Effect of calcium on fruit quality: A review
Authors: Jaime-Guerrero Marilcen , Álvarez-Herrera Javier Giovanni , Fischer Gerhard
Published: June 2024

Calcium (Ca) plays a crucial role as a nutrient influencing the ripening, post-harvest duration, and quality of fruits. Its impact on the cell wall and its function as a secondary messenger at the cellular level underscore its significance. While recently there has been an increase in studies examining the effects of Ca on fruit quality, there remains a need to consolidate and expand the literature on pre-harvest and post-harvest applications of Ca concerning the physical-chemical properties of fruits. This review aims to compile information on the mechanisms of Ca absorption by plants, as well as the interaction of Ca with the cell wall in fruit development and growth; the review also aims to synthesize literature on the effects of calcium on the physical and chemical properties of fruits that ultimately influences their quality. The review considers a comprehensive analysis of studies published in reputable scientific publishers (Elsevier, Springer, Frontiers, Wiley, MDPI, Hindawi, SciELO) over the last ten years, encompassing various relevant topics. Calcium proves effective in retarding the loss of firmness in fruits, increasing their mass, mitigating mass loss during storage, and extending postharvest life, thereby enhancing marketability. Furthermore, Ca demonstrates a role in decreasing the activity of enzymes responsible for cell wall degradation. Additionally, it reduces ethylene production in fruits, delaying the climacteric peak and reducing its intensity. Its application results in delayed color changes in fruits. For soluble solids, Ca diminishes sugar values and postpones their peak during the post-harvest period while maintaining high total acidity values. Notably, Ca applications contribute to a decreased incidence of certain physiological disorders.
El rodaje de Estado de sitio en Chile: debates de izquierda y tensiones sobre la imagen internacional de la Unidad Popular (1970-1973)
Authors: Campos-Pérez Marcy
Published: June 2024

el artículo aborda la filmación en Chile de Estado de sitio (1973), una cinta del cineasta franco-griego Costa-Gavras, inspirada en una operación realizada por la guerrilla urbana en Uruguay a inicios de los años de 19 70. Filmada en el contexto de la Unidad Popular, en 1972, las estrategias políticas representadas en la película suscitaron una fuerte crítica de la izquierda chilena, particularmente del Partido Comunista. Nuestro propósito es identificar dichas discusiones que emergieron a la luz de este rodaje. Por una parte, las tensiones subyacentes a la llamada “vía chilena al socialismo” y por otra, el debate acerca de la imagen que debía proyectar este proceso en el extranjero. Por cuanto proponemos una perspectiva de análisis transnacional, el artículo se estructura a partir del diálogo de múltiples tipos de fuentes primarias (archivos diplomáticos, cinematográficos y prensa periódica), procedentes de distintos espacios (especialmente Chile y Francia). Este tipo de estudio, centrado en la producción y la recepción cinematográfica, permite comprender un contexto de tensiones más amplias, relacionadas con la Guerra Fría en América Latina, conectando la escala local, regional y global. A pesar de las divergencias, veremos que este proyecto cinematográfico originó diferentes conexiones político–culturales, cuyas repercusiones se extendieron incluso luego del golpe de Estado chileno de 1973.

Authors: Restrepo-Espinel Gloria , Torres Moreno Miguel Eduardo , Aponte-Melo Jairo
Published: June 2024

Information technologies (ITs) provide optimization, service improvement, and a higher level of competitiveness, adding value to organizations’ strategic results and enabling the implementation of digital transformation initiatives. However, organizations must achieve high alignment between business and IT strategies in order to maximize these contributions. Researchers have proposed various methods to improve alignment and have created measurement instruments to assess it within an organization. One of the most recognized is Luftman’s SAM model (strategic alignment maturity model), which has a scale of five alignment levels and evaluates six dimensions. This work assesses the degree of alignment between business and IT units within a healthcare entity in Villavicencio (Colombia) using the Luftman instrument. The results indicate that the organization has a maturity level of 2, which denotes a low alignment. The organization needs to strengthen its IT unit and increase its participation in strategic planning.

