Strategic Change as a Process of Meaning Making : Empirical Studies on Sensemaking, Role Identity, and Accountability Enactment in Situations of Strategic Change
Authors:   , Konuk Vivienne
Published: January 2024

This thesis explores strategic change as a process of meaning making. Most of the literature on strategic change has previously considered organisational actors either as recipients or enactors of change. As strategic change typically acts as a trigger of meaning void, it requires organisational actors to revise their interpretation of organisational reality, all while being engaged in strategizing activities. Arguing that strategic change has to be understood as part received, part enacted when investigating the notion of meaning, this dissertation aims to contribute to the overarching research question of “How do organisational actors respond to ambiguous meanings while enacting strategic change?”. This thesis consists of three empirical papers building on the theoretical lenses of sensemaking, role identity, and accountability. I demonstrate the importance of enactment for organisational actors in order to create new meaning of organisational reality and to be able to prospectively make sense of and commit to strategic change. I further show how the enactment of managerial role identity influences managerial intentions, and thus strategic change. Finally, I demonstrate how middle managers enact accountability and shape their roles in change-related ambiguous environments, which determines their contribution to strategic change. Each paper of this dissertation, each with its own theoretical contributions, demonstrates the simultaneity of change reception and enactment, as strategic change is a process of meaning making.
Matéria e objeto contra forma
Authors: Gasparete Luiz Philip
Published: January 2024

O artigo tem como foco a análise de duas propostas de superação do conceito de forma. Uma é a da pesquisadora e artista Denise Ferreira da Silva, que preconiza uma interpretação de obras de arte fundamentada no trabalho o material em estado bruto, o que resultaria na dita poética feminista negra. A outra é a do pesquisador Sérgio Martins, que apregoa uma maior validade crítica da noção de objeto para abordar criações contemporâneas. O artigo pretende indicar como surgem inconsistências no raciocínio dos dois autores e como, em última análise, a ideia de forma permanece pouco contestada ou até mesmo fortalecida.

Era exibido e folheado nos pavilhões que o Brasil participava nas exposições nacionais e internacionais. Sua execução representou uma importante contribuição das belas artes ao apresentar a exuberância da paisagem brasileira caminhando lado a lado com o progresso representado pela locomotiva.
Frieda Hunziker
Authors: Martinez Felipe Sevilhano
Published: January 2024

Este artigo analisa a obra da pintora holandesa Frieda Hunziker, mais especificamente as pinturas feitas por ela na década de 1950. Este texto foi formulado a partir dos documentos encontrados no Nederlands Instituut voor Kunstgeschiedenis (RKD) e nos arquivos do Stedelijk Museum Schiedam. Neste museu, foi realizada uma exposição sobre artista de abril a setembro de 2023, chamada Vlucht naar Curaçao. A exposição afirma que uma viagem feita por Hunziker a Curaçao, entre 1952 e 1953, foi fundamental para sua produção. Conforme será discutido ao longo do texto, pretendo argumentar que essa importância não foi tão grande quanto a exposição insiste. Também serão explorados aspectos gerais de sua obra, bem como sua participação na Bienal de São Paulo.

Children with respiratory tract disorders often experience an increase in excessive mucus production in their lungs, mucus/phlegm often accumulates and becomes thick making it difficult to be expelled. Management of asthma in children can be carried out pharmacologically and non-pharmacologically. Non-pharmacological therapy can be done in various ways, including effective coughing exercises and deep breathing relaxation techniques.

Methods.  Case study research on one participant (An. A). This research was conducted for three consecutive days in the general hospital in Banyumas with a duration of five minutes for each intervention. Both of these interventions were carried out once a day after being given nebulizer pharmacological therapy.

Results. Intervention of effective cough techniques and deep breathing relaxation techniques has an impact on expelling sputum (phlegm) and can improve respiratory frequency in children.

Conclusion. Practicing effective coughing can reduce symptoms of coughing up phlegm thereby helping to expel sputum while deep breathing relaxation techniques can increase oxygen saturation and decrease respiratory frequency. Both of these non-pharmacological therapies can be carried out well independently.

Fish also has protein with high nutritional value so it can be used as a source of protein to replace meat. Sheet floss is a processed food product made from catfish floss which is square in shape, brownish in color, hard in texture, and has a rough surface. This research was conducted in November-December 2023 on making shredded catfish sheets. To produce a recipe for shredded catfish sheets requires several production trials. The shredded catfish sheet product produced is in small sheets so it is easy to consume. Making shredded catfish sheets begins with making shredded catfish first. then make shredded sheets by baking. Shredded sheets have a brownish color due to the influence of added sugar, resulting in a Maillard reaction which causes a brownish color. slightly brownish in color. Then, the aroma produced by shredded sheets is not fishy because natural spices are used to eliminate the fishy smell. The taste of the shredded sheets is sweet and savory due to the addition of sugar and the use of spices which add a savory taste. The texture of these shredded sheets is rough, crisp and crunchy because the temperature and time when roasting the shredded shreds is controlled.

