An Indigenous embodiment of Conduction: Collective composition for traditional Māori instruments and beyond
Authors: Gooch Riki
Published: March 2024

This article looks at the indigenization of Butch Morris’s Conduction methodology by embodying it within ngā taonga puoro (traditional Māori musical instruments and practice). It explains the transition of Conduction from western music ensembles to a Māori instrumental orchestra. This is an examination of how the alteration of Morris’s conducting vocabulary can offer an alternative to the challenges faced with writing for ngā taonga pūoro within the context of western musical notation and how the recording process contributed to this development.

Accessing marginalized musics through adaptable, culturally sustaining music technology modules
Authors: Adu-Gilmore Leila
Published: March 2024

Black music technology has innovated across genres such as dub, hip hop, techno and Afrobeats, redefining music as we know it. Music research subfields (performance, composition, musicology, technology) have historically excluded black musics but music education has begun to include them. Critical Sonic Practice Lab created a culturally-sustaining music technology toolkit and modules in Accra, Ghana. We exploit music technology’s constant evolution, engaging critical sonic practice’s intersectional approaches to the continuum of improvisation and composition, and music theory. Adjusting teaching resources for students with less finances and internet access can give access to STEAM (science, technology, arts and mathematics) and music creation. We recenter Black, Latinx and Indigenous musics and participatory music practices to expand music creation. Therefore, this research design offers a series of decolonizing music technology and creation prompts to adapt with local music practitioners as teaching-artists for community-specific teaching and learning.
Why aren’t the straight people laughing? Camp reluctance and the therapeutic reflex
Authors: Harris W. C.
Published: March 2024

Amidst heightened mainstreaming, are there factors that dampen camp enjoyment or engagement for fairly receptive, more or less camp-versed audiences? Even viewers responsive to camp subculture can be susceptible to a tendentious, contrary impulse: prescriptive sobriety regarding heteronormative totems, rituals and topics that a prevailing model of medicalized subjectivity enjoins one to take seriously by default. Building on established queer interventions in camp studies, this article proposes the term ‘therapeutic reflex’ for this normative, mockery-reluctant influence – distinct from heteronormativity but frequently collaborating with it. In wilfully camp fashion, this article looks at five mid-century American films – Now, Voyager (1942), Strangers on a Train (1951), The Bad Seed (1956), Suddenly, Last Summer (1959) and Psycho (1960) – as specimens of camp resignification’s knack for exposing lingering therapeutic bias, its paradigm of subcultural conservancy and its affordance of normative scrutiny and counternormative dissidence.

Teorías y prácticas educativas contrahegemónicas. Sobre la pedagogía disruptiva
Authors: González-Alba Blas , Mañas-Olmo Moisés , Prados-Megías María Esther , Sánchez-Sánchez María
Published: March 2024

El concepto disrupción pedagógica se ha relacionado durante años con la innovación pedagógica, la ruptura con modelos educativos tradicionales, el uso de las TIC y la búsqueda de la calidad educativa; aun así, dicho concepto, desde un sentido práctico, está poco definido, por lo que sigue siendo elemento de estudio, más aún cuando nos referimos a la enseñanza secundaria. En esta investigación presentamos y analizamos 47 prácticas pedagógicas desarrolladas en centros educativos de secundaria tanto de ámbito nacional como internacional que responden a los principios de las pedagogías disruptivas. Se desarrolla una revisión sistemática de la literatura considerando la información recogida en diferentes bases de datos (Scopus, Web of Science, ERIC, Catálogo Jábega, Dialnet). Los resultados muestran, por un lado, que la disrupción pedagógica puede utilizarse como una valiosa herramienta para mejorar aspectos sobre la calidad de la educación tradicional, especialmente en contextos donde se requiere una transformación social. Por otro lado, aporta un conjunto de estrategias con las que el alumnado se siente más motivado y comprometido con su aprendizaje a la par que le permite obtener mejores resultados académicos.
Exploring the relevance of sustainability values and principles - impact of International Social Education (ISE) in a local context
Authors: Thönnessen Joachim , Christensen Jonas
Published: March 2024