Authors: Steiner Alexandre Arns , Franco David Gabriel de Barros , Nara Elpídio O. B. , Steiner Maria Teresinha Arns
Published: June 2024

All public administration contracts must be evaluated in order to improve their performance while respecting the limits established by laws and regulations. The purpose of this article is to apply an approach to improve the performance of a common building maintenance service contract for the Paraná State Court of Justice (PRCJ), which has a total built area of ​​544 283,79 m² in 224 buildings distributed over 161 counties, by optimizing the territorial partitioning of Paraná State. To partition the state into 14 regions, a binary integer linear programming (BILP) mathematical model is applied to the facilities location problem (FLP) in three scenarios. The results show that Scenario 3 (in which the location of the 14 maintenance offices and the configuration of their areas of activity were optimized) is the best in terms of minimizing the distances traveled by maintenance teams. In this scenario, the total distance traveled would be 9 775 km per day (instead of the current 11 150 km), achieving savings of around 12,3% when compared to the current solution. With this solution, in addition to the distance, the direct and indirect costs associated with the displacement of work teams and the time spent on their corresponding trips would be minimized. Furthermore, the users of maintenance services could be served more quickly, resulting in a higher number of services and greater satisfaction for the target audience of the contract.
Lessons Learned from Construction Site Layout Planning Practices
Authors: Hansen Seng
Published: June 2024

Proper layout planning is necessary to prepare a site for construction activities, prevent potential delays, and ensure project safety and security. Despite the considerable amount of studies regarding construction site layout planning, most research has relied on fabricated data using simulations, while, in fact, site layout is unique for each construction project, and its planning requires previous experience. This paper presents an in-depth study on site layout planning practices, as observed in four actual project cases. Using an empirical case study approach, these practices are collected through site observations, document examinations, and semi-structured interviews. Several discussions related to site layout planning practices are described, including the considerations, types, tasks and benefits related to proper site layout planning. The contribution of this paper is the ability to capture some lessons learned regarding construction site layout planning from actual project cases, which can be utilized by other parties for the benefit of future projects. The lessons learned allow developing appropriate strategies required by construction project teams in order to increase their response capability and hence be able to proactively make decisions regarding proper site layout planning.
MODELOS DE INTERACCIONES ATÓMICAS EN MECÁNICA MOLECULAR
Authors: Díaz Miguel , Coll David , Vega David
Published: June 2024

Esta revisión describe modelos de interacciones atómicas utilizados en la mecánica molecular, enfatizando consideraciones que se deben tener en cuenta para su implementación computacional. Estos modelos constituyen los términos de una función que aproxima la superficie de energía potencial de un sistema molecular, conocida como campo de fuerzas. Existen dos grupos de interacciones: enlazantes y no enlazantes. La primera categoría contempla potenciales estiramiento de enlace, flexión de enlaces, torsión de enlace y flexión respecto a un plano molecular. La segunda categoría contempla potenciales electrostáticos y de van der Waals. Las interacciones electrostáticas son descritas mediante la ley de Coulomb, requiriendo una metodología de asignación de cargas. Las interacciones de van der Waals son modeladas mediante términos de largo alcance asociados a la interacción entre dipolos inducidos, y mediante términos de corto alcance asociados a la improbabilidad de encontrar electrones con el mismo espín en el mismo lugar del espacio.
Mucocutaneous lesions associated with lymphoproliferative disorder: a case report
Authors: Borda-Pedraza Katherin Andrea , Arias-Pedroza Viviana Leticia , Quinche-Pardo Mauricio Ernesto
Published: June 2024

Introduction: Leukemia is a type of blood cancer characterized by the accumulation of mature or immature cells in the bone marrow (BM), peripheral blood, lymph nodes, and lymphoid tissues. These cells can cause extranodal infiltration in tissues such as skin (leukemia cutis [LC]) and mucous membranes, being these locations rare.
Case presentation: The patient was referred to a university hospital, where BM and computed tomography tests were performed, showing peripheral lymphatic involvement and maxillary paranasal sinus (PNS) opacity. Subsequently, functional endoscopic sinus surgery (FESS) of the PNS was performed and biopsies were taken from the skin lesion and PNS mucosa. Based on the results of the BM tests, the patient was diagnosed with B-cell acute lymphoblastic leukemia, so chemotherapy (CT) was initiated. The biopsy report described infiltration of leukemoid neoplastic cells in both locations (skin lesion and PNS mucosa), confirmed by immunohistochemistry. During CT, the patient developed bone marrow aplasia, tumor lysis syndrome and septic and hypovolemic shock, which eventually led to his death.
Conclusion: LC is a rare condition associated with poor prognosis, so once detected it is necessary to initiate systemic treatment and look for possible extramedullary metastases. PNS opacity in patients with oncologic immunosuppression is usually considered as nasosinusal infection; however, it may also be secondary to an unusual infiltrative involvement of leukemia.
'Secret' Teachings of a Transnational Yoga and Tantra School
Authors: Olsson Tova
Published: June 2024

