Introdução: As doenças cardiovasculares (DCV) continuam a ser a principal causa de mortalidade em todo o mundo. A adesão ao tratamento medicamentoso é uma questão importante no manejo das DCV crônicas, influenciando diretamente os resultados e os custos com saúde.
Objetivos: Esta revisão sistemática, apoiada pela Sociedade Brasileira de Cardiologia, avalia o impacto da baixa adesão aos medicamentos cardiovasculares em desfechos clínicos críticos, como morte e eventos cardiovasculares.
Métodos: Foi realizada uma busca abrangente em quatro bases de dados, incluindo Medline, Embase, Lilacs e Cochrane Library. A revisão incluiu revisões sistemáticas com meta-análises que relataram estimativas de risco para a adesão aos medicamentos cardiovasculares. Foram selecionadas quatro revisões sistemáticas, cada uma incorporando estudos observacionais.
Resultados: Os principais achados indicam que um aumento na adesão aos medicamentos reduz significativamente o risco de eventos cardiovasculares, acidente vascular cerebral (AVC) e morte por todas as causas. Especificamente, uma melhoria de 20% na adesão a medicamentos antihipertensivos, hipolipemiantes e outros medicamentos cardiovasculares correlacionou-se com reduções nos eventos cardiovasculares de 7%, 10% e 9%, respectivamente; AVC de 17%, 13% e 18%; e morte de 12%, 9% e 10%. A certeza das evidências foi moderada, sugerindo que esses efeitos provavelmente estão presentes. Esses achados enfatizam a importância de melhorar a adesão ao tratamento medicamentoso para aprimorar os resultados clínicos no manejo das DCV.
Conclusões: As evidências demonstraram reduções em desfechos duros tanto na prevenção primária quanto secundária através do controle de condições como hipertensão e concentrações elevadas de colesterol LDL, bem como os benefícios da terapia antiplaquetária em doenças ateroscleróticas. No entanto, são necessários estudos adicionais para elucidar melhor a relação entre a adesão aos medicamentos cardiovasculares e a melhoria dos desfechos clínicos críticos.

Yapay zekâ ve robot teknolojilerindeki ilerlemeler sonucunda ortaya çıkan ve bugün dünyada birçok evde kullanılmaya başlanan yeni sistemlerden biri otonom olarak çalışıp temizlik yapabilen akıllı robot süpürgelerdir. Kullanıcılarının hayatını kolaylaştıran ve teknoloji konusunda yeniliğe yatkın olan tüketicilerin ilgisini çeken bu cihazlarla ilgili tüketicilerin teknolojiye yaklaşımları konusunda nicel çalışmaların literatürde çok sınırlı görülmüştür. Bu araştırmanın amacı akıllı robot süpürge cihazlarının tüketiciler tarafından kabullenilip kabullenilmediği ve tüketiciler tarafından kabulleniliyorsa, bu teknolojinin hangi yönlerinin tüketicilerin ilgisini çektiğini nicel yöntemler kullanarak ortaya çıkartmaktır. Araştırma verileri çevrimiçi anket yöntemiyle toplanmıştır ve araştırmada kolayda örnekleme kullanılmıştır. Araştırmada Smart PLS paket programı ve yapısal eşitlik modellemesi kullanılmıştır. Araştırma sonucunda algılanan eğlence, algılanan fayda ve algılanan temizleme boyutlarının kullanmaya yönelik tutumu anlamlı ve pozitif etkilediği ortaya çıkartılmıştır. Kullanmaya yönelik tutum boyutunun gelecekte kullanma niyetini anlamlı ve pozitif yönde etkilediği saptanmıştır. Algılanan kullanım kolaylığının ise kullanmaya yönelik tutum üzerinde anlamlı bir etkisi olmadığı saptanmıştır. Araştırmaya ait sonuçlar robot süpürgeleri piyasaya süren işletmelerin, tüketicilerin algıladığı eğlence, algıladığı fayda ve algıladıkları (kullanışlılık) temizleme boyutlarına daha fazla önem vermeleri gerektiğini ortaya koymaktadır.