Published: January 2024

General elections are a crucial pillar of democracy in Indonesia, allowing citizen participation in selecting leaders and shaping policies. Strong criminal law policies are necessary to preserve the integrity of elections, despite challenges in consistent law enforcement and clear definitions of election violations. The aim of this research is to assess the implementation and effectiveness of criminal law policies in preventing and addressing election violations in Indonesia and to identify their impact on the election process. The research findings indicate that the implementation of criminal law policies in preventing and addressing election violations is crucial. This is achieved through stringent election regulations, strict enforcement of criminal sanctions, careful monitoring and investigation, and swift handling of violations. The effectiveness of criminal law policies is also evident in deterring violations, ensuring transparency in funding, and active citizen participation in monitoring. Criminal law policies have a significant impact on the election process. Positive impacts include efforts to prevent election crimes, protect voting rights, and address election law violations through strict regulations. Prevention of election crimes such as spreading false information and the use of violence is tightly regulated to maintain election integrity. Protecting voters' rights is a focal point, with prohibitions against bribery and intimidation practices. However, the negative impact lies in the potential misuse of criminal law for political purposes, which can undermine the principles of presumption of innocence and human rights.

It would have been much better if both speakers and interlocutors could carry out conversations with each other that meet the rules of language when providing information in a communication that was carried out in real life, or it can be said that the communication carried out was communicative. Each response must be pertinent to the question, not wordy, and contain no lies or ambiguous conversations so that the speaker or interlocutor understands more about what was being discussed. As a result, cooperative principles in discourse are required. This study is connected to linguistic rules in the film Extraction II. This study aimed to (1) determine the type of violation of the cooperative maxims presented in the film Extraction II and (2) characterize the speakers’ motivation behind committing the violation. The methodologies and strategies employed in the Extraction II film research were the listening and note-taking methodology for data collection and then the researcher employed a data analysis technique, specifically the equivalent method, to identify the form of violation and motivation of the cooperative principle. In addition, the approach used in this study was qualitative. According to the findings of the research, there were seven violations of the cooperative principle in the film. These infractions included one violation of the maxim of quantity, three maxims of quality, two maxims of relevance, and one maxim of manner. In addition, the violation served six purposes: to convince, plan something, cover something, express annoyance, divert the topic of conversation, and confirm identity.

Published: January 2024

Surface mining, including tin mining, is the most common mining practice in Indonesia. The existence of mining ore or minerals close to the surface soil is the reason for carrying out this mining method. The process of mining surface resulted in the change of land landscape, which may cause soil erosion and even flood. It has caused various ecological and environmental problems, including soil degradation. This study describes soil physio-chemical properties impacted by surface tin mining in Bangka, Indonesia. Soils were collected from three different land use in natural forest, agroforestry, and post tin mining area in Bangka Regency, Province of Bangka Belitung Island. Five-spot soils were sampled from each site. Each site had three replication of the sampling area. The plot size for each site is about 200-500 m2. Soil texture, pH, total N, available P, exchangeable K, organic carbon, C/N ratio, CEC, Al3+, and H+ were analyzed. The results showed that mining decreased organic carbon, total N, available P, exchangeable K, and CEC. Mining changed the soil texture to be dominated by quartz sand. These results indicate that mining significantly deleterious soil fertility, therefore, potential as a limiting factor for plant growth, which could be a hamper for restoration efforts of post tin mining areas.

Program Pengelolaan Sampah 3R Berbasis Masyarakat telah diterapkan di Kota Balikpapan, yakni terdapat di lokasi ITF (Intermediate Transfer Facilities) Kota Hijau Balikpapan. ITF Kota Hijau berperan dalam mengolah sampah organik sebanyak 0,65 ton/hari dengan persentase 0,14% dan lebih dari 73% lainnya dari fasilitas MRF, komposting oleh kawasan publik, dan TPA. Namun dalam penerapannya kegiatan pengolahan persampahan ini menghadapi tantangan lain yakni, meningkatnya emisi gas rumah kaca. Sektor pengelolaan limbah padat merupakan salah satu penghasil gas rumah kaca berupa CH4 dan CO2. Sehingga diperlukan analisis mengenai gas rumah kaca selama pengelolaan sampah dilakukan. Analisis ini dilakukan untuk mengetahui banyaknya emisi gas rumah kaca yang dihasilkan selama sektor pengelolaan sampah berlangsung. Beberapa analisis yangdilakukan dalam penelitian ini diantaranya analisis jumlah sampah yang dikelola, menentukan skenario perhitungan emisi grk, dan menganalisis hasil emisi grk yang didapat. Analisis ini menggunakan metode berdasarkan Intergovernmental Panel on Climate Change (IPCC) 2019. Karena belum adanya data faktor emisi di ITF maka dalam perhitungan emisi gas rumah kaca digunakan metode Tier 1 dengan data aktvitas dan faktor emisi angka default.