This article will present a pilot study on the Romanian school of yoga and tantra, MISA. MISA, or the Movement for Spiritual Integration into the Absolute, has gained reputation as a controversial organization through the last decades as its leader, Gregorian Bivolaru, has been accused of sexual misconduct and human trafficking on several occasions and is currently wanted by Interpol. Yet his influence is spreading through European yoga studios as people enter MISA (often unknowingly of the organization’s problematic past), expecting esoteric and authentic teachings on yoga and tantra. This article will use a textual analysis of the material handed out during two year-long MISA yoga and tantra-courses, to examine the foundational teachings of a transnational yoga school in constant expansion, and how they relate to a broader religious-historical context of modern yoga and tantra, taking into special consideration the use of secrecy, claims of authenticity and the construction of gender. The article shows that, on the surface, MISA resembles many other contemporary schools of yoga and tantra, while a closer look reveals an emphasis on sexual continence that stands out, assuring the continuous reputation of the organization as both provocative and tantalizing.
Yoga in Communist Poland
Authors: Kozłowiec Iwona
Published: June 2024

This article explores the popularization of yoga by Tadeusz Pasek (1925–2011). His characterization of yoga as ‘relaxation and concentration exercises’—cwirki—allowed practices derived from yoga to gain popularity in communist Poland. Classes were officially taught through the centres of the Society for the Propagation of Physical Culture (TKKF), a state institution funded by the communist authorities. Details of these classes were published in 1973 by the State Medical Publishing House (PZWL) in Theory and Methodology of Relaxation and Concentration Exercises. Pasek created a system of instructor training and certification within the framework of the TKKF, coordinated on a national level. He innovated model ‘calming centres’, combining TKKF structures within state-run housing cooperatives, functioning as yoga studios, community centres, and venues for psychiatric rehabilitation after in-patient treatment. Pasek introduced relaxation and concentration exercises for the rehabilitation of patients with neurotic disorders. Consequently, yoga practices, smuggled under the official name of relaxation and concentration exercises, entered academic circles of scientists and doctors, and also popular culture. Although its popularity waned as more yoga schools established themselves in Poland after 1989, Pasek’s innovation of culturally embedding the practices established a foundation for the development of many yoga traditions in post-communist Poland.

Published: June 2024

In this work, a bifunctional nanocomposite based on silver and iron oxide nanoparticles (AgNPs/Fe3O4) was prepared and then used as SERS substrate (surface-enhanced Raman spectroscopy) for sensing diclofenac which is one of the most widely used non-steroid anti-inflammation drugs. AgNPs/Fe3O4 nanocomposite was synthesized by combining co-precipitation of iron oxide and in-situ reduction of silver nanoparticles. Morphology and structural studies revealed a conjugated structure in which silver nanoparticles (80 nm in diameter) were surrounded by iron oxide nanoparticles (18 nm in diameter). There is a slight blue-shift in position of plasmon peak from 405 nm for silver nanoparticles to 375 nm for AgNPs/Fe3O4 nanocomposite. Even the saturation magnetization (Ms) of the Ag/Fe3O4 nanocomposite only reached 28 emu.g-1 but still good enough for immobilizing nanocomposite structures onto the substrate. The use of AgNPs/Fe3O4 nanocomposite as SERS substrate for sensing application was demonstrated with using diclofenac as a model. The detection limit and enhancement factor of the SERS-based diclofenac sensor were found to be 10-12 M and 2.6×1010, respectively. Such kind of bifunctional nanocomposite will probably help us to avoid time-consuming process to immobilize metal nanoparticles onto the surface, and also allow us to regenerate the substrate for multiple uses.

