Authors: Shinwari Waseem Khan
Published: October 2024

This masterpiece of Darren Hardy was released in 2010. The book emphasizes the significance of our daily choices in achieving our life objectives. The compound effect will assist readers in creating a strategy, altering their behaviors, gain momentum to perform better, and challenge their limitations / shortcomings. This book is a brief yet insightful manuscript that looks at the concept of reaping huge benefits from making minor but smart decisions to achieve success and live the life of your dreams. The concept of the compound effect is just like compound interest in finance, i.e., small everyday actions give huge returns over time. In this book, Darren Hardy, the founder and editorial director of SUCCESS magazine, has shared his personal life experiences as well as lessons learned from interviewing many of today's most famous achievers.

Impact of Organizational Politics on Organization Success, Job Satisfaction and Turnover Intentions with Moderating Effect of Individual Values
Authors: Iqbal Iqra
Published: October 2024

Organizational politics is an adverse factor that negatively affects organizational outcomes. Various empirical evidences have concluded organizational politics as averse phenomenon. A plethora of research has reported a positive relationship between organizational politics and turnover intentions and a negative relationship between job satisfaction and organizational success. However, according to recent meta analytical and systematic reviews, the relationship has varying degrees. For example the relationships between organizational politics to job satisfaction, turnover intentions and organizational success are inconsistent. The inconclusive nature of the relationship called attention of scholars to examine possible moderators.  Our study therefore, attempted to examine the role of individual values as moderator on the organizational politics to job satisfaction, turnover intentions and organizational success relationships. A sample of 318 employees from real estate organizations in twin cities of Islamabad and Rawalpindi was collected. Questionnaire survey was employed through convenience sampling technique. Standard measures were taken to control social desirability response and common method variance. Result showed strong positive relationship between organizational politics and turnover intentions and significant negative relationships between organizational politics to job satisfaction and organizational success. Moreover, individual values showed a moderating role on the organizational politics to turnover intentions, job satisfaction and organizational success relationships. Theoretical and practical implications are discussed based on the findings of the study.

Developing Organizational Change Capabilities using ADKAR model of Change: The Efficacy of Context Sensitive Training
Authors: Hanif Sadia
Published: October 2024

Organizational change and development are a challenge for stagnant culture of public sector Organizations in Developing Countries. Training plays a vital role in organizational change and development. However, it is not clear how training modules, methods and approaches should be designed and implemented that direct the organizational change and development towards desired outcomes. The present study considers the case of Pakistan Public Sector Organizations and studies the training dilemmas in three dimensions. Using the grounded theory approach, qualitative data collection tools were adopted to collect data from trainees, trainers, and the training organizations. The data from trainees helps to identify the learning behaviors, training methodologies and the organizational needs versus training contents. The data from trainers informed the trainers’ perceptions on learning behaviors, training methodologies and modules adopted and related constraints. Finally, the data from training organizations helps the researcher to observe the real picture through observations, and to understand the process of designing training calendars and their coordination with public sector organizations. The sample of the study completed with the saturation of emergent themes. The collected data was analyzed using Grounded theory analysis in MAXQDA. The results show that there is lack of match between organizational needs, learning behaviors and the training approaches. This mismatch leads to further controversies such as inappropriate learning behaviors, and lack of competency development. These controversies impede the organizational change and development processes. If training improves as per organizational needs and learning behaviors, this can lead to improved organizational change and development. In this regard, the study has suggested a model for organizational change through Context Sensitive training.