Background: The growth of arthroplasty procedures requires innovative strategies to reduce inpatients Length of Stay (LOS). This study aims to develop a machine learning prediction model that may aid to predict LOS after hip or knee arthroplasties. Methods: A collection of all the clinical notes of patients undergoing elective primary or revision arthroplasty from 1 January 2019 to 31 December 2019 was performed. The hospitalization has been classified as “Short LOS” if it was less than or equal to 6 days and “Long LOS” if it was greater than 7 days. Clinical data coming from pre-operative laboratory analysis, vital parameters, demographic characteristics of patients were screened. Final data have been used to train a Logistic Regression model with the aim of predicting short or long LOS. Results: Final dataset was composed of 1517 patients (795 “LONG”, 722 “SHORT”, p = 0.3196) with a total of 1541 admissions (729 “LONG”, 812 “SHORT”, p < 0.000). Complete model had a prediction efficacy of 78,99% (AUC 0.7899). Conclusions: Machine learning may facilitate day-by-day clinical practice predicting which patients are suitable for a shorter LOS, from those with a longer LOS in which a cautious approach could be recommended.

To obtain long-term data on the use of everolimus in patients who underwent liver transplantation for hepatocellular carcinoma, we conducted a retrospective, single-center analysis of adult recipients transplanted between 2013 and 2021. Patients on everolimus-incorporating immunosuppression were matched with those on tacrolimus using an inverse probability of treatment weighting methodology. Two propensity-matched groups of patients were thus compared: 233 (45.6%) receiving everolimus versus 278 (54.4%) on tacrolimus. At a median (interquartile range) follow-up of 4.4 (3.8) years after transplantation, everolimus patients showed a reduced risk of recurrence versus tacrolimus (7.7% versus 16.9%; RR=0.45; P=0.002). At multivariable analysis, microvascular infiltration (HR=1.22; P<0.04) and a higher tumor grading (HR=1.27; P<0.04) were associated with higher recurrence rate while being within Milan criteria at transplant (HR=0.56; P<0.001), a successful pre-transplant downstaging (HR=0.63; P=0.01) and use of everolimus (HR=0.46; P<0.001) had a positive impact on the risk of post-transplant recurrence. EVR patients with earlier drug introduction (30 days; P<0.001), longer treatment duration (P<0.001), and higher drug exposure (5.9ng/mL; P<0.001) showed lower recurrence rates versus TAC. Based on our experience, everolimus provides a reduction of the relative risk of hepatocellular carcinoma recurrence, especially for advanced-stage patients and those with earlier drug administration, higher drug exposure, and longer time on treatment. These data advocate for early everolimus introduction after liver transplantation to reduce the attrition rate consequent to chronic immunosuppression.

A metal-free electrochemical oxidative difluoroethylation of 2-arylbenzimidazoles was accomplished, which provided an efficient strategy for the synthesis of MeCF2-containing benzo[4,5]imidazo[2,1-a]-isoquinolin-6(5H)-ones. In addition, the method also enabled the efficient construction of various difluoroethylated indolo[2,1-a]isoquinolin-6(5H) ones. Notably, this electrochemical synthesis protocol proceeded well under mild conditions without metal catalysts or exogenous additives/oxidants added.

Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are endemic threats to cassava production. To fill the existing gaps in the understanding of the epidemiology of these diseases in Côte d’Ivoire, nationwide field surveys were conducted in 2016, 2017 and 2020. The leaf samples collected were analysed by PCR. CBSD was not detected in all fields visited. However, an increase of CMD incidence was observed from 45.95% in 2016 to 51.37% in 2020 while CMD severity remained moderate over the years with a mean value of 2.29. Low whiteflies number was observed in field and decreasing over the years. Molecular analysis allowed detection of East African cassava mosaic Cameroon virus (EACMCMV) in single as well as in mixed infection with African cassava mosaic virus (ACMV). Single EACMCMV infection, which was detected only in three agroecological zones of the eastern Côte d’Ivoire in 2016, spread throughout the country in 2017 and became more widespread in 2020 with a preponderance in the central and southern zones, whereas the ACMV+EACMCMV coinfection has spread to the entire zones studied. Knowing the dynamics of the evolution of these viruses across the country, better disease management strategies could be adopted to control the disease.
Use of the Investigator ESSplex SE QS Kit (QIAGEN) at half PCR Reaction volumes for
the analysis of forensic samples