Published: June 2024

In the first years after World War II, the effects of the war were eliminated, industry was nationalized, agriculture was collectivized, and annexed areas were merged with the rest of the country. In Lower Silesia, the Polish authorities wanted to implement a development plan. To this end, it was necessary to launch and develop industrial and agricultural production and to prepare means of transport and communication. The task was difficult because the new terrain required solving the problems of social issues, ordering and activating industry and taking initiatives in the area of educational and cultural life. The establishment of enterprises and industrial plants in Lower Silesia was associated with the preparation of an educational and cultural offer for employees, which took the following forms: libraries, common rooms, reading rooms and dance, theater, music, ballet and company orchestras. An important role in the above activities was played by the media: newsreel and Lower Silesian press. They published information about the initiatives of the management of workplaces in the direction of promoting the activity of spending free time by workers and the creation of new places for the development of interests and opportunities for innovative activities. The economic development of the Recovered Territories after the war took place in complex political and social conditions. The problem was the post-war chaos and the limited possibilities of the state, which did not have adequate financial and material resources that had to be allocated for reconstruction. The aim of this article is to present educational initiatives in factories and plants in Lower Silesia after World War II. Drawing attention to the implementation of ideological and political assumptions through the prism of cultural activities with the use of local press.

The participation of the Catholic Church in the systemic changes in Poland is unquestionable. The significant role of church hierarchs, middle- and lower-level pastors in accelerating the erosion of the communist dictatorship in Poland over the years, and especially in the last decade of the Polish People’s Republic, is unquestionable. Analogous processes of political, social, economic and cultural changes taking place in neighboring countries where Catholicism was the dominant religion were also stimulated to a large extent by representatives of the clergy. However, the issue of the importance of the Orthodox Church in the Soviet Union for the systemic changes at the end of the 1980s remains slightly more complicated. Therefore, the article compares two powerful Churches, Catholic and Orthodox, from the point of view of analogy and diff erences in the role, influence and importance of these institutions for the collapse of both authoritarian systems.
KDM6A Promotes Angiogenesis, Migration, and Invasion of Pancreatic Cancer by Activating LAMP3
Authors: Fan Sunfu , Xu Liang , Xie Dafei , Yu Bingqi
Published: June 2024

Lysine demethylase 6A (KDM6A) is abnormally expressed in various cancer. This study aimed to investigate the potential of KDM6A in pancreatic cancer (PC). mRNA expression was calculated by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). Protein expression was detected by Western blot. Cell viability was measured by Cell Counting Kit (CCK-8) assay. Cell angiogenesis was determined by tube formation assay. Cell migration and invasion were determined by Transwell assay. We found that KDM6A was upregulated in PC patients and cells. Interestingly, KDM6A deficiency inhibited the proliferation and angiogenesis of PC cells. Moreover, KDM6A knockdown suppressed the migration and invasion of PC cells. Additionally, KDM6A upregulated the expression of lysosomal associated membrane protein 3 (LAMP3) via driving demethylation of H3K27me3. Overexpression of LAMP3 reversed the effects of KDM6A knockdown and contributed to the angiogenesis and aggressiveness of PC cells. In summary, KDM6A-mediated demethylation of tri-methylation at lysine 27 of histone H3 (H3K27me3) promotes the transcription of LAMP3, resulting the angiogenesis and aggressiveness of PC. Therefore, targeting KDM6A may be an anti-angiogenetic strategy for PC.

Authors: Civelek Mehmet
Published: June 2024

Financial performance of SMEs (small and medium-sized enterprises) plays a crucial role in bank credit access of these enterprises and the economies of countries where they operate. However, firm’ executives' Resource-based View (RBV) characteristics can differently affect financial performance of SMEs that they manage, therefore, credit access of SMEs can differ. In this regard, this paper purposes to analyze whether the impact of financial performance on bank access to finance differs depending on executives’ educational status, gender and sectoral experience or not. In line with this aim, this research collects data from 479 randomly selected respondents by directing an online questionnaire. After that, the research data is analyzed by employing a Binary Logistic Regression Test. According to the results, the impact of financial performance on credit access differs depending on gender and sectoral experience of firms’ executives. However, educational status of firm executives does not play any role in the impact of financial performance on access to finance.