This article explores the relevance of sustainability in international social education (ISE). Our empirical data is based on a survey of social work students from Switzerland, Austria, Germany and Sweden. Theoretically, we draw on Bronfenbrenner’s theory of social ecosystems and Dewey’s emphasis on democratic learning. We use a qualitative approach based on Strauss’ Grounded Theory, which allows us to dig deep into the meanings of the students thematic reflections. The students experienced that learning in an international context is learning with all senses, is a “24/7 learning”, and is learning in another language (at least most of the time). The results of our survey underline that acquiring knowledge in an international context contributes to a comprehensive understanding of social work as a profession and to the formation of a broad and professional identity. This includes a wide range of critical and systemic thinking skills that enable enquiry, integration and holistic thinking, i.e. sustainability.
Pengaruh pendekatan faded example secara kolaboratif terhadap kemampuan pemecahan masalah dan cognitive load
Authors: Borahima Dea Qurrotaa'yun Putri Maharani , Endah Retnowati
Published: March 2024

Kemampuan pemecahan masalah sebagai salah satu tujuan pembelajaran matematika yang menjadi perhatian para guru karena memfasilitasi siswa untuk lancar dalam memecahkan masalah memerlukan strategi tertentu. Sementara itu, pembelajaran matematika juga bertujuan memfasilitasi siswa untuk berinteraksi dengan siswa lain dalam pembelajaran kolaboratif. Penelitian ini bertujuan untuk menguji apakah strategi pembelajaran faded example dapat diterapkan dalam pembelajaran kolaboratif, khususnya untuk materi dengan tingkat intrinsic cognitive load relatif rendah. Di dalam desain faded example, siswa belajar dengan melengkapi langkah-langkah pemecahan masalah secara bertahap. Di dalam desain problem solving only, siswa hanya diberi masalah matematika untuk dipecahkan tanpa ada stimulasi langkah-langkah pemecahan tertentu. Melalui randomisasi individu beserta eksperimen desain faktorial 2 x 2, terbentuk empat kelompok yaitu: siswa dengan strategi pembelajaran (1) faded example secara kolaboratif, (2) faded example secara individu, (3) problem solving secara kolaboratif, dan (4) problem solving secara individu. Dengan Analysis of Variance (ANOVA), hasil penelitian menunjukkan bahwa strategi pembelajaran dalam desain faded example atau problem solving sama efektifnya dalam hal memfasilitasi penguasaan kemampuan pemecahan masalah, dan juga menghasilkan tingkat cognitive yang sama; baik ketika dipelajari secara kolaboratif maupun individu. Penelitian ini menyimpulkan bahwa apabila materi pemecahan masalah memuat kompleksitas yang rendah, guru dapat memilih menggunakan desain faded example sebagai alternatif desain problem solving. Guru juga dapat memilih strategi kolaboratif karena hasil kemampuan yang dicapai pun tidak lebih rendah jika menggunakan strategi individu.

Authors: Almaghfiroh Violina , Afandy Muhammad Irfan , Marhayati Marhayati
Published: March 2024

Students' interest in learning mathematics in Indonesia still needs to be improved. Efforts can be made by providing creative learning in the classroom, one of which is by linking mathematics and culture, known as ethnomathematics. Ethnomathematics can be used as a learning innovation to motivate students to learn mathematics. Therefore, this study aims to explore the concept of mathematics in one of the traditional game cultures still developing in Malang, East Java, namely Gaple. Gaple cards can be used as a media for learning mathematics in set material linked through the Realistic Mathematics Education (RME) approach. This study used a descriptive qualitative method with an ethnographic approach, which describes the results of the ethnomathematics exploration of the Gaple card game. Data collection uses observation, interviews, literature review, and photo documentation to explore ethnomathematics elements on gaple game cards. Exploration results were obtained by observing the number of points on each gaple card, namely the concept of universal sets, intersections, unions, and complements. These results are then packaged in a table of learning activities by implementing the three stages of the RME approach.
Apakah pembelajaran diferensiasi mengakibatkan cognitive load tinggi?
Authors: Aini Rosita Nurul , Retnowati Endah
Published: March 2024