Published: January 2024

Background: the Investigator ESSplex SE QS Kit (Qiagen) is a next generation PCR kit that, in 60 minutes, amplifies 17 STRs markers, including the 5 European Standard Set (ESS) loci, the SE33 marker and the locus Amelogenin for sex determination. Two Quality Sensors (QS1 and QS2) are co-amplified to check PCR performance. Since forensic laboratories carry out annually hundreds of DNA typing, we verified the kit performance using half reaction volumes with the aim to improve the number of samples that may amplified with a kit, reducing consequently the laboratory costs.
Methods: in the study, that is intended as a technical note and not an internal validation, were analyzed control samples (oral swabs) with known DNA profiles and 40 real caseworks samples.
Results: we observed that reducing the total reaction volume, while keeping unaltered all components ratio’s, yields DNA profiles comparable to the ones obtained using standard reaction volumes and with alleles peaks higher than with standard volumes..
Conclusions: the use of half volumes for PCR amplification allows the analysis of a wider number of samples than the standard protocol, reducing laboratory costs while maintaining unaltered the quality level of the analysis.

Static and functional occlusal relationships are the well-defined objectives of orthodontic therapy. To accomplish it, the jaws must be positioned in centric relation (CR)/ Central occlusion (CO) and appropriately proportioned in three space planes. Orthodontists have well-established techniques when analyzing the skeletal connection between the maxilla and mandible in both sagittal and vertical planes. Although there exist multiple analyses for the skeletal transverse dimension (STD), their inclusion in conventional orthodontic diagnosis is not widely acknowledged. Transverse tooth compensations have been visually represented in prosthodontic literature using a crosshatch arch that passes through the buccal and palatal cusps of maxillary molars, known as the Wilson curve. An inflated Wilson curve has long been seen as a prosthetic maxim, increasing the possibility of working and non-working side interferences. Research has indicated a connection between higher masticatory muscle activity and posterior occlusal contacts or interferences. When skeletal transverse issues are concealed by dental expansion, there is an elevated susceptibility to gingival recession in orthodontic patients who have a small Maxilla or constricted upper jaw. The temporomandibular joints, muscles, periodontal tissue, and airway might all suffer in a susceptible patient with a transverse insufficiency brought on by a narrow maxilla. As for orthodontists, the objective is to create skeletal connections and functional occlusion that are as near ideal as feasible. This will reduce the likelihood of occlusion-related inconsistencies exacerbating the negative consequences on the dentition, periodontium, or joints. An accurate skeletal and dental diagnostic in all three space planes is required. Our goal is to explain all approaches to enable readers to use a transverse skeletal diagnostic in their practice regardless of the technological level at their disposal. The initial step is to ascertain the kind and presence of deficiencies in the maxilla. Since fewer soft tissue alterations are caused by maxilla hypoplasia in the transverse direction, skeletal transverse dimension (STD) assessment is a more significant challenge than vertical or sagittal discrepancy assessment. Model analysis, clinical assessments, radiographic measurements, and occlusograms have all proven successful in producing accurate assessments. Most of the time, surgically assisted maxillary expansion (SARME) is reported to have higher stability than orthopedic maxillary expansion (OME). We examine and discourse on possible research opportunities using the Collaborative Cross (CC) mouse model as a substitute research model.

Published: January 2024

The algorithmic complexity vulnerability (ACV) that may lead to denial of service attacks greatly disrupts the security and availability of applications, and due to the widespread use of third-party libraries, its impact may be amplified through the software supply chain. The existing work in the field is dedicated to abstract loop or iterative patterns and fuzzing the entire application to discover algorithm complexity vulnerabilities, but they still face efficiency and effectiveness issues. Our research focuses on: (1) Proposing a representation and extraction method for code features related to algorithmic complexity vulnerabilities, helping analysts quickly understand program logic; (2) Providing a new ACV detecting model, focusing on the spatial complexity anomalies caused by deep recursion structures, and proposing a new filtering method; (3) Aiming at the difficulty of efficiently generating complex-data-type-related payloads using existing symbol execution techniques, a call-chain-guided payload construction method is proposed. We tested third-party components in the open-source Java Maven Repository, identified many unexposed vulnerabilities and 8 of them received CVE (Common Vulnerabilities & Exposures) identifiers, and demonstrated that our method can discover more algorithmic complexity vulnerabilities compared to existing tools with better performance.