Understanding The Lived Experiences of Black Female College Athletes and Factors that Influence their Anxiety
Authors: Ojemaye Luka , Olushola-Ogunrinde Joyce , Hawkins Billy , Cottingham Michael
Published: June 2024

To inform the development of culturally and socially appropriate interventions, this study examined the lived experiences of Black female college athletes (BFCA) and identified sources that increase their vulnerability to anxiety. Black Feminist Thought, with sub-tenets of intersectionality and outsider within status, was used as the theoretical foundation to examine the lives of the BFCA. Using an interpretative phenomenological approach, this qualitative study addressed the question: What sociocultural factors affect anxiety in Black female college athletes? Nine Black female college athletes from an NCAA Division I program agreed to participate in this study. Regarding the sources of anxiety, four themes emerged: regimented schedule (subthemes: lack of freedom, decreased choices, and external locus), forced community (subthemes: isolation and team conflict), emphasis on athletics (subthemes: coaching pressures, training pressures, and academic pressures) and navigating marginalization (subthemes: gender & racial stereotypes and gender & racial inequality). Two unexpected themes also materialized: family support and suggested solutions (subthemes: representation and communication). The findings and analysis were based on the data collected and the theoretical lens. The results suggest the need for culturally appropriate interventions to support this specific college athlete population.

Published: June 2024

As project-based learning (PjBL) has become very popular in education over the past few years, this study conducted a comprehensive meta-analysis to synthesize the effectiveness of PjBL in EFL/ESL writing by examining 11 articles based on databases of Scopus and Google Scholar from 2013 to 2023. The result reveals that PjBL had a significant positive effect size in EFL/ESL writing. Moreover, the effect sizes of some moderating variables were analyzed, including educational levels, sample size, research design, intervention duration, and group size. It was found that the most important moderating variable that affects the effectiveness of PjBL in EFL/ESL writing is intervention duration. The significant overall effect of PjBL on ESL/EFL writing implies the need for educators to consider using PjBL in language teaching and learning. Meanwhile future researchers might consider applying other moderating variables such as research design, instructional strategies, and student characteristics, to identify the best practices for implementing PjBL in ESL/EFL writing.
Problem-solving activity during the foreign language writing process: A proposal for categorisation and visualisation of source use and a new take on fluency in multilingual writing
Authors: Kruse Mari
Published: June 2024

Writing processes constitute a complex interplay of planning, formulation and revision. Ideas take shape through the activation of previous knowledge and, when permitted, also its synthesis with information from sources that help to complement it and resolve doubts and shortcomings arising during writing. The possibility to use external help can be especially useful to those writing in a foreign language, and questions about the nature of the sources consulted can contribute new insights into language processing in the multilingual mind, as well as expand our notion of fluency. While leaving the target text is often considered a distraction, a ‘breakdown’ in fluency, it is, in fact, a part of language processing and text creation.
      This article proposes a novel way to use keylogging data from Inputlog (Leijten and Van Waes 2013) to visualise the crosslinguistic nature of solving language and content problems in L3+ writing: creating process graphs to display the temporal dynamics of different types of sources used. The example data comes from a university-level course on Spanish linguistics, where Spanish was a third or subsequent language for the participants. Evidently, the vast majority of their external activity was language-related and brief, and, interestingly, a great part of it recurs to a lingua franca, English. Some social context and reasoning is offered to explain such an observation.

Live cell microscopy sample preparation (yeast culture) v1
Authors: Zahumensky Jakub , Malinsky Jan
Published: June 2024

In our approach, (cell-walled) cells in thick suspensions are placed on microscopy cover glass and overlaid by a small block of 1% agarose prepared either in buffer or cultivation medium identical to that of the respective cell culture, ensuring a close-to-natural environment. The cover glass is taped to a custom-made microscopy sample holder (Tinkercad file for 3D printing can be downloaded here). In this approach, the cells are immobilized on the cover glass just by mild mechanical forces, which does not induce a cellular stress response, as documented by normal actin structure in C. elegans (Chen and Pan, 2021) and by the absence of stress granules S. cerevisiae cells (Grousl et al., 2015; Vaškovičová et al., 2017). Furthermore, the cells spontaneously prefer a monolayer arrangement, i.e., they are mostly in the same focal plane. This makes microscopy imaging more efficient, saving both time and storage space. Since the agarose is permeable for small molecules, cells can be treated by directly adding chemicals onto the agarose block (in an inverted microscope) during time-lapse experiments (Grossmann et al., 2007; Grousl et al., 2015; Vaškovičová et al., 2017). Adding a cover glass on the other side of the sample holder (Fig. 2) prevents water evaporation and shrinking of the agarose block enabling long time-lapse experiments. The described arrangement thus represents an alternative to both surfaces coated with concanavalin A or poly-L-lysine, and expensive microfluidics systems.