Detention in Greenland. Night-time correctional institutions, probation and hostels for juvenile offenders as seen by inmates and staff
Authors: Brochmann Helene
Published: October 2024

The present work is the result of a study dealing with the way in which people who have been committed to a night-time correctional institution, supervision or hostel for juvenile offenders experience their loss of freedom or their supervision and the treatment they are accorded in the system.
The objective is to establish a knowledge of how the measures applied by the Prison Service are carried out in practice. The data on which the study is based were collected in interviews with convicted persons and the staff in the institutions and the Prison Service.
The Greenlandic Penal Code is known for its so-called "offender principle", according to which it is not the intention for the sentences to punish, but to find the "measure" judged to be most suited to prevent the guilty person from engaging in further crime. The aim of rehabilitation plays an important part.
It emerges from the report that the original intentions concerning treatment and rehabilitation are not so easy to fulfil as the originators of the Criminal Code might have imagined, but at the same time a picture is also drawn of a prison system which still differs fundamentally from what is known in the rest of the world.
Orientation systems of the North Pacific Rim
Authors: Fortescue Michael
Published: October 2024

Orientation Systems of the North Pacific Rim is an extension of the author’s earlier volume Eskimo Orientation Systems (also published in the series Monographs on Greenland | Meddelelser om Grønland, Man & Society, 1988). This time it covers all the contiguous languages – and cultures – across the northern Pacific rim from Vancouver Island in Canada to Hokkaido in northern Japan, plus the adjacent Arctic coasts of Alaska and Chukotka. These form a testing ground for recent theories concerning the nature and classification of orientation systems and their shared ‘frames of reference’, in particular the many varieties of ‘landmark’ systems typifying the Arctic and sub-Arctic.
Despite the wide variety of languages spoken here (all of them endangered), there is much in common as regards their overlapping geographical settings and the ways in which terms for orientation within the microcosm (the house) and within the macrocosm (the surrounding environment) mesh throughout the region. This is illustrated with numerous maps and diagrams, from both coastal and inland sites.
Attention is paid to ambiguities and anomalies within the systems revealed by the data, as these may be clues to pre-historic movements of the populations concerned – from a riverine setting to the coast, from the coast to inland, or more complex successive displacements. Cultural factors over and beyond environmental determinism are discussed within this broad context.
Les comportements toxiques dans les jeux vidéo en ligne : quelles réponses normatives de la part des autorités publiques et des acteurs du milieu ?
Authors: Burelli Thomas , Bardawil Joseph Alexandre
Published: October 2024

Très souvent caricaturés comme une activité solitaire, les jeux vidéo peuvent au contraire être, dans bien des cas, de formidables catalyseurs d’interactions sociales. C’est le cas en particulier des jeux en ligne qui encouragent les relations sociales entre les joueurs en en faisant parfois un élément essentiel de leur gameplay et de l’expérience vidéoludique. Toutefois, le revers de la médaille de ces jeux en ligne s’appuyant sur des interactions entre les joueurs ou permettant celles-ci réside dans le fait que certains d’entre eux peuvent abuser de ces fonctionnalités et adopter ce qui est communément appelé des comportements toxiques. Il s’agit, par exemple, d’insultes, de menaces ou encore de comportements antisportifs durant les parties. Ces comportements peuvent également être préjudiciables aux éditeurs de jeux et aux plateformes de jeu en ligne puisqu’ils peuvent porter atteinte à leur réputation et encourager certains joueurs à stopper leur pratique. Ceci peut alors se traduire en une perte de revenus pour ces acteurs. Dans ce contexte, nous nous interrogerons sur les manières dont les autorités publiques, dans les principaux marchés des jeux vidéo à travers le monde, et les plateformes de jeu en ligne se positionnent face à ces comportements toxiques. Cette problématique est-elle prise au sérieux? Si oui, pour quelles raisons et quelles sont les mesures mises en oeuvre? De manière plus générale, quelles sont les tendances actuelles en matière de lutte contre les comportements toxiques en ligne?
Praca strunobetonowych belek mostowych typu „T” z kruszywem wapiennym pod obciążeniem długotrwałym i doraźnym
Authors: Biskup Mirosław , Skawiński Jan
Published: October 2024