Published: September 2024

Gelir eşitsizliği ve yoksulluk ülkelerin temel problemleri arasında yer almaktadır. Her ülkenin temel makroekonomik hedeflerinin başında ekonomik büyümenin olduğu dikkate alındığında, gelir eşitsizliği ve yoksulluğun ekonomik büyümeyi nasıl etkilediğinin tespit edilmesi uygulanacak politikaların belirlenmesinde önemli bir husustur. Bu bağlamda çalışmanın amacı, OECD ülkelerinde gelir eşitsizliği, yoksulluk ve ekonomik büyüme arasındaki ilişkinin 2004-2019 dönemini içeren verilerle Sabit etkili Driscoll-Kraay tahmincisi ile incelenmesidir. Çalışmada kullanılan verilerin elde edilebilirliğine bağlı olarak incelenen dönem 2004-2019 olarak sınırlandırılmıştır. Yoksulluk, gelir eşitsizliği ve ekonomik büyümeyi bilgimiz dahilinde Neo-Klasik Büyüme Modeli çerçevesinde ele alan başka bir çalışma bulunmamaktadır. Çalışmada sabit etkili Driscoll-Kraay tahmincisi kullanılmıştır. Bilgimiz dahilinde OECD ülkelerinde bu ilişki bu yöntem aracılığıyla inceleyen başka bir çalışma yoktur. Çalışmanın bu iki açıdan literatüre katkıda bulunacağı düşünülmektedir. Elde edilen ampirik bulgular, gelir eşitsizliği ve yoksulluğun ekonomik büyüme üzerinde negatif bir etkisi olduğunu göstermektedir. OECD ülkelerinde uygulanacak büyüme politikaları, gelir eşitsizliğinin ve yoksulluğunun azaltılmasına yönelik politika bileşenlerini de içermelidir. Diğer bir ifadeyle, yoksulluğu ve gelir eşitsizliğini azaltma stratejileri ekonomik büyümeyi teşvik eden politikalar ile birlikte ele alınmalıdır.
Do High-Frequency Trading Affect Bubble Formation in Stock Markets? Evidence from Emerging Stock Market
Authors: Çelik Mehmet Sinan
Published: September 2024

This study examines the factors that affect bubble formation in the Turkish stock market, Borsa Istanbul (BIST), which is a major emerging market where high-frequency trading (HFT) is a relatively recent phenomenon. The study uses daily stock price data from the period from March 11 2020 to December 31 2020. The data was obtained from Borsa Istanbul. The study finds that HFT transactions play a significant role in bubble formation. HFT transactions can create excessive volatility and manipulation in the market with their high trading volumes and quick trading capabilities. This can increase the risk of bubble formation. The study highlights the importance of regulation and supervision to mitigate the effects of HFT in financial markets. Regulations aimed at increasing transparency in the market can help investors make more informed decisions.

Authors: Kalaycı Oflaz Nihal
Published: September 2024

Sağlık, sürdürülebilir kalkınmanın sosyal, ekonomik ve çevresel tüm boyutları ile ilişki içerisinde olan bir kavramdır. Ekonomik eşitsizliklerin neden olduğu sağlık eşitsizliği; gelir eşitsizliği, sosyal güvenceye erişimde eşitsizlikler, sağlık harcamaları ve pek çok bileşen ile ilişkilidir. Sağlık, sürdürülebilir kalkınma amaçları arasında yer alan tüm hedeflerle ilişkilendirilebilmesinin yanında sağlığın yoksunluğunun neden olduğu eşitsizlikler ya da eşit haklara sahip olamamanın neden olduğu sağlık yoksunluğunu rakamlarla somutlaştırmak oldukça zordur. Bu çalışmada sağlık göstergelerindeki iyileşmeyi hedef alan “Sağlık ve kaliteli yaşam”(SKA3) ve dolaylı olarak sağlığa etkileri bulunan “Eşitsizlikleri azaltma”(SKA 10) amaçlarında yer alan göstergeler aracılığıyla N11 ülkelerinin 2004-2022 yılları arasındaki verileri karşılaştırmalı olarak analiz edilmiştir. Türkiye’nin de içinde yer aldığı bu ülkeler dünyanın en büyük ekonomileri arasında yer alma potansiyeli taşımaktadır. Gelir eşitsizliği, sağlık hizmetlerinin kapsayıcılığı, cepten yapılan sağlık harcamalarına bağlı olarak meydana gelen yoksullaşma, GSYİH içinde iş gücünün payı ve göreli yoksulluk gibi göstergeler incelenmiştir. Veriler doğrultusunda sağlık eşitsizliklerinin azaltılması için en önemli gösterge olan evrensel sağlık kapsayıcılığının artırılması için gelir ve sosyal koruma olanaklarının sağlanması kadar sağlanan bu olanakların sürdürülebilirliğinin de önem taşıdığı görülmüştür. Bununla birlikte, sağlık sistemlerinin toplumun değişen yapısına uyumunun sağlanması, değişen sağlık talebine bireylerin sağlık harcamalarından kaynaklanan finansal yükü artırmaksızın cevap verilebilmesi gibi hususlar evrensel sağlık kapsayıcılığına ulaşılabilmesi ve sağlık eşitliğinin sağlanması için oldukça önemlidir
(In)seguridad energética, infraestructura y criminalización: entre la autogestión de derechos y el poder punitivo
Authors: Hessling-Herrera Franco-David , Gonza Cinthia-Natalia , Durán Pablo-Agustín
Published: September 2024