Published: June 2024

The collection of soil nitrous oxide, carbon dioxide, and methane greenhouse gas (GHG) flux measurements utilizing static chamber sampling methodology can be both time and labor intensive. The development of an automated field sampling system would allow for the collection of soil GHG samples from multiple static chamber sites more quickly and efficiently (Arnold et al., 2001). This document describes the material assembly of a modified version of the Chamber Automated Sampling Equipment (FluxCASE) from Davis et al., 2018. This automated GHG case is compatible with existing soil GHG static hoods and requires minimal field training to use. The automated GHG case main components are: one 12-volt marine battery, five solenoid valves with attached syringes, a microcontroller, and an actuator. Estimated materials costs for assembly and building one automated GHG case is approximately $600.00 (2024 dollars).

Whole blood is a simple source of DNA/RNA, however while there are several isolation methods in the literature, they are not capable of isolating pure enough nucleic acid to perform molecular analyses such as PCR. One possible explanation is that a variety of inhibitory substances in blood, such as hemoglobulin, are not eliminated or inactivated during the isolation process. Even in some situations, the mini column becomes plugged with blood, making isolation impossible. This is also true for a variety of commercial kits on the market. As a result, additional steps are required to remove these inhibitor components, which lead to the development of special cumbersome methods or commercial kits designed specifically for blood. We developed a universal mini column DNA/RNA isolation method that can separate DNA/RNA from whole blood without pretreatment or clotting of the small column. The EDTA blood samples or fresh blood samples should be used in this protocol, hence heparin blood samples cannot be used as heparin is known to inhibit the PCR. The extracted nucleic acid is used for performing various molecular assays on biomarkers, viruses, bacteria, fungi, and parasites such as Plasmodium species. This kit is also useful for detecting blood pathogens such as Plasmodium (a malaria parasite), Babesia, Anaplasma, and more. This approach can also be applied to buccal swabs, nasal swabs, tissue, plasma (serum), lymph nodes, and circulating cells. The user does not need to have multiple kits to perform nucleic acid isolation, which saves money and time.

Published: June 2024

The Regional Metrology Laboratory is the lone government institution that provides calibration services in Region IV-A or in CALABARZON. RML's objective is to guarantee the safety and fair trade of both local and international markets by calibrating measuring devices and instruments used by industry and the general public. RML is also ISO/IEC 17025 certified, demonstrating that its calibration services meet the international standard for testing and calibration laboratories. However, the complexity of the preparation of calibration certificates with the increasing number of clienteles becomes the bottleneck and cause of delay in the release of certificates. RML ++ is a system which is a management software solution that optimizes the processing of documentary requirements, from the receipt of customers' measuring devices and instruments to the issuance of calibration certificates. The system was developed using the Model-Driven Architecture (MDA) that is built on the principle of abstraction, modelling reuse, and patterns to help understand standard referencing and all the mathematical calculations of the three (3) calibration certificates namely the Single Range Electronic Balance, Thermohygrometer, and Test Weights. RML ++ was able to reduce the processing time of the calibration certificates from encoding to releasing with a systematic process of the mathematical calculation of uncertainty and selection of standards.

The paper examined the concepts of corporate governance and financial distress. This was achieved by a review of case studies. The review of literature showed that few studies have actually attempted to address the question of whether corporate governance can cure a financially distressed firm. In an attempt to fill this gap, the study this paper examined corporate governance cases of firms that were financially distressed or eventually collapsed. The idea is to be able to take a position as to whether corporate governance can be used as an antidote to financial distress. To achieve this objective, the paper conducted a case study analysis of financial distress cases from different jurisdictions (Multinational, African and Nigerian firms). Documentary evidences on financial distress and challenges of corporate governance were also reviewed. The result of the case study analyses showed that corporate governance can be a cure for financially distressed firms with a condition that key stakeholders in the firm implement the corporate governance provisions.