Rosnące zapotrzebowanie budownictwa na kruszywa oraz coraz większe koszty ich wydobycia i transportu sprawiły, że od dłuższego czasu bierze się pod uwagę możliwość stosowania kruszyw wapiennych w  sprężonych obiektach inżynierskich.
W odpowiedzi na te rozważania podjęto badania prefabrykatów strunobetonowych wykonanych z betonu na bazie kruszywa wapiennego, w celu doświadczalnego zweryfikowania ich właściwości pod względem zgodności podstawowych parametrów materiałowych i konstrukcyjnych z założeniami projektowymi oraz normowymi.
Do badań wytypowano belki strunobetonowe typu T12/2010 wykonane z betonu na bazie grysu wapiennego frakcji 2/8 i 8/16 z kopalni w Sitkówce koło Kielc.
Zakres pracy obejmował badania próbek betonowych oraz badania doraźne i  długotrwałe gotowych elementów prefabrykowanych realizowane na poligonie i  w  laboratorium. Uzyskane wyniki badań wykazały, że beton z kruszywem wapiennym może mieć nie gorsze właściwości mechaniczne od betonów na bazie kruszyw ze skał magmowych, a wykonane z niego belki sprężone spełniają założenia projektowe dla poszczególnych faz pracy elementu.
Ocena odporności asfaltu modyfikowanego na spękania niskotemperaturowe na podstawie wskaźnika koloidalnego
Authors: Budziński Bartosz , Ratajczak Maria
Published: October 2024

Jedną z przyczyn uszkodzeń nawierzchni asfaltowych w regionach świata, gdzie występują ujemne temperatury, są spękania niskotemperaturowe. Aby przeciwdziałać temu zjawisku, projektowane są mieszanki mineralno-asfaltowe (MMA), które mają być odporne na występowanie takich pęknięć. Dobór lepiszcza asfaltowego ma kluczowe znaczenie dla żywotności nawierzchni drogowej i jej odporności na powstawanie spękań. Autorzy w artykule dokonali oceny wpływu rodzaju lepiszcza na odporność niskotemperaturową mieszanek mineralno-asfaltowych. W badaniu wykorzystano kilka asfaltów modyfikowanych, zarówno średnio-, jak i wysokomodyfikowanych (HiMA). Określono podstawowe parametry asfaltów (temperatura mięknienia, penetracja) oraz oznaczono skład grupowy (SARA). Jako kryterium prawidłowego doboru lepiszcza zastosowano wskaźnik koloidalny. Przeprowadzono również testy odporności na pękanie w niskiej temperaturze na mieszankach mineralno-asfaltowych. Badanie przeprowadzono za pomocą metody TSRST. Wyniki pokazały, że zastosowanie asfaltu modyfikowanego poprawia parametry MMA w niskich temperaturach. Zauważono również, że ocena odporności na pękanie w niskiej temperaturze za pomocą wskaźnika koloidalnego nie jest skuteczna  w przypadku asfaltów modyfikowanych; do ich oceny konieczne jest opracowanie innej metodyki badawczej.

This paper provides nine newly proposed notions of intuitionistic fuzzy normal bi-topological spaces (IFNBTS) based on the concept of most explored field fuzzy bi-topological spaces using intuitionistic fuzzy open sets (IFOS). Further, the authors establish implications among the prescribed notions and show that these notions are good extensions of normal and fuzzy normal bi-topological spaces. Finally, the authors study the image and pre-image of IFNBTS, demonstrating that they are also IFNBTS in the sense of IFOS.
Field-road classification for agricultural vehicles in China based on pre-trained visual model
Authors: Zhang Xiaoqiang , Chen Ying
Published: October 2024