Cognitive load theory menjelaskan pentingnya analisis kemampuan awal siswa dalam desain pembelajaran karena perbedaan kemampuan awal mengindikasikan perbedaan tingkat cognitive load yang dialami selama kegiatan pemecahan masalah. Adanya diferensiasi metode pembelajaran diduga lebih efektif sebagai pendekatan pembelajaran berdasarkan divergenitas tingkat kemampuan awal siswa. Penelitian ini bertujuan untuk menguji apakah terdapat perbedaan efektivitas pembelajaran statistika  dengan metode diferensiasi dan pembelajaran non-diferensiasi ditinjau dari kemampuan pemecahan masalah dan cognitive load siswa. Metode diferensiasi yang dikembangkan adalah dengan memberikan metode pembelajaran sesuai kategori tingkat kemampuan awal, yaitu jika rendah (metode worked example), sedang (metode faded example), dan tinggi (metode problem solving block). Penelitian quasi experiment dengan desain penelitian posttest only grup design ini melibatkan 60 siswa (novice) kelas VIII SMP dalam pembelajaran statistika berorientasi kemampuan pemecahan masalah.  Menggunakan uji ANCOVA dengan nilai pretest sebagai variabel kovariat diperoleh bahwa pembelajaran diferensiasi sama efektifnya dengan pembelajaran non-diferensiasi ditinjau dari pencapaian kemampuan pemecahan masalah. Namun, pembelajaran diferensiasi dapat menurunkan cognitive load siswa selama kegiatan pembelajaran.

Demands, tensions, and resources when implementing ambitious mathematics
Authors: Choppin Jeffrey , Green Christine , Zahner William
Published: March 2024

In this article, we explore demands and tensions involved when schools implement ambitious mathematics teaching (AMT). Following a description of a framework that distinguishes between internal and external demands, we characterize the tension between these in terms of alignment, balance, and buffering, which collectively speak to coherence. We then describe AMT and how it represents a departure from traditional mathematics instruction found in most countries. We applied the framework to an illustrative case and found that while the school devoted considerable resources to reforming mathematics teaching and learning, challenges persisted. These challenges include ongoing language and participatory demands for students and, for teachers, balancing the demands of implementing AMT with a range of other initiatives. The framework provides a means of exploring the full range of demands associated with ambitious instructional reforms, how these demands are mitigated or exacerbated, and the kinds of resources necessary to sustain AMT.
The transformation of social work in Ukraine before and during the war
Authors: Romaniuk Jaroslaw R. , Mamzer Hanna , Farkas Kathleen J.
Published: March 2024

Background: This article aims to review the development of the social work profession in Ukraine and to describe the impact of social, economic and political changes on social work practices and education. Methods: A comprehensive literature review and participant observation methods informed this study. A case study of a Polish community’s response to Ukrainian war refugees illustrates how social workers might capitalize on current social structures to continue strengthening civil society in Ukraine. Findings and Discussion: Social Work, focusing on the fit between person and environment, is shaped by knowledge, culture and belief systems. Ukraine’s history and transition from communist/centralized thinking to civil society is reflected in the development of social work to date. The impact of Russian invasions has hindered and strengthened how social workers can recognize and respond to needs. Limitations include the time lag between published articles and the rapidly changing situation in Ukraine. Originality/Value: Few articles focus on social work development in Ukraine, which adds to this article’s originality and relevance.
Economic, infrastructural and psychological challenges faced by the students of Assam: a study during COVID-19 pandemic
Authors: Saikia Mrinal , Das Prakash
Published: March 2024

A pandemic like the COVID-19 has caught everyone off-guard. The economy is in tatters, and the loopholes in the system are getting exposed. The education sector is no exception, especially in a developing country like India. With millions of students in India, the lockdown will have many unforeseen impacts. Moreover, the parents would be reluctant to send their wards to study even after the pandemic, and the actual effect of a lag in learning would be visible only in the long run. The necessity of e-learning in academia was felt only when the pandemic hit. The lack of ICT infrastructure and the absence of tech-savvy teachers have made studies an absolute roller-coaster ride for students. Apart from this, the already existing disparity between students from different economic strata would very likely broaden. Homebound is another factor affecting the students’ psychology towards study. This paper ventures into the problems faced by the students, especially from economic, infrastructural and psychological factors, ranging from primary to University level. It also attempts to segregate the students based on location and financial condition and understand the specific hindrances they face. Case studies from various locations of Assam provide a cluster of stories that would act as an index in developing the system when time is ‘conducive’.
Heritage language identity matters: Tracing the trajectory of a Chinese heritage mother and contested Chinese dual language bilingual education
Authors: Lee Vashti Wai Yu , Her Lee , De Costa Peter I.
Published: March 2024