Introducción: el problema de la seguridad energética ha sido ya abordado desde un enfoque multidimensional, pero siempre asociado a una cuestión geopolítica, de seguridad nacional o de soberanía. La seguridad interna durante el neoliberalismo representa un proceso de inflación del sistema penal. Así, la seguridad energética, incluso desde un enfoque multidimensional, se desdibuja si predomina un enfoque que criminalice a quienes se autogestionan el acceso a los derechos a la vida y vivienda adecuadas, a la energía y a la ciudad. Objetivo: el objetivo principal de este artículo es proponer una nueva forma de comprender el problema de la seguridad energética, llevándola de un concepto estanco a un péndulo entre “seguridad/inseguridad” que sirva para ponderar el grado de goce de esos derechos. Metodología: para ello, se recopilaron, analizaron y sistematizaron los incendios de viviendas entre 2018 y 2023 en una ciudad de 640 mil habitantes (Salta, Argentina) y se cruzó esa información con datos del Registro Nacional de Barrios Populares y de la Municipalidad de Salta. Conclusiones: ello permitió concluir que reapropiarse de la “seguridad energética” como escudo para garantizar el acceso a derechos es un terreno fértil no sólo a los fines académicos, sino también jurídicos, sociales y políticos.

Authors: Jin Sun Cha , Tae Woo Kim , Yeon Sook Lee , Byeong Kon Kim , Soo Kwan Jang
Published: September 2024

This study investigated factors influencing the flowability of zeolite using three types of commercial zeolites with low flowability – Zeolite-beta, Zeolite-Y, and ZSM-5 - and manufactured a device applying piezoelectric energy to measure their apparent density. Zeolite properties such as flow function (FF) and cohesion by Powder Rheometer, elemental analysis by XRF, specific surface area, pore characteristics, and shape of zeolite particles by FE-SEM, average particle size and size distribution by particle size analyzer were analyzed. Low flowability zeolite could pass through a mesh hole moved by piezoelectric energy. The apparent density measured by the device applying piezoelectric energy was found to be more uniform with a smaller standard deviation than existing density measurement equipment.

Published: September 2024

En este artículo se presenta una modalidad de evaluación formativa con el objetivo de plantear otra mirada sobre los procesos de enseñanza desde la aplicación de estrategias para el aprendizaje significativo. La experiencia se ha puesto en práctica en la unidad curricular Planeamiento en el Área de la Información, dictada en las licenciaturas en Archivología y en Bibliotecología en Uruguay. Mediante un parcial de carácter procesual, se busca que se comprendan los contenidos del curso a través de su aplicación a un plan estratégico. Se analiza su desarrollo en el periodo 2021-2023 y se integra la mirada de los estudiantes y de las docentes de la unidad curricular. Estos insumos se integran a su vez en la evaluación de la herramienta del parcial que el equipo docente realiza y a partir de allí se hacen ajustes y modificaciones. El paradigma de la cognición situada —en el que el estudiante es activo protagonista de su propio proceso de aprendizaje— y el aprendizaje cooperativo como forma de integrar saberes desde la construcción colectiva constituyen la base teórica. En las conclusiones se comparten argumentos que permiten calificar esta modalidad de evaluación como una buena forma de poner en tensión los aprendizajes desarrollados en el aula, de cara a la formación de profesionales críticos.
On Gamma-Gompertz-Makeham Assurances and Life Annuities
Authors: Castellares Fredy , Patricio Silvio , Lemonte Artur
Published: September 2024