Field-road classification that automatically identifies the activity (either in-field or on-road) of each point in Global Navigation Satellite System (GNSS) trajectories is a critical process in the behavior analysis of agricultural vehicles. To capture movement patterns specific to agricultural operations, we propose a multi-view field-road classification method, which extracts a physical and a visual feature vector to represent a trajectory point. We propose a task-specific approach using a pre-trained visual model to effectively extract visual features. Firstly, an image is generated based on a point plus its neighboring points to provide the contextual information of the point. Then, an image recognition model, a fine-tuned ResNet model is developed using the pretraining-finetuning paradigm. In such a paradigm, a pre-training process is used to train an image recognition model (ResNet) with natural image datasets (e.g., ImageNet), and a fine-tuning process is applied to update the parameters of the pre-trained model using the trajectory point images, enabling the model to have both general knowledge and task-specific knowledge. Finally, a visual feature is extracted for a point by the fine-tuned model, thereby overcoming the limitations caused by the small-scale generated images. To validate the effectiveness of our multi-view field-road classification, we conducted experiments on four trajectory datasets (Wheat 2021, Paddy, Wheat 2023, and Wheat 2024). The results demonstrated that the proposed method achieves competitive accuracy performance, i.e., 92.56%, 87.91%, 90.31%, and 94.23% on four trajectory datasets, respectively. Extensive experiments demonstrate that our approach can consistently perform better than the existing state-of-the-art method on the four trajectory datasets by 2.99%, 4.42%, 2.88%, and 2.77% in the F1-score, respectively. In addition, we conduct an in-depth analysis to verify the necessity and effectiveness of our method.

Published: October 2024

Emanuel Syndrome (ES) is a chromosomal disorder characterised by the presence of an extra copy of chromosome 22, specifically a derivative 22 chromosome, which results from an unbalanced translocation involving chromosomes 11 and 22, due to 3:1 meiotic non disjunction. This leads to the gain of the 11q23-qter and 22pter-q11.2 regions. The syndrome is marked by developmental delay, facial dysmorphism, heart defects, genital abnormalities and renal anomalies. In most cases, one of the parents is a carrier of a balanced translocation, t(11;22). The present case is of a two-month-old male child suffering from failure to thrive and developmental delay, who was found to have a karyotype of 47,XY,+der(22)t(11;22)(q23.3;q11.2)dmat, resulting from a maternal balanced translocation, t(11;22)(q23;q11.2). Molecular cytogenetic testing confirmed the presence of partial trisomy 22q11.2 in the proband. This report presents a case of partial trisomy 22q11.2 resulting from a maternal balanced translocation between the long arms of chromosomes 11 and 22, associated with Congenital Heart Defects (CHD) and Congenital Diaphragmatic Hernia (CDH). Approximately, 11 comparable cases have been reported in the Indian population, with variations in breakpoints observed in some. However, none of these previous cases have identified CDH as a phenotypic feature, making this case particularly noteworthy

Anaplastic Large Cell Lymphoma (ALCL) is an uncommon type of Non Hodgkin Lymphoma (NHL). It commonly arises in lymph nodes and can also involve extranodal sites such as the skin, soft tissues, lungs, bones, and liver. Here, a case of Anaplastic Lymphoma Kinase (ALK)-positive ALCL in a 17-year-old male patient who presented with swelling in the frontal and occipital bones is presented. The patient was clinically and radiologically diagnosed with Langerhans Cell Histiocytosis (LCH), and excision of the occipital lesion was performed. Preoperatively, lymphoma was not considered a differential diagnosis. Detailed histopathological examination, immunohistochemistry, and Positron Emission Tomography (PET) scan confirmed the diagnosis of primary bone ALK-positive ALCL. This T-cell NHL is composed of large lymphoid cells with abundant cytoplasm and pleomorphic horseshoe or kidney-shaped nuclei, with characteristic ALK and CD30 positivity. An isolated presentation of ALCL as a primary lesion in the bone is extremely rare. Clinicians and pathologists should be aware of this rare presentation, as prompt diagnosis and proper treatment can lead to favourable outcomes.

