CEO outside Board Service and Managerial Short-Termism
Authors: Asante-Appiah Bright , Kim Jae B. , Koo KwangJoo 
Published: October 2024

SYNOPSIS
We hypothesize that CEOs with outside board service are less likely to engage in short-term-oriented activities because external directorships can enhance their capabilities, relieve job-related concerns, and have a signaling impact in the CEO labor market. Consistent with our prediction, we find that CEOs’ outside directorships have a negative relation with short-term-oriented behaviors. The negative association is restricted to two outside directorships, particularly for a subgroup of firms with strong short-term incentives, such as firms with a small decrease in earnings. The negative nonlinear relation is also found to be more pronounced for firms operating in more homogenous industries and firms with weaker corporate governance. Additionally, we document that CEO outside board service has a positive relation with long-term-oriented behaviors and long-term firm performance. This study suggests that outside board service up to two positions can reduce managers’ short-termism and promote long-termism, improving the long-term performance of their employer firms.

Task-Specific Experience, Tacit Knowledge, and Compensation Contracts
Authors: Cardinaels Eddy , Dierynck Bart , Yin Huaxiang , Beckers Nathalie 
Published: October 2024

ABSTRACT
This study experimentally examines whether managers’ task-specific experience influences their reliance on performance-based contracts to motivate employees to perform cognitively stimulating tasks. Building on experiential learning theory, we predict managers who acquire task-specific experience by doing the employee’s task possess tacit knowledge about the task’s cognitive stimulation and associated intrinsic motivation. To motivate their employees, these managers will prefer a fixed-wage contract, which relies on intrinsic motivation, over a performance-based contract. Our results support these predictions. Managers who perform the employee’s task are less likely to choose the performance-based contract than managers who only read a description of the task. Additional analysis shows managers’ perception of the task’s cognitive stimulation and employees’ intrinsic motivation to complete the task explain the contract choice. We run three additional experiments to better understand the impact of task-specific experience on contract choice. Our study underscores the importance of task-specific experience for compensation contract design.

Penelitian ini membahas implementasi sistem deteksi kegagalan pada transformator menggunakan analisis gas terlarut Dissolved Gas Analysis (DGA) dengan menerapkan metode Logistic Regression. Tujuan penelitian ini adalah membuat sistem yang dapat meningkatkan keandalan transformator, mengurangi risiko gangguan listrik, dan memberikan kontribusi pada praktik industri berupa penerapan metode yang efisien dalam pemeliharaan transformator daya. Penggunaan data DGA dari transformator yang mengalami berbagai tingkat kerusakan sebagai sampel pelatihan dan pengujian menunjukkan bahwa Logistic Regression memberikan performa yang sangat baik dengan tingkat akurasi, presisi, F1-Score, dan recall berturut-turut sebesar 97%, 97%, 97%, dan 97%. Hasil ini mencerminkan kemampuan metode ini dalam mengklasifikasi hasil positif dan negatif. Sementara itu key gas memiliki akurasi, presisi, dan F1-Score yang rendah (42%, 17%, dan 24%), Recall 42% yang sedikit lebih tinggi menunjukkan kemampuan metode ini untuk mendeteksi sejumlah besar positif aktual, tetapi dengan tingkat kesalahan yang lebih tinggi. Penemuan ini berpotensi meningkatkan keandalan sistem tenaga listrik melalui pemeliharaan dini dan deteksi tepat waktu terhadap potensi masalah pada transformator.

Abstract

OBJECTIVE
The investigators' hypothesis is that Jack Russell Terriers (JRTs), Miniature Pinschers (MPs), and Brussels Griffons (BGs) without underlying cardiac disease have breed-specific vertebral heart size (VHS) reference intervals.

METHODS
The electronic medical records of IDEXX Telemedicine Consultants were searched for JRTs, MPs, and BGs undergoing radiography from January 1, 2023, through June 30, 2023. The study range was expanded to January 1 2022, through June 30, 2023, for BGs only to improve case volume. Dogs were included if they had 2- or 3-view thoracic radiographs performed and no evidence of cardiopulmonary or systemic disease. The VHS and vertebral left atrial size (VLAS) measurements were performed by the same board-certified cardiologist for all images.

RESULTS
During the study period, a total of 991 JRTs, 750 MPs, and 399 BGs were identified. Of these, 689 JRTs, 512 MPs, and 267 BGs were excluded, leaving 302 JRTs, 238 MPs, and 132 BGs available for analysis. The reference intervals for JRTs were 9.7v to 11.8v for VHS and 1.8v to 2.6v for VLAS. The reference intervals for MPs were 9.6v to 12.2v for VHS and 1.7v to 2.4v for VLAS. The reference intervals for BGs were 9.3v to 11.9v for VHS and 1.7v to 2.4v for VLAS.

CONCLUSIONS
Jack Russell Terriers, MPs, and BGs have breed-specific VHS and VLAS reference intervals.