This article presents a narrative inquiry of a Chinese heritage mother to theorize and explicate how historical, relational, and spatial processes impacted her negotiation with power and agency in relation to her own heritage language (HL) identity development. A narrative approach enables us to draw on participant counter-stories against master narratives that erase experiences of marginalization of Asians in Asian language education in the United States. We do this through a model of HL identity development (Zhou & Liu, 2022) supplemented by an AsianCrit lens (Iftikar & Museus, 2018). We show the importance of normalizing Chinese as a HL outside of the home in terms of language maintenance as well as the impact such normalization has on the development of an affirmative Chinese HL identity. We add that spaces for such identity development are deeply associated with language programs like dual language bilingual education (DLBE), especially as the number of DLBE opportunities grow in number and in popularity. Thus, language programs, including DLBE, have a responsibility to ensure that the language education they provide address the interests and investments of families with respect to their HL in order to decenter a primary focus on the interests of ethnolinguistic majoritized families.
The role of critical experiences, positioning, and agency in the dynamic, emergent construction of heritage speaker selves
Authors: Serafini Ellen J. , Roca-Ramirez Sara I.
Published: March 2024

Previous research has proposed a crucial role for critical experiences in language learning to better understand how learners understand and discursively construct their self-concept (Mercer, 2011, 2016; Serafini, 2020a; Thompson, 2020). However, studies have mainly explored critical experiences in the narratives of foreign language learners of English with little attention to how heritage speakers of languages other than English (LOTE) draw on critical experiences in discursive constructions of self. To address this gap, this study aims to explore the impact of critical experiences in university heritage Spanish speakers’ self-narratives. Twenty heritage Spanish students completed a background questionnaire and peer-facilitated, video-recorded interview. Emergent, recurring themes were identified in transcribed interview data following tenets of grounded theory (Charmaz, 2006; Glaser & Strauss, 1967). Findings underscore the key role of positioning (Davies & Harré, 1990) in dynamic conceptions of self, particularly how heritage speakers (re)imagine and discursively construct past, current, and future self-states. Positioning was also linked to agency (Ahearn, 2001) in relation to students’ critical reflections on experiences of racialization and resistance to, or reproduction of, dominant language ideologies. Overall, the study provides valuable insights for (heritage) language educators seeking to enact critical pedagogical principles in their classroom and curriculum.
Reexamination of Aspergillus cristatus phylogeny in dark tea: Characteristics of the mitochondrial genome
Authors: Zhiyuan Hu , Lin Chen , Yihan Wang , Meng Dong , Yanzi Li , Zhenggang Xu
Published: March 2024

To enhance our understanding of Aspergillus cristatus, an important functional microorganism, the characteristics of its mitochondrial genome were analyzed and compared with related species. The mitochondrial genome of A. cristatus was determined to be 77,649 bp in length, with 15 protein-coding regions. Notably, its length surpassed that of the other species, primarily attributable to the intron length. Gene order exhibited significant variations, with greater conservation observed in the genus Penicillium compared to Aspergillus. Phylogenetic tree analyses indicated that the genera Aspergillus and Penicillium are closely related but monophyletic. Furthermore, the phylogenetic tree constructed based on protein-coding genes effectively distinguished all strains with high branching confidence. This approach provides a robust reflection of the evolutionary relationship between A. cristatus and its related species, offering potential for the development of molecular markers suitable for Aspergillus and Penicillium.