We focus on the gamma-Gompertz-Makeham model, and derive useful structural properties for this mortality model. We provide the basic properties like moments, remaining life expectancy, single life annuity, among many others, in closed form, and so it eliminates the need of evaluating them through numerical integration directly. The estimation of the gamma-Gompertz-Makeham model parameters is performed by using the maximum likelihood method under the traditional discrete Poisson distribution, as well as under the recently introduced discrete Bell distribution, which is an interesting alternative to the usual Poisson distribution, mainly in the presence of overdispersion. We illustrate the performance of the gamma-Gompertz-Makeham model in a human mortality database, and compute, based on the Poisson and Bell distributions, the remaining life expectancy, single life annuity and single assurance at ages 30, 55, and 80 in France, Italy, Japan, and Sweden, from 1947 to 2020 males and females separately.

Varicose Veins as Model for Apportionment among Risk Factors for Compensation Purposes
Authors: Weber Marc J. , Taragin Mark I.
Published: September 2024

Objective.—

To demonstrate a method which is being used to apportion between risk factors for occupationally related disease and compensate individuals with multiple risk factors. The application to individuals will be demonstrated for varicose veins.

Background.—

The National Insurance Institute (NII) is tasked with compensating work related injuries and illness in Israel. Population attributable fraction (PAF) has been utilized in order to estimate the amount of disease that can potentially be eliminated in a population through the elimination of individual risk factors. PAF is based on relative risks and the prevalence of these risks.

Methods.—

A review of the medical literature consisting of epidemiological studies of varicose veins and its multiple risk factors was conducted, with special attention to prolonged occupational standing. Summary, weighted, relative risks were calculated for eight different risk factors. The proposed formula then allowed for apportioning among those risk factors in the individual.

Results.—

The findings of the current study indicate that prolonged standing may be associated with the presence of varicose veins, however in light of the multiple other risk factors associated, its overall contribution is generally minor.

Conclusion.—

Apportionment among multiple risk factors for varicose veins can be accomplished mathematically in individuals. This application is being applied successfully for other diseases as well.
Being Like Others - Reconstructing the Experiences of a Woman on the Autism Spectrum
Authors: Urbaniak-Zając Danuta , Głowala Magdalena
Published: September 2024

Introduction: According to the idea of neurodiversity, autism is an expression of biodiversity. It is widely believed to occur more often among boys than girls. According to women on the spectrum, their rarer diagnosis is, on the one hand, a consequence of diagnostic criteria that are inadequate for the female autism profile, and on the other hand, the influence of socio-cultural factors: the socialisation and upbringing of girls causes them to a greater extent to be submissive and compliant, to meet imposed expectations. As a result, they acquire the ability to hide, to mask their symptoms of autism, and this behaviour often blocks their development. Research Aim: The cognitive aim of the study was to reconstruct the behaviour of women on the autism spectrum in order to hide their symptoms of being non-neurotypical in everyday social interactions. The practical aim was to “give voice” to women on the spectrum, because usually this “voice” is silenced by professionals that “know better”, are more “objective”. Method: The research technique used in the study was the narrative interview (in the F. Schütze’s version). It was interpreted using the methodological guidelines of objective hermeneutics. This paper presents an in-depth interpretation of one of the 7 interviews with women on the autism spectrum (volunteer-targeted research sampling was used). Reconstructing patterns of action required revealing latent meanings. Results: Three masking behaviours were reconstructed: the study participant’s exact imitation of her friend’s behaviour; seeking to gain a profound knowledge of the circumstances of a future social encounter in as much detail as possible; engaging in self-harming behaviour that nevertheless allows one to explain one’s own behaviour in a socially acceptable way, while covering up the real reasons for it. During the interview an important issue that was not planned came to light, namely the circumstances under which the masking was abandoned. Conclusion: Masking behaviour of autism symptoms blocks the individual development of women on the spectrum. It is worthwhile to devote further research to identifying the circumstances that promote the resignation of masking.
Parental Competencies of Mothers of Visually Impaired Children Receiving Early Development Support
Authors: Kucharczyk Izabella
Published: September 2024