CLINICAL RELEVANCE
Clinicians should be aware of these results to accurately diagnose cardiac disease in these 3 breeds.
Temporary palatopexy procedure for brachycephalic obstructive airway crisis in dogs
Authors: Sun Jessica 
Published: October 2024

Abstract

OBJECTIVE
To provide a video tutorial on how to perform a temporary palatopexy in an anesthetized brachycephalic dog.

ANIMALS
Brachycephalic dogs.

METHODS
To perform a temporary palatopexy, needle drivers, forceps, intubation equipment, and absorbable suture material are needed. In an anesthetized and ideally intubated patient, buried sutures are placed, tacking the free edge of the soft palate to the junction of the hard and soft palate.

RESULTS
Temporary palatopexy pulls the soft palate out of the airway to improve airflow and manage brachycephalic upper airway crises.

CLINICAL RELEVANCE
Temporary palatopexy can be used for brachycephalic obstructive airway crises in an attempt to avoid prolonged intubation, temporary tracheostomy, emergent palatoplasty, euthanasia, or death. This is not intended to replace permanent palatoplasty but to allow time for stabilization/transfer or delay palatoplasty due to the higher complication rate of emergent palatoplasty.

Abstract

OBJECTIVE
To evaluate nonsurgical management outcomes of cleft palate (CP) in dogs and identify any association between cleft size, prevalence of clinical signs, and quality of life (QoL).

METHODS
65 dogs treated conservatively for CP from January 2006 through December 2023 were retrospectively identified. Diet, activity, medical history, and QoL were recorded for dogs that survived to the transition to solid food. Results were compared to those from 24 control dogs. Measurements of cleft area, width, and percentage of the hard palate occupied by the cleft were made with the use of calibrated photographs. Clefts were divided into 3 types: wide throughout, wide rostrally, and slit throughout.

RESULTS
Sneezing was the most frequent clinical sign (43 of 65 over the past month, 34 of 65 when most affected). There was a greater frequency of material lodging in the cleft in the wide-throughout clefts (13 of 16 dogs) compared to the slit-throughout clefts (7 of 19 dogs). Veterinary removal of material was required in 10 of 68 episodes (7 of 31 dogs). There was no correlation between cleft size and prevalence of clinical signs or QoL. Sixty-three percent of dogs had a perfect QoL on a weighted scale, while 83.3% had a perfect score on a visual analog scale. Sixty-four of 65 owners would adopt another dog with a CP.

CONCLUSIONS
Measures of QoL were favorable among dogs treated conservatively for CP.

CLINICAL RELEVANCE
Conservative management appears to be a viable option for treatment of CPs in some dogs.

Infrastructure development, particularly the Semarang-Demak Toll Road Project, poses serious challenges concerning the procurement of land for public use, especially in the context of unique land characteristics such as degraded land. This study examines legal aspects related to land acquisition within the framework of Indonesia's national agrarian law, including the state's role in ensuring justice and protection of land rights for the community. The issue is analyzed from the perspective of relevant regulations and legal responses to degraded land conditions. The importance of ensuring equal land rights for all citizens is highlighted, in line with the principles of national agrarian law. However, in addressing infrastructure development challenges, particularly concerning land with special characteristics, as seen in the Semarang-Demak Toll Road Project, adaptive regulations are needed. However, in facing the challenges of infrastructure development, especially concerning land with such specific characteristics, adaptive regulations are required. This is reflected in the implementation of special regulations set by the Government, particularly regulating the issue of land acquisition in the context of development for public interest. Research encompasses the differences between general land acquisition mechanisms and mechanisms for addressing social and community impacts on land conditions owned by the community at the project site. Resolving the issues in the project in question relies not only on legal regulations but also requires good collaboration and coordination between policymakers and the community.

Published: October 2024

An investigation was carried out to explore the effect of salinity on the growth and flesh quality of African catfish (Clarias gariepinus), a significant species in global aquaculture. Fifty juvenile catfish of weight 24.25±0.4g were collected from the Chenab River in Pakistan and acclimatized in controlled aquaculture conditions at different salinity levels NaCl (T1; 0, T2; 2, T3; 4; T4; 6, and T5; 8 ppt) over 60 days. Growth performance indicators, including final weights, weight gain, growth rate, and feed conversion ratio (FCR), were measured. The statistical result indicated that the fish in lower salinity environments (0-2 ppt) exhibited significant (p < 0.05) final weights, weight gain, and growth rates, with performance declining significantly as salinity increased. The best FCR 1.2±0.01 was indicated at 0 ppt, while the highest salinity (8 ppt) was revealed in the FCR 1.7±0.04. Proximate composition analysis indicated that crude protein and moisture content elevated with salinity while crude fat and ash content decreased. These results suggest that C. gariepinus thrives in slightly brackish conditions, with optimal growth at low salinity levels. However, higher salinities adversely impact physiological health and growth performance.