Previous study on the chip reflective gain variations versus SOA current under temperature effects is clarified. We have transferred light semiconductor amplifiers for wavelength multiplexing schemes applications. Amplifier output power is demonstrated with bias current and amplifier active layer region length variations based input signal power of 3, 6.5, 10 dBm, 1550 nm wavelength and optimum amplifier confinement factor of 0.45. The amplifier output noise variations are clarified against the bias current and amplifier active layer region width variations based input signal power of 3, 6.5, 10 dBm, 1550 nm wavelength and optimum amplifier confinement factor of 0.45. The output OSNR variations are studied clearly and deeply against the bias current and amplifier active layer region length variations based input signal power of 3, 6.5, 10 dBm, 1550 nm wavelength and optimum amplifier confinement factor of 0.45. The signal loss is demonstrated versus both active layer width/length and temperature based optimum 30 % gallium core dopant ratio and 28 % arsenide cladding dopant ratio at optimum input signal power of 10 dBm, 1550 nm wavelength and optimum amplifier confinement factor of 0.45. SOA amplifier output power can be enhance with the management of both bias current and input signal power and the reduction of active amplifier length. The amplifier output noise can be enhance with the management of both bias current and input signal power and the reduction of active amplifier width. Output OSNR system can be improved with the management of both bias current and input signal power and the reduction of active amplifier length. The SOA amplifier gain can be improved with the management of both bias current and input signal power and the reduction of active amplifier length. The SOA amplifier noise figure can be improved with the management of both bias current and input signal power and the reduction of active amplifier width. The signal loss can be controlled and managed by adjusting optimum 30 % gallium core dopant ratio and 28 % arsenide cladding dopant ratio, optimum active layer/with and the presence of room temperature.
Crucial role of the internalisation of the distinction between dependent and independent variables for clearer chemistry understanding
Authors: Mammino Liliana
Published: March 2024

Mathematics constitutes a fundamental key for the description and understanding of many phenomena. The chemistry discourse incorporates mathematics in various ways and instances. At educational level, interchanges occur in two directions: mathematics provides support for clearer understanding of chemical phenomena, and the level at which students use the relevant mathematics is an indication of the clarity of their conceptual understanding in chemistry. The present work focuses on an issue for which mathematics tightly links to the conceptual understanding of physical terms – the issue of independent and dependent variables. The definition is in principle well known. On the other hand, the distinction between the two types of variables and their roles is not always clearly underlined at explanation level, and is often not sufficiently internalised by students. This results in a variety of misunderstandings and errors. Careful analysis of students’ works enables the identification of errors that can be tracked down to unclear distinction between the dependent and independent variables in a given context; such errors appear in several areas of chemistry, at both undergraduate and postgraduate levels. The present work considers and analyses a number of representative examples, highlighting the impact of their unclear distinction and the ensuing importance of devoting specific attention to it. Selected addressing approaches from direct experience are included and their outcomes discussed.
Methylene blue and its potential in the treatment of traumatic brain injury, brain ischemia, and Alzheimer’s disease
Authors: Isaev Nickolay K. , Genrikhs Elizaveta E. , Stelmashook Elena V.
Published: March 2024

Traumatic brain injury (TBI) and brain ischemia/reperfusion cause neurodegenerative processes that can continue after the acute stage with the development of severe brain atrophy with dementia. In this case, the long-term neurodegeneration of the brain is similar to the neurodegeneration characteristic of Alzheimer’s disease (AD) and is associated with the accumulation of beta amyloid and tau protein. In the pathogenesis of AD as well as in the pathogenesis of cerebral ischemia and TBI oxidative stress, progressive inflammation, glial activation, blood–brain barrier dysfunction, and excessive activation of autophagy are involved, which implies the presence of many targets that can be affected by neuroprotectors. That is, multivariate cascades of nerve tissue damage represent many potential targets for therapeutic interventions. One of such substances that can be used in multi-purpose therapeutic strategies is methylene blue (MB). This drug can have an antiapoptotic and anti-inflammatory effect, activate autophagy, inhibit the aggregation of proteins with an irregular shape, inhibit NO synthase, and bypass impaired electron transfer in the respiratory chain of mitochondria. MB is a well-described treatment for methemoglobinemia, malaria, and encephalopathy caused by ifosfamide. In recent years, this drug has attracted great interest as a potential treatment for a number of neurodegenerative disorders, including the effects of TBI, ischemia, and AD.

