The Bosniak and Albanian minorities in postcommunist Montenegro have supported and been represented by mainstream Montenegrin parties more than by their ethnic parties. This stands in striking contrast to the situation in neighboring Serbia and North Macedonia where the Bosniak and Albanian minorities vote almost exclusively for their ethnic parties. The Montenegrin case stands out as deviant also when one considers a number of extant explanations, all of which would predict a different outcome. Montenegrin Bosniaks and Albanians constitute two native, sizeable and geographically concentrated minority groups inhabiting a country with an institutional framework and several special electoral arrangements favoring minority parties. Drawing on original data on Bosniak and Albanian legislators elected across 12 parliamentary elections in Montenegro (1990–2023), municipality and country-level parliamentary election results and 12 semi-structured elite interviews, I argue that what explains the deviance in the Montenegrin case is the peculiar nature of Montenegrin identity, specifically the fact that it does not pit the majority against minority, but rather it pits the Montenegrin and Serbian components of the Orthodox majority against each other and in such a context the non-Orthodox minorities become critical political allies of the Montenegrin bloc against the Serbian one.

Elected officials can often successfully increase voter support in their district by “bringing home the bacon,” yet theory suggests that the electoral effects of such efforts may depend on the legislator’s gender and whether the legislator delivered benefits in a stereotypically feminine (e.g., healthcare) or masculine (e.g., agriculture) issue area. Using both observational and experimental data in the United States, we find weak, limited evidence that issue area conditions the electoral impact of credit claiming for legislators of either gender. In addition, we show that men and women are rewarded comparably when they secure benefits for their district, regardless of issue area. Our findings suggest that women legislators — typically more effective than men at securing these benefits — can use distributive politics and credit claiming as an effective electoral strategy without concern that issue-based gender biases in the electorate will get in the way.

Following the COVID-19 pandemic, assessments by video link became a standard and acceptable form of medico-legal evaluation. The various challenges to achieving an accurate and robust medico-legal assessment via a remote platform are explored in this clinical reflection. It is concluded that any limitations to a remotely undertaken assessment must be highlighted to the court and an in-person assessment considered as a reasonable alternative in some cases.

The wheeled-legged robot combines the advantages of wheeled and legged robots, making it easier to assist people in completing repetitive and time-consuming tasks in their daily lives. This paper presents a study on the kinematic and dynamic modeling, as well as the controller design, of a wheeled biped robot with a parallel five-bar linkage mechanism as its leg module. During the motion of the robot, the robot relies on the tilt angle of the inverted pendulum, and this angle often results in the tilting of the chassis of the robot, presenting challenges for the installation of upper-body payloads and sensor systems. The controller proposed in this paper, which is developed by decoupling the primary motions of the robot and designing a multi-objective, multilevel controller, addresses this issue. This controller employs the pendulum pitch angle of the equivalent inverted pendulum model as the control variable and compensates for the chassis tilt angle (CTA). This control method can effectively reduce the CTA of such robots and eliminate the need for additional counterweights. It also provides a more spacious structural design for accommodating upper-body devices. The effectiveness of this control framework is verified through variable height control, walking on flat ground, and carrying loads over rough terrain and slopes.

Voice production can be influenced by interindividual variations related to genetic, physiological, behavioral, and several environmental factors. Here we examined the effect of zygosity on speaking fundamental frequency (F0) statistical descriptors. Our aims were: (1) to determine whether the genetic similarity between monozygotic (MZ) and dizygotic (DZ) twins affects F0 characteristics, and (2) to quantify the contribution of genetic factors to these characteristics. The study involved 79 same-sex twin pairs of Brazilian Portuguese speakers, comprising 65 MZ and 14 DZ twins, aged 18 to 66 years (31.7 ± 11.6 years), with 21 male and 58 female pairs. Participants were recorded while uttering a greeting phrase and the Brazilian Portuguese version of the ‘Happy Birthday to You’ song. Speech segments were analyzed using Praat free software, and F0 measures were automatically extracted in both Hertz and semitone scales. Statistical descriptors, including centrality, dispersion, and extreme values of F0 were examined, and the ACE model (i.e., total genetic effects, A; shared environmental influences, C; and nonshared environmental influences, E) was employed to estimate the additive effect;ts of monozygosity. As anticipated, we observed a zygosity effect on several F0 parameters, with more similarity between MZ twins compared to DZ twins. We discuss the genetic influences on F0 parameters and the absence of a monozygosity effect in two of them. Additionally, we briefly address potential biases associated with the selected measurement scale for statistical modeling. Finally, we explore the influence of genetic factors on F0 patterns, as well as environmental, life history and linguistic factors, particularly concerning F0 variation in speech.

Transcatheter pulmonary vein recanalisation is challenging. Herein, we described a novel technique facilitating the recanalisation of occluded three pulmonary veins in two small children. This technique enhances the catheter’s alignment and stability during the recanalisation process. Referred to as the “anchoring guide catheter” technique, it can be applied only when the ipsilateral vein is patent.