Проблема совершенствования машиностроительных производств приобретает первостепенное значение. Требуемая точность высокоточных изделий достигается при традиционных методах изготовления усложнением технологического оборудования и использованием информационных и измерительных технологий. В настоящее время функциональная точность высокоточных изделий превзошла точность обрабатывающего и сборочного оборудований почти на порядок. Это привело к возникновению проблемы достижения заданного качества и точности высокоточных изделий при их изготовлении. На сегодняшний день наблюдаются разрозненные решения отдельных задач этой проблемы, отсутствует наиболее приближенная к реальным требованиям концепция системы в целом. В данной статье формируется структура комплекса проектных процедур, который основывается на установлении связи между технологической подготовкой механообрабатывающего и сборочного производств. Также в статье рассматриваются математическая модель представления и анализа деталей и сборок (исходными данными являются полученные графы сопряжений сборочной единицы и графы размеров) и подход для автоматизации расчета технологических размерных цепей (исходными данными являются граф технологического процесса и размерные цепи).
The problem of improving machine-building production is of paramount importance. The required precision is achieved with the traditional methods of manufacturing. They are: the complication of the processing equipment and the applying of the information technologies and measurement technologies. At present, the functional precision of the high-precision products (the devices and the machines) has surpassed the precision of the machining equipment and the assembly equipment almost by a decade. This leads to the problem of the achieving of the specified quality and accuracy of the high-precision products during their manufacture. Now there are just the segmental solutions for some specific tasks of these issues, such as the upgrading of the quality and the precision of the production, the reduction of the material costs, the adoption of the resource-saving technologies and so on. But the unifying vision of the system meeting the real requirements does not exist. In the present paper the discipline of the holistic approach (complex of design procedures) which provide the effectiveness of the realization of the assembly operations is considered. The effective realization of the assembly operations is based on the links between the process design of the manufacturing of the high-precision products and the process design of the assembly production of the high-precision products. Moreover, mathematical models and approaches of realization of the complex are considered in this paper.

Изложены результаты экспериментальных исследований влияния ультразвука на обрабатываемость армированного углеродными волокнами углепластика с квазиизотропной структурой. Установлено, что при ультразвуковом микрорезании композиционных материалов по кромках царапины практически не наблюдается разориентированных вытянутых из структуры армирующих волокон. При сверлении отверстий малого диаметра в образцах из армированного углеродными волокнами композиционного материала с сообщением инструменту ультразвуковых колебаний малой амплитуды на выходе инструмента отсутствует валик разориентированных волокон, кромки отверстия практически чистые, что позволяет исключить слесарную операцию зачистки и снизить трудоемкость процесса. Полученные результаты позволяют сделать вывод об эффективности применения ультразвуковой обработки для улучшения эксплуатационных характеристик и качества размерной обработки изделий из композиционных конструкционных материалов.

В статье представлена феноменологическая модель кавитационной интенсификации химических реакций в высокоинтенсивном ультразвуковом поле. В основе предложенной модели лежит статистический подход, который заключается в оценке константы скорости химической реакции, усредненной по объему. Усреднение проводится по объему, который намного больше, чем объем кавитационного пузырька, в котором микроскопическое значение постоянной зависит от ударного волнового давления при коллапсе кавитационных пузырьков. Константа скорости химической реакции зависит от давления и рассчитывается с использованием распределения скоростей молекул Максвелла и вероятности события, что энергия молекулы больше энергии активации для данной реакции. Численный анализ модели показал, что ультразвуковое воздействие повышает эффективность химических реакций в 1,5 раза.
The paper is devoted to proposed phenomenological model of cavitation intensification of chemical reactions in high-intensity ultrasonic field. The model is based statistical approach which is evaluation of volume-averaged chemical reaction rate constant. Averaging is performed over volume that is much more than cavitation bubble volume in which the microscopic value of constant depends on shock wave pressure at cavitation bubbles collapse. The chemical reaction constant dependency on pressure is calculated by using Maxwell distribution of molecules velocities and probability of event that the molecule energy is more than activation energy for given reaction. The numerical analysis of model shown that ultrasonic influence increase of chemical reaction efficiency up to 1.5 times.

Рассмотрено влияние процесса формообразования в разбуренном реголите Луны на движение ультразвукового пенетрационного устройства (ПУ). Сформулированы условия преодоления заклинивания ПУ с учетом изменения свойств реголита с глубиной, в том числе присутствия водяного льда. Рассмотрены требования к ПУ при реализации двух режимов его работы на Луне: определения содержания воды в реголите в зависимости от глубины бурения и взятия образцов грунта для определения содержания летучих компонентов.
The influence of the shaping process in the drilled regolith of the Moon on the motion of an ultrasonic penetration device (PU) is considered. The conditions for overcoming the jamming of PU are formulated taking into account the changes in the properties of regolith with depth, including the presence of water ice. The requirements for the PU are considered when implementing two modes of its operation on the Moon: determining the water content in the regolith depending on the depth of drilling and taking soil samples to determine the content of volatile components.