Published: March 2024

Due to the noteworthy prevalence of inflammatory periodontal diseases among the population, especially in older age groups, the problem of providing timely and quality care to prevent severe complications leading to tooth loss becomes urgent. Conventional approaches to treatment are not always successful and do not necessarily provide a lasting effect. Therefore, predicting the outcome of the disease is a critical task. Material and Methods — We performed examination of 169 individuals and treatment of 126 patients aged 45-75 years with mild to moderate localized periodontitis of traumatic etiology (LPT) were performed. We employed clinical, radiological, and functional methods of examining periodontal condition, and investigated laboratory blood parameters (complete blood count, C-reactive protein). To assess the body’s adaptive resources, the entropy of the leukocyte blood count was calculated, and risk factors for the occurrence of LPT were assessed. Predicting the course of LPT based on changes in clinical and radiological indicators was accomplished by assessing treatment outcomes and calculating a prognostic score. Results — Patients exhibited a noteworthy prevalence of somatic pathology, with cardiovascular diseases (RR=2.32), anemia (RR=2.26), and gastrointestinal tract disorders (RR=1.88) emerging as predominant conditions (p<0.001). The duration of the disease exceeding three years was associated with a 2.06-fold increase in the risk of developing moderate-grade LPT (p=0.017). With a concentration of C-reactive protein in the range of 3-10 mg/L, the risk of developing moderate-grade LPT increased 1.74-fold (RR=1.74; p=0.0022). The intense type of adaptive reaction of the body was detected in 30.4% and 50.7% of cases with mild and moderate grades of LPT, respectively, increasing the risk of a more severe grade by 1.8 times (p=0.0026). Pronounced local changes in the bone tissue of the alveolar process were observed 1.6-2 times more often in cases of moderate periodontitis vs. mild LPT (p=0.0035). Microcirculation in the inflammation zone decreased by 32% and 50.1% with mild and moderate grade of the disease, respectively (p<0.001). Splinting of teeth in the area of the pathological focus during treatment led to improved clinical indicators vs. the control group (p=0.012). Conclusion — Based on the study results, the prognosis for the course of LPT was most significantly influenced by the following factors: the concentration of C-reactive protein, the grade of LPT, the entropy of the leukocyte blood count, changes in the alveolar bone of the jaw, the duration of the disease, the history of previous periodontal treatment, and tooth splinting. Calculation of a prognostic score for the treatment outcome of LPT allows to qualitatively assess the clinical situation and identify a group at risk of an adverse treatment outcome.

Published: March 2024

This paper investigates the rights of children born into interfaith marriages, focusing on child registration in Semarang. In a multicultural society like Indonesia, children from interfaith unions face complex legal and social challenges. This study explores the nuances of child registration in Semarang, addressing the legal framework, social dynamics, and implications for children's rights. Beginning with an overview of Indonesia's legal context, the paper emphasizes the importance of civil registration in establishing a child's legal identity and access to rights and services. It examines the hurdles encountered by interfaith families in navigating registration procedures, including issues of parental consent, religious affiliation, and administrative barriers. The study also delves into the social aspects of child registration in Semarang, analyzing how cultural norms, religious beliefs, and community attitudes shape the registration process and affect children's legal recognition. Challenges such as social stigma, discrimination, and bureaucratic inefficiencies are highlighted as obstacles to obtaining birth certificates and official documentation for children from interfaith backgrounds. Furthermore, the paper discusses the implications of insufficient child registration for children's rights, emphasizing the importance of equal treatment and legal recognition for all children, regardless of their parents' religious affiliations or cultural backgrounds. By examining the child registration case in Semarang, Indonesia, this study contributes to broader discussions on the rights of children from interfaith marriages and advocates for inclusive policies and practices. Addressing legal and social barriers to registration and promoting interfaith dialogue can ensure that every child enjoys their fundamental rights and opportunities for a fulfilling future.

