes. Previous work has focused on upper bounds which are valid linearly and nonlinearly. However, if an upper bound on linear instability growth is desired, these nonlinearly valid bounds may be a poor predictor of the growth of the most unstable eigenmode. This is most evident for the simplest of instabilities: the ion-temperature-gradient (ITG) mode in a slab geometry. In this work, we derive energetic upper bounds specifically for linear instability growth, focusing on the slab ITG. We show that there is no fundamental limitation on how tightly linear growth can be bounded by an energetic norm, with the tightest possible bound being given by a special energy comprising projection coefficients of the linear eigenmode basis. Additionally, we consider ‘constrained optimal modes’ that maximise energy growth subject to constraints that are also obeyed by the linear eigenmodes. This yields computationally efficient upper bounds that closely resemble the linear growth rate, capturing effects connected to the real frequency of instabilities, which have been absent in the energetic bounds considered thus far.
Many cities have lost significant old buildings in a push for redevelopment. While there is a case for preservation, there can be, and often are, strong arguments for redevelopment. This article takes a philosophical look at the arguments found on both sides of the debate.
This paper extends our previous study of the gyro-emission by energetic electrons in the magnetospheres of rapidly rotating, magnetic massive stars, through a quantitative analysis of the role of cooling by Coulomb collisions with thermal electrons from stellar wind material trapped within the centrifugal magnetosphere (CM). For the standard, simple CM model of a dipole field with aligned magnetic and rotational axes, we show that both gyro-cooling along magnetic loops and Coulomb cooling in the CM layer have nearly the same dependence on the magnitude and radial variation of magnetic field, implying then that their ratio is a global parameter that is largely independent of the field. Analytic analysis shows that, for electrons introduced near the CM layer around a magnetic loop apex, collisional cooling is more important for electrons with high pitch angle, while more field-aligned electrons cool by gyro-emission near their mirror point close to the loop base. Numerical models that assume a gyrotropic initial deposition with a gaussian distribution in both radius and loop co-latitude show the residual gyro-emission is generally strongest near the loop base, with highly relativistic electrons suffering much lower collisional losses than lower-energy electrons that are only mildly relativistic. Even for cases in which the energy deposition is narrowly concentrated near the loop apex, the computed residual emission shows a surprisingly broad distribution with magnetic field strength, suggesting that associated observed radio spectra should generally have a similarly broad frequency distribution. Finally, we briefly discuss the potential applicability of this formalism to magnetic ultracool dwarfs (UCDs), for which Very Long Baseline Interferometry (VLBI) observations indicate incoherent radio emission to be concentrated around the magnetic equator, in contrast to our predictions here for magnetic hot stars. We suggest that this difference could be attributed to UCDs having either a lower ambient density of thermal electrons, or more highly relativistic non-thermal electrons, both of which would reduce the relative importance of the collisional cooling explored here.
Food preservation, including salting and barreling meat, has played a significant role in human history; however, it remains challenging to identify cases of salting in the archaeological record. Most studies have relied on limited datasets and focus on body-part profiles observed in faunal assemblages. Known and suspected cases of barreled meat and on-site butchery, drawn from six shipwrecks and seven fur trade posts, provide a means of identifying body-part profiles for salted pork and beef. Modeled body-part profiles based on these data reveal differences in expected body-part frequency between salted and locally butchered beef, although the patterning is less obvious for pork. Comparing these models against 26 military forts reveals that, despite the prominence of salted beef and pork in historic records, many forts exhibit patterns consistent with on-site butchery of live animals.
Considerable evidence survives of the cooking and eating of kebabs as a major form of meat consumption in early China. Not only are there numerous artistic depictions in both painting and low-relief stone sculpture of this practice, but there are also some very early excavated skewers, grills, and indeed preserved meat kebabs, not to mention references in contemporary literature, and this evidence significantly predates any documentation of kebabs in the Middle East. However, in spite of this wealth of documentation, this tradition has gone largely unexplored, partly due to scholars failing to understand the relevant terminology and partly due to an unjustified belief that all kebab cooking must derive from the Middle East. This article explores the indigenous ancient Chinese tradition of kebab cooking, focused on grilling and roasting of smaller (luan) or larger (zi) pieces of meat seasoned with soybean pastes and sauces, which developed independently of other similar culinary practices elsewhere. This analysis is focused on literary evidence of the Chinese kebab, with particular reference to the contents of a recently discovered very early cookbook, dating to the Han Dynasty, excavated from the tomb of Wu Yang, first marquis of Yuanling, who died in 162 BCE.
Five unknown Holocene flank eruptions from the Masaya caldera are reported here. These eruptions comprise basaltic lava flows emplaced in Masaya’s northern rift zone along the Cofradía fault zone, east of Managua City. The lava flows were defined as Mosintepe, Portillo, Gorgonia, Campuzano, and Martha units. Paleosol samples were collected below each lava flow, and radiocarbon AMS analyses were performed, yielding ages of 2250 ± 30, 1610 ± 30, 1600 ± 30, 1140 ± 30, and 790 ± 30 yrs BP, respectively. Calibrated age intervals are 285–229 cal BC for Mosintepe, 496–534 cal AD for Portillo, 496–535 cal AD for Gorgonia, 914–976 cal AD for Campuzano, and 1226–1268 cal AD for Martha; all stratigraphically consistent. These eruptions emitted magma bulk volumes between 0.02 and 0.51 km3, reaching up to 8 km from their eruptive vent and 13 km from Masaya’s polygenetic system summit crater. Their mineral paragenesis, and major and trace element geochemical fingerprint reveals a common volcanic provenance from the Masaya caldera due to lateral magma draining. This study demonstrates that basaltic lava flow flank eruptions are common in the Masaya caldera along its northern volcanic rift zone. Therefore, this information should be considered in future hazard and risk assessments.
Thérèse Humbert was a lowly French peasant until she saved the life of an American millionaire who left her a vast inheritance, but after twenty years of litigation over said inheritance, a massive web of deception unraveled. The millionaire had never existed, his “nephews” were actually Humbert’s brothers, and Humbert herself had swindled Europe’s moneyed men and working-class laborers out of millions of francs. Overnight, Humbert became a celebrity in the American press, even after she was convicted and imprisoned for fraud. The French swindler’s onslaught of coverage in American newspapers shaped Gilded Age anxieties about money, credit, and the place of women in an ever-changing world. Gender ideologies concerning women’s place in the economy and turn-of-the-century financial instability made the Humbert swindle irresistible to the American press, who saw the story as an opportunity to moralize about women and finance. The sheer scale of Humbert’s fraud and its American coverage make the story remarkable today as an astonishing episode in the Gilded Age and Progressive Era, especially among cultural historians and those interested in the New History of Capitalism.