Introduction: Parental competencies are a certain acquired disposition of parents that provides them with the opportunity to choose such strategies that will aid their child’s development, increase the child's knowledge, autonomy and self-regulating processes. The arrival of a visually impaired child often changes the functioning of the entire family, but it also affects the parents' ways of acting, their control mechanisms and their sense of self-efficacy. Their internal and external resources as well as their parental competencies will determine the effectiveness of therapies in the field of early development support. Research Aim: The aim of the study was to determine the level of parental competencies of mothers of children receiving developmental support, in this case children with impaired vision. Research Method: The study included a group of 37 mothers of children with visual disabilities receiving early development support. The Parental Competencies Test (Test Kompetencji Rodzicielskich, TKR) by Matczak and Jaworowska (2017) was used to assess the level of parental competencies. In addition, a questionnaire for parents. Results: The study showed that the surveyed mothers with children with visual disabilities are characterised by an average level of granting freedom to their children, they set realistic requirements, teach and explain the behaviours. They are also characterised by an average level of commitment, i.e. they are interested in their child, show positive feelings and acceptance of the child’s behaviour, are supportive and ready to provide the necessary help. Within the range of scales indicating the occurrence of mistakes, it can be stated that in the scales of rigour, permissiveness, overprotectiveness and helplessness, the examined mothers achieved average results. Conclusions: Although the presented results indicate a tendency for the surveyed mothers to educate themselves, it would certainly be necessary to consider the creation of a support network, prevention programmes and training cycles, thanks to which these mothers would have the opportunity to improve their parenting competencies and to learn how to eliminate their mistakes.

Published: September 2024

In this study, the microstructural evolution of the microstructure and phase transformation of the biomedical Ti-6Al-4V alloys fabricated by Selective Laser Melting (SLM) at various solution treatment temperatures was investigated in order to achieve the formation and stabilization of (α + β) lamella structure for the final products. Solution heat treatments were conducted at 850℃ for 2.5 hours; at 950℃ or 1020℃ for 1 h and followed by cooling naturally in the oven. The α' martensite in the SLMed samples was transformed from the β phase after heat treatment and finally achieved the uniform (α + β) lamella structure in heat treated samples of Ti-6Al-4V alloys. The dependence of the transformation behavior of the β phase during the solution treatment was determined by the partitioning of α and β stabilizing elements.

Service robots are of paramount importance in both industrial and residential environments. Nevertheless, these robots frequently encounter obstacles in the form of perilous elements present in their surroundings, which may result in their malfunction and hinder their optimal performance. Hence, autonomous robot applications heavily rely on coverage path planning algorithms, which facilitate the execution of area coverage operations in a streamlined and economical manner. The article presents a coverage path planning algorithm for service robots that is based on a backtracking procedure. The proposed method attempts to strike a balance between the safety of the cleaning automaton and the extent of coverage. Following straight-forward instructions, the mobile robot (MR) initially generates a spiral or zigzag trajectory. It examines each position for possible backtracking locations. When obstacles and visited positions obstruct the path, the improved A* algorithm is utilized to return to known unvisited regions. Subsequently, the robot proceeds to sweep the regions until no remaining back-tracking sites remain. Simulation of the method on the Robot Operating System (ROS) verifies that it is possible to restrict the movement of high-risk robots.

Increasingly, the fabrication of steel components is being done via 3D metal printing. One of the most commonly utilized reliable and precise methods is called selective laser melting (SLM), and it involves the use of metallic powder as the material that is fed into the laser. One of the famous problems that SLM technicians face is the roughness of the printed parts. The goal of this paper is to study the effect of tumbling on the M300 maraging steel, which was produced by using a Renishaw AM500 3D SLM printer. An examination of a procedure that is both cost-effective and efficient for manufacturing and surface treatment is carried out within the scope of this research. The post-processing was investigated in depth, which resulted in 2D surface roughness Ra = 0.39 µm and 3D surface roughness Sa = 0.4 µm. The topography and morphology of the specimens were checked. Additionally, the surface wettability was tested, and it was seen to display wetting behavior, the improvement in surface wettability caused a better surface energy.

Mobile robots (MRs) are exerting a significant influence in industrial as well as residential settings. Concurrently with the escalating advancement of technology, the incorporation of artificial intelligence algorithms into the obstacle evasion issue of MRs is gaining increasing attention. The paper utilizes Deep Reinforcement Learning (DRL) to a MR that is furnished with a camera. Images captured by a stereo camera will be inputted into the YOLO-v8 model to identify obstacles situated in the path of the MR. Subsequently, the distances to these obstacles will be regarded as the state of the MR. The information was utilized to train a Deep Q-Network. Throughout this training process, the system acquires the capability to determine suitable actions for the MR to advance towards the destination while circumventing obstacles. Each action executed by the MR is accompanied by a reward, with the path yielding the most desirable outcome receiving the highest reward. The outcomes of the simulations conducted on the Robot Operating System 2 (ROS2) corroborate the effectiveness of this Deep Reinforcement Learning technique for the task of obstacle avoidance.