To find out and analyze the legal consequences in the Minister of Environment Regulation Number 7 of 2014 on the enforcement of environmental criminal law in Indonesia. Additional penalties as in Article 119 UUPPLH do not have detailed implementing rules regarding the mechanism of its application. PERMEN-LH Number 7 of 2014 which is often used by law enforcement officials in environmental cases has weaknesses such as: not in sync with Article 119 of Law Number 32 of 2009 concerning Environmental Protection and Management; there is an overlap of authority between the Ministry of Finance and the Ministry of Environment and Forestry in terms of environmental restoration; and lack of certainty in calculating the extent of the affected area due to criminal acts. The imposition of additional penalties in the form of repairs due to criminal acts that are converted into a sum of money in Decision Number 256 / Pid.sus / PN Rgt; Case Number: 37 / Pid.Sus-LH / 2018 / PN; Case Number 349 / PID.B-LH / 2019 / PN.Plw has not been able to provide protection for the environment because it is considered non-tax state revenue (PNBP), which is entirely deposited into the State Treasury, thus the funds cannot be used as restoration or environmental improvement funds

Cases of this nature underscore the significance of safeguarding personal data and enforcing stringent legal measures. This research employs a normative juridical legal study that integrates two primary approaches: the legislative approach and the comparative approach. The research data sources comprise primary, secondary, and tertiary legal materials obtained through a comprehensive literature review. The data analysis process is conducted using a descriptive method and applying deductive logic. The growth of e-commerce users in Indonesia has witnessed a significant increase. Law Number 27 of 2022 regulates the principles of personal data protection, encompassing the rights of data owners, transparency, and meticulous data management.

Published: March 2024

Günümüzde bilgi teknolojilerinin yaygınlaşması ve markalar arası rekabet bilgi odaklı ve sürekli değişen bir tüketici profilinin ortaya çıkmasına yol açmıştır. Yeni tüketiciler değişen beklentileriyle, marka tercihlerinde somut değerlere ek olarak soyut değerleri de önemsemeye başlamışlardır. Markalar da tüketicilerin beklentilerini karşılayarak olumlu desteklerini alabilmek ve sürdülebilir, güçlü ilişkiler kurmak için toplum yararına olan faaliyetlere yönelmişlerdir. Literatürde kurumsal sosyal sorumluluk kavramı olarak karşılaşılan bu faaliyetlerin pazarlama stratejisi olarak kullanılmaya başlandığı söylenebilir. İlgili literatür incelendiğinde kurumsal sosyal sorumluluk faaliyetlerinin tüketici marka ilişkilerinde kritik bir rol oynadığı ve tüketicilerin markalara karşı bilişsel, davranışsal ve duygusal tepkilerini olumlu yönde etkilediği görülmektedir. Bu bağlamda, bu çalışma kurumsal sosyal sorumluluk algısının, yeni bir kavram olarak literatürde yerini alan marka vefasına etkisini ve bu etkide marka aşkının aracılık rolünü ortaya koymayı amaçlamaktadır. Çalışmada e-ticaret markalarından alışveriş yapan 509 nihai tüketiciden toplanan veriler Smart PLS programı kullanılarak değerlendirilmiştir. Yapılan analizler sonucunda kurumsal sosyal sorumluluk algısının marka vefası üzerinde anlamlı olarak etkili olduğu ve bu ilişkide marka aşkının kısmi aracılık rolü olduğu belirlenmiştir.