Literatura iz područja upravljanja prihodima u hotelijerstvu ukazuje na potrebu praćenja cijena konkurenata. Kako bi hoteli ostali konkurentni te ostvarili veće prihode po sobi, potrebno je redovito uzimati u obzir cijene glavnih konkurenata. Ovo istraživanje utvrđuje upravo odnos između cjenovne strategije i ostvarene pozicije hotela u njegovu kompetitivnom setu, mjerena relativno ostvarenom iskorištenosti kapaciteta i prihodom smještaja po raspoloživoj sobi. Cilj je istraživanja utvrditi mogućnosti konkurentskog formiranja cijena u hrvatskom hotelijerstvu te istražiti u kojoj mjeri ono utječe na ostvarene prihode hotela, utvrđujući doprinosi li povećanje ili smanjenje cijena u odnosu na konkurente rastu prihoda smještaja po raspoloživoj sobi (RevPAR-a). Istraživanje je provedeno u petogodišnjem razdoblju (2014. – 2018.), a podaci su preuzeti iz baze podataka Benchmarking hrvatskog hotelijerstva. Po uzoru na prethodna istraživanja (Enz, Canina & van der Rest, 2015), u analizi se primjenjuju metode pokazatelja tržišnog udjela te panel analiza podataka. Dobiveni rezultati naglašavaju značenje cjenovnog pozicioniranja u odnosu na konkurente te njihov potencijalni utjecaj na ostvareni rezultat. Istraživanje pokazuje da hoteli s višim cijenama u odnosu na svoj kompetitivni set ostvaruju nižu razinu iskorištenosti, ali istovremeno viši RevPAR te ukazuje na važnost strateškog cjenovnog pozicioniranja i primjene kompetitivnog formiranja cijena kao važnog instrumenta discipline upravljanja prihodima.

Every business must continue to innovate due to the industry's rapid evolution if it hopes to avoid being disrupted by innovations in the future. The Pos Aja! app, a revolutionary new offering from courier and logistics services provider Pos Indonesia, was introduced in 2020. With Just Post!, consumers can transact from anywhere without physically visiting the post office. Pos Aja! facilitates not just transaction processing for clients but also helps businesses better understand their clientele. The technique known as customer relationship management, or CRM, works to maintain and improve ties between businesses and their clients. Client segmentation is one method of investigating client profiles. Recency, Frequency, and Monetary analysis, or RFM, is the customer segmentation method employed in this study in order to identify the traits of Pos Aja! customers. Three types of Pos Aja! customers—Gold, with 857 clients; Silver, with 566 customers; and Bronze, with 688 customers—were obtained based on the RFM data. The RFM data were then sorted to determine the category of new Pos Aja! clients. The Random Forest, Decision Tree, and Support Vector Machine (SVM) classification techniques are employed. With an accuracy level of 96.69%, the SVM model emerged as the top performer among these three models. Therefore, the SVM model can be applied to determine new client groups.
Addressing the Era of Open Data and Policy Solutions in Indonesia
Authors: Herma Adis  , Catur Apriono
Published: June 2024

Openness of Government Data is considered important and is an innovation that influences from the community to prevent corruption by increasing transparency of information and data. This has been done by almost most of the Ministries / Government Agencies in Indonesia in all aspects that include data disclosure in the social, economic, cultural, political and security fields. One of the drivers of the emergence of Open Government Data (OGD) is the era of the industrial revolution 4.0 which has affected all aspects of life with all technological advances so that people tend to require information disclosure in supporting and overseeing the running of the government. Conversely, the lack of utilisation of OGD is something that the Government really needs to pay attention to. Here the author discusses the openness of government data in Indonesia, with several literature review studies and reviews of several journals and interviews with several experts who are expected to provide recommendations related to the importance of data disclosure using several measurement parameters so that the gap between the framework and the OGD concept itself in Indonesia can be considered. In addition, the final goal of this study aims to provide foresight for policies that can be taken by the Government aimed at data transparency that can be used optimally by the general public and does not conflict with policies that have been implemented on data disclosure information.