This study delves into the comparative analysis of vibrational tumbling and electrolytic polishing, two distinct surface finishing techniques, on the surface roughness parameters of additively manufactured Inconel 718 alloy. Surface roughness significantly impacts the functionality of components, especially in aerospace and automotive applications where Inconel 718 superior mechanical properties are sought after. Vibrational tumbling relies on mechanical abrasion, while electrolytic polishing utilizes chemical processes, offering different pathways to attain smoother surfaces. Three samples were individually subjected to vibrational tumbling, electrolytic polishing and combination of both to determine its effects on surface roughness parameters Sa, Sq, Sp and Sv, evaluated via surface profilometry. Surface wettability was also determined for all the formed surfaces to evaluate the surface nature and functionality. The results indicated that the areal roughness parameter values ranged from Sa = 5.68 to 3.38 µm. The maximum surface height parameter varied from Sz = 53.36 to 32.44 µm, while the maximum valley height Sv ranged from 29.418 to 18.026 µm, and the maximum peak height Sp varied from 23.942 to 14.418 µm across all the printed samples. The findings showed a decrease of 32%, 12% and 42% for vibrational tumbling, electrolytic polishing and combination of both, respectively in the surface roughness values from as built samples. Further, the surface wettability results showed increase in the hydrophilic nature of the surface for each treated surface. The results furnish valuable insights into the efficacy of each method in enhancing surface quality, aiding in informed selection of the optimal surface finishing technique for additively manufactured Inconel 718 components.
In Defense of Abused Women: Rural Critical Criminology in the Courtroom
Authors: DeKeseredy Walter S.
Published: September 2024

Many critical criminologists assert that criminal courts only function on behalf of powerful interests. Nothing could be further from the truth. Drawing heavily on my recent work as an expert witness assisting rural battered women in conflict with the Kentucky legal system, the main objective of this paper is to show that a courtroom can be a site of progressive struggle and resistance. Indeed, the courtroom is what the late Ian Taylor defines as a “political place,” and this paper demonstrates that positive outcomes for incarcerated abused women can occur when rural critical criminologists enter this space.

Armed banditry and insurgency are among the principal insecurity challenges in present-day Nigeria. This study investigated the lived experience of male pastoralists on rural banditry and associated economic crimes in Kwara State, north-central Nigeria to fill identified gaps in the literature. A sample of 20 pastoralists’ hamlets was selected for the study. Data were collected through focus group discussions and key informant interviews. Qualitative content analysis was used to analyse the data. Data analysis showed that study participants were aware of the problem of rural banditry. Major banditry-related economic crimes reported by participants were robbery and burglary, livestock rustling, farmers-herders conflicts with attendant destruction of pastoralists’ assets, among others. Through facilitation by pairwise ranking exercise within focus group sessions, study participants identified livestock rustling as the most important banditry-related economic crime. Participants carried out social profiling of livestock rustlers. Results further suggested that the key factors influencing livestock rustling were economic deprivations and social dislocation in Nigerian society, criminal networks on livestock rustling and illegal trading on rustled livestock, and access to light weapons by the livestock rustlers, among others. Participants reported the immediate and long-term effects of livestock rustling on the crime victims and their communities. The study recommends the rollout of the government-planned National Animal Identification and Traceability System, the enactment of state law that would prohibit indiscriminate livestock transportation and, the creation of a local security system to complement the state-based policing system to reduce armed banditry and livestock rustling among the study population.
Design Supply Cycle for Inventory Management

Published: September 2024

In each company within the application of the lean principle for the material flow area, the inventory management is essential. The subject of this paper is to describe the application of differentiated inventory management. Some businesses have a large number of warehouse items, and it is therefore necessary to identify and work with inventory information. In terms of logistics, it is important to take into account the general rule, which is to keep the amount of inventories at minimum, as well as, the principle of minimising any unnecessary waste. The main purpose of the inventory management is to determine which items are important for the company. The aim of the paper is to demonstrate that the implementation of inventory management could contribute to an increase of certain sales aspects of the company. This article applies a case study scenario in order to analyse a logistics company's sales records, from the sale of car components. The final parts the article provides a comparison of the improved situation within company, in terms of monitored sales parameters. The comparison includes parameters such as the number of deliveries, speed of delivery, and the number of distributed quantities before and after the implementation of differentiated inventory management model.
A Survey of Public Library-Led Digital Literacy Training in Canada: Perceptions of Administrators and Instructors
Authors: Detlor Brian , Serenko Alexander , La Rose Tara , Julien Heidi
Published: September 2024