Published: March 2024

İnternetin yaygınlaşması ve sosyal medya kullanımının yoğun kullanımı ile tüketiciler, kullandıkları ürünler gibi otel, restoran gibi hizmet ürünleri hakkındaki deneyimlerini sosyal medya yoluyla veya web sitelerinin yorum kısımlarından paylaşabilmektedir. Son yıllarda internette giderek artan müşteri yorumlarının analizi araştırmacılar ve işletmeler için önemli bir kaynak haline dönüştüğü görülmektedir. Zamanla biriken platformlardaki alemdeki bu izler; veri kazıma yöntemleri ile toplanarak Metin Madenciliği, Makine Öğrenmesi ve Duygu analizi gibi yöntemlerle incelenmektedir. Farklı sektörlere uygulanabilen bu yöntemler ile elde edilen sonuçlar, müşteri memnuniyetini göz ardı etmeyen işletmeler için operasyonel, taktik ve stratejik düzeyde karar almalarına yardımcı olmaktadır. Bu kapsamda çalışmada Antalya’daki otellere ilişkin onaylanmış kullanıcıların internet ortamındaki Türkçe olarak yazdıkları yorumlar veri kazıma yöntemleri ile derlenerek, sınıflandırmakta ve duygu analizi ile incelenmiştir. Bu sayede müşteri yorumlarının analizi ile otel hizmetlerinin ve tesislerinin iyileştirilmesine ve dolayısıyla müşteri memnuniyetinin artırılmasına yönelik önemli bilgiler elde edilmesi amaçlanmıştır. Veri seti öncelikle makine öğrenmesi temelli sınıflandırma yaklaşımları ile çevre ile alakalı olup olmamasına bağlı olarak iki gruba ayrılmıştır. Sonrasında veri seti üzerinde duygu analizi yapılarak, elde edilen bulgular ile müşterilerin oteller ile ilgili çevresel algıları değerlendirilmiştir. Bu çalışma, müşteri geri bildirimlerini değerlendirerek işletme stratejilerinin geliştirilmesinde otel yöneticileri için örnek niteliğindedir. Aynı zamanda, metin madenciliği ve duygu analizi yöntemlerinin araştırmacılar tarafından nasıl kullanılabileceği konusunda değerli bilgiler sunmaktadır. Çalışma sonucunda Antalya otelleri hakkındaki 180.478 yorum analiz edilerek, müşterilerin çevreci unsurlara ilgisinin arttığı ve otel seçiminde önemli rol oynamaya başladı bulgusuna varılmıştır. Çevreci faaliyetleri ön plana çıkaran otellerin, daha yüksek müşteri memnuniyetine sahip olduğu, düşük puanlı otellerde çevreci yorumlar daha fazla ve genelde olumsuzken, yüksek puanlı otellerde daha dengeli olduğu gözlemlenmiştir. Çalışma ile otellerin müşteri memnuniyeti için çevreci faaliyetlere önem vermesi önerilmiştir.

Published: March 2024

Viele Daten für Wohnungsmärkte stehen nur zeitverzögert oder gar nicht zur Verfügung. In dieser Studie wird untersucht, ob eine Analyse von Zeitungsnachrichten dazu beitragen kann, die Transparenz auf Wohnungsmärkten zu erhöhen. Hierzu werden Methoden der Computerlinguistik auf rund 320.000 Nachrichtenartikeln zweier deutscher Immobiliennachrichtenanbieter angewendet. Die nachrichtenbasierten Stimmungsindikatoren erweisen sich als zuverlässige Erklärungsgrößen für die Wohnungspreisdynamik.
Die Rolle von Multistakeholderinitiativen im Rahmen der Global Governance: Relevanz, Herausforderungen und kritische Analyse
Authors: Gilbert Dirk Ulrich
Published: March 2024

Im Rahmen der Bemühungen, auf internationaler Ebene ein System der Global Governance zu etablieren, spielen Multistakeholderinitiativen (MSIs) eine wichtige Rolle. MSIs sind freiwillige, sich selbst regulierende und häufig sektorübergreifende Zusammenschlüsse verschiedener öffentlicher, zivilgesellschaftlicher und privater Akteure (z.B. Unternehmen, Gewerkschaften, Regierungen oder NGOs), um bestimmte menschenrechtliche, soziale und/oder ökologische Ziele in kooperativer Weise zu erreichen. In diesem Beitrag geht es insbesondere um MSIs, in denen sich multinationale Unternehmen engagieren, um ihre menschenrechtlichen, sozialen und ökologischen Ziele zu erreichen und so einen Beitrag zur nachhaltigen Entwicklung und zur Erreichung der Sustainable Development Goals zu leisten. Neben den wesentlichen Merkmalen und einer Typologie von MSIs werden verschiedene Beispiele vorgestellt. Zum Abschluss erfolgt eine kritische Analyse der positiven Beiträge von MSIs sowie deren Grenzen bei der Erreichung von Nachhaltigkeitszielen.