Introduction: With the advent of time, the removal of caries has shifted from hand instruments to rotary instruments. A disadvantage of conventional burs is that they non selectively lead to over-preparation. A new polymer bur can be substituted to eliminate these undesirable effects. Aim: To compare and evaluate the efficacy of smart burs and conventional burs in removing infected dentine while preserving affected dentin in carious lesions in primary teeth. Materials and Methods: This was a double-blinded randomised controlled trial conducted in the Department of Paediatric and Preventive Dentistry at Swargiya Dadasaheb Kalmegh Smruti Dental College and Hospital, Nagpur, Maharashtra, India over a period of three months, from August 2023 to October 2023. A total of 40 children aged 6-12 years were selected and evaluated for caries removal efficacy using visual and tactile criteria, which were further confirmed by dye application and numerically scored. Group 1 included 20 children who underwent caries excavation with smart burs, while Group 2 included 20 children who underwent the procedure with diamond points. Statistical analysis was conducted using descriptive and inferential statistics, specifically the Chi-square test. Results: A total of 40 children aged 6-12 years were divided into two groups: Group 1 comprised 11 boys and 9 girls, whereas Group 2 included 10 boys and 10 girls. Of these, 12 cases (60%) showed complete caries removal after the first application of dye, regardless of which burs was used. However, 4 cases (20%) showed some residual caries when using smart burs, while 6 cases (30%) exhibited residual caries with diamond points at the base of the cavity preparation. Additionally, there were 4 cases (20%) with caries present at the base and/or in one wall of the cavity preparation when using smart burs, compared to 2 cases (10%) with conventional burs. Nonetheless, there was no statistically significant difference between the smart burs and the conventional diamond points regarding caries removal. Conclusion: It can be concluded that smart burs are equally effective in removing soft caries compared to conventional methods. Although the results were statistically insignificant, polymer burs were found to be more convenient and can be considered a viable alternative to conventional caries removal techniques.

Arnold Chiari Malformation (ACM) is a group of deformities of the cranium and hindbrain, where there is herniation of cerebellar tonsils through the foramen magnum. Based on the morphology and degree of anatomic defects, Chiari malformations are categorised as type 1, 2, and 3, usually through imaging. While type 2 and 3 are more prevalent and occur in younger age groups, being present from birth, type 1 Chiari is the least severe and is more frequently found in adults. Numerous deformities, including spinal deformity, encephalocele, hydrocephalus, syrinx, and elevated intracranial pressure, are associated with it. Additionally, there are autonomic disturbances associated with it as well. As a result of all these factors, anaesthesiologists face significant challenges. Hereby, the authors present a case report of 52-year-old male patient of ACM type 1 associated with bony deformity at the craniovertebral junction and syrinx, who underwent cervical decompression with C1-C2 fixation. This patient had a tingling sensation and numbness in the left upper limb, with power in the left upper limb being 1/5 and progressive gait abnormalities. Additionally, the present patient had his right upper limb amputated below the elbow joint after a road traffic accident 10 years ago, which imposed more challenges regarding intravenous access. A well-thought-out, multidisciplinary approach is needed for its management. The management of adequate intraoperative anaesthesia in such cases will have an impact on the recovery after surgery of patients with ACM type 1.

Manic episodes, typically associated with Bipolar Affective Disorder (BPAD), can also arise from medical conditions such as thyrotoxicosis, leading to “secondary” or “organic” mania. Thyrotoxicosis, characterised by excessive thyroid hormone levels, can cause neuropsychiatric symptoms and, in severe cases, result in a thyroid storm. Present case is of a middle-aged male patient without a prior psychiatric history who presented with manic symptoms such as overspending, over familiarity, and agitation, alongside physical signs of thyrotoxicosis, including weight loss and tachycardia. He was diagnosed with a thyroid storm secondary to Graves’ disease. Despite the rarity of the condition and the absence of established guidelines, management prioritised controlling sympathetic overactivity and restoring euthyroid status. Lithium, along with antipsychotics were chosen for their minimal impact on the QTc interval, was utilised to effectively address the manic symptoms. Aggressive medical management targeting both thyroid function and manic symptoms led to significant improvement. This case highlights the critical need to consider medical aetiologies in psychiatric presentations and underscores the importance of early diagnosis and multidisciplinary management to reduce morbidity. Collaborative efforts among medical specialties are essential to address the complexities of such cases.