Objective – This paper presents the results from a survey of administrators and instructors at public libraries across Canada investigating the delivery of digital literacy training led by public libraries. The goal of the survey was to capture a snapshot of the Canadian public library-led digital literacy training landscape and to explore differences in perceptions of training activities between public library administrators and instructors.
Methods – An online survey was distributed to administrators and instructors at public libraries across Canada with the help of two national public library associations. The survey instrument was developed based on a theoretical framework from the research team’s prior case study investigations of community-led digital literacy training. The survey included closed- and open-ended questions concerning the availability of adequate/sustained funding, the adequacy of dedicated classroom resources, the competency of teaching staff, the helpfulness of support staff, the amount and frequency of knowledge sharing of best practices, the amount of rigorous and regular performance measurement, the scheduling of the training provided, the skills taught, the pedagogical approaches used, and the marketing carried out. Responses were analyzed using both quantitative and qualitative data analysis techniques.
Results – Public library administrators and instructors in Canada are generally satisfied with the delivery of digital literacy training; however, room for improvement exists. Instructors are more positive about the delivery of this training than administrators. Findings support and extend the research team’s conceptual model, specifically in terms of providing more insight and clarity on how the learning environment and program components affect the delivery of digital literacy training led by public libraries. Results highlight how training is situated in context and how libraries need to fine-tune the delivery of this training in ways that are reflective of libraries’ learning environments and program components.
Conclusion – Results are of high interest to researchers and library practitioners who wish to leverage evidence-based library and information practice to understand and address the factors affecting the successful delivery of public library-led digital literacy training. Though funding is always an obstacle for any public service organization, libraries can make improvements to the delivery of their training in other ways, such as carrying out more robust performance measurement and using results more transparently, participating in more knowledge-sharing opportunities, and better understanding learner needs and preferences.
Ethnographic Study Found School Library is a Safe Refuge of Solitude for French Urban Middle School Students
Authors: Shen Lisa
Published: September 2024

A Review of:
Joing, I. (2023). The school library: An important place for adolescents’ well-being. An ethnographic experience in a French middle school. Journal of Library Administration, 63(6), 777-796. https://doi.org/10.1080/01930826.2023.2240192
Objective – To understand the role of school libraries in middle school students’ well-being.
Design – Ethnographic study consisting of overt participant observation, semi-structured interviews, and a written questionnaire.
Setting – An urban middle school in northern France between November 2017 and April 2018.
Subjects –Students from 10 to 15 years of age and selected school personnel.
Methods – Students from three randomly selected classes were invited to complete the questionnaire, and quantifiable responses were summarized using descriptive statistics. Other materials collected during the five-month study period, including the researcher’s field journal, interview transcripts, and qualitative questionnaire responses, were analyzed using grounded theory-informed open, axial, and selective coding to discern students’ perception of the library.
Main Results – The majority of the 95 students who completed the questionnaire viewed the library as a safe place associated with positive school experiences. However, these favorable impressions gradually decreased as students progressed in their studies, with senior (fourth-year) respondents reporting the lowest positive-to-negative experience ratio, at 1.1 to 1. Thematic clusters that emerged from coding of the rest of study materials further supported these findings, showing that students perceived the library to be both (a) a physical shelter from harsh winter elements during recess or lunch, and (b) a psychological refuge for solitude and peace from negative peer interactions. Nonetheless, (c) limited and unreliable library hours and (d) restrictive rules concerning noise and space access appeared to erode these positive associations over time. Senior students also expressed (e) the desire for more library or general school spaces dedicated to group work. 
Conclusion – Findings from this ethnographic study highlighted different ways library space contributed to students’ sense of well-being. The study also uncovered some shortcomings in space management that contributed to students’ declining library use and positive perception over the course of middle school. The researcher recommended extending library hours and expanding the diversity of library activities to ensure the space would serve as a welcoming environment not only for students seeking solitude, but also for those desiring more peer collaborations and social connections.
